Description

An anchor type surface sediment collection device

technical field

The utility model relates to an anchor type surface sediment collection device, which is a collection device applied to surface sediments in oceans, lakes and other water areas.

technical background

Surface sediments in water areas are the comprehensive reflection of many factors such as hydrology, physics, chemistry, biology, topography, provenance, geological structure and even sea level changes in the process of sediment formation. It is an indispensable scientific research object and is widely used in practical fields such as water ecological environment assessment and pollution accident investigation. Therefore, the development of a scientific and efficient sediment collection device has dual meanings of science and reality.

Traditional columnar dredgers and grab dredgers use larger specific gravity, such as stainless steel or stainless steel embedded with lead weights as raw materials, and use the difference in gravity and buoyancy of the device from the surface of the water body to the bottom of the water body to obtain sufficient momentum. , inserted into the seabed, riverbed or lakebed to a certain depth, and then the sediment is sealed in the device by the "door closing" mechanism, so as to obtain the required sediment samples. Using the downward impulse of the device, this type of mud extraction device has two obvious defects: first, in the strong current area, most of the vertical downward impulse of the device will be offset by the transverse horizontal impulse brought by the ocean current , when the device touches the bottom, especially the impulse is not enough, it is impossible to collect enough samples, or even get nothing, and the sampling efficiency is low; secondly, in order to overcome the constraints of unfavorable factors such as ocean currents and terrain, this type of mud mining device has to increase the size of the device. The self-weight of the machine must be equipped with lifting equipment such as an electric winch to obtain a sufficient impulse. At the same time, the work intensity and difficulty of the operator are increased. Therefore, a portable, efficient and easy-to-operate surface sediment collection device of the utility model is very beneficial and very necessary.

Aiming at the deficiencies of the above-mentioned existing technologies, fully considering the characteristics of oceans, lakes and other waters, and meeting the requirements of scientific and practical applications, an anchor-type surface sediment collection device is provided to improve the collection efficiency of surface sediments and reduce operating costs. The working intensity and difficulty of the personnel, the technical scheme is as follows:

An anchor type surface sediment collection device, comprising a V-shaped groove, a balance orientation device, a ballast device and an automatic opening and closing top cover device, the balance orientation device is fixed at the bottom of the V-shaped groove, and the ballast The device is fixed at the top center of the V-groove.

Further, the V-shaped groove is welded together by four stainless steel plates, and the opening angle is 90 degrees.

Further, the bottom end of the V-shaped groove is provided with an annular sleeve and a bayonet pin.

Further, a 180-degree bidirectional shaft is provided at one end of the ballast device close to the V-shaped groove.

Further, the other end of the ballast device is fixed with an arched ring.

Further, the automatic opening and closing top cover device is connected to both sides of the V-shaped groove through a mechanical linkage.

Further, the device for automatically closing and opening the top cover includes a lower cover and an upper cover.

Further, the balance orientation device is a balance orientation rod.

Further, the ballast device is a ballast rod.

Further, the opening of the V-shaped groove is 25cm wide.

The utility model adopts the working principle similar to a ship's anchor, has high sampling success rate, large sample volume, simple structure, strong practicability, and is conducive to popularization and use. It can be used by scientific research personnel such as oceanography, geology, and environmental science to collect surface sediments , the success rate of surface sediment collection is over 95%.

Description of drawings

Fig. 1 is a structural schematic diagram of the anchor type surface sediment collection device of the present invention.

specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the anchor type surface sediment collection device of the present utility model comprises " V " type groove 3, balance directional rod 6, ballast rod 5 and automatic opening and closing top cover device, " V " type groove 3 consists of 4 pieces of stainless steel plates are welded together on one side, and the opening angle is 90 degrees; the bottom end of the "V" groove 3 is welded with 2 ring sleeves and provided with bayonet pins 8, which are used to fix the balance and orientation rod 6; the "V" groove At the center of the top of 3, the ballast rod 5 is welded to pass through the top center of the "V" groove 3, and a 180-degree bidirectional shaft 4 is set at one end close to the "V" groove 3, and an arched ring is welded at the other end It is used to fix the rope; the two sides of the "V" groove 3 are connected with the mechanical linkage 7 to automatically close the top cover device, including the lower cover 1 and the upper cover 2 (during sampling, the upward thrust of the lower cover 1 in contact with the bottom of the water will Open the upper cover 2 to carry out the mud mining process, the lower cover 1 is separated from the bottom of the water, and the upper cover 2 covers the "V"-shaped groove 3 under the action of gravity to prevent the mud sample from being washed away by water). When collecting surface sediments, the device is thrown into the water body. Due to the counterweight of the ballast rod 5, the center of gravity of the collector is suspended on the ballast rod 5, and the "V" groove 3 forms a downward angle, and then Drag the rope, and at this time, the balance directional rod 6 prevents the "V" groove 3 from swinging left and right. With the sliding of the "V" groove 3, the groove body will incorporate the surface sediment into it. When the rope drags the upward When the force and the ballast reach a certain angle, the "V"-shaped groove will break away from the bottom of the water and carry the surface sediment up to complete the collection of surface sediment. The opening of the "V"-shaped groove is 25cm wide. After a collection work is completed, there will be silt and other adhesions on the surface of the device and the "V"-shaped groove, which need to be rinsed with fresh water and reused.

The anchor-type surface sediment collection device of the utility model has been proved by the sampling of strong current near shore and offshore waters with a depth of 5m~85m in the north of Zhoushan, and the sampling success rate is more than 95%, which effectively overcomes the impact of strong ocean current and water depth on the surface sediment. Due to the restrictions on the collection of materials, the self-weight of the device is reduced by more than two-thirds compared with the common grab dredger, which reduces the labor intensity of the operators, and the operation is very simple, which improves the work efficiency. In summary, the utility model is simple in structure, practical and convenient, and can be popularized and applied.
