Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, specifically to a slope excavation and support device for water conservancy and hydropower engineering. Background Technology

[0002] Water conservancy and hydropower projects, also known as hydrological and hydropower projects, are projects that utilize natural resources such as floods, rivers, lakes, and groundwater, and use hydroelectric equipment and systems to regulate and utilize wind power and other water resources, comprehensively utilizing water energy to achieve functions such as power generation, diversion and scheduling, river channel modification, soil and water conservation, water pollution control, and waterway maintenance. When excavating the slopes of water conservancy and hydropower projects, it is necessary to support the slopes through support devices.

[0003] For example, a slope support device for water conservancy structures, authorized by announcement number CN217839897U, includes a first support rod installed at the edge of the slope; and a second support rod installed at the edge of the slope for supporting and protecting the slope. Although the above document facilitates the laying and installation of protective netting and makes it convenient to use, and by rotating the rotating column to drive the roller to rotate, the protective netting is wrapped around the outer wall of the roller, making it easy to store the protective netting inside the first support rod;

[0004] However, in the existing support devices, when two support rods and a protective net are installed in the working position for support, if the slope of the water conservancy and hydropower project is eroded by rainwater for a long time during the rainy season, stones on the slope of the water conservancy and hydropower project are prone to roll down and impact the protective net, accumulating on the protective net. Moreover, without support for the protective net, it may be damaged, reducing the service life of the support device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a slope excavation support device for water conservancy and hydropower projects. It solves the problem that during the use of existing support devices, the slopes of water conservancy and hydropower projects are easily eroded by rainwater over a long period of time, causing stones on the slopes to roll down and impact the protective netting, which may damage the protective netting and reduce the service life of the support device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slope excavation support device for water conservancy and hydropower projects, comprising two pillars, with a protective netting between them. Each pillar has a support mechanism on its exterior, consisting of two sets of mechanisms. Each support mechanism includes: a first horizontal block, fixedly connected to the top of the two pillars on their adjacent sides; a first vertical block, rotatably connected to the inner wall of the first horizontal block via a pin; a hollow column, fixedly connected to the bottom of the first vertical block; a sleeve, rotatably connected to the bottom of the hollow column via a bearing; and a screw, threadedly connected to the inner wall of the sleeve and extending into the hollow column.

The first upright block rotates under the drive of the hollow column, causing the second upright block to align with the second horizontal block. Then, under the drive of the sleeve, the screw moves the second upright block closer to the second horizontal block. Finally, the bolts are rotated to fix it to the second horizontal block. The assembly unit assembles the support device for easy transport.

[0007] Preferably, the assembly unit includes: a double-ended stud, both ends of which are rotatably connected to the inner wall of one of the support columns via bearings; a handle, fixedly connected to the top of the double-ended stud; two horizontal posts, both threadedly connected to the outer wall of the double-ended stud, and both ends slidably engaged with the inner wall of one of the support columns; a socket, located inside one of the support columns; and insertion rods, both fixedly connected to the sides of the two horizontal posts that are close to each other, and inserted into the inner wall of the socket; wherein, driven by the handle, the double-ended stud causes the horizontal posts to move the insertion rods away from the sockets, separating the two support columns.

[0008] Preferably, a protruding strip is fixedly connected to one side of the protective net, and a plug is fixedly connected to the side of the protruding strip away from the protective net. The plug is inserted into the inner wall of a support column, and the insertion hole is opened in the inner wall of the plug.

The turntable is fixedly connected to the inner wall of the other support column by bolts; the surface of the rotating roller is mounted on the other side of the protective net.

[0011] Preferably, a first mounting plate is fixedly connected to the bottom of each of the two pillars.

[0012] Preferably, the front of each of the two pillars is fixedly connected to a connecting plate by bolts, the connecting plate is rotatably connected to a column by a pin, and the bottom of the column is rotatably connected to a second mounting plate by a pin.

Detailed Implementation

[0023] 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.

[0024] During use, existing support devices are often used in water conservancy and hydropower projects where slopes are eroded by rainwater for extended periods. This can cause stones to roll down the slopes and impact the protective netting, potentially damaging it and reducing the lifespan of the support devices.

