Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a distribution box with wind and sand protection function. Background Technology

[0002] In power systems, distribution boxes, as core equipment for power distribution and control, are widely used in various outdoor environments. However, in areas with high wind and sand intensity, traditional distribution boxes face numerous problems during use.

[0003] On the one hand, the air inlet structure of traditional distribution boxes is simple, usually a simple straight hole or filter design; when operating in a sandy environment, sand particles can easily enter the distribution box with the airflow; the sand particles that enter the box will not only deposit on the surface of the components, affecting the heat dissipation effect, causing the equipment to overheat and degrade in performance or even fail, but may also cause problems such as poor electrical contact, affecting the stable operation of the power system.

[0004] On the other hand, even if existing windproof and sandproof distribution boxes adopt some sand-filtering structures, after long-term use, the air intake channel is easily blocked by sand particles, which may lead to a significant reduction in air intake, poor air circulation inside the box, and failure to meet the heat dissipation requirements of the components inside the distribution box, which may increase maintenance costs and frequency. Utility Model Content

[0025] 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.

[0026] Example 1:

[0027] Reference Figures 1-4 A distribution box with wind and sand protection function includes a box body 1, an exhaust filter plate 101 fixedly connected to the side wall of the box body 1, and further includes:

[0028] The air inlet filter plate 2 is fixedly connected to the side wall of the housing 1, and the air inlet filter plate 2 and the air outlet filter plate 101 are symmetrically arranged.

[0029] Air inlet 201 is located on air inlet filter plate 2;

[0030] The air inlet 201 is a conical hole, and the diameter of the air inlet end of the air inlet 201 is larger than the diameter of the air outlet end.

[0031] An electric push rod 4 is fixedly connected to the housing 1 via a support plate 102. A push plate 3 is fixedly connected to the drive end of the electric push rod 4. A push rod 301 is fixedly connected to the push plate 3. The diameter of the push rod 301 is smaller than the diameter of the air outlet end of the air inlet 201.

[0032] Reference Figures 1-5 In actual use, through the air inlet filter plate 2 and the air outlet filter plate 101 set on both sides of the housing 1, the outside air will enter the housing 1 through the air inlet hole 201 on the air inlet filter plate 2, and after flowing through the components inside the housing 1, it will be discharged through the air outlet hole on the air outlet filter plate 101.

[0033] It should be noted that the diameter of the exhaust port near the electric push rod 4 is larger than the diameter of the exhaust port away from the electric push rod 4.

[0034] In practical implementation, by setting the air inlet 201 as a conical hole, and the diameter of the air inlet end of the air inlet 201 is larger than the diameter of the air outlet end, the wind speed will increase when the outside air enters the box 1, thereby improving the cooling effect on the components inside the box 1.

[0035] Reference Figures 1-5 In actual use, some sand particles from the outside will move synchronously with the wind. Through the conical air inlet hole 201 set on the air inlet filter plate 2, the sand particles can be effectively trapped and prevented from entering the box 1.

[0036] Reference Figures 3-5After a period of use, the electric push rod 4 on the support plate 102 will work. At this time, the electric push rod 4 will push the push plate 3 connected to its drive end to move. The movement of the push plate 3 will drive the push rod 301 fixedly connected to it to move. When the push rod 301 moves a certain distance, the push rod 301 will extend into the air inlet hole 201. At this time, the push rod 301 will push out the sand particles stuck in the air inlet hole 201, thereby ensuring that the sand particles will not be stuck in the air inlet hole 201 and affect the air intake.

[0037] The conical air inlet 201 in the device can increase the air intake speed and ensure the cooling effect. At the same time, the movable push rod 301 in the device can effectively push out the sand particles stuck in the air inlet 201, reduce the possibility of the air inlet 201 being blocked, and ensure the air intake volume.

[0038] A slide bar 202 is fixedly connected to the air inlet filter plate 2, and an impact plate 2022 is fixedly connected to the slide bar 202.

[0039] A tension spring 203 is fixedly connected to the impact plate 2022, and the end of the tension spring 203 away from the impact plate 2022 is fixedly connected to the air inlet filter plate 2.

[0040] A limit plate 2021 is fixedly connected to the slide bar 202.

[0041] The push plate 3 has a clearance hole 302. The diameter of the clearance hole 302 is larger than the diameter of the limiting plate 2021, and the diameter of the clearance hole 302 is smaller than the diameter of the impact plate 2022.

[0042] Reference Figure 5 By setting the clearance hole 302, it can be ensured that the push plate 3 will not hit the limit plate 2021 when it moves, and can stably push the impact plate 2022 to slide.

[0043] Reference Figure 5 In practice, the impact plate 2022 is a magnetic plate and the push plate 3 is an iron plate, and the impact plate 2022 and the push plate 3 are attracted to each other.

[0044] When the push plate 3 pushes the push rod 301 to push out the sand particles stuck in the air inlet 201, the push plate 3 will simultaneously push the impact plate 2022 to slide on the slide rod 202. When the push plate 3 moves to its maximum limit, the electric push rod 4 will drive the push plate 3 to reset and retract. At this time, the push plate 3 will drive the impact plate 2022, which is attracted to it, to slide synchronously. After the impact plate 2022 slides a certain distance, under the limiting action of the limiting plate 2021, the impact plate 2022 will separate from the push plate 3. At this time, under the reset pulling force of the tension spring 203, the impact plate 2022 will slide back quickly. At this time, the impact plate 2022 will hit the air inlet filter plate 2, thereby shaking off any impurities that may remain on the outer wall of the air inlet filter plate 2, further improving the cleaning effect of the air inlet filter plate 2 and ensuring that sand particles will not clog the air inlet 201.

[0045] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[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 inventive concept of the present utility model, should be included within the protection scope of the present utility model.
