Description

  The present invention facilitates the retention of rainwater and other water in various places indoors and outdoors, especially when rainwater or the like stays on a solid foundation of a building under construction. In addition, the present invention relates to a drainage device capable of draining reliably and making the staying region dry.

  There are a variety of pump devices available on the market, which are suitable for pumping out of ponds, rivers, lakes, wells or tanks, etc. It is not possible to find it appropriate to discharge the water to a suitable place outside it. Furthermore, no device can be found that can dry the area after draining. In addition, after some investigations, it seems that no device has been proposed for a device suitable as a drainage device for the above-mentioned use.

  Patent Document 1 relates to a rainwater drainage pump device, and in a rainwater drainage pump device in which it is difficult to provide a sufficiently large sedimentation basin upstream of the drainage pump, a landing set installed upstream of the drainage pump. A step is provided at the bottom of the well.

  According to this patent document 1, rainwater is introduced into a landing well to reduce the flow velocity, and by depositing earth and sand in the rainwater immediately before the stepped portion formed at the bottom of the drainage well, It is said that accumulation of earth and sand in the water absorption tank on the suction port side can be prevented. Although it seems to be certain that it works, the drainage pump itself seems to be an existing one, for example, at a depth such as the drainage of rainwater that has accumulated on the foundation upper surface of the building under construction. Draining shallow stagnant water appears to be difficult, and it is absolutely impossible to continue to dry the area following drainage.

  Patent Document 2 relates to a drainage pump, and in a drainage pump in which a through hole is formed in a suction casing on an impeller inlet side and an air pipe communicating with the outside is connected to the through hole, water is provided downstream of the impeller. A draining pipe and an open / close valve interposed therein are provided, and the pipe communicates with the upstream side of the impeller so that when the drainage is stopped, the open / close valve is opened to reduce the pressure on the downstream side of the impeller. It is provided with a control mechanism for controlling.

  According to the drainage pump of Patent Document 2, the water level of the water tank is lowered at the time of the previous drainage, and air enters the vicinity of the impeller inlet, and when the water level next rises and the drainage operation is started, the water level remains in that part. If so, the air can be discharged, and the on-off valve is opened to reduce the pressure on the downstream side of the impeller. Therefore, when drainage operation is started from a standby state, it is said that pumping or draining can be performed reliably. And it seems to be certain that this works, but the drainage pump of this Patent Document 2 is a conventional pump device such as a spiral pump or a car flow pump, for example, as described above. Drainage of shallow water, such as drainage of rainwater that has accumulated on the top surface of a building under construction, seems to be difficult, and it is absolutely impossible to continue drying the area after drainage. It is.

  Patent Document 3 relates to a drainage pump. In the drainage pump configured to transmit a rotational output of a prime mover to a main shaft through a compound speed reducer incorporating a speed reducer or a variable speed fluid coupling, Two variable speed fluid couplings are interposed in series in the power transmission system from the output rotating shaft of the prime mover to the main shaft of the drainage pump.

  According to the drainage pump disclosed in Patent Document 3, during normal drainage, the drainage pump is driven at a high speed by the rated operation of the prime mover so that the drainage pump can handle a large amount of rainwater. By cooperating with the low output rotation of the prime mover and the speed change operation of the two variable speed fluid couplings, the drain pump is rotated at a very low speed, and a very small amount of drainage operation is performed, so that it flows into the water intake well from the river. It can respond appropriately to the drainage of the very small amount of rainwater that has come. Therefore, even if the drainage operation is started by the drainage pump at the time of the low rainfall and the extremely low rainfall, the rapid rise and fall of the water level of the water absorption well will not be repeated. In addition, the water level does not drop below the operable water level, and the suction of air from the drainage pump can be avoided. As a result, no significant vibration or noise is generated. According to the drainage pump of this patent document 3, it is recognized that such an effect | action and an effect are acquired.

  However, the drainage pump of Patent Document 3 is also an existing pump body, and the drainage of rainwater staying on the upper surface of the foundation of the building under construction is the same as the rainwater drainage pump device or drainage pump of Patent Documents 1 and 2. It seems that it is difficult to drain stagnant water having a shallow depth like this, and it is still impossible to dry the area after draining.

