Technical Field

[0001] This utility model relates to the field of nitrogen addition technology for photoelectric instruments, and in particular to a fully automatic nitrogen filling device for photoelectric instruments. Background Technology

[0002] After prolonged use, photoelectric instruments require nitrogen replenishment using nitrogen filling equipment. However, typical fully automatic nitrogen filling equipment is ineffective at containing liquid nitrogen tanks, posing a risk of damage due to impact. Furthermore, most nitrogen filling equipment lacks auxiliary sealing measures at the connection point between the equipment and the photoelectric instrument, reducing its usability. A mobile nitrogen filling device, with application number "202421151204.0", published on the China Patent Network, reduces the risk of damage to the liquid nitrogen tank through a fully enclosed shell. However, this device only uses a socket and threaded reinforcement method to connect the equipment to the photoelectric instrument, which offers limited improvement in filling and sealing performance, and the threaded disassembly and assembly structure wastes time.

[0004] This utility model also provides a fully automatic nitrogen filling device with the aforementioned photoelectric instrument, comprising: a protective box, the inside of which is provided with a right-angle placement cavity, the left and right parts of which are a tank placement cavity and a conduit receiving cavity, the inside of which is provided with a rubber sleeve and a nitrogen tank, the rubber sleeve being fixedly connected to the inner wall of the tank placement cavity, the nitrogen tank being in close contact with the inner wall of the rubber sleeve, a pressure plate and a solenoid valve being provided above the tank placement cavity, the pressure plate being snapped into the upper end of the tank placement cavity, the surface of the pressure plate being provided with a through hole, the solenoid valve passing through the through hole and being threadedly connected to the outlet pipe of the nitrogen tank, a gas guide pipe being fixedly connected to the surface of the solenoid valve, a vacuum bag being provided at the end of the gas guide pipe away from the solenoid valve, a binding strip being fixedly connected to the surface of the vacuum bag, when using the device, the connection node between the gas guide pipe and the photoelectric instrument is located inside the vacuum bag, the inside of the conduit receiving cavity is provided with a convex pressure block, the gas guide pipe passing through the lower end of the convex pressure block and connecting to the photoelectric instrument.

[0005] According to the present invention, a fully automatic nitrogen filling device for photoelectric instruments includes a sealing plate at the upper end of the protective box, and the front wall of the protective box is penetrated by a conduit receiving cavity. This improves the sealing effect of the right-angle placement cavity.

[0006] According to the present invention, a fully automatic nitrogen filling device for a photoelectric instrument includes a limiting groove on the inner wall of the conduit receiving cavity, with the gas guide tube located inside the limiting groove. This improves the stability of the gas guide tube during operation.

[0007] According to the fully automatic nitrogen filling device for photoelectric instruments described in this utility model, the height of the convex pressure block is the same as the depth of the conduit receiving cavity. When the nitrogen filling device is not used, the upper surface of the convex pressure block is in contact with the lower surface of the sealing plate, thereby increasing the load-bearing capacity of the sealing plate.

[0008] According to the present invention, a fully automatic nitrogen filling device for photoelectric instruments has a convex pressure block whose lower end is engaged with the inner wall of the conduit receiving cavity. When using the device, the gas guide tube passes through the convex pressure block; when moving the device, the gas guide tube is wrapped around the surface of the convex pressure block.

[0010] According to the fully automatic nitrogen filling device for photoelectric instruments described in this utility model, the lower surface of the pressure plate is in close contact with the upper end of the nitrogen tank, and the diameter of the through hole is larger than the diameter of the lower end of the solenoid valve and the outlet pipe of the nitrogen tank. This improves the limiting effect of the pressure plate on the nitrogen tank.

[0011] According to the present invention, a fully automatic nitrogen filling device for photoelectric instruments includes a storage cavity inside the conduit receiving cavity, and a handheld vacuum pump is installed inside the storage cavity. This improves the convenience of vacuuming operations.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model provides a fully automatic nitrogen filling device for photoelectric instruments, comprising: a protective box 1, with a right-angle placement cavity 2 inside the protective box 1. The left and right parts of the right-angle placement cavity 2 are a tank placement cavity 12 and a conduit receiving cavity 13. The right-angle placement cavity 2 is used to centrally store the nitrogen tank 4 and the gas delivery pipe 10. A sealing plate 11 is provided at the upper end of the protective box 1, and the front wall of the protective box 1 is penetrated by the conduit receiving cavity 13. The sealing plate 11 is used to improve the sealing effect of the right-angle placement cavity 2. The relationship between the conduit receiving cavity 13 and the protective box 1 is to provide ventilation conditions for the right-angle placement cavity 2.

[0023] Specifically, during the use of the equipment, the vertical structure of the tank placement cavity 12 improves the convenience of replacing the nitrogen tank 4, while the sealing plate 11 blocks the upper end of the right-angle placement cavity 2, reducing the contact between the nitrogen tank 4 and external objects, and the protective box 1 is improved by the passage of the conduit receiving cavity 13, thus improving the ventilation effect of the right-angle placement cavity 2.

