Description

Technical Field

[0001] The present invention relates to the field of hydrogen storage tank alarms, and particularly to a leakage prevention and alarm device for a hydrogen storage tank. Background Art

[0002] Existing hydrogen storage tank leakage alarms are generally integrated structures directly installed on hydrogen storage tanks. When a hydrogen storage tank fails or the alarm fails, it cannot be repaired or replaced separately. Without ensuring the use safety, enterprises can only discard the integrated hydrogen storage tank and then purchase a new safe and reliable hydrogen storage tank. The production cost of enterprises is high. If a separate hydrogen leakage alarm is used, when hydrogen leaks, the hydrogen diffuses into the air. General hydrogen leakage alarms can only passively come into contact with hydrogen in the air, and the detection result of the hydrogen concentration in the air after hydrogen leakage is inaccurate and the detection result is delayed, resulting in untimely handling of the hydrogen leakage problem and the occurrence of hydrogen explosion. Summary of the Invention

[0015] 2. The buzzer emits sound. After the sound passes through the top cover, the top cover functions as a loudspeaker, making the sound energy emitted by the buzzer more concentrated and the sound propagation distance farther. The staff can better locate the position of the hydrogen storage container body where leakage occurs through the sound and the flashing LED indicator lights. According to the different colors of the flashing of different LED indicator lights, the danger level is judged, and then corresponding measures are taken to urgently handle the hydrogen storage container body, greatly reducing the processing reaction time for hydrogen leakage. The structure is simple, the effect is excellent, the practicability is strong, and the production safety of the enterprise is greatly guaranteed.

[0016] 3. By reversing the fan blades and the fan, the air is blown downward, and the air flows towards the hydrogen storage container body, thereby locally diluting the hydrogen leaked from the hydrogen storage container body, specifically diluting the hydrogen leaked from the hydrogen storage container body, effectively avoiding the situation of hydrogen explosion when the staff is dealing with the leakage problem of the hydrogen storage container body, and greatly ensuring the physical and mental health of the staff.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Although the present invention may be described in relation to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent a limitation on the scope of the present invention as defined by the appended claims. Any numerical labels such as first or second are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0023] The first embodiment

[0024] An anti-leakage alarm device for a hydrogen storage container, according to Figures 1-4 As shown, it includes a base 1 and a vertical beam 2; the vertical beam 2 is fixedly connected to the base 1;

[0025] It further includes a DD motor 3, a cantilever beam 4, a hollow ring 5, an LED indicator light 6, a top cover 7, a suspension 8, a gas sensor 9, a buzzer 10, and a gas pipe 11; the DD motor 3 is installed on the vertical beam 2; the rotating part of the DD motor 3 is fixedly connected to the cantilever beam 4; the cantilever beam 4 is bolted to the hollow ring 5; several LED indicator lights 6 are installed on the hollow ring 5; the top cover 7 is bolted to the upper part of the hollow ring 5; the top cover 7 is fixedly connected to the suspension 8, and a data wireless transmission module is provided inside the suspension 8; several gas sensors 9 are installed on the side of the suspension 8; a buzzer 10 is installed on the upper part of the suspension 8; the gas sensor 9 is located above the hydrogen storage container body 001; the upper part of the top cover 7 is communicated with the gas pipe 11; the vertical beam 2 is a hollow pipe, and several air holes Ⅰ2001 are opened at the lower part; the gas pipe 11 is communicated with the vertical beam 2.

[0026] A distance sensor is provided inside the vertical beam 2.

[0027] All the LED indicator lights 6 are evenly distributed on the outer ring surface of the hollow ring 5 and are used to synchronously flash and give an alarm around, so that the surrounding staff can receive the light alarm fastest at each position, and different colors are set for the LED indicator lights 6. By the flashing of the LED indicator lights 6 of different colors, different alarm levels are represented, and the information expression is richer.

