Description

Technical Field

[0001] This invention relates to the field of greenhouse technology, and in particular to an intelligent greenhouse external insulation blanket and control system. Background Technology

[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through and keeps the soil warm. It is used to cultivate plants and can provide a growing season and increase yields during seasons when plants are not suitable for growth. It is often used for the cultivation or seedling raising of warm-loving vegetables, flowers, trees and other plants during cold seasons.

[0003] Existing greenhouse external insulation blankets are usually a single piece sewn together. If one part of the insulation blanket is damaged, it cannot be replaced locally. In addition, the existing insulation blankets are laid by moving a winding roller along the outside of the greenhouse. Since the greenhouse is long and the insulation blanket is heavy, the winding roller has a large load-bearing capacity when moving along the edge of the greenhouse, which can easily cause the winding roller to break. The laying speed is also slow. Summary of the Invention

[0004] Based on the existing problems that greenhouse external insulation blankets are usually sewn together as a single piece, it is impossible to replace the damaged part. In addition, the existing insulation blankets are slow to lay because the greenhouse is long and the winding rollers have a large load-bearing capacity when moving along the edge of the greenhouse, which can easily lead to the winding rollers breaking.

[0005] The present invention proposes an intelligent greenhouse external insulation blanket, comprising insulation pads that are strip-shaped and evenly distributed in an arc-shaped array on the outer surface. Multiple insulation pads are joined together to form the insulation blanket body. Guide blocks are fixedly connected to the lower surfaces on both sides of the insulation blanket body. A docking device is provided on the opposite surfaces of every two adjacent insulation pads. A control groove in the shape of an arc is opened on the outer surface of the insulation blanket body, and a traction mechanism is provided on the inner wall of the control groove.

[0006] The docking device is used to connect every two adjacent insulation pads.

[0007] The traction mechanism is used to pull one end of the thermal insulation blanket body.

[0008] Preferably, the docking device includes mounting strips fixed to one side surface of two adjacent insulation pads, one side surface of the mounting strips is provided with a receiving groove, and the interiors of the two opposite receiving grooves are respectively movably hinged to a main hinge plate and an auxiliary hinge plate via a hinge shaft.

[0009] The above technical solution allows for the storage of the main hinge plate and the auxiliary hinge plate through a receiving slot.

[0010] Preferably, the free ends of the main hinge plate and the auxiliary hinge plate are movably hinged by a hinge shaft, and electromagnets are installed on the opposite surfaces of the two adjacent mounting strips.

[0011] The above technical solution enables the connection between two adjacent insulation pads through the hinge of the main joint plate and the auxiliary hinge plate.

[0012] Preferably, the traction mechanism includes a limiting shell fixed at the junction of the control groove and two adjacent insulation pads, the two limiting shells are symmetrically arranged, and the inner wall of the limiting shell is provided with a through opening.

[0013] The above technical solution enables the determination of the installation position of the limiting shell and the description of the distribution of the limiting shell.

[0014] Preferably, a connecting ball is provided between the two limiting shells, and multiple connecting balls are fixedly connected by steel cables. The outer surface of the steel cables is covered with a protective sleeve, and the outer surface of the steel cables is movably sleeved with the inner wall of the through-hole.

[0015] The above technical solution enables the connection of multiple steel cables using connecting balls, and the steel cables are protected by protective sleeves to prevent oxidation caused by exposure to air, which could affect their service life.

[0016] Preferably, a control system for an intelligent greenhouse external insulation blanket includes a greenhouse body, with mounting frames fixedly connected to both ends of the greenhouse body. The outer surface of the mounting frame is provided with a guide groove that slides and engages with the guide block. An auxiliary winding device and a main winding device are respectively provided on the inner walls of both ends of the mounting frame.

[0017] The auxiliary winding device is used to wind up the steel cable, thereby assisting in the laying of the thermal insulation blanket body.

[0018] The main winding device is used to wind up the main body of the thermal insulation blanket.

[0019] Preferably, the auxiliary winding device includes a first mounting base fixed to the inner wall of the mounting frame, a first servo motor is mounted on the inner wall of the first mounting base, and a first transmission wheel is fixedly sleeved on the main shaft surface of the first servo motor.

[0020] The above technical solution enables the first servo motor to be installed on the first mounting base and the first servo motor to drive the first transmission wheel.

[0021] Preferably, a support base is fixedly connected to one end surface of each of the two mounting frames, and an auxiliary winding roller for winding the steel cable is installed between the two support bases via a bearing. A second transmission wheel is fixedly sleeved on the outer surfaces of both ends of the auxiliary winding roller and is connected to the first transmission wheel via a belt.

