Description

Technical Field

[0001] This utility model relates to the field of rail transit locomotive technology, and in particular to a locomotive ventilation and cooling system and a locomotive. Background Technology

[0002] Currently, rail transit locomotive equipment rooms generally employ a structure where independent ventilation fans ventilate the equipment room, or a structure where traction fans (or cooling tower fans) bypass a portion of the cooling air to ventilate the equipment room. The traction fan bypass structure not only reduces the amount of locomotive equipment required, saving space and lowering costs, but also improves the utilization rate of the locomotive equipment.

[0003] Since the locomotive equipment room primarily houses electrical equipment, its ventilation system must effectively filter dust and water to ensure the cleanliness of the air entering the room. Cooling tower ventilation, on the other hand, mainly ventilates and cools the coolers, which do not require rainwater filtration and have relatively lower dust filtration requirements. In related technologies, the filtration devices in the ventilation and cooling systems are typically installed in the main ventilation circuit. This means the filtration devices filter the airflow throughout the entire system, increasing air resistance as the filtered air passes through the coolers, reducing ventilation volume, and ultimately affecting the system's cooling efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a locomotive ventilation and cooling system and a locomotive, so as to solve the problem that the ventilation and cooling system in the prior art has poor cooling effect due to the increased air resistance flowing through the cooler.

[0005] On one hand, this utility model provides a locomotive ventilation and cooling system, including a fan, a cooler, and a main air duct. The fan is installed at the air inlet of the locomotive, and the main air duct connects the fan and the cooler. The locomotive ventilation and cooling system further includes: a bypass air duct that connects the main air duct and a bypass port between the locomotive's equipment compartment; a waterproof filter installed at the bypass port and located inside the bypass air duct, which filters rainwater entering the locomotive's equipment compartment; and a dust filter installed at the bypass port and located outside the bypass air duct, which filters dust entering the locomotive's equipment compartment.

[0006] As an optional technical solution for the locomotive ventilation and cooling system, the dust filter includes a dust mounting frame and a dust filter element. The dust mounting frame is installed at the bypass port and located outside the bypass ventilation duct. The dust mounting frame has a mounting cavity communicating with the bypass ventilation duct. The dust filter element is disposed in the mounting cavity and can filter dust entering the equipment compartment of the locomotive.

[0007] As an optional technical solution for the locomotive ventilation and cooling system, the dust filter element is a palm fiber filter cotton or an elastic fiber filter cotton.

[0008] As an optional technical solution for the locomotive ventilation and cooling system, the dust mounting frame includes a frame body and a sealing door. The frame body is installed at the bypass opening and located outside the bypass ventilation duct. One end of the sealing door is pivotally connected to the frame body, and the other end is detachably mounted on the frame body. The sealing door has a guide hole that connects the mounting cavity to the equipment room of the locomotive. The frame body has the mounting cavity.

[0009] As an optional technical solution for the locomotive ventilation and cooling system, the dust mounting frame also includes a wing bolt, which passes through the other end of the sealing door and is threadedly connected to the frame body.

[0010] As an optional technical solution for the locomotive ventilation and cooling system, the blocking door has a flow guide grille, which is installed at the flow guide hole to guide the air blowing towards the equipment room of the locomotive.

[0011] As an optional technical solution for the locomotive ventilation and cooling system, there are multiple guide holes and multiple guide grilles, and the multiple guide holes and multiple guide grilles are arranged in a one-to-one correspondence.

[0012] As an optional technical solution for the locomotive ventilation and cooling system, the waterproof filter is a corrugated filter or an inertial filter.

[0013] As an optional technical solution for the locomotive ventilation and cooling system, the locomotive ventilation and cooling system also includes a metal filter screen, which is installed at the air inlet.