[0028] The top cover 7 is in a horn shape, and the large mouth faces the side of the hydrogen storage container body 001; the suspension 8 is located in the middle of the small mouth of the top cover 7; there is a gap between the suspension 8 and the top cover 7, and the gas sensor 9 is located in the gap between the outer ring surface of the suspension 8 and the top cover 7, so that when the air flow passes through the gap between the outer ring surface of the suspension 8 and the top cover 7, the gas sensor 9 is in full contact with the air flow and detects the hydrogen content therein.

[0029] An anti-static coating is applied on the suspension 8 to reduce dust adhesion to the suspension 8.

[0030] It further includes a motor 101, a gear I 102, a swivel ring 103, an external gear ring 104 and a fan blade 105; a motor 101 is installed on the upper part of the hollow ring 5; the output shaft of the motor 101 is fixedly connected to the gear I 102; the hollow ring 5 is rotatably connected to the swivel ring 103; the outer ring surface of the swivel ring 103 is fixedly connected to the external gear ring 104; the external gear ring 104 meshes with the gear I 102; several fan blades 105 are welded to the inner ring surface of the swivel ring 103.

[0031] The working steps of the above-mentioned embodiment are as follows:

[0032] Before use, first, an external crane hooks the two lifting lugs on the hydrogen storage device body 001, as Figure 1 and Figure 2 shown, move the hydrogen storage device body 001 to a position close to the base 1. When the distance sensor on the vertical beam 2 detects the approach of the hydrogen storage device body 001, at this time, control the start of the DD motor 3. The DD motor 3 drives the suspension beam 4 and the corresponding parts thereon to rotate, so that the hollow ring 5 and the corresponding parts thereon move away from directly above the base 1. Then move the hydrogen storage device body 001 to directly above the base 1 and fix the hydrogen storage device body 001. Then control the external crane to release the hydrogen storage device body 001, and then control the start of the DD motor 3 to make the hollow ring 5 and the corresponding parts thereon reset. Since the hydrogen leakage alarm is a highly sensitive device, by actively avoiding, the collision of the main components of the alarm is reduced, so as to prevent the alarm from being damaged, resulting in false alarms and missed alarms, and ensuring the safety of the working environment. At this time, the gas sensor 9 is located above the hydrogen storage device body 001, and the hydrogen storage material in the hydrogen storage device body 001 starts to release hydrogen for production and living use. Since the density of hydrogen is much smaller than the density of air, and the hydrogen storage device body 001 is generally an integrally formed high-pressure container, if the hydrogen storage device body 001 leaks, the leakage position is generally at the pipe interface, and the leaked hydrogen quickly floats up and is then detected by the gas sensor 9. Then the gas sensor 9 imports the hydrogen content data into the computer through the preset data wireless transmission module in the suspension 8. Then the computer monitors and analyzes the hydrogen content in real time. If the hydrogen concentration exceeds the standard, the computer feeds back and controls the LED indicators 6 of different colors to flash, indicating different levels of danger alarms. At the same time, control the start of the buzzer 10 to give a warning to the staff in the workshop, so that the staff can quickly reach the position of the leaking hydrogen storage device body 001 to handle the leakage problem of the hydrogen storage device body 001, and the separate maintenance and replacement of the hydrogen storage device body 001 and the alarm are more convenient and the cost is low.

