[0003] In the prior art, in order to dissipate the heat in the energy storage device, an air inlet is usually formed on the energy storage device. In order to prevent a large amount of dust from entering the energy storage device through the air inlet, a filter screen is arranged at the air inlet to intercept the dust in the air. The mesh of the filter screen is usually set to be relatively dense to enhance the interception of the dust in the air. Although this method can achieve more effective interception of the dust, the too dense mesh of the filter screen will affect the passage of air, thereby reducing the heat dissipation effect inside the energy storage device. If the mesh of the filter screen is set to be too large, a large amount of dust and impurities will easily enter the energy storage box, so that a large amount of dust is attached to the equipment and electrical elements, thereby affecting the service life of the equipment and electrical elements. CONTENT OF THE INVENTION

[0004] In order to overcome the shortcomings that the mesh of the filter screen is usually set to be relatively dense to enhance the interception of the dust in the air, and although this method can achieve more effective interception of the dust, the too dense mesh of the filter screen will affect the passage of air, the utility provides an energy storage device for source-grid-load-storage.

[0006] As a preferred technical scheme of the utility, a plurality of elastic strips are further included; each electrostatic plate is fixedly connected to a plurality of elastic strips on one side.

[0007] As a preferred technical scheme of the utility model, the elastic strip is arranged in a wave shape.

[0009] As a preferred technical scheme of the utility model, the utility model further comprises a first multi-stage telescopic rod, a second multi-stage telescopic rod, a connecting rod, a torsion spring rod, a cleaning plate, a conveying pipe and a connecting pipe, a plurality of first multi-stage telescopic rods are fixedly connected to the upper parts of the opposite sides of each fixed frame body, a second multi-stage telescopic rod is arranged on the telescopic part of each first multi-stage telescopic rod, a connecting rod is fixedly connected to the telescopic parts of all the second multi-stage telescopic rods, a torsion spring rod is rotatably connected to the upper part and the lower part of each connecting rod, the elastic coefficient of the elastic member is smaller than the elastic coefficient of the torsion spring rod, a cleaning plate is fixedly connected to each torsion spring rod, the cleaning plate is hollow, a conveying pipe is arranged on the fixed part of each second multi-stage telescopic rod, and a plurality of connecting pipes are arranged on each conveying pipe, the connecting pipes are telescopic pipes, and one end of the connecting pipe is connected with the cleaning plate.

[0010] Advantages:

[0011] The external pump machine sends air into the blocking frame strip through the fixing pipe, the blocking frame strip is arranged as an air bag, so that the air forces the blocking frame strip to expand, and the expanded blocking frame strip blocks the gap between the energy storage box and the cabinet door, thereby avoiding the dust and humid air from entering the energy storage box through the gap, and further avoiding the problem of too much dust and humidity on the equipment and electrical components in the energy storage box.

[0012] Since the electrostatic plate is arranged in a wave shape, the air passes through the channel formed between the two adjacent electrostatic plates, so that the electrostatic plate can more fully adsorb the fine dust in the air.

[0013] In this way, the above-mentioned filter screen and electrostatic plate can solve the problem in the prior art that the mesh of the filter screen is usually arranged to be dense to enhance the interception of dust in the air, which can effectively intercept the dust, but the too dense mesh of the filter screen affects the air passing through, thereby reducing the heat dissipation effect inside the energy storage box, and if the mesh of the filter screen is arranged to be too large, a large amount of dust and impurities can easily enter the energy storage box, so that a large amount of dust is attached to the equipment and electrical components, thereby affecting the service life of the equipment and electrical components.

DETAILED DESCRIPTION

[0023] The utility model is described in detail below in combination with the drawings and specific embodiments, but not as the limitation of the utility model.

[0024] Example 1

[0025] It also includes fixed frame 4, filter screen 5, static plate 6, composite moisture absorbing cotton 7 and elastic element 8; The front side and the rear side of the energy storage box body 1 are fixedly connected and communicated with a fixed frame 4; Each fixed frame 4 is installed with a filter screen 5; The inner side of each fixed frame 4 is slidably connected with at least eight static plates 6 distributed equidistantly upward and downward; The upper side and the lower side of each static plate 6 are installed with two composite moisture absorbing cottons 7 distributed equidistantly forward and backward; Each static plate 6 is fixedly connected with four elastic elements 8 distributed in a matrix, and one end of the elastic element 8 is fixedly connected with the fixed frame 4.

