Description

Technical Field

[0001] This utility model relates to the field of early warning devices, and in particular to an integrated early warning device. Background Technology

[0002] A smoke detector is a device used to detect smoke, typically for fire prevention. It works by monitoring smoke particles in the air; once a certain concentration of smoke is detected, it emits a loud alarm to alert people to a potential fire hazard, allowing them to take timely measures to prevent a fire or minimize damage.

[0003] Utility model disclosure CN218768342U discloses an integrated early warning device, including an early warning device body. The early warning device body includes a fixed base, on which a fixed cover is mounted. The fixed cover has an internal cavity, and a rotating seat is movably mounted inside the cavity. Rollers are fixed to the sides of the rotating seat, and a rubber layer is fixed to the rollers. A filter screen is installed on the inner wall of the cavity, and the rubber layer contacts and cooperates with the inner wall of the filter screen. The rotating seat has a mounting hole, and a monitoring mechanism is movably mounted inside the mounting hole. In this integrated early warning device, as the rotating seat rotates, the rubber layer on the roller surface scrapes against the filter screen, concentrating and removing dust adhering to the inner wall of the filter screen without affecting the normal operation of the device.

[0004] When the aforementioned warning device is in use, the rollers briefly reciprocate on the inner wall of the filter screen. The reciprocating movement of the rotating seat causes the rubber layer on the surface of the rollers to scrape against the filter screen. This scraping removes the dust adhering to the inner wall of the filter screen. Although the rollers can play a certain cleaning role, the installation of multiple rollers affects ventilation and compresses the ventilation space. Furthermore, after the dust is scraped by the rollers, it still floats in the cavity. After falling, some dust still adheres to the filter screen. For integrated warning devices installed at low locations, this cleaning method has certain drawbacks.

[0005] Therefore, it is necessary to provide a new integrated early warning device to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an integrated early warning device.

[0007] The integrated early warning device provided by this utility model includes a base and a protective device. A ring-shaped protective cover is fixedly installed on the base.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figures 1-6 ,in, Figure 1 A schematic diagram of the integrated early warning device provided by this utility model; Figure 2 for Figure 1 The diagram shows a decomposed structural representation of the structure. Figure 3 for Figure 1 The diagram shows the structure of the movable plate and the first spring. Figure 4 for Figure 2 A cross-sectional structural schematic diagram of the side plate shown; Figure 5 for Figure 2 A cross-sectional structural diagram of the mounting column shown; Figure 6 for Figure 2 The diagram shows the structure inside the protective cover.

[0027] In the specific implementation process, such as Figures 1-6As shown, the device includes a base 1 and a protective device. The bottom of the base 1 has multiple holes for wires to pass through. A ring-shaped protective cover 2 is fixedly installed on the base 1. A mounting post 3 is fixedly installed on the top of the base 1 inside the protective cover 2. A monitoring mechanism 26, which is a fisheye camera, is installed on the mounting post 3. The protective cover 2 has a receiving groove 4. Multiple equidistant first ventilation holes 5 are formed on the inner wall of the receiving groove 4, and multiple equidistant second ventilation holes 6 are formed on the outer wall of the receiving groove 4. The protective device includes a top ring 7, an outer cover 8, and an inner cover 9. The outer cover 8 and the inner cover 9 are both fixed to the bottom of the top ring 7. Multiple second filters 10 are fixedly installed on the outer cover 8. Multiple first filter screens 11 are fixedly installed on the cover 9. The bottom of the outer cover 8 is fixed with a connecting device connected to the base 1. By rotating the outer cover 8 and the inner cover 9, ventilation or closure of multiple second vent holes 6 and multiple first vent holes 5 can be achieved. Multiple first vent holes 5 face multiple first filter screens 11, and multiple second vent holes 6 face multiple second filter screens 10, which facilitates heat dissipation and gas flow. When the device is not in use, the top ring 7 can be rotated so that multiple non-second filter screens 10 on the outer cover 8 face the second vent holes 6, and multiple non-first filter screens 11 on the inner cover 9 face the first vent holes 5, thereby making it difficult for dust from the outside to enter the receiving groove 4.

