Description

Technical Field

[0001] This utility model relates to the field of heat-conducting tube bundle technology, and in particular to a crack-resistant heat-conducting tube bundle structure for wind turbine foundation concrete. Background Technology

[0002] Wind turbine foundations are large-volume concrete structures. The heat of hydration in cement causes a significant increase in internal temperature, and the temperature stress generated by the temperature difference between the inside and outside can easily lead to cracks. Heat-conducting tube bundles, by embedding pipes within the concrete and circulating cooling water or other cooling media through them, utilize the principles of heat conduction and convection to remove heat from the concrete, reducing the peak temperature of the concrete and minimizing the temperature difference between the inside and outside. This effectively inhibits the formation of temperature cracks and ensures the structural performance and durability of the foundation.

[0003] Thermally conductive tube bundles are constructed by pre-embedding thermally conductive pipes, such as steel pipes, thin-walled corrugated iron pipes, or PE pipes, within concrete. Circulating cooling water or other cooling media are then introduced into the pipes. The flow of the media removes heat from the concrete, reducing the peak temperature of the concrete and minimizing the temperature difference between the inside and outside, thereby effectively reducing temperature stress and preventing cracking.

[0004] Impurities and minerals in the cooling medium may deposit inside the pipes, especially when the water quality is poor or there is no effective filtration, which can easily form scale and other deposits that hinder the flow of the medium. Utility Model Content

[0005] The purpose of this invention is to address the problem of silt deposition on riverbanks in the background art by proposing a crack-resistant heat-conducting tube bundle structure for the concrete foundation of wind turbine units.

[0006] The technical solution of this utility model: A crack-resistant heat-conducting tube bundle structure for wind turbine foundation concrete, applied to wind turbine concrete, including a lower heat-conducting tube bundle and an upper heat-conducting tube bundle that are interconnected, the lower heat-conducting tube bundle and the upper heat-conducting tube bundle extending into the interior of the wind turbine concrete, and further including: The filtration mechanism includes a pre-tube fixedly installed between the lower heat-conducting tube bundle and the upper heat-conducting tube bundle, a rear tube fixedly installed at the end of the pre-tube, the end of the rear tube fixedly connected to the upper heat-conducting tube bundle, a vortex generator plate fixedly installed inside the pre-tube, a filter screen fixedly installed inside the rear tube, and a gathering chamber connected to the bottom of the rear tube. Water flows in a spiral motion as it passes through the vortex generator, and the filter screen has a conical structure.

[0007] Optionally, a booster pump is fixedly installed at the connection between the right end of the rear tube and the upper heat-conducting tube bundle. Water flows from the lower heat-conducting tube bundle towards the front and rear tubes, and enters the upper heat-conducting tube bundle to form a circulation.

[0008] Optionally, the length of the rear tube is longer than the length of the front tube, and the gathering chamber is fixedly installed at the bottom of the rear tube and near the right end.

[0009] Optionally, a support frame is fixedly installed inside the rear tube. The support frame has a T-shaped structure, and the end of the support frame is fixedly connected to the filter screen.

[0010] Optionally, a narrow notch is provided at the bottom of the rear tube, and the narrow notch is located near the right end of the filter screen.

[0011] Optionally, the diameter of the pre-heat pipe is larger than the diameter of the lower heat-conducting tube bundle, and the diameter of the pre-heat pipe is the same as the diameter of the rear heat pipe.

[0012] Optionally, the bottom of the gathering chamber is provided with a discharge mechanism, which includes a discharge pipe and is fixedly installed at the bottom of the gathering chamber.

[0013] Optionally, a water valve is fixedly installed on the discharge pipe, and a one-way valve is fixedly installed at the right end of the rear pipe where it connects to the booster pump.

[0015] Optionally, both the lower and upper heat-conducting tube bundles adopt a mosquito coil-like structure, and the bottom of the lower heat-conducting tube bundle is connected to the upper heat-conducting tube bundle.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: 1. This utility model uses a booster pump to draw water, causing it to flow. The water passes through a vortex generator to form a vortex, and then passes through a filter screen to filter out impurities. The impurities in the upper holes of the filter screen are subjected to shearing force from the vortex and are carried out by the water from the holes of the filter screen. They are carried to the right end of the filter screen and then fall into the collection chamber under the action of gravity, thereby filtering the water and cleaning the filter screen to prevent it from becoming clogged and affecting the heat conduction of the lower and upper heat conduction tube bundles.

[0017] 2. This utility model allows impurities in the collection chamber to be discharged from the discharge pipe by opening the water valve, and prevents water in the lower heat conduction tube bundle from entering the pre-pipe and post-pipe by closing the front directional valve. In conjunction with the one-way valve between the upper heat conduction tube bundle and the post-pipe, water is prevented from continuously being discharged from the discharge pipe. Water discharged with impurities is replenished by the replenishment water pipe to prevent impurities from accumulating in the collection chamber and overflowing, thus affecting the flow of water in the post-pipe.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0025] Example: A crack-resistant heat-conducting tube bundle structure for wind turbine foundation concrete, such as... Figure 1 and Figure 2 As shown, the method applied to the concrete 1 of a wind turbine includes a lower heat-conducting tube bundle 2 and an upper heat-conducting tube bundle 3 that are interconnected. The lower heat-conducting tube bundle 2 and the upper heat-conducting tube bundle 3 extend into the interior of the wind turbine concrete 1. Both the lower heat-conducting tube bundle 2 and the upper heat-conducting tube bundle 3 have a mosquito coil-like structure, and the bottom of the lower heat-conducting tube bundle 2 is connected to the upper heat-conducting tube bundle 3. Heat exchange is achieved through the heat-conducting medium flowing within the lower heat-conducting tube bundle 2 and the upper heat-conducting tube bundle 3 to reduce the thermal stress of the concrete.

