In the present embodiment, the spray heads 18 are installed at intervals of 150 to 460 cm in the longitudinal direction of the water supply pipe 16. Another pipe 22 is provided along the outer wall of the roof 12 and the building 14 from the water supply pipe 16 to supply water to the water supply pipe 16. The pipe 22 is connected to the faucet 24 via a flexible hose 26. Alternatively, the pipe 22 may be connected to another pipe connected to another water source.

The cooling device (10) is connected to an electrically operated valve (28) to regulate the supply of water to the cooling device (10). The electrically operated valve 28 is connected to the controller 30 so that it is sequentially controlled by a controller 30 that electrically controls the operation timing of the valve. The controller 30 is connected to one or more suitable number of sensors 32 to initiate the operation of the controller 30. The controller is made up of programmable means for controlling the spray operation by a program desired by the user. The sensor 32 is mounted on the roof 12 to detect the temperature and humidity of the air around the roof 21. The controller (30) is connected to the sensor (32) to control the amount of water to be sprayed in accordance with the detection level of the sensor (32). The initial set value of the controller 30 is precisely set corresponding to the size of the roof 12 to be cooled, the size of the water spraying apparatus 10 itself, and the pressure of water used.

As shown in Figs. 2A to 2D, a base leg 34a is formed in each of the teeth pipes 34 that are separated from each other so as to protrude upward in a substantially vertical direction. The base leg 34a is a branch formed in the tee pipe 34 so as to face upward from the tee pipe 34.

An orifice 38 communicating with the water supply pipe 16 for spraying water onto the roof 12 by reducing the pressure of water supplied from the water supply pipe 16 is formed at a predetermined interval on the water supply pipe 16, The spray head 18 includes a nozzle 18f formed with an orifice 38 for spraying water to one side of the roof 12 by reducing the pressure of the water supplied from the water supply pipe 16 and an orifice A diffuser 40 which forms an outlet 40a so as to disperse the water sprayed from the nozzle 18f in a required direction on the roof and which is pressed against the nozzle 18f, An upper housing 48 threadedly coupled to the nozzle 18f to couple the upper housing 48 to the tee pipe 34 and to receive the threads 50a, 50b of the lower housing 50, , It consists of a packing 52 provided between the upper housing 48 and the lower housing 50 to prevent leakage of water supplied to the nozzle (18f) from the tee fittings 34.

The spray head 18 is installed in the water supply pipe 16 at a low height so as to avoid loss due to strong wind when water is discharged.

A normal filter 36 is installed between the branch pipe 48a of the upper housing 48 and the lower housing 50 to prevent the orifice 38 of the gasifier spray head 18 from being clogged by foreign matter. .

The diffuser 40 disperses the water collision surface 40b which collides with the water coming from the nozzle 18f and the water colliding with the water collision surface 40b to the required place of the roof 12, (40c) forming the outlet (40a) so as to guide the water not to contact the water, such as a transformer, a ventilator, and an antenna, which should not be exposed to water, And a cylindrical engaging portion 40d for urging the support leg 40c against the nozzle 18f.

As shown in FIG. 3, the water supply pipe 16 is supported by a support member 42 provided on the roof 12. The support member 42 is fixed to the support pipe 42 and is flexible so as to accommodate a change in the lateral direction of the water pipe 16 caused by a change in length of the water pipe 16 in accordance with a change in temperature, A protrusion 44 in the vertical direction is formed in the base 61. The support member 42 fixes the water supply pipe 16 by the flexible protrusion 44 and at the same time has a structural load that is caused by the weight of the water supply pipe 16 and the spray head 18 And the bottom surface is designed to be flat so as to be appropriately dispersed on the roof. A screw hole 58 is formed in the base 61 of the support member 42 to fix the support member 42 to the roof 12. The support member 42 is connected to the pipe 22 and the water pipe 16 is fixed to the support pipe 42 at a predetermined height to prevent the heat of the roof pipe 12 from being transmitted to the water pipe 16. [ A tuck 60 having a predetermined height D1 is formed.

4, the controller 30 for receiving a signal from the sensor 32 and controlling the spraying operation includes a programmable ROM (ROM) for storing a program and data desired by the user, A microcomputer for detecting a change in a climatic condition by receiving a temperature and a humidity signal and determining a water injection quantity required at a specific time of day, a frequency of a repetition cycle of the water injection, and an irrigation time according to the program and data stored in the programmable ROM Lt; / RTI >

The controller 30 is also connected to the sensor 32 to determine whether it should dwell on the surface of the roof 12 and how long to sprinkle water and periodically how much water should be sprinkled.

The power supply means 54 is connected to the controller 30 via an operation switch 56 to supply the DC voltage to the controller 30. [

The valve 28 supplies / blocks the water supplied from the faucet 24 to the water supply pipe 16 in accordance with the control signal outputted from the controller 30 and at the same time, Is connected to the controller (30) to regulate the amount of water supplied from the faucet (24) to the water supply pipe (16).

Hereinafter, the operation of the water sprinkling apparatus according to one embodiment of the present invention will be described.

It is assumed that the faucet 24 and the valve 28 are closed and the operation switch 56 is off, as shown in Fig. 1 as an initial condition for the operation explanation. It is assumed that the temperature around the building 14 is hot.

Next, after installing the cooling device 10, the user is prompted to initialize the controller 30 in response to the size of the roof 12 to be cooled, the size of the cooling device 10 itself, Set the setting value.

Next, the user turns on the operation switch 56 and opens the faucet 24. Water is then supplied from the faucet (24) to the valve (28) through the hose (26). Next, a DC voltage is output from the power supply means 54 to the controller 30. [

The temperature and humidity of the air above the roof 12 are then output to the controller 30 from the sensor 32.

Then, the controller 30 determines the water injection amount required for cooling the roof 12, the frequency of the repetition period of the water injection, and the irrigation time.

A control signal is then output from the controller (30) to the valve (28). The valve 28 is then opened. Then, water is supplied to the water supply pipe (16) through the pipe (22). The water supplied to the water supply pipe (16) is supplied to the ordinary filter (36) through the teething pipe (34). The pressure of the water that has passed through the filter 36 is reduced while passing through the orifice 38 formed in the nozzle 18f of the spray head 18. [ Water is then injected above the orifice (38). The water jetted from the orifice 38 impinges on the water impact surface 40b of the diffuser 40 and is ejected outside the spray head 18 through the outlet 40a. The water sprayed out of the spray head 18 evenly reaches from the surface of the roof 12 distant from the diffuser 40 to the surface of the roof 12 close to the diffuser 40. The water reaching the roof 12 absorbs the heat of the roof 12 and evaporates. Then, the temperature of the roof 12 is lowered and the inside of the building 14 is cooled.
