Description

  The present invention relates to a surveillance camera housing, and more particularly, to a device having rain protection in the outdoors.

In general, a surveillance camera housing for housing a surveillance camera is provided with a vent hole for releasing internal heat. Many of them have a structure in which a power source or a communication line is electrically connected to an internal monitoring camera with a connector. On the other hand, when the surveillance camera housing is provided outdoors, it is necessary to prevent water droplets from entering through the ventilation holes due to rain or preventing the connector from being shown by water droplets.
For this reason, conventionally, it has been common to provide a louver in the ventilation hole or to form the connector portion on the lower surface.

By the way, there is a case where the surveillance camera housing wants to change the direction of the photographic lens upward or downward depending on the installation location. However, if the ventilation hole is provided with a louver or the connector part is on the lower surface, changing the direction of the photographic lens will prevent water droplets from being rained, so change the direction of the photographic lens. The problem of being unable to do so arises.
In view of such a problem, an object of the present invention is to provide a rain guard that can function even if the direction of the photographing lens is changed in a surveillance camera housing in which a structure for avoiding rain is provided on a side surface.

In order to solve the above problems, the present invention has the following configuration.
The invention described in claim 1 is a rectangular parallelepiped or cylindrical housing in which a photographing device is housed and a photographing lens of the photographing device is provided on one bottom surface. A rain shield that is rotatably fixed around a rotation axis in the normal direction of the cover, and covers the intersection of the side surface and the rotation shaft with respect to water droplets from above when the normal direction is horizontal. A surveillance camera housing having a rain guard having a plate-like member having a rotational position to be hidden.
According to a second aspect of the present invention, in the surveillance camera housing, the rain protection portion is formed such that a base end side is rotatably fixed to the side surface, and a part of an outer surface is formed by a tubular body constituting the plate-like member. Is.

With the configuration as described above, the present invention has the following effects.
According to the first aspect of the present invention, if the orientation of the housing is selected so that the rotation axis of the rain protection portion is substantially horizontal even when the bottom surface to which the photographing lens is fixed is directed in any direction up, down, and side, Since the rain protection part can be rotated so that the shape member prevents rain, if a structure that does not want to be exposed to water droplets such as a vent or a connector at the rotation center position hidden by the plate-like member against rain, Even when the surveillance camera housing is installed with the photographing lens facing in an arbitrary direction in the outdoors, it is possible to prevent the structure portion that is not desired to be exposed to water droplets from being exposed to rain by rotating the rain shield.
According to the second aspect of the present invention, a rain barrier is formed by a tubular body, and by providing a structure that does not want to be exposed to water droplets inside the tubular body, a barrier is also formed on the lower side. The structure that you don't want to expose can be protected from water drops more.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of a monitoring camera housing X according to the present embodiment. The surveillance camera housing X includes a housing 10, a dome cover 20, a first rain guard 30, and a second rain guard 40. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB in FIG. As shown in FIGS. 2 and 3, the photographing apparatus M is built in the housing 10, and the photographing lens L of the photographing apparatus M is installed so as to be positioned in the dome cover 20. The photographing lens L is fixed so as to be rotatable about two axes so that it can photograph all directions on the front side.
The casing 10 is a substantially rectangular parallelepiped box made of synthetic resin, and a dome cover 20 is fixed to the bottom surface. The dome cover 20 is a hemispherical body made of a brown smoke transparent synthetic resin.

  Two first rain guards 30 are provided so as to be paired with opposing side surfaces of the housing. The first rain guard 30 includes an eaves member 31 and a support member 32. The support member 32 is a flat cylindrical body that protrudes outward and is integrally formed on the side surface of the housing 10, and a groove 32a is formed along the circumference. The eaves member 31 has a main surface 31a made of a substantially rectangular plate that obliquely intersects with the central axis of the cylindrical body constituting the support member 32, and a right angle from three sides of the main surface 31a close to the casing 10. It is a flat box-like body having one bottom surface and one side surface formed by side peripheral surfaces 31b that are connected to each other and bent to the housing 10 side. The edge of the side peripheral surface 31b facing the housing 10 is formed so that the entire edge is in contact with the protruding side surface of the housing 10 to be fixed. On the back surface of the eaves member 31, three claws 31c that are engaged with the grooves 32a of the support member 32 in a state where the side peripheral surface 31b is in contact with the side surface of the housing 10 are fixed. With such a structure, the eaves member 31 is fixed rotatably around the central axis of the support member 32 while maintaining the state where the eaves member 31 is engaged with the circular groove 32a of the support member 32 by the claw 31c. And when the center axis | shaft of the supporting member 32 is set | placed horizontally, the eaves member 31 comprises the plate-shaped member which can cover the center of the supporting member 32 with respect to the rain from upper direction by a rotation position. A punching metal plate 11 for dust removal is fixed to the inner surface side of the housing 10 at the position where the support member 32 of the first rain guard 30 is provided.

