Description

【0001】
【発明の属する技術分野】
本発明は、屋外やビルの屋上等に設置されて360°周囲の環境を撮影する撮影装置で、詳しくは、監視カメラや観測カメラ等の遠近撮影用カメラを360°以上に連続回転させて360°周囲の環境を連続して撮影する環境撮影装置に関する。
【0002】
【従来の技術】
競輪場等の競技トラックの中央に設置された鉄塔の上端でカメラを360°以上に連続回転させて、競技トラックを走行する競技者を連続的に撮像する監視カメラ装置は、カメラで撮像された画像を遠隔地で監察することで、競技者の着順を決めたり競技トラックでの競技者の不正行為を監視等する。このような屋外に設置される監視カメラ装置等の環境撮影装置においては、落雷からカメラを保護するために避雷針をカメラの近くに設置するようにしている。
【0003】
【発明が解決しようとする課題】
鉄塔の上端に回転式カメラと避雷針を設置した環境撮影装置においては、鉄塔の上端が小スペースである関係から回転式カメラの側方近傍の定位置に棒状の避雷針を略鉛直に配置するようにしているが、この場合、カメラが避雷針の在る方向に回転するとカメラの視野(画角)に避雷針が入って、カメラで撮影された画像に避雷針像が最接近像として写る。そのため、競技トラックの競技者をカメラで連続して撮影して、カメラ画像から着順や不正行為等を監察する場合に、画像に写った避雷針像が邪魔になって正確な着順等を監察することができなくなる不具合が発生することがある。
【0004】
そこで、上記不具合が発生しないように鉄塔上における避雷針の取付位置を変更することが行われているが、この避雷針取付位置の変更だけでは、競技トラックの360°ある全周のいずれの箇所で起こるか分からない不正行為に対しては十分に対処できない。また、避雷針を短くしたり、カメラから遠く離すようにして、カメラの撮影画像に写る避雷針像を小さくすれば、上記不具合の発生が少なくできるが、これでは避雷針の落雷からカメラを保護する機能が低下する。
【0005】
本発明は、上記監視カメラ装置における避雷針問題に鑑みてなされたもので、回転式カメラで撮影された画像から避雷針像を無くし、かつ、落雷からカメラを保護する機能の確保を容易にし、特に高所監視カメラ装置に好適な環境撮影装置を提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明は上記目的を達成するため、遠近撮影用カメラとこのカメラを落雷から保護する避雷手段とを回転支持体に装設すると共に前記避雷手段をカメラの視野外位置に配置し、前記避雷手段がカメラ視野外にある状態で回転支持体によりカメラを回転させるようにしたことを特徴とする(請求項1の発明)。
【0007】
ここでの避雷手段は、通常の棒状避雷針やプレート状避雷器、箱状避雷器等である。この避雷手段と回転式カメラを同じ回転支持体に固持させて、カメラの回転時に避雷手段もカメラと一体に回転させようにする。したがって、回転支持体に固持されたカメラの視野(画角、写角)から避雷手段を外すようにして避雷手段を回転支持体に固持させておくと、カメラがいずれの角度を回転してもその視野に避雷手段が入らず、カメラの撮影画像に避雷手段の像が写らない。このような避雷手段はカメラの近傍に配置することが可能であり、避雷手段が小型であってもカメラは避雷手段で確実に落雷から保護される。
【0008】
本発明の請求項2の発明は、上記避雷手段が、回転支持体に固持されたカメラを囲うかご状避雷器であることを特徴とする。このかご状避雷器は、カメラを収容するかごを複数枚の導電網で形成したものでよく、カメラを囲うことによって避雷手段全体が小型サイズであってもカメラへの落雷を確実に防止する。
【0009】
本発明の請求項3の発明は、上記回転支持体が設置された支柱と回転支持体との間に、支柱側に設けられてアースした固定集電子と、回転支持体側に設けられて回転時に前記固定集電子に電気的接触状態で摺動することにより避雷手段を前記固定集電子を介してアースする回転集電子とを配設した集電装置を具備したことを特徴とする。ここでの集電装置は、回転する避雷手段と固定された支柱との間の常時の電気的接続を安定したものにして、回転する避雷手段を確実にアースする。この場合、支柱が鉄塔であれば集電装置が鉄塔にアースされる。
【0010】
さらに、本発明の請求項4の発明は、上記集電装置のおける固定集電子が回転支持体の回転中心を中心とする円環状の集電レールで、回転支持体に固定された保護カバーを前記集電レール上に被せたことを特徴とする。この保護カバーにより、集電レールに落下する異物、例えば鳩等の鳥の糞や雨、雪、煤塵等から保護することができ、これにより、集電装置の集電レールと回転集電子の電気的接触状態が常に安定したものとなる。
【0011】
【発明の実施の形態】
本発明の一実施形態を図1乃至図7を参照して説明する。
