Description

Technical Field

[0001] This utility model relates to the field of hydropower equipment technology, specifically to a disassembly and assembly device for a cooling fan motor. Background Technology

[0002] A bulb turbine generator is a common structure in hydropower. A bulb turbine generator typically includes the main unit, a bulb housing within a flow channel, and a cooling fan for outputting cooling air. The main unit includes a stator frame, a stator mounted on the stator frame and consisting of a stator core and stator bars, a rotor support, and a rotor rotatably mounted on the rotor support and consisting of a rotor yoke and rotor poles.

[0003] Because the bulb-type axial-flow turbine generator is installed in a closed bulb body within the flow channel, the heat generated by the stator and rotor during power generation is not easily dissipated, resulting in poor cooling conditions for the entire unit and hindering heat dissipation and cooling of the generator. To address the problems existing in the prior art, CN220087086U discloses a novel bulb-type axial-flow generator without a cooler (hereinafter referred to as Prior Art 1), which includes a stator, a rotor inside the stator, a bulb head on the left side of the stator, a fan inside the bulb head, a combined bearing on the middle side of the stator, flow channel covers rotating on both the left and right ends of the bottom side of the stator, an air inlet fixedly connected to the right end of the bottom side of the stator, a self-cooling cavity on the outer wall of the stator, and an exhaust vent on the top side of the bulb head.

[0004] In the existing technology 1, the unit is cooled by setting up a fan and a self-cooling chamber. However, when disassembling and assembling the fan motor used for ventilation and cooling in the current cross-flow unit, it is necessary to use a hand hoist and manual support to disassemble it, and there are no corresponding special disassembly and assembly tools. The disassembly and installation of the cooling fan motor takes a long time and is inconvenient for inspection and maintenance. Utility Model Content

[0005] The purpose of this utility model is to provide a disassembly and assembly device for a cooling fan motor. In actual use, it can solve the problems in the prior art where the disassembly and assembly of the fan motor in the cross-flow unit requires the use of a hand hoist and manual support, without corresponding special disassembly and assembly tools; the disassembly and installation of the cooling fan motor takes a long time and is inconvenient for inspection and maintenance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A disassembly and assembly device for a cooling fan motor includes a base plate and a connecting assembly, wherein the connecting assembly is mounted on the base plate;

[0008] The top of the connecting component is provided with an arc-shaped structure, on which support plates are symmetrically installed. An adjustment component is installed on the support plate, which is used to adjust the position of the fan motor; the base plate is an arc-shaped structure.

[0009] The base plate is provided with several mounting slots, and movable wheels are rotatably connected in the mounting slots.

[0010] Preferably, the connecting component includes two connecting frames, the top of which is provided with the arc-shaped structure, and the tops of the two connecting frames are connected by the support plate.

[0011] Preferably, the adjustment assembly includes adjusting bolts symmetrically arranged on the front and rear sides of the support plate, and the adjusting bolts are threadedly connected to the support plate.

[0012] Preferably, a rotating block is rotatably mounted on the end of the adjusting bolt that contacts the fan motor.

[0013] Preferably, the base plate is provided with a slot.

[0014] Preferably, the support plate has ball bearings installed on the side that contacts the fan motor.

[0015] Preferably, a limiting frame is fixedly connected to the base plate, and the limiting frame is threaded with limiting bolts for fixing the moving wheels.

[0016] Preferably, a throttle handle is mounted on the adjusting bolt.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this utility model, when the fan motor needs to be disassembled, the connecting components and adjusting components need to be moved to the corresponding position of the fan motor by the moving wheels installed on the base plate. Since the inner wall of the cooling fan duct is an arc surface, by setting an arc-shaped base plate with the same or similar curvature as the arc surface, it can fit tightly against the inner wall of the fan duct during movement, reducing gaps during movement, avoiding jamming or vibration caused by structural mismatch, and improving the smoothness of movement.

[0019] The adjustment component can limit the motor's position and adjust its location during the installation and removal of the motor, facilitating quick and accurate installation and removal. The arc-shaped structure at the top of the connecting component can fit more closely with the structure of the fan motor mounting position and avoid interference between the connecting component and the fixed parts around the fan motor during the installation and removal of the fan motor.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] See Figures 1-3 This embodiment discloses a disassembly and assembly device for disassembling and assembling the motor of a cooling fan. Specifically, it is a disassembly and assembly device for a cooling fan motor, including a base plate 101 and a connecting component 102, wherein the connecting component 102 is mounted on the base plate 101.

[0034] The top of the connecting component 102 is provided with an arc-shaped structure, and a support plate 103 is symmetrically installed on the arc-shaped structure. An adjustment component 104 is installed on the support plate 103, and the adjustment component 104 is used to adjust the position of the fan motor; the base plate 101 has an arc-shaped structure.

[0035] The base plate 101 is provided with a plurality of mounting grooves 105, and movable wheels 113 are rotatably connected in the mounting grooves 105.

