Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0020] Example 1: A highly protective aluminum power battery casing, such as Figures 1-10 As shown, it includes a housing 1, a cover 2, and a partition 3; the housing 1 is made of aluminum; the housing 1 has a cooling groove 11; the cover 2 is detachably connected to the housing 1; the housing 1 is fixedly connected to several partitions 3 for separating the battery cells 4; the housing 1 is fixedly connected to several temperature sensors, and the temperature sensors are located between every two partitions 3. It also includes hollow plates 101, elastic bladder I 102, elastic bladder II 103, water pipes 104, micro pumps 105, round rods 106, rectangular plates 107, connecting plates 108, and support rods 1018; the shell 1 is fixedly connected to several hollow plates 101, and the hollow plates 101 are fixedly connected to the partitions 3; each hollow plate 101 has several water outlet holes 1001; each hollow plate 101 is fixedly connected to an elastic bladder I 102, and the elastic bladder I 102 is detachably connected to the corresponding battery cell 4; each elastic bladder I 102 has several water inlet holes 21, and the water inlet holes 21 communicate with the water outlet holes 1001; each hollow plate 101 is fixedly connected to an elastic bladder II 103; each elastic bladder II 104... Each of the three partitions has several circular holes 31, which are connected to the water outlet 1001. A water pipe 104 is fixedly connected to the housing 1, and the water pipe 104 is located inside the housing 1. Several micro pumps 105 are connected to the water pipe 104, and the micro pumps 105 are connected to the corresponding hollow plates 101. Several circular rods 106 are slidably connected to each partition 3. A rectangular plate 107 is fixedly connected to every two circular rods 106 located in different partitions 3, and the rectangular plate 107 is connected to the corresponding battery cell 4 by a snap fastener. Several support rods 1018 are slidably connected to each partition 3. A connecting plate 108 is fixedly connected to every two support rods 1018 located in different partitions 3, and the connecting plate 108 is fixedly connected to the elastic bladder II 103.

[0021] It also includes support components; each connecting plate 108 is connected to a support component; each rectangular plate 107 is connected to another support component; the support component consists of a spring rod 109, a connecting block 1010 and a universal ball 1011; each connecting plate 108 is fixedly connected to a spring rod 109; each spring rod 109 is connected to a connecting block 1010; each connecting block 1010 is rotatably connected to a universal ball 1011.

[0022] It also includes connecting rods 1012, push plates 1013 and spheres 1019; each connecting plate 108 is fixedly connected to two connecting rods 1012, and the connecting rods 1012 are located in the cooling tank 11; the push plate 1013 is slidably connected in the cooling tank 11, and the push plate 1013 is slidably connected to all the connecting rods 1012; each connecting rod 1012 is fixedly connected to a sphere 1019, and the sphere 1019 is located on the side of the push plate 1013 away from the connecting plate 108.

[0023] It also includes effervescent tablets 1014, hydrophilic microporous membranes 1015, and folded bags 1016; the shell 1 has several guide grooves 12, and the guide grooves 12 are connected to the corresponding elastic bladders I 102; several effervescent tablets 1014 are placed in each elastic bladder I 102; a hydrophilic microporous membrane 1015 is fixedly connected to each water outlet 1001; several folded bags 1016 are fixedly connected to the shell 1 and all the partitions 3, and the folded bags 1016 are fixedly connected to the corresponding rectangular plates 107.

[0024] It also includes a drying ring 1017; each housing 1 is fixedly connected with a plurality of drying rings 1017, and the drying rings 1017 are located in the corresponding guide grooves 12.

[0025] The omnidirectional ball 1011 is made of engineering plastic and its surface is covered with an elastic rubber layer. By covering the surface of the omnidirectional ball 1011 with a rubber layer, the squeezing force on the photovoltaic panel when the omnidirectional ball 1011 rolls on the photovoltaic panel surface is reduced, thereby providing buffer protection for the photovoltaic panel.

