[0027] In the following description, specific details are set forth in connection with the specific system structures, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. However, it should be apparent to those skilled in the art that the present application can be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary details.

[0028] Please refer to Figures 1 to 4 The device for monitoring hydrogen in oxygen in the alkaline electrolytic water system of the first embodiment of the present application comprises a hydrophobic protection assembly 1 mounted in the alkaline electrolytic water hydrogen production system in advance, and a monitoring module 2 mounted in the hydrophobic protection assembly 1. The inside of the hydrophobic protection assembly 1 is connected with the alkaline electrolytic water hydrogen production system. The hydrophobic protection assembly 1 comprises a mounting seat 11 fixed or detachably vertically mounted on the conveying path of the alkaline electrolytic water hydrogen production system, a cover 12, a condensing part 13 and a hydrophobic assembly 14. The cover 12 is mounted on the mounting seat 11. A gas inlet 3 connected with the alkaline electrolytic water hydrogen production system is formed in the lower part of the mounting seat 11. A curved channel 131 connected with the monitoring module 2 and the alkaline electrolytic water hydrogen production system is arranged in the mounting seat 11. The monitoring module 2 is arranged at the top of the curved channel 131. The hydrophobic assembly 14 is arranged between the cover 12 and the mounting seat 11. A hydrophobic channel 141 is further arranged between the cover 12 and the mounting seat 11. The condensing part 13 is arranged above the cover 12. The water droplets condensed from the gas are guided into the hydrophobic channel 141 through the hydrophobic assembly 14. The curved channel 131 and the upper part of the hydrophobic channel 141 are connected with each other.

[0029] The monitoring module 2 in the hydrophobic protection assembly 1 is closer to the electrolytic tank, and the monitoring module 2 can timely monitor the content of hydrogen in the gas when the gas is generated, thereby improving the monitoring accuracy, and the monitoring value can be timely transmitted to the background operating system, so that the staff can timely feedback and improve the safety.

[0030] The gas generated in the alkaline electrolytic water hydrogen production system enters the mounting seat 11 vertically installed on the conveying path of the alkaline electrolytic water hydrogen production system through the gas inlet 3, enters the curved channel 131, and delays the speed of the gas, so that the gas is mixed with each other, and the content of hydrogen in the gas is more uniform. The mixed gas slowly advances upward in the curved channel 131, and when the uniformly mixed gas reaches the top of the curved channel 131, it contacts the monitoring head of the monitoring module 2, and the content of hydrogen in the uniformly mixed gas is monitored by the monitoring module 2, thereby improving the accuracy of the monitoring value and further improving the safety.

[0031] When the gas enters the curved channel 131, the temperature of the gas can be reduced by heat conduction, so that the overall temperature of the gas is reduced, and after the gas passing through the curved channel 131 contacts the monitoring module 2, the monitoring module 2 will not be seriously scalded, thereby protecting the monitoring module 2 to a certain extent, further prolonging the service life of the monitoring module 2, reducing the maintenance cost, reducing the content of condensate water on the surface of the monitoring module 2 in the high-humidity environment, further improving the monitoring accuracy, and enabling the monitoring module 2 to maintain good signal transmission and monitoring function for a long time, further improving the stability of the monitoring module 2 during operation.

[0032] The condensing piece 13 is arranged above the cover 12, and the water droplets condensed by the condensing piece 13 are guided into the hydrophobic channel 141 by the hydrophobic assembly 14. The gas passing through the monitoring module 2 is condensed into water droplets by the condensing piece 13, which can reduce the overall content of the gas in the mounting seat 11 when the gas is continuously conveyed into the mounting seat 11, thereby reducing the temperature in the mounting seat 11 and further protecting the monitoring module 2. After the gas passing through the monitoring module 2 is condensed into water droplets by the condensing piece 13, the gas can be prevented from falling back around the monitoring module 2 after being monitored by the monitoring module 2, which affects the monitoring value of the monitoring module 2, further improves the accuracy of the monitoring module 2, prolongs the service life of the monitoring module 2, and reduces the maintenance cost. The water droplets condensed by the condensing piece 13 can be gathered together by the hydrophobic assembly 14, which is convenient for cleaning, can further reduce the temperature in the mounting seat 11, protects the monitoring module 2, reduces the water droplets covering the monitoring module 2, and improves the accuracy of the monitoring value.

