[0078] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0079] It should be noted that during the grinding and beneficiation process, some production stages require sampling and analysis of the slurry on the production line to assess the production status based on the analysis results. In related technologies, slurry sampling is often performed manually by operators using sampling tools. However, in practical applications, it has been found that because the slurry concentration varies at different depths within the slurry channel, if operators only sample at a certain depth within the channel, the concentration of the collected slurry sample will differ significantly from the average concentration of the slurry on the production line. This results in poor sample representativeness, distorted slurry analysis results, and is detrimental to ensuring stable production. Furthermore, the sampling workload for operators is substantial, increasing the cost of sampling operations.

[0080] In view of this, such as Figures 1 to 6 As shown, a fluid sampling device 100 is provided according to a first aspect of the present disclosure, comprising: a flow guiding assembly 110 having an inlet end 1101, an outlet end 1102, and a sampling channel, the sampling channel being connected between the inlet end 1101 and the outlet end 1102, the inlet end 1101 being disposed within a fluid flow channel 200'; a cleaning assembly 120 being connected between a liquid supply device and the flow guiding assembly 110, the cleaning assembly 120 being used to guide the cleaning liquid output by the liquid supply device to flow towards the sampling channel; a power assembly 130 being connected to the flow guiding assembly 110, for driving the fluid medium in the sampling channel to flow towards the outlet end 1102; and a drive assembly 140 being connected to the flow guiding assembly 110, for driving the inlet end 1101 to move, thereby adjusting the position of the inlet end 1101 in the depth direction of the fluid flow channel 200'.

[0081] The fluid sampling device 100 provided in this embodiment includes the aforementioned flow guiding component 110, cleaning component 120, power component 130, and drive component 140. The flow guiding component 110 has an inlet end 1101, an outlet end 1102, and a sampling channel connecting the inlet end 1101 and the outlet end 1102. The inlet end 1101 can be disposed within a fluid channel 200' to allow the inlet end 1101 to access the fluid to be sampled 300' within the fluid channel 200'. When the power component 130 operates, it can create a certain pressure gradient within the sampling channel, causing the fluid within the sampling channel to flow towards the outlet end 1102, thereby improving the flow of the fluid at the inlet end 1101. When the inlet 1101 is immersed in the fluid to be sampled 300' within the aforementioned fluid flow channel 200', the fluid sampling device 100 can use the operation of the power component 130 to draw the fluid to be sampled 300' into the inlet 1101, and can use the sampling channel to guide the drawn-in fluid to be sampled 300' to the outlet 1102, thereby facilitating the collection of the fluid to be sampled 300' at the outlet 1102, so as to achieve sample collection of the fluid to be sampled 300'; the aforementioned cleaning component 120 is adapted to guide the cleaning fluid output by the industrial device to The aforementioned sampling channel facilitates the cleaning of the interior of the flow guide component 110 with cleaning fluid, improving the maintenance convenience of the flow guide component 110 and reducing the risk of blockage. The aforementioned driving component 140 can drive the flow guide component 110, causing the aforementioned sample inlet 1101 to move within a certain depth range of the aforementioned fluid channel 200'. Thus, the fluid sampling device 100 is suitable for drawing in the fluid to be sampled 300' at different depth positions within the aforementioned fluid channel 200' by driving the sample inlet 1101 to move in the depth direction of the fluid channel 200' during the operation of the power component 130. The fluid sample output by the sample outlet 1102 can include the fluid to be sampled 300' at the aforementioned different depth positions, which can improve the representativeness of the fluid sample, reduce the difference between the concentration of the fluid sample and the concentration of the fluid to be sampled 300' within the fluid channel 200', provide a guarantee for the reliability of the sample analysis results, improve the stability of production, reduce the manpower consumption and execution cost of sampling operations, and improve the execution efficiency of sampling operations.

[0082] It should be noted that the fluid sampling device 100 provided in this embodiment can be applied to grinding and beneficiation production in practical applications, for example, to collect samples of slurry on the grinding and beneficiation production line.

[0083] like Figures 1 to 6As shown, taking the fluid sampling device 100 for sampling slurry from a grinding and beneficiation production line as an example, the aforementioned fluid channel 200' can be, but is not limited to, slurry pipes, buffer tanks, buffer containers, or slurry ditches on the grinding and beneficiation production line, or other equipment used for transporting or buffering slurry. The aforementioned fluid sampling device 100 can be installed in the aforementioned fluid channel 200', and the aforementioned sample inlet 1101 can be located inside the aforementioned fluid channel 200' so that the sample inlet 1101 can contact the slurry within the fluid channel 200'; the arrangement position of the aforementioned flow guiding component 110 can be selected according to actual needs, for example, such as... Figures 1 to 4 As shown, the flow guiding component 110 can be arranged in a manner not higher than the fluid flow channel 200', or as... Figure 5 and Figure 6 As shown, the flow guiding component 110 can be arranged in a manner no less than the fluid flow channel 200', and the specific arrangement can be determined based on the actual conditions of the fluid flow channel 200' at the production site. Figure 1 and Figure 2 The illustration schematically depicts a scenario where a fluid acquisition device is installed in a slurry pipeline at a height not exceeding 200' above the fluid flow channel. Figure 3 and Figure 4 The illustration schematically depicts a scenario where a fluid collection device is installed in a buffer tank, buffer container, or slurry channel with a fluid flow channel at least 200' deep. Figure 5 and Figure 6 The illustration schematically depicts a scenario where a fluid collection device is installed in a buffer tank, buffer container, or slurry channel at a height not exceeding 200' above the fluid flow channel.

