Description

Technical Field

[0001] This utility model patent relates to the field of forestry equipment technology, specifically to a forestry operation warning device. Background Technology

[0002] This device belongs to the field of forestry operation safety protection technology. It is a forestry operation warning device that is applied to forestry planting, pruning, logging and other operation scenarios. It is used to protect and warn seedlings and operation areas to prevent personnel and equipment from accidentally touching seedlings and causing damage or safety accidents.

[0003] Currently, the existing warning devices used in forestry operations mainly include independent warning signs, warning tapes, and fixed warning lights. Their operating principle is to use visual markers to alert workers to specific areas. The purpose (technical effect) is to delineate the work area and warn of dangerous zones, thereby reducing the occurrence of misoperations.

[0004] However, existing technologies have several shortcomings: First, the warnings lack specificity and are difficult to set precisely around the seedlings, easily creating warning blank areas around them; second, the coverage area is fixed and cannot be flexibly adjusted according to the scale of the operation, resulting in poor adaptability; third, the fixing is not stable enough, and it is easy to shift or even tip over under the action of external forces such as wind or when it is hit, affecting the warning effect; fourth, the warning method is relatively passive, mostly static signs, which cannot respond to people or animals that approach in a timely manner, resulting in a warning lag; fifth, when multiple warning devices are used in conjunction, power supply is very cumbersome, especially in the field environment, and powering each device separately will increase costs and make operation inconvenient.

[0005] Based on the above, the technical objective (design requirements) of this device is to provide a forestry operation warning device that can accurately protect seedlings, flexibly expand the warning range, be firmly fixed, provide dynamic real-time warnings, and has convenient power supply. The device should possess the following technical advantages: it can be specifically fixed around seedlings; the warning range can be flexibly adjusted; it can adapt to complex terrain and be firmly fixed; it can dynamically trigger warnings; and multiple devices can be powered collaboratively. Summary of the Invention

[0006] To address some or all of the aforementioned technical problems, this application provides a forestry operation warning device with the technical advantages of precise seedling protection, flexible and adjustable warning range, stable fixation, dynamic real-time warning, and coordinated power supply for multiple devices.

[0007] A forestry operation warning device includes at least one protective support; the protective support comprises: a crossbar; a fixing clamp connected to one end of the crossbar for fixing seedlings; two extendable side arms connected to the other two sides of the crossbar via universal joints, each extendable side arm equipped with a warning light; an infrared detection device mounted on the crossbar and facing the fixing clamp for detection operations; a storage battery disposed inside the crossbar and electrically connected to the infrared detection device, the warning light, and other electrical components, the storage battery having lead-out lines; a telescopic sleeve built into the connecting end of each extendable side arm, the telescopic sleeve being sequentially connected to a spring and the inner bottom surface of the connecting end of the extendable side arm, the free ends of the two telescopic sleeves respectively equipped with hook rings and hook components; a fixing component cooperating with the crossbar is provided on the side of the connecting end of the extendable side arm; when the infrared detection device detects an infrared signal, it can trigger the warning light to flash.

[0008] By adopting the above technical solution, the protective bracket uses the crossbar as the main frame. One end is stably connected to the seedling through a fixing clamp, and the other end is connected to the unfolded side arms through universal joints on both sides. The telescopic sleeves built into the connecting end of the unfolded side arms are connected to the spring and the inner bottom surface of the unfolded side arms in sequence. The hook rings and hooks at the free ends of the two telescopic sleeves can realize the connection of multiple brackets. The fixing components on the side of the connecting end are constrained and fixed with the crossbar. The crossbar also integrates an infrared detection device and a built-in battery. The battery supplies power to the infrared detection device, warning lights and other electrical components through lead-out lines, and multiple protective brackets can share the power supply.

[0009] After the device is fixed to the seedling with the fixing clip, the angle of the extended side arm can be adjusted with the help of the universal joint. The telescopic sleeve adapts to different spacing requirements under the action of the spring. The fixing component ensures that the extended side arm is fixed relative to the crossbar. A single device forms a basic warning unit around the seedling, and multiple devices are connected to the hook ring and hook to form a protective warning area. When the infrared detection device detects an infrared signal in the direction of the fixing clip, the warning light is immediately triggered to flash.

