Description

A new type of water generator

technical field

The invention relates to a novel water flow generator, in particular to a tubular new water flow generator. the

Background technique

The hydroelectric generator is an energy-saving and environmentally friendly product. The hydraulic generator on the urban water pipe network uses pressurized water to directly drive the impeller. The impeller drives the rotating shaft of the rotor to rotate, and the rotating shaft drives the rotor to rotate. The coil of the stator cuts the magnetic field lines to generate current and generate electricity. The current can be applied to household appliances after treatment. the

However, the products on the market have the following defects: ①Because the copper-based oil-impregnated bearing belongs to sliding friction and requires a large gap, if the gap is too large, it will affect the overall stability of the product. The bottom is supported by stainless steel balls, and the balls will wear out after a long time of operation , so as to increase the movement of the internal rotor. ②Water will easily enter the inside of the motor, induce rust on metal parts such as magnets, claw poles, and bearings, and shorten the life of the enameled wire. ③The current and voltage are unstable. The four-level magnetic steel runs through the line of cutting magnetic force, and the current and voltage generated are unstable, and ④ the life is short. In addition, ordinary motors (1) use copper-based powder oil-impregnated bearings and steel balls, resulting in center deviation and up and down movement; (2) easy water ingress to induce metal parts to rust; (3) poor material properties and easy deformation, resulting in a short service life of the motor. Therefore, in order to meet the requirements of urban use, it is necessary to provide a new type of hydroelectric generator, which meets the needs of use, is low-carbon and environmentally friendly, and has a long service life. the

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a new water flow generator. This product converts the kinetic energy of water into electric energy, reutilizes the originally wasted resources, and can replace induction faucets, urinals, irrigation Such as start-up power; shower, shower room LED power supply; electronic water meter power supply, etc.; when used in sensor faucets combined with high-performance batteries, it can play a self-sufficient role instead of disposable batteries currently on the market. Responding to the low-carbon energy saving and green environmental protection promoted by the country. The defects and deficiencies of ordinary motors are improved, so that the service life is increased and the performance is stable. the

The present invention provides a novel hydroelectric generator, comprising a body (7) and a tee (8),

The body (7) has upper bearing (10), impeller (9), upper cover (1), middle bearing (2), magnet (4), lower bearing (5), lower cover (6),

The exterior of the magnet (4) has a skeleton (3),

The upper bearing (10), the impeller (9), the middle bearing (2), and the lower bearing (5) are connected to form a rotor through a shaft (11),

At least one of the upper bearing (10), the middle bearing (2) and the lower bearing (5) adopts a ball bearing. the

In another preferred example, all three of the upper bearing (10), the middle bearing (2) and the lower bearing (5) are ball bearings. the

In another preferred example, the tee (8) has a water guiding channel, and the water inlet and water outlet of the water guiding channel are not on a straight line. the

The new water current generator in the present invention adopts ball bearings, which effectively reduces the friction between the shaft and the bearing, and can also ensure the axial movement of the shaft and the center position of the shaft. No matter the temperature resistance, pressure resistance, wear resistance, etc. have been significantly improved. The design of the new water flow generator in the present invention is different from that of ordinary motors. The design of the water inlet and outlet of the tee is not on a straight line to ensure that the water inlet and outlet are not hindered. The installation of the motor on the water pipe will not have any impact on the size of the water flow. Solved the problem of low flow of terminal utilities. The advantages of the novel water current generator in the present invention in terms of design, material, process, etc. are that the life of the motor is 5-10 years, which is significantly improved compared with the same type of motor. the

It should be understood that within the scope of the present invention, each of the above-mentioned technical features of the present invention and each of the technical features specifically described below can be combined with each other to form a new or preferred technical solution. Due to space limitations, we will not repeat them here. the

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings. the

Fig. 1 is a schematic diagram of the cross-sectional structure of the novel hydroelectric generator of the present invention. Referring to FIG. 1 , the present invention is a novel hydroelectric generator, including a body 7 and a tee 8 . In Fig. 1, water enters from above, and water is discharged from below, body 7 has upper bearing 10, impeller 9, loam cake 1, middle bearing 2, magnet 4, lower bearing 5, lower cover 6 from left to right. The outside of the magnet 4 has a skeleton 3 . Upper bearing 10, impeller 9, middle bearing 2, lower bearing 5 are connected into rotor by shaft 11. the

According to different practical environments and practical requirements, the new type of water current generator adopts different materials for the corresponding parts to achieve the best performance. For example, the magnet 4 can be a high-performance magnetic steel. In this case, the magnet has a large magnetic force and can generate a highly stable current and voltage when rotating. the

At least one of the upper bearing 10, the middle bearing 2, and the lower bearing 5 adopts a ball bearing. Of course, it is also possible for all three to adopt a ball bearing. the

FIG. 2 is a plan view of the tee 8 viewed from the right side of FIG. 1 . Tee 8 has a water guide channel. As shown in Fig. 2, the water inlet and the water outlet of the water guiding channel are arranged not in a straight line. In the existing generators, the water inlet and outlet are usually arranged on a straight line. In this way, a large amount of water will not impinge on the main body of the generator to generate power, thereby reducing the power generation efficiency. However, in the present invention, since the water inlet and outlet are arranged not on a straight line, compared with the existing generator, the power generation efficiency can be increased by about 15%. the

The working principle of the novel water flow generator of the present invention is: water enters the generator through the water inlet, impacts the impeller 9, and transmits a part of kinetic energy to the generator, drives the impeller 9 and the magnet 4 to rotate at a high speed, and then flows out through the water outlet; the magnet 4 rotates , the coil around the magnet 4 converts kinetic energy into electrical energy by cutting the magnetic field lines, and generates a high-stability current and voltage. the

Of course, the above description is only one embodiment of the present invention, and it should be pointed out that for those skilled in the art, some improvements and modifications can also be made without departing from the principles of the present invention. , These improvements and modifications all belong to the scope of protection of the claims of the present invention. the
