[0023] The present utility model will be further described below in conjunction with the accompanying drawings:

[0024] As Figure 1 - Figure 4 shown, a fixing device for an environmental detector includes a main shaft 100, and an angle adjustment mechanism is provided on the outer side of the main shaft 100. The angle adjustment mechanism includes inner clamping plate assemblies symmetrically distributed. The inner clamping plate assembly includes an inner clamping plate 201. The inner clamping plate 201 is rotatably connected to the main shaft 100. A U-shaped plate 202 is fixedly connected to the side surface of the inner clamping plate 201. A threaded sleeve 203 is provided inside the U-shaped plate 202. Rotating shafts 204 are fixedly connected to the upper and lower sides of the threaded sleeve 203. The rotating shafts 204 are rotatably connected to the U-shaped plate 202. A bidirectional threaded rod 205 is provided between the inner clamping plate assemblies. The two ends of the bidirectional threaded rod 205 are threadedly connected to the threaded sleeve 203. A handle one 206 is fixedly connected to the middle of the bidirectional threaded rod 205. Clamping mechanisms symmetrically distributed are provided on the side of the inner clamping plate 201 away from the angle adjustment mechanism. A locking mechanism is provided on the outer side of the main shaft 100.

[0025] When manually rotating the handle 206 of the first one, it drives the double-threaded rod 205 to rotate, causing the threaded sleeves 203 to approach or move away from each other. The threaded sleeves 203 are movably connected to the U-shaped plate 202 through the rotating shafts 204, thereby adjusting the distance between the U-shaped plates 202, and finally adjusting the angle of the inner clamping plate 201, so that it can be fitted and installed at the turning points of the retaining walls at different angles.

[0026] The clamping mechanism includes an L-shaped plate 301. One end of the L-shaped plate 301 is fixedly connected to the inner clamping plate 201. The bottom side of the horizontal plate of the L-shaped plate 301 is slidably connected with an outer clamping plate 302. A threaded component is provided on the vertical plate of the L-shaped plate 301.

[0027] The L-shaped plate 301 is used for slidably connecting the outer clamping plate 302 and installing the threaded component. The threaded component pushes the outer clamping plate 302 close to the inner clamping plate 201 to form clamping.

[0028] The threaded component includes a clamping threaded rod 303. The clamping threaded rod 303 is threadedly connected to the vertical plate of the L-shaped plate 301. One end of the clamping threaded rod 303 is rotatably connected to the outer clamping plate 302. The other end of the clamping threaded rod 303 is fixedly connected with a handle 304 of the second one.

[0029] When manually rotating the handle 304 of the second one, it drives the clamping threaded rod 303 to rotate, causing the clamping threaded rod 303 to push the outer clamping plate 302 close to the inner clamping plate 201.

[0030] The locking mechanism includes two arc-shaped clamping plates 401. One end of the arc-shaped clamping plates 401 is hinged to each other. The other end of the arc-shaped clamping plates 401 is fixedly connected with a side plate 402. A locking threaded rod 403 is threadedly connected to the side plate 402 on one side. The locking threaded rod 403 is rotatably connected to the other side plate 402. One end of the locking threaded rod 403 is fixedly connected with a handle 404 of the third one.

[0031] When manually rotating the handle 404 of the third one, it drives the locking threaded rod 403 to rotate, causing the side plates 402 to approach each other, and finally causing the arc-shaped clamping plates 401 to fasten the main shaft 100.

[0032] The locking mechanism further includes a connecting plate 405. The connecting plate 405 is fixedly connected to the outside of the arc-shaped clamping plates 401. One end of the connecting plate 405 is fixedly connected with a plugging column 406. The plugging column 406 is plugged into the inner clamping plate 201.

[0033] The connecting plate 405 is used for connecting the plugging column 406. The plugging column 406 is clamped with any one of the inner clamping plates 201 to lock the rotation of the main shaft 100, thereby locking the installation direction of the environmental detector.

[0034] The top end of the main shaft 100 is fixedly connected with a mounting plate 500.

[0035] The mounting plate 500 is used for installing the environmental detector.

[0036] Working principle:

[0037] Adjust the included angle of the inner clamping plate 201 according to the turning angle of the retaining wall. Since one end of the inner clamping plate 201 is hinged to each other, only the distance between the other ends needs to be adjusted to achieve the angle adjustment of the inner clamping plate 201.

[0038] Rotate the first handle 206 and the bidirectional threaded rod 205. The bidirectional threaded rod 205 drives the threaded sleeves 203 to approach or move away from each other. Since the rotating shaft 204 and the U-shaped plate 202 are rotatable, when the threaded sleeves 203 approach or move away from each other, the U-shaped plates 202 also approach or move away from each other accordingly, causing the two ends of the inner clamping plate 201 to approach or move away from each other, realizing the angle adjustment of the inner clamping plate 201.

[0039] Attach the adjusted inner clamping plate 201 to the inside corner at the top of the retaining wall, and support the L-shaped plate 301 with the retaining wall. Twist the second handle 304 to rotate the clamping threaded rod 303, pushing the outer clamping plate 302 closer to the wall surface. The outer clamping plate 302 and the inner clamping plate 201 clamp the wall surface.

[0040] Rotate the third handle 404 and the locking threaded rod 403 to make the side plates 402 approach each other, finally making the arc-shaped clamping plate 401 clamp the main shaft 100. Adjust the positions of the connecting plate 405 and the inserting column 406 so that the inserting column 406 is inserted into the inner clamping plate 201, realizing the locking of the main shaft 100. The environmental detector installed through the mounting plate 500 will not rotate abnormally.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
