Description

Technical Field

[0001] The utility model relates to the technical field of insect trapping devices, in particular to a termite monitoring device. Background Art

[0002] Termites are one of the five major pests in the world. The damage caused by termites to objects is carried out secretly and is not easily discovered by people. The surface of the damaged object seems intact, but it is full of holes inside. Once discovered, serious losses have already been caused. The food of termites is very extensive. All substances containing cellulose are their food, such as building structures, stored materials, cotton and linen products, books, and railway sleepers. At the same time, the formic acid secreted in their bodies can also corrode steel bars and denature concrete. Therefore, termites will damage river embankments and reservoir dams. They build nests densely in the dams, and the termite galleries extend in all directions. Some termite galleries even penetrate the inner and outer slopes of the dams. When the water level rises during the flood season, pipe leakage accidents often occur, and even cause major hazards such as dike breaches.

[0003] In order to prevent termites, it is necessary to monitor termites. Currently, a termite monitoring device is inserted into the dam soil. There is a bait rod in the termite monitoring device. The bait rod is used to attract termites to bite. By obtaining the information that termites enter the termite monitoring device to bite the bait rod, termite monitoring is realized. When termites are detected, an alarm is given to facilitate subsequent timely termite killing.

[0004] There is a form of termite monitoring device that uses a camera to observe termites. This kind of termite monitoring device includes a housing. The main part of the housing is a cylinder and the bottom is a pointed structure for easy insertion into the soil. There is a bait rod in the housing. The bait rod is fixed to the bottom of the housing. The extending direction of the bait rod is the same as the axis direction of the housing. There are a plurality of entrances for termites to enter the housing distributed on the circumferential side wall of the housing. There is a monitoring component at the top of the housing. The monitoring component includes a camera and a lighting lamp. The camera and the lighting lamp are arranged adjacent to each other. The camera and the lighting lamp are located obliquely above the bait rod. When it is necessary to observe whether there are termites on the bait rod, the lighting lamp and the camera are turned on, and an image of the surface of the bait rod is taken and the image is recognized to determine whether there are termites invading.

[0005] When the lighting lamp and the camera at the top of the housing cooperate to take pictures of the lower bait rod, since the upper end of the bait rod is closer to the lighting lamp and the camera and the lower end is farther from the lighting lamp and the camera, when the lighting lamp flashes, the lighting intensity at the upper end of the bait rod is greater and the lighting intensity at the lower end is weaker, which affects the exposure effect of the captured image, resulting in poor photo quality and difficult to accurately identify termites through the image. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a termite monitoring device, so as to solve the problem that when the existing termite monitoring device takes pictures of the bait rod through the cooperation of the illuminating lamp and the camera on the top of its housing, the uneven illumination of the bait rod by the illuminating lamp easily leads to poor image shooting quality and affects the identification of termites.

[0007] The technical solution of the termite monitoring device of the present utility model is as follows:

[0008] A termite monitoring device includes a housing and a bait rod arranged inside the housing. An illuminating lamp and a camera for collecting the surface image of the bait rod are provided on the top of the housing. The top end and the bottom end of the bait rod are within the shooting range of the camera. The illuminating lamp is inclined relative to the bait rod. Defining the projection direction perpendicular to the extending direction of the illuminating lamp center line and the extending direction of the bait rod, the extension line of the illuminating lamp center line intersects with the projection of the bait rod in the projection direction, and the intersection point is closer to the bottom end of the bait rod than to the top end of the bait rod.

[0009] Further, the camera is inclined relative to the bait rod. The extension line of the camera center line intersects with the projection of the bait rod in the projection direction, and the intersection point is farther from the bottom end of the bait rod than to the top end of the bait rod.

[0010] Further, the distance between the camera and the center line of the housing is less than the distance between the illuminating lamp and the center line of the housing.

[0011] Further, an installation cavity for the shooting component is provided on the top of the housing, and both the camera and the illuminating lamp are installed in the installation cavity for the shooting component.

[0012] Further, the housing includes a main housing and a top housing. The top housing is arranged on the top of the housing. The bait rod is arranged inside the main housing. The top housing has a bottom wall that separates the internal space of the top housing from the internal space of the main housing. A concave cavity is provided on the bottom wall of the top housing. The installation cavity for the shooting component is formed by the concave cavity. The concave cavity is provided with a window for the camera and the illuminating lamp to collect the surface image of the bait rod.

[0013] Further, an inclined camera installation surface and an illuminating lamp installation surface are provided at the bottom of the concave cavity. The depth of the part of the concave cavity where the illuminating lamp installation surface is located is greater than the depth of the part where the camera installation surface is located.

