Description

Technical Field

[0001] This invention relates to an environmental protection detection technology, and more particularly to a multi-parameter water quality detection system and method for unmanned vessels. Background Technology

[0002] Unmanned surface vessels (USVs) are robots that operate automatically on water, requiring no remote control and relying on precise satellite positioning and their own sensors to complete pre-set tasks. The use of USVs fundamentally solves the difficulties of water-based operations, particularly the issue of manpower. Operations that previously required multiple personnel can now be conducted remotely from a control room without human intervention. However, when USVs perform water quality testing in large bodies of water, they need to collect water samples. The limited sample container capacity on USVs means that each patrol can only bring back a small number of samples. This is especially true when testing multiple parameters across multiple areas and conditions, requiring a significantly larger number of samples. Existing USVs typically only collect samples from a fixed, limited-capacity container within the vessel during a single patrol. Collecting more samples necessitates multiple patrols, greatly reducing the efficiency of USVs in multi-parameter water quality testing. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a multi-parameter water quality detection system for unmanned vessels, which effectively improves the efficiency of multi-parameter detection and sampling during unmanned vessel cruise and reduces the operating cost of unmanned vessels.

[0004] The technical solution of this invention is:

[0005] A multi-parameter water quality detection system for unmanned vessels, comprising a control center and unmanned vessel devices;

[0006] The unmanned vessel device includes at least one unmanned vessel; the control center is connected to the unmanned vessel via wireless signal.

[0007] The unmanned vessel is equipped with a hull, and the hull is equipped with a wireless signal module for signal connection with the control center.

[0008] The hull is equipped with multiple testing chambers, each containing a water quality testing device. The sample inlet of the testing device is connected to a sampling device via a delivery pipeline. The sampling device includes a sampling pump and a sampling tap. The sampling tap has a single inlet and dual outlet structure. Its inlet is connected to the sampling pipeline, its first outlet is connected to the sample inlet of the testing device via the delivery pipeline, and its second outlet is connected to the sample interface via the sample pipeline.

[0009] The hull contains a sample box compartment, which includes a sample box stacking cavity. Below the stacking cavity is a sequential lowering mechanism, and below that is a sample filling cavity. The side wall of the filling cavity has a sample interface with an opening and closing mechanism. This mechanism includes a semi-circular mounting slot that rotates around the interface. One end of the slot is fixed to a rotating push rod, and one end of the opening and closing drive rod is sleeved on the push rod. The other end of the drive rod is connected to the output of a reciprocating mechanism. The sample box includes a float at the top and a bottom plate connected to the float. A sample bag is fixedly connected to the sample box. The sample bag is made of flexible material. The front end of the sample bag is provided with a sampling interface. The sampling interface is provided with a rotary valve that can be opened and closed. When the sampling interface is stacked in the sample box compartment, it faces the hanging slot below. The sampling interface can be hooked onto the hanging slot. The opening and closing mechanism controls the opening and closing of the sampling valve. A push-out mechanism is provided on the lower side wall of the sample interface, opposite the hanging slot. The push-out mechanism includes a push-out rod. The end of the push-out rod is used to push the sample box away from the hanging slot. The other end of the push-out rod is connected to a push-out drive mechanism.

[0010] The unmanned vessel is equipped with a control device, which is connected to the control center via the wireless signal module. The control device is also connected to each of the detection devices, sampling pumps, sampling taps, drop-down mechanisms, opening and closing mechanisms, and push-out mechanisms.

[0011] In the unmanned surface vessel multi-parameter water quality detection system described above, the sample box float is equipped with a positioning device.

[0012] As described above, in the unmanned surface vessel multi-parameter water quality detection system, each of the sample boxes has a collar on one side of its float plate, a reel on the sample box compartment, a connecting rope wound on the reel, the connecting rope passing through each collar, and the collar being connected to the float plate via a pivot connection; an opening is provided on the rear side wall of the sample box compartment, the opening communicating with the external water surface, allowing the sample box containing the sample to float out of the vessel through the opening.

[0013] As described above, in the unmanned vessel multi-parameter water quality detection system, the sample interface is connected to a manifold switching mechanism, the manifold switching mechanism has multiple branch pipes, each branch pipe is equipped with a solenoid valve, and each branch pipe is connected to a second outlet. Each solenoid valve is signal-connected to a control device.

