After the top frame and the bottom frame are inserted into the filter box, a stable anti-detachment measure can be maintained, reducing the probability of accidental detachment between the filter screen frame and the filter box, and improving the stability of the filter screen frame fixed inside the filter box.

[0022] 3. In this utility model, by designing a connecting mechanism, a pipe fitting is connected to the output end of the water pump body. The pipe fitting and the second pipe are connected through a third positioning block, a thread ring and a connecting seat. By rotating the collar to connect or separate the thread ring and the connecting seat, the disassembly and assembly operation of the water pump body can be completed, avoiding the phenomenon of spending more time during disassembly and assembly due to connecting the water pump body and the second pipe by using flanges and bolts, and improving the convenience of disassembly and assembly of the water pump body.

[0036] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0037] Embodiment 1

[0038] As Figures 1-4As shown in the figure, the present utility model provides a technical solution: an anti-blocking mechanism for a water pump, including a water pump body 1. A first pipeline 2 is arranged on one side of the water pump body 1. One end of the first pipeline 2 is fixedly communicated with an anti-blocking component 3. A second pipeline 4 is arranged on one side of the water pump body 1. A connecting mechanism 5 is arranged on one side of the second pipeline 4. The anti-blocking component 3 includes a filter box 31 fixedly communicated with one end of the first pipeline 2. A top frame 32 slides through one side of the filter box 31. A fixing mechanism 33 is arranged on one side of the top frame 32. A bottom frame 34 is arranged on the other side of the top frame 32. One side of the bottom frame 34 slides through one side of the filter box 31, and the other side of the bottom frame 34 is fixedly communicated with one end of a connecting pipe 36 through a first flange. One side of a filter screen frame 38 is in contact with one side of the bottom frame 34. By arranging the filter screen frame 38, a filter screen frame 38 is arranged inside the filter box 31. The filter screen frame 38 is used to filter and collect impurities in the water flow, so that the impurities have good filtering measures, avoiding the blockage of the water pump body 1 by the impurities, improving the anti-blocking measures of the water pump body 1, and improving the normal working efficiency of the water pump body 1. One side of the bottom frame 34 is fixedly connected with a side plate 35. One side of the second pipeline 4 is fixedly communicated with a connecting pipe 36. An anti-detachment mechanism 37 is arranged on the other side of the filter box 31. A filter screen frame 38 is arranged on the other side of the top frame 32.

[0039] In this embodiment, when in use, when the water pump body 1 works, the water flow enters the interior of the filter box 31 from the first pipeline 2. The water flow contacts the filter screen frame 38 inside the filter box 31. The filter screen frame 38 is a corrugated filter screen. When the water flow contacts the filter screen frame 38, the impurities in the water flow are filtered through the filter screen frame 38. The water flow after impurity filtration passes through the filter screen frame 38 and flows into the interior of the second pipeline 4, while the impurities filtered by the filter screen frame 38 remain on the filter screen frame 38. When the filter screen frame 38 filters the impurities in the water flow, the larger impurities will gradually move to the lower part of the filter screen frame 38 due to the shape of the filter screen frame 38 and the slight vibration generated when the filter screen frame 38 is impacted by the water flow until the impurities move to the lowest part of the filter screen frame 38 and stay at the lowest part. The bottom frame 34 at the corresponding position at the lowest part of the filter screen frame 38 is connected to the connecting pipe 36 through a first flange. When the impurities move to the lowest part of the filter screen frame 38, the attached water source flows through the filter screen frame 38 and the bottom frame 34 into the connecting pipe 36 and finally flows into the interior of the second pipeline 4.

