Description

Technical Field

[0001] This application belongs to the field of electrical equipment and relates to a control cabinet top. Background Technology

[0002] Control cabinets are enclosed or semi-enclosed enclosures used in industrial automation systems to house and protect electrical components, electronic equipment, and control devices. They are typically used to centrally manage and protect various types of switching equipment, relays, contactors, circuit breakers, programmable logic controllers (PLCs), human-machine interfaces (HMIs), power supply units, and other related control and signal processing hardware. Some control cabinets are used outdoors, where they are exposed to rain and snow. Most existing outdoor distribution box solutions use a relatively sealed top structure to protect the cabinet from rain and snow. However, in practice, heat generated by the electrical equipment inside the control cabinet accumulates at the top. Current solutions to this problem typically involve ventilation holes on the sides of the cabinet, which are ineffective at dissipating heat from the top. Therefore, a new control cabinet top design is needed to address this issue. Summary of the Invention

[0003] The purpose of this application is to design a control cabinet top to solve the problem of control cabinets being affected by rain and snow when used outdoors.

[0004] Technical solution to achieve the purpose of this application:

[0005] This application provides a control cabinet top, including: a top plate, a rotating structure, a spring, a rotating tube, a cover, a wind resistance structure, a movable scraping structure, and a pull rope;

[0006] The top plate is provided with openings;

[0007] The rotating structure is rotatably mounted below the opening in the top plate, and a spring is connected to the rotating structure, with the upper end of the spring connected to the rotating tube.

[0008] A cover is fixedly installed on the upper end of the rotating tube, and the cover has a through hole with the same inner diameter as the rotating tube.

[0009] A wind resistance structure is slidably installed on the cover, and a movable scraping structure that can move up and down is provided below the wind resistance structure, with its lower surface in contact with the top plate.

[0010] A pull rope is connected to the wind resistance structure, and the pull rope passes through the rotating tube and is connected to the rotating structure.

[0011] The cover is open on the side facing the wind resistance structure, which is used to form a top air outlet channel;

[0012] When wind is generated, the wind resistance structure deflects under the action of wind pressure, causing the cover to automatically turn to the leeward side to prevent rain and snow from entering the control cabinet. At the same time, the wind resistance structure generates traction force on the rotating structure through the pull rope, compressing the spring and causing the cover to drop as a whole to reduce the opening size, thereby achieving coordinated control of rain protection and heat dissipation.

[0013] Optionally, the rotating structure includes a collection pool, a bearing, and a mounting tube;

[0014] A bearing is installed inside the collection tank. The outer ring of the bearing is fixedly connected to the collection tank, and the inner ring is connected to the lower end of the pull rope and spring. An installation pipe is installed below the top plate, and the collection tank is fixed on the installation pipe.

[0015] Optionally, the bottom of the collection pool is connected to a discharge pipe, with the inner end of the discharge pipe communicating with the bottom of the collection pool and the outer end extending to the outside of the top plate for draining accumulated water.

[0016] Optionally, four limiting posts are installed on the lower surface of the cover. The four limiting posts are distributed in a square, and the distance between their outer sides is less than or equal to the diameter of the opening in the top plate.

[0017] Optionally, the top plate opening edge is provided with a rising edge, the inner diameter of which is the same as the opening diameter.

[0018] Optionally, the wind resistance structure includes a guide groove and a deflector fan. The guide groove is opened on the upper part of the cover, and the deflector fan is slidably installed in the guide groove. The deflector fan is a vertical plate-shaped structure.

[0019] Optionally, tension plates are provided on both sides of the tail end of the deflection fan. The tension plates and the deflection fan are not parallel and are both vertical plate structures.

[0020] Optionally, the movable scraping structure includes a guide rod and a movable scraper. The guide rod is fixedly installed above the cover, and the movable scraper is slidably sleeved on the guide rod.

[0021] The beneficial technical effects of this application are as follows:

[0022] This invention provides a control cabinet top with the following beneficial effects: Through its structural design, when wind is present, the cover deflects under the action of the wind resistance structure, causing the open portion of the cover to face the wind resistance structure side, i.e., the leeward side. This prevents external airflow from entering the control cabinet and thus avoids rain and snow from entering. Simultaneously, under the pulling action of the wind resistance structure, the structure drives the pull rope, which in turn pulls the rotating structure along the rotating tube, generating a reaction force that acts on the cover, compressing the spring and causing the cover to... The overall height of the body is reduced, decreasing the size of the opening on the open side of the cover. This, combined with the installation of an exhaust fan below the opening of the cover, increases the airflow speed, further preventing rain and snow from entering during heavy rain and snow. The control cabinet can still dissipate heat during rain and snowfall. Furthermore, when the cover rotates, the movable scraping structure rotates, effectively removing snow from the top surface of the top plate. Thus, this device retains the top-exhaust cooling method for the indoor control cabinet, dissipating heat from the top of the cabinet while preventing rain and snow from entering, maintaining heat dissipation even in rainy, snowy, and windy weather.

