Description

Technical Field

[0001] This utility model belongs to the field of water pump technology, and more specifically, it relates to a water pump for suction and drainage. Background Technology

[0002] In the fields of drainage and suction, water pumps play a crucial role. Water pumps are machines that transport or pressurize liquids. They transfer the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid's energy. They are mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.

[0003] To ensure stable operation, existing water pumps typically have an annular filter disc installed on the outside of their inlet. Currently, the size of the filter holes on the disc is fixed. Therefore, different sizes of filter discs need to be selected for use in different water environments to maximize the pump's suction and drainage efficiency. If the filter holes are too small, the pump will not be able to draw enough water for drainage. If the filter holes are too large, impurities will enter the pump and cause damage. This results in poor flexibility and adaptability, and limited practicality. Utility Model Content

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0022] As attached Figure 1 To be continued Figure 5 As shown:

[0023] Example 1: This utility model provides a suction and drainage water pump, including a pump body 1 and a filter assembly 2. The filter assembly 2 includes a mounting cover 201, an adjusting cover 202, a positioning rod 203 and a positioning block 204. The mounting cover 201 is fixedly installed at the water inlet of the pump body 1, and the adjusting cover 202 is rotatably connected to the outside of the mounting cover 201. The positioning rod 203 is rotatably connected to the side of the mounting cover 201, and the positioning block 204 is inserted into the inside of the mounting cover 201.

[0024] In this embodiment, both the mounting cover 201 and the adjusting cover 202 are provided with fixed filter holes 2011 on their exteriors, and the adjusting cover 202 is provided with adjustable filter holes 2021. The holes of both the fixed filter holes 2011 and the adjustable filter holes 2021 are diamond-shaped. Both the fixed filter holes 2011 and the adjustable filter holes 2021 are on the same horizontal plane. In use, when the water pump body 1 is in use, it can draw water through the water inlet and pump it out from the water outlet, thereby realizing the function of suction and drainage. Due to the presence of the filter component 2, when the water enters the interior of the water pump body 1, it will be filtered by the overlapping parts of the fixed filter holes 2011 and the adjustable filter holes 2021, thereby blocking the impurities in the water and preventing them from entering the interior of the water pump body 1, ensuring the stable and efficient operation of the water pump body 1 and stable use.

[0025] In this embodiment, the positioning rod 203 has threads on its outer surface and is screwed into the positioning block 204 via these threads. During use, the filter assembly 2 has the function of adjusting the size of the filter holes, thus adapting to suction and drainage in water bodies of different environments. When the positioning rod 203 is rotated, it can drive the positioning block 204 to move via the threads. The bottom of the adjusting cover 202 has a positioning groove 2022, and the top of the positioning block 204 has a positioning lever 2041. The positioning lever 2041 is inserted into the positioning groove 2022. When the positioning block 204 moves, the positioning lever 2041 can drive the adjusting cover 202 to rotate via the positioning groove 2022. 02 When rotating, the position of the adjustable filter hole 2021 can be changed. Changing the position of the adjustable filter hole 2021 changes the effective overlap area between the adjustable filter hole 2021 and the fixed filter hole 2011, which is the effective particle size when filtering impurities in the water. When the filter hole is adjusted to a suitable size, it can ensure the maximum pumping and drainage efficiency of the water pump body 1, and also prevent impurities from entering the interior of the water pump body 1 and causing damage to the water pump body 1. It is easy to adjust, and the threaded transmission has the characteristic of unidirectional transmission. Therefore, when the positioning rod 203 is not subjected to external force, it will not rotate, and the position of the positioning block 204 will also be fixed. During use, there will be no accidental change in the size of the filter hole. It has strong adaptability and stability.

[0026] In this embodiment, the positioning block 204 has a "T" shaped cross-section, and the mounting cover 201 has a track groove 2012 inside. The positioning block 204 is inserted into the track groove 2012. The track groove 2012 can restrict the movement trajectory of the positioning block 204, so that the positioning block 204 will not be tilted or twisted when moving, which would cause the device to jam and fail, and the device is stable in use.

[0027] In this embodiment, the outlet of the water pump body 1 is designed in a stepped shape. In use, the stepped design of the outlet allows the water pump body 1 to be assembled with pipes of different inner diameters. By fitting the pipe onto the outer wall of the appropriate part of the outlet, the pipe can fit tightly against the outer wall of the outlet. Subsequently, the connection between the pipe and the outlet can be achieved through corresponding clips. The complete fit between the pipe and the outer wall of the outlet also avoids leakage during use, further improving the stability of the device.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In this invention, after connecting the pipe to the outlet, the pump body 1 is placed in the water area to be pumped and drained. Once the power to the pump body 1 is turned on, the pumping and draining operation can begin. The stepped design of the outlet allows the pump body 1 to be used with pipes of different inner diameters. By fitting the pipe onto the appropriate part of the outlet's outer wall, the pipe can fit tightly against the outlet's outer wall. Subsequently, the connection between the pipe and the outlet can be achieved using appropriate clips. The complete fit between the pipe and the outlet's outer wall also avoids… To prevent leakage during use, the water pump body 1 draws water through the inlet and pumps it out through the outlet, thus achieving the function of suction and drainage. Due to the presence of the filter assembly 2, water is filtered by the overlapping portion of the fixed filter holes 2011 and adjustable filter holes 2021 before entering the water pump body 1. This prevents impurities from entering the water pump body 1, ensuring stable and efficient operation. The filter assembly 2 has… The filter pore size can be adjusted to adapt to different water environments for pumping and drainage. When the positioning rod 203 is rotated, the positioning rod 203 can drive the positioning block 204 to move through the rod thread. When the positioning block 204 moves, the positioning lever 2041 can drive the adjustment cover 202 to rotate through the positioning slot 2022. When the adjustment cover 202 rotates, it can change the position of the adjustable filter pore 2021. The change in the position of the adjustable filter pore 2021 changes the effective overlap area between the adjustable filter pore 2021 and the fixed filter pore 2011, which is the effective particle size when filtering impurities in the water. When the filter pore is adjusted to a suitable size, it can ensure the maximum pumping and drainage efficiency of the water pump body 1, and also prevent impurities from entering the interior of the water pump body 1 and causing damage to the water pump body 1. The adjustment is convenient, and the threaded transmission has the characteristic of unidirectional transmission. Therefore, when the positioning rod 203 is not subjected to external force, it will not rotate, and the position of the positioning block 204 will also be fixed. The function of changing the filter pore size will not occur unexpectedly during use.