[0033] Since the cover 12 is installed on the mounting seat 11 in reverse, when the monitoring module 2 is damaged, the staff can disassemble the cover 12 from the mounting seat 11, and then replace the monitoring module 2, thereby facilitating operation, improving the efficiency of maintenance, and reducing the labor intensity of the staff.

[0034] Please refer to Figures 1 to 4 In some embodiments, a plurality of vertical staggered shielding pieces 132 are installed in the mounting seat 11, and the shielding pieces 132 form curved channels 131 therebetween.

[0035] The present application installs a plurality of vertical staggered shielding pieces 132 in the mounting seat 11, and the shielding pieces 132 form curved channels 131 therebetween. The shielding pieces 132 can further slow down the movement of the generated gas, further mix the gas, improve the uniformity of hydrogen in the gas, and thereby improve the accuracy of the monitoring value of the monitoring module 2. The shielding pieces 132 can also provide a certain support force for the mounting seat 11, improving the stability of the mounting seat 11 during operation. The plurality of shielding pieces 132 installed in a vertical staggered manner can separate the gas, making the curved channels 131 have more structures, and thereby making the hydrophobic protection assembly 1 more diverse and suitable for more use environments.

[0036] Please refer to Figures 1 to 4 In some embodiments, the condensing piece 13 is in the shape of a funnel, a hemisphere, or a polygon with a closed top end.

[0037] The present application makes the condensing piece 13 in the shape of a funnel, a hemisphere, or a polygon with a closed top end. The outer side of the condensing piece 13 is in contact with the outside air, and through heat transfer, the internal surface temperature of the condensing piece 13 is relatively low. When the gas comes into contact with the internal surface of the condensing piece 13, the gas will be condensed into water droplets by the low temperature, and will be attached to the inner surface of the condensing piece 13, further cooling the inside of the mounting seat 11 and protecting the monitoring module 2.

[0038] When the condensing piece 13 is in the shape of a funnel with a closed top end, the water droplets condensed on the inner surface of the condensing piece 13 will flow down the inclined inner surface of the condensing piece 13 and enter the drainage channel 141 for collection and centralized processing, thereby reducing the labor intensity and reducing the impact of water droplets falling on the monitoring module 2 on the monitoring value of the monitoring module 2, further improving the accuracy of the monitoring module 2.

[0039] When the condensing piece 13 is in the shape of a hemisphere with a closed top end, the top arc of the hemispherical condensing piece 13 is located at the top end. The hemispherical condensing piece 13 increases the contact area with the outside, can expand the efficiency of heat transfer, thereby improving the efficiency of condensing water droplets, further avoiding the impact of gas backfall on the value of the monitoring module 2, and further improving the accuracy of the monitoring module 2.

[0040] When the condensing member 13 is a polygon with a closed top end, different shapes of the condensing member 13 can be set according to different installation environments, thereby being applicable to more use environments and improving the condensation efficiency of the gas.

[0042] The first liquid blocking member 142 can avoid the water droplets condensed by the condensing member 13 from falling on the monitoring module 2 or in the curved channel 131, avoid the water droplets from covering the monitoring module 2, affect the monitoring accuracy of the monitoring module 2, further improve the accuracy of the monitoring module 2, and further protect the monitoring module 2. The first liquid blocking member 142 can also reduce the water droplets falling into the curved channel 131, avoid the running gas from being disturbed, further improve the accuracy of the monitoring value, and protect the shielding member 132 to a certain extent, thereby prolonging the service life of the shielding member 132.

[0043] The second liquid blocking member 143 arranged at the upper part of the first liquid blocking member 142 can further protect the monitoring module 2, prevent the water droplets from falling on the monitoring module 2, affect the monitoring value of the monitoring module 2, and prolong the service life of the monitoring module 2. After the gas passes through the second liquid blocking member 143, the second liquid blocking member 143 can avoid the backfall of the gas, further improve the monitoring accuracy of the monitoring module 2. The gap arranged between the first liquid blocking member 142 and the second liquid blocking member 143 can make the gas flow smoothly upward after passing through the monitoring module 2, thereby making the entire monitoring process more smooth and improving the monitoring efficiency.

[0044] Please refer to Figures 1 to 4 In some embodiments, the second liquid blocking member 143 is in the shape of a semicircle with a round top, a cone, or a flat plate.

