[0002] According to the requirements of the specification, during construction work, the working distance between oxygen cylinders and acetylene cylinders shall not be less than 5m; when transporting, storing, and using gas cylinders, the gas cylinders should be kept upright and anti-dumping measures should be taken. Acetylene cylinders are strictly prohibited from lying horizontally. At present, large-scale projects or construction sites with large welding volumes require a large number of oxygen cylinders and acetylene cylinders for welding operations. In order to prevent dumping, the gas cylinders are placed in cages, but there are often reasons such as insufficient understanding of the safe working distance of gas cylinders by construction workers and negligence of on-site management personnel, resulting in the working distance between oxygen cylinders and acetylene cylinders at the construction site being often less than 5m, posing a safety hazard. In the prior art, there are also improvement plans for this problem.

When the two ends of the two conductive rods 300 are respectively placed on the corresponding first contact seats 110 and second contact seats 210 on both sides, the alarm device 125 eliminates the alarm. By installing two first contact seats 110 on the first placement cage 100 and two second contact seats 210 on the second placement cage 200, when the two ends of the conductive rod 300 are placed on the first contact seats 110 and the second placement cage 200, the conductive rod 300 is supported between the first placement cage 100 and the second placement cage 200, so that the distance between the first placement cage 100 and the second placement cage 200 is controlled by the two conductive rods 300. Since the two first contact seats 110 are electrically connected to the controller 123 respectively, and the two second contact seats 210 are connected in series, when the conductive rod 300 is supported between the first placement cage 100 and the second placement cage 200, Figure 4 , providing a circuit conduction signal to the controller 123, and the controller 123 then controls the alarm device 125 to turn off, thereby eliminating the alarm.

[0036] When in use, if the conductive rod 300 is not placed between the first placement cage 100 and the second placement cage 200, the alarm device 125 will sound an alarm.

The electromagnetic lock 104 is installed in the cage 101, the lock tongue is extended, and a socket is provided on the opening and closing door 103 at a position corresponding to the electromagnetic lock 104. When the lock tongue is extended into the socket, the opening and closing door 103 is locked. When the door opening button 124 is pressed, the electromagnetic lock 104 is energized and the lock tongue is retracted.

[0040] See also Figure 3 , 4 The cage body 101 of the first placement cage 100 is also equipped with an electric door lock 122, which is electrically connected to the battery 121 and the controller 123, and is used to control the on and off of the power supply of the controller 123.

Since the use location is outdoor, the storage battery 121 can be charged by setting the solar panel 400 and the matching solar control unit 410.

[0044] The solar control unit 410 adopts the EL-MU series solar cell charge controller produced by Yi Neng Jie Electronics (Taizhou) Co., Ltd.

[0045] See also Figure 2 , 5 -7, the first contact seat 110 and the second contact seat 210 both include a protruding plate 111 and a connecting plate 112, one end of the two protruding plates 111 is connected to the cage body 101, and the lower side of the other end is connected to the connecting plate 112, an insulating plate 113 is installed on the connecting plate 112, a conductive block 115 is installed on the insulating plate 113, and two limit blocks 116 are also installed on the conductive block 115, the limit blocks 116 are made of insulating material, and a limit groove 117 is formed between the two limit blocks 116.

[0052] The working principle or action process of the utility model is as follows:

[0053] See also Figure 1 , 3 When the utility model is in use, the first placement cage 100 and the second placement cage 200 are first placed in the working area, the distance between the first placement cage 100 and the second placement cage 200 is adjusted, and then the two ends of the two conductive rods 300 are respectively placed in the limiting grooves 117 on the first contact seat 110 and the second contact seat 210 on both sides.

[0054] Afterwards, the electric door lock 122 is opened by the key, and the controller 123 is powered. If the conductive rod 300 is not installed between the two first contact seats 110 to form a loop, the controller 123 controls the alarm device 125 to sound an alarm; if a loop is formed between the two first contact seats 110, the controller 123 controls the alarm device 125 to eliminate the alarm. Thus, the distance between the first placement cage 100 and the second placement cage 200 is guaranteed.
