Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective fence devices, specifically to forest farm protective fence devices. Background Technology
[0002] my country has vast forest areas, encompassing various types such as natural forests, plantations, and economic forests. These forests are not only core carriers of timber resources and biodiversity but also ecological barriers that regulate climate and conserve water resources. Forest farms, as the basic units of forestry resource management, undertake multiple functions including timber production, ecological protection, and forest fire prevention. However, forest farms generally face threats such as illegal logging and poaching, human-caused damage, pest and disease invasion, and fire hazards. Protective fencing, as the "first line of defense" for forest farms, directly determines the effectiveness of resource protection and ecological security.
[0003] Existing protective fencing devices use cement pillars and metal stakes as fixed supports, and horizontally tension steel wire mesh, wooden fences or concrete slabs to form a continuous solid barrier. In some high-risk areas, additional barbed wire or razor wire is installed to increase the difficulty of crossing. Through the "spatial blocking" effect of the solid structure, it directly prevents people and animals from entering the core area of the forest farm, while clearly defining the boundaries of the forest farm and reducing accidental human intrusion.
[0004] Traditional security approaches generally assume that height determines effectiveness, thus often strengthening anti-climbing capabilities by increasing the height of fence posts and increasing the spacing of horizontal steel cables. While this design can hinder unarmed climbers to some extent, the lack of alarm devices and reliance solely on physical fencing means that security personnel can only prevent intruders through patrols, resulting in poor overall security. Utility Model Content
[0005] To overcome the shortcomings of existing technology, the purpose of this utility model is to provide a forest farm protective fence device. When an outsider enters the forest farm by climbing over the fence, he will pull the first fixed rod when he reaches the top. At this time, the first fixed rod drives the slider to slide down in the first groove and stretches the first spring, so that the buckle matches the positioning groove under the positioning plate, thereby fixing the position of the baffle and blocking the signal of the infrared sensor. Then the signal is transmitted to the alarm module, and the alarm module sounds an alarm to remind the guards so as to drive away the outsider in time.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] The forest protection fence device includes an installation block; it also includes a first groove and a protective component; the installation block has a first groove extending through its left and right ends, a slider is slidably installed on the inner wall of the first groove, a baffle is fixed between two sliders, a first fixing rod is fixed to the outside of the slider, a first spring is fixed between the slider and the top of the inner wall of the installation block, an infrared sensor is fixed to the inner wall of the installation block, a buckle is fixed to the outer wall of the slider, a positioning plate is fixed to the inner wall of the installation block, an alarm module is fixed to the upper end of the installation block, and a protective component is installed at the lower end of the installation block.
[0008] In one optional implementation, the buckle is adapted to the positioning groove on the outer wall of the positioning plate, and the infrared sensor is electrically connected to the alarm module.

[0011] In one optional embodiment, two support plates are fixedly connected between the two columns, and multiple connecting plates are fixedly connected between the two support plates. A power supply module is provided on the inner wall of the column, and a circuit board is provided at the lower end of the power supply module. Multiple first contacts are fixedly connected to the left and right ends of the circuit board.
[0012] In one optional embodiment, the protective component includes a limiting frame, a plurality of limiting frames are fixedly connected to the inner wall of the column, a fixing plate is slidably disposed on the inner wall of the limiting frame, and a second spring is fixedly connected between the fixing plate and the inner wall of the column.
[0013] In one optional embodiment, a second contact is fixedly connected to the left end of the fixing plate, an alarm is fixedly connected to the lower end of the fixing plate, a wire hole is opened through the outer wall of the column, and a protective steel wire is fixedly connected to the right end of the fixing plate. The protective steel wire passes through the wire hole and is fixedly connected to the fixing plate on the other side.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. When an outsider enters the forest by climbing over the fence, they will pull the first fixed rod when they reach the top. At this time, the first fixed rod will drive the slider to slide down in the first groove and stretch the first spring, so that the buckle matches the positioning groove under the positioning plate, thereby fixing the position of the baffle and blocking the signal of the infrared sensor. Then the signal is transmitted to the alarm module, and the alarm module will sound an alarm to remind the guards so that the outsider can be driven away in time.
