Description

Technical Field

[0001] The invention relates to the field of water sample collection equipment, in particular to a portable water quality sampling system for a water reservoir. Background Art

[0002] When sampling existing water bodies or deep water areas in reservoirs, a hose is generally used to penetrate into the water body. Sampling needs to be performed at a given depth, while understanding the mineral composition of the local water body or reservoir at that depth, the types of microorganisms in the water, etc. Since the hose itself has no support, when the hose penetrates into the water body, the sampling head or the tube body at the end of the hose may easily rub against other objects or the wall of the reservoir due to the water flow or the bending of the hose itself, causing mosses, silt, impurities, shallow water algae, etc. on the inner wall of the side originally located in shallow water to be brought to the given monitoring depth, affecting the monitoring results at the given depth. The use of all-steel pipes will result in the need to assemble multiple steel pipes on site for sampling, which is very time-consuming and labor-intensive. Summary of the invention

[0003] Aiming at the problem in the prior art that a sampling hose is prone to hit a wall, thus affecting the sampling result, the present invention provides a portable water quality sampling system for a water reservoir.

[0004] In order to solve the above technical problems, the present invention is solved through the following technical solutions: a portable water quality sampling system for a water storage tank, comprising a collection hose, a winding device for winding the collection hose, and a hose support assembly, wherein the hose support assembly is composed of a plurality of hard support members, the hard support members are evenly spaced on the collection hose, the hard support members are slidably matched with a locking member, the locking member comprises a floating portion in a cavity shape and a locking portion 1, the hard support member is provided with a locking portion 2 matched with an adjacent locking portion 1, when the collection hose vertically enters the water, the floating portion drives the locking member to float up under the action of buoyancy, the locking portion 1 of the locking member is locked and matched with the locking portion 2 of the adjacent hard support member, when the collection hose leaves the water body, the locking member is driven downward by gravity, and the locking member is separated from the adjacent hard support member;

[0005] The water sampling equipment also includes an in-place detection module, wherein the locking part one or the locking part two is provided with a color mark, and when the locking part one is fully matched with the locking part two of the adjacent rigid support member, the color mark of the locking part two or a pair of locking parts is completely covered, and when the locking part one is not matched with the locking part two of the adjacent rigid support member, the color mark is not covered, and when the locking hole part is matched with the locking pin of the adjacent rigid support member, the color mark is partially covered; the in-place detection module includes an image acquisition unit, and the image acquisition unit includes an image acquisition device for acquiring an image to be tested; a comparison unit, which stores a standard acquisition image, and generates matching covering information by comparing the covering degree of the color mark in the standard acquisition image and the image to be tested; a generation unit, which generates an unlocking signal, a partial locking signal and a full locking signal according to the matching covering information; and the winding device stops the pipe releasing operation according to the unlocking signal.

[0006] By adopting the above technical scheme, in order to solve the problem that when using traditional hoses for sampling, the hoses are difficult to control and will cause scratches and collisions with the inner wall of the reservoir, causing other algae and silt impurities originally located in shallow water to be brought to a given detection depth. When water sampling is carried out at a given depth, the sampling result at a given depth will be affected. A hard support piece is provided on the original collection hose. When the locking piece slidingly connected in the collection hard support piece is under the action of the floating part in a cavity state, the entire locking piece is in a floating state, thereby driving the locking piece and the locking part 2 of the adjacent hard support piece above to be in a coordinated state, so that the hard support piece and the adjacent hard support piece above are in a locked state, the hard support piece enters the water body once, thereby being locked once, and the hard support piece is connected to the adjacent hard support pieces in sequence through the locking piece, so that the support piece entering the water forms a long outer support strip, thereby restricting the collection hose and avoiding the collection softness. The tube collides with other objects due to its own material, and the end of the collection hose can also reach the given collection depth more accurately like a hard tube. When the collection is completed, the reeling device reels the collection hose. After the hard support part on the collection hose leaves the water body, the floating part loses its buoyancy, and the locking part moves downward under the action of its own gravity, thereby driving the hard support part to separate from the adjacent hard support part. After the hard support part separates from the hard support part, the reeling device completes the reeling of the collection hose by utilizing the bendable characteristics of the collection hose, and detects the locking part that has entered the water through the in-place detection module. When it is detected that the locking pin after entering the water has not entered the locking hole of the adjacent hard support part, the operation is stopped for subsequent maintenance to avoid the inability to form a complete support for the collection hose due to the failure of a certain locking part to cooperate. The in-place detection module is used to facilitate timely detection of problems.

