[0024] 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.

[0025] Combined with Figure 1-5 In this embodiment, a river width surveying instrument capable of cross-bank detection includes: a connecting plate 11 is fixedly installed at the bottom of a lifting column 1.

[0026] Two level measuring instruments 12 are fixedly mounted on both sides of the top of the connecting plate 11 .

[0027] A support rod 13 is fixedly installed in the middle of the bottom of the connecting plate 11 , and a spherical rotating shaft 14 is fixedly installed at the bottom of the support rod 13 .

[0028] Specifically, the lifting column 1 is a structure for lifting. The horizontal angle of the connecting plate 11 can be detected by two level measuring instruments 12 on both sides of the top of the connecting plate 11, so that the connecting plate 11 can be adjusted to a horizontal state by rotating the spherical shaft 14 at the bottom of the support rod 13.

[0029] A bottom plate 2 is fixedly mounted on the bottom of the spherical rotating shaft 14 , and four mounting rotating shafts 21 are fixedly mounted around the bottom plate 2 .

[0030] A telescopic column 22 is fixedly mounted on the bottom of the mounting shaft 21 , and a fixing bolt 23 is movably connected to one side of the telescopic column 22 .

[0031] A retaining ring 24 is fixedly mounted on the bottom of the telescopic column 22 , and an insertion head 25 is fixedly mounted on the bottom of the retaining ring 24 .

[0032] Specifically, the connection support is carried out through the base plate 2. The rotation of the four mounting shafts 21 around the base plate 2 can drive the four telescopic columns 22 to adjust their positions. The height is adjusted by the telescopic columns 22. The telescopic columns 22 are fixed by rotating the fixing bolts 23. The insertion head 25 is inserted into the ground to support the whole. The retaining ring 24 is a structure used to prevent sliding down.

[0033] A supporting shaft 3 is fixedly installed on the top of the lifting column 1, and a placing plate 31 is fixedly installed on the top of the supporting shaft 3. The placing plate 31 is in a "U" shape. A laser rangefinder 32 is fixedly installed on one side of the bottom of the placing plate 31. Mounting bolts 33 are movably connected inside the two sides of the placing plate 31. A clamping plate 34 is movably connected to one side of the mounting bolts 33. A surveying instrument body 35 is movably connected to the middle of the top of the placing plate 31.

[0034] Specifically, by rotating the two mounting bolts 33 on both sides of the placement plate 31, the two clamping plates 34 can be driven to move toward the middle, and the surveying instrument body 35 can be clamped and fixed above the placement plate 31. The horizontal angle can be adjusted by supporting the rotating shaft 3, and the laser rangefinder 32 emits laser to illuminate the top of the reflector 41, so that distance measurement can be performed.

[0035] A telescopic rod 4 is provided at the end of the light source of the laser rangefinder 32, a reflector 41 is fixedly installed inside one side of the telescopic rod 4, a baffle 42 is fixedly installed on the top of the telescopic rod 4, a connecting block 43 is fixedly installed on the bottom of the telescopic rod 4, and four insertion rods 44 are fixedly installed around the bottom of the connecting block 43.

[0036] Specifically, the telescopic rod 4 is fixed to the opposite bank by four insertion rods 44 around the bottom of the connecting block 43, the height of the telescopic rod 4 is adjusted by lifting and lowering the telescopic rod 4, the baffle 42 is used to limit the position, and the reflector 41 is used in conjunction with the laser rangefinder 32 to measure the width.

[0037] Working principle: First, the angles of the four telescopic columns 22 are adjusted by rotating the four mounting shafts 21 around the base plate 2, and the telescopic columns 22 are adjusted to a suitable height by extending and retracting the telescopic columns 22. The fixing bolts 23 on one side of the telescopic columns 22 are rotated to fix the telescopic columns 22. The four telescopic columns 22 are inserted into the ground through the insertion heads 25 at the bottom for fixation. The retaining ring 24 is a limiting structure, which avoids the problem of sinking caused by too soft soil and improves the stability of the river width surveying instrument that can detect across banks. The rotation of the spherical shaft 14 at the top of the base plate 2 can drive the top connecting plate 11 of the support rod 13 to rotate 360 ​​degrees. The horizontal state of the connecting plate 11 can be detected by the two level measuring instruments 12 on both sides of the top of the connecting plate 11, and the connecting plate 11 can be adjusted to a horizontal angle by coordinating with the rotation of the spherical shaft 14. The surveying instrument body 35 is placed on the top of the placement plate 31. By rotating the two mounting bolts 33 on both sides of the placement plate 31, the two clamping plates 34 can be pushed to clamp from both sides to the middle, so as to clamp the surveying instrument body 35. The surveying instrument body 35 is fixed on the top of the placement plate 31. By operating the laser rangefinder 32 on one side of the bottom of the placement plate 31, a laser can be emitted to illuminate the opposite bank. The rotation of the supporting shaft 3 can drive the placement plate 31 to adjust the angle. The four insertion rods 44 around the bottom of the connecting block 43 at the bottom of the telescopic rod 4 are inserted into the opposite bank, so as to support the telescopic rod 4. The height can be adjusted by extending and retracting the telescopic rod 4. The telescopic rod 4 can be limited by the baffle 42. When the laser emitted by the laser rangefinder 32 illuminates the inside of the reflector 41 on one side of the telescopic rod 4, the width of the river channel can be detected.
