Description

Technical Field

[0001] The invention relates to the technical field of marine engineering equipment manufacturing, in particular to an on-water photovoltaic adjustable buoy construction platform. Background Art

[0002] When installing photovoltaic power generation on water, a construction platform needs to be built. The construction platform is generally assembled with buoys. The general buoy construction platform is made by fixing multiple buoys or multiple buoys with scaffolding. Figure 1 As shown, it is used as a photovoltaic power generation construction platform. However, when constructing on water such as the sea or lake, we often encounter various situations. Take the project undertaken by our company as an example: The normal water storage level of Tiangang Lake is 13.3 meters, and the flood level once in 50 years is 16.43 meters. The designed pile top elevation of the project is 16.23 meters, the column height is 1.5 meters, and the photovoltaic panel is 0.2 meters away from the top of the column. According to the normal water storage level of 13.3, the construction working surface of the project is 16.23 meters-17.93 meters, and the construction working surface is between 2.9 meters and 4.6 meters.

[0003] According to the information obtained from the Tiangang Lake Water Conservancy Management Service Station, the water level of Tiangang Lake is adjusted by the Water Conservancy Bureau based on the overall situation, and the water level of Tiangang Lake changes every day. Therefore, during the construction of this project, the height of the working surface from the water surface may fluctuate.

[0004] The water level of the project was 13.54 meters during construction. Figure 1 The construction platform shown in the figure entered the rainy season in mid-July, and the water level of Tiangang Lake rose by 2 meters, resulting in the construction platform being too high. The column welding construction surface was located at the bottom of the construction platform, making it impossible to carry out construction. 20 construction platforms need to be reconstructed. The original steel pipes were too long and all were cut and reassembled. Each construction platform required 2 people to modify for 2 days, which was time-consuming, labor-intensive and material-intensive. If the water level continues to drop or rise, the height of the reconstructed construction platform will still not meet the construction requirements, and the construction platform will still need to be reconstructed in the later stage.

[0005] In addition, scaffolding has many buckle installation components and many connecting parts for each column, which poses a great safety hazard. A crane is needed for lifting, and the ship needs to go to the dock. The lifting fee includes the crane usage fee and the loss of work time for the round trip and lifting, which makes the cost high.

[0006] In addition, the Water Conservancy Bureau adjusts the water level in a small area every day, and the construction platform with a fixed height cannot be used, affecting the construction progress.

[0007] Before each installation, materials need to be carried via ladders or thrown directly onto the construction platform, which can damage the photovoltaic panels and materials, and also pose a safety hazard when using ladders.

[0008] Since photovoltaic panels are installed in an inclined state, a bench or stepladder needs to be placed on the construction platform each time they are installed. This is unstable and will shake during use. If a narrow platform is built directly under the photovoltaic panels, the safety hazard factor is relatively high.

[0009] On this basis, the present invention provides an on-water photovoltaic adjustable buoy construction platform to solve the above technical problems. Summary of the invention

[0049] The water storage level of this project was 13.54 meters during construction. The early construction platform used a pontoon base and the upper structure was constructed with steel pipes with a height of 2.5 meters.

[0050] The present invention adopts an adjustable floating photovoltaic buoy construction platform, which includes a plurality of buoys 4 arranged side by side and then fixed with L-shaped angle steels 5 around to form a row of buoy bases, and then three rows of buoy bases are put together and fixed with angle steels 5 to form a buoy base 1.

[0051] An operating base 2 is fixed on the upper end surface of the buoy base 1, specifically, an operating panel is fixed on the angle steel 5 on the buoy base 1, and a supporting system is fixed on the operating base 2, specifically, five vertical steel pipes 6 evenly distributed at both ends, the steel pipe 6 is a DN48 round pipe, the steel pipe 6 is fixed on the angle steel 5, and a circular hole for installing the steel pipe 6 is reserved on the corresponding operating panel, a round pipe 7 is slidably sleeved up and down on the outer side of the steel pipe 6, the inside of the round pipe 7 is a cavity, the round pipe 7 is a DN60 round pipe, and a construction base 8 is fixed on the upper end of the round pipe 7, specifically, including an upper frame fixed on the upper end of the round pipe 7, a plurality of horizontal base plates are fixed on the upper frame, a plurality of vertical bottom plates are fixed on the base plate, a construction plate is fixed on the bottom plate, and a fence is fixed around the construction plate.

