Description

Technical Field

[0001] This utility model belongs to the technical field of soil and water conservation equipment, and specifically relates to an anchoring device and protective net assembly for soil and water conservation. Background Technology

[0002] In the fields of soil and water conservation, slope ecological restoration and ecological engineering construction, soil and water conservation protection nets are commonly used protective equipment. They often solve problems such as soil erosion, slope instability and difficulty in vegetation survival through the dual effects of physical interception and ecological synergy. They are an important measure that takes into account both engineering protection and ecological restoration.

[0003] Protective netting is typically fixed to the slope using ground nails or anchors, providing tensile support to the surface soil. Some existing technologies improve the anchors to enhance the stability of the connection between the anchors and the ground. For example, Chinese invention patent application (CN116676962A) discloses an anchoring device for slope protection netting and a slope protection netting itself. This patent includes multiple anchoring devices and a slope protection netting body, with the slope protection netting body connected to the winding grooves of each of the anchoring devices. When fixing the anchoring device, firstly, the fixing rod is inserted into the soil layer. The positioning ring and the outer anchor sleeve are slidably engaged to limit the movement of the outer anchor sleeve. The cap is then struck to simultaneously insert the outer anchor sleeve and the inner anchor body into the soil layer. Then, the cap is removed. Using the threaded connection structure between the inner anchor body and the outer anchor sleeve, the inner anchor body is rotated by rotating the operating component. As it rotates, the inner anchor body gradually penetrates deeper into the ground to extend the length of the anchoring device embedded in the ground, further increasing the gripping force between the device and the ground, ensuring the overall stability of the fixation, and thus improving the protective effect of the slope protection net.

[0004] In the aforementioned prior art, during the installation of the anchoring device, the cap must first be removed, then the rotating operating component is engaged with the inner anchor rod body, and finally the inner anchor rod body is rotated by the rotating operating component. This makes the installation of the anchoring device cumbersome, and the rotating operating component and the inner anchor rod body are separate structures that need to be stored and carried separately, making movement inconvenient.

[0005] The inner anchor body and the outer anchor sleeve are connected by threads. By rotating the inner anchor body, it is further inserted into the soil layer. Although this can enhance the gripping force between the inner anchor body and the soil, the contact form between the inner anchor body and the soil is an axial contact surface, lacking an effective radial contact surface, resulting in a limited constraint effect between the anchor and the soil. Utility Model Content

[0006] One objective of this invention is to provide an anchoring device for soil and water conservation, comprising an anchoring sleeve, an anchoring rod threadedly connected to the anchoring sleeve, a tapered head at the bottom end of the anchoring rod, a cavity with a top opening along the axial direction of the anchoring rod, a guide key along the axial direction of the inner wall of the cavity, a sliding rod that slides within the cavity, a guide groove corresponding to the sliding key on the side wall of the sliding rod, and a baffle at the top of the sliding rod. Furthermore, the anchoring rod above the conical head is provided with a helical anchor wing, which is housed within the anchoring sleeve. The conical head is located outside the bottom of the anchoring sleeve, and its upper end face is in contact with the bottom of the anchoring sleeve. Rotating the anchoring rod causes the helical anchor wing to rotate and move to the outside of the bottom opening of the anchoring sleeve. Furthermore, an anchoring plate is fitted onto the upper outer side of the anchoring sleeve, and a first fixing hole is formed on the anchoring plate. The first fixing hole is used to insert a first ground nail to fix the anchoring plate to the ground. Furthermore, the baffle is adapted to the top opening of the anchoring sleeve, and the anchoring sleeve is provided with a supporting boss. The supporting boss is evenly distributed along the circumference of the anchoring sleeve and is used to support the baffle. The bottom end of the sliding rod is spaced apart from the inner bottom surface of the cavity. Furthermore, the top surface of the baffle protrudes axially beyond the outer side of the top opening of the anchor sleeve, and the baffle is provided with a fixing hole that passes through both sides radially. Furthermore, the anchoring sleeve has an annular flange at its inner center, and the inner annular surface of the annular flange has an internal thread. The anchoring rod located above the helical anchor wing has an external thread, and the anchoring rod is threadedly connected to the annular flange.

