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] Distribution boxes are crucial equipment in electrical engineering, widely used in power distribution systems in various locations such as industrial plants, commercial buildings, and residential communities. They house various electrical components, such as circuit breakers, contactors, and relays. These components generate heat during operation and are highly sensitive to ambient humidity. Humid environments not only degrade the insulation performance of these components but can also cause short circuits, leakage currents, and other safety hazards, severely impacting the stability and lifespan of the power distribution system. Therefore, dehumidification technology for distribution boxes has always been an important research direction in the field of electrical engineering.
[0003] In existing technologies, such as Chinese patent CN211655428U, a distribution box for electrical engineering is disclosed. This box includes a body, a door, and a mounting plate. One side of the body is rotatably connected to the door via a pivot. One side of the door is detachably connected to a handle via screws. The other side of the body is fixedly connected to the mounting plate via screws. The mounting plate is detachably connected to a vacuum suction cup plate via screws and to a hanging plate via screws. The top of the body is fixedly connected to a rain cover via screws. Wiring holes are provided on the surface of the body. This technical solution, through the cooperation of the body, door, mounting plate, and other structures, improves the heat dissipation and dehumidification effect of the distribution box to a certain extent. Furthermore, the design of the vacuum suction cup plate and hanging plate provides multiple installation methods, avoiding damage to the wall.
[0004] However, the existing technologies still have the following shortcomings: First, their dehumidification function mainly relies on passive ventilation and heat dissipation, lacking an active dehumidification mechanism, resulting in limited dehumidification effect in high humidity environments; second, they lack intelligent humidity monitoring and control systems, failing to automatically adjust the dehumidification working state according to actual humidity conditions, leading to low energy efficiency; third, they lack the function of regenerating dehumidification materials, requiring frequent replacement, increasing maintenance costs and workload; finally, the structural design of the dehumidification system is not optimized, and both dehumidification efficiency and speed need improvement. Therefore, it is necessary to develop a new type of electrical engineering distribution box to overcome the above-mentioned deficiencies of the existing technologies. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a distribution box for electrical engineering.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An electrical engineering distribution box includes a distribution box with a dehumidification component on the bottom surface inside. The dehumidification component includes a fan duct, a circulating fan fixed inside the fan duct, a connecting pipe at the top of the circulating fan, a condensation chamber at the top of the connecting pipe, a gas-liquid pipe at the bottom of the condensation chamber, and the bottom end of the gas-liquid pipe penetrating the back side wall of the distribution box. A fan hood is provided at the bottom of the fan duct, and a storage box is movably inserted inside the fan hood. The storage box contains silica gel desiccant, and a number of air holes are opened at both the top and bottom of the storage box. A linkage component for controlling its vibration is provided at the top of the storage box.
[0008] The above technical solution achieves a dual dehumidification function that combines physical adsorption and condensation dehumidification through the coordinated operation of components such as the air duct, circulating fan, condensation chamber, and storage box, significantly improving the dehumidification efficiency inside the distribution box.
[0009] Preferably, the linkage component includes a chassis located at the center of the top of the storage box, a plurality of hemispheres arranged in an equidistant circular array on the top of the chassis, a rotating rod vertically and coaxially located at the bottom of the circulating fan, a lever coaxially located at the bottom of the rotating rod, a ball head located at the bottom of the lever, and the bottom of the ball head slidingly abutting against the top of the hemisphere.
[0010] Through the above technical solution, the linkage component uses the mechanical transmission of the rotating rod, lever, ball head and hemisphere to make the storage box vibrate periodically, which effectively prevents the silica gel desiccant from clumping and maintains its optimal moisture absorption activity.
[0011] Preferably, each of the four corners of the bottom of the storage box is provided with a vertical sliding column, and a spring is slidably fitted on the outer circumference of each sliding column. The bottom of the sliding column is slidably fitted with the same base, and the base is fixed to the bottom surface inside the distribution box.
[0012] The above technical solution, consisting of a sliding column, spring, and base, provides an elastic support system that ensures the stability of the storage box during vibration and facilitates quick disassembly and assembly of the storage box and replacement of the desiccant.
