Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen detection, and specifically provides a hydrogen generator with a self-checking function for hydrogen leakage. Background Art

[0002] As a clean energy source, hydrogen has been widely used in many fields such as fuel cells, chemical production, and scientific research experiments. During the use of hydrogen, the safety issues caused by hydrogen leakage cannot be ignored. Hydrogen has the characteristics of being flammable and explosive. Once it leaks and reaches a certain concentration in the air, it is extremely easy to cause an explosion or fire when encountering an open flame or static electricity, seriously threatening the safety of personnel and property. Therefore, the safety of hydrogen generation equipment has become a key consideration factor, especially the function of hydrogen leakage detection and prevention is crucial.

[0003] In the prior art, traditional hydrogen generators generally have certain defects: on the one hand, the accuracy of hydrogen leakage detection is insufficient. The detection devices equipped in many hydrogen generators have poor sensitivity and are difficult to quickly and accurately detect subtle hydrogen leakage situations. This results in the inability to issue an alarm in a timely manner at the initial stage of hydrogen leakage, causing potential safety hazards to accumulate continuously. Once the leakage situation deteriorates, serious accidents are extremely likely to occur; on the other hand, the response mechanism for hydrogen leakage is also not perfect. Even if some hydrogen generators detect hydrogen leakage, they can only issue a simple alarm, but cannot take targeted measures according to the severity of the leakage, such as being unable to automatically adjust the ventilation volume to reasonably control the hydrogen concentration, nor can they cut off the hydrogen supply source in a timely manner, which greatly limits the effective control of the danger of hydrogen leakage and is difficult to ensure the safety and stability of equipment operation; in addition, existing hydrogen generators also have shortcomings in monitoring the operating state of the equipment. Their real-time monitoring ability for key parameters such as temperature and pressure during the electrolysis process is weak, and abnormal parameters cannot be detected in a timely manner. This may lead to unstable electrolysis processes, not only affecting the production efficiency and quality of hydrogen, but also increasing the probability of equipment failures, shortening the service life of the equipment, and increasing the use cost.

[0004] In view of this, the purpose of the present invention is to provide a hydrogen generator with a self-checking function for hydrogen leakage to solve the deficiencies existing in the prior art. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a hydrogen generator with a self-checking function for hydrogen leakage, which solves the problem of insufficient accuracy in hydrogen leakage detection of traditional devices.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A hydrogen generator with a hydrogen leakage self-checking function, including a box body, a blower is fixedly installed around the outside of the box body, one end of each of the multiple blowers is connected to the inside of the box body, a hydrogen generation mechanism is fixedly installed inside the box body, the hydrogen generation mechanism includes an air outlet assembly, an auxiliary assembly and a filtering and cooling assembly, which are used for detecting and filtering and cooling the generated hydrogen, an adjustment and alarm mechanism is arranged on the inner periphery and the outer top of the box body, the adjustment and alarm mechanism includes an adjustment assembly and an alarm assembly, which are used for adjusting the amount of hydrogen discharged, a hydrogen sensor is fixedly installed at the top end inside the box body, and an observation window is arranged on one side of the box body exterior;

[0007] The adjustment assembly in the adjustment and alarm mechanism includes two fixed blocks fixedly installed on one side inside the box body, adjustment grooves are opened on one side of each of the two fixed blocks, a baffle is slidably connected between the two adjustment grooves, a telescopic rod is fixedly installed on one side inside the box body, and the output end of the telescopic rod is fixedly connected to one side of the baffle.

[0008] Preferably, the alarm assembly includes an alarm one fixedly installed at the top end outside the box body, an alarm two is fixedly installed beside the alarm one, and an alarm three is fixedly installed beside the alarm two.

[0009] Preferably, the alarm levels of the multiple alarms are different.

[0010] Preferably, the air outlet assembly in the hydrogen generation mechanism includes an electrolytic cell fixedly installed inside the box body, an air outlet channel is fixedly installed at the top end inside the electrolytic cell, and a valve is fixedly connected to the outer wall of the air outlet channel.

