Description

Technical Field

[0001] This utility model relates to the field of marine oil engineering technology, and in particular to a rain spray test protection device. Background Technology

[0002] Fire sprinkler systems are a type of fire protection facility widely used in the offshore petrochemical industry. Their function is to spray water mist onto the area around equipment and facilities in a timely manner when a fire occurs, cool and de-temperature the equipment in the relevant area, block the fire source, control the spread of the fire, and effectively protect the safety of personnel and equipment.

[0003] Dew sprinkler fire suppression systems require regular maintenance and reliability testing. During testing, seawater sprays onto the equipment and facilities in the protected area, causing corrosion and damage to electrical and instrumentation equipment, thus shortening the lifespan of these facilities and increasing maintenance costs. Furthermore, given the dense deployment and wide coverage of offshore production facilities, the testing process can result in extensive seawater spraying and coverage within the protected area, leading to severe water accumulation on skids and decks. This necessitates deck water cleanup, resulting in significant workload for on-site personnel. Utility Model Content

[0017] Figure 1 This is a schematic diagram of the structure of this utility model.

[0018] The components include: 1. Liquid collection tank; 2. U-shaped channel; 3. Connecting plate; 4. Bolt hole; 5. Fixing plate; 6. Short section; 7. Drain outlet; 8. Fire-fighting pipeline. Detailed Implementation

[0019] The present patent application will be further described below with reference to the embodiments.

[0020] like Figure 1 As shown, a rain spray test protection device includes a liquid collection tank 1, which is the main component of the protection device. The liquid collection tank 1 has a size of 400mm*400mm*400mm and is made of carbon steel plate with a thickness of 2mm by welding.

[0021] A U-shaped groove 2 is provided at the connection between the liquid collection tank 1 and the fire protection pipeline 8. Specifically, a U-shaped groove 2 is formed downward from the middle of the upper edge of the two opposite side walls of the liquid collection tank 1. The U-shaped groove 2 is used to place the fire protection pipeline 8. The U-shaped groove 2 can be prefabricated and adjusted according to the size requirements of the fire protection pipeline 8.

[0022] Connecting pieces 3 are attached to the upper edges of the side walls of the liquid collection tanks 1 on both sides of the U-shaped channel 2. The connecting pieces 3 are located outside the liquid collection tanks 1 and are horizontally arranged, with bolt holes 4 formed on them. The connecting pieces 3 on both sides of the U-shaped channel 2 are connected by a fixing plate 5, which also has bolt holes 4. Bolts pass through the bolt holes 4 of the connecting pieces 3 and the fixing plate 5, thereby connecting the two connecting pieces 3 located on the same side of the liquid collection tank 1. This application uses detachable bolts to connect the connecting pieces 3 and the fixing plate 5, which can confine the fire-fighting pipeline 8 placed in the U-shaped channel 2 within the U-shaped channel 2. At the same time, the fixing plate 5 provides a fixing force point, which can fix this utility model below the sprinkler head to be tested.

[0023] This application features a through-hole formed in the center of the bottom of the sump 1, with the through-hole welded to a short section 6. The lower end of the short section 6 forms a drain port 7. The short section 6 is designed as a quick-connect coupling, facilitating the timely connection of a hose to drain the accumulated seawater to the deck drain.

[0024] When a sprinkler head needs to be tested, place the fire pipeline 8 near the sprinkler head to be tested in the U-shaped groove 2, while ensuring that the sprinkler head to be tested is placed in the liquid collection tank 1. Then, connect the connecting piece 3 and the fixing plate 5 with bolts, and then conduct a rain spray test. When the liquid level in the liquid collection tank 1 is high, discharge the seawater through the drain outlet 7 at the bottom of the liquid collection tank 1 to the floor drain.

[0025] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
