Description
Technical Field
The invention relates to the field of pier safety protection, in particular to a mooring type anti-collision facility cable adjusting and balancing method under the condition of limited water depth.
Background
In recent years, inland river shipping development is rapid, the number and tonnage of ships are continuously increased, once the ships deviate from a channel and impact a bridge, impact energy is huge, a bridge is easily damaged, a ship sinks, and the requirement of preventing the bridge from colliding is more prominent. Various related data show that ship collision becomes one of the main reasons for bridge collapse on a channel, the problem of preventing ship collision of the bridge becomes a key factor for restricting safe traffic, and 8 million cross-navigable river bridges in China face similar threats at any time.
Set up anti-collision facility to striding navigation river bridge, can avoid boats and ships direct impact bridge structures, reduce the boats and ships striking energy that transmits to bridge structures to effectively reduce pier damage risk. Since various ship bridge collision accidents are frequently seen in recent years, the problem of ship bridge collision is highly emphasized by the transportation department, and anti-collision facilities are definitely required to be arranged for bridges with high ship collision risks.
The existing anti-collision facilities are mainly divided into two structural types of independent type and attached type. The attached anti-collision facility mainly comprises a rubber fender and an anti-collision buoyancy tank, wherein the rubber fender can only be used for preventing a ship from colliding a bridge with a lower grade, and the anti-collision buoyancy tank can be flexibly designed according to the anti-collision grade. Because the attached anti-collision facility is in contact with the bridge pier, although the energy dissipation can be carried out on the ship impact force, the attenuated ship impact force can still be transmitted to the bridge structure, so that a certain requirement is imposed on the self resistance of the bridge. In addition, under the condition of large water level amplitude of a mountain river, the section adaptability of attached anti-collision facilities such as anti-collision floating boxes is weak, the shapes of piers of modern bridges are various, from traditional circular sections, oval sections, to special-shaped variable sections and the like, the section forms of the piers are more and more complex, and challenges are brought to the adaptability of the anti-collision facilities, most of the existing anti-collision devices can only adapt to non-variable section piers or piers with small section variability, such as patents CN108842692A, CN112431120A, CN112921790A and the like, but when the water level amplitude is large, the anti-collision facilities cannot effectively prevent the special-shaped variable section beams.
The independent anti-collision facility is not in contact with the bridge structure and is independent of the arrangement of the bridge structure. The conventional independent anti-collision facility is characterized in that a plurality of rigid concrete pile foundations are arranged around a bridge structure fortification area, when a ship-bridge collision accident occurs, a pile (group) can intercept a ship impacting a pier, and impact energy of the ship is absorbed through self damage. The method has the advantages that the collision force of the ship does not act on the bridge structure, the bridge protection effect is good, but the method has large damage to the self structure and the ship, small anti-collision area, large civil engineering investment and long engineering period, anti-collision facilities are easy to damage quickly and are not easy to replace and maintain, and the method is not suitable for the environment with deep water depth. In the existing independent anti-collision facilities, a scheme of adopting a buoyancy tank as an anti-collision facility is also provided, for example, patent CN105064284B, which proposes a tension leg buoyancy tank type pier anti-collision protection device, wherein the buoyancy tank is arranged around a pier, and the bottom of the buoyancy tank is connected with a submarine anchoring mechanism through a plurality of tension legs. Thus, the impact action of the ship directly acts on the buoyancy tank and does not act on the pier. However, the buoyancy tank in the patent is fixed in the underwater anchoring mechanism through the tension legs, although the tension legs have certain flexibility compared with the pile foundation, the buoyancy tank is still a protection mode similar to a foundation pile in nature, the self structure and the ship are easily damaged during impact, the life of the buoyancy tank is short, and the equipment adjustability and the adaptability of the device are poor. In order to adapt to the water level amplitude, the length of a cable needs to be adjusted through a winch arranged on a buoyancy tank, and under the normal condition, the power supply of a special winch is difficult to realize in the river reach of a field bridge area, so that the application of the method is limited.
In addition, CN102926355B has disclosed a stand-alone regional anti-collision device adapted to large water level amplitude, which is composed of an anti-collision belt, buoys at two ends of the anti-collision belt, and a guide well, wherein the buoys are constrained by the guide well, and the anti-collision belt can be adapted to water level free lifting.
