[0035] It also includes a connecting pipe 1 2, an air supply pipe 3, an air outlet pipe 4, a connecting pipe 2 5 and an air extraction pipe 6; the energy storage rack 1 is fixedly connected to the connecting pipe 1 2, and the connecting pipe 1 2 is connected to an external air supply mechanism; the connecting pipe 1 2 is connected to two air supply pipes 3, and the air supply pipe 3 is fixedly connected to the energy storage rack 1; each air supply pipe 3 is connected to a plurality of air outlet pipes 4, and the air outlet pipe 4 is connected to the placement chamber 1a; the energy storage rack 1 is fixedly connected to the connecting pipe 2 5, and the connecting pipe 2 5 is connected to an external air extraction mechanism; the connecting pipe 2 5 is connected to the air extraction pipe 6, and the air extraction pipe 6 is fixedly connected to the energy storage rack 1, and the air extraction pipe 6 is connected to the placement chamber 1a.

[0036] It also includes a shielding unit and a connecting plate 102; the placement chamber 1a is connected to the shielding unit; the shielding unit is connected to the connecting plate 102, and the connecting plate 102 is fixedly connected to the scraping plate 13, and the scraping plate 13 is slidably connected on the frame of the wire mesh frame 12.

[0037] It also includes a receiving plate 101; each wire mesh frame 15 is fixedly connected with a plurality of receiving plates 101, and the receiving plates 101 are in contact with the energy storage battery 100.

[0038] The size of the steel mesh frame 12 and the steel mesh frame 2 15 is the same as the size of the corresponding side surface of the energy storage battery 100 , so that each expanded part of the energy storage battery 100 can be detected.

[0039] The plurality of receiving plates 101 are all straight and staggered, and can receive dry powder so that the dry powder covers the left and right sides of the energy storage battery 100 .

[0040] A plurality of inclined grooves 17a are respectively provided on the left and right sides of the bottom plate 17, and a collecting groove 17b is provided in the middle of the bottom plate 17, and the collecting groove 17b is connected to the inclined groove 17a, and the electrolyte leaked from the energy storage battery 100 due to expansion can be collected in the collecting groove 17b through the inclined groove 17a.

[0041] The working steps of the above embodiment are as follows: when the present invention is working, the energy storage rack 1 is opened manually, the corresponding dry powder is first added into the dry powder box 7, and the electric roller is controlled to rotate the two cover plates 8 to close the dry powder box 7;

[0042] Then, the energy storage battery 100 is manually placed in the placement chamber 1a, and the corresponding power connector is connected to the interface on the front side of the energy storage battery 100. At this time, the energy storage battery 100 is placed on the upper side of the bottom plate 17, and the steel wire mesh frame 12 is located above the energy storage battery 100, and the two steel wire mesh frames 2 15 are respectively located on the left and right of the energy storage battery 100. Figure 3 As shown; the placement of the energy storage battery 100 is completed in this way, and then the energy storage rack 1 is closed, and the electrical energy is subsequently converted into chemical energy for storage through the energy storage battery 100; and in the process of placing the energy storage battery 100, under the action of the elastic telescopic rod 14, the two steel wire mesh frames 15 move to clamp and fix the energy storage battery 100, so as to prevent the energy storage battery 100 from moving when the energy storage rack 1 is moved later. At the same time, a plurality of receiving plates 101 are arranged on the steel wire mesh frame 15, and the steel wire mesh frame 15 contacts and clamps the energy storage battery 100 through the receiving plates 101. Compared with the existing flat plate clamping, the contact area with the energy storage battery 100 can be reduced, thereby ensuring the normal heat dissipation of the energy storage battery 100;

[0043] In addition, during the use of the energy storage battery 100, the external air supply structure is controlled to blow air out from the air outlet pipe 4 through the connecting pipe 2 and the air supply pipe 3 in sequence, and the air is blown into the placement chamber 1a to cool the energy storage battery 100, and the external air extraction mechanism is controlled to extract air from the placement chamber 1a through the connecting pipe 2 5 and the air extraction pipe 6 in sequence, so as to extract the high-temperature gas inside the placement chamber 1a in time; the air outlet pipe 4 and the air extraction pipe 6 cooperate with each other to realize the circulation of the air inside the placement chamber 1a, so that the temperature inside the placement chamber 1a is kept at a normal temperature, so as to avoid the energy storage battery 100 from continuously generating heat when in use, causing the temperature inside the placement chamber 1a to rise, thereby affecting the normal use of the energy storage battery 100;

