Description

Technical Field

[0001] This utility model belongs to the field of agricultural protection facilities technology, specifically relating to a hail protection net support structure. Background Technology

[0002] Due to the frequent occurrence of disasters, the damage to crops is becoming increasingly severe. In order to prevent the damage to crops caused by natural disasters such as hail, hail protection nets are used to build isolation barriers, which effectively improves the protection of crops.

[0003] However, existing orchard hail protection nets mostly use cement pillars and steel pipes for construction. This structure is prone to collapse and is unstable in strong winds. Alternatively, they use steel pipes and cement pillars to form a separate support unit. This structure also suffers from poor stability due to its separate support system. In addition, the use of hinged structures leads to a short lifespan and safety hazards after long-term use, and there are also many inconveniences in later maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a hail protection net support structure. Based on the combined triangular structure, the independent support units are combined into a whole through structural design, which effectively improves the stability and durability of the hail protection net. At the same time, no professional personnel are required to come to the site, and users can perform maintenance and disassembly themselves.

[0005] To achieve the above objectives, this utility model provides a hail net support structure, including a support frame and a ground anchor fastening structure. The support frame includes a transverse tie rod and a plurality of central rods, and the central rods are arranged at equal intervals along the length direction of the transverse tie rod.

[0006] A connecting pipe is provided between two adjacent center rods;

[0007] A fixing block is pre-embedded at the bottom end of the central rod;

[0008] The ground anchor fastening structure includes a vertical rotating rod, on which a first connecting block and a second connecting block are provided. The first connecting block is located at the upper end of the second connecting block. The first connecting block is threadedly connected to the rotating rod, and the second connecting block is rotatably connected to the rotating rod.

[0009] It also includes an expansion anchor, the lower end of which is hinged to the second connecting block. A connecting rod is provided between the expansion anchor and the first connecting block, one end of which is hinged to the first connecting block and the other end of which is hinged to the expansion anchor.

[0010] The ground anchor fastening structure is connected to the support frame by a tension rope.

[0011] Furthermore, the connecting pipe is a V-shaped bend, and the two open ends of the connecting pipe are respectively fixedly connected to the adjacent central rod;

[0012] A connecting buckle is provided at the connection between the connecting pipe and the transverse tie rod.

[0013] Furthermore, the connecting buckle includes a front connecting buckle and a rear connecting buckle, the bottom of the front connecting buckle and the bottom of the rear connecting buckle are hinged together, and the top of the front connecting buckle and the top of the rear connecting buckle are connected by bolts.

[0014] The connecting buckle is provided with a lower limit hole that matches the horizontal tie rod, and an upper limit hole that matches the connecting tube is provided on the upper side of the lower limit hole.

[0015] Furthermore, the central rod and the transverse tie rod are fixedly connected by double U-shaped pipe clamps;

[0016] The left and right ends of the horizontal tie rod are equipped with corner tie rods and downward diagonal support rods;

[0017] One end of the corner tie rod is fixedly connected to the transverse tie rod, and the other end is fixedly connected to the top of the center rod and the connecting pipe;

[0018] One end of the lower inclined support is fixedly connected to the transverse tie rod, and the other end is fixedly connected to the central rod.

[0022] The hinge point between the connecting pipe and the expansion anchor is located at the upper end of the limiting groove;

[0023] The rotating rod has a collar at the top and a center at the bottom.

[0024] Compared with existing devices, this invention has the following advantages:

[0025] 1. Avoid excessive hinged and welded connections, and instead use clamps to directly connect each connecting pipe, effectively avoiding various abnormal noises and potential safety hazards to structural stability caused by long-term use;

[0026] 2. The traditional two diagonal bracing is replaced with a V-shaped bend pipe with integrated support, which combines the support units into a whole, greatly improving the stability and wind resistance of the structure.

[0027] 3. The structural design allows users to maintain or replace damaged parts themselves, reducing maintenance costs while ensuring the overall structural reliability.

[0042] Example 1

[0043] This embodiment provides, for example Figures 1 to 7 The hail protection net support structure shown includes a support frame 1 and a ground anchor fastening structure 7. The support frame 1 includes a transverse tie rod 3 and a plurality of central rods 2. The central rods 2 are arranged at equal intervals along the length direction of the transverse tie rod 3. The central rods 2 and the transverse tie rods 3 serve as the basic framework of the support frame 1. The transverse tie rods 3 and the central rods 2 are connected perpendicularly to each other to form a cross-shaped support structure.

[0044] A connecting pipe 4 is installed between two adjacent center rods 2, breaking the traditional single diagonal tie rod structure of the existing support device. The two adjacent center rods 2 are connected side by side through the connecting pipe 4, that is, the adjacent support units are combined into a whole in the horizontal direction, which greatly enhances the stability and wind resistance of the overall hail protection net.

