Description

Technical Field

[0001] This invention relates to the field of termite trapping technology, and in particular to a pre-embedded termite trapping device for water conservancy dams. Background Technology

[0002] Termites are social insects that live in colonies. Based on their habitat, they can be divided into wood-dwelling termites, soil-dwelling termites, and amphibious termites. Soil-dwelling termites nest and live in the soil; they cannot survive normally without soil, which is their only habitat and place. Soil-dwelling termites can build large nests in the earthen embankments of rivers, reservoirs, and other waterways, constructing tunnels that penetrate the embankments over distances of tens of meters, posing a significant threat to the operational safety of the embankments.

[0003] Currently, the main methods for termite control on dikes include nest excavation, grouting, and baiting. Nest excavation involves manually digging through surface termite activity traces until the main nest is found. This is an ancient and primitive method, requiring significant manpower, damaging the dike, and its speed cannot keep up with the natural reproduction rate of termites, making it impossible to completely eradicate all termite nests on the dike. Grouting involves creating holes in the dike and then mechanically pressurizing and injecting medicated mud into these holes, using the termite tunnel system to deliver the medicated mud into the nest. Grouting is a massive undertaking and can be somewhat indiscriminate. Baiting involves locating traces of soil-dwelling termite activity on the dike, placing bait where the termites feed. The termites' behaviors of feeding each other, cannibalizing carcasses, and raising larvae transmit the active ingredients of the bait to the entire colony, causing even those that haven't come into contact with the bait to die, thus killing the entire termite colony. Baiting has significant advantages such as being able to kill the entire termite colony, being minimally destructive, requiring small amounts, and being environmentally friendly and safe. Baiting is currently recognized as the most efficient and environmentally friendly method for controlling termites on dikes.

[0004] Currently used termite-killing devices mostly involve spraying termite-killing agents into the device beforehand, or spraying agents into the bait box to kill termites. However, the bait box needs to be buried underground. When it rains, rainwater enters the bait box, causing the agent to be corroded and rendered ineffective, affecting the use of the bait box. In addition, the powder is easily affected by moisture underground and loses its activity, or the powder is wasted during use, requiring staff to frequently check and replenish the powder. This not only increases labor costs but also reduces the efficiency of termite control.

[0005] Therefore, this application proposes a pre-embedded termite trapping device that prevents the pesticide powder from being eroded by rainwater and facilitates automatic replenishment of the pesticide powder. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a pre-embedded termite trapping device for water conservancy dams.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A termite trapping device for a water conservancy dam includes a pre-buried pipe and multiple trays for placing bait inside the pre-buried pipe. The multiple trays are arranged in layers inside the pre-buried pipe. The pre-buried pipe is equipped with a feeding component for replenishing pesticide powder. The surface of the pre-buried pipe has multiple channels for termites to enter and exit. The multiple channels are located near the lower end of the pre-buried pipe and are arranged in layers.

[0008] In some embodiments, the feeding assembly includes a feed bottle that slides inside a pre-embedded tube and a plurality of connecting tubes fixed to the bottom of the feed bottle.

[0009] In some embodiments, multiple trays are fixed to the surface of a connecting pipe, the multiple connecting pipes are of different lengths, and the lower ends of the multiple connecting pipes are respectively located above the multiple trays.

[0010] In some embodiments, the material bottle and multiple trays slide towards the upper end of the pre-embedded pipe via a lifting assembly, and a retaining ring is fixed on the surface of the pre-embedded pipe, the retaining ring being located above the channel.

[0011] In some embodiments, the tray surface is provided with a dredging component to prevent the attractant from clogging the connecting pipes. The dredging component includes a plurality of dredging rods that slide vertically inside a plurality of connecting pipes. The upper end of the dredging rod is located inside the container, and the lower end of the dredging rod is located below the bottom tray and is fixedly connected by a connecting plate.

[0012] In some embodiments, the bottom surface of the lowest tray is fixed with a base plate by a plurality of connecting rods, and an electric push rod is fixed on the upper surface of the base plate for driving the connecting plate and the unclogging rod to slide up and down. The surface of the unclogging rod is provided with a plurality of protruding balls.

[0013] In some embodiments, the surfaces of the plurality of trays are provided with a dispersion component for dispersing the attractant. The dispersion component includes an air tube fixed at the center of the tray and a plurality of air nozzles opened on the surface of the air tube, the plurality of air nozzles respectively facing the lower end of a plurality of connecting tubes.

