DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with preferred embodiments. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0023] The accompanying drawings are schematic diagrams of embodiments of the present invention. It should be noted that the drawings are only examples and are not drawn in proportion, and should not be used as a limitation on the actual protection scope of the present invention.

[0024] A shallow river and lake bottom mud collection tool, such as Figure 1 As shown, it includes a colander 1, a telescopic rod 2 and a traction rope 3. The colander 1 is a cylinder with an opening on one side, and a circular water leakage hole 11 is provided on the cylindrical side of the colander 1. A fixing ring 12 is provided on the bottom surface of the end of the colander 1 away from the opening; a pulley 121 is fixed to the fixing ring 12, and a traction rope 3 is connected to the pulley 121. The telescopic rod 2 is composed of multiple sections of embedded tubes; the top of the innermost section of the telescopic rod 2 is fixed to the open end of the colander 1. A rope protection groove 21 is provided in the middle position of the outer surface of the outermost section of the telescopic rod 2, and a protruding groove 22 is provided on the outermost section of the telescopic rod 2 at a position 10 mm close to one end of the colander 1, and any section except the outermost section is provided with a protruding groove 22 at a position 10 mm away from both ends. A rope collection shaft 231 is provided at the tail end of the telescopic rod 2. One end of the traction rope 3 is fixed to the rope collecting shaft 231, passes through the rope protection groove 21 and the pulley 121, and the other end is fixed to the rope protection groove 21. The telescopic rod 2 can be extended through multiple hollow embedded tubes, and the angle between the colander 1 and the bottom mud can be adjusted through the traction rope 3, so that the colander 1 can reach the bottom of the water to collect the bottom mud.

[0025] Since it is often necessary to go deep into the water to take samples during work, the colander 1 and the telescopic rod 2 are preferably made of stainless steel, which is not easy to rust; and have good hardness and will not deform; since bottom mud is often collected outdoors, the traction rope 3 should have a certain strength and be resistant to ultraviolet radiation, and nylon braided rope is preferred.

[0026] The colander 1 is cylindrical in shape, with a bottom diameter of 100 mm and a height of 200 mm. The end of the colander 1 close to the telescopic rod 2 is an opening, through which the bottom mud is scooped. Figure 2 As shown, a fixing plate 14 perpendicular to the opening is welded on the outer wall of one end of the opening of the colander 1. The fixing plates 14 are two opposite each other and are equidistant from the center axis of the colander 1. The fixing plate 14 is provided with a fixing ring, and a support rod 141 is fixed on the fixing ring. The support rod 141 can rotate within the fixing ring. The telescopic rod 2 is welded to the support rod 141. The telescopic rod 2 rotates 180 degrees on the colander 1 along the support rod 141 to adjust the angle between the opening of the colander 1 and the bottom mud of the water. The support rod 141 is located on one side close to the opening of the colander 1, and the optimal position is located at a position 1 / 3 away from one end of the opening.

[0027] The bottom surface on the side opposite to the opening of the colander 1 is closed, and a semicircular fixing ring 12 is welded at the center of the outer side surface of the bottom surface. The fixing ring 12 is perpendicular to the bottom surface of the colander 1 and also perpendicular to the plane where the support rod 141 is located. A pulley 121 is fixed in the middle position of the fixing ring 12. The bottom surface is welded together with the cylindrical side surface, tightly connected without gaps, and will not crack, and can hold the collected bottom mud. There is a partition 13 on the inner wall of the bottom surface, and batteries are contained in the partition 13; when the bottom mud is scooped up and the traction rope 3 is loosened, due to the weight of the battery in the partition 13, the colander 1 will rotate along the pulley 121, the bottom surface is close to the ground, and the colander 1 is vertically downward.

[0028] At the same time, a circular leakage hole 11 is arranged on the cylindrical side of the colander 1. The leakage holes 11 are evenly arranged at a distance of 10 mm from the top of the opening of the colander 1. The diameter of the leakage holes 11 is 2 mm. Each row is the size of a leakage hole 11, which ensures that the colander 3 has a certain strength and the water can be leaked out in time. When the colander 1 probes to the bottom of the water to collect the bottom mud, it will inevitably scoop up river water or lake water, so the water carried in the bottom mud is discharged from the leakage holes 11, and the bottom mud at the bottom of the water is collected.

[0029] An ultrasonic radar 15 is provided at the part of the colander 1 near the opening end, opposite to the support rod 141. The ultrasonic radar 15 can transmit and receive ultrasonic waves. An ultrasonic radar switch is connected to the ultrasonic radar 15 through an electric wire. The ultrasonic radar switch is arranged next to the ultrasonic radar 15 and close to the ultrasonic radar 15. The electric wire connecting the ultrasonic radar 15 and the ultrasonic radar switch can be arranged on the inner wall of the colander 1. The commonly used operating frequencies of the ultrasonic radar 15 are 40kHz, 48kHz and 58kHz. The higher the frequency, the higher the sensitivity, but the smaller the detection angle in the horizontal and vertical directions. The utility model adopts a 40kHz ultrasonic radar 15 with a detection range of 0.1-3 meters. The ultrasonic radar 15 is waterproof and dustproof, and is suitable for monitoring and collecting underwater sediments.

