DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0030] Please refer to Figure 1-11 A termite trapping device for water conservancy includes a device body 1, wherein the device body 1 includes an inner tube 3 and an outer tube 4 arranged coaxially, wherein the side walls of the inner tube 3 and the outer tube 4 are both provided with termite entry and exit holes 5, and an attracting module 6 is provided in the inner tube; when in use, the device body 1 is inserted or buried in or around a water conservancy facility, and if termites exist in the environment, the termites will enter the inner tube 3 and the outer tube 4 at the termite entry and exit holes 5 through the internal attracting module 6, and a plurality of partitions arranged in an array are provided between the inner tube 3 and the outer tube 4, and through holes are provided on the partitions A medicine filling cavity 11 is arranged between adjacent partitions, and a medicine applying device 7 is inserted and removed in the medicine filling cavity 11. After termites enter the interior, an ant alarm is issued, and then the medicine applying device 7 is inserted into the medicine filling cavity 11, so as to kill the internal termites. A top seat 8 is arranged on the top circumference of the outer cylinder 4, and an end cover 9 is arranged on the surface of the top seat 8. When in use, the end cover 9 is closed to prevent the internal termites from crawling out. A cone head 2 is arranged at the bottom of the outer cylinder 4, and a plurality of drainage holes 21 are arranged on the circumference of the cone head 2 to prevent water accumulation inside the device body 1.

[0031] In this embodiment, a plurality of support plates 31 are provided below the inner wall of the inner tube 3, and a bracket 311 for supporting the attracting module 6 is provided above the support plate 31; that is, the arrangement of the support plate 31 and the bracket 311 can hold up the attracting module 6, so that the attracting module 6 is suspended in the air, thereby improving the attracting effect on termites and also facilitating the termites to gnaw on the bait.

[0032] Among them, the luring module 6 includes a wooden bait 61, and the two ends of the wooden bait 61 are clamped and fixed by a lower support seat 62 and an upper support seat 63. The surface circumference of the lower support seat 62 is provided with a plurality of limiting fins 64, and the limiting fins 64 correspond to the wooden bait 61 one by one to prevent the wooden bait from tilting and falling between the lower support seat 62 and the upper support seat 63; wherein the lower support seat 62 is provided with a circular chamfer on the bottom circumference that cooperates with the bracket 311, so as to improve the supporting stability of the luring module, and a control box 65 for ant alarm is provided above the upper support seat 63, and a through hole 66 extending downward is provided at the center of the control box 65.

[0033] In this embodiment, an electromagnetic Hall trigger device and an alarm chip are provided in the control box 65; when termites eat the wooden bait 61, the electromagnetic Hall trigger device will be triggered. Once the alarm chip is triggered, a signal will be sent, and the signal will be transmitted to the monitoring system through the Internet of Things, thereby issuing an ant alarm; the electromagnetic Hall trigger device can also be an on-off trigger, a camera recognition trigger, etc., which will not be described in detail here. When the ant situation is found, the external platform receives the alarm signal, and the staff opens the end cover 9 after reaching the predetermined position, so that the drug application device 7 is quickly placed in the drug filling cavity 11, so as to kill the internal termites.

[0034] As a preferred solution, the plurality of wooden baits 61 are arranged in a circular array between the lower support seat 62 and the upper support seat 63, and a gap is left between each two adjacent wooden baits 61 for termites to enter and exit, so as to facilitate termites to enter and exit to gnaw. The through hole 66 is provided at the center of the plurality of wooden baits 61, wherein the through hole 66 is a reserved hole for facilitating the application of medicine inside.

[0035] Please refer again Figure 8-11 The drug application device 7 includes a mounting plate 71, and a plurality of vertically arranged drug storage tubes 72 are provided on the bottom surface of the mounting plate 71. The drug storage tubes 72 correspond to the drug filling chambers 11 one by one. A cylindrical drug storage tube 73 is provided at the center of the bottom surface of the mounting plate 71. The drug storage tube 73 corresponds to the through hole 66. The insides of the drug storage tubes 72 and 73 are hollow, and the outer walls are provided with air permeable grooves 74. When the inside is filled with drugs, the drug smell or powder particles will quickly diffuse outward through the air permeable grooves 74, thereby killing the internal termites.

[0036] When in use, the medicine in the medicine storage tube 1 72 and the medicine storage tube 2 73 is placed in advance, and after placement, the end cover 9 is opened and then inserted into the medicine filling cavity 11. This process can shorten the drug application cycle, reduce the contact with the device body 1, and prevent termites from escaping sensitively, thereby achieving a highly efficient killing effect.

[0037] Since the second medicine storage tube 73 is located in the middle of the multiple wooden baits 61, when the second medicine storage tube 73 is inserted into the wooden bait 61, the termites around the bait can be directly killed. At the same time, the termites will crawl outward through the termite entrance and exit hole 5 into the medicine filling cavity 11 due to the stimulation of the medicine. The medicine filling cavity 11 is also inserted with the first medicine storage tube, and the crawling termites can be killed again through the first medicine storage tube, which greatly improves the killing effect.

[0038] In order to facilitate the addition of medicine into the medicine storage tube 1 72 and the medicine storage tube 2 73, the surface of the mounting plate 71 is provided with a medicine dispensing port 1 712 and a medicine dispensing port 2 716, and the medicine dispensing port 1 712 is connected to the medicine storage tube 1 72, and the medicine dispensing port 2 716 is connected to the medicine storage tube 2 73. A turntable 75 for covering the medicine dispensing port 1 712 and the medicine dispensing port 2 716 is also provided above the mounting plate 71. When the medicine is covered, the turntable is rotated to cover the medicine dispensing port 1 712 and the medicine dispensing port 2 716 to prevent the internal medicine or odor from diffusing outward. When in use, first rotate the turntable 75, and after rotation, the medicine dispensing port 1 712 and the medicine dispensing port 2 716 leak out. At this time, add medicine into the medicine dispensing port 1 712 and the medicine dispensing port 2 716, so that the medicine falls into the corresponding medicine storage tube 1 72 and the medicine storage tube 2 73; after the medicine is added, the turntable 75 rotates again to cover the medicine dispensing port 1 712 and the medicine dispensing port 2 716.

