Description

Technical Field

[0001] This application relates to the technical field of JP cabinets, and in particular to a column-mounted JP cabinet that is easy to maintain. Background Technology

[0002] The integrated distribution cabinet of the distribution transformer, abbreviated as JP cabinet, is an outdoor integrated distribution device for low-voltage power distribution systems. It is usually made of stainless steel or galvanized steel plate cabinet and is mainly suitable for rural power grid transformation, urban power grid transformation, residential communities and other scenarios.

[0003] In related technologies, the JP cabinet includes a cabinet body, a placement slot for placing electrical components is provided inside the cabinet body, and a cabinet door for sealing the placement slot is rotatably connected to the cabinet body.

[0004] JP cabinets are typically installed on a mounting frame between two utility poles. When workers need to inspect the electrical components inside the JP cabinet, the open cabinet door lacks a fixed structure and is easily affected by strong winds, causing it to rotate and interfering with the inspection process. Summary of the Invention

[0005] To address the issue of the cabinet door failing to secure itself when opened, this application provides a column-mounted JP cabinet that is easy to maintain.

[0006] This application provides a column-mounted JP cabinet that is easy to maintain, and adopts the following technical solution:

[0007] A column-mounted JP cabinet for easy maintenance includes a cabinet body with a placement slot for electrical components inside. A cabinet door for sealing the placement slot is rotatably connected to the cabinet body. A rotating shaft is provided on the cabinet body, and the cabinet door is rotatably connected to the rotating shaft. A first elastic element is provided on the cabinet door, and a fixing block is provided on the first elastic element. The first elastic element is used to drive the fixing block to move towards the rotating shaft. A fixing hole for the fixing block to be inserted is provided on the rotating shaft. A sliding rod is slidably connected in the fixing hole, and the sliding rod is used to drive the fixing block to disengage from the fixing hole. When the cabinet door is opened to a certain angle, the fixing block is inserted into the fixing hole. When the sliding rod is fully inserted into the fixing hole, the fixing block disengages from the fixing hole.

[0008] By adopting the above technical solution, when the cabinet door is opened and moved to a certain angle, the fixing block is inserted into the fixing hole to fix the cabinet door and the rotating shaft, preventing the cabinet door from rotating due to strong winds, thus keeping the cabinet door open and reducing the possibility of the cabinet door rotating and interfering with the maintenance process of the staff; after the staff has finished the maintenance, the staff will fully insert the sliding rod into the fixing hole, and the sliding rod will drive the fixing block to disengage from the fixing hole, so that the cabinet door and the rotating shaft are unlocked, and the staff can close the cabinet door.

[0009] Optionally, a locking block is slidably connected to the cabinet door, and the locking block has a movable groove for a fixing block to be inserted and slid. The cabinet door is provided with a switching structure for driving the locking block to move along the length of the rotating shaft. The rotating shaft has a fixing groove for the fixing block to be inserted. The wall of the fixing groove has a guide slope, and the distance from the guide slope to the fixing groove gradually decreases along the direction of the fixing block insertion into the fixing groove axis.

[0010] By adopting the above technical solution, when the cabinet door is closed, the switching structure drives the locking block to move along the length of the pivot, allowing the fixing block to be inserted into the fixing slot. This further strengthens the fixation of the cabinet door to the pivot, reduces the possibility of the cabinet door detaching from the cabinet, and allows the cabinet door to more stably seal the placement slot, enhancing the overall stability of the cabinet during transportation. After the cabinet is installed, the switching structure stops driving the locking block to move closer to the ground, allowing the fixing block to smoothly and autonomously disengage from the fixing slot along the inclined direction of the guide slope, thereby releasing the lock between the cabinet door and the cabinet and allowing the cabinet door to be opened.

[0011] Optionally, the switching structure includes a lifting ring and a second elastic element. The cabinet has a through hole for inserting the lifting ring, and an internal thread is provided in the through hole. The lifting ring has an external thread corresponding to the internal thread. The lifting ring is used to drive the locking block to move towards the ground. The second elastic element is provided on the locking block and is used to drive the locking block to move away from the ground.

[0012] By adopting the above technical solution, when workers need to install the cabinet, they first thread the lifting ring into the through hole, and then drive the locking block to move closer to the ground, so that the fixing block can be inserted into the fixing groove, locking the cabinet door and the hinge, reducing the possibility of the cabinet door opening during installation. Workers can use the lifting ring to lift the cabinet, providing convenience for the installation process. After the cabinet is installed, workers remove the lifting ring to prevent it from being corroded by wind and sun, thus extending its service life. The second elastic element drives the locking block to move away from the ground, allowing the fixing block to disengage from the fixing groove along the inclined direction of the guide slope, thereby unlocking the fixation between the cabinet door and the cabinet.

