Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sewage sampling, and particularly relates to a sewage treatment sample detection auxiliary device based on water body surveying and mapping services. BACKGROUND

[0002] With the acceleration of urbanization and the development of industrialization, water resource shortage and water pollution problems are becoming increasingly serious. Sewage treatment has become a key measure to protect water resources and improve water environmental quality. However, sewage treatment faces many challenges, such as complex pollution sources, difficult treatment, limited monitoring means, etc. Therefore, advanced technical means need to be used to improve the efficiency and accuracy of sewage treatment. The resource evaluation system considers the quantity, quality, distribution and development and utilization status of water resources when evaluating water resources. These information is crucial for developing sewage treatment strategies, because sewage treatment needs to be planned and implemented based on the actual situation of water resources. Water body surveying and mapping services use advanced surveying and mapping technology and equipment to accurately measure and record water bodies, providing scientific basis for sewage treatment. Through water body surveying and mapping, the location, range and discharge of pollution sources can be accurately determined, providing basis for developing targeted treatment measures. Water body surveying and mapping services can provide high-precision water quality data, including dissolved oxygen content, ammonia nitrogen concentration and other key indicators. These data are of great significance for evaluating water quality and developing water resource protection strategies.

[0003] In the process of sewage treatment, sampling of water quality is a crucial step. Through analysis of water samples, the types, concentrations and distribution of pollutants can be understood, thereby providing important basis for developing scientific and reasonable treatment schemes.

DETAILED DESCRIPTION

[0039] In order to make the above-mentioned objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0040] Embodiment 1, refer to Figures 1-12 , for the first embodiment of the present application, a kind of based on water body surveying and mapping service's sewage treatment sample detection auxiliary device, including sampling barrel 1, fixedly connected in the bottom of sampling barrel 1's counterweight 11, top sampling port 12 being opened in the top of sampling barrel 1, bottom sampling port 13 being opened in the bottom end of sampling barrel 1, multiple fixed ropes 14 being fixedly connected on sampling barrel 1 in the form of annular array distribution, and pull rope 15 being fixedly connected in the top of fixed rope 14, further including sampling unit installed on sampling barrel 1;Sampling unit includes sampling component installed on sampling barrel 1, clamping component installed in sampling barrel 1, and pushing-away component installed on sampling component, sampling component includes buoyancy assembly 2 installed in sampling barrel 1, rotating sealing assembly 3 installed in the bottom of buoyancy assembly 2, and horizontal moving sealing assembly 4 installed in the top of buoyancy assembly 2;Sampling component is used to open and close top sampling port 12 and bottom sampling port 13, clamping component is used to clamp bottom sampling port 13, and pushing-away component is used to open top sampling port 12;Buoyancy assembly 2 includes L-shaped plate 21 fixedly connected in the bottom of sampling barrel 1, stand 22 fixedly connected in one side of L-shaped plate 21, first floating ball 23 limitingly and slidably connected in the outer side of stand 22, and first floating ball 23 is slidably connected with L-shaped plate 21.

[0041] Specifically, by loosening or winding the pull rope 15, putting or lifting the sampling bucket 1 into the water, through the multiple annular array distribution of the fixed rope 14, the sampling bucket 1 can be vertically lifted or lowered, so that the obtained water sample is more accurate, through the counterweight 11, the sampling bucket 1 can overcome the buoyancy of the water and move downward to the specified depth for sampling, through the top sampling port 12 and the bottom sampling port 13, the sampling bucket 1 is in an open state at the top and bottom during sampling, so that the sampling bucket 1 is formed in an up-down through manner, so that the sewage can quickly enter the sampling bucket 1, without the need for a long waiting time, improving the efficiency of sampling, and also improving the accuracy of sampling. When the sampling bucket 1 is lifted, the top sampling port 12 and the bottom sampling port 13 are closed by the sampling component, so that sewage no longer enters the sampling bucket 1, and water in the sampling bucket 1 cannot flow out. After sampling is completed, the sampling bucket 1 is inverted, the top sampling port 12 is pushed open by the pushing component, so that the sample water can flow out. During the flowing out of the sample water, the bottom sampling port 13 will immediately open. At this time, the sampling bucket 1 is in a through state again, so that the water in the sampling bucket 1 can be quickly discharged for collection. Not only does it simplify the operation steps, but also improves the efficiency of water collection. Through the L-shaped plate 21, the stand column 22 is fixedly installed at the bottom of the sampling bucket 1. When water enters the sampling bucket 1, the first floating ball 23 is subjected to the action of the buoyancy and slides upward on the stand column 22 to open the bottom sampling port 13. When the first floating ball 23 moves to the top of the sampling bucket 1, the top sampling port 12 is sealed, and at the same time, the bottom sampling port 13 is closed, so that the sampling bucket 1 forms a sealed structure again.

