DETAILED DESCRIPTION

[0049] The present application will be further described in detail below with specific examples and in conjunction with the accompanying drawings.

[0050] Embodiment:

[0051] Reference is made to Figure 1 and Figure 2The embodiment of the application discloses a water-saving ecological restoration device for arid regions, which comprises a pipeline network 100, a water filter tank 300, a water supplement pipe 700, a floating block 400, a water pumping pipe 500, a water pump, a water collecting tank 600, an intermittent water supply structure 800, the water supplement pipe 700 and a plurality of water receiving basins 200. The plurality of water receiving basins 200 are arranged at intervals on the pipeline network 100, and the pipeline network 100 is finally communicated with the water filter tank 300. The floating block 400 is slidably connected with the water filter tank 300, the floating block 400 can move along the height direction of the water filter tank 300, one end of the water pumping pipe 500 is installed on the floating block 400 for pumping water, the other end of the water pumping pipe 500 extends out of the water filter tank 300, and a water pump is arranged on the water pumping pipe 500. The end of the water pumping pipe 500 extending out of the water filter tank 300 is communicated with the water collecting tank 600, and the water supplement pipe 700 for supplementing water to the water collecting tank 600 is further arranged, and the intermittent water supply structure 800 is used for intermittently supplying water in the water collecting tank 600 to plants, so that the growth of the plants is ensured without wasting water.

[0052] The water-saving ecological restoration device for arid regions disclosed by the embodiment can effectively collect rainwater, spray the basically clean water to plants after filtration, ensure the basic needs of plant growth, supplement the water in the water collecting tank 600 by the water supplement pipe 700, so that the plants can obtain the basic necessary water source even in a long time without rain, the water-saving ecological restoration device can effectively utilize the precious rainwater in arid regions and save water resources on one hand, and the growth of plants can be ensured by the arrangement of the water supplement pipe 700, so that the planted plants can grow normally, thereby adding vitality to the arid regions and gradually repairing the ecology.

[0053] Referring to Figure 1 The pipeline network 100 is composed of a plurality of interlaced pipes, the water receiving basins 200 are arranged at intervals on the pipeline network 100, and each water receiving basin is communicated with the pipeline network 100. When it rains, the rainwater can be collected by the water receiving basins 200 and then transported to the water filter tank 300 along the pipeline network 100, and the water can be utilized after filtration by the water filter tank 300.

[0054] Because there are fewer plants and more wind and sand in arid regions, the rainwater usually contains more dust and mud when it rains, the dust and mud can be effectively filtered by the water filter tank 300, and then the basically pure water is sprayed to the plants, so that the needs of plant growth are met, the plants gradually grow over time, the root system can ensure that the soil does not be lost, and then the root system continues to expand to the arid regions, so that the arid regions are gradually filled with green plants, and the purpose of ecological restoration is achieved.

[0055] Referring to Figure 2 and Figure 3The filter water tank 300 is used to store rainwater and can also filter the rainwater. A filter screen 310 is arranged in the filter water tank 300, and the filter screen 310 divides the cavity in the filter water tank 300 into a first cavity 320 and a second cavity 330. The second cavity 330 is in communication with the pipeline network 100, and rainwater collected by the pipeline network 100 can directly flow into the second cavity 330. The first cavity 320 is located on the other side of the filter screen 310, and clean water filtered by the filter screen 310 can flow into the first cavity 320. The water pump 500 and the float 400 are both located in the first cavity 320.

[0056] A wedge-shaped block is also arranged in the first cavity 320. The diameter of the wedge-shaped block gradually decreases along the direction from the bottom of the filter water tank 300 to the top of the filter water tank 300. The wedge-shaped block is located on the moving path of the water pump 500. When the water level in the first cavity 320 decreases, the float 400 moves downward and drives the nozzle of the water pump 500 to move downward. In this process, the portion of the nozzle of the water pump 500 restricted by the wedge-shaped block becomes larger and larger, so that the pumping speed of the water pump 500 becomes smaller and smaller. In this way, the speed at which water in the filter water tank 300 is pumped out can be reduced, so that water can be continuously provided for plants.

[0057] In the embodiment, the bottom plate 370 corresponding to the second cavity 330 of the filter water tank 300 is in sliding connection with other parts of the filter water tank 300. When the water in the filter water tank 300 is pumped out or the filter water tank 300 has not been drained for a long time, the sludge in the second cavity 330 can be discharged by moving the bottom plate 370, so as to avoid blocking the filter screen 310.

