[0002] A natural gas burner is a device for igniting natural gas. It is part of a split-type combustion device. Its function is to mix natural gas and air in a certain proportion and ignite it to make it burn.

[0003] Due to the flammable and explosive nature of natural gas, it is essential to perform rigorous leak detection during use. This necessitates the use of natural gas valve leak detectors. Existing natural gas valve leak detectors are typically installed on natural gas pipelines and secured with pipe clamps. However, since pipeline diameters vary, this necessitates frequent replacement of pipe clamps, which is highly inconvenient. Therefore, a natural gas valve leak detector capable of being adapted to pipes of different diameters is needed to solve this problem. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1 - Figure 4 The specific embodiments of this utility model will be described in further detail.

[0023] Depend on Figure 1 - Figure 4 As shown, the detector 1 and fixing block 2 of this utility model are designed to facilitate the fixing of pipes of different diameters. The fixing block 2 is fixedly connected to the rear side of the detector 1. A fixing sleeve 3 is fixedly connected to the left rear part of the fixing block 2, and an arc-shaped plate 4 is fixedly connected to the right rear part of the fixing block 2. A first clamping block 5 is fixedly connected to the right end of the arc-shaped plate 4. A sliding plate 6 is slidably connected inside the fixing sleeve 3, and a second clamping block 7 is fixedly connected to the left side of the sliding plate 6. A circular hole 8 is opened in the middle of both the first clamping block 5 and the second clamping block 7. The first clamping block 5 and the second clamping block 7 cooperate with each other to form a fixed structure of the device.

[0024] It should be noted that the detector 1 is a natural gas leak detector, which is existing technology, such as the WL-1000 / 2000 natural gas leak detector, and will not be described in detail here; the fixed sleeve 3 and the sliding plate 6 are both made of plastic, which is elastic and can undergo a certain degree of elastic deformation.

[0025] In use, the fixing sleeve 3 can be passed through the natural gas transmission pipe and then fixed with bolts through the circular hole 8 between the first clamping block 5 and the second clamping block 7. When the transmission pipe to be matched is thicker, the second clamping block 7 can be pulled. At this time, under the action of the sliding plate 6, the second clamping block 7 will move away from the fixing sleeve 3, thus being able to adapt to a thicker transmission pipe.

[0026] Furthermore, by Figure 1 - Figure 4 As shown, in order to facilitate the retraction of the second clamping block 7, a steel wire rope 9 is fixedly connected to the side of the sliding plate 6 away from the second clamping block 7. A turntable 10 is rotatably connected inside the fixed block 2. The steel wire rope 9 is wound around the middle of the turntable 10 and the other end of the steel wire rope 9 is rotatably connected to the turntable 10. A spring 11 is provided on the rear side of the turntable 10. The spring 11 and the turntable 10 cooperate with each other to form a structure in which the steel wire rope 9 automatically retracts.

[0027] When in use, when the second clamping block 7 is pulled, the second clamping block 7 will pull the wire rope 9 through the sliding plate 6. At this time, the wire rope 9 will drive the turntable 10 to rotate, thereby causing the spring 11 to store power. When the second clamping block 7 is released, the wire rope 9 will be in a tighter state under the action of the spring 11.

[0028] Furthermore, by Figure 1 - Figure 4 As shown, the two ends of the spring 11 are respectively fixedly connected to a first fixing post 12 and a second fixing post 13. The first fixing post 12 is rotatably connected to the rear side of the turntable 10, and the second fixing post 13 is rotatably connected to the interior of the fixing block 2.

[0029] In use, the first fixing post 12 and the second fixing post 13 enable the spring 11 to charge more smoothly.

[0030] Furthermore, by Figure 1 - Figure 4 As shown, to facilitate operation by staff, an inner ratchet 14 is fixedly connected inside the turntable 10. An adjusting plate 15 is concentrically arranged on the inner side of the inner ratchet 14. The adjusting plate 15 is rotatably connected to the inside of the fixed block 2. Two pawls 16 that are adapted to the inner ratchet 14 are rotatably connected to the rear side of the adjusting plate 15. Two mounting posts 17 are fixedly connected to the rear side of the adjusting plate 15. A spring 18 is fixedly connected to each mounting post 17. The other end of each spring 18 abuts against the corresponding pawl 16.

[0031] Furthermore, by Figure 1 - Figure 4 As shown, the adjustment plate 15 has two adjustment slots 19, and an adjustment block 20 is slidably connected inside each adjustment slot 19. A rotatable adjustment frame 21 is provided on the front side of the adjustment plate 15, and the front side of each adjustment block 20 is fixedly connected to the adjustment frame 21.

