Abstract
Description
Technical Field
[0001] The present application relates to the technical field of planting equipment, and in particular to an irrigation water recovery system. Background Art
[0002] Greenhouses have been widely used in agricultural planting because they can grow crops that are not suitable for the current season or region. However, due to the closed environment of the greenhouse, water cannot be obtained from nature and artificial irrigation is required. If the irrigation water is allowed to be lost, it is easy to cause a waste of water resources. Utility Model Content
[0003] The purpose of this application is to provide an irrigation water recovery system to address at least one technical problem involved in the background technology.
[0004] In order to achieve the above objectives, this application adopts the following technical solutions:
[0005] The present application provides an irrigation water recovery system for being arranged under a greenhouse. The irrigation water recovery system comprises a storage unit and a pipeline unit, and a compacted soil layer, a first fine particle permeable layer and a permeable ground fabric arranged in sequence from bottom to top.
[0006] The pipeline unit includes a porous recovery pipe, a connecting pipe and a main recovery pipe.
[0007] The porous recovery pipe is located between the compacted soil layer and the first fine particle permeable layer, and the length direction of the porous recovery pipe extends along the top surface of the compacted soil layer.
[0008] The main recovery pipe is located below the compacted soil layer, the porous recovery pipe is connected to the main recovery pipe through the connecting pipe, and the main recovery pipe is connected to the storage unit.
[0009] Optionally, the connecting pipe is located in the middle or end of the porous recovery pipe in the length direction of the porous recovery pipe, and the top surface of the compacted soil layer gradually slopes downward from both ends of the porous recovery pipe to the position of the connecting pipe.
[0010] The beneficial effect of this technical solution is that: in this way, the porous recovery pipe placed on the top of the compacted soil layer is also inclined toward the position of the connecting pipe, so that the water in the porous recovery pipe is concentrated toward the connecting pipe, which makes it easier for the connecting pipe to concentrate the water flow to the main recovery pipe, making it difficult for irrigation water to be retained in the porous recovery pipe.
[0011] Optionally, the slope of the top surface of the compacted soil layer is 0.3% to 0.7%.
[0012] The beneficial effect of this technical solution is that it enables the water flow entering the porous recovery pipe to be concentrated to the connecting pipe at a faster speed, and also enables the porous recovery pipe to not occupy appropriate longitudinal space within a limited length.
[0013] Optionally, the irrigation water recovery system provided in the present application further includes a waterproof layer unit, wherein the waterproof layer unit is located below the porous recovery pipe and covers the compacted soil layer.
[0014] The beneficial effect of this technical solution is that the process of irrigation water seeping downward is completely blocked by the waterproof layer unit by providing the waterproof layer unit, thereby enabling the porous recovery pipe to collect more irrigation water.
[0015] Optionally, a second fine particle water-permeable layer is provided between the porous recovery pipe and the waterproof layer unit.
[0016] The beneficial effects of this technical solution are: on the one hand, before the porous recovery pipe is set, the second fine particle permeable layer is laid first to press the waterproof layer unit, so that the waterproof layer unit is not easy to move when the porous recovery pipe is set; on the other hand, the second fine particle permeable layer plays a certain isolation role, so that the porous recovery pipe will not be directly pressed on the waterproof layer unit, thereby avoiding the problem of damage to the waterproof layer unit caused by this; each fine particle permeable layer also plays the role of filtering irrigation water, so that impurities are not easy to clog the holes on the porous recovery pipe.
[0017] Optionally, the waterproof layer unit includes a geotextile and a waterproof cloth, the geotextile covers the compacted soil layer, and the waterproof cloth covers the geotextile.
[0018] The beneficial effect of this technical solution is that the geotextile is provided to isolate the waterproof cloth from the compacted soil layer, so that the waterproof cloth will not be damaged due to friction with the compacted soil layer, thereby avoiding the problem of irrigation water seeping downward from the damaged area.
