Description
Technical Field
[0001] The invention belongs to the technical field of floating interception, and in particular relates to a floating interception body used for ultra-high-speed water flow. Background Art
[0002] The intercepting float is mainly composed of floats connected by steel wires or pins. The water flow speed that the intercepting float can adapt to mainly depends on the structural form of the intercepting float. The intercepting float of the traditional intercepting float is generally cylindrical or box-shaped, as shown in Figure 4. The resistance of the float facing the water surface is large, and the water level difference between the upstream and downstream of the float is large. Therefore, the traditional intercepting float can only be used for intercepting floating objects on the water with a water flow speed of 1-3m / s. The use of traditional intercepting floats under the condition of ultra-high-speed water flow speed>4m / s is easy to cause the float of the intercepting float to tip over and lose the interception function. What is more serious is that the traditional intercepting float cannot adapt to the vibration of the intercepting float caused by the ultra-high-speed water flow, and the intercepting float is very easy to be damaged and cause major accidents. In order to meet the needs of intercepting floating objects under ultra-high-speed water flow, there is an urgent need for an intercepting float that can still intercept floating objects under ultra-high-speed water flow, especially in areas such as hydropower stations, to effectively protect the power generation safety of the generator set and avoid the impact of damage to the generator set on economic construction and power safety. Summary of the invention
[0003] The purpose of the present invention is to provide a floating body for ultra-high-speed water flow to solve the problems of difficulty in intercepting floating objects on the water and easy overturning of the floating body under ultra-high-speed water flow conditions. To achieve the above purpose, the present invention provides the following technical solutions:
[0004] A floating body for intercepting ultra-high-speed water flow, comprising a floating body 1, a forward-tilted bow 2, a hanging fence 3 and a counterweight part 4; the forward-tilted bow 2 is arranged at the front end of the floating body 1; the counterweight part 4 is arranged at the rear end of the floating body 1; the hanging fence 3 is arranged at the bottom of the rear end of the forward-tilted bow 2; the front top of the forward-tilted bow 2 is provided with a front fixing part 6 for fixing a main rope 5; the top of the floating body 1 is provided with a rear fixing part 8 for fixing a secondary rope 7. It can be seen from the above structure that the forward-tilted bow 2 is arranged at the front end of the floating body 1, so the ultra-high-speed water flow impacts the forward-tilted bow 2. Since the front end top of the forward-tilted bow 2 is fixed to the main rope 5 through the front fixing part 6, when the forward-tilted bow 2 is subjected to a large impact, it will drive the floating body 1 to flip upstream with the main rope 5 as the rotation center; since the counterweight part 4 is provided at the rear end of the floating body 1, the lever arm of the center of gravity of the anti-floating body from the main rope 5 reaches the maximum, and the gravity moment generated can withstand the flipping moment generated by the impact of the water flow; in addition, since the top of the forward-tilted bow 1 is much higher than the top of the floating body 2, and the water-facing surface of the forward-tilted bow is at an angle of less than 90 degrees with the water surface, when the water-facing surface of the forward-tilted bow is subjected to the force of the water flow, the water flow will generate an upward force on the water-facing surface of the forward-tilted bow, which can cause the end of the anti-floating body to rise, so as to avoid the forward-tilted bow being submerged under the ultra-high-speed water flow, causing the anti-floating device to vibrate excessively and cause serious accidents. A hanging fence 3 is provided at the bottom of the rear end of the forward-tilted bow 2. Because the floating body 1 and the forward-tilted bow 2 will not completely leave the water surface as a whole under the gravity torque, the angle of the hanging fence 3 will not change much, and it can still play an effective role in intercepting floating objects. The top of the floating body 1 is fixed with a secondary rope 7 through the rear fixing part 8, and the