Description

Technical Field

[0001] The present application relates to the technical field of saline-alkali land management, and in particular to a saline-alkali land water collection irrigation and drainage ditch. Background Art

[0002] Saline-alkali land refers to land with excessively high salt and alkaline content in the soil, which has an adverse effect on the growth of most plants. The salt in this type of soil mainly includes sodium chloride, sodium sulfate, etc., while the alkaline substances mainly come from carbonates or heavy phosphates in the soil.

[0003] At present, water-based salt control is one of the effective methods for managing saline-alkali land. It uses irrigation, flood diversion and silt release to continuously wash and remove salt from the soil. Combining underground pipe salt drainage technology and strict control of groundwater levels can prevent soil salt from returning. However, most saline-alkali areas have a shortage of water resources, especially freshwater resources, which are insufficient to support the implementation of water-based salt control technologies. Although rainwater is a very important and low-cost freshwater resource, and the collection and utilization of rainwater is an important measure to solve the problem of freshwater salt leaching / salt control in saline-alkali land, the collection and storage of rainwater has become a key factor restricting the scientific utilization of rainwater resources. Summary of the invention

[0004] In order to improve the collection and utilization of rainwater and provide necessary fresh water resources for saline-alkali land, the present application provides a saline-alkali land water collection irrigation and drainage ditch.

The rain-collecting irrigation mechanism has a rain-collecting mode, a natural irrigation mode and a strong irrigation mode. When it rains, the rain-collecting irrigation mechanism is in the rain-collecting mode, and the rain-collecting component is started to collect rainwater into the water collection ditch. When there is sufficient water in the water collection ditch, the rain-collecting irrigation mechanism can be in the natural irrigation mode, and the primary irrigation component is started. When the rain-collecting irrigation mechanism is in the strong irrigation mode, the secondary irrigation component is started.

[0006] By adopting the above technical solution, when it rains, the rainwater collection irrigation mechanism switches to the rainwater collection mode, the rainwater collection component is started, and rainwater is collected through the bracket and rainwater collection component on the top of the ditch and temporarily stored in the water collection ditch; when the rainwater storage in the water collection ditch is sufficient, the rainwater collection irrigation mechanism can be in the natural irrigation mode, the first-level irrigation component is started, and the saline-alkali land is irrigated or rinsed to remove the salt in the soil; when the rainwater storage in the water collection ditch drops to half or less, the rainwater collection irrigation mechanism can be switched to the strong irrigation mode, and the second-level irrigation component is started to use the remaining water in the water collection ditch to continue to irrigate the saline-alkali land or leaching; wherein, through the rainwater collection mode of the rainwater collection irrigation mechanism, rainwater resources are effectively collected and utilized, the problem of shortage of freshwater resources in saline-alkali areas is solved, necessary freshwater resources are provided for saline-alkali land, and the implementation of water-based salt control technology is supported. In addition, the natural irrigation mode, strong irrigation mode and concealed pipe salt drainage technology of the rainwater collection irrigation mechanism are used to effectively remove the salt in the saline-alkali land, prevent soil salt return, and improve soil structure and quality. At the same time, the bracket adopts a modular detachable connection setting, so that the local rainwater collection irrigation mechanism can be quickly modularly repaired or replaced after damage, reducing maintenance costs and time.

[0007] Optionally, the rain collection component includes: A fixed cover plate is fixedly mounted on the top of the bracket, and a plurality of fixed cover plates are provided, and the plurality of fixed cover plates are spaced apart and distributed along the length direction of the water collecting ditch; There are multiple movable plate groups, which are also spaced apart along the length of the water collecting ditch, and the multiple movable plate groups are staggered with the multiple fixed cover plates, and each of the movable plate groups includes two rain collecting plates symmetrically hinged on the bracket; The opening and closing component is arranged between two rain collecting plates in the same movable plate group, and is used to drive the two rain collecting plates to open or close synchronously.

