[0002] In the running process of EMU, air conditioning system will produce condensate water, if drainage is blocked, it will affect the normal operation of air conditioning system, and even possibly lead to water leakage etc. Traditional dredging method often relies on manual operation, and it is inefficient and has safety hazards. Therefore, it is particularly important to develop an efficient and safe condensate water drainage port dredging tool. UTILITY MODEL CONTENTS

[0003] In order to overcome the problems in the prior art, the utility model aims to provide a kind of EMU air conditioning condensate water drainage port dredging tool.

[0004] The utility model solves the technical scheme that the utility model employs to overcome its technical problems: a kind of EMU air conditioning condensate water drainage port dredging tool, comprising:

[0005] Straight pipe, telescopic sleeve pipe, elbow, valve, clamping seat;

[0006] The straight pipe and the elbow are connected by the telescopic sleeve pipe, and the valve is installed on the straight pipe;

[0007] The clamping seat includes first clamping block and second clamping block, and the first clamping block and the second clamping block are respectively arranged on the two sides of the elbow bending part.

[0008] Main working principle: straight pipe is used as the main conveying channel of condensate water, and its length and diameter are designed according to actual requirements to ensure that condensate water can flow smoothly. Elbow is used to change the flow direction of condensate water, so that it can adapt to the specific position of EMU air conditioning drainage port. Telescopic sleeve pipe serves as a bridge connecting straight pipe and elbow, and has adjustable mechanism inside, so that straight pipe and elbow can maintain certain flexibility and adjustability. When the length or angle of tool needs to be adjusted, telescopic sleeve pipe can be fine-tuned to adapt to different installation environments and drainage port positions.

[0009] Valve is installed on straight pipe to control the flow of condensate water. Before dredging operation starts, valve can be closed to prevent condensate water from flowing out; during dredging process, valve can be opened to allow condensate water to be discharged through tool. By opening and closing valve, the flow rate and direction of condensate water can be easily controlled, so as to realize accurate dredging of drainage port.

[0010] The clamping seat includes a first clamping block and a second clamping block, which are respectively arranged on both sides of the bending part of the elbow pipe. The design of the clamping seat is to ensure the stability of the elbow pipe during work, preventing it from loosening or falling off due to vibration or external force.

[0011] When the tool is installed in place, the first clamping block and the second clamping block will tightly clamp the two sides of the elbow pipe and be fixed on the equipment, forming a stable support structure. This design not only improves the overall stability of the tool, but also reduces the risk of poor dredging effect caused by the shaking of the elbow pipe.

[0012] During the dredging operation of the air-conditioning condensate water outlet of the EMU, the tool needs to be installed near the outlet first. By adjusting the length and angle of the telescopic sleeve, the straight pipe and the elbow pipe can be accurately connected to the outlet. Then, open the valve to allow the condensate water to be discharged through the tool. During the dredging process, the opening of the valve can be adjusted as needed to control the flow rate and direction of the condensate water. At the same time, the fixing effect of the clamping seat ensures the stability of the elbow pipe during work, preventing it from loosening or falling off due to vibration or external force. Finally, when the dredging operation is completed, close the valve and disassemble the tool for cleaning and maintenance.

[0013] In summary, the tool for dredging the air-conditioning condensate water outlet of the EMU realizes effective dredging and cleaning of the outlet through the cooperation of the straight pipe, telescopic sleeve, elbow pipe, valve and clamping seat. Its working principle is simple and clear, easy to operate, and has high practicality and reliability.

[0014] As a preferred, the straight pipe is arranged along the z-axis direction, the elbow pipe is bent towards the x-axis direction, and the first clamping block and the second clamping block are towards the y-axis direction.

[0015] As a preferred, it further includes an inner pipe, which is inserted from the end of the straight pipe and sequentially passes through the straight pipe, the telescopic sleeve and the elbow pipe, and extends from the end of the elbow pipe.

[0016] As a preferred, the telescopic sleeve, the end of the straight pipe and the end of the elbow pipe are all provided with threads, and the straight pipe and the elbow pipe are adjustably connected with the telescopic sleeve through the threads.

[0018] As a preferred, the clamping side openings of the first clamping block and the second clamping block are both circular arc openings.

[0019] Preferably, the first clamping block is provided with a first fixing hole at both ends of the fixed side, and the first fixing holes at both sides are connected by a screw rod.

[0020] Compared with the prior art, the utility model has the beneficial effects that:

[0021] The utility model discloses a combination of straight pipe, telescopic sleeve pipe, elbow pipe, valve and clamping seat, realizing compact structure and comprehensive function. This design not only makes the tooling easy to carry and store, but also can be flexibly applied in various complex environments, meeting the dredging needs of the EMU air conditioner condensate water drainage port. The design of telescopic sleeve pipe makes the tooling adapt to different drainage port positions and space limitations. By adjusting the length and angle of the telescopic sleeve pipe, it can be easily connected to drainage ports of various shapes and sizes, improving the versatility and practicality of the tooling. The design of the valve makes it easy to control the flow of condensate water. The operator only needs to switch the valve to conveniently control the discharge speed and direction of the condensate water, thereby realizing accurate dredging of the drainage port. The fixing effect of the clamping seat ensures the stability of the elbow pipe during work. Even under vibration or external force, the elbow pipe will not loosen or fall off, thereby ensuring the safety and reliability of the dredging operation. The connection between the various components of the tooling is tight and easy to disassemble, which makes cleaning and maintenance work simple and fast.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0029] Example 1

[0030] The present embodiment discloses a kind of EMUs air conditioning condensate water drainage port dredging tool, as shown in Fig. Figures 1-2 Straight pipe is used as the main conveying channel of condensate water, and its length and diameter are designed according to actual requirements to ensure that condensate water can flow smoothly. Elbow is used to change the flow direction of condensate water, so that it can adapt to the specific position of EMU air conditioning drainage port. Telescopic sleeve serves as a bridge connecting straight pipe and elbow, and has adjustable mechanism inside, so that straight pipe and elbow can maintain a certain flexibility and adjustability. When it is necessary to adjust the length or angle of the tool, fine adjustment can be made through telescopic sleeve to adapt to different installation environments and drainage port positions.

