All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 7 The present invention provides a technical solution: a manhole cover monitoring device applied to an intelligent manhole cover monitoring system, comprising a manhole cover 4 connected to a near wellhead 3, the manhole cover monitoring device applied to the intelligent manhole cover monitoring system comprises: a card rod 14, the card rod 14 can not only fix the sensor 15, but also support the manhole cover 4 to improve the overall strength, the lower end near the wellhead 3 is fixedly connected with a fixing plate 2, the surface of the fixing plate 2 is provided with a through groove, so as to improve the stability of the entire device during installation, a plurality of reinforcing plates 1 are fixedly connected to the side surface near the wellhead 3, the reinforcing plates 1 are welded to the fixing plates 2, and the supporting strength of the near wellhead 3 can be improved by the reinforcing plates 1, one end of the arc surface of the manhole cover 4 is fixedly connected with a swivel seat 13, and the upper side of the other end is fixedly connected with a handle 8, which facilitates the flipping operation of the manhole cover 4, and a locking block 11 is fixedly connected to the lower side, and the swivel seat 13 is rotatably connected to the near wellhead 3. At this time, the manhole cover 4 can be rotated with the swivel seat 13 as the center through the handle 8, thereby opening the manhole cover 4.

[0027] When the device is installed as a whole, the overall strength can be improved by the fixed plate 2 and the wellhead 3 located below the ground, and the reversible manhole cover 4 facilitates the inspection and maintenance of the device itself and the sewer.

[0028] The upper end of the manhole cover 4 is fixedly connected to a solar panel 6, and the lower end of the solar panel 6 is fixedly connected to a connecting column 7. The internal device can be charged through the solar panel 6. The lower end of the connecting column 7 passes through the manhole cover 4 and is plugged into the sensor 15. The lower end of the manhole cover 4 is fixedly connected to a number of locking blocks 11, and the position of the manhole cover 4 can be locked by the locking blocks 11. The manhole cover 4 is in close contact with the inner wall near the wellhead 3. One end of the guide rod 16 is plugged into the inner wall near the wellhead 3. When the manhole cover 4 is opened, it can be removed by lifting the guide rod 16. The other end of the guide rod 16 is fixedly connected to the sensor 15. At this time, the position of the sensor 15 is fixed. A slide groove 26 is provided on the surface of the guide rod 16. The inner wall of the sensor 15 is fixedly connected to Spring 17, the spring 17 is used to facilitate the detection of the offset of the manhole cover 4. The other end of the spring 17 is fixedly connected to the clamp 18, and the spring 17 is in a compressed state. At this time, when the clamp 18 moves in the horizontal direction, the spring 17 will change the amount of compression accordingly. The clamp 18 is fixedly connected to the guide rod 16, and the movement of the clamp 18 can be guided by the guide rod 16. At the same time, the spring 17 is sleeved on the surface of the guide rod 16 to prevent the spring 17 from bending. The other end of the guide rod 16 passes through the sensor 15 and is slidably connected to the card rod 14. The middle position of the lower end of the manhole cover 4 is fixedly connected to a fixed ball 19. The surface of the fixed ball 19 is in close contact with the clamp 18. At this time, when the manhole cover 4 deviates, the fixed ball 19 will also move accordingly.

[0029] During installation, the clamp 18 will clamp the position of the fixed ball 19 and take the current position of the fixed ball 19 as the origin. When the manhole cover 4 deviates during operation, the fixed ball 19 will move together with the manhole cover 4. At this time, the pressure of the fixed ball 19 on the clamp 18 at different positions will change. At this time, the sensor 15 can monitor the position of the manhole cover 4 by monitoring the changes in the elastic force of the spring 17 at different positions.

[0030] The sensor 15 is electrically connected to the solar panel 6 through the connecting column 7. The lower end of the sensor 15 is fixedly connected to the motor 20. The motor 20 is electrically connected to the solar panel 6. The sensor 15 and the motor 20 can be charged and powered by the solar panel 6. The output end of the motor 20 is fixedly connected to the threaded rod 22. When the motor 20 is started, the threaded rod 22 will rotate accordingly. The surface of the threaded rod 22 is threadedly connected to the sliding block 23. When the threaded rod 22 rotates, the sliding block 23 changes state under the action of the thread. The four sides of the sliding block 23 are rotatably connected to the transmission plate 24. The other end of the transmission plate 24 is rotatably connected to the slide 25. Through the rotation of the transmission plate 24 The position of the slide 25 can be changed. The two ends of the slide 25 are fixedly connected with the insertion rod 21, and the middle position of the slide 25 is fixedly connected with the fixing column 12. When the slide 25 moves, the fixing column 12 and the insertion rod 21 will move accordingly, and the slide 25 is slidably connected with the slide groove 26. The slide 25 is flat to prevent it from rotating in the slide groove 26. Each insertion rod 21 is plugged into a locking block 11. At this time, the position of the locking block 11 is fixed, thereby fixing the position of the manhole cover 4. The end of the fixing column 12 away from the slide groove 26 passes through the card rod 14 and is plugged into the inner wall near the wellhead 3. The connection stability of the card rod 14 in the working state is further improved through the fixing column 12.

[0031] When the manhole cover 4 is closed, the motor 20 is started, and the sliding block 23 moves vertically up and down along the threaded rod 22 through the rotation of the threaded rod 22. When the sliding block 23 moves, the transmission plate 24 starts to rotate, thereby forcing the slide 25 to slide along the slide groove 26. At this time, the fixed column 12 will be inserted into the inner wall near the wellhead 3, and the insertion rod 21 will be plugged into the locking block 11, and the position of the manhole cover 4 will be fixed.

[0032] A number of diversion holes 5 are provided on the surface of the manhole cover 4, through which the surface water on the road can be drained. The lower end of the manhole cover 4 contacts the upper side of the clamping rod 14, and the diameter of the manhole cover 4 is equal to the diameter of the inner wall near the wellhead 3, so as to reduce the deformation and displacement of the manhole cover 4 after being under pressure for a long time. The upper end near the wellhead 3 is slidably connected to a latch 10, and one end of the latch 10 is rotatably connected to a pull rod 9, which can drive the latch 10 to slide through the pull rod 9, and the other end of the latch 10 passes through a locking block 11 and is plugged into it. At this time, the manhole cover 4 can be fixed by the swivel seat 13 and the latch 10, and the length of the slide groove 26 is greater than the depth of the fixing column 12 inserted into the inner wall near the wellhead 3, so that the integral clamping rod 14 and the manhole cover 4 can be disassembled and installed normally.

[0033] The manhole cover 4 can be fixed for a second time by the latch 10 . When the solar panel 6 is underpowered for a long time, the manhole cover 4 can be fixed and removed manually by the latch 10 .

[0034] When the device is working, when it is necessary to open the manhole cover 4, the motor 20 is started to move the sliding block 23 downward. At this time, the fixed column 12 gradually disengages from the near wellhead 3 and the insertion rod 21 gradually disengages from the locking block 11. Then, the latch 10 is pulled by the pull rod 9, and the manhole cover 4 can be rotated. After the manhole cover 4 is installed, the sensor 15 can monitor the position of the manhole cover 4 in real time. The deformation and elastic force changes brought to the spring 17 by the fixed ball 19 can detect the deviation trajectory of the manhole cover 4, so that it is convenient to promptly remind the staff to go and deal with it when excessive deviation occurs.

[0035] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
