Abstract
Description
Technical Field
[0001] This invention relates to the technical field of greenhouse sprinkler pipe installation mechanisms, and in particular to a greenhouse sprinkler pipe fixing and installation mechanism that can be laterally slidable and adjustable. Background Technology
[0002] Greenhouse cultivation, with its controllable growing environment and seasonal advantages, has become one of the mainstream cultivation methods for cash crops such as vegetables, fruits, and flowers in my country. As a core supporting equipment in greenhouse cultivation, the sprinkler irrigation system directly determines the uniformity of crop irrigation, water resource utilization, and crop growth quality. The fixed installation structure of the sprinkler pipes is a key component affecting the ease of installation, irrigation coverage, and flexibility of use of the sprinkler system.
[0003] Currently, the conventional installation method for sprinkler pipes in greenhouses mostly adopts a fixed bracket structure. The sprinkler pipes are directly fixed to a predetermined position on the greenhouse frame through binding, welding, or bolting. After installation, the lateral position of the sprinkler pipes is completely locked and cannot be adjusted. In actual greenhouse cultivation, the greenhouse is divided into multiple planting rows according to planting needs. Different planting rows have different crop types, growth cycles, and water requirements, resulting in varying needs for sprinkler coverage and spraying positions. Fixed-installation sprinkler pipes cannot flexibly adjust the spraying position according to the actual planting situation, easily leading to localized irrigation blind spots or over-irrigation. This not only fails to meet the needs of precision irrigation for crops but also causes serious waste of water resources, affecting crop yield and quality.
[0004] To achieve full irrigation coverage within greenhouses, growers often need to install a large number of fixed sprinkler lines, sometimes even laying a separate sprinkler line for each planting row. This directly leads to a significant increase in the consumption of consumables such as pipes, fittings, and nozzles, greatly increasing system construction costs and significantly increasing the workload of pipe installation and construction, thus extending the construction period. Furthermore, the densely packed fixed pipes create a chaotic and disorganized layout within the greenhouse, not only occupying limited planting and agricultural operation space and affecting daily tasks such as pruning, harvesting, and fertilizing, but also greatly increasing the difficulty of troubleshooting and maintenance when blockages, damage, or leaks occur, thus increasing the system's long-term maintenance costs. While some mobile greenhouse sprinkler irrigation equipment has emerged in the existing technology, most of them are integrated mobile sprinkler truck structures that require a dedicated driving mechanism and special tracks. The equipment is large in size, with extremely high procurement and installation costs. Furthermore, it can only travel along a preset fixed path and cannot flexibly adjust the spraying points according to the irregular planting layout inside the greenhouse, nor can it make precise adjustments to the spraying position for local planting areas. As a result, it is difficult to adapt to the planting needs of small and medium-sized greenhouses, thus limiting its applicability and promotion. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laterally adjustable fixing and installation mechanism for greenhouse internal sprinkler pipes.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a horizontally adjustable greenhouse internal sprinkler pipe fixing and installation mechanism, including a track unit, the track unit being installed inside the greenhouse body, the greenhouse body being composed of multiple arched supports, wherein the arched supports can be inserted into the ground for fixing, and the interior of the multiple arched supports is provided with a horizontal connecting rod, the horizontal connecting rod assembling the multiple arched supports into a complete greenhouse frame, and the bottom of the track unit is provided with a fixing unit, wherein the fixing unit can move horizontally along the track unit in the horizontal direction, the fixing unit can clamp the sprinkler pipe, and water delivered by the water pump flows along the sprinkler pipe and is sprayed out from the sprinkler nozzle to water the plants inside the greenhouse.
[0007] Furthermore, the track unit includes a track steel bar, with support arms fixedly connected to both ends of the track steel bar. The sliding cavity is formed inside the track steel bar, and an adjusting screw is rotatably installed on the upper end face of the track steel bar. A vertically extending connecting rod is inserted into the internal thread of the adjusting screw, and a hook is fixedly connected to the upper end of the connecting rod. The hook is hooked onto the transverse connecting rod. Rotating the adjusting screw can drive the connecting rod to extend and retract vertically to adjust the hanging distance between the track steel bar and the transverse connecting rod, thereby adjusting the levelness and installation height of the track steel bar.
[0008] Furthermore, a positioning strip extending laterally is fixed to the upper surface of the supporting plate, and a limiting raceway is formed between the positioning strip and the top wall of the sliding cavity. The limiting raceway is used to limit the sliding stroke of the adjustment unit vertically and guide it laterally to prevent vertical movement of the adjustment unit during the sliding process.
