Description

Technical Field

[0001] This utility model belongs to the technical field of safety relay testing equipment, specifically a portable protection structure for frame-type safety relay testing equipment. Background Technology

[0002] As a core safety component of industrial automation control systems, safety relays, with their redundant design and forced-guided contacts, can quickly cut off dangerous circuits when equipment experiences overload, short circuits, or other abnormalities, protecting the safety of personnel and equipment. Their importance is particularly evident in wind turbines. Wind turbines stand at high altitudes and in the field year-round, enduring harsh environments such as strong winds, lightning, extreme temperatures and humidity, and sandstorms. Safety relays in the main control, pitch, and yaw systems need to monitor key parameters such as wind speed and current in real time. Once an abnormality such as overspeed or overvoltage is detected, the protection mechanism must be triggered immediately to prevent major accidents such as wind turbine runaway or circuit fires.

[0003] Safety relay testing equipment is a key tool to ensure the reliable performance of safety relays in wind turbines. Common testing instruments are characterized by their small size, light weight, and portability, making it convenient for maintenance personnel to carry them to remote wind farms and climb hundreds of meters up the wind turbine nacelle to conduct on-site testing.

[0004] Wind farms are mostly located in remote mountainous areas and coastal mudflats where transportation is inconvenient. Maintenance personnel need to carry equipment through long and bumpy transportation, and when operating in the narrow space inside the wind turbine nacelle, the equipment is very prone to falling. Existing portable safety relay testing equipment often uses a simple shell design for protection, lacking effective cushioning protection measures. Some equipment only has ordinary rubber pads pasted on the corners. Such pads cannot provide both hardness and elasticity, making it difficult to withstand high-intensity impacts. In addition, common protective structures are mostly fixed to the equipment and matched to the equipment structure, making it difficult to apply to equipment of different types and sizes.

[0005] Therefore, a portable protection structure for frame-type safety relay testing equipment is proposed to address the above issues. Utility Model Content

[0006] To address the problems mentioned in the background section, this utility model provides a portable protection structure for a frame-type safety relay testing device, which has the advantages of enhanced protection and applicability to devices of different sizes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable protection structure for a frame-type safety relay testing device, including protective corner pieces located at the four corners of the safety relay tester, with adjacent protective corner pieces connected by an adjustable telescopic rod;

[0008] The protective corner piece includes a first corner piece and a second corner piece arranged symmetrically front to back. The first corner piece and the second corner piece are connected by a spacing adjustment component. Rubber protrusions are provided on the side of the first corner piece and the second corner piece that are far apart from each other.

[0009] Both the first corner piece and the second corner piece include an L-shaped plate. The outer and inner sides of the L-shaped plate are respectively provided with an outer rubber pad and an inner rubber pad. The inner side of the inner rubber pad is provided with a retaining edge near the edge.

[0010] Preferably, the adjusting telescopic rod includes a threaded tube, both ends of which are threaded with threaded rods, and the end of the threaded rod away from the threaded tube is fixedly connected to an L-shaped plate.

[0011] Preferably, the outer wall of the threaded tube is provided with anti-slip ridges.

[0012] Preferably, the spacing adjustment assembly includes a threaded cylinder and a through pipe respectively embedded in the front and rear L-shaped plates. The threaded cylinder is threadedly connected to a long bolt, and the bolt of the long bolt passes through the through pipe and is threadedly connected to the threaded cylinder.

[0013] Preferably, the bolt head of the long bolt is embedded in its corresponding rubber protrusion.

[0014] Preferably, the outer rubber pad has rubber protrusions on its outer side.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model sets up protective corner pieces. Both the first and second corner pieces adopt a double-layer structure design with an outer rubber pad and an inner rubber pad, forming a double protection mechanism of "buffering first and shock absorption later". The outer rubber pad has a slightly higher hardness and strong wear resistance and tear resistance, which can effectively disperse the impact force at the moment of equipment collision. The inner rubber pad has a lower hardness and excellent elasticity, which can convert the impact force transmitted by the outer layer into its own deformation energy, absorb high-frequency vibration, and protect the precision components inside the equipment.

[0017] 2. This utility model can be fixed on devices of different lengths, widths and heights by setting an adjustable telescopic rod and a spacing adjustment component, so as to expand the range of use. When not in use, it can also be reduced in size and disassembled for easy storage. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1 to 5 As shown, this utility model provides a portable protection structure for a frame-type safety relay testing device, including protective corner pieces 1 located at the four corners of the safety relay tester, and adjacent protective corner pieces 1 are connected by an adjusting telescopic rod 2.