[0031] Valve is installed on straight pipe to control the flow of condensate water. Before dredging operation starts, valve can be closed to prevent condensate water from flowing out; during dredging process, valve can be opened to allow condensate water to be discharged through the tool. By opening and closing valve, the flow rate and direction of condensate water can be conveniently controlled, so as to realize accurate dredging of drainage port.

[0032] Clamping seat includes first clamping block and second clamping block, which are respectively arranged on both sides of elbow bend. The design of clamping seat is to ensure the stability of elbow during operation, so as to prevent it from loosening or falling off due to vibration or external force.

[0033] When the tool is installed in place, the first and second clamping blocks will tightly clamp the two sides of the elbow pipe and be fixed on the equipment, forming a stable support structure. This design not only improves the overall stability of the tool, but also reduces the risk of poor dredging effect caused by the shaking of the elbow pipe.

[0034] When performing the train air-conditioning condensate water drainage port dredging operation, the tool needs to be installed near the drainage port first. By adjusting the length and angle of the telescopic sleeve, the straight pipe and the elbow pipe can be accurately connected to the drainage port. Then, open the valve to allow the condensate water to be discharged through the tool. During the dredging process, the opening of the valve can be adjusted as needed to control the flow rate and direction of the condensate water. At the same time, the fixing effect of the clamping seat ensures the stability of the elbow pipe during the work process, preventing it from loosening or falling off due to vibration or external force. Finally, when the dredging operation is completed, close the valve and disassemble the tool for cleaning and maintenance.

[0035] In summary, the train air-conditioning condensate water drainage port dredging tool realizes effective dredging and cleaning of the train air-conditioning condensate water drainage port through the cooperation of the straight pipe, telescopic sleeve, elbow pipe, valve and clamping seat. Its working principle is simple and clear, easy to operate, and has high practicality and reliability.

[0036] In some optional embodiments, the straight pipe is arranged along the z-axis direction, the elbow pipe is bent towards the x-axis direction, and the first and second clamping blocks are oriented towards the y-axis direction. This arrangement makes the tool better adapt to the space layout inside the train, facilitating installation and use. The spatial positional relationship of the tool is clarified, improving the applicability and flexibility of the tool, facilitating installation and use inside the train.

[0037] In some optional embodiments, the inner pipe is inserted from the end of the straight pipe, sequentially passing through the straight pipe, telescopic sleeve and elbow pipe, and extending out from the end of the elbow pipe. The presence of the inner pipe can further enhance the dredging capacity of the tool, especially for small or stubborn blockages. When it is necessary to dredge small or stubborn blockages, the inner pipe can be used for more in-depth and delicate dredging operations. At the same time, the inner pipe can also serve as a flushing or blowing channel to improve the dredging efficiency.

[0038] In some optional embodiments, threads are arranged on the telescopic sleeve, the end of the straight pipe and the end of the elbow pipe. Through threaded connection, the straight pipe and the elbow pipe can be adjustably connected with the telescopic sleeve, that is, the relative position between the straight pipe and the elbow pipe can be adjusted as needed to adapt to the drain outlets at different positions. By rotating the straight pipe and the elbow pipe, the relative position between them and the telescopic sleeve can be adjusted, so that the length is adjustable. This adjustment method is simple and fast, and can meet the needs of drain outlet dredging at different positions. The length is adjustable through threaded connection, which improves the applicability and flexibility of the tool and facilitates dredging operation at drain outlets at different positions.

[0039] In some optional embodiments, the first clamping block and the second clamping block are designed as "H" shaped structures. The clamping side openings of the first clamping block and the second clamping block clamp the elbow pipe, forming a stable fixing structure. When the elbow pipe is inserted into the clamping seat, the clamping side openings of the first clamping block and the second clamping block tightly hold the elbow pipe, forming a stable fixing effect. This fixing method is simple and reliable, and can prevent the elbow pipe from loosening or falling off during work.

[0040] In some optional embodiments, the clamping side openings of the first clamping block and the second clamping block are designed as arc openings. This design makes the clamping side openings better adapt to the shape of the elbow pipe, improving the clamping effect. The arc opening can better fit the surface of the elbow pipe, forming a tighter fixing effect. This design makes the tool more stable and reliable during work. The design of the arc opening improves the clamping effect, making the tool more stable and reliable during work, prolonging the service life of the tool.

[0041] In some optional embodiments, first fixing holes are arranged at both ends of the fixed side of the first clamping block, and the first fixing holes on both sides are connected by a screw rod; second fixing holes are arranged at both ends of the fixed side of the second clamping block, and the second fixing holes on both sides are also connected by a screw rod. This design makes the clamping seat more firmly fixed on the EMU or other positions that need to be fixed. By connecting the fixed sides of the first clamping block and the second clamping block with screw rods, a stable fixing structure can be formed.

[0042] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical solution of the present application.
