Description

Technical Field

[0001] This invention belongs to the field of debris flow ecological protection technology, specifically, it relates to a debris flow ecological protection device. Background Technology

[0002] Debris flows are special types of floods carrying large amounts of solid materials such as mud, sand, rocks, and boulders, generated by sources such as torrential rain, glacial meltwater, and snowmelt in valleys or on mountain slopes. They are the product of a combination of natural and human factors. Because the solid materials they carry are extremely destructive, they pose a serious threat to people's lives and property. Therefore, debris flow protection is a necessary water conservancy project, effectively preventing the impact of natural disasters.

[0003] Currently, there are various types of devices for protecting against debris flows. For example, Chinese utility model patent CN219992260U discloses a debris flow protection device, which includes a connected base and columns. The columns have two members, with a rotatable crossbar between them. A protective rod is installed on the upper side of the crossbar, and the protective rod is made of elastic material. A protective column is installed on the lower side of the crossbar, and a rotatable sleeve is fitted on the outer side of the protective column. When a debris flow occurs, the device protects the debris flow. After the debris flow collides with the protective rod, the protective rod can rotate under the rotation of the crossbar, thus playing a certain buffering role. Furthermore, the sleeve rotates on the outer side of the protective column to block the debris in the debris flow, thereby playing a protective role against the debris flow. Although the protective device can provide some protection against debris flows, the impact force when the debris flow collides with it is relatively small, easily damaging the device. To address this issue, Chinese invention patent CN110670538A discloses a debris flow gully ecological engineering protection system. This system includes a protective unit and a counterweight unit. The protective unit includes a protective frame, drainage grid plate, barrier gate, strip slider, and sliding plate. The protective frame is slidably connected to the barrier gate, and the sliding plate is slidably mounted on the protective frame. Multiple return springs are connected to the sliding plate, which cushion the barrier gate, preventing debris flows from damaging the protection system. Additionally, the barrier gate is equipped with a flow-damping unit, which includes a flow-damping baffle connected to the barrier gate via a flow-damping support plate. A guide shaft is also connected to the flow-damping baffle, and a flow-damping compression spring is sleeved on the guide shaft. The flow-damping baffle is cushioned by the flow-damping compression spring when it moves, thus achieving the goal of blocking debris flows and providing a certain degree of protection.

[0004] However, although the above-mentioned debris flow protection devices can play a certain role in blocking debris flows and achieving ecological protection, the above-mentioned protection devices still have certain defects in use: because the height of the protection device is fixed, when the debris flow overflows the protection device, the device cannot block the debris flow, thus failing to play a protective role. Based on this, the present invention provides a debris flow ecological protection device to solve the shortcomings of the existing protection devices. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] To address the shortcomings of existing debris flow protection devices in blocking debris flows, the present invention adopts the following technical solution.

[0007] A debris flow ecological protection device includes a grid unit, which includes a grid baffle for blocking debris flows. A blocking unit is rotatably installed on the top of the grid unit. The blocking unit includes a blocking plate and a connecting plate. The blocking plate and the connecting plate are fixedly connected, and the connection between the blocking plate and the connecting plate is rotatably connected to the top of the grid baffle. When a debris flow occurs, the debris flow acts on the blocking plate, causing the blocking plate to rotate, which in turn causes the connecting plate to flip. After the connecting plate flips, it blocks the debris flow.

[0008] Preferably, in the above-mentioned debris flow ecological protection device, the bottom of the blocking plate is connected to a guide plate, which can guide the rocks in the debris flow to act on the surface of the blocking plate to drive the blocking plate to rotate. The connecting plate has a V-shaped structure, which can block the rocks in the debris flow when the connecting plate flips.

[0009] Preferably, in the above-mentioned debris flow ecological protection device, the blocking plate and the connecting plate are provided with protective nets, and the surfaces of the blocking plate and the connecting plate are also provided with reinforcing rods, which are used to prevent rocks in the debris flow from directly impacting the protective nets.