[0025] In view of this, the present invention provides a slope excavation support device for water conservancy and hydropower projects. Through the cooperation of hollow columns, first vertical blocks, first horizontal blocks, sleeves, handles, screws, sliders, connecting rods, second vertical blocks, and second horizontal blocks, the device provides support for the protective netting in the front and rear directions, improves the overall service life of the device, and solves the problem that in the use of existing support devices, the slopes of water conservancy and hydropower projects are easily eroded by rainwater over a long period of time, causing stones on the slopes to roll down and impact the protective netting, which may damage the protective netting and reduce the service life of the support device.

[0026] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0027] Example 1, by Figures 1 to 6It is understood that the slope excavation support device for the hydropower project in this case includes two support columns 1. A protective net 2 is installed between the two support columns 1. During the excavation of the hydropower project slope, the workers move the two support columns 1 and the protective net 2 to fix them to the hydropower project slope. Then, the two support columns 1 are fixed to the support position of the hydropower project slope. The protective net 2 supports the hydropower project slope. Support mechanisms 3 are installed on the outside of the two support columns 1. There are two sets of support mechanisms 3. The support mechanism 3 includes: a first horizontal block 33, which is fixedly connected to the top of the two support columns 1 on the side that are close to each other; a first vertical block 32, which is rotatably connected to the inner wall of the first horizontal block 33 through a pin; and a hollow column. 31 drives the first vertical block 32 to rotate in a circle around the pin on the first horizontal block 33. The hollow column 31 is fixedly connected to the bottom of the first vertical block 32. When supporting the slope of the water conservancy and hydropower project, the workers rotate the hollow columns 31 on the front and rear sides of the protective net 2 in sequence. The hollow column 31 drives the second vertical block 37 to move. After roughly aligning the second vertical block 37 with the second horizontal block 38, the sleeve 34 is rotatably connected to the bottom of the hollow column 31 through the bearing. The workers rotate the sleeve 34. The screw 35 is threadedly connected to the inner wall of the sleeve 34. The sleeve 34 drives the screw 35 to move and extends into the interior of the hollow column 31. The connecting rod 36 is fixedly connected to the bottom of the screw 35. The screw 35 drives the connecting rod 36 to move. The second upright block 37 is rotatably connected to the outer wall of the connecting rod 36 via a bearing. The screw 35 drives the second upright block 37 to move. The second horizontal block 38 is fixedly connected to the bottom of the two pillars 1 on the side closest to each other, and is also fixedly connected to the inner wall of the second upright block 37 via bolts. While the worker rotates the sleeve 34, the position of the second upright block 37 is adjusted. Finally, the second upright block 37 is moved to the position between the two second horizontal blocks 38, so that the threaded holes on the second upright block 37 and the second horizontal block 38 are aligned. After completion, the worker stops rotating the sleeve 34 and rotates the bolts on the second horizontal block 38 to fix the second upright block 37 and the second horizontal block 38 together. When both sets of support mechanisms 3 are fixed, the protective net 2... The front forms an X shape. After the slope support of the water conservancy and hydropower project is completed, the workers rotate the bolts on the second horizontal block 38 in the opposite direction to separate the second horizontal block 38 and the second vertical block 37. Then, they rotate the sleeve 34 in the opposite direction to return the screw 35 to its initial position. Finally, they return the hollow column 31 to its initial position. The assembly unit 39 is set inside a support column 1. The first vertical block 32 rotates under the drive of the hollow column 31, causing the second vertical block 37 to align with the second horizontal block 38. Then, the screw 35 moves the second vertical block 37 closer to the second horizontal block 38 under the drive of the sleeve 34. Finally, the bolts are rotated to fix it to the second horizontal block 38. The support device is assembled through the assembly unit 39, which facilitates transportation.

