Description

Technical Field

[0001] The utility model relates to the field of trapping devices, and specifically to a wall-mounted trapping and collecting device for Pomacea canaliculata. Background Art

[0002] Pomacea canaliculata ( Pomacea ) is native to South America and was introduced into China in the 1980s. It is a freshwater snail listed by the International Union for Conservation of Nature in the world's 100 most invasive alien species, and has caused serious agricultural and ecological hazards worldwide. Pomacea canaliculata has a wide adaptability, strong stress resistance, and high reproductive rate, and has a significant competitive advantage over native species. Its invasion has reduced local biodiversity and formed a vicious cycle.

[0003] At present, the prevention and control technologies for Pomacea canaliculata mainly include chemical control, physical control, biological control, and plant-source snail control. Chemical control is carried out by applying molluscicides such as niclosamide, yomesan, and metaldehyde, which has obvious effects in closed water bodies, but is prone to environmental pollution and harms other organisms; the physical control method is mainly to remove and capture in time after artificial induction of spawning. This method needs to be carried out continuously, and a large amount of labor costs are invested and it cannot be eradicated; the biological method mainly uses the "food chain" to control snails by raising ducks, fish, crabs, etc. However, most poultry do not like to eat Pomacea canaliculata, and the breeding range of poultry is not fixed. There is also a risk of parasite transmission when eating Pomacea canaliculata; for plant-source snail control, such as the extract of Eomecon chionantha has an inhibitory effect on the hatching of Pomacea canaliculata eggs and has a certain toxic effect on its juvenile and adult snails. However, at present, this technology is still in the experimental research stage and has not formed a large-scale product.

[0004] At present, the prevention and control methods for Pomacea canaliculata in urban rivers mainly adopt artificial removal of egg masses and picking up adult snails, and harmless treatment is carried out on the picked-up Pomacea canaliculata and snail eggs. It consumes a lot of time, manpower, material resources and financial resources, and has low efficiency.

[0005] Therefore, there is an urgent need to develop a trapping device for Pomacea canaliculata that is low-cost, environmentally friendly, effective, and sustainable. Content of the Utility Model

Specific implementation mode

[0020] To make the purpose, principle and structure of the present utility model clearer, the following further elaborates in conjunction with the attached drawings and specific embodiments.

[0021] The present utility model provides a wall-mounted Pomacea canaliculata trapping and collection device, including a collection box 1, an equipment box 2, an anti-screw thorn pad 5, and an anti-screw floating body 1.6. The collection box 1 is in the shape of a cuboid, the surrounding of the box is sealed and light-tight, and a bait bin is arranged inside. The collection box 1 is sleeved or embedded at the lower end of the steel pipe hook 3 through connecting pipes 4 with different diameters, and the whole device is fixed on the coping of the vertical retaining wall of the river through the steel pipe hook 3. The equipment box 2 is embedded in the collection box 1; the equipment box 2 includes a solar panel 2.3, a storage battery 2.2, and a lamp bead 2.4. Pomacea canaliculata enters the collection box 1 through the notch of the anti-screw floating body 1.6 and the opening at the lower end of the collection box 1 and passes through the one-way curtain. The anti-screw thorn pad 5 avoids the trapping channel formed by the above settings to prevent Pomacea canaliculata from crawling out of the trapping device at will, improving the trapping efficiency.

[0022] During installation, the steel pipe hook 3 is fixed on the river retaining wall, the connecting pipe 4 is fixed on the equipment box, and the connecting pipe 4 is sleeved or embedded on the steel pipe hook 3 to make it displaceable up and down. The lower part of the collection box 1 is cooperatively connected with the anti-screw floating body 1.6, so that the device can move up and down with the river water level. Door openings 1.5 are opened on both sides of the box, and a trapping cavity 1.4 is arranged in the door opening 1.5. A trapping agent box is fixed in the trapping cavity 1.4 to attract Pomacea canaliculata in the attracting channel to enter. The two door openings 1.5 can be opened regularly to clean the Pomacea canaliculata captured in the device and place the trapping agent.

[0023] Inside the device box body 2, there are a solar panel 2.3, a light control switch 2.5, a storage battery 2.2, etc. These devices are connected in series with each other. When there is sufficient sunlight, it stores electricity for the storage battery. In a dim light environment, the light control switch 2.5 is turned on and the lamp beads 2.4 are always on. Because the apple snail has a light avoidance property and will climb towards a dim light environment, this device can prevent the apple snail from laying eggs in the trapping channel.

[0024] Except for the trapping channel, anti-snail spiked pads 4 are evenly distributed on other contact surfaces. The anti-snail spiked pad 4 is a backing plate covered with dense spikes. The dense barbs make the apple snail lose its adhesion at the place where the backing plate is laid, preventing the apple snail from climbing onto the floating body and only allowing it to climb through the trapping channel where the anti-snail spiked pad is not pasted. A one-way curtain is arranged inside the channel, and the curtain opens unidirectionally. The single lightweight plastic rod on the curtain hangs down by its natural gravity and is stuck by the inclined plate, unable to open in the reverse direction, achieving the trapping effect.

[0025] In summary, the apple snail trap provided by this solution is simple to operate, convenient to install, modularly arranged, physically traps, does not require power supply, has a long collection and maintenance time period, and does not require manual attendance. At the same time, it can effectively prevent the apple snail from escaping and has a good trapping effect on the vertical retaining wall revetment in the river channel.

[0026] The above is only the specific implementation manner of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by this utility model, according to the technical solution and the new concept of this utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of this utility model.