[0010] Preferably, the above-mentioned debris flow ecological protection device further includes a buffer unit, which is used to buffer the blocking unit when it rotates; the buffer unit includes an installation shell installed on one side of the grid baffle and a fixed shell connected to the installation shell. A support rod is slidably installed in the fixed shell, and one end of the support rod extends to the outside of the fixed shell and is connected to a support foot. A sliding block is slidably installed in the installation shell. A connecting rod is connected between the blocking plate and the sliding block. When the blocking plate rotates, the sliding block is driven to slide through the connecting rod. The sliding of the sliding block can drive the support rod to move the support foot. The support foot abuts against the ground, thereby generating a reaction force between the support and the ground, so that the blocking plate blocks the rocks in the debris flow.

[0011] Preferably, in the above-mentioned debris flow ecological protection device, a wedge is installed on the top of the support rod. The wedge is inside the fixed housing and is slidably connected to the fixed housing. The surface of the wedge is an inclined surface. An abutment is connected to the sliding block. The abutment abuts against the inclined surface of the wedge. The movement of the sliding block drives the abutment to move along the inclined surface, thereby driving the wedge to move the support rod.

[0012] Preferably, in the above-mentioned debris flow ecological protection device, the support rod is located inside the fixed shell and connected to a sliding plate, and a compression spring is sleeved on the support rod. One end of the compression spring is connected to the sliding plate, and the other end of the compression spring is connected to the inner wall of the fixed shell. When the support rod moves, the compression spring is compressed, and the compression spring generates a reaction force to buffer the blocking plate.

[0013] Preferably, in the above-mentioned debris flow ecological protection device, the barrier plate is provided with a free joint on the side near the mounting shell. The free joint and the sliding block are connected by a connecting rod. The two ends of the connecting rod are respectively connected to the free joint and the sliding block by ball joints. The connecting rod can rotate freely relative to the free joint and the sliding block. When the barrier plate rotates, the sliding block can be driven to slide inside the mounting shell through the connecting rod.

[0014] Preferably, the above-mentioned debris flow ecological protection device further includes a protection unit, which includes side plates symmetrically installed on both sides of the surface of the barrier plate, and a reinforcement component is installed between the side plates. The reinforcement component is located on the surface of the barrier plate to prevent rocks in the debris flow from directly impacting the barrier plate.

[0015] Preferably, in the above-mentioned debris flow ecological protection device, the reinforcement component includes a connecting plate installed on the side plate, and multiple protective rods are installed between the connecting plates. When a debris flow occurs, the protective rods block the rocks in the debris flow, preventing the rocks from directly impacting the surface of the blocking plate.

[0016] Preferably, in the above-mentioned debris flow ecological protection device, the grid unit further includes a fixing base for fixing the grid baffle. The bottom of the grid baffle is provided with an installation groove, and the two sides of the installation groove are provided with abutment parts. The top of the fixing base is connected to a connector, and the two sides of the connector are fixedly connected with mating parts. The grid baffle is inserted into the connector through the installation groove, and the abutment parts and the mating parts are mated and locked by bolts, thereby fixing the grid baffle on the fixing base.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The debris flow ecological protection device of the present invention includes a grid unit, which includes a grid baffle and a fixed base for fixing the grid baffle. A blocking unit is installed on the top of the grid baffle. The blocking unit includes a blocking plate and a connecting plate. The connection between the blocking plate and the connecting plate is rotatably connected to the top of the grid baffle. The bottom of the blocking plate in the present invention is connected to a guide plate, and the connecting plate has a V-shaped structure. When the debris flow acts on the blocking plate, it can drive the blocking plate to rotate, which in turn can drive the connecting plate to flip and block the debris flow. This avoids the problem that the protection device cannot protect the debris flow after the debris flow overflows the grid baffle in the prior art. In the present invention, the flipping of the connecting plate ensures the protection effect against the debris flow, thereby achieving the purpose of blocking the debris flow and realizing ecological protection.

