[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0030] Example 1
[0031] This embodiment discloses an industrial and commercial energy storage combustible gas dilution device, the structure of which is as follows: Figure 1-3 The main structure includes: a fixed base 10, a sealing cover 11, an electric propulsion mechanism 3, a low-pressure axial flow fan 1 and a control panel 6;
[0032] The fixed base 10 serves as a structural support for the installation of the electric propulsion mechanism 3 and the low-pressure axial flow fan 1;
[0033] In addition, an air inlet and outlet are opened in the middle position of the fixed base 10, and the sealing cover 11 is matched with the air inlet and outlet. In the covered state, the sealing cover 11 can fit flush with the air inlet and outlet holes in the middle of the fixed base 10, thereby realizing the opening and closing of the combustible gas dilution device through the cooperation between the sealing cover 11 and the air inlet and outlet on the fixed base 10.
[0034] Preferably, an outer ring groove structure is formed on the back of the fixed base where the air inlet and outlet are located. The outer ring grooves are distributed around the air inlet and outlet. A sealing ring 12 is installed on the back of the fixed base near the outer ring groove. When the combustible gas dilution device is installed in the energy storage cabinet, the sealing ring groove 12 is sealed against the cabinet, preventing the ingress of rainwater.
[0035] For the sealing cover 11, the driving power for its opening and closing actions is provided by the electric propulsion mechanism 3. The electric propulsion mechanism 3 is in the form of a cylinder and is fixed at the middle position of the air inlet and outlet of the fixed base 10 through a mounting frame, and the output end of the electric propulsion mechanism 3 is connected to the sealing cover 11.
[0036] The mounting bracket is horizontally arranged at the location of the air inlet and outlet so as not to affect the air inlet and outlet operation of the air inlet and outlet.
[0037] Preferably, to improve the stability of the opening and closing of the sealing cover plate 11, a guide structure is provided. Guide posts 4 are connected and installed on both sides of the back of the sealing cover plate 11. The guide posts 4 pass through the guide post holes in the fixed base 10. Guide springs 5 are mounted on the guide posts 4. The guide springs 5 are limited between the baffle at the axial end of the guide posts 4 and the fixed base 10. Thus, under the action of the guide posts 4 and the guide springs 5, the electric propulsion mechanism 3 drives the sealing cover plate 11, so that the sealing cover plate 11 can complete the opening and closing actions more smoothly under the guidance of the guide posts 4.
[0038] The combustible gas dilution device also incorporates a low-pressure axial flow fan 11, which acts as a fan to accelerate gas flow. To facilitate installation of the entire combustible gas dilution device within the energy storage cabinet, the fan support rods 2 are used to assemble and connect the low-pressure axial flow fan 1 to the fixed base 10.
[0039] Preferably, there are four groups of fan support rods 2, one end of the fan support rod 2 is fixedly connected to the back of the fixed base 10, and the other end is adapted and assembled with the mounting hole opened on the fan casing of the low-pressure axial flow fan 1.
[0040] In addition, in order to realize the startup control of the low-pressure axial flow fan 1 and the electric propulsion mechanism 3 , the industrial and commercial energy storage combustible gas dilution device also includes a control panel 6 and is equipped with a combustible gas composite detector 13 .
[0041] The control board 6 is installed on one side of the casing of the electric propulsion mechanism 3 through a machine box or other similar structures, and the power supply terminal 7, the control signal terminal 8, and the feedback signal terminal 9 are led out from the control board.
[0042] The power supply terminal 7 is used to connect to the power supply to provide power to the combustible gas dilution device. The control signal terminal 8 is connected to the combustible gas composite detector 13, and the feedback signal terminal 9 is connected to the electric propulsion mechanism 3 and the low-pressure axial flow fan 1.