[0009] Furthermore, the adjustment unit includes a rotating sleeve, a shaft horizontally passing through the upper part of the rotating sleeve, rollers coaxially fixed to both ends of the shaft, and a guide slider fixed to the top of the rotating sleeve. The lower end of the rotating sleeve extends downward out of the sliding cavity and is coaxially fixed to the fixing unit. The rollers are embedded in the limiting raceway, and the wheel surface of the rollers rolls against the inner wall of the limiting raceway, allowing them to roll laterally along the limiting raceway. A horizontally arranged reinforcing plate is fixed inside the sliding cavity, and a track groove extending laterally is opened through the reinforcing plate. The guide slider is inserted upward into the track groove and can slide laterally along the track groove to provide secondary guidance for the sliding path of the rotating sleeve and prevent circumferential deflection during the sliding process.
[0010] Furthermore, the guide slider has mounting grooves on both sides facing the inner wall of the track groove. A clamping roller is rotatably mounted in the mounting groove. The axis of the clamping roller is perpendicular to the extension direction of the track groove. The wheel surface of the clamping roller rolls against the inner wall of the track groove to convert the sliding friction between the guide slider and the track groove into rolling friction, thereby reducing the adjustment resistance of lateral sliding.
[0011] Furthermore, the roller has an annular groove on its circumference, and the inner bottom wall of the annular groove has multiple sets of radially extending mounting grooves. A pressing block is slidably connected in the mounting groove, and an extension spring is provided between the pressing block and the bottom of the mounting groove. Under normal conditions, the elastic force of the extension spring drives the pressing block to extend radially out of the mounting groove, so that the outer end of the pressing block presses against the inner wall of the limiting raceway, forming a radial lock on the roller, preventing the fixing unit from being displaced unexpectedly by external force. When a lateral thrust is applied, the pressing block compresses the extension spring and retracts radially into the mounting groove, releasing the lock on the roller, allowing the roller to roll freely along the limiting raceway, thus completing the lateral position adjustment of the fixing unit.
[0012] Furthermore, the fixing unit includes a vertical pull rod, the upper end of which is coaxially fixed to the adjusting unit. Multiple sets of clamping parts are evenly arrayed along the circumference of the vertical pull rod. Each set of clamping parts includes a clamping arm fixed to the side wall of the vertical pull rod and an elastic strip fixed to the bottom of the vertical pull rod. The elastic strip bends upward and extends into the gap between the clamping arm and the vertical pull rod. The elastic strip can elastically expand outward along the radial direction of the vertical pull rod and cooperate with the clamping arm to form a clamping cavity for accommodating the spray pipe.
[0013] Furthermore, a first clamping pad is fixedly connected to the side of the clamping arm facing the elastic strip, and a second clamping pad is fixedly connected to the side of the elastic strip facing the clamping arm. Both the first and second clamping pads have arc-shaped recesses on their opposite surfaces. The axis of the arc-shaped recesses is perpendicular to the axis of the vertical pull rod, so as to form a surface fit with the outer wall of the spray pipe for clamping. Both the first and second clamping pads are rubber pads, which are used to increase the friction coefficient with the outer wall of the spray pipe and prevent the spray pipe from axially moving under clamping conditions.
[0014] Furthermore, a spreading part is provided between the vertical tie rod and the elastic strip. The spreading part includes a telescopic guide rod arranged radially and a clamping spring sleeved on the outside of the telescopic guide rod. The fixed end of the telescopic guide rod is fixedly connected to the side wall of the vertical tie rod, and the telescopic end of the telescopic guide rod abuts against the inner side wall of the elastic strip. The two ends of the clamping spring abut against the vertical tie rod and the elastic strip respectively. The elastic force of the clamping spring drives the telescopic guide rod to extend radially, pushing the elastic strip to expand radially outward toward the clamping arm side, so that the first clamping pad and the second clamping pad simultaneously clamp the outer wall of the spray pipe to form a stable clamping.
[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, the horizontally sliding track unit and the adjustment unit work together to achieve stepless and flexible adjustment of the horizontal position of the sprinkler pipe, which can accurately adapt to the sprinkler needs of different planting ridges and different types of crops in the greenhouse. This solves the problems of fixed irrigation range of traditional fixed-installation sprinkler pipes, which cannot be flexibly adjusted, and require a large number of additional pipelines, resulting in high system construction costs and messy pipeline layout.
