Description

Technical Field

[0001] The utility model 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] Reservoirs in arid plains are subject to specific natural environmental influences, resulting in significant seasonal variations in storage capacity and significant annual water losses due to ineffective evaporation. Under the influence of long days, high radiation levels, large temperature swings, and strong winds, the water body experiences large temperature fluctuations between day and night. The resulting vapor pressure difference is the primary cause of ineffective evaporation losses in large water bodies in arid plains. Addressing evaporation losses caused by temperature swings, wind speeds, and radiation will significantly improve water utilization.

[0003] Currently, the main methods for suppressing ineffective evaporation from water bodies include physical covering, chemical reagents, biological covering, and physical shielding. The first three primarily work by reducing the effects of radiation and temperature, while the latter primarily works by reducing the influence of wind speed. All are highly effective. Physical covering, due to its ease of operation, has become the most commonly used suppression method. Physical covering is friendly to water quality and the environment, and its effectiveness has led to the development of various covering materials, including floats, polystyrene panels, and photovoltaic panels. Among these covering materials, floats are widely used in large reservoirs both domestically and internationally due to their simple structure, low cost, and easy installation. However, their drawbacks should not be ignored, such as their tendency to roll in wind and waves, exposing the wetted surface and reducing evaporation suppression efficiency, as well as low surface utilization efficiency.

[0004] In view of the above problems, the utility model provides a wheeled water surface steam suppression device which is automatically filled with water. Utility Model Content

[0005] The purpose of the utility model 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 a wheeled water surface steam suppression device that automatically fills with water. The wheeled water surface steam suppression device is an integrated structure, comprising an external cavity, a central water-filled cavity, and a groove interlayer formed therebetween.

[0007] The external cavity comprises three 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] The bottom of the recessed sandwich is provided with a reinforcing belt, and the two sides of the recessed sandwich are provided with drainage holes through the diametrically symmetric arrangement.

[0010] Preferably, the three-layer different-diameter circular cones are sequentially the first circular cone, the second circular cone and the third circular cone from top to bottom; the lower base of the third circular cone has a diameter of 100-600 mm, and the included angle between the side slope and the horizontal plane is greater than 85°; the upper base of the second circular cone and the third circular cone are connected through a circular arc transition; the central angle of the circular arc is less than 90°; the first circular cone and the second circular cone are connected in sequence along the circular arc; and the diameter of the first circular cone is 70-90% of the diameter of the third circular cone.

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

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

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

[0014] Preferably, the hole diameter of the water inlet hole and the air outlet hole is 5-10 mm.

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

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

[0017] In the preparation of the automatic water-filled wheeled water surface evaporation suppression device, different diameters need to be selected according to different water area, which can effectively improve the coverage rate of the water surface and improve the evaporation suppression effect; when the groove proportion of the fixed weight and backflow design is increased, the buoyancy can be enhanced by enlarging the outer cavity and reducing the proportion of the central water-filled cavity, and vice versa, which is used for selecting the most suitable size according to different environments and improving the evaporation suppression effect.

[0018] The top corner arc processing, the circular table side, and the limitation of the central angle, the circular table side bottom corner and the horizontal plane included angle angle of the utility model have the following purposes: first, preventing top corner collision, reducing the stress of collision contact surface, increasing the anti-collision ability and enhancing the durability; second, ensuring the backflow effect after rainwater and spray, cooperating with the hydrophobic material and the drainage hole, fully playing the weight increasing effect while reducing the influence on the evaporation suppression effect; third, the height of the center, the gradually smooth height of both sides can improve the recovery of the stacked material in unexpected situations.

[0033] Example 1

[0034] like Figure 1-3 As shown, this embodiment provides a dynamically water-filled wheeled water surface evaporation suppression device, which is blow-molded as a whole 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; wherein, the minimum diameter ratio of the external cavity 1, the groove interlayer 9, and the central water-filled cavity 5 is 7:1:2. 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.

[0035] The thickness of the external cavity 1 is 2mm, and it contains three symmetrically arranged layers of cones of different diameters. From top to bottom, they are the first cone 2, the second cone 3, and the third cone 4, with increasing diameters. The lower base diameter of the third cone 4 is 200mm, and the angle between the side slope and the horizontal plane is 85°. The upper bases of the second cone 3 and the third cone 4 are connected by an arc with a central angle of 80°. The arc extends to connect the first cone 2 and the second cone 3. The diameter of the first cone 2 is 90% of the diameter of the third cone 4. The vertical height of the external cavity 1 is 16.5% of the diameter of the third cone 4. The slope and curvature of the outer side surfaces of each layer of cones in the external cavity 1 are consistent with the slope and curvature of the inner side surface of the groove interlayer 9.

[0036] 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 through a vertex arc. The central angle of the vertex arc is 76°, and the diameter of the central cone 6 is 20-95% of the diameter of the third cone 4. The overall vertical height of the central water-filled cavity 5 is 110% of the vertical height of the central cone 6.

[0037] A water inlet hole II is provided at the center of the lower micro-curved surface 8, and an exhaust hole I is provided at the center of the upper micro-curved surface 7; the diameters of the water inlet hole II and the exhaust hole I are 5 mm.

[0038] The thickness of the groove interlayer 9 is 10mm, and a reinforcing belt IV is provided at the bottom of the groove interlayer 9. Two symmetrical drainage holes III are provided on both sides of the groove interlayer 9 through the diameter, and the hole diameter is 5mm. The reinforcing belt IV is not connected to the drainage hole III and the head and tail ends are smoothly connected to the groove interlayer 9.

[0039] Example 2

[0040] 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 Example 1, the only difference being 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 gain is large, and the device is suitable for river basins or reservoirs with strong winds and turbulent water flow rates.

[0041] Therefore, the utility model adopts the above-mentioned automatic water-filling wheeled water surface evaporation suppression device, which has a simple structure and is easy to use. While automatically filling water and increasing weight to improve its own stability, it also takes into account the surface hydrophobic backflow and durability under collision, and can effectively prevent the superposition phenomenon, which can significantly reduce the ineffective evaporation loss of the water surface.
