Description

Technical Field

[0001] This utility model relates to a safety device, and more particularly to a safety protection device for wind turbine blade assembly, belonging to the field of wind turbine construction technology. Background Technology

[0002] With the continuous development of wind power generation technology, the installation and maintenance of wind turbine generators are becoming increasingly frequent. During the hoisting process of wind turbine generators, the three-blade ground assembly method is a common installation method. This method typically includes steps such as placing the hub, hoisting the blades, and connecting the blades to the hub. During the ground assembly of the rotor, construction workers need to climb onto the blades and walk at height to specific positions to install slings and protective clamps. However, existing construction safety measures are significantly inadequate. Currently, there are no effective safety harness attachment points available when personnel climb onto the blades to operate. This exposes construction workers to high safety risks when walking and working on the blades, increasing the risk of falls. Furthermore, the lack of suitable attachment points makes construction operations on the upper part of the blades extremely inconvenient, affecting work efficiency and potentially increasing safety hazards due to improper operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a safety protection device for wind turbine blade assembly, which can provide reliable attachment points for construction personnel, ensure their safety when walking and working on the blades, and at the same time improve construction efficiency and reduce safety risks.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A safety protection device for assembling wind turbine blades includes a steel pipe, a base plate, and a rubber suction cup. A ring is provided at the top of the steel pipe, and a base plate is provided at the bottom of the steel pipe. Two strap rings are respectively provided on both sides of the base plate, and a strap is provided on each strap ring. A rubber lining is provided at the bottom of the base plate, and a rubber suction cup is provided at the bottom of the rubber lining.

[0006] There are four rubber suction cups, which are evenly distributed on the bottom of the rubber lining. The top of the rubber suction cups is provided with bolts, which are used to fix them together with the rubber lining and the base plate.

[0007] There are four strap loops, and the left and right adjacent strap loops are connected together by a tensioner.

[0008] The strap is made of high-strength polyester rope.

[0009] The thickness of the rubber lining is 5mm, and it is consistent with the size of the base plate.

[0010] The positive and beneficial effects of this utility model are:

[0011] 1. This utility model has a rubber suction cup at the bottom of the rubber lining, and the rubber suction cup is fixedly connected to the rubber lining and the base plate by bolts. This allows the device to be adsorbed onto the blade. With the use of a strap and a tensioner, the device can be firmly connected to the blade. The strap and tensioner are adaptable to wind turbine blades of different shapes and sizes, and have wide applicability. They are convenient to use and easy to operate.

[0012] 2. This utility model features a ring at the top of the steel pipe. When workers walk on the blade, they can attach their safety belts to the ring at the top of the device, providing a reliable connection point for their safety belts. This ensures that workers are always under safety protection when walking and working on the blade, effectively preventing falls and improving their safety. It also enhances the convenience and efficiency of construction operations. Attached Figure Description

[0017] The present invention will be further explained and described below with reference to the accompanying drawings:

[0018] See the example. Figures 1-3 A safety protection device for assembling wind turbine blades includes a steel pipe 1, a base plate 3, and a rubber suction cup 6. A ring 2 is provided at the top of the steel pipe 1, and a base plate 3 is provided at the bottom of the steel pipe 1. Two strap rings 4 are respectively provided on both sides of the base plate 3, and a strap 8 is provided on each strap ring 4. A rubber lining 5 is provided at the bottom of the base plate 3, and a rubber suction cup 6 is provided at the bottom of the rubber lining 5.

[0019] There are four rubber suction cups 6, which are evenly distributed on the bottom of the rubber lining 5. Bolts are provided on the top of the rubber suction cups 6, and they are fixedly connected to the rubber lining 5 and the base plate 3 by means of bolts.

[0020] There are four strap loops 4, and the left and right adjacent strap loops 4 are connected together by a tensioner 9.

[0021] The strap 8 is made of high-strength polyester rope.

[0022] The thickness of the rubber lining 5 is 5mm, and it is the same as the size of the base plate 3.

[0023] In the above description, there are four rubber suction cups arranged in a rectangular shape. During installation, the bolts on the top of the rubber suction cups are passed through the rubber lining and the base plate in sequence, and then fixed with matching nuts.

[0024] In the above description, the steel pipe is 1000mm long. The top section is made of φ8 steel bars, forming a circular ring welded to the top of the steel pipe, which serves as the attachment point for the safety rope buckle. The lower part of the steel pipe is welded to a 200*200*5mm steel plate. The bottom of the steel plate is lined with rubber of the same size and 5mm thickness. The rubber lining and the steel plate can be reliably connected by adhesive or other methods. Four circular rubber suction cups are installed at the bottom of the rubber lining. The circular rubber suction cups can be bolted to the upper steel plate and the rubber lining. Four strap rings are installed on the side of the steel plate, two on each side. The strap rings can be made of φ8 steel bars, with a ring size of 30*20mm, and can be reliably welded to the steel plate. A high-strength polyester strap is passed through the strap rings and secured by a rope tightener.

[0025] In the above description, the size of the lower suction cup can be selected and manufactured according to the on-site device's secure fixation.

[0026] In the above description, the rope tensioner is existing technology, so its structure is not described in detail, but this does not affect the understanding of this solution.

[0027] Working principle:

[0028] In use, four of these safety protection devices are attached to the upper part of a wind turbine blade. The devices are connected by a φ12 plastic-coated steel wire rope passing through the upper ring. Workers attach the device to the blade using a suction cup and pass a high-strength polyester strap through the strap ring. The strap is then tightened using a rope tightener to secure the device firmly to the blade. Workers can also attach the double-rope safety belt buckle to the upper ring of the column or to the steel wire rope to achieve the purpose of safety protection.

[0029] This invention, by setting a rubber suction cup at the bottom of the rubber lining and using a strap and a rope tensioner, can firmly connect the device to the blade. It is easy to assemble and disassemble, can be reused, effectively prevents falling accidents, improves the safety of construction workers walking and working on the blade, enhances the convenience and efficiency of construction operations, avoids scaffolding erection, reduces construction costs, and is easy to promote.
