[0028] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0029] Reference will be made below to Figures 1 - 5 describe the gas cylinder protection device 1 according to an embodiment of the present utility model.

[0030] The gas cylinder protection device 1 according to an embodiment of the present utility model, as Figure 1As shown, the gas cylinder protection device 1 may include: a protection frame 10, a protection airbag 20 and a starter 30. The protection frame 10 is used to be mounted on the gas cylinder 2, the protection airbag 20 is arranged on the protection frame 10, and the starter 30 is arranged on the protection frame 10. The starter 30 is connected to the protection airbag 20, and the starter 30 selectively drives the protection airbag 20 to work so that the protection airbag 20 is filled with gas.

[0031] It should be noted that as the gas cylinder is moving towards the goal of lightweight, the relative strength and rigidity of the gas cylinder will inevitably decrease. If the gas cylinder falls, it is easy to cause damage to the gas cylinder. The existing gas cylinder protection device cannot effectively protect the gas cylinder, and there are safety hazards when the gas cylinder is in use.

[0032] Based on this, the embodiment of the present application proposes a gas cylinder protection device 1. Along the length direction of the gas cylinder 2, from one end of the gas cylinder 2 to the other end of the gas cylinder 2, a protection frame 10 is sleeved on the outside of the gas cylinder 2, and the protection frame 10 can support the gas cylinder 2. Figure 1 When setting the direction, the length direction of cylinder 2 is Figure 1 The Y direction in the figure. The protective airbag 20 is arranged on the protective frame 10. The protective airbag 20 can be arranged at any position of the protective frame 10. The protective airbag 20 can be arranged on the protective frame 10 by means of snap connection, bonding, etc. For example, the protective airbag 20 can be sleeved on the protective frame 10, which is helpful to prevent the protective airbag 20 from falling off the protective frame 10, and ensure that the protective airbag 20 can play a role when the gas cylinder 2 falls. When the gas cylinder 2 falls, the protective airbag 20 can be filled with gas and expand, and the protective airbag 20 can protrude from the protective frame 10. The protective airbag 20 is impacted before the gas cylinder 2, and the protective airbag 20 can achieve a buffering effect. At least a part of the protective airbag 20 can be arranged on the side of the protective frame 10 away from the gas cylinder 2, so as to play a buffering role.

[0033] The starter 30 is arranged on the protection frame 10. The starter 30 can be fixed on the protection frame 10 by means of clamping, bolt connection, etc. The starter 30 can be electrically connected, communicated, etc. with the protection airbag 20. The starter 30 can drive the protection airbag 20 to work so that the protection airbag 20 is filled with gas. The starter 30 can selectively drive the protection airbag 20 to work. When the gas cylinder 2 is safely placed, the starter 30 does not work, and the protection airbag 20 does not work. When the gas cylinder 2 falls, the starter 30 can drive the protection airbag 20 to work, the protection airbag 20 is inflated, and the protection airbag 20 expands. The protection airbag 20 can play a role in mitigating the impact, thereby achieving a protective effect on the gas cylinder 2, ensuring the safety of the gas cylinder 2 when in use, and helping to extend the service life of the gas cylinder 2.

[0034] In some embodiments of the present invention, there are multiple protection airbags 20 , and the multiple protection airbags 20 are respectively disposed at different positions of the protection frame 10 .

[0035] There can be multiple airbags 20. The multiple airbags 20 can be distributed along the length direction of the gas cylinder 2, the multiple airbags 20 can be distributed along the radial direction of the gas cylinder 2, and the multiple airbags 20 can be arranged at different positions of the protection frame 10 to protect key parts of the gas cylinder 2. When the gas cylinder 2 drops, the multiple airbags 20 can be inflated and expanded simultaneously, so as to achieve multi-directional protection of the gas cylinder 2. By providing multiple airbags 20, the impact force received by the gas cylinder 2 when it drops can be reduced, the damage suffered by the gas cylinder 2 can be minimized, which is beneficial to enhancing the protection effect of the gas cylinder protection device 1 on the gas cylinder 2 and improving the safety during the use of the gas cylinder 2.

[0036] In some embodiments of the present utility model, as Figure 2 shown, the airbag 20 may include: an airbag body 21 and a gas generating structure 22. The gas generating structure 22 is arranged inside the airbag body 21, and the initiator 30 selectively drives the gas generating structure 22 to work.

