Description

Technical Field

[0001] This invention relates to the field of agricultural greenhouse technology, and in particular to a pressing device and pressing control method for thermal insulation blankets used in solar greenhouses. Background Technology

[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through while maintaining warmth, used for cultivating plants. During seasons unsuitable for plant growth, it provides a growing period and increases yield, and is primarily used for cultivating or raising seedlings of warm-season vegetables, flowers, and trees. In recent years, greenhouse cultivation has gained increasing attention, especially in northern my country, where the area of ​​greenhouses has been increasing year by year. However, the large temperature difference between day and night in northern my country during winter and spring necessitates nighttime insulation measures for greenhouses to ensure crop survival and increase yield. This is typically achieved by laying insulating blankets over the greenhouse structure.

[0003] Thermal insulation blankets need to be frequently laid out depending on the climate. For example, during the day when there is plenty of sunshine and the temperature is relatively high, the blankets are usually rolled up to allow the crops inside the greenhouse to receive sufficient sunlight. At night, when the temperature drops, the blankets are usually laid down to maintain the temperature inside the greenhouse and provide a suitable growing temperature for the crops. However, in practical applications, when the blankets are laid down, environmental factors such as strong winds can cause them to billow or shift from their original position, leaving some areas of the greenhouse surface uncovered. This reduces the insulation effect inside the greenhouse, compromises the growing conditions for the crops, and can even cause damage and death to the crops in harsh environments. Summary of the Invention

[0004] In view of this, and to address the above shortcomings, it is necessary to propose a pressing device and pressing control method for thermal insulation blankets used in solar greenhouses, so as to press the thermal insulation blankets tightly onto the surface of the greenhouse, ensure the covering effect of the thermal insulation blankets, and thus ensure the growth conditions of crops.

[0005] In a first aspect, the present invention provides a heat-insulating blanket clamping device for a solar greenhouse, comprising: a locking mechanism, a tightening rope mechanism, and a control mechanism;

[0006] The locking mechanism includes two parts, respectively located at both ends of the front of the greenhouse. These two locking mechanisms are used to lock and fix both ends of the insulation blanket roll when it moves to the bottom of the front of the greenhouse. The rope tightening mechanism includes at least two parts, each of which includes: a fixed base, a fastening rope, a rope winding component, and a first drive motor. The fixed base is fixed to the back of the greenhouse, and the rope winding component is fixed to the bottom end of the fixed base. One end of the fastening rope is fixed to the insulation blanket roll, and the other end is fixed to the rope winding component. The drive end of the first drive motor is rotatably connected to the rope winding component.

[0007] The control mechanism is electrically connected to the locking mechanism and the tightening mechanism respectively, and is used to control the insulation blanket roll to perform the rolling or unrolling operation; and when the insulation blanket roll moves to the bottom of the front of the greenhouse, the locking mechanism is controlled to lock and fix the two ends of the insulation blanket roll, and after the locking mechanism is locked and fixed, the first drive motor of the tightening mechanism is controlled to work, so that the first drive motor drives the winding component to rotate and wind the tightening rope, so that the tightening rope presses the insulation blanket tightly.

[0008] Preferably, the rope tightening mechanism further includes a pulley, which is disposed at the upper end of the fixed base, and the tightening rope is laid on the pulley. The position of the pulley is such that the tightening rope does not contact the wall of the greenhouse. The position includes the height of the pulley from the ground and the distance between the pulley and the back wall of the greenhouse.

[0009] Preferably, each of the tensioning mechanisms is distributed on the back of the greenhouse, and at least one tensioning mechanism is provided at each end of the back of the greenhouse.

[0010] Preferably, the fastening rope passes through the interlayer of the thermal insulation blanket and is then fixed to the roll of the thermal insulation blanket.

