Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to slope protection devices for water conservancy and hydropower projects. Background Technology

[0002] In numerous fields such as civil engineering, road construction, and mining, slope protection is a crucial element in ensuring project safety and environmental stability. Due to the influence of various factors including geological conditions, climate, and human engineering activities, slopes are prone to geological disasters such as soil or rock collapses and landslides, posing a serious threat to surrounding buildings, infrastructure, and the lives of people. Therefore, effective slope protection technologies and equipment are of great significance for ensuring project safety and reducing disaster losses.

[0003] Currently, common slope protection technologies include rigid protection methods such as retaining walls, anchor bolts, and cable anchors, as well as flexible protective netting technology. While rigid protective structures can provide strong support to a certain extent, they suffer from problems such as complex construction, high cost, and poor adaptability to terrain. In complex terrain conditions, the construction difficulty increases significantly, requiring substantial manpower and material resources, and subsequent maintenance is also challenging. Existing flexible protective netting technology also has some shortcomings in practical applications. For example, traditional installation methods are cumbersome, typically requiring drilling holes in the slope and installing anchor bolts to fix the netting. This not only consumes a lot of time and manpower but may also cause further damage to the slope rock mass during drilling, affecting slope stability.

[0004] Furthermore, existing protective netting has limited stability after installation, especially under severe weather conditions such as strong winds and heavy rain, making it prone to loosening, displacement, or even detachment, thus failing to provide continuous and effective slope protection. The durability of the netting itself also needs improvement; long-term exposure to the natural environment makes it susceptible to rainwater erosion, ultraviolet radiation, and chemical corrosion, leading to decreased protective performance and a shortened lifespan. These problems severely restrict the quality and efficiency of slope protection projects, urgently requiring a new type of slope protection device to solve these issues and improve the reliability, convenience, and durability of slope protection. Utility Model Content

[0005] The purpose of this invention is to provide a slope protection device for water conservancy and hydropower projects, which solves the problem of insufficient stability of existing slope protection devices.

[0006] The technical solution adopted by this utility model is a slope protection device for water conservancy and hydropower projects, including a rectangular mounting frame, a protection mechanism is engaged inside the mounting frame, and a fixed column is vertically inserted at each of the four vertices of the mounting frame. The fixed column is hollow and has a pressure rod inside. A positioning cone is fixedly connected to the bottom of the fixed column. A sliding groove cavity is provided on the inner side of the fixed column near the positioning cone with the axis of the fixed column as the center. A pair of sliders are provided in the sliding groove cavity, and a fixing plate is fixedly connected to the sidewalls of the two sliders respectively.

[0007] The side wall of the fixed column has a pair of through sliding openings symmetrically opposite to the position of the sliding groove cavity. The pressure rod presses down and squeezes the slider, causing the pair of sliders to move in opposite directions, pushing the fixed plate out through the corresponding sliding opening;

[0008] The top of the fixed column is equipped with a locking mechanism, and the fixed column is connected to a sleeve through the locking mechanism.

[0009] The present invention is further characterized in that,

[0010] Insert blocks are fixedly connected to two adjacent side walls of the mounting bracket, and slots are provided on the other two side walls of the mounting bracket, with the slots matching the shape of the insert blocks.

[0011] The protective structure includes a protective net, and above the net, from bottom to top, are a corrosion-resistant layer, a waterproof layer, and a protective layer.

[0012] A nylon mesh is installed on top of the protective layer.

[0013] The sliding port is located below the mounting bracket.

[0014] The end of the pressure rod away from the fixed column is fixed with a downward pressure part, the diameter of which is larger than the diameter of the hollow hole in the fixed column.

[0015] The opposing surfaces of the two sliders are inclined planes that align with the cone direction of the positioning cone.

[0016] The locking mechanism is located above the mounting bracket. The locking mechanism includes a pair of round holes located on the side wall of the fixed column near the top. A spring is installed in the round hole. One end of the spring is located in the round hole and is fixedly connected to the fixed column. The other end is connected to a latch. The diameter of the latch is smaller than the diameter of the round hole.

[0017] There is a pair of limiting holes near the bottom of the sleeve, and the position of the limiting holes corresponds to the position of the locking buckle.

