Description

Technical Field

[0001] This application relates to the field of train technology, and more specifically, to a water tank assembly and a track inspection vehicle. Background Technology

[0002] Track inspection vehicles are special inspection vehicles used in railway operation and maintenance. They are used for automated detection of track damage (such as rail cracks, internal defects, surface wear, etc.) and tunnel conditions, ensuring train operation safety by accurately identifying potential hazards.

[0003] The track inspection vehicle is equipped with a water tank for supplying water to the train. Currently, the track inspection vehicle only has a water inlet on one side, which limits the location where the train can be parked for water injection.

[0004] Therefore, figuring out how to inject water into the water tank from either side of the train is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a water tank assembly that allows water to be injected into the water tank from either side of the train;

[0006] Another objective of this application is to provide a track inspection vehicle having the aforementioned water tank assembly.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] The first aspect of this application provides a water tank assembly for installation on a train, comprising:

[0009] At least two water tanks;

[0010] A water tank connecting pipe is provided, through which each of the water tanks is connected, and the water tank connecting pipe is connected to the lower side of each of the water tanks;

[0011] Water injection pipes, wherein two of the water tanks are equipped with water injection pipes, and the water injection ports of the two water injection pipes are respectively arranged on both sides of the train;

[0012] A water supply pipe is connected to one of the water tanks, and a water supply switch valve is installed on the water supply pipe.

[0013] In one specific embodiment, the system further includes a water tank drain pipe connected to the water tank connecting pipe, and the water tank drain pipe is equipped with a drain switch valve.

[0016] In one specific embodiment, the water tank is provided with an inlet and an overflow port on its upper side, and a connection port on its lower side.

[0017] At least two of each of the following interfaces are provided: water inlet, overflow, and connection. The water injection pipe is connected to one of the water inlet interfaces, the water tank connection pipe is connected to one of the connection interfaces, and the overflow pipe is connected to one of the overflow interfaces. The other water inlet, overflow, and connection interfaces are sealed with screw plugs.

[0018] In one specific embodiment, the top of the water tank is provided with an air cap that communicates with the atmosphere;

[0019] And / or,

[0020] The top of the water tank is equipped with a lifting base for use with lifting equipment;

[0021] And / or,

[0023] And / or,

[0024] The side walls of the water tank are reinforced;

[0029] And / or,

[0030] The water tank is a stainless steel water tank;

[0031] And / or,

[0032] The diameter of the water injection pipe is smaller than the diameter of the water tank connecting pipe;

If one side's water injection system malfunctions, the other side can continue normal water injection operation. In cold climates, the water inlet on the sunny side should be used first to reduce the risk of pipe freezing and blockage.

[0065] This application discloses a water tank assembly that allows water to be injected into the tank from either side of the train;

[0066] This application also discloses a track inspection vehicle having the above-mentioned water tank assembly.

[0067] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0068] like Figure 1 and Figure 2 As shown in the embodiment of this application, the water tank assembly is used to be arranged on a train. The water tank assembly includes a water tank 100, a water tank connecting pipe 500, a water injection pipe 300, and a water supply pipe 700.

[0069] Traditional water tanks have two installation locations, such as roof-mounted water tanks and under-vehicle water tanks. Roof-mounted water tanks are suspended from the ceiling inside the vehicle and have a relatively small volume. Under-vehicle water tanks are suspended from the floor of the vehicle and, because they are located externally, are prone to freezing in winter.

[0070] In this embodiment, there are at least two water tanks 100. By setting multiple water tanks 100, the total water storage capacity can be increased while maintaining the small volume of each water tank 100. The small volume of the water tanks 100 makes them easy to arrange inside the train carriage 800.

[0071] Each water tank 100 is connected by a water tank connecting pipe 500, which is connected to the lower side of each water tank 100. When water is poured into one of the water tanks 100, the water settles at the bottom of that water tank 100, causing the water level to gradually rise. When the water level rises to the height of the water tank connecting pipe 500, it flows into the other water tanks 100 through the water tank connecting pipe 500, gradually filling each water tank 100.

[0072] When the water in water tank 100 is used, the water levels in all water tanks 100 drop synchronously under the action of the water tank connecting pipe 500. When the water level drops to the height of the water tank connecting pipe 500, the water level in the other water tanks 100 will stop dropping, except for the water tank 100 where water is being drained, which will continue to drop. Therefore, the water tank connecting pipe 500 should be connected to a lower position in the water tank 100, for example, when the water tank connecting pipe 500 is connected to the bottom of the water tank 100, all the water in the water tanks 100 can be drained.

