Description

Technical Field

[0001] The invention relates to the technical field of sampling tools, in particular to a sampling device for garden landscape water management. Background Art

[0002] As an important part of the urban ecological environment, the water quality of landscape water directly affects the quality of life of urban residents and the overall beauty of the city. However, due to industrial wastewater discharge, domestic sewage infiltration, pollutants carried by rainwater runoff, and the accumulation of nutrients in the water body, landscape water bodies often face problems such as eutrophication and increased pollution, which not only destroys the ecological balance of the water body, but also affects people's perception and health. For this reason, it is often necessary to sample and test lakes and other waters in the garden to provide the prerequisite for subsequent symptomatic treatment.

[0003] According to the search, the Chinese patent document, announcement number: CN116465689B, discloses a sampling device for river sewage treatment. Through the filter shells on both sides, the sewage entering the collection sample shell is filtered to remove waste residues. After the collection sample shell is taken out, the hollow collection box shell can be put into the water, and the inner cavity of the collection box shell is pressurized through the modified buoy above, so that the sewage without large impurities in the collection box shell is reversely ejected from the inner cavity of the filter shell, and then the impurities blocked in the outer opening of the filter shell are ejected, thereby playing a dredging function, which conveniently solves the problem of blockage when the filter shell is working continuously.

[0004] However, the above sampling device still has the following defects during actual use: once the sampling tube enters the water body during the sampling process, water will enter, making it impossible to sample at a quantitative depth, which makes the sampling one-sided and not comprehensive enough.

[0018] Compared with the prior art, the present invention provides a sampling device for landscape water management, which has the following beneficial effects:

[0019] 1. The present invention is provided with structures such as a depth-fixing rope, a rubber ball, a clamping block, and a metal ring engraved with length numbers. The outer surface of the metal ring is engraved with length unit numbers. By loosening the knob, a suitable metal ring is selected according to the numbers on different metal rings and the sampling depth requirements, the clamping block is moved to make the selected metal ring in the through hole of the clamping block, and then the knob is tightened to connect the clamping block with the metal ring, thereby limiting the position of the rubber ball.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See also Figure 1-Figure 6 A sampling device for landscape water management comprises a sampling tube 1, the outer surface of the sampling tube 1 is fixedly connected to an ear block 2, the inside of the ear block 2 is connected to a rubber band 3, one end of the rubber band 3 is connected to an ear block 4, the bottom of the ear block 4 is fixedly connected to a bottom plate 5, the top center of the bottom plate 5 is fixedly connected to a vertical rod 6, the bottom center of the bottom plate 5 is connected to a piston 7 through a screw, the outer surface of the sampling tube 1 is fixedly connected to a metal ring 8 near the top, the top of the metal ring 8 is fixedly connected to three inclined slot plates 9, one end of the three inclined slot plates 9 is fixedly connected to a ferrule 10, a limiting opening 11 is provided on the outer surface of the vertical rod 6, and the inside of one of the inclined slot plates 9 is fixedly connected to a piston 7. A connecting plate 12 is fixedly connected, and the connecting plate 12 is internally slidably connected to a sleeve rod 13, one end of the sleeve rod 13 is fixedly connected to a wedge block 14, the outer surface of the sleeve rod 13 is sleeved with a compression spring 15, and the other end of the sleeve rod 13 is fixedly connected to a limit block 16, the outer surface of the limit block 16 is fixedly connected to a depth-fixing rope 17, the insides of the three inclined slot plates 9 are rotatably connected to a pulley No. 18, one of the inclined slot plates 9 is internally rotatably connected to a pulley No. 2 19, and a circular hole 20 is penetrated through the top surface of the inclined slot plate 9, the outer surface of the depth-fixing rope 17 is movably connected to a block 21, the outer surface of the block 21 is fixedly connected to a rubber ball 22, and the bottom surface of the sampling tube 1 is threadedly connected to a hose 23.

[0032] Furthermore, the inside of the ferrule 10 is slidably connected to the vertical rod 6, the outer surface of the piston 7 is in contact with the sampling tube 1, and three rubber bands 3 are arranged circumferentially around the axis of the vertical rod 6. The advantage is that before sampling the scenic waters in the garden, the vertical rod 6 is pressed to drive the piston 7 to move downward until the piston 7 contacts the inner bottom surface of the sampling tube 1, so that the ear block 2 4 can drive one end of the rubber band 3 downward, so that the rubber band 3 can be stretched to store force.

