Description

Technical Field

[0001] This utility model relates to the field of rice cultivation equipment, and in particular to a rice cold resistance identification device. Background Technology

[0002] Rice is one of my country's most important food crops. Low temperatures, especially during the booting stage, can severely impact rice production, directly affecting national food security. Therefore, breeders need to assess the cold tolerance of rice varieties. Currently, the main methods used are artificial climate chambers and 17°C cold water flood irrigation. However, artificial climate chambers have high construction and operating costs, and the amount of material processed at one time is limited, making them unaffordable for most small and medium-sized breeding units and individuals. 17°C cold water flood irrigation is more commonly used, but it requires the construction of mixing tanks and other facilities, necessitating civil engineering and approval procedures. Furthermore, the inconsistent growth point heights between different varieties can lead to significant errors. This method also consumes a large amount of water, resulting in substantial waste. Additionally, once established, the equipment cannot be moved.

[0003] Although artificial climate chambers and cold water flooding are effective methods for assessing cold tolerance in rice during the booting stage, their high operating costs and water waste are significant drawbacks. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a rice cold resistance assessment device. The purpose of this device is to design a rice cold resistance assessment device that is easy to construct, automatically controlled, and uses less water.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rice cold tolerance assessment device includes a cold water tank for storing cold water, a water storage tank for storing room temperature water, a mixing tank, a first water pump, a second water pump, and a micro-spraying belt. The input end of the first water pump is connected to the water storage tank and the cold water tank respectively through a three-way pipe. The output end of the first water pump is connected to the mixing tank. The input end of the second water pump is connected to the mixing tank. The output end of the second water pump is connected to the micro-spraying belt through a pipe. The micro-spray tape is installed at the rice cold resistance assessment site and is used to spray low-temperature water into the environment of the rice cold resistance assessment site.

[0006] Preferably, the branch pipes connecting the cold water tank and the water storage tank in the three-way pipeline are respectively equipped with a first solenoid valve and a second solenoid valve, and the rice cold resistance identification device further includes: A temperature sensor is installed at the rice cold resistance assessment site to acquire the ambient temperature of the site and generate a temperature signal. The controller is connected to the temperature sensor, the first solenoid valve, and the second solenoid valve respectively. The controller is used to receive temperature signals and generate valve opening adjustment commands through the temperature signals. The controller is also used to issue valve opening adjustment commands to the first solenoid valve and the second solenoid valve respectively to adjust the ratio of room temperature water and cold water drawn into the first water pump from the water storage tank and the cold water tank.

[0007] Preferably, there are multiple temperature sensors, which are used to detect and obtain the average ambient temperature of the rice cold resistance assessment site.

[0008] Preferably, both the first and second water pumps are submersible pumps, and both are installed in the mixing tank.

The input end of the return water pump is connected to the water collection tank, and the output end of the return water pump is connected to the water storage tank through a pipeline.

[0013] The beneficial effects of using this utility model are: This device obtains cold water from a mixing tank and combines it with ambient temperature water to form low-temperature water.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0018] This embodiment proposes a rice cold resistance identification device, which is used to solve the problems of high construction difficulty, high water consumption and high equipment cost in the prior art.

[0019] like Figure 1 As shown, this device specifically includes three tanks: a mixing tank 1, a cold water tank 2, and a storage tank 3. The mixing tank 1 uses above-ground equipment and is used to mix water from various sources, including low-temperature water and ambient-temperature water, to reach a predetermined temperature. The cold water tank 2 provides low-temperature water, which can be supplied by natural low-temperature water sources, such as groundwater from wells, with a year-round temperature of around 8℃-10℃. This method is inexpensive, requiring no specialized refrigeration equipment, making the cost of using cold water very low. The storage tank 3 stores ambient-temperature water, also using above-ground equipment, sourced from general surface water.

[0020] In the electrical equipment section, this device mainly includes a first water pump 6 and a second water pump 7. In the supply section of the mixing tank 1, the first water pump 6 is used to connect the mixing tank 1, the cold water tank 2 and the storage tank 3 through pipelines. That is, the input end of the first water pump 6 is connected to the storage tank 3 and the cold water tank 2 through a three-way pipeline, and the output end of the first water pump 6 is connected to the mixing tank 1. After the first water pump 6 is powered on, it can pump the cold water in the cold water tank 2 and the room temperature water in the storage tank 3 into the mixing tank 1 through the pipeline. The cold water and the room temperature water are mixed in the mixing tank 1 to form low temperature water.

[0021] In this embodiment, the advantage of using a three-way pipe is that only one first water pump 6 is needed, which is cheaper than setting up water pump equipment for the cold water tank 2 and the water storage tank 3 respectively.

[0022] A second water pump 7 is used at the output of the mixing tank 1. The input end of the second water pump 7 is connected to the mixing tank 1, and the output end of the second water pump 7 is connected to the micro-spray belt 8 through a pipeline. The second water pump 7 outputs the low-temperature water in the mixing tank 1 to the micro-spray belt 8 through the pipeline. First, the micro-spray belt 8 is filled with water. After the micro-spray belt 8 is filled with water and expands, water is continuously supplied to the micro-spray belt 8 and water pressure is provided to the micro-spray belt 8, so that the low-temperature water inside the micro-spray belt 8 is sprayed into the environment to reduce the ambient temperature of the site and increase the humidity of the site air.

