Description

Technical Field

[0001] This utility model relates to the field of hot water tank technology, and in particular to a hot water tank device for high-speed trains with adjustable installation position. Background Technology

[0002] In the operation system of high-speed trains, the hot water tank device is a key component to ensure passengers' drinking water needs and the low-temperature protection of train equipment. Its installation stability, functional adaptability and maintenance convenience directly affect the train's operating efficiency and service quality.

[0003] Currently, the water supply pipelines of the high-speed train's hot water tank system are generally installed using a fixed-point connection structure. That is, the water supply pipes are rigidly connected to the hot water tank body and the train's piping system through pre-set flanges, clips, or welded supports. The installation position is determined during the manufacturing stage and cannot be adjusted according to the actual assembly scenario and usage requirements. Due to the differences in the spatial layout and pipeline routing of different high-speed train models, the fixed-position water supply pipelines are difficult to adapt to diverse installation environments, often resulting in interference between the water supply pipes and other components of the train body. To avoid interference, it is necessary to design additional irregularly shaped adapters or make partial modifications to the train body structure, which not only increases the manufacturing cost but also extends the assembly cycle. Therefore, we propose a high-speed train hot water tank device with an adjustable installation position. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a high-speed train hot water tank device with adjustable installation position. This solves the problem that the current installation of the water supply pipeline of the high-speed train hot water tank device generally adopts a fixed point connection structure, that is, the water supply pipe is rigidly connected to the hot water tank body and the train pipeline system through a preset flange, buckle or welded support. The installation position is determined in the production and manufacturing stage and cannot be adjusted according to the actual assembly scenario and usage requirements. Since the spatial layout and pipeline routing of different models of high-speed trains are different, the fixed position water supply pipeline is difficult to adapt to the diverse installation environment, and the water supply pipe often interferes with other parts of the car body. In order to avoid interference, it is necessary to design special-shaped adapters or make partial modifications to the car body structure, which not only increases the production and manufacturing cost, but also prolongs the assembly cycle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-position high-speed train hot water tank device, comprising:

[0006] The main body of the train's hot water tank is equipped with a position adjustment structure.

[0007] The position adjustment structure includes a spiral plate, a limiting slide plate, a screw, a mounting plate, a fixed seat, and a rotating seat. The spiral plate is fixedly connected to one side of the train's hot water tank body. A limiting groove is opened inside the spiral plate, and the limiting slide plate is slidably connected inside the limiting groove. Multiple through holes are opened on the outer surface of the spiral plate, and all of the multiple through holes are connected to the inside of the limiting groove. A threaded hole is opened on one side of the limiting slide plate, and the screw passes through the inside of the corresponding through hole and is threadedly connected to the inside of the threaded hole. The mounting plate is rotatably connected to the side of the limiting slide plate away from the spiral plate. The fixed seat is bolted to the side of the mounting plate away from the limiting slide plate, and the rotating seat is hinged to the fixed seat.

[0008] Preferably, the position adjustment structure further includes two screws and a connecting plate. The top of the fixed seat and the rotating seat are respectively provided with through holes. The two screws are fixedly connected to the bottom of the connecting plate and are respectively installed inside the corresponding through holes.

[0009] Preferably, anti-slip pads are fixedly connected inside the fixed seat and the rotating seat respectively.

[0010] Preferably, a pressure gauge is installed on the top of the train's hot water tank body.

[0011] Preferably, an inlet pipe is fixedly connected to the side of the train's hot water tank body closest to the spiral plate, and an outlet pipe is fixedly connected to the side of the train's hot water tank body furthest from the inlet pipe.

[0012] Preferably, both the inlet pipe and the outlet pipe are connected to the interior of the train's warm water tank.

[0013] Preferably, an observation window is installed on the side of the train's hot water tank body near the outlet pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This adjustable-position EMU hot water tank device allows for the adjustment of the water supply pipe's installation position. When adjustment is needed, the limiting slide plate is pushed to slide within the limiting groove to the target position. Subsequently, a screw is screwed into the threaded hole through the corresponding through hole to fix the limiting slide plate, achieving initial positioning of the water supply pipe in a certain direction. With the cooperation of the mounting plate, fixed seat, and rotating seat, the water supply pipe can be stably installed. This facilitates flexible adjustment of the water supply pipe's position according to different EMU car body spatial layouts, effectively avoiding interference between the water supply pipe and other car body components. It eliminates the need for additional design of irregularly shaped adapters or partial modifications to the car body structure, reducing manufacturing costs and shortening the assembly cycle.

