[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-8 The utility model provides a technical solution: a high-temperature resistant system gas path protection device, including a sensor body 1, an extension block 2 is installed at the bottom of the sensor body 1, and also includes a carrying frame 3, a fastening mechanism is provided between the carrying frame 3 and the extension block 2; the fastening mechanism includes a first clamping plate 5 and a second clamping plate 6 slidingly connected to both sides of the carrying frame 3, the first clamping plate 5 and the second clamping plate 6 are connected by a linkage 7, and a fixing groove 4 is opened on the bottom of the extension block 2, and the first clamping plate 5 and the second clamping plate 6 fix the carrying frame 3 and the extension block 2 through the fixing groove 4.

[0030] Specifically, the high-temperature resistant system gas path protection device includes a sensor body 1. The sensor body 1 is a prior art, and its structure and working principle are not described in detail here. An extension block 2 is installed at the bottom of the sensor body 1, that is, the sensor body 1 is installed on a predetermined device through the extension block 2. It also includes a carrier frame 3, and a fastening mechanism is provided between the carrier frame 3 and the extension block 2, that is, the sensor body 1 is installed inside the carrier frame 3 through the fastening mechanism to meet working needs. The fastening mechanism includes a first card plate 5 and a second card plate 6 that are slidably connected on both sides of the carrier frame 3. The first card plate 5 and the second card plate 6 are connected by a linkage 7. That is, when the first card plate 5 moves, the second card plate 6 will be driven to move by the linkage 7. A fixing groove 4 is provided on the bottom of the extension block 2. Specifically, the first card plate 5 and the second card plate 6 fix the carrier frame 3 and the extension block 2 through the fixing groove 4. The first and second clips 5, 6 are both L-shaped, and the fixing slot 4 is also L-shaped, allowing for better mounting of the sensor body 1 within the carrier frame 3 and providing improved performance. When the sensor needs to be removed from a given device for inspection and maintenance, the first clip 5 is driven to slide, and during this sliding stroke, the second clip 6 is driven to move via the linkage 7, allowing the first and second clips 5, 6, to slide out of the fixing slot 4, respectively. This allows the sensor body 1 to be removed for inspection and maintenance, greatly improving the practicality of the sensor body 1 and providing improved performance.

[0031] In the embodiment provided by the present utility model, the linkage member 7 includes a linkage rod rotatably connected to the bottom of the carrier frame 3, a linkage gear 7.2 is provided on the linkage rod, and a first rack 7.1 is installed on the first clamping plate 5, and a second rack 7.3 is installed on the second clamping plate 6. The first rack 7.1 and the second rack 7.3 are respectively clamped on both sides of the linkage rack to meet working needs.

[0032] In the embodiment provided by the present invention, a pressure rod 9 is fixedly connected to the first clamping plate 5 , and the pressure rod 9 is slidably connected to the carrying frame 3 to facilitate driving the first clamping plate 5 to slide.

[0033] In the embodiment provided by the present invention, a positioning spring 8 is provided between the second clamping plate 6 and the supporting frame 3. The elastic force of the positioning spring 8 drives the first clamping plate 5 and the second clamping plate 6 to be respectively clamped in the fixing groove 4, fixing the extension block 2, thereby improving the stability of the sensor body 1 during installation and achieving better use effect.

[0034] In the embodiment provided by the present invention, limiting portions are provided between the first clamping plate 5 , the second clamping plate 6 and the carrying frame 3 to improve the stability of the first clamping plate 5 and the second clamping plate 6 when sliding.

[0035] In the embodiment provided by the present invention, a locking member is provided between the first clamping plate 5 and the second clamping plate 6 for fixing the first clamping plate 5 and the second clamping plate 6 .

[0036] In the embodiment provided by the present invention, the locking member includes a fixing rod 10 fixedly connected to the first clamping plate 5, a locking block 11 is provided on the fixing rod 10, and an adapting groove 12 adapted to the locking block 11 is provided on the second clamping plate 6, and the locking block 11 is slidably connected to the adapting groove 12; and a clamping member is provided between the second clamping plate 6 and the locking block 11. By providing the clamping member, the state of the first clamping plate 5 and the second clamping plate 6 can be fixed, thereby facilitating the installation and disassembly of the sensor body 1 and achieving better use effect.

