Technical Field

[0001] The present application relates to the technical field of retaining walls, and more specifically, to a retaining device for soil and water conservation. Background Art

[0002] Soil and water conservation retaining devices, also known as slope protection projects or slope protection facilities, are mainly used to prevent soil erosion and stabilize hillsides.

[0003] The document with the prior art publication number CN219931048U provides a retaining device for soil and water conservation. In the related technology of the device, through the design of fixed columns and extension columns, the bottom plate is placed on the ground, the fixed columns are inserted into the ground, the rotating knob is turned to extend the extension columns outward, and the extension columns are inserted into the soil layer in a direction perpendicular to the fixed columns, thereby improving the stability of the fixed columns and further improving the stability of the device. Compared with the existing retaining devices, the present retaining device significantly improves stability.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: although the device can adjust the height of the accumulated soil layer through the lifting plate, the sliding of the soil layer on the slope cannot be controlled, and the directional height plate cannot be effectively self-adjusted for blocking.

[0005] In view of this, we propose a soil retaining device for soil and water conservation. Utility Model Content

[0006] In order to improve the problems raised in the above background technology, the present application provides a soil retaining device for soil and water conservation.

[0007] The retaining device for soil and water conservation provided in this application adopts the following technical solution:

[0008] A soil retaining device for soil and water conservation, comprising:

[0009] Base plate;

[0010] A retaining frame is fixedly connected to one end of the base plate;

[0011] A long pitch lead screw is rotatably connected inside the retaining frame;

[0012] The extension plate is slidably connected inside the retaining frame and is adapted to the thread of the long pitch lead screw;

[0013] The transmission gear shaft is rotatably connected inside the extension plate and is slidably connected with the long pitch lead screw;

[0014] The turning plate with the gear plate is sleeved and installed, hingedly installed at one end of the extension plate, and meshes with the transmission gear shaft for transmission.

[0015] By adopting the above technical scheme, the soil that falls off the slope is used to squeeze the tilted pressure plate. When the pressure plate squeezed by the soil layer rotates, the gear plate and the transmission gear shaft are meshed and transmitted. The rotating transmission gear shaft drives the coaxial plug-in limited long-pitch screw to rotate coaxially, so that the rotating long-pitch screw drives the external thread limit and the extension plate sliding in the retaining frame to automatically rise and adjust, so as to synchronously raise and protect the earth that has fallen and accumulated on one side of the retaining frame.

[0016] As an optional solution to the technical solution of the present application document, a shovel plate is slidably connected in the through groove opened in the middle of the base plate, and an engaging groove that can engage with a transmission gear rotatably connected to the surface of the base plate is opened on one side of the shovel plate, and a pressure plate is fixedly connected to the outside of the transmission gear, and the pressure plate arranged in a U-shaped structure is sleeved on the outside with a ground nail column, and a plurality of mounting holes for inserting fixed piles are opened at one end of the base plate.

[0017] By adopting the above technical solution, when the base plate is installed and fixed by tamping with the ground nail column, the sunken ground nail column drives the external sliding limit pressure plate to flip over, so that the transmission gear fixedly installed at one end engages with the shovel plate for transmission, and the shovel plate stored in the base plate is pushed out, and the bottom of the slope soil layer is inserted and limited, thereby ensuring the stability of the retaining frame installation. At the same time, when the fixed pile is inserted into the installation hole of the base plate, the extended shovel plate can be abutted and limited to avoid the shovel plate from being recovered, thereby improving the stability of the device installation.

[0018] As an optional solution of the technical solution of this application document, a seam blocking plate is hingedly installed on one side of the retaining frame through an elastic hinge, the other end of the seam blocking plate is rotatably connected to a roller, and the outside of the retaining frame is coated with an anti-corrosion coating.

[0019] By adopting the above technical solution, the gap between the extension plate and the retaining frame can be covered by the gap blocking plate to prevent soil debris from entering and affecting the extension and retraction of the extension plate.

