[0002] The photovoltaic effect of the battery directly converts solar radiation energy into electrical energy, which needs to be collected and stored. Generally, photovoltaic equipment is installed in outdoor environments for use. During the long-term charging process of photovoltaic batteries, heat will be generated and heat needs to be dissipated to avoid adverse effects caused by overheating due to charging.

DETAILED DESCRIPTION

[0038] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0039] Example 1

[0040] A photovoltaic energy storage charging device, according to Figure 1-6 As shown, it includes a bottom plate 1, a cabinet 2, a fan 3, a driving assembly, a box 4, a filter 5 and a partition 8; the cabinet 2 is installed on the upper part of the bottom plate 1; two fans 3 are installed on the left part of the cabinet 2; a plurality of driving assemblies are connected to the bottom of the inner side of the cabinet 2, each driving assembly is connected to a box 4, and a temperature sensor is arranged in the box 4; the driving assembly is used to drive the box 4 to move; each box 4 is fixedly connected to a filter 5; each box 4 is fixedly connected to two partitions 8 inside;

[0041] It also includes a baffle 201, a cover plate 202, a support frame 203, a round rod 204, a rolling curtain 205 and an elastic member I 206; four baffles 201 are slidably connected to the front of the cabinet 2; a cover plate 202 is fixedly connected to the upper surface of each baffle 201, and the cover plate 202 is slidably connected to the cabinet 2; a support frame 203 is fixedly connected to the front left and front right of the cabinet 2; a round rod 204 is rotatably connected to each support frame 203; a rolling curtain 205 is sleeved on the outside of each round rod 204, and a shielding portion 2051 is provided on the rolling curtain 205, and the shielding portion 2051 is fixedly connected to the corresponding baffle 201; two elastic members I 206 are sleeved on the outside of the round rod 204, and one end of the elastic member I 206 is fixedly connected to the support frame 203, and the other end of the elastic member I 206 is fixedly connected to the round rod 204.

[0042] Two scrapers 2011 are provided at the lower part of each baffle 201 for cleaning the guide rail 7 .

[0043] A plurality of inclined grooves 2052 are formed on the upper portion of the shielding portion 2051 for guiding water.

[0044] The driving assembly includes an electric slider 6 and a guide rail 7 ; two guide rails 7 are fixedly connected to the inner bottom of the cabinet 2 ; an electric slider 6 is slidably connected to each guide rail 7 , and the two electric sliders 6 are fixedly connected to the same box 4 .

[0045] When cooling the storage battery 9: During normal cooling, all the storage batteries 9 are arranged in a row, such as Figure 1As shown, when the temperature in the cabinet 2 is high due to the heating of the battery 9, the two fans 3 are controlled to operate to supply air into the cabinet 2, and the gas passes through all the boxes 4 from left to right in sequence, and is finally discharged from the right part of the cabinet 2, thereby achieving heat dissipation for all the batteries 9. At the same time, the gas is filtered through the corresponding filter 5, thereby intercepting impurities in the gas, preventing the impurities from drifting onto the battery 9 and affecting the normal use of the battery 9;

[0046] When the temperature sensor in the box body 4 detects that the temperature of the battery 9 is overheated, the corresponding group of electric sliders 6 are controlled to start moving along the guide rail 7. The group of electric sliders 6 move to drive the box body 4 to move to the end of the guide rail 7 away from the cabinet 2. The movement of the box body 4 drives the battery 9 to move, thereby making the overheated battery 9 independent. At this time, the outside air passes through the corresponding partition 8 and directly contacts the battery 9, so as to achieve cooling of the battery 9. After the battery 9 is at a normal temperature, the electric slider 6 is started to drive the box body 4 to move. The movement of the box body 4 drives the battery 9 to reset, thereby achieving cooling of the overheated battery 9. The method of isolating the overheated battery 9 is adopted to avoid the problem that the gas needs to pass through multiple batteries 9 from left to right in sequence during normal heat dissipation, which causes the gas to heat up and reduces the heat dissipation efficiency of the remaining batteries 9 on the right.