Japanese Patent Laid-Open No. 06-248690 Japanese Patent Laid-Open No. 06-272689 Japanese Patent Application Laid-Open No. 09-014177

  In the case where rainwater or other water stays in various places indoors or outdoors, the present invention drains all such staying water easily and reliably, and makes the staying area dry if necessary. An object of the present invention is to provide a drainage device that can also be used.

A first aspect of the present invention is a container-like device main body having a closed lower opening and a compressed air introduced into the container-like device main body, each of which is closed by a top plate portion and a peripheral side plate that hangs downward around the periphery. A nozzle part to be ejected from the internal space to the drain port, and a drain port opened to a top plate part or a peripheral side plate on the front end side of the container-like device body, and the air jet spouted from the nozzle part during a draining operation A drainage outlet for draining the drainage target water sucked from between the lower end of the peripheral side plate and the bottom surface of the drainage target part together with the air jet, and the drainage target water and the air jet are guided and drained from the drainage outlet to the outside . A drainage guide pipe having an outer end that is a drainage end and a drainage guide pipe that is configured by a rigid and linear pipe body that extends obliquely upward from the drainage port .

2 of the present invention is the drainage device of 1 of the present invention,
In the lower end of the peripheral side plate of the container-like device main body, a plurality of microprojections for forming a gap for projecting a microgap between the bottom surface of the site to be drained is projected during the drainage operation.

  The drainage apparatus of 1 of this invention connects a compressor to the nozzle part via a hose member etc., and uses it by setting to the waste_water | drain target site | part where the drainage target water is stagnating. The container-like device main body is set in the drainage target portion with the lower opening facing downward and the discharge port at the outer end of the drainage guide tube facing the place where drainage can be received. The target water for drainage is not particularly limited. These are various kinds of unwanted water. For example, it is rain water etc. which stayed on a solid foundation such as a building under construction, and the container-like device main body of this device as described above is disposed in the drainage target portion where the drainage target water such as the staying rainwater stays. When the compressor is operated by lowering the lower opening downward, the compressed air generated by the compressor is pumped to the device through the hose member and the like, introduced into the nozzle portion, and through the nozzle portion. It will be ejected from the internal space to the drain.

  When the air jet flows to the drain outlet side through the nozzle portion as described above, the drainage of the accumulated rainwater or the like through the minute gap between the lower end of the peripheral side plate of the container-like device body and the bottom surface of the drainage target portion. The target water is sucked and introduced together with the jet air to the drain port side. As long as target water such as accumulated rainwater exists around the main body of the container-like device, the suction and the guiding action to the drain outlet side will continue, and all the target drainage water will eventually be drained. Become.

  When the container-like device body is disposed in the drainage target site where the drainage target water stays, there is a minute gap between the lower end of the peripheral side plate and the bottom surface of the drainage target site. That is, since it is almost impossible that the bottom surface of the drainage target portion where the drainage target water stays is completely flat, even if the lower end of the peripheral side plate of the container-like device body has a linear configuration, In most cases, the lower end of the peripheral side plate and the bottom surface of the drainage target part are in contact with each other at some parts, and there are minute gaps therebetween.

  As described above, a minute gap is generated in almost the portion between the lower end of the peripheral side plate of the container-like device main body and the bottom surface of the drainage target part, so that the stagnant water having a very shallow surrounding depth through the minute gap, For example, it becomes possible to draw in the stagnant water having a depth of 1 mm or less or wetness of the bottom surface. The shallow water will be drawn in the form of mist. Since the accumulated water up to the wet level can be sucked and discharged in this way, it is possible not only to drain the accumulated water but also to proceed to the place of drying. In addition, it cannot be overemphasized that not only the shallow stagnant water as mentioned above but the deep stagnant water can be sucked.

