Technical Field

[0001] This utility model relates to a collection device, specifically a device suitable for collecting DNA samples from pond sediment under field conditions, belonging to the field of sediment collection technology. Background Technology

[0002] Bottom sediment is typically a mixture of clay, silt, organic matter, and various minerals, formed by the deposition of sediment at the bottom of a water body over a long period of time through physical, chemical, and biological processes and water transport. Bottom sediment with a thickness of 0 to 15 cm is called surface sediment, while sediment thicker than 15 cm is called deep sediment. Bottom sediment collection devices are required for sediment testing and research.

[0003] A search revealed a sediment collection device disclosed in Chinese Patent Publication No. CN217006493U, which includes a handle, a support rod movably connected to the inner wall of the handle, a sampling tube rotatably connected to the bottom end of the support rod, a sampling port on the surface of the sampling tube, and a partition plate fixedly connected to the inner wall of the sampling tube. This device is capable of collecting sediment in layers.

[0004] While the above-mentioned methods can collect sediment in layers, they cannot guarantee that the sediment will smoothly enter the sampling tube from the sampling port when the sediment is hard, resulting in low stability. To address this issue, we provide a device suitable for collecting DNA samples from pond sediment in the field. Utility Model Content

[0005] The purpose of this invention is to provide a suitable device for collecting DNA samples from pond sediment under field conditions in order to solve the above-mentioned problems, thereby addressing the issue that in the prior art, when the sediment is hard, it cannot be successfully collected into the sampling tube, resulting in low stability.

[0008] Preferably, the outer surface of the transmission slide rod is slidably connected to a collection inner cylinder, and the inner wall of the collection inner cylinder is provided with a through groove adapted to the sealing plate. According to the setting of the through groove, pulling down the collection inner cylinder can separate it from the transmission slide rod and the sealing plate.

[0009] Preferably, the top surface of the outer collecting cylinder has a fixing hole, and the top surface of the inner collecting cylinder is fixedly connected to a threaded connecting rod that matches the fixing hole on the top surface of the outer collecting cylinder. The outer surface of the threaded connecting rod is threaded with a fixing nut. By inserting the threaded connecting rod into the fixing hole on the top surface of the outer collecting cylinder, and then rotating the fixing nut onto the surface of the threaded connecting rod, the outer collecting cylinder and the inner collecting cylinder can be effectively fixed together.

[0010] Preferably, a fixed frame is fixedly connected to the top surface of the outer collection cylinder, and a drive motor is fixedly connected to the inner top wall of the fixed frame.

[0024] This invention provides a device suitable for collecting DNA samples from pond sediment under field conditions.

[0025] Please see Figure 1 The device includes a support box 1, on the bottom surface of which a fixing rod is fixedly installed. By inserting the fixing rod into the bottom mud, the entire device can be effectively fixed. A power supply is sealed inside the support box 1, which can supply power to the electrical equipment in this application.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The carrier box 1 is equipped with a collection mechanism 2, which includes a collection outer cylinder 201. The outer surface of the collection outer cylinder 201 is slidably connected to the carrier box 1. The carrier box 1 effectively limits the collection outer cylinder 201, making the collection outer cylinder 201 more stable when it moves up and down.

[0027] A transmission slide rod 202 is rotatably connected to the inner wall of the outer collection cylinder 201. A sealing plate 203 is fixedly connected to the outer surface of the transmission slide rod 202. A drive gear 204 is fixedly connected to one end of the transmission slide rod 202. A driven gear frame 205 is meshed with the outer surface of the drive gear 204. The bottom surface of the driven gear frame 205 is slidably connected to the outer collection cylinder 201. By driving the drive gear 204 to rotate, the sealing plate 203 can be driven to rotate around the transmission slide rod 202 as the axis, and the driven gear frame 205 can be driven to slide horizontally on the top surface of the outer collection cylinder 201 at the same time.

[0028] A pusher plate 206 is fixedly connected to the inner wall of the driven gear frame 205. The outer surface of the pusher plate 206 is slidably connected to the outer collection cylinder 201. By driving the driven gear frame 205 to move, the pusher plate 206 can be moved simultaneously, pushing the bottom mud between the outer collection cylinder 201 and the inner collection cylinder 207 into the inner collection cylinder 207 in layers.