[0028] In the specific implementation process, it is worth noting that when excavating the slope of a water conservancy and hydropower project, workers move two support pillars 1 and the protective net 2, fixing them to the slope. Then, the two support pillars 1 are fixed to the slope support positions, and the protective net 2 supports the slope. During slope support, workers sequentially rotate the hollow columns 31 on both sides of the protective net 2. The hollow columns 31 drive the first vertical block 32 to rotate in a circle around the pin on the first horizontal block 33. This, in turn, moves the second vertical block 37. After roughly aligning the second vertical block 37 with the second horizontal block 38, workers rotate the sleeve 34. The sleeve 34 drives the screw 35 to move, which in turn drives the connecting rod 36 to move, and then the screw 35 moves the second vertical block 37. While rotating the sleeve 34, the operator adjusts the position of the second upright block 37, and finally moves the second upright block 37 to the position between the two second horizontal blocks 38, so that the threaded holes on the second upright block 37 and the second horizontal block 38 are aligned. After completion, the operator stops rotating the sleeve 34 and rotates the bolt on the second horizontal block 38 to fix the second upright block 37 and the second horizontal block 38 together. When both sets of support mechanisms 3 are fixed, an X shape is formed in front of the protective net 2. After the slope support of the water conservancy and hydropower project is completed, the operator rotates the bolt on the second horizontal block 38 in the opposite direction to separate the second horizontal block 38 and the second upright block 37. The operator rotates the sleeve 34 in the opposite direction to return the screw 35 to the initial position. Finally, the hollow column 31 returns to the initial position, thereby supporting the protective net 2 in the front and rear directions and improving the overall service life of the device.

[0029] Furthermore, the assembly unit 39 includes: a double-ended stud 391, both ends of which are rotatably connected to the inner wall of a support column 1 via bearings; a handle 392, fixedly connected to the top of the double-ended stud 391; when the worker moves the entire device, the worker first rotates the handle 392, causing the double-ended stud 391 to rotate; two horizontal columns 393, both threadedly connected to the outer wall of the double-ended stud 391; the double-ended stud 391 drives the horizontal columns 393 to move, and their ends are slidably engaged with the inner wall of a support column 1; the two horizontal columns 393 slide in the limiting groove on the inner wall of the right support column 1, limiting the horizontal columns 393; and an insertion hole 395. Inside a support column 1, two horizontal columns 393 drive the insertion rods 394 to move. The two insertion rods 394 leave the insertion holes 395. The workers separate the two support columns 1 and move them. The insertion rods 394 are fixedly connected to the side of the two horizontal columns 393 that are close to each other and are inserted into the inner wall of the insertion holes 395. After moving to the slope support position of the water conservancy and hydropower project, the workers turn the handle 392 in the opposite direction, thereby driving the insertion rods 394 to be reinserted into 395 and installing the two support columns 1 together. Among them, the double-headed stud 391, driven by the handle 392, causes the horizontal column 393 to drive the insertion rods 394 to move away from the insertion holes 395 and separate the two support columns 1.

[0030] In the specific implementation process, it is worth noting that when the staff moves the entire device, the staff first rotates the handle 392, which rotates the double-headed stud 391. The double-headed stud 391 drives the horizontal column 393 to move. The two horizontal columns 393 slide in the limiting groove on the inner wall of the right end support column 1, limiting the horizontal column 393. The two horizontal columns 393 drive the insertion rod 394 to move. The two insertion rods 394 leave the insertion hole 395. The staff separates the two support columns 1 and moves them. After moving them to the slope support position of the water conservancy and hydropower project, the staff rotates the handle 392 in the opposite direction, thereby driving the insertion rod 394 to re-insert into 395, installing the two support columns 1 together, realizing the assembly of the entire device, which is convenient for its movement.

[0031] Furthermore, a protruding strip 4 is fixedly connected to one side of the protective net 2. When reinstalling, the worker moves the protruding strip 4, and the protruding strip 4 drives the insert 5 to be re-inserted into the right end support 1. The side of the protruding strip 4 away from the protective net 2 is fixedly connected to the insert 5. The insert 5 is inserted into the inner wall of one support 1. When the insert rod 394 leaves the insertion hole 395, the insert 5 leaves the right end support 1, separating the two support 1s. The insertion hole 395 is opened in the inner wall of the insert 5.