[0030] Water inlet pipe 5: It is fixedly connected to the side of the EMU hot water tank body 1 near the spiral plate 6 and communicates with the inside of the body. Its main function is to transport cold water from the EMU water supply system to the inside of the EMU hot water tank body 1 to provide a water source for heating the hot water.

[0031] Spiral plate 6: It is fixedly connected to one side of the body 1 of the hot water tank of the train and is the basic installation component of the position adjustment structure; it has a limiting slide groove 8 adapted to the limiting slide plate 9 inside, and multiple through holes 7 connected to the limiting slide groove 8 on the outer surface to provide support for the sliding and fixing of the limiting slide plate 9.

[0032] Through hole 7: It is formed on the outer surface of the spiral plate 6. Multiple through holes 7 are connected to the inside of the limiting slide groove 8. Its function is to provide a passage for the screw 10. When the limiting slide plate 9 slides to the target position, the screw 10 can pass through the corresponding through hole 7 and be screwed into the threaded hole 15 to fix the limiting slide plate 9 on the spiral plate 6.

[0033] Limiting groove 8: It is opened inside the spiral plate 6 and its shape is adapted to the limiting slide plate 9. Its main function is to limit the sliding trajectory of the limiting slide plate 9, prevent the limiting slide plate 9 from deviating from the direction when sliding, ensure that it moves stably along the set path, and provide guidance for the directional positioning of the train's hot water tank body 1.

[0034] Limiting slide plate 9: It is slidably connected inside the limiting slide groove 8, and has a threaded hole 15 on one side that is adapted to the screw 10. The side away from the spiral plate 6 is rotatably connected to the mounting plate 13. Its core function is to adjust the position by sliding in the limiting slide groove 8, so as to drive the mounting plate 13 and subsequent components to move synchronously, provide a preliminary positioning of the hot water tank body 1 of the train in a certain direction, and at the same time provide a rotation mounting base for the mounting plate 13.

[0035] Screw 10: It passes through the through hole 7 on the spiral plate 6 and is threadedly connected to the threaded hole 15 of the limiting slide plate 9. Its function is to firmly fix the limiting slide plate 9, which has slid to the target position, on the spiral plate 6, lock the position of the limiting slide plate 9, and thus fix the initial positioning state of the train's hot water tank body 1.

[0036] Fixed base 11: It is installed on the side of the mounting plate 13 away from the limiting slide plate 9 by bolts. It has a through hole 16 on the top and an anti-slip pad 14 is fixedly connected inside. It is also hinged to the rotating base 12. Its function is to serve as a fixed base for the installation of water supply pipe. It cooperates with the rotating base 12 to form a clamping space for water supply pipe. At the same time, through its connection with the mounting plate 13, it rotates with the mounting plate 13 relative to the limiting slide plate 9 to achieve angle adjustment.

[0037] Rotating seat 12: Hinged on the fixed seat 11, with a through hole 16 on the top and an anti-slip pad 14 fixedly connected inside; its core function is to open and close with the fixed seat 11 by rotating around the hinge axis of the fixed seat 11: when closed, it clamps the water supply pipe together with the fixed seat 11; when open, it facilitates the installation and disassembly of the water supply pipe; at the same time, it can adjust its angle synchronously with the fixed seat 11 to adapt to the installation space of the EMU body;

[0038] Mounting plate 13: Rotatably connected to the side of the limiting slide plate 9 away from the spiral plate 6, and the side away from the limiting slide plate 9 is bolted to the fixing seat 11; its function is to serve as a connecting transition component between the fixing seat 11 and the limiting slide plate 9, and it can rotate relative to the limiting slide plate 9, driving the fixing seat 11 and the rotating seat 12 to rotate synchronously, providing a rotation basis for subsequent angle adjustment;

[0039] Anti-slip pad 14: It is fixedly connected inside the fixed seat 11 and the rotating seat 12 respectively, and the material has a high coefficient of friction. Its function is to increase the friction between the water supply pipe and the clamping parts when the fixed seat 11 and the rotating seat 12 clamp the water supply pipe, to prevent the water supply pipe from sliding due to vibration caused by the operation of the train, and to improve the stability and reliability of the water supply pipe installation.

[0040] Threaded hole 15: It is opened on one side of the limiting slide plate 9 and is compatible with the thread specification of the screw 10. Its function is to provide a threaded connection point for the screw 10. After the screw 10 passes through the through hole 7, it is screwed into the threaded hole 15. The limiting slide plate 9 and the spiral plate 6 are fixed through thread engagement.

