Abstract

<P>PROBLEM TO BE SOLVED: To provide an epoch-making washing device capable of easily, inexpensively, and well washing, for example, bridges. <P>SOLUTION: This washing device comprises a water supply hose 4 having a submerged pump 3 at the front end and a water storage part 5 for storing the water supplied through the water supply hose 4. During the washing, a predetermined amount of water is stored in the water storage part 5 and a high-pressure pump 1 is driven to supply a predetermined amount of water from the water stored part 5 in which a predetermined amount of water is stored beforehand to the high-pressure pump 1 even if the supplied amount of water through the water supply hose 4 is increased or decreased. Therefore, the idle driving of the high-pressure pump 1 is prevented from occurring. A filter part 6 for removing impurities from the water is installed in the water supply passage from the water supply hose 4 to the portion where water is supplied to the high-pressure pump 1 through the water storage part 5. The water supply hose 4 is set longer so as to be suspended from the upper part of the bridge toward a river under the bridge and the submerged pump 3 at the end and submerged in the river. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は、例えば橋梁構造物を対象に、堆積土砂や飛来塩分などによる局部劣化の防止を目的とし、例えば河川水を利用して水洗浄を実施する洗浄装置に関するものである。   The present invention relates to, for example, a cleaning apparatus that performs water cleaning using river water, for example, for bridge structures, for the purpose of preventing local deterioration due to sedimentary sediment and flying salt.
一般に、橋梁構造物(以下、単に「橋梁」と呼ぶ)の多くは鋼部材で構成されている為、飛散塩分による鋼部材の腐食など局部劣化を防止する対策が重要であり、よってこの劣化箇所の点検など定期的なメンテナンス作業が実施されている。   In general, since many bridge structures (hereinafter simply referred to as “bridges”) are made of steel members, it is important to take measures to prevent local deterioration such as corrosion of steel members due to scattered salt. Regular maintenance work such as inspections is being carried out.
ところが、一般橋梁の多くで見られる支承周りの堆積土砂が、この劣化箇所の点検などのメンテナンス作業を難しくし、局部劣化を促進する一因となっている。また、支承周りに限らず、伸縮部や排水施設など様々な箇所でも堆積土砂が見られ、いずれも橋梁損傷の誘発原因となっている。   However, the sediment around the bearings found in many general bridges makes maintenance work such as inspection of the deteriorated part difficult and promotes local deterioration. In addition, not only around the bearing but also various places such as expansion and contraction and drainage facilities, sediments are seen, all of which cause bridge damage.
そして、これらの堆積土砂の殆どは、通常時そのまま放置されることが多く、局部劣化の点検などのメンテナンス作業の際に人力によって除去しているのが現状である。   Most of these sediments are usually left as they are, and are currently removed manually during maintenance work such as checking for local deterioration.
そこで、この堆積土砂の除去作業として橋梁の水洗浄が実施されている。しかし、この洗浄方法としては、高圧水を噴射する洗浄装置を使用する方法や、排水管清掃車,側溝清掃車を併用する方法など多々あるものの、いずれも大量の水を要し、その水の供給に多大な手間とコストとを要した。   Therefore, the bridge is washed with water as a work to remove the sediment. However, there are many cleaning methods such as a method using a cleaning device that injects high-pressure water, a method using a drain pipe cleaning car, and a side groove cleaning car in combination. It took a lot of labor and cost to supply.
即ち、例えばこの種の洗浄装置は、大型トラックに洗浄装置と給水タンクとを積載し、この給水タンクから水を給水して洗浄を行うものである(例えば、特許文献1など)。   That is, for example, this type of cleaning apparatus is equipped with a cleaning apparatus and a water supply tank mounted on a large truck, and cleaning is performed by supplying water from the water supply tank (for example, Patent Document 1).
従って、このような大型車両を使用する場合、例えば片側走行などの交通規制を行う必要があり、また事前に交通規制申請の手続きも必要となるなど、非常に煩わしい。   Therefore, when such a large vehicle is used, it is necessary to perform traffic regulation such as one-side traveling, and it is also very troublesome that a procedure for traffic regulation application is required in advance.
更に、例えば積載容量2t以上の大型トラックを用い、仮に2000Lの大容量の給水タンクを積載したとしても、吐出量15L/minの洗浄装置で洗浄作業を行った場合の連続運転時間はわずか2.2時間程度に過ぎず、長時間の作業を行う場合には約2時間おきに給水タンクへの再給水が余儀無くされる。   Further, for example, even if a large truck having a loading capacity of 2 t or more is used and a large capacity water tank of 2000 L is loaded, the continuous operation time when the cleaning operation is performed with a cleaning device having a discharge amount of 15 L / min is only 2. When the work is performed for a long time only for about 2 hours, re-watering to the water supply tank is forced every 2 hours.
同様に、前述の排水管清掃車,側溝清掃車とを併用する方法も、やはり大型トラックに給水タンクを積載して使用するので交通規制を行う必要があり、また給水タンクが空になる度に再度の水供給が必要となるなど、多大な手間とコストとを要した。   Similarly, the method of using the drainage pipe cleaning car and the gutter cleaning car as described above also requires the use of a water supply tank mounted on a large truck, so it is necessary to regulate traffic, and each time the water supply tank becomes empty. It required a lot of labor and cost, such as the need to supply water again.
特開平08−257522号公報JP 08-257522 A
本発明は、上述のような問題点に鑑み、例えば橋梁を洗浄する際に、従来のように大型車両に積載した給水タンクなどから水を給水するのではなくこの橋梁の下方の河川から水を自給して洗浄を行うことができ、よって大量の水を容易に確保できる上に、給水タンクを積載する大型車両も一切不要なので、交通整備を行わずに洗浄作業を行うこともでき、これまでになく簡便に且つ低コストで良好に例えば橋梁などを洗浄できる画期的な洗浄装置を提供することを課題とする。   In view of the above-described problems, the present invention, for example, when cleaning a bridge, does not supply water from a water supply tank or the like loaded on a large vehicle as in the prior art, but from the river below the bridge. Cleaning can be done by self-sufficiency, so a large amount of water can be easily secured, and a large vehicle with a water tank is not required at all, so cleaning work can be done without traffic maintenance. It is an object of the present invention to provide an epoch-making cleaning apparatus that can clean, for example, a bridge and the like easily and inexpensively.

