Description

Technical Field

[0001] This utility model relates to the field of water sampling technology, specifically to an unmanned vessel automatic stratified sampling device. Background Technology

[0002] In fields such as environmental monitoring, hydrological research, and marine resource surveys, sampling and analysis of water at different depths is a crucial step in obtaining key data. Unmanned surface vessels (USVs), with their high degree of automation and ability to operate in complex waters, have become important tools for water sampling. However, existing automated stratified sampling devices for USVs face several problems that urgently need to be addressed in practical applications.

[0003] Traditional unmanned surface vessel (USV) stratified sampling devices often have complex stratification adjustment mechanisms, lacking sufficient precision and flexibility. When collecting water samples at different depths, it is difficult to quickly and accurately adjust the sampling mechanism to the target depth, affecting sampling efficiency. Furthermore, existing sampling devices are prone to tangling and knotting of the inlet pipe during deployment and retraction, obstructing the sampling process and potentially damaging the equipment.

[0004] Therefore, there is an urgent need for an unmanned surface vessel automatic stratified sampling device that can achieve precise stratified adjustment and orderly inlet pipe deployment and retraction to meet the demand for efficient and accurate sampling in practical applications. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model discloses an automatic stratification sampling device for unmanned vessels. The technical solution adopted is as follows: an unmanned vessel is included, in which a battery and a control module are fixedly installed in the cavity at the rear of the unmanned vessel, a wireless communication module is fixedly installed on the top of the unmanned vessel, and two fixed plates are fixedly installed on the top of the unmanned vessel, with a stratification adjustment mechanism installed on the two fixed plates.

[0006] The layered adjustment mechanism includes guide rods, a rotating plate, a drum, a square rod, pulleys, a belt, and a motor. Two guide rods are provided, one end of each guide rod is fixedly connected to the end face of the rotating plate, and the other ends of the guide rods pass through two through holes on one of the fixed plates. The other end face of the rotating plate is rotatably connected to the end face of the drum. The middle of the other end face of the drum is fixedly connected to one end of the square rod. The other end of the square rod passes through a through hole in a bearing seat on another fixed plate. A pulley is slidably mounted on the square rod. The motor is fixedly mounted on the top of the unmanned vessel, and the output shaft of the motor is fixedly connected to the end face of the other pulley. The two pulleys are connected by a belt. The water inlet pipe of the automatic sampling mechanism is wound around the drum.

[0007] The automatic sampling mechanism includes a pressure sensor, a counterweight, a pulley seat, a water inlet pipe, a rotary joint, a sample bottle, a water outlet pipe, a solenoid valve, and a sampling pump. The sample bottle is inserted into a groove on the protruding part of the unmanned surface vessel's top. The pulley seat is rotatably mounted on one side of the unmanned surface vessel's top. One end of the water inlet pipe is fixedly connected to the top of the counterweight. The counterweight has a through hole that mates with the water inlet pipe. The water inlet pipe is located in a pulley groove at the upper end of the pulley seat. The rotary joint is fixedly installed in a through hole in the middle of the end face of the drum. One end of the rotary joint inside the drum is connected to the other end of the water inlet pipe. The water inlet pipe is spirally wound on the drum. The rotary joint is located at one end of the outer side of the reel and connected to one end of the water outlet pipe. The other end of the water outlet pipe is closed. The water outlet on the side of the water outlet pipe is connected to the water inlet on the top of the sample bottle. Several sample bottles are provided. A solenoid valve is installed on the water outlet of the water outlet pipe. A sampling pump is installed on the water outlet pipe. The sampling pump is fixedly installed on the top of the unmanned vessel. Through holes that cooperate with the water outlet pipe are opened on the sides of the rotating plate and the fixed plate. A pressure sensor is fixedly installed on the top of the counterweight. The battery, wireless communication module, pressure sensor, solenoid valve, sampling pump and motor are electrically connected to the control module.

[0008] As a preferred technical solution of this utility model, one end of the square rod located on the outside of the fixed plate is fixedly connected to the middle of the end face of the rotating rod. The side of the rotating rod is provided with a spiral groove that is connected end to end. The top of the unmanned boat is fixedly installed with an inverted U-shaped fixed seat. A fixed rod is fixedly installed in the top of the fixed seat, and the fixed rod is located in the spiral groove.