[0011] Preferably, the auxiliary assembly includes a temperature sensor fixedly installed on one side at the top end outside the electrolytic cell, and a pressure sensor is fixedly installed on the other side at the top end outside the electrolytic cell.

[0012] Preferably, the filtering and cooling assembly includes a filter screen fixedly installed above the electrolytic cell, an outer frame is fixedly installed at the top end of the electrolytic cell, and a plurality of cooling fans are arranged on the inner periphery of the outer frame.

[0013] Preferably, the filter screen is arranged above the outlet end of the air outlet channel.

[0014] Preferably, the baffle is arranged at one end of the blower, and an adjustment assembly is arranged at one end of each of the multiple blowers.

[0017] The present invention provides a hydrogen generator with a hydrogen leakage self-check function. It has the following beneficial effects:

[0018] 1. By coordinating the alarm mechanism and the hydrogen sensor, the present invention realizes precise detection and graded alarm of hydrogen leakage. The hydrogen sensor continuously monitors the hydrogen concentration inside the box. Once leakage occurs, according to the amount of leakage, the control panel controls the telescopic rod to push the baffle to adjust the ventilation volume of the fan, and triggers alarms with different alarm levels, enabling the operator to promptly understand the severity of the leakage situation and take corresponding measures. In the initial stage of leakage, a lower alarm level and appropriately adjusted ventilation volume can not only remind the operator but also avoid unnecessary troubles caused by overreaction. In case of severe leakage, strong alarms and stopping the ventilation operation can maximize the safety of personnel and equipment, effectively reducing the safety risks brought by hydrogen leakage.

[0019] 2. The present invention can effectively filter impurities in hydrogen through the filter screen and cool the hydrogen through the cooling fan. After such treatment, the output hydrogen has higher purity and a more suitable temperature for subsequent use. High-purity hydrogen can meet application scenarios with strict requirements for hydrogen quality, avoiding the influence of impurities on experimental results or product quality. Hydrogen at a suitable temperature reduces the thermal shock to the equipment in use, extends the service life of the equipment, and improves the performance and stability of the entire hydrogen use system.

[0020] 3. By installing a temperature sensor and a pressure sensor in the hydrogen generation mechanism, the present invention continuously monitors the temperature and pressure of the electrolytic cell and transmits the data to the control panel. Once the temperature or pressure is abnormal, the control panel will promptly adjust the working power of the electrolytic cell, ensuring the safety and stability of the electrolysis process, effectively avoiding equipment failures or safety accidents caused by abnormal temperature and pressure, ensuring that the hydrogen generator can operate stably for a long time, reducing equipment maintenance costs and downtime, and improving the continuity and reliability of production.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to the attached Figure 1 - attached Figure 6 The embodiments of the present invention provide a hydrogen generator with a hydrogen leakage self-checking function, including a box body 1. Fans 2 are fixedly installed on the outer periphery of the box body 1. One ends of multiple fans 2 are all connected to the inside of the box body 1. A hydrogen generation mechanism 3 is fixedly installed inside the box body 1. The hydrogen generation mechanism 3 includes a gas outlet component, an auxiliary component, and a filtering and cooling component, which are used for detecting and filtering and cooling the generated hydrogen. Adjustment and alarm mechanisms 4 are provided on the inner periphery and the outer top of the box body 1. The adjustment and alarm mechanism 4 includes an adjustment component and an alarm component, which are used for adjusting the amount of discharged hydrogen. A hydrogen sensor 5 is fixedly installed at the top inside the box body 1. An observation window 6 is provided on one side of the box body 1;

