The existing groundwater level monitoring method is generally through manual measurement, that is, setting a water level observation pipe through drilling, and then manually measuring it on site using a measuring rope or water level meter. After obtaining the data, it is manually determined whether the groundwater level exceeds the warning value, and the recharging equipment is manually turned on for recharging. During this period, the change range of the groundwater level is manually measured to determine whether to stop, reduce or increase the recharging volume. This method is time-consuming and labor-intensive, and the accuracy of the monitoring data is difficult to guarantee, which cannot meet the requirements of information management of foundation pit construction. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a digital-based groundwater level monitoring and recharge linkage device and a use method, which can monitor the groundwater level and the operation of the recharge equipment in real time and save monitoring costs.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A digital-based groundwater level monitoring and recharge linkage device, comprising a control box, a float valve group, an integrated solenoid valve flowmeter valve group, a smart construction site control center, and a mobile phone terminal. The control box comprises a manual / automatic control module, including a manual / automatic / off knob. When in the automatic state, the manual / automatic control module can receive signals from the float valve group and the smart construction site control center; the manual state is used for backwashing of the recharge well; when in the off gear, the control box cannot receive signals from the float valve group and the smart construction site control center; the manual gear is used for backwashing of the recharge well.

[0006] Preferably, the control box comprises a display, and the display can display and set the groundwater level and the operating status of the electromagnetic valve flow meter integrated valve in real time.

[0007] Preferably, the control box comprises an indicator light (13), which is composed of a power indicator light, an operation indicator light, and a fault indicator light, and can display the working status of the control box in real time.

[0008] Preferably: the control box comprises a cable 1, wherein the cable 1 can transmit the control box valve opening / closing signal to the electromagnetic valve flow meter integrated valve group, and feed back the electromagnetic valve flow meter integrated valve group opening / closing signal to the control box;

[0009] The control box includes cable 2, which can feed back the action signals of the electromagnetic valve flowmeter integrated valve group and the float valve group to the smart construction site control center through the control box; the control box includes cable 3, which can transmit the signal of the smart construction site control center to the control box.

[0010] Preferably: the solenoid valve flowmeter integrated valve group includes a water collection main pipe, a solenoid valve flowmeter integrated valve, and a recharging branch pipe. The solenoid valve flowmeter integrated valve is installed between the water collection main pipe and the recharging branch pipe, and is connected to the control box through cable 1.

[0011] Preferably, the float valve assembly comprises cable four and a float valve, wherein the cable four transmits a height signal of the float valve to a control box; and the float valve moves up and down according to the underground water level and generates a signal.

[0012] Preferably: the smart construction site control center can centrally set and display the working status of all control boxes, float valve groups, and solenoid valve flow meter integrated valve groups, and transmit the information to the mobile phone mobile terminal.

[0013] Preferably: the mobile phone can install the enterprise customized application APP and display the solenoid valve flow meter integrated valve plate opening / closing, recharge flow, recharge volume, current water level data and graphics transmitted by the smart construction site control center through the network.

[0014] A method for using a digital groundwater level monitoring and recharging linkage device, the steps are as follows:

[0015] Step 1: Set up the control box near the water level observation well, and install the float valve group and the solenoid valve flow meter integrated valve group in sequence. The control box, float valve group, and solenoid valve flow meter integrated valve are connected by cables, and the cables are laid in a concealed manner. Set the installation height of the float valve on the display according to the groundwater level warning value, and check whether the power indicator light is on and whether the manual / automatic / off knob is in the automatic position;

[0016] Step 2: When the groundwater level is lower than the warning value, the float valve is suspended in the air and sends a start signal which is transmitted to the manual / automatic control module through cable 4. The manual / automatic control module receives the start signal of the float valve and sends a start signal to the solenoid valve flow meter integrated valve through cable 1. After receiving the signal from the manual / automatic control module, the solenoid valve flow meter integrated valve starts the valve plate to inject water into the recharge well. The operation indicator light is on, the valve plate is opened, and the current recharge flow and recharge volume are displayed in real time on the display screen. The manual / automatic control module transmits the data to the smart construction site control center through cable 2 at the same time.

[0017] Step 3: When the groundwater level rises above the warning value, the float valve rises and sends a closing signal which is transmitted to the manual / automatic control module through cable 4. The manual / automatic control module receives the closing signal of the float valve and sends a closing signal to the solenoid valve flow meter integrated valve through cable 1. The solenoid valve flow meter integrated valve closes the valve plate after receiving the signal from the manual / automatic control module, stops injecting water into the recharging well, the operation indicator light goes out, the valve plate is closed, and the current water level height is displayed in real time on the display. The manual / automatic control module also transmits the data to the smart construction site control center through cable 2.

[0018] Step 4: When the recharging well is severely blocked due to long-term use and needs to be flushed by pumping water back through the recharging branch pipe, adjust the knob to the manual gear, and the manual / automatic control module sends a start signal to the solenoid valve flow meter integrated valve through the cable. After the solenoid valve flow meter integrated valve receives the signal from the manual / automatic control module, it starts the valve plate to drain water to the water collection main pipe;

[0019] Step 5: The smart construction site control center can transmit the start / close signal of the solenoid valve flow meter integrated valve to the manual / automatic control module through cable three, and transmit the reinjection flow, reinjection volume, current water level data and graphics to the mobile phone through the network to realize remote control and remote inspection.

[0020] Compared with the prior art, the digital groundwater level monitoring and recharge linkage device and use method of the present invention have the following beneficial effects:

[0021] 1. By setting up the manual / automatic control module of the control box, the water level in the water level observation well and the solenoid valve flow meter integrated valve can be monitored in real time, thus saving manpower and reducing monitoring costs;

[0022] 2. By connecting the manual / automatic control module of the control box to the smart construction site control center, the underground water level, recharge flow rate, and recharge volume data of each water level observation well can be displayed centrally, and the start / shutdown of the solenoid valve flowmeter integrated valve can be centrally controlled, thus saving manpower;

[0023] 3. Through the smart construction site control center, the statistical data of groundwater level, recharge flow and recharge volume of each water level observation well are transmitted to the mobile phone in real time. On-site inspectors can grasp the trend of groundwater level changes and equipment operation status in real time, thus saving manpower. BRIEF DESCRIPTION OF THE DRAWINGS
