Example 1:
the present embodiment provides a waveguide assembly 100 for the transmission of microwaves. The waveguide assembly 100 includes a waveguide 110, a pin 130, and a cooling cavity 121; wherein, the wide side surface of the waveguide 110 is provided with a waveguide through hole, and the pin 130 can be inserted into the waveguide through hole in a sliding way; the cooling cavity 121 is disposed outside the waveguide 110 and covers the pin 130. Through letting in the coolant liquid for among the cooling chamber 121, can cool down round pin axle 130.
Specifically, the pin 130 is cylindrical and is in sealing engagement with the inner wall of the waveguide through hole via a sealing ring. The cooling cavity 121 is a rectangular tubular structure, one end of which is hermetically connected to the wall of the waveguide 110, and the other end of which is provided with a cover plate 123. The cover 123 is provided with a through hole of the cover 123, and the pin 130 is slidably disposed in the through hole of the cover 123. The cover plate 123, the cooling cavity 121, the pin 130 and the outer wall of the waveguide 110 enclose a relatively closed inner cavity. In other embodiments, the cooling cavity 121 may also be a cylindrical structure.
The pin 130 is provided with a water channel 132, a water inlet of which is arranged on the side wall of the pin 130, and a water outlet of which is arranged on the end surface of the outer end of the pin 130. The side wall of the cooling cavity 121 is provided with a water pipe port 1213, and after the water pipe port 1213 is connected with a cooling liquid pipe, the cooling liquid enters the inner cavity of the cooling cavity 121 through the water pipe port 1213, the cooling liquid firstly cools the surface of the pin 130, then enters the water flow channel 132 through the water inlet of the water flow channel 132, cools the inside of the pin 130, and finally flows into the water outlet pipe through the water outlet of the cooling channel. The design enables the outer surface and the inner surface of the pin shaft 130 to be cooled, so that the pin shaft 130 can be effectively cooled integrally, and the working stability of the waveguide assembly 100 can be ensured.
In order to fix the pin 130 at a predetermined position, it is prevented from moving under the vibration; a threaded hole is formed in the side wall of the cooling cavity 121, a locking screw 150 is arranged in the threaded hole, and the inner end of the locking screw 150 abuts against the side wall of the pin shaft 130. When the pin 130 needs to be moved, the locking screw 150 is loosened. In other embodiments, the locking screw 150 may not be provided, and the pin 130 may be fixed by using the friction between the pin 130 and the inner wall of the through hole of the cover plate 123 or the waveguide through hole.
Example 2:
the present embodiment provides another waveguide assembly 100, which is different from embodiment 1 mainly in that a partition plate 122 is disposed in the cooling cavity 121, a water inlet and a water outlet of the water flow channel 132 of the pin 130 are disposed in the cooling cavity 121, and two water pipe joints 1213 are disposed on the side wall of the cooling cavity 121.
Specifically, the partition plate 122 is a rectangular plate which is disposed in parallel with the cover plate 123 at a distance, and is located approximately at the middle of the cooling cavity 121. A partition through hole is formed in the middle of the partition 122, and the pin 130 passes through the partition 122 through hole. The partition 122 separates the inner cavity of the cooling cavity 121 into two relatively independent cavities, one is referred to as an inlet cavity 1211 and the other is referred to as an outlet cavity 1212 for convenience of description. The side wall of the cooling cavity 121 is provided with two water pipe interfaces 1213, and the two water pipe interfaces 1213 are respectively arranged on the outer walls of the water inlet 1211 and the water outlet 1212; the two water pipe joints 1213 are connected to a water inlet pipe and a water outlet pipe, respectively.
The water inlet and the water outlet of the water flow channel 132 of the pin 130 are respectively located in the water inlet 1211 and the water outlet 1212, and after the cooling liquid enters the water inlet 1211 through the water pipe connection 1213, the cooling liquid cools the outer surface of the pin 130 on the one hand, enters the water flow channel 132 on the other hand, enters the water outlet 1212 through the water outlet of the water flow channel 132, and finally flows out through the water outlet. In this embodiment, the water inlet pipe and the water outlet pipe are both connected to the cooling cavity 121, and the connection stability is good.
Further, the pin 130 is further provided with a limiting member 160, and the limiting member 160 is used for limiting a first limit position and a second limit position of the pin 130, where the two limit positions correspond to a lower limit position and an upper limit position in the drawing. When the pin 130 moves towards the direction close to the waveguide 110, the limiting member 160 can abut against the outer wall of the waveguide 110, and at this time, the length H1 of the pin 130 extending into the waveguide 110 is 1/2 of the height H2 of the inner cavity of the waveguide 110; when the pin 130 moves in the opposite direction, the limiting member 160 can abut against the partition 122, and the inner end of the pin 130 is flush with the inner surface of the waveguide 110.
If the pin 130 extends into the waveguide 110 by a length H1 that exceeds 1/2 of the height H2 of the cavity of the waveguide 110, it may cause the waveguide 110 to malfunction, and if the inner end of the pin 130 is lower than the inner surface of the waveguide 110, the inner surface of the waveguide 110 may form a recess, which may also affect the proper operation of the waveguide 110. Therefore, the positioning of the position-limiting member 160 can provide a guarantee for the waveguide 110 to operate normally.
In order to fix the pin 130 at a predetermined position and facilitate the driving of the pin 130 to move, the waveguide assembly 100 is further provided with a connector 141 and a mounting plate 142, and the mounting plate 142 is connected to the cooling chamber 121 through the connector 141. The mounting plate 142 and the cover plate 123 are arranged in parallel at intervals, a threaded rod 143 is arranged on the mounting plate 142, and the end of the threaded rod 143 is rotatably connected with the outer end of the pin 130. When the threaded rod 143 is rotated, it can move the pin 130 along its axial direction.
In other embodiments, the mounting plate 142 and the threaded rod 143 may not be provided, and as shown in fig. 3, a locking screw 150 may be directly provided on a sidewall of the cooling cavity 121 to lock the pin 130.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
