Description

Technical Field

[0001] The utility model relates to the technical field of waveguide switches, in particular to a high-power waveguide switch used for single- and double-path switching. Background Art

[0002] Waveguide switch is one of the commonly used waveguide components in microwave systems, and is mainly used for switching microwave energy transmission channels. From the perspective of waveguide switch structure, waveguide switch generally includes a rotor and a stator, each of which is provided with a waveguide link channel. By rotating the rotor to connect the corresponding waveguide link, the microwave transmission channel is switched. Therefore, the waveguide switch has high requirements for the positioning accuracy of the rotor and stator.

[0003] In the case of high-power microwave energy transmission, in order to avoid sparking and breakdown inside the waveguide switch, the waveguide switch needs to be filled with N2 or SF6 gas at a certain pressure to increase the power capacity of the device. Therefore, high-power waveguide switches also have high airtightness requirements.

[0004] In order to pursue the output of higher-power microwave energy, the existing technology has also developed the power synthesis of two high-power microwave sources in a narrow band, so as to obtain a larger external radiation power. Users can choose the corresponding power output mode according to the actual usage scenario, that is, the single-channel output mode and the dual-channel power synthesis output mode. For this application scenario, the current technology can only be achieved by replacing the power synthesizer and the single-channel working waveguide section, which is extremely inconvenient in operation. Therefore, when pursuing higher-power microwave energy output, it is an urgent problem to require the waveguide switch to realize the convenient switching between the single-channel output and the dual-channel synthesis of the microwave source.

[0005] In summary, when applied to high-power microwave energy transmission, the waveguide switch cannot directly switch the working mode between single-channel microwave output and dual-channel synthesis, resulting in complex switching operations and low working efficiency. Utility Model Content

[0006] In view of the problems raised by the above-mentioned background technology, the purpose of the present utility model is to provide a high-power waveguide switch for single-channel and dual-channel switching, which solves the problem that the existing waveguide switch cannot directly perform industrial mode switching between single-channel microwave output and dual-channel synthesis when used in high-power microwave energy transmission, resulting in complicated switching operation and low working efficiency.

When the dual-channel working channels in the waveguide switching channel correspond to the transmission channels, the rotor is pressed down through the operating handle to press the dual-channel working channels in the waveguide switching channel into the positioning step, thereby realizing dual-channel microwave source output.

[0014] The rotor is operated through the operating handle, so that the waveguide switching channel set on the rotor cooperates with the stator and the transmission channel to complete the single-way and double-way switching.

The schematic implementation mode of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0040] Example 1

[0041] Figure 1 The overall structure explosion diagram of the high-power waveguide switch for single-way and double-way switching provided in Example 1 of the utility model is as follows: Figure 1 As shown, a high-power waveguide switch for single-way and double-way switching operation includes:

[0042] The stator 1 is a cubic structure, the top surface of the stator 1 is inwardly recessed to form a circular concave platform, and the circular concave platform is used to place the rotor 2; three waveguide installation openings 101 are respectively provided on the three side elevations of the stator 1, and the waveguide installation openings 101 are used to install the transmission waveguide 3 to form a waveguide transmission channel; the circular concave platform is provided with a positioning step 103 near the waveguide installation opening 101;

[0043] A waveguide switching channel 202 is provided on the side of the rotor 2 facing the circular concave platform, and the waveguide switching channel 202 includes a single-channel working channel for single-channel microwave source output and a dual-channel working channel for dual-channel microwave source power synthesis output; an operating handle 5 is installed on the side of the rotor 2 facing away from the circular concave platform, and the operating handle 5 is used to rotate the rotor 2 to switch between single and dual channels.

[0044] It should be noted that if Figure 2 As shown, three waveguide installation ports 101 are respectively arranged on the three side elevations of the stator 1, and each waveguide installation port 101 and a transmission waveguide 3 form a waveguide transmission channel, forming a total of three waveguide transmission channels, wherein the waveguide transmission channel includes two input channels and one output channel. As shown in FIG5(b), a waveguide switching channel 202 is designed on the back of the rotor 22, and the waveguide switching channel 202 includes two microwave transmission channels, one for the output of a single microwave source, and the other for the power synthesis output of two microwave sources. The internal structures of the two channels are independent of each other and completely isolated. The dual-channel working channel is T-shaped, including a dual-channel output channel and two dual-channel synthesis channels, the two dual-channel synthesis channels are respectively connected to the input port in the waveguide transmission channel, and a dual-channel output channel is connected to the output port in the waveguide transmission channel; the single-channel working channel includes two single-channel working channels, and the two single-channel working channels are respectively connected to the input port and the output port in the waveguide transmission channel.

