Description

Technical Field

[0001] This utility model relates to the technical field of hydrogen generator equipment, specifically to a safety-protected integrated hydrogen generator device. Background Technology

[0002] A hydrogen generator is a device used to produce high-purity hydrogen. It is widely used in analytical instruments such as gas chromatography, mass spectrometry, and atomic absorption spectrometry, and also plays an important role in laboratories, industry, aerospace, and energy fields. Hydrogen generators mainly convert other substances into hydrogen through electrolysis or chemical reactions, and can continuously and reliably produce hydrogen with extremely high purity.

[0003] The prior art provides a hydrogen generator (publication number CN219260211U), including a hydrogen generator body and a measuring cup. A water inlet pipe is fixedly connected to the upper end of the hydrogen generator body, and a flexible hose is fixedly connected to the lower end of the measuring cup, with the flexible hose connected to the water inlet pipe. A vertically arranged support frame is fixedly connected to one side of the hydrogen generator body. A sliding plate is slidably connected to the support frame along the vertical direction. A vertically arranged screw is rotatably connected to the support frame, and the sliding plate is slidably connected to the screw. A support ring is fixedly connected to the upper side of the sliding plate, and the measuring cup is fixedly connected to the support ring. A spring is fixedly connected to the upper end of the support ring, and a cover plate is provided above the support ring. The upper end of the spring is fixedly connected to the lower side of the cover plate. Two vertical rods are fixedly connected to one side of the hydrogen generator body corresponding to the support frame. The vertical rods can pass through the sliding plate, and the upper ends of the two vertical rods can abut against the cover plate. The hydrogen generator provided in this application can avoid spilling pure water when adding pure water to the inlet pipe, thereby improving the efficiency of hydrogen production.

[0004] Based on the above patent search, it is found that the aforementioned patents cannot monitor the internal cylinder in real time during actual use. When the hydrogen generator produces hydrogen, the internal pressure will increase. When the pressure exceeds the safe range that the device can withstand, it may cause dangerous situations such as device rupture and hydrogen leakage, which will pose a serious threat to the operator and the surrounding environment. At the same time, when fixing the overall device, the aforementioned patents require manual rotation of the threaded rod. This fixing method is not only cumbersome to operate, but may also be prone to insecure fixing or loosening due to human factors. Once the device becomes loose or falls off during operation, it may cause more serious safety accidents. Therefore, we need to propose a safety-protected integrated hydrogen generator device. Utility Model Content

[0005] The purpose of this invention is to provide a safety-protected integrated hydrogen generator device. By setting up a monitoring component, a hydrogen pressure sensor monitors the internal gas pressure of the hydrogen generator body in real time. Once the gas pressure exceeds the preset safety range, the monitoring component can be quickly activated, driving the extension end of the cylinder to move the sealing block, thereby opening the exhaust port to exhaust gas, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A safety-protected integrated hydrogen generator device includes a hydrogen generator body, a base fixedly installed at the bottom of the hydrogen generator body, a lifting component inside the base, a cylinder at the top of the hydrogen generator body, and a monitoring component for safely monitoring and adjusting the hydrogen pressure inside the hydrogen generator body.

[0008] The monitoring component includes a cylinder located at the top of the cylinder body, a support frame installed on the top of the hydrogen generator body, the top of the cylinder being fixedly connected to the inner top of the support frame, a hydrogen pressure sensor being installed at the bottom of the cylinder body, a sealing block being fixedly installed at the telescopic end of the cylinder body, and two sets of exhaust holes being opened on the outer side of the cylinder body.

[0009] Preferably, two sets of sliders are installed on the outer side of the sealing block, and two sets of sliding grooves are provided inside the cylinder for the sliders to slide. The two sets of sliders are respectively slidably disposed inside the two sets of sliding grooves.

[0010] Preferably, a connecting frame is installed at the bottom of the cylinder, and the hydrogen pressure sensor is fixedly installed at the bottom of the connecting frame.

