Description

Technical Field

[0001] This utility model relates to the field of vegetable planting technology, specifically to a light and temperature regulation device for green vegetable planting greenhouses. Background Technology

[0002] With the increasing demand for large-scale green vegetable cultivation, greenhouses, as controllable cultivation carriers, directly affect the vegetable growth cycle, yield, and quality through their light and temperature regulation effects.

[0003] Publication (Announcement) No.: CN220211201U describes an automated shading device for a temperature-controlled greenhouse, comprising: "a temperature-controlled greenhouse body, a light sensor installed on the upper surface of the internal frame of the temperature-controlled greenhouse body, a temperature sensor installed on the right side wall inside the temperature-controlled greenhouse body, two front-to-back support plates installed on the right end of the top of the temperature-controlled greenhouse body, two front-to-back support columns arranged on the left side of the temperature-controlled greenhouse body, and a shading mechanism between the two support plates and the two support columns." Its beneficial effect is that when multiple gears rotate, they drive multiple rotating rods and shading plates to rotate, thereby adjusting the angles of multiple shading plates according to the temperature and light intensity inside the temperature-controlled greenhouse, achieving the effect of adjusting the amount of light in the temperature-controlled greenhouse.

[0004] However, existing technologies that rely solely on shading panels to regulate light and temperature have drawbacks: they depend on a single method of shading panels; adjustments require manual operation or simple mechanical handling; the response is slow; and it is difficult to dynamically adjust the shading rate based on real-time light intensity and temperature. This can easily lead to insufficient shading causing high temperatures inside the greenhouse, or excessive shading causing insufficient light. To address this, we propose a light and temperature regulation device for green vegetable greenhouses. Utility Model Content

[0005] The purpose of this invention is to provide a light and temperature regulation device for green vegetable greenhouses to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a light and temperature regulation device for a green vegetable planting greenhouse, comprising a ground main body and a greenhouse body, wherein a plurality of longitudinal and transverse frames are respectively laid and installed at the inner end of the greenhouse body;

[0007] A water storage tank is installed on one side of the greenhouse body. A water source heat pump temperature regulating unit is installed on the outer wall of the water storage tank. The water source heat pump temperature regulating unit includes a cooling and heating pump body. A controller is installed on the top of the cooling and heating pump body. A refrigerant conduit installed inside the greenhouse body is fixedly connected to the output end of the cooling and heating pump body. Several U-shaped frames are inserted on both inner sides of the greenhouse body. Elastic connecting ropes are fixedly connected between the U-shaped frames. Inclined grooves with interference fit to the refrigerant conduit are opened on both sides of the U-shaped frames.

[0008] Preferably, a temperature sensor is installed on the upper end of each of the longitudinal frame sidewalls, and the temperature sensor is electrically connected to the controller.

[0009] Preferably, the refrigerant conduit is distributed in a continuous curved shape at the inner end of the greenhouse body, and the transverse frame and the refrigerant conduit are both wrapped with limiting ropes, and the section of the refrigerant conduit that seeps into the ground is arranged in a spiral shape.

[0010] Preferably, the water source heat pump type water temperature regulating unit and the water storage tank located at both ends of the greenhouse body are staggered, and the top of the water storage tank is respectively embedded with a water inlet pipe.

[0011] Preferably, each of the U-shaped inserts has a handle fixedly connected to its top.

[0012] Compared with the prior art, this utility model

[0013] Beneficial effect 1: Through the electrical connection between the temperature sensor on the longitudinal frame and the controller, temperature data of different areas inside the greenhouse can be collected in real time. The controller can automatically adjust the operation of the cooling and heating pumps according to the preset threshold to achieve intelligent switching between "heating up" and "cooling down". At the same time, the continuous curved distribution of the refrigerant pipes increases the contact area with the air inside the greenhouse, and the spiral setting on the ground section prolongs the flow time of the refrigerant water. This not only strengthens the regulation of soil temperature (making the temperature distribution inside the greenhouse more uniform), but also helps to regulate the air temperature inside the greenhouse, making the temperature control more in line with the needs of different growth stages of green vegetables and ensuring the stability of crop growth.

[0014] Benefit 2: Flexible and convenient installation and maintenance, reducing operating costs: The U-shaped insertion frame is interference-fitted with the refrigerant pipe through the inclined groove, and the top handle can quickly complete the installation and disassembly of the pipe. The elastic connecting rope between adjacent insertion frames can also flexibly adjust the installation spacing and facilitate storage. Attached Figure Description

[0022] 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.

[0023] like Figures 1-6 As shown, this utility model provides the following technical solution:

[0024] Example 1: A light and temperature regulation device for a green vegetable greenhouse, comprising a ground body 1 and a greenhouse body 2. Several longitudinal frames 21 and transverse frames 22 are laid and installed on the inner end of the greenhouse body 2. Temperature sensors 210 are installed on the upper side walls of the several longitudinal frames 21.

[0025] Among them, the temperature sensor 210 can monitor the temperature inside the greenhouse body 2 in real time, and the longitudinal frame 21 and the transverse frame 22 can provide stable support for the greenhouse body 2.

[0026] In use, green vegetables are planted on the main ground structure 1, and the greenhouse body 2 forms a stable support structure through the longitudinal frame 21 and the transverse frame 22. Several temperature sensors 210 monitor the temperature data of different areas inside the greenhouse body 2 in real time. Growers can use the temperature information fed back by the sensors, combined with the growth needs of the vegetables, to adjust the ventilation openings, insulation coverings, or supplemental lighting equipment to achieve basic control of the temperature and light inside the greenhouse, ensuring that the vegetables are in a suitable growing environment.

