Description

Technical Field

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

[0002] Water conservancy and hydropower projects refer to engineering projects constructed to eliminate water hazards and develop and utilize water resources. They are categorized by their service targets into flood control projects, farmland irrigation projects, hydropower projects, water supply and drainage projects, and environmental water conservancy projects. Water conservancy and hydropower projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways. The construction of these hydraulic structures requires a large amount of earthwork excavation, which creates slopes. During slope construction and at the slope base, the newly excavated soil layer is unstable or lacks support, making it easy for soil and rocks to detach from the slope. To ensure construction safety, slope protection devices are used to protect the slopes and ensure the safety of construction personnel and equipment.

[0003] Existing slope protection devices for water conservancy and hydropower projects are relatively simple in structure. They generally consist of galvanized square tubes welded into a rectangular frame, on which corrugated steel sheets or protective netting are installed. In use, the protection device is installed at the bottom of the slope, with the side facing away from the slope connected to the ground by a top pipe or steel reinforcement.

[0004] The existing slope protection devices for water conservancy and hydropower projects have the following problems during use: First, the protection devices are all separate and not connected to each other, resulting in poor overall integrity. Second, the protection devices face the slope directly, so when soil and rocks slide down the slope, they collide hard with the corrugated steel sheets or protective nets. The buffering effect of the corrugated steel sheets or protective nets is limited, and it is easy for the corrugated steel sheets or protective nets to be damaged or the protection devices to be knocked down, resulting in poor protection effect. Utility Model Content

[0005] To address the problems existing in the prior art, a slope protection device for water conservancy and hydropower engineering construction is provided. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0006] A slope protection device for water conservancy and hydropower projects includes:

[0007] The protective assembly consists of several protective panels connected sequentially. Each protective panel includes an upper support plate and a lower support plate. The lower end of the lower support plate is in contact with the ground. Several sets of buffer rollers are rotatably installed between the upper and lower support plates. The two ends of the roller shaft of each buffer roller pass through the upper and lower support plates, respectively, and are slidably connected to the upper and lower support plates. Both the upper and lower support plates are equipped with buffer devices that cooperate with the buffer rollers.

[0008] A connecting assembly is located between two adjacent protective panels. The connecting assembly cooperates with the two corresponding protective panels. The connecting assembly includes a sleeve, and threaded rods are threaded through and connected to both ends of the sleeve cavity. The other ends of the two threaded rods are respectively connected to the two protective panels.

[0009] Preferably, one end of the upper support plate is rotatably connected to an upper connecting plate, the upper connecting plate has a through hole, the other end of the upper support plate has a matching threaded hole, and fastening bolts are inserted into the corresponding threaded holes and through holes of two adjacent protective plates.

[0010] Preferably, one end of the lower support plate is rotatably connected to a lower connecting plate, one end of the lower connecting plate is fixedly connected to a pin, and the other end of the lower support plate is provided with a matching slot, with the pins of two adjacent protective plates passing through the corresponding slots.

[0011] Preferably, the lower support plate is provided with drainage holes that penetrate the lower support plate at intervals.

[0012] Preferably, both the upper support plate and the lower support plate are provided with grooves spaced apart, and the two ends of the roller shaft of the buffer roller pass through the grooves of the upper support plate and the lower support plate respectively, and the ends of the roller shaft slide in contact with the inner wall of the groove.

[0013] Preferably, the buffer device is disposed in the chute, the buffer device includes a slide rod, both ends of the slide rod are fixedly connected to the inner wall of the chute, the slide rod passes through the roller shaft, the slide rod is slidably connected to the roller shaft, and a buffer spring is sleeved on the slide rod on both sides of the roller shaft, the buffer spring is in slidable contact with the side wall of the slide rod, one end of the buffer spring is connected to the roller shaft, and the other end of the buffer spring is connected to the inner wall of the chute.

[0014] Preferably, the sidewall of the buffer roller is covered with an elastic layer, the material of which includes elastic rubber.

[0015] Preferably, the upper support plate and the lower support plate are respectively symmetrically fixedly connected to the side of the connecting assembly. The connecting block is provided with a socket. The end of the lead screw away from the sleeve is fixedly connected to a plug rod. The plug rod passes through the socket and slides in contact with the inner wall of the socket.

[0016] Preferably, a fastening hole penetrating the sleeve is provided on the side wall of the sleeve.

