Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil sampling, more particularly, it relates to a water quality oil sampler and a use method thereof. BACKGROUND

[0002] With the extensive use of oil, water surface oil pollution, especially waterway oil pollution, is becoming increasingly serious, and the demand for detection of oil pollutants in river water samples is increasing. The existing detection method generally collects water samples in the river channel through a sampler and then sends them to a laboratory for detection. During the oil pollution process, an oil film is formed on the water surface. At room temperature, the oil film is in a liquid state, so the sampler can be directly sent underwater for sampling.

[0003] After the rubber base is placed in the water with the support, its elasticity significantly decreases due to the low temperature environment. When the sampling bottle is docked with the rubber base, it cannot be tightly attached as at normal temperature. During the subsequent storage and transportation of the water sample, a small gap may cause water leakage due to external forces such as shaking and jolting. When the temperature is low, an oil film with solid film properties is formed above the water surface due to low temperature. The sampling bottle contacts the oil film during the downward movement path, and the oil film adheres to the edge of the sampling bottle mouth, forming irregular protrusions. This causes the oil film to fill the sealing gap between the rubber base and the sampling bottle when the sampling bottle is docked with the rubber base, which cannot be tightly attached, resulting in a small gap that is not tightly sealed. During the subsequent storage and transportation of the water sample, water leakage occurs, affecting the integrity of the sample and the accuracy of the detection results. SUMMARY

[0013] As a further optimization scheme of the present application, the electric telescopic rod is fixedly installed in the middle of the stand, the driving end of the electric telescopic rod is fixedly connected with the top of the adapter module, the bottle opening outer wall of the sampling bottle is threadedly connected with the bottom of the adapter module, the rubber base is clamped on the top of the stand, the pressing plates on both sides are rotatably connected with the top of the stand and cover the outer wall top of the rubber base, the control switch is fixedly installed on the top of the stand, and the control switch is electrically connected with the electric telescopic rod and the infrared sensor.

[0014] As a further optimization scheme of the present application, a method for using a water quality oil sampler is applied to a water quality oil sampler, comprising the following steps: Step 1: Place the rubber base on the top of the stand and directly below the sampling bottle, and rotate the two side pressing plates to cover the outer wall top of the rubber base to complete the fixation, then place the stand into the water sampling area, and rotate the sampling bottle into the bottom of the adapter module, drive the sampling bottle to move downward along the outer wall of the stand through the electric telescopic rod, penetrate the water column into the inside of the sampling bottle through the liquid surface, and seal the water sample by connecting with the rubber base during the continuous downward movement; Step 2: As the water sample collection moves downward, the bottom of the two side adapter plates expands outward under the downward force of the adapter module, further driving the extension sleeve plate to move outward along the inner wall of the cavity, and the horizontal displacement is transmitted to the transmission rod to form rotary transmission through the adapter rack and the transmission gear; During the downward movement of the sampling bottle driven by the electric telescopic rod, the two side connecting plates rotate downward under the rotary transmission of the transmission rod corresponding to the movement direction of the sampling bottle, and drive the dynamic plate to move to the position of the rubber base under the cooperation of the hollow frame and the lifting column, the bottle opening outer wall is in extrusion contact with the top of each fan-shaped plate during the downward movement of the sampling bottle, and the adhered solidified oil film is peeled off; With the butt joint of the sampling bottle and the rubber base in place, the arc-shaped plates on both sides are rotated from the original position to the symmetrical position under the action of the rotary transmission force, and after passing through the internal broken infrared sensor downwardly emitted infrared, the electric heating wire module arranged inside the arc-shaped plate starts to operate, and after the switching of the arc-shaped plates on both sides is completed, heat transfer is carried out on the rubber base and the bottle mouth of the sampling bottle, which assists the rubber base to restore elasticity and melts the residual solid oil film at the bottle mouth of the sampling bottle, so as to eliminate the gap existing when the two are connected and ensure the tightness of the connection. Step 3: After the sampling bottle is butt jointed with the rubber base, the sealing of the water sample collection is completed, and then the reverse rotation drives the two side pressing tablets to remove the limitation on the rubber base, and the electric telescopic rod is reversely driven, so that the sampling bottle and the rubber base move upward and pass through the center through hole of the dynamic plate to reset. With the movement of the sampling bottle, the connection module moves the two side extension sleeves to the inner wall of the cavity through the two side connection support plates, and the reverse transmission is formed through the connection rack and the transmission gear, so that the dynamic plate moves upward synchronously. The sampling bottle and the rubber base containing the collected water sample form a support below. In this process, the reverse transmission force also acts on the two arc-shaped plates. When the collected water sample is moved to reset with the electric telescopic rod, the two arc-shaped plates also penetrate the inside of the two sides again, and the infrared pipeline generated by the broken infrared sensor is broken again. The electric heating wire in the arc-shaped plate is stopped by the control switch triggered by the electric signal. Finally, the rotating movement is moved to the initial position, the marking ball rod is in contact with the marking ball rod and is deformed by extruding the compensation spring, so that the marking ball rod is in a pop-out state, and the marking ball rod is in a pop-out state. The water sample collection is completed. Step 4: Reverse rotation of the sampling bottle separates it from the bottom of the connection module, and the sealing cover is rotated and tightened on the upper end of the bottle mouth, so that the next step of water quality oil analysis determination can be directly transported.

