Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a ridge-type automatic hail protection net system. Background Technology
[0002] In modern agricultural planting, orchards are often damaged by extreme weather such as hail, which seriously affects the quality and yield of the fruit and causes huge economic losses to fruit farmers.
[0003] In current technologies, the installation and retrieval of hail nets in orchards primarily rely on manual labor. Fruit farmers must repeatedly move around the orchard, manually deploying and retracting the nets. This is not only labor-intensive and time-consuming, but also inefficient, failing to meet the need for rapid response in large-scale orchard operations. Furthermore, manual emergency response is slow; in the face of sudden extreme weather, farmers often lack the time to deploy the nets, leading to severe damage to fruit trees within a short period. Additionally, traditional hail nets suffer from poor structural stability, easily collapsing or deforming under strong winds and heavy rain, failing to provide continuous and reliable protection for the orchard. Therefore, there is an urgent need to design an intelligent system capable of automatically controlling hail nets to adapt to complex and changing climatic conditions. Utility Model Content

[0026] In related technologies, a typical method for dealing with sudden hail disasters is to manually pull hail nets for protection. This method is labor-intensive, inefficient, and unsuitable for large-area greenhouse operations. Another method is to use mechanized hail net devices for protection, but this usually requires multiple sets of drive equipment. This method has higher manufacturing costs, more complex control, and higher maintenance difficulties and costs in the later stages.
[0027] Regarding the problems in related technologies, such as Figure 1 , Figure 2 As shown, this embodiment provides a ridge-type automatic hail suppression net system, including a main frame 10, a drive device 20, a transmission shaft 30, and an electrical control unit 50. The main frame 10 includes multiple hail suppression units 101 arranged side by side along its width direction. Each hail suppression unit 101 includes multiple hail suppression components 102 arranged along the length direction of the main frame 10, and the hail suppression components 102 are slidably connected to the main frame 10. The drive device 20 is connected to the main frame 10 and is located at one end of the main frame 10 in the length direction. The transmission shaft 30 is rotatably mounted on the main frame 10 and is connected to the output end of the drive device 20 to rotate under the drive of the drive device 20. The electrical control unit 50 is electrically connected to the drive device 20 to control the operation of the drive device 20. Each hail suppression unit 101 is provided with a transmission component 40, which is connected to the transmission shaft 30 to drive each hail suppression component 102 in each hail suppression unit 101 to operate under the action of the drive device 20. The hail net 1021 system is used to prevent crops from being damaged by natural disasters such as hail. In this embodiment, the drive device 20 drives the transmission shaft 30 to rotate, which in turn drives the hail net component 102 to move, thereby enabling the hail net 1021 to be deployed or retracted during the movement of the hail net component 102.
[0028] Specifically, the main frame 10 is the overall structure of the greenhouse, which has a ridge-like structure. The main frame 10 is arranged in a rectangular structure to form an overall structure. An area for planting and growing crops is formed inside the main frame 10. The hail protection component 102 is located at the top of the main frame 10, so that the hail protection component 102 can move along the length direction at the top of the main frame 10.
[0029] The hail suppression component 102 includes a hail suppression net 1021. As the hail suppression component 102 moves along the length of the main frame 10, it can cause the hail suppression net 1021 to move. That is, when the hail suppression component 102 moves along the length of the main frame 10, it causes the hail suppression net 1021 to unfold or retract.
[0030] In a specific configuration, the drive device 20 is an electric motor, which is supported by the main frame 10. The output end of the electric motor is connected to the transmission shaft 30, which can drive the transmission shaft 30 to rotate. The transmission shaft 30 is driven to rotate by the drive device 20, and during the rotation, the torque can be transmitted to the hail protection component 102 through the transmission component 40. The hail protection component 102 moves along the length of the main frame 10 while the hail protection net 1021 is unfolded and retracted.
[0031] It is understandable that some greenhouses are often quite long, and excessive length can lead to redundant sections in the hail protection net 1021, reducing its stability and resulting in a longer time for the net to fully deploy, which affects the protective effect on crops. In this embodiment, multiple hail protection components 102 are provided along the length of each hail protection unit 101, that is, the area along the length is divided into multiple hail protection components 102. This reduces the area of each hail protection net 1021, improves the response speed, reduces the weight burden of each net, and avoids problems such as snagging and tangling caused by an excessively large area of the net, ensuring the stable operation of the system.
[0032] In the specific working process, the electrical control unit 50 has a controller that can issue commands to control the operation of the drive device 20. When an operation is required, the controller sends a command to the electrical control unit 50, so that the drive device 20 starts quickly after receiving the command. After the drive device 20 starts, it can drive the transmission shaft 30 to rotate, and then the transmission component 40 converts the rotational motion of the drive device 20 into the linear movement of the hail protection component 102. The linear movement of the hail protection component 102 realizes the unfolding and retraction of the hail protection net 1021.
