[0020] 3. When the four water flow buffer plates pull one side of the annular push frame toward the inner wall of the filter support frame, the diameter of the annular push frame becomes larger, and the annular push frame pushes the garbage away from the center of the filter, causing the garbage to be concentrated on the hollow positioning ring, avoiding excessive garbage clogging the filter and affecting the filtration of water flow;

[0021] 4. Part of the water flow will leak into the water collection area. The water flow buffer plate moves toward the center of the filter through the push of the folding tube, and the water pipe is tightly attached to the inner wall of the filter device support frame, thereby reducing the gap between the two, avoiding excessive water loss and causing losses to residents, and giving staff sufficient time to repair the water inlet pipe.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] like Figure 1 - Figure 3As shown, the present invention proposes a quick-detachable filtering device for the front end of the water inlet pipe of a water supply pump, including a water pipe assembly 1, the water pipe assembly 1 includes a filtering device support frame 101, the interior of the filtering device support frame 101 is provided with a cavity, and a water pipe 103 plugged into one side of the filtering device support frame 101 through a sealing rubber ring 104, the sealing rubber ring 104 is used to fit tightly with the water pipe 103 to prevent leakage when water flows from the water pipe 103 into the filtering device support frame 101, the interior of the filtering device support frame 101 is fixedly connected with two isolation ring blocks 105, the filtering device support frame 101 is divided into two water collection areas and a central filtering area by the two isolation ring blocks 105, the pushing assembly 4 is located in the central filtering area, and the two water collection areas are used to receive the water pipes. The water collected by leakage at the connection between 103 and the filter device support frame 101 is mainly used for filtering with the filter screen 206 in the central filtering area, and the water flow is blocked by the isolation ring block 105 to prevent the water flow from flowing into the interior of the pushing assembly 4 and interfering with the components included in the pushing assembly 4. The filter device support frame 101 is located between the two isolation ring blocks 105 and is connected with multiple plug-in blocks 102 by bolts. The fixed long rod 404 is fixedly installed on the inner wall of the plug-in block 102. When it is necessary to clean the garbage accumulated on the hollow positioning ring 202 and replace the new filter screen 206, the staff removes the connecting bolts between the plug-in block 102 and the filter device support frame 101, cleans the garbage on the hollow positioning ring 202 and replaces the new filter screen 206.

[0032] like Figure 1 - Figure 3, a water flow buffer component 2 for buffering water flow impact is installed inside the water pipe component 1, a water weight regulating sealing component 3 is installed on one side of the water flow buffer component 2, and the water flow buffer component 2 is located between the water pipe component 1 and the water weight regulating sealing component 3, and a pushing component 4 for adjusting the looseness of the filter according to the size of the water flow impact is installed on the outside of the water flow buffer component 2, the water flow buffer component 2 includes a hollow positioning ring 202 fixedly installed on the inner wall of the filter device support frame 101, a filter 206 is inserted in the center of the hollow positioning ring 202, and the two sides of the hollow positioning ring 202 are slidably connected with the same number of positioning sliders 208 through four slideways 204, and a spring telescopic rod 205 is fixedly connected between the slideway 204 and the positioning slider 208, a water flow buffer plate 201 is hinged on one side of the positioning slider 208 through the positioning ring rod 203, and the side of the water flow buffer plate 201 away from the positioning slider 208 is installed on the water weight regulating sealing component 3, and one side of the four water flow buffer plates 201 is affected by the water weight regulating sealing component 3 When the water flow buffer plate 201 is limited, the other side of the water flow buffer plate 201 drives the positioning slider 208 to slide on the slideway 204 through the positioning ring rod 203. The four water flow buffer plates 201 and the water weight regulating sealing component 3 are arranged in an axisymmetric state about the horizontal center line of the filter screen 206. When the water flow of the water inlet pipe flows to the filter screen 206, the impact force of the water flow first pushes the water flow buffer plate 201, and the water flow buffer plate 201 deflects along the connection of the positioning slider 208. At the same time, the positioning slider 208 is located on the spring telescopic rod 2 05 slides along the slideway 204 under the limitation of the internal spring, buffers the impact of the water flow, reduces the impact force on the filter 206, and extends the service life of the filter 206. Under the limitation of the four groups of water flow buffer plates 201, the water flow is limited and concentrated to the central position, and is fully in contact with the filter 206 to achieve filtration. The water flow filtered by the filter 206 circulates under the limitation of the four water flow buffer plates 201 on the other side of the filter 206, thereby improving the filtering effect of the water flow.

