Description

Technical Field

[0001] The invention relates to a fire safety valve, in particular to an electric cam structure fire safety valve for energy storage equipment. Background Art

[0002] At present, the centralized monitoring system, battery management system, and thermal management system of new energy storage equipment are widely used in 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 a strong application prospect in solving the imbalance between electricity supply and demand and improving energy utilization efficiency. Industrial and commercial energy storage cabinets store excess electricity when storing electricity in battery packs. During the storage and discharge process, a certain amount of heat will be generated, or the failure of the battery cell will generate a lot of heat, which will cause the pressure difference between the inside and outside of the industrial and commercial energy storage cabinet to lose balance, which will cause safety hazards, because the gas after failure needs to be discharged. In order to meet the safe and stable operation of the energy storage equipment, each device needs to be installed with a fire safety valve.

[0004] The function of the fire safety valve is to prevent water and exhaust. When the humidity and pressure inside the cavity suddenly rise due to a short circuit or other faults, and the pressure is too high and exceeds the safety value, the pressure relief valve will be opened to quickly balance the pressure and deal with the extreme pressure.

[0005] The existing fire safety exhaust valve cannot automatically reset and close the exhaust valve after being powered on and opened, and needs to be closed manually, which is troublesome and inefficient. Summary of the invention

[0006] In view of the problems existing in the prior art, the present invention provides an electric cam structure fire safety valve for energy storage equipment, which controls the operation of the motor through the program of the control panel combined with the spring on the guide shaft to drive the cam to control the opening and closing of the upper cover; the structure is simple to realize the automatic operation of the fire safety valve, and the opening and closing signals can be fed back to the energy storage device in real time.

[0007] The technical solution of the present invention is: an electric cam structure fire safety valve for energy storage equipment, comprising an upper cover assembly, a motor assembly, a base assembly, a control panel assembly and a fan;

[0008] The upper cover assembly comprises an upper cover, a bearing bracket, a bearing and a plurality of guide shafts; the bearing is mounted on the bearing bracket, and the bearing bracket is fixed to the middle part of the bottom surface of the upper cover; the plurality of guide shafts are perpendicular to the bottom surface of the upper cover and fixedly connected to the bottom surface of the upper cover;

[0009] The motor assembly comprises a motor, a motor bracket and a cam, wherein the motor is mounted on the motor bracket, and the cam is mounted on the rotating shaft of the motor and can rotate with the rotating shaft of the motor;

[0010] The base assembly includes a base, a switch, a plurality of springs and a plurality of nylon lock nuts; the switch is fixed on the base; the base is also provided with a plurality of guide shaft through holes, and the plurality of guide shafts pass through the corresponding guide shaft through holes one by one and are fixed by corresponding nylon lock nuts after being covered with corresponding springs; the motor assembly is fixed on the base through a motor bracket, so that the cam of the motor assembly contacts the bearing of the upper cover assembly;

[0011] The fan is fixed to the back of the base by means of hexagonal studs and screws;

[0012] The control panel assembly is fixed on the base, and the control panel assembly is electrically connected to the fan, the motor and the switch;

[0013] When the energy storage device needs to open the fire safety valve, the host of the energy storage device sends a signal to the control panel assembly of the fire safety valve. The control panel assembly drives the motor to operate according to the pre-set program. The motor drives the cam locked on the motor to rotate 90 degrees. The cam rotates and contacts the bearing locked on the upper cover assembly. Because the upper cover assembly has a guide shaft and the base has a guiding function, the cam pushes the bearing to rotate and squeezes the upper cover assembly in the vertical direction. After reaching 90 degrees, the motor will stop rotating and start self-locking, so as to achieve the purpose of opening the fire safety valve for exhaust. The fan will start to operate and exhaust synchronously. At this time, the switch installed on the base assembly will transmit a signal to the control panel assembly because it is activated by the opening of the upper cover. The control panel assembly will synchronize the information that it has been opened to the energy storage device, and the fire safety valve is currently in an open state.

[0014] When the fire safety valve needs to be closed when it is open, the host of the energy storage device sends a signal to the control panel assembly of the fire safety valve. The control panel assembly drives the motor to rotate in the opposite direction according to the pre-set program. The motor drives the cam locked on the motor to rotate 90 degrees in the opposite direction. The cam rotates and reduces the contact with the bearing locked on the upper cover assembly. When there is no contact at all, the motor self-locks. During this process, the upper cover assembly is pulled back by the rebound force of the spring on the base.

[0015] Furthermore, the base assembly further includes an inner sealing ring and an outer sealing ring, which are respectively sleeved on the inner and outer surfaces of the base. When the spring rebound force on the base pulls the upper cover assembly back, the upper cover presses the sealing ring on the base assembly, and the holding force of the spring satisfies the waterproof and dustproof performance.

[0016] Furthermore, the control board assembly includes a mainboard bracket, a control board, a light guide column and a mainboard cover; the control board is first screwed to the mainboard bracket, the light guide column is screwed into the corresponding position of the mainboard cover, and then the mainboard cover and the mainboard bracket are screwed together.

