Description

Technical Field

[0001] The present application relates to the technical field of pest control, and in particular to an ant monitoring device. Background Art

[0002] Termites are one of the most damaging species for banks and are the fastest and least likely to be discovered.

[0003] Reservoir dam breach refers to the water pressure caused by water infiltration into the caves caused by excessive floods or digging holes by animals in the dam, or the failure to deal with the hidden dangers of the dam in a timely manner, which causes the water in the reservoir to suddenly lose the dam's barrier and quickly pour downstream. There have been many disasters in history. Its characteristics are: the peak flow, flow rate, and destructive power of the dam breach flood are far greater than those of ordinary rainstorms and floods. The prominent manifestations are: concentrated water volume, large peak flow, strong destructive power, and serious losses.

[0004] When a dam breaks, the flood water is turbulent and turbulent, and it is difficult to protect the downstream. The maximum flow of the dam breaks occurs at the dam site, and the water in the reservoir is often drained in a very short time. The more water the reservoir can store, the higher the head at the dam site, and the greater the destructive power. Wherever the flood passes, farmland is often destroyed, villages are flooded, towns, factories, mines, enterprises and public facilities are instantly destroyed, and people have no time to escape or relocate. The disaster caused by the dam break flood is devastating.

[0005] According to different goals of termite control (prevention and control), termite control business can be divided into termite control for building construction, termite control for water conservancy projects, termite control for agricultural and forestry crops, and termite control for landscaping, etc. (This device is not applicable to building construction projects that have been completed or renovated).

[0006] Termites can also harm civil engineering projects, especially water conservancy projects. On the one hand, black-winged soil termites like to eat soil, and Formosan white termites like to build deep nests, so they often dig holes in the soil, and the loose soil poses a safety hazard to civil engineering projects. On the other hand, black-winged soil termites dig holes and runways, which will reduce the design performance of buildings such as embankments, gates, spillways, and hydropower stations, causing great harm to water conservancy projects.

[0007] Therefore, in actual anti-ant work, it is particularly important to conduct real-time monitoring and inspection, deal with ant situations in a timely manner, and try to avoid dam breach accidents. Summary of the invention

[0047] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0048] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0049] According to an embodiment of the present application, a device for monitoring ant conditions is provided, such as Figure 1A It is a perspective reference diagram of an ant monitoring device according to an embodiment of the present application. Figure 1B FIG. 1 is a cross-sectional reference diagram of an ant monitoring device according to an embodiment of the present application. Figure 1A and Figure 1B , the device comprises:

[0050] A cavity 1 having a receiving cavity. The receiving cavity inside the cavity 1 is used to set related structures and place ant (termites are used as an example throughout the text) bait.

[0051] A carrier 2 is provided in the accommodating cavity for carrying bait. For example, the carrier 2 is plate-shaped and has a shape that matches the cross-section of the cavity 1, for example, a circular plate. Figure 1A As shown, a stop platform 7 may be provided below the carrier 2 to limit the lowest position of the carrier 2 .

[0052] An elastic component 3 is provided on one side of the carrier 2 for supporting the carrier 2. The length of the elastic component 3 changes with the weight of the bait, thereby driving the carrier 2 to move along the axial direction (the height direction of the device shown in FIG. 1 ) of the cavity 1. Exemplarily, the elastic component 3 can be a spring.

[0053] The rod 4 is arranged on the other side of the carrier 2 and extends axially along the cavity 1. One end of the rod 4 is passed through the upper cover 11 of the cavity 1, and extends out of the upper cover 11 or increases the length of the upper cover 11 as the bait decreases. It should be noted that the "heavier" and "lighter" mentioned in the present disclosure are relative, expressing the changes that occur in the process of changing from heavy to light, and are not intended to emphasize specific weight or lightness.

[0054] The visually striking portion 5 (such as Figure 1A The flexible strip 51 is shown. Figure 3 The visually striking portion 5 is shown as an annular color band 52), and the visually striking portion 5 is in a shielded state when the bait is heavier and is shielded by the other of the rod 4 and the upper cover 11 (for example, the visually striking portion 5 is located in the accommodating cavity of the cavity 1; for another example, Figure 2C The visually striking portion 5 is shown in the case where it is located in the guide tube 111; for another example, referring to Figure 4 It is conceivable that the crown 42 covers the annular ribbon 52), and the exposed state that is not blocked when the bait is lighter (such as Figure 1A , Figure 2A , Figure 4 shown).

