The insecticidal sterilization appliance includes: an insecticidal sterilizer holding body 10 having the water contact type solid insecticidal sterilizer 20 and a float part 15 provided on an outer periphery of a vessel part 11 in which the water contact type solid insecticidal sterilizer 20 is contained; and a guide cylinder portion 5A which freely moves the insecticidal sterilizer holding body 10 in a perpendicular direction according to a water level inside the street inlet 2A and controls a horizontal moving range.

Description

  The present invention relates to an insecticidal sterilizer that prevents the generation of insects and fungi by holding a water contact type solid insecticide for underwater insecticidal sterilization in a water retention part where water is retained, such as rainwater and a storage tank. It is about.

  Several configurations have been proposed that attempt to prevent the generation of bow flares and mosquitoes in a water retaining portion where water such as rainwater and a storage tank stays (see, for example, Patent Documents 1 and 2).

  Japanese Patent Application Laid-Open No. 2004-228561 discloses a bow-flarring prevention tool that prevents the generation of a bowfra in a rainwater trough, and the bowfrar-raising prevention tool is used by being floated on water in a rainwater trough. Further, Patent Document 2 discloses a mosquito rainwater that prevents the occurrence of mosquitoes. In such a configuration, the copper member or the copper alloy member is fixed to a required portion where the rainwater is retained.

JP 2008-38578 A JP 2000-154589 A

  However, in the configuration disclosed in Patent Document 1, there is a possibility that the bow-flame prevention tool may flow out of the rainwater via an outlet provided in the rainwater. Here, in order to prevent the outflow of the bowfla generation prevention device, it is proposed to adopt a bowfla generation prevention device having a size larger than that of the outlet or the like. This causes a problem that the storage capacity of the rainwater is reduced. Also, if the depth of the rainwater is too shallow, the anti-bowler device will fall over and will not float properly, and in some cases, sand mud, etc. will accumulate on the anti-bowler device, preventing contact with water. There was also a risk that the insecticidal effect could not be obtained.

  Even in the configuration disclosed in Patent Document 2, sand mud or the like accumulates or settles on a copper member or the like, and there is a problem that an insecticidal effect cannot be obtained. Moreover, since the copper member etc. are being fixed with respect to the rainwater, rust tends to arise in the part immersed in water for a long period of time. Since the rusted part has almost no insecticidal effect, it needs to be replaced. However, even if there is a part that has not yet rusted on the copper member, the entire part must be replaced, resulting in waste. Cheap.

  Then, an object of this invention is to provide the insecticidal disinfection instrument which can prevent the loss by the outflow of an insecticidal disinfectant in the water retention part in which water retains.

  The present invention relates to an insecticidal sterilizer for holding a water contact type solid insecticide used in insect killing in water in a water retention part where water is retained, the water contact type solid insecticide and the water contact type A float part for floating the solid insecticide on the water, and when the float is floated on the water in the water retention part by the buoyancy of the float part, the water contact type solid insecticide is added to the water in the water retention part. The insecticidal disinfectant holder that comes into contact with the insecticidal disinfectant holder that is floated on the water in the water retaining part is movable in the vertical direction according to the water level in the water retaining part, and has a horizontal movement range. An insecticidal sterilizing instrument, characterized by comprising a guide part for regulating.

  In such a configuration, the water contact-type solid insecticidal fungicide exhibits an insecticidal fungicidal effect on the water by contact with water, and is an aqueous solution that exhibits an insecticidal fungicidal effect until almost completely dissolved. Some of them are water-insoluble, and even if the insecticidal and sterilizing effect is lost, the outer shape remains almost intact without being completely dissolved. The water contact-type solid insecticide is in contact with water in a state of being floated on the water in the water retention part, and is immersed in water at a constant depth regardless of the fluctuation of the water level in the water retention part. For this reason, the amount of the water contact-type solid insecticidal fungicide that comes into contact with water becomes constant, and the insecticidal fungicidal effect is stably maintained. In addition, since the guide part regulates the horizontal movement range of the insecticidal disinfectant holder, the insecticidal disinfectant holder is prevented from accidentally flowing out of the water retention part and lost. There is no end to it. Since the guide member allows the vertical movement of the insecticide / sterilant holder, the insecticide / sterilizer holder can be appropriately floated according to the water level in the water retention portion.

