Description

Technical Field

[0001] The invention belongs to the technical field of sample collection and relates to a water quality sampling device, in particular to an ocean water quality sampling device. Background Art

[0002] The total ocean area on the earth's surface is about 360 million square kilometers, accounting for about 71% of the earth's surface area. The deep sea is rich in oil, natural gas and other oil and gas resources. It is the largest potential strategic resource base on the earth that has not yet been fully recognized and utilized by humans. With the rapid economic development of coastal cities, the problem of environmental pollution in nearshore waters has become increasingly prominent. Inorganic nitrogen, phosphates, heavy metals, etc. are exceeding the standard, and the water body is in a state of eutrophication to a certain extent. Therefore, sampling seawater is the basic work of marine research.

[0003] After searching, it is found that a seawater sampling tank is disclosed in Chinese patent literature [Application No.: CN201720796727.4; Publication No.: CN206847990U]. This seawater sampling tank includes a sealed tank body with a cavity, characterized in that a partition is provided to separate the cavity into an air chamber and a seawater chamber from top to bottom; an air passage connecting the air chamber and the seawater chamber is provided on the outside of the tank body, and the air passage is provided with an air separation valve to control the opening and closing.

[0004] The device disclosed in this patent can maintain complete airtightness during the deep ocean collection process and keep the sample in situ. However, the device cannot cope with suspended matter around the device during the sampling process. If suspended matter blocks the sampling port, the staff will need to lift the device again to clean the suspended matter before sampling can be carried out, which increases the workload of the staff. In addition, during the ascent of the device, the lifting device needs to be used in conjunction with the device, which is very inconvenient. If manpower is used to extract the device, the workload of the staff will be increased, which will bring a burden to the staff. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a marine water quality sampling device, which can effectively push away the suspended matter around the sampling barrel body during sampling, and the device can generate rising power. With the guidance of a staff holding a rope, the device can be easily lifted out of the water, and after being lifted out of the water, the foreign matter can be handled by a processing mechanism as a cleaning mechanism.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A marine water quality sampling device comprises a sampling barrel body, a force-bearing block is fixed on the top of the sampling barrel body, a hook is fixed on the top of the force-bearing block, a chassis is fixed on the lower side of the sampling barrel body, a waterproof cover is provided in the inner cavity of the chassis, a power mechanism is provided in the inner cavity of the chassis, a cleaning mechanism for clearing away suspended matter is provided on the lower side of the power mechanism, a propulsion mechanism for providing rising power is fixed on the lower side of the cleaning mechanism, and a processing mechanism is provided on the top of the sampling barrel body.

[0008] The working principle of the present invention is: a rope is installed on the hook, and the device is placed vertically in the ocean. When the target water depth is reached, the staff uses a power mechanism to provide power to the cleaning mechanism through a built-in signal, and the cleaning roller starts to revolve around the sampling barrel body. The rotation of the cleaning roller can avoid the sampling port being blocked by suspended matter. After the sampling is completed, the propulsion mechanism is powered by the power mechanism. At this time, the device can be lifted using a rope. After the device rises to the water surface, the staff pulls out the pin in the connecting block, and the staff uses the processing mechanism to remove foreign matter entangled on the brush for the next use.

[0009] The center of the force-bearing block and the center of the sampling barrel body are on the same vertical line, and the center of the hook claw and the center of the force-bearing block are on the same vertical line.

A protrusion is fixed on the upper surface of the second connecting disk. The protrusion and the groove fit together.

[0012] The above structure is adopted to provide power for the propulsion mechanism and the cleaning mechanism.

[0013] The working range of the hydraulic rod output shaft is equal to the distance between the first connecting plate and the second connecting plate, and when the output shaft path of the hydraulic rod is the largest, the bottom surface of the driving gear and the bottom surface of the second connecting plate are in the same plane.

[0014] The above structure is adopted to enhance the stability of the connection of each structure in the power mechanism.

