Description

Connecting structure of new and old wells with rainwater square ditches

Technical Field

The utility model belongs to the technical field of the technique of municipal drainage and specifically relates to a connection structure of new and old well of rainwater square ditch is related to.

Background

The rainwater square ditch is a drainage ditch, and the specific function is to get rid of the rainwater, and when municipal construction, whether the rainwater square ditch is built rationally and whether can carry out good drainage on every side. The rainwater square ditch mainly comprises a ditch body and a cover plate covering the ditch body. The existing rainwater square ditches are mainly divided into open ditches and blind ditches. The open ditch is not provided with a cover plate or is provided with a water-passing grate as the cover plate and is mainly used for discharging ground water which can directly flow into the open ditch to be collected and discharged. The underdrains are usually buried underground or covered with concrete covers, which are mainly used to collect rainwater drained from other pipelines and then drain the rainwater together. Because the blind ditch is arranged underground or covered by a concrete cover plate, the blind ditch cannot be conveniently checked and enclosed by workers, and therefore, a check well must be arranged.

For example, chinese patent No. CN202248218U discloses a structure for connecting an open drain with a drainage inspection well, which comprises an open drain and a drainage inspection well, wherein the open drain is connected with a connection hole formed in a wall of the drainage inspection well, a grid net for intercepting sundries in the drain is installed at the connection hole, a well cover ring beam capable of installing a support of the drainage inspection well is arranged on the upper portion of the wall of the drainage inspection well, and a drainage pipe is arranged at the bottom of the drainage inspection well. When the structure is used, the grid net arranged in the connecting hole is easy to block, and the grid net needs to be dredged by workers. When workers dredge, the grating net needs to be disassembled, and then sundries blocked in the grating net and accumulated on the other side of the grating net are removed. But in the time of the grid net dismantled and clear up, can't filter the rainwater in the rainwater side's ditch, have debris to flow into in the drainage inspection shaft this moment easily to in flowing into the drain pipe, thereby lead to the drain pipe jam of drainage inspection shaft bottom easily.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a connection structure of new and old well of rainwater side ditch when the workman clears away and blocks up grid net debris, still can play and filter the rainwater in the rainwater side ditch, is difficult for leading to the drain pipe jam of drainage inspection shaft bottom.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

Referring to fig. 2 and 3, the rainwater square groove 1 and the connecting through groove 12 are both square in cross section. Connect and to lead to fixed mounting on the inside wall of groove 12 has square fixed frame 2, and fixed frame 2 sets up along the inside wall that connects groove 12. A grid net 21 is rotatably installed in the fixed frame 2, and the cross section of the grid net 21 is equal to the cross section of the inner side surface of the fixed frame 2 in size. The upper side and the lower side of grid net 21 are all welded with vertical rotating columns 22, and two rotating columns 22 are all located at the midpoint of the upper side and the midpoint of the lower side of grid net 21. The rotary column 22 is mounted inside the fixed frame 2 and the axis of rotation of the grille net 21 is collinear with the axis of the rotary column 22. Fixing pieces 23 serving as fixing pieces are mounted on two vertical side edges of the grid net 21, the fixing pieces 23 are in a long strip shape and are rotatably mounted on the grid net 21, and the rotating axis of each fixing piece 23 is perpendicular to the grid net 21. When the fixing plate 23 rotates to the horizontal state, one end of the fixing plate 23 is located on one side of two vertical sides of the grid net 21, which are far away from each other, and the lower side of the end of the fixing plate 23 is provided with a fixing groove 24. Fixing pieces 23 are fixedly arranged on both side surfaces of the grid net 21. The fixed block 25 is fixedly mounted on two vertical side edges of the fixed frame 2, and the fixed block 25 is located on one side of the fixed frame 2 close to the center of the drainage inspection well 11. When the fixing piece 23 rotates to a horizontal state and the fixing groove 24 is located at one side of the two vertical sides of the grid net 21, which are far away from each other, the fixing piece 25 is embedded in the fixing groove 24.

Referring to fig. 2 and 3, the lower side edge of the grid net 21 is hinged with a limiting plate 3, the rotation axis of the limiting plate 3 is parallel to the lower side edge of the grid net 21, and the limiting plate 3 is hinged with one of the two side surfaces of the grid net 21. The distance between the two ends of the limiting plate 3 is less than the length of the lower side of the grating net 21. Both ends of the limiting plate 3 are welded with the bunching plates 31 perpendicular to the limiting plate 3, and the bunching plates 31 are perpendicular to the rotation axis of the limiting plate 3. When two limiting plates 3 all rotate to the horizontality, the board 31 of restrainting on the limiting plate 3 all is located the limiting plate 3 upside. Two bundling through grooves 32 are formed in the grating net 21, the limiting plate 3 can rotate to the position attached to the grating net 21, and the bundling plates 31 on the limiting plate 3 penetrate through the two bundling through grooves 32 respectively. The beam collecting plates 31 on the two limiting plates 3 are arranged in a staggered mode. The dredging lug 33 is fixedly mounted on the side face, provided with the bundling plate 31, of the limiting plate 3, the dredging lug 33 is in a quadrangular frustum pyramid shape, one end, far away from the limiting plate 3, of the dredging lug 33 is the minimum end of the quadrangular frustum pyramid, and one end, close to the limiting plate 3, of the dredging lug 33 is the maximum end of the quadrangular frustum pyramid. When the limiting plate 3 rotates to the position attached to the grid mesh 21, the dredging lug 33 penetrates through the mesh hole of the grid mesh 21.

When the filter screen is normally used, the position of the grid net 21 can be fixed through the fixing piece, so that the filter screen can normally filter. When the grid net 21 is blocked by sundries, a worker can take down the fixing piece to enable the grid net 21 to normally rotate, after the grid net 21 rotates 180 degrees, the fixing piece is reused to fix the position of the grid net 21 in the rotation of the grid net 21, and the sundries blocked on one side of the grid net 21 away from the drainage inspection well 11 can be taken out together, so that the worker can conveniently store the sundries, and then the worker can dredge the grid net 21 in the drainage inspection well 11. When the workman dredged grid net 21, grid net 21 still can filter the rainwater in rainwater square ditch 1, and difficult debris that appear flows into in the drain pipe, leads to the phenomenon of the drain pipe jam of drainage inspection shaft 11 bottom. And through being provided with limiting plate 3, can be convenient drive debris to drainage inspection shaft 11 in, the workman of being convenient for is collected and is clear away, and can be quick will block up debris such as silt of grid net 21 mesh and clear away, has improved clear speed.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
