Technical Field

[0001] The utility model relates to the technical field of gas cylinders, and particularly relates to a gas cylinder pressure detector. Background Art

[0002] At present, a gas cylinder pressure detector is an instrument used to monitor and ensure that the internal pressure of a compressed gas cylinder is within a safe range. Compressed gases are usually stored in high-pressure gas cylinders, which can contain different types of gases such as oxygen, nitrogen, carbon dioxide, helium, etc. Since these gases are stored under high pressure, it is necessary to regularly check their pressure to ensure safety.

[0003] When the existing gas cylinder pressure detector detects the air pressure of a gas cylinder, it mainly uses a sensor for detection or cooperates with a water tank. The water tank is filled with clean water. During the process of detecting the air pressure of the gas cylinder, the gas cylinder is placed in the water tank. By observing whether there are bubbles generated, the airtightness and pressure-bearing capacity of the gas cylinder can be detected. However, there are still deficiencies in its actual use. After the gas cylinder is taken out of the water tank and transferred to the next work station, the water stains on the outer surface of the gas cylinder will drip on the way and at other work stations, resulting in a wet working site and causing the surfaces of other equipment to be wet, which is prone to rust and is not conducive to protecting the equipment.

Detailed implementation manners

[0027] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0028] The present utility model provides a cylinder pressure detector as shown in Figure 1 - Figure 9 , which includes a water tank 7. A drain pipe 11 is provided on one side of the bottom of the water tank 7. A liftable support plate 71 is provided above the water tank 7. A detection mechanism is provided above the support plate 71. The detection mechanism includes a pressure detection device 9 provided on one side of the water tank 7. The air outlet of the pressure detection device 9 is connected to an inflation assembly 14. The inflation assembly 14 includes a hose 10. One end of the hose 10 is connected to a conduit 144. One end of the conduit 144 is connected to a pipeline 141. An exhaust pipe 142 is provided at the bottom of the pipeline 141. A valve joint 143 is provided at the bottom of the exhaust pipe 142;

[0029] Exhaust devices are provided on both sides of the support plate 71. The exhaust devices include a first exhaust plate 6. One end of the first exhaust plate 6 is connected to a connecting pipe 62. One end of the connecting pipe 62 extends and is connected to a second exhaust plate 61. A plurality of high-pressure air pumps 63 are provided on one side of the second exhaust plate 61; A plurality of holes are provided on the surfaces of the first exhaust plate 6 and the second exhaust plate 61 to facilitate air discharge;

[0030] In this embodiment, specifically, the working principle of the pressure detection device 9 is prior art and will not be elaborated here. The pressure detection device 9 inflates through a pump body. The gas passes through the hose 10, then through the conduit 144, then through the pipe 141, then through the exhaust pipe 142 and the valve connector 143, and finally enters the cylinder body 13. The cylinder body 13 is filled with pressure. If there are damages on the outside and outside of the cylinder, the gas will overflow from the damaged place, and bubbles will be generated in the water in the water tank. At the same time, the pressure detection device 9 continuously inputs gas into the cylinder to keep the inside of the cylinder in a high-pressure state. At the same time, the pressure gauge on the pressure detection device 9 also shows the pressure value. By comparing the production standard pressure value of the cylinder with the measured pressure value, the user can know whether the pressure of the cylinder meets the requirements;

[0031] Specifically, the connecting pipe 62 is of a soft structure. Pushing or pulling the first exhaust plate 6 can cause the first exhaust plate 6 to act, so that the first exhaust plate 6 can be flipped, thereby exposing the top of the support plate 71, facilitating the placement of the cylinder on the top of the support plate 71. After placing the cylinder, push the first exhaust plate 6 back to its original position so that the first exhaust plate 6 blocks in front of the cylinder;

[0032] Before the air pressure detection, the inflation assembly 14 moves downward, and the valve connector 143 continuously moves downward and connects with the air inlet on the top of the cylinder body 13, thereby inputting gas into the inside of the cylinder body 13;

[0033] After the air pressure detection is completed, the cylinder moves above the water tank 7, and the high-pressure air pump 63 is started. The high-pressure air pump 63 quickly fills the second exhaust plate 61 with gas. The gas enters the first exhaust plate 6 after passing through the connecting pipe 62. The air and water inside the first exhaust plate 6 and the second exhaust plate 61 are quickly pressed out, and the high-speed wind blows towards the surface of the cylinder, thereby drying the water on the surface of the cylinder.

