Description

Technical Field

[0001] The invention relates to the technical field of distribution box equipment, in particular to a distribution box with an autonomous heat dissipation mechanism. Background Art

[0002] The distribution box is a massive parameter in data. It is generally composed of low-voltage electrical wiring, which requires the assembly of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen to form a low-voltage distribution box. There are many electrical components in the distribution box, so the distribution box needs to dissipate heat when in use. The distribution boxes currently used in the market have heat dissipation holes on their side ends. In windy and rainy weather, rainwater is easily blown into the heat dissipation holes by the wind, causing the inside of the distribution box to become damp. Severe accidents may be caused by short circuits, and the protection effect is poor.

[0003] After searching, the Chinese patent "A distribution box with protective function", authorization announcement number "CN113824016B" uses a sealing mechanism to seal the heat dissipation port when it rains, preventing rainwater from entering the distribution box body, thereby enhancing the protective effect of the distribution box body; the heat dissipation mechanism dissipates heat inside the distribution box body when the heat dissipation port is blocked, and further enhances the heat dissipation of the distribution box body through the water cooling pipe, thereby increasing the sealing of the distribution box body and ensuring its heat dissipation effect;

[0004] Although the above application can protect the distribution box and prevent rainwater from entering the device when it rains, the distribution box relies on external wind or motor drive for conventional ventilation and heat dissipation, which increases the difficulty of conventional ventilation and heat dissipation. At the same time, it lacks autonomous heat dissipation function and cannot self-adjust the heat dissipation state according to the temperature conditions inside the distribution box, affecting the heat dissipation performance of the distribution box.

[0037] Combine the following Figure 1-Figure 8 The invention describes a distribution box with an autonomous heat dissipation mechanism.

[0038] In one embodiment, a distribution box with an autonomous heat dissipation mechanism includes:

[0039] A box body 100, an electric push rod 200 and a top cover 300, wherein the electric push rod 200 is arranged between the box body 100 and the top cover 300, a controller 400 is arranged at the bottom end of the top cover 300, a raindrop sensor 600 is arranged at the middle of the top end of the top cover 300, and a temperature sensor 500 is arranged in the box body 100;

[0040] Multiple vents are provided on both sides of the box 100. A cooling fan 110 is provided at the top of the box 100. A frame 311 used in conjunction with the cooling fan 110 is fixedly connected to the bottom of the top cover 300. Top air inlet plates 312 are provided around the frame 311.

[0041] The heat dissipation device 700 includes a plurality of heat dissipation plates 710 which are rotatably connected to both sides of the box body 100 and used in conjunction with the vents. A side air inlet plate 711 is provided on the heat dissipation plate 710. A sliding frame 713 is fixedly connected to one side of the heat dissipation plate 710. A slider 714 is slidably connected inside the sliding frame 713. A vertical plate 712 is provided inside the box body 100. A hinge rod 715 is hinged between the slider 714 and the vertical plate 712. A connecting rod 718 is fixedly connected to the bottom end of the top cover 300. The other end of the connecting rod 718 passes through the frame body 311, the heat dissipation fan 110 and the box body 100 in sequence. A gear 716 is provided inside the box body 100. A rack 717 meshing with the gear 716 is fixedly connected to the other end of the connecting rod 718 and the top end of the vertical plate 712.

[0042] like Figure 2 and Figure 3 As shown, a sealing ring 310 for use with the cooling fan 110 is disposed at the middle of the bottom end of the top cover 300 . The middle of the sealing ring 310 is hollow and is made of rubber material.

[0043] In this embodiment, when the top cover 300 descends, the sealing ring 310 will fit tightly against the upper edge of the cooling fan 110, thereby increasing the sealing performance between the two and improving the protective performance of the device in a closed state.

