Description

Technical Field

[0001] The present invention relates to the technical field of drainage, and in particular to an emergency drainage pipe and a drainage method. Background Art

[0002] In various water safety emergency response scenarios, such as emergency flood discharge from reservoirs under super-standard flood conditions, emergency drainage of reservoir dam areas in danger, pre-discharge of reservoir capacity during flood season, emergency drainage of embankment breaches, and emergency pumping and drainage of urban waterlogging, siphon pipes are often used as emergency rescue measures for water level control.

[0003] Siphon pipes are pressure water pipes that operate by utilizing the pressure difference between the atmospheric pressure at the upstream liquid level and the pressure inside the pipe. They are widely used in the field of water disaster prevention and control. However, siphon pipes still have obvious pain points and difficulties:

[0004] (1) High-flow siphonic drainage pipes are usually made of polyethylene (PE) or high-density polyethylene (HDPE), which are segmented, large-diameter, rigid pipes. They are not only inconvenient to store and take up a lot of space, but also require large volume and heavy weight to transport during emergency operations, which is not conducive to emergency rescue.

[0005] (2) The segmented pipeline structure has poor integrity and requires multiple people to organize and coordinate the installation. The segmented design is difficult to avoid the pain point of poor airtightness. The siphon effect construction process is cumbersome, and the entire paving process is extremely inconvenient, time-consuming and labor-intensive, and the emergency rescue efficiency is low.

[0006] (3) The complete set of drainage equipment is too strong but not flexible enough and has poor environmental adaptability, making it difficult to cope with extreme scenarios of dam rescue. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an emergency drainage pipe and a drainage method.

[0008] According to an embodiment of the first aspect of the present invention, the emergency drainage pipeline includes: a plurality of pipe segments connected in sequence, wherein each of the pipe segments is an air bag body, and the air bag body has an inflatable space. After the inflatable space is filled with gas, the pipe segment can expand to form a drainage channel separated from the inflatable space. After the inflatable spaces of all the pipe segments are filled with gas, the drainage channels of each pipe segment are connected in sequence; a sealing module is configured to be able to block the drainage channel of the pipe segment at the end, and also to unblock the drainage channel of the pipe segment at the end.

[0009] The emergency drainage pipe according to the embodiment of the present invention has at least the following beneficial effects:

[0010] When drainage is required with the aid of the emergency drainage pipe of the present invention, first, the emergency drainage pipe in a deflated state is laid at the drainage site, then the inflatable space in the pipe section at the end is inflated to expand the pipe section at the end, and a sealing module is inserted into the drainage channel of the pipe section at the end to block the drainage channel of the pipe section at the end; thereafter, the inflatable space in the pipe section at the head end is inflated to expand the pipe section at the head end, and then the head end of the pipe section at the head end is placed into the water body to be drained, wherein , the position of the head end of the pipe segment at the head end is higher than the end end of the pipe segment at the tail end; finally, the other pipe segments are inflated respectively to expand the other pipe segments and connect the drainage channels of all pipe segments, wherein, since the pipe segment at the tail end is sealed by the sealing module, the pipe segment at the head end is water-sealed, so that in the process of inflating the other pipe segments respectively, all drainage channels will generate negative pressure; finally, the sealing module is released from the drainage channel of the pipe segment at the tail end, and under the siphon effect, the upstream water can be discharged continuously.

[0011] Draining water with the emergency drainage pipe of the present invention has at least the following beneficial effects:

[0012] (1) The uninflated emergency drainage pipe is an air membrane, which is soft and can be folded at will, making it easy to store and transport; the inflated emergency drainage pipe can form a rigid channel structure with drainage capacity;

[0013] (2) The rigidity and flexibility of each pipe section can be controlled by controlling the amount of inflation, so it can be quickly and flexibly arranged on site to overcome terrain restrictions. The equipment has good integrity and does not require a large number of people to coordinate operations. The operation difficulty is low, which can greatly improve the efficiency of rescue operations.

[0014] (3) The pipe joint is made of lightweight materials and is inexpensive, overcoming the pain points of traditional polyethylene (PE) and high-density polyethylene (HDPE) pipes, such as high density, heavy weight, and high cost, and can be widely promoted and deployed;

[0015] (4) When the emergency drainage pipe forms a drainage channel with load-bearing capacity, a siphon effect can be constructed at the same time. After removing the sealing module, the water can be naturally drained under the action of potential energy difference, which is easy to operate.

[0016] According to some embodiments of the present invention, each pipe segment is further provided with an inflation hole communicating with the inflatable space therein, and a detachable hole plug is provided at the inflation hole.

[0018] According to some embodiments of the present invention, the sealing module is an inflatable seal. After the sealing module is inflated with gas, the sealing module expands, and the expanded sealing module can be clamped in the card slot; when the gas in the sealing module is released, the sealing module can be disengaged from the card slot.

[0019] According to some embodiments of the present invention, the emergency drainage pipe further includes a counterweight, and the counterweight is connected to the pipe joint at the head end.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is three or more.

