[0002] Water sampling devices are a type of sampling equipment commonly used in sample collection. They are typically used to collect samples from various water sources. After the water source is sampled, it is tested to determine the level of environmental pollution and environmental quality.
[0003] Floating debris in water bodies is usually unevenly distributed. Floating debris around the sampling device may not be able to accumulate sufficiently near the sampling port, resulting in a discrepancy between the floating debris content in the collected sample and the actual content in the water body, thus failing to accurately reflect the overall situation of floating debris in the water body. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable-depth layered sampling device to solve at least one of the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable depth layered sampling device, comprising a main body, the main body further comprising a disturbance mechanism and a sampling mechanism, an electric telescopic rod fixedly connected to the top of the main body, a fixed plate fixedly connected to the end of the electric telescopic rod away from the main body, and a rotating rod rotatably connected to the outer wall of the main body, the rotating rod passing through the main body and rotatably connected to the main body.
[0006] Preferably, circular blocks are fixedly connected to the left and right ends of the rotating rod, and several impellers are fixedly connected to the outer walls of the two circular blocks respectively. A circular plate is fixedly connected to the outer wall of the rotating rod, and two protrusions are fixedly connected to the outer wall of the circular plate.
[0007] Preferably, a slide rod is slidably connected to the inner wall of the main body, the end of the slide rod away from the contact block extends to the outside of the main body and is slidably connected to the main body, and the end of the slide rod near the circular plate is fixedly connected to the contact block.
[0008] Preferably, a disturbance plate is fixedly connected to the extension end of the slide rod, and a spring is fixedly connected to the side wall of the contact block, with the end of the spring away from the contact block being fixedly connected to the inner wall of the main body.
[0009] Preferably, the top of the main body has two sampling ports, the top of the main body is fixedly connected to a shell, the top of the main body is fixedly connected to an electric telescopic rod II, and the end of the electric telescopic rod II away from the main body is fixedly connected to a push plate.
[0010] Preferably, a connecting rod is slidably connected to the outer wall of the housing, a sealing plate is fixedly connected to the end of the connecting rod away from the housing, and the end of the connecting rod away from the sealing plate extends into the housing and is slidably connected to the housing.
[0011] Preferably, a connecting block is fixedly connected to the extension end of the connecting rod, a strip plate is rotatably connected to the side of the connecting block away from the connecting rod, the side of the strip plate away from the connecting block is rotatably connected to the push plate, and a sampling tube is fixedly connected to the bottom of the main body, with a sealing cap threaded to the bottom end of the sampling tube.
[0012] The beneficial effects of this utility model are as follows:
[0013] In this utility model:
[0014] 1. When using this device for sampling, first fix the device at the designated sampling location using the fixing plate, then activate the electric telescopic rod. The electric telescopic rod will lower the main body to the designated depth. When the main body descends into the river water, several impellers will be affected by the river flow, causing them to rotate. The rotation of the impellers will drive the rotating rod and the circular plate to rotate. During the rotation of the circular plate, the protrusion will rotate and contact the contact block. At this time, the contact block will drive the sliding rod and the disturbance plate to move outward. The outward movement of the disturbance plate will disturb the water area around the main body, making it easier for floating objects in the water to drift towards the device. This will make the sample collected more representative. The device, by disturbing the surrounding water area through the disturbance plate, simulates the state of natural water flow to a certain extent, making the sampling environment closer to the real situation. The physical, chemical, and biological characteristics of the collected sample will better reflect the actual condition of the water body, which is beneficial for subsequent accurate analysis and research of the sample.