  Three second rain guards 40 are provided side by side above one side surface of the casing 10 where the first rain guard 10 is not provided. The second rain shield 40 is formed by a bent synthetic resin circular tube 41. A flange 41a is provided on the proximal end side of the circular tube 41 with a predetermined length from the opening edge, and a round hole formed on the side surface of the housing 10 having a size through which the flange 41a does not pass is provided as a flange of the circular tube 41. A portion on the base end side from 41a passes through the housing 10. A donut-shaped collar 41 b is fixed to the proximal end portion of the circular tube 41 located in the housing 10 so as not to be pulled out. With such a structure, the circular tube 41 is fixed so as to be rotatable around a rotation axis orthogonal to the side surface of the case 10 to be fixed. Moreover, the part which comprises the curved surface located in the outer side of the circular pipe 41 comprises the plate-shaped member which can cover the rotation center in the housing | casing 10 side surface with respect to the rain from upper direction by a rotation position. A connector C for electrical connection to the imaging device M such as a power connector and a communication connector is fixed in the circular tube 41.

Next, a method of using the surveillance camera housing X having the above configuration will be described. The surveillance camera housing X accommodates the imaging device M and is fixed to an outdoor wall surface or pole. At this time, when the dome cover 20 in which the photographing lens L exists is installed in the downward direction as shown in FIG. 1, the first rain protection portion 30 and the second rain protection portion 40 are installed as shown in FIG. The first rain guard 30 can suppress the rain from entering the housing, and the double rain guard 40 can suppress the rain from entering the connector portion. On the other hand, as shown in FIG. 4, when the dome cover 20 with the photographing lens is installed upward, the first rain guard 30 and the second rain guard 40 are rotated 180 degrees from the state of FIG. 1 to the state of FIG. So that the opening faces downward. Of course, the first rain guard 30 on the far side (not shown) is also rotated 180 degrees. As a result, the first rain guard 30 can also prevent rain from entering the housing against rain from above, and the double rain guard 40 can suppress rain from entering the connector. Further, when the dome cover 20 where the photographing lens is present is turned sideways, as shown in FIG. 5, the second rain protection portion 40 is located below, and the first rain protection portion 40 located on the side is arranged as shown in FIG. Rotate 90 degrees from the state to the state of FIG. 5 so that the opening faces downward. Of course, the first rain guard 30 on the back side (not shown) is also rotated by 90 degrees. As a result, the first rain guard 30 can also prevent rain from entering the housing against rain from above, and the double rain guard 40 can suppress rain from entering the connector.
As described above, in the surveillance camera housing X according to the present embodiment, since the rain protection portion that covers the structure that is desired to avoid raining outdoors is fixed to be rotatable, the rain protection portion is adapted to the direction of the photographing lens portion. Rotate the to properly cover the part you want to avoid raining.

In addition, since the electric cable may be twisted and cut when the second rain protection portion 40 rotates indefinitely, it is desirable to provide a restriction structure that does not rotate more than a predetermined rotation angle. The predetermined rotation angle in this case is exemplified by 360 degrees, 270 degrees, and 90 degrees. However, if the inner periphery of the second rain protection portion 40 is separated from the electrical connector C, the second rain protection portion 40 rotates around the electrical connector C, so that it is not necessary to provide a structure for restricting the rotation.
Further, in the above embodiment, the housing 10 has a rectangular parallelepiped shape, but the housing 10A may be formed in a cylindrical shape like the monitoring camera housing Y shown in FIG. Although the housing 10A of the monitoring camera housing Y in FIG. 6 is a cylinder, it may be a cylindrical body that decreases in one direction, such as a rectangular cylinder such as a hexagonal cylinder or an octagonal cylinder, or a truncated cone.
In the above embodiment, the first rain protection portion is formed in a flat box shape having no bottom surface and one side surface, and the second rain protection portion is formed in a bent circular tube shape, but may have a structure having a plate shape to prevent rain. Various modifications are possible, and the shape can be changed as appropriate, such as a simple bowl-like shape or a dome shape in which a hemisphere is further halved. Moreover, various structures can be adopted as long as the rotation mechanism of the rain guard can also rotate appropriately. Further, a sealing member may be provided at an appropriate position in order to improve the water tightness of the rotating mechanism.
