[0046] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0047] The following will Figures 1 - 6 , through specific embodiments and their application scenarios, provide a detailed description of the gas leakage prevention device provided by the invention embodiments.

[0048] As Figure 1 shown, an embodiment of the present utility model provides a gas leakage prevention device, including: a mobile carrier 1, a clamping assembly 2, a robotic arm 3, and a screwing assembly 4;

[0049] The mobile carrier 1 is configured to be able to move to the area where the leaking gas cylinder 400 is located;

[0050] The clamping assembly 2 is provided on the mobile carrier 1 to clamp and fix the gas cylinder 400;

[0051] The robotic arm 3 is provided on the mobile carrier 1 and is connected to the screwing assembly 4; the robotic arm 3 is used to control the screwing assembly 4 to reach the position of the valve stem of the gas cylinder 400, and the screwing assembly 4 is used to drive the valve stem of the valve to rotate to control the valve to close.

[0052] It can be understood that the mobile carrier 1 can be an electric vehicle, for example, the electric vehicle is a remote control vehicle; when special gases such as hydrogen, oxygen, nitrogen, argon, helium, or silane gas stored in the gas cylinder 400 leak, the mobile carrier 1 can carry the clamping assembly 2 and the robotic arm 3 and move to one side of the gas cylinder 400.

[0053] The clamping assembly 2 can adopt an electric gripper or a pneumatic gripper. The clamping assembly 2 is used to clamp the peripheral wall of the gas cylinder 400 to ensure that the gas cylinder 400 does not shake during the process of the screwing assembly 4 driving the valve stem of the valve to rotate; the robotic arm 3 can adopt a multi-degree-of-freedom robotic arm 3 such as a three-axis robotic arm 3 or a six-axis robotic arm 3 to adjust the position and posture of the screwing assembly 4 based on the robotic arm 3, so as to ensure that the screwing assembly 4 is connected to the valve stem of the valve at a suitable angle and drives the valve stem to rotate relative to the body of the valve.

[0054] In practical applications, when the mobile carrier 1 moves to one side of the gas cylinder 400 and a valve closing operation needs to be performed on the gas valve, first, the clamping assembly 2 clamps on the peripheral wall of the gas cylinder 400, and then the robotic arm 3 adjusts the position and posture of the screwing assembly 4; after the screwing assembly 4 is connected to the valve stem of the gas valve, the screwing assembly 4 drives the valve stem of the gas valve to rotate until the closing control of the gas valve is completed.

[0055] As can be seen from the above, the utility model can, in case of gas leakage, replace manual labor with a machine to perform the closing operation on the gas valve of the gas cylinder 400. This not only saves labor costs, reduces the risks of manual operation, but also improves the efficiency of handling gas leakage.

[0056] It should be noted here that if there are multiple gas cylinders 400 in the area where gas leakage occurs, there is no need to specifically check whether each gas cylinder 400 and its corresponding pipeline have gas leakage. It can be defaulted that each gas cylinder 400 and its corresponding pipeline have gas leakage, and only the screwing assembly 4 needs to be used to perform the closing operation on the gas valves of each gas cylinder 400, so as to improve the efficiency of handling gas leakage.

[0057] In some embodiments, as Figure 1 、 Figure 2 and Figure 4 shown, the clamping assembly 2 includes: a first telescopic driving member 21 and a first jaw 22;

[0058] One end of the first telescopic driving member 21 is connected to the mobile carrier 1, and the other end is connected to the first jaw 22; the first jaw 22 is used to clamp on the peripheral wall of the gas cylinder 400.

[0059] Specifically, the first telescopic driving member 21 can adopt a hydraulic cylinder or a pneumatic cylinder. The first telescopic driving member 21 drives the first jaw 22 to move to ensure that the first jaw 22 reaches a position where it can clamp the gas cylinder 400.

[0060] In some examples, the first telescopic driving member 21 can adopt a double-rod pneumatic cylinder.

