Abstract
Description
Technical Field
[0001] This application relates to the technical field of hydrogen detection, and in particular to an automatically cleanable hydrogen detector. Background Technology
[0002] A hydrogen detector is an instrument used to detect the concentration of hydrogen in the environment. It is widely used in chemical, energy, and metallurgical industries where there is a risk of hydrogen leakage. After a period of use, to ensure the hydrogen detector functions properly, its exterior needs to be cleaned. Gently wipe the detector's casing with a clean, soft, damp cloth to remove dust and stains. If stains are stubborn, a small amount of neutral detergent can be applied, but care should be taken to avoid getting detergent inside the instrument.
[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: existing hydrogen detectors cannot be self-cleaned after a period of use and require manual cleaning with auxiliary tools. During the cleaning process, workers are prone to damaging the hydrogen detector itself, and the cleaning is not thorough enough, affecting the normal use of the hydrogen detector in the future. Water or other cleaning liquids can easily enter the interior of the hydrogen detector, causing damage to the internal electronic components. Utility Model Content

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] This application discloses an automatically cleanable hydrogen detector. For example... Figure 1As shown, the device includes a base plate 1. A detector body 2 is fixedly mounted on the center of the upper surface of the base plate 1. A cleaning ring 15 is slidably sleeved on the center of the outer side of the detector body 2. The cleaning ring 15 is a sponge, which effectively absorbs the cleaning agent and water flowing from the feed pipe 18. This allows the cleaning ring 15 to repeatedly wipe the outer wall of the hydrogen detector. The inner side of the cleaning ring 15 has inward grooves, and the uneven surface of the cleaning ring 15 makes wiping more thorough. The outer side of the cleaning ring 15 is connected to... A feed pipe 18 is provided, with its bottom perpendicular to the cleaning ring 15. The feed pipe 18 facilitates the entry of external liquid into the cleaning ring 15. The feed pipe 18 is perpendicular to the discharge pipe 17 and is set at a right angle. The top of the feed pipe 18 is provided with a feed hole and is tapered. The diameter of the feed pipe 18 is smaller than the inner diameter of the discharge pipe 17. The right-angled feed pipe 18 facilitates connection with the discharge pipe 17 above after a period of operation, allowing the liquid inside the discharge pipe 17 to flow out through the discharge pipe 18.
[0025] Please see Figure 2 A fixing block 14 is fixedly installed in the middle of the outer side of the cleaning ring 15. A middle collar 19 is fixedly installed in the outer side of the fixing block 14. The upper surface of the middle collar 19 is provided with an inward groove ring. The diameter of the groove ring is larger than the diameter of the feed pipe 18. The groove ring is located in the outer side of the middle collar 19 to prevent liquid from flowing out to the outside when the feed pipe 18 and the discharge pipe 17 are connected. The liquid that flows out is collected by the groove ring. The bottom of the inner wall of the groove ring is horizontal with the feed hole in the middle of the feed pipe 18. The feed hole returns the collected liquid to the inside of the feed pipe 18, reducing the waste of resources. A limiting rod 20 is slidably inserted in the middle of the middle end of the middle collar 19 away from the rectangular toothed plate 12. The bottom of the limiting rod 20 is fixedly installed in the upper surface of the base plate 1. The limiting rod 20 restricts the movement trajectory of the middle collar 19.
[0026] Please see Figure 1 and Figure 2 A rectangular toothed plate 12 is fixedly installed on the middle of one side of the outer circumference of the central collar 19 via a connecting rod. Vertical rods 9 are slidably inserted into the top and bottom of the rectangular toothed plate 12. The vertical rods 9 are set at both ends of the rectangular toothed plate 12. Under the action of the vertical rods 9, the rectangular toothed plate 12 is kept in a vertical state during movement. The end of the vertical rod 9 away from the rectangular toothed plate 12 is fixedly installed at the bottom of the base plate 1 and the top liquid tank 16, respectively. Teeth are provided on both sides of the rectangular toothed plate 12. The teeth on both sides of the rectangular toothed plate 12 engage with two fan-shaped toothed plates 13 in sequence. The outer teeth of the two fan-shaped toothed plates 13 are set in the same opposite direction. The two fan-shaped toothed plates 13 are set in the same direction to ensure that they engage with the rectangular toothed plate 12 in sequence after the two fan-shaped toothed plates 13 move one revolution, so that the rectangular toothed plate 12 can move up and down reciprocally.
