Description

Technical Field

[0001] The utility model relates to the technical field of river section flow monitoring, in particular to a river section flow metering and monitoring instrument. Background Art

[0002] The river section flow meter monitor is an instrument used to measure the flow velocity and flow of a river or other water body at a specific section. It is widely used in water resource management, flood warning and environmental protection. River flow monitoring technology has been continuously developing with the advancement of science and technology, gradually evolving from traditional contact measurement methods to the now widely used non-contact radar monitoring technology.

[0003] River section flow metering monitors mainly use radar or acoustic Doppler technology to measure water flow velocity and water level. For example, a monitoring system using radar technology transmits and receives reflected microwave signals, calculates the signal propagation time to determine the distance from the water surface to the sensor, and then calculates the water level and flow rate.

[0004] The river section flow meter is one of the indispensable tools in modern water resources management and environmental protection. Through efficient and accurate flow monitoring, relevant departments can better carry out water resources allocation, flood prevention and ecological protection, and provide support for the sustainable development of society.

[0005] The river section flow metering and monitoring instrument generally includes support rods, cross bars, solar panels, radar flow monitoring structure and control box.

[0006] During use, since the radar flow monitoring structure and other equipment are generally arranged at the end of the cross bar, which is located above the water surface, when problems occur in the structure and maintenance and replacement are required, it is inconvenient for the user to maintain and replace the equipment because the equipment is above the water surface, which increases the difficulty of subsequent maintenance and replacement and brings inconvenience to subsequent maintenance and replacement.

DETAILED DESCRIPTION

[0038] 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.

[0039] A river channel cross-section flow metering and monitoring instrument comprises a bottom bar 10, a control box 11, a solar panel 14, a cross bar 12, and a radar monitor 13 connected to the end of the cross bar 12. The bottom bar 10, the control box 11, the solar panel 14, the cross bar 12, and the radar monitor 13 connected to the end of the cross bar 12 are all conventional structures of existing river channel flow monitors, so they are not described in detail.

[0040] In the examples of this application, please refer to Figure 1A self-rotating support rod 20 is rotatably provided at the top of the bottom rod 10. Specifically, the self-rotating support rod 20 includes a connecting rod 21 fixed to the top of the bottom rod 10, a rotating rod 22 is rotatably provided at the top of the connecting rod 21, a plane bearing 23 is provided between the rotating rod 22 and the connecting rod 21, and a stabilizing sleeve 24 rotatably sleeved on the top of the connecting rod 21 is fixedly sleeved at the bottom end of the rotating rod 22, a first bearing 25 is provided between the stabilizing sleeve 24 and the connecting rod 21, the solar panel 14 is provided on the top of the rotating rod 22, and the cross bar 12 is fixedly connected to the rotating rod 22. When necessary, rotating the rotating rod 22 can drive the cross bar 12 to rotate, thereby driving the radar monitor 13 to rotate, so that it rotates from above the measured river surface to the river bank, thereby facilitating the user to maintain and replace the radar monitor 13, increasing the convenience of later maintenance and replacement, and being more convenient for users to use.

[0041] Meanwhile, in another embodiment, please refer to Figure 1 and 3 A pulling frame 40 is connected to the rotating rod 22. Specifically, the pulling frame 40 includes a rotating sleeve 41 that is sleeved on the outside of the rotating rod 22 through a second bearing 42. The rotating sleeve 41 is fixedly connected to one end of a pull rope 43, and the other end of the pull rope 43 is fixed to the ground. Normally, the rotating rod 22 is pulled by the pull rope 43 to complete the pulling, so as to prevent the instrument from tipping into the river as a whole. At the same time, the rotating rod 22 and the rotating sleeve 41 can rotate relative to each other through the second bearing 42, thereby not affecting the rotating sleeve connection of the rotating rod 22.

[0042] In another embodiment, see Figure 1 and 2 The bottom end of the self-rotating support rod 20 is provided with an adjustment frame 30. Specifically, the adjustment frame 30 includes a fixed sleeve 31 fixedly sleeved on the outside of the stabilizing sleeve 24. A plurality of fixed rods 32 are fixed to the bottom of the fixed sleeve 31. A movable sleeve 33 sleeved on the outside of the bottom rod 10 is fixed to the bottom of the fixed rod 32. The inner diameter of the movable sleeve 33 is larger than the bottom rod 10 and the connecting rod 21, and can pass through the connection between the bottom rod 10 and the connecting rod 21. When the rotating rod 22 needs to be rotated, the user rotates the movable sleeve 33 or the fixed rod 32 to drive the fixed sleeve 31, the stabilizing sleeve 24 and the rotating rod 22 to rotate in turn.

[0043] Furthermore, a plurality of threaded holes 34 are provided inside the movable sleeve 33, and screws 35 are connected to the internal threads of the threaded holes 34. A pad is fixed to one end of the screw 35 close to the bottom rod 10, and the pad has a diameter smaller than the threaded hole 34. When in use, the screws 35 are tightened so that the pad is pressed against the bottom rod 10 to complete the fixation, preventing the movable sleeve 33 and the rotating rod 22 from rotating at will. In any case, they can rotate normally by loosening or unscrewing them.
