Description

Technical Field

[0001] This utility model relates to the field of water surface photovoltaic power generation technology, specifically to an anchoring structure for a floating photovoltaic power station. Background Technology

[0002] Most commonly used floating photovoltaic power stations adopt precast pile foundation support, and the vast majority of fish-solar complementary photovoltaic power station projects also adopt this scheme. However, when the water depth exceeds 3m, it is difficult to implement the precast pile foundation scheme. As the water depth increases, the economic efficiency of this scheme becomes worse. Moreover, the precast pile scheme cannot be implemented in unstable water conditions such as coal mining subsidence areas. Therefore, in deeper water environments such as reservoirs, large fish ponds, and coal mining subsidence areas, floating floating photovoltaic support systems should be used.

[0003] Currently, most floating photovoltaic power stations use a combination of anchor ropes and anchors for anchoring, resulting in large swaying angles and poor stability of the photovoltaic platform under the impact of water flow. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides an anchoring structure for a floating photovoltaic power station to solve the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anchoring structure for a floating photovoltaic power station, comprising a photovoltaic platform and anchor chains set at the four corners of the bottom of the photovoltaic platform, each anchor chain having a counterweight at its bottom and an elastic sleeve rod in the middle of each anchor chain.

[0008] Preferably, the bottom of the counterweight is fixedly connected with multiple insert rods.

[0009] Preferably, a turntable is rotatably connected to the top of the counterweight, fan blades are provided on the outer peripheral wall of the turntable, a drive rod is fixedly connected to the bottom of the turntable, multiple vertical grooves are opened in the drive rod, vertical plates are slidably connected in the vertical grooves, and a drill rod is fixedly connected to the multiple vertical plates. An opening is opened in the middle of the counterweight for the drive rod and the drill rod to pass through, a guide groove is provided in the opening, and a guide ball is provided on the outer peripheral wall of the drill rod.

[0010] Preferably, the elastic sleeve includes an outer sleeve and an inner sleeve, the inner sleeve is embedded in the outer sleeve, and a spring is provided inside the outer sleeve, the spring abutting against the bottom of the inner sleeve.

[0011] Preferably, an airbag is provided on the outer peripheral wall of the photovoltaic platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Firstly, the elastic sleeve can buffer the force of the slow movement, reduce the tilt angle of the photovoltaic platform, and further improve the stability of the photovoltaic platform on the water surface.

[0014] Secondly, when the river is turbulent, the undercurrent in the water can drive the turntable to rotate through the fan blades. The turntable drives the drive rod to rotate synchronously. The drive rod rotates through the interlocking effect between the vertical groove and the vertical plate. The drive rod moves downwards while rotating through the trajectory of the guide ball in the guide groove, thereby increasing the depth of the drill rod in the riverbed and improving the stability of the counterweight at the bottom of the water.

[0026] Example

[0027] Please see Figure 1-7 This utility model provides an anchoring structure for a floating photovoltaic power station, including a photovoltaic platform 1 and anchor chains 2 set at the four corners of the bottom of the photovoltaic platform 1. Each anchor chain 2 is provided with a counterweight block 3 at the bottom and an elastic sleeve rod 4 in the middle of each anchor chain 2.

[0028] Four counterweights 3 sink to the bottom of the water, forming a stable tension and fixing structure for the photovoltaic platform 1, which improves the stability of the photovoltaic platform 1 on the water surface. At the same time, when the photovoltaic platform 1 shakes, the elastic sleeve 4 can buffer the force of the slow movement, reduce the tilt angle of the photovoltaic platform 1, and further improve the stability of the photovoltaic platform 1 on the water surface.

[0029] Multiple insert rods 301 are fixedly connected to the bottom of the counterweight 3. The insert rods 301 are used to improve the stability of the counterweight 3 on the riverbed.

[0030] The top of the counterweight 3 is rotatably connected to a turntable 302. A fan blade 303 is provided on the outer peripheral wall of the turntable 302. A drive rod 304 is fixedly connected to the bottom of the turntable 302. Multiple vertical grooves 305 are opened in the drive rod 304. Vertical plates 306 are slidably connected in the vertical grooves 305. A drill rod 307 is fixedly connected to the multiple vertical plates 306. An opening 309 is opened in the middle of the counterweight 3 for the drive rod 304 and the drill rod 307 to pass through. A guide groove 308 is provided in the opening 309. A guide ball 310 is provided on the outer peripheral wall of the drill rod 307.

[0031] Specifically: When the river is turbulent, the undercurrent in the water can drive the turntable 302 to rotate through the fan blade 303. The turntable 302 drives the drive rod 304 to rotate synchronously. The drive rod 304 rotates through the interlocking effect between the vertical groove 305 and the vertical plate 306. The drive rod 304 moves downward while rotating through the trajectory of the guide ball 310 in the guide groove 308, thereby increasing the depth of the drill rod 307 on the riverbed and improving the stability of the counterweight 3 on the bottom of the water.

[0032] The elastic sleeve 4 includes an outer sleeve and an inner sleeve. The inner sleeve is embedded in the outer sleeve, and a spring is provided inside the outer sleeve. The spring abuts against the bottom of the inner sleeve.

[0033] An airbag 101 is provided on the outer peripheral wall of the photovoltaic platform 1. The airbag 101 is used to enhance the buoyancy of the photovoltaic platform 1.