【0012】
図1乃至図4に示される環境撮影装置は、鉄塔等の支柱50の上端の高所に設置される回転式監視カメラ装置に適用したもので、支柱50の上端に設置された水平な回転支持体10上に遠近撮影用カメラ20と避雷手段30を固持させると共に、回転支持体10と支柱50の間に避雷手段30を常時アースするための集電装置40を配備した構造を有する。支柱50は図示しない地面にアースされた状態で立設された鉄塔等であり、支柱50の上面にモータ装置60が設置され、モータ装置60上に回転支持体10が鉛直な中心軸を中心に360°以上に連続回転可能に設置される。モータ装置60と回転支持体10の間に、支柱50を介して避雷手段30をアースする集電装置40が配備される。
【0013】
回転支持体10は、例えばカメラ20を連続回転可能に支持する回転式のカメラ支持用雲台である。カメラ20は遠隔操作される監視カメラであり、周りの環境を撮影するカメラ本体21と、カメラ本体21に被せられてカメラ本体21を支持して保護する分割型のカメラカバー22を備える。カメラカバー22が回転支持体10上に立設された脚片23に上下に揺動可能に支持される。以上の支柱50上のモータ装置60、雲台式回転支持体10、カバー付きカメラ20の各々は、既設の回転式高所監視カメラ装置のモータ装置、雲台、カメラの適用が可能であり、このように既設設備を利用することで設備投資が安くて済む。
【0014】
避雷手段30は回転支持体10上にカメラ20から少し離れた位置で、かつ、カメラ20の視野外の定位置に固持される。このような避雷手段30は、1本或いは複数本の棒状避雷針や、1枚或いは複数枚の導電板のプレート式避雷器、複数枚の導電板を箱状に組み立てた箱状避雷器、複数枚の導電網を箱状に組み立てたかご状避雷器等が適用可能である。特に、支柱50の上端のような高所に設置される環境撮影装置にあっては、強風に対してより安全な構造の避雷手段30が必要であることから棒状避雷針、かご状避雷器が適切であり、図1乃至図5に避雷手段30としてかご状避雷器を示す。以下、必要に応じて避雷手段30をかご状避雷器30と称する。
【0015】
かご状避雷器30の具体例を図1乃至図4に、分解図を図5に示し説明すると、これは図5に示すように複数枚の矩形の導電網31を、矩形箱状の補強用導電フレーム枠32に組み付けて構成される。複数の各導電網31は軽量なアルミニウム製品であり、補強用導電フレーム枠32は軽量な導電網31を補強する例えばステンレス製品である。導電フレーム枠32は、カメラ20の全体を囲う矩形箱形枠で、両側面の開口の中央に縦桟33が連結される。この導電フレーム枠32に対応して導電網31は、導電フレーム枠32の両側面開口に設置される前後2枚で計4枚の側面網31a、31a、…と、導電フレーム枠32の上面開口に設置される前後2枚の上面網31b、31bと、導電フレーム枠32の前面開口に設置される1枚の前面網31cと、導電フレーム枠32の後面開口に設置される後面網31dで構成される。導電網31の各々は導電フレーム枠32の外面に例えば蝶ネジ34を使って手動で脱着可能に取り付けられる。導電フレーム枠32の下面は開口したままで、この開口からカメラ20を入れることで、かご状避雷器30がカメラ20を囲んだ状態で回転支持体10上に固持される。
【0016】
図5に示すように、導電網31の側面網31aと上面網31bを前後2枚に分けたのは、次の理由による。すなわち、支柱50の上端のような高所でかご状避雷器30を組み立てたり、分解する作業において、仮に導電網31の側面網を1枚で構成しておくと重量が増して作業が難しくなるが、これを2枚に分けておくと2枚各々が軽量となって作業がし易くなる。また、カメラ20の点検作業時にカメラカバー22を手動で外す作業においては、導電網31の上面網31bを2枚に分けて2枚各々を軽量化することで、作業がし易くなる。また、このような高所での手動による各種作業は、導電フレーム枠32の例えば側面の縦桟33を、図5の円弧矢印で示すように前後に手動で倒れるようにして、縦桟33を倒して作業するようにすれば、作業がし易くなる。
【0017】
また、かご状避雷器30の導電網31と導電フレーム枠32は、蝶ネジ34や導電塗料等で電気的機械的に連結一体化され、回転支持体10上に固持されると集電装置40を介してアースされる。このようにかご状避雷器30を常時アースした状態にしてカメラ20を囲うことで、カメラ20を落雷から確実に保護する。この場合、かご状避雷器30がカメラ20の上方域、両側方域、前後域のそれぞれを囲うので、カメラ20をそのほぼ全方向からの落雷から保護して、信頼性の高い避雷針効果が期待できる。なお、かご状避雷器30はカメラ20の下方域を囲うことがないが、この下方域には回転支持体10が在り、さらに、支柱50の上端部には図1乃至図4の鎖線で示す位置に作業台装置70が設置されるのが通常であり、この作業台装置70はカメラ20の下方域を囲ってカメラ20の下方からの落雷に対して避雷針機能を発揮するので、かご状避雷器30でカメラ20の下方域を囲わなくてもよい。なお、作業台装置70とは、鉄塔等の支柱50の上端部外周に固設された鉄板製品の円形作業踏台、この作業踏台の外周に立設された鉄棒製の円形枠状手摺り等であり、鉄塔である支柱50にアースされる。