[0047] After the overheated storage battery 9 is separated, in a rainy environment, the separated storage battery 9 is very susceptible to rain. The following will discuss the storage battery 9 on the far left and a rolling curtain 205. The initial state of the shielding portion 2051 is rolled up. During the separation of the storage battery 9, the box body 4 moves and touches the baffle 201, and squeezes the baffle 201, thereby driving the baffle 201 to move. The movement of the baffle 201 drives the scraper 2011 and the cover plate 202 to move, so that the upper part of the box body 4 is shielded by the cover plate 202, that is, the upper part of the storage battery 9 is shielded. At the same time, the movement of the baffle 201 drives the shielding portion 2051 of the rolling curtain 205 to move, so that the shielding portion 2051 moves to the left side of the box body 4 and is located on the left side of the filter screen 5, so that the left side of the storage battery 9 is protected by the shielding portion 2051. The shielding part 2051 is used to block the rain to prevent the battery 9 from being splashed with rain in a rainy environment and affecting the use of the battery 9. At this time, the outside air dissipates the heat of the battery 9 through the shielding part 2051. When rain falls on the upper surface of the cover plate 202, the rain will fall along the upper surface of the cover plate 202. At this time, the rain is diverted by the inclined groove 2052 to make the rain fall on the surface of the shielding part 2051, thereby intercepting the rain by the shielding part 2051 to prevent the rain from falling on the battery 9. At the same time, the shielding part 2051 moves to drive the round rod 204 to rotate, and the round rod 204 rotates to twist the two elastic members Ⅰ206, so that the two elastic members Ⅰ206 accumulate force. When the box body 4 moves to reset, the round rod 204 is rotated and reset by the rebound force generated by the two elastic members Ⅰ206, thereby driving the roller blind 205 and the shielding part 2051 to be rolled up.

[0048] Embodiment 2:

[0049] Based on the first embodiment, Figure 5 and Figure 7-10 As shown, it also includes a protection unit; the protection unit includes a sliding block 301, an arc block I 3011, an arc block II 3012, a conduit I 302, a joint I 3021, a water absorbing member 303, a bottom plate 304, a guide plate 305 and a water collecting assembly; each support frame 203 is slidably connected to two sliding blocks 301, and a spring is connected between the sliding block 301 and each support frame 203; each sliding block 301 is fixedly connected to an arc block I 3011; each baffle 201 is fixedly connected to two arc blocks II 3012; two other arc blocks II 3012 are fixedly connected to the surface of each cover plate 202; all sliding blocks 301 on the same support frame 203 are commonly fixedly connected to a conduit I 302, and a connector I 3021 is fixedly connected to the lower end of the conduit I 302; a water absorbing member 303 is fixedly connected to the outer annular surface of the conduit I 302; a bottom plate 304 is fixedly connected to the lower part of the outer annular surface of the conduit I 302; a guide plate 305 is fixedly connected to the inner side of the bottom plate 304; a water collecting component is connected to each support frame 203; the water collecting component is used to collect water in the water absorbing member 303.

[0050] The upper part of the bottom plate 304 is configured to be funnel-shaped for collecting water.

[0051] The guide plate 305 is configured to be funnel-shaped to guide water.

[0052] The water collecting assembly includes an arc plate 306, a fixed plate 307, a joint II 3071 and a nozzle 3072; two arc plates 306 are fixedly connected to each support frame 203; all the arc plates 306 on the same support frame 203 are fixedly connected to the fixed plate 307; the lower part of the fixed plate 307 is fixedly connected and connected to the joint II 3071; the side of the arc plate 306 away from the joint II 3071 is fixedly connected and connected to multiple nozzles 3072.

[0053] A protrusion 3061 is provided in the middle of the arc plate 306 for squeezing the water absorbing member 303 .

[0054] When collecting rainwater: after the rainwater falls on the surface of the shielding part 2051, part of the rainwater will flow downward along the surface of the shielding part 2051, and part of the rainwater will pass through the shielding part 2051 and contact the filter 5. When the rolling curtain 205 and the shielding part 2051 are being rolled up, the water absorbing member 303 contacts the surface of the shielding part 2051 and absorbs the rainwater falling on the surface of the shielding part 2051, so that the rainwater is concentrated in the water absorbing member 303, and the rainwater that passes through the shielding part 2051 and contacts the filter 5 will contact the impurities intercepted on the filter 5, thereby wetting the impurities such as dust. When the filter 5 needs to be cleaned, the corresponding baffle 201 and the corresponding cover plate 202 are in the process of resetting and moving, and the movement of the baffle 201 drives the corresponding The arc block II 3012 moves, and the cover plate 202 moves to drive another arc block II 3012 to move. At this time, the two arc blocks II 3012 move to touch the corresponding arc block I 3011, and squeeze the arc block I 3011, so that the sliding block 301 moves along the support frame 203 and compresses the spring between the sliding block 301 and the support frame 203. The movement of the sliding block 301 drives the guide tube I 302 to move, and the movement of the guide tube I 302 drives the water absorbing member 303 to move close to the shielding portion 2051. At this time, the water absorbing member 303 is blocked by the shielding portion 2051, and the water in the water absorbing member 303 will be squeezed out, so that part of the rainwater concentrated in the water absorbing member 303 flows through the shielding portion 2051 to the filter screen 5, thereby cleaning the filter screen 5;

