Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.

As shown in fig. 1 and 2, the trench device for preventing deposition of silt of the present invention comprises a trench body 1, a trench grid cover plate 2 installed on the trench body 1, a rinsing water pipe 3 and a plurality of rinsing nozzles 4 installed in the trench body 1.

The top of the trench body 1 is provided with a cover plate groove 11 for matching with the trench grating cover plate 2. The trench grating cover plate 2 is directly placed in the cover plate groove 11, so that the trench grating cover plate 2 can be conveniently lifted to overhaul the trench device.

The trench body 1 is provided with an arc bottom surface 12 at the bottom, and the bottom surface 12 is designed into an arc shape, so that the flowing resistance of slurry in the trench is reduced, the flowing of the slurry in the trench is facilitated, and the slurry siltation is reduced.

Because the utility model discloses a prevent becoming silted up ground slot device's 12 designs for the arc, has reduced the resistance that the trench thick liquid flows, therefore is favorable to the trench thick liquid to flow, reduces the thick liquid siltation.

The utility model discloses a prevent becoming silted up ground slot device design is nimble, simple structure, the installation of being convenient for. Furthermore, the utility model discloses still carried out a series of innovative transformation to the problem of the easy siltation of current trench, drop into low, the security is good, economic nature is showing, can wide application to have succinctly effective, easily promote, the effect is showing characteristics.

The bottom surface 12 is also sloped so that it is higher and lower in the direction of slurry flow in the trench means, so that the bottom surface 12 is also sloped. The arc-shaped bottom surface 12 with the slope is further beneficial to the flow of slurry in the trench and reduces slurry siltation.

The trench body 1 further has two opposite side surfaces 14, 16, and the two side surfaces 14, 16 are both planar and parallel to each other.

The washing water main pipe 3 is arranged in the trench body 1 and is positioned at the bottom of the trench body, the whole washing water main pipe is approximately arranged in a U shape, wherein two long parallel sections of the washing water main pipe 3 are arranged close to two opposite side surfaces 14 and 16 of the trench body 1, and the middle section of the washing water main pipe 3 is arranged above a higher position corresponding to the arc-shaped bottom surface 12 of the trench body 1.

The flushing nozzles 4 are connected to the flushing water header 3 and are spaced apart from each other in the direction in which the flushing water header 3 extends in a U-shape. Wherein, a part of the washing nozzles 4 connected with two parallel sections of the washing water main pipe 3 are arranged close to two opposite sides of the bottom of the trench body 1 in a staggered way, so that the arrangement reduces the use amount of washing water while slurry is deposited in the trench; the other part of the washing nozzle 4 connected to the middle section of the U-shaped washing water main pipe 3 is arranged above the position corresponding to the higher part of the arc-shaped bottom 12 of the trench body 1, so that the washing water sprayed from the washing nozzle 4 flows along the higher part of the arc-shaped bottom 12 of the trench body 1 to the lower part, and the slurry deposited in the trench is easier to remove.

Fig. 3 is a schematic top view of the trench device for preventing silting up according to another embodiment of the present invention, which is different from the above embodiments: the two opposite and

parallel sides

14a, 16a of the anti-siltation trench means are curved and form an arcuate corner. The corner of the trench device is designed into an arc-shaped corner, and compared with the right-angled corner of the trench in the prior art, the arc-shaped corner reduces the flowing resistance of slurry in the trench, thereby being beneficial to the flowing of the slurry in the trench and reducing the slurry deposition.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