In order to solve the above problems, the applicant considered to design an anti-collision pontoon device, i.e. a pontoon arranged floating on the water surface and connected to the bottom of the river bed by a movably connected cable. Like this the flotation tank can reduce and receive the undulant restriction from top to bottom of water level, when detecting that the flotation tank suffers great striking, can realize the anticollision through the locking device who sets up with hawser locking. However, how to better avoid the influence of wind waves, water flows and water level fluctuation on the buoyancy tank, improve the stability of the buoyancy tank, enable the constraint relationship between the buoyancy tank and the mooring rope to be automatically adjusted according to the water level condition, reduce the influence of water depth limitation on the buoyancy tank and solve the problem to be further considered.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a method for adjusting and balancing mooring ropes of an anchoring type anti-collision facility under the condition of limited water depth, which can be adjusted in an adaptive manner to better keep a buoyancy tank stable, and further can reduce the influence of water depth limitation, has good anti-collision effect and can further reduce the influence of water level fluctuation limitation.
In order to solve the technical problems, the invention adopts the following technical scheme:
the method is characterized in that the lower end of a cable connected with a buoyancy tank is connected with an anchor on a riverbed below the buoyancy tank, the other end of the cable bypasses a fixed pulley on the buoyancy tank and a movable pulley capable of horizontally moving in the front-back direction and then is connected with a first counterweight driving block, and the movable pulley is connected with a second counterweight driving block through the cable and enables the first counterweight driving block and the second counterweight driving block to form stress balance on the movable pulley in the front-back horizontal direction.
Like this, through two counter weight drive blocks that set up along the flotation tank fore-and-aft direction, can adjust flotation tank stability better, receive wave or wind-force effect no matter when swinging forward or backward, all can have the counter weight drive block in a relative opposite direction to play the effect of stabilizing the flotation tank by relying on dead weight and inertia. Therefore, the buoyancy tank cannot be easily influenced by waves and wind power, the fluctuation displacement floats away, the overall stability of the device is better, and the pier protection effect can be better improved.
Furthermore, in the method, when the water depth is greater than a set value, the first counterweight driving block and the second counterweight driving block are both in a suspended state, and self-height adjustment of the first counterweight driving block is used for adapting to water level change; when the water depth is smaller than a set value, the first counterweight driving block is in a bottom sinking state, the second counterweight driving block is in a suspension state, and self-height adjustment of the second counterweight driving block is used for adapting to water level change.
Therefore, the constraint relation between the buoyancy tank and the mooring rope can be automatically adjusted according to the water level condition, the influence of the limitation of the water depth can be reduced, and the buoyancy tank can be restrained with the mooring rope under the limiting condition of shallow water depth.
Further, the method is realized by a self-adaptive anti-collision buoyancy tank device, the self-adaptive anti-collision buoyancy tank device comprises a buoyancy tank, a pulley system is arranged on the buoyancy tank, and the pulley system at least comprises a bearing fixed pulley and a first cable; the bearing fixed pulley is fixedly arranged on the buoyancy tank; one end of a first cable is fixed on the river bed below the buoyancy tank, and the other end of the first cable bypasses the bearing fixed pulley and is connected with a first counterweight driving block; the first counterweight driving block is suspended between the buoyancy tank and the river bed; the self-adaptive balance adjusting device comprises a floating box, a first counterweight driving block, a second counterweight driving block and a third counterweight driving block, wherein the first counterweight driving block is arranged on the upper portion of the floating box; one end of a first cable is connected with the first counterweight driving block after sequentially passing around the bearing fixed pulley, the movable pulley and the steering fixed pulley close to the bearing fixed pulley; and the movable pulley is fixedly connected with a second cable, and the second cable bypasses the steering fixed pulley far away from the bearing fixed pulley and then is connected with a second counterweight driving block in a downward suspension manner.
Therefore, when the buoyancy tank is impacted, the buoyancy tank moves and drives the first counterweight driving block and the attached water to move upwards to do work, flexible energy dissipation and collision avoidance are achieved, and the protection effect on equipment and ships can be improved. Meanwhile, when the water level changes and the wind wave impacts and fluctuates, the self-adaptive up-and-down adjustment of the first counterweight driving block and the second counterweight driving block can be realized, and the stability of the device can be better ensured.
