Referring to fig. 1, in the embodiment of the present utility model, the window glass 20 is covered at the opening of the accommodating space (not shown in the drawings) so as to seal the lens 60 inside the accommodating space, it can be appreciated that in the embodiment of the present utility model, when the window glass 20 is specifically disposed, the window glass 20 may be disposed on the inner wall of the opening, that is, a certain space may be disposed/reserved between the outer surface of the window glass 20 and the edge of the opening, so as to facilitate the disposition of the protective cover 30.

In the embodiment of the present utility model, the connection mode between the window glass 20 and the housing 10 may be a clamping connection, or may be an adhesive bonding, or may be a threaded connection; in some examples, window glass 20 and housing 10 may also be connected by fasteners such as screws, bolts, screws, nuts, and the like; it will be appreciated that the window glass 20 may be transparent, although in some examples, the window glass 20 may be a glass with a color filter to avoid overexposure during photographing by the monitoring device.

In the embodiment of the utility model, the protective cover plate 30 is connected and arranged on the shell 10, and the protective cover plate 30 is arranged on one side of the window glass 20, which is away from the accommodating space; like this, when the protective cover 30 shelters from in window glass 20's outside, form a sealed environment between protective cover 30 and the casing 10 to form the resistance to the sand and wind granule, sand and dust or the rainwater of external environment, reduced the contact of sand and wind, particulate matter, sand and dust or rainwater and window glass 20, thereby reduced the particulate matter to window glass 20 surface beat wearing and tearing scraping, can effectively protect window glass 20, reduce window glass 20's wearing and tearing that receive under adverse environmental conditions, can effectively prolong window glass 20's life.

Referring to fig. 1, in the embodiment of the present utility model, the protective cover 30 is movably connected to the housing 10. Specifically, the protective cover 30 may be slidably coupled to the housing 10 in embodiments of the present utility model. For example, a chute may be disposed at the opening of the housing 10, the protective cover 30 is disposed in the chute, and the protective cover 30 is driven by the driving member 50 to move, so that the protective cover 30 shields the window glass 20; alternatively, the driving member 50 drives the protective cover 30 to move, so that the protective cover 30 is moved away from the side of the window glass 20 facing away from the accommodating space.

For example, in the embodiment of the present utility model, the protective cover plate 30 may be provided in an arc-shaped structure (for example, a hemispherical surface); the protective cover 30 may be covered on the outer side of the window glass 20; the driving member 50 may drive the protective cover 30 to rotate in a radial direction of the arc structure, i.e., rotate the protective cover 30 to the rear side of the window glass 20 (e.g., the side facing the accommodating space), or rotate the protective cover 30 to the rear side of the lens 60. It will be appreciated that when the window glass 20 needs to be protected, the driving member 50 may drive the protective cover plate 30 to rotate to a side of the window glass 20 opposite to the accommodating space, where the protective cover plate 30 and the housing 10 form a closed space, so that sand dust, sand wind, particles or rainwater in the external environment are blocked outside, and abrasion of the window glass 20 caused by the sand dust, sand wind, particles or rainwater can be effectively avoided.

It will be appreciated that in the embodiment of the present utility model, when the present utility model is specifically configured, the moving directions of the two protection cover plates 30 may be set to be opposite, for example, taking fig. 1 as an example, one protection cover plate 30 located on the left side in fig. 1 may be rotated in a counterclockwise direction, and one protection cover plate 30 located on the right side in fig. 1 may be rotated in a clockwise direction. In this way, the movement formation and the movement space of the two protective cover plates 30 can be reduced, i.e. the overall space of the monitoring device is reduced.

With continued reference to FIG. 1, in an embodiment of the present utility model, an environmental monitoring sensor 40 may be coupled to the housing 10. Specifically, the environmental monitoring sensor 40 may be connected to the outside of the housing 10, for example, by a connection member such as a bolt, a screw, or a screw, etc., to be connected to the housing 10. In some examples, the environmental monitoring sensor 40 may be connected to the housing 10 by a snap fit or an adhesive.

In alternative examples of embodiments of the utility model, at least a portion of the environmental monitoring sensor 40 may be disposed on a side of the protective cover 30 facing away from the window glass 20. The environmental monitoring sensor 40 may also be disposed within the housing 10 when specifically disposed. It should be noted that, when the environment monitoring sensor 40 is disposed in the housing 10, the sensor probe of the environment monitoring sensor 40 may extend out of the housing 10 so as to monitor the external environment.

In embodiments of the present utility model, the environmental monitoring sensor 40 may be any one of a dust sensor, a dust sensor (which may also be referred to as a PM2.5 sensor in some examples), a PM10 sensor, a rain and fog sensor, or a rainfall sensor. In other alternative examples of embodiments of the present utility model, the environmental monitoring sensor 40 may also be a dust sensor, a dust sensor (which may also be referred to as a PM2.5 sensor in some examples), a PM10 sensor, a rain and fog sensor, or a combination of multiple ones of the rain sensors.

