[Technical field]

[0001] The present invention relates to the technical field of biogas early warning, and in particular to a mounting mechanism and a biogas warning device for a monopile turbine. [Background technology]

[0002] Offshore monopile turbines, a part of the infrastructure for offshore wind power plants, are made up of steel pipe piles that are inserted straight into the seabed and connected to the turbine tower, and pile driving vessels are used to ensure their stability and load-bearing capacity.

[0003] The installation of an offshore monopile turbine is a multi-stage project. First, the monopile is transported by a dedicated vessel to a designated location offshore to ensure stability and integrity during transportation. Upon arrival, the monopile is driven into the seabed using a large lifting vessel and a hydraulic piling hammer to ensure the monopile's stability. Next, the tower is lifted and precisely aligned with the monopile's top connector. Finally, the turbine blades, generator and control system are installed and fully inspected to ensure the safe and stable operation of the entire turbine structure.

[0004] Corrosive biogas generated from seawater and silt inside offshore monopile foundations not only corrodes equipment inside the tower, but also increases the risk of explosion and poisoning due to the presence of toxic and flammable gases, so a biogas alarm device is needed to monitor and control the biogas generated inside the offshore monopile foundation. However, the biogas alarm device is wall-mounted to the tower base and fixed with expansion bolts, and is exposed to the offshore tower base for a long period of time, so the expansion bolts and fixings rust and corrode in the high humidity and salt spray environment, making removal and subsequent maintenance difficult.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] In order to make the above objectives, features and advantages of the present invention clearer and easier to understand, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings of the specification.

[0024] In order to facilitate a thorough understanding of the present invention, numerous specific details are described below; however, the present invention may be embodied in other ways than those described herein, and similar extensions may be made by those skilled in the art without departing from the spirit of the present invention, and therefore the present invention is not limited by the specific embodiments disclosed below.

[0025] Additionally, as used herein, "one embodiment" or "embodiment" refers to a particular feature, structure, or characteristic that may be included in at least one embodiment of the present invention. The appearances of the phrase "in one embodiment" in different places in this specification are not all referring to the same embodiment, nor are they mutually exclusive embodiments separate or in the alternative from other embodiments.

[0026] Furthermore, the present invention will be described in detail in conjunction with schematic drawings, and in describing the embodiments of the present invention in detail, in order to facilitate the description, the cross-sectional view showing the structure of the device will be partially enlarged without being scaled down, and the schematic drawing is merely illustrative and does not limit the scope of protection of the present invention, which should include the three-dimensional spatial dimensions of length, width and depth during actual production.

[0027] Example 1 1 to 4, a first embodiment of the present invention provides a mounting mechanism, which includes a mounting unit 100, a positioning unit 200 and a fastening unit 300. The mounting unit 100 comprises a mounting base 101, a mounting hole 102 provided in the mounting base 101, and an expansion member 103 provided in the mounting hole 102. The mounting base 101 is used to support the positioning unit 200 and the fastening unit 300 as a whole. The expansion member 103 is placed in a pre-drilled hole groove in the tower base and is tightened by passing a fastening bolt 505b through the mounting hole 102, so that the mounting unit 100 is more firmly and stably fixed to the tower base.

[0028] The positioning unit 200 includes a connection base 201 provided on the mounting base 101, a mounting block 202 provided on the connection base 201, and a positioning assembly 203 provided on the mounting block 202, while the fastening unit 300 includes a fixing plate 301 provided on the mounting base 101, and a clamp assembly 302 provided on the fixing plate 301. The positioning assembly 203 is used to fix the mounting block 202, and the clamp assembly 302 is used to clamp the mounting block 202, to prevent seawater from washing up on the tower base and causing an impact force that would displace the position of the connection base 201.

[0029] Here, the clamp assembly 302 includes a positioning post 302a provided on a fixed plate 301, a connecting plate 302b provided on the positioning post 302a, and a positioning sleeve 302c provided on the connecting plate 302b, and the mounting block 202 is provided with a positioning groove 204. The fixed plate 301 is used to fixably support the positioning post 302a and the elastic strip 302d, the connecting plate 302b is used to fixably support the connecting plate 302b, and the positioning sleeve 302c slides on the positioning post 302a.

[0030] Here, the clamp assembly 302 further includes an elastic strip 302d provided on the fixed plate 301, the elastic strip 302d being provided between the fixed plate 301 and the connecting plate 302b, and a positioning ball 302e being provided on the positioning sleeve 302c. The elastic strip 302d can generate a strong elastic force, and when the positioning ball 302e on the positioning sleeve 302c fits into the positioning groove 204, the elastic force generated by pressing the elastic strip 302d can clamp the mounting block 202 strongly.

[0031] In use, when an operator attaches the mounting block 202 on the connection plate 302b to the mounting base 101, the clamp assemblies 302 are arranged in an isosceles triangle shape on the mounting base 101, and the three clamp assemblies 302 are respectively provided at the three vertices of the isosceles triangle, which can evenly distribute the force from the mounting block 202 and reduce the concentration of local stress, thereby improving the stability and reliability of the overall structure of the connection plate 302b.

[0032] When an operator attaches the mounting block 202 to the two positioning balls 302e, the mounting block 202 pushes out the positioning balls 302e, and the positioning sleeve 302c on the connecting plate 302b slides along the positioning pillar 302a, thereby pushing out the elastic strip 302d. After being pushed out, the elastic strip 302d generates a strong reaction force, which is transmitted to the surface of the positioning groove 204 on the surface of the mounting block 202, thereby fixing the mounting block 202.

