Description

Technical Field

[0001] This utility model relates to the technical field of gas density meters, specifically a digital remote transmission SF6 gas density meter. Background Technology

[0002] SF6, or sulfur hexafluoride gas, possesses high insulation strength and excellent arc-extinguishing performance, making it the preferred insulating medium for high-voltage equipment. It is widely used in SF6 high-voltage circuit breakers, GIS (Gas Insulation System), SF6 instrument transformers, and SF6 transformers. The density of SF6 gas is one of the key parameters for assessing whether its insulation performance meets the requirements of the corresponding voltage level. Therefore, SF6 gas is widely used in high-voltage electrical equipment such as high-voltage circuit breakers, surge arresters, instrument transformers, transformers, and pipeline busbars as an insulation and arc-extinguishing medium. Electrical components operate within a sealed container filled with SF6 gas, and the density of SF6 gas directly affects the electrical performance of these components, particularly their insulation and arc-extinguishing capabilities. Monitoring the density of SF6 gas involves measuring its pressure and indirectly reflecting the density based on the correlation between pressure and density within a certain temperature range.

[0003] A typical SF6 gas density meter consists of a casing and a connecting pipe. It is used to measure the gas density by connecting the connecting pipe to the pipeline. However, this method is prone to leakage during use because the connecting pipe is assembled by threads or pipe clamps, which reduces the detection accuracy of the SF6 gas density meter and fails to meet the working requirements of the gas density meter. Therefore, a digital remote transmission SF6 gas density meter is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a digital remote transmission SF6 gas density meter, which solves the technical problem that leakage is prone to occur during use due to the connection pipe being assembled by threads or pipe clamps, resulting in a decrease in the detection accuracy of the SF6 gas density meter.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a digital remote transmission SF6 gas density meter, comprising:

[0008] The outer casing has a connecting pipe at its bottom, a connecting frame at its left side, a bolt screwed into the inside of the connecting frame, and a mounting platform at its bottom.

[0009] A snap-fit ​​connector is attached to the bottom of the mounting platform. The snap-fit ​​connector has a cavity on the left side and a sliding groove on the right side. Slide plates are inserted into both the left and right sides of the sliding groove.

[0010] A sealing ring is installed on the right side of the slide plate. The inside of the sealing ring is lined with sealing gaskets. A bearing is installed in the middle of the left side of the snap-fit ​​seat. A rotating shaft is inserted inside the bearing. A transmission disc is coaxially installed on the right end of the rotating shaft.

[0011] Arc-shaped transmission grooves are formed on the left and right sides inside the transmission disc. Insert shafts are inserted into the interior of each arc-shaped transmission groove, and the outer ends of each insert shaft are connected to the corresponding positions on the inner side of the slide plate.

[0012] Preferably, the orientation of the arc-shaped transmission grooves is arranged in an array with the transmission disc circle as the center, and a frustum is coaxially mounted on the left end of the rotating shaft, which facilitates the rotation of the rotating shaft.

[0013] Preferably, a lever is coaxially mounted on the left side of the frustum, and an insertion hole is provided at the center of the top of the frustum.

[0014] Preferably, a pin is inserted into the left side of the inside of the connecting frame, the bottom of the pin is inserted into the inside of the socket, and a lever is installed at the top of the pin, which facilitates pulling the pin.

[0015] Preferably, a spring is fitted around the pin at a position between the connecting frame and the mounting platform. The upper and lower ends of the spring are respectively connected to the corresponding positions on the inner sides of the connecting frame and the mounting platform. The added pin can limit the movement of the frustum and the rotating shaft, preventing them from loosening after the sealing ring is clamped.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a digital remote transmission SF6 gas density meter, which has the following beneficial effects:

[0018] This digital remote-reading SF6 gas density meter assembles the connecting frame and connecting pipe using bolts. Rotating the shaft drives the transmission disc, which in turn drives the insertion shaft synchronously via an arc-shaped transmission groove. This, in turn, causes the sealing ring to open and close synchronously via a sliding plate. This clamps the sealing ring and gasket onto the outside of the connecting pipe, effectively filling minor defects and unevenness on the interface surface. When the sealing ring is clamped, the gasket is uniformly compressed, and its deformation adapts to the geometric features of the interface surface, improving the overall sealing performance of the connection system, effectively preventing SF6 gas leakage, and enhancing the quality of the SF6 gas density meter.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution: a digital remote transmission SF6 gas density meter, comprising a shell 1, a connecting pipe 2, a connecting frame 3, bolts 4, a mounting platform 5, a snap-fit ​​seat 6, a cavity 7, a slide groove 8, a sliding plate 9, a sealing ring 10, a sealing washer 11, a bearing 12, a rotating shaft 13, a transmission disc 14, an arc-shaped transmission groove 15, a insert shaft 16, a frustum 17, a lever frame 18, a socket 19, a pin 20, a spring 21, and a lever 22.

