[0002] In order to monitor the fume emissions of the urban catering industry, online monitoring devices for catering fume have been actively promoted in major cities across the country. The existing online monitoring devices for catering fume mainly consist of a sampling tube, a monitoring device box (containing fume sensors, control panels, air pumps, etc.) and an information platform.

[0003] Most monitoring instrument boxes are installed and fixed on the exhaust duct and are located between the fan and the purifier. Exhaust ducts have various shapes, among which square or circular cross-sections are the main ones. During actual installation, one end of the sampling tube is fixed on the monitoring instrument box, and the other end needs to be fixed on the exhaust duct to play a sampling and fixing role.

[0004] Since the smoke exhaust pipe will vibrate during actual operation, it is difficult to firmly fix the sampling tube on the smoke exhaust pipe using the existing connection structure; and when a rigid connection structure is used, the vibration of the smoke exhaust pipe is easily transmitted to the monitoring instrument box, which in turn causes the fasteners to loosen and the welding points of the sampling tube to fall off. Therefore, it is necessary to design a mounting structure that can firmly install the sampling tube and has a buffering and shock-absorbing function. Utility Model Content

[0005] In view of the problems existing in the prior art: the existing connection structure makes it difficult to firmly fix the sampling tube on the smoke exhaust duct, and easily causes the vibration of the smoke exhaust duct to be transmitted to the monitoring instrument box, causing the fasteners to loosen. The purpose of the utility model is to provide a shock-absorbing installation structure for an oil fume monitoring device, which fixes the smoke tube connecting plate used to fix the sampling tube on the smoke exhaust duct through threaded connectors and flexible pads, thereby ensuring the firm installation of the sampling tube and utilizing the flexible pads as a buffer to absorb the vibration energy of the smoke exhaust duct and prevent the fasteners from loosening. The utility model has the advantages of simple structure, convenient and quick installation, and a wide range of applicability.

[0037] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application.

[0038] It should be noted that the embodiments of the present invention and the features involved in the embodiments can be combined with each other without conflict. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] As attached Figure 1-3 As shown, a shock-absorbing installation structure of an oil fume monitoring device includes a sampling device 3, and the sampling device 3 includes a sampling tube 31. The sampling tube 31 is a hollow long tube, one end of which is installed on the monitoring instrument box 1 and the other end extends into the exhaust pipe 2, so as to send the oil fume in the exhaust pipe 2 to the detection device in the monitoring instrument box 1.

[0041] The sampling device 3 further includes a box connecting plate 32 , a smoke tube connecting plate 33 and a reinforcing structure 34 .

[0042] The box connecting plate 32 is a flat plate structure, and the sampling tube 31 passes through the box connecting plate 32. The box connecting plate 32 limits the sampling tube 31 and is fixedly connected to the sampling tube 31. The box connecting plate 32 is provided with holes for bolts to pass through. The box connecting plate 32 is fixedly mounted on the monitoring instrument box 1 by bolt connection, and then the end of the sampling tube 31 close to the monitoring instrument box 1 is fixed on the monitoring instrument box 1.

[0043] The smoke tube connecting plate 33 is also a flat plate structure. The sampling tube 31 passes through the smoke tube connecting plate 33 . The smoke tube connecting plate 33 also has a limiting and fixing function for the sampling tube 31 .

[0044] The reinforcing structure 34 is disposed between the box connecting plate 32 and the smoke pipe connecting plate 33, and is used to improve the structural strength between the box connecting plate 32 and the smoke pipe connecting plate 33. In this embodiment, the reinforcing structure 34 is a reinforcing rib plate, the two ends of which are respectively fixedly connected to the box connecting plate 32 and the smoke pipe connecting plate 33, and the bottom end of which is fixedly connected to the sampling tube 31.

