Description

Technical Field

[0001] This utility model relates to the field of ecological protection engineering technology, specifically to an assembled small mammal biological passage. Background Technology

[0002] With the continuous development of society and the rapid expansion of transportation infrastructure, linear projects such as roads and railways are constantly extending into natural areas, resulting in the severe fragmentation of wildlife habitats. This fragmentation not only directly reduces the available living space for animals but also disrupts gene exchange channels between species, exacerbating the risks of population isolation and inbreeding. For small mammals, whose activity range is limited and whose migration ability is weak, the road barrier effect is even more pronounced. Small mammals often encounter traffic accidents while crossing roads, leading to a sharp decline in local populations. In addition, human disturbances such as streetlights and noise on both sides of roads further alter animal behavior patterns, causing them to avoid their original habitats. In recent years, in order to improve the ecological quality of land remediation areas, maintain and enhance regional biodiversity, and provide guidance for the construction of land remediation and other national spatial ecological restoration projects, biochannels, as a key technology for alleviating habitat fragmentation, have become an important means of maintaining the integrity of ecosystems by constructing safe animal migration routes.

[0003] However, the existing biological passages have a relatively simple structure, usually consisting of simple culverts laid under the road for organisms to cross. Since the inlet and outlet of the culvert are usually exposed, larger animals can easily crawl in and get stuck, causing damage to the inlet and outlet. At the same time, foreign objects such as stones can easily get stuck at the inlet and outlet of the culvert, preventing small mammals from crossing. This reduces the effectiveness of the passage and causes considerable inconvenience for small mammals migrating across the road. Utility Model Content

[0004] The purpose of this invention is to provide an assembled biological passage for small mammals, which solves the problem that the inlet and outlet of the existing culvert are usually exposed, allowing larger animals to crawl in and cause damage. At the same time, it is easy for foreign objects such as stones to get stuck at the inlet and outlet of the culvert, causing more inconvenience to small mammals migrating across the road.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembled small mammalian biological passage, comprising:

[0006] The underground tunnel mechanism and the transition tunnel mechanism assembled on both sides of the underground tunnel mechanism, and the inlet and outlet mechanism assembled on one side of the transition tunnel mechanism;

[0007] The underground tunnel mechanism includes an underground pipe;

[0008] The transition channel mechanism includes telescopic pipes slidably installed at both ends of the buried pipe, a transition inclined pipe connected to one side of the telescopic pipe, an infrared camera fixedly installed on the inner wall of the transition inclined pipe, and a mounting base fixedly installed on one side of the transition inclined pipe.

[0009] The import / export mechanism includes a connecting pipe inserted into the mounting base, one side of which is connected to an access channel, and a guardrail is fixedly installed on one side of the access channel.

[0010] Furthermore, reinforcing ribs are fixedly installed around the periphery of the buried pipe, and the reinforcing ribs are arranged at equal intervals.

[0011] Furthermore, a sliding block is fixedly installed on the surface of the telescopic pipe, and a sliding opening is provided on the inner wall of the buried pipe for the sliding block to slide.

[0012] Furthermore, a limiting block is fixedly installed on one side of the slide block, and the limiting block corresponds to the slide opening.

[0013] Furthermore, anti-slip strips are fixedly installed inside the transition inclined tube, and the anti-slip strips are arranged at equal intervals.

[0014] Furthermore, a retaining ring is fixedly installed on the periphery of the connecting pipe, and a slot for inserting the retaining ring is provided inside the mounting base.

[0015] Furthermore, the front and rear ends of the access channel are fixedly installed with mounting bases, and the surface of the mounting bases is provided with mounting holes.

[0016] Compared with existing technologies, the assembled small mammal biological passage provided by this utility model, by setting up an inlet and outlet mechanism, can intercept the surface of the passage through a protective barrier, allowing small mammals to enter while blocking larger animals. This effectively prevents larger animals from getting stuck inside and unable to exit. At the same time, the inclined shape of the protective barrier allows fallen stones and foreign objects to slide down along the angle of the barrier, preventing stones and other foreign objects from the external environment from entering the inlet and outlet mechanism and causing blockages. The inlet and outlet mechanism is detachable, so when it is damaged, it can be easily replaced separately without replacing the entire passage, which brings more convenience to maintenance work.

[0017] Through the cooperation between the underground tunnel mechanism and the transition tunnel mechanism, the telescopic pipe can be moved along both ends of the underground tunnel. It can be adjusted to a suitable length according to the width of the road. At the same time, it can be adjusted according to the width of the road expansion without replacing the whole structure. This effectively improves the applicability and avoids the trouble of having to customize a specified length according to the road width. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] Example 1:

[0029] This invention provides an assembled small mammalian biological passage, comprising:

[0030] The underground tunnel mechanism 1 and the transition tunnel mechanism 2 assembled on both sides of the underground tunnel mechanism 1, and the entrance and exit mechanism 3 assembled on one side of the transition tunnel mechanism 2;

[0031] The underground tunnel mechanism 1 includes an underground pipe 11;

[0032] The transition channel mechanism 2 includes telescopic pipes 21 that are slidably installed at both ends of the buried pipe 11. One side of the telescopic pipe 21 is connected to a transition inclined pipe 23. An infrared camera 25 is fixedly installed on the inner wall of the transition inclined pipe 23. A mounting base 26 is fixedly installed on one side of the transition inclined pipe 23.

[0033] The import / export mechanism 3 includes a connecting pipe 31 inserted into the mounting base 26. One side of the connecting pipe 31 is connected to an access channel 33, and a guardrail 34 is fixedly installed on one side of the access channel 33.

