Description

Technical Field

[0001] This invention relates to the field of termite control technology, and in particular to a storage carrier for a termite bait for dams. Background Technology

[0002] As a key component of water conservancy systems for flood control, irrigation, and water supply, dikes play a crucial role in safeguarding people's lives and property and promoting economic and social development. However, tiny termites can pose a significant threat to dikes, becoming an "invisible killer" of dike safety.

[0003] Termite tunnels and nests not only damage the structural integrity of dikes but also reduce their strength and stability. As termite colonies continue to multiply and grow, the damage to dikes intensifies. When water levels rise during the flood season, water seeps into the dike interior along the termite tunnels, causing problems such as piping, seepage, and wet slopes. Piping continuously erodes the soil material inside the dike, causing the cavities to gradually enlarge, resulting in significant soil loss and ultimately leading to dike subsidence or collapse.

[0004] To control termites, high-density baiting carriers are usually set up, which attract and disinfect termites through the internal attractant. However, the current carriers have a short disinfecting cycle of attractant, making it difficult to disinfect termites continuously for a long time. In addition, the consumption process of internal consumables cannot be known, which is not conducive to timely replenishment of consumables, resulting in unsatisfactory results. Summary of the Invention

[0005] The purpose of this invention is to solve the above problems by providing a storage carrier for termite bait on dams that can preset the crawling and gnawing trajectory of termites, extend the termite attraction and extermination cycle, and accurately determine the remaining length of the internal bait sticks for timely replenishment.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a storage carrier for termite attractant for dams, comprising a cylinder, a top cover installed on the top of the cylinder, and a cone integrally formed at the bottom. An attraction hole is provided on the bottom circumference of the cylinder, and a slag discharge hole is provided on the circumference of the cone. An attraction carrier is disposed inside the cylinder, the attraction carrier comprising multiple limiting cylinders and attraction sticks, each limiting cylinder and attraction stick corresponding to the other. The attraction stick is vertically arranged and has a wax layer on its outer circumference. Termite entry and exit holes are provided on the bottom circumference of the limiting cylinder. After termites enter the limiting cylinder, they gnaw on the bottom surface of the attraction stick, causing the bottom of the attraction stick to be gnawed and suspended, eventually falling naturally.

[0007] Preferably, the inner wall of the cylinder is uniformly fixed with a plurality of claws, the claws being in the shape of a 3 / 4 ring, one end of the claw being fixed to the inner wall of the cylinder, and the other end engaging with the limiting cylinder.

[0008] Preferably, the bottom of the limiting cylinder is provided with a movable bottom cover, which is hinged to the limiting cylinder by a hinge buckle. After the movable bottom cover is rotated downward and opened, the wood chips and termite corpses enter the cone.

[0009] Preferably, a lifting ring is provided between the cylinder and the cone, and a base is concentrically provided inside the lifting ring. The lifting ring and the base are fixed together by a connecting rod. Multiple tension springs are provided on the lifting ring, and the top of the tension springs is fixedly connected to the movable bottom cover. When the lifting ring descends, the movable bottom cover is opened by pulling the tension springs.

[0010] Preferably, a lifting column is vertically fixed on the surface of the chassis, and a horizontally arranged support plate is provided inside the cylinder. The lifting column extends upward through the support plate, and an integral pressure plate is provided at the extended end of the lifting column. The surface of the pressure plate is provided with a groove, and a rotatable cam is provided in the groove. A spring is provided between the bottom surface of the pressure plate and the support plate. After the cam rotates, the lifting column drives the lifting ring to move up and down.

[0011] Preferably, the circumference of the support plate is further provided with a limiting rod extending horizontally outward, and the limiting rod engages with a slot on the inner wall of the cylinder.

[0012] Preferably, a height sensor is fixed to the top of the lure stick. The height sensor sends height position information to the outside world through a signal processing and control module, and the remaining length of the lure stick is determined by the height information of the height sensor.

[0013] Preferably, the inner top wall of the top cover is provided with connecting cylinders that correspond one-to-one with the guiding wooden sticks, and a rotating shaft runs horizontally through the connecting cylinder. The height sensor is wound around the rotating shaft by a traction rope.

[0014] Preferably, the trajectory of the guiding hole is the same as the height of the inlet and outlet hole, wherein the inner diameter of the guiding hole is larger than the inner diameter of the inlet and outlet hole.

[0015] Preferably, the attracting wooden stick is any one or a combination of pine, fir, poplar, willow and birch.

