Description

Water sampling device

Technical Field

The utility model relates to the field of sampling devices, in particular to a water sampling device.

Background

The water body detection test comprises the detection of indexes such as PH value, turbidity, nitrogen and phosphorus content, PH value and the like of the water body. The water sampling is the pretreatment work of the water detection test.

For sampling some water bodies with drop, for example, when sampling a water pool at the bottom of a shore, since the drop from the top of the shore to the bottom of the shore is 5-8 meters, in order to ensure the safety of sampling personnel, the sampling personnel generally stand on the top of the shore for sampling, rather than reach the bottom of the shore for sampling, so that one water body cannot be reached like the normal sampling. When sampling, the bucket tied with the rope is used as a tool, the bucket is thrown into the water body at the bottom of the shore from the top of the shore, and then the bucket is towed to the top of the shore through the rope, so that sampling is completed.

The above-mentioned sampling method has the following drawbacks: 1. the position of throwing the barrel into the water body every time is completely dependent on the strength of sampling personnel, the sampling position point is uncontrollable, the randomness is very strong, and if the sampling personnel only want to acquire one water body independently, the barrel throwing is very difficult to realize, and the barrel throwing is often needed for many times. 2. The barrel can only take the water body on the surface layer of the water body, the barrel is full of water in the process of sinking water, and the water body with a certain depth can not enter the barrel any more, so that the water body with a certain depth can not be collected. 3. Laborious, each time the barrel is dragged, the manpower is consumed.

Disclosure of utility model

The water sampling device can sample water bodies in designated areas, can also sample water bodies in different depths, and does not depend on manpower.

In order to achieve the above purpose, the water sampling device of the utility model comprises a bracket fixed on the land top and the ground, a retraction roller is rotatably connected on the bracket, and an extension plate is connected on the bracket; the extension plate is provided with a strip-shaped hole extending towards the water body direction; the device also comprises a walking roller, wherein the walking roller can move along the extending direction of the strip-shaped hole; the winding and unwinding roller is wound with a pull rope, the free end of the pull rope winds around and downwards from the upper end of the walking roller, and the free end of the pull rope is fixed with a balancing weight; the support is connected with a water bucket and a water pump, the water outlet end of the water pump is communicated with the water bucket, the water inlet end of the water pump is connected with a hose, and one end of the hose, far away from the water pump, is connected with a balancing weight.

Further, the end part of the walking roller is fixedly connected with a gear, and the axis of the gear is coincident with the axis of the walking roller; the lower surface wall in bar hole is fixed with the rack, the rack extends along extension board extending direction and sets up, gear and rack meshing, movable card is equipped with the limiting plate on the extension board, the limiting plate can be followed extension board extending direction and removed, be fixed with the spliced pole on the gear, the spliced pole axis coincides with the axis of gear, the spliced pole rotates to be connected on the limiting plate, be equipped with the second motor on the limiting plate, the non-pivot end of second motor is fixed on the limiting plate, the pivot of second motor passes the limiting plate and with spliced pole fixed connection, the pivot and the spliced pole fixed connection of second motor, the pivot of second motor can rotate for the limiting plate.

The gear and the walking roller are driven to integrally rotate by the second motor, and the gear is meshed with the rack, so that the gear and the walking roller can move along the direction of the rack as a whole while rotating. Because the walking roller moves, the vertical section part of the pull rope moves along the moving direction of the walking roller, so that the balancing weight connected with the free end of the pull rope gradually adjusts the position until the balancing weight can reach the upper part of the water body to be sampled. And the balancing weight is gradually lowered to contact the water surface by rotating the winding and unwinding rollers, and the water pump is used for realizing sampling by pumping water. The position of the balancing weight can be repeatedly adjusted along the extending direction of the extending plate without a water throwing barrel, and the sampling area can be reached more accurately.

Further, the limiting plate is located on the outer side of the extension plate.

The limiting plate is arranged on the outer side of the extending plate, the free end of the pull rope is not easily affected by the limiting plate, and the free end of the pull rope cannot be clamped by the limiting plate in the moving process of the walking roller, so that the situation that the free end of the pull rope cannot be lifted is avoided.

The sliding direction of the limiting plate is more limited due to the sliding blocks and the sliding grooves, so that the limiting plate can be ensured to stably move and not to rotate around the axis of the walking roller.

Further, the extension plate is detachably connected to the bracket.

When the area to be sampled is far off-shore, the extension plate, the walking roller, the gear, the second motor and other parts can be detached from the bracket at the same time, and the longer extension plate and the related parts can be replaced. The extension plate is arranged to be detachable from the bracket, so that the purpose of conveniently replacing extension plates of different sizes is achieved, and the extension plate is suitable for water bodies farther away from the shore.

Further, the water pump and the water bucket are detachably connected to the bracket.

The water pump and the water bucket are detached from the bracket for carrying, so that the overall weight of the equipment can be reduced in the carrying process, and the carrying is convenient. After the bucket is full, the bucket can be detached from the bracket, and the other empty bucket is replaced, so that the whole device is not required to be replaced, and the use is convenient.

Further, a first motor is arranged on the support, the non-rotating shaft end of the first motor is fixed on the support, the rotating shaft of the first motor is fixedly connected with the winding and unwinding roller, and the axis of the rotating shaft of the first motor coincides with the axis of the winding and unwinding roller.

The first motor is used for driving the winding and unwinding rollers to rotate, so that the winding and unwinding rollers are prevented from being manually rotated by a person, and the purpose of labor saving is achieved.

Further, a clamp for fixing the hose is fixed on the balancing weight.

The clamp can guarantee that the end of the hose and the balancing weight can not move relatively, so that the end of the hose and the configuration block can move synchronously, and further the sampling depth and the sampling place can be accurately reached along with the balancing weight. If no clamp is provided, the hose and the balancing weight are moved relatively, and the end of the hose cannot accurately reach the sampling position point.

Advantageous effects
