[0002] Flame detectors used on offshore oil platforms are specially designed to detect fires quickly and accurately. These detectors can typically monitor large areas and are crucial for ensuring the safety of offshore platforms. These devices and technologies work together to improve the safety of offshore oil platforms, prevent fires from occurring, or effectively control fires in their early stages.

[0003] On offshore oil platforms, the harsh environment, high humidity, and salt spray, coupled with the accumulation of dust and grime from years of construction projects, especially anti-corrosion work, severely impact the performance of these highly sensitive detectors. This leads to problems such as failure to trigger alarms or false alarms during routine maintenance and testing. Some detectors are installed at heights of up to eight meters, making the use of ladders for maintenance and cleaning impractical. The current method involves using a stainless steel instrument tube covered with a rag to attempt cleaning the flame detectors. However, this method is top-heavy and ineffective at cleaning the detector lenses, and there is a risk that the instrument tube may puncture the rag and damage the detector lenses. Furthermore, the instruments are typically around 6 meters long and lack telescopic design, making them inconvenient to carry and difficult to maintain in confined spaces such as between tanks, posing safety hazards and hindering their use. Utility Model Content

[0004] The purpose of this invention is to provide a retractable flame probe lens cleaning device to solve the problem mentioned in the background art, where flame probes on offshore oil platforms become dirty due to the influence of humid environments, salt spray, and construction dust, affecting detection efficiency and causing maintenance difficulties, especially for probes at a height of eight meters. Existing cleaning methods use stainless steel instrument tubes covered with cloths, but this method is ineffective and carries the risk of damaging the probe, making it difficult to implement effectively.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A retractable flame probe lens cleaning device includes a support rod, the inner cavity of which is provided with a lifting assembly, the lifting assembly including a positioning rod, the top of which is fixedly connected to the bottom of the support rod, the inner cavity of the support rod being provided with a first moving rod, a second moving rod and a third moving rod in sequence from the outside to the inside, the top of the third moving rod being provided with a cleaning assembly, the cleaning assembly including a welding rod, the bottom end of which is installed with the top end of the third moving rod.

[0006] Preferably, a threaded rod is provided through the inner cavity of the support rod, and the top end of the threaded rod extends into the inner cavity of the third moving rod.

[0007] Preferably, the outer surface of the threaded rod is threaded with three threaded plates, and the tops of the three threaded plates are fixedly connected to the bottoms of the first moving rod, the second moving rod, and the third moving rod, respectively.

[0008] Preferably, a connecting rod is provided through the inner cavity of the positioning rod, and the top end of the connecting rod is fixedly connected to the bottom end of the threaded rod.

[0033] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a retractable flame probe lens cleaning device.

[0034] like Figures 1-9As shown, this utility model discloses a retractable flame probe lens cleaning device, comprising a support rod 1. The inner cavity of the support rod 1 is equipped with a lifting assembly 2, which includes a positioning rod 21. The top of the positioning rod 21 is fixedly connected to the bottom of the support rod 1. The inner cavity of the support rod 1 is sequentially provided with a first moving rod 22, a second moving rod 23, and a third moving rod 24 from the outside to the inside. The second moving rod 23 is located within the inner cavity of the first moving rod 22, and the third moving rod 24 is also located within the inner cavity of the second moving rod 23. The support rod 1 has a height of 2000 mm, an outer diameter of 20 mm, and an inner diameter of 18 mm. The first moving rod 22 has a height of 1000 mm, and the second moving rod 23 has a height of 1000 mm. The height of the third moving rod 24 is 1,000 millimeters, and the third moving rod 24 can be housed by the second moving rod 23, the second moving rod 23 can be housed by the first moving rod 22, and the first moving rod 22 can be housed by the support rod 1, thereby achieving the purpose of multi-level telescopicity. This allows for cleaning and wiping of flame probe lenses installed at different heights and facilitates the carrying of the overall structure. The top of the third moving rod 24 is provided with a cleaning component 3, which includes a welding rod 31. The bottom end of the welding rod 31 is installed with the top end of the third moving rod 24. The outer surface of the welding rod 31 is provided with an external thread, while the outer surface of the third moving rod 24 is provided with an internal thread interface that matches the external thread of the welding rod 31.