[0055] By using the device disclosed in this embodiment, termite bait can be placed on the support member 2 to attract termites to enter. As the bait gradually becomes lighter, the elastic member 3 stretches to push the support member 2 to move upward, thereby driving the rod 4 to extend out of the upper cover 11 (from not extending to extending), or driving the rod 4 to extend further out of the upper cover 11 (from already extending to extending more). Due to the relative misalignment between the rod 4 and the upper cover 11, the visually conspicuous portion 5 that was previously in a blocked state becomes exposed, so that the staff can quickly, accurately and timely discover the ant situation during the patrol process.

[0056] Optionally, in an implementation of this embodiment, as Figure 1AAs shown, the cavity 1 has a cone portion 13, a cylindrical portion 12 and an upper cover 11. The cone portion 13 is integrally formed or connected (for example, threadedly connected) with the cylindrical portion 12. The upper cover 11 is used to cover the end of the cylindrical portion 12 away from the cone portion 13; a hole for ants to enter and exit is opened on the wall of the cavity 1, which is also a hole for bait odor dispersion. In this implementation, the upper part adopts a cylindrical portion 12 and the lower part adopts a cone portion 13. Compared with the existing tubular monitoring device, it is not only convenient to hammer into the soil, but also the device is easy to install and does not damage the dam body. The surrounding soil will naturally be squeezed outward during the burial process, which increases the scouring capacity of the dam by rainwater.

[0057] Optionally, in an implementation of this embodiment, the cavity 1 may be made of high-density polyethylene material.

[0058] Optionally, in one implementation of this embodiment, the rod 4 has a first state in which it does not extend out of the upper cover 11 when the bait is heavy, and a second state in which it extends out of the upper cover 11 when the bait is light. Figure 1A As shown, the visually striking portion 5 is disposed at one end of the rod 4 close to the upper cover 11. For example, the visually striking portion 5 is a flexible strip 51 connected to the rod 4, and is wound around the rod 4 in the first state of the rod 4, and extends out of the upper cover 11 and unfolds in the second state of the rod 4. The flexible strip 51 can be a cloth strip, which is wound on the rod 4 and between the rod 4 and the upper cover 11 in the first state of the rod; and extends out of the upper cover 11 and unfolds (hangs down or flutters in the wind) in the second state.

[0059] Optionally, in this implementation, if Figure 1A As shown, there are multiple flexible strips 51, which are sequentially distributed along the axial direction of the rod 4. The number of flexible strips 51 extending out of the upper cover 11 can be used to measure the severity of the termite situation. For example, in a design with three flexible strips 51, when 1 / 2 / 3 flexible strips extend out of the upper cover 11, it is slightly suspected / moderately suspected / highly suspected of termite invasion.

[0060] Alternatively, if Figure 3 As shown, the visually striking portion 5 can also be an annular ribbon 52 arranged on the rod 4. Different hatching lines in the figure represent different colors, and different colors represent different levels of ant sentiment. The annular ribbon 52 is hidden in the upper cover 11 or the cavity 1 in the first state of the rod 4, and extends out of the upper cover 11 and is exposed in the second state of the rod 4. The annular ribbon 52 can be a striking color, such as red, orange, etc., and its function is the same as that of the flexible strip 51. For the sake of being eye-catching, the diameter of the rod 4 can be designed to be larger, and the width of the annular ribbon 52 can be set wider, so that the annular ribbon 52 can be more easily observed.

[0061] Optionally, in an implementation of this embodiment, the rod 4 and the upper cover 11 are relatively slidable and sealed to reduce the impact of rainy days on the effectiveness of the bait and the equipment.

[0062] Optionally, in an implementation of this embodiment, as Figure 1A and Figure 1B As shown, the ant monitoring device also includes an alarm mechanism. The alarm mechanism includes an alarm a arranged outside the cavity 1, a power supply b for supplying power to the alarm a, and a conductive line c connecting the power supply a and the alarm b;

[0063] The conductive circuit c has a first contact d1 fixed in position and a second contact d2 opposite to the first contact d1 and moving with the movement of the rod 4. The second contact d2 has a separation state in which it is separated from the first contact d1 when the bait is heavy, and a contact state in which it contacts the first contact d1 to turn on the alarm a when the bait is light.

