At present, the automatic instrument is usually encapsulated inside a closed instrument case. To ensure the visualization of the automatic instrument, a transparent observation window made of glass is provided on the instrument case. However, in the industrial environment where the automatic instrument is used, not only a large amount of dust will adhere to the outer surface of the transparent observation window, but also due to the influence of the temperature difference between the inside and outside of the instrument case, water mist is extremely likely to be generated on the inner side of the transparent observation window, blocking the observation line of sight of the automatic instrument panel and unable to be cleared immediately, seriously affecting the inspection work of the staff on the operation of industrial equipment. In addition, in relatively cold outdoor occasions, a thick layer of frost will be generated on the surface of the transparent observation window. When using sharp objects to scrape and clean the frost, it will cause damage to the observation window of the automatic instrument. Summary of the Utility Model

Specific embodiments

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0028] Such as Figure 1-7As shown in the figure, the present utility model provides an anti-fog automatic instrument, including a back plate 10; the back plate 10 is connected to the rear side of the instrument sealing shell 1 by bolts; it also includes an observation window 3, an outer rotating rod 4, a brush strip 6, a knob 7, a switch button 8, a measuring instrument 9, an external power supply wiring socket 14, a transmission rod 17 and an inner rotating rod 18; the knob 7 is welded to the right end of the worm 15; the measuring instrument 9 is adhered to the back plate 10; the external power supply wiring socket 14 is connected to the power controller 16 by a wire; the power controller 16 is connected to the instrument sealing shell 1 by bolts, and the power controller 16 is connected to the observation window 3 by a wire; the outer side of the observation window 3 is adhered to the inner side of the window frame 2 by sealant; the window frame 2 is connected to the front end of the instrument sealing shell 1 by screw meshing; on the inner side of the instrument sealing shell 1 near the front end, there are a thread and an annular chute in sequence from front to back, and the rotating wheel 11 is embedded in the chute of the instrument sealing shell 1; the outer rotating rod 4 is welded to the front end of the connecting column 5, and the outer rotating rod 4 is adhered to the brush strip 6; the inner rotating rod 18 is welded to the outer side of the inner plug rod 13, and the inner rotating rod 18 is adhered to the sponge gasket strip 12; the connecting column 5 is rotatably connected to the observation window 3, and the connecting column 5 and the inner plug rod 13 are inserted into each other; the left end of the transmission rod 17 is welded to the outer side of the inner plug rod 13, and the right end of the transmission rod 17 is welded to the inner side of the rotating wheel 11.

[0029] A through hole is provided at the center position of the observation window 3, the connecting column 5 is rotatably connected in the through hole of the observation window 3, the observation window 3 is made of double-layer tempered glass, and a tin dioxide conductive coating layer is provided inside the glass. By using the power controller 16 to continuously supply power to the tin dioxide conductive coating layer inside the observation window 3, heat is generated in the conductive film to complete the heating and temperature-rising work of the observation window 3, preventing the surface of the observation window 3 from icing.

[0030] When the utility model conducts the observation and measurement work of the automatic instrument, if there is water mist attached to the inner surface of the observation window 3, making it difficult to observe the measurement numbers of the automatic instrument, the observer can manually rotate the knob 7. The knob 7 drives the worm 15 to rotate. Since the worm 15 meshes with the spiral teeth on the outer side of the rotating wheel 11, the worm 15 can drive the transmission rod 17 welded to the inner side of the rotating wheel 11 to rotate around the central axis of the observation window 3. The transmission rod 17 drives the inner insertion rod 13 to rotate, and the inner insertion rod 13 drives the inner rotating rod 18 welded to the outer side to rotate. At this time, the sponge cushion strip 12 adhered to the front side of the inner rotating rod 18 fits against the inner surface of the observation window 3 and performs a rotational movement. The sponge cushion strip 12 adsorbs and wipes off the water mist on the surface of the observation window 3 through its porous structure. Since the front end tenon structure of the inner insertion rod 13 is inserted into the rear end of the connecting column 5, the inner insertion rod 13 can drive the outer rotating rod 4 welded to the outer side of the connecting column 5 to rotate synchronously. The outer rotating rod 4 carries the brush strip 6 to wipe off the floating dust on the outer side of the observation window 3, keeping the observation field of the automatic instrument clean. If the automatic instrument is in a cold environment and the surface of the observation window 3 of the automatic instrument freezes and cannot be observed, the external power supply can be first plugged into the external power supply connection socket 14, and then the switch button 8 is manually pressed. The switch button 8 activates the power controller 16 to energize the tin dioxide coating inside the observation window 3. The tin dioxide starts to generate heat and heats both the inner and outer sides of the observation window 3, quickly melting the ice and frost on the surface of the observation window 3, facilitating the observer to observe the data of the automatic instrument.

[0031] The outer side of the rotating wheel 11 is provided with a spiral tooth structure. The worm 15 is meshed and connected to the outer tooth structure of the rotating wheel 11. The worm 15 drives the transmission rod 17 welded to the rotating wheel 11 to rotate around the central axis of the rotating wheel 11, realizing the rotational wiping work of the inner rotating rod 18 on the surface of the observation window 3. The transmission structure is compact, and the operation is fast and simple.

[0032] The outer side of the window frame 2 is provided with threads. The threads on the outer side of the window frame 2 mesh with the threads on the inner side of the instrument sealing shell 1, realizing the split-type combined connection of the observation window 3 and the instrument sealing shell 1. If the observation window 3 is damaged, the window frame 2 can carry the observation window 3 for disassembly, maintenance and replacement without removing the instrument sealing shell 1 and the measuring instrument 9.

[0033] The sponge cushion strip 12 is adhered to the front side of the inner rotating rod 18 through Velcro. The front side of the sponge cushion strip 12 closely fits against the rear side of the observation window 3. Through the good water absorption characteristics of the sponge porous structure, the water droplets and fog on the inner surface of the observation window 3 are adsorbed and wiped off, ensuring a good measurement observation field of view.

[0034] The front side of the brush strip 6 is adhered to the rear side of the outer rotating rod 4 through Velcro. The fluffy end of the brush strip 6 is arranged on the front side of the observation window 3. The outer rotating rod 4 drives the brush strip 6 to rotate around the central axis of the observation window 3, so that the brush strip 6 comprehensively wipes the dust on the outer surface layer of the observation window 3.

[0035] A groove is provided at the rear end of the connecting column 5. The tenon structure at the front end of the inner insertion rod 13 is inserted into the groove of the inner insertion rod 13. Under the detachable structure of the instrument sealing shell 1 and the window frame 2, the inner insertion rod 13 drives the inner rotating rod 18 and the outer rotating rod 4 to rotate synchronously through the tenon structure, completing the synchronous wiping operation of the water mist inside the observation window 3 and the dust outside.

[0036] The installation methods, connection methods or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc. And the specific structures, models and coefficient indexes of all their components are their own technologies, and any that can achieve their beneficial effects can be implemented. The above-mentioned switch button 8, measuring instrument 9, and power controller 16 are all common devices on the market. When purchased and used, only need to be connected according to the user manual purchased together to be used, so it will not be elaborated here.
