Description

Technical Field

[0001] The utility model belongs to the technical field of ventilators, and particularly relates to a ventilator for locomotives. Background Technique

[0002] A ventilator is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine with an exhaust pressure lower than 1.5×10^4 Pa. Modern ventilators are widely used in the ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, the ventilation and induced draft of boilers and industrial furnaces, the cooling and ventilation in air conditioning equipment and household electrical appliances, the drying and selection of grains, the air supply of wind tunnels and the inflation and propulsion of hovercrafts, etc.

[0003] Ventilators are commonly used in railway electric locomotives to ventilate and dissipate heat inside the locomotive. However, during the use of existing ventilators, they may be impacted by the external environment, which may cause damage to the blades. When replacing the blades, a large number of screws need to be disassembled, wasting a lot of time.

[0004] Therefore, we provide a ventilator for locomotives to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a ventilator for locomotives. The motor drives the gear to rotate, which drives the toothed ring to rotate. The rotation of the toothed ring makes the connecting rod move under the guidance of the through hole, and drives the moving rod to move so that the fixing block can be clamped into or disengaged from the fixing slot, thereby indirectly completing the replacement of the blade, and solving the problem of inconvenient replacement in the prior art.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a ventilator for locomotives, including a fixing component, which includes a support frame, a fixed cylindrical plate arranged on the top of the support frame, a driving part arranged inside the fixed cylindrical plate, and a protective net arranged at the front end of the fixed cylindrical plate;

[0008] A replacement component, which includes a clamping component arranged inside the driving part, a driving component arranged inside the clamping component, and a fixing component arranged on one side of the driving component;

[0009] The clamping component includes a plurality of receiving sleeves evenly distributed inside the driving part, fixing slots opened inside the receiving sleeves, intrusion cylinders sleeved inside the receiving sleeves, blades arranged at the ends of the intrusion cylinders, and guiding sleeves evenly distributed inside the intrusion cylinders;

[0010] The driving component includes a fixing rod disposed inside the fixing card slot, a motor disposed at the end of the fixing rod, a driving gear disposed at the driving end of the motor, a toothed ring sleeved outside the driving gear, and a through hole penetrating the surface of the toothed ring;

[0011] The fixing component includes a connecting rod disposed inside the through hole, a moving rod disposed at the end of the connecting rod, and a fixing block disposed at the end of the moving rod.

[0012] The utility model is further arranged such that the intrusion cylinder is fixedly connected to the blade, and the intrusion cylinder is sleeved inside the receiving sleeve.

[0013] The utility model is further arranged such that the fixing rod is fixedly connected inside the intrusion cylinder, the driving end of the motor is fixedly connected to the driving gear, the driving gear is meshed with the toothed ring, the toothed ring is connected inside the intrusion cylinder through a rotating shaft, and the toothed ring is rotatably connected to the rotating shaft.

[0014] The utility model is further arranged such that the connecting rod is slidably connected to the through hole, the moving rod is slidably connected to the guiding sleeve, and the shape of the fixing block fits the shape of the fixing card slot.

[0015] The utility model is further arranged to further include an adjusting component, which includes a connecting component disposed at the center of the driving member and an adjusting component disposed inside the connecting component.

[0016] The utility model is further arranged such that the connecting component includes a fixing cylinder disposed at the center of the driving member, a power bevel gear disposed inside the fixing cylinder, a connecting bevel gear disposed outside the power bevel gear, and a connecting shaft disposed on the outward side of the connecting bevel gear.

[0017] The utility model is further arranged such that the adjusting component includes an extension shaft disposed on one side of the power bevel gear, a hexagonal prism disposed inside the extension shaft, a spring disposed between the extension shaft and the hexagonal prism, and an adapting handle disposed at the end of the spring.

[0018] The utility model is further arranged such that the power bevel gear is meshed with the connecting bevel gear, the power bevel gear is rotatably connected to the fixing cylinder, the extension shaft is fixedly connected to the end of the power bevel gear, a hole fitting the spring is formed inside the adapting handle, and the adapting handle is slidably connected to the extension shaft.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model drives the driving gear to rotate by starting the motor. The rotation of the driving gear drives the tooth ring to rotate. The surface of the tooth ring is penetrated by through holes. When the tooth ring rotates, the angles of the through holes change, so that the connecting rod inside the through holes moves. The connecting rod is connected to the moving rod. Therefore, when the connecting rod moves, it will drive the moving rod to move. The moving rod is fixedly connected to the fixed block. So the fixed block and the moving rod move simultaneously. When the fixed block is stuck into the fixed card slot, the fixation of the blade is completed. When the fixed block disengages from the fixed card slot, the disassembly of the blade is completed. The whole process completes the disassembly of the blade without the need to disassemble a large number of bolts, which is convenient for replacing the blade and saves time.

[0021] 2. The utility model presses down the adapter handle to sleev it on the hexagonal prism. The two fit together, making the extension shaft and the adapter handle spliced into a whole. When the adapter handle is rotated, the extension shaft can also rotate synchronously. The extension shaft is fixedly connected to the driving bevel gear. According to the principle of gear meshing connection, the driving bevel gear drives the connecting bevel gear to rotate. One end of the connecting bevel gear is fixedly connected to the blade through a connecting shaft. Thus, the purpose of adjusting the blade angle is achieved by the rotation of the connecting bevel gear, changing the air flow direction and improving the ventilation efficiency.

[0022] Of course, it is not necessary for any product implementing the utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS
