Description

Technical Field

[0002] Compared with onshore photovoltaics, offshore photovoltaics have become one of the main development directions of photovoltaic power generation due to its advantages of not being constrained by land resources and fully utilizing solar energy resources. When constructing an offshore photovoltaic project, it is first necessary to carry out pile foundation construction at sea; after the pile foundation construction is completed, the upper brackets and photovoltaic modules can be installed. If the position and elevation of the pile foundation deviate during construction, it will seriously affect the installation of the later brackets and photovoltaic modules, affecting the construction progress.

[0003] In the prior art, total stations and levels are usually used as the main measuring tools to determine the position and elevation of pile foundations, and the penetration degree of the pile foundation is used as a verification method; on the other hand, the control of the plane position of the pile foundation is mainly based on the GPS device on the piling platform.

[0047] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0051] As mentioned in the background technology, the control of the pile top elevation and the pile foundation plane position is the key and difficult point of offshore construction. In the prior art, the control of the pile top elevation and the pile foundation plane position by total station and GPS may have large errors, and if the offshore environment is complex, for example, there are natural factors such as waves, tides and wind, it will increase the difficulty of controlling the pile top elevation and the pile foundation plane position.

[0052] In order to solve the above problems, the embodiment of the utility model provides an offshore photovoltaic pile driving control device, which can accurately control the plane position of the pile foundation by setting a distance measuring component on the pile frame and measuring the distance to the constructed pile foundation through the distance measuring component. In addition, the distance measuring component includes multiple distance measuring units and observation processing units. When piling, the multiple distance measuring units and observation processing units can accurately control the pile foundation top elevation. The offshore photovoltaic pile driving control device provided by the embodiment of the utility model makes the control process of the pile foundation top elevation and the pile foundation plane position more accurate and convenient.

[0053] The offshore photovoltaic pile driving control device provided by the utility model is described in detail below in conjunction with specific embodiments.

[0054] Reference Figure 1 As shown, Figure 1 The schematic diagram of the structure of the offshore photovoltaic pile driving control device provided by the embodiment of the utility model. The offshore photovoltaic pile driving control device provided by the embodiment of the utility model comprises a pile driving platform 100, a pile driving assembly 200 and a distance measuring assembly 300; wherein the pile driving assembly 200 comprises a first pile frame 210, a pile hammer 220, a steel wire rope 230 and a top support 240.

[0055] In the embodiment of the present invention, the top of the first pile frame 210 is connected to the top support portion 240 , the bottom of the first pile frame 210 is disposed on the piling platform 100 , and the first pile frame 210 is perpendicular to the piling platform 100 .

[0056] Optionally, the top of the first pile frame 210 and the top support portion 240 may be connected by welding or by bolting, which is not specifically limited in this embodiment.

[0057] In addition, a pulley is provided inside the top support part 240 , and the pile hammer 220 is connected to the pulley inside the top support part 240 via a steel wire rope 220 to perform pile driving construction on the pile foundation.

[0058] In the embodiment of the present utility model, the distance measuring component 300 includes a plurality of distance measuring units 310 and an observation processing unit 320. Figure 1As shown, a plurality of distance measuring units 310 are sequentially arranged on the first pile frame 210 in the vertical direction. Each distance measuring unit 310 includes a connection assembly 400 and a distance meter 312 , and the distance meter 312 is arranged on the first pile frame 210 via the connection assembly 400 .

[0059] In addition, the observation processing unit 320 is electrically connected to the plurality of distance meters 312 to obtain the measurement data of the plurality of distance meters 312 to determine the plane position of the pile foundation and the pile top elevation.

[0060] Optional, see Figure 1 As shown, the multiple rangefinders 312 and the observation processing unit 320 can be connected via a data line 604 so that the observation processing unit 320 can obtain the measurement data of the multiple rangefinders 312 .

[0061] As an optional embodiment, the observation processing unit 320 may include a display. After receiving the measurement data from the multiple rangefinders 312, the observation processing unit 320 may display the multiple measurement data for the convenience of construction personnel to view.

[0062] The following will describe how to use the offshore photovoltaic pile sinking control device provided by the embodiment of the utility model to achieve the control process of the plane position of the pile foundation and the pile top elevation:

[0063] It is understandable that in the actual construction process, the plane position of the pile foundation needs to be controlled first, and then the pile driving can be carried out after the plane position of the pile foundation is determined, and the elevation of the pile top can be further controlled.

