Description

Technical Field

[0001] This utility model relates to the field of wave absorption research technology, specifically to a balancing device for moving wave-absorbing walls. 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 number CN202210943871.1 discloses a movable wave-absorbing screen, comprising multiple wave-absorbing screen units. Each wave-absorbing screen unit includes a rectangular support, with a wave-absorbing panel on the front side of the support; a base is provided at the bottom of the support, and casters are provided on the base. This movable wave-absorbing screen is conveniently transported or its position adjusted via the casters on the base.

[0004] However, the bottom support structure of the aforementioned movable absorbing screen relies solely on the base and casters, resulting in a limited support surface area. When applied to larger absorbing screens / walls (rather than small screens), the existing base alone can easily cause tilting, swaying, or even tipping over during movement due to a shift in the center of gravity or insufficient support surface. This cannot guarantee the stability of large absorbing screens / walls during movement, posing safety hazards and affecting testing efficiency. Utility Model Content

[0005] In order to overcome the problem that the existing movable wave-absorbing devices have limited support surfaces and cannot guarantee the stability of moving large-sized wave-absorbing walls, this utility model provides a balancing device for moving wave-absorbing walls.

[0006] The technical solution of this utility model is as follows: A balancing device for moving a wave-absorbing wall includes a movable base, the wave-absorbing wall being vertically mounted on the movable base, a first movable wheel being provided at the bottom of the movable base, a front telescopic frame that can extend forward and a rear telescopic frame that can extend backward being provided at the front and rear ends of the movable base, respectively, a second movable wheel being provided at the bottom of the front end of the front telescopic frame, and a third movable wheel being provided at the bottom of the rear end of the rear telescopic frame.

[0007] As a preferred embodiment of this utility model, the bottom of the movable base is provided with a front telescopic slide groove that cooperates with the front telescopic frame and a rear telescopic slide groove that cooperates with the rear telescopic frame.

[0009] As a preferred embodiment of the present invention, the front telescopic frame includes two first telescopic slide rods that cooperate with the front telescopic slide groove and a first connecting rod disposed between the front ends of the two first telescopic slide rods, and the bottom of the front ends of the two first telescopic slide rods are provided with second moving wheels.

[0010] As a preferred embodiment of this utility model, the cross-sections of the first telescopic slide rod and the front telescopic slide groove are both rectangular.

[0011] As a preferred embodiment of this utility model, the first telescopic slide rod is provided with a first waist-shaped hole at the front, middle and rear positions to cooperate with the bolt fastener. The movable base is provided with a first fixing hole at the front and rear positions corresponding to the front telescopic slide groove to cooperate with the first waist-shaped hole, so that the movable base can fix the telescopic position of the front telescopic frame through the bolt fastener.

[0012] As a preferred embodiment of this utility model, the rear telescopic frame includes two second telescopic slide rods that cooperate with the rear telescopic slide groove and a second connecting rod disposed between the rear ends of the two second telescopic slide rods.

[0022] Please see Figures 1 to 4 This utility model provides a balancing device for moving a wave-absorbing wall, including a movable base 1. The wave-absorbing wall 2 is vertically mounted on the movable base 1. The four corners of the bottom of the movable base 1 are provided with first moving wheels 11. The movable base 1 serves as the basic support structure of the entire device, providing a stable mounting platform for the wave-absorbing wall 2, ensuring that the wave-absorbing wall 2 can be vertically and stably mounted on it, and reasonably distributing the weight of the wave-absorbing wall 2 to the moving wheels below, ensuring the basic balance of the entire device during movement. The movable base 1 has a forward-extending telescopic frame 3 and a rear-extending telescopic frame 4 at its front and rear ends, respectively. The front end of the front telescopic frame 3 has a second moving wheel 31, and the rear end of the rear telescopic frame 4 has a third moving wheel 41. The second moving wheels 31, the third moving wheels 41, and the first moving wheels 11 together form multiple support points, further expanding the support surface, making the device more stable during movement, effectively bearing the weight of the large-sized wave-absorbing wall 2, and preventing tipping.