【0018】
回転支持体10とカメラ20と一体に連続回転するかご状避雷器30を常時アースして避雷効果を安定したものにする集電装置40の具体例が、図6乃至図7に示される。この集電装置40は、支柱側(固定側)に固定されて支柱50を介してアースされた固定集電子41と、回転支持体側(回転側)に固定されて、固定集電子41と常時電気的接触した状態で回転支持体10と一体的に回転する回転集電子42を備える。固定集電子41は、例えば回転支持体10の回転中心線を中心とする円環状の集電レールで、以下、必要に応じて固定集電子41を集電レール41と称する。
【0019】
この集電レール41は、図7に示すように絶縁性レール支持枠43に水平に固定される。レール支持枠43は、モータ装置60又は支柱50の固定部分に固定される。回転集電子42は、図7(B)に示すように集電レール41の上面に内蔵バネ材44を介して摺動可能に弾圧接触する集電ブラシ等で、回転支持体10と一体に回転して円環状の集電レール41上を常時摺動して移動する。回転集電子42は単数或いは複数が設置され、図2乃至図4においては集電レール41の180°間隔の2箇所に一対を設置している。この一対の回転集電子42の各々は避雷設備30にリード線等で電気的接続される。
【0020】
また、集電装置40には、固定された集電レール41の上面を覆う絶縁性の保護カバー45と、回転集電子42を囲う絶縁性の透明カバー46が必要に応じて配備される。保護カバー45は、回転支持体10側に固定されて回転集電子42と一体に回転する円環キャップ状の絶縁板で、180°間隔の2箇所に図示しない切り欠きが形成され、この切り欠きに回転集電子42が配置されて集電レール41に弾圧接触する。この保護カバー45は、集電レール41の上面に鳥の糞等の異物が落下するのを防止するカバーである。つまり、集電レール41の上面に鳥の糞が落下すると、この糞が集電レール41と回転集電子42の電気的接触状態を悪化させて避雷器30の避雷針機能を低下させることがあるが、集電レール41に保護カバー45を被せて保護カバー45に鳥の糞を落下させて集電レール41への落下付着を防止するようにしておくと、避雷器30の避雷針機能が低下する心配が無くなる。また、透明カバー46は、回転集電子42の全体を覆うことで回転集電子42への異物の落下と付着を防止して集電レール41との電気的接触状態を常に安定したものとし、かつ、透明カバー46を透視することで回転集電子41の摩耗状態や集電レール41上面の汚れ状態の目視監察が容易にできるようになる。
【0021】
図1に示すように支柱50の上端の高所で回転支持体10とカメラ20、かご状避雷器30を一体的に連続回転させると、カメラ20と避雷器30の相対位置が変わらずに連続回転するカメラ20の視野に避雷器30のいずれの箇所も入らない。したがって、カメラ20が連続して撮影する画像に避雷針像(避雷器像)が写らず、この画像から撮影された環境の正確な監察、観測等が実行できるようになる。また、高所のカメラ20が常に一定した形態で避雷器30に囲まれ、回転する避雷器30が集電装置40を介して常に安定した状態でアースされているので、カメラ20が落雷から常に安定した状態で保護される。
【0022】
なお、本発明は屋外の高所に設置される環境撮影装置に限らず、落雷の可能性のある低所に設置される環境撮影装置等にも有効に適用される。
【0023】
【発明の効果】
請求項1の発明によれば、回転支持体の連続回転でカメラと避雷手段が相対位置変わらずに一体となって連続回転するので、連続回転するカメラのいずれの回転角度においてもカメラの視野に避雷手段が入らず、したがって、カメラで撮影された画像に避雷手段の像が写らずにカメラの撮影画像の監察が避雷手段像に邪魔されることなく正確に行えるようになって、環境撮影装置の信頼性改善が図れる。
【0024】
請求項2の発明によれば、カメラを囲うかご状避雷器がカメラの前後左右や上方からの落雷に対してカメラを保護するため、カメラの落雷に対する保護機能に優れた、高信頼度の環境撮影装置が提供できる。
【0025】
請求項3の発明によれば、回転する避雷手段のアース状態が集電装置を介することで安定したものとなり、避雷手段のカメラを落雷から保護する機能が常に安定して確保される。
【0026】
