DETAILED DESCRIPTION OF THE INVENTION

[0016] In order to make the above features and advantages of the present invention more comprehensible, the present invention will be described in detail below with reference to the accompanying drawings, but the present invention is not limited thereto.

[0017] The patrol robot includes a chassis housing A1 and a crawler mechanism A2 provided on both sides of the chassis housing A1, the chassis housing A1 being a rigid housing, and the crawler mechanism A2 including a crawler A3, a drive wheel A4 for driving the crawler, and a guide wheel A5 for guiding the crawler, wherein at least one of the guide wheels is a tension wheel A6 capable of adjusting the tension of the crawler.

[0018] By installing crawler mechanisms on both sides of the chassis housing, the crawlers are driven by the drive wheels to travel, and the guide wheels guide the crawlers. Furthermore, the tension of the crawlers can be adjusted by adjusting the tension wheels. This allows the patrol robot to operate in complex ground environments without problems such as slippage or unstable operation. Furthermore, in ground environments with overhead layers, the upper and lower elevators have excellent ability to cross gaps, preventing the conventional chassis wheels from getting caught in the gaps in the elevator car.

[0019] A fixed block A7 is attached to the inner wall surface of the chassis housing A1, adjacent to the tension ring A6. A guide groove A8 is formed in the fixed block, and the length of the guide groove A8 coincides with the tension adjustment direction of the tension ring A6. A sliding sleeve A10 is fixedly mounted at the portion where the wheel axle A9 of the tension ring A6 is inserted into the chassis housing. The sliding sleeve A10 slidably engages with the guide groove to limit its position. The tension ring A6 and the wheel axle A9 are coaxially fitted together and rotatable relative to each other. The sliding sleeve A10 and the wheel axle A9 are fixedly connected or integrated. A screw hole A11 is formed in the sliding sleeve, and the axial lines of the screw hole A11 and the wheel axle A9 are perpendicular to each other.

[0020] The fixed block A7 and the front wall plate A26 of the chassis housing are provided with a hole A27 coaxial with the screw hole A11, and a bolt A12 that can only rotate but cannot move axially is drilled into the hole. The bolt A12 can only rotate but cannot move axially. Two position limiting grooves are provided on the bolt A12, and snap rings are engaged in the position limiting grooves. The snap rings abut against the inner and outer surfaces of the front wall plate A26, thereby allowing the bolt A12 to only rotate but not move axially.

[0021] The bolt A12 is threaded into the screw hole A11, and the bolt A12 and slide sleeve A10 form a screw-nut mechanism, with the head of the bolt extending outside the chassis housing. When in use, the operator rotates the head of the bolt, and the rotation of the bolt A12 moves the slide sleeve A10 along the axial direction of the bolt within the guide groove A8. The wheel axle A9 and tension wheel A6 then move along the length of the guide groove A8, allowing the tension wheel A6 to adjust the crawler tension.

[0022] To ensure the stable and reliable adjustment of the tension ring A6, the inner end of the axle A9 of the tension ring is provided with a male thread, and a nut A13 is threaded onto the male thread, the end face of which is pressed against the side of the fixed block. By tightening the nut, the axle A9 and the tension ring A6 can be stably fastened in the corresponding positions.

[0023] There are three guide wheels A5, which are the first guide wheel, the second guide wheel, and the third guide wheel, respectively. The first guide wheel is a tension wheel, and the second guide wheel and the third guide wheel are installed horizontally. 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 drive wheel, and the guide position of the crawler is limited by the guide of the second guide wheel or the third guide wheel.

[0024] In order to facilitate the installation and removal of the storage battery, a window A15 for inserting and removing the storage battery A14 is opened in the front wall panel A26 of the chassis housing A1, and a removable connection window plate A16 is attached to the window, and the removable connection window plate A16 is connected to the window by a screw or a snap fit. A storage battery mounting frame A17 is provided to fix the storage battery in the chassis housing, and the storage battery mounting frame A17 may be a rigid frame corresponding to the shape of the storage battery, and the preferred shape of the storage battery is a rectangular parallelepiped. The storage battery mounting frame A1 7 may be a rectangular parallelepiped housing, one side of which has an opening as a draw-out port for the mounting frame, and the draw-out port faces the window. When attaching or detaching the battery, the removable connection window plate A16 is removed, the power supply path for the battery is attached, and then the battery is inserted into the battery mounting frame A17 (the battery mounting frame A17 has a snap fit for fastening or a clearance hole for locking the battery, which allows the battery to be fastened to the battery mounting frame A17), and then the removable connection window plate A16 is attached.