[0033] like Figure 3 and Figure 7The water flow buffer plate 201 and the water pipe 103 are fixedly connected with a limited position pull rope 207. The water weight regulating sealing component 3 includes a folding tube 304 fixedly installed on one side of the water flow buffer plate 201, and the folding tube 304 is normally set in a compressed state. In the compressed state, the folding tube 304 is affected by the constant airflow of the hollow airbag 301. The connection between the water flow buffer plate 201 and the folding tube 304 remains relatively fixed, and the connection between the water flow buffer plate 201 and the folding tube 304 will not be impacted by the water flow toward the filter device. The inner wall of the support frame 101 moves, and the folding tube 304 passes through one side of the inner wall of the filter device support frame 101 and is fixedly connected to a connecting tube positioning block 302. The connecting tube positioning block 302 is fixedly installed on the inner wall of the filter device support frame 101. Two auxiliary air flow transmission tubes 303 are fixedly connected on both sides of the connecting tube positioning block 302. The two auxiliary air flow transmission tubes 303 are connected to the folding tube 304 in a connected state. The bottom of the two auxiliary air flow transmission tubes 303 is fixedly connected to a hollow air bag 301. The two auxiliary air flow transmission tubes 303 are connected to the hollow air bag 301 is arranged in a connected state, and the hollow airbag 301 is fixedly installed on the inner wall of the filter device support frame 101. When the bolts connected at the connection between the water pipe 103 and the filter device support frame 101 are aged or the sealing rubber ring 104 is aged and leaks, when the water flow leaks from the gap between the water pipe 103 and the filter device support frame 101, part of the water flow will leak into the water collection area. As too much water flow accumulates in the water collection area, the weight of the water flow will gradually press down the hollow airbag 301. After the hollow airbag 301 is compressed, the air flow inside It will flow into the folding tube 304 through the auxiliary air flow transmission tube 303, and the folding tube 304 will change from a compressed state to an extended state, and the water flow buffer plate 201 will move toward the center of the filter screen 206 through the push of the folding tube 304. At this time, the water flow buffer plate 201 will pull the water pipe 103 through the limiting pull rope 207, and the water pipe 103 will be tightly attached to the inner wall of the filter device support frame 101, thereby reducing the gap between the two, avoiding excessive water loss and causing losses to residents, and giving staff sufficient time to repair the water inlet pipe.

[0034] In this embodiment, Figure 1 - Figure 4The hollow positioning ring 202 is located between the plug-in block 102 and the filter device support frame 101 and is fixedly connected with a spring 403. The side of the spring 403 away from the filter device support frame 101 is fixedly installed on the outside of the push folding rod 401. The pushing component 4 includes a filter screen pulling rod 402 fixedly installed on the side of the filter screen 206 located inside the hollow positioning ring 202. The inner wall of the filter device support frame 101 is slidably connected with the push folding rod 401. The push folding rod 401 is slidably installed in the filter screen through the limiting sliding cavity block 405 on one side of the filter screen pulling rod 402. A fixed long rod 404 is slidably installed on one side of the filter pulling rod 402 and the limiting sliding cavity block 405. When the water flow hits the water flow buffer plate 201, the greater the force of the water flow or the greater the amount of water flow outlet, the greater the angle of deflection of the water flow buffer plate 201 along the positioning slider 208, and the greater the sliding distance of the positioning slider 208 along the slideway 204. At this time, the side of the water flow buffer plate 201 contacts the pushing folding rod 401, and the pushing folding rod 401 slides along the filter device support frame 101 toward the plug-in block 102. The pushing folding rod 401 is pressed against the spring 40 3, the filter screen pulling rod 402 slides along the limiting sliding cavity block 405, and the pushing folding rod 401 moves to the inner wall of the limiting sliding cavity block 405 facing the plug-in block 102, and when it is in contact with it, the filter screen pulling rod 402 is subjected to a force toward the plug-in block 102 through the limiting sliding cavity block 405, and the filter screen pulling rod 402 pulls the filter screen 206 to slide inside the hollow positioning ring 202. A limiting block is set at the connection between the filter screen pulling rod 402 and the fixed long rod 404, so that the filter screen pulling rod 402 slides in the sliding hole opened in the fixed long rod 404. The row spacing is limited. When subjected to a large water flow impact, the filter mesh pulling rod 402 will pull the filter mesh 206 to be straightened. The filter mesh pulling rod 402 supports the filter mesh 206 through the thrust converted by the water flow impact, thereby preventing the filter mesh 206 from being excessively relaxed when the water flow impacts the filter mesh 206, thereby failing to achieve a good filtering effect. Similarly, if the water flow is small, the filter mesh 206 is in a normal state for filtering, thereby preventing the filter mesh 206 from being in a straightened state all the time and being often damaged by the water flow impact, thereby extending the service life of the filter mesh 206.

[0035] Metal filter meshes are prone to oxidation after long-term filtration, which may release harmful substances and affect the water quality. Therefore, the filter mesh 206 can be made of plastic or cotton materials that are easy to replace.

[0036] like Figure 5 - Figure 6A telescopic annular component 5 is installed on one side of the water flow buffer component 2. The telescopic annular component 5 includes a plurality of sliding cavity blocks 503 fixedly installed on the surface of the hollow positioning ring 202. A telescopic annular push frame 501 is slidably connected to one side of the sliding cavity block 503. A pull rope 502 is fixedly connected between the annular push frame 501 and the water flow buffer plate 201. As the water flow impacts, the water flow buffer plate 201 deflects along the positioning slider 208. The four water flow buffer plates 201 move toward one side of the inner wall of the filter device support frame 101 by pulling one side of the annular push frame 501. The diameter of the annular push frame 501 becomes larger, and the annular push frame 501 pushes the garbage away from the center of the filter screen 206, causing the garbage to be concentrated on the hollow positioning ring 202, thereby avoiding excessive garbage from clogging the filter screen 206 and affecting the filtration of the water flow.
