The airtightness detection unit comprises a transparent tube, a detection outer box body, a piston, a light source and a photosensitive element.

[0015] The beneficial effects of this invention are: 1. When the pressure sensor detects an abnormal pressure inside the sealing detection device, it first sends an alarm signal, then sends a signal to control the two sets of extension plates to extend from the guide cavity. At the same time, it sends a signal to control the inner detection plate to move the two sets of extension plates in the vertical direction. The first ultrasonic sensor set in the ring array captures the high-frequency sound waves generated by the turbulence at the leak point to achieve rapid location, which facilitates subsequent maintenance work. It can not only monitor the hydrogen storage tank in real time during operation, but also accurately and quickly determine the leak point, thus improving the effectiveness of the sealing detection device.

[0016] 2. By installing the installation and testing mechanism on top of the hydrogen storage tank, and then snapping two sets of sealing covers onto the top of the installation and testing mechanism, several sets of magnetic suction columns at the bottom of the two sets of sealing covers are then moved through into the corresponding sets of magnetic suction slots, so that the joints between the two sets of sealing covers and the two sets of installation covers are cross-shaped, preventing unstable snapping and device detachment. Then, four sets of abutment columns are controlled to extend from the corresponding telescopic slots and abut against the outer wall of the delivery pipe connected to the output end of the hydrogen storage tank, thereby achieving cavity sealing inside the sealing testing device. Moreover, the elastic telescopic plate can fit against the outer wall of delivery pipes of different sizes, improving the working stability of the sealing testing device while improving its compatibility.

[0017] 3. When the hydrogen storage tank is closed and no abnormalities are detected at the valves of the tank or the connection with the delivery pipeline, the two sets of winding wires are slowly extended, causing the outer detection plate to slowly descend. Through the reciprocating motion of the moving seat on the guide rail and the two sets of extension rails, the outer detection plate moves on the outer wall of the tank. The second ultrasonic sensor set in the array determines the leakage point on the outer wall of the tank, which facilitates subsequent maintenance work. At the same time, when hydrogen leakage occurs in the internal cavity of the installation detection mechanism, the outer detection plate can be lowered to the ground. The static electricity of the sealing detection device is released through the winding wires and several sets of conductor columns, which improves the detection effect of the sealing detection device and the working safety of the hydrogen storage tank.

[0018] 4. By controlling the electric actuator to move the transmission disc toward the valve switch of the hydrogen storage tank, several sets of transmission rods enter the valve switch. Then, the transmission rods are controlled to move away from the central axis of the transmission disc and abut against the inner wall of the valve switch. When the operator turns the rotating wheel, the torque sensor can detect the rotational torque of the electric actuator and control the auxiliary motor to apply torque to the electric actuator. This makes it easier for the operator to open and close the valve of the hydrogen storage tank. At the same time, when the operator is not present, the auxiliary motor can be controlled by a signal to drive the valve of the hydrogen storage tank to close. This improves the ease of use of the sealing detection device and reduces labor intensity.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention provides a sealing detection device for hydrogen energy storage equipment based on intelligent sensing, including a detection mounting mechanism 1. For example,... Figure 1 and Figure 2 As shown, the top of the installation and testing mechanism 1 is provided with an upper sealing mechanism 2; the outer wall of the installation and testing mechanism 1 is provided with an auxiliary testing mechanism 3; and the outer wall of the installation and testing mechanism 1 is provided with an auxiliary opening and closing mechanism 4.

[0025] The main leaks in the hydrogen storage tank are at the valves of the tank body and the connection with the delivery pipeline. The installation and detection mechanism 1 installs the sealing detection device at the output end of the hydrogen storage tank. The upper sealing mechanism 2 is connected to the installation and detection mechanism 1 to seal the valves of the hydrogen storage tank and the connection with the delivery pipeline to prevent hydrogen from leaking to the outside. When no hydrogen leak is detected at the valves of the hydrogen storage tank and the connection with the delivery pipeline, but the pressure inside the tank is abnormal, the detection mechanism 3 can assist the detection mechanism 3 in detecting the leak point on the outer wall of the hydrogen storage tank. The auxiliary opening and closing mechanism 4 is used to open and close the valve when no one is present or to assist personnel in opening and closing the valve.

