The wiggler trapping and killing device provided by the embodiment has the following advantages: first, all-weather maintenance-free, adaptable to different climatic conditions. The cover plate 21 with the arc-shaped structure has a self-cleaning effect and can avoid the blockage of the water collecting hole 211, foreign matters are prevented from entering the barrel by the shielding effect of the outer edge of the cover plate 21 with the arc-shaped structure on the mosquito inlet hole 221, the foreign matters are further prevented from entering the barrel by the anti-convection design of the mosquito inlet hole 221, the rainwater cannot directly enter the spawning tank 32 due to the protection effect of the protection wall 34 on the spawning tank 32, the foreign matters or dirt carried by the rainwater is prevented from entering the spawning tank 32, the small-end opening of the conical tank 33 is prevented from being blocked by the foreign matters due to layer-layer limitation, and the device cannot lose efficacy after being used for a long time; meanwhile, the design of the floating cover 3 of the invention ensures that the evaporation water surface area is only the sum of the water surface areas of the spawning tank 32 and the conical groove 33, which is about equal to 1/4 of the water surface area of the water collecting barrel 1, compared with an open device, the evaporation speed of the accumulated water is reduced by more than 4 times, the stable water accumulation amount in the spawning tank 32 is ensured, and the volume of the device on the whole is not too large; sunlight cannot be directly injected into the barrel, so that the growth of algae and moss is avoided, and the small end opening of the conical groove 33 is further prevented from being blocked. And secondly, high efficiency and durability. The design of the protective wall 34 ensures that rainwater can only enter the tapered groove 33 and the spawning groove 32 from the small end opening of the tapered groove 33, and even if the rainfall is sufficient, the rainwater in the spawning groove 32 can be accumulated; the guide plate 35 facilitates the entry of wigglers into the tapered groove 33, thereby improving the catching efficiency. Thirdly, the trapping and killing effect is stable. The depth of the water in the spawning tank 32 does not change with the change of the water level in the water collecting bucket 1, but remains stable all the time, so the distance from the water surface in the spawning tank 32 to the small end opening of the tapered slot 33 is constant, i.e., the distance from the spawning tank 32 to the space inside the water collecting bucket 1 is the same at any time, and does not change with the change of the water level in the water collecting bucket 1, thereby ensuring the stability of the device. Fourthly, the environment is protected and the cost is low. The device only needs natural water to trap and kill the wigglers, does not pollute the environment, has low production cost, long action time and less manual maintenance, is suitable for large-scale popularization and application in residential areas such as cities, towns and the like, can greatly reduce the density of the mosquitoes, plays a role in inhibiting the breeding of the mosquitoes for a long time, and plays a role in preventing and inhibiting infectious diseases caused by mosquito bites.
The size of the wiggler trapping and killing device of this embodiment can be properly adjusted according to precipitation in different areas, when the device is used, a layer of stones 12 with the thickness of about 10mm needs to be placed at the bottom of the water collecting barrel 1, the stones 12 are soaked in rainwater, so that microorganisms can be bred, the attraction to female mosquitoes is improved, then, the water collecting barrel 1 is filled with accumulated water, and the purified tap water is not needed, but river water, pond water or water in a ditch is generally used, and then the water collecting barrel is sequentially filled with the floating cover 3 and the water collecting cover 2, the maintenance hole 212 on the water collecting cover 2 is screwed by the sealing cover 213, the wiggler trapping and killing device is installed at reasonable intervals by finding a place capable of carrying natural water near a residential area with dense mouths, one third of the lower half part of the device is buried underground during installation, the device is prevented from being blown down by strong wind, and then female mosquitoes are waited to lay eggs. Female mosquitoes enter the spawning tank 32 from the mosquito inlet hole 221 to spawn because of being attracted by accumulated water, the spawned mosquitoes incubate into wigglers after several days, the