[0019] Optionally, the waterproof layer unit includes two layers of geotextiles and two layers of waterproof cloth, and each layer of the waterproof cloth is located between the two layers of the waterproof cloth in the vertical direction.
[0020] The beneficial effect of this technical solution is that the geotextile located in the lower layer isolates the waterproof cloth from the compacted soil layer, so that the waterproof cloth will not be damaged due to friction with the compacted soil layer; the geotextile located in the upper layer isolates the waterproof cloth from the porous recovery pipe, so that the waterproof cloth will not be damaged due to friction with the porous recovery pipe. If two layers of waterproof cloth are provided and one layer of the waterproof cloth is damaged, the other layer of the waterproof cloth can still play a waterproof role, thereby improving the waterproof ability of the waterproof layer unit.
[0021] Optionally, the irrigation water recovery system provided in the present application further includes a coarse particle water permeable layer, wherein the coarse particle water permeable layer is located between the permeable ground cloth and the first fine particle water permeable layer.
[0022] The beneficial effect of this technical solution is that the coarse-grained permeable layer can filter impurities and also play a supporting role.
[0023] Optionally, non-woven fabric is wrapped around the porous recovery tube.
[0024] The beneficial effect of this technical solution is that the infiltrated irrigation water may still contain certain particulate impurities, and fine particle penetration layers are provided above and below the porous recovery pipe. Wrapping the porous recovery pipe with non-woven fabric can isolate the impurities in the irrigation water and the fine particles in each fine particle penetration layer by the non-woven fabric, and are not easy to enter the porous recovery pipe and block the porous recovery pipe.
[0025] Optionally, the pipeline unit includes a plurality of the porous recovery pipes and a plurality of the connecting pipes, each of the connecting pipes is connected to the main recovery pipe, and each of the porous recovery pipes is connected to each of the connecting pipes in a one-to-one correspondence.
[0026] The beneficial effect of this technical solution is that the provision of multiple porous recovery pipes and multiple connecting pipes improves the discharge efficiency of irrigation water.
[0027] The technical solution provided by this application can achieve at least one of the following beneficial effects:
[0028] The irrigation water recovery system provided by the present application can collect excess irrigation water in the greenhouse. The collected water can be reused, thereby improving the utilization rate of water resources and achieving the purpose of water conservation. At the same time, if the excess irrigation water is not collected, it will cause excessive moisture and humidity in the greenhouse, which is not conducive to the growth of vegetation. The irrigation water recovery system provided by the present application can allow the excess irrigation water to seep into the ground for collection, which is conducive to maintaining appropriate humidity in the greenhouse and improving the growth environment of vegetation. In addition, since fertilizers are often applied to the seedbeds or seedling trays, excess irrigation water will carry fertilizers out of the seedbeds or seedling trays. If this water is not collected, it will not only cause waste but also pollute groundwater. The irrigation water recovery system provided by the present application can collect the irrigation water with waste and reuse it, reducing fertilizer waste. It also makes it difficult for the water with fertilizers to continue to seep into the ground, reducing the chance of irrigation water polluting groundwater. In addition, a compacted soil layer is provided to prevent the irrigation water from seeping too quickly below the soil layer, so that most of the water can be recovered by the porous recovery pipe.
[0029] The irrigation water recycling system provided in the embodiment of the present application includes the following steps:
[0030] ①Bury the main recovery pipe below the greenhouse ground.
[0031] ② Slope the greenhouse floor according to the slope requirements (in the width direction, slope towards the porous recovery pipe; in the length direction, slope towards the main recovery pipe; the slope is generally 0.5%), and then compact it.
[0032] ③ Lay the geotextile on the compacted ground.
[0033] ④ Two layers of waterproof cloth are laid on top of the geotextile; the lower layer is domestic waterproof cloth, and the upper layer is imported waterproof cloth.
[0034] ⑤Lay a layer of geotextile on top of the waterproof cloth.
[0035] ⑥ Place a porous recovery tube on top of the geotextile.
[0036] ⑦ A layer of fine sand is laid on the porous recovery tube (wrapped with non-woven fabric) and geotextile.