[0011] Preferably, each locking mechanism includes a fixed base plate, a first baffle, a second baffle, a U-shaped groove-like fixing member, a locking rod, a transmission rod, a gear, and a second drive motor electrically connected to the control mechanism; the lower surface of the fixed base plate is horizontally fixed to the ground, and the first and second baffles are respectively vertically fixed to the upper surface of the fixed base plate on the side near the greenhouse, with the distance between the first and second baffles greater than the diameter of the insulation blanket roll; the fixing member is fixed to the upper surface of the fixed base plate on the side away from the greenhouse, with the U-shaped groove opening downwards, and a gear is provided inside the U-shaped groove of the fixing member for fixing... The second drive motor is fixedly installed on the outside of the component. The drive end of the second drive motor passes through the fixed component and is connected to the internal gear transmission. The lower surface of the transmission rod is provided with teeth. The transmission rod is connected to the gear through the teeth. One end of the transmission rod is fixedly connected to the locking rod. The upper ends of the first baffle and the second baffle are both provided with locking holes. When the gear drives the transmission rod to move, the transmission rod can drive the locking rod to pass through the locking holes on the first baffle and the second baffle in sequence, so as to lock and fix the heat insulation roll in the closed area formed by the fixed base plate, the first baffle, the second baffle and the locking rod.

[0012] Preferably, each locking mechanism further includes a pressure monitoring component electrically connected to the control mechanism. The pressure monitoring component is fixedly disposed on the side of the fixed base plate, and pressure is applied to the pressure monitoring component when the insulation blanket roll is lowered to the bottom. The pressure monitoring component is used to upload the monitored pressure value to the control mechanism. The control mechanism is used to control the second drive motor to work when the uploaded pressure value reaches a preset pressure threshold, so as to lock the insulation blanket roll.

[0013] Preferably, an angle sensor is provided at the connection point of the two support arms of the rolling shutter mechanism used to perform the rolling shutter operation. The angle sensor is electrically connected to the control mechanism to monitor the angle information between the two support arms and upload the monitored angle information to the control mechanism. The control mechanism is used to control the second drive motor to work when the uploaded angle information reaches a preset angle threshold, so as to lock the insulation blanket roll. The angle threshold indicates an angle value that allows the insulation blanket roll to be located within the closed area formed by the fixed base plate, the first baffle, the second baffle, and the locking rod.

[0014] Preferably, the device further includes a wind speed measuring component electrically connected to the control mechanism. The wind speed measuring component is fixedly installed on the top of the greenhouse and is used to measure the wind speed in the area where the greenhouse is located, and send the measured wind speed information to the control mechanism. The control mechanism is used to adjust the tightness of the fastening rope according to the received wind speed information.

[0015] Secondly, the present invention also provides a compression control method, wherein the main body of the method is the compression device for the heat insulation blanket of the solar greenhouse as described in the first aspect, and the method includes the following steps:

[0016] Step 101: The control mechanism of the insulation blanket clamping device for the solar greenhouse generates a locking command;

[0017] Step 102: After generating the locking command, the control mechanism controls the locking mechanism to lock and fix the two ends of the insulation blanket roll.

[0018] Step 103: After the two ends of the insulation blanket roll are locked and fixed, the control mechanism controls the tightening mechanism to tighten the fastening rope of the tightening mechanism to compress the insulation blanket.

[0019] Step 104: The control mechanism receives the wind speed information of the area where the greenhouse is located in real time from the wind speed measurement component, and adjusts the tightness of the fastening rope according to the received wind speed information.

[0020] Preferably, step 101 specifically includes:

[0021] The control mechanism receives the pressure value uploaded by the pressure monitoring component in real time, and generates a locking command when the pressure value reaches the preset pressure threshold.

[0022] And / or,

[0023] The control mechanism receives angle information uploaded by the angle sensor in real time, and generates a locking command when the uploaded angle information reaches a preset angle threshold.

