Description

Technical Field

[0001] The utility model belongs to the technical field of environmental detection, and in particular relates to a rainwater collection and sampling device for environmental detection. Background Art

[0002] Rainwater may be polluted during the urbanization process. In order to understand the degree of rainwater pollution and protect rainwater resources, it is usually necessary to collect rainwater samples at different times to detect the characteristics and water quality of rainwater at different times. Existing rainwater collection equipment can usually only receive rainwater once, and it is necessary to transfer this part of rainwater before receiving the next rainwater, and the sampling efficiency is low.

[0003] A Chinese patent with publication number CN217896637U discloses a rainwater collection device for atmospheric environment detection. The solution includes a fixed cylinder, a rain collecting hopper is arranged above the fixed cylinder, a tray is rotatably arranged below the fixed cylinder, a plurality of bottom cylinders are arranged on the top of the tray, and a first conduit, a water valve and a second conduit are arranged on the side wall of the fixed cylinder. The above scheme enables the rain collecting hopper to collect rainwater, and uses the rotating tray to sequentially send the plurality of bottom pipes to the bottom of the second conduit, and cooperates with the switch water valve to make the rainwater flow into the corresponding bottom cylinder through the first conduit, the water valve and the second conduit, thereby achieving the purpose of collecting rainwater in different time periods.

[0004] When the above solution is used, it is necessary to close the water valve after the bottom tube is separated from the second conduit, and to open the water valve again after the next bottom tube moves under the second conduit, and the operation steps are relatively complicated. Utility Model Content

[0005] The utility model aims to provide a rainwater collection and sampling device for environmental detection, so as to solve the problem that the operation steps in the above scheme are relatively complicated.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A rainwater collection and sampling device for environmental detection comprises a frame body, a water distribution pipe and a collecting cup, the frame body having an inner cavity, a water collecting bucket being fixedly inserted on the top of the frame body and a motor being fixedly arranged thereon, a plurality of limit grooves being recessed along the circumference of the water collecting bucket at the bottom of the inner cavity, the top of the water distribution pipe being rotatably connected to the bottom of the water collecting bucket along the axial direction of the water collecting bucket, a ball check valve being arranged at the bottom of the water distribution pipe, the water distribution pipe being connected to the motor through a transmission assembly, the motor being able to drive the water distribution pipe to intermittently rotate along the axial direction of the water collecting bucket through the transmission assembly, a plurality of collecting cups being arranged and being slidably embedded in corresponding limit grooves respectively, the top of the collecting cup being open and being fixedly provided with a protrusion, the protrusion being able to trigger the ball check valve.

[0008] The principle and effect of this technical solution:

[0009] Slide and insert multiple collecting cups into corresponding grooves one by one. When it rains, place the frame body in an open area. Rainwater collects in the water collecting bucket and flows into the water distribution pipe, driving the motor to drive the water distribution pipe to rotate intermittently through the transmission assembly. When the bottom of the water distribution pipe is directly above the collecting cup, the water distribution pipe stops rotating, the protrusion lifts the ball in the ball check valve to open the ball check valve, and the rainwater in the water distribution pipe flows into the collecting cup through the ball check valve. When the water distribution pipe rotates again, the protrusion disengages from the ball check valve, and the ball falls freely to close the ball check valve, and the newly fallen rainwater accumulates in the water distribution pipe.

[0010] Through the above arrangement, when the bottom of the water distribution pipe moves to the top of the collecting cup, the ball-bearing one-way valve is automatically opened to inject rainwater into the water distribution pipe, and when the bottom of the water distribution pipe leaves the top of the collecting cup, the ball-bearing one-way valve is automatically closed to accumulate newly fallen rainwater, thereby achieving the purpose of continuously collecting rainwater samples at different time periods, while simplifying the operating process and improving sampling efficiency.

[0011] In the utility model, the transmission assembly includes a groove wheel and a dial. The groove wheel is fixedly arranged at the top of the water distribution pipe along the axial direction of the water collecting bucket, and a through hole is arranged along the axial direction of the water collecting bucket. The dial is fixedly connected to the output end of the motor, and a round pin that cooperates with the groove wheel is eccentrically fixed on the top of the dial.

[0012] In the utility model, a bearing is arranged at the bottom of the water collecting bucket along its axial direction, the bottom of the water collecting bucket is fixedly connected to the top of the inner ring of the bearing, and the top of the groove wheel is fixedly connected to the bottom of the outer ring of the bearing.

[0013] The principle and effect of this technical solution:

[0014] The motor drives the dial to rotate to drive the groove wheel to rotate intermittently, and then drives the water distribution pipe to rotate intermittently. Through the above arrangement, the purpose of intermittent rotation of the water distribution pipe can be achieved, and at the same time, the friction between the groove wheel and the bottom of the water collecting bucket can be reduced, the smoothness of rotating the water distribution pipe can be improved, and the practicality of the utility model can be improved.

[0015] In the utility model, a filter is fixedly arranged in the horizontal direction inside the water collecting bucket. When there are impurities in the rainwater, the filter blocks the impurities above the filter. The above arrangement can prevent the impurities carried by the rainwater from flowing into the collection cup, thereby improving the accuracy of the detection result.

[0016] In the utility model, the water distribution pipe is arranged at an angle, so that rainwater can be prevented from accumulating in the water distribution pipe after the ball valve is opened, thereby improving the accuracy of the detection result.

[0017] In the present invention, the collection cup has scale lines. Through the above arrangement, the rainfall per unit time can be measured, thus broadening the application scenarios of the present invention.

[0018] In the utility model, the bottom of the frame body is provided with walking wheels, and the top of the frame body side wall is provided with a push handle. Through the above arrangement, it is convenient for sampling personnel to transfer the frame body, thereby improving the practicality of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS
