Description

Technical Field

[0001] This invention belongs to the technical field of railway passenger station platform equipment, specifically relating to a water supply device and method for high-volume passenger cars suitable for the space under narrow platforms. Background Technology

[0002] Modern high-speed rail hub stations often employ cantilevered platform designs to achieve a more three-dimensional and aesthetically pleasing space. However, this design results in minimal vertical clearance for water supply equipment beneath the platform, typically less than 400mm. Simultaneously, the high-flow-rate water supply from high-speed trains places stringent requirements on the diameter (DN200) of the station's main water supply network.

[0003] Traditional water supply equipment is bulky and cannot be installed in this confined space. Existing flattened water supply devices mainly rely on a single medium-diameter flexible hose coiled inside a hose reel. A single hose cannot directly meet the flow requirements of a DN200 main pipe. Furthermore, the DN200 main pipe itself is too thick and rigid to be directly connected to the flattened hose reel and moved along the multi-jointed arm. Therefore, there is an urgent need for a new type of water supply device that can both accept the flow of a DN200 main pipe and meet the requirements of extreme flattening and highly flexible addressing. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a water supply device and method for high-volume passenger vehicles suitable for the space under narrow platforms, which solves the contradiction between high-volume main pipe access and the narrow space under the platform, while ensuring easy operation and flexible addressing.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A water supply device for high-volume passenger vehicles suitable for use in confined spaces under narrow platforms, characterized in that:

[0007] It includes a concealed mounting module, which is fixedly installed on the bottom surface of the platform cantilever structure; the concealed mounting module is equipped with a flat constant force hose module and a horizontal sliding guide rail;

[0008] The horizontal sliding guide rail is arranged parallel to the length direction of the rail; the fixed end of the multi-joint water delivery arm is slidably connected to the horizontal sliding guide rail;

[0009] The station's water supply network interface is connected to a fixed distribution manifold device; the fixed distribution manifold device is located below the platform cantilever structure; the outlet of the fixed distribution manifold device is connected to a water supply hose bundle; the water supply hose bundle includes multiple flexible branch hoses connected in parallel along the horizontal direction.

[0010] The water supply hose bundle is horizontally coiled inside the flattened constant force hose reel module;

[0011] The other end of the water supply hose bundle passes through the flattened constant force hose module; the exposed section of the water supply hose bundle is connected in parallel with the multi-joint water delivery arm; at the water supply end of the water supply hose bundle, multiple flexible branch hoses are connected to the manifold; the water pipe at the outlet end of the manifold is injected into the vehicle's water inlet through the water supply connector.

[0012] Furthermore, the multi-jointed water delivery arm includes arm segment A and arm segment B connected by a hinge shaft.

[0013] Furthermore, the hinge axes of the multi-jointed water delivery arm are all perpendicular to the horizontal plane.

[0014] Furthermore, the joint hinge of the multi-joint water supply arm is provided with multiple parallel hose guide wheel bundles. Each flexible branch hose in the water supply hose bundle is attached to and passes around a corresponding hose guide wheel. The water supply hose bundle is arranged in a flat manner when passing around the hose guide wheel bundle.

[0015] Furthermore, the flattened constant force tube winding module includes a flattened outer shell, within which a servo motor and a tension sensor are installed.

[0016] Furthermore, it also includes an intelligent temperature control and antifreeze system, including a PTC self-regulating heating cable, an aerogel composite insulation layer, a temperature sensor array, and an intelligent controller; the aerogel composite insulation layer wraps the distribution manifold device, the water supply hose bundle, and the water collector.

[0017] A water supply method for high-volume passenger vehicles suitable for use in confined spaces under narrow platforms, specifically:

[0018] After the vehicle stops, the operator pulls the water inlet connector; the tension sensor monitors the tension change when the water inlet connector is pulled out in real time. When the tension sensor detects that the water inlet connector is pulled outward, the servo motor rotates forward to release the horizontally coiled water inlet hose bundle.

[0019] The water inlet connector drives the multi-joint water delivery arm to move horizontally along the horizontal sliding guide rail; at the same time, arm section A and arm section B unfold in the horizontal plane.

[0020] When the water source switch is turned on, the water flows from the station's water supply network interface into the fixed distribution manifold device; the fixed distribution manifold device distributes the large flow of water from the water supply network into multiple parallel branch water flows, and each branch water flow enters the flexible branch hose of the water supply hose bundle.

[0021] At the water inlet end of the water inlet hose bundle, the manifold recombines the flow rates of multiple flexible branch hoses into a large flow rate; the water pipe at the outlet end of the manifold is injected into the vehicle's water inlet through the water inlet connector.

[0022] After the operation is completed, the servo motor automatically reverses to wind the water supply hose bundle back at a constant speed and maintains the set constant tension.

