Description
Technical Field
The invention relates to the technical field of positioning of floating facilities on water, in particular to a floating device capable of self-adapting to water level lifting and plane constraint positioning.
Background
The water floating facilities are important carriers for developing and utilizing water resources, and common water floating facilities comprise large ocean platforms, water floating wharfs, inland river navigation marks, floating bridges, floating wharfs, floating amusement platforms and the like. Two problems need to be solved when the floating facility on water is installed: in the fluctuation change of the water level, the cable is automatically wound and unwound according to the change of the water level; under the influence of a plurality of factors such as wind, waves and flow, the water level is superposed, and how to realize self-stabilization and accurate positioning.
The large-scale ocean floating facilities mostly utilize an electric drive automatic control technology to realize the automatic adjustment of the cable reeling and unreeling of an ocean platform. The inland river important floating platform mostly utilizes an electric control winch technology to realize the cable reeling and unreeling adjustment of the inland river important floating platform. The inland river floating platform generally adopts the artificial adjustment of hawser length, realizes the regulation of receiving and releasing of inland river floating platform. Therefore, the existing water floating facilities cannot realize self-adaptive water level lifting and accurate positioning under the condition of not externally connecting an external power supply. The access of an external power supply and the installation of electromechanical equipment increase the complexity and cost of floating facilities on one hand, and on the other hand, the external power supply condition is not available in certain application occasions. Therefore, the method for searching the simple, convenient and efficient self-adaptive water level lifting and accurate constraint positioning of the water floating facility under the condition of not accessing an external power supply has great engineering significance.
In order to solve the problems, the applicant considers that a floating platform self-positioning method is designed, the lower ends of cables are anchored by respectively adopting a cable at the front side and the rear side of the floating platform along the water flow direction, the upper ends of the cables are jointly connected to a force application component with floating self-adjusting capacity on the floating platform, and the two cables are simultaneously tensioned by the force application component to realize the positioning of the floating platform. In the above scheme, the floating body has two ends limited by the cable, so that the floating body can not move in a normal state. When the floating body is impacted by water flow, the stress of the cable on one side facing the acting force direction is increased, the stress of the cable on the other side is reduced, the floating body is subjected to plane displacement, and the angle and the stress of the cable are also changed. Through the floating self-adjusting function of the force application component (adjusting the mass of the counterweight driving block in the floating body), the plane displacement of the floating body meets the displacement deviation of different engineering requirements, and therefore the precise positioning of the floating body is realized. Therefore, the influence of wind waves (wind, current and water flow in the same direction) can be well avoided, and the precise positioning of the floating platform is realized.
However, what structure is adopted in particular can better implement the method, and the method can be automatically adjusted to better adapt to the water level rising and falling changes, and the problem to be solved is 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 floating device capable of realizing accurate positioning of a floating platform and better adapting to the change of water level elevation and the positioning of plane constraint.
In order to solve the technical problems, the invention adopts the following technical scheme:
a floating type device capable of self-adapting to water level lifting and plane constraint positioning comprises a floating platform floating on the water surface and a self-positioning system of the floating platform, wherein the self-positioning system of the floating platform comprises a front end cable arranged at one end of the floating platform facing to the water flow direction and a rear end cable arranged at one end opposite to the water flow direction, the lower end of the front end cable is obliquely and forwardly anchored under the water, and the lower end of the rear end cable is obliquely and rearwardly anchored under the water, and is characterized in that the self-positioning system of the floating platform also comprises a drum member horizontally arranged along the water flow direction, the drum member is rotatably arranged on the floating platform, the front end of the drum member is provided with a front end cable winding section, the upper end of the front end cable is wound on the front end cable winding section, the rear end of the drum member is provided with a rear end cable winding section, the upper end of the rear end cable and the front end cable are wound on the rear end cable winding section in the same direction, and a lifting rope winding section is arranged in the middle of the drum member, a lifting rope is wound on the counterweight lifting rope winding section in the direction opposite to the front end cable rope, and a counterweight driving block is suspended below the lifting rope.