[0025] Compared to conventional batteries that are attached to the bottom of the patrol robot (which requires multiple people to help prevent the equipment from tipping over when attaching or detaching the battery, making the equipment more susceptible to collisions and damage, and also affecting the efficiency of attachment and detachment), this invention greatly simplifies the operation of attaching and detaching the battery.

[0026] In order to reduce damage to the wiring of the collision prevention bar sensor A18, the collision prevention bar sensor A18 is provided below the front wall panel A26 of the chassis housing A1, and the collision prevention bar sensor A18 is attached to a bumper positioning frame A19, which includes a first mounting bar A20 (which may be a solid bar or a grooved bar) and a second grooved slat A21 fixed (welded) vertically to both sides of the first mounting bar, wherein the first mounting bar A20 may be a solid bar or a grooved bar, and the second grooved slat A21 is a grooved steel, and the longitudinal sides of the first mounting bar A20 are used to attach the longitudinal portion of the collision prevention bar sensor A18, and the second grooved slat A21 is used to attach the widthwise portion that wraps around the collision prevention bar sensor A18.

[0027] The inner edge of the collision prevention bar sensor A18 is fixed to one side of the first mounting bar, and a passage A22 for passing the conductors of the collision prevention bar sensor is formed between the bottom of the groove of the second grooved slat and the side of the first mounting bar. The outer end of the second grooved slat has a slanted plate A23 for closing the outer end of the passage, and the end of the slanted plate abuts the side of the collision prevention bar sensor. The passage A22 and the above structure prevent the conductors of the collision prevention bar sensor from being exposed and being damaged by rats.

[0028] A U-shaped inclined support plate A29 is fixed to the outer side of the second grooved slat by welding, and the first mounting bar has a through hole A24 through which a screw for locking the collision prevention bar sensor is inserted. The U-shaped inclined support plate has a clearance hole A25, and the U-shaped inclined support plate is screwed and fixed to the front wall plate A26 of the chassis housing by a screw that passes through the clearance hole.

[0029] A charging socket module B is attached to a detachable connection window plate A16 of the chassis casing A1. The charging socket module B includes a charging socket housing B2 (made of plastic or other non-conductive material) with a mounting recess B1 and a cover plate B3 attached to the rear of the charging socket housing. The front of the charging socket housing B2 is provided with two sets of through-grooves B4, each communicating with the mounting recess B1. The through-grooves B4 have two independent, non-communicating sets on the charging socket housing B2 for attaching a positive charging socket piece and a negative charging socket piece. The positive charging socket piece and the negative charging socket piece are U-shaped bar plates B5 with elastic groove openings, the U-shaped groove openings of the positive charging socket piece and the negative charging socket piece directly facing the through-grooves B4, and a charging plug can be inserted through the through-grooves B4 into the U-shaped grooves of the pole pieces.

[0030] In poultry farms, contaminants such as dust and wet particles easily adhere to the charging plug, causing poor contact during charging. To prevent this, the present invention uses the elastic U-shaped bar plate B5 to move the chassis housing A1 closer to the charging socket housing B2 when the charging plug is inserted. During the insertion process, the elastic U-shaped bar plate B5 can scrape off dirt coated on the surface of the charging plug, ensuring good contact during charging.

[0031] To rationalize the design, the U-shaped bar plate B5 includes side plates B6 and an arc-shaped plate B7 connecting the bottoms of the side plates. The side plates have protrusions B8 extending inward at positions close to the U-shaped groove opening. 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 bar plate. The provision of the protrusions B8 improves the scraping effect of dirt and foreign matter.

[0032] To rationalize the design, the protrusions are arc-shaped and convex inward, and the minimum spacing between the arc-shaped transitions on the side plates is smaller than the width of the charging plug, which is advantageous for scraping off foreign matter from the surface of the charging plug. The arc-shaped protrusions allow the charging plug to be inserted more smoothly into the U-shaped grooves of the pole pieces; sharp protrusions are more likely to generate arcs, which will affect the service life and safety of the equipment components.

