The sampler is installed on the unmanned ship and is controlled by the instructions of the unmanned ship to automatically complete sampling of specified depth and specified water volume, achieve the purpose of water quality stratified sampling, and fully understand the water quality condition of the water area. The sampler has the characteristics of small size, light weight and simple use. However, due to the influence of the water depth of the sampling area, the sampling head is prone to touch the bottom during pipe laying. When the pipe is continuously laid, the pipe is over-laid, and the depth of the sampling head does not change, which leads to pipe confusion, inconsistent sampling depth and pipe laying length, affects the experimental data of the later detection, and seriously affects the accuracy of the analysis results of the later experimental data. UTILITY MODEL CONTENTS

[0003] The utility model embodiment provides a kind of shipborne water quality stratified intelligent sampler, to be able to solve the problem that water quality sampler in prior art cannot be found in time when sampling head touches bottom during working process to affect data accuracy.

[0004] To achieve the above object, the technical scheme adopted by the utility model is as follows: a shipborne water quality stratified intelligent sampler is provided, comprising:

[0008] A guide wheel is rotatably arranged on the guide wheel seat, and the position of the guide wheel on the guide wheel seat has a degree of freedom for free movement along the direction close to or away from the axis of the winch. The sampling pipe is arranged on the outside of the guide wheel and extends downward.

[0009] A sampling head is installed on the other end of the sampling pipe.

[0010] A travel switch is installed on the guide wheel seat, and the control end of the travel switch abuts against the guide wheel.

[0012] In a possible implementation, the travel switch is mounted on one side of the guide wheel seat, and the control end of the travel switch extends into the interior of the guide wheel seat and abuts against the rotating shaft of the guide wheel.

[0013] In a possible implementation, a protective ring is installed on the guide wheel seat to prevent the guide wheel seat from scratching the sampling tube, and the sampling tube is passed through the inside of the protective ring.

[0014] In a possible implementation, a plurality of flexible fins are provided on the inner wall of the protective ring, and the plurality of flexible fins abut against the outer wall of the sampling tube to scrape off impurities on the outside of the sampling tube.

[0015] In a possible implementation, an annular groove for accommodating the sampling tube is formed on the outer side of the guide wheel, and a pressure plate for limiting the sampling tube in the annular groove is installed on the guide wheel seat.

[0016] In a possible implementation, a sensor for sensing the sampling head is further installed at the bottom of the guide wheel seat.

[0017] In a possible implementation, there are multiple sensors, and the sensors are evenly spaced apart along the circumference of the sampling tube and arranged outside the sampling tube.

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] Please also refer to Figures 1 to 3 , the shipborne water quality stratification intelligent sampler provided by the present invention is now described. The shipborne water quality stratification intelligent sampler includes a guide wheel seat 1, a winch 2, a sampling tube 3, a guide wheel 4, a sampling head 5 and a travel switch 6. The winch 2 is rotatably set on the guide wheel seat 1; the sampling tube 3 is wound around the outside of the winch 2, and one end of the sampling tube 3 is fixedly mounted on the winch 2; the guide wheel 4 is rotatably set on the guide wheel seat 1, and the position of the guide wheel 4 on the guide wheel seat 1 has the freedom to move freely in the direction close to or away from the axis of the winch 2, and the sampling tube 3 is overlapped on the outside of the guide wheel 4 and extended downward; the sampling head 5 is installed at the other end of the sampling tube 3; the travel switch 6 is installed on the guide wheel seat 1, and the control end of the travel switch 6 rests on the guide wheel 4.

[0027] Compared with the prior art, the shipborne water quality stratification intelligent sampler provided in this embodiment is provided with a guide wheel seat 1, a winch 2 is rotatably provided on the guide wheel seat 1, a guide wheel 4 is rotatably provided on one side above the winch 2, and the guide wheel 4 is rotatably provided on the guide wheel seat 1. The sampling tube 3 is wound around the winch 2, and one end of the sampling tube 3 extends out of the winch 2 and overlaps the top of the guide wheel 4. It extends downward out of the guide wheel seat 1 through the guidance of the guide wheel 4, and a sampling head 5 is also installed at the end of the sampling tube 3. The sampling head 5 drives the sampling tube 3 to move toward the bottom of the water according to its own gravity, so as to assist the sampling tube 3 to enter the bottom of the water for sampling. In this application, the guide wheel 4 is designed to slide freely on the guide wheel seat 1, so that when the sampling tube 3 is normally released, the guide wheel 4 moves toward the axis of the winch 2 under the action of the gravity of the sampling head 5, and moves toward the inside of the travel switch 6 against the control end of the travel switch 6. When the sampling head 5 hits the bottom, the sampling tube 3 loses its pulling force, and the guide wheel 4, driven by the control end of the limit switch 6, moves away from the axis of the capstan 2. Simultaneously, the control end of the limit switch 6 shifts and generates a switch signal. Based on this signal, the control end determines whether the sampling head 5 has hit the bottom. This stops the tube release operation, preventing continuous tube release from causing confusion in the pipeline and ensuring accurate sample collection.

