The water nozzle 8 may be installed only at the rear or only at the front. It may also be provided on the side. In addition, the number of water spray nozzles 8 can be adjusted to the optimum number according to the application. Just do it. Note that the reference numeral 4 in FIG. 1 indicates a vent provided at the top of each storage chamber 5. It is.

[0009] FIG. 2 is a piping diagram of the water sprinkler truck according to the present invention.

0010 In FIG. 2, reference numeral 10 indicates a bottom valve provided at the bottom of each storage chamber 5. bottom The valve 10 is linked to a handle 11 provided at the upper part of the storage chamber 5. The bottom valve 10 is configured to be openable and closable by rotating the lever 11.

[0011] Each bottom valve 10 is connected to the suction side of the pump P by a pipe 12. This piping 1 2 is equipped with a three-way switching cock 13, and the three-way switching cock 13 is connected to the pump P. The position where the suction side of the valve communicates with the bottom valve 10 and the position where the liquid It is configured so that it can be freely switched to a position communicating with a water supply port 15 to which a source (not shown) is connected. ing.

0012 The discharge side of the pump P is connected to the front and rear water nozzles through a water sprinkling valve 17 by a water sprinkling pipe 16. A circulation valve is connected to a circulation pipe 18 which is connected to a water supply pipe 8 and branched from a water sprinkler pipe 16. It communicates with each storage chamber 5 via 20. The end of the circulation pipe 18 on the storage chamber 5 side is , is disposed at the bottom of the storage chamber 5, and a plurality of jets are installed at this end to inject to the bottom. An ejection port is formed.

[0013] Note that the reference numeral 21 in FIG. 2 is provided in the circulation pipe 18 together with the circulation valve 20. This is a manual on-off valve. Further, reference numeral 22 indicates a discharge pipe branched from the water sprinkler pipe 16. 23 through a discharge valve 24.

[0014] Next, using the water sprinkler 1 configured in this way, first, each storage chamber 5 of the tank 3 is A case will be explained in which the liquid is supplied at the same time.

[0015] A liquid supply source is connected to the water supply port 15, and the on-off valve 7 of the communication pipe 6 is opened to store the liquid. The chambers 5 are communicated via the communication pipe 6, and the three-way switching cock 13 is connected to the water supply port 15 and the pump. Switch the bottom valve 10, water sprinkler valve 17, and discharge valve 24 to the position where they communicate with the suction side of P. The circulation valve 20 and the on-off valve 21 are respectively closed and opened. After this, operate pump P. By doing so, the liquid is pumped from the liquid supply source through the pump P, each circulation pipe 18, and each storage chamber 5. supply to. When supplying this liquid, piping resistance or difference in capacity of each storage chamber 5, etc. If a difference in water level occurs between the storage chambers 5 due to the The water level in the smaller storage chamber 5 is higher than in the other storage chambers 5, and reaches the maximum storage water level first. will be reached. In this way, the storage chamber 5 with low piping resistance and the storage chamber with small capacity The liquid that has reached the maximum storage level at step 5 is discharged to the adjacent storage chamber 5 through the communication pipe 6. As a result, the water level is balanced until each storage chamber 5 reaches its maximum storage water level. You can take

[0016] The liquid supplied to the storage chamber 5 in this way is used, for example, to prevent freezing on the road. In the case of water trucks that sprinkle water, aqueous solutions such as salt or calcium chloride are used. When stored in the storage chamber 5 for a long time, these salts and calcium chloride are deposited at the bottom of the storage chamber 5. This precipitate needs to be stirred because it precipitates.

[0017] In this way, when stirring the precipitate deposited at the bottom of each storage chamber 5 at the same time, as described above, Similarly, the on-off valve 7 of the communication pipe 6 was opened to establish communication between the storage chambers 5 via the communication pipe 6. In this state, move the three-way switching cock 13 to a position where the bottom valve 10 and the suction side of the pump P communicate with each other. switch, open the bottom valve 10, circulation valve 20, and on/off valve 21, and open the water sprinkler valve 17 and drain valve. Close the outlet valves 24 respectively. After that, by operating the pump P, each storage chamber 5 is The liquid is circulated again through the pump P and each circulation pipe 18 to each storage chamber 5, and each circulation pipe 1 By injecting the liquid from the injection port 8, the sediment deposited at the bottom of each storage chamber 5 is stirred. Let it stir.

[0018] During agitation of this liquid, piping resistance or each storage area is Differences in water level occur between each storage chamber 5 due to differences in capacity of the chambers 5, etc., resulting in a storage chamber with low piping resistance. 5 and the storage chamber 5 with a smaller capacity have a higher water level than the other storage chambers 5. but, The liquid in the storage chamber 5 that has reached the maximum storage water level first passes through the communication pipe 6 to the adjacent storage chamber 5. As a result, water is discharged until each storage chamber 5 reaches its maximum storage water level. You can balance the position.

[0019] In addition, when supplying liquid to only one storage chamber 5, or stirring only one storage chamber 5, When performing this, close the on-off valve 7 of the communication pipe 6, and supply and stir the liquid. Close the on-off valve 21 of the circulation pipe 18 that communicates with the storage chamber 5 and perform the same procedure as described above. Good.

[0020] Next, we briefly describe the case of sprinkling or discharging the liquid in each storage chamber 5. Ku.

[0021] First, when sprinkling the liquid in each storage chamber 5, the bottom valve 1 of the storage chamber 5 that sprinkles the liquid 0 is opened, and the three-way switching cock 13 is connected to the bottom valve 10 and the suction side of the pump P. switch to the position, open the water sprinkler valve 17, and open the circulation valve 20 (or on-off valve 21). The discharge valves 24 are respectively closed. After this, by operating the pump P, the storage chamber 5 is Then, the liquid is sprayed from the water spray nozzle 8 through the pump P and each water spray pipe 16.

[0022] In addition, when discharging the liquid in each storage chamber 5, the bottom valve 1 of the storage chamber 5 for discharging the liquid 0 is opened, and the three-way switching cock 13 is connected to the bottom valve 10 and the suction side of the pump P. switch to the position, open the discharge valve 24, and open the circulation valve 20 (or on-off valve 21). The water sprinkler valves 17 are each closed. After that, by operating the pump P, each storage chamber 5 The liquid is discharged from the discharge port 22 through the pump P and the discharge pipe 23.

[Effect of the idea]

As described above, according to the water sprinkler of the present invention, liquid can be simultaneously filled in two or more storage chambers. When supplying water, or when circulating liquid in two or more storage chambers at the same time. However, due to piping resistance or differences in the capacity of each storage chamber, differences in water level occur between each storage chamber. The water level in storage chambers with low piping resistance and storage chambers with small capacity is higher than in other storage chambers. Even if a phenomenon occurs, when the maximum storage water level for which the communication pipe is installed is reached, the communication pipe is removed. The water level in each storage chamber is balanced by discharging liquid into adjacent storage chambers through the Therefore, it can be installed in the upper part of a storage chamber with low piping resistance or a storage chamber with small capacity. Prevents liquid from leaking through the formed vents and distributes the liquid uniformly in each storage chamber. can be stored in