The stagnant water drawn into the internal space of the container-like device body passes through the internal space, is further drawn into the drainage port, moves to the outside through the drainage guide pipe, and can accept drainage from the discharge port. It will be discharged to a proper place. The drainage guide pipe is a tubular body that guides the accumulated water drawn into the air jet ejected from the nozzle portion to the discharge port while suppressing the expansion and diffusion thereof. The length is determined in consideration of the amount and speed of the compressed air ejected from the nozzle portion, and should be configured longer if they are larger and shorter if smaller. The drainage guide pipe is configured as a rigid body , and the upward angle is determined in consideration of the height of the barriers to the place where the accumulated water can be received. Of course, there are various cases, so it is appropriate to prepare it at a plurality of angles. Alternatively, the drainage guide pipe is preferably attached to the drain outlet at a variable angle. In this case as well, the amount and speed of the compressed air ejected from the nozzle portion depending on the angle should be considered. It is easy to determine experimentally . The inner surface of its should be smooth.
Note that, as described above, the drainage guide pipe is configured by a rigid and linear tube body extending obliquely upward from the drainage port, so that the sucked accumulated water is guided to the drainage end which is the tip discharge port. and by discharging waste water, for example, even when the drainage target region that is surrounded by some partition, it is possible to guide discharged wastewater to the outside of the discharge destinations beyond its partition.

  If the place where the drainage can be accepted is a drainage groove or an inclined surface with a downward slope connected to the drainage groove, it is sufficient to drain the accumulated water, but the length of the drainage guide pipe, etc. When draining to a place such as a temporary storage place, the drainage can be completed by draining again to the drainage groove or the inclined surface with a downward slope connected to the drainage groove with this drainage device.

  As described above, the nozzle portion is a means for introducing compressed air and ejecting the compressed air from the internal space of the container-like device body to the drain outlet. This means that both the case where the compressed air is ejected toward the outlet and the front side is positioned in front and the case where the outlet is positioned inside the outlet and the compressed air is ejected inside are included. When the nozzle hole is arranged in front of the drain port, most of the accumulated water that is sucked into the air jet jetted from the nozzle hole and moves to the drain port side while gradually expanding together with the air jet flows into the drain port. It is arranged at a position in the range of the distance to the drainage port.

  Further, according to the drainage device of the present invention, foreign matter that passes through the gap between the lower end of the peripheral side plate of the container-like device body and the bottom surface of the drainage target portion and can pass through the drainage guide tube from the drainage port is discharged without any problem. In particular, the gap between the lower end of the peripheral side plate and the bottom surface of the drainage target site can be removed by lifting the container-like device body even if foreign matter is clogged, so there is no problem. For example, when draining rainwater, etc. collected on a solid foundation of a building under construction, various building waste materials may be mixed in, but any material that can pass through the gap below the lower end of the peripheral side plate is discharged without any problem. can do. Further, in the case of drainage of rain water or the like as described above, it may be necessary to drain muddy water, but this can be performed without any problem. In particular, when a large amount of mud is dispersed and the viscosity is high, it can be easily discharged by adding water and lowering the viscosity. Even when mud is accumulated in the drainage target area, it can be easily discharged by adding water to make mud with low viscosity, and it is also possible to clean the mud area . Even if it is a swarf generated by electrical work, it can be discharged in the same way. As described above, drainage target water mixed with foreign matter can be drained, and there is almost no risk of failure due to this.

  According to the drainage device 2 of the present invention, since the plurality of gap-forming microprotrusions are projected at the lower end of the peripheral side plate of the container-like device body, a special case where the drainage target portion is completely flat Even in the drainage operation, it is possible to make a minute gap between the lower end of the peripheral side plate of the container-like device body and the bottom surface of the drainage target part, and the drainage operation is possible in any case. .

  EMBODIMENT OF THE INVENTION Hereinafter, the form for inventing is demonstrated in detail, referring Examples attached based on Examples 1-6.

<Example 1>
As shown in FIGS. 1 (a) to 1 (c) and FIGS. 2 (a) and 2 (b), the drainage device according to the first embodiment includes a container-like device body 1 having a quadrilateral (square) lower opening in plan view, , A nozzle part 3 for jetting compressed air from the internal space of the container-like device body 1 to a drain port 2 located on the tip side thereof, and a drain guide for guiding and discharging the air jet and drain target water from the drain port 2 to the outside It consists of a tube 4.

