Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic modules, and particularly relates to an anti-icing device for floating photovoltaic power plants Background Art

[0002] In recent years, new energy has seen great development, and large-scale construction of solar power stations such as photovoltaic and solar thermal power stations has taken place. Usually, the heliostats of solar power stations adopt a pile-column integrated structure, and the column foundation is the main load-bearing body, which bears various forms of forces such as vertical loads, horizontal loads, and torsional loads. This requires that the column foundation can have the abilities of anti-compression, anti-shear, and anti-torsion. However, in the floating photovoltaic system, when the water surface freezes, the freezing will have a frost heaving effect on the photovoltaic support, and generate extrusion and floating forces on the photovoltaic support, affecting the use effect of the photovoltaic support.

[0003] The utility model patent with the patent number CN219780030U discloses an anti-frost heaving device for a floating photovoltaic column, including a photovoltaic column. A hose is sleeved on one side of the photovoltaic column. Two sleeves are arranged on the outer surface of the hose. The inner parts of the two sleeves are respectively lapped on the outer surface of the hose. Cavities are respectively arranged in the two sleeves. A raised platform is arranged on one side of each of the two cavities. Three through holes are respectively arranged on one side of each of the two cavities. A buffer assembly is arranged in each through hole. When the hose is subjected to an expansion force, the force is transmitted to the spring through the semi-circular plate. Under the cooperation of the spring and the connecting rod, the force received by the hose is buffered. After the buffering is completed, under the action of the spring, the hose rebounds quickly. In this patent, water flow and water vapor will enter the cavity, causing the spring in the cavity to freeze and lose the buffering force. The freezing connects the entire anti-frost heaving device and the support into one body, and the freezing force will still be transmitted to the support, making it difficult to provide protection for the support. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an anti-icing device for floating photovoltaic power plants, which is used to solve the problem that the existing anti-frost heaving device for floating photovoltaic columns is difficult to provide protection for the support against the frost heaving effect in the freezing season.

[0005] To achieve the above purpose, the utility model provides an anti-icing device for floating photovoltaic power plants, including a support, and further including:

An enhancing member is arranged on the outside of the buffer outer sleeve. The support is installed in the through cavity, and the outer wall of the support is in contact with the inner wall of the through cavity.

[0007] The clamping assembly includes a first clamping sleeve and a second clamping sleeve arranged outside the buffer inner sleeve, and a connecting piece arranged on the first clamping sleeve; a locking piece is arranged on the connecting piece; under the action of an external force, the locking piece drives the connecting piece passing through the second clamping sleeve to move, so that the first clamping sleeve and the second clamping sleeve move towards each other to clamp the buffer outer sleeve.

[0008] As a further improvement of the present utility model, the reinforcing piece includes a reinforcing sleeve; the friction piece includes an internal friction ring respectively arranged on the inner wall of the reinforcing sleeve and an external friction ring arranged on the outer wall of the reinforcing sleeve; a first groove for clamping with the internal friction ring is arranged on the outer wall of the buffer inner sleeve; a second groove for clamping with the external friction ring is arranged on the outside of the buffer outer sleeve.

[0009] As a further improvement of the present utility model, a cavity is arranged in the inner wall of the buffer outer sleeve; a grid-shaped support piece is arranged in the cavity.

[0010] As a further improvement of the present utility model, a reinforcing friction ring is arranged on the outer wall of the reinforcing member; a third groove for cooperating with the reinforcing friction ring is arranged on the outer wall of the buffer outer sleeve.

[0011] As a further improvement of the present utility model, connecting holes with opposite axles are respectively arranged on the first clamping sleeve and the second clamping sleeve; the connecting piece passes through the connecting holes and is connected with the locking piece.

[0012] The beneficial effects of the present utility model are reflected in:

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0020] In one embodiment, referring to Figure 1 , a water-based photovoltaic anti-icing device of the present utility model includes a bracket 1, an anti-icing assembly, and a clamping assembly.

[0022] Further, referring to Figure 3 , the reinforcement 3 includes a reinforcement sleeve; the friction members 6 include an inner friction ring 12 respectively provided on the inner wall of the reinforcement sleeve and an outer friction ring 13 provided on the outer wall of the reinforcement sleeve; a first groove 14 for clamping with the inner friction ring 12 is provided on the outer wall of the buffer inner sleeve 2; a second groove 15 for clamping with the outer friction ring 13 is provided on the outside of the buffer outer sleeve 4.

