Description

Technical Field

[0001] The utility model relates to the technical field of agricultural greenhouses, in particular to a solar greenhouse with a carbon dioxide gas fertilizer application function. Background Art

[0002] Greenhouses, also known as warm houses, are facilities that can transmit light and keep warm, and are commonly used by modern farmers to grow plants. They are not restricted by seasons, and can grow vegetables, flowers, trees, fruits and other plants that meet market demand in off-seasons, meeting people's living needs. In the agricultural production process in northern China, the temperature varies greatly throughout the year. In order to achieve high yields and high yields of crops throughout the year, greenhouses usually use a large amount of fertilization and spraying of pesticides to increase production. There are problems such as large amount of fertilization, poor timeliness, and poor environmental protection.

[0003] Plant growth depends on photosynthesis, and the occurrence of photosynthesis must be involved in carbon dioxide gas, that is, carbon dioxide can be used as a gas fertilizer for greenhouse planting. Therefore, in the prior art, some greenhouses have begun to implement gas fertilization by adding carbon dioxide to the inside of the greenhouse to increase the yield of crops in the greenhouse. However, when applying carbon dioxide gas fertilizer to the greenhouse, carbon dioxide is usually added to the greenhouse by manually controlling the carbon dioxide generator. The carbon dioxide content in the greenhouse is different at different times and in different climates, and the requirements for the amount of carbon dioxide are different for different crops planted. The method of manually applying carbon dioxide to the greenhouse is difficult to ensure that the amount of carbon dioxide gas fertilizer applied can meet the requirements of the plants planted, while avoiding excessive application of carbon dioxide gas fertilizer, resulting in a waste of electrical energy. Therefore, the accuracy of the current carbon dioxide gas fertilizer application scheme is poor. Utility Model Content

[0004] In view of this, in order to address the above shortcomings, it is necessary to propose a solar greenhouse with the function of applying carbon dioxide gas fertilizer to achieve precise fertilization of crops in the solar greenhouse, so as to ensure the crops' demand for carbon dioxide gas fertilizer while avoiding excessive electrical energy loss.

[0005] The utility model provides a solar greenhouse with a carbon dioxide gas fertilizer application function, comprising: a greenhouse body, a carbon dioxide generator, a carbon dioxide concentration detection device, a light intensity detection device, a carbon dioxide diffusion device and a main control device; wherein the main control device is electrically connected to the carbon dioxide generator, the carbon dioxide concentration detection device, the light intensity detection device and the carbon dioxide diffusion device respectively;

[0006] The carbon dioxide concentration detection device and the light intensity detection device are both arranged inside the greenhouse body, and are used to respectively detect the carbon dioxide content information and light intensity information inside the greenhouse body in real time, and send the detected carbon dioxide content information and light intensity information to the main control device; the carbon dioxide generator and the carbon dioxide diffusion device are both arranged inside the greenhouse body, and the carbon dioxide outlet is connected to the carbon dioxide diffusion device through a pipeline, the carbon dioxide generator is used to generate carbon dioxide, and the carbon dioxide diffusion device is used to diffuse the generated carbon dioxide to various positions in the greenhouse body; the main control device is used to control the operation of the carbon dioxide generator and the carbon dioxide diffusion device according to the received carbon dioxide content information and light intensity information.

[0007] Preferably, a water tank is further provided in the solar greenhouse, and the water inlet of the carbon dioxide generator is connected to the water tank through a pipeline, so as to extract water in the water tank to provide the carbon dioxide generator with water required for its operation.

[0008] Preferably, an ammonia water collecting tank is also provided in the solar greenhouse, and the drain outlet of the carbon dioxide generator is connected to the ammonia water collecting tank through a pipeline, so as to discharge the ammonia water generated by the carbon dioxide generator into the ammonia water collecting tank for storage.

[0009] Preferably, the carbon dioxide generator is provided with an emergency exhaust port, which is connected to the outside of the greenhouse body through a pipeline, so as to discharge the ammonia generated by the carbon dioxide generator to the outside of the greenhouse body in an emergency.

[0010] Preferably, the carbon dioxide diffusion devices include a plurality of carbon dioxide diffusion devices, each of which is evenly distributed inside the greenhouse body.

[0011] Preferably, the carbon dioxide diffusion device is an axial flow fan, and each axial flow fan is evenly distributed and suspended on a steel beam above the greenhouse body.

[0012] Preferably, the hanging angle of each axial flow fan is adjustable so that the blowing direction of the axial flow fan can be adjusted between a direction facing the ground and a direction facing the wall.

[0013] Preferably, the solar greenhouse further comprises a remote control terminal, which is communicatively connected to the main control device and is used for receiving the execution status of each device in real time and controlling the operation of each device.

