Description

Technical Field

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

[0002] A sensor is a detection device that senses the information being measured and, according to certain rules, transforms it into an electrical signal or other desired form of information output to meet the requirements of information transmission, processing, storage, display, recording, and control. The existence and development of sensors have given objects senses such as touch, taste, and smell, bringing them to life. Sensors are an extension of the human five senses, characterized by miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. They are the primary link in achieving automatic detection and control. The new aluminum nitride sensor can operate at temperatures as high as 900°C.

[0003] After searching, the existing patent (publication number: CN209992390U) discloses a sediment sensor based on near-infrared light reflection, including a top cover, a connecting shell and a detection shell, the side wall of the detection shell is symmetrically provided with light-transmitting holes, a light-transmitting plate is installed in the light-transmitting hole, and a detection component corresponding to the light-transmitting plate is provided in the detection shell, the detection component includes a frustum cavity with a horizontal axis, the bottom surface of the frustum cavity faces the light-transmitting plate, and its side surfaces are evenly provided with light sources emitting near-infrared light, and its top surface is provided with photoelectric detectors for detecting the intensity of near-infrared light reflected by sediment, the photoelectric detectors are symmetrically arranged at both ends of the positioning seat, and the positioning seat is fixedly connected to the support seat provided at the bottom of the detection shell. The purpose of this utility model is to provide a sediment sensor based on near-infrared light reflection to solve the technical problem that the existing sediment sensor based on near-infrared light reflection has changed the water flow rate before measurement and the photoelectric compensation cannot effectively reduce the measurement error.

[0004] However, in the process of operation, the existing sediment sensor has a very high requirement on the accuracy of the thread because the cylinder and the cover are connected by threads. If the thread is slightly deformed or the processing accuracy is insufficient, the sealing will be poor after installation and it is easy to leak. Since the cylinder is cylindrical, a pipe clamp must be used in conjunction with a clamp to tighten the cylinder and the cover, which is very inconvenient to install and difficult to disassemble and assemble on site. During installation, it is easy to damage the paint on the cylinder or deform the cylinder, and it is easy to damage the signal transmission line. Since the diameter of the cylinder is large, after installation, the total mass of the equipment is large, and the overall size is large, which is inconvenient to carry and the appearance is not refined enough.

[0005] Therefore, a sediment sensor is proposed to address the above problems. Utility Model Content

[0006] (1) Technical problems solved

[0007] In response to the deficiencies in the prior art, the present invention provides a sediment sensor that solves the problem mentioned in the background art that during operation, the existing sediment sensor, as the cylinder and the cover are threadedly connected, requires very high precision of the thread. If the thread is slightly deformed or the processing precision is insufficient, the sealing will be poor after installation and it will be prone to water leakage. Since the cylinder is cylindrical, a pipe clamp must be used in conjunction with a clamp to tighten the cylinder and the cover, which is very inconvenient to install and difficult to disassemble and assemble on site. During installation, the paint on the cylinder may be easily damaged or deformed, and the signal transmission line may be easily damaged. Since the cylinder has a large diameter, after installation, the total mass of the equipment is large, and the overall dimensions are large, making it inconvenient to carry and the appearance is not refined enough.
