Description

Technical Field

[0001] This utility model relates to the field of anti-settlement technology for agricultural greenhouse columns, and in particular to an adjustment structure for preventing the settlement of agricultural greenhouse columns. Background Technology

[0002] As a core facility for modern, efficient agricultural production, the stability and durability of the overall structure of agricultural greenhouses are of paramount importance. The greenhouse's skeletal system consists of numerous columns as the main load-bearing and supporting units. The consistency and stability of the vertical height of these columns directly determine the flatness of the greenhouse roof and the proper functioning of internal irrigation and drainage systems.

[0003] In existing greenhouse construction techniques, supporting columns are mostly made of integral metal pipes or cement components. Installation typically involves burying the lower end of the column directly into compacted soil or casting it onto a pre-excavated concrete foundation. After installation, the top of the column is rigidly connected to the greenhouse's beams, trusses, or drainage troughs using welded brackets, U-bolts, or flanges. This traditional design philosophy involves precisely determining the elevation of all columns during the initial construction phase, with all connections being permanent or semi-permanent. The long-term levelness of the entire greenhouse structure depends entirely on the initial stability and sustained bearing capacity of the foundation.

[0004] However, in actual use, due to the large area occupied by greenhouses, it is difficult to ensure that the foundation conditions under all columns are completely uniform. Uneven settlement of the column foundation is a very common phenomenon due to various complex factors such as natural soil compaction, seasonal freeze-thaw cycles, groundwater level changes, or uneven irrigation. Once individual or localized columns settle, it directly damages connected components such as water channels and guide rails that require precise leveling, leading to poor irrigation flow, localized water accumulation, or abnormal stress on the greenhouse film, accelerating its aging and damage. Existing technologies for dealing with such problems are very passive and cumbersome. They typically require excavating the soil around the settled column, using jacks or other equipment to lift the column back to its original position, and then reinforcing it by placing stones, steel plates, or re-filling cement mortar at its base. This repair method is labor-intensive, inefficient, and costly, and it also interferes with the normal use of the greenhouse. Therefore, a regulating structure for preventing agricultural greenhouse column settlement is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustment structure for preventing the settlement of agricultural greenhouse columns. It aims to improve the situation where agricultural greenhouse columns are prone to settlement due to uneven foundations, which can disrupt the level of water channels, leading to poor irrigation and damage to the greenhouse film. Existing repair methods require excavation and jacking, which is not only costly and inefficient but also interferes with normal use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustment structure for preventing settlement of agricultural greenhouse columns, comprising:

[0007] The column body has a nut sleeve installed on the inner wall at its upper end;

[0008] A short rod is provided with an external thread on the lower outer wall that mates with the nut sleeve. The short rod is adjustablely installed on the upper end of the column body through the threaded connection between the external thread and the nut sleeve.

[0009] The integrated water card bracket is fixedly connected to the upper end of the reserved short rod;

[0010] And a water tank with integrated water card, which is set and housed inside the integrated water card bracket;

[0011] Both the column body and the reserved short rod have reserved holes inside. The column body and the reserved short rod are secondary limited by limiting bolts and limiting nuts passing through the reserved holes.

[0012] As a further description of the above technical solution:

[0013] It also includes a waterproof gasket, which is disposed between the inner wall of the integrated water card bracket and the outer wall of the integrated water card tank.

[0014] As a further description of the above technical solution:

[0015] Both the integrated water card bracket and the integrated water card tank have corresponding through holes one and two. The structure also includes fixing bolts for passing through the through holes one and two, and fixing nuts that cooperate with the fixing bolts to lock them in place. The fixing bolts and fixing nuts clamp and fix the integrated water card bracket and the integrated water card tank.

[0016] As a further description of the above technical solution:

[0017] The structure also includes a flat washer and a waterproof cardboard washer; the head of the fixing bolt is fitted with a flat washer and a waterproof cardboard washer in sequence, and the waterproof cardboard washer abuts against the inner wall of the integrated water tank.

[0018] As a further description of the above technical solution:

[0019] The water card integrated bracket has a U-shaped cross-section and is used to support the water card integrated water tank.

[0020] As a further description of the above technical solution:

[0021] The rotation of the column body allows it to be displaced axially relative to the reserved short rod, thereby adjusting the vertical height of the integrated water tank.

[0022] As a further description of the above technical solution:

[0023] The waterproof pad is made of elastic material and completely fills the gap between the integrated water card bracket and the integrated water card tank.

[0024] As a further description of the above technical solution:

[0025] The reserved short rod and the integrated water card bracket are either welded together or integrally formed.

[0026] This utility model has the following beneficial effects:

[0027] 1. This utility model provides a convenient, efficient, and low-cost solution for greenhouse column settlement compensation by setting a threaded adjustment mechanism between the column body and the reserved short rod. When the columns of an agricultural greenhouse sink due to foundation settlement, soil loosening, or other reasons, there is no need to re-excavate or raise the columns. Simply rotating the nut sleeve utilizes the relative movement between the nut sleeve and the external thread of the reserved short rod to achieve vertical height adjustment of the reserved short rod and the integrated water trough at the upper end. Simultaneously, after the limiting bolt passes through the reserved hole, the reserved short rod is further fixed by the limiting nut to prevent sinking. This adjustment method is simple to operate, precise, and can quickly restore the level of the greenhouse water trough or components. It effectively solves problems such as uneven irrigation and abnormal stress on the greenhouse film caused by uneven column settlement, significantly improving the long-term stability and usability of the greenhouse structure.

