The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of an integrated river water level high-precision measuring device of the invention, as shown in fig. 1 to 10, comprises a fixed disc 100, a sliding frame 200 and a containing channel 300.
The fixed tray 100 is fixedly mounted to a bridge floor or dam, or other stationary structure. The fixed disc 100 is provided with a rotary disc 110 which rotates around a vertical axis, and the rotary disc 110 is provided with a water level probe.
The sliding frame 200 moves along a first direction and is installed on the turntable 110 in a synchronous rotation manner with the turntable 110, the first direction is the water flow direction, and a water level probe is fixedly installed on the sliding frame 200; specifically, a sliding groove 111 along a first direction is disposed in the turntable 110, the sliding frame 200 is slidably mounted in the sliding groove 111, and the sliding frame 200 contacts with the sliding groove 111 to drive the turntable 110 to rotate synchronously.
The accommodating channel 300 comprises a shell 310, a first filter screen 320, a second filter screen 330 and a trigger assembly 340, wherein the shell 310 can slide up and down and is movably arranged on the sliding frame 200 along a first direction synchronously with the sliding frame 200, and a perspective hole 312 corresponding to the water level probe is formed at the upper end of the shell 310; the water level probe can be a laser water level gauge in the prior art, and the distance from the water level probe to the water surface in the shell 310 is monitored through the perspective hole 312 to calculate the height of the water level. The shell 310 is fixedly connected with a floating plate 311, and the floating plate 311 enables the shell 310 to be positioned partially under water and partially on water; specifically, the two floating plates 311 are respectively located at two sides of the housing 310 along the second direction, and the length of the housing 310 in the first direction is greater than the width of the housing 310 in the second direction, and the second direction is horizontal and perpendicular to the first direction, so that the housing 310 is easy to keep its long edge in the first direction under the action of the floating plates 311 and the water flow. The first filter 320 and the second filter 330 are disposed on two sides of the housing 310 along the first direction, and are perpendicular to the first direction, and the first filter 320 and the second filter 330 are in communication with the interior of the housing 310.
A first elastic member 140 is disposed between the sliding frame 200 and the fixed disk 100, and the first elastic member 140 can urge the rotation center of the sliding frame 200 to be located at the rear side of the center of the turntable 110 in the first direction;
the valve plate assembly is arranged in the shell 310, is positioned between the first filter screen 320 and the second filter screen 330, has a damping state and a natural state, and has resistance when the valve plate assembly is in the damping state and the water flow passes through the shell 310, so that the containing channel 300 is driven to move to the front side of the center of the turntable 110 along the first direction by the sliding frame 200; the resistance of the water flow through the housing 310 when the valve plate assembly is in the natural state is insufficient to cause the movement of the receiving passage 300, allowing the sliding frame 200 to move and return under the action of the first elastic member 140. The valve plate assembly can be switched from a damping state to a natural state or from the natural state to the damping state after being integrally turned 180 degrees.
The first screen 320 is slidably installed to the housing 310 in a first direction and is connected to the housing 310 through a second elastic member 321; the first screen 320 is moved in a first direction by the water flow when it is blocked, and the valve plate assembly is switched between a damped state and a natural state by the trigger assembly 340 when the first screen 320 is moved.