[0052] H-shaped fixing frames 9 are fixed at the second and fourth steel pipes 6 at both ends of the operating base 2, a capstan 10 is fixed to the outside of the fixing frame 9, a pulley 11 fixed to the fixing frame 9 is provided on the inside of the capstan 10, a pulley 2 12 fixed to the fixing frame 9 is provided at the inner upper end of the pulley 11, a steel wire rope 13 is wound around the capstan 10, and the steel wire rope 13 is fixed to the lower end of the round tube 7 after passing through the pulley 11 and the pulley 2 12.

[0053] A telescopic ladder is fixed on the front side of the construction base 3 and the operating base 2. Specifically, the front side of the construction base 3 includes a vertical upper ladder column 14, and a plurality of transverse upper ladder rods 15 are fixed to the inner side of the upper ladder column 14. A lower ladder groove 16 is fixed on the front side of the operating base 2, and a plurality of lower ladder rods 17 are fixed to the outer side of the lower ladder groove 16. The upper ladder column 14 is slidably installed in the lower ladder groove 16.

[0054] It should be noted that, in order to increase the overall stability, cross-type diagonal braces are fixed between the round tubes 7 at both ends of the front and rear ends.

[0055] Specifically, the construction workers installed the main buoy 4, angle steel 5, DN60 round tube 7, DN48 steel tube 6, fixed frame 9, winch 10, pulley 11, pulley 2 12, and wire rope 13. During the rainy season and flood season, in order to adapt to the water level, the construction workers stood on the operating base 2 and turned to the winch 10. The wire rope 13 on the winch 10 was wound, and the wire rope 13 pulled the round tube 7 up through the pulley 11 and the pulley 2 12, and the round tube 7 drove the construction base 3 to rise. On the contrary, the wire rope 13 was released in the reverse direction, and the construction base 3 was lowered under the gravity of its own weight and the gravity of the materials and personnel above, thereby realizing the height adjustment of the construction base 3.

[0056] The material statistics table is as follows:

[0057] List of main parts processing:

[0058] The buoy base 1 is composed of 50*50*5 angle steel 5 oil barrels, with a diameter of 0.6 meters and a height of 0.9 meters. There are 30 oil barrels in total, and each row of 10 oil barrels is reinforced by angle steel 5 to form a cuboid with a length of 6 meters, a width of 0.9 meters, and a height of 0.6 meters. Finally, the three cuboids are welded together to form the buoy base 1.

[0059] The support system of the adjustable telescopic pontoon construction platform is mainly DN48 steel pipe 6 and DN60 steel pipe 7. The DN48 steel pipe 6 is 1.2 meters long and is welded to the angle steel 5 of the pontoon base 1. Five pipes are arranged on each side along the long side, for a total of 10 pipes. After welding, the 1.4-meter-long DN60 round pipe 7 is put on the DN48 steel pipe 6, and a 6-meter-long DN48 steel pipe 6 is welded to each of the DN60 round pipes 7 on both sides.

[0060] The lifting equipment is mainly composed of a pulley 11, a pulley 2 12, a winch 10, a steel wire rope 13 and a fixed frame 9. The installation position is at the second and fourth positions of the five steel pipes 6 on each side. The steel wire rope 13 is connected to the DN60 round pipe 7. The fixed frame 9 is welded into an H-shape with a 60*60*2.5 square pipe. The vertical high column is 1.25 meters high, the vertical low column is 0.5 meters high, and the horizontal support is 0.8 meters long. The manual winch drives the DN60 round pipe 7 to achieve the lifting effect through the pulley 11 and the pulley 2 12 under the drive of the steel wire rope 13.

[0061] The construction base 3 is assembled from an upper frame, a base plate and a bottom plate. The upper frame is arranged vertically with the 6-meter-long DN48 steel pipe 6 in the support system, with a total of 8 pieces. The length of the upper frame is 2.8 meters, and the length of the bottom plate is 4 meters and 2 meters, which are arranged vertically with the steel pipe 6.