[0024] As can be seen from the above technical solution, the pressing device and pressing control method for the thermal insulation blanket in the solar greenhouse provided in the embodiments of the present invention include a locking mechanism, a tightening rope mechanism and a control mechanism. The locking mechanism is respectively set at both ends of the thermal insulation blanket roll, and is used to lock and fix the thermal insulation blanket roll when it descends to the bottom of the greenhouse during the curtain release operation, so as to prevent the thermal insulation blanket roll from deviating from its original position due to environmental factors such as wind force, which would cause the covering effect of the thermal insulation blanket to deteriorate. The tightening mechanism includes a tightening rope, a tightening component, and a first drive motor. One end of the tightening rope is fixed to the winding component, and the other end is wound around the winding component located at the back of the greenhouse. When the locking mechanism locks the insulation blanket roll in place, the first drive motor drives the winding component to rotate, winding the tightening rope and tightening it firmly against the insulation blanket. This prevents the insulation blanket from being blown around by the wind, causing it to billow or sway, or drift away from its proper position, which would reduce its covering effect on the greenhouse film and affect crop growth. Therefore, this solution can firmly press the insulation blanket onto the greenhouse film, ensuring the effective covering of the greenhouse film and thus guaranteeing the growing conditions for crops inside the greenhouse.

Detailed Implementation

[0031] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0032] See Figure 1-5 The present invention provides a heat insulation blanket compression device for a solar greenhouse, comprising: a locking mechanism 10, a rope tightening mechanism 20 and a control mechanism 30;

[0033] The locking mechanism 10 includes two parts, which are respectively set at both ends of the front of the greenhouse. The two locking mechanisms 10 are used to lock and fix the two ends of the insulation blanket roll 40 when the insulation blanket roll 40 moves to the bottom of the front of the greenhouse. The rope tightening mechanism 20 includes at least two parts. Each rope tightening mechanism 20 includes: a fixed base 21, a fastening rope 22, a rope winding component 23 and a first drive motor 24. The fixed base 21 is fixed to the back of the greenhouse. The bottom end of the fixed base 21 is fixed with the rope winding component 23. One end of the fastening rope 22 is fixed to the insulation blanket roll 40 and the other end is fixed to the rope winding component 23. The drive end of the first drive motor 24 is rotatably connected to the rope winding component 23.

[0034] The control mechanism 30 is electrically connected to the locking mechanism 10 and the rope tightening mechanism 20 respectively, and is used to control the insulation blanket roll 40 to perform the rolling or unrolling operation; and when the insulation blanket roll 40 moves to the bottom of the front of the greenhouse, the control locking mechanism 10 locks and fixes the two ends of the insulation blanket roll 40, and after the locking mechanism 10 locks and fixes, the control first drive motor 24 of the rope tightening mechanism 20 is operated so that the first drive motor 24 drives the rope winding component 23 to rotate and wind the fastening rope 22, so that the fastening rope 22 presses the insulation blanket tightly.

[0035] The locking mechanism 10 should include two parts, which are respectively installed at both ends of the front of the greenhouse. This example uses a single insulation blanket roll 40 to perform the rolling and unrolling operation of a single greenhouse, so installing the locking mechanism 10 at each end of the greenhouse is sufficient. However, if a greenhouse has multiple insulation blanket rolls 40 for rolling and unrolling operations, a locking mechanism 10 should be installed at both ends of each insulation blanket roll 40 to achieve locking and fixing at both ends of each insulation blanket roll 40.

[0036] Specifically, each locking mechanism 10 may include a fixed base plate 11, a first baffle 12, a second baffle 13, a U-shaped groove-like fixing member 14, a locking rod 15, a transmission rod 16, a gear 17, and a second drive motor 18 electrically connected to the control mechanism 30; the lower surface of the fixed base plate 11 is horizontally fixed to the ground, the first baffle 12 and the second baffle 13 are respectively vertically fixed to the upper surface of the fixed base plate 11 on the side close to the greenhouse, and the distance between the first baffle 12 and the second baffle 13 is greater than the diameter of the insulation blanket roll 40; the fixing member 14 is fixed to the upper surface of the fixed base plate 11 on the side away from the greenhouse, and the opening of the U-shaped groove faces downward, and the gear 17 is provided inside the U-shaped groove of the fixing member 14. A second drive motor 18 is fixedly installed on the outside of the fixing member 14. The drive end of the second drive motor 18 passes through the fixing member 14 and is connected to the gear 17 inside. The lower surface of the transmission rod 16 is provided with teeth. The transmission rod 16 is connected to the gear 17 through the teeth. One end of the transmission rod 16 is fixedly connected to the locking rod 15. The upper ends of the first baffle 12 and the second baffle 13 are both provided with locking holes. When the gear 17 drives the transmission rod 16 to move, the transmission rod 16 can drive the locking rod 15 to pass through the locking holes on the first baffle 12 and the second baffle 13 in sequence, so as to lock and fix the heat insulation roll 40 in the closed area formed by the fixed base plate 11, the first baffle 12, the second baffle 13 and the locking rod 15.

