Description

Technical Field

[0001] The invention relates to the technical field of noise monitoring, and in particular to a noise pollution law enforcement and evidence collection robot. Background Art

[0002] Any sound that disturbs people's rest, study and work, as well as the sound you want to hear, that is, unwanted sound, is collectively called noise. When noise has adverse effects on people and the surrounding environment, it forms noise pollution. Its main sources include traffic noise, industrial noise, construction noise and social noise. Noise pollution monitoring is a monitoring activity for the sounds and sound sources that disturb people's study, work and life.

[0003] There is often a lot of dust in industrial production areas, construction sites, and transportation sections. The noise pollution law enforcement evidence collection robot used in such areas will inevitably have dust on its lens and other key components, affecting the accurate shooting of the noise monitoring location. To this end, we propose a noise pollution law enforcement evidence collection robot.

[0004] When we consider the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing ones on the market, and even if they can be solved, they need to be solved through the cooperation of external tools, which makes it impossible to achieve the desired effect. Therefore, we propose a noise pollution law enforcement evidence collection robot. Summary of the invention

[0005] The purpose of the present invention is to provide a noise pollution law enforcement evidence collection robot to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a noise pollution law enforcement evidence collection robot, comprising a main body mechanism, the main body mechanism comprising a mobile base, a display screen is installed on the mobile base, a noise transmitter is installed on the mobile base, a control module is installed on the mobile base, a data transmission module is installed on the mobile base, a camera module is installed on the mobile base, and a dust cleaning mechanism is arranged on the top of the mobile base;

[0007] The dust cleaning mechanism includes a wiping unit, which is arranged on the top of the mobile base and is used to wipe dust off the surface of the camera module;

[0008] The dust cleaning mechanism further includes a brushing unit, which is disposed above the movable base and is used in conjunction with the wiping unit to brush away dust wiped off the surface of the camera module;

[0009] The brushing unit is provided with a squeezing mechanism, and the squeezing mechanism is used in conjunction with the brushing unit to enhance the dust brushing effect.

[0010] Preferably, the wiping unit includes an installation box, which is located above the movable base, a servo motor is fixedly connected to the interior of the installation box, the output shaft of the servo motor is fixedly connected to the first bevel gear, a threaded rod is rotatably connected to the interior of the installation box, the second bevel gear is fixedly connected to the threaded rod, a movable cylinder is threadedly connected to the outer side of the threaded rod, a movable block is fixedly connected to the outer side of the movable cylinder, connecting plates are fixedly connected to both sides of the movable block, a servo motor is fixedly connected to one side of the connecting plate, a rotating rod is fixedly connected to the output shaft of the servo motor, a mounting plate is fixedly connected to one side of the rotating rod, and a wiping block is fixedly connected to one side of the mounting plate.

[0011] Through the above technical scheme, the servo motor is started to drive the first bevel gear to rotate forward, and the threaded rod is driven to rotate by the second bevel gear meshing with the first bevel gear. Under the transmission of the movable cylinder, the movable block and the connecting plate, the mounting plate is pushed out of the mounting box, and then the servo motor is started to rotate forward, so that the wiper on one side of the mounting plate rotates on the glass sheet on the surface of the camera module to wipe off the dust on its surface, thereby preventing the camera module from being stained with dust in industrial production areas, construction sites, and transportation sections, etc., which affects the accurate shooting of the noise monitoring position.

[0012] Preferably, a cushion block is fixedly connected to one side of the servo motor, and the other side of the cushion block is fixedly connected to the inner wall of the installation box, the first bevel gear is meshed with the second bevel gear, the inner side of the movable cylinder is provided with an internal thread matched with the threaded rod, the rotating rod movably passes through the connecting plate, the top of the movable block is fixedly connected with a first limit block, and the inner top wall of the installation box is provided with a first limit groove matched with the moving trajectory of the first limit block.