[0062] The fence 8 is of insert type, and 13 0.2-meter-long DN40 galvanized steel pipes are welded on the steel pipe 7. The fence 8 is welded with DN32 steel pipes, with a height of 0.8 meters. After being welded into pieces, it is inserted into the DN40 galvanized steel pipe.

[0063] The ladder is welded with C-shaped steel and is divided into two parts. The upper part is 2 meters long and is connected to the upper construction base 3. The lower part is 1.5 meters long and is welded to the base angle steel 5. The grooves of the two parts of the C-shaped steel engage with each other. During the lifting and lowering process of the construction platform, the height of the ladder rises and falls accordingly.

[0064] It should be noted that the construction platform can be equipped with a drive system as needed to provide power for the construction platform, such as a diesel engine combined with oars.

[0065] It should be noted that, in order to realize the rotation of the winch 10, the present invention provides two embodiments.

[0066] In one embodiment, the four winches 10 are a separate system, and each winch 10 is a manual winch. The manual winch is a prior art and has a locking function. When the height is adjusted, the manual winch will be locked to fix the height.

[0067] It should also be noted that in order to better pull the round tube 7 , a chassis 18 is fixed to the bottom end of the round tube 7 , and the steel wire rope 13 is connected to the chassis 18 , so that the steel wire rope 13 can pull the round tube 7 conveniently.

[0068] Another embodiment is provided, which can conveniently rotate four winches 10 at the same time without the need for four people to rotate them, and the round pipe 7 can be raised synchronously, thereby smoothly driving the construction base 3 to rise.

[0069] The inner sides of the two capstans 10 in the same row are coaxially connected with a transmission shaft 19, and a bevel gear 20 is sleeved on the end of each transmission shaft 19. The two bevel gears 20 are meshed with the same reversing bevel gear 21. The inner sides of the two reversing bevel gears 21 on both sides are coaxially connected to a transmission shaft 22, and a rotating wheel 23 is fixedly sleeved on the transmission shaft 22.

[0070] During operation, the rotating wheel 23 only needs to be rotated to synchronously drive the four winches 10 to rotate, thereby pulling and releasing the steel wire rope 13.

[0071] It should also be noted that when the four winches 10 rotate synchronously, the synchronous pulling and releasing of the wire rope 13 is to be achieved, so the rotation direction of the meshing bevel gear 20 and the rotation direction of the winch 10 need to be set, and the locking device of the built-in manual winch of the winch 10 still has a locking mechanism.

[0072] An embodiment of a manual winch is provided. A locking mechanism is shown in the drawings of the specification, but due to the small size of the parts, it cannot be displayed intuitively. The specific principle is that the winch 10 includes a drum, a wire rope 13 is wound around the drum, the drum is coaxially connected to a large capstan gear, the large capstan gear is meshed with a small capstan gear, and a locking pawl is provided at the front end of the small capstan gear for locking the small capstan gear.

[0073] The crank handle of the manual winch drives the capstan pinion coaxially.

[0074] The transmission shaft 19 is coaxially connected to the capstan pinion, and bearing seats are installed on the corresponding transmission shaft 19, transmission shaft 22, bevel gear 20, and reversing bevel gear 21.

[0075] Furthermore, the construction platform floats on the water, so the construction platform must be fixed when in use. The traditional fixing method is to use a rope to be set on the photovoltaic pillar. If the setting method is used for fixing, it can only limit the large-scale movement of the construction platform, and there will still be a small distance of movement. If it is fixed by tightening, the operation is troublesome every time it is tightened. The most important thing is that the rope setting method is often not tight, and the automatic adjustment of the construction platform cannot be achieved.

