Description

Technical Field

[0001] The present invention relates to a soil and water conservation soil-fixing system, belonging to the technical field of environmental governance, and particularly to a soil and water conservation soil-fixing system for preventing and controlling wind erosion desertification areas. Background Art

[0002] In desert areas, the climate is dry, precipitation is scarce, and the vegetation coverage is low, resulting in poor soil fertility and susceptibility to wind erosion and desertification. Greening in desert areas usually requires a large amount of water to be transported over long distances for irrigation, which is costly and inefficient.

[0003] The existing technology mainly focuses on building water storage facilities and using drip irrigation to supplement the soil moisture in the vegetation area to ensure the growth needs of the vegetation. However, the existing drip irrigation system has poor flexibility and a small coverage area. When in use, it can only cover a very small area and will not automatically change the wetting effect on the soil with the change of the wind direction, resulting in poor pertinence and almost no improvement effect on the soil in the long run.

[0004] Therefore, those skilled in the art have proposed a soil and water conservation soil-fixing system for preventing and controlling wind erosion desertification areas, designed an irrigation device that can automatically adjust the wetting degree of the surrounding soil with the change of the wind direction, which can better treat the soil in the desertification area and is conducive to saving water resources. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a soil and water conservation soil-fixing system for preventing and controlling wind erosion desertification areas. A flow rate adjustment mechanism is provided on the water delivery pipe rack to automatically associate and control the irrigation method and range of the drip irrigation nozzles following the changes in wind direction and wind speed. The wind direction monitoring rod can monitor the external wind direction and wind speed in real time, adjust the water pressure change in the water delivery pipe rack through the deflection of the wind direction monitoring rod, and cooperate with adjusting the diameter of the drip irrigation nozzles to realize the automatic switching between the drip irrigation and spraying modes of the drip irrigation nozzles, and then combine the rotation of the guide plate to irrigate the soil within a certain range.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A soil and water conservation soil-fixing system for preventing and controlling wind erosion desertification areas, including a water delivery pipe rack, drip irrigation nozzles, and ground piles. The water delivery pipe rack transports water to the drip irrigation nozzles for irrigation, and the ground piles are used for fixed installation of the water delivery pipe rack.

[0007] However, the existing drip irrigation systems can only passively irrigate a fixed range of soil according to the set flow rate. Such systems require manual monitoring and intervention control, and cannot control the irrigation process in detail and actively. Since the wind direction and wind speed in desertification areas change in real time, and the evaporation rates of lands with different terrains are different, problems such as uneven irrigation and water resource waste will occur if a fixed mode is used for irrigation on a large scale. Therefore, those skilled in the art have proposed improvements to the existing irrigation systems, hoping that the irrigation systems can automatically adjust the irrigation mode according to real-time monitoring, which is more conducive to water-saving irrigation operations in desertification areas.

[0008] A wind direction monitoring rod is inserted and arranged at the top of the water delivery pipe rack, which can automatically deflect the angle following the wind speed and wind direction of the environment. A flow rate adjusting mechanism is associated with the wind direction monitoring rod inside the water delivery pipe rack. Through the deflection of the wind direction monitoring rod, the flow rate adjusting mechanism is linked, so as to realize automatic irrigation adjustment according to the changes of the environment.

[0009] The flow rate adjusting mechanism includes a flow rate adjusting plate. The flow rate adjusting plate is arranged inside the water delivery pipe rack. When the wind direction monitoring rod deflects, the flow rate adjusting plate correspondingly makes a carry, covering or enlarging the nozzle diameter of the drip irrigation nozzle.

[0010] A deflector is arranged on the side of the water delivery pipe rack and at the position of the drip irrigation nozzle. The deflection of the wind direction monitoring rod drives the deflector to rotate, guiding the water flowing out of the drip irrigation nozzle to one side, so that the water flows along the deflector, covering the soil in the extending direction and range of the deflector. The irrigation range is larger than that of the existing drip irrigation system. It should be noted that the deflector needs to be suspended and not blocked.