[0014] Further, the camera and the illuminating lamp are located on one side of the center line of the housing, the bait rod is located on the other side of the housing away from the camera and the illuminating lamp, and the camera and the illuminating lamp are located obliquely above the bait rod.

[0015] Further, there are more than three bait rods, and each bait rod is arranged at intervals along the circumferential direction around the center line of the housing.

[0016] Furthermore, the bait rod has a front side and a back side. The front side is connected to the back side and forms the outer peripheral surface of the bait rod. The front side is used to face the camera and the lighting lamp, and the back side faces away from the camera and the lighting lamp.

[0017] Furthermore, the cross-section of the bait rod is trapezoidal. The front side includes the side surfaces of the bait rod where the two waists of the trapezoid are located and the side surface of the bait rod where the upper base is located.

[0018] Beneficial effects: Based on the termite monitoring device in the prior art, the present utility model makes element changes, such that the lighting lamp is inclined relative to the bait rod and the extension line of the center line of the lighting lamp intersects with the projection of the bait rod in the projection direction, and the distance from the intersection point to the bottom end of the bait rod is less than the distance to the top end of the bait rod. That is, the central illumination area of the lighting lamp irradiates on the part of the bait rod close to the bottom end and far from the top end. By using the stronger light in the central illumination area of the lighting lamp, the illumination intensity of the bottom part of the bait rod far from the lighting lamp is increased, which is beneficial to the illumination uniformity in the top-bottom direction of the bait rod, and can have a better shooting effect when the camera captures images, which is beneficial to accurately identifying termites through the images.

A support plate 4 is arranged in the main shell 3, a bait rod 5 is fixed on the support plate 4, and an entrance 31 for termites to enter the housing to bite the bait rod 5 is arranged on the main shell 3. The top cover 1 and the top shell 2 form the top of the housing, the top cover 1 and the top shell 2 enclose a sealed space 6 in the upper part of the housing, the top shell 2 and the main shell 3 enclose an open space 10 in the lower part of the housing, the bait rod 5 is located in the open space 10, the sealed space 6 includes the space inside the installation cavity 7 for the shooting component, and a camera 8 and a lighting lamp 9 for collecting the surface image of the bait rod 5 are arranged in the installation cavity 7 for the shooting component. The top end and the bottom end of the bait rod 5 are within the shooting range of the camera 8. The lighting lamp 9 is arranged obliquely relative to the bait rod 5, and the illumination intensity of the lighting lamp 9 gradually decreases from the center to the periphery. Define the projection direction perpendicular to the extension direction of the center line of the lighting lamp 9 and the extension direction of the bait rod 5. The extension line 91 of the center line of the lighting lamp intersects with the projection of the bait rod 5 in the projection direction, and the distance between the intersection point and the bottom end of the bait rod 5 is less than the distance between the intersection point and the top end of the bait rod 5, that is, the central illumination area of the lighting lamp 9 irradiates on the part of the bait rod 5 close to the bottom end and far from the top end. Utilize the relatively strong light in the central illumination area of the lighting lamp 9 to increase the illumination intensity of the bottom part of the bait rod 5 far from the lighting lamp 9, which is beneficial to the illumination uniformity in the top-bottom direction of the bait rod 5, and can have a better shooting effect when the camera 8 collects images, which is beneficial to accurately identifying termites through the surface image of the bait rod 5 collected.

[0031] The main housing 3 is of a cylindrical structure, and its bottom is a conical bottom which forms the bottom of the housing. The support plate 4 is arranged inside the main housing 3 near the bottom. Taking the extending direction of the central axis of the main housing 3 as the up and down direction, the conical bottom of the main housing 3 faces downward. A plurality of inlets 31 are provided on the cylindrical wall of the main housing 3 above the support plate 4. The inlets 31 are arranged in multiple columns along the circumferential direction of the main housing 3, and multiple inlets are arranged in each column along the up and down direction. The bait rod 5 inside the main housing 3 is vertically arranged, and the extending direction of the bait rod 5 is the up and down direction, that is, the length direction of the bait rod 5. The top end of the bait rod 5 is the upper end, and the bottom end is the lower end. The top-bottom direction of the bait rod is the up and down direction. The lower end of the bait rod 5 is fixed on the support plate 4, and the upper end of the bait rod 5 is lower than the upper end opening of the main housing 3. The top housing 2 is connected to the upper end opening of the main housing 3, and the top cover 1 is connected to the upper end of the top housing 2. The top cover 1 is threadedly connected to the top housing 2, and a sealing ring is provided at the connection. The top cover 1, the top housing 2 and the main housing 3 are coaxially arranged, and the central axes of the three together form a housing central axis extending up and down. The bait rod 5 is arranged on the left side of the housing central axis, and the camera 8 and the lighting lamp 9 are arranged on the right side of the housing central axis. The camera 8 and the lighting lamp 9 are arranged obliquely above the bait rod 5 so as to facilitate observing the surface of the bait rod 5.