[0037] The airbag body 21 can be made of polymer materials such as polyamide fiber and polyester fiber. These materials have characteristics such as light weight, high strength, and tear resistance. When the airbag 20 is filled with gas, the airbag body 21 unfolds, so as to achieve the effect of the expansion of the airbag 20. The gas generating structure 22 is arranged inside the airbag body 21. The gas generating structure 22 can release gas. The gas generating structure 22 may include a gas generating substance. As an example, the gas generating substance can be sodium azide, ammonium nitrate or a combination of both. When the gas cylinder 2 drops, the gas generating structure 22 releases gas, so that the airbag body 21 is filled with gas, thereby causing the airbag 20 to expand.

[0038] The initiator 30 can be connected to the gas generating structure 22. The initiator 30 can selectively drive the gas generating structure 22 to work. When the gas cylinder 2 is placed safely, the initiator 30 does not work, and the gas generating structure 22 does not work either. When the gas cylinder 2 drops, the initiator 30 can drive the gas generating structure 22 to work, so that the gas generating structure 22 releases gas. As an example, the initiator 30 can be connected to the gas generating structure 22 through an igniter 23. The igniter 23 can be arranged inside the airbag body 21. When the gas cylinder 2 drops, the initiator 30 can drive the igniter 23 to ignite. The igniter 23 ignites to start the gas generating structure 22. The gas generating substance inside the gas generating structure 22 decomposes rapidly and releases gas, so that the airbag body 21 is filled with gas, causing the airbag 20 to expand.

[0039] In some embodiments of the present utility model, as Figure 2As shown, the airbag 20 may further include: a housing 24, the housing 24 is fixedly provided on the protection frame 10, the airbag body 21 and the gas generating structure 22 are both arranged inside the housing 24, and the housing 24 is configured to crack when the starter 30 drives the gas generating structure 22 to work.

[0040] The housing 24 can be fixedly provided on the protection frame 10 by means of snap connection, bolt connection, etc., so that the airbag 20 is fixedly provided on the protection frame 10 to prevent the airbag 20 from falling off the protection frame 10. When the airbag 20 is not working, the airbag body 21 and the gas generating structure 22 are both arranged inside the housing 24. When the gas cylinder 2 drops and the starter 30 drives the gas generating structure 22 to work, the gas generating structure 22 can release gas to fill the airbag body 21 with gas, and the housing 24 can crack so that the airbag 20 can expand smoothly, which is beneficial to ensuring the practicability of the airbag 20. As an example, the housing 24 can be provided with a notch, and when the airbag 20 expands, the housing 24 can crack from the notch so that the airbag 20 can expand smoothly.

[0041] In some embodiments of the present invention, as Figure 5 shown, the starter 30 may include: a gravity sensor 31 and / or a pressure detector 32. The gravity sensor 31 is used to detect the gravitational acceleration of the gas cylinder protection device 1 falling, and the pressure detector 32 is used to detect the gas pressure in the gas cylinder 2. The starter 30 is configured to drive the airbag 20 to work according to the detection information of the gravity sensor 31 and / or the detection information of the pressure detector 32.

[0042] The starter 30 may include a gravity sensor 31, or the starter 30 may include a pressure detector 32, or the starter 30 may include a gravity sensor 31 and a pressure detector 32. The gravity sensor 31 can detect the gravitational acceleration of the gas cylinder protection device 1 falling, and the pressure detector 32 can detect the gas pressure in the gas cylinder 2. The starter 30 can drive the airbag 20 to work according to the detection information of the gravity sensor 31, or the starter 30 can drive the airbag 20 to work according to the detection information of the pressure detector 32, or the starter 30 can drive the airbag 20 to work according to the detection information of the gravity sensor 31 and the detection information of the pressure detector 32. In the embodiments of the present application, an example is given that the starter 30 includes a gravity sensor 31 and a pressure detector 32, and the starter 30 drives the airbag 20 to work according to the detection information of the gravity sensor 31 and the detection information of the pressure detector 32. When the gas cylinder 2 drops, the gravity sensor 31 can detect the gravitational acceleration of the gas cylinder protection device 1 falling. When the pressure detector 32 detects that the gas pressure in the gas cylinder 2 is higher than the set value, the pressure detector is in an activated state. When the pressure detector 32 detects that the gas pressure in the gas cylinder 2 is lower than the set value, the pressure detector 32 is in an unactivated state.