[0030] The adjustment component in the adjustment and alarm mechanism 4 includes two fixed blocks 401 fixedly installed on one side inside the box body 1. Adjustment grooves 402 are opened on one side of the two fixed blocks 401. A baffle 403 is slidably connected between the two adjustment grooves 402. A telescopic rod 404 is fixedly installed on one side inside the box body 1. The output end of the telescopic rod 404 is fixedly connected to one side of the baffle 403;

[0031] The baffle 403 is arranged at one end of the fan 2, and adjustment components are arranged at one ends of multiple fans 2;

[0032] Specifically, the adjustment component in the alarm mechanism 4 includes two fixed blocks 401 fixedly installed on one side inside the box body 1. The two fixed blocks 401 provide a stable track for the sliding of the baffle 403. Adjustment grooves 402 are provided on one side of each of the two fixed blocks 401, ensuring that the baffle 403 can slide smoothly therein. A baffle 403 is slidably connected between the two adjustment grooves 402. The movement of the baffle 403 can effectively control the opening and closing degree of the ventilation opening of the fan 2. A telescopic rod 404 is fixedly installed on one side inside the box body 1. The output end of the telescopic rod 404 is fixedly connected to one side of the baffle 403. Through the telescopic movement of the telescopic rod 404, the baffle 403 can be accurately pushed to slide in the adjustment groove 402, thereby realizing the precise adjustment of the ventilation volume of the fan 2.

[0033] The alarm component includes an alarm one 405 fixedly installed on the top end outside the box body 1. An alarm two 406 is fixedly installed beside the alarm one 405, and an alarm three 407 is fixedly installed beside the alarm two 406;

[0034] The alarm levels of multiple alarms are different;

[0035] Specifically, the alarm component includes an alarm one 405 fixedly installed on the top end outside the box body 1. The alarm one 405 usually adopts an alarm method combining sound and light. When the hydrogen leakage amount is small, it will emit a relatively soft sound alarm and flash lights with a lower frequency, reminding the operator to pay attention to the possible slight hydrogen leakage situation. As the hydrogen leakage amount increases and the hydrogen concentration continues to rise, the control panel 7 will further control the telescopic rod 404 to make the baffle 403 further block the ventilation opening of the fan 2, reducing the ventilation volume. At the same time, it triggers the alarm two 406 with a higher alarm level, attracting the operator's high attention. If the hydrogen leakage situation is serious and the hydrogen concentration reaches the dangerous threshold, the control panel 7 will control the telescopic rod 404 to completely block the ventilation opening of the fan 2 with the baffle 403, stopping the ventilation to prevent the external air from mixing with the leaked hydrogen to form a dangerous mixed gas. At the same time, it starts the alarm three 407 with the highest alarm level, emitting a strong alarm.

[0036] The air outlet component in the hydrogen generation mechanism 3 includes an electrolytic cell 301 fixedly installed inside the box body 1. An air outlet channel 302 is fixedly installed at the top end inside the electrolytic cell 301, and a valve 303 is fixedly connected to the outer wall of the air outlet channel 302;

[0037] Specifically, the gas outlet assembly in the hydrogen generation mechanism 3 includes an electrolytic cell 301 fixedly installed inside the box body 1. The electrolytic cell 301 uses the principle of electrolyzing water to decompose water into hydrogen and oxygen under the action of direct current. At the top inside the electrolytic cell 301, there is an air outlet channel 302 fixedly installed, which provides a path for the generated hydrogen to be discharged and prevents the mixing of impurities and moisture. The outer wall of the air outlet channel 302 is fixedly connected with a valve 303, which can accurately control the discharge amount and discharge speed of hydrogen. The operator controls the output of hydrogen by adjusting the valve 303 to meet different usage scenarios.

