Description

Technical Field

[0001] This utility model relates to the field of sediment content detection technology, and in particular to a sampling device for detecting sediment content in the bottom sediment of waterways. Background Technology

[0002] Waterways are channels opened up in waterways for the safe navigation of ships. They have a certain depth, width and curvature. The depth ensures that ships do not touch the bottom, the width provides navigation space, and the curvature facilitates turning. Waterways connect different regions, promote water transport, and ensure the efficient flow of goods and people. They are key infrastructure for water transportation and can also be used for the comprehensive utilization of water resources, playing an important role in economic development.

[0003] Sampling equipment for sediment content detection is a tool specifically designed for collecting sediment samples from the bottom of water bodies.

[0004] Its main function is to provide representative samples for sediment content detection. By analyzing these samples, parameters such as sediment content and particle size distribution in the water area can be understood, providing important data support for water conservancy project construction, waterway maintenance, and environmental monitoring.

[0005] When the sampler is in hard sediment or with gravel at the bottom, the grab bucket is prone to wear, which leads to a decrease in sampling efficiency. Therefore, it is necessary to inspect and replace the grab bucket regularly. However, traditional grab buckets are fixed by bolts, which requires special tools for disassembly. In addition, the tools require a certain amount of time and effort to use, which reduces the replacement efficiency. To solve the above problems, a sampling device for detecting sediment content in waterway bottom sediment is proposed. Utility Model Content

One end of the push rod 602 is fixedly connected to a horizontal plate 603, and the push rod 602 is fixed to the horizontal plate 603. When the push rod 602 moves, it can drive the horizontal plate 603 to move together. The end of the push rod 602 away from the horizontal plate 603 is fixedly connected to a push block 601, which is used to facilitate the movement of the push rod 602. Both the front and rear ends of the horizontal plate 603 are rotatably connected to rotating rods 604. The ends of the two rotating rods 604 away from the horizontal plate 603 are rotatably connected to movable plates 605. The rotating rods 604 are used to connect the horizontal plate 603. 3 is connected to the movable plate 605. When the horizontal plate 603 moves, it can drive the movable plate 605 to move together. Each of the two movable plates 605 is fixedly connected to a locking block 606 on the opposite side. The locking block 606 is connected to the movable plate 605. When the movable plate 605 moves, it can drive the locking block 606 to move together. The two locking blocks 606 are slidably connected inside the two locking slots 607 respectively. The left and right sides of the connecting block 10 are provided with locking slots 607. The locking slots 607 are used to cooperate with the locking blocks 606, so as to provide a limiting function for the connecting block 10. Each of the two movable plates 605 is provided with a reset component 7 on the opposite side.

[0037] Reference Figure 4The weighting component 8 includes multiple weight blocks 801, which are slidably connected to the inner top side of the grab bucket 1. The weight blocks 801 are used to increase the weight of the grab bucket 1. The weight blocks 801 are made of stainless steel. Trapezoidal blocks 802 are fixedly connected to the front and rear sides of the weight blocks 801. Multiple evenly distributed interlocking blocks 803 are fixedly connected to the inner top side of the grab bucket 1. Two trapezoidal blocks 802 are slidably connected to the interior of two interlocking blocks 803. The interlocking blocks 803 are used in conjunction with the trapezoidal blocks 802. The interior of the interlocking block 803 and the outer periphery of the trapezoidal block 802 are both trapezoidal. Two fixing blocks 901 are slidably connected to the front and rear sides of the weight blocks 801.

[0038] Reference Figure 5 The fixing component 9 includes two limiting plates 904, which are slidably connected to the front and rear sides of the inner side of the interlocking block 803, respectively. A spring 903 is fixedly connected to the opposite side of each of the two limiting plates 904. The limiting plates 904 apply pressure to the springs 903, which provide a reset thrust. The springs 903 are made of spring steel, specifically 65Mn spring steel. A fixing rod 902 is fixedly connected to the opposite side of each of the two limiting plates 904. A fixing block 901 is fixedly connected to the opposite end of each of the two fixing rods 902. The fixing rod 902 connects the fixing block 901 to the limiting plates 904, and can move the limiting plates 904 together when the fixing block 901 moves. The end of the spring 903 away from the limiting plates 904 is fixedly connected to the inside of the grab bucket 1, and the fixing rod 902 is slidably connected to the inside of the interlocking block 803.

[0039] Reference Figure 3 The reset assembly 7 includes a support rod 701, which is slidably connected to one side of the movable plate 605. A compression spring 702 is fixedly connected to one side of the movable plate 605. The compression spring 702 is sleeved on the outer periphery of the support rod 701. The support rod 701 is used to guide the movement of the movable plate 605 so that the movable plate 605 always remains horizontal.

[0040] Working principle: When in use, first install the grab bucket 1 and the mounting block 2. By pressing the push rod 602, the push block 601 is moved. When the push block 601 moves, the two rotating rods 604 rotate in opposite directions, thereby driving the two movable plates 605 to move. The two movable plates 605 will move in opposite directions along the two support rods 701 and squeeze the compression spring 702. Then, insert the connecting block 10 at the top of the grab bucket 1 into the mounting block 2. After that, the push rod 602 can be released. After the push rod 602 is released, the compression spring 702 loses the pressure of the movable plate 605 and thus generates a reset movement, and then slides into the slot 607 to provide a limiting effect on the connecting block 10, so that the grab bucket 1 and the mounting block 2 are installed.

[0041] Subsequently, based on the required water flow velocity, select and install the appropriate number of weight blocks 801. By moving the fixed block 901, the fixed block 901 will drive the fixed rod 902 to move together. When the fixed rod 902 moves, it will drive the limiting plate 904 to move together and compress the spring 903. Then, align the trapezoidal blocks 802 on the left and right sides of the weight block 801 with the inside of the fitting block 803, so that the trapezoidal blocks 802 are embedded in the fitting block 803. The weight block 801 can then be installed in the grab bucket 1. After that, the fixed block 901 can be released. Through the reset movement of the spring 903, the limiting plate 904 is pushed to move, so that the fixed rod 902 drives the fixed block 901 to move. Thus, the fixed block 901 contacts the weight block 801, and the weight block 801 can be fixed in the grab bucket 1, thereby completing the weight increase.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
