Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of gas detection, and in particular to a water-gas separation detection structure. Background Art
[0002] As the fast and efficient pump-type gas detectors are widely recognized by the market, they have become the mainstream gas detection products in the market. The application areas of gas detectors with accessories such as gas pipes have also been greatly expanded, such as invisible oil drums, rivers and waterways, and narrow environments where the instrument cannot be placed for detection.
[0003] For these complex and unknown detection conditions, improper operation will cause damage to the instrument. For example, if there is liquid material such as water in an unknown environment, the pump-suction gas path will draw the liquid material into the sensor detection device, causing damage to the instrument. This brings great inconvenience to the operators. In order to circumvent this problem, various complex configurations are added, which indirectly increases the requirements for the operation threshold, and at the same time brings many troubles and inconveniences to on-site operations.
[0004] The way to deal with similar problems on the market is to add filters and stuff cotton or absorbent filter materials into the filters to slow down and prolong the impact on the gas detection instrument. However, this does not effectively protect the gas detector and requires operators to concentrate. At the same time, the gas detection response time is relatively longer after stuffing cotton or absorbent materials, the detection efficiency is relatively low, and it cannot be recycled.
[0005] Therefore, the prior art has defects and needs to be improved. Summary of the invention
[0006] The main purpose of the present invention is to propose a water-gas separation detection structure, aiming to achieve effective separation of water and gas and protect gas detection instruments.
[0007] To achieve the above-mentioned purpose, the present invention proposes a water-gas separation detection structure, which is installed at the air inlet end of the gas detector, including a float, a plurality of air inlet holes are opened on the surface of the float, and the plurality of air inlet holes are interconnected, and the interior of the float is divided into a plurality of closed cavities by the air inlet holes, one of which is connected to the air inlet end of the gas detector through an air pipe; the number of the air inlet holes is set to 3 to 14, and the arc length between two adjacent air inlet holes is 0.785R to 3.14R, where R is the radius of the float.
[0008] Preferably, the float is configured as a spherical structure made of plastic.
[0009] Preferably, the float is a spherical structure made of PE, PET, PVC, PP, PC, POM or ABS material.
[0010] Preferably, the float is configured as a spherical structure made by blow molding, 3D printing, or injection molding and hot melt.
[0011] Preferably, the number of the air inlet holes is set to six, and the six air inlet holes are evenly divided into three groups, and any group of air inlet holes is located at both ends of the diameter of the float, and the connecting lines between the three groups of air inlet holes are perpendicular to each other.
[0012] Preferably, any three adjacent air inlet holes form an equilateral triangle, the six air inlet holes form eight equilateral triangles, and an additional air inlet hole is provided at the center of each of the eight equilateral triangles.
[0013] Preferably, a filtering and drying device is further provided between the float and the gas detector, and the filtering and drying device comprises a shell, and the interior of the shell is filled with nano absorbent sponge.
[0014] Compared with the prior art, the beneficial effects of the present invention are: when the environment of the gas to be detected is an unknown environment, the water conditions are deep or shallow, or there are wind and waves, the end with the float can be directly thrown into the water surface, the float floats on the water surface, and it is ensured that there is an air inlet leaking out of the water surface. Since the density of air is much smaller than the density of water, the gas on the water surface can be quickly extracted by controlling the suction force, and water and gas separation can be achieved efficiently, preventing water from being drawn into the gas detector and affecting the detection results. The gas detector is well protected and the operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] This embodiment proposes a water-gas separation detection structure, referring to Figure 1 and Figure 2 The water-gas separation detection structure is installed at the air inlet end of the gas detector (not shown in the figure), including a float 1, a plurality of air inlet holes 2 are opened on the surface of the float 1, and the plurality of air inlet holes 2 are interconnected, and the interior of the float 1 is divided into a plurality of closed cavities 3 by the air inlet holes 2, wherein one of the air inlet holes 2 is connected to the air inlet end of the gas detector through an air pipe 4; the number of the air inlet holes 2 is set to 3 to 14, and the arc length between two adjacent air inlet holes 2 is 0.785R to 3.14R, wherein R is the radius of the float 1.
