[0002] Currently, for industrial production environments with oil mist, dust, water vapor and other pollutants, conventional monitoring devices are easily contaminated and cannot be used normally. At the same time, in the prior art, some monitoring devices are equipped with windshield wipers, which realize self-cleaning by spraying cleaning liquid and then using the windshield wiper to wipe the lens clean. However, such monitoring devices still have the risk of liquid droplet falling. In electrolytic aluminum plants and other industrial areas that are highly sensitive to liquid residue, environments with oil mist (water droplets need to be avoided to pollute oil products), and food processing sites and other special scenes that have strict requirements on cleanliness, liquid droplet falling can easily cause safety hazards or product quality problems.

[0025] As Figures 1-2As shown, the present disclosure provides an industrial monitoring device, which comprises a housing 1, an observation window 7, a monitoring camera 10, a first film clamp plate 5, a second film clamp plate 6 and a push-pull cylinder 4. The housing 1 is in a closed structure, and a sidewall is provided with a mounting hole. The observation window 7 is a transparent plate embedded in the mounting hole. The monitoring camera 10 is fixed in the housing 1, and the lens is opposite to the observation window 7.

The push-pull cylinder 4 is fixed to the housing 1, and is provided with a piston rod extending in a direction perpendicular to the plane of the observation window 7, and the end of the piston rod is fixedly connected with the first film clamp plate 5, so as to drive the first film clamp plate 5 to move close to or away from the observation window 7.

[0026] According to some embodiments of the present disclosure, the housing 1 comprises but is not limited to a closed hexahedral space enclosed by six flat plates through welding or bolt connection, and the housing 1 as a whole presents a cuboid or square structure. The mounting hole penetrates through one flat plate of the housing 1, and comprises but is not limited to a circular through hole, and the circular area is larger than the lens area of the monitoring camera 10. The observation window 7 comprises but is not limited to a transparent circular plate. The observation window 7 is embedded in the mounting hole and fixedly connected with the housing 1. The first film clamp plate 5 and the second film clamp plate 6 form two symmetrical gaps, and the two gaps are located on the side surface of the upper and middle positions of the first film clamp plate 5 and the second film clamp plate 6. The cross section of the two gaps comprises but is not limited to a rectangle.

[0027] Further, the two gaps and the opening parts of the first film clamp plate 5 and the second film clamp plate 6 form a containing space of the transparent film. The cross section of the containing space comprises but is not limited to a rectangle, and the length direction of the rectangle is parallel to the length direction of the transparent film, and the width direction of the rectangle is parallel to the width direction of the transparent film, wherein the width of the rectangle is larger than the width of the transparent film, so as to allow the transparent film to pass through. In addition, the extension length of the gap along the normal direction of the plane of the first film clamp plate 5 or the second film clamp plate 6 is matched with the thickness of the transparent film.

[0028] Further, the first film clamp plate 5 is connected with the shell 1 through the push-pull air cylinder 4. The push-pull air cylinder 4 comprises a cylinder body, a piston arranged in the cylinder body and a piston rod. The cylinder body is fixed to the shell 1, one end of the piston rod is fixed to the piston and the other end of the piston rod penetrates the cylinder body and is fixed to the first film clamp plate 5. The piston is driven to reciprocate in the cylinder body through air pressure, and the piston rod is driven to extend and retract. Specifically, when the transparent film is located in the accommodating space, the push-pull air cylinder 4 is retracted along the direction perpendicular to the plane of the observation window 7 through the piston rod, the first film clamp plate 5 and the second film clamp plate 6 are pulled to be close to the observation window 7, and the transparent film is driven to adhere to the outer surface of the observation window 7; the push-pull air cylinder 4 is extended along the direction perpendicular to the plane of the observation window 7 through the piston rod, the first film clamp plate 5 and the second film clamp plate 6 are pushed to be away from the observation window 7, and the transparent film is driven to be away from the outer surface of the observation window 7.

