Abstract

The application discloses a portable water quality sampling system for water storage pools, which comprises a collecting hose, a winding device for winding the collecting hose and a hose supporting assembly. The hose supporting assembly is composed of a plurality of hard supporting members which are uniformly and spacedly arranged on the collecting hose. The hard supporting members are slidably matched with locking members. The locking members comprise a cavity-shaped floating part and a locking part I. The hard supporting members are provided with locking part II matched with the adjacent locking part I. When the collecting hose vertically enters water, the floating part drives the locking members to float under the action of buoyancy. The locking part I of the locking members is in locking and matched arrangement with the locking part II of the adjacent hard supporting member. When the collecting hose leaves the water body, the locking members are driven to move downward under the action of gravity.

The water body sampling device further comprises a position detection module for detecting whether the locking members and the hard supporting members are in position.

Description

Technical Field

[0001] This invention relates to the field of water sampling equipment, and more particularly to a portable water quality sampling system for water storage tanks. Background Technology

[0002] When sampling existing water bodies or deep water areas in reservoirs, flexible tubes are generally used to penetrate the water. Sampling is required at a given depth to understand the mineral composition and types of microorganisms at that depth. However, since the flexible tube itself is unsupported, the sampling head or tube body at the end of the tube may easily rub against other objects or the reservoir wall due to water flow or the bending of the tube itself. This can cause moss, silt, impurities, and algae in shallow water areas to be carried to the given monitoring depth, affecting the monitoring results at that depth. Using all-steel tubes would require the on-site assembly of multiple steel tubes, which is time-consuming and labor-intensive. Summary of the Invention

[0003] This invention addresses the problem in existing technologies where sampling hoses are prone to bumping against walls, thus affecting sampling results, by providing a portable water quality sampling system for water storage tanks.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a portable water quality sampling system for a water storage tank, comprising a sampling hose, a winding device for winding the sampling hose, and a hose support assembly. The hose support assembly is composed of several rigid support members, which are evenly spaced on the sampling hose. Each rigid support member is slidably fitted with a locking member. The locking member includes a hollow floating part and a locking part one. The rigid support member is provided with a locking part two that cooperates with the adjacent locking part one. When the sampling hose enters the water vertically, the floating part drives the locking member to float upward under the action of buoyancy. The locking part one of the locking member is locked in place with the locking part two of the adjacent rigid support member. When the sampling hose leaves the water, the locking member is driven downward under the action of gravity, and the locking member disengages from the adjacent rigid support member.

[0005] The water sampling equipment also includes a positioning detection module. The locking part one or locking part two is equipped with color markings. When locking part one is fully engaged with locking part two of an adjacent rigid support, the color markings are completely covered by locking part two or locking part one. When locking part one is not engaged with locking part two of an adjacent rigid support, the color markings are uncovered. When the locking hole partially engages with the locking pin of an adjacent rigid support, the color markings are partially covered. The positioning detection module includes an image acquisition unit, which includes an image acquisition device for acquiring the image to be tested; a comparison unit, which stores standard acquired images and generates engagement / coverage information by comparing the degree of coverage of the color markings in the standard acquired images and the image to be tested; and a generation unit, which generates unlocked signals, partially locked signals, and fully locked signals based on the engagement / coverage information. The winding device stops the pipe unwinding operation based on the unlocked signal.

[0006] By adopting the above technical solution, to address the problem of traditional flexible tube sampling where the tube is difficult to control and can scrape and collide with the inner wall of the reservoir, causing algae, silt, and other impurities originally located in shallow water to be carried to the given detection depth, thus affecting the sampling results at that depth, a rigid support is installed on the original sampling tube. When the locking part inside the rigid support is slidably connected, the entire locking part floats upward under the action of the hollow floating part, thereby driving the locking part to engage with the locking part of the adjacent rigid support above, thus locking the rigid support to the adjacent rigid support. The rigid support enters the water once and locks once. The rigid support is connected to the adjacent rigid support through the locking part, so that the support in the water forms a long strip of outer support, which can restrict the sampling tube and prevent soft sampling. Because of its material properties, the hose can collide with other objects, but this also allows the end of the collection hose to reach a given collection depth more accurately, similar to a rigid hose. When collection is complete, the winding device winds up the collection hose. After the rigid support on the collection hose leaves the water, the upper part loses buoyancy, and the locking member moves downward under its own weight, thus driving the rigid support member to detach from the adjacent rigid support member. After the rigid support member detaches from the rigid support member, the winding device winds up the collection hose using its flexible properties. The positioning detection module detects the locking member entering the water. If it detects that the locking pin after entering the water has not entered the locking hole of the adjacent rigid support member, the operation is stopped to facilitate subsequent maintenance. This avoids the situation where a locking member fails to properly engage, resulting in insufficient support for the collection hose. The positioning detection module facilitates timely detection of problems.