[0045] When a single-channel microwave source output is required, the rotor 2 is lifted to a certain height by the operating handle 5 so that the waveguide switching channel 202 exits the positioning step 103, and then the operating handle 5 is rotated. When the single-channel working channel in the waveguide switching channel 202 corresponds to the transmission channel, the rotor 2 is pressed downward by the operating handle 5 to press the single-channel working channel in the waveguide switching channel 202 into the positioning step 103, so that the single-channel microwave source output can be achieved.

[0046] When dual-path microwave source output is required, the rotor 2 is lifted to a certain height by the operating handle 5 so that the waveguide switching channel 202 exits the positioning step 103, and then the operating handle 5 is rotated. When the dual-path working channels in the waveguide switching channel 202 correspond to the transmission channels, the rotor 2 is pressed downward by the operating handle 5 to press the dual-path working channels in the waveguide switching channel 202 into the positioning step 103, thereby realizing dual-path microwave source output.

[0047] The rotor 2 is operated by the operating handle 5, so that the waveguide switching channel 202 arranged on the rotor 2 cooperates with the stator 1 and the transmission channel to complete the single-way and double-way switching. The above operation process does not require changing the microwave transmission link. The waveguide switch working mode can be switched by simply turning the operating handle 5, which is convenient and quick to operate.

[0048] In an optional embodiment, the rotor 2 is a cylindrical structure, the diameter of the circular concave platform is larger than the diameter of the rotor 2 , there is a clearance fit between the circular concave platform and the rotor 2 , and the depth of the circular concave platform is larger than the thickness of the rotor 2 .

[0049] In this embodiment, the depth of the circular concave platform is slightly greater than the thickness of the rotor 2 .

[0050] It should be noted that, refer to Figure 4 In order to make the rotor 2 rotate smoothly when being lifted up and rotated, the diameter of the circular concave platform is matched with the diameter of the rotor 2, and the depth of the circular concave platform is made greater than the thickness of the rotor 2.

[0051] In an optional embodiment, a pin hole 102 is provided at the center of the circular recess, and a pin shaft 201 for use with the pin hole 102 is provided on the side of the waveguide switching channel 202 facing the circular recess, the diameter of the pin hole 102 is larger than the diameter of the pin shaft 201, and there is a clearance fit between the pin hole 102 and the pin shaft 201, and the depth of the pin hole 102 is greater than the length of the pin shaft 201.

[0052] In this embodiment, the diameter of the pin hole 102 is slightly larger than the diameter of the pin shaft 201 .

[0053] It should be noted that, referring to Figure 5(a), a pin shaft 201 for use with the pin hole 102 is provided on the side of the waveguide switching channel 202 facing the circular recess. The setting of the pin hole 102 and the pin shaft 201 can ensure that the pin shaft 201 is still in the pin hole 102 after the rotor 2 is lifted upward. At the same time, it can ensure that the rotor 2 can rotate around the central axis without deflection after being lifted upward.

[0054] In an optional embodiment, a side of the positioning step 103 facing the rotor 2 is a chamfered structure.

[0055] It should be noted that the height dimension of the positioning step 103 is smaller than the height dimension of the rotor 2 that can be lifted upward, and the side of the positioning step 103 facing the rotor 2 is designed to be a chamfered structure. When the rotor 2 is rotated into place and pressed downward into the positioning step 103, the chamfered structure plays a guiding role, so that the waveguide switching channel 202 on the rotor 2 is accurately docked with the transmission waveguide 3.

[0056] In an optional embodiment, the waveguide opening surface 301 of the waveguide switching channel 202 is a 45° inclined waveguide surface, the waveguide opening surface 301 on the inner side of the transmission waveguide 3 is a 45° inclined waveguide opening surface 301, and the 45° inclined waveguide surface matches the 45° inclined waveguide opening surface 301.

[0057] It should be noted that, refer to Figure 6The waveguide opening of the propagation waveguide is a standard rectangular waveguide, with a standard rectangular waveguide flange for the outside and a 45° waveguide opening surface 301 for the inside, whose size matches the 45° waveguide opening surface 301 of the waveguide switching channel 202 on the rotor 2. The beneficial effect of adopting this structure is that when the rotor 2 is rotated into place for matching and docking, the 45° waveguide opening surface 301 between the two is closely contacted and compressed by the pressure of the external pressure plate, so that the airtightness of the microwave transmission link is realized. Therefore, when high-power microwave energy is transmitted, N2 or SF6 gas of a certain pressure can be filled in the microwave transmission link to improve the power capacity of the device.

