Description

Technical Field

[0001] This utility model relates to the field of fire rescue auxiliary tools technology, and in particular to a novel honeycomb removal device. Background Technology

[0002] Wasps, scientifically known as Vespa nidus, are a subgroup of insects belonging to the order Hymenoptera. They are widely distributed and highly venomous; their stings contain phospholipase, hyaluronidase, and a protein called antigen 5. A wasp sting causes immediate redness, swelling, and a burning pain, and in severe cases, can be fatal. Analysis of wasp nest response data from a fire and rescue brigade from 2019 to 2023 shows that the peak response period is from June to August each year. Nowadays, wasps, originally from rural areas, are increasingly appearing in well-maintained urban parks and green spaces, even brazenly establishing their nests on balconies, under windows, and under eaves of urban homes. During wasp nest removal, inadequate or insufficient protection, excessively close perimeters, or improper handling can lead to swarm attacks by wasps, causing serious injury to rescue personnel.

[0003] Therefore, how to quickly and safely dispose of wasp nests and reduce rescue risks becomes particularly important. Existing methods for disposing of wasp nests mainly include bagging, fire attack, water attack, and pesticide spraying. To efficiently dispose of wasp nests, a utility model patent with patent number 201720065874.4, entitled "A Wasp Nest Removal Device and Wasp Nest Processing System," provides an auxiliary device for wasp nest disposal. This device uses a deformable support frame to support a net bag, allowing its opening to form any shape, facilitating the capture of wasp nests in various environmental locations. During the tightening process, a one-way tightening component ensures the drawstring tightens in one direction, preventing rebound and avoiding the escape of wasps already removed from the net bag. An automatic drawstring assembly uses a spring to automatically and quickly tighten the drawstring. Furthermore, the wasp nest processing system includes a wasp nest baking device and / or a wasp nest removal device. The wasp nest baking device includes a flame-spraying component and a remote ignition component, which can quickly ignite the flame and burn the wasp nest. The wasp nest removal device includes multiple tools with different structures; any tool can be selected and fixed to the baking rod for removal of the wasp nest. The honeycomb baking device, honeycomb removal device, and honeycomb harvesting device work together to effectively handle honeycomb nests. This utility model has a reasonable structure and simple operation, effectively handling honeycomb nests and preventing injury to rescuers and others. However, in actual use, the bottom of the baking rod of the honeycomb harvesting system is prone to bending, leading to unstable gas supply when igniting the wasp nest. Rescuers need to hold the baking rod with one hand and straighten the bent area with the other to ensure gas supply, which is very inconvenient. Furthermore, prolonged operation can lead to significant physical exertion for rescuers, increasing the risk of the baking rod tipping over or even disturbing the wasps, potentially triggering a swarm attack and endangering the rescuers. Utility Model Content

[0004] The features and advantages of this invention are set forth in part in the description which follows, or may be apparent from the description, or may be learned by practice of this invention.

[0005] To overcome the problems of the existing technology, the purpose of this utility model is to provide a novel honeycomb removal device.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A novel honeycomb removal device includes a multi-stage telescopic rod with a hollow center, a gas pipe located inside the telescopic rod, an ignition mechanism connected to the gas pipe and detachably mounted on the top of the telescopic rod, an anti-bending base located at the bottom of the telescopic rod with a through hole in the middle to facilitate the passage of the gas pipe, and a multi-functional knife detachably mounted on the top of the telescopic rod; the multi-functional knife is T-shaped; the multi-functional knife includes a handle detachably connected to the telescopic rod and a double-edged blade located on the top of the handle.

[0008] Preferably, the anti-bending base includes a circular tube whose top is connected to the bottom of the telescopic rod, and at least one U-shaped hole at the bottom of the circular tube; the diameter of the U-shaped hole is larger than the diameter of the gas pipe.

[0009] Preferably, the double-edged blade includes a straight blade at the top and two curved blades respectively located on both sides of the handle.

[0010] Preferably, the telescopic rod has a hanging hole in the middle.

[0011] Preferably, the telescopic rod is equipped with a shoulder strap.

