Abstract
Description
Technical Field
[0001] This utility model relates to the field of lightning protection devices, and in particular to an adjustable lightning rod. Background Technology
[0002] In observatories with limited installation space, such as those on mountaintops, the coordinated operation of lightning protection and observation equipment faces significant challenges. Existing technologies, such as traditional single-needle lightning rods or fixed-layout multi-needle lightning protection systems, are ill-suited to the confined installation space on mountaintops. On the one hand, if the lightning protection devices are too densely packed, they occupy limited space resources and can easily obstruct the observation field of optical telescopes. On the other hand, reducing the number of lightning protection devices to avoid obstruction results in insufficient protection, especially in mountainous areas with frequent lightning activity, significantly increasing the risk of lightning damage to observatory equipment. Meanwhile, the dome of the mountaintop observatory needs to rotate frequently to track celestial objects. Traditional lightning protection systems often have fixed lightning-attracting components. When the dome rotates to a specific angle, these components can easily enter the telescope's field of view, interfering with observation accuracy. Furthermore, some adjustable lightning-attracting devices suffer from response lag, unable to adjust their position in real time according to the dome's rotation direction. Their drive structures are also difficult to install and maintain in confined spaces, making it challenging to meet the stable operational requirements of a mountaintop environment. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, this invention provides an adjustable lightning rod that can dynamically adjust the height of the lightning-attracting part to ensure the observation effect of the optical telescope.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An adjustable lightning rod includes a mounting part, a dome rotatably connected to the mounting part, one or more lightning-attracting parts are provided on the mounting part, the lightning-attracting parts are slidably connected to the mounting part, a control component is provided on the lightning-attracting parts, a down conductor is provided on the lightning-attracting parts, one end of the down conductor is fixedly connected to the lightning-attracting part, and the other end is connected to a busbar, and the down conductor is provided with a certain amount of surplus.
[0005] Furthermore, the excess length of the down conductor is greater than or equal to the distance between the highest and lowest points of the lightning bolt section.
[0006] Furthermore, a signal transmitter is provided on the dome, and one or more signal receivers are provided on the mounting part. The number of signal receivers is the same as the number of mine-attracting parts and they are arranged alternately.
[0007] Furthermore, the control component includes a support and a slider. The support is mounted on the mounting part, and the slider is slidably connected inside the support. The slider is fixedly connected to the lightning rod.
[0008] Furthermore, a winch and a pulley are provided inside the support section. The winch and the pulley are symmetrically arranged at both ends of the support section. A rope is provided between the winch and the pulley, and a slider is fixedly connected to the rope.
[0009] Furthermore, the rope is a looping lasso.
[0010] Furthermore, the rope is provided with two locking parts, and the slider is provided with a connecting part, which is located between the two locking parts.
[0011] Furthermore, the rope is made of nylon, and the locking part is fixedly connected to the rope using a hot melt injection molding process.
[0012] Furthermore, the two ends of the connecting part are detachably connected, and the connecting part is sleeved with a rope.
[0013] Furthermore, the support portion is provided with a limiting groove, and the slider is provided with a limiting portion, which is slidably connected within the limiting groove.
[0014] Compared with the prior art, the beneficial effects that this utility model can achieve are: 1. By sliding the lightning arrester onto the mounting base and dividing the layout by sector, multiple lightning arresters can be orderly distributed on the same mounting base without occupying excessive additional space. Compared to traditional fixed lightning protection devices, this design is more suitable for confined areas such as mountaintops, maximizing protection coverage within a limited space.
[0015] 2. Addressing the frequent rotation of the dome at the mountaintop observatory, a linkage control system between the signal transmitter and receiver allows the lightning arrester to adjust in real-time according to the dome's rotation direction: the arrester in the direction of movement lowers, while the arrester in the opposite direction rises. This dynamic adjustment mechanism ensures that the telescope is not obstructed by the lightning arrester during observation, resolving the core contradiction of "difficulty in balancing protection and observation" in mountaintop observations.

