DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insecticide / sterilizer used to suppress the generation of mosquitoes in stagnant water of rainwater squid and the growth of algae and pathogens in cooling water of a cooling tower.

[0002]

2. Description of the Related Art Rainwater troughs that collect rainwater or the like and drain the rainwater pipes are buried in residential lands or in road gutters. A drainage attachment pipe is connected to the side surface of the rainwater basin. The attachment pipe is usually connected so as to be located about 150 mm above the bottom surface, so that mud does not flow into the rainwater pipe. For this reason, the rainwater or the like that has flowed into the rainwater trough is not completely discharged by the mounting pipe, but stays at the bottom. The place where the rainwater stays becomes a spawning site for mosquitoes from spring to autumn, and a habitat for larvae (bottle fur), that is, a place where mosquitoes are generated. The occurrence of mosquitoes is not only unpleasant for public health, but also unpleasant for the local residents. In the past, insecticides were sprayed to prevent mosquito outbreaks and killed at the larval stage, but the effect of insecticides lasts for a relatively short time,
If it rains after spraying, there is a drawback that the drug cannot flow and the effect cannot be maintained.

Therefore, in recent years, a large number of containers containing water in which copper and tin having a bactericidal action are dissolved are arranged, and mosquitoes lay eggs there and kill hatched larvae to prevent the generation of mosquitoes (Japanese Unexamined Patent Publication No. 1-273534) has been proposed.

[0004] In the cooling water of the cooling tower, Legionella bacteria may propagate and scatter, causing disease. Examples of a method for disinfecting the cooling water or the like include a disinfection mat containing silver or copper (see Japanese Utility Model Application Laid-Open No. 63-32697) and a ball containing copper or silver (see Japanese Patent Application Laid-Open No. 63-185492). ), A disinfection device (Utility Model Registration No. 3039290) in which ultrafine copper fibers are provided in a case, and a supply device of copper or silver ions by electrolysis.

However, the conventional insecticidal and sterilizing methods utilizing the sterilizing action of copper and the like have the following problems. 1) In a method of preventing mosquitoes from being spawned by mosquitoes in a container filled with water in which copper and tin are dissolved, it takes time to prepare and arrange the containers, and leave the containers for a long period of time. And water evaporates and dries, and maintenance is troublesome. 2) Sterilization mats and balls containing copper or silver, and sterilization equipment in which ultrafine copper fibers are installed in a case, stains such as slime during use, and copper ions or silver having a sterilizing effect. Ions are less likely to elute. Therefore, it is necessary to periodically inspect the cooling tower and clean copper or silver members, which requires time and effort for maintenance. 3) A copper or silver ion supply device by electrolysis is expensive and is difficult to adopt for a small-scale cooling tower. 4) Since the shapes and dimensions of the insecticide and sterilization equipment (rainwater masu, cooling tower, etc.) are various, it is necessary to prepare various types of insecticide and sterilization equipment, which increases the cost. Was a factor. Also,
Depending on the form of the insecticide / sterilizer, it is difficult to prevent the flow of water in the facility, that is, rainwater or cooling water, or to make the contact area with the water sufficiently large, thereby lowering the insecticidal / sterilization efficiency.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and can be installed in a facility such as a rainwater basin or a cooling tower to supply copper ions having an insecticidal and bactericidal action. A simple and inexpensive insecticide / sterilizer that can be provided. That is, the invention according to claim 1 is an insecticide / sterilizer wherein a plurality of copper or copper alloy tubes are housed in a housing having a large number of communication holes. The invention according to claim 2 is characterized in that, in the invention according to claim 1, the length and / or the outer diameter of the tube are two or more. Further, the invention according to claim 3 is the invention according to claim 1, characterized in that it comprises a spill-prevention tool.

According to a fourth aspect of the present invention, there is provided an insecticide / sterilizer characterized by being a frame-shaped three-dimensional object formed from a copper or copper alloy frame. The invention according to claim 5 is an insecticide / sterilizer wherein a tube made of copper or a copper alloy is inserted into the frame of the frame-shaped three-dimensional object. The invention according to claim 6 is an insecticide / sterilizer characterized by being a three-dimensional object formed from a metal lath material made of copper or a copper alloy. Further, the invention according to claim 7 is an insecticide / sterilizer characterized by being a three-dimensional object formed from a perforated plate made of copper or a copper alloy.

According to the first aspect of the present invention, by accommodating a plurality of tubes in a container having a large number of communication holes,
Since the pipes come into contact with each other even with a slight sway due to the water flow and have the effect of removing dirt such as slime adhered to the surface, the pipes need only be installed in a rainfall or a cooling tower, and maintenance and management become easy. In addition, by using a plurality of copper or copper alloy tubes, they do not adhere to each other like a plate, and the supply area of copper ions does not decrease during use. In particular, when the length and / or the outer diameter of the pipes are two or more as in the invention of claim 2, a plurality of pipes occupy random positions or easily turn in random directions. The effect of removing dirt such as slime is improved. Furthermore, as in the third aspect of the present invention, if a spill-prevention tool (for example, a string or a hook) is provided, the stored object can be fixed at a desired position in the facility so as not to be washed away by running water.

According to the fourth aspect of the present invention, since the frame-shaped three-dimensional object is formed from a frame (linear body) made of copper or a copper alloy, it does not obstruct the flow of rainwater, cooling water, and the like. . Further, when a pipe made of copper or a copper alloy is inserted into the frame of the frame-shaped three-dimensional object as in the invention according to claim 5, the flow of rainwater, cooling water and the like is not obstructed, and the inner surface of the pipe Dirt such as slime adhered to the surface easily comes off due to contact with the frame.

According to the sixth aspect of the invention, when the three-dimensional object is formed of a metal lath material made of copper or a copper alloy, the contact area with water can be increased without obstructing the flow of rainwater, cooling water, and the like. can do. Further, since the shape and dimensions can be easily changed, it can be used for various facilities. Here, the metal lath material is JIS A 55
As defined in 05 (in this case, a steel plate), a mesh is formed on a thin plate by a stretch cutting method, and has a shape as shown in FIG. 5, for example. As shown in FIG. 6, for example, the method of manufacturing the mesh-shaped metal lath material 3 is as follows.
A large number of cuts having a short length are made by the cutting tool 2 and are stretched in a direction perpendicular to the cuts to form a metal lath material 3.

Further, when the three-dimensional object is formed from a perforated plate made of copper or a copper alloy, the flow of water is obstructed similarly to the metal lath material according to the sixth aspect. And has the advantage that the contact area with water can be increased. In addition, since the structure is simple, it is easy and practical to combine several perforated plates. In addition, the shape of the hole is preferably a polygon such as a circle, an ellipse, or a square for processing.
