Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage power distribution cabinets, and in particular to a primary-secondary integrated high-voltage power distribution cabinet. Background Art

[0002] The primary and secondary integrated high-voltage distribution cabinet organically combines the primary ring network cabinet and the secondary equipment DTU; compared with ordinary distribution cabinets, the primary and secondary integrated high-voltage distribution cabinet has the following characteristics: 1. It adopts a plug-and-play standardized design interface. When the secondary equipment DTU needs to be replaced, it can be directly replaced with another one and connected through an aviation plug. 2. The line loss module is added, which is equivalent to realizing the monitoring function of each unit interval, which is equivalent to adding an electricity meter to realize monitoring.

[0003] The primary and secondary integrated high-voltage distribution cabinet is generally a power supply device installed outdoors or indoors, and the primary and secondary integrated high-voltage distribution cabinet is widely used. In many remote areas, electricity is relatively tight, and high-voltage distribution cabinets are needed when mechanical equipment is used for construction. Many remote areas have a lot of inclined land, so high-voltage distribution cabinets are often installed on inclined mountains. The influence of wind and rain will cause the raised soil on the mountain to weather, and the weathered soil will roll down the inclined mountain along with boulders, which will collide with the surface of the high-voltage distribution cabinet and cause damage to the high-voltage distribution cabinet. These soil and boulders will remain around the high-voltage distribution cabinet after colliding with it. When there is too much residue, it will make it easy for moisture to enter the bottom of the high-voltage distribution cabinet, affecting the controller inside it. These residual soil and boulders need to be removed after inspection by staff. At the same time, the high-voltage distribution cabinet will shake when placed. Summary of the Invention

[0004] In view of the above-mentioned deficiencies, the purpose of the present invention is to provide a primary and secondary integrated high-voltage distribution cabinet.

[0005] The present invention provides the following technical solutions:

[0006] A primary and secondary integrated high-voltage distribution cabinet, comprising: a cabinet body, rectangular frames are relatively installed on the outside of the two largest surfaces of the cabinet body, the ends of the relatively arranged rectangular frames are connected by a protective frame, and the horizontal cross-section of the protective frame is "V"-shaped, a support rod is arranged on one side of the cabinet body, and the support rod is arranged in the protective frame, the inner edge of the protective frame is fixedly connected with a plurality of limit assemblies and connected to the outside of the support rod, a protective shell is installed on the side of the end of the cabinet body deviating from the protective frame, the ends of the relatively arranged rectangular frames are connected by a curved piece, the curved piece is connected to the surface of the protective shell, and the curved piece is connected to the shell at the joint. A strain reduction component is provided, and a bottom support plate is welded to the bottom position of the cabinet, and a plurality of No. 1 embedded rods are embedded in the bottom edge of the bottom support plate, and a plurality of No. 2 embedded rods are also embedded in the bottom edge of the bottom support plate. The positions of the plurality of No. 2 embedded rods correspond one by one to the positions of the plurality of No. 1 embedded rods, and a displacement rod is embedded in the top position of the No. 2 embedded rod, and a ball is installed on the top of the displacement rod, and the ball contacts and collides with the bottom end of the rectangular frame at a right angle, and a support column is installed at the bottom of the displacement rod, and through holes are reserved on the side wall of the No. 2 embedded rod, and the through holes are evenly spaced, and an embedded module is clamped in the middle of the through hole.

[0007] As an optimal technical solution for a primary and secondary integrated high-voltage distribution cabinet, the end of the cabinet body is fixedly connected with a support plate, and the support plate is inside the protective frame. The top and bottom positions of the support plate are fixedly connected with positioning blocks, and the positioning blocks are set at a ninety-degree angle to the support plate. The head and tail of the support rod are respectively fixedly connected to the corresponding positioning blocks.