In the initial state, the first filter screen 320 is positioned at the water inlet side of the housing 310, the valve plate assembly is in a damping state, the rotation center of the sliding frame 200 is positioned at the front side of the center of the turntable 110 along the first direction, the sliding frame 200 is not easy to rotate under the action of water flow through the containing channel 300, and the water flow is discharged from the second filter screen 330 after entering the housing 310 from the first filter screen 320 and passing through the speed reduction of the valve plate assembly; the water level probe monitors the water level in the housing 310 to obtain current water level data of the river. With the first filter 320 blocked, the first filter 320 moves along the first direction relative to the housing 310 under the action of the water flow, and the valve plate assembly is switched from the damping state to the natural state by the triggering assembly 340, so that the resistance of the valve plate assembly to the water flow passing through is reduced, the sliding frame 200 moves and resets to the rear side of the center of the turntable 110 along the first direction under the action of the first elastic member 140, at this time, the housing 310 on the sliding frame 200 is easy to deflect under the impact and disturbance of the water flow, and when the housing 310 rotates and drives the sliding frame 200 to rotate 180 degrees, the rotation center of the sliding frame 200 is positioned at the front side of the center of the turntable 110 along the first direction; because the casing 310 drives the valve plate assembly inside to integrally turn over 180 degrees, the valve plate assembly is switched to a damping state, but because the first filter screen 320 is positioned on the water outlet side of the casing 310 after rotating 180 degrees along with the casing 310, impurities on the first filter screen 320 are washed away along with water flow and reset under the action of the second elastic piece 321, and the valve plate assembly is switched to a natural state through the trigger assembly 340. Because the resistance of the valve plate assembly to the water flow passing through the housing 310 is reduced, the sliding frame 200 moves to the rear side of the center of the turntable 110 along the first direction again under the action of the first elastic member 140, the housing 310 on the sliding frame 200 is easy to deflect under the impact and disturbance of the water flow, the housing 310 can continue to rotate along the original rotation direction or drive the sliding frame 200 to rotate 180 ° again along the opposite direction, the first filter screen 320 is positioned on the water inlet side of the housing 310 again, the valve plate assembly is switched to the damping state, the resistance of the valve plate assembly to the water flow makes the sliding frame 200 move to the front side of the center of the turntable 110 along the first direction again, and the whole device returns to the initial state.
The front side of the center of rotation of the sliding frame 200 along the first direction, which is located at the center of the turntable 110, means that the center of rotation of the sliding frame 200 is located at the downstream side of the center of the turntable 110, and the housing 310 is not easy to drive the sliding frame 200 to rotate under the action of water flow. When the rotation center of the sliding frame 200 is located at the rear side of the center of the turntable 110 along the first direction, the rotation center of the sliding frame 200 is located at the upstream side of the center of the turntable 110, and when the housing 310 is impacted by water flow, the sliding frame 200 is easily driven to rotate around the center of the turntable 110 by the sliding frame 200 while the first elastic member 140 is pressed by the sliding frame 200, until the sliding frame rotates again to the length direction of the housing 310 along the first direction, the housing 310 reaches a more stable state again, if the rotation center of the sliding frame 200 is located at the upstream side of the center of the turntable 110 again, the housing 310 rotates again until the valve plate assembly in the housing 310 is in a damping state, and the resistance to the water flow makes the housing 310 drive the sliding frame 200 to move to the downstream side of the center of the turntable 110, so that the housing 310 can not easily drive the sliding frame 200 to rotate.
According to the integrated river channel water level high-precision measuring device, in the initial state, the valve plate assembly is in the damping state, the resistance of water flow passing through the shell 310 is increased, so that the water flow entering the shell 310 passes through slowly, a water level probe can monitor the water level in the shell 310 conveniently, the influence of water flow disturbance on a measuring result is reduced, when the first filter screen 320 is blocked, the water flow washes impurities on the first filter screen 320 through the turnover of the shell 310, and then the shell 310 is turned back to the initial state again, so that the normal passing of the water flow is not influenced, and the influence of the blockage of the first filter screen 320 on the measuring result is reduced.

The first flow path increases resistance to water flow only when water flows from the first screen 320 to the second screen 330, and the second flow path increases resistance to water flow only when water flows from the second screen 330 to the first screen 320. The first and second valve plates 351 and 352 are rotated to open or close the first and second flow passages; when the valve plate assembly is in a damping state, the first flow passage is opened, and the second flow passage is closed; when the valve plate assembly is in a natural state, the first flow passage is closed, and the second flow passage is opened. When the valve plate component rotates 180 degrees in a natural state, the second flow channel can block water flow, and the valve plate component is switched to a damping state. Slowing down the flow rate of water entering the housing 310 by providing a first flow passage and a second flow passage in the shape of flow passages of tesla valves; after the shell 310 rotates until the first filter screen 320 is positioned on the water outlet side of the shell 310 and the first filter screen 320 moves and resets, the first flow channel is in an open state and has a promotion effect on the flow of water from the second filter screen 330 to the first filter screen 320, so that the water can be accelerated to recoil the first filter screen 320 through the first filter screen 320, and impurities on the first filter screen 320 are accelerated to be separated; and at this time, the resistance of the valve plate assembly to the water flow is small, so that the sliding frame 200 can be reset under the action of the first elastic member 140, and further the sliding frame is easy to rotate again due to the eccentricity with the turntable 110.