When the high-pressure pump 1 is driven, the tip injection of the cleaning hose 2 is provided. The downstream side of the high-pressure pump 1 is switched from the overflow water channel 13 to the cleaning hose 2 according to the injection start operation of the portion 2A, and the high-pressure pump 1 according to the injection stop operation of the tip injection portion 2A of the cleaning hose 2 The automatic switching valve portion 1A for switching the connection of the downstream side of the pump 1 from the cleaning hose 2 to the overflow water channel 13 is provided in the high-pressure pump 1 according to any one of claims 1 and 2.

また、前記ポンプ駆動操作制御部7は、前記駆動操作部7Aにより前記水中ポンプ3を駆動した際、前記貯水部5に所定の貯水限界量の水が貯水されたことを検知して前記水中ポンプ3の駆動を自動一時停止すると共に、水中ポンプ3の駆動を一時停止することにより前記貯水部5の水が所定の貯水量まで減少したことを検知してこの水中ポンプ3の駆動を自動再開する間歇駆動制御系を備えた構成としたことを特徴とする請求項2,3のいずれか1項に記載の洗浄装置に係るものである。   The pump drive operation control unit 7 detects that a predetermined amount of stored water has been stored in the water storage unit 5 when the submersible pump 3 is driven by the drive operation unit 7A. 3 is automatically paused and the submersible pump 3 is temporarily stopped to detect that the water in the water storage section 5 has been reduced to a predetermined amount of water, and the submersible pump 3 is automatically resumed.

The hose winding parts (11, 12) each capable of being wound and stored, and a gripping operation part (9A) for driving by pushing or pulling the travel base part (9) are provided. It concerns on the washing | cleaning apparatus of any one of -5.
本発明は上述のように、河川などから洗浄に必要な水を調達(給水)できるように構成したから、大量の水をわざわざ大容量の給水タンクに貯水して大型車両で作業現場まで搬送するといった手間が一切不要で、例えば橋梁を洗浄する場合にはその下方に流れる河川の水を洗浄水として使用し、大量の水を非常に簡単に、それだけ低コストに調達することが可能である。   As described above, the present invention is configured so that water necessary for washing can be procured (water supply) from a river or the like, so a large amount of water is purposely stored in a large-capacity water tank and transported to a work site by a large vehicle. For example, when cleaning a bridge, it is possible to procure a large amount of water very easily and at a low cost by using the water of the river flowing below as the cleaning water.
また、精水ではなく河川などの自然の水を利用する場合、どうしても砂,砂利などの不純物が混じる懸念があるが、フィルタ部よってこの不純物を除去した上で高圧ポンプへと給水しているので、この不純物によって高圧ポンプにトラブルが生ずる心配も無い。   In addition, when natural water such as rivers is used instead of sewage, there is a concern that impurities such as sand and gravel will be mixed, but since the impurities are removed by the filter section, water is supplied to the high-pressure pump. There is no concern that this impurity will cause trouble in the high-pressure pump.
更に、本発明では給水ホースを橋梁上からその下方の河川まで到達できるような長尺に設定している為、何らかの影響で給水ホースからの給水量が減少や一時停止した後、給水量が通常状態に復帰した場合に、その給水ホースの先端から給水した水が高圧ポンプまで到達するまでに時間を要し、その間に高圧ポンプの空周りが生ずると故障やトラブルの原因となるが、この点本発明は、何らかの影響により前記給水ホースからの給水量が増減しても貯水部が高圧ポンプへの一定量の給水を維持し、これにより安定した運転が可能で、良好に洗浄作業を実施できる。   Furthermore, in the present invention, since the water supply hose is set to be long enough to reach the river below it from the bridge, the water supply amount is usually reduced after the water supply amount from the water supply hose is reduced or temporarily stopped due to some influence. When it returns to the normal state, it takes time for the water supplied from the tip of the water supply hose to reach the high-pressure pump. In the present invention, even if the amount of water supplied from the water supply hose increases or decreases due to some influence, the water storage unit maintains a certain amount of water supplied to the high-pressure pump, thereby enabling stable operation and good cleaning work. .
例えば上述のように従来の洗浄車や排水管清掃者など大型車両を使用して橋梁の洗浄を行う場合、交通規制が必要でそれだけ手間とコストとを要したが、この点、本発明の洗浄装置は、大容量の給水タンク(例えば2000L容量のタンクなど)を設ける必要が無いのでそれだけコンパクトに設計でき、設計によっては軽トラックの荷台に積載できるようなコンパクトサイズとすることも容易に実現可能である。   For example, as described above, when a bridge is washed using a large vehicle such as a conventional washing car or a drain pipe cleaner, traffic regulation is necessary and much labor and cost are required. Since there is no need to install a large-capacity water tank (for example, a 2000-liter tank), the device can be designed so compactly, and depending on the design, it can easily be made compact so that it can be loaded onto a light truck bed. It is.
以上のように、本発明は、大型車両を使用せず、つまり交通規制を行うことなく洗浄作業を実施でき、作業現場周辺の交通アクセス性を損ねることなく良好に洗浄作業を実施できる上に、交通規制に要する労力や人件費を削減でき大幅なコストダウンを図り得る。   As described above, the present invention can perform a cleaning operation without using a large vehicle, that is, without performing traffic regulation, and can perform a cleaning operation well without impairing traffic accessibility around the work site. The labor and labor costs required for traffic regulation can be reduced and the cost can be greatly reduced.
それでいて洗浄に必要な大量の水は例えば河川などから簡単且つ良好に調達でき、大容量の給水タンクを現場へ搬送する搬送コストもかからず、この点一層作業性及びコスト性に秀れる。   Nevertheless, a large amount of water required for cleaning can be easily and satisfactorily procured from, for example, a river, and there is no transportation cost for transporting a large-capacity water tank to the site.
