Technical Field

The utility model belongs to the technical field of drainage and salt control, and in particular relates to a saline-alkali land drainage and salt control structure.

Background Art

The main characteristics of saline-alkali land are heavy and compacted soil, poor permeability, high salt content, mainly sodium chloride.

Large evaporation, high groundwater mineralization and high groundwater level caused by rain or groundwater are the root causes of saline-alkali land, which ultimately lead to high soil salinity, poor soil structure and fertility. Existing methods of controlling desalination are mainly based on irrigation and soil turning, but it is difficult to achieve the goal by washing salt with fresh water. Soil turning is only a temporary block and cannot be controlled for a long time. At the same time, it cannot prevent a large amount of rainwater from falling into the ground, and cannot effectively prolong and utilize the desalination of saline-alkali land brought by rainy seasons with excessive rain.

To this end, we proposed a saline-alkali land drainage and salt control structure to solve the above problems.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

1-3, the utility model provides a saline-alkali land drainage and salt control structure, including: a rainwater filtering and collecting structure 5, the outer bottom of the rainwater filtering and collecting structure 5 is fixedly connected to a treatment tank 8 through a drainage pipe 6 (part of the pipelines in the figure are not drawn), the bottom of the rainwater filtering and collecting structure 5 is fixedly connected to a humidifying structure, the humidifying structure is fixedly connected to a water storage tank 1 through an outlet pipe 2 (part of the pipelines in the figure are not drawn), a first water pump 3 is provided on the outlet pipe 2, a return pipe 9 is provided between the treatment tank 8 and the water storage tank 1, and a return pump is provided on the return pipe 9;

The first water pump 3 and the return water pump are electrically connected to the external computer.

When in use, the rainwater filtering and collecting structure 5 is laid in the area where rainwater is to be collected. In the season with more rain, the rainwater filtering and collecting structure 5 in the device can filter and collect rainwater, and collect the rainwater to the treatment pool 8 for sedimentation, disinfection and other operations to obtain purer water resources. After the treatment, the rainwater is pumped into the water storage tank 1 through the return water pump on the return water pipe 9, and can be supplied to the outside for use, and can also be used for drip irrigation in the salt return season. When the salt return season comes, the first water pump 3 on the outlet pipe 2 directly supplies water to the humidification structure, and drip irrigation is performed for the land below the rainwater filtering and collecting structure 5, thereby reducing the salt return and reducing the salinization of the land.

By setting up the rainwater filtering and collecting structure 5, the device can collect rainwater very well and has a good filtering effect. It not only prevents rainwater from directly entering the land, but also can filter rainwater to obtain relatively clean rainwater, and reduce the occurrence of clogging of the device itself by dirt and mud in the rainwater, so as to reduce the frequency of manual cleaning blockage and reduce the labor rate.

By setting up the water storage tank 1 and the treatment tank 8, rainwater can be collected and stored for domestic water use and drip irrigation in the salt return season. By setting up the humidification structure, drip irrigation can be provided for the soil to reduce the degree of land salinization.

Utilizing these structures, a saline-alkali land drainage and salt control structure is realized that can collect rainwater, drain and humidify as needed, and is more durable and less prone to clogging.

According to a further optimized solution, the rainwater filtering and collecting structure 5 comprises an outer shell 501 , and the inner side of the outer shell 501 is provided with a first dirt-blocking layer, a second dirt-blocking layer, and a bottom plate 506 in sequence from top to bottom, and the drainage pipe 6 is fixedly connected to the second dirt-blocking layer and the bottom plate 506 .

According to a further optimized solution, the first dirt blocking layer includes a first dirt blocking plate 502 , which is fixedly connected to the inner wall of the housing 501 , and a plurality of water holes 503 are arranged in an array on the first dirt blocking plate 502 .

The water holes 503 provided on the first dirt blocking plate 502 can block large debris such as branches and leaves.

A further optimized solution is that the second dirt blocking layer includes a second dirt blocking plate 504, which is fixedly connected to the inner wall of the outer shell 501, and a plurality of dirt blocking hollow tubes 505 are vertically penetrated on the second dirt blocking plate 504, and the dirt blocking hollow tubes 505 are arranged in an array, and the dirt blocking hollow tubes 505 are arranged between the projections of adjacent water holes 503.

The dirt-blocking hollow tube 505 is disposed between the projections of adjacent water holes 503 , and can effectively block leaves and other debris from entering the water holes 503 , thereby preventing them from entering the dirt-blocking hollow tube 505 and forming a blockage.

To further optimize the solution, a frustum-shaped protrusion is provided on the top of the outer side of the dirt-blocking hollow tube 505 , and the frustum-shaped protrusion is provided above the second dirt-blocking plate 504 .

The frustum-shaped protrusions can further prevent small pieces of gravel and sludge from entering the dirt-blocking hollow pipe 505, thereby preventing the dirt-blocking hollow pipe 505 from being blocked by gravel and sludge.

To further optimize the solution, dirt collecting grooves 507 are arranged at equal intervals on the bottom plate 506 , and the dirt-blocking hollow tubes 505 correspond vertically to the dirt collecting grooves 507 .

The sewage collecting tank 507 can allow the sludge mixed in the water to settle slightly when the rainfall is small. The rainwater first accumulates in the sewage collecting tank 507 and then overflows the sewage collecting tank 507 before being discharged by the drain pipe 6. Such a structural design can effectively reduce the probability of blockage of the drain pipe 6.

To further optimize the solution, a water level gauge 508 is provided between the second dirt baffle plate 504 and the bottom plate 506, the water level gauge 508 is fixedly connected to the outer shell 501, a second water pump 7 is provided on the drain pipe 6, and the water level gauge 508 is electrically connected to the second water pump 7 and an external computer respectively.

The cooperation between the water level meter 508 and the second water pump 7 can drain the rainwater between the second dirt baffle plate 504 and the bottom plate 506 more quickly, and can allow the treatment pool 8 to be higher than the rainwater filtering and collecting structure 5 .

A further optimized solution is that the humidification structure includes a plurality of drip irrigation pipes 4 arranged at equal intervals, one end of each of the drip irrigation pipes 4 is fixedly connected to the same water outlet pipe 2, the axis of the drip irrigation pipe 4 is perpendicular to the axis of the water outlet pipe 2, and drip irrigation holes are opened at equal intervals on the bottom surface of the drip irrigation pipe 4.

By arranging the drip irrigation pipe 4, the saline-alkali land can be humidified in the salt return season to alleviate soil salinization.
