[0003] The installation of an offshore single-pile fan is a project involving multiple steps. First, the single pile is transported to a designated location at sea by a special vessel to ensure its stability and integrity during transportation. After arrival, a large crane vessel and a hydraulic pile hammer are used to drive the single pile into the seabed to ensure its stability. Then, the tower barrel is hoisted and accurately docked with the top connector of the single pile. Finally, the fan blades, generator, and control system are installed, and a comprehensive inspection is carried out to ensure the safe and stable operation of the entire fan structure.

[0004] Corrosive biogas is generated by seawater and silt inside the offshore single-pile foundation. These gases not only corrode the equipment inside the tower barrel but also increase the risk of explosion or poisoning due to the presence of toxic and combustible gases. Therefore, a biogas alarm device is required to monitor and control the biogas generated inside the offshore single-pile foundation. However, the biogas alarm device is installed on the tower base in a wall-mounted manner and fixed using expansion bolts. Due to long-term exposure on the offshore tower base, the high humidity and high salt spray environment cause the expansion bolts and fasteners to rust, making disassembly and subsequent maintenance difficult.

[0043] Next, the present utility model will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein.

[0044] Embodiment 1

[0045] Refer to Figure 1 - Figure 4 , which is the first embodiment of the present utility model, provides an installation mechanism. This device includes

[0046] An installation unit 100, including an installation base 101, installation holes 102 provided on the installation base 101, and expansion members 103 provided on the installation holes 102; the installation base 101 is used to fixedly support the entire positioning unit 200 and fastening unit 300. The expansion members 103 are placed in the hole grooves reserved on the tower base, and fastening bolts 505b are passed through the installation holes 102 to fasten the expansion members 103, so that the expansion members 103 are more firmly and stably fixed on the tower base.

[0047] A positioning unit 200, a connection base 201 is provided on the installation base 101, an installation block 202 is provided on the connection base 201, and a positioning assembly 203 is provided on the installation block 202; and, a fastening unit 300, including a fixing plate 301 provided on the installation base 101, and a clamping assembly 302 provided on the fixing plate 301. The positioning assembly 203 is used to fix the installation block 202, and the clamping assembly 302 is used to clamp the installation block 202 to prevent the position of the connection base 201 from shifting due to the impact force caused by seawater hitting the tower base.

[0048] Among them, the clamping assembly 302 includes a positioning post 302a provided on the fixing plate 301, a connection plate 302b provided on the positioning post 302a, and a positioning sleeve 302c provided on the connection plate 302b; a positioning groove 204 is provided on the installation block 202. The fixing plate 301 is used to fixedly support the positioning post 302a and the elastic strip 302d, the connection plate 302b is used to fixedly support the connection plate 302b, and the positioning sleeve 302c slides on the positioning post 302a.

[0049] Among them, the clamping assembly 302 further includes an elastic strip 302d disposed on the fixed plate 301. The elastic strip 302d is disposed between the fixed plate 301 and the connecting plate 302b, and a positioning sphere 302e is disposed on the positioning sleeve 302c. The elastic strip 302d can generate a strong elastic force. When the positioning sphere 302e on the positioning sleeve 302c is stuck in the positioning groove 204, the elastic force generated after the elastic strip 302d is pressed can strongly clamp the mounting block 202.

[0050] During the use process, when the operator installs the mounting block 202 on the connecting plate 302b onto the mounting base 101, the clamping assemblies 302 are arranged on the mounting base 101 in the shape of an isosceles triangle. The three clamping assemblies 302 are respectively disposed at the three vertices of the isosceles triangle. The three vertices of the isosceles triangle can evenly distribute the force from the mounting block 202, reduce local stress concentration, and thus improve the stability and reliability of the overall structure of the connecting plate 302b.