[0045] A fixing block 21 is pre-embedded at the bottom of the center rod 2. The fixing block 21 is used to increase the weight at the bottom of the center rod 2 and is buried in the ground to connect with the ground, so as to ensure the vertical stability of the center rod 2.

[0046] The ground anchor fastening structure 7 includes a vertical rotating rod 71, on which a first connecting block 72 and a second connecting block 73 are provided. The first connecting block 72 is located at the upper end of the second connecting block 73. The first connecting block 72 is threadedly connected to the rotating rod 71, and the second connecting block 73 is rotatably connected to the rotating rod 71.

[0047] It also includes an expansion anchor 74, the lower end of which is hinged to the second connecting block 73. A connecting rod 75 is provided between the expansion anchor 74 and the first connecting block 72. One end of the connecting rod 75 is hinged to the first connecting block 72, and the other end is hinged to the expansion anchor 74.

[0048] The rotating rod 72 serves as the core driving structure of the ground anchor fastening structure 7, while the expansion anchor 74 is the expansion structure that realizes the expansion function. The ground anchor fastening structure 7 achieves the expansion action of the expansion anchor 74 by changing the relative distance between the first connecting block 72 and the second connecting block 73. Due to gravity, the first connecting block 72 will always hang downwards, while the second connecting block 73 moves up and down through the rotation of the rotating rod 72. Since the second connecting block 73 is threadedly connected to the rotating rod 72, the expansion anchor 74 will not fall off the first connecting block 72 when there is no relative rotation between the second connecting block 73 and the rotating rod 72, but will always maintain a connection with the spiral rod 72.

[0049] A connecting rod 75 is hinged between the expansion anchor 74 and the first connecting block 72. When the rotating rod 72 rotates and drives the first connecting block 72 to move downward, the upper end of the connecting rod 75 will move downward. Since the position of the first connecting block 72 remains unchanged, that is, the position of the lower end of the expansion anchor 74 remains unchanged, the lower end of the connecting rod 75 will press outward, thereby pushing the expansion anchor 74 outward, thus causing the upper end of the expansion anchor 74 to expand outward.

[0050] The ground anchor fastening structure 7 is connected to the support frame 1 by the tension rope 9, which provides a downward tension on the support frame 1 in the longitudinal direction, thereby increasing the structural stability of the support frame 1.

[0051] Furthermore, such as Figure 1 and Figure 2 As shown, the connecting pipe 4 is a V-shaped bend. The two open ends of the connecting pipe 4 are fixedly connected to the adjacent center rod 2 respectively, connecting the two adjacent center rods 2 to form an integral structure. That is, one end is connected to the center rod 2 on the left and the other end is connected to the center rod 2 on the right, thereby improving the overall structural integrity of the support frame 1 and its lateral anti-tipping ability.

[0052] A connecting buckle 8 is provided at the connection between the connecting pipe 4 and the horizontal tie rod 3. That is, at the lowest point of the connecting pipe 4, the connecting pipe 4 and the horizontal tie rod 3 are combined and installed by the connecting buckle 8. The connecting buckle 8 can quickly fix the connecting pipe 4 and the horizontal tie rod 3 together, avoiding structural damage to the pipe fittings that may be caused by welding, and also facilitating later maintenance and replacement of damaged pipe fittings.

[0053] Furthermore, such as Figure 3 As shown, the connecting buckle 8 includes a front connecting buckle 81 and a rear connecting buckle 82. The bottom of the front connecting buckle 81 and the bottom of the rear connecting buckle 82 are hinged together, and the top of the front connecting buckle 81 and the top of the rear connecting buckle 82 are connected by bolts. The hinge makes the front connecting buckle 81 and the rear connecting buckle 82 form an integral structure, which will not be separated and facilitates the assembly and fastening of the pipe fittings. The tops of the front connecting buckle 81 and the rear connecting buckle 82 are connected by bolts to complete the closure and fastening of the entire connecting buckle 8.

[0054] The connecting buckle 8 is provided with a lower limit hole 83 that matches the horizontal tie rod 3. The upper side of the lower limit hole 83 is provided with an upper limit hole 84 that matches the connecting tube 4. The horizontal tie rod 3 passes through the lower limit hole 83, and the center section of the connecting tube 4 passes through the upper limit hole 83. After the connecting tube 4 is placed on the horizontal tie rod 3, tightening the bolts on the connecting buckle 8 will complete the connection and fastening.

[0055] Furthermore, the center rod 2 and the transverse tie rod 3 are fixedly connected by double U-shaped pipe clamps. The double U-shaped pipe clamps are an existing pipe clamp structure that can quickly fix the cross structure. They are installed at the intersection of the center rod 2 and the transverse tie rod 3 and are quickly tightened by bolts.

