Description

Technical Field

[0001] This invention belongs to the field of distribution box technology, and specifically discloses a distribution box with an anti-accidental contact protection structure. Background Technology

[0002] With the deepening construction of smart grids and ubiquitous power Internet of Things, and the large-scale integration of distributed energy resources and electric vehicle charging facilities, the deployment density and functionality of distribution boxes, as key end nodes in power distribution and control, have significantly increased. At the same time, the operating environment of distribution boxes is becoming increasingly complex, with many installed in public areas, residential communities, and industrial and commercial sites, facing the potential risk of accidental contact by non-professionals. Currently, higher requirements are being placed on the physical safety and human-machine interaction safety of power distribution equipment, especially outdoor / indoor distribution boxes exposed to complex environments.

[0003] In existing electrical distribution boxes, the core safety design generally focuses on the external door locks and sealing performance. However, this open design has a significant structural flaw: the door locks can be opened by unauthorized personnel (such as curious members of the public, children, or unqualified individuals) due to negligence, key duplication, or mechanical damage. Once the door is open, the exposed live conductors inside pose a direct threat to life, easily leading to electrocution and other serious accidents. Simultaneously, all internal electrical components (such as circuit breakers, terminal blocks, and control modules) are completely exposed and in an open state without any additional protection. Therefore, to compensate for this flaw, some existing technologies have added fixed transparent baffles or mesh barriers inside the box. While these solutions isolate the view and direct contact to some extent, they introduce new problems. The rigid, fixed internal barriers severely encroach on the limited maintenance space inside the box, making wiring, debugging, and troubleshooting extremely inconvenient. Furthermore, their fixed structure cannot adapt to the dynamic adjustment needs of different component layouts, resulting in poor versatility.

[0004] In summary, existing distribution boxes need to be improved. They must meet the following conditions: First, they should have space adaptability, allowing them to be completely retracted into the enclosure without any visible presence when not under protection, thus isolating the box. Second, they should have a mechanical self-locking function, with an opening and closing logic that is transparent and convenient for authorized maintenance personnel, but poses a technical barrier that is difficult for non-professionals to understand and operate. Third, they should have independent protective capabilities, functioning as a physical isolation barrier even in extreme cases where the outer door completely fails. Fourth, they should be easy to install and remove. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the background art, and to propose a distribution box with an anti-accidental touch protection structure, including a box body and a door rotatably installed on one side of the front end of the box body. A buzzer alarm is provided on one side of the outer wall of the box body, and a controller is provided on the outer surface of the door. Horizontal bars are installed inside the box body, both vertically and near the front end. Vertical shells are fixedly installed at both ends of the two horizontal bars. The sides of the two vertical shells that are far apart from each other are connected to the inner wall of the box body. Both vertical shells are connected to a fixed rod through internally arranged telescopic members. The upper and lower ends of the two fixed rods are aligned with... The device is equipped with sliding shells. Both sets of sliding shells are connected to sliding pillars via internally provided elastic elements. Locking blocks are fixedly installed on the upper surfaces of both sliding pillars. Polygonal bolts are locked inside both locking blocks. Card blocks are fixedly installed on the outer surfaces of the two polygonal bolts on their adjacent sides. Elastic pleated sheets are fixedly locked inside both card blocks. Pull rods are fixedly installed on the outer edges of the two elastic pleated sheets on their adjacent sides. Locking elements for locking the pull rods are provided on the outer surface of the crossbar near the two pull rods. Thermal imaging infrared sensors are installed on the outer surfaces of the front ends of both pull rods.

[0006] In the above technical solution, the telescopic component further includes a sleeve and a locking rod. One end of the locking rod is connected to the inner wall of the box, and the other end of the locking rod is slidably sleeved inside the sleeve. The end of the sleeve away from the locking rod is connected to the outer wall of the fixed rod.

[0007] In the above technical solution, the elastic element further includes a tension spring and a positioning plate. The positioning plate is fixedly installed on the outer wall of one side of the sliding shell and close to the top. One end of the tension spring is connected to the outer surface of the positioning plate, and the end of the tension spring away from the positioning plate is connected to the outside of the sliding column.

[0008] In the above technical solution, the locking component further includes an electric push rod and a fixing plate. The electric push rod is fixedly connected to the housing. A locking hole is provided inside the fixing plate near the telescopic end of the electric push rod. The telescopic end of the electric push rod slides in the locking hole. A sliding component is provided at the bottom of the fixing plate.

[0009] In the above technical solution, the sliding component further includes a sliding rod, one end of which is fixedly installed on the outer surface of the crossbar, and a locking rod is slidably installed on the outside of the sliding rod. The upper end of the locking rod is connected to the bottom end of the fixed plate, and the two pull rods are provided with locking holes corresponding to the locking rod.