[0007] Another objective of this utility model is to provide a protective net assembly for soil and water conservation, comprising a protective net, an anchoring device, and a flexible connecting member. The anchoring device is connected to the flexible connecting member and forms a rectangular frame. The protective net is disposed within the rectangular frame, and the anchoring device is located at the corner of the rectangular frame. The flexible connecting member is used to connect the spaced anchoring devices, and the anchoring device adopts the aforementioned anchoring device.

[0008] Furthermore, the flexible connecting member is composed of multiple connecting plates hinged together, the anchor plate has a rectangular structure, and the anchor plate is hinged to the connecting plate.

[0009] Furthermore, the connecting plate has a first connecting lug with a spacing of D1 on one side and a second connecting lug with a spacing of D2 on the other side. The anchor plate has a third connecting lug with a spacing of D3 on all four sides, where D3 > D2 > D1. The adjacent connecting plates and the connecting plate and the anchoring device are connected by connecting pins.

[0010] Furthermore, the connecting plate has a second fixing hole in the center, which is used to insert a second ground nail to fix the connecting plate to the ground.

[0011] Compared with the shortcomings and deficiencies of the prior art, the present invention has the following beneficial effects.

[0012] This invention provides an anchoring device for soil and water conservation. The anchor rod has a hollow cavity along its axial direction, housing a sliding rod. The sliding rod engages with the anchor rod via a guide key and a guide groove, forming an axial sliding fit. A baffle at the top of the sliding rod protrudes from the top opening of the anchor sleeve. When rotating the anchor rod, the baffle is held to apply rotational force, which is efficiently transmitted to the anchor rod through the sliding rod. Both the sliding rod and the anchor rod are housed within the anchor sleeve. Compared to a separate structure, this anchoring device is more convenient to carry, move, and install.

[0013] A helical anchor wing is installed above the conical head at the bottom of the anchor rod. When the anchor rod moves downward through the threaded drive, the helical anchor wing extends from the bottom of the anchor sleeve and drills into the deep soil. Compared with the circumferential contact surface in the prior art, the helical structure of the helical anchor wing forms a large-area radial engagement with the deep soil, significantly increasing the contact area with the soil. At the same time, the deeper soil has a higher density, resulting in stronger friction and interlocking force between the helical anchor wing and the soil, forming a stable deep anchoring system and effectively solving the problem of insufficient radial restraint in the prior art. The dual anchoring structure design enhances the stable connection between the anchoring device and the soil.

[0014] This utility model also provides a protective net assembly for soil and water conservation. The flexible connecting component is composed of multiple connecting plates hinged together. The hinged structure can rotate freely around the connecting pin and can adjust the angle of the connecting plate according to the undulation and slope of the ground, avoiding the problem of local suspension caused by the traditional rigid frame due to terrain mismatch. The connecting plate is fixed by a second ground nail, so that the connecting plate is closely attached to the ground. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example 1 Reference Figures 1-4 This embodiment discloses an anchoring device for soil and water conservation, including an anchoring sleeve 100 and an anchoring rod 200. The anchoring rod 200 is inserted into the anchoring sleeve 100 and is threadedly connected to the anchoring sleeve 100. After the anchoring sleeve 100 is inserted into the ground and fixed, the anchoring rod 200 is rotated to insert it into a deeper soil layer, thereby increasing the stable connection effect between the anchoring device and the soil.

[0026] The anchoring sleeve 100 adopts a cylindrical structure with vertically connected components. The anchoring sleeve 100 has a top opening and a bottom opening. An annular flange 110 is provided in the middle of the interior of the anchoring sleeve 100. The inner arc-shaped surface of the annular flange 110 is provided with an internal thread for threaded connection with the anchor rod 200. The annular flange 110 divides the anchoring sleeve 100 into an upper cylindrical body and a lower cylindrical body with vertically connected components. An anchoring plate 120 is provided on the top of the outer side of the anchoring sleeve 100. The anchoring plate 120 is perpendicular to the axis of the anchoring sleeve 100. The anchoring plate 120 is provided with a first fixing hole. Multiple first fixing holes are evenly opened around the center of the anchoring sleeve 100. In this embodiment, the number of first fixing holes is 4. The first fixing holes are used to insert ground nails to stably connect the anchoring plate 120 to the ground.