[0076] At least one locking mechanism is arranged on the construction base 3, and the locking mechanism comprises a locking bottom shell 24, a locking base groove 25 is arranged on the locking bottom shell 24, slide grooves 1 26 are arranged on both sides inside the locking base groove 25, the ends of the slide groove 1 26 are connected with an inclined slide groove 27, two slide grooves 3 28 and slide grooves 4 29 on the same straight line are arranged in the middle of the locking base groove 25, and two adjusting rods 30 are slidably installed in the locking base groove 27, and the two adjusting rods 30 have the same structure, and the ends of the two adjusting rods 30 are hinged, and an adjusting column 1 31 is arranged at the hinge, and the adjusting column 1 31 is slidably arranged in the slide groove 3 28, and the other end of the adjusting rod 30 is hinged with An L-shaped clamping rod 33 is provided with an adjusting column 2 32 at the hinge of the adjusting rod 30 and the clamping rod 33. The adjusting column 2 32 is slidably set in the sliding groove 1 26 and the sliding groove 27. An adjusting column 36 is provided at the hinge of the two clamping rods 33. The adjusting column 36 is slidably set in the sliding groove 4 29. A semicircular clamping ring 34 is fixed to the end of the clamping rod 33, and a clamping tooth 35 is fixed on the inner side of the clamping ring 34. A locking bottom cover 38 that does not affect the internal transmission is buckled on the locking bottom shell 24. Insertion holes are opened on both sides of the upper end of the adjusting column 1 31, and push rods 37 are inserted in the insertion holes. A push rod hole corresponding to the push rod 37 is opened at the upper end of the locking bottom cover 38.

[0077] Better yet, there are four locking mechanisms, which are symmetrically arranged on the construction base 3, with two on each side, one of which is configured to be sliding. An adjusting base plate 39 is fixed on the side of the locking mechanism, and an adjusting screw 40 passes through the adjusting base plate 39. An adjusting knob 41 is fixed to one end of the adjusting screw 40, and the other end of the adjusting screw 40 is rotatably connected to the locking bottom shell 24. Specifically, a circular hole is provided on the side wall of the locking bottom shell 24, and a circular groove larger than the diameter of the circular hole is provided in the circular hole. The end of the adjusting screw 40 is provided with an adjusting disk that rotates in the circular groove, so that the locking mechanism does not rotate when the adjusting screw 40 rotates, and the locking mechanism can be pulled or pushed when the adjusting screw 40 moves.

[0078] Furthermore, a front bin 42 is fixed at the front end below the locking bottom cover 38, the interior of the front bin 42 is a cavity, a support 43 is fixed at the front end of the front bin 42, and a straight-line bin opening 44 is provided at the rear end of the front bin 42. An outer cylinder 45 is connected to the upper end of the adjusting column three 36 via a support rod, and a support rod hole for the support rod to pass through is provided at the bottom of the front bin 42. The interior of the outer cylinder 45 is a cavity, and a front column body 46 is slidably installed at the front end of the outer cylinder 45, and the front column body 46 is partially placed inside the outer cylinder 45 and partially placed outside the outer cylinder 45.

[0079] The front body 46 part placed outside the outer cylinder 45: A front column front groove is formed at the front end of the front column 46 , and a front pressure column 48 corresponding to the top column 43 is connected to the front column front groove via a column spring 47 .

[0080] The front body 46 part placed in the outer tube 45: The diameter of the front body 46 portion placed inside the outer cylinder 45 is larger than the diameter of the front body 46 portion placed outside the outer cylinder 45, so that the front column 46 will not separate from the outer cylinder 45 when sliding. A front column rear groove is provided at the rear end of the front column rear groove, and a wedge block 49 is fixed to the upper end.

[0081] A rear column 50 is rotatably mounted in the rear groove of the front column. Part of the rear column 50 is placed inside the outer cylinder 45 and part of it is placed outside the outer cylinder 45.

[0082] The rear cylinder 50 part placed in the outer cylinder 45: An arc-shaped, continuous V-shaped rear cylinder groove 51 is formed on the surface of the rear cylinder 50 , and the wedge block 49 can move in the rear cylinder groove 51 .

[0083] The rear cylinder 50 portion disposed outside the outer cylinder 45: A straight-line clamping plate 52 is fixed to the end of the rear column 50 , and the clamping plate 52 matches the bay opening 44 so that the clamping plate 52 can pass through horizontally.