[0038] The auxiliary assembly includes a temperature sensor 304 fixedly installed on one side of the top outside the electrolytic cell 301, and a pressure sensor 305 fixedly installed on the other side of the top outside the electrolytic cell 301;

[0039] Specifically, the auxiliary assembly includes a temperature sensor 304 fixedly installed on one side of the top outside the electrolytic cell 301. The temperature sensor 304 can monitor the temperature change of the electrolytic cell 301 during operation in real time, and then transmit the collected temperature data to the control panel 7 in real time so that the operator can timely master the temperature situation. A pressure sensor 305 is fixedly installed on the other side of the top outside the electrolytic cell 301, and the pressure sensor 305 is mainly used to monitor the pressure inside the electrolytic cell 301.

[0040] The filtering and cooling assembly includes a filter screen 306 fixedly installed on the upper part of the electrolytic cell 301. An outer frame 307 is fixedly installed at the top of the electrolytic cell 301, and a plurality of cooling fans 308 are arranged around the inner side of the outer frame 307;

[0041] The filter screen 306 is arranged above the outlet end of the air outlet channel 302;

[0042] Specifically, the filtering and cooling assembly includes a filter screen 306 fixedly installed on the upper part of the electrolytic cell 301. The filter screen 306 can effectively filter the possible impurities in hydrogen. An outer frame 307 is fixedly installed at the top of the electrolytic cell 301, and the outer frame 307 provides an installation position and a support structure for the cooling fans 308 to ensure the stable operation of the cooling fans 308. A plurality of cooling fans 308 are arranged around the inner side of the outer frame 307, which can generate a strong air flow to cool the high-temperature hydrogen generated by the electrolytic cell 301. The cooled hydrogen has a temperature more in line with the requirements of subsequent use, and at the same time improves the stability and safety of hydrogen.

[0043] On the other side outside the box body 1, a control panel 7 is fixedly installed, and a plurality of control buttons 8 are arranged on one side of the control panel 7;

[0044] Specifically, on the other side outside the box body 1, a control panel 7 is fixedly installed. On one side of the control panel 7, there are multiple control buttons 8, which cover various functions such as starting, stopping, and parameter setting of the device. Operators can operate the device through the control buttons 8, such as starting the electrolytic cell 301, adjusting the opening degree of the valve 303, setting the alarm thresholds of temperature and pressure, etc. At the same time, the control panel 7 can also display the operating parameters of the device in real time, such as temperature, pressure, hydrogen concentration, etc., facilitating the operators to understand the working state of the device at any time.

[0045] The control panel 7 is electrically connected to the temperature sensor 304, the control panel 7 is electrically connected to the pressure sensor 305, and the control panel 7 is electrically connected to the hydrogen sensor 5;

[0046] Specifically, the control panel 7 is electrically connected to the temperature sensor 304. The temperature data collected by the temperature sensor 304 can be transmitted to the control panel 7 in real time for display. Operators can intuitively see the temperature change of the electrolytic cell 301. When the temperature exceeds the preset range, the control panel 7 can issue an alarm in time and can automatically adjust the working power of the electrolytic cell 301 according to the preset program to stabilize the temperature. The control panel 7 is electrically connected to the pressure sensor 305, and the pressure sensor 305 transmits the pressure data inside the electrolytic cell 301 to the control panel 7, and the control panel 7 analyzes and processes the pressure data. Once the pressure is abnormal, the control panel 7 will take corresponding measures to adjust the pressure by controlling the opening degree of the valve 303. The control panel 7 is electrically connected to the hydrogen sensor 5, and the hydrogen concentration data monitored by the hydrogen sensor 5 is fed back to the control panel 7 in real time. The control panel 7 controls the action of the alarm mechanism 4 according to the level of hydrogen concentration, realizing precise detection and alarm of hydrogen leakage.

[0047] Working principle: First, when the device is started, the electrolytic cell 301 generates hydrogen by electrolyzing water. During the electrolysis process, the temperature of the electrolytic cell 301 is monitored in real time through the temperature sensor 304, and the internal pressure is monitored by the pressure sensor 305. These data will be transmitted to the control panel 7 in real time. Once the temperature or pressure is abnormal, the control panel 7 will make corresponding adjustments according to the preset parameters, such as controlling the working power of the electrolytic cell 301 to stabilize the temperature and pressure, ensuring the safe and stable progress of the electrolysis process.

