Description

Technical Field

[0001] The invention relates to the field of spray devices, and in particular to an emergency spray water circulation device for building construction and a use method thereof. Background Art

[0002] Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the sprinkler head splash plate to extinguish the fire. There are pendent sprinkler heads, upright sprinkler heads, ordinary sprinkler heads, sidewall sprinkler heads, etc. The principle of the sprinkler head is that it is a water spraying device that automatically starts sprinkling water within a predetermined temperature range under the action of heat.

[0003] For example, the patent with application number 202122560265.5 discloses a new type of fire sprinkler head, which relates to the field of fire protection engineering and aims to solve the problem of water resources being wasted when a fire sprinkler head is accidentally triggered to spray water. The key points of its technical solution are: a new type of fire sprinkler head, including a pipe joint, a copper block detachably connected to the pipe joint, a yoke arm fixedly connected to the bottom of the pipe joint, and a glass tube detachably connected to the yoke arm to support the copper block, wherein the pipe joint is provided with a groove coaxially arranged with the pipe joint at one end of the thread, and a closing component for controlling the opening and closing of the pipeline is provided at the bottom of the groove. A new type of fire sprinkler head of the utility model can temporarily stop the water flow in the pipe joint when the fire sprinkler head is working in non-fire accident situations, giving people sufficient time to close the water valve.

[0004] The patent with application number 202321817406.X discloses a stable fire sprinkler head, which relates to the technical field of fire fighting equipment and aims to solve the problem of insect corpses or accumulated impurities adhering to the surface of the splash plate. When the sprinkler head sprays water, the water flow impacting the insect corpses or impurities on the splash plate will cause the water flow to be diverted, resulting in a spraying blind area, affecting the fire extinguishing effect. The key points of its technical solution are: it includes a column head and a yoke arm fixedly connected to the bottom of the column head, a limit block fixedly connected to the yoke arm, a bearing member detachably connected to the limit block, the inner ring height of the bearing member is greater than the outer ring height, and the inner ring of the bearing member is higher than the outer ring. The part of the fan blade group is fixedly connected. The stable fire sprinkler head of the utility model uses a bearing member detachably connected to the limit block and a fan blade group fixedly connected to the inner ring of the bearing member. When the fire sprinkler head sprays water, the rotating water splashing method reduces the occurrence of the splashing blind area, reduces the influence of insect corpses on splashing water extinguishing, and improves the stability of the sprinkler head.

[0005] However, the above-mentioned fire sprinkler heads and similar fire sprinkler heads are usually installed on the top of the house when in use. When the fire is located at the bottom of the room, the fire is often large before the fire sprinkler heads can reach the activation temperature to spray water.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Example 1

[0030] like Figure 1-6 As shown, an emergency sprinkler water circulation device for building construction includes a fire water tank 1, the top of the fire water tank 1 is fixedly connected to the right end of the upper sprinkler pipe 3, the fire water tank 1 is communicated with the upper sprinkler pipe 3, a plurality of fire sprinkler heads 4 are installed on the upper sprinkler pipe 3, a plurality of lower sprinkler pipes 7 are arranged at the bottom of the fire water tank 1, adjacent lower sprinkler pipes 7 are connected by a sprinkler mechanism 6, the right end of the rightmost lower sprinkler pipe 7 is connected to the water pump 2, the water pump 2 is installed at the bottom of the fire water tank 1, the left end of the upper sprinkler pipe 3 is fixedly connected and communicated with the top end of the connecting pipe 5, and the left end of the leftmost lower sprinkler pipe 7 is fixedly connected and communicated with the bottom end of the connecting pipe 5.

[0031] When in use, the upper sprinkler pipe 3 is installed on the roof, the lower sprinkler pipe 7 and the sprinkler mechanism 6 are installed underground, the connecting pipe 5 is buried in the wall, and the water pump 2 pumps the water in the fire water tank 1, and then returns the water to the fire water tank 1 through the lower sprinkler pipe 7, the connecting pipe 5, and the upper sprinkler pipe 3 to form a cycle. When a fire occurs on the ground, the sprinkler mechanism 6 at the bottom will first spray water to extinguish the fire. If the fire continues and the temperature continues to rise, the fire sprinkler head 4 will start spraying water under the action of high temperature to assist in extinguishing the fire.

[0032] Example 2

[0033] like Figure 1-6 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: the spray mechanism 6 includes a spray pipe 19, and openings 24 are opened on both sides of the spray pipe 19, the openings 24 on the left and right sides of the spray pipe 19 are respectively fixedly connected to and communicated with the lower spray pipes 7 on the left and right sides thereof, the top edge of the spray pipe 19 is fixedly connected to the bottom of the silicone sealing ring 20, a top cover 8 is arranged above the silicone sealing ring 20, and the top of the silicone sealing ring 20 is fixedly connected to the top cover 8, a bottom cover 23 is arranged below the spray pipe 19, and the bottom of the spray pipe 19 is fixedly connected to the bottom cover 23.