[0084] like Figures 1 to 6 As shown, the aforementioned driving component 140 can drive the aforementioned sample inlet 1101 to move between a first depth position and a second depth position. The aforementioned first depth position and second depth position are two different positions in the depth direction of the fluid channel 200'. For example, the aforementioned first depth position can be the bottom position of the fluid channel 200', and the aforementioned second depth position can be the liquid surface position of the fluid 300' to be sampled within the fluid channel 200'. Figure 1 , Figure 3 and Figure 5 The illustration schematically shows the scenario when the injection end 1101 is located at the aforementioned first depth position. Figure 2 , Figure 4 and Figure 6The illustration schematically depicts a scenario where the sample inlet 1101 is located at the aforementioned second depth position. Based on this, the fluid sampling device 100 is adapted to draw in slurry at different depth positions within the aforementioned fluid channel 200' by driving the sample inlet 1101 to move between the first and second depth positions during the operation of the power component 130. This allows the slurry sample output by the sample outlet 1102 to include slurry at the aforementioned different depth positions, thereby improving the representativeness of the slurry sample, reducing the difference between the slurry sample concentration and the slurry concentration within the fluid channel 200', ensuring the reliability of the slurry sample analysis results, improving the stability of grinding and beneficiation production, reducing manpower consumption and execution costs in slurry sampling operations, and improving the execution efficiency of slurry sampling operations.

[0085] It is understandable that, in practical applications, the depth direction of the aforementioned fluid channel 200' is consistent with the direction of gravity. Figures 1 to 6 The center line S with an arrowhead is used to schematically represent the aforementioned depth direction.

[0086] It is understood that the range of motion of the aforementioned sample inlet 1101 under the drive of the aforementioned drive component 140 can be determined by the liquid level height of the sampled fluid 300' in the aforementioned fluid channel 200' or set according to the maximum depth of the fluid channel 200', so that the aforementioned sample inlet 1101 can pass through the sampled fluid 300' at different depth positions during the movement.

[0087] It is understood that the aforementioned drive component 140 can output, but is not limited to, rotational or translational motion; the aforementioned drive component 140 can be, but is not limited to, pneumatic, electric, hydraulic, or other types of drive components 140; the drive component 140 can drive the aforementioned sample inlet 1101 to move along the depth direction of the aforementioned fluid channel 200'.

[0088] It is understandable that, in the case that the aforementioned fluid flow channel 200' is a pressureless flow channel, the head of the aforementioned power component 130 only needs to meet the backend requirements.

[0089] It is understood that the aforementioned cleaning fluid can be, but is not limited to, water; correspondingly, the aforementioned liquid supply device can include a water supply pipeline or a water storage device on the production line, that is, the aforementioned cleaning component 120 can be connected between the aforementioned water supply pipeline and the aforementioned flow guiding component 110, or connected between the output end of the aforementioned water storage device and the flow guiding component 110. In practical applications, the aforementioned cleaning component 120 can have a pressure regulating part, which is used to adjust the pressure of the cleaning fluid flowing to the aforementioned sampling channel. For example, the aforementioned pressure is slightly higher than the pressure at the lowest position of the aforementioned fluid flow channel 200'. For example, the aforementioned pressure can be 0.01 MPa higher than the pressure at the lowest position of the aforementioned fluid flow channel 200', so that the cleaning fluid can flow to the aforementioned sample inlet 1101.

[0090] In some feasible examples, the fluid sampling device 100 may include the aforementioned liquid supply device.

[0091] In some feasible examples, the fluid sampling device 100 may also include a sample detection device, the inlet of which is connected to the outlet 1102; or, the fluid sampling device 100 may also include a sample tank, the sample tank being connected to the outlet 1102.

[0092] like Figures 1 to 6 As shown, in some examples, the flow guiding assembly 110 includes: a first tube 111 having a first channel and an inlet end 1101; a second tube 112 having a second channel and an outlet end 1102, the first tube 111 being connected to the second tube 112, and the sampling channel including the first channel and the second channel; wherein, the driving assembly 140 is connected to the first tube 111 and is used to drive the first tube 111 to move, so as to adjust the position of the inlet end 1101 in the depth direction of the fluid channel 200'.

