Description

Technical Field

[0001] The utility model relates to the technical field of assembling an integrated inverter machine for a water tank, in particular to a concrete platform pre-assembled system for an integrated inverter machine for a water tank. Background Art

[0002] As large-scale onshore photovoltaic projects require a large amount of land area and land resources, and as the photovoltaic land use policy has become increasingly tightened in the past two years, more and more power station developers and component manufacturers have turned their attention to offshore photovoltaic projects. Under the same lighting conditions, due to the advantages of open sea surface, no obstructions, long sunshine time, and high radiation, offshore photovoltaic projects have higher light utilization efficiency. Compared with onshore photovoltaic power stations, offshore photovoltaic power stations have significantly increased their power generation.

[0003] Given that water and offshore photovoltaics are still in their infancy, there is a relative lack of standards in terms of engineering design, construction, operation and maintenance, and there is no successful experience to draw on. In the actual process of advancement, the difficulty of project implementation is much greater than expected. In particular, the construction of offshore photovoltaic projects, due to the influence of the complex marine environment, requires, on the one hand, to reduce the difficulty of construction and the difficulty and cost of operation and maintenance, while taking into account efficiency and energy saving; on the other hand, it also requires breakthroughs in key technical directions such as wave resistance, sea ice resistance, cold wave resistance, and salt spray resistance. It not only ensures that the offshore photovoltaic project platform under construction has good corrosion resistance and can effectively maintain stability and reliability after frequent impacts of waves, floating ice, etc., but also meets the design and construction requirements in terms of cold wave resistance, sea fog and corrosion resistance. Utility Model Content

[0004] The utility model provides a pre-assembled system of a water tank inverter integrated machine concrete platform, which adopts a concrete pre-assembled construction scheme, which can not only solve the problems of great construction difficulty, high cost and slow construction progress caused by pouring a large amount of concrete on site, but also ensure that the built concrete platform has good stability and reliability. In addition, compared with the steel structure platform, the concrete platform built based on this patent scheme can be more durable and reliable in humid and corrosive environments such as water surfaces, tidal flats, and swamps, and the operation and maintenance cost is lower.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a pre-assembled system of a concrete platform of an above-water tank inverter integrated machine, comprising a pile foundation assembly, a support assembly and a plurality of operation and maintenance platform plates.

[0006] The pile foundation assembly comprises a plurality of hollow square piles, a plurality of transverse connecting rods and a plurality of longitudinal connecting rods. The hollow square piles are arranged in two rows facing each other, and the plurality of hollow square piles in each row are evenly arranged in a longitudinal direction.

[0007] The transverse connecting rod is connected between two hollow square piles that are opposite to each other in the front and rear, and the longitudinal connecting rod is connected between two hollow square piles that are adjacent to each other in the left and right.

[0008] The support assembly includes at least one pair of support beams arranged front and back oppositely, and a support frame fixed to the periphery of the support beams. The inner side surface of the support frame is formed with a straight groove in a U shape with the notch facing the front side or the rear side.

[0009] At the lower part of the support beam, a plurality of piles are formed along the longitudinal direction and can be matched with the upper ends of the hollow square piles in each row. The piles can be inserted into the upper ports of the hollow square piles. A plurality of prefabricated threaded holes are arranged on the support beam and are distributed alternately in the longitudinal direction.

[0010] A plurality of connecting rods extending transversely are arranged between the two supporting beams and are distributed alternately in the longitudinal direction, so that the supporting assembly is formed into a frame beam structure.

[0011] One end of the operation and maintenance platform plate is inserted into the U-shaped groove on the support frame.

[0012] On the operation and maintenance platform plate, an assembly through hole corresponding to the prefabricated threaded hole is provided near the other end thereof, and a connecting stud is arranged between the prefabricated threaded hole and the assembly through hole to fix the other end of the operation and maintenance platform plate to the support beam.

[0013] After the pile foundation assembly is processed in a workshop or factory, it is necessary to carry out epoxy coating anti-corrosion construction coating treatment on the entire outer surface and inner surface of the pile foundation assembly, and the epoxy anti-corrosion coating is coated on the surface of the pile foundation assembly.

[0014] After the support assembly or the concrete platform formed by the support assembly is assembled with the pile foundation assembly and the relative positions between the two are adjusted, concrete is injected into the cavity of the hollow square pile to connect the hollow square pile with the pile column as a whole. After the concrete injected into the hollow square pile is set, the pile foundation assembly can be connected with the support assembly to form a solid whole.

[0015] Optionally, a plurality of embedded parts which are longitudinally spaced apart are provided on the support beam, and a longitudinal interval is maintained between the set position of the prefabricated threaded hole and the fixed position of the embedded part.

[0016] The embedded part extends downward and forms a pair of arm plates facing each other front and back, and through holes for bolts to pass through are arranged at the ends of the pair of arm plates. Nuts are matched at the ends of the screw rods of the bolts, and the ends of the pair of arm plates can be connected into one piece by means of the bolts and the nuts. The longitudinal connecting rod is inserted between the pair of arm plates, and the bolts are relatively located below the longitudinal connecting rods.

