The bottom of the collection tank 8 is connected to an electrically controlled overflow device through a discharge pipe. A liquid level transmitter is installed in the collection tank 8. A control box 10 and a communication box 11 are installed on the fixed plate 5. The electrically controlled overflow device and the control box 10 are electrically connected. The control box 10, the liquid level transmitter, and the communication box 11 are electrically connected. The control box 10 selects a local mode and an automatic mode. In the local mode, the control box 10 directly controls the electrically controlled overflow device. In the automatic mode, the liquid level transmitter sends liquid level information to the communication box 11. The communication box 11 controls the start and stop of the electrically controlled overflow device according to a preset program. The communication box 11 sends control information to the well site monitoring room, so that the well site monitoring room knows the operating status and can adjust the working status of the electrically controlled overflow device through the communication box 11.

[0040] Furthermore, the fixing plate 5 is rectangular, the collection pool 8 is located at one end of the fixing plate 5, and two L-shaped fences 9 are symmetrically fixed at the other end of the fixing plate 5. The entrance is between the two L-shaped fences 9. The control box 10 is connected to the outside of one of the fences 9 by a clamp, and the communication box 11 is connected to the inside of one of the fences 9 by a clamp. The control box 10 is located on the outside for easy manual control.

[0041] Specifically, a foot pedal 6 is provided on the outer wall of the fixed plate 5, and the foot pedal 6 corresponds to the entrance between the two L-shaped fences 9. A drag plate 7 is provided on the opposite end of the foot pedal 6 of the fixed plate 5. The drag plate 7 has through holes, which allows the use of a tow hook to transport the equipment with a vehicle, increasing the mobility of the equipment. The foot pedal 6 makes it easy for users to climb to the top of the fixed plate 5. The drag plate 7 allows the use of a tow hook to transport the equipment with a vehicle, increasing the mobility of the equipment. It can be widely used in various oil and water well operation scenarios, easily achieve rapid relocation, greatly save time and costs, and effectively improve operation efficiency.

[0042] Furthermore, the output port of the electrically controlled discharge device is connected to a connecting pipe 13, and a flow controller 14 and a pressure transmitter 15 are installed on the connecting pipe 13. The flow controller 14 and the pressure transmitter 15 are electrically connected to the communication box 11.

[0043] When in use, the overflow pipeline of the wellhead to be overflowed is laid on the collection pool 8 so that the outlet of the overflow pipeline is in the collection pool 8, and the connecting pipe 13 is connected to the wellhead of the adjacent oil well or the reinjection port of the oil gathering process.

[0044] Furthermore, the electrically controlled discharge device includes a G-type single screw pump 12 and a solenoid valve 16, the solenoid valve 16 being mounted on the discharge pipe.

[0045] Specifically, the solenoid valve 16 is a proportional solenoid valve. The signal contact of the solenoid valve 16 is electrically connected to the flow controller 14. The flow controller 14 is used to measure the liquid volume at the outlet of the G-type single screw pump 12 and forward the data to the communication box 11. At the same time, the flow controller 14 controls the opening degree of the solenoid valve 16 according to the set flow rate to achieve stable flow and pressure delivery.

[0046] Specifically, the collection tank 8 is made of steel plate, and the inner cavity of the collection tank 8 is equipped with a float-type liquid level transmitter 17.

It is used to monitor the liquid level in the collection tank 8 in real time and forward the data to the communication box 11 and interlock with the G-type single screw pump 12. When the liquid level in the collection tank 8 is higher than the set threshold, the pump is interlocked to start and drain the liquid. When the liquid level is lower than the set threshold, the G-type single screw pump 12 stops operating.

[0047] Specifically, the body of the connecting pipe 13 is fixedly connected to the outside of the collection tank 8 by a support, and the end of the connecting pipe 13 is connected to the output end of the G-type single screw pump 12 by a quick connector.

There are two positioning seats 4, which are symmetrically arranged at the bottom of the fixing plate 5, so as to stably support the fixing plate 5 and ensure that the moving wheels 3 do not rub against the bottom of the fixing plate 5 when rotating, thus ensuring the spacing.

[0049] Example 2:

[0050] Based on Example 1, combined with Figure 5 This embodiment provides an internal structure for the control box 10 and the communication box 11.

[0051] The control box 10 includes a main power interface 21, a contactor 22, a control knob 23, a first power interface 24, and a control switch 25. One end of the contactor 22 is electrically connected to the main power interface 21, and the other end of the contactor 22 is electrically connected to the G-type single screw pump 12. The control knob 23 is provided with a first control line and a second control line. The common terminal of the first control line is electrically connected to the coil of the contactor 22, and the common terminal of the second control line is electrically connected to the power terminal of the solenoid valve 16. One end of the control switch 25 is electrically connected to the first power interface 24, and the other end of the control switch 25 is electrically connected to the first contact of the first control line and the second control line, respectively. When the control knob 23 connects the common terminal to the first contact, the control switch 25 controls the start and stop of the contactor 22 and the solenoid valve 16, thereby controlling the G-type single screw pump 12.

[0052] The communication box 11 includes a second power interface 31, a programmable controller 32, and a network communication module 33. The programmable controller 32 is electrically connected to the second power interface 31. The programmable controller 32 is electrically connected to the second contacts of the first control line and the second control line through two control ports respectively. The flow controller 14, the pressure transmitter 15, and the float-type level transmitter 17 are electrically connected to the signal input port of the programmable controller 32 respectively. When the control knob 23 connects the common terminal to the second contact, the programmable controller 32 controls the contactor 22 and the solenoid valve 16 to start and stop, thereby controlling the G-type single screw pump 12.

[0053] Specifically, the main power interface 21 is a three-phase power interface, and the first power interface 24 and the second power interface 31 are both 24V switching power supplies, which are powered through the three-phase power interface. The flow controller 14, pressure transmitter 15, and float-type level transmitter 17 are powered through one of the 24V switching power supplies.

[0054] Specifically, the control switch 25 is a knife switch, a gate switch, or a locking button.

[0055] Specifically, the programmable controller 32 is a PLC controller, and the network communication module 33 is a wired network port module and / or a wireless WIFI module.

[0056] Specifically, the coil of the contactor 22, the 24V switching power supply, the programmable controller 32, the network communication module 33, the flow controller 14, the pressure transmitter 15, and the float-type level transmitter 17 are all grounded.

[0057] The control box 10 controls the overall power switch and operating mode selection of the device. When the mode knob of the control box 10 is switched to local mode, the common terminal is connected to the first contact, and the device can perform local pump start and stop operations to facilitate on-site manual operation and realize manual start and stop. When the mode knob of the control box 10 is switched to automatic mode, the common terminal is connected to the second contact, and the equipment enters the automatic interlocking working mode. When the liquid level in the collection tank 8 is higher than the set threshold, the G-type single screw pump 12 automatically starts to drain the liquid, and when the liquid level in the collection tank 8 is lower than the set threshold, the G-type single screw pump 12 automatically shuts down.

[0058] The network communication module 33 connects to the SCADA system, enabling real-time data monitoring, remote control, interlocking, and other functions of the device.

[0059] The automatic operation principle involves real-time monitoring of the liquid level in the collection tank 8 via a built-in float-type level transmitter 17. Through PLC programming, when the liquid level reaches the height limit of 1.2m, the G-type single screw pump 12 automatically starts to discharge excess fluid through the discharge channel, preventing overflow from the well site. Similarly, when the liquid level reaches the low limit of 0.2m, the G-type single screw pump 12 shuts off, and the solenoid valve 16 closes the discharge pipe.