[0045] The second liquid blocking member 143 is in the shape of a semicircle with a round top, a cone, or a flat plate.

[0046] The second liquid blocking member 143 in the shape of a semicircle with a round top has stronger impact resistance, can evenly disperse the falling gravity of the water droplets, is not easy to deform, and has a longer service life.

[0047] The second liquid blocking part 143 in the shape of a cone can more smoothly guide the water droplets falling down to the first liquid blocking part 142, and the water droplets are gathered together by the first liquid blocking part 142 to enter the hydrophobic channel 141, so that the water droplets are prevented from being scattered, the hydrophobic efficiency is improved, and the water droplets are conveniently collected for processing later.

[0048] The bottom end of the second liquid blocking part 143 in the shape of a flat plate is a plane, so that the gas is not backflowed, the gas can be smoothly guided to the gap between the first liquid blocking part 142 and the second liquid blocking part 143 to reach the condensing part 13, the condensing efficiency is improved, and the accuracy of the monitoring value of the monitoring module 2 is further improved.

[0049] Please refer to Figures 1 to 4 In some embodiments, a plurality of drainage parts 144 parallel to each other are arranged on the first liquid blocking part 142, and the drainage parts 144 are provided with drainage surfaces inclined to both sides.

[0050] The plurality of drainage parts 144 parallel to each other are arranged on the first liquid blocking part 142, and the drainage parts 144 are provided with drainage surfaces inclined to both sides, so that the water droplets on the first liquid blocking part 142 are gathered together by the drainage parts 144 to form water flow flowing down from the first liquid blocking part 142, the water droplet cleaning efficiency is improved, the bearing pressure of the first liquid blocking part 142 is reduced, the deformation of the first liquid blocking part 142 is prevented, the water droplets flowing down quickly can also reduce the corrosion of the first liquid blocking part 142, and the service life of the first liquid blocking part 142 is prolonged. The drainage parts 144 are provided with drainage surfaces inclined to both sides, so that the water droplets can be more quickly gathered into water flow, the corrosion of the first liquid blocking part 142 is further reduced, and the service life thereof is prolonged.

[0051] Please refer to Figures 1 to 4 In some embodiments, the mounting seat 11 is provided with a water outlet 4 in communication with the lower part of the hydrophobic channel 141.

[0052] The mounting seat 11 is provided with the water outlet 4 in communication with the lower part of the hydrophobic channel 141, so that the water flow gathered in the hydrophobic channel 141 can be continuously discharged by the water outlet 4, the pressure of the entire device is reduced, a negative pressure is continuously generated, the gas continuously passes through the monitoring module 2, the monitoring efficiency is improved, a pipeline can be installed at the water outlet 4, and the water flow can be prevented from polluting the surrounding environment.

[0053] Please refer to Figures 1 to 4 In some embodiments, the hydrophobic assembly 14 further comprises a flow converging part 145 installed in the hydrophobic channel 141, and the flow converging part 145 is inclined to the water outlet 4.

[0054] The application can further converge the water flow and water droplets in the hydrophobic channel 141 by installing the flow converging piece 145 in the hydrophobic channel 141, which is inclined to the water outlet 4. The flow converging piece 145 can increase the efficiency of water flow out of the hydrophobic channel 141, and can also avoid water droplets from hanging in the hydrophobic channel 141, further improving the efficiency of water flow out of the hydrophobic channel 141, and reducing the corrosion of water flow to the lower part of the hydrophobic channel 141, facilitating replacement and prolonging the service life.

[0055] Referring to Figures 1 to 4 In some embodiments, the curved channel 131 is S-shaped, herringbone-shaped or spiral-shaped.

[0056] The S-shaped curved channel 131 can slow down the speed of the gas advancing, so that the gas can slowly and uniformly reach the monitoring module 2 around for monitoring, thereby improving the monitoring accuracy.

[0057] Similarly, the spiral-shaped curved channel 131 can further slow down the speed of the gas advancing, thereby improving the monitoring accuracy.

[0058] The herringbone-shaped curved channel 131 can first split the gas, and then make the two streams of gas converge together to form a mixed flow through the top structure, thereby further mixing the gas and making the hydrogen more uniform in the gas, and improving the monitoring accuracy.

[0059] Referring to Figures 1 to 4 In some embodiments, the monitoring module 2, the curved channel 131 and the hydrophobic channel 141 are coated with a hydrophobic layer.