[0017] Preferably, two adjacent protective panels and their corresponding connecting components form a triangular structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model consists of a protective panel and connecting components. The protective panel is composed of multiple sets of protective single panels connected together. The lower end of the protective single panel is in contact with the ground. The connecting components are set between adjacent protective single panels and cooperate with the two protective single panels. The two adjacent protective single panels and the corresponding connecting components form a triangular structure. On the one hand, by connecting different numbers of protective single panels, the length of the protective panel can be adjusted to meet the construction protection needs of different lengths, thus having strong adaptability. On the other hand, the triangular structure formed by the two adjacent protective single panels and the corresponding connecting components has stability and better structural strength. When subjected to the impact of sand and gravel rolling down the slope, its impact resistance is stronger, thus providing better protection.

[0020] 2. In this utility model, buffer rollers are rotatably installed at intervals on the protective panel. The sidewalls of the buffer rollers are covered with an elastic layer. A buffer device is installed on the protective panel, which works in conjunction with the buffer rollers. During use, when sand and gravel rolling down the slope impact a buffer roller, the elastic layer on that buffer roller deforms, resulting in the first unloading of force. Simultaneously, under the impact, the buffer roller rotates, and under the action of the buffer device, the shaft end of the buffer roller slides along the length of the protective panel, resulting in the second unloading of force. Due to the angle between the protective panels, the sand and gravel slide down along the length of the protective panel, thus sequentially contacting the buffer rollers after the first one on the protective panel. Unloading occurs once after each buffer roller, thereby producing a step-by-step unloading effect, minimizing the impact force of the sand and gravel, and ensuring construction safety.

[0021] 3. In this utility model, an upper connecting plate is rotatably connected to one end of the upper support plate, and a through hole is provided on the upper connecting plate. A matching threaded hole is provided on the other end of the upper support plate. Fastening bolts are passed through the corresponding threaded holes and through holes of two adjacent protective panels. At the same time, a lower connecting plate is rotatably connected to one end of the lower support plate, and a pin is fixedly connected to one end of the lower connecting plate. A matching slot is provided on the other end of the lower support plate. The pins of two adjacent protective panels are passed through the corresponding slots. In use, the cooperation between the pin and the slot, as well as the cooperation between the threaded hole and the through hole, enables the quick connection and disassembly of the two protective panels, thereby shortening the assembly time of the protective panels and improving efficiency.

Detailed Implementation

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1 to 4 As shown, this utility model proposes a slope protection device for water conservancy and hydropower engineering construction, which includes:

[0033] The protective assembly is composed of several protective panels 100 connected in sequence. Each protective panel 100 includes an upper support plate 110 and a lower support plate 120. The lower end of the lower support plate 120 is in contact with the ground. Several sets of buffer rollers 101 are rotatably installed between the upper support plate 110 and the lower support plate 120. The two ends of the roller shaft of the buffer roller 101 are respectively inserted into the upper support plate 110 and the lower support plate 120. The two ends of the roller shaft of the buffer roller 101 are slidably connected to the upper support plate 110 and the lower support plate 120. Buffer devices are installed in both the upper support plate 110 and the lower support plate 120. The buffer devices cooperate with the buffer rollers 101.

[0034] The connecting assembly is located between two adjacent protective panels 100. The connecting assembly cooperates with the two corresponding protective panels 100. The connecting assembly includes a sleeve 200. Both ends of the sleeve 200 are threaded with screw rods 201. The other ends of the two screw rods 201 are respectively connected to the two protective panels 100.

[0035] In this embodiment, two adjacent protective panels 100 and their corresponding connecting components form a triangular structure. The sidewall of the buffer roller 101 is covered with an elastic layer, the material of which includes elastic rubber. There is a gap between the buffer rollers 101.

[0036] In addition, the inner wall of the sleeve 200 is threaded, and the thread is adapted to the lead screw 201. The two are located at the two ends of the sleeve 200 respectively, and the winding direction of the threads in the two lead screws 201 is opposite. So when the sleeve 200 is rotated, the two lead screws 201 can move closer to the middle or move further away from each other at the same time, thereby adjusting the length of the connecting assembly.

[0037] Before use, level and harden the ground at the bottom of the slope, and select an appropriate number of protective panels 100 according to the length of the slope.

