Abstract
Description
Technical Field
[0001] This invention relates to the field of dual-source locomotive technology, and more particularly to a waterproof installation structure for a cooling device of a dual-source locomotive. Background Technology
[0002] Dual-source locomotives with integrated internal electric power are locomotives capable of using two or more energy sources (such as electricity and diesel) simultaneously. For example, the Fuxing high-speed locomotive with integrated internal electric power is equipped with a diesel engine. Locomotives powered by diesel engines require cooling devices to cool the diesel engine system. The locomotive's engine room contains numerous pieces of equipment. To effectively utilize the limited space, corridors and engine room equipment are arranged below the cooling devices and their associated air intake ducts. The cooling devices are typically installed on suspended beams on the side walls of the engine room. Since the cooling devices, like the locomotive roof, are exposed, gaps exist between the cooling devices and the side walls after installation. How to achieve the installation of the cooling devices without increasing the structure or weight, while ensuring that rainwater does not enter the engine room through these gaps, was a problem that had to be solved during the research and development process.
[0003] Therefore, there is a need in the existing technology to improve the waterproof installation structure of the cooling device for dual-source locomotives. Summary of the Invention
[0004] In view of this, the purpose of this invention is to propose a waterproof installation structure for the cooling device of a dual-source locomotive. While making full use of the limited installation space in the machine room, the installation structure of the cooling device is optimized. In combination with the installation structure of the cooling device, a sealing structure and a drainage system are designed to make it waterproof, and welding deformation is reduced, thereby improving the disassembly and assembly efficiency of the cooling device.
[0005] To achieve the above objectives, embodiments of the present invention provide a waterproof mounting structure for a cooling device on a dual-source locomotive. The cooling device is disposed on the top of the locomotive, and the waterproof mounting structure includes:
[0006] The mounting base extends across the locomotive's power compartment, partition wall, and cooling compartment. The mounting base includes a first mounting plate, a second mounting plate, and a third mounting plate that are arranged in parallel and perpendicularly connected to the first and second mounting plates. The first and second mounting plates are perpendicularly connected to the vertical inner wall of the cantilever beam on the locomotive's side wall. The first mounting plate is provided with multiple detachable connecting seats. The first and second mounting plates are symmetrically provided with a first opening and a second opening, which are connected to the air duct of the locomotive's cooling compartment.
[0007] Two blocking plates are respectively set at both ends of the mounting base to form a fully enclosed structure of the mounting base;
[0008] Multiple seals are provided at the connection between the mounting base and the upper suspension beam and cooling device.
[0009] In some implementations, the structure further includes:
[0010] The eaves include a first extension and a second extension. The first extension is fixed to the upper suspension beam, and the second extension is connected to the first extension at an obtuse angle.
[0011] In some embodiments, the plurality of seals includes a first seal and a second seal, the first seal being disposed at the connection between the first mounting plate and the upper suspension beam, and the second seal being disposed at the contact position between the third mounting plate and the cooling device.
[0012] In some embodiments, a third seal is also provided between the second seal and the second extension.
[0013] In some implementations, the seal is a rubber seal.
[0014] In some embodiments, there are five detachable connectors, which are evenly spaced on the first mounting plate.
[0015] In some embodiments, the detachable connector is a live screw seat, and the cooling device is fixedly connected to the live screw seat by fasteners.
[0016] In some implementations, the mounting base is welded to the upper suspension beam.
[0017] In some implementations, the first opening and the second opening have the same diameter.
[0018] In some embodiments, the second mounting plate and the third mounting plate are integrally formed L-shaped mounting plates, and the first mounting plate is welded to the third mounting plate so as to be arranged parallel to the second mounting plate.
[0019] The present invention has at least the following beneficial technical effects:
[0020] The device of this invention provides a waterproof installation structure for a cooling device, updating the original mounting structure of the locomotive cooling device on the suspension beam on the side wall of the car body. The new mounting structure takes into account both the installation and waterproof sealing functions of the cooling device, avoiding welding deformation caused by thin plate welding. This structure is currently used for the installation of cooling devices in internal electric dual-source diesel locomotives. After application, the cooling device is sealed with two seals, preventing leakage at the joint between the locomotive cooling device and the car body steel structure. The connection and drainage functions of the cooling device mounting base enable this structure to not only have the function of sealing and waterproofing, but also the function of drainage. The two functions are realized simultaneously, which greatly improves the sealing effect and avoids the need for sealant, improving the efficiency of disassembling and assembling the cooling device.

