Description

Technical Field

[0001] The invention relates to the technical field of casing plugging on converter transformer valve side of a converter station, and in particular to a stainless steel surface aluminum silicate composite plate combined assembly structure. Background Art

[0002] The valve hall of the converter station is a closed building for placing converter valves. The converter transformer bushing design needs to be installed through the wall. When installing the converter transformer bushing, a fireproof structure needs to be set between the converter transformer bushing and the firewall to meet the fire prevention requirements. The sealing structure of each connection in the fireproof structure must meet the requirements of fire prevention, smoke isolation and waterproofing in daily operation and after a fire occurs. The fireproof board is usually composed of multiple boards.

[0003] In the prior art, a fireproof and explosion-proof structure for sealing the valve side bushing of a converter transformer in a converter station with application number 201910441087.9 is disclosed, in which the converter transformer bushing is installed in the converter transformer bushing installation hole, and an aluminum silicate needle-punched blanket layer is filled between the wall of the converter transformer bushing installation hole and the outer wall of the converter transformer bushing; the fireproof and explosion-proof panel includes a first metal surface structure rock wool composite panel, a second metal surface structure rock wool composite panel and a non-magnetic stainless steel impact-resistant panel.

[0004] The above patent has achieved fireproof and explosion-proof effects to a certain extent, but the fireproof board is composed of two layers of metal surface structure rock wool composite board, and the temperature resistance is not high enough. Since the temperature resistance of the stainless steel aluminum silicate composite board is higher, some will use a combination of stainless steel surface aluminum silicate composite board and metal surface structure rock wool composite board to withstand and block higher temperatures; due to the large area of ​​fireproof blocking, usually according to actual conditions, multiple stainless steel surface aluminum silicate composite boards are assembled as a whole for use, and the assembly includes longitudinal assembly and transverse assembly. The longitudinal assembly forms multiple vertical joints, the sealing effect at the joints is poor, it is easy to deform at high temperature, and the overall fireproof performance is poor;

[0005] At the same time, if attached Figure 1 As shown, in the prior art, when a converter transformer bushing installation hole is opened on a stainless steel surface aluminum silicate composite plate, if the converter transformer bushing installation hole occupies a large area of ​​the stainless steel surface aluminum silicate composite plate, the stainless steel surface aluminum silicate composite plate after the converter transformer bushing installation hole is opened is divided into two left and right pieces by the converter transformer bushing installation hole, and the width of the connection between the left and right pieces becomes narrower and the area is smaller, resulting in a decrease in the overall strength of the stainless steel surface aluminum silicate composite plate. In addition, more than one converter transformer bushing installation hole is usually provided on the stainless steel surface aluminum silicate composite plate, and the overall strength of the stainless steel surface aluminum silicate composite plate is more affected. In order to enhance the overall strength, the residual plate after the converter transformer bushing installation hole is opened needs to be strengthened, which increases the process and reduces the installation efficiency. Therefore, it is necessary to design a stainless steel surface aluminum silicate composite plate combined assembly structure to solve the above-mentioned problems, so as to avoid a significant decrease in the overall strength of the stainless steel surface aluminum silicate composite plate. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a stainless steel surface aluminum silicate composite plate combined assembly structure, which can ensure the sealing of the stainless steel surface aluminum silicate composite plate, the sealing effect at the joints is good, the overall fire resistance is good, and the converter transformer bushing installation holes are reasonably opened on multiple stainless steel surface aluminum silicate composite plates to ensure the overall strength of the stainless steel surface aluminum silicate composite plates.

[0007] In order to solve the above technical problems, the technical solution of the present invention is as follows: comprising a plurality of stainless steel surface aluminum silicate composite plates, the stainless steel surface aluminum silicate composite plates are horizontally assembled, the horizontal joints formed when the stainless steel surface aluminum silicate composite plates are assembled are densely filled with aluminum silicate fiber blankets, the aluminum silicate fiber blankets are respectively connected to the splicing ends of the stainless steel surface aluminum silicate composite plates, and a magnesium fireproof board is filled between the two aluminum silicate fiber blankets;

[0008] The stainless steel surface aluminum silicate composite plates are fixed by a bayonet structure when spliced, wherein the bayonet structure of one stainless steel surface aluminum silicate composite plate is limited inside the bayonet structure of another stainless steel surface aluminum silicate composite plate;

[0009] The stainless steel surface aluminum silicate composite plate is provided with a converter transformer bushing mounting hole, which is formed by opening holes on a plurality of stainless steel surface aluminum silicate composite plates and piecing together the holes, and the converter transformer bushing mounting hole is located on the stainless steel surface aluminum silicate composite plate at the following position: the middle portion of the converter transformer bushing mounting hole directly passes through the stainless steel surface aluminum silicate composite plate as a whole to divide the stainless steel surface aluminum silicate composite plate into two disconnected parts, and the upper and lower ends of the converter transformer bushing mounting hole are provided on different stainless steel surface aluminum silicate composite plates, and the height corresponding to this portion of the opening on the stainless steel surface aluminum silicate composite plate is less than half of the overall width of the stainless steel surface aluminum silicate composite plate.

