[0003] Existing automatic gas pipeline detection and alarm devices need to be installed at high locations. However, when these devices need calibration, workers have to climb ladders to reach them, which not only increases the difficulty and danger of the work but also greatly reduces work efficiency. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide an automatic detection and alarm device for gas pipelines, so as to solve the technical problem that alarm devices installed at high locations need to be climbed up and taken down when calibration is required.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic detection and alarm device for gas pipelines, comprising a sensor, a sliding block fixedly connected to one side of the sensor, an upper mounting block provided on the outer side of the sliding block, an upper patch fixedly connected to one side of the upper mounting block, an upper rotating wheel rotatably connected to one side of the upper mounting block, a lower mounting block provided below the upper mounting block, a lower rotating wheel rotatably connected to one side of the lower mounting block, a first pull rope sleeved on the outer side of the lower rotating wheel and the upper rotating wheel, the first pull rope being fixedly connected to the sliding block, and a lower patch fixedly connected to the other side of the lower mounting block.

[0006] By adopting the above technical solution, the sensor can be easily fixed in the required position by the cooperation of the sliding block with the upper and lower mounting blocks.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure. Example

[0030] An automatic detection and alarm device for gas pipelines, such as Figures 1-5As shown, the device includes a sensor 1. A sliding block 2 is fixedly connected to one side of the sensor 1. An upper mounting block 3 is provided on the outside of the sliding block 2. An upper patch 4 is fixedly connected to one side of the upper mounting block 3. An upper rotating wheel 5 is rotatably connected to one side of the upper mounting block 3. A lower mounting block 6 is provided below the upper mounting block 3. A lower rotating wheel 7 is rotatably connected to one side of the lower mounting block 6. A first pull rope 8 is sleeved on the outside of the lower rotating wheel 7 and the upper rotating wheel 5. The first pull rope 8 is fixedly connected to the sliding block 2. A lower patch 10 is fixedly connected to the other side of the lower mounting block 6. The sensor 1 can be easily fixed in the required position by the cooperation of the sliding block 2 with the upper mounting block 3 and the lower mounting block 6. Through the ingenious combination of the upper rotating wheel 5, the lower rotating wheel 7 and the first pull rope 8, the sensor 1 can be easily removed without the aid of external tools and without climbing, reducing the safety risks for staff during the calibration process. In addition, the use of the upper patch 4 and the lower patch 10 also increases the stability of the device installation, ensuring the accuracy and stability of the sensor 1 during the detection process.

[0031] See Figure 4 A locking block 9 is provided between the sliding block 2 and the upper mounting block 3. The locking block 9 is made of rubber. By setting the locking block 9 between the sliding block 2 and the upper mounting block 3, a more stable fixing effect is achieved. The locking block 9 can effectively lock the sliding block 2 and prevent it from accidentally falling off due to external force or vibration, thereby ensuring that the sensor 1 can be stably installed in the predetermined position. At the same time, the locking block 9 is made of rubber, which has good elasticity and wear resistance. It can not only enhance the friction between the locking block 9 and the sliding block 2 and improve the fixing effect, but also reduce the noise generated by the device during operation to a certain extent.

[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 4 A corrugated tube 11 is fitted on the outer side of the first pull rope 8, and a plug 12 is fixedly connected to the bottom of the sensor 1. The corrugated tube 11 can effectively prevent the first pull rope 8 from being directly exposed to the external environment, thereby reducing the corrosion of the pull rope by pollutants such as oil and dust, keeping it clean and durable, ensuring the smooth movement of the first pull rope 8, extending its service life, and reducing maintenance costs. At the same time, the plug 12 can be easily inserted into or removed from the socket, thereby realizing the power supply of the sensor 1 and ensuring that the sensor 1 can work reliably.

[0033] The implementation principle of this utility model is as follows: First, the upper mounting block 3 is attached to the installation position using the upper patch 4, and then the lower mounting block 6 is attached to the designated position using the lower patch 10 to complete the installation;

[0034] When sensor 1 needs to be removed for calibration, rotate the lower wheel 7. The lower wheel 7 drives the first pull rope 8 to move, which in turn pulls the sliding block 2, so that the sliding block 2 and the locking block 9 are unlocked. As the first pull rope 8 moves, the sliding block 2 reaches the bottom and then calibrates the sensor 1. After that, rotate the lower wheel 7 in the opposite direction so that the first pull rope 8 can pull the sliding block 2 upward, so that the sliding block 2 can re-enter the interior of the upper mounting block 3 and be locked by the locking block 9, thus achieving a reset.

[0035] The corrugated tube 11 on the outer side of the first pull rope 8 serves to prevent oil stains from getting on the surface of the pull rope 8. Example

[0036] See Figure 5 A second pull rope 13 is fitted on the outer side of the lower rotating wheel 7 and the upper rotating wheel 5. One end of the second pull rope 13 is fixedly connected to a rack 14. By fitting the second pull rope 13 on the outer side of the lower rotating wheel 7 and the upper rotating wheel 5 and fixing the rack 14 to one end of the second pull rope 13, an additional adjustment and fixing mechanism is provided for the gas pipeline automatic detection alarm device, making the device more reliable during installation. At the same time, the rack 14 can cooperate with the gear mechanism that may be equipped later to achieve fine adjustment and locking functions, ensuring that the second pull rope 13 can reliably pull down the sensor 1.

[0037] See Figure 5 A collar 15 is fixedly connected to one side of the other end of the second pull rope 13, and a connecting rod 16 is fixedly connected to the other side of the other end of the second pull rope 13. By fixing the collar 15 to one side of the other end of the second pull rope 13, a sliding path is provided for the rack 14, so that the rack 14 can slide stably and ensure the accuracy of the movement of the rack 14. At the same time, the connecting rod 16 can act as a support, allowing the user to more conveniently adjust the tension of the second pull rope 13, thereby adjusting the overall state of the second pull rope 13.

[0038] See Figure 5 A gear 17 is rotatably connected to the top of the connecting rod 16, and a spring sleeve rod 18 is fixedly connected to one side of the connecting rod 16. The gear 17 rotatably connected to the top of the connecting rod 16 provides a precise adjustment mechanism for the device. Through cooperation with the rack 14, the gear 17 can finely adjust the length and tension of the second pull rope 13, thereby ensuring that the sensor 1 can be reliably pulled down. At the same time, the extensibility of the spring sleeve rod 18 also enables the gear 17 to maintain a stable lock, thereby maintaining the stability of the sensor 1 and enhancing the adaptability and reliability of the device.

[0039] See Figure 5One end of the spring sleeve rod 18 is fixedly connected to a locking plate 19, which is slidably connected to the connecting rod 16. The locking plate 19, which is fixedly connected to one end of the spring sleeve rod 18, provides a practical locking mechanism for the device. Through the slidable connection between the locking plate 19 and the connecting rod 16, the connecting rod 16 can be easily fixed or released, thereby locking or unlocking the position of the gear 17. This ensures that the device remains stable during use and prevents displacement or failure due to misoperation or external interference. At the same time, the slidable connection between the locking plate 19 and the connecting rod 16 also makes locking and unlocking operations simple and quick. Users only need to slide the locking plate 19 to complete the locking or unlocking without using additional tools, which improves the convenience of operation.

[0040] The implementation principle of this utility model is as follows: First, when the second pull rope 13 becomes loose, press the locking plate 19 to unlock the gear 17, move the gear 17, and the gear 17 moves the rack 14 along the collar 15 to tighten the second pull rope 13. Finally, release the locking plate 19, the locking plate 19 locks the gear 17, and the second pull rope 13 is released.

[0041] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0042] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