[0061] In some examples, the first telescopic driving member 21 can also adopt two hydraulic cylinders arranged side by side. These two hydraulic cylinders perform telescopic actions synchronously under the drive of the hydraulic oil circuit, so as to realize the driving of the first jaw 22 to move by the two hydraulic cylinders.

[0062] In some examples, the first telescopic driving member 21 drives the first jaw 22 to approach or move away from the gas cylinder 400 in the horizontal direction. The first jaw 22 has a clamping portion adapted to the gas cylinder 400, so as to clamp the vertically distributed gas cylinder 400 based on the clamping portion.

[0063] Among them, the first jaw 22 can be a pneumatic jaw or an electric jaw.

[0064] In some embodiments, as Figure 4 shown, the first jaw 22 includes a first arcuate jaw body and a second arcuate jaw body;

[0065] The first arcuate jaw body and the second arcuate jaw body are oppositely arranged to clamp the peripheral wall of the gas cylinder 400; at least one of the first arcuate jaw body and the second arcuate jaw body is provided with a flexible pad on one side facing the gas cylinder 400.

[0066] Specifically, the first jaw 22 has a first state and a second state. When the first jaw 22 is in the first state, the first arcuate jaw body and the second arcuate jaw body approach each other, and a circular clamping opening adapted to the peripheral wall of the gas cylinder 400 is formed between the first arcuate jaw body and the second arcuate jaw body to ensure that the first arcuate jaw body and the second arcuate jaw body can clamp the peripheral wall of the gas cylinder 400; when the first jaw 22 is in the second state, the first arcuate jaw body and the second arcuate jaw body move away from each other, and the separation of the first jaw 22 from the gas cylinder 400 can be realized.

[0067] Furthermore, a flexible pad can be provided on the side surface of the first arcuate jaw body facing the gas cylinder 400 and on the side surface of the second arcuate jaw body facing the gas cylinder 400. This design can ensure that when the first jaw 22 clamps the peripheral wall of the gas cylinder 400, the first jaw 22 does not come into rigid contact with the gas cylinder 400. It can not only effectively avoid clamping damage to the gas cylinder 400 caused by the first jaw 22, but also prevent the gas cylinder 400 from rotating relative to the first jaw 22 during the process of the screwing assembly 4 closing the gas valve on the gas cylinder 400.

[0068] Among them, the flexible pad can be a rubber pad, a sponge pad or a cotton cloth pad.

[0069] In some embodiments, as Figure 2 , Figure 5 and Figure 6 shown, the robotic arm 3 includes a lifting adjustment frame 31, a transverse movement adjustment frame 32 and a second telescopic driving member 33;

[0070] The lifting adjustment frame 31 is arranged on the mobile carrier 1 and is connected to the transverse movement adjustment frame 32 to drive the transverse movement adjustment frame 32 to perform lifting movement; the transverse movement adjustment frame 32 is connected to the second telescopic driving member 33 to drive the second telescopic driving member 33 to perform horizontal movement; the second telescopic driving member 33 is connected to the screwing assembly 4 to drive the screwing assembly 4 to approach or move away from the gas valve.

[0071] Specifically, the lifting adjustment frame 31 can be arranged to extend in the vertical direction, the transverse movement adjustment frame 32 can be arranged to extend in the horizontal direction, and the second telescopic driving member 33 can be arranged to extend in the vertical direction; among them, the second telescopic driving member 33 can be a cylinder or an electric push rod.

[0072] To ensure the adjustment accuracy, at least one of the lifting adjustment frame 31 and the transverse movement adjustment frame 32 is a lead screw drive mechanism. For example, both the lifting adjustment frame 31 and the transverse movement adjustment frame 32 adopt lead screw drive mechanisms.