[0027] The bottom end of the anchor rod 200 is provided with a tapered head 210, the tip of which points downwards. The top surface size of the tapered head 210 is adapted to the anchor sleeve 100. The lower part of the anchor rod 200 is provided with a helical anchor wing 220, which can be accommodated in the lower part of the anchor sleeve 100. The upper part of the anchor rod 200 is provided with an external thread 230 for threaded engagement with the annular flange 110.

[0028] Anchor rod 200 has a cylindrical cavity extending axially and coaxial with it. The top of the cavity is open, and a sliding rod 300 passes through the cavity, so that the sliding rod 300 and the anchor rod 200 slide in axial direction. Specifically, the inner wall of the cavity of anchor rod 200 is provided with a guide key 240 extending axially. Multiple guide keys 240 are evenly distributed around the inner wall of anchor rod 200. The sliding rod 300 is provided with a corresponding guide groove 320. The guide key 240 is embedded in the guide groove 320 and slides in slidably with the guide groove 320.

[0029] The top of the sliding rod 300 is provided with a baffle 310, which slides in cooperation with the upper cylinder of the anchor sleeve 100. The baffle 310 is used to drive the anchor rod 200 to rotate through the sliding rod 300, so as to allow the spiral anchor wing 220 on the anchor rod 200 to pass through into the soil below the anchor sleeve 100, thereby further increasing the stability of the connection between the anchoring mechanism and the soil.

[0030] The baffle 310 has through mounting holes 330 on both sides along the radial direction. Rods can be inserted into the mounting holes 330. The rods located on both sides of the mounting holes 330 drive the baffle 310 to rotate, thereby driving the anchor rod 200 to rotate through the sliding rod 300.

[0031] The upper cylinder inside the anchoring sleeve 100 is provided with a support boss 140. Multiple support bosses 140 are evenly distributed along the inner circumference of the upper cylinder or connected to form an annular support boss 140. The support bosses 140 are used to support and limit the baffle 310. When the support boss 140 contacts the baffle 310, the top surface of the baffle 310 is located outside the anchoring sleeve 100, which facilitates the removal of the baffle 310. At the same time, the bottom of the sliding rod 300 is spaced from the inner bottom surface of the support rod. When the baffle 310 is struck, the force can be transmitted through the baffle 310 to the anchoring sleeve 100 and the conical head 210 in sequence, thereby inserting the entire anchoring device into the ground.

[0032] The above settings can achieve the following: Before anchoring, (refer to) Figure 1 Anchor rod 200 is inserted into anchor sleeve 100. The bottom of anchor sleeve 100 abuts against the top surface of conical head 210. Baffle 310 is in contact with support boss 140 inside anchor sleeve 100. The top surface of baffle 310 protrudes outside anchor sleeve 100. Sliding rod 300 is inserted into anchor rod 200. The bottom of sliding rod 300 is spaced from the bottom surface of the cavity of anchor rod 200.

[0033] With the axis of the anchor sleeve 100 perpendicular to the ground, the top surface of the baffle 310 is struck using a hammer or similar tool. The impact force is transmitted through the baffle 310 and the support boss 140 to the anchor sleeve 100, and finally acts on the conical head 210. Under the action of the impact force, the conical head 210 and the anchor sleeve 100 gradually insert into the soil until the anchor plate 120 on the upper outer side of the anchor sleeve 100 is in contact with the ground.

[0034] The first ground nail 130 is inserted into the first fixing hole of the anchor plate 120, and the first ground nail 130 is driven into the ground completely with a hammer. The fixing effect of the first ground nail 130 on the anchor plate 120 further enhances the connection stability between the anchor sleeve 100 and the ground, and at the same time prevents the anchor sleeve 100 from rotating.

