Description

Technical Field

[0001] This utility model relates to the field of wave absorption research technology, specifically to a splicing structure for a large-area wave-absorbing wall. Background Technology

[0002] During the testing of spacecraft products, the spacecraft emits strong microwaves after activation, which are harmful to the human body. Therefore, it is necessary to use a microwave absorption device to absorb and dissipate the electromagnetic waves directed at the workers, thereby protecting the safety of the workers' working environment.

[0003] Chinese patent application CN202210943871.1 discloses a movable microwave absorbing screen, comprising multiple microwave absorbing screen units. Each microwave absorbing screen unit includes a rectangular support, with an absorbing panel on the front side of the support. A base is located at the bottom of the support, and casters are mounted on the base. This movable microwave absorbing screen facilitates transportation or adjustment of its position via the casters on the base, and simultaneously solves the problem of workers being exposed to microwave environments during experimental work in existing technologies.

[0004] However, the aforementioned movable wave-absorbing screens lack a dedicated splicing and fixing mechanism. When multiple screen units are used side by side, they are spliced ​​only by the side-to-side contact of adjacent screen units, lacking rigid connection or limiting constraint. In practical applications, the following problems are likely to occur: 1) Easily displaced by external forces: Spacecraft test sites often require moving equipment and adjusting test positions. If staff or equipment accidentally collide with screen units, adjacent screen units are prone to lateral displacement or longitudinal misalignment, causing the originally fitting splicing seam to widen and destroying the continuous barrier of wave absorption protection. 2) No microwave absorption treatment at the splicing seam: The sides of adjacent screen units are frame installation structures. The splicing seam formed after they are attached (even if there is no gap initially) is essentially a non-wave-absorbing area. Strong microwaves emitted by spacecraft can easily penetrate through the splicing seam, forming a microwave leakage channel, which exposes staff to a microwave environment that exceeds the safety standard, threatening their health. 3) Difficulty in synchronous movement: When multiple side-by-side screen units need to be repositioned, staff need to push them one by one, making it impossible to achieve synchronous translation or turning of multiple screen units, and uneven pushing force can easily lead to misalignment of the splicing. Utility Model Content

[0005] In order to overcome the problems of easy displacement under external force, lack of wave-absorbing treatment at the splicing seams, and difficulty in synchronous movement of multiple movable wave-absorbing devices used side by side in the prior art, this utility model provides a splicing structure for a large-area wave-absorbing wall.

[0006] The technical solution of this utility model is as follows: A splicing structure for a large-area wave-absorbing wall includes at least two wave-absorbing wall units spliced ​​left and right. Each wave-absorbing wall unit includes a movable base and a wave-absorbing wall disposed on the movable base. The wave-absorbing wall includes a mounting frame and multiple wave-absorbing modules disposed on the front side of the mounting frame. Multiple first splicing fixing holes are provided on the left and right sides of the back side of the mounting frame, which are spaced apart along the height direction of the mounting frame. Two adjacent first splicing fixing holes cooperate with first splicing fixing parts to seamlessly splice and fix the two adjacent wave-absorbing walls.

[0007] As a preferred embodiment of this utility model, the first splicing fastener has two first fixing through holes distributed on the left and right and cooperating with the first splicing fixing hole and the fixing screw.

[0008] As a preferred embodiment of this utility model, the front left and right sides of the movable base are provided with second splicing and fixing holes. The two adjacent second splicing and fixing holes cooperate with the second splicing and fixing components to splice and fix the front ends of the two adjacent movable bases.

[0009] As a preferred embodiment of this utility model, the second splicing fastener has two second fixing through holes distributed on the left and right and cooperating with the second splicing fixing hole and the fixing screw.

[0010] As a preferred embodiment of this utility model, the rear left and right sides of the movable base are provided with third splicing fixing holes. The two adjacent third splicing fixing holes cooperate with the third splicing fixing parts to splice and fix the rear ends of the two adjacent movable bases.

[0011] As a preferred embodiment of this utility model, the third splicing fastener has two third fixing through holes distributed on the left and right and cooperating with the third splicing fixing hole and the fixing screw.

[0012] As a preferred embodiment of this utility model, the left and right sides of the movable base are provided with a plurality of fourth splicing and fixing holes spaced apart in the front-back direction. The two adjacent fourth splicing and fixing holes on the left and right sides cooperate with the fourth splicing and fixing components to splice and fix the middle parts of the two adjacent movable bases on the left and right sides.

