[0013] Figure 3 This is a structural diagram of a fireproof charging box for a shuttle under fault conditions according to the present invention. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figures 1-3 As shown, a fireproof charging box for a shuttle includes a running track 8, a shuttle 26, and a fireproof charging box 1. A shuttle entrance 16 is provided on one side of the fireproof charging box 1. One end of the running track 8 extends from the shuttle entrance 16 into the fireproof charging box 1. A fireproof gate 14, pulled by a fusible traction unit 15, is installed above the shuttle entrance 16. The fusible traction unit 15 automatically melts after exceeding a certain temperature. When the temperature inside the fireproof charging box 1 exceeds the melting temperature of the fusible traction unit 15, the fusible traction unit 15 automatically melts, and the fireproof gate 14 moves vertically downwards under its own weight, ultimately closing the shuttle entrance 16.

[0016] The travel track 8 is a double-track track, with the fireproof gate 14 located between the two tracks. The two outer sides of the travel track 8 extend vertically upwards to form baffles 4. Several tiny pressure relief holes 20 are provided on the baffles 4. These holes ensure that the pressure inside the fireproof charging box 1 remains the same as atmospheric pressure while preventing open flames or large amounts of smoke from escaping to the outside of the fireproof charging box 1. The upper ends of the two baffles 4 bend outwards to form mounting platforms 19. The two inner sides of the travel track 8 extend vertically upwards to form mounting platforms 19. A mounting plate 24 extends vertically downwards, and a base plate 17 is connected between the two mounting plates 24. A charging pile 12 is installed on the base plate 17. An electrical cabinet box 13 is also provided on the side of the charging pile 12 away from the shuttle car entrance 16. Both the charging pile 12 and the electrical cabinet box 13 are located inside the fireproof charging box 1. When the shuttle car 26 travels along the double track of the travel track 8 into the fireproof charging box 1 and comes into contact with the charging pile 12, the charging interface on the shuttle car 26 automatically connects with the charging pile 12, thereby achieving the purpose of charging the shuttle car 26.

[0017] The fusible traction unit 15 includes a fusible part support 31, with two fusible parts 32 connected to both sides of the fusible part support 31. The upper end of the fireproof gate 14 is connected to the fusible part support 31 through at least two fusible parts 32. The fusible part support 31 is fixed to one side of the fireproof charging box 1, and the fireproof gate 14 and the fireproof front plate 9 are slidably sealed on the side close to each other. The lower contour of the fireproof gate 14 corresponds to the contour of the shuttle car entrance 16. After the fireproof gate 14 is released by the high temperature release part 32, it closes the shuttle car entrance 16. The fusible part 32 is a bismuth-tin alloy. The melting point of the bismuth-tin alloy is about 70°C, and it has good casting performance. At the same time, the bismuth-tin alloy has good chemical stability at room temperature, thereby avoiding changes in the fusible part 32 under non-high temperature conditions due to external factors.

[0018] The fireproof charging box 1 is composed of a lower frame 27, an upper frame 30, a column 3, a baffle 4, and a base plate 17. The lower frame 27 is installed on the mounting platform 19 formed by the upper ends of the two baffles 4. The upper frame 30 is installed above the lower frame 27 via the column. The interior of the fireproof charging box 1 is a fireproof charging compartment 2. Fireproof side plates 11 are sealed on both sides along the length direction between the lower frame 27 and the upper frame 30. A fireproof rear plate 10 is sealed on the side of the lower frame 27 and the upper frame 30 near the rear plate 18 of the charging compartment. A fireproof top plate 23 is sealed in the upper frame 30 of the fireproof charging compartment 2. A fireproof front plate 9 is sealed on the side of the lower frame 27 and the upper frame 30 near the shuttle car entrance 16. A fusible traction unit 15 is installed on the fireproof front plate 9. The fireproof gate 14 is suspended from the lower end of the fusible traction unit 15 by at least two fusible parts 32.

[0019] The lower frame 27 is a "U"-shaped frame spliced ​​together by two long rectangular grooved aluminum profiles and one short rectangular grooved aluminum profile. The gap of the "U"-shaped frame is located above the shuttle car entrance 16, so as to avoid obstructing the release process of the fireproof gate 14. The upper frame 30 is a rectangular frame spliced ​​together by arc-shaped grooved aluminum profiles. The column 3 is an arc-shaped grooved aluminum profile. The two columns 3 near the shuttle car entrance 16 are provided with gate guide grooves. After the fireproof gate 14 is released by the two fusible parts 32, it slides vertically downward along the gate guide groove, and finally closes the shuttle car entrance 16.