[0015] The beneficial effects of the present application are: 1. The water quality oil sampler disclosed by the present application cooperates with the sampling bottle to cut off the water column downwardly to carry out the water sample collection process, the connection module generates downward extrusion force on the two side connection support plates, and the bottom end of the two side connection support plates acts on the extension sleeve to generate outward moving thrust, which forms a triangular support on the two sides of the stand to ensure the stability of the sampling process, and converts the displacement of the sampling path to horizontal displacement, so that the sealing process of the water sample collection triggers the arc-shaped block integrated with the electric heating wire inside to form position switching, to transfer heat to the rubber base to restore its flexibility, to compensate the hardening effect of low temperature on the rubber, to ensure the tightness of the sealing surface, to eliminate the small gap caused by insufficient elasticity, to avoid water sample leakage, and to make the rubber base and the bottle mouth of the sampling bottle expand slightly synchronously when heated, to extrude the gap filled with oil film by using the thermal expansion property of the rubber, so that even if there is residual oil film, the pressure generated by thermal expansion can extrude the oil film, to strengthen the sealing effect and reduce the risk of leakage.

[0016] 2, The water quality oil sampler, after water sampling is completed, the sampling bottle and the rubber base are driven to move upwards and are separated from the sampling water area, the extension sleeve plate is reversely moved according to the corresponding force, the reverse rotation of the arc-shaped plate is triggered, after the water sample is collected and moved to the position, the arc-shaped plate is also rotated and reset to the initial position, and in the rotating process, the marking ball rod is contacted, extrusion force is generated on the compensation spring to generate deformation, the marking ball rod is popped out to the outside of the connecting support plate, the whole water sample collection process is indicated to be completed, and when the position of the heat conduction arc-shaped block of the rubber base is rotated and switched next time, the extrusion force on the marking ball rod is eliminated, and under the action of the elastic potential energy accumulated by the deformation of the compensation spring, the marking ball rod is reset and stored in the inside of the connecting support plate, improper operation of an operator when sampling is not completed, such as moving the sampler in advance, disassembling the sampling bottle and the like, is effectively avoided, the standardization of the sampling process and the accuracy of the sampling result are ensured, and problems, such as water sample leakage, pollution or collection failure caused by misoperation are prevented.

[0017] 3, The water quality oil sampler, during the process that the water sample is collected and cut off, the positive and negative rotating forces are alternately transmitted, when the sampling bottle moves downwards, the dynamic plate moves downwards under the action of the positive rotating force, before the sampling bottle is docked with the rubber base, the bottle opening is gradually extruded and contacted with the fan-shaped plate of the dynamic plate, the continuous downward pressure is used to scrape off the solidified oil film layer by layer, then the docking and sealing are performed and the heat conduction treatment of the connecting area is cooperated, the temperature drop of the water sample caused by the low temperature of the environment is compensated, the detection method sensitive to the temperature of the water sample is adapted, the subsequent detection error caused by too low temperature is avoided, the low-temperature stratification or crystallization of the oil substances in the water sample is slowed down, the uniformity of the water sample composition during detection is ensured, and correspondingly, when the water sample is transmitted upwards and reset, the sampling bottle and the rubber base penetrate the through hole in the middle of the dynamic plate, and under the action of the reverse rotating force, the bottom of the sampling bottle is synchronously moved for a distance to form bottom receiving protection, and the heat conduction compensation and the physical protection mode are switched according to the process requirement.

