【発明の属する技術分野】
この発明は、透水性を有する舗装面の透水孔の空隙に詰まった土砂や塵埃等を除去するに際して使用した水を掃除用空間に形成した水吸引部に集中せしめるようにした透水性舗装用掃除装置に関するものである。
【0002】
【従来の技術】
透水性を有する舗装とは、降雨水が透過することができる多数の透水孔を表層に形成した舗装を言い、基本的には雨天時の一般車輛の走行安全性確保のためにハイドロプレニング現象やスモーキング現象の抑止効果を有すると同時に、タイヤ等から発生する騒音の低減効果を有し、また降雨水の地下還元機能を付与することを目的とするものであるが、他に地下水のかん養、河川や下水道に流入する雨水の流量の抑制又は歩行性の向上等も目的とされている。したがって前記透水孔は、常時、その機能を維持することができる状態、すなわち透水性を有していなければならないところ、歩行、車輛走行又は風等の影響によって土砂又は塵埃等が前記透水孔に詰まり、経年的にその機能の低下又は喪失を招来することになり、このことは大きな現実的問題となっているところである。
【0003】
そのためには、前記舗装面の透水孔に目詰まりした前記土砂等を何らかの方法で除去しなければならない。
【0004】
このように除去する方法として従来から水を用いることが一般に行われている。すなわち、前記水を舗装面に向けて噴水せしめ、この水による水圧によって前記舗装面の透水孔に目詰まりした土砂等を洗掘浮上させ、このように土砂等が混合した水を回収することによって前記土砂等を除去しようという方法である。
【0005】
そのための具体的な装置としては、適宜な濾過装置を具備した給水兼散水回収タンク(濾過装置を具備した散水回収ノズルと給水タンクとを別体により構成し、これをパイプで連結する場合もある。)及びブロアーを車輛に搭載するとともに、前記給水兼散水回収タンクにパイプを介して連結した散水ノズルを舗装面に向けて前記車輛下面に配設するとともに、前記タンクにパイプを介して連結した散水回収用ノズルを前記散水ノズルの車輛進行方向の後方又は前後方で、舗装面に向けて車輛下面に配設されていた。
【0006】
そしてこの散水回収用ノズルは、前記タンクを経由してブロアーの吸引側に連結することにより、このブロアーの吸引力を利用して水を前記タンク内に回収するように構成するとともに、前記散水回収用ノズルの進行方向前方を除く周囲を舗装面に接するゴム板によって覆うように構成していたのである。
【0007】
また前記ゴム板を用いずにブロアーに送気パイプを介して連結した空気噴出ノズルを配設し、この空気によって水、したがって溶解した土砂等が掃除用空間から外部に散逸することを防止するものも存在した。
【0008】
その結果、この掃除用車輛を走行せしめながら、前記給水兼散水回収タンク内の水を散水ノズルによって舗装面に散水し、この散水によって透水孔から浮上した土砂等を含む水を回収ノズルによって同タンク(給水タンクと散水回収タンクが別体で構成されている場合は散水回収タンク)に回収して、この回収された水は濾過作用を受けて再度散水用として用いられていたのである。
【0009】
また前記散水ノズルを配設した送水パイプは、掃除用車輛に対し着脱可能に配設されてはいたものの、その着脱の方向は上下方向への移動を伴う構造になっていたのであった。
【0010】
【発明が解決しようとする課題】
ところが、前記した従来例にあっては、舗装面の透水孔に目詰まりした土砂等は、散水の水圧によって掘り起こされ、これを風圧によって回収することになるため、この溶解浮上には少なからざる時間を要しており、そのために車輛の走行速度を高めることができず、一日の作業量は非常に短距離又は狭面積となっており、はなはだ非能率的であった。
【0011】
また掃除用車輛の進行方向前方及び両側下面が開放されているため、これが傾斜している舗装面にあっては、前記散水した水が散水回収ノズルによって回収される前に、前記開放部から流失することになり水の無駄が生じるのみならず、確実な回収を行うことができなかった。
【0012】
さらに散水及び洗掘等が順調に行われた場合において、散水回収用ノズルの直近には前記ゴム板が存在し、このゴム板により外気との遮蔽がなされるために、このゴム板の近傍で水を回収する際にブロアーの吸引力に大きな負荷が掛かり、前記吸引力が弱められることにもなっていた。また舗装面には細かな凹凸が存在するところ、前記ゴム板は前記車輛下面への散水を集めるために使用するものであるから舗装面に強固に押し付ける必要があり、その結果、車輛の走行速度を極端にゆるやかなものにしなければならず、このことも作業量の減少となっていたのであった。
【0013】
また前記ゴム板は、車輛の進行方向に対して直角をなしているため、この車輛が進行方向を変更する場合(例えばコーナーを走行する場合)には、前記ゴム板が舗装面に対して抵抗となるのみならず、経時的に摩耗してしまうことにもなっていたのである。
【0014】
一方、前記のように空気噴出ノズルを配設したものにあっては、この空気が一種の壁を形成して解放部から外部に流出を防止することが目的ではあったが、現実には、それは十分になし得ず、しかし仮になし得たとしても、この空気の壁は単なるエアカーテンの役割を果たすのみであるから、このエアカーテンによって囲まれた空間内の水を回収用ノズルまで導くための時間が長く要することも問題として指摘されていた。
【0015】