[0008] As an optimal technical solution for a primary and secondary integrated high-voltage distribution cabinet, the limiting assembly is composed of a limiting plate and a rotating ring. The rotating ring is fixedly connected to the peripheral wall of the limiting plate at equal intervals, and the rotating ring is slidably connected to the outside of the support rod. The rotating rings on the top and bottom ends of the limiting plate are docked with the positioning blocks at corresponding positions. The curved part is located at one end of the cabinet body that deviates from the protective frame, and the curved parts are distributed at equal intervals in a parallel state. The curved part, rectangular frame and protective frame rotate around the periphery of the support rod through the limiting plate and the rotating ring.

[0009] As an optimal technical solution for a primary and secondary integrated high-voltage distribution cabinet, the strain reduction component consists of a guide sleeve, a guide groove and a No. 1 spiral beryllium copper wire. The guide groove is reserved in the middle of the protective shell, the guide sleeve is fixed to the end of the curved part, and the guide sleeve is inside the guide groove. The No. 1 spiral beryllium copper wire is sleeved on the peripheral wall of the curved part, and one end of the No. 1 spiral beryllium copper wire is fixed to the end of the guide sleeve, and the other end of the No. 1 spiral beryllium copper wire is fixed to the inner edge of the guide groove.

[0010] As an optimal technical solution for a primary and secondary integrated high-voltage distribution cabinet, a reference seat is installed on the bottom peripheral wall of the bottom support plate, and the bottom support plate and the reference seat are in a parallel state. The top edge length of the bottom support plate is smaller than the bottom edge length, and the vertical cross-section of the bottom support plate is an isosceles trapezoid.

[0011] As an optimal technical solution for a primary and secondary integrated high-voltage distribution cabinet, a retaining sleeve is fixedly connected to the outer wall at the right angle of the bottom end of the rectangular frame, and the retaining sleeve and the ball are in contact with each other.

[0012] As an optimal technical solution for a primary and secondary integrated high-voltage distribution cabinet, the peripheral wall of the support column is fixedly connected with a cylinder that extends and contracts synchronously with it, and when the cylinder slides, it drives the embedded module to extend and contract. The bottom position of the support column is hooped with a No. 2 spiral beryllium copper wire, and the bottom end surface of the cylinder is milled with a No. 1 extrusion surface. The embedded module is an inclined insert plate, and the inclined insert plate can slide in the through hole. The end surface of the inclined insert plate that extends through the No. 2 embedded rod is milled with a No. 2 extrusion surface. The No. 2 extrusion surface located on the upper surface matches the inclination angle of the No. 1 extrusion surface. The other end surface of the inclined insert plate is milled with a V-shaped end. A V-shaped column is installed at the bottom position of the No. 1 embedded rod, and a V-shaped column is also installed at the bottom position of the No. 2 embedded rod. Friction protrusions are installed on the top and bottom of the inclined insert plate.

[0013] As an optimal technical solution for a primary and secondary integrated high-voltage distribution cabinet, a reserved groove is opened on the surface of one of the rectangular frames, and a rotating frame is installed in the middle of the reserved groove. The side wall of the rotating frame and the inner wall of the reserved groove are connected together by hinges.

[0014] As an optimal technical solution for a primary and secondary integrated high-voltage distribution cabinet, a protective frame is installed on the top of the cabinet body, rectangular frame and protective frame. The top surface of the protective frame is milled with a slope, and the slope is distributed in a convex shape.

[0015] As an optimal technical solution for a primary and secondary integrated high-voltage distribution cabinet, its usage is as follows:

[0016] A. When placing the cabinet, the No. 1 and No. 2 embedded rods at the bottom must be aligned with the reserved assembly slots. When rolling dirt and pebbles come into contact with the protective frame, the V-shaped surface can guide the dirt and pebbles to the sides of the cabinet, preventing them from coming into contact with the cabinet.