[0073] Two water tanks 100 are equipped with water injection pipes 300, and the water inlets of the two water injection pipes 300 are respectively arranged on both sides of the train. Specifically, the two water inlets can be arranged on both sides under the train, so that water can be injected into the water tanks 100 from either side under the train through the water injection pipes 300.

[0074] The water supply pipe 700 is connected to one of the water tanks 100, and a water supply switch valve 701 is installed on the water supply pipe 700. It should be noted that only one water tank 100 needs to be installed with the water supply pipe 700, but it can also be installed in other water tanks 100. In this embodiment, the number of water supply pipes 700 is not limited.

[0075] The water tank assembly disclosed in this application includes at least two water tanks 100. Using multiple water tanks 100, while maintaining the same water storage capacity, reduces the volume of a single water tank 100, making it easier to arrange the water tanks 100 inside the train carriage 800 and preventing icing problems in winter caused by placing the water tanks 100 outside the train. The water tanks 100 are connected by water tank connecting pipes 500, creating a communicating vessel state. When any one water tank 100 is filled, water can be injected into all water tanks 100 through the water tank connecting pipes 500. One water tank 100 can be connected to a water supply pipe 700 to supply water to the train carriage 800. Water injection pipes 300 are respectively installed on two of the water tanks 100, with the water inlets of the two water injection pipes 300 arranged on opposite sides of the train. This arrangement can adapt to different platform layouts, eliminating the need to adjust the train's orientation when stopping, allowing for water injection regardless of whether the train stops at a left- or right-facing platform. Furthermore, it can shorten station dwell time. Since water inlets are installed on both sides of the train, simultaneous water injection from both sides is allowed, increasing the maximum flow rate by 40-60%. If the water injection equipment on one side malfunctions, the equipment on the other side can continue normal operation. In cold climates, the water inlet on the sunny side can be used first to reduce the risk of pipe freezing.

[0076] When the train is not in use for a long time, in summer when the ambient temperature is above 0℃, there is no risk of the water in the water tank 100 and the pipes freezing; in winter when the ambient temperature is below 0℃, the water in the water tank 100 and the pipes is at risk of freezing, and once it freezes, there will be problems with the water tank 100 and the pipes being damaged.

[0077] Based on this, the water tank assembly disclosed in this embodiment may further include a water tank drain pipe 600 connected to the water tank connecting pipe 500, and a drain valve 601 is provided on the water tank drain pipe 600. When there is a need to empty the water tank, the drain valve 601 can be opened, allowing the water in the water tank 100 and the water in the water tank connecting pipe 500 to be discharged through the water tank drain pipe 600 under the action of gravity, preventing the water tank 100 and the water tank connecting pipe 500 from freezing in winter due to prolonged disuse. Other pipelines can also allow water in the pipeline to flow out under the action of gravity by opening the corresponding valve body.

[0078] The water tank drain pipe 600 can be connected to the lowest point of the water tank connecting pipe 500 to prevent water in the water tank connecting pipe 500 from not being completely drained. Specifically, the shape of the water tank connecting pipe 500 can be designed so that it has a lowest point, and gradually rises from this lowest point to both ends until it connects with the water tank 100, so that the water level is highest at the end of the water tank connecting pipe 500, and the height gradually decreases from the end of the water tank connecting pipe 500 to the lowest point. Connecting the water tank drain pipe 600 to the lowest point of the water tank connecting pipe 500 allows the water in the water tank connecting pipe 500 to be completely drained.

[0079] When filling water tank 100, there is a possibility of overfilling. That is, when water tank 100 is full, the water filling device cannot be shut off in time, causing excessive pressure inside water tank 100. This affects the service life of water tank 100 and may lead to leaks at the joints. Of course, when water tank 100 is full, water may also overflow through other joints, causing the overflowing water to flow along the outer wall of water tank 100 and contaminate train carriage 800.

[0080] Therefore, in this embodiment, an overflow pipe 400 is connected to the upper side of the water tank 100, and the outlet end of the overflow pipe 400 extends to the outside of the train. When the water tank 100 is filled with water, when the water level rises to the installation height of the overflow pipe 400, the water can be discharged to the outside of the train through the overflow pipe 400, thereby preventing the water pressure from rising due to the water tank 100 being full, and thus avoiding the problem of reduced water tank life due to increased water pressure. Since the water overflows to the outside of the train through the overflow pipe 400, it will not directly overflow from other interfaces and contaminate the train carriage 800.

