Description

  The present invention relates to a fire extinguishing apparatus that is particularly suitable for fire fighting activities such as during an earthquake disaster, and more particularly to a simple water pump that pumps water for fire prevention from a water intake of a fire prevention water tank.

  For example, in the event of a major earthquake, fires will occur simultaneously at many locations and buildings will collapse on the road, making it impossible for vehicles to pass through. Therefore, as in the case of the Great Hanshin-Awaji Earthquake that occurred in 1995, in the event of a fire in the vicinity, a rope or the like was pulled up from the intake of a fire prevention water tank such as a road to a bucket as a voluntary disaster prevention. The fire will be extinguished by tying up water. However, the following problems were discovered during disaster drills when pumping water from the intake of the fire prevention tank. That is, when a fire is taken out from the intake port of the fire prevention water tank to the pumping container using a bucket and water is taken out and the bucket relay extinguishes the fire with a bucket relay, there is usually a few meters to the surface of the fire prevention water. The problem of seeing and finding the fear that the pumping operator is frightened and hindering the water intake work is discovered, and the danger that the worker actually falls from the water intake port cannot be denied. In addition, it becomes a factor which delays fire extinguishing work that the work of drawing out the water for fire prevention becomes excessively cautious from such danger and fear.

  Furthermore, when using a pumping container such as a bucket, there is a problem that it is difficult to pump a sufficient amount of fireproof water because the pumping container tends to float on the fireproof water, especially during firefighting activities. After the container reaches the surface of the water, it is required that the opening is submerged in water as soon as possible and a sufficient amount of fire-proof water is drawn up.

As for the device that removes the danger and fear of taking fire prevention water from a water intake of a fire prevention water tank using a bucket or the like as in the present invention, no prior art was found, but for fishing etc. For example, there are inventions described in Patent Document 1 and Patent Document 2 as an invention that allows the bucket to easily tilt and pump water when the water is pumped up with a bucket.

On the other hand, as described above, the pulley mounting rod 30 is slidably fitted into the center of the rear portion of the closing substrate 2 with play.

  Further, the pulley support 3 will be described in detail. A connecting ring 35 is provided at the lower end of the auxiliary rod 31 so as to be freely pivotably connected to the closing substrate 2, which is connected to the divided substrate 20. It is connected to the support ring 26 provided in the. Further, the pulley mounting rod 30 is slidably inserted with a play between the guide plate 23 and the sliding guide 24 at the rear of the central coupling body 21 of the closing substrate 2. A stopper stopper 34 is provided at the lower end of the pulley mounting rod 30 to prevent the pulley guide rod 30 from coming off from the sliding guide 24. The pulley 4 is attached to the upper part of the pulley attachment rod 30 via an attachment arm 32, and a pulling rope 6 is attached to the attachment arm 32 in the vicinity of the pulley 4 as shown in FIG. In order not to come off from 4, a pull-off detent 33 is provided.

  Next, the drawing container 5 will be described. A general bucket having an arc-shaped handle 51 whose both ends are rotatably connected on the diagonal line of the upper edge of the container body 50 is applied. A weight 52 is provided near the center of the handle 51. ing. Further, as shown in FIG. 4, on the side of the container main body 50, a lifting rope 6 for holding the pumping container 5, the closed substrate 2, and the pulley support 3 together using the lifting rope 6. A latch hook 53 for stopping is provided.

  One end of the lifting line 6 is connected to the center of the handle 51 of the pumping container 5, and the entire lifting line 6 does not come out and fall into the fire prevention water tank T at the other end of the lifting line 6. A round bar-like stopper 6a is provided. The stopper 6a can also be used as a handle when pumping up the fire prevention water W.

  In addition, the member shown with the code | symbol 7 is a cover holder, and is an accessory at the time of removing or installing the obstruction | occlusion lid | cover T1 of the water intake T3 of the fire prevention water tank T. FIG. The lid holder 7 includes a handle 71, a rod 72, and a retaining piece 73 attached to the tip of the rod.

The simple water pump of this invention is comprised as mentioned above as an example, and this usage aspect is demonstrated below.
(I) Assembly and installation First, the assembly and installation of the simple water pump 1 will be described. A pulley support 3 and a closed substrate 2 as shown in FIG. The operation of unfolding, assembling and installing from the time of folding and storing integrally bound by 6 will be described.