さらにこの散水ノズルから出る水は、基本的には真水を用いるが、前記のように散水ノズルからでた水を回収し、これを散水用に用いることが行われているところ、この回収した水は、一応濾過装置を経由せしめてはいるものの、十分な濾過が行われないのが一般で、したがって前記散水ノズルは土砂等による目詰まり、又は土砂等によって摩耗が生じるために、送水パイプごと取り外し、修理、交換、点検を適当時期に行う必要があったが、前記のように送水パイプの着脱を上下方向に行わなければならないため、その取り外し及び取り付け作業が煩雑であった。
【0016】
【課題を解決するための手段】
そこでこの発明に係る透水性舗装面用掃除装置の送気装置(請求項1)は前記の課題を解決するために、車輛下面に形成される掃除用空間に、舗装面に向けた送水装置及び送気装置を設けた透水性舗装面用掃除装置において、送気装置の一部を構成する送気パイプを、前記車輛の進行方向に直交する状態に配設するとともに、この送気パイプに複数の空気噴出ノズルを直線状かつ所望間隔で配設し、この空気噴出ノズルの空気出口を直線状のスリットに形成し、前記送気パイプの長手方向中央部分に位置する空気噴出ノズルの空気出口は水平の横一直線に形成するとともに、前記掃除用車輛の進行方向前方に配設する空気噴出ノズルのスリット状の空気出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい反時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成し、また掃除用車輛の進行方向後方に配設する空気噴出ノズルのスリット状の空気出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成したものである。
【0017】
またこの発明に係る透水性舗装面用掃除装置(請求項2)は前記の課題を解決するために、車輛下面に形成される掃除用空間に、舗装面に向けた送水装置及び送気装置を設けた透水性舗装面用掃除装置において、送水装置の一部を構成する送水パイプを、前記車輛の進行方向に直交する状態に配設するとともに、この送水パイプに複数の散水ノズルを直線状かつ所望間隔で配設し、この散水ノズルの散水出口を直線状のスリットに形成し、前記送水パイプの長手方向中央部分に位置する散水ノズルの散水出口は水平の横一直線に形成するとともに、前記掃除用車輛の進行方向前方に配設する散水ノズルのスリット状の散水出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい反時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成し、また掃除用車輛の進行方向後方に配設する散水ノズルのスリット状の散水出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成したものである。
【0018】
さらこの発明に係る透水性舗装面用掃除装置(請求項3)は前記の課題を解決するために、車輛下面に形成される掃除用空間に、舗装面に向けた散水ノズル及び送気装置を設けた透水性舗装面用掃除装置において、
送気装置の一部を構成する送気パイプを、前記車輛の進行方向に直交する状態に配設するとともに、この送気パイプに複数の空気噴出ノズルを直線状かつ所望間隔で配設し、この空気噴出ノズルの空気出口を直線状のスリットに形成し、前記送気パイプの長手方向中央部分に位置する空気噴出ノズルの空気出口は水平の横一直線に形成するとともに、前記掃除用車輛の進行方向前方に配設する空気噴出ノズルのスリット状の空気出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい反時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成し、また掃除用車輛の進行方向後方に配設する空気噴出ノズルのスリット状の空気出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成し、
前記送水装置の一部を構成する送水パイプを、前記車輛の進行方向に直交する状態に配設するとともに、この送水パイプに複数の散水ノズルを直線状かつ所望間隔で配設し、この散水ノズルの散水出口を直線状のスリットに形成し、前記送水パイプの長手方向中央部分に位置する散水ノズルの散水出口は水平の横一直線に形成するとともに、前記掃除用車輛の進行方向前方に配設する散水ノズルのスリット状の散水出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい反時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成し、また掃除用車輛の進行方向後方に配設する散水ノズルのスリット状の散水出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成したものである。
【0020】
さらにこの発明に係る透水性舗装面用掃除装置(請求項)は前記の課題を解決するために、前記散水ノズルから散水される水の軸線及び空気噴出ノズルから出る空気の軸線が掃除用空間の反外側に向けた斜めの角度となるように前記散水ノズル及び空気噴出ノズルを配設するとともに、前記両軸線に平行するように制御板を配設したものである。
【0023】
【発明の実施の形態】
次にこの発明に係る透水性舗装面用掃除装置の実施の形態を図面に基づいて述べると、1は複数の空気噴出ノズル2を配設した送気パイプであり、前記空気噴出ノズル2には直線状のスリット状の空気出口3を形成してある。
