Description

  The present invention relates to water tanks (water distribution ponds, water purification ponds, water supply tanks) in water purification plants, sewage treatment plants, and water distribution / storage facilities, and water receiving tanks such as stores and condominiums, and in particular, access in automobiles (including motorcycles). The present invention relates to a water tank equipped with a water supply device capable of performing the above.

  Conventionally, water (raw water) taken from rivers and wells is sent to a water purification plant, treated with purified water, stored in a water purification pond, sent to a distribution pond by a pump, and then sent to each household. On the other hand, in the event of a disaster such as a typhoon, heavy rain, or earthquake, water intake facilities such as rivers and wells may be damaged or inundated, making it impossible to take water, or large amounts of water leaking from water pipes sent from distribution reservoirs to households In such a case, in order to secure the minimum necessary water (for example, water for firefighting or drinking water for residents), water supply from the water purification pond or distribution pond may be stopped.

  In such a case, the residents who have been cut off from the water supply try to secure drinking water by driving to a water purification plant or a distribution pond by car, etc. (I think that if you actually go to a water purification plant, you can get drinking water. There are also cases where people gather at water purification plants, etc.).

  However, clean water ponds and distribution ponds are unmanned, and water supply devices such as faucets are generally not installed for crime prevention. Therefore, even when urgent water supply is necessary at the time of the disaster, there is a problem that there is no means for supplying water to the water purification pond and the distribution pond, although there is water in the pond. Some water purification plants are equipped with facilities (fire hydrants, etc.) that can provide emergency water supply from fire ponds to fire trucks in the event of a disaster such as an earthquake, but residents cannot supply water directly from these fire hydrants. Also, the number and location of fire hydrants that can be supplied with water were limited.

  In general, automobiles do not approach the water purification pond or the distribution pond, and therefore, the design is not designed to allow many automobiles to come and go. Therefore, even if an emergency water supply means is installed in the water purification pond or distribution reservoir, there is a risk of causing heavy traffic congestion when residents come to the water purification plant or distribution reservoir by car in search of water in the event of a disaster. .

  The present invention has been made in view of the above points. The purpose of the present invention is to improve efficiency for users who ride in water purification tanks, distribution ponds, and other tanks by car when emergency water supply is required in the event of a disaster. An object of the present invention is to provide a water tank equipped with a water supply device that can be supplied by an automobile and can supply water in the water tank.

It is configured by installing two or more water supply devices with a gap. In addition to four-wheeled vehicles, vehicles include two-wheeled vehicles (motorcycles). According to the present invention, it is possible to easily and directly ride an automobile up to a position near each water supply device installed on the outer peripheral surface of the cylindrical water tank. For this reason, a user who brings in a general water supply tank of about 18L and supplies water can easily place the heavy tank on the automobile safely and with good workability.

  Moreover, the aquarium equipped with the water supply apparatus according to the present invention is a square aquarium installed on the ground or on the roof of a building or in a building, and on a plurality of surfaces of the square aquarium, It is configured by installing one or more water supply devices on each surface at an accessible interval. According to the present invention, it is possible to easily and directly ride a car up to a position near each water supply device installed on a plurality of surfaces of a square water tank. For this reason, a user who has supplied water with a general 18L tank can easily place the heavy tank on the automobile safely and with good workability.

  Here, it is preferable to install an emergency road for securing entry into and exit from each water supply device by an automobile at a position surrounding the periphery of the two or more water supply devices. If comprised in this way, the traffic jam of the motor vehicle which got on the water purification pond, the distribution reservoir, and other water tanks can be eased. Conventional water distribution ponds and water purification ponds are not designed on the premise that many cars will enter and exit for security reasons, so severe traffic congestion will occur when such a situation occurs, According to the present invention, most of the traffic jam can be alleviated.

  Furthermore, it is preferable that the emergency road is configured to include a vehicle traffic zone including a one-way road installed on the outer peripheral side and a stop water supply zone installed on the inner peripheral side. If comprised in this way, the traffic jam of the motor vehicle which got on the water purification pond, the distribution pond, and other water tanks can be relieve | moderated more effectively.

  Further, the loop-shaped water supply apparatus according to the present invention is provided with a loop-shaped water supply pipe formed in a loop shape by being drawn out from the water tank to the ground directly above or around the water tank installed underground. Two or more water supply devices are installed in the loop-shaped water supply pipe with an interval that can be accessed by an automobile. If comprised in this way, a motor vehicle can be directly mounted directly to the position near each water supply apparatus installed in the loop-shaped water supply pipe. For this reason, a user who has supplied water with a general 18L tank can easily place the heavy tank on the automobile safely and with good workability. By the way, this kind of emergency water supply device is not used at all at normal times. For this reason, it is necessary to perform regular maintenance (replacement of water in the water supply pipe, etc.) in order to prevent the occurrence of "water pool" etc., but in the present invention, the water supply pipe is configured in a loop shape. For example, the water in the entire loop-shaped water supply pipe can be replaced simply by draining water from one water supply device, and the maintenance can be easily performed.

  The water tank equipped with the water supply device and the loop-shaped water supply device can be used to treat and store water (raw water) taken from rivers and wells (raw water) and store it for distribution. It is suitable to apply to the whole system that distributes water etc.

  Moreover, the construction method of the aquarium equipped with the water supply apparatus according to the present invention includes the construction process of installing the water supply apparatus in an existing aquarium, and the emergency road that surrounds the aquarium in a site around the existing aquarium. And a construction process in which both ends of the emergency road are connected to public roads, one of which is an entrance and the other is an exit. According to this construction method, it is possible to easily update to a water tank equipped with the water supply apparatus according to the present invention simply by installing a water supply apparatus and a road around the existing water tank.
