Description
Technical Field
[0001] This utility model relates to the field of fire protection devices for nuclear power plants, and in particular to an adjustable fixed structure for preventing hot work sites. Background Technology
[0002] Currently, nuclear power plant sites require fire protection devices to ensure the safe operation of the plant and prevent fires from posing serious threats to equipment, personnel, and the environment. Because nuclear power plant equipment operates at high temperatures and pressures and involves flammable materials, fires can lead to nuclear safety accidents, equipment damage, and personal injury. Fire protection devices not only effectively suppress the spread of fire, protect core equipment, and ensure personnel safety, but also prevent chain reactions, ensure compliance with nuclear safety regulations, and reduce the risk of environmental pollution and nuclear radiation leaks.
[0003] Nuclear power plant sites require the installation of various fire protection devices. These devices are typically combinations of a frame and fire-resistant materials. Due to the extensive and complex network of pipes, lines, and equipment at nuclear power plants, the installation space for these devices is relatively limited and often irregularly shaped, severely restricting construction. Sparks must be eliminated during installation. Operators must first accurately measure the installation space to ensure each location meets requirements and avoids interference with surrounding facilities. After measurement, operators will precisely install the fire protection devices according to the actual conditions, ensuring they function stably and effectively without affecting the normal operation of other equipment.
[0004] Regarding the aforementioned technologies, measurement results vary from person to person and may contain errors. Operators may also make installation errors during the installation process. Furthermore, due to the limited and complex installation space, gaps may exist between adjacent fire protection devices during splicing, preventing the fire protection devices from fitting properly and resulting in poor stability.

The connector is fixedly connected to one side of the connecting plate. The connector and the connecting plate cooperate to form a connecting assembly. Two connecting assemblies are arranged in sequence, with the connecting plates of the two connecting assemblies facing each other.

[0020] Optionally, both the first positioning plate and the second positioning plate are fixedly connected to one side of the connecting plate along its length.
[0021] By adopting the above technical solution, the first positioning plate and the second positioning plate directly drive the two connecting plates to move closer or further apart, further improving the convenience of adjusting the distance between the two connecting plates.
[0022] Optionally, the number of adjusting components can be several groups, with the adjusting components arranged circumferentially along the telescopic cylinder.
[0023] By adopting the above technical solution, multiple sets of adjusting components work together to position the telescopic block and the telescopic cylinder, thereby improving the connection strength between the telescopic block and the telescopic cylinder.

The telescopic block moves the first positioning plate closer to the second positioning plate. The nuts on both sides of the first and second positioning plates cooperate to position the threaded rod, thereby positioning the telescopic block and the telescopic cylinder, which improves the stability of the fire protection device connection.

