[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] As shown in the figure, a dust collecting device for a hydro-turbine generator includes a housing 1 and an opening and closing door (not shown) installed at the front opening of the housing 1. Two oppositely arranged connecting plates 2 are fixedly connected horizontally on the left and right sides of the housing 1. A generator 3 is installed on the upper side of the two connecting plates 2. A V-shaped dust collecting hopper 4 is connected to the lower side of the two connecting plates 2. An adsorption fan 5 is connected to the lower outlet of the dust collecting hopper 4. A baffle 6 is fixedly connected between the two sides of the dust collecting hopper 4 and the bottom of the housing 1. The rear ends of the connecting plates 2, the collecting hopper and the baffle 6 are all against the rear side wall of the housing 1, and the front ends are all against the opening and closing door. A dust collecting bin 7 is surrounded by the two baffles 6, the dust collecting hopper 4, the rear side wall of the housing 1 and the opening and closing door, and an air inlet 101 is opened at the top of the housing 1. An exhaust port 102 is provided on the rear side wall of the housing 1 corresponding to the dust collecting bin 7. In this embodiment, connecting edges are horizontally provided on the top of both sides of the dust collecting hopper 4, which are fixedly connected to the bottom of the corresponding connecting plate 2 by bolts 11. Start the adsorption fan 5, and the air flow enters the shell 1 from the air inlet 101. The dust generated by the generator 3 enters the dust collecting hopper 4 along with the air flow, and then enters the dust collecting bin 7. The baffle 6 is fixed between the two sides of the collecting hopper and the bottom of the shell 1. On the one hand, the collecting hopper is supported by the baffle 6 to ensure the installation stability of the collecting hopper. On the other hand, a separate dust collecting bin 7 space is enclosed by the rear side wall of the shell 1, the two baffles 6, and the opening and closing door, which is convenient for the dust to land after passing through the adsorption fan 5, and also reduces the space of the dust collecting bin 7 to a certain extent, which is convenient for later cleaning.

[0024] The dust collecting hopper 4 is filled with a first filter cotton 9 for preliminarily filtering the dust generated when the hydro-generator 3 is working, thereby reducing the influence on the adsorption fan 5 .

[0025] An isolation mesh frame 8 is horizontally inserted between the two connecting plates 2. The isolation mesh frame 8 includes a connecting frame 801 and a plurality of connecting rods 802 fixedly connected to the inner side of the connecting frame 801 and staggered in a horizontal and vertical direction. The isolation mesh frame 8 is used to block the first filter cotton 9 in the dust hopper 4 to prevent the first filter cotton 9 from being drawn into the generator 3 from between the two connecting plates 2. Grooves 201 are opened on the two connecting plates 2 at positions corresponding to the isolation mesh frame 8, and the isolation mesh frame 8 is inserted between the two grooves 201.

[0026] A shielding net 12 located above the adsorption fan 5 is provided in the lower outlet of the dust hopper 4 to prevent the first filter cotton 9 in the dust hopper 4 from being drawn into the adsorption fan 5 .

[0027] Vibrators 10 are installed on the upper sides of the two connecting plates 2 for generating vibrations so that the dust generated by the generator 3 can fall off and enter the dust collecting hopper 4 .

[0028] A pressure cover 14 is screwed on the upper side of the air inlet 101, a hollow hole 1401 is opened in the middle of the upper surface of the pressure cover 14, and a filter screen 15 is pressed between the inner side of the pressure cover 14 and the upper end of the air inlet 101 to prevent the external airflow from bringing in large debris when entering the shell 1.

[0029] A filter 13 with a second filter cotton is installed at the air outlet 102 to prevent the dust in the dust collecting bin 7 from being dispersed into the external environment along with the air flow.

[0030] In this embodiment, the rotating shaft of the hydro-generator 3 is disposed through the housing 1 and is connected to the water wheel in the external water wheel box.

[0031] The working process of this embodiment is as follows:

[0032] When the generator 3 is working, the adsorption fan 5 and the vibrator 10 are started, the vibrator 10 vibrates to make the dust attached to the generator 3 separate from the generator 3, and the air flow enters the shell 1 from the air inlet 101. The dust generated by the generator 3 enters the dust hopper 4 with the air flow, and is preliminarily filtered by the first filter cotton 9 in the dust hopper 4, and then enters the dust collecting bin 7. Finally, the air flow is discharged from the filter 13 on the rear side of the dust collecting bin 7, and the dust is blocked in the dust collecting bin 7.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