[0055] Moreover, after the water absorbing member 303 is blocked by the shielding portion 2051, the remaining rainwater in the water absorbing member 303 will flow into the conduit I 302 and flow out through the joint I 3021. At the same time, the remaining rainwater in the water absorbing member 303 will flow downward under the influence of gravity. At this time, the rainwater is guided by the bottom plate 304 and the guide plate 305, and the rainwater flows into the conduit I 302 and finally flows out from the joint I 3021. In order to facilitate the subsequent use of the water absorbing member 303, it is necessary to squeeze out the water in the water absorbing member 303 and pre-filter the external device. The pump for transmitting gas is connected to the connector II 3071, and the water absorbing member 303 moves between the two arc-shaped plates 306 in the same manner as described above. At this time, the water absorbing member 303 is squeezed by the two protrusions 3061, thereby squeezing out the water in the water absorbing member 303. At the same time, the external pump is controlled to start sucking air through the connector II 3071, so that negative pressure is generated in the fixed plate 307, and the residual water in the water absorbing member 303 is sucked through the multiple nozzles 3072, so as to remove the water in the water absorbing member 303 for the next use.

[0056] Embodiment three:

[0057] Based on the second embodiment, according to Figure 11-13 As shown, it also includes a crushing unit; the crushing unit includes a heat-conducting fin 41, a through hole 81, a conduit II 401, a bottom box 402, a square tube 403, a cylinder 404, an elastic member II 405 and a top block 406; the bottom of the inner side of the box body 4 is fixedly connected to the heat-conducting fin 41; each partition 8 is provided with a plurality of through holes 81; a conduit II 401 is fixedly connected to the rear of each cabinet 2, and the conduit II 401 is a telescopic structure; a bottom box 402 is fixedly connected to the front of each conduit II 401 ; Each bottom box 402 is fixedly connected to a box body 4, and the lower part of each heat-conducting fin 41 is located in the corresponding bottom box 402; two square tubes 403 are fixedly connected to each bottom box 402; each square tube 403 is fixedly connected and connected to a cylinder 404; the cylinder 404 is slidably connected to the baffle 201; two elastic members Ⅱ405 are fixedly connected to the inner side of each cylinder 404; the telescopic parts of all elastic members Ⅱ405 on the same cylinder 404 are commonly fixedly connected to a top block 406.

[0058] The top block 406 is configured to be in a cone shape, and is used to break ice cubes on the outer surface of the baffle 201 .

[0059] Before cooling the battery 9: pre-connect the pump machine of another peripheral device for gas transmission to the conduit II 401. Since the photovoltaic energy storage charging device is installed in an outdoor environment, and the outdoor environment has low temperature and high humidity, the outer surface of the cabinet 2 is very prone to ice formation in cold weather. When the battery 9 is overheated or in an accident and needs to be quickly cooled, the battery 9 heats up quickly, and it is difficult to quickly melt the large area of ​​ice on the outer surface of the cabinet 2 in a short time, which affects the movement of the battery 9 and the heat dissipation of the battery 9. The heat is conducted to the battery 9 through the heat conducting fins 41, so that the heat generated by the battery 9 is conducted to the heat conducting fins 41. In the sheet 41, the external pump is then controlled to start supplying gas to the conduit II 401. At this time, the gas flows along the bottom box 402, the square tube 403 and the cylinder 404, and finally passes through the gap between the cylinder 404 and the top block 406 and blows toward the outer surface of the cabinet 2. At the same time, when the gas passes through the bottom box 402, a negative pressure is generated in the bottom box 402, and then the heat absorbed by the heat-conducting fins 41 is absorbed, thereby absorbing part of the heat generated by the storage battery 9, and the temperature of the gas in the bottom box 402 is increased, and then the temperature of the gas in the square tube 403 and the cylinder 404 is increased, so that the hot air is blown toward the ice on the outer surface of the cabinet 2, and the ice on the outer surface of the cabinet 2 is melted, so as to facilitate the movement of the storage battery 9;

[0060] When the hot air passes through the gap between the cylinder 404 and the top block 406, the hot air is compressed, thereby accelerating the flow rate of the hot air, thereby further accelerating the melting speed of the ice on the outer surface of the cabinet 2. At the same time, part of the gas will directly blow to the top block 406 and push the top block 406 to move, so that the top block 406 is exposed from the cylinder 404, and at the same time, the two elastic members II 405 are stretched, so that the ice on the outer surface of the cabinet 2 is broken by the movement of the top block 406, thereby preventing the ice from blocking the movement of the battery 9, improving the heat dissipation efficiency of the battery 9, and absorbing part of the heat generated by the battery 9 through the bottom box 402, further improving the heat dissipation efficiency of the battery 9;

[0061] In order to prevent ice cubes on the guide rail 7 from affecting the movement of the baffle 201, when the baffle 201 moves, the movement of the baffle 201 drives the corresponding scraper 2011 to move, and the scraper 2011 moves along the surface of the guide rail 7, thereby scraping off the ice cubes on the surface of the guide rail 7 through the scraper 2011.

[0062] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
