When it is hit, it can also protect the internal differential pressure transmitter body 2 from shaking to avoid some damage, thereby increasing the protection effect of the equipment, reducing the failure rate of the equipment, and recovering certain economic losses. The protective box 1 is fixedly connected with a protective glass 17, the bottom of the protective rubber pad 121 contacts the differential pressure transmitter body 2, and the bottom of the differential pressure transmitter body 2 contacts the fixed block 2 15, and the left and right sides of the fixed block 2 15 are fixedly connected with support Bracket 14, the front side of fixed block 15 is fixedly connected with fixed card block 151, the back side of fixed block 15 is slidably connected with movable card block 152, the back side of fixed card block 151 is fixedly connected with threaded rod 153, the outer surface of threaded rod 153 is threadedly connected with rotating rod 16, the outer surface of threaded rod 153 is sleeved with spring 2 154, the front and back sides of spring 2 154 are respectively fixedly connected with the back side of fixed card block 151 and the front side of movable card block 152, the right side of protective box 1 is fixedly connected with motor 3, the left side output end of motor 3 is fixedly connected with threaded rod 2 31, the outer surface of threaded rod 2 31 is threadedly connected with threaded slider 32, the inner side of threaded slider 32 is slidably connected with limit rod 33, the top of threaded slider 32 is fixedly connected with connecting rod 34, the outer surface of connecting rod 34 A cleaning rod 35 is fixedly connected. By setting the cleaning rod 35, specifically, the motor 3 is started to make the threaded rod 2 31 drive the threaded slider 32 to move to the left inside the protective box 1, so that the cleaning rod 35 on the top of the threaded slider 32 cleans the internal protective glass 17, and the cleaned dust and steam will fall into the collecting port 36 at the bottom. As the groove opened at the bottom falls, the inside of the equipment can be kept clean, which reduces some harm to the equipment and will not be affected by external factors during detection, thereby improving the detection quality and reducing the aging rate of the equipment. A collecting port 36 is set on the front of the threaded slider 32, and an anti-collision block 321 is slidably connected to the inside of the threaded slider 32. A spring three 322 is fixedly connected to the inside of the anti-collision block 321, and the threaded rod 2 31 is rotatably connected to the inner wall of the protective box 1.The limit rod 33 is fixedly connected to the inner wall of the protection box 1, and the front and back of the differential pressure transmitter body 2 are in contact with the back of the fixed block 151 and the front of the movable block 152 respectively.

[0030] A specific application of this embodiment is as follows: first, pull the sliding block 113 forward to make the fixed block 112 leave the inside of the sliding block 113, then pull the handle 111 to open the protective cover 11, put the differential pressure transmitter body 2 above the fixed block 15, make one side of the differential pressure transmitter body 2 close to the fixed block 151, rotate the rotating rod 16 to make the movable block 152 close to the fixed block 151 to complete the fixation of the differential pressure transmitter body 2, and when the fixation is completed, cover the protective cover 11 to make the pressure block The protective rubber pad 121 at the bottom of 12 contacts the top of the differential pressure transmitter body 2. The spring 131 set on the top of the pressure block 12 can be used to slow down the shaking of the protective box 1 caused by the collision, so that the internal differential pressure transmitter body 2 will not deviate during measurement. Then push the sliding block 113 back to fix the protective cover 11 to prevent the protective cover 11 from being pushed open due to the elastic force brought by the spring 131, and then it can't play a protective role. When the differential pressure transmitter body 2 needs to be disassembled, it only needs to be reversed. By rotating the rotating rod 16, the spring 2 154 inside the fixed block 2 15 will rebound and push the movable block 152 to the back, so that the differential pressure transmitter body 2 is unlocked and can be taken out. After the protective box 1 has been used for a long time, dust and some steam will appear inside, which will adhere to the surface of the protective glass 17 so that the differential pressure transmitter body 2 inside cannot be seen clearly. At this time, it is only necessary to start the motor 3 to make the threaded rod 2 31 drive the threaded slider 32 to move to the left inside the protective box 1. When it moves to the leftmost side, the anti-collision block 321 on the right will contact the inside of the protective box 1, and the spring 322 will be used for buffering to prevent the cleaning rod 35 from being damaged due to excessive movement speed. When it moves to the leftmost side, the same as above is used to make the cleaning rod 35 on the top of the threaded slider 32 clean the internal protective glass 17. The cleaned dust and steam will fall into the collecting port 36 at the bottom, and fall through the notch opened at the bottom. By repeatedly moving the threaded slider 32, the surface of the protective glass 17 can be cleaned until the internal differential pressure transmitter body 2 can be seen clearly.
