Technical Field
[0001] This utility model relates to a manually operated top louver structure for railway power generation cars, belonging to the technical field of equipment for intercity trains. Background Technology
[0002] With the rapid development of my country's economy, the railway industry has also developed rapidly, with increasingly higher requirements for the functionality, convenience, and practicality of railway products. Railway passenger car generator cars are generally used to supply power to electrical equipment (including lighting, air conditioning, or refrigeration units) in other carriages. The generator car is equipped with a generator set for generating electricity. Maintaining the normal operation of the generator set requires a cooling system. Hot air is exhausted outside the car through louvers on the roof to ensure the normal operation of the diesel generator set. The roof louvers are installed on the car body cover, with the lower part directly connected to the generator room and the generator set via air ducts. The roof louvers must meet both ventilation and rain protection requirements. Currently, there are two main types of roof louvers operating on railways: the first is a fixed-blade roof louver, and the second is an automatically opening and closing blade roof louver. The first type, the fixed-blade roof louver, is characterized by fixed blades, providing some rain protection. The generator set is not directly below the roof louver; air is delivered through air ducts, and the airflow is significantly reduced when it reaches the roof louver from the generator. The second type of automatically opening and closing blade top louver features automatic blade opening and closing, with rain protection when closed. The generator set is directly below the top louver, and the wind power from the generator directly opens the movable blades. When the generator stops working, the blades close directly due to gravity. When the generator set is not directly below the top louver, a duct is needed to connect the generator set and the top louver. Top louvers with fixed blades cannot meet the ventilation requirements. While top louvers with automatically opening and closing blades can normally meet the ventilation requirements, insufficient wind power often results in the blades failing to open automatically. Adding a manual switch to the automatically opening and closing blade top louver design allows for manual control of the blades' opening and closing when the top louver fails to open automatically. However, how to install a manual switch inside the generator car without interfering with the generator set's operation is a pressing technical problem that needs to be solved. Utility Model Content
[0003] The purpose of this invention is to adopt a manually opening and closing top louver structure for railway generator cars. A manual switch is installed in the air duct between the top louver and the generator set. When the top louver cannot open automatically, the opening and closing of the blades can be manually controlled to avoid interference with the operation of the generator set, thus solving the above-mentioned technical problems existing in the prior art.
[0004] The technical solution of this utility model is:
[0005] A manually operated top louver structure for a railway power generation car is disclosed. The top louver is installed on the window of the roof of the power generation car and is connected to the generator set via a duct. The generator set is not directly below the top louver. The top louver includes multiple movable blades arranged in a row. The movable blades are connected to a manual switch that controls their opening and closing. The manual switch is located in the duct below the movable blades. The manual switch includes a crank arm, a connecting piece, a connecting rod, a handle rod, and a ring. One end of the connecting piece is fixed to the movable blade, and the other end of the connecting piece is hinged to the connecting rod below the movable blade. The end of the connecting rod is connected to the top of the handle rod via the crank arm. The handle rod extends downward along the duct and has a ring at its bottom. A hook matching the ring is provided on the inner wall of the duct corresponding to the ring. An inspection door is provided on the duct wall corresponding to the ring and the hook. If the top louvers cannot open automatically, open the inspection door on the duct wall, reach into the duct, and push the handle upward. The crank arm and connecting rod, which are fixed together with the handle, will move upward together. The connecting piece on the connecting rod will apply an upward force to the movable blades, pushing them to open. After manually opening the top louvers, hang the ring at the bottom of the handle on the hook on the inner wall of the duct to avoid accidental operation, and then close the inspection door.
[0006] The multiple movable blades are arranged along the length of the connecting rod. All the movable blades in this row are connected to a connecting rod through their respective connecting pieces. Moving the connecting rod upwards can open all the movable blades in this row.
[0007] The movable blades are arranged in multiple rows, and a connecting rod is provided below each row of movable blades. All movable blades in each row are connected to the corresponding connecting rod in that row through their respective connecting plates. The multiple connecting rods are parallel to each other, and the ends of all the connecting rods are fixedly connected to the same connecting round rod through a crank arm. The connecting round rod is fixedly connected to the top of the handle rod.
[0008] The movable blade is hinged to the manual switch linkage by bolts.
[0009] The inner wall of the air duct is provided with a switch positioning seat, and the switch positioning seat is provided with a hook.
[0010] The top louver is composed of a left louver and a right louver. The left louver and the right louver are each matched with their own manual switches, namely the left manual switch and the right manual switch. Hooks matching the left manual switch and the right manual switch are respectively provided on the left and right walls inside the air duct. The manual opening of the left louver and the right louver is controlled by the left manual switch and the right manual switch respectively.
[0011] The beneficial effects of this utility model are as follows: A manual switch is installed in the air duct between the top louver and the generator set. When the top louver cannot open automatically, the opening and closing of the blades can be manually controlled, avoiding interference with the operation of the generator set. This achieves both the ventilation volume and the functionality of the top louver. Attached Figure Description
