[0024] See also Figure 1-Figure 6 The pontoon-type water survey platform of the present invention includes an operating platform 1, which is made of a rectangular steel plate and provides a drilling and in-situ test space. A main pontoon 2 for providing buoyancy and a crawler system for providing friction for walking on land are arranged at the bottom of the operating platform 1. A secondary pontoon 3 is detachably installed on the outer side of the main pontoon 2. A spiral propulsion device 4 for providing underwater power to the operating platform 1 is installed on the outer side of the secondary pontoon 3. Positioning piles are installed on the secondary pontoon 3. The positioning piles are used to penetrate into the underwater soil to balance the horizontal force on the operating platform 1 when the operating platform 1 floats.

[0025] In existing water operation platforms or shipbuilding and other related fields, pontoons are often used as basic components to provide buoyancy. For example, some simple water construction platforms use multiple pontoons to be spliced ​​and combined to build a stable bearing surface. The screw propulsion device 4 can be composed of an independent supply battery, a drive motor and a propeller of the prior art. Since the screw propulsion device 4 is a detachable device, it needs to be independently powered.

[0026] In some embodiments, a fuel tank 5 and a power source 6 are respectively provided on both sides of one end of the operating platform 1. Specifically, the track system includes a drive shaft 24 rotatably mounted on the main pontoon 2 near one end of the fuel tank 5, a driven shaft 25 rotatably mounted on one end of the main pontoon 2, a walking track 26 is movably sleeved on the main pontoon 2, and the drive shaft 24 and the driven shaft 25 are meshed with the walking track 26 through gears. The operating platform 1 is installed with a control console 27 and a tool soil sample box 28. The outer side of the main pontoon 2 is fixedly connected to the operating platform 1 through a plurality of load-bearing plates 29. The power source 6 is generally a diesel engine, and the output shaft of the diesel engine is transmission-connected to the drive shaft 24 through a transmission structure 33.

[0027] A slide groove 7 is provided on the auxiliary buoy 3; the positioning pile includes a bracket 8 slidably installed in the slide groove 7, a telescopic cylinder 9 is rotatably installed on the bracket 8, the top of the telescopic cylinder 9 is rotatably connected to a limiting sleeve 11 through a bracket 2 10, the bottom end of the limiting sleeve 11 is rotatably connected to a bracket 3 12, the bottom end of the bracket 3 12 is fixedly installed on the open end of the slide groove 7, an L-shaped mounting plate 13 is fixedly installed on one side of the limiting sleeve 11, a driving motor 14 is fixedly installed on the L-shaped mounting plate 13, the output shaft of the driving motor 14 passes through the L-shaped mounting plate 13 and is installed with a driving gear 15, a pile body 18 is slidably nested in the limiting sleeve 11, a plurality of inverted U-shaped rods 19 are fixedly installed on the pile body 18 at equal intervals, the top of the limiting sleeve 11 is provided with a U-shaped limiting opening, and the inverted U-shaped rod 19 can be slidably nested therein. The power source 6 is connected to an output cable 20, and the output cable 20 is connected to the driving motor 14 through a winding device 21, and the winding device 21 is fixedly installed on the auxiliary buoyancy tank 3; the winding device 21 includes a shell 211 fixedly installed on the auxiliary buoyancy tank 3, and a winding frame 212 is fixedly installed in the shell 211. A rotating cylinder 213 is rotatably sleeved on the winding frame 212, and a volute spring 214 is connected between the rotating cylinder 213 and the winding frame 212. The output cable 20 is wound on the rotating cylinder 213, and a guide wheel 215 is also rotatably installed in the shell 211.

[0028] The working principle of the positioning pile is as follows: the power source 6 can also include a battery and a diesel engine or generate electricity synchronously through a diesel engine. The method can refer to the prior art. Then the battery transmits power to the drive motor 14 through the output cable 20. At this time, the telescopic rod 32 installed in the slide groove 7 is first contracted, so that the bracket 8 slides away from the outside of the slide groove 7, and at the same time the telescopic cylinder 9 is extended. At this time, the limit sleeve 11 will rotate to the outside of the slide groove 7 and finally maintain a vertical state. At this time, the extension is equivalent to the hypotenuse of a right triangle. , and the part of the limiting sleeve 11 corresponding to the top of the telescopic cylinder 9 and the top of the bracket three 12 constitutes a right-angled side of this right-angled triangle, and the other right-angled side is the part of the slide slot 7 corresponding to the bottom of the bracket three 12 to the bottom of the telescopic cylinder 9, and at the same time, the driving motor 14 rotates, so that the driving gear 15 fixedly connected to the output shaft of the driving motor 14 also rotates synchronously, so that the driving gear 15 will move the multiple inverted U-shaped rods 19 on the pile body 18, thereby causing the pile body 18 to gradually slide outward, forming a gear rack matching structure.

[0029] The advantage of this method is that the pile body 18 is driven to rotate by the driving gear 15 and then slides linearly. This is a pure mechanical transmission, with higher structural stability and low cost. The inverted U-shaped rod 19 can be directly welded to the pile body 18. The pile body 18 can also be made of conventional steel pipes, and the steel pipes can be lengthened by welding or threading.

