Description

Technical Field

[0001] This invention relates to the field of water source protection, and specifically to an intelligent stratified water intake device and control method for water source protection. Background Technology

[0002] Currently, in order to monitor the water quality of water sources, it is necessary to regularly sample water at different depths in the water source area, analyze the sampled water, and ensure that purification strategies are implemented in a timely manner.

[0003] For example, the water source stratification water intake device proposed in publication number CN221445535U, although it can achieve stratified water intake, still has the following defects in use: 1. When the device samples water at different depths in the water source, it operates by extending the connecting rod into the water at different depths and opening the sampling bottle in sequence to sample the water. This method is relatively cumbersome, especially when there are many sampling points, resulting in low overall work efficiency. 2. The sampling bottle of this device is easily damaged by floating objects when collecting water underwater, which may cause leakage. When the operator lifts the connecting rod out of the water, the water sample collected in the damaged sampling bottle will be lost, which will cause the water sample collection at that depth to fail. This not only reduces the sampling efficiency, but may also lead to the loss of key water layer data, affecting the accuracy and reliability of subsequent water quality analysis. 3. When the device takes multiple samples, the operator needs to remove the full sampling bottle and reinstall the empty sampling bottle, and then put the connecting rod back into the water to take samples. The whole process is time-consuming and labor-intensive, and cannot achieve continuous automated sampling operations. It is difficult to meet the actual needs of batch sampling and long-term water sample collection in water source quality monitoring.

[0004] To this end, we propose an intelligent stratified water intake device and control method for water source protection. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent stratified water intake device and control method for water source protection, which solves the technical problems mentioned in the background.

[0006] The present invention achieves the above objectives through the following technical solutions: Intelligent stratified water intake devices for water source protection include: Guide frame; Several sets of connectors are vertically slidably disposed on each side wall of the guide frame. Each connector is equipped with a water intake component, and a locking part is provided inside the connector. A driving component, located inside the guide frame, is used to dock with any connecting component and drive it to move along the height direction of the guide frame to the desired position; The locking part is used to separate the connector from the guide frame when the connector and the drive component are docked, and to fix the connector to the guide frame when the connector and the drive component are separated.

[0007] A further improvement is that the guide frame includes a frame body, the outer wall of which has a guide opening communicating with its inner cavity, the connecting member includes a support frame slidably disposed in the guide opening, both sides of the support frame are provided with positioning protrusions for cooperating with the locking part, the positioning protrusions are fixed in the frame body and extend along the height direction of the frame body, the outer side of the support frame is provided with a connecting frame for connecting the water intake device, and the top of the support frame is connected to the top wall of the frame body through a reset elastic member, the reset elastic member is used to drive the support frame to reset upward to the initial position.

[0008] A further improvement is that the locking part includes a cavity opened in the support frame, a trapezoidal block is slidably arranged in the cavity, one end of the trapezoidal block is provided with a magnetic docking part that movably passes through the inner end of the support frame, the other end of the trapezoidal block is connected to the inner wall of the cavity through an elastic element, and a locking block is slidably abutted against the inclined surfaces on both sides of the trapezoidal block. The end of each locking block away from the trapezoidal block passes through the side wall of the support frame, and an elastic element is provided between the locking block and the inner wall of the cavity. Locking grooves for the locking blocks to be inserted are opened at intervals on the positioning protrusion.

[0009] A further improvement is that the driving component includes a telescopic device 1 located on the top wall of the frame, a rotating device 1 located at the output end of the telescopic device 1, and a docking block located at the output end of the rotating device 1. The docking block is located inside a plurality of connecting components. An electromagnetic component for attracting magnetic docking components is embedded on one side of the docking block. A positioning detection component for contacting the top of the support frame is provided on the docking block above the electromagnetic component. When the positioning detection component contacts the top of any support frame, the electromagnetic component corresponds to the magnetic docking component on that support frame, and the positioning detection component is electrically connected to the electromagnetic component and the telescopic device. When the electromagnetic component is energized and attracts the magnetic docking component, the trapezoidal block moves inward so that the locking block disengages from the locking groove.

