Description

Technical Field

[0001] This application relates to the field of termite control technology, and in particular to a precise control device and method for termite damage in water conservancy projects. Background Technology

[0002] As crucial infrastructure, water conservancy projects are directly related to the national economy and the safety of people's lives and property. Termites, as highly destructive pests, pose a serious threat to water conservancy projects, especially earthen dams and reservoir dams. Termites bore into the wooden structures or plant fiber materials inside the dams, forming hidden tunnel systems that reduce the structural strength of the project and may even cause safety accidents such as leakage and piping.

[0003] Traditional termite control methods mainly rely on manual inspections and chemical spraying, which are inefficient and cause serious environmental pollution. With the development of IoT and AI technologies, developing a termite control device for water conservancy projects that can monitor and control termites in real time is of great significance for improving the safety management of water conservancy projects.

[0004] Therefore, this application provides a precise control device and method for termite damage in water conservancy projects. Summary of the Invention

[0005] The purpose of this application is to solve at least one technical problem raised in the background art.

[0007] The trapping module is installed on the embankment of the water conservancy project to attract termite activity. The signal acquisition module is connected to the trapping module to monitor termite activity signals in real time. The signal acquisition module is a vibration sensor used to monitor specific frequency vibration signals generated by termites gnawing on wood. The data processing unit is wirelessly connected to the signal acquisition module to analyze and process termite activity data. The data processing unit has a built-in AI algorithm model that can accurately identify the number of termites and assess the level of damage. The early warning output module is connected to the data processing unit and issues an early warning signal when termite activity is detected. The remote control module is connected to the early warning output module for remote powder spraying control. The trapping module consists of a pre-embedded part and an exposed part. The pre-embedded part includes an inlet tray, an expansion tube fixed to the lower end of the inlet tray by bolts, multiple inlet channels equally spaced on the surface of the inlet tray, and a bait tube set inside the inlet tray. The surface of the bait tube has multiple ventilation grooves equally spaced, and the inner wall of the bait tube is threaded with a cover plate.

[0008] By adopting the above technical solution, a combination structure of pre-embedded part and exposed part is used. The pre-embedded part is buried near the dam, and multiple ant entry channels form a directional ant path. The threaded cover plate on the inner wall of the bait cylinder fixes the bait. The vibration sensor can capture the termite feeding characteristic frequency band of 15-35kHz.

[0009] Preferably, the exposed portion includes a support cylinder that is bolted to the upper end of the ant inlet tray, and a photovoltaic power generation system that is bolted to the upper end of the support cylinder.

[0010] By adopting the above technical solution, a support cylinder can be used to provide an installation platform for the photovoltaic power generation system, which is used to continuously supply power to the equipment.

[0011] Preferably, the support cylinder is provided with a bait changing mechanism. The bait changing mechanism consists of a lifting component fixedly installed on the top wall of the support cylinder and a guide component located in the middle of the inner wall of the support cylinder. The lifting component includes a take-up roller fixedly installed on the top wall of the support cylinder, a take-up rope wound on the surface of the take-up roller, and a first motor fixedly installed on the top wall of the support cylinder for driving the take-up roller to rotate. The lower end of the take-up roller is rotatably connected to the upper end of the cover plate through a rotating shaft. The outer surface of the support cylinder is provided with a feeding port, and the inner wall of the feeding port is fixedly installed with a sealing door by bolts.

[0012] By adopting the above technical solution, the first motor can drive the winding roller to rotate. The rotation of the winding roller can be used to wind up and unwind the winding rope, thereby lifting the bait cylinder. When the bait cylinder is lifted to the closed door position, the closed door can be opened to take out the bait cylinder.

[0013] Preferably, the guide assembly includes two guide rails symmetrically fixedly installed on the inner wall of the support cylinder. The inner wall of the guide rail is slidably fitted with a rotating disk through a guide block. The inner wall of the rotating disk is rotatably fitted with the outer surface of the cover plate through a bearing.

[0014] By adopting the above technical solution, when the winding rope lifts the bait cylinder, the guide block will slide along the inner wall of the guide track, thereby guiding the bait cylinder.

[0015] Preferably, the support cylinder is further provided with a spraying mechanism, which consists of a rotating component, a powder spraying component, and a positioning component.