[0008] By adopting the above technical solution, when it rains, the rainwater collection irrigation mechanism needs to switch to the rainwater collection mode. First, the two rainwater collection plates are driven to open synchronously through the opening and closing components. After the rainwater collection plates are opened, a rainwater collection area is formed, and the rainwater flows into the water collection ditch under the guidance of the opened rainwater collection plates; when the rain stops, the rainwater collection plates are closed through the opening and closing components, so that the top of the water collection ditch is in a closed state to prevent water evaporation or impurities from entering on non-rainy days; wherein the fixed cover plate and the movable plate group are spaced along the length direction of the water collection ditch to form an alternating opening and closing structure, which cooperates with the opening and closing setting of the rainwater collection plates, not only realizing the efficient collection of rainwater and ensuring the full utilization of rainwater resources, but also ensuring the stability of the entire rainwater collection assembly, reducing the evaporation of water or the entry of impurities and pollutants in the water collection ditch on non-rainy days, and maintaining the cleanliness and water quality of the water collection ditch.

[0009] Optionally, the opening and closing component includes: There are two rotating shafts, which correspond to the two rain collecting plates one by one.

A driving motor is also arranged at one end of the worm.

[0010] By adopting the above technical solution, when it is necessary to open the rain collecting plate, the driving motor is first started, and the driving motor drives the worm to rotate. The worm drives the driving shaft to start rotating by meshing with the worm wheel. The rotation of the driving shaft drives the driving gear to rotate. The driving gear meshes with the two racks to make the two racks move in opposite directions. Then the rack drives the two rotating shafts to rotate synchronously by meshing with the driven gear. The rotation of the rotating shaft drives the rain collecting plate to open and form a rainwater collection area. When it is necessary to close the rain collecting plate, the driving motor is started in the reverse direction. Through the above reverse process, the two rain collecting plates are closed synchronously, and the closed state of the top of the water collecting ditch can be restored. Among them, through the cooperation of the worm gear, gear, rack, etc., the precise control and synchronous opening and closing of the rain collecting plate are realized, ensuring the convenience and efficiency of rainwater collection. Due to the self-locking characteristics of the worm gear, the energy consumption of the rain collecting plate in the open and closed state is reduced, and the operating cost of the rain collecting assembly is reduced.

[0014] By adopting the above technical solution, when the raindrop sensor detects raindrops, it will send out a detection signal. After receiving the detection signal, the controller determines whether it is in a raining state. The controller sends a control signal to the drive motor according to a preset program. When the drive motor receives the control signal, it starts and drives the opening and closing components to operate, so that the rain collecting plate is expanded to the outside of the ditch and starts to collect rainwater; when the rain stops, the controller determines that the rainfall is over, and the controller sends a closing signal to the drive motor, and the drive motor starts in reverse to close the rain collecting plate and restore the closed state of the top of the ditch; the rain collecting component can be automatically started according to the rainfall conditions, thereby realizing the intelligent and automatic control of the rain collecting component, reducing human intervention, and ensuring the timeliness and efficiency of rainwater collection, thereby improving the utilization rate of rainwater resources.

[0015] Optionally, the sides of two rain collecting plates in the same movable plate group that are close to each other are arranged in an inclined surface, and the two inclined surfaces can fit each other.

[0016] By adopting the above technical solution, when the rain collecting plate needs to be closed, as the rain collecting plate moves, the two inclined surfaces gradually approach and finally fit together to form a flat and tight sealing surface, thereby further reducing water evaporation on non-rainy days, while preventing rainwater or foreign objects from entering the drainage ditch, thereby improving the dustproof ability of the system.

[0021] Optionally, the secondary irrigation assembly includes: An irrigation pipe is arranged in the water collecting ditch, wherein one end of the irrigation pipe is located outside the water collecting ditch and the other end is located at the bottom wall of the water collecting ditch; The water pump is arranged on the irrigation pipe and connected to the battery.

