[0035] The following is combined with Figure 1-Figure 8 This application is described in further detail.

[0036] The embodiment of the present application discloses a water level monitoring device dedicated to a manhole.

[0037] Embodiment 1:

[0038] Reference Figure 1 A special water level monitoring device for a manhole includes a mounting plate 1, a support seat 2, a flip positioning mechanism 3, a first mounting seat 4, a radar water level gauge 5, a mounting frame 11 and a battery assembly 6. The mounting plate 1 is fixedly mounted on the well wall near the wellhead by bolts, and the support seat 2 is fixedly mounted on the mounting plate 1 by bolts, and the middle part of the support seat 2 protrudes away from the mounting plate 1.

[0039] The flip positioning mechanism 3 is mounted on the side wall of the support seat 2, the first mounting seat 4 is mounted on the flip positioning mechanism 3, and the radar water level meter 5 is mounted on the first mounting seat 4. The mounting frame 11 is fixedly mounted on the well wall near the wellhead by bolts, the battery assembly 6 is fixedly mounted on the mounting frame 11, and the battery assembly 6 is electrically connected to the radar water level meter 5.

[0040] Reference Figure 2 and Figure 3The first mounting seat 4 includes an adjustment plate 41, an adjustment bolt 42, a first clamp joint 43, a second clamp joint 44 and a quick-connect clamp 45. The adjustment plate 41 is L-shaped and fixedly mounted on the flip end of the flip positioning mechanism 3. The first clamp joint 43 is fixedly mounted on the side wall of the adjustment plate 41 away from the support seat 2 in the horizontal direction. The second clamp joint 44 is coaxially mounted on the end of the first clamp joint 43 away from the adjustment plate 41. The radar water level meter 5 is fixedly mounted on the end of the second clamp joint 44 away from the first clamp joint 43. The quick-connect clamp 45 is sleeved at the connection between the first clamp joint 43 and the second clamp joint 44 and fixes the first clamp joint 43 and the second clamp joint 44. Rotating the first clamp joint 43 can level the radar water level meter 5 with the horizontal direction as the rotation axis. After the radar water level meter 5 is leveled, the clamp joint is locked to lock the position of the radar water level meter 5.

[0041] The first nut 25 is fixedly mounted on the adjustment plate 41, and the adjustment bolt 42 is threaded through the first nut 25 and penetrates the adjustment plate 41. The second nut 26 is fixedly mounted on the end of the adjustment bolt 42 close to the support seat 2, and the second nut 26 abuts against the side wall of the support seat 2 away from the mounting plate 1. When the adjustment nut is rotated, the adjustment nut drives the adjustment plate 41 to move slightly through the first nut 25, and the adjustment plate 41 rotates slightly on the support seat 2 under the action of the flip positioning mechanism 3. The adjustment plate 41 then drives the radar water level gauge 5 to rotate slightly through the first clamp joint 43 and the second clamp joint 44, so that the radar water level gauge 5 can be leveled in multiple directions.

[0042] The flip positioning mechanism 3 includes a hinge 301, a lifting ear 302 and a pin 303. The fixed end of the hinge 301 is fixedly connected to the side wall of the support seat 2, the rotating end of the hinge 301 is fixedly connected to the adjustment plate 41, the lifting ear 302 is fixedly installed on the top wall of the first clamp joint 43, and the pin 303 is detachably plugged into the top wall of the support seat 2.

[0043] When construction workers need to go down the well to work, they first pull out the pin 303 from the support seat 2, and then flip the first mounting seat 4 upward. When the first mounting seat 4 rotates upward to a vertical state, the first mounting seat 4 drives the lifting ear 302 to move to the top of the support seat 2. At this time, the pin 303 passes through the lifting ear 302 and is reinserted into the support seat 2. The pin 303 limits the first mounting seat 4 through the lifting ear 302, so that the first mounting seat 4 remains in a vertical state, thereby facilitating construction workers to go down the well to work.

