Description

Technical Field

[0001] This utility model relates to the field of well technology, specifically to a combined caisson for agricultural water supply. Background Technology

[0002] Agricultural irrigation plays a vital role in ensuring food production and sustainable agricultural development. With the growth of the global population and the impact of climate change, the rational allocation and efficient use of water resources have become particularly important, especially in arid and semi-arid regions where water supply often depends on the extraction and allocation of groundwater. Therefore, the construction of reliable and efficient agricultural water supply systems to ensure a stable water supply is crucial for agricultural production. Caissons, as a common underground water well structure, are mainly used to extract water from underground to the surface through the load-bearing capacity of the well walls.

[0003] Traditional agricultural water supply caissons typically use cast-in-place concrete structures. However, this method has several drawbacks, including long construction cycles, significant weather-related delays, high difficulty in quality control, and the inability to reuse caissons. While some existing precast caissons have addressed these issues to some extent, they still have shortcomings, particularly in the connection between caisson modules, sealing, and prevention of siltation at the bottom. Specifically, the connection methods between modules are complex, leading to low efficiency during on-site installation. Furthermore, the sealing performance is not ideal, easily causing leakage in the caisson wall, which in turn contaminates the well water, affecting water quality and usability.

[0004] To address these issues, improvements are needed in the design of caissons in terms of modular design, connection technology, and the selection of sealing materials. Simpler and more efficient modular connection methods and new sealing materials can be considered to improve sealing performance and prevent water pollution caused by leakage. Summary of the Invention

[0005] The purpose of this invention is to provide a modular caisson specifically for agricultural water supply, which has a more stable modular structure and the advantage of effectively preventing water seepage, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined caisson for agricultural water supply, comprising a well shaft, an installation groove at the top of the well shaft, a first fixing block at the top of the well shaft, a plurality of first sliding grooves on the surface of the first fixing block, a first spring fixedly connected to the inner cavity of each of the plurality of first sliding grooves, a limit block fixedly connected to the other end of the first spring, and the limit block slidably connected to the inner cavity of the first sliding groove, a second fixing block at the top of the first fixing block, a plurality of first locking blocks fixedly connected to the bottom of the second fixing block, one side of the first locking block locking into the inner cavity of the first sliding groove and contacting the limit block, a fixing sleeve fixedly connected to the top of the second fixing block, a plurality of second locking blocks arranged in a circular array fixedly connected to the inner cavity of the fixing sleeve, a plurality of second sliding grooves at the bottom of the well shaft, a locking mechanism provided in the inner cavity of each of the plurality of second sliding grooves, and one side of the locking mechanism contacting the second locking block.

[0007] Furthermore, as a preferred embodiment of the present invention, the locking mechanism includes a second spring fixedly connected to the inner cavity of the second slide groove, and a slide rod fixedly connected to the other end of the second spring, one end of the slide rod being locked with the second locking block.

[0008] Furthermore, as a preferred embodiment of this utility model, the surfaces of the first fixing block and the first sliding groove are provided with a plurality of spiral grooves, and the surfaces of the spiral grooves are threaded with bolts.

[0009] Furthermore, as a preferred embodiment of this utility model, the surfaces of the first fixing block and the first sliding groove are provided with a first sealing groove, and the inner cavity of the first sealing groove is provided with a first sealing ring. The surfaces of the well shaft and the second locking block are provided with a second sealing groove, and the surface of the second sealing groove is fitted with a second sealing ring.

[0010] Furthermore, as a preferred embodiment of this utility model, a connecting block is fixedly connected to the bottom of the first fixing block, and the connecting block is disposed in the inner cavity of the mounting groove.

[0011] Beneficial effects: The technical solution of this application has the following advantages: This utility model has a more stable combined structure and effectively prevents water seepage. In actual use, through the cooperation of the first fixing block, the first sliding groove, the first spring, the limiting block, the second fixing block, and the first locking block, a stable connection and installation between the first fixing block and the second fixing block can be achieved. This not only ensures the tight connection of the fixing blocks but also effectively improves the stability and anti-interference ability during the assembly process. While the spiral groove and bolts are used together, the first sealing groove and the first sealing ring work together to effectively enhance the connection and sealing between the first fixing block and the second fixing block when the well casing is spliced, thereby effectively preventing water seepage. The high elasticity of the first sealing ring ensures that even under changes in stress conditions or temperature... Even under fluctuating temperatures, it maintains excellent sealing performance. Through the coordinated use of the well casing, mounting groove, fixing sleeve, second locking block, second sliding groove, snap-fit ​​mechanism, second sealing groove, second sealing ring, and connecting block, the well casing can be quickly and stably assembled, simplifying the installation process and ensuring a firm connection and seal between each part. With the synergistic effect of the second locking block, second sliding groove, and snap-fit ​​mechanism, the well casing can be firmly connected to the fixing sleeve, enhancing the overall structure's seismic and compressive resistance. The first sealing ring and second sealing groove work together to further improve the connection stability between the well casing and the fixing sleeve, ensuring that water leakage is unlikely during long-term use. This not only improves durability and safety but also guarantees long-term reliability in complex environments.

To better understand the technical content of the present utility model, specific embodiments are provided and described in conjunction with the accompanying drawings. Various aspects of the present utility model are described in this disclosure with reference to the accompanying drawings, which show many illustrative embodiments. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways.