[0037] In this embodiment, the fixed base plate 11, the first baffle 12, and the second baffle 13 form a flat "F"-shaped structure. The first baffle 12 and the second baffle 13 form the two horizontal sides of the "F"-shaped structure. When the insulation blanket roll 40 moves to the bottom, it can be located between the first baffle 12 and the second baffle 13. The upper ends of the first baffle 12 and the second baffle 13 are provided with locking holes. The locking rod 15 can pass through the locking holes of the second baffle 13 and the first baffle 12 in sequence to lock and fix the insulation blanket roll 40 in the closed area formed by the fixed base plate 11, the first baffle 12, the second baffle 13, and the locking rod 15. In this way, even if the insulation blanket is blown by a strong wind, it cannot swing up and down because the insulation blanket roll 40 is locked and fixed, thereby avoiding the insulation blanket being blown away from the required covering position and affecting the greenhouse film covering effect.

[0038] Furthermore, to drive the locking rod 15, a U-shaped groove structure fixing member 14 is provided on the fixed base plate 11. A gear 17 is installed inside the fixing member 14. A second drive motor 18, fixed to the outside of the fixing member 14, can drive the gear 17 to rotate. The upper end of the gear 17 meshes with the teeth of the lower end of the transmission rod 16, while the other end of the transmission rod 16 is fixedly connected to one end of the locking rod 15. Thus, when the second drive motor 18 drives the gear 17 to rotate counterclockwise, the transmission rod 16 moves towards the greenhouse, causing the free end of the locking rod 15 to pass sequentially through the locking holes of the second baffle 13 and the first baffle 12, thereby locking and fixing the insulation blanket roll 40. When the second drive motor 18 drives the gear 17 to rotate clockwise in reverse, the transmission rod 16 moves away from the greenhouse, causing the free end of the locking rod 15 to extend sequentially from the locking holes of the first baffle 12 and the second baffle 13, thereby releasing the locking and fixing of the insulation blanket roll 40.

[0039] To trigger the locking mechanism 10 to perform the locking and fixing operation on the insulation blanket roll 40, the following three implementation methods can be considered:

[0040] Implementation method 1: The control mechanism 30 controls the roller blind mechanism 50 to perform the curtain lowering operation. When the roller blind mechanism 50 stops working, it can generally be assumed that the thermal insulation blanket roller 40 has been lowered into place. At this time, the control mechanism 30 controls the second drive motor 18 to work, that is, controls the locking mechanism 10 to perform the locking and fixing operation to lock and fix the thermal insulation blanket roller 40.

[0041] This implementation method is applicable to situations where only a complete roll-up and unrolling operation is performed, meaning that when unrolling the insulation blanket, the roll 40 will inevitably be lowered to its lowest point. No additional equipment or components are required, and the control is simpler.

[0042] However, in some embodiments, the insulation blanket roll 40 does not always need to be fully released. Often, a certain amount is rolled up or down depending on climatic factors, such as the insulation blanket needing to be rolled to the middle position based on temperature and light intensity. In this case, when performing the rolling-up and unrolling operation, if the control method of Embodiment 1 is followed, the locking mechanism 10 will also engage after the insulation blanket roll 40 stops descending to halfway down the greenhouse structure. However, there is no need to engage the locking mechanism at this point. Therefore, this solution considers using Embodiments 2 and 3 to address this situation.

