Technical Field

The invention relates to an automatic water taking control device for a water delivery pipeline, in particular to a device for automatically taking water from a high position of a siphon.

Background

China is a big agricultural country, water conservancy irrigation is widely applied, water needs to be conveyed to a high place from a low place for irrigation in many places, a common method is to use a water pump, electric power and machine equipment are needed, and the water pump is inconvenient to apply in some wasteland fields. Although the siphon can transport the water flow to a high place, the water always flows only in the siphon channel and finally flows out at a low place. To extract the water flow from the high position of the siphon, the currently adopted methods require manual or electromechanical support. It would be a further advance in hydraulic engineering if the water flow could be automatically discharged from the siphon at a high level.

Disclosure of Invention

The invention aims to realize automatic water taking from a high position of a siphon pipeline so as to save manpower and material resources and further improve various hydraulic engineering.

The invention can be realized by the following technical scheme:

the utility model provides an automatic device of getting water from siphon high-order department which characterized in that: including inlet tube, outlet pipe, upper bin, lower bin, collection chamber, float A, float B, valve A, valve B, valve C, valve D, stereoplasm connecting rod, breather pipe and check valve, inlet tube and outlet pipe dress in the upper bin, the collection chamber dress is in the upper bin, open on the collection chamber top has the aperture, valve A, valve B communicate upper bin and lower bin, float A links to each other with valve B, the breather pipe under in the bin and communicate lower bin and external atmosphere, valve C, valve D install on the breather pipe, valve C links to each other with valve A, valve D links to each other with valve B, stereoplasm connecting rod upper end links to each other with valve A, the lower extreme links to each other with float B, the check valve install in lower bin.

The floater A, the valve A and the valve B are all positioned in the gas collection chamber.

An opening is formed in the bottom of the gas collection chamber and is communicated with the upper bin environment.

After the floater A rises to a certain degree, the linkage valve B is closed, the linkage valve D of the valve B is opened, and after the floater A descends to a certain degree, the linkage valve B is opened, and the linkage valve D of the valve B is closed.

After the floater B rises to a certain degree, the linkage valve A is closed, the linkage valve C of the valve A is opened, and after the floater B falls to a certain degree, the linkage valve A is opened, and the linkage valve C of the valve A is closed.

After the water in the lower bin is discharged by a certain amount through the check valve, the valve A is opened first, the air in the lower bin enters the air collection chamber of the upper bin through the valve A, then the valve B is opened, and the air in the lower bin enters the air collection chamber through the valve B.

Air in the air collection chamber is slowly discharged into the water outlet pipe through a small hole at the top end of the air collection chamber.

After the water inlet pipe of the device is connected to the high position of the siphon pipe, water flow is accumulated in the upper bin and the lower bin, and after the water flow is full of the water flow, the water flow is triggered to be automatically discharged from the check valve of the lower bin.

Compared with the prior art, the invention has the following advantages:

1. the structure is simple, and the manufacturing cost is low.

2. The installation is simple and easy, can use in most places.

3. After the device is started, manual intervention and power consumption are not needed, and the device runs in a full-automatic cycle.

[ detailed description ] embodiments

The following detailed description is provided in conjunction with the embodiments and with reference to the accompanying drawings in order to provide a further explanation of the technical features and advantages of the present invention.

The device is characterized in that a water inlet pipe (3) of the device is connected to a certain point at the high position of a siphon pipeline, a check valve (5) and a vent pipe (9) are temporarily blocked, then the water is reversely poured into an upper bin and a lower bin through a water outlet pipe (1), and the water outlet pipe (1) is connected into the original siphon pipeline after the siphon pipeline is filled with the water.

Then the temporary blockage of the check valve (5) and the vent pipe (9) is released, and the device starts to work. When filling water in the upper and lower bins, the floater A (13) pulls the valve B (6) to close, the floater B (10) props against the valve A (12) through the hard connecting rod (11) to close the valve A, after the valve A and the valve B are closed, the lower bin (4) is completely isolated from the siphon pipeline, at the moment, the valve C (7) and the valve D (8) are also opened under the linkage action, the outside air enters the lower bin, the water is discharged from the check valve (5) to the lower bin, and the water taking at the high position of the siphon is realized.

After the lower bin water is discharged to a certain degree, the floater B (10) descends to open the linkage valve A (12), the upper bin water flows into the lower bin, the lower bin air enters the upper bin air collection chamber (14), then the floater A (13) descends to open the linkage valve B (6), the upper bin water flows into the lower bin, the lower bin air enters the upper bin air collection chamber (14), and the air is discharged into the water outlet pipe (1) step by step through the small holes (15) in the top. Since the air is slowly discharged into the siphon tube, the siphon tube is not greatly affected, and the siphon stop is not caused. After the air is exhausted, water is full of again, and each valve linkage can be triggered again to drain water, so that automatic periodic water taking without manpower and electric power support is realized.

The present invention is described in detail and completely by the technical solutions in the above embodiments, and it is obvious that the described embodiments are a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained without inventive work based on the embodiments of the present invention belong to the protection scope of the present invention.
