The existing wellpoint dewatering detection equipment for foundation pit excavation is integrated and cannot adapt to wells of different depths.
[0003] The prior art CN212320837U discloses a monitoring device for well point dewatering in foundation pit excavation, including multiple connecting rods, multiple fixing blocks, multiple sliding rods, liquid level sensors, and a control box. The multiple connecting rods are detachably connected and each is equipped with a support mechanism.

[0004] However, the existing monitoring devices for dewatering at well points during foundation pit excavation require individual adjustment of the sliding rods before use, which is complex and reduces detection efficiency. Utility Model Content
[0005] The purpose of this utility model is to provide a wellpoint dewatering detection device for foundation pit excavation, which solves the problem that existing monitoring devices for wellpoint dewatering in foundation pit excavation require individual adjustment of sliding rods before use, which is complicated and reduces detection efficiency.
[0006] To achieve the above objectives, this utility model provides a wellpoint dewatering detection device for foundation pit excavation, including a control box, multiple liquid level sensors, multiple sliding rods, and a synchronization mechanism. The synchronization mechanism includes a main cylinder, a secondary cylinder, a tail cylinder, and a drive assembly. The multiple liquid level sensors are located below the control box, and the multiple sliding rods are located below the control box. The main cylinder is rotatably connected to the lower part of the control box, the secondary cylinder is slidably connected to the main cylinder, and the tail cylinder is slidably connected to the secondary cylinder. The drive assembly is located below the control box and includes a drive shaft, multiple drive housings, and multiple drive components. The drive shaft is located inside the tail cylinder. The multiple drive housings are respectively fixedly connected to the bottom of the main cylinder, the secondary cylinder, and the tail cylinder. Each liquid level sensor is fixedly connected to the upper part of each drive housing. The multiple sliding rods are respectively slidably connected to the multiple drive housings, and each drive component is located inside each drive housing.
[0007] The drive shaft includes a main shaft, a secondary shaft, and a tail shaft. The main shaft is fixedly connected to the control box and rotatably connected to the main cylinder. The secondary shaft is slidably connected to the main shaft. The tail shaft is rotatably connected to the tail cylinder and slidably connected to the secondary shaft.

[0011] This utility model discloses a wellpoint dewatering detection device for foundation pit excavation. During detection, the tail cylinder is pulled until the tail cylinder, the secondary cylinder, and the drive shaft are fully extended. The device is then placed at the detection point. The control box is rotated, causing the rotating shaft to rotate and multiple drive components to work. This causes multiple sliding rods to extend synchronously along the drive housing until they abut against the well wall. At this point, detection can be performed using multiple liquid level sensors. This avoids the problem of some foundation pit excavation wellpoint dewatering monitoring devices requiring individual adjustment of sliding rods before use, which is complex and reduces detection efficiency. This device achieves the effect of quickly adjusting sliding rods and improving detection efficiency. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] This utility model provides a wellpoint dewatering detection device for foundation pit excavation: it includes a control box 101, multiple liquid level sensors 102, multiple sliding rods 117, and a synchronization mechanism. The synchronization mechanism includes a main cylinder 103, a secondary cylinder 104, a tail cylinder 105, a drive assembly 106, a chassis 120, and a bottom pad 121. The drive assembly 106 includes a drive shaft 107, multiple drive housings 108, and multiple drive components 109. The drive shaft 107 includes a main shaft 110, a secondary shaft 111, and a tail shaft 112. The drive components 109 include a drive disc 113, a limit disc 114, multiple push-pull rods 118, and multiple drive shafts 119. The aforementioned solution solves the problem that existing wellpoint dewatering monitoring devices for foundation pit excavation require individual adjustment of each sliding rod 117 before use, which is complex and reduces detection efficiency.
[0022] In this specific embodiment, multiple liquid level sensors 102 are located below the control box 101, multiple slide rods 117 are located below the control box 101, the main cylinder 103 is rotatably connected to the lower part of the control box 101, the secondary cylinder 104 is slidably connected to the main cylinder 103, the tail cylinder 105 is slidably connected to the secondary cylinder 104, the drive assembly 106 is disposed below the control box 101, the drive shaft 107 is disposed within the tail cylinder 105, and multiple drive housings 108 are respectively fixedly connected to the bottom of the main cylinder 103, the secondary cylinder 104, and the tail cylinder 105. Each liquid level sensor 102... 2. Fixedly connected above each of the drive housings 108, multiple sliding rods 117 are slidably connected within the multiple drive housings 108 respectively, and each drive component 109 is located within each drive housing 108. During detection, the tail cylinder 105 is pulled until the tail cylinder 105, the secondary cylinder 104, and the drive shaft 107 are fully extended. The device is placed at the detection point, and the control box 101 is rotated, causing the rotating shaft to rotate and the multiple drive components 109 to work, so that the multiple sliding rods 117 extend synchronously along the drive housing 108 until they abut against the well wall. At this time, detection can be performed by multiple liquid level sensors 102. The specific structure and working principle of the liquid level sensor 102 and the control box 101 are described in the patent document with publication number CN212320837U, which is not within the scope of protection of this application and will not be elaborated here.
