Description

Technical Field

[0001] The invention relates to the technical field of forestland water replenishment, in particular to an ecological water replenishment system for degraded forestland. Background Art

[0002] The original climate and geological problems are the main causes of ecological fragility, such as drought, high altitude, water shortage, steep terrain, easy erosion and thin soil. The more prominent problems are that water shortage exacerbates the dryness of the land surface and the reduction of surface organic matter cover exacerbates the thinning of the soil; vegetation in ecologically fragile areas often has difficulty surviving due to drought, and will be washed away with soil erosion when encountering short-term heavy rainfall, especially forest land is prone to collapse due to underdeveloped root systems due to long-term drought; therefore, soil and water conservation is a difficult problem for ecological restoration in ecologically fragile areas.

[0003] Therefore, how to provide an ecological water replenishment system for degraded forest land that can effectively carry out ecological water replenishment to increase soil moisture in degraded forest land, achieve soil and water conservation by slowing down the loss of surface organic matter cover in degraded forest land, accelerate the ecological environment recovery of degraded forest land and reduce construction costs is an urgent problem that technicians in this field need to solve. Summary of the invention

[0004] In view of this, the present invention proposes an ecological water replenishment system for degraded forest land, aiming to solve the technical problems of high construction cost of traditional forest land water replenishment methods and the inability to effectively maintain water and soil due to the inability to avoid the loss of surface cover and slow down the rate of water dissipation.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] The present invention provides a degraded forestland ecological water replenishment system, comprising:

[0007] A water storage tower assembly, wherein the water storage tower assembly is connected to a nearby water source to store water;

[0008] A soil-locking net, which is laid on the surface of the degraded forest land to be ecologically replenished with water;

[0009] A water supply main pipe, the water outlet of the water storage tower assembly is connected and communicated with one end of the water supply main pipe to supply water thereto, the other end of the water supply main pipe is sealed and extends in a direction away from the water storage tower assembly and is laid on the surface of the degraded forest land to be ecologically replenished with water; a water distributor is installed on the water supply main pipe;

[0010] A flexible branch pipe laying assembly, the flexible branch pipe laying assembly comprising a reel pipe releasing assembly, a pipe laying drone and a flexible branch pipe wound on the reel pipe releasing assembly; a plurality of irrigation holes are sequentially opened on the outer peripheral wall of the flexible branch pipe along the length direction; one end of the flexible branch pipe is detachably connected and connected to the water distributor; the reel pipe releasing assembly is suspended and connected to the pipe laying drone; the pipe laying drone can lift the reel pipe releasing assembly to shuttle through the forest area to be ecologically replenished, so as to unfold the flexible branch pipe wound on the reel pipe releasing assembly and lay it on the surface of the degraded forest land to be ecologically replenished, so as to form a multi-point irrigation and water replenishment structure for the forest land.

[0011] When the degraded forest ecological water replenishment system provided by the present invention is used, water is stored for irrigation through the water storage tower assembly, and water can be stored during the low electricity price period to reduce the water replenishment cost. The soil locking net is used to reinforce the forest surface to prevent soil loss and landslides, and the soil locking net can protect the stability of the organic cover layer on the surface, thereby locking the surface moisture and slowing down the dissipation rate of the surface moisture. During irrigation, the water storage tower assembly supplies water to the water replenishment main pipe, and the water replenishment main pipe supplies water to the flexible branch pipe. The multiple irrigation holes of the flexible branch pipe form a multi-point irrigation and water replenishment structure for the forest. The flexible branch pipe laying assembly of the present invention can greatly reduce the construction cost of the multi-point irrigation and water replenishment structure, making it simple and easy to arrange the water replenishment pipeline for the degraded forest land; when the flexible branch pipe is laid, the flexible branch pipe is initially wound on the reel pipe laying assembly, and the pipe laying drone can lift the reel pipe laying assembly to lay the pipe. Before laying the pipe, one end of the flexible branch pipe needs to be connected to the water distributor, and the running path of the pipe laying drone is controlled. The flexible branch pipe is unfolded from the reel pipe laying assembly under the action of tension and its own gravity and laid along the running path of the pipe laying drone to the surface of the degraded forest land to be ecologically replenished, so that the efficiency of pipe laying is greatly improved, and the labor intensity and construction cost are reduced; the pipe laying drone shuttles through the degraded forest land, and the severely degraded areas are smoothly bent for dense laying, which realizes flexible and convenient laying of water replenishment pipelines and constructs a multi-point irrigation and water replenishment structure for the forest land.

