Description

Technical Field

[0001] The present invention relates to the fields of environmental technology and water resource technology, and particularly relates to a floating anti-evaporator for water surface. Background Art

[0002] Water is an important component of the earth's environment and a basic element for the survival of humans and all living things. Although the total amount of water on the earth is not small, the amount of fresh water resources available for human use is far less than 0.3%. In the arid regions of northwestern China, the annual evaporation of water is much greater than the annual precipitation. Some lakes are drying up and shrinking rapidly. At the same time, there are also a large number of free water surface storage projects in the water-lifting irrigation projects in the northwestern region. The large evaporation of water bodies causes waste of water resources and electric energy; generally speaking, the cost of storing electricity is relatively high. Compared with traditional electricity storage technologies, pumped-storage power stations have many advantages. They not only have the function of storing electricity, but also store water in the upper reservoir. They improve the power structure and enhance the regulation of the power grid. However, the evaporation of water in the reservoir not only wastes a great deal of water resources, but also wastes electric energy. The land evaporation is relatively high. The annual evaporation in the northwestern region reaches 1000-2600 mm, and the average annual precipitation is 235 mm. The main evaporation occurs on the water surface of the basin and reservoir. Evaporation is an important channel for wasting water resources. This patent is designed to prevent water surface evaporation. It serves natural and artificial water environment waters such as water-lifting irrigation storage projects, facility agriculture and aquaculture, pumped-storage power station reservoirs, ecological environment and water treatment, and solves the problem that it is relatively difficult to effectively prevent water surface evaporation in the existing technology. Summary of the Invention

[0003] The purpose of the present invention is to provide a reasonably designed floating anti-evaporator for water surface in view of the defects and deficiencies of the prior art, which can effectively utilize the power of natural rivers and floating cavities to form negative pressure and achieve effective control, and can maintain its own balance while achieving the purpose of preventing water surface evaporation.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions: It includes an upper structure and a lower structure;

[0005] The above-mentioned upper structure is composed of a magnetic attraction structure, a lotus leaf top cover, a support and diversion rod, a spherical rope clamping device, a fixed ball, and an energy dissipation conical grid; the middle part of the lotus leaf top cover is a positive conical convex hollow structure; the magnetic attraction structure is fixed on the bottom surface of the periphery of the lotus leaf top cover; several support and diversion rods are connected through the bottom surface of the lotus leaf top cover in a penetrating manner, and the support and diversion rods are arranged in a hollow structure, and several support and diversion rods are arranged in a converging structure from top to bottom; on the bottom surface of the lotus leaf top cover located at the center of several support and diversion rods, several energy dissipation conical grids with a hollow structure are fixed, and the bottoms of several energy dissipation conical grids are connected into one body by a fixed ball, and a spiral blade is arranged in each energy dissipation conical grid, and a spherical rope clamping device is clamped in the fixed ball, and a curved rope clamping groove is arranged in the spherical rope clamping device;

[0006] The above-mentioned lower structure is composed of a fixing bolt, a balance ball, a flexible steel rope, a rope connecting device, a floating cavity, and a floating cavity top cover; the floating cavity top cover is covered and fixedly connected to the top of the floating cavity by several fixing bolts, and the lower ends of several support and diversion rods are connected through the floating cavity top cover in a penetrating manner, the floating cavity is arranged in an inverted conical hollow structure, a balance ball is movably arranged in the floating cavity, the flexible steel rope is arranged in the curved rope clamping groove, and both ends of the flexible steel rope are connected with a rope connecting device.

[0007] Further, the rope connecting device is composed of a male rope connecting structure, a female rope connecting structure, and a rope connecting plug ball; the end of the flexible steel rope and the end of the external connecting wire respectively pass through the male rope connecting structure and the female rope connecting structure and are fixed to the rope connecting plug ball, and the male rope connecting structure is inserted and fixed by matching the dovetail clamping block on the end face with the dovetail clamping groove on the end face of the female rope connecting structure.

[0008] Further, a waterproof layer is coated on the outside of the middle part of the lotus leaf top cover which is a positive conical convex hollow structure.

[0009] Further, several papilla particles are arranged on the outer surface of the middle part of the lotus leaf top cover which is a positive conical convex hollow structure, the distance between adjacent papilla particles is 12 micrometers, the diameter of the papilla particles is 200 nanometers, and the protruding height of the papilla particles is 5-9 micrometers.