[0043] The combustible gas composite detector is a commercially available finished product used for combustible gas detection. The number of combustible gas composite detectors required is determined by the energy storage cabinet's installation requirements. When the combustible gas composite detector detects an excessive concentration of combustible gas, it transmits a feedback signal via feedback signal terminal 9 to the control board 6. The control board 6 performs a logical analysis and sends a command via control signal terminal 8 to the electric propulsion mechanism 3 and low-pressure axial flow fan 1 to activate them.
[0044] Example 2
[0045] This embodiment discloses an industrial and commercial energy storage cabinet, which is provided with the industrial and commercial energy storage combustible gas dilution device disclosed in the first embodiment and the equipped combustible gas composite detector 13.
[0046] like Figure 6 As shown, the setting method is as follows: an air inlet mounting hole and an air outlet mounting hole are respectively opened on the cabinet of the energy storage cabinet; the industrial and commercial energy storage combustible gas dilution device is installed at the air inlet mounting hole and the air outlet mounting hole of the energy storage cabinet through a fixed base 10, and the sealing ring groove 12 is fit and sealed with the cabinet; the combustible gas composite detector 13 is placed in the battery room of the energy storage cabinet.
[0047] The combustible gas dilution device installed at the air inlet mounting hole is used as an air inlet device, and the combustible gas dilution device installed at the air outlet mounting hole is used as an air outlet device. The air inlet device and the air outlet device are connected to the same combustible gas composite detector 13 so that the air inlet device and the air outlet device keep working synchronously.
[0048] Therefore, the working process of the energy storage cabinet using the combustible gas dilution device to dilute the gas in the battery room is as follows:
[0049] When the combustible gas composite detector 13 detects that the concentration of combustible gas in the battery room exceeds the standard, the feedback signal is transmitted to the control board 6 through the feedback signal terminal 9. The control board 6 performs a logical analysis and sends a command to the electric propulsion mechanism 3 and the low-pressure axial flow fan 1 through the control signal terminal 8. The electric propulsion mechanism 3 pushes the sealing cover plate 11 along the guide column 4 to open it, and starts the low-pressure axial flow fan 1 at the same time (the schematic diagram of the open state of the combustible gas dilution device is shown in FIG). Figure 4 External air enters the battery room from the combustible gas dilution device used as an air inlet device, and the air containing combustible gas in the battery room is discharged from the combustible gas dilution device used as an air outlet device, thereby rapidly reducing the concentration of combustible gas in the battery room.
[0050] Similarly, as the concentration of combustible gas in the battery room decreases, the combustible gas composite detector 13 detects that the gas concentration in the battery room returns to normal, and then the combustible gas dilution device can be closed. The closed state diagram of the combustible gas dilution device is shown in FIG. Figure 5 shown.
[0051] In summary, the industrial and commercial energy storage combustible gas dilution device and energy storage cabinet disclosed in this invention have the following technical advantages:
[0052] In order to achieve extremely early prevention of fire and prevent the expansion of fire accidents, the energy storage cabinet is equipped with a combustible gas composite detector and an air inlet and outlet device. This industrial and commercial energy storage combustible gas dilution device is equipped with a gas composite detector and an air inlet and outlet device. When the gas composite detector detects that the combustible gas reaches a certain threshold, the air inlet and outlet devices are started, and the outside air enters the battery room, and the combustible gas inside the battery room is discharged, so that the combustible gas concentration in the battery room is rapidly reduced. The dangerous source is detected at the extremely early stage of the fire and the fire source is eliminated, ensuring the safe operation of the energy storage system.
[0053] It adopts a low-pressure axial flow fan + propulsion mechanism to drive the sealing cover to open and close. It has a simple structure, compact size, can be opened and closed automatically, and is integrated with the energy storage cabinet, which is beautiful and elegant. Since the traditional fan + electric shutter design is cancelled, this industrial and commercial energy storage combustible gas dilution device is more suitable for small industrial and commercial cabinets.
[0054] The above-mentioned implementation manner is not a limitation of the present invention, and the present invention is not limited to the above-mentioned examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