[0026] The elastic strip 9 is arranged in a wave shape.

[0027] It also includes blocking frame strip 21 and fixed pipe 22; The right part of the inner side of the energy storage box body 1 is installed with a blocking frame strip 21, and the blocking frame strip 21 is an air bag; The fixed pipe 22 is fixedly connected and communicated with the blocking frame strip 21.

[0028] It also includes first multi-stage telescopic rod 31, second multi-stage telescopic rod 32, connecting rod 33, torsion spring rod 34, cleaning plate 35, conveying pipe 36 and connecting pipe 37; The upper part of the opposite side of each fixed frame 4 is bolted with two first multi-stage telescopic rods 31 distributed equidistantly left and right; The telescopic part of each first multi-stage telescopic rod 31 is installed with a second multi-stage telescopic rod 32; The telescopic part of each second multi-stage telescopic rod 32 is fixedly connected with a connecting rod 33; The upper part and the lower part of each connecting rod 33 are rotatably connected with a torsion spring rod 34, and the elastic coefficient of the elastic element 8 is much smaller than the elastic coefficient of the torsion spring rod 34; The upper part of each torsion spring rod 34 is fixedly connected with a cleaning plate 35, and the inside of the cleaning plate 35 is hollow for the passage of air; The fixed part of each second multi-stage telescopic rod 32 is installed with a conveying pipe 36; The upper part of each conveying pipe 36 is fixedly connected and communicated with two connecting pipes 37 distributed upward and downward, and the connecting pipe 37 is a telescopic pipe, and one end of the connecting pipe 37 is communicated with the cleaning plate 35.

[0029] When using the energy storage device, first, the fixed pipe 22 and the conveying pipe 36 are docked with the external pump, then when the equipment and electrical elements in the energy storage box body 1 work, the heat dissipation fan 3 is controlled to dissipate heat inside the energy storage box body 1, so as to avoid overheating of the equipment and electrical elements, and affect the normal operation of the equipment and electrical elements, and the heat will be discharged outward through the fixed frame 4;

[0030] It should be noted that, since the energy storage box 1 is placed outdoors, therefore, whenever the staff checks the equipment and electrical components in the energy storage box 1 and closes the cabinet door 2, the control external pump machine transports air into the blocking frame strip 21 through the fixed pipe 22, since the blocking frame strip 21 is provided as an air bag, so the air will force the blocking frame strip 21 to expand, and the expanded blocking frame strip 21 will block the gap between the energy storage box 1 and the cabinet door 2, so as to avoid dust and humid air entering the energy storage box 1 through the gap, thereby causing the equipment and electrical components in the energy storage box 1 to attach too much dust and humidity and other problems;

[0031] Then, when the air enters the energy storage box 1 through the fixed frame body 4, in this process, the filter screen 5 will preliminarily intercept the dust and other impurities in the air, so as to avoid a large amount of dust and other impurities entering the energy storage box 1 along with the air, and then the air will pass through the channel formed between the adjacent two electrostatic plates 6, in this process, the corona wire in the electrostatic plate 6 will ionize the air molecules through the tip discharge to generate positive and negative ions, so that the electrostatic plate 6 can adsorb the fine dust in the air, thereby ensuring that the dust wrapped in the air is further removed, so as to avoid some fine dust in the air falling on the equipment and electrical components in the energy storage box 1 after entering the energy storage box 1. Since the energy storage box 1 is in an unattended environment for a long time, it is not convenient to clean the dust in time, thereby affecting the heat dissipation of the equipment and electrical components. At the same time, since the electrostatic plate 6 is provided in a wave shape, the path of the air passing through the channel formed between the adjacent two electrostatic plates 6 is longer, so that the electrostatic plate 6 can more fully adsorb the fine dust in the air. In this way, the above-mentioned air dust treatment method of the filter screen 5 and the electrostatic plate 6 can solve the problem in the prior art that the mesh of the filter screen 5 is usually set to be relatively dense to enhance the interception of dust in the air. Although this method can achieve more effective dust interception effect, too dense mesh of the filter screen 5 will affect the passage of air, thereby reducing the heat dissipation effect inside the energy storage box 1. If the mesh of the filter screen 5 is set to be too large, a large amount of dust and other impurities will easily enter the energy storage box 1, so that the equipment and electrical components will attach a large amount of dust, thereby affecting the service life of the equipment and electrical components;