Further, the lower end of the first cable is connected to an anchoring block, and the anchoring block is placed on a river bed below the buoyancy tank; the pulley system also comprises a locking mechanism, wherein the locking mechanism is arranged on the buoyancy tank, the first cable passes through the locking mechanism, and the locking mechanism is used for locking and fixing the first cable when the collision force of the buoyancy tank exceeds a preset value.
Like this, anchor block gravity is greater than the gravity of first counter weight drive block and second counter weight drive block, and anchor block relies on self weight to fix at the riverbed, and first counter weight drive block and second counter weight drive block suspend in the aquatic, and the flotation tank floats at the surface of water. Therefore, when the buoyancy tank is impacted by a small force, the first cable slides on the force bearing fixed pulley to drive the first counterweight driving block to be pulled upwards to do work, so that the kinetic energy of the impacted buoyancy tank is consumed, and movable collision avoidance is realized. When the flotation tank receives the striking dynamics great, locking mechanism is fixed with first hawser locking, and flotation tank and anchor block control convert fixed connection into, and the anchor block withstands the flotation tank through the hawser and bears the striking energy dissipation, realizes fixed anticollision. And because the anchor block is only laid on the riverbed and is not completely fixed, when the buoyancy tank is impacted by overlarge force, the buoyancy tank can drag the anchor block below, the anchor block and attached water are driven by the buoyancy tank to displace to do work, and the tank body deforms to consume the collision kinetic energy of the ship, so that movable collision avoidance is realized again. Thus, the self-adaptive adjustment of at least three anti-collision energy dissipation modes can be realized by the anti-collision device according to different collision forces, so that the device is more flexible and changeable in use, has the characteristics of flexibility and rigidity, and can better adapt to different collision forces. Meanwhile, the floating box in the structure is not a completely fixed setting mode in the ordinary state, dynamic matching and stable balance are realized by the aid of the anchoring blocks and the counterweight driving blocks through the fixed pulleys, under the natural condition, when the water level changes, the mooring rope is automatically retracted and extended through lifting of the counterweight driving blocks to adjust the floating state of the floating box, and under the action of water flow force, the water flow force is balanced through the horizontal component force of the mooring rope, so that the floating box is in a micro-drifting state. Therefore, when the balance weight driving block bears the wind wave influence, the water level change and other conditions, the balance weight driving block can automatically retract and release the mooring rope by means of self weight to realize height adjustment and form new stable balance so as to adapt to the wind wave fluctuation and the water level change influence. Therefore, the device can be better protected, the service life is prolonged, the stability of the use state is improved, and the function of the device is not influenced by the water level. Therefore, the scheme has the characteristics of micro displacement and self-driven lifting collision avoidance, so that the protection device can be better, the service life is prolonged, the stability of the use state is improved, and the function of the device is not influenced by the water level. In addition, the components such as the pulley, the cable, the locking mechanism and the like actually form a positioning and restraining unit, a single buoyancy tank can be provided with one positioning and restraining unit, a plurality of positioning and restraining units can be arranged on one buoyancy tank, and the positioning and restraining units can be flexibly arranged according to the situation of the buoyancy tank. When the floating box is specifically arranged, the maximum fluctuation offset distance of the floating box can be calculated through the length of the rope, the depth of water and the angle of the mooring rope, so that the distance from the position of the anchoring block to the pier is set, the floating box is restrained in an effective facility area, the specific calculation process is the prior art, and is not detailed here.
Further, the mass of the first counterweight driving block is larger than that of the second counterweight driving block, and the length of the second cable above the second counterweight driving block and in the vertical suspension section is smaller than that of the first cable above the first counterweight driving block and smaller than the historical shallowest water level height (of the device setting position).
