DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] like Figure 1-Figure 12 As shown, a waterproof fire extinguishing distribution box proposed in one embodiment of the present application includes a distribution box body 1 and a plurality of air inlet holes 2 and air outlet holes 3 arranged on the outer side thereof, as shown in FIG. Figure 5 As shown, the air outlet 3 is located at the top of the distribution box body 1, the air inlet 2 is located at the bottom of the distribution box body 1, a mounting plate 31 for mounting electrical equipment is vertically arranged in the distribution box body 1, and a threading hole 32 for passing a wire is provided on the distribution box body 1, and further includes:

[0036] The collecting box 4 is in the shape of a plate and is arranged on the inner wall of the distribution box body 1. The top of the collecting box 4 has an opening 5. A plate body 6 is arranged in the collecting box 4. There is a gap between the bottom of the plate body 6 and the two opposite sides thereof and the inner wall of the collecting box 4. The plate body 6 is filled with MOF-303. MOF-303 is a metal organic framework material. The working principle is based on its porous structure. It has a large specific surface area and excellent adsorption performance. It can absorb moisture in the air and release the moisture after slightly heating. A vent hole 7 is opened on the top of the plate body 6. A junction block 8 is arranged in the distribution box body 1, and covers a plurality of air inlet holes 2. The plate body 6 is connected to the junction block 8 through a hose 9. When the distribution box body 1 is working, the hot air in it floats up and passes through The air is discharged through the air outlet 3. At this time, the outside air can pass through the air inlet 2, the confluence block 8, the hose 9, the plate body 6 and the collecting box 4 in sequence, and enter the distribution box body 1 for heat dissipation. In this process, the MOF-303 can absorb the moisture in the air to prevent the moisture from entering the inside of the distribution box body 1. According to the actual situation, it can be selected whether to install an exhaust fan mechanism 33 covering multiple air outlets 3 on the top of the distribution box body 1 to improve the exhaust efficiency. A heating strip 10 is installed at the bottom of the plate body 6. When the heating strip 10 is energized, the plate body 6 and the MOF-303 inside it can be heated, and then the moisture in the MOF-303 is released to form water vapor. A water tank 11 is provided on the top of the collecting box 4. The water The water tank 11 and the collection box 4 are both made of aluminum alloy with high thermal conductivity. The water tank 11 is used to store water. The surface temperature is relatively low under normal conditions. The water tank 11 has a condensation portion 12. When water vapor is discharged from the plate body 6 through the air vents 7, it can float up and contact the water tank 11, and condense into liquid water on the condensation portion 12. Then, water droplets slide from the condensation portion 12 to the inner wall of the collection box 4, and drip to the bottom of the collection box 4 under the action of gravity to collect water. The bottom end of the water tank 11 has a water outlet 13, and is hinged with a cover plate 14. A trigger wire 15 is connected to the distribution box body 1. The trigger wire 15 is made of low-density polyethylene, which will melt at 90 to 120 degrees. In actual use, multiple wires can be set. The trigger wire 15 is used to improve its tensile strength. A lifting ring is provided on one side of the air outlet 3. The trigger wire 15 passes through the lifting ring, and one end of the trigger wire 15 is connected to the cover plate 14. The trigger wire 15 is connected to the movable end of the cover plate 14. It should be specifically explained here that at a temperature below the boiling point, water can also slowly evaporate into water vapor, that is, the water vapor released by the heating strip 10 cannot reach the temperature of melting the trigger wire 15. When a short circuit occurs inside the distribution box and a fire occurs, the hot air generated floats up and contacts the trigger wire 15 at the air outlet 3 and melts the trigger wire 15. In this way, it can be detected whether there is a fire in the distribution box. Then the cover plate 14 can be opened under the water pressure, and the water in the water tank 11 can be discharged from the water outlet 13 into the collection box 4.

