Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a temperature sensor for monitoring liquid temperature. Background Art

[0002] A temperature sensor is a sensor that senses temperature and converts it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in a wide variety. They can be categorized by measurement method: contact and non-contact. Based on the sensor material and electronic component characteristics, they can be divided into thermal resistors and thermocouples. Temperature sensors are also one of the most common devices in our daily lives, capable of detecting temperature and making our lives more convenient.

[0003] The existing device has the following shortcomings when in use: the temperature sensor for monitoring the liquid can only monitor the temperature of the liquid at a fixed depth because the position of the temperature sensing head is fixed. The height of the temperature sensing head cannot be adjusted as needed to monitor the temperature of the liquid at different depths, making the temperature sensor not very practical. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a temperature sensor for monitoring liquid temperature, which solves the technical problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a temperature sensor for liquid temperature monitoring, including a sensor signal processor, one side of the sensor signal processor is connected to a wiring terminal, a mounting base is fixedly installed on the bottom wall of the sensor signal processor, a telescopic rod is fixedly installed on the bottom wall of the mounting base, a probe is fixedly installed on the telescopic end of the telescopic rod, an outer tube is provided outside the telescopic rod, the top end of the outer tube is movably installed in the mounting base, the inner thread of the outer tube is connected to the inner tube, the bottom end of the inner tube is fixedly installed on the probe, a motor is fixedly installed in the mounting base, and the driving end of the motor is connected to a driving gear.

[0006] Preferably, the inner wall surface of the outer cylinder is engraved with threads, and the outer wall surface of the inner cylinder is engraved with thread grooves engaged with the threads of the outer cylinder, and the outer cylinder and the inner cylinder are threadedly connected.

[0007] Preferably, the outer cylinder is rotatable on the mounting base, and gear teeth meshing with the driving gear are provided on the outer side wall surface of the top end of the outer cylinder, and the driving gear meshes with the outer cylinder.

[0008] Preferably, the telescopic rod adopts a telescopic rod structure with a limiting slot, and the telescopic end of the telescopic rod can only move in the vertical direction and cannot rotate.

[0009] Preferably, the wires connecting the probe and the sensor signal processor are installed inside the telescopic rod.

[0010] Beneficial effects

[0011] The utility model provides a temperature sensor for monitoring liquid temperature, which has the following beneficial effects: when the device is in use, the outer cylinder can be driven by the motor to rotate, and because the inner cylinder and the probe are fixedly connected, and the probe is connected to the mounting base through a non-rotatable telescopic rod, the outer cylinder will drive the inner cylinder and the probe to rise and fall when it rotates, so that the temperature at different depths in the liquid can be measured, thereby improving the functionality and practicality of the device.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-2 The utility model provides a technical solution of a temperature sensor for monitoring liquid temperature: a temperature sensor for monitoring liquid temperature, comprising a sensor signal processor 1, one side of the sensor signal processor 1 is connected to a terminal 2, a mounting base 3 is fixedly mounted on the bottom wall of the sensor signal processor 1, a telescopic rod 7 is fixedly mounted on the bottom wall of the mounting base 3, a probe 9 is fixedly mounted on the telescopic end of the telescopic rod 7, an outer tube 6 is provided outside the telescopic rod 7, the top end of the outer tube 6 is movably mounted in the mounting base 3, the outer tube 6 is threadedly connected to an inner tube 8, the bottom end of the inner tube 8 is fixedly mounted on the probe 9, a motor 4 is fixedly mounted in the mounting base 3, and the driving end of the motor 4 is connected to a driving gear 5.

[0017] Furthermore, the inner wall surface of the outer cylinder 6 is engraved with threads, and the outer wall surface of the inner cylinder 8 is engraved with thread grooves that mesh with the threads of the outer cylinder 6. The outer cylinder 6 and the inner cylinder 8 are connected by threads.

[0018] Furthermore, the outer cylinder 6 can rotate on the mounting base 3 , and gear teeth meshing with the driving gear 5 are provided on the outer wall surface of the top end of the outer cylinder 6 , and the driving gear 5 meshes with the outer cylinder 6 .

[0019] Furthermore, the telescopic rod 7 adopts a telescopic rod structure with a limiting slot, and the telescopic end of the telescopic rod 7 can only move in the vertical direction and cannot rotate.

[0020] Furthermore, the wires connecting the probe 9 and the sensor signal processor 1 are all installed inside the telescopic rod 7 .

[0021] Example: When using this device, first fix the sensor signal processor 1 on the measuring device, insert the probe 9 into the measuring liquid, connect the terminal 2 to the circuit, and form a sensor structure for measuring the temperature of the measuring liquid to measure the temperature of the measuring liquid.

[0022] When the temperature measurement position needs to be adjusted, the motor 4 drives the driving gear 5 to drive the outer cylinder 6 to rotate. Since the probe 9 is fixedly installed with the telescopic rod 7, the probe 9 cannot rotate. The inner cylinder 8 is fixedly installed on the probe 9, so the inner cylinder 8 cannot rotate either. When the outer cylinder 6 rotates, the outer cylinder 6 and the inner cylinder 8 are threadedly connected. The inner cylinder 8 moves in the vertical direction through the cooperation of the threads, so that the probe 9 is raised or lowered, and the temperature of different liquid levels in the liquid is measured.