[0023] The main shaft 110 is fixedly connected to the control box 101 and rotatably connected to the main cylinder 103. The secondary shaft 111 is slidably connected to the main shaft 110. The tail shaft 112 is rotatably connected to the tail cylinder 105 and slidably connected to the secondary shaft 111. Multiple driving components 109 are respectively disposed on the surfaces of the main shaft 110, the secondary shaft 111, and the tail shaft 112. When the tail cylinder 105 is pulled, under the action of the multiple driving components 109, the relative positions of the tail shaft 112 and the tail cylinder 105 remain unchanged, the relative positions of the secondary shaft 111 and the secondary cylinder 104 remain unchanged, and the relative positions of the main shaft 110 and the main cylinder 103 remain unchanged. When the control box 101 is rotated, the main shaft 110 drives the secondary shaft 111 and the tail shaft 112 to rotate, so that the multiple driving components 109 work synchronously, thereby driving the multiple sliding rods 117 to extend and retract synchronously.
[0024] Secondly, the drive disk 113 is disposed on the surface of the drive shaft 107 and is provided with multiple arc grooves 115. The limiting disk 114 is fixedly connected to the drive housing 108 and rotatably connected to the drive disk 113, and is provided with multiple straight grooves 116. Multiple sliding rods 117 are located around the limiting disk 114. When the drive disk 113 is rotated, the main shaft 110, the secondary shaft 111 and the tail shaft 112 rotate, driving the multiple drive disks 113 to rotate and transmitting power. At the same time, the multiple limiting disks 114 restrict the position of the multiple drive disks 113, so that the position of the tail shaft 112 and the tail cylinder 105 remains relatively unchanged, the position of the secondary shaft 111 and the secondary cylinder 104 remains relatively unchanged, and the position of the main shaft 110 and the main cylinder 103 remains relatively unchanged.
[0025] Meanwhile, multiple push-pull rods 118 are slidably connected within the drive housing 108, and multiple drive shafts 119 are rotatably connected within the push-pull rods 118, respectively passing through multiple arc grooves 115 and multiple straight grooves 116. When the drive disc 113 rotates, the drive disc 113 squeezes multiple drive shafts 119 through multiple arc grooves 115, and under the restriction of multiple straight grooves 116, the multiple drive shafts 119 move along the arc grooves 115 and along the straight grooves 116, driving the multiple push-pull rods 118 to extend and retract, thereby controlling the extension and retraction of multiple slide rods 117 through the multiple push-pull rods 118.
[0026] Finally, the chassis 120 is fixedly connected to the bottom of the tail cylinder 105, and the bottom pad 121 is fixedly connected to the bottom of the chassis 120. When the equipment is placed in the testing area, the chassis 120 can make the equipment more stable, and the bottom pad 121 can prevent debris from scratching the chassis 120 and extend the service life of the equipment.
[0027] During testing, pull the tail cylinder 105 until it and the secondary cylinder 104 are fully extended. Because the multiple limiting discs 114 restrict the positions of the multiple drive discs 113, the relative positions of the tail shaft 112 and the tail cylinder 105, the relative positions of the secondary shaft 111 and the secondary cylinder 104, and the relative positions of the main shaft 110 and the main cylinder 103 remain unchanged. At this time, the secondary shaft 111 and the tail shaft 112 are fully extended. Place the equipment in the testing area. The chassis 120 ensures stable placement, and the base pad 121 prevents debris from scratching the chassis 120, extending the equipment's service life. Rotate the control box 101, causing the main shaft 110, secondary shaft 111, and tail shaft 112 to rotate, driving the multiple drive discs 113 to rotate, thereby enabling the drive discs to rotate. When component 109 operates, multiple sliding rods 117 extend synchronously along the drive housing 108 until they abut against the well wall. At this time, multiple liquid level sensors 102 can detect the liquid level. When the drive disc 113 rotates, the drive disc 113 squeezes multiple drive shafts 119 through multiple arc grooves 115. Under the constraint of multiple straight grooves 116, multiple drive shafts 119 move along the arc grooves 115 and along the straight grooves 116, driving multiple push-pull rods 118 to extend and retract. Thus, the extension and retraction of multiple sliding rods 117 are controlled by multiple push-pull rods 118. This avoids the problem that some well point dewatering monitoring devices for foundation pit excavation require individual adjustment of sliding rods 117 before use, which is complicated and reduces detection efficiency. This achieves the effect of quickly adjusting sliding rods 117 and improving detection efficiency.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
