Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and in particular to an energy management distribution box and a control method thereof. Background Art

[0002] The Energy Management Center will mainly rely on a complete data collection network to obtain important parameters and related energy data of the production process. After processing, analysis and combining with the evaluation of the production process, it will provide real-time online energy system balance information and adjustment decision-making plans to ensure the scientificity, timeliness and rationality of the energy system balance adjustment, thereby improving the level of energy utilization, realizing the optimal allocation and supply of energy in the production process, ensuring the stability and economy of the production and power process systems, and ultimately achieving the goal of improving the overall energy utilization efficiency.

[0003] During the use of the power distribution cabinet, the built-in electrical equipment will generate heat when working. If the heat is not discharged outside the cabinet in time, the heat will continue to accumulate and affect the normal operation of the electrical equipment, which will lead to problems in energy distribution. The traditional heat dissipation method is to install heat dissipation components on the side of the box for heat dissipation, but this method has poor heat dissipation effect and cannot complete short-term cooling and heat dissipation.

[0004] For example, the Chinese patent published as CN202021679622.9 relates to an automatic lighting heat dissipation distribution box, the inner surface of which has an activated carbon filter movably arranged on the first side; the second side has a heat dissipation through hole, and the inner surface of the second side has a heat sink fixedly arranged, the heat sink includes a plurality of heat sinks and a heat dissipation cavity, and the heat dissipation cavity has a heat conduction frame fixedly arranged. Obviously, this heat dissipation method cannot achieve short-term cooling and heat dissipation, which is not conducive to the safe and stable operation of the distribution box.

[0086] In the present application, the filter plate 23 includes a plate body and a filter net, wherein the filter net can filter dust and flying catkins.

[0087] In the above technical solution, when the air supply pipe 14 absorbs the heat inside the box 3, the internal ventilation device can isolate the flying catkins and dust inside the box 3 through the filter plate 23. When the filter plate 23 is taken out, the dust can be cleaned, which reduces the difficulty of maintenance of the distribution box and improves the heat dissipation effect.

[0088] refer to Figure 1 , Figure 2 and Figure 3 A heat dissipation component 6 is also arranged on the side wall of the box body 3, and a rain shield 5 is arranged on the top of the heat dissipation component 6, and the rain shield 5 corresponds to the heat dissipation component 6 one by one; the plate plane of the rain shield 5 is set at an acute angle to the side wall plane of the box body 3.

[0089] refer to Figure 1 and Figure 2 The difference from the embodiment 1 is that the box body 3 in this embodiment further includes a door body 10, and the door body 10 is hinged to the side wall of the box body 3.

[0090] In the present technical solution, the door body 10 is connected to the box body 3 in a hinged manner. When the door body 10 is closed, the door body 10 can just be inserted into the box body 3, thereby ensuring a reliable connection with the box body 3.

[0091] In more detail, a hinge 9 is fixedly mounted on the side of the box body 3, a door body 10 is fixedly mounted on the side of the hinge 9, an anti-collision rubber ring is also fixedly mounted on the side of the door body 10, a handle 11 is fixedly mounted on the side of the door body 10, and the side of the door body 10 is snap-connected to the side of the box body (3).

[0092] The working principle of the present technical solution is as follows: during use, when the temperature inside the box 3 is too high and needs to be cooled, the heat dissipation component 6 and the air inlet component 19 are turned on, and the air inlet component 19 draws the air with a lower external temperature into the air supply duct 14 and circulates through the air supply duct 14. At the same time, the air supply component 17 is turned on and convection is formed with the air inlet component 19 to enhance the circulation of air. At this time, the heat inside the box 3 enters the air supply duct 14 through a number of through holes opened on the side of the air supply duct 14, and the heat is taken out of the box 3 through the air supply duct 14, thereby completing the cooling operation inside the box 3.

[0093] When the air supply pipe 14 absorbs the heat inside the box body 3, it can also isolate the flying catkins and dust inside the box body 3 through the filter plate 23, and the filter plate 23 can be taken out through the handle 24 to clean the dust, which reduces the difficulty of maintenance of the distribution box and improves the heat dissipation effect.

[0094] This embodiment has the following technical effects, including the following two aspects.

[0095] 1. Compared with the prior art, when the temperature inside the box body 3 is too high and needs to be cooled, the distribution box of the present invention opens the air inlet assembly 19, and the air inlet assembly 19 draws the air with a lower external temperature into the air supply pipe 14 and circulates through the air supply pipe 14. At the same time, the air supply assembly 17 is opened to form convection with the air inlet assembly 19 to enhance the circulation of air. At this time, the heat inside the box body 3 enters the air supply pipe 14 through a number of through holes opened on the side of the air supply pipe 14, and is taken out of the box body 3 through the air supply pipe 14, completing the cooling operation inside the box body 3, which can improve the heat dissipation effect of the distribution box, isolate the possibility of external water vapor entering, optimize the convection mode, and improve the safety of the distribution box.

[0096] 2. Compared with the prior art, in the distribution box of the present invention, when the air supply duct 14 absorbs the heat inside the box body 3, it can also isolate the flying catkins and dust inside the box body 3 through the filter plate 23, and the filter plate 23 can be taken out by the handle to clean the dust, which reduces the difficulty of maintenance of the distribution box and improves the heat dissipation effect.
