Description

Technical Field

[0001] The utility model relates to the technical field of drainage ditches, in particular to a prefabricated drainage ditch for community reconstruction construction. Background Art

[0002] Drainage ditch refers to the ditch that diverts water collected in side ditches, intercepting ditches and low-lying areas near roadbeds, crops and houses to outside the roadbeds, crops and houses, while prefabricated drainage ditch is an integral drainage ditch prepared in advance by pouring concrete, which is then transported to the installation site for installation and construction. It has the characteristics of short construction time and high efficiency. With the development of time, the environment of old residential areas gradually cannot meet the living requirements, so the old residential areas need to be renovated, and during the renovation process, the drainage system also needs to be renovated.

[0003] Common prefabricated drainage ditches are mostly U-shaped grooves with a grid cover on top of the groove. However, during use, silt, fallen leaves, or domestic garbage often enter the drainage ditch, causing blockage of the drainage ditch and even a foul odor, affecting the environment in the community. Therefore, prefabricated drainage ditches for filtering to avoid blockage and improve drainage efficiency have emerged. However, after long-term use, the filter holes on the inner wall of the existing device will be blocked by silt, which will affect the filtering effect. The cleaning inside the hole is relatively cumbersome, time-consuming and labor-intensive, which seriously affects the use effect. For this reason, we designed a prefabricated drainage ditch for community renovation construction to solve the above technical problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In this device, when a lot of silt gathers on the top of the lifting plate and the silt blocks the filter holes, the staff can put two fingers of both hands into the drain trough and pinch the lifting block, and then lift the lifting plate upwards. This process will make the cleaning column pass through the corresponding filter holes and push away the silt inside the filter holes. If the operation is not effective once, it can be repeated to make the lifting plate move up and down continuously. Even if the cleaning column repeatedly passes through the filter holes, the filter holes can be unblocked and cleaned. The operation is very simple and convenient, and the cleaning effect is good, saving time and effort, and it is worth promoting.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] See also Figure 1-4In the embodiment of the utility model, a prefabricated drainage ditch for community renovation construction includes a plurality of U-shaped grooves 1 that can be spliced ​​with each other, the inner side of the U-shaped groove 1 is a drainage channel 8, a lifting plate 6 is arranged in the drainage channel 8, and three groups of filter holes 7 are arranged on the lifting plate 6. The top of the drainage channel 8 is rotatably connected with a grille cover plate 2 through a plurality of hinges, and the side of the grille cover plate 2 away from the hinge is fixedly connected to the top of the U-shaped groove 1 by mounting bolts 14. Four drainage grooves 4 are opened at equal intervals on the top of the grille cover plate 2 along its length direction, and slide grooves 15 are symmetrically opened on the upper part of the inner wall on both sides of the drainage channel 8. The slide grooves 15 are arranged to pass through front and back, and the interior of the slide grooves 15 is symmetrical front and back. A sliding rod 5 is provided, and the sliding rod 5 is fixedly installed between the upper and lower side walls of the slide groove 15. The left and right sides of the lifting plate 6 extend into the corresponding slide groove 15, and the lifting plate 6 is slidably sleeved on the outside of the sliding rod 5. The three groups of filter holes 7 and the four drainage grooves 4 are staggered with each other. Three groups of cleaning columns 3 are provided at the bottom of the grille cover 2. Each group of cleaning columns 3 is respectively located between two adjacent drainage grooves 4. The number of each group of cleaning columns 3 is equal to the number of each group of filter holes 7 and corresponds one to one. Two vertical rods 13 are fixedly provided on the top of the lifting plate 6. The two vertical rods 13 are respectively located between the two adjacent groups of filter holes 7. The top of the vertical rod 13 extends to the inside of the corresponding drainage groove 4 and is connected with a lifting block 12.

[0021] A plurality of holes 10 are provided on the top of the grille cover 2, and mounting bolts 14 are inserted through the bottom wall of the holes 10. Screw holes matching the mounting bolts 14 are provided on the top of the U-shaped groove 1. Through the arrangement of the holes 10, the heads of the mounting bolts 14 are completely located in the holes 10, which will not affect the passing of pedestrians or vehicles on the top of the grille cover 2, and also protect the mounting bolts 14.

[0022] The front surface of the U-shaped groove 1 is provided with a connecting card strip 9, and the rear surface of the U-shaped groove 1 is provided with a connecting card slot 11; through the snap-fitting cooperation between the connecting card strip 9 of the rear U-shaped groove 1 and the connecting card slot 11 of the front U-shaped groove 1, the overall rapid positioning and assembly of the device is achieved, which is simple to operate and highly practical.

[0023] The horizontal height of the top surface of the lifting block 12 is lower than the horizontal height of the top surface of the grille cover 2. At this time, the design allows the lifting block 12 to be located inside the drain trough 4 when no cleaning operation is being performed to avoid damage caused by being stepped on by newcomers. When in use, the staff inserts two fingers of both hands into the drain trough 4 respectively and pinches the lifting block 12, and then lifts it up. The operation is simple and convenient. At the same time, the design of the lifting block 12 will not affect the rotation and opening and closing of the grille cover 2.

[0024] Specifically, when a lot of silt gathers on the top of the lifting plate 6 and the silt blocks the filter hole 7, the staff lifts the lifting plate 6 upwards through the lifting block 12. This process will cause the cleaning column 3 to pass through the corresponding filter hole 7 and push away the silt inside the filter hole 7. If the operation is not effective once, it can be repeated to move the lifting plate 6 up and down continuously, so that the cleaning column 3 repeatedly passes through the filter hole 7 to achieve unblocking and cleaning of the filter hole 7. The operation is very simple and convenient, with a good cleaning effect, saving time and effort, and is worthy of promotion.