[0018] A pair of circular holes are symmetrically arranged along the axis of the fixed column.

[0019] A dust cover is fitted onto the outside of the latch.

[0020] The beneficial effects of this utility model are:

[0021] (1) The slope protection device for water conservancy and hydropower projects of this utility model has a sliding groove cavity at the bottom of the fixed column, and a pair of sliders connected to the fixed plate are set in the sliding groove cavity. When the pressure rod presses the slider downward, the slider is subjected to force and moves in the opposite direction, thereby causing the slider to drive the fixed plate to move outward of the fixed column, so that the fixed plate is inserted into the soil around the fixed column, forming a fixed position of the positioning cone. This improves the stability of the protection device when used on the slope. Even in the event of severe weather conditions such as strong winds and heavy rain, the radial fixation of the fixed column by the fixed plate prevents the device from being subjected to external force that could cause the fixed column to fall out of the soil, resulting in a positional shift and thus causing a safety accident.

[0022] (2) The slope protection device for water conservancy and hydropower projects of this utility model improves the protection effect of the protective net by stacking multiple layers on the surface of the protective net, avoids the protective net from rusting and corrosion caused by the harsh outdoor environment during use, thus preventing damage to the protective structure, improving the service life of the protective device and reducing the operating cost.

[0023] (3) The slope protection device for water conservancy and hydropower projects of this utility model has a sleeve on the outside of the fixed column, and the sleeve and the fixed column are fixed relative to each other by a locking mechanism. The locking mechanism uses the cooperation of spring and buckle to push the buckle into the limiting hole on the sleeve to form a good locking relationship. When it is necessary to unlock, just press the buckle protruding from the side wall of the sleeve to make the buckle disengage from the limiting hole, and then lift it up to realize the quick unlocking of the sleeve and the fixed column. The operation is very simple and quick. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] This utility model relates to a slope protection device for water conservancy and hydropower projects, such as... Figure 1 As shown, the mounting bracket 1 is rectangular and has a protective mechanism inside. Fixed posts 10 are vertically inserted at the four vertices of the mounting bracket 1. The fixed posts 10 are hollow tubes and have pressure rods 8 inside. The pressure rods 8 pass through the hollow holes inside the fixed posts 10. To prevent the pressure rods 8 from passing directly through the fixed posts 10 and to facilitate striking the pressure rods 8, a pressing part is fixed to the end of the pressure rods 8 away from the fixed posts 10. The diameter of the pressing part is larger than the diameter of the hollow holes in the fixed posts 10.

[0033] Furthermore, a positioning cone 6 is fixedly connected to the bottom of the fixed column 10. The top of the positioning cone 6 faces downward and is mainly used to break the soil so that the fixed column 10 can enter the slope body. A sliding groove cavity 11 is provided on the inner side of the fixed column 10 near the positioning cone 6 with the axis of the fixed column 10 as the center. A pair of sliders 12 are provided in the sliding groove cavity 11. The side walls of the two sliders 12 are respectively fixed with fixing plates 13.

[0034] Specifically, the hollow diameter of the slide cavity 11 is greater than the hollow hole diameter of the fixed column 10, and when the slider 12 abuts inside the slide cavity 11, the farthest distance between the two fixed plates 13 is less than the diameter of the fixed column 10.

[0035] Furthermore, a pair of through sliding openings 21 are symmetrically opened on the side wall of the fixed column 10 relative to the position of the sliding groove cavity 11. The pressure rod 8 presses down and squeezes the slider 12, causing the pair of sliders 12 to move in opposite directions, pushing the fixed plate 13 out through the corresponding sliding opening 21.

[0036] Furthermore, such as Figure 2As shown, a locking mechanism is provided at the top of the fixed column 10, and the fixed column 10 is connected to the sleeve 2 through the locking mechanism.

[0037] Example 2

[0038] The utility model of the slope protection device for water conservancy and hydropower projects includes a rectangular mounting frame 1, a protective mechanism is engaged inside the mounting frame 1, and a fixing column 10 is vertically inserted through the four vertices of the mounting frame 1. The fixing column 10 is hollow tubular and a pressure rod 8 is sleeved inside the fixing column 10.