[0026] like Figures 2 to 5 As shown, a filter mechanism 5 is provided between the lower heat-conducting tube bundle 2 and the upper heat-conducting tube bundle 3. The filter mechanism 5 includes a pre-pipe 51 fixedly installed between the lower heat-conducting tube bundle 2 and the upper heat-conducting tube bundle 3. A rear pipe 52 is fixedly installed at the end of the pre-pipe 51. The diameter of the pre-pipe 51 is larger than the diameter of the lower heat-conducting tube bundle 2, and the diameter of the pre-pipe 51 is the same as the diameter of the rear pipe 52. A vortex generator 54 is fixedly installed inside the pre-pipe 51. A booster pump 4 is fixedly installed at the connection between the right end of the rear pipe 52 and the upper heat-conducting tube bundle 3. Water flows from the lower heat-conducting tube bundle 2 towards the pre-pipe 51 and the rear pipe 52, and enters the upper heat-conducting tube bundle 3 to form a circulating flow.

[0027] The booster pump 4 is powered on to circulate water, which flows from the lower heat-conducting tube bundle 2 towards the front tube 51 and the rear tube 52, and enters the upper heat-conducting tube bundle 3 to form a circulation for heat exchange. The water passes through the vortex generator plate 54 to form vortices.

[0028] A filter screen 55 is fixedly installed inside the post-tube 52. The bottom of the post-tube 52 is connected to a gathering chamber 53. Water is filtered through the filter screen 55 to remove impurities and prevent impurities from clogging the lower heat conduction tube bundle 2 and the upper heat conduction tube bundle 3.

[0029] Since the filter screen 55 filters impurities, there are particles in its holes. The water forming a vortex applies stress to the impurities in the holes of the filter screen 55, so that the impurities in the holes of the filter screen 55 move towards the inner wall of the rear tube 52. The process is the same as the operation process of the drum washing machine. Finally, the impurities are rolled to the collection chamber 53 and sink into the collection chamber 53 under the action of gravity.

[0030] The length of the rear tube 52 is longer than that of the front tube 51. The gathering chamber 53 is fixedly installed at the bottom of the rear tube 52 and near the right end, so that the flow speed of water decreases when it moves to the right end of the rear tube 52, thus preventing the eddy current from carrying out impurities in the gathering chamber 53.

[0031] A support frame 56 is fixedly installed inside the post-tube 52. The support frame 56 has a T-shaped structure, and its end is fixedly connected to the filter screen 55. The filter screen 55 is supported by the support frame 56.

[0032] The bottom of the rear tube 52 has a narrow notch 57, which is located near the right end of the filter screen 55. When the eddy current moves to the position of the narrow notch 57, the rotational force of the eddy current decreases.

[0033] This invention uses a booster pump 4 to draw water, causing it to flow. The water passes through a vortex generator 54 to form a vortex, and then passes through a filter screen 55 to filter out impurities. The impurities in the holes of the filter screen 55 are subjected to shearing force from the vortex and are carried out by the water from the holes of the filter screen 55. They are carried to the right end of the filter screen 55 and, under the action of gravity, are trapped in the collection chamber 53, thereby filtering the water and cleaning the filter screen 55 to prevent it from becoming clogged and affecting the heat conduction of the lower heat conduction tube bundle 2 and the upper heat conduction tube bundle 3.

[0034] like Figure 3 and Figure 4 As shown, a discharge mechanism 6 is provided at the bottom of the collection chamber 53. The discharge mechanism 6 includes a discharge pipe 64, which is fixedly installed at the bottom of the collection chamber 53. A water valve 63 is fixedly installed on the discharge pipe 64. A one-way valve is fixedly installed at the right end of the rear pipe 52, where it connects to the booster pump 4. By opening the water valve 63, impurities precipitated in the collection chamber 53 are discharged through the discharge pipe 64.

[0035] A front directional valve 61 is fixedly installed on the lower heat conduction tube bundle 2 and at the front end of the front tube 51. The top of the front directional valve 61 is connected to a water replenishment pipe 62. Before the impurities are discharged and settled, the front directional valve 61 is closed. At the same time, a check valve is used to prevent water from being discharged in large quantities from the discharge pipe 64. Water discharged with the impurities is replenished through the water replenishment pipe 62.

[0036] This invention allows impurities in the collection chamber 53 to be discharged from the discharge pipe 64 by opening the water valve 63, and closes the front directional valve 61 to prevent water in the lower heat-conducting tube bundle 2 from entering the front pipe 51 and the rear pipe 52. In conjunction with the one-way valve between the upper heat-conducting tube bundle 3 and the rear pipe 52, water is prevented from continuously being discharged from the discharge pipe 64. Water discharged with the impurities is replenished by the water supply pipe 62 to prevent impurities from accumulating in the collection chamber 53 and overflowing, thus affecting the flow of water in the rear pipe 52.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
