Fig. 2 is overlooking the structure diagram of the present utility model.
Embodiment
The utility model is described in detail below with reference to accompanying drawing：
As shown in Figure 1-2：
A kind of rectangular canal with flow monitoring, including bottom plate 1 and the side plate 2 positioned at the both sides of bottom plate 1, in the side plate 2
A cavity 3 is inside provided with, and bar shaped slideway 4 is offered towards the side inside channel in side plate 2, it is sliding in the bar shaped slideway 4
Dynamic to match somebody with somebody unification Pitot tube 5, the Pitot tube 5 is in horizontal positioned and can be slided up and down along slideway 4；Wear one end of the Pitot tube 5
Cross slideway 4 to extend in cavity 3, and the static pressure inlet of Pitot tube 5 is connected with the static tube 6 in the cavity 3, total crimp head with
Stagnation pressure tube 7 in cavity 3 is connected, and the static tube 6 and stagnation pressure tube 7 are extended downwardly in double helix, and in the side wall of side plate 2
Draw for connecting outside pressure tester bottom；The other end of the Pitot tube 5 connects a ball float 8, and the ball float 8 can be with
The change for liquid level drives Pitot tube 5 to move up and down and while ensures that Pitot tube 5 is located at certain depth under liquid level.
So, by the way that Pitot tube 5 is arranged on side plate 2, and moved up and down in the presence of ball float 8, in SEA LEVEL VARIATION
When can ensure that Pitot tube 5 is always positioned at certain depth under liquid, generally within the middle part of current, to ensure the accuracy of measurement；
During Pitot tube 5 is moved up and down, the double-spiral structure of static tube 6 and stagnation pressure tube 7 so that static tube 6 and stagnation pressure tube 7 have
There is certain elasticity, so as to ensure moving up and down for Pitot tube 5；Pitot tube 5 is passed through by determining the stagnation pressure and static pressure of current
After the exit of static tube 6 and stagnation pressure tube 7 is drawn, the outside pressure tester of connection, outside pressure tester can for U-tube or other
Electronic manometer, can be fixedly mounted on side plate 2 can also be carried by staff, so that reducing equipment carries quantity, be led to
Physical monitoring water velocity is crossed, cost is relatively low, and whole channel can in real time be monitored by unified connection realization.
