Description

Technical Field

[0001] This utility model relates to a carbon monoxide and carbon dioxide detection system inside a planting greenhouse. Background Technology

[0002] During colder seasons, greenhouses need to be heated by burning coal, wood, and straw. The combustion of these fuels produces carbon monoxide and carbon dioxide. Carbon monoxide can cause poisoning, and while carbon dioxide helps plants grow, high concentrations can cause fainting in people entering the greenhouse. Therefore, it is necessary to monitor the concentrations of carbon monoxide and carbon dioxide in greenhouses heated by burning fuel to ensure the safety of the workers.

[0003] Currently used intelligent gas detection systems have certain limitations. Firstly, the accuracy of sensors is easily affected by environmental factors. High humidity, high dust levels, and drastic temperature changes in greenhouses can all cause deviations in sensor output signals, resulting in inaccurate detection data and an inability to reflect the true gas concentration in a timely manner. Secondly, the maintenance costs of these devices are high. Not only do they require regular calibration and maintenance by professional technicians, but some high-precision sensors also have limited lifespans, leading to significant replacement costs. Thirdly, while portable gas detectors are convenient, they suffer from limited detection range and short battery life. Failure to charge or calibrate them in a timely manner during use can also lead to inaccurate results. Growers need to carefully consider these drawbacks in practical use to better ensure the safety of greenhouse operations.

[0004] Therefore, existing gas detection equipment used in greenhouses may have problems such as insufficient battery life and inaccurate detection results. Summary of the Invention

A heating rod is installed inside the heating chamber 3, and its heating switch is connected to the detection control platform 1. The water inlet and outlet pipes of the heating chamber 3 are connected to the outside of the dust collector 2D. After the heating chamber 3 is filled with water, the water is heated by the heating rod.

Figure 9 The inner diameter of the conical vent tube 31 shown is for illustrative purposes only. To make the lines clear, only three conical vent tubes 31 are shown. The number of conical vent tubes 31 and the degree of gradation of their inner diameters can be adjusted according to the effect of heating the gas. Specific Implementation Method Two:

[0040] This embodiment of the carbon monoxide and carbon dioxide detection system inside a planting greenhouse differs from specific embodiment one in that, for example... Figure 7As shown, the housing 2B1 is a hollow sheet metal structure with an open front end. The top of housing 2B1 has two rectangular openings, and the inner wall of the side wall of housing 2B1 has guide grooves corresponding to each opening. The coarse filter dust removal plate 2B2 is surrounded by a frame, on which a 50-80 mesh coarse filter screen is installed to block dust. The fine filter dust removal plate 2B3 has the same structure as the coarse filter dust removal plate 2B2, with a 150-200 mesh fine filter screen installed on the frame to block dust. The top of the dust removal plate 2B2 is equipped with a handle; the coarse dust removal plate 2B2 and the fine dust removal plate 2B3 are inserted into the rectangular opening at the top of the housing 2B1 through guide grooves, and the fine dust removal plate 2B3 is inserted into the rectangular opening at the middle position of the top of the housing 2B1; the dust removal reducer pipe 2B4 is a hollow pipe, and the inner diameter of the dust removal reducer pipe 2B4 gradually decreases from the air inlet end to the air outlet end; the hollow reducer pipe 2B4 is fixedly connected to the opening at the rear end of the housing 2B1. Specific implementation method three:

[0042] This embodiment of the carbon monoxide and carbon dioxide detection system inside a planting greenhouse differs from specific embodiments one or two in that, for example... Figure 8 As shown, the dust removal fan 2C includes a centrifugal fan 2C1, a fan variable diameter outlet duct 2C2, a fan outlet duct 2C3, and a fan variable diameter inlet duct 2C4.

[0043] The variable diameter inlet pipe 2C4 is installed at the inlet of the centrifugal fan 2C1, the variable diameter outlet pipe 2C2 is installed at the outlet of the centrifugal fan 2C1, and the outlet pipe 2C3 is installed at the outlet end of the variable diameter outlet pipe 2C2. The gas dust removal device 2 is connected to the detection and control platform 1 through the outlet pipe 2C3. The inner diameter of the variable diameter outlet pipe 2C2 gradually decreases from the inlet end to the outlet end, and the inner diameter of the variable diameter inlet pipe 2C4 gradually decreases from the inlet end to the outlet end.