[0033] Furthermore, the wedge block 14 is clamped in the limiting opening 11, one end of the compression spring 15 abuts against the wedge block 14, and the other end of the compression spring 15 abuts against the connecting plate 12. The advantage is that since the compression spring 15 has a resistance force on the wedge block 14, the wedge block 14 can be kept in contact with the outer surface of the vertical rod 6, and the position of the wedge block 14 can be limited by setting the limiting block 16 and the sleeve rod 13, so that when the vertical rod 6 drives the piston 7 to descend to the bottom of the sampling tube 1, the wedge block 14 is just embedded in the limiting opening 11. At this time, before sampling the water area, since the limiting wedge block 14 is clamped in the limiting opening 11, the piston 7 can be prevented from rising due to the elastic force of the rubber band 3.

[0034] Furthermore, a hanging ring 24 is welded to the top of the vertical rod 6, and a cotton rope 25 is connected to the hanging ring 24. The advantage is that by passing one end of the cotton rope 25 through the hanging ring 24 and then tying the cotton rope 25, the vertical rod 6 can be connected to the sampling tube 1 and other components by setting the cotton rope 25. When the sampling tube 1 is put into the water area in the garden, the sampling tube 1 and the water sample inside it can be extracted by pulling the cotton rope 25 after sampling.

[0035] Furthermore, a through hole is formed through the upper surface of the block 21, and the through hole and the upper and lower surfaces of the block 21 are chamfered. The outer surface of the block 21 is threadedly connected to the knob 26, and the depth-fixing rope 17 passes through the circular hole 20, and the depth-fixing rope 17 is in sliding contact with the second pulley 19, and the two ends of the rotating shaft of the second pulley 19 are rotatably connected to the U-shaped frame 30. The advantage is that when the sampling tube 1 is placed in the water area in the garden, since the depth-fixing rope 17 and the rubber ball 22 are provided, and the block 21 is located at a certain section of the depth-fixing rope 17, when the sampling tube 1 is submerged in the water area, as the sampling tube 1 descends, one end of the depth-fixing rope 17 will be driven to descend, and the rubber ball 22 floats on the water surface. When the sampling tube 1 descends to a specified depth, the depth-fixing rope 17 will be straightened. At this time, under the buoyancy of the rubber ball 22 and the gravity of the sampling tube 1, The depth-fixing rope 17 is forced to pull the limit block 16, the limit block 16 pulls the sleeve rod 13, and the sleeve rod 13 pulls the wedge block 14 to make it withdrawn from the limit opening 11, so that the vertical rod 6 loses its limit. At this time, the three rubber bands 3 contract and drive the three ear blocks 2 4 to rise, the three ear blocks 2 4 drive the bottom film 5, and the bottom film 5 drives the vertical rod 6 to rise, so that the piston 7 rises. Since the outer surface of the piston 7 is close to the inner wall of the sampling tube 1, the water sample can be drawn into the interior of the sampling tube 1 through the hose 23.

[0036] Furthermore, the inclined slot plate 9 is welded to the top of the metal ring 8, and three inclined slot plates 9 are arranged around the circumference of the ring 10, and the inner ends of the three inclined slot plates 9 and away from the ring 10 are rotatably connected to the first pulley 18. The advantage is that by arranging three first pulleys 18 to contact the outer surface of the rubber band 3, the rubber band 3 can be turned with the assistance of the first pulley 18 during the stretching or contraction period.

[0037] Furthermore, a plurality of metal rings 27 arranged at equal intervals are fixedly connected to the outer surface of the depth-fixing rope 17, and length numbers are engraved on the outer surface of the metal ring 27. The advantage is that the length unit numbers are engraved on the outer surface of the metal ring 27, and the screw rod is withdrawn from the through hole of the block 21 by loosening the knob 26, and then a suitable metal ring 27 is selected according to the numbers engraved on different metal rings 27 and the sampling depth requirements, and then the block 21 is moved to drive the rubber ball 22 to move, so that the selected metal ring 27 is in the through hole of the block 21, and then the knob 26 is tightened to make the screw rod close to the metal ring 27, so that the block 21 can be connected with the metal ring 27, so that the position of the rubber ball 22 is limited, and then the sampling depth can be limited.