[0013] Optionally, multiple lifting rings are provided, and the cabinet door has a receiving slot for inserting the lifting rings. Multiple receiving slots are provided and distributed horizontally. When multiple lifting rings are inserted into their corresponding receiving slots, the tool can be placed above the multiple lifting rings.

[0014] By adopting the above technical solution, the staff can remove multiple lifting rings and insert them into the corresponding receiving slots, so that the multiple lifting rings can be arranged and extended horizontally. When the staff are inspecting the electrical components inside the cabinet, they can place their tools on top of the multiple lifting rings, providing space for the staff to place their tools and facilitating the process of inspecting the cabinet.

[0015] Optionally, a sealing element is detachably connected within the receiving groove, and the sealing element can be inserted into the through hole; when the sealing element is inserted into the through hole, the sealing element seals the through hole.

[0016] By adopting the above technical solution, a sealing element is detachably connected inside the receiving groove. After the cabinet is installed, the worker can remove the lifting ring and insert it into the receiving groove for placement. The sealing element is also removed and inserted into the through hole to seal the through hole where the lifting ring is not installed, preventing impurities or rainwater from entering the through hole. At the same time, by exchanging the positions of the lifting ring and the sealing element, suitable placement space is provided for both, reducing the possibility of loss of the lifting ring and the sealing element.

[0017] Optionally, the cabinet body is provided with a limiting groove communicating with the through hole, and the sealing element is provided with an elastic limiting block; when the sealing element is inserted into the through hole, the limiting block is inserted into the limiting groove, and the limiting block deforms.

[0018] By adopting the above technical solution, when the seal is inserted into the through hole, the limiting block is inserted into the limiting groove, and the limiting block deforms, so that the seal can fill and seal in the limiting groove. Compared with the through hole with threads, the limiting groove causes less wear on the seal, and the seal can better seal the through hole, thereby extending the service life of the seal.

[0019] Optionally, a support frame is rotatably connected to the cabinet door, the receiving groove is formed on the support frame, and a stop block is slidably connected to the cabinet door. The stop block is used to prevent the support frame from rotating towards the cabinet door. When the stop block abuts against the surface of the support frame near the cabinet door, the receiving groove extends in the horizontal direction.

[0020] By adopting the above technical solution, a support frame is rotatably connected to the cabinet door. The operator can slide the stop block onto the rotation path of the support frame to fix the support frame, so that the receiving slot can extend horizontally. This allows the lifting ring to be inserted into the receiving slot to provide space for tool placement. When the cabinet door needs to be closed, the operator can rotate the support frame to place the lifting ring against the cabinet door, reducing the space occupied by the lifting ring.

[0021] Optionally, the support frame is provided with a slot for inserting a stop block. When the support frame is rotated to the surface of the cabinet door, the stop block can be inserted into the slot, and the support frame is fixed to the cabinet door.

[0022] By adopting the above technical solution, when the support frame rotates to the surface of the cabinet door, the staff inserts the stop into the slot to fix the support frame and the cabinet door. The stop can restrict the rotation of the support frame, reduce the possibility of the support frame rotating during the opening or closing of the cabinet door, thereby reducing the collision between the support frame and the cabinet door and enhancing the overall stability of the cabinet.

[0023] Optionally, the slide bar is provided with a spring block, which abuts against the wall of the fixing hole, and the spring block is used to restrict the slide bar from sliding in the fixing hole.

[0024] By adopting the above technical solution, the spring block abuts against the wall of the fixed hole, causing the spring block to deform in the fixed hole, thereby applying force to the wall of the fixed hole and restricting the sliding rod from sliding in the fixed hole. This reduces the possibility of the sliding rod being accidentally touched and causing the fixed block to disengage from the fixed hole. The operator needs to apply a certain force to slide the sliding rod, and the first elastic element has sufficient driving force to overcome the resistance of the spring block to drive the fixed block to push the sliding rod.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When the cabinet door is opened to an angle, the fixing block is inserted into the fixing hole to fix the cabinet door and the pivot, preventing the cabinet door from rotating due to strong winds and keeping the cabinet door open. This reduces the possibility of the cabinet door rotating and interfering with the maintenance process. After the maintenance is completed, the staff fully inserts the sliding rod into the fixing hole, and the sliding rod drives the fixing block to disengage from the fixing hole, thereby releasing the lock between the cabinet door and the pivot and allowing the staff to close the cabinet door.

