Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a distribution box for electrical engineering. Background Technology

[0002] Electrical engineering is one of the core and key disciplines in modern science and technology. Traditionally, electrical engineering is defined as the sum of disciplines related to the creation of electrical and electronic systems. However, with the rapid development of science and technology, the concept of electrical engineering has far exceeded this definition, encompassing almost all engineering activities related to electronics and photonics. It is precisely the tremendous progress in electronic technology that has driven the arrival of the information age based on computer networks, and has changed all aspects of human life and work.

[0003] Electrical engineering not only focuses on the production, transmission, distribution, and use of electrical energy, but also involves the safe, reliable, and economical operation of power systems, as well as the engineering technologies related to the design, manufacture, operation, measurement, and control of various electrical equipment and systems. It is closely linked to engineering fields such as electronic and communication engineering, computer technology, control engineering, materials engineering, mechanical engineering, instrumentation engineering, and power engineering.

[0004] A distribution box is a device used in electrical engineering for the distribution, control, and protection of electrical energy. It is assembled in a closed or semi-closed metal cabinet, housing switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment. The main functions of a distribution box include the rational distribution of electrical energy, effective circuit control, fault protection, and power consumption management. It is widely used in construction, industry, agriculture, and transportation, and is an important component in ensuring the safe and reliable operation of power systems.

[0005] In the actual operation of some electrical engineering distribution boxes, defects or a lack of effective cleaning and maintenance mechanisms make it difficult to effectively clean the dust on the filter plates. Some distribution boxes simply install the filter plates at the ventilation openings without corresponding automatic cleaning devices or convenient manual cleaning mechanisms. When the distribution box is in a harsh working environment for a long time, such as a dusty place with many fibrous materials, dust will quickly accumulate on the surface of the filter plate, gradually clogging the mesh. As the dust layer thickens, the resistance to airflow through the filter plate increases significantly, significantly reducing the efficiency of the fan in drawing outside air into the box. This prevents effective air convection to remove the heat generated by the electrical equipment inside the distribution box. This not only causes the internal temperature of the distribution box to rise continuously, exceeding the allowable temperature range for normal operation of the electrical equipment, affecting the performance and stability of the equipment, but also leads to electrical faults due to overheating, and even serious safety accidents such as equipment damage, short circuits, and fires, posing a great threat to the safe and reliable operation of the entire electrical engineering system. Therefore, to address these shortcomings, a new type of electrical engineering distribution box is proposed to solve these problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a distribution box for electrical engineering, which aims to improve the problem that the filter plates of some existing electrical engineering distribution boxes cannot be effectively cleaned to ensure heat dissipation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An electrical engineering distribution box includes a box body, with heat dissipation mechanisms on both the left and right sides of the box body, two rotating doors rotatably connected to the front of the box body, a mounting plate fixedly connected to the inside of the box body, multiple power distribution units mounted on the front of the mounting plate, a wire bundling mechanism for bundling wires provided on the front of the mounting plate, and handles fixedly connected to the front of the two rotating doors.

[0009] The heat dissipation mechanism includes two fixed frames, with their adjacent sides fixedly connected to the left and right sides of the housing, respectively. Two fixed rods are fixedly connected inside each of the two fixed frames, and springs are fitted around the outside of each of the fixed rods. Sliding plates are slidably connected inside each of the two fixed frames. Two fans are fixedly connected inside the housing, with filter plates fixedly connected to the opposite sides of each of the two fans. Scrapers are fixedly connected to the rear sides of each of the two sliding plates, and connecting ropes are fixedly connected to the front sides of each of the two fixed frames. Fixed rings are fixedly connected to the front sides of the housing. Guide wheels are fixedly connected to the outside of the housing. Fixed discs are fixedly connected to the front sides of each of the two rotating doors. Multiple heat dissipation holes are provided inside the housing.

[0010] As a further description of the above technical solution:

[0011] The wire harnessing mechanism includes a mounting plate with multiple wire placement plates fixedly connected to the front side, a wire clamping plate rotatably connected to the front side of each of the multiple wire placement plates, a wire harnessing groove I opened inside each of the multiple wire placement plates, a wire harnessing groove II opened at the bottom of each of the multiple wire clamping plates, two clamping plates fixedly connected to the bottom of each of the multiple clamping plates, multiple clamping holes opened inside each of the multiple clamping plates, two handles fixedly connected to the front side of each of the multiple wire clamping plates, a clamping groove opened on the bottom side of the interior of each of the multiple wire placement plates, and multiple clamping balls fixedly connected inside the interior of each of the multiple wire placement plates.