When the environment monitoring sensor 40 is specifically used, in the embodiment of the present utility model, the PM2.5 concentration (for example, the PM2.5 sensor) in the environment may be specifically monitored, the PM10 concentration (for example, the PM10 sensor) may also be monitored, for example, the rain and fog amount (for example, the rain sensor) in the environment may be monitored, and the monitored environment data is transmitted to the comparing circuit in the processor for processing and comparing, where the processor may be a central processing unit (Central Processing Unit, CPU for short), a micro control unit (Microcontroller Unit, MCU for short), or a field programmable gate array (Field Programmable Gate Array, FPGA for short) or the like. In the embodiment of the utility model, the processor can also be a self-contained processor of the monitoring equipment.

Fig. 3 is a control flow chart of driving a protective cover plate by a driving member in the lens window protection device according to the embodiment of the utility model.

As a specific example of an embodiment of the present utility model, referring to fig. 3, an embodiment of the present utility model is illustrated with the environment monitoring sensor 40 being a PM2.5 sensor as a specific example.

In the embodiment of the utility model, the PM2.5 sensor monitors the environmental condition, specifically, the PM2.5 sensor can monitor the concentration of PM2.5 in the environment and send the monitored concentration data to the comparison circuit in the processor. The processor processes data sent by the PM2.5 sensor. It may specifically be compared to a preset concentration data threshold to determine whether protection of the window pane 20 is required. For example, when the concentration of PM2.5 is greater than or equal to the preset concentration threshold, it may be determined that protection of the window glass 20 is required. As a specific example, the preset concentration threshold may specifically be 150. Mu.g/m ³ -250μg/m ³ . In some specific examples, the preset concentration threshold may specifically be 150 μg/m ³ 、200μg/m ³ Or 250. Mu.g/m ³ Etc.

In some optional examples of the embodiments of the present utility model, the processor processes the data sent by the PM2.5 sensor, and the processing may be performed to obtain the pollution condition of the current environmental condition, for example, the weather pollution condition such as light pollution, moderate pollution, heavy pollution, serious pollution, and sand storm. Thus determining whether or not protection of the glazing 20 is required based on the corresponding weather conditions, for example, it may be generally set to protect the glazing 20 in heavy conditions and more severely polluted weather conditions.

Fig. 4 is a schematic diagram of another structure of a lens window protection device according to an embodiment of the utility model.

Specifically, in the embodiment of the present utility model, when the processor determines that the current environmental condition needs to protect the window glass 20, referring to fig. 3 and 4, the driving member 50 may drive the protective cover 30 to move towards each other, and may specifically move the protective cover 30 to the front end/front side of the window glass 20 (e.g. the side of the window glass 20 facing away from the accommodating space), so as to seal and shield the window glass 20, thereby avoiding abrasion and scratch of the window glass 20 caused by dust, floating dust or sand in the environment, and effectively protecting the window glass 20.

It will be appreciated that the protective cover 30 may be slidably coupled to the housing 10 as described in detail in the foregoing embodiments of the utility model. Therefore, in the embodiment of the present utility model, the driving member 50 may be specifically a linear driving member 50 such as an electric cylinder, an air cylinder, a piston cylinder, or a linear motor. For example, the protection cover 30 is connected to the housing 10 in a sliding manner, and when the glass 20 needs to be protected, the processor may generate a monitoring signal (for example, a first monitoring signal) that needs to be protected on the glass 20; at this time, the electric cylinder, the air cylinder, the piston cylinder or the linear motor may drive the protective cover 30 to move along a straight line according to the first monitoring signal, so as to seal and shade the window glass 20.

In other examples of embodiments of the present utility model, the protective cover 30 may be rotatably coupled to the housing 10. Thus, in embodiments of the present utility model, the driving member 50 may also be a motor, such as: a driving member 50 for driving the protective cover 30 to rotate, such as a synchronous motor, a stepping motor, or a servo motor. For example, as described in detail in the foregoing embodiments of the present utility model, the protective cover 30 is configured in an arc-shaped or hemispherical structure, and the processor may generate a monitoring signal (e.g., a first monitoring signal) that requires protection of the window glass 20 when the window glass 20 is required to be protected; at this time, the motor may drive the protective cover 30 to rotate to the front side of the window glass 20 through a gear, a driving pulley, a sprocket, or the like according to the first monitoring signal, thereby protecting the window glass 20.

The embodiment of the utility model provides a lens window protection device, which is characterized in that two movable protection cover plates 30 are arranged on the outer side of window glass 20, an environment monitoring sensor 40 is used for monitoring environment conditions, and when the environment conditions are characterized in that the window glass 20 needs to be protected, the environment monitoring sensor 40 sends out a first monitoring signal; the driving piece 50 that is connected with two protection apron 30 respectively drives two protection apron 30 according to first monitoring signal and removes in opposite directions to shelter from in window glass's outside, and protect window glass, compare with prior art through the removal in opposite directions of two protection apron, can reduce the space that needs to occupy when every protection apron removes, promoted space utilization.

Fig. 5 is a schematic diagram of another structure of a lens window protection device according to an embodiment of the utility model.

