Description

Technical Field

[0001] The present invention relates to the technical field of computer room monitoring, and particularly relates to a monitoring device and a monitoring method for a computer room. Background Art

[0002] The computer room is very important for the storage of computer data. Therefore, monitoring devices are usually set up to monitor the computer room to ensure its safety. Currently, most of the installed monitoring devices are fixedly installed and cannot be moved and adjusted, so they cannot monitor the devices at different positions in the computer room.

[0003] Chinese invention patent CN119042471A discloses a monitoring device for a data center computer room and its usage method. By installing an electric telescopic rod in the middle of the bottom end of a fixed plate, the height of the monitoring camera can be adjusted. By installing a monitoring camera at the output end of an electric pan-tilt, the monitoring camera can be adjusted at multiple angles, which is convenient for users to monitor the computer room.

[0004] The above device enables the monitoring device to move horizontally through the cooperation of a slide rail and a slider. However, since there is no relevant structure on the slide rail for guiding the slider out, when the device needs to be repaired, the staff can only work at heights, which is rather inconvenient. In summary, the above device still has room for improvement.

[0005] Therefore, it is necessary to provide a monitoring device and a monitoring method for a computer room to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a monitoring device and a monitoring method for a computer room to solve the problem that in the existing device, the monitoring device can move horizontally through the cooperation of a slide rail and a slider, but since there is no relevant structure on the slide rail for guiding the slider out, when the device needs to be repaired, the staff can only work at heights as mentioned in the above background art.

[0007] Based on the above idea, the present invention provides the following technical solution: A monitoring device for a computer room, including a slide rail and an upper housing that slides below the slide rail. A lower housing for installing a camera unit is arranged below the upper housing. Two sets of rollers that cooperate with the slide rail are arranged at the upper housing. One end of the slide rail is provided with a pair of main support rods, and auxiliary support rods are arranged on both sides of the main support rods; Joints are hinged at the top ends of both the main support rod and the auxiliary support rod. One end face of each joint is provided with a jack, and inserting rods that are matched with the jacks are fixedly arranged on both sides of the upper shell. The slide rail is provided with a first notch and a second notch that are matched with the two sets of rollers. When the inserting rod on one side of the upper shell is inserted into the joint at the top end of the main support rod, the two sets of rollers respectively move to one side of the first notch and the second notch. Rotate the auxiliary support rod to deflect the auxiliary support rod to the side of the upper shell away from the main support rod. During the process that the auxiliary support rod approaches the main support rod, the inserting rod on the other side of the upper shell can be inserted into the joint at the top end of the auxiliary support rod.

[0008] As a further scheme of the present invention: the main support rod is arranged perpendicular to the wall, and the main support rod can deflect downward relative to the wall. The main support rod and the auxiliary support rod are elastically connected through a telescopic assembly, and the auxiliary support rod can rotate around the main support rod.

[0009] As a further scheme of the present invention: the telescopic assembly includes a slide rod and a sliding sleeve sleeved outside the slide rod. A tension spring is arranged between the inner end face of the sliding sleeve and the slide rod. The sliding sleeve is detachably connected to the auxiliary support rod, and one end of the slide rod is hinged to the main support rod.

[0010] As a further scheme of the present invention: a track is arranged on one side of the main support rod, and a straight groove and an arc groove that are communicated with each other are arranged on the track. A vertical rod is fixedly arranged at the bottom end of the auxiliary support rod, and the bottom end of the vertical rod slides in the arc groove.

[0011] As a further scheme of the present invention: the slide rail is fixed to the top wall of the computer room through a suspension rod.

[0012] As a further scheme of the present invention: a connection groove that is matched with the slide rod is arranged on the main support rod, a vertical shaft is fixedly arranged in the connection groove, and the vertical shaft passes through the slide rod and is rotationally matched with the slide rod.

[0013] As a further scheme of the present invention: a protrusion is fixedly arranged on the inner side surface of the auxiliary support rod, a plug pin is slidably assembled at the protrusion, and a through hole is arranged through the sliding sleeve. When the plug pin is inserted into the through hole, the sliding sleeve is connected to the auxiliary support rod.