[0011] Preferably, an air storage box is installed on the outside of the cylinder, a purification filter is installed inside the air storage box, and multiple sets of air outlets are opened on the top of the air storage box.

[0012] Preferably, the inner wall of the purification filter is fitted to the outer wall of the cylinder, the purification filter is located above the exhaust port, and multiple sets of exhaust ports are arranged in a ring array.

[0013] Preferably, the lifting assembly includes a motor fixedly installed at the bottom of the base. The output end of the motor is fixedly connected to a rotating rod via a coupling. The top end of the rotating rod is rotatably installed at the top of the base. A threaded rod is rotatably installed inside the base.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, through the setting of the monitoring component, uses a hydrogen pressure sensor to monitor the internal gas pressure of the hydrogen generator body in real time. Once the gas pressure exceeds the preset safety range, the hydrogen pressure sensor can quickly send a signal to the controller and start the cylinder. The extension end of the cylinder drives the sealing block to move, thereby opening the exhaust port to release gas. The exhaust port releases excess gas in time, thus effectively preventing equipment damage or safety accidents caused by excessive gas pressure. The setting of two sets of exhaust ports further increases the gas release channels, improves the gas emission efficiency, and makes the gas pressure regulation more rapid and stable, thereby improving the safety performance of the equipment.

[0018] 2. This utility model, through the setting of the lifting component, allows the motor to drive the rotating rod and the driving wheel to rotate when the hydrogen generator body needs to be used. This causes the driving wheel to drive the driven wheel and the threaded rod to rotate through the toothed belt, thereby moving the moving plate on the threaded rod. This achieves smooth lifting and lowering of the moving wheel, and the moving wheel retracts into the base, allowing the base to be placed stably, ensuring the stable operation of the hydrogen generator and further improving the safety of use.

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A safety-protected hydrogen generator integrated device includes a hydrogen generator body 1, a base 2 fixedly installed at the bottom of the hydrogen generator body 1, a lifting component 3 installed inside the base 2, a cylinder 4 installed at the top of the hydrogen generator body 1, and a monitoring component 5 installed inside the cylinder 4 for safely monitoring and adjusting the hydrogen pressure inside the hydrogen generator body 1.

[0027] The monitoring component 5 includes a cylinder 51 located at the top of the cylinder 4, a support frame 52 installed on the top of the hydrogen generator body 1, the top of the cylinder 51 being fixedly connected to the inner top of the support frame 52, a hydrogen pressure sensor 53 located at the bottom of the cylinder 4, a sealing block 54 fixedly installed at the telescopic end of the cylinder 51, and two sets of exhaust holes 55 opened on the outer side of the cylinder 4.

[0028] Two sets of sliders 6 are installed on the outside of the sealing block 54. Two sets of sliding grooves 7 are opened inside the cylinder 4 for the sliders 6 to slide. The two sets of sliders 6 are respectively slidably arranged inside the two sets of sliding grooves 7. Through the arrangement of sliders 6 and sliding grooves 7, the sealing block 54 is guided and stabilized during the movement process, so that the sealing block 54 can move accurately to the predetermined position and effectively regulate the hydrogen pressure inside the hydrogen generator body 1.

[0029] A connecting frame 8 is installed at the bottom of the cylinder 4. The hydrogen pressure sensor 53 is fixedly installed at the bottom of the connecting frame 8. The connecting frame 8 serves as a support, which improves the stability and reliability of the hydrogen pressure sensor 53, thereby ensuring the accuracy of hydrogen pressure monitoring.

[0030] An air storage box 9 is installed on the outside of the cylinder 4. A purification filter screen 10 is installed inside the air storage box 9. Multiple sets of air outlets 11 are opened on the top of the air storage box 9. Through the arrangement of the air storage box 9 and the purification filter screen 10, the gas discharged from the inside of the cylinder 4 can be filtered and purified, effectively removing impurities and harmful substances from the gas and improving the quality of the discharged gas. At the same time, the annular array of multiple sets of air outlets 11 allows the gas to be discharged evenly and quickly, avoiding local high or low air pressure, and further ensuring the safety and stability of the equipment.

