Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water conservancy engineering technology, and more specifically, it relates to an adjustable water quality sampling device. Background Technology
[0002] When water conservancy projects test the water quality of rivers and other water sources, they need to use adjustable water quality sampling devices. After adjusting the sampling mode of the water quality sampling device, the staff places the sampling bottle inside the water quality sampling device, and the water quality sampling device uses a water pump to draw water into the sampling bottle for testing.
[0003] According to CN202322246265.7, this application discloses a river water quality sampling device, which relates to the field of water quality sampling technology. The device includes a housing. A base plate is connected to the bottom surface of the inner wall of the housing via a sliding mechanism. Four grooves are formed on the top surface of the base plate. Four return springs are circumferentially connected inside the grooves. A pad is connected above the return springs, and a sampling cylinder is connected above the pad. A weighing sensor is connected inside the grooves. A servo motor is connected to the middle position below the base plate via a rotating mechanism. A partition, a microcontroller, and a signal receiver are connected from top to bottom to the left side wall of the housing. The device includes the pad, weighing sensor, return springs, base plate, and servo motor. After a water sample is introduced into the sampling cylinder, the weighing sensor is triggered. When the weight reaches a warning value, the operator controls the servo motor to rotate the base plate, removing the sampling cylinder filled with water sample from under the drain pipe for easy collection of the next water sample.
[0004] Based on the above, existing water quality sampling devices generally use a groove structure to place the sampling bottle. When using water samples made of the sampling bottle material, staff need to first place the sampling bottle inside the groove and then align the sampling outlet with the sampling bottle. Since the sampling outlet is located inside the groove, it is difficult for staff to quickly align the sampling bottle with the sampling outlet, which affects the efficiency of water quality collection. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides an adjustable water quality sampling device. This addresses the issue that existing water quality sampling devices typically use a groove structure to place the sampling bottle. When using water samples made of the sampling bottle material, staff need to first place the sampling bottle inside the groove and then align the sampling outlet with the sampling bottle. Since the sampling outlet is located inside the groove, it is difficult for staff to quickly align the sampling bottle with the sampling outlet, thus affecting the efficiency of water quality collection.
[0006] The purpose and effectiveness of this adjustable water quality sampling device are achieved through the following specific technical means:
[0007] An adjustable water quality sampling device includes a sampling body, a sampling cover, a sampling water pump, an inlet pipe, a control knob, a control switch, a movable base, a sampling pipe, a sampling moving mechanism, and a bottle placement mechanism. The sampling cover is hinged to the front end face of the sampling body. The sampling water pump is fixedly connected to the upper side of the front end face of the sampling body.

The movable base is slidably connected to the lower side of the inner end face of the sampling body. The sampling pipe is slidably connected to the front side inside the sampling body. The sampling moving mechanism is located inside the sampling body. Two sets of bottle placement mechanisms are provided, each located inside the movable base.
[0008] Furthermore, the sampling moving mechanism includes: a moving chute and a moving slider; there are two sets of moving chute, which are respectively opened on the lower side of the inner end face of the sampling body; there are two sets of moving slider, which are respectively fixedly connected to the rear side of the left and right end faces of the moving base, and the two sets of moving slider slide inside the two sets of moving chute.
[0009] Furthermore, the sampling moving mechanism also includes: a moving connecting rod and a sampling connecting rod; the moving connecting rod is fixedly connected to the upper end face of a set of moving sliders on the left side, and the moving connecting rod is slidably connected to the left side inside the sampling body; the sampling connecting rod is fixedly connected to the upper side inside the sampling body, the moving connecting rod and the sampling connecting rod are fixedly connected, and the sampling connecting rod is fixedly connected to the middle position of the rear end face of the sampling pipe.
[0010] Furthermore, the sampling moving mechanism also includes: a water outlet hose, a sampling nozzle, and a control valve body; the water outlet hose is fixedly connected to the outlet of the sampling water pump on the left side; two sets of sampling nozzles are provided, and the two sets of sampling nozzles are fixedly connected to the left and right sides of the lower end face of the sampling pipe, and the two sets of sampling nozzles slide on the left and right sides inside the sampling body; two sets of control valve bodies are provided, and the two sets of control valve bodies are fixedly connected to the left and right sides of the upper end face of the sampling pipe.
[0011] Furthermore, the bottle placement mechanism includes: placement grooves and extrusion sliders; the placement grooves are formed on the left and right sides of the upper end face of the movable base; there are four sets of extrusion sliders, which are slidably connected inside the movable base and slide inside the placement grooves.
[0012] Furthermore, the bottle placement mechanism also includes: compression springs and compression arcs; there are four sets of compression springs, which are fixedly connected inside the movable base and elastically connected to the outer end faces of four compression sliders; there are four sets of compression arcs, which are respectively opened on the inner end faces of four compression sliders and are arc surface structures.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model employs a sampling moving mechanism, allowing staff to open the sampling cover and pull the moving base out of the sampling body. The moving base moves to the outside of the sampling body, which in turn moves the sampling pipe to the outside of the sampling body, making it convenient to place the sampling bottle on the moving base. This avoids the problem of inconvenient operation when collecting water samples by placing the sampling bottle inside the sampling body, which requires aligning the sampling bottle and the sampling nozzle. This makes it easier for staff to use the water quality sampling device to collect water samples.
[0015] This invention employs a bottle placement mechanism, allowing staff to place sampling bottles inside the placement groove. A compression spring drives a compression slider to slide, which in turn holds the sampling bottle in place, ensuring relative stability within the groove. When the movable base moves, it steadily moves the sampling bottle, preventing instability and tilting issues caused by the bottle's position on the movable base. This makes it convenient for staff to place the sampling bottle using the movable base. Attached Figure Description
