Description

Technical Field

[0001] This invention relates to the detection of carbon dioxide flow fields, and particularly to the detection of carbon dioxide flow fields at different locations on the same horizontal plane in space and at multiple horizontal planes at different heights, specifically a carbon dioxide flow field detection device. Background Technology

[0002] Currently, the design of carbon dioxide fire extinguishing systems in engineering projects often involves human error. Designers either rely on various standard tables and curves for calculations, leading to errors, or they over-rely on software, resulting in over-reliance on procedural methods and raising questions during project review. This paper provides three methods for calculating the pipe diameter of carbon dioxide fire extinguishing systems: formulaic, graphical, and functional methods. An analytical formula for direct design calculations is established, and the nozzle type is calculated based on the pipe outlet pressure. However, the concentration of carbon dioxide emitted from the nozzles cannot be effectively measured, and the measurement process is fragmented, resulting in significant time wastage and hindering rapid and efficient measurement. Furthermore, the continued use of handheld measuring devices introduces unavoidable human error, leading to inaccurate results. All these factors indicate that there is still considerable room for research in carbon dioxide flow field detection technology. Summary of the Invention

[0003] In view of the above-mentioned technical problems, the present invention provides a carbon dioxide flow field detection device, which aims to solve the problems in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0005] The technical solution adopted by this invention to solve its technical problem includes: four hydraulic lifting columns, a connecting plate, four slide rails, four stepper motors, two tension sensors, two tension ropes, four lead screws, a cross connector, a probe, four couplings, four sliders, and two tensioners. The four sliders are divided into two pairs. Each pair of sliders is equipped with a tension sensor and a tensioner, connected by a tension rope. The two tension ropes are connected by a cross connector, on which a probe is fixed. When carbon dioxide is ejected from the nozzle, the probe moves to different positions as required, experiences force, which is transmitted to the tension rope, then to the tension sensor, and finally outputs the carbon dioxide flow field intensity at that position.

[0006] Furthermore, the probe is connected to two tension ropes via a cross connector, and the probe is fixed to the cross connector via an interference fit. The cross connector is connected to the tension ropes via an overfit.

[0007] Furthermore, the tension sensor is fixed to the slider by two screws.

[0008] Furthermore, the slide rail is fixed to the connecting plate by bolts.

[0009] Furthermore, each tensioner is fixed to the slider by four bolts.

[0010] Furthermore, the four hydraulic lifting columns are fixed to the connecting plate by bolts.

[0011] The purpose of this invention is to overcome the problem that water vapor and other gases in the air condense and affect the detection when measuring carbon dioxide flow field. At the same time, it provides a new carbon dioxide concentration detection device. By combining a hydraulic lifting column and a sliding table, the probe can be moved arbitrarily in space. Combined with a tension sensor and a tensioner, the carbon dioxide flow field can be measured. The device has a simple structure and high stability. Attached Figure Description

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be understood that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] In this invention, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of these terms in this invention according to the specific circumstances.

[0020] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described examples are only some embodiments of the present invention.

[0022] like Figure 1-3 As shown, the embodiment of the present invention includes 1-hydraulic lifting column, 2-connecting plate, 3-slide rail, 4-stepper motor, 5-tension sensor, 6-tensioning rope, 7-lead screw, 8-cross connector, 9-probe, 10-coupling, 11-slider, and 12-tensioner.

[0023] The carbon dioxide flow field detection device has a tension sensor 5 and a tensioner 12 fixed on its slider 11, connected by a tension rope 6. During operation, the slider 11 moves on the slide rail 3, sending the probe 9 to a designated position, and the tension rope 6 is tensioned by the tensioner 12. When carbon dioxide flows from the nozzle (at...) Figure 2 When the carbon dioxide is ejected from above the probe, the probe is subjected to force, which is transmitted to the tension rope 6, then to the tension sensor 5, and finally outputs the carbon dioxide concentration reading at that position.

[0024] Before testing, the height of the lifting platform needs to be adjusted so that the top of the probe reaches the specified height, and then the position of the probe in the plane is adjusted by moving the slide.

[0025] After measuring one location point, when adjusting the position of the hydraulic lifting column and slider to continue measuring the second location point, the tensioning rope needs to be tensioned again using the tensioner.

[0026] The slide should not move too fast, otherwise it will cause severe wear on the tension rope and the cross connector.

[0027] The purpose of this invention is to overcome the shortcomings of current carbon dioxide flow field measurement technology and to provide a new carbon dioxide flow field detection device. By combining a hydraulic lifting column and a sliding table, the carbon dioxide concentration at any point in space can be detected. The device is characterized by simple structure, high accuracy of measurement range, and strong anti-interference ability.
