Description

Technical Field

[0001] The utility model relates to the technical field of devices for water conservancy projects, in particular to an adjustable hydrological sediment collection device. Background Art

[0002] Sediment is the solid particles carried in natural water flows, mainly from the erosion of surface materials by water flows in the basin. The amount of sediment directly affects the future evolution trend of water sources and some possible consequences. Because the sediment content is directly related to the ecological environment of the water system, it has a great impact on the existence and possible development of future water sources. Therefore, we need to collect sediment in rivers to infer hydrological data.

[0003] Existing sediment collection devices, such as patent application number CN202123123875.5, entitled "A Hydrologically Adjustable Sediment Collection Device," disclose a hydrologically adjustable sediment collection device comprising a slotted tube body, a push mechanism at the top of the tube body, the end of which is fixedly connected to the top of the tube body, a discharge mechanism within the tube body, the end of which is slidably connected to the inner sidewall of the tube body, two sealing mechanisms at the bottom of the tube body, the ends of which are slidably connected to the bottom of the tube body, linkage mechanisms within the slots on both sides of the tube body, the ends of which are fixedly connected to the tops of the corresponding sealing mechanisms, and a reset mechanism at the top of the tube body. The device can push the collected sample out of the tube body without manual operation, avoiding tedious sample collection work and improving collection efficiency. The tube mouth can also be sealed to prevent sample leakage, ensuring sample quality and improving sampling quality.

[0004] However, when the above device is in use, the tube body is directly inserted into the mud and sand, and the push plate is moved by the mud and sand squeezing. During this process, there is an unstable connection between the tube body and the mud and sand, which may cause tilting or even tipping, and the mud and sand cannot be stably collected in the vertical direction, which has certain shortcomings.

[0005] Therefore, an adjustable hydrological sediment collection device is provided to solve the above-mentioned problems. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1:

[0029] Reference Figure 1-6 The adjustable hydrological sediment collection device includes a shell 1 and also includes: a mounting ring 2, which is sleeved on the shell 1, and an internal thread is provided in the mounting ring 2; a mounting thread 101, which is provided on the shell 1, and the mounting ring 2 can be fixed to the shell 1 by matching the mounting thread 101 and the internal thread; a plurality of groups of limiting pins 201, which are all slidably connected to the mounting ring 2; a spring member 202, which is sleeved on the limiting pin 201, and the two ends of the spring member 202 are respectively connected to the limiting pin 201 and the mounting ring 2, and the inner thread of the shell 1 is connected to the collection device. The collecting device includes a collecting shell 1 401 and a collecting shell 2 402. Both the collecting shell 1 401 and the collecting shell 2 402 are provided with a piercing head 404 for piercing mud and sand. The collecting shell 1 401 and the collecting shell 2 402 can be spliced into a complete hollow cylinder for storing mud and sand. The collecting shell 1 401 is fixedly connected to a rotating shaft 3, and the rotating shaft 3 may have a scale. One end of the rotating shaft 3 passes through the shell 1, and a connecting ring 203 is fixedly connected to the limiting pin 201. The connecting ring 203 is used for the synchronous movement of the limiting pin 201.

[0030] When using the device, a suitable river area is selected, and then the mounting ring 2 is mounted on the shell 1 through the mounting thread 101 by rotating. At this time, the limiting nail 201 will be longer than the bottom of the shell 1. Then, align it with the area of silt to be collected, hold the shell 1 with one hand, perpendicular to the horizontal plane, and move it toward the silt while pulling the connecting ring 203 upward with the other hand. At this time, the limiting nail 201, which is longer than the bottom of the shell 1 in the initial state, will move upward. At this time, the bottom of the shell 1 first contacts the silt, and then the connecting ring 203 can be loosened. Under the action of the spring member 202, the limiting nail 201 will penetrate into the silt, thereby fixing the position of the shell 1. After the required sediment is collected, the connecting ring 203 can be pulled upward to make the limiting pin 201 leave the sediment. At this time, the shell 1 can be easily separated from the sediment to complete the sampling. This process requires caution because there is no sealing device for the collection end of the collection device, and there is a possibility of sediment falling off. The specific sealing device can adopt the sealing plate in the existing device.

[0031] After the sampling is completed, the shell 1 can be leveled with the ground and the rotating shaft 3 can be rotated until the collection shell 1 401 and the collection shell 2 402 are both extended out of the shell 1. At this time, the collection shell 1 401 and the collection shell 2 402 can be separated to take out the mud and sand inside.

[0032] Example 2:

[0033] Reference Figure 1-6 The adjustable hydrological sediment collection device is basically the same as that of Example 1, and furthermore, a docking block 4011 and a docking groove 4021 are respectively provided on the collection shell 1 401 and the collection shell 2 402, and the docking block 4011 and the docking groove 4021 match each other.

[0034] By providing the docking block 4011 and the docking slot 4021 , the stability of the connection between the collection shell 1 401 and the collection shell 2 402 can be ensured.

[0035] Example 3:

[0036] Reference Figure 1-6 The adjustable hydrological sediment collection device is basically the same as that of Example 1, and furthermore, an air vent 403 is provided on the collection shell 401.

[0037] Through the setting of the air vent 403, when mud and sand enter, the gas inside the collection shell 1 401 and the collection shell 2 402 can be discharged, avoiding the presence of gas affecting the entry of mud and sand into the collection shell 1 401 and the collection shell 2 402, thereby facilitating the collection of mud and sand.

[0038] The utility model is provided with the limiting nail 201. When in use, the housing can be fixed by fixing the mounting ring through the mounting thread 101, and the mud and sand can be collected vertically through the collection device, which is easy to use.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
