Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation equipment, in particular to a novel flexible prefabricated hole high-pressure water hose. Background Art

[0002] Drip irrigation uses plastic pipes to deliver water to the roots of crops through holes or drippers on a capillary tube with a diameter of about 10mm for local irrigation. During drip irrigation, water does not move in the air, does not wet the crop leaves, and does not evaporate from the soil surface outside the effective wet area. Therefore, the amount of water directly lost to evaporation is minimal, and the amount of water is easy to control, so that surface runoff and deep soil leakage will not occur. Therefore, it can save 35-75% of water compared to sprinkler irrigation, and has opened up a new way to realize water conservancy in mountainous areas with few water sources and water shortages. At the same time, since there is not enough water between crop plants, weeds are not easy to grow, which reduces the interference of crops and weeds in competing for nutrients, reduces the labor of weeding, and enables the root zone of crops to maintain the best water and fertilizer supply status, which can save water and labor, increase production and increase yield. It has the effect of harvesting and can also be used for irrigation of field crops in arid and water-scarce areas. When using drip irrigation to irrigate field crops, it is necessary to use a water pump and other power mechanisms to send water into the pipe, and arrange the pipeline in the field crop area. The pipeline includes a main pipe, a branch pipe, a capillary pipe and necessary regulating equipment, such as a pressure gauge, a gate valve, a flow regulator, etc., so as to evenly transport the pressurized water to the dripper. The main pipe part usually uses a high-pressure water hose to transport the water flow. The high-pressure water hose is made of polyethylene or polypropylene material. When in use, it is laid on the ground in the field, and the surface of the high-pressure water hose is punched with a punching device, and then the drip irrigation branch pipe is connected to the corresponding water outlet, and it is connected with an adhesive or a threaded pipe. The use process is time-consuming and labor-intensive, and the corresponding punching equipment needs to be carried during the operation.

[0003] In order to solve the problem of inconvenience in drilling holes during use, the surface of the high-pressure water hose can be pre-drilled before it is produced and shipped from the factory, so as to avoid the operation of temporary drilling during use. However, there is still the problem of inconvenience in connecting the high-pressure water hose with pre-drilled holes in the factory to the branch pipe. In addition, when the high-pressure water hose is in use, a large amount of water flows through the high-pressure water hose, and the surface of the high-pressure water hose is in contact with the ground. The high-pressure water hose over a long distance may be worn and leak, resulting in a waste of water resources. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-9 The utility model provides a technical solution: a new type of flexible prefabricated hole high-pressure water belt, including an outer water belt 1, an inner water belt 2, a connecting pipe 3, a supporting cavity 4, a water injection pipe 5, a connecting branch pipe 6, a stabilizing cavity 7, and a filter screen 8.

[0035] The outer water hose 1 and the inner water hose 2 are both made of high-quality polyethylene or polypropylene materials. The diameter of the inner water hose 2 is smaller than that of the outer water hose 1. The outer surface of the inner water hose 2 is provided with a connecting block of the same material fixedly connected to the inner wall of the outer water hose 1. A plurality of connecting blocks on the surface of the inner water hose 2 are arranged in an annular manner. The same circular through holes are arranged at corresponding positions on the upper surfaces of the outer water hose 1 and the inner water hose 2. The circular through holes on the surfaces of the outer water hose 1 and the inner water hose 2 are punched out using a punching device after the raw materials are extruded. Connecting pipes 3 are arranged at the circular through holes on the surfaces of the outer water hose 1 and the inner water hose 2. The outer surfaces of the connecting pipes 3 are fixedly connected to the outer water hose 1 and the inner water hose 2, respectively. The connecting pipes 3 are of an upper and lower through structure, and the inner wall of the connecting pipes 3 is provided with threads. The upper end of the connecting pipes 3 penetrates the upper surface of the outer water hose 1, and the lower end of the connecting pipes 3 penetrates the upper surface of the inner water hose 2.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Fig. 9 As shown, an outer water hose 1 of polyethylene or polypropylene is sleeved on the outer surface of the inner water hose 2, and the inner wall of the outer water hose 1 is connected to the outer surface of the inner water hose 2. The outer water hose 1 and the inner water hose 2 together constitute a double-layer drip irrigation high-pressure water hose. Before leaving the factory, circular prefabricated holes are pre-processed on the surfaces of the outer water hose 1 and the inner water hose 2, and connecting pipes 3 are fixedly installed in the holes. The inner wall of the connecting pipe 3 that passes through the upper and lower parts is provided with threads for convenient threaded connection with the drip irrigation branch pipe. The high-pressure water hose composed of the outer water hose 1 and the inner water hose 2 is laid on the surface of the field according to the pipe line design, so that the connecting pipe 3 faces upward, and the drip irrigation branch pipe is connected to the high-pressure water hose using the threads on the inner wall of the connecting pipe 3, thereby forming a completed drip irrigation pipeline.

