specific Embodiment approach

[0035] Specific implementation method: First, insert the dielectric material hollow post 7 into the rectangular waveguide cylinder 1, and insert the I-shaped inlet nozzle 6 into the outer cylinder 5, and then use tools to insert the retaining spring 52 into the outer cylinder 5 , and assembled to the inner annular slot of the outer cylinder 5, so that the I-shaped inlet water nozzle 6 is limitedly installed on the outer cylinder 5, and then the hollow insert 7 of the dielectric material is installed in the rectangular waveguide cylinder 1, and then the second can be rotated. A sleeve 23, because the first sleeve 23 is threadedly connected with the stud 24, so the rotation of the first sleeve 23 will make the stud 24 move left and right, and then drive the movable rectangular plate 8 to move along the inner wall of the rectangular waveguide 1 to suitable position, and then insert the movable rectangular plate 8 into the rectangular waveguide 1, so that the deployment column 9 is...

Abstract

The invention provides a waveguide short-size water load. The water load comprises a rectangular waveguide cylinder, the right end of the rectangular waveguide cylinder is provided with a rectangularcover and extends into the rectangular cover, the front end of the rectangular waveguide cylinder is fixedly connected with two outer cylinders, the front end of each outer cylinder is provided with an I-shaped inlet water nozzle, the I-shaped inlet water nozzle extends into each outer cylinder, . the front wall of the interior of the rectangular waveguide cylinder is slidably connected with two dielectric material hollow insertion columns, the dielectric material hollow insertion columns penetrate through the rectangular waveguide cylinder and are fixedly connected with I-shaped inlet water nozzles in the outer cylinders, the inner wall of the right side of the rectangular waveguide cylinder is slidably connected with a movable rectangular plate, and the middle of the left end of the movable rectangular plate is fixedly connected with a deploying column. Compared with the prior art, the water load has the following beneficial effects that: microwave power is absorbed by water, heat isdissipated through water cooling circulation, the microwave power is effectively absorbed, and the reflection power is reduced.

Description

technical field [0001] The invention relates to a waveguide short-dimension water load, which belongs to the technical field of waveguide feeders. Background technique [0002] In modern radar antenna equipment, the carrier of the link signal is mainly realized by the waveguide feeder, among which the waveguide load is widely used as the terminal equipment of the feeder link. Traditional high-power waveguide loads are mainly dry-type loads. The volume and weight of their products vary with the frequency, and the heat dissipation effect is not advantageous. The waveguide high-power water load of this product is a short-sized absorptive load with good heat dissipation. , high-power loads with light weight, ultra-short size and ultra-large power capacity are widely used in high-power microwave links. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a waveguide short-dimension water load to solv...
