[0030] Through comprehensive and accurate benthic animal surveys, we can better understand and protect the ecosystems of lakes and reservoirs, and provide a scientific basis for the sustainable management and utilization of water resources. In order to investigate benthic animals, biological samples are generally obtained by collecting sediments. Thermal stratification of water bodies has a direct impact on the distribution and growth of aquatic organisms. Different water temperature layers may be suitable for the survival of different types of aquatic organisms. Thermal stratification affects the distribution of dissolved oxygen, nutrients and other substances in water bodies. In order to study the thermal stratification and dissolved oxygen distribution of water bodies, temperature and dissolved oxygen sampling are generally carried out at different depths of the water body. In related technologies, the measurement of water body temperature, dissolved oxygen distribution and benthic animal sampling are carried out separately, and in one survey, the two operations are carried out one after another, which consumes a long time and a lot of manpower.

[0031] Reference Figure 1 and Figure 2As shown, a multifunctional mud sampler of an embodiment of the utility model includes a mud grabbing bucket 100, a control component 200 and a detection component 300. The mud grabbing bucket 100 includes a first bucket portion 110 and a second bucket portion 120 which are hinged to each other. The first bucket portion 110 and the second bucket portion 120 can be moved to an open state and a closed state by rotating around a hinge point. In the closed state, the first bucket portion 110 and the second bucket portion 120 surround a receiving cavity; the control component 200 is connected to the first bucket portion 110 and the second bucket portion 120, and the control component 200 is used to drive the first bucket portion 110 and the second bucket portion 120 to switch between an open state and a closed state; the detection component 300 is arranged on the outer wall of the mud grabbing bucket 100, and the detection component 300 includes a temperature sensor, a dissolved oxygen sensor and a depth sensor. The multifunctional mud sampler of the utility model can measure the water temperature and the depth distribution of dissolved oxygen while collecting the bottom mud of the water body, thereby reducing the operation steps.

[0032] When collecting sediment from a body of water, a boat is usually taken with equipment to a designated water location. After arriving at the designated location, the grabbing bucket 100 is first released from the water surface toward the bottom of the water body. During the descent of the grabbing bucket 100, the control component 200 drives the first bucket part 110 and the second bucket part 120 to remain in an open state. The grabbing bucket 100 sinks into the sediment when it reaches the bottom of the water body by its own gravity. At this time, the control component 200 drives the first bucket part 110 and the second bucket part 120 to move to a closed state, so that the sediment can be dug into the accommodation cavity formed by the first bucket part 110 and the second bucket part 120. It should be understood that the first bucket part 110 and the second bucket part 120 are hinged to each other, so the control component 200 drives the first bucket part 110 and the second bucket part 120 to move away from each other so that the bucket can be in an open state, and the first bucket part 110 and the second bucket part 120 can be closed and maintained in a closed state when they are close to each other.

[0033] When the grab bucket 100 is lowered from the water surface toward the bottom of the water body, the detection component 300 provided on the grab bucket 100 can work synchronously to obtain the temperature and dissolved oxygen information of the environment around the grab bucket 100, that is, the temperature and dissolved oxygen information of the water body in real time, and record them together with the current depth of the grab bucket 100. Therefore, while collecting the bottom mud of the water body, the depth distribution of the water body temperature and dissolved oxygen can also be measured, reducing the operation steps.

[0034] It should be understood that the grab bucket 100 can be hoisted and moved toward the bottom of the water body by its own gravity, or a rigid object such as a rod can be used to connect the grab bucket 100 and drive the grab bucket 100 to move toward the bottom of the water body.

[0035] It can be understood that the detection assembly 300 is disposed on the first bucket portion 110 , and the detection assembly 300 is located on a side close to the rotation axis of the first bucket portion 110 .

[0036] The detection assembly 300 is generally composed of a variety of sensors, such as a temperature sensor, a dissolved oxygen sensor, and a depth c sensor. These sensors need to maintain good contact with the water body, so the detection assembly 300 is arranged on the side close to the rotation axis of the first bucket 110, so that the detection assembly 300 can be kept away from the end of the mud grabbing bucket 100 that contacts the bottom mud, so as to prevent the bottom mud from covering the detection assembly 300.

[0037] It should be understood that, in other embodiments, the detection assembly 300 may be disposed on the second bucket portion 120 and located on a side of the transmission axis close to the second bucket portion 120. The first bucket portion 110 and the second bucket portion 120 may be mirror images, so whether the detection assembly 300 is disposed on the first bucket portion 110 or the second bucket portion 120, it should be understood as the same solution.

[0038] It is understandable that the outer wall of the first bucket portion 110 is provided with a protective cavity 130 , the protective cavity 130 is provided with a water passage, the water passage is communicated with the external environment, and the detection component 300 is installed in the protective cavity 130 .

[0039] Considering that the detection component 300 can be disposed in either the first bucket portion 110 or the second bucket portion 120 , the following description will be given by taking the case where the detection component 300 is disposed in the first bucket portion 110 as an example.

[0040] The protection cavity 130 can protect the detection component 300. For example, when the grab bucket 100 moves to the bottom of the water body, the protection cavity 130 can prevent foreign objects in the water from hitting the detection component 300, thereby extending the service life of the detection component 300 and improving the reliability of the device. The water passage provided on the protection cavity 130 allows the water flow of the water body to enter the protection cavity 130 and contact the detection component 300, ensuring the accuracy of the data obtained by the detection component 300.

