Technical Field

[0001] The utility model relates to the technical field of road drainage, in particular to a spliced drainage trough for highway engineering. Background Art

[0002] Road drainage is a facility that is used in conjunction with road engineering to remove rainwater, snowwater, urban wastewater, groundwater from the road surface and the ground, and to lower the groundwater level. It is an important part of road engineering. The more common road drainage method is to dig a ditch along the road direction on both sides of the road, lay drainage grooves in the ditch, and cover the drainage grooves with grilles. However, this type of drainage groove has a simple structure and is prone to clogging when in use.

[0003] Existing drainage gutters, such as a highway engineering drainage trough with technical disclosure number CN219118318U, have a filter screen installed in the drainage trough to separate sewage from impurities such as fallen leaves. However, when the drainage trough is in use, fallen leaves and other debris tend to accumulate at the drainage outlet of the cover plate, causing blockage. Moreover, after the filter screen of the device separates sewage from fallen leaves and other impurities, fallen leaves and other debris still remain on the filter screen and accumulate, still causing blockage, preventing sewage from flowing normally under the filter screen. Utility Model Content

[0004] The purpose of the utility model is to make up for the shortcoming of the prior art that it is easy to be blocked, and to provide a spliced drainage trough for highway engineering.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-5 As shown, the utility model provides a technical solution: a spliced drainage trough for highway engineering, comprising a trough body 1, the front and rear sides of the trough body 1 are both open, and the cross-section is U-shaped, the top of the trough body 1 near the left and right sides are integrally fixedly connected with scrapers, a cover plate 2 is provided on the top of the trough body 1, the cover plate 2 near the left and right sides and on the scraper are provided with through holes, the cover plate 2 is provided with bolts, and the bolts pass through the two through holes in sequence, and a drainage port is provided on the cover plate 2, the bottom of the trough body 1 near the front side and the inner wall of the bottom of the trough body 1 near the rear side are provided with card slots, and two adjacent trough bodies 1 can be connected to each other through the card slots, and a sealing strip 101 is fixedly connected in the card slot located on the inner side of the trough body 1.

[0022] According to the overall structure of the device, when in use, multiple trough bodies 1 are placed in a pre-dug ditch, laid along the ditch, and two adjacent trough bodies 1 are connected by a card slot, so that the drainage trough is tightly connected to avoid the separation of the drainage trough affecting the drainage effect, and the card slot is sealed by a sealing strip 101 to prevent sewage from leaking out of the drainage trough and affecting the roadbed structure. Then, the cover plate 2 is placed on the trough body 1, and the cover plate 2 and the trough body 1 are connected by bolts, and the bolts are driven into the ground to fix the trough body 1 and the cover plate 2 to prevent loosening. When draining, rainwater on the road surface flows to the cover plate 2 and flows into the trough body 1 from the drain outlet and is discharged.

[0023] like Figure 3 As shown, the cover plate 2 includes a fixed plate 201, a slot is provided on the fixed plate 201, and a movable plate 202 is movably connected in the slot, a drain outlet is provided on the movable plate 202, and a plurality of movable plates 202 are provided. The plurality of movable plates 202 are linearly arranged from front to back, and are evenly divided into a group with two adjacent movable plates 202, and two adjacent movable plates 202 in different groups are set opposite each other.

[0024] The cover plate 2 is composed of a fixed plate 201 and several movable plates 202, and the movable plates 202 are movably connected in the slots of the fixed plate 201, so that the cover plate 2 can be opened by flipping the movable plates 202, so that the blockage on the cover plate 2 falls down, thereby quickly clearing the blockage.

[0025] like Figure 3 As shown, a frame 3 is provided in the slot, and the frame 3 is located above the movable plate 202. The frame 3 is slidably connected to the cover plate 2, and the frame 3 is transmission-connected to the movable plate 202. A gear 5 is provided at the connection between the movable plate 202 and the slot, and the gear 5 is fixedly connected to the movable plate 202. A vertical plate 6 is fixedly connected to the bottom of the frame 3, and tooth grooves are provided on the front and rear sides of the vertical plate 6. The vertical plate 6 is engaged with the adjacent gear 5.

[0026] The sewage accumulates above the cover plate 2 and generates pressure on the frame 3, causing the frame 3 to move downward. When the frame 3 moves downward, the vertical plate 6 and the gear 5 drive the movable plate 202 to flip, thereby opening the cover plate 2, so that the fallen leaves and other debris accumulated on the cover plate 2 can fall into the trough 1, thereby achieving automatic dredging.

[0027] like Figure 4 As shown, T-shaped vertical rods 7 are fixedly connected to the bottom of the frame 3 near the four corners, the cover plate 2 is provided with openings, and the vertical rods 7 are inserted into adjacent openings, and springs 9 are fixedly connected between the bottom of the vertical rods 7 and the openings.

[0028] When the frame 3 moves downward, the spring 9 is compressed by the vertical rod 7. When the sewage is discharged, the pressure above the frame 3 disappears, and the elastic force of the spring 9 pushes the frame 3 upward to reset, and drives the movable plate 202 to flip and reset, closing the cover 2.

[0029] like Figure 3 As shown, a sleeve 8 is fixedly connected between the frame 3 and the cover plate 2, and the sleeve 8 is sleeved on the outside of the vertical rod 7. A blocking curtain 4 is fixedly connected to the bottom of the frame 3 near the inner edge. The blocking curtain 4 and the sleeve 8 are both made of elastic rubber.

[0030] The sleeve 8 is sleeved on the outside of the vertical rod 7 to isolate the vertical rod 7 and the opening from the outside world, preventing foreign matter from entering the opening and jamming the spring 9, thereby affecting the up and down movement of the frame 3. The blocking curtain 4 restricts fallen leaves and other debris to the inside of the blocking curtain 4, thereby preventing foreign matter from following the water flow into the gear 5 and causing the gear 5 to get stuck.

[0031] Working principle: When in use, multiple trough bodies 1 are placed in a pre-dug ditch and laid along the ditch. Two adjacent trough bodies 1 are connected by means of a card slot, so that the drainage trough is tightly connected to avoid separation of the drainage trough affecting the drainage effect. The card slot is sealed with a sealing strip 101 to prevent sewage from leaking out of the drainage trough and affecting the roadbed structure. Then, the cover plate 2 is placed on the trough body 1, and the cover plate 2 and the trough body 1 are connected by bolts, and the bolts are driven into the ground to fix the trough body 1 and the cover plate 2. To prevent loosening, when draining, rainwater on the road flows to the cover plate 2 and flows into the trough body 1 from the drain outlet. When fallen leaves accumulate above the cover plate 2 and cause blockage, sewage will accumulate above the cover plate 2, generating pressure to push the frame 3 down, thereby driving the movable plate 202 to flip over and open the cover plate 2. At this time, fallen leaves and other debris can fall into the trough body 1, unblocking the top of the cover plate 2, and sewage can flow smoothly into the trough body 1. After the sewage is drained, the frame 3 drives the movable plate 202 to reset under the action of the spring 9.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