[0037] ⑧Spread gravel on the fine sand until it reaches the ground.
[0038] ⑨Finally, lay a layer of floor cloth.
[0039] The additional technical features and advantages of this application will be more clearly explained in the following description, or can be understood through the specific practice of this application. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0055] like Figures 1 to 5 As shown, the present application provides an irrigation water recovery system for being arranged under a greenhouse. The irrigation water recovery system includes a storage unit and a pipeline unit, as well as a compacted soil layer 08, a first fine particle permeable layer 04 and a permeable ground fabric 02 arranged in sequence from bottom to top.
[0056] The pipeline unit includes a porous recovery pipe 09, a connecting pipe 01 and a main recovery pipe 10.
[0057] The porous recovery pipe 09 is located between the compacted soil layer 08 and the first fine particle permeable layer 04. The length direction of the porous recovery pipe 09 extends along the top surface of the compacted soil layer 08.
[0058] The main recovery pipe 10 is located below the compacted soil layer 08 . The porous recovery pipe 09 is connected to the main recovery pipe 10 via the connecting pipe 01 . The main recovery pipe 10 is connected to the storage unit.
[0059] In the embodiment of the present application, the first fine particle permeable layer 04 can be composed of fine sand, or can be paved with other small particles.
[0060] The irrigation water recovery system provided by the present application, when in use, uses the top surface of the permeable ground fabric 02 as the floor of the greenhouse, and places the seedbed or seedling tray 100 located in the greenhouse on the permeable ground fabric 02. When irrigating the vegetation in the seedbed or seedling tray 100, excess water drips onto the permeable ground fabric 02 through the seedbed or seedling tray 100, and gradually seeps into the first fine particle permeable layer 04, and enters the porous recovery pipe 09 through the holes on the porous recovery pipe 09. The porous recovery pipe 09 collects this water and sends it to the main recovery pipe 10 for recovery and then to the storage unit.
[0061] The irrigation water recycling system provided by the present application can collect excess irrigation water in the greenhouse. The collected water can be reused, which improves the utilization rate of water resources and achieves the purpose of water saving. At the same time, if the excess irrigation water is not collected, it will cause excessive moisture and humidity in the greenhouse, which is not conducive to the growth of plants. The irrigation water recycling system provided by the present application can make the excess irrigation water seep into the ground for collection, which is conducive to maintaining appropriate humidity in the greenhouse and improving the growth environment of plants. In addition, since more fertilizers are applied in the seedbed or seedling tray 100, the excess After the irrigation water flows out from the seedbed or seedling tray 100, it will carry fertilizer with it. If this water is not collected, it will not only cause waste of waste materials, but also pollute groundwater. The irrigation water recovery system provided by the present application can collect the irrigation water carrying waste materials and reuse this water, thereby reducing the waste of fertilizers and making it difficult for the water carrying fertilizers to continue to penetrate into the ground, thereby reducing the chance of irrigation water polluting groundwater; and, a compacted soil layer 08 is provided to prevent the irrigation water from penetrating too quickly below the soil layer, so that most of the water can be recovered by the porous recovery pipe 09.
[0062] Optionally, the connecting pipe 01 is located in the middle or end of the porous recovery pipe 09 along its length, and the top surface of the compacted soil layer 08 gradually slopes downward from both ends of the porous recovery pipe 09 to the location of the connecting pipe 01. In this way, the porous recovery pipe 09 placed on top of the compacted soil layer 08 also tilts toward the connecting pipe 01, concentrating the water flow in the porous recovery pipe 09 toward the connecting pipe 01, facilitating the centralized delivery of the water flow from the connecting pipe 01 to the main recovery pipe 10, and preventing irrigation water from being retained in the porous recovery pipe 09.
[0063] Optionally, the top surface of the compacted soil layer 08 has a slope of 0.3% to 0.7%. For example, the top surface slope of the compacted soil layer 08 can be 0.4%, 0.5%, or 0.6%. This allows the water entering the porous recovery pipe 09 to be concentrated toward the connecting pipe 01 at a faster rate, while also preventing the porous recovery pipe 09 from occupying excessive longitudinal space within its limited length.