[0009] As a preferred embodiment of this utility model, a U-shaped baffle is fixedly installed on the side of the upper end of the pulley seat, and the baffle is located on the outside of the water inlet pipe.

[0010] In a preferred embodiment of this invention, a filter cylinder is fixedly installed at the bottom of the counterweight. In another preferred embodiment of this invention, a Y-shaped fixing fork is fixedly installed at the top of the unmanned vessel, with the upper ends of the fixing fork located on both sides of the pulley on the square rod.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses a motor to drive a pulley to rotate, which in turn drives another pulley via a belt, causing the square rod and drum to rotate. When the drum rotates, the water inlet pipe wound around it can be extended or retracted, thereby causing the counterweight and pressure sensor to descend or rise. The pressure sensor monitors the water pressure, enabling the unmanned surface vessel to accurately identify the sampling depth and achieve precise adjustment of the sampling depth. Multiple sample bottles are inserted into the groove on the top of the unmanned surface vessel, and a solenoid valve is installed on the outlet of the water pipe. The control module can precisely control the opening and closing of the solenoid valve to achieve water sample distribution to different sample bottles without manual intervention, thus improving the automation level of sample collection.

[0013] 2. When the square rod rotates, the rotating rod rotates accordingly. The cooperation between the spiral groove and the fixed rod causes the rotating rod to move axially while rotating, enabling the drum to move axially back and forth during rotation. This guides the water inlet pipe to wind or unwind in an orderly manner on the drum, avoiding tangling or knotting during the winding and unwinding process. This ensures stable sampling operation. The baffle can limit the water inlet pipe, preventing it from coming out of the pulley groove during winding and unwinding, ensuring that the water inlet pipe moves along the predetermined path and improving the reliability of sampling.

[0014] 3. The filter cartridge can perform preliminary filtration of the water sample entering the inlet pipe, removing larger impurity particles in the water and preventing impurities from entering the sample bottle and sampling system, thus ensuring the purity of the collected water sample. The fixed fork can position the pulley and prevent the pulley from shifting during rotation, ensuring the stable operation of the stratification adjustment mechanism and thus ensuring the reliability of the entire sampling process.

Detailed Implementation

[0021] Example 1

[0022] like Figures 1 to 5 As shown, this utility model discloses an automatic stratified sampling device for unmanned vessels. The technical solution adopted is as follows: an unmanned vessel 1 is included. A battery 2 and a control module 3 are fixedly installed in the cavity at the rear of the unmanned vessel 1. A wireless communication module 4 is fixedly installed on the top of the unmanned vessel 1. Two fixed plates 7 are fixedly installed on the top of the unmanned vessel 1. A stratification adjustment mechanism 6 is installed on the two fixed plates 7.

