This invention provides a ring network structure marine valve remote control and liquid level telemetry system, including a valve remote control data acquisition component and a liquid level telemetry data acquisition component. The valve remote control data acquisition component includes a valve remote control data acquisition box and n electric valve actuators, which are sequentially connected by cables to form a ring network structure. The liquid level telemetry data acquisition component includes a liquid level telemetry data acquisition box and n liquid level telemetry local processing units, which are sequentially connected by cables to form a ring network structure. This invention has the following advantages: The sequential connection of the n electric valve actuators and n liquid level telemetry local processing units to form a ring network structure, along with the redundant design of the ring network structure, not only significantly reduces the amount of cable used but also reduces the workload of cable laying, and ensures that any single point of failure will not cause a failure in all equipment.

This utility model provides a frame and temple assembly structure for eyeglasses, comprising a frame with a first pivot portion on each side, each first pivot portion having a recessed hole and a plurality of first locking teeth around its periphery, and a first elastic groove adjacent to the first locking teeth. The inner surface of the first pivot portion has a tapered bevel. Each temple has a second pivot portion at one end, with a locking post embedded in the recessed hole. The second pivot portion has a plurality of second locking teeth that engage with the first locking teeth. Another temple has a second elastic groove on one end adjacent to the second locking teeth. This allows the second and first elastic grooves to be compressed and retracted respectively when the second and first locking teeth pivot relative to each other, facilitating smooth relative pivoting of the second and first locking teeth.

The invention provides a control method of a lithium-ion nail gun, in a normal working state, a brushless motor of the lithium-ion nail gun continuously rotates forwards, a ratchet wheel drives a reduction gear to rotate forwards, a first limiting column and a second limiting column sequentially abut against a limiting block in the rotating process, a hammer block is continuously pushed to move backwards, and a spring is driven to be compressed; when the second limiting column is separated from the limiting block, the spring returns, the nail is ejected, and the brushless motor rotates to return to the initial position; when the lithium-ion nail gun is interrupted in work and restarted, the control method comprises the following steps: firstly trying to drive the brushless motor to rotate forwards, if the brushless motor cannot rotate forwards, reversing to rotate reversely, so that the hammer block and the firing pin slightly retreat until the hammer block and the firing pin retreat for a preset distance or retreat to an initial working position, stopping retreating, and controlling the brushless motor to rotate forwards, so that the lithium-ion nail gun recovers normal work.

The invention discloses an uninterruptible power supply switching method based on Ethernet and Beidou short message communication, relates to the technical field of uninterruptible power supply switching, and aims to solve the problems of short-time power supply interruption and complex flow of a traditional power supply switching method. Comprising the following steps: setting an IP address, a port number, a subnet mask and a gateway of a power distribution substation in a same network segment or cross-network segment scene, configuring a route during cross-network segment, if a private network and an office network between the power distribution substations do not communicate with each other, additionally arranging a communication front-end processor at a master station, and configuring different VLANs and firewalls to realize data communication. One-to-one NAT is enabled in the firewall to ensure normal communication of services. The method has the advantages that the reliability and safety of uninterrupted power supply switching of the through self-closing line are effectively improved, the quickness of fault isolation in the switching process is guaranteed, and the operation and inspection technical level is improved.

The utility model discloses a hydraulic system for a sanitation cleaning robot, which belongs to the technical field of hydraulic systems and comprises an execution element, a power unit, an integrated control valve group and an emergency manual valve group. The integrated control valve set comprises a second electromagnetic valve, a filter, a pinger, a second overflow valve, a second valve block, a hydraulic lock and an electromagnetic valve inserting hole. The power unit comprises a motor, a hydraulic pump, a first electromagnetic valve, a first overflow valve, a first valve block, a hydraulic oil tank and a first one-way valve. Through the above mode, the motor can be started in a no-load or light-load state without causing motor faults, when the motor is started and operates stably, the motor can be switched to a normal mode, and power supply faults caused by overlarge starting current are avoided. According to the utility model, manual operation can be realized, so that an emergency function can be realized when a system breaks down.