[0010] A further improvement is that the water taking component includes a water taking bottle detachably mounted on the connecting frame. The top and bottom of the water taking bottle are respectively provided with an inlet pipe and an outlet pipe, and both the inlet pipe and the outlet pipe are provided with a solenoid valve. A float is movably mounted inside the water taking bottle. A detection sensor for cooperating with the float is provided on the top of the water taking bottle. A leak-proof protective component is provided on the outside of the water taking bottle. The inner wall of the cavity is also provided with an electromagnetic block for energizing and adsorbing the trapezoidal block to move inward. The detection sensor, electromagnetic block and electromagnetic valve are electrically connected. When the detection sensor detects that the float has moved upward to a preset position, it controls the electromagnetic block to be energized and the electromagnetic valve in the water inlet pipe to be closed. The top of the support frame is connected to the top wall of the frame through a reset elastic element. The reset elastic element is used to drive the support frame to reset upward to the initial position.

[0011] A further improvement is that the leak-proof protective component includes a housing located on the bottom wall of the connecting frame and fitted onto the outer wall of the water bottle. A sealing plate is provided at the top of the housing, and the sealing plate is movably fitted onto the outer wall of the water bottle. A movable ring, driven upwards by a float, is slidably disposed inside the water bottle to contact a detection sensor. When the detection sensor contacts the movable ring, it controls an electromagnetic block and a solenoid valve in the water inlet pipe. A pull rope is connected to the bottom of the movable ring, one end of which passes through the outer wall of the water bottle and is connected to a locking block. The locking block is embedded in the outer wall of the water bottle and connected to the outer wall of the water bottle via an elastic element. The sealing plate has a slot for inserting a locking block. When the movable ring moves upward, the locking block is pulled out of the slot by the pull rope. From the inside to the outside, the sealing plate and the housing are provided with a leak-proof telescopic soft tube and an elastic connector. The elastic connector is used to drive the sealing plate upward to contact the top wall of the connecting frame when the locking block is disengaged from the slot, so that the leak-proof telescopic soft tube is covered on the outside of the water bottle. A liquid detection sensor and a drain pipe are provided on the bottom wall of the housing between the leak-proof telescopic soft tube and the water bottle. The liquid detection sensor is electrically connected to an external alarm, and the drain pipe has a solenoid valve.

[0012] A further improvement is that the device also includes a sample buffer mounted on the frame; The support frame includes a movable part fixed to the connecting frame. A fixed part is movably sleeved on the outside of the movable part. An elastic element is provided between the movable part and the fixed part. A wedge-shaped frame is provided on the outer wall of the connecting frame. A contact rod is provided on the upper part of the outer wall of the frame for cooperating with the wedge-shaped frame. The contact rod is used to cooperate with the wedge-shaped frame when the support frame is reset upward to the initial position to drive the connecting frame to move outward to a preset position to cooperate with the sample buffer.

[0013] A further improvement is that the sample buffer includes a mounting bracket fixed to the top of the frame and a frame-type shielding bracket sleeved on the outside of the frame and connected to the mounting bracket. A frame-type support frame is fixedly connected below the shielding bracket at intervals. A liquid inlet is opened on the shielding bracket at the position corresponding to the water taking part. Each liquid inlet is closed by a movable cover plate that is elastically slidably set on the shielding bracket. A linear guide rail assembly is provided on the support frame at the position corresponding to the water taking part. A placement seat is slidably provided on the linear guide rail assembly. Several sets of liquid receiving boxes are provided on the placement seat. The placement seat is driven to move by the linear guide rail assembly so that a liquid receiving box corresponds to the liquid inlet. When the connecting frame moves outward to the preset position, the movable cover is driven by the connecting frame to open the liquid inlet. After the connecting frame moves outward to the preset position, the water outlet pipe and the drain pipe on the connecting frame are both located above the liquid inlet.

[0014] A further improvement is that the device also includes a reset component, which includes a rotating frame rotatably sleeved on the outer wall of the mounting frame, and a second rotating device on the mounting frame for driving the rotating frame to rotate. A top rod is movably inserted into the rotating frame, and the top rod is driven to rise and fall by the second telescopic device on the rotating frame. The connecting frame is provided with an movable opening for the top rod to pass through. The top rod is used to correspond to the movable opening when the connecting frame moves outward to a preset position, so as to push the sealing plate downward through the movable opening and contact the housing by the telescopic device.