このように例えば橋梁を簡便に洗浄できる本発明を用いれば、それだけ橋梁の劣化箇所の点検の妨げとなっていた堆積土砂の除去作業を簡単且つ良好に実施でき、この橋梁の点検作業を精度良く実施できる。つまり橋梁の維持管理水準の向上や、ひいてはこの種橋梁のライフサイクルコストの低減効果も見込めるなど、極めて作業性及び実用性に秀れた画期的な洗浄装置となる。   Thus, for example, by using the present invention that can easily clean a bridge, it is possible to easily and satisfactorily carry out the removal work of accumulated sediment that has hindered the inspection of the deteriorated portion of the bridge. Can be implemented. In other words, it is an epoch-making cleaning device that is extremely excellent in workability and practicality. For example, it can be expected to improve the maintenance level of the bridge and to reduce the life cycle cost of this type of bridge.
好適と考える本発明の実施形態(発明をどのように実施するか)を、図面に基づいて本発明の作用を示して簡単に説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.
高圧ポンプ1により水を圧送し、洗浄ホース2の先端噴射部2Aからこの水を噴射して洗浄を行う。この際、先端部に水中ポンプ3を設けた給水ホース4により前記高圧ポンプ1に給水する。   Water is pumped by the high-pressure pump 1, and the water is sprayed from the tip spray section 2 </ b> A of the cleaning hose 2 to perform cleaning. At this time, water is supplied to the high-pressure pump 1 by a water supply hose 4 provided with a submersible pump 3 at the tip.
この給水ホース4から給水した水は、前記高圧ポンプ1に直接給水するのではなく、一旦貯水部5に貯水する。そして、洗浄時には、この貯水部5に所定量の水が貯水された上で前記高圧ポンプ1を駆動する。   The water supplied from the water supply hose 4 is not directly supplied to the high-pressure pump 1 but is temporarily stored in the water storage unit 5. At the time of cleaning, the high-pressure pump 1 is driven after a predetermined amount of water is stored in the water storage section 5.
これにより、給水ホース4による給水量が増減しても、予め所定量の水が貯水された前記貯水部5から前記高圧ポンプ1に一定量の水が給水されてこの高圧ポンプ1の空回り駆動が阻止されることとなる。   As a result, even if the amount of water supplied by the water supply hose 4 increases or decreases, a predetermined amount of water is supplied from the water storage unit 5 in which a predetermined amount of water has been stored in advance to the high pressure pump 1, and the high speed pump 1 is driven idly. Will be blocked.
即ち、給水ホース4による給水量が減少や、場合によっては一時的に停止したとしても、その間貯水部5に貯水された水によって減少分の給水量を補填でき、よって給水ホース4による給水量の増減に関わりなく高圧ポンプ1に一定量の水を給水せしめ、この高圧ポンプ1の安定した運転が可能となる。   That is, even if the amount of water supplied by the water supply hose 4 is reduced or temporarily stopped in some cases, the amount of water supplied by the water storage unit 5 can be compensated by the water stored in the water storage unit 5 during that time. Regardless of the increase or decrease, the high-pressure pump 1 is supplied with a certain amount of water, and the high-pressure pump 1 can be operated stably.
また、本発明では、給水ホース4から貯水部5を介して前記高圧ポンプ1に水を給水するまでの給水路途中にフィルタ部6を備えている。従って、給水ホース4により給水した水に不純物(例えば砂,砂利など)が混じっていても、前記高圧ポンプ1に供給される前に前記フィルタ部6により不純物を除去でき、高圧ポンプ1の故障などのトラブルが阻止されることとなる。   Moreover, in this invention, the filter part 6 is provided in the middle of the water supply path until it supplies water to the said high pressure pump 1 through the water storage part 5 from the water supply hose 4. FIG. Therefore, even if impurities (for example, sand, gravel, etc.) are mixed in the water supplied by the water supply hose 4, the impurities can be removed by the filter unit 6 before being supplied to the high-pressure pump 1, and the high-pressure pump 1 fails. Will be prevented.
更に本発明では、給水ホース4を、橋梁上から下方の河川に向けて垂らして先端部の水中ポンプ3を前記河川に水没させ得る長尺に設定している。   Furthermore, in the present invention, the water supply hose 4 is set to a length that allows the water pump hose 4 to hang down from the bridge toward the river below and the submersible pump 3 at the tip can be submerged in the river.
従って、例えば橋梁の支承周りなどに堆積した土砂を水で洗浄除去する作業を行う際に本発明を使用すれば、長尺な給水ホース4により橋梁の下方の河川から水を給水でき、しかも例えば河川から給水した水に混じった砂,砂利などの不純物によって高圧ポンプ1が故障したり、また例えば何らかの影響で給水量が減り高圧ポンプ1が空回り駆動するといったトラブルも回避でき、河川から水を好きなだけ給水して良好に洗浄作業を実施することができる。その上、従来のように大量の水をわざわざ大容量の給水タンクに貯水して大型車両で作業現場まで搬送するといった手間が一切不要で、当然洗浄作業の間このような給水タンクを積載した大型車両を現場に常駐させる必要も無く、また装置自体も大容量の給水タンクなどスペースの嵩張るものが不要で例えば図示した後述の実施例のように軽トラックの荷台に積載できるようなコンパクトサイズに設計し、軽トラックで現場まで搬送できるなど、これまで必須だった大型車両や現場周辺の交通規制も一切不要とすることが可能で、これまでになく作業性良く簡便に且つ低コストで良好に例えば橋梁などの洗浄を実施できる画期的な洗浄装置となる。   Accordingly, for example, when the present invention is used when washing and removing sediment accumulated around the bridge support with water, the long water supply hose 4 can supply water from the river below the bridge, You can avoid troubles such as sand, gravel, and other impurities mixed in the water supplied from the river, or the trouble that the high-pressure pump 1 is driven idle due to some influence, for example, the water supply is reduced. It is possible to carry out the cleaning operation satisfactorily by supplying as much water as possible. In addition, there is no need to manually store a large amount of water in a large capacity water supply tank and transport it to the work site with a large vehicle. There is no need for the vehicle to be resident on site, and the device itself is not required to have a large space such as a large-capacity water supply tank. For example, it is designed in a compact size that can be loaded on the platform of a light truck as shown in the examples shown later. It is possible to eliminate the need for large vehicles and traffic regulations around the site, such as being able to transport to the site with a light truck. It will be an epoch-making cleaning device that can clean bridges and the like.
