Description

Technical Field

[0001] This utility model relates to the field of soil improvement technology, and more specifically, to a drainage structure for improving saline-alkali land soil. Background Technology

[0002] In the process of improving saline-alkali soil, drainage is one of the key projects. Its essence is to actively remove excess saline water from the soil, break the imbalance cycle of "salt input > salt output", regulate the groundwater level, improve the soil water and air environment, and create the preconditions for subsequent chemical and biological improvement.

[0003] For example, an existing patent (publication number: CN223110480U) discloses a soil improvement and drainage device for saline-alkali land. This device uses a stirring motor to drive a stirring shaft and stirring rod to thoroughly mix the soil conditioner and water, ensuring the conditioner is evenly mixed in the water to form an effective improvement solution. A water pump then precisely delivers the solution to a spray head for even spraying, ensuring the solution evenly covers the surface of the saline-alkali land. This increases the contact area between the conditioner and the soil, thereby accelerating the soil improvement process and improving the improvement effect, efficiency, and accuracy of the improvement work. The design of the water collection trough effectively collects excess water from the saline-alkali land and automatically drains it through a drainage pipe and pump. This automatic drainage system maintains unobstructed drainage in the saline-alkali land, preventing water accumulation that could exacerbate salinization, while also reducing the labor intensity of manual drainage.

[0004] Currently, due to the continued interference of the natural environment and human activities, salt will continue to accumulate again, requiring long-term maintenance and treatment. However, the above-mentioned devices still require a large amount of water resources in each soil improvement process, and cannot be collected and reused, making them unsuitable for areas where saline-alkali land is caused by drought. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a drainage structure for improving saline-alkali land, which solves the problem that the existing soil improvement drainage structure still requires a large amount of water resources in each soil improvement process, and cannot be collected and reused, making it difficult to be applied to areas where saline-alkali land is caused by drought factors.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drainage structure for improving saline-alkali soil, including a drainage pipe with perforated surface, a filter material on the surface of the drainage pipe, and a treatment box. A water collection tank is fixedly installed on one side of the treatment box. The bottom of the water collection tank is connected to the output end of the drainage pipe. A first water pump is installed on the top of the water collection tank. The input and output ends of the first water pump are respectively connected to a first conveying pipe and a second water supply pipe. The first conveying pipe extends to the bottom of the inner cavity of the water collection tank. The output end of the second water supply pipe is connected to the inner cavity of the treatment box. A drainage component is installed at the bottom of the treatment box. A liquid level sensor is also installed in the inner cavity of the treatment box. A control cabinet and a stirring and feeding component are also installed on the treatment box. A second water pump is fixedly connected to the bottom of the inner cavity of the treatment box. A first valve is installed on the output pipe of the second water pump.

[0007] Preferably, the drainage pipe is inclined downwards towards the water collection tank.

[0008] Preferably, the drainage assembly includes a drainage channel at the bottom of the treatment box, the output end of the drainage channel is connected to a drainage pipe, and a cylinder is also provided inside the treatment box. The output end of the cylinder is connected to a switch, which can slide vertically inside the treatment box.

[0009] Preferably, a photovoltaic module is installed on the top of the processing box, and a switch plate is also hinged to the top of the processing box.

[0010] Preferably, the mixing and feeding assembly includes a mixing shaft, which is rotatably installed inside the processing box. Multiple mixing and feeding pipes are fixed in the circumferential direction inside the mixing shaft. A gear one is fixed to the top of the mixing shaft. A motor is installed on the top of the processing box. A gear two is fixed to the output end of the motor. The gear one and gear two mesh with each other. A feeding bucket is also fixed to the top of the processing box. The bottom end of the feeding bucket is rotatably connected to the mixing shaft. At the same time, the bottom end of the feeding bucket is also connected to the mixing and feeding pipes.

[0011] Preferably, the discharge ports of the plurality of mixing and feeding pipes are arranged in a spiral descending manner at equal intervals.

[0012] Preferably, the top of the feeding hopper is threaded with a hopper lid, the bottom of the feeding hopper is provided with a second valve, a second cylinder is installed on the hopper lid, and a pressure plate is connected to the telescopic end of the second cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention uses rainwater or irrigation water to remove salt from saline-alkali land and guide it through a drainage pipe to a water collection tank. A liquid level sensor detects the liquid level in the tank, and when the liquid level does not reach a preset standard, the drainage system shuts off. A first water pump then pumps water from the water collection tank into the treatment tank via a first delivery pipe and a second water supply pipe. A mixing and feeding component adds and stirs the improved solution. When the saline-alkali land needs improvement again, the improved water can be re-irrigated through a second water pump, a first valve, and an external water pipe, achieving the effect of soil improvement while making full use of water resources and reducing waste.

[0014] This invention uses a stirring shaft to add a modifier into the feeding bucket. The modifier is then evenly added to the brine along the stirring feeding pipe. The motor drives gear two to mesh with gear one, which in turn drives the stirring shaft to rotate, thus stirring the feeding pipe and facilitating thorough mixing of the modifier and the brine.