[0093] In this technical solution, the flow guiding component 110 may include the aforementioned first tube 111 and the aforementioned second tube 112. Based on the aforementioned configuration, the sample inlet 1101 and the sample outlet 1102 of the flow guiding component 110 can be located in two tubes respectively, thereby facilitating the fixation of the sample outlet 1102 while allowing the sample inlet 1101 to be movable. That is, the aforementioned first tube 111 can be configured to have a certain degree of freedom of movement, and the aforementioned second tube 112 can be fixedly installed in practical applications, thereby facilitating the stable discharge of fluid samples by the fluid sampling device 100 and improving the stability of the sampling process. Correspondingly, the aforementioned driving component 140 can drive the aforementioned first tube 111 to change the position of the aforementioned sample inlet 1101 in the depth direction of the aforementioned fluid flow channel 200'.

[0094] It is understood that the aforementioned first channel refers to the internal space of the aforementioned first pipe fitting 111, and the aforementioned second channel refers to the internal space of the aforementioned second pipe fitting 112. The aforementioned first channel and the aforementioned second channel are connected.

[0095] It is understood that the aforementioned first fitting 111 may also have a first connecting end, the first connecting end and the aforementioned sample inlet 1101 being opposite ends of the aforementioned first fitting 111, and the aforementioned first channel connecting the aforementioned first connecting end and the aforementioned sample inlet 1101; the aforementioned second fitting 112 may also have a second connecting end, the second connecting end and the aforementioned sample outlet 1102 being opposite ends of the aforementioned second fitting 112, and the aforementioned second channel connecting the aforementioned second connecting end and the aforementioned sample outlet 1102. The aforementioned first connecting end and the aforementioned second connecting end may be sealed together.

[0096] like Figures 1 to 6 As shown, in some examples, a first tube 111 passes through a second tube 112, the first tube 111 being adapted to move along the extension direction of the second tube 112 so that the injection end 1101 can extend or retract into the second tube 112; wherein, the second tube 112 is arranged to extend along the depth direction of the fluid flow channel 200'.

[0097] In this technical solution, the aforementioned first tube 111 can be inserted through the aforementioned second tube 112 and is adapted to move along the extension direction of the second tube 112, thereby making the position of the aforementioned sample inlet 1101 adjustable. Correspondingly, the aforementioned second tube 112 can be arranged along the depth direction of the aforementioned fluid channel 200'. Thus, on the one hand, during the movement of the first tube 111 along the extension direction of the second tube 112, the position of the sample inlet 1101 in the depth direction of the aforementioned fluid channel 200' can change, thereby facilitating the sample inlet 1101 to access the sampled fluid 300' at different depth positions. On the other hand, the fluid sampling device 100 can use the second tube 112 to provide guidance for the movement of the first tube 111, which is beneficial to improving the movement stability of the first tube 111. Furthermore, the flow guiding component 110 has a telescopic structure, which is beneficial to improving the structural compactness of the flow guiding component 110.

[0098] It is understood that the extension direction of the aforementioned second pipe fitting 112 refers to the axial direction of the second pipe fitting 112.

[0099] It is understandable that, such as Figures 1 to 6 As shown, in practical applications, the second fitting 112 can be installed at the bottom or top of the aforementioned fluid flow channel 200'. The specific installation can be set according to the actual installation conditions of the production site, and no further restrictions are imposed here.

[0100] In some feasible examples, the first fitting 111 and the second fitting 112 have a sliding seal fit.

[0101] like Figures 1 to 6 As shown, in some feasible examples, the fluid sampling device 100 further includes: a limiting component 170, including a first limiting part 171 and a second limiting part 172, the first limiting part 171 and the second limiting part 172 being disposed at intervals within the second tube 112; and a driving component 140 for driving the first tube 111 to move along the extension direction of the second tube 112, so that the sample inlet 1101 moves between a first depth position and a second depth position, the aforementioned first depth position and second depth position being two different positions in the depth direction of the fluid flow channel 200'; wherein, when the sample inlet 1101 is located at the first depth position, the first limiting part 171 is limited and engaged with the first tube 111; and when the sample inlet 1101 is located at the second depth position, the second limiting part 172 is limited and engaged with the first tube 111.

[0102] In this technical solution, the fluid sampling device 100 may also include the aforementioned limiting component 170; based on the aforementioned configuration, the fluid sampling device 100 can use the limiting component 170 to constrain the movement stroke of the first tube 111 in the extension direction of the second tube 112, thereby improving the movement stability and reliability of the aforementioned sample inlet 1101 and reducing the risk of mutual separation between the first tube 111 and the second tube 112.

[0103] It is understood that in practical applications, the aforementioned first depth position can be the bottom position of the aforementioned fluid channel 200', and the aforementioned second depth position can be the liquid surface position of the fluid to be sampled 300' within the aforementioned fluid channel 200'.

