Description

Technical Field

[0001] This utility model relates to the field of sampling, and in particular to a sampling device for water pollution detection. Background Technology

[0002] Sampling devices are equipment used to collect samples from substances or the environment, and are widely used in environmental monitoring, industrial production, scientific research experiments and other fields.

[0003] During water pollution testing, a sampling container is lowered into the water source using a rope. Pulling the rope opens a valve on the container, allowing water to enter and collect the sample. However, when sampling deeper areas, the container may not sink stably due to buoyancy, affecting the effectiveness of the sampling device. Utility Model Content

[0004] The technical problem this invention aims to solve is that when sampling water in deeper areas, the sampling bucket cannot sink stably into the deeper water source due to the buoyancy of the water, which affects the effectiveness of the sampling device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sampling device for water pollution detection, including a sampling bucket, a rope on one side of the sampling bucket, a piston at the upper end of the sampling bucket, a pull rope at the piston, and an adjustment device at the bottom of the sampling bucket, the adjustment device adjusting the weight of the sampling bucket through an adjustment block.

[0006] The effect achieved by the above components is as follows: when conducting water pollution detection, the weight of the sampling bucket is adjusted using an adjustment device so that the sampling bucket can reach a suitable depth at the water source. Then, the sampling bucket is lowered into the water source at a suitable depth by a rope. By pulling the rope, the piston on the sampling bucket is opened, and water enters the sampling bucket, completing the sampling.

[0007] Preferably, the adjustment device includes a placement block, a locking block, several adjustment blocks, and a control frame. The placement block is located at the bottom of the sampling barrel, the locking block is inserted into one side of the placement block, several adjustment blocks are inserted into the placement block, one side of the locking block is engaged with several adjustment blocks, and the control frame is located on one side of the adjustment blocks.

[0008] The effect achieved by the above components is as follows: When using the adjustment device, several adjustment blocks can be moved by a control frame fixed on one side of several adjustment blocks, so that the adjustment blocks are inserted into the placement block fixed at the bottom of the sampling bucket, thereby adjusting the weight of the sampling bucket. Then, the locking block is moved so that it passes through the placement block and engages with the adjustment block to fix the position of the adjustment block inside the placement block. By using the adjustment device, the weight of the sampling bucket can be adjusted so that the sampling bucket can reach a suitable depth at the water source, avoiding the situation where the sampling bucket cannot sink stably into a deeper water source due to the buoyancy of the water, thereby improving the effectiveness of the sampling device.

[0009] Preferably, the placement block is provided with a limiting component on the side near the card block to limit and block the card block.

[0010] Preferably, the limiting component includes a fixed plate, a baffle, and a spring. The fixed plate is located on the side of the placement block closer to the locking block. The baffle is inserted into one side of the fixed plate to block the locking block. The two ends of the spring are connected to the fixed plate and the baffle to reset the baffle.

[0011] The effect achieved by the above components is as follows: When using the locking block, first move the baffle so that the baffle slides inside the fixed plate fixed on one side of the block. At this time, the spring fixed to the baffle and the fixed plate deforms. Then, after the locking block engages with the adjusting block, release the baffle so that the spring returns to its original position, thereby driving the baffle to the side of the locking block to block and limit the locking block, preventing the locking block from detaching from the adjusting block.

[0012] Preferably, a telescopic rod is sleeved inside the spring, and both ends of the telescopic rod are connected to a fixed plate and a baffle.

[0013] The effect achieved by the above components is as follows: the telescopic rod is connected to the fixed plate and the baffle at both ends, and the telescopic rod is located inside the spring. The telescopic rod then restricts the shape of the spring, preventing the spring from bending and affecting its use.

[0014] Preferably, a connecting rope is provided on one side of the card block, and the connecting rope is connected to the placement block on the side away from the card block.

[0015] The effect achieved by the above components is to connect the card block and the placement block by connecting the two ends of the connecting rope, thereby preventing the card block from being lost.

[0016] Preferably, the side of the placement block away from the sampling bucket is provided with a rubber pad to increase the friction on one side of the placement block.

[0017] The effect achieved by the above-mentioned components is to make better contact between the placement block and the ground by fixing it to the side away from the sampling bucket with a rubber pad, thereby improving the effectiveness of the placement block.

[0018] Preferably, the side of the locking block away from the connecting rope has an auxiliary block, and the size of the auxiliary block on the side away from the locking block is smaller than the size on the other side.

[0019] The effect achieved by the above components is as follows: by fixing the auxiliary block on the side of the locking block away from the connecting rope, and by making the auxiliary block smaller on the side away from the locking block, the size of the locking block on the side is reduced, thus making it easier for the locking block to pass through the placement block and the adjustment block for locking and fixing.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] By using an adjustment device, the weight of the sampling bucket can be adjusted so that the sampling bucket can reach the appropriate depth at the water source. This avoids the situation where the sampling bucket cannot sink stably into the deeper water source due to the buoyancy of the water, thereby improving the effectiveness of the sampling device.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Figures 1 to 4 The sampling device for water pollution detection shown includes a sampling bucket 1, a rope 2 on one side of the sampling bucket 1, a piston 3 at the upper end of the sampling bucket 1, a pull rope 4 at the piston 3, and an adjustment device 5 at the bottom of the sampling bucket 1. The adjustment device 5 adjusts the weight of the sampling bucket 1 via an adjustment block 53. During water pollution detection, the adjustment device 5 is used to adjust the weight of the sampling bucket 1 so that it reaches a suitable depth at the water source. Then, the rope 2 is used to lower the sampling bucket 1 to the appropriate depth inside the water source. Finally, the pull rope 4 opens the piston 3 on the sampling bucket 1, allowing water to enter the sampling bucket 1, thus completing the sampling.