[0015] An intelligent stratified water intake control method for water source protection, utilizing the aforementioned device, includes the following steps: S1: Vertically and securely install the guide frame within the target water area of ​​the water source; S2: Control the drive unit to move along the guide frame to the position of the target connector and dock with the target connector. Then, the locking part inside the connector releases its fixation to the guide frame. Subsequently, the drive unit drives the connector to slide downward until the water taking part on the connector reaches the preset target water taking depth. When the water taking part reaches the target water taking depth, the drive unit separates from the connector, and the locking part on the connector fixes the connector to the guide frame. S3: Following the method in step S2, make the water intake components on the remaining connectors reach the preset target water intake depth respectively; S4: Water is taken out through the water taking component. After water is taken out, the driving component can connect with each connecting component in sequence and drive the connecting component to slide upward along the guide frame to the initial position, thereby lifting each water taking component out of the water surface.

[0016] The beneficial effects of this invention are as follows: 1) This invention sets a single driving component to selectively dock with any connecting component, and drives the connecting component to move along the guide frame to the target water intake depth and then fixes it stably by locking part, so that each water intake component can be independently adjusted to the required different depth positions, realizing flexible setting and accurate positioning of multi-water layer water intake positions, which is convenient to operate and shortens the overall water intake operation time. 2) After the water bottle takes water, it can automatically return to the surface above the water, reducing the time the water bottle stays in the water and lowering the probability of the water bottle being damaged by floating objects in the water. In addition, during the process of the water bottle completing water taking and returning to the surface, the leak-proof telescopic soft cylinder automatically unfolds and covers the outside of the water bottle, ensuring that even if the water bottle is accidentally damaged, a certain amount of target water layer water can still be retained for subsequent detection and analysis, avoiding the loss of key water layer data and improving the fault tolerance of water taking operation and the reliability of data acquisition. 3) After the water bottle completes water collection and rises to its reset position, the connecting frame automatically moves outward with the cooperation of the wedge frame and the contact rod, aligning the water outlet pipe and the drain pipe with the liquid inlet of the sample buffer. This automatically transfers the water in the water bottle to the receiving box for collection and storage. At this point, the water bottle can enter the next water collection process without the need for manual replacement of each water bottle. This achieves continuous and automated multi-round water collection operations, fully meeting the practical needs of batch sampling and long-term water sample collection in water source quality monitoring.

Detailed Implementation

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] Please see the appendix Figure 1-3 An intelligent stratified water intake device for water source protection includes: The guide frame 100 in this embodiment is preferably rectangular in cross-section and can be made of stainless steel. Its bottom can be provided with a base and anchoring components (not shown in the figure) to fix it in the target water area of ​​the water source to ensure the overall stability of the device. Several sets of connectors 200 are vertically slidably disposed on each side wall of the guide frame 100. For example, if the guide frame 100 is rectangular, then in this embodiment, there are four sets of connectors 200. Each connector 200 is provided with a water-taking component 300. The connector 200 is provided with a locking part. Each set of connectors 200 is initially located in the upper position of the guide frame 100, so that the water-taking component 300 is above the water surface when not in operation. A driving component 400 is located inside the guide frame 100 and is used to dock with any connecting component 200 and drive it to move along the height direction of the guide frame 100 to the desired position. In this way, the depth of each water intake component 300 in the target water area can be adjusted to achieve stratified water intake. The locking part is used to separate the connector 200 from the guide frame 100 when the connector 200 is docked with the drive member 400, so that the drive member 400 can drive the connector 200 to move along the height direction of the guide frame 100, and to fix the connector 200 to the guide frame 100 when the connector 200 is separated from the drive member 400, so that the connector 200 will not move.

