Description

本発明は、積雪寒冷地において、路面が滑り易い雪氷状態になるのを防止する為、路面に対して液状凍結防止剤を供給する液状凍結防止剤供給装置に関するものである。   The present invention relates to a liquid antifreezing agent supply device for supplying a liquid antifreezing agent to a road surface in order to prevent the road surface from becoming slippery snow and ice in a snowy cold region.

上記した液状凍結防止剤供給装置として、多孔質道路に小孔を多数有するパイプを埋め、このパイプに液状凍結防止剤をポンプで圧送して路面へ液状凍結防止剤を滲み出させることにより、路面が滑り易い雪氷状態になるのを防止するものが提案されている（特許文献１）。   As the above-mentioned liquid antifreezing agent supply device, a pipe having a large number of small holes is buried in a porous road, and the liquid antifreezing agent is oozed out to the road surface by pumping the liquid antifreezing agent into the pipe by a pump. Has been proposed that prevents the snow from becoming slippery snow and ice (Patent Document 1).

また、複数の吹き出し口を有するノズルを露出させて道路に埋めたり、または、複数の吹き出し口を有するノズルを道路に沿って設置し、このノズルにパイプを介して液状凍結防止剤を、ポンプで圧送して路面へ散布する手段を各センサーの出力に基づいて制御盤ユニットで制御することにより、路面が滑り易い雪氷状態になるのを防止する液状凍結防止剤供給装置が提案されている（特許文献２）。   Also, a nozzle having a plurality of outlets is exposed and buried in the road, or a nozzle having a plurality of outlets is installed along the road, and a liquid antifreeze agent is pumped to the nozzles through a pipe. There has been proposed a liquid antifreeze supply device that prevents the road surface from becoming slippery snow and ice by controlling the means for pumping and spraying on the road surface with a control panel unit based on the output of each sensor (patent) Reference 2).

さらに、各センサーの出力に基づいて演算制御装置でポンプを制御することにより、パイプを介して液状凍結防止剤をポンプで圧送して路面へ供給することにより、路面が滑り易い雪氷状態になるのを防止する液状凍結防止剤供給装置が提案されている（特許文献３）。   Furthermore, by controlling the pump with the arithmetic and control unit based on the output of each sensor, the liquid antifreezing agent is pumped through the pipe and supplied to the road surface, so that the road surface becomes slippery snow and ice. There has been proposed a liquid antifreeze supply device for preventing the above (Patent Document 3).

また、内部に貯留室が設けられたマットに吹き出しノズルを設けるとともに、貯留タンクから貯留室側へのみ液状凍結防止剤を、パイプを介して供給できる構造とし、道路に埋めたマット上を車両のタイヤが通過することによって吹き出しノズルから液状凍結防止剤を路面へ吹き出させることにより、路面が滑り易い雪氷状態になるのを防止する液状凍結防止剤供給装置が提案されている（特許文献４）。   In addition, a blowing nozzle is provided in a mat provided with a storage chamber inside, and a liquid antifreezing agent can be supplied from the storage tank only to the storage chamber side through a pipe. There has been proposed a liquid anti-freezing agent supply device that prevents the road surface from becoming slippery snow and ice by blowing the liquid anti-freezing agent from the blowing nozzle to the road surface by passing the tire (Patent Document 4).

さらに、開放した上面を露出させて道路に埋めた滲み出し部に、貯留補助タンクとの高低差によって液状凍結防止剤を、パイプを介して供給して路面へ滲み出させることにより、路面が滑り易い雪氷状態になるのを防止する液状凍結防止剤供給装置が提案されている（特許文献５）。   Furthermore, the surface of the road is slipped by supplying liquid antifreeze agent through a pipe to the oozing part exposed on the road with the exposed upper surface exposed and buried in the road, depending on the height difference from the storage auxiliary tank. There has been proposed a liquid antifreezing agent supply device that prevents an easy snow and ice state (Patent Document 5).

また、上面が路面に露出するように埋設された散布ノズルから、圧送された防氷剤を路面に散布する無人運転が可能な路面の凍結防止及び氷雪融解システムが提案されている（特許文献６）。   Further, there has been proposed a road surface freezing prevention and ice / snow melting system capable of unmanned operation in which a sprayed anti-icing agent is sprayed onto a road surface from a spray nozzle embedded so that the upper surface is exposed on the road surface (Patent Document 6). ).

また、ピストン駆動により、凍結防止剤を水鉄砲のように噴出して均一状に路面に散布する凍結防止方法が提案されている（特許文献７）。   Further, there has been proposed an antifreezing method in which an antifreezing agent is ejected like a water gun and sprayed uniformly on a road surface by driving a piston (Patent Document 7).