[0056] Both ends of the horizontal tie rod 3 are equipped with corner tie rods 5 and lower diagonal support rods 6. One end of the corner tie rod 5 is fixedly connected to the horizontal tie rod 3, and the other end is fixedly connected to the top of the central rod 2 and the connecting pipe 4. The corner tie rod 5, together with the connecting pipe 4 and the central rod 2, forms an upper triangular diagonal brace structure to further reinforce the support frame 1.

[0057] One end of the lower inclined support rod 6 is fixedly connected to the transverse tie rod 3, and the other end is fixedly connected to the center rod 2. The lower inclined support rod 6 is installed at the lower end of the transverse tie rod 3, and together with the center rod 2 and the transverse tie rod 3, they form a lower triangular bracing structure.

[0058] Furthermore, such as Figure 4 As shown, the corner tie rod 5 and the lower inclined support rod 6 are fixedly connected to the transverse tie rod 3 and the central rod 2 by double plate clamps. The double plate clamps can quickly combine and install the head end of the round pipe fitting with the body of another round pipe fitting, which is convenient and reliable.

[0059] Furthermore, such as Figure 5As shown, the corner tie rod 5 is fixedly connected to the connecting pipe 4 and the center rod 2. The connection between the corner tie rod 5 and the connecting pipe 4 and the center rod 2 is located in a one-way open U-shaped buckle and is tightened with bolts.

[0060] Furthermore, such as Figure 6 and Figure 7 As shown, a limiting groove 76 is provided on the expansion anchor 74, and the protruding end of the second connecting block 73 is engaged with the lower end of the limiting groove 76. The expansion anchor 74 has a plate-shaped structure. The large plate-shaped area can greatly increase the contact area between the ground anchor fastening structure 7 and the ground. The limiting groove 76 is provided on the expansion anchor 74 to be hinged with the protruding end of the second connecting block 73.

[0061] The hinge of the connecting pipe 4 and the expansion anchor 74 is located at the upper end of the limiting groove 76. By pushing or pulling the upper end of the expansion anchor 74, the limiting groove 76 provides a hinge position for the expansion anchor 74.

[0062] The top of the rotating rod 71 is provided with a collar 77, which is used to tie the tension rope 9 to the support frame 1, providing additional structural reliability to the support frame 1. At the same time, a tip 78 is provided at the bottom, which can be pushed into the ground when the expansion anchor 74 is opened, to assist the expansion action of the expansion anchor 74.

[0063] In use: First, pour and install the fixing block 21 at the lower end of the central pole 2 and bury it in the ground to complete the installation and fastening of the central pole 2 to the ground. Then, install the horizontal tie rod 3 on the upper side of the central pole 2 through double U-shaped pipe clamps and fasten it with bolts to form the basic cross-shaped structure of the support pole 1. Compared with the traditional operation of adding a separate diagonal support rod, use an integrally formed V-shaped bend pipe, i.e., connecting pipe 4, and install it between two adjacent central poles 2. Then, add a lower diagonal support rod 6 and a corner tie rod 5 separately at the left and right ends of the entire support pole 1 to complete the triangular stability structure of the overall support pole 1, i.e., a horizontal row of support poles 1 in the support structure. Then, continue to install support poles 1 at equal intervals in the longitudinal direction until the entire support structure completely covers the orchard that needs to be protected. Finally, lay a hail protection net on the top of the support structure to complete the hail protection net laying process.

[0064] At the connection points of each pipe fitting, corresponding pipe clamps are used for connection and assembly. While ensuring the reliability of the connection structure, the convenience of installation and subsequent maintenance is optimized. The structural assembly of support frame 1 and the modification of some pipe fittings are completed. While reducing the maintenance difficulty for users, the independent support units are made into a unified whole, which can face more severe environmental problems.

[0065] After the support rod 1 is assembled, the position of the ground anchor fastening structure 7 is located. Then, a pit is dug and the ground anchor fastening structure 7 is buried underground. Before burying, the ground anchor fastening structure 7 can be placed on the ground with the tip 78 pressing against the ground. Then, by inserting a force-adding rod or other tool into the collar 77 and turning the rotating rod 71, the expansion action of the ground anchor fastening structure 7 can be completed. It should be noted that during operation, when the operator turns the rotating rod 71, he holds the first connecting block 72 for limiting assistance, so that the spiral rod 71 and the first connecting block 72 will rotate relative to each other. The arc-shaped expansion anchor 78 reduces the expansion resistance of the ground anchor fastening structure 7 while making the connection between the ground anchor fastening structure 7 and the ground tighter, further improving the stability of the support structure on the ground. During transportation, the expansion anchor 74 can be folded inward, i.e. Figure 7 The image shows the unopened state, which facilitates the transportation and storage of the ground anchor fastening structure 7.

[0066] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
