Abstract
Description
Technical Field
[0001] This application relates to the field of train water supply equipment, and particularly relates to a water pipe for train water supply. Background Art
[0002] With the rapid development of China's railway transportation, especially the popularization of high-speed rail operation, the water supply demand for passenger trains has increased significantly. During long-distance train travel, it is necessary to replenish water sources for the water storage tanks of each carriage during a short stop at the station to ensure the normal operation of water-using systems such as washrooms and dining cars in the carriage.
[0003] Most of the existing train water supply systems rely on manual operation. The water supply workers need to connect the water supply pipe to the train water injection port and manually control the water flow until the water tank is full. Since the train stop time is strictly limited, the water supply process must be completed efficiently within a short time; otherwise, it will directly affect the on-time departure and subsequent operation of the train.
[0004] The water supply worker needs to drag a relatively long water supply pipe to perform water supply operations on both sides of the train, and each water supply worker is responsible for 3 - 4 carriages. The water supply worker first connects the water supply pipe to the carriage water injection port and then opens the water tap to supply water. During the water supply process, the water pipe is filled with water and the pipe becomes bulky. Especially when the train stop time is short, the working intensity of the worker increases significantly, and frequently dragging the water pipe causes a greater burden on the worker's body and affects the operation efficiency. Content of the Utility Model
[0005] Therefore, this application provides a water pipe for train water supply to solve the problem of the large working intensity of train water supply workers in the prior art.
[0006] To achieve the above object, this application provides the following technical solutions:
[0007] A water pipe for train water supply includes a pipe body connected to a water tap at one end, and a plurality of support rings sleeved on the pipe body. The plurality of support rings are uniformly spaced along the length direction of the pipe body, and one side of the support ring away from the pipe body is formed into an arc surface for abuting against the ground along its circumferential direction.
[0008] Optionally, a plurality of balls are uniformly connected along the circumferential direction of the arc surface.
[0009] Optionally, a plurality of ball grooves for embedding the balls are formed in the arc surface. The plurality of ball grooves correspond to the plurality of balls one by one. The radius of the ball groove is greater than the radius of the ball, the radius of the notch of the ball groove is less than the radius of the ball, and the bottom of the ball groove is formed into a limiting surface so that when the ball abuts against the limiting surface, the ball partially extends out of the notch of the ball groove.
[0010] Optionally, a plurality of limiting annular grooves for embedding the support rings are formed in the pipe body, the arc surface extends out of the limiting annular grooves, and the plurality of limiting annular grooves correspond to the plurality of support rings one by one.
[0011] Optionally, a fluorescent layer is coated on the arc surface of the support ring.
[0012] Compared with the prior art, the present application has at least the following beneficial effects:
[0013] A plurality of support rings are sleeved on the pipe body (water pipe) at uniform intervals along the length direction of the pipe body. When the water supply worker drags the pipe body, these support rings support part of the pipe body on the ground. Through the arc-shaped design of the support rings, the surface area in contact with the ground is small, so as to effectively reduce the friction between the pipe body and the ground. The arc surface of the support ring enables the water supply worker to drag the pipe body without having to overcome the resistance caused by the large-area contact between the pipe body and the ground. Compared with directly dragging the water pipe in the prior art, the physical exertion of the water supply worker during the operation is greatly reduced, and at the same time, the abrasion caused by the friction between the water pipe and the ground is also reduced, thereby prolonging the service life of the water pipe.

[0022] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0023] In the description of the present application: Unless otherwise specified, the meaning of "a plurality of" is two or more. Expressions such as "including", "comprising", "having" also mean "not limited to" (certain units, components, materials, steps, etc.); among them, Figure 1 is a partial structure of a water pipe.
[0024] Refer to Figure 1-5 , the present application discloses a water pipe for train water supply, including a pipe body 1 connected to a hydrant at one end, and a plurality of support rings 2 sleeved on the pipe body 1. The plurality of support rings 2 are evenly spaced along the length direction of the pipe body 1, and the side of the support ring 2 away from the pipe body 1 is formed into an arc surface 21 for abutting against the ground along its circumferential direction.