  Further, the guide portion is a guide wall portion projecting from the inner peripheral surface of the water retention portion, and the insecticide / sterilant holding body is surrounded by the guide wall portion and the inner peripheral surface of the water retention portion. In addition, it may be disposed in a space into which water in the water retention part can flow.

  In such a configuration, it becomes possible to guide the insecticidal disinfectant holder using a part of the inner peripheral surface of the water retaining part, so that simplification of the insecticidal sterilizing instrument and space saving of the water retaining part can be achieved. .

  Further, the guide portion is a guide tube portion disposed in a substantially vertical direction in the water retention portion, and a water permeable portion is formed on a side wall of the guide tube portion, and the water is passed through the water permeable portion. The insecticidal disinfectant holder may be disposed in the guide tube portion into which water in the retention portion flows.

  In this configuration, the guide tube portion can be disposed at a desired position in the water retention portion, so that the degree of freedom in design is improved. Moreover, since the insecticidal fungicide holder is disposed in the space surrounded by the side wall of the guide tube portion, it is possible to reliably prevent the insecticidal fungicide holder from flowing out.

  Further, the guide portion is a guide column portion disposed in the water retention portion along a substantially vertical direction, and the insecticidal disinfectant holder is opened in a substantially vertical direction, and is formed outside the guide column portion. A through hole having a larger diameter than the diameter may be formed, and the guide column portion may be inserted into the through hole of the insecticide / sterilizer holder.

  By adopting such a configuration, the insecticidal disinfectant holder floated on the water in the water retention part can be moved in the vertical direction according to the water level in the water retention part, and the horizontal movement range can be achieved by a simple structure. It becomes possible to regulate.

  Further, the guide part is a guide engaging part provided along the substantially vertical direction on the inner peripheral surface of the water retaining part, and the insecticidal disinfectant holder is engaged with the guide engaging part. The insecticidal disinfectant holder is provided in the vertical direction in accordance with the water level in the water retaining portion along the guide engaging portion in a state where the engaging portion is engaged with the guide engaging portion. It is good also as a structure which is freely movable and the movement range of a horizontal direction is controlled.

  Even in such a configuration, the insecticide disinfectant holder floated on the water in the water retention part can be moved in the vertical direction according to the water level in the water retention part, and the horizontal movement range can be regulated. It becomes.

  By the way, as a means for providing a float portion for the water contact type solid insecticide, a structure in which a coupling portion is provided on the outer surface of the water contact type solid insecticide and / or the outer surface of the float portion to directly bond each other. Is proposed. However, in such a configuration, when the water contact type solid insecticide is water-soluble, the water contact type solid insecticide is partially dissolved in water and the outer shape of the joint is changed. There is a possibility that the bond between the contact-type solid insecticide and the float part is released.

  Therefore, the water contact type solid insecticide is water-soluble, and the insecticide germicide holder has a container part in which the water contact type solid insecticide is accommodated and a water permeable part is formed on the side wall. The container portion is provided with the float portion, and the water contact type solid insecticide disinfectant comes into contact with the water in the water retention portion through the water permeable portion of the container portion of the insecticide disinfectant holder. The configuration is preferable.

  As described above, when the float portion is formed in the container portion in which the water-contacting solid insecticide is accommodated, even if the water-soluble water-contacting solid insecticide is dissolved in water and the outer shape is deformed, It is possible to prevent separation of the water contact type solid insecticide and the float part, and the water contact type solid insecticide can be kept floating in the water until the water contact type solid insecticide is used up. .

