[0037] As shown in the background technology, in the prior art, a working platform is provided on the top of the offshore wind power conductor frame. In order to facilitate the operators to board the working platform, a ladder and a ladder platform are generally provided on the side of the offshore wind power conductor frame. However, some sea anglers use the ladder to board the ladder platform to fish, which poses a safety hazard.

[0038] Based on this, the offshore wind power conduit provided in the embodiment of the present application is used to support the wind turbine tower. The offshore wind power conduit is provided with a conduit body and a detection alarm component. The conduit body is provided with a working platform and at least one ladder structure. The ladder structure is arranged along the extension direction of the conduit body, and the ladder structure is connected with the working platform on the top of the conduit body to facilitate the staff to climb onto the working platform through the ladder structure to carry out equipment maintenance work. A ladder platform is arranged on the ladder structure to improve the safety of the ladder structure. The detection alarm component includes a sensor, a controller and a warning component. Both the sensor and the warning component are connected to the controller for communication, and both the sensor and the warning component are arranged on the ladder platform. When the sea angler climbs onto the ladder platform, the sensor detects that there is someone on the ladder platform, and the sensor transmits the signal to the controller, and the controller controls the warning component to issue an alarm prompt, thereby improving safety.

[0039] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of them. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the embodiments of the present application, and cannot be understood as limitations on the embodiments of the present application. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the embodiments of the present application.

[0040] Figure 1 A schematic diagram of the structure of an offshore wind power conductor frame provided in an embodiment of the present application; Figure 2 for Figure 1 A schematic diagram of the structure of part A in the middle; Figure 3 for Figure 1 Schematic diagram of the structure of the offshore wind turbine duct and wind turbine tower in the middle.

[0041] Reference Figures 1 to 3 As shown, the offshore wind power conduit provided in the embodiment of the present application is used to support a wind turbine tower 10. The offshore wind power conduit includes a conduit body 100 and a detection alarm assembly 200. A working platform 110 and at least one ladder structure 120 are arranged on the conduit body 100. The working platform 110 is arranged on the top of the conduit body 100.

[0042] The ladder structure 120 is disposed along the extension direction of the jacket body 100 . The ladder structure 120 is connected to the working platform 110 . A ladder platform 130 is disposed on the ladder structure 120 .

[0043] The detection alarm component 200 includes a sensor 210, a controller 220 and a warning member 230. The sensor 210 and the warning member 230 are both connected to the controller 220 for communication. The sensor 210 and the warning member 230 are both arranged on the ladder platform 130. The sensor 210 is used to detect whether there is someone on the ladder platform 130. When there is someone on the ladder platform 130, the controller 220 controls the warning member 230 to issue an alarm prompt.

[0044] It is understandable that the work platform 110 is provided on the top of the jacket body 100 to provide a safe working area for the staff for daily maintenance and repair of the wind power equipment. The work platform 110 can also be used to place various instruments and auxiliary equipment, such as meteorological instruments, navigation lights and communication equipment, etc., to support the normal operation of the wind farm. The work platform 110 can also be used to temporarily store tools, parts and other materials for easy transportation and use.

[0045] The extension direction of the ladder structure 120 is consistent with the extension direction of the jacket body 100. The ladder structure 120 is connected to the work platform 110 on the top of the jacket body 100, so that the ladder structure 120 connects the sea surface and the work platform 110, so that the staff can climb from the sea surface or the ship to the work platform 110 through the ladder structure 120, so as to facilitate the staff to carry out equipment maintenance work. In emergencies (such as fire, equipment failure or bad weather), the ladder structure 120 can also be used as an emergency escape route to ensure that the staff can quickly evacuate to a safe area. Thus, the ladder structure 120 can provide a safe and convenient passage for the staff to carry out daily maintenance, overhaul and escape in emergency situations. By reasonably setting the ladder structure 120, the functionality and safety of the offshore wind power jacket can be improved, and the operating efficiency and reliability of the wind farm can be improved.

[0046] Exemplarily, one or more ladder structures 120 may be provided, and the number of ladder structures 120 may be determined according to the structure of the jacket body 100 and the requirements of the wind farm, and the embodiment of the present application does not impose too many restrictions on this.

[0047] The ladder structure 120 is provided with a ladder platform 130 , which can not only provide a resting point for workers when climbing the ladder structure 120 , but also prevent falls to a certain extent, reduce the possibility of injury, and further improve the safety of the ladder structure 120 .

[0048] It should be noted that the power supply required by the detection alarm component 200 can be provided by the wind turbine self-power system, and the sensor 210 and the warning component 230 can be connected to the controller 220 through cables and communication cables. In order to avoid the erosion of high salt fog at sea and the impact of rain on the equipment, the protection level of the sensor 210 and the warning component 230 should not be lower than IP56, and the cables and communication cables should be protected by seawater corrosion-resistant protective pipes to improve the reliability and durability of the detection alarm component 200.

