DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1-10As shown, an embodiment of the present invention discloses an assembled municipal traffic tunnel escape device, comprising a plurality of escape pipes 1 connected end to end, two adjacent escape pipes 1 being connected by a docking mechanism 2, a plurality of reinforcing members 3 adapted thereto being clamped on the outer surface of the escape pipe 1, and the reinforcing members 3 being fixed to the top wall of the tunnel by expansion bolts, an escape opening being provided at the bottom of the escape pipe 1, an escape door 4 being hingedly connected inside the escape opening, a mounting block 5 being fixedly connected inside the escape pipe 1, a hinged seat 6 being fixedly connected at the bottom of the mounting block 5, and the hinged seat 6 being located above the escape opening, an escape ladder 13 being rotatably connected inside the hinged seat 6, a connecting pipe 14 being fixedly connected at the bottom of the escape pipe 1, and the connecting pipe 14 being located on the right side of the escape opening, and the connecting pipe A water collecting pipe 9 is arranged directly below 14, and the water collecting pipe 9 is abutted against the connecting pipe 14 and fixedly connected by a first flange. The length of the escape pipe 1 is preferably 8-10 meters, the inner diameter of the escape pipe 1 is preferably 80-100 cm, and the distance between the bottom end of the water collecting pipe 9 and the ground is preferably 0.5-0.8 m. By arranging the reinforcement 3, while enhancing the structural stability of the escape pipe 1, the escape pipe 1 can be installed more stably on the top of the tunnel. When installing this device, the escape ladder 13 can be rolled up and laid flat on the escape door 4, so that when the escape door 4 is opened, one end of the escape ladder 13 will automatically fall to the ground. At this time, the people in the tunnel can climb to the inside of the escape pipe 1 through the escape ladder 13 to prevent being submerged by accumulated water.

[0032] An escape ladder release mechanism 7 is provided on the escape pipe 1, and the escape ladder release mechanism 7 includes a right-angle seat 701 fixedly connected to the inside of the escape pipe 1 and a limit block 706 fixedly connected to the escape door 4, a first movable plate 702 and a second movable plate 705 are slidably connected to the right-angle seat 701, and the first movable plate 702 is fixedly connected to the second movable plate 705, a spring 703 and a limit rod 704 are fixedly connected to a side of the first movable plate 702 close to the escape door 4, and the other end of the limit rod 704 is fixedly connected to the right-angle seat 701, and a limit hole adapted to the limit rod 704 is provided on the limit block 706 In the initial state, the end of the limiting rod 704 away from the first movable plate 702 is inserted into the limit of the limiting rod 704, so that the escape door 4 in the closed state can be limited, and the second movable plate 705 moves in the direction away from the escape door 4 to drive the first movable plate 702 and the limiting rod 704 to move accordingly and stretch the spring 703. When the limiting rod 704 is moved out from the inside of the limiting hole, the limit of the escape door 4 can be released, and then the escape door 4 will rotate downward under the action of its own gravity and the pressure of the escape ladder 13 to leak out the escape port, and then one end of the escape ladder 13 will automatically fall to the ground.

[0033] A top ball 712 is arranged below the second movable plate 705, and a curved surface matching the top ball 712 is arranged on the bottom surface of the second movable plate 705. The top ball 712 presses against the curved surface, and the top ball 712 moves upward to squeeze the second movable plate 705 to move away from the escape door 4. By arranging the curved surface at the bottom of the second movable plate 705, the top ball 712 can be prevented from getting stuck during the upward movement.

[0034] A plurality of water inlet grooves are provided near the bottom of the water collecting pipe 9, a circular plate 708 is fixedly connected to the inside of the water collecting pipe 9, and the circular plate 708 is located above the water inlet groove, a floating plate 709 is slidably connected to the inside of the water collecting pipe 9, and the floating plate 709 is located above the circular plate 708, a connecting rod 707 is fixedly connected to the side of the floating plate 709 away from the circular plate 708, and the end of the connecting rod 707 away from the floating plate 709 passes through the water collecting pipe 9 and the connecting pipe 14 in sequence and is fixedly connected to the top ball 712. When water accumulates seriously in the tunnel, the accumulated water will be poured into the interior of the water collecting pipe 9 through the water inlet groove.