[0104] It is understood that the aforementioned first limiting part 171 and the aforementioned second limiting part 172 may both have a limiting state and a releasing state. In the aforementioned limiting state, the corresponding limiting part is adapted to limit and cooperate with the aforementioned first pipe fitting 111. In the aforementioned releasing state, the limiting relationship between the corresponding limiting part and the aforementioned first pipe fitting 111 is released, thereby facilitating the application of limiting or release of limiting on the first pipe fitting 111 according to actual needs.

[0105] In some examples, the second fitting 112 is a telescopic structure and is arranged to extend and retract along the depth direction of the fluid channel 200'.

[0106] In this technical solution, the aforementioned second pipe 112 can be a telescopic structure. Thus, when the aforementioned sample outlet 1102 is fixedly set, the second pipe 112 can reduce the movement restriction on the first pipe 111 by telescopic deformation, which facilitates the displacement of the first pipe 111 under the drive of the drive assembly 140. Accordingly, in practical applications, the telescopic direction of the second pipe 112 can be set to be consistent with the depth direction of the fluid flow channel 200', thereby improving the adaptability of the telescopic direction of the second pipe 112 to the movement direction of the first pipe 111 and reducing the influence of the second pipe 112 on the movement of the first pipe 111.

[0107] For example, the aforementioned second fitting 112 may be a telescopic hose.

[0108] like Figures 1 to 6 As shown, in some examples, the drive assembly 140 includes: a drive section; and a transmission section 142 connected between the first pipe 111 and the drive section, the drive section being used to drive the first pipe 111 to move along the extension direction of the second pipe 112 via the transmission section 142.

[0109] In this technical solution, the drive assembly 140 may include the aforementioned drive unit and the aforementioned transmission unit 142. Based on the aforementioned configuration, the drive assembly 140 can use the drive unit to provide power for the movement of the sample inlet 1101, and the drive unit can indirectly drive the first tube 111 through the transmission unit 142, which is beneficial to improve the stability of the motion output of the drive assembly 140 and provide a guarantee for the stable movement of the sample inlet 1101.

[0110] It is understandable that the aforementioned transmission unit 142 can have various transmission forms, and no further limitations are made here.

[0111] It should be noted that, Figures 1 to 6 The aforementioned drive unit is omitted. It is understood that the aforementioned drive unit can output, but is not limited to, rotational or translational motion; the aforementioned drive unit can be, but is not limited to, pneumatic, electric, hydraulic, or other types of drive components; the drive unit can drive the aforementioned sample inlet 1101 to move along the depth direction of the aforementioned fluid channel 200' via the transmission unit 142.

[0112] like Figures 1 to 6 As shown, in some examples, the transmission unit 142 includes: a crank 1421 connected to a drive unit for driving the crank 1421 to rotate; and a connecting rod 1422, one end of which is hinged to the first tube 111 and the other end of which is hinged to the crank 1421.

[0113] In this technical solution, the transmission part 142 may include the aforementioned crank 1421 and the aforementioned connecting rod 1422; based on the aforementioned configuration, the transmission part 142 can transmit power between the drive part and the first tube 111 by means of the connecting rod 1422, which is beneficial to further improve the motion stability of the first tube 111 while simplifying the structure of the transmission part 142 and reducing the manufacturing and maintenance costs of the transmission part 142.

[0114] It should be noted that, Figures 1 to 6 In the diagram, the hollow arc-shaped arrow is used to schematically indicate the direction of rotation of crank 1421.

[0115] like Figures 1 to 6 As shown, in some examples, the second fitting 112 includes: a tee pipe 1121 having a first port, a second port, and a third port; a first flow pipe 1122 through which the first fitting 111 is movably inserted; a second flow pipe 1123 having a sample outlet 1102, and a power assembly 130 disposed in the second flow pipe 1123; a first shut-off valve 1124 connected between the first port and the first flow pipe 1122; a second shut-off valve 1125 connected between the second port and the second flow pipe 1123; wherein the cleaning assembly 120 is connected to the third port.

[0116] In this technical solution, the second pipe fitting 112 may include the aforementioned three-way pipe 1121, first flow pipe 1122, second flow pipe 1123, first shut-off valve 1124, and second shut-off valve 1125. Based on the aforementioned configuration, if the portion of the flow guiding assembly 110 located between the aforementioned first port and the aforementioned sample inlet 1101 is considered as the sample inlet section of the flow guiding assembly 110, and the portion of the flow guiding assembly 110 located between the aforementioned second port and the aforementioned sample outlet 1102 is considered as the sample outlet section of the flow guiding assembly 110, then when the aforementioned first shut-off valve 1124 is open and the second shut-off valve 1125 is closed, the cleaning fluid output by the cleaning assembly 120 can flow through the interior of the aforementioned sample inlet section, thereby achieving backwashing of the aforementioned sample inlet section and improving the aforementioned sample inlet performance. The cleanliness of the flow path in the sample injection zone reduces the probability of blockage. Correspondingly, when the first shut-off valve 1124 is closed and the second shut-off valve 1125 is open, the cleaning fluid output by the cleaning component 120 can flow through the interior of the sample outlet zone, thereby flushing the sample outlet zone and improving the cleanliness of the flow path in the sample outlet zone, thus reducing the probability of blockage. Based on this, the fluid sampling device 100 can control the flow direction of the cleaning fluid output by the cleaning component after entering the sampling channel by adjusting the on / off state of the first shut-off valve 1124 and the second shut-off valve 1125, thereby controlling the cleaning area when cleaning the flow guide component 110, which is beneficial to ensuring the cleaning effect of the cleaning component 120 on the flow guide component 110.