[0027] Please see Figure 1 A rectangular toothed plate 12 is provided with a fan-shaped toothed plate 13 through the meshing of the outer teeth. A rotating shaft 8 is fixedly inserted into the middle of the end of the fan-shaped toothed plate 13 away from the rectangular toothed plate 12. A third pulley 7 is fixedly sleeved on the outer circumferential surface of the middle of the rotating shaft 8. There are two third pulleys 7. The middle of the outer sides of the two third pulleys 7 are connected by belt drive. The middle of the two third pulleys 7 are rotatably set at both ends of one side of the transverse plate 11 through the rotating shaft 8. A fan-shaped toothed plate 13 is sleeved on one end of the rotating shaft 8. Under the action of the second pulley 6, the two third pulleys 7 drive the two fan-shaped toothed plates 13 on one side to rotate simultaneously. A transverse plate 11 is rotatably sleeved on the end of the rotating shaft 8 away from the fan-shaped toothed plate 13. A support plate 10 is fixedly set in the middle of the transverse plate 11. The bottom of the support plate 10 is fixedly set at one end of the upper surface of the base plate 1.
[0028] Please see Figure 2 A second pulley 6 is fixedly sleeved on the outer circumferential surface of the rotating shaft 8 near the transverse plate 11. A first pulley 3 is driven by a belt strip 5 at the middle of the outer circumferential surface of the second pulley 6. The middle of the first pulley 3 is fixedly sleeved on the outer circumferential surface of the output shaft on one side of the motor 4. The bottom of the motor 4 is fixedly installed at one end of the upper surface of the base plate 1.
[0029] Please see Figure 1 and Figure 4 The top of the detector body 2 is fixedly equipped with a top liquid tank 16. Discharge pipes 17 are evenly arranged at the bottom of the top liquid tank 16. The top of the discharge pipes 17 communicates with the bottom of the bottom liquid tank. A fixed inner plate 23 is fixedly installed in the middle of the inner wall of the discharge pipes 17. A blocking plate 22 is fixedly installed at the bottom of the fixed inner plate 23 by a spring. A bottom limiting ring 21 is slidably installed at the bottom of the blocking plate 22. A discharge hole is provided in the middle of the bottom limiting ring 21. The diameter of the ring is the same as the diameter of the feed pipe 18. The diameter of the inner ring of the bottom limiting ring 21 is smaller than the diameter of the block plate 22. After the feed pipe 18 moves upward a certain distance, it is inserted into the interior of the bottom limiting ring 21. The top of the feed pipe 18 pushes the block plate 22 upward, thereby opening the bottom of the discharge pipe 17, allowing the liquid inside the top liquid tank 16 to flow out through the discharge pipe 17 into the interior of the feed pipe 18. The outer side of the bottom limiting ring 21 is fixedly set at the bottom of the inner wall of the discharge pipe 17.
[0030] The implementation principle of an automatically cleanable hydrogen detector according to this application embodiment is as follows: During use, when dust accumulates on the outer wall of the hydrogen detector after a period of use, cleaning liquid is poured into the top liquid tank 16. The motor 4 is started as power, and the rotating shaft 8 rotates under the action of the belt 5 via the first pulley 3 and the second pulley 6. The rotating shaft 8, under the action of the third pulley 7, causes the two fan-shaped toothed plates 13 to rotate simultaneously. Since the teeth on one side of the two fan-shaped toothed plates 13 are aligned, when the right fan-shaped toothed plate 13 meshes with the central rectangular toothed plate 12, the rectangular toothed plate 12 moves upward. After the right fan-shaped toothed plate 13 has rotated half a revolution, it disengages from the central rectangular toothed plate 12, and the left fan-shaped toothed plate 13... The edge teeth rotate to the left tooth position of the rectangular toothed plate 12 and mesh with it. At this time, the fan-shaped toothed plate 13 continues to rotate, and the rectangular toothed plate 12 moves downward under the force. Under the action of the two fan-shaped toothed plates 13, the rectangular toothed plate 12 drives the middle collar 19 on one side to move up and down reciprocally. When the middle collar 19 moves upward a certain distance, the feed pipe 18 in the middle is inserted into the inside of the discharge pipe 17. At the same time, the bottom of the block plate 22 on the inner wall of the discharge pipe 17 is pushed upward, thereby opening the bottom of the discharge pipe 17, so that the liquid inside flows into the inside of the feed pipe 18, and flows into the inside of the cleaning ring 15. When the cleaning ring 15 moves up and down reciprocally, it cleans the surface of the hydrogen detector, reducing manual interference during the cleaning process.
[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
