BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a drainage outlet of a drainage hose and to a device for preventing pressure drainage from scattering.

There are two types of conventional drain hoses, one of which has a cylindrical hose connection fitting and the other of which is a cut portion of a vinyl hose. Is always draining while holding the tip by hand, but if you loosen your hand slightly and loosen the tip, the tip will flutter and the drainage will scatter on the road, which is currently a problem .

[0003]

[Problems to be Solved by the Invention] The drainage of the water in the manhole is performed by a pump car or the like from the grating lid of the drainage gutter on the road. Since there was no article between the tip and the grating lid that allowed drainage to flow smoothly, the drainage was scattered on the road. In this case, the present invention is intended to provide a pressure drainage scatter prevention device which is attached to a base portion at a tip of a drainage hose and gently guides drainage into a gutter to improve a working environment.

[0004]

The above object can be attained by adopting the following novel characteristic constitution means of the present invention. That is, the first feature of the present invention is a conical shape,
Alternatively, the present invention is a pressure drainage scattering prevention tool in which a socket in which a pluggable fitting socket at the end of a drain hose is fitted is fitted to an outer end of a mounting pipe that penetrates one outer periphery of a hollow cylindrical object. .

[0005] A second feature of the present invention is a pressure drainage scatter prevention device comprising a jet diverter set inside a hollow object attached to the inner end of the mounting pipe in the first feature.

[0006]

According to the present invention, the above measures are taken, so that the drainage from the gutter lid of the gutter to the road portion is drained without being scattered. It is fixed and installed without losing the drainage pressure diverted by the above, eliminating the necessity of the conventionally required personnel for holding the hose tip. In addition, if a conical safety cone is used in the present invention, it becomes a construction sign and has a safety effect.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a front view of the present embodiment, FIGS. 2 and 3 are a partial vertical cross-sectional side view and a partial cross-sectional plan view of the present embodiment, and FIG. 4 is an explanatory view of an installation state of the present embodiment. The pressure drainage scattering prevention device A of this embodiment is a conical outer peripheral lower part of a hollow safety cone 2 in which a sewer vinyl chloride joint 1 as a jet diverter capable of deflecting a jet vertically is set. At the outer end of the mounting pipe 3 that penetrates the wall surface, a socket 6 that can be fitted one-touch with a plug-in fitting socket 5 at the end of a drainage hose 4 guided by a drainage pump truck, and at the inner end is a sewer PVC joints 1 are attached. The attachment pipe 3 facilitates the attachment of the hollow portion of the safety cone 2 to the socket 6 and the socket 6
In order to measure the fusion between the diameter and the PVC joint 1 for sewage, a splicing medium is used.

In the drawing, reference numeral 7 denotes an L-shaped free end of mounting stays 10, 10 which have one end fastened by bolts 9, 9 embedded in an inner collar 8 at the base end of the safety cone 2 and project radially. A hose band which is wound on the lower end of the PVC joint 1 for sewerage and clamped on the both sides to measure the tightening stability, 11 is a seat plate, a is an iron grating cover (mesh) Lids) and b are lids of concrete gutters on both sides or one side of the road, and c is a pedestrian road boundary block. It should be noted that a hollow cylindrical hollow object may be adopted in place of the conical safety cone 2 in this embodiment, and in some cases, the sewer PVC joint 1 may be removed and used. Then, the discharge water spouted from the mounting pipe 3 collides with the opposing inner wall surface and makes the dispersion inferior.

Since the specification of the present embodiment is such a specific embodiment, in use, first, as shown in FIG. 5, a drainage pump car d is parked near the manhole e and the manhole e is parked. e, a suction hose f connected to a drainage pump car d is dropped, and then the drainage hose 4 in this embodiment is connected to a drainage port g of the main body of the drainage pump car d, and as shown in FIG. Seat plate 1 on lid a
The plug-in fitting socket 5 at the tip of the drainage hose 4 is fitted to the socket 6 of the safety cone 2 on which 1 is installed, and the preparation work is completed. In the figure, h is a safety cone, and i is a folding stand traffic sign board.

[0010] Thereafter, a pump (not shown) of the drainage pump car d is started to pump up the pooled water in the manhole e by the suction hose f, and the pressure drainage passes through the drainage hose 4 through the pump not shown. The forcible diversion socket is forcibly deflected up and down in the sewer vinyl chloride joint 1 through the socket 6 and the mounting pipe 3 from the fitting socket 5 at the tip to lower the drainage pressure by two minutes, and then up and down in the safety cone 2 , A discharge flow W indicated by a dotted arrow is shown.

[0011] That is, the drainage that has been jetted downward flows down into the gutter through the grating cover a. The water discharged upward is blown up to the top of the safety cone 2, but is guided by the conical inner wall surface of the safety cone 2 and falls outside the sewer PVC joint 1,
Again, it is drained and drained into the gutter via the grating cover a.

Therefore, the reaction and reaction of the jet pressure from the polyvinyl chloride joint 1 for sewerage are divided into two in the opposite direction, thereby canceling out as much as possible, and the remainder is discharged into the self-weight of the safety cone 2 and the inside. Combined with the weight of the water volume, it is suppressed against the impulse of a rampage or a snake, and is stopped on the grating cover a. In short, there is a function of sealing the jetting force of the discharge flow W in the safety cone 2.

[0013]

[Effects of the Invention] Thus, according to the method of use of the present invention, it is unnecessary to drain the hose by manually placing the tip end portion of the drainage hose on the grating lid, thereby reducing the number of working personnel. In addition, the safety cone and the grating lid are closely adhered to each other by the weight of the safety cone, and there is no scattering of drainage to the outside such as on a road. In addition, since the self-weight of the safety cone is higher than the pressure of the jet of the drainage pump, there is no floating phenomenon of the safety cone and the stability is good.

In addition, the appearance of the third person at the work site is only in a state where the safety cone is installed on the gutter, so that the appearance is good and the annoyance during construction is reduced, and the safety is also provided because the safety cone also serves as a safety facility. Be improved. Furthermore, since various types of manholes (NTT, electric power companies, water supply facilities) installed on the road generate accumulated water due to rainwater or the like, they exhibit excellent practicality and usefulness such as being optimal for this drainage work.
