Further, a filter screen is arranged at one end of the water drawing pipe immersed in water.
Further, the water drawing pipe is a PE pipe and is fixed on the surface of the dam foundation through a pipe fastener.
Further, the exhaust pipe is a hard transparent pipe.
Further, the vacuum pumping mechanism is a vacuum pumping machine.
Further, the vacuumizing mechanism is a hand-operated air extractor.
The utility model has the following beneficial effects: the water drawing pipe of the simple water taking device is distributed along the reservoir dam body, so that the traditional way of paving the water drawing pipe through the dam body is changed, the leakage of the reservoir dam body caused by water taking is avoided, and the safety of the dam body is ensured; the water taking device is simple in accessory, convenient to construct and install, capable of being directly replaced after being damaged, low in cost, safe and reliable, and the dam body cannot be damaged secondarily.
Drawings
Fig. 1 is a schematic structural view of the device of the present utility model.
In the figure: 1-a water drawing pipe; 2-an exhaust pipe; 3-air pressure valve; 4-vacuumizing mechanism; 5-ball valve; 6-water outlet pool.
Detailed Description
The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.
Referring to fig. 1, the present utility model provides a siphon type simple water intake device, comprising: a water suction pipe 1, an exhaust pipe 2, and a vacuum pumping mechanism 4 connected to the exhaust pipe 2;
the drain pipe 1 is replaced by a PE pipe with threads, the drain pipe 1 is formed by connecting multiple sections through threads, the drain pipe 1 is paved along the dam foundation surface of the dam, the drain pipe is fixed on the dam foundation surface of the dam through pipe fasteners, two ends of the drain pipe are respectively located at two slope sides of the dam foundation, a filter screen is fixed at one end of the water inlet side, floats in water are filtered through the filter screen, the drain pipe 1 is prevented from being blocked, a ball valve 5 is arranged at one end of the water outlet side, the height of the ball valve 5 is lower than the height of the water surface, a water outlet pool 6 is arranged at the water outlet side, water discharged by the drain pipe 1 firstly impacts in the water outlet pool 6, and water is prevented from punching the downstream of the dam foundation.
The highest part of the water drawing pipe 1 is connected with an exhaust pipe 2 in a sealing way, the exhaust pipe 2 is communicated with the water drawing pipe 1, the other end of the exhaust pipe 2 is connected with a vacuumizing mechanism 4, air in the water drawing pipe 1 is pumped out through the vacuumizing mechanism 4 to form negative pressure, and siphon water intake is formed by utilizing the action of atmospheric pressure; the air pressure valve 3 is arranged on the exhaust pipe 2, when the negative pressure in the water drain pipe 1 is formed and the water flow reaches, the air pressure valve 3 is closed, so that the water drain pipe 1 is in a sealed state; the exhaust pipe 2 is a hard transparent pipe, so as to be convenient for observing whether the water flow reaches the highest position of the water drawing pipe 1.
The vacuum pumping mechanism 4 can be a vacuum pump or a hand-operated air pump or other devices capable of exhausting the air in the water suction pipe 1.
The working principle of the device is as follows: one end of the water drawing pipe 1 is immersed in water, the ball valve 5 is closed, the air pressure valve 3 is opened, the air in the water drawing pipe 1 is discharged by utilizing the vacuumizing mechanism 4, when the water is observed to enter the exhaust pipe 2, the air pressure valve 3 is closed, the vacuumizing mechanism 4 is removed, and the ball valve 5 is opened, so that water can be drawn. Closing the ball valve 5 can stop the water diversion. When the device is not used for a long time, the air pressure valve 3 can be opened to supplement air for the water drain pipe 1, so that the water condensation is prevented from freezing the water drain pipe 1 at a low temperature.
The foregoing is merely a preferred embodiment of the utility model, which is not representative of all possible forms of the utility model, and the scope of the utility model is not limited to such specific statements and embodiments. Various other modifications and improvements can be made in light of the teachings of the present disclosure without departing from the spirit and scope of the utility model.