[0020] As an optional solution to the technical solution of the present application, an intercepting plate capable of limiting the flipping angle of the flip plate is fixedly connected to one side of the extension plate by bolts, and a screw sleeve capable of threadably matching with a long-pitch screw rod is fixedly connected to the rotating groove opened in the extension plate by bolts.

[0021] By adopting the above technical solution, the intercepting plate can be used to abut and limit the flipping pressure plate, so as to avoid excessive flipping of the flipping pressure plate and affect the soil retaining effect of the device.

[0022] As an optional solution to the technical solution of the present application document, the transmission gear shaft includes a prism that can be slidably adapted to the long pitch screw rod, and one end of the prism is fixedly connected to a passive gear that can mesh and transmit with the gear plate in the middle of the flap plate, and the passive gear is rotatably connected to the extension plate.

[0023] By adopting the above technical solution, the prism and the long pitch lead screw are slidably matched to facilitate the coaxial rotation of the long pitch lead screw and the transmission gear shaft, so that when the transmission pressure plate flips, the extension plate is driven to rise synchronously.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The present application utilizes the soil that has fallen off the slope to squeeze the tilted pressure plate. When the pressure plate squeezed by the soil layer rotates, the gear plate and the transmission gear shaft are meshed and transmitted. The rotating transmission gear shaft drives the coaxial plug-in limit long-pitch screw rod to rotate coaxially, so that the rotating long-pitch screw rod drives the external thread limit and the extension plate that slides in the retaining frame to automatically rise and adjust, thereby synchronously raising and protecting the earth that has fallen off and accumulated on one side of the retaining frame.

[0026] 2. The present application utilizes the soil that has fallen off the slope to squeeze the tilted pressure plate. When the pressure plate squeezed by the soil layer rotates, the gear plate and the transmission gear shaft are meshed and transmitted. The rotating transmission gear shaft drives the coaxial plug-in limit long-pitch screw rod to rotate coaxially, so that the rotating long-pitch screw rod drives the external thread limit and the extension plate sliding in the retaining frame to automatically rise and adjust, thereby synchronously raising and protecting the earth that has fallen off and accumulated on one side of the retaining frame.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] Reference Figure 1 and Figure 2 A soil retaining device for soil and water conservation in the embodiment of the present application includes:

[0036] Base plate 1;

[0037] A retaining frame 2 is fixedly connected to one end of the base plate 1;

[0038] A long pitch screw rod 3 is rotatably connected to the interior of the retaining frame 2;

[0039] The extension plate 4 is slidably connected to the interior of the retaining frame 2 and threadably adapted to the long pitch lead screw 3;

[0040] The transmission gear shaft 5 is rotatably connected to the extension plate 4 and is slidably connected to the long pitch lead screw 3;

[0041] The turning plate 6 with a gear plate sleeved thereon is hingedly mounted on one end of the extension plate 4 and meshes with the transmission gear shaft 5 for transmission.

[0042] The retaining device for soil and water conservation utilizes the soil falling off the slope to squeeze the tilted pressure plate 6. When the pressure plate 6 squeezed by the soil layer rotates, the gear plate and the transmission gear shaft 5 are meshed and transmitted. The rotating transmission gear shaft 5 drives the coaxial plug-in limited long-pitch screw rod 3 to rotate coaxially, so that the rotating long-pitch screw rod 3 drives the external thread limited and sliding extension plate 4 in the retaining frame 2 to automatically rise and adjust, so that the earth that falls off and accumulates on one side of the retaining frame 2 is synchronously raised for protection.

[0043] Reference Figure 3 and Figure 1In the retaining device for soil and water conservation recorded in the embodiment of the present application, a shovel plate 11 is slidably connected in the through groove opened in the middle of the base plate 1, and an engaging groove 13 that can mesh with a transmission gear 12 rotatably connected to the surface of the base plate 1 is opened on one side of the shovel plate 11, and a pressure plate 14 is fixedly connected to the outside of the transmission gear 12. The outside of the pressure plate 14 arranged in a U-shaped structure is sleeved with a ground nail column 15, and one end of the base plate 1 is opened with a plurality of installation holes for inserting fixed piles.