[0117] It is understood that the aforementioned cleaning component 120 may have an output state and a stop state. In the aforementioned output state, the aforementioned liquid supply device can be connected to the aforementioned sampling channel through the aforementioned cleaning component 120, so that the cleaning liquid can flow into the aforementioned sampling channel under the guidance of the cleaning component 120 and rinse the interior of the aforementioned guide component 110. In the aforementioned stop state, the aforementioned liquid supply device is cut off from the aforementioned sampling channel. In this case, the cleaning component 120 can prevent the cleaning liquid from flowing into the sampling channel.

[0118] It is understood that the aforementioned first shut-off valve 1124 is used to connect or disconnect the aforementioned first port and the aforementioned first flow pipe 1122, and the aforementioned second shut-off valve 1125 is used to connect or disconnect the aforementioned second port and the aforementioned second flow pipe 1123. During the process of collecting fluid samples using the fluid sampling device, the aforementioned first shut-off valve 1124 and the aforementioned second shut-off valve 1125 can be controlled to be connected simultaneously, and the aforementioned power assembly 130 can be controlled to operate, so that the sample can flow from the aforementioned inlet end 1101 to the aforementioned outlet end 1102.

[0119] It is understood that when the aforementioned cleaning fluid flows through the aforementioned sample inlet section, the cleaning fluid can flush the interior of the aforementioned first shut-off valve 1124, the first flow pipe 1122, and the first pipe fitting 111; when the aforementioned cleaning fluid flows through the aforementioned sample outlet section, the cleaning fluid can flush the aforementioned second shut-off valve 1125, the second flow pipe 1123, and the power assembly 130.

[0120] like Figures 1 to 6 As shown, in some examples, the cleaning assembly 120 includes: a liquid guide tube 121 for connecting between the third port and the liquid supply device; and a third shut-off valve 122 disposed on the liquid guide tube 121 for opening or closing the liquid guide tube 121.

[0121] In this technical solution, the cleaning assembly 120 may include the aforementioned liquid guide tube 121 and the aforementioned third shut-off valve 122. Based on the aforementioned configuration, when the aforementioned third shut-off valve 122 is open, the aforementioned third port is connected to the aforementioned liquid supply device, so that the cleaning fluid output by the liquid supply device can flow into the aforementioned third port through the cleaning assembly 120, so that the cleaning fluid can clean the interior of the guide assembly 110. When the aforementioned third shut-off valve 122 is closed, the aforementioned third port is cut off from the aforementioned liquid supply device. In this case, the cleaning assembly 120 can prevent the cleaning fluid from flowing into the sampling channel, so that the fluid sampling device can collect fluid samples. Thus, the output controllability of the cleaning assembly 120 can be improved, and the ease of use of the fluid sampling device can be enhanced.

[0122] In some examples, the power assembly 130 includes a sampling pump disposed in the flow guiding assembly 110 for driving the fluid medium in the sampling channel to flow toward the sample outlet 1102.

[0123] In this technical solution, the power component 130 may include the aforementioned sampling pump; based on the aforementioned configuration, the fluid sampling device can use the sampling pump to provide power for the fluid flow in the sampling channel, so that the fluid sample connected to the inlet 1101 can flow stably to the outlet 1102, thereby improving the sample collection efficiency.

[0124] For example, the aforementioned sampling pump can be a variable frequency sampling pump or a variable displacement pump, which facilitates the adjustment of the output flow rate of the sampling pump, thereby improving the controllability of the sampling volume and sampling speed.

[0125] like Figures 1 to 6 As shown, in some examples, the fluid sampling device 100 further includes a monitoring component 150 disposed on the flow guiding component 110 for collecting fluid flow information within the sampling channel.

[0126] In this technical solution, the fluid sampling device 100 may also include the aforementioned monitoring component 150; based on the aforementioned configuration, the flow information collected by the aforementioned monitoring component 150 can be used to characterize the output flow of the aforementioned power component 130 or the output flow of the aforementioned sampling end 1102, which is convenient to provide reference information for adjusting the operating parameters of the power component 130 in practical applications, and is conducive to improving the stability and controllability of the sampling process.

[0127] For example, the aforementioned monitoring component 150 may include a flow meter. When the flow guiding component 110 includes the aforementioned second flow pipe 1123, the aforementioned flow meter may be installed on the aforementioned second flow pipe 1123 and arranged between the aforementioned power component 130 and the aforementioned sample outlet 1102, thereby facilitating the more accurate reflection of the aforementioned flow information on the output flow of the power component 130 or the output flow of the sample outlet 1102.