[0033] In a specific implementation, the transmission component 40 can be one or more of a pulley and rope system, a chain drive system, or a screw drive system to convert the rotational motion of the motor into the linear movement of the hail prevention component 102.
[0034] In practice, the controller uses a conventional programmable PLC controller. The drive device 20 (such as a motor) is electrically connected to the controller, and the controller is fixedly installed in the control box. The control box is equipped with corresponding control buttons. When the control buttons are operated, they send forward or reverse control signals to the motor. After receiving the control signals, the motor drives the drive shaft 30 to rotate. At the same time, the drive wheel 41 installed on the drive shaft 30 starts to rotate, driving the traction rope 44 to move vertically up and down. The traction rope 44 changes its vertical up and down movement to horizontal reciprocating movement through the guide wheel group 422. The sliding bracket 1022 in each hail protection unit 101 is fixedly connected to the horizontal traction rope 44. One end of the hail protection net 1021 is connected to the fixed bracket 12, and the other end is connected to the sliding bracket 1022. The opening and closing of the hail protection net 1021 is achieved by the horizontal reciprocating movement of the sliding bracket 1022 along the length of each hail protection unit 101 driven by the traction rope 44.
[0035] Meanwhile, a time relay is also installed in the control box. This time relay automatically stops the power switch, limiting the travel distance and ensuring that the hail net 1021 stops automatically when it reaches a fixed position. Alternatively, a stop button can be installed in the control box, allowing the operating position of the hail net 1021 to be controlled by pressing the stop button during operation.
[0036] In conjunction with the above embodiments, such as Figure 2 As shown, the transmission assembly 40 includes a driving wheel 41, a driven wheel assembly, and a traction rope 44. The driving wheel 41 is connected to the transmission shaft 30, and the traction rope 44 passes around the driving wheel 41 and is connected to the driven wheel assembly for transmission. The hail-prevention assembly 102 is connected to the traction rope 44 so that the hail-prevention assembly 102 moves when the traction rope 44 moves. The hail-prevention assembly 102 expands and contracts through reciprocating linear movement. In this embodiment, the driving wheel 41, driven wheel, and traction rope 44 form a pulley and rope system, achieving traction on the hail-prevention assembly 102 and enabling its linear movement.
[0037] Specifically, such as Figure 2 As shown, the drive wheel 41 is mounted on the transmission shaft 30, so that the transmission shaft 30 rotates while driving the drive wheel 41 to rotate. The drive wheel 41 is connected to the driven wheel assembly by the traction rope 44, and the rotation of the drive wheel 41 drives the traction rope 44 to move, thereby realizing the linear movement of the hail prevention assembly 102.
[0038] The drive wheel 41 has an annular groove on its disc, and the traction rope 44 is wrapped around the annular groove and rotates with the driven wheel assembly. When the drive wheel 41 rotates, it drives the traction rope 44 to move along its surrounding path. The hail protection component 102 is connected to the traction rope 44, so that the hail protection component 102 moves while the traction rope 44 moves.
[0039] It is understandable that greenhouses typically have a long extension length, which makes the overall movement path of the traction rope 44 long. In this embodiment, the combination of the driving wheel 41, the driven wheel assembly, and the traction rope 44 forms a pulley and rope system, which can effectively cover a large movement path and reduce the difficulty of overall layout.
[0040] In conjunction with the above embodiments, such as Figure 2 As shown, the transmission assembly 40 includes a first driven wheel mechanism 42 and a second driven wheel 43. The first driven wheel mechanism 42 is located at one end of each hail-prevention unit 101, and the second driven wheel 43 is located at the other end of each hail-prevention unit 101. A traction rope 44 is wound between the first driven wheel mechanism 42 and the second driven wheel 43. In this embodiment, by placing the first driven wheel mechanism and the second driven wheel 43 at opposite ends in the length direction, the length of the main body frame 10 can be effectively covered, thereby achieving effective driving of the hail-prevention assembly 102.
[0041] Specifically, a single column along the length of the main frame 10 serves as a hail protection unit 101. Each hail protection unit has two ends along its length. A first driven wheel mechanism 42 is located at one end where a drive device 20 is installed. This enables rapid transmission between the first driven wheel mechanism 42 and the drive wheel 41, thereby improving transmission efficiency.
[0042] It is understood that the second driven wheel 43 is a fixed pulley, which is fixed on the main frame 10. The traction rope 44 passes around the second driven wheel 43, thereby enabling traction drive in the length direction of each hail protection unit 101.