accumulated water in the spawning tank 32 is shallow, the wigglers can only move in the spawning tank 32 along the arc-shaped guide plate 35 and can be easily guided to the opening at the tail end of the arc-shaped guide plate 35 to enter the tapered groove 33 from the opening, the tapered groove 33 is easy to enter and difficultly exit, and because the wigglers have the habit of moving up and down, the wigglers can sink to the small-end opening in the tapered groove 33 and enter the space of the collecting bucket 1 (the space inside the collecting bucket) below the floating plate 31, the wigglers are difficult to reversely swim upwards due to the shielding effect of the baffle plate 331, only can grow in the inner groove 311 until the mosquitoes emerge, the mosquitoes can not find an outlet in the inner groove 311, the mosquitoes can not naturally die after several days, oxygen in the inner groove 311 gradually decreases due to the respiration of the wigglers, after a period of time, the later entering wigglers are suffocated and die due to oxygen deficiency, and cannot emerge into mosquitoes, so that the aim of killing the wigglers is fulfilled. The wigglers just hatched are very small, so as to avoid moving to the overflow holes 11 along the gap between the floating plate 31 and the water collecting barrel 1 to escape (in a full water state), a filter screen is added to the overflow holes 11 to prevent the wigglers from escaping, but after the wigglers grow up to become comma-shaped, the wigglers will be larger than the gap between the floating plate 31 and the water collecting barrel 1, and the wigglers will not emerge into mosquitoes in the gap between the floating plate 31 and the water collecting barrel 1.
The wiggler trapping and killing device that this embodiment provided, its cover 3 that floats makes the evaporation area only 1/4 of water collecting bucket 1 surface of water area, evaporation speed only has the 1/4 of open design promptly, only need fill up once water and can guarantee that the whole year can not be evaporated futilely, under the condition of extremely few rain, even if the evaporation of water in the water collecting bucket 1 has evaporated to dryness, because the tip opening of bell jar 33 lower part and the distance of baffle 331 only have 3mm, adult mosquito also can't escape from this place, consequently also need not add water by the manual work, it again automatic recovery function to have rained the device. Along with the ponding of laying eggs in the groove 32 slowly evaporates, the lid 3 that floats will slowly sink, but the surface of water in the groove 32 of laying eggs keeps unchangeable to the tip open-ended distance of tapered slot 33 for any wiggler is all the same from hatching to the distance that gets into the collector barrel inner space at any time, can not change along with the change of collector barrel 1 water level, thereby has guaranteed the stability of device. During rainy days, rainwater flows in from the water collecting hole 211, flows to the floating plate 31 along the connecting part 22 and the barrel wall of the water collecting barrel 1, and the upper part of the spawning tank 32 is provided with a protective wall 34, so that the rainwater cannot directly flow into the spawning tank 32, and only can flow into the space of the water collecting barrel 1 below the floating plate 31 from the gap between the floating plate 31 and the water collecting barrel 1, and the water in the spawning tank 32 is ensured to be accumulated in rainy days, thereby ensuring that the device also has lasting attraction to female mosquitoes in rainy days.
For maintenance convenience, a maintenance hole 212 is designed at the top of the cover plate 21, the maintenance hole 212 is usually screwed by a sealing cover 213, when inspection is needed, the condition of the floating cover 3 can be observed only by opening the sealing cover 213, and once the opening at the lower end of the tapered groove 33 is blocked, dredging can be carried out through the maintenance hole 212. Meanwhile, if the water in the water collecting barrel 1 is found to be dry, water can be supplemented through the maintenance holes 212, the whole device does not need to be disassembled and assembled, and the maintenance is very convenient.
Example 2
In order to increase attraction of the wigglers trapping and killing device to mosquitoes and to better facilitate popularization and maintenance, as shown in fig. 4, embodiment 2 provides a trash can, which includes a can body 4 and wigglers trapping and killing devices, the wigglers trapping and killing devices are arranged at the top of the can body 4, and more mosquitoes are around the trash can, so that female mosquitoes can be better induced to lay eggs.