[0041] Through hole 2 16: It is opened on the top of the fixed seat 11 and the rotating seat 12 respectively, and is adapted to the diameter of the screw 2 18. Its function is to provide a through channel for the screw 2 18. When the rotating seat 12 closes and clamps the water supply pipe, the screw 2 18 can be inserted into the corresponding through hole 2 16. With the help of nuts and other fasteners, the fixed seat 11 and the rotating seat 12 are firmly connected, locking the clamping state of the water supply pipe.

[0042] Connecting plate 17: The bottom is fixedly connected to two screws 18, which is an integrated installation component of screws 18; its function is to ensure that screws 18 can be accurately inserted into the through holes 16 of the fixed seat 11 and the rotating seat 12 at the same time by simultaneously fixing the two screws 18, so as to provide a unified force carrier for the connection between the fixed seat 11 and the rotating seat 12 and improve the stability of the connection.

[0043] Screw 2 18: Both screws 2 18 are fixedly connected to the bottom of the connecting plate 17, and are respectively provided with through holes 2 16 of the fixed seat 11 and the rotating seat 12; their function is to cooperate with fasteners such as nuts to tightly connect the connecting plate 17, the fixed seat 11 and the rotating seat 12, prevent the rotating seat 12 from accidentally opening during the operation of the train, and ensure that the water supply pipe is firmly clamped.

[0044] Example 1:

[0045] like Figure 1-4 As shown, when it is necessary to adjust the installation position of the water supply pipe, push the limiting slide plate 9 to slide in the limiting slide groove 8 to the target position, then select the corresponding through hole 7, pass the screw 10 through the through hole 7 and screw it into the threaded hole 15. Through the threaded connection between the screw 10 and the threaded hole 15, the limiting slide plate 9 is fixed in the designated position of the spiral plate 6, thereby achieving the initial positioning of the water supply pipe in a certain direction.

[0046] The fixed seat 11 can rotate relative to the limiting slide plate 9 with the mounting plate 13, and the rotating seat 12 can also rotate hinged relative to the fixed seat 11. This allows the angle of the fixed seat 11 to be flexibly adjusted according to the shape and space of the installation part on the train body to better adapt to different installation environments. After the rotating seat 12 is closed and the water supply pipe is installed, the screw 18 at the bottom of the connecting plate 17 is inserted into the through hole 16. The screw 18 is fixed in the through hole 16 by fasteners such as nuts, thereby firmly connecting the fixed seat 11 and the rotating seat 12 and ensuring the stability of the entire position adjustment structure.

[0047] Example 2:

[0048] like Figure 4As shown, the anti-slip pad 14 prevents the water supply pipe from sliding and shifting, ensuring the tightness and accuracy of the connection between the water supply pipe and other pipe components, preventing the water supply pipe from moving, and ensuring that the water supply pipeline system of the entire EMU hot water tank device can continuously and stably provide the EMU with the required water and maintain the normal operation of the EMU's related water-using equipment.

[0049] Furthermore, when using this device, when it is necessary to adjust the installation position of the water supply pipe, push the limiting slide plate 9 to slide in the limiting slide groove 8 to the target position, then select the corresponding through hole 7, pass the screw 10 through the through hole 7 and screw it into the threaded hole 15. Through the threaded connection between the screw 10 and the threaded hole 15, the limiting slide plate 9 is fixed at the designated position of the spiral plate 6, thereby achieving the initial positioning of the water supply pipe in a certain direction.

[0050] The fixed seat 11 can rotate relative to the limiting slide plate 9 with the mounting plate 13, and the rotating seat 12 can also rotate hinged relative to the fixed seat 11. This allows the angle of the fixed seat 11 to be flexibly adjusted according to the shape and space of the installation part on the train body to better adapt to different installation environments. After the rotating seat 12 is closed and the water supply pipe is installed, the screw 18 at the bottom of the connecting plate 17 is inserted into the through hole 16. The screw 18 is fixed in the through hole 16 by fasteners such as nuts, thereby firmly connecting the fixed seat 11 and the rotating seat 12 and ensuring the stability of the entire position adjustment structure.

[0051] The anti-slip pad 14 increases friction to prevent the water supply pipe from sliding due to vibrations caused by the operation of the train during use, further improving the reliability of the installation. A pressure gauge 4 is installed on the top of the train's hot water tank body 1 to monitor the internal pressure of the water tank in real time and ensure that the water tank operates within the normal pressure range. A water inlet pipe 5 is fixedly connected to the side near the spiral plate 6, and a water outlet pipe 2 is fixedly connected to the side away from the water inlet pipe 5. Both the water inlet pipe 5 and the water outlet pipe 2 are connected to the interior of the train's hot water tank body 1. An observation window 3 is installed on the side near the water outlet pipe 2 to facilitate operators to observe the water level and other conditions inside the water tank.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
