Abstract
Description
Technical Field
[0001] This utility model relates to the field of water sample collection technology, and in particular to a lightweight water sample collection device. Background Technology
[0002] With the acceleration of global industrialization and the continuous growth of population, the importance of environmental protection and water resource monitoring has become increasingly prominent. As the source of life and the basic resource for human social development, water quality is directly related to human health, ecosystem balance, and sustainable economic and social development. Therefore, scientific and accurate monitoring and assessment of water resources has become a key link in ensuring water environment safety. Water sample collection, as a basic step in water quality testing, environmental monitoring, and scientific research, is of paramount importance.
[0003] Traditional water sample collection devices are usually operated manually, using a single sampling tube or pump for sampling. However, these devices have many limitations in practical use. First, most traditional devices can only perform a single sampling. After completing one sampling, the sample needs to be removed and the device needs to be prepared again before the next sampling can be performed. This process is not only cumbersome and time-consuming, but also prone to sample contamination or damage due to frequent manual operation, which seriously affects sampling efficiency and sample quality. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a lightweight water sample collection device.
[0005] This utility model is achieved using the following technical solution: a lightweight water sample collection device, including a collection box, an installation plate fixedly connected to the inner wall of the collection box, a sampling pump fixedly installed on the upper surface of the installation plate by bolts, a suction tube fixedly connected to the input end of the sampling pump, a telescopic corrugated pipe fixedly connected to the surface of the suction tube, a movable plate fixedly connected to the surface of the telescopic corrugated pipe, a limit groove opened on the surface of the collection box, a lead screw threadedly connected to the surface of the movable plate, a knob fixedly connected to the top end of the lead screw, a delivery pipe fixedly connected to the output end of the sampling pump, and a collection mechanism provided inside the collection box;
[0006] The collection mechanism includes a drive motor, the output end of which is fixedly connected to a worm gear, the surface of which is meshed with a worm wheel, the inside of which is fixedly connected to a rotating rod, the bottom end of which is rotatably connected to a base, and the top end of which is fixedly connected to a positioning plate, the upper surface of which is provided with several sample tubes.
[0007] The above technical solution solves the problem that traditional sampling devices can only take a single sample at a time, and that a second sample can only be taken after the sample has been removed and collected. This effectively improves the efficiency of water sample collection. The design of the collection mechanism enables automatic switching of sample tubes, reduces manual operation, and improves the automation and accuracy of the sampling process.
[0008] As a further improvement to the above solution, the bottom end of the lead screw is rotatably connected to a bearing seat, which is fixedly connected to the surface of the data collection box.
[0009] As a further improvement to the above solution, the movable plate is slidably connected to the inside of the limiting groove.
[0010] The above technical solutions ensure the smoothness and accuracy of the movement of the movable plate, prevent the movable plate from shifting or jamming during movement, and improve the stability and reliability of the sampling process.
[0011] As a further improvement to the above scheme, the delivery tube is located above the sample tube.
[0012] As a further improvement to the above solution, the drive motor is fixedly connected to the inner wall of the acquisition box, and the worm gear is rotatably connected to the inner wall of the acquisition box.
[0013] As a further improvement to the above solution, the surface of the collection box is hinged with a sealing cover.
[0014] Using the above technical solution, personnel can open the sealed cover and take out the collected sample tube, and then extract the water sample inside the sample tube.
[0015] As a further improvement to the above solution, self-locking casters are fixedly connected to the four corners of the lower surface of the collection box.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention uses a knob to rotate a lead screw, which in turn causes a movable plate to descend smoothly along a limiting groove. This allows the telescopic bellows to flexibly adjust to a new sampling position. The flexible material of the telescopic bellows and the guiding effect of the limiting groove ensure flexible adjustment of the sampling position. Simultaneously, the collection mechanism uses a drive motor to rotate a worm gear, worm wheel, and rotating rod, causing the sample tube on the positioning plate to automatically switch positions. The new sample tube can quickly and accurately rotate to the bottom of the delivery tube, thus achieving secondary sample collection. This avoids the cumbersome process of removing and re-preparing samples for secondary sampling, which is required in traditional sampling devices. This greatly improves sampling efficiency, reduces manual operation time and labor intensity, and ensures the continuity of sampling work and the accuracy of samples. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] Example:
[0026] Please combine Figure 1-4 This embodiment of a lightweight water sample collection device includes a collection box 1, an installation plate 2 fixedly connected to the inner wall of the collection box 1, a sampling pump 3 fixedly installed on the upper surface of the installation plate 2 by bolts, a suction tube 4 fixedly connected to the input end of the sampling pump 3, a telescopic corrugated tube 5 fixedly connected to the surface of the suction tube 4, a movable plate 6 fixedly connected to the surface of the telescopic corrugated tube 5, a limit groove 7 opened on the surface of the collection box 1, a lead screw 8 threadedly connected to the surface of the movable plate 6, a knob 9 fixedly connected to the top end of the lead screw 8, a delivery tube 10 fixedly connected to the output end of the sampling pump 3, and a collection mechanism 11 provided inside the collection box 1.
