Description

Technical Field

[0001] This invention belongs to the field of hydrological information acquisition technology, specifically a hydrological survey sample collector. Background Technology

[0002] Hydrological information is a hydrological term referring to the collective results of measured hydrological data and their analysis. It serves as a crucial basis for watershed management, engineering planning and design, flood control and drought relief, and the formulation of socio-economic development plans.

[0003] Currently, during hydrological surveys, it is usually necessary to sample water sources at different depths within a body of water. In existing technologies, water sampling is mostly carried out by submerging a container to hold the water source into the water body. Once the container reaches the predetermined depth, the valve of the container's inlet pipe is opened, and the water source at the predetermined depth is automatically filled into the container through the inlet pipe, thus collecting the water source sample. This sampling method is relatively traditional. During the process of the container sinking into the water body, due to its own volume and the presence of air inside the container, the container will encounter a large buoyancy, resulting in a relatively slow sinking speed and thus a relatively low water sample collection efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a hydrological survey sample collector.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A hydrological survey sample collector includes a connecting tube, a flexible sampling component, a counterweight, and a limiting component.

[0007] One end of the connecting pipe is connected to the air supply assembly, and the other end is connected to the counterweight.

[0008] The flexible acquisition component is installed on the connecting pipe.

[0009] The limiting component is disposed inside the flexible acquisition component and is used to confine the flexible acquisition component to a compressed state.

[0010] When the air supply component delivers air into the connecting pipe, the connecting pipe expands and deforms to move the limiting component, thereby releasing the restriction on the compressed state of the flexible collection component. The collection component then expands to draw water into its interior.

[0011] As a further improvement of the present invention: the flexible acquisition component includes a first plate, a flexible layer, and a second plate.

[0012] The second plate is mounted on one side of the connecting pipe, and the first plate is disposed on the side of the second plate away from the connecting pipe and connected to the second plate through the flexible layer.

[0013] The limiting assembly includes a first pull rod and a second pull rod.

[0014] One end of the first pull rod is connected to the second plate, and one end of the second pull rod is connected to the first plate. Both the end of the first pull rod away from the second plate and the end of the second pull rod away from the first plate have a hook-shaped structure.

[0015] As a further improvement of the present invention: a sleeve is fixedly provided on one side of the second plate, and a water inlet is provided on the side wall of the second plate; the connecting pipe passes through the sleeve and is movably engaged with the sleeve.

[0016] One end of the first pull rod extends into the inside of the sleeve, and the side wall of the first pull rod is rotatably connected to the second plate body via a pin.

[0017] The sleeve sidewall is connected to the first pull rod via a third elastic element, which provides elastic tension to the first pull rod.

[0018] The first plate and the second plate are also connected by a first elastic element, which provides elastic support for the first plate.

[0019] As a further improvement of the present invention, the connecting pipe has an elliptical structure.

[0020] As a further improvement to the present invention, it also includes a sealing component.

[0021] During the process of the flexible acquisition component entering the water body, the sealing component is used to seal the water inlet.

[0022] As a further improvement of the present invention: the sealing assembly includes a second elastic element, a first sealing plate, a guide rod, and a second sealing plate.

[0023] One end of the guide rod is fixedly connected to one side of the second plate, and the other end passes through the first sealing plate and is movably fitted with the first sealing plate. The first sealing plate is disposed between the first plate and the second plate and is movably sleeved on the outside of the guide rod.

[0024] One end of the first elastic element is connected to the second plate, and the other end is connected to the first sealing plate, for providing elastic support to the first sealing plate.

[0025] The second sealing plate is fixedly installed at the end of the guide rod away from the second plate body.

[0026] As a further improvement of the present invention: a drain pipe is provided on one side of the first plate, and a sealing plug is provided at the end of the drain pipe.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] In this embodiment of the invention, during hydrological surveys and water source collection, the connecting pipe can be manipulated so that a counterweight pulls the connecting pipe into the water body. At this time, the flexible sampling component enters the water body along with the connecting pipe. During this process, a limiting component restricts the flexible sampling component to a compressed state, thereby reducing its volume and the resistance when it enters the water body. When the flexible sampling component reaches a predetermined depth, an air supply component supplies air into the connecting pipe to cause it to expand and deform, which in turn moves the limiting component, releasing the restriction on the compressed state of the flexible sampling component. At this point, the flexible sampling component expands and deforms, drawing water into its interior, thus achieving water sample collection. Compared to existing technologies, this method reduces the volume of the flexible sampling component during its entry into the water body, thereby reducing resistance and ensuring that the flexible sampling component can quickly reach the predetermined depth. When the flexible sampling component reaches the predetermined depth, automatic water sample collection is achieved, resulting in good water sample collection effect and high collection efficiency.