[0022] By adopting the above technical solution, when the water level in the ditch drops to half or lower and the first-level irrigation component can no longer drain water, the water pump can be started to draw water from one end of the irrigation pipe on the bottom wall of the ditch to continue irrigating or washing the saline-alkali land; the water pump can also be powered by a battery to reduce dependence on traditional electricity and reduce energy consumption.

[0023] Optionally, an impermeable cloth is laid on the inner wall of the water collecting ditch, and a concealed pipe is buried under the bottom wall of the water collecting ditch, and the impermeable cloth is located above the concealed pipe.

[0024] By adopting the above technical scheme, the salt drainage effect of the concealed pipe can be radiated to a certain area of ​​the saline-alkali land. After the drainage ditch is excavated, the concealed pipe can be pre-buried under the drainage ditch, which is convenient for the laying of the concealed pipe, reduces the secondary excavation when burying the concealed pipe in the saline-alkali land, and reduces the construction volume; and the inner wall of the drainage ditch is laid with anti-seepage cloth to prevent the water in the drainage ditch from penetrating into the concealed pipe or soil below, ensuring that the normal salt drainage function of the concealed pipe is not affected by the water in the drainage ditch.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-Figure 6 This application is described in further detail.

[0029] The present application embodiment discloses a saline-alkali land water collection irrigation and drainage ditch. Figure 1-Figure 3The saline-alkali land water collection irrigation and drainage dual-purpose ditch includes a plurality of water collection ditches 1 arranged at intervals in the saline-alkali land, and a bracket 2 is detachably connected to the top of the water collection ditch 1, wherein the bracket 2 is spliced ​​from multiple sections, and a plug-in slot 11 is provided on the top of the water collection ditch 1 along the height direction, and the bracket 2 is plugged into the plug-in slot 11. A rain collection irrigation mechanism 3 is arranged on the bracket 2, and the rain collection irrigation mechanism 3 includes a rain collection component 31, a primary irrigation component 32, and a secondary irrigation component 33; wherein the rain collection irrigation mechanism 3 has a rain collection mode, a natural irrigation mode, and a strong irrigation mode. When it rains, the rain collection irrigation mechanism 3 is in the rain collection mode, and the rain collection component 31 starts to collect rainwater into the water collection ditch 1. When there is sufficient water in the water collection ditch 1, the rain collection irrigation mechanism 3 can be in the natural irrigation mode, and the primary irrigation component 32 is started. When the rain collection irrigation mechanism 3 is in the strong irrigation mode, the secondary irrigation component 33 is started. The inner wall of the ditch 1 is also paved with an anti-seepage cloth 4, and a concealed pipe 5 is buried under the bottom wall of the ditch 1. The anti-seepage cloth 4 is located above the concealed pipe 5. The anti-seepage cloth 4 is used to prevent water in the ditch 1 from penetrating into the concealed pipe 5 or soil below, ensuring that the normal salt discharge function of the concealed pipe 5 is not affected by the water in the ditch 1.

[0030] When rainy days come, the rainwater collection irrigation mechanism 3 switches to the rainwater collection mode, and the rainwater collection component 31 is started. Rainwater is collected through the bracket 2 and the rainwater collection component 31 on the top of the ditch, and temporarily stored in the water collection ditch 1. When the rainwater storage in the water collection ditch 1 is sufficient, the rainwater collection irrigation mechanism 3 can be in the natural irrigation mode, and the first-level irrigation component 32 is started to irrigate or rinse the saline-alkali land to remove the salt in the soil. When the rainwater storage in the water collection ditch 1 drops to half or less, the rainwater collection irrigation mechanism 3 can be switched to the strong irrigation mode, and the second-level irrigation component 33 is started to continue to irrigate or rinse the saline-alkali land with the remaining water in the water collection ditch 1. Among them, through the rainwater collection mode of the rainwater collection irrigation mechanism 3, rainwater resources are effectively collected and utilized, the problem of shortage of fresh water resources in saline-alkali areas is solved, and the necessary fresh water resources are provided for saline-alkali land. At the same time, the salt discharge effect of the concealed pipe 5 can radiate to a certain area of ​​the saline-alkali land. After the drainage ditch 1 is excavated, the concealed pipe 5 can be pre-buried under the drainage ditch 1, so as to facilitate the laying of the concealed pipe 5, reduce the secondary excavation when the concealed pipe 5 is buried in the saline-alkali land, and support the implementation of water-based salt control technology. In addition, the natural irrigation mode, strong irrigation mode and salt discharge technology of the rainwater collection and irrigation mechanism 3 and the concealed pipe 5 can effectively remove the salt in the saline-alkali land, prevent the soil from returning to salt, and improve the soil structure and quality. At the same time, the bracket 2 adopts a modular detachable connection setting, so that the local rainwater collection and irrigation mechanism 3 can be quickly modularly repaired or replaced after damage, reducing maintenance costs and time.