[0013] Furthermore, heating elements are provided on the side walls of the storage box.
[0014] Through the above technical solutions, the heating element enables in-situ regeneration of silica gel desiccant, eliminating the need for frequent desiccant replacement and significantly reducing maintenance costs and workload.
[0015] Furthermore, the inner sidewalls of the condensation chamber are equipped with semiconductor condensation plates.
[0016] Through the above technical solutions, semiconductor condenser plates improve the efficiency and accuracy of condensation dehumidification, ensuring that the treated air reaches the ideal level of dryness.
[0017] Preferably, the distribution box has a number of ventilation windows on both sides.
[0018] Through the above technical solutions, the setting of heat dissipation windows improves the air exchange inside and outside the distribution box, which not only assists in heat dissipation but also promotes dehumidification circulation, thereby improving the overall system performance.
[0019] Preferably, the distribution box is also equipped with a central controller and a humidity sensor. The central controller is electrically connected to the circulating fan, the semiconductor condenser and the heating element. The central controller reads the humidity monitoring data from the humidity sensor and controls the operation of the circulating fan, the semiconductor condenser and the heating element.
[0020] Through the above technical solutions, the intelligent control system consisting of a central controller and a humidity sensor realizes the automated operation and on-demand operation of the dehumidification equipment, achieving energy-saving and environmentally friendly effects.
[0021] The beneficial effects of this utility model are as follows:
[0022] 1. This utility model employs a dual dehumidification technology combining physical adsorption of silica gel desiccant with condensation dehumidification of semiconductor condenser plates. Compared to traditional single dehumidification methods, it offers faster dehumidification speed and more thorough dehumidification. The periodic vibration generated by the linkage components keeps the silica gel desiccant in a loose state, preventing clumping and subsequent decrease in moisture absorption efficiency. This ensures the long-term stable and efficient operation of the dehumidification system and effectively protects electrical equipment in the distribution box from damage caused by a humid environment.
[0023] 2. By using heating elements to regenerate saturated silica gel desiccant in situ, the desiccant is recycled, avoiding the material and labor costs associated with frequent desiccant replacements. The intelligent control system automatically adjusts the start and stop of each component based on actual humidity levels, preventing energy waste caused by idling. Compared to traditional continuously operating dehumidification solutions, this method offers significant energy savings and reduces overall operating costs.
[0024] 3. The central controller, in conjunction with a humidity sensor, enables fully automated operation of the dehumidification system, eliminating the need for manual supervision and frequent inspections, significantly reducing maintenance workload. The storage box adopts a movable insertion structure, coupled with a flexible support system, making desiccant inspection and replacement simple and quick. The entire system operates stably and reliably with a low failure rate, improving the overall operational reliability and service life of the distribution box.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0033] Example 1
[0034] Reference Figures 1 to 5 This embodiment provides a distribution box for electrical engineering, including a distribution box 1. The distribution box 1 has several ventilation windows 2 on both sides to ensure air circulation inside the box. A dehumidification assembly 3 is installed on the bottom surface inside the distribution box 1 for dehumidifying the interior of the distribution box.
[0035] like Figure 2 and Figure 3 As shown, the dehumidification assembly 3 includes a fan duct 31, which is vertically fixed to the bottom surface inside the distribution box 1. A circulating fan 32 is fixedly installed inside the fan duct 31. A connecting pipe 34 is connected to the top of the circulating fan 32, extending upwards in a curved shape, and its top end communicates with the condensation chamber 35. The condensation chamber 35 is horizontally positioned, and semiconductor condenser plates 15 are installed on its inner sidewalls for cooling and condensing the incoming hot and humid air. A gas-liquid pipe 36 is connected to the bottom of the condensation chamber 35, extending downwards and penetrating the back sidewall of the distribution box 1 to discharge condensate.
