Description

Technical Field

[0001] This utility model belongs to the field of environmental water sampling technology, and in particular relates to an environmental water treatment sampling device for environmental engineering. Background Technology

[0002] In environmental engineering water treatment testing, it is necessary to sample the water body, and sampling devices are required when taking samples.

[0003] Chinese patent CN220671010U discloses an environmentally friendly water treatment sampling device for environmental engineering. The device achieves sampling by manually driving a tension line to control the opening and closing of the cover plate and uses a clamp plate for fixation, which solves the problems of material consumption and poor portability of traditional electric devices.

[0004] The aforementioned patent has the following problems: This patent has several drawbacks in its use, including: the sampling bucket and the main board are fixedly connected, lacking depth adjustment and positioning components; the sampling depth relies entirely on the manual insertion length of the handle, making it impossible to accurately control to the preset depth; and inaccurate water samples at inaccurate depths will distort the pollutant concentration detection results, affecting the formulation of water treatment solutions. Therefore, we propose an environmentally friendly water treatment sampling device for environmental engineering. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly water treatment sampling device for environmental engineering, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides an environmentally friendly water treatment sampling device for environmental engineering, including a lifting frame, an installation port on the lifting frame, an adjusting rod slidably installed in the installation port, a connector fixedly installed at the bottom end of the adjusting rod, a sampling cylinder fixedly installed on the upper side of the connector, and a sampling cover slidably installed on one side of the sampling cylinder. An adjusting rack is fixedly mounted on the surface of an adjusting rod. A rotating shaft is rotatably mounted inside the mounting opening. An adjusting gear is fixedly mounted on the surface of the rotating shaft. The adjusting gear meshes with the adjusting rack. A mounting groove is provided on one side of the lifting frame. A sliding hole is provided on the inner wall of the mounting groove. The sliding hole communicates with the mounting opening. A positioning pin is slidably mounted inside the sliding hole.

[0007] In this technical solution, the installation port on the lifting frame consists of a circular port and a rectangular port. The circular port is used for the sliding connection of the adjusting rod, and the rectangular port is used for installing the adjusting gear. A connector is fixedly installed at the bottom end of the adjusting rod. A sampling cylinder for holding water samples is fixedly installed on the upper side of the connector. A sampling cover is slidably installed on one side of the sampling cylinder for opening and closing the sampling port and adjusting the rack, which is fixedly installed on the surface of the adjusting rod. A rotating shaft is rotatably installed inside the installation port via a bearing. An adjusting gear is fixedly installed on the surface of the rotating shaft. One end of the rotating shaft extends out of the lifting frame and is equipped with a rotating handle. When the sampling depth needs to be set, the operator pulls out the positioning pin to disengage it from the adjusting gear and release the lock. Then, manually rotate the rotating shaft using the handle to drive the adjusting gear to rotate, which in turn drives the rack to move up and down, thereby driving the adjusting rod to move up and down to adjust the depth of the sampling tube. After the depth is set, re-insert the positioning pin to lock the gear and prevent it from rotating accidentally, thus firmly fixing the sampling tube at the preset depth. This allows the sampling tube to be accurately positioned at the preset depth, ensuring the representativeness of the water sample and improving the reliability of the test results.

[0008] In the above technical solution, a sealing cover is fixedly installed in the mounting groove, the positioning pin is slidably installed on the sealing cover, a limiting ring is fixedly installed on the surface of the positioning pin, the limiting ring is slidably installed in the mounting groove, and a positioning spring is fixedly installed between the limiting ring and the sealing cover.

[0009] In this technical solution, under normal conditions, the elastic force of the positioning spring pushes the limiting ring, causing the positioning pin to tend to extend outward and insert into the tooth groove of the adjusting gear, thus achieving automatic locking. When depth adjustment is required, the pin must be pulled out against the spring force; after adjustment, it is released, and the spring force will automatically push the pin back and lock it.

[0010] In the above technical solution, a take-up roller is fixedly installed on one side of the lifting frame, and an opening and closing rope is fixedly installed on the take-up roller. The opening and closing rope is fixedly installed on the upper side of the sampling cover.

[0011] In this technical solution, when the sampling cylinder reaches the predetermined depth and sampling is required, the operator on shore or boat rotates the take-up roller to tighten the opening and closing rope. The opening and closing rope pulls the sampling cover upward, opening the sampling port, and water flows into the sampling cylinder, completing the water sampling.