請求項4の発明によれば、集電装置の固定集電子である集電レールの上面が保護カバーで覆われているので、集電レール上に鳥の糞等が落下して付着する心配が無くなり、そのため、集電レールと回転集電子の電気的接触が常に安定したものとなって、集電装置の信頼性が良くなり、集電装置の保守が容易になる。

BACKGROUND OF THE INVENTION
The present invention is an imaging apparatus that is installed outdoors or on a rooftop of a building and shoots an environment around 360 °. Specifically, a perspective camera such as a surveillance camera or an observation camera is continuously rotated 360 ° or more to 360 °. ° The present invention relates to an environmental imaging device that continuously captures the surrounding environment.
[0002]
[Prior art]
The surveillance camera device that continuously images the athletes traveling on the competition track by rotating the camera continuously at 360 ° or more at the upper end of the steel tower installed at the center of the competition track such as a bicycle racetrack was captured by the camera. By monitoring images at remote locations, the order of the competitors can be determined, and the player's cheating on the competition track can be monitored. In such an environment photographing device such as a surveillance camera device installed outdoors, a lightning rod is installed near the camera in order to protect the camera from lightning.
[0003]
[Problems to be solved by the invention]
In an environmental photography device with a rotary camera and lightning rod installed at the top of the steel tower, a rod-shaped lightning rod should be placed almost vertically at a fixed position near the side of the rotary camera because the top of the steel tower is small. However, in this case, when the camera rotates in the direction in which the lightning rod is located, the lightning rod enters the field of view (angle of view) of the camera, and the lightning rod image appears as the closest image on the image taken by the camera. Therefore, when the athletes on the competition track are continuously photographed with the camera and the order of arrival or fraud is monitored from the camera image, the lightning rod image reflected in the image gets in the way and monitors the exact order of arrival. Problems that can not be made may occur.