[0014] The unmanned surface vessel multi-parameter water quality detection system described above includes a sample container transport vessel, which is signal-connected to the control center. The sample container transport vessel has multiple connecting buckles evenly distributed at a set interval on its outer periphery. The connecting buckles are elastic open sleeve mechanisms, including a first elastic clamp and a second elastic clamp arranged opposite each other. The mating ends of the first elastic clamp and the second elastic clamp are elastic and abut against each other to form an elastic clamp mechanism.

[0015] The collar is an electrically operated collar structure composed of two semi-circular structures, one end of which can be opened and closed. The electrically operated collar structure is signal-connected to the control center. Multiple horizontally arranged docking crossbars are provided around the float of the sample box. The docking crossbars are fixed to the outside of the float of the sample box via fixing rods. The length of the fixing rods is greater than the length of the first elastic clamping rod and the second elastic clamping rod.

[0016] In the unmanned surface vessel multi-parameter water quality detection system described above, each of the sample boxes has an electromagnet device on the side of its float plate, and the electromagnet device is signal-connected to the control center.

[0017] A method for multi-parameter water quality detection on unmanned surface vessels, wherein the unmanned surface vessel multi-parameter water quality detection system described above is used, and the steps are as follows:

[0018] 1. Control the unmanned vessel to cruise along the predetermined route and proceed to the designated testing point to conduct water quality testing and sampling;

[0019] 2. Upon arrival at the designated testing point, use the testing equipment to perform multi-parameter water quality testing and send the data to the control center for recording;

[0020] III. Collect water samples from the testing sites;

[0021] Fourth, control the unmanned vessel to return and collect the collected water samples.

[0022] As can be seen from the above description, the present invention does indeed have the following advantages:

[0023] The unmanned surface vessel (USV) multi-parameter water quality detection system and method of this invention are ingeniously designed with a sample container compartment for storing stacked sample boxes. This allows for the storage of a large number of sample boxes within a small space inside the USV. During cruise detection and sampling according to a pre-set route, it avoids the need for multiple cruise operations due to excessive water sample collection within the USV, greatly improving the efficiency of USV use.

[0042] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0043] This invention proposes a multi-parameter water quality detection system for unmanned vessels, and in a preferred embodiment, such as... Figures 1 to 5 As shown, the unmanned surface vessel (USV) multi-parameter water quality detection system of the present invention includes a control center 1 and an unmanned surface vessel (USV) device; the USV device includes at least one USV 2; the control center 1 and the USV 2 are connected via wireless signal; the USV 2 has a hull, and the hull is equipped with a wireless signal module 12 for signal connection with the control center 1; the hull is equipped with multiple detection chambers, each detection chamber is equipped with a water quality detection device 4, the sample inlet of the detection device 4 is connected to a sampling device via a delivery pipeline, the sampling device includes a sampling pump 5 and a sampling tap, the sampling tap has a single inlet and dual outlet structure, its inlet is connected to the sampling pipeline, its first outlet is connected to the sample inlet of the detection device 4 via the delivery pipeline, and its second outlet is connected to the sample interface 7 via the sample pipeline; when the USV 2 starts water quality detection on the water, multiple water quality parameters can be detected by the different detection devices 4 configured in the multiple detection chambers set in the hull. The first outlet can send the pumped water sample to the testing device 4 for testing, while the second outlet can send the pumped water sample to the sample interface 7 and then inject it into a designated container for sample collection; preferably, the two processes can be performed simultaneously.

[0044] The hull is equipped with a sample box compartment, which contains a sample box stacking cavity 10. Below the sample box stacking cavity 10 is a sequential lowering mechanism, and below the sequential lowering mechanism is a sample filling cavity 9. Preferably, the sample box compartment is divided into two areas from top to bottom: the upper area is for stacking sample boxes 3, and the lower area is the working space for filling water samples into the sample boxes. The middle area is supported by a sequential lowering mechanism that can support the stacked sample boxes 3. This sequential lowering mechanism can be based on the structural principle of a sequential lowering mechanism found in vending machines. Preferably, two horizontal rollers are provided on the side wall of the sample box compartment below the sample box stacking cavity 10. Multiple horizontal support plates are provided on the rollers, and these support plates are evenly distributed at equal angles. When the rollers are rotated, a pair of support plates rotates downwards, sending the sample boxes 3 held on these two support plates into the lower sample filling cavity 9. The next pair of support plates then rotates to support the next sample box 3 below the upper pair. Of course, the sequential lowering mechanism can also be other structures, as long as it can support the stacked sample boxes 3 one by one and allow the sample boxes 3 to fall one by one. Preferably, the bottom of the sample box compartment is connected to the water surface, while the sample box stacking cavity 10 and the sample filling cavity 9 are both located above the water surface.