  First, from the folded and retracted state shown in FIG. 5A, the tied up lifting rope 6 is unwound, and the lifting rope 6 hung between the latch hook 53 on the side of the pumping container 5 and the pulley mounting rod 30. Is removed (see FIG. 5B). Next, the pulley support 3 and the closing substrate 2 are taken out from the pumping container 5, and the sliding guide 24 is slid to the lower end side of the pulley mounting rod 30 while the closing substrate 2 folded in half is expanded. (See FIGS. 5C and 5D). When the sliding guide 24 comes into contact with the stopper stopper 34 of the pulley mounting rod 30, the downward sliding of the closing substrate 2 is stopped, and at this time, the closing substrate 2 is in a state of expanding into a flat plate shape ( (Refer FIG.5 (e)). The closing substrate 2 is not bent in a valley shape due to the structure of the hinge 21 a and the rotation stopper 22. As described above, the simple water pump 1 can be easily assembled.

  On the other hand, the closing lid T1 of the water intake T3 of the fire prevention water tank T is removed by the lid holder 7 as an accessory. Specifically, the latching piece 73 of the lid holder 7 is inserted through the latching hole T2 of the closure lid T1 of the water outlet T3, and the lid holder 7 is rotated by about 90 ° to remove the latching piece 73 from the closure lid T1. It is hung on the back surface of the paper and lifted in that state (see FIGS. 6A and 6B). When the closing lid T1 is lifted, the closing lid T1 is moved by several persons as needed, and then the assembled simple water pump 1 is removed from the peripheral frame T4 of the water inlet T3 as shown in FIG. 6C. Install in. In addition, it is preferable to install the simple water pump 1 at this time with the front surface to which the pulley 4 is attached facing in a direction in which there are no obstacles, for example, in the case of a water intake T3 installed on a road. , Install in the direction of travel or retreat of the road, not in the width direction of the road. The removed closing lid T1 is placed on the placement mark 27 of the closing substrate 2. As a result, the spacer 25 of the closing substrate 2 abuts against the back surface of the closing lid T1 to prevent the closing substrate 2 from being lifted up during the drawing operation.

(Ii) At the time of use of pumping Next, the work of pumping fire prevention water W by the simple water pump 1 assembled as described above and installed at the water intake T3 will be described. The pumping container 5 is dropped from the pumping container passage port 2a of the closed substrate 2 and reaches the water surface (see FIG. 7A). When the pumping container 5 that has reached the water surface reaches the water surface, the handle 51 falls down (see FIG. 7B). At this time, since the weight 52 is attached to the handle 51, the weight 52 vigorously abuts the opening peripheral edge of the pumping container 5 as shown in FIGS. The upper opening is directed into the water and the pumping container 5 sinks a little so as to be pulled by the weight 52. Next, as shown in FIGS. 8 (a) and 8 (b), holding the stopper 6a at the end of the pulling rope 6 and running in the forward direction of the simple water pump 1, the pumping container 5 is raised. When the pumping container 5 rises above the water inlet T3, the pumping container 5 is stopped from rising, and the fire-preventing water W pumped into the transport bucket B is transferred (see FIGS. 9A and 9B). The transport bucket B into which the fire prevention water W has been transferred is transported to the fire site by bucket relays of a plurality of fire fighters, and the fire protection water W is applied to the fire site to extinguish the fire. On the other hand, the pumping container 5 in which the fire-preventing water W has been transferred to the transport bucket B is dropped again into the fire-proof water tank T by, for example, running to the simple water pump 1 with the pulling rope 6 (FIG. 10 (c) )reference). Then, the fire-preventing water W that has been pumped out is successively transferred to a transport bucket B that has been prepared, and fire extinguishing activities are performed by the bucket relay.

(Iii) During storage In order to terminate the fire extinguishing activity and store the simple water pump 1, the reverse procedure of assembly and installation of (i) is followed (see FIGS. 5 and 6). Move the closing lid T1 of the intake T3 placed at the place of the installation mark 27, remove the simple water pump 1 from the intake T3, install the closing lid T1 at the intake T3, and close the intake T3. To do.

