Description

Technical Field

[0001] The utility model relates to the technical field of wind power tower hoisting safety, in particular to a warning cone used on-site for wind power tower hoisting. Background Art

[0002] The wind turbine tower is the tower pole of wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit. After the wind turbine tower is installed with internal parts and the finished product is inspected, it is transported to the hoisting site and hoisted with hoisting equipment. At this time, safety warning measures need to be taken around to prevent people from entering the dangerous construction area.

[0003] There are two common warning methods at present. The first is to set up warning signs, danger icons and other facilities at the hoisting site; the second is to set up safety guardrails at the hoisting site. Among them, the first method can only serve as a reminder. Once someone enters the hoisting site or an accident occurs, the staff cannot quickly find out; the second method is because the site environment is more complex and dangerous during the construction of the wind turbine tower, and the sizes of the entrances and exits of the construction site are different, which makes it difficult for the guardrails to be used at entrances and exits of different sizes. At the same time, the safety guardrails are large in size and not easy to move. They need to be moved manually, which is time-consuming and labor-intensive, and have certain limitations.

[0029] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts that are not described and disclosed in detail in the following embodiments of the present invention should be understood as existing technologies known or should be known to those skilled in the art, such as the materials of the first shell 102, the second shell 103 and the third shell 104, the models and working principles of batteries, solar panels 1013, flexible LED screens 1021, infrared modules 501, light sensors 1041, LED warning lights 105, motors and servos, the models of gears 502 and inner gear rings 5, the models and working principles of the first connecting joint 4 and the second connecting joint, the specific structures of the lifting platform 2 and the fan foundation 3, etc.

[0030] Example 1

[0031] A warning cone for use at a wind turbine tower hoisting site, such as Figure 1-Figure 6 As shown, the main body 1 includes a first shell 102, a second shell 103 and a third shell 104 which are detachably connected from bottom to top. A flexible LED screen 1021 is fixedly arranged on the first shell 102, which can display warning information, such as road closure and detour, or can display guidance information, such as guide arrows; an annular groove 1302 is circumferentially opened inside the second shell 103, and an inner gear ring 5 is rotatably arranged in the annular groove 1302, and a plurality of infrared modules 501 are distributed on the inner gear ring 5. The infrared module 501 can be set as an infrared transmitting module or an infrared receiving module. Between the two warning cones, an infrared transmitting module and an infrared receiving module can cooperate with each other to form an infrared detector, and the infrared detector can detect people or objects entering the lifting site. A motor for driving the inner gear ring 5 to rotate is fixedly installed in the second shell 103, and a gear 502 matching the inner gear ring 5 is fixedly sleeved on the output shaft 503 of the motor. A transparent window is provided on the second shell 103, and infrared rays of the infrared module 501 can be emitted from the transparent window. A light sensor 1041 is fixedly installed on the third shell 104, and the flexible LED screen 1021, the infrared module 501, the light sensor 1041 and the motor are electrically connected to a main control module. How the main control module is electrically connected to the flexible LED screen 1021, the infrared module 501, the light sensor 1041 and the motor, and how to control their operations are all existing technologies in the field and will not be elaborated here.

[0032] A plurality of warning cones are arranged at the hoisting site and the warning cones are regularly distributed and arranged in a straight line or arc around the hoisting site. The infrared module 501 in the second shell 103 can detect moving objects in a certain direction, such as vehicles and pedestrians. The motor driving gear 502 can drive the inner gear ring 5 to rotate during rotation, thereby changing the direction of the infrared transmitting module or the infrared receiving module on the inner gear ring 5. An infrared transmitting module and an infrared receiving module can cooperate with each other to form an infrared detector. By analogy, a structure similar to an electronic fence is formed between the warning cones. Therefore, changing the direction of the infrared module 501 on the inner gear ring 5 can improve the detection effect of the site. In addition to setting a motor for driving, a small servo can be installed at the bottom of the transmitting end and the receiving end of each infrared module 501. The servo is fixedly arranged in the annular groove 1302. The servo can rotate to a fixed angle according to the control of the main control module. The specific control method is the existing technology in this field and will not be described in detail here. Both methods form a structure similar to an electronic fence between the warning cone and another warning cone. At the same time, the third housing 104 is provided with a Beidou positioning module electrically connected to the main control module. The main control module and the mobile phone are connected by wireless communication. The wireless communication connection method can be conventional methods such as Bluetooth, WIFI, and mobile communication. The mobile phone is connected by wireless communication. Figure 1 The communication module is used to represent that the mobile phone can obtain the position information and detection status transmitted from the warning cone; the light sensor 1041 converts the light intensity value into a voltage value. When the warning cone is placed inside the foundation pit, the surrounding foundation pit has a large slope and there is a risk of collapse. When the surrounding environment is abnormal, the light intensity value changes and the information is transmitted to the main control module. The main control module can transmit alarm information to the mobile phone. A voice module can also be set inside the first shell 102. The main control module can control the voice module to start a voice warning. In addition to the light sensor 1041, a 360° laser radar can also be set to determine whether a collapse accident has occurred based on the distance data detected by the laser radar; similarly, if a certain infrared module 501 encounters an obstacle while working, the main control module can transmit alarm information to the mobile phone and can also control the voice module to start a voice warning.