[0014] It can be seen from the above technical scheme that the solar greenhouse with the function of applying carbon dioxide gas fertilizer provided by the embodiment of the utility model includes a greenhouse body, a carbon dioxide generator, a carbon dioxide concentration detection device, a light intensity detection device, a carbon dioxide diffusion device and a main control device. The carbon dioxide concentration detection device and the light intensity detection device can detect the carbon dioxide content information and light intensity information in the greenhouse body, and send the detected carbon dioxide content information and light intensity information to the main control device. The main control device determines whether the application of carbon dioxide gas fertilizer is needed in the current greenhouse body according to the received carbon dioxide content information and light intensity information. If the application of carbon dioxide gas fertilizer is needed, the carbon dioxide generator and the carbon dioxide diffusion device are controlled to work, so that the carbon dioxide generator produces carbon dioxide, and diffuses it into the greenhouse body through the carbon dioxide diffusion device, so as to realize the application of carbon dioxide gas fertilizer in the greenhouse body. It can be seen that the application of carbon dioxide gas fertilizer in the solar greenhouse in this scheme is based on the real-time detection of the concentration and light intensity information of carbon dioxide in the greenhouse, thereby ensuring that the carbon dioxide content in the greenhouse can meet the photosynthesis requirements of crops, and at the same time, it will not cause more power loss due to excessive production of carbon dioxide, thereby realizing the precise application of carbon dioxide gas fertilizer to crops in the solar greenhouse.

DETAILED DESCRIPTION

[0018] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0019] See also Figure 1-2The embodiment of the utility model provides a solar greenhouse with a carbon dioxide gas fertilizer application function, comprising: a greenhouse body 10, a carbon dioxide generator 20, a carbon dioxide concentration detection device, a light intensity detection device, a carbon dioxide diffusion device 30 and a main control device; wherein the main control device is electrically connected to the carbon dioxide generator 20, the carbon dioxide concentration detection device, the light intensity detection device and the carbon dioxide diffusion device 30 respectively;

[0020] The carbon dioxide concentration detection device and the light intensity detection device are both arranged inside the greenhouse body 10, and are used to respectively detect the carbon dioxide content information and light intensity information inside the greenhouse body 10 in real time, and send the detected carbon dioxide content information and light intensity information to the main control device; the carbon dioxide generator 20 and the carbon dioxide diffusion device 30 are both arranged inside the greenhouse body 10, and the carbon dioxide outlet 21 is connected to the carbon dioxide diffusion device 30 through a pipeline, the carbon dioxide generator 20 is used to generate carbon dioxide, and the carbon dioxide diffusion device 30 is used to diffuse the generated carbon dioxide to various positions in the greenhouse body 10; the main control device is used to control the operation of the carbon dioxide generator 20 and the carbon dioxide diffusion device 30 according to the received carbon dioxide content information and light intensity information.

[0021] In this embodiment, the carbon dioxide concentration detection device and the light intensity detection device can detect the carbon dioxide content information and light intensity information in the greenhouse body 10, and send the detected carbon dioxide content information and light intensity information to the main control device. After receiving the carbon dioxide content information and light intensity information, the main control device combines the pre-set crop type, the carbon dioxide content required by the crop in the current time period and other information to determine whether the carbon dioxide content in the current solar greenhouse can meet the photosynthesis of the crop. If it can, the main control device does not respond, and the carbon dioxide concentration detection device and the light intensity detection device continue to monitor. If the current carbon dioxide content in the solar greenhouse cannot meet the photosynthesis of the crop, the carbon dioxide generator 20 and the carbon dioxide diffusion device 30 are controlled to work, so that the carbon dioxide generator 20 generates carbon dioxide, and diffuses it into the greenhouse body 10 through the carbon dioxide diffusion device 30, increasing the carbon dioxide content in the greenhouse body 10 to meet the carbon dioxide demand of the crop in the current solar greenhouse when photosynthesis. In this way, the carbon dioxide content in the greenhouse body 10 is adjusted in real time according to the detection results, ensuring that the carbon dioxide content in the greenhouse body 10 is sufficient for the photosynthesis of the current crop, while avoiding the carbon dioxide generator 20 and the carbon dioxide diffusion device 30 from continuously working to produce excessive carbon dioxide, causing loss of electrical energy. Therefore, this solution can achieve scientific and accurate fertilization of crops.

[0022] For the carbon dioxide generator 20, consider using Huanqing ZFC-30 carbon dioxide generator 20, and consider using ammonium bicarbonate as raw material, with a carbon dioxide output ratio of 1:0.55. The chemical process of heating and decomposing ammonium bicarbonate: (NH4HCO3=NH3+H2O+CO2) to generate carbon dioxide. When ammonium bicarbonate is heated to about 60°C, it decomposes into NH3 (21.5%), CO2 (55.7%), H2O (22.8%), and then the generated carbon dioxide is transported to various locations in the greenhouse body 10 through the carbon dioxide diffusion device 30. At the same time, the carbon dioxide concentration detection device monitors the carbon dioxide concentration in the greenhouse body 10 in real time, and uses a fuzzy algorithm to stop working when the carbon dioxide concentration is about to reach the critical value, so that the carbon dioxide concentration is maintained at the optimal concentration required for plant photosynthesis, improve photosynthesis efficiency, and improve yield and quality.

