As shown in FIGS. 1 to 4, the spin housing 10 according to an embodiment of the present invention is a housing that covers the camera C to protect the camera C such as CCTV or thermal imaging from the external environment. It is about.

For example, the spin housing 10 forms an arrangement space S in which the camera C is disposed, and includes a frame 100 forming an opening on the front side, a cover part 200 covering the opening, and the arrangement It may include a motor unit 300 disposed in the space S and applying rotational force to the cover unit 200 so that the cover unit 200 rotates with respect to the frame 100 .

For example, the frame 100 may have a box shape as a whole and may form the placement space (S).

The camera C may be disposed on the placement space S and protected from the external environment by the frame 100 .

For example, the frame 100 may form the opening on the front surface so that the camera C can photograph the outside.

For example, the opening may have a circular shape.

Meanwhile, as shown in FIGS. 1 and 2 , the cover part 200 covers the opening to prevent rainwater, foreign substances, etc. from flowing into the arrangement space S from the outside through the opening. can

Meanwhile, the motor unit 300 is disposed in the placement space S and is connected to the cover unit 200 to apply rotational force to the cover unit 200 so that the cover unit 200 rotates. can

For example, the motor unit 300 may be fixed to a support member K extending from the frame 100 and fixed at a predetermined position on the placement space S.

Hereinafter, referring to FIG. 2 , the rotation mechanism of the cover part 200 will be described in more detail. The cover part 200 receives rotational force from the rotation shaft X of the motor part 300 and rotates the glass. 210 and an enclosing portion 220 surrounding an edge of the glass 210 may be provided.

As the enclosing portion 220 is fixed to the glass 210 , it may be rotated in conjunction with the rotation of the glass 210 .

A known bearing module (B) may be disposed between the enclosing portion 220 and the frame 100 so that the enclosing portion 220 rotates smoothly with respect to the frame 100 .

Meanwhile, the rotational force of the rotation shaft X may not be directly transmitted to the glass 210 .

To this end, the glass 210 may form a through hole H having a larger diameter than the rotation shaft X to prevent direct contact with the rotation shaft X, and the cover part 200 may form a through hole H having a larger diameter than the rotation shaft X. 210) is connected to the rotating shaft (X) from the inside, and the inner pressing part 230 presses the inside of the glass 210, and is connected to the rotating shaft (X) from the outside of the glass 210, but the glass 210 ) May further include an outside pressing unit 240 for pressing the outside.

For example, a screw thread may be formed on the outer surface of the rotating shaft (X), and the inner pressing part 230 and the outer pressing part 240 may each form a screw hole screwed to the rotating shaft (X). .

As a result, the rotating shaft X and the inner pressing part 230 may be mutually screwed together, and the rotating shaft X and the outer pressing part 240 may be mutually screwed together.

The manager rotates the inner pressing part 230 and the outer pressing part 240 on the rotation axis X so that the inner pressing part 230 and the outer pressing part 240 press the glass 210. can do.

In addition, the cover part 200 may further include a head part 250 screwed to the rotating shaft X to prevent the outer pressing part 240 from being separated.

Meanwhile, between the inner pressing part 230 and the glass 210 and between the outer pressing part 240 and the glass 210, elastic parts made of an elastic material such as a rubber plate may be inserted and disposed.

Therefore, when the rotating shaft X of the motor unit 300 is rotated, the inner pressing part 230 and the outer pressing part 240 receive the rotational force of the rotating shaft X, so that the glass 210 can be forwarded to

As a result, the cover part 200 can be rotated based on the frame 100 .

On the other hand, the rotation mechanism of the cover part 200 is not limited to the above-described embodiment, and if the cover part 200 is a rotational mechanism based on the frame 100, it can be changed in various ways from the point of view of those skilled in the art. can

Hereinafter, rotation control of the cover unit 200 will be described in more detail.

For example, the spin housing 10 is disposed in the frame 100 and has a humidity sensor 400 that senses humidity to obtain humidity information and is disposed in the frame 100 and senses rainwater to obtain rainwater information. It may further include a rainwater detection sensor 500 to obtain.

For example, the humidity sensor 400 is arranged on the frame 100 to measure humidity and calculate the humidity information, and is placed on the bottom of the frame 100 so as not to be exposed to a rain or snow environment as much as possible. connection can be placed.