[0051] When the operator installs the mounting block 202 between the two positioning spheres 302e, the mounting block 202 will exert extrusion on the positioning spheres 302e. The positioning sleeve 302c on the connecting plate 302b slides on the positioning post 302a, which will cause extrusion on the elastic strip 302d. The extruded elastic strip 302d will generate a strong reaction force, and the reaction force will be transmitted to the surface of the positioning sphere, thereby clamping the surface of the positioning groove 204 on the surface of the mounting block 202, thus fixing the mounting block 202.

[0052] During the installation process, the operator aligns and places the mounting block 202 between the two positioning spheres 302e. This action not only ensures the accurate positioning of the mounting block 202, but also exerts the necessary pressure on the positioning spheres 302e to form an initial extrusion state. As the positioning sleeve 302c slides along the positioning post 302a, the connecting plate 302b further squeezes the elastic strip 302d, causing the elastic potential energy inside the elastic strip 302d to be released and converted into a strong reaction force. The reaction force generated by the elastic strip 302d is transmitted through the positioning spheres 302e and acts on the surface of the positioning groove 204. Finally, the reaction force acts on the positioning groove 204 on the surface of the mounting block 202, achieving a firm clamping of the mounting block 202.

[0053] This clamping method not only provides sufficient fixing force, but also due to its self-locking characteristic, it can maintain the stable position of the mounting block 202 without additional fasteners. When the staff removes the connecting plate 302b from the clamping assembly 302, they only need to pull the connecting plate 302b forcefully to remove the connecting plate 302b from the mounting base 101. This not only improves the installation and disassembly efficiency, but also simplifies the structure by reducing the use of fasteners, and improves the convenience of disassembling and maintaining the connecting plate 302b from the mounting base 101 in the later stage.

[0054] Embodiment 2

[0055] Refer to Figure 1 - Figure 7 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the positioning assembly 203 includes a limiting hole 203a provided on the mounting block 202, a support column 203b provided on the mounting base 101, a limiting sleeve 203c provided in the limiting hole 203a, and a limiting sphere 203d provided on the support column 203b. The positioning assembly 203 is used to fix the positions of the entire mounting block 202 and the connecting plate 302b, prevent external impact forces from affecting the mounting block 202 and the connecting plate 302b, and prevent the mounting block 202 and the connecting plate 302b from deviating from the control of the clamping assembly 302 due to the impact. These impact forces include, but are not limited to, the impact forces generated by the impact of seawater on the tower base.

[0056] Compared with Embodiment 1, further, a first support base 104 and a second support base 105 are provided on the mounting base 101. The first support base 104 and the second support base 105 are used to fixedly support the cylindrical element, facilitating the installation of the protective shell 107.

[0057] Among them, an elastic sleeve 106 is provided on the expansion member 103, a protective shell 107 is provided on the mounting base 101, and a transparent plate 108 is provided on the protective shell 107. The elastic sleeve 106 is used to increase the friction between the expansion member 103 and the reserved hole groove on the tower base, and increase the stability of the mounting base 101 on the tower base. The protective shell 107 is used to protect the parts on the mounting base 101, reduce the corrosion of the parts by the corrosive medium in the marine environment. The protective shell 107 is installed on the mounting base 101 in a simple way of clamping between blocks and holes, which is convenient for installation and disassembly. Moreover, the protective shell 107 is made of an anti-corrosive and non-sound-insulating material, which will not affect the transmission of sound.

[0058] During use, when the operator installs the installation block 202 between the two positioning spheres 302e, the limiting sphere 203d on the support column 203b will pass through the limiting sleeve 203c in the limiting hole 203a. The limiting sleeve 203c is made of a soft and resistive material. The width of the cross-section of the squeezed limiting sleeve 203c is L1, the width of the cross-section of the support column 203b is L2, and the diameter of the limiting sphere 203d is R. The relationship among L1, L2, and R is that R is greater than L1 and L2 is less than L1. In this way, after the support column 203b and the limiting sphere 203d pass through the limiting sleeve 203c, the limiting sleeve 203c quickly returns to its original state by virtue of its elasticity and resistance, realizing the stable clamping of the support column 203b and the limiting sphere 203d, preventing the installation block 202 from falling off the support column 203b, and increasing the stability of the installation block 202 after installation.