[0022] Please see the appendix Figure 1-4 Preferably, the guide frame 100 of this embodiment includes a hollow frame 101. The outer wall of the frame 101 has a vertical guide opening 102 communicating with its inner cavity. The connector 200 includes a support frame slidably disposed in the guide opening 102. Preferably, a guide rod can be provided in the vertical guide opening 102 of this embodiment. The guide rod moves through the support frame to ensure the stable lifting and lowering of the support frame. Positioning protrusions 103 for cooperating with the locking part are provided on both sides of the support frame. The height of the positioning protrusions 103 is the same as the height of the vertical guide opening 102. The positioning protrusions 103 are fixed inside the frame 101. Extending along the height of the frame 101, the outer side of the support frame is provided with a connecting frame 201 for connecting the water intake component 300. In this embodiment, the vertical cross-section of the connecting frame 201 is U-shaped. Optionally, in this embodiment, in actual practice, a flexible waterproof structure that seals the guide opening 102 can be provided on the outer wall of the frame 101. For example, a roller shutter component can be provided at the upper and lower ends of the guide opening 102, and the opposite ends of the two sets of roller shutter components can be connected to the support frame to reduce the entry of debris in the water into the frame 101 without interfering with the movement of the support frame. Of course, it is not limited to the above method, and will not be described in detail here.

[0023] Please see the appendix Figure 3-4Preferably, the locking part of this embodiment includes a cavity formed within the support frame. A trapezoidal block 205 is slidably disposed within the cavity. The trapezoidal block 205 can move within the cavity along the length direction of the support frame. The area of ​​the end face of the trapezoidal block 205 facing the driving member 400 is larger than the area of ​​its other end face, that is, the larger end of the trapezoidal block 205 faces the direction of the driving member 400. One end of the trapezoidal block 205 is provided with a magnetic coupling member 207 that movably penetrates the inner end of the support frame. The magnetic coupling member 207 is T-shaped, and its rod movably penetrates the inner side of the support frame and extends into the inner cavity of the frame 101. The end of the magnetic coupling member 207 located in the inner cavity of the frame 101 is a magnetic head, made of a permanent magnet or a magnetically attractable metal material, used to engage with the driving member 400. The trapezoidal block 205 is connected to the inner wall of the cavity through an elastic element (such as a spring). Both sides of the trapezoidal block 205 slide against a locking block 206 (the contact end between the locking block 206 and the slope of the trapezoidal block 205 is embedded with a freely rotating ball). The end of each locking block 206 away from the trapezoidal block 205 passes through the side wall of the support frame. That is, the two sets of locking blocks 206 correspond to the two positioning protrusions 103 respectively. An elastic element (such as a spring) is provided between the locking block 206 and the inner wall of the cavity. When the magnetic docking component 207 moves towards the driving component 400, the elastic element causes the locking block 206 to move into the cavity. The positioning protrusions 103 are provided with locking grooves for the locking blocks 206 to be inserted.

[0024] Please see the appendix Figure 3-4 Preferably, the driving component 400 in this embodiment includes a telescopic device 401 (preferably an electric push rod or hydraulic cylinder) disposed on the top wall of the frame 101, a rotating device 402 (preferably a stepper motor or servo motor) disposed at the output end of the telescopic device 401, and a docking block 403 disposed at the output end of the rotating device 402. The docking block 403 is located inside a plurality of connecting components 200. An electromagnetic component (preferably an electromagnet) is embedded on one side of the docking block 403 for attracting magnetic docking components 207 when energized. In use, the rotating device 402 drives the docking block 403 to rotate a preset position. The angle is adjusted so that the electromagnetic component is aligned with the magnetic docking component 207 on the target connector 200 to be docked. Then, the docking block 403 is driven to rise and fall to the position of the connector 200 by the telescopic device 401. The docking block 403 above the electromagnetic component is provided with a positioning detection component 404 for contacting the top of the support frame. In this embodiment, the positioning detection component 404 preferably includes a support plate fixed above the docking block 403 and a sensor embedded in the support plate. The sensor can be a pressure sensor or a proximity switch. When the support plate moves with the docking block 403 and contacts the top of the target support frame, the sensor is pressed or sensed and sends a positioning signal. When the positioning detection component 404 contacts the top of any support frame, the electromagnetic component corresponds to the magnetic docking component 207 on that support frame, and the positioning detection component 404 is electrically connected to the electromagnetic component and the telescopic device 401. Specifically, in this embodiment, the positioning detection component 404, the electromagnetic component, and the telescopic device 401 are all electrically connected to the controller. When the sensor in the positioning detection component 404 contacts the support frame, it sends a signal to the controller, which then controls the telescopic device 401 to stop lifting and lowering, and energizes the electromagnetic component. When the electromagnetic component is energized and attracts the magnetic docking component 207, the trapezoidal block 205 moves inward so that the locking block 206 disengages from the locking groove. Optionally, in this embodiment, a slot can be opened on the side of the docking block 403 where the electromagnetic component is embedded, and an insertion block corresponding to the slot can be provided at the inner end of the magnetic docking component 207. When the electromagnetic component and the magnetic docking component 207 attract each other, the insertion block enters the slot to improve the docking strength between the two.

