DETAILED DESCRIPTION
[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Please see Figures 1-5 This utility model provides a technical solution: an emergency lighting centralized power supply device, comprising: a protective shell 1, with support plates 2 fixedly installed on both the left and right sides of the lower end of the protective shell 1, the support plates 2 lifting the protective shell 1 off the ground, a flame-retardant plate 5 fixedly installed on the inner side of the protective shell 1, the flame-retardant plate 5 preventing the spread of fire, a base plate 9 fixedly installed at the bottom end of the protective shell 1, the base plate 9 maintaining a certain distance from the ground when the support plates 2 lift the protective shell 1 off the ground, and a placement plate 6 fixedly installed at the inner end of the protective shell 1, the placement plate 6 having several evenly spaced circular holes 7, the placement plate 6 supporting a lead-acid battery 15, and when the lead-acid battery 15 leaks, the leaked sulfuric acid liquid can flow through the circular holes 7 to the upper end of the base plate 9.
[0024] The protective shell 1 is equipped with a heat dissipation component located inside the flame-retardant plate 5. The heat dissipation component includes through holes 10 and heat dissipation channels 11. Several through holes 10 are provided and are evenly distributed on the four sides of the outer end of the base plate 9. An air duct 13 is fixedly installed at the upper end of each through hole 10. The upper end of the air duct 13 is fixedly installed at the lower end of the placement plate 6. The air duct 13 also serves to support the placement plate 6. Several heat dissipation channels 11 are provided and are evenly fixedly installed on the inner walls of the four ends of the flame-retardant plate 5. The lower end of each heat dissipation channel 11 passes through the placement plate 6 and is connected and communicated with the upper end of the air duct 13. A heat dissipation fin 12 is fixedly installed on the side wall of each heat dissipation channel 11. Half of the heat dissipation fin 12 is located inside the heat dissipation channel 11 and the other half is located outside the heat dissipation channel 11. Since the support plate 2 lifts the base plate 9, air will enter the air duct 13 through the through holes 10 and then flow into the heat dissipation channel 11, carrying away the heat on the heat dissipation channel 11 and the heat dissipation fin 12.
[0025] The lower end of the lead-acid battery 15 is located at the upper end of the placement plate 6. The four outer walls of the lead-acid battery 15 are in contact with the outer end of the heat sink 12. The heat sink 12 can quickly remove the heat generated by the lead-acid battery 15, thereby improving the heat dissipation efficiency of the lead-acid battery 15.
[0026] A lead-acid battery 15 is placed on the upper end of the placement plate 6. Wires 17 are connected to the two terminals 16 at the upper end of the lead-acid battery 15. An electric wiring switch 18 is installed on the wires 17. A controller 3 is fixedly installed on the outer wall of one end of the protective shell 1, and an alarm 4 is fixedly installed on the outer wall of the other end. The controller 3 is electrically connected to the alarm 4, the carbon dioxide detection sensor 8, and the electric wiring switch 18.
[0027] A leakage detection component is installed between the base plate 9 and the placement plate 6. The leakage detection component includes a carbon dioxide detection sensor 8 and limestone powder 14. The carbon dioxide detection sensor 8 is fixedly installed at the lower end of the placement plate 6, and the limestone powder 14 is laid on the upper end of the base plate 9. The sulfuric acid solution flowing into the base plate 9 reacts with the limestone powder 14 to produce carbon dioxide gas. When the carbon dioxide reaches a certain concentration, the carbon dioxide detection sensor 8 detects the carbon dioxide and sends a signal to the controller 3. The controller 3 sends a signal to the electric wiring switch 18, which disconnects the wire 17, thereby preventing the lead-acid battery from continuously supplying power in the event of leakage and minimizing the lead-acid battery failure. At the same time, the controller 3 controls the alarm 4 to sound an alarm and notify the staff.
[0028] In actual use, when lead-acid battery 15 leaks, sulfuric acid flows into base plate 9 and reacts with limestone powder 14 to produce carbon dioxide gas. When the carbon dioxide reaches a certain concentration, carbon dioxide detection sensor 8 detects the carbon dioxide and sends a signal to controller 3. Controller 3 sends a signal to electric wiring switch 18, which disconnects wire 17, thereby preventing the lead-acid battery from continuously supplying power in the event of leakage and minimizing lead-acid battery failure. At the same time, controller 3 controls alarm 4 to sound an alarm and notify staff.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
