Abstract
Description
Technical Field
[0001] This utility model relates to the field of river monitoring technology, and in particular to a riverbed siltation detection device. Background Technology
[0002] River silt depth detection is an important hydraulic engineering technology used to measure the depth and distribution of silt in river channels, so that timely dredging measures can be taken to ensure the smooth flow of waterways and the effective utilization of water resources.
[0003] Traditional siltation measuring rods may have the silt washed away by water flow when lifted, making it impossible to accurately read the silt depth based on the silt marks. Furthermore, when the rod is inserted into the silt, it pushes the silt outwards; if the silt has poor fluidity, this can lead to a thicker silt layer at the rod, further affecting the accuracy of the results. Therefore, an improved riverbed siltation measuring device is proposed. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to provide a riverbed siltation detection device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, one embodiment of the present invention provides a riverbed siltation detection device, including a detection rod, a receiving cavity being provided inside the detection rod, a pointed cone being provided at the bottom end of the detection rod, a top plate being fixedly connected to the top end of the detection rod, and a handle being fixedly connected to the side of the top plate;
[0007] Several horizontal plates are fixedly connected to the inner wall of the receiving cavity. The detection rod has a mud outlet hole at the horizontal plate. An observation component is provided on the other side of the detection rod. A scale is provided on one side of the observation component. A sealing component is provided at the bottom of the detection rod. A horizontal bubble meter is provided on the upper part of the top plate.
[0008] Preferably, in any of the above embodiments, the detection rod has a cylindrical structure, and a hanging ring is fixedly connected to the top end of the detection rod.
[0009] Preferably, in any of the above embodiments, the receiving cavity has a cylindrical structure, and the outer side of the pointed cone is provided with threads.
[0010] The above technical solution employs a detection rod as the main body of the detection device, providing an installation platform for related monitoring components. During use, the detection rod is inserted into the silt until the bottom of its pointed tip contacts the riverbed. The thickness of the silt is then measured using the rod itself. A hanging ring is provided at the end of the detection rod for easy storage by hanging it on a foundation when not in use. A receiving cavity allows silt to enter. The pointed tip at the bottom of the detection rod, due to its small base area, reduces resistance when in contact with the silt, facilitating insertion of the detection rod.
[0011] Preferably, in any of the above embodiments, the handle is fitted with an anti-slip sleeve, and several of the horizontal plates are evenly arranged along the height direction of the detection rod.
[0012] Preferably, in any of the above embodiments, the sealing assembly is a sealing sleeve threadedly connected to the outside of the pointed cone, and the observation assembly is an observation window.
[0013] The above technical solution employs the following: A top plate is installed at the top of the detection rod, providing a mounting platform for the handle and level bubble level. The handle is designed for easy gripping by operators. An anti-slip sleeve is installed on the outside of the handle to improve stability during handling. A horizontal plate is installed inside the receiving cavity, providing a platform for silt retention, allowing the silt to be pulled out of the river along with the detection rod. An observation component is used to observe the silt retention within the detection rod from the outside. A scale is installed on the side of the observation component, allowing direct determination of silt thickness during observation.
[0014] Preferably, in any of the above solutions, the horizontal plate adopts a downwardly concave arc-shaped structure, and the height of the observation component is not less than the distance between the bottom horizontal plate and the top horizontal plate.
[0015] Preferably, in any of the above embodiments, the sealing component is a sealing plug inserted into the pointed cone, and the observation component is an observation hole provided through the detection rod.
[0016] The above technical solution employs a downward-concave arc-shaped structure for the horizontal plate, which helps retain sludge within the containment cavity and reduces the impact of water washing during the lifting of the detection rod. A sealing component is installed at the bottom of the detection rod to seal the containment cavity when not in use, preventing foreign objects from entering. A horizontal bubble level is installed on the top plate to assist operators in maintaining the detection rod in a vertical position. By controlling the height of the observation component, operators can directly observe the situation within the detectable range from the outside, ensuring effective observation.
[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0018] 1. This riverbed siltation detection device comprises a receiving cavity, a conical section, horizontal plates, a mud discharge hole, an observation component, and a scale. In use, the handle is held, and the detection rod is inserted into the silt until the bottom of the conical section contacts the riverbed. During this process, the conical section squeezes the silt to both sides, assisting the detection rod in moving downwards, allowing the silt to enter the receiving cavity. The level bubble meter is used to keep the detection rod vertical, and the handle is pulled upwards to remove the rod. Some silt slides out of the receiving cavity, while some remains on the horizontal plates. The silt is observed on the horizontal plates through the observation component, and the silt thickness is read using the scale. Even under the influence of water flow, some silt remains within the detection rod, effectively improving detection accuracy. The overall ring-shaped structure of the detection device minimizes the squeezing effect on the silt, resulting in less variation in silt thickness and higher detection accuracy.
[0019] 2. This riverbed siltation detection device features a hanging ring at the end of the detection rod for easy storage by hanging it on a relevant foundation when not in use. A pointed cone at the bottom of the rod reduces resistance when in contact with silt due to its small surface area, facilitating insertion. An anti-slip sleeve on the outside of the handle improves stability during handling. The horizontal plate has a downward-concave arc structure, which helps retain silt within the containment cavity and reduces the impact of water flow washing during rod lifting. A level bubble level is installed on the top plate to assist operators in maintaining the rod in a vertical position.