[0016] 2. The buckle is inserted into the positioning groove of the positioning plate to fix the position of the baffle, so that the baffle can continuously block the signal of the infrared sensor and continuously issue an alarm. The exhaust port is connected to the gas storage pipe to ensure the flow of gas. When the gas flows through the alarm whistle, it will emit a sharp alarm sound, thus avoiding the situation where the alarm fails due to the failure of electronic components.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.
[0027] As a vital carrier of forest resources, forest farms not only undertake core functions such as ecological regulation (carbon sequestration and oxygen release, water conservation, and soil and water retention) and biodiversity protection, but also provide raw material support for industries such as timber processing and forest by-product development. They are a crucial cornerstone for ecological security and economic development. my country has 3.46 billion mu (approximately 238 million hectares) of forest land, of which planted forests account for over 30%. However, these forest farms have long faced multiple threats, including illegal logging and poaching, pest and disease invasions, fire hazards, and human-caused damage. According to statistics from the National Forestry and Grassland Administration, annual losses of forest resources due to various forms of damage exceed 10 billion yuan, with ecological restoration costs reaching several billion yuan. Therefore, constructing a reliable forest farm protection system, especially optimizing core protective facilities—protective fencing—has become a key link in ensuring forest resource security and improving forest farm management efficiency.
[0028] The threats facing forest farms today are becoming increasingly diverse and complex, leading to a more comprehensive demand for protective fencing: First, illegal logging and poaching are prominent issues, with criminals profiting from felling valuable trees and hunting wild animals. Traditional fencing is easily cut down and climbed over, making it difficult to provide effective barriers. Second, the risk of pest and disease transmission is escalating. Invasive pests such as pine wilt nematodes and fall webworms can enter forest farms through human-borne or vehicle-transported means, and physical fencing alone cannot prevent their spread. Third, frequent human activities, such as grazing, harvesting, and burning straw by nearby residents, can easily trigger forest fires. Data shows that human-caused forest fires account for over 70% of all forest fires in my country each year, and traditional fencing lacks early warning capabilities, often only being detected after a fire has occurred. Fourth, the demands for ecological protection and management are upgrading. Modern forest farms need precise control over the entry and exit of personnel and vehicles, while also considering the eco-friendliness of wildlife migration routes. The "one-size-fits-all" approach of traditional fencing no longer meets the requirements of ecological protection.
[0029] Existing forest protection fences are mainly divided into three categories: physical protection, biological protection, and simple warning. However, all of them have obvious functional limitations and cannot meet the comprehensive protection needs of modern forest farms.
[0030] Physical protective fencing is currently the most widely used type, including wire mesh fencing, concrete post fencing, and steel pipe fencing, all relying on physical barriers for protection. Wire mesh fencing is relatively inexpensive (costing 20-50 yuan per meter), but its strength is insufficient; ordinary wire mesh is easily cut with pliers, and even high-strength galvanized steel wire (4-6mm diameter) is insufficient to withstand vehicle impacts. Concrete post fencing is strong and durable (10-15 years lifespan), but construction is difficult, requiring on-site pouring or heavy equipment hoisting. Construction efficiency is extremely low in complex terrains such as mountains and hills (less than 50 meters per day), and its weight (50-100kg per post) leads to high transportation costs. While steel pipe fencing combines strength and flexibility, its cost exceeds 100 yuan per meter, making large-scale application uneconomical. Furthermore, the surface of steel pipes is prone to rust, requiring rust removal and maintenance every 3-5 years in rainy and humid southern forest areas, increasing operating costs. In addition, physical fences often have the problem of "over-blocking". For example, a 1.8-meter-high wire fence can block the migration routes of small animals such as rabbits and deer, and damage the integrity of the food chain.
[0031] Biological fencing, which forms a natural barrier by planting thorny shrubs (such as jujube and Sichuan pepper) or trees, has the advantages of being eco-friendly and low-cost, making it suitable for forest farms in ecologically sensitive areas. However, the protective effect of biological fencing depends on the plant growth cycle, typically requiring 3-5 years to form an effective barrier, resulting in weak short-term protective capabilities. Furthermore, it is significantly affected by climate and soil conditions; in arid and cold regions, the plant survival rate is less than 50%, making it difficult to form a continuous protective belt. Additionally, biological fencing cannot prevent people from climbing over it or small animals from burrowing through, and its effectiveness in preventing illegal logging and poaching is limited.