[0016] Preferably, the rotating assembly includes a positioning disk rotatably fitted on the inner wall of the support cylinder, an external gear disk fixedly installed on the upper end of the positioning disk, a second motor fixedly installed on the inner wall of the support cylinder, a crankshaft fixedly installed at the output end of the second motor, a spur gear meshing with the external gear disk fixedly installed at the lower end of the crankshaft, and a through hole for the winding rope to pass through is provided at the center of the positioning disk.

[0017] By adopting the above technical solution, the second motor can drive the spur gear to rotate, and the spur gear can mesh with the external gear disk to drive the positioning disk to rotate.

[0018] Preferably, the positioning component includes three sleeves fixedly mounted in a circumferential array on the upper surface of the cover plate, a positioning pin slidably fitted on the inner wall of the sleeve, a positioning hole formed on the lower surface of the positioning plate and in clearance fit with the positioning pin, and a compression spring provided on the inner wall of the sleeve for driving the positioning pin to insert into the inner wall of the positioning hole.

[0019] By adopting the above technical solution, when the bait cylinder rises, the positioning pin will contact the positioning plate. At this time, the compression spring will contract and drive the positioning pin to retract into the sleeve. The other end of the positioning pin will contact the positioning plate. As the rotating component drives the positioning plate to rotate, the positioning hole will rotate to the position of the positioning pin. At this time, the compression spring will reset and drive the positioning pin to insert into the positioning hole, thereby driving the bait cylinder to rotate synchronously.

[0020] Preferably, the powder spraying assembly includes a drug storage cylinder and a piston cylinder that are fixedly mounted on the outer surface of the support cylinder by bolts. One end of the piston cylinder extends into the interior of the support cylinder. A connecting rod is hinged to the surface of the crankshaft, and a piston is hinged to one end of the connecting rod. The piston and the piston cylinder are fitted with a micron-level clearance. An air inlet pipe and an exhaust pipe are fixedly mounted on one end of the piston cylinder, and one end of the exhaust pipe extends into the interior of the drug storage cylinder. A powder spraying pipe is fixedly mounted on the inner wall of the drug storage cylinder. One end of the powder spraying pipe extends into the interior of the support cylinder, and a dust collection hood is fixedly mounted on the other end of the powder spraying pipe. One-way valves are provided on the surfaces of the air inlet pipe and the exhaust pipe, and a drug dosing pipe is provided on the surface of the drug storage cylinder.

[0021] By adopting the above technical solution, when the second motor rotates, the crankshaft pulls the connecting rod to drive the piston to move back and forth along the inner wall of the piston cylinder. When the piston moves to the left, the intake pipe will draw outside air into the piston cylinder. When the piston moves to the right, the gas in the piston cylinder will enter the medicine storage cylinder along the exhaust pipe. The gas entering the medicine storage cylinder will blow up the medicine powder in the medicine storage cylinder and spray it onto the bait cylinder along the powder spraying pipe. As the bait cylinder rotates, the medicine powder can be evenly sprayed onto the bait cylinder, thereby infecting and killing termites.

[0022] Preferably, the vibration sensor is fixedly installed at the lower end of the bait cylinder, and the sensing end of the vibration sensor extends into the interior of the bait cylinder.

[0023] By adopting the above technical solution, the sensing end extends into the inside of the bait cylinder, which can directly detect the bait vibration signal, avoiding the monitoring lag problem caused by signal attenuation in traditional external installations.

[0024] A method for precise control of termite damage in water conservancy projects includes the following steps: Trapping modules were buried near the dams of water conservancy projects; The trapping module attracts termites. Termite activity signals are monitored in real time using a signal acquisition module; Termite activity data is analyzed and processed through a data processing unit. When termite activity is detected, an early warning signal is issued through the early warning output module; Prevention and control measures are initiated via a remote control module.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The present application describes a precise termite control device and method for water conservancy projects, which uses a trapping module to trap termites, then a signal acquisition module monitors the vibrations generated by termites eating the bait, and a data processing unit analyzes the number of termites. When the number reaches a certain level, an early warning output module issues an alarm, and a remote control module controls a spraying mechanism to spray pesticides on the termites, thereby achieving precise termite control.

[0026] 2. The precise termite control device and method for water conservancy projects described in this application, by setting up a bait replacement mechanism, drives the first motor to raise the bait cylinder to the feeding port position, then opens the closed door to expose the bait cylinder, and then unscrews the cover plate of the bait cylinder, so that the bait cylinder can be taken out for bait replacement without digging out the pre-buried part, which facilitates the replacement of bait.