[0081] All pipes connected to the water tank 100 are connected through interfaces on the water tank 100. These interfaces are typically welded to the locations on the water tank 100 where pipes need to be connected; they are usually threaded to facilitate connection with fittings on the pipes. If a problem occurs with the interface, the water tank 100 will leak at that point, and the interface is difficult to repair.

[0082] Based on this, such as Figures 3-6 As shown in a specific embodiment of this application, the upper side of the water tank 100 is provided with a water inlet 115 and an overflow 114, and the lower side of the water tank 100 is provided with a connecting interface 112. It should be noted that the water inlet 115, the overflow 114, and the connecting interface 112 can all be welded to the water tank 100, and holes need to be opened at the positions of the water tank 100 corresponding to the above interfaces so that each interface is in a connected state with the water tank 100.

[0083] At least two of each of the following water inlet ports 115, overflow ports 114, and connecting ports 112 are provided: a water inlet pipe 300 connects to one of the water inlet ports 115, a water tank connecting pipe 500 connects to one of the connecting ports 112, and an overflow pipe 400 connects to one of the overflow ports 114. The other water inlet ports 115, overflow ports 114, and connecting ports 112 are spare ports. When not in use, they can be sealed with plugs. The spare ports are identical to the actual ports. If the threads of the actual port are damaged, the spare port can be used directly, reducing maintenance workload and increasing the service life of the water tank 100.

[0084] It should be noted that the actual interface and the spare interface can be used alternately to increase the service life of the water inlet interface 115, the overflow interface 114 and the connection interface 112.

[0085] In addition, one of the water tanks 100 is also equipped with two water supply interfaces 113, and the water supply pipe 700 is connected to one of the water supply interfaces 113. The other water supply interface 113 is a spare interface, which can be sealed with a screw plug when not in use. The spare interface is the same as the actual interface. When the thread of the actual interface is damaged, the spare water supply interface 113 can be used directly, reducing maintenance workload and increasing the service life of the water tank 100.

[0086] In one specific embodiment of this application, an air cap 106 communicating with the atmosphere is provided on the top of the water tank 100. The air cap 106 maintains atmospheric pressure balance inside and outside the water tank 100, allowing water to flow in and out without siphoning. Since the air cap 106 is open to the atmosphere, to prevent substances in the environment from entering the water tank 100 through the air cap 106 and causing water pollution, an air filter can also be installed inside the air cap 106 in this embodiment. This filter filters the air entering the water tank 100 during drainage, preventing impurities from entering the water tank 100 and contaminating the water quality. The air filter is replaceable and can be replaced according to usage time and filtration conditions to maintain filtration effectiveness.

[0087] To facilitate the installation of the water tank 100, in this embodiment, a lifting base 101 for use with lifting equipment is provided on the top of the water tank 100. Multiple lifting bases 101 can be provided, evenly distributed around the center of gravity of the water tank 100 on the top of the water tank 100. This allows the water tank 100 to be lifted in a usable position after the lifting equipment connects to each lifting base 101, preventing the water tank 100 from rotating around its center of gravity during lifting. In this embodiment, the lifting bases 101 are arranged on the top of the water tank 100 and around its center of gravity. Therefore, when lowering the water tank 100 after it has been lifted into place, the water tank 100 does not need to be flipped and can be placed directly on the floor of the carriage.

[0088] The outer wall of the water tank 100 is also equipped with a detachable handrail 104. Specifically, the water tank 100 can be a cubic structure. Except for the top and bottom, one of its facades needs to be flush with the side wall of the train carriage 800 to improve installation stability. The other three facades can all be equipped with detachable handrails 104, or some facades can be selected for installation. During the hoisting of the water tank 100, the operator can hold the detachable handrail 104 to help control the position of the water tank 100 and prevent the water tank 100 from swaying and shaking during hoisting, thus avoiding collisions and damage to surrounding objects.

[0089] The detachable handrail 104 has mounting plates at both ends, and the water tank 100 has mounting seats at corresponding positions. The mounting plates at both ends of the detachable handrail 104 can be detachably fixed to the mounting seats by fasteners. After the water tank 100 is installed, the detachable handrail 104 can be removed, or it can remain in place. Those skilled in the art can choose according to their needs.

