FIG. 1 is a configuration diagram showing a configuration of a mist spray system according to Embodiment 1 of the present invention. FIG. 2 is a diagram showing a state where the spray nozzle of the mist spray system is installed near the ceiling of the passage of the golf driving range.
The mist spraying system according to Embodiment 1 of the present invention is installed in order to lower the temperature around the bat at the golf driving range by taking a golf driving range as an example. In addition to the golf driving range, the facility can be applied to a temperature drop in a place where a large number of seats are arranged such as a batting center and a fishing pond. In addition, it is assumed that there are a plurality of bats at the driving range, and there are N bats in succession.

A mist spraying system 1 according to Embodiment 1 of the present invention includes, as shown in FIG. 1, a pressurized water supply device 5 that pressurizes and feeds water, and a main water distribution pipe through which water fed from the pressurized water supply device 5 flows. 2, the main branched from the water pipe 2 is child water pipe ₄ a to 4 _N, spray nozzle 3 connected to the tip of the child water pipe ₄ a to 4 _N, switching control for opening and closing the child water pipe ₄ a to 4 _N Valves 6 _{a to} 6 _N are provided. Note that water is supplied from the water supply 7 to the pressurized water supply apparatus 5.

The pressurized water supply device 5 includes a high-pressure pump 11 that pressurizes water, a main valve 12 that supplies water supplied from the high-pressure pump 11 to the main water distribution pipe 2, and a drain valve that is opened when the water pressure in the main water distribution pipe 2 is reduced. 13 comprises the switching control valve ₆ a to 6 _N and the high-pressure pump 11, main valve 12, a mist control panel 14 which controls the drain valve 13.

The main water pipe 2 is supported by the ceiling behind the batting bat as shown in FIG.
The child water distribution pipe 4 is branched from the main water distribution pipe 2 and extends horizontally toward the front, and the tip thereof is inclined at a predetermined angle of 22.5 degrees. For example, it may be 45 degrees because of procurement.
The spray nozzle 3 is inclined so that the central axis bows 22.5 degrees. The installation altitude of the spray nozzle 3 is, for example, 4 m. In addition, although the installation altitude of the spray nozzle 3 should be determined depending on the average particle diameter and the maximum particle diameter of the mist, it may be set according to the situation of the installation place.

  As shown in FIG. 3, the mist control panel 14 includes a storage means 21 in which a predetermined time for starting the operation of the mist spraying system 1 and a time for ending the operation are stored, and a spray nozzle corresponding to each bat. And control means 22 for controlling the start and stop of spraying of mist from 3. The mist control panel 14 has an internal clock 23.

FIG. 4 is a flowchart showing a procedure in which the mist control panel 14 controls the mist spraying system 1 to start and stop mist spraying.
Next, a procedure in which the mist control panel 14 controls the mist spraying system 1 to start and stop mist spraying will be described. A signal line from a thermohygrometer (not shown) is connected to the mist control panel 14, and the mist control panel 14 automatically sprays mist only when the temperature and humidity satisfy predetermined conditions. In addition to this, it may be started and stopped at a predetermined time every day by a timer or the like. The following procedure is a procedure when the temperature and humidity satisfy predetermined conditions and mist can be sprayed. When the temperature or humidity does not satisfy the predetermined condition, the mist is not sprayed even if the batting is used.

  In step S101, the mist control panel 14 determines whether or not it is time to start operation of the mist spraying system 1, and proceeds to step S102 if it is time to start operation, and repeats step S101 if it is not time to start operation.

In step S102, the mist control panel 14 opens the main valve 12 and simultaneously opens the drain valve 13.
Next, in step S <b> 103, the mist control panel 14 turns on the high-pressure pump 11 and supplies pressurized water to the main water distribution pipe 2. Then, the air remaining in the main water distribution pipe 2 is pushed out together with the water from the drain valve 13, and a uniform water pressure is applied in the main water distribution pipe 2.
Next, in step S104, the mist control panel 14 closes the drain valve 13, and the water pressure in the main distribution pipe 2 reaches a desired water pressure, for example, 6 MPa.

