Description

Technical Field

[0001] This utility model relates to the field of water sample uniform separation technology, specifically a water sample uniform separation device. Background Technology

[0002] As my country's requirements for the ecological environment are gradually increasing, water monitoring equipment is essential to prevent illegal enterprises from illegally discharging wastewater, whether in urban rivers, lakes, or rivers.

[0003] Existing water sample uniform distribution devices collect water from the river channel beforehand using a collection device. For example, a floating, timed automatic water sampling device (application number: 202121778255.2) includes a float, a test tube rack, a sampling tube, a dispensing tube, and an electrical control unit. The sampling tube is vertically connected to the middle of the float, and the test tube rack is fixed to the outer circumferential wall of the sampling tube on the top surface of the float. The bottom of the sampling tube extends into the water and is fixed with a spherical filter screen. An electrical control power supply is installed inside the sampling tube, and the top of the sampling tube is rotatably connected to the dispensing tube. The electrical control unit regulates the connection between the sampling tube and the dispensing tube and provides rotational power to the dispensing tube. This sampling device can dynamically float and time the current water sample, and can select various sampling methods such as anchoring to the bank or drifting with the water as needed. It has a simple structure and is easy to implement.

[0004] However, existing water sample homogenization devices lack certain protective devices during the process of homogenizing the collected water samples. When operating outdoors or in environments with many impurities in the air, the homogenized water samples are contaminated by impurities in the air, affecting the subsequent water sample test results. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water sample uniform separation device, which solves the problem that in the process of uniformly separating collected water samples, there is a lack of protective devices. When operating outdoors or in environments with many air impurities, the separated water samples are contaminated by air impurities, affecting the subsequent water sample test results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water sample uniform dispensing device, comprising a sample container, a water pump fixedly connected to the top of the sample container by bolts, an electric metering valve installed at the output end of the water pump, the other end of the electric metering valve connected to a delivery pipe, a movable disc rotatably connected to the outer wall of the sample container via a sealed bearing, a sealing device provided above the movable disc, the sealing device comprising: mounting components, multiple of which are fixedly connected to the top of the movable disc in a ring at equal intervals; and a dispensing container placed on the sample container. The device comprises: a top part; a connecting pipe threaded to the inner wall of the separating tank; a pressure relief valve installed on the outer wall of the connecting pipe; four rubber gaskets, with their far sides fixedly connected to the inner wall of the connecting pipe and their near sides abutting against each other; a first magnet fixedly connected to the top of the connecting pipe; and a drive unit located below the movable disc. The device is used to install the separating tank, the connecting pipe to install the pressure relief valve, rubber gaskets, and the first magnet, the rubber gaskets ensuring the sealing of the connecting pipe, and the drive unit causing the movable disc to rotate.

[0007] Preferably, the driving unit includes: a base disposed below the movable disk; a first servo motor fixedly connected to the top of the inner wall of the base, and its output end fixedly connected to the bottom of the movable disk; and a limiting unit disposed inside the base; wherein the base mounts the first servo motor and the limiting unit, and the output end of the first servo motor drives the movable disk to rotate.

[0008] Preferably, the limiting unit includes: an annular groove formed at the top of the base; and a limiting rod, the top of which is fixedly connected to the bottom of the movable disc, and the bottom of which is movably connected to the inner wall of the annular groove; wherein, the cooperation of the annular groove and the limiting rod makes the rotation of the movable disc more stable.

[0009] Preferably, a correction mechanism is provided on the outside of the delivery pipe. The correction mechanism includes: a flexible hose connected to the end of the delivery pipe away from the electric metering valve; a first magnet installed at the end of the flexible hose away from the delivery pipe; and a second magnet installed at the top of the connecting pipe. The first magnet and the second magnet work together to ensure that the output end of the flexible hose corresponds to the top of the connecting pipe.

[0010] Preferably, the sample container is provided with a mixing unit, which includes: a second servo motor, fixedly connected to the top of the sample container, and its output end passing through the top of the sample container through a sealed bearing; and a stirring rod, fixedly connected to the output end of the second servo motor; wherein the output end of the second servo motor drives the stirring rod to stir and mix the water sample, so that the water sample inside the separatory container is uniform.

[0011] Beneficial effects

[0012] This invention provides a water sample uniform distribution device. It offers the following advantages: Through the cooperation of the distribution bucket, rubber pad, and connecting pipe, when the water sample collected inside the bucket is uniformly distributed via an electric metering valve, the water sample flowing into the connecting pipe exerts pressure on the rubber pad, creating a gap on one side of the rubber pad that allows water to flow into the distribution bucket. Once a certain volume of water is reached in one distribution bucket, no more water sample flows in. At this point, the rubber pad returns to its original position due to its elasticity, ensuring that the water sample inside the distribution bucket is not contaminated by airborne impurities, thus guaranteeing the accuracy of subsequent water sample testing data.