[0014] As a further scheme of the present invention: a positioning block is fixedly arranged on the side of the wall close to the main support rod. When the main support rod is in a vertical state, the main support rod can be attached to the positioning block, and a screw rod is threadedly connected to the main support rod. One end of the screw rod can be inserted into the positioning block and is threadedly matched with the positioning block. A connecting rod is fixedly arranged at the position of the wall at the bottom end of the main support rod, and the bottom end of the main support rod is hinged to the connecting rod.

[0015] As a further solution of the present invention: brackets are fixedly installed on both the left and right sides of the top of the upper shell, the brackets are in contact with the slide rails, and rollers are rotatably installed on the brackets.

[0016] A method of using the above monitoring device for the computer room for monitoring includes the following steps: driving the upper shell to slide along the slide rail, so as to monitor the equipment in the computer room on a horizontal plane; driving the lower shell to move in the vertical direction through the lifting component between the upper shell and the lower shell, so that the camera unit can monitor the equipment in the computer room in the vertical direction.

[0017] Compared with the prior art, the beneficial effects of the present invention are: through the main support rod and the auxiliary support rod provided in this device, the upper shell can be supported, so that before the two groups of rollers coincide with the first notch and the second notch, the upper shell can be stably held between the main support rod and the auxiliary support rod, and during the subsequent process of driving the auxiliary support rod to deflect, the upper shell can gradually descend, and then the upper shell can be detached from the slide rail. Through this structure, the upper shell can be quickly detached, and both the auxiliary support rod and the main support rod are arranged in contact with the wall, without occupying the space of the computer room, so that this device can adapt to more scenarios.

Specific implementation manner

[0020] As Figures 1 - 10 shown, a monitoring device and monitoring method for a computer room include a slide rail 1 and an upper housing 2 sliding below the slide rail 1. A lower housing 4 is arranged below the upper housing 2, and a camera unit 401 is installed on the lower housing 4. The upper housing 2 and the lower housing 4 are connected by a lifting assembly, so that the camera unit 401 (which can be a camera) can move in the vertical direction, which is beneficial to monitoring the equipment in the computer room.

[0021] In order to install the upper housing 2 on the slide rail 1, brackets 6 are fixedly installed on the left and right sides of the top of the upper housing 2 in this solution. The brackets 6 can be attached to the slide rail 1, and a roller 601 is rotatably connected to the side of the bracket 6 close to the slide rail 1 through a bearing. The roller 601 rolls on the top of the slide rail 1, and through this structure, the upper housing 2 and the slide rail 1 can be stably matched.

[0022] Combined with Figures 1 - 5 shown, a pair of main support rods 7 are arranged at one end of the slide rail 1. In the initial state, the main support rods 7 are arranged perpendicular to the wall, and the main support rods 7 can deflect downward relative to the wall. Sub-support rods 8 are arranged on both sides of the main support rods 7. In the initial state, the sub-support rods 8 are also in a state perpendicular to the wall, and the sub-support rods 8 can rotate around the main support rods 7; Furthermore, joints 9 are hinged at the top ends of the main support rods 7 and the sub-support rods 8. A jack 901 is opened on the end face of one end of the joint 9. Combined with Figure 1As shown, plug rods 3 that match the jacks 901 are fixedly arranged on both the left and right sides of the upper housing 2. When the upper housing 2 slides to one side of the main support rod 7, the plug rod 3 on one side of the upper housing 2 can be inserted into the jack 901 of the top joint 9 of the main support rod 7. When the secondary support rod 8 rotates 90° around the main support rod 7, the main support rod 7 and the secondary support rod 8 can be aligned with each other, and the jack 901 of the top joint 9 of the secondary support rod 8 can be aligned with the plug rod 3 on the other side of the upper housing 2. So that during the process of the secondary support rod 8 approaching the main support rod 7, the plug rod 3 on the other side of the upper housing 2 can be inserted into the jack 901 of the top joint 9 of the secondary support rod 8. At this time, the upper housing 2 can be stably supported by the main support rod 7 and the secondary support rod 8, thus preparing for the removal of the upper housing 2.

