  The present invention relates to an apparatus for removing foreign matter in a fireproof water container for removing and removing foreign matter in a fireproof water tank, a method for removing foreign matter, and a foreign matter removal system, particularly from a fireproof water collection port etc. The present invention relates to a foreign matter removal device, a foreign matter removal method, and a foreign matter removal system suitable for removing foreign matter accumulated in the water pit or the like and foreign matter floating in the fireproof water vessel.

  Conventionally, fire hydrants connected to water pipes and fire protection water pipes exist as fire fighting water users. And since it is essential that these firefighting water functions normally at the time of a fire etc., it is desirable to maintain it regularly.

  Then, in patent document 1 (Unexamined-Japanese-Patent No. 7-286339), the turbid water drainage device for fire hydrants which connected to the existing fire hydrant and was used at the time of cleaning drainage in a distribution pipe and enabled it to collect foreign substances in turbid water to drain was proposed. It is done. Specifically, when cleaning the inside of the water distribution pipe by drainage from the fire hydrant, it is easy to collect foreign objects discharged out of the pipe and to prevent the hose from dancing due to strong drainage momentum. An intermediate joint pipe having a flow meter and a water inlet, a hose having a larger diameter than the fire hose, a strainer and a foreign matter collecting cup detachably attached to an end of the strainer, The turbid water drainage device for fire hydrants formed by connecting the strainer part which consists of a transparent pipe which accommodates these inside in order in this order is proposed.

  On the other hand, fire protection water vessels are often installed in parks and grounds, and the cap on the suction pipe connection side of the water collection ports of the fire protection water vessels is generally not locked. There may be things that have been put.

  Then, there is a foreign matter such as gravel which falls into the water from a lid or a gap of a manhole at a suction pipe inlet and is deposited in a water collection pit at the bottom. Also, there are cases where water absorption from the water collection port can not be performed due to the deposition of the foreign matter, and there are fire protection water pipes which may damage the fire service pump due to gravel mixing in water absorption from the water collection port at the time of fire fighting. For this reason, in the case of fire protection water clogged up by the gravel etc. which the water intake and the water pipe accumulated, it can not be used as fire fighting water and it will lose the function as fire fighting water use.

  Therefore, in the past, in order to check such fire protection water, it is necessary to remove the water in the fire protection water once, enter the water reservoir, and remove foreign matter such as sediment that has been deposited by workers. It was time consuming.

  Hereinafter, with reference to the drawings, a device 40 for removing foreign matter from fire protection water, a method for removing foreign matter, and a system 60 for removing foreign matter according to the present embodiment will be specifically described.

  FIG. 1 is an overall configuration diagram showing a foreign matter removal system 60 for a fire protection water container 80 according to a first embodiment. As shown in this figure, in the present embodiment, the foreign matter removal system 60 is configured by using the pump 50 of the fire engine and connecting the foreign matter removal tool 40 of the fire protection water to this to constitute a foreign matter removal system 60. It is constituted so that the foreign substance removal method concerned can be carried out. However, as shown in a second embodiment to be described later, the pump 50 of the fire engine can also be configured using a pump 50 other than the fire engine (for example, the power pump 50a).

  As shown in FIG. 1, a fire collection pit 80 generally has a water collection pit 83 located immediately below a manhole which is a suction inlet port 82 (or an inspection and cleaning port). For this reason, foreign matter such as gravel which has fallen from the suction pipe inlet 82 is accumulated in the water collection pit 83 and its periphery. The tip of the pipe (hereinafter referred to as a water conduit 84) leading from the water collection port 81 to the bottom of the fire protection water reservoir 80 is generally located in the water collection pit 83 and is absorbed by the water collection pit 83 during fire brigade activity Therefore, the dropped foreign matter is in a state of being easily sucked by the pump 50. If a fire engine absorbs water from the water intake 81, if foreign matter such as gravel enters the pump 50 when mixed with water, the pump 50 may be damaged, damaged, or degraded in performance, causing troubles in fire extinguishing activities. In the worst case, in addition to being inoperable, in the event of a failure, repairs will interfere with the operation of the fire-fighting vehicle. And since the inside of the fire protection water tank 80 is usually filled with water, it is difficult to accurately grasp how much foreign matter is inside.