[0028] Specifically, in this embodiment, the travel switch 6 is electrically connected to the controller, and controls the rotation of the winch 2 by sending a signal to the controller. The control method of the controller is the existing technology and will not be elaborated here.

[0029] Specifically, in this embodiment, the height of the axis of the guide wheel 4 on the guide wheel seat 1 is higher than the height of the axis of the winch 2 on the guide wheel seat 1 .

[0030] Specifically, in this embodiment, the travel switch 6 adopts the existing technology, and the travel switch 6 is equipped with an elastic member for pushing the control end of the travel switch 6 to move outward, so that when the sampling head 5 touches the bottom, the control end can move outward and push the guide wheel 4 to move away from the axis of the capstan 2.

[0031] Preferably, in this embodiment, one end of the sampling tube 3 extends into the interior of the sampling head 5 , and the side wall of the sampling head 5 is a filter mesh, which can play a filtering effect during the sampling process of the sampling tube 3 .

[0032] In some embodiments, the guide wheel seat 1 can be used as follows Figure 1 、 Figure 2 See also Figure 1 、 Figure 2The guide wheel seat 1 is also mounted with a guide seat 7, on which the rotation shaft 41 of the guide wheel 4 is slidably mounted. A guide seat 7 is fixedly mounted on both sides of the guide wheel seat 1. Each guide seat 7 has an oblong through-hole for mounting the rotation shaft 41 of the guide wheel 4. The two ends of the rotation shaft 41 are respectively located within the oblong through-holes of the two guide seats 7. The length direction of the oblong through-holes is tilted downward in the direction close to the capstan 2.

[0033] Preferably, in this embodiment, the moving direction of the control end on the travel switch 6 is set along the length direction of the oblong through hole, so that when the guide wheel 4 moves on the guide seat 7, it can drive the control end on the travel switch 6 to move.

[0034] In some embodiments, the travel switch 6 can be used as follows Figure 2 See the structure shown. Figure 2 The travel switch 6 is mounted on one side of the guide seat 7, and the control end of the travel switch 6 extends into the interior of the guide seat 7 and abuts against the rotating shaft 41 of the guide wheel 4. The outer housing of the travel switch 6 is fixedly mounted on the guide wheel seat 1 and is located on one side of the guide seat 7. The control end of the travel switch 6 extends into the interior of the guide seat 7 and abuts against the outer surface of the rotating shaft 41 of the guide wheel 4. Therefore, when the rotating shaft 41 is displaced on the guide seat 7, it can drive the control end of the travel switch 6 to move together, thereby realizing the switching of the state of the travel switch 6.

[0035] Preferably, in this embodiment, a roller is rotatably provided at the end of the control end of the travel switch 6 for abutting against the outer side of the rotating shaft 41 of the guide wheel 4, and the axis of the roller is spaced and parallel to the axis of the guide wheel 4. This facilitates the rotation of the rotating shaft 41 of the guide wheel 4 on the guide seat 7.

[0036] In some embodiments, the guide wheel seat 1 can be used as follows Figure 3 See the structure shown. Figure 3 A protective ring 11 is installed on the guide wheel seat 1 to prevent the guide wheel seat 1 from scratching the sampling tube 3. The sampling tube 3 is inserted into the protective ring 11. A clearance hole for the sampling tube 3 to extend downward is provided below the guide wheel 4. A protective ring 11 is installed on the inner wall of the clearance hole. The sampling tube 3 is inserted into the protective ring 11, thereby protecting the pipeline and preventing the guide wheel seat 1 from scratching the sampling tube 3.

[0037] Specifically, in this embodiment, a mounting plate is detachably mounted on the bottom of the guide wheel seat 1 , and the protective ring 11 is mounted on the mounting plate, thereby facilitating the installation and removal of the protective ring 11 .

