Description

Technical Field

[0001] This utility model relates to the field of water sampling technology, and in particular to a water sampling device for natural water bodies that can perform stratified sampling. Background Technology

[0002] A water sample is a representative portion taken discontinuously or continuously from a specific body of water to test for various specified characteristics of the water.

[0003] A search of Chinese patent publication number CN209542171U reveals a portable water sampling device.

[0004] The above technical solution includes a top plate and a sampling assembly. The top surface of the top plate is equipped with a solenoid valve control switch. Two clamping plates are symmetrically arranged on the bottom surface of the top plate, and a rotating wheel is rotatably installed between the two clamping plates. A pull rope is wound around the rotating wheel. A locking bolt for locking the pull rope is located in the middle of the top plate, and the end of the pull rope is connected to the sampling assembly. The sampling assembly includes several sample boxes connected in series. The uppermost sample box is connected to the end of the pull rope. Each sample box includes a box body, an outlet pipe, and an inlet pipe. The top of the box body has an outlet pipe with a sealing cap at its top. The top of the side plate of the box body has an inlet pipe containing a solenoid valve. The solenoid valve is connected to a solenoid valve control switch wire. Each sample box has a lifting ring on its bottom surface and a connecting chain on its top surface. This utility model has a simple structure, is easy to carry, and provides convenient and quick sampling.

[0005] However, in the above-mentioned scheme, the sampling position cannot be flexibly adjusted. In cases where there are undercurrents in the water, the depth of the water sampler will change as the weight of the water sampler increases after sampling, causing it to tend to be vertical and resulting in inaccurate sampling depth.

[0006] To address this, we propose a stratified water sampling device for natural water bodies. Utility Model Content

[0007] The present invention aims to solve the technical problems existing in the prior art and provide a water sampling device for natural water bodies that can be sampled in layers.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a water sampling device for natural water bodies that can be sampled in layers, including a floating object, a traction rope fixedly connected to the lower end of the floating object, an adjustment component fixedly connected to the lower end of the traction rope, a water sampler threadedly connected to the lower end of the adjustment component, and several sets of the adjustment component and the water sampler arranged in sequence, with a counterweight fixedly connected to the end of the water sampler via the traction rope, and the counterweight having a built-in positioning chip;

[0009] An adjustment assembly includes a sealing shell, a rotating shaft rotatably connected inside the sealing shell, a traction wheel sleeved on the rotating shaft, a traction rope wound inside the traction wheel, the end of the traction rope extending out of the sealing shell, and a nut fixedly connected to the end of the traction rope. The nut is threadedly connected to a threaded pipe provided at the upper end of the water dispenser, and a threaded pipe is also provided at the upper end of the sealing shell.

[0010] Preferably, a driven wheel is also sleeved on the drive shaft. The driven wheel is connected to the power wheel via a drive belt. One end of the power wheel is fixedly connected to the output end of the servo motor.

[0011] Preferably, the lower end of the sealing shell has an opening for the extension of the traction rope, and a first sealing gasket that is interference-fitted with the traction rope is sealed inside the opening, and a second sealing gasket that is sealed outside the first sealing gasket is covered by a second sealing gasket.

[0012] Preferably, the water dispenser includes a tank, with a water inlet pipe connected to one side of the tank. The water inlet pipe is equipped with a waterproof electric valve, and a waterproof positioning chip is installed inside the tank.

[0013] Preferably, the upper end of the tank is provided with a water outlet, and a sealing plug is detachably connected to the water outlet.

[0014] Preferably, a traction rope is also provided at the lower end of the tank.

[0015] This invention provides a stratified water sampling device for natural water bodies, which has the following improvements and advantages compared with the prior art:

[0016] (1) This utility model adopts a retractable traction rope, and a rotating shaft is rotatably connected inside the sealed shell. A traction wheel is sleeved on the rotating shaft, and a traction rope is wound inside the traction wheel. The end of the traction rope extends out of the sealed shell, and a nut is fixedly connected to the end of the traction rope.

A driven wheel is sleeved on the transmission shaft. The driven wheel is driven by the power wheel through a transmission belt. One end of the power wheel is fixedly connected to the output end of the servo motor. By setting the traction rope to be wound on the traction wheel, the distance between the water collectors is changed, thereby controlling the water collection depth. The freely detachable threaded connection method allows for free selection of the number of water samples.

[0017] (2) This utility model uses a counterweight and a positioning chip for positioning. The water collector is fixedly connected to the counterweight by a traction rope. The counterweight has a built-in positioning chip. The water collector includes a tank. A water inlet pipe is connected to one side of the tank. A waterproof electric valve is installed on the water inlet pipe. A waterproof positioning chip is installed inside the tank. A water outlet is opened at the upper end of the tank. A sealing plug is detachably sealed inside the water outlet. A traction rope is also installed at the lower end of the tank. By setting the counterweight, the water collector can be kept to be more vertical, thereby reducing the fluctuation range of the water collector.