[0064] Optionally, the irrigation water recovery system provided in the embodiment of the present application further includes a waterproof layer unit, which is located below the porous recovery pipe 09 and covers the compacted soil layer 08. By providing the waterproof layer unit, the downward infiltration of irrigation water is completely blocked by the waterproof layer unit, thereby allowing the porous recovery pipe 09 to collect more irrigation water.
[0065] Optionally, a second fine-particle permeable layer is provided between the porous recovery pipe 09 and the waterproof layer unit. This firstly allows the second fine-particle permeable layer to be laid before the porous recovery pipe 09 is installed, pressing down on the waterproof layer unit. This prevents the waterproof layer unit from moving when the porous recovery pipe 09 is installed. Furthermore, the second fine-particle permeable layer provides a certain degree of isolation, preventing the porous recovery pipe 09 from directly pressing against the waterproof layer unit, thereby avoiding damage to the waterproof layer unit. Each fine-particle permeable layer also filters the irrigation water, preventing impurities from clogging the pores of the porous recovery pipe 09.
[0066] Optionally, the waterproof layer unit includes a geotextile 05 and a waterproof fabric 06, wherein the geotextile 05 covers the compacted soil layer 08, and the waterproof fabric 06 covers the geotextile 05. The geotextile 05 is provided to isolate the waterproof fabric 06 from the compacted soil layer 08, so that the waterproof fabric 06 will not be damaged by friction with the compacted soil layer 08, thereby avoiding the problem of irrigation water seeping downward from the damaged area.
[0067] Optionally, the waterproof layer unit includes two layers of geotextiles 05 and two layers of waterproof fabrics 06, with each layer of waterproof fabric 06 vertically positioned between two layers of the geotextiles 06. The lower geotextile 05 isolates the waterproof fabric 06 from the compacted soil layer 08, preventing the waterproof fabric 06 from being damaged by friction with the compacted soil layer 08. The upper geotextile 05 isolates the waterproof fabric 06 from the porous recovery tube 09, preventing the waterproof fabric 06 from being damaged by friction with the porous recovery tube 09. If one of the two layers of waterproof fabric 06 is damaged, the other layer can still function as a waterproof layer, thereby enhancing the waterproof capability of the waterproof layer unit. Of course, only one layer of waterproof fabric 06 can also be positioned between the two layers of geotextiles 05.
[0068] Optionally, the irrigation water recycling system provided in this embodiment further includes a coarse-grained permeable layer 03, located between the permeable ground fabric 02 and the first fine-grained permeable layer 04. In this embodiment, the coarse-grained permeable layer 03 can be composed of gravel or filled with large particles such as coal slag. The coarse-grained permeable layer 03 can filter impurities and also provide support.
[0069] Optionally, a non-woven fabric may be wrapped around the porous recovery pipe 09. The permeated irrigation water may contain certain particulate impurities, and fine particle permeation layers are provided above and below the porous recovery pipe 09. Wrapping the porous recovery pipe 09 with the non-woven fabric isolates impurities in the irrigation water and fine particles in the fine particle permeation layers, making it difficult for the non-woven fabric to enter the porous recovery pipe 09 and clog it.
[0070] Optionally, the piping unit includes multiple porous recovery pipes 09 and multiple connecting pipes 01, each of which is connected to the main recovery pipe 10, and each of the porous recovery pipes 09 is connected to each of the connecting pipes 01 in a one-to-one correspondence. The provision of multiple porous recovery pipes 09 and multiple connecting pipes 01 improves the drainage efficiency of irrigation water. In the embodiment of the present application, preferably, each porous recovery pipe 09 is arranged parallel to each other; each porous recovery pipe 09 is preferably arranged perpendicular to the main recovery pipe 10. Of course, the porous recovery pipes can also be arranged crosswise.
[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
