Description

Technical Field

[0001] This utility model relates to the field of railway vehicle sewage discharge technology, specifically a special sewage discharge pipe for railway vehicles. Background Technology

[0002] Railway vehicles are the means of transporting passengers and goods used by the railway transportation department. The toilets on railway vehicles are mainly divided into two types: direct discharge type and pressure type. The discharge pipe is the last gate of the pressure type toilet, which discharges the waste that has been treated by the filter to the outside of the train.

[0003] The prior art patent document CN220842526U provides a train sewage system for preventing backflow of air. The system includes a train floor plate and utilizes a design of a squatting position, a straight discharge pipe, connectors, and an anti-backflow mechanism. By inserting an installation ring into a movable groove, a locking block is pushed into a second insertion hole by a pushing spring, thus installing a membrane flap. When waste flows with the water, it directly compresses the membrane flap, causing it to open and discharge the waste. When no waste is being discharged, the membrane flaps close together. Due to the arc-shaped structure of the membrane flaps, gas entering from the bottom of the discharge pipe only pushes the membrane flaps tightly closed, preventing them from opening and thus preventing backflow of air into the toilet.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, the sewage inside the sewage pipe flows naturally and is easy to remain on the inner wall of the sewage pipe, causing pollution and affecting its service life; secondly, the length of the sewage pipe is fixed during the use of the device, which is not convenient to adapt to the different needs of different railway vehicles and needs to be improved. In view of this, we propose a sewage pipe for railway vehicles. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the issues mentioned above, such as the natural flow of sewage inside the sewage pipe leading to residue buildup on the inner wall and reduced service life, and the fixed length of the sewage pipe making it unsuitable for adapting to the different needs of various railway vehicles, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a special sewage pipe for railway vehicles, which facilitates faster sewage flow, makes cleaning easier, avoids dirt residue, prevents pollution, extends service life, and allows for easy splicing and length adjustment of the sewage pipe, making it suitable for different needs of different railway vehicles.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A special sewage pipe for railway vehicles includes a sewage pipe with flange rings at both ends of its outer circumference. Multiple connection holes are formed on the sidewalls of both flange rings. An anti-scaling component is provided at one end of the inner circumference of the sewage pipe. The anti-scaling component includes an annular chamber. A fixing cover is provided on the outer circumference of the sewage pipe. A motor is mounted on the sidewall of the fixing cover. A first gear is provided at the output end of the motor, meshing with a second gear. The second gear meshes with a gear ring. A fixing ring located on the sidewall of the inner cavity of the annular chamber is rotatably connected to the inner wall of the gear ring. An annular plate is provided on the sidewall of the gear ring, with multiple nozzles on its sidewall. An air supply pipe is provided on the sidewall of the annular chamber. An air compressor is located on the outer circumference of the sewage pipe at the other end of the air supply pipe. A splicing assembly is provided on the end face of the sewage pipe. The motor and air compressor are electrically connected to an external power source. The motor drives the first gear to rotate, causing the annular plate to rotate the nozzles, thereby causing compressed air to be spirally ejected, improving the sewage discharge effect.

[0012] In a preferred embodiment of this utility model for a special sewage pipe for railway vehicles, the splicing assembly includes multiple positioning blocks. Each positioning block has a slot on one side wall, and the other end of the sewage pipe has multiple positioning grooves. Each positioning groove has a spring inside its side wall, and a locking block is located at the other end of each spring. Both ends of the sewage pipe have pads. The locking blocks prevent the positioning blocks from detaching, thus avoiding loosening of the flange ring during bolt installation and ensuring a proper seal.

[0013] As a preferred embodiment of the railway vehicle-specific sewage pipe of this utility model, the top of the annular compartment has a notch, and the inner circumferential wall of the second gear is rotatably connected to a pin located on the side wall of the inner cavity of the fixed cover.

[0014] In a preferred embodiment of the railway vehicle-specific sewage pipe of this utility model, the thickness of the fixing ring is less than the thickness of the inner cavity of the annular compartment, and the plurality of nozzles are all inclined toward the inner circumference of the sewage pipe.

[0015] As a preferred embodiment of the special sewage pipe for railway vehicles of this utility model, the air compressor is a dual-stage permanent magnet variable frequency air compressor, and a small hole silencer is provided at the interface between the air compressor and the air supply pipe.