  Therefore, in the present embodiment, as shown in the general configuration diagram of the foreign matter removal device 40 for fire protection water in FIG. I will provide a. The foreign matter removing device 40 for fire protection water is a suction hose 10 provided at one end with a fitting 11 connected to the water intake port 81 of the fire protection water reservoir 80 and a filtration connected to the other end of the suction hose 10 The separation device 20 and the pump-side water absorption pipe 30 connected to the filtration / separation device 20 are formed. For example, as shown in FIG. 1, the foreign matter accumulated in the fireproof water tank 80 is sucked up by the pump 50 of the fire engine using the foreign matter removal tool 40 of the fireproof water tank so that the foreign matter in the suctioned water is filtered. -Since separation is performed by the separation device 20, it is possible to eliminate the problems such as failure, damage, performance deterioration of the pump 50, and to suck and remove foreign matter in the fire water case or the like.

  The suction hose 10 can be used without particular limitation as long as it can withstand a certain pressure, but desirably, a transparent (including translucent) suction hose 10 is used. This is because it is possible to visually confirm whether foreign matter is mixed in the water (sucking up water) flowing in the suction hose when sucking up the foreign matter floating or accumulated in the fire protection tank.

  As the above-mentioned filtration and separation device 20, various equipment provided for filtration and separation can be used. For example, in addition to a strainer, a Laval separator (sand separator) can also be used. Further, the filtration / separation device 20 can be provided with an inspection port 21 for confirming whether or not foreign matter such as earth and sand has been sucked up. The inspection port 21 is preferably formed as a transparent window so that the inside of the strainer can be visually confirmed. In the present embodiment, as shown in FIG. 3, the inspection port 21 is provided on the upper surface side, but it is naturally possible to form this on the side surface. When the strainer is a Y-type strainer, it is desirable to provide a stand 22 for fixing and holding the direction. For example, as shown in FIG. 3, it is desirable that the stand 22 be configured such that the filtration chamber 23 (the dust collection chamber) in the Y-type strainer faces downward. Furthermore, since the strainer has water flow directionality to remove foreign matter, it is possible to identify the members connected to the strainer inlet 28 and the outlet 29. It is desirable to make the connection structure different. That is, the suction hose 10 is preferably connected to the inlet 28 of the strainer, and the pump-side suction pipe 30 is preferably connected to the outlet 29 of the strainer so that the connection structure is different. In particular, in the case where a split suction pipe is used as the pump-side water absorption pipe 30, since both ends of the split suction pipe are a fitting for fire fighting, a fitting provided on the outlet 29 side of the strainer is a fitting for fire fighting Is desirable.

  In the present embodiment, a Y-type strainer shown in FIG. 3 is used as the filtration / separation device 20. FIG. 3 is a (A) longitudinal sectional view showing a Y-type strainer, and (B) an outflow side view. By using such a Y-type strainer, it is possible to easily remove the sucked foreign matter (such as earth and sand), and since the foreign matter which has flowed in from the water absorption side port can be accumulated in the filtration chamber 23, many foreign matters can be collected. It becomes possible to accept.

  As said pump side water absorption pipe 30, the pipe and hose which are not crushed by negative pressure also at the time of water absorption can be used, for example, a suction hose, a divided suction pipe, a vinyl chloride pipe, or a metal pipe etc. can be used. .

  Further, it is desirable to provide a connector 31 for connecting to the water suction port 51 of the pump 50 also on the tip end side of the pump-side water absorption pipe 30 (that is, the connection end side with the pump 50). In particular, in the present embodiment, since the pump 50 uses the pump 50 of a fire engine, the connector 31 is a plug-in type connection fitting used, preferably a plug-in type connection fitting used for a fire hose It is desirable to use a screw-type fitting (a screw-type socket or a screw-type receptacle) used for a hose for insertion or a plug-in type or a fire hose.

