Abstract

<P>PROBLEM TO BE SOLVED: To reduce the heat-island effect acknowledged today as a problem by remodeling a public bus operated during daytime with few passengers or a sightseeing bus with comparatively few passengers such that they can continuously or intermittently sprinkle water on a traveling road surface appropriately. <P>SOLUTION: A part of or all the backmost seats in the public bus or sightseeing bus are removed, and a water storage tank is arranged in an empty space. Water stored in the water storage tank is sprinkled continuously or intermittently on the road from a vehicle rear part through a discharge pipe. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a passenger bus having a watering function.

  Currently, not only large cities such as Tokyo, Nagoya, Osaka, but also local cities, heat island phenomenon has increased due to the problems of building forests and land surface coverage due to the progress of urbanization, which has caused global warming. This is one of the major reasons for the promotion.

As measures to mitigate this heat island phenomenon, it is considered to promote greening of the rooftops and wall surfaces of buildings and to make roads paved with water retention, but the spread is still not sufficient. On the other hand, conventional garbage trucks are used exclusively for the purpose of collecting and cleaning dust on roads, but their frequency of use is low, so they are not used for special purposes. It does not contribute.
On the other hand, it has been known that the outdoor temperature can be lowered to some extent by watering the entrance road at home in the summer in accordance with the old custom.
ACT 6-87420

  Buses in urban areas are intended to transport passengers along the route, but the majority of them are concentrated in the morning and evening commuting hours, whereas in the daytime The number of passengers is very small and the car is operated in a quiet state.

  In view of the above-described situation, the present invention selects a hot bus during the daytime for a traveling bus with a small number of passengers in the daytime or a sightseeing bus with a relatively small number of passengers, and appropriately supplies water to the traveling road surface. Can be sprayed continuously or intermittently to help mitigate the heat island phenomenon, which is a problem today.

  The present invention uses part or all of the rearmost seat of a traveling bus, a sightseeing bus, etc., installs a water storage tank in the part, and appropriately stores the water stored in the water storage tank through the discharge pipe at the rear of the vehicle body. A feature is that the water is continuously or intermittently sprinkled on the road.

The shower is not only the rear side of the vehicle body may be none shall be sprinkled into the outside of the vehicle body of the ceiling surface, Although storage tank volume is generally done with 2m ³ ~6m ^3, the shape is a bellows The tank volume can be changed as appropriate by making the shape stretchable.

  According to the present invention, a fixed-volume water storage tank is arranged in the rear seat of the bus to appropriately have a watering function outside the vehicle body, thereby enabling operations such as a patrol bus and a sightseeing bus during the daytime with few passengers. By effectively utilizing the water, it is possible to spray water on hot roads at any time during the day to help alleviate the heat island phenomenon. At this time, tap water may be used, but in general, each bus company installs a rainwater receiving tank outside the garage and uses such water during operation. It is made.

  In the present invention, when the water storage tank can be extended and contracted, it is convenient for contracting the water storage tank so that it does not get in the way during morning and evening rush hours so that a normal seat can be secured as much as possible.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a cross-sectional plan view showing the inside of the passenger bus 1. 2 is a seat, 3 is a water storage tank installed on the rear side. The water storage tank 3 is installed in a part or all of the rear seat, and is expanded as shown by a one-dot chain line in the drawing. For this purpose, it is convenient to form the tank in a bellows shape. In the illustrated example, the tank is shown to expand and contract to the left and right in the center. However, the tank may be arranged to be moved to either the left or right side.

  FIG. 2 is a partially broken front view of the above, and shows a state where water is sprayed from the water storage tank 3. In the drawing, 4 is a water supply pipe port from the outside to the water storage tank 3, and 5 is a water spray pipe so that water in the water storage tank 3 can be appropriately sprayed from the inside of the vehicle body to the road at the rear of the vehicle body by a valve operation (not shown). Made. In the present invention, in addition to manually opening and closing the above-mentioned watering, an automatic on-off valve that operates with a timer or the like is adopted, and it is continuously selected from the driver's seat under appropriate setting conditions, that is, selecting time and place. Or it can be made to water intermittently.

The volume of water tank 3 described above can be arbitrarily set, made exclusively that of 2m ³ ～6M ³ consider placing in the back seat.

  In the above embodiment, the water spraying is performed directly on the road from the rear side of the vehicle body. However, in the present invention, as shown in FIG. 3, the water in the water storage tank 3 is guided to the ceiling surface outside the vehicle body via a pumping pump (not shown). You may make it sprinkle at a point. 6 is a watering nozzle, and the water sprayed is useful for cooling the vehicle body, and indirectly is led from the eaves 7 provided on the outer peripheral surface to the rear side of the vehicle body and sprayed down on the road surface as in the previous example. It becomes.

  In the present invention, the water supply in the water storage tank 3 is performed when the bus returns to the garage, but if there is a place where water such as a river can be easily taken on the traveling route, such a place is provided. By selecting and installing several water stations, it will be possible to contribute to alleviating the heat island phenomenon in midsummer through smooth and effective operation. According to the experiment results of the present inventor, it has been found that the decrease in road surface temperature due to watering is 2 ° C. or less, and the above-mentioned effects are extremely remarkable, especially because the traveling bus is operated regularly. It will be a thing.

  In the present invention, the water storage tank 3 is removed in the winter when it is not in use, but without removing it, the hot water is stored in the winter and used for heating or on the road surface during snowfall. Sprinkling water and melting snow can be used.

It is a cross-sectional top view which shows the inside of the passenger bus which concerns on this invention. It is a partially broken front view of the passenger bus concerning the present invention. It is a use state figure of the passenger bus concerning the present invention.
