[0039] Embodiment 1

[0040] See also Figure 1-3 The utility model provides a technical solution: a device for repairing saline-alkali land by using water conservancy, comprising a seepage pipe 1, a plurality of seepage holes 11 are opened on the seepage pipe 1, a mounting frame 2 is coaxially rotated in the seepage pipe 1, a scraper 3 extending along the axial direction of the seepage pipe 1 is fixedly connected to the mounting frame 2, and one side of the scraper 3 is in contact with the inner circular surface of the seepage pipe 1;

[0041] The mounting frame 2 is connected to a driving unit, and the driving unit is used to drive the mounting frame 2 to rotate around the axis of the seepage pipe 1.

[0042] The seepage pipe 1 is formed by splicing two semicircular pipes, and the side planes of the two semicircular pipes along the circumferential direction are fixedly connected with convex strips 13, and the convex strips 13 are provided with through holes. The threaded ends of the bolts are sequentially passed through the through holes on the two convex strips 13 and screwed into the nuts to fix the two semicircular pipes into a closed-loop tubular structure for water seepage and salt removal. The seepage pipe 1 is divided into two semicircular pipes and spliced ​​and installed through a detachable connection method, so as to facilitate the installation or maintenance of the internal structure of the seepage pipe 1.

[0043] When in use, the seepage pipe 1 is buried below the ground of the saline-alkali land. The salt water in the soil flows into the seepage pipe 1 from the seepage holes 11 during the sedimentation process. As the soil ambient temperature and other factors change, part of the salt in the salt water is precipitated and crystallized, and then the salt crystals adhere to the seepage pipe 1. During long-term use, a large amount of salt crystals accumulate, causing blockage of the seepage pipe 1. The driving part drives the mounting frame 2 and the scraper bar 3 to rotate in the seepage pipe 1, so that the scraper bar 3 and the inner circular surface of the seepage pipe 1 move relative to each other, and the inner circular surface of the seepage pipe 1 is scraped and cleaned to push and separate the salt crystals adhered to the inner circular surface of the seepage pipe 1. Finally, the salt crystals are discharged together with the salt water in the seepage pipe 1, so that the seepage pipe 1 remains unobstructed, thereby improving the drainage efficiency of the seepage pipe 1.

[0044] In this embodiment: the mounting frame 2 includes a rotating shaft 21 coaxial with the seepage pipe 1 and two supporting rings 22 respectively fixedly connected to both ends of the rotating shaft 21 ; and both ends of the scraper strip 3 are respectively fixedly connected to the two supporting rings 22 .

[0045] Two annular grooves 12 are formed on the inner circular surfaces at both ends of the seepage pipe 1 , and the two support rings 22 are rotatably matched with the two annular grooves 12 respectively.

[0046] The inner circumferential surfaces of the two support rings 22 are coplanar with the inner circumferential surface of the seepage pipe 1 .

[0047] The support ring 22 supports the seepage pipe 1 to improve the pressure resistance of the seepage pipe 1 and make the structure of the device more stable. The support ring 22 is embedded in the annular slide groove 12 to limit the free sliding of the mounting frame 2 on the seepage pipe 1 along the axial direction of the seepage pipe 1, and the inner circular surface of the support ring 22 is coplanar with the inner circular surface of the seepage pipe 1 to reduce the shielding area of ​​the support ring 22 on the seepage pipe 1, improve the permeability of the inside of the seepage pipe 1, and promote the discharge of salt water and salt crystals. At the same time, the scraper 3 is supported by two support rings 22, so that the side of the scraper 3 facing away from the rotating shaft 21 is stably fitted with the inner circular surface of the seepage pipe 1, and then when the rotating shaft 21 drives the two support rings 22 to rotate synchronously in the same direction, the scraper 3 stably scrapes the inner circular surface of the seepage pipe 1, and then scrapes and cleans the salt crystals attached to the seepage pipe 1.

[0048] In this embodiment: the scraper strip 3 is spiral-shaped.

[0049] By setting the scraper bar 3 into a spiral shape, when the scraper bar 3 follows the support ring 22 to rotate in the seepage pipe 1, the scraper bar 3 will scrape and separate the salt crystals attached to the inner circular surface of the seepage pipe 1, and at the same time, the scraper bar 3 pushes the salt crystals to rotate and lift. Under the action of gravity, the salt crystals slide downward along the side of the scraper bar 3 facing the rotation direction, and then are pushed by the scraper bar 3 to move axially along the seepage pipe 1, and the direction of the axial movement of the salt crystals along the seepage pipe 1 is the discharge direction of the brine, thereby promoting the discharge of brine and salt crystals in the seepage pipe 1.

[0050] In this embodiment: the plurality of seepage holes 11 are divided into a plurality of groups along the axial direction of the seepage pipe 1, and each group of the seepage holes 11 is evenly distributed along the circumference of the seepage pipe 1;

[0051] The scraper strip 3 is provided with a plurality of receiving grooves 31 corresponding to the plurality of groups of water seepage holes 11 on one side of the inner circular surface of the water seepage pipe 1, and a ejector pin 32 is provided in the receiving groove 31 to slide along the radial direction of the water seepage pipe 1;

[0052] An elastic support member is disposed between one end of the receiving groove 31 facing away from the opening and one end of the ejector pin 32 facing the scraper strip 3 . When the elastic support member is in a naturally stretched state, the ejector pin 32 protrudes out of the receiving groove 31 .