[0038] Please refer to Figure 2 and Figure 3In use, the protective panels 100 are connected one after another to form a protective assembly. The lower end of the protective panel 100 is in contact with the ground. Adjacent protective panels 100 are reinforced with connecting components. The sleeve 200 is rotated to adjust the length of the connecting components so that the two adjacent protective panels 100 and the corresponding connecting components form a triangular structure, thus completing the connection between the protective panel 100 and the connecting components.

[0039] Of course, in order to increase the firmness of the connection between the protective panel and the ground, a relatively heavy material such as soil and rock can be abutted on the side of the protective panel 100 away from the slope, or iron pipes, steel bars and other diagonal bracing structures can be installed between the side of the protective panel 100 away from the slope and the ground. One end of the diagonal bracing is fixedly connected to the upper support plate 110, and the other end of the diagonal bracing is fixedly connected to the ground. The diagonal bracing plays a supporting and reinforcing role. These supporting and reinforcing measures are common reinforcement methods in the process of infrastructure construction, which are easy for those skilled in the art to think of. Additional measures can be added according to actual needs. This embodiment will not elaborate further.

[0040] During use, when soil and rocks roll down the slope, the soil and rocks that roll down the slope hit a buffer roller 101 on the protective panel 100. The elastic layer on the buffer roller 101 deforms, which is the first time to unload the force. Under the impact, the buffer roller 101 will rotate in the direction of soil and rocks rolling down. At the same time, with the cooperation of the buffer device, the roller shaft of the buffer roller 101 slides in the direction of soil and rocks rolling down, which together unloads the force for the second time.

[0041] Because there are angles between the protective panels 100 and between the protective panel 100 and the slope baseline, the soil and rocks will slide down along the length of the protective panel 100, and then sequentially contact the buffer rollers 101 after the buffer rollers 101 on the protective panel. Each time it passes through a buffer roller 101, it will unload the force as described above, thereby producing a step-by-step unloading effect, thus minimizing the impact force of the soil and rocks and ensuring construction safety.

[0042] In addition, two adjacent protective panels 100 and their corresponding connecting components form a triangular structure. Triangles are stable and have better structural strength. When subjected to the impact of soil and rocks rolling down the slope, they have stronger impact resistance. The cooperation between the protective panels 100 acts similarly to the four-cornered pyramid of a breakwater. The concave and convex curved surfaces formed between the protective panels 100 reduce the impact of rolling sand and gravel on the protective panels, thus improving the protective effect.

[0043] like Figures 1 to 6 As shown in one embodiment of the slope protection device for water conservancy and hydropower engineering of this utility model,

[0044] One end of the upper support plate 110 is rotatably connected to the upper connecting plate 111. The upper connecting plate 111 has a through hole 112. The other end of the upper support plate 110 has a matching threaded hole 113. Two adjacent protective plates 100 have fastening bolts passing through their corresponding threaded holes 113 and through holes 112.

[0045] The lower support plate 120 is rotatably connected to a lower connecting plate 121 at one end, and a pin 122 is fixedly connected to one end of the lower connecting plate 121. The other end of the lower support plate 120 is provided with a matching slot 123, and the pins 122 of two adjacent protective plates 100 are inserted into the corresponding slots 123.

[0046] Please refer to Figure 1 Connecting blocks 117 are symmetrically fixedly connected to the upper support plate 110 and the lower support plate 120 on the side near the connecting assembly. The connecting blocks 117 are provided with insertion holes 118. The end of the lead screw 201 away from the sleeve 200 is fixedly connected to the insertion rod 202. The insertion rod 202 passes through the insertion hole 118 and slides in contact with the inner wall of the insertion hole 118.

[0047] In this embodiment, the upper connecting plate 111 is rotatably disposed on the left end of the upper support plate 110, the threaded hole 113 is opened on the right end of the upper support plate 110, the lower connecting plate 121 is rotatably disposed on the left end of the lower support plate 120, and the slot 123 is opened on the right end of the lower support plate 120.

[0048] The upper support plate 110 and the lower support plate 120 are both provided with sliding grooves 114 at intervals. The two ends of the roller shaft of the buffer roller 101 are respectively inserted into the sliding grooves 114 of the upper support plate 110 and the lower support plate 120, and the ends of the roller shaft of the buffer roller 101 slide in contact with the inner wall of the sliding groove 114.

