Description

Hydraulic guided urban river garbage collection device

technical field

The utility model relates to the technical field of water conservancy engineering, in particular to a hydraulic guide type urban river garbage collection device, which is used for urban river garbage collection.

Background technique

In addition to the function of flood discharge or sewage discharge, the rivers flowing through the city should also have the functions of landscape and ecological services. After rain, a large amount of garbage is often washed into the river, such as plastic bags, beverage bottles, branches and leaves, and a small number of animal carcasses. Usually, some garbage enters the river for various reasons, and the resulting floating garbage will greatly affect the water quality and urban landscape. For these floating garbage, the commonly used cleaning methods mainly include the following three: manual salvage, cleaning by cleaning boats, and setting up trash racks to intercept and then conduct centralized cleaning.

The method of cleaning and drifting depends on the characteristics of the specific river and water body, as well as the location and the discharge of garbage. At present, many areas still use manual salvage methods, but this method is labor-intensive, the working environment is harsh, and the efficiency is low. Secondly, it is to take the trash rack to intercept the garbage, and then use the method of manual salvage to clean it up. In this way, a large amount of garbage is intercepted on the surface of the river and cannot be cleaned in time, which affects the urban landscape and brings hidden dangers to flood discharge.

The surface garbage automatic salvage ship is dedicated to the cleaning of solid garbage in small and medium-sized lakes and rivers. Due to different waters, different types of garbage and different recycling amounts, various types of surface garbage collection vessels have been formed, such as ZS-800 surface drifting vessels, 16.5-meter surface garbage collection vessels, and so on. However, such large-scale ship machinery is mainly used for the collection of large-scale and large-area waters. Its structure is complex, bulky, expensive, and requires professional operation, so it cannot be widely used in urban rivers and scenic waters. Garbage collection job.

As shown in Figure 3, the downstream part of the flushing pipeline is connected to the water inlet 4 by twisting twice, the water outlet 3 is perpendicular to the shore, the nozzle is close to the downstream water surface of the water retaining structure, and a buoyancy device 5 is provided below the water outlet 3 , and a telescopic section 2 is set above. To ensure that the nozzle elevation changes with the downstream water level. When the water flows from the upstream to the downstream through the flushing pipe, the potential energy is converted into kinetic energy, which impacts the floating garbage on the river surface and makes it flow to the stagnant area on the opposite bank along the water flow to achieve the effect of collection.

As shown in Figures 4 and 5, the collection device includes a garbage collection box 7, a guide rail 10 and a reel 8. The garbage collection box 7 is placed on one side of the river surface, part of the box body is located in the water, and the guide rail 10 extends from the river bank to the water surface , the garbage collection box 7 is pulled up and down along the guide rail 10 by the traction rope 6 of the reel wheel 8 . The garbage collection box 7 is in the shape of a quadrangular prism, the upper and lower bottom surfaces are solid surfaces, and the rest are mesh surfaces. The upstream side has an opening for garbage entry, and the side facing the guide rail 10 can be opened upward.

As shown in Figure 6, the inclined riverbed 1 is a part of the riverbed downstream of the water retaining structure and close to the building, and its vertical river bank cross-section is a right-angled triangle, and the side where the collecting device is located is lower than the side where the flushing pipe is located.

The collection method of the hydraulic guided urban river garbage collection device, the upstream water flow of the water retaining structure passes through the diversion groove 1 and is divided into multiple inclined water flows to divert the floating garbage, and the water drawn from the flushing pipeline is supplied from the river bank side. The impact pushes the rubbish towards the collection device on the opposite bank. When the garbage in the garbage collection box 7 of the collecting device is collected to a certain level, the reel wheel 8 drives the garbage collection box to rise to the shore along the guide rail 10 .

Further analysis, as shown in Figure 1, when the upstream floating garbage falls to the downstream through the water retaining structure, at this time, due to the rapid impact of water flow, a vortex area is formed in the front part of the water retaining structure, and the floating garbage rotates around here. The surface of the water-retaining building itself is built with diversion grooves 1 to separate the upstream water flow into multiple sloping water flows to impact the floating garbage, plus the impact of the water flow from the water outlet 3 of the flushing pipe, so that the garbage on the river surface is collected from the garbage. The box 7 is gathered on one side. When the garbage is collected to a certain extent, the garbage collection box 7 is driven to the shore by the reel 8, and the cleaning personnel take out the garbage and put it back to its original position. The above is a complete process of garbage cleaning in urban rivers. When the flood season comes, it is only necessary to increase the number of collection processes to quickly collect floating garbage.
