Embodiment 1
[0022] Such as figure 1 As shown, the millimeter-wave height measuring device with anti-corrosion function of the present invention includes a millimeter-wave radar and a cuboid housing 1 for fixing the millimeter-wave radar. One side of the cuboid-shaped housing 1 is provided with a The opening 2 of the opening 2, the outer side of the opening 2 is provided with a curtain 3 covering the opening 2, the top of the curtain 3 is fixedly connected with the upper wall of the opening 2, and the inner wall of the rectangular parallelepiped housing 1 is provided with a plurality of horizontal telescopic rods 4. The side where the telescopic rod 4 is located is opposite to the side where the opening 2 is located. The movable end of the telescopic rod 4 is connected and fixed to the millimeter-wave radar. A triangular prism-shaped water guide cap 5 is connected above the rectangular parallelepiped housing 1. The quadrilateral shape of the water guide cap 5 The bottom surface is connecte...
Embodiment 2
[0025] Based on Embodiment 1, a plurality of first magnet pieces 6 are arranged on the side wall of the cuboid housing 1 where the opening 2 is located, and the first magnet pieces 6 are evenly distributed on the sides and sides of the side wall of the cuboid housing 1. On the bottom edge, the inner wall of the curtain 3 is provided with a second magnet piece corresponding to the first magnet piece 6 one by one. The first magnet piece and the second magnet piece are used to connect the cloth curtain and the housing. When the millimeter-wave radar is inside the housing, the stronger the connection between the cloth curtain and the housing, the better the sealing performance of the housing. The better the performance, the better the waterproof and dustproof performance; the connection between the first magnet piece and the second magnet piece will not affect the passage of the millimeter-wave radar through the opening.
Embodiment 3
[0027] Based on the above embodiment, a sump 7 is connected to the bottom of the cuboid housing 1, and a pH detector is arranged on the sump 7. The pH detector is used to detect the pH of rainwater, and the acid resistance of the shell can be improved according to the pH.