[0012] In the above technical solution, further, two partitions are fixedly installed on the inner wall of the sampling cylinder, two sampling ports are opened on one side of the sampling cover, the size of the sampling ports is consistent with the size of the vertical plane of the partitions, multiple limiting rods are fixedly installed on the upper side of the sampling cylinder, the sampling cover is slidably installed on the surface of the limiting rods, and a return spring is sleeved on the surface of the limiting rods, the bottom end of the return spring is fixedly connected to the upper side of the sampling cover.

[0013] In this technical solution, two partitions are fixedly installed on the inner wall of the sampling cylinder. These partitions can be increased or decreased according to actual conditions, but the number of sampling ports must remain consistent with the number of partitions. This divides the internal space of the cylinder into multiple independent chambers. Two sampling ports are opened on one side of the sampling cover. The size and position of the sampling ports match the vertical plane of the partitions; that is, when closed, the partitions block the sampling ports; when open, the sampling ports are aligned with the chambers, forming a seal. Four limiting rods are fixedly installed at the four apex positions on the upper side of the sampling cylinder. The sampling cover slides onto the surface of the limiting rods, which act as guides. A return spring is installed on the surface of each limiting rod, with a limit at the top. When the take-up roller pulls the opening and closing rope to open the sampling cover, the sampling cover slides upward along the limiting rod, compressing the return spring. At this time, the sampling ports on the sampling cover are offset from the partitions, allowing each chamber of the sampling cylinder to communicate with the external water body, while simultaneously collecting water samples from different depths independently. After the opening and closing rope is released, the compressed reset spring releases its elasticity, pushing the sampling cover to slide down and reset. The partition then re-closes the sampling port, sealing each layer of water sample in its respective chamber, thus achieving the effect of stratified sampling.

[0014] In the above technical solution, a guide block is further fixedly installed on the lower side of the connector.

[0015] In this technical solution, when the sampling device is lowered, the guide block contacts the water surface first. Its streamlined design can separate the water flow, reduce resistance, and smoothly guide the subsequent sampling tube into the water. This effectively prevents the sampling tube from entering the water roughly and generating a large amount of turbulence, avoiding stirring up the bottom sediments or destroying the original stratification of the water body, thereby collecting a more authentic and representative water sample.

[0016] In the above technical solution, a mounting base is further fixedly installed on one side of the lifting frame.

[0017] In this technical solution, the entire device can be fixed on the mounting base by weights or clamping devices.

[0018] In the above technical solution, one end of the positioning pin is spherical.

[0019] In this technical solution, the spherical end allows the pin to slide into the tooth groove along the arc surface of the tooth tip under the action of the spring force, even if there is a slight deviation between the pin and the gear tooth tip after the positioning pin is released, thus successfully completing the locking.

[0020] The beneficial effects of this utility model are: 1. The environmental water treatment sampling device in this environmental engineering project unlocks the adjusting gear by pulling the positioning pin away from it. The rotating shaft then drives the adjusting gear to rotate, which in turn moves the adjusting rack up and down, causing the adjusting rod to move up and down. The adjusting rod, through a connector, moves the sampling cylinder and guide block, thus adjusting the sampling cylinder's vertical movement. By releasing the positioning pin, a limiting ring moves under the action of a positioning spring. The limiting ring resets the positioning pin, which, guided by its spherical end, inserts into the groove of the adjusting gear, fixing the gear in place. This allows the sampling cylinder to suspend at the sampling depth, achieving the effect of adjusting the sampling depth.

[0021] 2. The environmental water treatment sampling device of this environmental engineering project retracts the opening and closing rope by rotating the take-up roller. The opening and closing rope causes the sampling cover to rise along one side of the sampling cylinder. When the sampling port is misaligned with the partition, it connects to the inside of the sampling cylinder, allowing water from different depths to enter different areas of the sampling cylinder. Then, by releasing the take-up roller, the opening and closing rope loses its tension, and the sampling cover is reset by the action of multiple reset springs, thus resetting the sampling cylinder. This achieves the effect of stratified sampling of different water layers. Attached Figure Description

[0024] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0025] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0026] Example 1: This example provides an environmental water treatment sampling device for environmental engineering, including a lifting frame 1. The lifting frame 1 has an installation port, an adjusting rod 2 is slidably installed in the installation port, a connector 3 is fixedly installed at the bottom end of the adjusting rod 2, a sampling cylinder 4 is fixedly installed on the upper side of the connector 3, and a sampling cover 16 is slidably installed on one side of the sampling cylinder 4. Adjusting rack 7 is fixedly installed on the surface of adjusting rod 2. Rotating shaft 8 is rotatably installed in the mounting opening. Adjusting gear 9 is fixedly installed on the surface of rotating shaft 8. Adjusting gear 9 meshes with adjusting rack 7. A mounting groove is opened on one side of lifting frame 1. A sliding hole is opened on the inner wall of the mounting groove. The sliding hole communicates with the mounting opening. A positioning pin 11 is slidably installed in the sliding hole.

