Description

Technical Field

[0001] This utility model belongs to the field of sand barrier technology, and in particular, it is a connecting and fixing device for sand barriers used for sand prevention and control. Background Technology

[0002] Sand barriers are an effective engineering measure for reducing wind speed and fixing sand surfaces. The mesh sand barrier is tied to the surface of the column with steel wire to reduce wind speed and fix the sand surface. A connecting and fixing device is required. When using the existing connecting and fixing device, it is usually extended into the sand body to achieve installation and fixation. Since the sand body has low mutual adhesion, the connecting and fixing device is very easy to become unstable, which reduces the installation and fixing effect of the connecting and fixing device on the sand barrier.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN215210957U) entitled "A Connection and Fixing Device for Sand Barriers in Sand Control and Afforestation," which includes a fixing cover. A first fixing mechanism extending to the top of the fixing cover is fixedly installed on the inner top wall of the fixing cover. Vertical plates are fixedly installed on the front, back, and left and right sides of the fixing cover. A second fixing mechanism is movably installed inside the vertical plates. A first threaded rod, one end of which passes through the second fixing mechanism and is movably connected to the fixing cover, is movably installed on the opposite side of the second fixing mechanism. The second fixing mechanism includes a movable block. This connection and fixing device for sand barriers in sand control and afforestation has the function of adjusting the position of the auxiliary fixing rod. When fixing the sand barrier in the sand, the position of the auxiliary fixing rod can be adjusted according to the softness of the sand. The farther the auxiliary fixing rod is from the fixing cover, the more stable the fixation, preventing the sand barrier from being blown down by the wind and improving the efficiency of sand control and afforestation. However, this device does not consider that due to the low adhesion between sand particles, the device extending into the sand body is not easy to erect, resulting in unstable support of the connection and fixing device and reducing the installation and fixing effect of the connection and fixing device on the sand barrier. Utility Model Content

[0004] The purpose of this utility model is to provide a connection and fixing device for sand barriers used in sand prevention and control, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connecting and fixing device for sand barriers used in sand prevention and control, comprising a support plate and a clamping assembly for sand barriers used in sand prevention and control. The clamping assembly is disposed on the top surface of the support plate. A hollow insert post is welded to the bottom surface of the support plate. A conical block for sand barriers used in sand prevention and control is welded to the top surface of the insert post. A fixing plate is welded to the inner wall of the insert post. A rotating rod is rotatably connected to the top surface of the fixing plate. An active bevel gear is welded to the bottom surface of the rotating rod. The active bevel gear meshes with a driven bevel gear. A connecting rod is fixedly connected to the side of the driven bevel gear. Two symmetrically arranged threaded rods with reverse threads are welded to the end face of the connecting rod. A threaded plate is threadedly connected to the threaded rod. A movable plate is welded to the bottom surface of the threaded plate. The side of the insert post is slidably connected to the two movable plates.

[0006] Preferably, a rotating block is welded to the end face of the threaded rod, and a sealed bearing is interference-fitted to the side of the rotating block.

[0007] Preferably, the outer rings of the two sealed bearings are embedded and fixedly connected to the plug-in post, and a knob is welded to the top surface of the rotating rod.

[0008] Preferably, the bottom surface of the knob makes rotational frictional contact with the top surface of the support plate, and the clamping assembly includes a vertical plate and a clamping plate.

[0009] Preferably, the bottom surface of the vertical plate is welded to the support plate, and a fixing sleeve is embedded in the side of the vertical plate for fixed connection.

[0010] Preferably, a movable rod is inserted into the inner surface of the fixed sleeve, and a pull plate is welded to the end face of the movable rod.

[0011] Preferably, the top surface of the fixed sleeve is threaded with a fixing bolt, and the bottom surface of the threaded part of the fixing bolt abuts against the moving rod.