[0016] 2. In this invention, the adjustment unit adopts a rolling friction design of roller rolling and clamping roller, which greatly reduces the adjustment resistance of lateral sliding, making operation effortless and smooth, without jamming or sticking. At the same time, through the secondary guiding structure of guide slider and track groove, the sliding path can be precisely constrained, avoiding circumferential deflection of rotating sleeve and fixed unit during adjustment.
[0017] 3. In this invention, the roller has a built-in spring-driven compression block locking structure. Under normal conditions, the elastic force of the extension spring can automatically press against the inner wall of the limiting roller, forming a radial lock on the roller. This effectively avoids the pipeline from being impacted by water flow or disturbed by external forces during the spraying operation, thus ensuring the fixation of the spraying position.

Detailed Implementation
[0020] Example 1, as Figure 1-7As shown, a laterally adjustable sprinkler pipe fixing and installation mechanism for a greenhouse includes multiple sets of arched supports 1 evenly spaced along the longitudinal direction of the greenhouse. The lower ends of the multiple sets of arched supports 1 are vertically inserted into the planting ground inside the greenhouse. Adjacent arched supports 1 are fixedly connected by multiple transverse connecting rods 2 extending along the longitudinal direction of the greenhouse. The multiple sets of arched supports 1 and multiple transverse connecting rods 2 are spliced together to form a stable and complete greenhouse frame, providing a stable support base for the installation of the track unit 4. The track unit 4 is arranged along the transverse direction of the greenhouse. The track unit 4 includes a track steel bar 41, which is manufactured using an integral bending forming process. The track steel bar 41 has a downward-facing sliding cavity formed inside. The inner walls on both sides of the bottom of the sliding cavity are bent inward horizontally to form support plates. Support arms 3 are fixedly connected to both ends of the track steel bar 41. The upper ends of the support arms 3 can be fixedly connected to the corresponding positions of the greenhouse frame to achieve auxiliary positioning of the track steel bar 41, further improving the overall structural stability of the track unit 4 after installation. Multiple sets of hanging adjustment components are installed at horizontal intervals on the upper end face of the track steel bar 41. Each set of hanging adjustment components includes an adjusting screw 9 rotatably installed on the upper end face of the track steel bar 41. A rotation limit structure is provided between the bottom of the adjusting screw 9 and the upper end face of the track steel bar 41 to prevent vertical movement of the adjusting screw 9 during rotation. A vertically upward extending connecting rod 7 is inserted into the internal thread of the adjusting screw 9. A hook 8 is fixedly connected to the upper end of the connecting rod 7. The hook 8 is provided with an anti-detachment closure structure and can be directly hooked onto the horizontal connecting rod 2 of the greenhouse frame to realize the suspended installation of the track unit 4 inside the greenhouse and prevent the hook 8 from accidentally falling off the horizontal connecting rod 2 due to external disturbance. A positioning strip 42 extending transversely along the entire length of the track steel strip 41 is fixedly connected to the upper surface of the support plate. The bottom surface of the positioning strip 42 is completely fitted and fixed to the upper surface of the support plate to ensure the structural strength after connection. A limiting raceway is formed between the upper surface of the positioning strip 42 and the top wall of the sliding cavity. The limiting raceway is used to provide guidance and constraint for the transverse sliding of the adjustment unit 6 and vertical limiting protection to prevent vertical movement and jamming of the adjustment unit 6 during the sliding process. The adjustment unit 6 is fully embedded inside the sliding cavity of the track steel bar 41. The adjustment unit 6 includes a rotating sleeve 61, and a shaft 62 is horizontally inserted through the upper part of the rotating sleeve 61. A rotating fit structure is provided between the shaft 62 and the rotating sleeve 61 to ensure the stable rotation of the shaft 62. Both ends of the shaft 62 extend out of the rotating sleeve 61 and are coaxially fixedly connected to rollers 63. The two rollers 63 are respectively embedded in the limiting raceways on both sides of the track steel bar 41. The circumferential surface of the rollers 63 rolls and fits against the upper and lower inner walls of the limiting raceways, so that the rollers 63 can roll freely laterally along the extension direction of the limiting raceways, thereby driving the adjustment unit 6 to complete the lateral position adjustment.A vertically upward-extending guide slider 64 is fixedly connected to the top of the rotating sleeve 61. The guide slider 64 and the rotating sleeve 61 are integrally molded to ensure the strength of the connection structure. A horizontally arranged reinforcing plate 43 is fixedly connected inside the sliding cavity. Both ends of the reinforcing plate 43 are completely fixedly connected to the inner walls of both sides of the sliding cavity, which can further improve the overall deformation resistance of the track steel bar 41. The reinforcing plate 43 is located above the limiting raceway. A