When the device is used, the pre-tensioning force is applied to the cables at the front end and the rear end by means of the gravity of the counterweight driving block and the torque conversion of the drum member, so that the cables are tensioned and balanced, and the floating platform is kept still. When the front end of the floating platform is impacted by water flow, the force of the cable at the front end is increased, and the moment and the direction generated by the counterweight driving block suspended at the other side of the rotary drum are unchanged, so that the overall moment at the cable side is unchanged. Therefore, the pre-tension of the cable at the other end is reduced due to the fact that the stress of the cable at the front end is increased, the moments at two sides of the rotary drum component are kept balanced continuously, the floating platform keeps horizontal displacement unchanged (only tiny displacement is carried out in the deformation range of the cable), and accurate plane positioning constraint under the water flow impact state is achieved. Meanwhile, when the water level rises and falls, the self-adaptive adjustment of the retraction and release of the mooring rope is realized through the rotation of the rotating drum member, the height of the counterweight driving block is changed but the moment is not changed when the rotating drum rotates, so the retraction and release lengths of the mooring rope at the front end and the rear end of the other side of the rotating drum member are correspondingly adjusted but the moment is still kept unchanged, and the draft of the floating platform is not changed. Therefore, the self-positioning system of the floating platform can be better ensured to be self-adaptively adjusted according to the water level change, and the balance of the tensioning stress system is kept unchanged in the adjusting process.
More specifically, in the daily operation of the floating facility on water, the forces applied to the floating body mainly include the self-gravity, buoyancy, water flow force, wind force, wave force and the like of the floating body. In the scheme, acting force is applied to the fore-aft cable by the counterweight driving block, and water flow force, wind force and wave force are counteracted through self-adaptive adjustment of the internal force of the cable. Meanwhile, because a high-strength cable (preferably with the same gravity and buoyancy) is selected, the cable is in a tensioning and straightening state in water, and the drifting displacement of the cable is mainly generated by elastic deformation caused by the change of the internal force of the cable, so that the plane constraint positioning of the floating body is realized. The principle of the cable-stayed bridge is similar to that of a stay cable of a cable-stayed bridge, the change of the load of the bridge mainly causes the change of the internal force of each cable, but the influence of the whole deformation of the bridge is small. Therefore, the acting force of the mooring rope is applied by the counterweight driving block connected with the mooring rope in the floating body, and the weight of the counterweight driving block is determined according to the designed water flow force, the size of the wind and wave force and the positioning precision of the required floating body. When the water level rises and falls, the cable is retracted and released through the movement of the transmission mechanism in the floating body and the counterweight driving block, so that the cable is always kept in a straightening state and the floating body is lifted along with the water level at a set reference position. The invention provides a self-adaptive water level lifting and plane constraint positioning method for an over-water floating facility, which adopts a self-balancing principle and utilizes a mechanical structure to realize self-coupling locking between two symmetrically arranged mooring ropes, thereby realizing self-adjustment and self-adaptation under different water levels and flow speed conditions.
Of course, as other possible embodiments, the counterweight driving block in the above-mentioned embodiment may be changed into a spring member with a lower end fixed on the floating platform, or the upper end of the front end cable and the upper end of the rear end cable may be directly connected to two ends of a spring member on the floating platform, but this structure is not highly stable in force balance, and it is difficult to achieve adaptive adjustment according to water level variation.
Furthermore, the lower surfaces of the floating platforms corresponding to the front end cable winding section and the rear end cable winding section are respectively provided with a fixed pulley, and the front end cable and the rear end cable are respectively wound around the corresponding fixed pulleys and then are upwards wound and connected with the rotary drum member.
Therefore, the oblique tension of the mooring rope is converted into vertical force through the direction change of the fixed pulley, and the condition that the stress of the rotary drum component is more balanced and stable is ensured.
Further, the fixed pulley is arranged on a fixed pulley seat capable of horizontally rotating.
Thus, the convenient cable can be opened to form a certain angle so as to better keep balance and stability.
Furthermore, a vertical soft sleeve is arranged between the fixed pulley and the drum component, and the front end cable and the rear end cable respectively penetrate through the corresponding soft sleeve and are connected with the drum component.
In this way, the cable can be better protected.
