[0002] Water monitoring equipment typically requires multiple sensors, such as those for temperature, pressure, pH, conductivity, or dissolved oxygen, to acquire various parameters of the water body. Due to differences in electrical interfaces, communication methods, and installation methods among different sensors, existing devices generally lack uniformity in sensor access and management. This often necessitates separate circuit adaptations and wiring for different sensors, hindering rapid sensor replacement and expansion. Utility Model Content

[0003] This utility model provides a water body detector to solve the defect in the prior art that the water body detector cannot quickly replace or expand the sensors according to the needs due to the differences in electrical interfaces and communication methods of different sensors. By connecting the communication interface of the sensor and the transceiver circuit connected to the main control board to the same bus structure, the water body detector can arbitrarily select the sensor according to the needs.

[0004] This utility model provides a water quality detector, comprising: a main body having multiple fixing holes, each fixing hole defining a female port; a main control board; multiple transceiver circuits connected to the main control board and respectively connected to pins of each female port; multiple sensors, each equipped with an electronic tag, wherein a first end of each sensor is provided with a sensing probe suitable for insertion into the water to obtain measurement parameters, and a second end of each sensor is configured as a male connector suitable for insertion into the female port; the sensor is provided with a communication interface connected to the male connector, and the sensing probe is electrically connected to the communication interface via a signal processing circuit inside the sensor; wherein the communication interface and the transceiver circuits are respectively connected to the same bus structure.

[0005] According to the present invention, a water body detector further includes a protective cover configured to be assembled onto the main body. The protective cover includes: a cover body, including a bottom surface and a side wall extending normally along the bottom surface, wherein the side wall forms an opening at an end away from the bottom surface for allowing the sensor to enter the protective cover, and the side wall is also provided with a plurality of openings; and a plurality of barrier nets correspondingly disposed on each of the openings.

[0006] According to the water body detector provided by this utility model, the opening is a rounded rectangular hole, which is evenly arranged on the side wall.

[0007] According to the present invention, a water body detector is provided in which the openings are arranged at intervals along the axial direction of the protective cover.

[0008] According to the water body detector provided by this utility model, the length of the rounded rectangular hole is 40 mm and the width of the rounded rectangular hole is 16 mm.

[0009] According to the water body detector provided by this utility model, the main body has a threaded part on the side with the fixing hole, and the side wall has a thread at the end near the opening.

[0010] According to the present invention, a water body detector is provided, wherein the bus structure is an RS485 bus.

[0011] According to the water body detector provided by this utility model, the side wall of the fixing hole is provided with a thread, and the side wall of the second end of the sensor is provided with a thread corresponding to the thread of the fixing hole.

[0012] According to the water body detector provided by this utility model, a sealing ring is provided on the sensor and a sealing gasket is provided in the fixing hole.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In related technologies, due to the variety of water quality monitoring instruments and sensors, and the lack of unified management of their interface forms, when water quality monitoring instruments need to connect to different sensors, it is often difficult to quickly replace and expand the sensors due to differences in interface specifications and standards.

[0021] In view of this, the present invention provides a water body detector.

[0023] like Figures 1-4 As shown, the water quality monitoring instrument includes a main body 10 and multiple sensors 20. The main body 10 has multiple fixing holes, each defining a female port 11. The main body 10 includes a main control board and multiple transceiver circuits, which are connected to the main control board and respectively connected to the pins of each female port 11. Each of the multiple sensors 20 is equipped with an electronic tag. The first end of each sensor 20 has a sensing probe, suitable for insertion into the water to obtain measurement parameters. The second end of each sensor 20 is configured as a male connector 21 suitable for insertion into the female port 11. Each sensor 20 has a communication interface connected to the male connector 21. The sensing probe is electrically connected to the communication interface via an internal signal processing circuit. The communication interface and the transceiver circuits are connected to the same bus structure.

[0024] According to an embodiment of the present invention, the main control board can be a circuit board disposed inside the main body, on which a microcontroller and an interface circuit are configured. The microcontroller is electrically connected to multiple transceiver circuits through the interface circuits, and the transceiver circuits complete communication with each sensor, and the microcontroller completes the acquisition and processing of data from each sensor.

[0025] According to embodiments of this utility model, the microcontroller can be a single-chip microcomputer such as STM32, MSP430, PIC, or AVR, or it can be an ARM processor.

[0026] According to an embodiment of the present invention, the sensor 20 can be a conductivity, pH, ORP, dissolved oxygen, ammonia nitrogen, nitrate nitrogen, etc., and can be inserted into the body 10 according to the needs of water body detection.

[0027] According to an embodiment of the present invention, a socket 12 is constructed in the female port 11, and the socket 12 is connected to the pin of the female port 11. When the sensor 20 is inserted into the body 10, the pin 22 of the male head is inserted into the corresponding socket 12 of the female port, thereby connecting the pin 22 with the pin of the female port, thus completing the electrical connection between the sensor 20 and the body 10.

[0028] According to an embodiment of this utility model, the electronic tag of each sensor includes the sensor model, serial number, calibration parameters, factory information, etc. The relevant devices in the main control board can periodically read the electronic tag of the sensor to accurately identify the type of sensor currently inserted on the body, thereby improving the convenience of detection. It should be noted that the electronic tags involved in the sensor all adopt existing technology and are not technologies developed by the applicant.