[0035] Since the sliding rod 300 and the anchor rod 200 are relatively rotated together via the guide key 240 and the guide groove 320, the operator can hold the baffle 310 and apply a rotational force. The rotational force is transmitted through the baffle 310 to the sliding rod 300, and then to the anchor rod 200, causing the anchor rod 200 to rotate around its own axis. When the anchor rod 200 rotates, its upper external thread 230 engages with the internal thread of the annular flange 110 of the anchor sleeve 100. Since the anchor sleeve 100 is fixed by the anchor plate 120 and the first ground nail 130, the anchor rod 200 moves axially downward under the action of the thread. As the anchor rod 200 moves downward, the spiral anchor wing 220 at its lower part gradually extends from the bottom opening of the anchor sleeve 100 into the outer soil. During the rotation, the spiral anchor wing 220 continuously drills into the deep soil through the spiral meshing action with the soil, further driving the anchor rod 200 to extend into the depth of the soil to complete the fixation of the anchoring device.

[0036] Example 2 This embodiment discloses a protective net assembly for soil and water conservation. The protective net assembly includes an anchoring device, a flexible connecting member, and a protective net 500. The anchoring device adopts the anchoring device in Embodiment 1. The protective net 500 is provided with anchoring devices around its perimeter. The anchoring devices are connected to each other by the flexible connecting member, so that the anchoring devices and the flexible connecting member are connected to form a rectangular frame. The protective net 500 is installed inside the rectangular frame.

[0037] The flexible connecting component is composed of multiple connecting plates 400 hinged together. Specifically, two first connecting ears 410 are arranged at intervals on one side of the connecting plate 400, and the first connecting ears 410 on both sides are symmetrically arranged along the center line of the connecting plate 400. The distance between the first connecting ears 410 is D1. Two second connecting ears 420 are arranged at intervals on the other side of the connecting plate 400, and the second connecting ears 420 on both sides are symmetrically arranged along the center line of the connecting plate 400. The distance between the second connecting ears 420 is D2, where D2 > D1.

[0038] Both the first connecting ear 410 and the second connecting ear 420 are provided with through holes. When adjacent connecting plates 400 are connected, the first connecting ear 410 of one side of the connecting plate 400 and the through hole of the second connecting ear 420 of the other side of the connecting plate 400 are aligned and connected by a connecting pin.

[0039] Fixing rods 440 are provided on both sides of the connecting plate 400 along its length. The fixing rods 440 are used to fix the protective net 500.

[0040] In the anchoring device, the anchoring plate 120 has a rectangular structure, and the vertical sidewalls around it are provided with third connecting ears 150. The two third connecting ears 150 on each sidewall are symmetrically arranged on both sides of the center line of the anchoring plate 120, and the distance between the two third connecting ears 150 is D3, where D3 > D2.

[0041] The third connecting ear 150 is provided with a through hole. The first connecting ear 410 or the second connecting ear 420 of the connecting plate 400 is aligned and connected with the through hole of the third connecting ear 150 of the anchor plate 120, and connected by a connecting pin.

[0042] The above settings can achieve the following: Take multiple connecting plates 400, align the first connecting ear 410 of one connecting plate 400 with the second connecting ear 420 of another connecting plate 400, so that the through holes on the connecting ears are connected, then insert the connecting pin into the aligned connecting ear, tighten the nut at the end of the connecting pin to complete the fixation, repeat the operation in sequence, and assemble a flexible connecting section that meets the requirements of the rectangular frame side length.

[0043] The two ends of the assembled flexible connecting section are connected to the anchor plate 120 of the anchoring device, so that the connecting ears (first connecting ear 410 or second connecting ear 420) at the end of the connecting plate 400 are aligned with the third connecting ear 150 of the anchor plate 120. The connecting pin is inserted and the nut is tightened to form the four corners of the rectangular frame, and finally the anchoring device and the flexible connecting component are enclosed to form a complete rectangular frame.

[0044] Lay the protective net 500 flat inside the rectangular frame, and then fit the edge mesh of the protective net 500 onto the fixing rod 440 of the connecting plate 400 one by one, ensuring that the protective net 500 is free of wrinkles and excessive stretching within the rectangular frame.

[0045] A second ground nail 450 is inserted into the second fixing hole 430 in the center of each connecting plate 400. The second ground nail 450 is then driven completely into the ground using a tool. The second ground nail 450 restricts the horizontal displacement and vertical lifting of the connecting plate 400, further enhancing the fit between the flexible connecting component and the ground.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