[0027] 3. The precision termite control device and method for water conservancy projects described in this application, by setting up a spraying mechanism, drives a second motor, and uses the meshing transmission of a spur gear and an external gear disk to drive the positioning disk to rotate. When the positioning component limits the bait cylinder and the positioning disk, the second motor can drive the bait cylinder to rotate. At the same time, the crankshaft will pull the connecting rod to drive the piston to move back and forth along the inner wall of the piston cylinder. Thus, gas can be injected into the medicine storage cylinder through the exhaust pipe, and the medicine powder in the medicine storage cylinder will be blown up. The blown medicine powder will be sprayed onto the bait cylinder along the powder spraying pipe. With the rotation of the bait cylinder, the medicine powder can be evenly sprayed onto the bait cylinder. Attached Figure Description

[0030] The following combination Figure 1 Appendix 8 provides a further detailed description of this application.

[0031] Example 1 Please refer to the following carefully. Figures 1 to 2 ,as well as Figures 4 to 7 A precision control device for termite damage in water conservancy projects includes a trapping module 100, a signal acquisition module 200, a data processing unit 500, an early warning output module 600, and a remote control module 700.

[0032] The trapping module 100 is installed on the embankment of the water conservancy project to attract termite activity. The signal acquisition module 200 is connected to the trapping module 100 to monitor termite activity signals in real time. The signal acquisition module 200 is a vibration sensor 201 used to monitor the specific frequency vibration signals generated by termites gnawing on wood. The data processing unit 500 is wirelessly connected to the signal acquisition module 200 to analyze and process termite activity data. The data processing unit 500 has a built-in AI algorithm model that can accurately identify the number of termites and assess the level of damage. The early warning output module 600 is connected to the data processing unit 500 and issues an early warning signal when termite activity is detected. The remote control module 700 is connected to the early warning output module 600 for remote dust spraying control.

[0033] The trapping module 100 consists of a pre-embedded part and an exposed part. The pre-embedded part includes an ant-inlet tray 101, an expansion tube 102 fixedly installed at the lower end of the ant-inlet tray 101 by bolts, multiple ant-inlet channels 103 equidistantly opened on the surface of the ant-inlet tray 101, and a bait tube 104 disposed inside the ant-inlet tray 101. The surface of the bait tube 104 is provided with multiple ventilation grooves 105 equidistantly opened. A cover plate 106 is threadedly connected to the inner wall of the bait tube 104. A vibration sensor 201 is fixedly installed at the lower end of the bait tube 104, and the sensing end 202 of the vibration sensor 201 extends into the interior of the bait tube 104.

[0034] Specifically, the bait is placed into the bait cylinder 104, and then the cover plate 106 is tightened. The pre-embedded part is then buried near the dam. Multiple ant entry channels 103 form a directional ant path. The threaded cover plate 106 on the inner wall of the bait cylinder 104 fixes the bait. The vibration sensor 201 can capture the termite feeding characteristic frequency band of 15-35kHz. The sensing end 202 extends into the bait cylinder 104 and can directly detect the vibration signal generated by termites feeding on the bait.

[0035] Please refer to this carefully. Figures 2 to 4 The exposed part includes a support cylinder 107 that is fixedly installed on the upper end of the ant tray 101 by bolts, and a photovoltaic power generation system 108 that is fixedly installed on the upper end of the support cylinder 107 by bolts.

[0036] Specifically, the support cylinder 107 can provide an installation platform for the photovoltaic power generation system 108, which is used to continuously supply power to the equipment.

[0037] The working principle of this embodiment is as follows: the trapping module 100 is used to trap termites, and then the signal acquisition module 200 monitors the vibration generated by the termites eating the bait. The data processing unit 500 analyzes the number of termites. When the number reaches a certain level, the early warning output module 600 issues an alarm, and the remote control module 700 controls the spraying mechanism 400 to spray pesticides on the termites, thereby achieving precise termite control.

