Description

Technical Field

[0001] The present invention relates to the technical field of ring network cabinets, and in particular to an outdoor ring network cabinet. Background Art

[0002] A ring main unit (RMU) is a set of electrical transmission and distribution equipment housed in a metal or non-metallic insulating cabinet or an electrical equipment made into an assembled interval ring main unit. Its core parts use load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises.

[0003] At present, during the use of outdoor ring network cabinets, it is necessary to inspect and repair the electrical components inside the ring network cabinets. However, the inspection doors of the ring network cabinets all use swing doors when opening. The swing doors increase the opening range of the inspection doors, which is not convenient for sites with limited space. At the same time, the weight of the single-opening door will be concentrated on the connecting hinges, which will greatly affect the service life of the inspection door. Therefore, it is necessary to use an outdoor ring network cabinet that is easy to inspect to deal with the above problems. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the technical problem solved by the present invention is to provide an outdoor ring network cabinet to solve the problem that the maintenance range of the outdoor ring network cabinet is small during maintenance.

[0005] In order to solve the above problems, the technical solution adopted by the present invention is:

[0006] An outdoor ring network cabinet includes a box body, an opening device, a supporting device, and a sliding device. The box body is a ring network cabinet, the box body is rectangular, and the interior of the box body is hollow. An opening device is placed on the front of the box body. The opening device includes a rotating door and a sliding door. The opening device is connected to the box body and can open and close the box body. The supporting device is placed at the bottom of the box body, and the sliding device is placed at the top and bottom ends of the opening device. At the same time, the sliding device is fixedly connected to the box body.

[0007] The beneficial effects of this technical solution are:

[0008] 1. By setting up a sliding device, the inspection door can be slid during maintenance. At the same time, the sliding device has a large sliding range and does not affect the maintenance of the staff.

[0009] 2. By setting up a supporting device, the electrical components inside the ring network cabinet can be supported to avoid direct contact between the electrical components and the bottom of the ring network cabinet, so as to prevent damage to the electrical components when encountering accumulated water and debris.

[0010] Furthermore, the opening device includes two revolving doors and a sliding door. The revolving doors are arranged on the left and right sides of the front of the box body, and the sliding door is arranged in the middle of the two revolving doors. Hinges and door shafts are provided at the connection between the two revolving doors and the box body. The hinges are automatic reset hinges. The two ends of the hinges and the door shafts connect the revolving doors and the box body, so that the revolving doors can rotate around the connection with the box body, and the sliding door can slide left and right on the front of the box body. Through the combination of the revolving door and the sliding door, the opening range can be expanded while the maintenance range can be further expanded. At the same time, the use of automatic reset hinges can make the revolving door automatically close under the action of gravity.

[0011] Furthermore, sliding devices are fixedly arranged at the top and bottom of the front of the box body. The sliding devices are slide rails. The length of the slide rails is the length of the front of the box body. Pulleys are fixedly connected to the top and bottom ends of the sliding door. The pulleys are clamped and fixed in the slide rails so that the sliding door can move in the slide rails. The slide rails do not contact the rotating door, so that the sliding door and the rotating door can be closed more tightly when closing the box body.

[0012] Furthermore, the supporting device includes a horizontal plate and a vertical plate. Two horizontal plates are arranged at the bottom of the box body. The horizontal plates are placed parallel to the horizontal plane. The supporting device does not contact the bottom of the box body. The left and right ends of the horizontal plates are fixed to the inner wall of the box body by bolts. Four vertical plates are fixedly connected to the two horizontal plates. The four vertical plates evenly divide the horizontal plates. The horizontal plates and the vertical plates form a plurality of rectangular door frame structures. A plurality of bolt holes for bolts to enter are penetrated on the surface of the supporting device. The bolt holes on the supporting device can be fixed to the supporting device according to the size of the electrical components. The electrical components are placed on the rectangular frame and fixed by bolts. The supporting device places the electrical components at the bottom of the box body. The space left under the electrical components can be used to place maintenance tools during maintenance.

[0013] Furthermore, a toolbox is placed on the front side of the support device, close to the opening device. Both sides of the toolbox are connected to the vertical plates, and a handle is connected to the top of the toolbox. The toolbox is pull-out type and can be locked by pressing the toolbox to prevent the toolbox from shaking. The toolbox can be pulled out upwards by the handle, and tools can be placed in the toolbox to increase the storage space of the ring network cabinet.

[0014] Furthermore, a clamping device is placed at the bottom end of the sliding door, and the clamping device includes a clamping block and a spring column. The top of the clamping block is a wedge-shaped block. At the same time, a groove that can be clamped with the clamping block is opened at the bottom end of the middle part of the sliding door. A spring column is placed inside the clamping block. The bottom end of the spring column is fixed to the bottom end of the box body, loosened and released.