[0048] The generated hydrogen gas will first be processed by the filtration and cooling component. The filter screen 306 can effectively filter the impurities that may be contained in the hydrogen gas, ensuring the purity of the hydrogen gas. A plurality of cooling fans 308 arranged around the inner side of the outer frame 307 will cool the generated hydrogen gas, reducing the temperature of the hydrogen gas to make it more in line with the requirements of subsequent use. The hydrogen gas after filtration and cooling is discharged through the air outlet channel 302, and the valve 303 on the outer wall of the air outlet channel 302 can control the discharge amount and discharge speed of the hydrogen gas.

[0049] The hydrogen gas sensor 5 constantly detects the hydrogen gas concentration inside the box body 1. When the hydrogen gas generator is operating normally and there is no leakage, the hydrogen gas sensor 5 will not trigger the alarm device. Once hydrogen gas leakage occurs, the hydrogen gas sensor 5 will quickly detect the change in the hydrogen gas concentration and transmit the signal to the control panel 7.

[0050] After receiving the signal from the hydrogen gas sensor 5, the control panel 7 will control and adjust the alarm mechanism 4 according to the level of the hydrogen gas concentration. Adjust the shielding component in the alarm mechanism 4, and its baffle 403 is arranged at one end of the fan 2, and there is a shielding component at one end of each of the plurality of fans 2. When the hydrogen gas leakage amount is small, the control panel 7 controls the telescopic rod 404 to extend, pushing the baffle 403 to slide in the adjustment slot 402, so that part of the ventilation opening of the fan 2 is blocked, reducing the ventilation volume, avoiding excessive air entering the box body 1, and at the same time starting the alarm 405 with a lower alarm level to remind the operator to pay attention to the possible slight hydrogen gas leakage situation. As the hydrogen gas leakage amount increases and the hydrogen gas concentration continues to rise, the control panel 7 will further control the telescopic rod 404 to make the baffle 403 further block the ventilation opening of the fan 2, reducing the ventilation volume, and at the same time triggering the alarm 406 with a higher alarm level to attract the operator's high attention. If the hydrogen gas leakage situation is serious and the hydrogen gas concentration reaches the dangerous threshold, the control panel 7 will control the telescopic rod 404 to completely block the ventilation opening of the fan 2 with the baffle 403, stop the ventilation, prevent the external air from mixing with the leaked hydrogen gas to form a dangerous mixed gas, and at the same time start the alarm 407 with the highest alarm level to issue a strong alarm.

[0051] In addition, when the hydrogen gas generator is working normally, the fan 2 runs continuously to discharge the air inside the box body 1, keeping the air inside the box body 1 circulating and preventing hydrogen gas accumulation. When hydrogen gas leakage is detected, the ventilation volume of the fan 2 will be adjusted according to the control of the alarm mechanism 4. In the initial stage of leakage, the fan 2 operates with a small ventilation volume to avoid a large amount of air entering and quickly diluting the hydrogen gas concentration, affecting the judgment of the leakage situation; as the leakage situation changes, the fan 2 will stop running to prevent hydrogen gas from mixing with the external air and causing danger.

[0052] The operator can observe the situation inside the box body 1 through the observation window 6 at any time. Multiple control buttons 8 are set on the control panel 7, which facilitates the operator to control the equipment. The operator can also view the data collected by the temperature sensor 304, the pressure sensor 305 and the hydrogen sensor 5 to timely understand the operation status of the equipment.

[0053] In summary, a hydrogen generator with a hydrogen leakage self-check function realizes functions such as hydrogen generation, detection, filtration and cooling, leakage alarm and ventilation adjustment through the coordinated work of each component, ensuring the safety, stability and high efficiency of the hydrogen production process and meeting the hydrogen usage requirements in different scenarios.