[0058] In an optional embodiment, the 45° inclined waveguide opening surface 301 is provided with a sealing groove 302, and the sealing groove 302 is used for placing a sealing strip.

[0059] It should be noted that when the rotor 2 is rotated into place, the two are in close contact and the sealing strip is compressed under the pressure of the external pressure plate, so that the airtightness of the microwave transmission link inside the waveguide switch is achieved. At the same time, the waveguide switching channel 202 on the rotor 2 and the output waveguide adopt a 45° inclined waveguide surface 301 structure, and under the pressure of the external pressure plate, the airtightness of the microwave transmission link inside the waveguide switch is achieved. Therefore, the entire microwave transmission link can be inflated, thereby achieving the transmission of higher-power microwave energy.

[0060] In an optional embodiment, a microwave transmission channel path diagram is designed on a side of the operating handle 5 facing away from the rotor 2 , and the microwave transmission channel path diagram includes a mark 501 , and the mark 501 corresponds to the waveguide switching channel 202 .

[0061] It should be noted that, referring to Figure 7(a), a microwave transmission channel path diagram is designed on the front of the operating handle 5, and is engraved with the logos 501 of "power synthesis" and "single-channel output", and the logos 501 correspond to the waveguide switching channel 202 of the rotor 2. The microwave transmission channel path diagram can reflect the relative position of the current waveguide switching channel 202 and the stator 1.

[0062] In an optional embodiment, a mounting shaft is provided on a side of the operating handle 5 facing the rotor 2 , and the mounting shaft is used to cooperate with a mounting hole on the rotor 2 to achieve a fixed connection between the operating handle 5 and the rotor 2 .

[0063] It should be noted that, referring to FIG. 7( b ), a mounting shaft is designed on the back of the operating handle 5 , and the mounting shaft cooperates with the mounting hole on the rotor 2 to achieve a fixed connection between the operating handle 5 and the rotor 2 , and the rotor 2 can be rotated by rotating the operating handle 5 .

[0064] In an optional embodiment, the high-power waveguide switch further includes a cover plate 4 and a pressure plate, and the cover plate 4 is provided with a plurality of outer mounting holes and a plurality of inner mounting holes, the outer mounting holes are used to connect the cover plate 4 and the stator 1, and the inner mounting holes are used to install the pressure plate.

[0065] In an optional embodiment, the pressure plate is an L-shaped structure, with an oblong hole at one end and a step at the other end. The pressure plate is connected to the cover plate 4 by passing a butterfly screw through the inner mounting hole and the oblong hole, and the step is used to tighten the operating handle 5.

[0066] It should be noted that, refer to Figure 1 and Figure 8 The cover plate 4 is a thin plate structure with a series of mounting holes. The mounting holes around the cover plate 4 can be used to connect the cover plate 4 with the stator 1, and the four mounting holes on the inner side can be used to install the pressure plate. The pressure plate structure is L-shaped, with an oblong hole at one end, through which a butterfly screw can pass to connect the pressure plate with the cover plate 4; a step is provided at the other end, which can be used to tighten the operating handle 5 to achieve a close fit between the rotor 2 switching channel and the output waveguide.

[0067] The working state of the utility model is realized as follows:

[0068] refer to Figure 2 When the two-way microwave source "power synthesis" output is required, first loosen the butterfly screw, withdraw the pressure plate backwards, lift the rotor 2 upward to a certain height through the operating handle 5, so that the waveguide switching channel 202 withdraws from the positioning step 103, and then turn the operating handle 5 by observing the mark 501. When the "power synthesis" path diagram corresponds to the output waveguide, press the rotor 2 downward through the operating handle 5 to press the dual-way synthesis channel of the waveguide switching channel 202 into the positioning step 103. Finally, press the operating handle 5 with the pressure plate and tighten the butterfly screw.

[0069] Referring to FIG. 3 and FIG. 3( b ), when single-channel microwave source output is required, the operating handle 5 is turned in the same manner as described above, and the mark 501 is observed. When the “single-channel operation” path diagram corresponds to the output waveguide, the rotor 2 is pressed downward by the operating handle 5 to press the single-channel operation channel of the waveguide switching channel 202 into the positioning step 103. Finally, the pressure plate is pressed against the operating handle 5, and the butterfly screw is tightened.

[0070] The above operation process does not require changing the microwave transmission link, and the waveguide switch working mode can be switched by simply rotating the operating handle 5, which is convenient and quick to operate.
