[0034] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0035] The inspection robot includes a chassis box A1 and a track mechanism A2 arranged on both sides of the chassis box A1. The chassis box A1 is a rigid box. The track mechanism A2 includes a track A3, a driving wheel A4 that drives the track to move, and a guide wheel A5 for guiding the track, at least one of which is a tensioning wheel A6 that can adjust the tightness of the track.

[0036] By arranging crawler mechanisms on both sides of the chassis box, the crawlers realize the moving motion under the drive of the driving wheel, and the guidance of the crawlers is realized by the guide wheel. In addition, the tightness of the crawlers is adjusted by adjusting the tensioning wheel, so that the inspection robot can work in complex ground environments without slipping or unstable operation. In the ground environment with an overhead floor, the cross-ditch ability of the upper and lower elevators is strong, avoiding the problem of the chassis wheels getting stuck in the gap of the elevator car in the past.

[0037] A fixed block A7 close to the tensioning wheel A6 is installed on the inner wall surface of the above-mentioned chassis box A1, and the fixed block is provided with a guide groove A8. The length direction of the guide groove A8 is consistent with the tensioning adjustment direction of the tensioning wheel A6. The part of the wheel axle A9 of the tensioning wheel A6 that penetrates into the chassis box body is fixed with a sliding sleeve A10 that can slide and cooperate with the guide groove to limit the position, wherein the tensioning wheel A6 and the wheel axle A9 are coaxially sleeved and can rotate relative to each other. The sliding sleeve A10 is fixedly connected to the wheel axle A9 or made into one piece, and a threaded hole A11 is opened in the sliding sleeve, and the threaded hole A11 is perpendicular to the axis of the wheel axle A9.

[0038] A hole A27 coaxial with the threaded hole A11 is provided on the fixed block A7 and the front wall panel A26 of the chassis box, and a bolt A12 which can only rotate but not move axially is passed through the hole. The bolt A12 can only rotate but not move axially. Two limiting grooves can be provided on the bolt A12, and a retaining ring is clamped in the limiting groove. The retaining ring is placed on the inner and outer side surfaces of the front wall panel A26, so that the bolt A12 can only rotate but not move axially.

[0039] The bolt A12 is threadedly connected to the threaded hole A11, and the bolt A12 and the sleeve A10 form a screw-nut mechanism. The head of the bolt extends out of the chassis box. When in use, the operator rotates the head of the bolt, and the rotation of the bolt A12 drives the sleeve A10 to move axially in the guide groove A8, thereby driving the wheel axle A9 and the tensioning wheel A6 to move along the length direction of the guide groove A8, thereby realizing the tension adjustment of the track by the tensioning wheel A6.

[0040] In order to ensure the stability and reliability of the tensioning wheel A6 after adjustment, the inner end of the axle A9 of the above-mentioned tensioning wheel is provided with an external thread, and the external thread is threadedly connected to a nut A13 whose end face is pressed against the side of the fixed block. By tightening the nut, the axle A9 and the tensioning wheel A6 can be stably fastened in the corresponding positions.

[0041] The above-mentioned guide wheels A5 have three, namely the first guide wheel, the second guide wheel and the third guide wheel, among which the first guide wheel is a tensioning wheel, the second guide wheel and the third guide wheel are arranged horizontally, and the vertical distance between the upper edge of the first guide wheel and the lower edge of the second guide wheel or the third guide wheel is equal to the diameter of the driving wheel, and the guidance limit of the crawler track is achieved through the guidance of the second guide wheel or the third guide wheel.

[0042] In order to facilitate the installation and removal of the battery, a window A15 for taking and placing the battery A14 is opened on the front wall panel A26 of the above-mentioned chassis box A1, and a detachable connecting window panel A16 is installed on the window. The detachable connecting window panel A16 can be connected to the window by screws or buckles. A battery mounting rack A17 for fixing the battery is provided in the chassis box body. The battery mounting rack A17 can be a rigid rack with a shape comparable to that of the battery. The battery is preferably in a rectangular shape. The battery mounting rack A17 can also be a rectangular shell with an opening on one side to serve as a pull-out for the mounting rack. The opening is opposite to the window. When removing and installing the battery, the detachable connecting window panel A16 is removed, the battery power supply circuit is installed, and the battery is inserted into the battery mounting bracket A17 (the battery mounting bracket A17 may have a fastening buckle or a screw hole for locking the battery to achieve fastening of the battery to the battery mounting bracket A17), and then the detachable connecting window panel A16 is installed. Compared with the existing battery being installed on the bottom surface of the inspection robot (multiple people are required to help lay down the equipment when removing and installing the battery, which is not only easy to be bumped and damaged, but also affects the removal and installation efficiency), the present application greatly facilitates the removal and installation of the battery.

