Description

Technical Field

[0001] This utility model relates to the field of equipment monitoring, and in particular to an equipment tilt monitoring device. Background Technology

[0002] As the third largest source of electricity after thermal and hydropower, wind power is expanding from land to sea. The trend in offshore wind power development is shifting from small-scale demonstration projects in nearshore, shallow water areas to large-scale, centralized development in open ocean and deep water. Currently, the main method for transmitting large-scale offshore wind power to the onshore power grid is flexible direct current transmission technology (VSC-HVDC), which is an ideal choice due to its flexibility and efficiency.

[0003] However, the harsh marine environment, especially for large-scale deep-sea wind farms located far from land, typically requires unmanned management. This poses challenges to the safe and stable operation of critical infrastructure such as offshore converter stations. One particularly prominent issue is structural resonance caused by wave impacts on the jacket support structure. Although a single wave impact may only cause minor vibrations, these vibrations, accumulated over time, can lead to regular vibration patterns in medium and large-sized equipment inside the structure, resulting in equipment tilting and creating significant safety hazards. Furthermore, the inability to install tilt monitoring devices on the exterior of some high-voltage power equipment greatly complicates monitoring. Therefore, this paper proposes a tilt monitoring device to address these issues. Utility Model Content

[0030] like Figure 1-9 As shown, an equipment tilt monitoring device is mainly used to monitor the swing amplitude of medium and large power equipment in an offshore converter station in real time. It includes one or more linearly arranged equipment bodies 1. The equipment body 1 can be an indoor reactor or a high-voltage surge arrester. The monitoring device includes infrared transmitters 2 and infrared receivers 3 arranged on the left and right sides of the equipment body 1, respectively. There are two corresponding infrared transmitters 2 and infrared receivers 3, and they form infrared monitoring lines 4 located on the front and rear sides of the equipment body 1, respectively.

[0031] With this design, the tilt of the main body 1 of the device can be measured indirectly by infrared beam transmission. If the swing amplitude of the device under test is large and the tilt exceeds the beam transmission area of ​​the beam transmission sensor, the infrared monitoring line 4 between the infrared beam transmitter 2 and the infrared beam receiver 3 will be blocked. Thus, remote unmanned monitoring can be achieved by sending out alarm information.

[0032] The monitoring device also includes two position adjustment mechanisms 5, which are used to adjust the relative positions of the two infrared transmitters 2 and the two infrared receivers 3, respectively. Each mechanism includes a height adjustment component 50, a horizontal adjustment component 51 that can be raised and lowered on the height adjustment component 50, a spacing adjustment component 52 that can be moved laterally on the horizontal adjustment component 51, and two infrared transmitters 2 or two infrared receivers 3 that can be adjusted in spacing on the spacing adjustment component 52.

[0033] With this design, the spacing between the two infrared transmitters 2 or the two infrared receivers 3 can be adjusted by the spacing adjustment component 52 to adapt to the front and rear width of the main body 1. The lateral adjustment component 51 can adjust the lateral position of the infrared transmitters 2 and the infrared receivers 3, so that the main body 1 can be positioned between the two infrared monitoring lines 4. The height adjustment component 50 facilitates the adjustment of the detection height of the infrared monitoring lines 4.

[0034] In a preferred embodiment, the height adjustment component 50 includes a base 501. The top of the base 501 is provided with a lifting frame 502 with an open front. The lifting frame 502 is provided with two limiting slide rods 503 and a rotatable lifting screw 504. The lifting frame 502 is provided with a bearing for rotating the lifting screw 504. The top of the lifting screw 504 passes through the lifting frame 502 and is connected to a lifting handle 505. The outside of the limiting slide rods 503 is slidably provided with a lifting seat 506 that is threadedly engaged with the lifting screw 504.

[0035] With this design, the lifting screw 504 can be rotated by the lifting handle 505, and the lifting seat 506 can achieve its own lifting effect by rotating the lifting screw 504 and limiting the limit slide 503.

[0036] In a preferred embodiment, a diagonal brace 507 is provided between the base 501 and the lifting frame 502. In this embodiment, there are two diagonal braces 507, which are respectively provided on both sides of the lifting frame 502, thereby improving the stability of the lifting frame 502.

[0037] Furthermore, the lateral adjustment assembly 51 includes a lateral frame 510 disposed on the front of the lifting seat 506 and having an open front. The inner top and bottom walls of the lateral frame 510 are provided with lateral sliding grooves 511 with open ends. A notch 512 is provided on one side of the back plate of the lateral frame 510. Two bearing seats 513 are symmetrically arranged on the back of the lateral frame 510. A rotating shaft 514 is rotatably disposed between the two bearing seats 513. One end of the rotating shaft 514 passes through the bearing seat 513 and is connected to a lateral handle 516. A bearing for rotating the rotating shaft 514 is disposed in the bearing seat 513. A transmission gear 515 located at the notch 512 is provided on the external drive of the rotating shaft 514. Thus, the rotating shaft 514 can be rotated between the two bearing seats 513 by means of the lateral handle 516, thereby driving the transmission gear 515 to rotate.