[0049] A buffer device is installed in the chute 114. The buffer device includes a slide rod 115. Both ends of the slide rod 115 are fixedly connected to the inner wall of the chute 114. The slide rod 115 passes through the roller shaft of the buffer roller 101 and is slidably connected to the roller shaft of the buffer roller 101. Buffer springs 116 are sleeved on the slide rods 115 on both sides of the roller shaft of the buffer roller 101. The buffer springs 116 are in slidable contact with the side walls of the slide rods 115. One end of the buffer spring 116 is connected to the roller shaft of the buffer roller 101, and the other end of the buffer spring 116 is connected to the inner wall of the chute 114.

[0050] In addition, the lower support plate 120 is provided with drainage holes 124 that penetrate the lower support plate 120 at intervals. By setting drainage holes 124, when water accumulates between the slope and the protective single plate 100, it can be quickly drained through the drainage holes 124 to avoid water accumulation and soaking the slope.

[0051] A fastening hole 203 is provided on the side wall of the sleeve 200, which is used to facilitate the worker to rotate the sleeve 200. The fastening hole 203 is located in the middle of the sleeve 200. When in use, the reinforcing bar is inserted into the fastening hole 203 to form a lever that saves effort. Rotating the reinforcing bar can rotate the sleeve 200, thereby changing the length of the connecting component.

[0052] Before use, the ground at the bottom of the slope should be leveled and hardened. When using, first insert the pin 122 of one of the two adjacent protective plates 100 into the slot 123 of the other protective plate 100. Then rotate the upper connecting plate 111 so that the through hole 112 is aligned with the threaded hole 113 of the other protective plate. Then connect the upper connecting plate 111 to the threaded hole 113 of the other protective plate with the fastening bolts.

[0053] It should be noted that the inner wall of the through hole 112 is smooth and without threads, so the upper connecting plate 111 can rotate relative to the fastening bolt and the upper connecting plate 111 respectively. At the same time, the pin 122 and the slot 123 can also rotate relative to each other, thereby changing the angle between two adjacent protective plates 100 to adapt to the support needs of different construction sites.

[0054] The engagement of the pin 122 with the slot 123 and the engagement of the through hole 112 and the threaded hole 113 of the upper connecting plate 111 enable the quick installation and disassembly of the protective single board 100, making it very convenient to use.

[0055] The insertion rods 202 at both ends of the connecting component are inserted into the sockets 118 and slide in contact with the inner wall of the sockets 118. Please refer to [reference needed]. Figure 3 In actual use, only one connecting block 117 on the upper support plate 110 of each protective panel 100 is in use, and only one connecting block 117 on the lower support plate 120 is in use.

[0056] Insert the reinforcing bar into the fastening hole 203 to form a lever that saves effort. Rotating the reinforcing bar will rotate the sleeve 200, thereby changing the length of the connecting component and completing the connection between the protective plate 100 and the connecting component.

[0057] In this embodiment, the protective panel 100 is connected to the connecting assembly on one side away from the slope.

[0058] In actual use, when soil and rocks roll down the slope, after the soil and rocks hit a buffer roller 101 on the protective panel 100, the elastic layer on the buffer roller 101 deforms, thus unloading the force for the first time. At the same time, under the impact, the shaft end of the buffer roller 101 slides along the slide bar 115, and the buffer springs 116 on both sides of the shaft end of the buffer roller 101 undergo elastic deformation. At this time, the buffer roller 101 will rotate in the direction of soil and rocks rolling down, thereby reducing the impact force of soil and rocks. Furthermore, the protective panel 100 is inclined to the slope, and the soil and rocks will slide down along the length of the protective panel 100, thus sequentially contacting the buffer roller 101 after the first buffer roller 101 on the protective panel. Each time it passes through a buffer roller 101, the force is unloaded as described above, thus producing a step-by-step unloading effect, thereby minimizing the impact force of soil and rocks and ensuring construction safety.

[0059] In addition, two adjacent protective panels 100 and their corresponding connecting components form a triangular structure. Triangles are stable and have better structural strength. When subjected to the impact of soil and rocks rolling down the slope, they have stronger impact resistance. The cooperation between the protective panels 100 acts similarly to the four-cornered pyramid of a breakwater. The concave and convex curved surfaces formed between the protective panels 100 reduce the impact of rolling sand and gravel on the protective panels, thus improving the protective effect.

[0060] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