[0028] The present application will be further described in detail below with reference to all the accompanying drawings.
[0029] This application discloses an adjustable fixing structure for avoiding hot work sites.
[0030] Example 1 Under normal conditions, the splicing of two adjacent fire protection devices is usually done by direct welding or on-site drilling and bolting. However, when fire protection devices are in the working environment of a nuclear power plant, especially a nuclear power plant in operation, the sparks generated by direct welding or drilling can cause fires or even explosions. Therefore, an adjustable fixing structure is needed to splice adjacent fire protection devices to ensure the safe and stable operation of the nuclear power plant.
[0031] Reference Figure 1 An adjustable fixed structure for avoiding hot work sites includes a connector 1 and a connecting plate 11. Specifically, the connector 1 is a reinforced concrete column, fixedly connected to one side of the connecting plate 11. The connector 1 connects the connecting plate 11 and fire-resistant material, specifically a reinforced concrete column, with the reinforced concrete column located within the column. The connector 1 and the connecting plate 11 cooperate to form a connecting assembly. Two connecting assemblies are arranged sequentially, with the connecting plates 11 of the two assemblies facing each other. A telescopic member 2 is provided between the two connecting plates 11 to adjust the distance between them.
[0032] Reference Figure 1 The telescopic component 2 includes a telescopic block 21 and a telescopic cylinder 22. One end of the telescopic block 21 is inserted into one end of the telescopic cylinder 22, and the other end of the telescopic block 21 is fixedly connected to one of the connecting plates 11 on the side away from the connecting component 1. The other end of the telescopic cylinder 22 is fixedly connected to another connecting plate 11 on the side away from the connecting component 1. The telescopic block 21 slides within the telescopic cylinder 22 along the length of the telescopic cylinder 22, and the telescopic block 21 and the telescopic cylinder 22 are slidably connected. The cross-sectional shape of both the telescopic cylinder 22 and the telescopic block 21 is polygonal, such as a triangle, rectangle, or pentagon. The accompanying drawings of this application only show the case where the cross-sectional shape is rectangular. The telescopic block 21 and the telescopic cylinder 22 adopt a polygonal structure. During the telescopic process, the telescopic cylinder 22 limits the telescopic block 21, which is beneficial to improving the convenience of the adjusting component 3 in positioning the telescopic block 21 and the telescopic cylinder 22.
[0033] Reference Figure 1 The telescopic block 21 and the telescopic cylinder 22 are both fixedly connected to one end of the connecting plate 11 along the length direction. The telescopic block 21 and the telescopic cylinder 22 are located below the connecting plate 11, which can provide greater support force during the force process and improve the connection stability of the telescopic block 21 and the telescopic cylinder 22.
[0034] Reference Figure 1An adjusting member 3 is provided between the two connecting plates 11. The adjusting member 3 is used to adjust the overall length of the telescopic member 2, so that the telescopic block 21 can slide inside the telescopic cylinder 22. The adjusting member 3 includes a first positioning plate 31, a second positioning plate 32, a threaded rod 33, and multiple nuts 34. The first positioning plate 31 and the second positioning plate 32 are directly opposite each other. The threaded rod 33 passes through the first positioning plate 31 and the second positioning plate 32. The first positioning plate 31 and the second positioning plate 32 can slide along the length direction of the threaded rod 33. The multiple nuts 34 are threaded to the outside of the threaded rod 33 and are respectively located on both sides of the first positioning plate 31 and the second positioning plate 32 along the thickness direction. The multiple nuts 34 cooperate to position the first positioning plate 31 and the second positioning plate 32. The first positioning plate 31 is fixedly connected to the outside of the telescopic block 21, and the second positioning plate 32 is fixedly connected to the outside of the telescopic cylinder 22. The first positioning plate 31 moves closer to or further away from the second positioning plate 32, thereby realizing the sliding of the telescopic block 21 inside the telescopic cylinder 22, which improves the convenience of adjusting the distance between the two connecting plates 11.
[0035] Reference Figure 1 The number of adjusting components 3 is multiple sets, which are arranged around the circumference of the telescopic cylinder 22. The multiple sets of adjusting components 3 together position the telescopic block 21 and the telescopic cylinder 22. The telescopic cylinder 22 has multiple through holes 23 along its length. The fixing bolts pass through the through holes 23 and fit against the telescopic block 21 to fix the telescopic block 21, thereby improving the connection stability between the telescopic block 21 and the telescopic cylinder 22.
[0036] The implementation principle of Embodiment 1 of this application is as follows: The telescopic cylinder 22 and the telescopic block 21 adopt a polygonal structure. The telescopic cylinder 22 limits the telescopic block 21. The telescopic block 21 moves inside the telescopic cylinder 22 to adjust the distance between the two connecting plates 11. Multiple nuts 34 position the first positioning plate 31 and the second positioning plate 32, thereby positioning the telescopic cylinder 22 and the telescopic block 21. The telescopic block 21 and the telescopic cylinder 22 are located below the connecting plate 11, which can provide greater support force during the force process and improve the stability of the fire protection device connection.
[0037] Example 2 Reference Figure 2 The difference between this embodiment and embodiment 1 is that the first positioning plate 31 and the second positioning plate 32 are both fixedly connected to one side of the connecting plate 11 along the length direction. The first positioning plate 31 and the second positioning plate 32 directly drive the two connecting plates 11 to move closer or further away from each other, which further improves the convenience of adjusting the distance between the two connecting plates 11.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
