Abstract

The present invention discloses a wind power tower barrel reinforcement device, which includes an inner cavity mechanism. An outer sleeve mechanism is arranged on the outside of the inner cavity mechanism, and an end frame mechanism and a bottom frame mechanism are respectively arranged at the upper and lower ends of the inner cavity mechanism and the outer sleeve mechanism; the inner cavity mechanism includes a steel plate inner sleeve. The present invention adopts the cooperation of concrete and steel plates to protect the two ends, making them not easily deformed and worn when being bumped, so as to facilitate transportation and installation. This design can be realized in two ways: prefabrication and on-site fabrication. Compared with a single concrete tower barrel, the construction period is shorter. Through the setting of the arc-shaped outer plate, the concrete is protected from wind, sun and rain, thereby increasing the overall service life. At the same time, in this design, the steel plates are used to combine the concrete flowing into the gaps, and the whole is reinforced. It is not easy for the steel plates and the concrete to fall off, and the force is applied as a whole when stressed. Therefore, a greater force is required to cause damage, ensuring the use strength and service life.

Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and specifically to a reinforcement device for a wind power tower barrel. Background Art

[0002] The wind power tower barrel is the tower pole of a wind power generation unit, which mainly plays a supporting role in the wind power generating set and absorbs the vibration of the unit at the same time. The tower barrel includes a concrete tower barrel and a hybrid tower barrel of concrete and steel plates. Among them, the concrete tower barrel has become the preferred tower structure of the wind power generating set due to its characteristics of large stiffness and high load-bearing capacity.

[0003] In the prior art, when the concrete tower barrel is in use, during the transportation process, it is easy to pass through bumpy roads, and the end is easily damaged, resulting in damage to the outer surface. The stability during use will be relatively reduced. Even if it is filled later, it is difficult to reach the original state. Therefore, the concrete tower barrel is mostly cast on site, resulting in an increase in the construction period. Moreover, when the concrete tower barrel is hoisted and installed, the bottom is also easily knocked and damaged, making the installation of the concrete tower barrel relatively difficult.

[0015] Preferably, a method for preparing a wind power tower is also included, comprising the following steps:

[0016] S1. Select steel plates and cut them into sizes required for preparing the inner cavity mechanism, end frame mechanism, and bottom frame mechanism. Select thin steel plates and cut them into shapes required for preparing the steel plate outer casing.

[0017] S2. Bend the steel plates required for preparing the steel plate inner casing, the first inner ring, the outer guard ring, the bottom guard ring, and the second inner ring, and then weld the ends to form the steel plate inner casing, the first inner ring, the outer guard ring, the bottom guard ring, and the second inner ring. Select steel pipes, grind the inner walls to make the inner diameter sizes equal to those of the first through-hole and the second through-hole, and make the first sleeve and the second sleeve. Select steel pipes with an inner diameter equal to the outer diameters of the first steel bar and the second steel bar, and cut the bottom to a suitable angle.

[0018] S3. Use injection molding to produce the arc-shaped outer plate, the first connecting plate, and the support plate. The first connecting plate and the support plate can be injection-molded together, and then connect the first connecting plate to the arc-shaped outer plate.

[0019] S4. Place the first sleeve on the upper end of the first bottom plate so that the first sleeve communicates with the first through-hole. Weld the first sleeve to the first bottom plate one by one. Then place the second connecting plate on the upper end of the first bottom plate and weld it. Align the inner ring surface of the first inner ring with the inner ring surface of the first bottom plate and weld them. Subsequently, cover the upper end of the first end plate on the upper ends of the first sleeve and the second connecting plate, connect the first through-hole with the first sleeve, and weld between the second connecting plate, the first sleeve, the first inner ring, and the first end plate. Then put the outer guard ring on the outside of the second connecting plate and weld the end of the second connecting plate to the outer guard ring.