[0043] In conjunction with the above embodiments, the first driven wheel mechanism 42 includes a guide wheel assembly 422 and a tension wheel assembly 421. The tension wheel assembly 421 is located above the driving wheel 41, and the guide wheel assembly 422 is located above the tension wheel assembly 421. The tension wheel assembly 421 includes two tension wheels spaced apart from each other, with the distance between the tension wheels being smaller than the diameter of the driving wheel 41, so that the traction rope 44 wound around the driving wheel 41 is tensioned. The traction rope 44 needs to be tensioned during traction movement to efficiently transmit torque and drive the hail protection component 102.
[0044] Specifically, the guide wheel assembly 422 includes two spaced-apart guide wheels, which are used to change the direction of movement of the traction rope 44. In actual connection, the traction rope 44 has a loop-shaped rope structure, and the entire traction rope 44 is positioned between the two tensioning wheels to bind and tighten the traction rope 44, achieving overall tension of the traction rope 44. Then, the traction rope 44 is sequentially wound around the guide wheel and the second driven wheel 43 to form an integral pulley system for the traction rope 44.
[0045] In a specific configuration, one of the two guide wheels is used to enable the traction rope 44 to be wound around and output to be associated with the second driven wheel 43, while the other guide wheel is used to reconnect the traction rope 44, so that the traction rope 44 can be wound around the driving wheel 41, the guide wheel group 422, and the second driven wheel 43 for traction.
[0046] It is understandable that in this embodiment, both unfolding and retracting the hail net 1021 are achieved through the horizontal displacement of the traction rope 44. The entire operation process is simple and easy to follow, and the switching method is convenient and quick, without the need for complex mechanical structures and cumbersome operating steps. At the same time, the ingenious design of the telescopic structure makes the storage process of the hail net 1021 more convenient and faster, saving storage space in the orchard, improving the overall user experience and work efficiency of the system, and providing strong technical support and guarantee for the efficient management of the orchard.
[0047] In some embodiments, such as Figure 1 As shown, the main frame 10 includes uprights 13, crossbeams 11, supporting ridges 14, and fixed supports 12. Multiple crossbeams 11 are spaced apart along the length of the main frame 10, and multiple fixed supports 12 are spaced apart on each crossbeam 11. The fixed supports 12 on adjacent crossbeams 11 are arranged in a one-to-one correspondence and on the same straight line. The supporting ridge 14 spans the multiple fixed supports 12 on the same straight line and connects to each fixed support 12 to form a hail protection unit 101. Each fixed support 12 is also provided with the uprights 13 for supporting the overall structure, and the uprights 13 are arranged vertically. The main frame 10 forms the outer contour structure of the entire greenhouse and can support the hail protection components 102. In this embodiment, the supporting rods provide support for the overall structure, and the crossbeams 11, supporting ridges 14, and fixed supports 12 ensure high rigidity and stability of the entire structure, enhancing the uniformity and reliability of the support and providing a stable structural foundation for the normal operation of the system.
[0048] Specifically, the upright 13 is set vertically, with one end connected to the platform or ground, and the other end connected to the crossbeam 11 and the fixed bracket 12, to effectively support the crossbeam 11, the fixed bracket 12 on the crossbeam 11, and the supporting ridge 14. This method makes the overall stress distribution more uniform and improves the stability of the overall structure.
[0049] Understandably, the spaced crossbeams 11 and the corresponding fixed supports 12 on the crossbeams 11 allow for multiple hail-prevention components 102 within each hail-prevention unit 101. This multi-unit collaborative design cleverly shortens the movement distance of each hail-prevention component 102, effectively preventing rope sagging during prolonged use and ensuring the ropes remain under ideal tension, thus significantly improving the deployment effect of the hail-prevention net 1021. When deploying the hail-prevention net 1021, the units work closely together to quickly cover the orchard; when retracting the hail-prevention net 1021, it can be orderly recovered without entanglement or jamming, ensuring the system's operational stability and reliability, and providing strong support for the orchard's immediate protection. Furthermore, a single drive device 20 can drive multiple parallel hail-prevention units 101, greatly shortening the system's operating time and significantly improving disaster response capabilities. When the orchard encounters sudden severe weather, the motor can quickly drive multiple rows of hail protection nets (1021) to deploy simultaneously, establishing a protective barrier for the orchard in the shortest possible time, minimizing damage and ensuring the safety of orchard production. This efficient design not only optimizes the system's power configuration but also enhances the orchard's emergency protection capabilities.
[0050] In conjunction with the above embodiments, each hail protection unit 101 has a fixed bracket 12 with slide rails 15 on both sides in the width direction, and the hail protection component 102 is slidably connected to the slide rails 15. The slide rails 15 make the hail protection component 102 move more stably and smoothly.
[0051] Specifically, the slide rail 15 supports the hail protection component 102 and provides stable guidance for its movement, thereby enabling the traction rope 44 to move the hail protection component 102. For example, the slide rail 15 can be a structure such as a slide bar or steel wire.