また、液の供給部を複数台設置して長距離区間の液状凍結防止剤の噴射供給する方法が提案されている（特許文献８）。   Further, a method has been proposed in which a plurality of liquid supply units are installed and sprayed and supplied with a liquid antifreezing agent in a long-distance section (Patent Document 8).

しかしながら、従来の特許文献１、２、３、４、５、６に記載されたように、路面に液状凍結防止剤を供給する為の供給口を、道路に多孔質のパイプ、ノズル、マット及び滲み出し部等を埋設或いは各種検知器を路面内に埋設する方法では、埋設工事費を必要とし、路面の耐久性を低下させ、路面の維持管理に多額の費用を要するばかりでなく、移設及び一時的な撤去も容易に行うことが出来ない。
これを解決する手段として、特許文献７に記載されたように、土木工事を必要とせず、均一状に路面に散布が可能なピストン・シリンダー式の噴射散布方式が提案された。
また、特許文献８に記載されたように長距離区間で散布する方式が提案された。 However, as described in the conventional patent documents 1, 2, 3, 4, 5, and 6, the supply port for supplying the liquid antifreezing agent to the road surface has a porous pipe, nozzle, mat, and In the method of burying the exudation part etc. or embedding various detectors in the road surface, it requires burial work costs, reduces the durability of the road surface, and requires a large amount of expenses for road surface maintenance management. Temporary removal cannot be easily performed.
As a means for solving this problem, as described in Patent Document 7, a piston / cylinder type spray spraying method has been proposed in which civil engineering work is not required and spraying can be performed uniformly on the road surface.
Further, as described in Patent Document 8, a method of spraying in a long distance section has been proposed.

ところが、特許文献７に記載されたような散布装置では、路面に均一に散布するため、車両のタイヤによる凍結防止剤の引きずり及び拡散に不必要な範囲にも散布をすると云う問題が存在した。   However, in the spraying device as described in Patent Document 7, there is a problem that spraying is performed even in a range unnecessary for dragging and diffusion of the antifreezing agent by the vehicle tire in order to spray uniformly on the road surface.

また、特許文献８に記載されたような散布装置では、長距離区間の設置となるため、設置工事に費用がかかると云う問題が存在した。   Moreover, in the spreading device as described in Patent Document 8, since there is a long distance section, there is a problem that the installation work is expensive.

液状凍結防止剤２６を貯留する貯留部１と、各種外部状況を検出するセンサー部５と、前記センサー部５の検出結果に応じて供給時、及び供給量を制御する制御部３と、路側に設置し前記液状凍結防止剤２６を路面に供給する噴射ノズル部４と、前記液状凍結防止剤２６を貯留部１から噴射ノズル部４まで供給する液供給部２と、前記液供給部２、センサー部５、表示部６、通信部７、制御部３を駆動する電源部３０とを備えたものであって、前記液供給部２はポンプ１０等の間欠圧送手段、管路を開閉する噴射電動弁１１を備え、前記噴射ノズル部４は噴射方向を調節できる自在継ぎ手を備え、前記液供給部２と噴射ノズル部４を送液管２１で接続することにより、液供給部２と噴射ノズル部４とを分離配置できる。 Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an embodiment. FIG. 1 is an explanatory view showing a state in which a liquid antifreeze supplying apparatus according to an embodiment of the present invention is arranged on a road, and FIG. 2 is an explanatory view showing an entire configuration of the liquid antifreeze supplying apparatus of the present invention. . Here, the liquid antifreeze supply apparatus of the present invention is
A storage unit 1 for storing the liquid antifreezing agent 26, a sensor unit 5 for detecting various external conditions, a control unit 3 for controlling the supply amount and the supply amount according to the detection results of the sensor unit 5, and a roadside An injection nozzle unit 4 that is installed and supplies the liquid antifreeze agent 26 to the road surface, a liquid supply unit 2 that supplies the liquid antifreeze agent 26 from the storage unit 1 to the injection nozzle unit 4, the liquid supply unit 2, and a sensor Unit 5, display unit 6, communication unit 7, and power supply unit 30 for driving control unit 3, wherein liquid supply unit 2 is intermittent pumping means such as pump 10, and electric motor that opens and closes a pipeline. The injection nozzle unit 4 includes a valve 11, the injection nozzle unit 4 includes a universal joint capable of adjusting the injection direction, and the liquid supply unit 2 and the injection nozzle unit are connected by connecting the liquid supply unit 2 and the injection nozzle unit 4 with a liquid supply pipe 21. 4 can be separated from each other.