[0017] The beneficial effects of the present invention are: providing an electric cam structure fire safety valve for energy storage equipment, which controls the operation of the motor through the program of the control panel combined with the spring on the guide shaft to drive the cam to control the opening and closing of the upper cover; the structure is simple to realize the automatic operation of the fire safety valve, and the opening and closing signals can be fed back to the energy storage cabinet in real time.

[0034] An electric cam structure fire safety valve for energy storage equipment comprises an upper cover assembly 1, a motor assembly, a base assembly 2, a control panel assembly 6 and a fan 7.

[0035] The upper cover assembly 1 includes an upper cover 12, a bearing bracket 13, a bearing 14 and a plurality of guide shafts 15. The bearing 14 is mounted on the bearing bracket 13, and the bearing bracket 13 is fixed to the middle part of the bottom surface of the upper cover 12. The plurality of guide shafts 15 are perpendicular to the bottom surface of the upper cover 12 and fixedly connected to the bottom surface of the upper cover 12.

[0036] The motor assembly includes a motor 10, a motor bracket 20 and a cam 11. The motor 10 is mounted on the motor bracket 20, and the cam 11 is mounted on the rotating shaft of the motor 10 and can rotate with the rotating shaft of the motor.

[0037] The base assembly 2 includes a base 19, a switch 16, a plurality of springs 3 and a plurality of nylon lock nuts 4. The switch 16 is fixed on the base 19. The base 19 is also provided with a plurality of guide shaft through holes, and a plurality of guide shafts 15 pass through the corresponding guide shaft through holes one by one and are covered with corresponding springs 3 and fixed by corresponding nylon lock nuts 4. The motor assembly is fixed on the base 19 through a motor bracket 20, so that the cam 11 of the motor assembly contacts the bearing 14 of the upper cover assembly 1.

[0038] The fan 7 is fixed to the back side of the base 19 by means of hexagonal studs 8 and screws 9 .

[0039] The control board assembly 6 is fixed on the base 19 , and the control board assembly 6 is electrically connected to the fan 7 , the motor 10 and the switch 16 .

[0040] The assembly method is as follows:

[0041] like Figure 1 As shown in the figure, install the bearing bracket into the corresponding position of the upper cover.

[0042] like Figure 2 As shown in the figure, install the bearing sleeve and gasket into the bearing, and then lock the bearing to the bearing bracket with screws and nuts. Figure 3 shown.

[0043] like Figure 4 As shown, first screw the control board to the mainboard bracket with screws, screw the light guide column into the corresponding position of the mainboard cover with screws, and then screw the mainboard cover and the mainboard bracket together with screws.

[0044] like Figure 5 As shown in the figure, screw the switch into the base, screw the motor bracket into the corresponding position of the base with screws, and then install the corresponding inner and outer sealing rings into the corresponding slots of the base. Figure 6 shown.

[0045] like Figure 7 As shown in the figure, screw the motor to the motor bracket, insert the cam sleeve onto the motor shaft, and then install the cam. Figure 8 As shown, the cam is locked onto the cam sleeve by means of screws.

[0046] like Fig. 9 As shown, install the upper cover assembly into the three holes on the base, put springs on the corresponding three guide shafts on the upper cover assembly, press the gasket, and then tighten it with the nylon lock nut. Fig.10 shown.

[0047] like Fig.11 As shown in the figure, screw the control board assembly to the base assembly with screws.

[0048] like Fig.12 As shown in the figure, lock the four hexagonal studs on the base assembly, then align the four holes on the fan with the four holes corresponding to the four hexagonal studs, and use four screws to lock the fan to the hexagonal studs. Fig.13 shown.

[0049] like Fig.14As shown, when the energy storage device needs to open the fire safety valve, the host of the energy storage device sends a signal to the control panel assembly of the fire safety valve. The control panel assembly drives the motor to operate according to the pre-set program. The motor drives the cam locked on the motor to rotate 90 degrees. The cam rotates and contacts the bearing locked on the upper cover assembly. Because the upper cover assembly has a guide shaft and the base has a guiding function, the cam pushes the bearing to rotate and squeezes the upper cover assembly in the vertical direction. After reaching 90 degrees, the motor will stop rotating and start self-locking, so as to achieve the purpose of opening the fire safety valve for exhaust, and the fan will start to operate and exhaust synchronously. At this time, the switch installed on the base assembly will transmit a signal to the control panel assembly because it is activated by the opening of the upper cover. The control panel assembly will synchronously send the information that it has been opened to the energy storage device, and the fire safety valve is currently in an open state.

[0050] When the fire safety valve is in the open state and needs to be closed, the host of the energy storage device sends a signal to the control panel assembly of the fire safety valve. The control panel assembly drives the motor to run in the reverse direction according to the pre-set program. The motor drives the cam locked on the motor to rotate 90 degrees in the opposite direction. The cam rotates and reduces the contact with the bearing locked on the upper cover assembly. When there is no contact at all, the motor self-locks; during this process, the upper cover assembly is pulled back by the rebound force of the spring on the base. When the rebound force of the spring on the base pulls the upper cover assembly back, the upper cover presses the sealing ring on the base assembly, and the retention force of the spring meets the waterproof and dustproof performance.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