[0010] Optionally, multiple protective brackets are connected by the hook ring and the hook piece to form a protective warning area, and different protective brackets can share the power supply of the storage battery through the lead-out line.

[0011] By adopting the above technical solution, the structural connection of multiple protective supports working together becomes closer: each protective support maintains the characteristics of the crossbar main frame of an independent unit, and adjacent protective supports are mechanically connected by hook rings and hooks at the free ends of the extended side arm telescopic sleeves to form a continuous protective warning area outline; at the same time, the lead-out lines of different protective supports are interconnected, so that the battery power supply network covers the entire area and realizes the sharing of power resources.

[0012] Optionally, multiple crossbars are provided, and the multiple crossbars and the fixing clamp form a triangular structure.

[0013] By adopting the above technical solution, a stable structural connection is formed between the crossbars and the fixing clamp: one end of each of the crossbars is connected to the fixing clamp, and the other end is connected to the corresponding unfolded side arm, forming a triangular structure. This triangular structure utilizes the principle of geometric stability to create a mutually supporting force system between the connection point of the fixing clamp and the seedling, and between the connection point of each crossbar and the unfolded side arm.

[0014] Optionally, the fixing clamp includes a clamping part and a locking member that cooperate with each other. The clamping part is used to fit against the surface of the seedling, and the locking member adopts a bolt or belt buckle structure to tighten and fix the clamping part.

[0015] By adopting the above technical solution, the clamping part and the locking part cooperate with each other. The clamping part fits against the surface of the seedling to form a contact base, and the locking part applies a tightening force to the clamping part through a bolt or belt buckle structure, so that the fixing clamp is tightly connected to the seedling.

[0016] Optionally, the fixing component includes a buckle protrusion disposed on the side of the connecting end of the unfolded side arm and a buckle groove disposed at the corresponding position of the crossbar, wherein the buckle protrusion and the buckle groove cooperate to achieve buckling and fixing; or the fixing component includes a magnet disposed on the side of the connecting end of the unfolded side arm and a magnetic absorbing piece disposed at the corresponding position of the crossbar, wherein the magnet and the magnetic absorbing piece cooperate to achieve magnetic fixing.

[0017] By adopting the above technical solutions, the fixing components form a reliable constraint structure between the unfolded side arm and the crossbar: in the snap-fit ​​fixing method, the snap-fit ​​protrusion on the side of the connecting end of the unfolded side arm cooperates with the snap-fit ​​groove at the corresponding position of the crossbar; in the magnetic fixing method, the magnet on the side of the connecting end of the unfolded side arm attracts the magnetic piece at the corresponding position of the crossbar. Both methods can achieve relative fixation between the unfolded side arm and the crossbar.

[0018] Once the extended side arm is adjusted to the required angle, the buckle protrusion can engage with the buckle groove to form a positioning constraint through mechanical engagement; or the magnet and the magnetic accumulator will adhere to each other under the action of magnetic force, and the position will be fixed by magnetic force, thereby limiting the free rotation of the extended side arm under the universal joint connection and ensuring that it maintains the preset warning angle during operation.

[0019] Optionally, the infrared detection device is electrically connected to the warning light, and when the infrared detection device detects an infrared signal, it controls the warning light to flash via an electrical signal.

[0020] By adopting the above technical solution, the infrared detection device continuously emits and receives infrared signals in the direction of the fixed clamp. When infrared radiation sources such as people and animals are detected, the internal circuit of the detection device generates an electrical signal change. This electrical signal is transmitted to the warning light through the connecting wire, triggering the warning light to enter the strobe working mode and issue a warning by flashing a strong light.

[0021] Optionally, the crossbar has a receiving cavity, and the battery is fixed inside the receiving cavity.

[0022] Optionally, the end of the lead-out line is provided with a suitable plug and socket, and the lead-out lines of different protective brackets are electrically connected through the cooperation of the plug and socket.