[0084] Specifically: When the construction platform enters the photovoltaic installation site, it needs to be fixed. First, it prevents the construction platform from moving, and second, it can achieve automatic rise and fall according to the water level. The rise and fall here does not refer to large-scale rise and fall during rainy season and flood season, but the adaptive changes for the daily water level adjustment of the water conservancy management service station.

[0085] Move the construction platform to the installation location of the photovoltaic bracket, lift the push rod 37, and push it forward. The push rod 37 drives the adjustment column 1 31 to slide forward in the slide groove 3 28, and the adjustment column 2 32 slides in the slide groove 1 26. The current column 46 and the card plate 52 enter the front warehouse 42 through the warehouse opening 44 and the support rod hole, and then continue to push forward. The front pressure column 48 is pushed and compressed by the push column 43. After the front pressure column 48 is compressed to the limit, it continues to be pushed. The push column 43 drives the front column 46 and the wedge block 49 to move backward. The wedge block 49 slides in the rear column groove 51 to support the side wall of the rear column groove 51 and rotate. At this time, the card plate rotates 90°, from horizontal to vertical. At this time, the clamping rod 33 is still in the initial open state.

[0086] Then pull the push rod 37 backward, the adjusting column 1 31 slides backward in the slide groove 3 28, and the clamping plate 52 becomes vertically stuck in the slot 44 and cannot be detached, so the adjusting column 36 cannot move backward, and the clamping rod 33 starts to rotate around the adjusting column 36, and the adjusting column 2 32 enters the slide groove 1 26 into the slide groove 2 27 and moves backward, and the clamping rod 33 starts to rotate from the open state to the clamped state, thereby clamping and fixing the photovoltaic bracket.

[0087] On the contrary, when disengaging, continue to push the push rod 37 forward, the adjusting column 1 31 moves forward in the sliding groove 3 28, the adjusting column 2 32 moves forward from the sliding groove 27 to the sliding groove 1 26, the adjusting column 2 32 moves forward and is pushed by the push column 43, the card plate 52 rotates 90°, from vertical to horizontal, and continues to pull backward to disengage from the front warehouse 42 and return to its original position.

[0088] It should be noted that after being pushed forward, the push rod 37 is placed backward through the push rod hole in the locking bottom shell 24 , and in the initial position, the push rod 37 is rotated forward through the push rod hole and placed in the locking shell 24 .

[0089] Since the photovoltaic bracket has been fixed in advance and the distance between the photovoltaic brackets is different in different construction sites, after one locking mechanism is fixed, the other locking mechanism needs to have a certain range of movement to correspond to the position of the photovoltaic bracket. Therefore, turn the adjusting screw 40, pull or push the locking mechanism to move to the appropriate position corresponding to another photovoltaic bracket, and then fix the locking mechanism. At this time, the two locking mechanisms complete the fixation of the construction platform.

[0090] After the construction platform is fixed, if the water level changes, the construction platform will not move because the construction base 3 is fixed by the clamping ring 34, and the buoy base 1 and the operating base 3 are adjusted to float up and down under the action of buoyancy, without manual adjustment.

[0091] It should be noted that the small-scale adaptation here mainly refers to changes of 20-50cm. Changes less than 20cm have little effect on construction, while changes greater than 50cm require manual adjustment. For small-scale water level changes, when the water level drops, the wire rope 13 becomes loose and can be lowered normally. When the water level rises, during construction every day, the locking mechanism of the winch 10 is opened 10-20 minutes in advance, and then it can be put back in place.

