Description

Technical Field

[0001] The invention relates to the technical field of electric smoke exhaust, and in particular to a backpack-type hand-propelled integrated electric smoke exhaust device for fire fighting. Background Art

[0002] Fire-fighting electric smoke exhausters play a vital role in fire accidents. Their main task is to ensure the safe evacuation of personnel and reduce the harm of smoke to human health by effectively exhausting thick smoke and toxic gases. Existing fire-fighting smoke exhaust equipment usually consists of a motor, an impeller, an air inlet, an air outlet, a casing, etc., which can be quickly started by electric or manual control when a fire occurs to help exhaust high-temperature smoke and toxic gases in the room.

[0003] Although the existing electric smoke exhaust machines for fire fighting have been improved in terms of fire resistance, sealing and smoke exhaust efficiency, there are still many technical deficiencies in practical applications. First, most smoke exhaust equipment is designed for fixed installation, which is bulky and heavy, making it very inconvenient to carry and move, especially in complex or narrow environments, where it is difficult to operate flexibly. Second, the existing equipment generally lacks the folding function and cannot meet the needs of efficient storage and transportation under space-constrained conditions.

[0004] In order to deal with these problems, the market urgently needs a fire-fighting electric smoke exhaust device that is easy to carry and move and has a folding function. For example, although the portable smoke exhaust machine disclosed in CN212320002U improves the smoke exhaust efficiency through the dual-fan design, it has obvious limitations in storage and transportation because it cannot be folded. In addition, the drive motor is usually installed on the side of the fan and arranged outward. Even if the smoke exhaust machine is foldable, the drive motor will press against the body of the fan when the smoke exhaust machine is folded, thereby affecting the folding effect. In summary, there is a lack of a fire-fighting electric smoke exhaust device on the market that can effectively solve the problems of inconvenience in carrying and difficulty in folding. Summary of the invention

[0005] The problem to be solved by the present invention is that the existing electric smoke exhaust devices for fire fighting are insufficiently portable, lack a folding function and are difficult to fold, and a back-carrying and hand-pushed integrated electric smoke exhaust device for fire fighting is provided.

[0006] In order to solve the above problems, the present invention provides a back-mounted and hand-propelled integrated fire-fighting electric smoke exhaust device, comprising a fan body, a driving mechanism is provided at the inner end of the fan body, and folding support mechanisms are provided downwardly extending at both ends of the fan body, and one end of the folding support mechanism away from the fan body is fixedly connected to a control box body, and the fan body is turned upside down and opened and closed through the folding support mechanism, and a positioning clamp groove is provided at the center of the upper end of the control box body, and the driving mechanism is clamped in the positioning clamp groove.

[0007] Preferably, the driving mechanism comprises a driving motor, the driving motor is drivingly connected to the blades in the fan body, and the other end of the driving motor is electrically connected to a power source.

[0008] Preferably, the folding support mechanism includes a folding support bracket, one end of the folding support bracket is fixedly connected to a curved top plate, the curved top plate is fixedly connected to the fan body and fits against the outer edge of the fan body, the side end of the folding support bracket away from the curved top plate is fixedly provided with a connecting plate, the side end of the connecting plate is provided with a positioning substrate, and the connecting plate is movably connected to the positioning substrate via a pin shaft.

[0009] Preferably, the folding support bracket and the side ends of the control box are both provided with push components.

[0010] Preferably, the push component comprises a rotating wheel seat, in which a rotating wheel is movably hinged.

[0011] Preferably, a support rod is provided at the bottom of the control box, and an anti-skid shock-absorbing gasket is provided at the bottom of the support rod. The anti-skid shock-absorbing gasket can be made of polyurethane rubber, which provides good anti-skid and shock-absorbing effects during use, further improving the safety of equipment use, especially in an environment where the fan generates large vibrations during use. The anti-skid shock-absorbing gasket can effectively reduce the risk of equipment displacement and maintain the stability of the device during operation.

[0012] Preferably, the positioning clip groove is provided with heat dissipation holes communicating with the interior of the control box, and the heat dissipation holes are evenly distributed from left to right. By providing heat dissipation holes in the control box, the heat dissipation performance of the device during long-term operation can be effectively improved, and performance degradation or failure of the device due to overheating can be avoided. The evenly distributed heat dissipation hole design ensures smooth air circulation, thereby extending the service life of the device.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: 1. Improved portability and flexibility: The fan body of the present invention is turned upside down and opened and closed by a folding support mechanism. Through the foldable support mechanism, the device can be easily folded and unfolded, which is convenient for carrying and use in different environments. After folding, the volume of the device is greatly reduced, which is convenient for storage and transportation, and is particularly suitable for use in environments with limited space.