[0029] According to embodiments of this utility model, data communication between the main control board and each sensor can be based on protocols such as Modbus, Profibus-DP, and DL / T645. For example, multiple sensors can be addressed and polled by the microcontroller on the main control board, enabling the main control board to automatically identify the electronic tags of each sensor and read the corresponding detection data, thereby improving the system's compatibility and scalability.

[0030] It should be noted that the above communication protocols are all general technical protocols or common commercial protocols, and are all prior art. They are not protocols developed by the applicant, nor do they constitute the technical solution of this utility model. They are only used as an example for illustration.

[0031] The water body detector provided by this utility model unifies the physical specifications of the male connector 21 of the sensor 20 and the female connector 11 of the main body 10, ensuring that the male connector 21 can be inserted into the female connector 11. In terms of circuit connection, the transceiver circuit and communication interface are connected under the same bus structure, which also ensures that communication between the sensor 20 and the main control board can be realized. Since the connection between the main body 10 and the sensor 20 is unified at both the physical and electrical levels, the water body detector can arbitrarily select the corresponding sensor 20 according to the needs. Furthermore, since multiple sensors 20 can be inserted on the main body 10, multiple water indicators can be acquired at once, improving the efficiency of water body detection.

[0032] In one illustrative embodiment, the water detector further includes a protective cover 30 configured to be mounted onto the body 10. The protective cover 30 includes a cover body and a plurality of barrier nets. The cover body includes a bottom surface and sidewalls extending normally along the bottom surface, the sidewalls having an opening at an end remote from the bottom surface for allowing the sensor 20 to enter the protective cover 30, and a plurality of openings 31 are also provided on the sidewalls. Furthermore, a plurality of barrier nets are correspondingly disposed on each opening 31.

[0033] According to an embodiment of the present invention, when it is necessary to assemble the protective cover 30, the opening of the protective cover 30 is aligned with the body 10, so that each sensor 20 enters the protective cover 30 through the opening, and then the protective cover 30 is assembled onto the body 10.

[0034] According to the embodiments of this utility model, since there are often many debris such as branches, stones or mud in water bodies, when the sensor 20 is inserted into the water body, due to the action of water flow or the movement of the user, the sensor 20 will often rub against the debris in the water body. This may affect the accuracy of the sensor 20, or even more seriously, damage the sensor 20. By setting a protective cover 30, the sensor 20 can be prevented from directly contacting the debris in the water body, and the barrier net ensures that water flows through the protective cover 30 to ensure the normal operation of the water body detection work.

[0035] In one illustrative embodiment, the opening 31 is a rounded rectangular hole, evenly distributed on the sidewall.

[0036] According to the embodiments of this utility model, since the openings 31 are evenly arranged on the side wall, water flows through in all directions, ensuring the accuracy of the test results. In addition, the rounded corner design can also reduce the occurrence of turbulence in the water flowing into the protective cover 30.

[0037] In one illustrative embodiment, the openings 31 are arranged at axial intervals along the protective cover 30.

[0038] According to the embodiments of this utility model, since the openings 31 are arranged at intervals along the axial direction of the protective cover 30, the sensor 20 can contact water at different depths during the process of the sensor 20 being inserted into the water, which further improves the accuracy of the detection results.

[0039] In one illustrative embodiment, the rounded rectangular hole has a length of 40 mm and a width of 16 mm.

[0040] In one illustrative embodiment, the body 10 has a threaded portion on the side with the fixing hole, and the sidewall has a thread at the end near the opening. The protective cover 30 is assembled onto the body 10 through the threaded engagement between the sidewall and the threaded portion.

[0041] According to an embodiment of the present invention, since the protective cover 30 is threadedly connected to the body 10, when the sensor 20 needs to be replaced, the protective cover 30 can be quickly unscrewed to replace the sensor 20.

[0042] In one illustrative embodiment, the bus structure is an RS485 bus.

[0043] According to the embodiments of this utility model, since the RS485 bus uses differential signal transmission, it has strong anti-interference ability and can ensure signal transmission during the water body detection process.

[0044] In one illustrative embodiment, the sidewall of the fixing hole is provided with threads, and the sidewall of the second end of the sensor 20 is provided with threads corresponding to the threads of the fixing hole.

[0045] In one illustrative embodiment, a sealing ring 23 is provided on the sensor 20, and a sealing gasket 13 is provided in the fixing hole. When the female connector 11 and the male connector 21 are inserted, the sealing ring 23 and the sealing gasket 13 cooperate with each other to seal the joint between the pin of the female connector 11 and the pin of the male connector 21.

[0046] According to an embodiment of the present invention, when the sensor is screwed into the fixing hole, the sealing ring 23 and the sealing gasket 13 are squeezed against each other during the screwing process until the connection between the pin of the female connector 11 and the pin of the male connector 21 is completely sealed.

[0047] In one illustrative embodiment, the water body detector also includes a signal transmission module connected to the main control board.

[0048] According to embodiments of this utility model, the signal transmission module can be a wired transmission module, such as an RS485 module, an RS232 module, or an Ethernet module, thereby facilitating data interaction with a host computer, PLC, or industrial control system.

[0049] According to embodiments of this utility model, the signal transmission module can also be a wireless transmission module, such as a Wi-Fi module, a LoRa module, an NB-IoT module, or a 4G / 5G communication module, so as to directly upload data to a cloud platform or a remote server in remote monitoring scenarios.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
