Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, and more specifically, it relates to a fire extinguishing device for fire protection in construction projects. Background Technology

[0002] Construction sites contain numerous flammable sources of risk, such as construction materials like timber and bamboo plywood, volatile flammable liquids like paint and thinner, and equipment that can easily cause electrical fires, such as temporary power lines and steel bar processing machinery. Wheeled fire extinguishers, with their large capacity, long spray distance, and long extinguishing duration, can effectively extinguish large initial fires and curb the spread of fire. They are an important manual fire-fighting facility for ensuring fire prevention and control during the construction phase of construction projects. Existing wheeled fire extinguishers generally consist of a fire extinguisher tank, a spray pipe, and a wheelbarrow.

[0003] Existing application number: CN202223210446.6, this utility model discloses a wheeled fire extinguisher, including a tank, a fixed base at the lower end of the tank, a fixed base plate at the lower end of the fixed base, a connecting rod at the lower end of the fixed base plate, a stainless steel spring at the lower end of the connecting rod, a silicone base at the lower end of the stainless steel spring, a protective shell at the middle position of the lower end of the connecting rod, a fixed outer frame fitted onto the outer wall of the tank, a semi-circular groove at the inner wall of the fixed outer frame, and spring buckles at the upper positions of the left and right ends of the connecting rod. When the wheeled extinguisher is moved to the designated position, the silicone base will contact the ground first when the wheeled extinguisher is placed. The stainless steel spring and connecting rod at the upper end of the silicone base can reduce the impact force during placement, thereby protecting the tank from damage.

[0004] Based on the above, at construction sites, the ground is often uneven and temporary. When a fire breaks out and wheeled fire extinguishers are moved, the equipment is easily affected by the road conditions, resulting in continuous bumps and vibrations. The fixing structure of the spray pipe of wheeled fire extinguishers is often a simple double-wrap frame design, which is prone to gradually loosening and falling off the wrap frame under continuous bumps and vibrations. This problem may not only cause damage to the spray pipe, but also delay the initial fire fighting operation and make it difficult to respond quickly to the initial fire handling needs in case of an emergency, as it is necessary to tidy up the loose spray pipe or find the detached spray pipe. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a fire extinguishing device for construction projects. This addresses the issue that existing fire extinguishers used in construction sites often have uneven, temporary surfaces. When a fire occurs and a wheeled fire extinguisher is moved, the equipment is easily affected by the road conditions, resulting in continuous bumps and vibrations. Furthermore, the nozzle fixing structure of wheeled fire extinguishers is often a simple double-wrap frame design, which is prone to loosening and detaching from the wrapping frame during continuous bumps and vibrations. This problem not only potentially causes damage to the nozzle but also delays initial fire suppression operations and hinders rapid response to initial fire situations, as additional adjustments to loose nozzles or retrieval of detached nozzles are required in emergency situations.

[0006] The purpose and effectiveness of this utility model for fire extinguishing devices used in construction projects are achieved through the following specific technical means: A fire extinguishing device for construction projects includes a trolley, a fire extinguisher body, a spray pipe, a fixing plate, a fixing wrapping frame, a transmission box, an anti-fall-off component, and an anti-tipping component. The fire extinguisher body is fixedly connected inside the trolley. The top right side of the spray pipe is fixedly connected above the fire extinguisher body. The fixing plate is fixedly connected to the front of the trolley. The fixing wrapping frame is fixedly connected to the bottom front of the fixing plate. The transmission box is fixedly connected to the right side of the fixing plate. The anti-fall-off component is disposed inside the fixing plate. Two sets of anti-tipping components are provided, with the two sets of anti-tipping components respectively disposed at the top and bottom of the trolley.

[0007] Furthermore, the anti-detachment component includes: a sliding winding frame and a follower rack; the rear end of the sliding winding frame is slidably connected inside the fixed plate; the follower rack is fixedly connected to the right end of the sliding winding frame.

[0008] Furthermore, the anti-fall-off component also includes: a first drive shaft and a drive gear; the first drive shaft is rotatably connected inside the drive box; the drive gear is coaxially and fixedly connected to the outside of the first drive shaft.