[0013] Through the cooperation of the hose, the first magnet, and the second magnet, the movable disc is driven to rotate by the output of the first servo motor, causing each dispensing bucket to rotate in turn to the position below the first magnet. When the dispensing bucket is rotated by the movable disc, through the cooperation of the first magnet and the second magnet, the first magnet can be attracted to the second magnet at the top of the connecting tube with each rotation of the dispensing bucket. Furthermore, when there is an error in the rotation of the first servo motor, the hose can correct the error, ensuring that the water sample can completely enter the interior of the dispensing bucket.

[0019] 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.

[0020] Existing water sample homogenization devices lack adequate protection during the homogenization process of collected water samples. When operating outdoors or in environments with high levels of airborne impurities, the homogenized water samples can become contaminated by these airborne contaminants, affecting subsequent water sample testing results.

[0021] In view of this, the present invention provides a water sample uniform distribution device. Through the cooperation between the distribution bucket, the rubber pad, and the connecting tube, when the water sample collected inside the sample bucket is uniformly distributed through the electric metering valve, the water sample will exert pressure on the rubber pad as it flows into the connecting tube, causing a gap to appear on the side where the rubber pads are in contact with each other. Water can then flow into the interior of the distribution bucket. When a certain amount of water is reached in a distribution bucket, no more water sample will flow in. At this time, the rubber pad can be reset by its own elasticity, ensuring that the water sample inside the distribution bucket is not contaminated by impurities in the air, thus ensuring the authenticity of the subsequent water sample test data.

[0022] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0023] Example 1: By Figures 1 to 4It is known that a water sample uniform separation device includes a sample container 1. A water pump 11 is bolted to the top of the sample container 1. An electric metering valve 12 is installed at the output end of the water pump 11, and the other end of the electric metering valve 12 is connected to a delivery pipe 13. A controller 14 is installed on the front of the sample container 1. A movable disc 15 is rotatably connected to the outer wall of the sample container 1 via a sealed bearing. A sealing device 2 is provided above the movable disc 15. The sealing device 2 includes: mounting parts 21, multiple of which are fixedly connected to the top of the movable disc 15 in a ring at equal intervals; separation A container 22 is placed on top of the mounting component 21; a connecting pipe 23 is threaded to the inner wall of the separating container 22; a pressure relief valve 24 is installed on the outer wall of the connecting pipe 23; four rubber gaskets 25 are provided, with their far sides fixedly connected to the inner wall of the connecting pipe 23, and their close sides fitting together; wherein, the mounting component 21 is used to install the separating container 22, the connecting pipe 23 is used to install the pressure relief valve 24, the rubber gaskets 25 and the first magnet 32, the rubber gaskets 25 ensure the sealing of the connecting pipe 23, and the movable disc 15 is rotated by the drive unit 26;

[0024] In the specific implementation process, it is worth noting that the models of the water pump 11, controller 14, and electric metering valve 12 are not specifically limited. The controller 14 controls the electric metering valve 12 to achieve uniform separation of the water sample. The fitting relationship between the mounting part 21 and the top and bottom of the separating tank 22 allows for easy removal of the separating tank 22. Through the action of the pressure relief valve 24, as the water sample continuously flows into the separating tank 22, the internal pressure gradually increases. The pressure relief valve 24 can be manually opened to release the pressure. The connecting pipe 23 is threadedly connected to the separating tank 22. When it is necessary to remove the water from the separating tank 22, the connecting pipe 23 can be unscrewed. The water sample is poured out, and there is a sealing gasket or other sealing mechanism between the connecting tube 23 and the dispensing tank 22 to ensure that there is no leakage. When the water sample collected in the sample tank 1 is evenly distributed through the electric metering valve 12, the water sample will exert pressure on the rubber pad 25 when it flows into the connecting tube 23, causing a gap to appear on the side of the rubber pad 25 that is in contact with each other, so that the water can flow into the dispensing tank 22. When a certain amount of water is reached in a dispensing tank 22, no more water sample will flow in. At this time, the rubber pad 25 can be reset by its own elasticity, ensuring that the water sample in the dispensing tank 22 is not contaminated by impurities in the air, and ensuring the authenticity of the water sample test data in the later stage.

[0025] Furthermore, the drive unit 26 includes: a base 261 disposed below the movable disk 15; a first servo motor 262 fixedly connected to the top of the inner wall of the base 261, and its output end fixedly connected to the bottom of the movable disk 15; and a limiting unit 263 disposed inside the base 261; wherein the base 261 mounts the first servo motor 262 and the limiting unit 263, and the output end of the first servo motor 262 drives the movable disk 15 to rotate;

[0026] In the specific implementation process, it is worth noting that when performing uniform liquid distribution, the controller 14 controls the output end of the first servo motor 262 to rotate indirectly, driving the movable disk 15 to rotate indirectly, in conjunction with the electric metering valve 12, to complete the uniform liquid distribution work.