[0012] Preferably, the multi-functional knife further includes an angle adjustment component, which includes two symmetrically arranged clamping plates on the top of the handle, first positioning holes respectively on the two clamping plates with their axes aligned on the same straight line, multiple slots on one of the first positioning holes extending circumferentially away from the axis, a second positioning hole in the middle of the double-edged blade, and a fastening bolt and a locking cap passing through the first positioning hole and the second positioning hole in sequence; the inner wall of the second positioning hole is provided with a first tooth; the head of the fastening bolt is provided with a protrusion that matches the slot; the screw of the fastening bolt is provided with a second tooth that matches the first tooth; the second tooth is located on the side near the head of the screw.

[0013] Preferably, the gas pipe also includes a gas pipe winding mechanism connected to the bottom end of the gas pipe; the gas pipe winding mechanism includes a housing, a spool located at the center inside the housing, a spiral spring connected to the spool on one side and to the housing on the other side, a gas cylinder fixing bracket on the housing, and an extension tube wound on the spool; the housing is provided with an inlet for connecting the extension tube to the gas pipe and an outlet for connecting the extension tube to the gas cylinder; one end of the gas pipe is provided with a first connector for connecting to the extension tube, and the other end of the extension tube is provided with a gas cylinder connector for connecting to the gas cylinder.

[0014] Preferably, the inlet is provided with a locking element that is sleeved on the extension tube.

[0015] Preferably, the ignition mechanism includes a second connector detachably connected to the top of the telescopic rod, a bend connected to the second connector and communicating with the gas pipe, a remote control component disposed on the bend, a burner disposed on the top of the bend and adjacent to the output end of the remote control component, and a flame tube disposed outside the burner.

[0016] Preferably, it also includes a storage box for accommodating the gas pipe winding mechanism, ignition mechanism, multi-tool, gas canister and tools.

[0017] The beneficial effects of this utility model are as follows: This application avoids bending of the gas pipe during use by using an anti-bending base, making the honeycomb ignition faster and more stable, and avoiding personnel injury accidents caused by the escape of the bee swarm. At the same time, the structure is simple. When in use, firefighters can directly place the telescopic rod against the ground or a nearby support, realizing single-person operation and greatly saving the physical strength of firefighters. Since the anti-bending base has a simple and lightweight structure, it will not significantly increase the weight of the device, and also avoids physical consumption of firefighters during use.

[0018] This application utilizes a T-shaped multi-functional knife with a straight blade to clean small honeycomb cells and burned honeycomb cells. The curved blades on both sides of the handle of the multi-functional knife can clear surrounding obstructions, making it easier to operate and preventing the burning of honeycomb cells from igniting other combustibles, thus improving operational safety.

[0019] The hanging hole allows for the hanging of a remote control and safety rope, preventing loss and making operation easier. It effectively prevents the device from falling during use and improves safety.

[0020] The telescopic pole is carried on the front of the firefighter's body via a shoulder strap, which prevents the pole from falling off and greatly saves the firefighter's energy. It is easy to carry, improves the safety of the device, and enhances its ease of use. It is more labor-saving and easy to operate, and can be operated by a single person throughout the entire process.

[0021] This application has the advantages of simple structure, wide applicability, and convenient use. It can be operated by a single person, reducing the labor intensity of rescue personnel, saving more time and effort, and is safer. Attached Figure Description

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, 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 according to the specific circumstances. Specific Implementation Example 1