[0014] 2. Effectively solve the problem of folding difficulties: The present invention provides a positioning groove at the upper end of the control box, and the driving mechanism can be snapped into the positioning groove. In this way, when the device is folded, the driving mechanism will not hinder the folding of the fan body, thereby ensuring a good folding effect, thereby ensuring the folding effect.

[0015] 3. Easy operation: The present invention integrates two modes of use: carrying on the back and pushing by hand. The operator can flexibly choose the carrying or pushing mode according to the needs of the site, which greatly improves the convenience of operation. After the operator folds the device, he can carry it directly on his back or add a shoulder strap. In a narrow space, the carrying function makes the device easy to carry; after the device is folded, the operator can turn the wheels of the pushing component downward and push the device by hand. The hand-pushing function is suitable for fast movement on flat ground, which enhances the adaptability of the device.

[0016] 4. High structural stability and multifunctionality: The present invention maintains good stability during operation through the fixed connection between the folding support bracket and the fan body, and the horizontal push component of the control box, avoiding the shaking or tipping of the equipment, and ensuring the safety and reliability of operation. The present invention can not only be used for smoke exhaust under normal circumstances, but also for emergency rescue and other occasions, which increases the scope of use of the equipment and meets diverse needs.

[0028] The side ends of the folding support bracket 301 and the control box 4 are both provided with a horizontal pushing component 5 .

[0029] The horizontal pushing component 5 includes a rotating wheel seat 501 , and a rotating wheel 502 is movably hinged inside the rotating wheel seat 501 .

[0030] Reference Figure 6 As shown, a support rod 6 is provided at the bottom of the control box body 4, and an anti-skid shock-absorbing gasket 7 is provided at the bottom of the support rod 6. The anti-skid shock-absorbing gasket can be made of polyurethane rubber, which provides good anti-skid and shock-absorbing effects during use, further improving the safety of the equipment.

[0032] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are described in detail below through specific usage methods.

[0033] The present invention is a backpack-type hand-push integrated fire-fighting electric smoke exhaust device, which is designed for smoke exhaust at a fire scene. The specific working process is as follows: 1. Preparation: Before using the device, the operator needs to select the appropriate usage mode according to the on-site environment. This device provides two usage modes: backpack mode and hand-push mode. The backpack mode is suitable for use in a small space, while the hand-push mode is suitable for fast movement in a wider area.

[0034] 2. Expand the device: When the equipment is needed, the operator removes the device from the storage location.

[0035] By unlocking the folding support mechanism 3, the operator moves the connecting plate 303 to drive the folding support bracket 301 upward, and unfolds the device from the folded state. At this time, the fan body 1 is turned upside down by the folding support mechanism 3 and enters the working state.

[0036] Smoke exhaust operation: The operator selects the use mode according to the needs of the site and adjusts the position of the device. If in a narrow space, the operator can carry the device on his back; if in a more spacious environment, the operator can use the rotating wheel 502 of the horizontal push component 5 to push the device to the target position.

[0037] After the target position is determined, the drive mechanism 2 is started. The drive motor 201 is powered by the power supply 202 to drive the blades in the fan body 1 to rotate, thereby generating a strong airflow to quickly discharge the high-temperature smoke and toxic gases at the fire scene.

[0038] During the operation of the device, the heat dissipation strip holes 402 ensure that the heat in the control box 4 can be effectively dissipated, thereby preventing the device from being affected in performance or causing malfunctions due to overheating.

[0039] Movement and Adjustment: If it is necessary to adjust the position at the fire scene, the operator can use the push component 5 to quickly move the device without shutting down the device, or carry the device across obstacles through the carrying function.

[0040] In an environment with large vibrations, the anti-skid shock-absorbing washer 7 at the bottom of the support rod 6 provides anti-skid and shock-absorbing effects, ensuring that the equipment remains stable during operation and reducing safety risks caused by shaking or tipping of the equipment.

[0041] 5. Equipment storage: After the smoke exhaust task is completed, the operator stops the driving mechanism 2 and waits for the equipment to completely stop running.

[0042] By folding the support mechanism 3, the device is folded back to its original position, and the fan body 1 is turned upside down. The folded device has a smaller volume and is convenient for storage and transportation.

[0043] During the folding process, the positioning clip groove 401 on the control box body 4 ensures the stable fixation of the driving mechanism 2, preventing the driving motor 201 from hindering the folding of the fan body 1 during folding. Finally, the device is stored in the storage location of the fire fighting equipment for next use.

[0044] The hand-pushed integrated fire-fighting electric smoke exhaust device of the present invention fully considers portability, ease of operation and equipment stability, and can provide effective smoke exhaust function in complex and changeable fire scenes. Its folding structure and multiple usage modes make the device not only suitable for general fire occasions, but also for special situations such as emergency rescue.
