Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to a riverbed sediment sample collector. Background Art

[0002] In river management, collecting riverbed sediment can be used to detect the accumulation and distribution of water pollutants in the sediment, so as to understand the river pollution situation, so as to formulate corresponding river management plans and prevent river pollutants from damaging the ecological environment. During the collection process, due to the deep depth of the river, the collection device is often tied with a rope and sunk to the bottom of the river for collection. Some electric collection devices will inevitably have water ingress at the bottom of the river. At the same time, for the sake of convenience and practicality, the use of electric collection devices is avoided.

[0003] Existing technologies, such as the Chinese utility model patent with publication number CN202122543809, disclose "a portable and detachable sediment sampling and separation device". After the collection device is sunk to the riverbed, a spring pushes the piston to move after turning on the switch, so that the collection device uses pressure to suck sediment and river water into the collection device; however, this structure has a defect, that is, when sucking sediment, the elastic force of the spring may cause the collection device to jump, thereby causing the collection port to detach from the riverbed. At the same time, since its suction port is in an open state, sediment may spill from the suction port during the ascent process.

[0004] Therefore, in order to solve the above technical problems, the utility model provides a riverbed sediment sample collector. Utility Model Content

[0010] Furthermore, the collecting tube includes a push plate arranged at the top, the outer diameter of the push plate is larger than the outer diameter of the sealing tube, a sliding groove is opened at the top of the collecting tube, a collecting chamber is opened below the collecting tube, multiple collecting grooves are opened vertically on the outside of the collecting chamber, and a scraper is arranged on the outside of the collecting groove.

[0011] Furthermore, the connecting rod includes a clamping block provided at both ends and respectively connected to the baffle plate and the push plate in a sliding manner, and the cross section of the clamping block is a "concave" structure.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] See Figures 1 to 9 As shown, a riverbed sediment sample collector is characterized in that it includes a shell 1, a hollow chuck 12, a support plate 13, a sealing cylinder 15, a bearing 14 arranged in the middle of the support plate 13, and a counterweight 16 arranged below the outer surface of the shell 1, which are respectively arranged inside the shell 1 from top to bottom; a collecting mechanism 2 is arranged through the shell 1; the collecting mechanism 2 includes a pull rod 21 that slides through the limit column 11 and the hollow chuck 12, a tower-shaped spring 22 with two ends fixedly mounted on the chuck 12 and the pull rod 21, a transmission shaft 23 fixedly mounted in the bearing 14, and the transmission shaft 23 is slidably connected to the pull rod 21, a collecting tube 24 that is slidably connected to the transmission shaft 23 and the sealing cylinder 15 inside and outside, a first spring 25 with two ends fixedly mounted on the transmission shaft 23 and the collecting tube 24, a plurality of connecting rods 26 that slide through the support plate 13, and the two ends of the connecting rod 26 are slidably connected to the pull rod 21 and the collecting tube 24 respectively; a safety component 27 is provided at the middle of the spring 22 on one side of the shell 1.

[0031] A plurality of limiting posts 11 are provided at the top of the housing 1 and are spaced apart in an annular pattern. The limiting posts 11 are spaced apart in an annular pattern and can limit the rotation of the pull rod 21 after being engaged with the splines 211 on the pull rod 21 .

[0032] The pull rod 21 includes a spline 211 disposed in the middle and engaging with a plurality of limiting posts 11, a baffle 212 disposed below the spline 211, and a rectangular post 213 disposed below the baffle 212. The spline 211 engaging with the limiting posts 11 allows the pull rod 21 to be pulled and, after engaging with the fixed limiting posts 11 via the spline 211, to limit the rotation of the pull rod 21, thereby limiting the rotation of the spring 22. Furthermore, the baffle 212 positioned behind the spring 22 further stabilizes the spring 22.

[0033] The transmission shaft 23 includes a retaining ring 231 disposed in the middle, a connecting groove 232 disposed at the top of the transmission shaft 23 that engages with the rectangular column 213, and a rectangular connecting shaft 233 disposed at the bottom. The transmission shaft 23 is fixed by the bearing 14 so that the transmission shaft 23 can only rotate. The connection between the connecting groove 232 and the rectangular column 213 allows the pull rod 21 to slide up and down while the transmission shaft 23 can also be driven by the pull rod 21 to rotate.

[0034] The collection tube 24 includes a push plate 241 disposed at the top, the outer diameter of which is larger than that of the sealing tube 15. It also includes a sliding groove 242 disposed at the top of the collection tube 24, a collection chamber 243 disposed below the collection tube 24, a plurality of collection grooves 244 disposed vertically outside the collection chamber 243, and a scraper 245 disposed outside the collection grooves 244. The push plate 241 is fixedly connected to a first spring 25, the other end of which is connected to a fixed retaining ring 231. This allows the first spring 25 to provide thrust to the collection tube 24 via the push plate 241. Simultaneously, the push plate 241 is restrained by the sealing tube 15, preventing the collection tube 24 from detaching.

[0035] The connecting rod 26 includes a clamping block 261 at each end, which is slidably connected to the baffle 212 and the push plate 241. The clamping block 261 has a concave structure. The concave structure of the clamping block 261 can drive the push plate 241 to move up and down through the baffle 212, while the rotation of the push plate 241 will not affect the connecting rod 26.

