Description

Technical Field

[0001] This utility model relates to the field of power supply vehicle technology, specifically a mobile fire emergency power supply vehicle that can be manually and electrically retracted and deployed. Background Technology

[0002] A fire emergency mobile power supply vehicle is a mobile power supply device specifically designed to respond to fires and other emergencies. In factories, there are often sudden emergencies, such as fires, where the fire scene is in poor condition and the required power source is far away. Especially when the emergency occurs at night, the inability to find a power source or the improper configuration of temporary power sources can result in insufficient lighting for rescue personnel, which not only delays the rescue progress but also jeopardizes their own safety. Therefore, a fire emergency mobile power supply vehicle is needed to avoid such situations.

[0003] For example, patent CN220349734U discloses an emergency mobile power supply vehicle, including a frame. The frame has locking casters at the bottom for easy movement and positioning. A threaded rod on the casing rotates, causing a threaded block to rise and fall, facilitating the raising and lowering of a U-shaped plate. When the bottom of the U-shaped plate is in contact with the ground, the emergency power supply can be directly pushed onto it, simplifying placement and avoiding the need for manual lifting, thus improving replacement efficiency. Slopes (not shown in the diagram) are provided on both sides of the U-shaped plate, with the slope angle adjustable according to actual conditions. These slopes further enhance the ease of placing the emergency power supply. However, during use, the emergency power supply can only connect to lighting equipment. In emergency accident scenes, where the area is large and cable lengths vary, a mobile power supply may be available, but the cable length may be insufficient to illuminate more areas.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing mobile power supply vehicles for fire emergencies. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile emergency power supply vehicle for fire fighting that can be manually and electrically retracted and deployed, in order to solve the problem mentioned in the background art that, due to the large area of ​​some accident sites and the differences in cable lengths, there may be situations where the mobile power supply is available but the cable length is insufficient, resulting in the inability to illuminate more areas.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a manually and electrically operated fire emergency mobile power supply vehicle with reel and lay, comprising a mobile frame, a box mounted on one side of the top of the mobile frame, a box cover provided on the top of the box, and support frames fixedly connected to both sides of the top of the mobile frame; a rotating shaft rotatably connected inside the support frame, a coil mounted on the rotating shaft, and a support arm mounted on one side of the support frame; and a drive mechanism for driving the coil to rotate is provided on the mobile frame.

[0007] Furthermore, the drive mechanism includes a drive motor, which is mounted on one side of the mobile frame. A rotating handle is movably connected to one end of the rotating shaft. Both the output end of the drive motor and one end of the rotating shaft are equipped with transmission pulleys, and a transmission belt is provided between the two transmission pulleys.

[0008] Furthermore, the support arm is provided with an anti-winding mechanism to prevent the coil from tangling.

[0009] Furthermore, the anti-winding mechanism includes a rotating drum, the two ends of which are rotatably connected between two support arms via a drive shaft. An arc-shaped groove is formed on the rotating drum, and a guide block is slidably connected inside the arc-shaped groove. A guide wheel is rotatably connected to the top of the guide block, and a connecting rod is rotatably connected inside the guide wheel. The two ends of the connecting rod are fixedly connected to the support arms via brackets. A first drive gear is mounted on the drive shaft of the rotating drum, and a rotating column is also mounted on the support arm. Synchronous pulleys are mounted on the outer wall of the rotating column and the outer wall of the rotating shaft. A synchronous belt is provided between the two synchronous pulleys. A second drive gear is mounted on the rotating column, and the first drive gear and the second drive gear mesh with each other.

[0010] Furthermore, a row of temporary power connection areas is provided on one side of the box cover, an electric cable release button and an electric cable retraction button are provided on the top of the box cover, and a pluggable power plug is provided on one side of the box cover.

[0011] Furthermore, the lid and the body of the box are connected by a threaded rod.

[0012] Furthermore, a handle is installed on one side of the mobile frame.

[0013] Furthermore, the diameter of the first transmission gear is larger than the diameter of the second transmission gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This manually and electrically operated fire emergency mobile power supply vehicle allows operators to easily and quickly reel in or unelevate cables under normal circumstances by pressing either the electric cable release button or the electric cable reel button, making operation simple and efficient. In case of a drive motor malfunction or other special circumstances, the cable reel can be manually rotated using a handle to complete the cable reeling and unelevation. This dual-mode design provides the power supply vehicle with great flexibility and emergency backup, ensuring smooth cable reeling and unelevation operations in various situations, while also addressing the issue of insufficient cable length in emergency locations.

[0016] Furthermore, as the rotating shaft rotates, the synchronous pulley, synchronous belt, and the first and second transmission gears work together to drive the rotating drum to rotate, which in turn causes the guide block to reciprocate within the arc-shaped groove, driving the guide wheel to also reciprocate. This design guides the cable to be evenly wound on the reel, preventing cable from piling up and tangling during both take-up and unwinding processes. This ensures orderly cable handling, improves work efficiency, and reduces potential malfunctions and safety hazards caused by cable tangling.