[0020] S5. Place the outer clamping pipe at the outer edge of the upper end of the second bottom plate, with the upper inclined opening facing the center line direction of the second bottom plate, and weld it. Place the inner clamping pipe in the opposite direction to the outer clamping pipe and arrange them staggeredly, and then weld. Subsequently, place the second sleeve, connect the second sleeve with the second through-hole, and weld. Align the inner ring surface of the second inner ring with the inner ring surface of the second bottom plate, and finally weld. Then cover the second end plate above the second sleeve and make the second through-hole coincide with the second sleeve, and then weld the joint. Subsequently, weld the lower end of the bottom guard ring to the upper end of the second bottom plate, with the outer surfaces coinciding.

[0021] S6. Horizontally place the bottom frame mechanism, lift the steel plate inner casing, align the outer ring surface of the steel plate inner casing with the outer ring surface of the second end plate, and weld the joint. Weld the second reinforcing rib between the upper surface of the first end plate and the inner wall of the steel plate inner casing. Then lift the end frame mechanism, align the outer ring surface of the first bottom plate with the outer ring surface of the steel plate inner casing and weld, and then weld the first reinforcing rib between the lower end of the first bottom plate and the inner wall of the steel plate inner casing.

[0022] S7. Manually insert the first steel bar and the second steel bar into the gap between the second connecting plates inside the end rack mechanism. Workers below adjust the other ends of the first steel bar and the second steel bar, insert the first steel bar and the second steel bar into the inner clamping pipe and the outer clamping pipe respectively, then weld the first steel bar and the second steel bar to the outer protection ring and the first end plate respectively, and then grind and remove the raised parts on the upper end surface of the first end plate.

[0023] S8. Lay the whole flat and weld the second platform and the first platform inside the steel plate inner sleeve.

[0024] S9. Place the whole horizontally, move the arc-shaped outer plate to the edge of the bottom rack mechanism, then insert the end clamping plate at the lower end into the inner ring surface of the bottom protection ring, make the end clamping plate fit with the inner ring surface of the bottom protection ring. The upper part will bend due to gravity and is supported manually. When the upper end of the end clamping plate is bent to be below the outer protection ring, push the outer sleeve mechanism to make the end clamping plate enter the outer protection ring, and at the same time pull the arc-shaped outer plate upward until the support plate fits with the outer surface of the steel plate inner sleeve. Then cover the steel plate outer sleeve on the surface of the arc-shaped outer plate, weld the end joints, and then grind the raised parts until the surface is smooth.

[0025] S10. Inject concrete into the gap between the second connecting plates, and the concrete fills the gap.

[0026] S11. After the concrete solidifies, lay the whole flat, drill through holes between the inside of the steel plate inner sleeve and the concrete, drive expansion bolts into the through holes, install a climbing ladder inside the steel plate inner sleeve, and the climbing ladder is located inside the platform opening. Then spray anti-corrosion paint on the surface of the whole.

[0027] Preferably, in step S10, the height of each injection of concrete is 0.8 - 1.3 m. When injecting each time, the inner wall of the steel plate inner sleeve can be knocked to discharge the air bubbles in the concrete, avoid air pockets, and at the same time make the concrete flat.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. In the present invention, the two ends are protected by the cooperation of concrete and steel plate, and are not easily deformed and worn when being knocked, which is convenient for transportation and installation. This design can be carried out in two ways: prefabrication and on-site fabrication. Compared with a single concrete tower barrel, the construction period is shorter. Through the setting of the arc-shaped outer plate, the concrete is protected from wind, sun and rain, thereby increasing the overall service life. At the same time, this design allows the concrete to flow into the gap through the combination of steel plates, and the whole is reinforced. It is not easy for the steel plate and the concrete to fall off, and the whole bears the force when stressed, so a larger force is required to cause damage, ensuring the use strength and service life.

[0030] 2. In the present invention, the setting of the first steel bar and the second steel bar is used to increase the overall strength, making it not easy to deform, and the concrete is not easy to break. At the same time, through the fixation of both ends of the first steel bar and the second steel bar, and by using the method of concrete pouring, when it is stressed during use, when one end is deformed by stress, it will also apply force to the other end, thereby increasing the strength and making it not easy to topple.