Furthermore, the front end cable winding section and the rear end cable winding section are arranged in an equal diameter mode, and the diameter of the front end cable winding section and the diameter of the rear end cable winding section are larger than the diameter of the counterweight lifting rope winding section.
Therefore, the proportional adjustment of the cable take-up and pay-off length and distance can be realized through the diameter proportional change of each section of the drum member, and the length of the lifting rope required by the counterweight driving block is reduced.
Furthermore, a pod is arranged on the floating platform, and the counterweight driving block is suspended in the pod.
Therefore, the balance weight driving block can not be impacted by water flow to influence the stress balance, and the maintenance is more convenient. Certainly, when implementing, also can suspend the counter weight drive block in the water body of floating platform below, but easily receive the impact of rivers like this and influence, and be unfavorable for the maintenance.
Further, the drum member is rotatably mounted on a support frame through a bearing, and the support frame is fixed on the floating platform.
Therefore, the structure is simple, and the installation is convenient.
Furthermore, the front end cable winding section and the rear end cable winding section are respectively provided with an axially sliding sleeve by means of splines, and the front end cable and the rear end cable are wound on the corresponding sliding sleeves.
Therefore, when the mooring rope is automatically retracted and released along with the water level change, the mooring rope and the contact side edge position of the rotary drum component are always positioned right above the fixed pulley through the axial sliding automatic adjustment of the sliding sleeve, the influence of the inclination of the mooring rope on stress balance is avoided, and the stability and the reliability of a balanced stress system are better ensured.
Furthermore, the floating platform self-positioning system is provided with two sets, the rotary drum components of the two sets of floating platform self-positioning systems are horizontally arranged in parallel at intervals, and front-end cables and rear-end cables of the two sets of floating platform self-positioning systems are respectively connected to the opposite sides or the opposite sides of the two rotary drum components.
Therefore, when the front end cable of the single set of floating platform self-positioning system is impacted by water flow, the front end cable and the rear end cable are stressed differently, the stress difference of the same-direction side surfaces in the front and rear directions of the rotary drum component can generate torque in the horizontal direction, the rotary drum is rotated, and the floating platform is rotated. Therefore, after the improvement, the torques generated by the two sets of floating platform self-positioning systems can be just counteracted mutually, and the stability of the floating platform is better ensured.
Furthermore, the lower ends of the front end cable and the rear end cable are respectively fixed on corresponding anchor ingots at the water bottom.
Therefore, the folding and unfolding are convenient to fix and control.
The self-adaptive floating device comprises a floating platform floating on the water surface, and is characterized by further comprising a self-adaptive floating platform positioning self-adjusting system, wherein the self-adaptive floating platform positioning self-adjusting system comprises two drum members horizontally arranged in parallel at intervals, the drum members are arranged along the water flow direction and rotatably arranged on the floating platform, the front end of each drum member is provided with a front end cable winding section and is wound with a front end cable, the rear end of each drum member is provided with a rear end cable winding section and is wound with a rear end cable, the lower end of each front end cable is obliquely anchored underwater forward and downward in the direction facing the water flow, and the lower end of each rear end cable is obliquely anchored underwater backward and downward in the direction departing from the water flow; the front end mooring rope and the rear end mooring rope of each of the two rotary drum components are connected to the side face, away from each other, of one side of each of the two rotary drum components in a winding mode, a driving bevel gear is installed in the middle of each of the two rotary drum components, the two driving bevel gears are meshed with two driven bevel gears installed on the same rotating shaft respectively, the rotating shaft is rotatably and horizontally installed on the floating platform and is vertically arranged between the two rotary drum components, a lifting rope is further wound on the rotating shaft, and a counterweight driving block is arranged below the lifting rope in a hanging mode.