[0011] Preferably, a pressure reducing valve is arranged inside the water delivery pipe rack, and a spring is arranged between the wind direction monitoring rod and the pressure reducing valve. When the wind direction monitoring rod deflects, it drives the pressure reducing valve to rotate to adjust the water pressure inside the water delivery pipe rack. The change of the water pressure combined with the change of the nozzle diameter of the drip irrigation nozzle realizes the change between two modes of spraying and drip irrigation.

[0012] A tightening mechanism for the wind direction monitoring rod is also arranged on the side of the water delivery pipe rack. Through this tightening mechanism, the tightness of the wind direction monitoring rod can be adjusted to avoid affecting the adjustment accuracy of the equipment due to the attenuation of the elastic coefficient of the elastic component.

[0013] Preferably, the tightening mechanism includes a threaded cylinder. The threaded cylinder is fixed on the side wall of the water delivery pipe rack, and the threaded cylinder is composed of a plurality of arc-shaped plates distributed in a ring shape.

[0014] A mounting tube is inserted into the inner side of the threaded tube, and the wind direction monitoring rod is inserted into the inner side of the mounting tube and rotatably connected thereto. The mounting angle of the mounting tube can be adjusted arbitrarily inside the threaded tube, and the wind direction monitoring rod can also rotate inside the mounting tube according to changes in wind direction.

[0015] Preferably, the outer wall of the threaded barrel is provided with threads, and a fastening nut is sleeved on the side of the threaded barrel through an external thread, and the fastening nut can be rotated to close the multiple arc plates to clamp and position the installation barrel inserted into the inner side of the threaded barrel.

[0016] The mounting tube extends into the side of one end of the inner side of the water supply pipe rack and is fixedly connected to a mounting sleeve. One end of the spring extends into the inner side of the mounting sleeve and is fixed. The spring is pressed against the wind direction monitoring rod through the mounting sleeve to prevent the compressed spring from changing the direction of the elastic force and affecting the regulating effect of the wind direction monitoring rod on the flow rate regulating mechanism.

[0017] Preferably, the outer wall of the mounting tube is provided with anti-slip grooves, which cooperate with the locked threaded tube to prevent the mounting tube on which the spring is tightly mounted from deflecting.

[0018] A push rod is fixedly connected to the side of the wind direction monitoring rod, and the push rod is fixedly connected to an end of the spring away from the mounting sleeve. The push rod corresponds to the wind direction monitoring rod and the mounting sleeve respectively, thereby facilitating the association of the wind direction monitoring rod and the flow rate regulating mechanism through the spring.

[0019] Preferably, the underground pile includes a lifting rod, which is fixedly connected to the water pipe rack. The side of the lifting rod is sleeved with a foundation pile, which is nailed into the ground to help install the water pipe rack. The lifting rod slidably arranged at one end of the foundation pile facilitates the adjustment of the installation height of the water pipe rack, and facilitates the adjustment and installation of the water pipe rack at a certain height from the ground.

[0020] Preferably, a percolation port is provided through the side wall of the water supply pipe rack, and the drip irrigation nozzle is fixed to the side of the water supply pipe rack through the percolation port. The diameter of the nozzle of the drip irrigation nozzle is determined by the change in the opening of the percolation port.

[0021] The inner wall of the water supply pipe rack is fixedly connected with a slide rail, and the flow rate adjustment plate is slidably arranged on the inner side of the water supply pipe rack through the slide rail. As the wind direction monitoring rod is deflected, the flow rate adjustment plate is driven to move along the slide rail. The moved flow rate adjustment plate adjusts the opening of the infiltration port, and the mode switching between drip irrigation and atomization is realized in conjunction with the water pressure change in the water supply pipe rack.

[0022] Preferably, a rack is fixedly connected to the end of the flow rate regulating plate, a driving gear is fixedly sleeved on the side of the wind direction monitoring rod, and the flow rate regulating plate is meshingly connected to the wind direction monitoring rod via the rack.