[0043] In order to reduce damage to the circuit of the anti-collision strip sensor A18, an anti-collision strip sensor A18 is provided below the front wall panel A26 of the above-mentioned chassis box A1, and the anti-collision strip sensor is installed on the anti-collision positioning frame A19. The anti-collision positioning frame A19 includes a first mounting bar A20 (which can be a solid bar or a groove bar) and a second grooved plate A21 vertically fixed (welded and fixed) on both sides of the first mounting bar. The first mounting bar A20 can be a solid bar or a groove bar, and the second grooved plate A21 is a channel steel. The side portion of the first mounting bar A20 in the longitudinal direction is used to install the longitudinal direction portion of the anti-collision strip sensor A18, and the second grooved plate A21 is used to install the width direction portion that wraps the anti-collision strip sensor A18.

[0044] The inner side of the anti-collision strip sensor A18 is fixed to one side of the first mounting strip, and a channel A22 for the wires of the anti-collision strip sensor to pass through is formed between the bottom of the second groove-shaped strip and the side of the first mounting strip. The outer end of the second groove-shaped strip is provided with an inclined plate A23 for closing the outer end of the channel, and the end of the inclined plate abuts the side of the anti-collision strip sensor; through the channel A22 and the above structure, the wires of the anti-collision strip sensor can be kept from being exposed, thereby preventing the exposed wires from being damaged by being gnawed by mice.

[0045] A U-shaped diagonal support plate A29 is welded and fixedly installed on the outer side of the above-mentioned second groove-shaped strip. A through hole A24 is provided on the first mounting strip, and a screw for locking the anti-collision strip sensor is passed through the through hole. A screw hole A25 is provided on the U-shaped diagonal support plate, and the U-shaped diagonal support plate is threadedly connected and fixed to the front wall panel A26 of the chassis box by screws passing through the screw holes.

[0046] A charging socket module B is installed on the detachable connecting window panel A16 on the chassis box A1. The charging socket module B includes a charging socket shell B2 (made of plastic material or other non-conductive material) with a mounting groove B1 and a cover plate B3 covering the back of the charging socket shell. The front of the charging socket shell B2 is provided with two groups of through grooves B4 respectively connected to the mounting grooves B1. The through grooves B4 have two independent and non-connected groups and are arranged on the charging socket shell B2 for installing the positive electrode plate and the negative electrode plate of the charging socket. The positive electrode plate and the negative electrode plate of the charging socket are U-shaped strips B5 with elastic notches. The U-shaped notches of the positive electrode plate and the negative electrode plate of the charging socket are opposite to the through grooves. The charging plug can pass through the through grooves B4 and be inserted into the U-shaped grooves of the electrode plates.

[0047] Since pollutants such as dust and wet particles are easily contaminated on the charging plug in poultry breeding places, resulting in poor contact during charging, the present application uses the elastic U-shaped strip B5 to move the chassis box A1 to allow the charging socket shell B2 to approach and the charging plug to be inserted. During the insertion process, the elastic U-shaped strip B5 can scrape off the dirt covering the surface of the charging plug, thereby ensuring good contact during charging.

[0048] For the sake of reasonable design, the above-mentioned U-shaped strip B5 includes two side panels B6 and an arc-shaped panel B7 connecting the bottom of the two side panels. The two side panels have relatively inward-extending protrusions B8 near the U-shaped groove. The protrusions B8 can scrape off foreign matter on the surface of the charging plug when the charging plug is inserted into the U-shaped strip. Since the protrusions B8 are provided, the effect of scraping off dirt and foreign matter is better.

