Description

Technical Field

[0001] This application relates to the field of louver technology, and in particular to an automatic dust removal louver and an energy storage cabinet. Background Technology

[0002] The electrical compartment of an industrial and commercial energy storage cabinet (hereinafter referred to as the energy storage cabinet) needs to be cooled by a fan. Generally, air is drawn in through the louvers of the front door and exhausted through the louvers of the rear door. Since energy storage cabinets are mostly placed outdoors, in industrial parks with a lot of dust, a filter cotton needs to be installed in the louver assembly of the front door.

[0003] To ensure smooth air intake and effective filtration, the filter cotton needs to be replaced regularly. In general environments, the filter cotton in energy storage cabinets needs to be replaced every three months. In harsh environments, such as foundries, cement plants, and paint shops, the filter cotton needs to be replaced monthly. Each filter cotton replacement requires maintenance personnel to go to the site, open the front door, remove the screws on the louvers, insert new filter cotton, and then tighten the screws back on. This entire process causes the energy storage cabinet to be shut down for at least 10 minutes. Because energy storage cabinet projects are geographically dispersed and numerous, such a high maintenance frequency will significantly increase the workload of maintenance personnel. Inadequate maintenance will negatively impact the economic efficiency of the energy storage cabinet.

[0004] Therefore, in view of the above-mentioned technical problems, how to avoid frequent replacement of the filter cotton of the blinds is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide an automatic dust removal louver and energy storage cabinet that uses the impact generated by the release of high air pressure to remove dust from the filter cotton, thus eliminating the need to replace the filter cotton.

[0006] To achieve the above objectives, this application provides an automatic dust removal louver, comprising:

[0007] Venetian blind body;

[0008] Filter cotton is provided on the louver body to filter the air flowing through the louver body;

[0009] The dust removal device includes a cavity located on the air outlet side of the louver body and an air source assembly communicating with the cavity. The cavity has an opening on a first side facing the filter cotton to allow air to enter and exit the cavity through the opening. The second side of the cavity is openable and closable. In a first state, the air in the cavity is discharged from the second side of the cavity. In a second state, the air source assembly is used to introduce high-pressure gas into the cavity, and the high-pressure gas in the cavity is discharged from the first side of the cavity.

[0010] Preferably, the cavity includes a frame serving as a side cavity wall, the frame being fixedly mounted on the louver body, the frame enclosing a structure with openings on both sides and a hollow interior; the cavity also includes blades serving as a second side cavity wall, the blades being movably mounted on the frame to open and close the second side of the cavity.

[0011] Preferably, the dust removal device further includes a drive component disposed on the cabinet door or the louver body, the actuating end of the drive component being connected to the blade to drive the blade to open and close the second side of the cavity.

[0012] Preferably, there are multiple blades, which are arranged in parallel on the frame along a preset direction. The blades are rotatably mounted on the frame around a fixed axis. The multiple blades are synchronously connected by a linkage, and the actuating end of the drive member is rotatably connected to at least one blade.

[0013] In the first state, the planes on which the multiple blades are located are parallel to each other, and adjacent blades are spaced apart to open the second side of the cavity;

[0014] In the second state, the planes on which the multiple blades are located are in the same plane, and the sides of adjacent blades abut against each other to cover and seal the second side of the cavity.

[0015] Preferably, the driving component includes a drive motor, and the output shaft of the drive motor is coaxially connected to the blade via a coupling.

[0016] Preferably, the frame has several pin holes on both sides, and the rotating shafts at both ends of the blade are rotatably connected to the pin holes. The linkage includes a linkage plate, which is located on both sides of the blade, and the linkage plate on each side is hinged to the blade.

[0017] Preferably, the gas source assembly includes an electric air pump, a gas storage cylinder, a solenoid valve, an air pipe, and several connectors. The electric air pump is connected to the gas storage cylinder via a three-way connector, and the three-way connector is connected to the cavity via the air pipe. The solenoid valve is installed on the air pipe and is used to control whether to supply air to the cavity.

