[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.
[0027] Please refer to Figure 1 and Figure 2, this embodiment provides an anti-condensation water structure of a combustible gas detector, which includes a detector body 1, a drainage tube and a connection structure for fixing the detector body 1. The detector body 1 can use a currently conventional combustible gas detector. A connection port connected to the drainage tube is opened on one side. In addition, a reserved port can also be opened on the outer shell of the detector body 1. A plug screw 3 is connected to the reserved port, and a first sealing ring 2 is arranged between the plug screw 3 and the reserved port to prevent water from seeping into the detector body 1 from the reserved port. According to actual needs, when the reserved port is not required, the plug screw 3 is used for sealing. When the reserved port is required, the plug screw 3 is removed, which is equivalent to having an additional connection port for use. One end of the drainage tube is connected to the connection port of the detector body 1. The drainage tube is divided into two parts: a connecting portion and at least one guide portion 6. The connecting portion is a conventional pipeline portion, which is nothing special and can be routed according to the usual design layout. The guide part 6 must be arranged vertically or inclined, and the lowest point of the guide part 6 must be lower than the horizontal plane of the connection between the drainage tube and the detector body 1. At the same time, a drainage groove must be provided at the bottom of the guide part 6 to cover and restrict the shape of the cable, and to allow the condensed water on the cable to sink to the bottom and fall downward by gravity, and be discharged through the drainage groove instead of flowing into the detector body 1. In this embodiment, Figure 3 As shown, the guide portion 6 is configured to be U-shaped. One end of the U-shaped guide portion 6 is detachably connected to the connection port on the detector body 1 through a cable gland 10, and a threading rubber ring 4 and a sealing ring gasket 5 are sequentially arranged at the junction of the cable gland 10 and the connection port to further enhance the sealing performance. The other end of the guide portion 6 is the connection portion. The connection portion is connected to the external part through a quick-install structure. The opening of the U-shaped guide portion 6 is arranged upward, and the horizontal plane of the bottom cross tube thereof is lower than the position of the connection port. At the same time, a drainage groove is provided at the bottom and outer edge of the guide portion 6. The cross-sectional shape of the drainage groove is a trumpet shape that gradually expands toward the outside of the guide tube, such as Figure 4 As shown. To address the problem of condensed water, a hollow U-shaped guide portion 6 and a matching drainage groove are used. When condensed water appears on the cable or pipe, the water droplets will flow to the bottom along the guide portion 6, and will not penetrate into the detector body 1 along the line. A drainage groove is provided at the bottom of the guide portion 6. When installing the guide pipe, there is no need to thread the wire. The cable can be inserted through the drainage groove, which reduces the time and process of removing the wire during threading. After the guide portion 6 is directly clamped on the cable, the cable remains in a U shape, and finally the condensed water on the cable falls to the lower end and flows out through the drainage groove.
[0028] In other embodiments, Figure 5 As shown, based on the above principle, the guide portion 6 can also be set to a V-shape ( Figure 5 a part of the equation) or √ type ( Figure 5b part in the figure), keep its lowest point lower than the connection port. In this embodiment, the quick-install structure on the connection part includes a waterproof male connector 8 and a waterproof female connector 9. The waterproof male connector 8 is fixedly connected to the connection part of the drainage tube, and a second sealing ring 7 is provided at the connection point. The waterproof female connector 9 and the waterproof male connector 8 are pluggable. Guide grooves and anti-falling buckles are provided on the waterproof female connector 9 and the waterproof male connector 8. When the waterproof male connector 8 is inserted into the waterproof female connector 9 along the guide groove, the waterproof male connector 8 is sent inward along the inclined surface of the buckle until it reaches the bottom and is hooked by the end of the buckle, so that the waterproof female connector 9 and the waterproof male connector 8 are not difficult to insert and connect, but are not easy to loosen or pull out.
[0029] The connection structure in this embodiment includes a base plate 11, a support plate and a back plate 13. The base plate 11 can be fixed to the roof with expansion screws. When there is a steel frame at the installation site, holes can be punched on the steel frame according to the position of the screw holes of the base plate 11, or the base plate 11 can be fixed to the steel frame using a clamp. The upper end of the support rod 12 is connected to the base plate 11, and the lower end is connected to the back plate 13. The back plate 13 is used to install the detector body 1. In other embodiments, the support rod 12 and the base plate 11 can be rotatably connected by a rotating shaft, and the rotating surface of the support rod 12 is parallel to the plate surface direction of the base plate 11, so that the support rod 12 can rotate within a hemispherical range, which is convenient for hanging. In addition, the support rod 12 can also be divided into two sections. The two sections of the support rod 12 are connected by threads, and the total length of the support rod 12 can be adjusted by the relative rotation between the two sections of the support rod 12, which is convenient for adjusting the installation height of the detector body 1.
[0030] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