[0049] For the sake of reasonable design, the above-mentioned raised portion is an inward-convex arc transition, and the minimum spacing of the arc transition on the two side plates is smaller than the width of the charging plug, so as to facilitate the scraping of foreign matter on the surface of the charging plug. The raised portion is an arc transition, which makes the charging plug smoother when inserted into the U-shaped groove of the pole piece. If a sharp raised portion is used, electric arcs are likely to occur, affecting the service life and safety of equipment components.

[0050] In order to achieve the installation and positioning of the U-shaped strip B5, the above-mentioned U-shaped strip B5 is provided with a first protrusion B9 at both ends in the length direction, and the first protrusion B9 has a flush section B10 and a bent section B11. The side of the through groove is provided with an arc-shaped recessed groove B12, and the flush section B10 abuts against the arc-shaped recessed groove B12. The arc-shaped recessed groove is provided with a first compression spring B13 with the first end sleeved on the bent section. The cover plate is locked on the charging socket shell by screws, and the inner side surface of the cover plate B3 presses on the second end of the first compression spring B13. Through the pressure of the first compression spring, the U-shaped strip B5 and the charging socket shell can be kept relatively stable.

[0051] In addition, second protrusions B14 are provided on both sides of the middle part of the above-mentioned U-shaped strip, and rectangular recessed grooves B15 for supporting the second protrusions are provided on both sides of the middle part of the through groove. The second protrusion B14 can be formed by punching a local sheet on the U-shaped strip body. The second protrusion B14 is limited in the rectangular recessed groove B15. Through the arrangement of the first protrusion B9 and the second protrusion B14, the installation of the U-shaped strip B5 is made more stable and reliable.

[0052] There are two strip holes B16 on the cover plate B3. Studs B28 and threaded nuts are provided on the U-shaped strip opposite the strip holes. Wires are inserted into the strip holes to connect and fix them with the studs and nuts. The locking of the studs and nuts realizes the electrical connection between the wires and the U-shaped strip B5.

[0053] For the sake of reasonable design, the above-mentioned charging plug B17 is installed on the retractable column B18, and the retractable column B18 is slidably connected to the charging box B19. A trigger switch B20 is relatively provided on the charging box or the retractable column. The trigger switch contacts the retractable column or the charging box to trigger the trigger switch when the retractable column is pushed and moved, so that the trigger switch serving as a circuit on-off switch can turn on the circuit. The trigger switch B20 can also use a position sensor. When the position of the charging box or the retractable column moves relative to each other, the position sensor triggers the circuit to turn on.

[0054] The retractable column B18 extends from the outside of the charging box B19 and is connected to the first surface of the retractable plate B29. The second surface of the retractable plate is fixedly connected to the first end of the guide sleeve B21. The guide sleeve B21 is sleeved with a guide rod B22 fixed on the charging box. A second compression spring B23 is provided between the second end of the guide sleeve B21 and the top plate B24 fixed in the charging box. The first end of the guide rod is fixed on the inner wall surface of the charging box, and the second end of the guide rod is fixed on the top plate B24. Both ends of the second compression spring B23Z act between the top plate B24 and the retractable plate B29. Through the action of the second compression spring B23, the retractable plate B29 and the retractable column B18 can be relatively located in the initial position (the position where the circuit is not triggered). When the charging plug B17 and the retractable column B18 are squeezed and pushed, the switch B20 is triggered to turn on the circuit.

[0055] An elastic cover B25 is provided at the location on the retractable column B18 where the charging plug is installed. The elastic cover B25 is provided with two through-hole slots B26 for the charging plug B17 to pass through. A return spring B27 is provided between the elastic cover and the retractable column so that under the action of the return spring, the outer end surface of the elastic cover is flush with the outer end surface of the charging plug. After being pushed by the charging socket shell, the elastic cover is pushed backward so that the charging plug can be inserted into the U-shaped groove of the pole piece. The elastic cover B25 is connected to the retractable column B18 in a relative sliding manner.

[0056] In order to realize the lifting and lowering of the camera assembly of the inspection robot, the upper surface of the above-mentioned chassis box A1 is provided with a base plate A27 and a lifting structure C of the inspection robot camera assembly provided on the upper surface of the base plate. The bottom surface of the base plate A27 is flat, and the upper surface of the chassis box A1 is also flat, so that the base plate A27 and the chassis box A1 can be locked by screws, thereby facilitating the detachable connection between the base plate A27 and the chassis box A1. In addition, 2-4 handles A28 are provided on the base plate A27 to facilitate lifting the base plate as a whole and separating it from the chassis box A1, thereby facilitating the maintenance of the chassis box A1, or the maintenance of the lifting structure C or control equipment above the chassis box A1.

