Description

Technical Field

[0001] This utility model relates to the field of building fire protection technology, specifically a maintenance and upkeep device for building fire protection facilities. Background Technology

[0002] Building fire protection facilities are key equipment for preventing and controlling fires and protecting personal and property safety. Maintenance can ensure their normal operation. Maintenance mainly includes routine inspection, functional testing, and cleaning (cleaning fire protection facilities to remove dust and dirt and prevent blockage and corrosion).

[0003] An existing building fire protection facility maintenance device addresses the issue that smoke detectors, which are often mounted on ceilings, tend to accumulate dust and require timely cleaning. Traditional cleaning methods often result in dust falling directly to the ground or even reaching the height of workers. Furthermore, some maintenance devices are too long or too short, making them inconvenient to store and clean, especially for tall smoke detectors. The current building fire protection facility maintenance device solves these problems. Utility Model Content

A rotating shaft 10 is connected, and a cleaning brush 11 is sleeved on the outer surface of the rotating shaft 10. A second gear 12 is sleeved on the outer surface of the rotating shaft 10 near the bottom. A slot is opened inside the cleaning cover 7, and a retaining plate 13 is engaged inside the slot. One end of the first spring 5 abuts against one side of the push plate 6, and the other end of the first spring 5 abuts against the inner wall of the protective ring 3. A second square groove is opened inside the second support rod 2, and a second support shaft 14 is provided on the inner wall of the second support rod 2. A second spring 15 and a first baffle 16 are sleeved on the outer surface of the second support shaft 14. A first baffle 16 is provided on one side. The hemispherical block 17 and the two ends of the second spring 15 abut against one side of the two first baffles 16 respectively. The protective ring 3 has a first through hole inside, the diameter of which is slightly larger than the diameter of the hemispherical block 17. The first gear 9 meshes with the second gear 12. The bottom wall of the cleaning cover 7 has a groove inside, in which both the first gear 9 and the second gear 12 are located. The outer surface of the cleaning cover 7 is provided with a card box 18, and the inside of the card box 18 is provided with a pull rod 19. The outer surface of the pull rod 19 is welded with a second baffle 20. The inner side wall of the card box 18 is provided with a third support shaft 21. A third spring 22 is fitted onto the outer surface of 21. One end of the third spring 22 abuts against the second baffle 20. A protective cover 23 is provided on the top of the clamping plate 13. A second through hole is opened inside the clamping plate 13. The inner diameter of the second through hole is slightly larger than the diameter of the pull rod 19. A nozzle 24 is clamped onto the inner wall of the cleaning cover 7. Several nozzles 24 are evenly distributed on the inner wall of the cleaning cover 7. A hose 25 is fitted onto one end of the nozzle 24. A connector is fitted onto the other end of the hose 25. A third through hole is opened inside the bottom wall of the protective cover 23. The end of the rotating shaft 10 near the top is clamped into the third through hole.

[0028] To achieve the desired functionality of this building fire protection facility maintenance device, which allows for easy adjustment of the device's length according to ceiling height, cleaning of dust from smoke detector surfaces, collection of swept-down dust, and convenient replacement of the internal cleaning brushes, as shown in the attached document... Figure 1-6As shown, this application adopts the following structure: through the cooperation of the first support rod 1, cleaning cover 7, push plate 6, first support shaft 4, first spring 5, second support rod 2, hemispherical block 17, second spring 15, first baffle 16, protective cover 23, motor 8, first gear 9, second gear 12, rotating shaft 10, cleaning brush 11, hose 25, nozzle 24, pull rod 19, second baffle 20, third spring 22 and clamping plate 13, during use, when cleaning the smoke alarm, the operator holds the first support rod 1, and then adjusts the height of the cleaning cover 7 according to the height of the ceiling and the operator's height. First, push the two push plates 6 inward, so that the two push plates 6 move inward along the first support shaft 4 and squeeze. The first spring 5 and the push plate 6 block one end of the first through hole. Then, the second support rod 2 is pulled upwards until it reaches the required height. Then, the push plate 6 is released, and the first spring 5 releases its elastic force and pushes the push plate 6, so that the push plate 6 no longer blocks the first through hole. Then, the second support rod 2 is pulled again appropriately, or the second support rod 2 is pushed into the first support rod 1, so that the hemispherical block 17 is aligned with the first through hole inside the protective ring 3. Then, the second spring 15 releases its elastic force to push the first baffle 16 and the hemispherical block 17, so that they are locked into the first through hole inside the protective ring 3, fixing the second support rod 2. At the same time, the connector is sleeved on the air compressor bottle connector. Then, the cleaning cover 7 is raised to the ceiling, and the protective cover 23 abuts against the ceiling. The controller starts motor 8, which in turn drives the first gear 9 to rotate. The first gear 9 meshes with the second gear 12, which in turn drives the rotating shaft 10 and the cleaning brushes 11. The rotation of the four cleaning brushes 11 cleans the smoke detector. At the same time, the control valve inside the air compressor bottle is opened and the air speed is adjusted to a suitable level. This allows the air inside the air compressor bottle to be sprayed out through the hose 25 and the nozzle 24, cleaning the dust that is difficult to clean inside the smoke detector. The cleaned dust falls into the cleaning hood 7. When it is time to clean or replace the cleaning brushes 11, the lever 19 is pulled. The lever 19 then moves the second baffle 20 along the third support shaft 21 and compresses the third spring 22 until the lever is pulled. Pull rod 19 is disengaged from the second through hole inside the card plate 13, and then the protective cover 23 is removed. The cleaning brush 11 to be replaced is removed from the outer surface of the rotating shaft 10 and a new cleaning brush 11 is installed. After replacement, the card plate 13 is inserted into the slot inside the cleaning cover 7, and then the pull rod 19 is released. The third spring 22 releases its elasticity and pushes the second baffle 20, so that the pull rod 19 can enter the through hole inside the card plate 13 to limit the protective cover 23. Thus, this building fire protection facility maintenance device has the effects of facilitating the adjustment of the length of the maintenance device according to the height of the ceiling, cleaning the dust on the surface of the smoke alarm, collecting the swept dust, and facilitating the replacement of the cleaning brush inside the maintenance device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