[0023] By adopting the above technical solution, the lead-out line forms an electrical connection structure that can be quickly connected: the ends of the lead-out line are respectively equipped with suitable plugs and sockets, and the interface specifications of the plugs and sockets match each other, forming a physical connection medium for power transmission between different protective supports.

[0024] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects of forestry operation warning devices:

[0025] The protective bracket with a fixing clip enables precise connection to the seedlings; multiple protective brackets are used, and each bracket is connected to the other via hook rings and hooks to expand the warning area; universal joints, telescopic sleeves, and spring structures enhance the device's adaptability to complex terrain, while buckles, magnetic closures, and other fixing components strengthen the device's stability; an infrared detection device is installed and linked with a flashing warning light for dynamic warning; and a battery lead-out circuit is designed to allow multiple devices to share a power supply.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model patent clearer, the technical solutions of the embodiments of this utility model patent will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model patent, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model patent are within the scope of protection of this utility model patent.

[0031] This application discloses a forestry operation warning device.

[0032] Referring to the accompanying drawings, a forestry operation warning device includes a protective support frame.

[0033] The protective support is mainly composed of a horizontal bar 1 (a 60cm long stainless steel square tube with a cross-sectional size of 3cm×3cm). A fixing clip 2 is welded to one end of the horizontal bar 1. The fixing clip 2 includes two arc-shaped clamping parts (with 3mm thick rubber pads pasted on the inside, and the diameter is suitable for 515cm seedlings) and a locking part (M6 bolts are used to pass through the ear plates on both sides of the clamping parts, and the bolt ends are equipped with wing nuts for easy manual adjustment).

[0034] The other end of the crossbar 1 is connected to two unfolded side arms 3 (aluminum alloy round tubes with a length of 50cm and a diameter of 2cm) by stainless steel universal joints (which can rotate 360° and have damping positioning). The top of the unfolded side arms 3 is fixed with a warning light 4 (12V LED strobe light, power 5W, waterproof rating IP66) by screws.

[0035] The infrared detection device 5 (model HCSR501, detection angle 110°, detection distance 0.5m) is fixed in the middle of the crossbar 1 by a U-shaped buckle. The detection head faces the direction of the fixing clip 2 and is at a 30° downward angle to the axis of the crossbar 1 to focus on the area around the seedling.

[0036] The crossbar 1 has a pre-reserved cavity (20cm long, 2cm wide, and 2cm high) for housing a 12V / 5Ah lithium battery (battery 6). The infrared detection device 5 and the warning light 4 are connected by wires, which are laid along the inner wall of the crossbar 1 and fixed by insulating clips.

[0037] A 1.8cm diameter through hole is provided at the connecting end of the extended side arm 3 (10cm from the end), and a telescopic sleeve 7 (extendable within a length of 1020cm, made of chrome-plated steel pipe) is built in. A spring 8 (compression spring with a diameter of 1cm and a free length of 5cm) is welded to the bottom of the telescopic sleeve 7, and the other end of the spring 8 is welded to the inner bottom surface of the connecting end of the extended side arm 3. Hook rings 9 (stainless steel rings with a diameter of 2cm) and hook parts 10 (stainless steel hooks with spring 8 buckles and an opening width of 1.5cm) are respectively welded to the free ends of the two telescopic sleeves 7.

[0038] The side of the extended side arm 3 is welded with a buckle protrusion (8mm diameter nylon post), and the corresponding position of the crossbar 1 is opened with a buckle groove (9mm diameter round hole). The two work together to achieve buckle fixation; or it can be replaced by: attaching a 1cm diameter neodymium iron boron magnet to the end of the extended side arm 3, and welding a 0.3cm thick iron plate to the corresponding position of the crossbar 1, and fixing it by magnetic attraction.