[0037] A reinforcement structure is provided on the surface of the inner water hose 2. A support cavity 4 is provided between the outer water hose 1 and the inner water hose 2 to support and reinforce the inner water hose 2 to prevent the inner water hose 2 from directly contacting the ground and leaking. The reinforcement structure includes a support cavity 4, which is provided between the outer water hose 1 and the inner water hose 2. The support cavity 4 is made of the same material as the surfaces of the outer water hose 1 and the inner water hose 2. The support cavity 4 is a hollow cylindrical structure. The surface of the support cavity 4 is fixedly connected to the inner wall of the outer water hose 1. A plurality of support cavities 4 are provided in an annular manner between the inner water hose 2 and the outer water hose 1. A water injection pipe 5 is provided on the surface of one side of the inner water hose 2. The other end of the water injection pipe 5 is provided to penetrate the side surface of the outer water hose 1. A connecting branch pipe 6 is provided on the side surface of the water injection pipe 5. The other end of the connecting branch pipe 6 is provided to penetrate the side surface of the support cavity 4. The water injection pipe 5 and the connecting branch pipe 6 are both made of the same polyethylene or polypropylene material.

[0038] like Figure 5 , Figure 6 and Figure 7 As shown, after the pipeline is laid, the inner water belt 2 is injected with water using the water injection pipe 5 on one side, the water pumping device of the drip irrigation system is started, and water is injected from the water injection pipe 5. The water flows along the water injection pipe 5 into the inner water belt 2, flows along the inner water belt 2, and enters each branch pipe through the connecting pipe 3 to drip irrigate the field crops. When the water flows in the water injection pipe 5 to inject water into the device, the water path enters the support cavity 4 along the connecting branch pipe 6 on the side surface of the water injection pipe 5, so that the support cavity 4 is filled with water and bulges. The bulged branch pipe 6 is connected to the support cavity 4, and the support cavity 4 is filled with water and bulges. The supporting cavity 4 is located between the inner water hose 2 and the outer water hose 1, so that the outer water hose 1 is propped up. At this time, the outer water hose 1 is in contact with the field ground, while the inner water hose 2 inside is suspended in the air under the support of the supporting cavity 4. Under the protection of the outer water hose 1 and the supporting cavity 4, the inner water hose 2 filled with water has no contact with the ground, thereby avoiding the inner water hose 2 from being worn against the ground, causing leakage after the inner water hose 2 is damaged, and in long-distance field pipelines, leakage of the inner water hose 2 causing waste of water resources is avoided.

[0039] The surface of the outer water hose 1 is provided with a supporting structure, and a stabilizing cavity 7 is provided on the supporting structure, which is deformed during the process of water injection of the device, and supports the circular outer water hose 1 to prevent the device from tipping over. The supporting structure includes a stabilizing cavity 7, and the stabilizing cavity 7 is provided on the outer surface of the outer water hose 1. The stabilizing cavity 7 is made of polyethylene or polypropylene material, and the stabilizing cavity 7 is a long bag-shaped structure, and the inside of the stabilizing cavity 7 is hollow. One side surface of the long stabilizing cavity 7 is fixedly connected to the lower surface of the outer water hose 1, and the rest of the stabilizing cavity 7 is suspended. A water-passing cavity is provided on the surface of the stabilizing cavity 7, which penetrates the surface of the outer water hose 1 and is connected to the supporting cavity 4. Two stabilizing cavities 7 are symmetrically provided on the surface of the outer water hose 1, and the structures of the two stabilizing cavities 7 are exactly the same.

