Description

Technical Field

[0001] The utility model relates to the technical field of agricultural greenhouses, in particular to a heat preservation quilt reel locking device for a solar greenhouse. Background Art

[0002] A greenhouse, also known as a warm house, is a facility that allows light to pass through and keeps warm for growing plants. In seasons that are not suitable for plant growth, it can provide a growth period and increase yields. It is mostly used for the cultivation or raising of seedlings of warm-loving vegetables, flowers, trees and other plants in low-temperature seasons. In recent years, greenhouse cultivation has been increasingly valued by the government and farmers, especially in northern my country, where the area of ​​greenhouses has increased year by year. However, the temperature difference between day and night in winter and spring in northern my country is large. In order to ensure the survival of crops and increase yields, it is necessary to take insulation measures for the greenhouse at night, generally by laying insulation blankets on the greenhouse.

[0003] The insulation blanket needs to be laid frequently according to the climate environment. For example, during the day when the sun is full and the temperature is relatively high, the insulation blanket is usually rolled up so that the crops in the greenhouse can receive enough sunlight. At night when the temperature drops, the insulation blanket is usually laid down on the greenhouse to ensure the temperature in the greenhouse and provide a suitable growth temperature for the crops in the greenhouse. However, when the insulation blanket is laid down on the greenhouse, strong winds will cause the insulation blanket reel moving to the bottom to swing violently, which will not only affect the insulation blanket covering effect of the greenhouse, but also cause the insulation effect of the greenhouse to be unable to be guaranteed, affecting the growth of crops. In addition, due to the violent swing of the insulation blanket reel, the greenhouse film is easily damaged, resulting in large economic losses. Utility Model Content

When the driving motor 17 drives the gear 16 to rotate, it can drive the other end of the locking rod 15 to pass through the locking holes 18 on the second baffle 13 and the first baffle 12 in turn, so as to lock and fix the thermal insulation quilt reel 30 in the closed area formed by the fixed base 11, the first baffle 12, the second baffle 13 and the locking rod 15; the control mechanism 20 is electrically connected to the driving motor 17, and is used to control the rotation of the driving motor 17, so that the locking mechanism 10 performs the locking and fixing operation of the thermal insulation quilt reel 30.

[0019] The locking device of the heat preservation quilt reel 30 for the solar greenhouse provided in this embodiment is mainly composed of a locking mechanism 10 and a control mechanism 20, wherein the locking mechanism 10 mainly includes a fixed base 11, a first baffle 12, a second baffle 13, a fixing member 14, a locking rod 15, a gear 16 and a driving motor 17, the fixed base 11, the first baffle 12 and the second baffle 13 constitute a U-shaped structure with an opening upward, and the upper end opening of the U-shaped structure is used for the heat preservation quilt reel 30 to enter, that is, when the heat preservation quilt reel 30 completes the curtain release operation, it moves to the lower end of the front of the greenhouse to complete the curtain release operation, and at this time the heat preservation quilt reel 30 can just be located by the fixed base 11, The first baffle plate 12 and the second baffle plate 13 are formed inside the U-shaped structure, and the upper ends of the first baffle plate 12 and the second baffle plate 13 are both provided with locking holes 18, and the locking holes 18 are provided with locking rods 15 that can be extended and extended. In this way, under normal circumstances, the locking rod 15 is in an extended state. When the thermal insulation quilt reel 30 performs the curtain lowering operation and enters the U-shaped structure, the locking rod 15 extends, that is, passes through the locking holes 18 at the upper ends of the second baffle plate 13 and the first baffle plate 12 in turn, so that the thermal insulation quilt reel 30 is locked and fixed in the closed area formed by the fixed base 11, the first baffle plate 12, the second baffle plate 13 and the locking rod 15, thereby realizing the locking and fixation of the thermal insulation quilt reel 30.

