[0033] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0034] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0035] Example 1

[0036] Reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a gas cylinder protection device, which includes a placement rack 2, at least two support plates 21 are provided on the placement rack 2, and a placement groove 24 is opened on the support plate 21;

[0037] The placement rack 2 provides placement conditions for the gas cylinders, and through the setting of the support plate 21 and the placement groove 24, the support points of the placement rack 2 for the gas cylinders can be increased, ensuring that the placement rack 2 can protect the gas cylinders. At the same time, the cooperation between the placement groove 24 and the rubber ring 1 can also further protect the gas cylinders to avoid damage to the gas cylinders.

[0038] The placement groove 24 is provided to make the support plate 21 open, so as to facilitate the installation and placement of the gas cylinder.

[0039] The fastener 3 has two ends connected to the support plate 21 so that the fastener 3 and the placement groove 24 form a closed loop.

[0040] By providing the fastener 3 , the gas cylinder can be fixed after being placed into the placement groove 24 , ensuring that the gas cylinder is stably placed in the placement groove 24 .

[0041] When in use, it is placed on the bottom plate of the placement rack 2, and then the position of the rubber ring 1 on the outer ring of the gas cylinder is adjusted by the height of the support plate 21, so that the rubber ring 1 can be placed in the middle position of the placement groove 24 to ensure that the friction between the gas cylinder and the placement groove 24 is increased, and then the open side of the placement groove 24 is surrounded by the fastener 3 to form a closed loop with the placement groove 24, so that the gas cylinder can be fixed in the placement groove 24 to ensure the stable installation of the gas cylinder.

[0042] Example 2

[0043] Reference Figures 2 to 6 , which is the second embodiment of the present invention, is different from the first embodiment in that: it also includes a pressure plate 23 provided above the bottom plate of the placement rack 2, and a pressure transmitter 231 is detachably installed in the bottom plate of the placement rack 2, the bottom of the pressure plate 23 is in contact with the pressure transmitter 231, and the pressure transmitter 231 is electrically connected to the control unit.

[0044] The pressure plate 23 is arranged above the bottom plate of the placement rack 2, and there is a sliding relationship between the pressure plate 23 and the vertical rod of the placement rack 2. The pressure transmitter 231 set in the bottom plate of the placement rack 2 can receive the pressure given by the pressure plate 23. When the gas cylinder is placed on the pressure plate 23, the pressure transmitter 231 will feel the pressure from the gas cylinder. While sensing the pressure, the pressure transmitter 231 will transmit a signal to the control unit to confirm that a gas cylinder has been placed on the pressure plate 23.

[0045] A rubber ring 1 is also provided at the position where the bottom of the gas cylinder contacts the pressure plate 23, which can prevent the bottom of the gas cylinder from rubbing against the pressure plate 23 more severely, and can also provide an anti-slip effect, making it more firmly fixed.

[0046] Specifically, a fixing member 31 is provided at one end of the fastener 3, and the fixing member 31 is fixed to one end of the opening side of the support plate 21. A second connecting member 32 is provided at a position of the fastener 3 different from one end of the fixing member 31. The second connecting member 32 is detachably connected to the other end of the opening side of the support plate 21, and a first contact is provided on the second connecting member 32.

[0047] Furthermore, a first connector 25 is provided at one end of the support plate 21 connected to the second connector 32 . The first connector 25 cooperates with the second connector 32 , and a second contact is provided in the first connector 25 . The first contact and the second contact are electrically connected.

[0048] Furthermore, both the first contact and the second contact are electrically connected to the control unit.

[0049] The fastener 3 is formed by connecting a plurality of connection joints and has shape changeability. The setting for the connection joints not only includes the attachment Figure 5 The ring shape in the figure may also be a column shape, etc., and is not specifically limited here.

