Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buoyant body (hereinafter, referred to as a pump float) capable of floating a pump in a fluid such as water, and in particular, pumps raw water before treating turbid water into a treatment apparatus. The present invention relates to a device for sucking the supernatant water of raw water.

[0002]

2. Description of the Related Art Generally, in a civil engineering work site,
Underground excavation is a lot of work, and at that time, underground water sometimes springs out, and it is necessary to proceed with construction while discharging this water. Because of the turbid water contained, it was not possible to inadvertently flow into the drain, and this water was usually purified by a treatment device and the treated water was discharged. And since the turbid water treatment device as described above is very large, using it even for simple construction requires enormous costs, which increases the construction cost and is small. Of the processing equipment of this is being coveted. However, simply reducing the size of the processing apparatus has made it difficult to cope with any situation at the construction site. That is, even if the construction is small, the amount of water that springs out of the ground is not small, and when a large amount of turbid water is generated, it is extremely long to treat all turbid water with a small-sized treatment device. It was time consuming. Therefore, by sending relatively less dirty water from the raw water to the processing apparatus, efficient processing may be possible even with a small processing apparatus, but the above-mentioned apparatus has not been developed.

[0003] Among the conventional techniques, a technique for floating a pump in a fluid such as water is disclosed in Japanese Utility Model Laid-Open Publication No.
No. 76893 discloses one. The technical content is that a floating pump is provided with a balance float, and a floating pump is one in which a submersible pump is provided in a flow trapper pipe having a suction port that opens upward, and is provided on a water surface in a sewage treatment layer. Floating oil and scum were sucked together with water.

Further, as a technique for floating a pump as a scum guide device, there is a technique disclosed in Japanese Utility Model Laid-Open No. 4-33996. This technical content includes a moving float, a submersible pump provided on the moving float, and a nozzle provided at the upper end of the water surface of the submersible pump. It was intended to guide the scum in a certain direction by squirting onto the water surface.

[0005]

However, of the prior art disclosed in the above-mentioned utility model publication, the former is a device for sucking floating oil or scum by a pump, The suction opening that opens upward,
It was not to improve the suction effect, but only to make it easier to remove when something got entangled. Further, in the latter, it is a device for guiding scum while ejecting water sucked from below the float,
It lifted the pump but did not suck off anything.

In addition, since both of the above technologies have a structure in which the pump is rotated in water or directly sucked in water, even if the pump is used for sucking supernatant water in turbid water, the pump is operated in water. In the case of letting or opening the suction part in water, the whole raw water will vibrate or flow, and the sediment floats due to the convection of the raw water, and this sediment mixes with the supernatant water. Was something. That is, if only water with a low turbidity is to be sucked out of the turbid water to be treated, the effect may be diminished.

The present invention has been made in view of the above points, and has as its object to provide a pump float capable of sucking only supernatant water of raw water.

[0008]

According to the present invention, there is provided a pump comprising: a box-shaped pump receiving means made of a material having a low specific gravity; and a restricting means for restricting a floating direction of the pump receiving means.

The frame bodies 21 and 22 are connected to the upper and lower ends of the..., So that the whole constitutes an integral regulating means 2. And
The reinforcing members 12, 13 of the pump housing means 1 are provided with several flat portions 14, 15, 16, 17,.
The above-mentioned regulating rails 23, 24,... Are inserted through these flat portions 14, 15, 16, 17,..., And the pump housing means 1 is regulated by the regulating rails 23, 24,. It is like that.

Here, as shown in FIG. 2, the pump housing means 1 includes the box-shaped main body 1 and an opening 11a of the main body 11.
And the reinforcing member 1 attached to the bottom surface 11b

As a result, the opposing positions are pulled together, and the reinforcing members 12 and 13 are fastened with the main body 11 interposed therebetween. That is, the main body 11 is just sandwiched between the reinforcing members 12 and 13, and the main body 11 is not easily detached from the reinforcing members 12 and 13 by this sandwiching. This makes it possible to form the housing means integrally. In addition, by releasing the tightening, the main body 1
1 and the auxiliary members 12 and 13 can be separated, so that it is easy to replace any one of the above members. Further, the reinforcing members 12 and 13 are each formed of a quadrangular planar frame, and the main body 1 is provided around the four corners around the reinforcing members 12 and 13.

Are provided in each case, and two reinforcing members 12, 1 are provided.
When the three are integrally formed, the restriction holes 25 and 26 can be opposed to each other. That is, when the main body 11 is integrally formed by sandwiching the main body 11 between the reinforcing members 12, 13, the regulating holes 25, 26,... Of the respective flat portions 14, 15,. That is, the upper and lower regulating holes 25, 26,... Can be inserted along the rod-shaped (straight) regulating frames 23, 24,.