This is because many river courses have the problem that the water level changes greatly in the dry season and the flood season, and the fluctuation height of the water level is larger than the water level depth in the dry season. In this case, the use of a single counterweight driving block can cause the counterweight driving block to sink due to too long cable in the dry period, and the water rise period can cause the cable to be short in length due to too high water level. Therefore, after the scheme is adopted, the first mooring rope can be set to be long enough to meet the use requirement of the water rising period, and the first counterweight driving block and the second counterweight driving block are both in a suspended state in the period of high water level, so that the first counterweight driving block has larger mass and can play a leading role in adjustment. Meanwhile, in the dry season, the first counterweight driving block can be enabled to be in a bottom contact state and lose the effect, and the second counterweight driving block is still in a suspension state and occupies a dominant position, so that the balance of the buoyancy tank can be still maintained by the aid of the second counterweight driving block, and the function of the device is continuously realized. Therefore, the device can better realize self-adaptive adjustment to meet the use requirements of different water levels. During specific implementation, the maximum fluctuation drift distance of the floating box can be calculated and determined according to two conditions of suspension and bottoming of the first counterweight driving block, so that the position of an anchoring point of the anchoring block is determined, the protection effect of the device is better ensured, the specific calculation process is the prior art, and details are not given here.
Further, the sliding block is arranged in a sliding groove which is horizontally arranged. Thus, it is possible to facilitate the sliding thereof more.
Furthermore, an installation bin is arranged in the middle of the upper portion of the floating box, the force bearing fixed pulley, the movable pulley and the steering fixed pulley are all installed in the installation bin, and an access hole is formed in the upper end of the installation bin. Thus, the equipment is protected and the maintenance is realized.
Furthermore, the locking mechanism comprises a ratchet wheel coaxially and fixedly arranged with the bearing fixed pulley and a pendulum bob arranged below the ratchet wheel, the upper end of the pendulum bob can be suspended on a fulcrum fixed on the buoyancy tank in a swinging mode through a pendulum bob handle, a clamping plate is fixedly connected to the upper end of the pendulum bob handle in an inclined mode and abuts against the ratchet wheel, and when the impact force of the buoyancy tank exceeds the inertia of the pendulum bob, the pendulum bob swings to enable the clamping plate at the upper end to rotate and fall into the ratchet of the ratchet wheel to be hung.
Therefore, when the buoyancy tank is in a static state, the ratchet wheel does not interfere with the clamping plate at the upper end of the pendulum bob, and the rolling of the bearing fixed pulley is not influenced. When the buoyancy tank is impacted too much, the pendulum bob has enough swinging angle, so that the clamping plate can rotate into the ratchet of the ratchet wheel and be hung, and the force-bearing fixed pulley can be locked. Adopt mechanical structure to realize locking like this, have and need not electrical control, simple structure is ingenious, and locking is reliable, and the unblock is convenient (the unblock only needs the counter rotation fixed pulley can let the pendulum fall and realize the unblock afterwards). And the self-weight of the pendulum bob can be arranged, so that the adjustment of the impact reaction force of the buoyancy tank can be conveniently realized. And the locking of the mooring rope is realized through the locking of the bearing fixed pulley, so that the mooring rope is not completely locked, and when the buoyancy tank is impacted to exceed a set value within a certain range, the bearing fixed pulley is locked and cannot rotate, so that the mooring rope is locked to realize the fixation. But when the buoyancy tank is impacted by a great force and exceeds a preset range, the mooring rope can also perform sliding friction on the bearing fixed pulley, and then the anchoring block is pulled at the lower end of the mooring rope to perform work and energy dissipation, and the first counterweight driving block can also be pulled upwards by means of the sliding friction of the mooring rope to perform work and energy dissipation together. Therefore, the energy dissipation and energy consumption effects of the device in the extreme state can be better improved, and the anti-collision effect is improved.
Further, the pendulum comprises a hanging basket and a plurality of balancing weights arranged on the hanging basket.
Like this, the aforesaid is realized receiving striking lock reaction force size's regulation to the flotation tank conveniently through the increase and decrease of counter weight drive block.
Furthermore, the pendulum is installed in a pendulum installation cavity below the bearing fixed pulley, and the upper end of the pendulum handle penetrates through an opening in the upper end of the pendulum installation cavity and is fixedly connected with the clamping plate.