For example, when an element is referred to as "connected to" another element, it can be directly or indirectly connected to that other element.

[0036] like Figure 1 The diagram shows a schematic of the cooling system and air duct of a conventional dual-power locomotive. The engine compartment air duct consists of a cooling compartment air duct 90, a power compartment air duct 80, and a partial partition wall. Due to the special characteristics of the power compartment, the power compartment air intake duct cannot be perpendicularly connected to the cooling system 60. The power compartment air duct 80 can only connect to the partition wall before connecting to the cooling system 60. A gap exists between the cooling system 60 and the power compartment air intake duct, preventing rainwater from entering the locomotive through the cooling system installation gaps. This prevents water from entering the power compartment and being discharged outside the locomotive. Therefore, a drainage and sealing structure must be designed to prevent water from entering the power compartment.
[0037] In the existing technical solution, the cooling device 60 is installed on the locomotive side wall via a mounting bracket pre-welded to the upper surface of the side wall suspension beam 50. The cooling device 60 spans the side walls on both sides of the locomotive. Rainwater from outside enters the locomotive through the gap between the cooling device 60 and the roof, flows over the upper surface of the upper suspension beam 50 and the upper surface of the cooling partition plate, and then flows down the vertical surface of the cooling partition plate into the cooling compartment before being discharged outside the locomotive. If only the transverse surfaces at both ends of the cooling device are sealed with sealant according to the site conditions, this method makes disassembly and reassembly of the cooling device difficult. Furthermore, re-sealing is required when reinstalling the cooling device after disassembly, resulting in low disassembly and reassembly efficiency.
[0038] Therefore, the present invention provides a waterproof mounting structure for the cooling device of a dual-source locomotive, such as... Figures 2-5 The diagram shown is a schematic representation of an embodiment of this structure. The cooling device 60 is mounted on the top of the locomotive and installed on the locomotive side wall via a mounting base 10 pre-welded to the upper surface of the upper suspension beam 50. A waterproof mounting structure is positioned between the two upper suspension beams 50 to fix and support the cooling device 60. A front view of the waterproof mounting structure is shown below. Figure 2 As shown, it specifically includes:
[0039] Mounting bracket 10, which extends across the locomotive's power compartment, partition wall, and cooling compartment, such as... Figure 4 As shown, the mounting base 10 includes a first mounting plate 11, a second mounting plate 12 arranged in parallel, and a third mounting plate 13 perpendicularly connected to the first mounting plate 11 and the second mounting plate 12. The first mounting plate 11 and the second mounting plate 12 are perpendicularly connected to the vertical inner wall of the cantilever beam 50 on the side wall of the locomotive. The first mounting plate 11 is provided with a plurality of detachable connecting seats 14. The first mounting plate 11 and the second mounting plate 12 are symmetrically provided with a first opening 15 and a second opening 16. The first opening 15 and the second opening 16 are connected to the air duct 90 of the locomotive cooling room.
[0040] Two blocking plates 20 are respectively disposed at both ends of the mounting base 10 to make the mounting base form a fully enclosed structure;
[0041] Multiple seals are provided at the connection between the mounting base 10 and the upper suspension beam 50 and the cooling device 60.
[0042] Furthermore, the plane of the first mounting plate 11 should be lower than the top position of the upper suspension beam 50, so that the overall center of gravity of the mounting base 10 is lower than the top plane of the upper suspension beam 50, forming a stepped structure.
[0043] Furthermore, the waterproof installation structure also includes a rain eave 40, see reference. Figure 5The eaves 40 includes a first extension 41 and a second extension 42. The first extension 41 is fixed to the upper suspension beam 50, and the second extension 42 is connected to the first extension 41 at an obtuse angle. The eaves 40 is disposed at the top of the upper suspension beam 50 to block rainwater flowing in along the direction of the arrow. In some embodiments, the upper part of the blocking plate 20 is fully welded to the eaves 40, and the lower part of the blocking plate 20 is fully welded to both ends of the cooling device mounting base 10 and the suspension beam 50 on the side wall to form a closed cavity.
