Description

Spiral mud collecting device for estuary wetland

Technical Field

The utility model relates to a bed mud field of gathering of estuary wetland, in particular to a spiral mud sampling device for estuary wetland.

Background

The wetland ecosystem has the functions of protecting biological diversity, regulating runoff, improving water quality and the like, and is an irreplaceable precious natural resource. However, in recent years, wetland soil is generally polluted along with discharge of a large amount of industrial wastewater and domestic sewage. The element composition in the soil is changed greatly, and the heavy metal content is higher and higher. The bottom mud condition of the estuary wetland is monitored, and the collection and detection are carried out, so that data support can be provided for the treatment and protection of the environment.

Because the wetland is muddy, the traditional resistance that the collection pipe was transferred or was taken out and receive is big, and need hold the collection mouth with the hand and prevent that the mud appearance from droing, so the whole hard of collection process. The drill bit and the pipe body of the collecting pipe are provided with threads and enter the mud surface in a rotating mode, and the drill bit and the inner cavity are provided with slopes, so that mud samples can be effectively prevented from falling off. The rotation of the screw thread can reduce the resistance caused by the mud around, and the power device moves up and down while rotating, so that the technical problem in the traditional collection method can be well solved.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the problem of current artifical bed mud collection technique, a spiral mud sampling device for estuary wetland is provided. Compare with using the tradition to adopt the mud pipe, use this spiral mud sampling device can carry out the sediment collection more easily.

A spiral mud collecting device for estuary wetland comprises a support, a collecting pipe and a power device.

The support plays the effect of supporting whole device, and three spinal branch vaulting poles and support between the round platform, bracing piece and the support foot stool by hinged joint, can freely angle regulation to can steadily stand in the collection environment of different situations.

The collection tube includes a drill bit and a tube body.

The power device comprises a steering wheel, a reduction box and a screw nut.

The steering wheel is fixed on the bracket through a bearing.

The reduction gearbox is fixed below the supporting circular truncated cone through four rods.

The screw nut is fixed on the bracket through the supporting plate and the bearing.

Further, the drill bit and the pipe body of the collecting pipe are provided with threads and can rotate to enter the mud surface.

Furthermore, the inner cavity of the collecting pipe body is a truncated cone-shaped inner hole with a small lower part and a large upper part, so that the mud sample can be effectively prevented from falling off.

Further, the collecting pipe is connected with the screw nut through threads and can be detached, and the mud sample is taken out from the upper side.

Furthermore, the power device can enable the collecting pipe to rotate and lift at the same time through the matching of the gear and the screw nut.

Furthermore, the power device utilizes the function that the speed reducer can increase the torque, the torque applied to the steering wheel by hands can be increased and then transmitted to the nut of the screw-nut pair, and then the nut transmits the torque to the screw rod which is in screw fit with the nut, so that the screw rod obtains larger downward pressure, and the collecting pipe obtains larger downward pressure on the mud.

Detailed Description

The following detailed description of the embodiments of the present invention, with reference to the accompanying drawings, provides detailed embodiments and specific operations. The examples are preferred, but not all examples of the invention.

Step 1: a spiral mud collecting device for estuary wetland comprises a support, a power device and a collecting pipe. First, the parts of the device are checked to ensure that the device can work normally.

Step 2: the device is stably placed on the collecting surface by adjusting the angles of the three support rods and the support foot seats.

And step 3: and (4) mounting the collecting pipe on the lead screw nut, and preparing for operation.

And 4, step 4: the steering wheel is rotated and a force is applied downwards to drive a gear in the reduction box, and the gear drives the screw nut. The nut rotates but does not move, so that the screw rod is forced to move downwards together with the collection tube connected with the screw rod while rotating, and the screw rod enters the mud layer in a spiral mode. The mud sample enters the inner cavity of the collecting pipe from the drill bit. And when the threads completely enter the mud, the mud sample is collected.

And 5: after collection, the steering wheel is rotated in the opposite direction, the collection pipe is exposed out of the mud surface, and the collection pipe is taken down for storage. Adjusting the position, repeating the steps, and installing a new collecting pipe for collecting the mud sample.

Step 6: and taking the collecting pipe down from the main shaft where the lead screw is positioned, taking out a mud sample from the upper part of the collecting pipe, and detecting in a laboratory.

The above description is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
