Description

Technical Field

[0001] The invention belongs to the technical field of prefabricated substations, in particular to a prefabricated substation. Background Art

[0002] Prefabricated substation, also known as prefabricated cabin substation or box substation, is a modern substation that integrates key electrical equipment such as high-voltage switchgear, distribution transformers, and low-voltage distribution devices into a standardized, modular prefabricated cabin. The substation is small in size and highly integrated, and is efficient, flexible, and resource-saving to use.

[0003] The patent with publication number CN116826583B discloses a modular prefabricated cabin substation, including a base frame module, an overhead support frame is arranged in the middle of the base frame module, and an inner structure module is arranged above the base frame module, a side wall module is mounted on the inner structure module, and a top cover module is arranged on the upper end of the side wall module. The inner structure module includes four groups of corner support frames, and the corner support frames are provided with lifting gears and lifting motors. The lifting gears mesh with the lifting racks on the side wall modules. The lifting motor drives the lifting gears to rotate to realize the lifting and lowering of the side wall modules, so that the interior of the substation can be completely exposed, so as to provide an open opening of sufficient size to avoid maintenance blind spots, thereby facilitating the staff to flexibly and quickly perform maintenance and repair work on the electrical equipment inside the substation.

[0004] In the above scheme, during maintenance, the lifting motor can drive the side wall frame as a whole to slide up and down along the corner support frame through the lifting gear and the lifting rack to cover and protect the internal electrical components or expose them completely. However, when the substation is installed in special areas, such as mountainous areas, the weather in the mountains is changeable and rainfall may occur at any time. Once the side wall frame is raised, the electrical components inside the substation will lose protection, and rain will directly fall on the electrical components, causing short circuits in the electrical components and other circuit failures, which not only affects the maintenance of the substation by the staff, but also causes damage to the substation. For this reason, the present invention provides a prefabricated substation. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve the technical problem is as follows: the prefabricated substation described in the present invention comprises a base, an inner structure module is fixedly installed on the base, the upper end of the inner structure module is fixedly connected to the top cover, and four sets of side panels are arranged around the inner structure module, the side panels comprise hinge blocks, the hinge blocks are fixedly connected to the upper end of the inner structure module, a main board, the middle part of the upper end of the main board is hinged to the hinge blocks, two sets of electric support rods, the upper end of the electric support rods is hinged to the main board, the inner structure module comprises four sets of corner columns, two sets of storage grooves for installing the electric support rods are opened on the corner columns, and the lower end of the electric support rod is hinged in the storage groove;

[0007] The side panels are driven by electric struts to open the inner module on all sides. The opened side panels extend to the outer sides of the inner module in an inclined posture, so that the side panels can shield the inner module and prevent rain from easily reaching the electrical components inside the inner module. This not only reduces the risk of damage to the electrical components, but also ensures that the maintenance personnel's work is not affected on rainy days.

[0008] Preferably, the main board includes a plate body, the middle part of the upper end of the plate body is hinged with the hinge block, two groups of clamping grooves are provided on the plate body, a rotating tube hinged in the clamping groove, a folding plate fixedly connected to the rotating tube, the folding plate is located in the clamping groove, a sealing rubber pad is fixedly installed on one side of the folding plate, a movable tube movably installed in the rotating tube, a spring arranged in the rotating tube, one end of the spring is close to one end of the movable tube, two groups of guide rails movably installed on the plate body, two groups of guide grooves are symmetrically provided on the plate body, the guide rails are slidably connected to the guide grooves, two groups of convex shafts are symmetrically installed on the movable tube, avoidance grooves are provided in the guide grooves, one group of convex shafts passes through the avoidance groove and is fixedly connected to the guide rails, two groups of guide grooves are provided on the rotating tube, the two groups of convex shafts respectively pass through the two groups of guide grooves, the guide grooves include spiral grooves, and the four edges of the top cover are provided with limit plates for blocking the plate body, and the convex shafts are driven along the spiral grooves to make the rotating tube rotate;

[0009] The sealing pads on the two adjacent groups of folding plates will contact in advance, so that the two adjacent groups of sealing pads are squeezed against each other, ensuring the sealing of the combined position of the two adjacent groups of folding plates. At the same time, the area between the two adjacent groups of main boards is blocked by the two groups of folding plates, so that rainwater cannot pass through the area between the two adjacent groups of main boards to reach the electrical components, further reducing the risk of damage to the electrical components.

