  Embodiments of the present invention will be specifically described below based on the embodiments of the present invention illustrated in the accompanying drawings.

  In the accompanying drawings, FIGS. 1 to 9 show an embodiment of the present invention, and FIG. 1 is an overall side view showing an example in which a shutter of a building is washed with water using a van-type automobile for cleaning work. 2 is an overall side view in which a part of the automobile is broken, FIG. 3 is an enlarged view taken along arrow 3 of FIG. 2 in which the vehicle ceiling is not shown, and FIG. 4 is a view in which the tail gate is not shown. 4 is an enlarged view taken along arrow 5 in FIG. 2, FIG. 6 is an enlarged sectional view taken along line 6-6 in FIG. 3, and FIG. 7 is an enlarged sectional view taken along line 7-7 in FIG. 8 is a view taken in the direction of arrow 8 in FIG. 7, and FIG. 9 is a piping diagram showing an example of piping between the pump and the tank.

  First, in FIG. 1, a van van V for cleaning work has a box-shaped vehicle body F called a so-called one-box type, and a vehicle compartment C formed in the vehicle body F includes a passenger compartment Cf, It is composed of a cargo compartment Cr which is continuous to the rear side of the passenger compartment Cf and whose rear end is open to the rear surface of the vehicle body F. In the front passenger compartment Cf, two rows of front and rear seats Sf and Sr are juxtaposed at an interval in the front and rear, and the back portion of each of the seats Sf and Sr can swing back and forth. If the backrest portion of the rear row sheet Sr is tilted forward, a temporary extended cargo space can be formed on the front side of the cargo space Cr. The rear end opening of the cargo compartment Cr can be opened and closed by a tailgate G pivotally supported on the upper rear end of the vehicle body F. The tailgate G is connected to the cargo compartment Cr. When in the closed position for closing the rear end opening, the outer peripheral edge of the inner surface of the gate is in pressure contact with the rear end opening edge of the vehicle body F via a seal packing (not shown), and rain, dust, etc. It does not enter the cargo compartment Cr (so that the sound in the passenger compartment C does not leak outside). The above is the same as the cabin configuration of a conventional van type automobile for carrying cargo.

  A base plate B made of a flat metal plate (stainless steel plate in the illustrated example) for mounting the cleaning device of the present invention is detachably fixed to the upper surface of the vehicle body floor Ff facing the cargo compartment Cr by fixing means such as bolts. The On the base plate B, a tank T that is arranged adjacent to the rear side of the rear row sheet Sr and stores water, a pump P that can suck water in the tank T, and the pump P that drives the pump P And an exhaust silencer M interposed in the middle of an exhaust pipe Ex extending from the internal combustion engine E is housed and fixed. The exhaust silencer M is provided separately from the small exhaust silencer MX originally provided in the exhaust system of the internal combustion engine E and on the exhaust downstream side in order to enhance the exhaust silencer effect. In the illustrated example, a stainless steel sound absorbing material is housed in a stainless steel silencer. In addition, an insulator for heat insulation is wound around the outer peripheral surface of the exhaust pipe Ex so that the exhaust pipe Ex that becomes high temperature during operation of the internal combustion engine E does not come into direct contact with the equipment in the cargo compartment Cr.

  In particular, in the illustrated example, an internal combustion engine E and a plunger pump P that is directly connected to the internal combustion engine E are mounted together in a common machine frame 1 with wheels W and unitized. An appropriate place of the frame 1 is detachably fixed to a floor portion Ff (base plate B in the illustrated example) of the vehicle body F by a fixing means such as a bolt. If the pump P and its drive system (internal combustion engine E) are unitized in this way, they can be stored compactly and comfortably in the cargo compartment Cr. Also, if the machine frame 1 is removed from the vehicle body floor Ff, the pump P and its drive system are moved as close as possible to an arbitrary water source outside the vehicle when the tank T is empty and water cannot be supplied. It can be used as a water supply means (pumping means) for the water source, which is convenient. It is also possible to perform water washing operations using the water from the water source. Although not clearly shown in the drawings, the exhaust silencer MX and the exhaust pipe Ex are detachably connected. Accordingly, as described above, the internal combustion engine E and the pump P are connected together with the machine frame 1. When taking it out of the vehicle, the exhaust silencer MX and the exhaust pipe Ex can be disconnected at any time.

