DETAILED DESCRIPTION

[0017] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0018] Example 1 An intelligent hydrogenation gun, such as Figure 1-Figure 5 As shown, it includes a connecting plate 1, a cylinder 2 and a hydrogenation gun body 3; the connecting plate 1 is bolted with a cylinder 2, and the connecting plate 1 is set to an alloy material; the hydrogenation gun body 3 is plugged into the cylinder 2; a hydrogen concentration detector is installed on the output port of the hydrogenation gun body 3; it also includes a cylinder 4, an electric push rod 5, a connecting block 6, a soft rubber cone 7, a plug 8, a rubber pad 9, a modified activated carbon cylinder 10 and a fixing component; the connecting plate 1 is bolted with a cylinder 4, and the cylinder 4 is in contact with the cylinder 2; the cylinder 4 is installed with an electric push rod 5; the telescopic end of the electric push rod 5 is fixed It is connected with a connecting block 6; a soft rubber cone 7 is fixedly connected between the cylinder 2 4 and the connecting block 6; a plug 8 is connected to the connecting block 6; a cavity 91 is formed between the hydrogenation gun body 3, the cylinder 2 4, the connecting block 6 and the soft rubber cone 7; a cavity 92 is formed between the cylinder 2 4, the connecting block 6 and the soft rubber cone 7; a rubber pad 9 is fixedly connected to the plug 8; a modified activated carbon cylinder 10 is detachably connected to the cylinder 2 4, and the modified activated carbon cylinder 10 is in contact with the cylinder 2; a fixing component is connected to the connecting plate 1, and the fixing component is used to fix the hydrogenation gun body 3.

[0019] A sealing ring is provided at the position of the hydrogenation gun body 3 corresponding to the cylinder 2 to seal the gap between the cylinder 2 and the hydrogenation gun body 3.

[0020] The fixing assembly includes a U-shaped block 201, an L-shaped block 202 and a spring 203; the U-shaped block 201 is welded on the connecting plate 1, and the U-shaped block 201 is set to an alloy material; the L-shaped block 202 is slidably connected to the U-shaped block 201, and the hydrogenation gun body 3 is fixed by matching the U-shaped block 201 and the L-shaped block 202; the spring 203 is fixed between the U-shaped block 201 and the L-shaped block 202.

[0021] During hydrogenation, the staff pushes the L-shaped block 202 to move downward, and the L-shaped block 202 stretches the spring 203 until the upper end of the L-shaped block 202 moves to the inside of the U-shaped block 201, so that the L-shaped block 202 stops locking the hydrogenation gun body 3, and then the staff pulls the hydrogenation gun body 3 forward and stops pushing the L-shaped block 202. The spring 203 rebounds and drives the L-shaped block 202 to move back to its original position. The staff performs hydrogenation operation on the car through the hydrogenation gun body 3. After the hydrogenation is completed, the staff pushes the L-shaped block 202 downward again, so that the upper end of the L-shaped block 202 moves to the inside of the U-shaped block 201, and then the staff inserts the hydrogenation gun body 3 back to its original position and stops applying force to the L-shaped block 202. The spring 203 rebounds and drives the L-shaped block 202 to move back to its original position. At this time, the U-shaped block 201 limits the left and right directions of the hydrogenation gun body 3, and the cylinder 2 and the L-shaped block 202 cooperate to limit the front and rear directions of the hydrogenation gun body 3, thereby locking the hydrogenation gun body 3. When the hydrogenation gun body 3 is inserted into the cylinder 2 and hydrogenation is stopped, the hydrogen concentration in the output port of the hydrogenation gun body 3 is intelligently monitored through the hydrogen concentration detector on the output port of the hydrogenation gun body 3. If the hydrogen concentration rises, it can be determined that the hydrogenation gun body 3 is leaking. At this time, the hydrogen concentration detector transmits the detection result data to the control center to remind the staff to go to the hydrogenation station for maintenance operations, and the leaked hydrogen flows into the hydrogenation gun body 3. To the cavity 91, and contact with the modified activated carbon cartridge 10, the leaked hydrogen is adsorbed and collected by the modified activated carbon cartridge 10, at the same time, the electric push rod 5 is started, the electric push rod 5 drives the connecting block 6 to move forward, the connecting block 6 drives the plug 8 to move forward, so that the plug 8 is inserted into the end position of the output port of the hydrogenation gun body 3, the plug 8 presses the rubber pad 9 on the end of the hydrogenation gun body 3, and the gap between the hydrogenation gun body 3 and the plug 8 is sealed by the rubber pad 9, that is, during the maintenance period, the end of the hydrogenation gun body 3 is blocked by the plug 8 and the rubber pad 9 to prevent continuous leakage of hydrogen, and when the electric push rod 5 drives the connecting block 6 to move forward, the connecting block 6 presses the soft rubber The rubber cone cylinder 7 is stretched, that is, in the blocking process, the electric push rod 5 as the power drive component is isolated outside the cavity 91 through the cooperation of the connecting block 6 and the soft rubber cone cylinder 7, which is beneficial to improve the safety. When in use, the hydrogen leaked from the hydrogenation gun body 3 is adsorbed and collected through the cooperation of the cylinder 2 4 and the modified activated carbon cylinder 10, and the end of the hydrogenation gun body 3 is blocked by the plug 8 and the rubber pad 9 to avoid continuous leakage of hydrogen, which greatly improves the safety performance. At the same time, the electric push rod 5 as the power drive component is isolated outside the cavity 91 through the cooperation of the connecting block 6 and the soft rubber cone cylinder 7 to avoid hydrogen explosion caused by leakage of the electric push rod 5, which further improves the safety performance.