[0031] Reference Figure 3 and Figure 4The rain collecting assembly 31 includes a plurality of fixed cover plates 311 disposed on the top of the water collecting ditch 1. The fixed cover plates 311 are fixedly connected to the top of the bracket 2, and the plurality of fixed cover plates 311 are spaced apart along the length direction of the water collecting ditch 1. A plurality of movable plate groups are also spaced apart along the length direction of the water collecting ditch 1. The plurality of movable plate groups are staggered with the plurality of fixed cover plates 311, and each movable plate group includes two rain collecting plates 312 symmetrically hinged on the bracket 2. An opening and closing component 313 is disposed between the two rain collecting plates 312 in the same movable plate group, and the opening and closing component 313 is used to drive the two rain collecting plates 312 to open or close synchronously.

[0032] The sides of the two rain collecting plates 312 in the same movable plate group that are close to each other are arranged in an inclined plane, and the two inclined planes can fit each other; when the rain collecting plate 312 needs to be closed, as the rain collecting plate 312 moves, the two inclined planes gradually approach and finally fit together to form a flat and tight sealing surface, thereby reducing the evaporation of water on non-rainy days, and preventing rainwater or foreign objects from entering the interior of the water collecting ditch 1, thereby improving the dustproof ability of the system. A plurality of support rods 314 are fixedly provided on the side of the bracket 2 away from the water collecting ditch 1, and an auxiliary support plate 315 is fixedly provided on the top of the support rod 314. After the rain collecting plate 312 is opened, one side of the rain collecting plate 312 fits with the auxiliary support plate 315, providing additional auxiliary support for the rain collecting plate 312, improving the stability of the rain collecting plate 312 in the open state, and reducing the displacement or shaking caused by wind or gravity. A plurality of hinges 316 are also provided between the rain collecting plate 312 and the bracket 2. The plurality of hinges 316 are arranged along the length direction of the rain collecting plate 312. The hinges 316 are used to ensure that the rain collecting plate 312 operates smoothly during the opening and closing process, and at the same time strengthen the structural strength of the connection between the rain collecting plate 312 and the bracket 2, so that the rain collecting plate 312 is not easily broken due to external forces such as wind.

[0033] When rain comes, the rainwater collection irrigation mechanism 3 needs to switch to the rainwater collection mode. First, the opening and closing components 313 are used to drive the two rainwater collection plates 312 to open synchronously. After the rainwater collection plates 312 are opened, a rainwater collection area is formed. The rainwater flows into the water collection ditch 1 under the guidance of the opened rainwater collection plates 312. When the rain stops, the rainwater collection plates 312 are closed by the opening and closing components 313, so that the top of the water collection ditch 1 is in a closed state to prevent water evaporation or impurities from entering during non-rainy days. The fixed cover plate 311 and the movable plate group are spaced along the length direction of the water collection ditch 1 to form an alternating opening and closing structure. With the opening and closing setting of the rainwater collection plates 312, not only the efficient collection of rainwater is achieved, and the full utilization of rainwater resources is ensured, but also the stability of the entire rainwater collection assembly 31 is ensured, and the evaporation of water or the entry of impurities and pollutants in the water collection ditch 1 during non-rainy days is reduced, so as to maintain the cleanliness and water quality of the water collection ditch 1.

