Description

Technical Field

[0001] This utility model relates to the field of agricultural facility technology, and more specifically to a greenhouse with actively regulated temperature. Background Technology

[0002] With the development of agricultural modernization, facility agriculture (such as greenhouses and heated sheds) has been widely used in off-season crop cultivation. Traditional greenhouse temperature control methods mainly rely on coal-fired boilers or electric heating equipment, which have the following problems:

[0003] Inefficient temperature control: Existing greenhouses mostly use single-point temperature monitoring, which cannot accurately reflect the temperature differences in different areas, easily leading to local overheating or undercooling, affecting the uniformity of crop growth.

[0004] High energy consumption: The overall heating method does not take into account regional temperature differences, resulting in serious energy waste, especially with a significant increase in operating costs in low-temperature environments.

[0005] Poor air circulation: The lack of targeted ventilation design leads to excessively high CO2 concentration or humidity inside the greenhouse, which can easily cause pests and diseases. In addition, the traditional fixed installation method of sensors is easily damaged during crop harvesting.

[0006] Low level of automation: Manual control methods are slow to respond, making it difficult to meet the real-time temperature requirements for crop growth, and are also labor-intensive.

[0007] For example, a greenhouse temperature control device disclosed in CN201821056789.2 uses a single thermostat to control the heating equipment, which cannot achieve precise zone control; although the intelligent temperature control greenhouse proposed in CN202020215767.4 adds multiple temperature sensors, it does not solve the problem of coordinated optimization of heating and ventilation systems.

[0008] Therefore, how to provide a greenhouse that can actively regulate temperature by using a dual-temperature sensor matrix for zoned temperature control and graded steam control to achieve precise temperature control is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0009] In view of this, the present invention provides a greenhouse with actively adjustable temperature.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An actively temperature-regulating greenhouse includes a greenhouse roof and multiple temperature regulation matrix units installed inside the greenhouse. Each matrix unit includes a temperature sensor T1 installed on the roof, a temperature sensor T2 installed on the ground, and steam jet nozzles distributed in a cross shape around the temperature sensor T1. The steam jet nozzles are connected to a second pipe via solenoid valves, and the second pipe is fixedly connected to a steam generator via a steam booster pump. The first pipe is installed on both sides of the greenhouse and is also equipped with several solenoid valves. One end of the first pipe passes through the greenhouse and is used to fixally connect to a fan to draw in cold air from inside the greenhouse.

[0012] Preferably, the ceiling temperature sensor T1 is fixedly connected to the wire receiving rod via a secondary line, while the corresponding temperature sensor T2, which is set on the ground, is fixedly connected to the wire receiving rod via a main line.

[0013] Preferably, the ceiling temperature sensor T1 is connected to the main line via a secondary line, and a plurality of main line clips are evenly arranged on the main line. The main line clips are used to adjust the temperature acquisition height of the temperature sensor T1.

[0014] Preferably, the inner diameter of the main line buckle is smaller than the diameter of the secondary line, making it easier for the secondary line to be snapped into the main line buckle.

[0015] Preferably, the second pipe is laid longitudinally along the roof, and the second pipe is divided into several branch pipes that extend vertically downward to each matrix unit. Solenoid valves are installed at the branch pipes that connect the second pipe to the steam jet nozzles.

[0016] Preferably, the steam jet nozzles are arranged in a cross shape around the ceiling temperature sensor T1, with a distance of about 2 meters between them and the front, back, left, and right sides of T1, and each matrix unit is equipped with at least 4 jet nozzles.

[0017] Preferably, the steam level adjustment logic of the steam generator is as follows:

[0018] When T2 < 8℃ and TI < 8℃, steam is set to level 3; when 8℃ ≤ T2 < 20℃ and 8℃ ≤ T1 < 25℃, steam is set to level 2; when 8℃ ≤ T2 < 20℃ and T1 ≥ 25℃, steam is set to level 1; when T2 ≥ 20℃ and T1 is any temperature, steam is set to level 0; level 0 = off, level 1 < level 2 < level 3.

[0019] As can be seen from the above technical solution, compared with the prior art, the active temperature-regulating greenhouse disclosed in this utility model achieves three-dimensional monitoring of the temperature inside the greenhouse through matrix-distributed temperature sensors T1 (roof) and T2 (ground). Each matrix unit independently controls the steam jet nozzle, and intelligent graded regulation significantly reduces energy consumption. In addition, the steam level (0-3) is automatically adjusted according to the temperature combination of T1 and T2, avoiding the crude mode of "full power operation-shutdown" of traditional greenhouses.

[0020] The under-mounted sensor structure improves operational convenience: the roof temperature sensor T1 is height-adjustable via the main line buckle, and the ground temperature sensor T2 can be stored with the main line. During harvesting, the sensors are raised to a safe height to avoid mechanical collision damage.