[0017] Furthermore, the temporary power connection area set on one side of the cover provides an interface for connecting power to temporary electrical equipment at the fire emergency site, making it convenient for various electrical equipment on site to obtain power in a timely manner, meeting the diverse power needs in fire emergency scenarios, and enhancing the practicality of the power supply vehicle.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Example 1: Please refer to Figures 1-7 This utility model provides the following technical solution: a mobile emergency power supply vehicle for fire fighting that can be manually and electrically retracted and deployed, including a mobile frame 1, a box 2 installed on one side of the top of the mobile frame 1, a box cover 3 on the top of the box 2, and support frames 4 fixedly connected to both sides of the top of the mobile frame 1; a rotating shaft 5 is rotatably connected inside the support frame 4, a coil 6 is installed on the rotating shaft 5, and a support arm 10 is installed on one side of the support frame 4; a drive mechanism for driving the coil 6 to rotate is provided on the mobile frame 1; the drive mechanism includes a drive motor 8, which is installed on one side of the mobile frame 1, a rotating handle 7 is movably sleeved on one end of the rotating shaft 5, and a transmission pulley 9 is installed on both the output end of the drive motor 8 and one end of the rotating shaft 5, with a transmission belt between the two transmission pulleys 9.

[0028] In use, the mobile frame 1 can be moved via the handle for quick deployment in fire emergency scenarios. When electric cable reeling or unloading is required, the operator presses the electric unloading button 16 or electric reeling button 21 on the cover 3 to start the drive motor 8. The output end of the drive motor 8 is connected to the transmission pulley 9, allowing the drive motor 8 to drive the transmission pulley 9 to rotate. This, in turn, drives the transmission pulley 9 on the rotating shaft 5 to rotate via the transmission belt, which in turn drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 causes the reel 6 mounted on it to rotate as well, releasing the cable from the reel 6. Similarly, pressing the electric reeling button 21 reverses the drive motor 8, causing the reel 6 to rotate in the opposite direction to reel in the cable. When the drive motor 8 malfunctions or manual operation is required in certain special circumstances, the operator can hold the rotating handle 7. The rotating handle 7 is movably sleeved on one end of the rotating shaft 5. By manually rotating the rotating handle 7, the operator directly drives the rotating shaft 5 to rotate, which in turn causes the reel 6 to rotate, thus reeling in or unloading the cable. This manual mode provides emergency protection for the operation of the power supply vehicle.

[0029] Example 2: Based on Example 1, an anti-winding mechanism is also disclosed, the specific structure of which is as follows:

[0030] The anti-winding mechanism includes a rotating drum 11, with both ends of the drum 11 rotatably connected between two support arms 10 via a drive shaft. An arc-shaped groove 12 is formed on the rotating drum 11, and a guide block 19 is slidably connected inside the arc-shaped groove 12. A guide wheel 20 is rotatably connected to the top of the guide block 19, and a connecting rod 13 is rotatably connected inside the guide wheel 20. Both ends of the connecting rod 13 are fixedly connected to the support arms 10 via brackets. A first transmission gear 23 is mounted on the drive shaft of the rotating drum 11. A rotating column is also mounted on the support arm 10, and both the outer wall of the rotating column and the outer wall of the rotating shaft 5 are fitted with… Synchronous pulley 14, a synchronous belt is provided between the two synchronous pulleys 14, a second transmission gear 22 is installed on the rotating column, and the first transmission gear 23 meshes with the second transmission gear 22; a row of temporary power connection area 15 is provided on one side of the box cover 3, an electric cable release button 16 and an electric cable retraction button 21 are provided on the top of the box cover 3, and a pluggable power plug 17 is provided on one side of the box cover 3; the box cover 3 is connected to the box body 2 by a threaded rod 18; a handle is installed on one side of the mobile frame 1; the diameter of the first transmission gear 23 is larger than the diameter of the second transmission gear 22.

[0031] When the rotating shaft 5 rotates, the synchronous wheel 14 installed on the rotating shaft 5 rotates accordingly. Through the set synchronous belt, the synchronous wheel 14 on the rotating shaft 5 transmits power to the synchronous wheel 14 on the rotating column, causing the rotating column to rotate. After the rotating column rotates, it drives the second transmission gear 22 on it to rotate. Because the second transmission gear 22 meshes with the first transmission gear 23, the rotation of the second transmission gear 22 will drive the first transmission gear 23 to rotate, thereby driving the rotating drum 11 to rotate. During the winding and unwinding process, the cable is guided by the guide wheel 20. The rotating drum 11 has an arc groove 12. The guide block 19 slides in the arc groove 12. The rotating drum 11 rotates under the drive of the rotating shaft 5, so the guide block 19 reciprocates under the restriction of the arc groove 12. The top of the guide block 19 is rotatably connected to the guide wheel 20, so the guide wheel 20 also reciprocates with the guide block 19. The reciprocating motion of the guide wheel 20 can guide the cable to be evenly wound on the reel 6. When the reel 6 rotates to reel in the cable, the guide wheel 20 moves left and right continuously, arranging the cable sequentially on the reel 6 to prevent it from piling up and tangling. Similarly, during cable release, the guide wheel 20 ensures the cable is smoothly released from the reel 6, preventing tangling. The temporary power connection area 15 on one side of the cover 3 provides a power interface for temporary electrical equipment in fire emergency situations. Pressing the electric cable release button 16 causes the drive motor 8 to rotate forward, and the reel 6 begins releasing the cable. Pressing the electric cable reel button 21 causes the drive motor 8 to rotate in reverse, and the reel 6 begins reeling in the cable. Operators can conveniently control the cable release and reeling according to actual needs. When it is necessary to open the enclosure 2 for equipment maintenance, inspection, or to retrieve items, the operator can rotate the threaded rod 18 to loosen the connection between the threaded rod 18 and the enclosure 2 or cover 3, thereby opening the cover 3. When it is necessary to close the enclosure 2, the threaded rod 18 is rotated in the opposite direction to ensure a tight fit between the cover 3 and the enclosure 2, preventing accidental opening of the cover 3 during movement and protecting the equipment inside the enclosure 2.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