  Furthermore, in the initial state in which the insecticidal fungicide holder is disposed in the water retention part, the upper end portion of the water contact type solid insecticidal fungicide in the container part is located above the water level in the water retention part. A configuration is preferred.

  In such a configuration, the water-contacting solid insecticide is dissolved from at least a portion below the water level, and the water-contacting solid insecticide is sequentially lowered correspondingly. For this reason, an appropriate amount of the water contact type solid insecticidal fungicide is sequentially consumed, the insecticidal fungicide effect can be easily maintained, and the entire amount of the water contact type solid insecticidal fungicide can be used up without waste.

  Moreover, the said water contact-type solid insecticidal fungicide has the structure which is an aggregate | assembly of many grains.

  In this configuration, the water-contacting solid insecticide is easily dissolved in water, and the lower gap generated by dissolution of the lower part of the water-contacting solid insecticide in the container portion is formed in the water-contacting solid insecticide. Since it descends smoothly so as to fill the upper part of the disinfectant, an appropriate amount of the water contact type solid insecticide disinfectant always comes into contact with water.

  The insecticidal sterilizer of the present invention has an effect of preventing the insecticidal sterilizing agent from flowing out from the water retention part and being lost.

The insecticidal sterilizer concerning Example 6 is shown, (a) is the decomposition | disassembly top view, (b) is the decomposition | disassembly top view which shows the modification.

  Hereinafter, the Example which actualized the insecticidal disinfection instrument of this invention is described in detail. In addition, this invention is not limited to the Example shown below, A design change is possible suitably.

Example 1
As shown in FIG. 1, the insecticidal sterilizer 1 </ b> A holds a water contact type solid insecticidal fungicide 20 used for insecticidal sterilization in water in a rainwater trough 2 </ b> A as a water retaining part where water is retained. Here, the water contact-type solid insecticide bactericidal agent 20 is made of a water-soluble solid material, and exhibits an insecticidal and bactericidal effect by contacting with water and dissolving in the water. As the water contact type solid insecticide bactericidal agent 20, a known insecticide bactericidal agent for preventing the occurrence of boufra, mosquitoes and the like is preferably used, but a silver-based inorganic substance which is an aggregate of many grains already on the market. An antibacterial agent (trade name: Novalon Toagosei Co., Ltd.) is particularly desirable.

  More specifically, as shown in FIG. 1, an insecticidal sterilizer 1A includes a guide tube portion 5A as a guide portion provided in a rainwater basin 2A, and a water contact type disposed in the guide tube portion 5A. And an insecticidal fungicide holder 10 provided with a solid insecticidal fungicide 20.

  The guide tube portion 5A is composed of a cylindrical member disposed in the rainwater basin 2A along a substantially vertical direction, and a plurality of water permeable holes 6 as water permeable portions are formed on the side wall of the guide tube portion 5A. Yes. Then, the water in the rainwater 2A can flow into the guide tube portion 5A through the water-permeable hole 6. Further, the upper end opening of the guide tube portion 5 </ b> A is shielded by the lid portion 7. The dimension and shape of the water permeable hole 6 are not particularly limited, but water can smoothly flow into the guide tube portion 5A, and dust in the rainwater 2A does not flow into the guide tube portion 5A. It is desirable that the size is set to a certain level.

  Further, as shown in FIG. 2, the insecticidal disinfectant holder 10 disposed in the guide tube portion 5 </ b> A is disposed on the container portion 11 made of a bottomed cylindrical member and the outer periphery of the container portion 11. And a float unit 15. The container part 11 is made of a transparent resin material, and the container part 11 is filled with a water-contacting solid insecticide bactericide 20 that is an aggregate of many grains. A cap 13 is attached to the upper end opening of the container portion 11. In addition, a large number of water permeable holes 12 as water permeable portions are formed on the side wall of the lower portion of the container portion 11. Further, a flange-shaped engaging portion 14 is formed on the outer periphery of the container portion 11, and a float portion 15 is engaged around the engaging portion 14. The float portion 15 is formed of a molded body made of a material having sufficient buoyancy so that the insecticidal disinfectant holder 10 such as foamed plastic or foamed rubber floats on water.