track groove 44 extending horizontally along the entire length is opened through the middle of the reinforcing plate 43. The upper end of the guide slider 64 is inserted into the interior of the track groove 44. The left and right side walls of the guide slider 64 slide against the left and right inner walls of the track groove 44, so that the guide slider 64 can slide horizontally synchronously along the extension direction of the track groove 44, providing secondary guidance and constraint for the sliding path of the rotating sleeve 61, and preventing the rotating sleeve 61 from circumferentially deflecting during the sliding process. The guide slider 64 has mounting slots 65 on both the left and right sides facing the inner wall of the track groove 44. Each mounting slot 65 has a clamping roller 66 rotatably mounted inside it. Both ends of the clamping roller 66 are provided with axial limiting structures to prevent the clamping roller 66 from coming out of the mounting slot 65 during rotation. The axis of the clamping roller 66 is perpendicular to the extension direction of the track groove 44. The outer circumferential surface of the clamping roller 66 rolls against the corresponding inner wall of the track groove 44, converting the sliding friction between the guide slider 64 and the track groove 44 into rolling friction, which greatly reduces the motion resistance of the adjustment unit 6 during the lateral sliding process. A ring groove 67 is formed in the middle of the circumference of the roller 63. Multiple sets of assembly grooves 68 are evenly formed in the inner bottom wall of the ring groove 67 along the radial direction of the roller 63. An extrusion block 69 is slidably connected inside each assembly groove 68. An inward limiting structure is provided at the groove opening of the assembly groove 68 to prevent the extrusion block 69 from completely coming out of the assembly groove 68 during sliding. An extension spring is provided between the extrusion block 69 and the bottom of the assembly groove 68. The two ends of the extension spring are fixedly connected to the bottom of the assembly groove 68 and the inner end of the extrusion block 69, respectively, to ensure that the elastic force is stably output along the radial direction of the roller 63. The lower end of the rotating sleeve 61 extends downwards out of the bottom opening of the sliding cavity. The lower end of the rotating sleeve 61 is coaxially fixedly connected to a fixing unit 5. The fixing unit 5 includes a vertically arranged vertical pull rod 51. The upper end of the vertical pull rod 51 is coaxially fixedly connected to the lower end of the rotating sleeve 61, which can ensure the stable transmission of lateral thrust and avoid torque deviation during the application of force. Multiple clamping parts are evenly arranged in a circumferential array on the circumferential side wall of the vertical pull rod 51, which can simultaneously meet the synchronous clamping and fixing requirements of multiple spray pipes.Each clamping unit includes a clamping arm 52 fixedly connected to the side wall of the vertical pull rod 51, and an elastic strip 54 fixedly connected to the bottom of the vertical pull rod 51. The elastic strip 54 is made of a material with good elastic deformation ability, which can ensure that it can maintain stable elastic restoring ability after long-term repeated opening and closing. The lower end of the elastic strip 54 is fixedly connected to the bottom end of the vertical pull rod 51, and the upper end of the elastic strip 54 bends upward and extends into the gap between the clamping arm 52 and the vertical pull rod 51. The elastic strip 54 can undergo elastic deformation along the radial direction of the vertical pull rod 51 under the action of external force, thereby adjusting the clamping gap between it and the clamping arm 52. A first clamping pad 53 is fixedly connected to the side surface of the clamping arm 52 facing the elastic strip 54, and a second clamping pad 55 is fixedly connected to the side surface of the elastic strip 54 facing the clamping arm 52. The opposing surfaces of the first clamping pad 53 and the second clamping pad 55 are both provided with arc-shaped recesses. The axis of the arc-shaped recesses is perpendicular to the axis of the vertical pull rod 51, which can form a stable surface fit and clamp with the outer wall of the spray pipe with different outer diameter specifications. The first clamping pad 53 and the second clamping pad 55 are both made of wear-resistant and non-slip rubber material, which can greatly improve the frictional force between them and the outer wall of the spray pipe. A spreading part is provided between the side wall of the vertical tie rod 51 and the inner side wall of the elastic strip 54. The spreading part includes a telescopic guide rod 56 arranged radially along the vertical tie rod 51. The fixed end of the telescopic guide rod 56 is fixedly connected to the side wall of the vertical tie rod 51, and the telescopic end of the telescopic guide rod 56 abuts against the inner side wall of the elastic strip 54. The telescopic guide rod 56 is provided with a limiting structure for the maximum telescopic stroke, which can prevent the telescopic end from coming out of the fixed end. A clamping spring 57 is sleeved on the outside of the telescopic guide rod 56. The two ends of the clamping spring 57 abut against the side wall of the vertical tie rod 51 and the inner side wall of the elastic strip 54, respectively, which can provide a continuous and stable radial spreading force for the elastic strip 54.