Compared with the former scheme, the self-positioning floating body device can apply acting force to the front end cable and the rear end cable of the two drum components respectively to tension the front end cable and the rear end cable of the two drum components through torque conversion and transmission based on the similar principle. The displacement of the floating body meets the requirements of various engineering applications on the positioning precision of the floating body by setting the mass of the internal counterweight driving block. Meanwhile, when the water level rises and falls, the mooring ropes at the front end and the rear end can be automatically retracted and released through the self-adaptive adjustment of the height of the counterweight driving block according to the rotation transmission of the rotating drum member and the rotating shaft, so that the draft of the floating body is kept unchanged, and the water level rise and fall adjustment is automatically adapted. Meanwhile, the scheme is better than the previous scheme in that a member of a counterweight driving block is saved, and the tensioning force application ends of the front and rear end mooring ropes of the two rotary drum members are coupled to the counterweight driving block through the transmission of the gear and the rotating shaft, so that when one of the two front end mooring ropes is subjected to larger stress, the force can be balanced to the two rear end mooring ropes respectively, and the stress self-adaptive balance adjustment in four directions can be realized, so that the balance stability of the whole bearing system is better, and the overall stability of the device is better.
In particular, other local details and functions of the present floating facility may be consistent with previous self-positioning floating facility structures, and will not be described herein in detail.
Therefore, the scheme of the invention can realize plane constraint positioning of the water floating facility at different water levels and different flow rates. In the prior patent scheme of the applicant, a weight is hung by using a pulley, and the pulling force of a cable is constant all the time, so that the floating facility must be shifted to generate an angle change to offset the water flow force, and the prior patent scheme only can realize micro-drifting but cannot realize accurate positioning by reasonably setting the weight of the weight. According to the scheme, the water flow force is counteracted through elastic deformation and internal force adjustment of the mooring ropes at the front end and the rear end, so that the requirement for accurate positioning can be met by the floating facility as long as the two mooring ropes have the mooring rope force. Meanwhile, the invention can realize automatic retraction of the mooring rope under the super-large water level amplitude. In the prior patent application scheme of the applicant, the weight is hung by the pulleys, so that the cable cannot be shortened and collected proportionally, and the weight block needs to be placed in water, so that the uncertainty is increased too much. Through the mode of big minor axis in this application scheme, realized that the proportion of hawser shortens to receive and release, and the heavy object piece is arranged in the box, conveniently changes and overhauls.
In conclusion, the invention has the advantages of realizing the accurate positioning of the floating platform and better adapting to the lifting change of the water level.

Detailed Description
The present invention will be described in further detail with reference to specific embodiments.
Example 1: a floating type device with self-adaptive water level lifting and plane constraint positioning is disclosed, as shown in figures 1-4, comprising a floating platform 1 floating on the water surface, and a self-positioning system of the floating platform, wherein the self-positioning system of the floating platform comprises a front end cable 2 arranged at one end of the floating platform facing to the water flow direction and a rear end cable 3 arranged at one end opposite to the water flow direction, the lower end of the front end cable 2 is obliquely and forwardly anchored under the water, the lower end of the rear end cable 3 is obliquely and rearwardly anchored under the water, the self-positioning system of the floating platform also comprises a drum member 4 horizontally arranged along the water flow direction, the drum member 4 is rotatably arranged on the floating platform 1, the front end of the drum member is provided with a front end cable winding section, the upper end of the front end cable 2 is wound on the front end cable winding section, the rear end of the drum member is provided with a rear end cable winding section, the upper end and the front end cable 3 are wound on the rear end cable winding section in the same direction, the middle of the rotating drum component 4 is provided with a counterweight lifting rope winding section, a lifting rope 5 is wound on the counterweight lifting rope winding section in the direction opposite to the front end cable rope, and a counterweight driving block 6 is suspended below the lifting rope 5.