[0010] Furthermore, the stainless steel surface outside the stainless steel surface aluminum silicate composite plate extends with a bayonet bent inwardly, the bayonet is integrally arranged with the stainless steel surface, the aluminum silicate fiber blanket is connected to a stainless steel plate on one side close to the stainless steel surface aluminum silicate composite plate, and bent clamping plates extend from both ends of the stainless steel plate, and the clamping plates are clamped and fixed with the bayonet;

[0011] Among them, the bayonet structure of one stainless steel surface aluminum silicate composite plate is on the extension line of the stainless steel surface outside the stainless steel surface aluminum silicate composite plate, and the bayonet structure of another stainless steel surface aluminum silicate composite plate is connected to the stainless steel surface outside the stainless steel surface aluminum silicate composite plate through an inwardly inclined arc segment. The bayonet structure connected by the arc segment is clamped in the inside of the bayonet structure arranged on the extension line of the stainless steel surface, and the two bayonet structures are filled with an aluminum silicate fiber blanket.

[0012] Furthermore, the two layers of aluminum silicate fiber blankets filled between the two stainless steel-surface aluminum silicate composite plates, and the magnesium fireproof board filled between the two aluminum silicate fiber blankets, are both arranged on the inner side of the bayonet structure connected by arc segments.

[0013] After adopting the above structure, the advantages of the present invention are: the original assembly structure in which the area of ​​the stainless steel surface aluminum silicate composite plate is relatively large when the converter transformer bushing installation hole is opened is changed into a combination of two structural forms: a structure in which the stainless steel surface aluminum silicate composite plate is directly divided into two disconnected parts and a structure in which the height of the opening is less than the overall width of the stainless steel surface aluminum silicate composite plate, so that a plurality of openings are combined to form the converter transformer bushing installation hole, ensuring that there is no connection part less than half of the width on the stainless steel surface aluminum silicate composite plate, ensuring the overall strength of the stainless steel surface aluminum silicate composite plate, avoiding the need to strengthen the connection part of a small area, reducing the process, and improving the installation efficiency;

[0014] The stainless steel-faced aluminum silicate composite panels are assembled horizontally, and the horizontal assembly forms horizontal joints. Due to the effect of gravity, the joints are easier to seal. Compared with vertical joints, the high-temperature deformation of the joints is small, and the sealing effect is better. The joints are fixed by a bayonet structure, and the structural strength is better. The joints are filled with aluminum silicate fiber blankets and magnesium fireproof boards, which have better sealing and better overall fireproof performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments can enable technicians in this field to understand the present invention more comprehensively, but the present invention is not limited to the scope of the embodiments.

[0020] This specific implementation adopts the following technical solutions: Figure 2As shown, it includes several stainless steel surface aluminum silicate composite plates 1, and the stainless steel surface aluminum silicate composite plates 1 are horizontally assembled. The horizontal assembly forms a horizontal joint. Due to the effect of gravity, the joint is easier to seal. Compared with the vertical joint, the sealing effect of the joint is better. The horizontal joint formed when the stainless steel surface aluminum silicate composite plates 1 are assembled is densely filled with aluminum silicate fiber blankets 2. The aluminum silicate fiber blankets 2 are respectively connected to the splicing ends of the stainless steel surface aluminum silicate composite plates 1, and a magnesium fireproof board 3 is filled between the two aluminum silicate fiber blankets 2, which has better sealing and better overall fireproof performance.

[0021] When the stainless steel surface aluminum silicate composite plate 1 is spliced, it is fixed by a bayonet structure composed of a clamping plate 22 and a bayonet 12. The stainless steel surface 11 outside the stainless steel surface aluminum silicate composite plate 1 is extended with a bayonet 12 bent inwardly, and the bayonet 12 is integrally arranged with the stainless steel surface 11. The aluminum silicate fiber blanket 2 is connected to a stainless steel plate 21 on one side close to the stainless steel surface aluminum silicate composite plate 1, and bent clamping plates 22 are extended at both ends of the stainless steel plate 21. The clamping plates 22 are fixed by clamping with the bayonet 12. The two stainless steel surface aluminum silicate composite plates 1 spliced ​​to each other are respectively connected to the aluminum silicate fiber blanket 2. When splicing, a magnesium fireproof board 3 is filled between the two aluminum silicate fiber blankets 2;

[0022] In addition, the bayonet structure of one of the assembled stainless steel surface aluminum silicate composite plates 1 is arranged on the extension line of the stainless steel surface 11 outside the stainless steel surface aluminum silicate composite plate 1, and the bayonet structure of the other stainless steel surface aluminum silicate composite plate 1 is connected to the stainless steel surface 11 outside the stainless steel surface aluminum silicate composite plate 1 through an inwardly inclined arc segment 13, and the bayonet structure connected by the arc segment 13 is clamped on the inner side of the bayonet structure arranged on the extension line of the stainless steel surface 11, and the two bayonet structures are filled with an aluminum silicate fiber blanket, and the two aluminum silicate fiber blankets 2 filled between the two stainless steel surface aluminum silicate composite plates 1, and the magnesium fireproof board 3 filled between the two aluminum silicate fiber blankets 2, are all arranged between the bayonet structures connected by the arc segment 13. The two stainless steel surface aluminum silicate composite plates 1 are spliced ​​together through this structure, with high firmness and good sealing of the splicing.

