Description

Technical Field

[0001] This utility model relates to the technical field of railway vehicle types or vehicle body components, and in particular to a rapid sewage collection device for high-speed trains. Background Technology

[0002] In modern buildings, bathroom facilities are an indispensable and important component. The perfection and reliability of their functions directly affect people's quality of life. As the core components of the bathroom system, the connection between the toilet and the water tank is crucial. It not only concerns the smooth discharge of sewage, but also involves the sealing, durability and ease of installation and maintenance of the entire system.

[0003] Early sanitary facilities were relatively simple, and the connection between the toilet and the water tank was also quite basic. In the early stages of building development, people's requirements for sanitary facilities were mainly focused on meeting basic functional needs. Pipe connections were mostly straightforward, using simple flange connections. However, with the acceleration of urbanization and the improvement of people's living standards, flange connections are a more advanced method. This method involves fixing two flanges to the ends of two pipes respectively, then connecting the flanges together with bolts, and placing a gasket in the middle to achieve a seal. This connection method has good sealing performance, but the structure of flange connections is more complex, requiring more components such as flanges, bolts, nuts, and gaskets. This not only increases material costs but also makes the installation process more cumbersome, requiring more time and effort. At the same time, flange connections have high requirements for the installation accuracy of the pipes. If the pipe axes do not coincide or the flange faces are not parallel, the gasket will be subjected to uneven force, thus affecting the sealing effect. 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 rapid sewage collection device for high-speed trains. This device can solve the problem that the structure of flange connection is relatively complex, requiring many parts, such as flanges, bolts, nuts, and gaskets. This not only increases material costs, but also makes the installation process more cumbersome, requiring more time and effort. At the same time, flange connection requires high precision in pipe installation. If the pipe axis does not coincide or the flange face is not parallel, it will cause uneven stress on the gasket, thus affecting the sealing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid sewage collection device for high-speed trains, comprising a collection device, a vacuum generator, a cover assembly, a water tank, and a connecting pipe, wherein clamp assemblies are provided at both ends of the connecting pipe; The clamp assembly includes an upper clamp and a lower clamp. The inner walls of both the upper and lower clamps are arc-shaped. Both ends of the connecting pipe are equipped with sealing rings. Protective components are fixedly installed on the inner walls of both the upper and lower clamps. When both protective components are flat protective pads, two protruding plates are fixedly connected to the outer walls of both the upper and lower clamps. Positioning rods are fixedly installed on the lower surfaces of the two protruding plates on the upper clamp. The lower clamp has two positioning rod grooves on the outer walls of the two protruding plates, and bolt grooves on the outer walls of the four protruding plates. The upper and lower clamps are fitted onto the outer wall of one end of the connecting pipe. Two fixing bolts are slidably installed inside the two bolt grooves on the upper clamp. The two clamp assemblies are installed at both ends of the connecting pipe.

[0006] Preferably, the upper clamp is quickly positioned with the lower clamp by four positioning rods cooperating with corresponding positioning rod grooves.

[0007] Preferably, the inner walls of both protective components are in contact with the outer wall of one end of the connecting pipe.

[0008] Preferably, the upper clamp is fixedly connected to the lower clamp by four fixing bolts engaging with two bolt grooves on the lower clamp.

[0009] Preferably, the cover assembly is installed on the upper surface of the toilet bowl, and a second connector is fixedly installed on the left outer wall of the toilet bowl.

[0011] Preferably, the suction end of the vacuum generator is connected to the rear drain pipe of the toilet via a connecting pipe, and the end of the connecting pipe near the toilet is fixedly connected to the second connector via the upper and lower clamps in the clamp assembly.

[0012] Preferably, a first connector is installed on the outer wall of the right side of the water tank, and the outer wall of the end of the connecting pipe away from the toilet is slidably connected to the inside of the first connector.

[0013] Preferably, the sewage discharge end of the vacuum generator is connected to an external collection tank via a connecting pipe, and the end of the connecting pipe away from the toilet is fixedly connected to the water tank by the upper and lower clamps in the clamp assembly.