[0032] In use, when the turntable 10 rotates, the adjusting frame 21 and the adjusting block 20 cannot rotate. Therefore, the adjusting disc 15 is in a floating rotating state, with a rotation stroke equal to the length of the adjusting groove 19. Under the action of the spring 18, the pawl 16 remains tightly against the inner ratchet 14. As the wire rope 9 pulls the turntable 10, the inner ratchet 14 slides relative to the pawl 16, allowing the turntable 10 to rotate and release the wire rope 9. After the second clamping block 7 has been pulled out to a suitable distance, the turntable 10 can be rotated by rotating the adjusting frame 21. The reverse rotation pulls the wire rope 9 to tighten it. At this time, the adjusting frame 21 drives each adjusting block 20 to approach the corresponding pawl 16. When the adjusting block 20 moves to the end of the adjusting groove 19, the adjusting block 20 will limit the corresponding pawl 16, so that the pawl 16 cannot retract inward. As the adjusting frame 21 continues to rotate, the rotational power of the adjusting frame 21 drives the inner ratchet 14 to rotate through the adjusting block 20, the adjusting groove 19 and the pawl 16, which in turn drives the turntable 10 to rotate, thus tightening the wire rope 9.

[0033] Furthermore, by Figure 1 - Figure 4 As shown, in order to tighten and fix the wire rope 9, a worm gear 22 is fixedly connected to the front side of the adjusting frame 21, a worm 23 is engaged on the lower side of the worm gear 22, and an adjusting rod 24 is fixedly connected to the right side of the worm 23. The end of the adjusting rod 24 has an internal hexagonal groove for easy rotation. A vertical plate 25 is fixedly connected to the rear side of the fixing block 2, and multiple anti-slip protrusions 26 are fixedly connected to the rear side of the vertical plate 25. The anti-slip protrusions 26 are made of rubber and have a large friction force.

[0034] In use, by rotating the adjusting rod 24, the worm gear 23 drives the worm wheel 22 to rotate, which in turn drives the adjusting frame 21 to rotate. Under the self-locking action of the worm wheel 22 and the worm gear 23, the position of the sliding plate 6 relative to the fixed sleeve 3 is kept fixed.

[0035] The vertical plate 25 increases the contact area between the fixing block 2 and the natural gas pipeline, and the anti-slip protrusion 26 reduces the risk of the entire device sliding down.

[0036] When using this utility model, the fixing sleeve 3 can first be passed through the natural gas transmission pipe, and then fixed by bolts through the circular hole 8 between the first clamping block 5 and the second clamping block 7. When the transmission pipe to be matched is thicker, the second clamping block 7 can be pulled. At this time, under the action of the sliding plate 6, the second clamping block 7 will move away from the fixing sleeve 3, thus being able to adapt to a thicker transmission pipe.

[0037] When the second clamping block 7 is pulled, it pulls the wire rope 9 through the sliding plate 6. The wire rope 9 then drives the turntable 10 to rotate. While the turntable 10 is rotating, the adjusting frame 21 and the adjusting block 20 cannot rotate. Therefore, the adjusting disc 15 is in a floating rotating state, with a rotation stroke equal to the length of the adjusting groove 19. Under the action of the spring 18, the pawl 16 remains firmly against the inner ratchet 14. During the process of the wire rope 9 pulling the turntable 10, the inner ratchet 14 slides relative to the pawl 16, allowing the turntable 10 to rotate and release the wire rope 9. After the second clamping block 7 has been pulled out to a suitable distance, the turntable 10 can be rotated in the opposite direction by rotating the adjusting frame 21. At this time, by rotating the adjusting rod 24... The worm gear 23 drives the worm wheel 22 to rotate, which in turn drives the adjusting frame 21 to rotate, pulling the wire rope 9 to tighten. At this time, the adjusting frame 21 drives each adjusting block 20 to approach the corresponding pawl 16. When the adjusting block 20 moves to the end of the adjusting groove 19, the adjusting block 20 will limit the corresponding pawl 16, preventing the pawl 16 from retracting inward. As the adjusting frame 21 continues to rotate, the rotational power of the adjusting frame 21 drives the inner ratchet 14 to rotate through the adjusting block 20, adjusting groove 19 and pawl 16, which in turn drives the turntable 10 to rotate, tightening the wire rope 9. Under the self-locking action of the worm wheel 22 and worm gear 23, the position of the sliding plate 6 relative to the fixed sleeve 3 remains fixed.

[0038] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively achieves the purpose of conveniently fixing pipes of different diameters, which facilitates the operation of the staff, allows the steel wire rope 9 to be tightened and fixed, and increases the stability of the fixation between the device and the natural gas transmission pipe.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
