Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps, and in particular relates to a water pump. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. It can also transport liquids, gas mixtures and liquids containing suspended solids.

[0003] During use, existing water pumps are often troubled by impurities and large particles in the water pipes. These impurities and large particles gradually accumulate in the water inlet pipe, which will not only significantly reduce the water intake, resulting in a significant decrease in the pumping efficiency of the water pump, but also in severe cases, the water inlet pipe may even be completely blocked, causing the water pump to completely lose its ability to work. What is more serious is that the accumulated impurities and large particles will continuously hit the internal blades, bearings and other core components during the operation of the water pump, causing wear and even damage to these components. If this continues for a long time, not only will the performance of the water pump be seriously affected, but its service life will also be greatly shortened. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] See also Figure 1-5 , the technical solution provided by this embodiment is as follows:

[0027] A water pump comprises a main body 1, a water inlet pipe 2 is arranged on one side of the main body 1, a drain pipe 3 is arranged on the top of the main body 1, sealing mechanisms 4 are arranged at the ends of the water inlet pipe 2 and the drain pipe 3, a cleaning mechanism 5 is arranged inside the water inlet pipe 2, the cleaning mechanism 5 comprises a fixing frame 501, a waterproof motor 502, a rotating shaft 503, a crushing blade 504, a filter screen 505 and a bearing 506, the fixing frame 501 is fixedly installed on the inner wall of the water inlet pipe 2, the waterproof motor 502 is fixedly installed on one side of the fixing frame 501, the rotating shaft 503 is fixedly connected to one side of the waterproof motor 502, the crushing blade 504 is fixedly installed on the end of the rotating shaft 503, the filter screen 505 is fixedly installed on the inner wall of the water inlet pipe 2, and the bearing 506 is fixedly installed in the middle part of the filter screen 505.

[0028] See also Figure 1-5 The rotating shaft 503 passes through the other side of the fixed frame 501, the filter screen 505 is located between the fixed frame 501 and the crushing blade 504, the crushing blade 504 is close to the inlet of the water inlet pipe 2, the rotating shaft 503 is movably installed on the inner side of the bearing 506, a fixing plate 6 is provided at the bottom of the main body 1, the drain pipe 3 is fixedly connected to the fixing plate 6 through a support plate, and fixing blocks 7 are provided around the fixing plate 6, and fixing holes 8 are opened on the surface of the fixing blocks 7.

[0029] Specifically, the main body 1 is the core part of the whole device, which accommodates all important working parts and provides them with a stable working environment. The water inlet pipe 2 is responsible for introducing water or other liquids into the water pump, and the drain pipe 3 is used to discharge the liquid pressurized by the water pump to realize the liquid transportation or pressurization function. The cleaning mechanism 5 can prevent the water inlet pipe 2 from being blocked. The waterproof motor 502 drives the rotating shaft 503 to rotate, and then drives the crushing blade 504 to pre-treat the incoming liquid and crush possible solid particles. The filter screen 505 can filter out large particles in the liquid to prevent them from entering the water pump and causing damage. The installation of the bearing 506 makes the rotation of the rotating shaft 503 smoother and extends the service life of the mechanism. The fixing plate 6, the support plate, the fixing block 7 and the fixing hole 8 together constitute a stable support and fixing structure of the water pump. The support plate provides a stable support for the drain pipe 3, and the fixing block 7 and the fixing hole 8 allow the entire water pump to be conveniently fixed in the desired position to prevent movement and vibration during operation.

[0030] Embodiment 2:

[0031] See also Figure 1 , Figure 2 and Figure 4 The sealing mechanism 4 includes a flange 401, a block 402, a mounting groove 403 and a sealing rubber ring 404. The flange 401 is fixedly installed at the ends of the water inlet pipe 2 and the drain pipe 3. The block 402 is fixedly installed on one side of the flange 401. The mounting groove 403 is opened on the outer side of the block 402, and the sealing rubber ring 404 is sleeved on the inner side of the mounting groove 403.

[0032] Specifically, by setting up the sealing mechanism 4, the leakage of liquid at the ends of the water inlet pipe 2 and the drain pipe 3 is effectively prevented, thereby ensuring the normal operation of the water pump. The flange 401 serves as a connecting component and provides a stable connection structure. The block 402 can be inserted into the inside of the connecting water pipe. The mounting groove 403 can fix the sealing rubber ring 404. The sealing rubber ring 404 directly prevents the leakage of liquid and ensures the sealing effect.

[0033] Working principle: First, when the water pump starts working, the liquid enters the main body 1 of the water pump through the water inlet pipe 2. In this process, the cleaning mechanism 5 plays a key role. After the waterproof motor 502 is started, the driving shaft 503 starts to rotate. The rotation of the shaft 503 drives the crushing blade 504 fixed at its end to rotate together. When the liquid enters the water inlet pipe 2, the crushing blade 504 will crush the solid particles therein to ensure that these particles will not block the water inlet pipe 2 or cause damage to the internal components of the water pump. The crushed liquid then flows through the filter screen 505. The function of the filter screen 505 is to further filter out large particles of impurities in the liquid to ensure that only clean liquid enters the main body 1 of the water pump. The presence of the bearing 506 makes the rotation of the shaft 503 smoother, reducing friction and wear. Thereby, the service life of the cleaning mechanism 5 is extended. The liquid processed by the cleaning mechanism 5 enters the main body 1 of the water pump, where the liquid is pressurized and pushed to the drain pipe 3. The drain pipe 3 is fixedly connected to the fixing plate 6 through the support plate to ensure its stability during operation, and the setting of the sealing mechanism 4 effectively prevents the leakage of the liquid at the end of the drain pipe 3. The working principle of the sealing mechanism 4 mainly depends on the synergistic effect of the flange 401, the block 402, the installation groove 403 and the sealing rubber ring 404. The flange 401 is used as a connecting component to provide a stable connection structure. The block 402 is inserted into the interior of the connecting water pipe and the sealing rubber ring 404 is fixed by the installation groove 403. When the sealing rubber ring 404 is subjected to the squeezing force of the water pipe, it can fit tightly to the connecting part, thereby effectively preventing the leakage of the liquid.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