  Further, in the foreign matter removal device 40 configured as described above, the internal pressure of at least one of the suction hose 10, the filtration / separation device 20, and the pump-side water absorption pipe 30 is acquired to obtain the filtration / separation device. It is desirable to have a clog detection device 25 that detects clogs 20. Even if the filtration / separation device 20 is clogged due to the accumulation of foreign matter, this can be known by the clogging detection device 25, so the pump 50 can be stopped to prevent the occurrence of cavitation, and the pump 50 can be safely used. I can drive. It is also desirable that the pump 50 be automatically stopped in response to a clogging detection signal from the clogging detection device 25.

  The clogging detection device 25 can be provided in the filtration / separation device 20, as shown in FIG. 3, for example. In the Y-type strainer shown in FIG. 3, branch paths 24 are respectively provided on the upstream side and the downstream side of separation members 23 a such as filters or meshes provided in the filtration / separation device 20, with respect to the branch paths 24. It is comprised so that filtration / separation apparatus 20 can be provided detachably. The pressure difference between the upstream side and the downstream side of the separation member 23a can be detected by the filtration / separation device 20 to detect the presence or absence of clogging. Further, the clogging detection device 25 measures a differential pressure and the like before and after the filtration / separation device 20, and a differential pressure gauge with a contact that outputs a clogging detection signal when the differential pressure exceeds a specified value, or filtration / separation. Between the device 20 and the suction port of the pump 50, a pressure gauge with a contact (not shown) may be configured to output a clogging detection signal when it is detected that the suction pressure has dropped abnormally. It is desirable that such a differential pressure gauge with a contact point be provided with notification means for notifying clogging by an alarm, light emission, etc. For example, a multi-functional digital differential pressure gauge (Model GC50) manufactured by Nagano Keiki Co., Ltd. can be used.

  The clogging detection device 25 can also measure the internal pressure of at least one of the suction hose 10, the filtration / separation device 20, and the pump-side water absorption pipe 30, and detect the clogging by the pressure. For example, the internal pressure of at least one of the suction hose 10, the filtration / separation device 20, and the pump-side water absorption pipe 30 may be measured with a vacuum gauge or the like to judge (detect) the presence or absence of clogging based on a certain value. it can. Further, the clogging detection device 25 can use a flow meter (not shown) for measuring the flow rate inside at least one of the suction hose 10, the filtration / separation device 20, and the pump-side water absorption pipe 30. . In this case, when the flow rate becomes equal to or less than a certain reference value, it can be detected as being clogged.

  The clogging detection device 25 can be provided in at least one of the suction hose 10, the filtration / separation device 20, and the pump-side water absorption pipe 30, but is desirably provided in the filtration / separation device 20. By providing the filter in the filtration / separation device 20, the handling and handling can be facilitated.

  Using the fire protection water removal device 40 configured as above connected to the pump 50 (hereinafter referred to as "firefighting pump 50") of a fire engine (firefighting pump car or portable firefighting pump 50) In firefighting pump 50, we perform pumping, discharge equivalent to firefighting activity of firefighting pump 50 by firefighting pump 50 mainly in firefighting activities other than patrol check of firefighting staff, members of firefighting team mainly and firefighting water pump 50 Reflux) can be checked and cleaned.

  Pumping water is equivalent to that at the time of an actual fire (about 1,000 L / min), and by circulating the water inside the fire protection water tank 80, mixing of foreign matter in the water stream near the time of fire fighting in the fire protection water tank 80 As a result, it is possible to separate, remove and clean foreign matter and the like that may be an obstacle to the fire extinguishing activity in the fire protection water box 80 centering on the water collection port 81 and the water conduit 84 and the water collection pit 83.