[0032] As Figures 1-7 shown, the bistate compensation trigger module 8 further includes: A pair of engagement racks 804 are fixedly connected to the top of the two side extension sleeve plates 802 respectively, the extension sleeve plates 802 are arranged in T shape, the engagement racks 804 are slidingly connected to the top of the stand 1, the middle part of the two sides of the stand 1 are both provided with cavities 803, the two side extension sleeve plates 802 are slidingly connected to the inner walls of the two side extension sleeve plates 802 respectively, the top of the stand 1 is fixedly connected with shaft seats 806 on both sides, the middle parts of the two side shaft seats 806 are both rotatably connected with transmission rods 807, the outer wall center positions of the two side transmission rods 807 are both fixedly connected with transmission gears 805, the bottom of the transmission gear 805 is meshingly connected to the top of the engagement rack 804; It should be noted that with the downward movement of the engagement module 3, the bottom end of the two side engagement support plates 801 expands outward, further driving the extension sleeve plates 802 to move outward along the inner wall of the cavity 803. This horizontal displacement is transmitted to the transmission rod 807 through the engagement rack 804 and the transmission gear 805 to form a rotary transmission. The two side transmission rods 807 are synchronously driven in the moving direction of the water sample collection in the middle part of the two side shaft seats 806 to form a positive and negative transmission.

[0033] As shown in Figure 4 and Figure 6 , the outer wall middle part of the two side transmission rods 807 is fixedly connected with an arc-shaped plate 808, the lower middle part of the two side engagement support plates 801 is slidingly connected with a marker ball rod 809, the outer wall of the two side marker ball rods 809 is sleeved with a compensation spring 812, one end of the compensation spring 812 is fixedly connected with the marker ball rod 809, the other end of the compensation spring 812 is fixedly connected with the engagement support plate 801, the top of the stand 1 is fixedly connected with a stand frame 810 on both sides, the inner wall top of the two side stand frames 810 is fixedly installed with an infrared sensor 811, the infrared sensor 811 is arranged in the middle part of the rotation track of the arc-shaped plate 808 and is located on the same straight line; It should be noted that during the downward movement of the sampling bottle 4 to intercept the water sample, the two side transmission rods 807 rotate in the direction of approaching the rubber base 5, driving the two side arc-shaped plates 808 to rotate one hundred and eighty degrees to switch positions to the outer wall of the rubber base 5. The rotation path of the two side arc-shaped plates 808 penetrates the middle part of the two side stand frames 810, respectively breaking the infrared light emitted by the two side infrared sensors 811, and then through the electrical signal, the electric heating wire integrated in the arc-shaped plate 808 is controlled by the control switch 7 to operate preheating. When the arc-shaped plate 808 rotates and switches to the outer wall of the rubber base 5, the rubber base 5 can be subjected to heat conduction treatment, transferring heat to the rubber base 5 to restore its flexibility, compensating for the hardening effect of low temperature on rubber, ensuring that the sealing surface is tightly attached, eliminating the small gaps caused by insufficient elasticity, avoiding water sample leakage, and when heated, the rubber base 5 and the sampling bottle 4 bottle opening are synchronously heated and slightly expanded. By using the thermal expansion characteristics of rubber, the gap filled with oil film is squeezed, even if there is oil film residue, the pressure generated by thermal expansion can squeeze the oil film, strengthen the sealing effect, and reduce the risk of leakage. Correspondingly, after the water sample collection sealing treatment is completed, the two side pressing plates 6 are rotated in reverse, respectively, to release the restriction on the rubber base 5, and the electric telescopic rod 2 drives the sealed water sample to move upward to separate from the sampling water area. Corresponding to this force, the extension cover plate 802 moves in the opposite direction from the original moving direction, triggering the reverse rotation of the arc-shaped plate 808. After the water sample moves into position, the arc-shaped plate 808 also rotates back to the initial position and contacts the marker ball rod 809 during rotation, generating extrusion force on the compensation spring 812 to cause deformation. The marker ball rod 809 pops out to the outside of the connecting support plate 801, indicating the end of the entire water sample collection process. When the position of the rubber base 5 is rotated and switched next time, the extrusion force on the marker ball rod 809 is eliminated, and under the action of the elastic potential energy accumulated by the deformation of the compensation spring 812, the marker ball rod 809 is reset and stored inside the connecting support plate 801. This effectively prevents improper operation by the operator when the sampling is not completed, such as moving the sampler too early, disassembling the sampling bottle 4, etc., ensuring the standardization of the sampling process and the accuracy of the sampling results, and preventing problems such as water sample leakage, pollution or collection failure caused by misoperation.