【0024】
そして前記送気パイプ1は掃除装置を搭載した車輛(図示せず)に別途搭載したブロアー(図示せず)に連結されているとともに、前記車輛下面に形成される掃除用空間Sにおいて、掃除用車輛の進行方向前後に、間隔をおいて直交するように、すなわち横向きに配設されている。
【0025】
また前記直線状のスリット状空気出口3は、前記送気パイプ1のうち、掃除用車輛の進行方向中央部に位置するものにあっては横一直線に形成し、右に遠ざかるにしたがい時計方向に順次角度を変えつつ、最も遠い位置に存在する空気出口3が縦一直線前の角度に形成してあり、一方、中央より左に遠ざかるにしたがい反時計方向に角度を変えつつ最も遠い位置に存在する空気出口3は縦一直線前の角度に形成してある。
【0026】
また掃除用車輛の進行方向後方に配設する送気パイプ1の空気出口3は、送気パイプ1の中央に位置するものにあっては横一直線に形成し、右に遠ざかるにしたがい反時計方向に順次角度を変えつつ、最も遠い位置に存在する空気出口3を縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい時計方向に順次角度を変えつつ、最も遠い位置に存在する空気出口3を縦一直線前の角度に形成するのである。
【0027】
以上の内容は、掃除用車輛の進行方向前方及び後方の空気噴出ノズル2又はその中央位置から左右に配設される空気出口3の角度が必ずしも対称でなければならないことを意味するものではなく、しかし対称であってもよいことを意味するものである。
【0028】
5は複数の散水ノズル6を配設した送水パイプであり、前記散水ノズル6には直線状のスリット状の散水出口7を形成してある。
【0029】
そして前記送水パイプ5は掃除装置を搭載した車輛(図示せず)に別途搭載した貯水タンク(図示せず)に連結されているとともに、前記車輛下面に形成される掃除用空間Sにおいて、掃除用車輛の進行方向前後に、間隔をおいて直交するように、すなわち横向きに配設されている。
【0030】
また前記直線状のスリット状散水出口7は、前記送水パイプ5のうち、掃除用車輛の進行方向中央部に位置するものにあっては横一直線に形成し、右に遠ざかるにしたがい時計方向に順次角度を変えつつ、最も遠い位置に存在する空気出口3が縦一直線前の角度に形成してあり、一方、中央より左に遠ざかるにしたがい反時計方向に角度を変えつつ最も遠い位置に存在する散水出口7は縦一直線前の角度に形成してある。
【0031】
また掃除用車輛の進行方向後方に配設する送水パイプ5の散水出口7は、送水パイプ5の中央に位置するものにあっては横一直線に形成し、右に遠ざかるにしたがい反時計方向に順次角度を変えつつ、最も遠い位置に存在する空気出口3を縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい時計方向に順次角度を変えつつ、最も遠い位置に存在する散水出口7を縦一直線前の角度に形成するのである。
【0032】
以上の内容は、掃除用車輛の進行方向前方及び後方の散水ノズル6又はその中央位置から左右に配設される散水出口7の角度が必ずしも対称でなければならないことを意味するものではなく、しかし対称であってもよいことを意味するものである。
【0033】
しかして前記空気噴出ノズル2から噴出する空気は、スリット状の空気出口3から出るとあたかも扇状に拡がり、したがってすべての空気出口3から出る空気が連続した壁状を呈することになる。一方、散水ノズル6から出る散水も、スリット状散水出口7から出ると、あたかも扇状に広がる。
【0034】
また空気出口3の及び散水出口7の形成角度を前記のように形成してあるので、すべての空気出口3から出るすべての空気の壁とすべての散水出口7から出る散水の壁は並行し、散水出口7から舗装面に出る水は、前記掃除用空間Sの内部方向に風圧によって導かれることになる。すなわち空気出口3の角度をして空気出口3から出る空気を全体的に集合せしめることになるのである。しかし集合せしめるとは称しても、一点に集合せしめるのではなく、掃除用空間Sの内部方向に集合せしめるという意味である。
【0035】
したがって本発明者らの実験によると、この発明に係る送気装置の送気パイプ1を掃除用車輛の進行方向前後方にのみ配設し、両側方に配設せずとも、掃除用の散水が両側に流出することがなかった。しかし掃除用空間Sの両側にも空気噴出ノズル2付きの送気パイプ1を配設し、又はこれに代えてゴム板を配設してもかまわない。
【0036】
尚、前記のように空気出口から噴出する空気によって導かれ、散水回収部4によって吸引され、図示しない散水回収タンクに送られるのである。
【0037】
図4及び図5に示す8は、前記散水ノズル6及び空気噴出ノズル2の間に、これらを仕切るように配設した制御板である。この制御板8は、例えば図4に示すようにその下端が舗装面に接しない状態、すなわち適度な空間をもって配設されてる場合もあるが、図5に示すように、制御板8の静止の状態にあってはその下端が舗装面に接するが、空気噴出ノズル2から出る風圧によって、その下端が押され、舗装面との間に事実上の空隙が形成されるのである。
【0038】