[0036] The fuse assembly 27 includes a fuse box 271 disposed through one side of the upper portion of the housing 1. A slot 272 is vertically formed through the fuse box 271, and the slot 272 is located outside the housing 1. A positioning slot 273 is formed on one side of the fuse box 271, which communicates with the interior of the housing 1. A wedge-shaped stopper 274 is slidably mounted within the fuse box 271. The flat end of the stopper 274 is provided with a protrusion that slides into the positioning slot 273. Two second springs 275 are fixedly connected to the flat end of the stopper 274 and the inner wall of the fuse box 271. The slot 272 is penetrated by a matching safety pin 276. One inclined end of the wedge-shaped stopper 274 faces the outside of the housing 1 and is tilted upward. When the safety pin 276 is inserted, it can push the stopper 274 to move, causing the protrusion to extend and clamp the baffle 212, preventing the baffle 212 from falling. The second spring 275 also pushes the stopper 274 back into place after the safety pin 276 is removed.

[0037] Example 2

[0038] The outer diameter of the first spring 25 of the present invention is smaller than the outer diameters of the push plate 241 and the retaining ring 231 , and the inner diameter of the first spring 25 is larger than the inner diameter of the retaining ring 231 ;

[0039] The principle of the power storage of the spring 22 of the present invention is based on the power storage of a mechanical watch. The power storage spring 22 drives the pull rod 21 to rotate.

[0040] The bottom of the collecting tube 24 of the present invention is conical, and the collecting tube 24 is located below the bottom surface of the counterweight 16, which enables the collecting tube 24 to collect sediments at the bottom of the river more deeply by rotating during collection;

[0041] The bottom of the limit post 11 and the top of the spline 211 of the present invention are triangular structures, so that the limit post 11 and the spline 211 will not get stuck when connected;

[0042] The bottom of the scraper 245 of the present invention is an inclined surface, and after the collection tube 24 is received in the collection tube 24, the scraper 245 can fit with the collection tube 24 through elastic potential energy;

[0043] The conical portion at the bottom of the collection tube 24 of the present invention is threadedly connected to the collection tube 24, and the connection direction is the same as the collection direction, so that the conical portion becomes tighter as the collection tube 24 rotates;

[0044] The pull rod 21 and the safety pin 276 of the present invention are respectively connected with different ropes.

[0045] Example 3

[0046] The working principle is as follows: before collecting riverbed sediment, the user first rotates the pull rod 21, and the rotating pull rod 21 drives the spring 22 to rotate. Then, the pull rod 21 is lifted upward. When the pull rod 21 is lifted upward, the tower-shaped spring 22 is compressed. At the same time, the baffle 212 also moves upward to press the spring 22, making the spring 22 more stable. The spline 211 provided on the rising pull rod 21 cooperates with the limit column 11 to prevent the pull rod 21 from rotating under the drive of the spring 22; the baffle 212 synchronously drives the push plate 241 to rise through the connecting rod 26, and the push plate 241 drives the collecting tube 24 to move upward and retract into the sealing tube 15; the user then inserts the safety pin 276 into the safety box 271 through the slot 272, and the safety pin 276 pushes the wedge-shaped stopper 274 to move to one side. The protrusion at one end of the stopper 274 moves along the positioning groove 273 to the inside of the shell to the bottom of the baffle 212, thereby limiting the downward movement of the baffle 212;

[0047] After preparation, the user sinks the device into the water through the rope on the pull rod 21. The counterweight 16 makes the device sink to the bottom faster and more stable, and can better cope with water flow. After pulling the rope on the pull rod 21 and confirming that the device has sunk to the bottom, the user loosens the rope of the pull rod 21 and pulls out the safety pin 276 by pulling the rope on the safety pin 276. After the safety pin 276 is pulled out, the push block is pushed back to its original position under the action of the second spring 275, thereby releasing the restriction on the baffle 212. The baffle 212 moves downward by gravity and the elastic force of the clockwork spring 22, and the first spring 25 pushes the push plate 241 downward, and the push plate 241 also pulls the baffle 212 downward through the connecting rod 26. The downward movement of the baffle 212 The movable pull rod 21 moves downward, and the downward movement of the pull rod 21 drives the spline 211 to disengage from the limit column 11, so that the restriction of the spring spring 22 is released, and the spring spring 22 drives the pull rod 21 to rotate; after the pull rod 21 rotates, it drives the transmission shaft 23 to rotate through the rectangular column 213, and the transmission shaft 23 drives the collection tube 24 to rotate through the connecting shaft 233. Because the collection tube 24 is pushed by the first spring 25 to pop out and insert into the riverbed sediment, and during the rotation of the collection tube 24, the conical structure at the bottom of the collection tube 24 can break the soil, and then continue to collect downward under the push of the first spring 25, thereby increasing the collection depth of the collection tube 24, and the scraper 245 on the collection tube 24 sends the sediment into the collection chamber 243 through the collection groove 244 when rotating;

[0048] After the collection is completed, the rope is pulled by the operator, and then the pull rod 21 moves upward. After the pull rod 21 moves, it drives the spring spring 22 to contract. At the same time, the baffle 212 also drives the push plate 241 to contract through the connecting rod 26, and then the push plate 241 drives the collection tube 24 to retract into the sealing tube 15, so that the collected material will not spill out during the recovery process.