[0034] As shown in Figures 1-2 and Figures 6-10 , the pre-protection module 9 further comprises: Four groups of connecting plates 901 are fixedly connected to the outer walls of the two side transmission rods 807 at both ends, respectively. The top of the stand 1 is fixedly connected with four hollow frames 902 on the four sides. The inner walls of the four hollow frames 902 are slidingly connected with lifting columns 903. The ends of the connecting plates 901 away from the transmission rods 807 are hingedly arranged at the bottom middle part of the lifting columns 903. The outer walls of the connecting plates 901 are slidingly connected to the middle parts of the hollow frames 902. The top ends of the four lifting columns 903 are fixedly connected with the bottom of a dynamic plate 904. A plurality of fan-shaped cavities 905 are uniformly arranged on the inner wall of the dynamic plate 904. The outer walls of fan-shaped plates 908 are slidingly connected to the inner walls of the fan-shaped cavities 905. The top of the fan-shaped plate 908 is fixedly connected with a guide rod 907. A plurality of rectangular grooves are uniformly arranged on the top of the dynamic plate 904. The outer walls of the guide rods 907 are slidingly connected to the inner walls of the rectangular grooves. The inner walls of the four fan-shaped cavities 905 are provided with connecting springs 906. One end of the connecting spring 906 is fixedly connected with the dynamic plate 904, and the other end of the connecting spring 906 is fixedly connected with the guide rod 907. It should be noted that in the process of intercepting the water column, the positive and negative rotating forces are transmitted alternately, and when the sampling bottle 4 moves downward, the dynamic plate 904 moves downward under the action of the positive rotating force. Before the sampling bottle 4 is connected with the rubber base 5, the bottle mouth of the sampling bottle 4 is in contact with each sector plate 908, and each sector plate 908 moves to the inner wall of the corresponding sector cavity 905 by extruding each connecting spring 906 under the assistance of the guide rod 907. The bottle mouth and the sector plate 908 in the middle of the dynamic plate 904 are gradually extruded and contacted, the continuous downward pressure is used to scrape off the solidified oil film layer by layer, and then the connection is sealed and the heat conduction treatment of the connection area is performed. The temperature drop of the water sample caused by the low temperature environment is compensated, the detection method sensitive to the temperature of the water sample is adapted, the subsequent detection error caused by too low temperature is avoided, the low-temperature stratification or crystallization of the oil substances in the water sample is slowed down, and the uniformity of the water sample composition during detection is ensured. Correspondingly, when the water sample is transmitted upward and reset, the sampling bottle 4 and the rubber base 5 penetrate the through hole in the middle of the dynamic plate 904, and under the action of the reverse rotating force, the bottom of the sampling bottle 4 moves a distance synchronously to form a bottom receiving protection. According to the process requirements, the heat conduction temperature compensation and the physical protection mode are switched.