[0017] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0018] As attached Figure 1 To be continued Figure 5This utility model provides a drainage structure for improving saline-alkali soil, including a drainage pipe 1 with perforated surface, a filter material 2 on the surface of the drainage pipe 1, the drainage pipe 1 being buried in saline-alkali soil, allowing brine to seep into the drainage pipe 1 through the perforations, and the filter material 2 being permeable to water and soil to prevent pipe blockage. It also includes a treatment tank 3, with a water collection tank 4 fixedly installed on one side of the treatment tank 3. The bottom of the water collection tank 4 is connected to the output end of the drainage pipe 1. A first water pump 5 is installed on the top of the water collection tank 4, with its input and output ends connected to a first delivery pipe 6 and a second water supply pipe 7, respectively. The first delivery pipe 6 extends to the bottom of the inner cavity of the water collection tank 4, and the output end of the second water supply pipe 7 is connected to the inner cavity of the treatment tank 3. A drainage component 8 is installed at the bottom of the treatment tank 3, and a liquid level sensor 9 is also installed in the inner cavity of the treatment tank 3. A control cabinet 10 and a mixing and feeding component 11 are also installed on the treatment tank 3. A second water pump 12 is fixedly connected to the bottom of the inner cavity of the treatment tank 3, and a first valve 13 is installed on the output pipe of the second water pump 12.

[0019] Specifically, rainwater or irrigation water carries away the salt in the saline-alkali land and flows it through the drainage pipe 1 to the water collection tank 4. The liquid level sensor 9 senses the liquid level in the treatment tank 3. When the liquid level in the treatment tank 3 does not reach the preset standard, the drainage component 8 is turned off. The first water pump 5 can pump water from the water collection tank 4 into the treatment tank 3 through the first delivery pipe 6 and the second water supply pipe 7. The mixing and feeding component 11 adds and stirs the improvement solution. When the saline-alkali land needs to be improved again, the improved water can be re-irrigated into the saline-alkali land through the second water pump 12, the first valve 13 and the external water pipe to achieve the effect of soil improvement. It can also make full use of water resources and reduce waste. When the liquid level sensor 9 senses that the liquid level in the treatment tank 3 has reached the preset standard, the first water pump 5 stops working and the drainage component 8 is opened to drain the excess water.

[0020] Preferably, the drainage pipe 1 is inclined downwards towards the water collection tank 4 to facilitate the flow of brine that seeps into the drainage pipe 1 into the water collection tank 4.

[0021] Preferably, the drainage assembly 8 includes a drainage channel 81 located at the bottom of the treatment tank 3. The output end of the drainage channel 81 is connected to a drainage pipe 82. The treatment tank 3 is also equipped with a cylinder 83. The output end of the cylinder 83 is connected to a switch 84. The switch 84 can slide vertically inside the treatment tank 3. The cylinder 83 is extended or retracted according to the signal sensed by the liquid level sensor 9, thereby blocking or opening the drainage channel 81.

[0022] Preferably, a photovoltaic module 14 is installed on the top of the processing box 3, and a switch plate 15 is also hinged to the top of the processing box 3.

[0023] The switch plate 15 facilitates sampling by staff, allowing for the preparation of appropriate improvers based on the salt content in the water within the treatment tank 3.

[0024] Preferably, the mixing and feeding assembly 11 includes a mixing shaft 111, which is rotatably installed inside the processing box 3. Multiple mixing and feeding pipes 112 are fixed in the circumferential direction inside the mixing shaft 111. A gear 113 is fixed to the top of the mixing shaft 111. A motor 114 is installed on the top of the processing box 3. A gear 115 is fixed to the output end of the motor 114. The gear 113 and the gear 115 mesh with each other. A feeding bucket 116 is also fixed to the top of the processing box 3. The bottom end of the feeding bucket 116 is rotatably connected to the mixing shaft 111. At the same time, the bottom end of the feeding bucket 116 is also connected to the mixing and feeding pipes 112.

[0025] Specifically, an improver is added to the feeding tank 116. The improver is then evenly added to the brine along the mixing feeding pipe 112. The motor 114 drives the gear 115 to mesh with the gear 113, which in turn drives the mixing shaft 111 to rotate, causing the mixing feeding pipe 112 to mix, thus facilitating the thorough mixing of the improver and the brine.

[0026] Preferably, the discharge ports of the multiple mixing and feeding pipes 112 are arranged in a spiral downward arrangement at equal intervals, so that the modifier can be added to the brine from different heights, which facilitates rapid mixing.

[0027] Preferably, a lid 117 is threaded onto the top of the feeding hopper 116, a second valve 118 is provided at the bottom of the feeding hopper 116, a cylinder 119 is installed on the lid 117, and a pressure plate 120 is connected to the telescopic end of the cylinder 119.

[0028] Specifically, when the second valve 118 is opened, the cylinder 119 extends and retracts, which can drive the pressure plate 120 to press down the modifier, so that the modifier can be evenly delivered to multiple mixing and feeding pipes 112.

[0029] In this application, the control cabinet 10 is used to control the aforementioned related electrical equipment, while the photovoltaic module 14 can supply power to all electrical equipment.
