Description

Technical Field

[0001] The present application relates to the technical field of power distribution cabinets, and in particular to a low-voltage power distribution cabinet. Background Art

[0002] Low-voltage distribution cabinet is an electrical equipment widely used in power systems. It undertakes the important tasks of power distribution, control, protection and monitoring. Low-voltage distribution cabinet can be installed indoors and outdoors.

[0003] In the related art, a low-voltage power distribution cabinet includes a cabinet body and a cabinet door. The cabinet door is rotatably connected to the cabinet body. A receiving slot is provided on the cabinet body. Electrical components are arranged in the receiving slot. The electrical components are used to realize the basic functions of the low-voltage power distribution cabinet.

[0004] Since the low-voltage distribution cabinet is installed outdoors, it may encounter windy and sandy weather. At this time, wind and sand may enter the cabinet from the gap between the cabinet door and the cabinet body, allowing the sand and dust to affect the electrical components in the cabinet. Summary of the invention

[0005] In order to improve the problem that wind and sand easily enter the interior of the cabinet through the gap between the cabinet door and the cabinet body, the present application provides a low-voltage power distribution cabinet.

[0006] The present application provides a low-voltage power distribution cabinet, which adopts the following technical solution:

[0007] A low-voltage power distribution cabinet comprises a cabinet body and a cabinet door, wherein the cabinet door is rotatably connected to the cabinet body, a receiving groove is provided on the cabinet body, a baffle is provided on the cabinet body, and the baffle extends along the circumference of the receiving groove. When the cabinet door blocks the receiving groove, the baffle abuts against the cabinet door.

[0008] By adopting the above technical solution, the baffle is extended along the circumference of the receiving groove, so that the baffle is used to block the cabinet door and the cabinet body, so that the wind and sand are restricted by the baffle, and the wind and sand cannot be directly blown into the receiving groove from the gap between the cabinet door and the cabinet body, thereby reducing the impact of the wind and sand entering the receiving groove on the electrical components, so that the distribution cabinet can operate normally in a windy and sandy climate; at the same time, when the cabinet door is impacted, the cabinet door abuts against the baffle, so that the baffle can provide a certain support and buffering effect, thereby reducing the risk of damage to the cabinet door.

[0009] Optionally, a stopper is provided on the cabinet door, and when the cabinet door blocks the accommodating groove, the stopper abuts against the baffle.

[0010] By adopting the above technical solution, when the weather is hot, the cabinet door is usually made of metal, and the cabinet door may produce some small range of expansion, making it difficult for the cabinet door and the baffle to completely abut against each other. The block abuts against the baffle, reducing the deformation of the cabinet door and causing a gap between the cabinet door and the baffle, allowing the baffle and the block to abut more stably, further reducing the possibility of wind and sand entering the receiving slot, and enhancing the safety inside the distribution cabinet.

[0011] Optionally, a receiving groove is provided on the cabinet body, and a rain shield is slidably connected to the receiving groove. When the cabinet door blocks the receiving groove, the cabinet door is located on a side of the rain shield away from the bottom wall of the receiving groove.

[0012] By adopting the above technical solution, the cabinet door is located on the side of the rain shield away from the bottom wall of the accommodating groove, so that the rain shield will not slide out of the accommodating groove directly, and the rain shield can be stably located in the accommodating groove; when it rains or the weather is hot, people open the cabinet door and pull the rain shield to allow the rain shield to cover the top of people, reducing the impact of hot weather or rain, that is, rainwater is not easy to directly enter the accommodating groove, allowing people to perform maintenance work on the distribution cabinet for a long time, reducing the impact of weather on staff when repairing electrical components.

[0013] Optionally, a limiting groove is provided on the rain shield, a limiting spring is provided in the limiting groove, a limiting block is provided on the limiting spring, and a through hole is provided on the cabinet door for inserting the limiting block. When the limiting block is inserted into the through hole, the rain shield is fixed on the cabinet door.

[0014] By adopting the above technical solution, the limit block is driven by the limit spring to be inserted into the through hole, so that the hole wall of the through hole limits the limit block, and the limit block fixes the cabinet door, so that the cabinet door and the rain shield are fixed to each other, reducing the possibility of the rain shield moving in the accommodating groove, so that the staff does not need to manually fix the rain shield. The staff only needs to pull the rain shield to the appropriate position to fix the rain shield.

[0015] Optionally, an operating bar is slidably connected to the through hole, and when the operating bar is completely located in the through hole, the limiting block is separated from the through hole.

