[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1-3A radar level gauge that is easy to maintain is shown, comprising a radar level gauge 1, a fixing seat 3 is arranged on the back of the radar level gauge 1, a fixing plate 2 is sleeved on the middle part of the radar level gauge 1, a connecting seat 4 is fixedly connected to the front of the fixing seat 3, a connecting groove 5 for limiting the moving direction of the fixing plate 2 is provided on the front of the connecting seat 4, a limiting groove 6 is symmetrically provided horizontally and longitudinally on the top of the fixing plate 2, a limiting block 7 for limiting the fixing plate 2 from moving out of the connecting groove 5 is inserted and connected inside the limiting groove 6, and a moving part for moving the position of the limiting block 7 is provided on the top of the limiting block 7.

[0019] It should be noted that the radar level meter 1 is a radar level meter of model HBRD-FMF11. When in use, the radar level meter 1 is first fixed at the desired position, and then the water level is determined by sending and receiving signals; the fixed plate 2 is sleeved on the middle of the radar level meter 1, and the fixed plate 2 is fixed to the middle of the radar level meter 1 by nuts, and circular holes are provided at the four corners of the fixed seat 3. When the position of the fixed seat 3 needs to be fixed, bolts are passed through the circular holes on the fixed seat 3, and the end threads of the bolts are inserted and connected to the desired fixed position, and the position of the fixed seat 3 is fixed by bolts. The connecting seat 4 is fixedly connected to the front side of the fixing seat 3 by welding, and the front side of the connecting seat 4 is fixed. A connecting groove 5 matched with the fixing plate 2 is provided on the surface, which is used to insert the side of the fixing plate 2 with the limiting groove 6 into the interior of the connecting groove 5 when in use; the limited groove 6 is matched with the set limiting block 7, which is used to insert the limiting block 7 into the interior of the limiting groove 6 when in use. When in use, one side of the fixing plate 2 is first inserted into the interior of the connecting groove 5, so that the moving direction of the fixing plate 2 is along the direction of the connection groove 5. When one side of the fixing plate 2 is inserted into the interior of the connecting groove 5, the limiting block 7 is driven by the moving part to move into the interior of the limiting groove 6. The limiting block 7 is blocked by the fixing plate 2 so that the fixing plate 2 cannot move out of the connecting groove 5, thereby fixing the position of the fixing plate 2, and fixing the position of the radar level meter 1 through the fixing plate 2.

[0020] Specifically, the fixing plate 2 is inserted and connected inside the connecting groove 5 , and two ends of the limiting block 7 are inserted and connected to the inner walls of the top end and the bottom end of the connecting groove 5 respectively.

[0021] Furthermore, when the radar level gauge 1 needs to be disassembled for maintenance, the limit block 7 is driven by the movable part to move out of the limit groove 6 opened on the fixed plate 2, and then the fixed plate 2 is taken out from the connecting groove 5, so that the fixed plate 2 and the radar level gauge 1 are disassembled.

[0022] Specifically, a cavity 8 is opened at the top of the connecting seat 4, and the moving part includes a moving plate 9 inserted and connected inside the cavity 8, the limit block 7 is fixedly connected to the bottom end of the moving plate 9, and a pushing part and a pulling part are arranged on the top of the moving plate 9.

[0023] Furthermore, when it is necessary to fix one side of the fixed plate 2 in the connecting groove 5, first pull the movable plate 9 upward through the lifting portion 1, and drive the bottom end of the limit block 7 to move out of the connecting groove 5 through the movable plate 9, and then insert the side of the fixed plate 2 with the limit groove 6 into the interior of the connecting groove 5. When the limit groove 6 on the fixed plate 2 is aligned with the limit block 7, the movable plate 9 is driven to move to one side of the fixed plate 2 through the pushing portion, and the limit block 7 is driven to move into the interior of the limit groove 6 through the movable plate 9.

[0024] Specifically, the pushing part includes a spring 10 arranged on the top of the moving plate 9 , and the spring 10 is inserted and connected inside the cavity 8 .

[0025] It should be noted that one end of the spring 10 is fixedly connected to the top of the movable plate 9, and the other end is fixedly connected to the inner wall of the top of the cavity 8. The spring 10 has a deformable characteristic. When the spring 10 is squeezed by the movable plate 9 during use, the spring 10 is deformed. When the spring 10 loses the squeezing force of the movable plate 9, the spring 10 restores the deformation and drives the movable plate 9 to move to the side away from the spring 10 through the push of the spring 10.

[0026] Specifically, the lifting part includes a connecting rod 11 fixedly connected to the top of the movable plate 9, the connecting rod 11 is inserted and connected to the middle of the spring 10, and a handle 12 is provided at the top of the connecting seat 4, the handle 12 is fixedly connected to the top of the connecting rod 11, and an insertion hole 13 is opened in the middle of the handle 12.

[0027] Furthermore, when it is necessary to move the limit block 7 upward, the staff inserts a finger into the insertion hole 13, pulls the handle 12 upward with the finger, drives the connecting rod 11 and the movable plate 9 upward through the handle 12, and drives the limit block 7 to move through the movable plate 9.

[0028] Specifically, guide rods 14 for limiting the moving direction of the moving plate 9 are symmetrically interlaced on both sides of the moving plate 9 , and both ends of the guide rods 14 are fixedly connected to the inner walls of the top and bottom ends of the cavity 8 .

[0029] It should be noted that there are at least two guide rods 14, which are fixedly connected to the inside of the cavity 8. When the movable plate 9 moves inside the cavity 8, the movable plate 9 slides in the middle of the guide rods 14. Through the design of at least two guide rods 14, the two sides of the movable plate 9 are restricted to prevent the movable plate 9 from shaking inside the cavity 8.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