[0026] To face Figure 1 Using the direction as a reference, in use, first install the battery cell 4 between the partitions 3 and cover it with the shell cover 2, then install the invention on the bottom of the photovoltaic cleaning robot, connect the pump on the cleaning robot to the cooling tank 11, connect the water pump used by the cleaning robot to clean the photovoltaic panel to the water pipe 104, and then place the photovoltaic cleaning robot on the photovoltaic panel. The invention provides power to the photovoltaic cleaning robot when cleaning the photovoltaic panel. The pump on the cleaning robot delivers cold water to the cooling tank 11, thereby circulating and cooling the shell 1 and the battery cell 4. The water pump delivers water to the nozzle of the photovoltaic cleaning robot, and then the nozzle cleans the photovoltaic panel. Due to the characteristics of the photovoltaic robot being unattended and operating at height, it is suitable for use in photovoltaic applications. When one of the battery cells 4 in the bottom of the cleaning robot malfunctions due to overheating, personnel often cannot detect and handle it in time. At this point, when the temperature sensor detects an abnormal and continuous rise in the temperature of the corresponding battery cell 4, the temperature sensor controls the corresponding micro pump 105 to start. The micro pump 105 transports water from the water pipe 104 to the hollow plate 101. Then, some of the water in the hollow plate 101 enters the elastic bladder I 102 through the water outlet 1001 and the water inlet 21. This causes the elastic bladder I 102 to expand after being filled with water, pushing the battery cell 4 and the rectangular plate 107 out of the housing 1. The rectangular plate 107 then drives the round rod 106 to slide out of the partition 3, allowing the round rod 106 to support and limit the rectangular plate 107 and the battery cell 4. Figure 8As shown, to prevent the battery cell 4 from directly detaching from the housing 1 and falling onto the photovoltaic panel, the overheated battery cell 4 is separated from other normal battery cells 4, ensuring that other battery cells 4 are not affected. The photovoltaic cleaning robot can continue to work temporarily, waiting for subsequent personnel to arrive and handle the situation. A portion of the hollow plate 101 enters the elastic bladder II 103 through the water outlet 1001 and the round hole 31. After the elastic bladder II 103 is filled with water and expands, it pushes the connecting plate 108 out of the housing 1. The connecting plate 108 drives the support rod 1018 to slide out of the partition 3, so that the support rod 1018 supports and limits the water-filled elastic bladder II 103 of the rectangular plate 107, preventing the water-filled elastic bladder II 103 from falling onto the photovoltaic panel. In addition, the water-filled elastic bladder II 103 balances the pushed-out battery cell 4, stabilizing the center of gravity of the photovoltaic cleaning robot and preventing the photovoltaic cleaning robot from tipping over due to the shift in the center of gravity, thereby damaging the photovoltaic panel.

[0027] Considering that the support of the support rod 1018 to the water-filled elastic bladder II 103 decreases after being pulled out of the partition 3, and that the support of the round rod 106 to the battery cell 4 decreases after being pulled out of the partition 3, to solve this problem, support components are set on the connecting plate 108 and the rectangular plate 107. Normally, when the photovoltaic cleaning robot walks on the photovoltaic panel surface, the omnidirectional ball 1011 contacts the photovoltaic panel surface and rolls, and the spring rod 109 buffers and dampens the protrusions at the photovoltaic panel connection, greatly reducing the swaying amplitude of the shell 1 and the photovoltaic robot, thus playing a buffering role. However, when the rectangular plate 107 and the battery cell 4 are pushed... When exiting the housing 1, the rectangular plate 107 drives the corresponding spring rod 109, connecting block 1010 and universal ball 1011 to move, so that the universal ball 1011 always rolls in contact with the surface of the photovoltaic panel, providing additional support for the ejected battery cell 4. At the same time, when the water-filled elastic bladder II 103 and the connecting plate 108 are ejected from the housing 1, the connecting plate 108 drives the corresponding spring rod 109, connecting block 1010 and universal ball 1011 to move, so that the universal ball 1011 always rolls in contact with the surface of the photovoltaic panel, providing additional support for the ejected water-filled elastic bladder II 103, and increasing the overall stability of the photovoltaic robot.

[0028] The micro pump 105 delivers water from the water pipe 104 into the hollow plate 101. When water is injected into the elastic bladder II 103, the connecting plate 108 is pushed out of the water-filled elastic bladder II 103. The connecting plate 108 drives the ball 1019 to move through the corresponding connecting rod 1012. The ball 1019 pulls the push plate 1013 to move closer to the micro pump 105, so that the push plate 1013 pushes the cooling water in the cooling tank 11 closer to the micro pump 105. At the same time, the micro pump 105 is controlled to open the valve 51, so that the push plate 1013 pushes part of the cooling water in the cooling tank 11 into the hollow plate 101 through the open valve 51, increasing the speed at which water enters the elastic bladder II 103, thereby increasing the ejection speed of the battery cell 4 and the water injection speed of the elastic bladder II 103.

[0029] Since there is a risk of fire after the battery cell 4 fails, after the micro pump 105 delivers water into the hollow plate 101, the water in the hollow plate 101 passes through the water outlet 1001 and then through the hydrophilic microporous membrane 1015 on the water inlet 21, and enters the elastic bladder I 102, where it comes into contact with the effervescent tablet 1014. The effervescent tablet 1014 reacts with water and quickly produces a large amount of carbon dioxide gas. This causes some of the gas to rapidly expand the elastic bladder I 102, pushing out the battery cell 4 and the rectangular plate 107. The rectangular plate 107 pulls out and unfolds the folded bag 1016, allowing the faulty battery cell 4 to enter the folded bag 1016 for isolation and protection. Some of the gas enters the folded bag 1016 through the guide groove 12, eventually filling the folded bag 1016 with carbon dioxide gas, forming a protective gas to isolate the air.