secondary rope 7 also prevents the floating body 1 and the forward-tilted bow 2 from over-turning. The present invention solves the problem of difficulty in intercepting floating objects on the water under high water flow conditions; solves the problem that the intercepting floating body is easy to tip over and be damaged under high water flow conditions, causing the intercepting floating body to lose its interception function and possibly causing unforeseen accidents. Principle of anti-tipping of floating body: 1. Balance analysis of the floating body in the preset working state under low water flow velocity: establish the moment balance equation for the center point O of the hanging main rope 5 (the moment to keep the buoyancy box from turning over is positive), G*LGS-F*LFS-PS*hS=0, at this time, the impact force PS of the water flow on the floating body is small, and the water impact force tipping moment PS*hS is generally not large, the gravity balance moment G*LGS can be balanced with the tipping moment F*LFS and PS*hS, and can maintain the preset working state to work smoothly.2. Balance analysis of the floating body under ultra-high flow velocity: establish the moment balance equation for the center point O of the main suspension rope 5: G*LGf-F*LFf-Pf*hf=0. Under high flow velocity, the stabilizing force G does not change, the stabilizing arm LGf increases by about 1%, and the stabilizing moment increases by about 1.1%; the first tipping force - the impact force Pf of water on the floating body It has increased, but its tipping arm hf is much smaller than hS. When the floating body tilts to a certain angle, the tipping moment hf will be very small, close to zero, that is, the tipping moment of the floating body caused by the water impact force will eventually become very small; the second tipping force - the buoyancy of water always remains unchanged, but its lever LFf will be greatly reduced, that is, the buoyancy tipping moment will be greatly reduced; and the stabilizing force floating body's own weight G always remains unchanged, and its lever LGf will increase by about, that is, the gravity balance moment is about increased, and the gravity and buoyancy are equal. Therefore, the gravity balance moment G*LGf can completely balance the water impact tipping moment Pf*hf and the buoyancy tipping moment LFf, so that the floating body will never flip over.
[0005] Furthermore, the number of the front fixing parts 6 and the rear fixing parts 8 are both two, and the main rope 5 between the two front fixing parts 6 and the auxiliary rope 7 between the two rear fixing parts 8 are both perpendicular to the direction of the water flow from front to back. From the above structure, it can be seen that the main rope 5 between the two front fixing parts 6 and the auxiliary rope 7 between the two rear fixing parts 8 are parallel and perpendicular to the direction of the water flow from front to back, so the floating body 1 and the forward bow 2 cannot swing left and right, and when multiple floating bodies are strung together, they will not collide with each other, ensuring the integrity of the device.
[0006] Furthermore, both ends of the main rope 5 and the auxiliary rope 7 are connected to the hinge seat 9; the hinge seat 9 is connected to the fixed pier 10 on the shore. From the above structure, it can be seen that the main rope 5 and the auxiliary rope 7 can be adjusted in tension and corresponding position through the hinge seat 9; the force generated by the floating body is finally shared by the fixed pier 10.
[0007] Furthermore, the floating body 1 extends from front to back; the tilted bow 2 extends from the lower rear to the upper front. As can be seen from the above structure, the floating body 1 extends from the lower rear to the upper front, ensuring that the gravity arm is large enough; the tilted bow 2 extends from the lower rear to the upper front, ensuring that the tilted bow 2 directly resists the water flow. Under calm water conditions, since the freeboard height of the water-facing surface of the tilted bow 2 is much greater than the height of the floating body, and the water-facing surface of the tilted bow 2 is at an angle of less than 90 degrees to the water surface, when the water-facing surface of the tilted bow 2 is subjected to the force of the water flow, the water flow will generate an upward force on the water-facing surface of the end of the floating body, which can cause the end of the buoy to rise, thereby avoiding the excessive vibration of the buoy caused by the water flow submerging the end under ultra-high flow rate, causing serious accidents.