[0015] 2. After the electric telescopic rod one moves the main body to the designated position, the electric telescopic rod two is activated. The electric telescopic rod two moves the push plate upward. During the upward movement, the push plate moves the connecting rod towards the electric telescopic rod two through the strip plate, thereby causing the connecting rod to move the sealing plate away from above the sampling port. At this time, a gap is formed directly between the sampling port and the sealing plate. Water in the water area enters the main body through the gap for collection and sampling. The movement of the sealing plate is controlled by the action of the electric telescopic rod two, which can accurately select the sampling time after the main body reaches the designated position. The sampling port will only be opened when the device is accurately placed at the desired sampling depth and position, ensuring that the collected water sample comes from a specific target area. This avoids premature sampling during the descent of the device or before reaching the designated position, thereby improving the accuracy and reliability of sampling. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides, for example Figure 1-5The adjustable-depth stratified sampling device shown includes a main body 101, which further includes a disturbance mechanism 1 and a sampling mechanism 2. An electric telescopic rod 102 is fixedly connected to the top of the main body 101. A fixing plate 103 is fixedly connected to the end of the electric telescopic rod 102 away from the main body 101. A rotating rod 104 is rotatably connected to the outer wall of the main body 101, passing through and rotatably connected to the main body 101. Circular blocks 105 are fixedly connected to the left and right ends of the rotating rod 104, respectively. Several impellers 106 are fixedly connected to the outer walls of the two circular blocks 105. A circular plate 107 is fixedly connected to the outer wall of the moving rod 104. Two protrusions 108 are fixedly connected to the outer wall of the circular plate 107. A sliding rod 109 is slidably connected to the inner wall of the main body 101. The end of the sliding rod 109 away from the contact block 110 extends to the outside of the main body 101 and is slidably connected to the main body 101. The end of the sliding rod 109 near the circular plate 107 is fixedly connected to the contact block 110. A disturbance plate 111 is fixedly connected to the extended end of the sliding rod 109. A spring 112 is fixedly connected to the side wall of the contact block 110. The end of the spring 112 away from the contact block 110 is fixedly connected to the inner wall of the main body 101.
[0024] When sampling is required, the device is first fixed at the designated sampling location using the fixing plate 103. Then, the electric telescopic rod 102 is activated, causing the main body 101 to descend to the designated depth. When the main body 101 descends into the river water, several impellers 106 are affected by the river flow, causing them to rotate. The rotation of the impellers 106 drives the rotating rod 104 and the circular plate 107 to rotate. During the rotation of the circular plate 107, the protrusion 108 rotates, and during the rotation of the protrusion 108, it contacts the contact block 11. At zero contact, the contact block 110 drives the slide rod 109 and the disturbance plate 111 to move outward. After the disturbance plate 111 moves outward, it can disturb the water area around the main body 101, making it easier for floating objects in the water to drift towards the device. This makes the samples collected during sampling more representative. The device disturbs the surrounding water area through the disturbance plate 111, which to some extent simulates the state of natural water flow, making the sampling environment closer to the real situation. The physical, chemical and biological characteristics of the collected samples can better reflect the actual condition of the water body, which is conducive to the accurate analysis and research of the samples in the future.
[0025] Two sampling ports 201 are provided on the top of the main body 101. A housing 202 is fixedly connected to the top of the main body 101. An electric telescopic rod 203 is fixedly connected to the top of the main body 101. A push plate 204 is fixedly connected to the end of the electric telescopic rod 203 away from the main body 101. A connecting rod 205 is slidably connected to the outer wall of the housing 202. A sealing plate 206 is fixedly connected to the end of the connecting rod 205 away from the housing 202. The end of the connecting rod 205 away from the sealing plate 206 extends into the housing 202 and is slidably connected to the housing 202. A connecting block 207 is fixedly connected to the extended end of the connecting rod 205. A strip plate 208 is rotatably connected to the side of the connecting block 207 away from the connecting rod 205. The side of the strip plate 208 away from the connecting block 207 is rotatably connected to the push plate 204. A sampling tube 209 is fixedly connected to the bottom of the main body 101. A sealing cap 210 is threadedly connected to the bottom end of the sampling tube 209.