[0009] Furthermore, the anti-detachment component also includes: a limiting ratchet and a limiting pawl; the limiting ratchet is coaxially fixedly connected to the front end of the first transmission shaft; the limiting pawl is rotatably connected inside the transmission box, and the limiting pawl meshes with the limiting ratchet.

[0010] Furthermore, the anti-detachment component also includes: a reset spring and a spiral spring; the bottom of the reset spring is fixedly connected to the upper right end of the limiting pawl, and the top of the reset spring is fixedly connected to the inside of the transmission box; the inner end of the spiral spring is fixedly connected to the outside of the first transmission shaft, and the outer end of the spiral spring is fixedly connected to the inside of the transmission box.

[0011] Furthermore, the anti-tipping assembly includes: a connecting ring, a U-shaped component, and a locking bolt; the connecting ring is sleeved on the outer side of the top of the trolley; the U-shaped component is rotatably connected to the rear of the connecting ring; and the locking bolt is inserted into the U-shaped component.

[0012] Compared with the prior art, the present invention has the following beneficial effects: Firstly, by adjusting the height of the sliding wrapping frame and using the one-way locking function of the ratchet and pawl, the spray nozzle can be tightly wrapped around the outside of both the fixed and sliding wrapping frames. Even when the trolley is bumpy or vibrating, the spray nozzle will not loosen or fall off. At the same time, when extinguishing a fire, simply moving the limiting pawl to disengage it allows the sliding wrapping frame to fall quickly, enabling the spray nozzle to deploy rapidly without the need for manual adjustment. This significantly shortens the initial fire response time and ensures the convenience and timeliness of fire extinguishing operations.

[0013] Secondly, during firefighting, the U-shaped clip can be attached to fixed external objects such as scaffolding and tightened with locking bolts to achieve a temporary and stable connection between the cart and the external object. This effectively prevents the cart from tipping over and avoids the equipment tipping over due to dragging the spray pipe, which would affect the normal use of the fire extinguisher body and provide a reliable guarantee for the smooth conduct of firefighting operations.

[0014] This invention utilizes the height adjustment function of the sliding winding frame to ensure that the spray pipe is tightly wound around the outside of both the fixed and sliding winding frames without loosening or falling off during vibrations. During firefighting, the sliding winding frame can be quickly lowered by pulling the limiting pawl to unfold the spray pipe. At the same time, the U-shaped component secures scaffolding and other external fixed objects to prevent the cart from tipping over during firefighting, ensuring convenient, timely, and smooth firefighting operations. It is precisely suited to the actual scenarios of construction sites with many rugged roads and complex terrain, effectively avoiding the two key problems that affect firefighting efficiency: spray pipe detachment and cart tipping over. This further enhances its adaptability and reliability in fire prevention and control in construction projects. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example 1: As attached Figure 1 To be continued Figure 6 As shown: This utility model provides a fire extinguishing device for construction projects, including a trolley 1, a fire extinguisher body 2, a spray pipe 3, a fixing plate 4, a fixing wrapping frame 401, a transmission box 402, and an anti-fall-off component; the fire extinguisher body 2 is fixedly connected inside the trolley 1; the top right side of the spray pipe 3 is fixedly connected above the fire extinguisher body 2; the fixing plate 4 is fixedly connected to the front of the trolley 1; the fixing wrapping frame 401 is fixedly connected to the bottom front of the fixing plate 4; the transmission box 402 is fixedly connected to the right side of the fixing plate 4; and the anti-fall-off component is disposed inside the fixing plate 4.

[0024] The anti-detachment component includes: a sliding winding frame 5 and a follower rack 501; the rear end of the sliding winding frame 5 is slidably connected inside the fixed plate 4; the follower rack 501 is fixedly connected to the right end of the sliding winding frame 5.

[0025] The anti-fall-off component also includes: a first drive shaft 6 and a drive gear 601; the first drive shaft 6 is rotatably connected inside the drive box 402; the drive gear 601 is coaxially fixedly connected to the outside of the first drive shaft 6.

