[0027] The effect achieved by the entire embodiment 1 is as follows: when the sensor 14 enters the input tube 12, the operator puts the two top covers 16 on the outer wall of the cable 13, and then the bottom of the top cover 16 is attached to the top of the input tube 12. At this time, the insert plate 28 enters the slot 22 and contacts the inclined surface of the card block 25. The insert plate 28 pushes the card block 25 to move, and the spring 24 is compressed. When the card slot 29 moves to the side of the card block 25, the card block 25 enters the card slot 29 under the elastic force of the spring 24. At this time, the top cover 16 is fixed, and the top cover 16 can prevent dust from entering the input tube 12.

[0028] Example 2, as Figures 1-5 As shown, a fixing seat 18 is fixedly installed on the top of the top cover 16. A storage groove 30 is opened on the top of the fixing seat 18. A fixing groove 32 is opened on the inner wall of the storage groove 30. A threaded hole 33 is opened through the inner wall of the fixing groove 32.

[0033] Furthermore, a display screen 5 is provided on the outer wall of the main body 4, and multiple evenly distributed buttons 6 are provided on the outer wall of the main body 4. The display screen 5 is used to observe the values ​​detected by the sensor 14.

[0034] Furthermore, the outer wall of the insert plate 28 fits against the inner wall of the slot 22, and the outer wall of the card block 25 fits against the inner wall of the card groove 29. When the card block 25 enters the card groove 29, the insert plate 28 can be fixed in place.

[0035] Furthermore, the outer wall of the connecting plate 19 is in contact with the inner wall of the storage groove 30, and the outer wall of the connecting block 36 is in contact with the inner wall of the connecting groove 31. When the connecting block 36 enters the connecting groove 31, the connecting plate 19 can be fixed in place.

[0036] Furthermore, the inner walls of both cleaning pads 21 are in contact with the outer wall of the cable 13, so that when the cable 13 moves, the two cleaning pads 21 can scrape away the dust on the surface of the cable 13.

[0037] The overall effect of Embodiment 2 is that when the top cover 16 is fixed, the operator continues to convey the cable 13 downwards. When the outer wall of the cable 13 comes into contact with the cleaning pad 21, the cleaning pad 21 can scrape off the dust on the outer wall of the cable 13, preventing the dust from entering the tank 1. When it is necessary to clean or replace the cleaning pad 21, the operator rotates the handle 35, which drives the threaded rod 34 to rotate. The threaded rod 34 moves along the threaded hole 33, and the connecting block 36 leaves the connecting groove 31. In this way, the operator can pull out the connecting plate 19, clean or replace the cleaning pad 21, reset the connecting plate 19, and rotate the handle 35 in the opposite direction. The connecting block 36 enters the connecting groove 31, thus completing the replacement and improving the replacement efficiency.

[0038] Working principle: During use, the operator fixes the base plate 2 to the top of the tank 1 by passing bolts through the fixing hole 3, passes the cable 13 through the fixed pulley 11, and starts the electric telescopic rod 9. The telescopic end of the electric telescopic rod 9 extends, moving the sensor 14 to the center position of the input tube 12. The motor 15 is started, the roller 8 rotates, the cable 13 leaves the roller 8, and the sensor 14 enters the water vertically, improving the measurement accuracy and reducing the friction of the cable 13. When the sensor 14 enters the input tube 12, the operator puts the two top covers 16 on the outer wall of the cable 13, and then fits the bottom of the top cover 16 against the top of the input tube 12. At this time, the insert plate 28 enters the slot 22 and contacts the inclined surface of the locking block 25. The insert plate 28 pushes the locking block 25 to move, and the spring 24 is compressed. When the locking groove 29 moves next to the locking block 25, the locking block 25 enters the locking groove 29 under the elastic force of the spring 24. At this time, the top cover 16 is fixed, which can prevent dust from entering the input tube 12. When the top cover 16 is fixed, the operator continues to feed the cable 13 downwards. When the outer wall of the cable 13 contacts the cleaning pad 21, the cleaning pad 21 can scrape away the dust on the outer wall of the cable 13, preventing dust from entering the tank 1. When it is necessary to clean or replace the cleaning pad 21, the operator rotates the handle 35, which drives the threaded rod 34 to rotate. The threaded rod 34 moves along the threaded hole 33, causing the connecting block 36 to leave the connecting groove 31. In this way, the operator can pull out the connecting plate 19, clean or replace the cleaning pad 21, reset the connecting plate 19, and rotate the handle 35 in the opposite direction. The connecting block 36 enters the connecting groove 31, thus completing the replacement and improving the replacement efficiency. When the use is over, the operator pulls the two pull plates 27. The pull plates 27 drive the locking block 25 away from the locking groove 29 through the connecting rod 26, at which point the top cover 16 can be removed.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