[0025] It should be noted that after all the connectors 200 are adjusted to the required positions by the drive unit 400, the docking block 403 can be controlled to move upward to the initial position by the telescopic device 401. The initial position of the docking block 403 is located above the initial position of the connectors 200, so that the subsequent upward reset of the connectors 200 will not be interfered with by the docking block 403 and its positioning detection unit 404.

[0026] An intelligent stratified water intake control method for water source protection, utilizing the aforementioned device, includes the following steps: S1: Vertically and securely install the guide frame 100 within the target water area of ​​the water source; S2: Control the drive unit 400 to move along the guide frame 100 to the position of the target connector 200 and dock with the target connector 200. Then, the locking part inside the connector 200 releases its fixation to the guide frame 100. Subsequently, the drive unit 400 drives the connector 200 to slide downward until the water taking part 300 on the connector 200 reaches the preset target water taking depth. When the water taking part 300 reaches the target water taking depth, the drive unit 400 separates from the connector 200, and the locking part on the connector 200 fixes the connector 200 to the guide frame 100. S3: Following the method of step S2, make the water intake components 300 on the remaining connectors 200 reach the preset target water intake depth respectively; S4: Water is taken out through the water taking part 300. After taking out water, the driving part 400 can be connected to each connecting part 200 in sequence and drive the connecting part 200 to slide upward along the guide frame 100 to the initial position, so that each water taking part 300 can be lifted out of the water surface.

[0027] Example 2

[0028] Please see the appendix Figure 3-6Based on Embodiment 1, the water-collecting component 300 in this embodiment includes a water-collecting bottle 301 detachably mounted on the connecting frame 201. The top and bottom of the water-collecting bottle 301 are respectively provided with an inlet pipe 303 and an outlet pipe 302, and both the inlet pipe 303 and the outlet pipe 302 are provided with solenoid valves. The solenoid valves are preferably waterproof normally closed solenoid valves. A float 304 is movably mounted inside the water-collecting bottle 301. In this embodiment, a guide rod can be vertically mounted inside the water-collecting bottle 301, and a float is slidably mounted on the guide rod. The float 304 is preferably a lightweight float with a diameter smaller than the inner diameter of the water-collecting bottle 301, for example, made of closed-cell foam plastic or hollow plastic, which can float smoothly along the guide rod as the water level in the water-collecting bottle 301 rises. A detection sensor 306 is provided at the top of the water-collecting bottle 301 for cooperating with the float 304, and a leak-proof protection component 500 is provided on the outside of the water-collecting bottle 301. The inner wall of the support frame cavity is also provided with an electromagnetic block 208 for energizing and adsorbing the trapezoidal block 205 to move inward. The detection sensor 306, the electromagnetic block 208 and the solenoid valve are electrically connected. That is, in this embodiment, the detection sensor 306, the electromagnetic block 208 and the solenoid valve are all electrically connected to the controller. When the detection sensor 306 detects that the float 304 has moved upward to the preset position, it sends a signal to the controller. The controller controls the electromagnetic block 208 to be energized and the solenoid valve in the water inlet pipe 303 to be closed. When the trapezoidal block 205 moves inward, the locking block 206 disengages from the locking groove. The top of the support frame is connected to the top wall of the frame 101 through a reset elastic member 209 (for example, the reset elastic member 209 is preferably a tension spring). The reset elastic member 209 is used to drive the support frame to reset upward to the initial position. During water intake, the controller opens the solenoid valve in the inlet pipe 303, allowing water from the target water layer to enter the water intake bottle 301 under water pressure. The float 304 inside the water intake bottle 301 rises with the water level. When the float 304 reaches the height of the detection sensor 306, the sensor sends a signal to the controller. The controller then closes the solenoid valve in the inlet pipe 303 to prevent further water intake. Simultaneously, it energizes the electromagnetic block 208 in the connector 200, causing the trapezoidal block 205 to move inwards, thereby retracting the locking block 206 and disengaging it from the locking groove. The connector 200... When the guide frame 100 is released from lock, the support frame, under the action of the reset elastic element 209, drives the water bottle 301 to automatically slide upward along the guide frame 100 to reset to the initial position. Even if the water bottle 301 rises above the water surface, the automatic water intake and recovery of a single water layer is completed. The above method has the following advantages: after water intake is completed, it automatically unlocks and relies on the reset elastic element 209 to achieve lifting and reset. There is no need to wait for all water intake components 300 to complete water intake before the drive component 400 recovers them one by one. This reduces the residence time of the water bottle 301 in the water and reduces the probability of the water bottle 301 being damaged by collision with floating objects in the water.