[0023] In this embodiment, by providing a forward-extending front telescopic frame 3 and a rear telescopic frame 4 at the front and rear ends of the movable base 1 respectively, the support range of the device can be flexibly adjusted according to actual needs. When the absorber wall 2 is large, extending the front telescopic frame 3 and / or the rear telescopic frame 4 effectively increases the support surface area of ​​the device, enhancing its stability during movement. When not in use, the front telescopic frame 3 and the rear telescopic frame 4 can be retracted, reducing the space occupied by the device and facilitating storage and transportation. This satisfies the stable movement requirements of the large-size absorber wall 2 while avoiding the problem of inconvenient operation of the device in narrow spaces.

[0024] Please see Figure 4 In one embodiment, the bottom of the movable base 1 is provided with a front telescopic groove 12 that cooperates with the front telescopic frame 3 and a rear telescopic groove 13 that cooperates with the rear telescopic frame 4. The front telescopic groove 12 and the rear telescopic groove 13 provide precise tracks for the telescopic movement of the front telescopic frame 3 and the rear telescopic frame 4, ensuring that the telescopic frame can move along a predetermined straight line during the telescopic process, avoiding deviation, shaking, or jamming of the telescopic frame during movement, and improving the accuracy and stability of the telescopic operation. At the same time, through the cooperation of the grooves and the telescopic frame, the telescopic structure is cleverly integrated into the movable base 1, making the entire device more compact and saving space.

[0025] Please see Figure 4 In one embodiment, two front telescopic slides 12 and two rear telescopic slides 13 are provided, and the front telescopic slides 12 and rear telescopic slides 13 are staggered. The two front telescopic slides 12 and the two rear telescopic slides 13 support the front telescopic frame 3 and the rear telescopic frame 4 from different positions, increasing the connection points and support area between the telescopic frame and the movable base 1. The staggered arrangement of the front telescopic slides 12 and the rear telescopic slides 13 can increase their length, making their maximum length equal to the front-to-back length of the movable base 1, thereby maximizing the telescopic range of the front telescopic frame 3 and the rear telescopic frame 4.

[0026] Please see Figure 2 , Figure 3In one embodiment, the front telescopic frame 3 includes two first telescopic sliding rods 32 that cooperate with the front telescopic sliding groove 12 and a first connecting rod 33 disposed between the front ends of the two first telescopic sliding rods 32. Each of the two first telescopic sliding rods 32 has a second moving wheel 31 at its bottom front end. The two first telescopic sliding rods 32 are connected together by the first connecting rod 33, forming a stable frame structure, which enhances the overall strength and rigidity of the front telescopic frame 3. During the movement of the wave-absorbing wall 2, it can better withstand the weight of the wave-absorbing wall 2 and various external forces, and is less prone to deformation or damage, ensuring the reliability and safety of the device. The cross-sections of both the first telescopic sliding rods 32 and the front telescopic sliding groove 12 are rectangular. The rectangular cross-section design ensures that the first telescopic sliding rods 32 can only perform linear telescopic movement within the front telescopic sliding groove 12, preventing rotation. This effectively avoids positional displacement of the front telescopic frame 3 due to rotation during telescopic movement, ensuring that the front telescopic frame 3 can accurately telescopic in the predetermined direction, improving the operational accuracy and stability of the device.

[0027] Please see Figures 2 to 4 In one embodiment, the first telescopic slide rod 32 is provided with first oblong holes 321 at its front, middle, and rear positions to mate with bolt fasteners. The movable base 1 is provided with first fixing holes 14 at its front and rear positions corresponding to the front telescopic slide groove 12, to mate with the first oblong holes 321. Through the cooperation of the bolt fasteners with the first oblong holes 321 and first fixing holes 14 at different positions, the movable base 1 securely fixes the telescopic position of the front telescopic frame 3, preventing accidental extension or swaying of the front telescopic frame 3 during the movement of the wave-absorbing wall 2, thus ensuring the stability and safety of the device. At the same time, this fixing method is simple, reliable, and easy to operate and maintain. The design of the first oblong hole 321 allows the telescopic position of the front telescopic frame 3 to be flexibly adjusted within a certain range, and facilitates the alignment of the first fixing hole 14 with the first oblong hole 321.

