Description

Technical Field

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

[0002] Trash rack is a frame-type structure installed in front of the water inlet, used to block aquatic plants, driftwood and other debris (generally called trash) carried by the water flow. The trash rack is composed of a frame, a cross partition and bars, supported on a concrete pier wall, and is generally made of steel. The spacing between the bars depends on the size, amount and application requirements of the trash. The spacing of the bars used in a hydropower station depends on the model and size of the turbine to ensure that the trash passing through the trash rack will not be stuck in the flow components of the turbine. Most of the existing trash racks have fixed structures, and the finished products are customized according to preset sizes. Fixed trash racks will have the following problems: when floods occur in cities, the trash rack will not be able to adjust the size of the flow channel, resulting in a large limit on the water flow rate, and most of the existing trash racks do not have the function of removing attachments.

[0003] Therefore, it is necessary to provide a new hydraulic trash rack to solve the above-mentioned technical problems. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] See also Figures 1 to 4 An embodiment of the utility model provides a hydraulic trash rack, which includes an inclined frame 1, a fence plate 2 and a cleaning component 6.

[0024] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The top of the inclined frame 1 is fixedly mounted with a crossbeam 11, and the bottom of the inclined frame 1 is fixedly mounted with an inclined base 12, and the inclined base 12 is provided with a mounting hole 12a. The inclined frame 1 is placed in the water conservancy channel, and the inclined surface of the inclined frame 1 is kept facing the direction of the water flow, and the crossbeam 11 is erected on the top of the channel and fixed by screws, and the inclined base 12 is located at the bottom of the water conservancy channel and fixed by screws;

[0025] A plurality of rotatably connected fence plates 2 are installed in the diagonal frame 1. Specifically, a plurality of equidistantly distributed and rotatably connected rotating shafts 21 are installed in the diagonal frame 1. The plurality of fence plates 2 are respectively fixedly mounted on the plurality of rotating shafts 21, and a rotatably connected gear 3 is fixedly mounted on the shaft rod near the top of each rotating shaft 21. Adjacent gears 3 are meshingly connected, and a knob 4 is fixedly mounted on any one of the rotating shafts 21. A threaded hole connected to the axial cavity of the knob 4 is provided on the diagonal frame 1, and a threaded fixing screw 5 is inserted in the threaded hole.

[0026] It should be noted that: the rotating shaft 21 can be driven to rotate by rotating the knob 4, and since the rotating shaft 21 bracket is meshed and connected through the gear 3, the fence plates 2 on the two adjacent rotating shafts 21 rotate towards or away from each other, so the width of the flow channel formed by the two adjacent fence plates 2 on the inclined frame 1 can be quickly adjusted, so that the hydraulic trash rack can flexibly adjust the flow rate of the water flow according to the degree of pollution of the water condition;

[0027] In this embodiment, since the fence plates 2 on two adjacent rotating shafts 21 rotate toward or away from each other, the flow channel formed by the two adjacent fence plates 2 is horn-shaped, with one opening in an expanded shape and another opening in a closed shape, and the two openings are spaced apart (such as the attached Figure 4 shown).

[0028] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 A cleaning component 6 is also installed on the inclined frame 1, and the cleaning component 6 includes a cross plate 61, and the cross plate 61 is slidably installed on the inclined frame 1. Specifically, T-blocks 62 are fixedly installed on both sides of the cross plate 61, and the two T-blocks 62 are respectively inserted into the T-shaped slide grooves 1a opened on the two side walls of the front end surface of the inclined frame 1 and are slidably connected with the T-shaped slide grooves 1a, and a plurality of cleaning rake teeth 63 are fixedly installed on the inner plate wall of the cross plate 61, and the cleaning component 6 also includes a dual-axis motor 64, the dual-axis motor 64 is installed on the inclined frame 1, and the output ends on both sides of the dual-axis motor 64 are fixedly installed with pulleys 65, a steel wire rope 66 is wound around the pulley 65, and the other end of the steel wire rope 66 is fixedly connected to the upper plate edge of the cross plate 61, and the dual-axis motor 64 is fixedly installed on the top of the beam 11 through a frame.

[0029] It should be noted that: when it is necessary to clean the debris blocked by the fence plate 2, the knob 4 is turned to reduce the width of each flow channel, and the wire rope 66 is pulled on the double-axis motor 64, so that the cross plate 61 slides up along the outer inclined surface of the inclined frame 1 along with the T-block 62. Therefore, the cleaning rake teeth 63 in the cross plate 61 can rake and clean the attached debris, and the cleaning rake teeth 63 can scrape off a large area of ​​debris attached to one side of the trash rack to prevent such debris from affecting the water conveying effect of the trash rack.

[0030] The working principle of the hydraulic trash rack provided by the utility model is as follows:

[0031] The rotating shaft 21 can be driven to rotate by rotating the knob 4. Since the rotating shaft 21 bracket is meshed and connected by the gear 3, the fence plates 2 on the two adjacent rotating shafts 21 rotate toward or away from each other. Therefore, the width of the flow channel formed by the two adjacent fence plates 2 on the inclined frame 1 can be quickly adjusted, so that the hydraulic trash rack can flexibly adjust the flow rate of the water flow according to the degree of pollution of the water condition. When it is necessary to clean the debris blocked by the fence plates 2, the knob 4 is rotated to reduce the width of each flow channel, and the steel wire rope 66 is pulled on the dual-axis motor 64, so that the cross plate 61 slides along the outer inclined surface of the inclined frame 1 with the T-block 62. Therefore, the cleaning rake teeth 63 in the cross plate 61 can rake and clean the attached debris, and the cleaning rake teeth 63 can scrape off a large area of ​​debris attached to one side of the trash rack to prevent such debris from affecting the water conveying effect of the trash rack.

[0032] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