[0035] A method for using a water quality oil sampler, applied to a water quality oil sampler, comprising the following steps: Step 1: Place the rubber base 5 on the top of the stand 1 and directly below the sampling bottle 4, and rotate the two side plates 6 to cover the outer wall top of the rubber base 5 to complete the fixation, then place the stand 1 into the water sample collection area, and rotate the sampling bottle 4 into the bottom of the connection module 3, drive the sampling bottle 4 to move downward along the outer wall of the stand 1 by the electric telescopic rod 2, penetrate the water column at the liquid level into the inside of the sampling bottle 4, and connect with the rubber base 5 during the continuous downward movement to seal the water sample; Step 2: As the water sample collection moves downward, the two side connection boards 801 at the bottom expand outward under the downward force of the connection module 3, further driving the extension sleeve plate 802 to move outward along the inner wall of the cavity 803, and the horizontal displacement is transmitted to the transmission rod 807 to form a rotating transmission through the connection rack 804 and the transmission gear 805; During the downward movement of the sampling bottle 4 driven by the electric telescopic rod 2, the two side connecting plates 901 rotate downward under the rotating transmission of the transmission rod 807 in the direction of the movement of the sampling bottle 4, and the dynamic plate 904 moves to the rubber base 5 under the cooperation of the hollow frame 902 and the lifting column 903. During the downward movement and connection of the sampling bottle 4, the outer wall of the bottle mouth is extruded and contacted with the top of each sector plate 908 to strip the solidified oil film attached thereto; As the sampling bottle 4 and the rubber base 5 are docked in place, the curved plates 808 on both sides rotate from their original positions to symmetrical positions on the outer wall of the rubber base 5 under the action of the rotational transmission force. After passing through the interior of the vertical frame 810 to interrupt the infrared rays emitted downward by the infrared sensor 811, the heating wire module provided in the curved plates 808 starts to operate. After the curved plates 808 on both sides are switched into place, heat is transferred to the rubber base 5 and the bottle mouth of the sampling bottle 4, helping the rubber base 5 to restore its elasticity and melting the solid oil film remaining at the bottle mouth of the sampling bottle 4, thereby eliminating the gap between the two and ensuring the tightness of the connection. Step 3: After the sampling bottle 4 is docked with the rubber base 5, the sealing of the water sample collection is completed. Then, the pressure pieces 6 on both sides are rotated in the opposite direction to release the restriction of the rubber base 5, and the electric telescopic rod 2 is driven in the opposite direction to make the sampling bottle 4 and the rubber base 5 move upward and pass through the central through-hole of the dynamic plate 904 to reset. As the sampling bottle 4 moves, the connecting module 3 drives the extension sleeves 802 on both sides to move toward the inner wall of the cavity 803 through the connecting support plates 801 on both sides, and forms a reverse transmission with the connecting rack 804 and the transmission gear 805, so that the dynamic plate 904 moves upward synchronously to collect the water sample. The sampling bottle 4 and the rubber base 5 form a support at the bottom. During this process, the reverse transmission force also acts on the arc plates 808 on both sides. After the collected water sample moves and resets with the electric telescopic rod 2, the arc plates 808 on both sides also penetrate the interior of the vertical frames 810 on both sides again, and interrupt the infrared pipeline generated by the infrared sensor 811 again. The control switch 7 triggers the heating wire in the arc plate 808 to stop working through the electrical signal, and finally rotates to the initial position, contacts the marking ball rod 809, and deforms by squeezing the compensation spring 812, so that the marking ball rod 809 is in a pop-up state, marking the completion of water sample collection; Step 4: Rotate the sampling bottle 4 in the opposite direction to separate it from the bottom of the connecting module 3, and screw the sealing cap on the upper end of the bottle. Then the bottle can be directly transported to the next step of water quality and oil analysis. Working principle: First, remove the bottle cap on the top of the sampling bottle 4, screw the top of the bottle into the bottom of the connecting module 3, and place the rubber base 5 on the top of the stand 1 just below the sampling bottle 4, and move the pressing pieces 6 on both sides to cover the top of the rubber base 5 to complete the connection and fixation. Put the stand 1 as a whole into the water area to be sampled, and control the electric telescopic rod 2 by controlling the switch 7. The electric telescopic rod 2 drives the sampling bottle 4 to move downward through the connecting module 3, penetrates the water surface downward to intercept the water column, and completes the water sample collection after docking with the rubber base 5; With the downward movement of the connecting module 3, the bottom end of the connecting support plate 801 expands outward, further driving the extension sleeve plate 802 to move outward along the inner wall of the cavity 803. This horizontal