[0035] The terms used in the present invention are those general terms currently widely used in the art considering the functions of the present invention. However, these terms can change according to the intentions of those of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms can be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.

[0036] Refer to Figure 1, this embodiment provides a self - regulating photovoltaic power generation device on the water surface, including a support component 1 for supporting a rotating component 2.

[0037] In an embodiment provided by this application, referring to Figure 1 , the support component 1 includes a fixed rod 11 which is fixedly arranged and perpendicularly fixed on the bottom foundation. Preferably, two sets of support components 1 are provided, respectively located on both sides of the rotating component 2.

[0038] The fixed rod 11 is adjacent to a movable rod 12. One side of the movable rod 12 is provided with a rack, and the movable rod 12 is adapted to move up and down; the movable rod 12 can move up and down under the drive of a drive component 3.

[0039] In an embodiment provided by this application, referring to Figure 1 , one end of the rotating component 2 is hinged to the movable rod 12, and the other end of the rotating component 2 is hinged to the fixed rod 11. The rotating component 2 rotates relative to the fixed rod 11 driven by the movable rod 12.

[0040] Specifically, a baffle 23 is fixedly connected to the rotating component 2. The baffle 23 rotates synchronously with the rotating component 2. The initial setting position of the baffle 23 is perpendicular to the ground. As the rotating component 2 rotates, the baffle 23 rotates from a position perpendicular to the ground to a position parallel to the ground.

[0041] When the baffle 23 needs to be rotated, the drive component 3 drives the movable rod 12 to move downward. The movable rod 12 drives the rotating component 2 to rotate along the hinge point of the second rotating rod 22 and the fixed rod 11. When the second rotating rod 22 rotates to 90 degrees, the baffle 23 reaches a position parallel to the ground. During this process, the movable rod 12 will simultaneously shift towards the fixed rod 11. Referring to Figure 4 .

[0042] In an embodiment provided by this application, referring to Figure 1 , the drive component 3 includes a housing 31 which is fixed on the ground foundation and has an opening on the side adjacent to the movable rod 12 so that a gear (324) meshes with the rack structure of the movable rod 12. A gear assembly 32 is arranged inside the housing 31. The gear assembly 32 is adapted to the movable rod 12 and provides power for the up - and - down movement of the movable rod 12.

[0043] In an embodiment provided by this application, referring to Figures 1 to 4 , the rotating component 2 includes a first rotating rod 21. One end of the first rotating rod 21 is hinged to the movable rod 12, and the other end of the first rotating rod 21 is fixedly connected to a second rotating rod 22. The end of the second rotating rod 22 far from the first rotating rod 21 is hinged to the fixed rod 11.

[0044] In an embodiment provided by this application, referring to Figure 1, the length of the first rotating rod 21 is greater than that of the second rotating rod 22, and the included angle between the first rotating rod 21 and the second rotating rod 22 is set at 70 to 80 degrees.

[0045] Among them, the length of the first rotating rod 21 is 1.2 to 1.3 times that of the second rotating rod 22. The first rotating rod 21 and the second rotating rod 22 are arranged in a checkmark shape and are hinged to the support member 1.

[0046] In an embodiment provided by the present application, referring to Figure 1 , the bottom surface of the moving rod 12 is higher than the bottom surface of the fixed rod 11. A gap is reserved between the moving rod 12 and the ground foundation to provide space for the moving rod 12 to move downward.

[0047] In another embodiment provided by the present application, referring to Figure 5 , the rotating member 2 includes a third rotating rod 24. The third rotating rod 24 is arranged in a straight plate shape. The baffle 23 is fixedly connected to the third rotating rod 24, and the included angle between the baffle 23 and the third rotating rod 24 is set at 45 degrees.

[0048] Further, initially, the included angle between the third rotating rod 24 and the fixed rod 11 is set at 45 degrees.

[0049] When the baffle 23 needs to be rotated, the driving member 3 drives the moving rod 12 to move downward. The moving rod 12 drives the rotating member 2 to rotate along the hinge point of the third rotating rod 24 and the fixed rod 11. When the third rotating rod 24 rotates 90 degrees, the baffle 23 reaches a position parallel to the ground. During this process, the moving rod 12 will simultaneously shift towards the fixed rod 11. Referring to Figure 5 .

[0050] In an embodiment provided by the present application, referring to Figure 1 ,

[0051] The gear assembly 32 includes a hanging plate 321. The hanging plate 321 is arranged below the top wall of the housing 31. A pin shaft hole is provided on the hanging plate 321, and a connecting rod 328 is hinged to the hanging plate 321 through a pin shaft.

[0052] The other end of the connecting rod 328 is provided with a through hole, and a gear shaft 323 is hinged in the through hole. A gear 324 is fixedly installed on the gear shaft 323. The gear 324 meshes with the moving rod 12. A push rod 325 is fixedly installed on the side of the gear 324. Pushing the push rod 325 can make the gear 324 rotate. When the angle of the baffle 23 needs to be changed, push the push rod 325 to make the gear 324 rotate. The gear 324 drives the moving rod 12, and the moving rod 12 drives the rotating member 2 to rotate to change the angle of the baffle 23.

[0053] Further, referring to Figure 1, a first limiting rib 326 and a second limiting rib 327 are further provided on the gear 324. The first limiting rib 326 and the second limiting rib 327 are on the same side as the push rod 325. The first limiting rib 326 and the second limiting rib 327 are respectively located on both sides of the connecting rod 328. During the process of rotating the gear 324, after the first limiting rib 326 or the second limiting rib 327 contacts the connecting rod 328, the rotation of the gear 324 will stop, and the push rod can only be pushed in the reverse direction. The first limiting rib 326 and the second limiting rib 327 are provided to limit the rotation distance of the gear 324, and the rotation distance of the gear 324 limits the up and down movement amount of the moving rod 12.