[0064] When controlling the plane position of the pile foundation, it is necessary to determine whether the current pile foundation to be constructed and the constructed pile foundation have reached the planned spacing for pile foundation construction. Therefore, it is possible to determine whether the current pile foundation to be constructed 602 and the constructed pile foundation 600 have reached the planned spacing for pile foundation construction by using the distance meter 312 provided on the first pile frame 210. When the measurement data of the distance meter 312 reaches the planned spacing, it can be determined that the plane position of the current pile foundation to be constructed has been controlled.

[0065] Optionally, the rangefinder 312 may be a laser rangefinder, an infrared rangefinder, or other rangefinders that can implement the present invention.

[0066] In some embodiments, in order to control the top elevation of the pile foundation, multiple distance meters 312 are horizontally arranged on the first pile frame. It should be noted that among the multiple distance meters 312, the installation height of the lowest distance meter 312 should be the lower limit height of the top elevation of the pile foundation, and the installation height of the next lowest distance meter 312 should be the upper limit height of the top elevation of the pile foundation.

[0067] In the actual piling process, as the pile hammer 220 drives the pile foundation, the measurement data of multiple distance meters 312 gradually change from top to bottom, until the measurement data of the distance meters 312 above the second uppermost position changes while the measurement data of the lowest distance meter 312 does not change, indicating that the pile top elevation of the current pile foundation is within the allowable error range of the planned elevation, and at this time, the pile top elevation control of the pile foundation is completed.

[0068] The offshore photovoltaic pile driving control device provided by the embodiment of the utility model includes: a pile driving platform, a pile driving assembly and a distance measuring assembly; wherein the pile driving assembly includes a first pile frame, a pile hammer, a wire rope and a top support; the top of the first pile frame is connected to the top support, the bottom of the first pile frame is arranged on the pile driving platform, and the first pile frame is perpendicular to the pile driving platform, and the pile hammer is connected to the top support through a wire rope to perform pile driving construction on the pile foundation; the distance measuring assembly includes a plurality of distance measuring units and an observation processing unit, and the plurality of distance measuring units are sequentially arranged on the first pile frame in the vertical direction, each distance measuring unit includes a connection assembly and a distance meter, and the distance meter is arranged on the first pile frame through the connection assembly; the observation processing unit is electrically connected to the plurality of distance meters to obtain the measurement data of the distance meter, and determine the plane position of the pile foundation and the pile top elevation. In the embodiment of the utility model, the distance to the constructed pile foundation is measured by the distance measuring assembly, and it is judged whether the distance reaches the planned spacing to complete the precise control of the plane position of the pile foundation. In addition, when piling is being carried out, precise control of the pile foundation top elevation can be achieved through changes in the measurement values ​​of the multiple distance measuring units, making the control process of the pile foundation top elevation and the pile foundation plane position more accurate and convenient.

[0069] However, since the pile foundation may be temporarily tilted during the construction process, measurement errors may occur. In order to avoid this situation, the offshore photovoltaic pile sinking control device provided by the embodiment of the utility model, in a possible implementation method, multiple rangefinders 312 are set at an acute angle to the horizontal plane, referring to Figure 1 As shown, the multiple rangefinders 312 are arranged at an acute angle to the horizontal plane.

[0070] If multiple distance meters 312 are arranged at an acute angle to the horizontal plane, then before the pile foundation construction, it is necessary to calculate the first value 601 of the distance meter 312 when the pile foundation construction is completed according to the planned spacing of the pile foundation construction, the angle between the distance meter 312 and the horizontal plane, and the trigonometric function. When the plane position of the pile foundation is controlled, when the measurement data of the distance meter 312 is the first value 601, the plane position control of the pile foundation is completed.

[0071] Reference Figure 2 As shown, Figure 2It is a schematic diagram of the pile foundation construction process provided by the embodiment of the utility model. It is understandable that when the plane position control of the pile foundation is completed, the pile foundation 602 to be constructed can be hoisted and prepared for piling. At this time, the measurement data of the multiple rangefinders becomes the second value 603.

