Description

Technical Field

[0001] The utility model relates to a dehumidification device for the tower base of a wind power hybrid tower, belonging to the field of wind power towers. Background Art

[0002] At present, the bottom of the tower barrel 1 of the wind power hybrid tower is made of reinforced concrete and most of them are installed in the farmland on the plain. Since it is very difficult to completely waterproof the concrete structure, during the farmland irrigation or the rainy season, water will slowly penetrate into the tower base from the concrete. The tower base is relatively sealed, and the infiltrated water slowly accumulates at the bottom of the tower, resulting in excessive humidity inside the tower barrel, causing the mechanical components inside the tower barrel to rust and corrode, and the electrical components are extremely likely to be damaged. Content of the Utility Model

[0003] The purpose of the utility model is to provide a dehumidification device for the tower base of a wind power hybrid tower, which can effectively solve the above problems.

[0004] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] It includes a tower barrel, a platform is arranged in the tower barrel, and an installation space is formed by the bottom of the platform, the inner wall of the tower barrel and the bottom of the tower barrel; a rotary dehumidifier is arranged on the platform, the gas input end of the rotary dehumidifier is connected with an air inlet pipe, and the gas output end of the rotary dehumidifier is connected with an air outlet pipe; the air inlet pipe is communicated with a first annular pipe, and the first annular pipe is arranged at the bottom of the tower barrel; the air outlet pipe is communicated with a second annular pipe, and the second annular pipe is arranged at the bottom of the platform; the first annular pipe is evenly distributed with first air pipes, and the first air pipes on the first annular pipe are inclined upwards, the second annular pipe is evenly distributed with second air pipes, and the second air pipes on the second annular pipe are inclined downwards.

[0006] Further: a cross pipe is connected to the middle of the first annular pipe, and ventilation holes are arranged on the cross pipe.

[0007] Further: four connecting pipes are arranged at the lower end of the first annular pipe, the connecting pipes are connected with the ends of the cross pipe, and the cross pipe is located below the floor at the bottom of the tower barrel.

[0008] Further: a breathable net is arranged in the floor above the cross pipe, the cross pipe is composed of a first straight pipe and a second straight pipe, extension pipes are arranged on both sides of the first straight pipe and both sides of the second straight pipe, and the extension pipes are connected to the ventilation holes.

[0009] Further: a pipeline space for installing the cross pipe is arranged at the lower end of the floor.

[0010] Further: a condensate water pipe is also arranged on the rotary dehumidifier, and the pipe orifice of the condensate water pipe is arranged outside the tower barrel.

[0011] Further: The first annular pipe is fixed on the floor through a first snap ring, the second annular pipe is fixed at the bottom of the platform through a second snap ring, and the cross pipe is fixed in the pipeline space through a third snap ring.

[0012] The beneficial effects are as follows:

[0013] Install a high-performance rotary dehumidifier on the platform at the inlet of the tower barrel, and use an air duct to lead the inlet and outlet air of the rotary dehumidifier to the bottom of the tower. When the equipment is working, the air at the bottom of the tower is sucked into the rotary dehumidifier. The dehumidifier will adsorb the moisture in the sucked air on the dehumidifier rotor and then discharge it outside the tower barrel. The dry air coming out is then discharged to the bottom of the tower. By continuously reducing the absolute water content in the air at the bottom of the tower, the evaporation of the water seeping at the bottom of the tower barrel is accelerated, so that the water does not accumulate at the bottom of the tower. In addition, since there is a certain distance between the inlet and outlet of the air duct, when the rotary dehumidification is working, the air at the bottom of the tower flows, which can further accelerate the evaporation rate of the water.

[0023] In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] At the same time, in the description of the present utility model, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] Refer to Figures 1-4 This is an embodiment of the dehumidification device for the wind power hybrid tower foundation of the present utility model.

[0026] It includes a tower barrel 1, a platform 2 is arranged in the tower barrel 1, and the bottom of the platform 2 and the inner wall of the tower barrel 1 and the bottom of the tower barrel 1 form an installation space; electrical equipment required for wind power generation is installed in the installation space; a rotary dehumidifier 3 is arranged on the platform 2, an air inlet pipe 4 is connected to the gas input end of the rotary dehumidifier 3, and an air outlet pipe 5 is connected to the gas output end of the rotary dehumidifier 3.

