[0036] Embodiment 2 further optimizes the extreme environment resistant sensor device provided in Embodiment 1. Specifically, Figure 1-Figure 3 As shown, a protection mechanism 3 is provided on the outer surface of the sensor probe 1 , and the protection mechanism 3 is used for protecting the sensor probe 1 , and the protection mechanism 3 is also used for installing the sensor probe 1 .

[0037] Further, such as Figure 1-Figure 3 As shown, the protection mechanism 3 includes a fixing base 301 fixedly connected to the outer surface of the sensor probe 1, and a plurality of mounting holes 314 are opened on the fixing base 301. During installation, the fixing base 301 can be fixed on the installation object by passing the mounting bolts through the mounting holes 314 to achieve installation.

[0038] Further, such as Figure 1-Figure 3 As shown, side grooves 302 are provided on both sides of the fixing seat 301, connecting shafts 303 are fixedly connected in the two side grooves 302, connecting seats 304 are sleeved on the outer surfaces of the two connecting shafts 303, and protective boxes 305 are provided on one side of the two connecting seats 304. The sensor probe 1 is located between the two protective boxes 305, that is, the sensor probe 1 can be protected by the two protective boxes 305.

[0039] Further, such as Figure 3As shown, grooves are provided on the sides of the two protective boxes 305 that are close to each other, the sensor probe 1 is located between the two grooves, and protective plates 311 are fixedly connected in the two grooves. The arrangement of the grooves enables the sensor probe 1 to be protected between the two protective boxes 305, so that the two protective boxes 305 can protect the sensor probe 1 when the sensor probe 1 is not installed and used.

[0040] Further, such as Figure 1-Figure 3 As shown, the top ends of the two connecting shafts 303 both pass through the sensor connecting wires 101 and are both provided with connecting plates 309 through bearing sleeves. A first T-shaped slot 306 is provided on the top of the protective box 305. A limiting plate 307 is slidably connected in the first T-shaped slot 306. A threaded rod 308 is fixedly connected to the top of the limiting plate 307. The top end of the threaded rod 308 passes through the connecting plate 309, and a hand nut 310 is threadedly connected to the outer surface of the threaded rod 308.

When the sensor probe 1 is in use, the two protection boxes 305 are rotated to the rear of the fixing seat 301 so that the two protection boxes 305 can tighten and fix the protective sleeve 5. At this time, the situation in which the sensor connecting line 101 is separated from the sensor probe 1 due to external force can be reduced, that is, the protection box 305 can protect the sensor probe 1 when it is not installed and used, and fix the sensor connecting line 101 when the sensor probe 1 is in use. The setting of the card slot 4 can increase the contact area between the protection box 305 and the protective sleeve 5 to improve the fixing effect of the protective sleeve 5, and the setting of the protective sleeve 5 can avoid the situation in which the protection box 305 directly clamps the sensor connecting line 101 and damages the sensor connecting line 101.

[0044] When used, the form of this application is changed from Figure 1 Switch to Figure 5 Specifically, first loosen the hand nut 310, then rotate the protective box 305 to the back of the fixing seat 301 with the connecting shaft 303 as the center, and then push the two protective boxes 305 close to each other so that the two protective boxes 305 clamp the protective sleeve 5. At this time, the protective sleeve 5 is located in the card slot 4, and then tighten the hand nut 310 to fix the position of the protective box 305. Figure 5 As shown, at this time, the present application can be installed on the corresponding installation object by passing the bolts through the installation holes 314;

[0045] After the fixing base 301 is removed from the mounting object, the hand nut 310 is loosened to push the two protection boxes 305 away from each other, and then the protection box 305 is rotated to the front of the fixing base 301 with the connecting shaft 303 as the center. At this time, the two protection boxes 305 can cover the sensor probe 1, and then the hand nut 310 is tightened to fix the position of the protection box 305. Figure 1 As shown, the sensor probe 1 can be protected by the protection box 305 at this time.
