Description
Technical Field
[0001] The utility model relates to the technical field of radiation protection of energy storage cabinets, in particular to an energy storage cabinet shell that is resistant to radiation interference. Background Art
[0002] Energy storage cabinets are devices used to store electrical energy and are widely used in power generation, communications, and data centers. Because they contain a large number of electrical devices, they are susceptible to interference from external electromagnetic radiation during operation, which can affect the normal operation of the equipment and even cause equipment failure. Electromagnetic interference can cause signal distortion and errors in electronic equipment, reducing system reliability and safety. Therefore, effectively protecting energy storage cabinets from electromagnetic interference has become a key research topic.
[0003] Currently, one of the methods for energy storage cabinets to prevent radiation interference is to use conductive grounding parts to ground the shell to guide the electromagnetic interference signal to quickly discharge to the ground and prevent it from accumulating inside the equipment. However, during the transportation of the energy storage cabinet, due to the uneven ground, the conductive grounding parts may not be able to effectively contact the ground, resulting in the inability to achieve radiation protection throughout the transportation process. In the prior art, some designs use conductive chains to contact the ground. Although the chain can always maintain contact with the ground during transportation, the chain has some disadvantages during use. First, the chain is easily stuck by obstacles on the ground, resulting in unstable grounding; second, because the chain is composed of multiple links, each link will collide with each other during movement, and produce friction and impact with the ground. These physical contacts will generate large noises, affecting the quietness of the operating environment. For this reason, there is an urgent need for those skilled in the art to make improvements. Utility Model Content

[0005] To achieve the above-mentioned purpose, the energy storage cabinet shell for radiation interference prevention proposed in the present invention includes a shell body, a conductive grounding rod and a conductive elastic member. The shell body is made of electromagnetic shielding material, and an installation cavity and a through-hole are formed on the bottom wall of the shell body. The through-hole is connected to the installation cavity, and the through-hole is formed with a first opening on the outer surface of the bottom wall of the shell body; the conductive grounding rod is movably arranged in the through-hole, one end of the conductive grounding rod is arranged in the installation cavity, and the other end of the conductive grounding rod extends out of the shell body through the first opening; the conductive elastic member is arranged in the installation cavity, one end of the conductive elastic member is connected to the cavity wall of the installation cavity, and the other end of the conductive elastic member is connected to the conductive grounding rod, and the conductive elastic member drives the conductive grounding rod to move in the direction from the installation cavity to the first opening, so that the conductive grounding rod elastically abuts against the ground.
[0006] Optionally, the via hole is formed with a second opening on the cavity wall of the mounting cavity;
[0007] The conductive grounding rod includes a rod body and a conductive cover, wherein the rod body is disposed in the through hole, one end of the rod body passes through the second opening and is connected to the conductive cover in the mounting cavity, and the other end of the rod body extends out of the housing body through the first opening;
[0008] The side wall of the conductive cover facing away from the rod body is connected to the conductive elastic member, and the orthographic projection of the conductive cover covers the second opening.
[0009] Optionally, a first guide column is protruding from the side wall of the conductive cover facing away from the rod body, the length direction of the first guide column is parallel to the axial direction of the through hole, the conductive elastic member is a conductive spring, and part of the structure of the conductive spring sleeve is sleeved on the first guide column.
[0010] Optionally, one of the peripheral wall of the through hole and the outer peripheral wall of the rod body is provided with a guide groove, and the other is provided with a guide block, the guide groove extends in the axial direction of the through hole, and the guide block can be slidably inserted into the guide groove.
[0011] Optionally, in the direction from the second opening to the first opening, the width of the guide groove gradually decreases, and the maximum width of the guide block is set to be greater than the minimum width of the guide groove to limit the guide block from escaping from the end opening of the guide groove.
[0012] Optionally, a second guide post is provided on the cavity wall of the installation cavity, the length direction of the second guide post is parallel to the axial direction of the through hole, the conductive elastic member is a conductive spring, and part of the structure of the conductive spring sleeve is sleeved on the second guide post.
[0013] The radiation interference-proof energy storage cabinet housing of the utility model technical solution has the following advantages:
[0014] A conductive elastic member is located within the mounting cavity, with one end connected to the cavity wall and the other end to the conductive grounding rod. This member drives the rod in the direction from the mounting cavity to the opening, allowing it to elastically contact the ground. This design feature, through the elastic force of the elastic member, ensures that the rod always maintains close contact with the ground. Regardless of the unevenness of the ground, the rod automatically adjusts its position under the drive of the elastic member, ensuring a good grounding effect. This design not only improves grounding stability but also effectively prevents electromagnetic radiation interference during transportation of the energy storage cabinet.
