Description

Technical Field

[0001] This utility model relates to the field of mud, and in particular to a mud diversion device for the casing of a rock-embedded pile platform on water. Background Technology

[0002] Mud is a semi-colloidal suspension formed by the dispersion and mixing of fine clay particles in water. It has the consistency of an emulsion and is often used in various engineering applications such as grouting, cooling during drilling, and carrying rock cuttings.

[0003] The mud diversion device between the casing and the slurry for underwater rock-embedded pile platforms is a technology specifically designed to optimize the mud circulation system.

[0004] An existing mud diversion device for a rock-embedded pile platform in water has the following shortcomings:

[0005] When constructing cast-in-place piles on a steel platform, the slurry needs to be diverted. The slurry diversion device must continuously and stably transport the generated slurry to designated locations such as transition casings to ensure the environmental friendliness of the construction and the efficiency of slurry circulation. However, existing diversion devices generally lack height adjustment functions, limiting their applicability. When the outlet of the slurry-producing casing is lower than the inlet of the diversion device, the slurry cannot flow into the device by gravity and must be transported by additional power equipment. This not only increases energy consumption and construction costs, but may also lead to slurry transport interruption due to unstable operation of the power system, thereby affecting construction efficiency and diversion effect. Utility Model Content

[0006] This invention allows for flexible adjustment of the height of the guide tube, thereby solving the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a mud diversion device for a casing of a rock-embedded pile platform on water, comprising an adjustment mechanism, wherein a set of connecting mechanisms is fixedly connected to the outer wall of the adjustment mechanism; the adjustment mechanism includes a float plate, a first box body is fixedly connected to the top of the float plate, a first bevel gear and a second bevel gear are movably inserted into the first box body respectively, a rod is inserted through the outer wall of the second bevel gear, a set of locking blocks is fixedly connected to the outer wall of the rod, a screw rod is movably inserted into the inner wall of the first box body, a lifting column is threadedly connected to the outer wall of the screw rod, and a diversion pipe is inserted through the top of the lifting column. Through the above components, the height of the diversion pipe can be flexibly adjusted, and the operation is simple, improving the efficiency of use.

[0008] Preferably, a concrete block is fixedly connected to the bottom of the float, the first bevel gear and the second bevel gear are meshed together, and the bottom end face of the screw is fixedly connected to the top of the first bevel gear. The concrete block can lower the overall center of gravity of the device and reduce the risk of the float swaying or capsizing caused by wind, waves and water flow.

[0009] Preferably, the outer wall of the first box body is provided with insertion holes, and the inner wall of the insertion hole is slidably connected to the outer wall of the insertion rod and the locking block. Through the cooperation of the insertion rod, the locking block and the insertion hole, the movement of the second bevel gear can be restricted, thereby indirectly achieving the fixation of the first bevel gear and the lead screw.

[0010] Preferably, the bottom of each guide pipe is fixedly connected to a guide post, and the top of each float is fixedly connected to a guide rod. The outer wall of the guide rod is slidably connected to the inner wall of the guide post, and the guide rod and the guide post form a vertical guide structure, which can constrain the guide pipe to rise and fall only in the vertical direction, and avoid the guide pipe from horizontally shifting due to gravity or mud impact during the height adjustment process.

[0011] Preferably, the outer wall of the guide pipe is fixedly connected to a flow regulating valve, the outer wall of the flow regulating valve is fixedly connected to a feed pipe, the outer wall of the feed pipe is fixedly connected to a first flange, the outer wall of the guide pipe is fixedly connected to a discharge pipe, and the outer wall of the discharge pipe is fixedly connected to a second flange. The flow regulating valve can flexibly adjust the mud delivery volume according to the drilling mud production rate, avoiding pipe blockage due to excessive mud flow rate or mud accumulation and overflow in the mud production casing due to excessively slow flow rate.

[0012] Preferably, a rotating rod is movably inserted into the inner wall of the guide pipe, and threaded blades are fixedly connected to the outer wall of the rotating rod. A second housing is fixedly connected to the outer wall of the guide pipe, and an inclined plate is fixedly connected to the top of the second housing. A set of dustproof and waterproof netting is fixedly connected to the inner wall of the second housing. A servo motor is fixedly installed on the inner wall of the second housing. A PLC controller and a battery are fixedly installed on the inner wall of the second housing. The output end of the servo motor is fixedly connected to one end of the rotating rod. The servo motor drives the rotating rod to rotate the threaded blades, which can actively push the mud flow. The dustproof and waterproof netting can prevent dust and moisture from entering the second housing during water construction. The PLC controller can control the speed of the servo motor and the opening of the flow regulating valve.