[0042] Referring to Figure 5 , the rotating sealing assembly 3 comprises two connection shafts 31 symmetrically distributed and rotatingly connected inside the bottom sampling port 13, a rotating sealing plate 32 fixedly connected between the two connection shafts 31, two gears 33 fixedly connected outside the two connection shafts 31, two racks 34 symmetrically distributed and slidingly connected in the sampling bucket 1, the two racks 34 being meshingly connected with the two gears 33 respectively, a first vertical rod 35 and a second vertical rod 36 fixedly connected at the top of the two racks 34 respectively, a first horizontal rod 37 and a second horizontal rod 38 fixedly connected on both sides of the first floating ball 23 respectively, the first vertical rod 35 and the second vertical rod 36 being slidingly connected with the first horizontal rod 37 and the second horizontal rod 38 respectively, and a floating plate 39 fixedly connected at the top of the second vertical rod 36.

[0043] Specifically, when the first floating ball 23 slides upward on the stand 22, the first crossbar 37 and the second crossbar 38 slide outside the first vertical rod 35 and the second vertical rod 36. Since the first vertical rod 35 is shorter than the second vertical rod 36, when the first crossbar 37 slides to the top of the first vertical rod 35, the second crossbar 38 slides to the bottom of the second vertical rod 36. The first crossbar 37 drives the first vertical rod 35 to move upward, and the second crossbar 38 continues to slide on the second vertical rod 36, thereby driving the rack 34 at the bottom of the first vertical rod 35 to move upward, so that the gear 33 engaged with the rack 34 rotates, drives the connecting shaft 31 to rotate, and drives the rotating sealing plate 32 to rotate, thereby opening the bottom sampling port 13 and allowing sewage to enter the sampling barrel 1. The continuous entry of water into the sampling barrel 1 causes the first floating ball 23 to continuously slide upward on the stand 22. When the second crossbar 38 moves to the top of the second vertical rod 36, it drives the second vertical rod 36 to move upward, thereby driving the rack 34 at the bottom to move upward. Since the two racks 34 are centrally symmetrically distributed, the gear 33 engaged with the racks 34 rotates, drives the connecting shaft 31 to rotate in the opposite direction of the previously rotated connecting shaft 31, drives the rotating sealing plate 32 to rotate in the opposite direction, and closes the bottom sampling port 13, so that the water in the sampling barrel 1 no longer flows out.

[0044] With reference to Figure 6 , the horizontal movement sealing assembly 4 comprises a movable groove 41 opened at the top of the sampling barrel 1, a horizontal movement sealing plate 42 slidably connected in the top sampling port 12, the horizontal movement sealing plate 42 being slidably connected with the movable groove 41, a circular groove opened in the movable groove 41, a first spring 43 fixedly connected between the horizontal movement sealing plate 42 and the inner wall of the circular groove, two symmetrically distributed extrusion blocks 44 fixedly connected in the movable groove 41, a first connecting rope 45 fixedly connected to the horizontal movement sealing plate 42, the first connecting rope 45 being slidably connected between the two extrusion blocks 44, a rubber ball 46 fixedly connected to the first connecting rope 45, a first inclined surface 47 opened in the extrusion block 44, a second floating ball 48 slidably connected at the top of the sampling barrel 1, and an end of the first connecting rope 45 away from the horizontal movement sealing plate 42 penetrating through the sampling barrel 1 and being fixedly connected with the second floating ball 48.