[0008] Furthermore, the center of gravity of the floating body 1, the forward bow 2, the hanging fence 3 and the counterweight 4 as a whole is on the floating body 1. As can be seen from the above structure, the center of gravity is on the floating body 1, ensuring that the gravity arm is large enough to prevent the floating body 1 and the forward bow 2 from overturning.
[0009] Furthermore, the hanging fence 3 is arranged vertically downward. It can be seen from the above structure that when working under ultra-high flow velocity, the hanging fence 3 is arranged vertically downward, and the hanging fence 3 plays the role of preventing drift.
[0010] Furthermore, the floating body 1 and the forward-tilted bow 2 are in a "T" shape when viewed from above. As can be seen from the above structure, the "T" shape means that the forward-tilted bow 2 fully hits the water flow, and the floating body 1 lengthens the lever arm. Figure 1 The gravity moment generated by the floating body is G*LGS, which is much larger than Figure 4 G1*L2+F buoyancy*L1 in the structure, so the floating body does not capsize under ultra-high-speed water flow. The anti-capsulation ability of the floating body is much greater than that of the traditional single pontoon with hanging fence structure.
[0011] Furthermore, the left-right width of the forward-tilted bow 2 is greater than the floating body 1; the front-to-back length of the floating body 1 is greater than the forward-tilted bow 2. As can be seen from the above structure, the left-right width of the forward-tilted bow 2 is greater than the floating body 1, and a hanging fence 3 is provided at the bottom of the rear end of the forward-tilted bow 2 to ensure that the hanging fence 3 is long enough to intercept more comprehensively. The front-to-back length of the floating body 1 is greater than the forward-tilted bow 2 to ensure that the gravity arm is long enough.
[0012] Furthermore, the forward-tilted bow 2 can float on the water. As can be seen from the above structure, the forward-tilted bow 2 itself is also a floating body.
[0013] Furthermore, the interior of the floating body 1 and the forward bow 2 is hollow; the top of the floating body 1 and the forward bow 2 are both provided with an openable cover 11. As can be seen from the above structure, the cover 11 can be opened, and adding sand into the floating body 1 and the forward bow 2 can change the gravity size and distribution of the floating body 1 and the forward bow 2, so as to better adapt to the water flow conditions.
[0014] The beneficial effects of the present invention are:
[0015] The present invention discloses a floating body for ultra-high-speed water flow, comprising a floating body, a forward-tilted bow, a hanging fence and a counterweight; the forward-tilted bow is arranged at the front end of the floating body; the rear end of the floating body is provided with a counterweight; the rear end bottom of the forward-tilted bow is provided with a hanging fence; the front end top of the forward-tilted bow is provided with a front fixing part for fixing a main rope; the top of the floating body is provided with a rear fixing part for fixing a secondary rope. The floating body for ultra-high-speed water flow of the present invention can solve the problems of difficulty in intercepting floating objects on the water and easy overturning of the floating body under ultra-high-speed water flow conditions.

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.