貯留部１の貯留タンク９と液供給部２は給液管２０でのみ接続されているので、貯留部１と液供給部２とを互いに離して設置することが出来る。   Since the storage tank 9 and the liquid supply unit 2 of the storage unit 1 are connected only by the liquid supply pipe 20, the storage unit 1 and the liquid supply unit 2 can be installed apart from each other.

液供給部２は、液状凍結防止剤２６を噴射ノズル部４へ間欠で圧送するための、リリーフ弁付ポンプ１０又はポンプとリリーフ弁を備えている。また、噴射ノズル部４への管路を開閉する噴射電動弁１１を備えている。また液供給部２と噴射ノズル部４は送液管２１のみで接続されているので、液供給部２と噴射ノズル部４を離して設置することが出来る。さらに、液供給部２と制御部３は制御配線２２でのみ接続されているので、液供給部２と制御部３を離して設置することもできる。   The liquid supply unit 2 includes a pump 10 with a relief valve or a pump and a relief valve for intermittently feeding the liquid antifreezing agent 26 to the injection nozzle unit 4. Moreover, the injection electric valve 11 which opens and closes the pipe line to the injection nozzle part 4 is provided. Moreover, since the liquid supply part 2 and the injection nozzle part 4 are connected only by the liquid feeding pipe 21, the liquid supply part 2 and the injection nozzle part 4 can be installed separately. Furthermore, since the liquid supply part 2 and the control part 3 are connected only by the control wiring 22, the liquid supply part 2 and the control part 3 can also be installed separately.

制御部３は、路面上を通過する車両を検出する車両通過検知センサー１４及び外気温度を検出する気温センサー１５や気象観測センサー１６から成るセンサー部５とセンサー用制御配線２３で接続され、センサーの検出結果と噴射条件設定に応じて、路面への供給及び供給量を制御している。また、液状凍結防止剤２６の残液量や運転中や停止中等を表す表示部６が表示用配線２４で接続されている。更に、通信部７と通信配線２５で接続され、遠隔監視制御部８のパソコンや携帯電話１９と運転状況や運転指令等の通信を行うことができる。   The control unit 3 is connected to a sensor unit 5 including a vehicle passage detection sensor 14 that detects a vehicle passing on the road surface, an air temperature sensor 15 that detects an outside air temperature, and a weather observation sensor 16, and a sensor control wiring 23. The supply to the road surface and the supply amount are controlled according to the detection result and the injection condition setting. In addition, a display unit 6 that indicates the remaining liquid amount of the liquid antifreezing agent 26, operation, stoppage, and the like is connected by a display wiring 24. Furthermore, it is connected with the communication part 7 by the communication wiring 25, and can communicate with a personal computer and the mobile telephone 19 of the remote monitoring control part 8 about a driving condition, a driving command, etc.

噴射ノズル部４は液状凍結防止剤２６を路面上に噴射する噴射ノズル１３と噴射ノズル１３の噴射角度を調整する自在継ぎ手１２から構成されている。   The injection nozzle unit 4 includes an injection nozzle 13 that injects the liquid antifreezing agent 26 onto the road surface, and a universal joint 12 that adjusts the injection angle of the injection nozzle 13.

本発明に使用する液状凍結防止剤２６として、特に、乾燥した環境条件でも吸湿性に富み、結晶の析出が無くノズルの詰まりを防止出来る酢酸カリウム水溶液又は酢酸カリウム水溶液に多価アルコールを添加したもの又は蟻酸カリウム水溶液又は蟻酸カリウム水溶液に多価アルコールを添加したものを使用する。   The liquid antifreeze agent 26 used in the present invention is a potassium acetate aqueous solution or a potassium acetate aqueous solution which is rich in hygroscopicity even in dry environmental conditions and can prevent clogging of the nozzle without crystal precipitation. Alternatively, an aqueous potassium formate solution or an aqueous potassium formate solution added with a polyhydric alcohol is used.

本発明の液状凍結防止剤供給装置の具体的動作について説明する。図中で説明に不要な部分は記載を省略するとともに配線は破線、液流れの給液管、送液管は矢印で表示している。   The specific operation of the liquid antifreeze supplying apparatus of the present invention will be described. In the figure, portions unnecessary for explanation are omitted, wiring is indicated by broken lines, liquid flow supply pipes, and liquid supply pipes are indicated by arrows.

たとえば、外気温が下がり路面への液状凍結防止剤２６の供給を開始する条件になると、貯留タンク９に貯留してある液状凍結防止剤２６を液供給部２のリリーフ弁付きポンプ１０を駆動させて、噴射ノズル部４への送液を開始する。更に噴射ノズル部４への管路を開閉する噴射電動弁１１を開いて噴射ノズル部４から路面へ噴射される。   For example, when the outside air temperature drops and the condition for starting the supply of the liquid antifreeze agent 26 to the road surface is reached, the liquid antifreeze agent 26 stored in the storage tank 9 is driven to drive the relief valve pump 10 of the liquid supply unit 2. Then, liquid feeding to the spray nozzle unit 4 is started. Further, the injection motor-operated valve 11 that opens and closes the pipe line to the injection nozzle unit 4 is opened to inject the fuel from the injection nozzle unit 4 onto the road surface.

