Technical Field
[0001] This utility model relates to the field of protective device technology, specifically a safety protective device for high-altitude operations in wind power generation projects. Background Technology
[0002] Safety protection devices for high-altitude operations in wind power projects are crucial facilities for ensuring the safety of workers on wind turbine towers. These safety protection devices include safety nets, which are typically installed in high-altitude work areas to prevent personnel and materials from falling. They play a vital safety role in wind power projects, effectively reducing the risk of accidents that may occur during high-altitude operations and ensuring the personal safety of workers. Safety nets are generally made of high-strength nylon rope or other high-strength materials. Depending on the environment in which they are used, safety nets can be divided into horizontal nets and vertical nets.
[0003] Existing wind turbine towers are typically designed with a conical structure to ensure stable operation of the wind turbine and reduce wind resistance. However, when performing high-altitude operations, traditional fixed-size safety nets often present significant problems when connected to the wind turbine tower. First, because fixed-size safety nets are difficult to match the shape and size of the conical tower, a large gap exists between the net and the tower, increasing the risk of workers falling and posing a safety hazard to high-altitude operations. Second, if the safety net is forcibly installed on the tower, the rigid adjustment will cause the safety net to become excessively taut, which can easily cause the net material to tear, further reducing the protective effectiveness of the safety net and creating new safety hazards.
[0004] In view of this, the present invention proposes a safety protection device for high-altitude operations in wind power generation projects to solve the above-mentioned technical problems. Utility Model Content
[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a safety protection device for high-altitude operations in wind power generation projects. Firstly, utilizing a sliding and telescopic structure of "arc-shaped rod and ring," the diameter can be flexibly adjusted to adapt to the conical shape of the wind turbine tower, which is "thicker at the bottom and thinner at the top." Unlike traditional fixed-size safety nets that often suffer from excessively large gaps or excessive tightness, this device, through the cooperation of the connecting groove and the ring, ensures a tight fit between the net and the tower surface, and the elastic net deforms synchronously with the frame, avoiding both the risk of falling and preventing the net from tearing. Secondly, mechanical clamping (screw-driven arc-shaped anti-slip pad) combined with anti-slip texture enhances friction, solving the problem of slippage associated with traditional knotted fixings. The rigid frame of the aluminum alloy arc-shaped rod, combined with the elastic buffer of the buffer strip, exhibits significantly better tear resistance than traditional nets, greatly reducing the risk of injury during falls. Finally, the inclined design of the deflector plate effectively diverts the impact of strong winds, and, combined with the hollow structure of the elastic net, reduces the swaying of the net in strong winds, preventing the fixing structure from loosening.
[0006] This utility model provides the following technical solution: a safety protection device for high-altitude operations in wind power generation projects, including an adjustable ring frame;
[0007] The annular adjustable frame includes four arc-shaped rods, each of which has a connecting groove extending along its length on one side. The four arc-shaped rods slide in conjunction with the same ring through the connecting grooves, and the width of the ring is half the width of the connecting groove.
[0008] One end of the arc-shaped rod is provided with a limiting structure to restrict its extension and retraction position;
[0009] The other end of the arc-shaped rod is provided with a fixing structure for fixing to the wind turbine tower.
[0010] As a preferred technical solution of this utility model, the limiting structure includes a sliding groove formed at one end of each arc-shaped rod, the sliding groove communicating with the connecting groove, a screw rod passing through the sliding groove, one end of the screw rod being fixedly connected to one end of the ring, a fixing knob being threadedly connected to the surface of the screw rod, and a rubber pad being provided between the fixing knob and the arc-shaped rod.
[0011] As a preferred technical solution of this utility model, the fixing structure includes two mounting plates symmetrically fixed to one end of each arc-shaped rod, a lead screw threaded through the middle of each mounting plate, an arc-shaped anti-slip clamping pad connected to the inner end of the lead screw through a bearing, and a knob fixedly connected to one end of the lead screw.
[0012] As a preferred technical solution of this utility model, each of the arc-shaped rods is provided with a buffer strip on its surface, and the edge of the buffer strip is detachably connected to an elastic mesh surface by a zipper.
[0013] As a preferred technical solution of this utility model, a guide plate is fixedly connected to the top of each arc-shaped rod. The guide plate is arranged along the length direction of the arc-shaped rod and inclined outward. The guide plate is a rubber guide plate.
[0014] As a preferred embodiment of this utility model, both the fixed knob and the surface of the knob are provided with anti-slip textures, and the anti-slip textures are concave structures.
[0015] As a preferred technical solution of this utility model, the arc-shaped anti-slip clamping pad is a rubber arc-shaped anti-slip clamping pad, and the clamping surface of the arc-shaped anti-slip clamping pad is provided with diamond-shaped anti-slip texture.
[0016] As a preferred embodiment of this utility model, each of the arc-shaped rods is an aluminum alloy arc-shaped rod with a rectangular cross-section, and the buffer strip is an elastic webbing buffer strip, which is equidistantly distributed along the circumference of the annular adjustable frame.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. This utility model utilizes the sliding telescopic structure of "arc rod and ring" to flexibly adjust the diameter to adapt to the conical characteristics of wind turbine towers. Unlike traditional fixed-size safety nets that often have excessively large gaps or are too tight, this device, through the cooperation of the connecting groove and the ring, can ensure that the net body is tightly attached to the surface of the tower, and the elastic net surface deforms synchronously with the frame, which not only avoids the risk of falling but also prevents the net body from tearing.
