Description

Technical Field

[0001] The present invention relates to the technical field of river interception, and more particularly to a graded energy dissipation interception device for floating wood accumulation caused by rainfall and flood disasters. Background Art

[0002] During floods, rainfall and flooding in valleys cause landslides on both sides of the valley, trees fall and flow into the river, causing a large amount of floating wood to accumulate. It is necessary to set up an interception device in the river to intercept the floating wood. At present, most interception devices are too simple and do not have a graded interception function. They intercept all floating wood indiscriminately. If they are not cleaned in time, the excessive floating wood piles can easily block the river and cause damage to both sides of the river. In addition, some interception devices do not pay attention to the setting of energy dissipation mechanisms. Under the acceleration of the water flow, the floating wood can easily break through the interception device and flow downstream, causing damage to the downstream. Therefore, it is necessary to provide a graded energy dissipation interception device for floating wood accumulation caused by rainfall and flood disasters to solve the problems raised in the above background technology. Summary of the Invention

[0003] To achieve the above-mentioned object, the present invention provides the following technical solution: a hierarchical energy dissipation and interception device for floating wood accumulation caused by rainfall and flood disasters, comprising:

[0004] Two groups of fixed columns are symmetrically distributed and fixed on the inner sides of the riverbanks on both sides of the river channel, and the fixed columns are provided with moving parts;

[0005] The intercepting plate has a leaking hole structure in the middle, and its two sides can be rotatably arranged between the fixed columns, and a limit strip is provided on the upper part of the intercepting plate;

[0006] The rotating device is symmetrically distributed with two groups, fixed on both sides of the intercepting plate and fixedly connected to the moving part;

[0007] A plurality of buffer devices are distributed in a straight line and fixed on the top of the intercepting plate.

[0008] Furthermore, as a preference, the limit bar is a quarter of a cylinder, with the cut surface facing downward, and fixed to the top of the intercepting plate through adjacent cut surfaces. Driven by the movable part in the fixed column, the limit bar follows the intercepting plate for height adjustment. When the underwater distance of the bottom cut surface of the limit bar is less than one-third of the length of the underwater part of the driftwood, the driftwood hits the limit bar, thereby driving the rotating device to perform rotation buffering, and the driftwood is intercepted; when the underwater distance of the bottom cut surface of the limit bar is greater than two-thirds of the length of the underwater part of the driftwood, and less than the length of the underwater part of the driftwood, the driftwood hits the limit bar, thereby driving the rotating device to perform rotation buffering, and at the same time, the limit bar rotates with the intercepting plate, and then the position of the limit bar drops again, the driftwood breaks away from the limit bar, and after being buffered and energy-dissipated by the buffer device, it breaks away from the intercepting device of this level and enters the next intercepting device.

[0009] Furthermore, preferably, the rotating device includes:

[0010] The rotating shell is fixed on the moving part and follows the moving part to adjust the height;

[0011] The rotating disk is circular, with a pair of protrusions on the outer ring, the center of which is fixed to the side of the intercepting plate, and the outer part is rotatably connected to the rotating shell;

[0012] The limiting parts are provided with two pieces symmetrically distributed around the center and fixed in the rotating shell;

[0013] The compression spring has two sections and is fixed between the protrusion and the limit piece of the rotating disk. When the top of the intercepting plate is impacted by the floating wood, the intercepting plate deflects, thereby driving the rotating disk to rotate in the rotating shell, and then the outer ring protrusion of the rotating disk rotates toward the position of the limit piece, compressing the compression spring. At the same time, the compression spring itself rebounds and resets to offset the impact from the floating wood.

[0014] Furthermore, preferably, the buffer device includes:

[0015] a torsion spring, fixed to the top of the interceptor plate;

[0016] a fixing member, fixed in the intercepting plate, connecting adjacent torsion springs;

[0017] The buffer interception assembly is fixed to the middle part of the torsion spring. When the underwater distance of the bottom section of the limit bar is greater than two-thirds of the length of the underwater part of the driftwood and less than the length of the underwater part of the driftwood, or when the underwater distance of the bottom section of the limit bar is greater than the length of the underwater part of the driftwood, the driftwood will break away from the limit bar and hit the buffer interception assembly, thereby driving the buffer interception assembly to deflect, driving the torsion spring to deform, and performing buffering. Under the continuous action of the buffer interception assembly, after offsetting part of the impact force, the driftwood will break away from the interception device.