[0033] To achieve the installation position of the U-shaped bar plate B5, the U-shaped bar plate B5 has first protrusions B9 at both longitudinal ends, each having a flush portion B10 and a bent portion B11, a circular arc-shaped sunken groove B12 at the side of the through groove, the flush portion B10 abutting into the circular arc-shaped sunken groove B12, and a first compression spring B13 with a first end fitted into the bent portion provided in the circular arc-shaped sunken groove, the first end of which is fitted into the bent portion, the cover plate being locked to the charging socket housing with a screw, the inner surface of the cover plate B3 abutting against the second end of the first compression spring B13, and the pressure of the first compression spring maintaining a stable installation between the U-shaped bar plate B5 and the charging socket housing.

[0034] In addition, second protrusions B14 are provided on both sides of the central part of the U-shaped bar plate, and rectangular sunken grooves B15 for supporting the second protrusions are provided on both sides of the central part of the through groove. The second protrusions B14 can be formed by pressing a partial sheet onto the U-shaped bar plate body, and the second protrusions B14 are restricted in position by the rectangular sunken grooves B15. The installation of the first protrusions B9 and the second protrusions B14 makes the installation of the U-shaped bar plate B5 more stable and reliable.

[0035] Two elongated holes B16 are opened in the cover plate B3, and nuts that screw onto studs B28 are provided in the U-shaped bar plate at positions directly opposite the elongated holes. Electrical wires are passed through the elongated holes and connected and fixed to the studs and nuts, and electrical connection between the electrical wires and the U-shaped bar plate B5 is achieved by tightening the studs and nuts.

[0036] To rationalize the design, the charging plug B17 is attached to an extendable pole B18, and the extendable pole B18 is slidably connected to a charging box B19. A trigger switch B20 is installed opposite the charging box or the extendable pole. The trigger switch contacts the extendable pole or the charging box, and when the extendable pole is pressed and moved, the trigger switch is activated, forming a trigger switch conduction circuit as a circuit on / off switch. The trigger switch B20 may also use a position sensor, and when the position of the charging box or the extendable pole moves relative to it, the position sensor trigger circuit is conductive.

[0037] The extendable pole B18 extends from the outside of the charging box B19 and is connected to a first surface of the telescopic plate B29. A first end of a guide slide sleeve B21 is fixedly connected to a second surface of the telescopic plate. A guide rod B22 is installed within the guide slide sleeve B21 and is fixed to the charging box. A second compression spring B23 is installed between the second end of the guide slide sleeve B21 and a top plate B24 fixed to the charging box. A first end of the guide rod is fixed to the inner wall of the charging box and a second end of the guide rod is fixed to the top plate B24. Both ends of the second compression spring B23Z act between the top plate B24 and the telescopic plate B29. The action of the second compression spring B23 can position the telescopic plate B29 and the extendable pole B18 relatively to their initial positions (positions that do not trigger circuit conduction). After the charging plug B17 and the extendable pole B18 are pressed, the trigger switch B20 will be opened.

[0038] An elastic housing B25 is provided at the portion of the extendable post B18 where the charging plug is attached. The elastic housing B25 has two through-hole grooves B26 for the charging plug B17 to pass through. A return spring B27 is provided between the elastic housing and the extendable post. The return spring causes the outer end surface of the elastic housing to be flush with the outer end surface of the charging plug. After being pressed by the charging socket housing, the elastic housing is also pressed, allowing the charging plug to be inserted into the U-shaped groove of the pole piece. The elastic housing B25 and the extendable post B18 are connected to slide relative to each other.

[0039] In order to enable the imaging assembly of the patrol robot to be raised and lowered, a bottom plate A27 and a lifting structure C for the imaging assembly of the patrol robot are provided on the upper surface of the chassis housing A1, the bottom surface of the bottom plate A27 is flat, and the upper surface of the chassis housing A1 is also flat, and the bottom plate A27 and the chassis housing A1 can be connected by locking them with screws, facilitating a detachable connection between the bottom plate A27 and the chassis housing A1, and two to four handles A28 are provided on the bottom plate A27, which allow the entire bottom plate to be lifted and easily removed from the chassis housing A1, facilitating inspection of the chassis housing A1 or inspection of the lifting structure C or control equipment above the chassis housing A1.