Detailed Implementation

[0035] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0036] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0037] Please see Figure 1 , Figure 4 and Figure 5 This embodiment provides a hydrological survey sample collector, including a connecting pipe 10, a flexible collection component 20, a counterweight 30, and a limiting component 50. One end of the connecting pipe 10 is connected to an air supply component (not shown in the figure), and the other end is connected to the counterweight 30. The flexible collection component 20 is installed on the connecting pipe 10. The limiting component 50 is disposed inside the flexible collection component 20 to limit the flexible collection component 20 to a compressed state. When the air supply component supplies air into the connecting pipe 10, the connecting pipe 10 expands and deforms to drive the limiting component 50 to move, thereby releasing the limitation of the flexible collection component 20 to a compressed state. The collection component 20 expands to draw water into the collection component 20.

[0038] During hydrological surveys and water source collection, the connecting pipe 10 can be manipulated so that the counterweight 30 pulls the connecting pipe 10 into the water body. At this time, the flexible collection component 20 enters the water body along with the connecting pipe 10. During this process, the limiting component 50 restricts the flexible collection component 20 to a compressed state, thereby reducing the volume of the flexible collection component 20 and reducing the resistance when the flexible collection component 20 enters the water body. When the flexible collection component 20 reaches a predetermined depth, air is supplied to the connecting pipe 10 through the air supply component to drive the connecting pipe 10 to expand and deform, thereby driving the limiting component 50 to move and release the restriction on the compressed state of the flexible collection component 20. At this time, the flexible collection component 20 expands and deforms to draw the water source into the flexible collection component 20, thereby realizing the collection of water samples.

[0039] Please see Figure 1 and Figure 5 In one embodiment, the flexible acquisition component 20 includes a first plate 201, a flexible layer 202, and a second plate 203. The second plate 203 is installed on one side of the connecting pipe 10. The first plate 201 is disposed on the side of the second plate 203 away from the connecting pipe 10 and is connected to the second plate 203 through the flexible layer 202. The limiting component 50 includes a first pull rod 501 and a second pull rod 503. One end of the first pull rod 501 is connected to the second plate 203, and one end of the second pull rod 503 is connected to the first plate 201. The ends of the first pull rod 501 and the second pull rod 503 away from the second plate 203 are both hook-shaped.

[0040] When the connecting pipe 10 drives the flexible acquisition component 20 into the water, the first pull rod 501 and the second pull rod 503 hook each other, causing the first plate 201 to be close to the second plate 203. The flexible layer 202 folds and contracts, so that the flexible acquisition component 20, composed of the first plate 201, the flexible layer 202 and the second plate 203, is in a compressed state, thereby reducing the volume and resistance, and ensuring that the flexible acquisition component 20 can smoothly enter the water.

[0041] Please see Figure 4 and Figure 5 In one embodiment, a sleeve 204 is fixedly provided on one side of the second plate 203, and a water inlet 206 is provided on the side wall of the second plate 203. The connecting pipe 10 passes through the sleeve 204 and is movably engaged with the sleeve 204. One end of the first pull rod 501 extends into the inside of the sleeve 204. The side wall of the first pull rod 501 is rotatably connected to the second plate 203 through a pin. The side wall of the sleeve 204 is connected to the first pull rod 501 through a third elastic element 502. The third elastic element 502 is used to provide elastic tension to the first pull rod 501. The first plate 201 and the second plate 203 are also connected through a first elastic element 207. The first elastic element 207 is used to provide elastic support to the first plate 201.

[0042] When the flexible collection component 20 reaches a predetermined depth inside the water body, air is supplied to the connecting pipe 10 through the air supply component. The air can drive the part of the connecting pipe 10 located inside the sleeve 204 to expand outward, thereby squeezing one end of the first pull rod 501. When one end of the first pull rod 501 is compressed, it can overcome the elastic tension of the third elastic element 502 and rotate, causing the other end of the first pull rod 501, which has a hook-like structure, to rotate adaptively, thereby releasing the second pull rod 503. At this time, under the support of the first elastic element 207, the first plate 201 is driven away from the second plate 203, and the flexible layer 202 is adaptively unfolded. During the movement of the first plate 201, external water source can be sucked into the space between the first plate 201 and the second plate 203 through the water inlet 206, thus realizing the collection of water source.

[0043] Please see Figure 2 and Figure 3 In one embodiment, the connecting pipe 10 has an elliptical structure so that the inner side of the connecting pipe 10 and the sleeve 204 has space for the connecting pipe 10 to expand and deform, so that when the connecting pipe 10 expands, it can smoothly squeeze one end of the first pull rod 501, thereby driving the other end of the first pull rod 501, which has a hook-like structure, to rotate smoothly.

[0044] Please see Figure 4 In one embodiment, the hydrological survey sample collector further includes a sealing component 40. During the process of the flexible collection component 20 entering the water body, the sealing component 40 is used to seal the water inlet 206 to prevent external water from entering between the first plate 201 and the second plate 203 from the water inlet 206, thereby ensuring the accuracy of subsequent water source collection.