[0045] As attached Figure 4 As shown, the smoke tube connecting plate 33 in this embodiment is in a triangular structure as a whole, so that the smoke tube connecting plate 33 has high stability. The smoke tube connecting plate 33 is provided with a sampling hole 331 for the sampling tube 31 to pass through and to limit the sampling tube 31.

[0046] In some other embodiments, the smoke tube connection plate 33 is a polygonal structure, such as a quadrilateral, a pentagon, etc. A plurality of fixing holes 332 may be provided on the smoke tube connection plate 33 according to its outer shape. For example, a quadrilateral smoke tube connection plate 33 may have a fixing hole 332 at each of the four corners, and a pentagonal smoke tube connection plate 33 may have a fixing hole at each of the five corners. In this embodiment, three fixing holes 332 are provided on the smoke tube connection plate 33, and the three fixing holes 332 are respectively located at the three corners of the smoke tube connection plate 33. In addition, the center line of the two fixing holes 332 at the bottom of the smoke tube connection plate 33 is horizontal, and the center line of the fixing hole 332 at the top of the smoke tube connection plate 33 and the sampling hole 331 is vertical and passes through the midpoint of the center line of the two fixing holes 332 at the bottom of the smoke tube connection plate 33.

[0047] As attached Figure 5-9 As shown, the shock-absorbing installation structure of the oil smoke monitoring device further includes an installation component 4. The installation component 4 is used to fix the smoke pipe connecting plate 33 on the smoke exhaust pipe 2. The installation component 4 includes a threaded connector 41 and a flexible pad 42.

[0048] One end of the threaded connector 41 passes through the fixing hole 332 on the smoke pipe connecting plate 33 and is screwed into the smoke exhaust pipe 2, and each threaded connector 41 passes through a corresponding fixing hole 332. In order to facilitate on-site installation and avoid the process of drilling holes on the smoke exhaust pipe 2 during installation, the threaded connector 41 in the utility model is preferably a self-drilling screw. A self-drilling screw, also classified as a self-tapping screw, is a type of existing screw, and its tip can drill a hole by itself.

[0049] The flexible pad 42 is a cylindrical structure, which is sleeved on the threaded connector 41, so that the flexible pad 42 can be clamped between the smoke pipe connecting plate 33 and the smoke exhaust pipe 2. The flexible pad 42 in the utility model is made of a flexible material with certain elasticity, such as rubber.

[0050] A circular limiting groove 421 is provided on the outer wall of the flexible pad 42, and the axis of the limiting groove 421 coincides with the axis of the flexible pad 42. The limiting groove 421 is located at the middle position of the axis direction of the flexible pad 42. The shape and size of the limiting groove 421 are adapted to the fixing hole 332, so that the limiting groove 421 can limit the smoke pipe connecting plate 33.

[0051] The fixing hole 332 in the present invention is a groove formed at the edge of the smoke tube connecting plate 33, that is, the fixing hole 332 is connected to the edge of the smoke tube connecting plate 33. Since the smoke tube connecting plate 33 is triangular in shape and the three fixing holes 332 are respectively located at the three corner positions, and the opening directions of the three fixing holes 332 are all in the direction away from the center of the smoke tube connecting plate 33, this design can ensure the fixing effect of the smoke tube connecting plate 33 while allowing a certain size deviation in the positional relationship between the three threaded connectors 41, thereby improving the flexibility during installation and facilitating actual installation.

[0052] The flexible pad 42 is provided with a plurality of buffer slopes 422 along its axial direction. In this embodiment, buffer slopes 422 are provided at both ends of the flexible pad 42 and both sides of the limiting groove 421. The buffer slopes 422 provide a certain deformation space for the flexible pad 42 to deform when subjected to an axial extrusion force, which is beneficial to improving the connection stability between the smoke pipe connecting plate 33 and the smoke exhaust pipe 2.