[0026] After the electric telescopic rod 102 moves the main body 101 to the designated position, the electric telescopic rod 203 is activated. The electric telescopic rod 203 moves the push plate 204 upward. During the upward movement, the push plate 204 moves the connecting rod 205 towards the electric telescopic rod 203 via the strip plate 208. This causes the connecting rod 205 to move the sealing plate 206 away from the sampling port 201. At this time, a gap is formed between the sampling port 201 and the sealing plate 206. Water in the water enters the main body 101 through the gap for collection and sampling. The movement of the sealing plate 206 is controlled by the action of the electric telescopic rod 203. This allows for precise selection of the sampling time after the main body 101 reaches the designated position. The sampling port 201 will only open when the device is accurately placed at the desired sampling depth and position, ensuring that the collected water sample comes from a specific target area. This avoids premature sampling during the descent of the device or before reaching the designated position, thereby improving the accuracy and reliability of the sampling.
[0027] The working principle of the adjustable depth stratified sampling device provided by this utility model is as follows: When it is necessary to use the device for sampling, the device is first fixed at the designated sampling position by the fixing plate 103, and then the electric telescopic rod 102 is started. The electric telescopic rod 102 drives the main body 101 to descend to the designated depth position. When the main body 101 descends into the river water, several impellers 106 are affected by the river water flow, thereby forcing several impellers 106 to rotate. After the several impellers 106 rotate, they drive the rotating rod 104 and the circular plate 107 to rotate. During the rotation of the circular plate 107, it drives the protrusion 108 to rotate. During the rotation of the protrusion 108, it contacts the contact block 110. At this time, the contact block 110 drives the sliding rod 109 and the disturbance plate 111 to move outward. After the disturbance plate 111 moves outward, it can disturb the water area around the main body 101, making it easier for floating objects in the water to drift to the device, so that the sample collected during sampling is more representative.
[0028] When the electric telescopic rod 102 moves the main body 101 to the designated position, the electric telescopic rod 203 is activated. The electric telescopic rod 203 moves the push plate 204 upward. During the upward movement, the push plate 204 moves the connecting rod 205 towards the electric telescopic rod 203 via the strip plate 208. This causes the connecting rod 205 to move the sealing plate 206 away from the sampling port 201. At this time, the sampling port 201 and the sealing plate 206 directly form a gap, and the water in the water area enters the main body 101 through the gap for collection and sampling.
[0029] Compared with related technologies, the adjustable-depth stratified sampling device provided by this utility model has the following beneficial effects:
[0030] This utility model provides an adjustable-depth stratified sampling device. When sampling is required, the device is first fixed at the designated sampling position using a fixing plate 103. Then, the electric telescopic rod 102 is activated, which lowers the main body 101 to the designated depth. When the main body 101 descends into the river water, several impellers 106 are affected by the river water flow, causing them to rotate. The rotation of the impellers 106 drives the rotating rod 104 and the circular plate 107 to rotate. During the rotation of the circular plate 107, the protrusion 108 rotates. During rotation, it comes into contact with the contact block 110. At this time, the contact block 110 drives the slide rod 109 and the disturbance plate 111 to move outward. After the disturbance plate 111 moves outward, it can disturb the water area around the main body 101, making it easier for floating objects in the water to drift towards the device. This makes the samples collected during sampling more representative. The device disturbs the surrounding water area through the disturbance plate 111, which to a certain extent simulates the state of natural water flow, making the sampling environment closer to the real situation. In this way, the physical, chemical and biological characteristics of the collected samples can better reflect the actual condition of the water body, which is conducive to the accurate analysis and research of the samples in the future.
[0031] After the electric telescopic rod 102 moves the main body 101 to the designated position, the electric telescopic rod 203 is activated. The electric telescopic rod 203 moves the push plate 204 upward. During the upward movement, the push plate 204 moves the connecting rod 205 towards the electric telescopic rod 203 via the strip plate 208. This causes the connecting rod 205 to move the sealing plate 206 away from the sampling port 201. At this time, a gap is formed between the sampling port 201 and the sealing plate 206. Water in the water enters the main body 101 through the gap for collection and sampling. The movement of the sealing plate 206 is controlled by the action of the electric telescopic rod 203. This allows for precise selection of the sampling time after the main body 101 reaches the designated position. The sampling port 201 will only open when the device is accurately placed at the desired sampling depth and position, ensuring that the collected water sample comes from a specific target area. This avoids premature sampling during the descent of the device or before reaching the designated position, thereby improving the accuracy and reliability of the sampling.