[0034] Reference Figure 4 and Figure 5The opening and closing component 313 includes two rotating shafts 3131 corresponding to the two rain collecting plates 312, the rotating shafts 3131 are fixedly connected to the corresponding rain collecting plates 312, and the rotating shafts 3131 are rotatably connected to the bracket 2. The driving shaft 3132 is rotatably connected to the bracket 2, and the driving shaft 3132 is located between the two rotating shafts 3131. A driving gear 3133 is fixedly sleeved on the driving shaft 3132, and a driven gear 3134 is fixedly sleeved on the rotating shaft 3131; two racks 3135 corresponding to the two driven gears 3134 are slidably connected to the bracket 2 in the horizontal direction, and the two racks 3135 are meshed with the driving gear 3133, and the two racks 3135 move in opposite directions and mesh with the corresponding driven gears 3134. A worm gear 3136 is fixedly sleeved on the driving shaft 3132, and a worm 3137 is rotatably connected to the bracket 2, and the worm 3137 and the worm gear 3136 are meshed with each other. A driving motor 3138 is also provided at one end of the worm 3137 .

[0035] When it is necessary to open the rain collecting plate 312, first start the driving motor 3138, the driving motor 3138 drives the worm 3137 to rotate, the worm 3137 drives the driving shaft 3132 to start rotating by meshing with the worm wheel 3136, the rotation of the driving shaft 3132 drives the driving gear 3133 to rotate, the driving gear 3133 meshes with the two racks 3135, so that the two racks 3135 move in opposite directions. Then the rack 3135 drives the two rotating shafts 3131 to rotate synchronously by meshing with the driven gear 3134, and the rotation of the rotating shaft 3131 drives the rain collecting plate 312 to open, forming a rainwater collection area. When it is necessary to close the rain collecting plate 312, the driving motor 3138 is started in reverse, and through the above reverse process, the two rain collecting plates 312 are closed synchronously, and the closed state of the top of the water collecting ditch 1 can be restored. The cooperation of the worm gear 3136, worm 3137, gears, rack 3135, etc. realizes precise control and synchronous opening and closing of the rain collecting plate 312, ensuring the convenience and efficiency of rainwater collection. In addition, due to the self-locking characteristics of the worm gear 3136, worm 3137, the energy consumption of the rain collecting plate 312 in the open and closed states is reduced, and the operating cost of the rain collecting component 31 is reduced. At the same time, the stability of the rain collecting plate 312 in the closed state is ensured, so that the rain collecting plate 312 is not easily affected by wind force and other factors and is abnormally opened.

[0036] Reference Figure 5 and Figure 6The rain collecting assembly 31 also includes a solar panel 317 disposed on the fixed cover 311, a battery 318 connected to the solar panel 317, a raindrop sensor and a controller. The driving motor 3138 is connected to the battery 318, and the raindrop sensor is connected to the bracket 2 for detecting raindrops and sending a detection signal. The controller is connected to the raindrop sensor and the driving motor 3138 for receiving the detection signal to know whether it is raining. When it is raining, the controller sends a control signal to the driving motor 3138 so that the driving motor 3138 drives the rain collecting plate 312 to expand outside the water collecting ditch 1 to collect rainwater.

[0037] When the raindrop sensor detects raindrops, it will send out a detection signal. After receiving the detection signal, the controller determines whether it is in a raining state. The controller sends a control signal to the drive motor 3138 according to the preset program. When the drive motor 3138 receives the control signal, it starts and drives the opening and closing component 313 to operate, so that the rain collecting plate 312 is unfolded to the outside of the water collecting ditch 1 and starts to collect rainwater. When the rain stops, the controller determines that the rain has ended. The controller sends a closing signal to the drive motor 3138, and the drive motor 3138 starts in reverse, so that the rain collecting plate 312 is closed and the closed state of the top of the water collecting ditch 1 is restored. Among them, the rain collecting component 31 can be automatically started according to the rainfall situation, realizing the intelligent and automatic control of the rain collecting component 31, reducing human intervention, and ensuring the timeliness and efficiency of rainwater collection, thereby improving the utilization rate of rainwater resources. The solar panel 317 generates electrical energy under lighting conditions and transmits it to the battery 318 through the internal circuit. The battery 318 stores electrical energy. When the opening and closing component 313 needs to be started, the battery 318 provides power to the drive motor 3138 so that the drive motor 3138 controls the operation of the opening and closing component 313. The solar energy is used as the energy source of the drive motor 3138, which reduces the dependence on traditional electricity, so that the opening and closing component 313 can achieve energy self-sufficiency, improve the independence and reliability of the operation of the rainwater collection and irrigation mechanism 3, and reduce the operating cost.

