The invention provides a dual camera monitoring and control system. The system includes a high sensitivity monochrome camera with enhanced infrared response, an array of infrared illuminators for zero ambient light monitoring, and a color camera that does not require enhancement in the infrared spectrum. The system also includes ambient light intensity perception, video signal exchange technology and energy conversion circuits. The system combines optimal monochrome imaging in low-light or no-light conditions with optimal color tinted imaging in high ambient light conditions, both for high-quality image clarity. The dual-camera feature of the system is evident to the user due to the integrated automated control of the system, which also reduces energy consumption, thus making the system suitable for wireless, remote, self-sufficient systems that operate from surrounding The environment gains energy.

The invention relates to the field of cable maintenance, in particular to a cable repairing device and a cable repairing method. The cable repairing device includes a repairing shell, including two split shells, one adjacent side of the two shells is hinged, and the other is adjacent The sides can be connected by a locking device. One of the two sub-shells is provided with a glue injection hole. After the repair shells are combined, a cable passing cavity with openings at both ends is formed. The inner diameter of the passing cavity is larger than the outer diameter of the cable to be repaired. The cable repair method is to cover the repaired sheath on the damaged cable sheath, and the two ends of the repaired sheath are respectively placed on the cable insulation sheath at both ends of the damaged cable sheath and sealed with it, and the liquid repair glue is injected through the glue injection hole. , after the repair glue is solidified, it can be used as the repair layer of the damaged cable sheath together with the repair shell; the beneficial effects of the invention are: simple structure, convenient use, good waterproof and moisture-proof performance, and high strength and not easy to break.

The protective device comprises: a movable device of the imager with a probe, an electrical driven rotating device and a probe movable device; a motorized ball valve sealing device with a valve, a sealing sleeve, an auto-clamp device, and a location switch; a gas protection device with a transient sleeve and an inlet for cooling gas, and a straight plate valve cleaning device with a baffle plate valve and an observe window. This invention improves device performance.

The invention discloses a gear lubricant, which is prepared from the following raw materials in parts by weight: base oil comprising 5-15 parts of esters, 30-50 parts of hydrocarbon and 30-40 parts of three-type base oil, an additive comprising 3-10 parts of an extreme pressure antiwear agent, 2-4 parts of a cleaning agent, 4-6 parts of an oxidation and corrosion inhibitor and 3-8 parts of an anti-friction agent. The esters is one or more of NP343, NP372 and P81, the hydrocarbon is one or more of PA08, PA010 and PA012, the three-type base oil is one or more of 150NN, 100N, 75N and 250N, the extreme pressure antiwear agent is one or more of T323, T321 and T306, the cleaning agent is one or more of T101, T104 and T105, the oxidation and corrosion inhibitor is one or two of T203 and T204, and the anti-friction agent is boron nitrogen compound. The invention has excellent high temperature stability, antioxidation stability, wear-resistance, corrosion resistance and rust resistance. The gear lubricant is added into various gear oil according to the proportion, the viscosity or the viscosity index of the gear oil is slightly changed or not changed, so that the wear resistant, high temperature resistant and press resistant boundary lubricating oil film is formed rapidly when an apparatus is at high speed, low speed, heavy load or impact load.

The invention relates to a non-metal high-temperature resistant expansion joint for a slag discharge pipeline of a boiler, belonging to the technical field of conveying pipelines. The non-metal expansion joint comprises an rectangular upper frame and a rectangular lower frame which are respectively connected to an upper pipeline and a lower pipeline; the flow area of the upper frame is smaller than that of the lower frame, the average spacing between the circumference of the upper frame and the circumference of the lower frame is 1-1.5 times that of the axial displacement, a lower horizontal turnup flange is arranged on the circumference of the upper frame, an upper horizontal turnup flange is arranged on the circumference of the lower frame, a concentric-shaped flexible ring strip is fixed between the upper horizontal turnup flange and the lower horizontal turnup flange, and a concentric-shaped heat insulation layer is fixed at the inner side of the flexible ring strip. The expansion joint structure which radially extends, disclosed by the invention, breaks through the traditional expansion joint which axially extends. The non-metal high-temperature resistant expansion joint disclosed by the invention effectively overcomes the defect that an internal heat insulation layer of the conventional non-metal expansion joint of the slag discharge pipe of the boiler is incapable of resetting due to large compression displacement and can effectively operate for a long time. In addition, the concentric-shaped structure can absorb larger axial displacement within a shorter axial length and is very compact in structure.
