Specific implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Please refer to Figure 1 - Figure 7 , a chemical industrial hanging rail inspection robot with a lens protection function, including a robot body 1 and a pan-tilt camera 2 installed at the bottom of the robot body 1. A transparent cover 3 is provided outside the pan-tilt camera 2. The transparent cover 3 sleeved on the pan-tilt camera 2, and a detachable component is connected between the transparent cover 3 and the robot body 1. A scraping component is connected to the outer wall of one end of the transparent cover 3 away from the robot body 1.

[0025] As Figure 1 - Figure 7 shown, a chemical industrial hanging rail inspection robot with a lens protection function in the present utility model is similar in structure to the existing chemical industrial hanging rail inspection robot. The main improvement point of the present utility model is that it can protect the pan-tilt camera 2 at the bottom of the inspection robot to avoid damage to the pan-tilt camera and affect normal inspection video recording, as Figures 1 to 7As shown in the figure, when the chemical industrial hanging rail inspection robot with a lens protection function in the present utility model is in use, the transparent cover 3 is covered on the pan-tilt camera 2 at the bottom of the robot body 1 and is fixedly installed on the robot body 1 through a detachable component. When the robot body 1 conducts inspection work, the protective cover 3 can protect the internal pan-tilt camera 2, avoiding contact of the pan-tilt camera 2 with collisions, water vapor, dust, corrosive chemical gases, etc., preventing damage to the pan-tilt camera 2, enabling the pan-tilt camera 2 to continuously and stably conduct inspection video recording. When there are sundries affecting light transmission attached to the outer side of the transparent cover 3, the sundries attached to the outer side of the transparent cover 3 can be scraped and cleaned through a scraping component, thereby maintaining the light transmission of the transparent cover 3 and ensuring the imaging effect of the pan-tilt camera 2. The transparent cover 3 is made of a transparent material, enabling the pan-tilt camera 2 to normally conduct inspection video recording.

[0026] As Figure 1 - Figure 4 shown in the figure, the transparent cover 3 is made of high-strength corrosion-resistant glass. Making the transparent cover 3 of high-strength corrosion-resistant glass enables the transparent cover 3 to avoid being corroded by corrosive chemical volatilized gases when used in a chemical plant, and at the same time, the high-strength glass can improve the anti-collision protection of the pan-tilt camera 2.

[0027] As Figure 1 - Figure 7 shown in the figure, the detachable component includes a connection seat 4 and an external threaded pipe 5. The connection seat 4 is fixedly connected to one side of the robot body 1 close to the pan-tilt camera 2. A threaded hole 401 is penetrated and opened on the side of the connection seat 4 away from the robot body 1. The external threaded pipe 5 is threadedly connected to the threaded hole 401. One end of the external threaded pipe 5 away from the robot body 1 is fixedly connected to and communicated with the transparent cover 3. The pan-tilt camera 2 is located inside the external threaded pipe 5 and the transparent cover 3. During long-term use, if problems such as damage or decreased light transmission of the transparent cover 3 affecting the normal operation of the pan-tilt camera 2 occur, it can be detached from the connection seat 4 through the connection between the external threaded pipe 5 and the threaded hole 401, and a new transparent cover 3 and external threaded pipe 5 can be replaced and reinstalled to ensure that the transparent cover 3 can protect the internal pan-tilt camera 2 without affecting the normal inspection operation of the inspection robot. The external threaded pipe 5 and the transparent cover 3 can be integrally formed and are both made of transparent materials.

[0028] As Figure 3 and Figure 4 shown in the figure, a sealing washer 6 is fixedly connected to one end of the external threaded pipe 5 away from the transparent cover 3. The other end of the sealing washer 6 abuts against the bottom of the robot body 1. By installing the sealing washer 6, the sealing effect inside the transparent cover 3 is improved, preventing water vapor, etc. from entering the interior and affecting the normal operation of the pan-tilt camera 2.