[0092] Furthermore, an upper base 53 is fixed at both ends of one side of the construction base 3, and a lower base 54 is fixed on the corresponding side of the operating base 3. A mounting groove is opened between the upper base 53 and the lower base 54, and the mounting groove is semicircular. Notches 56 in opposite directions are opened at the mounting groove. An upper rotating shaft 55 is rotatably installed in the mounting groove of the upper base 53, and a lower rotating shaft 57 is rotatably installed in the mounting groove of the lower base 54. A plurality of telescopic rods 58 that can be extended and retracted are fixed between the upper rotating shaft 55 and the lower rotating shaft 57, wherein a plurality of transmission rollers 59 are rotatably installed between the two middle telescopic rods 58, and the transmission rollers 59 do not fill the space between the telescopic rods 58. A vertical through groove 60 is opened on the outer side of the transmission roller 59 at the end and is placed on the two telescopic rods 58 there. The end of the through groove 60 is semicircular, and the outer side of the two telescopic rods 58 is fixed with a limited position. Rod 61, a limiting groove 62 is formed between the limiting rod 61 and the telescopic rod 58, an L-shaped cargo board 63 is installed between the two through grooves 60 via a rotating shaft, a pull rope 64 is fixed on the cargo board 63, and a worm gear 65 is provided at the end of one of the upper rotating shafts 55 and the lower rotating shaft 57, and a worm 66 is meshed with the worm gear 65, and the worm 66 is coaxially connected with a handle 67, and two movable holes are correspondingly opened on the upper base 53 and the lower base 54, which are called movable hole one and movable hole two, and a telescopic limiting rod is slidably installed in the movable hole, and the telescopic limiting rod is U-shaped as a whole, including a vertical telescopic limiting pull rod, and the telescopic limiting pull rod is placed in the movable hole one, and transverse rods are fixed at both ends of the telescopic limiting pull rod, which can be placed on the surface of the upper base 53 and the lower base 54, and a blocking rod inserted into the movable hole two is fixed at the transverse end, and the blocking rod is used to block the gap 56.

[0093] Furthermore, bearing seats are fixed on the rear sides of the two telescopic rods 58 at both ends, and an upper pull rod 59 is rotatably installed in the bearing seat. The upper pull rod 59 is connected to the lower pull rod 71 via multiple telescopic pull rods 70 that can be telescoped. A clamping groove 72 is fixed on the lower end of the telescopic rod 58 and the side wall of the operating base 2 for clamping the lower pull rod 71.

[0094] More specifically, if Fig.14The figure shows the initial state. Before construction, the materials need to be transported to the construction base 2. Since the materials include many photovoltaic panels, brackets, parts and other equipment, it is heavy and dangerous to transport them directly from the ladder. If they are thrown directly onto the construction base 2, it is easy to cause damage to the photovoltaic panels.

[0095] By rotating the handle 67 on the upper base 53, the worm gear 66 drives the worm wheel 65 to rotate, and the worm wheel 65 drives the upper rotating shaft 55 to rotate. At this time, the telescopic limit rod 68 limits the upper rotating shaft 55, but does not limit the lower rotating shaft 57. The lower rotating shaft 57 rotates around the upper rotating shaft 55 to a certain angle and then rests on the shore. Then, the lower pull rod 71 is taken out from the clamping groove 72 on the telescopic rod 58 and rotated, and the telescopic pull rod 70 is stretched, and then the lower pull rod 71 is clamped in the clamping groove 72 on the side of the operating base 2 to support the telescopic rod 58. The cargo board 63 is slid upward through the through groove 60, and the rotating shaft of the cargo board 63 is placed in the limiting groove 62. Then, the material is placed on the cargo board 63, and the cargo board 63 is pulled by the pull rope 64. The rotating shaft of the cargo board 63 slides in the limiting groove 62, and the bottom of the cargo board 63 slides on the transmission roller 59, which is more labor-saving to pull.

[0096] It should be noted that in this embodiment, there is no fence 8 at this side position, and the telescopic limiting rod 68 and the telescopic pull rod 70 are provided with limiting holes and limiting bolts.

[0097] After the material transportation is completed, the upper pull rod 69 and the lower pull rod 71 are reset, and the upper rotating shaft 55 continues to rotate so that the upper rotating shaft 55 continues to rotate upward to the top of the construction base 2. At this time, the upper rotating shaft 55, the telescopic rod 58, and the lower rotating shaft 57 are used as the fence 8 on this side.

