[0002] In order to ensure the power supply, the current air replenishment of sulfur hexafluoride equipment adopts live air replenishment operation. During the live air replenishment process, the staff needs to complete the air replenishment work based on the air replenishment experience. However, when the gas line is just connected, the sulfur hexafluoride gas in the equipment body will leak out to a certain extent, further reducing the gas pressure in the equipment body. If the staff lacks experience in live air replenishment operations, improper operation will easily cause a large amount of gas in the equipment to leak out, seriously threatening the equipment and personal safety. At present, the air replenishment operation adopts manual air replenishment, which requires repeated tedious operations such as carrying gas cylinders and disassembling and assembling gas replenishment pipelines. In addition, the gas cylinders are heavy and inconvenient to carry, which increases the difficulty of air replenishment and greatly reduces work efficiency. Summary of the invention

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1The gas replenishing device shown in the figure includes a gas tank 100, a pressure regulating valve 200, a gas filling component 300, a gas supply pipe 400 and a control component 500. The gas tank 100 is used to contain compressed gas (for example, sulfur hexafluoride); the pressure regulating valve 200 is connected to the gas tank 100 to adjust the pressure of the gas flowing out of the gas tank 100; the gas filling component 300 includes a solenoid valve 31, a one-way valve 32 and a pressure transmitter 33, the solenoid valve 31 is connected to the pressure regulating valve 200, and the one-way valve 32 is connected to the solenoid valve 31 and the one-way valve 32 respectively. 1 and the pressure transmitter 33; the air supply pipe 400 is communicated with the pressure transmitter 33; the control component 500 is electrically connected to the solenoid valve 31, the pressure transmitter 33 and the pressure regulating valve 200, and the control component 500 is used to control the solenoid valve 31, the pressure transmitter 33 and the pressure regulating valve 200; wherein, the air supply pipe 400 is used to connect the external device, the pressure transmitter 33 is used to detect the air pressure inside the external device, the one-way valve 32 is used to prevent the gas from flowing back, and the solenoid valve 31 is used to control the interruption of the gas flow.

[0031] It should be noted that the above-mentioned pressure transmitter 33, air supply pipe 400 and one-way valve 32 are connected via a three-way connector, and the pressure transmitter 33, air supply pipe 400 and one-way valve 32 are respectively connected to the three interfaces of the three-way connector, and the three interfaces of the three-way connector are all connected to each other; the gas tank 100 and the pressure regulating valve 200, the pressure regulating valve 200 and the solenoid valve 31, and the solenoid valve 31 and the one-way valve 32 are all connected and communicated through pipelines.

[0032] In actual applications, after the air supply pipe 400 is connected to the external device, part of the gas in the external device will flow into the air supply pipe 400. The pressure transmitter 33 then detects the gas pressure inside the air supply pipe 400 and transmits the detection data to the control component 500. The control component 500 determines whether the external device needs to be replenished with gas based on the data detected by the pressure transmitter 33. In the process of the gas inside the external device flowing into the air supply pipe 400, the one-way valve 32 can prevent the gas inside the external device from further backflowing to avoid gas leakage. If the external device needs to be replenished with gas, the control component 500 controls the pressure regulating valve 200 to adjust the output pressure of the gas tank 100 to an appropriate value to prepare for replenishing gas to the external device. After the pressure regulating valve 200 has adjusted the output gas pressure, the control component 500 controls the solenoid valve 31 to open. At this time, the gas inside the gas tank 100 can pass through the pressure regulating valve 200, the solenoid valve 31, the one-way valve 32, the pressure transmitter 33 in sequence, and finally flow into the external device through the air supply pipe 400. When the air pressure inside the external device reaches a predetermined value, the pressure transmitter 33 transmits the detected data to the control component 500, and the control component 500 controls the solenoid valve 31 to close, and then controls the pressure regulating valve 200 to close to complete the gas replenishment operation to the external device. Through the above process, the gas replenishment operation is fully automatic, the experience requirements for the staff are low, the operation is simple and safe, and the work efficiency of the gas replenishment operation is greatly improved.

[0033] The following will introduce the technical details of each component one by one.

[0034] In some embodiments, Figure 1 , Figure 2 As shown, the control assembly 500 includes a screen 51 and a control module 52, and the screen 51 is electrically connected to the control module 52. The control module 52 can transmit the information transmitted by the pressure transmitter 33, the pressure regulating valve 200, the solenoid valve 31 and other components to the screen 51 for display, and the operator can observe each data intuitively through the screen 51, so that the operator can understand the operating status of the equipment in real time.

[0035] Furthermore, the screen 51 is a touch screen. If the screen 51 is a touch screen, the operator can issue instructions to the control component 500 by touching the screen 51 so that the control component 500 controls various components; at the same time, if the screen 51 is a touch screen, there is no need to set up extra buttons and other operating components, making the overall appearance of the device more concise and convenient for the operator to control the gas replenishing device.