[0020] A sensor-operated automatic fire extinguisher 7 is installed on one side of the fireproof roof 23 inside the fireproof charging chamber 2. The sensor-operated automatic fire extinguisher 7 is connected to the external fire extinguishing material tank, and the sensor-operated automatic fire extinguisher 7 can spray fire extinguishing material into the fireproof charging chamber 2 without power control. When the shuttle car 26 enters the fireproof charging chamber 2 along the travel track 8 through the shuttle car entrance 16 and docks with the charging pile 12 for charging, if any one of the shuttle car 26, the charging pile 12, and the electrical cabinet box 13 malfunctions and produces smoke or open flame during the charging process, the temperature in the fireproof charging chamber 2 will rise sharply. When the temperature in the fireproof charging chamber 2 is higher than the sensing temperature of the sensor-operated automatic fire extinguisher, the sensor-operated automatic fire extinguisher releases fire extinguishing material into the fireproof charging chamber 2.

[0021] Based on the fire protection requirements of the working environment of the fireproof charging box 1, hooks 6 are installed on the fireproof top plate 23, and trigger-type fire extinguishers are hung on the hooks 6. When the automatic fire extinguisher 7 releases extinguishing materials into the fireproof charging chamber 2 inside the fireproof charging box 1, the trigger-type fire extinguisher and the automatic fire extinguisher 7 release extinguishing materials into the fireproof charging chamber 2 together, increasing the fire extinguishing efficiency. Alternatively, sound alarms and light alarms can be installed on the outer surface of the fireproof charging box 1 so that warehouse staff can promptly detect accidents inside the fireproof charging box 1 and take timely protective measures to avoid huge losses.

[0022] The working principle of the fireproof charging box for a shuttle vehicle according to this utility model is as follows: When the shuttle vehicle 26 enters the fireproof charging chamber 2 along the travel track 8 through the shuttle vehicle entrance 16 and connects with the charging pile 12 for charging, if any one of the shuttle vehicle 26, the charging pile 12, or the electrical cabinet box 13 malfunctions during the charging process, resulting in smoke or open flame, the temperature in the fireproof charging chamber 2 will rise sharply. When the temperature in the fireproof charging chamber 2 exceeds the melting temperature of the fusible part 32 on the fusible traction unit 15, the fusible part 32 on the fusible traction unit 15 melts and breaks at high temperature, causing the fireproof gate 14 to slide vertically downward along the guide grooves on the two columns 3 until the fireproof gate 14 closes the shuttle vehicle entrance 16. At this time, the fireproof gate 14 makes the fireproof charging chamber 2 sealed relative to the outside world. However, the fireproof charging chamber 2 is not completely sealed from the outside world at this time; it is a mechanism to prevent smoke or open flame from the fireproof charging chamber 2 from overflowing into the fireproof charging box 1. While the fireproof charging chamber 2 is external, there are still gaps to release the pressure inside. In this embodiment, these gaps are several tiny pressure relief holes 20 opened on the baffle 4. These pressure relief holes 20 can ensure that the pressure inside the fireproof charging chamber 2 is always the same as atmospheric pressure, while preventing open flames or large amounts of smoke inside the fireproof charging chamber 2 from overflowing to the outside of the fireproof charging box 1. This not only prevents damage to the automated warehouse in the event of a fire or explosion of the shuttle car 26 or the electrical box 12 in the fireproof charging chamber 2, but also prevents damage to the fireproof charging box 1 caused by excessive pressure inside the fireproof charging chamber 2. When the temperature inside the fireproof charging chamber 2 is higher than the sensing temperature of the induction automatic fire extinguisher, the induction automatic fire extinguisher releases extinguishing material into the fireproof charging chamber 2. During this process, the pressure relief holes 20 on the baffle 4 ensure that the pressure inside the fireproof charging chamber 2 is always the same as atmospheric pressure, thereby preventing the fireproof charging box 1 from expanding outward and breaking due to excessive pressure inside the fireproof charging chamber 2, or even from exploding.

[0023] The above are the preferred embodiments described in this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