[0010] Preferably, the side plate further comprises a piston rod, which is fixedly mounted in the rotating tube, a telescopic airbag, one end of which is fixedly connected to the bottom of the movable tube, an air pipe, one end of which is rotatably connected to the other end of the movable tube, the piston rod is movably plugged into the movable tube, and a spring sleeve is arranged on the piston rod, the guide groove further comprises a straight groove, which is connected to the spiral groove, the air pipe is laid in the inner cavity of the folding plate, and the other end of the air pipe is connected to the inside of the sealing rubber pad;

[0011] Since the two sets of sealing rubber pads are squeezed against each other in a static state, the friction between the two sets of sealing rubber pads is greatly reduced, thereby increasing the service life of the sealing rubber pads.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The side panels are driven by electric struts to open the inner module on all sides. The opened side panels extend to the outer sides of the inner module in an inclined manner, so that the side panels can shield the inner module and prevent rain from easily reaching the electrical components inside the inner module. This not only reduces the risk of damage to the electrical components, but also ensures that the maintenance personnel are not affected when working on rainy days.

[0014] 2. When the electric support rod pushes the main board to rotate, the electric support rod drives the plate body to rotate by pushing the guide rail on the main board. The plate body will release the blockage around the inner module until the plate body is blocked by the limit plate and cannot continue to rotate. At this time, the upper end of the electric support rod will continue to push the guide rail to make the guide rail slide along the guide groove. At the same time, the guide rail drives a set of cams together with the movable tube and the other set of cams to move, and the movable tube compresses the spring, and then the two sets of cams slide along the two sets of spiral grooves respectively. Since the spiral groove wall is squeezed by the cam, the rotating tube together with the folding plate and the sealing gasket rotates toward the area between the two adjacent sets of main boards until the two adjacent sets of folding plates are merged. In this process, the sealing gaskets on the two adjacent sets of folding plates will contact in advance, so that the two adjacent sets of sealing gaskets are squeezed against each other to ensure the sealing of the merged position of the two adjacent sets of folding plates. At the same time, the area between the two adjacent sets of main boards is blocked by the two sets of folding plates, so that rainwater cannot pass through the area between the two adjacent sets of main boards to the electrical components, further reducing the risk of damage to the electrical components.

[0015] 3. After the two groups of adjacent folding plates are merged, the cam is located at the intersection of the spiral groove and the linear groove. At this time, there is a small gap between the sealing pads on the two groups of adjacent folding plates. The cam is continued to be driven to move together with the movable tube, and the cam will slide along the linear groove. As the movable tube moves, the movable tube will further compress the spring, and the end of the piston rod will enter one end of the movable tube, so that the telescopic airbag in the movable tube is compressed by the end of the piston rod. The compression causes the air in the telescopic airbag to enter the sealing pad through the movable tube and the air pipe, so that the internal air pressure of the sealing pad becomes larger, and the sealing pad will expand. The expanded sealing pad blocks the gap between the two adjacent groups of sealing pads and squeezes the sealing pads to ensure the sealing of the merged part of the two groups of folding plates. Since the two groups of sealing pads are squeezed against each other in a static state, the friction between the two groups of sealing pads is greatly reduced, thereby increasing the service life of the sealing pads.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] Example: Figures 1 to 3As shown, a prefabricated substation described in an embodiment of the present invention includes a base 1, an inner structure module 2 is fixedly installed on the base 1, the upper end of the inner structure module 2 is fixedly connected to the top cover 3, and four groups of side panels 4 are arranged around the inner structure module 2, the side panel 4 includes a hinge block 402, the hinge block 402 is fixedly connected to the upper end of the inner structure module 2, a main board 401, the middle part of the upper end of the main board 401 is hinged to the hinge block 402, two groups of electric support rods 403, the upper end of the electric support rod 403 is hinged to the main board 401, the inner structure module 2 includes four groups of corner columns 201, two groups of storage grooves 202 for installing the electric support rods 403 are opened on the corner columns 201, and the lower end of the electric support rod 403 is hinged in the storage groove 202.

[0028] Specifically, in the initial state, the four groups of side panels 4 block the inner structure module 2 on all sides, and the side panels 4 are perpendicular to the base 1, and the electric support rod 403 is located in the storage groove 202 in an inclined posture. When it is necessary to inspect and repair the electrical components inside the substation, the electric support rod 403 is started, and the upper end of the electric support rod 403 will push the main board 401, so that the upper end of the main board 401 rotates around the hinge block 402 toward the outside of the inner structure module 2, so that the inner structure module 2 is opened on all sides, which is convenient for the staff to inspect and repair the electrical components inside the inner structure module 2. Compared with the prior art, the side panels 4 are driven by the electric support rod 403 to open the inner structure module 2 on all sides. The opened side panels 4 extend to the outer sides of the inner structure module 2 in an inclined posture, so that the side panels 4 shield the inner structure module 2, so that rainwater is not easy to get on the electrical components inside the inner structure module 2, which not only reduces the risk of damage to the electrical components, but also ensures that the maintenance personnel are not affected when working on rainy days.