[0016] In a preferred embodiment of the railway vehicle-specific sewage pipe of this utility model, the positioning blocks are arranged in a ring array, and the size and position of the positioning blocks match the size and position of the positioning grooves.

[0017] In a preferred embodiment of this utility model for a special sewage pipe for railway vehicles, the size and position of the slot match the size and position of the block, and the material of the pad is fluororubber. The elasticity of the fluororubber pad facilitates the compression deformation of the two pads to ensure a tight fit and improves sealing.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of railway vehicle-specific sewage pipe uses an air compressor to deliver compressed air from the air supply pipe to the annular chamber. The compressed air is then sprayed out through nozzles to clean the dirt adhering to the outer circumference of the sewage pipe, thus accelerating the flow rate and preventing scale buildup that could affect its service life. By turning on the motor, the first gear rotates, which in turn rotates the second gear, causing the gears to rotate around the fixed ring. This, in turn, causes the ring plate to rotate, which in turn rotates multiple nozzles, making it easier to evenly spray compressed air onto the outer circumference of the sewage pipe, resulting in more thorough sewage discharge.

[0021] This type of railway vehicle-specific sewage pipe uses a positioning block inserted into a positioning groove to splice two adjacent sewage pipes. The positioning block squeezes the locking block, causing the locking block to move outward. The spring's rebound force causes the locking block to move inward and engage the locking groove, thus ensuring a stable splicing of adjacent sewage pipes. It is convenient to adjust the length of the sewage pipe to meet different needs. A gasket plate improves the sealing performance to prevent sewage overflow, and a flange ring secures the connection between adjacent sewage pipes. Attached Figure Description

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a special sewage pipe for railway vehicles, including:

[0035] Please see Figures 1-5 This embodiment of a railway vehicle-specific sewage pipe includes a sewage pipe 1. Flange rings 2 are welded to both ends of the outer circumference of the sewage pipe 1. Multiple connection holes 3 are provided on the sidewalls of both flange rings 2. An anti-scaling component 4 is fixedly installed at one end of the inner circumference of the sewage pipe 1. The anti-scaling component 4 includes an annular chamber 401. A fixing cover 402 is welded to the outer circumference of the sewage pipe 1. A motor 403 is fixedly installed on the sidewall of the fixing cover 402. A first gear 404 is fixedly installed at the output end of the motor 403. The first gear 404 meshes with a second gear 405. The second gear 405 meshes with a gear ring 406. A fixing ring 407 located on the sidewall of the inner cavity of the annular chamber 401 is rotatably connected to the inner circumference of the gear ring 406. An annular plate 408 is fixedly installed on the sidewall of the gear ring 406. Multiple nozzles 409 are fixedly installed on the sidewall of the annular chamber 401. An air supply pipe 410 is fixedly installed, and an air compressor 411 is fixedly installed at the other end of the air supply pipe 410 on the outer circumference of the sewage pipe 1. A splicing assembly 5 is fixedly installed on the end face of the sewage pipe 1. The motor 403 and the air compressor 411 are electrically connected to an external power source. By turning on the air compressor 411, compressed air is driven to be transported from the air supply pipe 410 to the annular chamber 401. The air is sprayed out through the nozzle 409 to clean the dirt attached to the outer circumference of the sewage pipe 1, thereby accelerating the flow rate and preventing the accumulation of scale that affects the service life. By turning on the motor 403, the first gear 404 is driven to rotate, thereby causing the second gear 405 to rotate and drive the gear ring 406 to rotate around the fixed ring 407. This causes the ring plate 408 to rotate and drive multiple nozzles 409 to rotate, so that the compressed air is evenly sprayed onto the outer circumference of the sewage pipe 1, making the sewage discharge more thorough.