[0004]
Therefore, the lightning rod mounting position on the steel tower is changed so as not to cause the above-mentioned problem, but this change of the lightning rod mounting position only occurs at any part of the 360 ° circumference of the competition track. We cannot deal with fraud that we don't know enough. In addition, if the lightning rod is shortened or far away from the camera and the lightning rod image in the captured image of the camera is made small, the occurrence of the above problems can be reduced, but this has a function to protect the camera from lightning strike of the lightning rod. descend.
[0005]
The present invention has been made in view of the problem of lightning rods in the monitoring camera device described above, and eliminates the lightning rod image from an image photographed by a rotary camera and facilitates ensuring the function of protecting the camera from lightning strikes. It is an object of the present invention to provide an environment photographing device suitable for a site monitoring camera device.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is provided with a perspective camera and a lightning protection means for protecting the camera from lightning strikes on a rotating support, and the lightning protection means is disposed at a position outside the field of view of the camera, and the lightning protection means. The camera is rotated by a rotating support body in a state where the lens is out of the camera field of view (invention of claim 1).
[0007]
The lightning protection means here is a normal rod-shaped lightning rod, plate-shaped lightning arrester, box-shaped lightning arrester or the like. The lightning protection means and the rotary camera are fixed to the same rotating support so that the lightning protection means is rotated integrally with the camera when the camera rotates. Therefore, if the lightning protection means is secured to the rotating support so as to remove the lightning protection means from the field of view (view angle, angle of view) of the camera held on the rotating support, the camera can rotate at any angle. The lightning protection means does not enter the field of view, and the image of the lightning protection means does not appear in the image taken by the camera. Such lightning protection means can be arranged in the vicinity of the camera, and even if the lightning protection means is small, the camera is reliably protected from lightning by the lightning protection means.
[0008]
The invention according to claim 2 of the present invention is characterized in that the lightning arrester is a squirrel-cage lightning arrester surrounding a camera held on a rotating support. This cage lightning arrester may be formed of a plurality of conductive nets for a cage for accommodating a camera, and by surrounding the camera, lightning strike to the camera is surely prevented even if the entire lightning arresting means is of a small size.
[0009]
According to a third aspect of the present invention, there is provided a stationary current collector provided on the support column side and grounded between the support column on which the rotation support member is installed and the rotation support member, and provided on the rotation support member side during rotation. It is characterized by comprising a current collector provided with a rotating current collector for grounding the lightning protection means through the fixed current collector by sliding in contact with the fixed current collector. The current collector here stabilizes the electrical connection at all times between the rotating lightning protection means and the fixed column, and reliably grounds the rotating lightning protection means. In this case, if the column is a steel tower, the current collector is grounded to the steel tower.
[0010]
Further, according to a fourth aspect of the present invention, there is provided a protective cover fixed to the rotary support, wherein the fixed current collector in the current collector is an annular current collector rail centering on the rotation center of the rotary support. It is characterized by being placed on the current collecting rail. With this protective cover, it is possible to protect against foreign matter falling on the current collector rail, such as bird droppings such as pigeons, rain, snow, dust, and the like. The contact state is always stable.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS.
[0012]
The environment photographing apparatus shown in FIGS. 1 to 4 is applied to a rotary monitoring camera device installed at a high position on the upper end of a support column 50 such as a steel tower. The camera 10 and the lightning protection means 30 are fixed on the body 10 and a current collector 40 for always grounding the lightning protection means 30 between the rotary support 10 and the support 50 is provided. The support 50 is a steel tower or the like standing on the ground (not shown). The motor device 60 is installed on the upper surface of the support 50, and the rotary support 10 is centered on the motor device 60 around the vertical central axis. It is installed so that it can be continuously rotated at 360 ° or more. Between the motor device 60 and the rotary support 10, a current collector 40 for grounding the lightning protection means 30 via the support column 50 is provided.
[0013]
The rotary support 10 is, for example, a rotary camera support head that supports the camera 20 so as to be continuously rotatable. The camera 20 is a remotely operated surveillance camera, and includes a camera body 21 that captures the surrounding environment, and a split-type camera cover 22 that covers the camera body 21 and supports and protects the camera body 21. A camera cover 22 is supported by a leg piece 23 erected on the rotary support 10 so as to be swingable up and down. Each of the motor device 60, the pan head rotation support body 10, and the camera with cover 20 on the support column 50 can be applied to a motor device, a pan head, and a camera of an existing rotary height monitoring camera device. Thus, capital investment can be reduced by using existing facilities.
