Abstract

The utility model relates to a vertical sail-type windmill, belonging to the technical field of machinery. The vertical sail-type windmill designed aiming to solve the disadvantages of more investment, complex mechanisms and low benefit of the traditional propeller windmill is composed of a sail, an upper turntable, a lower turntable, a main shaft, a main shaft base, a belt pulley and a sail shaft. The vertical sail-type windmill is provided with the sail leaf which is installed on the sail leaf shaft which is evenly and vertically installed in the middle of circumferences of the upper and the lower turntables and is rotatable. The upper and the lower turntables are horizontally fixed on the main shaft. The belt pulley is horizontally fixed on the main shaft under the lower turntable. The lower end of the main which is rotatable and is vertical to the ground is installed in the main shaft base which is fixed on the ground. The utility model which has the benefitial effects and advantages of simple structure, less investment, convenience for installation and operation and high efficiency can be applied for wind power generation equipments or other power-needing equipments.

Description

Vertical sail type windmill

Technical field: the utility model relates to a kind of vertical sail type windmill, belongs to mechanical technique

Technical field.

Background technique: at present both at home and abroad the windmill that uses is propeller type, its volume is big, the device structure complexity, large-scale windmill need be built high and firm tower, for the surface of revolution that makes propeller cavitation faces wind direction, when change of the wind, the needs installation adds expensive and complicated apparatus reaches this purpose, thereby investment is many, and benefit is low.

Summary of the invention: the investment that traditional propeller type windmill exists is many, equipment mechanism is complicated, the low vertical sail type windmill that designs of benefit is made up of sail leaf, top rotary table, lower rotary table, main shaft, main shaft seat, belt pulley, sail rachis in order to solve, vertical sail type windmill is equipped with the sail leaf, the sail leaf is installed on the sail rachis, sail rachis periphery even, that be vertically mounted on top rotary table and lower rotary table is middle, rotatable, top rotary table and lower rotary table are horizontally fixed on the main shaft; Belt pulley is horizontally fixed on the main shaft of lower rotary table below; Rotatable and main shaft lower end perpendicular to the ground is installed in the main shaft seat, and main shaft seat is fixed on the ground; The utility model can be used on the equipment of wind-power electricity generation or other power requirement, simple in structure, fabric sail leaf, in light weight, can make bigger, and can be provided with many, make its output power bigger, have the beneficial effect and the advantage of little investment, easy to install, high efficiency.

Description of drawings:

Fig. 1: the front view of vertical sail type windmill;

Fig. 2: the plan view of vertical sail type windmill.

Among the figure: 1 sail leaf, 2 top rotary tables, 3 lower rotary tables, 4 main shafts, 5 main shaft seats, 6 belt pulleys, 7 sail rachises.

Embodiment:

Vertical sail type windmill is made up of sail leaf (1), top rotary table (2), lower rotary table (3), main shaft (4), main shaft seat (5), belt pulley (6), sail rachis (7); Vertical sail type windmill is equipped with sail leaf (1), sail leaf (1) is installed on the sail rachis (7), sail rachis (7) periphery even, that be vertically mounted on top rotary table (2) and lower rotary table (3) is middle, and rotatable, top rotary table (2) and lower rotary table (3) are horizontally fixed on the main shaft (4); Belt pulley (6) is horizontally fixed on the main shaft (4) of lower rotary table (3) below, and rotatable and main shaft (4) lower end perpendicular to the ground is installed in the main shaft seat (5), and main shaft seat (5) is fixed on the ground;

During use, belt pulley (6) can be connected with the equipment such as the suction engine of generator or other required drive through belt; Under the situation of facining the wind, vertical sail type windmill as shown in Figure 2: be designed to be rotated counterclockwise, for saying something, only drawn two sail leaves (1) among the figure, according to different needs, a plurality of sail leaves (1) can be set in the use; Between vertical sail type windmill sail rachis (7) and rotating disk, be added with a kind of device, no matter any wind direction, the sail rachis (7) of its left side one side sail leaf (1) is gone up when rotating from 0 °～180 ° left certainly, the sail blade face all facing the wind, sail leaf (1) faces wind sail leaf (1) face vertical with wind direction (as shown in Figure 2) in the time of 90 °, and wind is to the active force maximum of sail leaf (1) face at this moment; And the sail rachis (7) of its right one survey sail leaf (1) makes progress to the right down when rotating from 180 °～360 ° certainly, and sail leaf (1) just with the wind is sail leaf (a 1) face parallel with wind direction (as shown in Figure 1), and this moment, wind was very little to the active force of sail leaf (1) face; At this moment, vertical sail leaf windmill can be rotated counterclockwise under the effect of wind-force, reaches to drive generator for electricity generation or drive the purpose that suction engine draws water; The also available non-cloth rigidity of sail leaf (1) (hard) material is made, and this practicality row type can be used for flowing water and replaces wind-force to promote its rotation; When wind-force was excessive, the cloth sail of forming the sail leaf can partly fall or all fall, in order to avoid bad by windage loss; Need not or strange land when resettlement, remove, install easily, lose little.

Claims

1, a kind of vertical sail type windmill, form by sail leaf (1), top rotary table (2), lower rotary table (3), main shaft (4), main shaft seat (5), belt pulley (6), sail rachis (7), it is characterized in that: vertical sail type windmill is equipped with sail leaf (1), sail leaf (1) is installed on the sail rachis (7), sail rachis (7) periphery even, that be vertically mounted on top rotary table (2) and lower rotary table (3) is middle, rotatable, top rotary table (2) and lower rotary table (3) are horizontally fixed on the main shaft (4); Belt pulley (6) is horizontally fixed on the main shaft (4) of lower rotary table (3) below, and rotating main shaft (4) is perpendicular to the ground, and its lower end is installed in the main shaft seat (5), and main shaft seat (5) is fixed on the ground; Vertical sail type windmill facings the wind when being rotated counterclockwise, and meet mutually with wind direction on sail leaf (1) blade face on the left side, and sail leaf (1) blade face on the right is parallel with wind direction.

2, vertical sail type windmill as claimed in claim 1 is characterized in that: belt pulley (6) can be connected with the equipment such as the suction engine of generator or other required drive through belt.