  A pressure feed pipe insertion portion Ha for inserting a pressure feed pipe A extending from the discharge side of the pump P into the floor portion Ff below the cargo compartment Cr of the vehicle body F and pulling the pressure feed pipe A out of the vehicle, An exhaust pipe insertion portion Hb is provided for allowing the exhaust pipe Ex downstream of the exhaust silencer M to pass through and opening the downstream end of the exhaust pipe Ex to the atmosphere outside the vehicle. The pressure feed tube insertion portion Ha includes a first insertion hole h formed in the floor portion Ff of the vehicle body F, a first plate hole Bh formed in the base plate B corresponding to the insertion hole h, and the plate hole. The upper end is fixed to the opening edge of Bh (welded in the illustrated example) and extends downward through the first insertion hole h (through the floor portion Ff). The pumping tube A having flexibility is passed through. Further, the exhaust pipe insertion portion Hb is formed on the base plate B corresponding to the second insertion hole h ′ formed in the floor Ff of the vehicle body F at a distance from the first insertion hole h, and the insertion hole h ′. The upper end of the second plate hole Bh ′ that is drilled and the upper edge of the plate hole Bh ′ is fixed (welded in the illustrated example), and passes through the second insertion hole h ′ (through the floor portion Ff) and downward. The exhaust pipe Ex having flexibility is passed through the cylindrical body 2 '.

  In the illustrated example, the first cylindrical body 2 is formed shorter than the second cylindrical body 2 ′. However, in the present invention, the first cylindrical body 2 may be formed longer than the second cylindrical body 2 ′, or You may form in the same length. Further, in the illustrated example, with the exhaust pipe Ex inserted through the exhaust pipe insertion portion Hb, the downstream end of the exhaust pipe Ex protrudes outward from the lower end of the second cylindrical body 2 'so that the exhaust heat is transmitted to the vehicle body. In the present invention, the downstream end of the exhaust pipe Ex may be retained in the second cylindrical body 2 ′.

  In this way, the pressure feed pipe insertion portion Ha and the exhaust pipe insertion portion Hb are fixed to the floor portion Ff of the vehicle body F at a distance from each other and extend downward through the floor portion Ff. Therefore, it is possible to easily form a straight pipe insertion portion up and down without significantly modifying the floor portion Ff of the vehicle body F.

  Further, the pressure feed pipe insertion portion Ha is provided with a first opening / closing means va capable of opening / closing it arbitrarily, and the exhaust pipe insertion portion Hb is provided with a second opening / closing means vb capable of opening / closing this arbitrarily. The first opening / closing means va includes a first valve plate 6 that is pivotally supported by the base plate B and is rotatable between a closed position that closes the first plate hole Bh and an open position that opens the hole Bh, and the valve And locking means 7 capable of fixing the plate 6 to the closed position and the open position, respectively. The second opening / closing means vb is pivotally supported by the base plate B, and a second valve plate 6 ′ that is rotatable between a closed position that closes the second plate hole Bh ′ and an open position that opens the hole Bh ′. And a locking means 7 'capable of fixing the valve plate 6' in the closed position and the open position, respectively. In the illustrated example, the locking means 7 and 7 'are constituted by wing screws that can be screwed into the valve plate and press-contacted to the base plate B.

  In this way, by providing the opening / closing means va and vb that can arbitrarily open and close the pressure feed tube insertion portion Ha and the exhaust tube insertion portion Hb, the pressure feed tube insertion portion Ha and the exhaust gas can be used during normal traveling without cleaning work. By closing the tube insertion portion Hb, it is possible to reliably prevent external dust and splashes from entering the cargo compartment from these insertion portions.

  Further, a U-shaped guide support portion 8 is integrally formed at the rear end lower portion of the vehicle body F in a rear view of the vehicle, which can guide and support the middle of the pressure feed tube A drawn out of the vehicle through the pressure feed tube insertion portion Ha. Is provided. As a result, it is possible to accurately turn the pumping pipe A drawn downward to the outside of the vehicle through the pumping pipe insertion portion Ha. For example, as described later, road washing is performed while the automobile V is moved little by little. In this case, it is possible to avoid a situation in which the pumping tube A drawn downward is rubbed strongly against the ground, and the durability of the pumping tube A is improved.

  One end of a flexible extension pipe 4 is detachably connected via a joint 3 to the downstream end of the pressure feed pipe A drawn out of the vehicle through the pressure feed pipe insertion portion Ha, and the other end of the extension pipe 4 The spray gun SG is detachably connected through the joint 5. Thus, the downstream end of the pressure feeding pipe A is detachably connected to the spray gun SG via the joints 3 and 5 and the extension pipe 4 in the illustrated example, but the portion of the pressure feeding pipe A that is drawn out of the vehicle is sufficiently long and When the work site is close to the vehicle V, the spray gun SG may be directly connected to the downstream end of the pressure feed pipe A via a joint (that is, not via the extension pipe 4). When the distance from the site is relatively long and the extension pipe 4 is not sufficient, another extension pipe (not shown) may be added between the extension pipe 4 and the spray gun SG. . In any case, since the downstream end of the pressure feeding tube A can be directly attached to or detached from the spray gun SG or indirectly through an extension tube, the pressure feeding tube A itself is separated from the spray gun SG. (In other words, without being disturbed by the spray gun SG), it can be inserted through the pressure feeding tube insertion portion Ha without difficulty.