[0029] Example 3

[0030] Please see the appendix Figure 4-6 Based on Embodiment 2, the leak-proof protective component 500 in this embodiment includes a housing 501 disposed on the bottom wall of the connecting frame 201 and sleeved on the bottom of the outer wall of the water bottle 301. In this embodiment, the housing 501 has an annular cross-section and an open top. A sealing plate 502 is provided on the top of the housing 501. The sealing plate 502 is movably sleeved on the outer wall of the water bottle 301. The sealing plate 502 can slide up and down along the outer wall of the water bottle 301. An elastic sealing ring is provided between the sealing plate 502 and the outer wall of the water bottle 301 to achieve sliding sealing. A movable ring 305 is slidably disposed inside the water bottle 301, driven upward by the float 304 to contact the detection sensor 306. Initially, 305 is located inside the water bottle 301 and below the detection sensor 306. When the detection sensor 306 contacts the movable ring 305, it controls the solenoid block 208 and the solenoid valve in the water inlet pipe 303. Specifically, in this embodiment, the detection sensor 306 can be a contact sensor or the like. When the float 304 moves upward, it will contact the movable ring 305. Then, the float 304 will cause the movable ring 305 to move upward and contact the detection sensor 306. When the two are in contact, it means that the float 304 has reached the preset position. At this time, the detection sensor 306 controls the solenoid block 208 to be energized and the solenoid valve in the water inlet pipe 303 to be closed. A pull cord 503 is connected to the bottom of the movable ring 305. One end of the pull cord 503 passes through the outer wall of the water bottle 301 and is connected to a locking block 504. In this embodiment, the outer end of the locking block 504 is arc-shaped. The locking block 504 is embedded in the outer wall of the water bottle 301 and connected to the outer wall of the water bottle 301 by an elastic element (e.g., a spring). Preferably, the vertical section of the locking block 504 is T-shaped. A T-shaped groove that mates with the locking block 504 is opened on the outer wall of the water bottle 301. One end of the elastic element is connected to the locking block 504, and the other end is connected to the bottom of the T-shaped groove. The sealing plate 502 is provided with a locking groove (arc-shaped) for the locking block 504 to be inserted. Preferably, in this embodiment... In this embodiment, a protrusion is integrally provided at the bottom of the sealing plate 502, and a slot is provided on the protrusion. When the movable ring 305 moves upward, the pull rope 503 pulls the locking block 504 out of the slot. A leak-proof telescopic soft tube 505 and an elastic connector 506 are provided sequentially from the inside to the outside between the sealing plate 502 and the housing 501. In this embodiment, the leak-proof telescopic soft tube 505 is, for example, a waterproof corrugated telescopic sleeve or a waterproof multi-level nested telescopic sleeve, etc. Its upper and lower ends are respectively sealed and connected to the bottom of the sealing plate 502 and the bottom wall of the housing 501. The elastic connector 506 is, for example, a spring, whose upper and lower ends are respectively connected to the bottom of the sealing plate 502 and the bottom wall of the housing 501. The elastic connector 506 is used to drive the sealing plate 502 upward to contact the top wall of the connecting frame 201 when the locking block 504 disengages from the slot, so as to cover the outside of the water bottle 301 with the leak-proof telescopic flexible cylinder 505. In this embodiment, the bottom wall of the water bottle 301 is connected to the bottom wall of the connecting frame 201, and its top moves through the top of the connecting frame 201 and is flush with the top of the connecting frame 201. After the locking block 504 disengages from the slot, the elastic connector 506 drives the sealing plate 502 upward, thereby causing the leak-proof telescopic flexible cylinder 505 to rise. When the sealing plate 502 contacts the top wall of the connecting frame 201, the outer wall of the water bottle 301 is completely covered. An anti-leak telescopic flexible cylinder 505 is installed inside to form a closed protective cavity surrounding the water bottle 301. This method has the following advantages: when the water bottle 301 is about to finish taking water and rises, the anti-leak telescopic flexible cylinder 505 automatically unfolds and covers the outside of the water bottle 301. Even if the water bottle 301 is damaged and leaks due to collision with floating objects in the water, the leaked water is still trapped between the anti-leak telescopic flexible cylinder 505 and the water bottle 301, and will not flow directly back to the water area, causing water loss or insufficient water intake. This ensures that even in the event of an accidental leak, a certain amount of target water layer water can still be collected for testing and analysis. A liquid detection sensor 507 and a drain pipe are installed on the bottom wall of the housing 501, located between the leak-proof telescopic flexible cylinder 505 and the water bottle 301. The liquid detection sensor 507 is electrically connected to an external alarm, and the drain pipe contains a solenoid valve. In this embodiment, the liquid detection sensor 507, the external alarm, and the solenoid valve are all electrically connected to a controller. When the liquid detection sensor 507 detects liquid, it indicates that the water bottle 301 is leaking. At this time, it sends a signal to the controller, which controls the external alarm to remind the operator, so that the operator can deal with the situation in a timely manner. After water collection is completed, the solenoid valves of the water outlet pipe 302 and the drain pipe can be opened simultaneously by the controller to collect the water in the water bottle 301 and the water that has leaked between the leak-proof telescopic flexible cylinder 505 and the water bottle 301.