[0024] The interior of the tank placement cavity 12 is equipped with a rubber sleeve 3 and a nitrogen tank 4. The rubber sleeve 3 is fixedly connected to the inner wall of the tank placement cavity 12, and the nitrogen tank 4 is in close contact with the inner wall of the rubber sleeve 3. The rubber sleeve 3 is used to reduce the impact of the protective box 1 on the nitrogen tank 4 after being hit. A pressure plate 7 and a solenoid valve 9 are provided above the tank placement cavity 12. The pressure plate 7 is snapped into the upper end of the tank placement cavity 12. The surface of the pressure plate 7 is provided with a through hole 8. The solenoid valve 9 passes through the through hole 8 and is threadedly connected to the gas outlet pipe of the nitrogen tank 4. The lower surface of the pressure plate 7 is in close contact with the upper end of the nitrogen tank 4, and the diameter of the through hole 8 is larger than the diameter of the lower end of the solenoid valve 9 and the gas outlet pipe of the nitrogen tank 4. The pressure plate 7 is used to press and fix the tank placement cavity 12 from above, further improving the stability of the nitrogen tank 4.

[0025] Specifically, during the use of the equipment, when the nitrogen filling equipment is moved, the rubber sleeve 3 of the protective box 1 deforms after being hit, which relieves the negative stress on the nitrogen tank 4. The pressure plate 7 increases the stability of the nitrogen tank 4 after it is placed from above. The solenoid valve 9 is connected to the nitrogen tank 4 through the through hole 8, which directly improves the convenience of connecting the gas pipe 10.

[0026] A gas guide tube 10 is fixedly connected to the surface of the solenoid valve 9. The gas guide tube 10 consists of a conduit, a valve connector, and a pressure gauge. The valve connector is fixedly connected to the conduit, and the pressure gauge is fixedly connected to the valve connector. A vacuum bag 14 is provided at the end of the gas guide tube 10 away from the solenoid valve 9. A binding strip 15 is fixedly connected to the surface of the vacuum bag 14. When using the equipment, the connection node between the gas guide tube 10 and the photoelectric instrument is located inside the vacuum bag 14. The vacuum bag 14 and the binding strip 15 cooperate to provide a vacuum seal for the connection node between the equipment and the photoelectric instrument. A storage cavity 16 is provided inside the conduit receiving cavity 13. A handheld vacuum pump 17 is provided inside the storage cavity 16.

[0027] Specifically, during the use of the equipment, after the gas guide tube 10 is connected to the photoelectric instrument socket using the valve connector, the connection point between the two is located inside the vacuum bag 14. Then, the binding strip 15 is used to wrap around and bind the open end of the vacuum bag 14, and the handheld vacuum pump 17 can be used to vacuum the vacuum bag 14, so as to achieve the purpose of sealing and isolating the nitrogen filling connection point.

[0028] The inner wall of the catheter receiving cavity 13 is provided with a limiting groove 5. The air guide tube 10 is located inside the limiting groove 5. A convex pressure block 6 is provided inside the catheter receiving cavity 13. The air guide tube 10 passes through the lower end of the convex pressure block 6 and is connected to the photoelectric instrument. The height of the convex pressure block 6 is the same as the depth of the catheter receiving cavity 13. When the nitrogen filling equipment is not used, the upper surface of the convex pressure block 6 is in contact with the lower surface of the sealing plate 11, and the lower end of the convex pressure block 6 is engaged with the inner wall of the catheter receiving cavity 13. When the equipment is used, the air guide tube 10 passes through the convex pressure block 6. When the equipment is moved, the air guide tube 10 is wrapped around the surface of the convex pressure block 6. The convex pressure block 6 and the limiting groove 5 are used to limit the stability of the air guide tube 10 during use.

[0029] Specifically, during the use of the equipment, pull up the convex pressure block 6 to separate it, and the air guide tube 10 can be pressed into the interior of the limiting groove 5. Then, press down to reset the convex pressure block 6. At this time, the convex pressure block 6 and the limiting groove 5 restrict the range of motion of the air guide tube 10. When using the equipment for short intervals, the air guide tube 10 separated from the photoelectric instrument is wrapped around the convex pressure block 6 for limiting.

[0030] Working principle: When using the equipment, first extend the air guide tube 10 and then press down the convex pressure block 6. In this way, the movement range of the air guide tube 10 is restricted by the limiting groove 5 and the convex pressure block 6. After connecting the air guide tube 10 to the air inlet tube of the photoelectric instrument, the vacuum bag 14 is sealed by the binding strip 15. Then, the air inside the vacuum bag 14 is extracted by the handheld vacuum pump 17, so that the connection node between the air guide tube 10 and the photoelectric instrument is in a vacuum isolation state. At this time, the solenoid valve 9 can be opened to deliver the nitrogen in the nitrogen tank 4 to the inside of the photoelectric instrument. When it is necessary to separate the air guide tube 10, simply open the air inlet of the vacuum bag 14 to change the air pressure of the vacuum bag 14.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
