[0002] In a passive nuclear power plant, the containment cooling system of the passive nuclear power plant completely relies on passive natural forces to complete the heat transfer process after the accident. Among them, the containment cooling auxiliary water tank is arranged in the plant area. When the cooling water in the water tank is needed, a recirculation pump is needed to transport the cooling water to the containment cooling water tank or directly to the surface of the containment. In order to ensure the performance of the recirculation pump and reduce the resistance along the pipeline from the passive containment cooling auxiliary water tank to the recirculation pump, it is required that the pump inlet pipeline should not exceed 1 90° elbow when arranged, so this section of the pipeline is arranged above the ground, about 1 meter from the ground.

[0031] As Figures 1 to 4 shown, this embodiment provides a pipeline protection device, which includes a semi-circular protection member 3, at least two support assemblies 1 and at least two fixing assemblies 2. Since the pipeline 4 is arranged above the ground and is about 1 meter away from the ground, the support assembly 1 is provided to increase the height of the fixing assembly 2, so as to facilitate fixing the pipeline 4 through the fixing member 21 and ensure that the pipeline 4 does not shake during operation; since the items carried by the typhoon can hit the pipeline 4 from above or on both sides of the pipeline 4, a protection member 3 is provided on the support assembly 1 and the protection member 3 is covered above the pipeline 4. In this way, the protection member 3 can provide protection for the upper part or both sides of the pipeline 4, ensuring the safety and stability of the pipeline 4 during operation. At the same time, the shape of the protection member 3 is set as semi-circular, so that there is a large gap between the protection member 3 and the pipeline 4, which is convenient for the staff to enter from the opening of the protection member 3 to perform operations such as inspection and repair of the pipeline 4. Among them, both the support assembly 1 and the fixing assembly 2 are set to at least two, which can enhance the structural strength of the pipeline protection device, and thus improve the stability and safety of the pipeline protection device. Using the pipeline protection device of the present utility model, compared with the method of building a factory building to protect the pipeline in the prior art, it has a small floor area and low cost, effectively solving the problems of large floor area and inconvenient inspection and maintenance of the pipeline protection device in the prior art.

[0032] Specifically, the protection member 3 includes a protective cover 31 and a plurality of reinforcing rib plates 32. The plurality of reinforcing rib plates 32 are arranged at intervals on the side of the protective cover 31 facing the pipeline 4, which can strengthen the structural strength of the protective cover 31, and thus improve the stability and safety of the pipeline protection device. Among them, the shape of the protective cover 31 is semi-circular, and the opening of the protective cover 31 faces the ground, which is convenient for the staff to enter from the opening of the protective cover 31, so as to facilitate operations such as inspection and maintenance of the pipeline 4.

[0033] Preferably, the protective cover 31 is made of reinforced concrete. Among them, the reinforced concrete material has the advantages of good durability and high compressive strength. Reinforced concrete is mainly composed of sand, stone, cement and steel bars.

[0034] Optionally, the support assembly is made of reinforced concrete, which has the advantages of high compressive strength and good durability.

[0035] In this embodiment, the protective member 3 further includes a lifting lug 33. The lifting lug 33 can be disposed on the side of the protective cover 31 facing away from the pipeline 4.

One end of the fixing frame 22 is connected to the support assembly 1, and the fixing member 21 is connected to the other end of the fixing frame 22. Such an arrangement facilitates the connection between the fixing member 21 and the support assembly 1, and also ensures the connection strength of the fixing member 21.

[0038] Among them, the fixing member 21 includes a connecting plate 211 and a U-shaped pipe clamp 212 which are connected to each other. The connecting plate 211 is used to connect to the other end of the fixing frame 22, and the concave surface of the U-shaped pipe clamp 212 and the connecting plate 211 are both in contact with the pipeline 4, so as to achieve the purpose of fixing the pipeline 4.

[0039] Or, as Figure 5 shown, the fixing member 21 includes a connecting frame 213, a first jacket 214 and a second jacket 215.

[0040] Or, as Figure 6 shown, the fixing member 21 includes a first fixing plate 216, a second fixing plate 217, a third fixing plate 218 and a fourth fixing plate 219. In this embodiment, the first fixing plate 216 and the second fixing plate 217 are spaced apart on the fixing frame 22 and are both in contact with two opposite side walls of the pipeline 4. The two ends of the third fixing plate 218 and the two ends of the fourth fixing plate 219 are respectively connected to the first fixing plate 216 and the second fixing plate 217, and the third fixing plate 218 and the fourth fixing plate 219 are both in contact with two opposite side walls of the pipeline 4. In this way, the four side walls of the pipeline 4 can be contacted, so as to achieve the purpose of fixing the pipeline 4.

[0041] Specifically, the support component 1 includes a support column 11, a support platform 12, and an embedded plate 13. One end of the support column 11 can be set on the ground, and one end of the support platform 12 is connected to the other end of the support column 11, which can increase the height of the support platform 12. At the same time, the embedded plate 13 is set at the other end of the support platform 12. Among them, the materials of the embedded plate 13 and the fixing component 2 are both metal, so that the embedded plate 13 can be connected to the steel bars inside the support platform 12, and the fixing component 2 is connected to the embedded plate 13, so that the fixing component 2 and the support platform 12 can be connected. Among them, the protective part 3 can be set on the support platform 12, and the support platform 12 plays a supporting role.

[0042] Furthermore, both sides of the support platform 12 have limit protrusions 121. The setting of the limit protrusions 121 can limit the protective part 3 to prevent the protective part 3 from falling off, and can also play a guiding role during installation.
