[0035] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0036] The core of the present utility model is to provide a console for earthquake - resistant large - screen multi - screen installation, which can be carried in the narrow transportation environment of the nuclear power plant main control room.

[0037] In order to enable those skilled in the art to better understand the technical solutions provided by the present utility model, the present utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0038] Specifically, please refer to Figures 1 - 10 , a console for earthquake - resistant large - screen multi - screen installation provided by the present utility model is applied in the nuclear power plant main control room and specifically includes: a console main frame 100 and a screen assembly 200.

[0039] The console main frame 100 includes a plurality of frame bases and a plurality of frame tops. The plurality of frame bases are arranged side by side, and the sides of adjacent frame bases are in contact and detachably connected. One frame top is detachably disposed on the top of one frame base, and the sides of adjacent frame tops are in contact and detachably connected. The thickness of the lower end of the frame base is greater than that of its upper end, so as to form a tabletop between the upper end and the lower end of the frame base, and the tabletop is used to support the bottom of the screen assembly 200 to improve the connection stability of the screen assembly 200.

[0040] The screen assembly 200 includes multiple spliced screen units, and the screen assembly 200 is detachably connected to the front of the top of the frame and the front of the upper end of the frame base.

[0041] The console for earthquake-resistant large-screen multi-screen installation provided by this solution includes a console main frame 100 and a screen assembly 200, which adopts a split design. The console main frame 100 is set to be composed of multiple frame bases and multiple frame tops that are detachably connected. At the same time, the screen assembly 200 is composed of multiple spliced screen units. During the process of transporting to the main control room of the nuclear power plant outdoors, independent components such as the frame base, the frame top, and the screen unit can be separately transported into the main control room through the transportation channels and elevators of the nuclear power plant, and then the independent components are assembled together and tightly connected by fasteners. With such a setting, it is possible to move the console for earthquake-resistant large-screen multi-screen installation in the narrow transportation environment of the main control room of the nuclear power plant.

[0042] In a specific embodiment, the frame bases and the frame tops correspond one by one. The number of multiple frame bases is two, specifically including a first frame base 110 and a second frame base 120. The number of multiple frame tops is two, specifically including a first frame top 130 and a second frame top 140. The sides of the first frame base 110 and the second frame base 120 are attached and detachably connected. The first frame top 130 is detachably arranged on the top of the first frame base 110, and the second frame top 140 is detachably arranged on the top of the second frame base 120. The sides of the first frame top 130 and the second frame top 140 are attached and detachably connected. The thickness of the lower ends of the first frame base 110 and the second frame base 120 is greater than that of the upper ends, so as to form a tabletop between the upper and lower ends of the first frame base 110 and the second frame base 120, and the tabletop is used to support the bottom of the screen assembly 200.

[0043] The screen assembly 200 includes multiple spliced screen units, and the screen assembly 200 is detachably connected to the front of the upper ends of the first frame top 130, the second frame, the first frame base 110, and the second frame base 120.

[0044] Of course, the number of the frame base, the frame top, and the screen unit can be one, two, or more than three, and can be adaptively selected according to actual needs, and will not be further limited here.

[0045] For a better storage device, a drawer 150 and / or a front door 160 are provided at the lower end of the frame base. The drawer 150 is arranged at the lower end of the frame base in a pull-out manner, such as for placing a keyboard and a mouse. One side of the front door 160 is hinged to the frame base, and larger items such as a printer, a switch, a computer mainframe, a 24V power supply, and a screen switch matrix can be placed. Of course, the drawer 150 and the front door 160 can also be installed simultaneously. For example, the drawer 150 is arranged near the tabletop at the lower end of the frame base, and the front door 160 is arranged in the remaining space at the lower end of the frame base. The interior of the front door 160 has a storage space.

[0046] The front door 160 is a detachable built-in door with ventilation holes on it. Dust-proof filter cotton is installed on the ventilation holes, which can both ventilate and prevent dust. A door pin is provided at the lower part of the front door 160, which can be inserted into the main frame 100 of the console. Quick-opening push locks are provided on the upper left and right sides, which is convenient for disassembly.