また、例えば後述の実施例のように、前記水中ポンプ3を駆動させる駆動操作部7Aを有し、この駆動操作部7Aの駆動操作により前記水中ポンプ3を駆動した際、前記貯水部5に所定量の水が貯水されたことを検知して駆動停止状態の前記高圧ポンプ1を自動駆動する,若しくは駆動停止状態の前記高圧ポンプ1を噴射開始操作に応じて前記洗浄ホース2に水を圧送水可能な待機状態に切り替えせしめるポンプ駆動操作制御部7を備えた構成とした場合には、貯水部5の貯水量を見計らって高圧ポンプ1を停止状態から手動で駆動状態や駆動可能な待機状態へと切り替える作業が不要で、貯水部5に所定量の水が貯水されるとポンプ駆動操作制御部7によって高圧ポンプ1が停止状態から駆動状態や駆動可能な待機状態に自動で切り替えられる為、洗浄時には前記駆動操作部7Aによる水中ポンプ3の駆動操作(始動操作)だけで水中ポンプ3と高圧ポンプ1の双方を駆動操作でき、一層作業性に秀れることとなる。   Further, for example, as in an embodiment to be described later, a drive operation unit 7A for driving the submersible pump 3 is provided, and when the submersible pump 3 is driven by a drive operation of the drive operation unit 7A, It detects that a certain amount of water has been stored and automatically drives the high-pressure pump 1 in a stopped state, or pumps water into the cleaning hose 2 in response to an operation to start the high-pressure pump 1 in a stopped state. When the pump drive operation control unit 7 is switched to a possible standby state, the amount of water stored in the water storage unit 5 is estimated and the high-pressure pump 1 is manually switched from a stopped state to a drive state or a driveable standby state. When a predetermined amount of water is stored in the water storage unit 5, the pump drive operation control unit 7 automatically switches the high-pressure pump 1 from a stopped state to a driving state or a drivable standby state. That reason, at the time of cleaning can be driven operation (start operation) only driving operation both the water pump 3 and the high-pressure pump 1 in water pump 3 by the drive operation portion 7A, and thus are Xiu even more workability.
また更にこのポンプ駆動操作制御部7は、例えば前記駆動操作部7Aにより前記水中ポンプ3を駆動した際、前記貯水部5に所定の貯水限界量の水が貯水されたことを検知して前記水中ポンプ3の駆動を自動一時停止すると共に、水中ポンプ3の駆動を一時停止することにより前記貯水部5の水が所定の貯水量まで減少したことを検知してこの水中ポンプ3の駆動を自動再開する間歇駆動制御系を備えた構成とした場合には、水中ポンプ3の無駄な駆動を低減でき、それだけエネルギー効率の向上を図り得、この点一層実用性に秀れることとなる。即ち、例えば洗浄作業の最中に、洗浄ホース2の先端噴射部2Aからの噴射を一時停止させても依然として給水ホース4の水中ポンプ3が駆動している場合、その間に給水された余水が例えば後述の実施例のように貯水部5のオーバーフロー水路14や、例えば前記高圧ポンプ1のオーバーフロー水路13から排水され、その間に水中ポンプ3を駆動する為に要したエネルギーは無駄に帰すこととなるが、これに対して上述のように間歇駆動制御系を備えた構成とした場合には、例えば水の噴射を一時停止して貯水部5に所定の貯水限界量の水が貯水されると、ポンプ駆動操作制御部7の間歇駆動制御系によって水中ポンプ3の駆動が自動で一時停止され、その後、例えば水の噴射を再開して貯水部5の水がある程度の量まで減少すると水中ポンプ3の駆動が自動再開され、それだけエネルギーの無駄を低減でき、環境に良い上にエネルギーコストの削減により洗浄作業コストの低減を一層図り得ることとなる。   Further, the pump drive operation control unit 7 detects that a predetermined amount of water has been stored in the water storage unit 5 when the submersible pump 3 is driven by the drive operation unit 7A, for example, to detect the underwater pump. The driving of the pump 3 is automatically paused, and the driving of the submersible pump 3 is automatically stopped by detecting that the water in the reservoir 5 has been reduced to a predetermined amount by temporarily stopping the driving of the submersible pump 3. In the case where the intermittent drive control system is provided, useless driving of the submersible pump 3 can be reduced, and energy efficiency can be improved accordingly, and this point is further practical. That is, for example, if the submersible pump 3 of the water supply hose 4 is still driven even if the injection from the tip injection part 2A of the cleaning hose 2 is temporarily stopped during the cleaning operation, the remaining water supplied during that time For example, as in the embodiment described later, the energy required for driving the submersible pump 3 during the drainage from the overflow channel 14 of the reservoir 5 or the overflow channel 13 of the high-pressure pump 1, for example, is wasted. However, in the case where the intermittent drive control system is provided as described above, for example, when water injection is temporarily stopped and water of a predetermined storage limit amount is stored in the water storage unit 5, When the drive of the submersible pump 3 is automatically suspended by the intermittent drive control system of the pump drive operation control unit 7, and then the water injection in the water storage unit 5 is reduced to a certain amount by restarting the water injection, for example. The driving of No. 3 is automatically resumed, so that waste of energy can be reduced accordingly, and it is good for the environment, and further, it is possible to further reduce the cleaning work cost by reducing the energy cost.
尚、本発明に係る洗浄装置は橋梁の洗浄に限らず、例えばビルなどの建築構造物の洗浄や、例えば自動車の洗浄など種々の用途に使用可能である。   The cleaning device according to the present invention is not limited to the cleaning of bridges, but can be used for various purposes such as cleaning of building structures such as buildings and cleaning of automobiles.
本発明の具体的な実施例について図面に基づいて説明する。   Specific embodiments of the present invention will be described with reference to the drawings.
