Description

Technical Field

[0001] This utility model relates to the field of water ecological protection technology, specifically to a bamboo-woven device for collecting and treating golden apple snails along the shore of urban lakes. Background Technology

[0002] The golden apple snail (Pomacea canaliculata) is a large freshwater snail native to South America and has been listed as one of the first invasive alien species in my country. It reproduces rapidly in urban lakes and waterways in southern my country, posing a serious threat to native aquatic plants, disrupting the ecological balance of aquatic bodies, and potentially spreading parasites, thus endangering public health.

[0003] Currently, the main methods for controlling golden apple snails include manual collection and chemical extermination. However, these methods have obvious drawbacks: manual collection is labor-intensive and inefficient, especially in the complex terrain of lake shores; while chemical extermination can quickly kill golden apple snails, it can easily cause secondary pollution to the water, harm other non-target aquatic organisms, and damage the ecosystem. In addition, many trapping devices on the market are made of plastic or metal, which are not only costly, but also cause new pollution problems after the devices are discarded. This is especially true in the shores of urban lakes, which are usually sloped and have irregular terrain, and existing collection tools generally lack good terrain adaptability.

[0004] Therefore, it is of great importance to design a bamboo-woven device for collecting and processing golden apple snails along the shores of urban lakes to address the aforementioned shortcomings. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a bamboo-woven device for collecting and treating golden apple snails along the shores of urban lakes. This device aims to solve the technical problems of secondary pollution, high cost, and poor terrain adaptability in existing methods for controlling golden apple snails.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bamboo-woven device for collecting and treating golden apple snails along the shore of an urban lake includes a snail collector woven from carbonized bamboo strips. A one-way movable curtain door is installed at the bottom of the front of the snail collector. Adjustable support legs are installed at the four corners of the bottom of the snail collector. A gravity crushing module is installed inside the snail collector.

[0008] The gravity crushing module includes a guide frame fixedly connected to the front and rear sides inside the screw collector. A crushing block is slidably connected to the top of the two sets of guide frames. A bearing plate is hinged to the bottom of the two sets of guide frames. A gravity trigger release mechanism is installed between the bearing plate and the crushing block.

[0009] The gravity-triggered release mechanism includes a trapping groove at the top of the support plate. The front and rear ends of the crushed block are slidably connected to the inner side of the guide frame through a stabilizing plate. Sliding grooves are provided on the left and right sides of the two sets of guide frames. The left and right sides of the two sets of stabilizing plates are slidably connected to the sliding grooves through sliders. An abutment block is fixedly connected to the outer side of one set of sliders. A moving guide rail is fixedly connected to the outer side of one set of guide frames and below the abutment block. A locking block is slidably connected inside the moving guide rail, and the top of the locking block abuts against the bottom of the abutment block. A linkage rope is fixedly connected between the locking block and the support plate. A guide rope wheel is rotatably connected to the connection point between the front end of the moving guide rail and the linkage rope.

[0010] As a preferred embodiment of this utility model, the crushing block is made of concrete or stainless steel, the crushing block is covered with a biodegradable material, and the bottom of the crushing block is fixedly connected with multiple sets of conical protrusions.

[0011] As a preferred embodiment of this utility model, both the front and rear ends of the top of the crushing block are fixedly connected with through rods, and multiple sets of counterweights are sleeved on the outer side of both sets of through rods. The top ends of both sets of through rods are threaded with positioning sleeves, and a reset lifting rod is fixedly connected to the center of the top of the crushing block.

[0012] As a preferred embodiment of this utility model, both sets of stabilizing plates are rotatably connected to rollers inside, and both sets of rollers are in contact with the inner sidewall of the guide frame.

[0013] As a preferred embodiment of this utility model, the screw collector has holes in multiple sets of side walls, and the bottom of the screw collector has a hollow design.

[0014] As a preferred embodiment of this utility model, the one-way movable curtain door is composed of multiple sets of flexible sheets, all of which are made of biodegradable plastic sheets. The top ends of the multiple sets of flexible sheets are hinged to the screw collector, and the bottom ends of the multiple sets of flexible sheets abut against the inner side of the screw collector.

[0015] As a preferred embodiment of this utility model, the top ends of the multiple sets of adjustable support legs are hinged to the screw collector via connectors, and the bottom ends of the multiple sets of adjustable support legs are threaded with adjustable support cone sleeves.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, a snail collector, a one-way movable curtain, adjustable support legs, and a gravity crushing module are designed in combination. The snail collector, made of carbonized bamboo strips, has a shallow basket-like structure with a certain depth, attracting and trapping golden apple snails. The carbonization process enhances the durability and corrosion resistance of the bamboo. The one-way movable curtain allows snails to enter only in one direction, preventing escape. The gravity crushing module uses gravity to perform preliminary harmless treatment of the snails. The adjustable support legs can be flexibly deployed according to the slope of urban lake shorelines.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0024] A bamboo-woven device for collecting and treating golden apple snails along the shore of an urban lake includes a snail collector 1 woven from carbonized bamboo strips. A one-way movable curtain door 2 is installed at the bottom of the front of the snail collector 1. Adjustable support legs 3 are installed at the four corners of the bottom of the snail collector 1. A gravity crushing module 4 is installed inside the snail collector 1.