[0021] Especially suitable for frigid regions where the outdoor ambient temperature is <5℃. In summary, this utility model solves the pain points of traditional greenhouses in terms of temperature control, energy consumption management and ease of operation, and has significant economic and social benefits.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The present invention provides an active temperature-regulating greenhouse, comprising a greenhouse roof 10 and multiple temperature regulation matrix units installed inside the greenhouse. The matrix unit includes a temperature sensor T1 20 installed on the roof, a temperature sensor T2 21 installed on the ground, and steam jet nozzles 30 distributed in a cross shape around the temperature sensor T1 20.

[0029] The steam jet nozzle 30 is connected to the second pipe 52 via the solenoid valve 40, and the second pipe 52 is fixedly connected to the steam generator 80 via the steam booster pump 70.

[0030] The first pipe 51 is respectively installed in the two sides of the shed. The first pipe 51 is also equipped with several solenoid valves 40. One end of the first pipe 51 passes through the shed and is used to fix and connect the fan 60 to draw out the cold air in the shed.

[0031] In this embodiment, the main body of the greenhouse adopts a steel structure frame, and the roof 10 has an arc-shaped light-transmitting design and is covered with a heat-insulating plastic film.

[0032] The interior of the shed is evenly divided into multiple temperature regulation matrix units along its length.

[0033] Furthermore, the matrix unit is specifically arranged as follows: the ceiling temperature sensor T1 20 is fixedly connected to the wire receiving rod 201 via the secondary line 203, and the corresponding temperature sensor T2 21 set on the ground is fixedly connected to the wire receiving rod 201 via the main line 202. Furthermore, the main line 202 and the secondary line 203 are connected to the same wire, and the wire receiving rod 201 is hollow inside to accommodate the main line 202 and the secondary line 203.

[0034] Furthermore, both temperature sensors T1 20 and T2 21 are bottom-mounted for easy harvesting of crops later in the season. Each temperature sensor T2 21, which is set on the ground, has a separate vertical rod installed at its lower end. The ground temperature sensor T2 21 is inserted into the ground at the center of the matrix unit, with the sensor probe 5cm above the ground. It can be raised or lowered with the main line. When the crops mature and are ready for harvesting, the temperature sensor T2 21 can be raised to a certain height by pulling the main line 202, thus avoiding any impact on the later harvesting process.

[0035] Furthermore, the roof temperature sensor T1 20 is connected to the main line 202 via a secondary line 203. Several main line clips 2021 are evenly arranged on the main line 202. The main line clips 2021 are used to adjust the temperature acquisition height of the temperature sensor T1 20. The inner diameter of the main line clip 2021 is smaller than the wire diameter of the secondary line 203, which facilitates the secondary line to be inserted into the main line clip 2021. The secondary line 203 is connected to the main line 202 via the main line clips 2021 and can be adjusted up and down to facilitate adjusting the temperature monitoring position according to the growth height of crops.

[0036] The steam generator 80 is installed on the outside of the greenhouse and is connected to the second pipe 52 via a steam booster pump 70.

[0037] The steam generated by the steam generator 80 is pressurized by the booster pump 70 and then transported to the steam jet nozzles 30 of each matrix unit through the second pipeline 52.

[0038] Furthermore, the second pipe 52 is laid longitudinally along the roof 10. The second pipe 52 is divided into several branch pipes and extends vertically downward to each matrix unit. Solenoid valves 40 are installed at the branch pipes of the second pipe 52 and the steam jet nozzles 30. The valves are controlled to open and close according to the temperature parameters of each matrix unit and the computer instructions at the gas supply end.

[0039] Furthermore, the first pipe 51 is also equipped with several solenoid valves 40. The valves are controlled to open and close according to the temperature parameters of each matrix unit and the instructions of the air supply computer. One end of the first pipe 51 is fixedly connected to a fan 60, and the other end is used to extract cold air and CO2 from the shed.

[0040] Furthermore, the steam jet nozzles 30 are arranged in a cross shape around the ceiling temperature sensor T1 20, about 2 meters apart from T1 in all directions. Each matrix unit is equipped with at least 4 jet nozzles, with the jet direction diagonally downward, covering the entire area of ​​the matrix unit.

[0041] The above system is suitable for outdoor temperatures below 5°C.

[0042] In use, the steam level adjustment logic of the steam generator 80 is as follows:

[0043] When T2 < 8℃ and TI < 8℃, steam should be set to level 3.

[0044] When 8℃≤T2<20℃ and 8℃≤T1<25℃, steam should be set to level 2.

[0045] When 8℃≤T2<20℃ and T1≥25℃, steam level 1;

[0046] When T2 ≥ 20℃ and T1 is any temperature, steam setting 0;

[0047] 0 gear = stop, 1 gear < 2 gear < 3 gear.

[0048] This utility model discloses a greenhouse with active temperature regulation. Through a matrix distribution of temperature sensors T1 (roof) and T2 (ground), it achieves three-dimensional monitoring of the temperature inside the greenhouse. Each matrix unit independently controls the steam jet nozzle 30, enabling intelligent graded regulation and significantly reducing energy consumption. In addition, it automatically adjusts the steam level (0-3) according to the temperature combination of T1 and T2, avoiding the crude mode of "full power operation-shutdown" of traditional greenhouses.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