[0064] With this implementation, when the ant situation reaches a certain level, the carrier 2 moves upward to drive the rod 4 to move upward to a certain level (for example, when all the flexible strips 51 / annular ribbons 52 extend out of the upper cover 11), the second contact d2 contacts the first contact d1 to form a conductive path, and the alarm a sounds an alarm, for example, the buzzer starts to sound, the LED starts to flash, or the signal transmitter (for example, a wireless signal transmitter) starts to send information reminders to the signal collection device. In this way, the attention of relevant personnel can be drawn in a timely manner in the form of sound, light, electricity, etc. And if used in combination with the visually conspicuous part 5, it is more conducive to the relevant personnel to discover the ant situation in a timely manner.

[0065] For example, in this implementation, the power source b is a battery 8 fixed in the accommodating cavity and inside the upper cover 11, the battery 8 is sealed by an anti-corrosion film, one electrode of the battery 8 is electrically connected to the alarm a, and the other electrode of the battery 8 serves as the first contact d1. The second contact d2 is the tip of a conductive needle 9 electrically connected to the alarm a, and the conductive needle 9 is insulated from the rod 4, for example, an insulating pad is provided between the two. The conductive needle 9 is provided to move with the rod 4 and is opposite to the other electrode of the battery, so that the second contact d2 pierces the anti-corrosion film and contacts the first contact d1 as the rod 4 moves.

[0066] Figure 2A is a perspective schematic diagram of an ant monitoring device according to an embodiment of the present application, Figure 2B is a cross-sectional schematic diagram of an ant monitoring device according to an embodiment of the present application. Figure 2A and Figure 2B In addition to Figure 1A and Figure 1BIn addition to the structure of the ant monitoring device, there is also an attractant material pipe 6 located inside the cavity 1, which is provided with holes for ants to enter and exit. The attractant material pipe 6 can be made of a stainless steel pipe. The rod 4 passes through the attractant material pipe 6. One end of the attractant material pipe 6 is fixed to the carrier 2, and the other end is spaced from the upper cover 11 when the bait is heavy, so as to provide a moving space for the rod 4 during the process of reducing the bait.

[0067] By adopting this embodiment, the bait that likes to eat can be placed outside the attracting material tube 6 and above the carrier 2, and the more attractive attracting bait can be placed inside the attracting material tube 6, so as to capture termites more reasonably and at a lower cost. In addition, the attracting material tube 6 can realize the limiting and guiding function of the rod 4, reducing the possibility of equipment failure.

[0068] Optionally, in an implementation of this embodiment, as Figure 2A , Figure 2B and Figure 2C As shown, the upper cover 11 may further include a guide tube 111, which is a part of the upper cover 11 and is used to guide the movement of the rod 4 and to shield the visually striking portion 5 of the rod 4 when the rod 4 is in the first state. Figure 2A The second state of the rod 4 is shown. Figure 2C The first state of the rod 4 is shown. In the first state, the visually striking portion 5 on the rod 4 is blocked by the guide tube 111 of the upper cover 11 (the flexible strip 51 is wrapped around the rod 4 and rolled into the guide tube 111), and in the second state, the visually striking portion 5 on the rod 4 at least partially extends out of the upper cover 11.

[0069] Optionally, in an implementation of this embodiment, as Figure 2C As shown, a rain cap g can also be provided above the alarm a. The rain cap g can be provided to protect the alarm a, or it can be provided with a larger size (for example, larger than the diameter of the guide tube 111) to cover the opening of the guide tube 111 to prevent rainwater from entering the guide tube 111.

[0070] Optionally, in an implementation of this embodiment, as Figure 2D As shown, the guide tube 111 and the bait tube 6 are arranged to be coaxial, and the inner diameter of the former is larger than the outer diameter of the latter, so that as the bait becomes lighter, the bait tube 6 can be inserted into the guide tube 111 and the conductive needle 9 is brought into contact with the battery 8. Of course, in other implementations, the conductive needle 9 can be arranged on the top of the bait tube 6, so that there is no need to deliberately limit the relationship between the inner diameter and the outer diameter of the guide tube 111 and the bait tube 6.