[0025] The plurality of support rings 2 are evenly sleeved on the pipe body 1 along the length direction of the pipe body 1 (water pipe). When the water supply worker drags the pipe body 1, these support rings 2 partially support the pipe body 1 on the ground. Through the arc design of the support ring 2, the surface area in contact with the ground is small, thereby effectively reducing the friction between the pipe body 1 and the ground. The arc surface 21 of the support ring 2 enables the water supply worker to drag the pipe body 1 without having to overcome the resistance caused by the large-area contact between the pipe body 1 and the ground. Compared with directly dragging the water pipe in the prior art, the physical exertion of the water supply worker during the operation is greatly reduced, and at the same time, the wear caused by the friction between the water pipe and the ground is also reduced, thereby extending the service life of the water pipe.
[0026] In some embodiments, the support ring 2 can be made of a light and wear-resistant material to further reduce the weight and friction of the pipe body 1. For example, the support ring 2 can be made of high-strength plastic, such as polyethylene or polypropylene. In addition, aluminum alloy can also be selected.
[0027] A plurality of balls 22 are evenly connected along the circumferential direction of the arc surface 21.
[0028] The plurality of balls 22 are evenly connected to the arc surface 21 of the support ring 2, further reducing the friction between the support ring 2 and the ground. Since the balls 22 have the characteristics of rolling friction, compared with traditional sliding friction, the resistance is smaller, further reducing the labor intensity of the water supply worker.
[0029] The arc surface 21 is provided with a plurality of ball grooves 23 for embedding balls 22. The plurality of ball grooves 23 correspond to the plurality of balls 22 one by one. The radius of the ball groove 23 is greater than the radius of the ball 22, the radius of the notch of the ball groove 23 is less than the radius of the ball 22, and the bottom of the ball groove 23 forms a limiting surface 231, so that when the ball 22 abuts against the limiting surface 231, a part of the ball 22 protrudes out of the notch of the ball groove 23.
[0030] The radius of the ball groove 23 is greater than the radius of the ball 22, which enables the ball 22 to roll freely in the ball groove 23. However, since the radius of the notch of the ball groove 23 is less than the radius of the ball 22, the ball 22 will not come out of the ball groove 23. The limiting surface 231 at the bottom of the ball groove 23 plays a role in restricting the movement range of the ball 22, so that the ball 22 always partially protrudes out of the notch of the ball groove 23 during rolling and keeps in contact with the ground.
[0031] In some embodiments, the plurality of balls 22 can also be fixedly connected to the arc surface 21.
[0032] The pipe body 1 is provided with a plurality of limiting ring grooves 11 for embedding the support rings 2. The arc surface 21 protrudes out of the limiting ring grooves 11. The plurality of limiting ring grooves 11 correspond to the plurality of support rings 2 one by one.
[0033] The design of the limiting ring grooves 11 enables the support rings 2 to be stably embedded on the pipe body 1, effectively preventing the support rings 2 from moving along the length direction of the pipe body 1 and ensuring that the support rings 2 always remain in a predetermined position. Through the partial embedding of the support rings 2 by the limiting ring grooves 11, the main part of the support rings 2 is buried inside the pipe body 1, and only the arc surface 21 part protrudes out of the limiting ring grooves 11. In this way, the external protrusion of the support rings 2 is reduced, and the influence on the winding or storage of the water pipe due to the large-area protrusion of the support rings 2 from the outer wall of the pipe body 1 is avoided.
[0034] In some embodiments, the depth of the limiting ring grooves 11 can be half of the wall thickness of the pipe body 1 to ensure that the support rings 2 are stably embedded in the grooves while maintaining the structural strength of the pipe body 1. The support rings 2 can be firmly connected in the limiting ring grooves 11 by gluing or other fixing methods.
[0035] The support ring 2 is coated with a fluorescent layer on the arc surface 21.
[0036] The arc surface 21 of the support ring 2 is coated with a fluorescent layer, enabling it to emit fluorescence at night or in a dim environment, which helps the water supply workers to more easily identify the position of the water pipe.
[0037] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written out should also be regarded as within the scope described in this specification.
[0038] In the foregoing, the present application has been described in a relatively specific and detailed manner through general descriptions and specific embodiments. It should be understood that based on the technical concept of the present application, several conventional adjustments or further innovations can also be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