  The tank body Tm of the tank T is formed in a rectangular parallelepiped shape from a stainless steel plate in the illustrated example, and a water supply port Tc with a cap that can be opened and closed is provided on the upper surface of the tank body Tm. Water is supplied into the tank T by inserting a hose connected to a water supply source (for example, water supply) from the water supply port Tc with the cap open.

  In addition, the tank T is installed in the vehicle body F so that the height of the tank body Tm is lower than the height of the rear row seat Sr, and the left and right center pillars of the vehicle body F are integrated between the left and right center pillars. Is set to be lower than the installation height of the crossbar 9 coupled to. As a result, even when the tank T is installed in the cargo compartment Cr, it is possible to sufficiently ensure a rear view during driving of the vehicle, and the vehicle center of gravity can be arranged at a position as low as possible to improve running stability.

  In the tank T, there are provided a plurality of wave-dissipating plates 10 that are fixed in the tank T at intervals and suppress the flow of water in the tank T. As a result, the water in the tank T can be effectively reduced by the wave-dissipating action of the wave-cancelling plate 10 while the water in the tank T is oscillated, in particular, rolling while the vehicle is traveling, so that the traveling stability can be improved.

  Further, in the tank T, a water level indicator L for displaying the amount of stored water is disposed at a position facing the rear end opening of the cargo compartment Cr, and accordingly, visible to the operator from the rear end opening. The water level meter L is configured by accommodating the float 30 in a transparent vertical thin tube 31 whose upper and lower ends communicate with the upper and lower portions in the tank T so as to be movable up and down. The float 30 is provided to make the detected water level stand out, and is given a predetermined color so that an operator can easily see it. Therefore, the amount of remaining water can be easily confirmed without looking into the water supply port Tc from the top in order to confirm the amount of remaining water in the tank T in the cargo compartment Cf. The efficiency is improved, and the operator can predict to some extent when the water in the tank T will be exhausted by the water level gauge L, so that the water washing operation can be performed with a sense of security.

  Further, a reinforcing frame 23 that also serves as a reinforcing means for the front wall is fixed to the front wall of the tank T so as to project into a gap space between the front wall and the rear row sheet Sr. Between the front wall of the tank T and the tank T, a slit-like support space 23s is formed for inserting and supporting an on-vehicle equipment (not shown) (for example, a cleaning tool such as a brush used for cleaning work) so that it can be inserted and removed.

  Next, the piping configuration among the tank T, the pump P, and the spray gun SG will be described with reference to FIG. On the suction side of the pump P, one end of the suction pipe 11 is detachably connected via a joint, and the other end of the suction pipe 11 communicates with the tank T. On the other hand, on the discharge side of the pump P, one end of the pressure feeding pipe A is detachably connected via a joint, and the other end of the pressure feeding pipe A is connected to the spray gun 5 via the extension pipe 4 and the joints 3 and 5. Is done.

  In the middle of the pressure feeding pipe A, there is provided a relief valve R for returning the discharged water to the tank T side when the discharge pressure of the pump P exceeds the set pressure. Therefore, the spray gun 5 is temporarily operated during the pump operation. In a non-use state, the discharge water of the pump P is returned to the tank T side via the relief pipe Ra by opening the relief valve R, and an overload of the pump P can be avoided.

  Further, a drain pipe 13 with an on-off valve 12 is connected to the bottom of the tank T or the vicinity thereof, and this drain pipe 13 is flexible and is normally closed by the on-off valve 12. In addition, the water in the tank T can be discharged from the drain pipe 13 by gravity by arbitrarily opening the on-off valve 12. Thus, the drain pipe 13 and the on-off valve 12 constitute the drainage means D of the present invention for arbitrarily draining the water in the tank T outside the vehicle in cooperation with each other.

  A branch pipe 14 communicating with the suction pipe 11 is branched from the middle of the drain pipe 13, and an on-off valve 15 is provided in the middle of the branch pipe 14. Thus, by opening the on-off valve 15, the pump P can be started smoothly and reliably by supplying priming water to the suction side when the pump P is started.

  Further, a drain pipe 16 is branched from the middle of the pressure feed pipe A (upstream side of the relief valve R), and an open / close valve 17 that can be arbitrarily opened and closed is provided in the middle of the drain pipe 16. When the on-off valve 17 is opened while the pump P is in operation, the water in the tank T can be quickly discharged to the outside through the drain pipe 16.