[0027] 2. When the cabinet door is closed, the switching mechanism drives the locking block to move along the length of the pivot, allowing the fixing block to insert into the fixing slot. This further strengthens the fixation of the cabinet door to the pivot, reduces the possibility of the cabinet door detaching from the cabinet, and allows the cabinet door to more stably seal the placement slot, enhancing the overall stability of the cabinet during transportation. After the cabinet is installed, the switching mechanism stops driving the locking block to move closer to the ground, allowing the fixing block to smoothly and autonomously disengage from the fixing slot along the inclined direction of the guide slope, thus releasing the lock between the cabinet door and the cabinet and allowing the cabinet door to open.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0035] This embodiment discloses a column-mounted JP cabinet that is easy to maintain. (Refer to...) Figure 1 and Figure 2 A column-mounted JP cabinet for easy maintenance includes a cabinet body 1. The cabinet body 1 has a placement slot 11 for storing electrical components. A rotating shaft 3 is fixedly connected inside the cabinet body 1. A cabinet door 2 for sealing the placement slot 11 is rotatably connected to the outer surface of the rotating shaft 3. The cabinet door 2 has a mounting groove 26 communicating with the rotating shaft 3, extending along the length of the rotating shaft 3. A locking block 22 is slidably connected within the mounting groove 26. A movable groove 221 is formed on the surface of the locking block 22 near the rotating shaft 3.

[0036] Reference Figure 2A first elastic element 21 is fixedly connected to the bottom wall of the movable groove 221. A fixing block 211 is fixedly connected to the end face of the first elastic element 21 near the rotating shaft 3. The first elastic element 21 is used to drive the fixing block 211 to move towards the rotating shaft 3. A fixing hole 31 for the fixing block 211 to be inserted is opened on the outer surface of the rotating shaft 3. The fixing hole 31 extends radially through the rotating shaft 3. A slide rod 32 is slidably connected in the fixing hole 31. The slide rod 32 is L-shaped. The length of one side of the slide rod 32 is equal to the length of the fixing hole 31. The other side of the slide rod 32 extends out of the rotating shaft 3. The slide rod 32 is used to drive the fixing block 211 to disengage from the fixing hole 31.

[0037] Reference Figure 2 A spring block 321 is fixedly connected to the outer surface of the sliding rod 32 located in the fixing hole 31. The spring block 321 abuts against the hole wall of the fixing hole 31 and is in a deformed state. The spring block 321 is used to limit the sliding rod 32 from sliding in the fixing hole 31. The first elastic element 21 can overcome the resistance of the spring block 321 to drive the fixing block 211 to be inserted into the fixing hole 31. The operator needs to apply a certain force to push the sliding rod 32 to reduce the occurrence of the sliding rod 32 being accidentally touched and causing the fixing block 211 to disengage from the fixing hole 31.

[0038] Reference Figure 2 When the staff opens cabinet door 2, the fixing block 211 slides along the circumferential outer surface of the rotating shaft 3. The first elastic element 21 drives the fixing block 211 to move closer to the rotating shaft 3, allowing it to insert into the fixing hole 31 when the cabinet door 2 is opened to a certain angle. This secures the cabinet door 2 and the rotating shaft 3, preventing the cabinet door 2 from rotating due to external force. After maintenance, the staff fully inserts the sliding rod 32 into the fixing hole 31, driving the fixing block 211 out of the fixing hole 31, thus unlocking the cabinet door 2 from the rotating shaft 3.

[0039] Reference Figure 3 The cabinet door 2 is provided with a switching structure 23 for driving the locking block 22 to move along the length of the rotating shaft 3. The switching structure 23 includes a lifting ring 231 and a second elastic element 232. The lifting ring 231 is detachably connected to the cabinet body 1, and the second elastic element 232 is fixedly connected to the inside of the cabinet door 2. A through hole 12 for inserting the lifting ring 231 is opened on the surface of the cabinet body 1 away from the ground, and a through hole 27 for inserting the lifting ring 231 is opened on the surface of the cabinet door 2 away from the ground. The through hole 27 communicates with the mounting groove 26. Internal threads are opened on the inner surfaces of the through hole 12 and the through hole 27, and external threads corresponding to the internal threads are opened on the outer surface of the lifting ring 231.

[0040] Reference Figure 3When cabinet door 2 is closed, through hole 12 and through hole 27 are aligned. The lifting ring 231 is threaded into through hole 12 and through hole 27 to lock cabinet door 2 and cabinet body 1, making it easier for staff to hoist cabinet body 1 into the air for installation.

[0041] Reference Figure 3 The mounting groove 26 has a receiving groove 261 on the groove wall near the ground. The second elastic member 232 is fixedly connected to the bottom wall of the receiving groove 261. The end face of the second elastic member 232 away from the receiving groove 261 is fixedly connected to the locking block 22. The second elastic member 232 is used to drive the locking block 22 to move away from the ground.