[0020] As for the driving of the locking rod 15, a tooth pattern is provided on the lower surface of one end thereof away from the first baffle plate 12 and the second baffle plate 13, which is meshed with a gear 16 fixed on the fixing member 14, and the gear 16 is driven by a driving motor 17 fixed on the outside of the fixing member 14. In this way, when the locking operation is performed, the driving motor 17 drives the gear 16 to rotate, and the rotation of the gear 16 can drive the locking rod 15 to move in the horizontal direction, thereby realizing the insertion and extension of the locking rod 15 from the locking hole 18. Specifically, in practice, the forward and reverse rotation of the gear 16 can be realized by the forward and reverse rotation of the driving motor 17, thereby realizing the movement of the locking rod 15 in the insertion direction and the extension direction.

[0021] Among them, the fixing part 14 is a U-shaped groove structure, and when the fixing part 14 is fixed, it is fixed on the fixed base 11 with the U-shaped groove opening facing downward. The gear 16 is arranged inside the U-shaped groove structure, and the drive motor 17 is arranged on the outside, and its driving end passes through the fixing part 14 of the U-shaped groove structure and is driven and connected with the internal gear 16, so that the gear 16 can be driven to rotate by the rotation of the drive motor 17.

[0022] In order to trigger the locking mechanism 10 to perform the locking and fixing operation on the heat-insulating rolled shaft 30, the following three implementation methods can be considered:

[0023] Embodiment 1: The control mechanism 20 controls the rolling curtain mechanism 40 to perform the curtain lowering operation. When the rolling curtain mechanism 40 stops working, it can generally be considered that the thermal insulation quilt reel 30 has been lowered into place. The control mechanism 20 then controls the drive motor 17 to work, that is, controls the locking mechanism 10 to perform the locking and fixing operation to lock and fix the thermal insulation quilt reel 30.

[0024] This embodiment is suitable for the situation where only a complete rolling and unwinding operation is performed, that is, when performing the curtain unwinding operation, the insulation quilt reel 30 will inevitably be lowered to the bottom, no additional equipment or devices are required, and the control is also simpler.

[0025] However, in some embodiments, the insulation quilt reel 30 sometimes does not need to be fully released to the bottom, and often needs to be rolled up a certain amount according to climate and environmental factors, such as the insulation quilt needs to be rolled up to the middle position according to temperature and light intensity. At this time, when performing the curtain rolling operation, if the control method of embodiment 1 is used, when the insulation quilt reel 30 drops to the position of half of the greenhouse and stops working, the locking mechanism 10 also performs the locking operation, but there is no need to perform the locking operation at this time. Therefore, for this situation, this solution considers using the following embodiment 2 or embodiment 3 to achieve it.

[0026] Embodiment 2: In this embodiment, it is considered to set a pressure monitoring component 19 to trigger the action of the locking mechanism 10 by pressure. Specifically, the locking mechanism 10 also includes a pressure monitoring component 19, which is electrically connected to the control mechanism 20, fixedly arranged on the side of the fixed base 11, and can apply pressure to the pressure monitoring component 19 when the insulation reel 30 is lowered to the bottom. The pressure monitoring component 19 is used to upload the monitored pressure to the control mechanism 20; the control mechanism 20 is used to control the drive motor 17 to work when the uploaded pressure value reaches a preset pressure threshold, so as to lock and fix the insulation reel 30.

[0027] In this embodiment, a pressure monitoring component 19 is provided on the side of the fixed base 11. When the heat preservation quilt reel 30 performs the curtain lowering operation and reaches the bottom, it will press on the pressure monitoring component 19. The pressure monitoring component 19 uploads the monitored pressure to the control mechanism 20. The control mechanism 20 determines that if the current pressure value reaches the preset pressure threshold, it means that the heat preservation quilt reel 30 has been lowered to the bottom, that is, the heat preservation quilt reel 30 is located in the U-shaped area formed by the fixed base 11, the first baffle 12 and the second baffle 13, and the locking and fixing operation can be performed, that is, the control mechanism 20 controls the driving motor 17 of the locking mechanism 10 to work, so as to lock and fix the heat preservation quilt reel 30. Moreover, by setting the pressure threshold, this solution can avoid the malfunction of the locking mechanism 10 caused by the pressure generated by debris, snow and other materials on the pressure monitoring component 19.

