Description

Technical Field

[0001] The invention relates to the technical field of gas storage containers, in particular to a device with a gas leakage emergency locking function. Background Art

[0002] Gas cylinders, also known as gas tanks, are gas storage containers that are mainly used in outdoor catering, such as roadside snack stands. If the cylinder is not properly handled, safety accidents such as fire or explosion may occur. Therefore, the cylinder needs to be equipped with a leak-proof blocking device. When the cylinder leaks accidentally, the valve of the cylinder should be closed in time to prevent the gas from leaking further.

[0003] Existing bottle leakage prevention and blocking devices are mostly electric valves installed on gas pipelines. When the gas concentration alarm detects a gas leak, the electric valve is triggered to shut off the gas pipeline. This type of gas shut-off device requires disassembly of the pipeline, which may become a new gas leak point if not properly operated. Summary of the invention

[0042] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0043] like Figure 1-Figure 12 As shown, a device with a gas leakage emergency locking function is installed on the bottle body of the gas bottle, including an annular connecting frame 100, a limit mounting frame 200, a motor 300, a connecting sleeve 410 and a transmission sleeve 420. The annular connecting frame 100 is coaxially fixedly installed above the bottle body. An annular groove is opened at the upper end of the annular connecting frame 100. Two blocking sheets 110 are arranged at equal intervals in the circumferential direction of the annular groove. The blocking sheets 110 isolate the annular groove into two semi-grooves 120 that are not connected to each other. The two ends of the limit mounting frame 200 are rotatably connected in the two semi-grooves 120 respectively. The motor 300 is fixedly installed on the limit mounting frame 200. The output shaft of the motor 300 is coaxial with the rotating valve of the bottle body 1000. The connecting sleeve 410 is coaxially fixedly connected to the rotating valve of the bottle body 1000, the transmission sleeve 420 is coaxially sleeved with the connecting sleeve 410, the transmission sleeve 420 and the connecting sleeve 410 can rotate synchronously and move relative to each other along the axis of the transmission sleeve 420, the transmission sleeve 420 is also coaxially sleeved with the output shaft of the motor 300, the transmission sleeve 420 and the output shaft of the motor 300 can rotate synchronously and move relative to each other along the axis of the transmission sleeve 420, a one-way transmission assembly 500 is provided between the transmission sleeve 420 and the limit mounting frame 200, and the one-way transmission assembly 500 is configured so that when the transmission sleeve 420 rotates counterclockwise, the limit mounting frame 200 can be driven to rotate synchronously through the one-way transmission assembly 500.

[0044] When the combustion bottle is in normal use, when it is necessary to open the rotating valve of the bottle body 1000, the staff rotates the transmission sleeve 420 counterclockwise, and the transmission sleeve 420 drives the connecting sleeve 410 to rotate synchronously, and the connecting sleeve 410 drives the rotating valve of the bottle body 1000 to rotate synchronously. At the same time, the transmission sleeve 420 drives the limit mounting frame 200 to rotate counterclockwise synchronously through the one-way transmission component 500. When the two ends of the limit mounting frame 200 rotate to abut against the blocking piece 110, the counterclockwise rotation angle of the rotating valve reaches 180 degrees, and the rotating valve is fully opened;

[0045] When the incendiary bottle is in normal use and the valve of the bottle body 1000 needs to be closed, the staff rotates the limit mounting frame 200 clockwise, and the limit mounting frame 200 drives the transmission sleeve 420 to rotate clockwise through the one-way transmission assembly 500, and the transmission sleeve 420 drives the connecting sleeve 410 to rotate clockwise, and the connecting sleeve 410 drives the rotating valve to rotate clockwise. When the limit mounting frame 200 rotates clockwise until it abuts against the blocking piece 110 on the opposite side, it means that the rotating valve has rotated 180 degrees clockwise and the rotating valve is completely closed.

[0046] Under abnormal conditions, when the rotary valve is in the open state, if the gas concentration alarm sounds, the gas concentration alarm sends an electrical signal to the motor 300, and the output shaft of the motor 300 rotates clockwise. The rotation of the motor 300 causes the limit mounting bracket 200 to rotate counterclockwise relative to the output shaft of the motor 300 until the limit mounting bracket 200 abuts against the blocking plate 110. Then, as the motor 300 continues to rotate, the output shaft of the motor 300 drives the transmission sleeve 420 to rotate clockwise, and the transmission sleeve 420 drives the connecting sleeve 410 to rotate clockwise, and the connecting sleeve 410 drives the rotary valve to rotate clockwise, thereby closing the rotary valve. Compared with the existing gas shut-off device, this device does not need to disassemble the pipeline during installation, but directly controls the rotation state of the rotary valve, and has higher safety and reliability.

[0047] It should be supplemented that the connecting sleeve 410 and the transmission sleeve 420 , as well as the transmission sleeve 420 and the output shaft of the motor 300 , are all matched with each other by a spline structure so that the two can rotate synchronously and move relatively along the axis of the transmission sleeve 420 .

[0048] It should also be noted that the thickness of the blocking sheet 110 should be as small as possible, so that the limiting mounting frame 200 can rotate clockwise or counterclockwise at an angle approximately equal to 180 degrees.

