Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

As shown in fig. 1 to 10, a radar device for dam body monitoring comprises a box body 1 and a radar host 2, wherein the radar host 2 is installed in the box body 1, the box body 1 is installed on the ground by means of supporting legs arranged at the bottom of the box body, two symmetrically-arranged extension plates 3 are integrally formed at the front end of the box body 1, and a baffle plate assembly 4 is installed between the two extension plates 3;

the baffle plate assembly 4 comprises a baffle plate body 41, a movable plate 42, a spring 43 and an end cover 44, wherein a vent hole 45 which is vertically arranged and penetrates through the whole baffle plate body 41 is arranged in the baffle plate body 41, an installation groove 46 communicated with the vent hole 45 is also arranged at the front end of the baffle plate body 41, the movable plate 42 is slidably connected in the installation groove 46, the front end of the installation groove 46 is sealed through the end cover 44, and the spring 43 is installed between the end cover 44 and the movable plate 42;

an ultrasonic transducer 47 connected to an ultrasonic generator 471 inside the radar main unit 2 is installed on the side surface of the extension plate 3, the transmitting end of the ultrasonic transducer 47 faces the vent 45, the ultrasonic transducers 47 are arranged on the extension plate 3 in a plurality of equal distances, a contact switch 48 for starting the ultrasonic generator 471 is further installed between the extension plate 42 and the end cover 44, and the contact switch 48 comprises a conductive plate 481 installed at the front end of the extension plate 42 and two contacts 482 installed at the rear end of the end cover 44.

In this embodiment, a cavity 49 is further provided inside the movable plate 42, a plurality of movable plastic balls 410 are provided in the cavity 49, the movable plate 42 can be designed into two symmetrical structures and assembled together in consideration of the assembly of the plastic balls 410, a connecting hole 411 communicated with the cavity 49 is provided on the side surface of the movable plate 42, and air inlet holes 412 matched with the connecting hole 411 are provided on the side surfaces of the extension plate 3 and the baffle body 41;

when the movable plate 42 is not pressed, the connection hole 411 is not communicated with the air inlet hole 412, and when the movable plate 42 is pressed to move towards the end cover 44, the connection hole 411 is communicated with the air inlet hole 412.

In this embodiment, the front end of the box 1 is provided with an opening, the baffle body 41 is connected with the opening by a sealing piece 413 and seals the opening, and the sealing piece 413 can be made of rubber or plastic.

In the present embodiment, in order to reduce the influence of the baffle plate assembly 4 on the radar wave signal, the baffle plate assembly 4 is made of glass fiber reinforced plastics or engineering plastics.

The working principle of deicing in the invention is as follows: when the freezing phenomenon occurs in the ventilation holes 45, the volume expansion occurs during the freezing process, and then the movable plate 42 is pressed, since the distance between the movable plate 42 and the end cap 44 is very small, typically 0.1-2mm, only a slight change in distance occurs, the contact switch 48 is turned on, the ultrasonic generator 471 is further activated to vibrate the ice adhered to the air vent 45 by the ultrasonic waves emitted from the ultrasonic transducer 47, thereby promoting the ice to be detached from the movable plate 42, and at the same time, since the movable plate 42 is displaced by the pressing of the ice, the air inlet 412 is communicated with the connecting hole 411, and considering that the wind speed is high at the position of the dam in the plateau area, the air flow enters the chamber 49 and blows the plastic balls 410 therein, so that the plastic balls 410 vibrate, further, the movable plate 42 will also generate a small vibration, which further accelerates the falling speed of the ice cubes. After the ice falls, the movable plate 42 is reset by the spring 43, the contact switch 48 is turned off, and the ultrasonic generator 471 stops working.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