[0023] In order to facilitate the separation of the upper housing 2 from the slide rail 1, the slide rail 1 in this solution is of a T-shaped structure, and a first notch 102 and a second notch 103 are respectively formed at the two wing positions of the slide rail 1. Specifically, refer to Figure 3 As shown, during actual use, the two sets of rollers 601 on the upper housing 2 can simultaneously move to the positions of the first notch 102 and the second notch 103, so that the two sets of rollers 601 can be separated from the slide rail 1 simultaneously.

[0024] During actual use, the main support rod 7 and the secondary support rod 8 are elastically connected, so that the secondary support rod 8 can move towards the direction close to the main support rod 7 after rotating 90° along the track 12 embedded in the ground. Specifically, when the upper housing 2 needs to be disassembled, the upper housing 2 can be driven to move towards the direction close to the main support rod 7. When the two sets of rollers 601 on the top of the upper housing 2 move to one side of the first notch 102 and the second notch 103, the movement of the upper housing 2 can be stopped. At this time, the plug rod 3 on one side of the upper housing 2 can be inserted into the jack 901 of the top joint 9 of the main support rod 7. Then, the staff can rotate the secondary support rod 8. When the secondary support rod 8 rotates 90° along the track 12, it can be aligned with the main support rod 7, and the upper housing 2 can be located between the main support rod 7 and the secondary support rod 8. Specifically, refer to Figure 3 As shown, since the main support rod 7 and the secondary support rod 8 are elastically connected, therefore, under the action of the elastic force, the secondary support rod 8 can move towards the direction close to the main support rod 7, so that the joint 9 at the top of the secondary support rod 8 can be inserted and connected with the plug rod 3 on the other side of the upper housing 2. Thus, the upper housing 2 is inserted and connected between the main support rod 7 and the secondary support rod 8; Afterwards, the upper shell 2 is driven to move along the slide rail 1 again so that the upper shell 2 continues to approach the main support rod 7. During this process, the secondary support rod 8 can move synchronously with the upper shell 2, so that the upper shell 2 is always clamped between the main support rod 7 and the secondary support rod 8 without being separated from the two. In addition, during this process, the rollers 601 on both sides of the top of the upper shell 2 can move to the first notch 102 and the second notch 103, so that the upper shell 2 can move downward relative to the slide rail 1. Here, the lengths of the first notch 102 and the second notch 103 are greater than the outer diameter of the roller 601, so as to provide conditions for the roller 601 to pass through the first notch 102 and the second notch 103 downward; Reference Figures 3 - 4 , Figure 6 As shown, when the two sets of rollers 601 move to the first notch 102 and the second notch 103, the staff can pull the secondary support rod 8 outward to make the secondary support rod 8 deflect downward. Figure 6 As shown, since the main support rod 7 can also deflect relative to the wall, when the secondary support rod 8 is pulled outward, the main support rod 7 and the secondary support rod 8 will deflect as shown in FIG. Figure 6 The "eight"-shaped structure shown enables the upper shell 2 to gradually move downward relative to the slide rail 1, which is convenient for the staff to repair and maintain the upper shell 2 and the lower shell 4; When the upper shell 2 needs to be reinstalled on the slide rail 1, the secondary support rod 8 can be pushed to deflect it upward. During this process, the upper shell 2 can move upward so that the rollers 601 are above the two wings of the slide rail 1, driving the upper shell 2 in the direction away from the wall, so that the two sets of rollers 601 respectively leave the first slot 102 and the second slot 103 and fall onto the slide rail 1 to stop the sliding of the upper shell 2. During this process, the insertion rods 3 on both sides of the upper shell 2 are in the insertion holes 901. The staff pulls the secondary support rod 8 to disconnect it from the upper shell 2 and rotates the secondary support rod 8 to reset it. At this point, the rollers 601 move to the slide rail 1, so that the upper shell 2 can slide along the slide rail 1.

