Description

Technical Field

[0001] This disclosure relates to the field of fire protection testing technology for converter valve halls, and in particular to a test model structure and testing equipment for fireproof sealing of converter valve halls. Background Technology

[0002] Since sealing materials are usually used at the bushing openings of converter valve halls, in order to test the fire resistance and explosion resistance performance of the sealing materials, it is generally necessary to conduct a simulated test on the on-site installation to test whether the sealing materials meet the standard fire resistance and explosion resistance requirements, such as the fire resistance test structure for fireproof sealing of converter station valve halls disclosed in Chinese Patent Document No. CN 111636581 A.

[0003] In the traditional fire resistance test structure testing process, since the composite fireproof board is supplied as a whole board, it needs to be cut according to the size to be tested on site. Then, the cut boards are stacked to form a simulation test model structure of the fireproof sealing board structure that conforms to the actual construction site. Then, the simulation test model structure is tested.

[0004] However, the above-mentioned fire resistance test structure has problems: the incoming material size of the composite fireproof board is large, which makes on-site cutting inconvenient and transportation difficult. In particular, there is also the problem of interlocking between composite fireproof boards, which makes on-site cutting even more difficult and affects the test assembly efficiency. In addition, each test requires a separate matching size, which has a low compatibility problem. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a test model structure and its testing equipment for fireproof sealing of a converter valve hall that does not require on-site cutting, is easy to transport, and improves the assembly efficiency and compatibility of the test model structure.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A test model structure for fireproof sealing of a converter valve hall includes a doorway mounting frame and an explosion-proof fireproof plate, wherein the explosion-proof fireproof plate is embedded in the doorway mounting frame.

[0008] The doorway mounting frame includes a main frame, multiple built-in brackets, and at least one recess bracket. The multiple built-in brackets are respectively disposed on the main frame, and at least one recess bracket is disposed on the main frame. The recess bracket is provided with a through area, which is used to accommodate the installation pipe of the converter valve hall. The built-in brackets have an installation area.

[0009] The explosion-proof and fireproof board includes multiple explosion-proof and fireproof sub-boards. Each explosion-proof and fireproof sub-board is detachably installed on the built-in frame and encloses the installation area. Each explosion-proof and fireproof sub-board includes a first fire-resistant and explosion-proof chip, a thermal insulation frame, and a second fire-resistant and explosion-proof chip arranged in sequence. The first fire-resistant and explosion-proof chip, the thermal insulation frame, and the second fire-resistant and explosion-proof chip are all connected to the inner wall of the installation area.

[0010] In one embodiment, a through hole is formed within the through area.

[0011] In one embodiment, the diameter of the through hole is greater than 500 mm.

[0012] In one embodiment, at least two through holes are formed within the through area.

[0013] In one embodiment, the through hole is a round hole or a square hole.

[0014] In one embodiment, the built-in insert is threadedly connected to the main frame.

[0015] In one embodiment, the test model structure includes multiple bolts, the built-in insert has a corresponding mounting hole, the main frame has a corresponding threaded hole, and each bolt passes through the mounting hole and the threaded hole in sequence and is screwed to the inner wall of the threaded hole.

[0016] In one embodiment, the first fireproof and explosion-proof chip and / or the second fireproof and explosion-proof chip comprises a stainless steel composite fireproof and explosion-proof plate, a fireproof and heat-insulating fiber plate, and a high-temperature resistant inorganic fireproof plate stacked sequentially; and / or,

[0017] The thermal insulation frame includes a metal mounting frame and a thermal insulation fiber cotton layer. The metal mounting frame is detachably connected to the built-in frame. The first fireproof and explosion-proof chip and the second fireproof and explosion-proof chip are respectively screwed onto two sides of the metal mounting frame. A receiving cavity is formed inside the metal mounting frame, and the thermal insulation fiber cotton layer is fitted into the receiving cavity; and / or

[0018] The test model structure also includes a fixing frame, which is used to fix the mounting tube.

[0019] A test device for fireproof sealing of converter valve hall, comprising the test model structure for fireproof sealing of converter valve hall as described in any of the above embodiments.

[0020] In one embodiment, the test equipment for fireproof sealing of the converter valve hall further includes an explosion-proof testing component, a fire-resistant testing component, and a test model structure for fireproof sealing of the converter valve hall. The test model structure for fireproof sealing of the converter valve hall is detachably mounted to the test installation area of ​​the explosion-proof testing chamber of the explosion-proof testing component.

[0021] The test model structure for fireproof sealing of the converter valve hall is also used for detachable installation of the test installation area of ​​the fire resistance test furnace of the fire resistance testing component; and / or,

[0022] The dimensions of the test installation area of ​​the fire resistance testing furnace of the fire resistance testing component are ≥5m*5m.