[0050] The fixing member 31 is fixedly connected to one end of the open side of the support plate 21, and one side of the second connecting member 32 is detachably matched with the first connecting member 25, which can facilitate the installation and fixation of the gas cylinder. A first contact is provided on the fixing member 31, and a second contact is provided on the first connecting member 25. When the two contacts are in contact, a signal can be given to the control unit.

[0051] The docking mode between the fixing member 31 and the second connecting member 32 is not limited to the shape shown in the drawings, and may also be a detachable column, etc., which is not specifically limited here.

[0052] After the pressure transmitter 231 detects the pressure, it transmits the signal to the control unit. At this time, the first contact on the second connecting member 32 is not in contact with the second contact on the first connecting member 25. The control unit will issue an alarm to remind the staff. After receiving the reminder, the staff will connect the second connecting member 32 with the first connecting member 25 so that the fastener 3 and the placement groove 24 form a closed loop, thereby confining the gas cylinder therein. After the first contact contacts the second contact, a signal will be fed back to the control unit. After receiving the connection signal, the control unit will eliminate the alarm. The power supply of the pressure transmitter 231 can be provided by an external wire, or a mobile power supply can be placed on the placement rack 2.

[0053] Furthermore, after the alarm is eliminated, the pressure sensing range of the pressure transmitter 231 can also be increased. When the pressure transmitter 231 detects that the weight of the gas cylinder and the material contained in the gas cylinder is too low, it means that the material in the gas cylinder is less and needs to be replaced. At this time, the pressure transmitter 231 will also transmit a signal to the control unit, and the control unit will notify the staff to replace the corresponding gas cylinder.

[0054] As for how to judge the weight, the weight of the gas cylinder itself is certain. The control unit can set the weight of the gas cylinder plus the weight of the minimum material required for the operation. The mass of the material can be set according to the actual operation requirements. No specific limitation is made here. When the pressure changer 231 detects that the weight is less than this, it proves that the remaining material in the gas cylinder is insufficient for the next operation, so it is necessary to notify the staff to replace the corresponding gas cylinder.

[0055] Specifically, it also includes a rubber ring 1, which is sleeved on the outside of the gas cylinder and placed in the placement groove 24.

[0056] By setting the rubber ring 1, when the gas cylinder is placed in the placement groove 24, the gas cylinder bracket can be prevented from contacting the placement groove 24, and the friction between the gas cylinder and the placement groove 24 is increased during use or storage, making the device more stable and less likely to shake, while also being able to protect the gas cylinder.

[0057] Specifically, a handle 22 is provided on the top of the support plate 21 located at the top of the placement rack 2. The handle 22 facilitates the staff to cooperate with the moving component 4 to push the device to move, making it more convenient to use.

[0058] Specifically, it also includes a moving component 4, which includes two symmetrically arranged support frames 41. A universal wheel 42 is set at one end of the support frame 41, and the lowest point of the universal wheel 42 is on the same horizontal line as the lowest point of the protruding end of the support frame 41.

[0059] Furthermore, the two support frames 41 are fixedly connected via at least one connecting plate 43 , and the moving assembly 4 is installed at the bottom of the placement frame 2 .

[0060] By setting up the two support frames 41, the contact range between the bottom of the placement rack 2 and the ground can be expanded, making the placement rack 2 more stable. At the same time, by setting up the universal wheels 42 and the handle 22, it can help the staff to move the device.

[0061] Attachment Figure 2 It indicates that the support frame 41 is extended only in the axial direction of the opening of the support plate 21. The device is not limited to this direction, but can also be extended in the direction perpendicular to the opening side of the support plate 21, further increasing the range and ensuring that it can be extended without affecting its movement through the universal wheel 42.

[0062] The universal wheel 42 is L-shaped, and the universal wheel 42 is installed at the end without the protrusion. The lowest point of the protrusion of the universal wheel 42 is on the same horizontal line as the lowest point of the universal wheel 42 to ensure that the device can be in a vertical state when it is not moved.

[0063] Specifically, the distance measuring assembly 5 is also included. The distance measuring assembly 5 includes a mounting member 51 fixed to the top of the support plate 21 and a rangefinder 52 mounted on the side wall of the mounting member 51. At least one rangefinder 52 is provided.