[0128] like Figure 7 As shown, in some feasible examples, the fluid sampling device 100 further includes a control component 160, to which the aforementioned flow guiding component 110, power component 130, drive component 140, cleaning component, limiting component 170 and monitoring component 150 are all signal-connected.

[0129] In this technical solution, the fluid sampling component may also include the aforementioned control component 160; based on the aforementioned configuration, the fluid sampling device 100 can use the aforementioned control component 160 to control the operating status or operating parameters of other components, which is beneficial to improving the controllability and automation level of the fluid sampling device 100.

[0130] For example, the control component 160 may include a control unit 161 and a human-machine interface 162. The human-machine interface 162 has a human-machine interface for receiving control commands input by the operator. The human-machine interface 162 is signal-connected to the control unit 161, so that the control commands can be transmitted to the control unit 161. Correspondingly, the control unit 161 is signal-connected to the first shut-off valve 1124, the second shut-off valve 1125, the third shut-off valve 122, the power component 130, the first limit part 171, and the second limit part 172, so that the control unit 161 can perform corresponding operation control on the aforementioned components or parts based on the aforementioned control commands. The monitoring component 150 is signal-connected to the control unit 161, so that the flow information collected by the monitoring component 150 can be transmitted to the control unit 161, so that the control unit 161 can adjust the output flow of the power component 130 according to the aforementioned flow information.

[0131] It is understood that the aforementioned control unit 161 may include a CPU (Central Processing Unit); the aforementioned human-computer interaction unit 162 may include a touch screen.

[0132] like Figure 8 As shown, a control method for a fluid sampling device 100 is provided according to a second aspect of the present disclosure, for use in the fluid sampling device 100 as described in any of the first aspects above, the control method comprising:

[0133] Step S801: In response to a sampling command, control the fluid sampling device 100 to perform a sampling action at least once; the sampling action includes: controlling the power component 130 to operate; controlling the drive component 140 to drive the injection end 1101 to move from a first depth position to a second depth position, the first depth position and the second depth position being two different positions in the depth direction of the fluid flow channel 200'; when the injection end 1101 moves from the first depth position to the second depth position, control the drive component 140 to drive the injection end 1101 to move from the second depth position to the first depth position; when the injection end 1101 moves from the second depth position to the first depth position, control the power component 130 and the drive component 140 to shut down.

[0134] Specifically, the aforementioned fluid sampling device 100 can respond to the aforementioned sampling execution and perform the aforementioned sampling action at least once. Accordingly, during the execution of the sampling action, the aforementioned inlet end 1101 can reciprocate once between the aforementioned first depth position and the second depth position while the aforementioned power component 130 is in operation, thereby drawing in the sampled fluid 300' within a certain depth range in the aforementioned fluid channel 200'. This ensures that the fluid sample output by the sampling end 1102 can include the sampled fluid 300' at the aforementioned different depth positions, improving the representativeness of the fluid sample, reducing the difference between the fluid sample concentration and the concentration of the sampled fluid 300' within the fluid channel 200', ensuring the reliability of the sample analysis results, improving production stability, reducing manpower consumption and execution costs in sampling operations, and improving the execution efficiency of sampling operations. Furthermore, after each sampling action is completed, the inlet end can be reset to the aforementioned first depth position to facilitate subsequent re-execution of the sampling action, reducing the position adjustment process of the inlet end 1101 before participating in the sampling action and improving efficiency.

[0135] It is understandable that the aforementioned sampling instructions can be issued manually by the operators or automatically generated under certain conditions. In other words, there can be multiple ways and timing for the generation of sampling instructions, which will not be limited here.

[0136] It is understood that in practical applications, the aforementioned first depth position and second depth position are two different positions in the depth direction of the fluid channel 200'. For example, the aforementioned first depth position may be the bottom position of the fluid channel 200', and the aforementioned second depth position may be the liquid surface position of the fluid to be sampled 300' within the fluid channel 200', which helps to increase the depth range corresponding to the fluid sample and enhance the representativeness of the fluid sample.

[0137] It is understood that the aforementioned sampling action may include, before controlling the power assembly 130 to operate, obtaining the current position information of the injection end 1101; accordingly, if it is determined that the injection end 1101 is located at the aforementioned first depth position, the power assembly 130 may be controlled to operate to continue the subsequent process of the sampling action; if it is determined that the injection end 1101 is not located at the aforementioned first depth position, the power assembly 130 may be controlled to drive the liquid inlet end from the current position to the aforementioned first depth position, and then the power assembly 130 may be controlled to operate to continue the subsequent process of the sampling action.

[0138] It is understood that when the fluid sampling device 100 includes the aforementioned first shut-off valve 1124, second shut-off valve 1125 and third shut-off valve 122, the aforementioned sampling action may also include: shutting off the third shut-off valve 122 and opening the first shut-off valve 1124 and the second shut-off valve 1125 before the control power assembly 130 is operated.