The primary irrigation assembly 32 includes a gate chamber 321 fixed on the side wall of the water collection ditch 1, and an electric gate 322 is arranged on the gate chamber 321, and the electric gate 322 is connected to the battery 318. The number of primary irrigation assemblies 32 can be flexibly increased based on actual needs.

[0039] When there is sufficient water in the water collection ditch 1, the electric gate 322 can be opened from bottom to top, and the water in the water collection ditch 1 will automatically flow from the opening of the gate chamber 321 to the saline-alkali land for irrigation or washing. When the electric gate 322 receives the closing command, the electric gate 322 closes the opening of the gate downward to prevent the water from continuing to flow through. The electric gate 322 is also powered by solar panels and batteries 318, which reduces dependence on traditional electricity and reduces energy consumption.

[0040] Reference Figure 6 The secondary irrigation assembly 33 includes an irrigation pipe 331 disposed in the water collection ditch 1, one end of the irrigation pipe 331 is located outside the water collection ditch 1, and the other end is located at the bottom wall of the water collection ditch 1. A water pump 332 is disposed on the irrigation pipe 331, and the water pump 332 is connected to the battery 318. The number of secondary irrigation assemblies 33 can be flexibly increased based on actual needs.

[0041] When the water level in the water collection ditch 1 drops to half or lower, and the primary irrigation assembly 32 can no longer drain water, the pump 332 can be started to extract water from one end of the irrigation pipe 331 on the bottom wall of the water collection ditch 1 to continue irrigating or washing the saline-alkali land. The pump 332 can also be powered by the battery 318, reducing dependence on traditional electricity and reducing energy consumption.

[0042] The implementation principle of a dual-purpose ditch for water collection, irrigation and drainage in saline-alkali land in the embodiment of the present application is as follows: when rainy days come, the rain collection irrigation mechanism 3 automatically switches to the rain collection mode, the rain collection component 31 is started, and rainwater is collected through the bracket 2 and the rain collection component 31 at the top of the ditch, and temporarily stored in the water collection ditch 1. When the rainwater storage in the water collection ditch 1 is sufficient, the rain collection irrigation mechanism 3 can be in the natural irrigation mode, and the first-level irrigation component 32 is started to irrigate or rinse the saline-alkali land to remove the salt in the soil. When the rainwater storage in the water collection ditch 1 drops to half or less, the rain collection irrigation mechanism 3 can be switched to the strong irrigation mode, and the second-level irrigation component 33 is started to use the remaining water in the water collection ditch 1 to continue to irrigate or rinse the saline-alkali land. The rainwater collection mode of the rainwater collection irrigation mechanism 3 is used to effectively collect and utilize rainwater resources, solve the problem of freshwater shortage in saline-alkali areas, provide necessary freshwater resources for saline-alkali land, support the implementation of water-based salt control technology, and cooperate with the natural irrigation mode, strong irrigation mode and concealed pipe 5 salt discharge technology of the rainwater collection irrigation mechanism 3 to effectively remove salt from the saline-alkali land, prevent soil salt return, and improve soil structure and quality. At the same time, the bracket 2 adopts a modular detachable connection setting, so that the local rainwater collection irrigation mechanism 3 can be quickly modularly repaired or replaced after damage, reducing maintenance costs and time.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