[0013] Preferably, the connecting mechanism includes a connecting plate, a screw threaded to the inner wall of the connecting plate, a threaded cylinder threaded to the outer wall of the screw, a first clamping block fixedly connected to the outer wall of the threaded cylinder, and a second clamping block fixedly connected to the inner wall of the connecting plate. By rotating the screw to drive the threaded cylinder to move, the distance between the first clamping block and the second clamping block can be adjusted, thereby facilitating the user to clamp and fix the floating plate to the components of the water construction platform (such as steel frame or column).

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, by adjusting the bevel gear transmission structure in the mechanism and coordinating the linkage between the screw and the lifting column, the height of the guide pipe can be flexibly adjusted to accurately match the outlet height of different slurry-producing casings in the construction of steel platform cast-in-place piles, so as to facilitate subsequent slurry diversion. This effectively solves the height mismatch problem between the outlet of the slurry-producing casing and the inlet of the device in the construction scenario of steel platform cast-in-place piles. The concrete block set at the bottom of the floating plate helps to lower the overall center of gravity of the device. In the water environment where the steel platform is located, it can significantly reduce the risk of swaying and overturning caused by wind, waves and water flow, and ensure the safety of slurry diversion operation during the construction of steel platform cast-in-place piles. At the same time, the vertical guiding structure formed by the guide rod and the guide column ensures that the guide pipe will not deviate horizontally during the lifting process. In addition, the connecting mechanism can adapt to construction platform components of different sizes (such as steel frames, columns, etc.) on the steel platform by adjusting the spacing between the clamps through the screw, so as to realize the rapid and stable installation of the slurry diversion device and the steel platform, and further improve the efficiency and reliability of the slurry diversion operation of steel platform cast-in-place piles.

[0016] 2. In this utility model, the flow regulating valve equipped on the guide pipe can flexibly adjust the conveying volume according to the slurry production speed, effectively preventing pipe blockage or slurry accumulation and overflow. The servo motor drives the rotating rod to rotate the threaded blades, which can actively push the slurry, further ensuring the smooth conveying process. The dustproof and waterproof net set on the second box can effectively block dust, moisture and rainwater from entering, thereby protecting the internal servo motor, PLC controller and other key components. In addition, the system is also equipped with a battery to cope with the unstable power supply of the water construction platform and ensure the continuous and reliable operation of the equipment.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Please see Figures 1-7This utility model provides a technical solution: a mud diversion device for the casing of a rock-embedded pile platform on water, including an adjustment mechanism 1, a set of connecting mechanisms 2 fixedly connected to the outer wall of the adjustment mechanism 1; the adjustment mechanism 1 includes a float 101, a first box 120 fixedly connected to the top of the float 101, a first bevel gear 123 and a second bevel gear 125 respectively movably inserted into the first box 120, an insertion rod 122 penetrating through the outer wall of the second bevel gear 125, a set of locking blocks 124 fixedly connected to the outer wall of the insertion rod 122, a screw rod 126 movably inserted into the inner wall of the first box 120, a lifting column 119 threadedly connected to the outer wall of the screw rod 126, and a diversion pipe 107 penetrating through the top of the lifting column 119. Through the above components, the height of the diversion pipe 107 can be flexibly adjusted, and the operation is simple, improving the efficiency of use.

[0028] like Figure 2 and Figure 6 As shown, a concrete block 109 is fixedly connected to the bottom of the float 101. The first bevel gear 123 and the second bevel gear 125 are meshed together. The bottom end face of the screw 126 is fixedly connected to the top of the first bevel gear 123. The concrete block 109 can lower the overall center of gravity of the device and reduce the risk of the float 101 swaying or overturning due to wind, waves and water flow impact.

[0029] like Figure 6 As shown, the outer wall of the first box 120 is provided with insertion holes 121. The inner wall of the insertion hole 121 is slidably connected to the outer wall of the insertion rod 122 and the locking block 124. Through the cooperation of the insertion rod 122, the locking block 124 and the insertion hole 121, the movement of the second bevel gear 125 can be restricted, thereby indirectly fixing the first bevel gear 123 and the lead screw 126.

[0030] like Figure 2 As shown, guide posts 103 are fixedly connected to the bottom of each guide pipe 107, and guide rods 102 are fixedly connected to the top of each float plate 101. The outer wall of the guide rod 102 is slidably connected to the inner wall of the guide post 103. The guide rod 102 and the guide post 103 form a vertical guide structure, which can constrain the guide pipe 107 to rise and fall only in the vertical direction, and prevent the guide pipe 107 from horizontally shifting due to gravity or mud impact during the height adjustment process.