[0044] However, when the energy storage battery 100 is in use, if the charging voltage is excessive or the internal voltage changes too much, it is easy to cause the battery to swell and leak, and then catch fire and explode, causing economic damage; therefore, when the energy storage battery 100 is in use, when it swells, since the upper side, lower side, left side and right side of the energy storage battery 100 are thinner than the front side or the rear side, the energy storage battery 100 will swell first at the upper side, lower side, left side or right side of the energy storage battery 100. When the upper side or lower side of the energy storage battery 100 swells, the expansion of the energy storage battery 100 will squeeze the upper steel mesh frame 12, and drive the steel mesh frame 12 and other connected parts to move upward, the elastic telescopic rod 11 will contract, and the sensor 2 10 on the steel mesh frame 12 will move upward and contact the sensor 19 aligned with it. When the sensor 19 contacts the sensor 2 10, the control The electric roller on the dry powder box 7 drives the two cover plates 8 to rotate towards each other, opens the dry powder box 7, and makes the dry powder stored in the dry powder box 7 fall down to cover the entire energy storage battery 100. The expansion drives the steel wire mesh frame 12 to move, opens the dry powder box 7, and covers the energy storage battery 100 with dry powder, so as to avoid fire and explosion after the energy storage battery 100 expands, thereby reducing economic damage; correspondingly, when the left or right side of the energy storage battery 100 expands, the expansion of the energy storage battery 100 will drive the corresponding steel wire mesh frame 2 15 and sensor 3 16 to move, and the sensor 3 16 moves to contact the wall of the placement chamber 1a and sense it, thereby controlling the dry powder box 7 to open, and similarly making the dry powder in the dry powder box 7 scatter, covering the energy storage battery 100, and preventing fire and explosion; and when the sensor 1 9 or the sensor 3 16 senses, the shielding unit will be controlled to shield the air outlet pipe 4 and stop blowing;

[0045] However, when the dry powder in the dry powder box 7 falls downward to cover the energy storage battery 100, the dry powder falling downward first falls on the middle of the energy storage battery 100, and then gradually spreads to other parts of the energy storage battery 100, and the amount of dry powder stored in the dry powder box 7 is certain, so a large amount of dry powder will accumulate in the middle of the energy storage battery 100, making it difficult for other parts to be covered with dry powder, and it is still easy to cause fire and explosion, and the dry powder in the dry powder box 7 is easy to clump into blocks after long-term storage, affecting the subsequent dry powder coverage; in this regard, when the shielding unit is controlled to move, the shielding unit will also drive the connecting plate 102 to move, and the connecting plate 102 will drive the scraping plate 13 to slide on the frame of the wire mesh frame 12, and the shielding unit is controlled to move. The unit drives the scraper plate 13 to repeatedly move left and right. The scraper plate 13 repeatedly moves left and right on the steel wire mesh frame 12, and the dry powder dropped on the middle of the energy storage battery 100 is repeatedly pushed left and right, and the dry powder in the middle is pushed to both sides, so as to avoid the dry powder accumulating in the middle, which makes it difficult for other parts to be covered with dry powder, and it is still easy to catch fire and explode; at the same time, when the dry powder falls, the steel wire mesh frame 12 can screen the fallen dry powder, and the agglomerated dry powder can be screened out, and in the subsequent process of repeated movement and pushing of the scraper plate 13, the agglomerated dry powder screened out can also be scraped and squeezed, and the agglomerated dry powder can be squeezed and broken, so that it can still cover and protect the energy storage battery 100;

[0046] At the same time, the receiving plates 101 arranged on the left and right steel wire mesh frames 15 are all straight and staggered. When dry powder falls from the left and right sides of the energy storage battery 100, the receiving plates 101 can receive the falling dry powder, so that the dry powder will not fall directly on the bottom of the left and right sides of the energy storage battery 100, but can be evenly covered on the left and right sides of the energy storage battery 100, so as to avoid the dry powder from falling directly and accumulating on the bottom of the left and right sides of the energy storage battery 100, resulting in the middle and upper parts of the left and right sides of the energy storage battery 100 not being covered by the dry powder;

[0047] After the energy storage battery 100 swells, the electrolyte and other liquids inside it will leak out. When the leaked liquid flows and accumulates at the bottom, the bottom of the entire energy storage battery 100 will be immersed in the leaked liquid. The leaked liquid has a certain toxicity, which is not conducive to subsequent manual processing. A plurality of inclined grooves 17a are opened on the left and right sides of the bottom plate 17, and a collecting groove 17b is opened in the middle of the bottom plate 17. The collecting groove 17b is connected to the inclined groove 17a. When leakage occurs, the leaked liquid can be collected in the collecting groove 17b, which can greatly reduce the subsequent manual processing procedures.