[0049] It should also be noted that high salt fog at sea refers to the tiny salt particles or salt fog formed in the marine environment when the salt in seawater is brought into the air due to natural factors such as waves and wind.

[0050] The controller 220 is used to receive the signal from the sensor 210 and control the warning element 230 to send out an alarm message. In specific implementation, the controller 220 can be set at the bottom of the wind turbine tower 10, which can prevent the controller 220 from being affected by seawater on the one hand and facilitate the staff to repair the controller 220 on the other hand.

[0051] Specifically, by setting up the sensing element 210, it is possible to detect in real time whether there is anyone on the ladder platform 130. When the sea angler climbs onto the ladder platform 130, the sensing element 210 detects that there is someone on the ladder platform 130. The sensing element 210 transmits a signal to the controller 220. The controller 220 controls the warning element 230 to issue an alarm to remind the sea angler to pay attention to safety, thereby improving safety.

[0052] In some embodiments, reference Figure 2 As shown, the sensing element 210 is an infrared sensor or an ultrasonic sensor.

[0053] It should be noted that the infrared sensor determines the presence of the human body by detecting infrared radiation, and the ultrasonic sensor measures the distance and presence of the human body by emitting and receiving ultrasonic waves. The sensing element 210 can use an infrared sensor, an ultrasonic sensor, or other sensors, and the embodiments of the present application do not impose too many restrictions on this.

[0054] Infrared sensors usually include an infrared transmitter, an infrared receiver and a signal processing unit. The infrared transmitter is used to emit infrared light beams; the infrared receiver is used to receive the reflected infrared light beams; the signal processing unit is used to analyze the received infrared signals to determine whether there is a human body.

[0055] Infrared sensors can be divided into active infrared sensors and passive infrared sensors according to their working principles. Active infrared sensors can emit infrared beams. When the beams are reflected back by an object and received by a receiver, the sensor detects the presence of the object. Passive infrared sensors do not emit infrared rays, but detect changes in infrared rays in the environment. When a human body enters the detection range of the sensor, the distribution of infrared rays in the environment will change, and the sensor determines the presence of a human body by detecting this change. The embodiments of the present application may use active infrared sensors or passive infrared sensors, and the embodiments of the present application do not impose too many restrictions on this.

[0056] Ultrasonic sensors usually include an ultrasonic transmitter, an ultrasonic receiver, and a signal processing unit. The ultrasonic transmitter is used to transmit ultrasonic pulses; the ultrasonic receiver is used to receive the reflected ultrasonic pulses; the signal processing unit is used to calculate the time required from the transmission to the reception of the ultrasonic pulse, and then calculate the distance of the object.

[0057] The working principle of the ultrasonic sensor is that the ultrasonic transmitter transmits an ultrasonic pulse, the ultrasonic wave propagates in the air, and is reflected back when encountering an object. The ultrasonic receiver receives the reflected ultrasonic pulse, and the signal processing unit calculates the distance of the object based on the time difference between transmission and reception.

[0058] In some embodiments, reference Figure 2 As shown, the warning member 230 is at least one of a warning light and a speaker.

[0059] It can be understood that the warning light provides a visual alarm by emitting light, and the loudspeaker provides an auditory alarm by emitting sound, so as to issue a warning message to sea anglers, thereby improving the safety of the offshore wind power conductor rack.

[0060] In specific implementation, only a warning light may be provided, or only a loudspeaker may be provided, or both a warning light and a loudspeaker may be provided, that is, the two may be used separately or in combination to further improve the effect of the alarm prompt.

[0061] The warning light issues an alarm prompt. For example, the warning light may be illuminated, the warning light may be flashing, or the warning light may change colors. The embodiments of the present application do not impose too many restrictions on this.

[0062] The speaker issues an alarm prompt. For example, the speaker may issue an alarm sound, or the speaker may issue a safety reminder, or the speaker may issue a departure instruction. The embodiments of the present application do not impose too many restrictions on this.

[0063] In some embodiments, reference Figure 1 and Figure 3 As shown, the detection alarm component 200 also includes a display, which is used to be set in the onshore duty room. The display is communicatively connected with the controller 220. When there is someone on the ladder platform 130, the controller 220 controls the display to issue an alarm prompt.

[0064] It should be noted that the controller 220 can communicate with the display in the onshore duty room by using optical cables in existing submarine cables or 5G wireless communication methods to ensure reliable and stable communication and provide real-time feedback on the boarding status of personnel on the ladder platform 130.

[0065] Specifically, when the sea angler climbs onto the ladder platform 130, the controller 220 controls the display to issue an alarm prompt. For example, an alarm screen of "intrusion" may pop up on the display to remind the staff in the duty room that someone has climbed onto the ladder platform 130, and the staff may urge the sea angler to leave as soon as possible.

