Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and more specifically, to a portable multi-parameter water quality analyzer. Background Technology

[0002] Water quality analyzers, also known as water quality testing instruments, are used to analyze the content of various pollutant ions in water bodies. In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge. The decline in drinking water quality poses a great threat to human health. Water quality analyzers play an important role in environmental protection, water quality testing, and water resource protection. Pollutants include: pH, DO, COD, ammonia nitrogen, total phosphorus, total nitrogen, suspended solids, turbidity, pH, lead, copper, arsenic, etc. Water quality analyzers provide water treatment institutions with accurate and rapid pollutant ion content. Multi-parameter water quality analyzers are generally carried by placing them inside a case for easy portability.

[0003] Patent application CN2023227915615 discloses a portable multi-parameter water quality analyzer, including a portable case and a water quality analyzer body. The water quality analyzer body is located inside the portable case. An inflatable airbag is installed on the inner wall of the portable case. A limiting frame is set inside the portable case, and the limiting frame contacts the inner ring of the inflatable airbag. The water quality analyzer body is located inside the limiting frame and contacts the inner wall of the limiting frame. Two locking plates are slidably connected to the top of the limiting frame, and the locking plates contact the top of the water quality analyzer body. This utility model protects the water quality analyzer body by setting an enclosed inflatable airbag inside the portable case. The movable limiting frame can buffer and absorb shocks from collisions in any direction. At the same time, the use of a push plate and a wedge block can complete the movement of the locking plates during the inflation or deflation of the inflatable airbag, thereby achieving automatic limiting and unlocking, reducing the number of steps required for manual operation.

[0004] The device has certain problems during use. For example, the structure is an integrated protective airbag. When it falls and collides, the airbag is under high pressure in all directions, causing the detector to still shake back and forth inside the airbag, resulting in poor protection. In addition, manual inflation is required to ensure the protective effect. Furthermore, portable detectors often need to be placed in the testing environment, and the structure is prone to contamination in muddy or watery environments. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a portable multi-parameter water quality analyzer to solve the problems in the background technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] A portable multi-parameter water quality analyzer includes a protective shell and a multi-parameter analyzer body installed inside it. A lid is hinged to the top of the protective shell. Evenly distributed protective airbags are fixedly installed on the inner wall of the protective shell, and these airbags are in close contact with the multi-parameter analyzer body. An air pump is fixedly installed on the right side of the protective shell. An annular multi-port pipe is fixedly installed on the inner wall of the protective shell, and both the air pump and the protective airbags are connected to the annular multi-port pipe. A solenoid valve is fixedly installed on each of the protective airbags. An accelerometer sensor is fixedly installed inside each of the protective airbags. A processor is fixedly installed on the inner wall of the protective shell. The accelerometer sensor and the solenoid valves are both signal-connected to the processor. The accelerometer sensor acquires the falling angle and velocity values ​​of the protective shell and transmits the signals to the processor. The processor controls the opening and closing of the corresponding solenoid valve based on the acquired velocity values.

[0008] As a further description of the above technical solution: a top airbag is fixedly installed on the inner wall of the box cover, and the bottom of the top airbag is in contact with the main body of the multi-parameter detector.

[0009] As a further description of the above technical solution: a pressure sensor is installed inside the protective airbag. Both the pressure sensor and the air pump are connected to the processor. The pressure sensor is used to acquire the internal pressure value of the protective airbag and transmit it to the processor. The processor controls the air pump to start and stop based on the acquired pressure value compared with a set threshold.

[0010] As a further description of the above technical solution: the inner wall of the protective shell is equipped with evenly distributed buckles, and the annular multi-port tube is located inside the buckles.

[0011] As a further description of the above technical solution: an assembly frame is fixedly installed at the bottom of the protective shell, a lead screw is rotatably connected to the inner wall of the assembly frame, two synchronous seats are threadedly connected to the lead screw, evenly distributed movable seats are rotatably connected to the inner wall of the assembly frame, support legs are connected to the movable seats, limit gears are fixedly installed on the movable seats, and two toothed plates are fixedly installed on the synchronous seats, the toothed plates meshing with the limit gears.

[0012] As a further description of the above technical solution: an adjustment knob is installed on the right side of the assembly frame, and the adjustment knob is connected to the right end of the lead screw.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] This invention provides all-around protection for the multi-parameter detector body through a protective shell, and uses multiple sets of protective airbags to buffer impacts from different directions. These airbags are supplied with air by a single air pump through a ring-shaped multi-port pipe, simplifying the air supply system while maintaining protective performance. In the event of a drop, an acceleration sensor monitors the drop status in real time, and the processor quickly controls the corresponding solenoid valve to selectively release pressure, forming a gradient buffer protection to reduce damage to the multi-parameter detector body, thus achieving intelligent impact protection. The adjustable outrigger mechanism within the assembly frame allows for quick adjustment of the outrigger's deployment angle and height during operation in complex terrain, ensuring stable measurement and improving the equipment's environmental adaptability and measurement accuracy.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0022] Please see Figure 1-4In this utility model, a portable multi-parameter water quality analyzer includes a protective shell 1 and a multi-parameter analyzer body 2 installed inside it. A lid 3 is hinged to the top of the protective shell 1, and a top airbag 8 is fixedly installed on the inner wall of the lid 3, with the bottom of the top airbag 8 fitting snugly against the multi-parameter analyzer body 2. Evenly distributed protective airbags 4 are fixedly installed on the inner wall of the protective shell 1, and the protective airbags 4 fit snugly against the multi-parameter analyzer body 2. An air pump 5 is fixedly installed on the right side of the protective shell 1, and a ring-shaped... The multi-port pipe 6, air pump 5, and protective airbag 4 are all connected to the annular multi-port pipe 6. A solenoid valve 401 is fixedly installed on the protective airbag 4. An acceleration sensor 402 is fixedly installed inside the protective airbag 4. A processor 7 is fixedly installed on the inner wall of the protective shell 1. The acceleration sensor 402 and the solenoid valve 401 are both connected to the processor 7. The acceleration sensor 402 is used to obtain the falling angle and speed value of the protective shell 1 and transmit the signal to the processor 7. The processor 7 controls the opening and closing of the corresponding solenoid valve 401 according to the obtained speed value.