[0012] As a further description of the above technical solution:

[0013] One end of the spring is fixedly connected to the rear side of the sliding plate, and the other end of the spring is fixedly connected to the inside of the fixed frame;

[0014] As a further description of the above technical solution:

[0015] The sliding plate is slidably connected to the outside of the fixed rod, and the scraper is slidably connected to the side of the filter plate away from the fan.

[0016] As a further description of the above technical solution:

[0017] One end of the connecting rope is fixedly connected to the side of the sliding plate away from the scraper, and the other end of the connecting rope is fixedly connected to the outside of the fixed disc.

[0018] As a further description of the above technical solution:

[0019] The outer side of the connecting rope is slidably connected to the outside of the guide wheel, and the outer side of the connecting rope is slidably connected to the inside of the fixing ring;

[0020] As a further description of the above technical solution:

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, when the rotating door opens or closes, the connecting rope slides on the fixed ring and guide wheel, causing the sliding plate to move back and forth on the fixed rod. The scraper connected to the sliding plate then slides on the surface of the filter plate. The filter plate effectively blocks external dust from entering the box, and the regular cleaning action of the scraper prevents dust from accumulating on the filter plate. This ensures that the fan can continuously and efficiently draw in cool outside air into the box and extract hot internal air. The fans on both sides create good air convection, maintaining a stable and suitable temperature environment inside the box. This ensures normal heat dissipation of the electrical equipment inside the distribution box, greatly improving the heat dissipation performance and reliability of the distribution box and extending the service life of the electrical equipment.

[0026] 2. In this utility model, after the power distribution unit is installed, its cables are placed in the cable tray of the cable holder plate. Then, by rotating the clamping plate with the handle, the cable tray at the bottom of the clamping plate, together with the cable tray, forms a cable clamping channel, limiting and fixing the cables. Simultaneously, the retaining plate at the bottom of the clamping plate slides into the retaining plate's slot for horizontal positioning, and the retaining ball slides into the retaining hole to further fix the retaining plate and the clamping plate. This design allows the cables to be neatly and securely organized and fixed, avoiding a messy distribution. This not only makes the internal space of the distribution box more organized and facilitating later maintenance, repair, and troubleshooting, but also reduces electrical safety hazards caused by messy cables, such as cable wear and short circuits, improving the overall safety and stability of the distribution box.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figures 1 to 3 This utility model provides an embodiment of an electrical engineering distribution box, including a box body 1. The box body 1 serves as the main structure of the entire distribution box, providing an installation foundation and protective space for other components. Heat dissipation mechanisms are provided on both the left and right sides of the box body 1. Two rotating doors 13 are rotatably connected to the front of the box body 1. A mounting plate 14 is fixedly connected inside the box body 1. Multiple power distribution units 16 are mounted on the front of the mounting plate 14. A wire-binding mechanism for wire bundling is provided on the front of the mounting plate 14. Handles 26 are fixedly connected to the front of each of the two rotating doors 13.

[0039] Reference Figures 2 to 4The heat dissipation mechanism includes two fixed frames 2, with their adjacent sides fixedly connected to the left and right sides of the housing 1, respectively. Two fixed rods 3 are fixedly connected inside each of the two fixed frames 2, providing guidance and support for the sliding plate 5. Springs 4 are fitted onto the outside of each of the fixed rods 3. One end of the spring 4 is fixedly connected to the rear side of the sliding plate 5, and the other end is fixedly connected to the inside of the fixed frame 2. When the sliding plate 5 is displaced by elastic force, the spring 4 is stretched, releasing its elastic potential energy. Once the external force disappears, the spring 4 pushes the sliding plate 5 back to its initial position using its own elastic restoring force. Sliding plates 5 are slidably connected inside each of the two fixed frames 2, and the outside of the sliding plates 5 is slidably connected to the outside of the fixed rods 3. Two fans 6 are fixedly connected inside the housing 1. The fans 6 are active heat dissipation components in the heat dissipation mechanism; they are driven by a motor to rotate the blades at high speed, generating a powerful airflow to ensure efficient extraction of hot air from inside the housing 1 and intake of cool air from the outside.