[0040] like Figure 4 , Figure 5 and Figure 6 As shown, two stabilizing chambers 7 are symmetrically arranged on the surface of the outer water hose 1, and the stabilizing chamber 7 is connected with the supporting chamber 4 inside the outer water hose 1. When water is injected into the supporting chamber 4 through the connecting branch pipe 6, the water flow inside the supporting chamber 4 enters the stabilizing chamber 7, so that the stabilizing chamber 7 is filled with water and bulges. Since one side surface of the stabilizing chamber 7 is fixedly connected to the lower surface of the outer water hose 1, and the rest of the stabilizing chamber 7 is suspended, under the action of the gravity of the water flow, one side of the long strip of stabilizing chamber 7 hangs down and contacts the ground of the field, and the stabilizing chambers 7 on both sides are filled with water at the same time, forming a symmetrical support leg structure on the surface of the outer water hose 1, supporting the device on the surface of the outer water hose 1, and preventing the device filled with water from tipping over on the ground of the field.

[0041] A filtering structure is arranged inside the connecting pipe 3, and a filter screen 8 is arranged in the filtering structure to filter the water flow to prevent impurities from entering the drip irrigation pipe with a smaller diameter and causing blockage. The filtering structure includes the filter screen 8, and the inner wall of the water injection pipe 5 is provided with a full circle of protrusions. The protrusions on the inner wall of the water injection pipe 5 are fixedly connected with the filter screen 8, and the filter screen 8 completely blocks the lower opening of the water injection pipe 5;

[0042] like Figure 5 , Figure 8 and Fig. 9 As shown, the water injection pipe 5 is provided with a whole circle of protrusions, and a filter screen 8 is fixedly installed on the protruding surface inside the water injection pipe 5. The filter screen 8 is connected and installed with the water injection pipe 5 to avoid the cumbersome operation of installing the filter screen 8 inside the inner water belt 2, and the water flow can also filter the water flow in the process of passing through the water injection pipe 5 with the filter screen 8. When water flows in the device, the water flow flows along the inner water belt 2, enters the water injection pipe 5, and enters the drip irrigation branch pipe along the water injection pipe 5 to drip irrigate the crops. In the process of the water flow entering the water injection pipe 5, the filter screen 8 on the surface of the water injection pipe 5 filters the water flow, and intercepts impurities in the water flow inside the inner water belt 2, preventing impurities from entering the drip irrigation branch pipe with a smaller diameter along the water injection pipe 5, causing blockage of the branch pipe and the dripper, and the impurities intercepted in the inner water belt 2 will continue to move along the water flow until they flow out of the inner water belt 2 after the device stops.

[0043] Working principle: When using the device for drip irrigation of fields, the device is laid on the surface of the field according to the set pipeline, the connecting pipe 3 on the surface of the outer water belt 1 is facing upward, and the stabilizing chamber 7 is facing downward in contact with the ground of the field, and the connecting pipe 3 on the surface of the device is used to connect with the drip irrigation branch pipe, and the branch pipe is connected to the device using the thread on the inner wall of the connecting pipe 3, so that the branch pipe and the device form a complete drip irrigation pipeline, and the pumping mechanism of the drip irrigation system is started to inject water into the device, and the water flows through the water injection pipe 5 into the inner water belt 2, and moves along the inner water belt 2, and enters the drip irrigation branch pipe from the connecting pipe 3 for drip irrigation. A filter screen 8 is set in the connecting pipe 3, so that when the water flows through the connecting pipe 3, impurities are intercepted by the filter screen 8 to prevent impurities from entering The drip irrigation branch pipe and the drip irrigation head are blocked in the branch pipe with a smaller diameter. When water flows in the water injection pipe 5 to inject water into the device, the water flows along the connecting branch pipe 6 on the side surface of the water injection pipe 5 and enters the support cavity 4, causing the support cavity 4 to swell with water. At the same time, the stabilizing cavity 7 connected to the support cavity 4 is also swollen with water. The swollen support cavity 4 has a supporting and separating effect between the outer water hose 1 and the inner water hose 2, preventing the inner water hose 2 from being directly contacted with the field ground and causing wear of the inner water hose 2, and water leakage causing waste of water resources. The swollen stabilizing cavity 7 forms a symmetrical support leg structure on both sides of the surface of the outer water hose 1, which has a stabilizing and supporting effect on the outer water hose 1, preventing the outer water hose 1 from tipping over during the water injection process of the device.