[0012] As a further improvement of the above technical solution, the reel pipe releasing assembly includes a hanging frame and a reel; before laying, the flexible branch pipe is wound on the reel; the reel is detachably rotatably connected to the bottom of the hanging frame; the top of the hanging frame is hinged to the lower end of the pipe-laying drone; when the pipe-laying drone lifts the hanging frame to move, the flexible branch pipe connected to the water distributor at one end pulls the reel to rotate, so as to unfold the flexible branch pipe from the reel and lay it on the surface of the degraded forest land to be ecologically replenished.

[0013] The beneficial effects of the above technical solution are: the flexible branch pipe is wound on the reel in an orderly manner to facilitate drone lifting. When the pipe-laying drone lifting suspension frame moves, one end of the flexible branch pipe is connected to the water divider as a fixed end. After it is unfolded for a period of time, its own gravity can also provide pulling force. The reverse pulling force of the flexible branch pipe can pull the reel to rotate on the suspension frame to gradually unfold and lay it along the running path of the pipe-laying drone.

[0014] As a further improvement of the above technical solution, there are multiple flexible branch pipes and multiple reels; multiple flexible branch pipes are wound one by one on the multiple reels and one end of each flexible branch pipe can be detachably connected and connected to the water distributor, and can be laid in parallel along the length direction of the water replenishment main pipe, so as to construct a multi-point distributed irrigation and water replenishment structure on the degraded forest land to be ecologically replenished.

[0015] The beneficial effects of the above technical solution are: the water distributor is connected to one end of multiple flexible branch pipes to distribute irrigation water to the multiple flexible branch pipes; the multiple flexible branch pipes are laid in parallel along the length direction of the water replenishment main pipe, forming a multi-point distributed irrigation water replenishment structure, forming a water replenishment network with a larger coverage area.

[0016] As a further improvement of the above technical solution, the soil locking net includes a bottom net, a top net, a connecting rope and a tree pull rope;

[0017] The bottom net is laid close to the surface of the degraded forest land to be ecologically replenished and fixed on the surface; the top net is laid above the bottom net, one end of the connecting rope is fixed to the bottom net, and the other end is fixed to the top net to connect the bottom net with the top net; the lower end of the tree pull rope is connected to the top net, and the upper end of the tree pull rope is connected to the upper part of the trees in the forest area and tensioned, so that when the trees sway, the top net can be pulled up by the pull rope and the covering on the top net can fall between the bottom net and the top net.

[0018] The beneficial effects of the above technical solution are: the bottom net is fixed on the ground to reinforce the forest surface and prevent the surface soil from loosening and shifting; a storage area for organic covering materials, loose soil blocks and other objects is formed between the top net and the bottom net; the forest trees are connected to the top net through tree ropes, and the tree ropes reinforce the forest trees to reduce their shaking amplitude, promote the rooting and growth of the trees and avoid falling over; when encountering strong winds, the swaying forest trees can pull the top net in the opposite direction through the tree ropes to lift the top net upward. When the top net is lifted upward, the leaves, bark and other covering materials on it can fall from the mesh of the top net to between the top net and the bottom net, and are thus constrained by the top net, which effectively collects the covering materials and prevents the loss of organic covering materials, further enhancing the coverage rate of the organic covering materials on the ground, thereby keeping the ground warm and slowing down the loss of surface water.

[0019] As a further improvement of the above technical solution, the bottom net and the top net are both stainless steel nets, the aperture of the bottom net is 5-10 cm; the aperture of the top net is 10-20 cm.