[0015] Furthermore, conductive chains are prone to getting caught on obstacles on the ground during use, resulting in unstable grounding. This problem does not occur with conductive grounding rods. This is because conductive chains are composed of multiple links and are easily entangled or caught when encountering obstacles. A conductive grounding rod, however, is a cylindrical structure with a relatively smooth, curved surface, making it less susceptible to small obstacles on the ground. Furthermore, because a chain is composed of multiple links, each link will collide with each other during movement, generating friction and impact with the ground. This physical contact generates significant noise. A conductive grounding rod, however, is a single, rigid structure without the multiple links of a chain. Therefore, it avoids the problem of interlinkages. This single, rigid structure maintains continuous, smooth contact with the ground during movement, without producing noticeable clashing noise. Furthermore, the conductive grounding rod is designed to maintain constant elastic contact with the ground through the use of a conductive elastic member. The elastic force of the conductive elastic member not only ensures the rod maintains close contact with the ground but also absorbs some of the vibration and impact caused by uneven ground during movement, further reducing noise.

[0029] The utility model provides an energy storage cabinet shell that is resistant to radiation interference.
[0030] In the embodiment of the present utility model, Figures 1 to 6 As shown, the radiation interference-proof energy storage cabinet shell includes a shell body 1, a conductive grounding rod 2 and a conductive elastic member 3. The shell body 1 is made of electromagnetic shielding material. A mounting cavity 11 and a through-hole 12 are formed on the bottom wall of the shell body 1. The through-hole 12 is connected to the mounting cavity 11, and the through-hole 12 is formed with a first opening 13 on the outer surface of the bottom wall of the shell body 1; the conductive grounding rod 2 is movably arranged in the through-hole 12, one end of the conductive grounding rod 2 is arranged in the mounting cavity 11, and the other end of the conductive grounding rod 2 extends out of the shell body 1 through the first opening 13; the conductive elastic member 3 is arranged in the mounting cavity 11, one end of the conductive elastic member 3 is connected to the cavity wall of the mounting cavity 11, and the other end of the conductive elastic member 3 is connected to the conductive grounding rod 2. The conductive elastic member 3 drives the conductive grounding rod 2 to move in the direction from the mounting cavity 11 to the first opening 13, so that the conductive grounding rod 2 elastically abuts against the ground.
[0031] Specifically, the electromagnetic shielding material can be a metal material such as copper, aluminum, or stainless steel. The conductive grounding rod 2 should be made of a material with good conductivity, such as copper, aluminum, or silver-plated steel. The conductive elastic member 3 can be implemented in various ways, such as a spring, an elastic metal gasket, or a conductive rubber elastomer.
[0032] When the conductive elastic part 3 contacts the shell body 1 and the conductive grounding rod 2, a conductive path is formed, so that the electromagnetic interference signal on the shell body 1 is quickly discharged to the ground. In addition, when the conductive grounding rod 2 moves in the through hole 12, the wall of the through hole 12 of the shell is in direct contact with the conductive grounding rod 2, ensuring that the shell body 1 forms multiple conductive paths with the conductive grounding rod 2 through the conductive elastic part 3 and the wall of the through hole 12.
[0033] It can be understood that in the radiation interference-proof energy storage cabinet housing of the present invention, the conductive elastic member 3 is arranged in the installation cavity 11, one end is connected to the cavity wall of the installation cavity 11, and the other end is connected to the conductive grounding rod 2, and drives the conductive grounding rod 2 to move in the direction from the installation cavity 11 to the opening, so that the conductive grounding rod 2 elastically abuts against the ground. This design feature ensures that the conductive grounding rod 2 can always maintain close contact with the ground through the elastic force of the conductive elastic member 3. No matter how uneven the ground is, the conductive grounding rod 2 can automatically adjust its position under the drive of the conductive elastic member 3 to ensure a good grounding effect. This design not only improves the stability of the grounding, but also enables the energy storage cabinet to continuously and effectively prevent electromagnetic radiation interference during transportation.
[0034] Furthermore, while the conductive chain can easily get caught on obstacles on the ground during use, resulting in unstable grounding, the conductive grounding rod 2 does not experience this problem. This is because the conductive chain is composed of multiple links and is easily entangled or stuck when encountering obstacles. The conductive grounding rod 2, on the other hand, is a cylindrical structure with a relatively smooth, curved surface, making it less susceptible to small obstacles on the ground. Furthermore, since the chain is composed of multiple links, each link will collide with each other during movement, causing friction and impact with the ground. This physical contact generates significant noise, while the conductive grounding rod 2 is a single, rigid structure without the multiple links of a chain. Therefore, the problem of collision between links is eliminated. This single, rigid structure maintains continuous and smooth contact with the ground during movement, without producing noticeable clashing noise. Furthermore, the conductive grounding rod 2 is designed to maintain continuous elastic contact with the ground through the drive of the conductive elastic member 3. The elastic force of the conductive elastic member 3 not only ensures that the conductive grounding rod 2 maintains close contact with the ground but also absorbs some of the vibration and impact caused by uneven ground during movement, further reducing noise generation.
