Description

Technical Field

[0001] This utility model relates to the field of saline-alkali land management technology, specifically a covering and immersion device for saline-alkali land management. Background Technology

[0002] Saline-alkali land is a significant obstacle to agricultural production and the ecological environment. The core of saline-alkali land management lies in reducing the salt concentration in the topsoil. Common methods include freshwater irrigation for salt leaching and the application of chemical amendments. Among these methods, leaching soluble salts from the soil with water and carrying them into deeper layers is an effective physicochemical approach.

[0003] An existing patent (authorization announcement number: CN218999119U) discloses a seepage irrigation device for improving saline-alkali land. The key technical points of the solution are: when the seepage irrigation device is in use, if the filter plate needs to be cleaned, the filter plate assembly is used to remove the filter plate, which makes it easier to clean the filter plate, reduces the workload of the staff, improves work efficiency, and facilitates the maintenance or replacement of the filter plate, thus meeting the needs of use and improving the flexibility of installation. At the same time, when the internal water volume of the seepage irrigation device is full, the rain sensor detects the internal water volume and converts it into a signal, which is transmitted to the controller. The controller sends a signal to close the tank cover, reducing the phenomenon of internal water overflow and water backflow. The tank cover can be opened by a control switch.

[0004] However, the above-mentioned technical solutions still have certain drawbacks. Flood irrigation or extensive discharge means that the water cannot be concentrated and evenly applied to the specific soil areas that need treatment. Most of the water will diffuse or evaporate in all directions and cannot effectively infiltrate into the plant root zone, resulting in a large water consumption but poor salt leaching effect. Furthermore, traditional soaking methods are difficult to create a closed or semi-closed moist environment on the soil surface, which is not conducive to maximizing the dissolution and removal of salts under hydrostatic pressure. Therefore, a covered soaking device for saline-alkali land treatment is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a covering and immersion device for saline-alkali land treatment, so as to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A covering and immersion device for saline-alkali land treatment includes a storage tank, an inlet pipe with a liquid inlet function at the top of the storage tank, a dosing pipe for adding chemicals to the liquid at the top of the storage tank, multiple sets of reinforcement components at the bottom skirt of the storage tank, and an immersion component at the center of the bottom of the storage tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves uniform planar distribution of liquid by setting up an immersion washing component, a distribution network consisting of a guide pipe and multiple liquid outlet pipes, combined with a large number of seepage holes at the bottom.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] In one embodiment, such as Figures 1-4 As shown, a covering and immersion device for saline-alkali land treatment includes a storage tank 1, an inlet pipe 3 with a liquid inlet function at the top of the storage tank 1, a dosing pipe 4 for adding chemicals to the liquid at the top of the storage tank 1, multiple sets of reinforcement components 2 at the bottom skirt of the storage tank 1, and an immersion component 6 at the center of the bottom of the storage tank 1. In this embodiment, fresh water is injected into the storage tank 1 through the top inlet pipe 3, and a specific saline-alkali soil conditioner, such as an acidic substance, is added to the storage tank 1 through the dosing pipe 4 to neutralize the alkalinity. The conditioner is added to the storage tank 1 in a specific ratio. Through natural diffusion or simple stirring, the conditioner dissolves evenly in the water, forming a conditioner solution. Multiple sets of reinforcing components 2 at the bottom edge of the storage tank 1 stably fix the device to the ground. At this time, the immersion component 6 located at the center of the bottom of the storage tank 1 naturally covers the target soil area. Under its own gravity, the conditioner solution in the storage tank 1 flows naturally through the bottom outlet to the immersion component 6, uniformly immersing the saline-alkali soil.

[0020] In one embodiment, such as Figure 3 As shown, the reinforcement component 2 includes a mounting plate 21 fixedly installed at the bottom of the storage tank 1. The bottom of the mounting plate 21 is provided with a foot plug that can be inserted into the ground. The large planar area of ​​the mounting plate 21 can initially disperse the concentrated force applied to the storage tank 1, preventing excessive pressure on the base of the foot plug. Simultaneously, it increases the contact area with the ground, providing an initial anti-overturning support surface. Meanwhile, the foot plug relies on the static friction with the surrounding soil and the shear resistance of the soil to provide support, preventing the device from sinking vertically and improving stable horizontal support to prevent the storage tank 1 from overturning.