[0043] The starter 30 can drive the airbag 20 to work according to the detection information of the gravity sensor 31 and the detection information of the pressure detector 32. When the pressure detector 32 detects that the gas pressure in the gas cylinder 2 is higher than the set value, the pressure detector 32 is in an activated state, and when the gas cylinder 2 drops and the gravity sensor 31 detects the gravitational acceleration of the gas cylinder protection device 1 falling, the starter 30 responds quickly. The starter 30 drives the gas generating structure 22 in the airbag 20 to release gas, causing the airbag 20 to expand. When the pressure detector 32 detects that the gas pressure in the gas cylinder 2 is lower than the set value, the pressure detector 32 is in an unactivated state, and the starter 30 does not work. When the gravity sensor 31 does not detect the gravitational acceleration of the gas cylinder protection device 1 falling, the starter 30 does not work.

[0044] In some embodiments of the present invention, as Figure 5 shown, the starter 30 includes a power supply 33, a gravity sensor 31 and a pressure detector 32. The power supply 33, the pressure detector 32, the airbag 20 and the gravity sensor 31 are connected in series.

[0045] The starter 30 may further include a power supply 33. The starter 30 may include a gravity sensor 31 and a pressure detector 32. The power supply 33, the pressure detector 32, the gravity sensor 31 and the igniter 23 of the airbag 20 are connected in series, and multiple igniters 23 are connected in parallel. When the circuit is connected, the effect that the starter 30 can drive multiple airbags 20 to inflate and expand simultaneously can be achieved, so as to realize the multi-directional protection of the gas cylinder 2 by multiple airbags 20. When the pressure detector 32 detects that the gas pressure in the gas cylinder 2 is higher than the set value, the pressure detector 32 is in an activated state, and the series circuit is connected. When the pressure detector 32 detects that the gas pressure in the gas cylinder 2 is lower than the set value, the pressure detector is in an unactivated state, the series circuit is disconnected, the starter 30 does not work, and the gas cylinder protection device 1 does not work. According to the detection information of the pressure detector 32, the disconnection or connection of the series circuit in the starter 30 can be controlled, which is beneficial to saving the energy of the power supply 33, thereby prolonging the service life of the gas cylinder protection device 1, and the mis-start rate of the starter 30 is low, safe and reliable.

[0046] There may be multiple airbags 20. Multiple airbags 20 can all be connected in series with the starter 30, and multiple airbags 20 are connected in parallel. Wires are connected between multiple airbags 20 and the starter 30. As an example, the wires can be wound around the protection frame 10 to prevent the wires from falling off. As another example, the protection frame 10 can be constructed as a hollow structure, and the wires can be arranged inside the protection frame 10, which is beneficial to reducing the weight of the protection frame 10, protecting the wires from being eroded by the external environment, and prolonging the service life of the wires.

[0047] When the pressure detector 32 detects that the gas pressure in the gas cylinder 2 is higher than the set value, the pressure detector 32 is in an activated state, and the internal circuit of the starter 30 is connected. When the gas cylinder 2 drops and the gravity sensor 31 detects the gravitational acceleration of the gas cylinder protection device 1 falling, the starter 30 responds quickly. The starter 30 drives the igniters 23 of multiple protection airbags 20 to ignite. The igniters 23 ignite to start the gas generating structure 22. The gas generating substance in the gas generating structure 22 decomposes rapidly and releases gas, so that the multiple airbag bodies 21 are filled with gas, and the multiple protection airbags 20 expand, thereby realizing the multi-directional protection effect of the gas protection device 1 on the gas cylinder 2.

[0048] In some embodiments of the present utility model, as Figure 1 shown, the protection frame 10 may include: a first end frame 11, a middle frame 12, and a second end frame 13.

[0049] The first end frame 11 and the second end frame 13 are arranged opposite to each other along the length direction of the gas cylinder 2 and are spaced apart.

The first end frame 11, the middle frame 12, and the second end frame 13 jointly define the installation space, and the gas cylinder 2 is installed in the installation space, thereby realizing the effect that when the gas cylinder 2 drops, the gas cylinder protection device 1 can protect the gas cylinder 2.

[0050] The protection frame 10 is constructed as a split structure, which is convenient for the loading, unloading, and replacement of the protection frame 10. If one of the first end frame 11, the middle frame 12, and the second end frame 13 is damaged, the damaged parts can be replaced separately, which is beneficial to cost saving.

[0051] As an example, protection airbags 20 can be provided on both the first end frame 11 and the second end frame 13, so as to realize the multi-directional protection of the gas cylinder 2 by the multiple protection airbags 20, which is beneficial to enhancing the protection effect of the gas cylinder protection device 1 on the gas cylinder 2 and improving the safety of the gas cylinder 2 during use.