[0018] Furthermore, preferably, the buffer interception component includes:

[0019] The outer shell is fixed to the middle of the torsion spring, driving the torsion spring to deform and offset part of the impact force from the driftwood, and two symmetrically distributed tooth paths are provided inside the outer shell;

[0020] The adjustment plane is slidably arranged in the outer shell. When the torsion spring is deformed, the adjustment plane slides on the outer shell under the push of the driftwood, thereby sending the driftwood out.

[0021] The reset assembly connects the bottom of the adjustment plane and the lower inner wall of the external shell. When the adjustment plane is pushed by the driftwood to slide on the external shell, the reset assembly stretches. When the driftwood leaves the adjustment plane, the reset assembly contracts and resets, and at the same time drives the adjustment plane to reset.

[0022] Furthermore, preferably, the adjustment plane includes:

[0023] a sliding housing slidably disposed within the outer housing;

[0024] A plurality of adjusting rollers are arranged at intervals and fixed to the front surface of the sliding housing, with both ends passing through the side walls of the sliding housing and slidably connected to the inner wall of the outer housing;

[0025] There are multiple adjusting rollers, which are rotatably fixed on the adjusting roller;

[0026] The limiting nut passes through the side wall of the sliding housing and is rotatably arranged at both ends of the adjusting roller;

[0027] A transmission gear is provided on the inner side of the sliding housing and fixed on the limiting nut, wherein the limiting nut and the transmission gear are slidably connected, and the transmission gears on the same side of adjacent adjustment rollers are meshed with each other;

[0028] The moving gear is arranged on both sides of the bottom of the sliding shell and is fixedly connected to a group of transmission gears at the bottom. The moving gear is engaged with the tooth path. When the sliding shell slides on the external shell under the thrust of the driftwood, the moving gear rotates on the tooth path, thereby driving the transmission gear to rotate, driving the limit nut to move on the adjusting roller, and adjusting whether the adjusting roller rotates or not.

[0029] Furthermore, as a preference, the middle portion of the adjusting roller is fixed on the inner wall of the sliding shell, and threads corresponding to the limit nuts are provided at both ends, and the threads at both ends of the same adjusting roller have opposite rotation directions, and the threads on the same side of adjacent adjusting rollers have opposite rotation directions. In the initial state, the adjusting plane is in the external shell. At this time, restricted by the limit nut, the adjusting roller is in a fixed state on the adjusting roller. When the sliding shell is pushed on the external shell by the thrust of the driftwood, the moving gear drives the two coaxial transmission gears to rotate in the same direction, and then drives the adjacent transmission gears to rotate in the opposite direction. Then, under the action of the thread rotation direction on the adjusting roller, the limit nut moves to both sides at the same time, and then the adjusting roller is in a rotatable state. At this time, the driftwood slides over the adjusting roller, and then the buffer interception assembly is reset under the action of the torsion spring. Under the action of the reset assembly, the adjusting plane is reset, and then the moving gear drives the limit nut to move toward the middle through the transmission gear to lock the adjusting roller.

[0030] Furthermore, as a preference, the adjusting rollers are arranged between the limit nuts, and the diameter of the adjusting rollers is smaller than the spacing between the adjusting rollers, that is, there is a certain gap between each group of adjusting rollers, and each group of adjusting rollers can rotate automatically according to the contact position of the driftwood to buffer and send out the driftwood.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] In the present invention, through the setting of the rotating device, when the floating wood is intercepted, the compression spring inside the rotating device will be compressed with the impact of the floating wood and rebound at the same time. Under the continuous reaction force, the intercepted floating wood will gradually be kept in a stable state, which is convenient for collection and processing.

[0033] In the present invention, the buffer device is set up to mainly dissipate energy of floating wood. Through the cooperation of the buffer interception component and the rotating device, the smaller floating wood is intercepted and energy is dissipated, and then it is placed into the next-level interception device. For larger floating wood, with the cooperation of the limit bar and the rotating device, the impact force is gradually reduced and intercepted. The position of the limit bar can be adjusted by the movable part to specifically divide the interception interval of the floating wood. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] See also Figures 1 to 6 In an embodiment of the present invention, a hierarchical energy dissipation and interception device for floating wood accumulation caused by rainfall and flood disasters includes:

[0042] Two groups of fixed columns 1 are symmetrically distributed and fixed on the inner sides of the riverbank 2 on both sides of the river channel, and the fixed columns 1 are provided with moving parts 11;

[0043] The intercepting plate 3 has a leaking hole structure in the middle, and its two sides are rotatably arranged between the fixed columns 1, and a limiting strip 31 is provided on the upper part of the intercepting plate 3;

[0044] The rotating device 4 is symmetrically distributed with two groups, fixed on both sides of the intercepting plate 3, and fixedly connected to the moving member 11;

[0045] The buffer devices 5 are provided in plurality and distributed in a straight line and fixed on the top of the intercepting plate 3.