[0033] On the basis of the above operations, we also need to consider that when the hydrogen storage container body 001 leaks, an alarm needs to be given. The components related to the alarm are not too large, so they cannot completely cover the upper part of the hydrogen storage container body 001. As a result, the leaked hydrogen escapes into the air without passing through the position of the gas sensor 9, leading to untimely alarm and the problem of hydrogen leakage not being handled in time, presenting a risk of hydrogen explosion. Therefore, a rotating ring 103 and its related components are added here. The starting motor 101 is controlled. The output shaft of the motor 101 drives the gear Ⅰ 102 to drive the external gear ring 104 to rotate. The external gear ring 104 drives the rotating ring 103 to drive the fan blade 105 to rotate. When viewed from top to bottom, the rotating direction of the rotating ring 103 is clockwise. The fan blade 105 blows the air below upwards. With the cooperation of the bell-shaped top cover 7, the blown air is more concentrated above the top cover 7, thereby enabling the gas sensor 9 to be in more sufficient contact with the air. The gas sensor 9 more fully detects the hydrogen content in the air and obtains a hydrogen content in the air closer to the actual value. By actively concentrating the air to the position of the gas sensor 9 to detect the hydrogen content in the air, it is avoided that the hydrogen content exceeds the standard and is not detected in time, resulting in untimely treatment of hydrogen leakage and the occurrence of hydrogen explosion. Moreover, the air blown into the top cover 7, after being detected by the gas sensor 9, enters the hollow vertical beam 2 through the air duct 11 and finally is discharged into the air through the air hole Ⅰ 2001 serving as the air outlet below the vertical beam 2. The discharged hydrogen is far from the position of the gas sensor 9, reducing the situation of false alarms. Also, because the density of hydrogen is smaller than that of air, the discharged hydrogen quickly floats upwards and, during the floating process, is fully mixed with the air to further dilute the hydrogen concentration and reduce the threat caused by hydrogen explosion.

[0034] And if the gas sensor 9 detects that the hydrogen content in the air exceeds the standard, the buzzer 10 is automatically activated to remind the staff in the workshop that there is a hydrogen leakage situation. The buzzer 10 emits a sound. After the sound passes through the top cover 7, the bell-shaped top cover 7 functions as an amplifier, making the sound energy emitted by the buzzer 10 more concentrated and the sound propagation distance farther. The staff can better locate the position of the leaking hydrogen storage container body 001 through the sound and the flashing LED indicator light 6 and perform emergency treatment on the hydrogen storage container body 001, greatly reducing the treatment reaction time for hydrogen leakage. The structure is simple, the effect is excellent, the practicability is strong, and it greatly guarantees the production safety of the enterprise.

[0035] The second embodiment

[0036] On the basis of the first embodiment, according to Figures 1-4As shown in the figure, it further includes a rotating shaft 201, a gear II 202, a fan 203 and a sealing piece 204; there is an annular cavity between the rotating ring 103 and the hollow ring 5, and several rotating shafts 201 are rotatably connected in the annular cavity; a gear II 202 is fixedly connected to each rotating shaft 201; the external gear ring 104 meshes with all the gears II 202; one of the rotating shafts 201 is fixedly connected to the gear I 102; a fan 203 is fixedly connected to the lower part of each rotating shaft 201; several air holes I 5001 are opened in the lower part of the hollow ring 5; each air hole I 5001 corresponds to a fan 203; several air holes II 5002 are opened in the upper part of the hollow ring 5; several sealing pieces 204 are fixedly connected to the upper part of the hollow ring 5; the sealing piece 204 is made of rubber; only one end of the sealing piece 204 is fixed; several air holes II 10301 are opened in the rotating ring 103.

[0037] Dust-proof nets are provided at both the air holes I 5001 and the air holes II 5002.

[0038] It further includes a support frame 12 and a placement shell 13; the base 1 is fixedly connected to the support frame 12; the support frame 12 is fixedly connected to the vertical beam 2; the support frame 12 is welded with the placement shell 13; the placement shell 13 is detachably connected to the hydrogen storage device body 001.

[0039] A cavity is opened inside the placement shell 13, and a heat-conducting liquid is filled in the cavity. By controlling the temperature of the heat-conducting liquid, the temperature of the placement shell 13 is further controlled.