[0049] It should also be noted that the gas concentration alarm in the device can be arranged on the bottle body 1000 to detect the gas concentration around the bottle body 1000, and the gas concentration alarm is connected to the motor 300 signal.

[0050] It should also be noted that sliding guide pillars are provided on the lower surfaces of both ends of the limiting mounting frame 200, and the sliding guide pillars are slidably connected in the half grooves 120, so that the two ends of the limiting mounting frame 200 are respectively rotatably connected in the two half grooves 120.

[0051] In a further embodiment, Figure 5 and Figure 6 As shown, the one-way transmission assembly 500 includes a ratchet 510, an extension plate 530 and a ratchet 520. The ratchet 510 is coaxially fixed to the upper part of the transmission sleeve 420, and the extension plate 530 is arranged at the lower end of the limit mounting frame 200. The ratchet 520 is rotatably connected to the extension plate 530. A connecting spring (not shown in the figure) is provided between the ratchet 520 and the extension plate 530. The ratchet 520 is configured so that when the ratchet 510 rotates counterclockwise, the ratchet 520 and the ratchet 510 are blocked.

[0052] When the rotating valve is opened normally, the transmission sleeve 420 is rotated counterclockwise, the transmission sleeve 420 drives the connecting sleeve 410 to rotate counterclockwise, and the connecting sleeve 410 drives the rotating valve to rotate counterclockwise, thereby opening the valve. At the same time, the transmission sleeve 420 drives the ratchet 510 to rotate counterclockwise, and the ratchet 510 drives the extension plate 530 to rotate counterclockwise through the ratchet teeth 520, and the extension plate 530 drives the limit mounting frame 200 to rotate counterclockwise.

[0053] When the rotating valve is closed normally, the staff rotates the limit mounting frame 200 clockwise, the limit mounting frame 200 drives the extension plate 530 to rotate clockwise, the extension plate 530 drives the ratchet 520 to rotate clockwise, the ratchet 520 drives the ratchet wheel 510 to rotate clockwise, the ratchet wheel 510 drives the transmission sleeve 420 to rotate clockwise, the transmission sleeve 420 drives the connecting sleeve 410 to rotate clockwise, the connecting sleeve 410 drives the rotating valve of the bottle body 1000 to rotate clockwise, thereby closing the rotating valve.

[0054] When the gas concentration alarm sends an electrical signal to the motor 300, the motor 300 rotates clockwise. The rotation of the motor 300 causes the limit mounting frame 200 to rotate clockwise first until the limit mounting frame 200 abuts against the blocking plate 110. Then, as the motor 300 continues to rotate, the motor 300 drives the transmission sleeve 420 to rotate, the transmission sleeve 420 drives the connecting sleeve 410 to rotate clockwise, and the connecting sleeve 410 drives the rotating valve to rotate clockwise, thereby closing the rotating valve. Since the ratchet 520 is configured so that when the ratchet 510 rotates counterclockwise, the ratchet 520 and the ratchet 510 are blocked. Therefore, when the transmission sleeve 420 rotates clockwise, the transmission sleeve 420 drives the ratchet 510 to rotate clockwise. The clockwise rotation of the ratchet 510 causes the ratchet 520 to rotate away from the ratchet 510, thereby compressing the connecting spring, so that the ratchet 510 and the transmission sleeve 420 can rotate clockwise to close the rotating valve.

[0055] The bottle body 1000 in the device is automatically activated only when there is a gas leak. Under normal circumstances, the rotating valve can be opened or closed manually, so it is more suitable for outdoor working environments.

[0056] In a further embodiment, Figure 6 As shown, two manual handles 540 are circumferentially and evenly spaced at the upper end of the ratchet 510 , and the manual handles 540 extend outwardly in the radial direction of the ratchet 510 .

[0057] In order to facilitate the staff to rotate the transmission sleeve 420, a manual handle 540 is provided. When the transmission sleeve 420 needs to be rotated, the staff can drive the transmission sleeve 420 to rotate by holding the manual handle 540.

[0058] In a further embodiment, Figure 6 As shown, a reset component 600 is also provided on the extension plate 530. The reset component 600 is used to reset the relative position relationship between the limit mounting frame 200 and the rotating valve of the bottle body 1000 after the output end of the motor 300 rotates and then closes the rotating valve of the combustion bottle 1000.

[0059] When the rotating valve is closed by rotating the motor 300, the position of the limit mounting frame 200 is at the position when the rotating valve is normally opened. Therefore, the position of the limit mounting frame 200 is not synchronized with the position of the rotating valve when it is normally closed, and the transmission sleeve 420 always rotates synchronously with the rotating valve. The relative position relationship between the limit mounting frame 200 and the rotating valve of the bottle body 1000 needs to be reset by the reset assembly 600.

