Description

A river and lake water ecological purification device

Technical Field

The present invention belongs to the technical field of river and lake water purification, and more specifically, relates to an ecological purification device for river and lake water.

Background technique

With the development of cities and towns and the expansion of industrial scale, the water pollution of my country's rivers and lakes is becoming more and more serious. There is a lot of garbage floating on the surface of rivers and lakes, of which plastic garbage accounts for a large proportion. This has caused great pollution to rivers and lakes, not only affecting the ecological environment of rivers and lakes, but also affecting the organisms in rivers and lakes, thus affecting the overall ecology of rivers and lakes.

In order to solve the impact of floating garbage in rivers and lakes, it is generally cleaned manually, but the cleaning frequency is high and the cleaning is inconvenient, and the risk factor is high. Therefore, many rivers and lakes currently use garbage collectors to clean up garbage. As long as the garbage collector is placed in the water, the floating garbage in the surrounding area can be collected. It is mainly through the connected water pump that a negative pressure is generated in the collector to form a water level difference. The surrounding floating garbage is continuously sucked into the collector along with the water. The garbage will be concentrated in the inner tank of the collector, and the garbage that enters the collector will be pumped out by the water pump. This cycle can be used in this way, and the inner tank in the collector can be taken out after a period of time.

However, when the garbage collector collects floating garbage on the water surface, some large drifting garbage such as plastic bottles on the water surface will also enter the garbage collector with the water flow, which will cause the inner tank of the collector to be filled up quickly, resulting in an increase in the number of manual cleaning of the inner tank, which is time-consuming and labor-intensive; and some large garbage will block or get stuck at the garbage entrance of the collector, thereby affecting the collection of other garbage and affecting the use effect of the collector.

Therefore, it is necessary to provide a river and lake water ecological purification device to solve the above technical problems.

The plurality of interference mechanisms 3 are located around the garbage collector 1 and are used to prevent large garbage from entering the garbage collector 1; a transmission mechanism 4, which is arranged on the support plate 2 and is used to drive the plurality of interference mechanisms 3 to rotate synchronously; a collection box 5, which is connected to the support plate 2 and is used to collect large garbage on the water surface. The collection box 5 is provided with a conveying mechanism 6 for allowing large garbage on the water surface to enter the collection box 5.

When in use, the device can be connected to the collection box 5 through an external device, and can drive the collection box 5 and the support plate 2 to be lifted in the vertical direction and rotated in the horizontal direction, so as to facilitate the installation and subsequent cleaning of the device. The support plate 2 of the device is placed above the water surface garbage collector 1, so that the multiple interference mechanisms 3 are located around the collection port of the garbage collector 1, and the bottom of the interference mechanism 3 is at a distance above the water surface and does not touch the water surface. After that, the equipment can be started, and the conveying mechanism 6 and the transmission mechanism 4 can be started. The transmission mechanism 4 will drive multiple interference mechanisms 3 to rotate simultaneously. When the garbage collector 1 is in use, the smaller floating garbage around it will enter the inner tank of the garbage collector 1 with the water flow, while the larger floating garbage such as plastic bottles will be blocked by the interference mechanism 3, making it impossible for them to enter the inner tank of the garbage collector 1, and the rotation of the interference mechanism 3 will cause large garbage such as plastic bottles to move around the garbage collector 1. When it moves to the position of the conveying mechanism 6, the large floating garbage such as plastic bottles on the water surface can be driven into the collection box 5 through the conveying mechanism 6, that is, the large floating garbage such as plastic bottles is collected by the collection box 5, thereby achieving the ecological purification effect of rivers and lakes. Thereby, some large garbage such as plastic bottles on the water surface can be prevented from entering the garbage collector 1, that is, the garbage collector 1 can be prevented from being filled up quickly, the frequency of manual cleaning of the garbage collector 1 can be greatly reduced, a large amount of manpower can be saved, and the working time of the garbage collector 1 can be greatly extended; and it can also avoid the situation that large garbage such as plastic bottles will be blocked or stuck at the entrance of the garbage collector 1, which greatly prevents the collection of other small floating garbage from being affected, greatly improves the collection and cleaning effect of garbage on the surface of rivers and lakes, effectively improves the water quality of rivers and lakes, and has a good ecological purification effect.