[0032] like Figure 1 and Figure 2As shown, this utility model provides a novel honeycomb removal device, including a multi-stage telescopic rod 100 with a hollow center, a gas pipe 110 disposed inside the telescopic rod 100, an ignition mechanism 200 connected to the gas pipe 110 and detachably disposed at the top of the telescopic rod 100, an anti-bending base 300 disposed at the bottom of the telescopic rod 100 and having a through hole in the middle to facilitate the passage of the gas pipe 110, and a multi-functional knife 400 detachably disposed at the top of the telescopic rod 100; the multi-functional knife 400 is T-shaped; the multi-functional knife 400 includes a handle 410 detachably connected to the telescopic rod 100, and a double-edged blade 420 disposed at the top of the handle 410. The anti-bending base 300 includes a circular tube 310 whose top is connected to the bottom of the telescopic rod 100, and at least one U-shaped hole 320 located at the bottom of the circular tube 310. In this embodiment, there is one U-shaped hole 320. The width and height of the U-shaped hole 320 are both greater than the diameter of the gas pipe 110. Because the extended space of the anti-bending base 300 provides inclined guiding space for the gas pipe 110, bending is avoided, ensuring a stable gas supply. The anti-bending base 300 can be connected to the bottom of the telescopic rod 100 via threads, a snap-fit ​​structure, or direct fixed connection; no specific limitation is made here. The device also includes a gas pipe winding mechanism 500 connected to the bottom end of the gas pipe 110; the gas pipe winding mechanism 500 includes a housing 510, a spool located at the center inside the housing 510, a spiral spring connected to the spool on one side and to the housing 510 on the other side, a gas canister holder 520 on the housing 510, and an extension pipe 530 wound on and connected to the spool; the housing 510 is provided with an inlet 540 for connecting the extension pipe 530 to the gas pipe 110 and an outlet 550 for connecting the extension pipe 530 to the gas canister; one end of the gas pipe 110 is provided with a first connector for connecting to the extension pipe 530, and the other end of the extension pipe 530 is provided with a gas canister connector for connecting to the gas canister. A locking member 560 is provided at the inlet 540 and fitted onto the extension pipe 530. The locking element 560 includes a balloon sleeved on the gas pipe 110 and a friction plate made of rubber at the connection between the balloon and the gas pipe 110. The locking element 560 effectively prevents the extension tube 530 from retracting into the housing 510 after it has been extended to the required length.When the extension tube 530 needs to be retracted into the outer casing 510, it can be manually pulled between the first connector and the inlet 540. The ignition mechanism 200 includes a second connector 210 detachably connected to the top of the telescopic rod 100, a bend 220 connected to the second connector 210 and communicating with the gas pipe 110, a remote control component 230 disposed on the bend 220, a burner 240 disposed on the top of the bend 220 and adjacent to the output end of the remote control component 230, and a flame tube 250 disposed outside the burner 240. Compared with the upward-spraying design in the prior art, the bend 220 makes it easier for firefighters to ignite the honeycomb, especially for honeycombs located in corners. The first connector and the second connector 210 have the same structure, both being gas pipe 110 mating joints, which are prior art and will not be described in detail here. The remote control component 230 includes a remote controller, a battery, a controller electrically connected to the battery, an ignition electronic wire electrically connected to the controller, and an ignition sensing needle electrically connected to the ignition electronic wire. The ignition sensing needle is located inside the flame tube 250. The remote control component 230 is existing technology and will not be described in detail here.

[0033] Example 2

[0034] This embodiment also provides a novel honeycomb removal device, which has a basically the same structure as Embodiment 1, except that:

[0035] like Figure 3 As shown, the double-edged blade 420 includes a straight blade 421 at the top and two curved blades 422 respectively located on both sides of the handle 410. The straight blade 421 can directly remove honeycomb, while the curved blades 422 are more convenient for removing obstacles such as branches and require less effort.

[0036] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the anti-bending base 300 includes a circular tube 310 connected to the bottom of the telescopic rod 100, a support tube 330 connected to the bottom of the circular tube 310 and having an inner diameter larger than that of the circular tube 310, and a U-shaped hole 320 provided on the support tube 330. There are two U-shaped holes 320, which are arranged opposite each other along the outer edge of the anti-bending base 300 to provide guidance in different directions, eliminating the need to rotate the anti-bending base 300 and making operation easier. The diameter of the U-shaped hole 320 is more than 1.5 times the diameter of the gas pipe 110. Due to the increased diameter, the gas pipe 110 is inclined at the U-shaped hole 320. At this time, the anti-bending base 300 can be directly supported on the ground or a protruding part of a building, making it easier for firefighters to operate.