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

[0008] By adopting the above technical solutions, the columnar and perforated structures are more compact than the baffle pattern.

[0009] The present invention is further configured such that: the floating part is provided with a depth mark, the depth mark being used to mark the distance from the rigid support to the end of the collection hose.

[0010] By adopting the above technical solution, the water depth of the sampling hose in the floating part can be determined by the depth marker. Due to the existence of the hose support component, the hose will not drift around, which makes the depth marker meaningful.

[0011] The present invention is further configured such that: the positioning detection module further includes a storage unit, the image acquisition unit and the generation unit are both connected to the storage unit, 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 contains a depth identifier.

[0012] By adopting the above technical solution, the unlocked signal or partially locked signal stores the current image to be tested, which facilitates the replacement of the locking device after the current sampling is completed. The depth markings on the locking device help operators quickly find the corresponding defective locking device that cannot float or cannot float completely.

[0013] The invention is further configured such that: the winding device is equipped with a floating fixing component, and the floating fixing component is provided with a guide hole for the passage of the collection hose, the guide hole being perpendicular to the water surface.

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

[0015] The invention is further configured such that: the floating fixing member is provided with a pushing component that cooperates with the hose support assembly; the pushing component 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 a locking member; when the generating unit generates an unlocked signal, the power member drives the pushing member to move toward the locking member that generated the unlocked signal; the pushing slope abuts against the locking member and drives the locking part of the adjacent rigid support member of the locking part one to cooperate; 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 problem of locking components that generate no locking signal or partial locking signal being unable to move autonomously due to buoyancy is solved by using a power component to drive the pushing component to move. The pushing slope of the pushing component abuts against the locking component, driving the locking component to move towards the locking component of the adjacent rigid support component, thus driving the locking component and the locking space to form a full locking setting.

[0017] The invention is further configured such that: the rigid support is provided with a limiting member for sliding; when the color mark is not covered or partially covered, the locking member restricts the sliding of the limiting member; when the color mark is completely covered, the locking member does not restrict the sliding of the limiting member; after the limiting member slides relative to the rigid support, the limiting member abuts against one side of the locking member to prevent the locking part one from disengaging from the locking part two of the adjacent rigid support; the limiting member is provided with a magnetic suction part one; the pushing member is provided with a magnetic suction part two for attracting the magnetic suction part one; when the pushing slope causes the locking hole to completely cover the color mark of the locking pin, the magnetic suction part two is opposite to the magnetic suction part one, and the pushing member resets to drive the limiting member to move.

[0018] By adopting the above technical solution, for locking components that generate unlocked signals or partial locking signals, which are unable to float actively or can only float partially due to various reasons, the limiting component is used to actively lock them. In order to prevent the locking part one from separating from the locking part two due to jamming or insufficient buoyancy during operation, the locking part one is set apart.

[0019] The present invention is further configured such that: the guide hole is provided with a magnetic suction member three for attracting magnetic suction member one; when magnetic suction member three and magnetic suction member one are in a state of mutual attraction, the limiting member is controlled by the sliding of magnetic suction member three and the limiting member is not abutted against one side of the locking member.

[0020] By adopting the above technical solution, in order to solve the problem that the limiting component cannot be actively reset after being magnetically attracted, which makes it difficult to rewind, the winding device uses magnetic component three to attract magnetic component one when rewinding the collection hose, thereby completing the reset of the limiting component. As a result, the locking component disengages from the locking part two under its own gravity.

