[0017] 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.

[0018] See also Figure 1-Figure 12 A prefabricated energy-saving substation box body comprises a shell 1, a base 2 connected to the bottom of the shell 1, and a double-opening box door 3 connected to both ends and the outside of the shell 1. Both ends of the shell 1 are connected with a rain shielding mechanism, and the rain shielding mechanism comprises a first U-shaped rain shielding plate 5 and a second U-shaped rain shielding plate 6. The first U-shaped rain shielding plate 5 is slidably connected to the inner wall of the shell 1, and the second U-shaped rain shielding plate 6 is slidably connected to the inner wall of the first U-shaped rain shielding plate 5. The front inner wall of the first U-shaped rain shielding plate 5 is fixedly connected with a sealing plate 7, and the sealing plate 7 and the second U-shaped rain shielding plate 6 are fixedly connected. The outer wall is slidably connected, and the top surface of the base 2 is fixedly connected with two symmetrically arranged multi-stage electric push rods 8, and the output ends of the two multi-stage electric push rods 8 are respectively fixedly connected to the outer walls of the two vertical plates of the second U-shaped rain shield 6. A rain sensor 4 is fixedly installed on the top of the outer shell 1, and a touch switch 13 electrically connected to the rain sensor 4 is embedded on the door frame of the outer shell 1. A second switch 12 corresponding to the touch switch 13 is fixedly installed on the top inner wall of one of the door panels of the double-leaf door 3, and a first switch 11 is fixedly installed on the top surface of the base 2.

[0019] The prefabricated energy-saving substation box in the present invention will detect rain when it rains, and the touch switch 13 can be energized through the rain sensor 4. When the maintenance personnel carry out emergency repairs on the distribution cabinet in the substation on rainy days, they open the double-door box 3 to separate the second switch 12 from the touch switch 13, energize the multi-stage electric push rod 8, and activate the output end of the multi-stage electric push rod 8 to push the second U-shaped rain shield 6 to slide on the inner wall of the first U-shaped rain shield 5. When the second U-shaped rain shield 6 moves to a certain distance, it will drive the first U-shaped rain shield 5 to slide, so that the first U-shaped rain shield 5 slides out of the outer shell 1 for a distance. At this time, the first U-shaped rain shield 5 and the second U-shaped rain shield 6 are unfolded at the same time, and a larger U-shaped protection area is propped up at both ends of the outer shell 1. In this way, workers standing in the U-shaped protection area can smoothly inspect and repair without getting wet in the rain.

[0020] The provision of the rain sensor 4 can prevent the rain shielding mechanism from extending when the double-door 3 is opened during routine maintenance.

[0021] When the second U-shaped rain shield 6 is sliding, the outer wall of the second U-shaped rain shield 6 will slide under the lower end of the sealing plate 7 inside the outer end of the first U-shaped rain shield 5. The sealing plate 7 is also U-shaped, and the contact surface of the sealing plate 7 and the second U-shaped rain shield 6 are against each other. This arrangement ensures that the second U-shaped rain shield 6 can slide and prevents rainwater from falling between the first U-shaped rain shield 5 and the second U-shaped rain shield 6.

[0022] When the inspection is completed, the worker presses the first switch 11 to activate the multi-stage electric push rod 8, retracts the first U-shaped rain shield 5 and the second U-shaped rain shield 6, and finally closes the double-leaf door 3.

[0023] It is worth noting that the rain sensor 4, the multi-stage electric push rod 8, the touch switch 13, the second switch 12, and the first switch 11 are all electrically connected to the external power grid. That is to say, the above structure is not connected to the power in the substation. Therefore, after a power failure occurs in the substation, the power transmission of the above structure can still be maintained.

[0024] In addition, the above-mentioned rain sensor 4 is an existing mature technology, especially detecting whether it is raining by the rain sensor 4 and energizing the touch switch 13 by detecting rainwater is an existing mature technology, so it will not be described in detail here.

[0025] Through the telescopic function of the first U-shaped rain shield 5 and the second U-shaped rain shield 6, and in combination with the coordinated work of the rain sensor 4, the touch switch 13, the second switch 12 and the first switch 11, the two rain shields can be automatically deployed when the double-leaf door 3 is opened. In this way, a large U-shaped protection area will be formed at both ends of the shell 1. When maintenance personnel stand in this U-shaped protection area to perform maintenance work, they can effectively avoid rain and ensure that the work proceeds smoothly. This design greatly improves the convenience and efficiency of maintenance work on rainy days.

