Description

Technical Field

[0001] The utility model relates to the field of water conservancy engineering drainage, in particular to a non-powered drainage system. Background Art

[0002] In land reclamation or small- to medium-sized river and lake emergency drainage projects involving cofferdams (or levees), the water level in the site rises rapidly in a short period of time due to reasons such as the tail water of the reclamation or the convergence of heavy rains, and the water level difference with the outer drainage ditch or river channel increases sharply, posing a serious threat to the safety of the cofferdams (or levees).

[0003] At present, there are two common measures to deal with this phenomenon: one is to mobilize a large number of water pumps to drain water, and the other is to break the cofferdam (or dike) to release the flood. Since these waterlogged sites are generally remote and have insufficient power supply, pumping and draining water requires mobilizing high-power generators to provide electricity, which takes a long time and is expensive, and is not conducive to emergency drainage. Breaking the cofferdam (or dike) to release the flood will have a significant impact on the safety of the cofferdam (or dike) itself, and the subsequent repair will be very expensive. Utility Model Content

[0004] In order to solve the technical problems existing in the prior art, the utility model provides a non-powered drainage system, which cleverly utilizes the siphon phenomenon to discharge the accumulated water in the site out of the site in time.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A non-powered drainage system includes a non-powered drainage device, which includes a filter pipe head, a soft plastic pipe, a first pipe clamp, a second pipe clamp, and an exhaust pipe. The filter pipe head is connected to one end of the soft plastic pipe through a pipe clamp, and the other end of the soft plastic pipe is connected to the exhaust pipe through another pipe clamp. A one-way exhaust valve is provided on the exhaust pipe. The filter pipe head is fixed in a water collection well in a cofferdam, and the end of the soft plastic pipe close to the filter pipe head is a water inlet. The soft plastic pipe bypasses the cofferdam, and the end of the soft plastic pipe close to the soft plastic pipe is a water outlet. The elevation of the water inlet is higher than the elevation of the water outlet.

[0007] As a preferred technical solution, both pipe clamps are provided with fastening bolts.

[0008] As a preferred technical solution, the soft plastic tube is sealed and connected to the exhaust pipe, and a rubber sealing gasket is provided at the connection.

[0009] As a preferred technical solution, the depth of the water collection well is 1m.

[0010] As a preferred technical solution, the soft plastic tube is transparent in color.

[0011] As a preferred technical solution, when the drainage volume is large, the system includes multiple groups of unpowered drainage devices.

[0012] As a preferred technical solution, the maximum diameter of the soft plastic pipe does not exceed 200mm.

[0013] As a preferred technical solution, the exhaust pipe should be a hard pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The non-powered drainage system of the utility model is convenient and fast, does not require additional power, and can be used to drain water simultaneously by setting up multiple groups of non-powered drainage devices when the drainage volume is large. The maximum diameter of the transparent soft plastic pipe in the utility model does not exceed 200mm to prevent excessive air from entering the pipe. The exhaust pipe is a hard pipe to facilitate the sealing connection of the pipe clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the utility model is further described below in conjunction with specific implementation methods:

[0020] like Figure 1 As shown, a non-powered drainage system includes a non-powered drainage device, the device includes a filter pipe head, a soft plastic pipe 1, a first pipe clamp 3, a second pipe clamp 3, and an air extraction pipe 2. The filter pipe head is connected to one end of the soft plastic pipe 1 through a pipe clamp 3, and the other end of the soft plastic pipe 1 is connected to the air extraction pipe 2 through another pipe clamp 3. A one-way air extraction valve 4 is provided on the air extraction pipe 2. The filter pipe head is fixed in a water collection well 9 in a cofferdam 6 to reduce the violent jumping of the filter pipe head and the transparent soft plastic pipe 1 during the drainage process. The end of the soft plastic pipe 1 close to the filter pipe head is a water inlet 7, and the soft plastic pipe 1 bypasses the cofferdam 6. The end of the soft plastic pipe 1 close to the soft plastic pipe 1 is a water outlet 8, and the elevation of the water inlet 7 is higher than the elevation of the water outlet 8.

[0021] Both pipe clamps 3 are provided with fastening bolts 10. Figure 2As shown, each pipe clamp 3 includes two arc-shaped pieces arranged opposite to each other. By tightening the fastening bolt 10, the two arc-shaped pieces are clamped inward, so that the exhaust pipe 2 is hermetically connected to the soft plastic pipe 1. When necessary, a rubber sealing gasket is added to improve the sealing performance. The exhaust pipe 2 is a rigid pipe to facilitate the pipe clamp 3 to hermetically connect the exhaust pipe 2 to the soft plastic pipe 1.

[0022] Before installing the non-powered drainage device, a sump 9 is excavated to a depth of 1 m.

[0023] The soft plastic pipe 1 is transparent. The maximum diameter of the transparent soft plastic pipe 1 should not exceed 200 mm to prevent too much air from entering the pipe.

[0024] When the drainage volume is large, multiple groups of non-powered drainage devices can be set in the system to drain water simultaneously.

[0025] The working principle of the system is as follows: Utilizing the siphon phenomenon, the accumulated water in the site is drained out of the site in a timely manner. After the non-powered drainage device is installed, by pumping air through the one-way air extraction valve 4, the pressure inside the soft plastic pipe 1 is rapidly reduced. Under the action of the internal and external pressure difference, the accumulated water in the site enters the soft plastic pipe 1 through the filter pipe head, causing the liquid level inside the pipe to rise. After passing over the cofferdam 6 (or levee), it gradually advances forward until the soft plastic pipe 1 is filled with water. Then, place the water outlet 8 of the soft plastic pipe 1 at a position lower than the water inlet 7, disconnect the soft plastic pipe 1 from the exhaust pipe 2, and the liquid inside the soft plastic pipe 1 starts to flow under the action of the internal and external pressure difference, thereby realizing non-powered drainage inside and outside the cofferdam 6 (or levee).

[0026] This embodiment is only a further explanation of the present invention, not a limitation of the present invention. Those skilled in the art can make non-creative modifications to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