本実施例は、高圧ポンプ1により水を圧送し、洗浄ホース2の先端噴射部2Aから前記水を噴射する洗浄装置であって、先端部に水中ポンプ3を設けた給水ホース4と、この給水ホース4により給水した水を貯水する貯水部5とを備え、洗浄時には、前記貯水部5に所定量の水が貯水された上で前記高圧ポンプ1を駆動することで、前記給水ホース4による給水量が増減しても予め所定量の水が貯水された前記貯水部5から前記高圧ポンプ1に一定量の水が給水されてこの高圧ポンプ1の空回り駆動が阻止されるように構成し、前記給水ホース4から貯水部5を介して前記高圧ポンプ1に水を給水するまでの給水路途中にフィルタ部6を備え、前記給水ホース4により給水した水が前記フィルタ部6により不純物を除去された上で前記高圧ポンプ1へと給水されるように構成すると共に、前記給水ホース4は、橋梁上から下方の河川に向けて垂らして先端部の水中ポンプ3を前記河川に水没させ得る長尺に設定した洗浄装置である。   The present embodiment is a cleaning device that pumps water from a high-pressure pump 1 and injects the water from the tip injection portion 2A of the cleaning hose 2, and includes a water supply hose 4 provided with a submersible pump 3 at the tip, and the water supply A water storage part 5 for storing water supplied by the hose 4, and at the time of cleaning, a predetermined amount of water is stored in the water storage part 5 and then the high-pressure pump 1 is driven to supply water by the water supply hose 4. Even if the amount increases or decreases, a predetermined amount of water is supplied to the high-pressure pump 1 from the water storage unit 5 in which a predetermined amount of water is stored in advance, and the idling drive of the high-pressure pump 1 is prevented, A filter unit 6 is provided in the middle of the water supply path from the water supply hose 4 to the high pressure pump 1 through the water storage unit 5 until water is supplied, and impurities supplied to the water supplied by the water supply hose 4 are removed by the filter unit 6. Above the high pressure port The water supply hose 4 is configured to have a long length so that the water supply hose 4 hangs down from the bridge toward the river below and the submersible pump 3 at the tip can be submerged in the river. It is.
以下、本実施例の洗浄装置の各構成を具体的に説明する。   Hereafter, each structure of the washing | cleaning apparatus of a present Example is demonstrated concretely.
給水ホース4は、その基端側にして下流側をフィルタ部6を介して貯水部5に接続している。   The water supply hose 4 is connected to the water storage unit 5 through the filter unit 6 on the downstream side with the base end side thereof.
給水ホース4の先端部には電気駆動タイプの水中ポンプ3を設けており、この水中ポンプ3から前記給水ホース4に沿って電源コードが延設され、そのコード基端部が後述の電源部(図示省略)に電気的に接続されている。   An electric drive type submersible pump 3 is provided at the distal end of the water supply hose 4, and a power cord is extended from the submersible pump 3 along the water supply hose 4. (Not shown).
また、この給水ホース4を、本実施例では全長約30mの長尺に設定している。従って、前記水中ポンプ3には、この全長30mの長尺な給水ホース4を通じて水を汲み上げ可能な高揚呈のものを採用する。具体的には、DC電源タイプに比して小型設計で且つ高揚呈の軽便なものが多く市販されているAC電源タイプの水中ポンプ3を採用する。   Moreover, this water supply hose 4 is set to a long length of about 30 m in the present embodiment. Accordingly, the submersible pump 3 employs a pump that can pump water through the long water supply hose 4 having a total length of 30 m. Specifically, an AC power type submersible pump 3 that is commercially available in many small-sized, high-lifting and light-weight types compared to the DC power type is adopted.
電気駆動タイプであるこの水中ポンプ3は、電源のON/OFF切り替えによりポンプ駆動を簡単に素早くのON/OFF切り替え操作できる為、後述のように間歇駆動制御系により駆動をON/OFF自動切り替えを行う本実施例に適している。また、給水ホース4の基端側にポンプを設けるのではなく、給水ホース4の先端部に水中ポンプ3を設けて水を汲み上げる構成は高揚呈に適しており、この点、給水ホース4を非常に長尺に設定する為に高揚呈を必要とする本実施例に適した構成と言える。   This submersible pump 3, which is an electric drive type, can be quickly and easily switched on and off by switching the power ON / OFF, so the intermittent drive control system can automatically switch the drive on and off as described later. Suitable for this embodiment to be performed. In addition, a pump is not provided on the base end side of the water supply hose 4 but a structure in which the submersible pump 3 is provided at the tip of the water supply hose 4 to pump up water is suitable for uplifting. It can be said that this is a configuration suitable for the present embodiment that requires high elevation in order to set it to a long length.
また、図1に図示したように、この給水ホース4の基端部はフィルタ部6と接続している。このフィルタ部6には既存の川水フィルタを採用しており、更に具体的には、本実施例では100メッシュのサイクロン式フィルタを採用している。そして、このフィルタ部6の下流側を前記貯水部5の上部に接続している。   Further, as shown in FIG. 1, the proximal end portion of the water supply hose 4 is connected to the filter portion 6. The filter unit 6 employs an existing river water filter, and more specifically, a 100 mesh cyclone filter is employed in this embodiment. The downstream side of the filter unit 6 is connected to the upper part of the water storage unit 5.
従って、本実施例は、給水ホース4で例えば河川の川水など自然の水を給水して洗浄水として使用するが、仮にこの給水した水に川砂などの不純物が混じっていてもフィルタ部6により除去し、高圧ポンプ1の高寿命化を図ることができる。   Therefore, in this embodiment, natural water such as river water of the river is supplied by the water supply hose 4 and used as cleaning water. However, even if impurities such as river sand are mixed in the supplied water, the filter unit 6 It can be removed and the life of the high-pressure pump 1 can be extended.
尚、このように本実施例ではフィルタ部6を給水ホース4と貯水部5との間に設けているが、例えば貯水部5と高圧ポンプ1との間の水路など、給水ホース4から高圧ポンプ1に給水するまでの水路途中であればどこに設けても良い。   In this way, in this embodiment, the filter unit 6 is provided between the water supply hose 4 and the water storage unit 5, but the water supply hose 4 to the high pressure pump, such as a water channel between the water storage unit 5 and the high pressure pump 1, for example. It may be provided anywhere as long as it is in the middle of the water channel until water is supplied to 1.
