This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.

[0019] See also Figures 1 to 4 The present embodiment discloses a building fire extinguishing device, comprising a water outlet pipe section 2 installed below an open-air floor 1, a water storage tank 3 is provided above the open-air floor 1, a water pump 4 is provided in the water storage tank 3, and water in the water storage cavity 16 in the water storage tank 3 is sent to the water outlet pipe section 2 by the water pump 4. A collection mechanism is provided above the water storage tank 3, and the collection mechanism includes a waterproof collection cylinder 5. The waterproof collection cylinder 5 is a cylindrical structure surrounded by elastic waterproof cloth with open ends at the upper and lower ends. The bottom end of the waterproof collection cylinder 5 is blocked by a base plate 6 fixed to the top of the water storage tank 3, and the base plate 6 has multiple openings. Perforations, multiple perforations are connected to the water inlet at the top of the water tank 3, and pulling links 7 are respectively provided on both sides of the outer periphery of the upper section of the waterproof collecting tube 5.

The two transition links 9 are driven by the collection drive mechanism to rotate around their respective second hinge shafts 10, and cooperate with the elastic force of the spring 11, thereby driving the waterproof collecting tube 5 to expand outward or contract inward.

[0020] Among them, the collection drive mechanism includes a collection motor 12, a bundle tube 13, two steel ropes 14, and two pull rings 15. The collection motor 12 is fixedly installed on the top of the water tank 3, and the bundle tube 13 is rotatably installed on the top of the water tank 3 and is coaxially fixedly connected to the output end of the collection motor 12. The two pull rings 15 are respectively located on the outside of the two transition links 9 and fixed on the top of the water tank 3. One end of the two steel ropes 14 is respectively connected to the outside of the two transition links 9, and the other ends of the two steel ropes 14 are respectively passed through the two pull rings 15 and then wrapped and fixed with the bundle tube 13. The bundle tube 13 is driven to rotate by the collection motor 12, thereby driving the two steel ropes 14 to be retracted and released synchronously, thereby pulling or releasing the two transition links 9, so that the two transition links 9 respectively drive the two pulling links 7 to move, thereby realizing the expansion or contraction of the waterproof collection tube 5.

[0021] A water storage cavity 16 is provided within the water storage tank 3. A first filter box 17 and a second filter box 18 are provided within the water storage cavity 16 of the water storage tank 3. The top of the first filter box 17 is open and communicates with the water inlet at the top of the water storage tank 3. The top water inlet of the second filter box 18 is communicated with the water outlet on the upper side of the first filter box 17 via a water pipe 19. The water pipe 19 is provided with a pressure relief valve 20 and a one-way valve 21. A filter screen is provided within the second filter box 18. The water outlet on one side of the second filter box 18 communicates with the water storage cavity 16 of the water storage tank 3. The first filter box 17 and the second filter box 18 are designed with an openable side door on one side to facilitate cleaning of impurities filtered inside.

[0022] A power mechanism is provided under the open-air floor 1, which includes a power box 22 installed at the bottom of the open-air floor 1. A liquid control valve 23 is provided inside the power box 22. The outlet end of the water pump 4 is connected to the inlet end of the liquid control valve 23 through a connecting water pipe 24. The top of the outlet pipe section 2 is rotatably connected to the outlet end of the liquid control valve 23. A strip groove 25 is provided at the bottom of the power box 22. The bottom end of the outlet pipe section 2 passes downward from the strip groove 25 and is provided with a nozzle 31. A swinging drive mechanism is also provided inside the power box 22 for driving the outlet pipe section 2 to swing back and forth.

[0023] The swing drive mechanism includes two groups of swing drive units relatively arranged on the left and right sides of the water outlet pipe section 2, each group of swing drive units includes a meshing gear 26 and a rack 27. The rack 27 is close to the end of the water outlet pipe section 2 and is rotatably provided with a pushing roller 28. The end of the rack 27 away from the water outlet pipe section 2 is connected to a telescopic rod 29, and the other end of the telescopic rod 29 is connected to the power box 22. The gear 26 is connected to the output end of the swing motor 30 installed on the power box 22. The gear 26 is driven to rotate by the swing motor 30, and the rotating gear 26 drives the rack 27 to move left and right. The pushing roller 28 at the end of the rack 27 pushes the water outlet pipe section 2 to swing left and right in the strip groove 25.

[0024] When rainwater needs to be collected, the collection motor 12 of the collection drive mechanism is started, and the collection motor 12 drives the bundle cylinder 13 to rotate, thereby driving the two steel ropes 14 to contract synchronously, thereby pulling the two transition links 9 outward, so that the two transition links 9 respectively rotate outward around their respective second hinge shafts 10, and the two transition links 9 respectively drive the two pulling links 7 to move outward, and the two pulling links 7 pull the two sides of the waterproof collecting cylinder 5 outward to unfold the waterproof collecting cylinder 5, increase the contact area between the waterproof collecting cylinder 5 and the rain curtain, and collect rainwater to the greatest extent. The collected rainwater is stored in the water storage tank 3, thereby solving the problem of water source difficulties.

[0025] When there is no need to collect rainwater, the collection motor 12 reverses, the two steel ropes 14 are released synchronously, the two transition links 9 are released, and the two springs 11 pull the two transition links 9 inward respectively, so that the upper ends of the two transition links 9 rotate toward the direction close to the waterproof collecting tube 5, and the two pulling links 7 move together with the upper ends of the two transition links 9 toward the direction close to the waterproof collecting tube 5, thereby converging the waterproof collecting tube 5, ensuring that when water storage is not needed, the waterproof collecting tube 5 is exposed to the sun due to its unfolding, thereby affecting the service life of the waterproof collecting tube 5.

[0026] The rainwater collected by the waterproof collection tube 5 flows into the first filter box 17 through the multiple perforations of the substrate 6, and the first sedimentation filtration is completed in the first filter box 17; when the water level in the first filter box 17 rises to the position of the water pipe 19, the water in the first filter box 17 flows into the second filter box 18 through the water pipe 19, and the water body is filtered for the second time through the filter mesh in the second filter box 18. The water after the secondary filtration flows into the water storage cavity 16 of the water tank 3 through the water outlet of the second filter box 18, completing the storage of rainwater.

[0027] When water spraying is needed to extinguish a fire, water pump 4 is activated, pumping water from water storage cavity 16 through connecting water pipe 24 into water outlet pipe section 2. Water is then sprayed out through nozzle 31 at the bottom of water outlet pipe section 2, extinguishing the fire. During this process, the two swing drive units are activated, driving the two push rollers 28 back and forth, which in turn pushes the water outlet pipe section 2 to swing left and right within the strip groove 25. This causes nozzle 31 to swing left and right to spray water, expanding the area covered by the water spraying, thereby effectively preventing the spread of the fire.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
