Description

Technical Field

[0001] This utility model relates to the field of gas filling protection technology, specifically an automatic gas filling protection device. Background Technology

[0002] Gas cylinder filling refers to the process of safely and compliantly filling gas cylinders (such as oxygen cylinders, liquefied gas cylinders, nitrogen cylinders, etc.) with gas (including compressed gas, liquefied gas, dissolved gas, etc.) through specialized equipment and processes. After the gas is compressed, liquefied or dissolved, it is put into the gas cylinder to make it a portable energy source or industrial raw material that is easy to transport, store and use, and meet the needs of industrial production, medical emergency and people's livelihood.

[0003] However, the existing gas cylinder filling process lacks protection during the filling process. During the filling process, the gas may explode or rupture due to overpressure, corrosion, fatigue, etc., resulting in high-speed flying fragments. At the same time, gas may also leak due to improper operation, all of which pose a serious threat to the safety of workers. Therefore, an automatic protection device for gas filling is proposed.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only some embodiments, not all embodiments. Based on the embodiments described, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0022] Example 1:

[0023] Please see Figure 1-3 An automatic gas filling protection device includes an equipment frame 1, an equipment frame 2 fixedly installed on the upper part of the equipment frame 1, a hydraulic rod 3 fixedly installed on the upper surface of the equipment frame 2, a lifting plate 4 fixedly installed at the lower end of the hydraulic rod 3, a gas pipe 5 installed at the lower part of the lifting plate 4, an installation plate installed on the rear side of the equipment frame 2, a lead screw 7 rotatably installed on the inner wall of the installation plate, a moving block 9 threadedly installed on the outer side of the lead screw 7, a motor 8 fixedly installed on the upper part of the installation plate, a connecting block 10 fixedly installed on the outer side of the moving block 9, a protective cover 11 fixedly installed on the outer side of the connecting block 10, and a bottom clamping plate 12 fixedly installed in the middle inner layer of the equipment frame 1.

[0024] Specifically, the protective cover 11 is made of transparent explosion-proof material to ensure that the operation process is visible and safe. After the protective cover 11 moves downward, it can fit tightly with the bottom plate 12 for protection. The hydraulic rod 3 can drive the lifting plate 4 to move. An air distribution device is installed inside the lifting plate 4. The air distribution device is connected to multiple air pipes 5 through an air distribution valve.

[0025] Preferably, the output end of the motor 8 is fixedly connected to the upper end of the lead screw 7, a sliding groove is provided on the rear side of the equipment frame 2, the outer side of the connecting block 10 is slidably connected to the inner wall of the sliding groove, and the outer side of the protective cover 11 is slidably connected to the inner wall of the equipment frame 2.

[0026] Specifically, the motor 8 can drive the lead screw 7 to rotate, the moving block 9 moves up and down along the lead screw 7, the moving block 9 can drive the connecting block 10 and the protective cover 11 to slide synchronously, and the connecting block 10 moves along the slide groove.

[0027] Preferably, an inflation valve is installed at the lower part of the air tube 5, and an anti-tangle tube 6 is provided on the outside of the air tube 5.

[0028] Specifically, the anti-tangling tube 6 ensures that the air tube 5 does not become tangled during movement.

[0029] Preferably, a gas detector 17 is installed inside the protective cover 11, and a controller 18 is fixedly installed on the outside of the equipment frame 2. The gas detector 17 is electrically connected to the controller 18, and a buzzer alarm is installed inside the controller 18.

[0030] Specifically, the gas detector 17 can detect various industrial gases and display the data in real time through the controller 18. When an anomaly is detected, the buzzer alarm in the controller 18 will immediately activate, sounding an alarm to remind operators to handle the situation promptly and ensure safety. The controller 18 can also remotely transmit data for easy monitoring and management.

[0031] Working principle: During operation, the hydraulic rod 3 is controlled to move the lifting plate 4 downwards. The lifting plate 4 moves the air pipe 5 downwards. Then, the operator connects the filling valve under the air pipe 5 to the valve on the gas cylinder 16. When filling is started, the motor 8 drives the lead screw 7 to rotate. The rotation of the lead screw 7 causes the moving block 9 to descend. The moving block 9 causes the connecting block 10 to move downwards. The connecting block 10 causes the protective cover 11 to descend as well. The bottom of the protective cover 11 moves to the sealing plate, so that the protective cover 11 seals the inside of the gas cylinder 16 in the equipment frame, thereby preventing accidents caused by the gas cylinder 16. In the event of an explosion of the gas cylinder 16, it can effectively block or buffer the impact of fragments and limit the scope of the hazard. At the same time, the protective cover 11 can slow down the diffusion speed of leaked gas, giving the operator time to evacuate or handle the emergency.

[0032] Example 2:

[0033] Please see Figure 1-3 The equipment rack 1 is equipped with a transport rack 13 inside, and a rubber isolation belt 14 is installed inside the transport rack 13. A positioning hole 15 is opened at the bottom of the transport rack 13, and a rubber interlayer is provided on the inner wall of the positioning hole 15.

[0034] Specifically, the rubber clamp on the inner wall of the positioning hole 15 can tightly wrap around the bottom of the gas cylinder 16, which can fix and buffer the gas cylinder 16.

[0035] Preferably, a gas cylinder 16 is installed inside the positioning hole 15, and the areas where the rubber isolation strips 14 intersect are correspondingly set with respect to the positioning hole 15.

[0036] Specifically, the rubber isolation strips 14 form a mesh structure at the intersections, which enhances the fixing effect on the gas cylinder 16. The areas where the rubber isolation strips 14 intersect and correspond to the positioning holes 15 also serve a positioning function, allowing the gas cylinder 16 to be quickly installed into the positioning holes 15.

[0037] Working principle: Gas cylinders 16 are placed sequentially into the transport frame 13. The bottom of the gas cylinder 16 is installed into the positioning hole 15, and the bottom of the gas cylinder 16 is tightly fixed by the rubber interlayer to ensure stability during transportation. At the same time, the mesh structure of the rubber isolation strip 14 further enhances the stability of the gas cylinder 16, preventing it from shifting during transportation and avoiding collisions between gas cylinders 16. In addition, both the rubber isolation strip 14 and the rubber interlayer are elastic, which can provide adaptive fixation for different sizes of gas cylinders 16, thereby effectively protecting the gas cylinders 16 and preventing damage caused by bumps or collisions during transportation.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
