Description

Technical Field

[0001] This utility model relates to the field of retinal recognition technology, specifically a camera device for bovine retinal recognition. Background Technology

[0002] Bovine retinal image recognition systems can identify individuals through each cow's unique retinal vascular pattern. This identification method has minimal adverse impact on animal welfare, and because the biometric markers are immutable and unaffected, it can prevent theft and fraud. Research results show that the accuracy rate of identifying cattle using retinal vascular patterns is as high as 92.25%, indicating that retinal recognition technology is very successful in the identification and verification of cattle. Typically, a camera is used to capture images of the retina, and the cattle are identified by comparing them with retinal image data in a database.

[0003] Existing retinal recognition camera devices have lenses directly exposed to the outside environment. Cows carry a lot of dirt, and during recognition, the cow's head shaking, tail wagging, or body twisting may throw some dirt onto the camera lens, affecting the subsequent retinal recognition work. The lens needs to be cleaned manually, which is inconvenient. Furthermore, if the dirt contains sharp stones, the wiping action may cause the stones to scratch the lens, resulting in unclear images and affecting the accuracy of retinal recognition. Utility Model Content

[0004] The purpose of this invention is to provide a camera device for bovine retinal recognition, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A camera device for bovine retinal recognition includes:

[0007] The camera device body has a fixed frame fixedly installed on its outer side, and the upper and lower surfaces of the fixed frame are symmetrically provided with through grooves;

[0008] A protective component is fixedly installed on the outside of a fixed frame. The protective component includes a transparent soft rubber sheet that moves through multiple through slots. A cover plate is fixedly installed on the upper end of the fixed frame. A rotating rod is symmetrically rotatably connected inside the cover plate. Rubber wheels are symmetrically fixedly installed on the outer surface of the rotating rod.

[0009] The drying component is fixedly installed on the outside of the fixed frame;

[0010] The rinsing assembly is fixedly installed at the lower end of the fixed frame.

[0011] Furthermore, multiple support rods are symmetrically fixedly installed at the upper and lower ends of the fixed frame, and a rotating roller is rotatably connected between two symmetrical support rods located inside the transparent soft film, and both the rubber wheel and the rotating roller are in movable contact with the transparent soft film.

[0012] Furthermore, the outer surface of the transparent soft film has grooves molded at both ends, one end of the two rotating rods is fixedly connected to a No. 1 synchronous belt assembly, and a No. 1 motor capable of driving the rotating rods to rotate is fixedly installed on the outer side of the No. 1 cover plate.

[0013] Furthermore, the drying assembly includes:

[0014] The air intake shroud is fixedly installed on one side of the fixed frame.

[0015] The intake fan is fixedly connected to one end inside the intake shroud;

[0016] The second cover plate is fixedly installed on the lower surface of the fixed frame;

[0017] Two mounting brackets are fixedly installed on the lower surface of the mounting frame;

[0018] Two sponge rollers are rotatably connected to two fixed frames.

[0019] Preferably, a filter screen is fixedly installed at one end of the air intake hood, a second synchronous belt assembly is fixedly connected to one end of the two sponge rollers, a second motor capable of driving the sponge rollers to rotate is fixedly installed on one side surface of the second cover plate, and a drainage groove is opened on one side surface of the second cover plate.

[0020] Furthermore, the rinsing assembly includes:

[0021] Two water distribution pipes are fixedly installed on the lower surface of the fixed frame using brackets;

[0022] Multiple nozzles are fixedly connected at equal intervals to the outer surface of the water distribution pipe;

[0023] The water tank is fixedly installed on the other side of the fixed frame.

[0024] Preferably, a water pump is fixedly connected to the lower end of the water tank, and a T-junction is fixedly connected between the water pump and the two water distribution pipes.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. The operation of motor number one drives multiple rubber wheels to rotate, which in turn pushes the transparent soft film to rotate. This transparent soft film blocks the lens, preventing dirt from being directly thrown onto the lens. At the same time, the rotation of the transparent soft film moves the dirt downwards, and the water flow washes away the dirt. The sponge roller wipes and dries the transparent soft film, allowing it to be reused.

[0027] 2. The water pump operates, spraying clean water from inside the water tank through multiple nozzles on the surface of the transparent soft film via two water distribution pipes. This washes away the dirt with water flow, preventing it from splashing onto the lens and affecting subsequent retinal recognition. It also prevents wiping from scratching the lens with pebbles, maintaining the clarity of the lens and improving the accuracy of retinal recognition.