[0053] During actual installation, due to the inconsistency of the shape or posture of the smoke exhaust pipe 2, in order to ensure the stable installation between the flat smoke pipe connecting plate 33 and the smoke exhaust pipe 2, at least one flexible pad 42 is sleeved on each threaded connector 41. That is, by adjusting the number of flexible pads 42 sleeved on the threaded connector 41, the problem of different height differences between the outer wall of the smoke exhaust pipe 2 and the smoke pipe connecting plate 33 at different positions can be solved. For example, in this embodiment, the smoke exhaust pipe 2 is a vertically arranged circular tubular structure, then two flexible pads 42 need to be sleeved on the threaded connector 41 passing through the bottom fixing hole 332 of the smoke pipe connecting plate 33, while only one flexible pad 42 needs to be sleeved on the threaded connector 41 passing through the top fixing hole 332 of the smoke pipe connecting plate 33.

[0054] The implementation principle of the above embodiment is:

[0055] One end of the sampling tube 31 is fixedly mounted on the monitor box 1 through the box connecting plate 32, and the other end of the sampling tube 31 passes through the sampling hole 331 on the smoke pipe connecting plate 33 and extends into the smoke exhaust pipe 2. After the required number of flexible pads 42 are put on the threaded connector 41, the limiting groove 421 on the flexible pad 42 is aligned with the fixing hole 332 on the smoke pipe connecting plate 33, until the flexible pad 42 completely enters the fixing hole 332, and then the threaded connector 41 is tightened. During the tightening process, the flexible pad 42 is axially squeezed between the smoke pipe connecting plate 33 and the outer wall of the smoke exhaust pipe 2, and the flexible pad 42 is deformed to a certain extent, ensuring that the flat smoke pipe connecting plate 33 can be firmly installed on the smoke exhaust pipe 2, thereby strengthening the connection strength between the sampling tube 31 and the smoke exhaust pipe 2. At the same time, the flexible pad 42 can buffer and absorb the vibration energy of the smoke exhaust pipe 2, reduce the impact of the vibration of the smoke exhaust pipe 2 on the sampling tube 31, the smoke pipe connecting plate 33 and the monitoring instrument box 1, and prevent the threaded connector 41 from loosening.

[0056] Embodiment 2

[0057] As attached Fig.10 As shown, a shock-absorbing installation structure of a fume monitoring device disclosed in the utility model is shown. Different from the first embodiment, the exhaust pipe 2 is a horizontally arranged circular tube structure.

[0058] At this time, two flexible pads 42 need to be mounted on the threaded connector 41 passing through the top fixing hole 332 of the smoke pipe connecting plate 33, while only one flexible pad 42 is required to be mounted on the threaded connector 41 passing through the bottom fixing hole 332 of the smoke pipe connecting plate 33.

[0059] Embodiment 3

[0060] As attached Fig.11 As shown, a shock-absorbing installation structure of a fume monitoring device disclosed in the utility model is shown. Different from the first embodiment, the exhaust pipe 2 is a horizontally arranged square tube structure.

[0061] At this time, since the outer wall of the smoke exhaust pipe 2 is also a flat plate structure, only one flexible pad 42 needs to be sleeved on all the threaded connectors 41 passing through the smoke pipe connecting plate 33 .

[0062] Embodiment 4

[0063] As attached Fig.12As shown, the difference between this embodiment and the second embodiment is that a shock-absorbing sleeve 3311 is provided between the sampling tube 31 and the smoke exhaust pipe 2. The shock-absorbing sleeve 3311 is cylindrical in shape as a whole and is sleeved on the outer wall of the sampling tube 31, thereby avoiding the vibration transmission caused by the direct contact between the sampling tube 31 and the smoke exhaust pipe 2. The shock-absorbing sleeve 3311 is also made of a rubber material with a certain elasticity and shock-absorbing effect, which has the function of further reducing the influence of the vibration of the smoke exhaust pipe 2 on the sampling tube 31, the smoke pipe connecting plate 33 and the monitoring instrument box 1.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
