Description
Technical Field
[0001] This utility model relates to the field of temperature sensor technology, specifically a temperature sensor for water temperature detection. Background Technology
[0002] A temperature sensor is a sensor that can sense temperature and convert 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 broadly classified into two categories based on the measurement method: contact and non-contact. Based on the sensor materials and electronic component characteristics, they are further divided into resistance temperature detectors (RTDs) and thermocouples.
[0003] Existing temperature sensors for measuring water temperature often extend directly underwater and come into direct contact with the water body to measure temperature. The surface of the temperature sensor is prone to accumulating dirt and grime from the water, which affects the measurement accuracy and lifespan of the temperature sensor.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a temperature sensor for water temperature detection, in order to achieve a more practical purpose. Utility Model Content

The output end of the servo motor is fixedly connected to the worm gear, and the other end of the worm gear is rotatably connected to the fixed block. The worm gear cooperates with the worm wheel, which is located directly above the inlet and outlet. The inner ring of the worm wheel is fixed. The cleaning cylinder is fixed, and the bearing is located directly above the worm gear. The bearing is fixed and suspended in the working chamber by the second connecting rod. The second connecting rod is fixedly connected to the outer ring of the bearing. The worm gear is fixedly connected to the inner ring of the bearing by the vertical first connecting rod. The water supply mechanism includes a water tank, a feeding port, a switch, a drain pipe, and a spray ring. The water tank is fixed to one side of the top of the support frame. The feeding port is opened on the outer side of the water tank. The water tank contains cleaning water. The bottom of the water tank is connected to the drain pipe, which extends into the working chamber. The middle of the drain pipe is provided with the switch that extends out of the working chamber. The end of the drain pipe is connected to the hollow ring located directly above the bearing. The hollow ring is fixed to the top wall of the working chamber by a connecting rod.
[0006] Furthermore, the cylinder is fixed in the placement cavity by the support frame, and the cylinder output end extends downward into the working cavity and is fixedly connected to a columnar temperature sensor.
[0007] Furthermore, the inner diameter of the hollow ring, the inner diameter of the bearing, the inner diameter of the cleaning cylinder, and the inlet / outlet diameter are all larger than the diameter of the temperature sensor.
[0008] The beneficial effect of adopting the above-mentioned further solution is that the temperature sensor can be driven to move by the cylinder, so that the temperature sensor passes through the cleaning cylinder, bearing, and hollow ring.
[0009] Furthermore, the inner ring diameter of the bearing is the same as the diameter of the worm gear, and the first connecting rod is evenly distributed on the top surface of the worm gear.
[0010] The beneficial effect of adopting the above-mentioned further solution is that the inner ring of the bearing is driven to rotate by the rotation of the worm gear, and the evenly distributed No. 1 connecting rods avoid uneven force during rotation and damage.
[0011] Furthermore, the cleaning cylinder is densely packed with the soft brushes.
[0012] Furthermore, when the cylinder output end is fully extended, the temperature sensor is fully extended from the working box; when the cylinder output end is fully retracted, the bottom of the temperature sensor is flush with the bottom of the cleaning cylinder.
[0013] Furthermore, the bottom surface of the hollow ring is provided with fine through holes.
[0014] The beneficial effect of adopting the above-mentioned further solution is that when the temperature sensor passes through the cleaning cylinder, its surface comes into contact with the soft brush, and the water spray from the hollow ring with fine filter holes on the bottom surface can clean the surface of the temperature sensor.
[0015] Furthermore, the front end of the work box is equipped with a display screen and a control panel.
[0016] The beneficial effect of adopting the above-mentioned further solution is that the operation status of each component in the work box can be displayed in real time through the display screen, and a control panel is provided to facilitate the control and use of each component.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: By using a cylinder to drive the temperature sensor through the cleaning chamber, when the temperature sensor passes through the cleaning chamber, the cleaning mechanism operates, the servo motor drives the worm gear to rotate, thereby causing the worm wheel, which is fixedly connected to the inner ring of the bearing, to drive the cleaning cylinder to rotate. At this time, the soft brush inside the cleaning cylinder makes full contact with the surface of the temperature sensor, and the water supply mechanism supplies water to the hollow ring to spray water onto the inner wall of the cleaning cylinder. Finally, the surface of the temperature sensor is deeply cleaned, removing dirt, improving the measurement accuracy of the temperature sensor and extending its service life.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1 - Figure 5This utility model provides a technical solution: the water conveying mechanism 400 includes a water tank 4001, a feeding port 4002, a switch 4003, a drain pipe 4004, and a spray ring 4005.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1 - Figure 5This utility model provides a technical solution: Cylinder 300 is fixed in placement cavity 1001 by support frame 1003. The output end of cylinder 300 extends downward into working cavity 1002 and is fixedly connected to columnar temperature sensor 3001. The inner diameter of hollow ring 4005, the inner diameter of bearing 2007, the inner diameter of cleaning cylinder 2006, and the diameter of inlet / outlet 1004 are all larger than the diameter of temperature sensor 3001. When the output end of cylinder 300 is fully extended, temperature sensor 3001 is fully extended out of working box 100 and inserted into the water below working box 100 to measure temperature. When the output end of cylinder 300 is fully retracted, the bottom of temperature sensor 3001 is just flush with the bottom of cleaning cylinder 2006. Cylinder 300 can drive temperature sensor 3001 to move up and down, so that temperature sensor 3001 passes through cleaning cylinder 2006, bearing 2007, and hollow ring 4005 to clean temperature sensor 3001. Specifically, the working principle and usage of this type of water temperature sensor are as follows: Before use, check that all components of the device are intact. Normally, the output end of cylinder 300 is fully extended, and the temperature sensor 3001 is fully extended from the working chamber 100 and enters the water to measure the temperature. When cleaning of the temperature sensor 3001 is required, start the servo motor 2001 through the control panel 600 to slowly retract the output end of cylinder 300. The servo motor 2001 drives the worm gear 2002 to rotate, thereby causing the worm wheel 2003, which is fixedly connected to the inner ring of the bearing 2007, to drive the cleaning cylinder 20. When the temperature sensor 3001 slowly passes through the cleaning cylinder 2006, the soft brush 2009 inside the cleaning cylinder 2006 makes full contact with the surface of the temperature sensor 3001. By turning on the switch 4003, the water tank 4001 containing cleaning water supplies water to the hollow ring 4005 through the drain pipe 4004, thereby spraying water onto the inner wall of the cleaning cylinder 2006. This achieves deep cleaning of the surface of the temperature sensor 3001, removing dirt, thereby improving the measurement accuracy of the temperature sensor 3001 and extending its service life. This structure is simple, easy to use, and has high practical value.