[0028] The connecting device includes a fixing ring 12 and two side plates 13. The fixing ring 12 is fixed to the bottom of the outer cover 8, and the two side plates 13 are respectively fixed to both sides of the fixing ring 12. A placement groove 14 is provided on the base 1. Two insertion holes 15 for the two side plates 13 to be moved into the top of the placement groove 14 are provided. A pressing component is also installed on the inner wall of the placement groove 14. The pressing component includes a movable plate 16 and a plurality of first springs 17. The movable plate 16 is slidably disposed in the placement groove 14, and the plurality of first springs 17 are respectively fixed to the placement groove 14. The bottom wall has a groove, and the tops of multiple first springs 17 are fixedly connected to the movable plate 16, so that the outer cover 8 is located outside the protective cover 2 and the inner cover 9 is located inside the protective cover 2. The two side plates 13 are respectively moved down to correspond to the two insertion ports 15. The fixing ring 12 and the side plates 13 press the movable plate 16, and the first springs 17 are compressed, so that the bottom of the movable plate 16 is attached to the bottom wall of the placement groove 14. Rotating the top ring 7 causes the outer cover 8 and the inner cover 9 to rotate, which facilitates the installation of the outer cover 8 and the inner cover 9.

[0029] Elastic elements are installed in the grooves at the bottom of both side plates 13. The movable plate 16 has two first positioning grooves 18 and two second positioning grooves 19. When the ends of the two elastic elements move into the first positioning grooves 18, the second filter screen 10 and the first filter screen 11 are respectively aligned with the second vent 6 and the first vent 5. When the ends of the two elastic elements move into the second positioning grooves 19, the outer cover 8 and the inner cover 9 respectively close the second vent 6 and the first vent 5. The elastic elements include a second spring 20 and a positioning post 21. The positioning post 21 is slidably disposed in the groove at the bottom of the side plate 13, and the end of the positioning post 21 is hemispherical. The structure is as follows: the two ends of the second spring 20 are fixed to the bottom wall of the groove at the bottom of the side plate 13 and the positioning post 21, respectively. The positioning post 21 moves into the groove of the side plate 13 due to compression. The end of the positioning post 21 moves into the first positioning groove 18. At this time, multiple first vent holes 5 are facing multiple first filter screens 11, multiple second vent holes 6 are facing multiple second filter screens 10, and the end of the positioning post 21 moves into the second positioning groove 19, so that multiple non-second filter screens 10 on the outer cover 8 are facing the second vent holes 6, and multiple non-first filter screens 11 on the inner cover 9 are facing the first vent holes 5, which facilitates the positioning work when the top ring 7 moves.

[0030] The top of the mounting column 3 has a movable groove 22, and a third spring 23 is fixed inside the movable groove 22. The end of the third spring 23 is fixedly connected to the monitoring mechanism 26.

[0031] The inner walls of the accommodating tank 4 are respectively equipped with a detection mechanism 24 and an alarm mechanism 25. The alarm mechanism 25 is a sound generator, and the detection mechanism 24 is a smoke sensor.

[0032] Working principle: The top ring 7 is moved down, so that the outer cover 8 is located outside the protective cover 2 and the inner cover 9 is located inside the protective cover 2. The two side plates 13 are moved down corresponding to the two insertion ports 15. The fixing ring 12 and the side plates 13 press the movable plate 16, and the first spring 17 is compressed, so that the bottom of the movable plate 16 is in contact with the bottom wall of the placement groove 14. The positioning pin 21 moves into the groove of the side plate 13 due to compression. The top ring 7 is rotated, so that the outer cover 8 and the inner cover 9 are rotated. The side plate 13 moves on the movable plate 16 and is in contact with the top wall of the inner cavity of the placement groove 14. The positioning pin 21 moves on the movable plate 16. When the two positioning pins 21 move to the two first springs 15 respectively, the positioning pin 21 moves down. After the positioning groove 18 is in position, under the action of the compressed second spring 20, the end of the positioning post 21 moves into the first positioning groove 18. At this time, multiple first vent holes 5 are facing multiple first filter screens 11, and multiple second vent holes 6 are facing multiple second filter screens 10, which facilitates heat dissipation and gas flow. When the device is not in use, the top ring 7 can be rotated, and the end of the positioning post 21 moves into the second positioning groove 19, so that multiple non-second filter screens 10 on the outer cover 8 are facing the second vent holes 6, and multiple non-first filter screens 11 on the inner cover 9 are facing the first vent holes 5, thereby making it difficult for external dust to enter the receiving groove 4.
