[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0029] like Figures 1 to 4As shown, a waterproof shell for a car fire-fighting robot according to one embodiment of this utility model includes a shell body 1, with a top cover plate 11 covering the shell body 1. The top cover plate 11 has a third through hole 1101. Specifically, the fire-fighting robot is equipped with a water spray pipe that matches the third through hole 1101. During operation, the water spray pipe can extend from the third through hole 1101 to spray water for fire extinguishing. All of the above are prior art and will not be described in detail.
[0030] In order to seal the car fire-fighting robot, a waterproof component is provided inside the outer shell 1. The waterproof component includes a waterproof plate 12, which is installed inside the outer shell 1. A first water storage space is formed between the waterproof plate 12 and the upper cover plate 11. A fourth through hole 1201 matching the third through hole 1101 is opened on the waterproof plate 12. A first sealing ring 123 is installed on the hole wall of the fourth through hole 1201.
[0031] Specifically, during fire extinguishing, the water sprayed from the sprinkler pipe will drip onto the upper cover plate 11. This water will flow into the first water storage space from the third through hole 1101. The first sealing ring 123 seals the fourth through hole 1201 and the sprinkler pipe to prevent water droplets in the first water storage space from falling onto the battery and circuit inside the outer casing 1, thus protecting the battery and circuit.
[0032] In addition, because the first water storage space is filled with water, this water protects the first sealing ring 123, preventing the first sealing ring 123 from melting due to high temperature, thus ensuring the operation capability of the car fire-fighting robot.
[0033] Furthermore, the upper cover plate 11 is provided with bolts 111, and the upper cover plate 11 is threadedly connected to the outer shell body 1 by the bolts 111. Since the power supply battery and water spray pipes inside the car fire-fighting robot require maintenance, the upper cover plate 11 and waterproof plate 12 can be removed to perform maintenance on the car fire-fighting robot.
[0034] It is worth noting that due to the high temperatures at fire scenes, the internal circuitry of the car-based firefighting robot may spontaneously combust under the influence of high temperatures during prolonged operation. Therefore, to ensure the car-based firefighting robot can be sealed and cooled down, such as... Figures 3 to 7 As shown, the waterproof assembly also includes a fixing frame 13, which is integrally formed on the lower plate of the outer shell body 1. The fixing frame 13 has a slot 131, and the waterproof plate 12 has an integrally formed sealing plate 122 that matches the slot 131. After the sealing plate 122 is inserted into the slot 131, a second water storage space is formed between the fixing frame 13 and the outer shell body 1.
[0035] Specifically, there is a gap between the waterproof plate 12 and the inner wall of the outer shell 1. Water in the first water storage space flows into the second water storage space through the gap between the waterproof plate 12 and the outer shell 1, so that the water in the second water storage space can insulate some of the heat and prevent the temperature inside the outer shell 1 from getting too high, thus protecting the circuit and battery inside the outer shell 1.
[0036] Furthermore, the sealing plate 122 is wrapped with a rubber layer to achieve a better seal for the second water storage space and prevent water in the second space from entering the slot 131, thereby causing damage to the battery and circuit inside the outer casing 1.
[0037] Furthermore, the outer shell 1 has a first through hole 101, which is connected to the second water storage space. Specifically, water in the second water storage space can drain out through the first through hole 101, allowing water flow and further reducing the temperature inside the outer shell 1. When water in the second water storage space flows out through the first through hole 101, water in the first water storage space flows into the second water storage space, also allowing water flow in the first water storage space. This prevents the water in both the first and second water storage spaces from boiling over and causing the temperature inside the outer shell 1 to become too high when the fire truck robot operates at a fire scene for an extended period.
[0038] It is worth noting that although the first and second water storage spaces can block heat from the fire scene, the batteries and circuits inside the car fire-fighting robot also generate heat when they are working. If this heat cannot be dissipated for a long time, it will also damage the car fire-fighting robot and affect its service life.
[0039] To solve the above problems, fins 121 are welded to the panel of the waterproof plate 12, and a drain outlet 1202 connected to the fins 121 is provided on the waterproof plate 12. Water in the first water storage space enters the fins 121 through the drain outlet 1202, exchanges heat with the air inside the outer shell body 1, and reduces the temperature inside the outer shell body 1.
[0040] Furthermore, the fin 121 has an internal thread 1211, which is connected to a drain pipe 14. The drain pipe 14 has an external thread 141. The outer shell body 1 has a second through hole 102, and the end of the drain pipe 14 away from the fin 121 passes through the second through hole 102. The fin 121 is located between the opposite side walls of the fixing frame 13. The fixing frame 13 has a sixth through hole 1301 that matches the drain pipe 14, and the sealing plate 122 has a fifth through hole 1221 that matches the sixth through hole 1301. A second sealing ring 132 is installed on the sixth through hole 1301.
[0041] Specifically, the second sealing ring 132 seals the sixth through hole 1301 and the drain pipe 14, preventing water from flowing in. Water inside the fin 121 is discharged from the external thread 141, allowing water circulation within the fin 121 and achieving a better cooling effect. Because the second sealing ring 132 is immersed in the water in the second water storage space, the water in the second water storage space can protect the second sealing ring 132.
[0042] Furthermore, when the drain pipe 14 is threaded into the internal thread 1211, it can also fix the fins 121, thereby fixing the waterproof membrane 12 within the outer casing 1. Further, a tensioning block 142 is integrally formed on the drain pipe 14. When maintaining the circuitry within the outer casing 1, a wrench can be used to hold the tensioning block 142, facilitating the disassembly of the drain pipe 14 and allowing the removal of the waterproof membrane 12 from the outer casing 1.
[0043] It is particularly important to note that the overall velocity of the water flowing out of the drain pipe 14 and the first through hole 101 should be less than the velocity of the water flowing into the first water storage space. This ensures that the first water storage space, the second water storage space, and the fins 121 remain full of water, thus guaranteeing the protection of the car fire-fighting robot.
[0044] Furthermore, a handle 124 is welded to the top plate of the waterproof membrane 12, with the end of the handle 124 away from the waterproof membrane 12 fitting against the top cover plate 11. The handle 124 facilitates the removal of the waterproof membrane 12 from the outer shell 1, while also providing support and reinforcement for the top cover plate 11 to prevent damage to the top cover plate 11 from collapsing debris at the fire scene.
[0045] In use, the car-mounted firefighting robot enters the fire scene. Water sprayed from the robot's nozzles flows into the first water storage space through the third through-hole 1101. The water in the first water storage space protects the first sealing ring 123, preventing it from melting due to high temperatures and ensuring its sealing effect. The water in the first water storage space enters the second water storage space and the fins 121, and is discharged through the drain pipe 14 and the first through-hole 101, allowing water to flow. This not only provides waterproofing but also cools the car-mounted firefighting robot.
