Description

Technical Field

[0001] This utility model relates to the field of embedded pipe technology, and in particular to a waterproof sealing kit for embedded pipes in wind power foundations. Background Technology

[0002] A wind turbine, also known as a wind power generator, is an electrical device that converts wind energy into mechanical work. This mechanical work drives a rotor to rotate, ultimately outputting alternating current (AC). A wind turbine generally consists of components such as a wind rotor, a generator (including the generator itself), a directional control unit (tail fin), a tower, a speed limiting safety mechanism, and an energy storage device. To secure the wind turbine, a foundation must be laid before assembly and construction to fix the tower. Wind turbine foundations come in three shapes: circular, square, and octagonal. Currently, the circular extended type is the mainstream, as it has a wide range of applicable foundations and mature design and construction technologies.

[0003] Before pouring concrete, wind turbine foundations require pre-embedded pipes to facilitate cable installation. For example, Chinese Patent Publication No. CN113140984B discloses a "Construction Method for Pre-embedded Cable Pipes in Wind Turbine Foundations of Mountain Wind Power Projects." This method changes the laying method from three rows and three columns to two rows and four columns, which effectively reduces the pressure of the lowermost buried pipe on the upper buried pipe and the foundation load. It adopts a two-layer connection method of internal adhesive bonding and external tape sealing to ensure that both sides of the pre-embedded cable pipe are tightly sealed, which can effectively prevent concrete and other debris from entering the buried pipe and avoid the inability to thread the cable. Three rows and five columns of steel reinforcement brackets are used to fix the cable pipe to prevent the pre-embedded cable pipe from floating due to the flow of concrete into the gaps and the lower part of the pre-embedded cable pipe.

[0004] In practical use, because the cable needs to be bent from a horizontal state to a vertical state within the wind turbine foundation to connect with the power generation part of the wind turbine, the cable needs to be guided by a bent pipe when installing the pre-buried pipe. However, the connection between the bent pipe and the straight pipe is prone to water leakage, which affects the service life of the cable. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as easy water seepage at the connection between the bend and the straight pipe, which affects the service life of the cable, and to propose a waterproof sealing kit for the pre-embedded pipe of the wind power foundation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a waterproof sealing kit for pre-embedded pipes in wind power foundations, including two installation pipes and a bend. The bend includes a bending section and connecting sections at both ends of the bending section. The two connecting sections are respectively connected to the two installation pipes. An insert is fixedly installed inside the connecting section. Multiple support frames are installed inside the installation pipe. The outer wall of the support frame abuts against the inner wall of the installation pipe. A threaded sleeve that is threadedly connected to the insert is fixedly installed on the support frame near the connecting section.

[0007] Furthermore, a first sealing ring is fitted onto the plug-in, and one end of the first sealing ring abuts against the mounting tube.

[0008] Furthermore, the insert is provided with a convex ring that mates with the threaded sleeve, and a second sealing ring is provided between the convex ring and the threaded sleeve.

[0009] Furthermore, a third sealing ring is fixedly provided on the support frame near the connection part, and the other end of the third sealing ring abuts against the plug.

[0010] Furthermore, an installation net is fixedly installed on one side of the support frame, and a desiccant is filled between the installation net and the inner wall of the installation tube.

[0011] Furthermore, a positioning component is provided inside the threaded sleeve, and a positioning hole corresponding to the positioning component is provided on the plug-in.

[0012] Furthermore, the positioning component includes a mounting hole formed on the threaded sleeve, a spring is disposed in the mounting hole, and a positioning bead is connected to the other end of the spring.