[0029] The outer surface of the transmission slide rod 202 is slidably connected to the collection inner cylinder 207. The inner wall of the collection inner cylinder 207 is provided with a through groove that matches the sealing plate 203. According to the setting of the through groove, pulling the collection inner cylinder 207 downward can separate it from the transmission slide rod 202 and the sealing plate 203.

[0030] The top surface of the outer collecting cylinder 201 has a fixing hole. The top surface of the inner collecting cylinder 207 is fixedly connected to a threaded connecting rod 208 that matches the fixing hole on the top surface of the outer collecting cylinder 201. The outer surface of the threaded connecting rod 208 is threaded with a fixing nut 209. By inserting the threaded connecting rod 208 into the fixing hole on the top surface of the outer collecting cylinder 201, and then rotating the fixing nut 209 onto the surface of the threaded connecting rod 208, the outer collecting cylinder 201 and the inner collecting cylinder 207 can be effectively fixed together. Thus, when the outer collecting cylinder 201 is driven to move up and down, the inner collecting cylinder 207 can be driven to move up and down at the same time.

[0031] A fixed frame 210 is fixedly connected to the top surface of the outer cylinder 201. A drive motor 211 is fixedly connected to the inner top wall of the fixed frame 210. The output end of the drive motor 211 is fixedly connected to the drive gear 204. By turning on the drive motor 211, the drive gear 204 can be driven to rotate. The fixed frame 210 effectively supports and fixes the drive motor 211, making the drive motor 211 more stable during operation. A sealing ring is provided at the output end of the drive motor 211 to prevent water from entering the drive motor 211 and affecting its normal operation.

[0032] Please refer to it again. Figure 1A deep-reaching mechanism 3 is provided above the carrier box 1. The deep-reaching mechanism 3 includes a gantry frame 301. The bottom surface of the gantry frame 301 is fixedly connected to the carrier box 1. An electric push rod 302 is fixedly connected to the inner top wall of the gantry frame 301. The outer shell surface of the electric push rod 302 is fixedly connected to the carrier box 1. The telescopic end of the electric push rod 302 is fixedly connected to the outer collection cylinder 201. By opening the electric push rod 302, the outer collection cylinder 201 and the inner collection cylinder 207 can be driven to move downwards simultaneously.

[0033] The drive motor 211 and electric actuator 302 in this application are common electrical devices in the prior art. This application will not elaborate on their models or internal structures. They can also be replaced by other power sources.

[0034] In use, the device is first lowered to the bottom of the pond, with the fixing rod on the bottom of the support box 1 inserted into the bottom mud to secure the device. Then, the electric actuator 302 is activated to extend and drive the outer collection cylinder 201 and the inner collection cylinder 207 to move simultaneously into the bottom mud. During this descent, the bottom mud will remain in the gap between the two cylinders. Next, the drive motor 211 is activated to drive the drive gear 204 to rotate. The rotation of the drive gear 204 drives the transmission slide rod 202 to rotate, which in turn drives the sealing plate 203 to rotate around the transmission slide rod 202, effectively opening the feed inlet of the inner collection cylinder 207. Simultaneously, the rotation of the drive gear 204, through its own meshing force, drives the driven gear frame 205 to... The top surface of the outer collecting cylinder 201 slides horizontally. Simultaneously, the driven gear 205 slides, driving the pusher plate 206 towards the feed inlet of the inner collecting cylinder 207. The movement of the pusher plate 206 effectively pushes the bottom mud between the outer collecting cylinder 201 and the inner collecting cylinder 207 into the inner collecting cylinder 207 in layers. This effectively prevents the bottom mud from failing to enter the inner collecting cylinder 207 smoothly when it is hard, making the device more stable. When it is necessary to remove the bottom mud from the inner collecting cylinder 207, the fixing nut 209 is turned to disengage it from the threaded connecting rod 208, thereby releasing the fixing of the outer collecting cylinder 201 and the inner collecting cylinder 207. After release, the inner collecting cylinder 207 can be pulled out from the bottom of the outer collecting cylinder 201, making the device more practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
