Description

Technical Field

[0001] This invention belongs to the field of water quality analyzer technology, specifically a rapid and accurate water quality analyzer with multiple indicators and its usage method. Background Technology

[0002] Water quality monitoring is of paramount importance as a crucial means of water resource protection and management. Accurate and timely water quality monitoring data provides a solid basis for decisions regarding the rational use of water resources and the prevention and control of water pollution. Long-term water quality monitoring allows for a clear understanding of water quality trends and early warning of potential water quality deterioration events. Generally, water quality monitoring involves multiple indicators, such as water temperature, pH value, dissolved oxygen content, conductivity, and turbidity. These indicators are typically measured using sensors corresponding to water temperature, pH, dissolved oxygen, conductivity, and turbidity. However, this process has the following limitations: Traditional water quality testing methods have many limitations. When conducting tests, they can often only test a single indicator. That is, after testing a corresponding indicator with a certain sensor, the sensor is replaced and another indicator is tested. This process is repeated to complete the testing of multiple indicators. In order to improve the accuracy of the test results, it is often necessary to perform tests at multiple locations. This results in too many repetitive operations in the process of testing multiple indicators, making the operation complex and cumbersome. Summary of the Invention

Each receiver corresponds to a sensor probe and is used to display the index values ​​detected by the sensor probe.

[0013] A preferred method for using a rapid and accurate multi-index water quality analyzer is as follows: S1. Installation: Install multiple sensor probes into their respective mounting slots, and then insert the plugs at the ends of the connecting wires into the corresponding sockets on the integrated electronic control display receiver device to make the sensor probes and receivers electrically connected. S2, Placement: Staff members use a lever to place the n-shaped frame into the water body where multiple indicators need to be tested; S3.

At the same time, when the rotating ring is engaged with the horizontal rotating shaft, the horizontal rotating shaft rotates slowly, which makes it easy to move the sensor probe to different positions. 3) During operation, as the moving sleeve moves to engage the positioning block with the positioning slot, the second connecting rod pulls the pressure block toward the slider, compressing the second spring. The spring force increases the clamping force of the two clamping plates on the sensor probe, improving the installation stability when the sensor probe moves to adjust its position. 4) During operation, a connecting frame is installed on the outside of the pressure block. When the rotating ring separates from the horizontal rotating shaft, the movable magnetic plate on the uppermost connecting frame attracts the fixed magnetic plate, which keeps each sensor probe stable and improves the stability of detection and analysis. When the rotating ring and the horizontal rotating shaft enter the locking state, the pressure block moves to separate the movable magnetic plate from the fixed magnetic plate, which facilitates the position adjustment of the sensor probe.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Depend on Figure 1-8 The present invention relates to a rapid and accurate water quality multi-index analyzer, comprising an integrated electronic control, display and receiving device 1 and multiple sensor probes 3, wherein the integrated electronic control, display and receiving device 1 and the multiple sensor probes 3 are electrically connected by multiple connecting wires 2, and the multiple sensor probes 3 are mounted on a water body detection component 4.

[0020] The water body detection component 4 includes an n-shaped frame 401, with a rotating stirring component 406 for stirring the water body disposed on the inner side of the n-shaped frame 401, and a probe mounting component 407 for mounting each sensor probe 3. The rotating agitator 406 includes a transverse rotating shaft 4063 rotatably mounted inside the n-shaped frame 401. A stirring shaft 4061 is coaxially mounted on the transverse rotating shaft 4063. Stirring blades 4062 are mounted at equal angles on the outer side of the stirring shaft 4061. A fixing column 4065 is mounted on the end of the transverse rotating shaft 4063 away from the stirring shaft 4061. Positioning grooves 4066 are opened at equal angles on the fixing column 4065. Two limiting plates 4064 are mounted on the transverse rotating shaft 4063. The two limiting plates 4064 limit the rotating ring 4071. The diameter of the fixing column 4065 is larger than the diameter of the transverse rotating shaft 4063. One end of the transverse rotating shaft 4063 is connected to a rotating drive component 408.

[0021] The probe mounting component 407 includes a rotating ring 4071 rotatably mounted on a transverse rotating shaft 4063. Multiple sensor probes 3 are installed in multiple mounting slots 4073, facilitating multi-index analysis and detection of the water body. Simultaneously, by rotating synchronously with the transverse rotating shaft 4063, the rotating ring 4071 can move multiple sensor probes 3 to different positions, facilitating multi-point detection at different locations and depths, thus improving the accuracy of water quality detection. Side plates 4072 are mounted at equal angles on the outer side of the rotating ring 4071. Mounting slots 4073 are provided on the side plates 4072, and probe clamping components are provided on the side plates 4072. A snap-fit ​​fastener 409 is provided on the side of the ring 4071 near the fixed post 4065. The sensor probe 3 is clamped by the movement of the snap-fit ​​fastener 409, and can rotate after cooperating with the positioning groove 4066 to adjust the depth of the sensor probe 3. When the rotating ring 4071 is separated from the transverse rotating shaft 4063, the transverse rotating shaft 4063 rotates quickly to stir the water, so that the components of the water are evenly distributed, further improving the detection accuracy. At the same time, when the rotating ring 4071 is snapped with the transverse rotating shaft 4063, the transverse rotating shaft 4063 rotates slowly, which makes it easy to move the sensor probe 3 to different positions.