[0044] Reference Figure 1The bottom of the support seat 2 is fixedly mounted with a second mounting seat 8 by bolts, and an extension rod 9 is clamped and fixedly mounted in the second mounting seat 8, and the bottom end of the extension rod 9 extends downward from the second mounting seat 8. A third mounting seat 10 is fixedly mounted at the bottom end of the extension rod 9, and a static pressure water level gauge 12 is fixedly mounted in the third mounting seat 10, and the static pressure water level gauge 12 is electrically connected to the battery assembly 6. A signal transmission assembly 13 is fixedly mounted on the mounting frame 11, and the signal transmission assembly 13 is electrically connected to the radar water level gauge 5 and the static pressure water level gauge 12.

[0045] When the water level exceeds the radar water level meter 5, the radar water level meter 5 cannot measure the water level, and the static pressure water level meter 12 can work normally and measure the water level. At the same time, the signal transmission component 13 transmits the collected water level data to the user data center via 4G signals, thereby saving electricity.

[0046] The implementation principle of a special water level monitoring device for a manhole in Example 1 of the present application is as follows: first, pull out the pin 303 from the support seat 2, and then flip the first mounting seat 4 upward. When the first mounting seat 4 rotates upward to a vertical state, the first mounting seat 4 drives the lifting ear 302 to move to the top of the support seat 2. At this time, the pin 303 is passed through the lifting ear 302 and reinserted into the support seat 2. The pin 303 limits the first mounting seat 4 through the lifting ear 302, so that the first mounting seat 4 remains in a vertical state, thereby facilitating construction personnel to go down the well to work.

[0050] The locking block 315 is fixedly mounted on the top wall of the first clamp connector 43. A locking groove 14 is provided in the middle of the top wall of the locking block 315. Two clamping blocks 316 are slidably mounted in the locking block 315. Two second elastic members 318 are mounted in the locking block 315 and abut against the ends of the two clamping blocks 316 that are away from each other. In the present application, the second elastic members 318 can be selected as springs. The two second elastic members 318 push the two clamping blocks 316 to move toward each other.

When the first mounting seat 4 is rotated to a vertical state, the first mounting seat 4 drives the two clamping blocks 316 to move toward the blocking column 314 through the locking block 315. The two chamfers 15 of the clamping blocks 316 first contact the blocking column 314, and the blocking column 314 can push the two clamping blocks 316 to move away from each other, so that the blocking column 314 can enter the locking groove 14, and the second elastic member 318 then pushes the clamping blocks 316 to move and reset, so that the flipped first mounting seat 4 can be limited.

In the present application, the first elastic member 317 can be selected as a torsion spring, and the third elastic member 319 can be selected as a tension spring.

[0053] When the first mounting seat 4 needs to be flipped downward, the rotating sleeve 313 is rotated, and the rotating sleeve 313 drives the blocking column 314 to move downward through the transmission assembly 320. After the top of the blocking column 314 moves downward out of the locking groove 14, the first mounting seat 4 can be released from the position limit. At this time, the first mounting seat 4 can be driven to flip downward by the rotating sleeve 313, the first pull rod 311 and the second pull rod 312. During the downward flipping of the first mounting seat 4, the first elastic member 317 can drive the rotating sleeve 313 to rotate and reset, and the third elastic member 319 can drive the blocking column 314 to move upward and reset, so as to facilitate the first mounting seat 4 that is flipped upward to be limited again.

[0058] A first curved plate 23 is fixedly mounted on the end wall of the second rotating shaft 323 close to the third rotating shaft 325 along its own circumferential direction, the curvature of the curved surface of the first curved plate 23 is 45°, and an inclined surface is formed at the end of the first curved plate 23. Second curved plates 24 are fixedly mounted on the side walls away from each other of the two second connecting plates 27 through connecting blocks, and the side walls of the two second curved plates 24 close to each other abut against the two end walls of the third rotating shaft 325, the curvature of the curved surface of the second curved plate 24 is 45°, and an inclined surface is formed at the end of the second curved plate 24.