[0023] Embodiment 1:
[0024] See attached Figures 1 to 4A floating body for blocking ultra-high-speed water flow, comprising a floating body 1, a forward-tilted bow 2, a hanging fence 3 and a counterweight 4; the forward-tilted bow 2 is arranged at the front end of the floating body 1; the counterweight 4 is arranged at the rear end of the floating body 1; the hanging fence 3 is arranged at the bottom of the rear end of the forward-tilted bow 2; the front top of the forward-tilted bow 2 is provided with a front fixing part 6 for fixing a main rope 5; the top of the floating body 1 is provided with a rear fixing part 8 for fixing a secondary rope 7. It can be seen from the above structure that the forward-tilted bow 2 is arranged at the front end of the floating body 1, so the ultra-high-speed water flow impacts the forward-tilted bow 2. Since the front end top of the forward-tilted bow 2 is fixed to the main rope 5 through the front fixing part 6, when the forward-tilted bow 2 is subjected to a large impact, it will drive the floating body 1 to flip upstream with the main rope 5 as the rotation center; since the counterweight part 4 is provided at the rear end of the floating body 1, the lever arm of the center of gravity of the anti-floating body from the main rope 5 reaches the maximum, and the gravity moment generated can withstand the flipping moment generated by the impact of the water flow; in addition, since the top of the forward-tilted bow 1 is much higher than the top of the floating body 2, and the water-facing surface of the forward-tilted bow is at an angle of less than 90 degrees with the water surface, when the water-facing surface of the forward-tilted bow is subjected to the force of the water flow, the water flow will generate an upward force on the water-facing surface of the forward-tilted bow, which can cause the end of the anti-floating body to rise, so as to avoid the forward-tilted bow being submerged under the ultra-high-speed water flow, causing the anti-floating device to vibrate excessively and cause serious accidents. A hanging fence 3 is provided at the bottom of the rear end of the forward-tilted bow 2. Because the floating body 1 and the forward-tilted bow 2 will not completely leave the water surface as a whole under the gravity torque, the angle of the hanging fence 3 will not change much, and it can still play an effective role in intercepting floating objects. The top of the floating body 1 is fixed with a secondary rope 7 through the rear fixing part 8, and the secondary rope 7 also prevents the floating body 1 and the forward-tilted bow 2 from over-turning. The present invention solves the problem of difficulty in intercepting floating objects on the water under high water flow conditions; solves the problem that the intercepting floating body is easy to tip over and be damaged under high water flow conditions, causing the intercepting floating body to lose its interception function and possibly causing unforeseen accidents. Principle of anti-tipping of floating body: 1. Balance analysis of the floating body in the preset working state under low water flow velocity: establish the torque balance equation for the center point O of the hanging main rope 5 (the torque to keep the buoyancy box from flipping is positive), G*LGS-F*LFS-PS*hS=0, at this time, the impact force PS of the water flow on the floating body is small, and the water impact force tipping torque PS*hS is generally not large, the gravity balance torque G*LGS can be balanced with the tipping torque F*LFS and PS*hS, and can maintain the preset working state to work smoothly.2. Balance analysis of the floating body under ultra-high flow velocity: establish the moment balance equation for the center point O of the main suspension rope 5: G*LGf-F*LFf-Pf*hf=0. Under high flow velocity, the stabilizing force G does not change, the stabilizing arm LGf increases by about 1%, and the stabilizing moment increases by about 1%. The first tipping force - the impact force Pf of water on the floating body increases, but its tipping arm hf is greatly reduced compared to hS. When the floating body tilts to a certain angle, the tipping moment hf will be very small, close to zero, that is, the water impact force The overturning moment on the floating body will eventually become very small; the second overturning force - the buoyancy of water always remains unchanged, but its lever arm LFf will be greatly reduced, that is, the buoyancy overturning moment will be greatly reduced; and the stabilizing force floating body's own weight G always remains unchanged, and its lever arm LGf will increase approximately, that is, the gravity balance moment will increase approximately, and the gravity and buoyancy are equal, so the gravity balance moment G*LGf can completely balance the water impact overturning moment Pf*hf and the buoyancy overturning moment LFf, so that the floating body will never flip over.