[0073] As Figure 5 As shown, the lifting adjustment frame 31 includes a vertical support, a first brake-equipped stepper motor, a first ball screw, a first screw nut, two vertical guide rods, and first sliders slidably disposed on each of the vertical guide rods; the first brake-equipped stepper motor is mounted on the vertical support, the first ball screw extends in the vertical direction and is rotatably disposed on the vertical support; the two vertical guide rods are oppositely disposed on both sides of the first ball screw, and each vertical guide rod extends in the vertical direction;

[0074] Wherein, the output end of the first brake-equipped stepper motor is connected to the first ball screw to drive the first ball screw to rotate; the first screw nut is sleeved outside the first ball screw and is threadedly connected to the first ball screw, the first sliders on the two vertical guide rods are arranged side by side and are both connected to the first screw nut; the first screw nut and the two first sliders are both connected to the transverse movement adjustment frame 32.

[0075] In this way, when the first brake-equipped stepper motor starts to operate, according to the sliding fit between the first slider and the vertical guide rod, the first screw nut moves vertically relative to the first ball screw under the limitation of the two first sliders, thereby driving the transverse movement adjustment frame 32 to perform lifting movement in the vertical direction.

[0076] It should be noted here that by providing two first sliders connected to the first screw nut, a relatively large supporting capacity can be provided for the transverse movement adjustment frame 32 based on the two first sliders, ensuring the stability of the lifting of the transverse movement adjustment frame 32.

[0077] As Figure 6 As shown, the transverse movement adjustment frame 32 includes a horizontal support, a second brake-equipped stepper motor, a second ball screw, and a second screw nut; the second brake-equipped stepper motor is mounted on the horizontal support, the second ball screw is rotatably disposed on the horizontal support in the horizontal direction; the output end of the second brake-equipped stepper motor is connected to the second ball screw to drive the second ball screw to rotate;

[0078] Wherein, the horizontal support has a chute extending in the horizontal direction, the second screw nut is sleeved outside the second ball screw and is threadedly connected to the second ball screw, the second screw nut is movably disposed in the chute along the extending direction of the chute and is connected to the second telescopic driving member 33;

[0079] Thus, when the second belt - brake stepping motor starts to run, according to the sliding fit between the second lead - screw nut and the chute, the first lead - screw nut moves horizontally relative to the second ball screw under the guidance of the chute, thereby driving the second telescopic driving member 33 to move horizontally.

[0080] In some examples, to ensure the reliability of the installation of the lateral translation adjusting frame 32, the lateral translation adjusting frame 32 further includes an auxiliary bracket, and the auxiliary bracket is arranged between the lateral bracket and the vertical bracket.

[0081] In some examples, to ensure the smooth horizontal translation of the second telescopic driving member 33 relative to the lateral bracket, the lateral bracket is also provided with a strip - shaped hole, the strip - shaped hole extends along the horizontal direction and is communicated with the chute; the second telescopic driving member 33 is arranged through the strip - shaped hole and is connected with the second lead - screw nut.

[0082] Among them, the second telescopic driving member 33 can be configured to extend along the vertical direction, the upper end of the second telescopic driving member 33 is connected with the second lead - screw nut, and the lower end of the second telescopic driving member 33 is connected with the screwing assembly 4.

[0083] In some embodiments, as Figure 1 and Figure 2 shown, the screwing assembly 4 includes a rotary driving member 41 and a second jaw 42; the rotary driving member 41 is connected with the second telescopic driving member 33, and the second jaw 42 is connected with the rotary driving member 41;

[0084] The rotary driving member 41 is used to drive the second jaw 42 to rotate, and the second jaw 42 is used to clamp the valve stem of the air valve.

[0085] Specifically, the rotary driving member 41 can be a belt - brake stepping motor, the rotary driving member 41 is arranged vertically, the upper end of the rotary driving member 41 is connected with the second telescopic driving member 33, and the lower end of the rotary driving member 41 serves as a rotary output end and is connected with the second jaw 42;

[0086] Among them, the second jaw 42 can be an electric jaw or a pneumatic jaw.