[0014] Preferably, when all four protective components are arrayed groove-type protective pads, the inner walls of the four arrayed groove-type protective pads are in contact with the two ends of the corresponding connecting pipes and the outer walls of the first connector and the second connector, respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The rapid sewage collection device of this high-speed train consists of only a few parts, such as an upper clamp, a lower clamp, a protruding plate, a positioning rod, and fixing bolts, through the clamp assembly.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Example 1: Reference Figure 1-4 Standard fixing of flat protective pads In daily operation and maintenance of high-speed trains, when it is necessary to connect the toilet 1 and the water tank 4, a flat protective pad is used as a protective component 11. First, the sealing rings 10 are put on both ends of the connecting pipe 9. Then, the upper clamp 6 and the lower clamp 7 are quickly positioned at one end of the connecting pipe 9 through the positioning rod and the positioning rod groove 12, so that the inner wall of the flat protective pad contacts the outer wall of the connecting pipe 9. Next, the fixing bolt 15 is passed through the bolt groove 13 and tightened to fix one end of the connecting pipe 9 on the second connector 14. The other end of the connecting pipe 9 is fixed on the first connector 5 of the water tank 4 in the same way. This method is suitable for normal working conditions, providing a stable sealing and fixing effect, and preventing the connecting pipe from loosening and causing sewage leakage. Example 2: Reference Figure 5 Arrayed groove-shaped protective pads enhance sealing When high-speed trains need to run in cold regions, temperature changes may cause pipes to shrink, which will reduce the sealing effect of ordinary flat protective pads. In this case, the protective component 11 is replaced with array groove-type protective pads 16. During installation, the inner walls of the four array groove-type protective pads 16 are tightly fitted to the two ends of the corresponding connecting pipe 9, the outer walls of the first connector 5 and the second connector 14. The array groove structure increases the contact area, which can better adapt to the small deformation caused by temperature changes and maintain good sealing performance in low-temperature environments, effectively preventing the sewage system from malfunctioning due to sealing failure.

[0023] Furthermore, when using this device, when the device is started, the vacuum generator 2 extracts air from inside the toilet bowl 1 through the connecting pipe, creating a negative pressure environment inside the toilet bowl 1. At this time, the cover assembly 3 is in the closed state, ensuring the airtightness of the inside of the toilet bowl 1. When sewage needs to be discharged, the negative pressure generated by the vacuum generator 2 draws the sewage in the toilet bowl 1 through the rear sewage pipe, and transports it to the external collection tank through the sewage discharge end of the vacuum generator 2 to complete the sewage discharge. The water tank 4 provides flushing water to the toilet bowl 1 through the connecting pipe 9. Its water flow path relies on the clamp assemblies at both ends of the connecting pipe 9 to achieve a sealed connection. When the water tank 4 supplies water, the water flows through the first connector 5 into the connecting pipe 9, and flows into the toilet bowl 1 through the second connector 14 to complete the flushing action. During this process, the sealing rings 10 at both ends of the connecting pipe 9 and the first connector 5, The inner wall of the second connector 14 is in close contact with the clamping force of the upper clamp 6 and the lower clamp 7 to form a double seal to prevent water leakage. Then, the quick positioning function of the clamp assembly (through the positioning rod and the positioning rod groove 12) ensures the coaxiality of the connecting pipe 9 with the first connector 5 and the second connector 14, avoiding sealing failure due to installation deviation. When the fixing bolt 15 slides along the bolt groove 13, the clamping force can be finely adjusted to ensure the connection strength and avoid excessive compression that could deform the sealing ring 10 or the connecting pipe 9. When the protective component 11 is an array groove-type protective pad 16, its groove structure can further disperse the clamping force of the clamp assembly, making the contact stress between the first connector 5, the second connector 14 and the connecting pipe 9 more uniform. This is especially suitable for the vibration environment during train operation and reduces the risk of loosening after long-term use.

[0024] The clamp assembly consists of only a few parts, such as the upper clamp 6, the lower clamp 7, the protruding plate 8, the positioning rod, and the fixing bolt 15, which greatly reduces the types and quantities of required parts. This simplification not only reduces material procurement costs but also reduces production and processing steps, which helps to improve overall production efficiency. At the same time, during installation, there is no need for complicated pre-treatment procedures such as flange welding or thread processing on the pipeline. Simply insert the two ends of the connecting pipe 9 into the first connector 5 and the second connector 14 respectively, and quickly position them by the positioning rod of the upper clamp 6 and the positioning rod groove 12 of the lower clamp 7. Then, the fixing bolt 15 is slid along the bolt groove 13 and tightened to complete the fixation. The entire installation process is simple to operate, significantly shortens the installation time, and reduces labor costs.

[0025] Structural Description: Toilet Collector 1 is the core sewage discharge component of the device. The upper surface is equipped with a cover plate assembly 3, and the left outer wall is fixed with a second connector 14. Its interior is a hollow cavity used to temporarily store sewage. The rear end is connected to the suction end of the vacuum generator 2 through a sewage discharge pipe, and sewage is quickly discharged by relying on vacuum negative pressure.