[0037] In summary, compared with Embodiment 1, this embodiment not only achieves the technical effects of Embodiment 1, but also, due to the setting of the curved blade 422, makes it easier to clear obstacles around the honeycomb, avoiding secondary accidents, and the operation is more time-saving and labor-saving. At the same time, due to the precise improvement of the anti-bending base 300, the telescopic rod 100 can be directly supported on the ground without bending, ensuring a stable gas supply to the ignition mechanism 200, greatly reducing the physical exertion of rescue personnel, and allowing a single person to carry out the rescue operation, saving time and labor.

[0038] Example 3

[0039] This embodiment also provides a novel honeycomb removal device, which has a basically the same structure as Embodiment 1, except that:

[0040] The telescopic rod 100 has a hanging hole 120 in the middle. This hanging hole 120 can be directly fixed to the outermost layer of the telescopic rod 100, or it can be fixed to a clamp fitted onto the outermost layer of the telescopic rod 100, thus achieving a detachable connection. No specific limitation is made here. The hanging hole 120 can be used to hang the remote control of the ignition mechanism 200, making one-handed operation easier, or it can be used to hang a safety rope to prevent the telescopic rod 100 from falling. The telescopic rod 100 is also equipped with a shoulder strap for easy carrying. The shoulder strap is detachable. The outer shell 510 of the gas pipe winding mechanism 500 is provided with two hanging holes 570 for connecting with the shoulder strap. In actual use, the shoulder strap is removed from the telescopic rod 100 and connected to the hanging holes 570 of the gas pipe winding mechanism 500. The connection between the shoulder strap and the hanging holes 570 can refer to the connection method between the shoulder strap and the bag body of a crossbody bag, which is existing technology and will not be described in detail here. The gas pipe winding mechanism 500 can then be carried on the rescuer's body, which is convenient for single-person operation.

[0041] Furthermore, the number of the U-shaped holes 320 is three, which are equidistantly arranged along the circumference of the anti-bending base 300.

[0042] Furthermore, the multi-functional knife 400 is detachably connected to the telescopic rod 100 via a third connector 430. The third connector 430 may be a clamp located at the bottom of the knife handle 410, and a nut and bolt for fastening the clamp; furthermore, the third connector 430 also includes a connecting rod 431 connected to the clamp, and at least one rivet connecting the connecting rod 431 to the knife handle 410.

[0043] Furthermore, such as Figure 4 and Figure 5As shown, the multi-functional knife 400 also includes an angle adjustment component 600. The angle adjustment component 600 includes two symmetrically arranged clamping plates 610 on the top of the handle 410, first positioning holes 620 respectively on the two clamping plates 610 with their axes aligned, multiple slots 621 on one of the first positioning holes 620 extending circumferentially away from the axis, a second positioning hole 630 in the middle of the double-edged blade 420, and fastening bolts 640 and locking caps passing through the first positioning holes 620 and the second positioning holes 630 in sequence. The two clamping plates 610 are arranged parallel and opposite to each other. After the fastening bolt 640 passes through the first positioning hole 650 with the slots 621, it passes through the second positioning hole 630, then through the other first positioning hole 650, and is then fixed and locked by the locking cap. The inner wall of the second positioning hole 630 is provided with a first tooth 631; the head of the fastening bolt 640 is provided with a protrusion 641 that matches the bayonet 621, and the screw of the fastening bolt 640 is provided with a second tooth 642 that matches the first tooth 631, the second tooth 642 extending away from the screw shaft; the second tooth 642 is located near the head of the screw; the tail of the fastening bolt 640 is provided with an external thread 643, and the inner wall of the locking cap is provided with a thread that matches the external thread. The internal thread 643 is compatible with the standard thread. During use, after slightly pulling the fastening bolt 640 outwards, rotating it causes the first tooth 631 and the second tooth 642 to mesh, thus rotating the double-edged blade 420. Once the appropriate angle is reached, the fastening bolt 640 is pressed back into the first positioning hole 620, and the protrusion 641 of the fastening bolt 640 engages with the bayonet 621. The locking cap is then used to lock it on the other side, thus fixing the angle of the double-edged blade 420. At least three protrusions 641 are provided, and the number of bayonets 621 is correspondingly increased. When dealing with confined spaces such as honeycomb or surrounding obstacles that make it difficult to operate the multi-tool 400, the angle of the multi-tool 400 can be adjusted for easier operation.