[0026] The anti-drop component also includes: a limiting ratchet 602 and a limiting pawl 7; the limiting ratchet 602 is coaxially fixedly connected to the front end of the first transmission shaft 6; the limiting pawl 7 is rotatably connected inside the transmission box 402, and the limiting pawl 7 meshes with the limiting ratchet 602.

[0027] The anti-drop component also includes: a reset spring 701 and a spiral spring 603; the bottom of the reset spring 701 is fixedly connected to the upper right end of the limiting pawl 7, and the top of the reset spring 701 is fixedly connected to the inside of the transmission box 402; the inner end of the spiral spring 603 is fixedly connected to the outside of the first transmission shaft 6, and the outer end of the spiral spring 603 is fixedly connected to the inside of the transmission box 402.

[0028] The specific usage and function of this embodiment are as follows: In use, the injection pipe 3 is first wound around the outside of the fixed winding frame 401 and the sliding winding frame 5. After winding, the winding frame 5 is slid upwards, widening the gap between the fixed winding frame 401 and the sliding winding frame 5. This allows the injection pipe 3 to be tightly wound around the outside of the fixed winding frame 401 and the sliding winding frame 5. During this process, the upward movement of the sliding winding frame 5 drives the first transmission shaft 6 to rotate clockwise via a gear and rack transmission mechanism consisting of a follower rack 501 and a transmission gear 601. However, under the action of a ratchet and pawl transmission mechanism consisting of a limiting ratchet 602 and a limiting pawl 7, the first transmission shaft 6 can only rotate clockwise. This ensures that the upward-moving sliding winding frame 5 remains at its current height and does not descend, allowing the injection pipe 3 to be tightly wound around the outside for an extended period. When a fire occurs and the trolley 1 is moved quickly across the uneven ground of the construction site, the spray pipe 3 will not fall off the outer side of the fixed winding frame 401 and the sliding winding frame 5. After arriving at the fire scene, simply pull up the right end of the limiting pawl 7 to disengage the limiting ratchet 602 and the limiting pawl 7. Under the rebound action of the spiral spring 603, the first drive shaft 6 rotates counterclockwise, causing the sliding winding frame 5 to fall quickly, reducing the distance between it and the fixed winding frame 401. This allows the spray pipe 3 wrapped around the outer side of the fixed winding frame 401 and the sliding winding frame 5 to be quickly removed and unfolded, facilitating rapid fire extinguishing. After releasing the right end of the limiting pawl 7, under the rebound action of the return spring 701, the limiting pawl 7 and the limiting ratchet 602 re-engage, making it easy to reuse.

[0029] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, it also includes anti-tipping components. Two sets of anti-tipping components are set at the top and bottom of the trolley 1, respectively.

[0030] The anti-tipping component includes: a connecting ring 8, a U-shaped part 801, and a locking bolt 9; the connecting ring 8 is sleeved on the outer side of the top of the trolley 1; the U-shaped part 801 is rotatably connected to the rear of the connecting ring 8; and the locking bolt 9 is inserted into the U-shaped part 801.

[0031] The specific usage and function of this embodiment are as follows: Upon arrival at the fire scene, if the terrain is complex and there is concern that the cart 1 may tip over during the dragging of the spray nozzle 3, affecting the use of the fire extinguisher body 2, nearby scaffolding or other objects can be found. The nut of the locking bolt 9 can be unscrewed and pulled out from the U-shaped part 801. The U-shaped part 801 can then be inserted into the outside of the scaffolding. The locking bolt 9 can then be reinserted into the U-shaped part 801 and the nut tightened. This temporarily connects the cart 1 to the external object, preventing the cart 1 from tipping over during the dragging of the spray nozzle 3. U-shaped parts 801 are provided on the inner sides of the two rollers at the top and bottom of the cart 1, adapting to more usage sites. If both U-shaped parts 801 are connected to the outside, the connection stability of the cart 1 can be further improved.