[0014] In some embodiments, the upper end of the air tube is located inside the bottle, and the upper end of the air tube is connected to an air pump via a connector. Both the air pump and the connector are located on the surface of the bottle cap.

[0015] In some embodiments, a rain sensor is fixed to the upper surface of the retaining ring.

[0016] In some embodiments, the lower end of the embedded pipe is an open structure, and a support assembly is provided at the lower end of the embedded pipe. The support assembly includes a support ring fixed to the lower end of the embedded pipe by a plurality of support rods, and the lower end of the base plate is tapered.

[0017] Compared with the prior art, the present invention provides a termite trapping device pre-embedded in water conservancy dams, which has the following beneficial effects.

[0018] 1. The present invention, by setting up a feeding component, gradually replenishes the bait in the feed bottle to multiple trays through a connecting pipe, thereby ensuring that the bait in the trays is always sufficient, so that the surface of the termites is covered with enough effective bait.

[0019] 2. In this invention, by setting up a dredging component, the electric push rod drives the base plate and multiple dredging rods to move up and down. Under the action of the convex ball, the dredging rods drive the attractant inside the bottle to flow downward through the connecting pipe, so as to replenish the material smoothly and avoid the attractant from being blocked inside the connecting pipe and affecting the replenishment.

[0020] 3. In this invention, by setting up a dispersion component, the air pump is activated during the up-and-down movement of the unblocking rod, which introduces air into the air pipe and sprays it out through multiple air nozzles, thereby blowing away the sliding attractant and causing it to float above the tray, thus preventing the attractant from accumulating.

[0021] 4. In this invention, by setting up a stirring sleeve, during the up-and-down sliding of the unblocking rod, the connecting frame drives the stirring sleeve to slide up and down on the surface of the gas pipe. Under the action of the spiral guide rail, the stirring sleeve rotates while sliding up and down, thereby stirring the attractant inside the bottle, allowing it to fall smoothly downwards and slide down to the tray surface through the connecting pipe.

[0022] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Reference Figure 1-9 A termite trapping device for a water conservancy dam includes a pre-buried pipe 1 and multiple trays 2 for placing bait inside the pre-buried pipe 1. The multiple trays 2 are arranged in layers inside the pre-buried pipe 1. A feeding component 3 for replenishing pesticide powder is provided inside the pre-buried pipe 1. The feeding component 3 slides vertically inside the pre-buried pipe 1 via a lifting component 304. The surface of the pre-embedded pipe 1 has multiple channels 101 for termites to enter and exit. The multiple channels 101 are close to the lower end of the pre-embedded pipe 1 and are arranged in layers. The upper end of the pre-embedded pipe 1 is threaded with a top cover 102. The side of the pre-embedded pipe 1 has an opening. The side of the pre-embedded pipe 1 is hinged with a cover plate 103 for closing the opening. The feeding assembly 3 includes a material bottle 301 that slides inside the pre-embedded pipe 1 and multiple connecting pipes 302 fixed to the bottom of the material bottle 301. Multiple trays 2 are fixed to the surface of the connecting pipes 302. The multiple connecting pipes 302 are of different lengths and the lower ends of the multiple connecting pipes 302 are respectively located above the multiple trays 2. A bottle cap 303 is threadedly connected to the top of the material bottle 301.

[0035] Understandably, by setting up pre-buried pipe 1, with its lower end buried underground in the dam ground, placing wood bait on the surface of tray 2, and adding termite bait (termite bait typically refers to a powder containing low-dose, chronically effective ingredients; after termites come into contact with the bait, they carry it back to their nest and spread it within the colony through feeding and cleaning behaviors, ultimately leading to the death of the queen, king, and larvae, thus achieving whole-nest control) through multiple connecting pipes 302, the bait is distributed onto the surfaces of multiple trays 2. When termites enter the surface of tray 2 through channel 101 and gnaw on the wood, they become contaminated with the bait. After returning to the nest, they come into contact with other termites, causing the termites in the nest to also become contaminated with the bait and die, thus achieving the purpose of exterminating termites. Since the bait will gradually deplete, a replenishment component 3 is set up to gradually replenish the bait in the bottle 301 to multiple trays 2 through the connecting pipe 302, thereby ensuring that the bait in the trays 2 is always sufficient, so that the surface of the termites is contaminated with enough effective bait. By setting the top cover 102, it is easy to open the upper end of the pre-embedded pipe 1, so that the bait can be added into the material bottle 301. By setting the opening and cover plate 103 on the side of the pre-embedded pipe 1, it is easy to add wood bait to the surface of multiple trays 2, while cleaning up residual wood chips and ineffective bait.

