This non-contact radar level gauge installation device offers advantages such as easy installation and removal between the non-contact radar level gauge body and the water storage barrel, and stable installation.
[0004] However, there are still some shortcomings in the above structure. During the installation or disassembly of the radar, it is necessary to synchronously control the four rods to be inserted into the four slots. Therefore, it is necessary to simultaneously control the four movable plates to control the movement of the four rods. As a result, it is not smooth for a single person to synchronously operate the four movable plates with both hands, and multiple people are required to assist and cooperate. Therefore, it is not easy to install the radar.
[0005] Therefore, it is necessary to provide a new non-contact radar level meter to solve the above technical problems. Utility Model Content

A rotating ring is rotatably installed above the positioning frame, and four arc grooves are opened on the rotating ring, which are adapted to the movable rod, and four control handles are fixedly installed on the rotating ring.
[0009] As a further solution of the present invention, four L-positioning rods are provided on the rotating ring, and a fixing bolt is fixedly installed on the L-positioning rod. One end of the fixing bolt extends into the rotating ring and is threadedly connected to the rotating ring. One end of the L-positioning rod is fixedly installed with a limiting slider, and an annular groove is provided on the positioning frame, and the limiting slider is adapted to the annular groove.
[0010] As a further solution of the present invention, a reflective plate is provided in the water storage barrel, and two connecting blocks are fixedly installed on the reflective plate. The two connecting blocks are symmetrically distributed, and two vertical guide rods are fixedly installed in the water storage barrel.

Then, after the mounting block is completely installed in the rectangular groove of the positioning frame, one end of the clamping block automatically snaps into the mounting hole on the mounting block to limit and fix it. In this way, the mounting block is firmly installed, which improves the installation convenience of the radar level meter body.
[0016] 2. After the rotating ring provided in the utility model is driven to rotate, the arc groove on the rotating ring can push the movable rod to make a linear radial movement.

The non-contact radar level gauge comprises: a water storage tank 1, on which a positioning frame 101 is fixedly mounted, a mounting block 102 disposed within a rectangular recess of the positioning frame 101, a radar level gauge body 103 fixedly mounted on the mounting block 102, four mounting holes disposed on the mounting block 102, and a snap mechanism disposed on the positioning frame 101;
[0024] The buckle mechanism includes four mounting slots 2, which are provided in the positioning frame 101. The positioning frame 101 is provided with four movable slots 201, which are communicated with the mounting slot 2. A clamping block 202 is slidably installed in the mounting slot 2, and the clamping block 202 is adapted to the mounting hole of the mounting block 102. A spring 203 is fixedly installed on one end of the clamping block 202, and one end of the spring 203 is fixedly connected to the inner wall of the mounting slot 2. A movable rod 204 is fixedly installed on the clamping block 202, and the movable rod 204 passes through the movable slot 201 and is slidably connected to the movable slot 201. A rotating ring 3 is rotatably installed above the positioning frame 101, and four arc grooves 301 are provided on the rotating ring 3, which are adapted to the movable rod 204, and four control handles 302 are fixedly installed on the rotating ring 3.
[0025] like Figure 4 As shown, four L-shaped positioning rods 4 are provided on the rotating ring 3, and fixing bolts 401 are threadedly installed on the L-shaped positioning rods 4. One end of the fixing bolt 401 extends into the rotating ring 3 and is threadedly connected to the rotating ring 3. One end of the L-shaped positioning rod 4 is fixedly installed with a limiting slider 402. An annular groove is formed on the positioning frame 101, and the limiting slider 402 is adapted to the annular groove.
[0026] After the L positioning rod 4 and the limiting slider 402 are provided, one end of the limiting slider 402 can be inserted into the annular groove, and then the L positioning rod 4 can be fixedly installed on the rotating ring 3. Therefore, when the rotating ring 3 is driven to rotate, the limiting slider 402 can prevent the rotating ring 3 from deflecting and falling off from the positioning frame 101, thereby improving the rotation stability of the rotating ring 3.
[0027] like Figure 2 As shown, a reflective plate 5 is provided in the water storage barrel 1, and two connecting blocks 501 are fixedly installed on the reflective plate 5. The two connecting blocks 501 are symmetrically distributed. Two vertical guide rods 502 are fixedly installed in the water storage barrel 1. The vertical guide rods 502 pass through the connecting blocks 501 and are slidably connected to the connecting blocks 501;
[0028] By providing the reflector 5 , after the radar electromagnetic wave is emitted onto the reflector 5 , the reflection distance from the path is short and vertical, which can improve the accuracy of liquid level measurement.
[0029] like Figure 3 As shown, the water storage barrel 1 is provided with four circular holes, in which springs 6 are fixedly installed, and one end of the spring 6 rests on the mounting block 102;
[0030] By providing the second spring 6, after the limiting effect of the mounting block 102 in the rectangular groove of the positioning frame 101 is released, the spring 2 6 is squeezed and the elastic force is released to push the mounting block 102 upward, thereby facilitating the removal of the mounting block 102 from the rectangular groove of the positioning frame 101.
[0031] like Figure 3 As shown, a sealing rubber ring 7 is fixedly installed on the water storage barrel 1, and the sealing rubber ring 7 is located in the rectangular groove of the positioning frame 101, and one side of the sealing rubber ring 7 is against the bottom of the mounting block 102;
[0032] By providing the sealing rubber ring 7 , after the mounting block 102 is completely installed in the rectangular groove of the positioning frame 101 , the surface of the sealing rubber ring 7 is pressed against the bottom of the mounting block 102 , thereby achieving a sealing effect.
[0033] like Figure 2 As shown, the bottom edge of the mounting block 102 is provided with a rounded edge, and the rounded edge is adapted to the arc-shaped end of the clamping block 202;
[0034] After the rounded edge is formed at the bottom of the mounting block 102 , when the bottom of the mounting block 102 abuts against the arc-shaped end of the clamping block 202 , the clamping block 202 can be moved away, thereby facilitating the rapid installation of the mounting block 102 into the rectangular groove of the positioning frame 101 .
[0035] The working principle of the non-contact radar level meter provided by this utility model is as follows:
[0036] Step 1: When installing the radar level gauge body 103, first place the mounting block 102 on the rectangular groove of the positioning frame 101, then gently press the mounting block 102 downward so that the mounting block 102 is completely inserted into the rectangular groove of the positioning frame 101. After the spring 1 203 is squeezed, the elastic force is released to press the block 202 to reset. Then, one end of the block 202 is inserted into the mounting hole on the mounting block 102, thereby limiting the mounting block 102, so that the radar level gauge body 103 is installed and fixed, thereby improving the installation convenience of the radar level gauge body 103.
[0037] The second step: When the radar level gauge body 103 needs to be disassembled, the control handle 302 can be held with one hand and rotated, and then the control handle 302 drives the rotating ring 3 to rotate, and then the arc groove 301 on the rotating ring 3 can push the movable rod 204 to make a linear radial movement, and then the movable rod 204 drives the clamping block 202 to move, so that the clamping block 202 moves toward the inside of the mounting groove 2, and then one end of the clamping block 202 will be moved out of the mounting hole on the mounting block 102, thereby releasing the limiting effect on the mounting block 102, and then the spring 2 6 releases the elastic force to push the mounting block 102 to move upward, thereby facilitating the quick removal of the mounting block 102 and improving the convenience of disassembling the radar level gauge body 103.