[0035] A float 710 is installed at the bottom of the floating plate 709, and a through hole is opened inside the circular plate 708 for the float 710 and water to pass through. The accumulated water poured into the water collecting pipe 9 will drive the float 710 and the floating plate 709 to float upward, and the upward movement of the floating plate 709 can drive the connecting rod 707 and the top ball 712 to move upward. The upward movement of the top ball 712 can push the second movable plate 705 to move away from the escape door 4. The movement of the second movable plate 705 in the direction away from the escape door 4 can drive the first movable plate 702 and the limiting rod 704 to move away from the escape door 4 and stretch the spring 703. When the limiting rod 704 is moved out of the limiting hole, the limit of the escape door 4 can be released, and then the escape door 4 will rotate downward under the action of its own gravity and the pressure of the escape ladder 13 to leak out the escape port, and then one end of the escape ladder 13 will automatically fall to the ground.

[0036] A second filter screen 711 is installed inside each water inlet tank. By providing the second filter screen 711, it is possible to prevent accumulated water carrying impurities from entering the water collection pipe 9.

[0037] A baffle frame 10 is fixedly connected to the interior of the escape pipe 1. The right-angle seat 701 and the second movable plate 705 are both located inside the baffle frame 10. The baffle frame 10 can hide the right-angle seat 701 and the top ball 712 to prevent the escapees inside the escape pipe 1 from touching them.

[0038] A first avoidance groove 11 adapted to the limit rod 704 is provided inside the baffle frame 10, and a second avoidance groove 12 adapted to the limit rod 704 is provided inside the escape pipe 1. By setting the first avoidance groove 11 and the second avoidance groove 12, when the accumulated water recedes and the escape ladder 13 and the escape door 4 are controlled to be reset, it is convenient for the staff to press the limit rod 704 by hand. When the escape door 4 is rotated to the initial position, the limit rod 704 is released. Under the action of the spring 703, one end of the limit rod 704 will be inserted into the inside of the limit hole again to limit the escape door 4.

[0039] The docking mechanism 2 includes a sleeve 201, and two symmetrical retaining rings 203 are fixedly connected inside the sleeve 201. The ends of two adjacent escape pipes 1 that are close to each other are respectively pressed against the two retaining rings 203 and fixedly connected to the sleeve 201 through a second flange. By setting the sleeve 201, retaining ring 203 and second flange, stable docking between two adjacent escape pipes 1 can be achieved.

[0040] A plurality of ventilation grooves are provided on the sleeve 201, and the ventilation grooves are located between two retaining rings 203. A first filter screen 202 is installed inside each ventilation groove. The ventilation grooves and retaining rings 203 can improve the air permeability of the escape duct 1 while preventing dust and impurities from entering the interior of the escape duct 1.

[0041] A climbing mechanism 8 is provided inside the escape pipe 1, and the climbing mechanism 8 includes a first curved plate 801, a second curved plate 802 and a third curved plate 803. The first curved plate 801, the second curved plate 802 and the third curved plate 803 are all installed inside the escape pipe 1, and the first curved plate 801 is located on the back of the baffle frame 10, and the second curved plate 802 and the third curved plate 803 are respectively located on both sides of the baffle frame 10. After the escapee enters the interior of the escape pipe 1, the escapee can be distributed on both sides of the center of the escape pipe 1, with one part located on the first curved plate 801 and the other part located on the second curved plate 802 and the third curved plate 803, so that the escapee can escape more efficiently while avoiding the baffle frame 10.

[0042] A group of footrest grooves 804 are provided inside the first curved plate 801, the second curved plate 802 and the third curved plate 803. A group of flexible handles 805 are fixedly connected inside the first curved plate 801, the second curved plate 802 and the third curved plate 803, and the flexible handles 805 are staggered with the footrest grooves 804. The cooperation between the footrest grooves 804 and the flexible handles 805 can facilitate the escapees to climb and move inside the escape pipe 1.

[0043] Working principle: When the tunnel is seriously flooded, the accumulated water will flow into the water collecting pipe 9 from the water inlet trough, and the accumulated water flowing into the water collecting pipe 9 will drive the floating ball 710 and the floating plate 709 to float upward, and the floating plate 709 moves upward to drive the connecting rod 707 and the top ball 712 to move upward, and the top ball 712 moves upward to push the second movable plate 705 to move away from the escape door 4, and the second movable plate 705 moves away from the escape door 4 to drive the first movable plate 702 and the limit rod 704 to move away from the escape door 4 and stretch the spring 703. When the limiting rod 704 is moved out from the inside of the limiting hole, the limiting of the escape door 4 can be released, and then the escape door 4 will rotate downward to reveal the escape opening under the action of its own gravity and the pressure of the escape ladder 13, and then one end of the escape ladder 13 will automatically fall to the ground. Then the people in the tunnel can climb to the inside of the escape pipe 1 through the escape ladder 13 to prevent being submerged by accumulated water. Moreover, since multiple escape pipes 1 are installed end to end inside the tunnel, each escape pipe 1 can accommodate escaping people, so that people at different positions in the tunnel can achieve rapid escape.