[0024] The invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0025] Example 1

[0026] Please see Figures 1 to 3Example 1 describes a floating object 10 (a general term used to describe a floating object), whose function is to facilitate retrieval and prevent it from falling into the water. A traction rope 37 is fixedly connected to the lower end of the floating object 10. The exposed length of the traction rope 37 determines the depth. An adjustment component 30 is fixedly connected to the lower end of the traction rope 37. A water sampler 20 is threadedly connected to the lower end of the adjustment component 30. Several sets of adjustment components 30 and water samplers 20 are arranged sequentially, allowing for convenient adjustment of the sampling number. A counterweight is fixedly connected to the end water sampler 20 via the traction rope 37. Counterweight 11, the weight of which can overcome the interference fit between the traction rope 37 and the first sealing gasket 33 and the second sealing gasket 34, has a built-in positioning chip that can send real-time data to onshore monitoring equipment. Adjustment assembly 30 includes a sealing shell 31 to prevent water ingress. A rotating shaft 35 is rotatably connected inside the sealing shell 31, and a traction wheel 36 is sleeved on the rotating shaft 35. The traction rope 37 is wound inside the traction wheel 36. Rotation of the traction wheel 36 retracts or releases the traction rope 37. The end of the traction rope 37 extends out of the sealing shell 31. A nut 42 is also fixedly connected to the end of the traction rope 37. The nut 42 is threadedly connected to the threaded tube 26 at the upper end of the water dispenser 20. A threaded tube 26 is also provided at the upper end of the sealing shell 31. The nut 42 and threaded tube 26 facilitate connection and allow for flexible use of the number of water dispensers 20. A driven wheel 38 is also sleeved on the drive shaft. The driven wheel 38 is driven by a drive belt 40 and a power wheel 39. One end of the power wheel 39 is fixedly connected to the output end of the servo motor 41. The motor 41 is waterproofed and the servo motor 41 is self-locking. The start, stop and direction of the servo motor 41 are controlled by remote control technology. The servo motor has sufficient power and drives the rotation of the traction wheel 36. The lower end of the sealing shell 31 has an opening 32 for the extension of the traction rope 37. A first sealing gasket 33 that is interference-fitted with the traction rope 37 is sealed inside the opening 32. A second sealing gasket 34 is covered and sealed outside the first sealing gasket 33. The first sealing gasket 33 and the second sealing gasket 34 ensure waterproofness.

[0027] In this embodiment, the nut 42 of the adjusting component 30 is threaded into the threaded tube 26 of the water extractor 20, and the water extractor 20 is the opposite. The two are set in sequence. Then, the floating object 10 is placed on the water surface, and then the counterweight 11 and other components are placed in the water. The positioning chip built into the counterweight 11 transmits the position in real time. Then, the servo motor is started, and the servo motor drives the power wheel 39 to rotate. The rotation of the power wheel 39 drives the driven wheel 38 to rotate through the transmission belt 40. The rotation of the driven wheel 38 drives the rotating shaft 35 to rotate. The rotation of the rotating shaft 35 drives the traction wheel 36 to rotate, thereby releasing the traction rope 37, thereby increasing the extension length of the traction rope 37, so as to adjust the water intake depth, which is very convenient to use.

[0028] Example 2

[0029] Please see Figure 1 and Figure 2 Example 2 describes a water dispenser 20 with a counterweight 11 fixedly connected to it via a traction rope 37. The weight of the counterweight 11 can overcome the interference fit between the traction rope 37 and the first sealing gasket 33 and the second sealing gasket 34. The counterweight 11 has a built-in positioning chip. The water dispenser 20 includes a tank 21 with a water inlet pipe 24 connected to one side. Water enters through the water inlet pipe 24, and a waterproof electric valve 25 is installed on the water inlet pipe 24 to control the opening and closing of the water inlet pipe 24. A waterproof positioning chip is installed inside the tank 21 to transmit the position of the water dispenser 20. A water outlet 22 is opened at the upper end of the tank 21, and a detachable sealing plug 23 is installed inside the water outlet 22. The water sample is poured out by opening the sealing plug 23. The water outlet 22 is normally closed by the sealing plug 23. A traction rope 37 is also provided at the lower end of the tank 21 to facilitate the connection between the adjustment component 30 and the counterweight 11.

[0030] In this embodiment, the counterweight 11 is placed in the water. After adjusting the depth of each water dispenser 20, the electric valve 25 is activated individually or together. After the electric valve 25 is opened, water enters the tank 21 from the inlet pipe 24. After the water dispenser 20 is filled with water, its weight increases and it tends to be vertical. The positioning chip sends the position in real time, and then the adjustment component 30 is used to make corrections. After a certain period of time, the electric valve 25 is closed and the device is retrieved.