[0025] Embodiment 2:
[0026] See attached Figures 1 to 4A floating body for blocking ultra-high-speed water flow, comprising a floating body 1, a forward-tilted bow 2, a hanging fence 3 and a counterweight 4; the forward-tilted bow 2 is arranged at the front end of the floating body 1; the counterweight 4 is arranged at the rear end of the floating body 1; the hanging fence 3 is arranged at the bottom of the rear end of the forward-tilted bow 2; the front top of the forward-tilted bow 2 is provided with a front fixing part 6 for fixing a main rope 5; the top of the floating body 1 is provided with a rear fixing part 8 for fixing a secondary rope 7. It can be seen from the above structure that the forward-tilted bow 2 is arranged at the front end of the floating body 1, so the ultra-high-speed water flow impacts the forward-tilted bow 2. Since the front end top of the forward-tilted bow 2 is fixed to the main rope 5 through the front fixing part 6, when the forward-tilted bow 2 is subjected to a large impact, it will drive the floating body 1 to flip upstream with the main rope 5 as the rotation center; since the counterweight part 4 is provided at the rear end of the floating body 1, the lever arm of the center of gravity of the anti-floating body from the main rope 5 reaches the maximum, and the gravity moment generated can withstand the flipping moment generated by the impact of the water flow; in addition, since the top of the forward-tilted bow 1 is much higher than the top of the floating body 2, and the water-facing surface of the forward-tilted bow is at an angle of less than 90 degrees with the water surface, when the water-facing surface of the forward-tilted bow is subjected to the force of the water flow, the water flow will generate an upward force on the water-facing surface of the forward-tilted bow, which can cause the end of the anti-floating body to rise, so as to avoid the forward-tilted bow being submerged under the ultra-high-speed water flow, causing the anti-floating device to vibrate excessively and cause serious accidents. A hanging fence 3 is provided at the bottom of the rear end of the forward-tilted bow 2. Because the floating body 1 and the forward-tilted bow 2 will not completely leave the water surface as a whole under the gravity torque, the angle of the hanging fence 3 will not change much, and it can still play an effective role in intercepting floating objects. The top of the floating body 1 is fixed with a secondary rope 7 through the rear fixing part 8, and the secondary rope 7 also prevents the floating body 1 and the forward-tilted bow 2 from over-turning. The present invention solves the problem of difficulty in intercepting floating objects on the water under high water flow conditions; solves the problem that the intercepting floating body is easy to tip over and be damaged under high water flow conditions, causing the intercepting floating body to lose its interception function and possibly causing unforeseen accidents. Principle of anti-tipping of floating body: 1. Balance analysis of the floating body in the preset working state under low water flow velocity: establish the torque balance equation for the center point O of the hanging main rope 5 (the torque to keep the buoyancy box from flipping is positive), G*LGS-F*LFS-PS*hS=0, at this time, the impact force PS of the water flow on the floating body is small, and the water impact force tipping torque PS*hS is generally not large, the gravity balance torque G*LGS can be balanced with the tipping torque F*LFS and PS*hS, and can maintain the preset working state to work smoothly.2. Balance analysis of the floating body under ultra-high flow velocity: establish the moment balance equation for the center point O of the main suspension rope 5: G*LGf-F*LFf-Pf*hf=0. Under high flow velocity, the stabilizing force G does not change, the stabilizing arm LGf increases by about 1%, and the stabilizing moment increases by about 1%. The first tipping force - the impact force Pf of water on the floating body increases, but its tipping arm hf is greatly reduced compared to hS. When the floating body tilts to a certain angle, the tipping moment hf will be very small, close to zero, that is, the water impact force The overturning moment on the floating body will eventually become very small; the second overturning force - the buoyancy of water always remains unchanged, but its lever arm LFf will be greatly reduced, that is, the buoyancy overturning moment will be greatly reduced; and the stabilizing force floating body's own weight G always remains unchanged, and its lever arm LGf will increase approximately, that is, the gravity balance moment will increase approximately, and the gravity and buoyancy are equal, so the gravity balance moment G*LGf can completely balance the water impact overturning moment Pf*hf and the buoyancy overturning moment LFf, so that the floating body will never flip over.
[0027] There are two front fixing parts 6 and two rear fixing parts 8, and the main rope 5 between the two front fixing parts 6 and the auxiliary rope 7 between the two rear fixing parts 8 are both perpendicular to the direction of the water flow from front to back. From the above structure, it can be seen that the main rope 5 between the two front fixing parts 6 and the auxiliary rope 7 between the two rear fixing parts 8 are parallel and perpendicular to the direction of the water flow from front to back, so the floating body 1 and the forward bow 2 cannot swing left and right, and when multiple floating bodies are strung together, they will not collide with each other, ensuring the integrity of the device.
