Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a floating body fixing device of a floating photovoltaic power station. Background Art

[0002] Floating photovoltaic power stations on the water surface can effectively utilize the land resources on the water surface to achieve the purpose of photovoltaic power generation by installing photovoltaic panels on the floating array. The floating array is fixed on the water surface by an anchoring system. The conventional anchoring system adopts an anchoring foundation + anchor rope method for anchoring. The anchoring foundation can be a pile foundation or a gravity foundation. In actual projects, due to geological topography and construction quality problems, the anchoring points of the anchor ropes on the anchoring foundation are relatively inconsistent in spatial position, while the length of the anchor ropes and the connection points of the anchor ropes with the floating arrays are fixed, resulting in inconsistent force-bearing lengths of the anchor ropes of the anchoring system. When the floating array is subjected to wind and wave loads, stress concentration of the anchor ropes occurs, causing the anchor ropes to break, making the anchoring system of the floating array fail. Utility Model Content

[0003] In order to overcome the problem that in the daily operation of traditional floating photovoltaic power stations, the anchoring points of traditional floating photovoltaic power stations are relatively non-uniform in spatial position, while the length of the rope and the connection point between the rope and the floating body are fixed, resulting in rope stress concentration when the floating body is subjected to wind and wave loads.

[0004] The technical solution of the utility model is: a floating body fixing device of a floating photovoltaic power station, comprising a floating body array, a connecting component, a telescopic component, a reset component, a connecting component and a fixing component; a connecting component with a connecting function is arranged on one side of the floating body array, a telescopic component with a telescopic function is arranged on one side of the connecting component, a reset component with a reset function is arranged on the inner side of the telescopic component, a connecting component with a connecting function is arranged on the reset function side, and a fixing component with a fixing function is arranged at one end of the connecting component.

[0005] Preferably, the floating body array and the telescopic assembly are connected through the nested structure of the connecting assembly, and the telescopic movement of the telescopic assembly is driven by the telescopic movement of the elastic telescopic structure of the reset assembly, thereby increasing the force-bearing length of the connecting assembly, compensating for the inconsistent force length of the rope body caused by construction or other factors, and fixing one end of the connecting assembly by a fixing assembly.

[0006] Preferably, the connecting assembly includes a first connecting ring and a second connecting ring; the first connecting ring is arranged on one side of the floating body array, and the second connecting ring is arranged on one side of the first connecting ring. When in use, the position of the first connecting ring is fixed by the floating body array, and the position of the second connecting ring is fixed by nesting the second connecting ring and the first connecting ring.

[0007] Preferably, the telescopic assembly includes a protective sleeve and a telescopic rod; the protective sleeve is provided on one side of the second connecting ring, and the telescopic rod is provided on the inner side of the protective sleeve. When in use, the position of the telescopic rod is fixed by the protective sleeve.

[0008] Preferably, the reset assembly includes a reset spring and a third connecting ring; a reset spring is arranged on the outside of the telescopic rod, and a third connecting ring is arranged at one end of the telescopic rod. When in use, the reset spring and the telescopic rod are protected by a protective cover to prevent long-term wave erosion from causing significant wear to the elastic structure. The telescopic rod is used to prevent the reset spring from being twisted significantly when it is extended or retracted, and the telescopic rod is driven to extend or retract by the extension of the reset spring, thereby adjusting the position of the third connecting ring.

[0009] Preferably, the connection assembly also includes a fourth connecting ring and an anchor rope; a fourth connecting ring is provided on one side of the third connecting ring, and an anchor rope is provided on one side of the fourth connecting ring. When in use, when the device is subjected to wind and wave loads, the anchor rope with the shortest force on the device begins to be stressed, and the force on the anchor rope drives the reset spring to perform telescopic movement, and the stress length of the anchor rope is increased by the telescopic deformation of the reset spring, thereby compensating for the inconsistency of the stress length of the anchor rope caused by construction or other factors; it is assumed that there are n anchor ropes, the total tension borne by all anchor ropes under the action of wind and wave loads is F, the maximum stress length difference between the anchor ropes is Δx, and the elastic deformation coefficient of the reset spring is k. When the floating body array is subjected to wind and wave loads, the anchor rope with the shortest stress length begins to be stressed, and due to the telescopic movement of the reset spring, the stress length of the anchor rope is increased. When the stress length of the anchor rope is the same as the second shortest anchor rope, the anchor rope with the second shortest stress length begins to be stressed; in this way, it gradually develops, and finally reaches a state where all anchor ropes are evenly stressed, and at this time the deformation amount of the elastic telescopic device of the anchor rope with the shortest stress length is This solves the stress concentration phenomenon of the anchor rope under the action of wind and wave loads.

