[0037] Example:

[0038] The utility model proposes a monitoring device for a nuclear power plant loading and unloading machine, which belongs to a closed-circuit television system for the loading and unloading machine. Figure 3Specifically, the monitoring device includes a camera 6, a connection box assembly and a bracket assembly. The camera 6 is generally a dome camera. The bracket assembly is fixed on the loading and unloading machine, and the camera 6 and the connection box assembly are first assembled into a whole, as shown in FIG. Figure 1 As shown, the whole is then installed on the bracket assembly.

[0039] like Figure 1 As shown, the connection box assembly includes a connection box 1 and a connection portion, the connection box 1 is connected to the connection portion, and the connection box 1 is detachably connected to the camera 6. Specifically, the bottom of the connection box 1 is fastened to the top of the camera 6 via a first locking assembly, at least a portion of the top of the camera 6 is located within the connection box 1, and the portion of the camera 6 located within the connection box 1 is fastened to the connection box 1 via a second locking assembly.

[0040] Preferably, the first locking assembly includes a top thread and a threaded hole. The top thread is provided at the top of the housing of the camera 6, and the threaded hole is provided at the bottom of the connection box 1. The threaded hole and the top thread are matingly connected. The second locking assembly includes an internal nut 7. The internal nut 7 is located inside the connection box 1 and is matingly connected to the top thread. By designing the connection between the connection box 1 and the camera 6 to adopt a double locking method, the connection between the camera and the connection box is ensured to be stable and not loose.

[0041] The bottom of the connection box 1 also features a cable hole, through which the camera 6's cable enters the connection box 1. A quick-disconnect connector is also provided on the connection box 1, to which the camera's cable connects. The quick-disconnect connector on the connection box 1 serves as the electrical interface for the camera 6, connecting to an external cable. This facilitates electrical connection during installation and removal from the bracket assembly.

[0042] Combine Figure 2 and Figure 3 As shown, the bracket assembly includes a bracket body 8 and a locking part. The locking part is arranged on the bracket body 8. The bracket body 8 is generally permanently fixed to the loader trolley structure through the tail bolt. The locking part can lock the connecting part of the connecting box assembly on the bracket assembly.

[0043] The locking portion includes a locking member, the position of which can be moved so that the locking portion is in the following positions: Figure 3 The locked state shown and Figure 2 In the open state, the connection box assembly and the camera 6 can be removed from the bracket assembly as a whole.

[0044] By providing a connection box and a locking portion, the connection box assembly and the spherical camera can be quickly and conveniently installed and disassembled on the bracket assembly as a whole, while meeting multiple requirements such as matching the mechanical and electrical interfaces for installing and disassembling the spherical camera, thereby meeting the actual needs of the closed-circuit television system of the nuclear power plant loading and unloading machine.

[0045] Specifically, the connection section includes a connecting plate 2, which is fixedly connected to the top of the connection box 1. The locking section defines two or more positioning holes 9. In the locked state, the connecting plate 2 is positioned above the positioning holes 9 and below the locking member. The connection section also includes two or more positioning members, which are fixed to the connecting plate 2 and plug into and mate with the two or more positioning holes 9. This plug-in positioning ensures accurate positioning of the dome camera during installation, ensuring the proper operation of the monitoring device.

[0046] The connection also includes a vibration damping block 5, which is mounted on the positioning member. In the locked state, the vibration damping block 5 is located between the connecting plate 2 and the positioning hole 9. The vibration damping block 5 is made of an elastic material to filter out vibrations during the operation of the spherical camera, ensuring image stability and quality.

[0047] Preferably, the positioning member is configured as a positioning bolt 4. Both ends of the connecting plate 2 along the length direction extend beyond the length of the connecting box 1. Two positioning bolts 4 are provided at both ends of the connecting plate 2, and the positioning bolts 4 are fixed to the connecting plate 2.

[0048] Preferably, the connection portion further comprises a handle 3, which is fixed above the connection plate 2 and disposed between the two positioning bolts 4. The handle 3 provides a good human-machine interface, facilitating the movement of the camera 6 and the connection box assembly as a whole.

[0049] The locking portion includes baffles 11, which are provided as locking members in the form of pressure rods 10. Baffles 11 are positioned on either side of the positioning hole 9, and are positioned on both sides of the width of the connecting plate 2. In the locked state, the pressure rods 10 pass through the baffles 11 on both sides, pressing the connecting plate 2 tightly. Preferably, multiple baffles 11 can be designed as an integrated structure with the bracket body 8.

[0050] Preferably, a key slot is provided on the baffle 11, and a key 12 is provided at the end of the pressure rod 10. The key 12 cooperates with the key slot so that the pressure rod 10 can exit the baffle 11 to enter the open state and can prevent the pressure rod 10 from detaching and falling from the baffle 11.

[0051] Specifically, during installation, after the camera 6 and the connection box assembly are plugged and positioned on the bracket assembly, the end of the pressure rod 10 is inserted into the other side of the baffle through the keyway, and the pressure rod 10 is rotated to prevent it from detaching and falling. During disassembly, the two pressure rods 10 are moved, and the quick-disconnect connector on the connection box 1 is disconnected, and the carrying handle 3 can be removed as a whole. This design ensures a secure installation of the connection box assembly and the bracket assembly, reduces the risk of falling off, and ensures safe and convenient assembly and disassembly.