[0010] In the above technical solution, a cooling fan is further embedded in the bottom of the inner side of the box, and the air outlet of the cooling fan faces the inside of the box. Frame rods are fixedly installed on both sides of the inner wall of the box.

[0011] In the above technical solution, further, both of the two frame rods are slidably installed with sliding sleeves, and a rectangular tube is installed on the outer surface of the two sets of sliding sleeves on the side that is close to each other. The inner and outer sides of the rectangular tube are respectively connected and installed with liquid inlet pipe and liquid outlet pipe. A sliding groove is opened on one side of the outer wall of the box corresponding to the liquid inlet pipe and the liquid outlet pipe. An installation seat is fixedly installed at the bottom corner of the box.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention achieves optimal storage in the unprotected state by setting up a flexible protective barrier (elastic pleats) that can be intelligently triggered and adaptively deployed, reducing the usable maintenance space inside the enclosure. When the enclosure door is detected to be open, it can detect the approach of personnel and generate an alarm upon contact with the elastic pleats. Furthermore, the design of the elastic pleats forms a reliable physical isolation between electrical components and the operator, effectively preventing accidental contact with live parts, and resolving the contradiction between the space-consuming and inconvenient protection of existing fixed barriers.

[0013] 2. This invention constructs an intelligent protective opening and closing logic through the linkage design of a thermal imaging infrared sensor and an electric locking mechanism. This logic is transparent to maintenance personnel (through the control of the controller, during maintenance, the locking component disengages from the pull rod, and the elastic pleated plates retract to both ends), but for non-professionals without relevant knowledge or tools, it constitutes a technical barrier that is difficult to understand and operate. Thus, while ensuring the convenience of authorized operations, it significantly increases the difficulty and security of operation after unauthorized opening.

[0014] 3. The invention provides a convenient way to replace and disassemble the elastic pleats later by setting the locking block and elastic element, which greatly improves maintenance efficiency and has strong versatility.

[0015] 4. By using square tubes and cooling fans, the present invention partially seals off the airflow inside the box when facing the obstruction of elastic pleats. While achieving reliable protection, it can effectively ensure the heat dissipation effect inside the distribution box, avoid excessively high temperature inside the box due to the setting of the protective structure, ensure that electrical components are always in a suitable working environment, and extend the service life of the equipment.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-10The distribution box shown includes a protection structure against accidental contact, comprising a box body 1 and a door 3 rotatably mounted on the front side of the box body 1. A buzzer alarm 4 is installed on one side of the outer wall of the box body 1, and a controller 31 is installed on the outer surface of the door 3. Horizontal bars 7 are installed inside the box body 1, both vertically and near the front end. Vertical shells 8 are fixedly installed at both ends of the two horizontal bars 7. The sides of the two vertical shells 8 that are far apart from each other are connected to the inner wall of the box body 1. Both vertical shells 8 are connected to a fixed rod 32 via internal telescopic components. Sliding shells 13 are symmetrically installed at the upper and lower ends of the two fixed rods 32. Both sets of sliding shells 13 are connected by... The internal elastic element is connected to the sliding column 29. The upper end face of the two sliding columns 29 is fixedly installed with locking blocks 27. The two locking blocks 27 are fitted with polygonal bolts 19. The outer surface of the two polygonal bolts 19 that are close to each other is fixedly installed with a locking block 20. The two locking blocks 20 are fixedly fitted with elastic pleated pieces 16. The outer edge of the two elastic pleated pieces 16 that are close to each other is fixedly installed with a pull rod 18. The outer surface of the crossbar 7 and near the two pull rods 18 are provided with locking elements for locking the pull rods 18. The outer surface of the front end of the two pull rods 18 is equipped with a thermal imaging infrared sensor 9. In this example, the entire mechanism is based on two horizontal bars 7 built into the front end of the housing 1 and vertical shells 8 at both ends. The upper and lower fixed rods 32 are connected to the vertical shells 8 via telescopic components, providing a certain degree of front-to-back adjustment. The sliding shell 13, sliding column 29, and elastic element constitute the driving and resetting mechanism of the physical protective barrier. The two sides of the elastic pleated sheet 16 are fixed to the upper and lower sliding columns 29 via locking blocks 20, polygonal bolts 19, and locking blocks 27. The pull rod 18 is fixed to the inner edge of the pleated sheet, and its locking hole 26 engages with the locking element to achieve locking. In the protective state, the locking mechanism locks the two pull rods 18, and the elastic pleated sheet 16 is stretched out laterally to cover the front of the equipment inside the box; Under normal maintenance conditions, the operator can release the locking mechanism from the pull rod 18 by operating the controller 31. The restoring force of the elastic element is transmitted through the slide column 29, etc., which pulls the two sides of the elastic pleated sheet 16 to fold towards the inner wall of the box 1, making room for operation. In alarm mode, the thermal imaging infrared sensor 9 continues to operate after the door 3 is opened. When it detects unauthorized personnel touching the unfolded barrier, it can trigger the buzzer alarm 4 to sound an alarm, thus providing an early warning function.

