The invention discloses a novel automatic water pipe type settlement meter measuring device which comprises an observation screen. Multiple observation pipes are arranged in the observation screen, and a temporary water tank is arranged behind the observation screen and communicated with the observation pipes; pressure sensors are installed under the observation pipes; the observation screen is connected with a water storage barrel assembly, and the water storage barrel assembly comprises a water storage barrel, a liquid level switch, a connecting pipe, a booster pump and a four-way valve, wherein the inner wall of the water storage barrel is provided with the liquid level switch, the bottom of the water storage barrel is provided with the booster pump, one side of the booster pump is connected with water storage barrel, and the other side of the booster pump is connected with the observation screen and an artificial water tank through the four-way valve. According to the novel automatic water pipe type settlement meter measuring device, a novel automatic water pipe type settlement meter is high in precision, accuracy and long-term stability, automatic monitoring on vertical displacement of an earth and rockfill dam is completely achieved, the measuring time and the measuring frequency can be separately set, manpower and material resources are saved, the measuring cost is lowered, the measuring precision is improved, and the device can be widely applied to internal vertical displacement monitoring of the earth and rockfill dam and other similar projects.

The invention relates to a device for sampling parameters of an environment outside an underground shelter in a coal mine and a non-coal mine, which is used for sampling parameters of the environment outside an underground mobile lifesaving cabin or a fixed refuge cave in the coal mine and the non-coal mine. The device comprises an air circulation pipe, a gas sampling structure, a multi-parametersensor structure and a sampled signal outputting device; the air circulation pipe is arranged outside the movable lifesaving cabin or the fixed refuge cave; and a sensor used for sampling is arrangedin the mobile lifesaving cabin or the fixed refuge cave and used for sampling air convected through the air circulation pipe in the mine. The sampling device disclosed by the invention solves the problem that the multi-parameter sensor for measuring the parameters of the environment outside the mobile lifesaving cabin or the fixed refuge cave cannot be used normally because the sensor is easy to be damaged by the impact force and the explosion force from the underground explosion and other disasters in the coal mine and the non-coal mine and can guarantee that the sensor is not destroyed in underground explosion and other disasters, but can still normally measure the environmental parameters.

The invention provides a mandrel support roller height measuring ruler. The measuring ruler includes a measuring ruler beam, which is respectively connected with a measuring ruler column at both ends of the measuring ruler beam to form a U-shaped frame. Measuring base. At the same time, it also provides a method for measuring the height of the mandrel support roller with the measuring ruler. The steps are: ① place the measuring ruler on the rack slide rail; ② control the height of the mandrel by lifting the supporting roller; The distance between them is adjusted to the set value of the height H of the mandrel support roller of this specification. The effect of the invention is that after using the measuring ruler, the accuracy of measuring the height of the mandrel support roller is improved, the mandrel is in normal use, and the steel consumption per ton reaches and exceeds the original design level. The method of measuring from above reduces the disadvantage of scalding the arm, eliminates the possibility that the mandrel support roller suddenly fails and causes serious injury to the measuring person's arm, and improves safety. The measurement method is relatively simple, practical, safe, accurate and fast.

The invention relates to a photoelectric analysis method for gas in a pipeline. The method comprises the following steps that: gas to be detected in the pipeline is introduced into a measurement pipe; an airflow perturbator is arranged in the measurement pipe; a gas guiding hole which penetrates through the airflow perturbator is formed in the airflow perturbator; light which is emitted by a light source passes through the gas to be detected on the downstream of the airflow perturbator in the measurement pipe, is absorbed by the gas to be detected, then is received by a detector and is converted into an electrical signal; and an analysis unit processes the electrical signal output by the detector so as to acquire the concentration of the gas to be detected. The invention also discloses a device for realizing the method.

The invention provides a reference signal transmitting method, a receiving method and a device within a non-authorized frequency band. According to the invention, through increasing the transmitting chance of a DRS signal within the transmitting period of each reference signal, the phenomenon that reference signals cannot be continuously transmitted by an LTE system within the non-authorized frequency band is reduced or avoided. In this way, the transmitting / receiving of reference signals is ensured. Meanwhile, the normal RRM measurement of a terminal is ensured.
