Description

Technical Field

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

[0002] In the existing technical field of water pumps, in order to prevent large-particle impurities or foreign objects from entering the inside of the water pump and causing damage or blockage of the pump body, the common practice is to install a filter screen in the water inlet pipeline of the water pump. This design effectively intercepts impurities in the water to a certain extent and protects the normal operation of the water pump. However, as the use time prolongs, the filter screen will gradually accumulate the intercepted impurities, such as sediment, fibers, small stones, etc. These accumulated impurities will gradually reduce the flow area of the filter screen and ultimately cause the filter screen itself to become blocked.

[0003] Once the filter screen is blocked, the water inlet efficiency of the water pump will drop significantly, and it may even cause failures such as overheating and shutdown of the water pump, seriously affecting the stability and service life of the equipment. To solve this problem, traditional methods often require manual disassembly of the filter screen for cleaning or replacement, which not only increases the maintenance cost but also consumes a lot of manpower and time. Especially in some applications where it is not easy to access or the degree of automation is relatively high, it is even more inconvenient. Content of the Utility Model

The outer surface of the water inlet pipe is fixedly installed with an installation pipe, and the inner wall of the installation pipe is movably installed with a rotating shaft rod. The bottom end of the rotating shaft rod is connected with a ball core, and the top end of the rotating shaft rod is connected with an operation ring. The inner wall of the operation ring is movably installed with a filter cylinder, and the inner wall of the filter cylinder is installed with a filter screen. The outer surface of the top end of the water inlet pipe is provided with a backflush water inlet, and the outer surface of the bottom end of the water inlet pipe is provided with a backflush drain outlet. Threads are provided on the outer surfaces of the backflush water inlet and the backflush drain outlet, and a rotating cover is movably installed on the outer surfaces of the backflush water inlet and the backflush drain outlet.

[0008] Preferably, one side of the rotating cover is connected with a connecting piece, and the connecting piece is installed in the inner walls of the backflush water inlet and the backflush drain outlet. The outer surface of the connecting piece is wrapped with rubber.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following description is merely exemplary in nature and is not intended to limit the present disclosure, its application, and uses. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. Each figure only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the various embodiments of the present disclosure. In a specific part of a specific figure, exaggeration may be used to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0024] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0025] A clog - proof water pump, including a water pump main body 1, a water inlet pipe 2 is arranged at one end of the water pump main body 1, and a water outlet 3 is arranged on one side of the water pump main body 1. An installation pipe 311 is fixedly installed on the outer surface of the water inlet pipe 2, and a rotating shaft rod 4 is movably installed on the inner wall of the installation pipe 311. A ball core 411 is connected to the bottom end of the rotating shaft rod 4, and an operation ring 5 is connected to the top end of the rotating shaft rod 4. A filter cylinder 811 is movably installed on the inner wall of the operation ring 5, and a filter screen 812 is installed on the inner wall of the filter cylinder 811. A back - flushing water inlet 6 is opened on the outer surface of the top end of the water inlet pipe 2, and a back - flushing water drainage port 9 is opened on the outer surface of the bottom end of the water inlet pipe 2. Threads are provided on the outer surfaces of the back - flushing water inlet 6 and the back - flushing water drainage port 9, and a rotating cover 7 is movably installed on the outer surfaces of the back - flushing water inlet 6 and the back - flushing water drainage port 9.

[0026] Furthermore, a connecting piece 711 is connected to one side of the rotating cover 7, and the connecting piece 711 is installed in the inner walls of the back - flushing water inlet 6 and the back - flushing water drainage port 9. The outer surface of the connecting piece 711 is wrapped with rubber. The connecting piece 711 and the rubber enhance the sealing performance between the rotating cover 7 and the back - flushing water inlet 6 and the back - flushing water drainage port 9, preventing water leakage during the back - flushing process. At the same time, the flexibility of the rubber also helps to rotate and fix the rotating cover 7 more smoothly.

[0027] Furthermore, a holding rod 813 is fixedly installed on one side inner wall of the filter cylinder 811. Fixing the holding rod 813 on one side inner wall of the filter cylinder 811 enables the operator to conveniently grasp the holding rod and easily take out the filter cylinder 811 when it is necessary to clean or replace the filter screen 812, improving the convenience and efficiency of maintenance.

[0028] Furthermore, a support seat 911 is fixedly installed at the bottom end of the water inlet pipe 2. The support seat 911 enhances the stability of the entire water pump system, preventing the displacement or damage of the water inlet pipe 2 caused by vibration or external force, and ensuring the normal operation of the water pump.

[0029] Furthermore, a flange 8 is provided on one side of the water inlet pipe 2. The flange 8 can facilitate the connection with other pipeline systems more conveniently, improving the compatibility and installation flexibility of the water pump, and at the same time enhancing the firmness and tightness of the connection.

[0030] Furthermore, both the filter cartridge 811 and the filter screen 812 are made of stainless steel. The stainless steel material has excellent corrosion resistance and wear resistance, can withstand the erosion of water flow and the abrasion of impurities for a long time, extending the service life of the filtration system. At the same time, the stainless steel material is also easy to clean and maintain.

[0031] Furthermore, the outer surface of the filter cartridge 811 is wrapped with rubber, and the rubber enhances the tightness and durability of the filter cartridge 811.

[0032] Working principle: In the normal working state, water flows into the water pump main body 1 through the water inlet pipe 2. During this period, the water first passes through the filter screen 812 inside the filter cartridge 811. The filter screen 812 effectively intercepts the impurities in the water, protecting the water pump main body 1 from being blocked. As the use time accumulates, the impurities on the filter screen 812 will gradually increase. When the water flow smoothness is affected, first, by adjusting the operation ring 5, the rotating shaft rod 4 and the ball core 411 at the bottom are driven to rotate. The design of the ball core 411 enables it to seal the channel of the water inlet pipe 2, so that without affecting the connection of other pipelines, the water flow into the water pump main body 1 is cut off. Then, the rotating cover 7 is opened, and an external flushing water source is connected to the backflush water inlet 6 through the threaded interface. At the same time, ensure that the rotating cover 7 of the backflush drain port 9 is also opened to discharge the flushing water and impurities. The backflush water source is started, and water enters the water inlet pipe 2 from the backflush water inlet 6. Since the channel of the water inlet pipe 2 is blocked by the ball core 411 at this time, the water will flow reversely, directly impacting the surface of the filter screen 812 and the impurities thereon. Under the scouring of the high-pressure water flow, the impurities are effectively removed and discharged from the water pump system through the backflush drain port 9. After the backflush is completed, the backflush water source is closed, and the rotating cover 7 is reinstalled and tightened to prevent water leakage. Subsequently, the operation ring 5 is adjusted again to make the ball core 411 return to its original position, and the channel of the water inlet pipe 2 is reopened, and the water pump can return to the normal working state.