[0058] Referring to Figure 3 An installation frame 340, a sleeve 350, and a second elastic member 360 are arranged on the filter water tank 300. The installation frame 340 is located on the side wall of the filter water tank 300, and the sleeve 350 is in sliding connection with the installation frame 340. The two ends of the second elastic member 360 are connected with the installation frame 340 and the sleeve 350 respectively, and the second elastic member 360 causes the sleeve 350 to have a tendency to move away from the filter water tank 300. The end of the water pump 500 extending out of the filter water tank 300 is fixedly connected with the sleeve 350. The sleeve 350 can be used to drag the water pump 500 to move outward, so as to avoid affecting the upward and downward movement of the float 400 when the water pump 500 accumulates in the filter water tank 300.

[0059] Referring to Figure 2 and Figure 4 and Figure 5The water collecting tank 600 is fixedly connected with the water filtering tank 300, one end of the water pumping pipe 500 extending out of the water filtering tank 300 is communicated with the water collecting tank 600, and the water collecting tank 600 is used for temporarily collecting clean water, so as to facilitate the intermittent water feeding structure 800 to feed water to plants. The liquid feeding opening 640 is arranged on the sidewall below the water collecting tank 600, the dripping head 820 is communicated with the liquid feeding opening 640, and the size of the liquid feeding opening 640 determines the dripping speed of the dripping head 820. The water collecting tank 600 is further provided with the control block 610 at the liquid feeding opening 640, the control block 610 is slidably connected with the water collecting tank 600, and the control block 610 can move along the height direction of the water collecting tank 600. When the control block 610 moves towards the top of the water collecting tank 600, the control block 610 makes the liquid feeding opening 640 smaller, and at this time, the dripping speed of the dripping head 820 is reduced; when the control block 610 moves towards the bottom of the water collecting tank 600, the control block 610 makes the liquid feeding opening 640 larger, and at this time, the dripping speed of the dripping head 820 is increased.

[0060] The intermittent water feeding structure 800 further comprises the first connecting rope 810, one end of the first connecting rope 810 is connected with the top of the control block 610, and the other end of the first connecting rope 810 is connected with the floating block 400. When the floating block 400 moves downwards, the control block 610 moves upwards, and when the floating block 400 moves upwards, the control block 610 moves downwards under the impact force of water in the water collecting tank 600.

[0061] When the water in the first cavity 320 of the water filtering tank 300 is relatively sufficient, the floating block 400 is relatively close to the top of the water filtering tank 300, at this time, the control block 610 is relatively close to the bottom of the water collecting tank 600 under the impact force of water in the water collecting tank 600, and at this time, the liquid feeding opening 640 is relatively large, and more water can flow out of the water feeding opening at the same time, so that the dripping speed of the dripping head 820 is relatively fast, and then the intermittent water feeding structure 800 feeds water more frequently. When the water in the first cavity 320 of the water filtering tank 300 is less, the floating block 400 moves downwards, at this time, the control block 610 is pulled upwards by the first connecting rope 810 and closes part of the water feeding opening, so that the water flowing out of the water feeding opening per unit time is less, thereby reducing the water feeding frequency of the intermittent water feeding structure 800, and prolonging the use time of rainwater while ensuring the growth of plants.

[0062] In addition, the wedge-shaped block limits the pumping speed of the pumping pipe 500 when the floating block 400 moves downward, which makes the water in the collecting tank 600 move toward the intermittent water supply structure 800 at a slower speed when the pumping pipe 500 moves water into the collecting tank 600 at a slower speed, so that the water in the collecting tank 600 reaches a dynamic balance. In this case, the water level in the collecting tank 600 does not change substantially, so the impact force of the water in the collecting tank 600 on the control block 610 remains substantially unchanged, and the control block 610 is connected to the floating block 400 by the first connecting rope 810, so the force of the control block 610 on the floating block 400 does not change substantially, thereby avoiding ensuring that the floating block 400 receives a substantially constant pulling force from the control block 610 at any height, thereby preventing the floating block 400 from rising or sinking too much.

