[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figures 1 to 14 The photovoltaic storage integrated box-type substation includes a box-type substation body 1, a fixed roof 2 is fixedly connected to the top of the box-type substation body 1, both ends of the box-type substation body 1 are slidably connected to a mobile box 3, the top of the mobile box 3 is slidably connected to a movable roof 7, the movable roof 7 is slidably connected to the fixed roof 2, a motor 8 is fixedly connected to the inside of the fixed roof 2, a group of symmetrically arranged driving gears 9 are fixedly connected to the output end of the motor 8, a driving sprocket 14 is fixedly connected to the middle position of the two driving gears 9, the front side of the box-type substation body 1 is rotatably connected to the front side plate 11, and the box-type substation body The rear side of the body 1 is rotatably connected to the rear side plate 13, the middle position of the upper end of the front side plate 11 is fixedly connected to a driven gear 10 meshing with the driving gear 9, the middle position of the upper end of the rear side plate 13 is fixedly connected to a driven sprocket 12, the driving sprocket 14 and the driven sprocket 12 are externally sleeved with a chain 15 meshing therewith, the middle position of the fixed roof 2 is connected to a pushing component, the pushing component is fixedly connected to the movable roof 7, the bottom of the fixed roof 2 is fixedly connected to a protective layer 23, the motor 8 and the pushing component are both located inside the protective layer 23, and the tops of the fixed roof 2 and the movable roof 7 are both fixedly connected to photovoltaic components.

[0021] The photovoltaic storage integrated box-type substation in the present invention needs to be inspected or maintained on rainy days. The maintenance personnel can start the motor 8, which will drive the driving gear 9 and the driving sprocket 14 to rotate. The driving gear 9 will push the driven gear 10 meshing therewith to rotate, thereby allowing the front side plate 11 to unfold, and the driving sprocket 14 will drive the driven sprocket 12 to rotate through the chain 15, thereby allowing the rear side plate 13 to unfold. In this way, a temporary canopy can be formed to reduce the impact of rain on maintenance personnel. Compared with the traditional method of first setting up the canopy and then conducting maintenance, this maintenance method is faster and more convenient. In addition, the structure of the box-type substation body 1 in the present invention is similar to a photovoltaic box-type substation structure that is convenient for busbar heat dissipation disclosed in the patent authorization announcement number CN117134214B, so it will not be elaborated on here.

[0022] As a preferred technical solution of the present invention, the pushing assembly includes a positioning frame 16, a transmission sprocket 17, a speed change gear 18, a follower gear 19, a fixed frame 20, a screw rod 21 and a threaded block 22. The positioning frame 16 is fixedly connected to the fixed roof 2. The middle position of the positioning frame 16 is rotatably connected to the transmission sprocket 17, and the transmission sprocket 17 is meshed with the chain 15. Both sides of the transmission sprocket 17 are fixedly connected to the speed change gear 18. One side of the speed change gear 18 is provided with a follower gear 19 meshed therewith. Both ends of the follower gear 19 are fixedly connected to the screw rod 21. One end of the screw rod 21 close to the follower gear 19 is rotatably connected to the fixing frame 20. The fixing frame 20 is fixedly connected to the fixed roof 2. The screw rod 21 is threadedly connected to the threaded block 22, and the threaded block 22 is fixedly connected to the bottom of the movable roof 7.

[0023] Specifically, when the motor 8 drives the active sprocket 14 to rotate, the active sprocket 14 will pull the chain 15 to move, and the transmission sprocket 17 meshing with the chain 15 will rotate accordingly, and the transmission sprocket 17 will drive the speed change gear 18 to rotate, and the speed change gear 18 will push the follower gear 19 meshing with it to rotate (because the diameter of the speed change gear 18 is much larger than the diameter of the follower gear 19, the follower gear 19 will rotate multiple times when the speed change gear 18 rotates one circle), and the follower gear 19 will drive the screw rod 21 to rotate, and because the threaded block 22 to which the screw rod 21 is threadedly connected is restricted by the movable roof 7 and cannot rotate and can only move in a straight line, the threaded block 22 will push the movable roof 7 to move away from the fixed roof 2, thereby expanding the rain shelter area of ​​the movable roof 7 at the end of the movable box 3, making it convenient for maintenance personnel to stand at the end of the movable box 3 to perform maintenance work.

[0024] As a preferred technical solution of the present invention, a slider 4 is fixedly connected to the bottom of the mobile box 3, a slide groove 6 is opened at the bottom of the box-type substation body 1, the slide groove 6 matches the slider 4, and a fixing bolt 5 is slidably connected to the middle position of the slider 4, and the fixing bolt 5 is threadedly connected to the box-type substation body 1.

[0025] Specifically, during transportation, the mobile box 3 can be pushed toward the direction close to the box-type substation body 1, so that a part of the entire substation is folded, so as to facilitate the transportation of the entire device. During installation, the mobile box 3 can be pushed away from the box-type substation body 1, so that the entire device is unfolded, allowing more space inside, thereby facilitating maintenance personnel to inspect and maintain the equipment inside. At the same time, the slider 4 and the fixing bolt 5 can limit the mobile box 3 to prevent the mobile box 3 from detaching from the box-type substation body 1.