[0018] Preferably, the trachea is connected to the frame via a plurality of the connectors, and the connectors are in communication with the cavity.

[0019] Preferably, the electric air pump is fixed in the cabinet by an air pump mounting bracket, and the gas storage cylinder is fixed in the cabinet by a gas cylinder mounting bracket.

[0020] An energy storage cabinet includes a cabinet body and a cabinet door provided on the cabinet body. The air inlet and outlet of the cabinet door are provided with louvers, and the louvers are the automatic dust removal louvers described above.

[0021] Compared to the aforementioned background technology, this application provides a cavity structure on the air outlet side of the louver body. In the first state, the second side of the cavity is open, allowing the louver body to vent air normally, and the filter cotton on the louver body can filter impurities in the air. In the second state, the second side of the cavity is closed, blocking the air outlet path of the louver body. In this case, high-pressure gas is introduced into the cavity using an air source component. The high-pressure gas in the cavity can be vented to the filter cotton through the first side of the cavity, thereby loosening and blowing away the dust attached to the filter cotton, achieving a cleaning effect, greatly reducing the frequency of filter cotton replacement, and even eliminating the need to replace the filter cotton.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 5 As shown, in this embodiment, an automatic dust removal louver is provided. The louver includes a louver body 1, a filter cotton 4, and a dust removal device. The louver body 1 is fixed to the air inlet of the cabinet door 13, and the louver body 1 allows air circulation. Of course, the louver body 1 can also be set at the air outlet on the rear side of the cabinet 14. No further restrictions are imposed here.

[0034] The filter cotton 4 is installed on the louver body 1. When air flows through the louver body 1, the filter cotton 4 can filter impurities in the air and ensure the air quality entering the cabinet 14.

[0035] The dust removal device includes a cavity located on the air outlet side of the louver body 1 and an air source component communicating with the cavity. The cavity has an opening on the first side facing the filter cotton 4, allowing air to first enter the cavity after passing through the filter cotton 4; similarly, the air inside the cavity can also be discharged outwards after passing through the filter cotton 4. It should be noted that the shape of the cavity is not strictly limited here; different shapes can be selected according to actual needs, as long as it ensures that the air passing through the filter cotton 4 can enter the cavity.

[0036] Furthermore, the second side of the cavity can be opened and closed. The first and second sides of the cavity can be opposite sides or non-opposite sides; no further restrictions are imposed here, and both fall within the scope of protection of this application. When the second side of the cavity is in the first state, that is, the second side of the cavity is in the open state, the air inside the cavity is discharged from the second side of the cavity. The air movement path is outside the cabinet - louver body 1 - filter cotton 4 - cavity - inside the cabinet. At this time, the filter cotton 4 can filter impurities in the air normally. If the first and second sides of the cavity are set to be opposite sides, the air flow efficiency can be guaranteed.

[0037] When the second side of the cavity is in the second state, that is, the second side of the cavity is in the closed state, the air outside the cabinet cannot enter the cabinet because the air outlet side of the louver cannot be supplied with airflow. At the same time, high-pressure gas is introduced into the cavity using the air source component. The flow path of the high-pressure gas is cavity - filter cotton 4 - louver body 1 - outside the cabinet. It can be seen that in the second state, the high-pressure gas in the cavity will be discharged to the outside of the cabinet after flowing through the filter cotton 4. The impact generated by the high-pressure gas removes the dust on the filter cotton 4 and blows the dust to the outside of the cabinet, thus completing the cleaning of the filter cotton 4.