また、貯水部5は、洗浄に必要な大量の水を貯水するのではなく、あくまでも洗浄に必要な水は河川から給水し、その水を一時的に貯水部5に貯水できれば良い。つまり、前記水中ポンプ3が駆動している間に、高圧ポンプ1への給水を補助するだけの貯水量が確保できれば良いので、それほど大きい容量のものは要さず小さい容量のものを採用できる。本実施例においては20L容量の貯水容器を貯水部5として採用している。   In addition, the water storage unit 5 does not store a large amount of water necessary for cleaning, but it is only necessary to supply water necessary for cleaning from the river and temporarily store the water in the water storage unit 5. That is, it is only necessary to secure a water storage amount that assists water supply to the high-pressure pump 1 while the submersible pump 3 is being driven. In the present embodiment, a 20 L capacity water storage container is employed as the water storage section 5.
また、この貯水部5は、所定の貯水限界量を超えて貯水しきれなかった余水をこの貯水部5から外方へ排水するオーバーフロー水路14を設けている。具体的には、図1に図示したように、貯水部5の天井部から排水ホースを延設して貯水部5が貯水限界量を超えるとこのオーバーフロー水路14としての排水ホースから排水する構成としている。   In addition, the water storage unit 5 is provided with an overflow water channel 14 through which excess water that cannot be stored exceeding a predetermined water storage limit amount is discharged from the water storage unit 5 to the outside. Specifically, as illustrated in FIG. 1, a drainage hose is extended from the ceiling of the water storage unit 5 and drained from the drainage hose as the overflow channel 14 when the water storage unit 5 exceeds the storage limit amount. Yes.
また更に、この貯水部5の天井部には後述の高圧ポンプ1のオーバーフロー水路13が接続されており、高圧ポンプ1からの余水はこのオーバーフロー水路13を介して貯水部5に戻されるように構成している。   Furthermore, an overflow water channel 13 of the high pressure pump 1 described later is connected to the ceiling portion of the water storage unit 5, and surplus water from the high pressure pump 1 is returned to the water storage unit 5 through the overflow water channel 13. It is composed.
従って、高圧ポンプ1からの余水は排水しても良いが本実施例では貯水部5に戻して再度利用できるようにしている為、無駄を軽減できより効率的に給水できる。また、仮にこの貯水部5が貯水限界量に達したとしても、余水が自然に排水されるので貯水部5や高圧ポンプ1,水中ポンプ3に負荷がかかることは無い。   Accordingly, the remaining water from the high-pressure pump 1 may be drained, but in this embodiment, it is returned to the water storage unit 5 so that it can be reused, so that waste can be reduced and water can be supplied more efficiently. Further, even if the water storage unit 5 reaches the water storage limit amount, the remaining water is drained naturally, so that no load is applied to the water storage unit 5, the high-pressure pump 1, and the submersible pump 3.
また、この貯水部5には、貯水量(水位)を検知する水位センサー17を設けている。この水位センサー17は、例えば貯水部5の水位を無段階に検知できる構成としても良いし、所定の各水位高さ位置に夫々感知素子を設けてその各水位高さ位置に貯水量が到達しているか否かを検知するように構成しても良い。   The water storage section 5 is provided with a water level sensor 17 for detecting the amount of water stored (water level). For example, the water level sensor 17 may be configured to detect the water level of the water storage unit 5 steplessly, or a sensing element is provided at each predetermined water level height position so that the water storage amount reaches each water level height position. You may comprise so that it may detect whether it is.
また、本実施例では、この水位センサー17の検知結果を基に高圧ポンプ1の駆動を制御するポンプ駆動操作制御部7を備えている。   In this embodiment, a pump drive operation control unit 7 that controls the drive of the high-pressure pump 1 based on the detection result of the water level sensor 17 is provided.
具体的には、前記水中ポンプ3を駆動させる駆動操作部7Aを有し、この駆動操作部7Aの駆動操作により前記水中ポンプ3を駆動した際、前記貯水部5に所定量の水が貯水されたことを検知して駆動停止状態の前記高圧ポンプ1を自動駆動する,若しくは駆動停止状態の前記高圧ポンプ1を噴射開始操作に応じて前記洗浄ホース2に水を圧送水可能な待機状態に自動切り替えするポンプ駆動操作制御部7を備えた構成としている。   Specifically, it has a drive operation unit 7A for driving the submersible pump 3, and when the submersible pump 3 is driven by the drive operation of the drive operation unit 7A, a predetermined amount of water is stored in the water storage unit 5. And automatically driving the high-pressure pump 1 in a stopped state, or automatically setting the high-pressure pump 1 in a stopped state to a standby state in which water can be pumped to the washing hose 2 in response to an injection start operation. It is set as the structure provided with the pump drive operation control part 7 to switch.
即ち、このポンプ駆動操作制御部7の駆動操作部7Aにより水中ポンプ3の駆動を開始操作して給水ホース4からの給水が開始されても、前記貯水部5に前記所定量の水が貯水されるまでは、高圧ポンプ1は停止状態であり、たとえ後述の洗浄ホース2の先端噴射部2A(洗浄ガンユニット)の噴射操作部2a(トリガー部)を噴射開始操作しても高圧ポンプ1は駆動せず水も噴射されない。一方、前記水位センサー17により貯水部5に所定量の水が貯水されたことが検知されると、このポンプ駆動操作制御部7によって前記高圧ポンプ1が停止状態から駆動状態,或いは駆動可能な待機状態(噴射開始操作により駆動を開始して水の噴射を開始できる待機状態)に自動で切り替えられる。   That is, even when the drive operation unit 7A of the pump drive operation control unit 7 starts driving of the submersible pump 3 and water supply from the water supply hose 4 is started, the predetermined amount of water is stored in the water storage unit 5. Until then, the high-pressure pump 1 is in a stopped state, and the high-pressure pump 1 is driven even if the injection operation portion 2a (trigger portion) of the tip injection portion 2A (cleaning gun unit) of the cleaning hose 2 to be described later is started. No water is injected. On the other hand, when it is detected by the water level sensor 17 that a predetermined amount of water has been stored in the water storage unit 5, the pump drive operation control unit 7 drives the high-pressure pump 1 from a stopped state to a standby state or a driveable standby state. It is automatically switched to a state (a standby state in which driving can be started by an injection start operation and water injection can be started).