[0072] It is understandable that, in order to ensure that the pile top elevation of the pile foundation is within the allowable error range of the planned elevation, in some embodiments, the distance between the second lowest distance meter and the lowest distance meter is related to the allowable error of the pile top elevation. Specifically, before the pile foundation is constructed, the installation height of the lowest distance meter 312 and the installation height of the second lowest distance meter 312 can be calculated according to the planned elevation, the allowable error range of the planned elevation, the angle between the distance meter and the horizontal plane, and the trigonometric function, so that when the pile top elevation of the pile foundation reaches the planned elevation, the measurement data of the second lowest distance meter 312 is the first value 601 and the measurement data of the lowest distance meter remains the second value 603.

[0073] Figure 3 This is a schematic diagram of the pile foundation to be constructed according to the embodiment of the utility model after the piling is completed. Figure 2 and Figure 3 As shown, along with the pile hammer 220 driving the pile, the measurement data of the plurality of distance meters 312 change from the first value 601 to the second value 603 from top to bottom, until the measurement data of the next lower distance meter 312 is the first value 601 and the measurement data of the lowest distance meter remains the second value 603. At this time, the pile top elevation of the pile foundation 602 to be constructed reaches the planned elevation, and the plane position and pile top elevation control of the pile foundation 602 to be constructed are completed.

[0074] In the offshore photovoltaic pile driving control device provided by the embodiment of the utility model, multiple rangefinders are set at an acute angle to the horizontal plane when installed, thereby avoiding measurement errors caused by a temporary tilt of the pile foundation, and the multiple rangefinders can determine whether the measurement data is the target value when controlling the planar position of the pile foundation, so that the control of the planar position of the pile foundation is more precise.

[0075] Reference Figures 1 to 3 As shown in the figure, it can be seen that in the embodiment of the utility model, multiple distance meters 312 are arranged in sequence in the vertical direction in a sparse upper and dense lower manner, and the lower the distance meters are, the denser the arrangement is. Based on this, the pile driving force of the pile hammer 220 can be controlled according to the changes in the measurement data of the multiple distance meters 312 during the pile driving process. When the measurement data of the upper distance meter 312 changes, the pile hammer 220 is controlled to apply a larger pile driving force. When the measurement data of the lower distance meter 312 changes, the pile hammer 220 is controlled to apply a smaller pile driving force. The pile driving force is gradually reduced, which can improve the accuracy of realizing the control of the pile foundation pile top elevation.

[0076] In the actual construction process, the allowable error range of the planned elevation may be very small, even smaller than the width of the distance meter 312. If multiple distance meters are arranged in parallel at this time, the distance between the lowest and second lowest distance meters 312 will exceed the allowable error range of the planned elevation. Therefore, in the embodiment of the utility model, except for the two lowest distance meters 312, the other distance meters are arranged in parallel; and the angle between the second lowest distance meter 312 and the horizontal plane is greater than or equal to the angle between the lowest distance meter 312 and the horizontal plane.

[0077] Please refer to Figure 4 , Figure 4 A schematic diagram of another pile foundation to be constructed provided in an embodiment of the utility model is provided with completed piling, wherein the angle between the lowest distance meter 312 and the horizontal plane is smaller than the angle between the next lowest distance meter 312 and the horizontal plane. This design can control the allowable error of the planned elevation within a very small range.

[0078] It is understandable that in the above embodiment, the control of the angle and height of the rangefinder 312 is crucial, that is, the connection assembly 400 needs to be able to achieve a detachable connection between the rangefinder 312 and the first pile frame, and can control the angles of multiple rangefinders 312 and the horizontal plane.

[0079] The following reference Figures 5 to 10 The connection method of the connection component 400 is described as follows:

[0080] The first possible way to achieve this is to refer to Figures 5 to 8 :

[0081] Figure 5 is a schematic diagram of the structure after the connection component 400 is assembled. Figure 6 is a schematic structural diagram of the angle control unit 410, Figure 7 is a schematic diagram of the structure of the connection base plate 420, Figure 8 The schematic diagram of the structure of the rangefinder installed on the connection assembly is shown in FIG. The connection assembly 400 includes an angle control unit 410 and a connection base plate 420; the angle control unit 410 includes a gear unit 411 and a screw 412, the screw 412 is located below the gear unit 411, and the gear unit 411 is provided with a plurality of first through holes 413. The connection base plate 420 is provided with a gear groove 421 and a second through hole 422 matching the gear unit, and a third through hole 423 is provided in the gear groove 421.

