Description

Technical Field

[0001] This utility model relates to the field of nuclear power engineering measurement technology, specifically to a measurement control point protection box device for nuclear power engineering. Background Technology

[0002] In the construction, operation, and maintenance of nuclear power plants, precise measurement control points are fundamental to ensuring the accurate spatial location and elevation of structures, achieving design objectives, and guaranteeing the safe and stable operation of the reactor. These control points are typically embedded inside or near critical structures, and their precise coordinates and elevation data directly affect the accuracy of various aspects, including civil engineering, equipment installation, and pipeline connections.

[0003] A protective device is usually installed on the outside of the control point to prevent the control point from being damaged or displaced. Traditional measurement control point protection boxes are usually fixedly connected to the tripod. The protection box is not easy to disassemble after construction is completed. Moreover, the protection box is fixed to the mounting surface with bolts. The single fixing method is prone to loosening or failure. The connection is not reliable and its protective performance is poor when in use. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0028] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] Combined with appendix Figure 1 As shown, a measurement control point protection box device for nuclear power engineering includes a box body 1, which is an equilateral triangular structure. The bottom surface of the box body 1 is provided with a mounting plate 2, and the mounting plate 2 is provided with mounting holes 3.

[0030] The equilateral triangle structure of the box 1 provides a stable triangular support frame, enhances the rigidity of the overall structure, prevents the box 1 from deforming or tilting due to external forces, and improves the protective force of the box 1. The mounting holes 3, together with bolts or expansion screws, enable reliable fixing of the box 1.

[0031] After construction is completed, it is generally necessary to dismantle box 1 to reduce its footprint. Therefore, in conjunction with the attached... Figure 2 As shown, there are multiple connecting blocks 4 arranged in a circular array on the inner wall of the box 1. The connecting blocks 4 are connected to the legs by connecting components. There are three connecting blocks 4, which are respectively located on the inner wall of each side of the box 1. The number of connecting components is the same as the number of connecting blocks 4.

[0032] Combined with appendix Figure 2 and Figure 3 As shown, the tripod includes legs, and a fixing member 5 is connected to the top of the legs. The fixing member 5 is provided with a plug 6, and the plug 6 is provided with a locking hole 7.

[0033] Combined with appendix Figure 3 , Figure 6 and Figure 7As shown, the connecting block 4 is provided with a slot 8 that is adapted to the insert block 6. The connecting component includes a locking block 9. The outer wall of the box body 1 is provided with a through hole that communicates with the slot 8. The locking block 9 is inserted into the through hole. Sliding grooves 10 are provided on both sides of the through hole. A sliding plate 11 that slides in the sliding groove 10 is connected to the locking block 9. A spring 12 is connected to the sliding plate 11. One end of the spring 12 is connected to the sliding groove 10.

[0034] Among them, the combination of appendix Figure 3 and Figure 5 As shown, the insert 6 has a triangular structure, the protruding end of the latch 9 and the contact surface with the insert 6 are inclined, and the other end of the latch 9 extends to the outside of the box 1 and is provided with a pull hole;

[0035] With the above structure, when using the box 1 to protect the measurement control point, the box 1 is placed over the measurement control point, the tripod is poured with concrete, and after the concrete dries, the tripod is firmly fixed to the ground. Its triangular support structure has high stability. At the same time, the tripod and the box 1 are connected by a connecting component. The insert 6 is inserted into the slot 8. The triangular insert 6 cooperates with the locking block 9 with the inclined structure, making the locking block 9 easier to retract under force. When the insert 6 is inserted to the position where the locking hole 7 is aligned with the locking block 9, the locking block 9 pops out under the action of the spring 12 and inserts into the locking hole 7, forming a mechanical lock, keeping the connecting block 4 and the tripod locked, and resisting loosening caused by external force.

[0036] Once construction is complete, to remove the box 1, simply pull the locking block 9 outwards from the box 1, causing the locking block 9 to disengage from the locking hole 7, thus detaching the connecting block 4 from the leg.

[0037] Combined with appendix Figure 3 As shown, the fastener 5 has a T-shaped structure. A reinforcing rib 13 is provided on one side of the insert block 6. The reinforcing rib 13 is designed with a triangular cross-section structure and is integrally formed with the fastener 5. The reinforcing rib 13 can disperse local stress and avoid stress concentration, thereby significantly improving the bending and torsional resistance of the fastener 5.

[0038] Because a large number of measurement control points need to be set up on the construction site of nuclear power projects, and it is inconvenient to find these control points, therefore, based on the above, and in conjunction with the appendix... Figure 4 and Figure 5 As shown, the box 1 has a device cavity 14 inside, and a flashing light 15 is connected inside the device cavity 14. A storage battery 16 is located below the device cavity 14 inside the box 1. The flashing light 15 is electrically connected to the storage battery 16 through wires. Photovoltaic panels 17 are respectively provided on the outer surface of the box 1. The photovoltaic panels 17 are electrically connected to the storage battery 16 through a photovoltaic controller. The device cavity 14 is provided with a transparent glass window. The glass window protects the flashing light 15 from dust, moisture or physical damage, while ensuring that the light can be clearly transmitted to meet the warning requirements.

[0039] During the day, the photovoltaic panel 17 converts light energy into electrical energy through the photovoltaic controller and stores it in the battery 16, achieving energy self-sufficiency and reducing dependence on external power sources. The flashing light 15 is in standby mode. At night or in low light conditions, the flashing light 15 is activated and flashes, powered by the battery 16, emitting warning light through the glass window to remind personnel or equipment to pay attention to the location of the measurement control point, preventing misoperation or collision, thereby improving the protective performance of the housing 1.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