[0027] Example 2: The technical solution of this example, which differs from Example 1, includes: a water storage tank 3 installed on one side of the greenhouse body 2; a water source heat pump temperature regulating unit installed on the outer wall of the water storage tank 3; the water source heat pump temperature regulating unit includes a cooling and heating pump body 31; a controller 32 is installed at the top of the cooling and heating pump body 31; a refrigerant conduit 33 installed inside the greenhouse body 2 is fixedly connected to the output end of the cooling and heating pump body 31; several U-shaped insert frames 4 are inserted on both inner sides of the greenhouse body 2; elastic connecting ropes 41 are fixedly connected between the U-shaped insert frames 4; and the U-shaped insert frames 4 have elastic connecting ropes 41 on both sides. The walls are all provided with inclined grooves 401 that are interference fit with the refrigerant pipes 33, and the temperature sensors 210 are all electrically connected to the controller 32. The refrigerant pipes 33 are distributed in a continuous curved shape at the inner end of the greenhouse body 2, and the transverse frame 22 and the refrigerant pipes 33 are all wrapped with limiting ropes 220. The sections of the refrigerant pipes 33 that penetrate into the ground are all spirally arranged. The water source heat pump type water temperature regulating units and water storage tanks 3 located at both ends of the greenhouse body 2 are all staggered, and the top of the water storage tanks 3 are respectively embedded with water inlet pipes. The tops of several U-shaped inserts 4 are all fixedly connected with handles 42.

[0028] Among them, the water source heat pump type water temperature regulating unit mainly includes a heat pump host (including compressor, condenser, evaporator, four-way reversing valve) to realize the switching between cooling and heating, a water tank heat exchange unit (including coil heat exchanger, insulation layer, liquid level sensor) for water heat exchange and water storage, and a circulation power and control unit (controller 32) to drive water circulation and precise temperature control.

[0029] It can collect temperature data in different areas inside the greenhouse body 2 in real time and transmit the data synchronously to the controller 32, providing the controller 32 with accurate basis for determining whether to start and adjust the water source heat pump water temperature regulating unit, which is the core sensing basis for realizing automatic temperature control.

[0030] The refrigerant conduit 33 is continuously curved and distributed at the inner end of the greenhouse body 2, which can increase the contact area with the air inside the greenhouse and improve the heat exchange efficiency. The limiting rope 220 wrapped around the horizontal frame 22 and the refrigerant conduit 33 can fix the position of the refrigerant conduit 33 and prevent it from shifting due to water flow impact or external force. The section of the refrigerant conduit 33 that penetrates into the ground is set in a spiral shape, which can prolong the flow time and path of the refrigerant water inside the ground and enhance the effect of regulating soil temperature.

[0031] The water source heat pump type water temperature regulating units at both ends of the greenhouse body 2 and the water storage tank 3 are staggered to form a circulating cooling system;

[0032] The handle 42 facilitates the installation and removal of the U-shaped insert frame 4.

[0033] When in use, first inject sufficient water through the water inlet pipe at the top of the water storage tank 3. The whole device operates with the "staggered layout of the two sides of the circulating cooling system" as the core (one end of the water storage tank 3 is full of water, and the other end of the water storage tank 3 is empty and loaded with cooled water) - the staggered water storage tank 3 at both ends of the greenhouse body 2 and the water source heat pump water temperature regulating unit not only avoid the equipment occupying the planting space in a concentrated manner, but also allow the refrigerant pipe 33 to form a more balanced circulation path.

[0034] During operation, first grasp the handle 42 at the top of the U-shaped insert frame 4, and insert the refrigerant conduit 33 segment by segment into the inclined groove 401 on the side wall of the U-shaped insert frame 4 (the inclined groove 401 and the refrigerant conduit 33 are interference-fitted to ensure that the conduit is installed firmly and does not slip). Adjacent U-shaped insert frames 4 are connected by elastic connecting ropes 41 (and the elastic connecting ropes 41 are designed for easy storage). The installation spacing can be flexibly adjusted according to the internal space of the greenhouse body 2. At the same time, the limiting ropes 220 on the transverse frame 22 are used to wrap and fix the refrigerant conduit 33 to further prevent the conduit from shifting during water circulation. After the installation is completed, bury the section of the refrigerant conduit 33 that extends to the ground in a spiral shape into the soil to ensure that the conduit is in full contact with the soil.

[0035] When the system is started, the temperature sensor 210 monitors the temperature of different areas inside the greenhouse body 2 in real time and transmits the data to the controller 32 at the top of the cooling and heating pump body 31. The controller 32 automatically controls the operation of the cooling and heating pump body 31 according to a preset temperature threshold. When heating is needed, the heat pump body heats the water in the water storage tank 3, and the generated hot water circulates along the refrigerant conduit 33. The spiral buried conduit extends the flow time of the hot water in the soil, fully transferring heat to the soil layer, achieving ground insulation, and preventing crop roots from being affected by low temperatures. When cooling is needed, the heat pump body switches to cooling mode, and cold water circulates along the conduit. The spiral structure also extends the cooling effect time, efficiently reducing the ground temperature. At the same time, the continuously curved refrigerant conduit 33 distributed throughout the greenhouse exchanges heat evenly with the air, assisting in regulating the air temperature inside the greenhouse. The entire system, through the precise installation of the refrigerant conduit 33 and the spiral buried design, takes into account both ground temperature control and greenhouse air temperature regulation, providing a stable and suitable growing environment for green vegetables.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