[0016] This invention discloses a storage carrier for termite bait on dams, comprising a cylindrical body with a top cover and an integrally formed cone at the bottom. The bottom circumference of the cylindrical body has an attraction hole, and the circumference of the cone has a discharge hole. An attraction carrier is placed inside the cylindrical body, comprising multiple limiting cylinders and attraction sticks, with each limiting cylinder and attraction stick corresponding to the other. The attraction sticks are vertically positioned and have a wax layer on their outer circumference. The bottom circumference of each limiting cylinder has a termite entry / exit hole. After termites enter the limiting cylinder, they gnaw on the bottom surface of the attraction sticks, causing the sticks to hang suspended and fall naturally. Compared with existing technologies, this storage carrier for termite bait on dams has the advantages of being able to preset the termite crawling and gnawing trajectory, extending the termite attraction and extermination cycle, and accurately determining the remaining length of the attraction sticks for timely replenishment.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0028] Please refer to Figure 1 A storage carrier for termite bait on dams includes a cylinder 1. A top cover 2 is installed on the top of the cylinder 1, which is detachably connected to the cylinder 1 via an internal thread 21, facilitating the replenishment of bait material inside the cylinder 1. A cone 3 is integrally formed at the bottom of the cylinder 1, which not only allows for easy penetration into the soil but also collects dead termites and the bait material consumed inside. Attraction holes 4 are provided around the bottom circumference of the cylinder 1. A slag discharge hole 5 is provided around the circumference, and active termites in the soil enter the cylinder 1 through the attraction hole 4; an attraction carrier 6 is provided inside the cylinder 1, and the attraction carrier 6 includes multiple limiting cylinders 61 and attraction sticks 7. The limiting cylinders 61 and attraction sticks 7 correspond one-to-one, that is, the attraction sticks 7 are inserted into the corresponding limiting cylinders 61. The attraction sticks 7 are vertically arranged and have a wax layer on the outer circumference and top surface. The bottom circumference of the limiting cylinder 61 is provided with termite entry and exit holes 63.

[0029] Because the outer circumference and top surface of the attractant stick 7 are provided with a wax layer, the wax layer can isolate the inside and outside of the attractant stick 7, thus preventing termites from directly gnawing on the outer circumference of the attractant stick 7, which can greatly extend the termite attraction and extermination cycle. That is, termites enter the cylinder 1 through the attraction hole 4, and then enter the limiting cylinder 63 through the inlet and outlet hole 63. Since the outer circumference and top surface of the attraction stick 7 are provided with a wax layer, the termites are forced to feed only from the bottom of the attraction stick 7. After feeding, the attraction stick 7 exerts its medicinal effect to disinfect the termites. The termites and the wood chips that fall off after being disinfected will accumulate in the limiting cylinder 61. After being eaten, the length of the attraction stick will continuously shorten, and the shortened attraction stick will fall downwards by its own weight.

[0030] In this embodiment, a plurality of claws 62 are uniformly fixed on the inner wall of the cylinder 1. The claws 62 are in the shape of a 3 / 4 ring. One end of the claw 62 is fixed to the inner wall of the cylinder 1, and the other end engages with the limiting cylinder 61, thereby supporting and limiting the entire internal entrapment carrier.

[0031] When the attractant stick 7 is gnawed, it will produce wood chips and a large number of termite corpses. In order to prevent the wood chips and termite corpses from accumulating in the limiting cylinder 61, a movable bottom cover 64 is provided at the bottom of the limiting cylinder 61. The movable bottom cover 64 is hinged to the limiting cylinder 61 by a hinge buckle 65. After the movable bottom cover 64 is rotated downwards and opened, the wood chips and termite corpses enter the cone 3. When the whole is removed, shaking the cylinder 1 can make the wood chips and termite corpses in the cone 3 be discharged from the slag discharge hole 5.

[0032] To enable the movable bottom cover 64 to open or close automatically, a lifting ring 8 is provided between the cylinder 1 and the cone 3. A base 93 is concentrically provided inside the lifting ring 8. The lifting ring 8 and the base 93 are fixed together by a connecting rod 82. Multiple tension springs 66 are provided on the lifting ring 8. The top of the tension springs 66 is fixedly connected to the movable bottom cover 64. When the lifting ring 8 descends, the tension springs 66 pull the movable bottom cover 64 to open.

[0033] In other words, the descent of the lifting ring 8 can pull the movable bottom cover 64 downward through the tension spring 66. After the movable bottom cover 64 flips downward, the wood chips and other debris inside will slide into the cone 3, which plays the role of removing debris and at the same time provides a space for dense termites inside to gnaw.

[0034] Specifically, a lifting column 92 is vertically fixed to the surface of the chassis 81, and a horizontally arranged support plate 9 is provided inside the cylinder 1. The lifting column 92 extends upward through the support plate 9, and an integral pressure plate 93 is provided at the extended end of the lifting column 92. The surface of the pressure plate 93 is provided with a groove 931, and a rotatable cam 932 is provided in the groove 931. A spring 94 is provided between the bottom surface of the pressure plate 93 and the support plate 9. After the cam 932 rotates, the lifting column 92 drives the lifting ring 8 to move up and down.

