Description
Technical Field
[0001] The utility model relates to the technical field of water samplers, in particular to a novel floating rod structure of a floating rod bottom - sediment water sampler. Background Art
[0002] The rod bottom - sediment water sampler is mainly used for collecting surface water samples. Its bottom - sediment design has two purposes:
[0003] One is deep - depth collection. The bottom - sediment design enables the water sampler to reach near the bottom of the water body, so as to collect water samples from deeper layers with less external interference. Such water samples can often better represent the overall condition of the water body, especially for those water bodies with water quality differences in the vertical direction.
[0004] The other is to avoid surface pollution. The water body near the water surface is easily affected by various factors such as wind, rain, floating objects, and ship activities, resulting in large fluctuations in water quality. Bottom - sediment water sampling can effectively avoid these surface pollutions and ensure that the collected water samples are purer and more representative.
[0005] The floating rod bottom - sediment water sampler generally includes a floating rod, a water sampling tank, a fixed anchor, and a floating buoy; the water tank is fixed to the bottom of the water through the fixed anchor. The floating rod is provided with a water sampling port communicated with the water inlet of the water tank, and the floating rod is connected to the floating buoy floating on the water surface; a water pump is arranged in the water tank, and the water outlet of the water tank is sent to the ground monitoring station through a pipeline; the water sampling port is located below the water surface.
[0006] In the prior art, in order to realize the change of the floating rod with the water level, the structural design of the floating rod is usually in two forms. One is that one end of the floating rod is provided with a flexible hose, which is connected to the water inlet of the water tank through the flexible hose; the other is that the floating rod is a telescopic rod.
[0007] The depth range of the water body collected by the existing floating rod structure is still limited. This is because the telescopic floating rod is made of hard material, and the adjustable range is limited by its own length; while the floating rod connected to the water tank through a flexible hose is limited by the length of the flexible hose. The floating rod is subjected to the pulling force of the water tank and is located at the set sampling position. When the flexible hose is too long, the floating rod is easily disturbed by the water flow and deviates from the set sampling position; when the flexible hose is too short, the sampling depth of the floating rod is limited. Summary of the Utility Model
[0008] The purpose of the utility model is to provide a novel floating rod structure of a floating rod bottom - sediment water sampler to improve the collection depth range of the floating rod bottom - sediment water sampler.
[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0010] A novel floating rod structure of a floating rod bottom - sampling water sampler, comprising a floating rod and a connecting hose. The floating rod is a hollow rod, with a water sampling port provided on the floating rod. A filter is provided inside the floating rod to filter the water sample entering through the water sampling port. A floating buoy located on the water surface is connected to the floating rod; one end of the floating rod is provided with a water outlet. One end of the connecting hose is sleeved on one end of the floating rod, and the other end of the connecting hose is communicated with the water inlet of the water tank. The connecting hose is arranged on a hose storage rack. The hose storage rack includes a limiting plate and a rotating shaft; the rotating shaft is rotatably connected between two limiting plates, and the two limiting plates are connected as a whole through a connecting rod; one end of the rotating shaft extends into a motor protection shell, and a motor is provided inside the motor protection shell. The output shaft of the motor is connected to the rotating shaft through a gear set, and the connecting hose is wound around the rotating shaft; the gear set includes a large gear and a small gear; the large gear is coaxially connected to the rotating shaft, the small gear is coaxially connected to the output shaft of the motor, and the large gear meshes with the small gear; the gear ratio of the large gear to the small gear > 1.
[0011] As a preferred technical solution, a hose interface is provided on the outer wall of the rotating shaft for connecting to one end of the connecting hose, and the other end of the connecting hose is retracted and extended; a fluid passage is provided inside the rotating shaft, one port of the fluid passage is the hose interface, and the other port of the fluid passage is the end of the rotating shaft extending into the motor protection shell.
[0012] A connecting pipe is fixed inside the motor protection shell. One end of the connecting pipe extends out of the installation surface of the motor protection shell and is communicated with the water inlet of the water tank. The other end of the connecting pipe is rotatably connected to one end of the rotating shaft through a rotary joint.
[0013] As a preferred technical solution, the hose storage rack is detachably connected to the outer wall of the water tank through bolts.
[0014] As a preferred technical solution, the motor is a DC brushless motor with an internal control chip connected to a Hall element.
[0015] As a preferred technical solution, the gear ratio of the large gear to the small gear is 5:1.
[0016] Compared with the prior art, the present utility model has the following beneficial effects:
[0017] By providing a hose storage rack on the outer wall of the water tank as a carrier to retract and extend the hose, the retraction and extension of the connecting hose are adjusted according to the water depth, so that the pay - out length of the connecting hose matches the water depth. The connecting hose wound on the hose storage rack of the connecting hose can have a longer pay - out length, thus greatly increasing the adjustment range. Description of the Drawings

[0024] Embodiment
[0025] As Figure 3 shown, a new floating rod 12 structure of a floating rod 12 bottom sediment water sampler includes a floating rod 12, a connecting hose 5, and a hose storage rack.