[0063] Referring to Figure 5 and Figures 10 to 12 In the present embodiment, the collecting tank 600 is provided with a mounting shaft 620 and a pulley 630. The mounting shaft 620 is mounted on the top of the collecting tank 600, and the pulley 630 is rotatably connected to the mounting shaft 620. The inner wall of the pulley 630 is provided with a ratchet 631, and the mounting shaft 620 is provided with a recess 623, a first rotating piece 621 and a first elastic member 622. The first rotating piece 621 is rotatably connected to the mounting shaft 620, and the two ends of the first elastic member 622 are connected to the mounting shaft 620 and the first rotating piece 621, respectively. The first elastic member 622 causes the first rotating piece 621 to have a tendency to rotate outward of the recess 623. When the first rotating piece 621 rotates outward of the recess 623, the first rotating piece 621 cooperates with the ratchet 631 to prevent the pulley 630 from continuing to rotate, and when the first rotating piece 621 returns to the recess 623, the pulley 630 can rotate smoothly relative to the mounting shaft 620. The first connecting rope 810 is wound at least one turn around the pulley 630, so that when the pulley 630 rotates, the first connecting rope 810 must move, and when the pulley 630 does not rotate, the first connecting rope 810 cannot move.

[0064] The second rotating piece 510 and the second connecting rope 520 are arranged in the water suction pipe 500. The first rotating piece 621 is rotationally connected with the bottom wall of the water suction pipe 500. One end of the second connecting rope 520 is connected with the second rotating piece 510, and the other end of the second connecting rope 520 is connected with the first rotating piece 621. When there is no water flowing in the water suction pipe 500, the elastic force of the first elastic piece 622 can make the first rotating piece 621 rotate out of the recess 623, and make the free end of the second rotating piece 510 be raised, at this time, the second rotating piece 510 will cause resistance to the water flowing in the water suction pipe 500. When there is water flowing in the water suction pipe 500, the pressure of the water flow on the second rotating piece 510 will make the free end of the second rotating piece 510 rotate towards the direction of being attached to the bottom wall of the water suction pipe 500, and the second rotating piece 510 can drive the first rotating piece 621 to return to the recess 623 when rotating.

[0065] When there is no water flowing in the water suction pipe 500, the cooperation of the first rotating piece 621 and the ratchet 631 can fix the position of the control block 610; when there is water flowing in the water suction pipe 500, the first rotating piece 621 will be pulled back to the recess 623 under the pressure of the water pressure on the second rotating piece 510, at this time, the pulley 630 can rotate arbitrarily, that is, at this time, the control block 610 can slide up and down.

[0066] The first contact switch and the second contact switch are arranged in the water filtering tank 300, and the first contact switch and the second contact switch are electrically connected with the water suction machine. When the first contact switch is triggered, the water suction machine stops working, and when the second contact switch is triggered, the water suction machine starts working again. The contact piece 410 for cooperating with the first contact switch and the second contact switch is arranged on the floating block 400, and the contact piece 410 is located between the first contact switch and the second contact switch, when the contact piece 410 contacts with the first contact switch or the second contact switch, the first contact switch or the second contact switch can be triggered, and the working state of the water suction machine can be controlled.

[0067] Referring to Figure 6The third elastic member 420 is arranged on the float 400, and a sliding groove is arranged on the float 400 in the height direction of the float 400, and the third elastic member 420 is located in the sliding groove. The contact piece 410 is in sliding connection with the float 400, one end of the contact piece 410 is in sliding connection with the sliding groove, and the two ends of the third elastic member 420 are connected with the float 400 and the contact piece 410 respectively, and the third elastic member 420 enables the contact piece 410 to have a tendency to move upward along the height direction of the float 400. Since the water filtering tank 300 is mainly used for containing rainwater, the water supplement pipe 700 stops working after supplementing a small amount of water, and the remaining water is supplemented by rainwater, thereby saving water resources. Based on the above reasons, the second contact switch is arranged at a lower position, and when rainwater enters the water filtering tank 300, the liquid level continues to rise, and the float 400 also rises together. By arranging the contact piece 410 in a sliding manner through the third elastic member 420, it can be ensured that the contact piece 410 will not damage the second contact switch when the float 400 continues to rise.

