Description

Technical Field

[0001] This utility model relates to the field of safety valves, specifically to a fire safety valve for use outside energy storage equipment. Background Technology

[0002] Currently, centralized monitoring systems, battery management systems, and thermal management systems for new energy storage equipment are widely used for power smoothing, peak shaving and valley filling, stabilizing new energy access, and improving the efficiency of renewable energy power generation.

[0003] With the continuous increase in energy demand and the continuous adjustment of energy structure, energy storage technology has become a new type of energy storage equipment. It has strong application prospects in solving the imbalance between power supply and demand and improving energy utilization efficiency. When industrial and commercial energy storage cabinets store electrical energy in battery packs, the cabinets will store excess electrical energy. During the storage and discharge process, a certain amount of heat will be generated, or a large amount of heat will be generated due to the failure of battery cells. This will cause the pressure difference between the inside and outside of the industrial and commercial energy storage cabinet to become unbalanced, which will create safety hazards. Therefore, an external fire safety valve is required to discharge the gas after failure. In order to ensure the safe and stable operation of energy storage equipment, each device must be equipped with a fire safety valve.

[0004] The function of a fire safety valve is to provide waterproofing and venting. When a short circuit or other fault causes a sudden increase in humidity and pressure inside the chamber, and the pressure exceeds the safe value, the venting valve opens to release pressure, quickly balance the pressure, and cope with extreme pressure.

[0005] Currently, when a fire safety valve is energized and opened, the fire protection system cannot definitively determine whether the valve is currently open or closed. Similarly, even if the fire protection system signals the valve to open, it cannot confirm whether the valve has actually opened. Furthermore, it cannot verify whether the valve has actually closed when instructed to close.

[0006] Existing fire safety valves are merely mechanical parts and cannot be linked with the fire protection system of energy storage devices (too mechanical and not intelligent enough). Utility Model Content

[0007] In view of the problems existing in the prior art, this utility model provides a fire safety valve for external use of energy storage equipment to solve the problems of at least one of the above-mentioned technologies.

[0008] The technical solution of this utility model is: a fire safety valve for external use of energy storage equipment, comprising a safety valve body, characterized in that the safety valve body includes a base, two brackets are mounted on the base, the bottom of the brackets are screwed to both ends of the base, an electric actuator is mounted on the front side of the bracket, the bracket has mounting holes for fixing the electric actuator, and the electric actuator is screwed to the bracket by screws and nuts, an adapter plate is connected below the electric actuator, the adapter plate is screwed to the electric actuator by screws, and a top cover is connected below the adapter plate;

[0009] The base has a circular hole on its edge, a magnetic switch is installed in the circular hole, and structural adhesive is injected at the connection between the circular hole and the magnetic switch.

[0010] A PCB board bracket is installed on the rear side of the bracket by screws. A PCB control board is installed on the PCB board bracket. A shielding cover is covered on the outside of the PCB control board. The shielding cover is connected to the PCB board bracket. Wires are inserted into the PCB control board and the electric push rod, respectively. The wires on the electric push rod are inserted into the PCB control board.

[0011] This invention uses a PCB control board to control the opening and closing of the top cover; it has a simple structure and automates the operation of the exhaust valve. The control board program controls the movement of the electric push rod, which is connected to the top cover via an adapter plate, converting the force of the electric push rod into the opening and closing of the top cover. Furthermore, it provides real-time feedback on whether the valve cover is open or closed.

[0012] Preferably, the surface of the shielding cover has an opening for the wire to enter and exit.

[0013] It allows for easy insertion and removal of cables without affecting the normal use of the shielding cover.

[0014] Further preferably, an inner sealing ring is provided at the connection between the upper cover and the base.

[0015] It can improve the overall sealing effect.

[0016] More preferably, the two ends of the PCB board bracket are respectively connected to the brackets located at both ends of the base, and the top height of the PCB board bracket is lower than the top height of the bracket.

[0017] To prevent excessive height from affecting the connection of the wiring harness.

[0018] Further preferably, the mounting direction of the shielding cover is perpendicular to the mounting direction of the PCB board bracket.