[0021] The present invention is further configured such that: an independent collection component is provided at the end of the collection hose, the independent collection component includes a fixed base, a collection seat connected to the fixed base and a sampling bottle, the fixed base is fixedly connected to a rigid support at the end of the collection hose, the collection seat is detachably connected to the sampling bottle, a sampling hole is provided on the collection seat and the sampling hole is connected to the sampling bottle, and a valve plate for opening or closing the sampling hole is provided on the collection seat.

[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 the sampling tube is being sampled, the stability of the rigid support can be used to independently sample at a given depth.

[0023] The present invention is further configured such that: the valve plate is pivotally connected to the acquisition seat; the valve plate is provided with a torsion spring; the torsion spring is used to drive the valve plate to be in a closed state relative to the acquisition hole; the valve plate is connected to a pull rope; the movement of the pull rope can drive the valve plate to be in an open state relative to the acquisition hole; and each rigid support member is provided with a through hole for the pull rope to pass through.

[0024] By adopting the above technical solution, in order to solve the problem of data collection and control, with the support of rigid components, the valve can be opened by manually or electrically pulling the rope. When the valve is opened, under the action of water pressure, the water sample at the location of the independent collection component enters the sampling bottle through the sampling hole. After the rope is released, the valve is reset and the sampling hole is closed again under the action of the torsion spring. When the sampling water pipe is retrieved, water samples from other locations are prevented from entering the sampling bottle. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0032] Example 1:

[0033] A portable water quality sampling system for water storage tanks, first see Figure 1 The system includes a collection hose 1, a winding device 2 for winding the collection hose 1, a hose support assembly 3, and an independent collection assembly 4. The winding device 2 includes a winding base 21, a winding wheel 22, and a winding motor 23. The collection hose 1 is designed as a hose that can be wound around the winding wheel 22. The operation of the winding motor 23 can drive the winding wheel 22 to rotate. The rotation of the winding wheel 22 can play the role of releasing or retracting the hose. The collection hose 1 is connected to a collection water pump.

[0034] See Figure 1 and Figure 2 The hose support component 3 is installed on the collection hose 1. The hose support component 3 is used to drive the collection hose 1 to play a supporting role after entering the water. After entering the water, the collection hose 1 has support and can avoid collision with the side wall of the collection well or other objects, just like a rigid pipe, so as not to cause water turbidity and affect the detection of water at a given depth. It can also prevent the hose from twisting or shaking from side to side due to water flow, which would prevent it from accurately reaching the detection depth, unlike traditional hoses.

[0035] See Figure 1 and Figure 2The hose support assembly 3 includes several rigid support members 31 and several locking members 32. Each rigid support member 31 is fitted with a locking member 32. The rigid support members 31 are evenly spaced on the collection hose 1. Each rigid support member 31 includes a connecting part 311 and a supporting part 312. The connecting part 311 is annularly sleeved on the hose and is fixedly attached by adhesive. In this embodiment, the supporting part 312 is sheet-shaped, but it is not limited to a sheet shape and can also be annular or arc-shaped with the hose as the center. In this embodiment, the supporting part 312 is square sheet-shaped and made of rigid plastic. The supporting part 312 has a locking part 313 that cooperates with the locking member 32. The locking member 32 is slidably disposed on the side of the supporting part 312 away from the connecting part 311. 2 includes an upper floating part 321 and a locking part 322. The upper floating part 321 has a hollow cavity structure without openings. In this embodiment, the locking part 322 has a hole-shaped locking hole. The locking hole formed by the locking part 322 is opened in the upper floating part 321, but the locking hole formed by the locking part 322 is a countersunk hole. The upper floating part 321 has a hollow cavity structure without openings. The locking part 313 has a columnar structure that cooperates with the locking part 322 in this embodiment. The columnar structure of the locking part 322 forms a locking pin. In this embodiment, two cylindrical locking pins are provided, but it is not limited to two pins and can also be one or more. The locking part 32 has two locking holes. The two locking pins are respectively provided to cooperate with the two locking holes. The locking pins are solid structures.