[0036] It is worth noting that, in order to facilitate the adjustment of the length of the sewage pipe 1 to meet different needs, the splicing component 5 specifically includes multiple positioning blocks 501. Each of the multiple positioning blocks 501 has a slot 502 on both sides of its side wall, and multiple positioning grooves 503 are provided on the other side wall of the sewage pipe 1. Springs 504 are fixed in the inner cavity of both sides of the multiple positioning grooves 503, and a locking block 505 is fixed in the other end of the springs 504. Both ends of the sewage pipe 1 are fixed with pads 506. The positioning blocks 501 are inserted into the positioning grooves 503 to splice two adjacent sewage pipes 1. The positioning blocks 501 squeeze the locking blocks 505, causing the locking blocks 505 to move outward. The rebound force of the springs 504 causes the locking blocks 505 to move inward to engage with the slots 502, thereby making the adjacent sewage pipes 1 stably spliced. This facilitates the adjustment of the length of the sewage pipe 1 to meet different needs. The pads 506 improve the sealing performance to prevent sewage overflow, and the flange rings 2 securely connect the adjacent sewage pipes 1.

[0037] Next, in order to prevent the second gear 405 from being obstructed from meshing, specifically, a notch is opened at the top of the annular compartment 401, and a pin located on the inner wall of the fixed cover 402 is rotatably connected to the inner circumference of the second gear 405. The notch facilitates the accommodation of the second gear 405, making it convenient for the second gear 405 to mesh and transmit power with the gear ring 406, and the pin prevents the second gear 405 from falling off.

[0038] Meanwhile, in order to facilitate the impact of dirt accumulated on the inner circumference of the drain pipe 1, specifically, the thickness of the fixing ring 407 is less than the thickness of the inner cavity of the annular chamber 401, and multiple nozzles 409 are inclined towards the inner circumference of the drain pipe 1. By using the fixing ring 407, which is less thick than the inner cavity of the annular chamber 401, the fixing ring 407 is prevented from being blocked and affecting the delivery of compressed gas. By using the nozzles 409, which are inclined towards the inner circumference of the drain pipe 1, it is easy to spray compressed gas towards the inner circumference of the drain pipe 1 to impact the dirt.

[0039] Furthermore, in order to save costs, specifically, the air compressor 411 is a dual-stage permanent magnet variable frequency air compressor. A small hole silencer is installed at the interface between the air compressor 411 and the air supply pipe 410. The air compressor 411 of the dual-stage permanent magnet variable frequency air compressor improves the energy-saving effect of the air compressor 411, and the small hole silencer reduces noise to prevent it from affecting passengers on railway vehicles.

[0040] It is worth noting that, in order to make the positioning of adjacent sewage pipes 1 more convenient when splicing, the positioning blocks 501 are arranged in a ring array. The size and position of the positioning blocks 501 match the size and position of the positioning grooves 503. By distributing the positioning blocks 501 in a ring array that matches the size and position of the positioning grooves 503, it is convenient to quickly position the adjacent sewage pipes 1 when splicing.

[0041] Finally, to prevent sewage corrosion from affecting the sealing performance, the size and position of the slot 502 are matched with the size and position of the block 505, and the material of the pad 506 is fluororubber. The slot 502, which matches the size and position of the block 505, makes it easier to make the splicing of adjacent sewage pipes 1 more stable. The fluororubber pad 506 improves the corrosion resistance and avoids sewage corrosion from affecting the sealing effect.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0043] The device or equipment models mentioned in this article may be as follows:

[0044] Motor 403: Y90S-2;

[0045] Air compressor 411: SA55A / W.

[0046] Combination Figures 1-5 The specific usage process of a railway vehicle-specific sewage pipe according to this embodiment is as follows:

[0047] 1. According to the actual use, start the air compressor 411 to drive compressed air to be delivered from the air pipe 410 to the annular chamber 401. The compressed air is sprayed out from the nozzle 409 to accelerate the flow rate and clean the dirt attached to the outer wall of the circumference of the drain pipe 1. Start the motor 403 to make the first gear 404 rotate and drive the second gear 405 to rotate, thereby causing the gear ring 406 to drive the multiple nozzles 409 on the side wall of the ring plate 408 to rotate, so that the compressed air is evenly sprayed to the outer wall of the circumference of the drain pipe 1.

[0048] 2: Positioning block 501 is inserted into positioning groove 503 to splice two adjacent sewage pipes 1. Positioning block 501 squeezes the locking block 505 and drives the locking block 505 to move outward. The rebound force of spring 504 drives the locking block 505 to move inward to engage the locking groove 502. The pad 506 fits to prevent sewage from overflowing. The bolt is screwed into the connecting hole 3 to splice the flange ring 2.

[0049] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