[0029] As Figure 1 - Figure 7As shown in the figure, the scraping component includes an arc-shaped scraping strip 7, a connecting rod 8 and a rotating mechanism. The arc-shaped scraping strip 7 is slidably connected to the outer wall of the transparent cover 3. One end of the arc-shaped scraping strip 7 close to the robot body 1 bends away from the transparent cover 3 and is connected with a flipping mechanism. The flipping mechanism is connected to the connecting rod 8, the connecting rod 8 is connected to the rotating mechanism, and the rotating mechanism is connected to the connecting seat 4. When there are sundries attached to the outside of the transparent cover 3, the rotating mechanism drives the connecting rod 8 and the arc-shaped scraping strip 7 to rotate along the outside of the transparent cover 3, and then the sundries attached to the outside of the transparent cover 3 are scraped and cleaned by the arc-shaped scraping strip 7, maintaining the light transmittance of the transparent cover 3 and avoiding affecting the imaging of the pan-tilt camera 2. At the same time, when installing and disassembling the transparent cover 2, the arc-shaped scraping strip 7 can be flipped outward at the bottom of the connecting rod 8 through the flipping mechanism, so as to avoid hindering the installation and disassembly of the transparent cover 3.

[0030] As Figure 7 shown, the flipping mechanism includes two flipping shafts 9 and two torsion springs 10. One end of the connecting rod 8 close to the arc-shaped scraping strip 7 is provided with a flipping groove 801, and flipping holes 802 are opened on both inner walls of the flipping groove 801. The two flipping shafts 9 are respectively fixedly connected to both sides of one end of the arc-shaped scraping strip 7 close to the connecting rod 8, and the two flipping shafts 9 are respectively rotatably connected to the two flipping holes 802. The two torsion springs 10 are respectively sleeved on the two flipping shafts 9, and one ends of the two torsion springs 10 are respectively fixedly connected to the two flipping shafts 9, and the other ends are respectively fixedly connected to the two flipping holes 802. Through the connection between the two flipping shafts 9 and the two flipping holes 802, the arc-shaped scraping strip 7 can be flipped outward at the bottom of the connecting rod 8, so as to avoid the bottom of the arc-shaped scraping strip 7 affecting the disassembly and installation of the transparent cover 3. At the same time, during normal use, through the two torsion springs 10, the arc-shaped scraping strip 7 can always be pressed against the outside of the transparent cover 3, facilitating the scraping and cleaning work on the outside of the transparent cover 3.

[0031] As Figure 1 - Figure 6As shown in the figure, the rotating mechanism includes a T-shaped turntable 11, a driving gear 12 and a driving motor 13. A T-shaped rotating groove 402 is formed on the side of the connecting seat 4 away from the robot body 1. The T-shaped turntable 11 is located in the T-shaped rotating groove 402 and is rotatably connected to the T-shaped rotating groove 402. The smaller end of the T-shaped turntable 11 passes through the T-shaped rotating groove 402 and is fixedly connected to the end of the connecting rod 8 away from the arc-shaped scraping strip 7. A plurality of tooth grooves 101 are formed on the outer side wall of the larger end of the T-shaped turntable 11. A connecting hole 403 is formed through the outer side wall of the T-shaped rotating groove 402. The driving motor 13 is fixedly connected to the side of the robot body 1 close to the connecting hole 403. The output shaft of the driving motor 13 is fixedly connected to the driving gear 12. The driving gear 12 passes through the connecting hole 403 and meshes with the tooth grooves 101. When using the arc-shaped scraping strip 7 to scrape and clean the outer side of the transparent cover 3, by starting the driving motor 13, the driving gear 12 is driven to rotate. The driving gear 12 passes through the connecting hole 403 and meshes with the tooth grooves 101 on the side surface of the T-shaped turntable 11 in the T-shaped rotating groove 402, thereby driving the T-shaped turntable 11 to slide and rotate in the T-shaped rotating groove 402. The rotating T-shaped turntable 11 drives the connecting rod 8 at the bottom to rotate, and then drives the arc-shaped scraping strip 7 to rotate and scrape on the outer wall of the transparent cover 3, completing the cleaning work of the sundries attached to the outer side of the transparent cover 3.