[0047] For example, below the screen assembly 200, a push-pull hidden drawer is designed, in which a mouse and a keyboard are arranged, and functions such as monitoring, analysis, and warning can be operated on the large screen. The front door 160 is set in an embedded manner, and devices such as a power supply, a switch, a computer mainframe, a fax machine, and a printer are arranged inside the storage space. Since the back of the main frame 100 of the console is against the wall, all maintenance and installation are designed as front maintenance. The large screen is installed with an adjustable bracket design, which can freely adjust the position and angle, facilitating the operator to obtain the best working perspective and operation convenience. It can make up for the requirement that the existing console structure cannot meet the layout of devices such as a mouse, a keyboard, a printer, and a fax machine.

[0048] When the wall of the main control room is at a corner position, in order to make full use of the space at the corner, the thicknesses of multiple frame bases can be designed to be different, and the thickness of the top of the interconnected frames is the same as that of the frame base. The back of the main frame 100 of the console is against the wall, showing a special-shaped "L" layout. It effectively solves the problems of the special-shaped wall of the main control room, which can only be maintained and installed from the front, and is not easy to install due to its high height.

[0049] One of the frame tops with a smaller thickness among multiple frame tops includes two columns, a front panel, a back panel, and a top cover. The two columns are respectively located on both sides. The front panel is arranged on the front side of the two columns, the back panel is arranged on the back side of the two columns, and the top cover is arranged on the top of the two columns. The front panel, the back panel, and the top cover form a rectangular frame on the two columns.

[0050] Among the tops of multiple frameworks, the one with a greater thickness includes four columns, two side plates, a front panel, a back panel, and a top cover. The four columns are respectively located at the four inflection points of a rectangle. The two side plates are respectively located on the two columns on both sides. The front panel is arranged on the two columns on the front side. The back panel is arranged on the two columns on the back side. The top cover is arranged on the tops of the four columns. In this way, the two side plates, the front panel, the back panel, and the top cover enclose the four columns to form a rectangular framework. Since the top of this framework has a greater thickness, columns need to be added to improve the overall structural strength.

[0051] The top of the framework is assembled in a way of loose parts. The top of the framework with a smaller thickness (such as Figure 5 the first framework top 130 shown) can be disassembled into 5 structural parts. The top of the framework with a greater thickness (such as Figure 5 the second framework top 140 shown) can be disassembled into 9 structural parts, and the weight of each structural part does not exceed 10 kilograms. One or two people can manually carry a single structure to the main control room for installation. All tops of the frameworks are connected by bolts, and multiple bends and stiffeners are adopted to ensure the seismic performance above the console. The top of the framework is installed at the top. It is necessary to control the weight of a single piece and meet the seismic requirements. It should be convenient for installation and maintenance, and the joint gap of each piece should be ensured, which is beautiful and practical.

[0052] A rear door 170 is also provided at the rear of the lower end of the framework base. A side door is also provided at the side of the lower end of the framework base. Both the rear door 170 and the side door are detachable door panels.

[0053] In the actual installation process, first, install the rear door 170, and move the framework base to the position against the wall. Arrange multiple framework bases side by side, and then connect them by bolts. Secondly, install the tops of the frameworks on the framework base in sequence and tighten them with bolts. Then, install the pull-out drawers. The four drawers 150 are installed in a way of four groups of silent sliding rails. The drawers 150 and the framework base are slidably connected through the silent sliding rails. Install a micro-lock on the drawers 150 to facilitate locking and unlocking and meet the seismic requirements. Finally, install the front door 160. An embedded door body is adopted. Two bolts are provided at the lower part of the front door 160, which can be inserted into the framework base. Door locks are provided at the upper parts on both sides of the front door 160. Rotating 90° can lock the front door 160 conveniently and quickly and meet the seismic requirements.

[0054] Since the screen in the prior art is a whole and does not need to be adjusted in position, while in this application, a large screen is formed by splicing multiple screen units, and the installation positions of the screen units need to be adjusted. Therefore, a number of installation holes are provided on the front sides of the framework base and the framework top. By adjusting the positions of the screen units, the installation positions on the screen units are aligned with the corresponding installation holes of the console main framework 100, so as to realize the connection between the installation holes and the screen assembly 200 by bolts.