[0040] The working steps of the above embodiment are as follows:

[0041] On the basis of the above embodiment, through the rotation of the fan blade 105, the air is concentrated towards the gas sensor 9, and the gas sensor 9 is in more sufficient contact with the air, and the detection of the hydrogen content in the air is more accurate. Therefore, a fan 203 is added. When the external gear ring 104 rotates, it drives the corresponding gear II 202 to rotate, and drives the corresponding fan 203 to rotate through the rotating shaft 201, so that the air enters the annular cavity between the hollow ring 5 and the rotating ring 103 through the air hole I 5001. Since at this time each sealing piece 204 blocks the corresponding air hole II 5002, the air pressure in the annular cavity increases, so that the air entering the annular cavity enters the area where the fan blade 105 rotates through the air hole II 10301, and then with the rotation of the fan blade 105, the air is blown upwards, thereby increasing the air flow rate through the gas sensor 9 and making the detection result of the hydrogen content in the air more accurate.

[0042] It should also be taken into account that when the staff arrives near the hydrogen storage tank body 001 where hydrogen leakage occurs after receiving the warning, the staff generally closes the relevant pipeline connection switches on the hydrogen storage tank body 001. At this time, the heat-conducting liquid in the placement shell 13 can also be pumped out through the conduit on the placement shell 13 to connect to the external heat-conducting liquid circulation device, and then the cooled heat-conducting liquid is pumped into the placement shell 13, thereby controlling the temperature drop of the placement shell 13. Through the direct contact between the placement shell 13 and the hydrogen storage tank body 001, the temperature of the hydrogen storage tank body 001 is reduced, thereby reducing the release of hydrogen in the hydrogen storage tank body 001 and further reducing hydrogen leakage. The heat-conducting liquid can also be heated by the external heat-conducting liquid circulation device to increase the temperature of the hydrogen storage tank body 001, so that the hydrogen storage material in the hydrogen storage tank body 001 releases hydrogen to meet the needs of production and life. However, the leaked hydrogen generally needs to be diluted by controlling the opening of the ventilation equipment in the workshop to force the air flow in the workshop, and then the air in the workshop is discharged to the outside, thereby diluting the hydrogen concentration in the workshop air and avoiding the occurrence of hydrogen explosion. However, it takes a long time to replace the air in the workshop through the ventilation equipment in the workshop, and the hydrogen leakage content near the hydrogen storage tank body 001 is higher. At this time, the LED indicator light 6 and the buzzer 10 continue to work, controlling the output shaft of the starting motor 101 to reverse. Looking down from above, the rotating ring 103 rotates counterclockwise, and synchronously drives the fan blade 105 to rotate. When the fan blade 105 blows the air above downward, a negative pressure is formed inside the top cover 7, and the outside air enters the hollow vertical beam 2 through the air hole Ⅰ2001 acting as an air inlet, and then the outside air enters the top cover 7 through the air duct 11. The outside air needs to pass through a long and tortuous path to reach the position of the fan blade 105, and then the air is blown downward with the rotation of the fan blade 105. The blown air has a limited effect on diluting hydrogen. Therefore, through the cooperation of the external gear ring 104 and the gear Ⅱ202, the fan 203 is synchronously driven to reverse. When the fan 203 rotates, the air in the annular cavity is blown downward through the air hole Ⅰ5001. The air pressure in the annular cavity decreases. At this time, the rubber sealing piece 204 deforms, and the movable end of the sealing piece 204 is separated from the hollow ring 5, and the air hole Ⅱ5002 is opened. The outside air enters the annular cavity, and then with the rotation of the fan 203, the air flows downward. At this time, the air blown out from the annular cavity and the air blown out by the rotation of the fan blade 105 both flow towards the hydrogen storage tank body 001. Cooperating with the fan blade 105 to blow the air downward, the air flow blown towards the hydrogen storage tank body 001 is increased, thereby quickly locally diluting the hydrogen leaked from the hydrogen storage tank body 001, specifically diluting the hydrogen leaked at the hydrogen storage tank body 001, effectively avoiding the situation of too high local hydrogen concentration and hydrogen explosion when the staff is dealing with the leakage problem of the hydrogen storage tank body 001, and greatly ensuring the physical and mental health of the staff.

[0043] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