[0023] like Figure 3 As shown, when a converter transformer bushing installation hole 4 is opened on the stainless steel surface aluminum silicate composite plate 1, since the converter transformer bushing is installed obliquely in the converter transformer bushing installation hole 4, the converter transformer bushing installation hole 4 is elliptical. The opening method of the stainless steel surface aluminum silicate composite plate 1 is selected according to the size of the converter transformer bushing installation hole 4:

[0024] When the upper and lower heights of the converter transformer bushing mounting hole 4 are greater than the width of one stainless steel surface aluminum silicate composite plate 1 and less than the width of two stainless steel surface aluminum silicate composite plates 1, the converter transformer bushing mounting hole 4 is opened on three stainless steel surface aluminum silicate composite plates 1, and the openings on the three stainless steel surface aluminum silicate composite plates 1 are combined to form the converter transformer bushing mounting hole 4;

[0025] The middle part of the converter transformer bushing installation hole 4 is directly passed through the whole of the middle stainless steel surface aluminum silicate composite plate 1, and the middle stainless steel surface aluminum silicate composite plate 1 is divided into two disconnected left and right parts, and the left and right parts are respectively spliced ​​with the adjacent stainless steel surface aluminum silicate composite plate 1, and there is no weak part on the stainless steel surface aluminum silicate composite plate 1 after the opening is removed, so as to ensure the overall strength of the stainless steel surface aluminum silicate composite plate 1, and the upper and lower end parts of the converter transformer bushing installation hole 4 are respectively opened on the upper and lower stainless steel surface aluminum silicate composite plates 1, and the heights of the openings on the upper and lower stainless steel surface aluminum silicate composite plates 1 are both less than half of the width of the stainless steel surface aluminum silicate composite plate 1, and there is no weak part on the stainless steel surface aluminum silicate composite plate 1 after the opening is removed, so as to ensure the overall strength of the stainless steel surface aluminum silicate composite plate 1;

[0026] When the upper and lower heights of the converter transformer bushing mounting hole 4 are equal to the widths of the two stainless steel surface aluminum silicate composite plates 1, the converter transformer bushing mounting hole 4 can be directly set on the two stainless steel surface aluminum silicate composite plates 1, and the two stainless steel surface aluminum silicate composite plates 1 are respectively divided into two disconnected left and right parts by the converter transformer bushing mounting hole 4; when the upper and lower heights of the converter transformer bushing mounting hole 4 are greater than the widths of the two stainless steel surface aluminum silicate composite plates 1 and less than the widths of the three stainless steel surface aluminum silicate composite plates 1, there are two stainless steel surface aluminum silicate composite plates 1 in the middle that are divided into left and right parts, and the same as the manner in which the upper and lower heights of the converter transformer bushing mounting hole 4 are greater than the width of one stainless steel surface aluminum silicate composite plate 1 and less than the width of two stainless steel surface aluminum silicate composite plates 1, the heights of the openings on the upper and lower stainless steel surface aluminum silicate composite plates 1 are both less than half the width of the stainless steel surface aluminum silicate composite plate 1.

[0027] By analogy, when the upper and lower heights of the converter transformer bushing mounting hole 4 are integer multiples of the width of the stainless steel surface aluminum silicate composite plate 1, the converter transformer bushing mounting hole 4 is directly opened on an integer multiple number of stainless steel surface aluminum silicate composite plates 1, and each stainless steel surface aluminum silicate composite plate 1 is divided into two disconnected left and right parts by the converter transformer bushing mounting hole 4; when the upper and lower heights of the converter transformer bushing mounting hole 4 are not integer multiples of the width of the stainless steel surface aluminum silicate composite plate 1, the middle part of the stainless steel surface aluminum silicate composite plate 1 is set on multiple stainless steel surface aluminum silicate composite plates 1, and the heights of the openings on the topmost and bottommost stainless steel surface aluminum silicate composite plates 1 are both less than half of the width of the stainless steel surface aluminum silicate composite plate 1.

[0028] The material technical parameters of the stainless steel surface aluminum silicate composite plate are:

[0029]

[0030] The material technical parameters of aluminum silicate fiber blanket are:

[0031]

[0032] In this specific embodiment, according to the above-mentioned opening arrangement method of the converter transformer bushing mounting hole 4 on the stainless steel surface aluminum silicate composite plate 1, there is no weak connection part on the stainless steel surface aluminum silicate composite plate 1 that is less than half the width of the stainless steel surface aluminum silicate composite plate 1 after removing the opening, thereby ensuring the overall strength of the stainless steel surface aluminum silicate composite plate 1, avoiding the need to strengthen the small area of ​​the connection part, reducing the process and improving the installation efficiency.
