Description

River channel blocking and dirt removing device

Technical Field

The utility model belongs to the technical field of river trash removal technique and specifically relates to a river course blocks trash removal device.

Background

For the river channels provided with hydraulic structures such as water gates, the trash rack is usually arranged at the inlet of the river channel to prevent the dirt (such as straws, plastic articles, dead livestock, woven bags, trees and the like) in the water flow from silting the structures and influencing the safe operation of the engineering. The existing trash rack is generally composed of grid bars, main beams and a frame, is large in area and small in structural rigidity, is easy to deform or even damage under the action of river water flow, and is easy to block grid holes after dirt is intercepted, if the trash rack is not cleaned in time, the flow area of the trash rack is reduced, and the flow capacity of river hydraulic buildings can be reduced. Therefore, a trash remover is arranged near the trash rack. However, as the flood discharge time of the river channel is short, the trash cleaning machine is in an idle state for about 80% of the year, good maintenance is difficult to achieve in an open air state, the trash cleaning machine often cannot work normally when a flood season comes, and the emergency trash cleaning work still only depends on manual treatment. The danger of manual sewage disposal is large, and flood discharge safety is affected when large-sized sewage which is not easy to be removed in time is encountered.

Furthermore, the included angle between the connecting line of the first fixing pile and the second fixing pile and the water flow direction is 45 degrees, so that dirt can smoothly enter the dirt collecting pool.

Furthermore, the dirty pond of collection is the arc pond that uses the second spud pile as the centre of a circle, makes the filth can get into the dirty pond of collection as far as possible.

Further, the radius of the sewage collecting pool is 1-2m.

Further, still be provided with a plurality of reinforced piles between first spud pile and the second spud pile, reinforced pile is located the river course, and sets up with first spud pile and second spud pile collineation.

The utility model provides a river course blocks device of decontaminating, simple structure, easily installation is convenient for maintain, can the interior floater of dynamic interception river course to utilize river course rivers impulsive force to wash large-scale filth to the dirty pond of collection, conveniently in time clear up and do not influence flood discharge safety. The utility model discloses be particularly suitable for the river course of broad, need not to set up trash cleaning machine, reduced equipment investment and later maintenance expense, only need artifical clearance bank edge collect dirty interior filth can, reduced the operation danger by a wide margin.

Detailed Description

The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific working procedures are given, but the scope of the present invention is not limited to the following embodiments.

Example 1:

as shown in figures 1 and 2, the river blocking and dirt removing device of the utility model is composed of a first fixed pile 1, a second fixed pile 2, a dirt blocking net 3 and a dirt collecting pool 4.

The first fixing pile 1 and the second fixing pile 2 are C30 concrete cast-in-place piles which are respectively arranged on the river banks on two sides, and the first fixing pile 1 is located at the downstream of the second fixing pile 2. Typically, the line connecting the first and second spuds 1 and 2 is at an angle of 45 ° to the direction of water flow. In order to improve the structural stability, the parts of the first fixing piles 1 and the second fixing piles 2 buried below the horizontal line of the river bank are 1/2 of the length of the pile body, and the tops of the first fixing piles and the second fixing piles are 1 meter above the highest water level line.

Two ends of the trash rack 3 are respectively connected with the first fixing pile 1 and the second fixing pile 2. Specifically, both ends of the trash rack 3 are lantern rings 31, which are respectively sleeved on the first fixing pile 1 and the second fixing pile 2 and can slide up and down. An upper cable 32 and a lower cable 33 which are arranged in parallel are arranged between the two lantern rings 31, the upper cable 32 and the lower cable 33 are both steel wire ropes, the distance between the upper cable 32 and the lower cable 33 is 0.5m, and a plurality of floating blocks 34 are arranged between the upper cable and the lower cable at intervals to serve as floating blocking pieces. The blocking net 3 takes the lantern ring 31, the upper pull rope 32 and the lower pull rope 33 as a supporting framework, and floats up and down along the fixing pile along with the change of the water level under the action of the floating wood 34, meanwhile, the floating wood 34 arranged at intervals can also block dirt floating on the water surface, and further, the dirt is flushed out along the blocking net 3 to the river bank on one side of the second fixing pile 2 under the action of water flow.

In order to collect the dirt conveniently, a dirt collecting pool 4 is dug at the dirt rushing-out position. The sewage collecting tank 4 is an arc-shaped tank which takes the second fixing pile 2 as the circle center and has the radius of 1-2m.

Because the utility model discloses can realize automatic collection dirty, the filth of being intercepted is concentrated and is stored in the dirty pond 4 of collection, consequently, does not influence the flow area of trash rack 3, does not influence the river course and moves flood.

Example 2:

in order to keep the trash rack 3 in a straight line state as much as possible and ensure that the trash smoothly flows to the trash collecting tank 4, a plurality of reinforcing piles 5 (1 reinforcing pile 5 in fig. 3 can be increased or decreased according to actual conditions) are further installed in the river channel between the first fixing pile 1 and the second fixing pile 2, the reinforcing piles 5 are embedded in the same manner as the first fixing pile 1 and the second fixing pile 2, and the three reinforcing piles are arranged in a collinear manner. The remaining components and mounting are the same as in example 1.

It should be noted that in the description of the present invention, terms of orientation or positional relationship such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