[0068] The water supplement pipe 700 is in communication with the water collecting tank 600, the water collecting tank 600 is provided with a water level sensor, the water supplement pipe 700 is provided with a switch valve, the water level sensor is electrically connected with a controller, and the controller is electrically connected with the switch valve. When the water level in the water collecting tank 600 is lower than a preset value in the controller, the controller controls the switch valve to open; when the water level in the water collecting tank 600 is higher than the preset value in the controller, the controller controls the switch valve to close. The water supplement pipe 700 can supplement water to the water collecting tank 600 to ensure that the plants grow normally.

[0069] Based on the above structure, the water filtering tank 300 and the water collecting tank 600 disclosed in the embodiment work as follows:

[0070] When the water level in the first cavity 320 of the water filtering tank 300 is high, the float 400 floats high, at this time, the water pump 500 extracts more water per unit time, and more water flows from the water collecting tank 600 to the dripper 820 per unit time.

[0071] When the water level in the first cavity 320 of the water filtering tank 300 decreases, the water pump 500 extracts less water per unit time, and less water flows from the water collecting tank 600 to the dripper 820 per unit time. When it is necessary to clean the sludge or the water in the water filtering tank 300 is less, the float 400 is lowered to drive the contact piece 410 to contact the first contact switch, at this time, the water pump stops working, and at this time, since the position of the float 400 is lowered to the lowest, the water flowing from the water collecting tank 600 to the dripper 820 per unit time is also the least.

[0072] If the water level in the water collecting tank 600 is lower than the preset water level in the controller during the time when the water pump stops working, the controller controls the switch valve to open and the water collecting tank 600 is replenished with water through the water replenishing pipe 700. If the water pump has restarted working before the water level in the water collecting tank 600 is lowered to the preset water level in the controller, the water replenishing pipe 700 does not need to replenish the water collecting tank 600 with water, thereby saving clean water resources.

[0073] When the water level in the first cavity 320 of the water filtering tank 300 rises again, the float 400 drives the water pumping pipe 500 and the contact piece 410 to gradually rise, and when the contact piece 410 contacts the second contact switch, the controller controls the water pump to restart working, thereby maintaining the balance of the water level in the water collecting tank 600.

[0074] Referring to Figure 2 and Figure 7 , the intermittent water supplying structure 800 comprises a dustproof tank 830, a dripping head 820, a hinged plate 840, a counterweight 850 and a water supplying pipe 860. The top of the dustproof tank 830 is provided with a water inlet, and the bottom of the dustproof tank 830 is provided with a rotating plate 831 which is rotationally connected with the dustproof tank 830. The hinged plate 840 is rotationally connected with the dustproof tank 830, and the first end of the hinged plate 840 is provided with a water receiving disc which is located below the water inlet. One end of the water supplying pipe 860 is located below the first end of the hinged plate 840, and the other end of the water supplying pipe 860 extends to the first end of the rotating plate 831, and the rotating plate 831 is rotated to open or close the water supplying pipe 860. The counterweight 850 is installed at the second end of the hinged plate 840, and the dripping head 820 is installed at the water inlet and communicates with the water collecting tank 600. When the water in the water collecting tank 600 is sufficient, the dripping head 820 can drip water at a constant speed towards the water receiving disc, and the water receiving disc and the counterweight 850 are located at the two ends of the hinged plate 840 respectively, and when the water in the water receiving disc is less or none, the first end of the hinged plate 840 is lifted upwards by the counterweight 850, and the water dripping into the water receiving disc from the dripping head 820 is temporarily stored; when a certain amount of water is gathered in the water receiving disc, the first end of the hinged plate 840 can lift the second end thereof installed with the counterweight 850, and at this time, the water receiving disc is inclined and the water in the water receiving disc flows into the water supplying pipe 860 below, and the water flowing along the water supplying pipe 860 exerts pressure on the rotating plate 831, so that the rotating plate 831 is rotated and the water supplying pipe 860 is opened, and at this time, the water can flow out of the dustproof tank 830 and flow to the plants. Since the dust in the drought area is large, the dustproof tank 830 can effectively avoid the dust directly falling into the water receiving disc, so that a large amount of dust can be avoided from being splashed to the plants when the plants are watered, thereby avoiding affecting the growth of the plants.