[0045] Specifically, the sampling bucket 1 continuously sinks into the sewage, the buoyancy of the second floating ball 48 continuously increases, the second floating ball 48 continuously pulls the first connecting rope 45, and then pulls the rubber ball 46. Since the rubber ball 46 is located on one side of the two extrusion blocks 44, the rubber ball 46 is not easily pulled under the action of the two extrusion blocks 44. When the buoyancy of the second floating ball 48 is greater than the resistance of the two extrusion blocks 44 to the rubber ball 46, the rubber ball 46 can pass between the two extrusion blocks 44, pull the transverse sealing plate 42, and stretch the first spring 43. The elastic force of the first spring 43 is smaller than the buoyancy of the second floating ball 48, so the first spring 43 is easily stretched, the transverse sealing plate 42 moves to one side of the movable groove 41, and the top sampling port 12 is completely opened. At this time, the sampling bucket 1 sinks to a specified depth, and then the water at the specified depth can be sampled. After sampling is completed, the sampling bucket 1 is lifted upwards, the buoyancy of the second floating ball 48 gradually decreases, the first spring 43 resets, the transverse sealing plate 42 slides to the side of the top sampling port 12, the first connecting rope 45 drives the rubber ball 46 to move, and the rubber ball 46 slides off the two extrusion blocks 44 under the action of the first inclined surface 47. That is, the extrusion blocks 44 do not block the rubber ball 46 again, so that the transverse sealing plate 42 is difficult to reset. The top sampling port 12 is sealed by the reset of the transverse sealing plate 42, so that the sewage outside the sampling bucket 1 no longer enters the sampling bucket 1.

[0046] Embodiment 2, refer to Figures 7-9 As a second embodiment of the present application, the difference between this embodiment and the first embodiment is that the clamping component includes a pushing assembly 5 installed at the top of the sampling bucket 1 and a clamping assembly 6 installed at the bottom of the sampling bucket 1. The pushing assembly 5 includes a fixed box 51 fixedly connected to the top of the sampling bucket 1, a pushing rod 52 slidingly connected to the bottom of the fixed box 51, a moving rod 53 limitingly and slidingly connected to one side of the fixed box 51, an inclined surface opened at one end of the moving rod 53, the pushing rod 52 being limitingly and slidingly connected to the inclined surface, two symmetrical guide grooves opened on the moving rod 53, two symmetrical guide blocks fixedly connected to the fixed box 51, a second spring 54 fixedly connected between the guide blocks and the inner wall of the guide groove, a second connecting rope 55 fixedly connected to the other end of the moving rod 53, and a roller 56 fixedly installed on the inner wall of the sampling bucket 1. The second connecting rope 55 passes around the roller 56.

[0047] Specifically, by pushing the assembly 5, the clamping assembly 6 clamps and limits the rotating sealing plate 32, when the first floating ball 23 moves to the top of the sampling barrel 1, the push rod 52 is extruded to move upwards, so that the push rod 52 slides on the inclined surface, so that the moving rod 53 moves outward of the fixed box 51, so that the guide block slides in the guide groove, extruding the second spring 54, so that the second connecting rope 55 moves downwards, under the action of the roller 56, so that the second connecting rope 55 moves along a certain trajectory, so that the clamping assembly 6 limits the rotating sealing plate 32, and then when the sampling barrel 1 is lifted, the bottom sampling port 13 will not be opened, so that the sampling barrel 1 is always in a sealed state.

[0048] With reference to Figure 9 The clamping assembly 6 comprises a sliding groove formed in the bottom of the sampling barrel 1, a sliding block 61 slidably connected in the sliding groove, a second connecting rope 55 fixedly connected with the sliding block 61, a plug rod 62 fixedly connected with the sliding block 61, a plug groove 63 formed in the rotating sealing plate 32, the plug rod 62 being inserted into the plug groove 63, and a third spring 64 fixedly connected between the sliding block 61 and the inner wall of the sliding groove.

[0049] Specifically, when the second connecting rope 55 moves downwards, the third spring 64 is compressed, and the third spring 64 resets, so that the sliding block 61 moves to one side of the rotating sealing plate 32 in the sliding groove, drives the plug rod 62 to move, so that the plug rod 62 is inserted into the plug groove 63, and the rotating sealing plate 32 is limited. The rest of the structure is the same as that of example 1.