[0032] In the specific implementation process, it is worth noting that when the insertion rod 394 leaves the insertion hole 395, the insertion block 5 leaves the right end support 1, separating the two supports 1. When reinstalling, the staff moves the protrusion 4, and the protrusion 4 drives the insertion block 5 to be reinserted into the right end support 1 to assemble the two supports 1.

[0033] Furthermore, a handle 341 is fixedly connected to the outer wall of the sleeve 34. When the operator rotates the sleeve 34, the operator rotates the handle 341, which drives the sleeve 34 to rotate, making it convenient for the operator to rotate the sleeve 34. A slider 351 is fixedly connected to the top of the screw 35. When the screw 35 moves, the screw 35 drives the slider 351 to move. The slider 351 slides and engages with the inner wall of the hollow column 31. The slider 351 slides in the groove on the inner wall of the hollow column 31, limiting the screw 35 and improving the overall performance of the support mechanism 3.

[0034] In the specific implementation process, it is worth noting that when the operator rotates the sleeve 34, the operator rotates the handle 341, and the handle 341 drives the sleeve 34 to rotate, which makes it convenient for the operator to rotate the sleeve 34. When the screw 35 moves, the screw 35 drives the slider 351 to move. The slider 351 slides in the groove on the inner wall of the hollow column 31, which limits the screw 35 and improves the overall use effect of the support mechanism 3.

[0035] Specifically, when the staff moves the entire device, they first turn the handle 392, which rotates the double-headed stud 391. The double-headed stud 391 drives the horizontal columns 393 to move. The two horizontal columns 393 slide in the limiting groove on the inner wall of the right end support 1. The two horizontal columns 393 drive the insertion rods 394 to move, and the two insertion rods 394 leave the insertion holes 395. The insertion block 5 leaves the right end support 1, separating the two support columns 1. The entire device is then moved to the location of the slope support in the water conservancy and hydropower project. After completion, the work... The operator rotates handle 392 in the opposite direction, causing the insertion rod 394 to re-insert into 395, thus installing the two support pillars 1 together. The two support pillars 1 are then fixed to the slope support position of the hydropower project. At this time, the operator rotates the hollow columns 31 on both sides of the protective net 2 in sequence. The hollow columns 31 cause the first vertical block 32 to rotate in a circle around the pin on the first horizontal block 33. The hollow columns 31 then cause the second vertical block 37 to move. After roughly aligning the second vertical block 37 with the second horizontal block 38, the operator rotates handle 341. Handle 341 drives sleeve 34 to rotate, sleeve 34 drives screw 35 to move, screw 35 drives slider 351 to move, slider 351 slides in the groove on the inner wall of hollow column 31, screw 35 drives connecting rod 36 to move, screw 35 drives second upright block 37 to move. While the operator rotates sleeve 34, the position of second upright block 37 is adjusted. Finally, the second upright block 37 is moved to the position between the two second horizontal blocks 38, so that the threaded holes on the second upright block 37 and the second horizontal block 38 are aligned. After completion, the operator stops rotating sleeve 34. The worker rotates the bolt on the second horizontal block 38 to fix the second vertical block 37 and the second horizontal block 38 together. After both sets of support mechanisms 3 are fixed, they form an X shape in front of the protective net 2 to support the slope of the water conservancy and hydropower project. After the slope of the water conservancy and hydropower project is supported, the worker rotates the bolt on the second horizontal block 38 in the opposite direction to separate the second horizontal block 38 and the second vertical block 37. The worker then rotates the sleeve 34 in the opposite direction to return the screw 35 to its initial position and finally returns the hollow column 31 to its initial position.