For example, the humidity information may be numerical information having a “%” unit, which is the size of humidity.

For example, the rainwater detection sensor 500 is arranged on the frame 100 and measures the amount of rainwater to calculate the rainwater information. It may be disposed connected to the upper surface of the frame 100 so as to be exposed to the maximum.

As an example, the rainwater information may be numerical information having a unit of "mm" which is a rainfall amount.

Meanwhile, the spin housing 10 may further include a control unit 600 that controls rotation of the motor unit 300 under a predetermined control condition based on the humidity information and the rainwater information.

For example, the controller 600 may be disposed on the placement space S, based on the humidity information calculated by the humidity sensor 400 and the rainwater information calculated by the rainwater sensor 500. It may be configured to control the degree of rotation (degree of rotation of the rotation shaft) of the motor unit 300.

Controlling the degree of rotation of the motor unit 300 by the control unit 600 may be controlled according to the predetermined control condition.

Hereinafter, referring to FIG. 4 , the predetermined control condition will be described in more detail.

For example, the predetermined control condition is to control the rotation of the motor unit 300 at a first rotation speed when the humidity information is less than the humidity threshold d1, and to control the rotation of the motor unit 300 when the humidity information is greater than or equal to the humidity threshold d1. This may be a condition for controlling the rotation of the motor unit 300 at a second rotational speed greater than the first rotational speed.

To explain this in more detail, as shown in FIG. 4 , the humidity information from 0 to the point just before t1 is less than the humidity threshold d1.

At this time, the humidity is relatively low so that the control unit 600 controls the rotation of the motor unit 300 at the first rotational speed (eg, 30 rpm) so that the cover unit 200 moves at the first rotational speed. can be rotated with

Even when the humidity information is 0%, the control unit 600 can control the motor unit 300 to rotate at the first rotational speed.

Even when the humidity is low, dust or dust may be adsorbed to the glass 210 or insects such as spiders may sit on the glass 210, so the control unit 600 determines that the humidity information is Even if it is less than the threshold value d1, the rotational operation of the motor unit 300 can be controlled at the first rotational speed.

Meanwhile, from the time point t1, the humidity information is equal to or greater than the humidity threshold d1.

At this time, as the humidity is relatively high, the control unit 600 controls the rotation of the motor unit 300 at the second rotational speed (eg, 60 rpm) greater than the first rotational speed from the time t1 to The cover part 200 may be rotated at the second rotational speed.

As a result, moisture deposited on the glass 210 due to high humidity may be evaporated due to rotation of the cover part 200 .

Meanwhile, the humidity threshold d1 may be predetermined by a manager, such as 40% or 50%.

Here, as an example, the predetermined control condition may be a condition for controlling rotation of the motor unit 300 based on the humidity information when the rainwater information is less than the rainwater threshold d2.

To explain this in more detail, as shown in FIG. 4 , the rainwater information from 0 to just before t2 is less than the rainwater threshold d2.

Accordingly, the controller 600 may ignore the rainwater information less than the rainwater threshold d2 from 0 to just before t2 and control the rotation of the motor unit 300 based only on the above-described humidity information.

That is, the control unit 600 controls the motor unit 300 to rotate at the first rotational speed according to the humidity information being less than the humidity threshold d1 from 0 to just before t1, and from t1 to t2 Until immediately before, the motor unit 300 may be controlled to rotate at the second rotational speed according to the humidity information being greater than or equal to the humidity threshold d1.

The rainwater threshold d2 may be determined in advance by a manager.

Here, as an example, the predetermined control condition may be a condition for controlling the rotation of the motor unit 300 at a third rotational speed greater than the second rotational speed when the rainwater information is equal to or greater than the rainwater threshold d2. .

To explain this in more detail, as shown in FIG. 4 , from t2 to just before t3, the rainwater information is equal to or greater than the rainwater threshold d2.

At this time, the control unit 600 ignores the humidity information and controls the rotation of the motor unit 300 at the third rotational speed (eg, 100 rpm) greater than the second rotational speed, thereby controlling the cover part. (200) can be rotated at the third rotational speed.

As a result, rainwater may not settle on the glass 210 due to the centrifugal force caused by the rotation of the cover part 200 .