[0030] The ultrasonic radar 15 is electrically connected to the buzzer 16, and the buzzer 16 can be set on the cylindrical side wall of the colander 1 perpendicular to the ultrasonic radar 15. When the ultrasonic radar 15 emits an ultrasonic wave, the ultrasonic wave propagates and reflects underwater and is received again by the ultrasonic radar 15. When the received signal changes, an electric current is generated and sent to the buzzer 16, and the buzzer 16 emits a buzz. The ultrasonic radar 15, the ultrasonic radar switch and the buzzer 16 are all connected to the battery by wires, and the battery is placed in the partition 13, and the connecting wires are placed on the inner wall of the colander 1.

[0031] An infrared detector 17 is installed on the side of the ultrasonic radar 15 away from the opening. The infrared detector 17 is provided with an infrared detector switch. The infrared detector 17 is electrically connected to the display screen 24. When the buzzer 16 sounds, the infrared detector 17 emits infrared light and converts it into an electrical signal and outputs it to the display screen 24 to display the underwater environment. The infrared detector 17 is also connected to the battery to supply power and ensure normal operation. The wires connecting the battery and the infrared detector 17 are placed in the side wall of the colander 1.

[0032] The telescopic rod 2 is a hollow embedded tube made of multiple sections of stainless steel. Figure 3 As shown, the outermost section of the telescopic rod 2 is provided with a raised groove 22 at a position 10 mm close to one end of the colander; except for the outermost section, any other inner sections are provided with raised grooves 22 at a position 10 mm away from both ends. The raised grooves 22 are arranged circumferentially on each section of the telescopic rod 2 to ensure that each section of the telescopic rod 2 is stuck with its two adjacent sections through the raised grooves 22 after extension, and will not fall off from each other.

[0033] The tube wall thickness of the telescopic rod 2 is 0.8mm, and the length of the telescopic rod 2 increases by 10mm from the outermost section to the innermost section, and the thickness decreases by one wall thickness. Each section of the telescopic rod 2 in the inner layer can enter a section of the telescopic rod 2 in the outer layer, and the multi-section telescopic rod 2 can be fully retracted; when fully retracted, the length of the telescopic rod 2 is equal to the length of the innermost section. Any section of the telescopic rod 2 should be greater than or equal to 100mm, so that there is enough space inside to store each section; and any section of the telescopic rod 2 should also be less than or equal to 500mm. After retracting, the shallow river and lake bottom mud collection tool is small enough and easy to carry; and after being extended, it is long enough to ensure that the colander 1 can reach the bottom of shallow rivers and lakes to collect bottom mud.

[0034] The top of the innermost section of the telescopic rod 2 is welded to the outer surface of the support rod 141 to collect bottom mud. When using the shallow river and lake bottom mud collection tool for sampling, the telescopic rod 2 is extended so that the colander 1 reaches the bottom of the water for sampling. After the sampling is completed, the telescopic rod 2 is retracted to facilitate the collection of the collected bottom mud. The small size makes it easy to carry. A rope protection groove 21 is welded in the middle position of the outermost section of the telescopic rod 2. The rope protection groove 21 is semi-cylindrical. The length of the rope protection groove 21 should be less than or equal to the length of the outermost section of the telescopic rod 2. The inner diameter of the rope protection groove 21 should be at least larger than the size of the traction rope 3 to ensure that the traction rope 3 can be accommodated.

[0035] The telescopic rod 2 is at the tail end portion of the outermost section away from the colander 1, and the side walls of the telescopic rod 2 are respectively provided with a shell 23, and the shell 23 is two opposite shells, such as Figure 3 As shown, the formed internal space has a rope collection shaft 231. The diameter of the shell 23 is smaller than the distance between the telescopic rod 2 and the tail end of the colander 1; the distance between the shells 23 can be appropriately increased, but should be smaller than or equal to the diameter of the colander 1, and the shell 23 and the telescopic rod 2 can be fixed by a connecting plate.

[0036] A coaxial rope collecting shaft 231 is installed in the housing 23. The rope collecting shaft 231 is cylindrical, and the diameter of the rope collecting shaft 231 is smaller than the diameter of the housing 23. The thickness of the rope collecting shaft 231 is equal to the distance between the housings 23. It is ensured that the traction rope 3 can be completely stored in the rope collecting shaft 231 to prevent it from falling off. A handle 232 is provided on the outside of the housing 23. The handle 232 is connected to the rope collecting shaft 231. By shaking the handle 232, the rope collecting shaft 231 can be rotated along the axial direction to wrap the traction rope 3 around the rope collecting shaft 231.

