Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fire monitoring technology, and specifically relates to a fire monitoring device. Background Technology
[0002] In the construction of fire safety projects inside buildings, the installation of fire monitoring equipment is particularly important. Fire monitoring often uses video surveillance and sensors to monitor abnormal temperatures and smoke.
[0003] In related existing technologies, such as Chinese Patent No. CN222047325U, an adjustable fire protection maintenance monitoring device is disclosed. This solution uses a hydraulic rod to drive a connecting block to move, thereby causing the rotating rod to rotate under the restriction of the connecting rod. This allows the locking block to be locked into the groove, fixing the connected camera and achieving easy disassembly. This reduces the duration of monitoring failure during maintenance and increases the safety of use.
[0004] However, in actual use, the rotating rod, connecting rod, connecting block, and hydraulic rod two form a crank-slider structure, and the locking block is installed on the rotating rod. Although the connecting block two and the mounting block can be installed together by locking the locking block inside the groove two, the hydraulic rod two needs to provide load-bearing force at all times to maintain the stability of the locking block position. After long-term use, when the hydraulic rod two fails, it may not be able to provide sufficient load-bearing force to maintain the stability of the locking block position. At this time, the locking block will cause the crank-slider structure to rotate under the pressure of the weight of the parts below, causing the connecting block two to detach from the locking block. At this time, the connecting block two and the parts below will fall, resulting in more serious economic losses. In summary, the reliability of the connecting parts in the above solution is poor and it is not conducive to practical use. Utility Model Content
[0005] The present invention aims to provide a fire monitoring device to solve the problem of poor reliability of the connectors in existing fire monitoring devices mentioned above.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a fire monitoring device, including a connecting shaft installed on the main body of a building, a connecting block fixed at the lower end of the side wall of the connecting shaft, and a connecting hole provided on the side wall of the connecting shaft;
[0007] The mounting block has a socket on the top, a slot around the circumference of the socket, and an arc-shaped groove around the bottom of the socket. The groove is connected to the slot, the connecting shaft is adapted to the socket, and the connecting block is adapted to both the slot and the groove.
[0008] The limiting rod is slidably inserted into the side wall of the mounting block, and the end of the limiting rod extends into the connecting hole;
[0009] The monitoring unit is installed at the bottom of the mounting block.
[0010] The principle and effects of this technical solution:
[0011] 1. By adapting the connecting blocks of the connecting shaft to the slots and rotating grooves respectively, the mounting block can be fitted onto the connecting shaft. By rotating, the connecting block is misaligned with the slot, allowing the mounting block to be attached to the connecting shaft. The limiting rod inserted into the connecting hole limits the connecting shaft, preventing it from rotating under no external force. This ensures the stability between the connecting shaft and the mounting block. Furthermore, even if the connecting block or the limiting rod is damaged, the monitoring device will not fall off the wall and break, improving the durability and reliability of the device.
[0012] 2. During subsequent installation and maintenance, it is only necessary to release the limit rod from the connection hole, and the connecting shaft can be separated from the mounting block by rotation. The operation is simple and convenient, and the reliability is high.
[0013] The present invention is further configured to include a stabilizing unit, which includes a stabilizing cylinder, a pressure plate, and a spring. The stabilizing cylinder is fixed to the side wall of the mounting block, and the limiting rod is slidably inserted into the stabilizing cylinder. The pressure plate is slidably fitted inside the stabilizing cylinder and is fixedly mounted on the limiting rod. The spring is installed inside the stabilizing cylinder and is located on the side of the pressure plate away from the mounting block.
[0014] The principle and effect of this technical solution: By setting up a stabilizing cylinder, pressure plate and spring, the limiting rod can be stably inserted into the connecting hole under the elastic force of the spring, so as to limit the connecting shaft and avoid the limiting rod from slipping out of the connecting hole due to vibration, shaking and other factors, thus improving the stability of the device.
[0015] The present invention is further configured such that: the end of the limiting rod away from the mounting block has a protruding edge, and the protruding edge slides in cooperation with the stabilizing cylinder.
[0016] The principle and effect of this technical solution are as follows: When the protruding edge moves away from the stabilizing cylinder along with the limiting rod, after the protruding edge has completely left the stabilizing cylinder, the limiting rod has completely left the connecting hole of the connecting shaft. By rotating the limiting rod, the protruding edge and the stabilizing cylinder can be misaligned. At this time, when the limiting rod is released, the protruding edge will not automatically return to its original position, which makes it easier for workers to disassemble and assemble the mounting block. During installation, after the connecting shaft is in place, the limiting rod can be rotated to align the protruding edge with the stabilizing cylinder, and the limiting rod can automatically return to its original position under the action of the spring, which facilitates subsequent disassembly and maintenance.
[0017] The present invention is further configured as follows: the monitoring mechanism includes a mounting plate, a mounting frame, a first motor, a first rotating shaft, an outer sleeve, a fixing frame, and a camera body. The mounting plate is fixed to the bottom of the mounting block, the mounting frame is fixed to the bottom of the mounting plate, the first motor is mounted on the mounting frame, the top of the first rotating shaft passes through the mounting frame and is connected to the movable end of the first motor, the bottom of the first rotating shaft is connected to the fixing frame, the two ends of the outer sleeve are rotatably connected to the mounting frame and the fixing frame respectively, and the outer sleeve and the first rotating shaft are coaxially distributed. The camera body is mounted on the fixing frame.
[0018] The principle and effect of this technical solution: The first motor drives the first rotating shaft to rotate, which in turn drives the fixed frame to rotate, thereby causing the fixed frame to rotate the camera body. This allows the camera body to adjust its angle in the horizontal direction, thereby increasing the monitoring range. Furthermore, the connection between the mounting bracket and the fixed frame via the outer sleeve makes the installation and rotation of the fixed frame more stable.
[0019] The present invention is further configured such that: the monitoring mechanism also includes a second motor, a second rotating shaft and a fixed frame, the fixed frame is detachably mounted on the camera body, the two sides of the fixed frame are respectively equipped with second rotating shafts, the second rotating shafts are rotatably connected to the fixed frame, the second motor is fixed on the outer wall of the fixed frame, and the second rotating shaft on one side extends to be connected to the movable end of the second motor.
[0020] The principle and effect of this technical solution: By setting up a second rotating shaft, a second motor and a fixed frame, the second motor can drive the second rotating shaft to rotate, thereby driving the fixed frame to move the camera body to adjust the angle in the vertical direction, so that the camera has more monitoring angles and can monitor a wider range.
[0021] The present invention is further configured such that: the monitoring mechanism also includes a connecting plate and a limiting member, the connecting plate is fixed to the bottom of the camera body and slides with the fixed frame, and the limiting member is installed on the fixed frame and is used to limit the position of the connecting plate.
[0022] The principle and effect of this technical solution: By setting the connecting plate, the camera body can be restricted by the connection plate and the fixed frame after it is installed in the fixed frame, thereby improving the stability of the camera body installed in the fixed frame. In addition, the connecting plate is limited by the limiting component, so that the camera body can be positioned. At the same time, it is easy to disassemble and install, which is beneficial to the later maintenance.
[0023] The present invention is further configured such that: the limiting member is a connecting bolt, the connecting bolt is slidably inserted into the bottom of the fixing frame, and the end of the connecting bolt extends to be threaded into the connecting plate.
[0024] The principle and effect of this technical solution: By threading the connecting bolts into the connecting plate, the connecting bolts can connect the connecting plate and the fixed frame into a whole, thereby positioning the camera body and preventing the camera body from slipping when adjusting the angle.
