[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the winding frame is driven to rotate by the output shaft of the retracting and discharging motor, and the chain is released, resulting in multiple first chain links and second chain links being continuously released downward from the bottom of the transfer frame, and driving the exploration cone to be released downward together.

[0018] 2. In the present invention, the front wall and the rear wall of the transfer frame are provided with an inclined groove, so that after the second chain link carries the ejector pin into the inclined groove, the resilience of the first spring in a compressed and force-accumulated state pushes the two ejector pins to move away from each other, and the ejector pin also drives the plurality of limit blocks to move together, so that the plurality of limit blocks in the yielding circular groove move to the interior of the torsion limiting groove, resulting in rotational locking between the articulated shaft rod and the articulated shaft hole, that is, a rotational locking effect is achieved between the corresponding first chain link and the second chain link, and similarly, as the first chain link and the second chain link pass through the front and rear inclined grooves in turn, a rotational locking effect is achieved, that is, the first chain link and the second chain link after passing through the bottom of the transfer frame cannot rotate with each other, so that the plurality of first chain links and the second chain links inserted into the water are connected as a whole, which can prevent the exploration cone from swinging underwater and also prevent a section of the delivery chain located in the water from bending, thereby improving the survey accuracy.

[0019] 3. In the present invention, during the downward movement of the exploration cone, the first thing that contacts the bottom of the river channel is the touch ball. When the bottom of the touch ball contacts the bottom of the river channel, the exploration cone continues to move downward, causing the push rod to slide upward along the inner wall of the telescopic hole, and under the connection of the four connecting rods, the plugging ring is driven to slide upward along the inner wall of the silt collection and suction chamber. The fourth spring is compressed and stored, and the upward movement of the plugging ring causes the two silt collection and suction holes to form a conductive effect with the interior of the silt collection and suction chamber, and the external silt can enter the interior of the silt collection and suction chamber through the two silt collection and suction holes. At the same time, the plugging ring moves upward, and its top contacts the end inclined surfaces of the two top wedge blocks to produce The wedge force acts to push the two top wedge blocks in opposite directions, further driving the two guide blocks to slide along the inner walls of the two guide grooves. The third spring is compressed, and the sliding of the two guide blocks drives the two bottom wedge blocks to slide respectively into the inside of the two guide grooves and move away from the bottom of the suction piston ring, so that the second spring in the stretched state is rebounded, pushing the suction piston ring downward along the inner wall of the silt collection and suction chamber, resulting in negative pressure inside the silt collection and suction chamber. Under the negative pressure inside the silt collection and suction chamber, the time for silt to pass through the two silt collection and suction holes and enter the silt collection and suction chamber can be accelerated, thereby accelerating the efficiency of riverbed silt collection.

Two telescopic grooves 2021 are provided inside the second link 202, and the position of the telescopic groove 2021 corresponds to the position of the hinge shaft rod 2020. A top pin 2022 is slidably installed inside the hinge shaft rod 2020, wherein the front and rear two top pins A first spring 2023 is fixedly installed between the hinge shaft 2020 and the hinge shaft 2022, a plurality of strip grooves 2024 are formed through the outer wall of the hinge shaft 2020, a plurality of limit blocks 2025 are fixedly installed on the outer wall of the top pin 2022, the limit blocks 2025 slide through the inside of the strip grooves 2024, the exploration cone 4 is fixedly installed at the bottom end of a first chain link 201 at the bottom, the number and specifications of the limit blocks 2025 are adapted to the number and specifications of the torque limiting grooves 2013, and the positions of the limit blocks 2025 correspond one to one to the positions of the torque limiting grooves 2013;

[0040] The front wall and the rear wall of the transfer frame 103 are both provided with an oblique groove 104, and the first spring 2023 is located inside the telescopic groove 2021, the aperture of the telescopic groove 2021 is the same as the inner diameter of the hinge shaft 2020, and the telescopic groove 2021 is concentric with the hinge shaft 2020;

[0041] The end of the ejector pin 2022 away from the first spring 2023 is provided with a chamfer 2026;