[0016] By adopting the above technical solution, the operating strip slides in the through hole, so that the operating strip drives the limit block to disengage from the through hole, so that the cabinet door does not fix the rain shield, and the rain shield can slide freely in the accommodating groove, so that the staff can move the rain shield completely into the accommodating groove; at the same time, the operating strip is located on the side of the cabinet door away from the rain shield, which makes it difficult for the staff to touch the operating strip when repairing the distribution cabinet, thereby reducing the situation where the staff accidentally touches the operating strip during the repair process, resulting in the rain shield being unable to be fixed, thereby increasing the reliability of the rain shield.

[0017] Optionally, an observation door is rotatably connected to the cabinet body, and the observation door is located on the side of the cabinet door facing the bottom wall of the accommodating groove. The observation door is provided with an observation glass for observing the accommodating groove. The observation door is provided with a locking groove, and a locking strip for inserting into the locking groove is slidably connected to the cabinet body. When the locking strip is located in the locking groove, the observation door is fixed to the cabinet body.

[0018] By adopting the above technical solution, an observation glass is provided on the observation door, and the observation door is located on the side of the cabinet door facing the bottom wall of the receiving groove, so that the staff does not need to touch the electrical components during daily inspections, but only needs to open the cabinet door and observe the inside through the observation glass. The blocking of the observation door reduces the damage caused by the staff accidentally touching the electrical components, thereby improving the safety performance of the distribution cabinet; the locking bar is inserted into the locking groove, and the groove wall of the locking groove limits the locking bar, so that the observation door can be fixed on the cabinet body, reducing the situation of accidental unlocking of the observation door and increasing the reliability of the observation door; at the same time, the staff first opens the cabinet door, then pulls the rain shield, and finally turns the observation door. By providing an observation glass on the observation door, when the cabinet door and the rain shield are opened, the observation door can block the receiving groove, reducing the possibility of external rainwater entering the receiving groove, so that the staff can have sufficient time to open the cabinet door and the rain shield, and when the observation door is opened, the rain shield blocks the rainwater above, so that the staff can have sufficient time to open the observation door, so that the staff can reduce the entry of external rainwater during the maintenance process.

[0019] Optionally, a gear bar is provided on the rain shield, a rotating gear is rotatably connected to the cabinet, the gear bar and the rotating gear are meshed with each other, the rotating gear and the locking bar are meshed with each other, and when the rain shield moves out of the accommodating groove, the locking bar can disengage from the locking groove.

[0020] By adopting the above technical solution, the gear bar and the rotating gear are meshed with each other, and the rotating gear and the locking bar are meshed with each other. When the rain shield moves toward the outside of the accommodating groove, the rain shield drives the rotating gear to rotate through the gear bar, and the rotating gear can drive the locking bar to move, so that the locking bar moves away from the locking groove until the locking bar is disengaged from the locking groove, so that the staff can rotate the observation door to facilitate people to unlock the observation door when pulling the rain shield, so that the staff does not need to unlock the observation door separately, thereby reducing the staff's operating steps.

[0021] Optionally, a first magnet is slidably connected to the observation door, and a second magnet is provided on the rain shield. When the observation door is opened, the first magnet attracts the second magnet.

[0022] By adopting the above technical solution, the first magnet absorbs the second magnet and moves the first magnet toward the second magnet, so that the first magnet blocks the space between the observation door and the rain shield, making it difficult for rainwater to wet the maintenance personnel from the space between the observation door and the rain shield; at the same time, the first magnet absorbs the second magnet, so that the observation door can be fixed on the rain shield, making it difficult for the observation door to rotate after opening, so that the observation door can stably block the rain.

[0023] Optionally, a drainage groove is provided on the surface of the rain shield away from the accommodating groove. When the cabinet door is opened and the rain shield is pulled out, the distance between the drainage groove and the accommodating groove gradually decreases along the direction from the cabinet door to the rain shield, and the drainage groove extends to the side of the rain shield away from the cabinet door.

[0024] By adopting the above technical solution, the distance between the drainage groove and the receiving groove is gradually reduced in the direction from opening the cabinet door to pulling out the rain shield, and the drainage groove is extended to the side of the rain shield away from the cabinet door, so that rainwater can flow along the drainage groove to the other side, reducing the accumulation of rainwater above the rain shield, so that the staff will not easily get wet by the rainwater above when sliding the rain shield.

