TECHNICAL FIELD

[0001] The present application belongs to the technical field of pest detection, and particularly relates to a sound measuring device for detecting pests. BACKGROUND

[0002] If tree diseases and insect pests are not treated in time, the pests will gradually spread, and after a long time, the entire forest land will be greatly damaged, and the trees with diseases and insect pests need to be treated. For the diseases and insect pests inside the trees, spraying medicine on the surface cannot achieve the effect of pest control. Therefore, it is necessary to find the insect hole and then drill and inject medicine, so it is necessary to detect pests, that is, to detect insect pests.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1-8 As shown;

[0040] A sound-measuring device for detecting pests includes a sound meter body 1, a wire 2 installed on one side of the surface of the sound meter body 1, and a connecting seat 31 fixedly disposed at one end of the wire 2 away from the sound meter body 1. A cover 3 is fixedly sleeved on the surface of the wire 2 and outside the connecting seat 31. The connecting seat 31 is slidably installed in the inner cavity of the cover 3, and a sound-measuring terminal 5 is fixedly disposed on one side of the surface of the connecting seat 31.

[0041] In this implementation plan: by holding the shell 3 and pressing the sound measuring terminal 5 against the surface of the tree, the tree is made to generate sound frequency by tapping it with a tool, and the sound measuring terminal 5 receives the sound frequency. Through multiple tests, the approximate location of the worm hole is finally determined, and then the insect repellent operation is carried out.

[0042] It should be noted that the sound meter body 1 contains a sound sensor, a microprocessor, and a buzzer. The sound sensor collects the sound frequency emitted by the tree after it is hit and inputs the collected sound frequency into the microprocessor. By comparing it with the preset insect sound library in the microprocessor, it can determine whether there is an insect hole in the area. If it is determined that there is no insect hole, a signal is sent to the buzzer to control the buzzer to sound, so as to remind the user that there are no insects in the area.

[0043] It should be noted that all electrical equipment involved in this product is powered by an external power source.

[0044] Based on this, the security monitoring camera bracket also includes a protective component 4 installed on one side of the surface of the housing 3;

[0045] The protective component 4 includes a sleeve plate A42 slidably connected to a through groove A on one side of the surface of the housing 3 and a push plate 41 installed on one side of the surface of the housing 3 and corresponding to the position of the sleeve plate A42. A pressing pad 412 is fixedly provided outside the through hole A at the center of the surface of the push plate 41. A connecting block 411 is fixedly provided inside the pressing pad 412. The side of the connecting block 411 away from the pressing pad 412 is inserted into the sleeve plate A42. A vertical rod 413 is welded to the side of the connecting block 411 inserted into the sleeve plate A42. A pressing block A414 is welded to the end of the vertical rod 413 away from the connecting block 411. Pressing blocks B423 are abutting and connected to both sides of the pressing block A414. An insert block 422 is welded to the side of the pressing block B423 away from the pressing block A414. The side of the insert block 422 extends out of the sleeve plate A42 and abuts against the inner wall of the through groove A of the housing 3.

[0046] In this implementation scheme: In conjunction with the above, the housing 3 is pressed against the surface of the tree, and the push plate 41 is pushed to move the sleeve plate A42 through the connecting block 411. At the same time, the connecting seat 31 is pushed to move the sound measuring terminal 5 closer to or into contact with the tree. At this time, the housing 3 can provide a sealed space for the sound measuring terminal 5, which can reduce external noise and provide sealed protection for the sound measuring terminal 5, reducing the risk of external leakage and damage to the sound measuring terminal 5.

[0047] In an optional embodiment, a slot is provided on the inner wall surface of the through groove A of the housing 3 at the position corresponding to the insertion block 422, and a sleeve plate B421 is slidably connected in the slot. The sleeve plate B421 is slidably sleeved on the surface of the insertion block 422, and one side of the surface of the sleeve plate B421 is welded to the surface of the sleeve plate A42.

[0048] In this embodiment, the sleeve B421 can limit the movement of the sleeve A42 to ensure the stability of the movement of the sleeve A42.