Like this, not only can protect the pendulum better, can rely on the opening to realize spacing to pendulum swing angle moreover for the cardboard of pendulum and the ratchet of ratchet hang the back, avoid the cardboard atress to make the pendulum continue to rotate and lead to the unblock, so can realize dying to the lock of locking state. The force bearing fixed pulley can be unlocked only by reversely rotating afterwards.
Furthermore, a rope groove in a spiral winding state is arranged on the bearing fixed pulley, and the first cable is wound and connected in the rope groove for at least one circle.
Therefore, the friction force can be improved through the effect of the wrapping connection and the rope groove, and the locking effect of the bearing fixed pulley on the first cable is better improved.
Furthermore, the bearing fixed pulley comprises a cylindrical inner core horizontally arranged and a plurality of arc-shaped plates arranged outside the inner core in a surrounding mode, the inner core surface is provided with a buffer over the arc-shaped plates along the diameter direction of the section circle, the buffer is provided with a telescopic outward supporting handle, and the arc-shaped plates are fixed at the outer end of the supporting handle and have a certain distance with the inner core.
This is because, when the buoyancy tank is impacted and the force-bearing fixed pulley is locked, the first cable and the force-bearing fixed pulley can bear a very large impact force, which is easy to damage. Therefore above-mentioned structure can make when the load fixed pulley is locked, when first hawser is taut suddenly, first hawser makes it inwards compress tightly and realizes the buffering through compressing tightly the arc, has greatly alleviated the destruction effect of the sudden taut pulling force of first hawser and the sudden pressure that is compressed tightly of load fixed pulley, has guaranteed the reliability of device, stability and life well.
Further, the damper is a hydraulic damper. The hydraulic damper can act and buffer only when bearing large force, and can better adapt to the characteristics and the requirements.
Furthermore, a vertical strip-shaped hole is formed in the position, penetrating out of the position, where the first cable is connected with one end of the first counterweight driving block, of the buoyancy tank, the first cable penetrates out of the first strip-shaped hole, and a vertical conical hole is formed in the position, where the first cable is connected with one end of the anchoring block and penetrates out of the buoyancy tank, and the first cable penetrates out of the first conical hole.
Therefore, when the anti-collision device is arranged, the anti-collision device is influenced by water, waves, wind and the like and meets the requirement for realizing the function of the device, and the anchor block is usually arranged in the direction which is far away from the pier relative to the buoyancy tank, so that the structure is adapted and matched with the layout positions of all the components, the components are better helped to realize the position layout, and the mooring rope can be better protected.
Further, an anti-winding protective cylinder is arranged below the conical hole, and the first cable penetrates through the anti-winding protective cylinder downwards and then is connected to the anchoring block downwards.
Therefore, the first mooring rope and the anchoring block are connected at the position which is closer to the front of the channel, and after the anti-winding protective cylinder is arranged, the floating objects can be effectively prevented from being wound, and the normal function of the mooring rope is ensured.
Therefore, the invention has the advantage of being capable of self-adaptively adjusting to better keep the buoyancy tank stable, and further enables the buoyancy tank to have good anti-collision effect and to be better reduced from the limit influence of water level fluctuation.

The specific embodiment is as follows: the method is characterized in that the lower end of a cable connected with a buoyancy tank is connected with an anchor on a riverbed below the buoyancy tank, the other end of the cable bypasses a fixed pulley on the buoyancy tank and a movable pulley capable of horizontally moving in the front-back direction and then is connected with a first counterweight driving block, and the movable pulley is connected with a second counterweight driving block through the cable and enables the first counterweight driving block and the second counterweight driving block to form stress balance on the movable pulley in the front-back horizontal direction.
Like this, through two counter weight drive blocks that set up along the flotation tank fore-and-aft direction, can adjust flotation tank stability better, receive wave or wind-force effect no matter when swinging forward or backward, all can have the counter weight drive block in a relative opposite direction to play the effect of stabilizing the flotation tank by relying on dead weight and inertia. Therefore, the buoyancy tank cannot be easily influenced by waves and wind power, the fluctuation displacement floats away, the overall stability of the device is better, and the pier protection effect can be better improved.