[0038] In summary, this application provides a cavity structure on the air outlet side of the louver body 1. In the first state, the second side of the cavity is open, allowing the louver body 1 to vent air normally, and the filter cotton 4 on the louver body 1 can filter impurities in the air. In the second state, the second side of the cavity is closed, blocking the air outlet path of the louver body 1. In this case, high-pressure gas is introduced into the cavity using an air source component. The high-pressure gas in the cavity can be vented to the filter cotton 4 through the first side of the cavity, thereby loosening and blowing away the dust attached to the filter cotton 4, achieving a cleaning effect, greatly reducing the frequency of replacing the filter cotton 4, and even eliminating the need to replace the filter cotton 4.

[0039] In some embodiments, a frame 2 can be fixedly installed on the air outlet side of the louver body 1. The frame 2 serves as the side cavity wall of the aforementioned cavity, and the frame 2 encloses a structure with openings on both sides and a hollow interior. Please refer to... Figure 1 and Figure 3 Meanwhile, the frame 2 is also located on the outer periphery of the air outlet of the louver body 1, ensuring that the air filtered by the filter cotton 4 can enter the area enclosed by the frame 2. The cavity also includes blades 3 as the cavity wall on its second side. The blades 3 are movably mounted on the frame 2. Through the cooperation between the movable blades 3 and the frame 2, the second side of the cavity can be opened and closed.

[0040] Specifically, the blade 3 can be rotatably mounted on the frame 2. The rotation of the blade 3 allows it to cover and press against the frame 2, or creates a gap between the blade 3 and the frame 2, thus opening and closing the second side of the cavity. Alternatively, the blade 3 can be mounted on the frame 2 via linear reciprocating motion. This movement allows for misalignment between the blade 3 and the frame 2, or for the blade 3 to cover the frame 2, achieving the same purpose as opening and closing the second side of the cavity. Other forms of blade 3 opening and closing the second side of the cavity are not detailed here, but all fall within the scope of this application.

[0041] The dust removal device also includes a drive unit 6 mounted on the cabinet door 13 or the louver body 1, please refer to Figure 1 The actuating end of the drive unit 6 is connected to the blade 3, thereby driving the blade 3 to open and close the second side of the cavity. When the blade 3 is rotated, the drive unit 6 can be a stepper motor, servo motor, etc.; when the blade 3 is linearly reciprocating, the drive unit 6 can be a power cylinder, linear motor, etc., which will not be described in detail here.

[0042] In this embodiment, the rotation of blade 3 is used as an example for detailed description. Specifically, there are multiple blades 3. Please refer to [reference needed]. Figure 4 and Figure 5 Multiple blades 3 are arranged parallel to each other on the frame 2 along a preset direction, which can be vertical or horizontal. Each blade 3 is rotatably mounted on the frame 2 around a corresponding fixed axis, thereby achieving a rotatable connection between the multiple blades 3 and the frame 2. In addition, the multiple blades 3 can rotate synchronously through the linkage 5, and the actuating end of the drive component 6 is rotatably connected to one blade 3, so that each blade 3 can be driven to rotate simultaneously, thereby opening and closing the second side of the cavity.

[0043] In the first state described above, the planes on which the multiple blades 3 are located are parallel to each other, and there is a gap between adjacent blades 3, so that the second side of the cavity is in the open state; in the second state described above, the plane on which the blades 3 are located will gradually rotate to be parallel to and fit against the end face of the frame 2. At this time, the planes on which the multiple blades 3 are located are in the same plane, that is, the plane on which the blades 3 are located coincides with the end face of the frame 2, so that the multiple blades 3 can jointly cover and seal the second side of the cavity.

[0044] Of course, blade 3 can also be a whole sheet structure, and the opening and closing of the second side of the cavity can be achieved by rotating the entire blade 3.

[0045] Based on the rotation setting of blade 3, the driving component 6 is a drive motor. The output shaft of the drive motor is coaxially connected to blade 3 through coupling 11, thereby driving multiple blades 3 to rotate synchronously.

