Description

Technical Field

[0001] The present invention relates to the field of tower devices and use methods, and in particular to an assembled hollow sandwich steel tube concrete wind power combined tower device and a use method. Background Art

[0002] The wind power combined tower device, namely the wind power tower, is an important component of the wind turbine generator set. As the supporting structure of the entire wind turbine generator set, the wind power tower bears the weight of the nacelle, blades, etc., and can ensure the stable operation of the entire wind turbine generator set.

[0003] However, the existing wind turbine towers are basically composed of concrete and partial steel structures. According to construction requirements, the whole is divided into 4 to 6 sections. The main advantage of the mixed tower structure is that it can be constructed on-site, reducing transportation costs and the overall tower cost. However, the construction period is relatively long, the labor cost is high, the installation cost is high, and the wind turbine tower with this structure swings violently during the windy season, and the risk of accidents is high.

[0004] Therefore, in order to solve the problem that the traditional wind power combined tower swings violently during the strong wind season and has a high risk of accidents, an assembled hollow sandwich steel tube concrete wind power combined tower device and a method of use can be designed. Summary of the invention

[0007] Preferably, both the connecting lower seat and the connecting upper seat are provided with mounting holes with matching opening positions; the connecting lower seat mounting hole and the adjacent connecting upper seat mounting hole are connected by fixing bolts.

[0008] Preferably, both the lower connection seat and the upper connection seat are provided with an avoidance groove A for positioning and engaging the supporting tower unit; both the lower connection seat and the upper connection seat are provided with an avoidance groove B for positioning and engaging the combined tower unit; and the inner side of the avoidance groove B is fixedly connected with an avoidance groove C for positioning and engaging the steel pipe stick.

[0009] Preferably, a heat dissipation hole is provided at the lower end of the positioning tube of the control unit; a motor is installed at the middle end inside the control unit; a threaded rod is installed at the upper end of the motor output shaft; a movable seat with an internal thread is transmission-connected to the outer side of the threaded rod; a telescopic arm is fixedly connected to the outer side of the movable seat; there are four groups of telescopic arms; a clamping block is fixedly connected to the outer side of the telescopic arm; a clamping groove is provided on the upper end of the outer surface of the baffle; and the clamping groove and the clamping block are interlockingly connected.

[0010] Preferably, a mounting groove is provided at the connection between the clamping member B and the clamping member A; a sealing strip is plugged inside the mounting groove.

[0011] The method for using the assembled hollow sandwich steel tube concrete wind power combined tower device includes the assembled hollow sandwich steel tube concrete wind power combined tower device described above, and the steps are as follows:

[0012] Step 1: Prepare accessories. The wind power combined tower adopts an assembled design. The main components are as follows: supporting tower unit, connecting lower seat, ventilation unit, combined tower unit, control unit and connecting upper seat. Transport the above components to the tower construction site for on-site preparation and construction;

[0013] Step 2: Install the connector, fix the wind power combined tower base firmly on the ground, position the connecting lower seat on the wind power combined tower base through the fixing bolts, insert the pre-made combined tower barrel unit into the avoidance groove B of the connecting lower seat, and then pass multiple steel pipe sticks through the clamping parts B at both ends of the combined tower barrel unit. The bottom end of the steel pipe stick needs to be inserted into the avoidance groove C to position it;

[0014] Step 3: Install the main parts, hoist the supporting tower unit, align the clamping parts A at both ends of the supporting tower unit with the clamping parts B at both ends of the combined tower unit and insert them until the supporting tower unit is clamped into the avoidance groove A connected to the lower seat. At the same time, ensure that the steel pipe stick is located inside the steel pipe insertion hole of the clamping part A. Install the supporting tower units on all four sides in sequence, and finally insert the sealing strip into the installation groove at the connection between the clamping part B and the clamping part A to prevent concrete from overflowing during the later concrete pouring;

[0015] Step 4: Concrete pouring and reinforcement. Pour the prepared concrete into the pouring groove B formed between the steel pipe stick and the steel pipe insertion hole and the pouring groove A formed after the clamping piece B is connected with the clamping piece A. This design can increase the connectivity between the supporting tower unit and the combined tower unit after the concrete solidifies, and improve the strength of the entire wind power combined tower. Finally, cover and connect the upper seat and fix it. According to the operations of steps 1 and 4, combine 4 to 6 sections;

[0016] Step 5: Installation of the ventilation unit. After the overall wind turbine tower is built, the control unit is hoisted into the octagonal hollow structure inside the wind turbine tower. The bottom of the control unit needs to be fixed to the ground. Use the telescopic arm of the control unit to insert the card block of the control unit into the card slot of the ventilation unit baffle. In this way, when the wind turbine tower encounters strong winds, the motor can be remotely controlled to drive the threaded rod to run, driving the outer moving seat to rise through the telescopic arm linkage limit sliding slot inner baffle to open the ventilation unit.

[0017] Preferably, the ventilation units of the overall wind power combination tower are symmetrically distributed.

[0018] Preferably, the supporting tower unit, the connecting lower seat, the ventilation unit, the combined tower unit, the control unit and the connecting upper seat are connected by fixing bolts or welding after being positioned.

[0019] Beneficial effects of the present invention:

[0020] Compared with the traditional wind power tower composed of concrete and part of the steel structure constructed on site, the present invention adopts an assembled design, and the various components of the wind power combined tower can be produced in the factory in advance, which is convenient for transportation to the tower construction site. The workload of on-site installation is greatly reduced, the demand for a large number of laborers is reduced, and the labor cost is saved. By supporting the tower unit, connecting the lower seat, combining the tower unit, and connecting the upper seat, a modular assembly method can be used, the difficulty of on-site installation is simplified, the construction efficiency is improved, and the construction period is shortened. After the supporting tower unit is connected with the combined tower unit, it is also necessary to pour concrete on the sandwich steel pipe. After the concrete is poured and solidified, a more compact and stable whole is formed between the various components of the wind power combined tower. This stability helps to resist the effects of external loads such as wind force and deadweight, and ensure the long-term safe operation of the tower. A control unit is installed in the hollow cavity of the tower. The control unit is used together with the ventilation unit to remotely control the opening and closing of the ventilation unit, which helps the tower to remain stable under extreme weather conditions, reduce structural fatigue and damage caused by excessive wind force, and reduce the wind resistance coefficient of the tower.