[0018] (2) In the protective device of the present invention, buffer units are also provided on both sides of the grid baffle. The buffer unit includes a support rod set inside the fixed housing. The support rod extends to the outside and is connected to a support foot. A wedge is connected to the support rod. A connecting rod is connected to the baffle plate. A sliding block is connected to the end of the connecting rod. The sliding block is pressed against the wedge by an abutment. When the baffle plate rotates, the sliding block is driven to move by the connecting rod. During the movement of the sliding block, the abutment moves on the inclined surface of the wedge to drive the wedge to move the support rod. When the support rod moves, the support foot and the ground generate a force that reacts to the baffle plate, thereby supporting the baffle plate and improving the baffle plate's blocking effect on debris flow. In addition, a compression spring is also provided on the support rod. When the support rod moves, the compression spring contracts and generates a force that reacts to the baffle plate, thereby achieving a certain buffering effect when the baffle plate blocks debris flow and ensuring the blocking effect on debris flow.

[0019] (3) In the protective device of the present invention, the surface of the barrier plate is also provided with a protective unit. The protective unit includes side plates installed on both sides of the surface of the barrier plate and a reinforcing component located between the side plates. The reinforcing component includes multiple protective rods. When a debris flow occurs, the rocks in the debris flow directly act on the protective rods, avoiding the problem of the rocks in the debris flow acting on the surface of the barrier plate and causing damage to the barrier plate. Therefore, the setting of the protective unit in the present invention improves the service life of the barrier plate and ensures the blocking effect of the protective device on the debris flow.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0025] like Figure 1 as well as Figure 2 The diagram shown illustrates the effect of the assembled debris flow ecological protection device of this invention. In this embodiment, the debris flow ecological protection device is used to block debris flows, thereby achieving the purpose of ecological protection and avoiding the destructive consequences caused by debris flows. Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, this is a structural schematic diagram of the debris flow ecological protection device in this embodiment. The protection device in this embodiment includes a grid unit 100, which includes a fixed base 101 and a grid baffle 102. The fixed base 101 is preset in the trench of the installation area and fixed thereon. The grid baffle 102 is installed on the fixed base 101 to achieve fixation. In this embodiment, the grid baffle 102 can block the rocks in the debris flow and prevent the rocks from moving with the debris flow and causing damage.

[0026] In addition, to further ensure the stability of the grille baffle 102, such as Figure 4 as well as Figure 5 As shown, in this embodiment, a reinforcing plate 103 is fixedly connected to the grid baffle 102, and a support component 104 is also assembled on the reinforcing plate 103. The support component 104 supports the reinforcing plate 103 and the grid baffle 102, thereby ensuring the stability of the grid baffle 102 so as to block the debris flow.

[0027] like Figure 6 as well as Figure 7 As shown, in this embodiment, the grid baffle 102 and the fixed base 101 are detachably connected, which facilitates the assembly of the debris flow ecological protection device. In this embodiment, when assembling the debris flow ecological protection device, the fixed base 101 is first fixed in the trench of the installation area, and then the grid baffle 102 is installed on the fixed base 101. In this embodiment, a connector 101a is fixedly connected to the fixed base 101, and mating parts 101b are fixedly installed on both sides of the connector 101a. In addition, an installation groove 102a is opened at the bottom of the grid baffle 102, and the two sides of the installation groove 102a are provided with... The grid baffle 102 has an abutment member 102b. The grid baffle 102 is inserted into the connector 101a through the mounting groove 102a. After the abutment member 102b and the connecting member 101b are connected, bolt holes are opened on the abutment member 102b and the connecting member 101b. The bolts are used to fix the abutment member 102b and the connecting member 101b to each other, thereby fixing the grid baffle 102 to the fixed base 101. The mutual cooperation between the connector 101a and the mounting groove 102b and the locking effect of the bolts between the abutment member 102b and the connecting member 101b ensure the stability between the grid baffle 102 and the fixed base 101.

[0028] In this embodiment, to avoid the problem that the height limitation of the grid baffle 102 prevents it from providing adequate protection against debris flows, in this embodiment, as follows: Figure 1 as well as Figure 2As shown, in this embodiment, a blocking unit 200 is rotatably installed on the top of the grid baffle 102. When the debris flow overflows the grid baffle 102 during its movement, the debris flow impacts the blocking unit 200. After the impact, the blocking unit 200 rotates to further block the debris flow, thereby improving the blocking effect of the protective device on the debris flow.