[0023] Preferably, a percolation groove is formed in the side surface of the flow rate adjusting plate corresponding to the drip irrigation nozzle. As the flow rate adjusting plate advances, the coincidence degree between the percolation groove formed in the side surface of the flow rate adjusting plate and the percolation port bracket on the side wall of the water supply pipe rack changes, and thus the nozzle diameter of the drip irrigation nozzle also changes accordingly.

[0024] A sealing gasket is arranged on the side surface of the flow rate adjusting plate. As the flow rate adjusting plate advances, the percolation port is covered by the coincidence of the flow rate adjusting plate, and the sealing effect of the water supply pipe rack is ensured through the sealing gasket to prevent evaporation and leakage.

[0025] Preferably, an installation collar is rotatably arranged on the side wall of the water supply pipe rack. The installation collar is installed with the drip irrigation nozzle as the rotation axis. The guide plate is obliquely arranged below the drip irrigation nozzle through the installation collar. A connecting rod is fixed between the installation collar and the guide plate. As the wind direction monitoring rod deflects, the guide plate rotates accordingly. The liquid dripping from the drip irrigation nozzle flows along the inclined direction of the guide plate and irrigates the land within the range along the edge of the guide plate.

[0026] The present invention discloses a soil and water conservation and soil fixation system for preventing and controlling wind erosion desertification areas, and its beneficial effects are as follows:

[0027] 1. This soil and water conservation and soil fixation system for preventing and controlling wind erosion desertification areas is different from the general drip irrigation systems in the prior art. A wind direction monitoring rod that can sense the changes in wind speed and wind direction in the environment is arranged on the water supply pipe rack. According to the changes in wind speed, the flow rate adjusting mechanism and the pressure reducing valve are driven in real-time association. The changes in wind speed and wind direction drive the flow rate adjusting plate to advance to different degrees, thereby changing the opening degree of the drip irrigation nozzle. At the same time, the deflection of the wind direction monitoring rod drives the guide plate to rotate, changing the irrigation range and flow rate. Combined with the adjustment of the water pressure in the water supply pipe rack by the pressure reducing valve, the control of the drip irrigation flow rate is realized, and even two different usage modes of drip irrigation and spraying can be switched.

[0028] 2. In this soil and water conservation and soil fixation system for preventing and controlling wind erosion desertification areas, the wind direction monitoring rod deflects with the wind direction in the environment. In order to associate the changes in wind direction and wind speed in the environment with the irrigation method of the equipment, a threaded cylinder is fixed on the side surface of the water supply pipe rack. The installation cylinder is inserted through the threaded cylinder. When the wind direction changes, the wind direction monitoring rod deflects. The deflected wind direction monitoring rod pushes the pressure reducing valve and the flow rate adjusting plate, changing the water pressure in the water supply pipe rack and the nozzle diameter of the drip irrigation nozzle. Thus, the flow rate at the drip irrigation nozzle changes accordingly, and the corresponding water pressure change automatically switches the drip irrigation and sprinkler irrigation modes at the drip irrigation nozzle, making the irrigation mode more automated and modular.

[0029] 3. For the soil and water conservation and soil fixation system in the area for preventing and controlling wind erosion desertification, percolation openings are provided on the side wall of the water delivery pipe rack for installing drip irrigation nozzles, and percolation grooves are also provided through the side surface of the flow rate adjustment plate. The overlapping part of the percolation opening and the percolation groove determines the opening degree of the nozzle of the drip irrigation nozzle. Combining with the control of the water pressure in the water delivery pipe rack, not only can the liquid flow rate at the drip irrigation nozzle be controlled, but also the two use modes of drip irrigation and sprinkler irrigation of the drip irrigation nozzle can be further switched, so as to automatically switch the irrigation mode of the equipment in different environments and intelligently irrigate the soil in the desertification area.