  That is, when the foreign matter such as gravel deposited in the water collection pit 83 absorbs water from the water collection port 81, the fire and the fire are drawn by suction from the water absorption port 51 which is the tip of the water pipe 84 located in the water collection pit 83. It is sucked to the pump side. The foreign matter removal system 60 of the fire protection water vessel 80 according to the present embodiment prevents foreign matter from flowing into the pump 50 and the pump piping and the fire suction pipe, and also prevents foreign matter in water in the water conduit and the fire protection water vessel. It can be removed and cleaned. Then, as shown in FIG. 1, a reflux piping can be connected to the water supply side of the pump 50, and the reflux piping can be introduced into the fire protection tank from the inspection and cleaning port (suction pipe inlet 82) or the like. Thereby, the water from which the foreign matter has been removed by the foreign matter removal system 60 according to the present embodiment can be returned to the inside of the fire protection tank.

  And, by using the foreign matter removal system 60 of the fire protection water container 80 according to the present embodiment and periodically checking the fire protection water container 80, the fire pump 50 can not be damaged or pumped up during the fire fighting activity. You can prevent such troubles in advance.

  Furthermore, according to the foreign matter removal system 60 of the fire protection water container 80 according to the present embodiment, the foreign matter is removed by the filtration / separation device 20, so the presence or absence of the foreign matter can not be visually recognized or the internal condition is unknown. Even with the fire protection water tank 80, inspection and cleaning work can be performed without risk of damage to the pump 50.

  And, according to the foreign matter removal system 60 of the fire protection water container 80 according to the present embodiment, since the work can be performed in a short time without risk of pump damage, each jurisdiction and responsible district in the patrol inspection of the fire brigade staff It is possible to carry out periodical water pumping and inspections sequentially in a plurality of fire protection containers 80 such as.

  When using the pump 50 of a firefighting pump automobile as the pump 50 used in the foreign matter removal system 60 of the fire protection water container 80 according to the present embodiment and performing inspection, the difference is not in the water intake port 51 but in the relay port. Since it is possible to connect by means of a plug-in bracket, it is not necessary to remove or use the fire protection pipe mounted on the vehicle.

  And, by making the connector on the pump connection side plug-in type, connection / disconnection work can be performed in a short time. Therefore, even when the need for dispatching occurs at the time of cleaning work, foreign matter removal according to the present embodiment is carried out. Since it is possible to remove the device 40 from the pump 50 of the fire engine and leave the device 40 in a safe place near the work place, it is possible to prevent a delay in the initial movement.

  Furthermore, the foreign matter removal device 40 for fire protection water according to the present embodiment is removable for connection between the suction hose 10 and the filtration / separation device 20 and for connection between the filtration / separation device 20 and the pump-side water absorption pipe 30. It is possible to mutually divide by configuring in. As a result, the filtration / separation device 20 can be easily loaded on a fire engine having a small amount of empty space of the vehicle, and the operation in the patrol inspection on the fire vehicle can be facilitated.

  In particular, in order to be able to be divided and loaded on a fire engine in the foreign matter removal tool 40 for the fire protection water, when the split suction pipe is loaded on a vehicle loaded on the upper part of the vehicle, the suction hose It is desirable that the length of the 10 and the pump-side suction pipe 30 be 2.5 meters or 3.3 meters, and that the divided suction pipes can be changed and loaded. As it is possible to work with the equipment and materials that are usually loaded, disaster response will not be disturbed.

  And, by using the fire protection water removal device 40 according to the present embodiment, it is possible to work at the time of patrol check by the fire pump 50 used by the fire department staff, so outsourcing There is no need for labor and expenses.

  And since foreign matter removal tool 40 of fire protection water concerning this embodiment is a suction pipe for inspection to the last, it is a premise of not using it in a real disaster, and the examination duty of the examination system of firefighting equipment of component equipment is It is also possible to reduce the manufacturing cost without being applied.

  Furthermore, in the case where a transparent suction hose 10 is used as the suction hose 10, it is expected that this will lead to the improvement of the pump operation technology of the engine personnel, since the pumped water state inside the suction pipe is visible.

  And the foreign material removal system 60 of the fire protection water container 80 which concerns on this Embodiment does not have consumption of the firefighting water by operation | work, and inspection of several places and cleaning work are possible in a short time. In addition, since firefighting water inside fire protection water tank 80 is not consumed by work, unusable time as fire water service does not occur.