[0023] Furthermore, the intelligent controller collects ambient and pipe wall temperatures in real time through a temperature sensor array. When the ambient temperature is greater than or equal to 3°C, the PTC self-regulating heating cable is in a dormant state. When the ambient temperature is lower than 3°C but higher than -10°C, the intelligent controller controls the pipe wall temperature of each branch hose to be maintained at 5°C through the PTC self-regulating heating cable. When the ambient temperature is lower than -10°C, the intelligent controller controls the pipe wall temperature to be maintained above 10°C through the PTC self-regulating heating cable.

[0024] The beneficial effects of this invention are:

[0025] 1) This invention adopts a high-flow-rate branch parallel water supply system, which distributes the high flow rate of the DN200 main pipe to multiple thinner branch hoses, so that the total flow rate is close to the DN200 standard, while maintaining the flat structure of the whole machine (especially the hose reel module and the robotic arm), thus solving the contradiction between high flow rate and small space.

[0026] 2) This invention uses a sliding guide rail in conjunction with a multi-joint arm, which can cope with the positional error when the vehicle is parked and cover the different water inlet positions of different vehicles;

[0027] 3) In this invention, multiple parallel branch hose bundles pass through in a flat bundle shape at the joint hinge and are individually guided by multiple parallel hose guide wheel bundles, which significantly reduces bending stiffness and pulling resistance.

[0028] 4) The dynamic impedance system composed of the servo motor and tension sensor of this invention reduces the difficulty of operation for workers;

[0029] 5) This invention adopts an intelligent temperature control and antifreeze system, which ensures the equipment's all-weather operation capability in frigid climates and improves the equipment's applicability. Attached Figure Description

Detailed Implementation

[0035] The present invention will now be described in detail with reference to specific embodiments.

[0036] This invention provides a water supply device and method for high-volume passenger trains in a confined space under a platform that meets the requirements for DN200 main pipe access. It solves the contradiction between high-volume main pipe access and the confined space under the platform, while ensuring easy operation and flexible addressing.

[0037] like Figure 1 , 2 As shown, the water supply device for high-volume passenger vehicles applicable to the space under narrow platforms of the present invention includes a hidden mounting module 2, which is fixedly installed on the bottom surface of the cantilever structure 1 of the platform; a flattened constant force hose module 5 and a horizontal sliding guide rail 3 are installed on the hidden mounting module 2.

[0038] The horizontal sliding guide rail 3 is set parallel to the length direction of the rail 7; the fixed end of the multi-joint water delivery arm 4 is slidably connected to the horizontal sliding guide rail 3, and the water delivery arm 4 moves horizontally along the horizontal sliding guide rail 3.

[0039] The multi-joint water supply arm 4 includes arm segments A4a and B4b connected by hinge shafts 41. The hinge shafts 41 of the multi-joint water supply arm 4 are all perpendicular to the horizontal plane, so that each arm segment can only rotate in the horizontal plane. The whole device is hidden in the clearance below the platform cantilever structure 1 and does not protrude from the edge of the platform.

[0040] like Figure 3 , 4As shown, to guide the water supply hose bundle 6 smoothly through the joints of the multi-joint water delivery arm 4, multiple parallel hose guide wheel bundles 11 are provided at the joint hinges of the multi-joint water delivery arm 4. These hose guide wheel bundles 11 are specialized structures adapted to the flat hose bundle arrangement. Specifically, they include a vertically positioned central main shaft. The upper and lower ends of this central main shaft are fixed to the hinge shafts 41 of arm segments A4a and B4b of the multi-joint water delivery arm 4 via mounting brackets. On the central main shaft, multiple layers of independent single-groove guide wheels are coaxially mounted vertically. Adjacent layers of single-groove guide wheels are separated by isolation gaskets, allowing each layer of single-groove guide wheels to rotate independently around the central main shaft via internal bearings. Each flexible branch hose in the water supply hose bundle 6 is embedded and fits around a corresponding single-groove guide wheel, and the water supply hose bundle 6 is arranged in a flattened manner when passing around the hose guide wheel bundles 11. Single-groove guide wheel 11a (with oblique cross-section, I-shaped cross-section, groove facing outward); isolation gasket 11b (placed between adjacent 11a); central main shaft 11c is a longitudinal through-piece; mounting brackets 4a / 4b (fixed end of hinge shaft) for arm segment A and arm segment B. Water supply hose bundle 6 (4 circular cross-sections on the right, nested in the groove). During rotation, multiple branch hoses are forced to be arranged in parallel and flat into a bundle, each fitting against the corresponding independent guide wheel, significantly reducing the mechanical resistance during multi-joint arm rotation, mutual interference between pipelines, and pipe wall wear.

