Description

Technical Field

[0001] This utility model relates to the field of hydrogen leak sensor technology, and in particular to a hydrogen leak sensor with an audible and visual alarm structure. Background Technology

[0002] Hydrogen energy, as a clean and efficient new energy source, is increasingly being applied in industrial upgrading. However, hydrogen is colorless, odorless, flammable, explosive, and diffuses rapidly. Leaks can easily cause safety accidents. Traditional monitoring methods are not timely enough to provide warnings. Therefore, hydrogen leak sensors with audible and visual alarm structures have become an important requirement for safety assurance. The core applications of this sensor are in industries involving the use and circulation of hydrogen, such as hydrogen vehicle manufacturing and maintenance, fuel cell production workshops, hydrogen preparation and storage sites, and chemical synthesis plants. It is also widely used in scientific research laboratories and other scenarios. The hydrogen leak sensor with an audible and visual alarm structure comprises a hydrogen sensing unit, a signal conversion and processing module, an audible and visual alarm execution module, and a power supply and communication module. The sensing unit captures the hydrogen concentration signal in the environment in real time. After analysis and judgment by the processing module, if the concentration reaches a preset threshold, the alarm module immediately activates and emits a continuous buzzing sound, accompanied by flashing red high-brightness LEDs. The main function of this sensor is to achieve real-time monitoring and rapid early warning of hydrogen leaks. Through dual audible and visual warnings, it ensures that on-site personnel can detect dangers in complex environments at the first moment, buying valuable time for emergency response and reducing the safety risks of explosions, fires, etc. caused by hydrogen leaks from the source, thus protecting the safety of production, life, and personnel and property. Existing hydrogen leak sensor technologies have many shortcomings. The fixing structure mostly uses traditional methods such as bolt fastening, which requires tools for installation and disassembly and is cumbersome. Some lack a reliable elastic reset mechanism, which is prone to loosening after long-term use, leading to a decrease in monitoring stability. The flip-top structure often relies on manual opening and closing, which is inconvenient to operate at heights or in confined spaces, thus affecting the accuracy of monitoring and the timeliness of alarms. Therefore, a hydrogen leak sensor with an audible and visual alarm structure is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a hydrogen leak sensor with an audible and visual alarm structure, aiming to improve the problem of cumbersome operation during installation and disassembly in the prior art.

[0014] 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.

[0015] Reference Figures 1-4 An embodiment of this utility model provides a hydrogen leak sensor with an audible and visual alarm structure, comprising a body 1, a connecting line 5 fixedly connected to the bottom of the body 1, a hydrogen sensor 3 fixedly connected to the end of the connecting line 5 away from the body 1, a warning light 4 fixedly connected to one side of the hydrogen sensor 3, a connecting block 7 fixedly connected to the rear side of the body 1, a fixing block 6 slidably connected to the outer side of the connecting block 7, a spring 15 provided on the inner side of the fixing block 6, a pressing pin 13 slidably connected to the inner side of the fixing block 6, a locking block 19 fixedly connected to the bottom of the pressing pin 13, and a handle 14 fixedly connected to one end of the pressing pin 13.

[0016] The connecting line 5 is used to realize signal transmission and power supply between the body 1 and the hydrogen sensor 3. The hydrogen sensor 3 collects hydrogen concentration information in the surrounding environment in real time. When hydrogen leakage is detected, the warning light 4 will be triggered. At the same time, the handle 14 can be used to control the pressing pin 13 to slide along the inside of the fixing block 6. With the elastic action of the spring 15, the locking block 19 can be driven to adjust its position. The sliding cooperation between the connecting block 7 and the fixing block 6 provides the basic structural conditions for the installation and fixation of the sensor.

[0017] Reference Figure 3 A rotating shaft 9 is rotatably connected to the inner side of the machine body 1, and a cover plate 2 is fixedly connected to the outer side of the rotating shaft 9. A support base 10 is fixedly connected to one side of the machine body 1, and a drive motor 11 is fixedly connected to the top of the support base 10.

[0018] The support base 10 provides a stable mounting support for the drive motor 11, ensuring that the drive motor 11 will not deviate when it is working. After the drive motor 11 is started, it can output power and drive the rotating shaft 9 to rotate around the inside of the machine body 1 through the relevant transmission structure. The rotation of the rotating shaft 9 will synchronously drive the outer fixed cover plate 2 to open or close, thereby realizing the protection and maintenance operation control of the internal structure of the machine body 1.