[0034] As Figure 1 - Figure 5 As shown, specifically, one end of the support plate 71 is fixed to the second exhaust plate 61. A lifting device is further provided on one side of the second exhaust plate 61. The lifting device includes a linear motor 12. One side of the slider of the linear motor 12 is connected with a connecting block 121. The connecting block 121 is fixedly connected with the connecting pipe 62 by bolts;

[0035] In this embodiment, specifically, while the lifting slider of the linear motor 12 drives the connecting pipe 62 to move, it also drives the second exhaust plate 61 to move, thereby driving the second exhaust plate 61 to lift through the linear motor 12, causing the second exhaust plate 61 to drive the support plate 71 to act, and the structure on the top of the support plate 71 also acts, so that the cylinder body 13 placed on the top of the support plate 71 can be placed into the water tank 7.

[0036] AsFigure 1 and Figure 6 As shown in Figure 6 , a positioning seat 4 is provided above the detection mechanism, an installation plate 2 is provided above the positioning seat 4, one end of the installation plate 2 is connected to a support frame 1, a cylinder 3 is fixed on the top of the installation plate 2, and the telescopic end of the cylinder 3 penetrates through the installation plate 2 and extends downward to be connected to the positioning seat 4;

[0037] In this embodiment, the telescopic end of the cylinder 3 drives the positioning seat 4 to move up and down, so that the inflation assembly at the bottom of the positioning seat 4 can move up and down. At the same time, since the hose 10 is a soft structure, the hose 10 can be deformed when the inflation assembly moves up and down, which is beneficial to the free movement of the inflation assembly up and down without being blocked by other structures.

[0038] As Figure 6 shown in Figure 6 , a waterproof plate 5 is further provided below the positioning seat 4, a through hole 16 is opened at the top of the waterproof plate 5, and the exhaust pipe 142 extends downward and penetrates through the through hole 16; it should be noted that the waterproof plate 5 separates the cylinder body 13 and the support plate 71, preventing the water stains from splashing on the pipeline 141 and the conduit 144 when the cylinder body 13 moves upward after the air pressure detection is completed, thereby appropriately protecting the pipeline 141 and the conduit 144;

[0039] It should be noted that when the cylinder 3 pushes the positioning seat 4 downward, it also pushes the inflation assembly 14 downward. The waterproof plate 5 presses the top of the first exhaust plate 6, and the bottom of the first exhaust plate 6 is located on the top of the support plate 71. At this time, the first exhaust plate 6 is pressed tightly.

[0040] As Figure 1 and Figure 8 shown in Figure 8 , a positioning ring 15 is further provided on the top of the support plate 71, and a cylinder body 13 is placed on one side of the positioning ring 15 on the top of the support plate 71; specifically, when the cylinder body 13 is placed on the top of the support plate 71, the first exhaust plate 6 is opened. Under the blocking action of the positioning ring 15, the bottom of the cylinder body 13 fits against the inner wall of the positioning ring 15, so that the cylinder body 13 cannot move left and right.

[0041] As Figure 8 shown in Figure 8 , guide seats 8 are provided at the four corners inside the water tank 7, and the support plate 71 can move up and down between the four guide seats 8; specifically, a right-angled groove is opened inside the guide seat 8, and the right-angled groove fits against the four corners of the support plate 71, so that the support plate 71 will not be displaced during the up and down movement.

[0042] Only some exemplary embodiments of the present utility model are described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