[0023] Compared with the prior art, this disclosure has at least the following advantages:

[0024] 1) Since multiple built-in frames are respectively set on the main frame, and each built-in frame has an installation area, the explosion-proof and fireproof sub-panels are detachably installed on the built-in frames and the installation areas are closed, so as to realize the detachable setting of multiple explosion-proof and fireproof sub-panels and multiple built-in frames, thereby realizing multiple partition settings of the whole plate. This allows the operator to prepare the corresponding explosion-proof and fireproof sub-panels and main frame in advance according to the needs of the on-site test structure and assemble them on-site. This eliminates the traditional process of cutting the whole plate on-site, which not only facilitates transportation but also improves the assembly efficiency of the test model structure and improves the compatibility of the test model structure, that is, it realizes the compatibility of on-site test structures of different sizes.

[0025] 2) Furthermore, since the explosion-proof and fireproof sub-board includes a first fire-resistant and explosion-proof chip, a thermal insulation frame, and a second fire-resistant and explosion-proof chip arranged in sequence, and the first fire-resistant and explosion-proof chip, the thermal insulation frame, and the second fire-resistant and explosion-proof chip are all connected to the inner wall of the installation area, the explosion-proof and fireproof sub-board can be partitioned. This allows the operator to prepare the corresponding first fire-resistant and explosion-proof chip, thermal insulation frame, and second fire-resistant and explosion-proof chip in advance according to the requirements of the on-site test structure. In other words, the operator can replace the first fire-resistant and explosion-proof chip, thermal insulation frame, and second fire-resistant and explosion-proof chip of various materials according to the requirements of the on-site test structure, further improving the compatibility of the test model structure with tests of various materials.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0038] Please refer to 1 to Figure 3 An experimental model structure 10 for fireproof sealing of a converter valve hall, according to one embodiment, includes a doorway mounting frame 100 and an explosion-proof fireproof plate 200. The explosion-proof fireproof plate 200 is embedded in the doorway mounting frame 100. The doorway mounting frame 100 includes a main frame 110, multiple built-in brackets 120, and at least one obstruction bracket 130. The multiple built-in brackets 120 are respectively disposed on the main frame 110, and at least one obstruction bracket 130 is disposed on the main frame 110. The obstruction bracket 130 is provided with a through area 131, which is used to accommodate the installation pipe 400 of the converter valve hall. The built-in brackets 120 have installation areas 121. The explosion-proof fireproof plate 200 includes multiple explosion-proof fireproof sub-plates 201. Each explosion-proof fireproof plate 200 sub-plate is detachably installed on the built-in brackets 120 and closes the installation areas 121. Please refer to the accompanying documentation. Figure 5 The explosion-proof and fireproof sub-board 201 includes a first fireproof and explosion-proof chip 210, a heat insulation frame 220 and a second fireproof and explosion-proof chip 230 arranged in sequence. The first fireproof and explosion-proof chip 210, the heat insulation frame 220 and the second fireproof and explosion-proof chip 230 are all connected to the inner wall of the installation area 121.

[0039] It is understood that, since multiple built-in brackets 120 are respectively set on the main frame 110, and each built-in bracket 120 has an installation area 121, the explosion-proof and fireproof sub-plates 200 are detachably installed on the built-in brackets 120 and the installation area 121 is closed, so as to realize the detachable setting of multiple explosion-proof and fireproof sub-plates 200 and multiple built-in brackets 120, thereby realizing multiple partition settings of the whole plate, allowing the operator to prepare the corresponding explosion-proof and fireproof sub-plates 200 and the main frame 110 in advance according to the needs of the on-site test structure and assemble them on-site, eliminating the traditional process of cutting the whole plate on-site. This not only facilitates transportation but also improves the assembly efficiency of the test model structure 10 for fireproof sealing of the converter valve hall and improves the compatibility of the test model structure 10 for fireproof sealing of the converter valve hall, that is, realizing the compatibility of on-site test structures of different sizes.

[0040] It is also understandable that, since the explosion-proof and fireproof sub-board 201 includes a first fireproof and explosion-proof chip 210, a thermal insulation frame 220, and a second fireproof and explosion-proof chip 230 arranged in sequence, and the first fireproof and explosion-proof chip 210, the thermal insulation frame 220, and the second fireproof and explosion-proof chip 230 are all connected to the inner wall of the installation area 121, the explosion-proof and fireproof sub-board 201 is partitioned, allowing the operator to prepare the corresponding first fireproof and explosion-proof chip 210, thermal insulation frame 220, and second fireproof and explosion-proof chip 230 in advance according to the requirements of the on-site test structure. That is, the operator can replace the first fireproof and explosion-proof chip 210, thermal insulation frame 220, and second fireproof and explosion-proof chip 230 of various materials according to the requirements of the on-site test structure, further improving the compatibility of the test model structure 10 for fireproof sealing of the converter valve hall with tests of various materials.