[0055] In the existing main control room of nuclear power plants, there is no console like the one in this case. In this case, a new design of a large-screen and multi-screen console with earthquake resistance function is added. In a specific embodiment, the console with earthquake-resistant large-screen multi-screen installation adopts a split design, which specifically includes a main console frame 100 and a screen assembly 200 arranged on the front of the main console frame 100.

[0056] The screen assembly 200 is composed of 4 65-inch screen units spliced together to form a large screen, ensuring no gap in the middle of the large screen. The upper and lower two screen units on the left and the upper and lower two screen units on the right form a "field" shape. The width of each screen unit is about 1450 mm, the height is about 850 mm, and the thickness is about 80 mm.

[0057] The main console frame 100 includes an upper end and a lower end. The upper end is used to support the screen assembly 200, and the lower end serves as a base and can also be used for storing items. A height of 900 mm needs to be left at the lower end of the main console frame 100 to arrange a push-pull drawer 150 for placing the keyboard and mouse. The remaining space is designed with a detachable front door 160, and equipment such as printers, switches, computer hosts, 24V power supplies, and screen switch matrices are placed inside. The keyboard and mouse are designed in the pull-out drawer 150 below the screen, which is convenient for operating the large screen for monitoring, early warning, analysis, etc. At the same time, the printer and fax machine are fixed therein, which not only meets the earthquake resistance requirements but also facilitates operations such as paper feeding and paper changing. Therefore, the maximum size of the main console frame 100 is width 3000 mm * height 2600 mm * thickness 1010 mm. Specifically, the main console frame 100 is divided into 4 parts: the top of the first frame 130 (i.e., the upper left part) (width 1500 mm * height 600 mm * thickness 400 mm), the base of the first frame 110 (i.e., the lower left part) (width 1500 mm * height 2000 mm * thickness 400 mm), the top of the second frame 140 (i.e., the upper right part) (width 1500 mm * height 600 mm * thickness 1010 mm), and the base of the second frame 120 (i.e., the lower right part) (width 1500 mm * height 2000 mm * thickness 1010 mm).

[0058] The base of the first frame 110 and the base of the second frame 120 are respectively welded by steel plates. Before assembly, the four parts of the main console frame 100 are respectively transported into the main control room by elevator. After being transported in place, the base of the first frame 110 and the base of the second frame 120 are bolted together to form an integral console base, ensuring that the parallel cabinet gap in the middle is less than 0.5 mm. On this basis, the top of the first frame 130 (600 mm high) and the top of the second frame 140 (600 mm high) are installed.

[0059] The top of the first frame 130 is an assembled structure composed of five structural members: the left vertical column 131, the right vertical column 132, the first back panel 134, the first top cover 135, and the first front panel 133. The top of the second frame 140 is an assembled structure composed of nine structural members: the left front vertical column 141, the left rear vertical column 144, the right front vertical column 142, the right rear vertical column 143, the left side panel 149, the right side panel 148, the second back panel 146, the second top cover 147, and the second front panel 145.

[0060] When the wall of the main control room is at a corner position, the wall of the main control room is an irregular wall. It is necessary to place the main frame 100 of the console close to the wall and ensure that the four screen units of the screen assembly 200 are flush. Therefore, the thickness of the top 130 of the first frame and the base 110 of the first frame is designed to be 400 mm, and the thickness of the top 140 of the second frame and the base 120 of the second frame is designed to be 1010 mm. The main frame 100 of the console forms an L-shaped irregular console, which can not only meet the transportation of narrow elevators, but also ensure that the operation table meets the seismic requirements, and also takes into account reasonable layout, beauty and practicality.

[0061] Compared with the prior art, from the perspective of project implementation, the utility model is more suitable for renovation projects, such as nuclear power plants transported by elevators and narrow channels. It has the advantages of miniaturization, light weight, high safety performance, convenient installation, and the lowest cost.