[0010] Preferably, the connection assembly also includes a fifth connecting ring; the fifth connecting ring is provided at one end of the anchor rope, and when in use, the anchor rope and the fixed structure can be connected and fixed through the fifth connecting ring.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with traditional floating photovoltaic power stations, due to geological terrain and construction quality issues, the anchoring points are relatively non-uniform in spatial position, while the length of the rope and the connection point between the rope and the floating body are fixed, resulting in inconsistent force length of the rope of the anchoring system. When the floating body is subjected to wind and wave loads, stress concentration of the rope occurs, causing the rope to break and the anchoring system to fail. This device connects an elastic telescopic device in series, and uses the telescopic deformation of the elastic telescopic device to compensate for the inconsistent force length of the rope caused by construction or other factors, thereby solving the stress concentration phenomenon of the rope under wind and wave loads;

[0014] 2. The telescopic rod is driven to telescope by the expansion and contraction of the reset spring, so as to adjust the position of the third connecting ring. When the device is subjected to wind and wave loads, the shortest anchor rope on the device begins to be stressed, and the anchor rope is forced to drive the reset spring to telescope. The stress length of the anchor rope is increased by the expansion and contraction deformation of the reset spring, so as to compensate for the inconsistency of the anchor rope stress length caused by construction or other factors. It is assumed that there are n anchor ropes, the total tension borne by all anchor ropes under the action of wind and wave loads is F, the maximum stress length difference between the anchor ropes is Δx, and the elastic deformation coefficient of the reset spring is k. When the floating body array is subjected to wind and wave loads, the anchor rope with the shortest stress length begins to be stressed. Due to the expansion and contraction movement of the reset spring, the stress length of the anchor rope is increased. When the stress length of the anchor rope is the same as the second shortest anchor rope, the anchor rope with the second shortest stress length begins to be stressed. In this way, all anchor ropes are gradually developed to a state where all anchor ropes are evenly stressed. At this time, the deformation amount of the elastic expansion and contraction device of the anchor rope with the shortest stress length is This can solve the stress concentration phenomenon of anchor ropes under wind and wave loads;

[0015] 3. Protect the reset spring and telescopic rod with a protective cover to prevent long-term wave erosion from causing severe wear to the elastic structure, and use the telescopic rod to prevent the reset spring from being severely twisted when it is extended or retracted.

The outer side of the telescopic rod 302 is provided with a reset spring 401, and one end of the telescopic rod 302 is provided with a third connecting ring 402. When in use, the reset spring 401 and the telescopic rod 302 are protected by the protective sleeve 301 to prevent long-term wave erosion from causing significant wear to the elastic structure. The telescopic rod 302 is used to prevent the reset spring 401 from being greatly twisted when it is extended and retracted. The telescopic rod 302 is driven to extend and retract by the reset spring 401, thereby adjusting the position of the third connecting ring 402.

[0024] The connection assembly 5 also includes a fourth connection ring 501 and an anchor rope 502; the fourth connection ring 501 is arranged on one side of the third connection ring 402, and the anchor rope 502 is arranged on one side of the fourth connection ring 501. When the device is in use, when the device is subjected to wind and wave loads, the anchor rope 502 with the shortest force on the device begins to be stressed, and the anchor rope 502 is forced to drive the reset spring 401 to perform telescopic movement, and the stress length of the anchor rope 502 is increased by the telescopic deformation of the reset spring 401, so as to compensate for the inconsistency of the stress length of the anchor rope 502 caused by construction or other factors; it is assumed that there are n anchor ropes 502, and all anchor ropes 502 are under wind and wave loads. The total tension under the load is F, the maximum stress length difference between the anchor ropes 502 is Δx, and the elastic deformation coefficient of the reset spring 401 is k. When the floating body array 1 is subjected to wind and wave loads, the anchor rope 502 with the shortest stress length begins to be stressed. Due to the telescopic movement of the reset spring 401, the stress length of the anchor rope 502 is increased. When the stress length of the anchor rope 502 is the same as the second shortest anchor rope 502, the second shortest anchor rope 502 begins to be stressed; gradually develop in this way, and finally reach a state where all anchor ropes 502 are evenly stressed.

[0025] During operation, firstly, the position of the second connecting ring 202 is fixed by nesting the second connecting ring 202 and the first connecting ring 201 , and then the position of the telescopic rod 302 is fixed by the protective cover 301 .

[0026] After the protective cover 301 is fixed, the fifth connecting ring 503 and the sixth connecting ring 601 are nested and connected to connect the anchor rope 502 and the anchor foundation 602;

[0027] After the anchor rope 502 and the anchor foundation 602 are connected, the telescopic rod 302 is telescopically moved by the expansion and contraction of the reset spring 401, thereby adjusting the position of the third connecting ring 402. When the device is subjected to wind and wave loads, the anchor rope 502 with the shortest force on the device begins to be stressed, and the force on the anchor rope 502 drives the reset spring 401 to perform telescopic movement. The expansion and contraction deformation of the reset spring 401 increases the stressed length of the anchor rope 502, thereby compensating for the inconsistent stressed length of the anchor rope 502 caused by construction or other factors.