[0021] The working principle is as follows: First, based on the planting layout and sprinkler requirements inside the greenhouse, determine the installation position and lateral extension length of the track unit 4. The track steel bar 41 is then suspended from the corresponding lateral connecting rod 2 in the greenhouse using hooks 8. The anti-detachment closure structure of the hooks 8 ensures that it will not accidentally fall off the lateral connecting rod 2 while suspended. Rotating the adjusting screw 9 drives the connecting rod 7 to extend and retract vertically via the threaded connection, thereby adjusting the installation height and level of the track steel bar 41. This, combined with the support arms 3 at both ends of the track steel bar 41, ensures the stable installation of the track unit 4, preventing deformation of the track steel bar 41 during long-term use and ensuring smooth sliding adjustment. When it is necessary to clamp and fix the sprinkler pipe, press the elastic bar 54 inward to cause the clamping spring 57 and the telescopic guide rod 56 to retract synchronously, increasing the clamping gap between the elastic bar 54 and the clamping arm 52. After placing the sprinkler pipe to be installed into the corresponding clamping gap, release the elastic bar 54. The reset force of the clamping spring 57 pushes the telescopic guide rod 56 to extend radially, simultaneously causing the elastic strip 54 to open and close radially outward. This ensures that the arc-shaped recesses of the first clamping pad 53 and the second clamping pad 55 are tightly fitted against the outer wall of the spray pipe. The anti-slip and wear-resistant properties of the rubber material significantly increase the friction of the clamping contact surface. Combined with multiple circumferentially arranged clamping parts, stable clamping and fixing of single or multiple spray pipes can be achieved, preventing axial movement or radial swaying of the spray pipes during water spraying. When it is necessary to adjust the lateral spraying position of the spray pipe, a smooth lateral thrust is applied to the vertical pull rod 51. This thrust is synchronously transmitted to the rollers 63 at both ends and the guide slider 64 at the top via the coaxially fixed rotating sleeve 61. The radial component of the lateral thrust causes the extrusion block 69 to compress the elongation spring and retract into the assembly groove 68, releasing the locking state between the roller 63 and the limiting raceway. At this time, the roller 63 can roll freely laterally along the limiting raceway, while the guide slider 64 slides synchronously along the track groove 44 on the reinforcing plate 43. The clamping rollers 66 on both sides of the guide slider 64 can convert sliding friction into rolling friction, greatly reducing the motion resistance during the sliding process. This drives the fixing unit 5 and the clamped and fixed spray pipe to complete the lateral position adjustment synchronously, which can flexibly adapt to the spraying operation needs of different planting ridges and different types of crops in the greenhouse. After the position adjustment is completed, the lateral thrust is removed, and the restoring force of the elongation spring pushes the extrusion block 69 to extend radially out of the assembly groove 68, so that the outer end of the extrusion block 69 is stably pressed against the inner wall of the limiting raceway, forming a radial locking limit on the roller 63. The locked state prevents the sprinkler pipe from undergoing unexpected lateral displacement due to water flow impact, wind disturbance, or other external forces during spraying operations, ensuring the stability of the spray position and the uniformity of the spraying operation. The reinforcing plate 43 inside the track steel bar 41 further enhances the overall structural strength of the track unit 4, preventing deformation during long-term use and ensuring the long-term smoothness of sliding adjustment. The telescopic guide rod 56 guides and constrains the telescopic path of the clamping spring 57, preventing radial bending failure of the clamping spring 57 during long-term repeated compression and reset, and ensuring the long-term stable output of clamping force.The high elasticity of the 54 elastic strip ensures that it can maintain a stable clamping force even after repeated disassembly and reassembly, thus improving the service life and stability of the entire mechanism.