[0040] Specifically, the lifting structure C of the imaging assembly of the patrol robot includes an electric push rod C1 fixed vertically to the upper surface of the bottom plate and a plurality of telescopic slide rails C2, the telescopic free end of the electric push rod is connected to the free ends of the plurality of telescopic slide rails, and each slide rail is fixedly connected to a seat plate C3 and at least one set of imaging assemblies C4 fixed to the seat plate.

[0041] By operating the electric push rod C1, each section of the multiple telescopic slide rails C2 can be raised and lowered sequentially, and the seat plates C3 connected to the slide rails of each section and the imaging assemblies C4 on the seat plates can be raised and lowered in conjunction with each other, allowing the imaging assemblies C4 to perform video scanning or image capture of poultry in poultry houses on different floors (usually, to improve space utilization, multiple floors of the poultry house are set up in one vertical space, and the height of each floor is 35 to 70 cm).

[0042] The specific plurality of telescopic sliding rails C2 includes two first guide rails C5 and a plurality of second guide rails C6 connected to each other so as to be slidable relative to one another in sequence. The two first guide rails C5 are fixed vertically to the bottom plate A27. The first second guide rail adjacent to the first guide rail is slidably connected to the first guide rail, and each adjacent second guide rail is slidably connected to the first guide rail in sequence. After the second guide rail that can slide to the highest position is connected to the free end of the electric push rod, when the electric push rod is operated, it drives the second guide rail that can slide to the highest position, causing each second guide rail to slide up and down in sequence.

[0043] Position limiting blocks C17 are provided between adjacent guide rails to limit the maximum and minimum stroke positions of the guide rails. Adjacent guide rails are able to slide relative to each other, and the installation of the position limiting blocks C17 prevents the guide rails from exceeding the maximum or minimum stroke.

[0044] Specifically, a guide groove C7 is provided on a first side of the guide rail, and a guide wheel C8 is rotatably connected to the guide groove of the adjacent guide rail on the second side of the guide rail, and slidably engages with the guide groove of the adjacent guide rail. There are at least two guide wheels C8 on each guide rail, and one guide wheel abuts on one side of the C-shaped guide groove and the other guide wheel abuts on the other side of the C-shaped guide groove.

[0045] Here, the seat plate C3 is fixedly installed on each second guide rail C6, a removable connecting plate piece C9 is attached to the seat plate, a position limiting guide groove C10 is provided on the removable connecting plate piece, a screw is drilled into the position limiting guide groove and connected to the seat plate C3, a horizontal bending piece and a hinge C11 connected to the horizontal bending piece are provided on the removable connecting plate piece, and an imaging assembly C4 is connected to the hinge, and the provision of the removable connecting plate piece C9 facilitates the removable connection of the imaging assembly C4 and the adjustment of the height position of the imaging assembly C4.

[0046] Preferably, a table C12 is horizontally and fixedly connected to the free end of the electric push rod C1, a seat plate is connected to the table top, and a set of imaging assemblies is attached to the seat plate. In the present invention, a slide rail (one of the second guide rails) that can slide to the highest position is fixedly connected to the table top, so that when the electric push rod moves up and down, the slide rail that can slide to the highest position moves up and down in conjunction with the slide rail, and thereby the other slide rails (other second guide rails) are sequentially moved up and down in conjunction with the slide rail.

[0047] In order to prevent the intrusion of foreign objects from outside the aircraft, each seat plate C3 is fixedly connected to a support frame C13 and a columnar, adjustable housing C14 fixed to the support frame. In this invention, there are three adjustable housings C14, which are nested one inside the other when they are at their lowest position. Of these, the lowest adjustable housing C14 is fixed and does not move, while the other two move up and down in accordance with the movement of the fixed base plate.

[0048] The above-mentioned liftable housing has an open passage C15 to avoid motion interference with the imaging assembly, and a folding curtain C16 is attached between the seat plates located on the adjacent slide rails above and below. The folding curtain faces the open passage and blocks foreign objects from entering the liftable housing. The liftable housing C14 and the folding curtain C16 prevent foreign objects from entering the interior, and can reduce the problem of the slide rails becoming contaminated and not being able to move up and down smoothly.

[0049] The above is merely a preferred embodiment of the present invention, and any equivalent changes and modifications within the scope of the claims of the present invention are within the scope of the present invention.
