Description

Technical Field

[0001] The utility model relates to the field of protective plates, in particular to a protective plate for a sewage discharge pipeline of a high-speed rail vehicle. Background Technique

[0002] With the rapid development of high-speed railways, high-speed rails have become an important choice for people to travel due to their high efficiency, speed, and comfort. During the operation of high-speed rail vehicles, the sewage discharge system plays a crucial role in ensuring the normal operation of the vehicles and environmental hygiene.

[0003] During the use of high-speed rails, the protective plate can protect the sewage discharge pipeline, preventing foreign objects such as flying stones and gravel from hitting the sewage discharge pipeline, causing damage and leakage of the pipeline, thus affecting the normal function of the sewage discharge system, and may also pollute the environment along the railway, and even endanger the safety of train operation.

[0004] The existing protective plates for sewage discharge pipelines of high-speed rail vehicles are not convenient to open and close during operation. When opening the protective plate, it is necessary to pull the protective plate by hand, which is not convenient to open. Moreover, the opened protective plate is hidden inside the high-speed rail, making it inconvenient to see how to close it. Often, it is necessary to reach into the high-speed rail to pull down the protective plate and then push it back to its original position. The pushing-back process may cause the protective plate to get stuck. For this reason, we propose a protective plate for a sewage discharge pipeline of a high-speed rail vehicle. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a protective plate for a sewage discharge pipeline of a high-speed rail vehicle to solve the technical problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A protective plate for a sewage discharge pipeline of a high-speed rail vehicle, including a high-speed rail main body, a sewage discharge pipeline, and a protective plate. A second fixing block is fixedly installed on the side wall of the protective plate, and a third fixing block is slidably installed on the side wall of the protective plate. A first slider is fixedly installed at the bottom end of the third fixing block, and a driven connecting rod is rotatably installed on the outer wall of the first slider. The end of the driven connecting rod is rotatably installed with a driving connecting rod, and a second slider is slidably installed on the outer wall of the driving connecting rod. A spring connecting the protective plate is fixedly installed at the end of the second slider, and a handle is fixedly installed at the end of the second slider. A first sliding groove for the handle to rotate is opened on the outer wall of the protective plate, and a pulling groove is opened on the outer wall of the protective plate. A first fixing block corresponding to the handle is fixedly installed on the side wall of the first sliding groove. A second sliding groove corresponding to the second fixing block is opened on the side wall of the high-speed rail main body, and a support groove corresponding to the third fixing block is opened on the side wall of the high-speed rail main body. Moreover, a support plate for supporting the protective plate is fixedly installed on the side wall of the high-speed rail main body.

[0007] By adopting the above technical solutions, when the high-speed train is in operation, the first fixing block fixes the handle, and the third fixing block fixes the protection plate, which can protect the sewage pipe. When it is necessary to open the protection plate, press the handle, thereby squeezing the spring, causing the second slider to slide, releasing the restriction of the first fixing block on the handle. At this time, rotate the handle, so that the active connecting rod drives the driven connecting rod, thereby driving the first slider and the third fixing block, causing the third fixing block to release the restriction on the protection plate. At this time, the protection plate can be rotated and pushed into the main body of the high-speed train. When it is necessary to close the protection plate, pull out the protection plate, and the support plate will limit the protection plate. Rotate the handle, so that the first slider and the third fixing block slide, thereby restricting the protection plate through the third fixing block. At this time, release the handle, and the spring will reset, causing the first fixing block to fix the handle, accelerating the closing speed of the protection plate and making it more convenient to open and close the protection plate.

[0008] The present invention is further configured such that a plurality of groups of the second fixing block, the third fixing block, the first slider and the support plate are symmetrically installed, and a plurality of groups of second chutes and support grooves are symmetrically formed.

[0009] By adopting the above technical solutions, the structure is made more stable.

[0010] The present invention is further configured such that a plurality of groups of the driven connecting rods are installed in parallel, and a groove for the rotation of the driven connecting rod is formed inside the first slider.

[0011] By adopting the above technical solutions, the driven connecting rod can rotate on the outer wall of the first slider, thereby driving the first slider to slide.

[0012] The present invention is further configured such that the second slider has a rectangular cross-section and the second slider penetrates through the active connecting rod.

[0013] By adopting the above technical solutions, when the handle rotates, it can drive the active connecting rod to rotate.

[0014] The present invention is further configured such that a plurality of groups of guiding grooves corresponding to the handle are symmetrically formed on the outer wall of the first fixing block close to the sewage pipe, and the guiding grooves are designed with an oblique angle.

[0015] By adopting the above technical solutions, the handle can rotate better in the first chute.

[0016] The present invention is further configured such that the first chute is fan-shaped and corresponds to the rotation trajectory of the handle, and pulling grooves are formed on both outer walls of the protection plate.

[0017] By adopting the above technical solutions, the handle can rotate in the first chute for pulling the protection plate.

[0018] The present utility model is further configured such that the second sliding groove corresponds to the third fixing block after being rotated by 90 degrees.

[0019] By adopting the above technical solution, the protection plate can only be pushed into the high-speed rail main body along the second sliding groove after being rotated by 90 degrees.

[0020] The present utility model is further configured such that the distance between the side wall of the support plate and the side wall of the high-speed rail main body corresponds to the thickness of the protection plate, and the side wall of the high-speed rail main body, the outer wall of the handle, and the outer wall of the first fixing block are on the same horizontal plane.

[0021] By adopting the above technical solution, when the protection plate is closed, the support plate can limit the protection plate, so that the wind resistance on the handle and the first fixing block is reduced when the high-speed rail is running.

[0022] In summary, the present utility model mainly has the following beneficial effects:

[0023] The present utility model is provided with a first fixing block, a second fixing block, a driving link, a driven link, a first slider, a third fixing block, a second slider and a spring. When the high-speed rail is in operation, the first fixing block fixes the handle, and the third fixing block fixes the protection plate, which can protect the sewage pipe. When the protection plate needs to be opened, press the handle, thereby compressing the spring, causing the second slider to slide, releasing the restriction of the first fixing block on the handle. At this time, rotate the handle, causing the driving link to drive the driven link, thereby driving the first slider and the third fixing block, causing the third fixing block to release the restriction on the protection plate. At this time, the protection plate can be rotated and pushed into the high-speed rail main body. When the protection plate needs to be closed, pull out the protection plate, and the support plate will limit the protection plate. Rotate the handle, causing the first slider and the third fixing block to slide, thereby restricting the protection plate through the third fixing block.