[0039] A positioning cone 6 is fixedly connected to the bottom of the fixed column 10, with the top of the positioning cone 6 facing downwards, as shown. Figure 3 As shown, a sliding cavity 11 is provided on the inner side of the fixed column 10 near the positioning cone 6 with the axis of the fixed column 10 as the center. A pair of sliders 12 are provided in the sliding cavity 11, and fixed plates 13 are fixed to the side walls of the two sliders 12 respectively.

[0040] Furthermore, the opposing surfaces of the two sliders 12 are inclined surfaces that are aligned with the cone direction of the positioning cone 6.

[0041] Furthermore, a pair of through sliding openings 21 are symmetrically opened on the side wall of the fixed column 10 relative to the position of the sliding groove cavity 11, and the sliding openings 21 are located below the mounting bracket 1.

[0042] As the pressure rod 8 continues to move downwards until it contacts the two sliders 12 at the bottom of the fixed column 10, the pressure rod 8 applies an outward squeezing force to the two sliders 12 due to their unique shape design, forcing them to move outwards from the fixed column 10. During this process, the two sliders 12 are limited by the sliding groove cavity 11 and can only slide along the direction of the sliding groove cavity 11 at the bottom of the positioning cone 6. As the sliders 12 move outwards, the fixing plates 13 fixed on their opposite sides also move synchronously. When the sliders 12 slide to a certain position, the fixing plates 13 extend out of the fixed column 10 through the sliding opening 21 and are deeply inserted into the slope. In this way, a stable fixed support is provided for the mounting frame 1 in the horizontal direction, ensuring that the installation of the mounting frame 1 on the slope is more stable and reliable.

[0043] Example 3

[0044] Based on Embodiment 2, the mounting frame 1 of the water conservancy and hydropower engineering slope protection device of this utility model has two adjacent side walls with plugs 5 fixedly connected, and the other two side walls of the mounting frame 1 are provided with slots 4, the slots 4 and plugs 5 being adapted to each other.

[0045] The installation process begins with placing the mounting frame 1 in the designated installation area. Then, a hammering tool is used to strike the fixing posts 10 mounted on the mounting frame 1. This hammering action causes the tip of the positioning cone 6 to insert into the slope, initially establishing a connection between the mounting frame 1 and the slope.

[0046] Next, place the pressure bar 8 inside the fixing column 10, and then use a tool to tap the lower part of the pressure bar 8 again. Under the action of the tapping force, the pressure bar 8 will squeeze the slider 12, causing the fixing plate 13 to be pushed out from the sliding port 21 and inserted into the soil of the slope, thereby achieving the initial fixation of the mounting frame 1 on the slope.

[0047] When multiple protective nets need to be installed, the inserts 5 on the outer periphery of the mounting bracket 1 can be engaged with the slots 4 on another protective net mounting bracket. This engagement method allows multiple protective nets to be connected sequentially, achieving orderly installation and fixation, forming a continuous protective system.

[0048] Example 4

[0049] The utility model of the slope protection device for water conservancy and hydropower projects includes a cubic mounting frame 1, a protective mechanism is engaged inside the mounting frame 1, and a fixing column 10 is vertically inserted through the four vertices of the mounting frame 1. The fixing column 10 is hollow tubular and a pressure rod 8 is sleeved inside the fixing column 10.

[0050] A positioning cone 6 is fixedly connected to the bottom of the fixed column 10, with the top of the positioning cone 6 facing downwards, as shown. Figure 3 As shown, a sliding cavity 11 is provided on the inner side of the fixed column 10 near the positioning cone 6 with the axis of the fixed column 10 as the center. A pair of sliders 12 are provided in the sliding cavity 11, and fixed plates 13 are fixed to the side walls of the two sliders 12 respectively.

[0051] Furthermore, the side wall of the fixed column 10 has a pair of through sliding openings 21 symmetrically positioned relative to the sliding groove cavity 11. The pressure rod 8 presses down and squeezes the slider 12, causing the pair of sliders 12 to move in opposite directions, pushing the fixed plate 13 through the corresponding sliding opening 21.