[0044] like Figure 8-10 As shown, the dust collector 2D includes a tank body 2D1, a dust collector outlet pipe 2D2, and a dust collector inlet pipe 2D3; the dust collector outlet pipe 2D2 and the dust collector inlet pipe 2D3 are installed on the top of the tank body 2D1, and the tank body 2D1 is connected to the dust collector outlet pipe 2D2 and the dust collector inlet pipe 2D3.

[0045] One end of the dust removal outlet pipe 2D2 is connected to the fan reducer inlet pipe 2C4, and the other end is inserted into the top of the tank 2D1 and connected to the tank 2D1; one end of the dust removal inlet pipe 2D3 is connected to the dust removal reducer pipe 2B4, and the other end is inserted into the top of the tank 2D1 and connected to the tank 2D1.

[0046] The horizontal height of the end of the dust removal outlet pipe 2D2 inside the tank 2D1 is higher than the horizontal height of the end of the dust removal inlet pipe 2D3 inside the tank 2D1. That is, when the tank 2D1 is filled with water, the dust removal inlet pipe 2D3 extends below the water surface inside the tank 2D1, while the dust removal outlet pipe 2D2 extends into the tank 2D1 but is located above the water surface. Specific implementation method four:

[0048] This embodiment of the carbon monoxide and carbon dioxide detection system inside a greenhouse differs from specific embodiment three in that, for example... Figure 11 As shown, the detection and control platform 1 includes a control platform housing 1A, control buttons 1B, a touch screen 1C, a carbon monoxide detector 1D, and a carbon dioxide detector 1E.

[0049] The control platform housing 1A serves as the support structure for the detection control platform 1. It is a hollow sheet metal structure. The control button 1B and touch screen 1C are installed at the front of the control platform housing 1A. The carbon monoxide detector 1D and carbon dioxide detector 1E are installed at the top of the detection control platform 1. Pipelines are installed inside the control platform housing 1A, which are connected to the carbon monoxide detector 1D and carbon dioxide detector 1E respectively. The fan outlet pipe 2C3 is connected to the pipelines of the control platform housing 1A, which can deliver gas to the carbon monoxide detector 1D and carbon dioxide detector 1E respectively.

[0050] Working principle:

[0051] Before use, place the gas dust removal device 2 inside the greenhouse and the detection and control platform 1 outside the greenhouse. The two are connected by the fan outlet pipe 2C3. The operator can check the concentration of carbon monoxide and carbon dioxide in the gas inside the greenhouse from the detection and control platform 1 outside the greenhouse.

[0052] After burning combustibles such as coal, straw, and wood in the greenhouse, in order to detect the carbon monoxide and carbon dioxide levels in the greenhouse, the centrifugal fan 2C1 in the dust removal fan 2C is started by the control button 1B on the detection control platform 1, thereby generating negative pressure and drawing the gas in the greenhouse into the housing 2B1 of the dust removal box 2B.

[0053] The gas will pass through the coarse dust removal plate 2B2 and the fine dust removal plate 2B3 in sequence. During the combustion process, larger dust particles will be blocked by the coarse dust removal plate 2B2, and relatively smaller dust particles will be blocked by the fine dust removal plate 2B3. Then the gas will carry the fine dust particles out of the dust removal box 2B through the dust removal reducer pipe 2B4, and then enter the tank 2D1 of the dust removal can 2D through the dust removal inlet pipe 2D3.

[0054] Gas carrying fine dust particles is introduced into the tank 2D1 below the water surface through the dust removal inlet pipe 2D3. The fine dust particles in the gas are removed by water washing. The gas is then heated and pressurized through the conical vent pipe 31 on the hot box 3 to make it evenly mixed. The gas then flows out of tank 2D1 through dust removal outlet pipe 2D2. After dust removal and washing, the gas enters centrifugal fan 2C1 through fan reducer inlet pipe 2C4 via dust removal outlet pipe 2D2. Driven by the fan blades inside centrifugal fan 2C1, the gas flows out through fan reducer outlet pipe 2C2 and fan outlet pipe 2C3, leading to the detection and control platform 1 located outside the greenhouse. Fan outlet pipe 2C3 is connected to the pipeline of control platform box 1A, which can deliver the gas to carbon monoxide detector 1D and carbon dioxide detector 1E respectively. The measured values ​​are displayed on touch screen 1C so that operators can read them and take timely measures according to the actual situation to ensure that planting personnel can enter the greenhouse to work under safe conditions.

[0055] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