[0090] To improve the strength of the water tank 100, in this embodiment, the side wall of the water tank 100 is provided with reinforcing ribs 102. The number of reinforcing ribs 102 can be selected according to requirements. The reinforcing ribs 102 can be set on the inner wall or the outer wall of the water tank 100, as long as the compressive and impact resistance of the water tank 100 can be guaranteed. This embodiment does not limit the specific location and number of the water tank 100.

[0091] In one specific embodiment of this application, a partition 103 is provided inside the water tank 100, which divides the water tank 100 into multiple water chambers. The partition 103 serves as an internal support component of the water tank 100, enhancing its overall rigidity and resisting deformation caused by hydrostatic pressure, which is particularly crucial for large water tanks 100. The partition 103 has permeable holes 1031, which maintain communication between the water chambers on both sides of the partition 103, preventing differences in water level between the two chambers.

[0092] Even though the water tank 100 is located inside the train, there is still a risk of freezing when the train is in use during winter. Therefore, in this embodiment, an electric heating rod 111 is installed on the side of the water tank 100. The electric heating rod 111 extends into the water tank 100 to heat the water inside, reducing the risk of freezing in winter.

[0093] The water tank 100 can be a stainless steel water tank. Specifically, two water tanks 100 can be provided, and the two water tanks 100 are the same size. For example, the volume of each water tank 100 can be 1510mm × 1000mm × 600mm, and both can be made of stainless steel. They are arranged on both sides of the train car 800 inside the train to balance the center of gravity of the train. It should be noted that the water tank 100 can also adopt other sizes, and the volume of the water tank 100 can be designed according to the actual application scenario.

[0094] When water is injected from one side, the water in the water tank 100 that needs to be injected flows quickly into the other water tank 100. In this embodiment, the diameter of the water injection pipe 300 is smaller than the diameter of the water tank connecting pipe 500. For example, the water injection pipe 300 can be selected with a diameter of 28 mm, while the water tank connecting pipe 500 can be selected with a diameter of 42 mm. Of course, the overflow pipe 400 can also be selected with the same diameter as the water injection pipe 300. Since the diameter of the water tank connecting pipe 500 is larger than the diameter of the water injection pipe 300, when water is injected from one side, the water in the water injection tank can quickly reach the other water tank 100 through the larger diameter water tank connecting pipe 500, enhancing the synchronization of the water levels in the two water tanks 100.

[0095] To further prevent the water tank 100 and water pipes from freezing and cracking, in this embodiment, the water tank 100, water tank connecting pipe 500, water injection pipe 300 and water supply pipe 700 are all wrapped with insulation cotton and / or heat tracing tape. By wrapping with insulation cotton and / or heat tracing tape, the risk of pipe bursting caused by water pressure fluctuations in winter can be reduced, and the stability of the system can be enhanced.

[0096] There is a risk of shaking during train operation. After a long period of use, the various interfaces and pipe connections of the water tank 100 may become loose. Therefore, when the train shakes, water may spill out of the water tank 100 at the interfaces and pipe connections, causing water to accumulate inside the train car 800. This water accumulation can damage the train floor structure.

[0097] Based on this, the water tank assembly disclosed in this embodiment may further include a drain tray 200, on which each water tank 100 is disposed. Only one drain tray 200 may be provided, and all water tanks 100 may be disposed within the same drain tray 200. Alternatively, a separate drain tray 200 may be provided for each water tank 100, meaning each water tank 100 is placed within an independent drain tray 200.

[0098] The drainage tray 200 is used to collect water overflowing from the interface of the water tank 100, preventing water accumulation and damage to the train floor. A tray drain pipe is connected to the bottom of the drainage tray 200, with its outlet extending to the outside of the train. The tray drain pipe can drain the accumulated water collected by the drainage tray 200.

[0099] Since the drain pipe can quickly drain the water collected by the drain tray 200, the drain tray 200 does not need to be designed to be very deep. It should be noted that if the drain tray 200 is designed to have a large volume and can hold more water, then the drain pipe may not be necessary, and the operator can simply drain the water from the drain tray 200 periodically.

[0100] Although a connection interface 112 is provided on the lower side of the water tank 100, the water in the water tank 100 can be drained through the water tank connection pipe 500 and the water tank drain pipe 600 connected to the connection interface 112. However, it is still impossible to drain all the water in the water tank 100. Over time, a lot of dirt will accumulate at the bottom of the water tank 100 and cannot be drained, which will inevitably affect the water quality in the water tank 100.

