DETAILED DESCRIPTION

[0040] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work fall within the scope of protection of the present application.

[0041] The quilt mechanism provided by the present application will be described below in combination with the drawings. Figures 1-7 A quilt mechanism is described in the present application. The quilt mechanism comprises a support 1, a first winding pipe 2, a second winding pipe 3, a first driving device 4 and a second driving device 5.

[0042] The one end of the heat preservation material 6 is fixed to one end of the support 1; the first winding pipe 2 is arranged on the other end side of the support 1 and horizontally hangs down, and the one end of the light transmission material 7 is wound on the first winding pipe 2; the second winding pipe 3 is rotatably arranged on the support 1, and the other end of the heat preservation material 6 and the other end of the light transmission material 7 are wound on the second winding pipe 3; the first driving device 4 is drivingly connected with the first winding pipe 2, and is used for driving the first winding pipe 2 to rotate; the second driving device 5 is drivingly connected with the second winding pipe 3, and is used for driving the second winding pipe 3 to roll along the winding direction.

[0043] Specifically, the support 1 is used as the overall support of the winding mechanism, is composed of four supporting legs and two cross beams, the two cross beams are arranged in parallel and are connected between the two supporting legs respectively, the two ends of the first winding pipe 2 are lapped on the two cross beams and can move along the length direction of the cross beam, that is, the winding direction. The one end of the heat preservation material 6 is fixed to one end of the support 1, and the other end is wound on the second winding pipe 3 and can be rolled up and rolled off along with the movement of the second winding pipe 3. The second winding pipe 3 moves along the cross beam direction under the driving of the second driving device 5, and drives the second winding pipe 3 to realize the rolling up of the heat preservation material 6 and the light transmission material 7 on the cross beam. The first winding pipe 2 is arranged on the other side of the support 1, the one end of the light transmission material 7 is wound on the first winding pipe 2, and the other end is wound on the second winding pipe 3. The part of the light transmission material 7 on the cross beam realizes rolling up and rolling off along with the movement of the second winding pipe 3, and the part on the other side of the support 1 realizes rolling up and rolling off through the first winding pipe 2. It can be understood that, since the movement of the second winding pipe 3 will drive the rolling up of the light transmission material 7, in order to ensure that the tension of the light transmission material 7 is in a suitable range, the other end also needs to be rolled up accordingly. Therefore, the first winding pipe 2 rotates under the driving of the first driving device 4, so that the light transmission material 7 is extended from the first winding pipe 2 and is recovered.

[0044] The winding mechanism of the embodiment at least includes the following two working states:

[0045] 1. Taking the rolling up process of the heat preservation material 6 as an example:

[0046] The second driving device 5 rotates forward, the second winding pipe 3 moves and rolls up the heat preservation material 6 and the light transmission material 7 on the second winding pipe 3 in the rolling up process. In the rolling up process, the first winding pipe 2 and the first driving device 4 have a tendency to move upward due to the pulling action of the light transmission material 7. At this time, the first driving device 4 can be correspondingly started in reverse to make the first winding pipe 2 roll off and supply the light transmission material 7, so as to ensure that the first winding pipe 2 and the first driving device 4 are in a relatively stable height position. When the rolling up of the heat preservation material 6 is completed, at this time, the second driving device 5 and the second winding pipe 3 are moved to the end of the support 1 where the heat preservation material 6 is fixed, the heat preservation material 6 is in a rolled up state, and at the same time, the light transmission material 7 is laid on the support 1, the winding mechanism has good light transmission, and is suitable for being adjusted to this working state in the daytime.

[0047] 2. Taking the unwinding process of the thermal insulation material 6 as an example:

[0048] The second driving device 5 reversely rotates, and the second winding pipe 3 moves and the thermal insulation material 6 and the light-transmitting material 7 are simultaneously unwound from the second winding pipe 3 in the unwinding process. In the unwinding process, the first winding pipe 2 and the first driving device 4 have a downward moving tendency due to the release of the light-transmitting material 7, at this time, the first driving device 4 can be correspondingly started in a forward direction, so that the first winding pipe 2 is wound, and the transparent material roll is wound onto the first winding pipe 2, which can ensure that the first winding pipe 2 and the first driving device 4 are at a relatively stable height position. When the unwinding of the thermal insulation material 6 is completed, at this time, the second driving device 5 and the second winding pipe 3 are both moved to the end of the support 1 fixed with the light-transmitting material 7, and the light-transmitting material 7 is in a wound state, at the same time, the thermal insulation material 6 is laid flat on the support 1, and the roll winding mechanism has good thermal insulation property, which is suitable for adjusting to this working state at night.

[0049] Further, the first driving device 4 and the second driving device 5 can both adopt a driving mode of a motor, and a speed reducer is configured, and an output shaft of the speed reducer is drivingly connected with the corresponding winding pipe.