[0026] The same as the prior art, the floating rod 12 is a hollow rod. A water intake port is provided on the floating rod 12. A filter is provided inside the floating rod 12 to filter the water sample entering from the water intake port, preventing large impurities from entering the water tank 11 and damaging the water pump inside the water tank 11. A floating buoy 13 located on the water surface is connected to the floating rod 12; one end of the floating rod 12 is provided with a water outlet. One end of the floating rod 12 is sleeved with one end of the connecting hose 5, and the other end of the connecting hose 5 is communicated with the water inlet of the water tank 11.
[0027] Different from the prior art, as Figure 3 shown at A in, the connecting hose 5 is arranged on the hose storage rack.
[0028] As Figures 1 - 2 shown, the hose storage rack is detachably connected to the outer wall of the water tank 11 by bolts. The hose storage rack includes a limit plate 2 and a rotating shaft 7; a rotating shaft 7 is rotatably connected between two limit plates 2. The two limit plates 2 are connected into a whole by a connecting rod 3.
[0029] One of the limit plates 2 is fixedly connected to the protection shell of the motor 6. One end of the rotating shaft 7 is introduced into the protection shell of the motor 6.
[0030] Inside the protective housing of the motor 6 is provided with a motor 6. The output shaft of the motor 6 is connected to one end of a rotating shaft 7 through a gear shaft, driving the rotating shaft 7 to rotate relative to the limit plate 2.
[0031] The connecting hose 5 is wound around the rotating shaft 7 and is taken in and out with the rotating shaft 7 as a carrier. The connecting hose 5 is a shaped hose; that is, the internal flow channel remains unobstructed after it is wound around the rotating shaft 7.
[0032] In some embodiments, the motor 6 is a DC brushless motor 6 with an internal control chip connected to a Hall element, which is used to detect the number of rotations of the motor 6, so as to roughly determine the length of the connecting hose 5 taken in and out.
[0033] In some feasible embodiments, the protective housing of the motor 6 is detachably connected to the outer wall of the water tank 11, and a wire passing hole is provided on the protective housing of the motor 6. The control power supply wire of the motor 6 is pulled into the water tank 11 through the wire passing hole and is connected to the power supply circuit of the original water pump. A sealing ring is provided between the control power supply wire and the wire passing hole.
[0034] Specifically, the motor 6 is connected to the rotating shaft 7 through a gear set; one end of the rotating shaft 7 extends into the protective housing of the motor 6; the gear set includes a large gear 8 and a small gear 9; the large gear 8 is coaxially connected to the rotating shaft 7, the small gear 9 is coaxially connected to the output shaft of the motor 6, and the large gear 8 meshes with the small gear 9; the gear ratio of the large gear 8 and the small gear 9 is preferably 5:1.
[0035] In this embodiment, the reason for using a gear set to connect the motor 6 and the rotating shaft 7 is that in the case of a relatively deep underwater depth, a relatively large water pressure will cause the rotating shaft 7 to require a relatively large torque to rotate. The gear ratio of the large and small gears 9 of the gear set can provide a higher torque, which is more suitable for the deep water environment.
[0036] Furthermore, since the hose is wound around the rotating shaft 7 and will rotate with the rotating shaft 7, but one end of the hose needs to remain connected to the water inlet of the water tank 11, and the hose storage rack is fixed on the water tank 11 to stabilize the position, therefore, when the rotating shaft 7 rotates, a single-end take-in and out tube is required.
[0037] Based on the above technical requirements, this embodiment also has the following design:
[0038] On the outer wall of the rotating shaft 7 is provided a hose interface 10 for connecting to one end of the connecting hose 5, and the other end of the connecting hose 5 is taken in and out. Inside the rotating shaft 7 is provided a fluid channel 14. One port of the fluid channel 14 is the hose interface 10, and the other port of the fluid channel 14 is the end of the end of the rotating shaft 7 extending into the protective housing of the motor 6.
[0039] Through this structural design, one end of the hose rotates with the rotating shaft 7, thereby realizing the take-in and out of the other end of the hose. The hose sends the water sample into the fluid channel 14 located on the central axis.
[0040] Inside the protective housing of the motor 6, a connecting pipe is fixed by a fixing bracket. One end of the connecting pipe extends out of the mounting surface of the protective housing of the motor 6 and is used to communicate with the water inlet of the water tank 11. The other end of the connecting pipe is rotatably connected to one end of the rotating shaft 7 (the port of the fluid passage 14) through a rotary joint 15. The water sample is sent into the water tank 11 through the connecting pipe.
[0041] According to the above embodiments, the present utility model can be well implemented. It should be noted that on the premise of the above structural design, in order to solve the same technical problems, even some non-substantive improvements made to the present utility model also fall within the protection scope of the present utility model.