[0013] As a preferred embodiment of this utility model, the fourth splicing fastener has two fourth fixing through holes distributed on the left and right and cooperating with the fourth splicing fixing hole and the fixing screw.

[0014] As a preferred embodiment of this utility model, the mounting frame is provided with detachable handles on both the left and right sides.

[0015] As a preferred embodiment of this utility model, the top of the mounting frame is provided with at least two symmetrically distributed lifting lugs.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The splicing structure of the large-area wave-absorbing wall provided by this utility model achieves seamless splicing and fixing of two adjacent wave-absorbing walls by using splicing fasteners in conjunction with two splicing fixing holes of adjacent left and right wave-absorbing wall units. This eliminates the splicing seams formed by the side frames of adjacent wave-absorbing wall units, making the entire large-area wave-absorbing wall a continuous and complete wave-absorbing structure, and enhancing the connection strength and stability between the wave-absorbing walls. When the position needs to be adjusted, the operator only needs to apply a pushing or pulling force to one of the wave-absorbing wall units to drive the entire spliced ​​large-area wave-absorbing wall to move or turn synchronously, without having to push each screen unit one by one. This greatly improves the operating efficiency and reduces the time and workload caused by readjusting the splicing position. Attached Figure Description

[0022] Please see Figures 1 to 4 This utility model provides a splicing structure for a large-area absorbing wall, including at least two absorbing wall units 1 spliced ​​left and right. Each absorbing wall unit 1 includes a movable base 11 and an absorbing wall 12 disposed on the movable base 11. The absorbing wall 12 includes a mounting frame 121 and multiple absorbing modules 122 disposed on the front of the mounting frame 121. Multiple first splicing fixing holes 1211 are provided on the left and right sides of the back of the mounting frame 121, which are spaced apart along the height direction of the mounting frame 121. Two adjacent first splicing fixing holes 1211 cooperate with first splicing fixing parts 2 to seamlessly splice and fix the two adjacent absorbing walls 12.

[0023] In this embodiment, by using the first splicing fastener 2 in conjunction with two adjacent first splicing fastening holes 1211, two adjacent wave-absorbing walls 12 are seamlessly spliced ​​and fixed, eliminating the splicing seam formed by the side frame of the adjacent wave-absorbing wall unit 1. This makes the entire large-area wave-absorbing wall 12 form a continuous and complete wave-absorbing structure. Since the adjacent wave-absorbing walls 12 are rigidly connected, the connection strength and stability between the wave-absorbing walls 12 are enhanced. At the same time, the multiple first splicing fastening holes 1211 are distributed at intervals along the height direction of the mounting frame 121, which can evenly distribute the external force from different heights to the adjacent wave-absorbing walls 12. In addition, since the adjacent wave-absorbing wall units 1 are rigidly connected by the first splicing fastener 2, the multiple left and right spliced ​​wave-absorbing wall units 1 form a whole. When the position needs to be adjusted, the staff only needs to apply a pushing or pulling force to one of the wave-absorbing wall units 1 to drive the entire spliced ​​large-area wave-absorbing wall 12 to move or turn synchronously. There is no need to push each screen unit one by one, which greatly improves the operation efficiency and reduces the time and workload caused by readjusting the splicing position.

[0024] Please see Figure 1 In one embodiment, the first splicing fastener 2 has two first fixing holes 21 distributed on the left and right sides, which cooperate with the first splicing fixing holes 1211 and fixing screws. The two first fixing holes 21 correspond precisely to the first splicing fixing holes 1211 of the adjacent wave-absorbing wall 12. By locking with double screws, it is ensured that the sides of the wave-absorbing wall 12 are completely fitted, thus eliminating the basis for splicing seams from a structural perspective.

[0025] Please see Figure 2 , Figure 4 In one embodiment, the front left and right sides of the movable base 11 are provided with second splicing fixing holes 111. The two adjacent second splicing fixing holes 111 cooperate with the second splicing fixing member 3 to splice and fix the front ends of the two adjacent movable bases 11. By using the second splicing fixing member 3 in conjunction with the two adjacent second splicing fixing holes 111, splicing and fixing at the front end of the movable base 11 is achieved, which further enhances the integrity of the entire large-area absorbing wall 12. When subjected to external forces, such as equipment handling collisions or vibrations during testing, it can better maintain structural stability, reduce the relative displacement between the movable bases 11, and ensure the accurate relative position between the absorbing wall units 1.