[0038] Furthermore, the center of the bottom surface of the sampling tube 1 is fixedly connected to a spiral tube, and the outer surface of the spiral tube is threadedly connected to a metal cone 28. The advantage is that the sampling tube 1 is set to be a transparent plastic material, and because its bottom is a plane, it usually has a certain buoyancy when thrown into the water, and it is not easy for the sampling tube 1 to go deep into the water. By connecting the metal cone 28 to the center of the bottom of the sampling tube 1, the weight of the bottom of the sampling tube 1 is increased, thereby overcoming the buoyancy of the sampling tube 1 on the water surface, and facilitating the sampling tube 1 to go deep into the water area.

[0039] Furthermore, a water inlet is provided at the bottom of the sampling barrel 1, and the inner thread of the water inlet is connected to the hose 23, and the outer surface of the sampling barrel 1 is fixedly connected to the buckle 29, and the hose 23 is clamped in the buckle 29. The advantage is that the hose 23 can be fixed to the outer surface of the sampling barrel 1 by setting the buckle 29, so that the port position of the hose 23 can be higher than the port position of the sampling barrel 1, so that when the piston 7 rises and the interior of the sampling barrel 1 sucks the water sample, during the period of pulling the cotton rope 25 to extract the sampling barrel 1, because the flow of the liquid requires a certain pressure difference or power drive, and the port position of the hose 23 is higher than the port position of the sampling barrel 1, the water inside the sampling barrel 1 will not flow out from the hose 23, so that the water sample can be retained inside the sampling barrel 1.

[0040] Furthermore, the metal ring 8 is directly connected to the sampling tube 1 by rivets, and milliliter scale lines are engraved on the outer surface of the sampling tube 1. The advantage is that when the sampling tube 1 is filled with water sample and pulled out into the hands of the staff, the hose 23 can be released by breaking the buckle 29, and the water inside the sampling tube 1 can be released after the hose 23 is vertically placed. The hose 23 can be inserted into the collection bottle to conveniently collect the water sample, and the milliliter scale lines on the outer surface of the sampling tube 1 can be observed to conveniently know how much water sample is collected.

[0041] When in use, firstly, the piston 7 is driven down by pressing the vertical rod 6 until the piston 7 is fitted to the inner bottom surface of the sampling tube 1. At this time, the wedge block 14 is inserted into the limit opening 11 to limit the vertical rod 6. Then, a suitable metal ring 27 is selected according to the numbers engraved on different metal rings 27 and the sampling depth requirements. Then, the block 21 is moved to drive the rubber ball 22 to move, so that the selected metal ring 27 is in the through hole of the block 21. Then, the knob 26 is tightened to make its screw close to the metal ring 27, so that the block 21 can be connected with the metal ring 27. In this way, the position of the rubber ball 22 is limited, and then the sampling depth is limited. Then, hold one end of the cotton rope 25 and put the sampling tube 1 into the water in the garden. Under the gravity of the metal cone 28, it is convenient for the sampling tube 1 to penetrate deeply. When the sampling tube 1 reaches the set sampling depth, the buoyancy of the rubber ball 22 and the gravity of the sampling tube 1 will force the depth-fixing rope 17 to pull the limit block 16, the limit block 16 pulls the sleeve rod 13, the sleeve rod 13 pulls the wedge block 14 to make it withdrawn from the limit port 11, so that the vertical rod 6 loses its limit, and at this time the three rubber bands 3 contract and drive the three ear blocks 24 to rise, the three ear blocks 24 drive the bottom film 5, the bottom film 5 drives the vertical rod 6 to rise, so that the piston 7 rises, and since the outer surface of the piston 7 is close to the inner wall of the sampling tube 1, the water sample can be drawn into the interior of the sampling tube 1 through the hose 23; then the cotton rope 25 is pulled to lift the sampling tube 1 out of the water, and then the buckle 29 is broken to release the hose 23, and the hose 23 is inserted into the collection bottle to collect the water sample.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