[0015] Furthermore, a pushing device is provided on the left and right sides of the clamping device, and the pushing device includes a hydraulic cylinder, an inclined block, a connecting rod and a wedge block. The inclined surface of the inclined block is higher than the slide rail, and the rotating door can squeeze the inclined block when closing. A connecting rod is connected to the bottom end of the inclined block, and the connecting rod extends downward. The connecting rod is placed in the hydraulic cylinder, and hydraulic oil is placed in the hydraulic cylinder. An output rod is connected to the other end of the hydraulic cylinder. A spring is provided on one side of the output rod in the hydraulic cylinder, and the spring connects the output rod and the side wall of the hydraulic cylinder. A wedge block is fixedly connected to the other end of the output rod. The connecting rod and the output rod form a piston-like structure in the hydraulic cylinder. When the rotating door is opened, the rotating door will move forward under the rotation of the hinge. When the door is closed, the inclined block is pushed downward by the spring in the hydraulic cylinder, thereby releasing the clamping state of the clamping block and pushing the sliding door back and forth so that the groove at the bottom of the sliding door is disengaged from the clamping block. When closing the sliding door, the sliding door is moved back and forth so that the spring column is clamped in the groove at the bottom of the sliding door. When the spring column bounces up and clamps the sliding door, a "click" sound is produced. The operator uses this to judge whether the sliding door is clamped in place and then closes the rotating door. When the rotating door is closed, it squeezes the inclined block to move downward, thereby pushing the output shaft in the hydraulic cylinder, pushing the wedge block to clamp in the groove of the clamping block, clamping the clamping block, and making the sliding door clamped and unable to move.

[0016] Furthermore, multiple heat dissipation holes are opened on the surface of the rotating door. The heat dissipation holes are rectangular and arranged in a rectangular shape. The additional heat dissipation holes can discharge and cool down the high temperature generated by the electrical components inside the ring network cabinet, thereby avoiding damage to the components inside the ring network cabinet due to high temperature.

[0017] Furthermore, the two revolving doors and the sliding door are not in the same plane. An acrylic billboard is placed between the two revolving doors by bolts. In the closed state, the billboard covers the sliding door. The billboard and the sliding door are connected as one. The billboard and the two revolving doors are in the same plane. The acrylic billboard is detachable. Placing the acrylic billboard can prevent debris from entering the sliding rail of the sliding door and hindering the sliding effect of the sliding door, while also increasing the aesthetics.

[0025] The embodiment is basically as shown in the attached Figure 1 As shown:

