Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection samplers, in particular to a water quality sampler for river channel management. Background Art

[0002] River management can not only reduce the probability of water disasters, but also improve water quality. By adopting means such as pollution interception and reduction, siltation cleaning, etc., the silt in the riverbed can be cleaned up, and the debris on the river surface can be intercepted, which can ensure the fluidity of the river flow and prevent garbage from polluting the river water quality. During the management period, the water quality of the river needs to be tested regularly to grasp the management effect in time, which can prevent the water quality from deteriorating. When testing the water quality, it is necessary to use a sampler to sample the river water and bring the sample back to the laboratory for testing.

[0003] In actual use, most of the existing river management water quality samplers adopt the methods of pumping water and manually filling water for sampling. The pumping method requires throwing the hose at the end of the water pump into the river, and the water pump draws river water as a sample for testing. The manual water filling method requires people to hold a container to draw water at the riverside, and samples can be easily obtained.

[0004] However, both of the above methods have disadvantages: in the pumping method, if the hose is thrown into the river, when the hose is not filled with water, the hose floats on the water surface. As the river water continues to flow into the hose, the hose begins to sink and eventually settles on the river bank. The manual water filling method can only sample the water area near the river bank. Both methods make it difficult to sample river water of different depths. Therefore, the test results are bound to be limited, which significantly reduces the accuracy of water quality testing.

[0005] In view of this, the present application proposes a river management water quality sampler that can sample river water of different water depths and thereby improve the accuracy of water quality detection. Summary of the invention

[0006] The purpose of the utility model is to solve the problem that it is difficult to sample river water of different water depths in the background technology, and to propose a river management water quality sampler that can sample river water of different water depths and thereby improve the accuracy of water quality detection.

[0007] The technical solution of the utility model is as follows: a water quality sampler for river management, including a buoyancy box, a winding roller fixed inside the buoyancy box, a plurality of groups of lifting ropes wound around the winding roller, one end of the lifting rope passes through a circular opening drilled at the bottom plate of the buoyancy box and is fixedly installed with a sampling barrel, the sampling barrel is used to take water and can be used as an anchor component, a side hanging plate fixed on the outer wall of the buoyancy box, a buoyancy barrel is fixedly installed on the side hanging plate, and the hollow enclosed area inside the buoyancy barrel can provide buoyancy for the buoyancy box placed on the water surface.

[0008] Optionally, a water intake port is drilled at the top of the sampling tube, and a conical lead block is provided at the bottom of the sampling tube.

[0009] Optionally, a sealing cover is threadedly mounted at the top opening of the floating barrel, and a curved barrel bottom is provided at the bottom of the floating barrel.

[0010] Optionally, a circular limiting opening is bored on the side hanging plate, the bottom end of the floating bucket passes through the circular limiting opening and extends to the bottom of the side hanging plate, and the sealing cover covers the top of the circular limiting opening.

[0011] Optionally, a positioning bolt is threadedly mounted on the side suspension plate, and the sealing cover is pressed onto the bottom of the nut end of the positioning bolt.

[0012] Optionally, two brackets are fixedly installed inside the pontoon, the winding roller is rotatably installed at a position between the two brackets, a motor is fixedly installed inside the pontoon, and the output shaft of the motor is fixedly connected to one end of the roller shaft of the winding roller.

[0014] Optionally, a rubber sealing gasket is placed in the internal thread groove at the bottom of the sealing cover, and the external thread opening structure at the top of the floating barrel is inserted into the internal thread groove and in close contact with the rubber sealing gasket.

[0030] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example

[0031] like Figure 1-Figure 4 As shown, a water quality sampler for river management proposed by the utility model comprises a buoyancy box 1, two brackets 9 are fixedly installed inside the buoyancy box 1, and a winding roller 10 is rotatably installed on the two brackets 9, and a plurality of groups of suspension ropes 6 are wound around the winding roller 10, one end of the suspension rope 6 passes through a circular opening cut at the bottom plate of the buoyancy box 1 and is fixedly connected to a sampling tube 7, and sampling can be carried out after the sampling tube 7 sinks into the water; and as river water pours into the sampling tube 7, the weight of the sampling tube 7 can be increased, and after a plurality of sampling tubes 7 filled with water dive at the same time, they can play the role of an anchor structure, which can prevent the buoyancy box 1 from generating a drastic change with the water flow. Violent shaking; side hanging plates 3 are fixedly installed on the four outer walls of the pontoon 1 by screws, and a floating barrel 5 with a hollow internal structure is installed on the side hanging plate 3, which can provide sufficient buoyancy for the pontoon 1 to ensure that the pontoon 1 can float stably on the water surface; a motor 8 is fixedly installed inside the pontoon 1 and on one side of the winding roller 10, and the output shaft of the motor 8 is fixedly connected to one end of the roller shaft of the winding roller 10. The winding roller 10 is driven by the motor 8 to rotate, so that the lifting rope 6 can be wound or released, which is convenient for adjusting the diving depth of the sampling tube 7 and can sample river water of different water depths.