[0023] The above structure is the basic structure of the rice cold resistance identification device. Its effect is to cool the site by mixing natural cold water and room temperature water to form low temperature water, and then spraying the low temperature water evenly into the air through the micro-spray belt 8.

[0024] To regulate the water temperature in mixing tank 1, this device employs a controllable flow regulation system to alter the water supply ratio between cold water tank 2 and storage tank 3. In some feasible embodiments, valves can be installed on the water supply pipelines of cold water tank 2 and storage tank 3. By adjusting the valve opening, the water supply ratio between cold water tank 2 and storage tank 3 can be changed, thereby altering the water temperature in storage tank 3 and ultimately achieving the effect of adjusting the spray water temperature under different site temperature conditions.

[0025] In this embodiment, to further achieve the effect of equipment electrical control, a first solenoid valve 4 and a second solenoid valve 5 are respectively installed on the branch pipes connecting the cold water tank 2 and the water storage tank 3 in the three-way pipeline, and a temperature sensor 13 is installed in the rice cold resistance assessment site to obtain the ambient temperature of the rice cold resistance assessment site and generate a temperature signal; the controller 12 is signal connected to the temperature sensor 13, the first solenoid valve 4 and the second solenoid valve 5 respectively, the controller 12 is used to receive the temperature signal and generate valve opening adjustment command through the temperature signal, and the controller 12 is used to issue valve opening adjustment command to the first solenoid valve 4 and the second solenoid valve 5 respectively to adjust the ratio of room temperature water and cold water drawn into the first water pump 6 from the water storage tank 3 and the cold water tank 2.

[0026] Combination Figure 2 As shown, in this embodiment, the controller 12 is also signal-connected to the first water pump 6 and the second water pump 7 respectively, and the controller 12 can control the on / off state of the first water pump 6 and the second water pump 7. Since in this embodiment, the first water pump 6 and the second water pump 7 are both installed in the mixing tank 1, the first water pump 6 and the second water pump 7 can be connected to the controller 12 respectively by wired connection.

[0027] Therefore, this equipment forms an automatic control device. The core of the automatic control is the PLC controller 12. The automatic control, through a preset control strategy and by detecting the ambient temperature, automatically adjusts the opening of the first solenoid valve 4 and the second solenoid valve 5, ultimately regulating the ratio of cold water to room temperature water entering the water storage tank 3. The controller 12 can be connected to the first solenoid valve 4, the second solenoid valve 5, and multiple temperature sensors 13 via wired or short-range wireless connections, such as Bluetooth or ZigBee. These connection methods have the advantages of low cost and stable connection.

[0028] In some feasible embodiments, there are multiple temperature sensors 13 arranged in an array. Multiple temperature sensors 13 can collect temperature data at multiple points in the site. When the temperature data is transmitted back to the controller 12, the controller 12 processes the multi-point temperature data through a preset processing method, such as calculating the average value of the multi-point temperature data as the basis for forming a control signal, which improves accuracy.

[0029] In this embodiment, preferably, the micro-spray belt 8 is supported at a predetermined height by multiple supports 9, such as 20-30 cm above the rice plants. This way of setting up the micro-spray belt 8 allows the low-temperature water sprayed from the micro-spray belt 8 to travel a longer distance to the ground and cover a larger area, which can allow the low-temperature water and the ambient air to exchange heat fully and achieve the effect of efficiently cooling the site temperature.

[0030] To conserve water resources, in this embodiment, a water collection trough 10 is laid below the rice cold resistance assessment site, and a mesh board is laid on top of the water collection trough 10. The water sprayed by the micro-spray belt 8 falls into the water collection trough 10 after heat exchange. A return water pump 11 is installed in the water collection trough 10, and the output end of the return water pump 11 is connected to the water storage tank 3 through a pipeline. The water in the water collection trough 10 is pumped into the water storage tank 3 by the return water pump 11 for recycling.

[0031] In addition, the water storage tank 3 is equipped with an overflow device. When there is too much water in the water storage tank 3, the overflow portion can be discharged and properly disposed of.

[0032] To facilitate the relocation of this equipment to multiple sites, the mixing tank 1, water storage tank 3, water pipes and solenoid valves, first water pump 6, second water pump 7, micro-spray belt 8, support frame 9, water collection tank 10, return water pump 11, controller 12, and temperature sensor 13 can all be loaded onto vehicles for easy transport.

[0033] A stirring device can also be added to the water storage tank 3 to fully mix cold water and room temperature water.

[0034] Example 1

[0035] When the device starts working, the first solenoid valve 4 and the second solenoid valve 5 are opened by the control system, using cold water from the cold water tank 2 (which contains well water, typically at a temperature of 8°C) to rapidly lower the air temperature in the identification area to 15°C. When the temperature sensor 3 detects an ambient temperature of 12-15°C, the second solenoid valve 5 is opened while the first solenoid valve 4 is partially closed. When the temperature probe 12 reaches 17°C, the first solenoid valve 4 and the second solenoid valve 5 remain in their current states. As the air temperature gradually increases from morning to noon, the temperature sensor 13 detects the temperature increase and adjusts the opening of the first solenoid valve 4 to increase the input of cold water, further reducing the air temperature in the identification area. During operation, the water pressure in the mixing tank 1 mixes the two temperatures of water to achieve the desired target temperature, ensuring accurate spatial temperature control for cold tolerance identification during the rice booting stage.