[0031] like Figure 2 and Figure 3As shown, a flow regulating valve 106 is fixedly connected to the outer wall of the guide pipe 107, and a feed pipe 105 is fixedly connected to the outer wall of the flow regulating valve 106. A first flange 104 is fixedly connected to the outer wall of the feed pipe 105, and a discharge pipe 114 is fixedly connected to the outer wall of the guide pipe 107. A second flange 115 is fixedly connected to the outer wall of the discharge pipe 114. The flow regulating valve 106 can flexibly adjust the mud delivery volume according to the drilling mud production speed to avoid pipe blockage due to excessive mud flow rate or mud accumulation and overflow in the mud production casing due to excessively slow flow rate.

[0032] like Figure 4 As shown, a rotating rod 110 is movably inserted into the inner wall of the guide pipe 107. A threaded blade 111 is fixedly connected to the outer wall of the rotating rod 110. A second box 113 is fixedly connected to the outer wall of the guide pipe 107. An inclined plate 112 is fixedly connected to the top of the second box 113. A set of dustproof and waterproof netting 108 is fixedly connected to the inner wall of the second box 113. A servo motor 117 is fixedly installed on the inner wall of the second box 113. A PLC controller 116 and a battery 118 are fixedly installed on the inner wall of the second box 113. The output end of the servo motor 117 is fixedly connected to one end of the rotating rod 110. The servo motor 117 drives the rotating rod 110 to rotate the threaded blade 111, which can actively push the mud flow. The dustproof and waterproof netting 108 can prevent dust and moisture from entering the second box 113 during water construction. The PLC controller 116 can control the speed of the servo motor 117 and the opening of the flow regulating valve 106.

[0033] like Figure 7 As shown, the connecting mechanism 2 includes a connecting plate 201. A screw 205 is threadedly connected to the inner wall of the connecting plate 201. A threaded cylinder 204 is threadedly connected to the outer wall of the screw 205. A first clamping block 203 is fixedly connected to the outer wall of the threaded cylinder 204. A second clamping block 202 is fixedly connected to the inner wall of the connecting plate 201. By rotating the screw 205, the threaded cylinder 204 can be moved, and the distance between the first clamping block 203 and the second clamping block 202 can be adjusted, thereby facilitating the user to clamp and fix the floating plate 101 to the components of the water construction platform (such as steel frame or column).

[0034] The operating method and working principle of this device are as follows: First, by rotating the screw 205, the threaded cylinder 204 and the first clamping block 203 on the outer wall are moved, cooperating with the fixed second clamping block 202 to clamp the platform components (such as steel frames or columns), ensuring the overall stability of the device. The device floats on the water surface relying on the float plate 101, and the concrete block 109 at its bottom can lower the overall center of gravity, reducing the swaying caused by wind, waves and water flow. When it is necessary to adjust the height of the guide pipe 107 to match the outlet of the slurry production casing, the second bevel gear 125 is rotated. The first bevel gear 123 meshes with the second bevel gear 125, and the top of the first bevel gear 123 is fixed to the lead screw 126. Therefore, the lead screw 126 rotates together with the first bevel gear 123, thereby driving the lifting column 119 connected to the outer wall threaded to achieve vertical lifting. The guide pipe 107 at the top of the lifting column 119 rises and falls accordingly. During this process, the guide post 103 at the bottom of the guide pipe 107 slides along the guide rod 102 at the top of the float 101 to ensure that the guide pipe 107 only moves vertically and does not deviate. After adjustment, the insertion... Rod 122 and clamp 124 are inserted into the corresponding insertion hole 121 to restrict the movement of the bevel gear, thereby fixing the height of screw 126 and guide pipe 107. This allows the height of guide pipe 107 to be adjusted and fixed to accommodate different slurry-producing casing heights during steel platform cast-in-place pile construction. During the slurry conveying stage, the feed pipe 105 is sealed to the slurry-producing casing via the first flange 104. Slurry enters guide pipe 107 through feed pipe 105. The slurry conveying volume can be controlled by adjusting the flow regulating valve 106 on the outer wall of guide pipe 107 to avoid... To prevent pipe blockage due to excessive flow rate or sludge accumulation inside the casing due to excessively slow flow rate, if the sludge cannot flow naturally, the battery 118 in the second housing 113 powers the servo motor 117, and the PLC controller 116 controls the servo motor 117 to start. Its output drives the rotating rod 110 in the guide pipe 107 and the threaded blades 111 on the outer wall to rotate, actively pushing the sludge towards the discharge pipe 114. Finally, the sludge is transported to the transition casing or subsequent treatment system through the discharge pipe 114 and the second flange 115 on its outer wall.

[0035] The PLC controller 116, servo motor 117, flow regulating valve 106, and battery 118 used in this application are all common conventional equipment on the market and are well known to those skilled in the art. In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. As for their settings, installation, and electrical connection methods, those skilled in the art can debug and operate them according to the corresponding product instruction manuals, so they will not be described in detail here.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
