DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0023] Please refer to Figures 1-4 The present application provides a technical solution:

[0024] Please refer to Figures 1-4 As shown in the figure, a device for monitoring the population number of golden apple snails, comprising a trapping cage 1, a bait placing tank 2 arranged on both sides of the trapping cage 1; a slot 3 formed on the trapping cage 1, the slot 3 being in the shape of a Chinese character "Kuo"; a clamping rod 4 fixedly installed on the slot 3; a clamping block 5 fixedly installed on the outer wall of the trapping cage 1, the inner wall of the clamping block 5 being provided with a reset member 6; the bait placing tank 2, the clamping block 5 and the reset member 6 all being in the shape of an arc, the inner arc wall of the reset member 6 abutting against the clamping rod 4.

[0025] In the novel device for monitoring the population number of golden apple snails, the bait placing tank 2 is installed on both sides of the trapping cage 1. When the bait placing tank 2 needs to be installed, it is aligned with the slot 3 formed on the trapping cage 1, the slot 3 being in the shape of a Chinese character "Kuo", and the clamping rod 4 is fixedly installed on the slot 3. During the installation of the bait placing tank 2, the peripheral structure of the bait placing tank 2 will push the reset member 6. Since the reset member 6 is installed on the inner wall of the clamping block 5 and both of them are in the shape of an arc, when subjected to force, the clamping block 5 and the reset member 6 will deform. When the bait placing tank 2 continues to advance until the clamping block 5 goes beyond the clamping rod 4, the clamping block 5 and the reset member 6 will restore to the original state under the action of their own elastic force, and the inner arc wall thereof abuts against the clamping rod 4 again. At this time, the installation and fixation of the bait placing tank 2 are completed. When disassembling, the clamping block 5 and the reset member 6 are pushed in the reverse direction with force, so that the clamping block 5 and the reset member 6 deform again and go beyond the clamping rod 4. Thus, the bait placing tank 2 can be taken out of the slot 3.

[0026] Different from the complex operation of tightening or loosening by using a wrench and other tools in the conventional way of adopting a bolt and a nut, the device only needs to perform a simple clamping operation by aligning the bait placing tank 2 with the slot 3, without the need of using additional tools, thereby greatly reducing the installation steps and saving the time and effort of the operating personnel.

[0027] In the case of monitoring the population of apple snails in a large area, a large number of traps 1 need to be carried and the bait needs to be replaced frequently. The convenient installation method greatly shortens the installation time of the bait placing tank 2 of each trap 1.

[0028] Referring to Figure 4 , the inner wall of the slot 3 is provided with an elastic member 7 in the shape of a V, and the slot 3 is slidingly connected with an abutting block 8, which is arranged above the elastic member 7 and below the clamping block 5.

[0029] The elastic member 7 is in the shape of a V. After the bait placing tank 2 is installed in place, the elastic member 7 can provide a certain elastic pressure, so that the abutment between the clamping block 5 and the clamping rod 4 is more closely, preventing the clamping block 5 from accidentally loosening or detaching from the clamping rod 4, thereby further enhancing the fixing effect of the bait placing tank 2 and ensuring its stability during monitoring, not easy to shake or fall due to external factors such as water flow, wind blowing, etc.

[0030] Referring to Figure 4 , the clamping block 5, the reset member 6, and the elastic member 7 are all made of spring steel.

[0031] Spring steel has high strength and can withstand large external forces without permanent deformation or damage. When the clamping block 5 cooperates with the clamping rod 4 to fix the bait placing tank 2, it will bear a certain tension and pressure. The clamping block 5 made of spring steel can withstand these forces, ensuring the reliability of the connection. In the field environment, even if subjected to external forces such as water flow impact, animal collision, etc., the clamping block 5, the reset member 6, and the elastic member 7 can maintain structural integrity, ensuring normal operation of the device.

[0032] Referring to Figure 3 , the trap 1 is provided with an inlet pipe 9, which is inclinedly arranged. The inlet pipe 9 is provided with a connecting pipe 10 at one end close to the trap 1. The connecting pipe 10 is in the shape of a funnel, and the two openings of the connecting pipe 10 are wide and narrow, respectively.