[0027] The installation port on the lifting frame 1 consists of a circular opening and a rectangular opening. The circular opening is used for the sliding connection of the adjusting rod 2, and the rectangular opening is used for installing the adjusting gear 9. A connector 3 is fixedly installed at the bottom end of the adjusting rod 2. A sampling cylinder 4 is fixedly installed on the upper side of the connector 3 for holding water samples. A sampling cover 16 is slidably installed on one side of the sampling cylinder 4 for opening and closing the sampling port 17. The adjusting rack 7 is fixedly installed on the surface of the adjusting rod 2. A rotating shaft 8 is rotatably installed in the installation port via a bearing. An adjusting gear 9 is fixedly installed on the surface of the rotating shaft 8. One end of the rotating shaft 8 extends out of the lifting frame 1 and is equipped with a rotating handle. When it is necessary to set the sampling depth, the operator pulls out the positioning pin 11 to disengage it from the adjusting gear 9 and release the lock. Then, manually rotate the rotating shaft 8 using the rotating handle, which will drive the adjusting gear 9 to rotate. This will drive the rack to move up and down, thereby driving the adjusting rod 2 to move up and down, thus adjusting the depth of the sampling tube 4. After the depth is set, re-insert the positioning pin 11 to form a position and lock the gear to prevent it from rotating accidentally. This will firmly fix the sampling tube 4 at the preset depth, accurately positioning the sampling tube 4 at the preset depth, ensuring the representativeness of the water sample, and improving the reliability of the test results.

[0028] Example 2: This example provides an environmental water treatment sampling device for environmental engineering. In addition to the technical solutions of the above examples, it also has the following technical features: a sealing cover 14 is fixedly installed in the installation groove, a positioning pin 11 is slidably installed on the sealing cover 14, a limiting ring 12 is fixedly installed on the surface of the positioning pin 11, the limiting ring 12 is slidably installed in the installation groove, and a positioning spring 13 is fixedly installed between the limiting ring 12 and the sealing cover 14.

[0029] In its natural state, the spring force of the positioning spring 13 pushes the limiting ring 12, causing the positioning pin 11 to tend to extend outward and insert into the tooth groove of the adjusting gear 9, thus achieving automatic locking. When depth adjustment is required, the pin must be pulled out against the spring force; after adjustment, it is released, and the spring force will automatically push the pin back and lock it.

[0030] Example 3: This example provides an environmental water treatment sampling device for environmental engineering. In addition to the technical solutions of the above examples, it also has the following technical features: a take-up roller 5 is fixedly installed on one side of the lifting frame 1, and an opening and closing rope 6 is fixedly installed on the take-up roller 5. The opening and closing rope 6 is fixedly installed on the upper side of the sampling cover 16.

[0031] When the sampling cylinder 4 reaches the predetermined depth and sampling is required, the operator rotates the take-up roller 5 on the shore or boat to tighten the opening and closing rope 6. The opening and closing rope 6 pulls the sampling cover 16 upward to slide, opening the sampling port 17, and water flows into the sampling cylinder 4, completing the water sampling.

[0032] Example 4: This example provides an environmental water treatment sampling device for environmental engineering. In addition to the technical solutions of the above examples, it also has the following technical features: two partitions 15 are fixedly installed on the inner wall of the sampling cylinder 4, and two sampling ports 17 are opened on one side of the sampling cover 16. The size of the sampling ports 17 is consistent with the size of the vertical plane of the partitions 15. Multiple limiting rods 18 are fixedly installed on the upper side of the sampling cylinder 4. The sampling cover 16 is slidably installed on the surface of the limiting rods 18. A return spring 19 is sleeved on the surface of the limiting rods 18, and the bottom end of the return spring 19 is fixedly connected to the upper side of the sampling cover 16.