When the device is used, the gravity of the counterweight driving block is relied on, and a pretension force is applied to the cables at the front end and the rear end through the torque conversion of the drum component, so that the cables are tensioned and balanced, and the floating platform is kept still. When the front end of the floating platform is impacted by water flow, the force applied to the cable at the front end is increased, and the magnitude and the direction of the torque generated by the counterweight driving block suspended on the other side of the rotary drum are unchanged, so that the magnitude of the overall torque at the cable side is unchanged. Therefore, the pre-tension of the cable at the other end is reduced due to the fact that the stress of the cable at the front end is increased, the moments at two sides of the rotary drum component are kept balanced continuously, the floating platform keeps horizontal displacement unchanged (only tiny displacement is carried out in the deformation range of the cable), and accurate plane positioning constraint under the water flow impact state is achieved. Meanwhile, when the water level rises and falls, the self-adaptive adjustment of the retraction and release of the mooring rope is realized through the rotation of the rotating drum member, the height of the counterweight driving block is changed but the moment is not changed when the rotating drum rotates, so the retraction and release lengths of the mooring rope at the front end and the rear end of the other side of the rotating drum member are correspondingly adjusted but the moment is still kept unchanged, and the draft of the floating platform is not changed. Therefore, the self-positioning system of the floating platform can be better ensured to be self-adaptively adjusted according to the water level change, and the balance of the tensioning stress system is kept unchanged in the adjusting process.
More specifically, in the daily operation of the floating facility on water, the force applied to the floating platform mainly includes the self-gravity, buoyancy, water flow force, wind force, wave force and the like of the floating platform. In this scheme, the floating platform is offset from gravity by the buoyancy that the floating platform displacement volume produced. The water flow force, the wind force and the wave force are applied to the fore-and-aft cable by the counterweight driving block and are counteracted by self-adaptive adjustment of the internal force of the cable. Meanwhile, the zero-gravity high-strength cable is adopted, the cable is in a tensioning and straightening state in water, and the drifting displacement of the cable is mainly generated by elastic deformation caused by the change of the internal force of the cable, so that the plane constraint positioning of the floating platform is realized. The principle of the cable-stayed bridge is similar to that of a cable-stayed bridge, the change of the load of the bridge mainly causes the change of the internal force of each cable, but the influence of the whole deformation of the bridge is small. Therefore, the pretension force of the mooring rope in the scheme is applied by the counterweight driving block connected with the mooring rope in the floating platform, and the weight of the counterweight driving block is determined according to the designed water flow force, the wind force and the wave force and the direction. When the water level rises and falls, the cable is retracted and released through the movement of the transmission mechanism in the floating platform and the counterweight driving block, so that the cable is always kept in a straightening state, the floating platform is lifted along with the water level at a set reference position, and when the floating platform is used for pier collision avoidance protection, the floating platform can be kept in a non-contact state with a pier, and the pier load is not increased. The invention provides a self-adaptive water level lifting and plane constraint positioning method for an over-water floating facility, which adopts a self-balancing principle, realizes self-coupling locking between two symmetrically arranged cables by utilizing a mechanical structure, and realizes self-adjustment and self-adaptation under different water levels and flow speed conditions.
Of course, as other possible embodiments, the counterweight driving block in the above-mentioned embodiment may be changed into a spring member with a lower end fixed on the floating platform, or the upper end of the front end cable and the upper end of the rear end cable may be directly connected to two ends of a spring member on the floating platform, but this structure is not highly stable in force balance, and it is difficult to achieve adaptive adjustment according to the water level change.
In this embodiment, the fixed pulleys 7 are respectively installed on the lower surfaces of the floating platforms corresponding to the front end cable winding section and the rear end cable winding section, and the front end cable 2 and the rear end cable 3 are respectively wound and connected with the drum member upwards after passing through the corresponding fixed pulleys.
Therefore, the oblique tension of the mooring rope is converted into vertical force through the direction change of the fixed pulley, and the condition that the stress of the rotary drum component is more balanced and stable is ensured.
Wherein the fixed pulley 7 is mounted on a fixed pulley seat which can rotate horizontally.
Thus, the convenient cable can be opened to form a certain angle so as to better keep balance and stability.
Wherein, a vertical soft sleeve 8 is arranged between the fixed pulley 7 and the drum component 4, and the front end cable 2 and the rear end cable 3 respectively pass through the corresponding soft sleeve and are connected with the drum component.
In this way, the cable can be better protected.
The front end cable winding section and the rear end cable winding section are arranged in an equal diameter mode, and the diameter of the front end cable winding section and the diameter of the rear end cable winding section are larger than the diameter of the counterweight lifting rope winding section.
Therefore, the diameter proportion of each section of the drum member can be changed to realize the proportional adjustment of the retracting length and distance of the cable, and the length of the lifting rope required by the counterweight driving block is reduced.