[0041] In some other embodiments, a through hole is formed in the through area 131. In other embodiments, at least two through holes are formed in the through area 131 to better adapt to the test model structure 10 for fireproof sealing of converter valve halls under various application scenarios, thereby improving the compatibility of the test model structure 10 for fireproof sealing of converter valve halls.

[0042] Specifically, in some application scenarios of the test model structure 10 for fireproof sealing of converter valve halls, the operator can set the specific structure of the through hole, such as round hole or square hole, according to the requirements of various application scenarios of fireproof sealing of converter valve halls, so as to better adapt to the test model structure 10 for fireproof sealing of converter valve halls under various application scenarios, thereby ensuring the authenticity of the simulation of the test model structure 10 for fireproof sealing of converter valve halls under different application scenarios.

[0043] Specifically, in one embodiment, the diameter of the through hole is greater than 500 mm, and the thickness of the mounting tube 400 is 20 mm. Further, in one embodiment, the diameter of the through hole is 1000 mm, and the thickness of the mounting tube 400 is 20 mm. Of course, the operator may also set the corresponding size of the through hole and the mounting tube 400 according to the specific application scenario of fireproof sealing of the converter valve hall; therefore, no specific limitations are made in this disclosure.

[0044] In one embodiment, the built-in insert 120 is threadedly connected to the main frame 110 to enable the built-in insert 120 and the main frame 110 to be detachable, facilitating disassembly and assembly by the operator.

[0045] Specifically, such as Figure 1 As shown, in one embodiment, the test model structure 10 for fireproof sealing of the converter valve hall includes a plurality of bolts 300, the built-in bracket 120 is provided with a mounting hole, and the main frame 110 is provided with a threaded hole. Each bolt 300 passes through the mounting hole and the threaded hole in sequence and is screwed to the inner wall of the threaded hole to realize the threaded connection between the built-in bracket 120 and the main frame 110.

[0046] like Figure 3 and Figure 4 As shown, in one embodiment, the first fireproof and explosion-proof chip 210 and / or the second fireproof and explosion-proof chip 230 include a stainless steel composite fireproof and explosion-proof plate 211, a fireproof and heat-insulating fiber plate 212 and a high-temperature resistant inorganic fireproof plate 213 stacked in sequence to achieve the fireproof and explosion-proof performance of the explosion-proof sub-plate 201.

[0047] Specifically, such as Figure 6As shown, in one embodiment, the thermal insulation frame 220 includes a metal mounting frame 221 and a thermal insulation fiber cotton layer 222. The metal mounting frame 221 is detachably connected to the built-in frame 120, allowing for detachable installation and disassembly by the operator. The first fireproof and explosion-proof chip 210 and the second fireproof and explosion-proof chip 230 are respectively screwed onto the two sides of the metal mounting frame 221, thus achieving a detachable arrangement between the first fireproof and explosion-proof chip 210, the second fireproof and explosion-proof chip 230, and the metal mounting frame 221, facilitating operator access. This allows for combined testing of the first fireproof and explosion-proof chip 210, the second fireproof and explosion-proof chip 230, and the thermal insulation frame 220 made of different materials, thereby improving the adaptability of the test model structure 10 for fireproof sealing of the converter valve hall. The metal mounting frame 221 has a receiving cavity, and the thermal insulation fiber cotton layer 222 is fitted into the receiving cavity, making full use of the space inside the mounting frame. This allows the thermal insulation fiber cotton layer 222 to be connected with the metal mounting frame 221 to form a relatively stable thermal insulation frame 220, which not only improves the compactness of the explosion-proof and fireproof sub-plate 201 structure but also ensures the structural stability of the explosion-proof and fireproof sub-plate 201.

[0048] Specifically, in one embodiment, the stainless steel composite fireproof and explosion-proof board 211 includes stainless steel plates and magnesium sulfate fireproof boards stacked in sequence; the stainless steel composite fiber cement includes stainless steel perforated plates and fiber cement boards stacked in sequence; the fireproof and heat-insulating fiber board 212 includes any one of aluminum silicate fiber board and ceramic fiber board; and the high-temperature resistant inorganic fireproof board 213 includes any one of low-density gray silica base board, magnesium sulfate fireproof board and glass magnesium fireproof board. This facilitates the preparation of a lighter and thinner first fireproof and explosion-proof chip 210 and second fireproof and explosion-proof chip 230, thereby reducing the assembly difficulty of the test model structure 10 for fireproof sealing of the converter valve hall.