[0023] Preferably, both the buffer inner sleeve 2 and the buffer outer sleeve 4 are made of elastic rubber material. The buffer inner sleeve 2 is a hollow cylinder with both ends open, and the buffer outer sleeve 4 is a frustum with a hollow interior.

[0024] Preferably, the reinforcing sleeve is made of metal and is a hollow cylinder with openings at both ends.

[0025] Preferably, the inner friction rings 12 and the outer friction rings 13 are respectively arranged on the reinforcing sleeve at intervals.

[0026] Preferably, one end of the buffer inner sleeve 2 away from the water surface extends beyond the end of the reinforcing member 3.

[0027] In the above setting, the buffer inner sleeve 2 is located inside the reinforcing sleeve and is clamped with the inner friction ring 12 through the first groove 14. By arranging multiple groups of inner friction rings 12, the connection stability between the buffer inner sleeve 2 and the reinforcing sleeve can be enhanced; the reinforcing sleeve is located in the buffer outer sleeve 4 and is clamped with the outer friction ring 13 through the second groove 15. By arranging multiple groups of outer friction rings 13, the connection stability between the buffer outer sleeve 4 and the reinforcing sleeve can be enhanced.

[0028] Further, referring to Figure 3 , a cavity 16 is provided in the inner wall of the buffer outer sleeve 4, and a grid-shaped support member 17 is provided in the cavity 16.

[0029] Preferably, the support member 17 is made of elastic rubber material.

[0030] Further, referring to Figure 3 , an enhanced friction ring 18 is provided on the outer wall of the reinforcing member 7; a third groove 19 that cooperates with the enhanced friction ring 18 is provided on the outer wall of the buffer outer sleeve 4.

[0031] Preferably, the reinforcing member 7 is a frustum-shaped metal structure.

[0032] Preferably, multiple groups of enhanced friction rings 18 are arranged at intervals.

[0033] In the above setting, the reinforcing member 7 is installed outside the buffer outer sleeve 4 and is clamped with the enhanced friction ring 18 through the third groove 19, thereby increasing the connection stability between the buffer outer sleeve 4 and the reinforcing member 7; when subjected to the force of frost heaving, the force pushes the reinforcing member 7 to move horizontally and upward, and the force is transmitted into the buffer outer sleeve 4 and buffered by the grid-shaped support member 17 for primary energy consumption. The force is transmitted to the reinforcing member 3 and then reaches the buffer inner sleeve 2, and the buffer inner sleeve 2 buffers the force for secondary energy consumption, thereby weakening the influence of frost heaving on the bracket 1.

[0034] Further, referring to Figure 2 , the first clamping sleeve 8 and the second clamping sleeve 9 are respectively provided with connection holes with opposite centers; the connecting member 10 passes through the connection holes and is connected to the locking member 11.

[0035] Preferably, the first clamping sleeve 8 and the second clamping sleeve 9 are formed by dividing a ring into two halves. Ear plates 20 are respectively provided on the first clamping sleeve 8 and the second clamping sleeve 9, and the connecting holes are arranged on the ear plates 20.

[0036] Preferably, the connecting member 10 is a bolt and the locking member 11 is a nut.

[0037] In the above setting, the first clamping sleeve 8 and the second clamping sleeve 9 are respectively located on the outer wall of the end of the buffer inner sleeve 2 that extends beyond the reinforcing member 3. A bolt is used to pass through the connecting hole and connect with the nut, clamping the first clamping sleeve 8 and the second clamping sleeve 9 outside the buffer inner sleeve 2, so that the whole device is stably connected to the bracket 1.

[0038] In this embodiment, after the device is stably connected to the bracket 1 through the first clamping sleeve 8 and the second clamping sleeve 9, the device and the bracket 1 are tightly connected, and it is difficult for water flow and water vapor to enter, so the condition for forming ice is not available, ensuring the normal function of the device. During the freezing period, the force generated by frost heaving pushes the reinforcing member 7 to move horizontally and upward. The force is transmitted into the buffer outer sleeve 4 and buffered by the grid-shaped support member 17 for the first-stage energy consumption. The force is transmitted to the reinforcing member 3 and then reaches the buffer inner sleeve 2, and the buffer inner sleeve 2 buffers the force for the second-stage energy consumption, thereby reducing the impact of frost heaving on the bracket 1.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