[0033] The protective corner piece 1 includes a first corner piece 11 and a second corner piece 12 symmetrically arranged front and back. The first corner piece 11 and the second corner piece 12 are connected by a spacing adjustment component 13. Rubber protrusions 14 are provided on the side of the first corner piece 11 and the second corner piece 12 that are far apart from each other. The first corner piece 11 and the second corner piece 12 both adopt a double-layer structure design of outer rubber pad 112 and inner rubber pad 113, forming a double protection mechanism of "buffering first and shock absorption later". The outer rubber pad 112 has a slightly higher hardness and strong wear resistance and tear resistance. It can effectively disperse the impact force at the moment of equipment collision. The inner rubber pad 113 has a lower hardness and excellent elasticity. It can convert the impact force transmitted by the outer layer into its own deformation energy, absorb high-frequency vibration, and protect the precision components inside the equipment.

[0034] Both the first corner piece 11 and the second corner piece 12 include an L-shaped plate 111. The L-shaped plate 111 serves as the skeleton support for the rubber pad and is made of high-strength engineering plastic or lightweight alloy, providing a stable installation base for the rubber pad. When the equipment is subjected to a side impact, the L-shaped plate 111 can evenly distribute the impact force to the entire corner piece, preventing the rubber pad from being deformed or falling off due to excessive local stress. At the same time, the L-shaped design has a higher fit with the corner of the equipment and can provide a larger buffer area in a limited space compared to a planar protective structure, further improving the protective effect. An outer rubber pad 112 and an inner rubber pad 113 are respectively provided on the outer and inner sides of the L-shaped plate 111. A retaining edge 114 is provided on the inner side of the inner rubber pad 113 near the edge.

[0035] Specifically, the adjustable telescopic rod 2 includes a threaded tube 21, both ends of which are threadedly connected to threaded rods 22. The end of the threaded rod 22 away from the threaded tube 21 is fixedly connected to an L-shaped plate 111. The adjustable telescopic rod 2 can adjust the length and width of the structural frame to match the corresponding length and width of the equipment.

[0036] Furthermore, the outer wall of the threaded tube 21 is provided with anti-slip ridges 23 to facilitate rotation of the threaded tube 21.

[0037] Furthermore, the spacing adjustment assembly 13 includes a threaded cylinder 131 and a through pipe 132 respectively embedded in the front and rear L-shaped plates 111. The threaded cylinder 131 is threadedly connected to a long rod bolt 133. The screw of the long rod bolt 133 passes through the through pipe 132 and is threadedly connected to the threaded cylinder 131. The spacing adjustment assembly 13 can adjust the distance between the first corner piece 11 and the second corner piece 12 to match the corresponding thickness of the equipment.

[0038] It is worth noting that the bolt head of the long bolt 133 is embedded in its corresponding rubber protrusion 14.

[0039] It is worth noting that the outer rubber pad 112 has rubber ridges 115 on its outer side to improve its impact resistance.

[0040] Working principle and process: Both the first corner piece 11 and the second corner piece 12 of the protective corner piece 1 adopt a double-layer structure design with an outer rubber pad 112 and an inner rubber pad 113, forming a dual protection mechanism of "buffering first and shock absorption later". The outer rubber pad 112 has a slightly higher hardness and strong wear resistance and tear resistance, which can effectively disperse the impact force at the moment of equipment collision. The inner rubber pad 113 has a lower hardness and excellent elasticity, which can convert the impact force transmitted by the outer layer into its own deformation energy, absorb high-frequency vibration, and protect the precision components inside the equipment. The L-shaped plate 111, as the skeleton support of the rubber pad, is made of high-strength engineering plastic or lightweight alloy, providing a stable installation base for the rubber pad. When the equipment is hit from the side, the L-shaped plate 111 can evenly distribute the impact force to the entire corner piece, avoiding excessive local stress on the rubber pad, which may cause deformation or detachment. At the same time, the L-shaped plate 111 can also evenly distribute the impact force to the entire corner piece. The design fits the edges and corners of the equipment better, providing a larger buffer area in a limited space compared to a planar protective structure, further enhancing the protective effect. The adjustable telescopic rod 2 can adjust the length and width of the structural frame to match the corresponding length and width of the equipment. The spacing adjustment component 13 can adjust the distance between the first corner piece 11 and the second corner piece 12 to match the corresponding thickness of the equipment, thereby expanding the range of use. When not in use, it can also be reduced in size and disassembled for easy storage.