[0026] Furthermore, the second splicing fastener 3 has two second fixing holes 31 distributed on the left and right sides, which cooperate with the second splicing fixing holes 111 and fixing screws. The two second fixing holes 31 precisely correspond to the second splicing fixing holes 111 of the adjacent movable bases 11. By locking with double screws, the adjacent movable bases 11 are more firmly spliced ​​at the front end, which can effectively resist the influence of various external forces, prevent the splice from loosening or breaking, ensure the stable connection between the movable bases 11, and thus ensure the structural stability of the entire large-area wave-absorbing wall 12.

[0027] Please see Figure 1 , Figure 3 In one embodiment, the left and right sides of the rear end of the movable base 11 are provided with third splicing fixing holes 112. The two adjacent third splicing fixing holes 112 cooperate with the third splicing fixing component 4 to splice and fix the rear ends of the two adjacent movable bases 11. By using the third splicing fixing component 4 in conjunction with the two adjacent third splicing fixing holes 112, splicing and fixing at the rear end of the movable base 11 is achieved, which further enhances the integrity of the entire large-area absorbing wall 12. When subjected to external forces, such as equipment handling collisions or vibrations during testing, it can better maintain structural stability, reduce the relative displacement between the movable bases 11, and ensure the accurate relative position between the absorbing wall units 1.

[0028] Furthermore, the third splicing fastener 4 has two third fixing holes 41 distributed on the left and right, which cooperate with the third splicing fixing holes 112 and fixing screws. The two third fixing holes 41 precisely correspond to the third splicing fixing holes 112 of the adjacent movable base 11. By locking with double screws, the adjacent movable base 11 is more firmly spliced ​​at the rear end, which can effectively resist the influence of various external forces, prevent the splice from loosening or breaking, ensure the stable connection between the movable base 11, and thus ensure the structural stability of the entire large-area wave-absorbing wall 12.

[0029] Please see Figures 1 to 4 In one embodiment, multiple fourth splicing fixing holes 113 spaced apart along the front-back direction are provided on both the left and right sides of the movable base 11. Two adjacent fourth splicing fixing holes 113 cooperate with the fourth splicing fixing component 5 to splice and fix the two adjacent movable bases 11. By using the fourth splicing fixing component 5 in conjunction with the two adjacent fourth splicing fixing holes 113, splicing and fixing are achieved in the middle of the movable base 11, which further enhances the integrity of the entire large-area absorbing wall 12. When subjected to external forces, such as equipment handling collisions or vibrations during testing, it can better maintain structural stability, reduce the relative displacement between the movable bases 11, and ensure the accurate relative position between the absorbing wall units 1.

[0030] Furthermore, the fourth splicing fastener 5 has two fourth fixing holes 51 distributed on the left and right, which cooperate with the fourth splicing fixing holes 113 and fixing screws. The two fourth fixing holes 51 precisely correspond to the fourth splicing fixing holes 113 of the adjacent movable bases 11. By locking with double screws, the adjacent movable bases 11 are more firmly spliced ​​in the middle, which can effectively resist the influence of various external forces, prevent the splice from loosening or breaking, ensure the stable connection between the movable bases 11, and thus ensure the structural stability of the entire large-area wave-absorbing wall 12.

[0031] Please see Figure 3 , Figure 4 In one embodiment, detachable handles 1212 are provided on both the left and right sides of the mounting frame 121. The detachable handles 1212 provide workers with convenient leverage points, enabling them to easily lift and move the absorber wall unit 1. Whether operated by a single person or in collaboration with multiple people, the handling task can be completed more safely and efficiently, reducing the risk of accidental damage due to unstable leverage during handling, and also reducing the labor intensity of workers. Since the handles are detachable, after installation, if the position of the handles affects the normal use or splicing of the absorber wall 12, workers can easily remove the handles, allowing the absorber wall 12 to better adapt to various complex installation scenarios and meet different practical needs.

[0032] Please see Figure 3 , Figure 4 In one embodiment, the top of the mounting frame 121 is provided with at least two symmetrically distributed lifting lugs 1213. The lifting equipment can be quickly and accurately connected to the wave-absorbing wall unit 1 through the lifting lugs 1213, reducing the preparation time and operational difficulty before lifting, enabling workers to complete the lifting task of the wave-absorbing wall unit 1 more efficiently, shortening the entire installation cycle and improving work efficiency.
