[0006] Sliders, a conduit is welded through the center of the two sliders, and the head ends of the two conduits are threadedly connected to a valve; valves, the head ends of the two valves are threadedly connected to a direct pipe, and the head ends of the two direct pipes are threadedly connected to a bent pipe; the bent pipe includes a gear sleeve, and the interior of the gear sleeve is provided with an internal thread, which is rotatably connected to the tail end of the bent pipe, and a circle of gear plates is provided on the circumferential outer wall of the two gear sleeves, and the two gear sleeves slide back and forth to engage with the four rows of gear plates on the four driving frames.

[0007] Preferably, the upper and lower ends of the slider are semi-cylindrical structures, and the four left and right springs of the two positioning shafts push and abut against the front and rear side surfaces of the slider.

[0008] Preferably, the valve comprises

[0009] The vertical support frame is welded and fixed to the top of the valve, and a limit plate is welded to the internal horizontal support of the vertical support frame;

[0010] A valve stem is inserted into the top support plate of the vertical support frame and the horizontal support limit plate inside the vertical support frame through spring pushing, and the lower half of the valve stem is inserted into the interior of the valve.

[0011] Preferably, a positioning ear plate is welded on one side of the top end of the vertical support frame close to the upper end plate, and a positioning mechanism is inserted through the positioning ear plate by spring pushing.

[0012] Preferably, the positioning mechanism includes

[0013] The insertion rod is a square structure and is the main part of the positioning mechanism;

[0014] A guide wheel is rotatably mounted on one end of the insertion rod close to the upper end plate, and the two guide wheels are in rolling contact with the inner end surfaces of the two track members.

[0015] Preferably, a slot is provided on the upper half of the valve stem, and the head end section of the plug rod is plugged into the slot.

[0016] Preferably, the method comprises the following steps:

[0017] 1. First, connect the two elbows to the two external hydrogenation guns through two hydrogen conducting hoses, and use the springs on the two sets of positioning shafts to keep the two sliders and two guide wheels centered;

[0018] 2. Then lift the two valve stems in turn, and insert the two valve stems into the upward sliding and withdrawing state through the two plug rods;

[0019] 3. From now on, the two valves are opened and the vehicle can be refilled with hydrogen.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention utilizes two drive frames and four rows of gears thereon. When the two sliders are forcibly pulled by the vehicle passing through the hydrogen filling gun and slide forward and backward along the two sets of positioning axes, they can be linked and meshed to drive the two gear sleeves to reverse and loosen, so that the two elbows and the hydrogen conducting hoses connected to the two elbows are automatically separated from the through-ducts on the two sliders, thereby preventing the hoses connected to the hydrogen filling gun from being pulled off when the vehicle is not properly disconnected from the hydrogen filling gun.

[0022] 2. The present invention uses the inclined guiding effect of the four inclined short rods on the two track members. When the two guide wheels follow the two sliders to slide, they can be pushed inward to drive the two plug rods to separate from the two valve stems, and control the two valve stems to automatically slide down and insert to close the two valves, thereby preventing the liquid hydrogen from spraying out from the through-ducts on the two sliders after the two elbows are pulled and separated, causing waste and safety hazards. The valve stems are indirectly driven and controlled to close automatically by the pulling force generated by the strong pulling of the vehicle, eliminating the trouble of manually controlling the opening and closing of the valves in the event of a pipe breakage accident. The strong pulling force is used to directly drive the valve to close, which has good timeliness and can make the valve close instantly when an accident occurs, greatly reducing the amount of hydrogen leakage and greatly reducing the safety hazards caused by hydrogen leakage.

[0023] 3. According to the present invention, when the hydrogenation gun and the hose are manually pulled, the two sliders can slide back and forth along the two sets of positioning axes, thereby extending the length of the hose connected to the hydrogenation gun and increasing the filling radius of the hydrogenation gun. The support frames at four locations can horizontally support and limit the sliding stroke of the two sliders, thereby preventing the two sliders from sliding significantly and contacting the teeth on the drive frame when the hydrogenation gun and the hose are manually pulled, thereby triggering the tripping and separation of the elbow, and ensuring that the elbow and valve breakage accident protection is not triggered when the pulling force is small. When a vehicle pulls the hydrogenation gun, since the support frame is a U-shaped structure, it has only one longitudinal support rod on one side and has low supporting strength. Driven by the severe pulling force, the two sliders can break or bend the four support frames to ensure that the elbow and valve breakage accident protection is triggered normally.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0035] Please refer to Figures 1 to 8 The present application provides an embodiment: a high-efficiency hydrogen filling device and a use method thereof, comprising a hydrogen filling machine 1; the hydrogen filling machine 1 comprises an upper end plate 101, and a polygonal upper end plate 101 is welded to the top end of the hydrogen filling machine 1 and supports the hydrogen filling machine 1; a rectangular mounting groove is formed through the left-right direction inside the upper end plate 101; four positioning shafts 104 are symmetrically welded to the left and right openings of the rectangular mounting groove inside the upper end plate 101, and a square sliding block 2 is top-pushed and sleeved on each of the two groups of positioning shafts 104 by a spring.