[0045] Please see Figure 2 , Figure 3 and Figure 4 In one embodiment, the sealing assembly 40 includes a second elastic element 401, a first sealing plate 402, a guide rod 403, and a second sealing plate 404. One end of the guide rod 403 is fixedly connected to one side of the second plate 203, and the other end passes through the first sealing plate 201 and is movably engaged with the first sealing plate 201. The first sealing plate 402 is disposed between the first plate 201 and the second plate 203 and is movably sleeved outside the guide rod 403. One end of the first elastic element 401 is connected to the second plate 203, and the other end is connected to the first sealing plate 402, for providing elastic support for the first sealing plate 402. The second sealing plate 404 is fixedly installed at the end of the guide rod 404 away from the second plate 203.

[0046] By pressing the first plate 201 towards the second plate 203, the second pull rod 503 hooks with the first pull rod 501, thus confining the first plate 201 to one side of the second plate 202. At this time, the first sealing plate 402, supported by the second elastic member 401, adheres to the inner wall of the first plate 201 to block the water inlet 206, preventing water from entering between the first plate 201 and the second plate 203. When the first plate 201 and the second plate 203 enter the water body to a predetermined depth along with the connecting pipe 10, the air supply component supplies air into the connecting pipe 10. The air drives the connecting pipe 102 to expand inside the sleeve 204 and squeeze one end of the first pull rod 501, causing the first pull rod 501 to... Overcoming the elastic tension of the third elastic element 502, the rotation releases the hook from the second pull rod 503. At this time, under the support of the first elastic element 207, the first plate 201 moves away from the second plate 201, and the flexible layer 202 unfolds accordingly. The first sealing plate 402 releases the blockage of the inlet 206, and external water is drawn through the inlet 206 to the space between the first plate 201 and the second plate 203. The inlet 206 is then blocked again when the second sealing plate 404 is attached to the outside of the first plate 201, thus sealing the water source between the first plate 201 and the second plate 203. By manipulating the connecting pipe 10, the flexible collection component 20 is removed from the water body, completing the water sample collection.

[0047] Please see Figure 1 and Figure 3 In one embodiment, a drain pipe 205 is provided on one side of the first plate 201, and a sealing plug is provided at the end of the drain pipe 205.

[0048] After the flexible collection component 20 is removed from the water body, the sealing plug can be opened to discharge the water sample between the first plate 201 and the second plate 203, thereby enabling the detection and analysis of the water sample.

[0049] Since one end of the first pull rod 501 extends into the sleeve 204, the sealing environment of the second plate 203 will be disrupted. In one embodiment, the first pull rod 501 and the inner wall of the second plate 203 can be connected by a flexible waterproof layer. When water enters between the first plate 201 and the second plate 203, the flexible waterproof layer seals the gap between the first pull rod 501 and the second plate 203, preventing the water entering between the first plate 201 and the second plate 203 from leaking through the gap between the second plate 203 and the first pull rod 501, thus ensuring the effectiveness of water sample collection.

[0050] In one embodiment, the flexible layer 202 and the flexible waterproof layer can be a rubber layer or a waterproof fabric layer, and there is no limitation on this.

[0051] In one embodiment, the first elastic element 207, the second elastic element 401, and the third elastic element 502 can be springs or metal sheets, and there is no limitation here.

[0052] In one embodiment, the air supply component may be an airbag or a plunger pump, and there is no limitation on this.

[0053] In this embodiment of the invention, during hydrological surveys and water source collection, the connecting pipe 10 can be manipulated so that the counterweight 30 pulls the connecting pipe 10 into the water body. At this time, the flexible collection component 20 enters the water body along with the connecting pipe 10. During this process, the limiting component 50 restricts the flexible collection component 20 to a compressed state, thereby reducing the volume of the flexible collection component 20 and reducing the resistance when the flexible collection component 20 enters the water body. When the flexible collection component 20 reaches a predetermined depth, air is supplied to the connecting pipe 10 through the air supply component to drive the connecting pipe 10 to expand and deform, thereby... The limiting component 50 is moved to release the restriction on the flexible acquisition component 20 in the compressed state. At this time, the flexible acquisition component 20 expands and deforms to draw water into the interior of the flexible acquisition component 20, thereby realizing the collection of water samples. Compared with the prior art, the volume of the flexible acquisition component 20 can be reduced during the process of the flexible acquisition component 20 entering the water body, thereby reducing resistance and ensuring that the flexible acquisition component 20 can smoothly enter the water body. When the flexible acquisition component 20 reaches the predetermined depth of the water body, it can realize the automatic collection of water samples, which has the advantages of good water sample collection effect and high collection efficiency.

[0054] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