[0030] 4. For the soil and water conservation and soil fixation system in the area for preventing and controlling wind erosion desertification, a diversion plate is rotatably arranged below the drip irrigation nozzle through an installation collar. As the wind direction adjusting rod rotates, the diversion plate rotates accordingly. The liquid dripping from the drip irrigation nozzle flows along the diversion plate and irrigates the soil in this direction as the liquid flows, with a larger irrigation range than the existing drip irrigation system.

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0042] The embodiments of the present invention disclose a soil and water conservation and soil fixation system for preventing and controlling wind erosion desertification areas;

[0043] According to the atta Figure 1 As shown, it includes a water supply pipe rack 1, a drip irrigation nozzle 2 and a ground pile 3. The water supply pipe rack 1 conveys water to the drip irrigation nozzle 2 for irrigation, and the ground pile 3 fixedly installs the water supply pipe rack 1.

[0044] However, the existing drip irrigation system can only passively irrigate a fixed range of soil according to the set flow rate. This system requires manual monitoring and intervention control, and cannot control the irrigation process in detail and actively. Moreover, the wind direction and wind speed in desertification areas change in real time, and the evaporation amounts of lands with different terrains are different. If a fixed mode is used for irrigation in a large range, problems such as uneven irrigation and water resource waste will occur. Therefore, those skilled in the art have proposed improvements to the existing irrigation system, hoping that the irrigation system can automatically adjust the irrigation mode according to real-time monitoring, which is more conducive to water-saving irrigation operations in desertification areas.

[0045] A wind direction monitoring rod 4 is inserted and arranged at the top of the water supply pipe rack 1, which can automatically deflect the angle following the wind speed and wind direction of the environment. A flow rate adjusting mechanism 5 is associated with the wind direction monitoring rod 4 inside the water supply pipe rack 1. By the deflection of the wind direction monitoring rod 4 to drive the flow rate adjusting mechanism 5, the automatic irrigation adjustment according to the change of the environment is realized.

[0046] According to the atta Figure 2As shown, a pressure reducing valve 6 is arranged on the inner side of the water supply pipe rack 1, and a spring 7 is arranged between the wind direction monitoring rod 4 and the pressure reducing valve 6. When the wind direction monitoring rod 4 is deflected, the pressure reducing valve 6 is driven to rotate to adjust the water pressure in the water supply pipe rack 1. The change of water pressure combined with the change of nozzle diameter of the drip irrigation nozzle 2 realizes the change of the two modes of spray and drip irrigation.

[0047] According to the attached Figure 3 As shown, a tightening mechanism for the wind direction monitoring rod 4 is also provided on the side of the water supply pipe rack 1, through which the tightness of the wind direction monitoring rod 4 can be adjusted to avoid affecting the adjustment accuracy of the equipment due to the attenuation of the elastic coefficient of the elastic component.

[0048] Preferably, the tightening mechanism comprises a threaded barrel 8, which is fixed on the side wall of the water pipe rack 1, and the threaded barrel 8 is composed of a plurality of arc-shaped plates distributed in a ring shape.

[0049] A mounting tube 9 is inserted into the inner side of the threaded tube 8, and the wind direction monitoring rod 4 is inserted into the inner side of the mounting tube 9 and rotatably connected thereto. The mounting angle of the mounting tube 9 can be adjusted arbitrarily inside the threaded tube 8, and the wind direction monitoring rod 4 can also rotate inside the mounting tube 9 according to changes in wind direction.

[0050] Preferably, the outer wall of the threaded barrel 8 is provided with threads, and the side of the threaded barrel 8 is sleeved with a fastening nut 10 through an external thread. By rotating the fastening nut 10, multiple arc plates can be retracted to clamp and position the installation barrel 9 inserted into the inner side of the threaded barrel 8.

