Description

Technical Field

[0001] The utility model belongs to the technical field of dewatering wells, and particularly relates to a device for measuring the water level of a drain pipe of a dewatering well. Background Technique

[0002] At present, during the construction of a foundation pit, the water level inside the dewatering well needs to be monitored. Therefore, a device for measuring the water level of the dewatering well is required to prevent a sudden large change in the water level inside the dewatering well and avoid the occurrence of water inrush.

[0003] The existing device for measuring the water level of a dewatering well generally uses a measuring rope to monitor the water level. One end of the measuring rope is connected to a multimeter, and the other end is sent into the dewatering well. By using the surface and the well water to form a circuit and display it on the multimeter, the measurement of the water level inside the dewatering well is achieved. However, during the use process, the staff needs to manually release the rope and slowly put the measuring rope into the dewatering well for water level measurement. The entire measurement process takes a lot of time, and the staff needs to always stay at the dewatering wellhead for observation, increasing the work difficulty of the staff, reducing the measurement efficiency, and being not conducive to people's use.

[0004] Therefore, we provide a device for measuring the water level of a drain pipe of a dewatering well to solve the above problems. Content of the Utility Model

[0017] The present utility model has the following beneficial effects:

[0018] 1. Through the setting of the automatic retracting and releasing component, the present utility model can open the measuring pipe and the braking mechanism, and then the detection head drives the measuring rope into the conveying pipe due to its own weight. By continuously paying out the line until the detection head contacts the groundwater, a loop is formed between the ground surface and the groundwater and is displayed on the multimeter. At this time, the controller controls the braking mechanism to lock the winding roller and starts the sound and light alarm to remind the staff that the measurement is completed. The staff can then record the measurement result without having to stay at the dewatering well body all the time to observe and pay out the line.

[0019] 2. Through the setting of the measurement counting component, the present utility model can count by the cooperation of the counting bumps arranged on the surface of the measuring rope and the trapezoidal blocks. When the measuring rope follows the detection head and falls into the conveying pipe, the counting bumps arranged every one meter will squeeze the inclined surface of the trapezoidal block, causing the trapezoidal block to push the counting button of the counter, and the counter completes a counting operation until the detection head contacts the well water. The number displayed on the counter is the depth of the well water inside the dewatering well body, and the staff can directly record it without having to observe the measuring rope label anymore.

[0020] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Please refer to Figures 1-5 , on the basis of Specific Embodiment One and Specific Embodiment Two, a reinforcing plate is fixedly connected to the bottom of the rear side of the mounting frame 501, and the bottom of the reinforcing plate is fixedly connected to the baffle 2. A multimeter 10 is fixedly connected to the left side of the front side of the mounting frame 501. A controller 11 is fixedly connected to the right side of the front side of the mounting frame 501. An audible and visual alarm 12 is fixedly connected to the left side of the top of the mounting frame 501. A sealing cover is threadedly connected to the top of the measuring pipe 4. A valve is sleeved on the surface of the conveying pipe 3.

[0037] Specifically: The shape of the reinforcing plate is triangular. The front side of the bottom of the reinforcing plate is fixedly connected to both the mounting bracket 501 and the baffle 2 by welding. The multimeter 10 can cooperate with the detection head 506 and the measuring rope 504 to detect the water level inside the dewatering well body 1. The sound and light alarm 12 can remind the staff that the measurement is completed. The sealing cover can block the measuring pipe 4, and the valve can control the opening and closing of the conveying pipe 3.

[0038] The working principle of the present utility model is as follows: Close the valve and open the sealing cover. Then, start the second motor 5072. The second motor 5072 cooperates with the screw rod 5073 to drive the threaded sleeve 5074 and the connecting rod 5075 to move. The movement of the connecting rod 5075 drives the pressing plate 5076 and the arc plate 9 not to be in close contact with the winding roller 503. At this time, due to the self-weight of the detection head 506, the measuring rope 504 slowly moves downward. When the detection head 506 contacts the groundwater, a circuit is formed between the ground surface and the groundwater and is displayed on the multimeter 10. Then, the controller 11 controls the pressing plate 5076 to continue moving downward to lock the winding roller 503. At the same time, the sound and light alarm 12 is activated to remind the staff that the measurement is completed. When the measuring rope 504 falls, the counting bumps 505 on its surface continuously squeeze the trapezoidal block 604, causing the trapezoidal block 604 to move and squeeze the counting button of the counter 606. The length of the measuring rope 504 is recorded by the counter 606. When the staff arrives at the dewatering well body 1, they can directly record the value without observing the label of the measuring rope 504. After the detection is completed, start the first motor 502 to make the winding roller 503 collect the measuring rope 504. The whole process does not require manual operation by the staff, improving the detection efficiency.
