[0002] The steel ruler water level gauge is a type of water level measuring instrument. When measuring, the steel ruler with a probe sinks to the bottom of the water. The flow of river water will cause the probe to shift, so that the probe is not pointing vertically downward, resulting in errors in the steel ruler readings, and the probe cannot move underwater. Utility Model Content

[0006] As a further optimization of the technical solution, the control component of the inland waterway water level measurement and correction device of the utility model includes a rotating connector, a spring, a pawl, a ratchet, and a rotating handle. The rotating connector is rotatably mounted in a circular through hole set on the mounting frame in the manner of a ball bearing, a roller is fixedly mounted on one side of the rotating connector, and a ratchet is fixedly mounted on the other side of the rotating connector. The pawl is rotatably mounted in a groove set on the mounting frame, the pawl cooperates with the ratchet, a spring is fixedly mounted on the upper end of the pawl, the upper end of the spring is fixedly mounted on an extension plate set on the mounting frame, and a rotating handle is fixedly mounted on the ratchet.
[0007] As a further optimization of the technical solution, the connecting assembly of the inland waterway water level measurement and correction device of the utility model includes a frame, a rubber pad, a screw, and a rubber head. The frame is fixedly installed at the end of the line, a rubber pad is fixedly installed on the inner wall of the frame, a threaded through hole is provided on the frame, the frame is threadedly connected to the screw, and a rubber head is fixedly installed on the end of the screw.
[0008] As a further optimization of the technical solution, the wire of the inland waterway water level measurement and correction device of the utility model is wrapped by a plastic hose with anti-corrosion effect.
[0009] As a further optimization of the technical solution, the frame and screws of the inland waterway water level measurement and correction device of the utility model are made of stainless steel.
[0010] The beneficial effects of the inland waterway water level measurement and correction device of the utility model are:
[0011] Before launching the probe of the steel ruler water level gauge, insert it into the connecting assembly, and rotate the two screws separately to make the rubber head on the screw squeeze the probe, so as to fix the connecting assembly on the probe. The rubber pad and the rubber head protect the probe and fix the probe. When the probe is launched into the water, push the pawl upward to disengage the pawl from the spring. At this time, the line and the steel ruler of the steel ruler water level gauge are both performing the line-releasing operation. When the probe falls to the bottom of the river, stop the line-releasing operation, and insert the pawl between the teeth of the ratchet. When it is found that the probe is driven by the water flow to shift its position, rotate the ratchet by rotating the handle. The ratchet drives the drum to rotate through the rotating connecting piece to reel in the line. Every time the ratchet rotates one tooth, the line will be retracted a short distance, and the probe will be driven back one step through the connecting assembly until the probe is moved to the corresponding position, thereby achieving the purpose of correcting the position of the probe.

[0019] Embodiment 2: Based on the embodiment 1, the following is described. Figure 3 As shown, the control component 4 includes a rotating connector 41, a spring 42, a pawl 43, a ratchet 44, and a rotating handle 45. The rotating connector 41 is rotatably mounted in a circular through hole set on the mounting frame 2 in the form of a ball bearing. The roller 3 is fixedly mounted on one side of the rotating connector 41, and the ratchet 44 is fixedly mounted on the other side of the rotating connector 41. The pawl 43 is rotatably mounted in a groove set on the mounting frame 2, and the pawl 43 cooperates with the ratchet 44. The upper end of the pawl 43 is fixedly mounted with a spring 42, and the upper end of the spring 42 is fixedly mounted on an extension plate set on the mounting frame 2. The rotating handle 45 is fixedly mounted on the ratchet 44.
[0020] Embodiment 3: Based on the embodiment 1, the following is described. Figure 4 As shown, the connecting assembly 6 includes a frame 61, a rubber pad 62, a screw 63, and a rubber head 64.

The frame 61 is threadedly connected with the screw 63. The rubber head 64 is fixedly installed on the end of the screw 63. The frame 61 and the screw 63 are both made of stainless steel.
[0021] The inland waterway water level measurement and correction device of the present invention has the following working principles:
[0022] Before the probe of the steel ruler water level gauge is put into the water, it is inserted into the connecting assembly 6, and the two screws 63 are rotated respectively to squeeze the rubber head 64 on the screw 63 to fix the probe on the probe. The rubber pad 62 and the rubber head 64 serve to protect and fix the probe. When the probe is put into the water, the pawl 43 is pushed upward to disengage the pawl 43 from the spring 42. At this time, the line 5 and the steel ruler of the steel ruler water level gauge are both performing the line-releasing operation. When the probe falls to the bottom of the river, the line-releasing operation is stopped, and the pawl 43 is inserted between the teeth of the ratchet 44. When it is found that the probe is driven by the water flow to shift its position, the ratchet 44 is rotated by rotating the handle 45. The ratchet 44 drives the drum 3 to rotate through the rotating connecting piece 41 to reel in the line 5. Every time the ratchet 44 rotates one tooth, the line 5 will be retracted a short distance, and the probe will be driven back one step through the connecting assembly 6 until the probe is moved to the corresponding position, thereby achieving the purpose of correcting the position of the probe.