[0042] Specifically, the output shaft of the retractable motor 106 drives the central axis of the reel-up rack 102 to rotate, thereby driving the reel-up rack 102 to rotate along the inside of the rotating installation slot 101, unwinding the delivery chain wound inside the reel-up rack 102, causing multiple first chain links 201 and second chain links 202 to be continuously released downward from the bottom of the transfer frame 103, and driving the exploration cone 4 to be released downward together. When the first chain link 201 and the second chain link 202 enter the interior of the transfer frame 103 from the interior of the chain storage frame 1, due to the effect of the inclined slot 104 provided on the front and rear walls of the transfer frame 103, the second chain link 202 carries the ejector pin 2022 into the interior of the inclined slot 104, and the rebound force of the first spring 2023 in the compressed and stored state pushes the two ejector pins 2022 to move away from each other, and the ejector pin 2022 also drives multiple limit blocks 202. 5 moves together, so that the multiple limit blocks 2025 in the yielding circular groove 2012 move to the inside of the torsion limiting groove 2013, resulting in rotation locking between the hinge shaft 2020 and the hinge shaft hole 2011, that is, the corresponding first chain link 201 and the second chain link 202 are rotationally locked.

[0043] It should be additionally explained that, when the river depth exploration work is completed, the surveyor starts the retractable discharge motor 106 to reverse, and the output shaft of the retractable discharge motor 106 drives the reel-up frame 102 to rotate in the opposite direction, and reels the plurality of first chain links 201 and the second chain links 202 again, causing the exploration cone 4 to be lifted upward from the river bottom. At the same time, the first chain link 201 and the second chain link 202 move from the bottom of the transfer frame 103 to the inside of the transfer frame 103 in sequence, and the upward movement of the first chain link 201 drives the articulated shaft rod 2020, the top pin 2022 and the first spring 2023 to move together, and since the end of the top pin 2022 is provided with a chamfer 2026, after the articulated shaft rod 2020 moves to the bottom of the transfer frame 103, the chamfer 2026 is provided. Under the action of the wedge force between 2026 and the inner wall of the inclined groove 104, the top pin 2022 is pushed toward the inside of the telescopic groove 2021, thereby driving the multiple limit blocks 2025 fixedly connected to the articulated shaft 2020 to move together, and slide from the inside of the torque limiting groove 2013 into the inside of the circular groove 2012. After the limit blocks 2025 slide from the inside of the torque limiting groove 2013 into the inside of the circular groove 2012, the articulated shaft 2020 and the articulated shaft hole 2011 can rotate freely, that is, the corresponding first chain link 201 and the second chain link 202 can rotate freely, so that the first chain link 201 and the second chain link 202 can be wound around the inside of the winding frame 102, which is convenient for storing longer delivery chains.

[0046] A touch ball 5015 is fixedly installed at the bottom of the push rod 504, and a fourth spring 5016 is sleeved on the outer periphery of the push rod 504. The fourth spring 5016 is fixedly installed between the bottom of the exploration cone 4 and the top of the touch ball 5015;

[0047] An air suction piston ring 507 is slidably mounted on the outer wall of the ejector rod 504, and the outer wall of the air suction piston ring 507 is slidably connected to the inner wall of the silt extraction and suction chamber 501. A second spring 508 is sleeved on the outer periphery of the ejector rod 504, and the second spring 508 is fixedly mounted between the bottom of the air suction piston ring 507 and the bottom wall of the silt extraction and suction chamber 501. Two guide grooves 509 are provided on the inner wall of the silt extraction and suction chamber 501, and the two guide grooves 509 are symmetrically distributed about the center of the silt extraction and suction chamber 501, and guide blocks 5010 are slidably mounted inside the two guide grooves 509. A top wedge 5011 is fixedly installed on the top of the guide block 5010, a bottom wedge 5012 is fixedly installed on the bottom of the guide block 5010, the top of the bottom wedge 5012 abuts against the bottom of the suction piston ring 507, two third springs 5013 distributed up and down are fixedly installed inside the guide groove 509, the third spring 5013 is fixedly installed between the guide block 5010 and the inner wall of one side of the guide groove 509, and an electromagnet 5014 is fixedly installed on the bottom wall of the silt extraction and suction chamber 501, and the electromagnet 5014 is located on the periphery of the ejector rod 504;