[0064] The mounting member 51 is a detachable block or the like, which facilitates installation or removal of the rangefinder 52 . The detachable mounting member may be a block, a buckle, a lock, etc., which is not specifically limited here.

[0065] The setting of the distance meter 52 can ensure that the placement of multiple placement racks 2 is at a safe distance, thereby ensuring the safety of the operation.

[0066] When in use, first place the gas cylinder on the pressure plate 23, and adjust the rubber ring 1 to the position corresponding to the placement groove 24, then place the gas cylinder in the placement groove 24 so that its vertical direction remains parallel to the vertical rod on the placement rack 2, then adjust the position of the second connecting member 32 on the fastener 3, and then connect the second connecting member 32 to the first connecting member 25, and ensure that the connection is tight.

[0067] Example 3

[0068] Reference Figure 7 , which is the third embodiment of the present invention, is based on the first two embodiments and provides a gas cylinder protection device and placement method, which includes

[0069] Color-code gas cylinders and welding guns based on gas properties;

[0070] First, the gas stored in the gas cylinder is marked with color according to the gas properties, such as marking combustible gas cylinders as red, oxidizer gas cylinders as green, and hot work welding guns as yellow.

[0071] measuring the distances between the plurality of gas cylinders and between the plurality of gas cylinders and the welding gun by means of a distance meter 52;

[0072] The modules in the rangefinder 52 are as follows:

[0073] Main control chip: STM32 series (low-power MCU) or ESP32 (supports Wi-Fi / BLE).

[0074] Ranging module: UWB chip (such as Qorvo DW3000) or Bluetooth 5.0 module (such as HC-05).

[0075] Alarm module: 8Ω buzzer (adjustable volume) emits sound, linear motor (silent mode) provides vibration effect, and LED red light flashes for warning.

[0076] Power management: lithium battery powered (supports USB-C fast charging).

[0077] Software Design

[0078] Real-time ranging algorithm:

[0079] UWB: Distance is calculated based on time of flight (ToF).

[0080] BLE: RSSI signal strength estimation (needs to calibrate environmental interference)

[0081] According to the actual needs on site, different color rings of red, green and yellow are set for the variable distance section rangefinder 52, and measurement is performed through the UMB module inside the rangefinder 52. The UMB module can achieve centimeter-level accuracy and is suitable for a variety of environments. When the rangefinder 52 detects that the distance between the red combustible gas cylinder, the green oxidizer gas cylinder and the yellow hot work welding gun is less than the set distance, an alarm will be generated, and vibration will occur and the LED red light will flash.

[0082] Using the positioning card on the placement rack (2), determine the number of gas cylinders and welding guns to be arranged at the work site;

[0083] The positioning card can be transmitted to the control unit via 5G, making it easy for staff to view and clearly determine the number of gas cylinders arranged at the work site and the layout of the gas cylinders at the on-site hot work point. The positioning card can be installed by magnetic suction, snap fasteners, etc.

[0084] Setting safety distance parameters between multiple gas cylinders and between multiple gas cylinders and welding guns through a distance meter (52);

[0085] The safety distance between the red combustible gas cylinder and the green oxidizer gas cylinder is greater than or equal to 5 meters, and the safety distance between the red combustible gas cylinder and the yellow hot work welding gun, and the safety distance between the green oxidizer gas cylinder and the yellow hot work welding gun is set to be greater than or equal to 10 meters. When the rangefinder 52 detects that the distance is less than the set distance, it triggers an alarm and transmits it to the control unit to remind the staff to change its position.

[0086] In this step, the red combustible gas cylinder, the yellow hot work welding gun, and the green oxidizer gas cylinder can be arranged in a straight line, a triangle, etc., but a safe distance must be ensured between the three.

[0087] The triangular shape allows for more convenient interaction between the three while maintaining a safe distance.

[0088] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