[0028] 2. In this utility model, a stable and highly sealed load-bearing system is constructed through the combination of an integrated water card bracket, a waterproof gasket, an integrated water card trough, and fasteners. The U-shaped integrated water card bracket provides stable and reliable physical support for the water trough, while the elastic waterproof gasket filling the space between the two acts as a buffer and provides initial sealing. More importantly, the fixing bolts and nuts are used to lock the water trough and bracket together, and a waterproof cardboard gasket is placed below the head of the fixing bolt on the inside of the water trough. This gasket ensures the tightening force while effectively sealing the fixing bolt holes, which are most prone to leakage, thus forming a double waterproof guarantee. This design ensures the firmness of the water trough connection and completely eliminates the risk of leakage at the joints and fastening points, ensuring the dryness of the greenhouse environment and the safety of the facilities.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figures 1-5 One embodiment of this utility model provides: an adjustment structure for preventing settlement of agricultural greenhouse columns, comprising:

[0038] The main support column 11 of the greenhouse has a nut sleeve 12 machined on its upper inner wall for threaded transmission.

[0039] A reserved short rod 13, which serves as the core of height adjustment, has an external thread 10 on its lower outer wall that mates with the nut sleeve 12. The reserved short rod 13 is connected to the nut sleeve 12 via the external thread 10 and is adjustablely installed on the upper end of the column body 11.

[0040] A water card integrated bracket 1 for supporting the water tank, the water card integrated bracket 1 being securely fixed to the upper end of the reserved short rod 13;

[0041] The system includes a water-card integrated tank 3 for conveying or collecting fluid, which is directly installed and housed inside the water-card integrated bracket 1. Both the column body 11 and the reserved short rod 13 have reserved holes 14, which are then secondary-limited by limiting bolts 16 and limiting nuts 15 passing through the reserved holes 14. The structure also includes a waterproof gasket 2 for sealing and buffering, positioned between the inner wall of the water-card integrated bracket 1 and the outer wall of the water-card integrated tank 3. For a secure connection, both the water-card integrated bracket 1 and the water-card integrated tank 3 have corresponding through holes 8 and 9 for fasteners to pass through. The structure also includes fixing bolts 4 for passing through the through holes 8 and 9, and fixing nuts 7 that engage with and lock the fixing bolts 4. The fixing bolts 4 and 7, through clamping force, secure the water-card integrated bracket 1... The integrated water tank 3 is fixed as a whole; the structure also includes a flat gasket 5 and a waterproof cardboard gasket 6 for dispersing the tightening pressure and enhancing the seal; the flat gasket 5 and the waterproof cardboard gasket 6 are sequentially fitted under the head of the fixing bolt 4, and the waterproof cardboard gasket 6 tightly abuts against the inner wall of the integrated water tank 3 to seal the gaps; to achieve stable support, the cross-section of the integrated water tank 1 is U-shaped to stably support the integrated water tank 3; by rotating the column body 11, it can be displaced axially relative to the reserved short rod 13, thereby realizing convenient adjustment of the vertical height of the integrated water tank 3; the waterproof gasket 2 is made of elastic material, which can be compressed and completely filled in the gap between the integrated water tank 1 and the integrated water tank 3, ensuring the sealing effect; to ensure structural strength and connection reliability, the reserved short rod 13 and the integrated water tank 1 are welded or integrally formed.

[0042] Specifically, when it is necessary to compensate for column settlement, the rotational motion is converted into precise vertical linear displacement by rotating the column body 11 and utilizing the threaded pair between it and the reserved short rod 13. This allows for convenient adjustment of the absolute height of the integrated water tank 3 without moving or disassembling the upper components such as the water tank. Simultaneously, the integrated water tank 3 is provided with stable support by the integrated water tank bracket 1, and a double seal is formed by the waterproof gasket 2 between them and the waterproof cardboard gasket 6 at the fastening point of the fixing bolt 4, effectively preventing the risk of leakage.

[0043] Working principle: When this adjustment structure is needed, firstly, by rotating the nut sleeve 12, the reserved short rod 13 is screwed into the nut sleeve 12 of the column body 11 through its external thread 10, adjusting to the initial design height. Then, by passing the limiting bolt 16 through the reserved hole 14 inside the column body 11 and the reserved short rod 13, and then fixing the limiting bolt 16 with the limiting nut 15, a further fixing effect is achieved. The water card integrated bracket 1, as the upper extension of the reserved short rod 13, is fixedly connected to it. Subsequently, the waterproof rubber pad 2 is placed inside the water card integrated bracket 1, and then the water card integrated water tank 3 is placed on the waterproof rubber pad 2. Finally, the fixing bolt 4 with the flat washer 5 and the waterproof cardboard pad 6 is passed through the through hole 9, the waterproof rubber pad 2, and the through hole 8 of the water card integrated water tank 3 from the inside, and tightened from the outside with the fixing nut 7, thereby firmly integrating the water tank, rubber pad, and bracket into one unit.

[0044] If, after the greenhouse has been operating for a period of time, ground subsidence causes the support column 11 to sink, thereby lowering the height of the integrated water tank 3, the operator does not need to disassemble any parts. Simply apply a rotational force to the support column 11. Because the reserved short rod 13 and the entire water tank assembly above it are restricted from rotation due to the load, the support column 11 will move upwards or downwards along the threads of the reserved short rod 13. By rotating in a specific direction, the position of the support column 11 relative to the reserved short rod 13 can be changed, thereby precisely adjusting the height of the integrated water tank 3 back to the predetermined horizontal position to compensate for the effects of ground subsidence.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
