Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses, in particular to a greenhouse. Background Art

[0002] Greenhouse is also called hot house. It is a facility that can let in light, keep warm (or heat), and is used to grow plants. In seasons that are not suitable for plant growth, it can provide a greenhouse growth period and increase production. It is mostly used for the cultivation or seedling raising of temperature-loving vegetables, flowers, trees, and other plants in low temperature seasons.

[0003] However, the structural design of existing greenhouses fails to fully consider the factors of light and temperature, resulting in less than ideal environmental control in the greenhouse, affecting the growth and yield of crops. At the same time, the greenhouse roof cannot be automatically opened and closed according to actual conditions, and needs to be opened manually, which is very inconvenient. In response to this, the prior art has further developed a technical solution for opening and closing greenhouses through hydraulic equipment, such as the solution with application number 201810080985.1 and patent name "A Temperature-Controlled Vegetable Planting Greenhouse", which uses hydraulic telescopic rods and hydraulic pumps to drive the greenhouse to open and close. However, the cost of hydraulic telescopic rods, hydraulic pumps and other equipment is too high and difficult to maintain, which is not conducive to reducing costs and increasing efficiency in agricultural production.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0024] Reference Figure 1-5 The present embodiment provides a greenhouse, including a shed 1, a top frame 2 is installed in the middle of the top of the shed 1, the top frame 2 is clamped on the top of the shed 1, a support plate 17 is clamped on the top of the top frame 2, a top shaft 7 is inserted on the top of the support plate 17, a bottom arc plate 8 is clamped in the middle of the top shaft 7, a top arc plate 9 is clamped on the top of the top shaft 7, a clamping area 5 is provided in the gap between the top arc plate 9 and the bottom arc plate 8, and a light sensor 6 is installed in the middle of the top of the top arc plate 9.

[0025] exist Figure 1 The middle is the state where the top of the greenhouse is open. When it is opened, the top area will be open, and the external sunlight will shine in, and the internal heat can also be dissipated. The light sensor 6 is an existing device, which is used to detect the light intensity in real time and convert the light intensity value into a voltage value.

[0026] Furthermore, an output threaded shaft 16 is installed in the middle of the bottom end of the support plate 17, and the bottom end of the output threaded shaft 16 is transmission-connected to the drive motor group 12. A limiting seat 18 is clamped on the outside of the output threaded shaft 16 near the top of the drive motor group 12, and side sliding rods 19 are threadedly connected on both sides of the output threaded shaft 16, and the inner walls on both sides of the top frame 2 and the side sliding rods 19 are slidably connected.

[0027] Furthermore, the driving motor group 12 includes a motor body (such as a servo motor) and a motor controller. The motor controller can be controlled by a remote mobile terminal, and the bottom end of the driving motor group 12 is electrically connected to a temperature sensor 20, which is used to detect the temperature in the shed.

[0028] The two sides of the lifting ring 14 are threadedly connected with the main push rod 15, the top of the main push rod 15 is connected to the linkage strut 3, the top of the main push rod 15 is connected to the head end of the linkage strut 3, and the middle and bottom of the outside of the main push rod 15 are connected to the auxiliary push rod 13, the end of the middle auxiliary push rod 13 is connected to the middle end connection of the linkage strut 3, and the end of the bottom auxiliary push rod 13 is connected to the end connection of the linkage strut 3.

[0029] The driving motor group 12 can drive the output threaded shaft 16 at the top to rotate clockwise and counterclockwise. When the output threaded shaft 16 rotates clockwise, the external lifting ring 14 will descend. When the output threaded shaft 16 rotates counterclockwise, the external lifting ring 14 will rise. The side sliding rods 19 on both sides of the lifting ring 14 can play a limiting role. The lifting ring 14 will not rotate on its own. When the lifting ring 14 rises, it will push the head end of the linkage support rod 3 through the main push rod 15, and the lifting ring 14 will be lifted up through the upper middle part of the main push rod 15. The secondary push rod 13 pushes the middle part of the linkage support rod 3, and the secondary push rod 13 at the lower end of the main push rod 15 pushes the end of the linkage support rod 3. When the lifting ring 14 descends, the linkage support rod 3 will be pulled to shrink and descend. The folding shelf 4 and the linkage support rod 3 are connected and adapted to each other. When the linkage support rod 3 is extended or retracted, the folding shelf 4 will be driven to extend or retract. When the folding shelf 4 is extended or retracted, the film laid on the surface of the folding shelf 4 will also be extended or retracted. After the folding shelf 4 is pushed up, it will be directly stuck in the card area 5, and the top of the greenhouse will be covered.

[0030] At the same time, when the light sensor 6 senses that the external light intensity reaches a preset value, it will transmit a command signal to the controller of the drive motor group 12 through the built-in MCU. After receiving the signal, the controller of the drive motor group 12 will control the motor to drive the output threaded shaft 16 to rotate counterclockwise, and then the external lifting ring 14 will drop. After the lifting ring 14 drops, it will drive the top shelf to drop and shrink through the main push rod 15 and the auxiliary push rod 13 on the side, thereby exposing the middle area of ​​the top. In actual practical use, if the plants inside are positive plants, the light intensity activated by induction is about 20000-25000KLX, and if the plants planted inside are negative plants, the light intensity activated by induction is about 5000-10000KLX. After the light is reduced below this range, the light sensor 6 will transmit a closing command signal to the motor group.

[0031] At the same time, the temperature sensor 20 at the bottom of the driving motor group 12 will detect the temperature inside the greenhouse. When the temperature exceeds 30°C, the transmission chip inside the sensor will transmit an opening command signal to the controller of the driving motor group 12. Then the controller 12 will control the output threaded shaft 16 to rotate clockwise through the driving motor group 12, so that the external lifting ring 14 will indirectly drive the top of the greenhouse to open. Specific embodiment 2:

[0033] The difference between this embodiment and the first embodiment is that the top end of the linkage support rod 3 is clamped with a folding shelf 4, the middle of the folding shelf 4 is provided with a fold 11, and a film is laid on the top of the folding shelf 4. The folding shelf 4 and the linkage support rod 3 are multi-section, and the supporting structures on both sides are similar to the structure of an open umbrella.

[0034] At the same time, a mounting slot 10 is provided at the bottom of the folding shelf 4 , and the mounting slot 10 and the linkage support rod 3 are adapted to each other.

[0035] To sum up, the greenhouse in the present application can be automatically opened and closed according to light and temperature. At the same time, its opening and closing structure mainly includes threaded shafts, lifting rings, side sliding rods, main push rods, auxiliary push rods and other structures, which are all conventional components and do not require complex equipment such as hydraulics. The control process is simple, which can greatly reduce the cost of use.