[0032] Both the camera 8 and the lighting lamp 9 are obliquely arranged relative to the bait rod 5, and the inclination angles of the camera 8 and the lighting lamp 9 are different. The central axis of the camera 8, the central axis of the lighting lamp 9 and the housing central axis are coplanar, and the normal direction of this plane is the front and back direction. The front and back direction constitutes the projection direction. The extension line 81 of the camera central axis intersects with the projection of the bait rod 5 in the projection direction, and the distance from the intersection to the bottom end of the bait rod 5 is greater than the distance from the intersection to the top end of the bait rod 5, so as to ensure the shooting angle of the camera 8. The projection of the bait rod 5 in the projection direction is closest to the contour line formed by the projections of the camera 8 and the lighting lamp 9, and the intersection of the contour line and the corresponding extension line is formed. The distance between the camera 8 and the housing central axis is less than the distance between the lighting lamp 9 and the housing central axis, which is convenient for arranging the camera 8 and the lighting lamp 9, with a compact structure and space saving.

[0033] Combined Figure 3 、 Figure 4, the top shell 2 has a bottom wall that separates the inner space of the top shell 2 from the inner space of the main shell 3, that is, the bottom wall of the top shell 2 separates the sealed space 6 and the open space 10. A main board, a video processing board, an antenna, and a battery are also installed in the sealed space 6. Near the edge of the bottom wall of the top shell 2, there is a downwardly recessed cavity, which forms a shooting component mounting cavity 7. The camera 8 and the lighting lamp 9 are both installed in the shooting component mounting cavity 7. The shooting component mounting cavity 7 is provided with a window for the camera 8 and the lighting lamp 9 to collect the surface image of the bait rod 5. The concave cavity on the bottom wall of the main shell 3 facilitates the sealing of the camera 8 and the lighting lamp 9, which is beneficial to protecting the camera 8 and the lighting lamp 9. The part of the main shell 3 that forms the shooting component mounting cavity 7 is recessed relative to the inner wall surface of the bottom wall of the main shell 3 and protrudes relative to the outer wall surface. The bottom of the shooting component mounting cavity 7 is provided with an inclined camera mounting surface 71 and a lighting lamp mounting surface 72. The depth of the part of the shooting component mounting cavity 7 where the lighting lamp mounting surface 72 is located is greater than the depth of the part where the camera mounting surface 71 is located, so that the depth of the camera mounting hole 73 on the camera mounting surface 71 is greater than the depth of the lighting lamp mounting hole 74 on the lighting lamp mounting surface 72, adapting to the sizes of the camera 8 and the lighting lamp 9. The orifices of the camera mounting hole 73 and the lighting lamp mounting hole 74 that are far from the corresponding mounting surfaces form a window, and a transparent glass sheet is provided at the window to avoid blocking the field of view of the camera 8 and the light of the lighting lamp 9 while ensuring sealing.

[0034] The camera 8 and the lighting lamp 9 have different inclination angles. Correspondingly, the camera mounting surface 71 and the lighting lamp mounting surface 72 have different inclination angles. The included angle between the lighting lamp mounting surface 72 and the horizontal plane is smaller than the included angle between the camera mounting surface 71 and the horizontal plane, ensuring the installation positions of the camera 8 and the lighting lamp 9. The lighting lamp 9 is located on one side of the center line of the housing, the bait rod 5 is located on the other side of the housing away from the camera 8 and the lighting lamp 9, and the camera 8 and the lighting lamp 9 are located obliquely above the bait rod 5, which is beneficial to ensuring the shooting angle and improving the shooting quality.

