[0002] A vegetable growing greenhouse is an agricultural facility with excellent thermal insulation performance. It provides a relatively stable and warm environment for vegetable growth. However, in the cold winter, the temperature in the greenhouse may still drop, which will have an adverse effect on the growth and development of vegetables. Therefore, a vegetable growing greenhouse antifreeze and thermal insulation device is needed to protect vegetables from damage by low temperatures.
[0003] Existing antifreeze and insulation devices for vegetable planting greenhouses usually use manual operation to cover and remove the insulation film. Farmers need to go to the outside of the greenhouse and cover the insulation film on the greenhouse to protect the vegetables from the influence of low temperature. This method requires farmers to spend a lot of time and physical strength, especially in the case of large-scale planting. The operation process is cumbersome and inefficient. Utility Model Content
[0004] The purpose of the utility model is to solve the problem of low planting efficiency due to the need for farmers to roll up the insulation film during the use of the antifreeze and heat preservation device, thereby proposing an antifreeze and heat preservation device for vegetable planting greenhouses.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an antifreeze and heat preservation device for a vegetable planting greenhouse, comprising a greenhouse body, a greenhouse roof fixedly installed on the top of the greenhouse body, two groups of slide rails fixedly installed on the top of the greenhouse roof, sliding grooves are opened on the tops of the two groups of slide rails, pulleys are slidably embedded in the inner surface walls of the two groups of sliding grooves, one side of the outer wall of the two groups of pulleys is fixedly connected with a first rotating shaft, the outer wall of the two groups of the first rotating shafts are movably sleeved with bearings, connecting plates are fixedly connected between the outer walls of the two groups of bearings, one side of the outer wall of the two connecting plates is fixedly installed with traction hooks, the bottom of the two connecting plates is fixedly connected with a heat preservation film, the inside of the two heat preservation films is fixedly inserted with a second rotating shaft, and the outer wall of the two second rotating shafts is movably sleeved with a first fixed plate.

[0008] Preferably, the output ends of the two second motors are fixedly connected to a third rotating shaft, and the outer walls of the two third rotating shafts are movably sleeved with two second fixing plates.
[0009] Preferably, a solar panel is fixedly mounted on the top of the shed roof, an electric heating pipe is fixedly mounted on the inner surface wall of the shed body, and a partition is fixedly mounted on the bottom of the inner wall of the shed body.
[0010] Preferably, two first blowers are fixedly mounted on one side of the outer wall of the partition, and two second blowers are fixedly mounted on the other side of the outer wall of the partition.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:
[0013] In the utility model, through the interaction of various components of the device, when night falls and the temperature gradually drops, the controller will receive a signal and drive the motor to start working. The rotation of the motor drives the rotating shaft to reel in the traction rope, slowly unfolding the thermal insulation film and covering the top of the greenhouse. This process will continue until the entire roof is completely covered with the thermal insulation film, thereby effectively maintaining the temperature in the greenhouse and reducing temperature loss. The traction of the rope ensures the stability and uniformity of the unfolding of the thermal insulation film, making the coverage of the top of the greenhouse smoother and tighter, and according to the outside temperature, the switching and retraction speed of the thermal insulation film can be intelligently controlled to keep the greenhouse in the best growth environment at all times.
[0014] In the utility model, through the interaction of various components of the device, the solar panel can convert solar energy into electrical energy, provide renewable energy for the entire device, and reduce the dependence on traditional power resources. When the temperature in the greenhouse is too low, the temperature sensor will transmit a signal to the controller. After receiving the signal, the controller will start the electric heating tube and the first and second blowers. The heating function of the electric heating tube can increase the temperature in the greenhouse, and the operation of the first blower and the second blower can circulate the hot air inside the greenhouse, thereby effectively preventing the temperature stratification in the greenhouse and ensuring that the temperature in every corner remains consistent.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides an antifreeze and heat preservation device for a vegetable planting greenhouse, comprising a greenhouse body 1, a greenhouse roof 2 is fixedly installed on the top of the greenhouse body 1, two groups of slide rails 3 are fixedly installed on the top of the greenhouse roof 2, the tops of the two groups of slide rails 3 are provided with sliding grooves 4, the inner surface walls of the two groups of sliding grooves 4 are slidably embedded with pulleys 5, one side of the outer wall of the two groups of pulleys 5 is fixedly connected with a first rotating shaft 6, the outer wall of the two groups of first rotating shafts 6 is movably sleeved with bearings 7, a connecting plate 8 is fixedly connected between the outer walls of the two groups of bearings 7, one side of the outer wall of the two connecting plates 8 is fixedly installed with a traction hook 9, the bottom of the two connecting plates 8 is fixedly connected with a heat preservation film 10, and the two A second rotating shaft 11 is fixedly inserted inside each insulation film 10, and the outer walls of the two second rotating shafts 11 are movably sleeved with a first fixed plate 12, one side of the outer walls of the two second rotating shafts 11 is fixedly connected to a first motor 13, a controller 14 is fixedly installed on one side of the outer wall of the shed body 1, a guide wheel 15 is fixedly installed on one side of the outer wall of the shed body 1, two support plates 16 are fixedly installed on the outer wall of the shed body 1, and second motors 17 are fixedly installed on the top of the two support plates 16, the output ends of the two second motors 17 are fixedly connected to a third rotating shaft 18, and the outer walls of the two third rotating shafts 18 are movably sleeved with two second fixed plates 19.