[0038] Example 2 Compared with Embodiment 1, another implementation of this application is as follows: Please refer to this carefully. Figures 2 to 4 ,as well as Figure 7 The support cylinder 107 is equipped with a bait changing mechanism 300. The bait changing mechanism 300 consists of a lifting assembly fixedly installed on the inner top wall of the support cylinder 107 and a guide assembly located in the middle of the inner wall of the support cylinder 107. The lifting assembly includes a take-up roller 301 fixedly installed on the inner top wall of the support cylinder 107, a take-up rope 302 wound on the surface of the take-up roller 301, and a first motor 303 fixedly installed on the inner top wall of the support cylinder 107 for driving the take-up roller 301 to rotate. The lower end of the take-up roller 301 is rotatably connected to the upper end of the cover plate 106 through a rotating shaft. The outer surface of the support cylinder 107 is provided with a feeding port. The inner wall of the feeding port is fixedly installed with a sealing door 304 by bolts.

[0039] Specifically, in the initial position, the bait cylinder 104 is inside the expansion cylinder 102. Termites will enter the bait cylinder 104 along the ant entry channel 103. When it is necessary to change the bait, the first motor 303 can drive the winding roller 301 to rotate. The rotation of the winding roller 301 can wind up and unwind the winding rope 302, thereby lifting the bait cylinder 104. When the bait cylinder 104 is lifted to the closed door 304 position, the closed door 304 can be opened to take out the bait cylinder 104.

[0040] Please refer to this carefully. Figure 3 and Figure 8 The guide assembly includes two guide rails 305 symmetrically fixedly installed on the inner wall of the support cylinder 107. The inner wall of the guide rail 305 is slidably fitted with a rotating disk 307 through a guide block 306. The inner wall of the rotating disk 307 is rotatably fitted with the outer surface of the cover plate 106 through a bearing.

[0041] Specifically, when the winding rope 302 lifts the bait cylinder 104, the guide block 306 slides along the inner wall of the guide rail 305, thereby guiding the bait cylinder 104.

[0042] The working principle of this embodiment is as follows: the first motor 303 can drive the bait cylinder 104 to rise to the feeding port position. Then, the closed door 304 is opened to expose the bait cylinder 104. Then, the cover plate 106 is unscrewed from the bait cylinder 104, so that the bait cylinder 104 can be taken out for bait replacement without digging out the pre-buried part, which facilitates the replacement of bait.

[0043] Example 3 Compared with Embodiment 1, another implementation of this application is as follows: Please refer to this carefully. Figure 3 and Figure 7The support cylinder 107 is also equipped with a spraying mechanism 400. The spraying mechanism 400 consists of a rotating component, a powder spraying component, and a positioning component. The rotating component includes a positioning disk 401 that is rotatably fitted on the inner wall of the support cylinder 107, an external gear disk 402 that is fixedly installed on the upper end of the positioning disk 401, and a second motor 403 that is fixedly installed on the inner wall of the support cylinder 107. A crankshaft 404 is fixedly installed at the output end of the second motor 403. A spur gear 405 that meshes with the external gear disk 402 is fixedly installed at the lower end of the crankshaft 404. A through hole for the winding rope 302 to pass through is opened at the center of the positioning disk 401.

[0044] Specifically, the second motor 403 can drive the spur gear 405 to rotate, and the spur gear 405 meshes with the external gear disk 402 to drive the positioning disk 401 to rotate.

[0045] Please refer to this carefully. Figure 4 and Figure 8 The positioning assembly includes three sleeves 415 fixedly mounted in a circumferential array on the upper surface of the cover plate 106, a positioning pin 416 slidably fitted on the inner wall of the sleeve 415, a positioning hole formed on the lower surface of the positioning plate 401 and in clearance fit with the positioning pin 416, and a compression spring 417 provided on the inner wall of the sleeve 415 for driving the positioning pin 416 to insert into the inner wall of the positioning hole.

[0046] Specifically, when the bait cylinder 104 rises, the positioning pin 416 contacts the positioning disk 401. At this time, the compression spring 417 contracts, which drives the positioning pin 416 to retract into the sleeve 415, and the other end of the positioning pin 416 contacts the positioning disk 401. As the rotating component drives the positioning disk 401 to rotate, the positioning hole will rotate to the position of the positioning pin 416. At this time, the compression spring 417 resets, which drives the positioning pin 416 to insert into the positioning hole, thereby driving the bait cylinder 104 to rotate synchronously.