Next, the details of the regulating means 2 will be described. As shown in FIG. 3, the upper and lower frame members 21, 22 and the regulating frames 23, 24... I have. The connecting portion between the two may be formed by engraving a male screw on one side and a female screw on the other side and screwing them together, but may be configured so as not to be easily detached by welding. At this time, it is necessary to attach the auxiliary members 12 and 13 of the pump housing means 1 in advance after fixing the respective parts. Therefore, one of the frame members 21 that constitutes the base portion from the lower side moves from the regulating frames 23, 24,.
The auxiliary members 12 and 13 can be mounted by fitting the above-described regulating holes 25, 26... Into the regulating frames 23, 24. Then, each of the restriction frames 23, 24

The extension hose can be supported.

Next, the usage of this embodiment will be described.
As shown in FIG. 4, the pump 3 is housed inside the main body 11 of the pump housing means 1, and the suction part 31 of the pump 3 is located near the bottom of the main body 11. Then, the motor unit 32
The pump 3 is prepared by being placed so as to protrude slightly upward from the main body 11. At this time, since the main body 11 is made of a synthetic resin foam, the main body 11 can float in water. However, one pump 3 has a large weight because almost the entire pump 3 is made of metal. Thus, by adjusting the balance between the two, it is possible to make the upper opening surface of the main body 11 substantially coincide with the water surface. Therefore, by installing the present embodiment in which the pump 3 is accommodated in a shaft or a tank in which raw water is stored, supernatant water flows in from the opening side 11a of the pump accommodation means 1, and only the inflowing supernatant water Can be sucked by the pump 3.

As described above, by flowing the supernatant water of the raw water from the opening side 11a of the pump accommodating means 1, the motor section 32 is unlikely to be immersed in the water, unlike the case where the motor section 32 is immersed in the water. It is not necessary to do so, and the service life can be extended. The water sucked by the pump 3 is water that has flowed into the body 11 once,
The convection generated by the operation of the pump 3 stays inside the main body 11, and only the supernatant water can be sucked around the main body without causing any convection to lift up the sediment at the bottom.

It is needless to say that various embodiments can be adopted without departing from the spirit of the present invention. For example, in the above-described embodiment, only the pump housing means 1 is configured in a square box shape, but the box shape may be another shape, and four regulating rails may be used. Although the regulating section 2 is constituted by 23, 24,..., The number may be changed.

The main body 11 of the pump housing means 1 is made of a synthetic resin foam, but this material is not limited to a synthetic resin foam, and can be made of other buoyant members. If a large buoyancy can be obtained, it is possible to accommodate the heavy pump 3, and even in that case, the opening side 11 a of the main body 11 is
It is possible to suck a larger amount of supernatant water than the above embodiment while floating near the surface of the raw water.

Further, in using the above embodiment,
Although only the case of sucking the supernatant water of the raw water to be treated has been described, it can also be used in the case of sucking only the most purified supernatant water of the treated water in a treatment apparatus using a sedimentation tank or the like. In addition, it can be diverted when suctioning scum floating on the water surface in a sedimentation pond or the like.

[0018]

As described above, the present invention is characterized by comprising a box-shaped pump housing means made of a material having a small specific gravity, and regulating means for regulating the floating direction of the pump housing means. Since the pump float is the gist, the pump can be housed in the box-shaped pump housing means, and the pump housing means can be raised by force while housing the pump, so that the water flowing inside the pump housing means can be internally pumped. Can be sucked by the pump housed in the housing. Therefore, by preventing the vibration caused by the operation of the pump from being transmitted to the raw water to be treated, it is possible to suppress the occurrence of convection in the raw water without vibrating or flowing the entire raw water. Can be sucked.

The pump housing means is a pump housing means having a capacity capable of sufficiently housing the pump and a sufficient amount of liquid, so that the pump housing means accommodates the pump. The supernatant water of the raw water can be sufficiently introduced, whereby the suction of the supernatant water by the pump can be continuously performed, and the suction of the supernatant water can be realized efficiently.

Further, the present invention provides a box-shaped main body made of a material having a low specific gravity, a flat portion provided at several places of the main body, a plurality of restricting frames penetrating the flat portion, Since the pump float is also characterized by comprising a frame body supporting the regulating frame in parallel at both ends, a flat portion continuous with the main body can move along the regulating frame, and the main body rises due to buoyancy, Alternatively, when the main body descends due to a decrease in the water level accompanying a decrease in the raw water, the ascending and descending direction can be regulated. And, by directing the longitudinal direction of the regulating frame to the vertical direction, it is possible to surely move the regulating frame in the vertical direction at the time of ascent and descent, and in the shaft or tank where raw water is stored, the vicinity of the water surface is the main body Can be prevented from floating. Therefore, the supernatant water of the raw water can flow into the main body at an optimum place in the shaft or the tank.