[0014]
The lightning protection means 30 is held on the rotary support 10 at a position slightly away from the camera 20 and at a fixed position outside the field of view of the camera 20. Such lightning protection means 30 includes one or a plurality of rod-shaped lightning arresters, a plate-type lightning arrester of one or a plurality of conductive plates, a box-type lightning arrester assembled from a plurality of conductive plates in a box shape, a plurality of conductive elements A cage lightning arrester or the like in which a net is assembled in a box shape can be applied. In particular, in an environmental photographing apparatus installed at a high place such as the upper end of the support column 50, a lightning arrester 30 having a structure that is safer against strong winds is necessary. FIG. 1 to FIG. 5 show a cage lightning arrester as the lightning protection means 30. Hereinafter, the lightning arrester 30 is referred to as a cage lightning arrester 30 as necessary.
[0015]
A specific example of the cage arrester 30 is shown in FIGS. 1 to 4 and an exploded view is shown in FIG. 5. This is illustrated in FIG. 5 in which a plurality of rectangular conductive nets 31 are connected to a rectangular box-shaped reinforcing conductive material. It is configured to be assembled to the frame 32. Each of the plurality of conductive nets 31 is a lightweight aluminum product, and the reinforcing conductive frame 32 is, for example, a stainless steel product that reinforces the lightweight conductive net 31. The conductive frame frame 32 is a rectangular box frame that surrounds the entire camera 20, and a vertical beam 33 is connected to the center of the opening on both side surfaces. Corresponding to the conductive frame frame 32, the conductive mesh 31 is installed in the opening on both side surfaces of the conductive frame frame 32 in the front and rear, and a total of four side meshes 31a, 31a,. The front and rear two upper surface nets 31b and 31b installed on the front side, the one front net 31c installed on the front opening of the conductive frame frame 32, and the rear net 31d installed on the rear opening of the conductive frame frame 32. Is done. Each of the conductive nets 31 is detachably attached to the outer surface of the conductive frame 32 using, for example, a thumbscrew 34. When the camera 20 is inserted through the opening while the lower surface of the conductive frame 32 is open, the cage-type lightning arrester 30 is firmly held on the rotating support 10 while surrounding the camera 20.
[0016]
As shown in FIG. 5, the side net 31a and the top net 31b of the conductive net 31 are divided into two front and rear sheets for the following reason. That is, in assembling or disassembling the cage arrester 30 at a high place such as the upper end of the support column 50, if the side net of the conductive net 31 is composed of a single piece, the weight increases and the work becomes difficult. If this is divided into two sheets, each of the two sheets will be lighter and work will be easier. Further, in the work of manually removing the camera cover 22 during the inspection work of the camera 20, the work is facilitated by dividing the upper surface mesh 31b of the conductive mesh 31 into two pieces and reducing the weight of each two pieces. Further, various manual operations at such high places are carried out by vertically tilting the vertical beam 33 on the side surface of the conductive frame frame 32, for example, as shown by the arc arrows in FIG. If it is made to work down, it will be easier to work.
[0017]
Further, the conductive net 31 and the conductive frame frame 32 of the cage lightning arrester 30 are electrically and mechanically connected and integrated with a thumbscrew 34, a conductive paint, or the like, and when held on the rotary support 10, the current collector 40 is mounted. Is grounded. Thus, the camera 20 is reliably protected from lightning by surrounding the camera 20 with the cage-type lightning arrester 30 being always grounded. In this case, since the cage lightning arrester 30 surrounds the upper area, both side areas, and the front and rear areas of the camera 20, the camera 20 can be protected from lightning strikes in almost all directions, and a highly reliable lightning rod effect can be expected. . The cage lightning arrester 30 does not enclose the lower area of the camera 20, but the rotation support 10 is present in the lower area, and the position indicated by the chain line in FIGS. In general, a work table device 70 is installed, and the work table device 70 surrounds a lower area of the camera 20 and exhibits a lightning rod function against a lightning strike from the lower side of the camera 20. Thus, the lower area of the camera 20 need not be enclosed.