したがって散水ノズル6から水を、また空気噴出ノズル2から空気を放出すると、散水回収ノズル8から出た水が舗装面に達した後に前記空気噴出ノズル2から出る空気によって風圧が作用する(空気は制御板8の下端の空隙をくぐり抜け水に風圧をかけるため)ことになるので、水による舗装面の掃除に悪影響を来さないことになるのみならず、水の流動を規制することになるので、散水回収ノズル8に有効に導くことにもなるのである。
【0039】
上記の作用をより効率的に行うためには、図に示すように、散水ノズル6から出る水の軸線n、空気噴出ノズル2から出る空気の軸線n’が、掃除用空間Sの反外側となるように前記散水ノズル6及び空気噴出ノズル2を傾かせ、かつ制御板8をこれらに平行するように配設することが好ましい。
【0040】
図6に示す9は、掃除用空間Sにおいて掃除用車輛の下面に配設したフレームであり、このフレーム9に散水ノズル6を設けた送水パイプ5を配設(場合によっては空気噴出ノズル2に設けた送気パイプ1も配設する。)してある。そしてこの場合、送水パイプ5をスライド自在かつ収納可能な溝状スペース10を有するように前記フレーム9を形成し、この溝状スペース10内に前記送水パイプ5を箪笥の引き出し状に収納するのである。
【0041】
この結果、送水パイプ5をフレーム9の溝状スペース10内をスライドさせながら横方向に引き出すことができ、送水パイプ5の修理、点検、交換等、その管理が容易になるのである。
【0044】
【発明の効果】
前記のようにこの発明に係る透水性舗装面用掃除装置(請求項1)によれば、車輛下面に形成される掃除用空間に、舗装面に向けた送水装置及び送気装置を設けた透水性舗装面用掃除装置において、送気装置の一部を構成する送気パイプを、前記車輛の進行方向に直交する状態に配設するとともに、この送気パイプに複数の空気噴出ノズルを直線状かつ所望間隔で配設し、この空気噴出ノズルの空気出口を直線状のスリットに形成し、前記送気パイプの長手方向中央部分に位置する空気噴出ノズルの空気出口は水平の横一直線に形成するとともに、前記掃除用車輛の進行方向前方に配設する空気噴出ノズルのスリット状の空気出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい反時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成し、また掃除用車輛の進行方向後方に配設する空気噴出ノズルのスリット状の空気出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する空気出口は縦一直線前の角度に形成してあるので、
散水ノズルからで出る水を掃除用空間、すなわち散水吸引部方向に導くことができ、かつ空気噴出ノズル群を配設した送気パイプを、掃除用車輛の進行方向前後にのみ設けることで十分であり、したがってその数を減らすことができるという効果を有するのである。
【0045】
またこの発明に係る透水性舗装面用掃除装置(請求項2)によれば、車輛下面に形成される掃除用空間に、舗装面に向けた送水装置及び送気装置を設けた透水性舗装面用掃除装置において、送水装置の一部を構成する送水パイプを、前記車輛の進行方向に直交する状態に配設するとともに、この送水パイプに複数の散水ノズルを直線状かつ所望間隔で配設し、この散水ノズルの散水出口を直線状のスリットに形成し、前記送水パイプの長手方向中央部分に位置する散水ノズルの散水出口は水平の横一直線に形成するとともに、前記掃除用車輛の進行方向前方に配設する散水ノズルのスリット状の散水出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい反時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成し、また掃除用車輛の進行方向後方に配設する散水ノズルのスリット状の散水出口は中央より右に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成し、一方、中央より左に遠ざかるにしたがい時計方向に角度を変えつつ最も遠い位置に存在する散水出口は縦一直線前の角度に形成してあるので、
散水ノズルに形成した散水出口の形状をして、散水ノズルから出る散水が全体的に弓形形状の壁を構成し、したがって散水同士のもたれ合いによって掃除用空間部、すなわち散水吸引部方向に導くことができるという効果を有するのである。
【0046】
さらこの発明に係る透水性舗装面用掃除装置(請求項3)によれば、
車輛下面に形成される掃除用空間に、舗装面に向けた散水ノズル及び送気装置を設けた透水性舗装面用掃除装置において、

前記制御板をして散水ノズルから出た水に対して不慮の不必要な風圧を加えることなく、しかもこの水が舗装面に達した時点で風圧を作用させることができ、したがって舗装面の透水孔の土砂等を有効に除去させることができるという効果を有するのである。

BACKGROUND OF THE INVENTION
The present invention relates to a water-permeable pavement cleaning in which water used for removing dirt and dust clogged in a water-permeable hole in a water-permeable pavement surface is concentrated in a water suction portion formed in a cleaning space. It relates to the device.