[0043] Implementation Method 2: In this embodiment, a pressure monitoring component 19 is considered to trigger the locking mechanism 10 by pressure. Specifically, each locking mechanism 10 also includes a pressure monitoring component 19 electrically connected to the control mechanism 30. The pressure monitoring component 19 is fixedly installed on the side of the fixed base plate 11, and pressure is applied to the pressure monitoring component 19 when the insulation blanket roll 40 is lowered to the bottom. The pressure monitoring component 19 is used to upload the monitored pressure value to the control mechanism 30. When the uploaded pressure value reaches a preset pressure threshold, the control mechanism 30 controls the second drive motor 18 to work to lock the insulation blanket roll 40.

[0044] In this embodiment, a pressure monitoring component 19 is installed on the side of the fixed base plate 11. When the insulation blanket roll 40 reaches the bottom during the curtain unloading operation, it presses against the pressure monitoring component 19. The pressure monitoring component 19 transmits the monitored pressure to the control mechanism 30. The control mechanism 30 determines that if the current pressure value reaches a preset pressure threshold, it means that the insulation blanket roll 40 has reached the bottom and can be locked in place. That is, the control mechanism 30 controls the second drive motor 18 of the locking mechanism 10 to lock and fix the insulation blanket roll 40. Moreover, by setting a pressure threshold, this solution can prevent the locking mechanism 10 from malfunctioning due to pressure from debris, snow, or other substances on the pressure monitoring component 19.

[0045] Implementation Method 3: In this embodiment, the angle between the two support arms 51 / 52 performing the rolling shutter operation is monitored to determine whether the insulation blanket roll 40 has been lowered into place, and the locking mechanism 10 is triggered accordingly. Specifically, an angle sensor 60 is provided at the connection between the two support arms 51 / 52 of the rolling shutter mechanism 50 performing the rolling shutter operation. The angle sensor 60 is electrically connected to the control mechanism 30 and is used to monitor the angle information between the two support arms 51 / 52 and upload the monitored angle information to the control mechanism 30. When the uploaded angle information reaches a preset angle threshold, the control mechanism 30 controls the second drive motor 18 to work to lock the insulation blanket roll 40. The angle threshold indicates an angle value that allows the insulation blanket roll 40 to be located within the closed area formed by the fixed base plate 11, the first baffle 12, the second baffle 13, and the locking rod 15.

[0046] In this embodiment, an angle sensor 60 is installed at the connection point of the two support arms 51 / 52 performing the rolling and unrolling operation. This sensor monitors the angle information between the two support arms 51 / 52 in real time and uploads the monitored angle information to the control mechanism 30. When the insulation blanket roll 40 is in position, it corresponds to a fixed angle range. By setting an appropriate angle threshold, the control mechanism 30 can determine whether the insulation blanket roll 40 has been lowered into position. When the monitored angle information reaches the preset angle threshold, it indicates that the insulation blanket roll 40 has been lowered into position. The control mechanism 30 can then control the second drive motor 18 of the locking mechanism 10 to work, thereby locking and fixing the insulation blanket roll 40.

[0047] The tightening mechanism 20 mainly includes a fixed base 21, a tightening rope 22, a rope winding component 23, and a first drive motor 24. The fixed base 21 is fixed to the wall behind the greenhouse. The rope winding component 23 is fixed to the bottom of the fixed base 21 and is driven by the first drive motor 24, which can drive the rope winding component 23 to rotate. The tightening rope 22 can be a steel wire rope, with one end wound around the rope winding component 23 and the other end passing through the insulation blanket's interlayer and fixed to the insulation blanket's roller 40. Thus, when it is necessary to tighten the insulation blanket, the control mechanism 30 controls the first drive motor 24 to work, driving the rope winding component 23 to rotate. The rotation of the rope winding component 23 can automatically wind the tightening rope 22, thereby tightening the rope 22 at the insulation blanket and preventing the insulation blanket from being blown up by the wind. When performing the rolling shutter operation, the fastening rope 22 is loosened by the tightening mechanism 20, and the fastening rope 22 is rolled into the insulation blanket when the shutter is rolled up, which will not affect the rolling shutter operation. Moreover, the fastening rope 22 is located in the interlayer of the insulation blanket, so the position of the fastening rope 22 is relatively fixed and will not deviate from the position to be tightened, and the fastening rope 22 will not be tangled or messed up during the rolling shutter operation.