[0034] As can be seen from the above, by burying the underground pipe 11 into the soil under the road during use, the telescopic pipe 21 can extend and retract along both ends of the underground pipe 11, which can extend the length of the channel. It can be easily adjusted to a suitable length according to the width of the road. At the same time, it can be adjusted according to the width of the road expansion without replacing the whole structure, which effectively improves the scope of application and avoids the trouble of having to customize a specified length according to the road width.

[0035] By utilizing the upward-sloping shape of the transition inclined pipe 23, it can extend upward to the ground surface. By inserting one end of the connecting pipe 31 into the mounting base 26, it is easy to assemble and connect the inlet / outlet mechanism 3 and the transition inclined pipe 23. When the inlet / outlet mechanism 3 is damaged, it can be easily separated from the mounting base 26 by pulling the connecting pipe 31 upward. This allows for easy replacement of the inlet / outlet mechanism 3 without the need to replace the underground channel mechanism 1 and the transition channel mechanism 2, which brings more convenience to the maintenance work and also reduces the maintenance cost.

[0036] The protective fence 34 can intercept and protect the surface of the access passage 33, allowing small mammals to enter while isolating larger animals. This effectively prevents larger animals from getting stuck inside and unable to exit. The inclined design of the fence 34 allows fallen stones and foreign objects to slide down, preventing blockages caused by external debris. Small mammals entering the access passage 33 can then slide down the connecting pipe 31 into the transition inclined pipe 23. The infrared camera 25 can easily capture images of these mammals, allowing personnel to monitor their movement. The animals then descend the slope of the transition inclined pipe 23 into the buried pipe 11, from which they can exit through the other end of the access passage 33. This facilitates the migration of small mammals and contributes significantly to the maintenance of the ecosystem.

[0037] From the appendix Figure 2 It can be seen that the periphery of the buried pipe 11 is fixedly installed with reinforcing ribs 12, which are arranged at equal intervals.

[0038] As can be seen from the above, the structural strength of the buried pipe 11 can be improved by the reinforcing rib 12, which can improve the load-bearing capacity when the buried pipe 11 is buried underground and prevent the buried pipe 11 from being squeezed and deformed. At the same time, the reinforcing rib 12 can increase the friction between the buried pipe 11 and the soil, which can prevent the buried pipe 11 from being displaced when ground vehicles pass by and cause vibration.

[0039] For details, please refer to the appendix. Figure 2 and attached Figure 4 As shown, a slide block 22 is fixedly installed on the surface of the telescopic pipe 21, and a sliding opening 13 is provided on the inner wall of the buried pipe 11 for the slide block 22 to slide.

[0040] As can be seen from the above, when the telescopic tube 21 is extended or retracted, the slide block 22 can slide along the sliding opening 13. By using the limiting effect of the sliding opening 13 on the slide block 22, it is not easy for the telescopic tube 21 and the buried pipe 11 to rotate, thus preventing the transition inclined tube 23 from tilting.

[0041] For details, please refer to the appendix. Figure 4 As shown, a limiting block 28 is fixedly installed on one side of the slide block 22, and the limiting block 28 corresponds to the slide opening 13.

[0042] As can be seen from the above, when the telescopic tube 21 is stretched to its maximum stroke, the limiting block 28 can be engaged on one side of the sliding opening 13. Through the blocking effect of the limiting block 28, the separation between the telescopic tube 21 and the buried pipe 11 can be avoided.

[0043] Working principle: By burying the underground pipe 11 under the road, the telescopic pipe 21 can extend and retract along both ends of the underground pipe 11. The telescopic pipe 21 can be adjusted to a suitable length according to the width of the road. The transition inclined pipe 23 can extend out of the ground by tilting upwards. By inserting one end of the connecting pipe 31 into the mounting base 26, it can be easily connected. The access passage 33 provides an entrance and exit position for small mammals. The guardrail 34 can intercept larger animals, allowing small mammals to pass through the guardrail 34 into the access passage 33. The small mammals can then enter the transition inclined pipe 23 and continue to walk down the transition inclined pipe 23 to pass through the underground pipe 11. The small mammals can then easily exit through the access passage 33 at the other end, completing the crossing quickly.

[0044] Example 2:

[0045] Reference Appendix Figure 3 As shown, anti-slip strips 24 are fixedly installed inside the transition inclined tube 23, and the anti-slip strips 24 are arranged at equal intervals.

[0046] As can be seen from the above, the anti-slip strips 24 arranged at equal intervals can improve the anti-slip effect when small mammals pass by, so that small mammals can move steadily down the transition inclined tube 23 and are less likely to slip and roll down.

[0047] Reference Appendix Figure 5 As shown, a retaining ring 32 is fixedly installed on the periphery of the connecting pipe 31, and a slot 27 for inserting the retaining ring 32 is provided inside the mounting base 26.

[0048] As can be seen from the above, by inserting the retaining ring 32 into the slot 27 from top to bottom, the retaining ring 32 can be conveniently positioned by the slot 27, and the connecting tube 31 and the transition inclined tube 23 can be assembled and connected. At the same time, by pulling the retaining ring 32 upward, the inlet and outlet mechanism 3 can be easily disassembled and replaced.

[0049] Reference Appendix Figure 5 As shown, the front and rear ends of the access channel 33 are fixedly installed with mounting bases 35, and the surface of the mounting bases 35 is provided with mounting holes 36.

[0050] As can be seen from the above, when the access channel 33 is attached to the ground, tools such as bolts or ground nails can be used to insert into the ground through the fixing hole 36, which can easily fix the fixing seat 35 to the ground, making it less likely for the access channel 33 to loosen or separate.

[0051] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
