Description

Technical Field

[0001] The invention relates to the technical field of water surface evaporation prevention, in particular to an automatically water-filled wheeled water surface evaporation suppression device. Background Art

[0002] Arid plain reservoirs are affected by the specific natural environment, with large seasonal changes in storage capacity and large annual ineffective evaporation losses. Under the influence of long sunshine, high radiation, large temperature difference and strong wind, the temperature difference between day and night in the water body changes greatly, and the resulting water vapor pressure difference is the main reason for the ineffective evaporation losses of large water bodies in arid plains. Solving the problem of water evaporation losses caused by temperature difference, wind speed and radiation will greatly improve water utilization.

[0003] At present, the methods that can be used as means to inhibit ineffective evaporation of water bodies mainly include: physical covering, chemical reagents, biological covering and physical shielding. The first three mainly start from reducing the influence of radiation and temperature, and the latter mainly starts from reducing the influence of wind speed, all of which have significant effects; among them, physical covering has become the most commonly used inhibition method because of its simple operation. The physical covering method is friendly to water quality and the environment and has obvious effects, so different coverings have been derived, including floats, benzene boards and photovoltaic panels. Among the above-mentioned coverings, floats are widely used in large reservoirs at home and abroad because of their simple structure, low cost and easy laying method. However, the disadvantages of floats cannot be ignored, such as easy rolling under wind and waves, thereby exposing the wet surface to reduce the evaporation inhibition efficiency, and low utilization efficiency of the covering surface.

[0004] In view of the above problems, the present invention provides a wheeled water surface evaporation suppression device which is automatically filled with water. Summary of the invention

[0005] The purpose of the present invention is to provide an automatically water-filled wheeled water surface evaporation suppression device to solve the problems raised in the above background technology. The device can significantly suppress water surface evaporation and reduce ineffective evaporation losses in plain reservoirs and large water bodies.

[0006] To achieve the above-mentioned purpose, the present invention provides an automatically water-filled wheeled water surface evaporation suppression device, the wheeled water surface evaporation suppression device is an integrated structure, including an external cavity, a central water-filled cavity, and a groove sandwich formed therebetween;

[0007] The external cavity includes three layers of symmetrically arranged frustums of different diameters;

[0008] The central water-filled cavity includes a central truncated cone and an upper micro-curved surface and a lower micro-curved surface connected to the upper and lower sides of the central truncated cone, a water inlet hole is opened at the center of the lower micro-curved surface, and an exhaust hole is opened at the center of the upper micro-curved surface;

[0009] A reinforcing belt is arranged at the bottom of the groove interlayer, and drainage holes are symmetrically arranged at the diameter on both sides of the groove interlayer.

[0010] Preferably, the three layers of cones with different diameters are, from top to bottom, the first cone, the second cone and the third cone; the diameter of the lower base surface of the third cone is 100-600mm, the angle between the side slope and the horizontal plane is greater than 85°, the upper base surfaces of the second cone and the third cone are connected by an arc transition, the center angle of the arc is less than 90°, the arc is extended to connect the first cone and the second cone, and the diameter of the first cone is 70-90% of the diameter of the third cone.

[0011] Preferably, the thickness of the external cavity is 2-5 mm, and the vertical height of the external cavity is 15%-35% of the diameter of the third cone.

[0012] Preferably, the central cone is connected to the upper micro-curved surface and the lower micro-curved surface via a vertex arc, and the central angle of the vertex arc is less than 90°.

[0013] Preferably, the diameter of the central cone is 20-95% of the diameter of the third cone, and the vertical height of the central water-filled cavity is 100-150% of the vertical height of the central cone.

[0014] Preferably, the diameters of the water inlet and the exhaust holes are 5-10 mm.

[0015] Preferably, the thickness of the groove interlayer is 5-10 mm, and the diameter of the drainage hole is 3-5 mm.

[0016] Preferably, the minimum diameter ratio of the outer cavity, the groove interlayer and the central water-filled cavity is 2:1:7 or 7:1:2.

[0017] Preferably, the wheeled water surface steam suppression device is produced by an integrated blow molding process to form an integrated structure.

[0018] When preparing the automatic water-filling wheeled water surface evaporation suppression device of the present invention, different diameters need to be selected for different water areas, which can effectively increase the coverage rate of the water surface and enhance the evaporation suppression effect; when fixing the groove ratio designed only for weight gain and reflux, the buoyancy can be enhanced by enlarging the external cavity and reducing the proportion of the central water-filled cavity, and vice versa, so as to select the most suitable size according to different environments and enhance the evaporation suppression effect.