[0029] like Figure 8 as well as Figure 9 As shown, in this embodiment, the blocking unit 200 includes a blocking plate 201 and a connecting plate 202. In this embodiment, the blocking plate 201 and the connecting plate 202 are fixedly connected, and the connection between the blocking plate 201 and the connecting plate 202 is rotatably connected to the top of the grid baffle 102. When the debris flow ecological protection device blocks the debris flow, the debris flow first collides with the blocking plate 201, causing the blocking plate 201 to rotate, thereby causing the connecting plate 202 to flip upward. When the connecting plate 202 flips upward, it can further block the debris flow, avoiding the problem that the grid unit 100 cannot block the debris flow after it overflows through the grid unit 100.

[0030] In addition, such as Figure 8 as well as Figure 9 As shown, in this embodiment, the bottom of the blocking plate 201 is integrally formed with a guide plate 204. The guide plate 204 has an arc-shaped structure and can guide the rocks in the debris flow to move to the surface of the blocking plate 201. When the rocks impact the blocking plate 201, they can drive the blocking unit 200 to rotate, thereby facilitating further protection against the debris flow. In this embodiment, the connecting plate 202 has a V-shaped structure. When the connecting plate 202 is flipped, the V-shaped structure can effectively block the rocks in the debris flow, thereby ensuring the protective effect of the debris flow ecological protection device in this embodiment.

[0031] In this embodiment, as Figure 8 As shown, in this embodiment, the blocking plate 201 and the connecting plate 202 are provided with protective nets. The protective nets block the rocks in the debris flow. In addition, in order to avoid the rocks from impacting the blocking unit 200 and causing damage to the protective nets, in this embodiment, reinforcing rods 203 are also fixedly installed on the surfaces of the blocking plate 201 and the connecting plate 202. In this embodiment, when the rocks in the debris flow impact the blocking unit 200, the reinforcing rods 203 are used to block the rocks in the debris flow, thus avoiding the problem of the rocks in the debris flow directly impacting the protective nets and causing damage to the protective nets.

[0032] In this embodiment, to further ensure the blocking effect of the debris flow ecological protection device on debris flow, the rotational resistance of the blocking unit 200 is increased to ensure the blocking effect of the blocking unit 200 on debris flow. Figure 4 , Figure 6as well as Figure 10 As shown, in this embodiment, buffer units 300 are provided on both sides of the grid baffle 102. When the blocking unit 200 rotates, the buffer units 300 buffer the blocking unit 200, thereby further ensuring the blocking effect of the blocking unit 200 on the debris flow. In this embodiment, as shown... Figures 10-12 As shown, in this embodiment, the buffer unit 300 includes a mounting housing 301 and a fixed housing 302. The mounting housing 301 and the fixed housing 302 are in communication. In this embodiment, a sliding block 301a is slidably mounted inside the mounting housing 301. In this embodiment, a free joint 201a is connected to the side of the blocking plate 201 near the mounting housing 301. In this embodiment, a connecting rod 304 is installed between the free joint 201a and the sliding block 301a. In this embodiment, both ends of the connecting rod 304 are respectively connected to the ball joint 201a and the sliding block 301a via a ball joint. Therefore, both ends of the connecting rod 304 are respectively relative to the free joint 201a. 1a and sliding block 301a can rotate freely. In this embodiment, when the blocking plate 201 rotates towards the side closer to the mounting housing 301, the blocking plate 201 can drive the sliding block 301a to slide inside the mounting housing 301 through the connecting rod 304. In this embodiment, a buffer spring 301b is also provided inside the mounting housing 301. One end of the buffer spring 301b is connected to the sliding block 301a, and the other end is connected to the inner wall of the mounting housing 301. In this embodiment, when the blocking plate 201 rotates and drives the sliding block 301a to move inside the mounting housing 301 through the connecting rod 304, the buffer spring 301b plays a buffering role.