[0021] In one embodiment, such as Figure 2 As shown, the inner wall of the storage tank 1 is provided with a filter plate 7, and the outer wall of the storage tank 1 is provided with a scale bar 5 for observing the liquid level. A transparent observation window is provided next to the scale bar 5, and a drain valve is provided at the bottom of the storage tank 1. After the liquid enters the storage tank 1 from the top dosing pipe 4 and the liquid inlet pipe 3, it needs to pass through the filter plate 7 to reach the outlet at the bottom. During this process, the filter holes on the filter plate 7 will intercept any solid impurities that may be present in the water, such as incompletely dissolved drug particles or other suspended matter. The transparent observation window allows users to directly see the liquid level in the tank, providing an accurate measurement benchmark for the observed liquid level. The filter plate 7 prevents impurities from entering and clogging the downstream immersion assembly 6, avoiding cumbersome maintenance work.

[0022] In one embodiment, such as Figure 4 As shown, the immersion assembly 6 includes an inlet 61 that penetrates the center of the bottom of the storage tank 1. The bottom of the inlet 61 is connected to a cover 62. A guide pipe 63 is fixedly installed inside the cover 62. Multiple outlet pipes 64 are connected to the guide pipe 63. Multiple seepage holes 65 are provided at the bottom of the cover 62. A vertically upward vent pipe is also connected to the guide pipe 63. The top of the vent pipe is higher than the highest liquid level in the storage tank 1. When the valve at the bottom of the storage tank 1 is opened, the improved liquid flows out from the center of the storage tank 1 through the inlet 61 under its own gravity. The liquid first enters the guide pipe 63, which serves as the main channel and runs through the entire interior of the cover 62. The multiple outlet pipes 64 connected to the guide pipe 63 divert the liquid in the main channel to various corners of the cover 62, forming an efficient irrigation network. When the liquid begins to flow into the originally air-filled interior of the cover 62, the compressed air needs to be discharged through an outlet. The vertically upward exhaust pipe provides this outlet. Air is compressed by the liquid and smoothly discharged through the exhaust pipe into the space above the liquid storage tank 1, thereby avoiding air blockage and ensuring that the liquid can quickly fill the entire guide pipe 63 mesh. The top of the exhaust pipe is designed to be higher than the highest liquid level of the liquid storage tank 1, ensuring that even when the liquid storage tank 1 is full, the liquid will not overflow from the exhaust pipe. As a supplement: when the liquid fills the pipe network, a shallow water layer will be formed inside the cover 62. Then, under the action of static pressure, it will seep evenly into the soil below through multiple seepage holes 65 at the bottom of the cover 62. The cover 62 seals the entire rinsing area, preventing liquid runoff and ineffective evaporation, and forcing almost all the water to seep vertically downward, thereby efficiently rinsing the salt in the soil to the deep layers.

[0023] In one embodiment, such as Figure 4As shown, the cover 62 is made of PVC coated fabric and is rectangular in shape, with weighted edges. PVC coated fabric is a typical composite material that forms a physical barrier through its impermeable coating. This barrier effectively prevents liquid from evaporating upwards into the air or flowing horizontally in all directions, forcing the liquid to have only one option: to seep downwards into the soil through the drainage holes 65 at the bottom. Simultaneously, the weighted edges provide sufficient wind resistance to prevent wind from penetrating from below the cover 62 and overturning it.

[0024] The above embodiment discloses a covering and leaching device for saline-alkali land treatment. The device is moved to the target area requiring treatment, and is securely fixed to the ground by the reinforcing components 2 at the bottom of the storage tank 1 to prevent tipping. The covering 62 of the leaching component 6 is unfolded, covering the target soil area flat. The weighted edges of the covering 62 ensure a tight seal against the ground. The required clean water is injected through the inlet pipe 3 at the top of the storage tank 1. The volume of water injected is precisely controlled by the scale strip 5 and transparent observation window on the outer wall of the storage tank 1. The liquid first enters the guide pipe 63 inside the covering 62, and then is evenly distributed to all corners of the covering 62 through multiple outlet pipes 64. The exhaust pipe smoothly vents the air accumulated inside the covering 62 back to the top of the storage tank 1, preventing air blockage and ensuring unparalleled liquid flow. After forming a uniform water layer inside the covering 62, the liquid seeps evenly into the soil under static pressure through the dense permeation holes 65 at the bottom.

[0025] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