[0032] Simple warning fences are mostly constructed using plastic mesh, warning tape, and posts, serving only as boundary markers and warnings. They are extremely inexpensive (costing 5-10 yuan per meter) but offer almost no real barrier capability, making them suitable only for temporary fencing or low-risk areas. In areas with high rates of illegal logging and poaching, these fences are often directly destroyed, rendering their warning function ineffective.
[0033] Besides functional limitations, existing fences suffer from three major pain points: First, they lack proactive early warning capabilities. Traditional fences can only passively block access, and when fence damage or intrusion occurs, they rely on manual patrols for detection. However, forest areas typically cover thousands or even tens of thousands of acres, making manual patrols incomplete and slow to respond. For example, illegal loggers can complete logging and escape within 2-3 hours after damaging the fence, and patrol personnel often only discover it the next day, missing the opportunity to apprehend them. Second, they have low levels of intelligence and cannot be linked with the forest management system. Managers find it difficult to monitor the overall status of the fence in real time, such as whether a section of the fence is damaged or where the intrusion is located, leading to low management efficiency. Third, they have poor adaptability and insufficient ability to adapt to complex terrains. In mountainous or swampy areas with slopes greater than 30°, it is difficult to fix the posts of physical fences, which are prone to tilting and collapsing due to foundation settlement. Biological fences, on the other hand, cannot survive due to the limitations of plant growth conditions.
[0034] With the advancement of smart forestry construction, the demand for protective fencing in forest farm management has evolved from "simple barrier" to an integrated system encompassing "barrier-early warning-control-ecological compatibility." For example, in nature reserve forest farms, fencing must simultaneously "block illegal intrusion" and "protect wildlife migration"; in commercial forest farms, fencing must provide early warnings to promptly detect illegal logging and reduce economic losses; and in border forest farms, it must also address the prevention and control of cross-border poaching and pest intrusion. Furthermore, under the "dual carbon" goal, forest farm protective fencing needs to develop towards low-carbon practices, reducing the use of high-carbon emission materials such as cement and steel to improve ecological benefits.
[0035] Please refer to Figures 1-5This utility model provides an embodiment of a forest farm protective fence device, including an installation block 1; it also includes a first groove 101 and protective components; the first groove 101 is provided through the left and right ends of the installation block 1, a slider 102 is slidably arranged on the inner wall of the first groove 101, a baffle 103 is fixedly connected between two sliders 102, a first fixing rod 104 is fixedly connected to the outer side of the slider 102, a first spring 105 is fixedly connected between the slider 102 and the top of the inner wall of the installation block 1, an infrared sensor 106 is fixedly connected to the inner wall of the installation block 1, a buckle 107 is fixedly connected to the outer wall of the slider 102, a positioning plate 108 is fixedly connected to the inner wall of the installation block 1, an alarm module 109 is fixedly connected to the upper end of the installation block 1, and a protective component is provided at the lower end of the installation block 1. When an outsider enters the forest by climbing over the fence, they will pull the first fixing rod 104 when they reach the top. At this time, the first fixing rod 104 will drive the slider 102 to slide downward in the first groove 101 and stretch the first spring 105, so that the buckle 107 is matched with the positioning groove under the positioning plate 108, thereby fixing the position of the baffle 103 and blocking the signal of the infrared sensor 106. Then the signal is transmitted to the alarm module 109, and the alarm module 109 will sound an alarm to remind the guards. This solves the problem that the current protective fence device lacks an alarm device and only relies on the physical barrier of the fence. The guards can only rely on patrols to prevent outsiders from entering, resulting in poor protection effect.
