[0002] Saline-alkali land is widely distributed in northern my country, with a total area of 36.9 million hectares. Comprehensive improvement and utilization of saline-alkali land is an important channel and means to ensure my country's future food security and expand agricultural development space. It is estimated that the area of saline-alkali land with agricultural utilization value in the near future is about 3.25 million mu.
[0003] There are many types of saline-alkali land improvement technologies. At present, the most effective saline-alkali land improvement solution is to apply a large amount of organic matter and perform sufficient leaching. However, for different types of saline-alkali land environments, corresponding organic and inorganic materials need to be used to prepare the improvers. However, the irrigation and salt washing measures in saline-alkali land will generate saline wastewater, and the salt cannot be completely removed from the saline-alkali land. The salt enters the lower soil layer with a large amount of irrigation water, and gradually gathers on the soil surface again during the continuous evaporation of the soil, aggravating the degree of soil salinization.
[0004] Existing saline-alkali land improvement devices usually adopt centralized treatment measures, which are expensive, energy-intensive, and have high operating costs. Saline-alkali lands are generally located in remote areas, and basic support facilities such as power supply are incomplete, making it difficult for these saline-alkali land improvement devices to be truly put into practical use.

[0012] When the evaporation plate is rotated to a vertical direction, the entire device is in a retracted state, and when the evaporation plate is rotated to a horizontal direction, the entire device is in an unfolded state.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0023] The following description sets forth specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] like Figure 1 to Figure 2 As shown, the saline-alkali land improvement device using natural evaporation of the utility model includes a fixing mechanism and an evaporation mechanism, and the evaporation mechanism includes an evaporation plate 3 and an evaporation material 4, and the evaporation material 4 is arranged on the evaporation plate 3. The fixing mechanism and the evaporation plate 3 are rotatably connected by a connecting mechanism 2, and the device can be unfolded and folded through the connecting mechanism.
[0025] The fixing mechanism includes two fixing plates 1 arranged in a vertical direction, which are arranged in parallel with each other and have a certain gap between them. The bottom of the fixing plate 1 is inserted into a ditch, and there is wastewater left after precipitation or irrigation and salt washing in the ditch, and the water in the ditch has a high salt content. During use, the bottom of the fixing plate 1 is inserted into the soil below 20 cm to ensure the stability of the entire device. The top of the fixing plate 1 is rotatably connected to the evaporation plate 3 through the connecting mechanism 2.
[0026] The evaporation plate 3 is located above the fixed plate 1 and is made of light plastic. The evaporation material 4 is flatly fixed on the evaporation plate 3. The evaporation plate 3 is rotatably connected to the fixed plate 1. Under the action of manpower or an external electric mechanism, the evaporation plate 3 rotates around the top of the fixed plate 1 to realize the opening and closing of the device.
[0027] The connection mechanism 2 can be a hinge with a limiting function. The leaf piece on one side of the hinge is fixedly connected to the fixed plate 1, and the leaf piece on the other side of the hinge is fixedly connected to the evaporation plate 3. During the rotation of the hinge, the angle between the fixed plate 1 and the evaporation plate 3 changes, thereby realizing the deployment and folding of the device. With the rotation of the hinge, when the evaporation plate 3 rotates to the vertical direction, the entire device is in a folded state. Figure 3 When the evaporation plate 3 is rotated to the horizontal direction, the entire device is in an unfolded state, as shown in FIG. Figure 2 shown.
[0028] The evaporation material in this embodiment adopts a rope-shaped porous capillary evaporation material, the upper end of the evaporation material 4 is fixedly connected to the evaporation plate 3, the lower end of the evaporation material 4 is located in the gap between the two fixed plates 1, and the bottom end of the evaporation material 4 is located in the ditch. The evaporation material 4 can continuously absorb the high-salinity water in the ditch into the evaporation material under the action of evaporation and capillary force. Under the action of sunlight and air flow, the water in the evaporation material 4 is continuously evaporated, so that the salt contained in the water is continuously crystallized on the surface of the evaporation material.
[0029] The two evaporation plates 3 are both provided with evaporation materials. Since the evaporation materials in this embodiment are in rope form, a plurality of rope-shaped evaporation materials 4 are provided along the surface of the evaporation plates 3. The rope-shaped evaporation materials corresponding to the surfaces of the two evaporation plates are fixedly connected by a limiting sealing mechanism 5.
[0030] The limiting and sealing mechanism 5 in this embodiment is a U-shaped plate, and the side plates on both sides thereof are fixedly connected to the evaporation materials on the evaporation plates on both sides. The limiting and sealing mechanisms are arranged at intervals along the length direction of the evaporation materials. Through the limiting and sealing mechanism, on the one hand, the water in the ditch can be prevented from evaporating directly through the physical shielding and covering effect; on the other hand, the evaporation materials are limited during the rotation of the evaporation plates, so that the evaporation materials on the evaporation plates are arranged neatly.
[0031] During use of the device, the fixed plate is inserted downward into the soil at the bottom of the ditch where saline wastewater is stored, and the evaporation plate 3 is unfolded through the connecting mechanism 2. Figure 2 As shown, the evaporation plate 3 is laid flat on the surface of the saline-alkali land. The evaporation material 4 and the limit sealing mechanism 5 are installed. Under the action of sunlight, the evaporation material 4 absorbs water by capillary force and evaporates continuously. The salt in the groundwater crystallizes and accumulates on the evaporation material 4. It is manually collected and removed regularly, thereby enriching the soil salt and permanently removing it from the soil. When it rains, the evaporation plate 3 is folded up and fixed upright. At this time, precipitation is allowed to fall into the saline-alkali land originally covered by the evaporation plate. Through precipitation leaching, the saline wastewater is collected in the ditch, or water is irrigated to suppress salt.
[0032] The above is a detailed introduction to the saline-alkali land improvement device using natural evaporation provided by the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the utility model. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the utility model. The various modifications to these embodiments will be obvious to professionals and technicians in this field, and the general principles defined in this article can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown in this article, but will conform to the widest range consistent with the principles and novel features disclosed in this article.