[0029] Please see Figure 1 The bottom of the outer casing 1 is equipped with a connecting pipe 2. Please refer to [link / reference]. Figure 2 A connecting bracket 3 is installed on the left side of the connecting pipe 2. A bolt 4 is screwed into the inside of the connecting bracket 3. Please refer to [link / reference]. Figure 3The bottom of the connecting frame 3 is equipped with a mounting platform 5;

[0030] Please see Figure 3 The snap-fit ​​seat 6 is connected to the bottom of the mounting platform 5. The snap-fit ​​seat 6 has a cavity 7 on the left side and a slide groove 8 on the right side. Slide plates 9 are inserted into both the left and right sides of the slide groove 8.

[0031] A sealing ring 10 is installed on the right side of the slide plate 9. The interior of each sealing ring 10 is lined with a sealing gasket 11. (See attached image.) Figure 3 A bearing 12 is installed in the middle of the left side of the card holder 6. Please refer to [link / reference]. Figure 3 A rotating shaft 13 is inserted inside the bearing 12. Please refer to [link / reference]. Figure 5 A transmission disc 14 is coaxially mounted on the right end of the rotating shaft 13;

[0032] Arc-shaped transmission grooves 15 are formed on the left and right sides inside the transmission disk 14. Insert shafts 16 are inserted into the arc-shaped transmission grooves 15. The outer ends of the insert shafts 16 are connected to the corresponding positions on the inner side of the slide plate 9. The connecting frame 3 and the connecting pipe 2 are assembled by bolts 4. By rotating the rotating shaft 13, the transmission disk 14 is rotated, so that the insert shafts 16 can be driven to move synchronously through the arc-shaped transmission grooves 15. In turn, the sealing ring 10 can be driven to open and close synchronously through the slide plate 9. This allows the sealing ring 10 and the sealing gasket 11 to be clamped on the outside of the connecting pipe 2. This can effectively fill the small defects and unevenness on the interface surface. When the sealing ring 10 is clamped, the sealing gasket 11 is uniformly compressed. Its deformation can adapt to the geometric features of the outer surface of the interface, improve the overall sealing performance of the connection system, effectively prevent the leakage of SF6 gas, and improve the quality of use of the SF6 gas density meter.

[0033] The orientation of the arc-shaped transmission grooves 15 is arranged in an array centered on the circular transmission disc 14. Please refer to [link / reference]. Figure 3 A frustum 17 is coaxially mounted on the left end of the rotating shaft 13, and an actuating bracket 18 is coaxially mounted on the left side of the frustum 17. Please refer to [link / reference]. Figure 7 A socket 19 is provided at the center of the top of the truncated cone 17. Please refer to [link / reference]. Figure 6 A pin 20 is inserted into the left side of the inside of the connecting frame 3. The bottom of the pin 20 is inserted into the inside of the socket 19. A lever 22 is installed at the top of the pin 20. A spring 21 is sleeved on the outside of the pin 20 between the connecting frame 3 and the mounting platform 5. The upper and lower ends of the spring 21 are respectively connected to the corresponding positions on the inside of the connecting frame 3 and the mounting platform 5.

[0034] This solution assembles the connecting frame 3 and the connecting pipe 2 using bolts 4. Rotating the rotating shaft 13 drives the transmission disc 14 to rotate, which in turn drives the insertion shaft 16 to move synchronously via the arc-shaped transmission groove 15. This, in turn, drives the sealing ring 10 to open and close synchronously via the sliding plate 9. This allows the sealing ring 10 and the sealing gasket 11 to be clamped to the outside of the connecting pipe 2, effectively filling minor defects and unevenness on the interface surface. When the sealing ring 10 is clamped, the sealing gasket 11 is uniformly compressed, and its deformation adapts to the geometric features of the interface's outer surface, improving the overall sealing performance of the connection system, effectively preventing SF6 gas leakage, and enhancing the usability of the SF6 gas density meter.