[0041] It can be understood that the wall surface of the protection cavity 130 is provided with a plurality of penetrating first through holes, and the plurality of first through holes constitute a water passage.

[0042] The water passage can be either a long strip opening or a plurality of first through holes. The first through hole can control its inner diameter to achieve a filtering effect, thereby preventing suspended matter in the water from entering the protective cavity 130 and affecting the operation of the detection component 300. Therefore, the water passage preferably has a structure of a plurality of first through holes.

[0043] Reference Figure 3 As shown, it can be understood that the outer wall of the protection cavity 130 is provided with a plurality of convex portions 131, each convex portion 131 is located between two adjacent first through holes, and the convex portion 131 extends in the opposite direction of the water inlet direction of the water passage.

[0044] Multiple convex parts 131 extend outward, and when a sheet-like object in the water floats and moves near the water passage, it can adhere to the convex parts 131. At this time, there is a gap between the sheet-like floating object and the water passage, and the gap distance is the extension length of the convex parts 131. The convex parts 131 can ensure that the water passage is not blocked, ensuring that the detection component 300 can work normally. If the convex parts 131 are not provided, the sheet-like floating object may move to the vicinity of the water passage, and the suction force of the water flow will cover the water passage, causing the water passage to be blocked.

[0045] It can be understood that the control component 200 includes a first traction member 210 and a second traction member 220, the first bucket portion 110 is connected to the first traction member 210 and the second traction member 220, and the second bucket portion 120 is also connected to the first traction member 210 and the second traction member 220, the first traction member 210 is configured to drive the first traction member 210 to move the first bucket portion 110 and the second bucket portion 120 to an open state, and the second traction member 220 is configured to drive the second traction member 220 to move the first bucket portion 110 and the second bucket portion 120 to a closed state.

[0046] Specifically, in some of the embodiments, it can be understood that the first traction member 210 includes a pair of flexible first traction ropes, the first bucket portion 110 and the second bucket portion 120 are respectively connected with the first traction rope, the connection point of the first traction rope and the first bucket portion 110 is away from the rotation axis of the first bucket portion 110 and away from the second bucket portion 120, and the connection point of the other first traction rope and the second bucket portion 120 is away from the rotation axis of the second bucket portion 120 and away from the first bucket portion 110.

[0047] When the first traction rope is pulled, the first traction rope pulls one end of the first bucket portion 110 and the second bucket portion 120 away from the rotation axis, that is, one end of the first bucket portion 110 and the second bucket portion 120 away from each other, so that the middle part moves downward due to gravity, thereby making the first bucket portion 110 and the second bucket portion 120 open outward and be in an open state.

[0048] It can be understood that the second traction member 220 includes a flexible second traction rope, a first wire passer 221 and a second wire passer 222. The first wire passer 221 is arranged at the hinge of the first bucket portion 110 and the second bucket portion 120, and the second wire passer 222 is arranged in the second bucket portion 120. The second wire passer 222 is away from the rotation axis of the second bucket portion 120 and close to the first bucket portion 110. The second traction rope passes through the first wire passer 221 and the second wire passer 222 in sequence and is connected to the first bucket portion 110. The connection point between the second traction rope and the first bucket portion 110 is away from the rotation axis of the first bucket portion 110 and close to the second bucket portion 120.

[0049] When the second traction rope is pulled, the second traction rope pulls the first bucket portion 110 and the second bucket portion 120 closer to each other, so that the first bucket portion 110 and the second bucket portion 120 are closed toward the middle and maintain the closed state.

[0050] When the grabbing bucket 100 is lowered, the first bucket part 110 and the second bucket part 120 can be opened and moved down to the bottom of the water body by releasing the first traction rope. When the grabbing bucket 100 reaches the bottom of the water body and contacts the bottom mud, the second traction rope is pulled again without applying force to the first traction rope. At this time, the second traction rope pulls the first bucket part 110 and the second bucket part 120 closer to each other, grabs the bottom mud and retains it in the accommodation cavity surrounded by the first bucket part 110 and the second bucket part 120.

[0051] It can be understood that the first wire passer 221 and the second wire passer 222 are both guide pulleys.

[0052] The first wire passer 221 and the second wire passer 222 can adopt a threading hole structure to allow the second traction rope to pass through the threading hole, but this is easy to wear the second traction rope, and the second traction rope is also easy to wear the threading hole. After the first wire passer 221 and the second wire passer 222 are replaced with a guide pulley, the friction between the second traction rope and the guide pulley is greatly reduced, which can extend the service life of the second traction rope and the guide pulley.

[0053] It is understandable that the walls of the first bucket portion 110 and the second bucket portion 120 are respectively provided with through holes 140 .

[0054] When the bottom mud is filled into the accommodation cavity surrounded by the first bucket 110 and the second bucket 120, there may be liquid on the top of the bottom mud between the bottom mud and the grabbing bucket 100, and the bottom mud is in a viscous state, which is easy to stick to the inner wall of the grabbing bucket 100 to form a closed chamber in the upper space, so that the liquid cannot be discharged. Therefore, a through hole 140 is opened on the wall surface of the first bucket 110 and the second bucket 120, so that the liquid can be discharged from the through hole 140, and only the bottom mud is retained in the accommodation cavity. It should be understood that a plurality of through holes 140 can be opened.

[0055] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