  As shown in FIGS. 1 (a) to 1 (c) and FIGS. 2 (a) and 2 (b), the container-like device main body 1 has a top plate portion 1a and a peripheral side plate that hangs downward on all four sides. Reference numeral 1b denotes a box-shaped member having a lower opening in which the lower part is closed and the lower part is fully opened. In this embodiment, a plurality of minute protrusions 1 bp, 1 bp,... Are protruded from the lower end of the peripheral side plate 1 b at regular intervals. This is a means for creating a minute gap between the lower end of the peripheral side plate 1b and the bottom surface of the drainage target part during the drainage operation, and is a means for sucking the drainage target water from the outside through this minute space. Since the bottom surface of most drainage target parts is not completely flat and has some irregularities, such a small protrusion 1 bp, 1 bp... Are not arranged on the lower end of the peripheral side plate 1 b. In addition, although a minute gap naturally occurs between the lower end and the bottom surface of the drainage target part, it is configured to cope with a flat bottom surface that may be exceptional.

The height of the peripheral side plate 1b is preferably as small as possible. As long as the speed and amount of the air jets ejected from the nozzle part 3 are the same, the container-like device body 1 has a higher drainage capacity as its height dimension is smaller.
Further, in this embodiment, the container-like device body 1 is configured as a square member in plan view of the lower opening, but is not limited thereto, and is rectangular in plan view, a triangle or a polygon more than a pentagon, a circle, an ellipse. It is also possible to configure in a shape or indefinite shape.

  As shown in FIG. 1 (b), the drainage port 2 is an opening that opens to the front end side of the container-like device body 1. The front end side means that the drainage port 2 is opened and the drainage port is opened. Since the air jet is configured to be ejected toward 2, the portion where the drainage port 2 is opened should have been so. In this embodiment, the drain port 2 is opened in a part of the peripheral side plate 1b. However, the drain port 2 may be opened in a part of the top plate part 1a, or the peripheral side plate 1b and the top plate part 1a. It is good also as opening near a boundary.

  As shown in FIG. 1 (b), the drainage guide pipe 4 is a rigid tube connected and fixed to the drainage port 2, and FIGS. 1 (a), 1 (b) and 2 (a), (b) As shown in FIG. 2, the drainage port 2 extends obliquely upward. The angle and length of the drainage guide pipe 4 should be determined in consideration of the height and distance of the barrier to be passed between the drainage target site using the drainage device and the destination to which the drainage target water is transferred. is there.

  The inner diameters of the drain outlet 2 and the drain guide pipe 4 are determined in consideration of the amount of drainage per unit time.

  As shown in FIGS. 1 (b) and 2 (b), the nozzle portion 3 is, in this embodiment, an L-shaped configuration in which the rear portion is fixed to the inner surface of the top plate portion 1a of the container-like device body 1. It is supported by a fixed piece 5 and its tip is extended and inserted into the drain port 2. The rear end of the nozzle portion 3 is connected to one end of a hose member 6 whose other end is connected to a compressor 8 (see FIG. 3A), and receives the compressed air generated by the compressor 8 at the rear end. It is designed to be able to erupt from. As described above, the L-shaped fixing piece 5 is welded and fixed to the inner surface of the top plate portion 1a as described above, and the nozzle portion 3 is passed through a mounting hole opened in the vertical portion. A fixing member that penetrates forward and backward is fixed to a vertical portion of the fixing piece 5. The rear end of the nozzle portion 3 is connected to the hose member 6 as described above. The hose member 6 is externally attached to the rear end of the nozzle portion 3 and the state thereof is tightened. The exterior state is fixed by tightening. In this embodiment, the hose member 6 is pulled out to the outside through a through-hole that is opened in a part of the peripheral side plate 1 b on the rear side of the container-like device body 1.

  The drainage device according to the first embodiment is configured as described above. Therefore, as described below, for example, the drainage device is useful for draining water to be drained such as rainwater staying on the solid foundation 7 during construction. Can be used for

  When using this drainage device, this device is first set on the drainage target portion where the drainage target water stays, for example, the solid foundation 7 where the rainwater stays as described above. As shown in FIG. 3 (b), such a set on the solid base 7 is such that the container-like device body 1 is placed with its opening down and the lower end of the peripheral side plate 1b is applied on the solid base 7. This is done by placing them in contact.