[0025] First, the gravity crushing module 4 includes guide frames 401 fixedly connected to the front and rear sides inside the snail collector 1. Crushing blocks 402 are slidably connected to the top of the two sets of guide frames 401. A bearing plate 403 is hinged to the bottom of the two sets of guide frames 401. A gravity-triggered release mechanism 404 is installed between the bearing plate 403 and the crushing blocks 402. The snail collector 1 is a shallow basket-like structure with a certain depth, which is woven from carbonized bamboo strips. The carbonization treatment can enhance the durability and corrosion resistance of the bamboo. When the number of golden apple snails in the snail collector 1 gradually increases and they climb onto the bearing plate 403, when their total weight reaches a preset threshold, the rear end of the bearing plate 403 will sink due to gravity. The sinking of the bearing plate 403 will trigger the gravity-triggered release mechanism 404, which will release the locked crushing blocks 402. The crushing blocks 402 will then fall along the guide frames 401 under the action of gravity, completing an automated crushing process.

[0026] Furthermore, the gravity-triggered release mechanism 404 includes a trapping groove 405 formed at the top of the support plate 403. Both ends of the crushed block 402 are slidably connected to the inner side of the guide frame 401 via a stabilizing plate 406. Slide grooves 407 are formed on the left and right sides of the interior of both sets of guide frames 401. The left and right sides of both sets of stabilizing plates 406 are slidably connected to the slide grooves 407 via sliders 408. An abutment block 409 is fixedly connected to the outer side of one set of sliders 408, and an abutment block 409 is fixedly connected to the outer side of one set of guide frames 401 below the abutment block 409. A movable guide rail 410 is provided, and a locking block 411 is slidably connected inside the movable guide rail 410. The top of the locking block 411 abuts against the bottom of the abutment block 409. A linkage rope 412 is fixedly connected between the locking block 411 and the support plate 403. A guide rope wheel 413 is rotatably connected at the connection between the front end of the movable guide rail 410 and the linkage rope 412. The crushing block 402 is fixed to the top of the guide frame 401 by the slider 408 of the stabilizing plate 406. The abutment block 409 abuts tightly against the top of the locking block 411 to form a mechanical lock. The rear end of the support plate 403 is unloaded. With the snails in the raised position, the locking block 411 is stationary within the moving guide rail 410. The golden apple snails enter the snail collector 1 through the one-way movable curtain door 2. An attractant is placed in the trapping trough 405, causing the snails to gather at the trapping trough 405 of the support plate 403. When the total weight of the snails exceeds a preset value, the rear end of the support plate 403 sinks due to gravity. This sinking pulls the linkage rope 412, which, after being turned by the guide wheel 413, pulls the locking block 411 to slide horizontally along the moving guide rail 410. The locking block 411 disengages from the bottom contact surface of the abutment block 409, releasing the sliding contact. Constrained by block 408, after crushing block 402 loses its lock, slider 408 falls vertically along the slide groove 407 of guide frame 401. Crushing block 402 is precisely confined within the slide of guide frame 401. Its only movement trajectory is a linear reciprocating motion in the vertical direction, that is, crushing vertically downwards and resetting vertically upwards. Crushing block 402 can easily crush the snail shell and squeeze the snail meat, achieving preliminary physical "harmless treatment". The treated golden apple snail remains sink into the water through the hollow bottom of snail collector 1 to provide nutrients to the surrounding aquatic plants.

[0027] Then, the crushing block 402 is made of concrete or stainless steel and covered with a biodegradable material. Multiple sets of conical protrusions 414 are fixedly connected to the bottom of the crushing block 402. The crushing block 402 is a precast concrete block or stainless steel plate to provide sufficient downward pressure. The outside can be wrapped with a biodegradable bio-friendly material to reduce potential environmental impact. The multiple sets of conical protrusions 414 can form multiple stress concentration points when the crushing block 402 is pressed down, ensuring that the hard shell of the golden apple snail can be effectively broken, rather than simply pushed away.

[0028] Furthermore, both the front and rear ends of the top of the crushing block 402 are fixedly connected with through rods 415. Multiple sets of counterweights 416 are sleeved on the outer side of both sets of through rods 415. The top ends of both sets of through rods 415 are threaded with positioning sleeves 417. A reset lifting rod 418 is fixedly connected to the center of the top of the crushing block 402. The weight of the crushing block 402 can be adjusted by adding or removing counterweights 416 to meet the processing needs of different sizes and quantities of golden apple snails. After the device completes one automatic processing cycle, the crushing block 402 will stay at the bottom of the snail collector 1. The operator needs to manually pull it back to the top through the reset lifting rod 418 on the top of the crushing block 402. Then, the locking block 411 is pressed against the bottom of the abutment block 409 again, thereby fixing the crushing block 402 and completing the reset, entering the next "standby-trigger-processing" cycle.