[0066] In some embodiments, reference Figure 1 and Figure 3 As shown, the detection alarm component 200 also includes a monitor 240 , which is disposed on the working platform 110 or the wind turbine tower 10 .

[0067] It should be noted that the monitor 240 can be set on the working platform 110 or on the wind turbine tower 10, and the embodiment of the present application does not impose too many restrictions on this.

[0068] In a specific implementation, the monitor 240 can be turned to the connecting position between the working platform 110 and the ladder structure 120, that is, the entrance of the working platform 110, to monitor in real time whether anyone has climbed onto the working platform 110 via the ladder structure 120, so as to record it and further improve the reliability of the detection alarm component 200.

[0069] In some embodiments, reference Figure 1 As shown, the ladder structure 120 includes a first ladder 121 , a second ladder 122 and a third ladder 123 which are arranged in sequence, and the first ladder 121 is connected to the working platform 110 .

[0070] The ladder platform 130 includes a first platform 131 and a second platform 132 . The first platform 131 connects the first ladder 121 and the second ladder 122 , and the second platform 132 connects the second ladder 122 and the third ladder 123 .

[0071] It is understandable that the safety and comfort of the ladder structure 120 can be improved by configuring the ladder structure 120 to be a segmented design of the first ladder 121, the second ladder 122, and the third ladder 123. The first platform 131 and the second platform 132 can not only provide a resting point for the staff to recover their strength before continuing to climb, but also prevent falls to a certain extent and reduce the possibility of injury.

[0072] In some embodiments, reference Figure 1 and Figure 2 As shown, the first platform 131 and the second platform 132 are both provided with a sensing element 210 and a warning element 230 .

[0073] Specifically, the first platform 131 and the second platform 132 are both provided with a sensing element 210 and a warning element 230. When the sea anglers climb onto the first platform 131 via the third ladder 123, the second platform 132 and the second ladder 122 in sequence, multiple alarm prompts can be given to the sea anglers, thereby further improving the safety and reliability of the offshore wind turbine conduit.

[0074] In some embodiments, reference Figure 1 and Figure 2 As shown, a first guardrail 133 is provided on the ladder platform 130 , and the first guardrail 133 is arranged around the circumference of the ladder platform 130 .

[0075] It can be understood that the first guardrail 133 is arranged around the ladder platform 130, which can not only prevent people from falling, but also prevent tools, equipment or other objects from falling from the ladder platform 130, thereby protecting the safety of people and equipment and improving safety.

[0076] In some embodiments, reference Figure 1 and Figure 2 As shown, the ladder structure 120 is provided with a second guardrail 124 , and the second guardrail 124 is connected to the ladder structure 120 and together they form a safety passage.

[0077] It can be understood that the second guardrail 124 and the ladder structure 120 together form a safety passage, providing a physical barrier for the ladder structure 120 to prevent climbers from falling from the ladder structure 120 .

[0078] It should be noted that the ladder structure 120 may also be equipped with anti-slip measures to prevent climbers from slipping during the climbing process, thereby reducing the risk of accidents and improving safety.

[0079] In some embodiments, reference Figure 1 As shown, a support member 140 is further provided on the catheter frame body 100 , and the support member 140 is used to connect the ladder platform 130 and the catheter frame body 100 .

[0080] The ladder platform 130 is connected to the jacket body 100 through the support member 140, and the support member 140 provides support for the ladder platform 130 to ensure the reliability and safety of the ladder platform 130. Exemplarily, the support member 140 can be welded to the ladder platform 130 and the jacket body 100, or can be connected in other ways, and the embodiment of the present application does not impose too many restrictions on this.

[0081] It can be understood by those skilled in the art that the offshore wind power conduit provided in the embodiment of the present application is used to support the wind turbine tower 10. The offshore wind power conduit is provided with a conduit body 100 and a detection alarm assembly 200. The conduit body 100 is provided with a work platform 110 and at least one ladder structure 120. The ladder structure 120 is provided along the extension direction of the conduit body 100. The ladder structure 120 is connected with the work platform 110 at the top of the conduit body 100 to facilitate the staff to climb the work platform 110 through the ladder structure 120 to perform equipment maintenance work. A ladder platform 130 is provided on the ladder structure 120 to improve the safety of the ladder structure 120. The detection alarm assembly 200 includes a sensor 210, a controller 220 and a warning member 230. The sensor 210 and the warning member 230 are both connected to the controller 220 for communication. The sensor 210 and the warning member 230 are both provided on the ladder platform 130. When the sea angler climbs onto the ladder platform 130, the sensor 210 detects that there is someone on the ladder platform 130, and the sensor 210 transmits a signal to the controller 220, and the controller 220 controls the warning element 230 to issue an alarm prompt, thereby improving safety.
