Description

Technical Field

[0001] The present application relates to the technical field of hydrological resource surveying, and in particular to a portable hydrological and water resource surveying device. Background Art

[0002] Hydrological and water resources survey is the work of conducting hydrological tests and hydrological surveys for the purpose of systematically collecting hydrological data. Water is a good solvent. Various factors in the natural environment have a significant impact on natural water. Sampling water bodies is an important part of hydrological surveys. Conventional vessels such as buckets can be used to collect surface water samples, while special sampling equipment is required to collect deep water samples.

[0003] In the prior art, there is a portable hydrological and water resources survey device with a publication number of CN219977882U, which can conveniently take samples at different depths to prevent water flows at different depths from contaminating the sampling liquid;

[0004] The device controls the circular plate to move relative to the cylinder until the second opening is aligned with the first opening to realize sampling. However, this sampling method can only take out samples of a single water layer at a time. When sampling multiple water layers, the cylinder needs to be retracted and released multiple times, which makes the work efficiency low. At the same time, foreign matter such as garbage floating in the water body is easy to cover the circular plate, causing the blockage of the first opening, reducing the success rate of sampling. In addition, the water sample in the cylinder is not easy to take out, and it is not convenient to use.

[0005] Therefore, the present application provides a convenient hydrological and water resources survey device to meet the needs. Utility Model Content

In addition, by setting a filter and a cleaning structure, the situation of foreign matter covering the sampling port is reduced, so that the sampling work can be carried out smoothly. When taking out samples, the samples in the sampling tubes can be taken out one by one, which is not easy to interfere with each other and is more convenient.

DETAILED DESCRIPTION

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 A portable hydrological and water resources surveying device is shown, and the embodiment of the present application provides, comprising a housing 1 and a rotatable dispensing tray 2 inside thereof, a sampling tube 3 arranged on the dispensing tray 2, a top cover 4 covering the sampling tube 3, a sampling port being provided inside the top cover 4, a servo motor 101 for driving the dispensing tray 2 to rotate being provided at the inner bottom end of the housing 1, a connecting rod 201 being fixedly connected at the top center of the dispensing tray 2, one end of the connecting rod 201 passing through the top cover 4 being connected to a scraper 202, a limiting step 301 being provided on the inner wall surface of the sampling tube 3, a spring 302 being provided on the top of the limiting step 301, and a clamping block 303 being clamped on the top of the spring 302;

[0035] The device is placed in the water body through an external rope, and the length of the rope is controlled so that the device can stay at the depth of a predetermined water layer. The servo motor 101 drives the dispensing plate 2 to rotate, so that the single sampling tube 3 is aligned with the sampling port on the top cover 4, and the water sample can enter the sampling tube 3 through the top cover 4;

[0036] After a single sampling tube 3 is used up, the servo motor 101 drives the dispensing plate 2 to continue rotating, and the used sampling tube 3 is separated from the sampling port, and the top opening of the sampling tube 3 is closed by the top cover 4, so that the collected water sample can be safely stored and not easily contaminated by the outside, and then the servo motor 101 is started again to move the entire device to the next water layer, and the sampling operation is repeated to complete the collection of samples of multiple water layers at different depths;

[0037] When the dispensing plate 2 rotates, the connecting rod 201 is driven to rotate, and the connecting rod 201 is used to drive the scraper 202 to reciprocate, and the scraper 202 continuously cleans the top cover 4. Foreign matter attached to the surface of the top cover 4 can be scraped by the scraper 202 to a position away from the sampling port, thereby ensuring the unobstructed flow of the sampling port and the success rate of sampling;

[0038] After the sampling tube 3 on the dispensing plate 2 is used up, the entire device is taken out from the water body, and the dispensing plate 2 is driven to rotate by the servo motor 101, so that the sampling tube 3 is aligned with the sampling port in turn, the sampling tube 3 is tilted, and the clamping block 303 is pressed to overcome the resistance of the spring 302 to shrink it, and the clamping block 303 is received into the sampling tube 3, and the sample inside can be poured out from the sampling port in turn. Only a single sample is taken out at a time, and the sample removal process is efficient, and cross contamination between samples is avoided, which is more convenient.

[0039] In this embodiment, Figure 2-Figure 6 As shown; the housing 1 is a cylindrical structure with a pointed tip at the bottom, the housing 1 and the top cover 4 are connected as a whole through threads, and the outer wall of the housing 1 is provided with a lifting ear 102;

[0040] The lifting ear 102 is used to connect the external rope. A streamlined tip is provided at the bottom of the outer shell 1. When the outer shell 1 is placed in the water body, it sinks stably and is not easy to rotate. It can quickly reach the designated water layer for sampling. The outer shell 1 and the top cover 4 are flexibly disassembled and assembled through threads, which facilitates the replacement and maintenance of the sampling tube 3 and is more convenient to use.