[0017] B. When the middle of the protective frame is hit, it will dent inward, and the ends of the protective frame will expand and rotate outward. The outward rotation of the ends of the protective frame can drive the rectangular frame to rotate, and the rectangular frame drives the curved piece to move. Because the guide sleeve is the common end connection position of the two curved pieces, and the installation of a No. 1 spiral beryllium copper wire enables the curved piece to have a blocking effect when being pulled, and the rectangular frame can also block the rotation. Ultimately, the protective frame can be immediately restored after deformation, thereby preventing damage to the protective frame by mud and pebbles;

[0018] C. The protective frame guides dirt and pebbles to the sides of the cabinet, preventing them from rolling down and remaining around the cabinet. If too much dirt and pebbles remain around the cabinet, the bottom of the cabinet will be buried. The dirt contains moisture, which can enter the cabinet through the bottom and damage the controller inside.

[0019] D. When the two ends of the protective frame deflect, the side of the rectangular frame away from the protective frame will also rotate. When the protective frame rotates, the stop sleeve at the right angle of the bottom will come into contact with the ball. At this time, the ball and the displacement rod will extend downward synchronously. Since the No. 1 extrusion surface and the No. 2 extrusion surface at the upper position are parallel, the cylinder can push the other end of the inclined insert plate into the soil during the downward pressure process. Multiple obliquely arranged inclined insert plates can make the No. 2 embedded rod and the soil plug-in position more tightly.

[0020] The beneficial effects of the present invention are:

[0021] 1. When placing and reserving the cabinet and the assembly slot, the protruding position of the middle part of the protective frame must be installed towards the mountain. When the protruding position of the middle part of the protective frame is facing the mountain, the soil and boulders rolling down from the mountain will first come into contact with the surface of the protective frame before coming into contact with the cabinet. The protruding V-shaped protective frame can block the rolling soil and boulders and guide them to the sides of the cabinet.

[0022] 2. When the middle of the protective frame is hit, the middle position will be concave inward, and the two ends of the protective frame will expand and rotate outward. When the two ends of the protective frame rotate outward, they can drive the rectangular frame to rotate, and the rectangular frame drives the curved part to move. Since the guide sleeve is the common end connection position of the two curved parts, and the No. 1 spiral beryllium copper wire is installed, the curved part can play a blocking effect when being pulled, so the rectangular frame and the protective frame can be restored immediately after the arc deformation occurs.

[0023] 3. When the two ends of the protective frame deflect, the retaining sleeve will also rotate and conflict with the ball. At this time, the ball drives the displacement rod to extend downward, and the cylinder and the inclined insert plate will be squeezed. At this time, one end of the inclined insert plate will be interfered with the soil. Multiple obliquely arranged inclined insert plates can make the No. 2 embedded rod and the soil plug-in position tighter.

[0024] 4. The V-shaped protective frame can guide the soil and pebbles to the sides of the cabinet. At this time, the rolling soil and pebbles will be guided and continue to roll down, and are not likely to remain around the cabinet. This can prevent the soil and pebbles from remaining around the cabinet. When there is too much soil and pebbles, the moisture contained in the soil and pebbles will enter the cabinet through the bottom and damage the internal controller.