[0029] like Figures 1-4 As shown, this utility model includes a detection rod 1, a receiving cavity 2 is provided inside the detection rod 1, a pointed cone 3 is provided at the bottom end of the detection rod 1, a top plate 4 is fixedly connected to the top end of the detection rod 1, and a handle 5 is fixedly connected to the side of the top plate 4.
[0030] Several horizontal plates 6 are fixedly connected to the inner wall of the receiving cavity 2. The detection rod 1 has a mud outlet hole 7 at the horizontal plate 6. An observation component 8 is provided on the other side of the detection rod 1. A scale mark 9 is provided on one side of the observation component 8. A sealing component 10 is provided at the bottom of the detection rod 1. A horizontal bubble meter 11 is provided on the upper part of the top plate 4.
[0031] Example 1: The detection rod 1 has a cylindrical structure, with a hanging ring fixedly connected to its top. The receiving cavity 2 also has a cylindrical structure, with threads on the outer side of the pointed cone 3. The detection rod 1 serves as the main body of the detection device, providing an installation platform for related monitoring components. In use, the detection rod 1 is inserted into the silt until the bottom of the pointed cone 3 contacts the riverbed. The thickness of the silt is measured using the rod body. A hanging ring is provided at the end of the detection rod 1 for easy storage by hanging it on a relevant foundation when not in use. The receiving cavity 2 allows silt to enter. The pointed cone 3 at the bottom of the detection rod 1, due to its small bottom surface area, reduces resistance when in contact with the silt, making it easier to insert the detection rod 1 into the silt.
[0032] Example 2: A non-slip sleeve is fitted onto the handle 5, and several horizontal plates 6 are evenly arranged along the height direction of the detection rod 1. The sealing assembly 10 is threadedly connected to the sealing sleeve on the outside of the pointed cone 3, and the observation assembly 8 uses an observation window. A top plate 4 is provided at the top of the detection rod 1, which provides an installation platform for the handle 5 and the level bubble meter 11. The handle 5 is designed for easy gripping by the operator. A non-slip sleeve is provided on the outside of the handle 4 to improve stability during gripping. Horizontal plates 6 are provided inside the receiving cavity 2, which provide a retention platform for silt, allowing the silt to be pulled out of the river along with the detection rod 1. The observation assembly 8 is used to observe the silt retention inside the detection rod 1 from the outside. A scale 9 is provided on the side of the observation assembly 8, allowing the silt thickness to be determined directly from the scale 9 during observation.
[0033] Example 3: The horizontal plate 6 adopts a downwardly concave arc-shaped structure, and the height of the observation component 8 is not less than the distance between the bottom and top horizontal plates 6. The sealing component 10 adopts a sealing plug inserted into the pointed cone 3, and the observation component 8 adopts an observation hole that penetrates the detection rod 1. The downwardly concave arc-shaped structure of the horizontal plate 6 helps to retain sludge in the receiving cavity 2 and reduces the impact of water washing during the lifting of the detection rod 1.

A horizontal bubble meter 11 is set on the top plate 4 to help the operator keep the detection rod 1 in a vertical position. By controlling the height of the observation component 8, the operator can directly observe the situation within the detectable range from the outside, ensuring the observation effect.
[0034] The working principle of this utility model is as follows:
[0035] S1. Holding the handle 5, insert the detection rod 1 into the silt until the bottom of the cone 3 contacts the riverbed. During this process, the cone 3 squeezes the silt to both sides, assisting the detection rod 1 to move downwards, and the silt enters the receiving cavity 2;
[0036] S2. Observe the horizontal bubble meter 11. Keep the detection rod 1 vertical and pull the handle 5 upward to lift the detection rod 1 out. Some of the sludge in the receiving cavity 2 slides out, while some of the sludge remains on each horizontal plate 6.
[0037] S3. Observe the silt on the horizontal plate 6 at the observation component 8, and read the silt thickness with the help of the scale 9.
[0038] Compared with the prior art, the present invention has the following advantages:
[0039] 1. This riverbed siltation detection device comprises a receiving cavity 2, a conical section 3, horizontal plates 6, a mud outlet 7, an observation component 8, and a scale 9. In use, the handle 5 is held to insert the detection rod 1 into the silt until the bottom of the conical section 3 contacts the riverbed. During this process, the conical section 3 squeezes the silt to both sides, assisting the detection rod 1 in moving downwards, allowing the silt to enter the receiving cavity 2. The horizontal bubble meter 11 is used to keep the detection rod 1 vertical, and the handle 5 is pulled upwards to remove the detection rod 1. Some silt slides out of the receiving cavity 2, while some remains on the horizontal plates 6. The silt on the horizontal plates 6 is observed through the observation component 8, and the silt thickness is read using the scale 9. Even under the influence of water flow, some silt remains in the detection rod 1, effectively improving detection accuracy. The overall ring structure of the detection device minimizes the squeezing effect on the silt, resulting in less variation in silt thickness and higher detection accuracy.
[0040] 2. This riverbed siltation detection device features a hanging ring at the end of the detection rod 1 for easy storage by hanging it on a relevant foundation when not in use.
