Description

Technical Field

[0001] The utility model belongs to the technical field of drainage equipment, and particularly relates to a siphon - type energy - free drainage device. Background Technique

[0002] In urban areas and low - lying areas of farmland, when experiencing heavy rainfall, serious waterlogging may occur. Excessive waterlogging seriously affects people's normal production and life. The emergency rescue work mainly focuses on drainage, usually using a pumping station to pump out the water in the waterlogging area and discharge it externally. Chinese Patent CN204530641U discloses a siphon - type drainage device for low - lying farmland, and Chinese Patent CN219327173U discloses an emergency siphon drainage system applicable to anti - collapse of silt dams. It is found that although these technologies use the siphon principle for drainage, they all need to use water pumps, which not only require on - site power generation but also need personnel on duty, being rather inconvenient. Therefore, it is very necessary to develop a siphon - type energy - free drainage device. Content of the Utility Model

[0003] The purpose of the utility model is to provide a siphon - type energy - free drainage device.

[0004] The purpose of the utility model is realized as follows: it includes a water delivery pipe, an inlet valve, a drain valve, and an air - remaining valve. The water delivery pipe is bent. One end of the water delivery pipe is the water inlet end, and an inlet valve is installed at the water inlet end. The other end of the water delivery pipe is the water drainage end, and a drain valve is installed at the water drainage end. The water inlet end is higher than the water drainage end, and an air - remaining valve is provided on the pipe body near the water drainage end of the water delivery pipe;

[0005] The water delivery pipe is filled with water and has no gas. The water inlet end of the water delivery pipe is below the high liquid level, the water drainage end is below the low liquid level, and there is a height difference between the water inlet end and the water drainage end.

[0006] Preferably, both the inlet valve and the drain valve are globe valves.

[0007] Preferably, the water delivery pipe includes a water inlet pipe, a drain pipe, and an extension pipe. Both the water inlet pipe and the drain pipe are arc - shaped pipes, the extension pipe is a straight pipe, and the water inlet pipe is connected to the drain pipe through the extension pipe.

[0008] Wherein, for the connection between the water inlet pipe and the extension pipe, and the connection between the drain pipe and the extension pipe, they can both be installed together through clamps or other pipe connectors well - known to those skilled in the art.

[0009] Preferably, it further includes a pipe sleeve, a connecting plate, a connecting hose, a rotating rod sleeve, and a reinforcing rod. The water delivery pipe includes several sub-pipes. An inlet valve is installed at the pipe orifice of the sub-pipe at the head, and a drain valve is installed at the pipe orifice of the sub-pipe at the tail. An air residue valve is provided on the pipe body near the pipe orifice of the sub-pipe at the tail. Along the length direction of the pipe sleeve, waist-shaped through holes are respectively opened on both sides of the pipe sleeve. Rotating rod sleeves that are symmetrically arranged up and down are respectively rotatably provided at the front and rear ends on both sides of the pipe sleeve. There are several pipe sleeves arranged at intervals. A sub-pipe is fixedly provided inside one pipe sleeve. Adjacent sub-pipes are connected by a connecting hose. A connecting plate is provided between the waist-shaped through holes of adjacent pipe sleeves. One end of the connecting plate is connected to one waist-shaped through hole by a bolt, and the other end of the connecting plate is connected to the other waist-shaped through hole by a bolt. The rotating rod sleeves of adjacent pipe sleeves correspond to each other front and back. A reinforcing rod is inserted between two corresponding rotating rod sleeves. The locking bolt on the outside of the rotating rod sleeve passes through the rotating rod sleeve to hold the reinforcing rod against it.

[0010] Among them, the material of the pipe sleeve can be stainless steel, and the sub-pipe also selects a rigid material instead of a flexible hose; the connecting hose can be a metal hose, a corrugated pipe, a steel wire hose, etc.; for the connection between the sub-pipe and the connecting hose, it can be installed together through pipe connectors (such as clamps, pipe flanges, etc.) well-known to those skilled in the art; the rotational connection between the rotating rod sleeve and the pipe sleeve is a conventional setting, such as using a pin shaft.