[0017] By means of the matching structure between the embedded parts and the longitudinal connecting rod, the support assembly can be fixedly connected to the upper part of the pile foundation assembly to complete the pre-assembly. After adjusting the position of the support assembly relative to the pile foundation assembly, tightening the bolts and nuts provided at the lower part of the arm plate can establish a relatively fixed connection structure between the pile foundation assembly and the support assembly. Then, concrete is injected into the cavity of the hollow square pile to connect the hollow square pile with the pile column as a whole. After the concrete injected into the hollow square pile is set, the pile foundation assembly can be connected with the support assembly to form a whole.

[0018] After the connection and assembly of the support assembly is completed in the workshop or factory, the support assembly can be poured with concrete to form a concrete platform. The prefabricated threaded holes and the lower part of the embedded parts should be prevented from being blocked or wrapped inside by concrete. The surface of the support assembly exposed outside the concrete needs to be coated with epoxy coating for anti-corrosion construction.

[0019] Optionally, the pile foundation assembly further includes a plurality of tie rods and pin shaft portions corresponding to and matching the ends of the tie rods.

[0020] The pull rods are arranged in pairs and in an X-shaped cross arrangement. One end of the pin rod of the pin shaft portion is formed as a pivot end, and the other end is formed as an external thread section and matched with a nut.

[0021] Four pin shafts are arranged on the upper part of the hollow square pile, so that the pin shaft axes of two of the pin shafts extend in the front-rear direction and are arranged alternately up and down, and the pin shaft axes of the other two pin shafts extend in the longitudinal direction and are arranged alternately up and down.

[0022] A pair of pull rods are arranged between two front and rear opposite hollow square piles, and the two ends of the pull rods are respectively hingedly matched with the pivot ends of two transversely arranged pin shaft parts which are arranged obliquely upward and obliquely downward on the upper parts of the two hollow square piles.

[0023] Starting from one end in the longitudinal direction, a pair of pull rods are arranged between each two adjacent hollow square piles, and the two ends of the pull rods are respectively hingedly matched with the pivot ends of two longitudinally arranged pin shaft parts which are arranged obliquely upward and obliquely downward on the upper parts of the two hollow square piles.

[0024] Screwing the nut on the external threaded section of the pin rod can pull the end of the pull rod hinged on the pivot end in the horizontal or longitudinal direction to level and stabilize the upper end surface of the hollow square pile, and can form prestress between the two hollow square piles, which helps to enhance the impact resistance of the pile foundation assembly and promote the stability and reliability of the pile foundation.

[0025] Optionally, the longitudinal link includes a first longitudinal link and a second longitudinal link.

[0026] The two ends of the second longitudinal connecting rod are hinged on two pivot ends corresponding to and matching the lower ends of a pair of pull rods arranged on two hollow square piles.

[0027] Two ends of the first longitudinal connecting rod are connected between two of the hollow square piles located between two adjacent second longitudinal connecting rods.

[0028] The beneficial effects of the utility model are as follows: the concrete platform pre-assembled system involved in the patent scheme is a concrete platform that is constructed in a pre-assembled manner to fix and support the water tank inverter integrated machine. It can not only solve the problems of difficulty, high cost and slow construction progress caused by pouring a large amount of concrete on site, but also the built concrete platform is more durable and reliable than the steel structure platform in humid and corrosive environments such as water surfaces, mudflats and swamps, and the operation and maintenance cost is lower. In addition, this pre-assembled system of the concrete platform of the water tank inverter integrated machine is conducive to the standardization, modularization, industrialization and mechanization of offshore photovoltaic construction projects, and can provide an efficient, controllable, standard, energy-saving, environmentally friendly and economical construction model for the construction of water photovoltaic, offshore photovoltaic and other scenes. This model has a certain foundation significance in engineering technology, construction, operation and maintenance, cost reduction and efficiency improvement, and can play a significant role in promoting the commercialization and scale-up of pile-based fixed water / offshore photovoltaic project construction.

[0044] At the lower part of the support beam 21, a plurality of piles 211 are formed along the longitudinal direction and can be matched with the upper ends of the hollow square piles 11 in each row. The piles 211 can be inserted into the upper ports of the hollow square piles 11. A plurality of prefabricated threaded holes 212 are arranged in a longitudinally spaced manner on the support beam 21. At the same time, a plurality of embedded parts 213 are arranged in a longitudinally spaced manner on the support beam 21, and a longitudinal interval is maintained between the set positions of the prefabricated threaded holes 212 and the fixed positions of the embedded parts 213.

[0045] A plurality of connecting rods (not shown in the figure) extending transversely are provided between the two support beams 21 and are distributed alternately in the longitudinal direction, so that the support assembly forms a frame beam structure.

[0046] One end of the operation and maintenance platform plate 30 is inserted into the U-shaped groove on the support frame 22 .