[0031] 3. In the present invention, the setting of the outer clamping pipe, the inner clamping pipe, the second sleeve, the second connecting plate and the first sleeve increases the contact area with the concrete, further increasing the overall strength, making it not easy to be damaged at both ends. When it is stressed and tilted, there will be a tug-of-war between them, reducing the toppling speed, giving people more time to escape, and increasing safety. Through the setting of the through holes, after the concrete is poured, expansion bolts are used to drive into the concrete, and one end of the bolt directly presses against the inner steel plate sleeve, making the inner steel plate sleeve and the concrete not easy to separate.

[0032] 4. In the present invention, through the setting of the first connecting plate and the supporting plate, a trapezoid is formed between the arc-shaped outer plate, the supporting plate and the first connecting plate. The supporting plate contacts the outer surface of the inner steel plate sleeve to ensure the supporting effect on the arc-shaped outer plate. At the same time, after the concrete solidifies after pouring, it can increase the strength between the arc-shaped outer plate, the inner steel plate sleeve and the concrete, making it not easy to deform. Therefore, when gradually pouring concrete, the subsequent concrete pouring volume can be greater than the previous one. In this way, the overall strength can be increased. And through the setting of the arc-shaped outer plate, the use amount of the overall steel can be reduced, the use cost can be reduced, and the overall weight will be reduced, reducing the transportation and installation costs. By setting the outer steel plate sleeve on the outside, after the outer steel plate sleeve is installed, it coincides with the outer surfaces of the outer protective ring and the bottom protective ring, making the whole more flat. At the same time, it can restrain the arc-shaped outer plate and make it not easy to move. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The bottom frame mechanism 4 includes a No. 2 inner ring 47, the upper and lower ends of the No. 2 inner ring 47 are respectively fixedly connected to the No. 2 bottom plate 41 and the No. 2 end plate 45, the interiors of the No. 2 bottom plate 41 and the No. 2 end plate 45 are both provided with No. 2 through holes 46, a No. 2 sleeve 48 is fixedly connected between the No. 2 bottom plate 41 and the No. 2 end plate 45, the No. 2 sleeve 48 is communicated with the No. 2 through hole 46, the outer edge of the upper end of the No. 2 bottom plate 41 is fixedly connected to the bottom guard ring 44, the outer edge of the upper end of the No. 2 end plate 45 is fixedly connected to the lower end of the steel plate inner sleeve 17, and the outer sleeve mechanism 2 It includes an arc-shaped outer plate 22, and the upper and lower ends of the arc-shaped outer plate 22 are in contact with the outer guard ring 33 and the bottom guard ring 44 respectively. When pouring concrete at the construction site, it is necessary to pour concrete at a height of one meter each time. When it is finally injected into the end frame mechanism 3, the whole can be hoisted first, and then concrete is poured in the end frame mechanism 3, and then the next tower tube is docked with it, and the two tower tubes are connected with bolts. This design enables the upper and lower tower tubes to be connected by concrete, and the connection and fixation with bolts makes the integrity stronger and not easy to tip over.

[0054] In the present invention, the two ends are protected by combining concrete and steel plates, which are not easily deformed or worn when bumped, so as to facilitate transportation and installation. The design can be made by prefabrication and on-site production. Compared with a single concrete tower, the construction period is shorter. The concrete is protected from wind and sun by the arrangement of the arc-shaped outer plate 22, thereby increasing the overall service life.

The steel plates and concrete are not easy to fall off, and the stress is applied as a whole, so a large force is required to cause damage, thereby ensuring the strength of use and service life.