[0098] When the materials need to be placed on the operating base 2 for standby use, first restore the upper rotating shaft 55 and the lower rotating shaft 57 to their original positions, and push the telescopic limit rod 68 upward. At this time, the notch 56 of the upper base 53 is opened, and the notch 56 of the lower base 54 is limited by the telescopic limit rod 68. Turn the handle 67 at the lower base 54, and the upper rotating shaft 55 will start to rotate around the lower rotating shaft 57. When the upper rotating shaft 55 rotates to the shore, it stops. Since the operating base 2 is lower than the construction base 3, the cargo board 63 does not need to be pulled. The materials are placed on the transmission roller 59 or the telescopic rod 58 and slide to the operating base 2.

[0099] In another embodiment, there is no upper pull rod 69 and lower pull rod 71 on the rear side, or the upper pull rod 69 and lower pull rod 71 are not arranged at the transmission roller 59, and limiting grooves 62 are provided on both sides of the telescopic rod 58, and the through groove 60 is connected to the rear limiting groove 62 in the front and rear directions. When the cargo board 63 is needed, the cargo board 63 is slid to the limiting groove 62 on the other side, the direction of the cargo board 63 is rotated, the material is placed on the cargo board 63, and the material is transported to the operating base 2 by the pull rope 64.

[0100] It should be noted that when the height of the construction platform 3 is adjusted, the corresponding telescopic rod 58 is extended and retracted as needed, so that the upper rotating shaft 55 and the lower rotating shaft 57 can be placed in the upper base 53 and the lower base 54 respectively during operation.

[0101] Furthermore, a fence 8 is provided on the operating base 2, and the fence 8 is U-shaped. A limit wheel 79 is installed at the fence 8 via a rotating shaft. A frame 73 is installed between the two limit wheels 79. A step plate 74 is rotatably installed in the middle of the frame 73. A locking pin is provided on the step plate 74. A roller 75 is rotatably installed at the bottom end of the frame 73. A roller 76 is sleeved on the roller 75. Rolling grooves 77 are opened at the outer ends of both sides of the frame 73. The limit wheels 79 are placed in the rolling grooves 77. When the frame 73 rotates, the limit wheels 79 9 and the rolling groove 77 slide relatively, and a connecting shaft 82 is rotatably installed in the middle of the fence 8, one end of the connecting shaft 82 is sleeved with an adjusting worm gear 83, the adjusting worm gear 83 is meshed with an adjusting worm 84, and the adjusting worm 84 is coaxially connected with an adjusting handle 85, and both ends of the connecting shaft 82 are fixedly sleeved with a connecting rod 2 81, the connecting rod 2 81 is hinged with a connecting rod 1 80, and a stabilizing rod is installed at the hinge of the connecting rod 2 81 and the connecting rod 1 80, and the end of the connecting rod 1 80 is rotatably installed with a positioning wheel 79, and the positioning wheel 79 is fixed to one end of the rolling groove 77.

[0102] Initially, the frame 73 and the step plate 74 are used as the fence 8. During the actual construction and installation, since the photovoltaic panels are in an inclined state, they are at different heights when being constructed under the photovoltaic panels. Generally, benches are placed during construction. In this way, the position of the benches needs to be moved all the time and is unstable. Another way is to set up an additional narrow platform under the photovoltaic panels, and the workers leave the construction platform and stand on the narrow platform for construction, which is more dangerous.

[0103] During specific use, the adjusting handle 85 is rotated, the adjusting worm 84 drives the adjusting worm wheel 83 to rotate, the adjusting worm wheel 83 drives the connecting shaft 82 to rotate, the connecting shaft 82 pulls the connecting rod 2 81 to rotate, and the connecting rod 2 81 pulls the connecting rod 1 80 to rotate. Since the positioning wheel 79 is stationary, the limiting wheel 78 slides in the rolling groove 77, so that the frame 73 rotates forward under the action of the roller 76, and then the step plate 74 is opened and locked with a locking pin to become a step platform of different heights, which is helpful for the installation of photovoltaic panels.

[0104] After the production is completed, the present invention needs: 1. Repeated debugging: After the support system, construction platform and ancillary facilities are installed, the lifting system is debugged repeatedly to verify the lifting performance of the lifting system.

[0105] 2. Find out the causes of any problems found and make timely corrections.