[0022] The probe holder includes two clamping plates 4074 symmetrically arranged inside the mounting groove 4073. Connecting rods 4075 are symmetrically arranged on the opposite sides of the two clamping plates 4074. The connecting rods 4075 are slidably connected to the side plate 4072. A movable plate 4076 is mounted on one end of the connecting rod 4075. Two movable plates 4076 are symmetrically arranged on both sides of the side plate 4072. First springs 4077 are symmetrically installed between the movable plates 4076 and the side walls of the side plate 4072. A sliding groove 4078 is formed inside the side plate 4072, located near the mounting groove 4073. On one side of the rotating ring 4071, a slider 4079 is slidably installed inside the slide groove 4078. Two first connecting rods 40710 are symmetrically hinged on both sides of the slider 4079. The other ends of the two first connecting rods 40710 are respectively hinged to two movable plates 4076. The first connecting rods 40710 are slidably installed inside the slide groove 4078. The first connecting rods 40710 are located on the side of the slider 4079 away from the rotating ring 4071. A second spring 40712 is installed between the slider 4079 and the pressure block 40711. A suction fixing member is provided on the outside of the pressure block 40711.

[0023] The suction fixing component includes a connecting frame 40713 fixedly connected to the pressure block 40711. The connecting frame 40713 is located outside the sensor probe 3. The movement of the connecting frame 40713 will not affect the fixation of the sensor probe 3. A movable suction magnetic plate 40714 is fixedly installed at the end of the connecting frame 40713 away from the rotating ring 4071. A fixed suction magnetic plate 40715 is fixedly installed on the inner top wall of the n-shaped frame 401. The movable suction magnetic plate 40714 on the uppermost connecting frame 40713 is attracted to the fixed suction magnetic plate 40715. A connecting frame 40713 is installed on the outside of the pressure block 40711. When the rotating ring 4071 is separated from the transverse rotating shaft 4063, the movable magnetic plate 40714 on the uppermost connecting frame 40713 is attracted to the fixed magnetic plate 40715, so that each sensor probe 3 remains stable and the detection and analysis stability is improved. When the rotating ring 4071 and the transverse rotating shaft 4063 enter the snap-fit ​​state, the pressure block 40711 moves to separate the movable magnetic plate 40714 from the fixed magnetic plate 40715, which facilitates the position adjustment of the sensor probe 3.

[0024] The snap-fit ​​fastener 409 includes a movable sleeve 4091 disposed on the side of the rotating ring 4071 near the fixed post 4065. A positioning block 4094 is installed at equal angles on the inner side of the movable sleeve 4091. After the movable sleeve 4091 moves towards the fixed post 4065, it can be fitted onto the outer side of the fixed post 4065, and the positioning block 4094 snaps into the positioning groove 4066. A second connecting rod 4092 is installed at equal angles on the outer side of the movable sleeve 4091. The other ends of multiple second connecting rods 4092 are respectively hinged to each pressure block 40711. A wire limiting block 4093 is installed at equal angles on the outer side of the movable sleeve 4091. When the sensor probe 3 is installed, the connecting wire 2 passes through the wire limiting block 4093 for limitation. A movable groove 4095 is opened at equal angles inside the rotating ring 4071. A movable block 4096 is movably installed inside the movable groove 4095. A fixed part is installed on the side of the movable block 4096 near the movable sleeve 4091. Push rod 4097, one end of push rod 4097 extends to the outside of rotating ring 4071, and push rod 4097 is fixedly connected to movable sleeve 4091. Movable block 4096 is fixedly installed with a third spring 4098 on the side near movable sleeve 4091. One end of third spring 4098 is fixedly connected to the inner wall of end of movable groove 4095. Magnetic block 4099 is fixedly installed on movable block 4096. Electromagnet 40910 is fixedly installed on the inner wall of end of movable groove 4095 away from movable sleeve 4091. During the process of movable sleeve 4091 moving to engage positioning block 4094 with positioning groove 4066, the second connecting rod 4092 pulls pressure block 40711 toward slider 4079, causing second spring 40712 to be compressed. The elastic force of second spring 40712 increases the clamping force of two clamping plates 4074 on sensor probe 3, improving the installation stability of sensor probe 3 when moving for position adjustment.