[0027] The collection mechanism 11 includes a drive motor 111. A worm gear 112 is fixedly connected to the output end of the drive motor 111. A worm wheel 113 is meshed with the surface of the worm gear 112. A rotating rod 114 is fixedly connected inside the worm wheel 113. A base 115 is rotatably connected to the bottom end of the rotating rod 114. A positioning plate 116 is fixedly connected to the top end of the rotating rod 114. Several sample tubes 117 are arranged on the upper surface of the positioning plate 116. By rotating the knob 9, the lead screw 8 is rotated, causing the movable plate 6 to descend along the limiting groove 7. The descent of the movable plate 6 causes the telescopic bellows 5 to descend. The flexible material of the telescopic bellows 5 allows it to be stretched, thus moving to the appropriate position. Once the desired position is reached, the sampling pump 3 is activated. The sampling pump 3 extracts water samples through the suction tube 4 and the telescopic corrugated tube 5, and transports the samples to the collection mechanism 11 through the delivery tube 10. When a second sampling is required, the telescopic corrugated tube 5 continues to descend. After reaching the desired position, the collection mechanism 11 is activated, and the drive motor 111 drives the worm gear 112 to rotate. The worm gear 112 drives the worm wheel 113 to rotate, which in turn drives the rotating rod 114 to rotate. The rotation of the rotating rod 114 drives the positioning disk 116 above to rotate, causing the sample tube 117 above the positioning disk 116 to change position. The new sample tube 117 rotates back to below the delivery tube 10 for secondary sample collection.
[0028] The bottom end of the lead screw 8 is rotatably connected to a bearing seat 12, which is fixedly connected to the surface of the data acquisition box 1. The bearing seat 12 provides stable rotational support for the bottom end of the lead screw 8, ensuring that the lead screw 8 remains stable during rotation and preventing the movement of the movable plate 6 from being unstable due to the shaking or instability of the lead screw 8.
[0029] The movable plate 6 is slidably connected inside the limiting groove 7. The limiting groove 7 restricts and guides the movement direction of the movable plate 6, ensuring that the movable plate 6 can move up and down smoothly and accurately along the predetermined trajectory, thereby driving the telescopic corrugated pipe 5 to achieve stable telescopic movement.
[0030] The delivery tube 10 is located above the sample tube 117.
[0031] The drive motor 111 is fixedly connected to the inner wall of the acquisition box 1, and the worm gear 112 is rotatably connected to the inner wall of the acquisition box 1.
[0032] The surface of the collection box 1 is hinged with a sealing cover 13. When personnel open the sealing cover 13, they can take out the collected sample tube 117 and then take out the water sample inside the sample tube 117.
[0033] Self-locking casters 14 are fixedly connected to the four corners of the lower surface of the data collection box 1.
[0034] The implementation principle of a lightweight water sample collection device in this embodiment is as follows: The operator first moves the device to the target sampling location. Since self-locking casters 14 are fixedly connected to the four corners of the lower surface of the collection box, moving the device becomes extremely convenient. The operator can easily push it to the desired location. The operator then turns the knob 9, which drives the lead screw 8 to rotate. Because the bottom end of the lead screw 8 is fixedly connected to the surface of the collection box 1 via a bearing 12, the bearing 12 provides stable rotational support for the lead screw 8, ensuring that the lead screw 8 does not wobble during rotation. The rotation of the lead screw 8 causes its screw to... The movable plate 6, connected by a groove, descends smoothly along the limiting groove 7 on the surface of the sampling box. The limiting groove 7 restricts and guides the movement direction of the movable plate 6, ensuring that the movable plate 6 can move up and down accurately along a predetermined trajectory. The descent of the movable plate 6 causes the telescopic bellows 5 to descend. The flexible material of the telescopic bellows 5 allows it to be stretched, thus enabling it to be flexibly adjusted to a suitable sampling position. Once the telescopic bellows 5 has moved to the appropriate position, the operator starts the sampling pump 3. The sampling pump 3 extracts samples from the water through the suction pipe 4 and the telescopic bellows 5, and transports the samples to the sampling box through the delivery pipe 10. The collection mechanism 11 inside the collection box has a delivery pipe 10 located above the sample tube 117, ensuring that the sample can flow smoothly into the sample tube 117 for storage. If secondary sampling is required, the operator continues to turn the knob 9 to lower the telescopic bellows 5 to a new sampling position. Once the appropriate position is reached, the operator starts the collection mechanism 11. The drive motor 111 in the collection mechanism 11 is fixedly connected to the inner wall of the collection box 1, providing stable power to the worm gear 112. The drive motor 111 drives the worm gear 112 to rotate, and the worm gear 112 meshes with the worm wheel 113, thereby driving the worm... The worm gear 113 rotates, and a rotating rod 114 is fixedly connected inside the worm gear 113. The rotation of the rotating rod 114 drives the positioning disk 116 above to rotate. Several sample tubes 117 are set on the upper surface of the positioning disk 116. As the positioning disk 116 rotates, the position of the sample tubes 117 changes, and the new sample tubes 117 rotate back to the bottom of the delivery pipe 10, so that secondary sample collection can be performed. After the sampling is completed, the operator opens the sealing cover 13 again, takes out the collected sample tubes 117, and then takes out the water sample inside the sample tubes 117 for subsequent analysis and testing.
[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