  As shown in FIG. 3 (a), the drainage guide pipe 4 is directly poured into the external side groove 9 or the like, or is inclined downward toward the side groove 9 or the like. Draining into a position where it can be discharged on an inclined road surface or one of the above two can be carried out in the next stage, for example, on a solid foundation 7 in a neighboring room partitioned by a rising portion of a foundation (not shown) Set the orientation and its tip position as possible. The setting of the state of the tip of the drainage guide tube 4 as described above is performed by moving the container-like device body 1 to a necessary position.

  When the drainage device is set in this way and the compressor 8 is operated, compressed air is generated by the compressor 8, and this compressed air is stored in a tank attached to the compressor 8, and drained through this tank. Will be supplied to the device. As shown in FIG. 3A, the compressed air is supplied through the hose member 6 to the nozzle portion 3 disposed inside the container-like device body 1. As shown in FIG. 3 (b), the nozzle portion 3 receives the compressed air at its rear end, accelerates it in a tubular space having a smaller diameter than the hose member 6, and ejects it from the nozzle at the tip. In this way, the air remaining in the container-like device main body 1 and the staying water entering the inside are sucked by the high-speed air jet ejected from the top of the nozzle portion 3. Along with this, the stagnant water outside the container-like device main body 1 is sucked into the container-like device main body 1 through a minute gap between the lower end of the peripheral side plate 1 b of the container-like device main body 1 and the surface of the solid base 7. Is done.

  Since most of the area where the water to be drained such as the solid foundation 7 stays is uneven, there is almost always a minute gap between the lower end of the peripheral side plate 1b. Even if the surface of the solid base 7 is completely flat, minute projections 1 bp, 1 bp... Are formed at the lower end of the peripheral side plate 1 b, so that the lower end of the peripheral side plate 1 b and the upper surface of the solid base 7 are There will always be a minute gap between them. Therefore, suction of the staying water through this minute gap is surely performed.

  As shown in FIG. 3 (b), the staying water outside the container-like device body 1 is sucked into the inside of the container-like device body 1 and guided to the drain port 2 together with the air jet and connected to the drain guide tube 4 connected thereto. In this way, the water is discharged on the solid foundation 7 in the adjacent chamber, in the external side groove 9 or on the inclined road surface connected thereto, so that the accumulated water such as rain water can be drained. When draining onto the solid foundation 7 in the adjacent room, the drainage device is used again to perform the draining operation in the same manner, and drains to the external side groove 9 or the like.

  Further, as shown in the figure, in the case where the water level is high and the water surface ws is located above the top plate portion 1a of the container-like device main body 1, it is natural that the peripheral side plate 1b and the solid foundation 7 below it are provided. The stagnant water is suctioned and drained through a minute gap with the surface, etc., but even if the water level drops with the drainage operation and falls below the height of the upper end of the minute gap, this gap Since, literally, it is a minute gap, the suction drainage operation is possible and the drainage operation is continued well. Further, if the operation is continued even after the drainage operation is completed, the operation for drying the drainage target portion after the drainage is subsequently performed.

  Even if the water level of the drainage target portion becomes extremely low, for example, about 5 mm or less, as described above, the interval between the lower end of the peripheral side plate 1b and the bottom surface of the drainage target portion is a minute gap. Since the gap is a very narrow gap of about 1 mm or less, the drainage operation can be continued. Furthermore, the drying operation is also possible. The amount of drainage per unit time can be secured by making the container-like device body 1 large. Of course, as the size increases, the amount of compressed air from the compressor 8 also increases, but the extent can be determined experimentally.

  When the water level falls, the sucked-in retained water is discharged from the tip of the drainage guide pipe 4 in the form of water droplets, and when it falls below, it becomes mist-like and discharged. After the bottom surface of the drainage target part such as the solid base 7 is almost wet, the external air is sucked through the minute gap below the lower end of the peripheral plate 1b by the above draining operation. As a result, air moves on the wet surface and promotes drying thereof.

  If mud remains on the solid foundation 7 that is the target of drainage, drain water into this area, stir it into mud, and perform drainage with this drainage device. It can be performed. If foreign matter is mixed in the staying water, if it cannot pass through the minute gap below the lower end of the peripheral side plate 1b, it will remain due to clogging. These clogged foreign substances can be easily removed after the drainage operation is completed. Moreover, since the diameter of the drainage guide pipe | tube 4 is not small, the foreign material which entered the inside of the container-shaped apparatus main body 1 will be discharged | emitted through this. A foreign object does not clog any part and cause a failure.