[0019] The arc treatment of the top corners, the side surfaces of the truncated cone, and the limitation of the angles between the central angle and the bottom angle of the side surfaces of the truncated cone and the horizontal plane involved in the present invention have the following purposes: first, to prevent top corner collisions, reduce the force on the collision contact surface, increase the anti-collision ability and enhance durability; second, to ensure the reflux effect after splashing of rainwater and waves, and to cooperate with hydrophobic materials and drainage holes to give full play to the weight gain effect while reducing the impact on the evaporation suppression effect; third, the center is high, and the height gradually and smoothly decreases on both sides, which can improve the resilience of the superimposed materials in unexpected situations.

[0020] Therefore, the present invention adopts the above-mentioned automatic water-filling wheeled water surface evaporation suppression device, which has the following beneficial effects:

[0021] (1) The present invention can realize automatic water filling and weight increase by setting the upper exhaust hole and the lower water inlet hole, thereby enhancing stability. In wind and waves, the side drainage holes of the groove interlayer can also be set to realize water accumulation and weight increase of the groove interlayer, further increasing stability and ensuring the overall coherence and integrity of the covering system;

[0022] (2) The present invention adopts a wheel-shaped design in which the center is filled with water and the external cavity provides buoyancy, thereby ensuring a stable center of gravity and uniform buoyancy, which plays a vital role in the stability of the overall structure. Compared with the spherical design, the wheel-shaped design compresses the vertical space and increases the horizontal effective coverage area;

[0023] (3) In addition to the automatic water filling design of the upper and lower air vents and water inlet holes, the drainage holes in the grooves are combined with the overall smooth design and hydrophobic materials to play the role of returning rainwater, water accumulated under wind and waves, and dew under the influence of temperature differences;

[0024] (4) The wheeled design adopted by the present invention compresses the vertical space, facilitates transportation and lowers the center of gravity, and enhances stability under the action of water surface tension; increases the effective coverage area of ​​the horizontal surface close to the water, and has a significant evaporation suppression effect.

Under this ratio, the device has large buoyancy and small weight gain, and is suitable for river basins or reservoirs with weak wind areas and slow water flow rates.

[0036] The thickness of the external cavity 1 is 2 mm, and it includes three layers of symmetrically arranged truncated cones of different diameters, which are the first truncated cone 2, the second truncated cone 3 and the third truncated cone 4 from top to bottom, and the diameters increase successively. The diameter of the lower bottom surface of the third truncated cone 4 is 200 mm, and the angle between the side slope and the horizontal plane is 85°. The upper bottom surfaces of the second truncated cone 3 and the third truncated cone 4 are connected by an arc, and the center angle of the arc is 80°. The arc connects the first truncated cone 2 and the second truncated cone 3. The diameter of the first truncated cone 2 is 90% of the diameter of the third truncated cone 4, and the vertical height of the external cavity 1 is 16.5% of the diameter of the third truncated cone 4. The slope and curvature of the outer side surface of each layer of the truncated cone of the external cavity 1 are consistent with the slope and curvature of the inner side surface of the groove interlayer 9.

[0037] The central water-filled cavity 5 includes a central cone 6 and an upper micro-curved surface 7 and a lower micro-curved surface 8 connected to the upper and lower sides of the central cone 6 by a vertex arc. The central angle of the vertex arc is 76°, and the diameter of the central cone 6 is 20% of the diameter of the third cone 4.

The reinforcing belt IV is not connected to the drainage hole III and the front and rear ends are smoothly connected to the groove interlayer 9.

[0040] Example 2

[0041] The present embodiment provides a dynamically water-filled wheeled water surface evaporation suppression device, which is blow-molded in one piece using polyethylene material, and consists of an external cavity 1, a central water-filled cavity 5, and a groove interlayer 9 located between the two parts; the specific structure is the same as that of Embodiment 1, and the only difference therefrom is that the minimum diameter ratio of the external cavity 1, the groove interlayer 9, and the central water-filled cavity 5 is 2:1:7. Under this ratio, the buoyancy of the device is small but the weight is increased, and the device is suitable for river basins or reservoirs with strong winds and turbulent water flow rates.

[0042] Therefore, the present invention adopts the above-mentioned automatic water-filling wheeled water surface evaporation suppression device, which has a simple structure and is easy to use.