[0044] In one embodiment, Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the heat dissipation device 700 also includes two L-shaped plates 721 respectively fixedly connected to the two sides of the inner wall of the box body 100, and a plurality of through openings are opened on the L-shaped plates 721. The opposite sides of the two L-shaped plates 721 are slidably connected with a blocking plate 722, and the side of the blocking plate 722 away from the L-shaped plate 721 is fixedly connected with a plurality of trigger blocks 723, and the opposite sides of the two vertical plates 712 are fixedly connected with a toggle plate 720 used in conjunction with the trigger block 723, and a strip opening is provided on the L-shaped plate 721.

[0045] A collection frame 724 is provided between the L-shaped plate 721 and the inner wall of the box body 100, and the collection frame 724 is in close contact with the inner bottom wall of the box body 100. When the ventilation opening area is increased, impurities are collected, making it more convenient to clean and maintain them later.

[0046] In this embodiment, the toggle plate 720 will move downward synchronously with the vertical plate 712, the trigger block 723 will lose its blocking force, and the blocking plate 722 will automatically fall under the action of gravity to block the through-hole, and the cooling fan 110 will be started. The external air will enter from the gap between the heat dissipation plate 710 and the vent and the side air inlet plate 711. Under the blocking of the L-shaped plate 721, the external gas will reach the top from the lower part of the box body 100, and be discharged through the gap between the cooling fan 110 and the frame body 311, forming a new ventilation channel, thereby achieving rapid ventilation and heat dissipation.

[0047] In one embodiment, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the heat dissipation device 700 also includes a cylinder body 731 arranged in the heat dissipation plate 710, a piston rod 732 is provided in the cylinder body 731, one end of the piston rod 732 passes through the cylinder body 731 and is fixedly connected to a baffle 733 used in conjunction with the side air inlet plate 711, and the inner top wall of the sliding frame 713 is provided with an air bag 730 connected to the cylinder body 731.

[0048] A second spring 734 is provided between the piston rod 732 and the cylinder body 731, and a first spring 7141 is fixedly connected to the bottom end of the slider 714, and one end of the first spring 7141 away from the slider 714 is fixedly connected to the inner wall of the slide frame 713. The first spring 7141 can limit the position of the slider 714, and cooperates with the second spring 734 to provide a reset force, so that the device is smoother when switching between multiple states without offset or conflict.

[0049] In this embodiment, the hinge rod 715 is moved upward, the slider 714 squeezes the airbag 730, and the gas enters the cylinder 731 to squeeze the piston rod 732. The piston rod 732 moves downward, and the baffle 733 is used to block the side air inlet plate 711 to prevent external rainwater from entering the box body 100, thereby achieving all-round closure of the ventilation opening of the box body 100, increasing the sealing protection performance, and preventing the infiltration of rainwater.

[0050] In one embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the heat dissipation device 700 also includes a cooling pipe 741 arranged in the box body 100, and two interconnected water collecting frames 740 are arranged at the bottom end of the top cover 300, one end of the cooling pipe 741 is connected to the water collecting frame 740, and the other end of the cooling pipe 741 is connected to the drain pipe 742.

[0051] The middle part of the cooling pipe 741 is spiral in shape, and the height of the connection between the cooling pipe 741 and the drain pipe 742 is greater than the height of the bending part of the cooling pipe 741. This ensures that the cooling pipe 741 is filled with rainwater, and realizes unpowered rainwater replacement, thereby improving the effect of rainwater heat dissipation.

[0052] The box body 100 is provided with a transverse pipe 743 connected to the cooling pipe 741, and a solenoid valve is provided at the bottom end of the transverse pipe 743. The cooperation between the transverse pipe 743 and the solenoid valve can be used to discharge rainwater in the cooling pipe 741, ensuring that the rainwater can be completely discharged.

[0053] The top of the top cover 300 is ridge-shaped, a detachable isolation plate 744 is provided at the top of the water collecting frame 740, and a plurality of protective plates 120 used in conjunction with the heat sink 710 are provided on both sides of the box body 100. The isolation plate 744 can prevent impurities from entering the collecting frame 724, ensuring that the cooling pipe 741 will not be blocked, and the protective plate 120 can protect the connection between the heat sink 710 and the box body 100 to prevent rainwater from seeping in from there.