従って、貯水部5の貯水量を見計らって適当なタイミングで高圧ポンプ1の駆動を手動で開始させる必要が無く、水中ポンプ3の駆動を駆動操作部7Aにより手動で開始操作すれば、後は貯水部5に所定量の水が貯水した適宜なタイミングで自動的に高圧ポンプ1が駆動状態,或いは駆動可能な待機状態に切り替わり、操作性に秀れる。   Accordingly, there is no need to manually start the high-pressure pump 1 at an appropriate timing by measuring the amount of water stored in the water storage unit 5, and if the drive operation of the submersible pump 3 is manually started by the drive operation unit 7A, The high-pressure pump 1 is automatically switched to a driving state or a drivable standby state at an appropriate timing when a predetermined amount of water is stored in the unit 5, and the operability is excellent.
また例えば、貯水部5の貯水量が所定の少量限界量に達したことを前記水位センサー17で検知して、高圧ポンプ1の駆動を自動で停止状態に切り替える制御部を備えれば、高圧ポンプ1の駆動の開始だけでなく停止も適宜なタイミングで自動的に実施でき、操作性に秀れると共に高圧ポンプ1の空回り駆動を確実に防げる。   Further, for example, if the water level sensor 17 detects that the amount of water stored in the water storage unit 5 has reached a predetermined small amount limit amount, and includes a control unit that automatically switches the driving of the high pressure pump 1 to a stopped state, the high pressure pump Not only the start of driving 1 but also the stop can be automatically performed at an appropriate timing, so that the operability is excellent and the idling drive of the high-pressure pump 1 can be reliably prevented.
尚、貯水部5に所定量の水が貯水されたことを前記水位センサー17で検知した際、前記ポンプ駆動操作制御部7により前記高圧ポンプ1が自動駆動して前記洗浄ホース2への圧送水が自動的に開始し噴射が開始されるように構成しても良いが、本実施例においては、ポンプ駆動操作制御部7により高圧ポンプ1が前記圧送水可能な待機状態に自動切り替えされるように構成している。具体的な説明は後述するが、洗浄ホース2の先端噴射部2A(洗浄ガンユニット)の噴射操作部2a(トリガー部)を噴射開始操作すると、後述の自動切り替え弁1Aにより高圧ポンプ1の下流側が洗浄ホース2へと接続切り替えされると共に、この高圧ポンプ1が圧送水を開始して洗浄ホース2の先端噴射部2Aから水が噴射され、またこの噴射操作部2a(トリガー部)を噴射停止操作すると、高圧ポンプ1の圧送水が停止されると共に圧送ポンプ1の下流側が洗浄ホース2からオーバーフロー水路13へと接続切り替えされるように構成している。   When the water level sensor 17 detects that a predetermined amount of water has been stored in the water storage unit 5, the high-pressure pump 1 is automatically driven by the pump drive operation control unit 7 to supply pressure to the cleaning hose 2. However, in this embodiment, the high pressure pump 1 is automatically switched to the standby state in which the pressure water can be supplied by the pump drive operation control unit 7. It is configured. Although specific description will be given later, when the injection operation unit 2a (trigger unit) of the tip injection unit 2A (cleaning gun unit) of the cleaning hose 2 is operated to start injection, the automatic switching valve 1A described later causes the downstream side of the high-pressure pump 1 to The connection to the cleaning hose 2 is switched, the high-pressure pump 1 starts pumping water, water is injected from the tip injection part 2A of the cleaning hose 2, and the injection operation part 2a (trigger part) is operated to stop injection. Then, the pressure water supply of the high-pressure pump 1 is stopped and the downstream side of the pressure pump 1 is switched from the washing hose 2 to the overflow water channel 13.
また、このポンプ駆動操作制御部7は、前記駆動操作部7Aにより前記水中ポンプ3を駆動した際、前記貯水部5に所定の貯水限界量の水が貯水されたことを検知して前記水中ポンプ3の駆動を自動一時停止すると共に、水中ポンプ3の駆動を一時停止することにより前記貯水部5の水が所定の貯水量まで減少したことを検知してこの水中ポンプ3の駆動を自動再開する間歇駆動制御系を備えている。   The pump drive operation control unit 7 detects that a predetermined amount of water has been stored in the water storage unit 5 when the submersible pump 3 is driven by the drive operation unit 7A, and detects the submersible pump. 3 is automatically paused and the submersible pump 3 is temporarily stopped to detect that the water in the water storage section 5 has been reduced to a predetermined amount of water, and the submersible pump 3 is automatically resumed. It has an intermittent drive control system.
即ち、例えば水の噴射を停止操作するなどして貯水部5に所定の貯水限界量の水が貯水された際、依然として水中ポンプ3が駆動し続けると、貯水部5のオーバーフロー水路14から余水が排水されることとなり、その間の水中ポンプ3の駆動に要したエネルギーが無駄に帰すこととなるが、この点、本実施例では貯水部5が貯水限界に達すると自動的に水中ポンプ3が駆動停止し、その後貯水部5の水が所定量まで減少すると自動的に水中ポンプ3が駆動再開する為、水中ポンプ3を無駄に駆動させずそれだけエネルギー効率に秀れる。   That is, for example, when a predetermined storage limit amount of water is stored in the water storage unit 5 by stopping the water injection, if the submersible pump 3 continues to be driven, the remaining water from the overflow channel 14 of the water storage unit 5 However, in this embodiment, when the water storage unit 5 reaches the water storage limit, the submersible pump 3 is automatically turned off. When the drive is stopped and then the water in the water storage section 5 decreases to a predetermined amount, the submersible pump 3 automatically resumes driving, so that the submersible pump 3 is not driven wastefully and the energy efficiency is improved accordingly.