[0021] The telescopic component includes a sleeve 21 and a locking rod 22. One end of the locking rod 22 is connected to the inner wall of the housing 1, and the other end of the locking rod 22 is slidably sleeved inside the sleeve 21. The end of the sleeve 21 away from the locking rod 22 is connected to the outer wall of the fixed rod 32. In this embodiment, the telescopic component consisting of the sleeve 21 and the locking rod 22 can maintain the normal elasticity of the elastic pleated sheet 16, and at the same time, the distance can be adjusted as needed.

[0022] The elastic element includes a tension spring 28 and a positioning plate 30. The positioning plate 30 is fixedly installed on the outer wall of one side of the sliding shell 13 and close to the top. One end of the tension spring 28 is connected to the outer surface of the positioning plate 30, and the other end of the tension spring 28 away from the positioning plate 30 is connected to the outside of the sliding column 29. In this embodiment, the elastic element with tension spring 28 as its core functions to provide a continuous and stable driving force for the elastic pleated sheet 16 to automatically return from the unfolded protective state to the retracted maintenance state. The positioning plate 30 fixes one end of the tension spring 28 and determines its force direction. This design ensures that after the locking is released, the barrier can quickly and reliably retract automatically without manual intervention, greatly improving maintenance efficiency. During operation, with the barrier deployed and locked, one end of the tension spring 28 is fixed to the positioning plate 30, and the other end is connected to the slide column 29. At this time, the tension spring 28 is in a stretched and energy-stored state. When the locking device releases the lock on the pull rod 18, the elastic restoring force of the tension spring 28 is immediately released, pulling the slide column 29 to slide inward towards the inside of the housing 1 within the sliding shell 13. The movement of the slide column 29 is transmitted to the edge of the elastic pleated sheet 16 through the locking block 27, the polygonal bolt 19, and the locking block 20, thereby quickly pulling it back and folding it up.

[0023] The locking mechanism includes an electric push rod 17 and a fixed plate 23. The electric push rod 17 is fixedly connected to the housing 1. A locking hole is provided inside the fixed plate 23 near the telescopic end of the electric push rod 17. The telescopic end of the electric push rod 17 slides in the locking hole. A sliding component is provided at the bottom of the fixed plate 23. The sliding component includes a slide rod 25. One end of the slide rod 25 is fixedly installed on the outer surface of the crossbar 7. A locking rod 24 is slidably installed on the outside of the slide rod 25. The upper end of the locking rod 24 is connected to the bottom end of the fixed plate 23. Locking holes 26 are provided on the two pull rods 18 corresponding to the locking rod 24. In this embodiment, the electric push rod 17 serves as a drive locking component, and the fixed plate 23 serves as a force transmission and connection component, together forming a controllable mechanical locking and unlocking actuator. Its function is to automatically lock and unlock the pull rod 18. During operation, the electric push rod 17 is fixed to the housing 1, and the movement of its telescopic end directly drives the mating fixing plate 23 to lock the locking rod 24. When it is necessary to lock the barrier, the locking rod 24 is inserted into the locking hole 26 of the pull rod 18, and then the electric push rod 17 is driven to extend and engage with the locking hole inside the fixing plate 23 to achieve mechanical locking. During maintenance, the electric push rod 17 retracts, disengages from the fixing plate 23, and the locking rod 24 is pulled out to disengage from the locking hole 26, thus releasing the lock.

[0024] A cooling fan 10 is embedded in the bottom of the inner side of the box 1, and the air outlet of the cooling fan 10 faces the inside of the box 1. A support rod 12 is fixedly installed on both sides of the inner wall of the box 1. A sliding sleeve 14 is slidably installed on the outside of the two support rods 12. A rectangular tube 11 is installed on the outer surface of the two sets of sliding sleeves 14 that are close to each other. An inlet pipe 6 and a drain pipe 15 are respectively connected and installed inside the rectangular tube 11. A groove 5 is opened on one side of the outer wall of the box 1, corresponding to the inlet pipe 6 and the drain pipe 15. A mounting base 2 is fixedly installed at the bottom corner of the box 1. In this embodiment, when the unfolded protective pleats 16 may affect the natural convection inside the enclosure, the cooling fan 10 embedded in the bottom of the enclosure 1 provides forced convection cooling. Its function is to actively draw in external cold air or agitate the air inside the enclosure, accelerating heat dissipation from the surface of electrical components and expelling it through the gaps in the enclosure 1. This effectively compensates for the potential decrease in heat dissipation efficiency due to the protective structure, ensuring the stable operating temperature of the electrical components. The support pole 12 provides a mounting base for a more efficient heat dissipation module in the future. After the cooling medium enters the rectangular tube 11 through the inlet pipe 6, it flows through the entire pipe and carries the absorbed heat out through the drain pipe 15, forming a circulation. The rectangular tube 11 is fitted onto two support rods 12 by sliding sleeves 14 at both ends. The operator can slide the entire rectangular tube 11 assembly along the axis of the support rods 12 to position it near the electrical components that require the most heat dissipation. The sliding grooves 5 on the side wall of the housing 1 provide the necessary movement space for the inlet pipe 6 and the drain pipe 15, ensuring that the pipes are not squeezed or bent when the position of the rectangular tube 11 is adjusted. At this time, the cooling fan 10 is started to generate airflow. As an air supply structure, cooler external air can be blown into the interior of the housing 1, directly blowing onto the rectangular tube 11, and then the cool air washes over the surface of the electrical components, timely uniformizing and carrying away the heat from local hot spots, preventing heat accumulation and excessive temperature rise.