[0106] 3. Carry out load test.

[0107] Three days after the adjustable pontoon construction platform was put into construction, our team members confirmed the use of the pontoon construction platform: (1) The adjustable pontoon construction platform can accommodate 6 people and has a load-bearing capacity of ≥2000kg.

[0108] (2) The time required for each lifting or lowering of the adjustable pontoon construction platform is 4 people*0.1h / time.

[0109] Promotion and application of this project After the goal of this QC activity was successfully achieved, this construction platform was widely promoted in this project, and a total of 150 adjustable pontoon construction platforms were manufactured. For example, on August 17, Tianganghu Township was affected by a typhoon, and the water level of Tiangang Lake surged to 14.61m. By August 25, the water level reached a maximum of 15.61m. On September 1, due to the drop in water level, the water level of Tiangang Lake dropped to 14.26m.

[0110] After two large-scale water level changes, this construction platform performed well in dealing with water surface changes, greatly reducing the time and cost of modifying the construction platform due to water level changes. The project department completed the goal of grid-connected power generation on September 30 as scheduled.

[0111] Economic Benefit Analysis According to the original plan, a total of 150 construction platforms were required for this project. On August 17, Tianganghu Township was affected by a typhoon, and the water level of Tiangang Lake surged to 14.61m. The water level reached a maximum of 15.61m on August 25. On September 1, due to the drop in water level, the water level of Tiangang Lake dropped to 14.26m. Based on the above data, the original construction platform erection plan needed to be modified at least twice.

[0112] (1) Original cost of a single construction platform: material cost (17,000 yuan) + labor cost (2,000 yuan) = 19,000 yuan Cost of single-line reconstruction: 4 man-days × 200 yuan / man-day × 2 times + additional material costs after reconstruction (870 yuan) + lifting machinery costs 100 yuan / time × 2 times = 2670 yuan Total: 19,000 yuan + 2,670 yuan = 21,670 yuan (2) Single adjustable pontoon construction platform: material cost (17,100 yuan) + labor cost (2,500 yuan) + lifting system (1,000 yuan) = 20,600 yuan Cost of lifting a single piece: 0.05 working day × 200 yuan / working day = 10 yuan Total: 20600 yuan + 10 yuan = 20610 yuan (3) Cost difference per item: RMB 21,670 - RMB 20,610 = RMB 1,060 Total cost reduction: 1,060 yuan x 150 items = 159,000 yuan.

[0113] After comparison with similar projects of the company, the water photovoltaic adjustable buoy construction platform of this activity has the characteristics of high construction efficiency, low safety risks and obvious economic benefits in engineering construction. A first draft of the "Standardized Manual for Water Photovoltaic Adjustable Floating Construction Platform" was compiled and planned to be promoted within the company.

[0114] The present invention has the following technical effects: 1. The present invention pulls or releases the wire rope through the rotation of the winch, and the wire rope pulls or releases the round tube to drive the construction platform to rise or fall, so as to adjust the height of the construction platform, thereby meeting the requirements of adjusting the height of the construction platform following the change of water level and ensuring that the construction platform can be constructed normally.

[0115] 2. The capstan can be rotated synchronously through the rotating wheel, the second transmission shaft, the reversing bevel gear and the bevel gear, so that the construction base can be raised and lowered smoothly.

[0116] 3. The locking mechanism can easily lock the photovoltaic bracket to achieve adaptive water level adjustment in a small range. It is simple and reliable to operate, firmly fixed, and ensures the stability of the construction platform during construction.

[0117] 4. By flipping the upper and lower rotating shafts of the side wall, it can be used as a fence and also as an auxiliary material transportation tool. Moreover, the materials can be loaded onto the construction platform or the operating platform, ensuring the safety and stability of the materials during loading.

[0118] 5. Through the rotation adjustment of the frame, it can be used as a fence and also as a ladder, so that a platform of different heights can be provided when installing photovoltaic panels, which is convenient for the installation of photovoltaic panels, and is stable and reliable when used, and does not take up space.

[0119] 6. The overall operation of the present invention is simple, the cost is low, it has a good application value, and it is suitable for popularization.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