[0050] Example 3, with reference to Figures 10-12 This is the third embodiment of the present application, which is different from the second embodiment: the pushing open assembly 7 is installed on the buoyancy assembly 2, the limiting assembly 8 is installed on the buoyancy assembly 2, and the trigger assembly 9 is installed on the pushing open assembly 7; the pushing open assembly 7 comprises a movable cavity 71 formed in the top of the stand column 22, a fixed block 72 limitingly and slidably connected in the movable cavity 71, a pushing open rod 73 fixedly connected at the top of the fixed block 72, the pushing open rod 73 being connected with the top of the movable cavity 71, a first wedge-shaped block 74 fixedly connected at the top of the pushing open rod 73, a second inclined surface 75 formed in the horizontal sealing plate 42, and the first wedge-shaped block 74 being slidably connected with the second inclined surface 75.

[0051] Specifically, when the sampling barrel 1 is full of sample, the sampling barrel 1 is inverted, under the action of gravity, the fixed block 72 slides downward in the movable cavity 71, drives the push-off rod 73 to move downward, drives the first wedge-shaped block 74 to move downward, so that the first wedge-shaped block 74 slides on the second inclined surface 75, under the action of the second inclined surface 75, the transverse sealing plate 42 is pushed into the movable groove 41, so that the top sampling port 12 is opened, so that the sample in the sampling barrel 1 can flow out, due to the inversion of the sampling barrel 1, under the action of the buoyancy of water, the first floating ball 23 moves upward on the stand column 22, so that the first floating ball 23 no longer extrudes the push rod 52, the second spring 54 is reset, so that the moving rod 53 moves into the fixed box 51, pulls the second connecting rope 55, so that the second connecting rope 55 moves upward, pulls the sliding block 61, so that the third spring 64 is extruded, so that the plug rod 62 is separated from the inner side of the plug groove 63, which will no longer limit the rotation of the sealing plate 32, under the action of the buoyancy of water, the floating plate 39 will move upward, drive the second vertical rod 36 to move upward, drive the rack 34 to move upward, drive the gear 33 to rotate, drive the connecting shaft 31 to rotate, drive the rotating sealing plate 32 to rotate, so that the bottom sampling port 13 is opened, so that the sampling barrel 1 is connected through, so that the sample in the sampling barrel 1 is more easily poured out.

[0052] With reference to Figure 11 , the limiting assembly 8 comprises a through hole 81 arranged on the stand column 22 and communicated with the movable cavity 71, two fixed shafts arranged in the through hole 81 and symmetrically distributed, a limiting plate 82 arranged between the two fixed shafts, a torsion spring arranged between the limiting plate 82 and the through hole 81, and the torsion spring is sleeved on the fixed shaft.

[0053] Specifically, through the trigger assembly 9, the limiting plate 82 rotates in the through hole 81, drives the fixed shaft to rotate, so that the torsion spring is twisted and deformed, so that the limiting plate 82 rotates out of the through hole 81, and then limits the first floating ball 23, so that when the water in the sampling barrel 1 is poured out, the first floating ball 23 will not block the top sampling port 12, so that the water in the sampling barrel 1 can be drained.

[0054] With reference to Figure 12 , the trigger assembly 9 comprises an empty slot 91 opened in the fixed block 72, a trigger block 92 slidingly connected in the empty slot 91, a third inclined surface opened in the trigger block 92, and a trigger spring 93 fixedly connected between the inner wall of the empty slot 91 and the trigger block 92.

[0055] Specifically, when the sampling bucket 1 is inverted, the fixed block 72 moves downward in the movable cavity 71, and the trigger block 92 is initially located in the empty slot 91 under the action of the movable cavity 71, and the trigger spring 93 is compressed, when the trigger block 92 moves to the through hole 81, the trigger spring 93 is not forced to reset, so that the trigger block 92 moves to the outside of the empty slot 91 and pushes the limiting plate 82, when the sampling bucket 1 recovers to the upright state, the fixed block 72 moves reversely in the movable cavity 71, under the action of the third inclined surface and the movable cavity 71, the trigger block 92 reenters the empty slot 91, and the torsional spring restores to the original state, so that the limiting plate 82 rotates into the through hole 81.

