This active heat dissipation method can effectively reduce the temperature inside the box, maintaining the environment within the box within a suitable temperature range, providing good conditions for the normal operation of electrical components, improving the heat dissipation efficiency and reliability of the distribution box, and ensuring the stability and safety of the equipment during long-term operation;

[0018] Fourth, during use, through the observation hole and glass, workers can intuitively and clearly observe the operating status of the metering units and other equipment inside the box frame without opening the front box door. This not only saves workers' operating time and improves work efficiency, but also avoids the adverse effects of dust and moisture introduced by frequent opening of the box door on the electrical components inside the box. At the same time, it reduces safety hazards caused by misoperation and provides a more convenient and safe method for the daily maintenance and management of the distribution box. This thermal insulation design enables the distribution box to maintain good operating status in different temperature environments, improves the adaptability and reliability of the equipment, and extends the service life of the equipment.

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-Figure 7 As shown, a waterproof low-voltage integrated distribution box with adjustable installation angle includes a top cover 1, which is fixed to the top surface of a box frame 2. Side panels 3 are fixed to the left and right sides of the box frame 2. The front side of the box frame 2 is connected to a front box door 4 by a hinge, and the rear side of the box frame 2 is connected to a rear box door 5 by a hinge. Two movable frames 6 are movably provided below the box frame 2, and U-shaped frames 7 are rotatably provided inside the two movable frames 6. The inner bottom surfaces of the two U-shaped frames 7 are respectively provided with a plurality of mounting holes 8. A rotating hole 9 is provided on the front and rear sides of each movable frame 6, and a rotating shaft 10 is fixed on the front and rear sides of the two U-shaped frames 7. The two rotating shafts 10 are rotatably arranged in the two rotating holes 9 respectively, and a turntable 11 is fixed on the outer ends of the two rotating shafts 10. A threaded groove 12 is provided on the front and rear sides of the two movable frames 6, and a plurality of first threaded holes 13 are provided on the outer sides of the two turntables 11. The internal thread of the threaded groove 12 is connected to a bolt 14, and the threaded end of the bolt 14 is threadedly connected to the first threaded hole 13.

[0029] In use, the top cover 1, the box frame 2, the two side panels 3, the front box door 4 and the rear box door 5 together constitute a distribution box body, which provides a reliable protection space for the internal electrical components. When the staff needs to install the distribution box, the mounting holes 8 on the two U-shaped frames 7 play a key role and become the connection points for fixing the distribution box to the mounting surface. In actual installation scenarios, since the mounting surface may have different degrees of inclination, traditional distribution boxes are difficult to adapt to such complex situations. The present distribution box has achieved the adjustability of the installation angle through a unique design. The staff only needs to unscrew the bolt 14 on the right side from the thread groove 12 and the first threaded hole 13. At this time, the U-shaped frame 7 can rotate freely inside the movable frame 6, and the rotating shaft 10 rotates smoothly in the rotating hole 9, thereby adjusting the angle of the U-shaped frame 7. After the angle is adjusted to the appropriate position, the threaded end of the bolt 14 is screwed into the corresponding first threaded hole 13 and thread groove 12 in turn to complete the firm fixation of the U-shaped frame 7. The angle adjustment method of the left U-shaped frame 7 is the same as that of the right.

[0030] Through the coordinated action of the top cover 1, the box frame 2, the side panel 3, the front box door 4, the rear box door 5, the movable frame 6, the U-shaped frame 7, the mounting hole 8, the rotating hole 9, the rotating shaft 10, the turntable 11, the threaded groove 12, the first threaded hole 13 and the bolt 14, the distribution box can flexibly adapt to the inclination requirements of different installation surfaces, thereby improving the versatility and convenience of installation, reducing the difficulty or inability to install due to installation surface problems, and providing strong guarantees for the installation of the distribution box in various complex environments.

[0031] like Figure 1-Figure 3 、 Figure 6 and Figure 7 As shown, a mounting frame 15 is fixed to the bottom surface of the box frame 2, and a movable groove 16 is provided on the bottom surface of the mounting frame 15. A motor 17 is fixed to the right side of the mounting frame 15. The output shaft of the motor 17 passes through the mounting frame 15 and is fixed with a bidirectional screw rod 18. Movable blocks 19 are respectively fixed to the top surfaces of the two movable frames 6. A second threaded hole 20 is respectively provided on one side of the two movable blocks 19. The two second threaded holes 20 are respectively threadedly connected to the threaded ends of the bidirectional screw rod 18.

[0032] During use, when faced with installation positions with different spacings or when the distance between the two U-shaped frames 7 needs to be adjusted according to actual needs, the staff only needs to start the motor 17, and the output shaft of the motor 17 drives the bidirectional screw rod 18 to rotate. Since the two movable blocks 19 are threadedly connected to the bidirectional screw rod 18 through the second threaded hole 20 respectively, under the rotation of the bidirectional screw rod 18, the two movable blocks 19 will move left and right regularly inside the movable groove 16. This movement enables the two movable blocks 19, the two movable frames 6 and the two U-shaped frames 7 to approach or move away from each other, thereby conveniently and quickly adjusting the distance between the two, enhancing the flexibility of the distribution box installation, and being able to meet the needs of various installation scenarios.