[0002]
[Prior art]
Permeable pavement is a pavement that has a large number of water permeable holes that allow rainwater to permeate on its surface. Basically, it is a hydroplaning phenomenon to ensure the safety of ordinary vehicles when it rains. It has the effect of suppressing smoking and smoking phenomenon, and at the same time has the effect of reducing the noise generated from tires, etc. It is also aimed at reducing the flow of rainwater flowing into rivers and sewers or improving walking. Therefore, the water-permeable hole must always be able to maintain its function, that is, it must have water permeability. However, dirt, dust, or the like is clogged in the water-permeable hole due to walking, vehicle running, or wind. This will cause deterioration or loss of its function over time, and this is a big practical problem.
[0003]
For that purpose, the earth and sand clogged in the water-permeable holes of the pavement surface must be removed by some method.
[0004]
In general, water has been conventionally used as a method for removing in this manner. That is, by causing the water to fountain toward the pavement surface, scouring and floating the earth and sand clogged in the water-permeable holes of the pavement surface by the water pressure by the water, and collecting the water mixed with the earth and sand in this way This is a method for removing the earth and sand.
[0005]
As a specific device for that purpose, there is a case where a water supply / water sprinkling recovery tank equipped with an appropriate filtration device (a water sprinkling recovery nozzle equipped with a filtration device and a water supply tank are formed separately and connected by a pipe). .) And a blower mounted on the vehicle, and a watering nozzle connected to the water supply / watering recovery tank via a pipe is arranged on the lower surface of the vehicle toward the pavement surface and connected to the tank via a pipe. The nozzle for watering collection was arrange | positioned on the vehicle lower surface toward the pavement surface in the back or front back of the vehicle traveling direction of the watering nozzle.
[0006]
The sprinkling recovery nozzle is connected to the suction side of the blower via the tank so as to recover water into the tank by using the suction force of the blower. The periphery excluding the front of the nozzle in the direction of travel was covered with a rubber plate in contact with the pavement surface.
[0007]
Also, an air ejection nozzle connected to the blower via an air supply pipe without using the rubber plate is provided, and this air prevents water, and hence dissolved earth and sand, from escaping from the cleaning space to the outside. There was also.
[0008]
As a result, while running this cleaning vehicle, the water in the water supply / sprinkling recovery tank is sprinkled on the pavement surface by the watering nozzle, and the water containing earth and sand floating from the water transmission hole by the watering is recovered by the recovery nozzle. (The water supply tank and the sprinkling recovery tank are collected separately) and the recovered water was filtered and used again for sprinkling.
[0009]
Moreover, although the water supply pipe provided with the watering nozzle was detachably provided with respect to the cleaning vehicle, the attachment / detachment direction had a structure accompanied by movement in the vertical direction.
[0010]
[Problems to be solved by the invention]
However, in the above-mentioned conventional example, the earth and sand clogged in the water-permeable holes on the pavement surface are dug up by the water pressure of the water spray, and this is recovered by the wind pressure. Therefore, the traveling speed of the vehicle cannot be increased, and the daily work amount is very short distance or narrow area, which is very inefficient.
[0011]
Further, since the front and both lower surfaces of the cleaning vehicle are opened in the direction of the pavement, the sprinkled water is washed away from the open portion before being collected by the water collection nozzle. As a result, not only water wasted, but also reliable recovery could not be performed.
[0012]
Furthermore, when watering, scouring, etc. are performed smoothly, the rubber plate exists in the immediate vicinity of the nozzle for watering recovery, and this rubber plate is shielded from the outside air. When collecting water, a large load is applied to the suction force of the blower, and the suction force is weakened. Also, there are fine irregularities on the pavement surface, so the rubber plate is used to collect water spray on the lower surface of the vehicle, so it is necessary to press firmly on the pavement surface. Had to be extremely loose, which also reduced the amount of work.
[0013]
Further, since the rubber plate is perpendicular to the traveling direction of the vehicle, when the vehicle changes its traveling direction (for example, when traveling in a corner), the rubber plate resists the pavement surface. In addition to this, it was supposed to wear over time.
[0014]
On the other hand, in the case where the air ejection nozzle is disposed as described above, the purpose of this air is to form a kind of wall and prevent the air from flowing out from the release portion. Even if it can not be done sufficiently, this air wall only serves as an air curtain, so that the water in the space surrounded by the air curtain is guided to the recovery nozzle. It has been pointed out that it takes a long time.