In the method, when the water depth is greater than a set value, the first counterweight driving block and the second counterweight driving block are both in a suspended state, and self-height adjustment of the first counterweight driving block is used for adapting to water level change; when the water depth is smaller than a set value, the first counterweight driving block is in a bottom sinking state, the second counterweight driving block is in a suspension state, and self-height adjustment of the second counterweight driving block is used for adapting to water level change.
Therefore, the constraint relation between the buoyancy tank and the mooring rope can be automatically adjusted according to the water level condition, the influence of water depth limitation can be reduced, and the buoyancy tank can form constraint with the mooring rope under the condition of the limitation of shallow water depth.
Specifically, this embodiment is implemented by the adaptive anti-collision buoyancy tank device shown in fig. 1-5, which includes buoyancy tanks 1 spaced outside the pier, and a pulley system disposed on the buoyancy tanks 1, the pulley system at least includes a bearing fixed pulley 2 and a first cable 3; the bearing fixed pulley 2 is fixedly arranged on the buoyancy tank 1; one end of a first cable 3 at the other end is fixed on the riverbed below the buoyancy tank 1, and the other end is connected with a first counterweight driving block 5 after bypassing the bearing fixed pulley 2; the first counterweight driving block 5 is suspended between the pontoon 1 and the river bed.
Therefore, when the buoyancy tank is impacted, the buoyancy tank moves and drives the first counterweight driving block and the attached water to move upwards to do work, flexible energy dissipation and collision avoidance are achieved, and the protection effect on equipment and ships can be improved. Meanwhile, when the water level changes and the wind wave impacts and fluctuates, the stability of the device can be better ensured through the self-adaptive up-and-down adjustment of the first counterweight driving block.
Wherein, the lower end of the first cable 3 is fixedly connected with an anchoring block 4; the anchoring block 4 is placed on the riverbed below the buoyancy tank; the pulley system further comprises a locking mechanism; the locking mechanism is arranged on the buoyancy tank 1, the first cable 3 passes through the locking mechanism, and the locking mechanism is used for locking and fixing the first cable 3 when detecting that the impact force of the buoyancy tank exceeds a preset value.
Like this, anchor piece gravity is greater than the gravity of first counter weight drive block and second counter weight drive block, and anchor piece relies on self weight to fix at the riverbed, and first counter weight drive block and second counter weight drive block hang in the aquatic, and the flotation tank floats at the surface of water. Therefore, when the buoyancy tank is impacted by a small force, the first cable slides on the force bearing fixed pulley to drive the first counterweight driving block to be pulled upwards to do work, so that the kinetic energy of the impacted buoyancy tank is consumed, and movable collision avoidance is realized. When the flotation tank receives the striking dynamics great, locking mechanism is fixed with first hawser locking, and flotation tank and anchor block control convert fixed connection into, and the anchor block withstands the flotation tank through the hawser and bears the striking energy dissipation, realizes fixed anticollision. And because the anchor block is only laid on the riverbed and is not completely fixed, when the buoyancy tank is impacted by overlarge force, the buoyancy tank can drag the anchor block below, the anchor block and attached water are driven by the buoyancy tank to displace to do work, and the tank body deforms to consume the collision kinetic energy of the ship, so that movable collision avoidance is realized again. Thus, the self-adaptive adjustment of at least three anti-collision energy dissipation modes can be realized by the anti-collision device according to different collision forces, so that the device is more flexible and changeable in use, has the characteristics of flexibility and rigidity, and can better adapt to different collision forces. Meanwhile, the floating box in the structure is not a completely fixed setting mode in the ordinary state, dynamic matching and stable balance are realized by the aid of the anchoring blocks and the counterweight driving blocks through the fixed pulleys, under the natural condition, when the water level changes, the mooring rope is automatically retracted and extended through lifting of the counterweight driving blocks to adjust the floating state of the floating box, and under the action of water flow force, the water flow force is balanced through the horizontal component force of the mooring rope, so that the floating box is in a micro-drifting state. Therefore, when the balance weight driving block bears the wind wave influence, the water level change and other conditions, the balance weight driving block can automatically retract and release the mooring rope by means of self weight to realize height adjustment and form new stable balance so as to adapt to the wind wave fluctuation and the water level change influence. Therefore, the device can be better protected, the service life is prolonged, the stability of the use state is improved, and the function of the device is not influenced by the water level. Therefore, the scheme has the characteristics of micro displacement and self-driven lifting collision avoidance, so that the protection device can be better, the service life is prolonged, the stability of the use state is improved, and the function of the device is not influenced by the water level. In addition, the components such as the pulley, the cable, the locking mechanism and the like actually form a positioning and restraining unit, a single buoyancy tank can be provided with one positioning and restraining unit, a plurality of positioning and restraining units can be arranged on one buoyancy tank, and the positioning and restraining units can be flexibly arranged according to the situation of the buoyancy tank. When the floating box is specifically arranged, the maximum fluctuation offset distance of the floating box can be calculated through the length of the rope, the depth of water and the angle of the mooring rope, so that the distance from the position of the anchoring block to the pier is set, the floating box is restrained in an effective facility area, the specific calculation process is the prior art, and is not detailed here.