[0012] Preferably, the end of the moving rod away from the pull plate is welded to the clamping plate, and a rubber plate for extruding the mesh sand barrier is fixedly connected to the side of the clamping plate.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are:

[0014] This sand barrier connection and fixing device for sand control uses clamping components to clamp and fix the mesh-like sand barrier. Simultaneously, the insertion post and conical block extend into the sand body to secure the device. The conical block facilitates pushing the sand layer, and the insertion post extends into the sand body. Due to the low adhesion of the sand, the device is prone to tilting after the insertion post extends into the sand body, reducing its effectiveness in fixing the sand barrier. Rotating the knob drives the rotating rod, causing the active and driven bevel gears to mesh. With the connection of the connecting rod, the two threaded rods rotate, allowing the two threaded plates to move centrifugally along the threaded rods. This extends the two moving plates beyond the insertion post, increasing the vertical contact area between the device and the sand body, thus improving the device's effectiveness in fixing the sand barrier.

[0015] This sand barrier connection and fixing device for sand control and afforestation involves extending the insertion column into the sand body while the support plate is buried within it. By pulling the pull plate, the moving rod moves along the inner surface of the fixing sleeve, causing the clamping plate to move laterally. The clamping plate pushes the rubber plate, which, in conjunction with the vertical plate, clamps and fixes the mesh sand barrier. This allows for the installation and use of the mesh sand barrier, reducing wind speed and fixing the sand surface. The rubber plate provides cushioning protection, preventing damage to the sand barrier during clamping and fixing. The fixing bolt moves along the thread path of the fixing sleeve, thus abutting the moving rod and preventing the clamping plate from swaying or shifting, thereby improving the structural stability of the device components.

Detailed Implementation

[0024] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0026] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0027] To address the issue that sand barrier connection and fixing devices used for sand control are prone to instability when buried inside the sand, thus reducing their effectiveness in securing the sand barriers, please refer to [link to relevant documentation]. Figures 1 to 5 The structure of the device body includes a support plate 1 and a sand barrier clamping assembly 2 for sand prevention and control. The clamping assembly 2 is set on the top surface of the support plate 1. The support plate 1 supports the clamping assembly 2, and the clamping assembly 2 provides clamping and fixing function for the mesh sand barrier, realizing the initial support and fixing of the mesh sand barrier. The bottom surface of the support plate 1 is welded with a hollow insert post 3, and the top surface of the insert post 3 is welded with a conical block 4 for sand prevention and control. The conical block 4 and the insert post 3 are used to extend into the sand body. Since the sand body has low mutual adhesion, directly extending into the sand body through the insert post 3 and the conical block 4 results in a low installation and fixing effect of the device, and the device is very easy to tip over, reducing the installation and fixing effect of the device on the mesh sand barrier.

[0028] A fixing plate 5 is welded to the inner wall of the plug-in post 3. A rotating rod 6 is rotatably connected to the top surface of the fixing plate 5. A driving bevel gear is welded to the bottom surface of the rotating rod 6. The top surface of the driving bevel gear and the bottom surface of the fixing plate 5 are in rotational frictional contact. The driving bevel gear meshes with a driven bevel gear. The position of the driving bevel gear is fixed under the cooperation of the fixing plate 5 and the driven bevel gear, which enhances the meshing stability of the driving bevel gear and the driven bevel gear. A connecting rod 7 is fixedly connected to the side of the driven bevel gear, which makes the rotating rod 6 rotate. The rotation of the connecting rod 7 is realized during the transmission process. Two symmetrically arranged threaded rods 8 with reverse threads are welded to the end face of the connecting rod 7, which in turn realizes the rotation of the two threaded rods 8 with reverse threads. The threaded rods 8 are threadedly connected to a threaded plate 9, which makes the two threaded plates 9 move synchronously in opposite directions. A moving plate 10 is welded to the bottom surface of the threaded plate 9.