[0048] The rope tightening mechanism 20 may further include a pulley 25, which is disposed on the upper end of the fixed base 21. The tightening rope 22 is draped over the pulley 25, and the pulley 25 is positioned such that the tightening rope 22 does not contact the greenhouse wall. The position includes the height of the pulley 25 from the ground and the distance between the pulley 25 and the back wall of the greenhouse. This ensures that the tightening rope 22 does not contact the greenhouse wall when turning from the front to the back of the greenhouse, thus minimizing friction between the rope 22 and the greenhouse wall during tightening operations, making the tightening process easier. Furthermore, the presence of the pulley 25 prevents wear and tear between the rope 22 and the greenhouse wall.

[0049] Multiple tensioning mechanisms 20 can be installed, distributed along the back of the greenhouse, with at least one tensioning mechanism 20 at each end of the back of the greenhouse. Since wind most easily inflates the insulation blanket from both ends, installing tensioning mechanisms 20 at at least both ends prevents wind from blowing the insulation blanket up from the sides. It is easy to understand that if multiple insulation blanket rolls 40 are installed on a greenhouse for rolling up and down the curtain, then each insulation blanket roll 40 should have a tensioning mechanism 20 at both ends.

[0050] In some embodiments, persistent strong winds may cause the tightened securing rope 22 to loosen, therefore, adjusting the tightness of the securing rope 22 according to the wind speed is considered. A specific greenhouse insulation blanket tightening device may also include a wind speed measuring component 70 electrically connected to a control mechanism 30. This wind speed measuring component 70 is fixedly installed on the top of the greenhouse and is used to measure the wind speed in the area where the greenhouse is located, and send the measured wind speed information to the control mechanism 30; the control mechanism 30 is used to adjust the tightness of the securing rope 22 according to the received wind speed information.

[0051] In this embodiment, by monitoring the wind speed in the area where the greenhouse is located in real time and adjusting the tightness of the fastening rope 22 according to the wind speed, it is possible not only to ensure that the fastening rope 22 can keep the insulation blanket tight when the wind is strong, but also to reduce the amount of winding of the fastening rope 22 when there is no wind or the wind is weak, thereby reducing the work of the first drive motor 24 and saving energy.

[0052] Furthermore, the present invention also provides a compression control method, wherein the main body of the method is the compression device for the heat insulation blanket of the solar greenhouse as described in the above embodiments, and the method includes the following steps:

[0053] Step 101: The control mechanism 30 of the greenhouse insulation blanket clamping device generates a locking command;

[0054] Step 102: After generating the locking command, the control mechanism 30 controls the locking mechanism 10 to lock and fix the two ends of the insulation blanket roll 40.

[0055] Step 103: After the two ends of the insulation blanket roll 40 are locked and fixed, the control mechanism 30 controls the rope tightening mechanism 20 to tighten the rope 22 of the rope tightening mechanism 20 to compress the insulation blanket.

[0056] Step 104: The control mechanism 30 receives the wind speed information of the area where the greenhouse is located in real time collected by the wind speed measurement component 70, and adjusts the tightness of the fastening rope 22 according to the received wind speed information.

[0057] In one embodiment, when the control mechanism 30 of the greenhouse insulation blanket clamping device generates a locking command in step 101, the control mechanism 30 can receive the pressure value uploaded by the pressure monitoring component 19 in real time, and generate a locking command when the pressure value reaches a preset pressure threshold.

[0058] In another embodiment, when the control mechanism 30 of the greenhouse insulation blanket clamping device generates a locking command in step 101, the control mechanism 30 can also receive angle information uploaded by the angle sensor 60 in real time, and generate a locking command when the uploaded angle information reaches a preset angle threshold.

The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that implementing all or part of the processes of the above embodiments and making equivalent changes according to the claims of this invention still fall within the scope of the invention.