[0048] Example 2

[0049] On the basis of Example 1, Figure 9-11As shown, the shielding unit includes an electric push rod 201 and a shielding plate 202; four electric push rods 201 are fixedly connected to the upper side of the placement chamber 1a; each two adjacent electric push rods 201 are each commonly fixedly connected to a shielding plate 202, and the shielding plate 202 on the right is fixedly connected to the connecting plate 102.

[0050] The shielding plate 202 is provided with a plurality of through holes 202a, and the through holes 202a are configured as tapered holes that are larger at the top and smaller at the bottom, so that the air outlet pipe 4 can be intermittently blown through the through holes 202a.

[0051] It also includes an electric telescopic rod 203 and a shielding block 204; the placement chamber 1a is fixedly connected to a plurality of electric telescopic rods 203; all the electric telescopic rods 203 are commonly fixedly connected to a shielding block 204, and the shielding block 204 is used to shield the exhaust pipe 6.

[0052] When the dry powder box 7 is opened and the dry powder stored inside falls out, the air outlet pipe 4 and the air extraction pipe 6 continue to blow or extract air, which will cause the dry powder to be blown and unable to cover the energy storage battery 100, or the dry powder will be extracted, affecting the fire extinguishing effect of the dry powder; therefore, at the beginning, the shielding plate 202 is located on one side of the air outlet pipe 4, and the air outlet pipe 4 is connected to the placement chamber 1a. When the sensor 1 9 or the sensor 3 16 is sensed, the electric push rod 201 is controlled to drive the shielding plate 202 to move and shield the air outlet pipe 4, so that when the dry powder box 7 is opened and the dry powder falls out, the air outlet pipe 4 is in a shielded state to prevent the air outlet pipe 4 from blowing, so that the dry powder cannot cover the surface of the energy storage battery 100;

[0053] At the same time, the shielding plate 202 is provided with a plurality of through holes 202a, and the through holes 202a are set as tapered holes that are larger at the top and smaller at the bottom. In the process that the shielding plate 202 moves to shield the air outlet pipe 4, taking the shielding plate 202 on the right side as an example, the shielding plate 202 will move under the drive of the electric push rod 201, and the electric push rod 201 is controlled to drive the shielding plate 202 to move left and right repeatedly, so that the through holes 202a are intermittently connected with the air outlet pipe 4, so that the air outlet pipe 4 can continue to blow out intermittently, and the air outlet pipe 4 can intermittently blow out through the through holes 202a. When the dry powder box 7 is just opened and the dry powder falls out, the dry powder that has just fallen out can be blown so that the dry powder can quickly fill the entire placement chamber 1a and cover the energy storage battery 100. The through holes 202a are set as tapered holes. When the air is blown out intermittently, Fig.10 As shown, it is possible to blow air outward in different directions to blow the dry powder to various parts so that the dry powder can fully cover the entire placement chamber 1a; and when the dry powder is covered, the electric push rod 201 is controlled to reset, the shielding plate 202 stops moving and shields the air outlet pipe 4, at this time, the through hole 202a stops intermittently communicating with the air outlet pipe 4, the air outlet pipe 4 stops blowing air outward, and the dry powder can still smoothly cover the energy storage battery 100;

[0054] Moreover, initially, the shielding block 204 is located on the right side of the exhaust pipe 6, and the exhaust pipe 6 is connected to the placement chamber 1a. When the sensor 1 9 or the sensor 3 16 senses, the electric telescopic rod 203 is controlled to drive the shielding block 204 to move, and the shielding block 204 moves to shield the exhaust pipe 6, so as to prevent the exhaust pipe 6 from extracting the dry powder when the dry powder falls;

[0055] And after the protection of the energy storage battery 100 is finally completed, when the energy storage rack 1 is manually opened to check the state of the expanded energy storage battery 100, harmful gas will be generated when the energy storage battery 100 expands and leaks; therefore, the manual operation can first control the electric telescopic rod 203 to drive the blocking block 204 to move, so that the exhaust pipe 6 continues to be connected to the placement chamber 1a, and the harmful gas generated by the expansion is extracted through the exhaust pipe 6, so as to avoid the harmful gas generated being inhaled into the body when the manual operation is opened for inspection.

[0056] The above description is only an example of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention should be included in the protection scope of the present invention. The contents not elaborated in detail in the present invention belong to the existing technologies known to those skilled in the art.