[0033] Two partitions 15 are fixedly installed on the inner wall of the sampling cylinder 4. These can be increased or decreased as needed, but the number of sampling ports 17 must match the number of partitions 15, dividing the cylinder space into multiple independent chambers. Two sampling ports 17 are opened on one side of the sampling cover 16. The size and position of the sampling ports 17 match the vertical plane of the partitions 15; that is, when closed, the partitions 15 block the sampling ports 17; when open, the sampling ports 17 are aligned with the chambers, forming a seal. Four limiting rods 18 are fixedly installed at the four apex positions on the upper side of the sampling cylinder 4. The sampling cover 16 slides on the surface of the limiting rods 18, which act as guides. A return spring 19 is fitted on the surface of each limiting rod 18, with a limit at the top. When the take-up roller 5 pulls the opening and closing rope 6 to open the sampling cover 16, the sampling cover 16 slides upward along the limiting rod 18, compressing the return spring 19. At this time, the sampling port 17 on the sampling cover 16 is offset from the partition 15, allowing each chamber of the sampling cylinder 4 to communicate with the external water body, while simultaneously collecting water samples from different depths independently. After the opening and closing rope 6 is released, the compressed return spring 19 releases its elasticity, pushing the sampling cover 16 to slide down and reset, and the partition 15 re-closes the sampling port 17, sealing each layer of water sample in its respective chamber, achieving the effect of stratified sampling.

[0034] Example 5: This example provides an environmental water treatment sampling device for environmental engineering. In addition to the technical solutions of the above examples, it also has the following technical features: a guide block 20 is fixedly installed on the lower side of the connector 3.

[0035] When the sampling device is lowered, the guide block 20 contacts the water surface first. Its streamlined design can separate the water flow, reduce resistance and smoothly guide the subsequent sampling tube 4 into the water. This effectively prevents the sampling tube 4 from entering the water roughly and generating a large amount of turbulence, avoiding stirring up the bottom sediments or destroying the original stratification of the water body, thereby collecting a more authentic and representative water sample.

[0036] Example 6: This example provides an environmental water treatment sampling device for environmental engineering. In addition to the technical solutions of the above examples, it also has the following technical features: a mounting base 10 is fixedly installed on one side of the lifting frame 1.

[0037] The entire device can be secured on the mounting base 10 using weights or clamping devices.

[0038] Example 7: This example provides an environmentally friendly water treatment sampling device for environmental engineering. In addition to the technical solutions of the above examples, it also has the following technical features: one end of the positioning pin 11 is spherical.

[0039] The spherical end allows the pin to slide into the tooth groove along the arc surface of the tooth tip under the action of the spring force, even if there is a slight deviation between the pin and the gear tooth tip after the positioning pin 11 is released, thus successfully completing the locking.

[0040] Working principle: When using the device, first place it in the water source area where sampling is required, and fix it in the area with other weights using the mounting base 10, so that the sampling tube 4 faces the water source. Then, pull the positioning pin 11 with one hand to move the positioning pin 11 away from the adjusting gear 9 and unlock the adjusting gear 9. With the other hand, turn the rotating handle connected to the rotating shaft 8 to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the adjusting gear 9 to rotate. The adjusting gear 9 drives the adjusting rack 7 to move up and down, which in turn drives the adjusting rod 2 to move up and down. The adjusting rod 2 drives the sampling tube 4 and the guide block 20 to move through the connecting piece 3, moving the sampling tube 4 and the guide block 20 downward synchronously. The guide block 20 breaks the water to reduce water disturbance and moves the sampling tube 4 to the predetermined sampling depth. Loosen the positioning pin 11, and under the action of the positioning spring 13, drive the limiting ring 12 to move. The limiting ring 12 drives the positioning pin 11 to reset, and under the guidance of the ball end, inserts into the tooth groove of the adjusting gear 9 to fix and limit the adjusting gear 9, so that the sampling cylinder 4 is suspended at the sampling depth. Then, manually rotate the take-up roller 5 to drive the opening and closing rope 6 to retract. The opening and closing rope 6 drives the sampling cover 16 to rise along one side of the sampling cylinder 4. When the sampling port 17 is misaligned with the partition 15, it connects to the inside of the sampling cylinder 4, allowing water of different depths to enter different areas of the sampling cylinder 4, thus completing the stratified extraction of water. After sampling is completed, the take-up roller 5 is released to release the tension of the opening and closing rope 6. Under the action of multiple reset springs 19, the sampling cover 16 is reset, and the sampling cylinder 4 is reset. Finally, the above operation is repeated to retract the sampling cylinder 4, thus completing the water sampling.
