In a preferred embodiment of the present invention, a fixed ring for inserting the guide rod extendedly disposed on the end of the rear bracket which is distant from the pillar.
The beneficial effect of the invention is that the switch part and the water pump main body of the device are integrally packaged, and the connection of the switch and the motor adopts is in the form of an inserting pin, so the assembly structure is simple, and the operation is convenient. The integrated structure is not easy to be damaged in the process of transportation, and the application prospect is wide.
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below. Obviously, the drawings in the following description are merely some embodiments of the present invention. For those who skilled in the art, other drawings may also be obtained based on these drawings without paying any creative work. Therein:
The following is clearly and completely describes of the technical solutions in the embodiments of the present invention. Apparently, the described embodiments are merely some but not all embodiments of the present invention. All other embodiments obtained by a person who is skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
Referring to
A vertical-shaft sewage pump with anti-collision switch includes a water pump driving component 1, a switch control component 2, a base 3 and a post 4 fixed on the base 3, the water pump driving assembly 1 includes a driving motor 11 and a casing 12 sleeved on the outside of the driving motor 11, an upper end cover 13 and a lower end cover 14 which respectively fixed at the upper end and the lower ends of the casing 12. A plurality of cylindrical bosses 5 is disposed on the lower surface of the lower end cover 14. The cylindrical bosses 5 are provided with internal threads. Screws 20 are provided at the corresponding positions of the upper surface of the switch box 21, and the switch control assembly 2 is installed to the lower side of the water pump drive assembly 1 via the screws 20 engaged with the internal threads provided on the cylindrical bosses 5. The switch control assembly 2 also includes a micro switch 22 housed inside the switch box 21, a guide rod 23 and a floating ball 24 which is movable up and down along the guide rod 23. A magnetic portion is provided at an end of the guide rod 23 that protrudes into one end of the switch box 21. The upper and lower sides of the floating ball on the guide rod 23 are respectively provided with an upper position limitation ring 25 and a lower position limitation ring 26. An electrical connection part 6 is disposed between the water pump drive assembly 1 and the switch controlling component 2. The electrical connection part 6 includes a tab 61 which electrically connected with the drive motor 11, a base 62 disposed on the upper surface of the switch box 21 and a pin 63 inserting in the base 62, the upper end of the pin 63 is connected with the tap 61, and the lower end is connected with the micro switch 22 in the water pump driving assembly via a wire.
Further, a convex plate 7 is outwardly extended from the upper surface of the upper end cover 13, a circular hole is provided on the convex plate 7, and the circular hole is penetrated with a hand ring 8. The handle ring 8 is not limited to a circle shape, a triangle shaped ring, or a square shaped ring, which is convenient for putting on and taking off during transportation and carrying are also applicable.
Further, the bracket assembly 9 includes a front bracket 91 and a rear bracket 92. The front bracket 91 and the rear bracket 92 are connected by screws at one ends, and the other ends of them are pivotally connected via a round pin extended in a through hole. To gain an anti-slip effort, the inner surface of the front bracket 91 and the rear bracket 92 is vertically provided with non-slip guiding grooves 93. A ring-shaped fixation ring 94 disposed on the end of the rear bracket 92 which is distant from the pillar 4. And the guide rod 23 is inserted into the fixation ring 94 and plays a fixation and supporting role therein.
During operation, when the water level rises and the float ball moves upwards, when the water reaches the upper water level, the float ball touches the upper limitation position circle and brings the guide rod to move upwards. The micro switch in the switch box is triggered to drive the motor to rotate and the water pump starts to work. When the water drops, the float ball moves downwards. When the water reaches the lower water level, the float ball touches the lower limitation circle and brings the guide rod to move upwards. The micro switch resets, the motor stops rotating, and the water pump stops working.
In summary, the vertical-shaft sewage pump with anti-collision switch of the present invention has a simple mechanism structure and it is easy to operate. The switch part and the pump body are integrally packaged, and the switch and the motor are connected in the form of pin-inserting, and the assembly structure is simplified. The integral structure is not easy to damage during transportation and has a wide application prospect.
The foregoing descriptions are merely embodiments of the present invention, and therefore do not mean to limit the scope of the present invention. Any implementation on the content of the present specification by using an alternative structure or equivalent process transformation, or, a direct or indirect application in the same field or in other related technical fields is in the protection scope of the present invention.