[0029] According to some embodiments of the present disclosure, on the one hand, the monitoring camera 10 is located inside the shell 1 in a closed structure, the monitoring camera 10 is physically isolated from the external environment, the shell 1 blocks the external pollutants, and the monitoring camera 10 is sealed and protected. On the other hand, the gap between the first film clamp plate 5 and the second film clamp plate 6 is formed, the transparent film can pass through the gap to protect the observation window 7, the U-shaped design of the first film clamp plate 5 and the second film clamp plate 6 is combined, the field of view of the monitoring camera 10 is not blocked, and the piston rod of the push-pull air cylinder 4 drives the first film clamp plate 5 and the second film clamp plate 6. When the transparent film is covered on the outer surface of the observation window 7, the pollutants in the external environment are blocked by the transparent film, and the observation window 7 is protected. When the transparent film is away from the outer surface of the observation window 7, the un-contaminated transparent film is replaced, and the observation window 7 is not contacted, which effectively prevents the observation window 7 from being damaged or contaminated. Therefore, when the monitoring camera 10 works in the environment with oil mist, dust and other pollutants, the cleanliness of the monitoring field of view is guaranteed, and the transparent film is used to avoid the pollutants such as water droplets in the monitoring process, which is beneficial to the long-term stable monitoring of the monitoring camera 10 in the environment with high cleanliness requirements.

[0030] According to some embodiments of the present disclosure, the outer surface of the observation window 7 is coplanar with the outer surface of the side wall of the shell 1 where the observation window 7 is located, and the edge of the observation window 7 is sealed and connected with the mounting hole through a sealing element.

[0031] According to some embodiments of the present disclosure, the push-pull cylinder 4 is configured to drive the first film clamp plate 5 to move between a first position close to the observation window 7 and a second position away from the observation window 7. Wherein, when the first film clamp plate 5 is in the first position, the transparent film is attached to the surface of the observation window 7, and when the first film clamp plate 5 is in the second position, the transparent film forms a gap with the observation window 7.

[0032] According to some embodiments of the present disclosure, the outer surface of the observation window 7 and the outer surface of the side wall of the housing 1 where the observation window 7 is located are in the same flat surface without protrusions or depressions. The sealing arrangement includes but is not limited to embedding a circular elastic sealing ring between the edge of the observation window 7 and the mounting hole, and the radial thickness of the sealing ring is adapted to the gap between the inner wall of the mounting hole and the circumferential side surface of the observation window 7, and the gap is filled by the elastic deformation of the sealing ring to block the flow of air, dust and other external pollutants into the housing 1.

[0033] According to some embodiments of the present disclosure, by forming a flat surface together with the outer surface of the observation window 7 and the outer surface of the side wall of the housing 1 where the observation window 7 is located, it is beneficial to attach the transparent film tightly, and in combination with the sealing of the sealing member, it effectively prevents external pollutants from contacting the observation window 7 and entering the inside of the housing 1 from the mounting gap of the observation window 7, and ensures the clean view of the monitoring camera 10. In addition, through the driving of the push-pull cylinder 4, the manual operation in the process of attaching and detaching the transparent film from the surface of the observation window 7 is reduced, which not only brings convenience to the use of the transparent film, but also effectively reduces the risk of pollution.

[0034] According to some embodiments of the present disclosure, the U-shaped openings of the first film clamp plate 5 and the second film clamp plate 6 are oriented in the same direction, the first film clamp plate 5 and the second film clamp plate 6 are attached to each other at positions opposite to the U-shaped opening orientation, and the push-pull cylinder 4 is fixed to the side wall of the housing 1 corresponding to the position opposite to the U-shaped opening orientation.

[0035] According to some embodiments of the present disclosure, the U-shaped surfaces of the first film clamp plate 5 and the second film clamp plate 6 are both perpendicular to the plane of the housing 1 where the observation window 7 is located, and the opening parts of the U-shaped surfaces are aligned with the position of the observation window 7. Wherein, the area of the opening part is larger than the area of the observation window 7. In addition, the fixing method of the second film clamp plate 6 and the first film clamp plate 5 includes but is not limited to facing and attaching the side surface of the lower position of the first film clamp plate 5 and the side surface of the lower position of the second film clamp plate 6, and realizing fixed connection by combining with bolts. The push-pull cylinder 4 is close to the lower position of the first film clamp plate 5 and the second film clamp plate 6.