[0047] Please refer to this carefully. Figure 1 , Figure 3 ,as well as Figures 7 to 8The powder spraying assembly includes a drug storage cylinder 406 and a piston cylinder 407, which are fixedly mounted on the outer surface of the support cylinder 107 by bolts. One end of the piston cylinder 407 extends into the interior of the support cylinder 107. A connecting rod 408 is hinged to the surface of the crankshaft 404, and a piston 409 is hinged to one end of the connecting rod 408. The piston 409 and the piston cylinder 407 are fitted with a micron-level clearance. An air inlet pipe 410 and an exhaust pipe 411 are fixedly mounted on one end of the piston cylinder 407, respectively. One end of the exhaust pipe 411 extends into the interior of the drug storage cylinder 406. A powder spraying pipe 412 is fixedly mounted on the inner wall of the drug storage cylinder 406. One end of the powder spraying pipe 412 extends into the interior of the support cylinder 107, and a dust collection hood 413 is fixedly mounted on the other end of the powder spraying pipe 412. One-way valves are provided on the surfaces of the air inlet pipe 410 and the exhaust pipe 411. A dosing pipe 414 is provided on the surface of the drug storage cylinder 406.

[0048] Specifically, when the second motor 403 rotates, the crankshaft 404 pulls the connecting rod 408 to drive the piston 409 to reciprocate along the inner wall of the piston cylinder 407. When the piston 409 moves to the left, the intake pipe 410 draws in outside air into the piston cylinder 407. When the piston 409 moves to the right, the gas in the piston cylinder 407 enters the medicine storage cylinder 406 along the exhaust pipe 411. The gas entering the medicine storage cylinder 406 blows up the medicine powder in the medicine storage cylinder 406 and sprays it onto the bait cylinder 104 along the powder spraying pipe 412. As the bait cylinder 104 rotates, the medicine powder can be evenly sprayed onto the bait cylinder 104, thereby infecting and killing termites.

[0049] The working principle of this embodiment is as follows: the second motor 403 is driven to rotate the positioning disk 401 by the meshing transmission of the spur gear 405 and the external gear disk 402. When the positioning component limits the bait cylinder 104 and the positioning disk 401, the second motor 403 can drive the bait cylinder 104 to rotate. At the same time, the crankshaft 404 will pull the connecting rod 408 to drive the piston 409 to move back and forth along the inner wall of the piston cylinder 407. Thus, gas can be injected into the medicine storage cylinder 406 by the exhaust pipe 411, and the medicine powder in the medicine storage cylinder 406 will be blown up. The blown medicine powder will be sprayed into the bait cylinder 104 along the powder spraying pipe 412. With the rotation of the bait cylinder 104, the medicine powder can be evenly sprayed on the bait cylinder 104.

[0050] A method for precise control of termite damage in water conservancy projects includes the following steps: 100 trapping modules were buried near the dam of the water conservancy project; The trapping module 100 attracts termite activity; The signal acquisition module 200 monitors termite activity signals in real time. The data processing unit 500 analyzes and processes termite activity data. When termite activity is detected, an early warning signal is issued through the early warning output module 600; Prevention and control measures are initiated via remote control module 700.

[0051] Operating steps: The embedded part and the exposed part are assembled and fixed with bolts. Then, special bait is put into the bait cylinder 104 and the cover plate 106 is tightened.

[0052] Then, a pre-embedded pit with a depth of ≥30cm is excavated at the selected location on the dam, and the pre-embedded part is buried; After being buried, the vibration sensor 201 automatically monitors vibration signals in the 15-35kHz frequency band. The data is wirelessly transmitted to the data processing unit 500 via LoRa, and the AI ​​algorithm analyzes the number of termites and the level of damage in real time. When the number of termites reaches a certain level, the early warning output module 600 sends an early warning signal, and the remote control module 700 starts the first motor 303 and the spraying mechanism 400. First, the first motor 303 is driven to raise the bait cylinder 104. After the positioning pin 416 on the positioning component is inserted into the positioning hole, the second motor 403 is driven to rotate the crankshaft 404 and the spur gear 405. The piston 409 reciprocates in the piston cylinder 407. At this time, the gas in the piston cylinder 407 enters the medicine storage cylinder 406 and blows up the medicine powder. The medicine powder is sprayed onto the bait cylinder 104 through the powder spraying pipe 412. At the same time, the spur gear 405 meshes with the external gear disk 402 to drive the bait cylinder 104 to rotate, so that the medicine powder can be sprayed evenly onto the bait cylinder 104. When it is necessary to change the bait, the first motor 303 drives the take-up roller 301 to rotate, thereby lifting the bait cylinder 104. When the bait cylinder 104 is lifted to the position of the closed door 304, the closed door 304 can be opened to take out the bait cylinder 104.