[0022] Example 2 On the basis of Example 1, Figure 5 and Figure 6 As shown, it also includes a plugging component; the plugging component is connected to the connecting block 6; the plugging component includes a magnet 204, a friction ring 1 205 and a friction ring 2 206; the connecting block 6 is in contact with the plug 8; the magnet 204 is fixedly connected to the connecting block 6, and the magnet 204 sucks the plug 8 tightly through magnetic force; the friction ring 1 205 is fixedly connected to the plug 8, and the friction ring 1 205 is set to be made of rubber material; the friction ring 2 206 is fixedly connected to the hydrogenation gun body 3.

[0023] The edge of the magnet 204 is chamfered to make it easier for the magnet 204 to be inserted into the plug 8 .

[0024] When the staff performs maintenance on the leaking hydrogenation gun body 3, the hydrogenation gun body 3 should be pulled out from the cylinder 1 2. At this time, the hydrogenation gun body 3 will be away from the plug 8, resulting in the hydrogenation gun body 3 continuing to leak after the hydrogenation gun body 3 is pulled out, which poses a certain safety hazard. Therefore, when the electric push rod 5 inserts the plug 8 into the end of the hydrogenation gun body 3, the plug 8 drives the friction ring 1 205 to move to the outside of the friction ring 2 206, so that the friction ring 1 205 and the friction ring 2 206 are in close contact. At the same time, the plug 8 drives the rubber pad 9 to fit closely to the output port of the hydrogenation gun body 3 to block it. When the staff pulls out the hydrogenation gun body 3 for maintenance, the hydrogenation gun body 3 drives the friction ring 2 206 to move forward, and the friction ring 2 206 contacts the friction ring 1 205 applies a forward friction force, and the friction force is much greater than the attraction between the magnet 204 and the plug 8, so that the friction ring 206 drives the friction ring 1 205 to move forward through the friction force, and the friction ring 1 205 drives the plug 8 to move forward, so that the plug 8 is away from the connecting block 1 6 and the magnet 204, that is, the worker manually takes out the hydrogenation gun body 3 and the plug 8 together. During the removal and maintenance of the hydrogenation gun body 3, the plug 8 can still block the end of the hydrogenation gun body 3 to prevent hydrogen leakage. When in use, through the cooperation of the magnet 204, the friction ring 1 205 and the friction ring 2 206, the worker takes out the hydrogenation gun body 3 and the maintenance, and the plug 8 can still block the end of the hydrogenation gun body 3 to prevent hydrogen leakage, thereby further improving the safety performance.

[0025] Example 3 On the basis of Example 2, Figure 5-Figure 7 As shown, it also includes a pipe 207; the pipe 207 is fixedly connected to the cylinder 4, and the pipe 207 is connected to the cavity 92, and air is transported to the cavity 92 through the pipe 207.

[0026] It also includes a guide block 208; a plurality of inclined guide blocks 208 are fixedly connected to the modified activated carbon cartridge 10, and the gas flowing in the cavity 91 is guided to the inner wall of the modified activated carbon cartridge 10 through the guide blocks 208.

[0027] The guide blocks 208 are distributed in a staggered manner.

[0028] It also includes a second connecting block 209; the second connecting block 209 is welded between the U-shaped block 201 and the connecting plate 1 to enhance the structural stability.

[0029] The surface of the connecting plate 1 is coated with a paint layer for rust prevention.

[0030] First, the external air pump is manually connected to the pipeline 207. When hydrogen leakage occurs in the hydrogenation gun body 3, the end of the hydrogenation gun body 3 is blocked by the plug 8, and then the hydrogen leaked into the cavity 91 is absorbed by the modified activated carbon cartridge 10. At this time, the gas in the cavity 91 is in a non-circulating state, resulting in low absorption efficiency of hydrogen by the modified activated carbon cartridge 10. Therefore, air is transported to the pipeline 207 through the external air pump, and the pipeline 207 transports the air to the cavity 92, forcing the soft rubber cone 7 to expand and deform. The expanded soft rubber cone 7 pushes the gas in the cavity 91 to move, and then the external air pump is connected to the pipeline 207. 7 inhales, so that the gas in cavity 92 is discharged through pipe 207, thereby causing the soft rubber cone 7 to shrink and deform, and the external air pump reciprocates to draw air from pipe 207, so that the soft rubber cone 7 reciprocates to expand and shrink, thereby causing the soft rubber cone 7 to intermittently disturb the movement of gas in cavity 1 91, so that the hydrogen in cavity 1 91 is in full contact with the modified activated carbon cylinder 10, which is beneficial to improving the absorption efficiency. When in use, the soft rubber cone 7 used to isolate and protect the electric push rod 5 is also used to intermittently disturb the movement of gas in cavity 1 91, so that the hydrogen in cavity 1 91 is in full contact with the modified activated carbon cylinder 10, which is beneficial to the hydrogen adsorption efficiency.

[0031] When the soft rubber cone 7 expands and compresses the volume of the cavity 91, the guide block 208 is pre-designed to block the gap between the hydrogenation gun body 3 and the inner wall of the modified activated carbon cylinder 10. Therefore, when the disturbed airflow flows back and forth in the cavity 91, the hydrogen is intercepted and guided by the guide block 208, and the hydrogen is guided to the inner wall of the modified activated carbon cylinder 10 to improve the contact effect, thereby further improving the hydrogen adsorption efficiency. In addition, the guide blocks 208 are staggered, and the guide blocks 208 are aligned with the gaps between the two adjacent guide blocks 208 in front of them, thereby increasing the probability of the guide blocks 208 contacting the hydrogen flow, so that the guide blocks 208 can fully intercept and guide the hydrogen flowing out of the gaps, thereby helping to improve the hydrogen adsorption efficiency.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
