Description

Technical Field

[0001] This utility model relates to the field of marine diesel engine technology, and in particular to an observation window cleaning device, an observation window, and a marine diesel engine. Background Technology

[0002] For large mechanical equipment, such as marine diesel engines, the number of internal components is large, requiring frequent monitoring of their operating status. However, due to considerations of the equipment's operating environment and personnel safety, close observation inside the equipment is often not possible. Typically, observation windows are installed at corresponding locations on the equipment body. However, as the equipment operates, oil and other impurities easily accumulate on the inside of these windows, obstructing visibility and necessitating disassembly and cleaning. One related technology provides a washable observation window that allows for cleaning of oil and other impurities on the inside of the window during daily use without disassembly. After prolonged use, disassembly and maintenance of the cleaning device are still required. This necessitates removing the observation window and cleaning device from the machine body, requiring entry into the equipment. This disassembly process is cumbersome, and for some continuously operating equipment, entering the equipment for work poses significant safety risks. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Example 1

[0028] like Figures 1-3 As shown, this utility model provides an observation window cleaning device for installation on the observation window of large machinery equipment, and for cleaning the transparent body 200 of the observation window. The observation window cleaning device includes an installation component and a cleaning component. The installation component includes a first flange 11 and a second flange 12. The first flange 11 is used for fixed connection to the machine body 100, such as bolt connection or welding connection. In this embodiment, the first flange 11 is preferably welded to the machine body 100. The second flange 12 is detachably connected to the first flange 11. The first flange 11 and the second flange 12 together form an installation groove 33 for installing the transparent body 200 of the observation window, thereby realizing the installation and fixation of the transparent body 200. The cleaning component includes a rotating shaft 3 and a scraper 4. The rotating shaft 3 passes through the transparent body 200 and is rotatably connected to the transparent body 200. The scraper 4 is installed at one end of the rotating shaft 3 near the machine body 100, and the scraper 4 is attached to the side of the transparent body 200 facing the machine body 100, thereby realizing the cleaning of the transparent body 200. The transparent body 200 with the observation window is installed in the mounting groove 33 formed by the first flange 11 and the second flange 12. The first flange 11 and the second flange 12 are detachably connected. The transparent body 200 can be cleaned by the cleaning component. When disassembly and maintenance are required, the transparent body 200 and the cleaning component can be disassembled and assembled by removing and assembling the second flange 12. The convenience of disassembly and assembly is improved, and there is no need to enter the equipment for disassembly and assembly, thus ensuring the safety of the operators.

[0029] Furthermore, the inner bore of the first flange 11 is a stepped bore, with the larger end of the inner bore of the first flange 11 located away from the body 100. The side of the transparent body 200 facing the body 100 abuts against the stepped surface of the inner bore of the first flange 11. The second flange 12 is bolted to the first flange 11, and the second flange 12 abuts against the side of the transparent body 200 away from the body 100. After the second flange 12 is bolted to the first flange 11, the transparent body 200 is pressed against the stepped surface of the inner bore of the first flange 11, thereby achieving the installation of the transparent body 200. When disassembly is required, the bolts connecting the second flange 12 and the first flange 11 are removed, and the second flange 12 is taken off, thereby removing the transparent body 200 and the cleaning components connected to the transparent body 200 together, improving the convenience of disassembly and assembly.

[0030] Specifically, a first buffer element 21 is provided between the transparent body 200 and the first flange 11, and a second buffer element 22 is provided between the transparent body 200 and the second flange 12. The first buffer element 21 and the second buffer element 22 serve two purposes: firstly, to prevent moisture, dust, and oil from entering the equipment through the gaps between the transparent body 200 and the first flange 11 and the second flange 12; and secondly, to effectively prevent wear between the transparent body 200 and the first flange 11 and the second flange 12. The first buffer element 21 is made of silicone, rubber, or resin; the second buffer element 22 is also made of silicone, rubber, or resin. In this embodiment, both the first buffer element 21 and the second buffer element 22 are made of rubber to achieve both sealing and cushioning.

[0031] Furthermore, the rotating shaft 3 is equipped with a collar 31, which is attached to the side of the transparent body 200 facing away from the machine body 100. By providing the collar 31, the collar 31 and the scraper 4 together restrict the axial sliding of the rotating shaft 3 relative to the transparent body 200. A mounting groove 33 is provided at the end of the rotating shaft 3 closest to the machine body 100, and part of the scraper 4 is located within the mounting groove 33. The scraper 4 is fixedly connected to the rotating shaft 3 by means of adhesive or snap-fit, preventing it from falling off during the cleaning of the transparent body 200.

[0032] Optionally, the rotating shaft 3 is also provided with an annular groove 32, in which a rolling element (not shown in the figure) is installed. The rotating shaft 3 rotates relative to the transparent body 200 via the rolling element. The rolling element can be a cylindrical roller or a ball. By providing the rolling element, the sliding friction during the rotation of the rotating shaft 3 relative to the transparent body 200 is converted into rolling friction, reducing wear. In addition, there can be two or more annular grooves 32 to further reduce wear between the rotating shaft 3 and the transparent body 200.

[0033] Optionally, the transparent body 200 is made of glass or transparent acrylic. In this embodiment, the transparent body 200 is preferably made of glass. The scraper 4 is preferably made of metal, such as iron or aluminum alloy. A handle is connected to the end of the rotating shaft 3 away from the machine body 100. By operating the handle, the rotating shaft 3 is rotated, thereby causing the scraper 4 to rotate close to the side of the transparent body 200 facing the machine body 100, ensuring a good field of view. After long-term use, when it is necessary to repair or replace related parts, remove the bolts between the second flange 12 and the first flange 11, remove the second flange 12, and then remove the transparent body 200 and the cleaning assembly together. After repairing or replacing the related parts, reassemble the cleaning assembly and the transparent body 200, place the transparent body 200 on the stepped surface of the first flange 11, and finally fasten the second flange 12 and the first flange 11 together with bolts. The disassembly and assembly process is simple and does not require entering the equipment, ensuring the safety of the operator.

[0034] This invention provides an observation window, including a transparent body 200 and an observation window cleaning device as described in this embodiment. The transparent body 200 is installed within an installation assembly. By incorporating the observation window cleaning device in this embodiment, the convenience of disassembling the observation window is improved while satisfying the need for daily cleaning.

[0035] This invention provides a marine diesel engine, including the observation window described in this embodiment. By providing the observation window, the internal operating conditions of the marine diesel engine can be effectively observed at all times, making disassembly and assembly more convenient during maintenance and reducing maintenance time.

[0036] Example 2

[0037] To avoid repetition, this embodiment will only describe the differences from Embodiment 1. The difference between this embodiment and Embodiment 1 is that the observation window cleaning device in this embodiment also includes an anti-detachment component 6.

[0038] like Figure 4 As shown, an anti-detachment component 6 is also connected to one end of the rotating shaft 3 near the machine body 100. The anti-detachment component 6 passes through the rotating shaft 3 radially. The anti-detachment component 6 is perpendicular to the scraper 4, and the scraper 4 is fixed in the mounting groove 33 by the anti-detachment component 6. By setting the anti-detachment component 6 to limit the scraper 4, the scraper 4 is more reliably fixed in the mounting groove 33, avoiding the scraper 4 from falling off due to snap-fit ​​failure or welding failure. The anti-detachment component 6 is preferably a pin with a cotter pin or a bolt with a lock nut to prevent it from falling off.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
