[0056] In this embodiment, both ends of the transmission seat 11 are slidably connected to linear guide rods, and one end of the linear guide rod is also fixedly connected to the push plate 14. Through the provision of the linear guide rod, the displacement of the push plate 14 can be effectively guided to prevent the push plate 14 from rotating with the hollow shaft 12, thereby greatly ensuring the stability of the displacement of the push plate 14.

[0057] In more detail, through holes are provided at both ends of the transmission seat 11, and two linear guide rods are respectively assembled in the two through holes, and alloy balls are also provided in the through holes to improve the smoothness of the linear guide rods when sliding;

[0058] In this embodiment, the top of the transmission seat 11 and the bottom of the stabilizing groove 23 are fixedly connected with an anti-skid pad, and the anti-skid pad is provided with an anti-skid pattern. When the stabilizing groove 23 contacts the top of the transmission seat 11, the friction force of the rotation of the transmission shaft 17 can be increased, thereby preventing the transmission shaft 17 from rotating uncontrollably.

[0060] Two positioning ears 25, both positioning ears 25 are fixedly connected to the position corresponding to the notch 3 on one side of the detection tube 1, a positioning shaft 26 is rotatably connected between the two positioning ears 25, the outer side of the positioning shaft 26 is fixedly connected to a carrying arc plate 27, and the inner side of the carrying arc plate 27 is fixedly connected to a filter screen 28;

Due to the provision of the sealing strip, when the mounting arc plate 27 is located at the bottom end of the detection tube 1, the filter screen 28 is moved into the detection tube 1, and at the same time, the sealing strip is moved into the sealing groove, thereby sealing the connection between the mounting arc plate 27 and the detection tube 1, preventing the fluid from flowing out of the gap between the mounting arc plate 27 and the detection tube 1.

The locking holes 33 are arc-shaped, and the locking plate 31 is snap-connected to the inside of the locking holes 33. Due to the arrangement of the locking holes 33, when the rotating shaft 30 drives the locking plate 31 to rotate, the locking plate 31 can be driven to gradually screw into the locking holes 33, thereby effectively positioning the locking screw 37.

[0064] In this embodiment, the limiting member includes:

[0065] A stop plate 34 is fixedly connected to one end of the positioning seat 29. A stop groove 35 is formed at one end of the stop plate 34.

The locking screw 37 is also located inside the stop groove 35. A stop block 38 is threadedly connected to the outer side of the locking screw 37.

[0066] Example 2:

[0067] See also Figure 1-8 This embodiment provides a technical solution based on the first embodiment: the drainage component 9 includes:

[0068] Drainage tube 39, the two ends of the drainage tube 39 are respectively fixedly connected to the two drainage holes 8, and the two ends of the supporting plate 10 are respectively fixedly connected to the two ends of the drainage tube 39, and the two ends of the bottom of the supporting plate 10 are fixedly connected to the support frame 40, and the bottom end of the support frame 40 is laterally rotatably connected to the drainage shaft 41, and the end of the drainage shaft 41 located inside the drainage tube 39 is fixedly connected to the drainage piece 42;

[0069] Two linkage shafts 43 are vertically rotatably connected to the two ends of the carrier plate 10. The top ends of the two linkage shafts 43 are fixedly connected to transmission spur gears B44, and the two transmission spur gears B44 are respectively meshed with the two transmission racks 15. The bottom ends of the two linkage shafts 43 are fixedly connected to transmission worms 45. The end of the drainage shaft 41 located outside the drainage tube 39 is fixedly connected to a matching worm gear 46, and the matching worm gear 46 is meshed with the transmission worm gear 45.

[0070] In this embodiment, a support hole is formed at the bottom end of the support frame 40, and the drainage shaft 41 is connected to the inside of the support hole through a ball bearing. The provision of the support hole enables effective assembly of the drainage shaft 41, and the provision of the ball bearing ensures smooth rotation of the drainage shaft 41.

[0071] In summary, the outer sides of the flow control plate 6 and the guide plate 42 are fixedly connected with sealing rings, and the material of the sealing rings can be rubber.

[0072] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0073] Working principle: First, the end of the detection tube 1 close to the flow meter 2 is fixedly connected to the input end of the water pump, so that the fluid enters the water pump through the detection tube 1. In conjunction with the setting of the flow meter 2, the flow data of the fluid in the detection tube 1 can be detected in real time for personnel to view;

[0074] When the flow rate is too high, first pull the displacement rod 20 upwards, prompting the stabilizing plate 21 to drive the stabilizing plate 24 to separate from the transmission seat 11, and then rotate the displacement rod 20. Since the stabilizing plate 24 is connected to the inside of the stabilizing groove 23, the transmission shaft 17 rotates accordingly, and with the help of the transmission bevel gear 18, the matching bevel gear 19 is driven to rotate, thereby driving the hollow shaft 12 to rotate. Under the connection between the hollow shaft 12 and the transmission screw 13, the transmission screw 13 can be linearly displaced to push the push plate 14 to approach the central shaft 5. The transmission rack 15 shifts the transmission spur gear A16, and then the central shaft 5 drives the flow control plate 6 to rotate, and adjusts the gap between the flow control plate 6 and the detection tube 1, so as to control the flow rate of the fluid in the detection tube 1. After adjustment, the displacement rod 20 is released. When the stabilizing plate 21 is displaced, it can squeeze the coil spring 22. When the displacement rod 20 is released, the coil spring 22 can rebound, so that the stabilizing plate 24 and the transmission seat 11 are closely fitted together, thereby increasing the friction force of the rotation of the transmission shaft 17.

[0075] Before the fluid reaches the water pump, solid impurities in the fluid can be filtered through the filter 28 to prevent solid impurities from entering the water pump. When the filtering effect of the filter 28 is poor, the transmission shaft 17 is first rotated to cause the hollow shaft 12 to drive the transmission screw 13 to move in the direction close to the linkage shaft 43. When the transmission rack 15 passes through the linkage shaft 43, the transmission rack 15 can synchronously shift the transmission spur gear A16 and the transmission spur gear B44. Since the transmission spur gear B44 is supported by the linkage shaft 43, it can The power of the transmission spur gear B44 is transmitted to the transmission worm 45 via the linkage shaft 43, prompting the transmission worm 45 to turn the matching worm gear 46. This, in turn, drives the drainage plate 42 to rotate with the help of the drainage shaft 41. When the flow control plate 6 completely blocks the detection tube 1, the drainage plate 42 will release the blockage of the drainage tube 39. After the fluid in the detection tube 1 contacts one of the flow control plates 6, it is blocked by one of the flow control plates 6 and enters from one end of the drainage tube 39. It then returns to the detection tube 1 through the other end of the drainage tube 39.

[0076] After the flow control plate 6 blocks the detection tube 1, no fluid will pass between the two flow control plates 6, and then the stop block 38 is rotated to move the stop block 38 away from the stop plate 34 along the locking screw 37, so as to reduce the friction force of the rotation of the eccentric plate 36, and then the eccentric plate 36 is pulled. Since the eccentric plate 36 is supported by the rotating shaft 30, the locking plate 31 can be driven to rotate through the rotating shaft 30. When the locking plate 31 moves out of the locking hole 33, the carrying arc plate 27 can be unlocked, and then the carrying arc plate 27 is pulled to make it flip over under the support of the positioning shaft 26 to move the filter screen 28 out of the gap 3, and then it can be cleaned.