[0025] To sum up, this device can support the upper shell 2 by means of the main support rod 7 and the auxiliary support rod 8, so that before the two sets of rollers 601 overlap with the first slot 102 and the second slot 103, the upper shell 2 can be stably maintained between the main support rod 7 and the auxiliary support rod 8, and in the subsequent process of driving the auxiliary support rod 8 to deflect, the upper shell 2 can gradually descend, and then the upper shell 2 can be removed from the slide rail 1. Through this structure, the upper shell 2 can be quickly disassembled, and the auxiliary support rod 8 and the main support rod 7 are both arranged close to the wall and will not occupy the space in the computer room, so that this device can adapt to more scenarios.

[0026] Combination Figures 1 - 2As shown in the figure, a positioning block 11 is fixedly arranged on one side of the wall close to the main support rod 7. When the main support rod 7 is in a vertical state, the main support rod 7 can be attached to the positioning block 11, and a screw rod 10 is threadedly connected to the main support rod 7. One end of the screw rod 10 can be inserted into the positioning block 11 and is in threaded cooperation with the positioning block 11. Through the cooperation of the screw rod 10 and the positioning block 11, the stability of the main support rod 7 in the vertical state can be maintained. Combining Figure 1 As shown in the figure, a connecting rod 702 is fixedly arranged at the position of the bottom end of the main support rod 7 on the wall, and a circular shaft is fixedly arranged on the main support rod 7. The circular shaft passes through the connecting rod 702 and is rotationally matched with it through a bearing; Furthermore, combining Figures 3 - 5 As shown in the figure, the main support rod 7 and the auxiliary support rod 8 are connected by a telescopic assembly. Specifically, the telescopic assembly includes a sliding rod 701 and a sliding sleeve 801 slidably sleeved outside the sliding rod 701. A tension spring 16 is connected between the inner end face of the sliding sleeve 801 and the sliding rod 701. A connecting groove 703 matched with the sliding rod 701 is formed on the main support rod 7. A vertical shaft is fixedly arranged in the connecting groove 703, and the vertical shaft passes through the sliding rod 701 and is rotationally matched with it. A protrusion 15 is fixedly arranged on the inner side face of the auxiliary support rod 8, and a pin 14 is slidably assembled at the protrusion 15. A through hole is formed through the sliding sleeve 801. When the pin 14 is inserted into the through hole, the sliding sleeve 801 is connected to the auxiliary support rod 8. Through this structure, the sliding sleeve 801 and the auxiliary support rod 8 are detachably connected. During actual use, the screw rod 10 is rotated to disengage it from the positioning block 11, and the pin 14 is pulled out to disengage it from the sliding sleeve 801. Then, the main support rod 7 and the auxiliary support rod 8 can be driven to deflect downward to drive the upper housing 2 to move downward.

[0027] Furthermore, a straight groove 1201 and an arc groove 1202 that are communicated with each other are arranged on the track 12. The bottom end of the auxiliary support rod 8 is fixedly provided with a vertical rod 802, and the bottom end of the vertical rod 802 slides in the arc groove 1202. The center of the arc groove 1202 is on the axis of the vertical shaft. During the process of driving the auxiliary support rod 8 to deflect, the vertical rod 802 can slide along the arc groove 1202. When the vertical rod 802 slides to the straight groove 1201, it stops sliding. At this time, the main support rod 7 and the auxiliary support rod 8 are in an aligned state, and the auxiliary support rod 8 can gradually approach the main support rod 7 along the straight groove 1201. Similarly, when it is necessary to drive the auxiliary support rod 8 to reset, as long as the auxiliary support rod 8 is pulled to align the vertical rod 802 with the arc groove 1202, the auxiliary support rod 8 can be driven to reset. During actual operation, the length of the straight groove 1201 can be determined according to the degree of downward deflection of the auxiliary support rod 8. When the vertical rod 802 abuts against the end of the straight groove 1201 far from the wall, the auxiliary support rod 8 deflects downward to the limit position.

[0028] Referring to Figure 1As shown, the slide rail 1 is fixed to the top wall of the machine room through a suspension rod.