[0019] It can prevent the shielding cover from falling off.

[0020] In a further preferred embodiment, the upper cover has a blind hole corresponding to the magnetic switch, a magnet is embedded in the blind hole, and structural adhesive is injected into the blind hole.

[0021] When the valve is closed, the magnetic switch and the magnet are in contact, and the signal is transmitted to the energy storage cabinet's fire protection system, indicating that the valve is in the closed state. When the valve is open, the magnet moves away from the magnetic switch, and the switch transmits a signal that the valve is open to the energy storage cabinet's fire protection system, preventing the valve from receiving an open signal.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figures 1-7As shown, a fire safety valve for use outside an energy storage device includes a safety valve body. The safety valve body includes a base 1, on which two brackets 2 are mounted. The bottom of the brackets is screwed to both ends of the base. An electric actuator 3 is mounted on the front side of the bracket. The bracket has mounting holes for fixing the electric actuator, and the electric actuator is screwed to the bracket with screws and nuts. An adapter plate 4 is connected to the lower part of the electric actuator, and the adapter plate is screwed to the electric actuator. A top cover 9 is connected to the lower part of the adapter plate. A circular hole is opened on the edge of the base, and a magnetic switch 5 is installed in the circular hole. Structural adhesive is injected at the connection between the circular hole and the magnetic switch. A PCB board bracket 6 is mounted on the rear side of the bracket with screws. A PCB control board 10 is mounted on the PCB board bracket. A shielding cover 7 covers the outside of the PCB control board and is connected to the PCB board bracket. Wires 8 are inserted into the PCB control board and the electric actuator, respectively, and the wires on the electric actuator are inserted into the PCB control board.

[0032] This invention uses a PCB control board to control the opening and closing of the top cover; it has a simple structure and automates the operation of the exhaust valve. The control board program controls the movement of the electric push rod, which is connected to the top cover via an adapter plate, converting the force of the electric push rod into the opening and closing of the top cover. Furthermore, it provides real-time feedback on whether the valve cover is open or closed.

[0033] Further preferably, the surface of the shielding cover has openings for wire entry and exit. This facilitates the insertion and exit of wires without affecting the normal use of the shielding cover.

[0034] Further optimization involves providing an inner sealing ring 11 at the connection between the top cover and the base. This enhances the overall sealing effect.

[0035] Further optimized, the two ends of the PCB board bracket are respectively connected to the brackets located at both ends of the base, and the top height of the PCB board bracket is lower than the top height of the bracket. This prevents excessive height from affecting the insertion of the wiring harness.

[0036] Further optimization involves mounting the shielding cover perpendicular to the mounting direction of the PCB board support. This prevents the shielding cover from falling off.

[0037] In a further preferred embodiment, the upper cover has a blind hole corresponding to the magnetic switch, a magnet is embedded in the blind hole, and structural adhesive is injected into the blind hole.

[0038] When the valve is closed, the magnetic switch and the magnet are in contact, and the signal is transmitted to the energy storage cabinet's fire protection system, indicating that the valve is in the closed state. When the valve is open, the magnet moves away from the magnetic switch, and the switch transmits a signal that the valve is open to the energy storage cabinet's fire protection system, preventing the valve from receiving an open signal.

[0039] Beneficial effects:

[0040] 1. Assembly structure for controlling the opening and closing of the exhaust valve cover: This includes the coordination of a series of parts, such as the control board controlling the movement of the electric push rod, the connection between the push rod and the cover adapter plate, the connection method between the PCB control board and the valve, and the connection between the cover adapter plate and the cover, to ultimately achieve the technical solution of opening and closing the cover.

[0041] 2. When the valve is closed, the magnetic switch and the magnet are in contact, and the signal is transmitted to the energy storage cabinet fire protection system, indicating that the valve is closed. When the valve is open, the magnet moves away from the magnetic switch, and the switch transmits the signal that the valve is open to the energy storage cabinet fire protection system. This prevents the valve from receiving the open signal. If the valve is not open due to various objective reasons, the fire protection system may mistakenly believe that the valve is open, leading to misjudgment and various unpredictable consequences.

[0042] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
