Description

Technical Field

[0001] This utility model belongs to the field of fence technology, and in particular relates to an assembled fence. Background Technology

[0002] In a nuclear power unit, the refueling pool and pressure vessel are closely connected. Foreign objects falling from the refueling pool can be introduced into the pressure vessel during the filling and draining of water. The pressure vessel is the main site for nuclear reactions in the reactor. Once a foreign object intrusion occurs, it is very likely to cause damage to equipment and fuel assemblies, thereby affecting the safe operation of the unit.

[0003] To prevent other foreign objects from entering, it is usually necessary to keep the foreign object control zone inside the fence closed. The existing fence has large gaps, so it is necessary to wrap the original fence with plastic sheeting, which increases the workload of setting up the foreign object control zone. In addition, the introduction of a large number of consumables such as plastic sheeting not only increases the risk of foreign objects but also increases the amount of radioactive waste to be disposed of. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] A typical embodiment of this utility model is as follows: Figure 1 As shown, an assembled fence includes posts 1, crossbars 2, and protective panels 3. Multiple posts 1 are provided and fixed side by side on the periphery of the foreign object prevention control area. The protective panels 3 are fixedly connected to the posts 1 through the crossbars 2.

[0024] like Figure 2As shown, the post 1 includes two parallel vertical plates 101 arranged symmetrically from left to right. Multiple connecting plates 102 are fixedly connected between the two vertical plates 101. The multiple connecting plates 102 are arranged side by side along the height direction of the post 1. The bottom ends of the two vertical plates 101 are connected by a base plate. A round tube 103 is fixedly connected to the lower surface of the base plate. The axis of the round tube 103 is perpendicular to the base plate. In use, the post 1 is fixed to the ground by inserting the round tube 103 into a pre-drilled hole in the ground. Ribs 104 are provided on the outer side of the bottom end of the two vertical plates 101. The ribs 104 are perpendicular to the vertical plates 101. By setting the ribs 104, the post 1 can be effectively prevented from shaking, thereby ensuring the stability of the fence.

[0025] like Figure 3 As shown, the vertical plate 101 has multiple mounting holes 105, which are arranged side by side along the length of the vertical plate 101. The mounting holes 105 on the two vertical plates 101 are arranged one-to-one. There are multiple horizontal bars 2, which are arranged corresponding to the mounting holes 105. The horizontal bars 2 are connected to the column 1 by passing through the two mounting holes 105 at the same height on the two vertical plates 101 in sequence.

[0026] In this embodiment, each vertical plate 101 is provided with two mounting holes 105, which are located at the upper part and the middle part of the vertical plate 101, respectively. There are two horizontal bars 2, which are respectively disposed in the two mounting holes 105 of the vertical plate 101.

[0027] The protective plate 3 is made of stainless steel. The perimeter edge of the protective plate 3 is folded inward. On the one hand, it can fit tightly with the adjacent protective plate 3, and on the other hand, it can fit tightly with the ground, avoiding gaps between adjacent protective plates 3 and between the protective plate 3 and the ground, thus playing a role in preventing foreign objects. On the other hand, it can prevent workers from being cut during installation and ensure the safety of fence construction.

[0028] Multiple sets of collars 301 are provided on the inner side of the protective plate 3. The multiple sets of collars 301 are respectively provided with multiple crossbars 2. Each set of collars 301 includes several collars 301 arranged side by side. The two ends of the crossbar 2 can be inserted into the corresponding collars 301, thereby realizing the connection between the crossbar 2 and the protective plate 3.

[0029] In this embodiment, four collars 301 are provided. The four collars 301 are fixed in pairs to the upper and middle parts of the inner side of the protective plate 3. The two collars 301 located on the upper part of the inner side of the protective plate 3 correspond to the horizontal bar 2 on the upper part of the column 1, and the two collars 301 located on the middle part of the inner side of the protective plate 3 correspond to the horizontal bar 2 in the middle part of the column 1. The two ends of the horizontal bar 2 can be inserted into the two collars 301 that are opposite to it, so that the protective plate 3 and the column 1 are fixedly connected.

[0030] By setting up protective panels 3, large gaps in the fence are avoided, the spacing is used to prevent foreign objects from entering, and the workload of setting up the foreign object control area is reduced, thus reducing the generation and disposal of radioactive waste.

[0031] A lifeline hole 106 is provided in the middle of the vertical plate 101. The lifeline holes 106 on the two vertical plates 101 are set accordingly. A lifeline 4 is passed through the lifeline hole 106, so that multiple columns 1 can be connected by the lifeline 4, which serves to fix the columns 1. At the same time, it can also provide an effective safety belt attachment point for workers to work near the edge of the pool, ensuring the safety of the workers.

[0032] In use, first insert the upright cylindrical tube downwards into the hole in the ground. The horizontal plate at the bottom acts as a good limiter, effectively ensuring the uniform height of the upright assembly, while the stiffening plates on both sides effectively prevent the upright assembly from wobbling on the ground. Then, pass the horizontal bar through the two mounting holes on the upright to fix the upright assembly. At the same time, the horizontal bar passes through the collar on the protective plate during its passage through the upright, providing support for the protective plate and fixing it to the upright. Finally, pass the lifeline through the lifeline hole on the upright, which not only further secures all the uprights but also provides an effective safety belt attachment point for personnel working near the edge of the pool.

[0033] This utility model achieves the enclosure of the foreign object control zone by setting up protective plates and fixing them to the columns set around the perimeter of the foreign object control zone with crossbars, so that there are no gaps between adjacent protective plates and between the protective plates and the ground. This prevents large gaps in the guardrail, reduces the workload of setting up the foreign object control zone, and reduces the generation and disposal of radioactive waste.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
