Description

Technical Field

[0001] The utility model relates to river channel management, in particular to a trash rack. Background Art

[0002] Trash rack is a tool commonly used in the process of river management. The two ends of the trash rack are connected to the two banks of the river, part of it is sunk into the river and part of it is exposed. In this way, the garbage floating on the river surface will be intercepted and piled up by the trash rack as it flows with the water. The existing trash rack generally includes two connecting parts and a trash net arranged between the two connecting parts. Although such a trash rack can be easily adapted to the width of the installation position of the river, the stability is relatively general. Especially when the width of the installation position of the river is relatively large, it is generally necessary to install a number of piles for the trash net to connect in the river, and the operation is relatively complicated and cumbersome. Therefore, the existing trash rack also includes a rectangular frame surrounded by channel steel and a trash net arranged on the frame, which has better stability. However, during installation, since the size of the rectangular frame is fixed, the width of the installation position of the river generally has a considerable measurement error, resulting in the need for various adjustments during installation. It can be seen that the existing trash rack still has the problem of not being able to take into account both high stability and convenience of installation. Utility Model Content

[0023] The following is further explained in conjunction with the accompanying drawings. Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] See also Figure 1 , a trash rack comprises: two first channel steels 1 and a plurality of trash rack sections 2.

[0025] The two first channel steels 1 are both horizontal and arranged one above the other. The notches of the two first channel steels 1 face each other.

[0026] The multiple trash rack sections 2 are installed between two channel steels, that is, the upper part and the lower part of each trash rack section 2 are installed in the notches of the two channel steels respectively.

[0027] See also Figure 2 , Figure 3 and Figure 5 Each trash rack section 2 includes: two second channel steels 2a, a trash net 2b and a plurality of flat steels 2c.

[0028] The two second channel steels 2a are both vertical and arranged one on the left and one on the right. The notches of the two second channel steels 2a face each other, so that the two second channel steels 2a can fit together between two adjacent trash rack sections 2.

[0029] The vertical edges on both sides of the trash net 2b are fixed to the two second channel steels 2a respectively. Specifically, the vertical side plates of the two second channel steels 2a can have a plurality of through holes, and the vertical edges of the trash net 2b are tied and fixed to the second channel steels 2a by steel wires.

[0030] One side vertical edge of the plurality of flat steels 2c is fixedly connected to the trash-blocking net 2b, and specifically, can also be fixed by steel wire binding.

[0031] The width of the second channel steel 2a is equal to the width of the notch of the first channel steel 1; the two ends of the second channel steel 2a are respectively fixedly connected to the notches of the two first channel steels 1, and the two can be fixed by welding. The width of the flat steel 2c is smaller than the width of the notch of the first channel steel 1; the two ends of the flat steel 2c are also respectively fixedly connected to the notches of the two first channel steels 1, and the two can be fixed by welding.

[0032] Thus, when manufacturing the trash rack, for the trash rack sections 2 at both sides, the second channel steel 2a on the inner side can be first fixedly connected to the two first channel steels 1, and the other second channel steel 2a on the outer side and the plurality of flat steels 2c can be first not fixedly connected to the two first channel steels 1. When the trash rack is installed in the river channel, the positions of the second channel steels 2a at the two sides can be first adjusted inwards to adapt to the installation position on the river channel; then the two second channel steels 2a are fixedly connected to the two first channel steels 1; then the positions of the flat steels 2c are adjusted to keep the trash rack 2b straight; finally, the flat steels 2c are fixedly connected to the two first channel steels 1.

[0033] See also Figure 6 Optionally, for the trash rack sections 2 at both sides, both ends of each flat steel 2c are provided with connecting pieces 3 connected to the corresponding first channel steels 1, so that the flat steel 2c can be adjusted in the fixed position of the two first channel steels 1 in the longitudinal and transverse directions.

[0034] Specifically, the end of the flat steel 2c may be provided with a first waist-shaped through groove 2c11a, the connecting member 3 may be provided with a notch for the end of the flat steel 2c to enter, and may also be provided with a first bolt 3a that passes through the first waist-shaped through groove 2c11a and can press and fix the connecting member 3 to the flat steel 2c; the first channel steel 1 may be provided with a second waist-shaped through groove, and the connecting member 3 may also be provided with a second bolt 3b that passes through the second waist-shaped through groove and can press and fix the connecting member 3 to the first channel steel 1. In this way, the position adjustment and fixing of the flat steel 2c are more convenient.

[0035] Furthermore, for the remaining trash rack sections 2 , both ends of each flat steel 2 c are also provided with connecting pieces 3 for connecting with the corresponding first channel steel 1 .

[0036] See also Figure 4 Optionally, both ends of the second channel steel 2a at both sides are provided with concave portions 2a1 to form slots for the first channel steel 1 to be inserted into, and the concave portions 2a1 are also provided with third bolts 2a2 that can fix the second channel steel 2a to the first channel steel 1.

[0037] In this way, the positions of the two second channel steels 2a can be adjusted and fixed more conveniently.

[0038] Furthermore, both ends of the remaining second channel steels 2a are also provided with concave portions 2a1 and first bolts 3a.

[0039] Combined with the above-mentioned setting that "each flat steel 2c also has a connecting piece 3 connected to the corresponding first channel steel 1 at both ends", the multi-section trash rack segment 2 can be disassembled and installed from the two first channel steels 1. The disassembled trash rack segment 2 can be folded and gathered, and the trash net 2b and the multiple flat steels 2c are all gathered in the notches of the two second channel steels 2a, thereby reducing the size of the trash rack and facilitating transportation.
