Description

Technical Field

[0001] The utility model relates to the technical field of undersea sand sampling, in particular to an underwater undersea sand sampling device. Background Art

[0002] Undersea sand is a natural resource in the ocean, mainly distributed in areas such as coasts, seabeds, river mouths, and bays. Undersea sand resources have high economic value and practical value, and are widely used in industries such as building materials, water conservancy projects, and glass manufacturing.

[0003] The utilization of undersea sand resources refers to the entire process of developing, processing, applying, and managing undersea sand resources. Undersea sand sampling is an important step in the utilization of undersea sand resources, aiming to ensure information such as the quality, applicability, composition, pollution status, and reserves of undersea sand, so as to better develop, utilize, and protect undersea sand resources.

[0004] After retrieval, the Chinese utility model patent with the publication number of CN212391230U discloses a sand cushion underwater sampler, which includes an inner core tube and an outer sleeve tube. The inner core tube is sleeved in the outer sleeve tube. The characteristics are as follows: the outer sleeve tube is a hollow steel pipe, and a plurality of groups of outer sleeve tube sampling round holes are spaced apart on the outer sleeve tube; the inner core tube is a solid round steel, and a plurality of groups of inner core tube sampling round holes are also spaced apart at corresponding positions to the outer sleeve tube. The lower part of the opening of the inner core tube sampling round hole is a hollow storage cavity. This application opens sampling holes on both the inner and outer hollow tubes, and realizes sampling and storage after sampling by controlling the alignment and misalignment of the two sampling holes respectively. However, the sampling process of this device requires divers to use a hammer to hammer the sampler into the sand layer at the bottom of the sea. This not only requires divers to exert extra physical strength, but also the existence of seawater resistance will affect the effect of swinging the hammer to strike, so the sampling of this device is inconvenient to use. Content of the Utility Model

[0005] Aiming at the above-mentioned prior art, the utility model aims to provide an underwater undersea sand sampling device, and the main technical problem to be solved is how to improve the convenience of underwater undersea sand sampling.

[0006] To achieve the above object, the technical solution of the embodiment of the utility model is realized as follows:

[0007] An underwater undersea sand sampling device includes a machine shell. Suction mechanisms and jet mechanisms are respectively arranged on both sides of the machine shell. The suction mechanism collects undersea sand by sucking water bodies. The suction mechanism includes a cover shell and a separation component. The separation component includes a separation box. A hose is fixedly connected between the separation box and the cover shell. A net plate is fixedly connected inside the separation box. The net plate is used for separating water and sand, and a plurality of elastic pieces are fixedly connected to one side of the net plate. The elastic pieces cause the net plate to vibrate through water flow. The jet mechanism is used for blowing away undersea sand, and the jet mechanism includes a nozzle.

[0008] Further, water inlets and outlets are respectively provided on both sides of the casing, and a water pump is arranged inside the casing. The water inlet end and the water outlet end of the water pump are respectively fixedly connected to the casing at the water inlets and outlets.

[0009] Further, the separation box is fixedly connected to the casing at the water inlet, and a pipe sleeve is fixedly connected between the separation box and the cover shell at the outside of the hose. The pipe sleeve is a metal shaped hose, and a handle is fixedly connected to the top end of the separation box.

[0010] Further, the net plate is obliquely arranged inside the separation box, and the net plate is in a state of tilting forward at the top end. A plurality of elastic pieces are fixedly connected to the lower side of the net plate in a staggered state, and the elastic pieces are in a state of tilting forward at the bottom end.

[0011] Further, a rectangular opening is provided at the bottom end of the separation box, and a collection box is fixedly connected to the bottom end of the separation box at the rectangular opening. A circular opening is provided at the bottom end of the collection box, and a collection cover is fixedly connected to the bottom end of the collection box at the circular opening. The collection cover is in a funnel shape.

[0012] Further, a threaded groove is provided at the outer top end of the collection cover, and a threaded sleeve is threadedly connected to the outside of the collection cover at the threaded groove. A net bag is fixedly connected to the outer bottom end of the threaded sleeve, and the net bag is at the outer bottom end of the collection cover.

[0013] Further, a connecting pipe is fixedly connected to the casing at the water outlet. The nozzle is sleeved on the outer part of one end of the connecting pipe, and a connecting rope is fixedly connected between the nozzle and the connecting pipe. The nozzle is in a conical shape.