[0049] In an optional embodiment, a spring rod 415 is fixedly provided on the side of the extrusion block A414 away from the upright rod 413. The end of the spring rod 415 away from the extrusion block A414 is fixedly connected to the inner wall of the sleeve plate A42. A sleeve 424 is fixedly provided on the inner wall of the sleeve plate A42 and outside the spring rod 415. The sleeve 424 is slidably connected to the surface of the extrusion block B423 through a slot opened on its surface.

[0050] In this embodiment: In conjunction with the above, while pushing the push plate 41 to move, the pressing pad 412 needs to be pressed to move the squeezing block A414, reducing the movement resistance of the insertion block 422. When it moves to the appropriate position, the pressing pad 412 and the push plate 41 are released. At this time, the spring rod 415 is forced to rebound and push the squeezing block A414 to rise, and the squeezing block A414 pushes the insertion block 422 to move through the squeezing block B423, so that the insertion block 422 abuts against the housing 3, increasing the friction and fixing the sound measuring terminal 5.

[0051] It should be noted that the contact surfaces of the compression block B423 and the spring rod 415 are both designed with bevels to provide motion guidance.

[0052] In an optional embodiment, the surface of the connector 31 is provided with an annular groove outside the sound measuring terminal 5, and an outer cover 432 is fixedly provided in the groove. A horn-shaped corrugated sleeve 431 is fixedly provided on the surface of the outer cover 432 away from the connector 31.

[0053] In this embodiment: In conjunction with the above, when the sound measuring terminal 5 approaches the tree, the corrugated sleeve 431 first contacts the tree and is pushed by force to retract the outer cover 432, which is used to further protect the sound measuring terminal 5 and isolate external noise.

[0054] In an optional embodiment, a housing 45 is further included, which is welded to the surface of the housing 3 and located on one side of the push plate 41. A turntable 451 is rotatably connected inside the housing 45. A connecting rod 47 is slidably sleeved on one side of the surface of the turntable 451 via a mounting shaft. The center of the surface of the connecting rod 47 is rotatably connected to the housing 45 via a rotating shaft A. A turning wheel 48 is installed in the placement groove of the connecting rod 47 extending out of the housing 45.

[0055] In this embodiment: while the turntable 451 is rotated, the turntable 451 can push the connecting rod 47 to swing back and forth through the mounting shaft. At the same time, the connecting rod 47 can drive the striking wheel 48 to strike the tree, assisting people in carrying out sound measurement work.

[0056] In an optional embodiment, a micro motor 46 is fixedly provided on the surface of the turntable 451, and a drive wheel 461 is fixedly provided on the output shaft surface of the micro motor 46 inserted into the housing 45. A driven wheel 452 is driven by tooth meshing on the surface of the drive wheel 461, and the driven wheel 452 is fixedly sleeved on the rotating shaft B surface of the housing 45.

[0057] In this embodiment: When the micro motor 46 is working, the driven wheel 452 can be driven to rotate synchronously by the driving wheel 461, thereby providing power for the movement of the turntable 451. At the same time, the tooth grooves on the surface of the driven wheel 452 are distributed at intervals, so when the micro motor 46 is working, the connecting rod 47 can control the striking wheel 48 to strike the tree at intervals, which is used to assist people in sound measurement work.

[0058] In an optional embodiment, through holes B are provided on both sides of the inner wall of the placement groove of the connecting rod 47, and elastic ropes 481 arranged at four corners are fixedly provided on the inner wall of the through holes B. The end of the elastic rope 481 away from the connecting rod 47 is fixedly connected to the surface of the rotating shaft C of the steering wheel 48.

[0059] In this embodiment: In conjunction with the above, when the tree is struck by the striking wheel 48, the striking wheel 48 is affected by the vibration and causes the elastic ropes 481 at different positions to contract or extend, thereby reducing the impact force on the striking wheel 48. Furthermore, during the time period between the striking wheel 48 and the tree after it separates from the tree and the next contact with the tree, the elastic ropes 481 have sufficient time to control the striking wheel 48 to reset, making it convenient for the next use.

[0060] Furthermore:

[0061] Based on the above: In addition, it also includes fixing components 6 installed on both sides of the surface of the housing 3 and located below the push plate 41;

[0062] The fixing component 6 includes a sleeve 61 hinged to the surface of the housing 3 via a connecting shaft seat and a pull-out plate 62 inserted into the slot of the sleeve 61. A movable plate 63 is slidably connected in a cavity opened on the surface of the pull-out plate 62. A stress spring 66 is fixedly provided on one side of the movable plate 63 inserted into the pull-out plate 62, and the end of the stress spring 66 away from the movable plate 63 is fixedly connected to the inner wall of the pull-out plate 62. A protrusion 64 is adhered to the side of the movable plate 63 away from the stress spring 66.

