Problems solved by technology

[0003] The use of the measuring probe in the disposable seawater measuring device is disposable. Therefore, unlike the fixed temperature, salinity and depth measuring equipment, which can be disassembled and replaced frequently, the disposable measuring probe cannot be disassembled after assembly, and can only be used in the cabin. Powered by a set of batteries
After the measuring probe is assembled and sealed, it is easy for the circuit board in the probe to consume the battery power in advance, causing the measuring probe to be scrapped due to its power exhaustion before it is put into the water

Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the disposable seawater measuring device of this embodiment includes two parts: a measuring probe 100 and a transmitting device 200 . Wherein, the measuring probe 100 mainly includes a probe launching tube 110 , a discarding probe 120 and a fixed spool 160 . The discarded probe 120 is installed in the probe launch tube 110, and is used to put into the sea area to be measured to detect the profile data of seawater parameters; the fixed spool 160 is at least partially installed in the probe launch tube 110, and The data wire 140 (for example, an insulated wire such as an enameled wire) is connected to the discarding probe 120 . The data wire 140 is wound on the shaft body of the fixed bobbin 160 and is electrically connected to the metal contact piece 150 arranged on the top surface of the fixed bobbin 160 . ...

Abstract

The invention discloses an expendable seawater measurement device which comprises a measuring probe and a launcher, wherein the launcher comprises a fixing plate, a supporting plate, a spindle, a pull rod and a junction box; a handle, a rolling bearing and an eccentric wheel are mounted on the spindle; the rolling bearing is contacted with the supporting plate; one end of the pull rod is mounted on the fixing plate, and the other end of the pull rod penetrates through a pull rod guide slot of the supporting plate and is connected with an eccentric shaft of the eccentric wheel; the junction box is positioned between the fixing plate and the supporting plate; a contact pin used for being contacted with a metal contact on the measuring probe is arranged on a side face, which faces the fixing plate, of the junction box; a tightening spring is arranged on a side face, which faces the supporting plate, of the junction box; and the junction box is connected with the supporting plate through the tightening spring. According to the expendable seawater measurement device disclosed by the invention, the acquired data can be effectively transmitted in real time when the measuring probe is reliably put in, and the expendable seawater measurement device is simple in structure, light and reliable and is conveniently operated and used on deck by scientific research personnel.

Description

technical field [0001] The invention belongs to the technical field of seawater measuring devices, and in particular relates to a throw-away measuring device for detecting seawater parameters. Background technique [0002] Temperature and salinity are the most important parameters of seawater. The disposable seawater measuring device used to measure the temperature and salinity of seawater at different depths uses the disposable probe to measure the seawater temperature and salinity during the process of free fall in seawater. profile data. This throw-away seawater measuring device generally consists of a measuring probe and a launcher, and each set of launcher can launch several measuring probes in turn. The temperature, salinity, pressure sensor, data acquisition circuit and power supply battery are integrated in the measuring probe, and the transmitting device is connected to the measuring probe through a wire, and transmits the seawater parameter data collected by the m...