[0031] To enable those skilled in the art to better understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only a part of the embodiments of this application, and not all of them. Based on the embodiments described in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1-6 This invention provides a technical solution: a control cabinet top, including a top plate 1, a rotating structure, a spring 2, a rotating tube 3, a cover 4, a wind resistance structure, a movable scraping structure, and a pull rope 5. The top plate 1 has an opening, and the rotating structure is rotatably installed below the opening. The spring 2 is connected to the rotating structure, and the upper end of the spring 2 is connected to the rotating tube 3. The cover 4 is fixedly installed at the upper end of the rotating tube 3. The cover 4 has an opening with the same inner diameter as the rotating tube 3. The wind resistance structure is slidably installed on the cover 4. The movable scraping structure is installed on the cover 4 below the wind resistance structure. The movable scraping structure is a structure whose lower surface is movable in the vertical direction and contacts the top plate 1. The pull rope 5 is connected to the wind resistance structure, and the pull rope 5 passes through the rotating tube 3 and connects to the rotating structure. The side of the cover 4 facing the wind resistance structure is an open structure.

[0033] In this invention, the rotating structure includes a collection pool 6, a bearing 7, and an installation tube 8. The bearing 7 is installed inside the collection pool 6. The outer ring of the bearing 7 is connected to the collection pool 6, and the inner ring of the bearing 7 is connected to the lower end of the pull rope 5 and the spring 2. The installation tube 8 is installed below the top plate 1, and the collection pool 6 is installed on the installation tube 8. The rotational friction is reduced by the bearing 7.

[0034] In this invention, the bottom of the collection pool 6 is connected to a discharge pipe 9. The inner end of the discharge pipe 9 is connected to the bottom of the collection pool 6 and the outer end extends to the outside of the top plate 1. The collection pool 6 collects water that flows in along the installation pipe 8 and discharges it outward through the discharge pipe 9.

[0035] In this invention, four limiting posts 10 are installed on the cover 4. The four limiting posts 10 are arranged in a square and installed on the inner lower surface of the cover 4. The distance between the outer sides of the limiting posts 10 is less than or equal to the diameter of the opening on the top plate 1. The limiting posts 10 guide the up and down movement of the cover 4.

[0036] In this invention, a rising edge 11 is installed on the top plate 1. The rising edge 11 is installed on the opening part of the top plate 1, and its inner diameter is the same as the opening diameter. The rising edge 11 can block rain and snow on the top plate 1.

[0037] In this invention, the wind resistance structure includes a guide groove 12 and a deflecting fan 13. The upper part of the cover 4 has a guide groove 12, and the deflecting fan 13 is slidably installed in the guide groove 12. The deflecting fan 13 is a vertical plate structure. The guide groove 12 guides the deflecting fan 13 so that the wind can deflect when it acts on the deflecting fan 13.

[0038] In this invention, tension plates 14 are installed on both sides of the tail end of the deflector fan 13. The tension plates 14 and the deflector fan 13 are not parallel and are vertical plate structures. The tension plates 14 increase the force of the wind on the deflector fan 13, which facilitates the movement of the pull rope 5.

[0039] In this invention, the movable scraping structure includes a guide rod 15 and a movable scraper 16. The guide rod 15 is fixedly installed on the upper part of the cover 4, and the movable scraper 16 is slidably mounted on the guide rod 15. The movable scraper 16 scrapes the surface of the top plate 1 when the cover 4 rotates. The movable scraper 16 can change position as the cover 4 rises and falls.

[0040] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0041] In this implementation plan:

[0042] When working, when there is wind, the cover 4 deflects under the action of the wind resistance structure, so that the open part of the cover 4 faces the side of the wind resistance structure, that is, the leeward side, thus preventing the outside airflow from entering the control cabinet and causing rain and snow to enter. At the same time, under the pulling action of the wind resistance structure, the wind resistance structure drives the pull rope 5 to move, and the pull rope 5 pulls the rotating structure along the rotating tube 3, thus generating a reaction force acting on the cover 4, which in turn compresses the spring 2, causing the overall height of the cover 4 to decrease, reducing the size of the opening on the open side of the cover 4. In conjunction with the exhaust fan installed below the opening of the cover 4, the air speed of the exhaust increases, further preventing rain and snow from entering in windy, rainy, or snowy weather. It can still achieve heat dissipation of the control cabinet during rain and snowfall. When the cover 4 rotates, the cover 4 drives the movable scraping structure to rotate, which has a certain scraping effect on the snow accumulation on the upper surface of the top plate 1.

[0043] The present application has been described in detail above with reference to the accompanying drawings and embodiments. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present application.
