Description of Related Art
Most of the available outdoor aquacultures are located in open areas. In summers, the water temperature of the aquacultures is raised. In winters, the water temperature is decreased. Especially when cold stream comes, the water temperature will be decreased in a greater magnitude. Since the fishes and shrimps are cold-blooded, the body temperature thereof will be decreased as the environmental temperature is decreased. When the body temperature is too low, problems of poor blood circulation and oxygen deficient will occur to cause death.
Most of the presently adopted winter protection methods are building wind scaffoldings, digging wintering trenches, covering styrofoam plates or bubble cloth, extracting groundwater, or erecting heat lamps or electric heaters. However, using those methods have drawbacks. For example, cold wind can blow into aquacultures from the gaps between wind scaffoldings, and the insulation effect to keep the water temperature of the aquaculture is limited. In another example, the wintering trenches may keep the water temperature of the deep water at a temperature of about 4° C. However, when cold stream comes, the cultured fishes and shrimps may still be frozen to death caused by the water convection. In yet another example, covering styrofoam plates or bubble cloth above the water may decrease the water convection under low temperature to decrease the heat loss, but the dissolved oxygen in the water may be deficient to make the cultured fishes and shrimps dead since oxygen deficient. In yet another example, extracting the ground water having a higher temperature can raise the water temperature of the aquaculture, but it will cause land subsidence. Erecting heat lamps or electric heaters surrounding aquacultures can only increase the water surface temperature at most, since the heat lamps or electric heaters cannot be immersed in the water and thus only limited winter proofing effect is produced.
Therefore, in view of the drawbacks of the adopted winter proofing methods above, which cannot effectively prevent the fishes and shrimps from being frozen to death when cold winter comes, the inventors develop this invention by the many-year manufacturing and design experience and knowledge in the related fields and ingenuity.
This invention is related to an aquaculture heating device. One main aspect is to provide an aquaculture heating device having a heating unit on a support rod, and the heating unit is immersed in water to directly heat the water for avoiding the aquatic organisms being frozen to death.
For reaching the practical purposes, the inventors invent the following aquaculture heating device, which comprises:
at least a heating unit having at least two waterproof fabric layers covering a heating layer, wherein the heating layer comprises at least a heating fabric comprising multiple conductive yarns in a first direction and multiple nonconductive yarns in a second direction, as well as multiple metal conductive filaments disposed on two sides of the heating fabric and in a direction parallel to the second direction to be interwoven with the conductive yarns in the first direction, wherein the conductive yarns and the nonconductive yarns are interwoven as warps and wefts, and wherein the conductive yarns each has a nonconductive axial yarn spiral-wound by a heating filament; and
a suspension unit comprising a support rod having at least a binding part, wherein one terminal of the binding part disposed on the support rod and the other terminal of the binding part assembled with the heating unit.
In the aquaculture heating device above, the heating layer comprises multiple heating fabrics and a fixing element for fixing the heating fabrics.
In the aquaculture heating device above, a diameter of the heating filaments of the conductive yearns in the heating fabric is 0.02-0.12 mm.
In the aquaculture heating device above, a winding number of the heating filaments of the conductive yarns on the axial yarns in the heating fabric is 70-125 circles/cm.
In the aquaculture heating device above, a distribution width of is the metal conductive filaments on two sides of the heating fabric is about 0.6-1.0 cm.
In the aquaculture heating device above, a diameter of the metal conductive filaments is 0.05-0.12 mm.
In the aquaculture heating device above, the metal conductive filaments on two sides of the heating fabric are collectively connected to one ends of two conductive wires, and the other ends of the two conductive wires are penetrated outwardly from the waterproof fabric layer.
In the aquaculture heating device above, the other ends of the two conductive wires of the heating layer of the heating unit that outside the waterproof fabric layer are electrically connected to a power supply unit converting AC electricity to DC electricity and being connected to a control unit.
In the aquaculture heating device above, one end of the support rod of the suspension unit is further connected to a furling unit having a motive power unit.
In the aquaculture heating device above, the motive power unit is one of an electrical power unit and a manual power unit.