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

[0037] When the winding device 2 is in the unwinding state, the rigid support members 31 of the hose support assembly 3 enter the water in sequence. The floating part 321 after entering the water forms buoyancy in the water, driving the locking member 32 to float. The locking part 322 of the locking member 32 is engaged with the locking part 313 of the adjacent rigid support member 31 above. When the winding device 2 is in the winding state, the rigid support members 31 of the hose support assembly exit the water in sequence. The floating part 321 after exiting the water has no buoyancy in the water, so the floating part descends under its own weight, causing the locking part 322 to disengage from the adjacent locking part 313.

[0038] See Figure 1 and Figure 3A floating fixing member 24 can be pivotally or detachably connected to the winding base 21. The winding device can be placed on the shore or on a supported boat. After the floating fixing member 24 is removed, it can be placed on the water surface. The floating fixing member 24 has a hollow cavity structure or is made of a material that can float on the water surface. A guide post 241 protrudes from the floating fixing member 24. The guide post 241 is partially set underwater. The guide post 241 has a guide hole 242 for the passage of the collection hose 1. The guide hole 242 is opened perpendicular to the water surface. Guide strips 314 protrude from both sides of the rigid support member 31. The guide hole 242 has a guide groove 243 that slides and cooperates with the guide strips 314. The length direction of the guide groove 243 is parallel to the circumferential direction of the center of the guide hole 242. The guide post 241 is set to facilitate the rigid support member 31 to enter the water in a direction perpendicular to the water surface, and to facilitate the locking member 32 to float up and cooperate with the rigid support member 31 above after entering the water.

[0039] In this embodiment, the locking part 322 adopts a locking hole structure, and the locking part 313 adopts a locking pin structure. A color mark 33 is painted on the columnar locking part 313. When the locking part 322 and the locking part 313 of the adjacent rigid member 31 are fully engaged, the locking pin is fully inserted into the locking hole, and the locking hole completely covers the color mark 33 of the locking pin. When the locking part 322 is not engaged with the locking part 313 of the adjacent rigid member 31... During engagement, the locking hole does not cover the color marking 33 of the locking pin. When the locking hole partially engages with the locking pin of the adjacent rigid support 31, the locking hole partially covers the color marking 33 of the locking pin. After entering the water, the locking hole does not cover or only partially covers the color of the locking pin. This may be because the buoyancy of the floating part 321 may be insufficient due to damage or excessive manufacturing weight, preventing the locking part 32 from engaging with the adjacent rigid support 31 facing the water surface.

[0040] The water sampling equipment also includes a positioning detection module 6, which includes an image acquisition unit 61, a comparison unit 62, a generation unit 63, and a storage unit 64.

[0041] Image acquisition unit 61 includes an image acquisition device for acquiring the image to be tested; comparison unit 62 generates matching occlusion information by comparing the length of color mark 33 in the standard acquired image and the image to be tested, and the comparison unit 62 stores the standard acquired image; generation unit 63 generates an unlocked signal, a partially locked signal and a fully locked signal according to the matching occlusion information; both image acquisition unit 61 and generation unit 63 are connected to storage unit 64. When generation unit 63 generates an unlocked signal and a partially locked signal, storage unit 64 stores the current image to be tested according to the unlocked signal or the partially locked signal. The floating part 321 is provided with a depth mark 34, which is used to mark the distance from the rigid support 31 to the end of the acquisition hose 1. The image to be tested contains the depth mark 34. The depth mark 34 can be used to determine the water depth of the acquisition hose 1 by the floating part 321. The winding device 2 stops the hose release operation according to the unlocked signal.

[0042] The floating fixture 24 is provided with a pushing component 5 that cooperates with the hose support assembly 3. The pushing component 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 is an electric push rod, but it is not limited to a linear motor. It can also be a standard component with linear motion such as a cylinder or linear motor. The pushing member 51 is a trapezoidal block with a pushing slope 53 that cooperates with the locking member 32. The power member 52 is covered with a waterproof shell, which is fixedly connected to the floating fixture 24. When the generating unit 63 generates an unlocked signal, the power member 52 drives the pushing member 51 to move toward the locking member 32 that generated the unlocked signal. The pushing slope 53 abuts against the locking member 32 and drives the locking part 2 313 of the adjacent rigid support member 31 of the locking part 1 322 to cooperate. The pushing slope 53 drives the locking hole to completely cover the color mark 33 of the locking pin.