[0014] Further, the elastic piece is in an arc shape, and a collection groove is provided at the middle part of the inner side of the elastic piece.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. When the device takes samples of sea sand, the water pump can respectively generate the effects of pumping water and draining water at the cover shell and the nozzle. Therefore, sea sand can be obtained by sucking seawater at the seabed, and after water-sand separation in the separation box, the sea sand enters the net bag to complete the collection. Therefore, the process of taking samples of sea sand underwater by this device will be more convenient; in addition, when the nozzle is installed on the connecting pipe, the water flow intensity can be increased by reducing the pipe diameter. Therefore, the surface sea sand can be washed away by using this water flow to facilitate sampling of deeper sea sand;

[0017] 2. By arranging a collection box and a collection cover at the bottom of the separation box, these two components can assist the sea sand to enter the mesh bag from the separation box. Since the diameters of both of them gradually decrease from top to bottom, it can ensure that the sea sand falls smoothly from top to bottom, and at the same time prevent the sea sand from returning to the separation box from bottom to top, thus ensuring the stability after the sea sand is collected. In addition, since the mesh bag is detachably installed outside the collection cover through a threaded sleeve, it is convenient to take out the sea sand after collection.

[0018] 3. By setting the elastic piece in an arc shape, the elastic piece in this form can block the water flow to a greater extent and cause greater turbulence of the water flow inside it, so as to cause greater vibration of the elastic piece, thereby enhancing the sand-water separation effect. In addition, the sea sand carried in the water flow hitting the elastic piece will move along the inner wall of the elastic piece with the water flow until it enters the collection groove, and then it will fall along the collection groove for easy collection of the sea sand.

[0027] Embodiment 1

[0028] Refer to the attached Figures 1-3, this application provides an underwater sea sand sampling device, including a machine shell 1. Suction mechanisms and jet mechanisms are respectively arranged on both sides of the machine shell 1. The suction mechanism collects sea sand by sucking water. When in use, only need to bring the cover shell 3 close to the surface of the sea sand, then the pumping effect of the water pump can be used to suck water. Along with the water fluctuation, the sea sand can move with the water flow and be sucked in, thus completing the collection of sea sand. The suction mechanism includes a cover shell 3 and a separation component. The separation component includes a separation box 5. A hose 401 is fixedly connected between the separation box 5 and the cover shell 3. Therefore, the orientation and angle of the cover shell 3 can be freely adjusted to adapt to the seabed environment. A mesh plate 10 is fixedly connected inside the separation box 5. The mesh plate 10 is used for water-sand separation. When the water pump sucks water, the mesh plate 10 can filter the water flow, so that the sea sand can be filtered out and collected, thus achieving the effect of collecting sea sand samples. And a number of elastic pieces 11 are fixedly connected to one side of the mesh plate 10. The elastic pieces 11 cause the mesh plate 10 to vibrate through the water flow. When the water flow passes through the mesh plate 10, the elastic pieces 11 can block the water flow. Therefore, the impact of the water flow on the elastic pieces 11 can cause them to deform, and then the elastic pieces 11 can return to their original state due to their own elasticity. This process occurs repeatedly, enabling the elastic pieces 11 to vibrate, thereby causing the mesh plate 10 to vibrate. Therefore, the sea sand blocked by the mesh plate 10 will not adhere to its surface but will be shaken off, thus facilitating collection. The jet mechanism is used to blow away the sea sand. The jet mechanism includes a nozzle 7. Due to the jet mechanism, the jet mechanism blows away the surface sea sand by jetting water flow. At this time, the deeper sea sand can be exposed for further collection.

[0029] Preferably, water inlets and outlets are respectively opened on both sides of the machine shell 1, and a water pump is arranged inside the machine shell 1. The water inlet end and the water outlet end of the water pump are fixedly connected to the machine shell 1 at the water inlet and the water outlet respectively. When the water pump operates, it can pump water from the water inlet end and drain water from the water outlet end at the same time. Therefore, it can respectively provide the pumping and spraying effects for the cover shell 3 and the nozzle 7.

[0030] Preferably, the separation box 5 is fixedly connected to the machine shell 1 at the water inlet. A pipe sleeve 4 is fixedly connected between the separation box 5 and the cover shell 3 outside the hose 401. The pipe sleeve 4 is a metal shaping hose. A handle 6 is fixedly connected to the top of the separation box 5. The metal shaping hose can maintain its current shape after being bent arbitrarily. Therefore, it can adjust the angle of the cover shell 3 and can achieve self-fixation in multiple angles and orientations.

[0031] Preferably, the screen plate 10 is inclined and arranged inside the separation box 5, and the screen plate 10 is in a state of inclining forward at the top. A plurality of elastic pieces 11 are fixedly connected to the lower side surface of the screen plate 10 in a staggered state, and the elastic pieces 11 are in a state of inclining forward at the bottom. The included angle between the screen plate 10 and the horizontal line is 45°-60°, and the included angle between the elastic piece 11 and the horizontal line is 60°-90°. In this state, the screen plate 10 and the elastic pieces 11 can prevent sea sand from staying on their surfaces, so it can promote the falling of sea sand and make its collection process more convenient.