[0032] Furthermore, a conical lead block 71 is fixedly installed at the bottom of the sampling tube 7, which can improve the quality of the bottom of the sampling tube 7 and ensure that the sampling tube 7 can be vertically embedded in the water. When the sampling tube 7 is embedded in the water, river water is poured into its internal cavity from the water intake 72 drilled at the top of the sampling tube 7, which makes it convenient to take samples; the bottom of the floating barrel 5 is provided with a curved barrel bottom 53. After the floating box 1 is thrown into the water, the curved barrel bottom 53 can float more stably in the top water surface, effectively reducing the possibility of the floating box 1 tipping over.

[0033] Secondly, a sealing cover 51 is threadedly installed on the top of the float barrel 5, and an internal thread groove is drilled at the bottom of the sealing cover 51. The external thread structure at the top of the float barrel 5 is embedded in the internal thread groove and threadedly connected thereto, ensuring that the sealing cover 51 can be firmly connected to the float barrel 5 as a whole; a rubber sealing gasket 52 is placed in the above-mentioned internal thread groove. When the float barrel 5 is threadedly connected to the sealing cover 51, the top of the float barrel 5 is in close contact with the rubber sealing gasket 52, which can seal the gap at the connection between the float barrel 5 and the sealing cover 51, thereby ensuring the airtightness of the hollow structure inside the float barrel 5 and preventing water from entering the float barrel 5.

[0034] Furthermore, a circular limit opening 32 is bored on the side suspension plate 3, the bottom end of the float barrel 5 passes through the circular limit opening 32 and extends to the bottom of the side suspension plate 3, and the sealing cover 51 covers the area above the circular limit opening 32, the positioning bolt 31 is threadedly installed on the top of the side suspension plate 3, and the sealing cover 51 is ensured to be pressed between the nut end of the positioning bolt 31 and the side suspension plate 3, thereby positioning the sealing cover 51, ensuring that the float barrel 5 can be firmly installed on the side suspension plate 3, and the convenience of disassembly and assembly of the float barrel 5 can be improved.

[0035] It is worth mentioning that a box cover 2 is snap-fitted and installed at the top opening of the buoyancy box 1, and the box cover 2 can be fixed by screws to seal the top of the buoyancy box 1. When the buoyancy box 1 is thrown into the water, the splashing water can be prevented from entering the interior of the buoyancy box 1 from the top opening, thereby preventing the motor 8 from contacting the water, thereby playing a protective role; a hook 4 is fixedly installed at one end of the buoyancy box 1, and a towing rope is tied to the hook 4. When the buoyancy box 1 needs to be retrieved from the surface of the river, the towing rope can be pulled on the river bank to pull the buoyancy box 1 to the river bank, which is convenient for its recovery.

[0036] In this embodiment, firstly tie the traction rope to the hook 4, hold the traction rope away from the end of the pontoon 1, and throw the pontoon 1 into the water surface of the river. At this time, the curved bottom 53 of the bottom of the float barrel 5 first contacts the water surface. With the help of the curved bottom 53, the bottom of the float barrel 5 can be more stably sunk into the water, reducing the probability of the float 1 tipping over. Since the interior of the float barrel 5 is a hollow and closed structure, it can provide sufficient buoyancy for the float 1 to ensure that the float 1 can stably float on the water surface; the winding roller 10 is driven by the motor 8 to rotate, Then the suspension rope 6 is paid out so that the sampling tube 7 can move downward. The conical lead block 71 can ensure that the sampling tube 7 is submerged in the water in a vertical state. When the sampling tube 7 is not filled with water, the weight of the conical lead block 71 can ensure that the center of gravity of the sampling tube 7 is downward, preventing the sampling tube 7 from being thrust by the water flow and becoming horizontal when in contact with the water surface, thereby ensuring that the sampling tube 7 can stably submerge into the river water. At this time, the river water is injected into the internal cavity of the sampling tube 7 from the water intake 72, making it convenient to sample the river water.

[0037] A circuit board for controlling the motor 8 is installed inside the pontoon 1, and a wireless transceiver is installed on the circuit board. The staff can control the motor 8 to rotate forward and reverse on the river bank, which is convenient for adjusting the length of the suspension rope 6 extending to the outside of the pontoon 1, and then adjust the diving depth of the sampling tube 7, so as to sample river water at different depths. Compared with the existing sampling methods (water pumping sampling and handheld containers for holding water), the sampler in the present application can sample river water at different depths in the river, which solves the problem that the existing samplers can only sample the area near the river bank or the upper water flow of the river, avoids the sampling range being limited and resulting in the detection results being not comprehensive, and effectively improves the accuracy of water quality detection.

[0038] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
