Description

Technical Field

[0001] This utility model relates to the technical field of SF6 detection devices, and in particular to an infrared detection device that combines SF6 and O2. Background Technology

[0002] In the power industry, sulfur hexafluoride (SF6) is widely used in conductive equipment such as power switches, enclosed capacitor banks, and transformers. During equipment operation, SF6 gas leakage is inevitable. To avoid excessive SF6 leakage and to quickly repair any leaks, it is essential to install SF6 gas detection systems.

[0003] A search revealed that Chinese patent CN219737267U discloses a dual-function infrared detection device for SF6 and O2, comprising a wall-mounted base, a crossarm bracket, an oxygen detection component, and an SF6 gas infrared detection component. The crossarm bracket has a crossbar and a shaft connection. The wall-mounted base has a bushing for connecting the shaft connection, and the shaft connection is rotatably connected to the bushing. The oxygen detection component and the SF6 gas infrared detection component are mounted on the crossbar. The front end of the crossbar has a rotating platform, on which the SF6 gas infrared detection component is mounted. An alarm is provided on the crossbar or the wall-mounted base, and the alarm is triggered when the SF6 gas infrared detection component detects an SF6 gas leak.

[0004] The aforementioned publicly available document adopts a wall-mounted installation, and the detection device has the function of angle and position adjustment. Although it is different from the traditional floor-mounted installation, it still has some shortcomings in actual use. For example, its installation method is only different from the floor-mounted installation by changing to a wall-mounted installation, but its device only has the function of wall-mounted installation. If a floor-mounted installation is required, its structure is not sufficient to meet this requirement, resulting in poor applicability and a limited range of use scenarios.

[0005] To address the aforementioned shortcomings, this application proposes a dual infrared detection device combining SF6 and O2. Utility Model Content

[0006] This invention provides a dual-function infrared detection device for SF6 and O2 to solve the aforementioned technical problems.

[0007] To solve the above-mentioned technical problems, this utility model provides an SF6 and O2 dual-infrared detection device, including a base, a sulfur hexafluoride sensor and an oxygen sensor. A telescopic rod is installed in front of the base, a first joint is installed between the base and the telescopic rod, an installation plate is installed in front of the telescopic rod, a second joint is installed between the telescopic rod and the installation plate, and the sulfur hexafluoride sensor and the oxygen sensor are both fixedly installed in front of the installation plate.

[0008] A groove is provided on the rear edge of the base, and an extension leg is movably connected to each of the four corners of the bottom of the base via a damping pivot. The extension leg is located inside the groove.

[0009] The base has four rectangular bolt holes on its front side.

[0010] Preferably, the first joint includes a U-shaped seat, which is fixedly connected to the center of the front side of the base. A rotating block is movably connected inside the U-shaped seat via a rotating shaft. The rotating block is fixedly connected to the rear side of the telescopic rod. A hand-tightening screw is threadedly connected to the bottom of the U-shaped seat, and the end of the hand-tightening screw abuts against the bottom of the rotating block.

[0011] Preferably, a controller is fixedly connected to the front side of the mounting plate. The controller is located on one side of the sulfur hexafluoride sensor and the oxygen sensor. The sulfur hexafluoride sensor is located above the oxygen sensor. The sulfur hexafluoride sensor and the oxygen sensor are electrically connected to the controller, respectively.

[0012] Preferably, a pad is fixedly connected to one side of the rear pivot of the extended support leg, and the rear side of the pad is at the same level as the bottom of the base.

[0013] Preferably, a connecting block is fixedly connected to the center of the rear side of the mounting plate.

[0014] Compared with related technologies, the SF6 and O2 dual-infrared detection device provided by this utility model has the following advantages:

[0015] Beneficial effects:

[0016] By drilling bolt holes in the base, the device can be wall-mounted. By adding four foldable extension legs, the device can be placed stably on the ground.

[0022] Implementation examples, by Figure 1-4 As shown, this utility model includes a base 1, a sulfur hexafluoride sensor 7 and an oxygen sensor 8. A telescopic rod 3 is installed in front of the base 1. A first joint 2 is installed between the base 1 and the telescopic rod 3. An installation plate 6 is installed in front of the telescopic rod 3. A second joint 4 is installed between the telescopic rod 3 and the installation plate 6. The sulfur hexafluoride sensor 7 and the oxygen sensor 8 are both fixedly installed in front of the installation plate 6.

[0023] A groove 10 is provided at the rear edge of the base 1, and an extension leg 11 is movably connected to each of the four corners of the bottom of the base 1 via a damping pivot. The extension leg 11 is located inside the groove 10.

[0024] The base 1 has four rectangular bolt holes 13 on its front side.

[0025] The first joint 2 includes a U-shaped seat 21, which is fixedly connected to the center of the front side of the base 1. A rotating block 22 is movably connected inside the U-shaped seat 21 via a pivot. The rotating block 22 is fixedly connected to the rear side of the telescopic rod 3. A hand-tightening screw 23 is threaded to the bottom of the U-shaped seat 21, with its end abutting against the bottom of the rotating block 22. After adjusting the angle of the telescopic rod 3, the first joint 2 can be fixed in place by tightening the hand-tightening screw 23, preventing further rotation. The structure of the second joint 4 is exactly the same as that of the first joint 2, and therefore will not be described further here.

[0026] A controller 9 is fixedly connected to the front side of the mounting plate 6. The controller 9 is located on one side of the sulfur hexafluoride sensor 7 and the oxygen sensor 8. The sulfur hexafluoride sensor 7 is located above the oxygen sensor 8. The sulfur hexafluoride sensor 7 and the oxygen sensor 8 are electrically connected to the controller 9. The sulfur hexafluoride sensor 7 and the oxygen sensor 8 are both existing technology products and can be used to detect the content of SF6 and O2, respectively. Therefore, their structure and working principle will not be described in detail here. The data detected by the sulfur hexafluoride sensor 7 and the oxygen sensor 8 will be transmitted to the controller 9.

[0027] A pad 12 is fixedly connected to one side of the pivot shaft on the rear side of the extension leg 11. The rear side of the pad 12 is at the same level as the bottom of the base 1. After the extension leg 11 is extended, the pad 12 helps to raise the extension leg 11 so that it can be placed more stably on the ground with the base 1, making the device more stable when placed on the ground.

[0028] A connecting block 5 is fixedly connected to the center of the rear side of the mounting plate 6. The connecting block 5 is mainly connected to the rotating block in the second joint 4 so that the second joint 4 can adjust the angle of the mounting plate 6.

[0029] Working principle:

[0030] During installation, the device can be placed on the ground or wall-mounted as needed. For wall-mounted installation, simply fix the base 1 to the wall by passing bolts through bolt holes 13. At this time, the sulfur hexafluoride sensor 7 and oxygen sensor 8 on the mounting plate 6 can be adjusted in left-right, front-back, and up-down angles and positions via the first joint 2, telescopic rod 3, and second joint 4. When placing it on the ground, simply unfold the four extension legs 11 on the base 1 to extend them to the four corners of the base 1. At this time, the base 1 and the four extension legs 11 rest on the ground, giving the telescopic rod 3 and the sulfur hexafluoride sensor 7 and oxygen sensor 8 on the mounting plate 6 good stability. The mounting plate 6 can still be adjusted in height via the telescopic rod 3 and in angle via the second joint 4. The first joint 2 is used to keep the telescopic rod 3 in a vertical position.