[0029] like Figures 4 to 7As shown, the main board 401 includes a plate body 4011, the middle part of the upper end of the plate body 4011 is hinged to the hinge block 402, two sets of engaging grooves 4012 are provided on the plate body 4011, a rotating tube 4013 is hinged in the engaging groove 4012, a folding plate 4014 fixedly connected to the rotating tube 4013, the folding plate 4014 is located in the engaging groove 4012, a sealing pad 4015 is fixedly installed on one side of the folding plate 4014, an active tube 4016 is movably installed in the rotating tube 4013, a spring 4017 is arranged in the rotating tube 4013, one end of the spring 4017 is close to one end of the active tube 4016, and two sets of engaging grooves 4012 are provided on the plate body 4011. The guide rail 4018 and the plate body 4011 are symmetrically provided with two groups of guide grooves 111, the guide rail 4018 is slidably connected to the guide grooves 111, and two groups of cam shafts 161 are symmetrically installed on the movable tube 4016, and an avoidance groove 112 is provided in the guide groove 111. A group of cam shafts 161 passes through the avoidance groove 112 and is fixedly connected to the guide rail 4018, and two groups of guide grooves 131 are provided on the rotary tube 4013, and the two groups of cam shafts 161 pass through the two groups of guide grooves 131 respectively, and the guide groove 131 includes a spiral groove 31. The four edges of the top cover 3 are provided with limit plates 301 for blocking the plate body 4011, and the cam shaft 161 is driven along the spiral groove 31 to rotate the rotary tube 4013.

[0030] Specifically, after the four groups of main boards 401 are opened, the area between two adjacent groups of main boards 401 is not blocked. If it rains heavily, the rain can easily flow through the area between the two adjacent groups of main boards 401 and onto the electrical components. Therefore, when the electric support rod 403 pushes the main board 401 to rotate, the electric support rod 403 drives the plate body 4011 to rotate by pushing the guide rail 4018 on the main board 401. As the plate body 4011 rotates, the plate body 4011 will release the blockage around the inner module 2 until the plate body 4011 is blocked by the limit plate 301 and cannot continue to rotate. At this time, the upper end of the electric support rod 403 will continue to push the guide rail 4018 to make the guide rail 4018 slide along the guide groove 111, and the sliding direction is the lower attached Figure 5The middle arrow indicates the direction, and at the same time, the guide rail 4018 drives one group of cam shafts 161 together with the movable tube 4016 and the other group of cam shafts 161 to move together, and the movable tube 4016 compresses the spring 4017, and then the two groups of cam shafts 161 slide along the two groups of spiral grooves 31 respectively. Since the groove wall of the spiral groove 31 is squeezed by the cam shaft 161, the rotating tube 4013 together with the folding plate 4014 and the sealing pad 4015 rotate toward the area between the two adjacent groups of main boards 401 until the two adjacent groups of folding plates 4014 are merged. During this process, the sealing pads 4015 on the two adjacent groups of folding plates 4014 will contact in advance, so that the two adjacent groups of sealing pads 4015 are squeezed against each other to ensure the sealing of the merged position of the two adjacent groups of folding plates 4014, and at the same time, the area between the two adjacent groups of main boards 401 is blocked by the two groups of folding plates 4014, so that rainwater cannot pass through the area between the two adjacent groups of main boards 401 and fall onto the electrical components, further reducing the risk of damage to the electrical components.

[0031] like Figure 6 and Figure 8 As shown, compared with Example 1, another embodiment of the present invention is: the side panel 4 also includes a piston rod 4019, the piston rod 4019 is fixedly installed in the rotary tube 4013, a telescopic airbag 4020, one end of the telescopic airbag 4020 is fixedly connected to the bottom of the movable tube 4016, an air pipe 4021, one end of the air pipe 4021 is rotatably connected to the other end of the movable tube 4016, the piston rod 4019 is movably plugged into the movable tube 4016, and the spring 4017 is sleeved on the piston rod 4019, the guide groove 131 also includes a straight groove 32, the straight groove 32 is connected to the spiral groove 31, the air pipe 4021 is laid in the inner cavity of the folding plate 4014, and the other end of the air pipe 4021 is connected to the inside of the sealing pad 4015.