[0031] Figures 1 to 4 The adjustment device 5 shown includes a placement block 51, a locking block 52, several adjustment blocks 53 and a control frame 54. The placement block 51 is located at the bottom of the sampling barrel 1. The locking block 52 is inserted into one side of the placement block 51. Several adjustment blocks 53 are inserted into the placement block 51. One side of the locking block 52 is engaged with several adjustment blocks 53. The control frame 54 is located on one side of the adjustment blocks 53. When using the adjustment device 5, several adjustment blocks 53 can be moved by the control frame 54 fixed on one side of the adjustment block 53, so that the adjustment block 53 is inserted into the placement block 51 fixed at the bottom of the sampling bucket 1, and the weight of the sampling bucket 1 is adjusted. Then, the locking block 52 is moved so that the locking block 52 passes through the placement block 51 and locks and fixes with the adjustment block 53, thus fixing the position of the adjustment block 53 inside the placement block 51. By using the adjustment device 5, the weight of the sampling bucket 1 can be adjusted, so that the sampling bucket 1 can reach a suitable depth at the water source, avoiding the situation where the sampling bucket 1 cannot sink stably into a deeper water source due to the buoyancy of the water, thereby improving the use effect of the sampling device.

[0032] Figures 1 to 4The placement block 51 shown is provided with a limiting component 55 on the side near the locking block 52 to limit and block the locking block 52. The limiting component 55 includes a fixing plate 551, a baffle 552 and a spring 553. The fixing plate 551 is located on the side of the placement block 51 near the locking block 52. The baffle 552 is inserted into one side of the fixing plate 551 to block the locking block 52. The two ends of the spring 553 are connected to the fixing plate 551 and the baffle 552 to reset the baffle 552. When using the locking block 52, first move the baffle 552 so that it slides inside the fixing plate 551 fixed to one side of the placement block 51. At this time, the spring 553, which is fixed to the baffle 552 and the fixing plate 551, deforms. Then, after the locking block 52 engages with the adjusting block 53, release the baffle 552 so that the spring 553 returns to its original position, thereby moving the baffle 552 to one side of the locking block 52 to block and limit the locking block 52, preventing it from detaching from the adjusting block 53. A telescopic rod 554 is sleeved inside the spring 553, with both ends of the telescopic rod 554 connected to the fixing plate 551 and the baffle 552. The telescopic rod 554, located inside the spring 553, restricts the shape of the spring 553, preventing it from bending and affecting its use.

[0033] Figures 1 to 4 The shown card block 52 has a connecting rope 56 on one side, and the side of the connecting rope 56 away from the card block 52 is connected to the placement block 51. The card block 52 and the placement block 51 are connected by connecting the two ends of the connecting rope 56 to the card block 52 and the placement block 51, so as to avoid the card block 52 from being lost.

[0034] Figures 1 to 4 The placement block 51 shown has a rubber pad 57 on the side away from the sampling container 1 to increase the friction on that side. The rubber pad 57 is fixed to the side of the placement block 51 away from the sampling container 1, allowing the placement block 51 to better contact the ground, thus improving its usability. The locking block 52 has an auxiliary block 58 on the side away from the connecting rope 56. The auxiliary block 58 is smaller on the side away from the locking block 52 than on the other side. By fixing the auxiliary block 58 to the side of the locking block 52 away from the connecting rope 56, and by making the auxiliary block 58 smaller on the side away from the locking block 52, the size of the locking block 52 is reduced, making it easier for the locking block 52 to pass through the placement block 51 and engage with the adjusting block 53.

[0035] Working Principle: During water pollution detection, the adjustment device 5 is used to adjust the weight of the sampling bucket 1, allowing it to reach a suitable depth at the water source. Then, the sampling bucket 1 is lowered into the water source at the appropriate depth via the rope 2. Pulling the rope 4 opens the piston 3 on the sampling bucket 1, allowing water to enter and completing the sampling. When using the adjustment device 5, several adjustment blocks 53 are moved via a control frame 54 fixed to one side, inserting them into the placement block 51 fixed at the bottom of the sampling bucket 1. This adjusts the weight of the sampling bucket 1. Then, the locking block 52 is moved, engaging and securing the adjustment block 53 through the placement block 51, thus fixing the adjustment block 53 in its position within the placement block 51. By using the adjustment device 5, the weight of the sampling bucket 1 can be adjusted, ensuring it reaches a suitable depth at the water source. This prevents the sampling bucket 1 from failing to sink stably into deeper water due to buoyancy, thereby improving the effectiveness of the sampling device.

[0036] When using the locking block 52, first move the baffle 552 so that it slides inside the fixing plate 551 fixed on one side of the placement block 51. At this time, the spring 553 fixed to the baffle 552 and the fixing plate 551 deforms. Then, after the locking block 52 engages with the adjusting block 53, release the baffle 552 so that the spring 553 returns to its original position, thereby driving the baffle 552 to the side of the locking block 52 to block and limit the locking block 52, preventing the locking block 52 from disengaging from the adjusting block 53.