[0007] The present invention is further configured as follows: the locking part one is in the shape of a hole or a column, the locking part two is in the shape of a column or a hole that cooperates with the locking part one, the columnar locking part one and the columnar locking part two are locking pins, the hole-shaped locking part two and the hole-shaped locking part one are locking holes, and the color marking is applied to the locking pin.

[0008] By adopting the above technical solution, the columnar structure and the hole structure are more compact than the baffle mode.

[0009] The present invention is further configured as follows: the floating portion is provided with a depth mark, and the depth mark is used to mark the distance from the rigid support member to the end of the collection hose.

[0010] By adopting the above technical solution, the water entry depth of the collection hose of the floating part can be judged by the depth mark. Due to the existence of the hose support assembly, the hose will not float around, making the depth mark meaningful.

[0011] The present invention is further configured as follows: the in-place detection module also includes a storage unit, the image acquisition unit and the generation unit are both connected to the storage unit, and when the generation unit generates an unlocked signal and a partially locked signal, the storage unit stores the current image to be tested according to the unlocked signal or the partially locked signal, and the image to be tested includes a depth mark.

[0012] By adopting the above technical solution, the unlocked signal or partial locked signal stores the current image to be tested, which is convenient for replacing the locking part after the sampling is completed. The depth mark on the locking part is convenient for the operator to quickly find the corresponding defective locking part that cannot float or completely floats.

[0013] The present invention is further configured as follows: the reeling device is provided with a floating fixing piece in cooperation, the floating fixing piece is provided with a guide hole for the collection hose to pass through, and the guide hole is opened perpendicular to the water surface.

[0014] By adopting the above technical solution, after the collecting hose and the hard support member vertically enter the water body under the action of the guide hole, it is convenient for the locking member to float vertically and cooperate with the hard support member.

[0015] The present invention is further configured as follows: the floating fixing member is provided with a pushing assembly cooperating with the hose supporting assembly, the pushing assembly includes a pushing member and a power member for driving the pushing member to reciprocate, the pushing member is provided with a pushing slope for cooperating with the locking member, when the generating unit generates an unlocking signal, the power member drives the pushing member to move toward the locking member generating the unlocking signal, the pushing slope abuts against the locking member and drives the locking part 2 of the adjacent hard supporting member of the locking part 1 to cooperate, and the pushing slope drives the locking hole to completely cover the color marking of the locking pin.

[0016] By adopting the above technical solution, the locking member that generates an unlocked signal or a partial locked signal is unable to complete autonomous movement due to buoyancy for various reasons. The power member drives the push member to move, and the pushing slope of the push member abuts against the locking member, driving the locking member to move in the direction of the locking member of the adjacent hard support member, driving the locking member and the locking space to form a full locking setting.

[0017] The present invention is further configured as follows: a limiting member is provided for the sliding movement of the rigid support member, when the color identification is uncovered or partially covered, the locking member limits the sliding movement of the limiting member, and when the color identification is completely covered, the locking member does not limit the sliding movement of the limiting member, after the limiting member slides relative to the rigid support member, the limiting member abuts against one side of the locking member to limit the locking portion 1 from being separated from the locking portion 2 of the adjacent rigid support member, a magnetic member 1 is provided on the limiting member, and the pushing member is provided with a magnetic member 2 for attracting the magnetic member 1, and when the pushing slope drives the locking hole to completely cover the color identification of the locking pin, the magnetic member 2 is opposite to the magnetic member 1, and the pushing member resets to drive the limiting member to move.