[0071] Optionally, in one implementation of this embodiment, the ant monitoring device further includes: an alarm a installed at the top of the rod 4, which sends out an alarm by sound, light, or electricity, for example, it can be a buzzer, an LED light, or a wireless signal transmitter. A battery 8 installed in the accommodating cavity and inside the upper cover 11, the battery 8 is sealed by an anti-corrosion film to avoid or reduce the influence of the external environment on the battery performance, and one electrode of the battery 8 is electrically connected to the alarm a. A conductive needle 9 is installed at one end of the attractant tube 6 close to the upper cover 11, insulated from the attractant tube 6 (for example, an insulating pad is provided between the two) and opposite to the battery 8, the conductive needle 9 is electrically connected to the alarm a, and has a fifth state of being away from the battery 8 when the bait is heavier, and a sixth state of piercing the anti-corrosion film to electrically connect to the other electrode of the battery 8 to form a conductive path when the bait is lighter.

[0072] With this implementation, when the insect situation reaches a certain degree, the support member 2 moves upward to drive the rod 4 to move upward to a certain degree (for example, when all the flexible strips 51 / annular ribbons 52 extend out of the upper cover 11), the conductive needle 9 contacts the battery 8 to form a conductive path, and the alarm a sounds an alarm, thereby promptly reminding relevant personnel to pay attention to the insect situation.

[0073] Figure 4 This is a schematic diagram of the design of the visually conspicuous part of an ant monitoring device according to the present application. Figure 4 As shown in the figure (the conductive circuit c is omitted), the upper cover 11 has a guide tube 111, and the outer peripheral surface of the guide tube 111 is provided with an annular color band 52 along the circumferential direction as a visually striking part 5. The rod 4 has a rod body 41 passing through the guide tube 111 and a crown body 42 for covering the annular color band 52. The rod 4 has a third state (not shown) in which the upper cover 11 is extended when the bait is heavy and the annular color band 52 is covered, and a fourth state (not shown) in which the upper cover 11 is extended when the bait is light and the annular color band 52 is exposed. Figure 4 For the description of the annular color band, please refer to the previous text and will not be repeated here.

[0074] Optionally, in an implementation of this embodiment, a limiter (not shown) for limiting the maximum displacement of the rod 4 can be provided at a position of the rod 4 opposite to the inner side of the upper cover 11, thereby limiting the crown 42 to always cover the opening of the guide tube 111 regardless of how the rod 4 moves. With this design, the influence of rainy days on the bait and the effectiveness of the device can be avoided.

[0075] Those skilled in the art should understand that the various designs of the visually striking parts mentioned in different embodiments of the present application can be flexibly and reasonably combined with other embodiments, for example, combined with the alarm mechanism in other embodiments, which all fall within the protection scope of the present invention.

[0076] In general, the ant monitoring equipment provided in each embodiment of the present application has low maintenance cost and high reuse value, and only the bait needs to be replaced. The equipment causes little damage to the dam, and rainwater scouring the dam will not cause soil erosion. The equipment is simple and easy to install, has obvious monitoring effect, and is easy to identify. The practicality of the equipment will greatly reduce government funding and has strong preventive effect.

[0077] This product adopts the method of "fixed-point monitoring and centralized killing" to replace the traditional "full spray and wide killing" control method, which will greatly reduce pesticide residues and water pollution in agriculture, forestry, embankments, construction projects, etc. In addition, it will greatly save termite control costs and improve control effects.

[0078] Exemplary construction plan: The points of the dam are divided into the water-facing slope, the top of the dam, and the outer slope of the dam. The points of the water-facing slope are arranged in a single row at 50 cm above the highest water level, with a point spacing of 25 meters; the points of the top of the dam are arranged in a single row, 50 cm outside the inner dam shoulder, with a point spacing of 25 meters; the points of the outer slope of the dam are double rows, with a row spacing of 2 / 3 of the dam length, and a point spacing of 25 meters; the points of the water-facing slope, the top of the dam, and the outer slope of the dam should be arranged in a plum blossom shape.

[0079] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