[0041] The dispensing tray 2 is a cylindrical structure, the outer circumference of the dispensing tray 2 is in contact with the inner wall of the housing 1, and a sealing ring 203 is provided on the outer circumference of the dispensing tray 2;

[0042] A snap-in groove is provided on the top of the dispensing tray 2, and the snap-in groove is arranged in a circular array with the center of the upper end surface of the dispensing tray 2 as the center of the circle, and the sampling tube 3 is snap-fitted into the snap-in groove on the top of the dispensing tray 2;

[0043] The dispensing tray 2 is guided by the inner wall of the outer shell 1 and can rotate stably. A sealing ring 203 is arranged between the dispensing tray 2 and the outer shell 1. The sealing ring 203 is used to achieve sealing to reduce the invasion of water on the servo motor 101 and improve the safety of the overall use of the device. The clamping groove arranged on the dispensing tray 2 can stably limit the sampling tube 3, ensuring the accuracy of the position of the sampling tube 3 relative to the sampling port, and is convenient for disassembly and assembly.

[0044] The bottom side wall of the clamping groove of the dispensing plate 2 is fixedly connected with a suction cup 204, and the sampling tube 3 is a flat-bottomed glass tube;

[0045] The suction cup 204 further fixes the sampling tube 3 on the dispensing tray 2. The suction force of the suction cup 204 can achieve a good anti-falling effect and keep the sampling tube 3 in a vertical state relative to the dispensing tray 2, making loading and unloading convenient.

[0046] The bottom side wall of the top cover 4 is provided with an annular limiting groove, a sealing gasket 401 is fitted in the bottom limiting groove of the top cover 4, and a through hole corresponding to the sampling port is provided on one side of the sealing gasket 401;

[0047] The end of the sampling tube 3 is embedded in the limiting groove of the top cover 4, and the opening of the sampling tube 3 is attached to the surface of the sealing gasket 401;

[0048] The top cover 4 fits well with the sampling tube 3, further limiting the vertical movement space of the sampling tube 3. The sampling tube 3 fits well on the sealing gasket 401, playing a good sealing role to avoid contamination caused by sample leakage. At the same time, the sampling tube 3 is limited by the limiting groove at the bottom of the top cover 4, and the horizontal displacement space is further reduced. The sampling tube 3 is more stable, ensuring a good fit between the sampling tube 3 and the sealing gasket 401.

[0049] The top sampling port of the top cover 4 is connected with a screw cap 402, and a filter screen 403 is fixedly connected in the top opening of the screw cap 402;

[0050] By providing a conveniently detachable screw cap 402 at the sampling port, and providing a filter screen 403 on the screw cap 402, the screw cap 402 prevents the sampling tube 3 from being separated from the device as a whole from the top cover 4, and at the same time enhances the separation effect of impurities and reduces interference from foreign matter.

[0051] A guide hole is provided at the center of the top surface of the sampling tube 3, and water inlets are provided around the top of the sampling tube 3;

[0052] A guide protrusion 304 is provided at the center of the top of the clamping block 303. The guide protrusion 304 is clamped in the guide hole of the sampling tube 3. The top of the guide protrusion 304 is in a hemispherical shape.

[0053] A through hole is formed on the top of the block 303, and the through hole and the water inlet on the top of the sampling tube 3 are staggered in vertical arrangement;

[0054] When the opening of the sampling tube 3 fits on the sealing gasket 401, the top opening of the sampling tube 3 is closed, and the block 303 is pressed by the spring 302, so that the block 303 can fit on the bottom surface of the sealing gasket 401, achieving a good sealing effect. When the opening of the sampling tube 3 faces the screw cap 4, the block 303 is limited by the screw cap 402 and cannot be fully extended, so that a liquid flow channel is reserved between the block 304 and the top of the sampling tube 3, and the water sample can flow into the sampling tube 3.

[0055] After the top cover 4 is disassembled and separated from the housing 1 and the screw cap 402 is separated from the sampling tube 3, the clamp block 303 is pressed against the opening of the sampling tube 3 by the spring 302, and the liquid flow channel between the clamp block 303 and the sampling tube 3 is blocked by the tube wall, thereby preventing the sample from flowing out of the sampling tube 3;

[0056] The guide protrusion 304 has an outer convex arc surface, and can automatically retract into the sampling tube 3 when being squeezed by the sealing gasket 401 .

[0057] The lower surface of the screw cap 402 abuts against the top surface of the sealing gasket 401;

[0058] The screw cap 402 has a limiting effect on the sealing gasket 401 and the sampling tube 3;

[0059] A through hole is formed on the bottom surface of the rotary cover 402;

[0060] It ensures that the water sample enters the sampling tube 3 normally.