[0048] Specifically, the output shaft of the retracting and discharging motor 106 drives the central axis of the reel-up frame 102 to rotate, thereby driving the reel-up frame 102 to rotate along the inside of the rotating installation groove 101, unwinding the delivery chain wound inside the reel-up frame 102, causing multiple first chain links 201 and second chain links 202 to be continuously released downward from the bottom of the transfer frame 103, and driving the exploration cone 4 to be released downward together. When the exploration cone 4 moves downward, the first thing that contacts the bottom of the river channel is the touch ball 5015. When the bottom of the touch ball 5015 contacts the bottom of the river channel, the exploration cone 4 continues to move downward, causing the push rod 504 to slide upward along the inner wall of the telescopic hole 503, and under the connection of the four connecting rods 505, the blocking ring 506 is driven to slide upward along the inner wall of the silt collection and suction chamber 501. The fourth spring 5016 is compressed and stored, and the blocking ring 506 moves upward, causing the two silt collection and suction holes 502 to form a conductive effect with the inside of the silt collection and suction chamber 501, so that the external silt can be The suction piston ring 507 is pressed against the bottom surface of the suction piston ring 507, and the suction piston ring 507 is pressed against the bottom surface of the suction piston ring 507. ...

[0049] It should be additionally explained that, when the river channel depth exploration and riverbed sludge collection work are completed, the survey personnel start the reversal of the retractable discharge motor 106, and the output shaft of the retractable discharge motor 106 drives the reel-up frame 102 to rotate in the opposite direction, and reels the multiple first chain links 201 and the second chain links 202 again, causing the exploration cone 4 to be lifted upward from the river bottom, carrying the silt collection components and the collected riverbed silt upward together. During this period, the rebound force of the fourth spring 5016 drives the push rod 504, the connecting rod 505 and the blocking ring 506 to reset downward, and the two silt collection suction holes 502 are blocked again to prevent the collected silt from the two silt collection holes 502. The suction hole 502 leaks out. When the exploration cone 4 is lifted to the top dead center, the surveyor pushes the touch ball 5015 upward, and further drives the blocking ring 506 upward through the push rod 504 and the connecting rod 505, so that the two silt collection and suction holes 502 are connected with the inside of the silt collection and suction chamber 501 again. Then the electromagnet 5014 is turned on, and the electromagnet 5014 is energized to generate a magnetic force between the suction piston ring 507, pushing the suction piston ring 507 upward, and the silt inside the silt collection and suction chamber 501 is discharged through the two silt collection and suction holes 502, so that the surveyor can detect the silt on the riverbed.

[0050] In the present scheme, a multifunctional surveying device is used by the surveyor holding the handle of the plastic shell 6, and the device is placed on the surface of the water area to be surveyed. The device is powered by an external power supply, and the power harness plug of the device is inserted into the power socket, and the circuit is turned on. Then, the surveyor starts the retractable discharge motor 106, and drives the central axis of the reel-up frame 102 to rotate through the output shaft of the retractable discharge motor 106, thereby driving the reel-up frame 102 to rotate along the inside of the rotating installation groove 101, and unwinding the delivery chain wound on the reel-up frame 102, causing multiple first chain links 201 and second chain links 202 to be continuously released downward from the bottom of the transfer frame 103, and driving the exploration cone 4 to be released downward together. At the same time, the sensing end of the sensor 3 calculates the downward movement distance of the exploration cone 4 by sensing the number of downward movements of the first chain link 201 and the second chain link 202, so that when the exploration cone 4 reaches the bottom, the data counted by the sensor 3 can know the depth of the river channel;

[0051] When the first link 201 and the second link 202 enter the interior of the transfer frame 103 from the interior of the chain storage frame 1, due to the effect of the inclined groove 104 provided on the front wall and the rear wall of the transfer frame 103, the second link 202 carries the ejector pin 2022 into the interior of the inclined groove 104, and the rebound force of the first spring 2023 in the compressed and stored force state pushes the two ejector pins 2022 to move away from each other, and the ejector pin 2022 also drives the plurality of limit blocks 2025 to move together, so that the plurality of limit blocks 2025 in the yielding circular groove 2012 move to the interior of the torsion limiting groove 2013, resulting in the rotation locking between the articulated shaft 2020 and the articulated shaft hole 2011, that is, the corresponding first link 201 and the second link The first chain link 201 and the second chain link 202 are locked in rotation. Similarly, after the first chain link 201 and the second chain link 202 pass through the front and rear inclined slots 104 in sequence, the first chain link 201 and the second chain link 202 cannot rotate with each other after passing through the bottom of the transfer frame 103, so that the multiple first chain links 201 and the second chain links 202 inserted into the water are connected as a whole, which can prevent the exploration cone 4 from swinging underwater and the bending problem of a section of the delivery chain located in the water, thereby improving the survey accuracy. At the same time, the device has a compact structure, is easy to operate and carry, and is helpful for the survey of the river. At the same time, the compact structure can also reduce the production and procurement costs;

