Description

Technical Field

[0001] This utility model relates to the field of power distribution control technology, and in particular to a heat dissipation mechanism for power distribution control equipment. Background Technology

[0002] Power distribution control equipment is a key component in power systems used for distributing, controlling, protecting, and monitoring electrical energy. It is widely used in industrial, commercial, residential, and infrastructure sectors. Its core function is to ensure the safe and efficient transmission of electrical energy to end users, while simultaneously protecting equipment and personnel.

[0003] Power distribution control equipment generates a significant amount of heat during operation. To ensure stable operation, cooling measures must be implemented. Currently, the most common cooling structures on the market employ a combination of a cooling fan and a filter. The cooling fan draws airflow from the outside into the equipment enclosure, while the filter removes dust particles from the airflow. There are two main installation methods for the filter: one is to install it on the outer wall of the equipment enclosure, and the other is to install it inside the enclosure.

[0004] When the filter is installed on the outer wall of the enclosure, it comes into direct contact with rainwater, causing dust particles on the filter to stick together under the influence of rainwater, leading to premature clogging. For filters installed inside the enclosure, to prevent dust generated during cleaning from entering the enclosure through the cooling fan ducts and causing secondary pollution, the filter needs to be removed for cleaning. However, removing the filter requires disassembling the enclosure, making the process cumbersome and significantly increasing the workload. To address these issues, this improved solution was developed. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation mechanism for power distribution control equipment. This heat dissipation mechanism is easier to clean and can reduce secondary pollution to the equipment, making it more reliable and practical.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heat dissipation mechanism for power distribution control equipment, comprising a housing with an inner cavity, a cooling fan, and a filter screen. A heat dissipation cavity communicating with the inner cavity is formed inside the housing. An air inlet communicating with the outside is formed on the heat dissipation cavity. The cooling fan is mounted on the heat dissipation cavity and is not facing upwards. An opening and closing structure is provided on the air inlet. A sliding structure is provided between the housing and the filter screen. The sliding structure has a working position where the filter screen is inside the heat dissipation cavity and a cleaning position where it is outside the housing. A linkage structure connects the filter screen and the opening and closing structure. When the filter screen is in the working position, the opening and closing structure is in the open state. When the filter screen is in the cleaning position, the opening and closing structure is in the closed state.

[0007] By adopting the above technical solution, and by placing the filter screen inside the heat dissipation cavity and configuring the air inlet to not face upwards, dust particles on the filter screen will not come into contact with rainwater and stick. When cleaning the filter screen is required, the filter screen is switched from the working position to the cleaning position, and then the opening and closing mechanism is switched from the open state to the closed state under the action of the linkage mechanism. This ensures that during the cleaning process, dust particles will not enter the inner cavity of the housing through the air inlet via the heat dissipation cavity, and this structure also eliminates the need to disassemble the filter screen from the housing. This makes cleaning the heat dissipation mechanism more convenient and reduces secondary pollution to the equipment, making it more reliable and practical.

[0008] The opening and closing structure is further configured as an opening and closing cover that rotates within the heat dissipation cavity via a rotating shaft.

[0009] By adopting the above technical solution, the opening and closing structure can be switched between the open and closed states by rotating the opening and closing cover.

[0010] The sliding structure is further configured such that it is positioned on one side of the heat dissipation cavity along the orthogonal projection direction of the air inlet, and the pivot of the opening and closing cover is positioned in the heat dissipation cavity away from the sliding structure.

[0011] By adopting the above technical solution, this configuration structure, in conjunction with the linkage structure, forms a linkage between the sliding filter and the opening and closing cover.

[0012] The sliding structure is further configured as follows: the sliding structure includes a slide rail disposed on the heat dissipation cavity wall and extending out of the air inlet at one end, and a slide column fixedly disposed on the filter screen and slidingly engaged with the slide rail.

[0013] By adopting the above technical solution, the filter screen slides in the slide channel through the sliding column, and by setting one end of the slide channel to extend out of the air inlet, the filter screen located in the heat dissipation cavity can slide out of the heat dissipation cavity to the outside of the box, so as to carry out the subsequent filter screen cleaning operation.

[0014] The linkage structure is further configured as follows: the linkage structure is a positioning elastic element that connects the opening and closing cover. When the filter screen is in the working position, the filter screen is in the open state against the opening and closing cover.

[0015] By adopting the above technical solution, the filter screen located in the heat dissipation cavity abuts against the top of the opening and closing cover and compresses the positioning elastic element, so that the opening and closing cover is in the open state. When the filter screen moves out of the heat dissipation cavity, it loses the abutting force of the filter screen, so that the opening and closing cover rotates to the closed state under the drive of the positioning elastic element and closes the air inlet.

[0016] The slide bar and the slide rail are further configured to form both a sliding fit and a rotational fit.

[0017] By adopting the above technical solution, when the filter screen slides to the outside of the housing through the cooperation of the sliding column and the sliding track, the filter screen can be cleaned conveniently and thoroughly by rotating it, making the cleaning operation of the filter screen more convenient.

[0018] A further configuration is provided: when the filter is in the working position, the heat dissipation cavity is provided with a positioning component for positioning the filter.

[0019] By adopting the above technical solution, the stability of the filter screen when it is in the working position is ensured by setting positioning components, thereby ensuring the feasibility of the setting structure.

[0020] The positioning component is further configured as follows: the positioning component includes an upper elastic positioning block disposed on the side wall of the slide and a lower elastic positioning block and positioning edge disposed on the opening and closing cover and located on both sides of the filter screen.

[0021] By employing the above technical solution, the cooperation of the upper elastic positioning block, the lower elastic positioning block, the positioning edge, and the end of the slide rail restricts the sliding of the filter screen, keeping it in a stable filtration state and thus ensuring the reliability of the filtration. Applying force to the filter screen allows it to slide past the upper and lower elastic positioning blocks, thereby avoiding structural interference.

[0022] The air inlet is further configured to face one side in a horizontal direction.

[0023] By adopting the above technical solution, this setup method is more convenient to operate.

[0024] A further configuration is provided: when the filter is in the working position, a pull frame is fixedly installed on the side of the filter facing the air inlet.

[0025] By adopting the above technical solution, the pull frame provides a force point for manual operation of the filter screen, making the operation more convenient.

[0026] In summary, this utility model has the following beneficial effects: it makes cleaning more convenient and reduces secondary pollution to equipment, making it more reliable and practical. Attached Figure Description