[0034] The spray mechanism 6 also includes a fixed column 17, which is located in the spray pipe 19, and the fixed column 17 is located below the opening 24. The edge of the fixed column 17 is fixedly connected to the inner wall of the spray pipe 19, and a guide hole 16 is opened in the upper center of the fixed column 17, and a threaded hole 25 is opened in the lower center of the fixed column 17. The guide hole 16 is connected to the threaded hole 25, and the diameter of the guide hole 16 is smaller than the diameter of the threaded hole 25. A first guide rod 9 is arranged in the guide hole 16, and the first guide rod 9 is slidably connected to the guide hole 16. The upper end of the first guide rod 9 is rotatably connected to the bottom of the top cover 8, and a threaded rod 18 is arranged below the first guide rod 9, and the top of the threaded rod 18 is fixedly connected to the bottom of the first guide rod 9. The spray mechanism 6 also includes a plurality of second guide rods 22, which are located at the top edge of the spray pipe 19, penetrate the top of the spray pipe 19, and are fixedly connected to the bottom of the top cover 8 at the top of the second guide rod 22. A buffer spring 21 is sleeved on the second guide rod 22, and the lower end of the buffer spring 21 is fixedly connected to the spray pipe 19, and the upper end of the buffer spring 21 is fixedly connected to the top cover 8. The spray mechanism 6 also includes a transverse insertion rod 13, which is located above the fixed column 17, penetrates the first guide rod 9, and is slidably connected to the first guide rod 9. A limit plate 14 is fixedly connected to the right end of the insertion rod 13, and the transverse insertion rod 13 is fixedly connected to one end of the elastic rope 12, which is wound on the first guide rod 9, and the other end of the elastic rope 12 is fixedly connected to the first guide rod 9. A limit plate slot 15 is provided on the top of the fixed column 17, and the limit plate 14 is plugged into and matched with the limit plate slot 15.

[0035] The top cover 8 is exposed on the ground. When a fire occurs on the ground, the high temperature causes the temperature of the top cover 8 to rise rapidly, causing the top cover 8 to melt the silicone sealing ring 20 in contact with it, so that the top cover 8 and the spray pipe 19 are no longer connected together. Under the elastic force of the buffer spring 21, the top cover 8 is driven to move upward. At this time, the water flowing through the lower spray pipe 7 is sprayed out through the top of the spray pipe 19 to hit the top cover 8, and then splashes everywhere to extinguish the fire.

[0036] When the top cover 8 moves upward, the first guide rod 9 and the threaded rod 18 are driven to move upward synchronously. When the threaded rod 18 contacts the fixing column 17, the top cover 8, the first guide rod 9 and the threaded rod 18 stop moving upward.

[0037] During the upward movement of the first guide rod 9, the limit plate 14 is driven to move upward synchronously, so that the limit plate 14 is disengaged from the limit plate slot 15. At this time, the water flow impacts the limit plate 14 (the position of the limit plate 14 is set at an angle, so that the limit plate 14 is fixed to rotate in one direction when impacted by the water flow), so that the limit plate 14 drives the first guide rod 9 to rotate through the transverse insertion rod 13, so that the first guide rod 9 drives the threaded rod 18 to rotate, so that the threaded rod 18 is threadedly connected with the threaded hole 25, thereby fixing the threaded rod 18 on the fixed column 17, and then fixing the position of the top cover 8 to prevent debris from falling and pressing down on the top cover 8 during a fire, causing the top cover 8 to block the sprinkler pipe 19. When the limit plate 14 is impacted by the water flow, it drives the transverse insertion rod 13 to be inserted into the first guide rod 9, so that the first guide rod 9 pulls the elastic rope for buffering, preventing the transverse insertion rod 13 from breaking due to the impact.

[0038] Example 3

[0039] like Figure 1-6 As shown, when other parts are the same as those in Example 2, the difference between this embodiment and Example 2 is that: the spray mechanism 6 also includes a silicone sheet 11, which is sleeved on the top of the first guide rod 9, the silicone sheet 11 is fixedly connected to the first guide rod 9, and the edge of the silicone sheet 11 is fixedly connected to the inner wall of the spray pipe 19. A plurality of spikes 10 are arranged below the silicone sheet 11, and the plurality of spikes 10 are arranged around the first guide rod 9, and the lower ends of the spikes 10 are fixedly connected to the surface of the first guide rod 9. By providing the silicone sheet 11, the water in the spray pipe 19 can be separated from the top cover 8 to prevent the water from cooling the top cover 8 in case of fire, so that the top cover 8 cannot melt the silicone sealing ring 20. And when the silicone sealing ring 20 is melted and the first guide rod 9 moves up, the first guide rod 9 will pull the silicone sheet 11, so that the spikes 10 pierce the silicone sheet 11, so that the water flow can be smoothly sprayed out from the top of the spray pipe 19.
