Abstract
The utility model discloses a wind generating set convenient for maintenance. The wind generating set comprises an impeller and an engine room, wherein the hub (1) of the impeller is connected with a main shaft (21) inside the engine room; the wind generating set is characterized in that a manhole (201) for a user to enter the main shaft (2) and further enter the hub (1) through the main shaft is formed in the side wall of the main shaft (2). The wind generating set enables the worker to conveniently and safely enter the hub, and has a simple structure design.
Description
Technical field
The utility model relates to technical field of wind power generation.
Background technique
The wind-powered electricity generation unit generally is comprised of impeller and cabin, 2 ~ 3 blades are housed respectively on the impeller, in order to guarantee that wind power generating set is stable, efficiently operation, present wind-powered electricity generation unit all has the vane propeller-changing ability, and this just need to have corresponding drive unit and corresponding control section.The overall design of wind-powered electricity generation unit is generally 20 years working life now, with regard to present quality of product, be difficult to guarantee that these parts in all machine unit hubs keep normal operation during this period always, carry out corresponding examination and maintenance so just need the staff to enter into the wheel hub the inside.
General turnover wheel hub mainly contains two kinds of methods at present, the first is the space that enters into hubcap and hub body centre by the manhole between engine room cover and the hubcap, and then move forward, manhole by the wheel hub front end enters into wheel hub at last, goes out wheel hub and then returns along this path, and the advantage of this method is safer, but it is too narrow that shortcoming is the space, the ratio hub body that hubcap can not be done is large too many, and the turnover difficulty is too large, not hommization; The second is that the staff at first climbs to above the engine room cover; then open the part hubcap; step at last the manhole of hub body by the wheel hub front end and entering into wheel hub; going out wheel hub then returns along this path; the advantage of this method is that the space no longer is problem; but shortcoming is too dangerous; the hub height of main flow unit is all at seven, 80 meters height now; even the staff has the protection of safety strip in the process of turnover wheel hub; still very dangerous; personnel easily produce dizzy sense, and common people are difficult to competent such work.
Summary of the invention
The purpose of this utility model is exactly the problem that exists in order to overcome above-mentioned prior art, and a kind of wind power generating set of being convenient to safeguard is provided, so that personnel can enter wheel hub inside very convenient, safely, structural design is simple.
For realizing above-mentioned purpose of the present utility model, provide following technological scheme:
A kind of wind power generating set of being convenient to safeguard comprises impeller and cabin, and the wheel hub of impeller is connected with main shaft in the cabin, is provided with on the sidewall of described main shaft that to enter main shaft for the people inner and entered the manhole of described wheel hub inside by main shaft.
Wherein, manhole is a plurality of.
The beneficial effects of the utility model embody in the following areas:
The utility model arranges manhole at main shaft, so that the maintenance man can enter main shaft by manhole, enters wheel hub inside afterwards and by main shaft, in order to carry out maintenance work, personnel enter very convenient, safety in the wheel hub.
Description of drawings
Fig. 1 is an embodiment's of the wind power generating set of being convenient to safeguard of the present utility model structural representation.
Description of reference numerals: 1-wheel hub; The 2-main shaft; The 20-manhole; The 3-gear-box; The 4-generator.
Embodiment
Fig. 1 is an embodiment's of the wind power generating set of being convenient to safeguard of the present utility model structural representation, as shown in Figure 1, the wind power generating set of being convenient to safeguard of the present utility model comprises impeller and cabin, the wheel hub 1 of impeller is connected with main shaft 2 in the cabin, is provided with on the sidewall of main shaft 2 for the people to enter main shaft and entered the manhole 20 of described wheel hub 1 inside by main shaft.When personnel need to enter that wheel hub 1 inside checks or during maintenance work, at first with main shaft 2 lockings, personnel enter main shaft 2 by manhole 20, then enter wheel hub 1 inside by main shaft 2, so neither can the narrow and small problem of Existential Space, can there be potential safety hazard yet.
Particularly, as shown in Figure 1, impeller comprises wheel hub 1 and is installed in blade (not shown) on the wheel hub 1, and the cabin comprises: main shaft 2, and the one end is connected with wheel hub 1, so that drive main shaft 2 rotates together during wheel hub 1 rotation; The input end of gear-box 3 is connected with the other end of main shaft 2, and the output terminal of gear-box 3 is connected with generator 4, when wheel hub rotates, drives the generator rotation and generates electricity by main shaft 2, gear-box 3.
Wherein, be provided with manhole 20 on the sidewall of main shaft 2, because main shaft 2 is hollow, manhole 20 is by main shaft 2 and wheel hub 1 internal communication, and personnel can enter main shaft by manhole 20, then enter wheel hub 1 inside by main shaft 20.
The utility model can evenly arrange a plurality of manholes 20 on main shaft 2 under the prerequisite that does not affect main shaft 2 intensity.
Although above-mentioned the utility model is described in detail; but the utility model is not limited to this; those skilled in the art can make amendment according to principle of the present utility model; therefore, all various modifications of carrying out according to principle of the present utility model all should be understood to fall into protection domain of the present utility model.
Claims (2)
1. wind power generating set of being convenient to safeguard, comprise impeller and cabin, the wheel hub of impeller (1) is connected with main shaft (21) in the cabin, it is characterized in that, be provided with the manhole (20) that supplies the people to enter main shaft (2) inside and entered described wheel hub (1) inside by main shaft on the sidewall of described main shaft (2).
2. wind power generating set as claimed in claim 1 is characterized in that, described manhole (20) is a plurality of.