[0022] It should be noted that the present embodiment improves the air intake method of the traditional gas detector, and samples the detection gas through the float 1 structure; when the environment of the gas to be detected is an unknown environment, the water conditions are deep or shallow, or there are wind and waves, the end with the float 1 can be directly thrown to the water surface, the float 1 floats on the water surface, and ensures that there is an air inlet 2 leaking out of the water surface. Since the density of air is much smaller than the density of water, by controlling the suction force of the gas detector air pump, the gas on the water surface can be quickly extracted, and water and gas separation can be efficiently achieved to prevent water from being drawn into the gas detector and affecting the detection results. The gas detector is well protected and the operation is simple and convenient.
[0023] Furthermore, the float 1 is set to a spherical structure made of plastic to ensure that the buoyancy of the float 1 falling into the water surface is large enough, so as to facilitate the detection of gas inhalation. Specifically, the float 1 in this embodiment is set to a spherical structure made of PE or PET or PVC or PP or PC or POM or ABS material.
[0024] Furthermore, the float 1 is configured as a spherical structure made by blow molding, 3D printing, or injection molding and hot melt. These processing methods are commonly used processing methods in the prior art, and a suitable processing method can be selected according to actual production needs and cost requirements.
[0025] Furthermore, a filtering and drying device 5 is additionally provided between the float 1 and the gas detector. The filtering and drying device 5 comprises a shell 51, and the interior of the shell 51 is filled with a nano water-absorbing sponge 52. The detection gas sucked in by the float 1 is further dried, and the water vapor in the detection gas is adsorbed by the nano water-absorbing sponge 52, so as to further improve the dryness of the detection gas, improve the detection accuracy, and further improve the protection of the gas detector.
[0026] Furthermore, it should be noted that the fewer the number of air inlets 2, the larger the proportion of the enclosed cavity 3 inside the float 1, the more air there is inside, and the easier it is for the float 1 to float on the water surface. In this embodiment, after setting different numbers of air inlets 2 for experiments, it was found that when the number of air inlets 2 was set to six, the proportion of air in the enclosed cavity 3 inside the float 1 was more than 90%, ensuring that the float 1 floats while the air extraction efficiency is also the highest. Figure 3 The number of the air inlet holes 2 is set to six, and the six air inlet holes 2 are evenly divided into three groups, and any group of air inlet holes 2 is located at both ends of the diameter of the float 1, and the connecting lines between the three groups of air inlet holes 2 are perpendicular to each other. In this structure, the angle between two adjacent air inlet holes 2 is 90°. When the float 1 is placed on the water surface, 1 to 4 air inlet holes 2 are exposed to the air, which is convenient for gas inhalation.
[0027] It should be noted that in order to ensure that the float 1 can float on the water surface and perform effective water-gas separation, the angle between two adjacent air inlets 2 has a minimum angle α of 45° and a maximum angle β of 180°. According to the arc length calculation formula, arc length = nπR / 180° (n is the angle between two adjacent air inlets 2), it can be seen that the arc length between two adjacent air inlets 2 ranges from 0.785R to 3.14R.
[0028] refer to Figure 4 In this embodiment, the maximum number of air inlet holes 2 is set to fourteen, and the angle between two adjacent air inlet holes 2 is 45°. Combined with the previous embodiment, on the basis of six air inlet holes 2, any three adjacent air inlet holes 2 form an equilateral triangle, and the six air inlet holes 2 form eight equilateral triangles. An air inlet hole 2 is added at the center of each of the eight equilateral triangles. When the float 1 floats on the water surface, 1 to 12 air inlet holes 2 are exposed to the air, which is convenient for the inhalation of gas.
[0029] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