[0022] The above technical solution enables the auxiliary take-up roller to be installed on the support base, and the rotational power of the first drive wheel to be transmitted to the second drive wheel via a belt.

[0023] Preferably, the main winding device includes a second mounting base fixed to the inner wall of the mounting frame, and a dual-axis motor is mounted on the inner wall of each of the two second mounting bases. A connecting shaft is fixedly connected between the main shafts of the two dual-axis motors facing each other. A third transmission wheel is fixedly sleeved on the outer surface of the other main shaft of the dual-axis motor. A telescopic frame is fixedly connected to one end surface of the mounting frame through a support column. A telescopic rod with an I-shaped structure is sleeved on the inner wall of the telescopic frame.

[0024] The above technical solution allows for the installation of a dual-axis motor via a second mounting base. Furthermore, the distance between the telescopic frame and the telescopic rod increases as the insulation blanket is rolled up more.

[0025] Preferably, a fourth transmission wheel is fixedly connected to one side surface of the telescopic rod and is connected to the third transmission wheel via a first belt; a small hydraulic cylinder is fixedly connected to the lower surface of the telescopic frame; a tensioning wheel for tensioning the first belt is fixedly connected to the end surface of the hydraulic rod of the small hydraulic cylinder away from the piston; a main winding roller is fixedly sleeved on the inner wall of the two fourth transmission wheels; and one end of the insulation blanket body is fixedly connected to the outer surface of the main winding roller.

[0026] The above technical solution allows for the control of the tension of the first belt using a small hydraulic cylinder, ensuring that the first belt remains taut and controlling the fourth drive wheel to rotate normally.

[0027] Preferably, a control method is provided: when the insulation blanket body is being rolled up, the electromagnet is de-energized, and the weight of the insulation blanket body itself causes the connection between every two adjacent insulation pads to be canceled, facilitating subsequent rolling. The first servo motor and the dual-axis motor are started synchronously. The first servo motor assists the rotation of the winding roller through the transmission control between the first and second transmission wheels, thereby loosening the steel cable. At the same time, the dual-axis motor controls the rotation of the main winding roller through the cooperation between the third and fourth transmission wheels, rolling up the insulation blanket body so that only the steel cable is at the top of the greenhouse structure, while the insulation blanket body is rolled up to one side of the greenhouse structure.

[0028] When laying the insulation blanket, the first servo motor and the dual-axis motor start synchronously. The first servo motor reverses and controls the rotation of the winding roller through the transmission between the first and second transmission wheels, thereby winding up the steel cable. At the same time, the dual-axis motor controls the rotation of the main winding roller through the cooperation between the third and fourth transmission wheels, loosening the insulation blanket and making the insulation blanket lay flat on the top of the greenhouse.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. By setting up a docking device and a traction mechanism, the two insulation pads can be connected through the hinge between the main hinge plate and the auxiliary hinge plate, and the main hinge plate and the auxiliary hinge plate can be stored in the receiving groove. The connection between the two insulation pads can be controlled by the energization or de-energization of the electromagnet.

[0031] 2. By setting up an auxiliary winding device, the steel cable can be wound or unwound by the drive control of the auxiliary winding roller by the first servo motor, thereby pulling one side of the insulation blanket body to prevent the insulation blanket body from slipping, and thus quickly completing the laying and winding of the insulation blanket body.

[0032] 3. By setting up a main winding device, the main winding roller can be controlled by two dual-axis motors to wind up and unwind the main body of the insulation blanket. The main winding roller only needs to rotate in place to complete the laying and winding of the main body of the insulation blanket, which reduces the load on the main winding roller caused by the weight of the insulation blanket and improves the efficiency of laying and winding the external insulation blanket of the greenhouse.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] Reference Figures 1-9 An intelligent greenhouse external insulation blanket includes insulation pads 1 that are strip-shaped and evenly distributed in an arc-shaped array on their outer surface. Multiple insulation pads 1 are joined together to form an insulation blanket body 2. In order to lay the insulation blanket body 2 flat, guide blocks 3 are fixedly connected to the lower surfaces on both sides of the insulation blanket body 2. A docking device is provided on the opposite surfaces of every two adjacent insulation pads 1. In order to facilitate the orderly rolling up of the insulation blanket body 2, an arc-shaped control groove 4 is provided on the outer surface of the insulation blanket body 2. A traction mechanism is provided on the inner wall of the control groove 4.