[0026] An outdoor ring network cabinet, as shown in the attached Figure 1 Shown and attached Figure 2 As shown, it includes a box body 1, an opening device, a supporting device and a sliding device. The box body 1 is a rectangular ring network cabinet. The interior of the box body 1 is hollow. The opening device is placed on the front of the box body 1. The supporting device and the sliding device are placed inside the box body 1. The opening device includes two rotating doors 2 and a sliding door 3. The two rotating doors 2 are respectively connected to the box body 1. The two rotating doors 2 are connected to the box body 1 through hinges. The hinges are gravity-type automatic reset hinges. When the hinges rotate, they can drive the rotating doors down under the action of gravity. As shown in the attached figure Figure 2 As shown, the two rotating doors 2 and the sliding door 3 are not in the same plane, so that the two rotating doors 2 can rotate around the rotation center of the hinge. At the same time, there is a sliding door 3 between the two rotating doors 2. The top and bottom ends of the sliding door 3 are connected with slide rails 9. The other side of the slide rails 9 is fixed to the box body 1, so that the sliding door 3 can slide parallel to the front of the box body 1. The slide rails 9 do not contact the rotating doors 2, so that the sliding door 3 can move laterally alone. A plurality of heat dissipation holes 1-1 are provided on the two rotating doors 2. The heat dissipation holes 1-1 are rectangular; as shown in the attached Figure 2 As shown, a supporting device is fixed at the bottom end of the box body 1, and the supporting device includes two horizontal plates 5 and four vertical plates 4. The two ends of the two horizontal plates 5 are fixed to the inner wall of the box body 1 by bolts. Four vertical plates 4 are arranged on the horizontal plates 5. The four vertical plates 4 divide the two horizontal plates 5 into three rectangular door frame-like structures. A plurality of bolt holes 6 are opened on the supporting device, and bolts are placed in the bolt holes 6. Electrical components are placed on the supporting device, and the electrical components are fixed to the supporting device by bolts passing through the bolt holes 6. A certain space is left below the supporting device, and a tool box 7 is arranged in the box body. Maintenance tools are placed in the tool box 7, and the tool box 7 can be pulled upward and lifted. The tool box 7 is a pull-out box body 1, and the height of the tool box 7 is consistent with the space leaked below the supporting device; as shown in the attached figure Figure 3As shown, a clamping device and a pushing device are provided at the bottom of the box body. The pushing device is symmetrically arranged at the left and right sides of the bottom center of the box body 1. The clamping device includes a connecting rod 2-6, a hydraulic cylinder 2-3, an inclined block 2-2, and a wedge block 2-5. The inclined surface of the inclined block 2-2 is higher than the slide rail 8. The rotating door 2 can squeeze the inclined block 2-2 when closing. A connecting rod 2-6 is connected to the bottom end of the inclined block 2-2. The connecting rod 2-6 extends downward and is placed in the hydraulic cylinder 2-3. The bottom of the connecting rod 2-6 is connected to the hydraulic cylinder 2-3. The bottom end of the connecting rod 2-6 is connected to a card plate. The connecting rod 2-6 can push the card plate in the hydraulic cylinder 2-3 to form a piston-like structure. The other end of the cylinder 2-3 is connected to the output rod 2-4, the output rod 2-4 extends into the hydraulic cylinder 2-3 and is connected to a card plate. When the connecting rod 2-6 moves in the hydraulic cylinder 2-3, the output rod 2-4 can also move in the hydraulic cylinder 2-3. A wedge 2-5 is fixedly connected to the other end of the output rod 2-4. The wedge 2-5 is trapezoidal in shape. By rotating the rotary door 2, the rotary door 2 is opened under the action of the hinge 2-1. At this time, the oblique block 2-2 moves upward, thereby driving the spring in the hydraulic cylinder 2-3 to restore its deformation, driving the output rod 2-4 and the wedge 2-5 to disengage from the clamping groove of the clamping block 2-7, releasing the clamping state of the clamping block 2-7, and then the sliding door 3 can be pushed; as shown in the attached figure Figure 4 As shown, the clamping device includes a clamping block 2-7 and a spring column 2-8. The spring column 2-8 is arranged in the clamping block 2-7. The bottom end of the spring column 2-8 is fixed to the bottom of the box body 1. The clamping block 2-7 is not fixed to the box body 1, but is only connected to the spring column 2-8. At the same time, there are clamping grooves on the left and right sides of the clamping block 2-7. The wedge block 2-5 can be embedded in the clamping groove of the clamping block 2-7 to clamp and fix the clamping block 2-7. A groove is opened in the middle of the bottom end of the sliding door 3. The clamping block 2-7 can be embedded in the groove at the bottom end of the sliding door 3 to limit and clamp the sliding door 3.

[0027] Since the two rotating doors 2 and the one sliding door 3 are not in the same plane, an acrylic billboard 3-1 is placed on the outside of the sliding door 3 by bolts. The acrylic billboard 3-1 and the two rotating doors 2 are in the same plane. While increasing the aesthetics, it also blocks the gap between the sliding door 3 and the rotating door 2 to prevent debris from entering the gap and affecting the sliding effect of the sliding door 3.

[0028] The specific implementation process is as follows:

[0029] When it is necessary to inspect and repair the outdoor ring network cabinet, the staff will open the left and right rotating doors 2, and the door shaft will move downward under the action of the hinge 2-1. At the same time, the inclined block 2-2 will bounce upward under the action of the spring in the hydraulic cylinder 2-3, and the output rod 2-4 will drive the wedge block 2-5 to move, so that the wedge block 2-5 will be separated from the clamping block 2-7. At this time, the sliding door 3 is pushed. Under the action of the spring column 2-8, the groove at the bottom of the sliding door 3 is separated from the clamping block 2-7. At this time, the tool box 7 is lifted up, and the maintenance tools are taken out to complete the maintenance of the electrical components. When the maintenance is completed, the sliding door 3 is pushed, and the clamping block 2-7 is retracted. Under the action of the spring column 2-8, it bounces upward, passes through the groove at the bottom of the sliding door 3 and is clamped. The clamping block 2-7 will make a "click" sound when it bounces up and clamps the sliding door 3. The maintenance personnel can judge whether the sliding door 3 is clamped in place by pushing the sliding door 3 or the sound. Then the two rotating doors 2 are automatically closed under the action of the hinge 2-1. At this time, the inclined block 2-2 is pressed downward by the rotating door 2. The inclined block 2-2 drives the transmission rod to move in the hydraulic chamber, and then drives the output rod 2-4 and the wedge block 2-5 to be clamped in the groove of the clamping block 2-7, clamping the clamping block 2-7. At this time, pushing the sliding door 3 cannot be pushed open.

[0030] The above is only an embodiment of the present invention, and the common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