[0053] In this embodiment, the end of the ejector pin 32 facing away from the rotating shaft 21 is in a ball head shape.

[0054] The elastic support member is a spring 33, which is embedded in the receiving groove 31, and one end of the spring 33 is fixedly connected to the ejector pin 32, and the other end of the spring 33 is fixedly connected to the plane of the receiving groove 31 facing away from the opening, so that the spring 33 plays a flexible supporting role for the ejector pin 32.

[0055] During use, when the ejector pin 32 is inserted into the first seepage hole 11 of the corresponding group of seepage holes 11, the driving unit drives the rotating shaft 21 to rotate forward, and the rotating shaft 21 drives the supporting ring 22 and the scraper strip 3 to rotate forward in the seepage pipe 1, and then the scraper strip 3 drives the ejector pin 32 to rotate forward, so that the ball head curved surface of the ejector pin 32 abuts against the side wall of the first seepage hole 11, and then the ejector pin 32 is pushed and slides into the storage groove 31, the spring 33 contracts to store energy, and the scraper strip 3 drives the ejector pin 32 to continue to rotate forward. When the ejector pin 32 slides to overlap with the second seepage hole 11, the spring 33 stretches freely to release energy, pushing the ejector pin 32 to slide out of the receiving groove 31, and the ball head curved surface of the ejector pin 32 abuts against the edge of the end of the seepage hole 11 facing the rotating shaft 21, and then the ejector pin 32 slowly slides into the second seepage hole 11 during the rotation process, scraping and separating the salt crystals attached to the side of the second seepage hole 11, so as to clean the second seepage hole 11 and improve the passability of the second seepage hole 11. Similarly, after the scraper bar 3 rotates one circle in the seepage pipe 1, all the seepage holes 11 in the group of seepage holes 11 are cleaned, thereby improving the permeability of the seepage pipe 1, promoting the discharge of salt in the soil, and improving the efficiency of saline-alkali land improvement and restoration work.

[0056] In this embodiment: the driving part includes two meshing bevel gears 41, a driving rod 42 and a rotating handle 43, wherein one of the bevel gears 41 is coaxial with the rotating shaft 21 and is fixedly connected;

[0057] One end of the driving rod 42 is fixedly connected to another bevel gear 41, and the other end of the driving rod 42 penetrates the wall of the seepage pipe 1 and extends out of the seepage pipe 1, and is fixedly connected to the rotating handle 43;

[0058] The middle portion of the driving rod 42 is rotatably matched with the pipe wall of the water seepage pipe 1 .

[0059] During use, the seepage pipe 1 is buried below the ground, and one end of the driving rod 42 outside the seepage pipe 1 is extended above the ground. When it is necessary to clean the salt crystals attached to the seepage pipe 1, the relevant technician manually rotates the handle 43 forward to make the driving shaft rotate forward, and the two meshing bevel gears 41 drive the rotating shaft 21 to rotate forward, and then the two support rings 22 drive the scraper 3 to rotate forward together, scraping and cleaning the salt crystals attached to the inner circular surface of the seepage pipe 1, and at the same time pushing the brine and salt crystals in the seepage pipe 1 to move axially along the seepage pipe 1 until the salt crystals are discharged from the seepage pipe 1. During the forward rotation of the scraper 3, the ejector pin 32 automatically cleans the corresponding seepage hole 11 to improve the permeability of the seepage pipe 1.

[0060] In this embodiment, the end of the driving rod 42 facing away from the rotating shaft 21 is also fixedly connected to a wind wheel 44 .

[0061] By setting the wind wheel 44, when there is natural wind, the wind wheel 44 is blown to rotate forward, and the wind wheel 44 provides power for the rotation of the driving rod 42, and then the driving rod 42 drives the rotating shaft 21 to rotate forward, so that the scraping strip 3 automatically performs the scraping and cleaning work, reducing the work intensity of related technical personnel.

[0062] Embodiment 2

[0063] See also Figure 4 , Figure 5 , which is different from the first embodiment in that the end of the ejector pin 32 facing away from the rotating shaft 21 is wedge-shaped, and the inclination direction of the wedge is the side facing the rotating direction of the rotating shaft 21 .

[0064] The edge of the water seepage hole 11 at one end in the water seepage pipe 1 which faces away from the rotation direction of the rotating shaft 21 is chamfered to facilitate the ejector pin 32 to slide out of the water seepage hole 11 smoothly.

[0065] During use, when the scraper bar 3 rotates forward in the seepage pipe 1, the ejector pin 32 is pushed close to the corresponding seepage hole 11, and the ejector pin 32 is embedded in the receiving groove 31 under the extrusion effect of the inner circular surface of the seepage pipe 1. When the ejector pin 32 coincides with the seepage hole 11, the extrusion force of the inner circular surface of the seepage pipe 1 on the ejector pin 32 disappears instantly, and then the spring 33 releases energy to push the ejector pin 32 to quickly insert into the seepage hole 11, and then impact the salt crystals attached to the seepage hole 11, promote the separation of the salt crystals from the side wall of the seepage hole 11, so as to clean the seepage hole 11; the scraper bar 3 continues to rotate forward, and the wedge-shaped inclined surface in the ejector pin 32 is against the chamfered inclined surface in the seepage hole 11, so that the ejector pin 32 is pushed to slide into the receiving groove 31, and then the cleaning work of the seepage hole 11 is completed.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