[0036] Specifically, the material bottle 301 and multiple trays 2 slide towards the upper end of the pre-embedded pipe 1 via the lifting assembly 304. The lifting assembly 304 includes two rotating wheels that rotate inside the pre-embedded pipe 1. The two rotating wheels are connected by a transmission rope. The material bottle 301 is fixed to the surface of the transmission rope. A drive motor for driving one of the rotating wheels is fixed to the surface of the pre-embedded pipe 1. A retaining ring 7 is fixed to the surface of the pre-embedded pipe 1. The retaining ring 7 is located above the channel 101. A rain sensor 8 is fixed to the upper surface of the retaining ring 7.

[0037] Understandably, by setting up a rain sensor 8, when it rains, the rain sensor 8 detects rainwater and sends a signal to drive the motor, which drives the rotating wheel to rotate. Under the action of the transmission rope, the material bottle 301 and multiple trays 2 can be pulled upwards to the upper end of the pre-buried pipe 1, preventing rainwater from entering the surface of the tray 2 through the channel 101 and damaging the attractant. By setting up a retaining ring 7, the part of the pre-buried pipe 1 located below the retaining ring 7 is buried in the ground, which makes it easier to control the pre-buried depth. At the same time, the retaining ring 7 can temporarily block rainwater, giving the material bottle 301 and tray 2 time to move upwards, preventing rainwater from quickly seeping into the channel 101 through the gap between the pre-buried pipe 1 and the ground during a sudden heavy rain.

[0038] Specifically, the surface of tray 2 is provided with a dredging component 4 to prevent the attractant from clogging the connecting pipe 302. The dredging component 4 includes multiple dredging rods 401 that slide vertically inside multiple connecting pipes 302. The upper end of the dredging rod 401 is located inside the material bottle 301, and the lower end of the dredging rod 401 is located below the bottom tray 2 and is fixedly connected by a connecting plate 402. The lower surface of the bottom tray 2 is fixed with a base plate 404 by multiple connecting rods 403. The base plate 404 is located below the connecting plate 402. An electric push rod for driving the connecting plate 402 and the dredging rod 401 to slide up and down is fixed on the upper surface of the base plate 404. Multiple protruding balls 405 are provided on the surface of the dredging rod 401.

[0039] Understandably, by setting up the unblocking component 4, the electric push rod drives the base plate 404 and multiple unblocking rods 401 to move up and down. Under the action of the convex ball 405, the unblocking rod 401 drives the attractant inside the bottle 301 to flow downward through the connecting pipe 302, ensuring smooth replenishment and preventing the attractant from clogging inside the connecting pipe 302 and affecting replenishment. At the same time, the unblocking rod 401 and the convex ball 405 occupy the space inside the connecting pipe 302, further affecting the passage of the attractant. When the unblocking rod 401 does not move up and down, it can block the connecting pipe 302, preventing the attractant from flowing continuously and causing excessive attractant on a certain tray 2, resulting in waste.

[0040] Specifically, multiple trays 2 are provided with dispersion components 5 for spreading the attractant. The dispersion components 5 include an air pipe 501 fixed at the center of the tray 2 and multiple air nozzles 502 opened on the surface of the air pipe 501. The upper end of the air pipe 501 is located inside the bottle 301. An air pump 503 is fixed on the upper surface of the bottle cap 303. A connector 504 is fixed to the air outlet of the air pump 503. The connector 504 is fixed on the lower surface of the bottle cap 303. The connector 504 is conical to facilitate docking with the upper end of the air pipe 501. The multiple air nozzles 502 are respectively directed toward the lower end of the multiple connecting pipes 302.

[0041] Understandably, since the bait tends to accumulate on the surface of the tray 2 as it slides down through the connecting pipe 302, affecting its contact with termites, a dispersion component 5 is provided. During the up-and-down movement of the unblocking rod 401, the air pump 503 is activated, drawing air into the air pipe 501 and spraying it out through multiple nozzles 502. This disperses the sliding bait, causing it to float above the tray 2 and preventing its accumulation. Simultaneously, the air blowing the bait allows the scent of the wood and the bait to spread rapidly underground, attracting termites into the pre-buried pipe 1. A connector 504 is provided to facilitate the connection between the air pump 503 and the air pipe 501.