[0018] By adopting the above technical solution, the locking parts that generate unlocked signals or partial locked signals and cannot actively float up or can only partially float up due to various reasons are actively locked through the limit members, in order to avoid the locking part one and the locking part two being separated due to jamming or insufficient buoyancy of these locking parts when in working state.

[0019] The present invention is further configured as follows: the guide hole is provided with a magnetic component three for attracting the magnetic component one, and when the magnetic component three and the magnetic component one are in a mutually attractive state relative to each other, the limiting component is controlled by the sliding of the magnetic component three and the limiting component is not arranged in contact with one side of the locking component.

[0020] By adopting the above technical solution, in order to solve the problem that the limit member cannot be actively reset after being sucked out by the magnet, resulting in difficulty in winding up, when the winding device recycles the collection hose, the magnetic member three attracts the magnetic member one to complete the reset of the limit member, so that the locking member and the locking part two are separated under the action of their own gravity.

[0021] The present invention is further configured as follows: an independent collection component is provided at the end of the collection hose, and the independent collection component includes a fixed seat, a collection seat connected to the fixed seat, and a sampling bottle, the fixed seat is fixedly connected to the hard support piece at the end of the collection hose, the collection seat is detachably connected to the sampling bottle, a sampling hole is opened on the collection seat, the sampling hole is communicated with the sampling bottle, and the collection seat is provided with a valve sheet for opening or closing the sampling hole.

[0022] By adopting the above technical solution, in order to avoid the influence of impurities in the sampling tube on the sampling results, an independent sampling component is set at the end of the sampling hose. While sampling the sampling tube, the stability of the hard support can be used to perform independent sampling at a given depth.

[0023] The present invention is further configured as follows: the valve plate is pivotally connected to the collection seat, the valve plate is provided with a torsion spring, the torsion spring is used to drive the valve plate to a closed state relative to the collection hole, the valve plate is connected to a pull rope, the movement of the pull rope can drive the valve plate to an open state relative to the collection hole, and the hard support members are provided with through holes for passing the pull rope.

[0024] By adopting the above technical solution, in order to solve the collection control problem, in the case of support from a hard support, the valve plate can be opened by manually or electrically pulling the pull rope. When the valve plate is opened, under the action of water pressure, the water sample at the position of the independent collection component enters the sampling bottle through the sampling hole. After loosening the pull rope, the valve plate is reset and the sampling hole is reclosed under the action of the torsion spring. When the sampling water pipe is recovered, water samples at other positions are prevented from entering the sampling bottle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Embodiment 1:

[0033] A portable water quality sampling system for a water storage tank, first see Figure 1 , including a collection hose 1, a reeling device 2 for reeling in the collection hose 1, a hose supporting assembly 3 and an independent collection assembly 4. The reeling device 2 includes a reeling base 21, a reeling wheel 22 and a reeling motor 23. The collection hose 1 is a hose designed to be wound around the reeling wheel 22. The reeling motor 23 can drive the reeling wheel 22 to rotate. The rotation of the reeling wheel 22 can play a role in releasing or collecting the tube. The collection hose 1 is connected to a collection water pump.

[0034] See also Figure 1 and Figure 2 The hose support assembly 3 is arranged on the collection hose 1. The hose support assembly 3 is used to drive the collection hose 1 to play a supporting role after entering the water. The collection hose 1 has support after entering the water to avoid collision with the side wall of the collection well or other objects like a hard pipe, causing turbidity of the water body to affect the detection of the water body at a given depth. It can also prevent the hose from being twisted or shaken left and right due to water flow like a traditional hose after entering the water, and cannot accurately reach the detection depth.

