Abstract
Description
Technical Field
[0001] This utility model relates to the field of reinjection well technology, and in particular to a dynamic balance control device for water level in reinjection wells. Background Technology
[0002] During the construction process, it is necessary to excavate foundation pits. When there is water in the foundation pit, it is necessary to lower the water level in the foundation pit to the standard requirements, while also ensuring the groundwater level of adjacent buildings. In urban construction, water is usually injected into the recharge well to maintain the groundwater level of adjacent buildings, so as to maintain the dynamic balance of water levels inside and outside the deep foundation pit and prevent the surrounding buildings from collapsing.
[0003] A search revealed Chinese patent application number 202221926495.7, which discloses a dynamic water level balance control device for recharge wells. The device includes a recharge well, a support fixed to one side of the well, a lever hinged to the support via a shaft, a valve body on one side of the support, and a water outlet pipe welded to the outer wall of one side of the valve body, extending into the recharge well. A suspension tank is installed inside the recharge well, and a connecting rope is fixed between the suspension tank and the lever. A valve cavity is located inside the valve body. This invention allows for automatic water injection into the recharge well when the water level drops, causing the weight of the water inside the suspension tank to move the valve column upwards, opening the water passage inside the valve body. As the water rises, the suspension tank experiences buoyancy, causing a spring to gradually move the valve column back to its original position until the water passage inside the valve body closes. This achieves the effect of automatically injecting water into the recharge well, maintaining a balanced water level inside the well, and thus facilitating the dynamic balance of water levels inside and outside the foundation pit.
[0004] The aforementioned patent uses a mechanical suspended bucket control structure to control the water level balance of the reinjection well. In actual use, the suspended bucket is easily affected by the external environment. For example, after long-term use, moss and other debris will adhere to the outside of the suspended bucket, which will increase the mass of the suspended bucket. This will reduce the accuracy of the suspended bucket in detecting the water level, and thus make it impossible to guarantee precise control of the valve. As a result, the dynamic balance treatment effect of the reinjection well water level is poor, and its practicality is not good. Secondly, it is difficult to quickly complete the water level control operation by controlling the water flow of the valve.
[0005] To address this issue, we propose a dynamic balance control device for reinjection well water levels. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a dynamic balance control device for the water level of reinjection wells.
[0007] The present invention solves its technical problem through the following technical solution: It includes a base, a mounting bracket fixed to the top of the base, a recharge well body fixed to the inner wall of the base, a sealing cover on the top of the recharge well body, a drainage pool on one side of the base, a detection mechanism at the bottom of the sealing cover, the detection mechanism including a mounting base fixed to the bottom of the sealing cover, a mounting column fixed to the inner wall of the mounting base, multiple slots on one side of the mounting column, a liquid level sensor body fixed to the top of the mounting column by bolts, a connecting cable fixed to the bottom of the liquid level sensor body, a detection probe fixed to one end of the connecting cable, and a recharge mechanism on one side of the mounting bracket.
[0008] The reinjection mechanism includes a reinjection water pump, which is fixed to one side of the mounting bracket by bolts. An inlet pipe is fixed to one side of the reinjection water pump, and a drain pipe A is fixed to the other side of the reinjection water pump. A three-way valve is fixed to one end of the drain pipe A, and a connecting pipe is fixed to one side of the three-way valve. An installation sleeve is fixed to one end of the connecting pipe, and a reinjection water pipe is fixed to the bottom of the installation sleeve. An adjustment mechanism is provided at the top of the installation sleeve, and a recirculation mechanism is provided inside the main body of the reinjection well.
[0009] As a further improvement of this utility model, a control panel is provided on one side of the mounting bracket.
[0010] As a further improvement of this utility model: a positioning plate is provided on the outer side of the detection probe, and the positioning plate is fixedly connected to the mounting column.
[0011] As a further improvement of this utility model, a drain pipe B is fixed to the top of the three-way valve.
[0012] As a further embodiment of this utility model: the adjusting mechanism includes a mounting column, which is fixed to the top of the mounting sleeve by bolts. A motor mounting block is fixed to the top of the mounting column, and a geared motor is fixed to the top of the motor mounting block by bolts. A screw is fixed to the output end of the geared motor, and a threaded sleeve is threaded to the outer side of the screw. A drive plate is fixed to the bottom of the threaded sleeve, and an adjusting column is fixed to the bottom of the drive plate. The adjusting column is slidably connected to the mounting sleeve.
[0013] As a further improvement of this utility model: a limiting slider is fixed on the outer side of the threaded sleeve, and the limiting slider is slidably connected to the mounting column.
