By plugging the two together, the outer protective cover 3 and the inner protective cover 2 are relatively fixed, and the insertion rod 7 can be adjusted to insert into the adjustment slot 4 of the corresponding height to form an adjustment of the overall protection effect, and the same blocking piece 8 is fixed at the ends of the two corresponding guide rods 5 to form two blocking pieces 8, and the two blocking pieces 8 are fixed on the side where they are close to each other with a return spring 9, and the ends of the two return springs 9 close to each other are fixedly connected to the two linkage plates 6 respectively, and the elastic top force of the return spring 9 can be used to tightly insert the insertion rod 7 into the adjustment slot 4.

[0022] In the above method, in order to be able to drive the two linkage plates 6 to move away from each other so as to bring the insertion rod 7 out of the adjustment groove 4, a toothed bar 10 is provided on the top of the two linkage plates 6, and a concave seat 11 is fixed on the outer walls on both sides of the outer protective cover 3, and a transmission rod 12 is rotatably installed in the two concave seats 11, and a toothless round tooth 13 is fixedly sleeved on the two transmission rods 12, and the two toothless round teeth 13 are respectively adapted to the two toothed bars 10. When the teeth of the two are in contact and meshing, the rotation of the transmission rod 12 can drive the toothed bar 10 and the linkage plate 6 to move. In addition, in order to increase the electric drive of the transmission rod 12, a motor 1 is fixed on the outer wall of one side of the two concave seats 11, and the output shafts of the two motors 1 are respectively fixedly connected to the ends of the two transmission rods 12.

[0023] In this method, in order to conveniently and quickly scrape off the dust on the filter plate 15 to ensure the filtering performance of the filter plate 15, folding strips 16 are fixed on the outer walls of both sides of the outer protective cover 3, and a driven shaft 17 is rotatably installed on the two folding strips 16. A scraping piece 18 is fixed on the end of the two driven shafts 17 close to each other, and the two scraping pieces 18 are in contact with the two filter plates 15 on the sides close to each other, and a connecting frame 19 is fixed on the top of the outer protective cover 3. The same active rod 20 is rotatably installed on both sides of the connecting frame 19, and a driven shaft 21 is rotatably installed on the top of the two folding strips 16.

At this point, by utilizing the operation of the motor 2 and the meshing transmission of various gears, the two scraping sheets 18 can remove the flocculent dust impurities attached to the filter plate 15.

[0024] The working principle of the protection structure of the natural gas pressure regulating skid provided by the utility model is as follows:

[0025] When protecting the voltage regulating skid, the components such as the voltage regulating skid, the instrument, and the pipeline on the skid seat 1 are all located inside the inner protective cover 2, so that a good protective effect is formed through the cooperation between the inner protective cover 2 and the outer protective cover 3;

[0026] When the device is required to be used on a pressure regulating skid with a higher natural gas pipeline, before the inner protective cover 2 is installed on the skid seat 1, the two motors 1 are started first, and the output shafts of the two motors 1 respectively drive the two transmission rods 12 to rotate, and then can drive the missing tooth round teeth 13 to rotate. When the teeth of the missing tooth round teeth 13 contact the teeth on the tooth bar 10, the two are meshed, and the two tooth bars 10 move away from each other, thereby causing the two linkage plates 6 to move away from each other, and finally bringing the two plug rods 7 out of the corresponding adjustment slots 4. At this time, the two motors 1 are turned off, and the two return springs 9 are pressed and slightly compressed;

[0027] Then, the outer protective cover 3 is slid upward. After the outer protective cover 3 is moved up to the specified height, the two insertion rods 7 are respectively horizontally aligned with the adjustment slots 4 of the corresponding heights, and the two motors 1 are randomly started again. The two toothed bars 10 continue to move away from each other until the teeth on the missing tooth round teeth 13 are separated from the teeth on the toothed bar 10. The compressed return spring 9 releases its elastic force, causing the two linkage plates 6 to move quickly toward each other, and finally the two insertion rods 7 are brought into the corresponding adjustment slots 4, thereby completing the adjustment of the outer protective cover 3.

[0028] Then, place the inner protective cover 2 on the skid seat 1 from top to bottom, so that the various components on the voltage regulating skid are inside it, and then install it on the skid seat 1 by means of bolts or the like;

[0029] At the same time, during daily protection, the vent 14 can ensure air circulation inside the inner protective cover 2 and the outer protective cover 3 to ensure the heat dissipation function. When more dust accumulates on the filter plate 15 and affects the ventilation, the motor 2 can be started. Through the engagement of the full-tooth round tooth 1 and the full-tooth round tooth 2, the active rod 20 can be driven to rotate. At the same time, the engagement of the bevel tooth 1 and the bevel tooth 2, and the engagement of the bevel tooth 3 and the bevel tooth 4 can be used to drive the scraper 18 to rotate, so that the dust attached to it can be scraped off, thereby ensuring the ventilation effect to a certain extent.