[0023] The main advantage of using ammonium bicarbonate to generate carbon dioxide by heating and decomposing is that it is stable and controllable. There is no need to place traditional carbon dioxide generating devices at multiple points in the greenhouse, nor is there a need to replace gas cylinders. It is simple to use and avoids safety accidents. Only one device needs to be fixed in the greenhouse. At the same time, the carbon dioxide diffusion device 30 is used for relay transmission, so that the carbon dioxide concentration in the greenhouse is more uniform and the fertilization effect is good.

[0024] The carbon dioxide generator 20 may include a carbon dioxide outlet 21, a water injection port 22, a water outlet 23, and an emergency exhaust port 24. The carbon dioxide outlet 21 is connected to the carbon dioxide diffusion device 30 to discharge the high-concentration carbon dioxide generated by the carbon dioxide generator 20 and diffuse it into the greenhouse body 10 through the carbon dioxide diffusion device 30.

[0025] The water injection port 22 is mainly used to inject water into the carbon dioxide generator 20. In one embodiment, it can be considered to be provided with a water tank 40 in the greenhouse body 10, and the water tank 40 can be a water tank 40 for replenishing water for crops. The water injection port 22 of the carbon dioxide generator 20 is connected to the water tank 40 through a pipeline, and is used to extract water in the water tank 40 to provide the carbon dioxide generator 20 with water required for operation. Of course, the water injection port 22 of the carbon dioxide generator 20 can also be directly connected to tap water, and tap water can be directly injected when water injection is required.

[0026] The drain port 23 is mainly used to discharge the low-concentration ammonia water produced by the carbon dioxide generator 20. In one embodiment, it is considered to set an ammonia water collection tank 50 in the greenhouse body 10, and the drain port 23 of the carbon dioxide generator 20 is connected to the ammonia water collection tank 50 through a pipeline, so as to discharge the ammonia water produced by the carbon dioxide generator 20 into the ammonia water collection tank 50 for storage. In this way, the collected ammonia water can be used as nitrogen fertilizer for fertilizing crops after subsequent treatment.

[0027] The emergency exhaust port 24 is mainly used to discharge ammonia in an emergency. In one embodiment, the carbon dioxide generator 20 is also provided with an emergency exhaust port 24, which is connected to the outside of the greenhouse body 10 through a pipeline, so as to discharge the ammonia generated by the carbon dioxide generator 20 to the outside of the greenhouse body 10 in an emergency. For example, in the event of a sudden power outage or equipment failure, the unpurified gas is directly discharged to the outside of the solar greenhouse through the emergency exhaust port 24 and the corresponding pipeline to avoid damage to the crops in the solar greenhouse.

[0028] Of course, it should be pointed out that solenoid valves should be installed on the pipelines connecting the carbon dioxide outlet 21, the water inlet 22, the drain outlet 23 and the emergency exhaust outlet 24, and each solenoid valve is electrically connected to the main control device so that its opening and closing can be controlled by the main control device.

[0029] In one embodiment, the carbon dioxide diffusion devices 30 include a plurality of carbon dioxide diffusion devices 30, and each carbon dioxide diffusion device 30 is evenly distributed inside the greenhouse body 10. In this way, it can be ensured that carbon dioxide can be evenly distributed at various positions of the greenhouse body 10.

[0030] In one embodiment, the carbon dioxide diffusion device 30 can be an axial flow fan, and each axial flow fan is evenly distributed and suspended on a steel beam above the greenhouse body 10. It is electrically connected to the main control device so that its operation is controlled by the main control device.

[0031] In addition, in one embodiment, the hanging angle of each axial flow fan is adjustable so that the blowing direction of the axial flow fan can be adjusted between facing the ground and facing the wall. In this way, by adjusting the blowing angle of the axial flow fan, carbon dioxide can be quickly diffused to various positions in the greenhouse body 10, thereby accelerating the efficiency and uniformity of carbon dioxide diffusion.

[0032] In one embodiment, in order to facilitate remote control by operators, the solar greenhouse may also include a remote control terminal, such as a mobile phone, tablet, computer, etc. The remote control terminal is connected to the main control device for real-time reception of the execution status of each device and control of the operation of each device. In this way, the staff can view the working status of each device in the solar greenhouse through the remote control terminal, and can also issue instructions through the remote control terminal to turn on or off each device.

[0033] The modules or units in the device of the embodiment of the utility model can be combined, divided and deleted according to actual needs. The above disclosure is only the preferred embodiment of the utility model, and of course it cannot be used to limit the scope of the rights of the utility model. Ordinary technicians in this field can understand that all or part of the processes of the above embodiments are implemented, and equivalent changes made according to the claims of the utility model still fall within the scope of the utility model.
