[0002] The wind turbine foundation is the fixed end of the wind turbine generator set and is an important component to ensure the normal power generation of the wind turbine. The wind turbine foundation is usually a reinforced concrete structure. When building the wind turbine foundation, it is necessary to insulate the concrete after pouring to prevent the temperature difference between the inside and outside of the concrete from exceeding the limit and causing cracks. The upper and lower ends of the wind turbine foundation are usually cylindrical structures, and the middle part is usually a frustum structure.

[0003] At present, the common maintenance method is to install insulation materials on the surface of the fan foundation concrete for insulation, or to install insulation pipes, and then transport the insulation medium into the insulation pipes for insulation. However, when setting the insulation pipes and insulation materials, because the surface size of the fan foundation is very large, the positions of the insulation pipes and insulation materials are not easy to fix, and winding the insulation pipes and pasting the insulation materials are very time-consuming and labor-intensive. If the insulation pipes and insulation materials are not fixed well, the insulation pipes cannot be close to the fan foundation concrete, or the insulation material is filled between the fan foundation concrete and the insulation pipes, it will affect the maintenance of the fan foundation concrete.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts that are not described and disclosed in detail in the following embodiments of the present invention should be understood as the existing technologies known or should be known to those skilled in the art, such as the structure of the fan foundation concrete 1, the material of the insulation component 2, the material of the hose 5 and the insulation pipe 6, the connection between the hose 5 and the insulation pipe 6, the connection between the joint 10 and the hose 5, the material, specific structure and model of the support rib 7, the material of the clamp 14, how the mounting ring 13 is fixed to the second part 1202, the selection of insulation materials and how to fill them between the baffle 4 and the insulation pipe 6, etc.

[0023] Example 1

[0024] A wind power equipment foundation concrete insulation template, such as Figure 1-Figure 4As shown, it includes a plurality of insulation components 2 arranged on the fan foundation concrete 1. Since the insulation components 2 need to fit with the surface of the fan foundation concrete 1, the surface of the insulation components 2 is arc-shaped. The insulation components 2 include a base plate 3 and an insulation pipe 6. The back of the base plate 3 fits with the surface of the fan foundation concrete 1. The front of the base plate 3 is provided with a receiving groove, and a baffle 4 for closing the receiving groove is detachably provided on the receiving groove. A plurality of limit members 12 are provided on the surface of the baffle 4 facing the receiving groove, and a limit space is formed between the limit members 12 and the baffle 4. All the limit members 12 are distributed in a matrix. The insulation pipe 6 passes through all the limit spaces in turn to form an S shape and contacts with the base plate 3. The insulation pipe 6 is wound along the limit members 12 distributed in the matrix, and finally wound into an S shape. Because the back of the base plate 3 will fit with the surface of the fan foundation concrete 1, in order to ensure that the insulation pipe 6 can better play a heat preservation effect, the insulation pipe 6 contacts with the base plate 3. The receiving groove is also filled with insulation material, and the insulation material is located between the baffle 4 and the insulation pipe 6, so that the insulation material can insulate the heat of the insulation pipe 6 while avoiding the insulation material affecting the function of the insulation pipe 6, and ultimately damaging the insulation pipe 6 to maintain the fan foundation concrete 1. In order to ensure that the insulation medium is better injected into the insulation pipe 6, a water injection hole for injecting the insulation medium into the insulation pipe 6 is opened on the baffle 4. The insulation medium is a conventional prior art in this field and will not be described in detail here. A lifting ring 8 is fixedly provided on the top of the base plate 3, and a lifting hole for installing the lifting ring 8 is provided on the top of the base plate 3. The lifting ring 8 is fixedly installed in the lifting hole for easy installation and use.

A mounting ring 13 is fixedly sleeved on the second portion 1202, and a clamping ring 14 is fixedly connected to the mounting ring 13. The clamping ring 14 can fix the insulation pipe 6 on the first portion 1201 to ensure that the insulation pipe 6 is close to the fan foundation concrete 1. The clamping ring 14 includes a first half ring 1401 and a second half ring 1403 which are rotatably connected to each other. The first half ring 1401 is provided with a plurality of connecting holes 1402 along its circumference, and the second half ring 1403 is provided with an elastic protrusion 1404. The elastic protrusion 1404 can be inserted into any connecting hole 1402, so that the elastic protrusion 1404 can select a suitable connecting hole 1402 according to the caliber of the insulation pipe 6 and be inserted therein. The elastic protrusion 1404 is fixedly connected to the second half ring 1403, and the material of the elastic protrusion 1404 can be set to rubber.
