The utility model discloses a portable gas sampler and relates to the technical field of gas sampling. The device comprises a collecting cylinder, a sealing plate is arranged at one end of the collecting cylinder, a piston rod is movably inserted into the collecting cylinder, a first through hole and a second through hole are formed in the sealing plate in a penetrating mode, the first through hole is communicated with the collecting cylinder, and the end, close to the sealing plate, of the collecting cylinder is communicated with a collecting pipe; when gas is collected, the piston rod is completely inserted into the collecting cylinder, then the collecting cylinder is inserted into the collecting bottle, gas carried in the collecting bottle can be exhausted through the second through hole along with insertion of the collecting cylinder, and after the gas carried in the collecting bottle is exhausted, the second through hole is plugged through the plugging piece, so that the gas is collected. Then the piston rod is drawn to slide in a reciprocating manner, under the cooperation of the two one-way valves, the collected gas sample is conveyed into the collection bottle, the gas in the collection bottle is emptied firstly, and then the collected gas sample is filled, so that the subsequent monitoring result is ensured.

This invention discloses an external water filling device for gas-liquid displacement in a sealed cooling water tank of laser equipment. It includes a transparent external container, a dual-port sealing cover, an inlet pipe, an exhaust pipe, an inlet check valve, an exhaust check valve, and a float-type air pipe assembly. The dual-port sealing cover has a first port and a second port that are isolated from each other. The first port is connected to the liquid filling port of the sealed cooling water tank via the inlet pipe and the inlet check valve. The second port is connected to the exhaust port of the sealed cooling water tank via the exhaust pipe and the exhaust check valve. The float-type air pipe assembly keeps the air inlet end of the air pipe above the liquid level in the container. During liquid filling, liquid enters the water tank through the inlet channel, and gas from the water tank enters the gas phase space of the container through the exhaust channel, achieving gas-liquid displacement. The device can also achieve backflow observation through a detachable switching structure, a parallel reflux bypass branch, or a three-way switching valve, facilitating the assessment of coolant contamination status.

The utility model relates to the technical field of water conservancy experiment detection soil sampling, and particularly discloses a water conservancy experiment detection soil sampling device which comprises a flat plate frame, a handrail is fixedly installed on the side surface of one end of the flat plate frame, and a worm motor is fixedly installed on the side surface of one end of a side vertical support. According to the soil sampling device for water conservancy experiment detection, after a flat plate frame is pushed to a sampling point and fixed, a worm motor can be started to drive a worm gear screw to rotate, so that the worm gear screw can drive a moving platform to move, and the moving platform can vertically move up and down in the direction of a sliding guide rail group; the drill bit motor module can move up and down along with vertical movement of the moving platform, a drill rod can drill into soil along with starting of the drill bit motor module, and the drill bit motor module can stably descend without applying force to the soil sampling device by workers through self-locking performance of a worm gear screw and a sliding guide rail group. And the efficiency and convenience during soil sampling are improved.

This utility model relates to the field of stratified sampling in hydrogeological exploration, and discloses a stratified water-stopping device for geological exploration, including a pipe body, a partition, a shallow water layer suction pipe, a first filter head, a confined water layer suction pipe, a second filter head, a first drain pipe, a second drain pipe, a limiting mechanism, and a water inlet mechanism. The partition is fixed inside the pipe body, and two partitions are provided. The shallow water layer suction pipe, the confined water layer suction pipe, and the first drain pipe all seal through the pipe body. This stratified water-stopping device for geological exploration effectively prevents water from entering the pipe body during descent using an arc-shaped plate, ensuring that water from different layers does not mix. In addition, an electric cylinder is used to fix the pipe body in exploration wells with different inner diameters, which is highly applicable and facilitates the storage of pulleys, making the descent of the pipe body smoother.

The invention discloses an electrolytic hydrogen production system which comprises a hydrogen production module, a total electrolyte tank, a first electrolyte tank and a second electrolyte tank, the hydrogen production module comprises a front end plate and a rear end plate, a plurality of anode plate assemblies and cathode plate assemblies are arranged between the front end plate and the rear end plate at intervals, and meanwhile, the total electrolyte tank is connected with the first electrolyte tank and the second electrolyte tank. A diaphragm piece is arranged between each adjacent anode plate assembly and cathode plate assembly, and the front end plate, the rear end plate, all the anode plate assemblies, all the cathode plate assemblies and all the diaphragm pieces press against one another and are fixedly connected through a plurality of bolts; the electrolyte at the position of the anode plate and the electrolyte at the position of the cathode plate can circularly flow, and the two electrolytes cannot be mixed, so that oxygen and hydrogen in the two electrolytes cannot be mixed, the exhaust purity of the hydrogen and the oxygen is high, the manufacturing is simple, the cost is low, and the application range is wide. A plurality of anode plates and cathode plates are arranged at intervals, so that rapid reaction is realized.