[0015]
Furthermore, fresh water is basically used as the water discharged from the watering nozzle. However, as described above, the water discharged from the watering nozzle is collected and used for watering. In general, although it is passed through a filtration device, it is generally not sufficiently filtered. Therefore, the watering nozzle is clogged with earth or sand, or wear due to earth or sand, so that the water pipe is removed. However, it was necessary to carry out repairs, replacements, and inspections at appropriate times. However, since the water pipes had to be attached and detached in the vertical direction as described above, the removal and attachment work was complicated.
[0016]

DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a water-permeable pavement surface cleaning device according to the present invention will be described with reference to the drawings. Reference numeral 1 denotes an air supply pipe provided with a plurality of air ejection nozzles 2. A straight slit-shaped air outlet 3 is formed.
[0024]
The air supply pipe 1 is connected to a blower (not shown) separately mounted on a vehicle (not shown) on which a cleaning device is mounted, and is used for cleaning in a cleaning space S formed on the lower surface of the vehicle. Before and after the traveling direction of the vehicle, the vehicle is arranged so as to be orthogonal to each other with an interval, that is, horizontally.
[0025]
Further, the straight slit-like air outlet 3 is formed in a horizontal straight line in the air-feeding pipe 1 that is located in the central portion of the cleaning vehicle in the traveling direction, and clockwise as it moves away to the right. The air outlet 3 that exists at the farthest position while changing the angle sequentially is formed at the angle in front of the vertical straight line, while it is located at the farthest position while changing the angle in the counterclockwise direction as it moves to the left from the center. The air outlet 3 is formed at an angle before the vertical straight line.
[0026]
In addition, the air outlet 3 of the air supply pipe 1 disposed behind the cleaning vehicle in the traveling direction is formed in a horizontal straight line in the case of the one located in the center of the air supply pipe 1 and counterclockwise as it moves away to the right. The air outlet 3 present at the farthest position is formed at an angle in front of a straight line while sequentially changing the angle to the left, while it is present at the farthest position while changing the angle sequentially in the clockwise direction as it moves to the left from the center. The air outlet 3 is formed at an angle before the vertical straight line.
[0027]
The above content does not mean that the angle of the air outlet nozzles 2 arranged on the left and right sides of the front and rear air jet nozzles 2 or the center position thereof in the traveling direction of the cleaning vehicle must be symmetrical, However, it means that it may be symmetric.
[0028]
Reference numeral 5 denotes a water supply pipe provided with a plurality of watering nozzles 6, and the watering nozzles 6 are formed with straight slit-like watering outlets 7.
[0029]
The water supply pipe 5 is connected to a water storage tank (not shown) separately mounted on a vehicle (not shown) on which a cleaning device is mounted, and in the cleaning space S formed on the lower surface of the vehicle, Before and after the traveling direction of the vehicle, the vehicle is arranged so as to be orthogonal to each other with an interval, that is, horizontally.
[0030]
Further, the straight slit-shaped sprinkling outlet 7 is formed in a horizontal straight line in the water supply pipe 5 that is located in the central portion in the traveling direction of the cleaning vehicle, and sequentially in the clockwise direction as it moves away to the right. While changing the angle, the air outlet 3 present at the farthest position is formed at the angle in front of the vertical straight line, and on the other hand, the water sprinkling present at the farthest position while changing the angle in the counterclockwise direction as moving away from the center to the left. The outlet 7 is formed at an angle before the vertical straight line.
[0031]
Further, the sprinkling outlet 7 of the water supply pipe 5 disposed behind the cleaning vehicle in the traveling direction is formed in a horizontal straight line in the case of the one located in the center of the water supply pipe 5 and sequentially counterclockwise as moving away to the right. While changing the angle, the air outlet 3 present at the farthest position is formed at an angle in front of the vertical straight line, while the water outlet is located at the farthest position while changing the angle sequentially in the clockwise direction as it moves further left from the center. 7 is formed at an angle before the vertical straight line.
[0032]
The above content does not mean that the angle of the watering nozzles 6 disposed in the front and rear of the cleaning vehicle or the watering outlets 7 disposed on the left and right from the central position must be symmetrical, but It means that it may be symmetric.
[0033]
Thus, when the air ejected from the air ejection nozzle 2 exits from the slit-shaped air outlet 3, it spreads as if it is a fan, so that the air exiting from all the air outlets 3 has a continuous wall shape. On the other hand, the water sprinkled from the sprinkling nozzle 6 also spreads out like a fan when it comes out of the slit sprinkling outlet 7.
[0034]
In addition, since the formation angles of the air outlet 3 and the sprinkling outlet 7 are formed as described above, the walls of all the air exiting from all the air outlets 3 and the walls of the sprinkling exiting from all the sprinkling outlets 7 are parallel. The water coming out of the sprinkling outlet 7 to the pavement surface is guided by the wind pressure toward the inside of the cleaning space S. That is, the air that exits from the air outlet 3 is gathered as a whole at an angle of the air outlet 3. However, even if it says, it means that it is not assembled in one point but in the internal direction of the cleaning space S.