[0016] As attached Figure 1 To be continued Figure 8 As shown: This embodiment provides a combined caisson for agricultural water supply, including a well shaft 1. The top of the well shaft 1 has an installation groove 2. The top of the well shaft 1 is provided with a first fixing block 3. The surface of the first fixing block 3 is provided with a plurality of first sliding grooves 4. The inner cavity of each of the plurality of first sliding grooves 4 is fixedly connected with a first spring 5. The other end of the first spring 5 is fixedly connected with a limit block 6, and the limit block 6 is slidably connected to the inner cavity of the first sliding groove 4. The top of the first fixing block 3 is provided with a second fixing block 7. The bottom of the second fixing block 7 is fixedly connected with a plurality of first locking blocks 8. One side of the first locking block 8 is locked into the inner cavity of the first sliding groove 4 and contacts the limit block 6. The top of the second fixing block 7 is fixedly connected with a fixing sleeve 9. The inner cavity of the fixing sleeve 9 is fixedly connected with a plurality of second locking blocks 10 arranged in a circular array. The bottom of the well shaft 1 is provided with a plurality of second sliding grooves 11. The inner cavity of each of the plurality of second sliding grooves 11 is provided with a locking mechanism 12, and one side of the locking mechanism 12 contacts the second locking block 10.

[0017] Specifically, the locking mechanism 12 includes a second spring 121 fixedly connected to the inner cavity of the second slide groove 11, and a slide rod 122 fixedly connected to the other end of the second spring 121. One end of the slide rod 122 is locked to the second locking block 10.

[0018] In this embodiment, the snap-fit ​​mechanism 12 enables a tight connection between the fixed sleeve 9 and the well casing 1, ensuring the stability of the fixed sleeve 9 and the well casing 1 during the splicing process and effectively preventing relative slippage or loosening of the two due to external forces during use.

[0019] Specifically, the surfaces of the first fixing block 3 and the first sliding groove 4 are provided with a number of spiral grooves 13, and the surfaces of the spiral grooves 13 are threaded with bolts 14.

[0020] In this embodiment, the use of the spiral groove 13 and the bolt 14 together can further strengthen the connection between the first fixing block 3 and the first sliding groove 4. The bolt 14, through the tightening action of the thread, firmly presses the two together, thereby effectively improving the stability and tensile strength of the connection. This not only ensures the high strength fixation of the structure, but also maintains a firm connection under changes in the external environment, avoiding any loosening or deformation.

[0021] Specifically, the surfaces of the first fixing block 3 and the first sliding groove 4 that are in contact with each other are provided with a first sealing groove 15, and the inner cavity of the first sealing groove 15 is provided with a first sealing ring 16. The surfaces of the well shaft 1 and the second locking block 10 that are in contact with each other are provided with a second sealing groove 17, and the surface of the second sealing groove 17 is fitted with a second sealing ring 18.

[0022] In this embodiment, the combined use of the first sealing groove 15 and the first sealing ring 16, and the second sealing groove 17 and the second sealing ring 18, effectively prevents water penetration, thereby ensuring the stability and sealing of the connection. The first sealing ring 16 and the second sealing ring 18 undergo elastic deformation during splicing, filling the tiny gaps between the contact surfaces to form a tight sealing structure, preventing the penetration of groundwater or surface water, ensuring the watertightness of the well shaft 1 splice, and avoiding the erosion of the connection by water flow or the negative impact on the overall structural stability.

[0023] Specifically, a connecting block 19 is fixedly connected to the bottom of the first fixing block 3, and the connecting block 19 is set in the inner cavity of the mounting groove 2.

[0024] In this embodiment: the connection block 19 enables precise and tight contact between the well shaft 1 and the connection block 19, thereby ensuring a firm combination between the well shaft 1 and the connection block 19. The connection block 19, through its specific structural shape and interface design, is tightly connected to the surface of the well shaft 1 to form a stable connection, avoiding any loosening or displacement.

[0025] The working principle and usage process of this utility model are as follows: When splicing the well casing 1, the first fixing block 3 is first embedded into the mounting groove 2 at the top of the well casing 1 through the bottom connecting block 19, completing the initial positioning of the first fixing block 3 and the well casing 1. Then, the second fixing block 7 is installed, and the first locking block 8 at its bottom is aligned with the first sliding groove 4 on the surface of the first fixing block 3 and inserted. The first locking block 8 presses the limiting block 6 in the first sliding groove 4, causing the limiting block 6 to compress the first spring 5. When the first locking block 8 is fully inserted into the first sliding groove 4, the first spring 5 returns to its original position and pushes the limiting block 6 to resist the first locking block 8 in the opposite direction, forming an initial locking connection, realizing the axial positioning of the first fixing block 3 and the second fixing block 7. At the same time, the fixing sleeve 9 at the top of the second fixing block 7 is installed synchronously with the second fixing block 7. The second locking block 10 on the surface of the fixing sleeve 9 corresponds to the second sliding groove 11 at the bottom of the well casing 1. In the locking mechanism 12 in the second sliding groove 11, the sliding rod 122 is in the spring of the second spring 121. Under the action of force, it engages with the second locking block 10, further restricting the relative rotation of the fixing sleeve 9 and the well barrel 1, enhancing the overall stability after splicing. To strengthen the connection strength, bolts 14 are screwed into the spiral grooves 13 on the surfaces of the first fixing block 3 and the second fixing block 7, and the thread tightening force is used to press the two tightly together. With the double mechanical locking of the limiting block and the first locking block 8, and the first sliding groove 4 and the limiting block 6, a composite fixing structure of elastic engagement and rigid fastening is formed to prevent the splice from loosening due to water flow impact or settlement. In terms of sealing, the first sealing ring 16 in the first sealing groove 15 on the contact surface of the first fixing block 3 and the second fixing block 7, and the second sealing ring 18 in the second sealing groove 17 on the contact surface of the well barrel 1 and the second locking block 10 undergo elastic deformation under the splicing pressure, filling the gap of the contact surface, preventing groundwater or surface water from seeping from the splice joint, ensuring the overall sealing of the caisson, and meeting the waterproofing requirements in agricultural water supply scenarios.