[0031] Example 4

[0032] Please see the appendix Figure 7-8 Based on embodiment 3, the device in this embodiment also includes a sample buffer 600 disposed on the frame 101. When the guide frame 100 is installed in the target water area of ​​the water source, the sample buffer 600 is located above the water surface. The support frame includes a movable part 204 fixed to the connecting frame 201. A fixed part 202 is movably sleeved on the outside of the movable part 204. The movable part 204 can slide horizontally relative to the fixed part 202. Specifically, the aforementioned cavity, trapezoidal block 205, locking block 206 and other structures are all installed in the fixed part 202, which will not be described in detail here. An elastic element four is provided between the movable part 204 and the fixed part 202. The elastic element four is preferably a spring. A wedge-shaped frame 203 is provided on the outer wall of the connecting frame 201. The vertical section of the wedge-shaped frame 203 is a right trapezoid or a right triangle. The bottom end of its inclined surface is located inside its top end. A contact rod 104 for cooperating with the wedge-shaped frame 203 is provided on the upper part of the outer wall of the frame 101. The contact rod 104 is horizontally arranged. The outer end of the contact rod 104 is embedded with a ball or provided with a roller so as to cooperate with the inclined surface of the wedge-shaped frame 203. The contact rod 104 is used to cooperate with the wedge frame 203 when the support frame is reset upward to the initial position to drive the connecting frame 201 to move outward to a preset position to cooperate with the sample buffer 600. Specifically, under the action of the reset elastic member 209, the support frame drives the connecting frame 201 and the water bottle 301 to reset upward to the initial position. At the end of the reset stroke, the inclined surface of the wedge frame 203 on the connecting frame 201 meets the outer end of the contact rod 104 on the frame 101. The contact rod 104 generates an outward pushing force on the wedge frame 203, pushing the connecting frame 201 together with the movable part 204 to move outward. When the support frame is fully reset to the initial position, the connecting frame 201 is pushed to the preset position. At this time, the water bottle 301 is just aligned with the sample buffer 600 so that the water in the water bottle 301 can be transferred to the sample buffer 600 for temporary storage.