[0039] Extended structure implementation

[0040] When it is necessary to construct a protective warning area, take three of the above-mentioned protective brackets, fasten the hook 10 of the first bracket into the hook ring 9 of the second bracket, and fasten the hook 10 of the second bracket into the hook ring 9 of the third bracket to form a linearly arranged warning area (the total length can be adjusted by the telescopic sleeve 7, with a range of 13m).

[0041] Meanwhile, a DC plug is installed at the end of the lead wire of the first bracket (a 1m long RVV2×0.5mm² wire extending from the positive terminal of battery 6), and a DC socket is installed at the end of the lead wire of the second bracket (a wire extending from the negative terminal of battery 6). The plug is inserted into the socket to achieve electrical connection. Similarly, the second and third brackets are connected so that the three brackets can share the power supply of battery 6 of the first bracket.

[0042] Work process implementation 1.

[0044] Single bracket use: Place the clamping part of the fixing clip 2 against the trunk of the seedling, rotate the wing nut to tighten the locking part until the device is firmly fixed; pull the unfolding side arm 3 and adjust it to a 90° angle with the crossbar 1 through the universal joint so that the buckle protrusion engages with the buckle groove (or the magnet attracts the iron plate); turn on the power, the infrared detection device 5 starts, and when it detects the infrared signal of personnel within a 3m range, it immediately outputs an electrical signal to the warning light 4, triggering it to flash at a frequency of 10Hz. 2.

[0046] Multiple supports in use: Connect three supports according to the above extended structure to form a triangular protection area around the seedling group; after the main power is turned on, when the infrared detection device 5 of any support detects an infrared signal, the warning lights 4 of all supports will flash synchronously to achieve regional linkage warning.

[0047] Key component coordination implementation

[0048] Electrical connection between infrared detection device 5 and warning light 4: A relay module is used to achieve linkage. When infrared detection device 5 outputs a high-level signal, the relay is activated to turn on the circuit of warning light 4 and trigger the strobe.

[0049] Battery 6 is secured by wrapping it with two insulating rubber pads and then securing it in the housing cavity with stainless steel cable ties to prevent vibration and displacement.

[0050] Telescopic sleeve 7 works in conjunction with spring 8: When the distance between adjacent supports changes, telescopic sleeve 7 compresses or stretches spring 8, automatically adjusting its length to maintain a reliable connection between hook ring 9 and hook piece 10.

[0051] In some embodiments, a rotatable connecting component is added to the free end of the telescopic sleeve 7 at the connecting end of the extended side arm 3: a connecting shaft (made of 45# steel) with a diameter of 1cm is welded to the free end of the telescopic sleeve 7, and a limiting disc with a diameter of 1.5cm is provided at the end of the connecting shaft; a bearing sleeve (with an inner diameter of 1cm and a thickness of 0.5cm) is welded to the inner side of the hook ring 9 (stainless steel ring), and the bearing sleeve is fitted onto the connecting shaft, forming an axial constraint with the limiting disc, so that the hook ring 9 can rotate 60° around the connecting shaft; a bearing sleeve of the same specification is welded to the root of the hook part 10 (stainless steel hook with spring 8 buckle), and is fitted onto the connecting shaft of another telescopic sleeve 7 in the same way, so that the hook part 10 can rotate 60° around the connecting shaft. This structure allows the hook ring 9 and the hook part 10 to rotate adaptively according to the angular deviation of adjacent protective brackets when they are connected, avoiding structural deformation caused by rigid pulling. Especially when multiple brackets form a zigzag warning area, the angular error can be compensated by rotation to ensure the stability of the connection.

[0052] When multiple protective supports are connected to hooks 10 via hook rings 9, the rotatable connection structure allows adjacent supports to form an angle in the horizontal direction. For example, in an area where seedlings are distributed in a zigzag pattern, when the supports are connected sequentially, the rotation of hook rings 9 and hooks 10 allows the middle support to deflect 20° relative to the two side supports. At the same time, the telescopic sleeve 7 maintains its telescopic fit under the action of spring 8, ultimately forming a zigzag protective area that fits the distribution of seedlings. This solves the problem that traditional fixed connections are difficult to adapt to complex seedling arrangements due to angle limitations.
