Description

Technical Field

[0001] This utility model relates to the technical field of direct air cooling, and in particular to a duct connection device for a direct air cooling system based on a concrete support beam. Background Technology

[0002] Compared to traditional thermal (coal-fired) power generation technology, concentrated solar power (CSP) is a synchronous power generation technology that utilizes green, clean, and low-carbon energy. While meeting the original intention of the base construction, it has a wider and faster power regulation capability. At the same time, CSP and traditional thermal (coal-fired) power generation have roughly similar working principles and basic electrical properties, both requiring the configuration of a direct air-cooling system. The air-cooling platform in CSP projects typically has two structural forms: one is a pure steel structure with steel columns and steel diagonal braces, where the octagonal beam supporting the air duct is a steel beam. During on-site installation, the air duct is connected to the supporting steel beam (with pre-drilled bolt holes) via a connecting plate (with pre-drilled bolt holes) on the top of the large blade plate using high-strength bolts, which is convenient and quick; the other is a concrete frame structure.

[0003] The existing octagonal beams connecting the concrete frame structure and the ventilation duct are concrete beams, which cannot be directly bolted together. In order to meet the needs of later maintenance and disassembly, the ventilation duct connecting plate cannot be directly welded to the embedded parts of the concrete beam. At the same time, the construction precision of the concrete structure is much lower than that of the steel structure, which greatly increases the installation difficulty. Summary of the Invention

[0004] To address the aforementioned problems with existing connections between concrete octagonal beams and air ducts, this paper aims to provide a direct air-cooling system air duct connection device based on concrete support beams that facilitates maintenance and reduces installation difficulty.

[0005] The specific technical solution is as follows:

[0006] A direct air-cooled system based on a concrete support beam duct connection device includes:

[0007] Embedded parts, which are cast to the side of the concrete support beam;

[0008] A steel structure bracket, wherein the steel structure bracket is fixed on the embedded part, and the top of the steel structure bracket has at least one first mounting hole;

[0009] An adjustable cover plate is provided on the top of the steel structure bracket, and one end of the adjustable cover plate has at least one adjustment hole, which is a waist-shaped hole;

[0010] A connecting plate is provided, the bottom of which is connected to a large blade plate of the air duct. The connecting plate has at least one second mounting hole, and the other end of the adjustable cover plate has at least one third mounting hole. High-strength bolts are connected between the third mounting hole and the second mounting hole, and between the adjustment hole and the first mounting hole.

[0011] As a further improvement and optimization of this solution, the steel structure bracket is fixed to the embedded part by welding.

[0012] As a further improvement and optimization of this solution, the steel structure bracket is characterized in that it includes:

[0013] Two end plates are arranged vertically and are both rectangular plate structures. The first mounting hole is located on the upper end plate. Each end plate is welded to the embedded part.

[0014] Two first support plates are connected in parallel between the two end plates, and each first support plate is distributed along the width direction of the end plate.

[0015] As a further improvement and optimization of this solution, it is characterized by including two second support plates, which are connected between the two end plates and located on opposite sides of the two first support plates, and the two second support plates are perpendicularly connected to the two first support plates respectively.

[0016] As a further improvement and optimization of this solution, the adjustable cover plate has an ear plate at its top, and the ear plate is provided with a lifting hole.

[0017] As a further improvement and optimization of this solution, the top opening of the adjustment hole is further provided with a pad, and the pad has at least one fourth mounting hole coaxially arranged with the first mounting hole.

[0018] As a further improvement and optimization of this solution, the ear plate and the adjustable cover plate are integrated into one structure.

[0019] As a further improvement and optimization of this solution, the major axis of the adjustment hole is parallel to the length direction of the end plate.

[0020] The positive effects of the above technical solution compared with the existing technology are:

[0021] This utility model enables on-site adjustment during connection by setting adjustment holes on the adjustable cover plate, effectively solving the problem of inconvenient installation caused by the construction precision of concrete structures. At the same time, when maintenance is required, it is only necessary to remove the high-strength bolts between the adjustable cover plate and the steel structure bracket, as well as the high-strength bolts between the adjustable cover plate and the connecting plate, and remove the adjustable cover plate to lift the entire duct out for maintenance, which is convenient and quick.

Figure 1-4 The diagram illustrates a preferred embodiment of a direct air-cooled system with a duct connection device based on a concrete support beam. The device includes an embedded part 2, a steel bracket 3, an adjustable cover plate 5, and a connecting plate 6. The embedded part 2 is cast onto the side of the concrete support beam 1.

High-strength bolts connect the third mounting hole 61 to the second mounting hole 52, and the adjustment hole 53 to the first mounting hole 31.

[0031] Specifically, when pouring the concrete support beam structure on site, the embedded part 2 needs to be placed in a designated position on the side of the ventilation duct support beam in advance, so that it can be poured into a whole with the concrete frame structure.

[0032] In this embodiment, when installing the air duct, the steel structure bracket 3 is first welded to the embedded part 2.

[0034] In this embodiment, by setting adjustment holes 53 on the adjustable cover plate 5, the on-site adjustment function during connection is realized, which effectively solves the problem of inconvenient installation caused by the construction precision of concrete structures. At the same time, when maintenance is required, it is only necessary to remove the high-strength bolts between the adjustable cover plate 5 and the steel structure bracket 3 and the high-strength bolts between the adjustable cover plate 5 and the connecting plate, and remove the adjustable cover plate 5 to lift the entire air duct out for maintenance, which is convenient and quick.

Each end plate 32 is welded to the embedded part 2. The two first support plates 33 are connected in parallel between the two end plates 32, and each first support plate 33 is distributed along the width direction of the end plate 32.

[0037] Furthermore, as a preferred embodiment, in order to further improve the strength of the steel structure bracket 3, it also includes two second support plates 34.
