Description

Technical Field

[0001] The invention relates to the technical field of reservoir evaporation prevention, and in particular to a telescopic floating reservoir evaporation prevention device and a use method thereof. Background Art

[0002] Reservoirs are important water conservancy projects for storing water and regulating water flow. However, during the operation of reservoirs, evaporation is one of the important factors causing water waste. In order to reduce the losses caused by reservoir evaporation, effective anti-evaporation technology needs to be implemented. The design background of reservoir anti-evaporation technology mainly stems from the demand for rational use of water resources and the emphasis on ecological environmental protection.

[0003] The current reservoir evaporation prevention technologies mainly include mulching, ecological planting, plant transpiration, bubble evaporation prevention and other methods. Mulching film technology is a commonly used evaporation prevention measure that reduces water surface evaporation by laying a film on the water surface. Ecological planting uses wetland vegetation to cover the water surface to reduce evaporation and improve water quality. Plant transpiration reduces water surface evaporation by planting vegetation around the reservoir and using plants to absorb water and release it into the air through transpiration. Bubble evaporation prevention technology forms a bubble covering layer by spraying bubbles on the water surface, reducing direct water surface exposure and slowing down the evaporation rate.

[0004] However, the existing reservoir evaporation prevention technology still has some problems and shortcomings. First of all, although the covering membrane technology effectively reduces evaporation, the membrane material cost is high and installation and maintenance are difficult. At the same time, the environmental friendliness of the membrane material is also worthy of attention. Ecological planting and plant transpiration require a lot of time and resources for maintenance and management, and are greatly affected by factors such as season and climate. Bubble anti-evaporation technology reduces evaporation to a certain extent, but it may have a certain impact on the ecological environment of the water body, which requires further research and evaluation.

[0005] In summary, although reservoir evaporation prevention technology can reduce the loss of water resources to a certain extent, the existing technology still has some limitations and problems. The existing anti-evaporation equipment has a large reminder, which is not conducive to rapid transportation and assembly. At the same time, the contact area with the water body is large, which is not conducive to fully ensuring the quality of the water body, and the service life is short, so it needs to be improved.

The telescopic floating reservoir anti-evaporation device according to claim 1, characterized in that: The buoy assembly (4) is composed of four buoy bodies (402), and the four buoy bodies (402) form a rectangular structure. The four corners of the buoy body (402) are each provided with an arc-shaped notch (401), and a slide groove (408) is provided in the arc-shaped notch (401). A ring (404) is slidably installed in the slide groove (408), and a screw (405) is commonly penetrated through the four rings (404) located in the middle. Two pressure rings (406) are provided on the rod (405), and the pressure rings (406) are in conflict with the four buoy bodies (402). A threaded sleeve (403) is fixed to the upper end of the screw rod (405), and a nut (407) is threadedly sleeved on the lower end of the screw rod (405). Two of the threaded sleeves (403) are connected to the left end rod component (1), and the other two threaded sleeves (403) are connected to the right end rod component (7).

10. A method for using a telescopic floating reservoir anti-evaporation device, applicable to the telescopic floating reservoir anti-evaporation device of claims 1 to 9 above, characterized in that: The following steps are involved: S1. Assembling the buoys: the four buoy bodies (402) form a rectangle, and the circular rings (404) on the four buoy bodies (402) are arranged to overlap from top to bottom, and the screw (405) passes through the four circular rings (404) and the pressure ring (406), and under the action of the nut (407), the screw (405) and the pressure ring (406) squeeze the four buoy bodies (402) from top to bottom, so as to complete the assembly of the buoy assembly (4), and make the four buoy assemblies (4) a group, and the four buoy assemblies (4) are arranged in a rectangular shape and distributed at the four corners of the rectangle; S2, rod connection: the four buoy assemblies (4) are arranged in groups of two, and the two groups of buoy assemblies (4) correspond to the left end rod assembly (1) and the right end rod assembly (7) respectively, and are connected to the threaded sleeve (403) on the corresponding buoy assembly (4) through the first connecting bolt (104) and the second bolt member (703), and the left end rod assembly (1) and the right end rod assembly (7) are arranged opposite to each other, so that the connecting member (2) and the anchor assembly (3) are located between the left end rod assembly (1) and the right end rod assembly (7); S3, assembling the light shielding component: the two plug-in rods (701) are respectively plugged into the two sleeves in the left end rod component (1), so that the positioning rod (704) is inserted into the corresponding positioning hole (103); S4, adjusting the shading area: installing the round tube (801) on the right end rod assembly (7), pulling the shading cloth (802) and the connecting piece (2) to connect, adjusting the unfolded area of ​​the shading cloth (802) as required, and adjusting the positioning rod (704) to be inserted into the corresponding positioning hole (103); S5: water entry operation: the assembled square evaporation device is transported into the reservoir, the buoy assembly (4) contacts the water surface, and the pull rope (301) and the anchor body (302) are controlled to descend and effectively fixed, and the shading cloth (802) can effectively block sunlight and condensed water vapor.