[0027] Furthermore, the limiting unit 263 includes: an annular groove 2631, which is formed on the top of the base 261; and a limiting rod 2632, which is fixedly connected to the bottom of the movable plate 15 at the top and movably connected to the inner wall of the annular groove 2631 at the bottom; wherein, through the cooperation of the annular groove 2631 and the limiting rod 2632, the movable plate 15 rotates more stably.

[0028] In the specific implementation process, it is worth noting that when the movable plate 15 rotates, the limiting rod 2632 rotates on the inner wall of the annular groove 2631 to ensure the rotation stability of the movable plate 15. In addition, ball bearings are provided on the side of the limiting rod 2632 that is in contact with the base 261 and at the bottom to ensure the stability of the limiting rod 2632.

[0029] Specifically, when using this water sample uniform distribution device, when the water sample collected inside the sample bucket 1 is uniformly distributed through the electric metering valve 12, the water sample will exert pressure on the rubber pad 25 as it flows into the connecting pipe 23, causing a gap to appear on the side where the rubber pads 25 are in contact with each other, allowing water to flow into the distribution bucket 22. When a certain amount of water is reached inside a distribution bucket 22, no more water sample will flow in. At this time, the rubber pad 25 can reset itself through its own elasticity, ensuring that the water sample inside the distribution bucket 22 is not contaminated by impurities in the air, thus ensuring the authenticity of the water sample test data in the later stage. When uniform distribution is performed, the controller 14 controls the output end of the first servo motor 262 to rotate indirectly, driving the movable disk 15 to rotate indirectly, which works in conjunction with the electric metering valve 12 to complete the uniform distribution work.

[0030] Example 2: From Figure 1-4It is known that a correction mechanism 3 is provided on the outside of the conveying pipe 13. The correction mechanism 3 includes: a flexible hose 31 connected to the end of the conveying pipe 13 away from the electric metering valve 12; a first magnet 32 ​​installed at the end of the flexible hose 31 away from the conveying pipe 13; and a second magnet 33 installed at the top of the connecting pipe 23. The first magnet 32 ​​and the second magnet 33 are used to ensure that the output end of the flexible hose 31 corresponds to the top of the connecting pipe 23.

[0031] In the specific implementation process, it is worth noting that the surfaces where the first magnet 32 ​​and the second magnet 33 are in contact are fitted with sealing gaskets to ensure that the water flow will not leak when water flows. The first magnet 32 ​​and the second magnet 33 are ring magnets. After the two are magnetically connected, the hose 31 and the connecting pipe 23 are connected. The movable disk 15 is driven to rotate by the output end of the first servo motor 262, so that each dispensing tank 22 rotates in turn to the bottom of the first magnet 32. When the dispensing tank 22 is driven to rotate by the movable disk 15, through the cooperation between the first magnet 32 ​​and the second magnet 33, the first magnet 32 ​​can be attracted to the second magnet 33 at the top of the connecting pipe 23 with each rotation of the dispensing tank 22. Furthermore, when there is an error in the rotation of the first servo motor 262, the hose 31 can correct the error, ensuring that the water sample can completely enter the interior of the dispensing tank 22.

[0032] Furthermore, a mixing unit 4 is provided on the sample container 1. The mixing unit 4 includes: a second servo motor 41, which is fixedly connected to the top of the sample container 1 and whose output end passes through the top of the sample container 1 through a sealed bearing; and a stirring rod 42, which is fixedly connected to the output end of the second servo motor 41. The output end of the second servo motor 41 drives the stirring rod 42 to stir and mix the water sample, so that the water sample inside the separatory container 22 is consistent.

[0033] In the specific implementation process, it is worth noting that the stirring rod 42 is driven to rotate by the output end of the second servo motor 41 to stir the water sample inside the sample bucket 1, so that the water flowing into the separatory bucket 22 is uniform.

[0034] Specifically, based on the above embodiment 1, the movable disk 15 is driven to rotate by the output end of the first servo motor 262, so that each dispensing tank 22 rotates in turn to the bottom of the first magnet 32. When the dispensing tank 22 is driven to rotate by the movable disk 15, through the cooperation between the first magnet 32 ​​and the second magnet 33, the first magnet 32 ​​can be attracted to the second magnet 33 at the top of the connecting tube 23 with each rotation of the dispensing tank 22. When there is an error in the rotation of the first servo motor 262, the error can be corrected by the action of the hose 31, ensuring that the water sample can completely enter the interior of the dispensing tank 22. The output end of the second servo motor 41 drives the stirring rod 42 to rotate, stirring the water sample inside the sample tank 1, so that the water flowing into the dispensing tank 22 is uniform.