Then, it always slides and moves on the annular current collecting rail 41. One or a plurality of the rotating current collectors 42 are installed. In FIGS. 2 to 4, a pair is installed at two positions of the current collecting rail 41 at intervals of 180 °. Each of the pair of rotating current collectors 42 is electrically connected to the lightning arrester 30 by a lead wire or the like.
[0020]
The current collector 40 is provided with an insulating protective cover 45 covering the upper surface of the fixed current collecting rail 41 and an insulating transparent cover 46 surrounding the rotating current collector 42 as necessary. The protective cover 45 is an annular cap-shaped insulating plate that is fixed to the rotating support 10 and rotates integrally with the rotating current collector 42. Notches (not shown) are formed at two positions at intervals of 180 °. Rotating current collector 42 is arranged in contact with the current collecting rail 41 in an elastic manner. The protective cover 45 is a cover that prevents foreign matters such as bird droppings from falling on the upper surface of the current collecting rail 41. That is, when bird droppings fall on the upper surface of the current collecting rail 41, the droppings may deteriorate the electrical contact state between the current collecting rail 41 and the rotating current collecting 42, thereby reducing the lightning rod function of the lightning arrester 30. If the current collecting rail 41 is covered with the protective cover 45 so that bird droppings are dropped on the protective cover 45 to prevent the light collecting rod 41 from being attached to the current collecting rail 41, the lightning rod function of the lightning arrester 30 may not be deteriorated. . In addition, the transparent cover 46 covers the entire rotating current collector 42 to prevent the foreign matter from dropping and adhering to the rotating current collector 42 so that the electrical contact state with the current collecting rail 41 is always stable. By seeing through the transparent cover 46, visual inspection of the worn state of the rotating current collector 41 and the dirty state of the upper surface of the current collecting rail 41 can be facilitated.
[0021]
As shown in FIG. 1, when the rotating support 10, the camera 20, and the cage lightning arrester 30 are continuously rotated integrally at the height of the upper end of the column 50, the relative positions of the camera 20 and the lightning arrester 30 are continuously rotated without changing. No part of the lightning arrester 30 enters the field of view of the camera 20. Therefore, a lightning rod image (lightning arrester image) is not captured in images continuously captured by the camera 20, and accurate monitoring, observation, and the like of the environment captured from this image can be performed. Further, since the camera 20 at a high place is always surrounded by the lightning arrester 30 in a constant form, and the rotating lightning arrester 30 is always grounded in a stable state via the current collector 40, the camera 20 is always stable from lightning strikes. Protected by state.
[0022]
Note that the present invention is not limited to the environment photographing apparatus installed at an outdoor high place, but is also effectively applied to an environment photographing apparatus or the like installed at a low place where lightning may occur.
[0023]
【The invention's effect】
According to the first aspect of the present invention, since the camera and the lightning protection means are continuously rotated without changing the relative position by the continuous rotation of the rotating support, the camera can be viewed at any rotation angle of the continuously rotating camera. There is no lightning protection means, so the image of the lightning protection means is not reflected in the image taken by the camera, and the camera image can be accurately monitored without being disturbed by the lightning protection means image. Can improve reliability.
[0024]
According to the invention of claim 2, since the cage lightning arrester surrounding the camera protects the camera against lightning strikes from the front, rear, right and left of the camera and from above, a highly reliable environmental photographing with an excellent protection function against the lightning strike of the camera. A device can be provided.
[0025]
According to the third aspect of the present invention, the grounding state of the rotating lightning protection means is stabilized through the current collector, and the function of protecting the camera of the lightning protection means from lightning is always ensured stably.
[0026]
According to the invention of claim 4, since the upper surface of the current collecting rail that is a fixed current collector of the current collecting device is covered with the protective cover, there is a concern that bird droppings or the like may fall and adhere on the current collecting rail. Therefore, the electrical contact between the current collector rail and the rotating current collector is always stable, the current collector becomes more reliable, and the current collector is easily maintained.