[0029] The side of the plug-in post 3 is slidably connected to the two movable plates 10. When the two threaded plates 9 move centrifugally, the two movable plates 10 extend out of the plug-in post 3, thereby increasing the vertical contact area between the movable plates 10 and the sand body. This allows the sand body to provide vertical fixation for the two movable plates 10, enhancing the installation and fixation stability of the device during transmission and preventing unstable support when the device extends into the sand body. This improves the installation and fixation effect of the device on the mesh sand barrier. The two movable plates 10 do not detach from the side wall of the plug-in post 3 during lateral movement, enhancing the lateral movement stability of the plug-in post 3.

[0030] A rotating block 11 is welded to the end face of the threaded rod 8. A sealed bearing 12 is interference-fitted to the side of the rotating block 11. The sealed bearing 12 fixes the rotation position of the rotating block 11, thereby fixing the rotation position of the threaded rod 8 and improving the structural stability of the device components. The outer rings of the two sealed bearings 12 are embedded and fixedly connected to the plug-in post 3. A knob 13 is welded to the top surface of the rotating rod 6. The bottom surface of the knob 13 makes rotational friction contact with the top surface of the support plate 1. By manually rotating the knob 13, the rotating rod 6 inside the plug-in post 3 can be rotated from the outside.

[0031] The clamping assembly 2 includes a vertical plate 14 and a clamping plate 19. The bottom surface of the vertical plate 14 is welded to the support plate 1. A fixing sleeve 15 is embedded and fixedly connected to the side of the vertical plate 14. One end of the fixing sleeve 15 located on the left side of the vertical plate 14 extends out of the vertical plate 14, and the other end of the fixing sleeve 15 located on the right side of the vertical plate 14 is flush with the vertical plate 14. A moving rod 16 is inserted into the inner tube surface of the fixing sleeve 15, so that the moving rod 16 moves along the inner tube surface of the fixing sleeve 15, thereby improving the lateral movement stability of the moving rod 16. A pull plate 17 is welded to the end face of the moving rod 16, and a fixing bolt 18 is threadedly connected to the top surface of the fixing sleeve 15.

[0032] The bottom surface of the threaded portion of the fixing bolt 18 abuts against the moving rod 16, causing the fixing bolt 18 to move along the threaded path of the fixing sleeve 15. Through the tight contact between the fixing bolt 18 and the moving rod 16, the position of the moving rod 16 is fixed, preventing the moving rod 16 from shaking or shifting. The end of the moving rod 16 away from the pull plate 17 is welded to the clamping plate 19. A rubber plate 20 for compressing the mesh sand barrier is fixedly connected to the side of the clamping plate 19. When the moving rod 16 moves along the inner tube surface of the fixing sleeve 15, it drives the clamping plate 19 to move. When the clamping plate 19 drives the rubber plate 20 to move towards the side of the vertical plate 14, the mesh sand barrier is clamped and fixed, fixing the position of the mesh sand barrier. The rubber plate 20 provides a buffer protection for the sand barrier, preventing the sand barrier from being damaged by clamping.

[0033] Working principle

[0034] When using this sand barrier connection and fixing device, the user manually pulls the pull plate 17 to move the moving rod 16 along the inner tube surface of the fixing sleeve 15, which in turn causes the clamping plate 19 to drive the rubber plate 20 to squeeze the mesh sand barrier, and causes the fixing bolt 18 to move along the thread path of the fixing sleeve 15, so that the fixing bolt 18 fixes the position of the moving rod 16.

[0035] The insertion post 3 and the conical block 4 extend into the sand body, the knob 13 is rotated, and the rotating rod 6 is rotated. Under the meshing action of the driving bevel gear and the driven bevel gear, the connecting rod 7 is rotated, and the connecting rod 7 synchronously drives the two threaded rods 8 with reverse threads to rotate, thereby realizing the reverse movement of the two threaded plates 9. The two moving plates 10 extend out of the insertion post 3 under the centrifugal movement of the two threaded plates 9, increasing the vertical contact area between the moving plates 10 and the sand body.