[0046] Please refer to Figure 2Several pin holes 12 are provided on both sides of the frame 2. The rotating shafts at both ends of each blade 3 are inserted into the pin holes 12, thereby realizing the rotational connection between the blade 3 and the frame 2. The linkage 5 includes a linkage plate, which is located on both sides of the blade 3. Each linkage plate can be hinged to multiple blades 3 at the same time, so that each blade 3 can rotate synchronously under the linkage action of the linkage plate.

[0047] The gas supply components include an electric air pump 9, an air cylinder 10, a solenoid valve 8, air tubing, and several connectors 7, etc. Please refer to [reference needed]. Figure 1 The connector 7 includes a three-way connector, an L-shaped connector, etc. The electric air pump 9 and the air storage cylinder 10 are respectively connected to the two connecting ends of the three-way connector through air pipes. The third connecting end of the three-way connector is connected to a solenoid valve 8. The other end of the solenoid valve 8 is connected to the cavity through an air pipe.

[0048] The air pipe from the solenoid valve 8 is connected to the frame 2 through a three-way connector and an L-shaped connector. The L-shaped connector is located at the end of the air pipe, and both the three-way connector and the L-shaped structure are connected to the cavity, thereby allowing high-pressure gas to be introduced into the cavity.

[0049] The louver assembly of this application is installed at the air inlet of the cabinet door 13 and fixed with nuts; the frame 2 is set on the louver assembly and fixed with screws; the electric air pump 9 is set on the side wall of the cabinet 14 and fixed with an air pump fixing bracket; the air storage cylinder 10 is set on the side wall of the cabinet 14 and fixed with an air cylinder fixing bracket.

[0050] Furthermore, the louvers of this application are equipped with a control system, which includes a control unit programmed with a control program. The control unit can be connected to the drive unit 6, the electric air pump 9, and the solenoid valve 8. By programming a time-period control signal into the control unit, the time period is set by the operator based on the actual usage of the filter cotton 4. After one time period, the drive unit 6 automatically starts, rotating the blades 3 and closing the second side of the cavity. At this time, the control unit controls the solenoid valve 8 to open, allowing high-pressure gas from the gas cylinder 10 to enter the cavity, thus cleaning the filter cotton 4. During the aforementioned time period, the blades 3 are in the open position, allowing normal air exchange between the inside and outside of the cabinet.

[0051] Furthermore, when the filter cotton 4 needs cleaning, the control unit controls the electric air pump 9 to operate. At this time, the solenoid valve 8 is in the closed state, and gas enters the gas storage cylinder 10. The electric air pump 9 has a built-in pressure measurement function. When the pressure in the gas storage cylinder 10 reaches the program-set upper limit, it stops operating. Then, the control unit controls the drive component 6 to start operating, driving the blade 3 to rotate downwards by 90° until the second side of the cavity is completely closed. Please refer to [reference needed]. Figure 5At this point, a relatively sealed space is formed inside the cavity, allowing exhaust to flow smoothly only towards the filter cotton 4. Then, the control unit opens the solenoid valve 8, allowing high-pressure gas from the gas cylinder 10 to enter the cavity through the air pipe. The release of the high-pressure gas generates a powerful impact, loosening and blowing away the dust adhering to the filter cotton 4, thus achieving a cleaning effect. The control unit is set with a five-second delay to ensure complete release of the high-pressure gas, and then controls the drive component 6 to rotate in reverse, causing the blade 3 to rotate upwards by 90° until fully open. Please refer to [reference needed]. Figure 4 .

[0052] The louvers in this application have an automatic dust removal function. A dust removal device has been added to the original louvers, which can clean the filter cotton 4 regularly without replacing it. Furthermore, the cabinet door 13 does not need to be opened during the dust removal process, and the energy storage cabinet will not stop working, thus improving the operating efficiency of the energy storage cabinet.

[0053] This application also provides an energy storage cabinet, please refer to... Figure 6 The energy storage cabinet includes a cabinet body 14 and a cabinet door 13 on the cabinet body 14. The air inlet and outlet of the cabinet door 13 are provided with louvers, which are the aforementioned automatic dust removal louvers.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