[0014] On the other hand, this utility model provides a locomotive, including a locomotive body and a locomotive ventilation and cooling system according to any of the above-mentioned solutions, wherein the locomotive ventilation and cooling system is installed on the locomotive body.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention provides a locomotive ventilation and cooling system, comprising a bypass ventilation duct, a waterproof filter, and a dust filter. The bypass ventilation duct connects the main air duct to the locomotive's equipment compartment. The waterproof filter is installed at the bypass opening within the duct, while the dust filter is installed at the bypass opening outside the duct. This allows the waterproof filter to filter rainwater entering the locomotive's equipment compartment, and the dust filter to filter dust, ensuring the cleanliness of the cooling air entering the equipment compartment. Furthermore, by eliminating the need for a waterproof and dust filter in the main air duct, the system maintains sufficient airflow to the cooler, reduces air resistance, and improves cooling efficiency. Additionally, since the cooler does not require waterproofing and only needs protection against a small amount of larger dust particles, the system meets the ventilation, dust filtration, and water filtration requirements of the entire locomotive's equipment compartment without altering the overall ventilation and cooling system's functionality. This reduces the overall equipment layout, lowers auxiliary power consumption, and lowers the overall cost of the locomotive. The locomotive ventilation and cooling system of this invention effectively solves the problem of poor cooling effect caused by increased air resistance flowing through the cooler in the existing ventilation and cooling system.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figures 1 to 2As shown, this embodiment provides a locomotive ventilation and cooling system, including a fan 4, a cooler 5, and a main air duct 6. The fan 4 is installed at the locomotive's air inlet, and the main air duct 6 connects the fan 4 and the cooler 5. The locomotive ventilation and cooling system also includes a bypass air duct 1, a waterproof filter 2, and a dust filter 3. The bypass air duct 1 connects the main air duct 6 to a bypass opening in the locomotive's equipment compartment; the waterproof filter 2 is installed at the bypass opening and located inside the bypass air duct 1, and can filter rainwater entering the locomotive's equipment compartment; the dust filter 3 is installed at the bypass opening and located outside the bypass air duct 1, and can filter dust entering the locomotive's equipment compartment.

[0032] The locomotive ventilation and cooling system of this invention connects the main air duct 6 and the locomotive's equipment compartment via a bypass duct 1. A waterproof filter 2 is installed at the bypass opening, inside the bypass duct 1, while a dust filter 3 is installed at the bypass opening, outside the bypass duct 1. This allows the waterproof filter 2 to filter rainwater entering the locomotive's equipment compartment, and the dust filter 3 to filter dust, ensuring the cleanliness of the cooling air entering the equipment compartment. Furthermore, since the waterproof filter 2 and dust filter 3 are not installed in the main air duct, the ventilation volume of the cooler 5 is guaranteed, reducing air resistance and improving cooling efficiency. Moreover, since the cooler 5 does not require waterproofing and only needs protection against a small amount of larger particles, the system meets the ventilation, dust filtration, and water filtration requirements of the entire vehicle's equipment compartment without altering the overall ventilation and cooling system's functionality. This reduces the overall equipment layout, lowers auxiliary power consumption, and lowers the overall vehicle cost. The locomotive ventilation and cooling system of this utility model effectively solves the problem of poor cooling effect caused by increased air resistance flowing through the cooler 5 in the existing ventilation and cooling system.

[0033] It should be noted that the waterproof filter 2 is installed in the bypass ventilation duct 1 because the waterproof filter 2 does not require maintenance.

[0034] In some embodiments, the dust filter 3 includes a dust mounting frame 31 and a dust filter element 32. The dust mounting frame 31 is installed at the bypass opening and located outside the bypass ventilation duct 1. The dust mounting frame 31 has a mounting cavity communicating with the bypass ventilation duct 1, and the dust filter element 32 is disposed within the mounting cavity. The dust filter element 32 can filter dust entering the locomotive's equipment compartment. Positioning the dust filter 3 outside the bypass ventilation duct 1 facilitates the replacement of the dust filter element 32, making it convenient and quick.

[0035] In this embodiment, the dust filter element 32 includes, but is not limited to, palm fiber filter cotton or elastic fiber filter cotton. Among them, palm fiber filter cotton has the advantages of good environmental protection, good filtration effect and strong durability; elastic fiber filter cotton has the advantages of good filtration effect, strong adhesion and strong durability.