[0041] The station water supply network interface 12 is connected to the fixed distribution manifold device 13; the fixed distribution manifold device 13 is located below the platform cantilever structure 1; the outlet of the fixed distribution manifold device 13 is connected to the water supply hose bundle 6; the water supply hose bundle 6 includes multiple flexible branch hoses connected in parallel along the horizontal direction; the fixed distribution manifold device 13 distributes the large flow of water from the DN200 water supply network into multiple parallel branch flows.

[0042] The water supply hose bundle 6 is horizontally coiled inside the flattened constant force hose reel module 5. Due to the small diameter and high flexibility of each branch hose, the hose bundle 6 is coiled in parallel flat within the hose reel module, which greatly compresses the vertical thickness of the equipment, allowing it to be perfectly hidden in the narrow clearance space under the platform cantilever structure 1.

[0043] The other end of the water supply hose bundle 6 passes through the flattened constant force hose module 5; the exposed section of the water supply hose bundle 6 is connected in parallel with the multi-joint water delivery arm 4; at the water supply end of the water supply hose bundle 6, multiple flexible branch hoses are connected to the manifold 14; the manifold 14 is used to re-combine the flow of multiple flexible branch hoses into a large flow of water; the water pipe at the outlet end of the manifold 14 is injected into the vehicle water inlet 9 through the water supply connector 8.

[0044] The flattened constant force hose reel module 5 includes a flattened housing 51, inside which are a servo motor 52, a tension sensor 53, and a central reel for winding the water supply hose bundle 6. The servo motor 52 is fixedly mounted on the inner wall of the flattened housing 51. The output shaft of the servo motor 52 is connected to the rotating main shaft of the central reel via a transmission mechanism (such as a reduction gear set or chain drive) to drive the central reel to rotate forward to release or reverse to rewind the water supply hose bundle 6.

[0045] Tension sensor 53 is located at the outlet of the flat housing 51. The base of tension sensor 53 is fixedly connected to the flat housing 51, and its sensing end is connected to a set of floating guide rollers. The water supply hose bundle 6 is led out from the central reel, passes between the floating guide rollers, and extends to the outside of the housing. When the operator pulls the water supply connector 8 from the outside, the water supply hose bundle 6 tightens and generates radial pressure on the floating guide rollers. This pressure change is directly transmitted to the sensing end of tension sensor 53, thereby achieving real-time and accurate monitoring of the pulling tension.

[0046] For frigid regions in the north, such as Fengtai Station, the system also includes an intelligent temperature control and antifreeze system, comprising a PTC self-regulating heating cable, an aerogel composite insulation layer, a temperature sensor array, and an intelligent controller. The aerogel composite insulation layer wraps around the distribution manifold device 13, the water supply hose bundle 6, and the water collector 14, ensuring antifreeze performance while maintaining the extremely flat structural features of the entire system. The heat tracing and insulation structure is designed to be an integrated wrapping of the parallel water supply hose bundle 6, the fixed distribution manifold device 13, and the water collector 14.

[0047] This invention also provides a method for water supply to high-volume passenger vehicles suitable for use in confined spaces under narrow platforms, specifically:

[0048] After vehicle 10 stops, the operator pulls the water inlet connector 8; the tension sensor 53 monitors the tension change when the water inlet connector 8 is pulled out in real time. When the tension sensor 53 detects that the water inlet connector 8 is pulled outward, the servo motor 52 rotates forward and releases the horizontally coiled water inlet hose bundle 6.

[0049] The water inlet connector 8 drives the multi-joint water delivery arm 4 to move horizontally along the horizontal sliding guide rail 3; at the same time, arm segments A4a and B4b unfold in the horizontal plane.

[0050] When the water source switch is turned on, the water flows from the station water supply network interface 12 into the fixed distribution manifold device 13; the fixed distribution manifold device 13 distributes the large flow of water from the water supply network into multiple parallel branch water flows, and each branch water flow enters the flexible branch hose of the water supply hose bundle 6 respectively.

[0051] At the water inlet end of the water inlet hose bundle 6, the water collector 14 re-combines the flow of multiple flexible branch hoses into a large flow of water; the water pipe at the outlet end of the water collector 14 is injected into the vehicle's water inlet 9 through the water inlet connector 8.

[0052] After the operation is completed, the servo motor 52 automatically reverses to wind the water supply hose bundle 6 back at a constant speed and maintains the set constant tension.

[0053] The intelligent controller collects ambient and pipe wall temperatures in real time through a temperature sensor array. When the ambient temperature is greater than or equal to 3℃, the PTC self-regulating heating cable is in a dormant state. When the ambient temperature is lower than 3℃ but higher than -10℃, the intelligent controller controls the pipe wall temperature of each branch hose to be maintained at 5℃ through the PTC self-regulating heating cable. When the ambient temperature is lower than -10℃, the intelligent controller controls the pipe wall temperature to be maintained above 10℃ through the PTC self-regulating heating cable.