[0014] As a further embodiment of this utility model: the recharge mechanism includes a recharge water pump, which is disposed on the inner wall of the recharge well body. A water delivery pipe is fixed to the top of the recharge water pump, and a support plate is fixed to the outside of the water delivery pipe. The support plate is fixedly connected to the drainage pool.
[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0016] 1. When installing the recharge well, the mounting base is installed at the bottom of the main body of the recharge well, and then the mounting column is installed inside the mounting base. The detection probe and connecting cable are placed inside the mounting column. Finally, the liquid level sensor body is installed on the top of the mounting column. Water in the recharge well enters the interior of the mounting column through the slot, which can limit the installation of the connecting cable and detection probe and prevent the connecting cable and detection probe from being affected by the water flow.
[0017] 2. The water pressure at the location is detected by a probe and compared with the external standard atmospheric pressure to determine the liquid level inside the reinjection well. When the liquid level is too high, the flow rate of water entering the reinjection pipe is controlled by an adjustment mechanism to gradually lower the water level inside the reinjection well, thus achieving dynamic balancing of the water level. This testing method is not easily affected by external environmental interference, ensuring the accuracy of water level detection after long-term use. This allows the adjustment mechanism to achieve high-precision water level control, ensuring the effectiveness of dynamic balancing control of the reinjection well water level and improving the practicality of the device.
[0018] 3. By installing a drain pipe B, when the water level is too high, the flow rate of water entering the reinjection pipe is controlled by the regulating mechanism. At the same time, a portion of the water is directed into the drain pipe B through a three-way valve, and finally the water is injected into the drainage tank. This can quickly reduce the water flow rate inside the connecting pipe, so that the water level inside the reinjection well can be quickly lowered, ensuring the efficiency of the water level control operation.

[0030] Please see Figure 1-6This utility model provides a technical solution: it includes a base 100, a mounting bracket 110 fixed on the top of the base 100, a control panel 120 on one side of the mounting bracket 110, a reinjection well body 130 fixed on the inner wall of the base 100, a sealing cover 131 on the top of the reinjection well body 130, a drainage pool 140 on one side of the base 100, a detection mechanism at the bottom of the sealing cover 131, the detection mechanism including a mounting base 210, a mounting column 220, a slot 221 and a liquid level sensor body 230, a connecting cable 231 fixed at the bottom of the liquid level sensor body 230, a detection probe 240 fixed at one end of the connecting cable 231, and a reinjection mechanism on one side of the mounting bracket 110;
[0031] The reinjection mechanism includes a reinjection water pump 310, an inlet pipe 311, and a drain pipe A320. A three-way valve 330 is fixed to one end of the drain pipe A320, and a connecting pipe 340 is fixed to one side of the three-way valve 330. An installation sleeve 350 is fixed to one end of the connecting pipe 340, and a reinjection water pipe 351 is fixed to the bottom of the installation sleeve 350. An adjustment mechanism is provided at the top of the installation sleeve 350. A recirculation mechanism is provided inside the main body 130 of the reinjection well. By incorporating a detection mechanism and a reinjection mechanism, when laying out the reinjection well, the mounting base 210 is installed at the bottom of the main body 130 of the reinjection well, and then the mounting column 220 is installed inside the mounting base 210. A detection probe 240 and a connecting cable 231 are placed inside the mounting column 220. Finally, the liquid level sensor body 230 is installed on the mounting column 220. At the top, water from the reinjection well enters the mounting column 220 through the slot 221, which limits the installation of the connecting cable 231 and the detection probe 240, preventing them from being affected by the water flow. The detection probe 240 detects the water pressure at its location and compares it with the external standard atmospheric pressure to determine the liquid level inside the reinjection well. When the liquid level is too high, the flow rate of water entering the reinjection water pipe 351 is controlled by the adjustment mechanism, so that the water level inside the reinjection well can be gradually reduced, achieving dynamic balance operation of the water level in the reinjection well. This testing method is not easily affected by external environmental interference, ensuring the accuracy of water level detection operation after long-term use. This allows the adjustment mechanism to achieve high-precision water level control, ensuring the effect of dynamic balance control of the water level in the reinjection well and improving the practicality of the device.
[0032] Specifically, a positioning plate 241 is provided on the outer side of the detection probe 240, and the positioning plate 241 is fixedly connected to the mounting column 220. By providing the positioning plate 241 to further position and fix the detection probe 240, it is possible to ensure that the detection probe 240 is not frequently bumped against the inner wall of the mounting column 220, thus ensuring the service life of the detection probe 240.