Here, as an example, the predetermined control condition is that the rainwater information is equal to or greater than the rainwater threshold d2 so that the rotation of the motor unit 300 is controlled at the third rotational speed, while the rainwater information is the rainwater threshold d2. ), it may be a condition for controlling the rotation of the motor unit 300 at the third rotational speed for a preset time.

To explain this in more detail, as shown in FIG. 4 , the rainwater information is less than the rainwater threshold d2 from the time point t3.

That is, when the rainwater information was greater than or equal to the rainwater threshold d2 before time t3 based on time t3 and the rainwater information is changed to less than the rainwater threshold d2 from time t3, the control unit 600 controls the Immediately after t3, when the rainwater information is changed to less than the rainwater threshold d2, the rotation of the motor unit 300 is not controlled at the second rotational speed lower than the third rotational speed immediately, but from the time t3, the preset During the period, the rotation of the motor unit 300 may be controlled at the third rotational speed even though the rainwater information is less than the rainwater threshold d2.

As a result, fine moisture adsorbed to the glass 210 by rainwater may be evaporated due to rotation of the cover part 200 .

Here, as an example, the controller 600 may determine the preset time based on the amount of change in the humidity information.

To explain this in more detail, as shown in FIG. 4, from the time t3 to the time t4, the amount of change in the humidity information is relatively small, and from the time point t4, the amount of change in the humidity information (absolute value of the decreasing amount of change) is relatively big.

Here, it is assumed that the change in the humidity information from the time t3 to the time t4 is less than a predetermined threshold change (eg, “0.5”), and the change in the humidity information from the time t4 is equal to or greater than the threshold change.

Also, it is assumed that the time from time t3 to time t4 is 3 minutes.

At this time, the control unit 600 may set the preset time to 10 minutes, which is a relatively long time, according to the change amount of the humidity information at any time between the time point t3 and the time point t4 is less than the threshold change amount. .

That is, the control unit 600 may control the rotation of the motor unit 300 at the third rotation speed for 10 minutes from the time t3.

However, from the time t4, the control unit 600 changes the preset time to 5 minutes, which is relatively shorter than the previously set preset time of 10 minutes, according to the change amount of the humidity information greater than or equal to the threshold change amount. there is.

Accordingly, in the embodiment of FIG. 4 , the control unit 600 may control the rotation of the motor unit 300 at the third rotation speed for 5 minutes from the time t3.

If it is assumed that the time from time t3 to time t4 is 3 minutes, the controller 600 may control the rotation of the motor part 300 at the third rotation speed for 10 minutes from time t3.

Meanwhile, the control unit 600 may control on/off of power of the humidity sensor 400 and the rainwater detection sensor 500 based on the humidity information and the rainwater information.

To explain this in more detail, when the humidity information is less than the humidity threshold d1 and the rainwater information is greater than or equal to the rainwater threshold d2, at least one of the humidity sensor 400 or the rainwater sensor is in a non-ideal state can be inferred.

Therefore, when the humidity information is less than the humidity threshold value d1 and the rainwater information is equal to or greater than the rainwater threshold value d2, the control unit 600 controls the rotation of the motor unit 300 at the third rotational speed, , the humidity sensor 400 may be first turned off and then turned on.

Even after the humidity sensor 400 is turned off and then turned on, when the humidity information is less than the humidity threshold value d1 and the rainwater information is equal to or greater than the rainwater threshold value d2, the control unit 600 controls the Rotation of the motor unit 300 is continuously controlled at a rotational speed of 3, but the power of the rainwater detection sensor 500 may be turned off and then turned on secondarily.

Even after the power of the rainwater sensor 500 is turned off and then turned on, when the humidity information is less than the humidity threshold value d1 and the rainwater information is equal to or greater than the rainwater threshold value d2, the control unit 600 determines the While continuously controlling the rotation of the motor unit 300 at the third rotational speed, an alarm regarding occurrence of a non-ideal situation may be transmitted to a manager's electronic device (eg, terminal) through the communication unit 800 .

As shown in FIG. 3, the spin housing 10 may further include a memory unit 700 for storing the predetermined control conditions and the like, and may transmit and receive predetermined data to a manager's electronic device. A communication unit 800 may be further included.

In the above, the configuration and characteristics of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and various changes or modifications can be made within the spirit and scope of the present invention. It is apparent to those skilled in the art, and therefore such changes or modifications are intended to fall within the scope of the appended claims.