[0026] For example, such as Figure 3 and Figure 4As shown, the installation and testing mechanism 1 includes two sets of symmetrically arranged installation covers 101; the top view of each set of installation covers 101 is a semi-circular ring shape, and several sets of magnetic suction slots 102 are equally spaced on the top; one set of installation covers 101 has an installation through slot 103 on its outer wall; the auxiliary opening and closing mechanism 4 is disposed in the installation through slot 103; the bottom inner wall of the other set of installation covers 101 is provided with a pressure sensor 104; two sets of guide rods 105 are symmetrically arranged on both sides of the pressure sensor 104; an inner detection plate 106 is movably sleeved on the outer wall of the two sets of guide rods 105; the top view interface of the inner detection plate 106 is a semi-circular ring shape; an extension plate 108 is movably passed through both ends of the inner detection plate 106; the top view interface of the extension plate 108 is a fan-shaped ring shape; the inner detection plate 106 and the two sets of extension rods 105 are connected to the outer wall of the two sets of guide rods 105. Several sets of first ultrasonic sensors 107 are arranged in a ring array on the inner wall of the extension plate 108; a set of limiting plates 109 are fitted on the bottom outer wall of each set of guide rods 105; a first lead screw 110 is provided between two sets of guide rods 105; the first lead screw 110 is threadedly connected to the inner detection plate 106; a guide cavity 111 is provided in the inner detection plate 106; the top view interface of the guide cavity 111 is semi-circular; one end of each set of extension plates 108 is movably inserted through the corresponding end of the guide cavity 111; several sets of guide gears 112 are evenly spaced on the inner wall of the guide cavity 111 away from the central axis of the inner detection plate 106; several sets of guide teeth 113 are evenly spaced on the outer wall of each set of extension plates 108; each set of guide gears 112 is meshed with the corresponding set of guide teeth 113.

[0027] During the use of the sealing detection device, the two sets of mounting covers 101 are first snapped onto the top output end of the hydrogen storage tank. Then, the two sets of limiting plates 109 are controlled to rotate and clamp onto the outer wall of the output port of the hydrogen storage tank. Under the sealing action of the upper sealing mechanism 2, when hydrogen leakage occurs, the pressure sensor 104 detects the abnormal pressure inside the sealing detection device and first sends an alarm signal. Then, a signal is sent to control the two sets of extension plates 108 to extend from the guide cavity 111. At the same time, a signal is sent to control the first lead screw 110 to rotate. Under the threaded connection between the first lead screw 110 and the inner detection plate 106, the inner detection plate 106 drives the two sets of extension plates 108 to move in the vertical direction. The first ultrasonic sensor 107, which is set in a ring array, captures the high-frequency sound waves generated by the turbulence at the leak point to achieve rapid positioning, which facilitates subsequent maintenance work. It can not only monitor the hydrogen storage tank in real time during operation, but also accurately and quickly determine the leak point, thus improving the effectiveness of the sealing detection device.

[0028] For example, such as Figure 5As shown, the upper sealing mechanism 2 includes two sets of symmetrically arranged sealing covers 201; the top view of each set of sealing covers 201 is a semi-circular cross section, and several sets of magnetic suction columns 202 are provided at equal intervals at the bottom; each set of magnetic suction columns 202 is movably inserted into a corresponding set of magnetic suction grooves 102; a set of connecting grooves 203 is opened at the top of each set of sealing covers 201; the two sets of connecting grooves 203 are combined to form a circular groove; two sets of telescopic grooves 204 are symmetrically opened at both ends of each set of sealing covers 201; a set of abutment columns 205 is movably inserted on the inner wall of the side of each set of telescopic grooves 204 near the connecting grooves 203; a set of elastic telescopic plates 206 are connected between the two sets of abutment columns 205; a folding sealing plate 207 is connected between each set of elastic telescopic plates 206 and the inner wall of the corresponding set of connecting grooves 203.