[0051] According to the attached Figure 4 As shown, the mounting tube 9 extends into the side of one end of the inner side of the water supply pipe rack 1 and is fixedly connected with a mounting sleeve 11. One end of the spring 7 extends into the inner side of the mounting sleeve 11 and is fixed. The spring 7 is pressed against the wind direction monitoring rod 4 through the mounting sleeve 11 to prevent the compressed spring 7 from changing the direction of the elastic force and affecting the regulating effect of the wind direction monitoring rod 4 on the flow rate regulating mechanism 5.

[0052] Preferably, the outer wall of the installation tube 9 is provided with anti-slip grooves 12, which cooperate with the locked threaded tube 8 to prevent the installation tube 9 on which the spring 7 is installed from deflecting.

[0053] A push rod 13 is fixedly connected to the side of the wind direction monitoring rod 4, and the push rod 13 is fixedly connected to the end of the spring 7 away from the mounting sleeve 11. The push rod 13 corresponds to the wind direction monitoring rod 4 and the mounting tube 9 respectively, thereby facilitating the association of the wind direction monitoring rod 4 and the flow rate regulating mechanism 5 through the spring 7.

[0054] According to the attached Figure 5As shown, the ground pile 3 includes a lifting rod 301. The lifting rod 301 is fixedly connected to the water supply pipe rack 1. A base pile 302 is sleeved on the side of the lifting rod 301. The base pile 302 is nailed into the ground to assist in the installation of the water supply pipe rack 1. The lifting rod 301 slidably arranged at one end of the base pile 302 facilitates the adjustment of the installation height of the water supply pipe rack 1 and is convenient for the adjustment and installation of the water supply pipe rack 1 at a certain height from the ground.

[0055] According to the appendix Figure 6 and the appendix Figure 7 As shown, the flow rate adjusting mechanism 5 includes a flow rate adjusting plate 501. The flow rate adjusting plate 501 is arranged inside the water supply pipe rack 1. When the wind direction monitoring rod 4 deflects, the flow rate adjusting plate 501 makes a corresponding movement, covering or magnifying the nozzle diameter of the drip irrigation nozzle 2.

[0056] A deflector plate 502 is arranged on the side of the water supply pipe rack 1 at the position of the drip irrigation nozzle 2. The deflection of the wind direction monitoring rod 4 drives the deflector plate 502 to rotate, guiding the water flowing out of the drip irrigation nozzle 2 to one side, so that the water flows along the deflector plate 502, covering the soil in the extending direction and range of the deflector plate 502. The irrigation range is larger than that of the existing drip irrigation system. It should be noted that the deflector plate 502 needs to be suspended and not blocked.

[0057] A percolation port 14 is penetrated through the side wall of the water supply pipe rack 1. The drip irrigation nozzle 2 is fixed to the side of the water supply pipe rack 1 through the percolation port 14. The diameter of the nozzle of the drip irrigation nozzle 2 is determined by the change in the opening degree of the percolation port 14.

[0058] A slide rail 15 is fixedly connected to the inner wall of the water supply pipe rack 1. The flow rate adjusting plate 501 is slidably arranged inside the water supply pipe rack 1 through the slide rail 15. As the wind direction monitoring rod 4 deflects, it drives the flow rate adjusting plate 501 to move along the slide rail 15. The advancing flow rate adjusting plate 501 adjusts the opening degree of the percolation port 14, and cooperates with the change in the water pressure inside the water supply pipe rack 1 to realize the mode switching between drip irrigation and atomization.

[0059] Preferably, a rack 16 is fixedly connected to the end of the flow rate adjusting plate 501. A driving gear 17 is fixedly sleeved on the side of the wind direction monitoring rod 4. The flow rate adjusting plate 501 is meshed with the wind direction monitoring rod 4 through the rack 16.

[0060] Preferably, a percolation groove 18 is formed on the side of the flow rate adjusting plate 501 corresponding to the drip irrigation nozzle 2. As the flow rate adjusting plate 501 advances, the coincidence degree between the percolation groove 18 formed on the side of the flow rate adjusting plate 501 and the percolation port 14 on the side wall of the water supply pipe rack 1 changes, and then the nozzle diameter of the drip irrigation nozzle 2 also changes accordingly.