[0063] In an optional embodiment, a through groove B is provided on the surface of the sleeve 61 at the position corresponding to the pull plate 62, and an opening is provided on the surface of the pull plate 62 at the position of the through groove B. A connecting plate 65 is welded into the opening of the pull plate 62, and an installation block 651 is inserted into the center of the surface of the connecting plate 65. One end of the installation block 651 inserted into the connecting plate 65 is fixedly connected to the surface of the movable plate 63.

[0064] In an optional embodiment, a sleeve 653 is slidably fitted onto the surface of the mounting block 651, and symmetrical grooves are provided on the surface of the mounting block 651 at positions corresponding to the sleeve 653. A slider 654 is slidably connected in the grooves. A spring piece 652 is welded to one side of the surface of the slider 654. The side of the spring piece 652 away from the slider 654 is fixedly connected to the surface of the movable plate 63. A hemispherical block 655 is welded to the center of the surface of the spring piece 652. The hemispherical block 655 is snapped into the slot opened in the inner wall of the through groove of the connecting plate 65.

[0065] In this implementation plan: By pressing the clamp 61, the clamp 61 is rotated to a suitable angle. The pull plate 62 is pulled to move along the clamp 61 to a suitable position and place the clamp 61 on the tree surface, so that the cover 3 contacts the tree. At this time, the clamp 61 is released, and the elastic spring on the surface of the clamp 61 is forced to reset the clamp 61, thus completing the clamping of the tree. The pad 653 is pushed to move, which drives the slider 654 to move. As the slider 654 pulls the spring 652 to extend, the hemispherical block 655 separates from the connecting plate 65. At this time, the stress spring 66 is forced to rebound and push the movable plate 63 to drive the protrusion 64 to contact the tree, thereby increasing the connection strength with the tree, reducing the time people hold the handle, and ensuring work efficiency.

[0066] It should be noted that the spring piece 652 itself is elastic. When the mounting block 651 is pulled to reset, the spring piece 652 rebounds under force and can push the hemispherical block 655 into the slot of the connecting plate 65, thus completing the storage and fixation of the movable plate 63.

[0067] The working principle and usage process of this invention are as follows: By pressing the clamp 61, the clamp 61 is rotated to a suitable angle. The pull plate 62 is pulled to move along the clamp 61 to a suitable position, and the clamp 61 is placed on the surface of the tree, so that the cover 3 contacts the tree. At this time, the clamp 61 is released, and the elastic spring on the surface of the clamp 61 is forced to reset the clamp 61, thus clamping the tree. The pad 653 is pushed to move, which drives the slider 654 to move. As the slider 654 pulls the spring 652 to extend, the hemispherical block 655 separates from the connecting plate 65. At this time, the stress spring 66 is forced to rebound, pushing the movable plate 63 to drive the protrusion 64 to contact the tree. While pushing the push plate 41 to move, the pressing pad 412 needs to be pressed to move the squeezing block A414, reducing the movement resistance of the insert block 422. After moving to a suitable position, the pressing pad 412 and the cover 3 are released. Push plate 41, at this time, spring rod 415 is pushed back by force to push extrusion block A414 to rise, and extrusion block A414 pushes insertion block 422 to move through extrusion block B423, so that insertion block 422 abuts against shell 3, increasing friction and fixing sound measuring terminal 5. When sound measuring terminal 5 approaches tree, corrugated sleeve 431 first contacts tree and is pushed by force to retract outer cover 432, which is used to further protect sound measuring terminal 5 and isolate external noise. When micro motor 46 is working, it can drive driven wheel 452 to rotate synchronously through drive wheel 461, thereby providing power for turntable 451 to move. At the same time, the tooth grooves on the surface of driven wheel 452 are distributed in intervals, so when micro motor 46 is working, connecting rod 47 can control the striking wheel 48 to strike the tree in intervals to assist people in sound measurement work.

[0068] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