[0036] In this invention, since the fan motor for ventilation and cooling is installed inside the bulb, when the fan motor needs to be disassembled, the connecting assembly 102 and the adjusting assembly 104 need to be moved to the corresponding position of the fan motor using the moving wheels 113 mounted on the base plate 101. Because the inner wall of the cooling fan duct is an arc surface, the base plate 101, with an arc structure whose curvature is consistent with or similar to the arc surface, can closely fit the inner wall of the fan duct during movement, reducing gaps during movement, avoiding jamming or vibration caused by structural mismatch, and improving the smoothness of movement. The adjusting assembly 104 is used for disassembling and assembling the motor. During the process, the motor position can be adjusted while limiting the motor, which facilitates quick and accurate installation and disassembly; the arc-shaped structure at the top of the connecting component 102 can fit more closely with the structure of the fan motor mounting position and avoid interference between the connecting component 102 and the fixed parts around the fan motor, such as bolts and brackets, during the installation and disassembly of the fan motor; by setting the moving wheel 113, the friction between the base plate 101 and the inner wall of the fan duct during the movement can be reduced. In this embodiment, the moving wheel 113 is rotatably installed in the mounting groove 105 by conventional bearings in the prior art.

[0037] The connecting component 102 includes two connecting frames 106, each with an arc-shaped structure at its top. The tops of the two connecting frames 106 are connected by a support plate 103. The arc-shaped structure at the bottom of the connecting frame 106 fits more closely to the structure of the fan motor mounting position, preventing interference between the connecting component 102 and surrounding fixed components such as bolts and brackets during fan motor assembly and disassembly. The support plate 103, connected to the arc-shaped structure, can withstand concentrated loads such as the weight of the fan motor and operating forces. The loads generated by the fan motor and during operation can be laterally distributed to multiple nodes of the support frame, preventing excessive local stress from causing deformation or breakage of the connecting frame 106. Furthermore, the support plate 103 provides a mounting base for the adjustment component 104, achieving multi-functional integration.

[0038] Further optimization involves the adjustment assembly 104, which includes adjusting bolts 107 symmetrically arranged on the front and rear sides of the support plate 103. The adjusting bolts 107 are threadedly connected to the support plate 103. The four adjusting bolts 107 mounted on the two support plates 103 independently adjust the height and tilt angle. The base plate 101, equipped with casters 113, can move the fan motor, thereby enabling multi-dimensional fine-tuning of the fan in vertical lifting, horizontal translation, and angle pitch. This ensures precise alignment of the fan shaft with the transmission system during installation and disassembly, further improving assembly and disassembly efficiency. Furthermore, the four adjusting bolts 107 are arranged in a rectangular array at four points, forming symmetrical support. By adjusting the extension and retraction of different bolts, unevenness of the installation surface or foundation settlement errors can be evenly compensated, avoiding tilting caused by uneven force on one side.

[0039] The adjusting bolt 107 has a rotating block rotatably mounted on one end that contacts the fan motor. By providing the rotating block, excessive friction between the adjusting bolt 107 and the fan motor during the adjustment of the fan motor's position can be avoided, preventing wear on both the adjusting bolt 107 and the fan motor.

[0040] Further optimization involves providing a slot 108 on the base plate 101. The bulb-type turbine generator houses components such as brackets, cables, and pipelines. The slot 108 allows the base plate 101 to precisely avoid these obstacles during movement, preventing damage or jamming due to collisions. Furthermore, the slot 108 reduces the material usage of the base plate 101, lightens the overall weight, facilitates manual or small-scale mechanical handling, and lowers manufacturing costs.

[0041] The support plate 103 has ball bearings 111 mounted on its side that contacts the fan motor. When the fan motor is disassembled, rotating the adjusting bolt 107 lowers the support plate 103 to contact the ball bearings 111. The ball bearings 111 convert the sliding friction between the support plate 103 and the fan motor into rolling friction, thereby allowing the fan motor to be removed from the support plate 103 quickly and effortlessly.

[0042] Further optimization involves a limiting frame 109 fixedly connected to the base plate 101, with a limiting bolt 110 threadedly connected to the limiting frame 109 for fixing the moving wheel 113. The limiting bolt 110 is correspondingly positioned to the moving wheel 113. When the base plate 101 and connecting assembly 102 move to the position corresponding to the fan motor, rotating the limiting bolt 110 allows it to press against the moving wheel 113, thereby fixing the moving wheel 113 and the base plate 101 and preventing the base plate 101 from sliding during the installation and disassembly of the fan motor.

[0043] A handle 112 is slidably mounted on the adjusting bolt 107. In this embodiment, the adjusting bolt 107 has a through hole, and the handle 112 is slidably mounted in the through hole. The handle 112 facilitates the rotation of the adjusting bolt 107 to limit and adjust the fan motor. In actual use, when a user needs to rotate the handle 112 on the adjusting bolt 107 away from them, they can first adjust the position of the handle 112 on the adjusting bolt 107 closer to them before rotating the adjusting bolt 107 away from them. This avoids the adjusting bolts 107 on the front and rear sides of the support plate 103 blocking each other, making it difficult to rotate the adjusting bolt 107 on the inner side. In this embodiment, the left and right ends of the rotating plate are fixedly connected to stop blocks, which prevent the handle 112 from falling out of the through hole.

[0044] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