[0087] In some embodiments, as Figure 2 shown, the screwing assembly 4 further includes a magnetic coupling 43; the rotary driving member 41 is connected with the second jaw 42 through the magnetic coupling 43.

[0088] It can be understood that the output end of the rotary driving member 41 is connected with one end of the magnetic coupling 43, and the other end of the magnetic coupling 43 is connected with the second jaw 42; the magnetic coupling 43 is used to provide torque overload protection for the rotary driving member 41.

[0089] In practical applications, the magnetic coupling 43 can be configured to include a coupling body and a detecting member. The rotary driving member 41 is connected to the second jaw 42 through the coupling body. The detecting member is disposed on the coupling body. The detecting member can be a strain gauge or a magnetic sensitive element, and is used to detect the torque value on the coupling body. Among them, the detecting member is electrically connected to the control module, and the control module is electrically connected to the rotary driving member 41. The control module can control the rotation angle of the rotary driving member 41 according to the information fed back by the detecting member, thereby facilitating the accurate control of the second jaw 42 to perform a closing operation on the air valve.

[0090] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 shown, the mobile carrier 1 includes a vehicle body, a control module, and a traveling mechanism. The control module and the traveling mechanism are respectively disposed on the vehicle body. The gas leakage prevention device is configured with a gas detector 100. The gas detector 100 is connected to the control module, and the control module is connected to the traveling mechanism.

[0091] The gas detector 100 is used to detect the gas concentration of a special gas in the air. The special gas corresponds to the type of gas stored in the gas cylinder 400.

[0092] It can be understood that the gas stored in the gas cylinder 400 can be hydrogen, oxygen, nitrogen, argon, helium, silane gas, sulfur hexafluoride gas, etc. According to the types of these special gases, the type of the gas detector 100 is set to detect the concentration of the corresponding type of special gas. For example, the gas detector 100 can be an oxygen concentration sensor, a nitrogen concentration sensor, a helium concentration sensor, a silane concentration sensor, etc. Among them, the gas detector 100 can be disposed on the lifting adjustment frame 31 of the robotic arm 3.

[0093] When the gas detector 100 detects that the gas concentration of the special gas in the air is greater than the set value, the control module controls the moving position of the traveling mechanism according to the information fed back by the gas detector 100 until the mobile carrier 1 reaches the area where the leaking gas cylinder 400 is located.

[0094] In some embodiments, such as Figure 1 and Figure 2 shown, the gas leakage prevention device is further configured with a camera module 200. The camera module 200 is used to collect image information of the area where the gas cylinder 400 is located. The camera module 200 is connected to the control module, and the control module is respectively connected to the robotic arm 3, the screwing assembly 4, and the clamping assembly 2.

[0095] It is understandable that after the mobile carrier 1 arrives at the area where the leaking gas cylinder 400 is located, the camera module 200 collects the image information of the area where the gas cylinder 400 is located; the control module can adopt image processing algorithms well-known in the art, such as performing gray-scale processing, segmentation, cropping, etc. on the images captured by the camera module 200, to determine the position information of the gas cylinder 400 according to the image information, and respectively control the working states of the robotic arm 3, the screwing component 4 and the clamping component 2 according to the position information, so as to complete the closing operation of the gas valve on the gas cylinder 400.

[0096] In practical applications, since pressure gauges are usually provided on each gas cylinder 400, the camera module 200 can also capture the image information of the dial of the pressure gauge. The control module directly determines whether the corresponding gas cylinder 400 has a gas leak according to the image information of the dial, so as to control the working states of the robotic arm 3, the screwing component 4 and the clamping component 2, and realize the closing operation of the gas valve on the gas cylinder 400 with a gas leak.