[0060] In a further embodiment, Figure 7 , Figure 8 and Fig.12As shown, the reset assembly 600 includes a bevel block 610 and a side block 620, a mounting cavity 531 is provided in the extension plate 530, and a first slot 532 is provided in the extension plate 530 toward the center of the annular connecting frame 100, the bevel block 610 is slidably connected in the first slot 532, a first tension spring 533 is provided in the mounting cavity 531, and one end of the first tension spring 533 away from the mounting cavity 531 is fixedly connected to the bevel block 610, a second slot 534 is provided on the side of the bevel block 610, and the side block 620 is slidably connected in the second slot 534, and the side block 620 abuts against the bevel block 610, and when the side block 620 moves into the mounting cavity 531, the side block 620 pushes the bevel block 610 to make the bevel block 610 slide into the mounting cavity 531, and the side block 620 can abut against the manual handle 540.

[0061] When resetting, the staff pulls the transmission sleeve 420 upward along the axis of the transmission sleeve 420, so that the transmission sleeve 420 is disengaged from the connecting sleeve 410. At the same time, the ratchet 510 and the ratchet teeth 520 are disengaged from the blocking cooperation. At this time, the ratchet 510 is located above the inclined block 610. Then the transmission sleeve 420 is rotated clockwise. The transmission sleeve 420 is fixedly connected to the manual handle 540 thereon to push the limit mounting frame 200 to rotate clockwise. When the limit mounting frame 200 rotates clockwise until it abuts against the blocking piece 110, the transmission sleeve 420 continues to be rotated clockwise, which will cause the manual handle 540 to apply pressure to the side block 620, so that the side block 620 moves into the mounting cavity 531. The side block 620 pushes the inclined block 610 through the inclined surface, so that the inclined block 610 also moves into the installation cavity 531, and the first tension spring 533 is gradually stretched. When the inclined block 610 moves to a position where it no longer hinders the transmission sleeve 420 from moving downward, the transmission sleeve 420 moves downward to a position where the transmission sleeve 420 is matched with the connecting sleeve 410 and connected. At the same time, the ratchet 510 and the ratchet 520 are also in a position that can stop the cooperation. At this time, the limit mounting frame 200 is in the clockwise rotation limit position (that is, the position where the rotating valve is fully closed), and the rotating valve is also in a closed state. Next, the limit mounting frame 200 is rotated counterclockwise to open the rotating valve of the bottle body 1000.

[0062] In a further embodiment, Figure 3 As shown, a connection assembly 700 is provided between the annular connection frame 100 and the bottle body 1000 , and the connection assembly 700 is used to coaxially fix the annular connection frame 100 on the top of the bottle body 1000 .

[0063] In a further embodiment, Figure 5As shown, the connecting assembly 700 includes a rotating disk 710, a sliding column 720, a clamping rod 730 and a limit frame 740. The rotating disk 710 is coaxially rotatably connected in the annular connecting frame 100. The rotating disk 710 can rotate around its axis. A plurality of arc-shaped waist grooves 750 are circumferentially and evenly spaced. The sliding column 720 is slidably connected in the arc-shaped waist grooves 750. The lower end of the sliding column 720 is fixedly connected to the clamping rod 730. The limit frame 740 is arranged at the lower end of the annular connecting frame 100. The clamping rod 730 is slidably connected to the limit frame 740 so that the clamping rod 730 can move in the radial direction of the rotating disk 710.

[0064] When the annular connecting frame 100 needs to be coaxially fixedly installed above the bottle body 1000, the staff drives the rotating disk 710, and drives the clamping rod 730 to move toward the direction close to the axis of the bottle body 1000 through the sliding cooperation of the arc waist groove 750 and the sliding column 720, so that the annular connecting frame 100 and the bottle body 1000 are fixedly connected together, so that it can adapt to bottles 1000 of different sizes.

[0065] In a further embodiment, Figure 5 As shown, a side clamping block 760 is provided on the inner side of the clamping rod 730 . The side clamping block 760 is a rubber block. The side clamping block 760 is provided to increase the clamping force between the side clamping block 760 and the bottle body 1000 .

[0066] In a further embodiment, Figure 5 As shown, a connection hole 731 is provided on the side of the clamping rod 730 and below the side clamping block 760 , and a bottom clamping block 770 is provided in the connection hole 731 .

[0067] The bottom clamping block 770 is provided to increase the clamping force between the bottom clamping block 770 and the bottle body 1000 , and further enhance the connection stability between the clamping rod 730 and the bottle body 1000 .

[0068] In a further embodiment, Figure 5 As shown, a thread groove 130 is provided on the annular connecting frame 100, and the thread groove 130 penetrates the annular connecting frame 100. A lead screw 140 is threadedly connected to the thread groove 130, and a threaded slider 150 is threadedly connected to the lead screw 140. A guide groove 780 is provided on the rotating disk 710, and a rotating block 160 is rotatably connected to the lower end of the threaded slider 150, and the rotating block 160 is slidably connected in the guide groove 780.

[0069] When the rotating disk 710 needs to be rotated, the staff rotates the screw 140 so that the threaded slider 150 drives the rotating block 160 to move along the guide groove 780 toward the center of the rotating disk 710, thereby driving the rotating disk 710 to rotate, and then the clamping rod 730 moves toward the center of the bottle body 1000, so that the clamping rod 730 can be fixed on the bottle body 1000.

[0070] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
