In this embodiment, a first leveling nut 411 is disposed on one side of the mounting portion 41, the first leveling component is a first leveling bolt 9 having one end sequentially penetrating through the first leveling nut 411 and the mounting portion 41 and then abutting against the borehole wall, and when one end of the first leveling bolt 9 penetrates through the first leveling nut 411, the first leveling bolt is screwed with the first leveling nut 411, and the specific effects are shown in fig. 3 and fig. 4. The first leveling nut 411 is arranged on one side of the installation part 41, when the support is installed on an uneven well wall, one end of the first leveling bolt 9 penetrates through the first leveling nut 411 and the installation part 41 in sequence and then abuts against the well wall, because the first leveling bolt 9 is provided with an external thread matched with the first leveling nut 411, when the first leveling bolt 9 is rotated, the length of the first leveling bolt 9 penetrating through the installation part 41 is changed, so that the inclination angle of the installation part 41 and the well wall is adjusted until the installation part 41 is in a vertical state in the inspection well 1, and then the installation part 41 is fixedly connected with the well wall through the installation part, so that the installation part 41 is prevented from inclining due to the uneven well wall, the ultrasonic liquid level meter 6 is prevented from inclining, and the perpendicularity with the liquid level in the inspection well 1 cannot be guaranteed.

In this embodiment, the mounting portion 41 is provided with a rotating shaft 412, one end of the main arm 51 is rotatably connected to the rotating shaft 412 in the vertical direction, and a second leveling component is further included to adjust the rotation angle of the main arm 51 in the vertical direction of the rotating shaft 412, as shown in fig. 3 and 4. The mounting portion 41 is provided with a rotating shaft 412, and one end of the main arm 51 is connected to the rotating shaft 412 so as to be rotatable in the vertical direction of the mounting portion 41 around the rotating shaft 412, so that the inclination angle of the ultrasonic level gauge 6 on the extension arm 52 in the inspection well 1 changes as the inclination angle of the main arm 51 in the vertical direction of the mounting portion 41 changes.

The main arm 51 is rotatably connected to the mounting portion 41 via the rotating shaft 412, and a second leveling unit is provided to adjust the rotation angle of the main arm 51 in the vertical direction of the mounting portion 41, so that the ultrasonic level gauge 6 on the extension arm 52 is leveled in the inspection well 1. The second leveling component is also provided for preventing the shaft wall from being uneven, so that when the mounting part 41 is fixedly connected with the shaft wall in parallel through the mounting part, the mounting part 41 cannot be kept in a vertical state in the inspection well 1, and the ultrasonic liquid level meter 6 on the lengthened arm 52 is also inclined in the inspection well 1.

In the present application, the main arm 51 is rotatably connected to the mounting portion 41, when the mounting portion 41 cannot maintain a vertical state in the inspection well 1, the second leveling component drives the main arm 51 to rotate in the vertical direction of the mounting portion 41, so that the main arm 51 and the mounting portion 41 no longer maintain a horizontal connection state, and the inclination angle between the main arm 51 and the mounting portion 41 changes until the ultrasonic liquid level meter 6 on the extension arm 52 is perpendicular to the liquid level in the inspection well 1. The ultrasonic level gauge 6 is leveled by a second leveling assembly. The support can be suitable for installation in harsh environments, the practicability of the support is improved, and the application range of the support is enlarged.

In this embodiment, the main arm 51 is provided with a second leveling nut 512, and the second leveling component is a second leveling bolt 10 having one end sequentially penetrating through the second leveling nut 512 and the main arm 51 and abutting against the supporting portion 42, which has the specific effect shown in fig. 3 and 5. The main arm 51 is provided with a second leveling nut 512, the second leveling bolt 10 sequentially penetrates through the second leveling nut 512 and the main arm 51 from above the main arm 51 and then is abutted against the supporting part 42, and because the second leveling bolt 10 is also provided with an external thread matched with the second leveling nut 512, when the second leveling bolt 10 is rotated, the length of the second leveling bolt 10 penetrating through the main arm 51 is changed, so that the main arm 51 is driven to rotate in the vertical direction of the mounting part 41 by taking the rotating shaft 412 as the center of a circle, the rotating angle of the main arm 51 in the vertical direction of the mounting part 41 is adjusted, and the ultrasonic liquid level meter 6 is ensured to be vertical to the liquid level in the inspection well 1.

In the present application, the first leveling component and the second leveling component can be used independently or cooperatively. Because the first leveling component is leveled by the first leveling bolt 9 penetrating through the first leveling nut 411 and then abutting against the well wall, in the leveling process, the mounting part 41 is inclined on the well wall, and the first leveling bolt 9 is perpendicular to the mounting part 41, when the inclination angle of the mounting part 41 on the well wall is gradually increased, the abutting area of the end part of the first leveling bolt 9 and the well wall is gradually reduced, and therefore, the adjusting range of the first leveling component is smaller. Similarly, the adjustment range of the second leveling component is smaller.

When the inclination angle of the well wall is smaller and only small-range adjustment is needed, one of the first leveling component and the second leveling component can be selected at will for leveling; when the inclination of the wall of a well is great, adopt first leveling subassembly to carry out the leveling earlier when the support installation, adopt the second leveling subassembly to carry out the leveling again to make this support also can install in the relatively poor inspection shaft 1 of roughness, further improve the practicality of this support, increase the application scope of this support.

In this embodiment, the main arm 51 is provided with a second strip-shaped hole 511, the supporting portion 42 is provided with a locking nut 421, and the main arm further includes a locking bolt 12, one end of which penetrates through the second strip-shaped hole 511 and is screwed with the locking nut 421, as shown in fig. 3, 4 and 5. Since the second leveling bolt 10 abuts against the supporting portion 42 and is not fixedly connected to the supporting portion 42, when the second leveling bolt 10 is not rotated, the main arm 51 cannot rotate downward but can rotate upward under the action of external force, and the main arm 51 fluctuates under the flush of water flow in the inspection well 1, which affects the detection result of the ultrasonic liquid level meter 6.

Therefore, in the present application, the main arm 51 is provided with a second strip-shaped hole 511, the support portion 42 is provided with a lock nut 421, and one end of the lock bolt 12 penetrates through the second strip-shaped hole 511 and then is screwed with the lock nut 421. When the second leveling bolt 10 needs to be rotated to adjust the inclination angle of the main arm 51 in the vertical direction of the mounting part 41, the locking bolt 12 is loosened and does not abut against the top of the main arm 51, so that the main arm 51 can be rotated in the vertical direction of the mounting part 41 to level the ultrasonic liquid level meter 6; after the ultrasonic level meter 6 is perpendicular to the liquid level in the inspection well 1, the lock nut 421 is tightened to make the nut of the lock nut 421 abut against the top of the main arm 51, so that the main arm 51 is limited at the upper part, the main arm 51 is kept at the inclination angle with the mounting part 41, and the main arm 51 is prevented from fluctuating under the washing of water flow to affect the detection result of the ultrasonic level meter 6.