[0052] When the exploration cone 4 moves downward, the first thing that contacts the bottom of the river channel is the touch ball 5015. When the bottom of the touch ball 5015 contacts the bottom of the river channel, the exploration cone 4 continues to move downward, causing the push rod 504 to slide upward along the inner wall of the telescopic hole 503, and under the connection of the four connecting rods 505, the blocking ring 506 is driven to slide upward along the inner wall of the silt collection and suction chamber 501. The fourth spring 5016 is compressed and stores force, and the blocking ring 506 moves upward, causing the two silt collection and suction holes 502 to form a conductive effect with the interior of the silt collection and suction chamber 501, and the external silt can enter the interior of the silt collection and suction chamber 501 through the two silt collection and suction holes 502. At the same time, the blocking ring 506 moves upward, and its top contacts the end inclined surfaces of the two top wedge blocks 5011 to generate a wedge force. The two top wedge blocks 5011 are pushed in opposite directions, further driving the two guide blocks 5010 to slide along the inner walls of the two guide grooves 509, and the third spring 5013 is compressed. The two guide blocks 5010 slide and drive the two bottom wedge blocks 5012 to slide into the inside of the two guide grooves 509 respectively, and move away from the bottom of the suction piston ring 507, so that the second spring 508 in the stretched state is rebounded, and the suction piston ring 507 is pushed downward along the inner wall of the silt collection and suction chamber 501, resulting in negative pressure inside the silt collection and suction chamber 501. Under the negative pressure inside the silt collection and suction chamber 501, the time for the silt to pass through the two silt collection and suction holes 502 and enter the silt collection and suction chamber 501 can be accelerated, thereby accelerating the efficiency of riverbed silt collection;

[0053] When the river channel depth exploration and riverbed silt collection work are completed, the surveyor starts the retracting and discharging motor 106 to reverse, and the output shaft of the retracting and discharging motor 106 drives the reel-up frame 102 to rotate in the opposite direction, and reels the multiple first chain links 201 and the second chain links 202 again, causing the exploration cone 4 to be lifted upward from the river bottom, carrying the silt collection components and the collected riverbed silt upward together. During this period, the rebound force of the fourth spring 5016 drives the push rod 504, the connecting rod 505 and the blocking ring 506 to reset downward, and the two silt collection suction holes 502 are blocked again to prevent the collected silt from the two silt collection holes 502. The suction hole 502 leaks out. At the same time, the first link 201 and the second link 202 move from the bottom of the transfer frame 103 to the inside of the transfer frame 103 in sequence. The first link 201 moves upward to drive the hinge shaft 2020, the top pin 2022 and the first spring 2023 to move together. Since the end of the top pin 2022 is provided with a chamfer 2026, after the hinge shaft 2020 moves to the bottom of the transfer frame 103, the top pin 2022 is pushed toward the inside of the telescopic slot 2021 under the action of the wedge force between the chamfer 2026 and the inner wall of the inclined slot 104, thereby bringing The plurality of limit blocks 2025 fixedly connected to the articulated shaft 2020 move together and slide from the interior of the torque limiting groove 2013 into the interior of the circular groove 2012. After the limit blocks 2025 slide from the interior of the torque limiting groove 2013 into the interior of the circular groove 2012, the articulated shaft 2020 and the articulated shaft hole 2011 can rotate freely, that is, the corresponding first chain link 201 and the second chain link 202 can rotate freely, so that the first chain link 201 and the second chain link 202 can be wound inside the winding frame 102, which is convenient for storing the longer delivery chain. When the exploration cone 4 is lifted to the top dead center, the surveyor pushes the touch ball 5015 upward, and further drives the blocking ring 506 to move upward through the push rod 504 and the connecting rod 505, so that the two silt extraction and suction holes 502 are connected with the inside of the silt extraction and suction chamber 501 again, and then the electromagnet 5014 is turned on. The electromagnet 5014 is energized to generate a magnetic force between the suction piston ring 507, pushing the suction piston ring 507 upward, and the silt inside the silt extraction and suction chamber 501 is discharged through the two silt extraction and suction holes 502, so that the surveyor can detect the silt on the riverbed.