[0057] Specifically, the lifting structure C of the inspection robot's camera assembly includes an electric push rod C1 vertically fixed on the upper surface of the base plate and a multi-section telescopic slide rail C2. The telescopic free end of the electric push rod is connected to the free end of the multi-section telescopic slide rail. Each section of the slide rail is fixedly connected to a seat plate C3 and at least one group of camera assemblies C4 fixed on the seat plate.

[0058] Through the operation of the electric push rod C1, the sections of the multi-section retractable slide rail C2 can be raised and lowered in sequence, thereby driving the seat plate C3 connected to each section of the slide rail and the camera assembly C4 on the seat plate to rise and fall, allowing the camera assembly C4 to perform video scanning or image collection on the poultry in the different layers of the poultry breeding house (usually to improve space utilization, several layers of breeding houses are set up in a vertical space, with each layer being 35-70 cm high).

[0059] The specific multi-section retractable slide rail C2 includes two first guide rails C5 and multiple second guide rails C6 that are connected to each other in a relative sliding manner. The two first guide rails C5 are vertically fixed on the base plate A27. The first second guide rail adjacent to the first guide rail is connected to the first guide rail in a relative sliding manner. The adjacent second guide rails are connected in a relative sliding manner. When the second guide rail that can slide to the highest position is connected to the free end of the electric push rod, the electric push rod drives the second guide rail that can slide to the highest position and drives each second guide rail to rise and fall and slide in sequence when it is working; a limit block C17 is provided between adjacent guide rails to limit the highest and lowest travel positions of the guide rails. The adjacent guide rails can slide relative to each other. By setting the limit block C17, the guide rail can be prevented from sliding out of the highest or lowest travel.

[0060] Specifically, a guide groove C7 is provided on the first side of the guide rail, and a guide wheel C8 is rotatably connected on the second side of the guide rail and slides with the guide groove of the adjacent guide rail. There are at least two guide wheels C8 on each guide rail, one guide wheel abuts against one side of the C-shaped guide groove, and the other guide wheel abuts against the other side of the C-shaped guide groove.

[0061] The seat plate C3 is fixed on each second guide rail C6, and a detachable connecting plate C9 is installed on the seat plate. The detachable connecting plate is provided with a limiting guide groove C10, and a screw is passed through the limiting guide groove to connect with the seat plate C3. The detachable connecting plate is provided with a horizontal bending plate and a loose-leaf C11 connected to the horizontal bending plate, and the loose-leaf is connected to the camera assembly C4. By providing the detachable connecting plate C9, the detachable connection of the camera assembly C4 and the adjustment of the height position of the camera assembly C4 are facilitated.

[0062] Preferably, the free end of the above-mentioned electric push rod C1 is horizontally fixedly connected to a top plate C12, and a base plate is connected to the top plate, on which a group of camera components are installed. In this application, the slide rail (one of the second guide rails) that can slide to the highest position is fixedly connected to the top plate, so that when the electric push rod is raised or lowered, the slide rail that can slide to the highest position is driven to rise or fall, and the slide rail in turn drives the other slide rails (the other second guide rails) to rise or fall.

[0063] In order to prevent the entry of dirt from outside the machine body, individual seat plates C3 are fixedly connected with a support frame C13 and a cylindrical liftable cover C14 fixed on the support frame. The present application has three liftable covers C14, which are nested with each other at the lowest working position, wherein the lowest liftable cover C14 is fixed, and the other two are lifted and lowered as the base plate to which they are fixed is lifted and lowered; the above-mentioned liftable cover is provided with an open channel C15 to avoid movement interference with the camera assembly, and a folding curtain C16 is installed between the seat plates located on the upper and lower adjacent slide rails, and the folding curtain is opposite to the open channel to block dirt from entering the liftable cover. The liftable cover C14 and the folding curtain C16 can prevent dirt from entering the interior, reducing the problem of smooth lifting and lowering caused by contamination of the slide rail.

[0064] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