[0036] According to some embodiments of the present disclosure, the U-shaped opening of the first film clamp 5 and the second film clamp 6 is designed to be co-directional, and the lower side of the first film clamp 5 and the second film clamp 6 is fixedly attached, and in combination with the fixing of the push-pull cylinder 4 at the corresponding lower position, the push-pull cylinder 4 drives the first film clamp 5 and the second film clamp 6 to move together by pushing or pulling the first film clamp 5, and the transparent film is stably close to or away from the outer surface of the observation window 7.

[0037] According to some embodiments of the present disclosure, the industrial monitoring device further comprises a fixed plate in the form of a flat plate. The fixed plate is fixed to the side wall of the shell 1 facing the U-shaped opening, the plane of the fixed plate is parallel to the side wall of the shell 1 facing the U-shaped opening, and is perpendicular to the plane of the observation window 7.

[0038] According to some embodiments of the present disclosure, the industrial monitoring device further comprises a feed shaft 9 and a take-up shaft 2. The feed shaft 9 and the take-up shaft 2 are symmetrically arranged on both sides of the shell 1, and each comprises a first shaft body and a first flange arranged at the axial ends of the first shaft body, the first flange protrudes from the first shaft body along the radial direction of the first shaft body. The first shaft body is vertically installed on the fixed plate.

[0039] According to some embodiments of the present disclosure, the first shaft body of the feed shaft 9 is wound with unused transparent film. The take-up shaft 2 is used to wind the transparent film from the feed shaft 9 and attached to the observation window 7.

[0040] According to some embodiments of the present disclosure, the fixed plate includes but is not limited to a rectangular plate, and the fixed plate is close to the upper position of the first film clamp 5 and the second film clamp 6. The first shaft body is in the form of a cylinder, and the extension direction is perpendicular to the normal direction of the plane of the observation window 7 and the normal direction of the flat plate of the fixed plate. The first flange is in the form of a circular plate structure, and is fixed to the two end faces of the first shaft body, respectively.

[0041] Further, the axial length of the first shaft body of the feed shaft 9 and the take-up shaft 2 is greater than the width of the transparent film. One of the first flanges of the feed shaft 9 is opposite to and fixedly connected with the fixed plate, and the other first flange is fixedly connected to the side wall of the shell 1 (the flat plate of the shell 1 where the push-pull cylinder 4 is located) which is parallel to and away from the fixed plate. The fixed connection form includes but is not limited to welding or bolt connection.

[0042] Specifically, the transparent film is a transparent long strip-shaped flexible film, which is provided by a cylindrical transparent film roll coaxially sleeved on the first shaft body of the feed shaft 9. The axis of the transparent film roll coincides with the axis of the first shaft body of the feed shaft 9.

[0043] Further, the diameter of the first flange of the feed shaft 9 and the take-up shaft 2 is greater than the outer diameter of the transparent film roll located on the first shaft body of the feed shaft 9.

[0044] According to some embodiments of the present disclosure, on the one hand, the fixed plate provides a stable mounting base for the feeding shaft 9 and the collecting shaft 2, thereby improving the stability of the overall structure. On the other hand, since the axial length of the first shaft body is greater than the width of the transparent film, and the diameter of the first flange is greater than the outer diameter of the transparent film roll, the transparent film roll on the feeding shaft 9 is limited by the first flange of the feeding shaft 9 at both axial ends, thereby preventing the transparent film from falling off the feeding shaft 9.

[0045] According to some embodiments of the present disclosure, the industrial monitoring device further comprises a motor 3. The motor 3 is fixed to the side of the fixed plate away from the shell 1, the output shaft of the motor 3 penetrates the shaft hole on the fixed plate, and is in transmission connection with one end of the first shaft body of the collecting shaft 2. The motor 3 drives the first shaft body of the collecting shaft 2 to rotate to wind up the transparent film.