[0032] Specifically, the sealing rubber pad 4015 has good elasticity. Before the two adjacent groups of folding plates 4014 are completely merged, the corresponding two groups of sealing rubber pads 4015 will contact in advance. Since the sealing rubber pad 4015 flips over with the folding plate 4014, the two groups of sealing rubber pads 4015 will be squeezed and rubbed against each other. The friction will cause the sealing rubber pad 4015 to wear and reduce the service life of the sealing rubber pad 4015. In the initial state, the sealing rubber pad 4015 and the inside of the telescopic airbag 4020 are both filled with air. When the two adjacent groups of folding plates 4014 are merged, the convex shaft 161 is located at the intersection of the spiral groove 31 and the linear groove 32. At this time, there is a small gap between the sealing rubber pads 4015 on the two adjacent groups of folding plates 4014. The convex shaft 161 continues to be driven to move together with the movable tube 4016, and the convex shaft 161 will slide along the linear groove 32. At this time, the folding plate 4014 will not rotate, and As the movable tube 4016 moves, the movable tube 4016 will further compress the spring 4017, and the end of the piston rod 4019 will enter one end of the movable tube 4016, so that the telescopic airbag 4020 in the movable tube 4016 is compressed by the end of the piston rod 4019. The compression causes the air in the telescopic airbag 4020 to enter the sealing gasket 4015 through the movable tube 4016 and the air pipe 4021, so that the internal air pressure of the sealing gasket 4015 becomes larger, and the sealing gasket 4015 will expand. The expanded sealing gasket 4015 blocks the gap between the two adjacent groups of sealing gaskets 4015, and squeezes the sealing gaskets 4015 to ensure the sealing of the junction of the two groups of folding plates 4014. Since the two groups of sealing gaskets 4015 squeeze each other under static conditions, the friction between the two groups of sealing gaskets 4015 is greatly reduced, thereby increasing the service life of the sealing gaskets 4015.

[0033] Working principle: start the electric support rod 403, the upper end of the electric support rod 403 will push the main board 401, so that the upper end of the main board 401 rotates around the hinge block 402 toward the outside of the inner module 2, so that the inner module 2 is opened all around, which is convenient for the staff to inspect and repair the electrical components inside the inner module 2. Compared with the prior art, the electric support rod 403 drives the side panels 4 to open the inner module 2 all around. The opened side panels 4 extend to the outer sides of the inner module 2 in an inclined posture, so that the side panels 4 shield the inner module 2, so that rainwater is not easy to fall on the electrical components inside the inner module 2;

[0034] When the electric support rod 403 pushes the main board 401 to rotate, the electric support rod 403 drives the plate body 4011 to rotate by pushing the guide rail 4018 on the main board 401. As the plate body 4011 rotates, the plate body 4011 will release the blockage around the inner module 2 until the plate body 4011 is blocked by the limit plate 301 and cannot continue to rotate. At this time, the upper end of the electric support rod 403 will continue to push the guide rail 4018 to slide along the guide groove 111, and the sliding direction is the lower side. Figure 5 The middle arrow indicates the direction, and at the same time, the guide rail 4018 drives one set of convex shafts 161 together with the movable tube 4016 and the other set of convex shafts 161 to move together, and the movable tube 4016 compresses the spring 4017, and then the two sets of convex shafts 161 slide along the two sets of spiral grooves 31 respectively. Since the groove wall of the spiral groove 31 is squeezed by the convex shaft 161, the rotating tube 4013 together with the folding plate 4014 and the sealing pad 4015 rotate toward the area between the two adjacent sets of main boards 401 until the two adjacent sets of folding plates 4014 are merged. In this process, the sealing pads 4015 on the two adjacent sets of folding plates 4014 will contact in advance, so that the two adjacent sets of sealing pads 4015 are squeezed against each other to ensure the sealing of the merged position of the two adjacent sets of folding plates 4014;

[0035] When the two sets of adjacent folding plates 4014 are combined, the convex shaft 161 is located at the intersection of the spiral groove 31 and the linear groove 32. At this time, there is a small gap between the sealing rubber pads 4015 on the two sets of adjacent folding plates 4014. The convex shaft 161 is continuously driven to move together with the movable tube 4016. The convex shaft 161 will slide along the linear groove 32. At this time, the folding plates 4014 will not rotate. As the movable tube 4016 moves, the movable tube 4016 will further compress the spring 4017, and the end of the piston rod 4019 will enter one end of the movable tube 4016. The telescopic airbag 4020 in the movable tube 4016 is compressed by the end of the piston rod 4019. The compression causes the air in the telescopic airbag 4020 to enter the sealing rubber pad 4015 through the movable tube 4016 and the air pipe 4021, thereby increasing the internal air pressure of the sealing rubber pad 4015 and causing the sealing rubber pad 4015 to expand. The expanded sealing rubber pad 4015 blocks the gap between the two adjacent groups of sealing rubber pads 4015 and causes the sealing rubber pads 4015 to be squeezed to ensure the sealing of the joint of the two groups of folding plates 4014.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