[0036] The sliding block 2, a conduit is welded through the center of each of the two sliding blocks 2, and a valve 3 is threadedly connected to the first end of each of the two conduits; the valve 3 comprises a vertical support frame 301, the vertical support frame 301 is welded and fixed to the top end of the valve 3, and a limiting plate is welded to the inside of the vertical support frame 301; a valve rod 302 is top-pushed and inserted through the top support plate of the vertical support frame 301 and the limiting plate inside the vertical support frame 301 by a spring, and the lower half of the valve rod 302 is inserted into the inside of the valve 3; a positioning ear plate is welded to the side of the top end of the vertical support frame 301 close to the upper end plate 101, and a positioning mechanism is top-pushed and inserted through the positioning ear plate by a spring; two hydrogen outlet pipes 106 are symmetrically welded and communicated to the bottom surface of the rectangular mounting groove inside the upper end plate 101, and the two hydrogen outlet pipes 106 are communicated with the through conduits on the two sliding blocks 2 through two hoses;

[0037] Valve 3, the head ends of the two valves 3 are threadedly connected to a direct pipe, and the head ends of the two direct pipes are threadedly connected to a bend pipe 4, and the two bend pipes 4 are connected to two external hydrogenation guns through two hydrogen-conducting hoses; the bend pipe 4 includes a gear sleeve 401, and the interior of the gear sleeve 401 is provided with an internal thread, which is rotatably connected to the tail end of the bend pipe 4, and a circle of gear plates is provided on the circumferential outer wall of the two gear sleeves 401, and the two gear sleeves 401 slide back and forth to engage with the four rows of gear plates on the four driving frames 102.

[0038] Furthermore, the hydrogenator 1 further includes a drive frame 102. Two drive frames 102 are welded symmetrically on the left and right sides of the upper end plate 101. Four rows of gear plates are symmetrically arranged on the four drive frames 102 in a vertically corresponding front-to-back manner. Through the two drive frames 102 and the four rows of gear plates thereon, the two sliders 2 can be linked and engaged when being strongly pulled by the vehicle through the hydrogenation gun to slide back and forth along the two sets of positioning shafts 104, so that the two gear sleeves 401 can be reversed and loosened, so that the two elbows 4 and the hydrogen-conducting hoses connected to the two elbows 4 are automatically separated from the through-ducts on the two sliders 2, thereby preventing the vehicle from breaking the hose connected to the hydrogenation gun when it is not normally disconnected from the hydrogenation gun, causing trouble for subsequent replacement and maintenance, and increasing maintenance costs;

[0039] The track member 103 is symmetrically welded with two track members 103 on the top of the left and right sides of the upper end plate 101, and the track member 103 is welded together by the middle rod, the inclined short rods at both ends of the middle rod, and the front and rear side support rods. Through the inclined guide effect of the four inclined short rods on the two track members 103, the two guide wheels 304 can be pushed inward when following the two sliders 2 to pull and slide, so that the two insertion rods 303 are separated from the two valve stems 302, and the two valve stems 302 are controlled to automatically slide down and insert the two valves. The door 3 is closed to prevent liquid hydrogen from spraying out from the through-ducts on the two sliders 2 after the two elbows 4 are disconnected and separated by strong pulling, causing waste and safety hazards. The valve stem 302 is indirectly driven and controlled to automatically close by the pulling force generated by the strong pulling of the vehicle, eliminating the trouble of manually controlling the opening and closing of the valve 3 in the event of a pipe breakage accident. The strong pulling force is used to directly drive the closing of the valve 3, which has good timeliness and can make the valve 3 close instantly when an accident occurs, greatly reducing the amount of hydrogen leakage and greatly reducing the safety hazards caused by hydrogen leakage.