[0054] Furthermore, a reset member 322 is provided at the hinge joint of the hanging plate 321 and the connecting rod 328. The reset member 322 is set as a reset spring. The reset member 322 is prefabricated to always drive the gear 324 to approach the moving rod 12. When the moving rod 12 moves up and down, it will have a lateral offset driven by the rotating member 2. The reset member 322 can keep the gear 324 and the moving rod 12 in a meshing state all the time.

[0055] The push rod 325 of this device can also be driven by a motor.

[0056] The present invention also provides a wind baffle device, which includes the aforementioned baffle rotating mechanism, and a wind baffle assembly 4. The wind baffle assembly 4 includes several groups of rotating members 2, and the rotating members 2 are sequentially hinged to the supporting member 1 from top to bottom. Refer to Figures 6 to 8 . As the moving rod 12 moves up and down, it can simultaneously drive the aforementioned array of baffles 23 to change from a position perpendicular to the ground to a position parallel to the ground or perpendicular to the ground again.

[0057] It should be noted that according to the natural environment of the location where the cooling water tower m is located, several groups of this device can be set. A semi-circular windbreak can be formed on the windward side of the cooling water tower m, or this device can be set on the entire outer peripheral side of the cooling water tower m at the same time to improve the windproof effect; when the temperature rises, the baffle 23 is rotated to a state parallel to the ground to facilitate the cooling of the cooling water tower m. Refer to Figure 9 .

[0058] In an embodiment provided by the present application, refer to Figure 6 , this device further includes a support column 5. The support column 5 is fixedly connected to the cooling water tower m. A top plate 6 is fixed on one side of the support column 5. The top plate 6 can prevent snow from falling into the lower part of the cooling water tower m. Refer to Figure 10 , the height of the top plate 6 gradually decreases from the support column 5 to the fixed rod 11 to prevent snow water and the like from remaining on its top surface.

[0059] One end of the top plate 6 away from the support column 5 is fixedly connected to the top surface of the fixed rod 11.

[0060] For cooling water towers located in alpine regions, due to the cold winters with long durations and large day-night temperature differences, the minimum temperature can reach -30°C to -40°C. During winter, when two units operate with the cylinder cut-off and the circulating water system operates with two units sharing one tower, the original anti-freezing measure designed for the cooling water tower is to manually hang windshields. During the maintenance period of the cooling water tower in winter, the operating personnel need to conduct regular inspections of the cooling water tower every shift. The maintenance personnel of the cooling water tower need to remove and hang the windshields and de-ice the cooling water tower according to the weather changes in winter. Once the operation is not timely, the cooling water tower is extremely vulnerable to freezing hazards, and the repetitive labor intensity of the personnel is high.

[0061] After the cooling water tower freezes, it affects the ventilation inside the cooling water tower, reduces the efficiency of the cooling water tower, gradually increases the circulating water temperature, and thus reduces the vacuum degree of the condenser. After the concrete structure of the cooling water tower is damaged by freeze-thaw, it will have a greater impact on the strength of the concrete. In addition, due to the ice formation on the water spraying device, it bears a large overload and even the collapse of the water spraying filler and bracket, increasing a large amount of maintenance costs every year.

[0062] For example: A certain cooling water tower uses this device to block the wind. To reduce the investment cost, it is only installed on the inlet side this time. During the winter operation, the opening and closing of the windshield are controlled according to the outdoor temperature, avoiding the manual removal and hanging of the windshield. This can greatly improve the safety index of the operators, reduce the labor intensity of the maintenance personnel, save maintenance costs, improve the adjustment rate of the cooling water tower, ensure the operating parameters of the circulating water in winter, and meet the requirements of safe and economic operation with operability.

[0063] Using this device to adjust the winter air intake of the cooling water tower, keeping the circulating water temperature constant (between 8°C and 18°C), ensuring the vacuum degree of the unit, and improving the unit efficiency; avoiding damage to the cooling water tower filler, filler bracket, and concrete beams and columns.

[0064] By measuring the wind speed and direction, the actual air intake area of the inlet on the windward side is adjusted in real time to timely compensate for the influence of the side wind on the heat dissipation effect of the cooling water tower and keep the internal flow field of the cooling water tower uniform and symmetric.

[0065] By measuring the temperature of the circulating water inside the cooling water tower, the feedforward control of the windshield is realized, timely intervening in the change trend of the circulating water temperature, and then achieving the purpose of cold protection and controlling the circulating water temperature within the optimal temperature range. When the water temperature drops (according to trend analysis), the windshield is partially closed (reducing the inlet area); when the water temperature rises, the number of half-open baffles is increased (increasing the inlet area), thus completing the adjustment of the air intake volume and eliminating the internal icing of the cooling water tower.

[0066] By adjusting the intake air volume in the cooling water tower, excessive cold air is prevented from taking away the heat of the circulating water, thus playing a role in preventing the cooling water tower from freezing. More importantly, the temperature of the circulating water is controlled to be stable within the set range, the efficiency of the steam turbine is improved, and the unit operates economically under the best working conditions.

[0067] After the cooling water tower is transformed by using this device, problems such as ice formation during winter operation of the cooling water tower, which affects the ventilation in the cooling water tower and reduces the efficiency of the cooling water tower, freeze-thaw damage to the concrete of the cooling water tower, potential hazards of collapse of the water distribution device and support beams due to ice formation, and safety hazards posed by falling ice at the top of the cooling water tower to operation and maintenance personnel can be solved. The operating parameters of the cooling water tower are improved, the efficiency of the cooling water tower is increased, the good economic operation of the unit is ensured, and the safety hazards of the cooling water tower are eliminated.

[0068] Finally, it should be noted that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