[0029] During the use of the sealing detection device, the installation detection mechanism 1 is first installed on the top of the hydrogen storage tank. Then, two sets of sealing covers 201 are snapped onto the top of the installation detection mechanism 1. Subsequently, several sets of magnetic suction columns 202 at the bottom of the two sets of sealing covers 201 are moved through into the corresponding set of magnetic suction grooves 102, so that the joints between the two sets of sealing covers 201 and the two sets of installation covers 101 are cross-shaped, preventing the device from falling off due to unstable snapping. Then, four sets of abutment columns 205 are controlled to extend from the corresponding telescopic grooves 204 and abut against the outer wall of the delivery pipe connected to the output end of the hydrogen storage tank, thereby achieving the sealing of the cavity inside the sealing detection device. Moreover, the elastic telescopic plate 206 can fit against the outer wall of delivery pipes of different sizes, which improves the working stability of the sealing detection device and improves its compatibility.

[0030] For example, such as Figure 6 As shown, the auxiliary detection mechanism 3 includes a guide rail 301; the guide rail 301 has a semi-circular cross-section when viewed from above, and each end is provided with a set of extension rails 302; the cross-section of each set of extension rails 302 when viewed from above is a fan-shaped annulus; the guide rail 301 and the two sets of extension rails 302 are respectively set on the outer wall of a corresponding set of mounting covers 101; a movable seat 303 is provided on the guide rail 301; a winding device 304 is provided on the side wall of the movable seat 303 away from the guide rail 301; the bottom of the winding device 304... A storage slot 305 is provided; two sets of winding wires 306 are symmetrically connected within the winding device 304; one end of each set of winding wires 306 away from the winding device 304 is connected to a storage column 307; the storage column 307 is frustum-shaped; an outer detection plate 308 is provided at the bottom of the storage column 307; several sets of conductor columns 309 are provided at the bottom edge of the outer detection plate 308; the top view interface of the outer detection plate 308 is fan-shaped, and several sets of second ultrasonic sensors 310 are distributed in a rectangular array on the inner wall.

[0031] During the use of the sealing detection device, when the hydrogen storage tank is closed but the internal gas pressure still changes, the valves of the tank and the connection with the delivery pipeline are first checked by the installation detection mechanism 1. If no abnormality is detected, the two sets of winding wires 306 are slowly extended, causing the outer detection plate 308 to slowly descend. The reciprocating motion of the moving seat 303 on the guide rail 301 and the two sets of extension rails 302 drives the outer detection plate 308 to move on the outer wall of the tank. The second ultrasonic sensor 310 arranged in an array determines the leakage point on the outer wall of the tank, which facilitates subsequent maintenance work. At the same time, when hydrogen leaks in the internal cavity of the installation detection mechanism 1, the outer detection plate 308 can be lowered to the ground. The static electricity of the sealing detection device is released by the winding wires 306 and several sets of conductor columns 309, which improves the detection effect of the sealing detection device and the working safety of the hydrogen storage tank.

[0032] For example, such as Figure 7 , Figure 8 and Figure 9 As shown, the auxiliary opening and closing mechanism 4 includes a mounting column 401; an electric push rod 402 is rotatably connected inside the mounting column 401; a transmission disk 404 is drive-connected to the output end of the electric push rod 402; a rotating wheel 403 is provided on the side wall of the mounting column 401 away from the transmission disk 404; the rotating wheel 403 is drive-connected to the electric push rod 402; several sets of sliding grooves 405 are arranged in a circular array on the side wall of the transmission disk 404 away from the electric push rod 402; a set of transmission rods 406 are slidably connected in each set of sliding grooves 405; an auxiliary cavity 407 is provided inside the mounting column 401; the auxiliary cavity 407... An auxiliary motor 408 is provided on one side wall of 07; a torque sensor is provided on the output end of the auxiliary motor 408 and is connected to the electric push rod 402; a set of second lead screws 409 are rotatably provided in each set of slide grooves 405; each set of second lead screws 409 is threadedly connected to a corresponding set of transmission rods 406; an external gear ring 410 is provided in the transmission disc 404; a bevel gear ring 411 is connected to the side wall of the external gear ring 410 near the slide groove 405; a set of bevel gears 412 are sleeved on the outer wall of each set of transmission rods 406; each set of bevel gears 412 is meshed with the bevel gear ring 411.