[0010] The working principle of the present invention:

[0011] Adjusting the placement direction and balance in water: After placing the floating prevention evaporator in water, due to the design of the floating cavity with an inverted conical structure, the lotus leaf top cover, and the energy dissipation conical grid with a hollow structure, it automatically floats on the water surface under the action of buoyancy. Since the top of the lotus leaf top cover is a positive conical protrusion and the side wall is designed vertically along the perimeter, and the floating cavity is an inverted conical design, the balance ball is in a moving state after entering the water body. Under the guidance of the internal structure of the floating cavity, it finally stays at the bottom of the inverted cone at the lower part of the floating cavity. The outside of the balance ball is coated with a waterproof material of a certain thickness. The structure of the balance ball and the inverted conical floating cavity together complete the adjustment of the position of the prevention evaporator automatically on the water surface. At the same time, due to the hollow design of the energy dissipation conical grid, under the action of water flow, the water flows mix with each other, generating energy dissipation and forming a certain degree of local vacuum, which further speeds up the adjustment of the placement position of the prevention evaporator in water. And the design of the flexible steel rope and the magnetic attraction structure at the edge of the lotus leaf top cover promotes the overall balance, that is, the inverted conical structure of the floating cavity of the prevention evaporator, the movement law of the balance ball, and the energy dissipation conical grid with an inverted conical layout promote the position adjustment of the prevention evaporator, as well as the design of the flexible steel rope and the magnetic attraction structure. Finally, the balance ball stays at the bottom of the inverted cone of the floating cavity, and the structural design of the prevention evaporator maintains the short-term balance of the prevention evaporator in water, without tilting and being in a positive position. Since the position of the energy dissipation conical grid is at the upper part of the inverted conical floating cavity, when the inverted conical floating cavity adjusts its position in water, all the structures below the lotus leaf top cover enter the water body, enhancing the overall balance of the prevention evaporator;

[0012] Preventing water retention:

[0013] After the prevention evaporator is placed in water, due to the design of the floating cavity, it automatically floats on the water surface under the action of buoyancy. The lotus leaf top cover is closely attached to the water surface. The whole body of the lotus leaf top cover is made of antioxidant plastic, and the lotus leaf top cover is designed with an upward convex curved surface (that is, the middle is a positive conical protrusion-shaped hollow structure), preventing water from sticking. The water will slide down along the papillae and finally flow to the water surface, thus reducing the evaporation of water volume. The middle of the lotus leaf top cover is a positive conical protrusion-shaped hollow structure, the side wall is designed vertically along the circumference, and magnetic attraction structures are embedded around it, which can better connect adjacent devices;

[0014] Contact between the lotus leaf top cover and the water surface:

[0015] The energy dissipation conical grid is a hollow structure, which can form a channel for water wave circulation. Under the action of water flow, the spiral flow channel on the energy dissipation conical grid generates an upward lifting force. The water flow moves upward and collides with the lower part of the lotus leaf top cover. And the water flow passing through the hollow structure mixes with the water flow in the positive conical protrusion-shaped hollow structure in the middle of the lotus leaf top cover and dissipates energy. The formed vortex flows into the space below the lotus leaf top cover, also forming energy dissipation, and can form a certain degree of local vacuum in the lotus leaf top cover, ensuring the water absorption effect of the device, and thus playing a role in closely attaching to the water surface;

[0016] The spherical rope clamp fixes the flexible steel rope:

[0017] After the evaporator is placed in water, the flexible steel rope is connected to adjacent equipment, and the spherical rope clamp is used to fix the flexible steel rope. That is, the spherical rope clamp holds the flexible steel rope through the curved rope clamping groove in the spherical surface, thereby achieving the purpose of fixing the flexible steel rope. The openings of the curved rope clamping grooves are located in different orientations, and adjacent curved rope clamping grooves do not cross each other, so that both flexible steel ropes are fixed at independent curved rope clamping grooves. The curved rope clamping grooves make the flexible steel ropes more stable under the action of the fluid, and they do not cross each other and do not affect each other;

[0018] The rope splicer connects the flexible steel ropes of adjacent equipment:

[0019] To prevent water surface evaporation, due to the connection of multiple water surface floating evaporators, different water surface floating evaporators are connected and fixed to each other by flexible steel ropes and magnetic attraction structures. Different water surface floating evaporators need to rely on rope splicers to connect the flexible steel ropes. The male clamping structure of the rope splicer of one water surface floating evaporator is clamped on the female clamping structure of the rope splicer of another water surface floating evaporator, thereby connecting the flexible steel ropes of different water surface floating evaporators. The wire inserting ball of the rope splicer can well prevent the entanglement of the rope when the flexible steel rope rotates.