[0055] Embodiment 2

[0056] Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown in , , at the outer edge of the upper end of the second bottom plate 41, an outer clamping tube 42 is fixedly connected. Between the outer clamping tube 42 and the second sleeve 48 at the upper end of the second bottom plate 41, an inner clamping tube 43 is fixedly connected. The outer clamping tube 42 and the inner clamping tube 43 are arranged in a staggered manner. The outer clamping tube 42 is designed to be inclined towards the outer edge of the first end plate 32, and the inner clamping tube 43 is designed to be inclined towards the inner edge of the upper end of the outer retaining ring 33. A second steel bar 6 is inserted into the inside of the outer clamping tube 42, and a first steel bar 5 is inserted into the inside of the inner clamping tube 43. During production, the first steel bar 5 and the inner clamping tube 43, and the outer clamping tube 42 and the second steel bar 6 can be further fixed by welding. The upper end of the first steel bar 5 is fixedly connected to the inner surface of the outer retaining ring 33, and the upper end of the second steel bar 6 is fixedly connected to the outer surface of the first end plate 32. Above and below the middle inside the steel plate inner sleeve 17, a first platform 11 and a second platform 15 are respectively fixedly connected. Platform openings 13 are formed in the second platform 15 and the first platform 11. Between the lower end of the first bottom plate 37 and the inner wall of the steel plate inner sleeve 17, a first reinforcing rib 12 is fixedly connected. Between the upper end of the second end plate 45 and the inner wall of the steel plate inner sleeve 17, a second reinforcing rib 14 is fixedly connected. Through holes 16 are formed on the inner surface of the steel plate inner sleeve 17 between the first platform 11 and the second platform 15. At the upper and lower ends of the arc-shaped outer plate 22, end clamping plates 25 are fixedly connected. On both sides of the middle of the inner ring surface of the arc-shaped outer plate 22, first connecting plates 24 are fixedly connected. One end of the first connecting plate 24 is fixedly connected to a support plate 23.

[0057] In the present invention, through the arrangement of the first steel bar 5 and the second steel bar 6, the overall strength is increased, and it is not easy to deform, and the concrete is not easy to be damaged. At the same time, through the fixation of both ends of the first steel bar 5 and the second steel bar 6, and by using the method of concrete pouring, when a force is applied during use, when one end deforms under force, a force will also be applied to the other end, thereby increasing the strength and making it not easy to tilt. Through the arrangement of the outer clamping tube 42, the inner clamping tube 43, the second sleeve 48, the second connecting plate 34 and the first sleeve 36, the contact area with the concrete is increased, so that the overall strength is further increased, and it is not easy to be damaged at both ends. When tilted under force, there will be a pull between them, reducing the tilting speed and giving people more time to escape, increasing safety. Through the arrangement of the through holes 16, after the concrete is poured, expansion bolts are driven into the concrete, and one end of the bolt directly presses the steel plate inner sleeve 17, making it not easy for the steel plate inner sleeve 17 to separate from the concrete;

[0058] Through the setting of the first connecting plate 24 and the supporting plate 23, a trapezoid is formed among the arc-shaped outer plate 22, the supporting plate 23 and the first connecting plate 24. The supporting plate 23 contacts the outer surface of the steel plate inner sleeve 17 to ensure the supporting effect on the arc-shaped outer plate 22. At the same time, after the concrete is poured and solidified, the strength between the arc-shaped outer plate 22, the steel plate inner sleeve 17 and the concrete can be increased, and deformation is not likely to occur. Thus, when the concrete is gradually poured, the subsequent concrete pouring volume can be greater than the previous one. In this way, the overall strength can be increased. And through the setting of the arc-shaped outer plate 22, the usage amount of the overall steel can be reduced, the usage cost can be reduced, and the overall weight will be reduced, reducing the transportation and installation costs. By setting the steel plate outer sleeve 21 on the outside, after the installation of the steel plate outer sleeve 21, it coincides with the outer surfaces of the outer guard ring 33 and the bottom guard ring 44, making the whole more flat. At the same time, the arc-shaped outer plate 22 can be constrained and is not easy to move. And during welding, the arc-shaped outer plate 22 is also likely to be fused with the steel plate due to high temperature, thereby further increasing the connection strength. When the steel plate outer sleeve 21 is installed, glue can be applied to the inner wall to increase the connection strength with the arc-shaped outer plate 22.