[0050] The roll winding mechanism provided by the application drives the second winding pipe 3 to rotate and move on the support 1 through the second driving device 5, and simultaneously realizes the winding and unwinding of the thermal insulation material 6 and the light-transmitting material 7 on the support 1, drives the first winding pipe 2 to rotate through the first driving device 4, so that the height of the first winding pipe 2 driven by the first driving device 4 is stable, and in the winding and unwinding process of the thermal insulation material 6 and the light-transmitting material 7, the effects of transmitting light in the daytime and keeping warm at night can be realized; and the first winding pipe 2 is horizontally arranged on one side of the support 1, all the weight of the first winding pipe 2 is evenly distributed on the second winding pipe 3 in the length direction of the second winding pipe 3, and the thermal insulation material 6 is always pulled towards the first winding pipe 2 in the winding and unwinding process, so that the thermal insulation material 6 can always be straightened, the consistency of the second winding pipe 3 in action is realized, and the situation of skewing and bending is avoided.

[0051] In one embodiment of the application, the roll winding mechanism further comprises a guide rod 8, the guide rod 8 is arranged on the side of the support 1 in the winding direction, and the second driving device 5 is slidingly arranged on the guide rod 8. In this embodiment, the two ends of the guide rod 8 are arranged on the upper ends of the two support legs on the same side of the support 1, the guide rod 8 can be horizontally arranged, and the second driving device 5 is slidingly arranged along the guide rod 8, when the second driving device 5 drives the second winding pipe 3 to rotate on the support 1, the second driving device 5 moves along the guide rod 8 with the second winding pipe 3. It can be understood that the length direction of the guide rod 8 is the winding direction.

[0052] In one of the embodiments of the present application, the winding mechanism further comprises a switch device 9 connected with the first driving device 4 for controlling the working state of the first driving device 4. Specifically, the switch device 9 can take the following two forms.

[0053] In one of the embodiments of the present application, as shown in Figure 7 the switch device 9 comprises a baffle 91, a first limit switch 92 and a second limit switch 93. The baffle 91 is fixed on the side of the support close to the first winding pipe 2. The first limit switch 92 is fixed on the first driving device 4, and is switched between the triggered state and the untriggered state by cooperating with the baffle 91. The first limit switch 92 is electrically connected with the first driving device 4 for controlling the working state of the first driving device 4 when the thermal insulation material 6 is in the winding state. The second limit switch 93 is fixed on the first driving device 4, and is switched between the triggered state and the untriggered state by cooperating with the baffle 91. The second limit switch 93 is electrically connected with the first driving device 4 for controlling the working state of the first driving device 4 when the thermal insulation material 6 is in the unwinding state. In this embodiment, the first limit switch 92 and the second limit switch 93 detect the approaching state of the baffle 91, and the first limit switch 92 and the second limit switch 93 detect the approaching state of the baffle 91 to control the start or stop of the first driving device 4, so as to ensure that the first driving device 4 and the first winding pipe 2 are in the relatively stable height position. The working state of the first driving device 4 in the process of winding and unwinding the thermal insulation material 6 is described as follows.

[0054] 1. Taking the winding process of insulation material 6 as an example: The first drive device 4 is de-energized, the first limit switch 92 is a normally open limit switch and is in an untriggered state, that is, the first limit switch 92 is away from the baffle 91. The second drive device 5 rotates in the forward direction, the second roll tube 3 moves and during the winding process, the insulation material 6 and the light-transmitting material 7 are simultaneously wound onto the second roll tube 3. During the winding process, the first roll 2 and the first drive device 4 move upward due to the pulling effect of the light-transmitting material 7. The first limit switch 92 approaches the baffle 91. When the first limit switch 92 touches the baffle 91, it triggers the switch. At this time, the control starts the first drive device 4 to rotate in the opposite direction, so that the first roll 2 is unwound. The unwinding speed of the first roll 2 is always set to be greater than the winding speed of the second roll 3. Then the first roll 2 and the first drive device 4 move downward as a whole. When the first limit switch 92 moves away from the baffle 91 again, the first limit switch 92 is in an untriggered state, the first drive device 4 is de-energized, and the first roll 2 stops unwinding. At this time, the first roll 2 and the first drive device 4 will move upward as a whole again, realizing the dynamic height position balance of the first roll 2 and the first drive device 4. By repeating the above process, the first roll 2 and the first drive device 4 can be kept in a relatively stable height position during the winding process of the insulation material 6.