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

[0026] 1. The baffle plate extends along the circumference of the receiving groove to shield the cabinet door and the cabinet body, so that the wind and sand cannot be directly blown into the receiving groove from the gap between the cabinet door and the cabinet body, reducing the impact of the wind and sand entering the receiving groove on the electrical components, so that the distribution cabinet can operate normally in a windy and sandy climate; at the same time, when the cabinet door is impacted, the cabinet door abuts against the baffle plate, so that the baffle plate can provide certain support and buffering effects, reducing the risk of damage to the cabinet door.

[0027] 2. An observation glass is provided on the observation door, and the observation door is located on the side of the cabinet door facing the bottom wall of the receiving groove, so that the staff does not need to touch the electrical components during daily inspections. They only need to open the cabinet door and observe the interior through the observation glass. The obstruction of the observation door reduces the damage that the staff may suffer from accidentally touching the electrical components, thereby improving the safety performance of the distribution cabinet; the locking bar is inserted into the locking groove, and the groove wall of the locking groove limits the locking bar, so that the observation door can be fixed on the cabinet body, reducing the situation of accidental unlocking of the observation door and increasing the reliability of the observation door; at the same time, the staff first opens the cabinet door, then pulls the rain shield, and finally turns the observation door. The observation glass is provided on the observation door. When the cabinet door and the rain shield are opened, the observation door can block the receiving groove, reducing the possibility of external rainwater entering the receiving groove, so that the staff can have sufficient time to open the cabinet door and the rain shield, and when the observation door is opened, the rain shield blocks the rainwater above, so that the staff can have sufficient time to open the observation door, so that the staff can reduce the entry of external rainwater during the maintenance process.

The cabinet door 2 is integrally formed with a baffle 21 on its surface facing the cabinet body 1, and a baffle 22 is integrally formed on its surface away from the cabinet door 2, which extends along the circumference of the cabinet door 2. When the cabinet door 2 blocks the receiving groove 11, the baffle 22 abuts against the baffle 12.

[0041] The implementation principle of the embodiment 1 is: the cabinet door 2 is used to block the receiving groove 11 , and the blocking block 22 is allowed to abut against the baffle 12 , thereby reducing the possibility of wind and sand entering the receiving groove 11 .

[0042] Example 2

[0043] Reference Figure 3 The difference between this embodiment and embodiment 1 is that a receiving groove 31 is provided on the cabinet body 1, the cabinet door 2 can completely block the opening of the receiving groove 31, and the receiving groove 31 is located above the receiving groove 11. The upper side in this embodiment refers to the side of the receiving groove 11 away from the ground.

[0044] Reference Figure 3 and Figure 4A plurality of movable springs 311 are fixedly connected to the bottom wall of the receiving groove 31, and the plurality of movable springs 311 are arranged in an array along the length direction of the bottom wall of the receiving groove 31. A rain shield 3 is arranged in the receiving groove 31, and one end of the rain shield 3 is fixedly connected to the plurality of movable springs 311.

[0045] Reference Figure 3 and Figure 4 , the moving spring 311 drives the rain shield 3 to move to the accommodating groove 31, that is, when the rain shield 3 protrudes from the accommodating groove 31, the moving spring 311 is in a stretched state; when the rain shield 3 is completely located in the accommodating groove 31, the moving spring 311 is in a non-stressed state.

[0046] Reference Figure 4 and Figure 5 A limiting groove 32 is provided on the side of the rain shield 3, and a limiting spring 321 is fixedly connected to the bottom wall of the limiting groove 32. A limiting block 322 is fixedly connected to the surface of the limiting spring 321 away from the bottom wall of the limiting groove 32, and the limiting spring 321 drives the limiting block 322 to protrude from the limiting groove 32. When the limiting block 322 protrudes from the limiting groove 32, the limiting spring 321 is in a non-stressed state; when the limiting block 322 is located in the limiting groove 32, the limiting spring 321 is in a compressed state.

[0047] Reference Figure 4 and Figure 5 When the cabinet door 2 is in a closed state, a support block 232 is fixedly connected to the surface of the cabinet door 2 facing the cabinet body 1, and a through hole 23 is provided on the end surface of the support block 232 away from the cabinet door 2. The through hole 23 penetrates the surface of the cabinet door 2, and the through hole 23 is for the limit block 322 to be inserted. An operation bar 231 is slidably connected to the through hole 23, and the operation bar 231 can be completely located in the through hole 23. When the operation bar 231 is completely inserted into the through hole 23, the operation bar 231 abuts against the limit block 322, so that the limit block 322 is separated from the through hole 23. At this time, the rain shield 3 is subjected to the force of the moving spring 311, so that the rain shield 3 moves into the receiving groove 31.

