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.

The utility model discloses a heat exchanger which comprises a device shell and further comprises an observation opening, a heat exchanger, a heat exchanger and a heat exchanger, the connecting mechanism is arranged on one side of the observation opening; the observation mechanism is connected with the connecting mechanism, the observation mechanism is rotatably connected with the device shell through the connecting mechanism, and the observation mechanism rotates between a first position and a second position; when the observation mechanism rotates to the first position, the observation mechanism covers the observation opening; when the observation mechanism rotates to the second position, the observation opening is opened; the observation mechanism comprises an observation plate; the lock catch mechanism is arranged on the connecting mechanism and / or the observation mechanism, and the lock catch mechanism is used for locking the observation mechanism when the observation mechanism rotates to the first position; and the cleaning mechanism is arranged on the inner side of the observation mechanism and used for cleaning the surface of the observation plate. The condition in the device shell of the heat exchanger can be conveniently observed.

The invention relates to a semi-open-close type hopper transfer cart for a production line. The semi-open-close type hopper transfer cart is used for conveying bulk materials in batches or bulk material formed lumps on the production line and automatically discharging and feeding. According to the semi-open-close type hopper transfer cart for the production line, bulk materials or formed lumps of the bulk materials in batches on the production line are effectively conveyed, automatic discharging is achieved, and feeding is accurate. Transfer cart driving wheels are installed below the cart body chassis and walk on a wheel rail of a material conveying structure of a production line, and the semi-open-close type coaming and the fixed coaming on the cart body chassis are matched with the movable bottom pulling plate so as to complete the work of bearing, conveying and automatic discharging of bulk materials or formed lumps of the bulk materials. The bulk materials are not piled up after being unloaded through the controlled movable bottom pulling plate; the semi-open-close type hopper movable coaming can be opened and closed, the semi-open-close type hopper movable coaming and the hopper fixed coaming clamp bulk materials to form lumps so that the lumps can deform slightly, the semi-open-close type hopper movable coaming and the hopper fixed coaming can be matched with the movable bottom pulling plate so that discharging can not be blocked, smooth operation of a production line for batch feeding is met, and the work efficiency is improved.

The present utility model relates to a medicine bottle with an outlet needle, including a main bottle body, an end of the main bottle body being provided with an outlet needle, and the outlet needle communicating with an inner cavity of the main bottle body; further including a sub-bottle body, an end of the sub-bottle body being connected with an end cover, and the end of the sub-bottle body corresponding to the end cover having a male-connection structure, an end of the main bottle body away from the outlet needle having a female-connection structure, the male-connection structure being adapted to the female-connection structure, a connection between the sub-bottle body and the main bottle body being a fixed and sealed connection after the end cover is removed and the male-connection structure of the sub-bottle body is connected to the female-connection structure of the main bottle body, and the sub-bottle body communicating with the inner cavity of the main bottle body.

The invention relates to a monitoring device (8) of a slipform paver for monitoring the compaction of concrete placed in a slipform of the slipform paver by at least one concrete compaction device (7) having a hydraulic motor (19) for driving an imbalance of the generated vibrations. Furthermore, the invention relates to a method for monitoring the compaction of concrete placed in a slipform of a slipform paver by means of at least one concrete compaction device having a hydraulic motor for driving a vibration-generating imbalance. The monitoring device (8) according to the invention and the method according to the invention are characterized in that the pressure in the hydraulic fluid system (11) is measured by at least one pressure sensor (25.1, 25.2, 25.3, 25.4) arranged in the hydraulic fluid system (11), which generates a pressure signal dependent on the pressure in the hydraulic fluid, and a conclusion of compaction of the concrete placed in the slip form is obtained based on analysis of the pressure signal.