[0028] Embodiment three:

Balance analysis of the floating body under ultra-high flow velocity: establish the moment balance equation for the center point O of the main suspension rope 5: G*LGf-F*LFf-Pf*hf=0. Under high flow velocity, the stabilizing force G does not change, the stabilizing arm LGf increases by about 1%, and the stabilizing moment increases by about 1%.

[0030] There are two front fixing parts 6 and two rear fixing parts 8, and the main rope 5 between the two front fixing parts 6 and the auxiliary rope 7 between the two rear fixing parts 8 are both perpendicular to the direction of the water flow from front to back. From the above structure, it can be seen that the main rope 5 between the two front fixing parts 6 and the auxiliary rope 7 between the two rear fixing parts 8 are parallel and perpendicular to the direction of the water flow from front to back, so the floating body 1 and the forward bow 2 cannot swing left and right, and when multiple floating bodies are strung together, they will not collide with each other, ensuring the integrity of the device.
[0031] Both ends of the main rope 5 and the auxiliary rope 7 are connected to the hinge seat 9; the hinge seat 9 is connected to the fixed pier 10 on the shore. From the above structure, it can be seen that the main rope 5 and the auxiliary rope 7 can be adjusted in tension and corresponding position through the hinge seat 9; the force generated by the floating body is finally shared by the fixed pier 10.
[0032] The floating body 1 extends from front to back; the tilted bow 2 extends from the lower rear to the upper front. As can be seen from the above structure, the floating body 1 extends from the lower rear to the upper front, ensuring that the gravity arm is large enough; the tilted bow 2 extends from the lower rear to the upper front, ensuring that the tilted bow 2 directly resists the water flow.

As can be seen from the above structure, the center of gravity is on the floating body 1, ensuring that the gravity arm is large enough to prevent the floating body 1 and the forward bow 2 from overturning.
[0034] The hanging fence 3 is arranged vertically downward. It can be seen from the above structure that when working under ultra-high flow velocity, the hanging fence 3 is arranged vertically downward, and the hanging fence 3 plays the role of preventing drift.
[0035] The floating body 1 and the forward-tilted bow 2 are in a "T" shape when viewed from above. As can be seen from the above structure, the "T" shape means that the forward-tilted bow 2 fully hits the water flow, and the floating body 1 lengthens the lever arm. Figure 1 The gravity moment generated by the floating body is G*LGS, which is much larger than Figure 4 G1*L2+F buoyancy*L1 in the structure, so the floating body does not capsize under ultra-high-speed water flow. The anti-capsulation ability of the floating body is much greater than that of the traditional single pontoon with hanging fence structure.
[0036] The left-right width of the forward-tilted bow 2 is greater than that of the floating body 1; the front-to-back length of the floating body 1 is greater than that of the forward-tilted bow 2. As can be seen from the above structure, the left-right width of the forward-tilted bow 2 is greater than that of the floating body 1, and a hanging fence 3 is provided at the bottom of the rear end of the forward-tilted bow 2 to ensure that the hanging fence 3 is long enough to intercept more comprehensively. The front-to-back length of the floating body 1 is greater than that of the forward-tilted bow 2 to ensure that the gravity arm is long enough.
[0037] The forward-tilted bow 2 can float on the water surface. As can be seen from the above structure, the forward-tilted bow 2 itself is also a floating body.
[0038] The interior of the floating body 1 and the forward bow 2 is hollow; the top of the floating body 1 and the forward bow 2 are both provided with an openable cover 11. As can be seen from the above structure, the cover 11 can be opened, and adding sand into the floating body 1 and the forward bow 2 can change the gravity size and distribution of the floating body 1 and the forward bow 2, so as to better adapt to the water flow conditions.
[0039] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