[0037] In the embodiment provided by the present invention, the clamping member includes a clamping block 14 slidably connected to the second clamping plate 6, a clamping groove 13 is provided on the locking block 11, and a pressure spring 15 is provided between the clamping block 14 and the second clamping plate 6. The elastic force of the pressure spring 15 drives the clamping block 14 to be clamped in the clamping groove 13, fixing the locking block 11 in the second clamping plate 6. Therefore, when the sensor body 1 needs to be disassembled, the first clamping plate 5 and the second clamping plate 6 are driven close to each other, and then the locking block 11 will slide in the adapter groove 12 until the clamping block 14 is clamped in the clamping groove 13, fixing the locking block 11, thereby facilitating the disassembly of the sensor body 1, and after the sensor body 1 is disassembled, the first clamping plate 5 and the second clamping plate 6 are still in a close state, so it is convenient to install the sensor body 1 in the predetermined position later, and the use effect is better.

[0038] In the embodiment provided by the present invention, an elastic portion 16 is provided on one side of the engaging block 14, and one side of the elastic portion 16 abuts against the engaging slot 13. Specifically, the elastic portion 16 is made of an elastic material. When the force exerted by the locking block 11 during reverse sliding is greater than the elastic force of the elastic portion 16, the engaging slot 13 and the engaging block 14 abut and squeeze the elastic portion 16, causing the elastic portion 16 to deform, allowing the locking block 11 to smoothly disengage from the adapting slot 12, thus meeting operational requirements. More specifically, the elastic force of the positioning spring 8 is less than that of the elastic portion 16. Therefore, in the absence of an external force, the positioning spring 8 cannot cause the elastic portion 16 to deform.

[0039] In the embodiment provided by the present invention, the sensor body 1 and the extension block 2 are connected by bolts, thereby facilitating the disassembly of the sensor body 1 and the extension block 2 to meet work needs.

[0040] The present invention also provides an embodiment in which:

[0041] refer to Figure 8 To optimize system piping connections and reduce plant losses, the device features a pipeline consisting of a powder inlet and an air inlet and outlet. A solenoid valve is installed at the powder inlet, and the pipeline is connected to the powder inlet of the main unit via a quick-connect socket. When the solenoid valve is connected to the device's control system, the channel can be controlled by remotely switching the valve on and off.

[0042] A manual air valve is provided between the solenoid valve and the equipment (to avoid hazards caused by failure of the solenoid valve). The air intake part is connected to the oil-water separator from the external air inlet (which can separate the moisture in the gas, keep the dust dry, and make the detection data more accurate), and then connected to the electronic reversing valve (directly connected to the dust sensor body 1 during normal operation. If the sensor body 1 needs to be removed for inspection or maintenance, the air valve reversal can be controlled at the control end, and the solenoid valve is opened and closed, and directly connected to the air outlet). A manual air valve is provided between the electronic reversing valve and the sensor body 1. The electronic reversing valve is directly connected to the air outlet with a solenoid valve and a manual air valve (double protection measures are provided to ensure the reliability and safety of the air circuit). The air pipe of the air intake part is connected to the high-temperature resistant dust concentration sensor body 1 by a quick plug connector, and the air outlet part is connected to the solenoid valve and the dust sensor body 1 for control on and off. A manual air valve is provided between the solenoid valve and the air outlet for manual control, and the air outlet part is connected to the high-temperature resistant dust concentration sensor body 1 by a quick plug connector.

[0043] Through the above improvements, the air path protection measures of the high-temperature resistant dust sampling system can be greatly optimized. When the high-temperature resistant sensor body 1 in the system needs to be replaced and repaired, the sensor body 1 can be removed promptly and quickly without affecting the normal operation of the air path, thus avoiding the disadvantages of causing the factory to stop working for repairs, greatly avoiding the loss of the factory, and realizing a system that is more in line with actual conditions.