[0054] In this embodiment, rainwater from the outside will gather on the top cover 300. Affected by its shape, rainwater will enter the cooling pipe 741 from the water collecting frame 740. Under the limitation of its shape, the cooling pipe 741 will be quickly filled and in a full state. When water continues to flow in and the water volume continues to increase, the water at a high water level will enter the drain pipe 742 and be discharged, thereby replacing the cooling water. By utilizing the heat absorption and discharge of the cooling water, the box body 100 can be cooled and dissipated in a fully enclosed protective state, thereby ensuring the normal and stable operation of the device.

[0055] Working principle: The application will be operated in three states in actual use, and its specific form selection will be based on the cooperation between the temperature sensor 500, the raindrop sensor 600 and the controller 400;

[0056] When the temperature detected by the temperature sensor 500 is within the normal preset value range, conventional ventilation and heat dissipation can be performed. A heat dissipation channel is formed between the side air inlet plate 711, the strip opening and the top air inlet plate 312, and the device can perform conventional ventilation and heat dissipation. The heat dissipation fan 110 can also be started. Under the guidance of the heat dissipation fan 110, the external cold air will enter from the side air inlet plate 711 at the heat dissipation plate 710, and will be discharged after passing through the through opening, the heat dissipation fan 110, the frame 311 and the top air inlet plate 312 in sequence, thereby accelerating the air flow and quickly dissipating the heat. The air duct direction that accelerates the heat dissipation is in the vicinity. Figure 2 It is clearly stated in

[0057] When the temperature detected by the temperature sensor 500 exceeds the normal preset value range, the controller 400 will start the electric push rod 200, which drives the top cover 300, the frame 311, and the top air inlet plate 312 to move upward as a whole, so that the frame 311 is separated from the cooling fan 110. At the same time, the top cover 300 will drive the connecting rod 718 and the corresponding rack 717 to move upward, driving the gear 716 to rotate, and the other rack 717 will move downward, driving the vertical plate 712 to move downward, and the hinged rod 715 will push the heat sink 710 to rotate. The slider 714 and the sliding frame 713 will rotate during this process. The air inlet 710 is provided with a plurality of air intake ports, and the air inlet 710 is provided with a plurality of air intake ports, and the air intake ...

[0058] For example, when the raindrop sensor 600 detects that it is raining outside, the controller 400 is used to start the electric push rod 200. The electric push rod 200 drives the top cover 300, the frame 311 and the top air inlet plate 312 to move downward synchronously until the sealing ring 310 is completely in contact with the cooling fan 110. The connecting rod 718 moves downward synchronously. Under the action of the gear 716, another rack 717 drives the vertical plate 712 to move upward. The hinge rod 715 moves upward to achieve the fit between the cooling plate 710 and the box 100. The sliding block 714 will squeeze the airbag 730, and the gas will enter the cylinder 731 to squeeze the piston rod 732. The piston rod 732 Move downward and use the baffle 733 to seal the side air inlet plate 711 to prevent external rainwater from entering the box body 100. At the same time, the external rainwater will gather on the top cover 300. Affected by its shape, the rainwater will enter the cooling pipe 741 from the water collecting frame 740. Under the limitation of its shape, the cooling pipe 741 will be quickly filled and in a full state. When water continues to flow in and the water volume continues to increase, the water at a high water level will enter the drain pipe 742 and be discharged, thereby realizing the replacement of cooling water. The heat absorption and discharge of cooling water are used to dissipate heat for the box body 100.

[0059] It should be noted that the box 100, cooling fan 110, electric push rod 200, controller 400, temperature sensor 500 and raindrop sensor 600 in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the cooling fan 110, electric push rod 200, controller 400, temperature sensor 500 and raindrop sensor 600 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0060] Note: The cooling fan 110 in the application is a mounting frame and a fan that cooperate with each other to achieve the final installation. The fan is installed in the mounting frame, and the mounting frame is fixedly connected and communicated with the box body 100. The connecting rod 718 moves in the gap between the mounting frame and the fan. Therefore, when the connecting rod 718 is adjusted, there will be no conflict between them.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