[0046] In this embodiment, the limit bar 31 is a quarter of a cylinder with a cross section facing downward and fixed to the top of the intercepting plate 3 through adjacent cross sections. Driven by the movable part 11 in the fixed column 1, the limit bar 31 follows the intercepting plate 3 for height adjustment. When the underwater distance of the bottom cross section of the limit bar 31 is less than one-third of the length of the underwater part of the driftwood, the driftwood hits the limit bar 31, thereby driving the rotating device 4 to perform rotation buffering, and the driftwood is intercepted; when the underwater distance of the bottom cross section of the limit bar 31 is greater than two-thirds of the length of the underwater part of the driftwood and less than the length of the underwater part of the driftwood, the driftwood hits the limit bar 31, thereby driving the rotating device 4 to perform rotation buffering, and at the same time, the limit bar 31 rotates with the intercepting plate 3, and then the position of the limit bar 31 drops again, the driftwood breaks away from the limit bar 31, and after being buffered and energy-dissipated by the buffer device 5, it breaks away from the intercepting device of this level and enters the next intercepting device.

[0047] In this embodiment, the rotating device 4 includes:

[0048] The rotating housing 41 is fixed on the moving member 11 and follows the moving member 11 to adjust the height;

[0049] The rotating disk 42 is circular, with a pair of protrusions on the outer ring, the center of which is fixed to the side of the intercepting plate 3, and the outer portion is rotatably connected to the rotating housing 41;

[0050] The limiting members 43 are provided with two symmetrically distributed parts around the center and fixed in the rotating housing 41;

[0051] The compression spring 44 has two sections and is fixed between the protrusion of the rotating disk 42 and the limit piece 43. When the top of the intercepting plate 3 is impacted by the floating wood, the intercepting plate 3 is deflected, thereby driving the rotating disk 42 to rotate in the rotating shell 41, and then the outer ring protrusion of the rotating disk 42 rotates toward the position of the limit piece 43, compressing the compression spring 44. At the same time, the compression spring 44 itself rebounds and resets to offset the impact from the floating wood.

[0052] In this embodiment, the buffer device 5 includes:

[0053] Torsion spring 51, fixed to the top of the interception plate 3;

[0054] A fixing member 52 is fixed in the interception plate 3 and connects adjacent torsion springs 51;

[0055] The buffer interception component 53 is fixed to the middle part of the torsion spring 51. When the underwater distance of the bottom section of the limit bar 31 is greater than two-thirds of the length of the underwater part of the driftwood and less than the length of the underwater part of the driftwood, or when the underwater distance of the bottom section of the limit bar 31 is greater than the length of the underwater part of the driftwood, the driftwood breaks away from the limit bar 31 and hits the buffer interception component 53, thereby driving the buffer interception component 53 to deflect, driving the torsion spring 51 to deform, and performing buffering. Under the continuous action of the buffer interception component 53, after offsetting part of the impact force, the driftwood breaks away from the interception device.

[0056] In this embodiment, the buffer interception component 53 includes:

[0057] The outer shell 531 is fixed to the middle of the torsion spring 51, driving the torsion spring 51 to deform and offset part of the impact force from the driftwood. Two symmetrically distributed tooth paths 5311 are provided inside the outer shell 531;

[0058] The adjustment plane 532 is slidably disposed in the outer shell 531. When the torsion spring 51 is deformed, the adjustment plane 532 is pushed by the driftwood and slides on the outer shell 531, thereby sending the driftwood out.

[0059] The reset assembly 533 connects the bottom of the adjustment plane 532 and the lower inner wall of the outer shell 531. When the adjustment plane 532 is pushed by the driftwood to slide on the outer shell 531, the reset assembly 533 is stretched. When the driftwood leaves the adjustment plane 532, the reset assembly 533 contracts and resets, while driving the adjustment plane 532 to reset.

[0060] In this embodiment, the adjustment plane 532 includes:

[0061] A sliding housing 5321 is slidably disposed within the outer housing 531;

[0062] Multiple adjustment rollers 5322 are provided at intervals and fixed to the front of the sliding housing 5321. Both ends of the adjustment rollers pass through the side walls of the sliding housing 5321 and are slidably connected to the inner wall of the outer housing 531.

