Technical Field
[0001] This utility model relates to the field of fire extinguishing device technology, and in particular to an indoor emergency fire extinguishing device for building construction. Background Technology
[0002] During construction, the presence of numerous flammable materials and the use of open flames and electrical equipment create a high risk of fire. In the event of a fire, traditional firefighting methods, such as manual fire extinguishers or fixed fire suppression systems, may have limitations in extinguishing range and response time, making it difficult to effectively control the spread of fire and leading to significant losses during construction. Furthermore, ordinary water-based extinguishing agents are not very efficient at extinguishing certain types of fires, especially against rapidly burning materials, as their penetration and adhesion are insufficient to quickly suppress flames. To address these issues, an indoor emergency fire extinguishing device for construction sites has been designed. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an indoor emergency fire extinguishing device for building construction.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: an indoor emergency fire extinguishing device for building construction, comprising a base and a water tank, wherein a reciprocating water spraying mechanism for performing continuous up-and-down sequential water spraying fire extinguishing operation is installed on the base;
[0005] The reciprocating water spraying mechanism includes a motor, which is fixedly connected to the base. A drive shaft is fixedly connected to the output end of the motor. A double-groove pulley is fixedly connected through the drive shaft. The double grooves on the double-groove pulley are meshed with driven pulleys via a transmission belt. There are two sets of driven pulleys, located at the left and right ends of the double-groove pulley respectively. Support frames are fixedly connected to the left and right sides of the base. The driven pulleys are rotatably connected to the support frames. A connecting shaft is eccentrically fixed to the driven pulleys. A drive linkage is hinged to the connecting shaft. A rack is hinged to the end of the drive linkage away from the connecting shaft, and a gear meshes with the rack. A driven shaft is fixedly connected through the gear. The driven shaft is rotatably connected to the support frame. A water supply pipe is fixedly connected to the end of the driven shaft away from the gear. The end of the water supply pipe away from the driven shaft is rotatably connected to the other end of the support frame. A spray nozzle for water spraying is installed on the water supply pipe.
[0006] As a further description of the above technical solution:
[0007] The support frame is provided with a sliding groove, and the sliding groove limits and guides the movement of the rack through an internal sliding rod. At the same time, the end of the sliding rod away from the sliding groove is fixed to the rack.
[0008] As a further description of the above technical solution:
[0009] The drive shaft is equipped with a stirring mechanism for mixing water and inactivated materials. The stirring mechanism includes a stirring rod, which is fixed to the drive shaft. The end of the stirring rod away from the drive shaft rotates through the water tank. The stirring rod is equipped with stirring blades for stirring the liquid in the water tank.
[0010] As a further description of the above technical solution:
[0011] A limiting plate for limiting the rotation of the stirring rod is fixedly connected to the base, and the limiting plate is rotatably connected to the stirring rod.
[0012] As a further description of the above technical solution:
[0013] The water tank is fixedly connected to a support leg, and a material box for storing drag-reducing agent is fixedly connected to the end of the support leg away from the water tank.

[0016] This utility model has the following beneficial effects:
[0017] 1. In this utility model, the motor drives the belt transmission assembly to rotate, which in turn drives the connecting shaft to rotate. The rotation of the connecting shaft causes the drive linkage to drive the rack to move up and down reciprocally. The rack drives the gear to rotate up and down, and the gear drives the water pipe to swing up and down continuously through the driven shaft. In turn, the water pipe drives the nozzle to spray water into the interior of the burning building in a continuous up and down sequence, thereby expanding the fire extinguishing range, shortening the fire extinguishing time, improving the fire extinguishing efficiency, and reducing the cost of damage caused by fire during building construction.
[0018] 2. In this utility model, the baffle plate is opened by controlling the agent box and the electric push rod, and the drag-reducing agent is added to the water tank through the feed hole. Then, the stirring rod and stirring blade can stir and mix the water and drag-reducing agent in the water tank, so that the water can more easily adhere to the surface of the burning material, improve the application efficiency and penetration ability of the water, and is very effective for extinguishing fires inside buildings.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1: Please refer to Figure 1-6 An embodiment of this utility model is provided: an indoor emergency fire extinguishing device for building construction, including a base 1 and a water tank 4. A reciprocating water spraying mechanism 2 for continuous up-and-down water spraying fire extinguishing operation is installed on the base 1.
[0029] The reciprocating water spray mechanism 2 includes a motor 21, which is fixedly connected to the base 1. A drive shaft 22 is fixedly connected to the output end of the motor 21. A double-groove pulley 23 is fixedly connected through the drive shaft 22. The double grooves on the double-groove pulley 23 are meshed with driven pulleys 24 via a transmission belt.

[0030] Working principle: First, in the event of a fire during construction, the electric actuator 7 can be activated. The retracting end of the electric actuator 7 retracts, causing the baffle plate 8 to open on the agent box 6, allowing the drag-reducing agent to be added into the water tank 4 through the feed hole 9. Then, the motor 21 is activated. The output end of the motor 21 drives the drive shaft 22 to rotate, which in turn drives the stirring rod 31 to rotate. The stirring rod 31 then drives the stirring blade 32 to rotate, mixing the drag-reducing agent and water in the water tank 4. Simultaneously, the drive shaft 22 rotates, causing the double-groove pulley 23 to rotate. The rotation of the double-groove pulley 23 drives the driven pulleys 24 on both sides to rotate via the transmission belt. 4. Rotation drives the connecting shaft 26 to rotate. The rotation of the connecting shaft 26 causes the drive linkage 27 to drive the rack 28 to move up and down reciprocally. The rack 28 drives the gear 29 to rotate back and forth. The gear 29 drives the water supply pipe 211 to swing up and down continuously through the booster water pump 10. The swinging of the water supply pipe 211 drives the nozzle 212 to swing up and down. After the water tank 4 is stirred, the booster water pump 10 is started. The output end of the booster water pump 10 draws the mixed liquid in the water tank 4 into the water supply pipe 211 through the three-way pipe 11, so that the nozzle 212 can continuously spray water up and down into the interior of the burning building, expanding the fire extinguishing range, shortening the fire extinguishing time, and improving the fire extinguishing efficiency.
[0031] In a preferred embodiment, the support frame 25 is provided with a slide groove 213, and the slide groove 213 limits and guides the movement of the rack 28 through the internal sliding rod 214, while the end of the sliding rod 214 away from the slide groove 213 is fixed to the rack 28.