[0030] As the limiting sleeve 11 rotates, the output cable 20 used to power the driving motor 14 thereon will also move with it. At this time, the output cable 20 is wound around the rotating cylinder 213 through the spiral spring 214. At this time, the output cable 20 can be divided into two parts through the splitter, and then the two parts are staggered up and down and wound around the rotating cylinder 213, and then the outlet position is controlled by the guide wheel 215. The function of this part of the device is to release or recycle a certain length of the output cable 20 as needed, so as to avoid winding when the pile body 18 rotates. The cooperation of the two can achieve stable release of the pile body 18.

[0031] In some embodiments of the present invention, the main pontoon 2 is provided with a pair of central transverse axes 22 connected therebetween, and the operating platform 1 is fixedly connected to the central transverse axis 22 via a plurality of platform columns 23 .

[0032] The two parallel main pontoons 2 here are similar to the basic buoyancy structure, and the central horizontal axis 22 and the platform columns 23 are set to support the activity area above. Finally, multiple platform columns 23 are fixedly connected to the operating platform 7 to form a working plane for personnel to operate and place equipment, which has a stronger load-bearing capacity than the existing technology.

[0033] In some embodiments, a platform ladder 30 is movably installed at the rear end of the operating platform 1 .

[0034] It is a common practice to install movable ladders on various structures such as work platforms and ship decks with a certain height. For example, on the edge of the deck of some offshore drilling platforms and large cargo ships, in order to facilitate personnel to go up and down, a ladder that can be folded or lowered is used, which not only meets the passage needs when in use, but also avoids occupying space or causing safety hazards when not needed. Therefore, the platform ladder 30 at the tail end of the operating platform 1 uses this kind of existing mature design concept. Therefore, the specific driving structure of the platform ladder 30 can select any one of the existing technologies.

[0035] In some embodiments, fences 31 are fixedly installed at the front end and both sides of the operating platform 1. Whether it is a high-altitude operating area on water or on land, fences 31 are important facilities to ensure the safety of personnel. For example, high-altitude operating platforms in construction, high-altitude operating areas in industrial plants, and the periphery of various ship decks on the water, fences 31 are fixedly installed to prevent accidental falls of personnel. The fixed installation of fences 31 at the front end and both sides of the operating platform 7 is also based on this existing safety protection idea, and the existing technology of fence 31 installation and fixing is used.

[0036] This floating box type water survey platform is used in conjunction with existing equipment and existing control methods. The specific usage method is as follows: 1) Install and fix at least one of the survey drilling equipment, in-situ testing equipment and engineering measurement equipment on the reserved opening of the operating platform 1.

[0037] 2) The auxiliary pontoon 3, the screw propulsion device 4 and the positioning piles in the pontoon-type water survey platform are defined as accessory parts, and the other structures are defined as the main parts; 3) Operate the control console 27 to drive the floating pontoon water survey platform onto a flatbed transport vehicle or use a crane to lift the floating pontoon water survey platform onto a transport vehicle, transport it to the vicinity of the designated survey site or transport it to the dock for boarding, and drive the floating pontoon water survey platform to the planned survey point; 4) In areas with a water depth of less than 2m, the main body is directly used to carry out the required survey work according to the corresponding drilling sampling specifications or in-situ test specifications. The engineering survey is carried out in accordance with the requirements of the engineering survey specifications. After completing a survey hole position, the floating box-type water survey platform driven by the control console 27 is operated to the next predetermined hole position to continue drilling sampling, in-situ testing or engineering survey work; 5) When the water depth is greater than 2m, a small crane or forklift is used on land to assemble the attachment parts on both sides to the platform body, and then the floating box-type water survey platform driven by the control console 27 is operated to the designated survey point. When the walking crawler 26 floats, the power source 6 provides power, and the walking crawler 26 and the two spiral propulsion devices 4 work simultaneously to provide forward or turning power. After reaching the designated point, the positioning piles are operated to make at least 4 positioning piles stand up and anchor in the soil. When the wind and waves are large, the positioning pile control module needs to be operated to anchor the positioning piles in the soil until the entire platform rises above the water surface. When the wind and waves are small, it is not necessary to raise the operating platform 1 above the water surface. The positioning piles only play an anchoring role. After anchoring, the positioning pile control module is used to level the operating platform 1. The diameter of the positioning pile is generally a steel pipe of more than ten centimeters. For areas with small bearing capacity, a large pile pad can be used at the bottom. The positioning piles are mainly used in water depths exceeding 2-3 meters. At this time, the platform is in a floating state, so it needs to be fixed, which is only a fixing function. For slope areas, positioning piles can play a role in leveling; the necessary survey work is carried out according to the corresponding drilling sampling specifications and in-situ test specifications, and the engineering measurement is carried out according to the requirements of the engineering measurement specifications. After completing a survey hole position, the driving operation platform 1 is controlled to the next predetermined hole position to continue drilling sampling, in-situ testing or engineering measurement work; 6) After the survey of all holes is completed, the floating box water survey platform driven by the operating console 27 is moved to the loading point, the survey instruments and equipment are disassembled, the accessories are disassembled, and the floating box water survey platform is operated to the flatbed transport vehicle, or the operating platform 1 is hoisted to the transport vehicle by a crane for transport back.