[0139] It is understood that the aforementioned sampling instruction may include a target number of samplings. Accordingly, after responding to the aforementioned sampling action, the fluid sampling device 100 may perform the sampling action according to the aforementioned target number of samplings. Alternatively, the aforementioned sampling instruction may include a sampling period, which is the time interval between two adjacent sampling actions. Accordingly, after responding to the aforementioned sampling action, the fluid sampling device 100 may perform the sampling action multiple times according to the aforementioned sampling period until a stop instruction is received. That is, the specific number of times the fluid sampling device 100 performs the sampling action after responding to the aforementioned sampling instruction can be set according to actual needs.

[0140] In summary, the control method of the fluid sampling device 100 provided in this embodiment can be used in any of the fluid sampling devices 100 proposed in the first aspect above, and can control the fluid sampling device 100 to respond to the sampling command to perform at least one of the aforementioned sampling actions. During the execution of the sampling action, the aforementioned sample inlet 1101 can reciprocate once between the aforementioned first depth position and the second depth position while the aforementioned power component 130 is in operation, thereby sucking in the fluid to be sampled 300' within a certain depth range in the aforementioned fluid channel 200', and making the fluid sample output by the sample outlet 1102 include the fluid to be sampled 300' at the aforementioned different depth positions. This can improve the representativeness of the fluid sample, reduce the difference between the concentration of the fluid sample and the concentration of the fluid to be sampled 300' in the fluid channel 200', provide a guarantee for the reliability of the sample analysis results, help improve the stability of production, and reduce the manpower consumption and execution cost of sampling operations, thereby improving the execution efficiency of sampling operations.

[0141] In some examples, the aforementioned step S801 includes:

[0142] When the sampling command is a periodic acquisition command, the fluid sampling device 100 is controlled to perform sampling actions multiple times at preset time intervals; or

[0143] When the sampling command is a continuous acquisition command, the fluid sampling device is controlled to continuously perform sampling actions more than 100 times; or

[0144] When the sampling command is a single acquisition command, the control fluid sampling device 100 performs a sampling action once.

[0145] Specifically, when the aforementioned sampling instruction is a periodic sampling instruction, the sampling instruction includes the aforementioned preset time interval, which is used to represent the interval between two consecutive sampling actions performed by the aforementioned fluid sampling device 100. Accordingly, when the fluid sampling device 100 responds to the aforementioned periodic collection instruction, it can perform the aforementioned sampling action multiple times according to the aforementioned preset time interval to achieve periodic collection of fluid samples.

[0146] Alternatively, in response to the aforementioned continuous collection command, the fluid sampling device 100 can immediately execute the next sampling action after each sampling action is completed, thereby achieving continuous collection of fluid samples.

[0147] Alternatively, in response to the aforementioned single sampling command, the fluid sampling device 100 may shut down after completing one sampling action to prepare for the next sampling command.

[0148] It is understandable that, based on the aforementioned settings of this technical solution, the fluid sampling device 100 can have multiple operating modes in practical applications, thereby improving the diversity of the sampling function of the fluid sampling device 100.

[0149] It is understood that the aforementioned preset time interval can be set according to actual needs, such as, but not limited to, 10s, 30s, 60s, 5min, 10min, etc. The aforementioned preset time interval refers to the interval between the completion time of the current sampling action and the start time of the next sampling action. Accordingly, the aforementioned preset interval is greater than 0.

[0150] In some examples, the sampling action also includes:

[0151] Adjust the output flow rate of the power unit 130 to the target sampling flow rate.

[0152] In this technical solution, during the aforementioned sampling action, the output flow rate of the power component 130 can also be adjusted so that the power component 130 outputs fluid samples according to the target sampling flow rate, which is beneficial to control the amount and speed of fluid sample collection.

[0153] It is understandable that the aforementioned target sampling flow rate can be selected based on actual needs, and no further restrictions are imposed here.

[0154] It is understood that the aforementioned power assembly 130 may include the aforementioned sampling pump, which may be a variable frequency sampling pump or a variable displacement pump.

[0155] In some examples, the aforementioned control methods also include:

[0156] In response to a cleaning command, the cleaning assembly 120 is controlled to operate so that the sampling channel is connected to the cleaning fluid.

[0157] Specifically, the aforementioned fluid sampling device 100 can also respond to the aforementioned cleaning command and control the operation of the cleaning component 120 so that the drive channel is connected to the aforementioned liquid supply device, so that the cleaning fluid output by the liquid supply device can flow into the aforementioned sampling channel through the cleaning component 120, thereby achieving flushing of the inside of the flow guiding component 110, which helps to reduce the risk of blockage of the flow guiding component 110.

[0158] It is understandable that the aforementioned cleaning instructions can be issued manually by the operators or automatically generated under certain conditions. In other words, there can be multiple ways and timing for the generation of cleaning instructions, which will not be limited here.