[0032] At the same time, when it is humid weather, the composite moisture-absorbing cotton 7 will absorb the water contained in the air after the air enters the channel formed between the adjacent two electrostatic plates 6, so as to avoid the air being too humid. Humid air entering the inside of the energy storage box 1 will easily affect the normal operation of the equipment and electrical components, and even cause short circuit of the equipment and electrical components in severe cases;

[0033] Then, when the filter screen 5 and the static plate 6 are used for a long time, the second multi-stage telescopic rod 32 is controlled to move the connecting rod 33 backward, the torsion spring rod 34 and the cleaning plate 35 move synchronously with the connecting rod 33, and the connecting pipe 37 is stretched. During the backward movement of the connecting rod 33, the cleaning plate 35 will contact the edge of the static plate 6. As the connecting rod 33 continues to move backward, because the elastic coefficient of the elastic member 8 is much smaller than that of the torsion spring rod 34, the cleaning plate 35 will push the static plate 6 to move backward, the elastic member 8 is compressed, and the elastic strip 9 moves backward synchronously with the static plate 6. Then the elastic strip 9 will clear the holes on the filter screen 5, so that the dust on the filter screen 5 will not block the holes and affect the air flow. At the same time, because the elastic strip 9 is arranged in a wave shape, the elasticity will contact the filter screen 5 and produce a slight vibration effect on the filter screen 5, so that the dust attached to the surface of the filter screen 5 will be shaken off. Then, after the elastic member 8 is compressed to the limit, the static plate 6 will not move backward, and as the cleaning plate 35 continues to move backward, the cleaning plate 35 will be deflected and the torsion spring rod 34 will be twisted. Then the cleaning plate 35 will enter the channel formed between the two adjacent static plates 6. During this process, the cleaning plate 35 will contact and press the composite moisture-absorbing cotton 7, so that the water in the composite moisture-absorbing cotton 7 will be squeezed out. It is explained that, when the heat dissipation fan 3 dissipates heat inside the energy storage box 1, the heat inside the energy storage box 1 will be discharged outward through the channel formed between the two adjacent static plates 6, so the heat can further dry the composite moisture-absorbing cotton 7. At the same time, the external pump is controlled to pass through the delivery pipe 36 and the connecting pipe 37 to generate negative pressure in the cleaning plate 35, so that the squeezed water will be sucked out by the cleaning plate 35. Then, the backward moving cleaning plate 35 will scrape off the dust adsorbed on the surface of the static plate 6, and the scraped dust will be sucked out by the cleaning plate 35. Thus, the cleaning of the static plate 6 is completed, so that the subsequent use of the static plate 6 will not be affected if the dust adsorbed on the static plate 6 is not treated in time.

[0034] It is explained that, when the remaining static plates 6 need to be cleaned, the first multi-stage telescopic rod 31 is controlled to move the second multi-stage telescopic rod 32 downward, the connecting rod 33, the torsion spring rod 34, the cleaning plate 35, the delivery pipe 36 and the connecting pipe 37 move synchronously with the second multi-stage telescopic rod 32, so that the connecting rod 33 is located in the middle of the channel formed between the two adjacent static plates 6. Then the second multi-stage telescopic rod 32 is controlled to move the connecting rod 33 backward, and the above-mentioned cleaning steps of the static plate 6 are repeated.

[0035] Those skilled in the art should understand that the above-mentioned embodiments do not limit the utility in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility.