[0046] like Figures 1-3 and Figures 5-6As shown, the docking device is used to connect two adjacent insulation pads 1. The docking device includes a mounting strip 5 fixed to one side surface of two adjacent insulation pads 1. In order to install and store the main hinge plate 52 and the auxiliary hinge plate 53 after the two mounting strips 5 are attached, a receiving groove 51 is provided on one side surface of the mounting strip 5. The main hinge plate 52 and the auxiliary hinge plate 53 are respectively hinged to each other through a hinge shaft inside the two opposite receiving grooves 51. The main hinge plate 52 and the auxiliary hinge plate 53 can be stored through the receiving grooves 51. Furthermore, in order to connect the main hinge plate 52 and the auxiliary hinge plate 53, the free ends of the main hinge plate 52 and the auxiliary hinge plate 53 are hinged to each other through a hinge shaft. Electromagnets 54 are installed on the opposite surfaces of the two adjacent mounting strips 5. The connection between the two adjacent insulation pads 1 can be achieved through the hinge of the main mounting plate and the auxiliary hinge plate 53.

[0047] like Figures 1-3 , Figure 5 and Figure 7 As shown, the traction mechanism is used to pull one end of the insulation blanket body 2. The traction mechanism includes a limiting shell 6 fixed at the junction of the control groove 4 and two adjacent insulation pads 1. The two limiting shells 6 are symmetrically arranged. In order to facilitate the movement of the steel cable 63 in the limiting shell 6, a through hole 61 is provided on the inner wall of the limiting shell 6. The installation position of the limiting shell 6 can be determined and the distribution of the limiting shell 6 can be described. In order to enable the steel cable 63 to move a small distance in the limiting shell 6, a connecting ball 62 is provided between the two limiting shells 6, and multiple connecting balls 62 are connected by the steel cable 63. In order to protect the steel cable 63, a protective sleeve 64 is wrapped around the outer surface of the steel cable 63. The protective sleeve 64 protects the steel cable 63, so that the outer surface of the steel cable 63 is movably sleeved with the inner wall of the through hole 61. Multiple sections of the steel cable 63 can be connected by the connecting ball 62 to prevent the steel cable 63 from being exposed to the air and oxidizing, which would affect its service life.

[0048] By setting up a docking device and a traction mechanism, the two insulation pads 1 can be connected through the hinge between the main hinge plate 52 and the auxiliary hinge plate, and the main hinge plate 52 and the auxiliary hinge plate can be stored in the receiving groove 51. The connection between the two insulation pads 1 can be controlled by the energization or de-energization of the electromagnet 54.

[0049] like Figures 1-5 and Figures 7-9As shown, a control system for an intelligent greenhouse external insulation blanket includes a greenhouse body 7. The roof of the greenhouse body 7 is elliptical or continuously wavy. In order to install the auxiliary winding device and the main winding device, mounting frames 8 are fixedly connected to both ends of the surface of the greenhouse body 7. Furthermore, in order to guide the insulation blanket body 2, a guide groove 9 is provided on the outer surface of the mounting frame 8 to slide and engage with the guide block 3. The inner walls of both ends of the mounting frame 8 are respectively provided with the auxiliary winding device and the main winding device.

[0050] like Figures 1-5 and Figures 7-8 As shown, the auxiliary winding device is used to wind up the steel cable 63, thereby assisting in the laying of the insulation blanket body 2. The auxiliary winding device includes a first mounting base 10 fixed to the inner wall of the mounting frame 8. In order to drive the auxiliary winding roller 104, a first servo motor 101 is mounted on the inner wall of the first mounting base 10. In order to drive the first transmission wheel 102, the first transmission wheel 102 is fixedly sleeved on the spindle surface of the first servo motor 101. The first servo motor 101 can be mounted through the first mounting base 10, and the first servo motor 101 drives the first transmission wheel 102. The take-up roller 104 is installed, and a support base 103 is fixedly connected to one end surface of each of the two mounting frames 8. An auxiliary take-up roller 104 for winding the steel cable 63 is installed between the two support bases 103 via a bearing. In order to transmit the rotational force of the first drive wheel 102 to the second drive wheel 105, a second drive wheel 105 is fixedly sleeved on the outer surface of both ends of the auxiliary take-up roller 104 and is connected to the first drive wheel 102 via a belt. The auxiliary take-up roller 104 can be installed through the support base 103, and the rotational force of the first drive wheel 102 can be transmitted to the second drive wheel 105 via the belt.

