It is the image figure which showed the state arrange | positioned to the building of the water discharge head, and the state of water discharge to the building, (a) is for the whole building, (b) is for only the outer wall part of the building. is there. It is a system block diagram of the fire extinguishing equipment of other embodiment.

  In FIG. 1, the fire extinguishing equipment S includes a water discharge head 1, a simultaneous opening valve 2, an electric valve 3 for controlling the opening and closing of the simultaneous opening valve 2, a fire discharge sensor 4 which is an example of a fire detection means, and a signal control means. An arson suppression control panel 5 is provided as an example, and the primary side of the simultaneous release valve 2 is connected to the water pipe P0 that is a fire-extinguishing water supply source via the primary side pipe P1, and the secondary side of the simultaneous release valve 2 is the secondary side. It is connected to the water discharge head 1 via the pipe P2, and the fire discharge sensor 4 and the electric valve 3 are connected to the fire discharge suppression control panel 5 via the signal lines SD and SM, respectively.

  In the fire extinguishing equipment S, the simultaneous release valve 2 is normally closed, and the primary side and the secondary side are shut off, and the water in the water pipe P0 is not supplied to the water discharge head 1, and the water is discharged. In the event of a fire, if the fire sensor 4 detects a fire in the event of a fire, a fire detection signal is sent to the fire suppression control panel 5, and the fire suppression control panel 5 sends a valve opening signal to the motor-operated valve 3. The simultaneous opening valve 2 is opened by the operation of the feeding and motor-operated valve 3, the primary side and the secondary side communicate with each other, and the water in the water pipe P0 is supplied to the water discharge head 1 to be discharged.

  In the present embodiment, the simultaneous opening valve 2 is opened by the operation of the motor operated valve 3 so that the primary side and the secondary side communicate with each other. For example, as shown in FIG. Instead of the valve 2, an electric valve 3a may be provided between the primary side and the secondary side, and the primary side and the secondary side may be directly communicated with each other by the valve opening operation of the electric valve 3a.

  This fire extinguishing equipment S can be used as a fire prevention target for special buildings such as cultural properties, general buildings such as houses, garbage dumps, etc. be able to.

  As shown in FIG. 3, the water discharge head 1 has a pipe shape, and a plurality of water discharge holes 1 a are formed in the peripheral wall 1 w. This pipe-shaped water discharge head 1 has a simple structure in which a plurality of holes are formed in a pipe-shaped one, and can be manufactured at a lower cost than a complicated structure such as a sprinkler head or a drainer head. Since the water discharge head 1 is provided, the fire extinguishing equipment S can reduce the equipment cost.

  Further, as will be described in detail later with reference to FIG. 5, when water is discharged toward a wall surface such as the outer wall W, the fire water discharged from the water discharge head 1 forms a substantially parabola due to its own weight. When it collides with W, it spreads in the lateral direction along the outer wall W due to the collision, and flows down in the vertical direction along the outer wall W due to the dead weight of the fire extinguishing water, so that the outer wall W is totally wetted. The diameter of the water discharge holes 1a and the distance between the holes can be determined by the distance, the water discharge pressure, and the like, and the water discharge amount can be reduced by determining the hole diameter and the distance between the holes so as to reduce the water discharge unevenness.

  Regarding the arrangement and shape of the plurality of water discharge holes 1a of the water discharge head 1, the one shown in FIG. 3 has a plurality of water discharge holes arranged in a line in the axial direction on one side of the circumferential wall 1w. Each shape is round.

  The arrangement and shape of the plurality of water discharge holes 1a of the water discharge head 1 can be changed as appropriate. For example, as shown in FIG. 4 (a), although the plurality of water discharge holes are arranged along the axial direction, An arrangement that does not line up in the direction, specifically, an arrangement in which a plurality of water discharge holes arranged obliquely with respect to the axial direction (also referred to as oblique with respect to the circumferential direction) are arranged at predetermined intervals in the axial direction may be employed. As shown in FIG. 4 (b), a plurality may be arranged along the circumferential direction of the peripheral wall 1w, and a plurality may be arranged along the axial direction (length direction). (C) and (d) As shown in FIG. 4, the shape of the water discharge hole 1a may be an elongated slit shape instead of a round shape, and a plurality of the water discharge holes 1a are arranged in the circumferential direction and the axial direction while extending along the circumferential direction (c ) Or extending obliquely with respect to the axial direction (also referred to as oblique with respect to the circumferential direction) It may be or a plurality lined arranged at predetermined intervals in a direction (d).

