Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a trash rack for water conservancy projects. Background Technique

[0002] A trash rack is usually a frame structure composed of side beams, cross diaphragms and grating plates; it is supported on a concrete pier wall. The trash rack is mainly arranged in front of the water inlet to block sundries such as waterweeds and driftwood carried by the water flow (generally called dirt). Excessive accumulation of dirt in front of the trash rack is likely to affect the water head and easily cause pressure on the grating plate, damaging the grating plate.

[0003] According to the Chinese patent with the publication number of CN203452967U, a trash rack for the water inlet of a water turbine generator set is disclosed. It includes a trash rack frame, a plurality of grating sheets and a plurality of grating sheet fixing plates; the trash rack frame is composed of side beams and cross beams. There are two side beams and they are vertically arranged on both sides of the trash rack frame. There are at least two cross beams and they are all horizontally arranged and fixed at both ends to the two side beams respectively. The cross section of each grating sheet is elliptical. Each grating sheet fixing plate is provided with a card slot that matches the minor axis dimension of the ellipse of the cross section of the grating sheet and the number of card slots is the same as the number of grating sheets. The grating sheets are inserted into the card slots and are vertically arranged. As the service life increases and the amount of garbage in the water increases, it may cause the inside of the water passing grooves between the grating sheets to be blocked by substances such as garbage, and blockage may occur. In view of the above problems, a trash rack for water conservancy projects is proposed to solve the above problems. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment: As Figures 1-3 shown, the present utility model provides a trash rack for water conservancy projects, including an installation frame 1. A plurality of grid plates 2 are fixedly installed on the surface of the installation frame 1. The distance between two adjacent grid plates 2 is 10 cm. Reinforcing ribs are symmetrically and fixedly installed on the other side of the installation frame 1. The provided reinforcing ribs can increase the impact resistance of the grid plates 2. Sliding grooves 3 are symmetrically formed on the surface of the installation frame 1. A slider 5 is slidably connected inside the sliding groove 3. A threaded rod is installed on the radial inner wall of the slider 5 through internal and external thread cooperation. The threaded rod rotates under the drive of a servo motor to generate an interaction force with the slider 5, so that the slider 5 drives the first cross frame 6 to slide and adjust along the sliding groove 3. A first cross frame 6 is fixedly installed between the two sliders 5. A cleaning component is provided on the surface of the first cross frame 6;

[0022] The cleaning component includes a plurality of fixing frames 12 fixedly installed on the surface of the first cross frame 6. A knocking plate 13 is fixedly installed on one side of the fixing frame 12. A sliding cylinder 7 is fixedly installed on one side of the surface of the slider 5. A spring assembly 8 is fixedly installed on one side inside the sliding cylinder 7. A sliding rod 10 is elastically connected inside the sliding cylinder 7 through the spring assembly 8. A first magnetic block is fixedly installed on one side of the bottom end of the first cross frame 6 close to one of the sliding grooves 3. A plurality of second magnetic blocks 18 are fixedly installed on the surface of the installation frame 1 close to one of the sliding grooves 3. The first magnetic block and the second magnetic blocks 18 are of the same polarity, and there is a repulsive force between the first magnetic block and the second magnetic blocks 18. When the first magnetic block and the second magnetic blocks 18 are in a vertical state during the sliding process of the first cross frame 6, under the repulsive force between the first magnetic block and the second magnetic blocks 18, the sliding rod 10 gradually moves away from the sliding cylinder 7. It should be noted that at this time, the spring assembly 8 is stretched and thus has a pulling force. When the first magnetic block and the second magnetic blocks 18 are not perpendicular, under the pulling force of the spring assembly 8 and the impact force of the water flow, the first cross frame 6 drives a plurality of knocking plates 13 to quickly face the water passing grooves between the grid plates 2 inside the trash rack.

[0023] A limiting groove 9 is formed on the surface of the sliding cylinder 7. A limiting block 11 adapted to the limiting groove 9 is fixedly installed on one side of the surface of the sliding rod 10.

[0024] During the sliding process of the sliding rod 10 inside the sliding cylinder 7, the limiting block 11 slides inside the limiting groove 9 to prevent the sliding rod 10 from sliding out of the inside of the sliding cylinder 7.

[0025] On the other side of the surface of the slider 5, a connecting rod 15 is fixedly installed, and a second cross frame 14 is fixedly installed between the two connecting rods 15. A plurality of shovel frames 16 are fixedly installed on one side of the second cross frame 14, and the shovel frames 16 are inclined downward by 35°.

[0026] The second cross frame 14 slides synchronously with the sliding of the slider 5, and the shovel frames 16 shovel the garbage and other impurities after being struck by the striking plate 13 from the water passing trough between the two grid plates 2.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