[0029] Reference Figures 1 - 4 , Figure 8 As shown, a gear 17 is rotatably installed at the top position of the upper shell 2 through a support frame. Specifically, a connecting shaft 1701 is fixedly installed on the gear 17, and the connecting shaft 1701 passes through the support frame and rotates with it, and a rack 101 meshing with the gear 17 is fixedly installed at the bottom of the slide rail 1. A driving motor is arranged in the upper shell 2, and the driving motor is transmission-connected with the connecting shaft 1701 on the gear 17, so as to drive the gear 17 to rotate, thereby driving the upper shell 2 to move along the slide rail 1.

[0030] Combination Figures 3 - 4 As shown, in actual use, a detection unit 13 can be fixedly installed on the top of the slide rail 1. The detection unit 13 can be an infrared sensor or an ultrasonic sensor. The position of the front group of rollers 601 can be detected through the detection unit 13. Of course, the detection unit 13 can be used to control the sound and light alarm on the slide rail 1. When the two groups of rollers 601 move to the side of the first slot 102 and the second slot 103, the front roller 601 can be detected and the sound and light alarm can be triggered through the detection unit 13, thereby reminding the staff to stop the operation of the upper shell 2. Of course, the detection unit 13 can also be used to directly control the drive motor.

[0031] Reference Figure 7 As shown, the depth of the second slot 103 is greater than the depth of the first slot 102. The rear group of rollers 601 can be aligned with the first slot 102 when moving, while the front group of rollers 601 can be aligned with the second slot 103 and avoid the first slot 102 when moving. Through this structure, the two groups of rollers 601 can be disengaged from the slide rail 1 at the same time.

[0032] Combination Figures 1 - 3 , Figures 9 - 10 As shown, a base is fixedly provided at the top end of the main support rod 7 and the auxiliary support rod 8, and a hinge block is fixedly provided on the side of the joint 9 close to the base. Specifically, a hinge shaft 19 is fixedly provided at the hinge block, so that the hinge shaft 19 passes through the base and rotates with it, and a torsion unit 1901 (which can be a torsion spring or a coil spring) is sleeved on the outside of the hinge shaft 19, and both ends of the torsion unit 1901 are respectively connected to the hinge shaft 19 and the base, so that in the initial state, the side of the joint 9 close to the base can be in contact with the side of the main support rod 7 or the auxiliary support rod 8, so as to maintain the stability of the joint 9.

[0033] like Figures 1 - 5 , Figures 9 - 11As shown in the figure, fixed frames 18 are fixedly arranged on the top surfaces of the main support rod 7 and the auxiliary support rod 8. A positioning rod 21 is elastically connected to the fixed frame 18. Specifically, an installation groove is formed in the bottom surface of the fixed frame 18. The positioning rod 21 is of a T-shaped structure and passes through the fixed frame 18 and the joint 9 and is slidably matched with both. A spring is arranged between the bottom surface of the inner part of the installation groove and the protruding part at the top end of the positioning rod 21. And an electromagnet 20 is fixedly arranged on the top surface of the inner part of the installation groove. The positioning rod 21 is made of iron. A chamfer 302 is arranged at one end face of the inserting rod 3, and a circular hole 301 matched with the positioning rod 21 is formed in the outer peripheral wall of the inserting rod 3. When the inserting rod 3 is inserted into the inserting hole 901, the positioning rod 21 can be extruded by the chamfer 302 to move upward. When the positioning rod 21 is aligned with the circular hole 301 and inserted into the circular hole 301, the joint 9 and the inserting rod 3 can be kept stable. In addition, switches for controlling the electromagnet 20 are installed on both the main support rod 7 and the auxiliary support rod 8, so that the switches are electrically connected to the electromagnet 20. During the process of installing the upper shell 2 on the slide rail 1, the electromagnet 20 can be powered on and adsorb the positioning block 11, so that one end of the positioning block 11 can move out of the circular hole 301.

[0034] In actual use, a protection unit 5 can be fixed between the upper shell 2 and the lower shell 4. The protection unit 5 can be a corrugated pipe. The lifting assembly can be an electric telescopic rod to drive the lifting of the lower shell 4. Or a scissor lift structure can be installed between the upper shell 2 and the lower shell 4, and the electric telescopic rod is used to drive the scissor lift structure to expand or fold. Since it is a mature technical means in the mechanical field, it will not be elaborated here.