[0052] A locking mechanism is provided at the top of the fixed column 10, and the fixed column 10 is connected to the sleeve 2 through the locking mechanism.

[0053] Furthermore, such as Figure 4 As shown, the locking mechanism is located above the mounting bracket 1. The locking mechanism includes a pair of round holes 14 located on the side wall of the fixing post 10 near the top. The pair of round holes 14 are symmetrically arranged along the axis of the fixing post 10.

[0054] A spring 15 is installed inside the round hole 14. One end of the spring 15 is located inside the round hole 14 and is fixedly connected to the fixing post 10. The other end is connected to a latch 16. A dust cover 9 is sleeved on the outside of the latch 16.

[0055] Furthermore, the diameter of the latch 16 is smaller than the diameter of the circular hole 14, and part of the latch 16 is located inside the circular hole 14;

[0056] A pair of limiting holes 7 are opened near the bottom of the sleeve 2, and the position of the limiting holes 7 corresponds to the position of the latch 16.

[0057] When it is necessary to put the sleeve 2 on the outside of the fixed post 10, the sleeve 2 is pushed down along the axis of the fixed post 10 until it is pressed against the locking buckle 16. Then, continue to press down. The locking buckle 16 moves into the round hole 14 under the downward pressure of the sleeve 2. When the limiting hole 7 of the sleeve 2 is aligned with the round hole 14, the locking buckle 16 pops out under the action of the spring 15, so that part of the locking buckle 16 enters the limiting hole 7, thus completing the relative position fixation of the sleeve 2 and the fixed post 10.

[0058] When it is necessary to disconnect the sleeve 2 and the fixed post 10, simply press the latch 16 and lift the sleeve 2 to unlock it.

[0059] Example 5

[0060] This utility model relates to a slope protection device for water conservancy and hydropower projects, comprising a cubic mounting frame 1, with a protective mechanism engaged inside the mounting frame 1, such as... Figure 5 As shown, the protective structure includes a protective net 20, and a corrosion-resistant layer 19, a waterproof layer 18, and a protective layer 17 are arranged sequentially from bottom to top on the protective net 20.

[0061] Furthermore, a nylon mesh 3 is provided above the protective layer 17.

[0062] Specifically, the waterproof layer 18 and corrosion-resistant layer 19 on the surface of the protective net 20 play crucial roles. The waterproof layer 18 effectively blocks the intrusion of rainwater, dew, and other moisture, preventing water from eroding and damaging the protective net 20. The corrosion-resistant layer 19 resists the corrosive effects of various chemicals from the external environment (such as acid rain and corrosive components in the soil), thereby significantly improving the service life of the protective net 20 and ensuring that the protective structure maintains good performance during long-term use, continuously and effectively protecting the slope.

[0063] Furthermore, the waterproof layer 18 is typically made of polyethylene. The corrosion-resistant layer 19 is typically made of hot-dip galvanized steel.

[0064] The working principle of this utility model is as follows: First, the mounting frame 1 is placed in the installation area. The fixing column 10 set on the mounting frame 1 is hammered by a punching tool, so that the tip of the positioning cone 6 is inserted into the slope until the fixing column 10 extends into the slope soil to a sufficient depth. Then, the pressure rod 8 is inserted into the fixing column 10. By striking the top side of the pressure rod 8 to contact the two sliders 12 at the bottom of the fixing column 10, the pressure rod 8 forces the two sliders 12 to move away from each other due to the shape of the sliders 12. The fixing plate 13 fixed on the side where the two sliders 12 are separated is inserted into the slope surface through the sliding opening 21 under the action of the sliders 12, thus achieving fixed support in the horizontal direction.

[0065] Example 6

[0066] Based on the above embodiments, the fixing plate 13 of the slope protection device for water conservancy and hydropower projects of this utility model gradually widens its vertical spacing from the end furthest from the slider 12 to the end closest to the slider 12, until it connects with the slider 12, similar to the axe head of an axe. This structure facilitates better insertion of the fixing plate 13 into the soil.

[0067] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0068] The above description of the disclosed embodiments enables those skilled in the art to make or use this application.