displacement is transmitted to the transmission rod 807 through the connecting rack 804 and the transmission gear 805 to form a rotary transmission. The two transmission rods 807 form a positive and negative transmission in the moving direction of the water sample collection at the middle part of the two shaft seats 806. During the process of the sampling bottle 4 moving downward to intercept the water sample, the two transmission rods 807 rotate in the positive direction towards the rubber base 5, driving the two arc-shaped plates 808 to rotate 180 degrees to switch positions to the outer wall of the rubber base 5. The rotation path of the two arc-shaped plates 808 penetrates the middle part of the two vertical frames 810, respectively breaking the infrared light emitted by the two infrared sensors 811, and then operating the preheating of the electric heating wire integrated in the arc-shaped plate 808 through electrical signals controlled by the control switch 7. When the arc-shaped plate 808 rotates to switch positions to the outer wall of the rubber base 5, the rubber base 5 can be subjected to heat conduction treatment, transferring heat to the rubber base 5 to restore its flexibility, compensating for the hardening effect of low temperature on rubber, ensuring a tight fit of the sealing surface, eliminating the small gaps caused by insufficient elasticity, avoiding water sample leakage, and expanding the rubber base 5 and the sampling bottle 4 neck synchronously when heated. By utilizing the thermal expansion characteristics of rubber, the gap filled with oil film is squeezed, even if there is residual oil film, the pressure generated by thermal expansion can squeeze the oil film, strengthening the sealing effect and reducing the risk of leakage. Correspondingly, after the water sample collection and sealing treatment are completed, the two pressing plates 6 are rotated in the reverse direction to release the restriction on the rubber base 5, and the electric telescopic rod 2 drives the sealed water sample to move upward to separate from the sampling water area. Corresponding to this force, the extension sleeve plate 802 moves in the opposite direction from the original moving direction, triggering the reverse rotation of the arc-shaped plate 808. After the water sample is moved into position, the arc-shaped plate 808 also rotates to reset to the initial position, and in the process of rotation, it contacts the marker ball rod 809, generating a squeezing force on the compensation spring 812 to cause deformation. The marker ball rod 809 pops out to the outside of the connecting support plate 801, indicating the end of the entire water sample collection process. When the arc-shaped plate 808 position rotates to switch during the next heat conduction of the rubber base 5, the squeezing force on the marker ball rod 809 is eliminated and under the action of the elastic potential energy accumulated by the deformation of the compensation spring 812, the marker ball rod 809 resets and is stored inside the connecting support plate 801. This effectively prevents improper operation by the operator when the sampling is not completed, such as moving the sampler too early, disassembling the sampling bottle 4, etc., ensuring the standardization of the sampling process and the accuracy of the sampling results, preventing problems such as water sample leakage, pollution or collection failure caused by misoperation; During the process of intercepting water column, the positive and reverse rotating forces are transmitted alternately, when the sampling bottle 4 moves downward, the dynamic plate 904 moves downward under the action of the positive rotating force, before the sampling bottle 4 and the rubber base 5 are connected, the bottle mouth of the sampling bottle 4 contacts with each sector plate 908, each sector plate 908 moves to the inner wall of the corresponding sector cavity 905 by extruding each connecting spring 906 under the assistance of the guide rod 907, the bottle mouth and the sector plate 908 in the middle of the dynamic plate 904 are extruded and contacted gradually, the oil film is scraped layer by layer by using the continuous downward pressure, then the connection and sealing are carried out and the heat conduction treatment of the connecting area is carried out, the temperature drop of the water sample caused by the low temperature environment is compensated, the detection method sensitive to the water sample temperature is adapted, the subsequent detection error caused by the too low temperature is avoided, the low temperature stratification or crystallization of the oil material in the water sample is slowed down, the uniformity of the water sample composition during detection is ensured, correspondingly, when the water sample is transmitted upward and reset, the sampling bottle 4 and the rubber base 5 penetrate the through hole in the middle of the dynamic plate 904, and move a distance at the bottom of the sampling bottle 4 under the action of the reverse rotating force to form the bottom receiving protection, the heat conduction compensation and the physical protection mode are switched according to the process requirement. Finally, after the water sample collection is completed and reset, the sampling bottle 4 is taken off from the bottom of the connection module 3 by reverse rotation, and the sealing bottle cap is rotated on the outer wall of the top bottle mouth of the sampling bottle 4, which is convenient for subsequent transportation of the collected water sample for oil component determination.