[0037] The gas outlet pipe 16 is arranged in the distribution box body 1. The distribution box body 1 is equipped with a gas cylinder 17. The gas cylinder 17 is filled with compressed carbon dioxide. The output end of the gas cylinder 17 is connected to the gas outlet pipe 16 through a blocking mechanism 18. The blocking mechanism 18 can prevent the gas in the gas cylinder 17 from entering the gas outlet pipe 16. When the blocking mechanism 18 is activated, the gas cylinder 17 can be connected to the gas outlet pipe 16, and the compressed carbon dioxide can enter the distribution box body 1 to extinguish the flame in the distribution box.

[0038] The box body 19 is plate-shaped and installed on the distribution box body 1. It is located on the back side of the distribution box body 1. The air inlet 2 is located below the box body 19. A water inlet 20 is constructed on the box body 19 and is connected to the collection box 4. The top of the box body 19 is connected to the bottom of the collection box 4 through the water inlet 20, so that the water collected by the collection box 4 can enter the box body 19 from the water inlet 20. A driving part 21 floats in the box body 19 and cooperates with the blocking mechanism 18. A accommodating box 22 is provided at the bottom of the distribution box body 1, and is connected to the box body 19 through a solenoid valve 23. The solenoid valve 23 is electrically connected to the heating strip 10. The solenoid valve 23 and the heating strip 10 are connected in series in the circuit. The working principle here is as follows: Fig.12 As shown, when the heating strip 10 is powered, the solenoid valve 23 is opened, and when the condensed water enters the box 19, the water level in the box 19 cannot exceed the solenoid valve 23. When the fire trigger wire 15 inside the distribution box is disconnected, the water in the water tank 11 enters the box 19. Since the solenoid valve 23 is in a closed state, the water level in the water tank 11 rises, the driving part 21 can float upward, and drive the blocking mechanism 18 to operate, so as to connect the gas storage bottle 17 with the gas outlet pipe 16. The water tank 11 is provided with a moisture absorption component 24, and the moisture absorption component 24 can transport the water in the receiving box 22 to the water tank 11, so that the collected condensed water can be used;

[0039] The present application can introduce outside air into the plate body 6 through the cooperation of the confluence block 8 and the hose 9 when the distribution box dissipates heat, and absorb moisture in the air through the MOF-303 filled therein. After a period of use, the plate body 6 and the MOF-303 therein can be heated by the heating strip 10 to release the absorbed moisture. When the water vapor contacts the condensation part 12 of the water tank 11, it can condense and enter the box body 19 through the collection box 4. By repeating the above operation, the moisture entering the inside of the distribution box can be reduced to achieve the purpose of waterproofing. At the same time, the water that overflows the solenoid valve 23 can enter the receiving box 22 and accumulate in the water tank 11 through the moisture absorption component 24. When a fire occurs inside the distribution box, the high-temperature gas melts and triggers Thread 15, cover 14 is opened, water enters box body 19 through collecting box 4, at this time, solenoid valve 23 is in closed state, water level in box body 19 rises, and drives plugging mechanism 18 to operate through floating driving part 21, so as to connect gas cylinder 17 with gas outlet pipe 16, so as to extinguish fire in distribution box. The present application combines waterproof structure with fire extinguishing structure by adopting such design, and can collect moisture in air while reducing moisture in air entering distribution box, and utilizes collected water in case of fire, so as to drive driving part 21 to float, and forces plugging mechanism 18 to operate, so as to connect gas cylinder 17 with gas outlet pipe 16, so as to extinguish fire. Compared with the prior art, the present application has strong structural linkage and is convenient to use.