[0046] According to some embodiments of the present disclosure, one of the first flanges of the collecting shaft 2 faces the fixed plate, and the other first flange is parallel to the side wall of the shell 1 (the flat plate of the shell 1 where the push-pull air cylinder 4 is located) away from the fixed plate. The first shaft body and the first flange of the collecting shaft 2 can rotate around their own axes relative to the fixed plate and the side wall of the shell 1. The connection form of the collecting shaft 2 and the fixed plate and the side wall of the shell 1 includes but is not limited to embedding a bearing on the end face of the first flange away from the first shaft body.

[0047] According to some embodiments of the present disclosure, the motor 3 drives the collecting shaft 2 to rotate to wind up the transparent film attached to the observation window 7, thereby preventing the transparent film with pollutants from falling off and causing pollution to the monitoring environment or adversely affecting the production process. Since the axial length of the first shaft body of the collecting shaft 2 is greater than the width of the transparent film, and the diameter of the first flange is greater than the outer diameter of the transparent film roll, the transparent film collected on the collecting shaft 2 is limited by the first flange of the collecting shaft 2, thereby preventing the transparent film from falling off the collecting shaft 2.

[0048] According to some embodiments of the present disclosure, the industrial monitoring device further comprises at least two guide shafts 8. The at least two guide shafts 8 are symmetrically arranged on both sides of the observation window 7, and each comprises a second shaft body and a second flange arranged at both axial ends of the second shaft body, the second flange protruding radially from the second shaft body. The second shaft body is vertically mounted on the fixed plate.

[0049] According to some embodiments of the present disclosure, the first end of the transparent film is connected to the first shaft body of the feeding shaft 9, the second end of the transparent film is connected to the first shaft body of the collecting shaft 2, and the part of the transparent film between the first end and the second end is arranged in the gap formed between the first film clamp plate 5 and the second film clamp plate 6.

[0050] According to some embodiments of the present disclosure, the second shaft body is a cylinder, and the extension direction is perpendicular to the normal direction of the plane of the observation window 7 and the normal direction of the plane of the fixing plate. The second flange is a circular plate structure, and is fixed to the two end faces of the second shaft body respectively. The axial length of the second shaft body is greater than the width of the transparent film. Each guide shaft 8 is fixed and connected to the fixing plate with one second flange facing the fixing plate, and is fixed and connected to the side wall of the shell 1 (the plane of the shell 1 where the push-pull air cylinder 4 is located) with the other second flange away from the fixing plate. The fixed connection forms include, but are not limited to, welding or bolt connection.

[0051] Further, the diameter of the second flange is greater than the diameter of the second shaft body. At the same time, each guide shaft 8 is closer to the observation window 7 than the feeding shaft 9 or the collecting shaft 2.

[0052] Specifically, before the transparent film roll is used, the end of the transparent film located in the innermost layer of the transparent film roll is the first end of the transparent film, and the end of the transparent film located in the outermost layer of the transparent film roll is the second end of the transparent film.

[0053] According to some embodiments of the present disclosure, by arranging the guide shaft 8, the transparent film released from the feeding shaft 9 continues to extend into the gap between the first film clamp plate 5 and the second film clamp plate 6. Since the axial length of the second shaft body is greater than the width of the transparent film, and the diameter of the second flange is greater than the diameter of the second shaft body, the transparent film on the guide shaft 8 is limited by the second flange, so as to avoid the transparent film from falling off the guide shaft 8.

