Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing cooling, specifically a bearing cooling device for a hydro-generator set. Background Technology
[0002] A hydro-turbine generator set is a device that uses the mechanical energy of water flow to convert it into mechanical energy through a water turbine, and then converts the mechanical energy into electrical energy through a generator. It is one of the core devices of hydropower generation and is widely used in hydropower stations. Its working principle is based on the principle of water energy conversion, that is, the kinetic or potential energy of water flow drives the generator to generate electrical energy through the water turbine.
[0003] According to application number 202322094118.2, a circulating cooling device for a hydro-generator bearing is disclosed, including a base plate, an air pump fixedly mounted on the top of the base plate, and a first air pipe fixedly mounted on the air inlet of the air pump. The beneficial effects of this utility model are: when the bearing overheats and the cooling efficiency of the cooling pipe decreases, the air pump is started. The air pump discharges the hot air near the bearing into the water tank through the air inlet bucket, the first air pipe and the second air pipe, so that the hot air directly exchanges heat with the water, improving the cooling efficiency of the hot air. The cooled gas returns to the vicinity of the bearing through the third air pipe and the exhaust bucket, and exchanges heat with the bearing, improving the cooling efficiency of the bearing. The second water pump and the drain valve are started. The second water pump allows external water to enter the water tank, while the water in the water tank is discharged through the fifth water pipe, so that the water in the water tank always maintains a low temperature, improving the cooling effect on the bearing.
[0004] The above-mentioned solution still has certain shortcomings in actual use. After a long period of filtration, the surface of the filter plate will be covered with filtered impurities. The long-term accumulation will affect the filtration effect of the filter plate on water resources. The filter plate in the above solution cannot be removed, which will affect the subsequent normal heat dissipation effect on the bearing after long-term use, thus reducing the practicality of the device. Therefore, we provide a water turbine generator bearing cooling device. Utility Model Content

[0014] (III) Beneficial Effects
[0015] This utility model provides a bearing cooling device for a hydro-generator set. It has the following beneficial effects:
[0016] This hydro-generator bearing cooling device, through the coordinated arrangement of cooling and filtration components, enables the cooling components to dissipate heat from the bearings, ensuring their normal operation.

First, the two circular plates are pulled away from each other. During this process, the locking blocks slowly disengage from the locking holes, releasing the restriction on the pull plates. Then, the operator pulls the pull plate, utilizing the connection between the locking posts and the filter plates to pull both the pull plate and the filter plates out together. This facilitates the disassembly of the filter plates, making subsequent cleaning easier and ensuring that the filtration effect of the filter plates is not affected, nor is the normal heat dissipation effect on the bearings, thus improving the practicality of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1-6 As shown, this utility model provides a technical solution: a bearing cooling device for a hydro-generator set, including a base plate 1, a cooling assembly 2 installed on the upper surface of the base plate 1, the cooling assembly 2 including a pump 201, the pump 201 is installed on the upper surface of the base plate 1, the input end of the pump 201 is connected to an input pipe 202, the output end of the pump 201 is connected to an output pipe 203, and the other end of the output pipe 203 is connected to the outer surface of a filter box 3. The pump 201 can extract water resources, thereby facilitating subsequent normal use. At the same time, the filter box 3 can store water resources, ensuring the normal utilization of water resources by subsequent devices.
[0027] The cooling assembly 2 also includes a water storage tank 204, the bottom surface of which is fixedly connected to the upper surface of the base plate 1. A connecting pipe 205 connects the filter box 3 and the water storage tank 204. The water storage tank 204 can store the filtered water resources, which facilitates subsequent normal use. At the same time, the connecting pipe 205 can transport water to the inside of the water storage tank 204, which facilitates subsequent work.
[0028] The cooling assembly 2 also includes a connecting pump 206, which is installed on the upper surface of the base plate 1. The input end of the connecting pump 206 is connected to a short pipe 207, and the other end of the short pipe 207 is connected to the outer surface of the water storage tank 204. The output end of the connecting pump 206 is connected to a cooling pipe 208, and the other end of the cooling pipe 208 is connected to the outer surface of the water storage tank 204. The connecting pump 206 can extract water from the water storage tank 204, thereby enabling the flow of water inside the cooling pipe 208 and thus achieving heat dissipation for the bearing.
[0029] A filter box 3 is fixedly connected to the upper surface of the base plate 1. A filter assembly 4 is installed on the upper surface of the base plate 1. The bottom surface of the filter assembly 4 is fixedly connected to the upper surface of the base plate 1. The filter assembly 4 includes two mounting plates 401. Both mounting plates 401 are installed on the inner wall of the filter box 3. A filter plate 402 is slidably connected between the two mounting plates 401. The filter plate 402 can filter water resources and ensure the normal use of water resources in the future.
[0030] A pull plate 403 is snapped onto the upper surface of the mounting plate 401, and a handle 404 is fixedly connected to the upper surface of the pull plate 403. The handle 404 allows the pull plate 403 to be pulled out easily, ensuring the effectiveness of the pull plate 403 in subsequent use.
[0031] The pull plate 403 has locking holes 405 on both its left and right sides. The inner walls of the two locking holes 405 are fitted with locking blocks 406. A slide rod 407 is fixedly connected to one side of each of the two locking blocks 406. The outer surfaces of the two slide rods 407 are slidably connected to the outer surface of the filter box 3. A circular plate 408 is fixedly connected to the side of the two slide rods 407 that are far apart from each other. A spring 409 is installed between the circular plate 408 and the locking block 406. Through the locking between the locking holes 405 and the locking blocks 406, and with the spring 409 providing a certain degree of reset capability for the slide rods 407, the locking blocks 406 and the locking holes 405 are locked more closely, which can ensure the subsequent use effect of the pull plate 403.
[0032] The bottom surface of the pull plate 403 is fixedly connected to two connecting frames 410. Each of the two connecting frames 410 has a set of hinge blocks 411 hinged inside. A connecting spring 412 is installed between the hinge block 411 and the connecting frame 410. The connecting spring 412 can provide a certain elastic force to the hinge block 411, which can ensure the subsequent use effect of the hinge block 411.
[0033] Each set of hinge blocks 411 has a locking post 413 fixedly connected to one side of each other, and the locking post 413 is in contact with the outer surface of the filter plate 402. The outer surface of the locking post 413 is engaged with the hole of the filter plate 402, which can make it easier for the staff to remove the pull plate 403 later.
[0034] Working principle:
[0035] When disassembling the filter plate 402, first pull the two circular plates 408 in a direction away from each other. During the pulling process, the locking block 406 will slowly disengage from the inside of the locking hole 405, thereby releasing the restriction on the pull plate 403. Then, the operator can pull the pull plate 403 upwards using the handle 404. During the pulling process, the connection between the locking post 413 and the filter plate 402 can be used to pull out the pull plate 403 and the filter plate 402 together, thus realizing the disassembly of the filter plate 402. This facilitates the subsequent cleaning of the filter plate 402 and will not affect the filtration effect of the filter plate 402 or the normal heat dissipation effect on the bearing, thereby improving the practicality of the device.