[0035] like Figures 2-9 As shown, a threaded rod 25 is provided through the inner cavity of the support rod 1, and the top end of the threaded rod 25 extends into the inner cavity of the third moving rod 24. The outer surface of the threaded rod 25 has external threads, and three threaded plates 26 are threadedly connected to the outer surface of the threaded rod 25. The inner side of each threaded plate 26 has an internal thread that matches the external thread of the threaded rod 25. The tops of the three threaded plates 26 are fixedly connected to the bottoms of the first moving rod 22, the second moving rod 23, and the third moving rod 24, respectively, and the outer surfaces of the three threaded plates 26 are respectively connected to the inner surfaces of the support rod 1, the first moving rod 22, and the second moving rod 23. The cavity is slidably connected, wherein the support rod 1, the first moving rod 22, the second moving rod 23 and the third moving rod 24 are made of PVC pipe, which is lightweight, reasonably priced and of suitable weight, which can minimize the weight carried by the operator, has high feasibility and achieves low cost and high effectiveness. The inner cavity of the positioning rod 21 is provided with a connecting rod 27, the top end of the connecting rod 27 is fixedly connected to the bottom end of the threaded rod 25, and the bottom end of the connecting rod 27 extends to the outside of the bottom of the positioning rod 21 and is fixedly connected to a handwheel. The contact area between the connecting rod 27 and the threaded rod 25 is rotatably connected by a bearing.

[0036] like Figures 3-9As shown, a fixing block 32 is provided at the end of the welding rod 31 away from the support rod 1. A placement plate 33 is fixedly connected to the left side of the fixing block 32. Two rotating rods 34 arranged symmetrically front and back are rotatably connected to the inner side of the placement plate 33. A soft brush 35 is connected to the opposite end of the two rotating rods 34. The soft brush 35 has a volume of 200 mm and is spherical, which facilitates wiping the flame probe lens. When extended, it can reach a maximum length of 5000 mm, which can clean the flame probe lens at high altitudes. When retracted, it is as short as 2000 mm, which is convenient for carrying and storage. The fixing block 32 has two... A locking hole 36 is provided. A fixing plate 37 is fixedly connected to the outer surfaces of both the front and rear sides of the welding rod 31. A locking rod 38 is provided through one side of the fixing plate 37, and one end of the locking rod 38 contacts the inner cavity of the locking hole 36. A return spring 39 is sleeved on the outer surface of the locking rod 38.

The outer surface of the connecting rod 27 is coated with a pattern, and a handle is fixedly connected to the outer surface of the connecting rod 27 to facilitate the user to carry the support rod 1 for wiping work.

[0037] Specifically, the user manually rotates the handwheel to rotate the connecting rod 27, which in turn rotates the threaded rod 25. Utilizing the threaded transmission principle, the threaded rod 25 pushes the threaded plate 26 upward, causing the first moving rod 22, the second moving rod 23, and the third moving rod 24 to move upward simultaneously. Ultimately, this causes the soft brush 35 to adjust its height as needed, effectively cleaning flame probe lenses installed at different heights. When the soft brush 35 needs cleaning after a period of use, the two locking rods 38 can be manually pulled in opposite directions to compress the return spring 39, disengaging the locking rods 38 from the locking holes 36. This allows for easy removal of the soft brush 35 for external cleaning, ensuring its cleaning efficiency and maintaining the high cleanliness of the flame probe lens, simplifying the maintenance process and improving work efficiency.

[0038] The working principle of a retractable flame probe lens cleaning device is as follows: First, when cleaning flame probe lenses at different installation heights on an offshore oil platform, the user manually operates the lifting component 2 to move the soft brush 35 to the height position, and then manually operates the soft brush 35 to wipe and clean the lens. After cleaning, if it is necessary to disassemble the soft brush 35 for external cleaning or replacement, the cleaning component 3 can be operated to disassemble or install the soft brush 35, which improves the cleanliness of the lens wiping and facilitates use.