[0028] 3. When motor number two operates, the two sponge rollers rotate synchronously to wipe the water stains on the surface of the transparent soft film. At the same time, the air intake fan operates, and the outside air is filtered by the filter screen and introduced into the air intake hood and the No. 2 cover plate. Finally, it is discharged from the drain trough. During the air flow, the water stains on the surface of the transparent soft film are further dried, which speeds up the drying of the water stains. At the same time, the sponge rollers are dried, so that the sponge rollers can also be reused. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-5 In this embodiment of the present invention, a camera device for bovine retinal recognition includes a camera device body 1, a fixed frame 101 fixedly installed on the outside of the camera device body 1, through grooves 102 symmetrically opened on the upper and lower surfaces of the fixed frame 101, a protective component 2 fixedly installed on the outside of the fixed frame 101, the protective component 2 including a transparent soft rubber sheet 201 that movably passes through multiple through grooves 102, a first cover plate 203 fixedly installed on the upper end of the fixed frame 101, a rotating rod 204 symmetrically rotatably connected inside the first cover plate 203, rubber wheels 205 symmetrically fixedly installed on the outer surface of the rotating rod 204, a drying component 3 fixedly installed on the outside of the fixed frame 101, and a rinsing component 4 fixedly installed on the lower end of the fixed frame 101.

[0037] Specifically, the fixing frame 101 is installed on the outside of the camera device body 1 for installing other components. The protective component 2 blocks the lens without obstructing the shooting of the camera device body 1. The washing component 4 washes the transparent soft film 201 to remove dirt from its surface. The drying component 3 dries the residual moisture on the surface of the transparent soft film 201.

[0038] Example 1

[0039] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, multiple support rods 103 are symmetrically fixedly installed at the upper and lower ends of the fixed frame 101. A rotating roller 104 is rotatably connected between two symmetrical support rods 103 located inside the transparent soft film 201. Both the rubber wheel 205 and the rotating roller 104 are movably attached to the transparent soft film 201. Grooves 202 are molded at both ends of the outer surface of the transparent soft film 201. One end of the two rotating rods 204 is fixedly connected to a first synchronous belt assembly 206. A first motor 207 capable of driving the rotating rods 204 to rotate is fixedly installed on the outer side of the first cover plate 203.

[0040] In this embodiment, the No. 1 motor 207 operates, and through the transmission of the No. 1 synchronous belt assembly 206, the two rotating rods 204 rotate synchronously, driving multiple rubber wheels 205 to rotate. The groove 202 increases the friction between the rubber wheels 205 and the transparent soft film 201. The rotation between the rotating roller 104, the transparent soft film 201, and the support rod 103 reduces the friction of the transparent soft film 201, enabling the rubber wheels 205 to push the transparent soft film 201 to rotate. Thus, the transparent soft film 201 blocks the lens, preventing dirt from being directly thrown onto the lens. At the same time, rotating the transparent soft film 201 moves the dirt downward, allowing water to wash away the dirt. The sponge roller 306 wipes and dries the transparent soft film 201, enabling the transparent soft film 201 to be reused.

[0041] like Figure 1-3 As shown, in this embodiment, the rinsing assembly 4 includes: two water distribution pipes 401 fixedly installed on the lower surface of the fixed frame 101 by a bracket; multiple nozzles 402 fixedly connected at equal intervals to the outer surface of the water distribution pipes 401; and a water tank 405 fixedly installed on the other side surface of the fixed frame 101. A water pump 404 is fixedly connected to the lower end of the water tank 405, and a three-way pipe 403 is fixedly connected between the water pump 404 and the two water distribution pipes 401.

[0042] In practice, clean water is injected into the water tank 405, and the water pump 404 is activated. The clean water inside the water tank 405 is sprayed through multiple nozzles 402 of the two water distribution pipes 401 onto the dirty areas on the surface of the transparent soft film 201. This washes away the dirt with water flow, preventing dirt from being thrown onto the lens and affecting subsequent retinal recognition. It also prevents wiping from causing stones to scratch the lens, maintaining the clarity of the lens image and improving the accuracy of retinal recognition.

[0043] Example 2

[0044] Based on Example 1, in order to compensate for the problem that water stains on the surface of the transparent soft rubber pad 201 are not easy to dry quickly.

[0045] like Figure 2-4 As shown, in this embodiment, the drying component 3 includes: an air inlet hood 301 fixedly installed on one side surface of the fixed frame 101; an air inlet fan 302 fixedly connected to one end inside the air inlet hood 301; a second cover plate 304 fixedly installed on the lower surface of the fixed frame 101; two fixing brackets 305 fixedly installed on the lower surface of the fixed frame 101; and two sponge rollers 306 rotatably connected to the inside of the two fixing brackets 305 respectively. A filter screen 303 is fixedly installed at one end of the air inlet hood 301; a second synchronous belt assembly 307 is fixedly connected to one end of the two sponge rollers 306; a second motor 309 capable of driving the sponge rollers 306 to rotate is fixedly installed on one side surface of the second cover plate 304; and a drainage groove 308 is provided on one side surface of the second cover plate 304.

[0046] In practice, the second motor 309 operates, and through the transmission of the second synchronous belt assembly 307, the two sponge rollers 306 rotate synchronously to wipe the water stains on the surface of the transparent soft film 201. At the same time, the air intake fan 302 operates, and the outside air is filtered by the filter screen 303 and introduced into the air intake hood 301 and the interior of the second cover plate 304. Finally, it is discharged from the drain trough 308. During the air flow, the water stains on the surface of the transparent soft film 201 are further dried, and the drying speed of the water stains is accelerated. At the same time, the sponge rollers 306 are dried, so that the sponge rollers 306 can also be recycled.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