[0023] The layered adjustment mechanism 6 includes guide rods 61, a rotating plate 62, a drum 63, a square rod 64, a pulley 65, a belt 66, and a motor 67. Two guide rods 61 are provided; one end of each guide rod 61 is fixedly connected to the end face of the rotating plate 62, and the other end of each guide rod 61 passes through two through holes on one of the fixed plates 7. The other end face of the rotating plate 62 is rotatably connected to the end face of the drum 63. The middle of the other end face of the drum 63 is fixedly connected to one end of the square rod 64. The other end of the square rod 64 passes through a through hole in a bearing seat on another fixed plate 7. The end of the square rod 64 located outside the fixed plate 7 is connected to the rotating plate 62. The middle of the end face of the moving rod 8 is fixedly connected, and the side of the rotating rod 8 has a spiral groove 9 that is connected end to end. The top of the unmanned boat 1 is fixedly installed with an inverted U-shaped fixed seat 10. The top of the fixed seat 10 is fixedly installed with a fixed rod 11, which is located in the spiral groove 9. When the square rod 64 rotates, the rotating rod 8 rotates accordingly. The cooperation between the spiral groove 9 and the fixed rod 11 causes the rotating rod 64 to move axially while rotating, so that the drum 63 can move axially back and forth during the rotation, thereby guiding the water inlet pipe 54 to wind or unwind in an orderly manner on the drum 63, avoiding the water inlet pipe from being damaged. 54. To address the issues of tangling and knotting during deployment and retraction, and to ensure stable sampling operation, a pulley 65 is slidably mounted on the square rod 64. A Y-shaped fixing fork 14 is fixedly mounted on the top of the unmanned vessel 1. The upper ends of the fixing fork 14 are located on both sides of the pulley 65 on the square rod 64. The fixing fork 14 can position the pulley 65, preventing it from shifting during rotation, thus ensuring the stable operation of the stratification adjustment mechanism 6 and the reliability of the entire sampling process. The motor 67 is fixedly mounted on the top of the unmanned vessel 1, and the output shaft of the motor 67 is connected to another belt. The end face of wheel 65 is fixedly connected, and the two pulleys 65 are connected by belt 66. The water inlet pipe 54 of the automatic sampling mechanism 5 is wound on the drum 63. The pulley 65 is driven to rotate by motor 67, and the other pulley 65 is driven by belt 66, which in turn makes the square rod 64 and the drum 63 rotate. When the drum 63 rotates, the water inlet pipe 54 wound on it can be retracted, thereby driving the counterweight 52 and pressure sensor 51 to descend or rise. The water pressure is monitored by pressure sensor 51, so that the unmanned boat 1 can accurately identify the sampling depth and achieve accurate adjustment of the sampling depth.

[0024] The automatic sampling mechanism 5 includes a pressure sensor 51, a counterweight 52, a pulley seat 53, a water inlet pipe 54, a rotary joint 55, a sample bottle 56, a water outlet pipe 57, a solenoid valve 58, and a sampling pump 59. The sample bottle 56 is inserted into a groove on the protruding part of the top of the unmanned vessel 1. The pulley seat 53 is rotatably mounted on one side of the top of the unmanned vessel 1. One end of the water inlet pipe 54 is fixedly connected to the top of the counterweight 52. The counterweight 52 has a through hole that matches the water inlet pipe 54. A filter cartridge 13 is fixedly installed at the bottom of the counterweight 52. The filter cartridge 13 can be used to sample the water entering the water inlet pipe 54. Preliminary filtration removes larger impurities from the water, preventing them from entering the sample bottle 56 and the sampling system, thus ensuring the purity of the collected water sample. The inlet pipe 54 is located in the pulley groove at the upper end of the pulley seat 53. A U-shaped baffle 12 is fixedly installed on the side of the upper end of the pulley seat 53, located outside the inlet pipe 54. The baffle 12 limits the inlet pipe 54, preventing it from coming out of the pulley groove during operation and ensuring that the inlet pipe 54 moves along the predetermined path, thus improving the reliability of sampling. The rotary joint 55 is fixedly installed on the end face of the reel 63. Inside the central through-hole, one end of the rotary joint 55 located inside the drum 63 is connected to the other end of the inlet pipe 54, which is spirally wound around the drum 63. The other end of the rotary joint 55 located outside the drum 63 is connected to one end of the outlet pipe 57, which is closed. The outlet on the side of the outlet pipe 57 is connected to the inlet at the top of the sample bottle 56. Several sample bottles 56 are provided. A solenoid valve 58 is installed at the outlet of the outlet pipe 57. A sampling pump 59 is installed on the outlet pipe 57 and is fixedly mounted on the top of the unmanned vessel 1. The rotating plate 62 and... The side of the fixed plate 7 has a through hole that matches the water outlet pipe 57. The top of the counterweight 52 is fixedly installed with a pressure sensor 51. The battery 2, wireless communication module 4, pressure sensor 51, solenoid valve 58, sampling pump 59 and motor 67 are electrically connected to the control module 3. Multiple sample bottles 56 are inserted into the groove on the top of the unmanned boat 1. The water outlet of the water outlet pipe 54 is equipped with a solenoid valve 58. The control module 3 can precisely control the opening and closing of the solenoid valve 58 to realize the distribution of water samples from different sample bottles 56 without manual intervention, thus improving the automation of sample collection.