[0061] A sealing gasket 19 is provided on the side of the flow rate regulating plate 501. As the flow rate regulating plate 501 advances, the percolation port 14 is covered by the flow rate regulating plate 501, and the sealing effect of the water supply pipe rack 1 is ensured through the sealing gasket 19 to prevent evaporation and leakage.

[0062] According to the attached Figure 8 As shown, an installation collar 20 is rotatably provided on the side wall of the water supply pipe rack 1. The installation collar 20 is installed with the drip irrigation nozzle 2 as the rotation axis. The deflector 502 is obliquely arranged below the drip irrigation nozzle 2 through the installation collar 20. A connecting rod 21 is fixed between the installation collar 20 and the deflector 502. As the wind direction monitoring rod 4 deflects, the deflector 502 rotates accordingly. The liquid dripping from the drip irrigation nozzle 2 flows along the inclined direction of the deflector 502 and irrigates the land within the range along the edge of the deflector 502.

[0063] This soil and water conservation and soil fixation system for preventing wind erosion desertification areas is different from the general drip irrigation systems in the prior art. A wind direction monitoring rod 4 that can sense the changes in wind speed and wind direction in the environment is provided on the water supply pipe rack 1. The flow rate regulating mechanism 5 and the pressure reducing valve 6 are driven in real-time association according to the wind speed changes. The changes in wind speed and wind direction drive the flow rate regulating plate 501 to advance to different degrees, thereby changing the opening degree of the drip irrigation nozzle 2. At the same time, the deflection of the wind direction monitoring rod 4 drives the deflector 502 to rotate, changing the irrigation range and flow rate. Combined with the regulation of the water pressure in the water supply pipe rack 1 by the pressure reducing valve 6, the control of the drip irrigation flow rate is realized, and even two different usage modes of drip irrigation and spraying can be switched.

[0064] Further, the wind direction monitoring rod 4 deflects with the wind direction in the environment. In order to associate the changes in wind direction and wind speed in the environment with the irrigation method of the equipment, a threaded cylinder 8 is fixed on the side of the water supply pipe rack 1. The installation cylinder 9 is inserted through the threaded cylinder 8. When the wind direction changes, the wind direction monitoring rod 4 deflects. The deflected wind direction monitoring rod 4 pushes the pressure reducing valve 6 and the flow rate regulating plate 501, changing the water pressure in the water supply pipe rack 1 and the nozzle diameter of the drip irrigation nozzle 2. Consequently, the flow rate at the drip irrigation nozzle 2 changes accordingly, and the corresponding water pressure change automatically switches the drip irrigation and sprinkler irrigation modes at the drip irrigation nozzle 2, making the irrigation mode more automated and modular.

[0065] Furthermore, the side wall of the water supply pipe rack 1 is provided with a percolation port 14 for installing the drip irrigation nozzle 2, and a percolation groove 18 is also penetrated on the side of the flow rate regulating plate 501. The overlapping part of the percolation port 14 and the percolation groove 18 determines the nozzle opening degree of the drip irrigation nozzle 2. Combined with the control of the water pressure in the water supply pipe rack 1, not only can the liquid flow rate at the drip irrigation nozzle 2 be controlled, but also the two usage modes of drip irrigation and sprinkler irrigation of the drip irrigation nozzle 2 can be further switched, and then the irrigation mode of the equipment can be automatically switched in different environments, and the soil can be irrigated intelligently in desertification areas.

[0066] Further, a diversion plate 502 is rotatably arranged below the drip irrigation nozzle 2 through a mounting collar 20. As the wind direction monitoring rod 4 rotates, the diversion plate 502 rotates accordingly. The liquid dripping from the drip irrigation nozzle 2 flows along the diversion plate 502, and the soil in this direction is irrigated as the liquid flows, with a larger irrigation range than that of the existing drip irrigation system.

[0067] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