[0033] Preferably, the sample buffer 600 in this embodiment includes a mounting bracket 601 fixed to the top of the frame 101, and a frame-shaped shielding bracket 602 sleeved on the outside of the frame 101 and connected to the mounting bracket 601 via a bracket. A frame-shaped support bracket 608 is fixedly connected below the shielding bracket 602 via bracket spacing. Both the connecting member 200 and the water-taking member 300 can pass upward through the shielding bracket 602 and the support bracket 608. A liquid inlet 607 is provided on the shielding bracket 602 at a position corresponding to the water-taking member 300. When the connecting bracket 201 is pushed to a preset position, the liquid inlet 607 is aligned with the water outlet pipe 302 and the drain pipe. The number of liquid inlets 607 is the same as the number of water-taking members 300, as shown in the attached figure. Figure 1-2 and attached Figure 7-8As shown, the water intake component 300 is provided with four sets, and the liquid inlet 607 on the shielding frame 602 is also provided with four sets. Each liquid inlet 607 is closed by a movable cover plate 606 that is elastically slidably provided on the shielding frame 602. In this embodiment, the movable cover plate 606 has an L-shaped vertical section. Its horizontal section is used to cover the liquid inlet 607, and its vertical section serves as a driving arm that contacts the connecting frame 201. The movable cover plate 606 is slidably installed on the shielding frame 602 through a slider and a sliding groove, and is connected to the shielding frame 602 through a spring. In its natural state, the spring pulls the movable cover plate 606 to close the liquid inlet 607. Linear guide rail assemblies 603 are provided on the support frame 608 at positions corresponding to the water intake component 300. The linear guide rail assemblies 603 are preferably miniature electric linear guide rails. Placement seats 604 are slidably provided on the linear guide rail assemblies 603. The placement seats 604 are connected to the sliders in the linear guide rail assemblies 603. Several sets of liquid receiving boxes 605 are provided on the placement seats 604. The top of the liquid receiving boxes 605 is hollow. The number of them can be set according to actual needs. The placement seats 604 are driven to move by the linear guide rail assemblies 603 so that one liquid receiving box 605 corresponds to the liquid inlet 607. By controlling the movement of the placement seats 604 through the linear guide rail assemblies 603, different liquid receiving boxes 605 can be aligned with the liquid inlet 607 above in sequence. The tops of the remaining liquid receiving boxes 605 are covered by the shielding frame 602 to prevent external debris from falling in. When the connecting frame 201 moves outward to a preset position, the movable cover 606 is driven by the connecting frame 201 to move and open the liquid inlet 607 (that is, when the connecting frame 201 moves outward in cooperation with the wedge frame 203 and the contact rod 104, it will contact the vertical section of the movable cover 606, and drive the movable cover 606 to slide to open the liquid inlet 607 during its movement). After the connecting frame 201 moves outward to the preset position, the water outlet pipe 302 and the drain pipe on the connecting frame 201 are both located above the liquid inlet 607. Optionally, a sensor can be set on the shielding frame 602 near the liquid inlet 607. When the sensor detects that the connecting frame 201 has moved to the preset position, it can send a signal to the controller, so that the controller controls the solenoid valves in the water outlet pipe 302 and the drain pipe on the connecting frame 201 to open and discharge the water in the water bottle 301. This will not be described in detail here.

[0034] Preferably, the device in this embodiment further includes a reset member 700, which includes a rotating frame 702 rotatably mounted on the outer wall of the mounting frame 601 via a bearing, and a second rotating device 701 mounted on the mounting frame 601 for driving the rotating frame 702 to rotate. The second rotating device 701 includes, for example, a stepper motor or a servo motor. The second rotating device 701 can be connected to the rotating frame 702 through a gear and a gear ring. A push rod 703 is movably inserted on the rotating frame 702. The push rod 703 is driven to rise and fall by a second telescopic device 704 (such as an electric telescopic rod or a hydraulic cylinder) mounted on the rotating frame 702. The connecting frame 201 is provided with an opening for the push rod 703 to pass through. The push rod 703 is used to align with the movable opening when the connecting frame 201 moves outward to a preset position. It is driven downward through the movable opening by the telescopic device 704 to push the sealing plate 502 downward to contact the housing 501. In order to facilitate the downward reset of the sealing plate 502, after the water in the water bottle 301 and the leak-proof telescopic soft tube 505 is discharged into the liquid receiving box 605, the push rod 703 can be driven downward by the telescopic device 704. The push rod 703 passes through the movable opening to make the sealing plate 502 downward. When the sealing plate 502 is in contact with the housing 501, the locking block 504 re-enters the locking groove to fix the sealing plate 502. The rotating frame 702 can be rotated by the rotating device 701, so that the push rod 703 can cooperate with the water taking part 300 at different positions.