[0027] The output end of the air inlet pipe 4 is arranged at the lower part inside the installation space, and the output end of the air outlet pipe 5 is arranged at the upper part inside the installation space. When the rotary dehumidifier 3 works, the humid air inside the installation space is sucked away through the air inlet pipe 4 and then converted into dry air, and the dry air is output to the upper part inside the installation space through the air outlet pipe 5; the reason for such a setting is that the density of humid air is greater, so the humid air will gather at the bottom of the installation space.

[0028] In order to further increase the dehumidification efficiency of the installation space, a first annular pipe 6 is communicated with the air inlet pipe 4, and the first annular pipe 6 is arranged at the bottom of the tower barrel 1; and it is arranged at the junction of the tower barrel 1 and the tower bottom. At the same time, first air vent pipes 8 are evenly distributed on the first annular pipe 6, and the first air vent pipes 8 on the first annular pipe 6 are inclined upwards; in this way, the air inside the installation space can be extracted in all directions, and the air extraction efficiency can be greatly improved.

[0029] Meanwhile, in this device, a second annular pipe 7 is connected to the air outlet pipe 5, and the second annular pipe 7 is arranged at the bottom of the platform 2; a plurality of second air vent pipes 9 are evenly distributed on the second annular pipe 7, and the second air vent pipes 9 on the second annular pipe 7 are inclined downward. The second annular pipe 7 is arranged at the junction of the bottom of the platform 2 and the tower barrel 1, and can input dry gas into the installation space in all directions. Cooperating with the air extraction of the first annular pipe 6, the dehumidification efficiency of the installation space is improved.

[0030] A cross pipe 10 is connected to the middle of the first annular pipe 6, and ventilation holes are arranged on the cross pipe 10.

[0031] The purpose of the cross pipe 10 arranged in this device is to fill the blank in the middle of the first annular pipe 6. By using the cross pipe 10 with ventilation holes, the air extraction positions can be further increased, thereby improving the dehumidification efficiency.

[0032] However, considering that the first annular pipe 6 can be arranged at the corner of the tower barrel 1 without affecting the installation of electrical equipment, but the cross pipe 10 will occupy the space on the floor 12, so the cross pipe 10 needs to be hidden.

[0033] Four connecting pipes 11 are arranged at the lower end of the first annular pipe 6, and the connecting pipes 11 are connected to the ends of the cross pipe 10, and the cross pipe 10 is located below the floor 12 at the bottom of the tower barrel 1.

[0034] Through the connecting pipes 11, the horizontal height of the cross pipe 10 can be adjusted to be lower than the floor 12, that is, arranged below the floor 12, and a pipeline space 17 for installing the cross pipe 10 is arranged at the lower end of the floor 12; this will not affect the installation of electrical equipment in the installation space.

[0035] However, since the cross pipe 10 needs to extract the gas in the installation space, a breathable net 13 is arranged in the floor 12 above the cross pipe 10, so that it is convenient for the cross pipe 10 to extract the gas in the installation space;

[0036] At the same time, if the ventilation holes face upward, dust will inevitably directly fall into the cross pipe 10. Therefore, the cross pipe 10 in this device is composed of a first straight pipe 14 and a second straight pipe 15. Extension pipes 16 are arranged on both sides of the first straight pipe 14 and both sides of the second straight pipe 15, and the extension pipes 16 are connected to the ventilation holes; in this way, the extension pipes 16 are horizontally arranged, and dust will not directly fall into the extension pipes 16. At the same time, after a long time, dust will also accumulate in the pipeline space 17. Since the extension pipes 16 do not directly face downward, a large amount of accumulated dust will not be inhaled.

[0037] A condensate water pipe 18 is also arranged on the rotary dehumidifier 3, and the pipe orifice of the condensate water pipe 18 is arranged outside the tower barrel 1. When the rotary dehumidifier 3 is working, condensate water will be generated, and the generated condensate water is directly discharged from the tower barrel 1 through the condensate water pipe 18.

[0038] The first annular pipe 6 is fixed on the floor 12 through the first snap ring, the second annular pipe 7 is fixed at the bottom of the platform 2 through the second snap ring, and the cross pipe 10 is fixed in the pipeline space 17 through the third snap ring. Fixing the annular pipe with a snap ring is a common operation in the field, and the purpose is to facilitate the fixing of the annular pipe.

[0039] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