[0056] With reference to Figure 2 And Figure 3 Further comprising a sealing sleeve 10 arranged at the top of the sampling bucket 1, and the sealing sleeve 10 has a circular truncated cone structure.

[0057] Specifically, when the first floating ball 23 moves upward in the sampling bucket 1, the top of the first floating ball 23 will contact the sealing sleeve 10, and under the joint action of the sealing sleeve 10 and the first floating ball 23, the top sampling port 12 is sealed, and the sealing sleeve 10 has a circular truncated cone structure, so that the first floating ball 23 is more likely to seal the sealing sleeve 10. The remaining structure is the same as that of the embodiment 2.

[0058] In combination with the embodiments 1-3, the working principle of the present application is as follows: in use, under the action of the pull rope 15, the sampling bucket 1 is placed in sewage, and through the fixing rope 14, the sampling bucket 1 is always vertically downward during sampling, the second floating ball 48 is subjected to the action of the buoyancy, pulls the first connecting rope 45, extrudes the first spring 43, pulls the transverse sealing plate 42 to move into the movable slot 41, so that the top sampling port 12 is opened, so that the sewage enters the sampling bucket 1, the first floating ball 23 is subjected to the action of the buoyancy and moves upward on the stand 22, drives the first horizontal rod 37 to move upward, drives the first vertical rod 35 to move upward, drives the rack 34 to move upward, drives the gear 33 to rotate, drives the connecting shaft 31 to rotate, drives the rotating sealing plate 32 to rotate, and the bottom sampling port 13 is also opened, so that the sampling bucket 1 is connected from top to bottom, so that the sewage quickly enters the sampling bucket 1, when the first floating ball 23 moves to the bottom of the sealing sleeve 10, the top sampling port 12 is sealed, the floating plate 39 is subjected to the buoyancy of water, drives the second vertical rod 36 to move upward, under the cooperation of the rack 34 and the gear 33, the rotating sealing plate 32 is also rotated, and the rotating direction is opposite to that before, and the bottom sampling port 13 is also closed.

[0059] The first floating ball 23 extrudes the push rod 52, so that the moving rod 53 moves to the outside of the fixed box 51, extrudes the second spring 54, so that the second connecting rope 55 moves downward, under the action of the third spring 64, so that the sliding block 61 moves to one side of the rotating sealing plate 32 inside the sliding groove, drives the insertion rod 62 to move into the insertion groove 63, limits the rotating sealing plate 32, so that the rotating sealing plate 32 cannot rotate, so that the bottom sampling port 13 cannot be opened, pulls the pull rope 15, the buoyancy of water changes, the buoyancy of the second floating ball 48 decreases, the first spring 43 resets, so that the transverse sealing plate 42 moves into the top sampling port 12, seals the top sampling port 12, lifts the pull rope 15, and moves the sampling bucket 1 out of the water surface, and completes sampling.

[0060] When collecting the sample, the sampling bucket 1 is inverted, the first floating ball 23 is moved upward by the buoyancy, no longer extrudes the push rod 52, no longer seals the sealing sleeve 10, the second spring 54 resets, so that the moving rod 53 moves into the fixed box 51, pulls the second connecting rope 55, so that the sliding block 61 moves away from the rotating sealing plate 32 inside the sliding groove, so that the insertion rod 62 moves out of the insertion groove 63, no longer limits the rotating sealing plate 32, the fixed block 72 slides in the movable cavity 71, drives the push rod 73 and the first wedge block 74 to move, under the action of the second inclined surface 75, pushes away the transverse sealing plate 42, so that the top sampling port 12 is opened, so that the water in the sampling bucket 1 can be discharged, and the floating plate 39 is moved upward under the action of the buoyancy, drives the second vertical rod 36 to move upward, under the action of the rack 34 and the gear 33, drives the rotating sealing plate 32 to rotate, so that the bottom sampling port 13 is also opened, so that the sampling bucket 1 is formed again to be through from top to bottom, so that the water in the sampling bucket 1 can be quickly discharged.