[0013] The waterproof sealing kit for pre-embedded pipes in wind turbine foundations proposed in this utility model has the following advantages: In this utility model, the bent pipe is connected to the installation pipe by setting a threaded sleeve inside the installation pipe and connecting it to the plug of the bent pipe. At the same time, a first sealing ring is fitted on the plug. When connected, the first sealing ring abuts against both the bent pipe and the installation pipe to form a sealing structure. Secondly, in this utility model, a sealing structure is formed by setting a second sealing ring to abut against the convex ring, and a sealing structure is formed by setting a third sealing ring to abut against the plug, thereby increasing the sealing and waterproof performance of the pre-embedded pipe after connection.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A waterproof sealing kit for pre-embedded pipes in wind power foundations includes two installation pipes 1 and a bend 2. The bend 2 includes a bending portion 21 and connecting portions 22 disposed at both ends of the bending portion 21. The two connecting portions 22 are respectively connected to the two installation pipes 1. An insert 3 is fixedly disposed inside the connecting portion 22. Multiple support frames 4 are disposed inside the installation pipes 1. The outer wall of the support frame 4 abuts against the inner wall of the installation pipe 1. A threaded sleeve 5 that is threadedly connected to the insert 3 is fixedly disposed on the support frame 4 near the connecting portion 22.

[0018] In this utility model, a threaded sleeve 5 is provided inside the installation pipe 1 to connect with the plug 3 of the bend pipe 2, thereby connecting the bend pipe 2 and the installation pipe 1 to form an integral structure. A support frame 4 is provided to support the installation pipe 1, thereby increasing the strength of the installation pipe 1 and preventing deformation and cracks that could lead to water leakage.

[0019] Furthermore, in this embodiment, a first sealing ring 31 is fitted on the plug-in 3. One end of the first sealing ring 31 abuts against the mounting tube 1. After the bend 2 is connected to the mounting tube 1, both ends of the first sealing ring 31 abut against the outer wall of the bend 2 and the outer wall of the mounting tube 1 to form a sealing structure.

[0020] Furthermore, in this embodiment, the plug-in 3 is provided with a convex ring 32 that cooperates with the threaded sleeve 5. A second sealing ring 33 is provided between the convex ring 32 and the threaded sleeve 5. After the plug-in 3 is connected to the threaded sleeve 5, the outer wall of the convex ring 32 will abut against the second sealing ring 33. The second sealing ring 33 is subjected to force and abuts against the outer wall of the threaded sleeve 5, thereby forming a sealing structure to increase waterproofness.

[0021] It should be noted that, in this embodiment, a third sealing ring 34 is fixedly provided on the support frame 4 near the connecting part 22. The other end of the third sealing ring 34 abuts against the plug 3. As the bend 2 is installed, the force applied by the plug 3 to the third sealing ring 34 also increases, and a sealing structure is formed between the third sealing ring 34 and the plug 3, further increasing the waterproof effect.

[0022] Furthermore, in this embodiment, an installation net 41 is fixedly provided on one side of each support frame 4, and multiple support frames 4 are arranged inside the installation tube 1. A desiccant is filled between the installation net 41 and the inner wall of the installation tube 1. The desiccant is preferably a solid tubular desiccant, which is sleeved on the outside of the installation net 41, leaving space for the desiccant to absorb water and expand during filling.

[0023] In detail, the threaded sleeve 5 is provided with a positioning component 6, and the plug-in 3 is provided with a positioning hole 7 corresponding to the positioning component 6. The positioning component 6 and the positioning hole 7 cooperate to position the installation angle of the bend 2 and prevent it from deviating from the preset angle during installation.

[0024] More specifically, in this embodiment, the positioning component 6 includes a mounting hole formed on the threaded sleeve 5, a spring 61 is provided in the mounting hole, and the other end of the spring 61 is connected to a positioning bead 62 that cooperates with the positioning hole 7. Less than half of the positioning bead 62 is inserted into the positioning hole 7.

[0025] Working method: During operation, the threaded sleeve 5 is installed inside the installation pipe 1 and connected to the plug 3 of the bend 2 to form an integral structure. The two ends of the first sealing ring 31 simultaneously abut against the outer wall of the bend 2 and the outer wall of the installation pipe 1 to form a sealing structure. The outer wall of the convex ring 32 abuts against the second sealing ring 33. The second sealing ring 33 is subjected to force and abuts against the outer wall of the threaded sleeve 5, thereby forming a sealing structure to increase waterproofness. The third sealing ring 34 and the plug 3 form a sealing structure. The installation angle of the bend 2 is positioned by the cooperation of the positioning component 6 and the positioning hole 7 to prevent deviation from the preset angle during installation.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
