Description

Technical Field

[0001] This utility model relates to the technical field of automatic detection and early warning equipment, and in particular to an automatic detection and early warning device for septic tanks. Background Technology

[0002] In traditional septic tank management, manual inspection of the liquid level and gas concentration is usually required. However, since septic tanks are often located underground or in concealed areas, manual inspection is not only inconvenient but also cannot achieve continuous, real-time monitoring. This makes it easy to fail to detect abnormal liquid levels or excessive levels of harmful gases in time, which can lead to safety accidents such as sewage overflows and poisoning incidents, seriously affecting the living environment of residents and the personal safety of maintenance personnel.

[0003] While some devices exist for septic tank testing, most are single-function, capable of detecting only one parameter, such as liquid level or gas concentration. They also require external power or data transmission, resulting in high installation and maintenance costs, making them unsuitable for widespread application in ordinary residences or small buildings. Furthermore, some devices have limited alarm mechanisms, relying solely on on-site audible and visual alerts and failing to provide remote information push notifications, hindering timely responses from management personnel.

[0004] Therefore, there is an urgent need for a septic tank detection device that is compact in structure, highly integrated in function, can operate independently, and has wireless communication capabilities, so as to realize automatic monitoring and real-time early warning of key parameters of septic tanks, and improve management efficiency and operational safety.

[0005] In view of this, the inventor has designed a smart monitoring system for septic tanks based on sensor data, which leads to this invention. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0032] like Figures 1 to 3As shown, an automatic detection and early warning device for septic tanks includes a housing 1, a sensor detection component 2, a circuit control board 3, a signal transmission unit 4, an early warning unit 5, and a power supply component 6. The device has a compact overall structure, suitable for integrated installation on the top of a septic tank or at the manhole cover of a building. It features automatic detection, remote early warning, audible and visual alerts, and independent power supply, facilitating future maintenance and large-scale deployment.

[0033] like Figure 1 and Figure 3 As shown, the housing 1 is a hollow structure, injection molded from ABS flame-retardant plastic material, possessing excellent corrosion resistance and sealing performance. The lower end of the housing 1 is equipped with a mounting flange 7, which is fixed to the septic tank cover or pre-drilled mounting holes using expansion bolts, ensuring a secure installation. The interior of the housing 1 forms a component mounting cavity 11, facilitating the layout and connection of various modules; a light-transmitting hole is reserved at the top for solar panel illumination, and an optional protective cover 8 can be installed to prevent rainwater and foreign objects from entering.

[0034] like Figure 2 As shown, the sensing and detection assembly 2 is installed in the lower part of the housing 1 structure, and includes a liquid level sensor 21 and a gas sensor 22. The liquid level sensor 21 is preferably an ultrasonic sensor, with its probe facing the measuring port at the bottom of the housing 1. It is used for non-contact detection of changes in the sewage level inside the septic tank, and has advantages such as being less prone to contamination and having high ranging accuracy. The gas sensor 22 includes a hydrogen sulfide sensor and a methane sensor, respectively arranged near the vent at the bottom of the housing 1. Through reasonable distribution, it can achieve simultaneous sampling of the concentrations of multiple harmful gases, improving the comprehensiveness and reliability of the system's early warning system.

[0035] like Figure 3 and Figure 4 As shown, the circuit control board 3 is located in the middle of the housing 1 and is fixed by the bracket 9. It includes a signal acquisition module, a signal conversion module, and a data analysis module, which are electrically connected in sequence to form a complete signal processing link. When the liquid level or gas sensor 22 acquires data, the signal is converted by A / D and sent to the analysis module. The module determines whether the warning condition has been met based on the preset threshold and generates a data packet for subsequent transmission.

[0036] The signal transmitting unit 4 is mounted on the circuit control board 3, preferably an NB-IoT wireless communication module, but LoRa, GPRS, or other communication protocols can also be selected depending on the actual usage area. The module is connected to the circuit control board 3 via an FPC flexible cable, enabling low-power, long-distance data upload, suitable for outdoor and underground environments with poor communication.

[0037] The early warning unit 5 is located on the top outer edge of the housing 1 and mainly includes a ring of LED light strips 51 and an integrated buzzer 52. When the equipment detects that the liquid level exceeds the limit or the gas concentration is abnormal, the LED light strip 51 flashes and the buzzer 52 sounds, promptly alerting surrounding personnel and ensuring on-site operational safety. At the same time, the early warning information is pushed to the remote monitoring terminal through the communication module, realizing a dual early warning mechanism.

[0038] like Figure 3 As shown, the power supply component 6 includes a solar panel 61 and a battery 62. The solar panel is mounted on the top of the housing 1 via a tilt bracket 9, and its angle can be adjusted according to sunlight conditions to improve charging efficiency. Its output is connected to the power management module, which in turn connects to the internal battery 62, ensuring long-term operation of the device without an external power source. The power management module has overcharge, over-discharge, and short-circuit protection functions to ensure safe and stable system operation.

[0039] Furthermore, to enhance practicality and expandability, without affecting the sealing performance of housing 1, a transparent window area or an openable inspection cover can be provided on housing 1 to facilitate debugging and maintenance; at the same time, an external interface is reserved on the PCB circuit board to expand temperature and humidity sensors, ammonia sensors, etc., to meet different usage needs.

[0040] In summary, this utility model solves the problems of traditional septic tank detection equipment, such as single detection parameters, limited early warning methods, inability to transmit remotely, and reliance on external power supply, by highly integrating multiple functions into a compact device. It has the advantages of comprehensive detection, timely response, flexible use, and simple installation, and is suitable for intelligent management of sewage treatment facilities in various places such as residential areas, public facilities, hospitals, and schools.

[0041] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