[0047] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "mounted", "connected", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] As Figure 1 shown, an emergency drainage pipeline provided by an embodiment of the present invention includes a plurality of pipe sections 100 connected in sequence.

[0049] In one embodiment, the emergency drainage pipeline is made of air film material, and a plurality of diaphragms are arranged at intervals inside it along the length direction of the emergency drainage pipeline. The plurality of diaphragms divide the emergency drainage pipeline into a plurality of pipe sections 100.

[0050] Combined Figure 1 with Figure 2 , it can be understood that each pipe section 100 has an inflatable space 110. After the inflatable space 110 is filled with gas, it can cause the pipe section 100 to expand to form a drainage channel 120 separated from the inflatable space 110. Among them, the inflatable spaces 110 of each pipe section 100 are separated, and the inflatable space 110 of each pipe section 100 can be inflated separately.

[0051] Specifically, before inflation, the emergency drainage pipe can be arbitrarily folded due to its soft material, which is convenient for storage and transportation. After the inflatable space 110 inside it is inflated, it will expand into a tubular structure. At this time, the pipe section 100 is a rigid channel structure with drainage capacity.

[0052] Furthermore, after the inflatable spaces 110 of all the pipe sections 100 are filled with gas, the drainage channels 120 of the respective pipe sections 100 are connected in sequence. In this way, a drainage system with a relatively long length can be constructed.

[0053] It should be noted that each pipe section 100 is also provided with an inflation hole 130 communicating with the inflatable space 110 inside it, and a removable hole plug is provided at the inflation hole 130.

[0054] It can be understood that when it is necessary to inflate the pipe section 100, the hole plug can be removed, and then an air pump can be used to inflate the pipe section 100. After inflation is completed, the inflation hole 130 can be blocked by means of the hole plug again; when it is necessary to deflate, the hole plug can be pulled out.

[0055] As Figure 1 shown, the emergency drainage pipe further includes a sealing module 200, and the sealing module 200 is configured to be able to block the drainage channel 120 of the pipe section 100 at the end, and can also release the seal on the pipe section 100 at the end.

[0056] Define the pipe section 100 at the head end of all the pipe sections 100 as the head-end pipe section 101, and the pipe section 100 at the end of all the pipe sections 100 as the end-end pipe section 102. After the end-end pipe section 102 is inflated, the sealing module 200 can be used to seal the drainage channel 120 of the end-end pipe section 102. Of course, the sealing module 200 can also be operated to release the seal on the drainage channel 120 of the end-end pipe section 102 so that the drainage channel 120 of the end-end pipe section 102 can drain water normally.

[0057] When it is necessary to drain water with the aid of the emergency drainage pipe of the present invention, first, the emergency drainage pipe in a deflated state is laid at the drainage site, then the inflatable space 110 in the terminal pipe segment 102 is inflated to expand the terminal pipe segment 102, and the sealing module 200 is inserted into the drainage channel 120 of the terminal pipe segment 102 to block the drainage channel 120 of the terminal pipe segment 102; thereafter, the inflatable space 110 of the head end pipe segment 101 is inflated to expand the head end pipe segment 101, and then the head end of the head end pipe segment 101 is placed in the water body to be drained, wherein the position of the head end of the head end pipe segment 101 is higher than the end of the terminal pipe segment 102; finally Then, the other pipe segments 100 are inflated respectively to expand the other pipe segments 100 and connect the drainage channels 120 of all the pipe segments 100. Since the terminal pipe segment 102 is sealed by the sealing module 200 and the head pipe segment 101 is water-sealed, negative pressure will be generated in all the drainage channels 120 during the process of inflating the other pipe segments 100. Under the action of atmospheric pressure, the upstream water will be pressed into the drainage channels 120 to meet the starting conditions of the siphon effect. Finally, the sealing module 200 is released from the drainage channels 120 of the terminal pipe segment 100. Under the action of the potential energy difference, the upstream water can be continuously discharged.

[0058] The emergency drainage pipe of the present invention has at least the following beneficial effects:

[0059] (1) The uninflated emergency drainage pipe is an air membrane, which is soft and can be folded at will, making it easy to store and transport; the inflated emergency drainage pipe can form a rigid channel structure with drainage capacity;

[0060] (2) Each pipe segment 100 can control the structural rigidity and flexibility by controlling the inflation volume, so it can be quickly and flexibly arranged on site, overcoming terrain restrictions. The equipment has good integrity and does not require a large number of people to coordinate operations. The operation difficulty is low, which can greatly improve the efficiency of rescue operations.

[0061] (3) The pipe segment 100 is made of lightweight and inexpensive materials, which can overcome the drawbacks of high density, heavy weight, and high cost of traditional polyethylene (PE) and high-density polyethylene (HDPE) pipes, and can be widely deployed.

[0062] (4) When the emergency drainage pipe forms a drainage channel with load-bearing capacity, a siphon effect can be constructed at the same time. After removing the sealing module 200, the water can be naturally drained under the action of potential energy difference, which is easy to operate.