Wherein, a pod is arranged on the floating platform 1, and the counterweight driving block 6 is suspended in the pod.
Therefore, the balance weight driving block can not be impacted by water flow to influence the stress balance, and the maintenance is more convenient. Certainly, when implementing, also can suspend the counter weight drive block in the water below the floating platform in midair, but easily receive rivers impact influence like this, and be unfavorable for the maintenance.
Wherein, the rotary drum component 4 is rotatably arranged on a supporting frame 9 through a bearing, and the supporting frame 9 is fixed on the floating platform.
Thus, the structure is simple and the installation is convenient.
The front end cable winding section and the rear end cable winding section are respectively provided with an axially sliding sleeve 10 by means of splines, and the front end cable and the rear end cable are wound on the corresponding sliding sleeves 10.
Therefore, when the mooring rope is automatically retracted and released along with the water level change, the mooring rope and the contact side edge position of the rotary drum component are always positioned right above the fixed pulley through the axial sliding automatic adjustment of the sliding sleeve, the influence of the inclination of the mooring rope on the stress balance is avoided, and the stability and the reliability of a balanced stress system are better ensured.
The floating platform self-positioning system comprises two sets of floating platform self-positioning systems, wherein the rotary drum members of the two sets of floating platform self-positioning systems are horizontally arranged in parallel at intervals, and the front end cable and the rear end cable of each of the two sets of floating platform self-positioning systems are respectively connected to the opposite sides or the opposite sides of the two rotary drum members.
Therefore, when the front end cable of the single set of floating platform self-positioning system is impacted by water flow, the front end cable and the rear end cable are stressed differently, the stress difference of the same-direction side surfaces in the front and rear directions of the rotary drum component can generate torque in the horizontal direction, the rotary drum is rotated, and the floating platform is rotated. Therefore, after the improvement, the torques generated by the two sets of floating platform self-positioning systems can be just counteracted mutually, and the stability of the floating platform is better ensured.
Wherein, the lower ends of the front end cable and the rear end cable are respectively fixed on the corresponding anchor ingots 11 at the water bottom.
Therefore, the folding and unfolding are convenient to fix and control.
Example 2: this embodiment differs from embodiment 1 only in that the apparatus is implemented in a slightly different configuration, and this embodiment is implemented by the adaptive water level elevation and level restriction positioning floating apparatus shown in fig. 5-6, which includes a floating platform 1 'floating on the water surface, and further includes an adaptive floating platform positioning self-adjusting system, which includes two drum members 4' horizontally juxtaposed and spaced apart, the drum members 4 'being arranged in the direction of the water flow and rotatably mounted on the floating platform, the drum members having a front cable winding section at their front ends and winding front cables 2', the drum members having a rear cable winding section at their rear ends and winding rear cables 3 ', the lower ends of the front cables 2' being anchored under water obliquely to the front and lower directions facing the water flow, the lower end of the rear end mooring rope 3' is anchored under water in a backward and downward inclined manner in the direction departing from the water flow; the front end cable and the rear end cable of each of the two rotary drum components are connected to the side face, away from the two rotary drum components, of the two rotary drum components in a winding mode, a driving bevel gear 7 'is installed in the middle of each rotary drum component, the two driving bevel gears 7' are respectively meshed with two driven bevel gears 8 'installed on the same rotating shaft 9', the rotating shaft 9 'is rotatably and horizontally installed on the floating platform and is vertically arranged between the two rotary drum components, a lifting rope is further wound on the rotating shaft, and a counterweight driving block 6' is arranged below the lifting rope in a hanging mode.