  The insecticidal disinfectant holder 10 is floated on the water in the rainwater 2A by the buoyancy of the float 15 in the guide cylinder 5A. The insecticide bactericide 20 is in contact with the water in the rainwater 2A through the water-permeable holes 12.

  Here, as shown in FIG. 1, the guide tube portion 5A makes the insecticide / sterilizer holder 10 movable in the vertical direction in accordance with the water level in the rainwater 2A and regulates the horizontal movement range. Playing a role. The inner diameter of the guide tube portion 5A is set to a size that allows easy maintenance and management of the insecticidal disinfectant holder 10, cleaning work of sand mud and the like in the guide tube portion 5A, and the like.

  In the above-described configuration, the water contact type solid insecticide bactericide 20 in the insecticide bactericide holder 10 is immersed in water by a certain depth regardless of the height of the water level in the rainwater 2A. Therefore, the amount of the water contact type solid insecticide bactericidal agent 20 that comes into contact with water becomes constant, and the insecticide bactericidal effect is stably maintained. In addition, since the horizontal movement range of the insecticidal disinfectant holding body 10 is regulated by the guide tube portion 5A, the guide tube portion 5A is connected via the pipe connection port (particularly the outflow pipe connection port) 8 formed in the rainwater 2A. There is no possibility that the insecticidal disinfectant holder 10 will flow out of rainwater 2A. Further, since the water contact type solid insecticide bactericide 20 is accommodated in the container part 11 and the float part 15 is formed in the container part 11, the water contact type solid insecticide fungicide 20 is partially dissolved in water. Even if the outer shape changes, there is no possibility that the water contact type solid insecticide bactericidal agent 20 and the float 15 are separated and only the water contact type solid insecticide bactericidal agent 20 sinks to the bottom of the water.

  As shown in FIG. 2, in the initial state in which the insecticidal disinfectant holder 10 is disposed in the rainwater trough 2A, the upper end of the water contact type solid insecticidal disinfectant 20 in the container 11 is the rainwater. It is located above the water level in 2A and dissolves in order from the lower part disposed below the water surface of the water contact type solid insecticide bactericide 20, and the upper part of the water contact type solid insecticide bactericide 20 corresponds to this The water contact type solid insecticide disinfectant 20 in the part 11 is sequentially lowered so as to fill a lower gap caused by dissolution of the lower part. For this reason, the water contact-type solid insecticide bactericidal agent 20 is consumed in an appropriate amount sequentially, and the insecticidal bactericidal effect tends to be sustained. Moreover, since the water contact type solid insecticide bactericide 20 which consists of a silver type inorganic antibacterial agent which is an aggregate | assembly of many above-mentioned grains is all easily soluble with respect to water, The entire amount can be used up without waste.

  Furthermore, the said structure is easy to confirm the remaining amount of the water contact type solid insecticidal fungicide 20. For example, as shown in FIG. 1, when an operator opens the lid portion 7 of the insecticidal sterilizer 1A for inspection, the water contact type is passed through the transparent container portion 11 of the insecticidal disinfectant holder 10. If it can be visually recognized that the upper end portion of the solid insecticide 20 is above the water level in the rainwater 2, it can be seen that the water contact solid insecticide 20 is sufficiently retained. On the other hand, if the upper end is not visible due to being submerged under the surface of the water, or if it is below the reference line provided in advance in the container 11 and does not satisfy the specified amount, it is time to replenish. It turns out that the cap 13 of the container part 11 is opened and the water contact type solid insecticidal fungicide 20 is appropriately replenished. In order to make the remaining amount of the water contact-type solid insecticide bactericide 20 easily visible, the container part 11 may be made of a transparent material as described above, or formed on the upper end of the container part 11. You may make it confirm from the made opening part.