[0045] The sample filling chamber 9 has a sample interface 7 on its side wall, and an opening and closing mechanism 8 on the sample interface 7. The opening and closing mechanism 8 includes a semi-circular hanging groove 84 that can rotate around the sample interface 7. One end of the hanging groove 84 is connected to a rotating push rod 81, and one end of the opening and closing drive rod 82 is sleeved on the rotating push rod 81. The other end of the opening and closing drive rod 82 is connected to the output end of a reciprocating push mechanism 83. The sample box 3 includes a float plate 32 set on the top and a sample bag 33 fixedly connected to the bottom of the float plate 32. The sample bag 33 is made of a flexible material. Preferably, it can be a retractable, sealed, waterproof bag structure. Its material can be one or more materials such as rubber and canvas. When the sample bag 33 is not filled with water sample, it can be flattened and stacked together. The front end of the sample bag 33 is provided with a sampling interface 31, and the sampling interface 31 is provided with a rotary opening and closing sampling valve. When the sampling interface 31 is stacked in the sample box compartment, it faces the hanging slot 84 below. The sampling interface 31 can be hung on the hanging slot 84, and the opening and closing of the sampling valve is controlled by driving the opening and closing mechanism 8. The lower side wall of the sample interface 7 is provided with a push-out mechanism 15 at the position facing the hanging slot 84. The push-out mechanism 15 includes a push-out rod, the end of which is used to push the sample box 3 away from the hanging slot 84. The other end of the push-out rod is connected to a push-out driving mechanism. As shown in the figure, the sample box 3 is equipped with a sampling interface 31. When stored in the sample box stacking cavity 10, all sampling structures are positioned in the same direction. When the sample box 3 falls, the sampling interface 31 directly faces the sample interface 7. Due to the setting of the hanging groove 84, the sampling interface 31 will fall into the hanging groove 84 and be directly opposite the sample interface 7 after falling in. Then, the sample filling operation can be performed.

[0046] After the sample collection is completed, the opening and closing drive rod 82 is driven to push the rotating push rod 81, causing the hanging slot 84, which is fixedly connected to the rotating push rod 81, to rotate around the sample interface 7. The hanging slot 84 has a protruding structure that is linked to the inlet valve of the sampling interface 31 of the sample box 3, which can push the rotating switch of the inlet valve on the sampling interface 31. Therefore, after pushing the hanging slot 84 upwards, the inlet valve can be closed, ensuring the sample box 3 is sealed. Because the hanging slot 84 rotates upwards, the sample interface 7 has no support below. Through the push rod of the push mechanism 15, the sample interface 7 will fall directly into the water below and float on the surface, instead of being placed on an unmanned vessel for loading and transportation.

[0047] The unmanned vessel 2 is equipped with a control device 11, which is connected to the control center 1 via the wireless signal module 12. The control device 11 is also connected to each of the aforementioned detection devices 4, sampling pumps 5, sampling taps, sequential lowering mechanisms, opening and closing mechanisms 8, and pushing mechanisms 15. Through the coordinated control of the control device 11, water quality testing and simultaneous water sampling can be effectively completed. Furthermore, water samples can be collected and transported via the sample container 3. Therefore, multiple water quality tests and water sample collections with more parameters can be performed in a single cruise, eliminating the need for multiple cruises.

[0048] In a preferred embodiment of the unmanned surface vessel (USV) multi-parameter water quality monitoring system of the present invention, as described above, a positioning device 35 is provided on the float 32 of the sample container 3. Preferably, the sample container 3 is equipped with the positioning device 35, thus allowing the USV 2 to perform more water quality tests. Simultaneously, the collected water samples can be released onto the water surface and then collected again via the positioning device 35 using other methods. This enables the USV for multi-parameter water quality monitoring to have stronger operational capabilities without needing to consider the quantity of water samples collected.

[0049] In a preferred embodiment of the unmanned surface vessel multi-parameter water quality detection system of the present invention as described above, each sample container 3 has a collar on one side of its float plate 32. A reel is provided on the sample container compartment, and a connecting rope is wound on the reel. The connecting rope passes through each collar, and the collar is pivotally connected to the float plate 32. An opening is provided on the rear side wall of the sample container compartment, communicating with the external water surface. The sample container 3, filled with samples, can float out of the hull through the opening. Preferably, the collar arrangement allows each sample container 3 to be connected together by the connecting rope. Even if it floats outside the hull through the opening, it can be transported by towing without occupying space on the hull.