[0040] Reference Figures 2 to 4 Each of the two fans 6 has a filter plate 7 fixedly connected to its opposite side. The filter plates 7 are externally fixedly connected to the inside of the housing 1. Each of the two sliding plates 5 has a scraper 8 fixedly connected to its rear side. When the sliding plates 5 slide back and forth under the action of the spring 4 and the connecting rope 9, the scraper 8 will slide on the surface of the filter plate 7, scraping off the dust attached to the filter plate 7. When the connecting rope 9 is pulled by the opening and closing action of the rotating door 13, the sliding plate 5 will slide back and forth along the fixed rod 3. The scraper 8 is externally slidably connected to the filter plate 7 on the side away from the fan 6. Connecting ropes 9 are fixedly connected to the front of both sliding plates 5, with one end of the rope fixedly connected to the side of the sliding plate 5 away from the scraper 8 and the other end fixedly connected to the outside of the fixed plate 12. Fixed rings 10 are fixedly connected to the front of both fixed frames 2, with the connecting rope 9 externally slidably connected to the inside of the fixed rings 10. Guide wheels 11 are fixedly connected to the outside of the housing 1, with the connecting rope 9 externally slidably connected to the outside of the guide wheels 11. The guide wheels 11 change the direction of movement of the connecting rope 9. Fixed plates 12 are fixedly connected to the front of both rotating doors 13. When the rotating doors 13 open or close, the fixed plates 12 move with the rotating doors 13, thereby pulling or releasing the connecting rope 9. Multiple heat dissipation holes 15 are provided inside the housing 1.

[0041] Reference Figures 5 to 7The cable clamping mechanism includes a mounting plate 14 with multiple cable placement plates 17 fixedly connected to its front side. Each cable placement plate 17 has a clamping plate 18 rotatably connected to its front side. When the clamping plate 18 is closed, it forms a closed cable clamping space with the cable placement plates 17. The rear side of the clamping plate 18 is rotatably connected to the front side of the cable placement plates 17 via hinges. Each cable placement plate 17 has a cable clamping groove 19 inside, the shape and size of which match the diameter of the cable, allowing the cable to be neatly placed within it and providing a certain degree of positioning and fixing. Each clamping plate 18 has a cable clamping groove 20 at its bottom, which together with the clamping groove 20 forms a cable clamping channel. Each clamping plate 18 has two locking plates 21 fixedly connected to its bottom, each locking plate 21 having multiple locking holes 22 inside. Each clamping plate 18 has two handles 23 fixedly connected to its front side.

[0042] Reference Figures 6 to 8 Each of the multiple cable-holding plates 17 has a slot 24 on its inner bottom side. A clamping plate 21 is slidably connected to the inside of the slot 24. When the cable-holding plate 18 rotates to close, the clamping plate 21 can slide into the slot 24, thereby achieving horizontal positioning and fixation of the cable-holding plate 18. Multiple retaining balls 25 are fixedly connected to the inside of each of the multiple cable-holding plates 17. The retaining balls 25 are slidably connected to the inside of the retaining holes 22. The function of the clamping plate 21 is to cooperate with the slots 24 and retaining balls 25 on the cable-holding plate 17 to fix the cable-holding plate 18 to the cable-holding plate 17.

[0043] Working principle: When using this distribution box, opening the rotating door 13 causes the connecting rope 9 to slide inside the fixing ring 10. At this time, the spring force of the spring 4 causes the sliding plate 5 and scraper 8 to slide outside the filter plate 7, thus cleaning the surface of the filter plate 7 every time the rotating door 13 is opened and closed, effectively preventing dust accumulation. Then, the fan 6 draws outside air into the box 1, and the air convection is formed by the two side fans 6, which effectively heats up the interior. After the power distributor 16 is installed, the cable of the power distributor 16 can be placed inside the cable tray 19. Then, the handle 23 can drive the clamping plate 18 to rotate, so that the clamping plate 18 and the cable placement plate 17 can fix and hold the cable. At the same time, the card plate 21 slides into the card slot 24, and the card ball 25 slides into the card hole 22 to fix the card plate 21 and the clamping plate 18, thus effectively organizing the cable.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