[0035] In this embodiment, the cam 932 is driven to rotate by a servo motor. A control box is installed on the support plate 9. The control box contains a rechargeable power supply, a microcontroller (such as STM32), a timer, etc. Before use, the speed and drive cycle of the servo motor are set so as to meet the periodic opening and closing of the movable bottom cover 64.

[0036] When the drive cycle of the servo motor is set to 4 hours and the number of revolutions is 2, that is, the servo motor rotates 2 times every 4 hours, the movable bottom cover 64 will open and close twice every 4 hours. After each time, the movable bottom cover 64 will be closed by the spring 94 and the tension spring 66 to prevent the termites inside from falling in and being unable to gnaw on the wooden stick.

[0037] As a preferred embodiment, the circumference of the support plate 9 is also provided with a limiting support rod 91 extending horizontally outward. The limiting support rod 91 cooperates with the slot 11 on the inner wall of the cylinder 1. The support plate 9 can provide a driving platform for the servo motor, control box, lifting column 92, etc., and meet the requirements for smooth opening and closing of the movable bottom cover 64.

[0038] The termite bait carrier for this dam is buried in the soil during use, so the consumption of the bait sticks 7 cannot be observed after burial. Once the bait sticks 7 are exhausted, termite extermination cannot be achieved. In order to obtain the remaining status of the bait sticks 7 in real time and to continuously exterminate termites, a height sensor 71 is fixed on the top of the bait sticks 7. The height sensor 71 sends height position information to the outside world through a signal processing and control module, and the remaining length of the bait sticks 7 is determined by the height information of the height sensor 71.

[0039] The height sensor 71 is equipped with a matching control block. If power is required, it can be provided through the control box. When using it, the height threshold is preset first (where the threshold is ≤ the length of the lure stick 7). At the highest value, the lure stick 7 is a complete stick, and at this time the height sensor 71 is located at the highest point; At the lowest value, the lure stick 7 is about to be completely eaten or has already been eaten, and at this time the height sensor 71 is close to or about to be close to the movable bottom cover 64. As the bottom of the lure stick 7 is continuously gnawed, its length will shorten. The shortened lure stick 7 will fall under its own weight. At this time, the height sensor 71 at the top of the lure stick 7 will also fall. After falling, the real-time height value and the maximum value will generate a height difference (threshold). When the height difference of the threshold is close to or equal to the length of the lure stick 7, the height sensor 71 will detect that the threshold has been exceeded and trigger the transmission of an alarm signal to the outside world, reminding the supervisor that the lure stick 7 has been completely gnawed or is about to be completely gnawed. At this time, the staff can refill the lure stick 7.

[0040] The principle is as follows: when the height sensor 71 is triggered, the alarm signal is output in a standardized way and directly connected to the outside, that is, the alarm is output through the relay contact, which can be directly connected to the buzzer, indicator light, etc.; then the alarm data is sent to the microcontroller via Ethernet; after receiving the alarm information, the external staff can know that the wooden stick in a certain place has been eaten and can replace it.

[0041] As a preferred option, a positioning module can also be integrated into one side of the height sensor 71, and multiple height sensors 71 can be numbered so that staff can know the precise location when an alarm is triggered, thereby achieving the effect of quickly filling wooden sticks.

[0042] It is understandable that the height sensor 71 can be fixed by screws, glue or other means, as long as the height sensor 71 is fixed to the lure stick 7.

[0043] As a preferred embodiment, the inner top wall of the top cover 2 is provided with connecting cylinders 22 corresponding one-to-one with the lure sticks 7. A rotating shaft 23 runs horizontally through the connecting cylinder 22. The height sensor 71 is wound around the rotating shaft 23 by a traction rope 72. In the initial state, the traction rope 72 is completely wrapped around the rotating shaft 23. As time goes by, the bottom of the lure sticks 7 will be continuously gnawed. At this time, the lure sticks 7 pull the traction rope 23 down, thereby causing the height sensor 71 to change its data.

[0044] Based on the above embodiments, the trajectory of the attracting hole 4 is the same as the height of the inlet / outlet hole 63, that is, the height of the attracting hole 4 is the same as the height of the inlet / outlet hole 63, and the annular trajectory of the attracting hole 4 covers the inlet / outlet hole 63. This facilitates the termites to directly enter the limiting cylinder 61 through the inlet / outlet hole 63 after entering the cylinder 1, shortening the termite crawling path. In addition, the inner diameter of the attracting hole 4 is larger than the inner diameter of the inlet / outlet hole 63, which satisfies the requirement of a large influx of termites into the cylinder 1.

[0045] Based on the above embodiments, the attracting wooden stick is any one or more combinations of pine, fir, poplar, willow, and birch.

[0046] Understandably, the bait sticks are soaked in a chemical solution before installation to achieve the effect of attracting and eliminating pests.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
