Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and more specifically, to an integrated sensor. Background Technology

[0002] Integrated sensors are sensor systems that integrate multiple sensing functions, signal processing circuits, interface circuits, etc., into the same chip or package. The development of their background technology is closely related to the demand for miniaturization, intelligence, and multifunctionality of sensors.

[0003] There are many existing technologies for integrated sensors, such as:

[0004] Chinese Patent (Application No.: CN201921614847.3) discloses an integrated sensor, including a main housing. An aluminum-cased PTC heating element and a water level sensor are disposed within the main housing. The aluminum-cased PTC heating element and the water level sensor are respectively connected to an external power supply via a PCB board. This invention utilizes a PTC heating element protected by an aluminum casing, making it more adaptable to working in complex environments. The welding of the aluminum-cased PTC heating element to the temperature fuse in this invention employs a PCB board welding connection structure, allowing for one-to-one positioning and welding, preventing mis-soldering and missed soldering, greatly simplifying assembly, reducing the risk of mis-soldering and missed soldering, and improving production efficiency.

[0005] Traditional water quality monitoring equipment often uses a combination of multiple independent sensors (such as separate COD sensors, turbidity sensors, and liquid level sensors), resulting in large equipment size, complex wiring, and potential signal interference or data asynchrony between sensors. Furthermore, in water quality monitoring scenarios, when sensors are immersed in water for extended periods, pollutants (such as algae, silt, and organic matter) easily adhere to their surfaces, leading to decreased measurement accuracy. This necessitates frequent manual cleaning or replacement, resulting in high maintenance costs and impacting the continuity of monitoring. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing an integrated sensor, which solves the problems of large device size, complex wiring, potential signal interference or data asynchrony between sensors, and the lack of integrated motor brush for self-cleaning function in traditional technologies.

[0007] To achieve the above objectives, this utility model provides an integrated sensor, including a main housing. A COD / turbidity measuring body is threadedly connected to the bottom of the main housing. A liquid level PCB chamber is threadedly connected to the bottom of the COD / turbidity measuring body. A fluororubber scraper is installed inside the COD / turbidity measuring body. A second brush fixing device is installed on one side of the fluororubber scraper. A drive shaft is fixedly connected inside the second brush fixing device. The upper end of the drive shaft is fixedly connected to the output end of a reduction motor. The reduction motor drives the drive shaft to rotate the fluororubber scraper inside the COD / turbidity measuring body to achieve a self-cleaning function.

[0008] The beneficial effects of this utility model are:

The fluororubber scraper, the first brush fixing device and the second brush fixing device are fixedly connected by an external connector. The reduction motor is installed inside the main housing, and the drive shaft is rotatably connected to the COD / turbidity measuring body.

[0019] The advantages of adopting the above-mentioned further solutions are that the structure is robust, can adapt to harsh water quality environments, and the external connectors allow for individual replacement when a single component is damaged, thus reducing maintenance costs.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] The main housing, COD / turbidity measurement body, and liquid level PCB chamber are integrated into one unit through threaded connection, integrating COD / turbidity measurement and liquid level monitoring functions into the same device. This reduces the volume and cost of multi-sensor combinations, enables simultaneous measurement of multiple parameters (COD, turbidity, liquid level), simplifies the system structure, makes the product more compact, and is more suitable for narrow environments with diameter requirements.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Please see Figs. 1-2 As shown, this embodiment provides an integrated sensor, including a main housing 1. Considering that traditional technologies involve large device size, complex wiring, potential signal interference or data asynchrony between sensors, and the lack of an integrated motor-driven brush for self-cleaning, requiring frequent manual cleaning or replacement and resulting in high maintenance costs, a COD / turbidity measuring body 2 is threadedly connected to the bottom of the main housing 1. A liquid level PCB chamber 3 is threadedly connected to the bottom of the COD / turbidity measuring body 2. A fluororubber scraper 4 is installed inside the COD / turbidity measuring body 2. A second brush fixing device 42 is installed on one side of the fluororubber scraper 4. A drive shaft 43 is fixedly connected inside the second brush fixing device 42. The upper end of the drive shaft 43 is fixedly connected to the output end of a reduction motor 44. The reduction motor 44 drives the drive shaft 43 to rotate the fluororubber scraper 4 inside the COD / turbidity measuring body 2 to achieve the self-cleaning function.

[0032] In summary, the improvement of this embodiment lies in:

[0033] The main housing 1, COD / turbidity measurement body 2, and liquid level PCB chamber 3 are integrated into one unit through threaded connection, integrating COD / turbidity measurement and liquid level monitoring functions into the same device, reducing the volume and cost of multi-sensor combinations, realizing simultaneous measurement of multiple parameters (COD, turbidity, liquid level), simplifying the system structure, making the product more compact, and more suitable for narrow environments with diameter requirements.

