Description

Technical Field

[0001] This utility model belongs to the field of fire pot installation technology, and in particular relates to a fire pot anti-fall structure based on a drone. Background Technology

[0002] "Fire Pot Performance" is a visual art form that combines traditional skills with modern stage effects. Its core lies in creating an immersive performance that is both dangerous and beautiful by manipulating physical phenomena such as flames and steaming hot water, in conjunction with musical rhythms and body language. To enhance the performance effect, fire pots are usually mounted on drones and performed at high altitudes.

[0003] However, traditional fire pots are usually mounted on a rotating shaft of a steel frame, which is then connected to the drone via steel cables. Since the fire pot needs to be able to rotate on the steel frame, it is usually fixed to the rotating shaft with screws. Due to the rotation, the fire pot is prone to falling during the performance, which not only affects the performance effect but also poses a serious safety hazard to the crowd. In addition, falling can also cause the drone to become unstable, seriously affecting its stability. Utility Model Content

[0004] The purpose of this invention is to provide a drone-based anti-falling kettle structure. By setting up an anti-falling mechanism, specifically, the kettle is connected to a hexagonal protrusion via a sleeve shaft, and then a fastening bolt is tightened to secure the sleeve shaft and hexagonal protrusion. A long bolt is then inserted into the sleeve shaft and its insertion hole, passing through both the sleeve shaft and the detachable rotating shaft. Finally, a nut is installed at the end of the long bolt. This prevents the kettle from falling, ensuring a more stable installation and solving the problem of kettles easily falling during performances due to rotation, which not only affects the performance but also poses a serious safety hazard to the audience.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a fall-proof fire pot structure based on a drone, comprising a steel frame, a baffle fixedly connected to the top of the steel frame, a base fixedly connected to the bottom of the steel frame, a reduction motor installed at the center of the top of the steel frame, a detachable rotating shaft mounted on the output end of the reduction motor via a coupling, and a fire pot disposed at the end of the detachable rotating shaft, and further comprising:

[0007] An anti-drop mechanism is provided at the end of the kettle. The anti-drop mechanism includes a sleeve shaft fixedly connected to the kettle. The sleeve shaft has a hexagonal groove inside. A hexagonal protrusion is fixedly connected to the side of the reduction motor facing the kettle. An insertion hole is provided at the end of the detachable rotating shaft. Several fastening bolts are threaded on the sleeve shaft. A long bolt is inserted into the sleeve shaft. The long bolt is inserted into the detachable rotating shaft through the insertion hole.

[0008] The long bolt passes through the sleeve shaft and the detachable rotating shaft, and a nut is threaded on the outside of the long bolt. The long bolt is used to connect the sleeve shaft and the detachable rotating shaft.

[0009] Furthermore, the hexagonal protrusion is inserted into the sleeve shaft through a hexagonal groove, and the end of the fastening bolt contacts the surface of the hexagonal protrusion. After the hexagonal protrusion is inserted into the sleeve shaft, it is used to position the insertion hole and the long rod bolt. With the cooperation of the hexagonal groove and the hexagonal protrusion, the detachable rotating shaft can drive the kettle to rotate more stably, avoiding slippage.

[0010] Furthermore, a cover plate is inserted into the side of the kettle away from the detachable pivot. Several inclined blocks are fixedly connected to the outer side of the cover plate. A retaining ring is fixedly connected to the side of the cover plate facing the kettle. The cover plate is inserted into the kettle through the retaining ring. The outer end of the kettle is provided with a convex ring. A pressing block is provided on the outer side of the inclined blocks. A threaded knob is threadedly connected inside the pressing block. The threaded knob is rotatably connected to the convex ring on the kettle. A limit rod is fixedly connected to the pressing block. The limit rod is slidably connected to the convex ring on the kettle. The limit rod is used to limit the pressing block, so that the pressing block moves in a straight line. The contact position between the threaded knob and the kettle is restricted, so that the threaded knob will not disengage.

[0011] The pressing block and the inclined block work together to fasten the cover plate to the kettle, and the insert ring is used to support the cover plate during installation.

[0012] Furthermore, the inclined block is set with an inclined surface on the side facing the extrusion block, the extrusion block is set with an L-shape, and the inclined surface on the inclined block is set with an inclined surface on the side facing the inclined block. When the extrusion block contacts the inclined surface of the inclined block, it will push and squeeze the inclined block, so that the cover plate is tightly fixed to the kettle.

[0013] Furthermore, a bearing seat is fixedly connected to the end of the steel frame, and the detachable rotating shaft passes through the bearing seat and extends to the outside. The bearing seat is rotatably connected to the detachable rotating shaft through a bearing. The bearing seat is used to support the detachable rotating shaft, making it more stable during rotation.

[0014] Furthermore, a power supply and a geared motor power adapter are installed inside the base, and a remote control power plug is installed on the front of the power supply; the power supply is used to supply power to the geared motor power adapter and the geared motor, and the geared motor is started by remote control to drive the detachable rotating shaft to rotate.

[0015] Furthermore, a protective mechanism is provided on the outer side of the baffle. The protective mechanism includes a protective shell that is positioned and installed on the outer side of the baffle. A square groove is opened on the top of the protective shell. A positioning protrusion is fixedly connected to the outer side of the baffle. The protective shell is positioned and inserted into the positioning protrusion through the square groove. The protective shell is fixedly connected to the baffle by screws. The protective shell is positioned and installed by the positioning protrusion and fixed by screws. By removing the screws, the protective shell can be removed for convenient subsequent maintenance.

[0016] Furthermore, a lifting ring is threadedly connected to the top of the shield, and the lifting ring is connected to a steel wire rope via a hook. The protective shell is used to protect the inside of the base. Support legs one are fixedly connected to each of the four corners of the bottom of the base, and support legs two are fixedly connected to both ends of the bottom of the steel frame. The bottoms of support legs one and support legs two are on the same horizontal plane. Support legs one and support legs two are used to support the steel frame, and the setting of support legs one and support legs two can improve the stability of the support.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting an anti-fall-off mechanism, specifically involves inserting the kettle into the hexagonal protrusion via a sleeve shaft, then tightening the fastening bolt to lock and fix the sleeve shaft and the hexagonal protrusion. Subsequently, a long bolt is inserted into the sleeve shaft and into the insertion hole, so that the long bolt passes through the sleeve shaft and the detachable rotating shaft. Finally, a nut is installed on the end of the long bolt, which can prevent the kettle from falling off and make the kettle more stable to be installed.