[0037] The telescopic rod 2 is provided with a display screen 24 between the rope collecting shaft 231 and the rope protection groove 21. The display screen 24 is electrically connected to the infrared detector 17 to display the underwater environment monitored by the infrared detector 17 in real time. The display screen 24 is perpendicular to the telescopic rod 2, and the display screen 24 and the buzzer 16 are located in the same plane. The length of the display screen 24 is less than the length of the colander 1. The wire connecting the display screen 24 and the infrared detector 17 is placed in the inner wall of the opening end of the colander 1 and the telescopic rod 2, and the length of the wire is greater than the total length of the telescopic rod 2. When the telescopic rod 2 is fully extended, the wire can ensure that the display screen 24 and the infrared detector 17 are well connected, and after the sampling is completed, the telescopic rod 2 is extended, and the wire can be stored in the telescopic rod 2. The display screen 24 is also connected to a battery to ensure energy supply. The display screen 24 displays the underwater environment. By moving the position of the shallow river and lake sediment collection tool, the sediment is collected avoiding underwater obstructions, and misjudgment of obstacles caused by changes in ultrasonic signals generated by the ultrasonic radar 15 for fish, shrimp and other organisms can be avoided.

[0038] One end of the traction rope 3 is fixed on the rope protection groove 21, passes through the pulley 121 on the bottom surface of the colander 1, passes through the rope protection groove 21, and the other end is fixed on the rope collection shaft 231, and the traction rope 3 as a whole forms a ring loop. In the part between the rope protection groove 21 and the colander 1, the traction rope 3 is two strands parallel to each other, and there is a certain angle between the traction rope 3 and the telescopic rod 2; in the part between the rope protection groove 21 and the rope collection shaft 231, the traction rope 3 is one strand, close to the telescopic rod 2, and parallel to the telescopic rod 2. By shaking the handle 232, the rope collection shaft 231 is rotated forward or reversed to tighten or loosen the traction rope 3, and the angle of the colander 1 can be adjusted. When the traction rope 3 is tightened, the colander 1 is parallel to the ground or the angle is obtuse. At this time, the opening of the colander 1 is close to the bottom mud, which makes it easier to scoop the bottom mud for sampling.

[0039] The length of the traction rope 3 should be at least twice the total length of the telescopic rod 2 after it is fully extended, to ensure that when the telescopic rod 2 is fully extended, the colander 1 can enter the water bottom to collect the bottom mud, and the traction rope 3 is fixed through the rope protection groove 21 on the outside of the telescopic rod 2. By pulling the traction rope 3, the angle between the colander 1 and the underwater bottom mud can be adjusted to ensure that the complete bottom mud can be collected. When the collection is completed, turn the handle 232 and appropriately loosen the traction rope 3. The colander 1 will move vertically downwards together with the collected bottom mud under the weight of the battery in the compartment 13. When collecting the bottom mud, the water scooped out will flow out from the circular leakage hole 11 on the cylindrical side of the colander 1, collect the bottom mud, pour the bottom mud out of the stainless steel colander 1, repeat the collection several times, and complete the sampling.

[0040] The corresponding project of this invention is "Simulation of the Evolution of the Yangtze River Mainstream Water Ecosystem and Health Assessment System", numbered 2022YFC3202002, which belongs to the National Key R&D Program. According to the provisions of Guozhifayunzi

[2024] No. 3, the patents of financial scientific research projects that have not been implemented for more than five years without justifiable reasons are applicable. The state can implement them free of charge, or authorize others to implement them for a fee or free of charge.

[0041] A shallow river and lake bottom mud collection tool, the colander 1 is an open cylindrical shape, with a simple structure and convenient sampling; and the cylindrical side of the colander 1 is evenly spaced with circular leakage holes 11, which prevents the bottom mud from blocking the leakage holes 11 compared to setting the leakage holes 11 at the bottom of the colander 1, and the water can be filtered out faster during the sampling process; and the colander 1 is controlled by the combined action of the traction rope 3 and the telescopic rod 2, which is more labor-saving. Secondly, the telescopic rod 2 is a multi-section hollow embedded tube with lower weight, smaller volume, and easy to carry; when in use, the telescopic rod 2 is extended according to the depth of the water body. In addition, the angle of the colander 1 can be adjusted by pulling the traction rope 3, and can be adjusted in real time during the collection process. Finally, there is an ultrasonic radar 15 on the cylindrical side of the colander 1, which can detect the underwater environment of the area to be collected. When there are objects such as stones, branches, and water plants that affect the collection of bottom mud, the buzzer 16 will make a sound to remind the operator, and the infrared detector 17 will use thermal imaging and display the real-time underwater situation on the display screen. In summary, the shallow river and lake bottom mud collection tool of the present application can quickly and safely collect bottom mud in shallow water bodies without wading or using a boat.