[0028] Please see Figure 2 , Figure 3In one embodiment, the rear telescopic frame 4 includes two second telescopic sliding rods 42 that cooperate with the rear telescopic sliding groove 13 and a second connecting rod 43 disposed between the rear ends of the two second telescopic sliding rods 42. Each of the rear ends of the two second telescopic sliding rods 42 is provided with a third moving wheel 41. The two second telescopic sliding rods 42 are connected together by the second connecting rod 43, forming a stable frame structure, which enhances the overall strength and rigidity of the rear telescopic frame 4. During the movement of the wave-absorbing wall 2, it can better withstand the weight of the wave-absorbing wall 2 and various external forces, and is less prone to deformation or damage, ensuring the reliability and safety of the device. The cross-sections of both the second telescopic sliding rods 42 and the rear telescopic sliding groove 13 are rectangular. The rectangular cross-section design ensures that the second telescopic sliding rods 42 can only perform linear telescopic movement within the rear telescopic sliding groove 13, and cannot rotate. This effectively avoids positional displacement of the rear telescopic frame 4 due to rotation during telescopic movement, ensuring that the rear telescopic frame 4 can accurately telescopic in the predetermined direction, improving the operational accuracy and stability of the device.

[0029] Please see Figures 2 to 4 In one embodiment, the second telescopic slide rod 42 is provided with second oblong holes 421 at its front, middle, and rear positions to mate with bolt fasteners. The movable base 1 is provided with second fixing holes 15 at its front and rear positions corresponding to the rear telescopic slide groove 13, to mate with the second oblong holes 421. Through the engagement of the bolt fasteners with the second oblong holes 421 and second fixing holes 15 at different positions, the movable base 1 securely fixes the telescopic position of the rear telescopic frame 4, preventing accidental extension or swaying of the rear telescopic frame 4 during the movement of the wave-absorbing wall 2, thus ensuring the stability and safety of the device. Simultaneously, this fixing method is simple, reliable, and easy to operate and maintain. The design of the second oblong holes 421 allows for flexible adjustment of the telescopic position of the rear telescopic frame 4 within a certain range and facilitates alignment of the second fixing holes 15 with the second oblong holes 421.

[0030] Please see Figures 2 to 4In one embodiment, the top of the movable base 1 is provided with a mounting groove 16 for mounting the absorber wall 2. The movable base 1 has multiple third fixing holes 17 corresponding to the mounting groove 16 for fixing the absorber wall 2. The mounting groove 16 provides a clear and pre-defined spatial position for the installation of the absorber wall 2, enabling operators to quickly and accurately place the absorber wall 2 in the correct position, avoiding problems such as tilting or offset of the absorber wall 2 due to inaccurate installation, thus improving installation efficiency and accuracy. Simultaneously, the sidewalls of the mounting groove 16, when embedded in the absorber wall 2, provide a certain degree of limitation and support, preventing the absorber wall 2 from swaying or moving horizontally. After the absorber wall 2 is embedded in the mounting groove 16, it is fixed to the movable base 1 by using bolts or other fasteners passing through the third fixing holes 17, forming multiple fixing points and firmly connecting the absorber wall 2 to the movable base 1.

[0031] Please see Figure 1 In one embodiment, the rear end of the movable base 1 and the back of the wave-absorbing wall 2 are provided with a support rod 5. The support rod 5 forms a stable triangular support structure between the rear end of the movable base 1 and the back of the wave-absorbing wall 2, which can effectively resist the external forces acting on the wave-absorbing wall 2 in the horizontal and vertical directions, such as bumps, collisions or wind during the movement, and prevent the wave-absorbing wall 2 from shaking, tilting or even falling over, which greatly improves the structural stability of the entire device.

[0032] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