[0013] Through the above technical solution, since the first bevel gear is meshed with the second bevel gear, the first bevel gear can be driven to rotate by the servo motor, and the threaded rod is rotated through the transmission between the first bevel gear and the second bevel gear, so as to adjust the position of the mounting plate. At the same time, with the cooperation of the first limit block and the first limit groove, the movable cylinder and the movable block can be prevented from rotating together with the threaded rod, thereby ensuring that the mounting plate can move in a straight line.

[0014] Preferably, a second limit block is fixedly connected to one side of the connecting plate, second limit grooves adapted to the moving trajectory of the second limit block are provided on the left and right sides of the inner wall of the installation box, a movable through hole adapted to the installation plate is provided on the front side wall of the installation box, a support rod is fixedly connected to the bottom of the installation box, and the bottom of the support rod is fixedly connected to the top of the movable base.

[0015] Through the above technical scheme, with the coordinated use of the second limit block and the second limit groove, the moving direction of the connecting plate and the mounting plate can be further limited. By opening a movable through hole on the front side wall of the mounting box, it can be ensured that the mounting plate can freely enter and exit the mounting box without colliding with it. Under the action of the support rod, the mounting box and the camera module can be supported to facilitate shooting by the camera module.

[0016] Preferably, camera modules are fixedly connected to both sides of the installation box, a glass sheet is fixedly connected to the surface of the camera module, and a microfiber cloth is fixedly connected to the surface of the cleaning block on one side close to the glass sheet.

[0017] Through the above technical solution, the glass sheet on the surface of the camera module will not only not affect the shooting of the camera module, but also play a protective role for the camera module. The microfiber cloth is made of microfiber, has super water absorption and oil absorption, can easily absorb dust without leaving any fibers, and its material is soft and will not scratch the surface of the glass sheet.

[0018] Preferably, the brushing unit includes an electric push rod, which is fixedly connected to the inner bottom wall of the installation box, and the output end of the electric push rod is fixedly connected to a cross plate, one side of the cross plate is fixedly connected to a connecting block, one side of the connecting block is fixedly connected to a mounting frame, the interior of the mounting frame is movably connected to a movable plate, and one side of the movable plate is fixedly connected to bristles.

[0019] Through the above technical solution, the electric push rod is started to continuously extend and contract its output end. Under the transmission of the cross plate and the connecting block, the mounting frame is reciprocated up and down along the direction of the third limit groove, and the movable plate and the brush also reciprocate up and down accordingly, and the dust attached to the wiping block is brushed off by the brush.

[0020] Preferably, the number of the connecting blocks is two and they are symmetrically distributed, the length of the mounting frame is smaller than the length of the wiping block, the moving stroke of the transverse plate is equal to the difference between the moving plate and the wiping block, and the bristles are located on the side close to the wiping block.

[0021] With the above technical solution, since the moving stroke of the horizontal plate is equal to the difference between the moving plate and the wiping block, the moving plate can fully cover the wiping block when it reciprocates up and down, thereby brushing away the dust.

[0022] Preferably, the cross plate is fixedly connected to both sides with a third limit block, the inner wall of the installation box is provided with a third limit groove compatible with the moving trajectory of the third limit block on the left and right sides, the movable plate is fixedly connected to the fourth limit block on the upper and lower sides, and the inner wall of the installation frame is provided with a fourth limit groove compatible with the moving trajectory of the fourth limit block on the upper and lower sides.

[0023] Through the above technical scheme, with the coordinated use of the third limit block and the third limit groove, the moving direction and moving distance of the horizontal plate and the mounting frame are guaranteed. With the coordinated use of the fourth limit block and the fourth limit groove, the moving direction and moving distance of the moving plate and the bristles are guaranteed.