[0044] The retaining device for soil and water conservation uses the ground nail column 15 to ram and fix the base plate 1. The sunken ground nail column 15 drives the external sliding limit pressure plate 14 to limit and flip, so that the transmission gear 12 fixedly installed at one end engages and transmits with the shovel plate 11, and the shovel plate 11 received in the base plate 1 is pushed out, and the bottom of the slope soil layer is inserted and limited, thereby ensuring the stability of the installation of the retaining frame 2. At the same time, when a fixed pile is inserted into the installation hole of the base plate 1, the extended shovel plate 11 can be abutted and limited to avoid the shovel plate 11 from being recovered, thereby improving the stability of the device installation.

[0045] Reference Figure 4 and Figure 1 In the retaining device for soil and water conservation recorded in the embodiment of the present application, a retaining plate 21 is hingedly installed on one side of the retaining frame 2 through an elastic hinge, and a roller 22 is rotatably connected to the other end of the retaining plate 21, and the outside of the retaining frame 2 is coated with an anti-corrosion coating.

[0046] The retaining device for soil and water conservation can cover the sliding gap between the extension plate 4 and the retaining frame 2 by using the retaining plate 21 to prevent soil debris from entering and affecting the extension and retraction of the extension plate 4.

[0047] Reference Figure 5 and Figure 1 In the retaining device for soil and water conservation recorded in the embodiment of the present application, an intercepting plate 41 capable of limiting the flipping angle of the flipping plate 6 is fixedly connected to one side of the extension plate 4 by bolts, and a screw sleeve 42 capable of threadably matching with the long-pitch screw rod 3 is fixedly connected to the rotating groove opened in the extension plate 4 by bolts.

[0048] The retaining device for soil and water conservation can abut and limit the turned over pressure plate 6 by using the interception plate 41, so as to prevent the pressure plate 6 from turning over too much and affecting the retaining effect of the device.

[0049] Reference Figure 6 and Figure 5 In the soil retaining device for soil and water conservation recorded in the embodiment of the present application, the transmission gear shaft 5 includes a prism 51 that can be slidably adapted to the long-pitch screw rod 3, and one end of the prism 51 is fixedly connected to a passive gear 52 that can mesh and drive with the gear plate in the middle of the flap plate 6, and the passive gear 52 is rotatably connected to the extension plate 4.

[0050] The retaining device for soil and water conservation utilizes the sliding cooperation between the prism 51 and the long pitch screw rod 3 to facilitate the coaxial rotation of the long pitch screw rod 3 and the transmission gear shaft 5, so that when the transmission pressure plate 6 turns over, the extension plate 4 is driven to rise synchronously.

[0051] Working principle: When the operator tamps the ground nail column 15 and fixes the base plate 1 to the slope for retaining soil, the sunken ground nail column 15 drives the external sliding limit pressure plate 14 to limit and flip, so that the transmission gear 12 fixedly installed at one end engages and transmits with the shovel plate 11, and the shovel plate 11 stored in the base plate 1 is pushed out, and the bottom of the slope soil layer is inserted and limited. Then, a fixed pile is inserted into the installation hole of the base plate 1 to further fix the position of the base plate 1, and the fixed pile can abut and limit the extended shovel plate 11;

[0052] When the soil that falls off the slope squeezes the inclined pressure plate 6, and the pressure plate 6 squeezed by the soil layer rotates, the gear plate and the transmission gear shaft 5 are meshed and transmitted, and the rotating transmission gear shaft 5 drives the coaxial plug-in limited long-pitch screw rod 3 to rotate coaxially, so that the rotating long-pitch screw rod 3 drives the external thread limit and the extension plate 4 sliding in the retaining frame 2 to automatically rise and adjust, so as to synchronously raise and protect the earth that has fallen off and accumulated on one side of the retaining frame 2.