[0035] See also Figure 1 and Figure 2The hose support assembly 3 includes a plurality of hard support members 31 and a plurality of locking members 32, each of which is provided with a locking member 32, and the plurality of hard support members 31 are evenly spaced on the collection hose 1, and the hard support member 31 includes a connecting portion 311 and a supporting portion 312, the connecting portion 311 is annularly sleeved on the hose and is provided by fixing adhesive, and the supporting portion 312 is in the form of a sheet in this embodiment, but is not limited to a sheet and may also be in the form of a ring or an arc with the hose as the center. The supporting portion 312 in this embodiment is in the form of a square sheet and is made of hard plastic, and a locking portion 313 cooperating with the locking member 32 is provided on the supporting portion 312, and the locking member 32 is slidably provided on the side of the supporting portion 312 away from the connecting portion 311, and the locking member 3 2 includes a floating portion 321 and a locking portion 1 322. The floating portion 321 is a hollow cavity structure without an opening. In this embodiment, the locking portion 1 322 is a hole-shaped locking hole. The locking hole formed by the locking portion 1 322 is opened on the floating portion 321, but the locking hole formed by the locking portion 1 322 is a countersunk hole. The floating portion 321 is a hollow cavity structure without an opening. The locking portion 2 313 is a columnar structure matched with the locking portion 1 322 in this embodiment. The locking portion 1 322 of the columnar structure forms a locking pin. In this embodiment, two cylindrical locking pins are provided, but it is not limited to two and can also be one or more. Two locking holes are provided on the locking member 32. The two locking pins are respectively provided with the two locking holes. The locking pin is a solid structure.

[0036] See also Figures 1 to 3 A sliding assembly is provided on the support portion 312, and the sliding assembly includes a sliding rail fixedly connected to the hard support member 31 by screws and a sliding block connected to the locking member 32. Limit screws are provided at both ends of the sliding rail on the support portion 312, and the limit screws are used to limit excessive sliding of the sliding block. The floating portion 321 is detachably connected to the sliding block, and the floating portion 321 is threadedly connected to the sliding block by screws. The purpose of the threaded connection by screws is that when part of the floating portion 321 cannot float due to deformation or breakage, the screws can be removed to replace a good locking member 32.

[0037] When the winding device 2 is in the tube releasing state, the rigid support members 31 of the hose support assembly 3 enter the water in turn, and the floating portion 321 after entering the water forms buoyancy in the water, driving the locking member 32 to float up, and the locking portion 1 322 of the locking member 32 is matched with the locking portion 2 313 of the upper adjacent rigid support member 31. When the winding device 2 is in the tube reeling state, the rigid support members 31 of the hose support member exit the water in turn, and the floating portion 321 after exiting the water has no buoyancy in the water, so that the floating member descends under the action of its own gravity, so that the locking portion 1 322 is separated from the adjacent locking portion 2 313.

[0038] See also Figure 1 and Figure 3A floating fixing part 24 can be pivotally or detachably connected to the winding base 21, and the winding device can be placed on the shore or a supported boat, and the floating fixing part 24 can be removed and placed on the water surface. The floating fixing part 24 adopts a hollow cavity structure or a material that can float on the water surface. A guide column 241 is protruding from the floating fixing part 24, and the guide column 241 is partially set underwater. The guide column 241 has a guide hole 242 for the collection hose 1 to pass through, and the guide hole 242 is opened perpendicular to the water surface. Guide bars 314 are protruding on both sides of the hard support part 31, and the guide hole 242 has a guide groove 243 for sliding cooperation with the guide bar 314. The length direction of the guide groove 243 is parallel to the circumferential direction of the center of the guide hole 242. The setting of the guide column 241 is to facilitate the hard support part 31 to enter the water in a direction perpendicular to the water surface, so that the locking part 32 after entering the water can float and cooperate with the hard support part 31 above.