[0159] In some examples, when the cleaning device includes a liquid guide 121 and a third shut-off valve 122, the aforementioned step of controlling the cleaning assembly 120 to operate in response to a cleaning command to allow the sampling channel to access the cleaning fluid includes:

[0160] When the cleaning command is a sample flushing command, the third shut-off valve 122 and the first shut-off valve 1124 are opened, and the second shut-off valve 1125 is closed; or

[0161] When the cleaning command is a sample rinsing command, the power unit 130 is controlled to operate, the third shut-off valve 122 and the second shut-off valve 1125 are controlled to open, and the first shut-off valve 1124 is controlled to close.

[0162] Specifically, when the cleaning device includes a liquid guide tube 121 and a third shut-off valve 122, the aforementioned sampling assembly correspondingly includes the aforementioned first pipe fitting 111 and second pipe fitting 112. The aforementioned second pipe fitting 112 includes the aforementioned three-way pipe 1121, a first flow pipe 1122, a second flow pipe 1123, a first shut-off valve 1124, and a second shut-off valve 1125. In this case, if the portion of the flow guide assembly 110 located between the aforementioned first port and the aforementioned sample inlet 1101 is considered as the sample inlet region of the flow guide assembly 110, and the portion of the flow guide assembly 110 located between the aforementioned second port and the aforementioned sample outlet 1102 is considered as the sample outlet region of the flow guide assembly 110, then when the aforementioned first shut-off valve 1124 is open and the second shut-off valve 1125 is closed, the cleaning fluid output by the cleaning assembly 120 can flow through the aforementioned sample inlet region. Internally, this allows for backwashing of the aforementioned sample inlet section, improving the cleanliness of the flow path and reducing the likelihood of blockage. Correspondingly, when the first shut-off valve 1124 is closed and the second shut-off valve 1125 is open, the cleaning fluid output by the cleaning component 120 can flow through the interior of the aforementioned sample outlet section, thereby flushing the aforementioned sample outlet section and improving the cleanliness of the flow path, reducing the likelihood of blockage. Based on this, the fluid sampling device 100 can control the flow direction of the cleaning fluid output by the cleaning component after entering the sampling channel by adjusting the on / off states of the first shut-off valve 1124 and the second shut-off valve 1125, thereby controlling the cleaning area when cleaning the flow guide component 110, which helps ensure the cleaning effect of the cleaning component 120 on the flow guide component 110.

[0163] Accordingly, the aforementioned cleaning command may include the aforementioned sample inlet flushing command and the sample outlet flushing command; when the fluid sampling device 100 responds to the aforementioned sample inlet flushing command, it can control the third shut-off valve 122 and the first shut-off valve 1124 to open and control the second shut-off valve 1125 to close, thereby achieving backflushing of the aforementioned sample inlet section, so as to improve the flow path cleanliness of the aforementioned sample inlet section and reduce the probability of blockage in the sample inlet section; when the fluid sampling device 100 responds to the aforementioned sample outlet flushing command, it can control the third shut-off valve 122 and the first shut-off valve 1124 to open and control the second shut-off valve 1125 to close, thereby achieving flushing of the aforementioned sample outlet section, so as to improve the flow path cleanliness of the aforementioned sample outlet section and reduce the probability of blockage in the sample outlet section.

[0164] It is understood that "cleaning component 120 running" means that the cleaning component 120 is in the aforementioned output state; correspondingly, "cleaning component 120 shutting down" means that the cleaning component 120 is in the aforementioned stopped state.

[0165] For example, when the cleaning command is a sample flushing command, the second shut-off valve 1125 is first controlled to shut off, and then the third shut-off valve 122 and the first shut-off valve 1124 are controlled to open; or

[0166] When the cleaning command is a sample rinsing command, the first shut-off valve 1124 is first controlled to shut off, then the third shut-off valve 122 and the second shut-off valve 1125 are controlled to open, and the power unit 130 is controlled to run.

[0167] In some examples, the aforementioned control methods also include:

[0168] When the running time of the cleaning component 120 reaches the preset time, the cleaning component 120 is controlled to shut down.

[0169] Specifically, when the running time of the cleaning component 120 reaches the preset time, it indicates that the cleaning component 120 has supplied a certain amount of cleaning fluid into the sampling channel, thereby improving the cleanliness of the inside of the flow guide component 110. In this case, the cleaning component 120 can be controlled to close, so as to cut off the connection between the sampling channel and the aforementioned liquid supply component, thereby interrupting the access of the sampling channel to the cleaning fluid, which is beneficial to save cleaning fluid and facilitates the aforementioned fluid sampling device 100 to perform sampling operations.

[0170] It is understandable that the aforementioned preset duration can be set according to actual needs, such as, but not limited to, 1 minute, 5 minutes, 10 minutes, 15 minutes, or 30 minutes, etc.

[0171] like Figure 9 As shown, a computer-readable storage medium 901 is provided according to a third aspect of the present disclosure.