[0035] Combined Figure 5 , Figure 6 , Figure 7 , Figure 8 , in this embodiment, there are four bait rods 5, and the bait rods 5 are arranged at intervals along the circumferential direction around the center line of the housing. Each bait rod 5 can be close to the side wall of the main shell 3 to facilitate attracting termites. The support plate 4 is provided with four fixed connection holes 41 corresponding to the four bait rods 5 respectively. The end face of the bottom end of the bait rod 5 is provided with connection blind holes corresponding to the fixed connection holes 41 to fix the bait rod 5 on the support plate 4 through screws. The support plate 4 is provided with through holes 42 of different sizes, and the tapered bottom of the main shell 3 is provided with a through hole to facilitate the termites to gnaw and the materials to fall and the excrement to drop. The support plate 4 is provided with a positioning groove 43, and the tapered bottom of the main shell 3 is provided with support ribs and positioning ribs. The support plate 4 is supported on the support ribs and the positioning ribs are inserted into the positioning groove 43 to position the support plate 4.

[0036] The cross-section of the bait rod 5 is trapezoidal and is an isosceles trapezoid. The isosceles trapezoid includes an upper base, a lower base and two waists. Correspondingly, the bait rod 5 has four side surfaces except for the two end surfaces. The four side surfaces respectively correspond to the upper base, the lower base and the two waists of the trapezoid. Among them, the side surface of the bait rod 5 where the upper base is located faces the center line of the housing. The side surface where the lower base is located faces away from the center line of the housing and forms the back surface of the bait rod 5. The side surface where the upper base is located and the side surfaces where the two waists are located together form the front surface of the bait rod 5. The front surface is connected to the back surface and forms the outer peripheral surface of the bait rod 5. The front surface is used to face the camera 8 and the lighting lamp 9, and the back surface faces away from the camera 8 and the lighting lamp 9, so that the camera 8 can capture a larger area of the surface of the bait rod 5, which is beneficial to accurately judge whether there are termites invading. The trapezoidal bait rod 5 is convenient to manufacture. The camera 8 and the lighting lamp 9 obliquely above can capture three side surfaces of the bait rod 5, obtaining a better monitoring and photographing effect. The front surface of the bait rod 5 is covered by the lighting lamp and the camera, which is convenient for collecting termite images.

[0037] The bait rod 5 is made of pine wood that termites like to eat. A filler hole 51 extending up and down is provided in the center of the bait rod 5. Fine sand 14 is filled in the filler hole 51. An induction block 13 is provided above the fine sand 14 in the filler hole 51. A sensor 15 is attached to the back surface of the bait rod 5. Termites like to bite the front surface of the bait rod 5. The sensor 15 is connected to the circuit board in the upper sealed space 6 through a wire 12. A sealing structure is provided at the part where the wire 12 passes through the top shell 2. When termites bite through the bait rod 5, the fine sand 14 leaks out, the height of the fine sand 14 drops, the induction block 13 moves down accordingly, and the sensor 15 senses the position change of the induction block 13, thereby obtaining termite invasion information and giving an alarm. This termite monitoring device can give an alarm by the cooperation of the sensor 15 and the induction block 13, and can also give an alarm by collecting images through the camera 8 and performing image recognition and judgment.

[0038] In order to ensure the position of the bait rod 5, a limit card slot 52 is provided on the upper end surface of the bait rod 5. The limit card slot 52 penetrates the side surfaces where the two waists of the trapezoidal cross-section of the bait rod 5 are located. The limit card slot 52 extends along an arc. Each bait rod 5 is positioned by a positioning plug 11. The positioning plug 11 includes a part pressing on the upper end surface of each bait rod 5, a part inserted into the upper end of the filler hole 51, and a part inserted into the limit card slot 52. The part of the positioning plug 11 inserted into the upper end of the filler hole 51 and the part inserted into the limit card slot 52 are connected. The positioning plug 11 plays a role in preventing the bait rod 5 from rotating.

[0039] In other embodiments, the inclination angle of the camera relative to the horizontal plane can also be the same as the inclination angle of the lighting lamp relative to the horizontal plane.

[0040] In other embodiments, the distance between the camera and the center line of the housing can also be greater than the distance between the lighting lamp and the center line of the housing, and the lighting lamp is arranged obliquely above the camera.

[0041] In other embodiments, the camera and the lighting lamp can also be installed on the lower side of the bottom wall of the top shell. The lower side of the bottom wall of the top shell is provided with corresponding mounting bosses, and the mounting bosses are provided with corresponding mounting surfaces for installing the camera and the lighting lamp.

[0042] In other embodiments, the bait rod can also be provided as one and located at the center of the housing.

[0043] In other embodiments, the bait rods can also be arranged at intervals in a straight line direction.

[0044] In other embodiments, the bait rods can also be provided as three.

[0045] In other embodiments, the cross-section of the bait rod can also be semi-circular, with the front surface of the bait rod being an arc surface and the back surface being a flat surface.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