[0020] The beneficial effects of the above technical solution are: the mesh diameter of the bottom net is designed to facilitate the reinforcement of the surface soil of the forest without hindering the growth of herbaceous plants; after the coverage rate of herbaceous plants in the forest increases and the ecological water conservation function is restored, various trees and other species will be planned to be replanted to achieve a diversified ecological environment. The mesh diameter of the top net is designed to facilitate the passage of most organic coverings such as fallen leaves.

[0021] As a further improvement of the above technical solution, the two ends of the tree pull rope are detachably connected through a rope tightener to form an annular pull rope that can be connected between the top net and the corresponding tree.

[0022] The beneficial effects of the above technical solution are: the tree pull rope is arranged in a ring shape through the rope tightener, which can be easily installed and connected between the top net and the tree; the tree pull rope only needs to be connected around the tree branches and the top net to be quickly arranged, thereby improving construction efficiency.

[0023] As a further improvement of the above technical solution, the water tower assembly includes a water tower, a water pipe and a water pump; the water tower is arranged inside or in the surrounding area of ​​the degraded forest land to be ecologically replenished; the position of the water tower is higher than the water replenishment main pipe to form a water supply pressure difference; one end of the water pipe is connected to and connected to the water outlet of the water tower, and the other end is connected to a water source; the water pump is installed on the water pipe to pump water from the water source into the water tower.

[0024] The beneficial effect of the above technical solution is that the water storage tower should be located at a high terrain position inside or near the degraded forest land to be ecologically replenished, or installed at a high altitude through a bracket body to increase the water replenishment pressure difference between the water replenishment main pipe.

[0025] As a further improvement of the above technical solution, the water source is a surface river near the degraded forest land to be replenished with ecological water or an artificially excavated rainwater collection pool in the surrounding area of ​​the degraded forest land to be replenished with ecological water.

[0026] The beneficial effects of the above technical solution are: the selection of water sources can be reasonably selected according to the natural conditions of the forest area; surface rivers near the degraded forest land to be replenished with ecological water are preferred; if the surface rivers are far away, rainwater collection pools can be artificially excavated in low-lying areas around the forest to collect surrounding rainwater for irrigation, prevent rainwater loss, and effectively carry out ecological water replenishment.

[0027] As a further improvement of the above technical solution, it also includes organic covering, which is spread on the soil locking net to form a covering layer covering the surface of the degraded forest land to be ecologically replenished.

[0028] The beneficial effect of the above technical solution is that in areas with severe soil erosion in degraded forests, organic coverings can be covered on the soil-locking nets to form a covering layer on the surface, slowing down the loss of rainwater and irrigation water, thereby facilitating ecological restoration.

[0029] As a further improvement of the above technical solution, the organic covering includes any one of leaves, bark, crushed branches, pine needles, grass and fruit shells.

[0030] The beneficial effect of the above technical solution is that the selection of organic mulch can facilitate the reuse of discarded leaves, bark, branch crushed materials, pine needles, grass and fruit shells, which can not only provide organic fertilizer for the forest land but also protect the environment.

[0031] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a degraded forest ecological water replenishment system, which has the following advantages and beneficial effects:

[0032] 1. The present invention adopts the method of ecological water replenishment and organic covering to achieve water and soil conservation in degraded forest land, and can accelerate the ecological environment recovery of degraded forest land.

[0033] 2. The pipe network construction of the ecological water replenishment system of the present invention adopts flexible branch pipe laying components, and the flexible branch pipes are laid by drones to achieve efficient laying, which greatly reduces the difficulty of pipe laying and reduces construction costs.