[0030] Considering that the carbon dioxide gas entering the guide channel 12 from the elastic bladder I 102 may contain water vapor, and that the water vapor may cause further malfunctions after entering the folded bag 1016 and coming into contact with the battery cell 4, in order to solve this problem, a drying ring 1017 is set in the guide channel 12 to absorb and dry the water vapor in the carbon dioxide gas entering the folded bag 1016.

[0031] Example 2, based on Example 1, such as Figures 5-10 As shown, it also includes a slide rod 201, a circular plate 202, and a conical plate 203; a number of slide rods 201 are fixedly connected to the hollow plate 101; each pair of slide rods 201 is slidably connected to a circular plate 202, and the position and number of circular plates 202 correspond to the water outlet 1001; each circular plate 202 is fixedly connected to two conical plates 203, and the center of the conical plate 203 is aligned with the center of the water outlet 1001.

[0032] It also includes a rotating rod 204, rope I 205, rope II 206 and spring body 207; the housing 1 is rotatably connected to several rotating rods 204; each rotating rod 204 is wound with a rope I 205; each rotating rod 204 is wound with a rope II 206, and the winding direction of rope II 206 is opposite to that of the corresponding rope I 205; each support rod 1018 is connected to a spring body 207.

[0033] A reflective pad is provided on the lower side of the housing 1.

[0034] The partition 3 is made of heat-insulating material to isolate the heat generated by each battery cell 4, so as to prevent the heat generated by the overheated battery cell 4 from being quickly transferred to other normal battery cells 4 when one of the battery cells 4 overheats.

[0035] Considering that when the photovoltaic cleaning robot moves on an inclined photovoltaic panel, if cell 4 is ejected by elastic bladder I 102 after a malfunction, and elastic bladder II 103 filled with water is ejected from the opposite side, due to the influence of gravity, cell 4 or water will tilt in the direction of the photovoltaic panel's tilt. This results in a significant difference between the ejection speed of cell 4 and the water injection speed of elastic bladder II 103, making the shell 1 prone to center of gravity shift and causing the cleaning robot to tip over. To solve this problem, we will describe it using an example where the photovoltaic panel is tilted to the left. When cell 4 is rapidly ejected by elastic bladder I 102 while tilting to the left, the circular plate 202 and the conical plate 203, under their own gravity, will discharge water towards the left side. The sliding of hole 1001 reduces the space of the left water outlet hole 1001. At the same time, as the circular plate 202 and the conical plate 203 move away from the right water outlet hole 1001, the space of the right water outlet hole 1001 increases. This reduces the speed at which water in the hollow plate 101 enters the elastic bladder I 102 from the left water outlet hole 1001, while increasing the speed at which water in the hollow plate 101 enters the elastic bladder II 103 from the right water outlet hole 1001. This counteracts the effect of gravity, reduces the speed difference between the ejection speed of the battery cell 4 and the water injection speed of the elastic bladder II 103, and prevents the shell 1 from easily shifting its center of gravity, which could cause the cleaning robot to tip over.

[0036] Considering that the rate at which the gas causes the elastic bladder I 102 to expand is slightly greater than the rate at which water enters the elastic bladder II 103, initially, the springs on the round rod 106 and the support rod 1018 are in a compressed state. When the battery cell 4 is rapidly ejected to the left by the expanded elastic bladder I 102, the battery cell 4 pushes the rectangular plate 107 and the round rod 106 to slide to the left out of the partition 3. The rectangular plate 107 pulls the rope I 205, causing the rotating rod 204 to rotate. After the rotating rod 204 rotates, it releases the restriction on the rope II 206, and thus the rope II 206 is released. 6. Release the restriction on the spring body 207, so that the support rod 1018 can quickly push the connecting plate 108 and its connected components to slide to the right under the elastic force of the spring body 207. The connecting plate 108 pulls the elastic bladder II 103 to unfold, so that a negative pressure is generated in the elastic bladder II 103. Then, under the action of pressure difference, the elastic bladder II 103 draws water from the hollow plate 101 through the round hole 31, which accelerates the speed at which water enters the elastic bladder II 103 and further reduces the speed difference between the ejection speed of the battery cell 4 and the water injection speed of the elastic bladder II 103.

[0037] Considering that the photovoltaic cleaning robot needs to walk on the surface of the photovoltaic panel, the heat absorbed by the photovoltaic panel will be continuously reflected to the lower side of the casing 1, causing the temperature of the lower side of the casing 1 to become too high due to heat accumulation. Therefore, by setting a reflective pad on the lower side of the casing 1, the heat on the surface of the photovoltaic panel is reflected outward, reducing the heat transferred from the photovoltaic panel to the lower side of the casing 1 and improving the heat insulation and cooling effect.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