[0044] Furthermore, the plurality of seals includes a first seal 30 and a second seal 31. The first seal 30 is disposed at the connection between the first mounting plate 11 and the upper suspension beam 50, and the second seal 31 is disposed at the contact position between the third mounting plate 13 and the cooling device 60. In some embodiments, because the upper suspension beam 50 has a chamfered treatment, the first mounting plate 11 and the upper suspension beam 50 cannot be kept on the same horizontal plane, that is, there is a gap between the first mounting plate 11, the upper suspension beam 50, and the cooling device 60, which easily allows rainwater to leak in. Therefore, the first seal 30 is provided to seal this gap. Preferably, the first seal 30 is a sealing strip, such as... Figure 3 As shown, the sealing strip is long and narrow, positioned at the connection between the mounting base 10 and the upper suspension beam 50. The second sealing element 31 is an inverted U-shaped sealing strip, as shown... Figure 4 As shown, the second seal 31 is inverted and placed on the third mounting plate 13 to seal the gap between the third mounting plate 13 and the cooling device 60. To prevent water from overflowing into the vehicle when heavy rain occurs, the second seal 31 acts as a secondary seal, filling the gap b between the cooling device mounting plate 10 and the cooling device 60, thus trapping rainwater inside the mounting plate and preventing it from seeping into the locomotive interior. Preferably, a third seal 33 is also provided between the second seal 31 and the second extension 42, such as... Figure 5 As shown, the second seal 31 and the third seal 33 on the rain rim 4 are integrated into one unit to prevent water from entering the non-air duct area inside the vehicle from both ends of the cooling device, thus achieving a third layer of waterproofing.
[0045] The first opening 15 and the second opening 16 within the mounting bracket 10 are both drainage outlets. Since the power compartment cannot drain water via the power compartment air duct, the drainage outlets of the cooling device mounting bracket 10 are only located in the cooling compartment; the power compartment has no lower-level drainage outlet. Water entering the vehicle from the power compartment through gap a passes through the cooling device mounting bracket, is drained into the cooling compartment air duct 90 through the lower-level drainage outlet of the cooling compartment, and is then discharged outside the vehicle through the side wall air duct 70. This achieves the goal of guiding water entering the power compartment into the cooling compartment and discharging it outside the vehicle, eliminating the risk of water entering the power compartment.
[0046] Furthermore, there are five detachable connectors 14, which are evenly spaced on the first mounting plate 11. In some embodiments, the detachable connectors 14 are live screw seats, and the cooling device 60 is fixedly connected to the live screw seat by mounting fasteners 17.
[0047] Furthermore, the mounting base 10 is welded to the upper suspension beam 50.
[0048] Furthermore, the first opening 15 and the second opening 16 have the same diameter.
[0049] Furthermore, the second mounting plate 12 and the third mounting plate 13 are integrally formed L-shaped mounting plates, and the first mounting plate 11 is welded to the third mounting plate 13 so as to be arranged parallel to the second mounting plate 12.
[0050] The device of this invention is assembled around a cooling device mounting base to form a closed groove with both receiving and drainage functions. A first seal fills the mounting gap a, forming the first layer of waterproofing. When the first layer fails, rainwater flows down the steps formed by the height difference between the side wall beam and the cooling device mounting base, then flows into the cooling room air duct through two drainage openings on the mounting plate, and finally exits the vehicle through the side wall air inlet, achieving a second layer of waterproofing. To prevent water from overflowing into the vehicle when the cooling device mounting base is full during heavy rainfall, a second seal is provided, filling the gap b between the cooling device mounting base and the cooling device. This second seal, along with the third seal on the rain eaves 4, forms a single unit, preventing water from entering the non-air duct area of the vehicle from both ends of the cooling device, achieving a third layer of waterproofing. This invention not only has the function of sealing and waterproofing but also the function of drainage, achieving both functions simultaneously, significantly improving the sealing effect and avoiding the need for sealant, thus improving the efficiency of assembling and disassembling the cooling device.