[0025] The rotation drive component 408 includes a first pulley 4081 coaxially fixedly mounted on one end of a transverse rotating shaft 4063, a second pulley 4082 disposed above the first pulley 4081, a transmission belt 4084 disposed on the outer side of the first pulley 4081 and the second pulley 4082, the second pulley 4082 being coaxially mounted on the output shaft of a drive motor 4083, a mounting bracket 402 fixedly mounted on the top of an n-shaped frame 401, the drive motor 4083 being fixedly mounted on the mounting bracket 402, and a handle 403 mounted on the top of the mounting bracket 402.

[0026] A hanger 404 is installed on the n-type frame 401. A waterproof camera 405 is fixedly installed at the end of the hanger 404. The waterproof camera 405 is used to capture images of the probe mounting component 407 and the rotation drive component 408. The integrated electronic control display and receiving device 1 consists of a controller, a display, and various receivers. The controller is used to control electronic equipment such as the drive motor 4083 and the electromagnet 40910. The display is used to display the images captured by the waterproof camera 405. Each receiver corresponds to each sensor probe 3 and is used to display the index values ​​detected by the sensor probe 3.

[0027] Working principle: During operation, multiple sensor probes 3 are first installed inside each mounting slot 4073. These multiple sensor probes 3 include, but are not limited to, water temperature sensors, pH sensors, dissolved oxygen sensors, conductivity sensors, and turbidity sensors. The sensor probes 3 are inserted between two clamping plates 4074 inside the mounting slot 4073. The two clamping plates 4074 clamp the sensor probes 3 by the elastic force of the first spring 4077. The connecting wire 2 connected to the sensor probe 3 is passed through the wire limiting block 4093 and then its plug is inserted into the corresponding socket on the integrated electronic control display receiver 1, so that the receiver and the sensor probe 3 are connected accordingly, and the installation is completed. The staff member holds the handle 403 and inserts the n-shaped frame 401 into the water body that needs to be tested. At this time, the drive motor 4083 is turned on, which drives the second pulley 4082 to rotate. The second pulley 4082 and the first pulley 4081 at the end of the transverse rotating shaft 4063 are connected by a transmission belt 4084. Thus, the drive motor 4083 can drive the transverse rotating shaft 4063 to rotate. The stirring blade 4062 stirs the water body, improves the uniformity of the components in the water body, and thus improves the accuracy of the test structure. After mixing, multi-index analysis is performed through each sensor probe 3, and the detected structure is transmitted to the receiver for display. During stirring, the controller needs to adjust the output shaft speed of the drive motor 4083 to a faster state. After stirring is completed, the controller adjusts the output shaft speed of the drive motor 4083 to a slower state. Then, the controller controls the electromagnet 40910 to be energized. The electromagnets 40910 are connected in series, so that the electromagnets 40910 generate a repulsive force on the magnetic block 4099, thereby pushing the moving sleeve 4091 to move towards the fixed column 4065. When the positioning block 4094 does not correspond to the positioning groove 4066, the end face of the positioning block 4094 contacts the end face of the fixed column 4065. When the positioning block 4094 corresponds to the positioning groove 4066, the positioning block 4094 is inserted into the positioning groove 4066. At this time, the transverse rotating shaft 4063 rotates, driving the rotating ring 4071 to rotate synchronously. Simultaneously, as the movable sleeve 4091 moves toward the fixed column 4065, each second connecting rod 4092 pulls each pressure block 40711 toward the slider 4079, causing the second spring 40712 to be compressed. Under the elastic force of the second spring 40712, the clamping force of the two clamping plates 4074 on the sensor probe 3 is increased, thereby improving the fixed stability of the sensor probe 3 during position adjustment. After the uppermost pressure block 40711 moves, it drives the uppermost connecting frame 40713 to move downward, causing the movable magnetic plate 40714 to separate from the fixed magnetic plate 40715, thus facilitating the rotation of the rotating ring 4071 to adjust the position of each sensor probe 3. When the other side plate 4072 is rotated to the top position, the electromagnet 40910 is de-energized, and the moving sleeve 4091 moves back under the elastic force of the third spring 4098. At this time, the uppermost connecting frame 40713 moves upward, so that the movable magnetic plate 40714 and the fixed magnetic plate 40715 are attracted, thereby fixing the position of each sensor probe 3. When the sensor probe 3 is adjusted, the staff can observe its status through the waterproof camera 405 to facilitate position adjustment. Then the above operation is repeated so that the sensor probe 3 can stay at different heights and positions in the water body, thereby enabling multi-point detection and analysis of different positions in the water body and improving the accuracy of water quality detection. After the test is completed, remove the water detection component 4 from the water and disassemble the sensor probe 3.