[0032] Preferably, a rectangular opening is formed at the bottom end of the separation box 5, and a collection box 501 is fixedly connected to the bottom end of the separation box 5 at the rectangular opening. The collection box 501 is in an inverted trapezoidal shape. A circular opening is formed at the bottom end of the collection box 501, and a collection cover 502 is fixedly connected to the bottom end of the collection box 501 at the circular opening. The collection cover 502 is in a funnel shape. Since the diameters of both the collection box 501 and the collection cover 502 gradually decrease from top to bottom, it can not only make the falling of sea sand more concentrated, but also make it difficult for the sea sand that has entered the mesh bag 2 to return to the separation box 5. Therefore, it can prevent the collected sea sand from returning to the separation box 5 and affecting the collection efficiency.

[0033] Preferably, a threaded groove is formed at the outer top end of the collection cover 502, and a threaded sleeve 201 is threadedly connected to the outside of the collection cover 502 at the threaded groove. A mesh bag 2 is fixedly connected to the outside of the bottom end of the threaded sleeve 201. The mesh bag 2 is located at the outer bottom end of the collection cover 502. By turning the collection cover 502, the loading and unloading of the mesh bag 2 can be realized, so as to facilitate the replacement of the mesh bag 2 in the case of collecting different types of sea sand samples and the removal of the mesh bag 2 after the collection is completed.

[0034] Preferably, a connecting pipe 9 is fixedly connected to the housing 1 at the water outlet. The nozzle 7 is sleeved on the outside of one end of the connecting pipe 9, and a connecting rope 8 is fixedly connected between the nozzle 7 and the connecting pipe 9. The connecting rope 8 can connect the nozzle 7. When it is not installed on the connecting pipe 9, the connecting pipe 9 can drain water smoothly. When the nozzle 7 is installed on the connecting pipe 9, the water pressure can be enhanced by reducing the pipe diameter. At this time, the impact force of the water flow is greater. Therefore, the surface sea sand can be washed away by using this water flow to facilitate the collection of deeper sea sand. The nozzle 7 is in a conical shape.

[0035] Working principle: When using this device to take sea sand samples, a diver can hold the handle 6 to bring this device into the seabed. After bending the pipe sleeve 4 to align the housing 3 with the sea sand on the seabed, start the water pump in the housing 1. At this time, the operation of the water pump can respectively generate the effects of pumping water and draining water at the housing 3 and the connecting pipe 9. Therefore, the housing 3 will pump seawater, and the sea sand will be sucked into the hose 401 along with the water flow and finally transported into the separation box 5;

[0036] The sea sand entering the separation box 5 will impact the mesh plate 10 with the water flow, so that water and sand separation can be achieved, that is, the sea water is discharged from the connecting pipe 9, while the sea sand is blocked by the mesh plate 10, and because of its inclined state, the sea sand can fall; and when the water flow impacts the mesh plate 10, the water flow also acts on the spring piece 11, so the spring piece 11 will produce a slight vibration due to its own elastic force and the impact of the water flow, and the vibration can cause the mesh plate 10 to vibrate, so that the sea sand blocked by it can be caused to fall, and the falling sea sand will fall from the inner side of the collection box 501 and the collection cover 502 into the net bag 2 to complete the collection;

[0037] When it is necessary to collect deeper sea sand, the nozzle 7 can be put on the connecting pipe 9. At this time, the nozzle 7 can increase the water flow power by reducing the pipe diameter. Therefore, the water flow at the nozzle 7 can be used to disperse the surface sea sand, so that the deep sea sand is exposed for collection in the above manner.

[0038] When the net bag 2 needs to be replaced or removed, the threaded sleeve 201 can be turned to rotate, so that the threaded sleeve 201 can be removed from the outside of the collecting cover 502, thereby realizing the disassembly of the net bag 2.

[0039] Example 2

[0040] See attached Figure 4 The present application provides an underwater sea sand sampling device. Compared with Example 1, in order to further facilitate the collection of sea sand, the spring piece 11 is arc-shaped. In this state, when the water flow hits the spring piece 11, the water flow will continue to flow along the arc surface inside the spring piece 11, so the water flow can generate more complex turbulence on the inner side thereof, thereby causing the spring piece 11 to vibrate more, thereby inducing greater vibration of the mesh plate 10, thereby causing the sea sand blocked by the mesh plate 10 to fall, and a collecting groove 1101 is opened in the middle part of the inner side of the spring piece 11, and the collecting groove 1101 can collect sea sand in the above-mentioned water flow, so as to facilitate more complete collection of sea sand.

[0041] Working principle: When the water flow hits the shrapnel 11, the water flow will flow along the inner curved surface thereof, so the water flow will generate a greater degree of turbulence on the inner side of the shrapnel 11, thereby causing it to vibrate to a greater extent. In this case, the mesh plate 10 will also be able to generate a greater degree of vibration, thereby facilitating the collection of sea sand. In addition, when the water flow flows along the inner curved surface of the shrapnel 11, the sea sand it carries will also enter the collecting trough 1101, so the collecting trough 1101 can assist in capturing the sea sand and allow it to fall along the trough body in the collecting trough 1101, thereby further facilitating the collection of sea sand.

[0042] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the protection scope of the said claims.