[0036] Example 2, by Figure 1 and 2It is known that the inner wall of another support column 1 is rotatably connected to a rotating roller 21 via a bearing. After the worker moves the entire device to the working position, the worker rotates the bolt on the turntable 22 to release the turntable 22 from its fixation. Then the worker moves the right support column 1, thereby moving the protective net 2. The protective net 2 drives the rotating roller 21 to rotate, thereby unwinding the protective net 2. After the movement is completed, the worker rotates the bolt on the turntable 22 again to fix the turntable 22. The top of the left support column 1 has several threaded holes, and the top of the rotating roller 21 is fixedly connected to the turntable 22. The turntable 22 is fixedly connected to the inner wall of the other support column 1 by bolts. The surface of the rotating roller 21 is installed on the other side of the protective net 2. After the slope support of the water conservancy and hydropower project is completed, the fixation of the turntable 22 is released again, and the worker rotates the turntable 22, thereby causing the rotating roller 21 to rotate and roll up the protective net 2, making it convenient to store the protective net 2.

[0037] In the specific implementation process, it is worth noting that after the staff moves the entire device to the working position, the staff rotates the bolts on the turntable 22 to release the turntable 22 from its fixed position. Then, the staff moves the right end support 1, which in turn moves the protective net 2. The protective net 2 drives the rotating roller 21 to rotate, thereby unwinding the protective net 2. After the movement is completed, the staff rotates the bolts on the turntable 22 again to fix the turntable 22. The top of the left end support 1 has several threaded holes. After the slope support of the water conservancy and hydropower project is completed, the fixation of the turntable 22 is released again. The staff rotates the turntable 22, which causes the rotating roller 21 to rotate and roll up the protective net 2, making it convenient to store the protective net 2.

[0038] Furthermore, the bottom of each of the two support columns 1 is fixedly connected to a first mounting plate 11. The surface of the first mounting plate 11 is provided with mounting holes. There are four mounting holes on each first mounting plate 11. After the workers have completed the slope protection, they fix the two support columns 1 through the mounting holes on the two first mounting plates 11. After the protection is completed, the first mounting plates 11 are released to fix the entire device.

[0039] In the specific implementation process, it is worth noting that the surface of the first mounting plate 11 is provided with mounting holes. There are four mounting holes on one first mounting plate 11. After the workers have completed the slope protection, they fix the two pillars 1 through the mounting holes on two first mounting plates 11. After the support is completed, the fixing of the first mounting plate 11 is released to fix the whole device.

[0040] Furthermore, the front of each of the two support columns 1 is fixedly connected to a connecting plate 12 by bolts. After the slope protection is supported, the workers rotate the bolts on the connecting plate 12 to fix the connecting plate 12 to the two support columns 1. The connecting plate 12 is rotatably connected to the column 13 by a pin. There are two mounting holes on a second mounting plate 14. Then, the workers fix the position of the column 13 through the mounting holes on the second mounting plate 14. The bottom of the column 13 is rotatably connected to the second mounting plate 14 by a pin. After the support is completed, the fixing of the second mounting plate 14 and the fixing of the connecting plate 12 are released, so as to support the entire device.

[0041] In the specific implementation process, it is worth noting that after the slope protection is supported, the workers rotate the bolts on the connecting plate 12 to fix the connecting plate 12 to the two pillars 1. The surface of the second mounting plate 14 is provided with mounting holes, and there are two mounting holes on each second mounting plate 14. Then, the workers fix the position of the pillar 13 through the mounting holes on the second mounting plate 14. After the support is completed, the fixing of the second mounting plate 14 and the fixing of the connecting plate 12 are released to achieve overall support of the device.

[0042] Specifically, after the staff moves the entire device to the working position, they rotate the bolts on the turntable 22 to release its fixation. Then, they move the right-end support column 1, which in turn moves the protective net 2. The protective net 2 drives the rotating roller 21 to rotate, thus unwinding the protective net 2. After the movement is complete, the staff rotates the bolts on the turntable 22 again to fix it in place. Then, the staff fixes the two support columns 1 through the mounting holes on the two first mounting plates 11. After that, the staff rotates the bolts on the connecting plate 12 to fix the connecting plate 12 to the two support columns 1. The staff fixes the position of the column 13 through the mounting holes on the second mounting plate 14. After the support is completed, the staff releases the fixation of the second mounting plate 14, the connecting plate 12, and the first mounting plate 11. The staff then releases the fixation of the turntable 22 again and rotates the turntable 22, causing the rotating roller 21 to rotate and rewind the protective net 2.