[0017] The components include: mounting part 1; dome 11; signal transmitter 12; signal receiver 13; support part 2; winch 21; pulley 22; limiting groove 23; rope 24; locking part 241; lightning triggering part 3; slider 31; connecting part 311; limiting part 312; and downleader 32. Detailed Implementation Example 1
[0018] To address the technical problems mentioned in the background art, this application includes a mounting part 1 for supporting the entire device. A dome 11 is movably connected to the mounting part 1, the axis of the dome 11 being collinear with the axis of the mounting part 1. The dome 11 is rotatably connected to the mounting part 1, and the driving scheme of the dome 11 is the same as that used in the prior art. The mounting part 1 is as follows... Figure 1 The setup includes one or more lightning-attracting units 3, slidably connected to a mounting section 1. The mounting section 1 is divided into a certain number of sectors based on the number of lightning-attracting units 3. The lightning-attracting units 3 located in the observation sector are lowered according to the rotation direction of the dome 11 to avoid interfering with the observation of celestial phenomena within that sector by the optical telescope inside the dome 11. A control component is connected to each lightning-attracting unit 3, controlling its movement. The lightning-attracting unit 3 moves vertically along its own axis on the mounting section 1. A lightning-attracting wire 32 is provided at the tail end of each lightning-attracting unit 3, and the tail end of the lightning-attracting wire 32 is connected to a busbar buried in the soil. The lightning-attracting wire 32 has a certain margin, with the margin distance being greater than or equal to the distance between the highest and lowest points of the lightning-attracting unit 3, ensuring that the lightning-attracting unit 3 can maintain the connection between the lightning-attracting wire 32 and the busbar at any height. The protective area of the device for the observatory is increased by using multiple lightning arresters 3. A signal transmitter 12 is installed on the outside of the dome 11, and this transmitter is associated with the optical telescope inside the dome. One or more signal receivers 13 are deployed on the mounting section 1, the number matching the number of lightning arresters 3, and the signal receivers 13 and lightning arresters 3 are arranged in an alternating manner. The signal receivers 13 and signal transmitters 12 are on the same horizontal plane, a design that provides a basis for stable signal transmission. When a signal receiver 13 receives a signal from a signal transmitter 12, it immediately triggers the control component on the corresponding lightning arrester 3, causing the control component to drive the lightning arrester 3 to move, thereby adjusting the position of the lightning arrester 3. Preferably, the signal transmitter 12 and signal receiver 13 use infrared signals for data transmission. Infrared signals have the characteristics of stable transmission and strong anti-interference ability, which can better meet the signal interaction requirements of the device.
[0019] As the dome 11 rotates, the signal transmitter 12 moves in the same direction and at the same speed as the dome 11. The signal emitted by the transmitter 12 during this movement is received by the signal receiver 13 along the moving path. Upon receiving the corresponding signal, the signal receiver 13 drives the two adjacent mine-attracting sections 3. The mine-attracting section 3 located in the direction of the dome 11's movement descends, while the mine-attracting section 3 located in the opposite direction of the dome 11's movement rises. In this way, the multiple mine-attracting sections 3 ensure the protective effect of the dome 11 while preventing interference with the observations of the optical telescope installed inside the dome 11.
[0020] When using the device: The dome 11 rotates in a designated direction according to the area to be observed. During the rotation of the dome 11, the signal transmitter 12 continuously transmits signals. When the signal receiver 13 located on the rotation path of the dome 11 receives the signal, it controls the lightning arrester 3 located at both ends of the signal receiver 13 to move, so as to ensure that the optical telescope can observe normally. Example 2
[0021] Based on Embodiment 1, the control component includes, as follows: Figure 4 The support portion 2 and slider 31 are shown. The mounting portion 1 is provided with a support portion 2 for placing the mine-attracting part 3. The slider 31 is slidably connected inside the support portion 2, and the slider 31 supports the bottom end of the mine-attracting part 3. By controlling the height of the slider 31, the mine-attracting part 3 on the slider 31 can move in the same direction. The support portion 2 is provided with a winch 21, a pulley 22, and a rope 24. The winch 21 and the pulley 22 are respectively located at both ends of the support portion 2, and the winch 21 and the pulley 22 are connected by the rope 24. The rope 24 is a looping rope, and one end of the slider 31 is fixedly connected to the rope 24. The winch 21 drives the rope 24, allowing the slider 31 to move back and forth along the length of the support portion 2. The slider 31 is provided with... Figure 5 The connecting part 311 shown is provided with a rope 24 as shown. Figure 6 The locking part 241 shown has two components, and a connecting part 311 is provided between the two locking parts 241. The connecting part 311 is limited by the two locking parts 241 to ensure that the slider 31 can move in the same direction during the rotation of the rope 24. Preferably, the rope 24 is a nylon rope, and the locking parts 241 are fixed to the rope 24 by hot melt injection molding. The two ends of the connecting part 311 are detachably connected and fixed by bolts to ensure that the connecting part 311 can be detachably connected to the rope 24.
[0022] The slider 31 is provided with a limiting part 312, and the support part 2 is provided with a limiting groove 23. The limiting part 312 is slidably connected in the limiting groove 23, and the slider 31 is restricted from rotating in the support part 2 by the cooperation of the limiting groove 23 and the limiting part 312.
