[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a rust removal device for the maintenance of building fire protection facilities, including a trolley 1. The trolley 1 is the basic support structure of the entire rust removal device, which is easy to move so that the operator can easily push the vehicle. A handle 2 is fixedly connected to the top of the trolley 1. The handle 2 is used by the operator to push and pull the trolley 1. A debris collection mechanism 3 is fixedly connected to the top of the trolley 1. The main purpose of the debris collection mechanism 3 is to collect debris, rust, and other waste materials generated during the rust removal process. A protective mechanism 18 is fixedly connected to the outside of the debris collection mechanism 3. The main purpose of the protective mechanism 18 is to ensure safety during the operation and prevent debris and liquid from splashing onto the operator during the rust removal operation.
[0033] The debris collection mechanism 3 includes a rust removal component, which includes a storage bin 4. The bottom of the storage bin 4 is fixedly connected to the top of the trolley 1. The storage bin 4 stores the sand needed during the sandblasting process. A spray pipe 5 is fixedly connected to the front of the storage bin 4. The spray pipe 5 is used to transport sand and help clean the surface to be rusted. The design of the spray pipe 5 needs to ensure smooth sand transport. A collection box 6 is fixedly connected to the top of the trolley 1. The collection box 6 is used to collect splash water and debris generated during the rust removal operation to keep the work area clean. A suction pump 7 is fixedly connected to both sides of the collection box 6. A suction pipe 8 is fixedly connected to the input end of the suction pump 7. The suction pump 7 collects debris and liquid generated during rust removal into the collection box 6 through the suction pipe 8. A spherical shell 9 is fixedly connected to the front of the suction pipe 8. A fixing ring 10 is fixedly connected to the outside of the spherical shell 9. The fixing ring 10 is used to fix the spherical shell 9.
[0034] A rotating ball 11 is rotatably connected inside the spherical shell 9. The spherical shell 9 can accommodate the rotation of the rotating ball 11 to adjust the angle of the front rotating tube 12 and the suction port 13, thereby effectively sucking up debris. The rotating tube 12 is fixedly connected to the front of the rotating ball 11, and the suction port 13 is fixedly connected to the front of the rotating tube 12. The suction angle of the rotating tube 12 and the suction port 13 can be adjusted by the rotation of the rear rotating ball 11. An adjusting assembly is fixedly connected to the outside of the rotating ball 11. The adjusting assembly includes a support ring 14. The inner side of the support ring 14 is fixedly connected to the outer side of the rotating ball 11. The support ring 14 is used for fixing... A sliding column 15 is fixedly connected to the bottom of the rotating tube 12 and the support ring 14. A base 16 is slidably connected to the outside of the sliding column 15. The bottom of the base 16 is fixedly connected to the top of the trolley 1. The sliding column 15 slides inside the base 16 to adjust the height of the rotating tube 12. A limit shaft 17 is slidably connected inside the sliding column 15. The limit shaft 17 is slidably connected to the outside of the base 16. The adjustment group fixes the rotating tube 12 through the support ring 14. The sliding column 15 slides inside the base 16 to adjust the height of the rotating tube 12 inside the support ring 14 at the top of the sliding column 15. Then, the limit shaft 17 is used for limiting.
[0035] Reference Figures 1 to 3 The protective mechanism 18 includes a support frame 19. The top of the support frame 19 is fixedly connected to the bottom of the spray pipe 5, and the bottom of the support frame 19 is fixedly connected to the top of the trolley 1. The support frame 19 is used to fix and support the spray pipe when no rust removal operation is being performed. A spray head 20 is fixedly connected to the front side of the spray pipe 5. The outer side of the spray head 20 is fixedly connected to the inner side of the protective cover 26. The spray head 20 is located at the front end of the spray pipe 5 and plays the role of sandblasting. The spray head 20 is equipped with multiple nozzles to evenly cover the entire surface. A water storage ring 21 is fixedly connected to the outside of the spray head 20. Multiple water nozzles 22 are fixedly connected to the front side of the water storage ring 21. A splash head 23 is fixedly connected to the front side of the water nozzles 22. The splash head 23 is used to expand the spray range of the water source. The water storage ring 21 is used to store water source and is arranged around the spray head 20 to ensure a sufficient water supply.
[0036] The water nozzle 22 is used to spray the water from the water storage ring 21 onto the working surface. The spraying of the water nozzle 22 and the splash head 23 can effectively suppress the flying of dust and make the dust settle through wetting. A protective cover 26 is fixedly connected to the outside of the water storage ring 21. The protective cover 26 surrounds the spray head 20 and plays a protective role to prevent liquid and debris from splashing onto the operator. The protective cover 26 is made of transparent material so that the operator can clearly observe the work process. It also has a certain degree of corrosion resistance and impact resistance. A water inlet pipe 24 is fixedly connected to the rear side of the water storage ring 21. A water tank 25 is fixedly connected to the bottom of the water inlet pipe 24. The bottom of the water tank 25 is fixedly connected to the top of the trolley 1. The water inlet pipe 24 is responsible for introducing water from the water tank 25 into the water storage ring 21 to ensure the water supply for the spray head 20. The water tank 25 can hold a certain amount of water to ensure that the spray head 20 can work continuously during long-term operation.
[0037] Working principle: Push the trolley 1 to the area to be derusted by the handle 2. After starting, the sand in the storage tank 4 in the debris collection mechanism 3 is sprayed out through the spray pipe 5 and the spray head 20 to carry out sandblasting and rust removal. The spray head 20 is equipped with multiple nozzles, which can evenly cover the entire surface to be derusted. The metal debris and dust generated during the rust removal process are sucked into the suction port 13, rotating pipe 12 and suction pipe 8 by the extraction pump 7 and then into the collection box 6 to be collected, keeping the working area clean. The rotating ball 11 can rotate inside the spherical shell 9 to adjust the suction angle of the suction port 13 and rotating pipe 12. The support ring 14 fixes the rotating pipe 12 inside. The sliding column 15 slides inside the base 16 to adjust the height of the rotating pipe 12 inside the support ring 14 at the top of the sliding column 15. Then, the limiting shaft 17 is used for limiting.
[0038] In the protective mechanism 18, the support frame 19 can fix and support the spray pipe 5 when no rust removal operation is being performed. Water in the water tank 25 flows into the water storage ring 21 through the water inlet pipe 24. The water nozzle 22 and the splash head 23 spray water onto the working surface, effectively suppressing dust and causing dust to settle. At the same time, the protective cover 26 behind the spray head 20 effectively prevents splashes and debris from hitting the operator. The whole process ensures that the rust removal operation is efficient, safe and clean.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