[0075] Referring to Figure 8 and Figure 9The water receiving tray comprises a first side wall 871, a second side wall 872, a third side wall 873 and a fourth side wall 874. The first side wall 871 is fixedly connected with the dustproof box 830, and the second side wall 872, the third side wall 873 and the fourth side wall 874 are all installed on the first end of the flap plate 840. The second side wall 872, the third side wall 873 and the fourth side wall 874 enclose a "concave" shape. When the flap plate 840 abuts against the first side wall 871, the first side wall 871, the second side wall 872, the third side wall 873 and the fourth side wall 874 enclose a water receiving cavity 870 for receiving water, and the first side wall 871 is located on the side close to the rotating plate 831. The water receiving tray is divided into the first side wall 871 fixed on the dustproof box 830 and the second side wall 872, the third side wall 873 and the fourth side wall 874 which can rotate with the flap plate 840. On the one hand, the first side wall 871 can be used to quickly position the flap plate 840, so as to facilitate the water receiving tray to be just stopped below the dripper 820. On the other hand, the first side wall 871 does not rotate with the flap plate 840, which can ensure that the water in the water receiving tray can all and quickly enter the water delivery pipe 860 when the first end of the flap plate 840 rotates downward.

[0076] Referring to Figures 7 to 9The intermittent water feeding structure 800 further comprises a limiting block 832. The limiting block 832 is in sliding connection with the dustproof box 830, and the limiting block 832 is in sliding connection with the second end of the rotating plate 831. The sliding direction of the limiting block 832 relative to the dustproof box 830 is perpendicular to the sliding direction of the limiting block 832 relative to the rotating plate 831. When the rotating plate 831 rotates, the limiting block 832 can be driven to slide relative to the dustproof box 830. The side of the flap plate 840 facing the rotating plate 831 is provided with a limiting groove 841 for cooperating with the limiting block 832, and an inclined surface is arranged at the first end of the flap plate 840. During the working process of the intermittent water feeding structure 800, when the rotating plate 831 closes the water feeding pipe 860, the limiting block 832 is driven away from the limiting groove 841, and at this time the flap plate 840 can rotate freely. When a certain amount of water accumulates in the water receiving tray, the first end of the flap plate 840 drops and pours the water into the water feeding pipe 860, at this time the first end of the rotating plate 831 rotates outward under the thrust of the water and opens the water feeding pipe 860, and the second end of the rotating plate 831 rotates towards the flap plate 840 and drives the limiting block 832 to move towards the flap plate 840. When the water in the water receiving tray is poured out, the first end of the flap plate 840 rotates upward under the action of the counterweight 850, and then the inclined surface on the flap plate 840 contacts the limiting block 832 and drives the limiting block 832 to move backward. At this time, the rotating plate 831 will temporarily close the water feeding pipe 860 again, until the flap plate 840 rotates to the horizontal position, the water in the water feeding pipe 860 drives the rotating plate 831 to rotate again and makes the limiting block 832 clamped in the limiting groove 841 on the flap plate 840, at this time the flap plate 840 cannot continue to rotate. Finally, when all the water in the water feeding pipe 860 flows out, the rotating plate 831 returns to the vertical state, at this time the rotating plate 831 re-closes the water feeding pipe 860 and can drive the limiting block 832 to move out of the range of the limiting groove 841, so that the flap plate 840 can smoothly rotate next time. The limiting block 832 and the limiting groove 841 are mainly used for quickly fixing the flap plate 840. After the water in the water receiving tray is poured out, when the flap plate 840 rotates under the action of the counterweight 850, due to the fast rotating speed of the flap plate 840, the flap plate 840 may collide with the first side wall 871 and rebound after contacting the first side wall 871, and may rebound multiple times. This situation causes serious wear of the flap plate 840 and the first side wall 871. The limiting block 832 and the limiting groove 841 can quickly help the flap plate 840 to be positioned and stopped, thereby reducing the wear of the flap plate 840 and effectively prolonging the service life of the flap plate 840 and the first side wall 871.

[0077] In order to ensure that the rotating plate 831 can keep the vertical state in the free state, the rotating axis of the rotating plate 831 is arranged to be higher, so that the length of the first end of the rotating plate 831 is greater than the length of the second end, so that the weight of the first end of the rotating plate 831 is greater than the weight of the second end, and then the rotating plate 831 can keep the vertical state under the action of its own gravity.

[0078] The preferred embodiments of the present application have been described above, but the present application is not limited to the above. Any modifications, equivalent replacements, improvements and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