[0042] Specifically, the unblocking component 4 also includes a stirring sleeve 406 for agitating the attractant inside the material bottle 301. Multiple stirring rods are fixed on the surface of the stirring sleeve 406. The stirring sleeve 406 slides on the surface of the air pipe 501. Two spiral guide rails 407 are provided on the surface of the air pipe 501. A connecting frame 408 is rotatably mounted on the upper end of the stirring sleeve 406. The connecting frame 408 is fixed to the upper end of the multiple unblocking rods 401.

[0043] Understandably, since the unblocking rod 401 is relatively thin, it has little impact on the attractant inside the bottle 301. Therefore, to prevent the attractant from accumulating inside the bottle 301 and collapsing downwards, a stirring sleeve 406 is provided. During the up-and-down sliding of the unblocking rod 401, the connecting frame 408 drives the stirring sleeve 406 to slide up and down on the surface of the air pipe 501. Under the action of the spiral guide rail 407, the stirring sleeve 406 rotates while sliding up and down, thereby agitating the attractant inside the bottle 301 so that it can collapse downwards smoothly and slide down to the surface of the tray 2 through the connecting pipe 302.

[0044] Specifically, the lower end of the pre-embedded pipe 1 is an open structure, and a support component 6 is provided at the lower end of the pre-embedded pipe 1. The support component 6 includes a support ring 602 fixed to the lower end of the pre-embedded pipe 1 by multiple support rods 601, and the lower end of the base plate 404 is tapered.

[0045] Understandably, since rainwater easily carries soil into the pre-buried pipe 1 through channel 101 during rain, to prevent rainwater and soil from accumulating inside the pre-buried pipe 1 and affecting the use of the tray 2 after it descends, the bottom of the pre-buried pipe 1 is set as an open structure and a support component 6 is installed so that rainwater can be discharged again through the lower end of the pre-buried pipe 1. Under the action of the support component 6, space is provided for the soil. When burying the pre-buried pipe 1, an installation hole matching the diameter of the pre-buried pipe 1 is dug in the ground, and a conical gap is dug at the bottom of the installation hole. After the pre-buried pipe 1 is placed in the installation hole through the support component 6, it is supported by the support component 6. After the soil dries, it accumulates around the support ring 602. When too much soil accumulates, the tray 2 moves downward and the soil is squeezed by the conical bottom plate 404, so that the soil can be spread around, making it easier for the tray 2 to descend to the specified height and avoiding the accumulation of soil from affecting the descent of the tray 2.

[0046] In this invention, an installation hole matching the diameter of the pre-embedded pipe 1 is dug in the ground, and a conical gap is dug at the bottom of the installation hole. The pre-embedded pipe 1 is placed in the installation hole by the support component 6. The lower end of the pre-embedded pipe 1 below the retaining ring 7 is pre-buried under the ground of the embankment. Wood bait is placed on the surface of the tray 2 through the opening, and termite bait is added inside the material bottle 301. The material bottle 301 and the tray 2 are moved downward to the position corresponding to the channel 101 by the transmission component. Then, the electric push rod drives the base plate 404 and multiple unblocking rods 401. Moving up and down, under the action of the convex ball 405, the unblocking rod 401 causes the attractant inside the bottle 301 to flow downward through the connecting pipe 302, smoothly replenishing the material. Simultaneously, as the unblocking rod 401 slides up and down, the connecting frame 408 causes the stirring sleeve 406 to slide up and down on the surface of the air pipe 501. Under the action of the spiral guide rail 407, the stirring sleeve 406 rotates while sliding up and down, agitating the attractant inside the bottle 301, allowing it to fall smoothly downwards and through the connecting pipe... The bait 302 slides down onto the surface of tray 2. As the bait falls, the air pump 503 is activated, drawing air into the air pipe 501 and spraying it out through multiple nozzles 502. This disperses the falling bait, causing it to float above tray 2 and preventing accumulation. Simultaneously, the airflow disperses the bait, rapidly diffusing the wood and the bait's scent underground, attracting termites into the pre-buried pipe 1. When termites enter the surface of tray 2 through channel 101 and begin feeding on the wood, they become contaminated with the bait. After returning to their nest... Contact with other termites causes the termites in the nest to also become infected with the bait and die, thus achieving the purpose of exterminating termites. The bait is replenished to the surface of the tray 2 regularly through the replenishment component 3 and the unblocking component 4, so as to keep the surface of the tray 2 with sufficient bait. When it rains, the rain sensor 8 detects the rain and sends a signal to drive the motor, so that the transmission rope pulls the bait bottle 301 and multiple trays 2 upward, so that they are moved to the upper end of the pre-buried pipe 1, preventing rainwater from entering the surface of the tray 2 through the channel 101 and damaging the bait.