[0082] For ease of understanding, the detachable connection between the rangefinder 312 and the connecting assembly 400 is first introduced. Figures 6 to 8 , a plurality of connecting pieces 605 may be provided on the rangefinder 312 , and then bolts may be used to pass through the connecting pieces 605 and the first through holes 413 to achieve a detachable connection between the rangefinder 312 and the connecting assembly 400 .

[0083] After the rangefinder 312 is fixed to the angle control part 410 , the screw rod 412 is passed through the third through hole 423 in the gear groove 421 and fixed to the nut, so that the detachable connection between the angle control part 410 and the connecting base plate 420 can be achieved.

[0084] Furthermore, the connecting bottom plate 420 is connected to the first pile frame 210 .

[0085] Optionally, the connection bottom plate 420 and the first pile frame 210 may be fixed by welding, or may be detachably connected by bolts through the second through holes 422 on the connection bottom plate.

[0086] The following describes how to control the angle in this implementation:

[0087] Please continue to refer to Figures 5 to 8 In the embodiment of the utility model, each tooth of the gear part 411 has the same shape, and the distance between adjacent teeth is equal, so that the gear part can be set in the gear groove 421 when changing different positions. After the rangefinder 312 is fixed to the angle control part 410, the angle can be changed by rotating the angle control part 410 to place each tooth of the gear part 411 in different grooves of the gear groove 421. When the angle is determined, the angle control part 410 is fixed to the connecting bottom plate 420 by bolts.

[0088] In some embodiments, the angle between every two adjacent teeth of the gear portion 411 may be 3° to 5°.

[0089] The offshore photovoltaic pile driving control device provided by the embodiment of the utility model installs the distance meter to the first pile frame through the connection assembly, wherein the connection assembly is detachably connected to the first pile frame through the connection bottom plate, so that the distance meter unit can achieve height adjustment. In addition, the angle between the distance meter and the horizontal plane can be controlled by adjusting the angle control unit, so that the plane position of the pile foundation and the pile top elevation can be controlled more accurately.

[0090] For the second possible method, please refer to Figures 9 and 10 , Fig. 9 This is a schematic diagram of the structure of the adjustment base plate 430 provided in an embodiment of the utility model. Fig.10 This is a front schematic diagram of the adjustment base plate 430 provided in an embodiment of the present utility model.

[0091] In some embodiments, the connection assembly 400 includes an adjustment base plate 430 , and the adjustment base plate 430 is connected to the first pile frame 210 .

[0092] Optionally, the adjusting base plate 430 and the first pile frame 210 may be fixed by welding or by bolts, which is not limited in this embodiment.

[0093] like Fig. 9 As shown, a plurality of mounting holes 431 are provided on the adjusting base plate 430 , and the rangefinder 312 is connected to the adjusting base plate 430 through some of the mounting holes 431 , wherein different mounting holes 431 correspond to different heights and angles.

[0094] It is understandable that in this implementation, a plurality of connecting plates are also provided on the rangefinder 312, and the rangefinder 312 can be detachably connected to the adjustment base plate 430 by using bolts through the connecting plates and the partial mounting holes 431. The height and angle of the rangefinder 312 can be adjusted by fixing 312 on different partial mounting holes 431.

[0095] The following describes how to control the height and angle of the rangefinder 312 in this implementation:

[0096] In some embodiments, the plurality of mounting holes 431 are arranged in at least two rings, and two adjacent rings in the at least two rings are at least partially nested with each other in the vertical direction.

[0097] For example, please refer to Fig.10 The multiple mounting holes 431 on the adjusting base plate 430 are arranged in four rings. For easy distinction, the center of each ring is indicated by a dotted line.

[0098] In some embodiments, the mounting hole at the center of each ring is used as the mounting hole for adjusting the height, and the mounting holes at other positions are used as the mounting holes for adjusting the angle. During installation, a connecting piece can also be set at the center of the rangefinder, and then bolts are used to fix it through the connecting piece set at the center and the mounting hole at the center of the ring, and the centers of different rings indicate different heights.