[0042] Reference Figure 3 The outer surface of the rotating shaft 3 is provided with a fixing groove 33 for the fixing block 211 to be inserted. The fixing groove 33 is staggered with the fixing hole 31, and the fixing groove 33 is located on the side of the fixing hole 31 closer to the ground. When the cabinet door 2 is closed, the fixing groove 33 is connected to the mounting groove 26. The locking block 22 is driven to move towards the ground by the lifting ring 231, so that the fixing block 211 is disengaged from the horizontal plane of the fixing hole 31, and the horizontal plane of the fixing block 211 and the fixing groove 33 are flush.

[0043] Reference Figure 3 The fixing groove 33 has guide slopes 331 on both the groove wall near and away from the ground. The distance from the guide slope 331 to the axis of the fixing groove 33 gradually decreases along the direction in which the fixing block 211 is inserted into the fixing groove 33. When the lifting ring 231 disengages from the through hole 12 and the through hole 27, the second elastic element 232 can drive the fixing block 211 to disengage from the fixing groove 33 along the inclined direction of the guide slope 331, thereby unlocking the cabinet door 2 and the cabinet body 1.

[0044] Reference Figure 1 and Figure 3 Multiple through holes 12 are provided, and the multiple through holes 12 are distributed along the four corners of the circumference of the cabinet 1. The number of hanging rings 231 is the same as the number of through holes 12.

[0045] Reference Figure 1 and Figure 4 A support frame 24 is rotatably connected to the inner surface of the cabinet door 2. Multiple receiving slots 241 are provided on the surface of the support frame 24 away from the cabinet door 2, arranged in an array along the length of the support frame 24. When all the receiving slots 241 are inserted into their corresponding receiving slots 241, the operator rotates the support frame 24 to be perpendicular to the cabinet door 2. At this point, all the receiving slots 231 extend horizontally, allowing the operator to place tools above them for easy inspection and repair of the electrical components inside the cabinet 1.

[0046] Reference Figure 4A sliding groove 25 is formed on the inner surface of the cabinet door 2, extending along the length of the support frame 24. A stop block 251 is slidably connected within the sliding groove 25. The stop block 251 is L-shaped, and a slot 242 for inserting the stop block 251 is formed on the side of the support frame 24. When the stop block 251 is located on the side of the support frame 24 closest to the ground and abuts against the surface of the support frame 24 closest to the cabinet body 1, the support frame 24 is perpendicular to the inner surface of the cabinet body 1. At this time, the receiving groove 241 extends horizontally, and the lifting rings 231 within the receiving groove 241 are distributed horizontally. When the support frame 24 rotates to the surface of the cabinet door 2, the stop block 251 can be inserted into the slot 242 to fix the support frame 24 to the inner surface of the cabinet door 2, reducing the possibility of the support frame 24 rotating.

[0047] Reference Figure 4 and Figure 5 A sealing element 13 is detachably connected within the receiving groove 241. The sealing element 13 is elastic and can be inserted into the through hole 12. A limiting groove 121 communicating with the through hole 12 is formed on the surface of the cabinet 1 away from the ground. A limiting block 131 is fixedly connected to the outer surface of the sealing element 13, and the limiting block 131 is arranged around the circumferential outer surface of the sealing element 13. The limiting groove 121 is used for the insertion of the limiting block 131. After the cabinet 1 is installed, the worker removes the lifting ring 231 from the through hole 12 and inserts it into the receiving groove 241 to reduce the possibility of the lifting ring 231 rusting or being damaged due to prolonged exposure to the outside of the cabinet 1, thus protecting the lifting ring 231. At the same time, the worker inserts the sealing element 13 into the through hole 12, and the limiting block 131 can be inserted into the limiting groove 121, and the limiting block 131 deforms to achieve a seal between the sealing element 13 and the through hole 12.

[0048] The implementation principle of a column-mounted JP cabinet that is easy to maintain according to an embodiment of this application is as follows: When the staff needs to hoist the cabinet 1, the staff first threadedly connects multiple lifting rings 231 into the through holes 12. The lifting rings 231 drive the locking block 22 to move towards the ground. The first elastic element 21 inserts the fixing block 211 into the fixing groove 33. At this time, the rotating shaft 3 and the cabinet door 2 are locked to prevent the cabinet 1 from opening by itself during the installation process. After the cabinet 1 is installed, the staff first removes the lifting rings 231. At this time, the second elastic element 21... Under the force of the elastic element 232, the fixing block 211 disengages from the fixing groove 33 along the inclined direction of the guide slope 331. The staff opens the cabinet door 2 to a certain angle, so that the first elastic element 21 drives the fixing block 211 to insert into the fixing hole 31. At this time, the cabinet door 2 is fixed on the rotating shaft 3. The staff then removes the sealing element 13 on the support frame 24 and inserts it into the through hole 12 to seal the through hole 12. At the same time, the staff installs multiple lifting rings 231 in the corresponding receiving grooves 241 to complete the storage of multiple lifting rings 231.