Thus, according to the drainage device of the first embodiment, it is possible to easily and surely perform the draining operation of the drainage target part, and finally, it is possible to perform the drying process of the part.
In addition, although the drainage process of the area | region where the gravel was laid was performed with the drainage apparatus of this Example 1, this was also able to be implemented favorably.

<Example 2>
As shown in FIG. 4, the drainage device of the second embodiment is the same as the first embodiment except that the nozzle portion 13 is different from the nozzle portion 3 of the first embodiment. In the figure, elements having the same configuration as in the first embodiment are denoted by the same reference numerals. As shown in the figure, the nozzle portion 13 has a nozzle hole at the front end thereof located immediately before the drainage port 2 and does not enter the interior of the drainage port 2 like that of the first embodiment. According to this nozzle portion 13, during the drainage operation, the water flow sucked by the air jet spouted from the nozzle hole at the tip of the nozzle portion 13 moves slightly as a jet flow toward the drain port 2 while spreading, All are in a positional relationship where they can enter the drainage port 2.

  Therefore, the drainage device of the second embodiment can be used in the same manner as the drainage device of the first embodiment, and the completely same effect can be obtained.

<Example 3>
As shown in FIG. 5 (a), the drainage device of Example 3 is configured such that its container-like device body 11 is circular in plan view, and therefore the top plate portion 11a is also circular in plan view. The side plate 11b is also arc-shaped when viewed from the bottom. The height of the peripheral side plate 11b is the same as that of the peripheral side plate 1b of the first embodiment. As shown in FIGS. 5A and 5B, the other components are all the same as those in the first embodiment, and the same reference numerals are used.

  Therefore, when the drainage device of this embodiment 3 is used in the same manner as the drainage device of embodiment 1, the accumulated water in the drainage target site can be sucked and drained through a minute gap below the lower end of the peripheral side plate 11b. The method of flowing the staying water is slightly different from that in the first embodiment, but the draining operation can be performed substantially similarly. The subsequent drying operation is also the same.

<Example 4>
As shown in FIGS. 6A to 6C, the drainage device of the fourth embodiment is the same as that of the first embodiment except that the passage route of the hose member 16 connected to the nozzle portion 3 is different from that of the first embodiment. The configuration is exactly the same. In FIG. 6, the same reference numerals are given to components having the same configurations as those of the first embodiment.

  In the fourth embodiment, the hose member 16 having one end connected to a tank attached to the compressor 8 is guided to the inside through the peripheral side plate 1b on the front side of the container-like device body 1 as shown in FIG. Then, it is folded back and connected to the rear end of the nozzle portion 3. The connection method is the same as that of the first embodiment.

  As described above, since only the passage path of the hose member 16 is different from the first embodiment, when this drainage device is used for draining stagnant water at the site to be drained, it is natural. The same operation can be obtained with the same effect. That is, when the container-like device main body 1 of this drainage device is installed in the drainage target part and the drainage operation is performed, it goes without saying that the accumulated water in the drainage target part is sucked and drained through a minute gap below the lower end of the peripheral side plate 1b. Therefore, since the positional relationship of the hose member 16 is slightly different from that of the first embodiment, the flow of staying water accompanying the drainage operation is slightly different from that in the first embodiment, but substantially. A similar draining operation can be performed. The subsequent drying operation is also the same.

  However, in the fourth embodiment, the hose member 16 is pulled out from the front side portion of the peripheral side plate 1b of the container-like device body 1 in the same manner as the drainage guide pipe 4, and in many cases, the compressor 8 Since it is arranged on the extended side of the guide tube 4, it is often convenient at the time of installation to the drainage target part because of the relationship.

<Example 5>
In the fifth embodiment, as shown in FIGS. 7A and 7B and FIGS. 8A and 8B, the dimensions in the height direction of the peripheral side plate 21b of the container-like device body 21 and the drainage guide tube 24 are shown. The configuration is exactly the same as those of the first embodiment, except that the mounting angle to the peripheral plate 21b and the position of the tip of the nozzle portion 23 are different from those of the first embodiment. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals.