[0033] The inlet pipe 9 is arranged in an inclined manner, and the connecting pipe 10 is in the shape of a funnel, with the wide opening facing outward and the narrow opening connected to the inside of the trap 1. This structure can take advantage of the climbing habit of apple snails to guide them more easily into the connecting pipe 10 from the wide opening, and then into the trap 1 along the inlet pipe 9, improving the trapping efficiency.

[0034] The funnel-shaped connecting pipe 10 makes it difficult for apple snails to find their way back after entering, and the design of the narrow opening makes it difficult for apple snails to escape from the trap 1 through the connecting pipe 10, increasing the probability of apple snails being trapped in the trap 1, thereby more accurately monitoring the population of apple snails.

[0035] The arrangement of the inlet pipe 9 and the connecting pipe 10 can protect the bait in the bait placing tank 2 in the trap cage 1 to a certain extent, reduce the erosion and dilution of the bait by external factors such as rainwater and water flow, and enable the bait to maintain effectiveness for a longer period of time to attract more golden apple snails.

[0036] Referring to Figure 3 The connecting pipe 10 is hinged with a mesh door 11, and a torsion spring 12 is arranged between the connecting pipe 10 and the mesh door 11.

[0037] The torsion spring 12 enables the mesh door 11 to remain closed under normal circumstances, and when the golden apple snail enters from the wide mouth of the connecting pipe 10, it can push open the mesh door 11 to enter the trap cage 1, and after entering, the mesh door 11 will automatically close due to the torsion of the torsion spring 12, preventing the golden apple snail from returning from the trap cage 1 to the connecting pipe 10, achieving one-way traffic and effectively improving the trapping effect and more accurately monitoring the population size of the golden apple snail.

[0038] Referring to Figures 1-2 One side of the bait placing tank 2 is threadedly connected with a sealing cover 13, and one side of the sealing cover 13 is mounted with a handle.

[0039] The design of the handle can increase the convenience of operation, and also prevent the sealing cover 13 from being opened by mistake to a certain extent. Only by consciously turning the handle can the sealing cover 13 be opened, avoiding the loosening or opening of the sealing cover 13 due to accidental collision during transportation, installation or field use, ensuring the sealing of the bait placing tank 2 and the effectiveness of the bait.

[0040] Referring to Figure 3 The top of the narrow mouth of the connecting pipe 10 is provided with an image recognition module 14.

[0041] The image recognition module 14 is externally provided with waterproofing.

[0042] The image recognition module 14 can take real-time images of the golden apple snails entering the trap cage 1, without the need for frequent manual checking of the trapping situation, and can obtain information about the entry of the golden apple snails in a timely manner, facilitating researchers to understand the dynamic changes in the population size of the golden apple snails at any time.

[0043] Through image recognition technology, the number of golden apple snails entering the trap cage 1 can be accurately counted, avoiding errors that may occur in manual counting and improving the accuracy and reliability of the monitoring data.

[0044] The captured images can be saved and analyzed as data, which helps researchers to understand the activity patterns and entry time distribution of the golden apple snails, and provides more abundant data support for further research on the trend of changes in the population size of the golden apple snails.

[0045] The image recognition module 14 is installed at the top of the narrow opening of the connecting pipe 10, belongs to a non-contact monitoring mode, does not interfere with the entry of the golden apple snail, does not affect the environment and the bait effect in the trap cage 1, and can more truly reflect the natural behavior and population quantity of the golden apple snail.

[0046] Referring to Figure 1 The top of the trap cage 1 is provided with a plurality of ground inserts, and the ground inserts are provided in a shape of being wide at the top and narrow at the bottom.

[0047] The shape of being wide at the top and narrow at the bottom makes the ground inserts easier to be inserted into the ground and provides more stable support after being inserted. The wide part above the ground can increase the contact area with the ground, disperse the weight of the trap cage 1, reduce the possibility of shaking or toppling of the trap cage 1 caused by external forces such as wind blowing and water flow impact, and ensure that the device maintains a stable position during the monitoring process, so as to more accurately monitor the population quantity of the golden apple snail.

[0048] The above only describes the embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