[0024] The effect achieved by the entire embodiment 1 is that, first, one end of the two traction ropes is fixed inside the two traction hooks 9 respectively, and then the other ends of the two traction ropes are respectively wound tightly with the two third rotating shafts 18. When the temperature drops at night, the controller 14 starts the two second motors 17, and the output ends of the two second motors 17 start to rotate at a uniform speed. The output ends of the two second motors 17 drive the two third rotating shafts 18 to rotate. As the two third rotating shafts 18 rotate, they will gather the two traction ropes. At the same time, the two guide wheels 15 fix the traction direction. The two traction ropes are pulled during the gathering process. The two connecting plates 8 are moved downward, and the two connecting plates 8 drive the four pulleys 5 to move on the inner surface wall of the sliding groove 4. The function of the bearing 7 is to prevent the connecting plates 8 from rotating with the pulleys 5. When the connecting plates 8 move, they drive the thermal insulation film 10 to cover the roof 2. When the pulley 5 moves to the bottom of the slide rail 3, the thermal insulation film 10 covers the roof 2. When it is sunny, the controller 14 starts the first motor 13. The output end of the first motor 13 drives the second rotating shaft 11 to rotate. The rotating second rotating shaft 11 drives the thermal insulation film 10 to rotate, thereby completing the winding of the thermal insulation film 10.
[0025] Embodiment 2, as Figure 2-Figure 4As shown, a solar panel 20 is fixedly installed on the top of the roof 2, an electric heating tube 21 is fixedly installed on the inner wall of the shed body 1, a partition 22 is fixedly installed on the bottom of the inner wall of the shed body 1, two first blowers 23 are fixedly installed on one side of the outer wall of the partition 22, two second blowers 24 are fixedly installed on the other side of the outer wall of the partition 22, a temperature sensor 25 is fixedly installed on one side of the outer wall of the partition 22, two sets of hinges 26 are fixedly installed on one side of the outer wall of the shed body 1, a shed door 27 is fixedly connected between the rotating ends of the two sets of hinges 26, and a handle 28 is fixedly installed on one side of the outer wall of the shed door 27.
[0026] The effect achieved by the entire embodiment 2 is that, first, in sunny weather, the solar panel 20 will make full use of the sunlight, convert its energy into electrical energy and store it, providing renewable energy for the subsequent heating process. When the temperature inside the shed 1 is too low, the temperature sensor 25 will sense this situation and transmit the signal to the controller 14. After receiving the signal, the controller 14 will take corresponding actions. It first starts the electric heating tube 21, and the electric power provided by the solar panel 20 causes the electric heating tube 21 to generate heat energy. At this time, the temperature inside the shed 1 can be effectively improved. At the same time, the controller 14 will also start the first blower 23 and the second blower 24. The first blower 23 will suck in the hot air and blow it into the right side space of the partition 22. When the hot air moves to one side of the outer wall of the partition 22, the second blower 24 will take over and suck the hot air into the other side space of the partition 22. At this time, the hot air forms a cycle inside the shed 1, making the internal temperature distribution more uniform.
[0027] Working principle: Before using the device, first fix one end of the two traction ropes inside the two traction hooks 9, and the other end is tightly wound with the two third rotating shafts 18. When night falls and the temperature gradually decreases, the controller 14 will start the two second motors 17. After the second motors 17 start to rotate at a stable speed, they will drive the two third rotating shafts 18 to rotate. With the rotation of the two third rotating shafts 18, the traction ropes are gradually retracted. At the same time, the two guide wheels 15 ensure the consistency of the traction direction. In the process of the traction ropes being retracted, the connecting plate 8 will move along the The connecting plate 8 moves downward in the direction of the guide wheel 15, and the movement of the connecting plate 8 drives the four pulleys 5 to move on the inner surface walls of the four sliding grooves 4. The function of the bearing 7 is to prevent the connecting plate 8 from rotating with the rotation of the pulley 5, so as to ensure that the connecting plate 8 can move stably. When the connecting plate 8 moves, it drives the thermal insulation film 10 to cover the roof 2. When the pulley 5 moves to the bottom of the slide rail 3, the thermal insulation film 10 completely covers the roof 2, thereby effectively maintaining the temperature in the shed. When there is sufficient sunlight, the solar panel 20 fully absorbs the sunlight and converts it into electrical energy for storage. The controller 14 starts the first motor 13, and the output end of the first motor 13 drives the second rotating shaft 11 to rotate. The rotation of the second rotating shaft 11 drives the thermal insulation film 10 to rotate. In this way, the thermal insulation film 10 can be rolled up. When the temperature inside the shed 1 is too high, the temperature sensor 25 detects this and sends a signal to the controller 14. After receiving the signal, the controller 14 first starts the electric heating tube 21 and provides it with power through the solar panel 20, so that the electric heating tube 21 is heated. The heat pipe 21 generates heat energy, so that the temperature inside the greenhouse 1 can be effectively improved. At the same time, the controller 14 also starts the first blower 23 and the second blower 24. The first blower 23 sucks the hot air and blows it into the right side space of the partition 22. When the hot air moves to the other side of the partition 22, the second blower 24 takes over and sucks the hot air into the left side space of the partition 22. Under the action of the first blower 23 and the second blower 24, the hot air forms an air circulation inside the greenhouse, so that the hot air can be evenly distributed inside the greenhouse to prevent the occurrence of temperature stratification.
