Description

Technical Field

[0001] The utility model relates to the technical field of energy storage battery compartments, and more specifically, the utility model relates to a coolant filling device for an energy storage battery compartment. Background Art

[0002] In recent years, the installed capacity of energy storage battery compartments has shown an explosive growth. At the same time, problems in the liquid filling of energy storage battery compartments have gradually emerged. The existing environmental conditions of energy storage power stations are generally remote in geographical location and poor in environmental conditions; the area of energy storage power stations is large, the energy storage battery compartments are widely distributed and relatively scattered; the number of energy storage battery compartments in the station is large, and the liquid filling volume is large; in addition, the energy storage battery compartments are tall and have concrete foundations, which also increases the difficulty of liquid filling.

[0003] At present, the method of filling the energy storage battery compartment with liquid is generally manual filling. It is difficult to finely adjust the flow rate and velocity of the coolant, and there may be situations of overfilling or underfilling, which will affect the performance and safety of the battery. At the same time, a variety of tools and equipment are required during the liquid filling process, such as a liquid filling pump, a power supply, a control switch, a liquid filling pipe, a liquid filling connector, an electrical socket, etc. Since the liquid filling tools and equipment are relatively scattered and restricted by the environment, location, and the length of the pipeline, when filling different energy storage battery compartments each time, multiple devices need to be moved, which takes a long time. Frequent movement will not only cause a risk of leakage of the pump and the liquid pipe, but also pose a certain safety hazard due to the easy entanglement or stretching and tension of the wires of multiple devices.

[0013] The technical effects and advantages of the present utility model:

[0014] 1. By setting the liquid injection mechanism, the flow rate and flow velocity of the coolant are precisely adjusted through the electro-hydraulic proportional regulating valve, realizing the refined control of the liquid injection process. The flow sensor can measure the liquid injection volume and liquid injection speed in real time, providing accurate data support for automatic liquid injection control, ensuring the accuracy and consistency of each liquid injection, avoiding the battery performance damage or safety problems that may be caused by inaccurate liquid injection volume. The entire liquid injection process realizes automatic filling from the liquid inlet to the final connection with the liquid injection interface of the energy storage battery cabin, reducing manual intervention, improving work efficiency, and at the same time avoiding the leakage risk of the pump and liquid pipe caused by frequent movement, and also solving the problem that the wires of multiple devices are prone to entanglement or being in a stretched and tight state, causing certain safety hazards when using multiple devices for liquid injection;

[0015] 2. The filter can effectively remove impurities in the coolant, ensuring that no impurities enter the battery cabin, thereby protecting the normal operation of the battery and extending the service life of the battery. When the pressure is too high, the safety valve can automatically relieve pressure, ensuring the safe operation of the system and preventing safety accidents such as pipeline rupture and leakage caused by too high pressure. The height of the liquid injection connector can be conveniently adjusted by splicing or disassembling multiple extension pipes, so as to facilitate the adjustment of the liquid injection height, and the applicability is higher.

[0025] As shown in the Figure 1 and 2, as shown in Figures 4 and 5, the liquid inlet connector 4, the electro-hydraulic proportional regulating valve 6, and the flow sensor 7 are all fixedly installed on the top of the vehicle cabin 1. A safety valve 15 is installed at the end of the first liquid injection pipe 8, which facilitates automatic pressure relief through the safety valve 15 to prevent danger caused by excessive pressure.

[0026] As shown in the appendix Figures 1-4 , the cross-sectional shape of the second liquid injection pipe 12 is set to an L shape. The end of the second liquid injection pipe 12 penetrates through the connecting pipe 11 and extends into the connecting pipe 11, which facilitates the coolant inside the connecting pipe 11 to flow into the second liquid injection pipe 12.

[0027] As shown in the appendix Figure 1 , 2 , as shown in Figures 4 and 5, the liquid injection pump 2, the electro-hydraulic proportional regulating valve 6, the flow sensor 7, and the safety valve 15 are all electrically connected to the single-chip microcomputer 14, which facilitates controlling the opening and closing of the electro-hydraulic proportional regulating valve 6 and the safety valve 15 through the single-chip microcomputer 14.

[0028] As shown in the appendix Figure 3 , the ends of the liquid injection riser pipe 9 and the extension pipe 10 are both provided with threaded holes 19.

[0030] Working principle of the utility model: During the use of a coolant filling device for an energy storage battery compartment provided by the utility model, the liquid injection pump 2 provides power for the filling of the coolant. The coolant enters the liquid inlet connector 4 from the liquid inlet pipe 3 through the liquid inlet pipe. Driven by the liquid inlet connector 4, the coolant flows towards the filter 5. The filter 5 filters the coolant to remove impurities therein, ensuring that no impurities enter the battery compartment. The filtered coolant then flows towards the electric proportional regulating valve 6. The electric proportional regulating valve 6, as an actuator for controlling the flow rate and velocity of the liquid injection pipeline, precisely controls the flow rate and velocity of the coolant by sending a signal from the single-chip microcomputer 14 to the electric proportional regulating valve 6. The flow sensor 7 is used to measure the filling volume and filling speed and participates in the automatic control of coolant filling. It successively passes through the first liquid injection pipe, the liquid injection riser pipe, the extension pipe, the connecting pipe, and the second liquid injection pipe, and finally flows out from the liquid injection connector 13 and docks with the liquid injection interface of the energy storage battery compartment to achieve automatic filling of the coolant. When the pressure of the liquid injection system exceeds the pipeline limit value, the safety valve is automatically depressurized by controlling the single-chip microcomputer 14 to ensure the safety of the system. When it is necessary to increase the filling speed, the opening of the electric proportional regulating valve is increased by controlling the single-chip microcomputer 14 to increase the flow rate. At the same time, the flow sensor 7 monitors the filling speed and volume in real time.

[0031] Finally: The above embodiments are only illustrative of the principles and effects of the utility model and are not intended to limit the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the utility model should still be covered by the claims of the utility model.