この時、液状凍結防止剤２６の噴射する場所は、噴射ノズル部４の自在継ぎ手１２で車両のタイヤの通過する位置２７に調整する。   At this time, the place where the liquid antifreezing agent 26 is sprayed is adjusted to the position 27 through which the vehicle tire passes by the universal joint 12 of the spray nozzle portion 4.

また、噴射ノズル部４から路面へ供給される液状凍結防止剤２６の液量は、リリーフ弁付きポンプ１０の吐出圧力、噴射電動弁１１の開放時間及び噴射ノズル１３の仕様によって決定される。   Further, the amount of the liquid antifreezing agent 26 supplied from the injection nozzle unit 4 to the road surface is determined by the discharge pressure of the pump 10 with a relief valve, the opening time of the injection motor operated valve 11, and the specification of the injection nozzle 13.

また、路面上を通過する車両を車両通過検知センサー１４が検出した場合は、リリーフ弁付きポンプ１０を停止させ、かつ、噴射電動弁１１を閉じて噴射を停止する。   Moreover, when the vehicle passage detection sensor 14 detects a vehicle passing on the road surface, the pump with the relief valve 10 is stopped, and the injection motor operated valve 11 is closed to stop the injection.

また、貯留タンク９に貯留していた液状凍結防止剤２６が減少すると、リリーフ弁付きポンプ１０の空運転防止の為に路面への液状凍結防止剤２６の供給を停止し表示部６に表示される。そして、液状凍結防止剤２６を補給すると運転を再開する。   When the liquid antifreezing agent 26 stored in the storage tank 9 decreases, the supply of the liquid antifreezing agent 26 to the road surface is stopped and displayed on the display unit 6 to prevent the pump 10 with a relief valve from running idle. The When the liquid antifreezing agent 26 is replenished, the operation is resumed.

更に、運転中や停止中等の装置の稼動状況や異常発生等を遠隔監視制御部８のパソコンや携帯電話１９に送信することができ、またパソコンや携帯電話１９から運転開始や停止及び設定変更等を行うことができる。   In addition, the operating status of the device during operation or stoppage, the occurrence of an abnormality, etc. can be transmitted to the personal computer or mobile phone 19 of the remote monitoring control unit 8, and operation start, stop, change of settings, etc. from the personal computer or mobile phone 19. It can be performed.

以上のように、本発明では、噴射により路面へ液状凍結防止剤を供給するため、路面工事の必要がなく、移設及び一時的な撤去が可能であり工事費を低減できる。   As described above, in the present invention, since the liquid antifreezing agent is supplied to the road surface by injection, there is no need for road surface construction, and relocation and temporary removal are possible, thereby reducing the construction cost.

また、噴射ノズル個々に噴射目標位置が噴射ノズル設置後にも行えるため、種々の路面及び様々な路面勾配への適応が可能であり、車両のタイヤの通過する位置に調整することで無駄な位置への散布を低減できる。   In addition, since the injection target position can be set for each injection nozzle even after the injection nozzle is installed, it can be applied to various road surfaces and various road surface gradients. Can be reduced.

また、酢酸カリウム水溶液又は酢酸カリウム水溶液に多価アルコールを添加したもの又は蟻酸カリウム水溶液又は蟻酸カリウム水溶液に多価アルコールを添加したものを使用することで、結晶の析出による噴射ノズルの詰まりを防止することができ保守点検が容易に行える。更に塩素成分を全く含まないので、橋梁や道路の鉄筋や環境への悪影響を与える虞が無い。また微生物による生物分解が可能であり、地球環境への影響が小さい。   Further, by using a potassium acetate aqueous solution or a potassium acetate aqueous solution added with a polyhydric alcohol, or a potassium formate aqueous solution or a potassium formate aqueous solution added with a polyhydric alcohol, the injection nozzle is prevented from clogging due to crystal precipitation. Maintenance and inspection can be performed easily. Furthermore, since it does not contain any chlorine component, there is no risk of adverse effects on bridges, road rebars and the environment. Biodegradation by microorganisms is possible and the impact on the global environment is small.

更に、本発明は上述の実施例に限定されることなく、特許請求の範囲の記載に基づいて種々の設計変更が可能である。   Furthermore, the present invention is not limited to the above-described embodiments, and various design changes can be made based on the description of the scope of claims.
