During the filling process of the connecting liquid, the bubbles retained in the liquid pipe should be reduced as much as possible. At the same time, for longer monitoring lines, the filling speed should be accelerated to improve the operation efficiency. At present, there are generally two ways of filling: 1. Manual filling, placing the filling port at a high place, and filling by the gravity flow of the liquid itself. The flow rate is slow, and the bubbles adhered to the liquid pipe are not easy to be discharged, and the efficiency is low; 2.

[0019] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the utility model is now described.
[0020] The utility model provides a liquid filling device for a static level monitoring system to improve the quality and efficiency of connecting liquid filling and reduce the damage to the static level caused by excessive pressure. The device includes a mounting frame 1, a pressure tank 2, a liquid pump 3 and a digital pressure gauge 4. Figure 1 and Figure 2 The specific settings are as follows:
[0021] The mounting frame 1 is composed of a 2mm thick stainless steel plate and a stainless steel pipe with a specification of φ15mm and a thickness of 1mm. A handle 7 is installed on the top to facilitate the movement and transportation of the device. The pressure tank 2 and the liquid pump 3 are both arranged on the mounting frame 1. The pressure tank 2 is fixed to the mounting frame 1 by bolts. The pressure tank 2 adopts an acrylic tank body with a specification of φ100mm and a thickness of 4mm. The bottom of the pressure tank 2 is provided with a liquid outlet pipe 21 and a liquid outlet valve 25. The liquid outlet valve 25 is connected to the liquid outlet pipe 21 to control the filling process. The middle part of the pressure tank 2 is provided with a liquid inlet pipe 22, which is connected to one side of the liquid pump 3. The other side of the liquid pump 3 is provided with a liquid suction pipe 31, which is used to be inserted into a container containing a connecting liquid. The liquid suction pipe 31 and the liquid outlet pipe 21 are respectively arranged on opposite sides of the mounting frame 1 to facilitate smoother circulation of the filling liquid. The liquid pump adopts a 12V diaphragm pump, with a flow rate of 4L / min and a maximum pressure of 400Kpa, and has a self-priming function. The pressure tank 2 is vertically arranged on the mounting frame 1, and the vent valve 24 extends out of the top of the mounting frame 1 to facilitate ventilation. The vent valve 24 is arranged on the top of the pressure tank 2. The pressure tank liquid inlet pipe 22, the vent valve 24, and the pressure tank liquid outlet valve 25 are installed on the pressure tank 2 by punching and bonding;
[0022] The upper part of the pressure tank 2 is also provided with a pressure sensing connecting pipe 23, which is also installed on the pressure tank 2 by punching and bonding. The digital pressure gauge 4 is arranged on the outside of the pressure tank 2, and the digital pressure gauge 4 is connected to the pressure tank 2 through the pressure sensing connecting pipe 23. The digital pressure gauge 4 is also called a pressure control system. The digital pressure gauge 4 adopts an SMC digital pressure gauge, which is an NPN collector open circuit output with a pressure range of -0.1MPa to 1.0MPa. The digital pressure gauge 4 is connected to the electric control board 52. After the digital pressure gauge 4 is connected to the circuit board, the pressure threshold control can be realized.
[0023] Furthermore, the liquid filling device of the static level monitoring system also includes a power supply system, which includes a lithium-ion battery 51 and an electric control board 52 connected to the lithium-ion battery 51. The power supply system uses a 12V10AH (indicates that the voltage level is 12v and the battery capacity is 10AH) lithium-ion battery 51. After the lithium-ion battery 51 is connected to the electric control board 52, it supplies power to various electrical devices of the device.
[0024] The liquid filling device of the static level monitoring system also includes a control box 6. The lithium-ion battery 51, the liquid pump 3 and the electric control board 52 are installed inside the control box 6 by bolts to ensure the safety of the staff. The digital pressure gauge 4 is arranged on the outer panel of the control box 6 for easy observation and detection. The control box 6 is provided with an adjustment button 61 and a power switch 62, and the adjustment button 61 and the power switch 62 are both arranged on the outer panel of the control box 6 for easy operation by the staff.
[0025] Furthermore, the device is provided with a flow control system, which adopts a PWM digital stepless flow regulation element, with an input range of DC12V~24V / 30A, an output voltage DC0~24V, and an output current of 0~30A. After being connected to the electronic control board 52, the flow control system can control the flow of the liquid pump 3 by adjusting the button 61.
[0026] During the actual operation of the utility model, two people are required to operate it. First, the device is placed flat near the filling port of the connecting pipe of the static level monitoring system, the connecting pipe to be filled with liquid is connected to the valve 25 of the pressure tank outlet pipe, and the suction tube 31 is inserted into the container containing the connecting liquid, the pressure tank outlet pipe valve 25 is closed, the air vent valve 24 is opened, the power switch 62 is turned on, and the adjustment knob 61 (flow adjustment button) is adjusted to make the liquid flow at an appropriate speed. After the liquid level in the pressure tank 2 is slightly higher than the position of the pressure tank inlet pipe 22, the flow adjustment knob is rotated and stopped, the air vent valve 24 is closed, and the pressure tank outlet pipe valve 25 is opened to prepare to start filling. Set the pressure control value of the digital pressure gauge 4, turn the adjustment knob 61, and gradually increase the flow rate until the pressure value reaches about 60% of the control value. After the filling begins, another person follows the liquid level in the connecting pipe for tracking and observation. When the connecting pipe is found to be leaking or blocked, promptly notify the filling operator to stop the flow adjustment knob and close the pressure tank outlet pipe valve 25. After the connecting pipe is repaired, the filling operator opens the pressure tank outlet pipe valve 25, turns the flow adjustment knob to a suitable position and continues to fill the connecting liquid, and so on until the connecting liquid fills the entire static level monitoring system's connecting pipe and liquid storage tank.
[0027] Due to the filling of the connecting liquid in the static level monitoring system, the bubbles in the liquid pipe should be reduced as much as possible, and the filling pressure should be controlled within the pressure allowable range of the static level. At the same time, since some monitoring lines are as long as hundreds of meters, the filling speed of the connecting liquid should also be increased. However, it is difficult to simultaneously achieve the above requirements of the filling of the connecting liquid by the traditional filling method. The utility model designs a filling device for a static level monitoring system. First, the connecting liquid is filled to the position above the liquid inlet pipe 22 of the pressure tank through a liquid pump 3, and then the connecting liquid is filled into the connecting pipe. In this way, the bubbles generated during the filling process can be eliminated after passing through the pressure tank, saving the working hours consumed by the secondary removal of bubbles. Then, the filling pressure is controlled within the allowable value range through the digital pressure gauge 4 to avoid overpressure damage to the static level. Therefore, the utility model uses the pressure tank 2 to remove the bubbles generated during the filling, and at the same time uses the pressure control system to accurately control the filling pressure, and through the flow control system, the filling process is made more continuous and stable, thereby improving the quality and efficiency of the filling of the connecting liquid.
[0028] The above description is only an illustrative embodiment of the utility model and is not intended to limit the scope of the utility model. The components of the utility model can be combined with each other without conflict, and any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model.