Thus, in comparison with embodiment 1, the adaptive water level raising and lowering and planar restraining positioning floating device used in this embodiment can apply a pretension force to the front and rear cables of the two drum members to tension them, based on the gravity of the counterweight driving block, through torque conversion and transmission. Therefore, when the floating platform is impacted by water flow, as long as the impact acting force of the water flow is smaller than the pretension force of the mooring rope, the floating platform can hardly generate horizontal displacement. The influence of stormy waves can be avoided, and the precise positioning of the floating platform can be realized. Meanwhile, when the water level rises and falls, the mooring ropes at the front end and the rear end can be automatically retracted and released through the self-adaptive adjustment of the height of the counterweight driving block according to the rotation transmission of the rotating drum member and the rotating shaft, so that the draft of the floating platform is kept unchanged, and the water level rising and falling adjustment is automatically adapted. Meanwhile, the embodiment is better than the embodiment 1 in that not only a member of a counterweight driving block is saved, but also the front and rear end cable tension force application ends of two drum members are coupled to the counterweight driving block through the transmission of gears and rotating shafts, so that when one of the two front end cables is subjected to a large force, the force can be balanced to the two rear end cables respectively, and therefore adaptive balance adjustment of the force in four directions can be realized, the balance stability of the whole force bearing system is better, and the overall stability of the device is better.
In specific implementation, other local detailed structures and functions of the floating facility can be consistent with those of the self-positioning floating facility structure in the embodiment 1, and are not described in detail here.
The principle of the invention is further explained below by referring to the schematic diagrams of the principle of stress analysis of the self-positioning floating facility in the states of still water and water flow (see fig. 7 and 8).
The plane constraint positioning principle of the self-positioning floating facility is as follows:
by adjusting the weight of the counterweight driving block, the plane displacement of the floating body is within the range of the required restraint positioning precision under the action of water flow. The control index of the plane displacement constraint positioning precision of the floating body is deltamax，δmaxThe smaller the plane constraint positioning accuracyIs high. And obtaining the minimum weight of the counterweight driving block according to the floating body balance equation and the constraint equation so as to enable the plane displacement of the floating body under the action of water flow to meet the requirement.
Referring specifically to FIGS. 7-8, the reference numbers in the figures and in the equations below are designated G1Float weight (other members than counterweight drive blocks), G2Counterweight driving mass weight, FfBuoyancy of the float, F1Force of water flow, T1-floating body bow cable tension, T2-floating body stern line tension, α1Angle of casting of bow rope, α2Stern hawser casting angle, L1Bow cable throwing length, L2Stern line length, delta-plane translation under the action of float current, R-radius of third rotor, R1First radius of rotation, R2Second rotor radius, δmax-float plane constraint positioning accuracy.
Referring to fig. 7, when there is no water flow impact force, the relationship of force balance can be obtained:
Ff＝G1+G2+T1 cosα1+T2 cosα2
T2 sinα2＝Ti sinα1
meanwhile, the moment balance equation of the internal counterweight driving block of the floating body can be obtained:
G2r＝T1 R1+T2 R2。
referring to fig. 8, when there is water flow acting force, the displacement change of the floating body in the water flow direction is delta, and can be obtained according to the stress balance and the moment balance:
Ff′＝G1+G2+T1′cosα1′+T2′cosα2′
F1+T2′sinα2′＝T1′sinα1′
G2r＝T1′R1+T2′R2
the plane displacement of the floating body is smallUnder the condition, the effective drainage volume of the floating body is not greatly changed, and F can be considered asf＝Ff', then:
T1 cosα1+T2 cosα2＝T1′cosα1′+T2′cosα2′
according to the geometric relationship, the change theta of the opening angle of the mooring rope at the bow part of the floating body before and after the action of the water flow is obtained1Stern part cable flare angle change theta2Comprises the following steps:
θ1＝α1′-α1
θ2＝α2-α2′
under the condition of small plane displacement of the floating body, the plane displacement delta of the floating body and the field angle change theta of the mooring rope at the bow part1Stern part cable flare angle change theta2Smaller, then:
δ≈θ1L1＝(α1′-α1)L1
δ≈θ2L2＝(α2-α2′)L2
the plane constraint positioning precision of the floating body is deltamaxI.e. the displacement of the floating body plane does not exceed delta under the action of water flowmax. According to the above equation, establishing the optimal determination equation system of the floating body plane constraint positioning accuracy as follows:
