Description

Technical Field

[0001] The utility model relates to the technical field of ship exhaust distribution scanning equipment, in particular to a ship exhaust distribution ultraviolet spectrum scanner. Background Art

[0002] The main reason why ship exhaust distribution needs to be scanned is to monitor and control the concentration and distribution of emissions. Ship exhaust usually contains various pollutants, such as nitrogen oxides (NOx), sulfur oxides (SOx), particulate matter, etc., which are harmful to the environment and human health. Exhaust samples are usually collected from the chimney of the ship. The ship exhaust distribution UV spectrometer is a device specially designed for ship exhaust analysis. It is usually installed around the chimney and uses ultraviolet spectroscopy technology to detect and measure the concentration of pollutants in the ship's exhaust. These pollutants can be detected and quantitatively analyzed using a specific wavelength range of the ultraviolet spectrum. When working, the ship exhaust distribution UV scanner takes into account the influence of external environmental factors such as wind direction on the exhaust distribution. These devices are generally equipped with additional sensors to monitor environmental conditions to ensure that the ship's exhaust can be scanned continuously and effectively.

[0003] Most wind direction sensors currently require power from batteries, which increases the operating cost and maintenance complexity of the equipment, especially in remote or powerless environments. Battery exhaustion not only causes the sensor to stop working, but also affects the continuity of data collection. Utility Model Content

[0024] Example

[0025] like Figure 1-3 As shown, the utility model proposes a ship exhaust distribution ultraviolet spectrum scanner, including an ultraviolet spectrum scanner body 1 installed beside the ship chimney to perform 180-degree sector scanning on the exhaust gas, and the ultraviolet spectrum scanner body 1 can cover a 180-degree sector range, that is, starting from a fixed point, scanning the entire semicircular area of ​​the spectrum. It also includes: a driving mechanism, which is arranged on the top of the ultraviolet spectrum scanner body 1 and rotates according to the wind direction while scanning the exhaust gas; a supporting mechanism installed at the bottom of the ultraviolet spectrum scanner body 1 to support the driving mechanism to avoid resistance when rotating.

[0026] Further, the driving mechanism includes a protective tube 11 fixedly wrapped on the outside of the ultraviolet spectrum scanner body 1, the top of the protective tube 11 is fixedly connected to a top cover 2, and the top of the top cover 2 is fixedly connected to a wind vane 3 that rotates automatically by wind. The wind vane 3 is a device or instrument used to indicate the wind direction. It is usually composed of an arrow or a marker with a direction indication fixed on a pillar or a bracket, and is placed in the open air or at a high place so that it can rotate freely and indicate the direction of the wind. The wind vane 3 uses the power of the wind to make the indicator align with the direction of the wind, thereby helping people to determine the direction of the wind and the change of the wind. The outer wall of the protective tube 11 is fixedly connected to a rearview mirror 5 that reflects all the exhaust gas that cannot be scanned by the rotating ultraviolet spectrum scanner body 1 for scanning by the ultraviolet spectrum scanner body 1. The rearview mirror 5 is provided with a heating element for quickly removing fog and ice and snow. The function of the heating element is that in cold weather conditions, the surface of the rearview mirror 5 is easy to freeze, thereby affecting the field of view scanned by the ultraviolet spectrum scanner body 1. The heating element can quickly melt the ice layer on the surface of the rearview mirror 5 to ensure that the rearview mirror 5 remains clear. In addition, in a humid or foggy environment, the rearview mirror 5 may fog up, obstructing the line of sight scanned by the ultraviolet spectrum scanner body 1. The heating element can effectively remove the fog and make the field of vision clearer by raising the temperature of the surface of the rearview mirror 5.

[0027] Secondly, the support mechanism includes a bottom cover 4 fixedly connected to the bottom of the protective tube 11, a second support rod 10 fixedly connected to the lower surface of the bottom cover 4, a rotating seat 12 fixedly connected to the bottom end of the second support rod 10, a positioning plug 13 fixedly connected to the lower surface of the rotating seat 12, an upper chuck 6 and a lower chuck 8 are provided on the rotating seat 12, a rotating through hole 61 for the second support rod 10 to move through is provided on the upper chuck 6, a rotating groove 62 for clamping the rotating seat 12 is provided on the upper chuck 6, and a mounting groove 15 is provided inside the lower chuck 8, and a bearing 14 connected to the rotating seat 12 is fixedly connected inside the mounting groove 15. The bearing 14 is a mechanical element used to reduce friction between moving parts, support rotation or linear motion, and thus improve the operating efficiency of the machine. A positioning hole for the positioning plug 13 to be inserted is provided in the middle of the bearing 14.

[0028] Furthermore, the lower surface of the lower chuck 8 is fixedly connected to the first support rod 9, and the bottom end of the first support rod 9 is fixedly connected to the mounting plate 16 fixed next to the chimney. The mounting plate 16 and the upper chuck 6 are both provided with a plurality of mounting bolts 7 distributed in a circular array, and the lower surface of the lower chuck 8 is provided with a plurality of nuts adapted to the mounting bolts 7 on the upper chuck 6.

[0029] In this embodiment, when it is necessary to use a ship exhaust distribution ultraviolet spectrum scanner, such as Figure 1 As shown, the mounting plate 16 is installed next to the chimney of the ship through a plurality of mounting bolts 7 on the mounting plate 16. Afterwards, the ultraviolet spectrum scanner body 1 is first aligned with the chimney, and then the ultraviolet spectrum scanner body 1 can scan the exhaust gas discharged from the chimney. When the exhaust gas discharged from the chimney is blown by the wind, it changes with the wind direction. At this time, the wind vane 3 on the upper surface of the top cover 2 is blown by the wind, and the wind will exert force on the sensitive components on the wind vane 3, so that the wind vane 3 rotates to a position aligned with the direction of the wind. The exhaust gas discharged from the chimney will also float in the direction of the wind, and at this time, the ultraviolet spectrum scanner body 1 will scan the exhaust gas discharged from the chimney. When the wind direction is completely opposite to the previous direction, the ultraviolet spectrum scanner body 1 can also scan the exhaust gas through the reflection of the rearview mirror 5. The chimney exhaust gas is scanned 180° forward by the ultraviolet spectrum scanner body 1, and the ultraviolet spectrum scanner body 1 scans the chimney exhaust gas 180° in the reverse direction through the rearview mirror 5. Finally, when the ultraviolet spectrum scanner body 1 is rotated to any angle, the chimney exhaust can be scanned, which is simple and convenient; when the wind vane 3 is driven by the wind to rotate the top cover 2, the top cover 2 drives the protective tube 11, the bottom cover 4, the second support rod 10, the rotating seat 12 and the positioning plug 13 to rotate in turn, and the rotating rotating seat 12 rotates in the rotating groove 62 in the upper chuck 6. At the same time, the rotating seat 12 is clamped into the bearing 14 through the positioning plug 13 and rotates very smoothly through the support of the bearing 14.

[0030] The preferred embodiments of the utility model of the above utility model are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
