The invention is related to the technical field of swimming devices, and more particularly related to a swimming training apparatus.
At present for common ground pools and assembled ground pools, due to space constraints, generally only for family fun, cannot be used as swimming training purpose. Currently, swimming training devices in the market are mainly installed in ground swimming pools and include axial-flow type swimming training devices and jet type swimming training devices. The axial-flow type training devices generally use hydraulic transmission system or direct-current power supply. The hydraulic transmission devices are relatively heavy and high cost. The direct-current power supplied device is low power and low water dynamic, and therefore the training effect is not ideal. While for the above-mentioned jet-type swimming training device, the water flows are concentrated on several points and would directly hit human faces easily, thus leading to bad user experience.

Furthermore, as shown in
When the swimming training apparatus in this embodiment is installed for use initially, the second pneumatic switch 14 is pressed to start up the filter pump 9, the filter pump 9 pumps the water in the swimming pool to the inlet pipe 7 by the filter core and further into the swimming pool by the swimming pump 5. The process expels the air in the swimming pump 5, i.e., the swimming pump 5 is evacuated and the swimming pump 5 is brought into a normal operation state. When the filter pump 9 operates to a preset time, the filter pump 9 stops automatically, and the swimming pump 5 starts to operate by the first pneumatic switch 13, and at this moment, water flows into the swimming pump 5 by the inlet pipe 7 and ejects into the swimming pool from the jet connector 11 by the outlet pipe 8. The continuous water cycle makes the swimming pool form a flowing “river” and to facilitate swimming training. Wherein the water in the inlet pipe 7 is mainly directly drawn from the swimming pool and a small amount of water comes into the outlet pipeline 15 of the filter pump 9 by the inlet pipeline of the filter pump 9 and converges to the inlet pipe 7.
In this embodiment, the filter mechanism may filter the water in the swimming pool directly. When the second pneumatic switch 13 is pressed, the filter pump 9 started, the water flows from the swimming pool though the filter core 10, the filter pump 9, the outlet pipeline 15 of the filter pump 9, the inlet pipe 7, the swimming pump 5, and the outlet pipe 8 to the swimming pool, to achieve the filtering of the pool.
In order to facilitate the installation and use of the swimming training apparatus in this embodiment, as shown in

The swimming pump 4 and the distribution box 5 are both included on the bearing plate 164. In this embodiment, the height of the swimming pump 4 and the power distribution box 5 could be adjusted by lifting the bearing plate 164 to adapt to swimming pools with various wall heights.
Furthermore, the second housing is connected to a support rod (not shown) for connecting the second housing to a swimming pool to secure the position between the swimming training apparatus and the swimming pool in this embodiment.
In order to facilitate height adjustment, in this embodiment, the height adjustment structure 16 comprises an upper housing and a lower housing formed the second housing and a rotation adjustment bolt 161 distributed at each edge of the second housing. The bearing plate 164 is fixedly connected to the upper housing. A thread hole is included in the upper housing, one end of the rotation adjustment bolt 161 disposed in the thread hole, the other end of the rotation adjustment bolt 161 abutted against the lower housing. The rotation adjustment bolt 161 is included with a rotation sleeve 162, one end of the sleeve 162 rotatably connected to the upper housing. The rotation of the sleeve 162 drive the rotation adjustment bolt 161 to move up and down in the thread hold, and then drive the bearing plate 164 to move up and down. The threaded hole in the upper housing is formed by a threaded sleeve, which is integrated with the rotation sleeve 162. A positioning sleeve 163 for positioning is included at the other end of the rotary adjustment bolt 161. The in-situ swimming pool of the present embodiment is adapted to swimming pools with different heights by rotating the rotating sleeve to make the rotary adjustment bolt 161 move up and down along the upper housing.