[0025] It should be noted that the elastic pleat 16 is preferably made of flame-retardant thermoplastic polyurethane elastomer material, which is different from the elastic tension of the tension spring 28. The tension spring 28 serves as the main driving force for tension, and the locking structure of the polygonal bolt 19 ensures the tension of the elastic pleat 16 while facilitating disassembly. The elasticity of the elastic pleat 16 itself is used as its own elasticity according to the needs of the pleats.

[0026] Working principle: When the outer door 3 is opened due to negligence, the protective structure is designed independently of the door 3, and the elastic pleated plate 16 is in a locked and unfolded state. Non-staff members cannot know the opening and closing logic of the locking mechanism and cannot unlock the locking rod 24 through normal operation. The elastic pleated plate 16, together with the polygonal bolt 19, the locking block 20, and the fixed rod 32, can effectively prevent non-professionals from contacting live parts inside the box, forming a safety barrier and minimizing the risk of electric shock accidents. Only knowledgeable personnel can disarm the protection through the control panel 31, ensuring the independence and reliability of the protection.

[0027] During normal maintenance of the enclosure 1, the two elastic pleated panels 16 are locked near the front inner wall of the enclosure 1 by the locking mechanism via the pull rod 18 on their edges. At this time, the elastic pleated panels 16 are stretched. During maintenance, the operator can use the control panel 31 of the enclosure door 3 to disengage the telescopic end of the electric push rod 17 from the locking hole of the fixing plate 23. Then, the operator moves the fixing plate 23 to slide the locking rod 24 along the outside of the slide rod 25, causing the locking rod 24 to disengage from the locking hole 26 and release the lock on the pull rod 18. Subsequently, the tension spring 28 releases its elastic potential energy, pulling the slide column 29 to slide horizontally within the sliding housing 13. The slide column 29, through the locking block 27, drives the polygonal bolt 19 and the locking block 20 to move synchronously, thereby pulling the elastic pleated panels 16 to retract towards the inner wall of the enclosure 1.

[0028] In special circumstances, if a non-staff member touches the elastic pleated sheet 16 after the door 3 is opened, the thermal imaging infrared sensor 9 installed at the front end of the lever 18 will continuously scan the protected area and accurately capture human infrared signals. This sensor is connected to the control panel 31 in real time and will only trigger a response to human signals attempting to touch the elastic pleated sheet 16. At this time, the buzzer alarm 4 will sound an alarm to warn the surrounding area.

[0029] With the flexible pleated fins 16 in place, the cooling fan 10 at the bottom inner side of the enclosure 1 runs continuously, with the air outlet facing inwards to accelerate air circulation and remove the heat generated by the electrical components. Simultaneously, the rectangular tube 11 is connected to the cooling medium via the liquid inlet pipe 6. The cooling medium circulates within the rectangular tube 11, absorbing heat from localized high-heat areas within the enclosure before being discharged through the drain pipe 15, achieving dual cooling through both air and liquid. The rectangular tube 11 slides against the support rod 12 via a sliding sleeve 14, allowing the distance between the rectangular tube 11 and the electrical components to be adjusted along the outside of the support rod 12 according to the position of the heat-generating components inside the enclosure, ensuring targeted heat dissipation. The sliding groove 5 on the outer wall of the enclosure 1 provides space for the liquid inlet pipe 6 and the drain pipe 15, preventing the pipes from twisting or breaking due to the movement of the rectangular tube 11. In summary, under normal maintenance conditions, the use of the elastic pleated sheet 16 can be controlled by the locking mechanism without touching it. Under abnormal maintenance conditions, the elastic pleated sheet 16 is located at the front end of the housing 1, forming an erect barrier in an unfolded state. An alarm is triggered upon contact with it to prevent accidental contact by unauthorized personnel from causing danger.