When the limit block 322 is inserted into the through hole 23, the rain shield block 361 is located in the gap between the blocking bar 21 and the rain shield plate 3, so that the rain shield block 361 blocks the rain. The gap between the rain shield block 361 and the cabinet door 2 is the length of the blocking bar 21, and the rain here is not easy to enter due to the limit of the blocking bar 21.

[0049] Reference Figure 3 and Figure 6The cabinet body 1 is rotatably connected with an observation door 4, which is located on the side of the cabinet door 2 facing the bottom wall of the receiving groove 11. The observation door 4 is provided with a plurality of observation holes 41, and an observation glass 411 is fixedly connected to the observation hole 41, so that the staff can directly see the status of the electrical components through the observation glass 411.

[0050] Reference Figure 7 A gear bar 33 is fixedly connected to the rain shield 3, and the gear bar 33 extends along the length direction of the rain shield 3. A rotating hole 13 is provided on the cabinet 1, and the rotating hole 13 connects the receiving groove 11 and the receiving groove 31. A rotating gear 131 is rotatably connected in the rotating hole 13, and the rotating gear 131 is meshed with the gear bar 33. A locking bar 132 is slidably connected in the receiving groove 11, and the locking bar 132 and the rotating gear 131 are meshed with each other. A locking groove 42 for inserting the locking bar 132 is provided on the surface of the observation door 4 facing the bottom wall of the receiving groove 11. When the locking bar 132 is inserted into the locking groove 42, the observation door 4 completely blocks the opening of the receiving groove 11, and at this time the rain shield 3 is completely located in the receiving groove 31.

[0051] Reference Figure 7 When the rain shield 3 is pulled out of the accommodating groove 31, the rain shield 3 drives the rotating gear 131 to rotate through the gear bar 33, and the rotating gear 131 drives the locking bar 132 to move, so that the locking bar 132 is separated from the locking groove 42, thereby unlocking the observation door 4.

[0052] Reference Figure 8 A groove 43 is provided on the surface of the observation door 4, and the groove 43 extends along the width direction of the observation door 4. When the observation door 4 is closed, a through hole 431 connected to the groove 43 is provided on the surface of the observation door 4 away from the bottom wall of the accommodating groove 11. A first magnet 432 is slidably connected in the groove 43, and the first magnet 432 can block the gap between the rain shield 3 and the observation door 4. A convex strip 433 is fixedly connected to the first magnet 432, and the convex strip 433 can drive the first magnet 432 to move in the groove 43. A magnetic suction groove 34 is provided on the surface of the rain shield 3, and a second magnet 341 is fixedly connected in the magnetic suction groove 34, and the second magnet 341 can absorb the first magnet 432.

[0053] Reference Figure 8 When the rain shield 3 is pulled out and the observation door 4 is opened, the first magnet 432 attracts the second magnet 341 to fix the observation door 4 and the rain shield 3 to each other.

[0054] Reference Figure 3 and Figure 8A drainage groove 35 is provided on the surface above the rain shield 3. When the cabinet door 2 is opened, the rain shield 3 is pulled out, and the observation door 4 is opened, the drainage groove 35 penetrates to the side of the rain shield 3 away from the cabinet door 2, and the distance between the drainage groove 35 and the receiving groove 11 gradually decreases along the direction from the cabinet door 2 to the observation door 4, allowing rainwater to flow along the drainage groove 35 to the side of the observation door 4 away from the cabinet door 2. When rainwater flows from the drainage groove 35 to the observation door 4, the first magnet 432 attracts the second magnet 341, allowing the first magnet 432 to block the space between the observation door 4 and the rain shield 3, reducing the possibility of rainwater entering.

[0055] Reference Figure 3 When the cabinet door 2 is opened, the observation door 4 blocks the receiving groove 11, making it difficult for rainwater to enter the receiving groove 11, allowing the staff enough time to pull the rain shield 3. Since the rain shield 3 blocks the rainwater above the receiving groove 11, the staff has enough time to open the observation door 4.

[0056] The implementation principle of Example 2 is as follows: people first open the cabinet door 2, and then pull the rain shield 3 until the limit spring 321 drives the limit block 322 to insert into the through hole 23. At this time, the rain shield 3 is fixed on the cabinet door 2. At the same time, the rain shield 3 drives the rotating gear 131 to rotate through the gear bar 33, so that the rotating gear 131 drives the locking bar 132 to disengage from the locking groove 42, so that the staff can open the observation door 4 until the first magnet 432 attracts the second magnet 341. At this time, the observation door 4 and the rain shield 3 are fixed to each other.