  As shown in FIGS. 7 (a) and 7 (b), the peripheral side plate 21b is constructed such that the height of its front part is high, that of its rear part is low, and that of both sides is that of the front and rear. It is comprised in the shape of an inclination which connects. Other configurations of the container-like device body 21 are the same as those of the container-like device body 1 of the first embodiment. The drainage guide tube 24 itself has the same configuration as the drainage guide tube 4 of the first embodiment. However, the method of attaching the front side of the container-like device body 21 to the peripheral side plate 21b is the same as that of the peripheral side plate. It is configured to project at a right angle to the surface of 21b. Further, the nozzle portion 23 extends linearly until just before the drain port 2. As described above and as shown in FIGS. 7B and 8B, the nozzle hole at the tip of the nozzle portion 23 is located immediately before the drain port 2 and is ejected from the nozzle at the tip of the nozzle portion 23. A drainage jet that moves while gradually expanding along with the air jet is generated, but the positional relationship between the tip jet port of the nozzle portion 23 and the drain port 2 is that all of the drain jet flows into the drain port 2. There is a certain distance relationship.

  Therefore, when the container-like device main body 21 of the fifth embodiment is installed on the bottom surface of the drainage target portion which is a flat surface, the height of the peripheral side plate 21b on the front side is high, so the outer surface of the peripheral side plate 21 is inclined upward. Naturally, the drainage guide tube 24 is inclined upward toward the tip. For example, when draining rainwater that has accumulated on a solid foundation 7 of a building under construction, it becomes possible to drain it beyond the surrounding foundation rising portion.

  Therefore, according to the drainage device of the fifth embodiment, the same effect can be obtained by using it almost in the same manner as the first embodiment.

<Example 6>
In Example 6, as shown in FIGS. 9A to 9C, the nozzle 33 and the hose member 36 are attached to the container-like device main body 31, and the drainage guide pipe 34 is attached to the container-like device main body 31. On the other hand, the configuration is exactly the same as that of the first embodiment except that the height of the peripheral side plate 31b of the container-like device body 31 is different from that of the first embodiment.

  As shown in FIGS. 9A to 9C, the nozzle portion 33 has a spacer plate 35 a fixed on the lower surface of the top plate portion 31 a of the container-like device body 31 and is in contact with the lower surface. The nozzle portion 33 is fixed to the spacer plate 35a by the mounting member 35b. This fixing is performed by holding the nozzle portion 33 with a partial arc-shaped concave portion 35b1 in the central portion and fixing the attachment plates 35b2 and 35b2 on both sides to the spacer plate 35a.

  As shown in FIGS. 9A and 9B, the hose member 36 is also fixed by a similar member having a slightly larger size. That is, the hose member 36 has a spacer plate 35c fixed to the lower surface of the top plate portion 31a of the container-like device body 31, and is disposed in contact with the lower surface. The hose member 36 is attached to the mounting member 35d. It is fixed to the lower surface of the spacer plate 35c. This fixing is performed by holding the hose member 36 with a partial arcuate recess 35d1 at the center and fixing the attachment plates 35d2 and 35d2 on both sides thereof to the spacer plate 35c by welding.

  As shown in FIGS. 9 (a) and 9 (b), the drainage guide pipe 34 has a base portion fixed at a position extending from the top plate portion 31a of the container-like device body 31 to the peripheral side plate 31b. It was launched at an angle. Naturally, the drain port 32 is also opened at a position corresponding to the base portion. Further, the nozzle hole at the tip of the nozzle portion 33 is disposed in the drainage port 32 in an entering state.

  Therefore, in the drainage device according to the sixth embodiment, as described above, since the nozzle portion 33 and the hose member 36 are attached to the top plate portion 31a as described above, the height of the peripheral side plate 31b of the container-like member 31 is increased. It is possible to reduce the dimension in the vertical direction, and the sixth embodiment is configured to be as low as possible.

  Therefore, according to the drainage device of the sixth embodiment, it is possible to perform the drainage treatment of the drainage target site using almost the same as in the first to fifth embodiments, and the compressed air similar to the other first to fifth embodiments. Under such conditions, a larger amount of wastewater treatment can be performed more efficiently.

  The drainage device of the present invention can be used in the industrial field for producing it and in the field of wastewater treatment using the same.
