Abstract
Description
Technical Field
[0001] This utility model relates to the field of warm water tank technology, specifically a warm water tank for railway use. Background Technology
[0002] In railway transportation, hot water tanks on trains are used to store and supply hot water to meet the drinking water needs of passengers and crew. Traditional railway hot water tanks typically use a fixed installation structure, directly welded or bolted to the car body.
[0003] The existing patent (authorization announcement number: CN222388046U) discloses a roof-mounted water tank. The key technical points of the solution are: by setting up a baffle in the water tank, the water flow distance is reduced and the water impact effect is reduced. By setting a buffer port on the baffle, the water flow is guided and the impact effect of the water during the flow is reduced, which effectively reduces the vibration effect of the water stored in the vehicle during driving. It can further increase the volume to store more water. At the same time, setting up multiple baffles can better separate the stored water and reduce the water flow distance.
[0004] However, the above technical solutions still have certain defects. Due to the vibration and impact generated during train operation, long-term use may cause the water tank connection to loosen, or even cause damage or leakage to the water tank, affecting the safety of use. Therefore, a railway hot water tank is proposed. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0031] In one embodiment, such as Figures 1-6 As shown, a railway hot water tank includes a fixing plate 1, a tank body 4 is installed on the side of the fixing plate 1, a connecting pipe 3 is installed through the inside of the tank body 4, and a buffer assembly 2 for buffering the water tank is provided on the side of the fixing plate 1 near the tank body 4.
[0032] In this embodiment, by adding a buffer component 2, which is set between the fixed plate 1 and the housing 4, the vibration and impact force during train operation can be effectively absorbed, and the rigid collision between the housing 4 and the fixed plate 1 can be reduced. The housing 4 is provided with a locking component 45, so that the control box 41 and the cover plate 42 can be separated, which facilitates the maintenance or replacement of water tank components.
[0033] In one embodiment, such as Figure 2 and Figure 3As shown, the buffer assembly 2 includes a fixing ring 24 fixedly installed on the side of the fixing plate 1 near the housing 4. A bidirectional screw 21 is rotatably connected to the center of the fixing ring 24. Two sets of threads with opposite directions are respectively provided at both ends of the bidirectional screw 21. Two sets of clamping members 22 are respectively provided on the two sets of threads. A limit rod 23 is provided through the clamping member 22. A handle 25 is provided at the bottom end of the bidirectional screw 21. By rotating the handle 25 to drive the bidirectional screw 21, the clamping members 22 on the two sets of opposite threads can be controlled to move towards each other synchronously, realizing the dynamic adjustment of the clamping force of the housing 4. This can ensure the fixing strength and reserve buffer space. At the same time, the movement trajectory of the clamping member 22 is constrained by the limit rod 23. The rotational connection structure between the fixing ring 24 and the bidirectional screw 21 has a self-locking characteristic and will not loosen spontaneously under vibration.
[0034] In one embodiment, such as Figure 2 As shown, the bottom of the clamping member 22 is provided with an elastic pad, and two sets of the buffer assembly 2 are mirror-arranged along the center line of the short side of the fixed plate 1; the elastic pad serves as a primary buffer to directly absorb high-frequency micro-amplitude vibrations, and the mirror arrangement forms a couple structure, so that the box 4 generates a self-balancing torque when it is subjected to vibration.
[0035] In one embodiment, such as Figure 4 and Figure 5 As shown, the housing 4 consists of a control box 41, a cover plate 42, a connector 43, a locking component 44, and a locking assembly 45. The top of the control box 41 is fixedly connected to the connector 43, and the side of the cover plate 42 away from the control box 41 is fixedly connected to the locking component 44. The locking component 44 and the connector 43 lock together, and the locking assembly 45 is disposed through the surface of the cover plate 42. The cover plate 42 is also provided with an observation window for observing the inside of the control box 41. The insertion structure of the locking component 44 and the connector 43 forms a mechanical seal, which shortens the disassembly time between the cover plate 42 and the control box 41. At the same time, the situation inside the warm water tank can be observed through the observation window.
[0036] In one embodiment, such as Figure 5 and Figure 6As shown, the engaging assembly 45 includes a fixed circular plate 451 fixedly installed on the side of the cover plate 42 away from the control box 41. A limit post 453 is provided at the center of the fixed circular plate 451. An engaging plate 452 is provided at one end of the limit post 453 away from the fixed circular plate 451. A connecting rod 454 is also provided at the center of the limit post 453. A nut 455 is provided at one end of the connecting rod 454 away from the limit post 453. Two sets of nuts 455 are provided. The thread is installed on the threaded post, and an elastic element 456 is fixedly installed on the threaded post; the opposing movement of the double nuts 455 on the threaded post can precisely control the pressing force of the locking plate 452, and the elastic element 456 provides continuous compensation force. By rotating the fixed circular plate 451, the elastic element 456 is driven to rotate through the connecting rod 454, so that the long side of the elastic element 456 engages with the control box 41. By rotating the connecting rod 454 so that the long side of the elastic element 456 is perpendicular to the side of the cover plate 42, the cover plate 42 can be disassembled.
[0037] In one embodiment, such as Figure 6 As shown, four sets of engaging components 45 are provided, all of which are installed through the cover plate 42. The connecting rod 454 sequentially passes through the fixed circular plate 451, the engaging plate 452, and the limiting post 453. The end of the connecting rod 454 away from the nut 455 is connected to a rotating component. The rotating component protrudes from the outer surface of the cover plate 42. The elastic component 456 is made of elastic material, and its two ends abut against the end of the threaded post and the nut 455, respectively. The four sets of engaging components 45 are symmetrically distributed at 90°. The rotating component protruding from the cover plate 42 rotates simultaneously. The rotating component is connected to the connecting rod 454 by a T-slot. By rotating the rotating component, the elastic component 456 is driven to rotate. By tightening the position between the two sets of nuts 455, the compression of the elastic component 456 is adjusted, thereby achieving precise control of the preload.
[0038] The above embodiment discloses a railway hot water tank, wherein by setting a buffer component 2, the bidirectional screw 21 is driven by rotating the handle 25, and the clamping parts 22 on the two sets of reverse threads can be controlled to move in opposite directions simultaneously, so as to realize the dynamic adjustment of the clamping force of the tank body 4. The buffer pad at the bottom of the clamping part 22 buffers the tank body 4, reducing the impact of vibration on the tank body 4. At the same time, by rotating the rotating part, the elastic part 456 is driven to rotate, so as to engage the control box 41, and at the same time provide a certain buffering effect to prevent the cover plate 42 from being rigidly engaged with the control box 41, which is prone to vibration damage.
[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