[0034] Reference Figures 1 to 6 As shown, a primary and secondary integrated high-voltage distribution cabinet includes: a cabinet body 12, rectangular frames 13 are installed on the outside of the two largest surfaces of the cabinet body 12, the ends of the oppositely arranged rectangular frames 13 are connected by a protective frame 14, and the horizontal cross-section of the protective frame 14 is "V" shaped, a support rod 17 is configured on one side of the cabinet body 12, and the support rod 17 is configured in the protective frame 14, the inner edge of the protective frame 14 is fixedly connected with a plurality of limit assemblies connected to the outside of the support rod 17, and a protective shell 2 is installed on the side of the end of the cabinet body 12 away from the protective frame 14. 2. The ends of the rectangular frames 13 arranged opposite to each other are butted together by curved pieces 25, and the curved pieces 25 are located at the end of the cabinet 12 that deviates from the protective frame 14, and the curved pieces 25 are evenly spaced and arranged in a parallel state. The curved pieces 25, the rectangular frame 13, and the protective frame 14 rotate around the periphery of the support rod 17 through the limit piece 19 and the rotating ring 18. The curved pieces 25 are connected to the surface of the protective shell 22. A strain reduction component is provided at the joint between the curved pieces 25 and the protective shell 22. A bottom support plate 30 is welded to the bottom of the cabinet 12. The top side length of the bottom support plate 30 is smaller than the bottom side length, and the vertical cross-section of the bottom support plate 30 is an isosceles trapezoid. The bottom edge of the bottom support plate 30 is embedded with multiple No. 1 embedded rods 32, and the bottom edge of the bottom support plate 30 is also embedded with multiple No. 2 embedded rods 33. The positions of the multiple No. 2 embedded rods 33 correspond one by one to the positions of the multiple No. 1 embedded rods 32. The top position of the No. 2 embedded rod 33 is embedded with a displacement rod 36. The top of the displacement rod 36 is equipped with a ball 37, and the ball 37 contacts and collides with the bottom end of the rectangular frame 13 at a right angle. The displacement rod A support column 35 is installed at the bottom of 36. Through holes 40 are reserved on the side wall of the second embedded rod 33, and the through holes 40 are evenly spaced. An embedded module is clamped in the middle of the through hole 40. A cylinder 38 is fixed to the peripheral wall of the support column 35, which is synchronously extended and retracted with it. When the cylinder 38 slides, it drives the embedded module to extend and retract. A second spiral beryllium copper wire 45 is connected to the bottom of the support column 35. The second spiral beryllium copper wire 45 is located in the middle of the second embedded rod 33, and the top of the second spiral beryllium copper wire 45 contacts the bottom surface of the cylinder 38.

[0035] During work: When constructing a mountain or providing power to a remote area, the staff reserves an assembly slot at the location where the cabinet 12 needs to be placed, and places the cabinet 12 in the corresponding position. When the cabinet 12 is placed, the No. 1 embedded rod 32 and the No. 2 embedded rod 33 at the bottom thereof correspond to the reserved assembly slot. When the cabinet 12 is placed and the assembly slot at the bottom thereof is reserved, it is necessary to consider that the protruding position of the middle part of the protective frame 14 is installed toward the middle of the mountain, so that when the soil and boulders at the upper position of the mountain roll down to the surrounding of the cabinet 12, the protective frame 14 with the V-shaped protrusion in the middle corresponds to the rolling position of the soil and boulders, so that the rolled soil and boulders will collide with the protective frame 1 4 comes into contact, and the V-shaped surface can guide the soil and cobblestones to the two sides of the cabinet 12, while also reducing the contact surface of the soil and cobblestones falling on the protective frame 14, thereby reducing the degree of damage to the protective frame 14, and when the middle position of the protective frame 14 is hit, the middle position will be concave inward, and at this time, the two ends of the protective frame 14 will expand and rotate outward. When the two ends of the protective frame 14 rotate outward, they can drive the rectangular frame 13 to rotate, and the rectangular frame 13 drives the curved piece 25 to move. Since the guide sleeve 24 is the common end connection position of the two curved pieces 25, and the No. 1 spiral beryllium copper wire 26 is installed, the curved piece 25 can be pulled out of the When the protective frame 14 is deformed, it can play a blocking effect, and the rectangular frame 13 can also block the rotation, and finally the protective frame 14 can be restored immediately after deformation, thereby preventing the damage of the protective frame 14 by the soil and cobblestones, and better guiding the soil and cobblestones to the two sides of the cabinet 12, and at the same time preventing the rolling soil and cobblestones from remaining around the cabinet 12. When too much soil and cobblestones remain around the cabinet 12, the bottom of the cabinet 12 will be buried. The soil will contain moisture, and this moisture will enter the interior of the cabinet 12 through the bottom of the cabinet 12 and damage the internal controller. When the two ends of the protective frame 14 are deflected, the rectangular frame 13 is away from the protective frame 14. One side of the guard frame 14 will also rotate accordingly. When the guard frame 14 rotates, the stop sleeve 29 at the right angle position at its bottom will conflict with the ball 37. At this time, the ball 37 and the displacement rod 36 will extend downward synchronously. At this time, the displacement rod 36 drives the support column 35 to move synchronously. When the support column 35 moves, the oblique insert plate 41 will be squeezed by the cylinder 38. Since the No. 1 extrusion surface 39 is parallel to the No. 2 extrusion surface 42 at the upper position, the cylinder 38 can press the other end of the oblique insert plate 41 into the soil during the downward pressing process. Multiple obliquely arranged oblique insert plates 41 can make the No. 2 embedded rod 33 and the soil insertion position tighter, thereby preventing the cabinet body 12 from tipping over.