[0054] According to some embodiments of the present disclosure, before the first use of the transparent film roll, the first film clamp plate 5 is moved to the second position away from the observation window 7 by the push-pull cylinder 4. In the first use of the transparent film roll, including but not limited to rotating the first shaft body of the transparent film roll relative to the feed shaft 9 about the axis, the transparent film is released from the surface of the transparent film roll in the form of being parallel to the first shaft body of the feed shaft 9 in the width direction of the transparent film, and the released transparent film is kept in the form of being parallel to the second shaft body of the guide shaft 8 in the width direction of the transparent film, and extends to the guide shaft 8 on one side of the observation window 7 in the length direction of the transparent film, wraps around the guide shaft 8, and continues to extend in the length direction of the transparent film, passes through the gap between the first film clamp plate 5 and the second film clamp plate 6, and then continues to extend to the guide shaft 8 on the other side of the observation window 7 in the length direction of the transparent film, wraps around the guide shaft 8, and continues to extend to the first shaft body of the take-up shaft 2 in the length direction of the transparent film. Subsequently, including but not limited to fixing the second end of the transparent film to the first shaft body of the take-up shaft 2 using adhesive tape. Further, the motor 3 is started to drive the first shaft body of the take-up shaft 2 to rotate, and the transparent film is rotated relative to the first shaft body of the take-up shaft 2 about the axis by the second end of the transparent film, and is wound around the first shaft body of the take-up shaft 2 in the form of being parallel to the first shaft body of the take-up shaft 2 in the width direction of the transparent film, to form a cylindrical recovery roll coaxially sleeved on the first shaft body of the take-up shaft 2. The axis of the recovery roll coincides with the axis of the first shaft body of the take-up shaft 2, and under the pulling of the second end of the transparent film, the transparent film roll rotates relative to the first shaft body of the feed shaft 9 about the axis to release the transparent film. Through such an embodiment, the transparent film can face the observation window 7.

[0055] Further, a locking mechanism is arranged between the transparent film roll and the first shaft body of the feed shaft 9 to lock the rotation of the transparent film roll. The locking mechanism includes but is not limited to a spring-loaded pin locking mechanism, specifically, the surface of the first shaft body of the feed shaft 9 is uniformly distributed with pin holes in the circumference, and the inner ring of the transparent film roll is provided with a spring-loaded pin at the corresponding position, when the pin is inserted into the pin hole, the transparent film roll is locked, when an external force acts on the transparent film roll to overcome the spring force, the pin is separated from the pin hole, and the transparent film roll can rotate.

[0056] Further, when the transparent film roll is locked by the locking mechanism, the transparent film passing through the gap between the first film clamp plate 5 and the second film clamp plate 6 is gradually tightened. At this time, the motor 3 is turned off, and the first film clamp plate 5 is moved to the first position close to the observation window 7 by the push-pull cylinder 4, and the transparent film is attached to the outer surface of the observation window 7.

[0057] In such an embodiment, the guide shaft 8 helps the transparent film to turn around during the process of extending along the length direction of the transparent film, so that the transparent film faces the observation window 7 for the purpose of attaching or replacing the transparent film. When the transparent film roll is locked, the transparent film is pulled tight, so that the subsequent transparent film attached to the observation window 7 is wrinkle-free, which is beneficial to realize continuous and clear monitoring view.

[0058] Further, the replacement mode of the transparent film attached to the outer surface of the observation window 7 is as follows: the first film clamping plate 5 is moved to the second position away from the observation window 7 by the push-pull cylinder 4, so that the transparent film is separated from the outer surface of the observation window 7. Then, the transparent film roll is unlocked, and the motor 3 is started to drive the material collecting shaft 2 to rotate. When the unused transparent film faces the observation window 7 (the transparent film attached to the observation window 7 has entered the recycled roll), the transparent film roll is locked, the motor 3 is turned off, and the first film clamping plate 5 is moved to the first position close to the observation window 7 by the push-pull cylinder 4, so that the unused transparent film is attached to the outer surface of the observation window 7.

[0059] In such an embodiment, the transparent film is separated from the observation window 7 to avoid the pollution or damage of the unused transparent film caused by friction, and the transparent film is replaced by the rotation of the material collecting shaft 2, so that the structure is simplified, the operation is convenient, and the pollution risk is reduced.

[0060] The above describes the embodiments of the present disclosure. However, these embodiments are only for illustrative purposes, and are not intended to limit the scope of the present disclosure. Although each embodiment is described above respectively, this does not mean that the measures in each embodiment cannot be used advantageously in combination. The scope of the present disclosure is defined by the appended claims and their equivalents. Without departing from the scope of the present disclosure, those skilled in the art can make various substitutions and modifications, which should all fall within the scope of the present disclosure.