[0052] In this embodiment, since each hail protection unit 101 contains multiple hail protection components 102, each hail protection component 102 is relatively lightweight. Therefore, the slide rail 15 can be made of steel wire, that is, taut steel wires are set on both sides of the fixed support frame to form the slide rail 15. This arrangement can reduce the overall layout cost and facilitate later maintenance.
[0053] In conjunction with the above embodiments, the hail protection component 102 includes a sliding bracket 1022 and a hail protection net 1021. The sliding bracket 1022 is slidably connected to the slide rail 15. One end of the hail protection net 1021 is connected to the sliding bracket 1022, and the other end of the hail protection net 1021 is connected to the fixed bracket 12, so that the sliding bracket 1022 is slidably disposed between adjacent fixed brackets 12.
[0054] Specifically, the sliding bracket 1022 is slidably connected to the slide rail 15, the hail protection net 1021 is connected to the sliding bracket 1022, and the sliding bracket 1022 is connected to the traction rope 44, so that when the traction rope 44 moves, it drives the sliding bracket 1022 to move, and the hail protection net 1021 moves accordingly.
[0055] In the specific setup, the explosion-proof net is equipped with limit rings on both sides in the width direction. The limit rings are inserted into the slide rail 15, which makes the unfolding and retraction of the hail-proof net 1021 more stable and the movement of the entire system more stable.
[0056] In the specific connection, the sliding bracket 1022 is constructed with an "L" shape. Both ends of the sliding bracket 1022 are slidably connected to the slide rail 15, and the middle part of the sliding bracket 1022 is supported on the support ridge 14. The sliding bracket 1022 is also connected to the traction rope 44. This allows the sliding bracket 1022 to move when the traction rope 44 moves, thereby enabling the hail net 1021 to unfold and retract.
[0057] In conjunction with the above embodiments, the fixed bracket 12 is constructed as a triangular frame structure, the supporting ridge 14 is located on the top of the fixed bracket 12, and both the hail protection net 1021 and the sliding bracket 1022 are erected on the supporting ridge 14.
[0058] Specifically, the support ridge 14 has a smooth surface profile, which reduces friction on the parts in contact with the support ridge 14 and makes the movement of the hail net 1021 and the sliding bracket 1022 smoother.
[0059] The support ridge 14 can be a circular steel pipe or a circular steel wire rope structure, which can make the support ridge 14 have less friction, reduce the overall manufacturing cost, and improve the stability of the entire system operation.
[0060] Understandably, the fixed bracket 12 is constructed as a triangular frame structure, forming a ridge-like structure. Multiple fixed brackets 12 connected to the supporting ridge 14 along the same straight line form the main structure along the length of each hail protection unit 101. This design facilitates the sliding of the sliding bracket 1022 and makes its movement easier to control.
[0061] In some embodiments, the transmission assembly 40 is mounted on the upright 13. The upright 13 is located in the middle of the fixed bracket 12, which makes the overall force distribution more uniform and has good structural stability.
[0062] In this embodiment, by placing the transmission component 40 on the upright 13, the overall structural stability is improved, and the operation of the entire system is made more stable.
[0063] In some embodiments, the drive unit 20 is located in the middle of the drive shaft 30. By placing the drive unit 20 in the middle of the drive shaft 30, the drive shaft becomes a symmetrically supported beam, and the torque on the drive wheel 41 decreases linearly from the middle of the shaft to both ends, avoiding stress concentration. Furthermore, placing the drive unit 20 in the middle position makes the overall layout more rational.
[0064] Specifically, the drive device 20 is a motor, which is mounted on the upright 13 of the main frame 10. It can be supported and connected by a connecting seat or connecting bracket on the upright 13. The output end of the motor is equipped with a reducer, and the transmission shaft 30 is connected to the output end of the reducer. The motor drives the reducer to rotate and drives the transmission shaft 30 to rotate.
[0065] Through the above description of the embodiments, those skilled in the art can clearly understand that each embodiment effectively avoids the sag of the rope during long-term use through multi-unit collaborative design, ensuring that the rope is always in an ideal tension state, thereby significantly improving the deployment effect of the hail net 1021. Furthermore, the ingenious design layout of one motor driving multiple rows of fruit trees greatly shortens the system's operating time and significantly improves disaster response capabilities. Moreover, the automated control achieved through the electrical control unit 50 significantly reduces manual intervention. Fruit farmers no longer need to frequently shuttle through the orchard to manually operate the hail net 1021; they only need to send commands through the electrical control unit 50, and the system can automatically complete the deployment and retraction of the hail net 1021, greatly improving the efficiency of orchard management. Furthermore, the entire system has a simple structure and is easy to control, reducing operating and management costs and maintenance difficulty.