[0035]
Therefore, according to the experiments by the present inventors, the air supply pipe 1 of the air supply device according to the present invention is disposed only in front and rear in the traveling direction of the cleaning vehicle, and it is not necessary to dispose it on both sides. Never flowed out on both sides. However, the air supply pipe 1 with the air ejection nozzle 2 may be disposed on both sides of the cleaning space S, or a rubber plate may be disposed in place of this.
[0036]
In addition, it guide | induces by the air which blows out from an air exit as mentioned above, is attracted | sucked by the sprinkling recovery part 4, and is sent to the sprinkling recovery tank which is not shown in figure.
[0037]
Reference numeral 8 shown in FIGS. 4 and 5 is a control plate disposed between the watering nozzle 6 and the air ejection nozzle 2 so as to partition them. For example, as shown in FIG. 4, the lower end of the control plate 8 may not be in contact with the pavement surface, that is, the control plate 8 may be disposed with an appropriate space. However, as shown in FIG. In the state, the lower end is in contact with the pavement surface, but the lower end is pushed by the wind pressure emitted from the air jet nozzle 2, and a practical gap is formed between the pavement surface.
[0038]
Therefore, when water is discharged from the water spray nozzle 6 and air is discharged from the air jet nozzle 2, the wind pressure acts on the air from the air jet nozzle 2 after the water from the water spray nozzle 8 reaches the pavement surface (air is Because it passes through the gap at the lower end of the control plate 8 and applies wind pressure to the water), not only will it not adversely affect the cleaning of the pavement surface with water, but also it will regulate the flow of water. In other words, the water is effectively guided to the water spray recovery nozzle 8.
[0039]
In order to perform the above action more efficiently, as shown in FIG. 4 , the axis n of the water exiting from the water spray nozzle 6 and the axis n ′ of the air exiting from the air ejection nozzle 2 are outside the cleaning space S. It is preferable that the watering nozzle 6 and the air ejection nozzle 2 are inclined so that the control plate 8 is parallel to them.
[0040]
6 shown in FIG. 6 is a frame provided on the lower surface of the cleaning vehicle in the cleaning space S, and a water supply pipe 5 provided with a water spray nozzle 6 is provided on the frame 9 (in some cases, the air jet nozzle 2 is provided with The provided air supply pipe 1 is also provided.). In this case, the frame 9 is formed so as to have a groove-like space 10 in which the water-feeding pipe 5 can be slidably accommodated, and the water-feeding pipe 5 is housed in the groove-like space 10 in the shape of a drawer. .
[0041]
As a result, the water supply pipe 5 can be pulled out in the lateral direction while sliding in the groove-like space 10 of the frame 9, and the management, such as repair, inspection, and replacement of the water supply pipe 5, becomes easy.
[0044]
【The invention's effect】
As described above, according to the water-permeable pavement surface cleaning device according to the present invention (Claim 1), the water-permeable device provided with the water supply device and the air supply device directed toward the pavement surface in the cleaning space formed on the lower surface of the vehicle. In the cleaning device for pavement surfaces, an air supply pipe constituting a part of the air supply device is arranged in a state orthogonal to the traveling direction of the vehicle, and a plurality of air ejection nozzles are linearly formed on the air supply pipe. The air outlet of the air ejection nozzle is formed in a linear slit, and the air outlet of the air ejection nozzle located in the longitudinal center portion of the air supply pipe is formed in a horizontal horizontal straight line. In addition, the slit-like air outlet of the air ejection nozzle disposed in front of the cleaning vehicle in the traveling direction changes the clockwise direction as the distance from the center increases, and the air outlet located at the farthest position is in front of a straight line. of On the other hand, the air outlet located at the farthest position while changing the angle in the counterclockwise direction as it moves farther to the left than the center is formed at an angle that is in front of the vertical line, and is arranged behind the cleaning vehicle in the traveling direction. The slit-like air outlet of the air ejection nozzle to be installed changes the angle in the clockwise direction as it moves farther to the right from the center, while the air outlet that exists at the farthest position is formed at an angle in front of the vertical straight line, while on the left from the center Since the air outlet that exists at the farthest position while changing the angle in the clockwise direction as it moves away is formed at the angle in front of the vertical line,
It is sufficient to provide air supply pipes that can guide the water coming out of the watering nozzle in the direction of the cleaning space, i.e., the watering suction part, and that are provided with the air jet nozzle group only before and after the traveling direction of the cleaning vehicle. Therefore, the number can be reduced.
