Description

Technical Field

[0001] This utility model belongs to the field of waterway engineering measurement technology, specifically a measuring device for online measurement of water salinity and temperature. Background Technology

[0002] Currently, the commonly used methods for water depth measurement are single-beam and multi-beam measurement. Their working principle is based on acoustic sensing technology, determining water depth by sending sound waves and measuring their propagation time and reflection intensity. However, factors such as water temperature and salinity affect the speed of sound, thus impacting the depth measurement accuracy of the depth sounder. Currently, only individual temperature or salinity measurement devices are available on the market; there are no integrated online measurement devices for both temperature and salinity. Therefore, when water depth measurement is required, a thermometer is typically used to measure temperature first, followed by a salinity meter. This measurement process is relatively cumbersome, and deviations at the measurement points may lead to discrepancies between temperature and salinity data, affecting the accuracy and effectiveness of subsequent water depth measurements.

[0039] See Figure 1-7 An online water salinity and temperature measurement device includes an instrument control cabinet 1, which is fixed to the top of a cable cabinet 2. The cable cabinet 2 is equipped with a first salinity sensor connection fitting 4, a second salinity sensor connection fitting 7, and a temperature sensor connection fitting 3. A first salinity sensor assembly 6 for measuring water salinity is installed at the end of the first salinity sensor connection fitting 4, and a second salinity sensor assembly 8 for measuring water salinity is installed at the end of the second salinity sensor connection fitting 7. The first salinity sensor assembly 6 and the second salinity sensor assembly 8 are connected to the instrument control cabinet 1 via the cable cabinet 2. A temperature sensor assembly 5 for measuring water temperature is installed at the end of the temperature sensor connection fitting 3, and the temperature sensor assembly 5 is connected to the instrument control cabinet 1 via the cable cabinet 2. This measurement device can simultaneously measure the salinity and temperature of the water body at the current time, thereby providing error correction for the depth sounder's measurement of water depth. Furthermore, this device is portable, adaptable to various measurement environments, and can significantly reduce the workload of measurement personnel. In actual use, the measuring personnel use a handheld measuring device to insert the first salinity sensor connecting pipe 4 and the second salinity sensor connecting pipe 7 into the water at a certain depth to measure the salinity of the water. At the same time, the temperature is measured through the temperature sensor assembly 5, and finally the salinity and temperature data are transmitted synchronously to the instrument control cabinet 1 through the signal line.

[0040] Furthermore, the instrument control cabinet 1 includes an instrument cabinet 102, and a display instrument 101 for displaying measurement results is provided at the top of the instrument cabinet 102. The instrument cabinet 102 facilitates the collection of data and its display via the display instrument 101, thereby improving measurement efficiency.

[0041] Furthermore, a first mounting hole 201 for installing the first salinity sensor connecting pipe 4 is machined on the outer front wall of the cable cabinet 2. The first mounting hole 201 enables reliable installation of the first salinity sensor connecting pipe 4 and facilitates the passage of the signal line.

[0043] The side of the second mounting hole 202 is also machined with a third mounting hole 203 for mounting the second salinity sensor connecting pipe 7. The third mounting hole 203 enables reliable installation of the second salinity sensor connecting pipe 7 and facilitates the passage of the signal line.

[0044] Furthermore, the first salinity sensor connecting pipe 4 and the second salinity sensor connecting pipe 7 adopt the same structure and are symmetrically arranged with the temperature sensor connecting pipe 3. This symmetrical arrangement ensures measurement accuracy.

[0045] Furthermore, the first salinity sensor connecting pipe 4 includes a first horizontal pipe 402, which is fixedly connected to the cable cabinet 2 by a first locking nut 401.

The measuring cable collects the measurement signal and transmits it to the instrument control cabinet. The salinity sensor should be placed below the water surface.

[0047] Furthermore, the temperature sensor connecting pipe 3 includes a second horizontal pipe 302, which is fixed to the cable cabinet 2 by a fourth locking nut 301.

[0048] Furthermore, the temperature sensor assembly 5 includes a temperature sensor 502, which is fixedly connected to the conical sealing plate 304 via a third locking nut 501. The temperature sensor assembly 5 facilitates subsequent temperature measurement.

[0049] Furthermore, the temperature sensor 502 is an infrared temperature sensor placed above the water surface. Through infrared temperature measurement, the infrared radiation energy is measured and converted into an electrical signal, which is then converted into a temperature signal according to the fundamental law of radiation and transmitted to the instrument control cabinet.
