Description

  The present invention relates to a waterproof insect repellent device having a fitted box-shaped case inserted between a lid of a drainage basin for rainwater or the like and a receiving basin.

In the urban area, Japanese Patent Application Laid-Open Publication No. HEI 9-102790 discloses a method for preventing odors and mosquitoes from leaking to the outside from rivers or sewage channels having a channel formed underground as a flow path, and draining water in a short time even in the case of large water. There is one disclosed in JP-A-7-26615. In this method, a water receiving plate is supported by a support shaft, cylindrical drain pipes are provided on the left and right sides thereof, and water is drained from a minimum opening provided at the bottom. The spring and the mounting rod at one end usually maintain the balance of the support plate on the water receiving plate, but when large amounts of water come in, the balance is lost and the water receiving plate rotates and discharges via the support shaft. Things. The odor rise is blocked by placing a ball in the drain pipe and closing the minimum opening provided at the bottom.

This type of conventional device requires a weight and a spring for balancing the rotation in order to support the water receiving plate in a balanced manner, and requires maintenance replacement due to damage of the spring. Because of the balance system in which the receiving plate rotates, the minimum opening provided at the bottom of the cylindrical drainage pipe must be reduced for deodorization and insect control. The drawback is that garbage that flows in with rainwater blocks the entrance of the drainpipe, or a net must be fixed at the drainpipe entrance to prevent the inflow of garbage. was there. When the water is increased, the rotation of the water receiving plate is reversed, so that the spring is easily damaged.

The problem to be solved by the present invention is to provide a waterproof insect repellent device which can be used in a rainwater drainage basin having a simple structure, which is very easy to maintain and has an insect repellent and deodorant effect, in view of these disadvantages. It is in.

  According to the present invention, a relatively large ball, for example, a circular hole of about 10 cm is formed in a bottom plate of a box-shaped case fitted in a drainage basin for rainwater or the like, and a spherical float (floater) is formed in the circular hole. ) Is fitted, and a rod-shaped mounting rod is attached to the lower part of the float. The mounting rod is freely movably inserted into and fitted to a positioning plate mounted on the bottom of the main body case, thereby preventing the mounting rod from coming off from the bottom of the case.

With this structure, when rainwater flows in, the float rises, and small dust easily flows out with the rainwater from the relatively large round hole. In the case of large water, the float floats up to the full length of the mounting rod, and a large amount of water flows smoothly from the round hole. The round hole can be closed with a float to prevent the smell of sewage and the rise of insects such as mosquitoes.

Embodiment 1 shows one embodiment of the present invention.
Embodiment 2 Embodiment 2 shows another embodiment of the present invention.

  The case of one float will be described. FIG. 1 is a schematic explanatory view schematically illustrating a drainage basin for rainwater, 1 is a drainage basin for rainwater, 2 is a drainage pipe, and 3 is a grating fitted on the drainage basin 1. Reference numeral 4 denotes a fitting type box-shaped case made of stainless steel, which is inserted and installed between a lid of a drainage basin for rainwater or the like and its receiving basin. A relatively large round hole 5 having a ball size of about 10 cm is formed at the center of the bottom P, and a spherical resin float 5 having a low specific gravity and floating in water is fitted into the round hole 5. A rod-like mounting rod is attached to the lower part of the spherical float 5 and usually functions to close the round hole 6. The mounting rod 6 has a structure in which the mounting rod 6 is fitted to a stainless steel positioning plate 9 attached to the bottom back surface 8 of the case 4 by freely movably passing through the positioning plate 9 to prevent detachment. The structure can be clearly understood in FIG. 2 showing a case where there are a plurality of floats 5.

  Each state at the time of fine weather, at the time of rain, and at the time of increasing water will be described with reference to FIG. 3. FIG. 3A shows the fine weather, and the float 5 closes the hole 6 at the bottom of the case 4. It blocks insects such as rising odors and mosquitoes. FIG. 6B shows a rainy weather. The rainwater flowing from the grating 3 into the case 4 lifts the float 5 and opens the round hole 6. You. FIG. 3C shows that when the amount of water in the case 4 increases due to heavy rain or the like, the float 5 floats up from the hole 6 and escapes the rising water to the ground as indicated by an arrow 12 to prevent the grating 3 from jumping.

This embodiment shows a case where a plurality of floats 5 are provided in the top view of FIG. In this example, the case 4 is large, and five round holes 6 are formed in the bottom P. FIG. 2 shows a perspective cross-sectional view as viewed from the direction of arrows AA. The flange 13 of the case 4 is fitted between the square 1 and the grating 3. FIG. 5 shows a simulated sectional view for understanding. A large number of large holes 6 are formed in the bottom P of the case 4 so that rainwater and dust can be easily discharged. The rod-shaped mounting rod 7 of the float 5 has a structure in which it is movably fitted and fitted to the stainless steel positioning plate 9 mounted on the bottom back 8 of the case 4 as described above to prevent the float 5 from coming off.
As shown in FIG. 6, when rainwater accumulates in the case 4, the float 5 rises by buoyancy from the hole 6 on the bottom P, the large hole 6 is in an open state, and a large amount of rainwater is quickly collected together with dust as indicated by an arrow 14. Flows. When the pore size is 5 cm to 10 cm, a considerably large amount of dust such as leaves can be released.

  Although the float 5 has been described as being made of resin, it may be made of copper. The mounting rod 6 may be made of stainless steel or resin.

The positioning means for preventing the float 5 from falling out of the case 4 is constituted by the mounting rod 6 of the float 5 and the positioning plate 9, but the X-shaped covering leg material fitted to the four corners of the case 4 presses the positioning means. To prevent slipping out.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic explanatory view illustrating a first embodiment of the present invention. 1 is a perspective sectional view illustrating an embodiment of the present invention. FIG. 3 is an explanatory diagram illustrating an embodiment of the present invention. FIG. 4 is a top view of a second embodiment of the present invention. It is explanatory sectional drawing of Example 2 of one Example of this invention.