[0045]

In the cleaning device, a water supply pipe constituting a part of the water supply device is arranged in a state orthogonal to the traveling direction of the vehicle, and a plurality of water spray nozzles are arranged linearly at desired intervals on the water supply pipe. The watering outlet of the watering nozzle is formed in a linear slit, and the watering outlet of the watering nozzle located in the longitudinal center portion of the water supply pipe is formed in a horizontal horizontal straight line, and the front of the cleaning vehicle in the traveling direction. As the slit-shaped water outlet of the water nozzle is located farther to the right than the center, the water outlet is located at the farthest position while changing the angle in the clockwise direction. The water outlet located at the farthest position while changing the angle in the counterclockwise direction as it moves further left is formed at the angle in front of the vertical line, and the slit-shaped nozzle of the water nozzle arranged behind the cleaning vehicle in the traveling direction. The water outlet is located at the farthest position while changing the angle in the clockwise direction as it moves away from the center to the right, while the angle is changed in the clockwise direction as it moves away from the center to the left. However, since the sprinkling outlet that is located at the farthest position is formed at an angle in front of the vertical straight line,
The shape of the watering outlet formed in the watering nozzle, the watering from the watering nozzle constitutes an overall arcuate wall, and therefore it can be guided toward the cleaning space, i.e., the watering suction part by the backlash of the watering. It has the effect of being able to do it.
[0046]
Furthermore, according to the cleaning device for permeable pavement surfaces according to the present invention (Claim 3),
In the water-permeable pavement cleaning device provided with a watering nozzle and an air supply device directed to the pavement surface in the cleaning space formed on the lower surface of the vehicle,
An air supply pipe constituting a part of the air supply device is arranged in a state orthogonal to the traveling direction of the vehicle, and a plurality of air ejection nozzles are arranged linearly at desired intervals in the air supply pipe, The air outlet of the air ejection nozzle is formed in a straight slit, and the air outlet of the air ejection nozzle located in the longitudinal center portion of the air supply pipe is formed in a horizontal horizontal line, and the progress of the cleaning vehicle The air outlet located at the farthest position while changing the angle in the clockwise direction as the slit-like air outlet of the air ejection nozzle disposed forward in the direction changes to the right from the center, is formed at an angle before the vertical straight line, The air outlet located at the farthest position while changing the angle in the counterclockwise direction as it moves to the left from the center is formed at an angle in front of the vertical straight line, and an air jet arranged behind the cleaning vehicle in the traveling direction. The slit-shaped air outlet of the nozzle changes the angle in the clockwise direction as it moves away from the center, and the air outlet located at the farthest position is formed at the angle in front of the vertical line, while the clock as it moves away from the center to the left. The air outlet that exists at the farthest position while changing the angle in the direction is formed at the angle before the vertical straight line,
A water supply pipe constituting a part of the water supply device is arranged in a state orthogonal to the traveling direction of the vehicle, and a plurality of watering nozzles are arranged linearly at desired intervals on the water supply pipe. The sprinkling outlet is formed in a straight slit, and the sprinkling outlet of the sprinkling nozzle located at the center in the longitudinal direction of the water supply pipe is formed in a horizontal horizontal straight line and disposed in front of the traveling direction of the cleaning vehicle. As the water outlet of the nozzle of the water spray nozzle moves to the right from the center, the water outlet located at the farthest position while changing the angle in the clockwise direction is formed at an angle in front of the vertical line, while as it moves away from the center to the left. The sprinkler outlet located at the farthest position while changing the angle in the counterclockwise direction is formed at an angle in front of the vertical straight line, and a water spray nozzle slip disposed behind the cleaning vehicle in the traveling direction. The water spout is located at the farthest position while changing the angle in the clockwise direction as it moves away from the center to the right. Since the sprinkling outlet that exists at the farthest position while changing the angle is formed at an angle before the vertical straight line,
It is sufficient to provide air supply pipes that can guide the water coming out of the watering nozzle in the direction of the cleaning space, i.e., the watering suction part, and that are provided with the air jet nozzle group only before and after the traveling direction of the cleaning vehicle. Therefore, the number can be reduced and the shape of the sprinkling outlet formed in the watering nozzle, the watering from the watering nozzle forms an overall arcuate wall, and therefore cleaning by the backlash between the watering This has the effect that the empty space can be guided in the direction of the sprinkling suction portion.
[0047]
Moreover, according to the water-permeable pavement surface cleaning device according to the present invention (Claim 4), the water-permeable pavement surface provided with a watering nozzle and an air supply device directed toward the pavement surface in a cleaning space formed on the lower surface of the vehicle. In the cleaning device for cleaning, the water spray nozzle and the air ejection nozzle are arranged so that the axis of water sprayed from the water spray nozzle and the axis of the air discharged from the air ejection nozzle are at an oblique angle toward the opposite side of the cleaning space. In addition, since the control plate is arranged so as to be parallel to the two axes,
The air pressure can be applied when the water reaches the pavement surface without inadvertently applying unnecessary wind pressure to the water discharged from the watering nozzle by using the control plate, and thus the water permeability of the pavement surface can be applied. It has the effect that the earth and sand etc. of a hole can be removed effectively.