[0050] In a preferred embodiment of the unmanned surface vessel multi-parameter water quality detection system of the present invention, as described above, the sample interface 7 is connected to a manifold switching mechanism 6. The manifold switching mechanism 6 has multiple branch pipes, each equipped with a solenoid valve, which is connected to each of the second outlets. Each solenoid valve is signal-connected to the control device 11. Through the manifold switching mechanism 6, a single sample container can connect to all the water sample sampling ports corresponding to the detection equipment 4, saving space on the vessel.

[0051] The preferred embodiment of the unmanned surface vessel multi-parameter water quality detection system of the present invention, as described above, is also referred to herein. Figure 6 and Figure 7As shown, the unmanned surface vessel multi-parameter water quality detection system includes a sample container transport vessel. As shown in the figure, the sample container transport vessel 13 is signal-connected to the control center 1. Multiple connecting buckles 14 are evenly distributed at a set interval on the outer periphery of the sample container transport vessel 13. The connecting buckle 14 is an elastic open sleeve mechanism, including a first elastic clamping rod 141 and a second elastic clamping rod 142 arranged opposite each other. The mating ends of the first elastic clamping rod 141 and the second elastic clamping rod 142 are elastic and abut against each other to form an elastic clamping mechanism.

[0052] The collar is an electrically operated collar structure composed of two semi-circular structures, one end of which can be opened and closed. This electrically operated collar structure is signal-connected to the control center 1. Controlling the electrically operated collar structure allows for the towing of the sample box 3 by the connecting rope and the detachment of the sample box 3 from the connecting rope. Multiple horizontally arranged docking crossbars 34 are provided around the float 32 of the sample box 3. These docking crossbars 34 are fixed to the outside of the float 32 of the sample box 3 via fixing rods. The length of the fixing rods is greater than the length of the first elastic clamping rod 141 and the second elastic clamping rod 142. Preferably, when the sample box 3 floats on the water surface, the docking crossbars 34 are horizontally arranged due to the action of the float 32. When the sample box transport vessel 13 approaches the sample box 3, the open-shaped elastic clamping mechanism collides with the docking crossbars 34, causing the docking crossbars 34 to be squeezed into the bent portion of the second elastic clamping rod 142, thereby fixing the sample box 3 around the sample box transport vessel 13 for transport back to the designated location.

[0053] In a preferred embodiment of the unmanned surface vessel multi-parameter water quality detection system of the present invention as described above, each sample box has an electromagnet device on its side of the float plate 32, and the electromagnet device is signal-connected to the control center 1. Preferably, the electromagnet device on the side of the sample box can be activated and deactivated via wireless control of the control center 1. When the electromagnet is activated, the sample boxes can approach each other and magnetically attract each other, preventing the multiple sample boxes from drifting apart and providing better towing control of the sample boxes.

[0054] The present invention proposes a multi-parameter water quality detection method for unmanned surface vessels. In a preferred embodiment, the multi-parameter water quality detection system for unmanned surface vessels described above is used, and the steps are as follows:

[0055] 1. Control the unmanned vessel to cruise along the predetermined route and proceed to the designated testing point to conduct water quality testing and sampling;

[0056] 2. Upon arrival at the designated testing point, use the testing equipment to perform multi-parameter water quality testing and send the data to the control center for recording.

[0057] III. Collect water samples from the testing sites;

[0058] Fourth, control the unmanned vessel to return and collect the collected water samples.

[0059] During water quality testing and sampling, water is drawn by a sampling pump while water quality testing and sample collection are carried out simultaneously. During the sample collection process, the flattened sample boxes stacked in the sample box compartment can be used to collect more water samples, eliminating the need for multiple cruises due to insufficient water sample containers.

[0060] The unmanned surface vessel (USV) multi-parameter water quality detection system and method of this invention are ingeniously designed with a sample container compartment for storing stacked sample boxes. This allows for the storage of a large number of sample boxes within a small space inside the USV. During cruise detection and sampling according to a pre-set route, it avoids the need for multiple cruise operations due to excessive water sample collection within the USV, greatly improving the efficiency of USV use.

[0061] The above description is merely an illustrative embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