[0035] Optionally, the via hole 12 is formed with a second opening 14 on the cavity wall of the mounting cavity 11;
[0036] The conductive grounding rod 2 includes a rod body 21 and a conductive cover 22. The rod body 21 is disposed in the through hole 12. One end of the rod body 21 passes through the second opening 14 and is connected to the conductive cover 22 in the mounting cavity 11. The other end of the rod body 21 extends out of the housing body 1 through the first opening 13.
[0037] The side wall of the conductive cover 22 facing away from the rod body 21 is connected to the conductive elastic member 3 , and the orthographic projection of the conductive cover 22 covers the second opening 14 .
[0038] Specifically, the conductive cover 22 can be a circular or square metal sheet, and the orthographic projection of the conductive cover 22 covers the second opening 14, which means that when observed from a direction perpendicular to the conductive cover 22 (usually along the axial direction of the via 12), the outline of the conductive cover 22 completely covers the outline of the second opening 14.
[0039] The design of the conductive cover 22 prevents the conductive grounding rod 2 from detaching from the housing body 1. Furthermore, because the conductive cover 22 is larger than the via 12, it can abut against the wall of the mounting cavity 11 when the housing body 1 is not being moved, driven by the conductive elastic member 3, thereby quickly discharging electromagnetic interference signals from the housing body 1 to the conductive grounding rod 2.
[0040] Optionally, a first guide column 23 is protruded from the side wall of the conductive cover 22 facing away from the rod body 21, the length direction of the first guide column 23 is parallel to the axial direction of the through hole 12, the conductive elastic member 3 is a conductive spring, and part of the structure of the conductive spring sleeve is sleeved on the first guide column 23.
[0041] In specific implementation, the first guide post 23 can be made of the same metal material as the conductive cover 22, such as copper or aluminum, and the length of the guide post is parallel to the axis of the via 12. The conductive spring can be made of a highly conductive material such as phosphor bronze or beryllium copper.
[0042] In this embodiment, the provision of the first guide post 23 ensures that the conductive spring can move along a fixed path during expansion and contraction without deviation. This structural design enables the elastic force of the conductive spring to effectively act on the conductive cover 22, thereby pushing the conductive grounding rod 2 to maintain a stable grounding effect.
[0043] Optionally, one of the peripheral wall of the through hole 12 and the outer peripheral wall of the rod body 21 is provided with a guide groove 15, and the other is provided with a guide block 24, the guide groove 15 extends in the axial direction of the through hole 12, and the guide block 24 can be slidably inserted into the guide groove 15.
[0044] The guide groove 15 can be provided on the peripheral wall of the via hole 12, while the guide block 24 can be provided on the outer peripheral wall of the conductive grounding rod 2, or vice versa. The guide groove 15 extends along the axis of the via hole 12, thereby effectively controlling and guiding the movement direction and position of the conductive grounding rod 2 within the via hole 12.
[0045] By providing guide grooves 15 and guide blocks 24 on the peripheral wall of the through hole 12 and the outer peripheral wall of the conductive grounding rod 2, it is ensured that the conductive grounding rod 2 can slide along a predetermined path in the through hole 12, ensuring smooth and accurate movement of the conductive grounding rod 2.
[0046] The material of the guide block 24 can have good conductivity, such as copper, aluminum or silver-plated steel. By contacting the guide block 24 with the groove wall of the guide groove 15, the contact area between the shell body 1 and the conductive grounding rod 2 can be further increased, ensuring that the electromagnetic interference signal can be effectively transmitted from the shell body 1 to the conductive grounding rod 2.
[0047] Optionally, in the direction from the second opening 14 to the first opening 13, the width of the guide groove 15 gradually decreases, and the maximum width of the guide block 24 is set to be greater than the minimum width of the guide groove 15 to limit the guide block 24 from escaping from the end opening of the guide groove 15.
[0048] The maximum width of the guide block 24 refers to its largest dimension perpendicular to its sliding direction. The width of the conductive block is parallel to the width of the conductive slot. By designing the maximum width of the guide block 24 to be greater than the minimum width of the guide slot 15, the guide block 24 becomes stuck when it moves to the narrowest part of the guide slot 15, preventing it from being released. This design ensures that the conductive grounding rod 2 is properly detached from the housing body 1, ensuring reliable installation of the conductive grounding rod 2.
[0049] Optionally, a second guide column 16 is provided on the cavity wall of the installation cavity 11 , the length direction of the second guide column 16 is parallel to the axial direction of the through hole 12 , the conductive elastic member 3 is a conductive spring, and part of the structure of the conductive spring sleeve is sleeved on the second guide column 16 .
[0050] The second guide post 16 can be made of the same or similar metal material as the wall of the mounting cavity 11. By providing the second guide post 16 on the wall of the mounting cavity 11 and sleeve-mounting the conductive spring portion thereon, the conductive spring can be ensured to move along a fixed path during expansion and contraction without deflection or bending.
[0051] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