[0038] The spacing adjustment component 52 includes an adjustment frame 520 slidably disposed in the transverse frame 510. The upper and lower sides of the adjustment frame 520 are respectively provided with transverse slide bars 521 that slide in cooperation with the transverse slide groove 511. The back of the adjustment frame 520 is embedded with a rack 517 that meshes with the transmission gear 515. The embedded method can avoid affecting the normal transverse movement of the spacing adjustment component 52.

[0039] This design allows the lateral adjustment component 51 to rise and fall with the lifting seat 506, thereby achieving the effect of adjusting the monitoring height. In addition, the lateral movement of the spacing adjustment component 52 can be adjusted by the meshing relationship between the transmission gear 515 and the rack 517, thereby adjusting the lateral position of the detection.

[0040] In the preferred embodiment, both ends of the transverse slide bar 521 are provided with limit seats 522, which can prevent the transverse frame 510 from detaching during transverse movement.

[0041] Furthermore, the front of the adjusting frame 520 is open, and the spacing adjusting assembly 52 also includes a positive and negative threaded screw 523 rotatably disposed in the adjusting frame 520. The adjusting frame 520 is provided with a bearing for rotating the positive and negative threaded screw 523. One end of the positive and negative threaded screw 523 passes through the adjusting frame 520 and is connected to a spacing adjusting handle 524, so that the positive and negative threaded screw 523 can be rotated through the spacing adjusting handle 524. Both of the two opposite threaded sections of the positive and negative threaded screw 523 are threaded with internal threaded shafts 526. The inner top wall and inner bottom wall of the adjusting frame 520 are provided with adjusting limit grooves 525. The internal threaded shaft 526 is provided with adjusting limit blocks 527 that slide in cooperation with the adjusting limit grooves 525.

[0042] With this design, the distance between the two internal threaded shafts 526 can be adjusted by adjusting the limit of the limit block 527, allowing them to move toward each other or away from each other.

[0043] Two infrared transmitters 2 or two infrared receivers 3 are respectively mounted on two internal threaded shafts 526. The infrared transmitters 2 or infrared receivers 3 are connected to the internal threaded shafts 526 by threaded installation.

[0044] This allows for adjustment of the spacing between the two infrared transmitters 2 or the two infrared receivers 3.

[0045] It should be noted that the two position adjustment mechanisms 5 are fixed to the ground on both sides of the main body 1 by bolts. Before fixing, their levelness needs to be measured.

[0046] To ensure the normal operation of the infrared transmitter 2 and the infrared receiver 3, the monitoring device also includes an infrared beam monitoring cabinet. The infrared beam monitoring cabinet is equipped with a power supply circuit and a communication circuit that connects the infrared transmitter 2 and the infrared receiver 3, which are used to realize real-time sensing and remote transmission of the tilt status of the device under test.

[0047] The power supply circuit includes a distribution bus that is electrically connected to the UPS system and equipped with a circuit breaker at its front end. The distribution bus is electrically connected to the UPS system through the circuit breaker, providing a stable and reliable AC220V power input for the entire system. The distribution bus has four load branches connected in parallel. The first load consists of a parallel display and industrial control host; the second load consists of a parallel power supply module, signal hub, and I / O module; the third load consists of a parallel power supply module and photoelectric converter; and the fourth load consists of the power supply module for infrared transmitter 2 and infrared receiver 3. Each load branch has a circuit breaker at its front end to achieve independent protection and fault isolation functions. The second and third loads are equipped with time relays at their front ends to control the power-on sequence.

[0048] In the preferred embodiment, the communication loop consists of an infrared beam transmitter 2 and an infrared beam receiver 3 connected in series with a photoelectric converter to convert the acquired electrical signals into optical signals for output. The photoelectric converter is connected in parallel with a signal hub to achieve centralized processing of multi-point data. The signal hub is connected in series with the industrial control computer backend via COM:1 interface TX and RX to complete further data analysis and forwarding. The industrial control computer backend is connected to a Cat5e shielded network cable via LAN1 interface, so that the processed data can be uploaded to the integrated online monitoring system host cabinet via the LAN network to realize remote monitoring and alarm functions. The monitor and the industrial control host are connected point-to-point via video cable to ensure on-site visualization. The I / O module interacts with the signal hub via a standard bus such as RS485 or Ethernet to complete data acquisition and command issuance from external sensors.

[0049] In the preferred embodiment, the cabinet lighting equipment is also connected in parallel to the power distribution bus via a circuit breaker, thereby ensuring the power supply for the cabinet lighting.

[0050] This design not only enables high-precision monitoring of the equipment's tilt status, but also provides excellent anti-interference capabilities, maintainability, and scalability. It can adapt to the long-term unattended operation requirements in complex marine environments and effectively ensure the safe and stable operation of major infrastructure such as offshore wind power.

[0051] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