  And although details are described later, the water discharge head 1 extends along the fire prevention target, and a plurality of water discharge holes 1a can discharge water toward the fire prevention target. With fire water from 1a, the fire water collides with the fire protection object due to its own weight, collides with the fire protection object, and flows down along the fire protection object while spreading, so that the fire protection object can be wetted as a whole and the fire protection object burns. This makes it difficult to prevent the fire target from burning. In addition, not only what discharges the several water discharge hole 1a of the water discharge head 1 toward a fire prevention object, but what should discharge water toward a fire source, if it does so, not only a fire prevention object, The water can be discharged toward the fire source, and the fire of the fire source can be extinguished or its momentum can be suppressed while preventing the fire prevention target from burning. In this case, for example, if the arrangement of the plurality of water discharge holes 1a is provided not only on one side half of the peripheral wall 1w of the water discharge head 1 but also on the opposite side, not only the fire prevention target but also toward the fire source. Can also be discharged.

  Here, as described above, the fire extinguishing equipment S can be set as a fire prevention object such as a special building such as a cultural property, a general building such as a house, a garbage collection point, etc. The fire extinguishing equipment S is provided with an arson sensor 4 as a fire detection means in correspondence with it. The arson sensor 4 includes a flame sensor and a human body sensor, and can detect a flame and a human body. When the flame sensor senses a flame and the human body sensor senses a human body, By making the fire extinguishing equipment S determine that a fire has occurred due to arson, it is possible to prevent activation by a non-fire.

  In the present embodiment, the arson sensor 4 includes a flame sensor and a human body sensor in one case, but it is a matter of course that both sensors may be divided into separate cases. Depending on the environment of the installation location, both sensors may be provided close to each other or separated from each other. Further, in the present embodiment, the arson sensor 4 is an example of a fire detection means, and instead of the arson sensor 4, the human body sensing function is lost, but a fire detection means without a human body sensor may be used. Of course.

  And when the fire prevention object is a building or the like, the water discharge head 1 can be extended along its outer wall or under the floor and disposed so as to be able to discharge water toward the outer wall or under the floor. Specifically, for example, as shown in FIG. 5A, when the fire prevention target is a building H, the water discharge head 1 is disposed along the outer wall W under the eaves E of the building H. Can be. In FIG. 5A, the water discharge head 1 is represented by a single pipe that matches the width of the building H, but a plurality of short pipes are adjusted to the width of the building H so that there is no uneven discharge in the lateral direction. The pipe length may not be changed for each installation place, and it becomes easy to carry.

  FIG. 5A shows a state when the fire extinguishing equipment S starts to discharge water in response to a fire caused by the arson C. The arson by the arson C can be detected by the flame sensor detecting the flame of the ignition F1 or the fire source F2 and the human body sensor detecting the presence of the arson C, and the fire extinguishing equipment S is discharged by the detection. Will be activated. When the fire extinguishing equipment S starts discharging water, the water discharging head 1 discharges water T from the water discharging hole 1a, but as shown in FIGS. 5 (a) and 5 (b), toward the outer wall W of the building H, Since the water discharge head 1 discharges the fire-extinguishing water T, the fire-extinguishing water collides with the outer wall W by making a substantially parabola by its own weight, and flows down along the outer wall W while spreading, so that the outer wall W can be wetted as a whole. The fire extinguishing equipment S can prevent the outer wall W and, in turn, the building H from burning. In addition, if the water discharge hole 1a includes what discharges water toward the fire source F2, the fire of the fire source F2 can be extinguished or its momentum can be suppressed. If water discharge is started at the stage where there is ignition F1 (for example, the sensitivity of the flame sensor is set high), it is possible to check the fire criminal C and prevent it from being fired.

  Finally, the fire-extinguishing water supply source in the fire-extinguishing equipment S will be described. What is shown in FIG. 1 uses water supply as a source of fire water. By using water supply, there is an advantage that the facility cost can be reduced, but the amount of water discharge and the water discharge pressure may be insufficient. Therefore, although the equipment cost becomes high, it is possible to use a water storage tank and a water pump instead of using the water supply. Specifically, for example, as shown in FIG. 6, the fire-extinguishing water supply source may be a water storage tank TA and a water supply pump P, and the primary side pipe P <b> 1 of the simultaneous release valve 2 may be connected thereto. . Thereby, the water discharge amount and the water discharge pressure can be increased, and the fire extinguishing ability can be increased. In addition, SP is a signal line which connects the water pump P and the fire suppression control panel 5 and is for sending an activation signal from the fire suppression control panel 5 to the water pump P at the time of water discharge activation.
