Description

Technical Field

[0001] This utility model relates to the field of shielding cover technology, and in particular to a high-strength shielding cover. Background Technology

[0002] In high-voltage power transmission equipment, shielding covers are often used to protect important components and can play a role in magnetic shielding. Therefore, their use in high-voltage power transmission equipment is indispensable. However, existing shielding covers have some shortcomings: on the one hand, some shielding covers have low strength and are easily deformed or damaged when subjected to external impact or vibration, thus affecting their shielding effect; on the other hand, during long-term operation, the heat generated by the internal electronic components cannot be dissipated in time, which will cause the internal temperature of the shielding cover to rise, thereby affecting the performance and lifespan of the electronic components.

[0003] To address this issue, a high-strength shielding cover is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve the problems of low strength and poor heat dissipation of some shielding covers during long-term operation, this utility model provides a high-strength shielding cover.

[0005] This utility model is achieved using the following technical solution:

[0006] A high-strength shielding cover includes a cover body, a connecting block at the top of the inner part of the cover body for connecting the cover body to an external conductor, a housing on the cover body, the housing covering the cover body, a connecting post at the top of the cover body, a matching slot inside the housing, and threads on the outer peripheral wall of the connecting post, wherein the cover body and the housing are threadedly connected.

[0007] The housing has an internal cavity filled with coolant. The outer peripheral wall of the housing has multiple heat dissipation rings, which are flat, ring-shaped metal rings arranged longitudinally at equal intervals.

[0008] The cover is provided with a slot, and when the shell is connected to the cover, the lower end of the shell is engaged in the slot.

[0009] Multiple locking blocks are provided on the outer peripheral wall at the upper end of the housing, and the locking blocks are arranged along the circumference of the housing axis.

[0010] Two connecting plates are provided on the outer peripheral wall at the bottom of the cover. The connecting plates are arranged symmetrically, and each connecting plate is provided with an adjustment groove.

[0011] The present invention has the following advantages over the prior art:

[0012] 1. By setting up a shell and a cover, this reasonable structural design enhances the connection stability between the cover and the shell, giving the entire shielding cover high strength, enabling it to withstand a certain degree of external impact and vibration, and making it less prone to deformation or damage, thus ensuring the long-term stability of the shielding effect.

[0013] 2. By installing coolant inside the casing, the coolant inside the casing and the heat dissipation ring outside work together to form a highly efficient heat dissipation system. The coolant can quickly absorb internal heat, while the heat dissipation ring accelerates the dissipation of heat, effectively reducing the temperature inside the shielding cover, providing a suitable working environment for the internal electronic components, and extending the service life of the electronic components.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 A high-strength shielding cover includes a cover body 1. A connecting block 15 is located at the top of the interior of the cover body 1, used for connecting the cover body 1 to an external conductor. A housing 2 is mounted on the cover body 1, covering it. A connecting post 12 is located at the top of the cover body 1. A matching slot 11 is located inside the housing 2. Threads are provided on the outer peripheral wall of the connecting post 12, and the cover body 1 and housing 2 are threadedly connected. This threaded connection method is not only secure but also convenient for disassembly; separation from the cover body 1 can be achieved simply by rotating the housing 2.

[0022] The housing 2 has an internal cavity 23 filled with coolant. Multiple heat dissipation rings 22, flat and ring-shaped metal, are arranged longitudinally at equal intervals on the outer peripheral wall of the housing 2. The coolant has excellent thermal conductivity, enabling it to quickly absorb heat generated by internal electronic components. The design of the heat dissipation rings 22 increases the contact area between the housing 2 and the outside air, accelerating heat dissipation. After the coolant transfers heat to the surface of the housing 2, the heat dissipation rings 22 can quickly dissipate the heat to the surrounding environment, effectively reducing the temperature inside the shielding cover.

[0023] The cover 1 is provided with a slot 11. When the shell 2 is connected to the cover 1, the lower end of the shell 2 is engaged in the slot 11. This further enhances the connection stability between the cover 1 and the shell 2, prevents relative movement between the shell 2 and the cover 1 during use, and ensures the overall structural integrity of the shield.

[0024] Multiple locking blocks 21 are provided on the outer peripheral wall of the upper end of the housing 2, and the locking blocks 21 are arranged around the axial circumference of the housing 2. The multiple locking blocks 21 facilitate force application and make it convenient for workers to disassemble the housing 2.

[0025] Two connecting plates 13 are provided on the outer peripheral wall at the bottom of the cover 1. The connecting plates 13 are symmetrically arranged, and each connecting plate 13 is provided with an adjustment groove 14. The design of the connecting plates 13 and the adjustment groove 14 facilitates the installation of the shielding cover into the equipment. The adjustment groove 14 can be used to make fine adjustments according to the actual installation position, ensuring the accuracy and firmness of the shielding cover installation.

[0026] The working principle of this utility model is as follows: When in use, the shielding cover is installed into the corresponding position in the equipment through the connecting plate 13 and the adjustment groove 14 at the bottom of the cover 1. According to the actual installation situation, the position of the shielding cover is finely adjusted through the adjustment groove 14 to ensure accurate and firm installation.

[0027] During normal operation of electronic equipment, the shielding cover can effectively shield external electromagnetic interference and protect internal electronic components. At the same time, the coolant inside the housing 2 continuously absorbs the heat generated by the electronic components and dissipates the heat to the surrounding environment through the heat dissipation ring 22, maintaining a suitable temperature inside the shielding cover.

[0028] When maintenance or repair of electronic equipment is required, simply rotate the housing 2 using the locking block 21 to separate the housing 2 from the cover 1, and you can easily operate the inside of the shield or the electronic equipment. After maintenance is completed, reinstall the housing 2 onto the cover 1 according to the above assembly process.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