[0015] The cleaning mechanism includes a connecting block, and the number of the connecting blocks is four, and the connecting blocks are fixed to the side of the first connecting plate. A vertical groove is provided on the surface of the upper side of the connecting block, and a transverse groove is provided through the inner cavity of the connecting block. A pin body is slidably provided in the inner cavity of the transverse groove, and a fixed foot is slidably provided on the surface of the vertical groove. A pin hole is provided on the surface of the fixed foot. A cleaning roller is fixed on the top of the fixed foot, and a plurality of brushes are fixed on the surface of the cleaning roller.

[0016] The above structure is adopted to clean the suspended matter around the sampling barrel body.

[0017] The brush is made of flexible material and fits the surface of the sampling barrel body.

[0018] With the above structure, the surface of the sampling barrel body is simply cleaned.

[0019] The outer diameter of the pin body is equal to the inner diameter of the transverse groove, and the outer diameter of the pin body is equal to the inner diameter of the pin hole.

[0020] The above structure makes the fit between the pin body, the transverse groove and the pin body more compact.

A protective cover is arranged around the fan blades. The protective cover is fixed to the lower surface of the second connecting disk. A plurality of openings are opened on the surface of the protective cover.

[0022] The above structure is adopted to provide the ascending power for the device.

[0023] The processing mechanism includes a lower plate, which is slidably connected to the surface of the sampling barrel body, the surface of the lower plate is provided with a plate hole, the surface of the plate hole is fixed with barbs, an upper plate is arranged on the upper side of the lower plate, the upper plate is fixedly connected to the top of the cleaning roller, and a handle is fixed on the top of the upper plate.

[0024] The above structure is adopted to clean foreign matters entangled on the surface of the brush.

[0025] The number of the handles is two and they are symmetrical about the center of the upper plate.

[0026] The above structure is adopted to maintain the overall symmetry of the device.

[0027] Compared with the existing technology, this ocean water quality sampling device has the following advantages:

[0028] 1. The present invention can effectively push away the suspended matter around the sampling barrel body during the collection process through the cooperation of the power mechanism and the cleaning mechanism to prevent the suspended matter from blocking the collection port of the sampling barrel body.

This solves the problem that during the sampling process of the current ocean water sampling device, the sampling failure may be caused by the presence of suspended matter around the device, and the lifting process of the sampling device requires the cooperation of the lifting device or is very laborious.

[0029] 2. The present invention can balance the force on the sampling barrel body when extracting the sampling barrel body, thereby avoiding the inconvenience caused by the sampling barrel body tilting in the middle due to the unbalanced force on the sampling barrel body.

[0042] like Figure 1-Figure 9 As shown, the present marine water quality sampling device comprises a sampling barrel body 1, a force-bearing block 2 is fixed on the top of the sampling barrel body 1, a hook 3 is fixed on the top of the force-bearing block 2, a chassis 9 is fixed on the lower side of the sampling barrel body 1, a waterproof cover 4 is arranged in the inner cavity of the chassis 9, a power mechanism 5 is arranged in the inner cavity of the chassis 9, a cleaning mechanism 7 for removing suspended matter is arranged on the lower side of the power mechanism 5, a propulsion mechanism 6 for providing rising power is fixed on the lower side of the cleaning mechanism 7, and a processing mechanism 8 is arranged on the top of the sampling barrel body 1. The present invention can effectively remove the suspended matter of the sampling barrel body 1 through the cooperation of the power mechanism 5 and the cleaning mechanism 7 during the collection process. The suspended matter around the body 1 is prevented from clogging the collection port of the sampling barrel body 1 by the suspended matter, and after the sampling of the device is completed, the power mechanism 5 and the propulsion mechanism 6 can cooperate to provide the device with rising power. Under the guidance of the staff holding the rope, the device can be easily lifted out of the water, and after being lifted out of the water, the cleaning mechanism 7 can be used to handle foreign matter through the processing mechanism 8, which is convenient for next use. This solves the problem that the sampling process of the current ocean water sampling device may fail due to the presence of suspended matter around the device, and the problem that the lifting device needs to cooperate with the lifting device or manpower is very laborious during the lifting process of the sampling device.