One end of the connecting rod 334 slides through the other side of the side plate 35, and one end of the connecting rod 334 is fixedly connected to one side of the connecting plate 332. A limiting groove adapted to the limiting disc 339 is formed on one side of the connecting plate 332. By providing the limiting groove, the limiting disc 339 can move normally inside the connecting plate 332, so that there is a good position limiting measure between the sliding rod 337 and the connecting plate 332. One side of the bottom frame 34 is fixedly connected with a positioning plate 335. One side of the bottom frame 34 is fixedly connected with a second positioning block 336. A sliding rod 337 slides through one side of the connecting plate 332. A spring 338 is sleeved on the outer surface of the sliding rod 337. One end of the spring 338 is welded to one side of the inner wall of the limiting groove, and the other end of the spring 338 is welded to one side of the limiting disc 339. By providing the spring 338, the spring 338 provides sufficient elastic force, and the connecting plate 332 can maintain good position stability by virtue of the elastic force of the spring 338, so that the fixing plate 331 can maintain good position stability by connecting with the connecting plate 332 through the sliding rod 337. The clamping block 3310 stably fixes the top frame 32 and the bottom frame 34. One end of the sliding rod 337 is fixedly connected with a limiting disc 339. One side of the fixing plate 331 is fixedly connected with a clamping block 3310. A first positioning groove adapted to the first positioning block 333 is formed on one side of the filter screen frame 38, and a second positioning groove adapted to the second positioning block 336 is formed on the other side of the filter screen frame 38. By providing the first limiting groove and the second limiting groove, the filter screen frame 38 can be positioned on the bottom frame 34 by means of the first positioning block 333 and the second positioning block 336, so that there is a good positioning measure between the filter screen frame 38 and the bottom frame 34. A third positioning groove adapted to the positioning plate 335 is formed on one side of the top frame 32. By providing the third positioning groove, the positioning plate 335 can be normally inserted into the inside of the top frame 32, so that there is a good positioning measure between the top frame 32 and the bottom frame 34. And clamping holes adapted to the clamping block 3310 are formed on one side of the top frame 32 and one side of the positioning plate 335. By providing the clamping holes, the clamping block 3310 can normally penetrate through the top frame 32 and the positioning plate 335, so that the positioning plate 335 can be fixed inside the top frame 32 by means of the clamping block 3310 after being inserted into the top frame 32, so that a good fixing measure can be maintained between the top frame 32 and the bottom frame 34, and the filter screen frame 38 can be stably fixed between the top frame 32 and the bottom frame 34. A groove adapted to the connecting plate 332 is formed on one side of the side plate 35. By providing the groove, the connecting plate 332 can move normally inside the side plate 35.

The filter screen frame 38 is positioned with the bottom frame 34 by using the first positioning block 333 and the second positioning block 336. After the filter screen frame 38 is placed, the top frame 32 is placed above the filter screen frame 38. The positioning plate 335 is gradually inserted into the interior of the top frame 32. During the process of placing the top frame 32, the fixing plate 331 is pulled to move. During the movement of the fixing plate 331, the clamping block 3310 is driven to move. The clamping block 3310 gradually moves out of the interior of the positioning plate 335 to avoid the clamping block 3310 affecting the normal placement of the top frame 32. During the pulling process of the fixing plate 331, the sliding rod 337 gradually moves out of the interior of the side plate 35 following the movement of the fixing plate 331, and drives the connecting plate 332 to move during the movement. The connecting plate 332 slides on the outer surface of the sliding rod 337. The shape of the spring 338 gradually changes due to the movement of the connecting plate 332 until the fixing plate 331 is pulled until it can no longer be pulled. Continue to place the top frame 32 until the top frame 32 contacts the filter screen frame 38. Release the pulled fixing plate 331. The spring 338 is no longer affected by the acting force, and its shape gradually resumes. During the process of shape resuming, it drives the connecting plate 332 to move.

[0043] Embodiment 3

[0044] Such as Figures 1-6As shown in the figure, the anti - detachment mechanism 37 includes a buckle 371 provided on one side of the filter box 31. Limiting holes adapted to the limiting block 374 are provided on one side of the buckle 371 and one end of the fixed block 375. By providing the limiting holes, the limiting block 374 can normally penetrate through the buckle 371 and insert into the interior of the fixed block 375, enabling the buckle 371 to maintain good position limitation with the help of the limiting block 374. A buckle groove adapted to the buckle 371 is provided on one side of the connecting plate 332. By providing the buckle groove, the top frame 32 and the bottom frame 34 can be fixed on the filter box 31 with the help of the connecting plate 332 and the buckle 371. A connecting groove adapted to the turntable 377 is provided on one side of the buckle 371. By providing the connecting groove, the turntable 377 and the buckle 371 can be normally connected. One side of the connecting plate 332 is movably connected with an adjusting bolt 372 through a first bearing. A fixed disk 373 slidably penetrates through one side of the connecting plate 332. A threaded hole matching the thread on the adjusting bolt 372 is provided on one side of the fixed disk 373. By providing the threaded hole, the fixed disk 373 can adjust its position following the rotation of the adjusting bolt 372. A limiting block 374 is fixedly connected to one side of the fixed disk 373. A fixed block 375 is provided on one side of the buckle 371. A torsion spring 376 is sleeved on the outer surface of the fixed block 375. One side of the fixed block 375 is fixedly connected to a turntable 377. The outer surface of the turntable 377 is movably sleeved on the inner wall of the connecting groove through a second bearing, and one side of the turntable 377 is fixedly connected to one side of the filter box 31. One end of the torsion spring 376 is welded to one side of the inner wall of the connecting groove, and the other end of the torsion spring 376 is welded to one side of the turntable 377. By providing the torsion spring 376, the torsion spring 376 provides sufficient torque, enabling the buckle 371 to actively restore its position with the torque of the torsion spring 376 after rotating and swinging.