[0036] Please refer to Figures 1-4 In a preferred embodiment of this utility model, the buckle 107 is adapted to the positioning groove on the outer wall of the positioning plate 108, the infrared sensor 106 is electrically connected to the alarm module 109, the lower end of the slider 102 is fixedly connected to the pressing block 2, the bottom end of the inner wall of the mounting block 1 is fixedly connected to the air storage pipe 3, the pressing block 2 is slidably disposed on the inner wall of the air storage pipe 3, the outer wall of the mounting block 1 is provided with an exhaust port 4, the exhaust port 4 is interconnected with the air storage pipe 3, the inner wall of the exhaust port 4 is provided with an alarm whistle 5, the lower end of the mounting block 1 is provided with a column 6, the mounting block 1 is fixedly connected to the column 6 by a fastener, two support plates 7 are fixedly connected between the two columns 6, and a [missing information - likely a component or material] is fixedly connected between the two support plates 7. Multiple connecting plates 8 and a power supply module 9 are installed on the inner wall of the column 6. A circuit board 10 is installed at the lower end of the power supply module 9. Multiple first contacts 11 are fixed to the left and right ends of the circuit board 10. The power supply module 9 supplies power to the electronic components through an internal battery. The buckle 107 is inserted into the positioning groove of the positioning plate 108 to fix the position of the baffle 103, so that the baffle 103 can continuously block the signal of the infrared sensor 106 to continuously issue an alarm. The exhaust port 4 is connected to the gas storage pipe 3 to ensure the flow of gas. When the gas flows through the alarm whistle 5, it will emit a sharp alarm sound, thereby avoiding the situation where the electronic components fail to alarm due to problems.
[0037] Please refer to Figure 4 and Figure 5In a preferred embodiment of this utility model, the protective component includes a limiting frame 201. Multiple limiting frames 201 are fixedly connected to the inner wall of the column 6. A fixing plate 202 is slidably disposed on the inner wall of the limiting frame 201. A second spring 203 is fixedly connected between the fixing plate 202 and the inner wall of the column 6. A second contact point 204 is fixedly connected to the left end of the fixing plate 202. An alarm 205 is fixedly connected to the lower end of the fixing plate 202. A wire hole 206 is provided through the outer wall of the column 6. A protective steel wire 207 is fixedly connected to the right end of the fixing plate 202. The protective steel wire 207 passes through the wire hole 206 and connects to the fixing plate 202 on the other side. With a fixed connection, the protective steel wire 207 is taut under normal conditions. The two ends of the protective steel wire 207 drive the fixing plate 202 to compress the second spring 203. If an outsider attempts to damage the fence, the protective steel wire 207 breaks. Under the action of the second spring 203, the fixing plate 202 slides within the limit frame 201, causing the second contact 204 at the left end of the fixing plate 202 to contact the first contact 11 on the circuit board 10, connecting the circuit and causing the alarm 205 at the lower end of the fixing plate 202 to sound an alarm. This allows for protection from multiple angles, improving the protective effect of the fence.
[0038] In use, when an outsider enters the forest by climbing over the fence, reaching the top will pull the first fixing rod 104. At this time, the first fixing rod 104 drives the slider 102 to slide downward in the first groove 101 and stretch the first spring 105, so that the buckle 107 matches the positioning groove below the positioning plate 108, thereby fixing the position of the baffle 103 and blocking the signal of the infrared sensor 106. Then the signal is transmitted to the alarm module 109, which sounds an alarm to remind the caretaker. At the same time, the slider 102 drives the squeezing block 2 to slide downward in the gas storage pipe 3, squeezing the gas in the gas storage pipe 3. The gas is discharged from the exhaust port 4 and passes through the alarm whistle 5, causing the alarm whistle 5 to sound, which, together with the alarm module 109, enhances the warning effect.
[0039] Under normal conditions, the protective steel wire 207 is taut. Both ends of the protective steel wire 207 drive the fixing plate 202 to compress the second spring 203. If an outsider attempts to damage the fence, the protective steel wire 207 breaks. Under the action of the second spring 203, the fixing plate 202 slides within the limit frame 201, causing the second contact 204 at the left end of the fixing plate 202 to contact the first contact 11 on the circuit board 10, connecting the circuit and causing the alarm 205 at the lower end of the fixing plate 202 to sound an alarm. This allows for protection from multiple angles, improving the protective effect of the fence.
[0040] Through the above steps, when an outsider enters the forest by climbing over the fence, they will pull the first fixed rod 104 when they reach the top. At this time, the first fixed rod 104 will drive the slider 102 to slide downward in the first groove 101 and stretch the first spring 105, so that the buckle 107 is matched with the positioning groove below the positioning plate 108, thereby fixing the position of the baffle 103 and blocking the signal of the infrared sensor 106. Then the signal is transmitted to the alarm module 109, and the alarm module 109 will sound an alarm to remind the guards. This solves the problem that the current protective fence device lacks an alarm device and only relies on the physical barrier of the fence. The guards can only rely on patrols to prevent outsiders from entering, resulting in poor protection effect.

[0042] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