  FIG. 4 is an entire configuration view showing a foreign matter removal system 60a of a fire water reservoir 80 according to a second embodiment. The foreign matter removal system 60a according to this embodiment is configured using a power pump 50a or the like as a pump other than a fire engine. Also in this embodiment, the foreign matter removing device 40 shown in FIG. 1 is used. That is, a foreign matter removal device 40 for fire protection water is connected to the water absorption side of the power pump 50 a, and this is connected to the water collection port 81 of the fire protection water case 80. Then, foreign matter such as gravel is removed from the water absorbed by the filtration / separation device 20. And the water which removed gravel etc. can be recirculated from the inspection cleaning port (suction pipe inlet 82) of fire protection water container 80 etc. via the reflux piping connected to the said water supply side.

  Furthermore, FIG. 5 is a whole block diagram which shows the foreign material removal system 60b of the fire water reservoir 80 which concerns on 3rd Embodiment. In the embodiment shown in this figure, it is configured with an extension pipe 15 which can be inserted from the inspection and cleaning port (the suction pipe inlet port 82) of the fire water reservoir 80. The extension pipe 15 can be used by being connected to the tip end side of the suction hose 10 (that is, the side connected to the water intake port 81 of the fire protection water reservoir 80) in the foreign matter removal device 40 for fire protection water drainage. The extension pipe 15 can use, for example, a vinyl chloride pipe, a metal pipe, or a suction hose, and can use a member that can be directly inserted into the water collection pit 83 from the inspection cleaning port (suction pipe inlet 82). . By using the extension pipe 15, water and foreign matter in the water collection pit 83 and its periphery can be directly suctioned by vacuum suction. In addition, in order to enhance the ease of inserting into the water collection pit 83, a weight may be provided on the lower end side of the extension pipe 15, or the configuration may be such that it is easy to sink. Further, in this embodiment, since the work with the extension piping is preferably performed by a small power pump, the power pump 50a is used, but it is of course possible to use the pump 50 of a fire engine is there.

  From the above, according to the foreign matter removal device 40 for fire protection water, the foreign matter removal method, and the foreign matter removal system 60 according to the present embodiment, the following problems can be solved.

  That is, when performing a water absorption operation by a suction pipe always connected to a fire engine at the time of daily patrol inspection of a fire service staff, when a real disaster etc. occurs during the operation and it becomes necessary to move, time for storage after use It is possible to solve the problem that the response is delayed because it is necessary.

  In addition, when firefighting staff try to do cleaning work using equipment such as submersible pump during work, firefighting pump car has a small loading space other than firefighting equipment parts and equipments and brings down equipments for disaster response It is necessary to take measures such as, and the operation time is also long, so it is possible to solve the problem that it is difficult to carry out at the time of ordinary patrol inspection and the like.

  In addition, if a cleaning company performs a complete set of work after removing water and cleaning up and refilling water, costs of several tens of thousands to hundreds of thousands of yen are required, but the municipalities set up, maintain and manage by the Fire Service Law, There is a considerable number of fire protection water tanks 80 designated by the fire department chief or fire department chief to be in the state of being always usable, so the financial burden of periodically draining and cleaning all is It is possible to solve the problem of having been large.

  Moreover, since the water in a water tank will be lose | eliminated temporarily, the cleaning accompanied by draining can solve the subject that the time which can not be used as a fire water service arises.

  And although a strainer is attached to the water intake port 51 and the relay port in the firefighting pump car, even if it is gravel of a size that passes these eyes, there is a risk of damaging the pump 50 depending on the amount, and a small power Since the fire pump 50 generally does not have the water intake port 51 strainer as a standard, it is possible to solve the problem that foreign matter entering the suction pipe is highly likely to cause the pump 50 to be fatally damaged.

  The apparatus for removing foreign matter, the method for removing foreign matter, and the foreign matter removal system according to the present invention can be used for maintenance of fire water, especially for removal of foreign matter, and further provided in industry, facilities, etc. It can also be used for maintenance of water storage tanks.