[0034] During use, a rotatable fluororubber scraper 4 is installed inside the COD / turbidity measuring body 2. The fluororubber scraper 4 is rotated by the drive shaft 43 driven by the reduction motor 44, thereby achieving self-cleaning of the sensing elements inside the measuring body. This avoids measurement errors caused by the sensing elements being covered, reduces the frequency of manual maintenance, extends the sensor calibration cycle, and improves the reliability of long-term monitoring data.

[0035] Based on the above, other structures also need to be disclosed in detail, such as:

[0036] In order to achieve synchronous monitoring of multiple parameters, a main control circuit board 11 and a drive board 12 are respectively installed inside the main housing 1. The main control circuit board 11 and the drive board 12 realize the unified acquisition and processing of multi-parameter data, thereby improving data synchronization and system compatibility.

[0037] Considering that the measured values ​​of water quality parameters are easily affected by water temperature, a wire hole 21 and a temperature port 22 are respectively set inside the COD / turbidity measuring body 2. The photoelectric signal cable of the COD measurement module can be connected to the main control circuit board 11 of the main housing 1 through the wire hole 21 to ensure stable signal transmission. A temperature sensor is installed inside the temperature port 22 to monitor the internal temperature of the body in real time. The main control circuit board 11 uses the temperature data to perform algorithm compensation on the COD / turbidity measurement results to eliminate temperature drift error and improve measurement accuracy.

[0038] To enable the sensor to monitor the water level in real time and determine whether the measured values ​​of COD, turbidity, and temperature are within the current values ​​of the water sample, a level sensing element 31 is installed inside the level PCB chamber 3. A level protective cover 32 is threadedly connected to the bottom of the level PCB chamber 3. The level sensing element 31 can detect the water level in real time, providing level data support for the integrated sensor. It is integrated with the COD / turbidity measuring body 2 into the same sensor, realizing synchronous monitoring of water quality parameters and water level parameters, reducing the number of on-site equipment installations. The level protective cover 32 can prevent floating objects in the water from directly contacting the level sensing element 31, avoiding measurement failure caused by the adhesion of debris.

[0039] To improve the stability of the fluororubber scraper 4 during use, a first brush fixing device 41 is provided on the other side of the fluororubber scraper 4. The fluororubber scraper 4, the first brush fixing device 41, and the second brush fixing device 42 are fixedly connected by external connectors. The reduction motor 44 is installed inside the main housing 1, and the drive shaft 43 is rotatably connected to the COD / turbidity measuring body 2. The fluororubber scraper 4, the first brush fixing device 41, and the second brush fixing device 42 are fixed by external connectors such as bolts and buckles, forming a rigid connection structure of "scraper-support-drive shaft". The structure is stable and can adapt to harsh water quality environments. The external connectors allow for individual replacement when a single component is damaged (such as replacing only the worn fluororubber scraper 4), reducing maintenance costs. The drive shaft 43 is rotatably connected to the COD / turbidity measuring body 2 through bearings, and with the help of a sealing ring, it achieves the dual functions of "low resistance rotation + waterproof sealing".

[0040] In summary, the working principle of this solution is as follows:

[0041] The sensor body consists of a main housing 1, a COD / turbidity measurement body 2, and a liquid level PCB compartment 3, all connected by threads. The main housing 1 integrates a main control circuit board 11 and a drive board 12, serving as the system control core responsible for data processing, signal transmission, and device driving. The COD / turbidity measurement body 2 has a wiring hole 21 and a temperature port 22. The former is used to organize internal cables and ensure stable signal transmission, while the latter can accommodate a temperature sensor to provide temperature compensation data for COD and turbidity measurements, improving measurement accuracy. The liquid level monitoring function is implemented by the liquid level PCB compartment 3, whose internal liquid level sensing element 31 detects the water level in real time and uploads the data via the main control circuit board 11. A liquid level protection cover 32, threaded to the bottom of the compartment, can block debris, buffer water flow impact, prevent damage to the sensing element, and facilitate disassembly and maintenance.

[0042] The fluororubber scraper 4 is connected to the drive shaft 43 via the first brush fixing device 41 and the second brush fixing device 42, and the three are fixed by external connectors. The reduction motor 44 is installed inside the main housing 1. After long-term use, its output end drives the drive shaft 43 to rotate, thereby driving the scraper 4 to rotate inside the COD / turbidity measuring body 2. The scraper is in close contact with the measuring window, which can promptly remove attached algae, silt and other pollutants, ensuring the surface of the sensing element is clean and maintaining measurement accuracy. The main control circuit board 11 has a built-in cleaning program. The self-cleaning interval and cleaning frequency can be set through the program. Through the above design, this integrated sensor can not only achieve accurate measurement of multiple parameters such as COD, turbidity and liquid level, but also significantly reduce the maintenance frequency, making it suitable for a variety of complex water quality monitoring scenarios.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