[0063] like Figure 3As shown, in some embodiments, after the inflatable space 110 of the end pipe section 102 is filled with gas, a clamping groove 140 is formed on the side wall of the drainage channel 120 of the end pipe section 102, and the sealing module 200 is configured to be clamped in the clamping groove 140 to block the drainage channel 120 of the pipe section 100 at the end.

[0064] It can be understood that after the inflatable space 110 of the end pipe section 102 is filled with gas, a clamping groove 140 is formed on the side wall of the drainage channel 120 of the end pipe section 102. The clamping groove 140 can limit the sealing module 200 to prevent the sealing module 200 from protruding from the drainage channel 120 of the end pipe section 102.

[0065] Furthermore, the sealing module 200 is an inflatable seal. When the sealing module 200 is filled with gas, the sealing module 200 expands, and the inflated sealing module 200 can be clamped in the clamping groove 140 to block the drainage channel 120 of the end pipe section 102; when the gas in the sealing module 200 is released, the sealing module 200 can protrude from the clamping groove 140.

[0066] It can be understood that the sealing module 200 is an airbag. When the sealing module 200 is inflated, the sealing module 200 expands to form a disc-shaped structure and can be clamped in the clamping groove 140 to block the drainage channel 120 of the end pipe section 102. When the sealing module 200 is deflated, the sealing module 200 can be disassembled.

[0067] It should be noted that the clamping groove 140 is an annular clamping groove, and the four sides of the inflated sealing module 200 can be inserted into the annular clamping groove. Among them, the inflation port of the sealing module 200 is located at its center and faces the end of the end pipe section 102, and relevant personnel can conveniently install and remove the plug to open or close the inflation port of the sealing module 200.

[0068] Combined with Figure 1 and Figure 4 , in some embodiments, the emergency drainage pipeline further includes a counterweight 300, and the counterweight 300 is connected to the first pipe section 101.

[0069] It can be understood that the counterweight 300 can sink the first end of the first pipe section 101 into the water body, thereby achieving the purpose of water sealing. At the same time, according to the required drainage volume, the depth of the first end of the first pipe section 101 sinking into the water body can be adjusted by the counterweight 300.

[0070] Among them, the counterweight 300 is connected to the first pipe section 101 through a rope 400.

[0071] In some embodiments, the length of the rope 400 is adjustable. For example, the length of the rope 400 can be adjusted by bundling.

[0072] In some other embodiments, there are various types of ropes 400, and ropes 400 of different types have different lengths. Ropes 400 of different types are optionally used to connect the counterweight 300 and the first pipe section 101. Thus, by selecting ropes 400 of different lengths, the depth of the first end of the first pipe section 101 sinking into the water body can be adjusted.

[0073] Among them, a loop 150 is provided on the first pipe section 101, and the rope 400 is connected to the loop 150.

[0074] As Figure 1 shown, the present invention also provides a drainage method, which applies the emergency drainage pipeline of the above embodiment. The drainage method includes:

[0075] S100, inflate the inflatable space 110 in the pipe section 100 at the end to expand the pipe section 100 at the end, and insert the sealing module 200 into the drainage channel 120 of the pipe section 100 at the end to block the drainage channel 120 of the pipe section 100 at the end;

[0076] S200, inflate the inflatable space 110 in the pipe section 100 at the first end to expand the pipe section 100 at the first end, and then place the first end of the pipe section 100 at the first end into the water body to be drained. Among them, the position of the first end of the pipe section 100 at the first end is higher than the end of the pipe section 100 at the end;

[0077] S300, inflate the other pipe sections 100 respectively to expand all the other pipe sections 100 so that the drainage channels 120 of all the pipe sections 100 are communicated;

[0078] S400, release the sealing of the drainage channel 120 of the pipe section 100 at the end by the sealing module 200.

[0079] When it is necessary to drain water with the aid of the emergency drainage pipe of the present invention, first, the emergency drainage pipe in a deflated state is laid at the drainage site, then the inflatable space 110 in the terminal pipe segment 102 is inflated to expand the terminal pipe segment 102, and the sealing module 200 is inserted into the drainage channel 120 of the terminal pipe segment 102 to block the drainage channel 120 of the terminal pipe segment 102; thereafter, the inflatable space 110 of the head end pipe segment 101 is inflated to expand the head end pipe segment 101, and then the head end of the head end pipe segment 101 is placed in the water body to be drained, wherein the position of the head end of the head end pipe segment 101 is higher than the end of the terminal pipe segment 102; finally Then, the other pipe segments 100 are inflated respectively to expand the other pipe segments 100 and connect the drainage channels 120 of all the pipe segments 100. Since the terminal pipe segment 102 is sealed by the sealing module 200 and the head pipe segment 101 is water-sealed, negative pressure will be generated in all the drainage channels 120 during the process of inflating the other pipe segments 100. Under the action of atmospheric pressure, the upstream water will be pressed into the drainage channels 120 to meet the starting conditions of the siphon effect. Finally, the sealing module 200 is released from the drainage channels 120 of the terminal pipe segment 100. Under the action of the potential energy difference, the upstream water can be continuously discharged.