[0034] 3. The present invention uses a double-layer soil-locking net to achieve the reinforcement of the surface soil layer and the effective collection of organic coverings, preventing the loss of water, soil and organic coverings, and avoiding the ecological imbalance of bare surface. In addition, the soil-locking net reinforces the trees through the tree rope, which is convenient for rooting and growth, and the tree lifting top net is convenient for the collection of organic coverings. The two are organically combined and complement each other, which is conducive to the restoration of the ecological environment. BRIEF DESCRIPTION OF THE DRAWINGS

During irrigation, the water storage tower assembly 1 supplies water to the water replenishment main pipe 3, and the water replenishment main pipe 3 supplies water to the flexible branch pipe 43. The multiple irrigation holes 431 of the flexible branch pipe 43 form a multi-point irrigation and water replenishment structure for the forest. The flexible branch pipe laying assembly 4 of the present invention can greatly reduce the construction cost of the multi-point irrigation and water replenishment structure, making it simple and easy to arrange the water replenishment pipeline for the degraded forest land; when the flexible branch pipe 43 is laid, the flexible branch pipe 43 is initially wound on the reel pipe release assembly 41, and the pipe laying drone 42 can lift the reel pipe release assembly 41 to lay the pipe. Before laying the pipe, one end of the flexible branch pipe 43 needs to be connected to the water distributor 31, and the running path of the pipe laying drone 42 is controlled. The flexible branch pipe 43 is unfolded from the reel pipe release assembly 41 under the action of tension and its own gravity and laid along the running path of the pipe laying drone 42 to the surface of the degraded forest land to be ecologically replenished, so that the efficiency of pipe laying is greatly improved, and the labor intensity and construction cost are reduced; the pipe laying drone 42 shuttles through the degraded forest land, and the severely degraded areas are smoothly bent for dense laying, which realizes flexible and convenient laying of water replenishment pipelines and constructs a multi-point irrigation and water replenishment structure for the forest land.

[0056] The flexible branch pipe 43 is wound on the reel 412 in an orderly manner for easy lifting by the drone. When the pipe-laying drone 42 lifts the suspension frame 411 and moves, one end of the flexible branch pipe 43 is connected to the water divider 31 as a fixed end. After it is unfolded for a period of time, its own gravity can also provide pulling force. The reverse pulling force of the flexible branch pipe 43 can pull the reel 412 to rotate on the suspension frame 411 to gradually unfold and lay the pipe along the running path of the pipe-laying drone 42.

[0063] The bottom net 21 is fixed on the ground to reinforce the forest surface and prevent the surface soil from loosening and shifting; a storage area for organic covering materials, loose soil blocks and other objects is formed between the top net 22 and the bottom net 21; the forest trees are connected to the top net 22 by tree pull ropes 24, and the tree pull ropes 24 reinforce the forest trees to reduce their shaking amplitude, promote the rooting and growth of the trees and avoid falling over; when encountering strong winds, the swaying forest trees can pull the top net 22 in the opposite direction through the tree pull ropes 24 to lift the top net 22 upward. When the top net 22 is lifted upward, the leaves, bark and other covering materials covering it can fall from the mesh of the top net 22 to between the top net 22 and the bottom net 21, so as to be covered and constrained by the top net 22, which effectively collects the covering materials and prevents the loss of organic covering materials, further strengthens the coverage rate of the organic covering materials on the ground surface, and then keeps the ground warm and slows down the loss of surface water.

[0072] In some embodiments, the water source is a surface river near the degraded forest land to be replenished with ecological water or an artificially excavated rainwater collection pool in the surrounding area of ​​the degraded forest land to be replenished with ecological water.

[0073] The water source can be reasonably selected according to the natural conditions of the forest area; surface rivers near the degraded forest to be replenished with ecological water are preferred; if the surface rivers are far away, rainwater collection pools can be artificially dug in low-lying areas around the forest to collect surrounding rainwater for irrigation, prevent rainwater loss, and effectively carry out ecological water replenishment.

[0074] In some embodiments, organic covering is also included, and the organic covering is spread on the soil locking net 2 to form a covering layer covering the surface of the degraded forest land to be ecologically replenished with water.

[0075] In areas where soil erosion in degraded forests is serious, organic coverings can be covered on the soil locking net 2 to form a covering layer on the surface, slowing down the loss of rainwater and irrigation water, so as to facilitate ecological restoration.