[0026] As a preferred technical solution of the present invention, a fixed baffle 30 is fixedly connected to the inside of the mobile box body 3 close to the box-type substation body 1, and a movable baffle 29 slidably connected to the mobile box body 3 is provided on the side of the fixed baffle 30 away from the box-type substation body 1. Both the fixed baffle 30 and the movable baffle 29 are provided with equidistantly distributed air grooves, and both ends of the movable baffle 29 are connected to reset components.

[0027] As a preferred technical solution of the present invention, the reset component includes a wedge block 28, a limit block 31 and a reset elastic member 34. Limit grooves 32 are provided on both sides of the movable box 3. The limit grooves 32 are internally slidably connected to the limit blocks 31. The limit blocks 31 are fixed to the movable baffle 29. The bottom of the limit block 31 is fixedly connected to the reset elastic member 34. The lower end of the reset elastic member 34 is fixedly connected to the bottom of the limit groove 32. A guide groove 35 is provided in the middle position of the top of the movable baffle 29. A positioning groove 36 is provided in the middle position of the top of the fixed baffle 30. The bottom of the movable roof 7 is fixedly connected to a wedge block 28 matching the guide groove 35.

[0028] Specifically, if a fire occurs in the electrical equipment inside the box-type substation body 1 or inside the mobile box 3, the fire detection module inside the box-type substation body 1 will sound an alarm. At this time, the operator can start the motor 8 and let the motor 8 rotate in the reverse direction. After the transmission is transmitted through the active sprocket 14, the chain 15, the transmission sprocket 17, the speed gear 18 and the follower gear 19, the screw rod 21 will also rotate in the reverse direction under the drive of the follower gear 19, so that the movable roof 7 moves toward the direction of the fixed roof 2, so that the movable roof 7 will drive the wedge block 28 to insert into the guide groove 35, and the wedge block 28 will squeeze the movable The baffle plate 29 moves downward and is offset from the fixed baffle plate 30, thereby isolating the fire and preventing the fire from spreading easily. After the fire is extinguished, the motor 8 can rotate forward again to reset the movable roof 7. After the movable baffle plate 29 loses the restriction of the wedge block 28, the reset elastic member 34 will push the limit block 31 upward, and drive the movable baffle plate 29 back to its original position through the limit block 31, thereby facilitating daily air circulation and heat dissipation inside the substation. In addition, if an automation control module is installed inside the main body 1 of the box-type substation, the motor 8 can also be connected to the automation control module so that the motor 8 can work automatically.

[0029] As a preferred technical solution of the present invention, a positioning rod 33 is fixedly connected to the middle position of the limiting groove 32 , a reset elastic member 34 is sleeved on the outside of the positioning rod 33 , and the limiting block 31 is slidably connected to the positioning rod 33 .

[0030] Specifically, by limiting the limit block 31 and the reset elastic member 34 through the positioning rod 33 , displacement of the limit block 31 and the reset elastic member 34 can be avoided, which would cause damage to the limit block 31 and the reset elastic member 34 .

[0031] As a preferred technical solution of the present invention, a storage groove 25 is provided on the front and rear sides of the box-type substation body 1, a support rod 26 is provided inside the storage groove 25, the upper end of the support rod 26 is rotatably connected to the storage groove 25, and a card slot 24 matching the support rod 26 is provided on both sides of the front side plate 11 and the rear side plate 13.

[0032] As a preferred technical solution of the present invention, a magnetic block 27 is fixedly connected to the lower end of the support rod 26 , and the magnetic block 27 and the box-type substation body 1 are attracted to each other.

[0033] Specifically, after the front side panel 11 and the rear side panel 13 are unfolded, the support rod 26 can be rotated until the lower end of the support rod 26 is in the slot 24. At this time, under the action of the magnetic block 27, the lower end of the support rod 26 will always be in the slot 24. If the front side panel 11 and the rear side panel 13 lose their restrictions, the support rod 26 will provide support for the front side panel 11 and the rear side panel 13 to prevent the front side panel 11 and the rear side panel 13 from injuring the staff located below. During the daily operation of the box-type substation body 1, the support rod 26 is in the storage slot 25, and the lower end of the support rod 26 can be adsorbed and fixed in the storage slot 25 by the magnetic block 27 to prevent the support rod 26 from shaking and hitting the front side panel 11 or the rear side panel 13 to generate noise.

[0034] It is worth noting that the motor 8 involved in the present invention is an existing mature product, so it is not elaborated in detail here, and the motor 8 is powered by an additional circuit (such as a photovoltaic module, etc.), and is not easily affected by power outages during a fire. At the same time, the control of the motor 8 can be connected to the control system of the box-type substation body 1 itself for control, or an additional remote control module can be installed to control the start of the motor 8 through a remote terminal. Since these are all existing mature technologies, they will not be elaborated on here.

[0035] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