[0026] Vacuum generator 2: Vacuum generator 2 is a negative pressure power source. It is connected to the rear sewage pipe (suction end) of toilet 1 and the external collection box (sewage end) through connecting pipes. When working, it draws air out of toilet 1 to form negative pressure, driving the sewage from toilet 1 to the external collection box, so as to achieve sewage discharge without residue.

[0027] Cover assembly 3: Cover assembly 3 is installed on the upper surface of toilet 1 and is used to close or open the use port of toilet 1. When closed, it ensures the airtightness of the inside of toilet 1 and ensures that the vacuum negative pressure is effectively formed. When open, it is used by passengers. Its structural design must meet the stability and safety requirements of the train operation.

[0028] Water tank 4: Water tank 4 is the water storage component of the flushing system. The first connector 5 is installed on the outer wall of the right side and is connected to the second connector 14 of the toilet 1 through the connecting pipe 9. The flushing water stored inside flows into the toilet 1 through the connecting pipe 9 by gravity or pressure to complete the sewage flushing action.

[0029] First connector 5 and second connector 14: First connector 5 is fixed to the outer right side of water tank 4, and second connector 14 is fixed to the outer left side of toilet 1. Both are tubular structures, and their inner walls are in close contact with the sealing rings 10 at both ends of connecting pipe 9. They are transitional connectors between connecting pipe 9 and water tank 4 and toilet 1.

[0030] Clamp assembly: (Upper clamp 6, Lower clamp 7) The clamp assembly is the core fixing component at both ends of the connecting pipe 9. It consists of upper clamp 6 and lower clamp 7. The inner walls of both are arc-shaped, which fits the outer wall contour of the connecting pipe 9. Upper clamp 6 and lower clamp 7 are connected by fixing bolts 15 on the protruding plate 8. When clamped, the connecting pipe 9 is fixed on the first connector 5 and the second connector 14 respectively, realizing the rapid assembly and sealing of the pipeline.

[0031] The convex plate 8 and the positioning structure: Two convex plates 8 are fixed to the outer walls of the upper clamp 6 and the lower clamp 7. The lower surface of the convex plate 8 of the upper clamp 6 is provided with a positioning rod, and the outer wall of the convex plate 8 of the lower clamp 7 is provided with a positioning rod groove 12. The cooperation between the positioning rod and the positioning rod groove 12 can realize the quick alignment of the upper and lower clamps, avoid circumferential offset during installation, and improve assembly efficiency.

[0032] Connecting pipe 9: The connecting pipe 9 is a hollow tubular structure with sealing rings 10 fitted on the outer walls of both ends. It is the water flow channel between the water tank 4 and the toilet 1. Its two ends are inserted into the interior of the first connector 5 and the second connector 14 respectively, and are fixed by the clamping force of the clamping assembly to ensure the stable delivery of flushing water.

[0033] Sealing ring 10: Sealing ring 10 is installed on the outer wall of both ends of connecting pipe 9. It is made of elastic sealing material (such as rubber). When the clamp assembly is tightened, sealing ring 10 is squeezed and deformed. Its outer wall is tightly fitted with the inner wall of the first connector 5 and the second connector 14 to form a liquid seal and prevent flushing water leakage.

[0034] Protective component 11: Protective component 11 is fixed to the inner wall of the upper clamp 6 and the lower clamp 7. It is divided into two types: flat protective pad and array groove-type protective pad 16. The flat protective pad directly contacts the outer wall of the connecting pipe 9 to reduce the wear of the clamp on the pipe. The array groove-type protective pad 16 disperses the clamping force through the groove structure and contacts the outer wall of the first connector 5 and the second connector 14 at the same time to enhance the connection stability under complex working conditions.

[0035] Positioning rod groove 12 and bolt groove 13: Positioning rod groove 12 is opened on the outer wall of the protrusion plate 8 of the lower clamp 7 to provide sliding guidance for the positioning rod and ensure accurate positioning of the upper and lower clamps. Bolt groove 13 is opened on the outer wall of all protrusion plates 8 to allow the fixing bolt 15 to slide, which facilitates fine adjustment of the clamping position after positioning and ensures uniform distribution of clamping force.

[0036] Fixing bolt 15: The fixing bolt 15 is slidably installed in the bolt groove 13 of the upper clamp 6 and cooperates with the bolt groove 13 of the lower clamp 7 to fix the upper and lower clamps. By tightening the fixing bolt 15, the clamping force of the clamp assembly can be adjusted to balance the sealing effect and pipeline protection requirements.

[0037] 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.