[0039] In this embodiment, the locking portion 1 322 adopts a locking hole structure, and the locking portion 2 313 adopts a locking pin structure. A color mark 33 is applied on the columnar locking portion 2 313. When the locking portion 1 322 and the locking portion 2 313 of the adjacent rigid support member 31 are fully matched, the locking pin is in a state of fully entering the locking hole, and the locking hole completely covers the color mark 33 of the locking pin. When the locking portion 1 322 is not matched with the locking portion 2 313 of the adjacent rigid support member 31, the locking pin is in a state of fully entering the locking hole, and the locking hole completely covers the color mark 33 of the locking pin. When mating, the locking hole does not cover the color mark 33 of the locking pin. When the locking hole partially matches with the locking pin of the adjacent hard support member 31, the locking hole partially covers the color mark 33 of the locking pin. After entering the water, the locking hole does not cover or partially covers the color of the locking pin. The reason may be that the floating part 321 may be damaged or overweight, resulting in insufficient buoyancy, so that the locking member 32 cannot be matched with the hard support member 31 adjacent to the water surface.

[0040] The water body sampling device further includes an in-place detection module 6 , which includes an image acquisition unit 61 , a comparison unit 62 , a generation unit 63 and a storage unit 64 .

[0041] The image acquisition unit 61 includes an image acquisition device for acquiring the image to be tested; the comparison unit 62 generates matching masking information by comparing the length of the color mark 33 in the standard acquisition image and the image to be tested, and the comparison unit 62 stores the standard acquisition image; the generation unit 63 generates an unlocking signal, a partial locking signal and a full locking signal according to the matching masking information; the image acquisition unit 61 and the generation unit 63 are both connected to the storage unit 64, and when the generation unit 63 generates an unlocking signal and a partial locking signal, the storage unit 64 stores the current image to be tested according to the unlocking signal or the partial locking signal, and the floating part 321 is provided with a depth mark 34, and the depth mark 34 is used to identify the distance from the hard support member 31 to the end of the collection hose 1, and the image to be tested includes the depth mark 34. The depth mark 34 can be used to judge the water entry depth of the collection hose 1 of the floating part 321, and the winding device 2 stops the pipe laying operation according to the unlocking signal.

[0042] The floating fixing member 24 is provided with a pushing assembly 5 that cooperates with the hose supporting assembly 3. The pushing assembly 5 includes a pushing member 51 and a power member 52 for driving the pushing member 51 to reciprocate. In this embodiment, the power member 52 adopts an electric push rod, but is not limited to a linear motor. Standard parts for linear motion such as cylinders and linear motors can also be used. The pushing member 51 is a trapezoidal block and is provided with a pushing slope 53 that cooperates with the locking member 32. The power member 52 is covered with a waterproof shell, and the waterproof shell is fixedly connected to the floating fixing member 24. When the generating unit 63 generates an unlocking signal, the power member 52 drives the pushing member 51 to move toward the locking member 32 that generates the unlocking signal, and the pushing slope 53 abuts against the locking member 32 and drives the locking part 2 313 of the adjacent hard support member 31 of the locking part 1 322 to cooperate, and the pushing slope 53 drives the locking hole to completely cover the color mark 33 of the locking pin.

[0043] The rigid support member 31 is provided with a sliding hole 54, in which a rod-shaped limiting member 55 is slidably arranged. The sliding direction of the limiting member 55 is perpendicular to the sliding direction of the locking member 32. When the locking portion 1 322 and the locking portion 2 313 are not matched or partially matched, that is, when the color mark 33 is not covered or partially covered, the locking member 32 blocks the limiting member 55 to prevent the limiting member 55 from extending. When the locking portion 1 322 and the locking portion 2 313 are fully matched, the locking pin is When the locking hole is fully entered, the color marking 33 is completely covered. At this time, the locking member 32 does not restrict the movement of the limiting member 55, but when the limiting member 55 partially extends out of the sliding hole 54, the limiting member 55 forms a limit on the locking member 32, which can restrict the movement of the locking member 32, thereby avoiding the locking part 1 322 from being separated from the adjacent locking part 2 313, and avoiding the locking part 32 that is pushed into place by the pushing assembly 5 due to damage to the floating part 321, and the locking part 1 322 is separated from the adjacent locking part 2 313 after entering the water.