[0040] like Figure 3 , Figure 4 and Fig.10 As shown, in some embodiments, the condensation portion 12 includes inclined surfaces 1201 symmetrically constructed on both sides of the water outlet 13, the spacing between the two inclined surfaces 1201 gradually decreases from top to bottom, and V-shaped grooves 1202 are provided on the inclined surfaces 1201. The edges on both sides of the V-shaped grooves 1202 are in contact with the inner walls on both sides of the collection box 4 respectively. When water vapor rises, it can contact the V-shaped grooves 1202 and move toward both sides of the water tank 11 along the inclined direction of the inclined surfaces 1201, and metal wires 1203 are evenly distributed in the V-shaped grooves 1202. Such a design can increase the contact area between the condensation bag and water vapor, thereby improving its condensation effect, and as shown in FIG. Figure 3 As shown, the top of the plate body 6 is conical, and the air holes 7 are arranged thereon. When the condensed water falls thereon, it can slide along the plate body 6 and is not easy to enter the plate body 6 through the air holes 7.

[0041] like Figure 2 , Figure 3 and Figure 5As shown, in some embodiments, there are two collecting boxes 4, which are symmetrically arranged on the inner wall of the distribution box body 1 and are respectively connected to the two sides of the box body 19. The box body 19 is symmetrically constructed with partitions 25, which extend from the top surface of the box body 19 toward the bottom surface thereof. The driving part 21 is separated from the two water inlets 20 by the two partitions 25. It should be specifically noted that both ends of the trigger wire 15 are passed through hanging rings and are respectively connected to the movable ends of the two water tanks 11. Such a design, on the one hand, can improve the water collection effect by increasing the number of collecting boxes 4 and the plates 6 therein. On the other hand, when the trigger wire 15 is disconnected, when the water in the two water tanks 11 enters the water inlet 20, the water surface can be impacted under the height difference. Under the action of the liquid pressure, the liquid levels on the opposite sides of the two partitions 25 can be forced to rise rapidly in an instant, and the driving part 21 can be driven to float. Then, when the water stops entering, the liquid level in the water tank 11 can be horizontal under the action of atmospheric pressure.

[0042] like Figure 1 and Fig.11 As shown, in some embodiments, the moisture absorption component 24 includes a flow channel 2401 arranged on the opposite side of the distribution box body 1, the flow channel 2401 is arranged vertically, the receiving box 22 and the water tank 11 are connected through the flow channel 2401, and a curved portion 2402 is constructed on the flow channel 2401, and water can be stored at the curved portion 2402. The flow channel 2401 is filled with a moisture absorption cotton strip 2403, and the two ends of the moisture absorption cotton strip 2403 are respectively inserted into the receiving box 22 and the water tank 11. Here, the capillary phenomenon is used to absorb the water in the receiving box 22 to the cotton strip. The water will rise along the absorbent cotton strip 2403 until the upward pulling force is balanced with the gravity of the liquid column. Since the absorbent cotton strip 2403 has a limited moisture absorption height, the applicant constructs a curved portion 2402 for storing water on the flow channel 2401. After the absorbent cotton strip 2403 absorbs water, the inner surface of the curved portion 2402 is wetted and water can be stored therein. Subsequently, the water in the curved portion 2402 can be transported to the water tank 11 through the absorbent cotton strip 2403 to increase the moisture absorption height of the absorbent cotton strip 2403.

[0043] like Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments, the blocking mechanism 18 includes a tube body 1801 vertically arranged on the top of the box body 19, the output end of the gas storage bottle 17 and the inlet end of the gas outlet pipe 16 are connected to the tube body 1801, and the two are vertically connected to the tube body 1801 in an up-down staggered state, and a piston rod 1802 is slidably fitted in the tube body 1801, as shown in FIG. Figure 6As shown, the sliding direction of the piston column 1802 is perpendicular to the output direction of the output end of the gas cylinder 17. The side of the piston column 1802 can block the output end of the gas cylinder 17. A connecting rod 1803 is coaxially connected to the piston column 1802. The end of the connecting rod 1803 passes through the box body 19 and is connected to the driving part 21. When the driving part 21 floats up, the piston column 1802 can be driven to slide upward. At this time, the gas sprayed from the gas cylinder 17 can enter the outlet pipe 16 through the distance between the inner wall of the tube body 1801 and the connecting rod 1803.