[0031] The inner wall of the purification filter 10 is attached to the outer wall of the cylinder 4. The purification filter 10 is located above the exhaust port 55. Multiple sets of exhaust ports 11 are arranged in a ring array. The arrangement of the purification filter 10 ensures the maximization of the filtration effect and prevents unfiltered gas from being discharged directly. At the same time, the purification filter 10 is located above the exhaust port 55, which can filter the gas first and then discharge it, further improving the purification quality of the gas and protecting the cleanliness of the surrounding environment.

[0032] The lifting assembly 3 includes a motor 31 fixedly installed at the bottom of the base 2. The output end of the motor 31 is fixedly connected to a rotating rod 32 via a coupling. The top end of the rotating rod 32 is rotatably installed on the top of the base 2. A threaded rod 33 is rotatably installed inside the base 2. A movable plate 34 is threadedly connected to the outer side of the threaded rod 33. Multiple sets of movable wheels 35 are installed at the bottom of the movable plate 34. A drive wheel 36 is fixedly installed on the outer side of the rotating rod 32, and a driven wheel 37 is fixedly installed on the outer side of the threaded rod 33. The surfaces of the drive wheel 36 and the driven wheel 37 are connected by a toothed belt 38. With the lifting assembly 3, when the hydrogen generator body 1 needs to be used, the motor 31 drives the rotating rod 32 and the drive wheel 36 to rotate, so that the drive wheel 36 drives the driven wheel 37 and the threaded rod 33 to rotate via the toothed belt 38. Thus, the movable plate 34 moves on the threaded rod 33, realizing the smooth lifting and lowering of the movable wheels 35. The movable wheels 35 retract into the base 2, so that the base 2 can be placed stably, ensuring the stable operation of the hydrogen generator and further improving the safety of use.

[0033] Multiple sets of fixing rods 12 are fixedly installed inside the base 2. The movable plate 34 is slidably disposed on the outside of the multiple sets of fixing rods 12. The fixing rods 12 provide a stable sliding track for the movable plate 34, allowing the movable plate 34 to slide smoothly on the outside of the fixing rods 12. At the same time, the fixing rods 12 also play a supporting and fixing role, enhancing the overall structural strength of the base 2.

[0034] The bottom of the base 2 is provided with a through groove 13 for the movement of the caster 35. The movable plate 34 is slidably disposed inside the base 2. The bottom of the base 2 is provided with an anti-slip pad 14. The through groove 13 allows the caster 35 to extend out of the bottom of the base 2 when needed, thereby realizing the movement function of the equipment. In addition, the anti-slip pad 14 at the bottom of the base 2 can increase the friction between the equipment and the ground, prevent the equipment from sliding or tipping over during use, and further improve the safety and stability of the equipment.

[0035] Working principle: When this utility model is in use, the motor 31 drives the rotating rod 32 and the driving wheel 36 to rotate, which in turn drives the driven wheel 37 and the threaded rod 33 to rotate through the toothed belt 38. As a result, the moving plate 34 moves on the threaded rod 33, realizing the lifting and lowering control of the moving wheel 35. When the moving wheel 35 is retracted into the base 2, the base 2 can be placed stably. The anti-slip pad 14 at the bottom of the base 2 forms a certain friction with the ground, preventing the equipment from sliding or tipping over during use, thus improving the stability and safety of the equipment. At the same time, the hydrogen pressure sensor 53 monitors the hydrogen pressure inside the hydrogen generator body 1 in real time. When the pressure exceeds the set value, the hydrogen pressure sensor 53 can quickly send a signal to the controller and start the cylinder 51. The telescopic end of the cylinder 51 drives the sealing block 54 to move upward, thereby opening the exhaust port 55 to exhaust gas. The exhaust port 55 releases excess gas in time, thus effectively preventing equipment damage or safety accidents caused by excessive gas pressure. The gas storage box 9 and the purification filter 10 can purify the exhaust gas, reducing pollution to the external environment.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