In some alternative examples of embodiments of the present utility model, referring to fig. 3 and 5, the driving member 50 is further adapted to drive the two protective cover plates 30 to move back to each other according to a second monitoring signal of the environmental monitoring sensor 40, such that the protective cover plates 30 are moved away from the outside of the window glass 20, the second monitoring signal being a monitoring signal of an environmental condition suitable for photographing by the lens 60.

It will be appreciated that when the environmental conditions sensed by the environmental monitoring sensor 40 are such that no protection of the glazing 20 is required, for example, the PM2.5 sensor senses a good air quality (less than or equal to 150 μg/m dust content in air) ³ ) The content of dust, sand and other particles in the air is low, so that the window glass 20 is not damaged, as shown in fig. 3 and 5, the monitoring data of the environmental monitoring sensor 40 can generate a second monitoring signal after being processed by the processor, the driving member 50 can drive the protective cover plate 30 to move away from the front side (e.g. the side facing away from the accommodating space) of the window glass 20 according to the second monitoring signal, for example, as shown in fig. 5, the driving member 50 can rotate the protective cover plate 30 to two sides of the window glass 20. Alternatively, in some examples, the driving member 50 may move the protective cover 30 to one side of the window glass 20 when the protective cover 30 is slidably coupled to the housing 10.

Thus, the driving member 50 can move the protective cover plate 30 away from the front side of the window glass 20 in time under the condition of good environmental conditions, so that the monitoring equipment can monitor and shoot the outside in time. It should be noted here that, in some examples, the protective cover 30 may also be a transparent cover, that is, the monitoring device may perform the monitoring photographing even if the protective cover 30 is not removed from the front side of the window glass 20.

In an alternative example of embodiment of the present utility model, referring to fig. 1 and 4, the driving member 50 drives the protective cover plates 30 to rotate, and the rotation planes of the two protective cover plates 30 coincide with the plane of the window glass 20.

In other words, the rotation plane of the protective cover 30 is parallel or approximately parallel to the plane of the window glass 20 when the protective cover 30 is driven by the driving member 50. In addition, referring to fig. 1, 4 and 5, in the embodiment of the present utility model, the rotation axis of the protection cover plate 30 may be located outside the area covered by the window glass 20.

Here, the rotation angle of the protective cover 30 may be adjusted according to the size of the protective cover 30 and the size of the window glass 20. As a specific example of the embodiment of the present utility model, the protective cover 30 may be partially rotated, and in this case, the driving member 50 may be a motor capable of rotating in both forward and reverse directions.

In alternative examples of embodiments of the present utility model, the driving member 50 may also be a stepping motor that drives the protective cover 30 to rotate in the same direction, in which case the driving member 50 may be a stepping motor that can control the rotation angle, for example, in the case that the protective cover 30 needs to be moved away from the front side of the window glass 20, in which case the driving member 50 may drive the protective cover 30 to rotate 90 ° -180 °, so that the protective cover 30 no longer shields the window glass 20. In the event that protection of the window pane 20 is desired, the drive 50 may continue to drive the protective cover 30 in the same direction such that the protective cover 30 is rotated through 360 ° and back to the front side of the window pane 20, thereby forming a barrier seal for the window pane 20.

According to the embodiment of the utility model, the protection cover plate 30 is driven to rotate by the driving piece 50, and the rotation plane of the protection cover plate 30 is consistent with the plane of the window glass 20, so that the protection cover plate 30 and the window glass 20 can be arranged along the whole length direction of the monitoring equipment, the occupation of the protection cover plate 30 on the whole space of the monitoring equipment can be reduced, the whole structure of the monitoring equipment is more compact, and the whole volume of the monitoring equipment is reduced.

Fig. 6 is an exploded view of a lens window protection device according to an embodiment of the present utility model.

In another alternative example of the embodiment of the present utility model, as shown in fig. 6, there may be two protective cover plates 30, and as shown in fig. 1 and fig. 4-6, two protective cover plates 30 are located on opposite sides of the window glass 20, and the moving directions of the two protective cover plates 30 are opposite.

It will be appreciated that in embodiments of the present utility model, when it is desired to protect the window pane 20, the two protective cover plates 30 may be moved in a direction toward/toward each other. For example, when the protective cover plates 30 are slidably coupled to the housing 10, the two protective cover plates 30 may be moved toward each other.

Alternatively, in other examples of embodiments of the utility model, both protective cover plates 30 may be rotatably coupled to housing 10; when both cover plates are rotatably connected to the housing 10, the rotation directions of both cover plates may be reversed. For example, in the case where it is desired to protect the window glass 20, as illustrated in fig. 1, one of the protective cover plates 30 located on the left side (the position direction in fig. 1 is taken as an example) may be rotated in the counterclockwise direction, and one of the protective cover plates 30 located on the right side may be rotated in the clockwise direction.

In the embodiment of the utility model, by arranging the two protection cover plates 30, and the two protection cover plates 30 have opposite movement directions, the area to be protected of the window glass 20 is shared by the two protection cover plates 30, so that the occupied area or space of each protection cover plate 30 can be reduced, the whole volume of the monitoring equipment can be effectively reduced, the whole structure of the monitoring equipment is more compact, the monitoring equipment can adapt to more use environments, and the universality of the monitoring equipment is improved.