[0033] In addition, such as Figure 11 as well as Figure 12As shown, in this embodiment, multiple support rods 303 are slidably installed inside the fixed housing 302. The support rods 303 are slidably installed in the fixed housing 302, and their ends extend to the outside of the fixed housing 302 and are connected to support feet. The support feet abut against the ground in the installation area of ​​the debris flow ecological protection device. In this embodiment, a sliding plate 305 is installed on the support rod 303, and a compression spring 308 is sleeved on the support rod 303. One end of the compression spring 308 is connected to the sliding plate 305, and the other end of the compression spring 308 is connected to the inner wall of the fixed housing 302. In this embodiment, a wedge block 306 is connected to the end of the support rod 303 located inside the fixed housing 302. The surface of the wedge block 306 is an inclined surface, and the wedge block 306 is slidably connected to the fixed housing 302. Additionally, an abutment member 307 is connected to the sliding block 301a located inside the mounting housing 301. 07 extends into the fixed housing 302 and abuts against the inclined surface of the wedge 306. In this embodiment, when the blocking plate 201 rotates and drives the sliding block 301a to move via the connecting rod 304, the sliding block 301a drives the abutment 307 to move. When the abutment 307 moves along the inclined surface of the wedge 306, it drives the wedge 306 to slide within the fixed housing 302, thereby driving the support rod 303 and the sliding plate 305 to move. The compression spring 308 on the support rod 303 is deformed by pressure. The compression spring 308 generates a reaction force on the blocking plate 201 through the support rod 303, the wedge 306, the abutment 307, the sliding block 301a, and the connecting rod 304. When the debris flow impacts the blocking plate 201, it buffers the impact, thereby ensuring the protective effect of the blocking plate 201 and avoiding damage to the blocking plate 201 due to rigid collision with the debris flow. On the other hand, as the support rod 303 moves, it drives the support foot to move, and the support foot abuts against the ground, which further improves the support effect. The force between the support foot and the ground reacts to the blocking plate 201, which also ensures the blocking effect of the blocking plate 201 on the debris flow.

[0034] In this embodiment, when the debris flow acts on the baffle plate 201, the baffle plate 201 rotates, thereby causing the connecting plate 202 to flip. The flipping of the connecting plate 202 further blocks the debris flow, preventing the protective device from failing to block the debris flow after it overflows the grid baffle 102. Furthermore, when the baffle plate 201 rotates in this embodiment, it drives the support rod 303 inside the fixed housing 302 to move, thereby compressing the compression spring 308. Due to its elasticity, the compression spring 308 reacts to the baffle plate 201, so that the baffle plate 201 acts as a buffer while blocking the rocks in the debris flow, preventing the baffle plate 201 from being damaged. In addition, the baffle plate 201 can effectively block the rocks in the debris flow due to the reaction force of the compression spring 308, ensuring the protective effect of the protective device in this embodiment.

[0035] Furthermore, in this embodiment, since the rocks in the debris flow directly impact the baffle plate 201 during a debris flow, even with reinforcing rods 203 installed in the baffle plate 201, it is difficult to prevent damage to the baffle plate 201 caused by the debris flow. Therefore, in this embodiment, to further prevent the baffle plate 201 from being damaged by the debris flow, as follows... Figures 13-16 As shown, a protective unit 400 is also installed on the surface of the barrier plate 201. The protective unit 400 protects the barrier plate 201 and prevents the barrier plate 201 from being damaged by mudslides.

[0036] In this embodiment, the protective unit 400 includes side plates 401 disposed on both sides of the surface of the barrier plate 201 and a reinforcing component 402 installed between the side plates 401. In this embodiment, the reinforcing component 402 includes a connecting plate 402a and a protective rod 402b installed between the connecting plates 402a. The two ends of the protective rod 402b are connected to the connecting plate 402a and fixed between the side plates 401 by the connecting plate 402a. In this embodiment, multiple sets of protective rods 402b are provided. When a debris flow occurs, the rocks in the debris flow directly act on the protective rods 402b, avoiding direct impact of the rocks on the barrier plate 201, thereby avoiding damage to the barrier plate 201, further ensuring the service life of the barrier plate 201, and improving the protective effect of the debris flow ecological protection device.

It should not be construed that the specific implementation of the present invention is limited to these descriptions.