Next, the simple water pump 1 is folded and stored, and the sliding guide 24 of the closing substrate 2 is slid above the pulley mounting rod 30 while the closing substrate 2 is folded in a mountain fold at the central connecting body 21. Go. In a state in which the closing substrate 2 is completely folded, both the closing substrate 2 and the pulley support 3 are folded into a compact state. The folded closing substrate 2 and the pulley support 3 are shown in FIG. As shown in FIG. 5 (a), it is put in the pumping container 5, and the lifting rope 6 is hooked several times between the latch hook 53 on the side of the pumping container 5 and the pulley mounting rod 30, and the end is hooked. Tie up and tie up the lifting cord 6. Further, the lid holder 7 of the auxiliary tool is accommodated in the pumping container 5, and the transport bucket B is stored on the top of the pulley mounting rod 30 or stacked below the pumping container 5.
In the state where the simple water pump 1 is folded and stored as described above, it is very compact and does not take up space for storage.

  Moreover, what is shown to Fig.11 (a) (b) is provided with the pulley mounting position adjustment mechanism in the water pumping-up device of this invention. As a specific pulley attachment position adjusting mechanism, various structures can be applied. In the structure shown in FIG. 11A, a sleeve 36 with a fixing knob 36a is provided at the base end portion of the attachment arm 32. It is provided and locked to the pulley mounting rod 30 of the cylindrical pipe so as to be slidable up and down and necked down. Further, the mounting arm 32 is made to be extendable by inserting a metal plate 38 into the square pipe 37 so that it can be fixed by a fixing knob 37a with an appropriate length. Although not shown in the drawings, a holding port that penetrates the pulley mounting rod 30 is provided, and a mounting arm such as a round pipe is slidably inserted into the mounting arm so that the mounting arm is slidably supported, and depending on the position. The position of the pulley may be changed by allowing the position to be fixed with the fixing knob.

Also, in FIG. 11 (b), the mounting arm 32 is composed of two metal plates 38 that are pivotably connected by bolts 39A, and is configured to be able to descend in the vertical direction, with respect to the bolts 39A. The wing nut 39B that is screwed can be fixed at a desired angle.
As described above, when the pulley mounting position adjusting mechanism is provided in the water pump, it is possible to finely adjust the pumping container 5 to a desired position when, for example, the slope is used.

Moreover, what is shown to Fig.12 (a)-(d) enables it to increase / decrease the pumping capacity of the water W for fire prevention by the pumping container 5 according to the physical strength etc. of a pumping operator.
Specifically, what is shown in FIG. 12 (a) is provided with a drain port 54 above the side of the container body 50 and an open / close plate 55 slidable in the vertical direction. A member denoted by reference numeral 56 is a fixing screw for fixing the opening / closing plate 55 at an appropriate open position. When the pumping container 5 is configured as described above, the water intake amount of the container body 50 can be adjusted by the open state of the opening / closing plate 55. For example, when a woman or an elderly person performs the pumping operation, the opening / closing plate 55 is provided. It is possible to reduce the amount of water intake by sliding down the desired amount to reduce the weight. In addition, when adopting such an increase / decrease structure of the water intake amount, a deeply-storing deeply-storing container 5 is applied, and when several people or a person with physical strength draws, the drain port 54 is provided. When it is used as it is without opening it, and it is used by a person who is not, it is possible to reduce the volume by opening the drain port 54 and perform the pumping.

12 (b) and 12 (c) are also provided with an increase / decrease structure of the pumping capacity, which can adjust the tilting posture of the container body 50 in a state where the pumping container 5 is suspended by the pulling rope 6. The configuration is adopted, and the pumping amount of the fire prevention water W in the pumping container 5 is adjusted by this. Specifically, one end of the inclination adjusting string 57 is tied to the handle 51, the other end is passed through one hole 58a of the length adjusting tool 58 having two holes 58a, 58b, and then the upper edge of the container body 50 is attached. Is inserted through the through hole 50a. Further, the inserted end is folded back and inserted into the other hole 58b of the length adjuster 58, and then a knot is formed and locked.
The structure for increasing / decreasing the water intake capacity is as described above. In using this structure, the length of the string between the handle 51 and the through hole 50a of the container body 50 is adjusted by moving the position of the length adjuster 58. Thus, the tilt posture of the container body 50 can be adjusted (see FIG. 12C). Incidentally, as the length of the string between the handle 51 and the through hole 50a is shorter, the inclination becomes larger and the water intake amount decreases.

  Further, in a simple structure, for example, as shown in FIG. 12 (d), the pumping capacity increase / decrease structure is formed low so as to cut out a part of the upper opening edge of the container main body 50. It is possible to shake the container body 50 by actively pulling it back and returning it, spilling a large amount of fire water W, reducing the pumping capacity, and reducing the weight of the pumping container 5 when pumping up. .