[0036] In some embodiments, Figure 1 , Figure 2 As shown, the above-mentioned air replenishing device also includes an assembly panel 600, which is a flat plate. The pressure regulating valve 200, the inflation component 300 and the control component 500 are all flatly fixed on the same side of the assembly panel 600, so that the operator can observe each component intuitively. If a fault such as leakage occurs, the operator can find it in time and intuitively so as to deal with it in time; and the pressure regulating valve 200, the inflation component 300 and the control component 500 are all flatly fixed on the same side of the assembly panel 600, which can also make the assembly process of the device simpler, and each component is easier to install and connect when replaced.

[0037] In some embodiments, Figure 1 , Figure 2 As shown, the assembly panel 600 is fixed with a plurality of fixings 01, which can be a group of mutually matching buckles, or a bolt or a bolt seat. The solenoid valve 31 and the pressure transmitter 33 are both detachably connected to the assembly panel 600 through the fixings 01. The fixing method of the fixings 01 is convenient for installing the equipment on the assembly panel 600 and for disassembling and replacing each component. In addition to the above effects, the fixing method of the fixings 01 can also avoid damage to the assembly panel 600 during the disassembly process.

[0038] In some embodiments, Figure 1 , Figure 2As shown, the above-mentioned air replenishing device includes a plurality of air-filling components 300, the plurality of air-filling components 300 are arranged in parallel, the plurality of air-filling components 300 are respectively connected to the pressure regulating valve 200 through pipelines, and the plurality of air-filling components 300 are respectively connected to the air supply pipe 400. The plurality of air-filling components 300 are connected in parallel through a multi-channel connector (a component that can convert one pipeline into multiple pipelines, usually with one air inlet and multiple air outlets, each of which is connected to the air inlet), and the airflow out of the pressure regulating valve 200 is split through the multi-channel connector to form a plurality of separate airflow branches, and the plurality of air-filling components 300 are connected to the plurality of separate airflow branches one by one.

[0039] Through the above design, the air supply device can supply air to multiple devices at the same time, thereby improving the working efficiency of the air supply device.

[0040] In some embodiments, Figure 3 As shown, the above-mentioned air replenishing device also includes a protective component 700, and an assembly cavity is opened inside the protective component 700. The gas cylinder 100, the pressure regulating valve 200, the gas charging component 300 and the air supply pipe 400 are all arranged inside the assembly cavity. The protective component 700 can protect and store the gas cylinder 100, the pressure regulating valve 200, the gas charging component 300 and the air supply pipe 400. At the same time, after the gas cylinder 100, the pressure regulating valve 200, the gas charging component 300 and the air supply pipe 400 are stored inside the protective component 700, it is also convenient for the staff to carry the air replenishing device.

[0041] In some embodiments, Figure 3 As shown, the protective assembly 700 includes a housing 71 and wheels 72, and the wheels 72 are arranged on the bottom surface of the housing 71. The arrangement of the wheels 72 can facilitate the movement of the air replenishing device on a plane, and is also conducive to the movement and transportation of the staff.

[0042] In some embodiments, Figure 3 , Figure 4 As shown, the inner wall of the assembly cavity is provided with a hanging part 02, and the air supply pipe 400 can be selectively hung on the hanging part 02. In actual application, the air supply pipe 400 is often relatively long, which is very inconvenient to store, and the air supply device is often provided with multiple air supply pipes 400; after the air supply operation structure, the operator can wind the air supply pipe 400 around the hanging part 02. Such a design can facilitate the storage of the air supply pipe 400 and avoid the air supply pipe 400 from being entangled and knotted so that the staff can use it next time.

[0043] See also Figure 1 , Figure 2 , Figure 5For understanding, the present application provides an automatic air replenishment method, which adopts the above-mentioned air replenishment device, and the automatic air replenishment method includes:

[0044] The pressure transmitter 33 and the air supply pipe 400 are in a connected state, and are connected to an external device through the air supply pipe 400. The pressure transmitter 33 detects the air pressure data inside the external device and transmits it to the control component 500. The control component 500 determines whether the external device needs to be supplemented with air according to the air pressure inside the external device.

[0045] If the internal air pressure of the external device is lower than the predetermined air pressure, the control component 500 controls the solenoid valve 31 to open and controls the pressure regulating valve 200 to output gas to replenish the external device. When the internal air pressure of the external device reaches the predetermined air pressure, the control component 500 closes the solenoid valve 31 and the pressure regulating valve 200 to stop supplying gas to the external device. Under the action of the one-way valve 32, the gas inside the external device will not flow back to the gas tank 100.

[0046] If the internal air pressure of the external device is greater than or equal to the predetermined air pressure, the control component 500 keeps the solenoid valve 31 and the pressure regulating valve 200 in a closed state to refuse to replenish air for the external device.

[0047] In a specific application, the pressure regulating valve 200 has a manual adjustment handle, and a pointer pressure gauge is provided on the pressure regulating valve 200. When the solenoid valve 31 is closed and the pressure regulating valve 200 is opened, the pressure transmitter 33 can detect the pressure of the pipeline (gas tank 100) of the pressure regulating valve 200. In a specific application, by detecting the pressure of the gas tank 100, it can be determined whether the conditions for gas replenishment are met. If the pressure of the gas tank 100 does not reach the preset range, the conditions for gas replenishment are not met, and the user can be prompted through the screen 51.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
