Description

High-precision water speed measuring device based on recyclable use of floating mark method

Technical Field

The invention belongs to the technical field of buoy method speed measurement, and particularly relates to a recyclable high-precision water speed measuring device based on a buoy method.

Background

When sewage is detected and treated, not only the quality of the water body components of the sewage needs to be detected, but also the flow velocity of the sewage sometimes needs to be detected, one common method for detecting water flow is a buoy method, namely, a piece of wood or a bottle filled with a small amount of water is adopted, a striking flag is inserted on the wood or the bottle to form a buoy, then a section of distance is selected from a river channel, the river channels at two ends of the section of distance are marked, the buoy is placed into a river, and a timing device such as a watch is used for recording the time for the buoy to drift within the section of distance, so that the flow velocity of the river can be roughly calculated.

The float method is a simple and easy-to-make flow velocity measuring method, but the measured result of the method is too rough, a distance needs to be selected on a river channel, both ends of the distance are marked, then a measurer observes a float by naked eyes, a timer is pressed down when the float flows through a mark at a terminal end, firstly, when the measurer observes the position of the float, an observation error exists, and when the timer is pressed down after the float is observed, a hand speed error also exists, in addition, when the measurer at a starting end loosens the float, an error also exists in the time when the measurer at the terminal end receives the signal, the factors are accumulated, the measurement of the flow velocity of the water has larger deviation, the manufactured float floats with the water flow and is difficult to recycle, and more time is wasted when the float is manufactured every time.

Therefore, in view of the above, research and improvement are made for the existing structure and defects, and a high-precision water velocity measuring device based on a floating mark method and capable of being recycled is provided, so as to achieve the purpose of higher practical value.

Disclosure of Invention

In order to solve the technical problems, the invention provides a high-precision water speed measuring device based on a floating mark method, which is recyclable and is realized by the following specific technical means:

the utility model provides a high accuracy water speed measuring device based on circulated use of buoy method, which comprises a floating body, the inside fixed mounting of body has hourglass box, the grit has been placed to the inside of leaking the box, the middle part fixedly connected with home ring of hourglass box, the change has been cup jointed in the outside activity of home ring, the logical groove that is linked together with hourglass box is seted up at the middle part of home ring, the inside swing joint of home ring has the closure plate that the shutoff leads to the groove, swing joint has the connecting rod with closure plate looks articulated on the change, install the pressure spring subassembly on the change, the outside of change is connected with the fixing base through the rope, the outside movable mounting of change has the elastic button, set up the draw-in groove that corresponds with the elastic button on the outer wall.

Furthermore, a scale meter is arranged on the outer side of the leakage box, the residual amount of sand in the leakage box is observed, and the time consumed by sand flow loss is directly judged according to the skill of the scale meter.

Further, the closure plate is installed on the main ring through the articulated shaft, and the closure plate evenly distributed is in the outside of logical groove.

Furthermore, the joint of the connecting rod and the blocking plate is far away from the hinge shaft of the blocking plate connected with the main ring, so that when the rotating ring rotates, the blocking plate can be driven to rotate through the connecting rod, and the through groove is closed or opened.

Furthermore, a sliding groove corresponding to the rope is formed in the floating body, and the sliding groove is far away from the installation position of the rope and the rotating ring, so that the rotating ring can be driven to rotate when the rope is pulled to the end.

Further, install the winding roller that corresponds with the rope on the fixing base, the inside of fixing base is provided with the fixed slot, can pass through the fixed slot with the fixing base and install on objects such as vaulting pole, and then fix.

Further, the draw-in groove staggers with the elastic button, and when the change rotates along the closed direction of closure plate, the elastic button just can stretch into the draw-in groove, fixes the change.

Advantageous effects

Compared with the prior art, the invention has the following beneficial effects:

1. fix the fixing base, the body is along with rivers flow, when the flow distance of body reachs the length limit of rope, the change takes place to deflect under the pulling of rope, it is rotatory closed to drive the closure plate, to lead to the whole shutoff of groove, the grit also just also no longer flows, according to the reading of the graduation apparatus of leaking on the box, just can know how long time that the body flows, the position that the naked eye judged the body is manual again according to the method of time device that presses down of position, this device is confirmed the rope through the flow time of record grit and is opened used time completely, the rivers velocity of flow result that reachs is more accurate, and this device repeatedly usable, need not the repeated preparation body, and the measuring time is also saved, and is convenient to use.

2. In the initial state, the rotating ring is positioned under the action of the pressure spring assembly, and at the moment, most of the through groove is blocked by the blocking plate, and only one small opening is reserved, so that sand can slowly flow in the leakage box. When not using, the rope is accomodate through the winding roller winding on the fixing base, and the occupation space of whole device just only is a body and a fixing base, conveniently carries with oneself the use.

3. Before measuring the river course velocity of flow, confirm earlier whether grit all is located the one end of leaking the box, if not, then rotate the change, drive the closure plate rotation and open, will lead to the groove and all open to make the grit all flow in on one side fast, can guarantee the accuracy of timing, and easy operation is convenient.

4. Through setting up the elastic button on the change, when the change was rotatory along the closed direction of closure plate, when logical groove was plugged up completely, the elastic button stretched in the draw-in groove, fixed change avoided the closure plate rotation to open, ensured that the grit no longer flows, the error appeared when having avoided the body reading of back of getting back, has ensured measurement accuracy.