[0097] Furthermore, as Figure 2 and Figure 5 shown, the camera module 200 can be arranged on the lifting and adjusting frame 31 of the robotic arm 3. In order to ensure that the camera module 200 captures clear images, an electric pan-tilt 300 is arranged on the lifting and adjusting frame 31, and the camera module 200 is installed on the electric pan-tilt 300. The electric pan-tilt 300 is used to perform anti-shake control on the camera module 200 to prevent the camera module 200 from being unable to collect images normally during the movement of the mobile carrier 1.

[0098] In some embodiments, the gas leak prevention device is further configured with a wireless communication module, and the wireless communication module is electrically connected to the control module and is configured to be wirelessly communicatively connected to a terminal device.

[0099] It is understandable that the wireless communication module can be a Bluetooth module, a WiFi module, a 4G module, a 5G module, etc.; the terminal device can be a smart phone, a tablet computer, etc.

[0100] In practical applications, since the wireless communication module can also send the image information collected by the camera module 200 to the terminal device, when the gas cylinder 400 and its corresponding pipeline have a gas leak, the staff can send a control instruction to the control module through the terminal device according to the image information received by the terminal device, so as to control the movement of the traveling mechanism until the mobile carrier 1 supports the clamping component 2 and the robotic arm 3 and moves to one side of the gas cylinder 400; then, an operation instruction is sent through the terminal device to control the working states of the robotic arm 3, the screwing component 4 and the clamping component 2, and realize the closing operation of the gas valve on the gas cylinder 400 with a gas leak.

[0101] In some embodiments, asFigure 3 As shown, the gas leakage prevention device further includes: a gas dilution assembly 5; the gas dilution assembly 5 includes an inert gas cylinder 51, a first control valve 52, and a gas spray head 53;

[0102] The inert gas cylinder 51 is communicated with the gas spray head 53 through the first control valve 52, and the gas spray head 53 is arranged on one side of the screwing assembly 4.

[0103] It can be understood that a storage bracket is arranged on the vehicle body of the mobile carrier 1, and both the inert gas cylinder 51 and the first control valve 52 are installed on the storage bracket. The first control valve 52 can be an electromagnetic valve and is configured to be electrically connected to the control module.

[0104] When gas leakage occurs in the gas cylinder 400 and its corresponding pipeline, the first control valve 52 can be manually controlled by the staff to open, or automatically controlled by the control module to open. The inert gas stored in the inert gas cylinder 51 flows through the first control valve 52 to the gas spray head 53 and is then discharged from the gas spray head 53.

[0105] Among them, the inert gas can be nitrogen or helium. The inert gas can dilute the flammable and explosive gas leaked in the area where the gas cylinder 400 is located, and can improve the safety of the operation process and accelerate the treatment efficiency of the leaked gas during the closing process of the gas valve.

[0106] In some embodiments, as Figure 3 As shown, the gas leakage prevention device further includes: a gas dissolution assembly 6; the gas dissolution assembly 6 includes a dissolution liquid bottle 61, an atomization pump 62, and an atomization spray head 63;

[0107] The dissolution liquid bottle 61 is communicated with the atomization spray head 63 through the atomization pump 62, and the atomization spray head 63 is arranged on one side of the screwing assembly 4.

[0108] It can be understood that a storage bracket is arranged on the vehicle body of the mobile carrier 1, and the dissolution liquid bottle 61 and the atomization pump 62 can be installed on the storage bracket; the atomization pump 62 can be configured to be connected to the control module, and the start and stop of the atomization pump 62 are controlled by the control module.

[0109] When gas leakage occurs in the gas cylinder 400 and its corresponding pipeline, the atomization pump 62 can be started. The atomization pump 62 pumps out the dissolution liquid stored in the dissolution liquid bottle 61 and transports it to the atomization spray head 63. The atomization spray head 63 sprays the dissolution liquid to the area where the gas cylinder 400 is located to dissolve special gases such as chlorine, nitrogen dioxide, fluorine gas, and hydrogen sulfide that are soluble in water leaked in these areas, thereby accelerating the treatment efficiency of the leaked gas.