[0049] like Figure 5 As shown, in one embodiment, the test model structure 10 for fireproof sealing of the converter valve hall further includes a fixing frame 500, which is used to fix the mounting pipe 400.

[0050] This disclosure also provides a test device for fireproof sealing of a converter valve hall, including the test model structure 10 for fireproof sealing of a converter valve hall as described in any of the above embodiments. The test device also includes an explosion-proof testing component. Before conducting a fireproof test on the test model structure 10 for fireproof sealing of the converter valve hall, the explosion-proof testing component is used to conduct an explosion-proof test on the test model structure 10 for fireproof sealing of the converter valve hall. Then, a test fire source is used to conduct a fireproof test on the test model structure 10 for fireproof sealing of the converter valve hall, thereby simulating the fireproof and explosion-proof performance of the fireproof sealing of the converter valve hall.

[0051] In one embodiment, the testing equipment for fireproof sealing of the converter valve hall further includes an explosion-proof testing component, a fire-resistant testing component, and a test model structure 10 for fireproof sealing of the converter valve hall. The test model structure 10 is detachably connected to the test installation area of ​​the explosion-proof testing chamber of the explosion-proof testing component, facilitating the operator's disassembly and assembly of the test model structure 10 to perform explosion-proof testing on the test model structure 10. Furthermore, since the test model structure 10 is also detachably connected to the test installation area of ​​the fire-resistant testing furnace of the fire-resistant testing component, facilitating the operator's disassembly and assembly of the test model structure 10, it allows for fire-resistant testing of the test model structure 10. This ensures that the same test model structure 10 for fireproof sealing of the converter valve hall is tested for explosion-proof performance first and then for fire-resistant performance, meeting the relevant standard requirements for simulated testing of fireproof sealing materials.

[0052] In one embodiment, the test installation area of ​​the fire resistance testing furnace of the fire resistance testing component has a size of ≥5m*5m to meet the requirements of relevant standards such as GB 9978 / ISO 834 / EN1363-1, so as to ensure the authenticity and effectiveness of the simulation test of the test model structure 10 for fireproof sealing of the anti-conversion valve hall.

[0053] In one embodiment, the test installation area of ​​the fire resistance test furnace of the fire resistance testing component is 5m*5m in size, and the test model structure 10 of the fireproof sealing of the converter valve hall is 5m*5m in size, so as to ensure that the test model structure 10 of the fireproof sealing of the converter valve hall with the smallest size can meet the authenticity and effectiveness of the simulation test, thereby saving the cost of the simulation test.

[0054] Compared with the prior art, this disclosure has at least the following advantages:

[0055] 1) Since multiple built-in brackets 120 are respectively set on the main frame 110, and each built-in bracket 120 has an installation area 121, the explosion-proof and fireproof sub-plates 200 are detachably installed on the built-in brackets 120 and the installation area 121 is closed, so as to realize the detachable setting of multiple explosion-proof and fireproof sub-plates 200 and multiple built-in brackets 120, thereby realizing multiple partition settings of the whole plate, so that the operator can prepare the corresponding explosion-proof and fireproof sub-plates 200 and the main frame 110 in advance according to the needs of the on-site test structure and assemble them on-site, eliminating the traditional process of cutting the whole plate on-site. This not only facilitates transportation, but also improves the assembly efficiency of the test model structure 10 for fireproof sealing of the converter valve hall, and improves the compatibility of the test model structure 10 for fireproof sealing of the converter valve hall, that is, realizing the compatibility of on-site test structures of different sizes.

[0056] 2) Furthermore, since the explosion-proof and fireproof sub-plate 201 includes a first fireproof and explosion-proof chip 210, a thermal insulation frame 220, and a second fireproof and explosion-proof chip 230 arranged in sequence, and the first fireproof and explosion-proof chip 210, the thermal insulation frame 220, and the second fireproof and explosion-proof chip 230 are all connected to the inner wall of the installation area 121, the explosion-proof and fireproof sub-plate 201 is partitioned, allowing the operator to prepare the corresponding first fireproof and explosion-proof chip 210, thermal insulation frame 220, and second fireproof and explosion-proof chip 230 in advance according to the requirements of the on-site test structure. That is, the operator can replace the first fireproof and explosion-proof chip 210, thermal insulation frame 220, and second fireproof and explosion-proof chip 230 of various materials according to the requirements of the on-site test structure, further improving the compatibility of the test model structure 10 for fireproof sealing of the converter valve hall with tests of various materials.

[0057] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
