Description

Technical Field

[0001] The invention relates to an adjustable fixing device for a probe of an LNG gas detection system, and belongs to the technical field of ship design. Background Art

[0002] As the international community pays more and more attention to green environmental protection and the shipping industry continues to develop, more and more new energy technologies are being applied in the field of ships, among which LNG (liquefied natural gas) has become an important environmentally friendly fuel due to its clean, environmentally friendly, economical and efficient characteristics. However, its low boiling point and flammable and explosive characteristics in the gas state bring many safety hazards. In order to avoid danger and timely detect whether LNG pipelines and storage equipment are leaking, ships using LNG as fuel need to be equipped with LNG gas detection systems.

[0003] At present, conventional LNG gas detection system probes are divided into infrared and catalytic reduction types. The two types of probes have different requirements for detection range and installation angle. For bases with different detection angles, repeated purchases are required, and the design cost, procurement cost and production cost are high. After the ship is built, the probes with inappropriate angles need to be adjusted. Generally, the probes are arranged at a higher position in the cabin or living room, and it is extremely difficult to modify the fixed base. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides an adjustable fixing device for a probe of an LNG gas detection system, so as to adjust the direction and angle of the LNG gas probe.

[0005] The technical means adopted by the present invention are as follows: an adjustable fixing device for a probe of an LNG gas detection system, the device comprising a device fixing part, a rotating mounting plate, a probe fixing part and an LNG probe; a fixing part flange is arranged at the end of the device fixing part, a rotating part flange is arranged at the end of the rotating mounting plate, and the fixing part flange and the rotating part flange are connected by bolts;

[0006] One end of the probe fixing piece is provided with a probe mounting base connected to the LNG probe, and the other end is connected to the rotating mounting piece through an angle bolt;

[0007] The device includes adjustment of the probe direction and the probe angle. The probe direction is adjusted by rotating the mounting plate to the required installation direction, and then connecting the rotating flange with the fixing flange to achieve the adjustment of the probe direction; the probe angle is adjusted by the probe fixing part driving the LNG probe to rotate around the angle bolt to achieve 180° angle adjustment of the probe on the plane of the probe fixing part.

[0009] At least two rotating part flange holes are connected to the fixed part flange holes through bolts.

[0010] The adjustment angle of the probe direction is determined by the number of the flange holes of the rotating part.

[0011] Compared with the prior art, the present invention has the following advantages: the device includes a device fixing, a rotating mounting plate, a probe fixing part and an LNG probe. After the ship is built, the angle of the LNG gas probe needs to be adjusted in combination with the specific position of the LNG gas probe and the adjustment of the equipment or area to be detected. In the present invention, the direction of the probe is adjusted by adjusting the rotating mounting plate to the required installation direction, and then connecting the rotating flange with the fixing flange to achieve the adjustment of the probe direction. The angle of the probe is adjusted by the probe fixing part driving the LNG probe to rotate around the angle bolt to achieve a 180° angle adjustment of the probe on the plane of the probe fixing part.

[0018] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0022] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0024] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