5. The primary and secondary integrated high-voltage distribution cabinet according to claim 1, characterized in that: A reference seat (31) is installed on the bottom peripheral wall of the bottom support plate (30), and the bottom support plate (30) and the reference seat (31) are in a parallel state. The top side length of the bottom support plate (30) is shorter than the bottom side length, and the vertical cross-section of the bottom support plate (30) is an isosceles trapezoid.

6. The primary and secondary integrated high-voltage distribution cabinet according to claim 1, characterized in that: A reserved groove is provided on the surface of one of the rectangular frames (13), and a rotating frame (27) is installed in the middle of the reserved groove. The side wall of the rotating frame (27) and the inner wall of the reserved groove are connected together through a hinge (28).

7. The primary and secondary integrated high-voltage distribution cabinet according to claim 1, characterized in that: A protective frame (20) is installed at the top of the cabinet (12), the rectangular frame (13) and the protective frame (14). A slope (21) is milled on the top surface of the protective frame (20), and the slope (21) is distributed in a convex shape.

8. The primary and secondary integrated high-voltage distribution cabinet according to claim 1, characterized in that: Here’s how to use it: A. When placing the cabinet (12), the first embedded rod (32) and the second embedded rod (33) at the bottom thereof need to be aligned with the reserved assembly groove. When the rolling soil and the cobblestone come into contact with the protective frame (14), the soil and the cobblestone can be guided to the two sides of the cabinet (12) through the V-shaped surface, and the soil and the cobblestone can be prevented from coming into contact with the cabinet (12); B. When the middle position of the protective frame (14) is hit, the middle position thereof will be concave inward, and at this time, the two ends of the protective frame (14) will expand and rotate outward. When the two ends of the protective frame (14) rotate outward, they can drive the rectangular frame (13) to rotate, and the rectangular frame (13) drives the curved member (25) to move. Since the guide sleeve (24) is the common end connection position of the two curved members (25), and the No. 1 spiral beryllium copper wire (26) is installed, the curved member (25) can play a blocking effect when being pulled, and the rectangular frame (13) can also block the rotation, and finally the protective frame (14) can be restored immediately after deformation, thereby preventing the protective frame (14) from being damaged by soil and pebbles; C. The protective frame (14) guides the soil and pebbles to the sides of the cabinet (12), and at the same time prevents the soil and pebbles from rolling down and remaining around the cabinet (12). When too much soil and pebbles remain around the cabinet (12), the bottom of the cabinet (12) will be buried. The soil contains moisture, which will enter the cabinet (12) through the bottom and damage the controller inside. D. When the two ends of the protective frame (14) are deflected, the side of the rectangular frame (13) away from the protective frame (14) will also rotate accordingly. When the protective frame (14) rotates, the stop sleeve (29) at the right angle position at the bottom thereof will come into conflict with the ball (37). At this time, the ball (37) and the displacement rod (36) will extend downward synchronously. Since the No. 1 extrusion surface (39) and the No. 2 extrusion surface (42) at the upper position are parallel, the cylinder (38) can push the other end of the oblique insert plate (41) into the soil during the downward pressing process. The multiple oblique insert plates (41) can make the No. 2 embedded rod (33) and the soil insertion position more tightly.
