Problems solved by technology

[0003] Although the existing absorbing structure can effectively absorb reflected waves and clutter to a certain extent, but because it can only be fixed at a designated position, the height and horizontal position cannot be adjusted, resulting in a greatly reduced range of absorbing waves. Limited; and the existing absorbing structure cannot be spliced ​​and installed quickly and easily, and the practicability is low

Embodiment 1

[0045] This embodiment provides a wave absorbing device, which includes a lifting component, a lateral moving component, and a wave absorbing component for absorbing electromagnetic waves.

[0046] Specifically, such as figure 1 and figure 2 As shown, the lateral movement assembly includes a support frame 1 and a first power source 2. The wave-absorbing assembly is slidably arranged on the support frame 1. The first power source 2 drives the wave-absorbing assembly to perform horizontal reciprocating movements on the support frame 1. The wave-absorbing assembly The range of absorbing electromagnetic waves in the horizontal direction is widened by means of horizontal reciprocating motion. In order to realize the sliding arrangement of the wave absorbing component on the support frame, a T-shaped slot can be set on the upper surface of the support frame, and the bottom of the wave absorbing component is slidably set in the T-shaped slot. At this time, the first power source driv...

Embodiment 2

[0077] The difference from Embodiment 1 is that the outer side of the upper side of the control frame is provided with a third tooth, which saves the tooth plate structure, and the third tooth is engaged with the control gear for transmission, thereby realizing the transmission connection between the control frame and the control gear. Make the transmission structure simpler.

Embodiment 3

[0079] The difference from Embodiment 1 is that, in order to facilitate the processing of the wave absorbing device, the auxiliary block and the auxiliary ball are manufactured in one piece.

Abstract

The invention discloses a wave absorbing device. The wave absorbing device comprises a lifting assembly, a lateral moving assembly and a wave absorbing assembly used for absorbing electromagnetic waves. Wherein the lateral moving assembly comprises a supporting frame and a first power source, the wave absorbing assembly is arranged on the supporting frame in a sliding mode, and the first power source is used for driving the wave absorbing assembly to do horizontal reciprocating motion; the lifting assembly comprises a second power source, and the second power source is used for driving the supporting frame to do vertical reciprocating motion. In the wave absorbing device, the wave absorbing assembly can perform horizontal reciprocating motion and vertical reciprocating motion, and the range of absorbing electromagnetic waves is larger.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic wave absorption, and in particular relates to a wave absorbing device. Background technique [0002] In the process of testing the wave transmission rate of the broadband EW radome, since the working frequency of the EW test antenna is usually 20Ghz ~ 40Ghz, many reflected waves will be formed between the EW test antenna and the EW radome. Under the interference of reflected waves and clutter, the wave transmission rate of the tested electronic warfare radome will exceed 100, which will affect the real electrical performance of the electronic warfare radome. Therefore, it is necessary to set up a wave-absorbing structure to effectively eliminate the reflected waves and clutter formed between the electronic warfare test antenna and the electronic warfare radome. [0003] Although the existing absorbing structure can effectively absorb reflected waves and clutter to a certain extent, but be...