[0033] Specifically, a drain pipe B331 is fixed to the top of the three-way valve 330. By setting up the drain pipe B331, when the water level is too high, the water flow rate entering the reinjection pipe 351 is controlled by the regulating mechanism. At the same time, a portion of the water is introduced into the drain pipe B331 through the three-way valve 330, and finally the water is injected into the drainage pool 140. This can quickly reduce the water flow rate in the connecting pipe 340, so that the water level in the reinjection well can be quickly lowered, ensuring the efficiency of the water level control operation.
[0034] Specifically, the adjustment mechanism includes a mounting column 410, which is bolted to the top of the mounting sleeve 350. A motor mounting block 420 is fixed to the top of the mounting column 410, and a reduction motor 430 is bolted to the top of the motor mounting block 420. A screw 431 is fixed to the output end of the reduction motor 430, and a threaded sleeve 440 is threaded to the outer side of the screw 431. A drive plate 450 is fixed to the bottom of the threaded sleeve 440, and an adjustment column 460 is fixed to the bottom of the drive plate 450. The adjustment column 460 is slidably connected to the mounting sleeve 350. By setting an adjustment mechanism to drive the adjustment column 460 to move, the flow rate of water entering the reinjection water pipe 351 from the connecting pipe 340 is adjusted, which can reduce the speed at which water enters the reinjection well. The detection mechanism detects the water level in real time, and the adjustment mechanism also adjusts the water flow rate to achieve dynamic balance operation of the water level in the reinjection well.
[0035] Specifically, a limiting slider 441 is fixed on the outer side of the threaded sleeve 440, and the limiting slider 441 is slidably connected to the mounting post 410; by setting the limiting slider 441, the up and down movement of the threaded sleeve 440 is limited and supported, ensuring that the threaded sleeve 440 can only move up and down, and preventing the threaded sleeve 440 from rotating during adjustment operations.
[0036] Specifically, the backfilling mechanism includes a backfilling water pump 510, which is installed on the inner wall of the backfilling well body 130. A water delivery pipe 520 is fixed to the top of the backfilling water pump 510, and a support plate 530 is fixed to the outside of the water delivery pipe 520. The support plate 530 is fixedly connected to the drainage tank 140. Because of the backfilling mechanism, water carrying a large number of air bubbles enters the well during the backfilling process, which can easily form rust. Therefore, a backfilling water pump 510 needs to be installed in the backfilling well to backfill the well. During the backfilling process, the water in the backfilling well is processed by the backfilling water pump 510 and transported to the water delivery pipe 520. The water then enters the drainage tank 140 through the water delivery pipe 520.
[0037] Working Principle: During use, the device is controlled via the control panel 120. When laying out the reinjection well, the mounting base 210 is installed at the bottom of the reinjection well body 130, and then the mounting column 220 is installed inside the mounting base 210. The detection probe 240 and the connecting cable 231 are placed inside the mounting column 220. Finally, the liquid level sensor body 230 is installed at the top of the mounting column 220. Water in the reinjection well enters the mounting column 220 through the slot 221, which limits the installation of the connecting cable 231 and the detection probe 240, preventing them from being affected by the water flow. The detection probe 240 detects the water pressure at its location and compares it with the external standard atmospheric pressure to determine the liquid level inside the reinjection well. Under normal reinjection conditions, the adjusting column 460 is at its highest position. The reduction motor 430 drives the screw 431 to rotate, and the rotation of the screw 431 drives the threaded sleeve 440 upward. The downward movement of the threaded sleeve 440 drives the drive plate 450 and the adjusting column 460 to move. The movement of the adjusting column 460 adjusts the water flow rate into the reinjection pipe 351 through the connecting pipe 340, which reduces the speed at which water enters the reinjection well. The detection mechanism detects the water level in real time, and the adjustment mechanism also adjusts the water flow rate to achieve dynamic balance of the water level in the reinjection well. At the same time, a portion of water is introduced into the drainage pipe B331 through the three-way valve 330, and finally the water is injected into the drainage pool 140. This can quickly reduce the water flow rate in the connecting pipe 340, so that the water level in the reinjection well can drop rapidly. During the reinjection process, the water carries a large number of air bubbles into the well, which can easily form rust. Therefore, a return pump 510 needs to be installed in the reinjection well to perform return treatment. During the return treatment, the water in the reinjection well is processed by the return pump 510 and transported to the water delivery pipe 520. The water enters the drainage pool 140 through the water delivery pipe 520.
