[0024] The outer surface of the toothed plate 203 is meshed with a gear 207, and two rotating shafts 210 and a guided wave radar level meter 212 are respectively arranged below the rotating plate 202. The inner wall of the first rectangular plate 208 is rotatably connected to the outer surface of one of the rotating shafts 210, and two limit grooves 9 are provided on the back of the rotating plate 202. The interior of each limit groove 9 is slidably connected to a limit block 11, and the bottom surfaces of the two limit blocks 11 are fixedly connected to a second rectangular plate 209. By providing the limit grooves 9 and the limit blocks 11, the limit blocks 11 can slide inside the limit grooves 9, and the second rectangular plate 209 can be indirectly installed below the rotating plate 202.

[0025] One end of one of the rotating shafts 210 close to the gear 207 is fixedly connected to the back side of the gear 207, and the inner wall of the second rectangular plate 209 is rotatably connected to the outer surface of the other rotating shaft 210.

[0027] The working principle of the utility model is as follows: when in use, firstly, the stepper motor 201, the hydraulic rod 205 and the guided wave radar level meter 212 are connected to the power supply respectively.

Then, the stepper motor 201 is operated to drive the rotating plate 202 fixed at the output end of the stepper motor 201 to rotate, thereby driving the device connected below the rotating plate 202 to rotate synchronously. In conjunction with the operation of the hydraulic rod 205, the transmission plate 206 and the toothed plate 203 fixed on the upper surface of the transmission plate 206 can be pushed downward by the operation of the hydraulic rod 205. There is a meshing connection relationship between the outer surface of the toothed plate 203 and the gear 207, so the hydraulic rod 20 Pushing downward will eventually drive the gear 207 to rotate, and the back of the gear 207 is connected to one end of one of the rotating shafts 210. Therefore, the rotation of the gear 207 will transmit the rotational power to the guided wave radar level meter 212 through the rotating shaft 210, which can drive the guided wave radar level meter 212 to rotate. The restriction on the second rectangular plate 209 can be canceled by rotating the limiting plate 12, and then the limiting block 11 can be pulled out from the inside of the limiting groove 9, so that the guided wave radar level meter 212 limited between the two limiting plates 211 can be removed to complete the disassembly, thereby ensuring that the guided wave radar level meter 212 can freely adjust the angle when in use, and ensuring that the installation position of the guided wave radar level meter 212 will not be subject to excessive restrictions due to the detection angle.
