Description

Technical Field

[0001] This utility model belongs to the field of agricultural greenhouse technology, specifically a temperature control system for growing sprouts in a greenhouse. Background Technology

[0002] Sprouts, also known as sprouts, are vegetables that are grown from the tender shoots, seedlings, or stems of plant seeds or other nutrient storage organs under suitable environmental conditions, and are consumed as the edible part. Because sprouts are relatively short, they are generally short when grown in greenhouses. Most existing greenhouse temperature control systems are located at the top of the greenhouse, and since hot air tends to rise, the temperature control effect at the bottom is poor. Furthermore, most of the heat sources in greenhouse temperature control systems are located inside the greenhouse. While this setup has a high heat utilization rate, it leads to uneven temperature distribution within the greenhouse. Plants near the heat source may die from overheating, while plants farther away will grow slowly due to lower temperatures. Additionally, because the edible part of sprouts is their tender shoots or seedlings, their growth period is very short, requiring precise temperature control. Utility Model Content

[0003] To address the above technical problems, this utility model provides a temperature control system for greenhouse sprout cultivation.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is as follows: a temperature control system for growing sprouts in a greenhouse, including a greenhouse, an ear chamber connected to the side of the greenhouse, a heat storage box installed in the ear chamber, a venting pipe connected to the heat storage box, the venting pipe being located inside the greenhouse and below the wall of the greenhouse, an air pump installed at the first end of the venting pipe, and an air conditioning system, wherein the indoor unit of the air conditioning system is located inside the ear chamber and the outdoor unit of the air conditioning system is located outside the ear chamber, the air outlet of the indoor unit of the air conditioning system is connected to the heat storage box, a humidifier is installed in the ear chamber, the air outlet of the humidifier is connected to the heat storage box, several air outlet pipes are connected to the venting pipe, and plastic tubes are sleeved on the air outlet pipes, a temperature and humidity monitor is fixedly installed inside the greenhouse, a controller is installed in the ear chamber, the temperature and humidity monitor is electrically connected to the controller, and the air conditioning system, air pump, and humidifier are all controlled by the controller.

[0005] Furthermore, an electric heating rod is fixedly connected inside the temperature storage tank, and the electric heating rod is controlled by the controller.

[0006] Furthermore, a pressure relief pipe is connected to the heat storage tank.

[0007] Furthermore, a solenoid valve is installed on the pressure relief pipe.

[0008] Furthermore, the outside of the heat storage box is wrapped with an insulation layer.

[0009] Furthermore, the temperature storage tank is equipped with a temperature detector, which is communicatively connected to the controller.

[0010] This utility model has the following advantages compared with the prior art:

[0011] This invention features a downward-facing, wall-mounted ventilation pipe with a plastic tube fitted over its outlet. This allows for the direct delivery of gas at a suitable temperature to the vicinity of the sprouts, resulting in a uniform and rapid temperature increase that better meets the growth requirements of the sprouts. An air conditioning system is included to raise the temperature in cold weather and lower it in hot weather. A humidifier is also included to increase humidity within the greenhouse, promoting sprout growth. Furthermore, the combination of the ventilation pipe and the plastic tube facilitates installation and disassembly, reducing operating costs and making it more suitable for the short growth cycle of sprouts.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1-3 The temperature control system for growing sprouts in a greenhouse includes a greenhouse 1, with a side chamber 2 connected to the side of the greenhouse 1. A heat storage box 3 is installed in the side chamber 2, and the heat storage box 3 is connected to a ventilation pipe 5. The ventilation pipe 5 is located inside the greenhouse 1 and below the wall of the greenhouse 1. An air pump 4 is installed at the first end of the ventilation pipe 5. The system also includes an air conditioning system, with an indoor air conditioning unit 7 located inside the side chamber 2 and an outdoor air conditioning unit 8 located outside the side chamber 2. The air outlet of the indoor air conditioning unit 7 is connected to the heat storage box 3. A humidifier 9 is installed in the side chamber 2, and the air outlet of the humidifier 9 is connected to the heat storage box 3. Several air outlet pipes 6 are connected to the ventilation pipe 5, and plastic tubes 13 are fitted on the air outlet pipes 6. A temperature and humidity monitor 11 is fixedly installed inside the greenhouse 1, and a controller 10 is installed in the side chamber 2. The temperature and humidity monitor 11 is electrically connected to the controller 10. The air conditioning system, the air pump 4, and the humidifier 9 are all controlled by the controller 10.

[0018] It should be noted that in this embodiment, a valve is provided on the pipe connecting the indoor unit 7 of the air conditioner and the heat storage box 3, and a valve is also connected to the air outlet of the humidifier 9.

[0019] The plastic pipe 13 and the air outlet pipe 6 are fastened together using a hose clamp.

[0020] The plastic tube 13 has several air holes evenly distributed on it.

[0021] In order to increase heat when the temperature is low, an electric heating rod 12 is fixedly connected inside the heat storage box 3, and the electric heating rod 12 is controlled by the controller 10.

[0022] To prevent the pressure from being too low, a pressure relief pipe 14 is connected to the heat storage tank 3.

[0023] In order to close the pressure relief pipe 14 in a timely manner, a solenoid valve is installed on the pressure relief pipe 14.

[0024] To reduce heat waste, the outside of the heat storage box 3 is wrapped with an insulation layer 15.

[0025] To prevent overheating, a temperature detector is installed inside the temperature storage box 3, and the temperature detector is connected to the controller 10.

[0026] The specific working process of this utility model is as follows:

[0027] During operation, the temperature and humidity monitor 11 detects the temperature inside the greenhouse 1. When the temperature is low, the controller 10 turns on the air conditioning system, and the indoor unit 7 blows hot air into the storage tank 3. The air pump drives the hot air in the storage tank 3 to blow it onto the diffuser 5, and then onto the sprouts through the plastic tube 13, so that the temperature changes evenly. During heating, the temperature detector in the storage tank 3 can prevent the temperature from getting too high. If it gets too high, the controller stops the air pump 4. When the temperature is high, the air conditioning system generates cold air, and the cold air is blown onto the sprouts in the same way. When the temperature inside the greenhouse 1 is low and affects the development of the sprouts, the humidifier 9 is turned on to blow more humid air into the storage tank 3, and then onto the sprouts through the plastic tube. When the outside temperature is too low and the air conditioning system cannot function, the electric heating rod 12 is turned on for heating. During this process, the pressure relief pipe 14 can be opened to release pressure.

[0028] During the above process, the insulation layer 15 prevents heat loss.

[0029] It should be noted that in this embodiment, the air conditioning system is an industrial air conditioner, the humidifier 9 is an industrial humidifier, and the electric heating rod is an insulated heating rod.
