Embodiment Construction

[0013] It can be seen from the embodiments of the present invention shown in the accompanying drawings that there is a water inlet 3 at the bottom of the lower casing, and a float 4 is arranged above the inner water inlet of the lower casing. The lower part of the body is provided with a temperature sensor 8 and a reed switch 9, the reed switch is parallel to the temperature sensor and the lower end is flush with the lower end of the temperature sensor, the reed switch and the temperature sensor are connected in series with the two wires of the double-core sheathed wire 10 Connected, and then filled with waterproof sealing material to fix the temperature sensor, reed switch and double-core sheathed wire in the upper case, and make the temperature sensor and reed switch protrude from the upper case into the lower case and not be connected with it. The inner wall of the lower casing is in contact, and its protruding part is lower than the exhaust hole 6. The upper and lower casin...

Abstract

The invention discloses a portable water level and water temperature measurement instrument, which comprises a lower casing (1) and an upper casing (2), wherein the bottom of the lower casing (1) is provided with a water inlet (3), a floater (4) is arranged inside the lower casing (1), the top of the floater (4) is embedded with a permanent magnet (5), the upper part of a cavity of the floater (4) is provided with exhaust holes (6), the lower casing (1) and the upper casing (2) are connected through screw threads (7), the lower part of the upper casing (2) is provided with a temperature sensor (8) and a reed pipe (9), the temperature sensor and the reed pipe are connected in series in a circuit, a circuit assembly (14) comprises a microcomputer controller (15), a luminescent tube (16), a buzzer (17) and a liquid crystal display (18), when the floater (4) meets water and upwards floats, the reed pipe (9) is controlled by a magnetic field of the magnet (5), the circuit is started, sound and light prompt is given out, meter ruler scale values on a cable (10) are read, and the water level value and the temperature value on the liquid crystal display are obtained.

Description

Technical field [0001] The invention relates to a water level and water temperature measuring instrument, in particular to a portable water level and water temperature measuring instrument suitable for earthquake prediction and water resource management departments to measure the water level and water temperature of observation wells. Background technique [0002] Earthquakes and other geological disasters bring huge disasters to people. Although there is no reliable earthquake prediction method, some useful data related to earthquakes can still be obtained by observing the subtle changes of groundwater level and water temperature. Therefore, earthquake forecasters should A simple-to-use and portable water level and water temperature measuring instrument is provided. [0003] Chinese patent specification 87214793.2 discloses a groundwater level water temperature test recorder. This water level and water temperature test recorder is sealed in a cylindrical shell, and the she...