10. A method for using a water quality oil sampler, applied to a water quality oil sampler according to claims 1-9, characterized in that: The following steps are involved: Step 1: Place the rubber base (5) on the top of the stand (1) and directly below the sampling bottle (4), and rotate the pressing pieces (6) on both sides to cover the top of the outer wall of the rubber base (5). After the stand (1) is fixed, place the stand (1) in the water sample collection area, and rotate and twist the sampling bottle (4) into the bottom of the connecting module (3). Drive the sampling bottle (4) downward along both sides of the outer wall of the stand (1) through the electric telescopic rod (2), penetrate the liquid surface, intercept the water column in the interior of the sampling bottle (4), and dock with the rubber base (5) during the continuous downward movement to seal the water sample; Step 2: As the water sample collection path moves downward, the bottoms of the two connecting support plates (801) on both sides, which are subjected to the downward force of the connecting module (3), expand outward, further driving the extension sleeve (802) to move outward along the inner wall of the cavity (803). This horizontal displacement is transmitted to the transmission rod (807) through the connecting rack (804) and the transmission gear (805) to form a rotational transmission; When the electric telescopic rod (2) drives the sampling bottle (4) to move downward, the connecting plates (901) on both sides rotate downward in the direction of movement of the sampling bottle (4) under the rotation of the transmission rod (807), and the hollow frame (902) and the lifting column (903) cooperate to drive the dynamic plate (904) to move to the rubber base (5) to the right position. When the sampling bottle (4) moves downward and docks, the outer wall of the bottle mouth is squeezed and contacted with the top of each fan-shaped plate (908), and the solidified oil film attached thereto is peeled off; As the sampling bottle (4) and the rubber base (5) are docked in place, the arc plates (808) on both sides rotate from their original positions to the outer wall of the rubber base (5) in a symmetrical position under the action of the rotational transmission force, and after passing through the interior of (810) to interrupt the infrared rays emitted downward by the infrared sensor (811), the heating wire module set inside the arc plate (808) starts to operate. After the arc plates (808) on both sides are switched into place, heat is transferred to the rubber base (5) and the bottle mouth of the sampling bottle (4), assisting the rubber base (5) to restore its elasticity and melting the solid oil film remaining at the bottle mouth of the sampling bottle (4), eliminating the gap between the two when docking to ensure the tightness of the connection; Step 3: After the sampling bottle (4) and the rubber base (5) are docked, the sealing of the water sample collection is completed. Then, the pressure pieces (6) on both sides are rotated in the opposite direction to release the restriction of the rubber base (5), and the electric telescopic rod (2) is driven in the opposite direction, so that the sampling bottle (4) and the rubber base (5) move upward and pass through the central through-hole of the dynamic plate (904) to reset. As the sampling bottle (4) moves, the connecting module (3) drives the extension sleeves (802) on both sides to move toward the inner wall of the cavity (803) through the connecting support plates (801) on both sides, and forms a reverse transmission through the connecting rack (804) and the transmission gear (805), so that the dynamic plate (904) moves upward synchronously to store the water. The sampling bottle (4) for collecting water samples and the rubber base (5) form a support at the bottom. During this process, the reverse transmission force also acts on the two side arc plates (808). After the collected water sample moves and resets following the electric telescopic rod (2), the two side arc plates (808) also penetrate the inside of the two sides (810) again and interrupt the infrared pipeline generated by the infrared sensor (811) again. The control switch (7) triggers the electric heating wire in the arc plate (808) to stop working through the electrical signal. Finally, it rotates and moves to the initial position, contacts the marking ball rod (809) and deforms by squeezing the compensation spring (812) so that the marking ball rod (809) is in a pop-up state, marking that the water sample collection is completed; Step 4: Rotate the sampling bottle (4) in reverse to separate it from the bottom of the connecting module (3), and screw the sealing cap on the upper end of the bottle mouth, and then directly transfer it to the next step of water quality oil analysis and determination.