[0025] The working principle of this utility model is as follows: A sampling command is sent to the wireless communication module 4 on the unmanned boat 1 through an external control terminal (such as a computer, mobile phone, etc.). After receiving the command, the wireless communication module 4 transmits the signal to the control module 3.

[0026] After receiving the sampling command, control module 3 starts motor 67. The output shaft of motor 67 drives the connected pulley 65 to rotate. Through the transmission of belt 66, another pulley 65 rotates accordingly, which in turn drives the square rod 64 to rotate. When the square rod 64 rotates, the drum 63, which is fixedly connected to the square rod 64, rotates synchronously. Since the water inlet pipe 54 is wound on the drum 63, the rotation of the drum 63 causes the water inlet pipe 54 to begin to unwind. When the drum 63 unwinds the water inlet pipe 54, the counterweight 52 connected to one end of the water inlet pipe 54 gradually descends under its own weight, simultaneously driving the pressure sensor 51 to descend. The pressure sensor 51 monitors the water pressure in real time during the descent and converts the water pressure data into an electrical signal, which is transmitted to control module 3. Control module 3 compares and analyzes the preset sampling depth with the water pressure data fed back by pressure sensor 51. When the depth corresponding to the water pressure detected by pressure sensor 51 reaches the preset sampling depth, control module 3 controls motor 67 to stop rotating. At this time, the counterweight 52 and the water inlet pipe 54 stop descending, and the sampling mechanism reaches the target sampling depth.

[0027] During the sampling process, control module 3 starts sampling pump 59. Sampling pump 59 begins to work, generating suction at one end of water inlet pipe 54. Under the action of suction, water enters water inlet pipe 54 through filter cartridge 13 at the bottom of counterweight block 52. Filter cartridge 13 can filter out larger impurity particles in the water, ensuring that the water sample entering water inlet pipe 54 is relatively pure.

[0028] Water samples from inlet pipe 54 enter outlet pipe 57 via rotary joint 55. The outlet on the side of outlet pipe 57 is connected to the inlet at the top of sample bottle 56. Control module 3 controls the opening and closing of solenoid valve 58 according to a preset water sample distribution scheme. When water samples need to be collected into a specific sample bottle 56, control module 3 controls the solenoid valve 58 connected to that sample bottle 56 to open, allowing water samples to flow into that sample bottle 56 under the action of sampling pump 59. After sampling of one sample bottle is completed, control module 3 closes the solenoid valve 58 and then controls the opening of the solenoid valve 58 corresponding to the next sample bottle to be sampled, thus completing the collection of multiple water samples at different depths in sequence.

[0029] During the rotation of the drum 63 to wind up and unwind the water inlet pipe 54, the square rod 64 drives the rotating rod 8 to rotate. The spiral groove 9 on the side of the rotating rod 8 cooperates with the fixed rod 11 at the top of the fixed base 10, causing the rotating rod 8 to move axially while rotating. Since the rotating rod 8 is fixedly connected to the square rod 64, and the square rod 64 is fixedly connected to the drum 63, the drum 63 will move axially back and forth during rotation. This axial back and forth movement can guide the water inlet pipe 54 to wind or unwind in an orderly manner on the drum 63, avoiding tangling or knotting of the water inlet pipe 54 during winding up and unwinding.

[0030] Meanwhile, the baffle 12 on the upper side of the pulley seat 53 limits the water inlet pipe 54, preventing the water inlet pipe 54 from coming out of the pulley groove during the opening and closing process, ensuring that the water inlet pipe 54 moves along the predetermined path, and further ensuring the stable operation of the sampling mechanism.

[0031] After water samples are collected at all depths, control module 3 restarts motor 67, causing it to reverse and drum 63 to begin retracting inlet pipe 54. Counterweight 52 and pressure sensor 51 rise as inlet pipe 54 retracts until they return to their initial positions. Afterward, unmanned vessel 1, based on instructions received from control module 3, returns to shore or continues performing other tasks.

[0034] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