[0026] As a preferred technical solution of the present invention, an indicator light 18 for reminding is also connected to the top inner wall of one of the door panels of the double-opening door 3.

[0027] Specifically, the setting of the indicator light 18 can facilitate workers to determine whether the rain sensor 4, the multi-stage electric push rod 8, the touch switch 13, the second switch 12, and the first switch 11 are transmitting power.

[0028] As a preferred technical solution of the present invention, a rotating groove 21 is opened on the inner wall of the first U-shaped rain shield 5, and a storage plate 9 is rotatably connected in the rotating groove 21. The outer side of the storage plate 9 is fixedly connected to a side cloth 33 and a pulling cloth 34. A pull rope 31 is fixedly connected to the top of the pulling cloth 34. The pull rope 31 passes through one end of the first U-shaped rain shield 5 and is fixedly connected to a counterweight block 30. The outer wall of the first U-shaped rain shield 5 is connected to a prying assembly for pushing the counterweight block 30 to rise and fall.

[0029] Specifically, in order to make it more convenient for workers to inspect and repair, when the first U-shaped rain shield 5 is unfolded, under the action of the prying assembly, the counterweight block 30 rises, the pull rope 31 is relaxed, and the storage plate 9 rotates to a horizontal state in the rotating groove 21. Under the action of the gravity of the storage plate 9, the counterweight block 30 stretches the pull rope 31, the side cloth 33 and the pulling cloth 34. At this time, the worker puts the tool through the opening of the side cloth 33, which is convenient for taking the tool during inspection.

[0030] Maintenance personnel can conveniently place and access maintenance tools by rotating the storage plate 9. The opening design of the storage plate 9 combines the cooperation of the counterweight block 30 and the pull rope 31, and can realize the automatic opening function without additional manual operation. Such a design not only improves work efficiency, but also simplifies the operation process, making maintenance tasks more convenient and efficient.

[0031] As a preferred technical solution of the present invention, the prying assembly includes a rack plate 36 and a gear 38. A rotating shaft 37 is rotatably connected to the first U-shaped rain shield 5. A gear 38 is fixedly sleeved on the outer end of the rotating shaft 37. The outer side of the gear 38 is meshed with a rack plate 36 fixedly connected to the inner wall of the outer shell 1. A top rod 39 is fixedly sleeved on the outer wall of the rotating shaft 37. The end of the top rod 39 abuts against the bottom surface of the counterweight block 30. The side of the counterweight block 30 away from the top rod 39 is fixedly connected to a limiting block 32. The limiting block 32 is slidably connected to the outer wall of the first U-shaped rain shield 5. The outer wall of the second U-shaped rain shield 6 close to the storage plate 9 is fixedly connected to an inclined push rod 10, and the inclined surface of the inclined push rod 10 abuts against the bottom surface of the storage plate 9.

[0032] Specifically, when the first U-shaped rain shield 5 is sliding and unfolding, it drives the rotating shaft 37 to move forward, and the gear 38 on the outside of the rotating shaft 37 will engage with the rack plate 36. As the rotating shaft 37 moves forward, the gear 38 is engaged with the rack plate 36 and rotates. The rotating shaft 37 rotates, driving the top rod 39 to rotate, so that the top rod 39 pushes the counterweight block 30 to rise. When the counterweight block 30 rises, it drives the limit block 32 to slide with the outer wall of the first U-shaped rain shield 5 to ensure that the counterweight block 30 rises and falls in a straight line. After the counterweight block 30 rises, the pull rope 31 is loosened, and the storage plate 9 rotates to a horizontal state under the action of gravity.

[0033] When the inspection is completed, the multi-stage electric push rod 8 drives the second U-shaped rain shield 6 to slide and reset, and drives the inclined push rod 10 on the outer wall of the second U-shaped rain shield 6 to slide, so that it abuts against the bottom surface of the storage plate 9, so that the inclined push rod 10 pushes the storage plate 9 to rotate, so that the second U-shaped rain shield 6 will not be restricted by the storage plate 9 when it is reset. When the second U-shaped rain shield 6 overlaps with the first U-shaped rain shield 5, the first U-shaped rain shield 5 slides on the inner wall of the outer shell 1. When the first U-shaped rain shield 5 slides, it drives the gear 38 to rotate and engage with the rack plate 36. Under the action of the fixed rack plate 36, the gear 38 rotates, which can drive the top rod 39 to rotate, so that the counterweight block 30 descends.

[0034] Through the cooperation of the rack plate 36, the gear 38, and the push rod 39, the storage plate 9 can be opened as the first U-shaped rain shield 5 slides; through the setting of the inclined push rod 10, the storage plate 9 can be closed as the second U-shaped rain shield 6 is closed.