[0023] The protective airbag 4 is equipped with a pressure sensor 403. Both the pressure sensor 403 and the air pump 5 are connected to the processor 7. The pressure sensor 403 is used to obtain the internal pressure value of the protective airbag 4 and transmit it to the processor 7. The processor 7 controls the air pump 5 to open and close based on the obtained pressure value and the set threshold.

[0024] When water quality testing is required, the user first opens the cover 3 of the protective housing 1, takes out the multi-parameter detector body 2 for measurement, and puts the multi-parameter detector body 2 back into the protective housing 1 after the measurement is completed. The cover 3 is then closed. At this time, the processor 7 controls the air pump 5 to start, and gas is injected into the protective airbag 4 through the annular multi-port pipe 6, so that the multi-parameter detector body 2 is completely wrapped by the airbag, forming a buffer protective layer. The air pressure sensor 403 monitors the internal pressure of the airbag in real time and feeds the data back to the processor 7. If the air pressure is lower than the set threshold, the processor 7 will control the air pump 5 to replenish the gas, ensuring that the protective airbag 4 and the top airbag 8 are always in the best protective state.

[0025] If the device is accidentally dropped, the acceleration sensor 402 will detect the falling speed, angle and impact direction of the protective shell 1 in real time and transmit the data to the processor 7. The processor 7 controls the solenoid valve 401 in the corresponding direction to close tightly according to the impact direction, so that the protective airbag 4 in that area maintains high pressure. The solenoid valve 401 in the other protective airbags 4 opens to release some gas, forming a gradient buffer structure, thereby dispersing the impact force and preventing damage to the multi-parameter detector body 2. The protective airbags 4 in other directions maintain a high pressure state to ensure all-round protection.

[0026] After the drop impact, the processor 7 restarts the air pump 5 to replenish the protective airbag 4 with gas, restoring it to its initial protective state for subsequent use. This design achieves efficient impact protection for the detector through an intelligent inflation and deflation mechanism, while avoiding the weight increase problem caused by traditional rigid protective structures, thus improving portability and safety. The distributed layout of the annular multi-port pipe 6 and the precise control of the solenoid valve 401 ensure that the pressure adjustment of the protective airbag 4 is fast and uniform, further optimizing the impact resistance of the device and enabling it to work stably in complex outdoor environments.

[0027] Please see Figure 2 The protective outer shell 1 has evenly distributed buckles 9 installed on its inner wall, and the annular multi-port tube 6 is located inside the buckles 9.

[0028] In this invention, the buckle 9 makes the annular multi-port tube 6 locked, which can be better removed during subsequent maintenance and replacement, and at the same time, it remains stable due to the restriction of the buckle 9.

[0029] Example 2:

[0030] Please see Figure 1-4 Based on the above embodiment 1, wherein: an assembly frame 10 is fixedly installed at the bottom of the protective shell 1, a lead screw 1001 is rotatably connected to the inner wall of the assembly frame 10, two synchronous seats 1002 are threadedly connected to the lead screw 1001, evenly distributed movable seats 1003 are rotatably connected to the inner wall of the assembly frame 10, a support leg 1004 is connected to the movable seat 1003, a limit gear 1005 is fixedly installed on the movable seat 1003, two toothed plates 1006 are fixedly installed on the synchronous seats 1002, and the toothed plates 1006 mesh with the limit gear 1005; an adjustment knob 11 is installed on the right side of the assembly frame 10, and the adjustment knob 11 is connected to the right end of the lead screw 1001.

[0031] In this invention, when the detector needs to operate on complex terrains such as muddy ground or water, the user can manually rotate the adjustment knob 11 to drive the lead screw 1001 to rotate. Since the synchronous seat 1002 is threadedly engaged with the lead screw 1001, the rotational motion is converted into linear motion, causing the two synchronous seats 1002 to move along the axial direction of the lead screw 1001.

[0032] As the synchronous seat 1002 moves, the toothed plate 1006 fixed on the synchronous seat 1002 pushes the limit gear 1005 to rotate, which in turn drives the movable seat 1003 to rotate, ultimately causing the outrigger 1004 to unfold or retract. In muddy and soft ground environments, users can adjust the outrigger 1004 to the maximum unfolding angle to increase the support area and prevent the equipment from sinking. When operating in shallow water areas, the outrigger 1004 can be adjusted to a vertically extended state so that the main body 2 of the multi-parameter detector is suspended above the water surface, avoiding water interference.

[0033] After completing the task, rotate the adjustment knob 11 in the opposite direction to retract the outrigger 1004 into the assembly frame 10 for easy carrying. This adjustable outrigger 1004 structure effectively improves the adaptability of the detector, enabling it to work stably in various complex terrain environments without affecting its original impact protection performance.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