[0039] The cross section of the medicine dispensing port 1 712 is the same as the inner wall of the medicine storage tube 1 72 , the cross section of the medicine storage tube 2 73 is circular, the cross section of the medicine dispensing port 2 716 is semicircular, and the medicine dispensing port 2 716 is always located directly above the medicine storage tube 2 73 .

[0040] In addition, the surface of the mounting plate 71 is provided with an outer annular groove 711 which is recessed downward, and the plurality of drug application ports 712 are all arranged in the outer annular groove 711. The lower surface of the turntable 75 is provided with an annular protrusion 751 which cooperates with the outer annular groove 711. The annular protrusion 751 is provided with a reserved opening 76 which passes through the turntable. When applying the drug, the reserved opening 76 corresponds to the drug application port 712. When the drug application is completed or the drug is filled, the reserved opening 76 is staggered with the drug application port 712. A semicircular reserved opening 2 77 is provided at the center of the turntable 75. The reserved opening 2 77 is arranged opposite to the drug application port 2 716.

[0041] In this embodiment, the cross-sections of the outer annular groove 711 and the annular protrusion 751 are both inverted T-shaped. After the outer annular groove 711 and the annular protrusion 751 are matched, the lower surface of the turntable 75 is always rotated and fitted with the surface of the mounting plate 71; when in use, it is only necessary to rotate the turntable 75. After the turntable 75 is rotated, the reserved opening 1 76 and the medicine dispensing opening 1 712, and the reserved opening 2 77 and the medicine dispensing opening 2 716 can be overlapped and corresponded respectively; similarly, after the turntable 75 is rotated in the direction, the medicine dispensing opening 1 712 and the medicine dispensing opening 2 716 can be completely covered, thereby preventing the internal medicine or odor from diffusing outward.

[0042] In order to realize the automatic rebound rotation of the turntable, the surface of the mounting plate 71 is also provided with an inner annular groove 713, the cross-section of the inner annular groove 713 is semicircular, and a fixing block 714 and an arc spring 715 are provided inside the inner annular groove 713. The fixing block 714 is fixed to the inner wall of the inner annular groove 713, and the arc spring 715 is arranged along the track of the inner annular groove 713. A semicircular push rod 752 is provided on the bottom surface of the turntable 75, and one end of the arc spring 715 is fixedly connected to the fixing block 714, and the other end is fixedly connected to one end of the semicircular push rod 752.

[0043] It can be understood that since the cross-sections of the inner annular groove 713 and the semicircular push rod 752 are both semicircular, the semicircular push rod 752 can rotate in the inner annular groove 713 when the turntable 75 rotates; when the semicircular push rod 752 rotates in the inner annular groove 713, the arc spring 715 will be compressed, and when the turntable 75 is released, the arc spring 715 pops open and returns the turntable to its original position.

[0044] The bottom surface of the rotating disk 75 is always in contact with the surface of the mounting disk 71 , and when the rotating disk 75 rotates, the arc spring 715 is squeezed or stretched by the semicircular push rod 752 .

[0045] In normal state, the arc spring 715 is in a natural state, and the rotating disk 75 covers the first and second dispensing ports 712 and 716 on the surface of the mounting disk 71; When it is necessary to add medicine, the turntable 75 is rotated to make the semicircular push rod 752 rotate in the inner annular groove 713 to compress the arc spring 715. After the rotation, the reserved opening 1 76 and the medicine application opening 1 712 coincide with each other, and the reserved opening 2 77 and the medicine application opening 2 716 coincide with each other. At this time, the medicine storage tube 1 72 and the medicine storage tube 2 73 are connected at the top, and termite killing medicine can be added to the reserved opening 1 76 (medicine application opening 1 712) and the reserved opening 2 77 (medicine application opening 2 716). After the medicine is added, it falls into the corresponding medicine storage tube. After the addition of medicine is completed, the turntable 75 is released, and the arc spring 715 rebounds, causing the turntable 75 to rotate in the opposite direction and return to a natural state, so that the turntable 75 covers the medicine application port 1 712 and the medicine application port 2 716 on the surface of the mounting plate 71 again, thereby preventing the internal medicine from spilling and the odor from overflowing, and also helping to improve the killing effect on termites.

[0046] As a preferred solution, the surface array of the top seat 8 is provided with three magnetic grooves 81, and the three magnetic grooves 81 are arranged in an equilateral triangle. The lower surface of the mounting plate 71 is provided with a magnetic block 717 that matches the magnetic groove 81; when in use, the drug storage tube falls into the corresponding drug filling cavity and the magnetic block 717 falls into the corresponding magnetic groove 81, which can limit the position and improve the stabilization effect.

[0047] Based on the above embodiment, in order to facilitate the control of the rotation of the turntable 75 , a handle may be further provided on the surface of the turntable 75 .

[0048] Based on the above embodiment, the bottom surface of the end cover 9 is also provided with a magnetic block corresponding to the magnetic groove 81. When in use, the end cover 9 is directly covered on the top seat and can be used for termite monitoring. When termites are detected and need to be killed, the end cover is removed and the pesticide application device 7 is placed.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
