A device for salvaging freshwater algae on the surface of a coal mining subsidence area

Abstract

This utility model relates to the field of salvage devices, specifically a device for salvaging algae from the surface of freshwater in coal mining subsidence areas. It includes a hull with a collection trough on one side and a storage trough connected to the collection trough on the upper surface of the hull. It also includes a collection unit rotatably positioned at the opening of the collection trough, which guides the algae into the trough. In this utility model, buoys enhance lateral stability and prevent capsizing. The buoys provide additional buoyancy, ensuring the device remains stable even when fully loaded with algae. The hull is driven by a small electric propeller, which compresses a spring to disengage a limiting block from its limiting slot, allowing the storage rack to be removed. When installing the storage rack, it is inserted into the storage trough. The lower edge of the storage rack presses against the angled corner of the limiting block, causing it to retract into a telescopic groove. When the limiting block aligns with the limiting slot, the spring returns to its original position, pushing the limiting block back into the limiting slot, thus securing the storage rack.

Description

Technical Field

[0001] This utility model relates to the field of salvage devices, and in particular to a device for salvaging algae from the surface of freshwater in coal mining subsidence areas. Background Technology

[0002] With the long-term mining of coal resources in my country, large areas of land have subsided due to the excavation of underground coal seams, forming numerous coal mining subsidence areas. These water bodies are mostly enclosed or semi-enclosed freshwater bodies with poor water flow, rich nitrogen and phosphorus nutrients, and abundant sunlight, making them highly susceptible to the explosive proliferation of phytoplankton such as cyanobacteria and green algae, leading to frequent algal blooms. If not treated in time, they will have a serious impact on the ecological environment, water resource utilization, and regional development. Removal devices can collect and remove floating algae from the water body, directly reducing the internal pollution load.

[0003] When harvesting algae, there is a problem that it is difficult to harvest algae from the surface of fresh water. In view of this, a device for harvesting algae from the surface of fresh water in coal mining subsidence areas is provided. Utility Model Content

[0004] The main purpose of this utility model is to provide a device for harvesting algae from the surface of freshwater in coal mining subsidence areas, so as to solve the problem in related technologies that it is difficult to harvest algae from the surface of freshwater.

[0005] To achieve the above objectives, according to one aspect of the present invention, a device for harvesting algae from the surface of freshwater in a coal mining subsidence area is provided, comprising a hull, a collection trough on one side of the hull, and a storage trough communicating with the collection trough on the upper surface of the hull, and further comprising: a collection part, which is rotatably disposed at the opening of the collection trough and guides algae into the collection trough; and a storage rack, which is inserted and installed in the storage trough, and the algae are dehydrated and removed after passing through the collection trough into the storage rack.

[0006] Furthermore, one end of the collection trough is inclined downwards, several conveying rollers are rotatably installed on the lower surface of the collection trough, and a diversion plate is fixedly installed at the opening of the collection trough, with the diversion plate inclined downwards.

[0007] Furthermore, two pontoons are symmetrically fixedly installed on both sides of the hull.

[0008] Furthermore, the collecting part includes a collecting roller, which is rotatably installed at the opening of the collecting trough. Several retrieval teeth are fixedly installed on the side wall of the collecting roller, and the retrieval teeth are made of flexible material.

[0009] Furthermore, a storage slot is provided on one side of the storage rack, the storage slot is connected to the collection slot, a number of filter slots are provided on the lower surface of the storage slot, and a drain hole is provided through the lower surface of the storage slot.

[0010] Furthermore, a handle is fixedly installed on the upper surface of the storage rack, and a limit slot is provided on one side of the storage rack.

[0011] Furthermore, a telescopic groove is provided on one side of the storage tank, and a push groove communicating with the telescopic groove is provided on the upper surface of the hull. A limit block is slidably installed in the telescopic groove. One end of the limit block has a downward inclined angle. A spring is fixedly installed on one side of the limit block, and the other end of the spring is fixedly installed on the inner side wall of the telescopic groove. A push plate is fixedly installed on the upper surface of the limit block, and the push plate passes through the push groove and is exposed to the outside.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In this invention, buoys enhance lateral stability and prevent capsizing. The buoys provide additional buoyancy, ensuring stability even when fully loaded with algae. The hull is driven by a small electric propulsion unit for autonomous navigation. The front end of the collection tank is submerged below the water surface to facilitate the interception of floating algae. The algae slide inwards due to gravity, and the conveyor rollers passively rotate with the water flow, creating a conveyor belt effect that gradually transports the algae inwards. A guide plate guides the water flow and algae smoothly into the collection tank. As the collection rollers rotate, they drive the retrieval teeth to cut into the water surface, combing the floating algae into the collection tank. In this invention, the retrieval teeth are preferably made of flexible nylon bristles. These flexible retrieval teeth undergo slight deformation upon contact with algae, gently hooking and catching the floating algae without... The filter disrupts cell structure and bends to avoid large debris, preventing stagnation. After wet algae enter the storage tank, water seeps out through the filter under gravity, while solid algae accumulate in the tank. Filtered water returns to the water body through the drain hole. The handle is located on the top surface for easy manual lifting. To remove the storage rack for algae cleaning, push the push plate to compress the spring, causing the limit block to disengage from the limit slot, allowing the storage rack to be pulled out. To install the storage rack, insert it into the storage tank. Press the angled edge of the limit block at the lower surface edge of the storage rack to retract the limit block into the telescopic groove. When the limit block aligns with the limit slot, the spring returns to its original position, pushing the limit block into the limit slot to fix the storage rack in place.