[0036] A fan hood 33 is installed at the bottom of the air duct 31, and a storage box 4 is movably inserted inside the fan hood 33. The storage box 4 is a detachable structure and is filled with silica gel desiccant 5. A number of air holes 41 are evenly distributed at the top and bottom ends of the storage box 4 to ensure that air can pass smoothly through the silica gel desiccant 5 inside the storage box 4. Heating plates 6 are installed on the side walls of the storage box 4 for heating and regenerating the saturated silica gel desiccant 5.
[0037] like Figure 4 As shown, a linkage assembly is provided on the top of the storage box 4 to drive the storage box 4 to vibrate when the circulating fan 32 is working. The linkage assembly includes a chassis 13 fixed to the center of the top of the storage box 4, and a plurality of hemispheres 14 are equidistantly arranged in a circular array on the top of the chassis 13. A rotating rod 10 is vertically and coaxially arranged at the bottom of the circulating fan 32. The rotating rod 10 extends downward through the air duct 31, and a lever 11 is coaxially fixed at its bottom end. The lever 11 is horizontally arranged, and a ball head 12 is provided at its bottom. The bottom end of the ball head 12 slides and abuts against the top end of the hemisphere 14.
[0038] Each of the four bottom corners of the storage box 4 has a vertically mounted sliding post 8, and a spring 7 is slidably fitted onto the outer circumference of each sliding post 8. The bottoms of the four sliding posts 8 are slidably fitted onto the same base 9, which is fixedly installed on the inner bottom surface of the distribution box 1. This elastic support structure allows the storage box 4 to vibrate in the vertical direction.
[0039] The distribution box 1 is also equipped with a central controller and a humidity sensor. The central controller is electrically connected to the circulating fan 32, the semiconductor condenser 15, and the heating element 6. The humidity sensor monitors the humidity inside the distribution box 1 in real time. The central controller reads the humidity monitoring data from the humidity sensor and controls the operation of the circulating fan 32, the semiconductor condenser 15, and the heating element 6 according to the preset humidity threshold.
[0040] I have worked as follows:
[0041] When the humidity sensor detects that the humidity inside the distribution box 1 exceeds a preset threshold, the central controller initiates the dehumidification program. First, the circulating fan 32 starts operating, creating a negative pressure inside the air duct 31, causing humid air from the distribution box 1 to enter through the air vent 41 at the bottom of the storage box 4. As the air passes through the storage box 4, the moisture in it is absorbed by the silica gel desiccant 5, achieving initial dehumidification.
[0042] The air, after initial dehumidification, enters the air duct 31 through the vent 41 at the top of the storage box 4. Driven by the circulating fan 32, it then flows through the connecting pipe 34 into the condenser chamber 35. Simultaneously, the central controller activates the semiconductor condenser 15 to cool the air entering the condenser chamber 35. Remaining moisture in the air condenses into water droplets at the low temperature, which collect and are discharged outside the distribution box 1 through the gas-liquid pipe 36. The thoroughly dehumidified air then returns to the inside of the distribution box 1, completing one dehumidification cycle.
[0043] During the operation of the circulating fan 32, the rotating rod 10 drives the lever 11 to rotate, and the ball head 12 contacts each hemisphere 14 on the chassis 13 in sequence. Each contact generates a downward thrust, causing the storage box 4 to move downward against the elastic force of the spring 7; when the ball head 12 leaves the hemisphere 14, the storage box 4 returns to its original position under the action of the spring 7. This periodic up-and-down vibration prevents the silica gel desiccant 5 from clumping, keeps it in a loose state, and improves moisture absorption efficiency.
[0044] When the silica gel desiccant 5 is nearly saturated with water, the central controller activates the heating element 6 to regenerate it. During the heating process, the moisture adsorbed in the silica gel desiccant 5 is evaporated and condensed and discharged into the condensation chamber 35 with the circulating airflow, thereby restoring the moisture absorption capacity of the silica gel desiccant 5.
[0045] Under the intelligent control of the central controller, the entire dehumidification system operates automatically according to the actual humidity inside the distribution box 1, realizing the automated dehumidification function of the distribution box and effectively protecting the electrical equipment inside the box from the damage of the humid environment.
[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