[0059] The remaining structures are the same as those in Embodiment 1.

[0060] Embodiment 3

[0061] Referring to Figure 1 - Figure 10 , which is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that a single-pile fan biogas alarm device further includes

[0062] A monitoring unit 400, including a bottom case 401 disposed on the connection base 201, and a top case 402 disposed on the bottom case 401; and, the bottom case 401 serves as the basic structure of the monitoring unit 400. The bottom case 401 is installed on the connection base 201 to provide stable support and protection for the monitoring unit 400. Cooperating with the bottom case 401, a closed monitoring space is formed to protect the internal monitoring equipment from the external environment. The monitoring unit 400 is used to monitor the biogas in the single-pile fan at all times;

[0063] An alarm unit 500, including a carrier 501 disposed on the bottom case 401, a first connecting pipe 502 disposed on the carrier 501, a second connecting pipe 503 disposed on the carrier 501, a pipe conveying assembly 504 disposed on the first connecting pipe 502, and an alarm assembly 505 disposed on the second connecting pipe 503. The alarm assembly 505 is used to alarm when the detected biogas exceeds the standard, reminding the staff to take precautions. The carrier 501 is installed on the bottom case 401 to support the alarm assembly 505 and the pipe conveying assembly 504, ensuring the overall stability of the alarm system

[0064] Compared with Embodiment 2, further, a sensor 403 is disposed on the bottom case 401, and a sensor housing 404 is disposed on the sensor 403. The sensor 403 is used to sense the concentration of biogas in the single-pile fan, and the sensor housing 404 is used to protect the sensor 403 exposed outside the protective shell 107.

[0065] Among them, the pipeline component 504 includes a first support pipe 504a arranged on the first connecting pipe 502, a pipe joint 504b arranged on the first support pipe 504a, and an installation pipeline 504c arranged on the pipe joint 504b. The alarm component 505 includes a second support pipe 505a arranged on the second connecting pipe 503, and a fastening bolt 505b arranged on the second support pipe 505a. The alarm component 505 further includes a lamp holder 505c arranged on the fastening bolt 505b, and an alarm lamp 505d arranged on the lamp holder 505c. Through the pipe joint 504b and the installation pipeline 504c, the pipeline component 504 can be connected to other peripheral pipelines to achieve gas transmission and monitoring, ensuring the integrity and effectiveness of the entire monitoring system.

[0066] During use, the bottom case 401 is firmly installed on the connection base 201 and sealed by the top case 402 to form a protective space to ensure the safety and stability of the internal monitoring equipment. The sensor 403 is installed on the bottom case 401, and the sensor housing 404 provides additional protection for the sensor 403 to ensure the monitoring of the biogas concentration inside the single-pile fan.

[0067] The carrier 501 supports the alarm and pipeline components 504 to ensure the stability of the entire monitoring system. The pipeline component 504 is connected to the external pipeline through the first connecting pipe 502 to achieve effective gas transmission and monitoring, while the alarm component 505 passes through the support pipe, fastening bolt 505b, lamp holder 505c and alarm lamp 505d on the second connecting pipe 503. Each device has an independent voice communication function, uses a 220V power supply, is equipped with a battery, and the battery life is more than 7 days. When the biogas content of a certain fan is higher than 1%, the device emits a harsh alarm sound and automatically dials the duty phone at the same time. The setting of the protective shell 107 does not affect the sound transmission.

[0068] In summary, the biogas alarm device for the single-pile fan improves the accuracy and response speed of biogas monitoring inside the single-pile fan, enhances the reliability and durability of the system, and at the same time reduces potential safety risks through timely alarms, providing a safer working environment for the staff.

[0069] The remaining structure is the same as that of Embodiment 2.