[0020] After adopting the above structure, the beneficial effect of the present invention is: The present invention provides a water surface floating prevention evaporator, which effectively utilizes the power of natural rivers and floating cavities to form negative pressure and achieve effective control. While being able to maintain its own balance, it can also achieve the purpose of preventing water surface evaporation. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The above lower structure is composed of a fixed bolt 6, a balance ball 7, a flexible steel rope 8, a rope connector 9, a floating cavity 10, and a floating cavity top cover 11; the floating cavity top cover 11 is covered and fixedly connected to the top of the floating cavity 10 by several fixed bolts 6, the lower ends of several support and diversion rods 3 are connected through holes on the floating cavity top cover 11, the floating cavity 10 is arranged as an inverted conical hollow structure, a balance ball 7 is movably arranged in the floating cavity 10, the flexible steel rope 8 is threaded in the curved rope clamping groove 4-1, and both ends of the flexible steel rope 8 are connected with a rope connector 9; the rope connector 9 is composed of a male rope connector structure 13, a female rope connector structure 14, and a rope connector plug ball 15; the end of the flexible steel rope 8 and the end of the external connecting wire respectively pass through the male rope connector structure 13 and the female rope connector structure 14 and are fixed to the rope connector plug ball 15, and the male rope connector structure 13 is inserted and fixed by matching the dovetail clamping block 13-1 on the end face with the dovetail clamping groove 14-1 on the end face of the female rope connector structure 14.

[0042] The working principle of this specific embodiment:

[0043] Adjusting the placement direction and balance in water: After placing the floating prevention evaporator in water, due to the design of the floating cavity 10 with an inverted conical structure, the lotus leaf top cover 2, and the energy dissipation conical grid 12 with a hollow structure, it automatically floats on the water surface under the action of buoyancy. Since the top of the lotus leaf top cover 2 is a forward conical protrusion and the side wall is designed vertically along the perimeter, and the floating cavity 10 is designed as an inverted cone, the balance ball 7 is in a moving state after entering the water body. Under the guidance of the internal structure of the floating cavity 10, it finally stays at the bottom of the lower inverted cone of the floating cavity 10. A waterproof material with a certain thickness is coated on the outside of the balance ball 7. The structure of the balance ball 7 and the inverted conical floating cavity 10 together complete the adjustment of the position of the prevention evaporator automatically adjusted on the water surface. At the same time, due to the hollow design of the energy dissipation conical grid 12, under the action of water flow, the water flows mix with each other, generating energy dissipation and forming a certain degree of local vacuum, which further accelerates the adjustment of the placement position of the prevention evaporator in water. Moreover, the design of the flexible steel cable 8 and the magnetic attraction structure 1 at the edge of the lotus leaf top cover 2 promotes the overall balance, that is, the inverted conical structure of the floating cavity 10 of the prevention evaporator, the movement law of the balance ball 7, and the energy dissipation conical grid 12 with an inverted conical layout promote the position adjustment of the prevention evaporator, and the design of the flexible steel cable 8 and the magnetic attraction structure 1. Finally, the balance ball 7 stays at the bottom of the inverted cone of the floating cavity 10. The structural design of the prevention evaporator maintains the short-term balance of the prevention evaporator in water and does not tilt but is in a forward position. Since the position of the energy dissipation conical grid 12 is at the upper part of the inverted conical floating cavity 10, when the inverted conical floating cavity 10 adjusts its position in water, all the structures below the lotus leaf top cover 2 enter the water body, enhancing the overall balance of the prevention evaporator; The principle is as Figure 13 ;

[0044] Preventing water retention:

[0045] After the prevention evaporator is placed in water, due to the design of the floating cavity 10, it automatically floats on the water surface under the action of buoyancy. The lotus leaf top cover 2 is closely attached to the water surface. The whole body of the lotus leaf top cover 2 is made of antioxidant plastic. The lotus leaf top cover 2 is designed with an upward convex curved surface (that is, the middle is a forward conical protrusion-shaped hollow structure), which prevents water from sticking. The water will slide down along the papillae and finally flow to the water surface, thus reducing the evaporation of water volume; The middle of the lotus leaf top cover 2 is a forward conical protrusion-shaped hollow structure, the side wall is designed vertically along the circumference, and magnetic attraction structures 1 are embedded around it, which can better connect adjacent devices;

[0046] Contact between the lotus leaf top cover and the water surface:

[0047] The energy dissipation conical grid 12 is a hollow structure that can form a channel for water wave circulation. Under the action of water flow, the spiral flow channels on the energy dissipation conical grid 12 generate an upward lifting force. The upward moving water collides with the lower part of the lotus leaf top cover 2, and the water flowing through the hollow structure mixes with the water in the positive conical convex hollow structure in the middle of the lotus leaf top cover 2 and dissipates energy. The formed vortex flows into the space below the lotus leaf top cover 2, also dissipating energy, and can form a certain degree of local vacuum inside the lotus leaf top cover 2 to ensure the water absorption effect of the device, thereby playing a role in closely adhering to the water surface. The principle is as Figure 14 ;

[0048] The spherical rope clamp fixes the flexible steel rope:

[0049] After the evaporator is placed in water, it is connected to adjacent devices with a flexible steel rope 8. The spherical rope clamp 4 is used to fix the flexible steel rope 8. That is, the spherical rope clamp 4 holds the flexible steel rope 8 through the curved rope clamping groove 4-1 in the spherical surface, thereby achieving the purpose of fixing the flexible steel rope 8. The openings of the curved rope clamping grooves 4-1 are in different orientations, and adjacent curved rope clamping grooves 4-1 do not cross each other, so that both flexible steel ropes 8 are fixed at independent curved rope clamping grooves 4-1. The curved rope clamping grooves 4-1 make the flexible steel ropes 8 more stable under the action of the fluid and do not cross each other and do not affect each other. The principle is shown in Figure 15;

[0050] The rope splicer connects the flexible steel ropes of adjacent devices:

[0051] To prevent water surface evaporation, multiple water surface floating evaporator preventers need to be connected. Different water surface floating evaporator preventers are connected and fixed to each other by a flexible steel rope 8 and a magnetic attraction structure 1. Different water surface floating evaporator preventers need to be connected to the flexible steel rope 8 by a rope splicer 9. The male card structure 13 of the rope splicer of one water surface floating evaporator preventer is clamped on the female card structure 14 of the rope splicer of another water surface floating evaporator preventer, thereby connecting the flexible steel ropes 8 of different water surface floating evaporator preventers. The wire inserting ball 15 of the rope splicer can well prevent the entanglement of the rope when the flexible steel rope rotates.

[0052] After adopting the above structure, the beneficial effects of this specific embodiment are as follows:

[0053] 1. Utilize the inverted conical floating cavity, the balance ball in the cavity, the flexible steel rope, and the spiral blades embedded in the energy dissipation conical grid to achieve the floating and balance of the water surface evaporator preventer;

[0054] 2. Utilize the movement of the inverted conical floating cavity of the floating cavity and the balance ball to achieve the automatic adjustment of the placement position of the water surface evaporator preventer;

[0055] 3. By mixing the water flow through the hollow structure with the water flow in the hollow structure with a forward conical convex shape in the middle of the lotus leaf top cover, energy dissipation is generated, and vortices are formed and flow into the space below the lotus leaf top cover to form a certain degree of local vacuum, thereby ensuring the water absorption effect of the device, and then the lotus leaf top cover closely adheres to the water surface;

[0056] 4. With the design of the spherical rope clamp, the curved rope clamping groove for fixing the flexible steel rope, and the design of the lotus leaf top cover and the magnetic attraction structure, it can be better connected to adjacent devices;

[0057] 5. The structure of the rope splicer is conducive to the connection of the flexible steel ropes of adjacent devices, and then different devices can be connected;

[0058] 6. While enhancing the buoyancy of the thruster by using the energy dissipation conical grid, the leaf shape structure is conducive to forming a stable floating state;

[0059] 7. The middle of the lotus leaf top cover bulges upward, the whole body is made of antioxidant material, there is a certain space below, the design of the middle bulge is conducive to forming a certain degree of local vacuum, the surface of the lotus leaf top cover is designed with papilla-like particle structures with a size of 5-9 microns, the spacing between them is 12 microns, and the diameter of the papilla is 200 nanometers; or the surface is made of a water-repellent material, or a water-repellent material is added to the anti-oxidation material on the top surface.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

The male clamping structure (13) of the rope splicer of one water surface floating evaporator is clamped on the female clamping structure (14) of the rope splicer of another water surface floating evaporator, so as to connect the flexible steel ropes (8) of different water surface floating evaporators. The wire inserting ball (15) of the rope splicer can well prevent the rope from winding when the flexible steel rope rotates.
