Abstract

The utility model discloses a river channel flow velocity detection device which comprises a support rod, a propelling device, a detection device, a support plate, a wind-up roll, a wire loop and a traction rope, wherein the left side of the bottom of the propelling device is fixedly connected with the top of the support rod. According to the utility model, the worm wheel and the worm are arranged, when a user needs to descend the detection device to the bottom of a river channel, the worm wheel is rotated to drive the worm wheel to rotate, so that the winding roller gradually unwinds the traction rope, the detection device descends, then after the detection device reaches a certain depth, the rotation of the worm is stopped, the detection device is finally stabilized at the height through the self-locking capability between the worm wheel and the worm, the problem that the control panel receives larger reverse torque as the tension born by the control rope increases as the detection device approaches the bottom of the river channel, the friction force between the control bolt and the fixed plate is the key for fixing the position of the control panel, and the effect of stabilizing the height is achieved under the action of the larger torque is solved.

Description

River flow velocity detection device Technical Field The utility model relates to the technical field of water area monitoring, in particular to a river channel flow velocity detection device. Background The monitoring of river flow is an important content of hydrologic work, and relates to aspects such as flood control safety, water resource development and utilization and the like. The utility model discloses a river flow rate monitoring device, which belongs to the field of water area detection and comprises a positioning column, a cross beam, a telescopic rod, a connecting plate, a flow rate sensor, a control assembly and a control assembly, wherein the cross beam is arranged on the positioning column, the driving assembly is arranged on the cross beam, the telescopic rod is connected with the driving assembly, the connecting plate is arranged at the bottom of the telescopic rod, the flow rate sensor is arranged at the bottom of the connecting plate, and the control assembly is arranged on the cross beam and is used for controlling the length of the telescopic rod. Through the setting of telescopic link, make the device carry out the velocity of flow to the river and detect the time measuring, the telescopic link can carry out the corresponding regulation of length according to the difference of the degree of depth of river to avoided because of the river is dark, velocity of flow sensor can not detect the problem of river bottom velocity of flow, and avoided because of the river bottom is shallower, the device can not normally install the problem, improved the adaptability of device to different river departments.