[0055] 2. Taking the unwinding process of insulation material 6 as an example: The first drive device 4 is de-energized, and the second limit switch 93, which is a normally closed limit switch, is in the triggered state, i.e., the second limit switch 93 is close to the baffle 91. The second drive device 5 rotates in the reverse direction, the second roll tube 3 moves, and during the unwinding process, the insulation material 6 and the light-transmitting material 7 are simultaneously unwound by the second roll tube 3. During the unwinding process, the first roll tube 2 and the first drive device 4 move downward due to the release of the light-transmitting material 7, and the second limit switch 93 moves away from the baffle 91 and becomes non-triggered. At this time, the control starts the first drive device 4 to rotate forward, so that the first roll tube 2 is wound up and the winding speed of the first roll tube 2 is always greater than the unwinding speed of the second roll tube 3. Then the first roll tube 2 and the first drive device 4 move upward as a whole. When the first limit switch 92 is close to the baffle 91 again, the first limit switch 92 is in the triggered state, the first drive device 4 is de-energized, the first roll tube 2 stops winding up, and at this time, the first roll tube 2 and the first drive device 4 will move downward as a whole again. By repeating the above process, the first roll tube 2 and the first driving device 4 can be kept at a relatively stable height during the unwinding process of the insulation material 6.

[0056] In one embodiment of the present invention, the switching device 9 includes a tension sensor and a switch. The tension sensor is positioned close to the light-transmitting material 7; the switch is electrically connected to both the tension sensor and the first driving device 4, and is used to control the operating state of the first driving device 4 based on the tension of the light-transmitting material 7. In this embodiment, the tension sensor detects the tension level of the light-transmitting material 7. If the tension of the light-transmitting material 7 is high, the switch controls the first driving device 4 to rotate forward to release the light-transmitting material 7 to prevent it from being pulled, deformed, or even broken. If the tension of the light-transmitting material 7 is low, the switch controls the first driving device 4 to rotate in the opposite direction to retract the light-transmitting material 7, making it taut. Preferably, the switch can be a solenoid valve.

[0057] In one embodiment of the present invention, the rolling mechanism further includes an elastic element, one end of which is fixed to the bracket 1, and the other end of which is connected to the first driving device 4, for balancing the weight of the first driving device 4. Specifically, the elastic element is preferably a spring, one end of which is fixedly connected to the bracket 1, and the other end of which is fixedly connected to the first driving device 4. The elastic force provided by the spring balances the weight of the first driving device 4, preventing the light-transmitting material 7 from being stretched and deformed due to the excessive weight of the first driving device 4.

[0058] In one embodiment of the present invention, the roll-up mechanism further includes: a third driving device 10, wherein the second driving device 5 and the third driving device 10 are respectively disposed at both ends of the second roll tube 3 and are respectively drivenly connected to the second roll tube 3 for driving the second roll tube 3 to roll along the roll-up direction. Figure 3 As shown, driving devices are respectively installed at both ends of the second roll tube 3 for driving, namely the second driving device 5 and the third driving device 10 in this embodiment. By rotating synchronously, the rotation speed at both ends of the second roll tube 3 is consistent, and the load on a single driving device can be reduced. When the length of the second roll tube 3 is long, it also ensures that the movement of the second roll tube 3 is smooth, and the light-transmitting material 7 and the heat-insulating material 6 are laid flat. It should be understood that if two driving devices are used to drive the second roll tube 3, then two guide rods 8 also need to be set accordingly, that is, one guide rod 8 is set on each side of the bracket 1 to guide the second driving device 5 and the third driving device 10 respectively.

[0059] In one embodiment of the present invention, the winding mechanism further includes a fourth driving device 11. The first driving device 4 and the fourth driving device 11 are respectively disposed at both ends of the first winding tube 2 and are respectively drivenly connected to the first winding tube 2 to drive the first winding tube 2 to rotate. Figure 2As shown, the first winding pipe 2 is driven by the first driving device 4 and the fourth driving device 11, and the second winding pipe 3 is driven by the second driving device 5 and the third driving device 10.

[0060] Further, as shown, Figure 4 As shown, the first winding pipe 2 is driven by the first driving device 4 and the fourth driving device 11, and the second winding pipe 3 is driven by the second driving device 5 and the third driving device 10.

[0061] In one embodiment of the present application, the heat preservation material 6 comprises a thermal blanket, and the light transmission material 7 comprises any one of a film, a sunshade net and a curtain. In this embodiment, the heat preservation material 6 is in the form of a thermal blanket, and the light transmission material 7 can be any one of a film, a sunshade net and a curtain according to the need of light transmission. It should be understood that the heat preservation material 6 and the light transmission material 7 can be replaced by suitable materials according to actual conditions to meet the respective needs of heat preservation and light transmission.

[0062] The present application also provides a greenhouse. The greenhouse comprises the heat preservation material 6, the light transmission material 7 and the quilt mechanism in the above embodiments of the present application. Generally, the quilt mechanism in the above embodiments is arranged at the top of the greenhouse, and the heat preservation material 6 and the light transmission material 7 are wound and unwound by the quilt mechanism, so as to meet the needs of light transmission and heat preservation of the greenhouse.

[0063] As disclosed above, one end of the heat preservation material 6 is fixed to one end of the support 1, one end of the light transmission material 7 is wound on the other side of the support 1 by the first winding pipe 2, and the other ends of the heat preservation material 6 and the light transmission material 7 are wound on the second winding pipe 3.