Next, in step S105, the mist control panel 14 determines whether or not there is a new application for using the bat at the reception system 15. If there is a new application, the process proceeds to S107, and if there is no new application, S106. Proceed to
In step S106, the mist control panel 14 determines whether or not the use of the at-bat is completed from the reception system 15, and proceeds to S108 if there is an end of use and proceeds to S109 if there is no end of use.
In step S107, the mist control panel 14 opens the opening / closing control valve 6 corresponding to the bat where the new application for use is made, and proceeds to S109. Then, pressurized water is supplied to the spray nozzle 3 via the sub-distribution pipe 4. In this way, the mist is sprayed from the spray nozzle 3 corresponding to the bat where the use starts, and the vicinity of the bat is cooled.
In step S108, the mist control panel 14 closes the opening / closing control valve 6 corresponding to the bat where use has ended, and proceeds to S109. Then, water supply to the spray nozzle 3 of pressurized water is stopped, and spraying of mist is stopped.

In step S109, the mist control panel 14 determines whether or not it is time to end the operation of the mist spraying system 1. If it is time to end the operation, the process proceeds to S110.
In step S110, the mist control panel 14 opens the drain valve 13 to reduce the water pressure in the main water distribution pipe 2.
In step S111, the high-pressure pump 11 is turned off after about 3 seconds from the opening of the drain valve 13, and then the main valve 12 and the drain valve 13 are closed.

Thus, according to the first embodiment, since the mist is sprayed from above and behind the bat and the mist evaporates, heat is taken from the surrounding air to cool the air and flow the downward air flow to the bat. A mist spraying system that consumes less power can be obtained.
In addition, since mist is sprayed only around the used bats and mist is not sprayed on unused bats, the power and water consumed by the mist spraying can be saved.

  In the first embodiment, the mist control panel 14 is controlled to open and close the open / close control valve 6 in accordance with the presence or absence of a batting user while the system is activated. As a modification, the mist control panel 14 is a system. During startup, it is possible to basically spray the whole, and it is possible to acquire the spray stop by the user from the reception system 15 and open / close the open / close control valve 6. In this case, the temperature lowering effect can be obtained efficiently by spraying mist widely.

The mist control panel 14C according to the third embodiment of the present invention has three open / close control valves corresponding to the bats adjacent to the right and left of the bat when there is a new application for the use of the bat from the reception system 15 6 is opened and pressurized water is supplied to the three spray nozzles 3. In the case of a bat at the end, in addition to the bat, the two open / close control valves 6 corresponding to the bats adjacent to either the right or left of the bat are opened to supply pressurized water to the two spray nozzles 3. .

As described above, according to the third embodiment, since the mist is sprayed from the spray nozzle 3 corresponding to not only the hitting bat to be used but also the adjacent batting bat, the air temperature is lowered in a more spot-like manner. There is an effect that the temperature can be lowered more effectively.
Moreover, even if a little wind blows, the temperature at the bat used can be surely lowered.

When another person uses a bat adjacent to the bat used, the intention of the other person is given priority. For example, the bat _{9i + 2} is used first, and at that time, the mist is sprayed from the spray nozzles 3 corresponding to the three bats 9 of the bat _{9i + 1} and _{9i + 3} adjacent to the bat _{9i + 2} . Next, when another person uses the bat 9 _{i + 1} and does not want to lower the temperature, the spraying of the mist from the spray nozzle 3 corresponding to the bat 9 _{i + 1} is stopped.

  In the third embodiment, the mist is sprayed toward the batting bat that is used and the batting bat that is adjacent to the right and left to be used. Alternatively, mist may be sprayed.

In the second embodiment and the third embodiment as well, a mist control panel that performs opening / closing control by stopping spraying by the user may be used based on the entire spray.