  In the cargo compartment Cr, on the left and right sides of the tank T, various pipes used in the cleaning apparatus of the present invention, such as the pressure feeding pipe A, the extension pipe 4, the suction pipe 11, the discharge pipe 13, and the like are wound and held. A tube holding means 20 is provided. On the other side of the tank T, a gun holding means 21 that can hold the spray gun SG as a water spray means in a fixed position and detachably is provided. In the illustrated example, the gun holding means 21 is formed in a sheath shape that can be inserted and removed so that the elongated barrel portion of the spray gun SG can be inserted and removed, and is inclined rearwardly. It is appropriately determined from the viewpoint of stabilizing the support to the gun SG and facilitating the insertion / removal operation of the spray gun SG from the rear side of the cargo compartment Cr. 6, in addition to the gun holding means 21, a sheath-like gun holding means 21 'capable of inserting and supporting a spray gun SG' having a relatively short barrel is removably inserted. Alternatively, it may be provided instead.

  In the illustrated example, the pipe holding means 20 is constituted by a hook member fixedly supported on the vehicle body F on one side of the tank T, and the gun holding means 21 is a gun holder fixedly supported on the left and right other side walls of the tank T. Consists of. Due to the special arrangement of the holding means 20 and 21, when not in operation, the pipes separated from the tank T and the pump P can be wound compactly and held neatly, and the spray gun SG can be held stably and accurately without play. It is easy to store and manage the equipment.

  Next, the operation of the embodiment having the above configuration will be described. When the cleaning work van type automobile V of the present invention is used to wash a portion to be cleaned, for example, the shutter SH of the building, the van type automobile V is moved to the vicinity of the cleaning work place with the tank T filled with water. To stop and open the tailgate G. Next, various on-vehicle pipes, for example, the pressure feeding pipe A, the suction pipe 11, the discharge pipe 13, and the like are connected to a predetermined portion in the pipe form shown in FIG.

  In this case, the pressure feeding pipe A having one end connected to the discharge side of the pump P is pulled out of the other end through the pressure feeding pipe insertion portion Ha, and the extension pipe 4 and the joints 3 and 5 are connected to the downstream end of the pressure feeding pipe A. Connect the spray gun SG. On the other hand, the exhaust pipe Ex downstream of the exhaust silencer M is opened to the atmosphere outside the vehicle (in the illustrated example, the space between the lower surface of the vehicle body F and the ground) through the exhaust pipe insertion portion Hb.

  Thereafter, if the internal combustion engine E is started, the pump P is driven. Therefore, the tailgate G is closed as it is, and the worker performs the water washing operation with the spray gun SG in his hand in that state. In this water cleaning operation, high-pressure water is sprayed from the spray gun SG onto the portion to be cleaned, so that the contamination of the portion to be cleaned is quickly and efficiently washed away. In addition, it is also possible to perform the water washing operation with the water that is directly ejected from the downstream end of the pressure feeding pipe A without connecting the spray gun SG to the downstream end of the pressure feeding pipe A drawn out of the vehicle.

  Thus, according to the present embodiment, since the water washing operation can be performed using the water that comes out of the pressure feed pipe A drawn out of the vehicle from the pressure feed pipe insertion portion Ha, the water source that can be easily used is close. It is possible to easily perform water cleaning work even on a portion to be cleaned. Further, even when the tailgate G and the door and window of the automobile V are all closed during the water washing operation, exhaust of the exhaust from the internal combustion engine E and extraction of the pressure feed pipe A extending from the pump P can be performed without any trouble. When the internal combustion engine E is operated for the water washing operation and the pump P is driven, the tail gate G and the doors and windows of the automobile V are all closed, so that the pump P and the internal combustion engine in the cargo compartment Cr are closed. The engine E can be effectively shut off from the outside, so that the operation sound of the pump P and the operation sound of the internal combustion engine E during the cleaning work are greatly transmitted to the outside of the vehicle in combination with the noise reduction effect by the exhaust silencers M and MX. Therefore, the cleaning operation can be performed without any trouble even in a work place such as a residential area where quietness is required or in a work time zone such as midnight where quietness is required.

  In addition, since the cleaning operation can be performed with all the doors and windows of the tailgate G and the automobile V closed, the tailgate G and the doors and windows of the automobile V can be opened when the worker is working away from the vehicle. Since the tailgate G and the doors can all be closed and locked, it is possible to effectively prevent equipment in the vehicle from being stolen or mischievous.

  Further, the tank T is provided with a drainage means D for arbitrarily draining the water in the tank T to the outside of the vehicle. Water can be supplied flexibly up to any location. That is, since the cleaning vehicle V can be used as a simple water supply vehicle whenever necessary (conversion), it can be effectively used as a simple water supply means to a place where water is insufficient, such as a disaster occurrence place. .

  In the present embodiment, the front and rear rows of seats Sf and Sr are disposed in the passenger compartment Cf of the van-type automobile V for the cleaning operation, and the tank T is disposed adjacent to the rear side of the row seats Sr thereafter.
