Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

Referring to figures 1-3 for an embodiment of a drainage structure for municipal engineering construction according to the utility model,

comprises a drainage channel 1 and a filter screen 2 arranged inside the drainage channel 1; wherein, a spiral auger 3 is arranged above the surface of the filter screen 2; the screw auger 3 includes a rotation shaft 31 and screw blades 32; a sundry cavity 4 is further arranged on one side of the drainage channel 1, and the sundry cavity 4 is communicated with the drainage channel 1 through an annular hole 5; the spiral auger 3 is pushed toward the annular hole 5 in the direction of rotation and pushing.

The device is applied to municipal engineering construction projects, more dust and impurities can be generated during construction, the impurities can enter the drainage channel 1 along with water flow, then water with the impurities falls on the filter screen 2, the water flows away through the filter screen 2, and the impurities are left on the screen surface of the filter screen 2, so that the filtration of the impurities is completed;

however, the impurities stay on the surface of the filter screen 2 to block the meshes of the filter screen 2, so that water cannot flow normally, and therefore, workers are required to clean the filter screen 2 frequently, and most of the drainage channels 1 are arranged underground, so that the filter screen 2 needs to be taken out during cleaning, and drainage is stopped, and the water can be drained after the filter screen 2 is cleaned and installed, which is very time-consuming and labor-consuming.

So in order to solve the defect, the device is provided with a spiral auger 3 above the surface of the filter screen 2; the rotating shaft 31 of the spiral auger 3 works to drive the spiral blade 32 to rotate and push, so that sundries remained on the screen surface of the filter screen 2 are fed away; keep the mesh of the filter screen 2 unobstructed, realize draining while filtering, clear up the filter screen 2 at the same time; this saves time in cleaning the filter screen 2.

The hole wall of the annular hole 5 is provided with a connecting rod 6, a mounting sleeve 7 is arranged in the middle of the connecting rod 6, and the end part of the rotating shaft 31 is arranged in the mounting sleeve 7 through a bearing.

The connecting rod 6 functions to provide the mounting sleeve 7, and the mounting sleeve 7 functions to provide the position of the rotation shaft 31 and enable the rotation shaft 31 to rotate normally.

The filter screen 2 is a U-shaped plate with an arc bottom surface; and the filter screen 2 is obliquely arranged in the drainage channel 1.

The filter screen 2 is shaped in such a way that sundries can be concentrated in the middle position of the U-shaped plate when the filter screen is convenient to filter, and the spiral auger 3 is used for pushing the sundries away.

The drainage channel 1 is also connected with a first overflow channel 8; the drainage channel 1 is composed of a vertical channel 11 and a horizontal channel 12 which are communicated, the first overflow channel 8 is obliquely arranged, one end of the first overflow channel is communicated with the vertical channel 11, and the other end of the first overflow channel is communicated with the horizontal channel 12.

The drainage channel 1 in the device is divided into a vertical channel 11 and a horizontal channel 12, normal water flow can fall from the vertical channel 11 and enter the horizontal channel 12 after being filtered by the filter screen 2; however, if the water flows too much, the carried sundries are not cleaned out by the spiral auger 3, the water level rises, the first overflow path 8 is arranged to ensure that the water level cannot overflow from the vertical path 11, and the rising water level enters the horizontal path 12 from the first overflow path 8 after reaching the position of the first overflow path 8 to help drainage.

The sundry cavity 4 is separated from the vertical channel 11 by a partition plate, and the annular hole 5 is arranged on the partition plate in a penetrating way; and a second spillway 9 is also provided on the partition below the annular hole 5.

In the device, the spiral auger 3 pushes sundries into the sundry cavity 4 from the filter screen 2, but the sundries carry a large amount of water, the water occupies the space of the sundry cavity when entering the sundry cavity 4, and the redundant water can be led into the drainage channel by the second overflow channel 9.

A filter screen 10 is arranged in each of the first overflow 8 and the second overflow 9.

The driving device of the spiral auger 3 in the device adopts a motor and is in key connection with the rotating shaft 31 through a bevel gear component, the specific motor can be arranged according to the position, depth and direction of the drainage channel 1, and the motor of the device is arranged in the space between the vertical channel and the first overflow channel.

The function of the screen 10 is to prevent impurities from being discharged when the water passes through the first spillway 8 and the second spillway 9.

The above embodiments are merely illustrative embodiments of the present utility model, but the technical features of the present utility model are not limited thereto, and any changes or modifications made by those skilled in the art within the scope of the present utility model are included in the scope of the present utility model.