in the formula, R and R1、R2、α1、α2、L1、L2Known as the water flow force F1Can be determined from measured or empirical values, alpha1′、α2′、T1′、T2' unknown, using an optimization method, from the above equation set, to obtain G2 0. I.e. the weight of the counterweight driving mass is set to G2 0Can ensure that the plane displacement constraint change of the floating body does not exceed deltamax. (in practice when the water level is not changed,the length of the fore-aft cable is changed due to the change of the tension of the cable, and the elongation caused by the change of the tension of the cable is related to the rigidity of the cable, so an equation of the elongation of the cable and the elastic modulus of the cable is also introduced. )
For how the self-positioning floating facility realizes self-adaptive water level lifting, the self-positioning floating facility can adapt to water level amplitude variation by adjusting the diameter ratio of the first rotating piece to the third rotating piece and the diameter ratio of the second rotating piece to the third rotating piece. The following is specifically described in conjunction with the formula, where the formula is expressed in terms of the following symbols: r-radius of third rotating member, R1-first radius of rotation, R2Radius of the second rotating member, H-amplitude of water level, L1Length of throwing of the mooring line at the bow of the float at low water level, L2Low water level float stern line cast length, L1' -length of the cables at the bow end of the floating body at high water level, L2' -the length of the cable at the stern end of the floating body at high water level is obtained according to the cosine law:
the obtained elongation of the bow end cable and the stern end cable is respectively as follows:
ΔL1＝L1′-L1
ΔL2＝L2′-L2
the displacement of the internal counter weight drive block of the corresponding body is delta P, because the rotation angles of the first, second and third rotation pieces are equal, then:
the maximum displacement height of the counterweight driving block in the floating body is set to be delta PmaxAnd then:
the above formula is the ratio of the first rotating member to the third rotating member in terms of the difference in diameter
The ratio of the second rotating member to the third rotating member is different from the ratio
The limitation of (2). The adaptive capacity of the floating body to the amplitude of large water level is realized under the condition of small displacement of the third rotating member by setting the reducing ratio meeting the condition.
In addition, when the invention is implemented, if the flow rate of the unidirectional water flow is small, a single-shaft working mode can be adopted, namely, a cable is respectively arranged in front of and behind along the water flow direction and is tensioned. When the flow rate of the one-way water flow is larger, a plurality of sets of single-shaft systems can be arranged to resist the water flow. Two or more cables are respectively arranged in front of and behind the water flow direction and are tensioned.
The single-shaft system can only adapt to the condition of one-way flow velocity, namely, the fore-aft cable and the flow velocity direction are coplanar, when transverse flow or multi-directional flow exists, if the single-shaft system is still used, the transverse flow cannot be resisted, and transverse displacement can occur under the condition of the transverse flow couple. It is also possible to provide a plurality of independent single axis systems to provide improved resistance to small cross flows by arranging the cables in a splayed arrangement (e.g. in phantom in fig. 1) or in a crossed arrangement (i.e. the cables in phantom in fig. 1 may be arranged in a crossed arrangement).
In addition, when the water flow is multi-directional, the stability of the water flow cannot be kept only by arranging the cables, namely, the multi-shafts can be linked to resist the action of the multi-directional flow.
Therefore, the scheme of the invention can realize plane constraint positioning of the water floating facility at different water levels and different flow rates. In the prior patent scheme of the applicant, a weight is hung by using a pulley, and the pulling force of a cable is constant all the time, so that the floating facility must be shifted to generate an angle change to offset the water flow force, and the prior patent scheme only can realize micro-drifting but cannot realize accurate positioning by reasonably setting the weight of the weight. In the scheme, the water flow force is counteracted through the elastic deformation and the internal force adjustment of the cables at the front end and the rear end, so that the requirement on accurate positioning can be met by the floating facility as long as the two cables have cable forces. Meanwhile, the invention can realize the automatic winding and unwinding of the mooring rope under the super-high water level amplitude variation. In the prior patent application scheme of the applicant, the weight is hung by the pulleys, so that the cable cannot be shortened and collected proportionally, and the weight block needs to be placed in water, so that the uncertainty is increased too much. Through the mode of big minor axis in this application scheme, realized that the proportion of hawser shortens to receive and release, and the heavy object piece is arranged in the box, conveniently changes and overhauls.