[0043] The center of the force block 2 is on the same vertical line as the center of the sampling barrel body 1, and the center of the hook 3 is on the same vertical line as the center of the force block 2. In this embodiment, by setting the center point positions of the force block 2, the hook 3 and the sampling barrel body 1, it is convenient to balance the force of the sampling barrel body 1 when extracting the sampling barrel body 1, avoiding the trouble caused by the sampling barrel body 1 tilting in the middle due to the unbalanced force on the sampling barrel body 1.

[0044] The power mechanism 5 includes a hydraulic rod 501, which is fixed to the top of the inner cavity of the chassis 9. A motor 502 is fixed to the output end of the hydraulic rod 501. The surface of the motor 502 is fixedly connected to the waterproof cover 4. A driving gear 503 is fixed to the output shaft of the motor 502. A first connecting disk 504 is provided on the surface of the driving gear 503. The first connecting disk 504 is rotatably connected to the bottom of the chassis 9. A first inner tooth 507 is provided in the middle of the first connecting disk 504. A groove 509 is fixed on the lower surface of the first inner tooth 507. A second connecting disk 506 is slidably provided on the lower side of the groove 509. A second inner tooth 508 is provided in the middle of the second connecting disk 506. A protrusion 505 is fixed on the upper surface of the second connecting disk 506, and the protrusion 505 is fitted with the groove 509. In the present embodiment, by arranging the hydraulic rod 501, the motor 502, the driving gear 503, the first connecting disk 504, the protrusion 505, the second connecting disk 506, the first inner teeth 507, the second inner teeth 508 and the groove 509, it is convenient to provide power for the propulsion mechanism 6 and the cleaning mechanism 7. By turning on the motor 502, the driving gear 503 rotates under the operation of the motor 502, and by adjusting the position of the output shaft of the hydraulic rod 501, the corresponding structure meshing with the driving gear 503 is changed, thereby achieving different purposes.

[0045] The working range of the output shaft of the hydraulic rod 501 is equal to the distance between the first connecting disk 504 and the second connecting disk 506, and when the output shaft path of the hydraulic rod 501 is the largest, the bottom surface of the driving gear 503 and the bottom surface of the second connecting disk 506 are in the same plane. In this embodiment, by setting the working range of the hydraulic rod 501, it is convenient to enhance the stability of the connection of each structure in the power mechanism 5, and avoid the problem of poor meshing between gears due to the large working range of the hydraulic rod 501, which causes the power mechanism 5 to idle.

[0046] The cleaning mechanism 7 includes a connecting block 703, the number of which is four, and the connecting block 703 is fixed to the side of the first connecting plate 504, a vertical groove 704 is provided on the surface of the upper side of the connecting block 703, a transverse groove 705 is provided through the inner cavity of the connecting block 703, a pin body 706 is slidably provided in the inner cavity of the transverse groove 705, a fixed foot 707 is slidably provided on the surface of the vertical groove 704, a pin hole 708 is provided on the surface of the fixed foot 707, a cleaning roller 702 is fixed on the top of the fixed foot 707, and the cleaning roller 702 is fixed on the top of the cleaning roller 702. 02 is fixed with a plurality of brushes 701. In the present embodiment, by arranging the brushes 701, the cleaning roller 702, the connecting block 703, the vertical groove 704, the horizontal groove 705, the pin body 706, the fixing foot 707 and the pin hole 708, it is convenient to clean the suspended matter around the sampling barrel body 1 during the sampling process of the sampling barrel body 1. The first connecting disk 504 connected to the connecting block 703 provides power to make the cleaning roller 702 revolve around the sampling barrel body 1, so as to remove the suspended matter around the sampling barrel body 1.

[0047] The brush 701 is made of a flexible material, and the brush 701 fits the surface of the sampling barrel body 1. In this embodiment, by setting the material and position of the brush 701, the surface of the sampling barrel body 1 can be simply cleaned when the brush 701 moves, and the material of the brush 701 is flexible and will not cause damage to the surface of the sampling barrel body 1.

