Abstract
The invention discloses a filter screen inside a wind turbine generator frequency converter module, belongs to the technical field of wind turbine generator accessories, and solves the problems that a wind turbine generator filter screen in the prior art is easily blocked and is inconvenient to replace due to the influence of wind sand and the like in the environment. The invention has the advantages of convenient and fast disassembly and assembly, time and labor saving and long service life.
Description
Technical Field
The invention belongs to the technical field of wind turbine generator accessory, and particularly relates to an internal filter screen of a wind turbine generator frequency converter module.
Background
The wind turbine generator system is in a severe environment, the sand storm is large, and the overtemperature phenomenon easily occurs to the frequency converter module, so that the frequency converter is in a fault shutdown state, and the generating capacity of a fan is influenced. The main reason for finding the module overtemperature through inspection is that the frequency converter cooling system has problems, mainly because the filter screen of the frequency converter module is blocked. The filter screen that converter filter screen used now is the paper filter screen, needs to change once every year, and the expense is higher. In the daily maintenance process, the paper filter screen is easy to block and deform and damage during cleaning.
Disclosure of Invention
The invention aims to:
the filter screen in the frequency converter module of the wind turbine generator is provided for solving the problems that the filter screen of the wind turbine generator in the prior art is easily blocked and inconvenient to replace due to the influence of wind sand and the like in the environment.
The technical scheme adopted by the invention is as follows:
the utility model provides an inside filter screen of wind turbine generator system converter module, includes filter screen frame, its characterized in that, filter screen frame is hollow cuboid shape, install the filter screen frame on two relative faces on the filter screen frame, the equal joint strip below of joint on filter screen frame of filter screen frame installs the filter screen on the filter screen frame, the filter screen comprises the nylon filter screen.
Further, joint strip and filter screen frame integrated into one piece, filter screen frame comprises corrosion resistant plate material, filter screen frame's corrosion resistant plate edge part is buckled 90 and is formed the joint strip.
Further, the joint strip includes long joint strip and short joint strip, long joint strip is located short joint strip top, leaves the clearance that is used for installing the filter screen frame between long joint strip and the short joint strip.
Furthermore, install on the side of filter screen frame and draw the knot, draw the knot to pass through fix with rivet on the filter screen frame.
The working principle of the invention is as follows:
according to the invention, the mounting structure that the filter screen frame is inserted into the clamping strips of the filter screen frame is adopted, the nylon filter screen is firstly fixed on the filter screen frame during mounting, after the nylon filter screen frame and the filter screen are fixed, the nylon filter screen frame and the filter screen are inserted into the gap between the long clamping strips and the short clamping strips together for fixing, and then the nylon filter screen frame and the filter screen frame are mounted into the frequency converter module of the wind power generating set, when maintenance is required, the nylon filter screen frame and the filter screen frame can be taken out by pulling the pull buckle, and the filter screen frame can be.
The tab is mounted on the stainless steel frame with a rivet.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
1. change simple and conveniently, the filter screen frame is bayonet installation, and installation and taking out are convenient and fast more than current paper filter screen, and labour saving and time saving has practiced thrift routine maintenance's time cost and human cost, and economic effect is showing.
2. The filter screen frame is light in weight, the filter screen frame is composed of thin stainless steel frames, operators can easily take the filter screen frame up and down, and the gravity load of the wind turbine generator is reduced.
3. Not being restricted by weather elements, the whole frame that the stainless steel is constituteed can effectively prevent the corrosion under the adverse circumstances, and the nylon filter screen compares in the paper filter screen, and its toughness improves by a wide margin, and is difficult for being blocked by the sand blown by the wind, adapts to open-air environment more.
4. The filter screen has the advantages of simple and effective structure, low manufacturing cost, long service life and capability of saving a large amount of cost after long-term use.
5. The service life is obviously prolonged, the whole filter screen frame does not need to be replaced, and only a local filter screen needs to be replaced when the filter screen frame is damaged.