[0044] like Figure 5-Figure 7 As shown, in some embodiments, the driving unit 21 includes a sleeve 2101 symmetrically arranged in the box body 19, the sleeve 2101 is vertically connected to the top surface of the box body 19, and a movable rod 2102 is slidably fitted in the sleeve 2101, and the movable rod 2102 is connected to the sleeve 2101 through a tension spring 2103, and the tension spring 2103 is used to provide a pulling force to pull the movable rod 2102 upward, and the two movable rods 2102 are connected through a buoyancy plate 2104, the buoyancy plate 2104 is foam, and the connecting rod 1803 is connected to the top of the buoyancy plate 2104, and two first magnets 2105 are installed in the box body 19, and the ends of the two movable rods 2102 are magnetically connected to the two first magnets 2105 respectively, and the ends of the movable rods 2102 are installed with iron sheets 34, as shown in FIG. Figure 7 As shown, when the movable rod 2102 is in an extended state, the first magnet 2105 can adsorb the end of the movable rod 2102. When the heating strip 10 is energized, the solenoid valve 23 is opened. When the condensed water enters the box 19, the water level in the box 19 cannot exceed the solenoid valve 23. Under the adsorption of the first magnet 2105, the movable rod 2102 cannot be lifted. When the fire trigger wire 15 inside the distribution box is disconnected, water enters the water tank 11. Since the solenoid valve 23 is in a closed state, the water level in the box 19 rises, the buoyancy of the buoyancy plate 2104 increases, and the sum of the tension of the tension spring 2103 and the buoyancy of the buoyancy plate 2104 is greater than the magnetic force of the first magnet 2105. At this time, the movable rod 2102 is separated from the first magnet 2105, and the movable rod 2102 drives the buoyancy plate 2104 to be quickly lifted under the action of the tension spring 2103, and drives the piston column 1802 to move through the connecting rod 1803.

[0045] like Figure 8 and Fig. 9As shown, in some embodiments, a first baffle 26 is slidably fitted in the distribution box body 1, and the first baffle 26 is slidably installed in a vertical shape and fits with the inner wall of the distribution box body 1. The junction block 8 is installed on the first baffle 26. When the first baffle 26 slides, the junction block 8 can be staggered with the air inlet 2 to close the air inlet 2. A second baffle 27 is hinged on the inner wall of the distribution box body 1, and the second baffle 27 is located on one side of the air outlet 3. The second baffle 27 is connected to the distribution box body 1 through a torsion spring 28. The movable end of the torsion spring 28 is fixed to the second baffle 27, and the fixed end of the torsion spring 28 is connected to the distribution box body 1. Under the action of the torsion spring 28, the second baffle 27 can Rotate along the hinge point and close the air outlet 3. A trigger member 29 is movably provided at the output end of the air outlet pipe 16. The first baffle 26 and the second baffle 27 are both linked with the trigger member 29, that is, the first baffle 26 and the second baffle 27 are fixed by the trigger member 29. When the gas storage cylinder 17 is connected with the air outlet pipe 16 and the air outlet pipe 16 sprays gas, the trigger member 29 can be triggered. At this time, the trigger member 29 releases the restriction on the first baffle 26 and the second baffle 27, and the first baffle 26 slides, and the second baffle 27 can rotate along the hinge point to close the air inlet 2 and the air outlet 3, thereby reducing the entry of external oxygen and facilitating the purpose of rapid fire extinguishing.

After driving the second baffle 27 to rotate along the hinge point, the first baffle 26 can be slid up to limit the movement of the second baffle 27 through the limit plate 2905. Subsequently, the cross plate 2901 can be adsorbed by the second magnet 2903 to fix the first baffle 26 and the second baffle 27. When the gas enters the air outlet pipe 16 and is sprayed out from the nozzle 2902, the cross plate 2901 can slide downward under the action of the gas and separate from the second magnet 2903. At this time, the first baffle 26 can release the restriction on the second baffle 27, thereby closing the air inlet 2 and the air outlet 3.
