Abstract
The utility model provides a water flow scouring acts on force measuring device is by base, branch, handle, calibrated scale, pendulum rod, meet a class board, pivot, pointer and constitute. Base, branch, handle, pivot, the fixed setting of calibrated scale are in the same place, the pendulum rod, meet that a class board, pointer are fixed to be set up together to articulate in the pivot. The utility model discloses a water flow scouring acts on force measuring device adopts simple structure composing, and it is on -the -spot directly to be applied to laboratory or river, can direct measurement water flow scouring effort size. The student can see the water velocity concrete influence big or small to the water flow scouring effort in the laboratory directly perceivedly, can play very big help effect to teaching effects, can administer research for control flood from now on disaster alleviation and rivers provides important calculation parameter.
Description
Technical field
The utility model belongs to hydraulic engineering field, specifically current scour Force measurement device.
Background technology
Bank slope collapse problem needs one of major issue researched and solved badly in China's flood control and disaster reduction cause.Often can there is bank slope avalanche in the many rivers of China; especially some great rivers are fully and completely administered owing to lacking; river, many river courses gesture is unstable; Scour and Accretion is frequent; the phenomenon that seashore washes away avalanche is very general and serious; river bank collapse can cause river flood beach to run off, the safety of serious threat flood bank, even directly makes dyke ftracture and forms big flood.Collapse on the bank also destroys river gesture and stablizes, and causes many consequences being difficult to remedy in engineering along the river.In addition, collapse on the bank makes a large amount of farmland, bank lose, threaten port and pier, factories and miness safety along the river, and national economy is taken a bath.The influence factor that bank slope collapse destroys is numerous, and problem is complicated, therefore still not fully aware of to its mechanism of production so far, mostly still uses conventional methods by rule of thumb in prophylactico-therapeutic measures.Therefore, strengthen the desk research of current scour acting force further, flood control and disaster reduction and river management are of great immediate significance.Current research current are continued to use by the condition such as water velocity, the depth of water to the method for river bank scouring always, and with theoretical formula method, shop experiment is exactly measure flow rate of water flow usually.Thisly indirectly calculate current by flow velocity and have perfect space to river bank scouring method.Especially when imparting knowledge to students, student can only observation water Flow Velocity, can not grasp the concrete impact of water velocity on current scour amount of force.
Utility model content
In order to solve the above-mentioned technical matters existed in prior art, the utility model provides a kind of current scour
Force measurement device, by base, pole, handle, index dial, fork, meet stream plate, rotating shaft, pointer form, described base, pole, handle, rotating shaft, index dial are fixedly installed together.
Further, described fork, meet stream plate, pointer and be fixedly installed together, and be articulated with in rotating shaft.
Further, upper and lower section of described pole, fork are equipped with scalable, fixed mechanism.During test, device pedestal is placed in bottom of river channel, to ensure that whole test process device is in steady state (SS).
Current scour Force measurement device of the present utility model, adopts simple Structure composing, can directly apply to laboratory or river on-the-spot, can directly measure current scour amount of force.Student can be directly perceived in laboratory
The concrete impact of water velocity on current scour amount of force is seen on ground, can play very large help to teaching efficiency; Important computations parameter can be provided for flood control and disaster reduction and river management research from now on.
Accompanying drawing explanation
Fig. 1 is current scour Force measurement device front schematic view;
Fig. 2 is this device side schematic view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1-2, current scour Force measurement device of the present utility model by base 1, pole 2, handle 3, index dial 4, fork 5, meet stream plate 6, rotating shaft 7, pointer 8 form, wherein base 1, pole 2, handle 3, rotating shaft 7, index dial 4 are fixedly installed together; Fork 5, meet stream plate 6, pointer 8 and be fixedly installed together, and be articulated with in rotating shaft; Upper and lower section of pole 2, fork 5 are equipped with scalable, fixed mechanism, are convenient to the current scour acting force measuring different depth place.
Current scour Force measurement device principle of work of the present utility model: if meeting stream plate buoyant weight amount is W, area is A, and the horizontal direction making it rotate is made a concerted effort for P, and the horizontal direction stress making it rotate is
p, then
p=P/A, P and fork corner
βpass be P=Wsin
β/ cos
β, A is projected as A*cos in vertical face
β, so the horizontal direction stress making it rotate is
p=Wsin
β/ Acos2
β.Can find out from formula, along with fork corner increases
β, required horizontal direction stress is that p sharply increases, if
β=90
o, i.e. fork level, required horizontal direction stress is
pfor infinity.
When current scour Force measurement device of the present utility model uses: current scour Force measurement device pedestal is placed in bottom current and (meets stream plate face vertical with the flow direction), stream plate face is met in current scour, fork rotates (pointer synchronous axial system), record dial reading and fork corner
β , substitute into the scouring force size that formula can calculate measuring point.Measuring point equals experimental tank (or river course) bottom to rotating shaft apart from the height of experimental tank (or river course) bottom and highly deducts and meet the stream plate face centre of form and be multiplied by sin to rotating shaft distance
β.