[0024] Preferably, the extrusion mechanism includes a mounting cylinder, which is fixedly connected to one side of the mounting frame, a slider is slidably connected to the inside of the mounting cylinder, an extrusion spring is fixedly connected between the slider and the inner wall of the mounting cylinder, a pressure rod is fixedly connected to the other side of the slider, and a sliding groove matching the moving trajectory of the slider is opened inside the mounting cylinder.

[0025] Through the above technical solution, under the elastic force of the extrusion spring, the slider moves along the slide groove inside the installation tube, and then the pressure rod also moves accordingly, thereby achieving fine adjustment of the position of the moving plate.

[0026] Preferably, the mounting frame is provided with two mounting tubes symmetrically distributed on both sides of the connecting block, the extrusion spring is always in a compressed state, one side of the pressure rod passes through the mounting tube and extends to the interior of the mounting frame and is fixedly connected to the movable plate, and an ash dropping hole is provided on the inner bottom wall of the mounting box.

[0027] Through the above technical solution, since the extrusion spring is always in a compressed state, the extrusion spring always exerts an extrusion force on the slider, so that the slider moves along the slide groove in the mounting tube, pushing the pressure rod to move outside the mounting tube, thereby causing the movable plate and bristles fixedly connected to the pressure rod to be pressed against the wiping block, preventing the bristles from being separated from the wiping block, thereby enhancing the dust brushing effect.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention sets a wiping unit, and a servo motor drives the first bevel gear to rotate forward, and drives the threaded rod to rotate through the second bevel gear meshing with the first bevel gear. Driven by the movable cylinder, the movable block and the connecting plate, the mounting plate is pushed out of the mounting box, and then the servo motor is started to rotate forward, and the wiping block on the mounting plate is rotated and wiped on the glass sheet on the surface of the camera module, so as to prevent the camera module from being stained with dust in industrial production areas, construction sites, and transportation sections, etc., which affects the accurate shooting of the noise monitoring position.

[0030] 2. The present invention is capable of brushing off the dust on the wiping block by providing a brushing unit, thereby preventing dust from remaining on the surface of the wiping block when the wiping block wipes the glass sheet on the surface of the camera module again, thereby causing the glass sheet of the camera module to be not wiped cleanly. This further prevents the camera module from being stained with dust in industrial production areas, construction sites, transportation sections, etc., which affects the accurate shooting of the noise monitoring position.

[0031] 3. The present invention sets up a squeezing mechanism. Since the slide groove is always in a compressed state, the slide groove always exerts a squeezing force on the slider, so that the slider moves along the pressure rod to the side close to the installation frame. The moving plate in the installation frame is pushed by the squeezing spring, so that the bristles on the moving plate can be pressed against the surface of the wiping block, thereby enhancing the dust brushing effect.

[0052] Embodiment 2

[0053] See also Figure 1-10The present invention provides a technical solution: a noise pollution law enforcement evidence collection robot. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0054] As a further limitation of the dust cleaning mechanism 2 of the present invention, the dust cleaning mechanism 2 further includes a brushing unit 22, which is disposed above the mobile base 11, and the brushing unit 22 is used in conjunction with the wiping unit 21, and the brushing unit 22 is used to brush away the dust wiped off the surface of the camera module 16;

[0055] The brushing unit 22 includes an electric push rod 2201, which is fixedly connected to the inner bottom wall of the installation box 2101. The output end of the electric push rod 2201 is fixedly connected to a transverse plate 2202, one side of the transverse plate 2202 is fixedly connected to a connecting block 2203, one side of the connecting block 2203 is fixedly connected to a mounting frame 2204, the interior of the mounting frame 2204 is movably connected to a moving plate 2205, one side of the moving plate 2205 is fixedly connected to a brush 2206, and the electric push rod 2201 is started to continuously extend and contract its output end, and under the transmission of the transverse plate 2202 and the connecting block 2203, the mounting frame 2204 is reciprocated up and down along the direction of the third limiting groove 2208, and the moving plate 2205 and the brush 2206 are also reciprocated up and down, and the dust attached to the wiping block 2112 is brushed off by the brush 2206;

The moving stroke of the horizontal plate 2202 is equal to the difference between the moving plate 2205 and the wiping block 2112. The bristles 2206 are located on the side close to the wiping block 2112. Since the moving stroke of the horizontal plate 2202 is equal to the difference between the moving plate 2205 and the wiping block 2112, the moving plate 2205 can fully cover the wiping block 2112 when it reciprocates up and down, thereby achieving dust removal.

