Abstract
Description
Technical Field

[0002] The dewatering well chamber is used to lower the groundwater level or to dry the underground aquifer. It can help improve the construction environment, ensure the smooth progress of the foundation or underground engineering, and also prevent problems such as unstable foundation and leakage caused by excessively high groundwater level. In traditional technology, the groundwater level is generally measured manually. Workers hold a measuring rod or a rope with a counterweight and lower it into the dewatering well. Then, based on experience, they mark the measuring rod or rope at the wellhead, pull out the measuring rod or rope, and measure the distance from the top of the measuring rod or rope to the marked point. Then, the measured distance is subtracted from the distance from the wellhead to the floor, which is the height of the liquid level in the dewatering well. However, the above method is easily affected by water surface fluctuations, resulting in inaccurate measurement results, which is time-consuming and labor-intensive. In addition, the above measurement method can only be detected periodically, not in real-time monitoring, and the measurement efficiency is low. Summary of the invention

DETAILED DESCRIPTION
[0013] The present invention is further described below in conjunction with specific embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.
[0014] A groundwater level measuring device is composed of a precipitation well 1, a support frame 3, a sensor monitoring module, a controller and a battery 10. The support frame 3 is placed above the wellhead of the precipitation well 1. A bobbin 5 is horizontally arranged inside the support frame 3. A drive motor 4 is installed on one side of the bobbin 5 of the support frame 3. The output end of the drive motor 4 is connected to the bobbin 5.
[0015] The sensing monitoring module is composed of an upper liquid level sensor 8, a lower liquid level sensor 9 and a sensing harness 6. One end of the sensing harness 6 is connected to a counterweight 7, and the other end of the sensing harness 6 is wound around a bobbin 5. The counterweight 7 is in a strip shape, and grooves are respectively provided at the upper and lower ends of the counterweight 7. The upper liquid level sensor 8 and the lower liquid level sensor 9 are respectively embedded in the grooves of their corresponding ends.
[0016] In this embodiment, the distance between the upper liquid level sensor 8 and the lower liquid level sensor 9 is 100 mm.
[0017] The battery 10, the drive motor 4, the upper liquid level sensor 8, and the lower liquid level sensor 9 are electrically connected to the controller respectively. The control in this embodiment can be a PLC controller. The upper liquid level sensor 8 and the lower liquid level sensor 9 are respectively used to collect liquid level signals and feed the liquid level signals back to the controller. The controller sends an action command according to the received liquid level signal to control the drive motor 4 to stop.
[0018] In this embodiment, a display screen 12 is also provided (the display screen is a commercially available product, and its brand and model are: ANTHONELU-922U). The display screen 12 is connected to the controller. After the controller receives the signal from the upper liquid level sensor 8 or the lower liquid level sensor 9, the controller transmits the processed liquid level value to the display screen 12 for display. The value displayed on the display screen 12 is the height of the groundwater level.
[0019] A solar panel 11 is laid on the top of the support frame 3 , and the output end of the solar panel 11 is electrically connected to the input end of the battery 10 .
[0020] Four supporting legs are connected to the bottom of the supporting frame 3, and each supporting leg is composed of a telescopic rod 14 and a fixed rod 13. The upper end of the telescopic rod 14 is inserted into the interior of the fixed rod 13 and slides along the inner wall of the fixed rod 13. A threaded hole is provided on the rod wall of the fixed rod 13, and a top screw 15 is connected to the thread in the threaded hole. The top screw 15 extends to the interior of the fixed rod 13 to tighten the telescopic rod 14.
[0021] The lower end of the telescopic rod 14 is fixedly connected to a support block 16 , and the lower surface of the support block 16 can be set as a rough surface or a rubber anti-slip layer 17 to increase the friction between the support block 16 and the ground and improve the stability of the support frame 3 .
[0022] When this embodiment is used, the support frame 3 is erected above the wellhead of the precipitation well 1, the drive motor 4 is started, and the counterweight block 7 is lowered into the precipitation well 1 until the lower liquid level sensor 9 is flush with the outdoor floor 2, the control motor stops running, and the depth of the precipitation well 1 displayed on the display screen 12 is reset to zero; the drive motor 4 is started again until the lower liquid level sensor 9 contacts the liquid surface, the lower liquid level sensor 9 transmits the change signal to the controller, the controller issues an action command according to the received signal, and the drive motor 4 is powered off and stops running; at the same time, the controller transmits the water level data to the display screen 12, and the liquid level height displayed on the display screen 12 is the height value of the liquid level in the well from the outdoor floor 2 at this time.
[0023] When the groundwater level drops, the lower liquid level sensor 9 leaves the liquid surface and transmits the change signal to the controller. The controller receives the signal and sends an action. The drive motor 4 is powered and rotates, so that the reel starts to lower the sensor harness 6, causing the counterweight 7 to drop until the lower liquid level sensor 9 contacts the liquid surface. The lower liquid level sensor 9 transmits the change signal to the controller again, and the controller controls the drive motor 4 to stop running. When the groundwater level rises, when the water level rises and contacts the upper liquid level sensor 8, the upper liquid level sensor 8 transmits a change signal to the controller, and the controller receives the signal and issues an action command, and the drive motor 4 is powered to rotate, so that the reel starts to reel up the sensor harness 6, causing the counterweight 7 to rise until the upper liquid level sensor 8 leaves the liquid surface, and the upper liquid level sensor 8 transmits a change signal to the controller again, and the controller controls the drive motor 4 to stop running; since the distance between the upper and lower liquid level sensors is fixed at 100 mm, the controller can perform error calibration based on this distance, thereby ensuring that the error between the measured water level height and the actual water level height is maintained within a small range.
[0024] The present invention has a simple structure and is easy to operate. The upper and lower liquid level sensors 9 can monitor the change of the groundwater level in the well in real time, thereby increasing the measurement speed and greatly improving the measurement accuracy, thus avoiding the generation of large errors.
[0025] The above description is only the preferred embodiment of the present invention, and does not limit the scope of rights of the present invention. All equivalent changes made by using the contents of the present invention specification and its drawings are included in the scope of rights of the present invention.
