Description

Underwater silt removing device

Technical Field

The invention relates to a dredging device, in particular to an underwater silt removing device.

Background

River dredging generally refers to river treatment, and belongs to hydraulic engineering. The silt deposited on the river bottom is blown and stirred into turbid water by mechanical equipment and flows away along with the river water, so that the dredging effect is achieved. At present, the common dredging equipment can be a cutter suction type sludge dredger or a bucket type sludge dredger or mud-water separation equipment if the river channel is shallower and the sludge is less. If the river channel is wider, a pontoon, an excavator, a loader, a dump truck, a traffic truck, a backhoe excavator, a sludge solidification device (a sludge filter press), a wetland excavator, a solid-liquid separator and the like are needed to be adopted in the large engineering. River channel siltation increasingly affects the normal play of various functions such as flood control, drainage, irrigation, water supply, navigation and the like. However, in real work, for urban rivers, there are often a lot of water grass and the river flow rate is low, so simple blowing is not enough to remove the sludge. In addition, the river is shallow and the surface width is narrow, so that the river is not suitable for large-scale mechanical operation.

Detailed Description

The present invention will be described in detail below with reference to the drawings and detailed description to enable those skilled in the art to better understand the technical scheme of the present invention.

Various aspects and features of the present invention are described herein with reference to the accompanying drawings.

These and other characteristics of the invention will become apparent from the following description of a preferred form of embodiment, given as a non-limiting example, with reference to the accompanying drawings.

It is also to be understood that, although the invention has been described with reference to some specific examples, a person skilled in the art will certainly be able to achieve many other equivalent forms of the invention, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.

The above and other aspects, features and advantages of the present invention will become more apparent in light of the following detailed description when taken in conjunction with the accompanying drawings.

As shown in fig. 1 to 4, the underwater silt removing apparatus of the present invention comprises a floating hull 11, the floating hull 11 is driven by a motor, the output shaft of the motor is connected to a driving shaft through a speed reducer, and both ends of the driving shaft are respectively provided with a first driving wheel 12 and a second driving wheel 13 for walking, wherein, the structure of the floating hull 11 and the power assembly part thereof, such as the motor and the speed reducer or the driving shaft part, does not belong to the present invention, and a person skilled in the art can completely select a proper hull structure to perform the dredging according to the need. The design part of the ship body is independent of dredging efficiency, and the ship body only serves as a water carrier and provides power output of a dredging mechanism. Therefore, the present invention is not specifically illustrated and described herein. However, it is essential to the invention that a silt removing drum 19 is also provided at the bottom of the floating hull 11, the rotation shaft of the silt removing drum 19 being drivingly connected to the drive shaft. In the invention, the sludge cleaning roller 19 is used for physically acting on river bottom sludge, and is similar to a plow harrow principle, so that the river bottom sludge is dredged and scattered, and sediment sludge is conveniently taken away by river flow.

In some modifications, as shown in fig. 5 to 8, the sludge cleaning roller 19 includes a plurality of roller units 191 coaxially connected to each other, each roller unit 191 includes a roller body 1912 and end caps 1911 disposed at both ends of the roller body 1912 for flange connection to each other, and a plurality of cutting ridges 1914 for cutting sludge or aquatic weed are formed on the outer circumferential surface of the roller body 1912. During the traveling process of the floating hull 11, the power assembly of the floating hull 11 drives the first driving wheel 12 and the second driving wheel 13, and simultaneously drives the sludge cleaning roller 19, and at the moment, the cutting ridge 1914 can cut the sludge at the river bottom. In the process, the aquatic weeds growing on the river bottom sludge can be cut together, so that the sludge can be removed better.

Since the sediment of the river bottom sludge may be hardened to be a lump, in some modifications, as shown in fig. 5 and 6, it is preferable that the drum unit 191 is constructed with a hollow cavity in which a spiral vane 1917 for scattering the sludge is provided, along a tangential direction of an outer circumferential surface thereof, with a sludge inlet 1913 and a sludge outlet 1915, respectively. In this way, during the cleaning process, the roller unit 191 can suck the sludge and the aquatic weed into the hollow cavity of the roller unit 191 after being cut in a row, and the sludge is further dispersed by the spiral fan blades 1917 and then discharged, which is more beneficial to the sludge being taken away by the flowing water.

In order to facilitate the entry of sludge into the drum unit, in other modifications, as shown in fig. 5 and 6, the sludge inlet 1913 and the sludge outlet 1915 protrude from the outer circumferential surface of the drum unit 191, and a plurality of the cutting ridges 1914 are inclined to form a guide passage for facilitating the entry of sludge into the hollow chamber. Of course, in order to prevent the aquatic weed from entering the hollow cavity and causing the entanglement, a plurality of baffles for preventing the aquatic weed from entering are provided on the sludge inlet 1913 and/or the sludge outlet 1915.

As further shown in fig. 7 and 8, in some embodiments, a middle frame 1916 is disposed between two end covers 1911 of the roller unit 191, the middle frame 1916 is disposed near the sludge inlet 1913 or the sludge outlet 1915, and is configured as a first guide cavity 19131 and a second guide cavity 19151, respectively, and the spiral fan blades 1917 are disposed at a middle position of the middle frame 1916.

As a still further improvement, the forward end of the traveling direction of the floating hull 11 is provided with a float collecting mechanism 17 extending to the water surface, which is configured to guide the water surface float to the end of the traveling direction of the floating hull 11. The float collecting mechanism 17 is a stop lever hinged to both sides of the end of the floating hull 11 through a column 16. The two stop rods are arranged at an included angle, and the angle can be adjusted according to the river surface width. The rear end of the floating hull 11 in the traveling direction is provided with a housing portion 14, and a conveying mechanism 15 for conveying the floating objects to the housing portion is provided between the housing portion and the floating object collecting mechanism 17. The transmission mechanism 15 includes a conveyor belt, which is in transmission connection with the first driving wheel 12 and the second driving wheel 13, specifically, a driving sprocket 121 is disposed on a driving shaft of the first driving wheel 12 and the second driving wheel 13, a driven sprocket 122 is disposed on a rotating shaft of an end of the conveyor belt, and a transmission chain 123 is disposed between the driving sprocket 121 and the driven sprocket 122.

Further, in order to prevent the floats on the conveyor belt from being re-scraped into the river by the wind, a ceiling 18 may be provided on the conveyor belt. And the floating hull 11 is positioned at one side of the conveyor close to the bow, and is provided with a first barrier 111 and a second barrier 112 for preventing floating objects from sliding off.

The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this invention will occur to those skilled in the art, and are intended to be within the spirit and scope of the invention.