[0028] Implementation method three: In this implementation method, it is considered to determine whether the heat preservation quilt reel 30 is lowered into place by monitoring the angle between the two support arms 41 / 42 performing the rolling curtain operation, and trigger the action of the locking mechanism 10 in turn. Specifically, the locking mechanism 10 also includes an angle sensor 110, which is arranged at the connection between the two support arms 41 / 42 of the rolling curtain mechanism 40, and is used to monitor the angle between the two support arms 41 / 42 in real time. The angle sensor 110 is electrically connected to the control mechanism 20 to upload the real-time monitored angle information to the control mechanism 20; the control mechanism 20 is used to control the drive motor 17 to work when the uploaded angle information reaches a preset angle threshold, so as to lock and fix the heat preservation quilt reel 30; wherein, the angle value indicated by the angle threshold can make the heat preservation reel 30 located in the closed area formed by the fixed base 11, the first baffle 12, the second baffle 13 and the locking rod 15.

[0029] In this embodiment, it is considered to set an angle sensor 110 at the connection of the two support arms 41 / 42 that perform the rolling and unrolling operation, so as to monitor the angle information between the two support arms 41 / 42 in real time, and upload the monitored angle information to the control mechanism 20. When the insulation quilt reel 30 is in place, that is, the insulation quilt reel 30 is located in the U-shaped area formed by the fixed base 11, the first baffle 12 and the second baffle 13, it will correspond to an inherent angle range. By setting a suitable angle threshold, the control mechanism 20 can determine whether the current insulation quilt reel 30 is lowered into place. When the monitored angle information reaches the preset angle threshold, it means that the current insulation quilt reel 30 has been lowered into place, and the control mechanism 20 can control the drive motor 17 of the locking mechanism 10 to work, so as to lock and fix the insulation quilt reel 30.

[0030] In order to ensure the locking and fixing effect of the locking mechanism 10 on the insulation quilt roll 30, for each insulation quilt roll 30, the insulation quilt locking devices for the solar greenhouse in this scheme include two, and are respectively arranged at the two ends of the insulation quilt roll 30, so as to lock and fix the two ends of the insulation quilt roll 30 at the same time, thereby ensuring the locking and fixing effect of the insulation quilt roll 30 and minimizing the possibility of the insulation quilt roll 30 swinging due to wind force.

[0031] The control mechanism 20 is also electrically connected to the rolling curtain mechanism 40, and is used to control the operation of the rolling curtain mechanism 40 to drive the heat preservation quilt reel 30 to perform the rolling and unrolling operation, and is used to control the locking mechanism 10 to lock and fix the heat preservation quilt reel 30 when the rolling curtain mechanism 40 stops working after performing the unrolling operation. In other words, the present solution considers realizing the rolling curtain operation and the locking and fixing operation at the same time through a control mechanism 20, which not only makes the equipment structure used in the greenhouse simpler and easier to operate, but also makes the equipment utilization rate higher and the cost required for the equipment lower.

[0032] In addition, in order to facilitate remote control by the operator, in one embodiment, the device further includes a wireless remote controller, which is connected to the control mechanism 20 for remotely issuing the rolling and unrolling curtain operation instructions of the rolling curtain mechanism 40 and the locking and fixing operation instructions of the locking mechanism 10. Of course, a remote client, such as a mobile phone applet, can also be configured to realize remote control of the rolling and unrolling curtain operation and the locking and fixing operation through the remote client.

[0033] The modules or units in the device of the embodiment of the utility model can be combined, divided and deleted according to actual needs. The above disclosure is only the preferred embodiment of the utility model, and of course it cannot be used to limit the scope of the rights of the utility model. Ordinary technicians in this field can understand that all or part of the processes of the above embodiments are implemented, and equivalent changes made according to the claims of the utility model still fall within the scope of the utility model.