[0033] During the use of the sealing detection device, the electric push rod 402 is controlled to move the transmission disc 404 toward the valve switch of the hydrogen storage tank, causing several sets of transmission rods 406 to enter the valve switch. Subsequently, the external gear ring 410 is controlled to drive the bevel gear ring 411 to rotate. Under the meshing connection between the bevel gear ring 411 and several sets of bevel gears 412, the bevel gear ring 411 drives several sets of second lead screws 409 to rotate. Thus, under the threaded connection, the several sets of transmission rods 406 move away from the central axis of the transmission disc 404 and abut against the inner wall of the valve switch. When the operator turns the rotating wheel 403, the torque sensor can detect the rotational torque of the electric push rod 402 and control the auxiliary motor 408 to apply torque to the electric push rod 402, making it easier for the operator to open and close the valve of the hydrogen storage tank. At the same time, when the operator is not present, the auxiliary motor 408 can be controlled by a signal to drive the valve of the hydrogen storage tank to close, improving the ease of use of the sealing detection device and reducing labor intensity.

[0034] When the pressure sensor 104 detects an abnormal pressure inside the sealing detection device, it first sends an alarm signal, then sends a signal to control the two sets of extension plates 108 to extend from the guide cavity 111. At the same time, it sends a signal to control the inner detection plate 106 to move the two sets of extension plates 108 in the vertical direction. The first ultrasonic sensor 107, arranged in a ring array, captures the high-frequency sound waves generated by the turbulence at the leak point to achieve rapid location, which facilitates subsequent maintenance work. It can not only monitor the hydrogen storage tank in real time during operation, but also accurately and quickly determine the leak point, thus improving the effectiveness of the sealing detection device.

[0035] By installing the installation and detection mechanism 1 on the top of the hydrogen storage tank, and then snapping two sets of sealing covers 201 onto the top of the installation and detection mechanism 1, several sets of magnetic suction columns 202 at the bottom of the two sets of sealing covers 201 are then moved through into the corresponding set of magnetic suction grooves 102, so that the joints between the two sets of sealing covers 201 and the two sets of installation covers 101 are cross-shaped, preventing the device from falling off due to unstable snapping. Then, four sets of abutment columns 205 are controlled to extend from the corresponding telescopic grooves 204 and abut against the outer wall of the delivery pipe connected to the output end of the hydrogen storage tank, thereby achieving the sealing of the cavity inside the sealing detection device. Moreover, the elastic telescopic plate 206 can fit against the outer wall of delivery pipes of different sizes, which improves the working stability of the sealing detection device and improves its compatibility.

[0036] When the hydrogen storage tank is closed but the internal pressure is still changing, the valves of the tank and the connection with the delivery pipeline are first checked by the installation detection mechanism 1. If no abnormality is detected, the two sets of winding wires 306 are slowly extended, causing the outer detection plate 308 to slowly descend. The reciprocating motion of the moving seat 303 on the guide rail 301 and the two sets of extension rails 302 drives the outer detection plate 308 to move on the outer wall of the tank. The second ultrasonic sensor 310 arranged in an array determines the leakage point on the outer wall of the tank, which facilitates subsequent maintenance work. At the same time, when hydrogen leaks in the internal cavity of the installation detection mechanism 1, the outer detection plate 308 can be lowered to the ground. The static electricity of the sealing detection device is released by the winding wires 306 and several sets of conductor columns 309, which improves the detection effect of the sealing detection device and enhances the working safety of the hydrogen storage tank.

[0037] By controlling the electric push rod 402 to move the transmission disc 404 toward the valve switch of the hydrogen storage tank, several sets of transmission rods 406 enter the valve switch. Then, the several sets of transmission rods 406 are controlled to move away from the central axis of the transmission disc 404 and abut against the inner wall of the valve switch. When the operator turns the rotating wheel 403, the torque sensor can detect the rotational torque of the electric push rod 402 and control the auxiliary motor 408 to apply torque to the electric push rod 402. This makes it easier for the operator to open and close the valve of the hydrogen storage tank. At the same time, when the operator is not present, the auxiliary motor 408 can be controlled by a signal to drive the valve of the hydrogen storage tank to close. This improves the ease of use of the sealing detection device and reduces labor intensity.