[0063] There are multiple adjusting rollers 5323, which are rotatably fixed on the adjusting roller 5322;

[0064] The limiting nuts 5324 pass through the side wall of the sliding housing 5321 and are rotatably disposed at both ends of the adjusting roller 5322;

[0065] The transmission gear 5325 is disposed inside the sliding housing 5321 and fixed to the limiting nut 5324. The limiting nut 5324 and the transmission gear 5325 are slidably connected, and the transmission gears 5325 on the same side of adjacent adjustment rollers 5322 are meshed with each other.

[0066] The moving gear 5326 is arranged on both sides of the bottom of the sliding shell 5321 and is fixedly connected to a group of transmission gears 5325 at the bottom, and the moving gear 5326 is engaged with the tooth path 5311. When the sliding shell 5321 slides on the external shell 531 under the thrust of the floating wood, the moving gear 5326 rotates on the tooth path 5311, thereby driving the transmission gear 5325 to rotate, driving the limit nut 5324 to move on the adjusting roller 5323, and adjusting whether the adjusting roller 5323 rotates or not.

[0067] In this embodiment, the middle part of the adjusting roller 5322 is fixed on the inner wall of the sliding shell 5321, and threads corresponding to the limiting nuts 5324 are provided at both ends. The threads at both ends of the same adjusting roller 5322 rotate in opposite directions, and the threads on the same side of adjacent adjusting rollers 5322 rotate in opposite directions. In the initial state, the adjusting plane 532 is in the outer shell 531. At this time, it is restricted by the limiting nuts 5324, and the adjusting roller 5323 is in a fixed state on the adjusting roller 5322. When the sliding shell 5321 slides on the outer shell 531 under the thrust of the floating wood, the moving gear 5326 drives the two coaxial The transmission gears 5325 rotate in the same direction, thereby driving the adjacent transmission gears 5325 to rotate in the opposite direction. Then, under the action of the thread rotation direction on the adjusting roller 5322, the limit nut 5324 moves to both sides at the same time, and the adjusting roller 5323 is in a rotatable state. At this time, the floating wood slides over the adjusting roller 5323, and then the buffer interception component 53 is reset under the action of the torsion spring 51. Under the action of the reset component 533, the adjustment plane 532 is reset, and then the moving gear 5326 drives the limit nut 5324 to move to the middle through the transmission gear 5325, thereby locking the adjusting roller 5323.

[0068] In this embodiment, the adjusting rollers 5323 are arranged between the limiting nuts 5324, and the diameter of the adjusting rollers 5323 is smaller than the spacing between the adjusting rollers 5322, that is, there is a certain gap between each group of adjusting rollers 5323, and each group of adjusting rollers 5323 can rotate automatically according to the contact position of the driftwood, so as to buffer and send out the driftwood.

[0069] During specific implementation, first, multiple interception devices are set up in the river channel, and the height of the interception plate 3 is adjusted by the moving part 11. From upstream to downstream, the height of the interception plate 3 gradually increases, that is, the height of the limit bar 31 gradually increases. During interception, when the underwater distance of the bottom cross-section of the limit bar 31 is greater than the length of the underwater part of the driftwood, the driftwood slides over the top arc surface of the limit bar 31 and hits the buffer interception component 53, thereby driving the buffer interception component 53 to deflect, driving the torsion spring 51 to deform and perform buffering, thereby pushing the sliding shell 5321 to slide on the external shell 531, the reset component 533 is stretched, and the moving gear 5326 rotates on the tooth path 5311, thereby driving the transmission gear 5325 to rotate, driving the limit nut 5324 to move toward the two ends of the adjusting roller 5323, and then the adjusting roller 5323 is in a rotating state. At this time, the driftwood slides over the adjusting roller 5323 and enters the next interception device, and then the buffer interception component 53 is reset under the action of the torsion spring 51, and the adjustment plane 532 is reset under the action of the reset component 533; when the underwater distance of the bottom section of the limit bar 31 is greater than two-thirds of the length of the underwater part of the driftwood and less than the length of the underwater part of the driftwood, the driftwood hits the limit bar 31, thereby driving the rotating device 4 to rotate, and the interception plate 3 is deflected. As the interception plate 3 gradually deflects, the limit bar 31 gradually drops until the driftwood breaks away from the limit bar 31 and hits the buffer interception component 53, thereby driving the buffer interception component 53 to deflect, driving the torsion spring 51 to deform and perform buffering. Under the continuous action of the buffer interception component 53, after offsetting part of the impact force, it breaks away from the interception device and enters the next interception device; when the underwater distance of the bottom section of the limit bar 31 is less than one-third of the length of the underwater part of the driftwood, the driftwood hits the limit bar 31, thereby driving the rotating device 4 to rotate and buffer, and the driftwood is intercepted.