[0019] 2. The mechanical clamping (screw-driven arc-shaped anti-slip pad) of this utility model, combined with anti-slip texture to enhance friction, solves the problem of easy slippage when fixing with traditional rope knots; the rigid frame of the aluminum alloy arc-shaped rod is combined with the elastic buffer of the buffer belt, and the tear resistance is significantly better than that of traditional nets, greatly reducing the risk of injury to the human body when falling.
[0020] 3. The inclined design of the guide plate of this utility model can effectively divert the impact of strong winds. Combined with the hollow structure of the elastic mesh, it reduces the swaying of the mesh in strong wind environment and prevents the fixing structure from loosening. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-4As shown, a safety protection device for high-altitude operations in wind power generation projects includes a ring-shaped adjustable frame;
[0028] The ring-shaped adjustable frame includes four arc-shaped rods 1. Each arc-shaped rod 1 has a connecting groove 101 extending along its length on one side. The four arc-shaped rods 1 slide in contact with the same ring 102 through the connecting groove 101. The width of the ring 102 is half the width of the connecting groove 101.
[0029] One end of the arc-shaped rod 1 is provided with a limiting structure to restrict its extension and retraction position;
[0030] The other end of the arc-shaped rod 1 is provided with a fixing structure for fixing to the wind turbine tower;
[0031] The limiting structure includes a sliding groove 2 opened at one end of each arc-shaped rod 1. The sliding groove 2 is connected to the connecting groove 101. A screw 201 is inserted in the sliding groove 2. One end of the screw 201 is fixedly connected to one end of the ring 102. A fixing knob 202 is threadedly connected to the surface of the screw 201. A rubber pad 203 is provided between the fixing knob 202 and the arc-shaped rod 1.
[0032] The fixing structure includes two mounting plates 3 symmetrically fixed to one end of each arc-shaped rod 1. A lead screw 301 is threaded through the middle of each mounting plate 3. An arc-shaped anti-slip clamping pad 302 is connected to the inner end of the lead screw 301 through a bearing. A knob 303 is fixedly connected to one end of the lead screw 301.
[0033] Each arc rod 1 has a buffer strip 4 on its surface, and the edge of the buffer strip 4 is detachably connected to an elastic mesh 401 via a zipper.
[0034] Each arc-shaped rod 1 is fixedly connected to a guide plate 5 at its top. The guide plate 5 is set along the length of the arc-shaped rod 1 and is inclined outward. The guide plate 5 is a rubber guide plate.
[0035] Both the fixed knob 202 and the knob 303 have anti-slip textures on their surfaces, and the anti-slip textures are concave in structure;
[0036] The arc-shaped anti-slip clamping pad 302 is a rubber arc-shaped anti-slip clamping pad, and the clamping surface of the arc-shaped anti-slip clamping pad 302 is provided with diamond-shaped anti-slip texture;
[0037] Each arc-shaped rod 1 is an aluminum alloy arc-shaped rod with a rectangular cross-section. The buffer strip 4 is an elastic webbing buffer strip, which is equidistantly distributed along the circumference of the ring-shaped adjustable frame.
[0038] Four arc-shaped rods 1 slide with the ring 102 through the inner connecting groove 101. Since the width of the ring 102 is 1 / 2 of the connecting groove 101, the arc-shaped rods 1 can extend and retract radially along the ring 102, so that the overall frame diameter can be adjusted within a certain range to adapt to wind turbine towers of different diameters. After adjustment, the screw 201 in the sliding groove 2 cooperates with the fixing knob 202. Tightening the knob presses the rubber pad 203, locking the relative position of the arc-shaped rods 1 and the ring 102, ensuring the stability of the frame dimensions.
[0039] The fixing structure at the end of the arc rod 1 is passed through the knob 303 to drive the lead screw 301 to advance the arc anti-slip clamping pad 302. The rubber clamping pad, in conjunction with the diamond anti-slip texture on the surface, closely fits the curved surface of the tower, generating mechanical clamping force to prevent the device from sliding under the action of wind at high altitude.
[0040] The elastic mesh 401 is connected to the buffer strip 4 on the arc rod 1 via a zipper to form a ring-shaped protective barrier. When a fall occurs, the polyester mesh of the elastic mesh 401 initially absorbs the impact force through deformation. At the same time, the buffer strip 4 made of elastic webbing material further stretches and buffers, keeping the impact force within a safe range. The flow plate 5 is tilted 15° outward to guide the airflow along the edge of the mesh, reducing the impact of strong winds on the device and preventing the frame from shaking.
[0041] The concave anti-slip texture on the surfaces of the fixed knobs 202 and 303 increases hand friction, making it easier to operate while wearing gloves at heights; the arc-shaped rod 1 is made of aluminum alloy to reduce the overall weight; the buffer strips 4 are evenly distributed to ensure uniform force on the mesh surface; and the zipper connection design facilitates the quick disassembly and replacement of the elastic mesh surface 401.