[0045] In this embodiment, during installation, after the filter screen frame 38 is positioned and fixed, the top frame 32 and the bottom frame 34 with the filter screen frame 38 fixed are inserted into the filter box 31, and the fixing plate 331 is slowly pushed to move. During the pushing process, the swinging buckle 371 rotates on the filter box 31. During the swinging process of the buckle 371, it gradually rotates on the outer surface of the turntable 377. Affected by the acting force of the rotation of the buckle 371, the shape of the torsion spring 376 gradually changes until the swinging buckle 371 rotates to a certain extent and then keeps the swinging position of the buckle 371 stationary. Continue to push the fixing plate 331 until the fixing plate 331 cannot be pushed any further. The filter screen frame 38 completely moves into the filter box 31. The bottom of the bottom frame 34 and the connecting pipe 36 are connected by a first flange and bolts. Keep the position of the fixing plate 331 after being pushed stationary, release the buckle 371 that keeps the rotation position stationary, and the torsion spring 376 is no longer affected by the acting force. Its shape gradually recovers, and during the process of shape recovery, it drives the position of the buckle 371 to recover. When the buckle 371 recovers its position, it gradually approaches the connecting plate 332 and buckles and fixes the connecting plate 332. After the buckle 371 contacts and buckles with the connecting plate 332, rotate the adjusting bolt 372. As the adjusting bolt 372 rotates, the fixed disk 373 gradually moves, and during the moving process, it drives the limiting block 374 to move. The limiting block 374 gradually penetrates through the buckle 371 and inserts into the fixed block 375 to limit the position of the buckle 371, so that the buckle 371 and the connecting plate 332 are stably buckled and fixed to each other.

A pipe fitting 54 slides through one side of the connecting seat 51. One end of the pipe fitting 54 is communicated with the output end of the water pump body 1 through a second flange. A fourth positioning groove adapted to the third positioning block 55 is formed on one side of the connecting seat 51. By forming the fourth positioning groove, the pipe fitting 54 and the connecting seat 51 can be positioned with the help of the third positioning block 55 during the connection process, avoiding the phenomenon that the pipe fitting 54 cannot be normally connected. And a thread groove matching the thread on the thread ring 53 is formed on one side of the connecting seat 51. By forming the thread groove, the pipe fitting 54 and the connecting seat 51 can be threadedly connected, so that there is a good and stable connection measure between the water pump body 1 and the second pipe 4.

The pipe fitting 54 is gradually inserted into the inside of the connecting seat 51. When the pipe fitting 54 cannot be moved further after insertion, the push collar 52 is pushed towards the connecting seat 51. When the push collar 52 is pushed until the thread ring 53 contacts the connecting seat 51, the collar 52 is rotated, so that the thread ring 53 is threadedly connected to the connecting seat 51, and the rotation of the collar 52 continues until it cannot be rotated any further. The connection between the pipe fitting 54 and the connecting seat 51 is then completed.