また、本実施例では、このポンプ駆動操作制御部7の駆動操作部7Aとして、図3に図示したように後述の走行台部9の筐体部9Bの上面部に操作パネルを設けている。この操作パネル(駆動操作部7A)は、前記水中ポンプ3の駆動の始動及び停止を操作可能なボタンを有し、また給水異常や後述のエンジンユニットのバッテリ18の電圧低下など装置の異常を示す表示部(警告ランプ)を備えた構成とする。また、図示はしていないが、このポンプ駆動操作制御部7は、操作パネルによる操作信号や、前記水位センサー17の検知信号などを受けて前記水中ポンプ3,高圧ポンプ1及び後述のエンジンユニットのエンジン19の各々の駆動を制御する制御盤を備えている。   Further, in this embodiment, as the drive operation unit 7A of the pump drive operation control unit 7, an operation panel is provided on the upper surface portion of a casing unit 9B of the traveling table unit 9 described later as shown in FIG. This operation panel (drive operation unit 7A) has buttons that can be used to start and stop the driving of the submersible pump 3, and indicates an abnormality in the apparatus such as a water supply abnormality or a voltage drop in the battery 18 of the engine unit described later. The display unit (warning lamp) is provided. Although not shown, the pump drive operation control unit 7 receives an operation signal from the operation panel, a detection signal from the water level sensor 17, and the like. A control panel for controlling each drive of the engine 19 is provided.
高圧ポンプ1には、エンジン19を原動力に駆動するエンジンポンプを採用している。   The high-pressure pump 1 employs an engine pump that drives the engine 19 as a driving force.
本実施例ではこの高圧ポンプ1を駆動する為のエンジンユニットを設けており、図1に図示したように、このエンジンユニットのガソリン駆動式のエンジン19の原動力をプーリを介して高圧ポンプ1に機械的エネルギーとして伝達して、この高圧ポンプ1をエンジン駆動させている。   In this embodiment, an engine unit for driving the high-pressure pump 1 is provided. As shown in FIG. 1, the motive power of the gasoline-driven engine 19 of the engine unit is transferred to the high-pressure pump 1 via a pulley. This high-pressure pump 1 is driven by the engine.
また、このエンジンユニットには発電部20(ダイナモやオルタネータなど。本実施例ではオルタネータを採用)が備えられ、図1に図示したように前記エンジン19とこの発電部20(オルタネータ)とをプーリで接続し、エンジン19を駆動源として発電部20で発電を行うようにしている。更にこのエンジンユニットで発電した電力を蓄電するバッテリ18(DCバッテリ)と、このバッテリ18に蓄電された電力をDC/AC変換するDC/ACインバータ21とを備え、このインバータ21をAC電源として前記水中ポンプ3の電源コードの基端部を接続し、この水中ポンプ3を電気駆動せしめる構成とする。   Further, the engine unit is provided with a power generation unit 20 (such as a dynamo and an alternator. In this embodiment, an alternator is used). As shown in FIG. 1, the engine 19 and the power generation unit 20 (alternator) are connected by a pulley. The power generation unit 20 generates power using the engine 19 as a drive source. Furthermore, a battery 18 (DC battery) for storing electric power generated by the engine unit and a DC / AC inverter 21 for DC / AC converting the electric power stored in the battery 18 are provided, and the inverter 21 is used as an AC power source. The base end of the power cord of the submersible pump 3 is connected, and the submersible pump 3 is electrically driven.
また前記エンジンユニットで発電してバッテリ18に蓄電した電力は、単にインバータ21を介して前記水中ポンプ3の駆動電力として使用するだけでなく、前記エンジン19を始動する際のスタータモータの駆動電力としても併用している他、前記ポンプ駆動操作制御部7の制御盤や操作パネルの表示部(警告ランプ)への電力供給にも併用している。   The electric power generated by the engine unit and stored in the battery 18 is not only used as driving power for the submersible pump 3 via the inverter 21 but also as driving power for the starter motor when starting the engine 19. Is also used for power supply to the control panel of the pump drive operation control unit 7 and the display unit (warning lamp) of the operation panel.
尚、図4は本実施例に係る洗浄装置のシステム系統図を示すものである。この図4に図示したように、貯水部5に所定量の水が貯水されたことを水位センサー17により検知した場合、その検知結果を基にポンプ駆動操作制御部7の制御盤からエンジンユニットを始動させる制御信号が発せられ、スタータモータがバッテリの電力を利用してエンジンを始動せしめ、これにより高圧ポンプ1が駆動状態,或いは圧送水可能な待機状態に切り替わる。更にエンジンを原動力に発電部20(オルタネータ)にて発電された電力がバッテリ18に蓄電される。このバッテリ18の電力をインバータ21によりDC/AC変換し、このインバータ21をAC電源とし、前記給水ポンプ3が電気駆動する。一方、貯水部5に所定の貯水限界量まで水が貯水されたことを水位センサー17により検知した場合、その検知結果を基に制御盤からインバータ21にAC電源供給停止信号が発せられ、水中ポンプ3の電気駆動が一時的に停止され、その後貯水部5の貯水量が所定量まで減少したことを前記水位センサー17により検知した場合、その検知結果を基に制御盤からインバータ21にAC電源供給再開信号が発せられ、水中ポンプ3が自動的に電気駆動を再開する。   FIG. 4 is a system diagram of the cleaning apparatus according to this embodiment. As shown in FIG. 4, when the water level sensor 17 detects that a predetermined amount of water has been stored in the water storage unit 5, the engine unit is removed from the control panel of the pump drive operation control unit 7 based on the detection result. A start control signal is issued, and the starter motor uses the power of the battery to start the engine, whereby the high-pressure pump 1 is switched to a driving state or a standby state in which pressure water can be supplied. Furthermore, the electric power generated by the power generation unit 20 (alternator) using the engine as a driving force is stored in the battery 18. The electric power of the battery 18 is DC / AC converted by the inverter 21, and the water supply pump 3 is electrically driven by using the inverter 21 as an AC power source. On the other hand, when the water level sensor 17 detects that water has been stored in the water storage section 5 up to a predetermined storage limit, an AC power supply stop signal is issued from the control panel to the inverter 21 based on the detection result, and the submersible pump When the water level sensor 17 detects that the electric drive of No. 3 has been temporarily stopped and then the water storage amount of the water storage section 5 has decreased to a predetermined amount, AC power is supplied from the control panel to the inverter 21 based on the detection result. A restart signal is issued, and the submersible pump 3 automatically restarts electric drive.