[0044] To facilitate the extension of the limit member 55, a magnetic member 56 is fixedly connected at both ends of the limit member 55, and the push member 51 is provided with a magnetic member 57 for attracting the magnetic member 56. When the push member 51 drives the locking portion 322 of the abnormal locking member 32 to fully cooperate with the locking portion 313 of the adjacent hard support member 31 through the pushing slope 53, the magnetic member 2 and the magnetic member 1 form a mutual adsorption state. When the power member 52 drives the push member 51 to reset, the push member 51 drives the limit member 55 to move synchronously through the magnetic member 2 and the magnetic member 1. The limit member 55 is in an I-shape, which can prevent the limit member 55 from moving excessively. After the limit member 55 moves into place, the push member 51 continues to reset and moves the magnetic member 1 and the magnetic member 2 to automatically disengage from the setting, thereby completing the extension of the limit member 55.

[0045] When the winding device 2 is in the tube winding state, in order to avoid the limiting position of the locking member 32 by the limiting member 55, which causes the locking member 32 to be unable to disengage from the adjacent hard support member 31, a magnetic attraction member 3 58 is arranged in the lead-out hole of the guide column 241, and the magnetic attraction member 1 56 at the end of the limiting member 55 away from the pushing member 51 is arranged opposite to the magnetic attraction member 3 58. When the magnetic attraction member 3 58 is opposite to the magnetic member 1 at the end of the limiting member 55, the magnetic member 3 and the magnetic member form a mutual attraction to drive the limiting member 55 to reset. When the limiting member 55 is retracted into the sliding hole 54, the limiting member 55 does not interfere with the locking member 32, so that the locking member 32 can be disengaged from the adjacent hard support member 31. When the hard support member 31 moves out of the guide hole 242, it is convenient for the winding drum to be wound. The magnetic member 1, the magnetic member 2 and the magnetic member 3 in this embodiment are all magnets, but it is not limited to all using magnets. It is also possible to use magnets and iron blocks that can be attracted by magnets.

[0046] An independent collection component 4 is provided at the end of the collection hose 1, and the independent collection component 4 includes a fixed seat 41, a collection seat 42 connected to the fixed seat 41, and a sampling bottle 43. The fixed seat 41 is fixedly connected to the hard support member 31 at the end of the collection hose 1, and the collection seat 42 is detachably connected to the sampling bottle 43. In this embodiment, the collection seat 42 is provided with a threaded countersunk hole, and the sampling bottle 43 is provided with a threaded bottle mouth matching the threaded countersunk hole. A sampling hole 45 communicating with the threaded countersunk hole is provided on the collection seat 42, and the sampling hole 45 is communicated with the sampling bottle 43. The collection seat 42 is pivotally provided with a valve plate 44 for opening or closing the sampling hole 45, and a torsion spring is provided on the pivot shaft. The spring is used to drive the valve plate 44 to be in a closed state relative to the collection hole. A pull rope is connected to one end of the valve plate 44 away from the pivot joint. Movement of the pull rope can drive the valve plate 44 to be in an open state relative to the collection hole. A through hole for passing the pull rope is provided on the hard support member 31. When supported by the hard support member 31, the valve plate 44 can be opened by pulling the pull rope manually or electrically. When the valve plate 44 is opened, under the action of water pressure, the water sample at the position of the independent collection component 4 enters the sampling bottle 43 through the sampling hole 45. After the pull rope is loosened, the valve plate 44 is reset and the sampling hole 45 is reclosed under the action of the torsion spring. When the sampling water pipe is recovered, water samples at other positions are prevented from entering the sampling bottle 43.

[0047] Embodiment 2:

[0048] The difference between this embodiment and the first embodiment is that the locking portion 1 322 on the locking member 32 in this embodiment is in the shape of a raised column, which is a locking pin, and the locking portion 2 313 of the rigid support member 31 is in the shape of a countersunk hole, which is a locking hole.