[0051] By setting up an auxiliary winding device, the first servo motor 101 can drive the auxiliary winding roller 104 to control the steel cable 63 to wind or unwind, thereby pulling one side of the insulation blanket body 2 to prevent the insulation blanket body 2 from slipping, and thus quickly completing the laying and winding of the insulation blanket body 2.

[0052] like Figures 1-5 and Figure 9As shown, the main winding device is used to wind up the insulation blanket body 2. The main winding device includes a second mounting base 11 fixed to the inner wall of the mounting frame 8. In order to install the dual-axis motor 1110 at both ends of the greenhouse, a dual-axis motor 1110 is installed on the inner wall of both second mounting bases 11. Furthermore, in order to make the dual-axis motor 1110 run synchronously, a connecting shaft 1101 is fixedly connected between the opposing main shafts of the two dual-axis motor 1110. Furthermore, in order to install the third transmission wheel 1102, a third transmission wheel is fixedly sleeved on the outer surface of the other main shaft of the dual-axis motor 1110. The drive wheel 1102 is designed to control the distance between the telescopic frame 1103 and the telescopic rod 1104 as the main winding roller 1106 winds up the insulation blanket body 2. The telescopic frame 1103 is fixedly connected to one end surface of the mounting frame 8 by a support column, and the telescopic rod 1104 with an I-shaped structure is sleeved on the inner wall of the telescopic frame 1103. The dual-axis motor 1110 can be installed through the second mounting seat 11. Through the cooperation of the telescopic frame 1103 and the telescopic rod 1104, the distance between the telescopic frame 1103 and the telescopic rod 1104 increases as the insulation blanket body 2 is wound up more.

[0053] To install the fourth drive wheel 1107, a fourth drive wheel 1107 is fixedly connected to one side surface of the telescopic rod 1104 and is connected to the third drive wheel 1102 via the first belt 1105. To keep the first belt 1105 taut at all times, a small hydraulic cylinder 1108 is fixedly connected to the lower surface of the telescopic frame 1103, and a tensioning wheel 1109 for tensioning the first belt 1105 is fixedly connected to the end surface of the hydraulic rod of the small hydraulic cylinder 1108 away from the piston. Furthermore, to install the main take-up roller 1106, the main take-up roller 1106 is fixedly sleeved on the inner wall of the two fourth drive wheels 1107, so that one end of the insulation blanket body 2 is fixedly connected to the outer surface of the main take-up roller 1106. The tension of the first belt 1105 can be controlled by the small hydraulic cylinder 1108, so that the first belt 1105 is always taut and the fourth drive wheel 1107 is controlled to rotate normally.

[0054] By setting up a main winding device, the main winding roller 1106 can be controlled by two dual-axis motors 1110 to wind up and unwind the insulation blanket body 2. The main winding roller 1106 only needs to rotate in place to complete the laying and winding of the insulation blanket body 2, which reduces the load on the main winding roller 1106 caused by the weight of the insulation blanket body 2, and improves the efficiency of laying and winding the outer insulation blanket of the greenhouse.

[0055] Working principle: When the insulation blanket body 2 is rolled up, the control electromagnet 54 is de-energized. Due to the weight of the insulation blanket body 2 itself, the connection between every two adjacent insulation pads 1 is canceled, which facilitates subsequent rolling. The control first servo motor 101 and dual-axis motor 1110 are started synchronously. The first servo motor 101 controls the rotation of the auxiliary winding roller 104 through the transmission between the first transmission wheel 102 and the second transmission wheel 105, thereby loosening the steel cable 63. At the same time, the dual-axis motor 1110 controls the rotation of the main winding roller 1106 through the cooperation between the third transmission wheel 1102 and the fourth transmission wheel 1107, which rolls up the insulation blanket body 2, so that only the steel cable 63 is at the top of the greenhouse body 7, while the insulation blanket body 2 is rolled up to one side of the greenhouse body 7.

[0056] When laying the insulation blanket body 2, the first servo motor 101 and the dual-axis motor 1110 start synchronously. The first servo motor 101 reverses and controls the rotation of the auxiliary winding roller 104 through the transmission between the first transmission wheel 102 and the second transmission wheel 105, thereby winding up the steel cable 63. At the same time, the dual-axis motor 1110 controls the rotation of the main winding roller 1106 through the cooperation between the third transmission wheel 1102 and the fourth transmission wheel 1107, loosening the insulation blanket body 2 so that the insulation blanket body 2 is laid flat on the top of the greenhouse 7.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