[0029] Both sets of stabilizing plates 406 are rotatably connected to rollers 419, and both sets of rollers 419 are in contact with the inner sidewall of the guide frame 401. After the crushed block 402 is unlocked, the stabilizing plate 406 falls vertically along the slide groove 407 of the guide frame 401. The rollers 419 reduce friction and improve the downward pressure stability of the crushed block 402.

[0030] Furthermore, the multiple side walls of the snail collector 1 are provided with pores, and the bottom of the snail collector 1 is hollowed out. The snail collector 1 is woven in an interlaced manner, and the pores formed are about 1-2cm in size. This ensures both water permeability and air permeability inside the device, making it easy to observe the internal conditions, and effectively prevents larger golden apple snails from escaping. The bottom of the snail collector 1 is hollowed out, and the pores formed are slightly larger, at 3-4cm, which facilitates the sinking of the processed golden apple snail fragments.

[0031] Secondly, the one-way movable curtain 2 is composed of multiple sets of flexible sheets 201, all of which are made of biodegradable plastic sheets. The tops of the multiple sets of flexible sheets 201 are hinged to the snail collector 1, and the bottoms of the multiple sets of flexible sheets 201 are in contact with the inner side of the snail collector 1. When the golden apple snail crawls from the outside into the snail collector 1, it can easily push open the one-way movable curtain 2 composed of multiple sets of flexible sheets 201 to enter the snail collector 1. When it tries to return from the inside, the multiple sets of flexible sheets 201 will naturally droop and close due to their own weight and tilt angle, forming an insurmountable barrier, thus effectively trapping it. The biodegradable plastic sheets achieve zero pollution, and the hinged structure ensures adaptability and prevents the captured snail from escaping.

[0032] Finally, the tops of the multiple sets of adjustable support legs 3 are hinged to the screw collector 1 via connectors 301, and the bottoms of the multiple sets of adjustable support legs 3 are threaded with adjustable support cone sleeves 302. The length of the adjustable support cone sleeves 302 is adjusted to match the 0-15° shore slope. The hinged connectors 301 allow non-planar contact, ensuring that the device remains horizontally stable in complex terrain and that the gravity crushing module 4 can work vertically.

[0033] In this embodiment, the specific implementation scenario is as follows: A lakeshore area where golden apple snails are frequently active is selected. The length of the threaded adjustable support cone sleeve 302, a terrain-adaptive structure, is adjusted according to the actual slope to keep the snail collector 1 horizontal and stable. Then, the operator manually pulls the crushing block 402 back to its top using the reset lever 418 at the top, causing the locking block 411 to press against the bottom of the abutment block 409 again. The abutment block 409 and the top of the locking block 411 are tightly abutted together, forming a mechanical lock, thereby preventing the crushing block 402 from entering the water. When the system is in a fixed standby state, the rear end of the support plate 403 is raised due to the lack of load. Golden apple snails enter the snail collector 1 through the one-way movable curtain door 2. An attractant is placed in the trapping trough 405, causing the snails to gather at the trapping trough 405 of the support plate 403. When the total weight of the snails exceeds a preset value, the rear end of the support plate 403 sinks due to gravity. This sinking pulls the linkage rope 412, which, after being turned by the guide wheel 413, causes the traction locking block 411 to slide horizontally along the moving guide rail 410, disengaging from the abutment block 409. At the bottom contact surface, the constraint on slider 408 is released. After crushing block 402 is unlocked, slider 408 falls vertically along the groove 407 of guide frame 401. Crushing block 402 can easily crush the snail shell and squeeze the snail meat, achieving preliminary physical "harmless treatment". After the device completes automatic processing, it is in a standby state. If the manager finds that the device has been triggered during inspection, he can operate the reset lever 418 to pull crushing block 402 back to the top and lock it, so that the device returns to the standby state. The processed golden apple snails The remains sink into the water through the hollow bottom of the snail collector 1, providing nutrients to the surrounding aquatic plants and being treated as organic waste. Managers can also assist in cleaning up the golden apple snail remains inside the collector. The entire operation process is simple and convenient. This utility model is made of natural and environmentally friendly materials and has an ingenious structural design. It can not only efficiently trap golden apple snails and prevent them from escaping, but also perform preliminary harmless treatment on the captured snails. At the same time, it can be stably deployed along the shores of lakes with various slopes, solving the problems of secondary pollution, high cost, and poor terrain adaptability of existing technologies.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