[0033] When the worker installs the mounting block 202, the mounting block 202 is aligned and positioned between the two positioning balls 302e, which not only ensures the accurate positioning of the mounting block 202, but also applies the necessary pressure to the positioning balls 302e to form an initial extrusion state. When the positioning sleeve 302c slides along the positioning column 302a, the connecting plate 302b further compresses the elastic strip 302d, and the elastic potential energy inside the elastic strip 302d is released and converted into a strong reaction force, and the reaction force generated by the elastic strip 302d is transmitted through the positioning balls 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, so that the mounting block 202 can be firmly clamped.

[0034] Such a clamp not only provides sufficient fixing force, but its self-locking characteristics allow the mounting block 202 to be held in a stable position without additional fasteners, so that when an operator removes the connection plate 302b from the clamp assembly 302, the operator only needs to pull the connection plate 302b to remove it from the mounting base 101. This not only improves the efficiency of installation and removal work, but also simplifies the structure by reducing the use of fasteners, and improves the ease of subsequent removal of the connection plate 302b from the mounting base 101 and maintenance.

[0035] Example 2 1 to 7, the second embodiment of the present invention is different from the first embodiment in that the positioning assembly 203 includes a limit hole 203a provided in the mounting block 202, a support column 203b provided in the mounting base 101, a limit sleeve 203c provided in the limit hole 203a, and a limit ball 203d provided in the support column 203b. The positioning assembly 203 is used to fix the position of the mounting block 202 and the connection plate 302b as a whole, and prevents the mounting block 202 and the connection plate 302b from being displaced out of the control of the clamp assembly 302 due to external impact forces. These impact forces include, but are not limited to, impact forces generated by seawater colliding with the tower base.

[0036] Compared with the first embodiment, the mounting base 101 is further provided with a first support base 104, and the mounting base 101 is provided with a second support base 105. The first support base 104 and the second support base 105 are used to reliably support the cylindrical element and facilitate the installation of the protective shell 107.

[0037] Here, the expansion member 103 is provided with an elastic sleeve 106, the mounting base 101 is provided with a protective shell 107, and the protective shell 107 is provided with a transparent plate 108. The elastic sleeve 106 is used to increase the friction force between the hole groove pre-drilled in the tower base and the expansion member 103, and increase the stability of the mounting base 101 on the tower base. The protective shell 107 is used to protect the components on the mounting base 101 and reduce the corrosion of the components caused by corrosive media in the marine environment, and the protective shell 107 is attached to the mounting base 101 by a simple snap-in manner of blocks and holes, so that it is easy to install and remove, and furthermore, the protective shell 107 is made of a non-acoustic insulating material that is corrosion-resistant and does not affect the propagation of sound.

[0038] During use, when an operator installs the mounting block 202 between the two positioning balls 302e, the limit ball 203d on the support post 203b passes through the limit sleeve 203c in the limit hole 203a. The limit sleeve 203c is made of a soft material with resistance properties. Let the cross-sectional width of the limit sleeve 203c after extrusion be L1, the cross-sectional width of the support post 203b be L2, and the diameter of the limit ball 203d be R. The relationship between L1, L2, and R is set such that R is greater than L1 and L2 is smaller than L1. Thus, after the support post 203b and the limit ball 203d pass through the limit sleeve 203c, the limit sleeve 203c can quickly recover due to its elasticity and resistance properties, thereby realizing stable clamping of the support post 203b and the limit ball 203d, preventing the mounting block 202 from falling off the support post 203b, and increasing the stability of the mounting block 202 after installation.

[0039] The other structure is similar to that of the first embodiment.

The monitoring unit 400 is used to constantly monitor the biogas in the monopile turbine.

[0041] The alarm unit 500 includes a support member 501 provided on the bottom shell 401, a first connecting pipe 502 provided on the support member 501, a second connecting pipe 503 provided on the support member 501, a piping assembly 504 provided on the first connecting pipe 502, and an alarm assembly 505 provided on the second connecting pipe 503.

The support member 501 is attached to the bottom shell 401 and is used to support the alarm assembly 505 and the piping assembly 504, thereby ensuring the stability of the entire alarm system.

[0042] Compared with Example 2, a sensor 403 is further provided in the bottom shell 401, and the sensor 403 is provided with a sensor housing 404. The sensor 403 is used to sense the concentration of biogas in the monopile turbine, and the sensor housing 404 is used to protect the sensor 403 exposed to the outside of the protective shell 107.

[0043] Here, the piping assembly 504 includes a first support pipe 504a provided on the first connecting pipe 502, a pipe joint 504b provided on the first supporting pipe 504a, and an attachment pipe 504c provided on the pipe joint 504b.

Through the pipe joint 504b and the attachment pipe 504c, the piping assembly 504 can be connected to other external pipes, thereby realizing gas transmission and monitoring, and ensuring the integrity and effectiveness of the entire monitoring system.

[0044] In use, the bottom shell 401 is securely attached to the connection base 201 and sealed by the top shell 402, forming a protected space to ensure the safety and stability of the internal monitoring equipment. The sensor 403 is attached to the bottom shell 401 and the sensor housing 404 further protects the sensor 403 and reliably monitors the biogas concentration inside the monopile turbine.

[0045] The support member 501 supports the alarm and piping assembly 504 to ensure the stability of the whole monitoring system.