[0019] Reference Figure 4 One end of the spring 15 is fixedly connected to the inner wall of the fixing block 6, and the other end of the spring 15 is fixedly connected to the outer side of the pressing pin 13.

[0020] The spring 15 connects the pressing pin 13 to the inner wall of the fixing block 6 through the fixed connection at both ends. When the pressing pin 13 is subjected to external force and slides along the inner side of the fixing block 6, the spring 15 will undergo elastic deformation and generate a reverse elastic force. When the external force disappears, the elastic restoring force of the spring 15 will drive the pressing pin 13 to automatically reset, ensuring that the locking block 19 always has a reliable locking force.

[0021] Reference Figure 4 The connecting block 7 has slots 18 on both sides, and the card block 19 is engaged inside the slots 18.

[0022] The slot 18 provides a precise snap-fit ​​positioning structure for the card block 19. When the card block 19 is inserted into the inside of the slot 18 under the action of the pressing pin 13, the connecting block 7 and the fixing block 6 will be fixedly connected as one unit through mechanical snap-fit ​​action, so as to realize the installation and fixation of the sensor. When it is necessary to disassemble, simply drive the card block 19 out of the slot 18 to release the fixed relationship between the two.

[0023] Reference Figure 3 The output end of the drive motor 11 is fixedly connected to the second gear 12, and the end of the rotating shaft 9 away from the cover plate 2 is fixedly connected to the first gear 8. The second gear 12 and the first gear 8 mesh with each other.

[0024] After the drive motor 11 starts, its output end will drive the second gear 12 to rotate synchronously. Since the second gear 12 is meshed with the first gear 8, the rotation of the second gear 12 will drive the first gear 8 to rotate through the transmission between the teeth. The first gear 8 will then drive the rotating shaft 9 fixed to it to rotate, thereby smoothly transmitting the power of the drive motor 11 to the rotating shaft 9 and realizing the mechanical control of the cover plate 2.

[0025] Reference Figure 5 A display screen 16 is provided on one side of the body 1, and a voice control 17 is provided on one side of the body 1.

[0026] The display screen 16 is used to display hydrogen concentration data and sensor working status collected by the hydrogen sensor 3 in real time, which is convenient for operators to monitor intuitively. The sound control 17 is used as the sound warning component of the sound and light alarm system. When the hydrogen sensor 3 detects hydrogen leakage and reaches the alarm threshold, the sound control 17 will be activated to issue a sound alarm at the same time. Together with the light warning of the warning light 4, it forms a dual alarm effect to ensure that the operator can detect the danger in time.

[0027] Working principle: When installation is required, firstly, the handle 14 controls the pressing pin 13 to slide along the inner side of the fixing block 6. The spring 15 inside the fixing block 6 undergoes elastic deformation due to the sliding of the pressing pin 13, causing the locking block 19 to engage with the locking slots 18 on both sides of the connecting block 7. The connecting block 7 and the fixing block 6 are fixed through mechanical engagement, completing the installation and fixing of the machine body 1. After the external force disappears, the elastic restoring force of the spring 15 causes the pressing pin 13 to return to its original position, ensuring that the locking block 19 is locked. The connecting line 5 at the bottom of the machine body 1 transmits power and signals to the hydrogen sensor 3. The hydrogen sensor 3 collects the ambient hydrogen concentration in real time, and the data is transmitted back to the machine body 1 via the connecting line 5. The concentration and sensor working status are displayed in real time on the display screen 16 on one side of the machine body 1. When the hydrogen sensor 3 detects a leak and the concentration reaches the threshold, it immediately triggers the warning light 4 on its side to light up. At the same time, the sound control 17 on the side of the body 1 is activated to emit an audible alarm, forming a dual warning of sound and light. The support base 10 on the side of the body 1 firmly supports the drive motor 11. After the drive motor 11 is started, the output end drives the second gear 12 to rotate. Through gear meshing, the first gear 8 at one end of the rotating shaft 9 is driven to rotate. The rotating shaft 9 then rotates around the inside of the body 1, synchronously driving the outer fixed cover 2 to open or close, realizing the protection and maintenance control of the internal structure of the body 1. The entire process involves the coordinated operation of all components to complete the complete workflow of sensor installation and fixation, concentration monitoring, alarm, and internal protection.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