Therefore, when winter, especially cold stream, comes, the support rod can be horizontally placed above an aquaculture, two ends of the support rods are positioned on two sides of the aquaculture, so that the heating unit hung on the support rod can be immersed in the water of is the aquaculture. When electricity is provided to the conductive yarns of the heating layer in the heating unit, the heating filaments in the conductive yarns will generate heat and the heat can be transferred to water through the outer waterproof fabric layer and diffused to the surrounding corners to raise the water temperature of the aquaculture. Therefore, the aquatic organisms in the aquaculture can resist the cold winter to avoid being frozen to death caused by the very low water temperature.

The suspension unit 2 comprises a support rod 21. One end of a binding part 22 is disposed on the support rod 21, and the heating unit 1 is disposed on the other end of the binding part 22. The binding part 22 may be a sling. A standing frame body 23 is assembled on two ends of the support rods 21.
A power supply unit 3 is electrically connected to the other ends of the two conductive wires 18 penetrating outwardly from the waterproof fabric layer 11. The power supply unit 3 is equipped with a plug to connect with a socket of an electric supply to decrease the AC voltage of 110-220 V to a DC power supply with low voltage of 6 V, 12 V, 24 V, and 48 V. The power supply unit 3 is electrically connect to a control unit, which controls the heating temperature, time and on/off
Accordingly, the heating fabric 13 is manufactured by a conductive-yarn manufacturing device 4, please refer to
When a conducive yarn is made, the spindle of the nonconductive yarn is fixed on the spindle fixed disk 47 at the bottom of the body 40 to provide the nonconductive axial yarn 151 wound by a heating filament 152. The heating filament 152 circles on the reel 44 above the rotating seat 43. Subsequently, the spindle furling disk 481 assembled with the second motive power source 48 pull the axial yarn 151 guided by several guiding wheels 49 assembled on the body 40 to let the axial yarn 151 penetrate the central axial hole 421 of the axial rod 42, and then the axial yarn 151 is pulled up to be delivered to the reel 44 circled by the heating filament 152. The rotating wheel 431 is driven by the first motive power source 46 through the driving wheel 461 to make the reel 44 assembled on the rotating seat 43 rotate in a high speed, so that the heating filament 152 can be parabolically thrown out to spirally circle the axial yarn 151 to form the conductive yarn 15 of this invention. The conductive yarn 15 is pulled, transferred, and rotatively received by the spindle furling disk 481 through the several guiding wheels 49 in a certain direction. A recorder is set at the position of the spindle furling disk 481 to calculate the length of the conductive yarn 15 received by the spindle furling disk 481. When a predetermined length of the conductive yarn 15 on the spindle furling disk 481 is reached, the conductive yarn 15 may be sent to a textile factory to be a weft when knitting. The conductive yarn 15 as the weft can be spun with the nonconductive yarn 16 containing multi-core filaments as the warp to form the heating fabric 13.
When winter, especially cold stream, comes, a user can take the aquaculture heating device of this invention to horizontally place the support rod 21 of the suspension unit 2 above an aquaculture. The frame bodies 23 are used to support the support rod 21 and positioned on two sides of the aquaculture. At this time, the heating unit 1 hung on the support rod 21 will naturally fall down to be immersed in the water of the aquaculture. The user can set up several aquaculture heating devices in one aquaculture. Therefore, when these aquaculture heating devices are used, the user can turn on the power supply unit 3 through the control unit to convert the AC power of 110-220 V to a DC power of 12 V or 24 V and then output the DC power through the conductive wires 18 to the metal conductive filaments 17 of the heating fabric 13 of the heating unit 1 and then the conductive yarns 15. Thus, the conductive filaments 152 of the conductive yarns 15 can generate heat to be transferred to the water through the waterproof fabric layer 11 and then throughout the aquaculture to raise the temperature of the water in the aquaculture. Therefore, the aquatic organisms, such as fishes and shrimps, will not be frozen to death caused by the very low water temperature. In addition, the heating temperature and time can be adjusted by the control unit, depend on the water temperature. The heating temperature and time may be increased as the water temperature is decreased to more effectively prevent the aquatic organisms from being frozen to death. Especially, low voltage and small current is used to provide electricity to the heating fabric 13 for generating heat. Hence, the power consumption can be effectively decreased. Moreover, the harm of the electromagnetic wave to the aquatic organisms can be decreased, and the current leakage under high voltage can be avoided to prevent the aquatic organisms from being killed by electric shock.
After the winter or the cold stream, the aquaculture heating device of this invention can be removed from the aquaculture to prevent the heating unit 1 from being damaged by aquatic organisms' biting. Please refer to