[0059] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 When the first mounting seat 4 is in a horizontal state, the first curved plate 23 abuts against the second curved plate 24, so that the plug-in block 20 is not inserted into the slot 21. When the first mounting seat 4 is flipped upward by 45°, the second rotating shaft 323 drives the first curved plate 23 to rotate forward by 45° so that the first curved plate 23 is separated from the second curved plate 24. At this time, the fourth elastic member 22 pushes the second rotating shaft 323 to slide toward the direction close to the third rotating shaft 325, and the second rotating shaft 323 drives the plug-in block 20 to move and abut against the end wall of the third rotating shaft 325. When the first mounting seat 4 is flipped upward by 45°, the second rotating shaft 323 drives the first curved plate 23 to rotate forward by 90°, and the fourth elastic member 22 pushes the plug-in block 20 to be inserted into the slot 21 through the second rotating shaft 323, thereby connecting the second rotating shaft 323 and the third rotating shaft 325, and the first mounting seat 4 is locked.

[0060] When the first mounting seat 4 needs to be unlocked, the rotating sleeve 313 is rotated, and the rotating sleeve 313 drives the first rotating shaft 322 to rotate through the connecting rod 321. A rotating groove 30 is provided in the second pull rod 312, and the connecting rod 321 is located in the rotating groove 30. The rotating groove 30 limits the rotation of the connecting rod 321, so that the maximum rotation angle of the connecting rod 321 is 30°. The first rotating shaft 322 drives the second rotating shaft 323 to rotate 30° in the opposite direction through the first synchronous belt 324. The second rotating shaft 323 drives the third rotating shaft 325 to rotate through the plug block 20, and the third rotating shaft 325 drives the fourth rotating shaft 326 to rotate through the second synchronous belt 327. The fourth rotating shaft 326 drives the driving rack 329 to move downward through the driving gear 328, and the driving rack 329 drives the blocking column 314 to move down and out of the locking groove 14, so that the first mounting seat 4 can be unlocked.

[0061] The first mounting seat 4 is flipped downward again. When the first mounting seat 4 is flipped downward by 15°, the second rotating shaft 323 drives the first curved plate 23 to rotate in the opposite direction by 15°. At this time, the inclined surface of the first curved plate 23 abuts against the inclined surface of the second curved plate 24. When the first mounting seat 4 continues to flip downward, the first curved plate 23 abuts against the second curved plate 24 again, and then the second rotating shaft 323 is pushed by the first curved plate 23 to move away from the third rotating shaft 325. The second rotating shaft 323 drives the plug 20 to slide out of the slot 21, and the third elastic member 319 can pull the blocking column 314 to rise and reset by driving the rack 329. Then release the rotating sleeve 313, and the first elastic member 317 can drive the rotating sleeve 313 to rotate and reset.

[0062] The implementation principle of the second embodiment of the present application is as follows: when the first mounting seat 4 needs to be flipped upward, the second pull rod 312 is pulled and rotated by the handle 29, and the second pull rod 312 drives the first pull rod 311 to rotate and can drive the first mounting seat 4 to flip upward. When the first mounting seat 4 is rotated to a vertical state, the first mounting seat 4 drives the two clamping blocks 316 to move toward the blocking column 314 through the locking block 315, and the two chamfers 15 of the clamping blocks 316 first contact the blocking column 314, and the blocking column 314 can push the two clamping blocks 316 to move away from each other, so that the blocking column 314 can enter the locking groove 14, and the second elastic member 318 then pushes the clamping blocks 316 to move and reset, so that the flipped first mounting seat 4 can be limited. When the first mounting seat 4 needs to be flipped downward, the rotating sleeve 313 is rotated, and the rotating sleeve 313 drives the blocking column 314 to move downward through the transmission assembly 320. After the top of the blocking column 314 moves downward out of the locking groove 14, the first mounting seat 4 can be released from the position limit. At this time, the first mounting seat 4 can be driven to flip downward by the rotating sleeve 313, the first pull rod 311 and the second pull rod 312. During the downward flipping of the first mounting seat 4, the first elastic member 317 can drive the rotating sleeve 313 to rotate and reset, and the third elastic member 319 can drive the blocking column 314 to move upward and reset, so as to facilitate the first mounting seat 4 that is flipped upward to be limited again.

For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
