Description

Technical Field

[0001] This utility model relates to the field of road drainage technology, and in particular to a road drainage device for airport access roads. Background Technology

[0002] An airport is a site for aircraft to take off and land, and the access roads to the airport are an indispensable part of airport construction.

[0003] In the patent application "A Highway Road Surface Drainage Device" with application number "202122068561.3", this solution involves rotating a handwheel, which in turn drives a worm gear, which in turn drives a worm wheel, which in turn drives a rotating shaft. The rotating shaft then drives a winding wheel to unwind the water hose. The top cover is opened via a handle, allowing one end of the water hose to connect to the water pump outlet. An extension pipe is pulled downwards from the bottom of the suction pipe, inserting its bottom end into the accumulated water. This allows the water pump to extract water from the road surface through the suction pipe and the extension pipe. However, this solution has some shortcomings:

[0004] As the reel drives the hose to rotate, the end of the hose furthest from the pump pipe also rotates. This means that each time the hose is unwound and rewound, the end furthest from the pump pipe must be connected to or disconnected from the pump outlet to ensure stable hose rotation. However, this requires repeated installation and disassembly each time the hose is used, which is cumbersome. Furthermore, frequent installation and disassembly can reduce the sealing of the connection, leading to leaks. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] With reference to Figures 1-3 The airport approach highway pavement drainage device comprises a bottom plate 1, a plurality of universal wheels are installed at the lower end of the bottom plate 1, and a push rod 20 is fixedly connected to the upper end of the bottom plate 1 close to the collecting box 14.

[0025] The water suction head 8, the water suction pump 10 and the winding mechanism are further included. The winding mechanism comprises a box body 2, a winding roller 5 and a water hose 7. The box body 2 is fixedly connected to the upper end of the bottom plate 1. Two vertical plates 3 are fixedly connected to the top of the box body 2. A rotating shaft 4 is rotatably connected to the side wall of the two vertical plates 3. The winding roller 5 is fixedly connected to the side wall of the rotating shaft 4. Two limiting rings 6 are fixedly connected to the side wall of the winding roller 5. The water hose 7 is wound around the side wall between the two limiting rings 6 of the winding roller 5. One end of the water hose 7 penetrates through the top of the box body 2 and is in communication with the inner wall of the water suction head 8. The water suction head 8 is fixedly connected to the lower end of the filter screen 9. The filter screen 9 can filter the impurities in the water on the airport approach highway pavement, so that the water suction pump 10 is not harmed.

[0026] The water suction pump 10 is installed at the bottom of the box body 2. The rotating joint 12 is fixedly connected to the side wall of one of the vertical plates 3 through a support. The input end of the water suction pump 10 is fixedly connected to one side of the rotating joint 12 through the water suction pipe 13. The groove 11 is formed in the end of the rotating shaft 4 close to the rotating joint 12. The end of the rotating shaft 4 close to the rotating joint 12 is fixedly connected to the side of the rotating joint 12 away from the water suction pipe 13. The end of the water hose 7 away from the water suction head 8 is in communication with the inner wall of the groove 11.

[0027] It needs to be explained that the rotary joint 12 is a 360-degree rotating closed rotary connector for conveying medium, which is the prior art, that is, during the rotation of the rotating shaft 4, the winding roller 5 and the water hose 7, the position of the water suction pipe 13 remains unchanged, thereby realizing the constant mounting and connection of the water suction pipe 13 and one end of the water hose 7. When winding and unwinding the water hose 7, the water suction pipe 13 and one end of the water hose 7 do not need to be disassembled, avoiding the need to assemble and disassemble them every time in the prior art, which is very cumbersome. At the same time, frequent assembly and disassembly can easily reduce the sealing between the two, thereby causing water leakage.

[0028] The side wall of the water hose 7 close to the rotary joint 12 is fixedly connected with the side wall of one of the limiting rings 6, so that during the rotation of the winding roller 5, the part of the water hose 7 connected with the groove 11 can be stably rotated.

[0029] The winding mechanism further comprises a hand wheel 16, one end of the rotating shaft 4 away from the rotary joint 12 penetrates through the side wall of the box body 2 and is fixedly connected with the hand wheel 16, the side wall of the hand wheel 16 is threadedly connected with a bolt 18, and the side wall of the box body 2 close to the hand wheel 16 is provided with a plurality of threaded grooves 17, and the bolt 18 is threadedly connected with one of the threaded grooves 17.

[0030] Further, the rotation position of the hand wheel 16 can be fixed through the cooperation of the bolt 18 and the threaded groove 17, thereby fixing the rotation position of the winding roller 5, so that the position of the water hose 7 after winding or unwinding remains stable.

[0031] The bottom plate 1 is fixedly connected with a collecting box 14 at the upper end, the water outlet pipe 15 is fixedly connected with the outlet of the water pump 10, the outlet of the water outlet pipe 15 is arranged opposite to the collecting box 14, the bottom of the collecting box 14 is fixedly connected with a drain pipe 19, and the drain pipe 19 is provided with a valve.

[0032] In the utility model, when it is necessary to drain the airport approach highway pavement, the staff pushes the push rod 20 at this time, so that the bottom plate 1 moves under the action of the plurality of universal wheels, and the bottom plate 1 moves to the place where the airport approach highway pavement needs to be drained.

[0033] Then the staff rotates the bolt 18, so that the bolt 18 is separated from the threaded groove 17, then the hand wheel 16 is rotated clockwise, and the rotating shaft 4 drives the winding roller 5 to rotate clockwise to unwind the water hose 7. At this time, the staff can pull out the water hose 7 from the box body 2, so that the water suction head 8 can be opposite to the place where the airport approach highway pavement needs to be drained, then the bolt 18 is threadedly connected with the corresponding threaded groove 17 again, and the rotation position of the winding roller 5 is fixed, so that the position of the water hose 7 after unwinding remains stable.

[0034] Subsequently, the water pump 10 is started, and then the accumulated water on the airport approach road surface is sucked into the water pump 10 through the water suction head 8, the water hose 7, the groove 11, the rotary joint 12 and the water suction pipe 13, and then the accumulated water is stored in the collecting box 14 through the water outlet pipe 15, so as to complete the drainage of the accumulated water on the airport approach road surface.

[0035] After the accumulated water is cleaned, the staff member rotates the bolt 18 and separates it from the threaded groove 17 again, and then rotates the hand wheel 16 counterclockwise, so that the rotating shaft 4 drives the winding roller 5 to rotate counterclockwise, the water hose 7 is wound, the water hose 7 is prevented from being too long to affect the movement of the device, and then the bolt 18 is rotated again, so that the bolt 18 is threadedly connected with the corresponding threaded groove 17 again.

[0036] During the unwinding and winding of the water hose 7, under the action of the rotary joint 12, the rotating shaft 4, the winding roller 5 and the water hose 7 rotate, and the position of the water suction pipe 13 remains unchanged, so that the water suction pipe 13 and one end of the water hose 7 are always connected, the water suction pipe 13 and one end of the water hose 7 do not need to be disassembled during the winding and unwinding of the water hose 7, the existing technology needs to be assembled and disassembled every time, the operation is very complicated, and frequent assembly and disassembly can easily reduce the sealing between the two, thereby causing the phenomenon of water leakage.

[0037] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