[0038] In some embodiments, the protective ring 11 may be formed as follows: Figure 3 See the structure shown. Figure 3The inner wall of the protective ring 11 is provided with multiple flexible fins 111, which abut against the outer wall of the sampling tube 3 to scrape away impurities on the outside of the sampling tube 3. Multiple flexible fins 111 are protruding from the inner wall of the protective ring 11, and the flexible fins 111 abut against the outer wall of the sampling tube 3. When the sampling tube 3 is in operation, water samples or green algae attached to the outside of the sampling tube 3 can be scraped away by the flexible fins 111. This prevents water from accumulating inside the guide wheel seat 1 and corroding the interior.

[0039] Specifically, in this embodiment, the flexible fins 111 and the protective ring 11 are an integrally formed structure.

[0040] In some embodiments, the guide wheel 4 can be used as follows Figure 1 、 Figure 2 See also Figure 1 、 Figure 2 The outer side of the guide wheel 4 is recessed with an annular groove for accommodating the sampling tube 3, and a pressure plate 8 is installed on the guide wheel seat 1 for limiting the sampling tube 3 inside the annular groove. The size of the annular groove is adapted to the outer size of the sampling tube 3. The sampling tube 3 is located inside the annular groove, which can play a certain guiding role in the transportation of the sampling tube 3. In addition, a pressure plate 8 is detachably mounted on the guide wheel seat 1, and the pressure plate 8 is located directly above the guide wheel 4. When the sampling tube 3 is located inside the annular groove, the pressure plate 8 is located above the sampling tube 3, which can prevent the sampling tube 3 from detaching from the guide wheel 4 from above. When the sampling head 5 touches the bottom, the sampling tube 3 sometimes becomes loose relative to the guide wheel 4. The setting of the pressure plate 8 can prevent the sampling tube 3 from detaching from the guide wheel 4.

[0041] In some embodiments, the guide wheel seat 1 can be used as follows Figure 3 See the structure shown. Figure 3 The bottom of the guide wheel seat 1 is also equipped with a sensor 12 for sensing the sampling head 5. The sensor 12 is installed at the bottom of the guide wheel seat 1, with the sensing end of the sensor 12 facing downward and located on one side of the output port of the sampling tube 3. When the sampling tube 3 is stored on the winch 2, the sampling head 5 moves upward. When the sensor 12 senses the sampling head 5, it sends a signal to the control end. After the control end receives the signal, the sampling head 5 is stored in place, and the winch 2 can stop continuing to store the sampling tube 3. It is used to automatically control the storage of the sampling head 5.

[0042] Specifically, in this embodiment, a magnet corresponding to the position of the sensor 12 is installed on the top of the sampling head 5 , and the sensor 12 uses a sensing element for detecting magnets, such as a magnet sensor.

[0043] In some embodiments, the sensor 12 may be configured as follows: Figure 3 See the structure shown. Figure 3The number of the inductors 12 is multiple, and the multiple inductors 12 are uniformly arranged on the outer side of the sampling tube 3 along the circumference of the sampling tube 3. The multiple inductors 12 are fixedly installed on the bottom of the guide wheel base 1, and the sampling tube 3 is located in the middle of the multiple inductors 12. When the single inductor 12 inducts the sampling head 5, the signal is fed back to the control end, and the winch 2 is controlled to stop rotating by the control end. Through the arrangement of the multiple inductors 12, the shaking of the sampling head 5 in the tube collecting process is avoided, and when the inductor 12 is inducted, the bottle is adhered to the guide wheel base 1, and the damage of each component is avoided.

[0044] In some embodiments, the winch 2 can adopt the structure as shown in Figure 1 . Referring to Figure 1 , the outer side of the winch 2 is fixedly installed with a detection block 21, and the guide wheel base 1 is further installed with a detector 13 for detecting the position of the detection block 21. The detection block 21 is installed on the outer side of the winch 2, the detection block 21 is a magnet, and the detector 13 is an inductive element for detecting the magnet, for example, a magnet sensor. The installation position of the detection block 21 is arranged in the interval of the axis of the winch 2. The guide wheel base 1 is further installed with the detector 13 for detecting the position of the detection block 21. The detection of the detector 13 on the detection block 21 can record the rotation number of the winch 2, so as to determine the tube length of the sampling tube 3, and the operation of fixed depth sampling is achieved.

[0045] Preferably, in the embodiment, the sampling tube 3 is wound on the winch 2 in a single-layer multi-layer winding mode, which occupies small space, is convenient for controlling the tube length, and can effectively ensure the tube precision.

[0046] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