[0036] In some embodiments, the dust mounting frame 31 includes a frame body 311 and a sealing door 312. The frame body 311 is installed at the bypass opening and located outside the bypass ventilation duct 1. One end of the sealing door 312 is pivotally connected to the frame body 311, and the other end is detachably mounted on the frame body 311, facilitating the opening and closing of the sealing door 312. The sealing door 312 also has a guide hole, through which the mounting cavity can be connected to the locomotive's equipment compartment, allowing filtered air to enter the locomotive's equipment compartment. The frame body 311 contains the mounting cavity.

[0037] Optionally, one end of the blocking door 312 and the frame 311 are connected by a hinge.

[0038] Furthermore, the dust mounting frame 31 also includes a wing bolt 313, which passes through the other end of the sealing door 312 and is threadedly connected to the frame body 311. This configuration allows for quick replacement of the dust filter element 32 by removing the wing bolt 313, enabling rapid installation and removal of the dust filter element 32 that requires maintenance, thereby improving the maintainability of the entire vehicle.

[0039] In some embodiments, the blocking door 312 has a flow guide grille 3121, which is installed at the flow guide hole. The flow guide grille 3121 can guide the air blowing towards the equipment compartment of the locomotive, reduce the impact of air on the driver and passengers, and improve the comfort of the driver and passengers.

[0040] In this embodiment, there are multiple airflow guide holes and multiple airflow guide grilles 3121, and the multiple airflow guide holes and multiple airflow guide grilles 3121 are arranged in a one-to-one correspondence. This arrangement can increase the airflow between the equipment compartments entering the locomotive.

[0041] In some embodiments, the waterproof filter 2 includes, but is not limited to, a corrugated filter or an inertial filter. The corrugated filter has high filtration accuracy and durability; the inertial filter has high filtration accuracy, self-cleaning ability, and wide applicability.

[0042] Furthermore, the locomotive ventilation and cooling system also includes a metal filter 7, which is installed at the air inlet. This arrangement ensures that larger contaminants are intercepted by the metal filter 7, while smaller contaminants, after passing through the metal filter 7, can be directly blown out of the cooler through the gaps in the cooler's air fins, preventing contaminants from clogging the cooler.

[0043] This embodiment also provides a locomotive, including a locomotive body and the locomotive ventilation and cooling system described above, the locomotive ventilation and cooling system being installed on the locomotive body. The locomotive using this invention, due to the bypass ventilation duct 1 connecting the main air duct 6 and the locomotive's equipment compartment, and the installation of a waterproof filter 2 inside the bypass ventilation duct 1 at the bypass opening, and a dust filter 3 outside the bypass ventilation duct 1 at the bypass opening, allows the waterproof filter 2 to filter rainwater entering the locomotive's equipment compartment, and the dust filter 3 to filter dust entering the equipment compartment, thus ensuring the cleanliness of the cooling air entering the locomotive's equipment compartment. Furthermore, since the locomotive ventilation and cooling system of this invention does not include a waterproof filter 2 and a dust filter 3 in the main air duct, it ensures sufficient ventilation for the cooler 5, reduces the increase in air resistance flowing through the cooler 5, and improves the cooling effect. Furthermore, since the cooler 5 does not require waterproofing and only needs to prevent dust from a small amount of larger particles, it is possible to meet the ventilation, dust filtration, and water filtration needs between vehicle equipment without changing the function of the overall vehicle ventilation and cooling system. This results in a reduction in the layout of vehicle equipment, a decrease in auxiliary power consumption, and a reduction in overall vehicle cost. The locomotive utilizing this invention effectively solves the problem of poor cooling performance in existing ventilation and cooling systems due to increased air resistance flowing through the cooler 5.

[0044] The advantages of this utility model are as follows:

[0045] 1. Without changing the cooling capacity of the locomotive ventilation and cooling system (converter cooling or transformer cooling), waterproof filters and dust filters are installed on the ventilation devices of the bypass equipment room, which fully and reasonably meets the needs of different filtration precision between the various systems.

[0046] 2. Waterproof filters and dust filters in the locomotive equipment room. Waterproof filters require no maintenance, and the dust filter element in the dust filter adopts a quick-install structure, which is easy to disassemble and replace, and has high maintainability.

[0047] 3. The installation of air deflectors can guide the cooling air blowing towards the equipment compartments of the locomotive, reducing the impact of air on the driver and passengers and improving their comfort.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