[0059] Embodiment 3

[0060] See also Figure 1-10 The present invention provides a technical solution: a noise pollution law enforcement evidence collection robot. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0061] As a further limitation of the dust cleaning mechanism 2 of the present invention, a pressing mechanism 3 is provided on the brushing unit 22, and the pressing mechanism 3 is used in conjunction with the brushing unit 22 to enhance the dust brushing effect;

[0062] The squeezing mechanism 3 includes a mounting cylinder 301, which is fixedly connected to one side of the mounting frame 2204. A slider 302 is slidably connected inside the mounting cylinder 301. A squeezing spring 303 is fixedly connected between the slider 302 and the inner wall of the mounting cylinder 301. A pressing rod 304 is fixedly connected to the other side of the slider 302. A sliding groove 305 adapted to the moving track of the slider 302 is provided inside the mounting cylinder 301. Under the elastic force of the squeezing spring 303, the slider 302 moves inside the mounting cylinder 301 along the sliding groove 305, and then the pressing rod 304 also moves accordingly, so as to achieve fine adjustment of the position of the moving plate 2205.

[0063] Two mounting tubes 301 are installed on the mounting frame 2204 and are symmetrically distributed on both sides of the connecting block 2203. The squeezing spring 303 is always in a compressed state. One side of the pressure rod 304 passes through the mounting tube 301 and extends to the interior of the mounting frame 2204 and is fixedly connected to the movable plate 2205. A dust dropping hole 306 is provided on the inner bottom wall of the mounting box 2101. Since the squeezing spring 303 is always in a compressed state, the squeezing spring 303 always exerts a squeezing force on the slider 302, so that the slider 302 moves along the slide groove 305 in the mounting tube 301, pushing the pressure rod 304 to move out of the mounting tube 301, thereby making the movable plate 2205 and the bristles 2206 fixedly connected to the pressure rod 304 press against the wiping block 2112 all the time, preventing the bristles 2206 from detaching from the wiping block 2112, thereby enhancing the dust brushing effect.

[0064] The specific implementation of this embodiment is as follows: when the bristles 2206 are used to brush dust off the surface of the wiper block 2112, under the elastic force of the extrusion spring 303, the slider 302 pushes the pressure rod 304 toward the outside of the mounting tube 301 along the slide groove 305, and under the transmission of the pressure rod 304, the movable plate 2205 and the bristles 2206 are pressed toward the wiper block 2112, so that the bristles 2206 are always pressed against the surface of the wiper block 2112, preventing the bristles 2206 from separating from the wiper block 2112, thereby enhancing the dust brushing effect.

[0065] The working principle of the present invention is as follows: first, a command is sent to the control module 14 through the remote control center to make the mobile base 11 move, and the sound sensor such as the microphone built into the noise transmitter 13 captures the sound wave and converts it into a point model. After the internal signal processing circuit amplifies, filters and digitally processes the electrical signal, the parameters such as the intensity and frequency of the noise are obtained and displayed on the display screen 12. When the noise intensity exceeds a preset threshold, the noise transmitter 13 generates a trigger signal and sends the signal to the control module 14. After receiving the trigger signal, the control module 14 immediately sends a shooting command to the camera module 16, captures the image information in the current environment through the camera module 16, and transmits the image information and the noise data obtained by the noise transmitter 13 to the remote control center through the data transmission module 15. The remote control center stores the received image information and noise data in a database, and then displays and analyzes the data.