[0101] Therefore, in this embodiment, a cleaning drain port 107 is provided at the bottom of the water tank 100. The number of cleaning drain ports 107 is not limited to one; multiple cleaning drain ports 107 can be set at different positions at the bottom as needed to improve the drainage effect. After the cleaning drain port 107 is opened, the water in the water tank 100 can be completely drained, and the water in the water tank 100 can be drained clean.

[0102] When the water tank 100 needs cleaning, water can be injected into the water tank 100 through the water injection pipe 300 while the cleaning drain port 107 is opened. The water injected into the water tank 100 through the water injection pipe 300 falls to the bottom from a high point in the water tank 100, impacting the dirt at the bottom to form sewage, which is then discharged through the cleaning drain port 107. This can prevent sewage from accumulating in the water tank 100 after prolonged use.

[0103] To further achieve the purpose of cleaning the water tank 100, in this embodiment, at least one side of the water tank 100 is provided with a cleaning port 109 for hand insertion. The cleaning port 109 allows hand insertion, and cleaning tools can also be inserted into the water tank 100 to clean stains accumulated after prolonged use. Water injected into the water tank 100 via the water inlet pipe 300 can easily scrape off the stains inside the water tank 100, dissolving them in the water to form wastewater, which is ultimately discharged through the cleaning drain port 107.

[0104] In one specific embodiment of this application, a level gauge 105 and / or an observation window are provided on the side of the water tank 100. The level gauge 105 can be a mechanical level gauge or an electronic level gauge. This embodiment does not limit the specific type of the level gauge 105, as long as it can detect the water level in the water tank 100. An observation window can also be provided on the side of the water tank 100, through which the water level in the water tank 100 can be easily observed.

[0105] This application also discloses a track inspection vehicle, which includes a train car 800 and a water tank assembly. The water tank assembly is the same as disclosed in the above embodiment, consisting of two water tanks 100 arranged inside the train car 800 on either side to balance the train's center of gravity. A base 108 is typically provided at the bottom of each water tank 100, supporting the tank on the car floor. The base 108 raises the height of the water tank 100's base plate, facilitating drainage from the drain outlet 107.

[0106] The track inspection vehicle disclosed in this application has the above-mentioned water tank assembly, and therefore possesses all the technical effects of the above-mentioned water tank assembly, which will not be repeated here.

[0107] Because the train will shake during operation, the water in the water tank 100 will flow and impact the inner wall of the tank. As the water fluctuates due to the train's shaking, the center of gravity of the water tank 100 will continuously change, and the water tank 100 may even shake inside the carriage. If the shaking is too great, there is even a risk of it overturning.

[0108] To prevent the water tank 100 from tipping over during train operation, in this embodiment, a fixing plate 110 is provided on the outer side of the water tank 100, and the fixing plate 110 is fixed to the inner wall of the train car 800 by fasteners. In this embodiment, the fixing plate 110 can fix the vertical surface of the water tank 100 to the inner wall of the train car 800. During train operation, when the water in the water tank 100 fluctuates, it will cause the center of gravity of the water tank 100 to change. However, because the side of the water tank 100 is fixed to the inner wall of the train car 800, the stability of the water tank 100 is improved, and the tipping over of the water tank 100 during train operation is avoided.

[0109] The water tank connecting pipe 500, water injection pipe 300 and water supply pipe 700 may have horizontal sections depending on the space layout requirements. A horizontal section means that the section of pipe is in a horizontal state. Therefore, there is a possibility of water accumulation in the horizontal section, which prevents the water from being effectively drained and leads to the risk of freezing in winter.

[0110] To ensure complete drainage of the water pipes, in this embodiment, adjusting devices are installed on the horizontal sections of the water tank connecting pipe 500, the water injection pipe 300, and the water supply pipe 700. These adjusting devices are used to tilt the horizontal sections of the water tank connecting pipe 500, the water injection pipe 300, and the water supply pipe 700 downwards along the water flow direction. The downward tilt angle can be 10°, but it can also be adjusted to other angles, as long as it tilts downwards along the water flow direction. Adjusting the horizontal sections of the pipes to tilt downwards along the water flow direction allows them to drain under gravity, reducing the risk of water accumulation.

[0111] The horizontal sections of the water tank connecting pipe 500, water injection pipe 300, and water supply pipe 700 can be fixed on the adjusting device. The adjusting device can be set at the corresponding position in the train car 800. The height of the adjusting device can be adjusted, for example, by adjusting the adjusting screw, thereby changing the inclination angle of the horizontal sections of the water tank connecting pipe 500, water injection pipe 300, and water supply pipe 700 to facilitate water discharge.