[0048] The outer diameter of the pin body 706 is equal to the inner diameter of the transverse groove 705, and the outer diameter of the pin body 706 is equal to the inner diameter of the pin hole 708. In the present embodiment, by setting the specifications of the pin body 706, the transverse groove 705 and the pin body 706, it is convenient to make the pin body 706, the transverse groove 705 and the pin body 706 fit more compactly, and avoid shaking during rotation due to the existence of pores after connection, which affects the overall stability of the device. The limit on the fixed foot 707 can be released through the pin body 706, so as to disassemble the cleaning roller 702, and then facilitate the subsequent foreign matter removal work of the brush 701.

[0049] The propulsion mechanism 6 includes a connecting member 601, which is fixed to the lower surface of the second connecting disk 506. The lower surface of the connecting member 601 is fixed with fan blades 602. A protective cover 603 is arranged around the fan blades 602. The protective cover 603 is fixed to the lower surface of the second connecting disk 506. A plurality of openings 604 are provided on the surface of the protective cover 603. In the present embodiment, by arranging the connecting member 601, the fan blades 602, the protective cover 603, and the openings 604, it is convenient to provide the device with rising power through the cooperation of the power mechanism 5 and the propulsion mechanism 6 when lifting the sampling barrel body 1, thereby increasing the lifting speed of the sampling barrel body 1 and reducing the time the sampling barrel body 1 is in the water.

[0050] The processing mechanism 8 includes a lower plate 805, which is slidably connected to the surface of the sampling barrel body 1. A plate hole 803 is opened on the surface of the lower plate 805, and a barb 804 is fixed on the surface of the plate hole 803. An upper plate 802 is arranged on the upper side of the lower plate 805. The upper plate 802 is fixedly connected to the top of the cleaning roller 702, and a handle 801 is fixed on the top of the upper plate 802. In this embodiment, by providing the handle 801, the upper plate 802, the plate hole 803, the barb 804 and the lower plate 805, it is convenient to clean the foreign matter entangled on the surface of the brush 701 under the action of the barb 804 by moving the cleaning roller 702 up and down after the sampling is completed.

[0051] There are two handles 801, which are symmetrical about the center of the upper plate 802. In this embodiment, by setting the number and position relationship of the handles 801, it is convenient to maintain the overall symmetry of the device, improve the stability of the device moving in water, and provide a force point for the staff during the lifting process of the cleaning roller 702.

[0052] The working principle of the present invention is as follows: before use, the staff installs the rope on the hook 3, and then after arriving at the sampling water area, the staff places the device vertically in the ocean and slowly descends with the cooperation of the rope. When reaching the target water depth, through the built-in signal, the staff uses the power mechanism 5 to adjust the position of the output shaft of the hydraulic rod 501 to make the active gear 503 mesh with the first internal tooth 507, and turns on the motor 502 to rotate the active gear 503, and the first connecting disk 504 connected to the first internal tooth 507 also starts to rotate, and the cleaning mechanism 7 starts to work with the help of the power mechanism 5. Under the connection of the connecting block 703, the cleaning roller 702 starts to revolve around the sampling barrel body 1, and the sampling barrel body 1 can be used to sample the target water depth. During the sampling process, the rotation of the cleaning roller 702 can clear away the suspended matter around the sampling barrel body 1 to avoid clogging the sampling port due to the suspended matter. After the sampling is completed, the cleaning roller 702 in the power mechanism 5 is used to clean the sampling barrel body 1. 501, and turn off the motor 502, so that the driving gear 503 is meshed with the second inner teeth 508. After the driving gear 503 is meshed with the second inner teeth 508, the motor 502 is turned on to drive the second connecting disk 506 to rotate, and the propulsion mechanism 6 connected to the second connecting disk 506 starts to work. Under the action of the second connecting disk 506, the connecting piece 601 and the fan blade 602 start to rotate, and the fan blade 602 generates a downward thrust in the water. At this time, the rope can be used to lift the device more labor-savingly, and with the cooperation of the propulsion mechanism 6, the moving speed of the device can be increased, so that the device begins to rise to the water surface. After the device rises to the water surface, the staff pulls out the pin body 706 in the connecting block 703, and the staff uses the processing mechanism 8. The staff can use the handle 801 to vertically lift the upper plate 802 and the cleaning roller 702, and under the action of the barb 804, remove the foreign matter entangled on the brush 701 for next use.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