Wherein the pulley system further comprises a movable pulley 15, a second counterweight driving block 16 and two diverting fixed pulleys 17, the movable pulley 15 is arranged on a slide block 18, the slide block 18 can be horizontally arranged in the middle of the floating box in a sliding way along the front and back directions (the direction far away from the pier is forward, and the opposite direction is backward), the force bearing fixed pulley 2 and a steering fixed pulley 17 are positioned at one end of the sliding direction of the slide block 18, the other steering fixed pulley is positioned at the other end of the sliding direction of the slide block 18, the first cable 3 is connected out from the force bearing fixed pulley 2 and then bypasses the movable pulley 15, and is wound on a steering fixed pulley close to the force bearing fixed pulley in a U shape and then hangs a first counterweight driving block 5 downwards, and a second cable 19 is fixedly connected to the movable pulley 15, and the second cable 19 is wound around a steering fixed pulley far away from the force bearing fixed pulley and then is connected with a second counterweight driving block 16 in a downward suspension manner. The reference numbers in the figure are a buoyancy tank 1, a force bearing fixed pulley 2, a first cable 3, an anchoring block 4 and a first counterweight driving block 5.
Like this, through two counter weight drive blocks that set up along the flotation tank fore-and-aft direction, can adjust flotation tank stability better, receive wave or wind-force effect no matter when swinging forward or backward, all can have the counter weight drive block in a relative opposite direction to play the effect of stabilizing the flotation tank by relying on dead weight and inertia. Therefore, the buoyancy tank cannot be easily influenced by waves and wind power, the fluctuation displacement floats away, the overall stability of the device is better, and the pier protection effect can be better improved.
Wherein the mass of the first counterweight driving block 5 is larger than that of the second counterweight driving block 16, and the length of the second cable 19 above the second counterweight driving block 16 in the vertical suspension section is smaller than that of the first cable 3 above the first counterweight driving block 5 in the vertical suspension section and smaller than the historical lowest water level height (of the device setting position).
This is because many river courses have the problem that the water level changes greatly in the dry season and the flood season, and the fluctuation height of the water level is larger than the water level depth in the dry season. In this case, the use of a single counterweight driving block can cause the counterweight driving block to sink due to too long cable in the dry period, and the water rise period can cause the cable to be short in length due to too high water level. Therefore, after the scheme is adopted, the first cable can be set to be long enough to meet the use requirement of the water-rising period, and the first counterweight driving block and the second counterweight driving block are both in a suspended state in the period of high water level (see figure 1), and the first counterweight driving block has larger mass and can play a leading role in adjustment. Meanwhile, in the dry season (see fig. 5), the first counterweight driving block can be caused to touch the bottom and lose the function, and at the moment, the second counterweight driving block is still in a suspension state and occupies a dominant position, so that the balance of the buoyancy tank can be still maintained by the second counterweight driving block so as to continuously realize the function of the device. Therefore, the device can better realize self-adaptive adjustment to meet the use requirements of different water levels. During specific implementation, the maximum fluctuation drift distance of the floating box can be calculated and determined according to two conditions of suspension and bottoming of the first counterweight driving block, so that the position of an anchoring point of the anchoring block is determined, the protection effect of the device is better ensured, the specific calculation process is the prior art, and details are not given here.
