Embodiment 1

[0017] Such as figure 1 As shown, this embodiment includes: isolation curtain 1, shape memory alloy spring 2, bias spring 3, pull cord 4, fixed ring 5, frame 6, rotating shaft 7, buckle 8, baffle plate 9, floating body 10, pull ring 11. Steel wire 12, floating body stay rope 13 and fixture 14, wherein: the rotating shaft 7 is fixed on the isolation curtain 1, and the two ends of the rotating shaft 7 are movable on the frame 6, and the two ends of the isolation curtain 1 are connected with the two stay ropes respectively. 4 are fixedly connected, one end of a pull rope 4 is fixedly connected with the frame 6 and the shape memory alloy spring 2, and one end of the other pull rope 4 is fixedly connected with the frame 6 and the bias spring 3, and the shape memory alloy spring 2 and the bias spring 3 All are fixed on the frame 6, and the floating body 10 is fixed on the bottom of the frame 6.

[0018] The buckle 8 is arranged at the end of the rotating shaft 7 to prevent the move...

Embodiment 2

[0027] In this embodiment, the size of the isolation curtain 1 is designed to be 5m × 0.2m, the thickness is 0.003m, and the material selection density of the isolation curtain 1 is 50kg / m according to the area that needs temperature control and algae killing in the water area. 3 The plastics, the one side of separation curtain 1 facing the sun is coated with reflective layer, and the reflectivity is 110%, and 25 separation curtains 1 are made altogether. The shape-memory alloy spring 2 of the present embodiment is made of nickel-titanium alloy, coated with an anti-corrosion layer, and its phase transition temperature is 25 degrees. The heat-shrinkable shape-memory alloy spring can provide a pulling force of 50N, and its length in a fully contracted state is 10cm; choose bias spring 3 to use carbon spring steel wire, which can provide a pulling force of 50N when it shrinks, and its length is 10cm when it is fully contracted; make frame 6, choose light aluminum alloy material, c...

Abstract

The invention discloses an automatic curtain temperature control and algae removal device for a shallow water body, and relates to the technical field of water treatment. The device comprises a plurality of isolating curtains, a rotating shaft, a frame, a floating body, a shape memory alloy spring, a bias spring, pull ropes and a fixture, wherein the rotating shaft is fixed to the isolating curtain and the two ends of the rotating shaft are movably arranged in the frame; the two ends of each isolating curtain are fixedly connected with the two pull ropes respectively; one end of one pull ropeis fixedly connected with the frame and the shape memory alloy spring, and one end of the other pull rope is fixedly connected with the frame and the bias spring; both the shape memory alloy spring and the bias spring are fixed to the frame; the floating body is fixed to the bottom of the frame; and the floating body is connected with the fixture at the bottom of the water body or at the shore. The device of the invention has simple structure, convenient use, low implementation cost and easy disassembly and removes the external cause for the growth of blue-green algae by a physical method without changing the ecological environment in the water bottom or causing new water quality problem.

Description

technical field [0001] The invention relates to a device in the technical field of water treatment, in particular to an automatic curtain-controlled temperature algae killing device for shallow water bodies. Background technique [0002] Under the action of continuous high temperature, when the fluidity of shallow lakes, reservoirs, etc. is low and the nitrogen and phosphorus content of the water body reaches a certain ratio, the water body temperature is relatively easy to reach the rapid growth temperature of cyanobacteria at 25-32 °C. In addition to environmental dredging methods, most of the methods to eliminate cyanobacteria are biological or chemical. Such methods are often ineffective for large-scale water bodies, especially for water source reservoirs, and may even bring new water quality problems. Therefore, it is necessary to develop new methods to prevent the large-scale outbreak of cyanobacteria in shallow lakes, reservoirs and other water bodies in my country. ...