[0040] Furthermore, the hydrogenation machine 1 further includes

[0041] The upper end plate 101 is internally provided with a rectangular mounting slot, and two V-shaped blocking frames 105 are symmetrically and tightly installed in the left and right openings of the rectangular mounting slot. The four blocking frames 105 can horizontally support and limit the sliding stroke of the two sliding blocks 2, so as to avoid the contact between the two sliding blocks 2 and the toothed blades on the driving frame 102 when the hydrogen gun and the hose are manually pulled, thereby triggering the trip separation of the elbow pipe 4, and ensuring that the trip separation of the elbow pipe 4 and the valve 3 will not be triggered when the pulling force is small. When the vehicle pulls the hydrogen gun, the blocking frame 105 has only one longitudinal support rod on one side due to the V-shaped structure, and the support strength is low. Under the action of the strong pulling force, the two sliding blocks 2 can break or bend the four blocking frames 105, so as to ensure the normal triggering of the trip separation of the elbow pipe 4 and the valve 3.

[0042] Further, the upper and lower ends of the sliding block 2 are in a semi-cylindrical structure, and the left and right four springs of the two positioning shafts 104 abut against and contact the front and rear sides of the sliding block 2. When the hydrogen gun and the hose are manually pulled, the two sliding blocks 2 can slide forward and backward along the two groups of positioning shafts 104, so as to expand the length of the hose connected with the hydrogen gun and increase the filling radius of the hydrogen gun.

[0043] Further, the positioning mechanism comprises a plug rod 303, which is a square structure and is the main part of the positioning mechanism; and a guide wheel 304, one end of the plug rod 303 close to the upper end plate 101 is rotatably installed with one guide wheel 304, and the inner side end surfaces of the two guide wheels 304 and the two track pieces 103 are in rolling abutment contact. A plug slot is formed in the upper half of the valve rod 302, and the leading end of the plug rod 303 is inserted and matched with the plug slot. The two plug rods 303 can insert and position the two valve rods 302 in the state of sliding away from the top, so that the two valves 3 remain open. When the two plug rods 303 are pulled away, the springs on the two valve rods 302 can automatically insert and push them, so as to close the two valves 3.

[0044] Further, the method comprises the following steps:

[0045] 1. First, connect the two elbow pipes 4 to the two external hydrogen guns through the two hydrogen guide hoses, and keep the two sliding blocks 2 and the two guide wheels 304 centered by the springs on the two groups of positioning shafts 104.

[0046] 2. Then, sequentially lift the two valve rods 302, and insert and position the two valve rods 302 in the state of sliding away from the top through the two plug rods 303.

[0047] 3. From now on, the two valves 3 are opened, and the vehicle can be filled with hydrogen.

[0048] In another embodiment, a steel wire rope can be welded between the front and rear short support plates of the two retaining frames 105. The steel wire rope can pull the front and rear short support plates connecting the two retaining frames 105 to prevent the two retaining frames 105 from flying and injuring people after being broken by impact, thereby reducing safety hazards to personnel in the event of an accident.

[0049] Working principle: When the two sliders 2 are pulled forcefully by the vehicle through the hydrogen filling gun and slide forward and backward along the two sets of positioning shafts 104, the two four-way driving frames 102 and the four rows of gears thereon can be meshed to drive the two gear sleeves 401 to reverse and loosen, so that the two elbows 4 and the hydrogen-conducting hoses connected to the two elbows 4 are automatically separated from the through-ducts on the two sliders 2, preventing the hoses connected to the hydrogen filling gun from being pulled off when the vehicle is not properly disconnected from the hydrogen filling gun;

[0050] When the two guide wheels 304 follow the two sliders 2 and slide, they can be guided by the inclined surfaces of the four inclined short rods on the two track members 103 to push inward to drive the two plug rods 303 to separate from the two valve stems 302. When the two plug rods 303 are pulled out, the springs on the two valve stems 302 can automatically push them down to close the two valves 3, thereby preventing the two elbows 4 from spraying out of the through-ducts on the two sliders 2 after being forcibly pulled off.

[0051] When the hydrogenation gun and the hose are pulled manually, the two sliders 2 can slide back and forth along the two sets of positioning shafts 104, extending the length of the hose connected to the hydrogenation gun and increasing the filling radius of the hydrogenation gun. The support frames 105 at four locations can horizontally support and limit the sliding stroke of the two sliders 2 to prevent the two sliders 2 from sliding significantly and contacting the teeth on the drive frame 102 when the hydrogenation gun and the hose are pulled manually, triggering the tripping and separation of the bend pipe 4, and ensuring that the pipe breaking accident protection of the bend pipe 4 and the valve 3 will not be triggered when the pulling force is small. When a vehicle pulls the hydrogenation gun, since the support frame 105 is a U-shaped structure, it has only one longitudinal support rod on one side and the supporting strength is low. Driven by the severe pulling force, the two sliders 2 can break or bend the support frames 105 at four locations to ensure that the pipe breaking accident protection of the bend pipe 4 and the valve 3 is triggered normally.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