[0033] like Figures 1-4 、 Figure 6 and Figure 7 As shown, the front and rear sides of the inner wall of the movable groove 16 are respectively provided with slide grooves 21, the front and rear sides of the two movable blocks 19 are respectively fixed with sliders 22, and the two sliders 22 are slidably arranged in the two slide grooves 21, and a plurality of ventilation holes 23 are respectively provided on one side of the two side panels 3, and a plurality of drainage holes 24 are provided on the inner bottom surface of the box frame 2, and two water retaining plates 25 are respectively fixed on the inner sides of the two side panels 3.

[0034] During use, when the movable block 19 is moved left and right by the bidirectional screw rod 18, the slider 22 slides inside the slide groove 21, which can limit the movable block 19 and ensure that the movable block 19 does not deviate or shake during the left and right movement, thereby improving stability. The ventilation holes 23 and the drainage holes 24 together constitute the ventilation and drainage system of the distribution box, which plays an important role in ensuring the stability of the internal environment of the distribution box. The setting of the ventilation holes 23 is conducive to the circulation of air between the inside of the box frame 2 and the outside, achieving good ventilation and heat dissipation effects, and preventing the temperature inside the box from being too high and affecting the performance and service life of the electrical components. However, in adverse weather conditions such as rainy days, rainwater may enter the box frame 2 through the ventilation holes 23. At this time, the drainage holes 24 play a key role. The rainwater entering the box will fall on the inner bottom surface of the box frame 2 and then be smoothly discharged outside the box through the drainage holes 24, avoiding the accumulation of rainwater in the box, thereby effectively protecting the electrical components in the box from rainwater erosion, ensuring the normal operation of the distribution box in various weather conditions, and improving the waterproof performance and reliability of the distribution box. Although the ventilation holes 23 and the drainage holes 24 guarantee the ventilation and drainage needs of the distribution box to a certain extent, when the external rain is heavy or the wind is strong, some rainwater may still enter the box frame 2 through the ventilation holes 23. At this time, the water baffle 25 fixed on the inner side of the two side panels 3 becomes an important line of defense to prevent rainwater from damaging electrical components. When rainwater enters the box, the water baffle 25 can effectively prevent rainwater from splashing onto the components, so that the rainwater flows downward along the side wall of the water baffle 25, and finally falls on the inner bottom surface of the box frame 2, and is discharged out of the box through the drainage holes 24, further enhancing the waterproof ability of the distribution box, providing more reliable protection for the electrical components in the box, ensuring the stable operation of the distribution box in a humid or rainy environment, and extending the service life of the equipment.

[0035] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, a heat dissipation hole 26 is opened on one side of the left side panel 3, a cooling fan 27 is fixed on one side of the left side panel 3, an observation hole 28 is opened on the front side of the front box door 4, and a glass 29 is fixed inside the observation hole 28. The front box door 4 and the rear box door 5 both adopt a double-layer structure, and the interior of the front box door 4 and the rear box door 5 are respectively provided with a rock wool insulation layer 30.

[0036] During use, as the electrical components in the distribution box operate for a long time, a large amount of heat is generated. If it cannot be dissipated in time, the temperature inside the box will rise, affecting the performance and life of the electrical components. The staff activates the cooling fan 27, which can accelerate the flow of air in the box and quickly discharge the heat generated inside the box frame 2 out of the box through the heat dissipation holes 26. This active heat dissipation method can effectively reduce the temperature inside the box and maintain the environment inside the box within a suitable temperature range, providing good conditions for the normal operation of the electrical components, improving the heat dissipation efficiency and reliability of the distribution box, and ensuring the stability and safety of the equipment during long-term operation. Through the observation hole 28 and the glass 29, the staff can directly and clearly observe the operating status of the metering unit and other equipment inside the box frame 2 without opening the front box door 4. This not only saves the staff's operating time and improves work efficiency, but also avoids the adverse effects of dust, moisture, etc. that may be introduced by frequently opening the box door on the electrical components inside the box. At the same time, it reduces the safety hazards caused by misoperation, providing a more convenient and safe method for the daily maintenance and management of the distribution box. In a high-temperature environment, the rock wool insulation layer 30 can effectively block external heat from being transferred into the box, reduce the rate of temperature rise in the box, maintain a relatively cool environment in the box, and protect electrical components from damage by high temperatures. In a cold environment, the rock wool insulation layer 30 can also play a role in heat preservation, reduce the loss of heat in the box, and prevent electrical components from experiencing performance degradation or damage due to low temperatures. This thermal insulation design enables the distribution box to maintain a good operating state in different temperature environments, improves the adaptability and reliability of the equipment, and extends the service life of the equipment.

[0037] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