[0035] As a preferred technical solution of the present invention, the first U-shaped rain shield 5 is located at one end of the outer wall of the outer shell 1 and is fixedly connected to a vertical plate 17. A vertical groove 24 is opened in the vertical plate 17. A moving block 26 is slidably connected in the vertical groove 24. The outer wall of the moving block 26 is fixedly connected to a lighting lamp 23, and the lighting lamp 23 is electrically connected to the touch switch 13.

[0036] Specifically, in order to make maintenance on rainy days more convenient, the outer wall of the first U-shaped rain shield 5 is also provided with a lighting lamp 23. The lighting lamp 23 can make the light line clearer during maintenance on rainy days, further improving the maintenance efficiency. In order to enable the lighting lamp 23 to be movable and to facilitate the light source to be closer to the maintenance position, the lighting lamp 23 can be slid to drive the moving block 26 to move vertically in the vertical groove 24, so that the light source can be closer to the maintenance position.

[0037] As a preferred technical solution of the present invention, a plurality of transverse grooves 25 connected to the vertical grooves 24 are provided in the vertical plate 17, and a movable block 26 is clamped in the transverse grooves 25. An extension groove 27 is provided in the end of the movable block 26 away from the transverse grooves 25, and an extension block 28 is slidably connected in the extension groove 27. The outer wall of the extension block 28 abuts against the side wall of the vertical groove 24, and a spring 29 is fixedly connected to the back of the extension block 28, and the other end of the spring 29 is fixedly connected to the inner wall of the extension groove 27.

[0038] Specifically, in order to fix the position of the moving lamp 23, after the moving block 26 moves to a certain desired position in the vertical groove 24, it can slide to the right so that the moving block 26 is stuck in the horizontal groove 25, so that the moving block 26 is stuck and will not slide downward.

[0039] When the moving block 26 is located in the transverse groove 25 , the spring 29 and the extending block 28 lose their squeezing force. At this time, under the action of the spring 29 , the extending block 28 slides out of the extending groove 27 and makes the extending block 28 abut against the side wall of the vertical groove 24 to ensure that the moving block 26 does not slide from the transverse groove 25 .

[0040] As a preferred technical solution of the present invention, two symmetrically arranged second slide grooves 15 are provided on both sides of the inner wall of the outer shell 1, and short sliders 20 corresponding to the second slide grooves 15 are fixedly connected on both sides of the outer wall of the first U-shaped rain shield 5, and a first slide groove 14 is provided on the inner wall of the first U-shaped rain shield 5, and long sliders 22 corresponding to the first slide groove 14 are fixedly connected on both sides of the outer wall of the second U-shaped rain shield 6.

[0041] Specifically, when the first U-shaped rain shield 5 is moving, it drives the short sliders 20 on both sides of its outer wall to slide with the second slide groove 15 of the outer shell 1. When the second U-shaped rain shield 6 is moving, it drives the long sliders 22 on both sides of its outer wall to slide in the first slide groove 14 on the inner wall of the first U-shaped rain shield 5. This arrangement can ensure the stability of the first U-shaped rain shield 5 and the second U-shaped rain shield 6 when sliding.

[0042] As a preferred technical solution of the present invention, two groups of symmetrically arranged third slide grooves 16 are opened on the top surface of the base 2, and the bottom surfaces of the vertical plates of the first U-shaped rain shield 5 and the second U-shaped rain shield 6 are fixedly connected with a bottom slide plate 19 corresponding to the third slide grooves 16, and a plurality of balls are rotatably embedded in the bottom surface of the bottom slide plate 19.

[0043] Specifically, when the first U-shaped rain shield 5 and the second U-shaped rain shield 6 are sliding, the bottom slide plate 19 at the bottom of the two will slide in the third slide groove 16. At the same time, under the setting of the ball, the sliding friction between the bottom slide plate 19 and the third slide groove 16 is converted into rolling friction. This setting can make the sliding of the first U-shaped rain shield 5 and the second U-shaped rain shield 6 smoother.

[0044] As a preferred technical solution of the present invention, the outer wall of the pulling cloth 34 is bonded with a wiping cloth 35 via Velcro.

[0045] Specifically, when the pulling cloth 34 is unfolded, the maintenance personnel can wipe the water stains on their hands with the outer wiping cloth 35, which can avoid the workers from wiping their hands directly with their own clothes, and the wiping cloth 35 bonded with Velcro can make it more flexible to use.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