The other end of the pipe fitting 54 is positioned with the connecting seat 51 on the second pipe 4 by using the third positioning block 55. The pipe fitting 54 is gradually inserted into the inside of the connecting seat 51. When the pipe fitting 54 cannot move further after being inserted, the push collar 52 is pushed towards the connecting seat 51. When the push collar 52 reaches the contact with the thread ring 53 and the connecting seat 51, the collar 52 is rotated, so that the thread ring 53 is threadedly connected to the connecting seat 51 until the collar 52 cannot be rotated any further. The connection between the pipe fitting 54 and the connecting seat 51 is completed. The filter screen frame 38 is placed on the bottom frame 34. The filter screen frame 38 is positioned with the bottom frame 34 by using the first positioning block 333 and the second positioning block 336. After the filter screen frame 38 is placed, the top frame 32 is placed above the filter screen frame 38. The positioning plate 335 is gradually inserted into the inside of the top frame 32. During the process of placing the top frame 32, the fixing plate 331 is pulled to move. During the movement of the fixing plate 331, the clamping block 3310 is driven to move. The clamping block 3310 gradually moves out of the inside of the positioning plate 335 to avoid the clamping block 3310 affecting the normal placement of the top frame 32. During the pulling process of the fixing plate 331, the sliding rod 337 gradually moves out of the inside of the side plate 35 following the movement of the fixing plate 331 and drives the connecting plate 332 to move during the movement. The connecting plate 332 slides on the outer surface of the sliding rod 337. The shape of the spring 338 gradually changes due to the movement of the connecting plate 332 until the fixing plate 331 cannot be pulled any further. Continue to place the top frame 32 until the top frame 32 contacts the filter screen frame 38. Release the pulled fixing plate 331. The spring 338 is no longer affected by the acting force, and its shape gradually resumes. During the process of shape resuming, the connecting plate 332 is driven to move. The fixing plate 331 gradually resumes its position following the resuming of the connecting plate 332 by means of the connecting rod 334 and drives the clamping block 3310 to gradually insert into the inside of the top frame 32 and insert into the inside of the positioning plate 335 after inserting into the inside of the top frame 32 to fix the top frame 32 and the bottom frame 34, so that the filter screen frame 38 is stably fixed between the top frame 32 and the bottom frame 34. The top frame 32 and the bottom frame 34 with the filter screen frame 38 fixed are inserted into the filter box 31, and the fixing plate 331 is slowly pushed to move. During the pushing process, the swinging buckle 371 rotates on the filter box 31. During the swinging process of the buckle 371, it gradually rotates on the outer surface of the turntable 377. The torsion spring 376 is affected by the acting force of the rotation of the buckle 371, and its shape gradually changes until the swinging buckle 371 rotates to a certain extent and then keeps the position of the swinging of the buckle 371 unchanged. Continue to push the fixing plate 331 until the fixing plate 331 cannot be pushed any further. The filter screen frame 38 completely moves into the inside of the filter box 31. The bottom of the bottom frame 34 and the connecting pipe 36 are connected by using the first flange and bolts. Keep the position of the fixing plate 331 after being pushed unchanged. Release the buckle 371 that keeps the rotating position unchanged. The torsion spring 376 is no longer affected by the acting force,Its shape gradually resumes, and during the process of shape resumption, it drives the position of the buckle block 371 to resume. When the position of the buckle block 371 resumes, it gradually approaches the connecting plate 332 and buckles and fixes the connecting plate 332. After the buckle block 371 contacts and buckles with the connecting plate 332, the adjusting bolt 372 is rotated. As the adjusting bolt 372 rotates, the fixed disk 373 gradually moves, and during the movement, it drives the limiting block 374 to move. The limiting block 374 gradually penetrates through the buckle block 371 and inserts into the inside of the fixed block 375 to limit the position of the buckle block 371, so that the buckle block 371 and the connecting plate 332 are stably buckled and fixed;

[0051] When in use, when the water pump body 1 works, water flows into the inside of the filter tank 31 from the first pipe 2. The water flow contacts the filter mesh frame 38 inside the filter tank 31. The filter mesh frame 38 is a corrugated filter mesh. When the water flow contacts the filter mesh frame 38, the impurities in the water flow are filtered through the filter mesh frame 38. The water flow after impurity filtration flows through the filter mesh frame 38 and into the inside of the second pipe 4, while the impurities filtered by the filter mesh frame 38 remain on the filter mesh frame 38. When the filter mesh frame 38 filters the impurities in the water flow, the larger impurities will gradually move towards the lower part of the filter mesh frame 38 due to the shape of the filter mesh frame 38 and the slight vibration generated when the filter mesh frame 38 is impacted by the water flow until the impurities move to the lowest part of the filter mesh frame 38 and remain at the lowest part. The bottom frame 34 at the corresponding position at the lowest part of the filter mesh frame 38 is connected to the connecting pipe 36 through the first flange. When the impurities move to the lowest part of the filter mesh frame 38, the attached water source flows through the filter mesh frame 38 and the bottom frame 34 into the connecting pipe 36 and finally into the inside of the second pipe 4.