[0043] The rigid support 31 has a sliding hole 54, and a rod-shaped limiting member 55 is slidably disposed within the sliding hole 54. The sliding direction of the limiting member 55 is perpendicular to the sliding direction of the locking member 32. When the locking part 1 322 and the locking part 2 313 are not engaged or partially engaged, that is, when the color mark 33 is not covered or partially covered, the locking member 32 blocks the limiting member 55, preventing the limiting member 55 from extending. When the locking part 1 322 and the locking part 2 313 are fully engaged, the locking pin is in a fully engaged state. When fully engaged in the locking hole state, color marking 33 is completely covered. At this time, locking member 32 does not restrict the movement of limiting member 55. However, when limiting member 55 partially extends out of sliding hole 54, limiting member 55 restricts locking member 32, thus preventing locking part 1 322 from disengaging from adjacent locking part 2 313. This also prevents locking part 322 from disengaging from adjacent locking part 2 313 after being pushed into the water due to damage to floating part 321.

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

[0045] When the winding device 2 is in the winding state, in order to avoid the phenomenon that the locking member 32 cannot disengage from the adjacent rigid member 31 due to the limitation formed by the limiting member 55 on the locking member 32, a magnetic suction member 38 is provided in the guide post 241. The magnetic suction member 1 56 at the end of the limiting member 55 away from the pusher 51 is opposite to the magnetic suction member 38. When the magnetic suction member 38 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, driving the limiting member 55 to reset. When the limiting member 55 retracts into the sliding hole 54, the limiting member 55 does not interfere with the locking member 32, so that the locking member 32 can disengage from the adjacent rigid member 31. After the rigid member 31 moves out of the guide hole 242, it is convenient for the winding drum to wind. In this embodiment, the magnetic member 1, magnetic member 2 and magnetic member 3 are all magnets, but it is not limited to using magnets. Magnets and iron blocks that can be attracted by magnets can also be used.

[0046] An independent sampling component 4 is provided at the end of the sampling hose 1. The independent sampling component 4 includes a fixed base 41, a sampling seat 42 connected to the fixed base 41, and a sampling bottle 43. The fixed base 41 is fixedly connected to the rigid support 31 at the end of the sampling hose 1. The sampling seat 42 and the sampling bottle 43 are detachably connected. In this embodiment, the sampling seat 42 is provided with a threaded countersunk hole, and the sampling bottle 43 is provided with a threaded bottle mouth that mates with the threaded countersunk hole. The sampling seat 42 has a sampling hole 45 communicating with the threaded countersunk hole. The sampling hole 45 is configured to communicate with the sampling bottle 43. A valve plate 44 for opening or closing the sampling hole 45 is pivotally connected to the sampling seat 42. A torsion spring is provided on the pivot shaft. A spring is used to drive the valve plate 44 to be closed relative to the sampling hole. A pull rope is connected to the end of the valve plate 44 away from the pivot. The movement of the pull rope can drive the valve plate 44 to be open relative to the sampling hole. A through hole is provided on the rigid support 31 for the pull rope to pass through. With the support of the rigid support 31, the valve plate 44 can be opened by manually or electrically pulling the pull rope. When the valve plate 44 is open, under the action of water pressure, the water sample at the location of the independent sampling component 4 enters the sampling bottle 43 through the sampling hole 45. After the pull rope is released, the valve plate 44 is reset and the sampling hole 45 is closed again under the action of the torsion spring. When the sampling water pipe is retrieved, water samples from other locations are prevented from entering the sampling bottle 43.

[0047] Example 2:

[0048] The difference between this embodiment and embodiment one is that in this embodiment, the locking part 322 on the locking member 32 is a protruding column, which is a locking pin, and the locking part 313 on the rigid support member 31 is a countersunk hole, which is a locking hole.
