Description

Technical Field

[0001] This utility model relates to the field of silt thickness detection technology, and in particular to a silt thickness detection mechanism. Background Technology

[0002] In water conservancy projects, regular monitoring of river silt is a crucial step in maintaining river health and ensuring flood control and drainage capabilities. Staff need to periodically monitor the thickness of the silt in the river to develop corresponding cleaning and maintenance plans based on the actual situation.

[0003] Chinese Patent 202421892387.1 relates to the field of river channel detection technology and discloses a river channel silt thickness detection mechanism, including a base. A placement shell is fixedly connected to the top of the base. A rotating rod is rotatably connected through the inner wall of the placement shell. A collecting roller is fixedly connected to the outer wall of the rotating rod. A rope is wound around the outer wall of the collecting roller. A limiting component is provided on the outer wall of the rotating rod. A lifting component is provided at the top of the base, including an electric push rod fixedly connected to the top of the base. Moving wheels are provided at the four corners of the bottom of the base. In this invention, the limiting component allows for easy rope release by simply pulling the handle outwards and then rotating it, and rope collection by simply rotating the handle to rotate the rotating rod. Furthermore, the trapezoidal block design enables unidirectional limiting, making rope collection more convenient.

[0004] However, the aforementioned silt thickness detection mechanisms often have excessively long limiting shells. These excessively long limiting shells not only make the overall size of the detection mechanism bulky and difficult to adapt to the storage requirements of small spaces, but also increase additional costs and risks during handling and transportation. In particular, excessive space occupation in warehouse management and equipment scheduling undoubtedly reduces space utilization and affects the storage and retrieval efficiency of other equipment. Therefore, a silt thickness detection mechanism is proposed to solve the above problems. Utility Model Content

[0006] To address the technical problems existing in the background art, this utility model proposes a silt thickness detection mechanism. By folding the first support rod, the state in which the first support rod and the second support rod abut from the end face is changed to the state in which the first support rod and the side of the second support rod are in contact. This significantly shortens the overall length in the non-working state and improves portability and spatial adaptability.

[0008] This utility model provides a silt thickness detection mechanism, including a base plate, a movable component installed on the upper end of the base plate, a movable plate installed on the movable end of the movable component, and the top of the movable plate connected to a second support rod via an electric push rod.

[0009] It includes a first support rod, one end of which is hinged to a second support rod, and the other end of which is connected to a second mounting plate. A rotating assembly is installed at the connection between the second support rod and the first support rod.

[0010] A first motor is installed on the inner wall of the second mounting plate. The output shaft of the first motor passes through the side wall of the second mounting plate connected to it and is connected to the first mounting plate. A detection component is installed on the first mounting plate.

[0011] The bottom of the base plate is equipped with multiple spaced casters.

[0012] Preferably, the moving component includes a threaded rod, a moving housing, a moving block, a connecting block, a sliding slot, and a third motor. The moving housing is horizontally mounted on the upper end of the base plate. The threaded rod is horizontally arranged and rotatably connected to the inner wall of the moving housing. The sliding slot passes through the upper end face of the moving housing. The third motor is located on the side of the moving housing. The output shaft of the third motor passes through the side wall of the moving housing and is coaxially connected to the threaded rod. The connecting block is located inside the sliding slot. One end of the connecting block is connected to the moving plate, and the other end of the connecting block is connected to the moving block. The threaded rod is threaded through the middle of the moving block.

[0013] Preferably, the rotating assembly includes a fixed plate, a grooved plate, and a second motor. The second motor is located at the bottom of the connection between the first support rod and the second support rod. The grooved plate is fixed to the second support rod and abuts against the first support rod. The second motor is located on the side of the grooved plate. The fixed plate is fixed to the side of the first support rod. The output shaft of the second motor passes through the mounting sidewall of the grooved plate and is connected to the fixed plate.

[0018] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0019] When the silt thickness detection mechanism needs to be folded for storage, the first motor drives the first mounting plate to rotate 180°, and then the rotating component drives the first support rod to rotate 180° clockwise. This changes the state in which the first support rod and the second support rod abut from their end faces to the state in which the first support rod and the side of the second support rod are in contact. This significantly shortens the overall length in the non-working state and improves portability and space adaptability. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1-5 As shown, the present invention proposes a silt thickness detection mechanism, including a base plate 25, a movable component installed on the upper end of the base plate 25, a movable plate 16 installed on the movable end of the movable component, and the top of the movable plate 16 connected to the second support rod 12 through an electric push rod 11.

[0030] It includes a first support rod 7, one end of which is hinged to a second support rod 12, and the other end of which is connected to a second mounting plate 3. A rotating component is installed at the connection between the second support rod 12 and the first support rod 7.

[0031] A first motor 6 is installed on the inner wall of the second mounting plate 3. The output shaft of the first motor 6 passes through the side wall of the second mounting plate 3 connected to it and is connected to the first mounting plate 2. A detection component is installed on the first mounting plate 2.

[0032] The bottom of the base plate 25 is equipped with multiple spaced casters 20.

[0033] In this invention, during use, multiple casters 20 first move the base plate 25 to the location where the silt thickness needs to be measured. Then, a rotating assembly drives the first support rod 7 to rotate 180° counterclockwise, and the first motor 6 drives the first mounting plate 2 to rotate 180°, so that the detection end of the detection component faces downward. Finally, by retracting the electric push rod 11, the detection end of the detection component is immersed in the water to a depth of 5-10cm, thereby enabling the detection of silt thickness. Furthermore, the moving assembly moves the moving plate 16 accordingly. When the moving plate 16 moves, the detection component is moved along with the electric push rod 11, the second support rod 12, the first support rod 7, the second mounting plate 3, the first motor 6, and the first mounting plate 2. This improves the rapid positioning of the detection component, shortens the time required for a single detection, and appropriately increases the distance between the detection component and the riverbank.

[0034] When folding for storage is required, the first motor 6 drives the first mounting plate 2 to rotate 180°, and then the rotating component drives the first support rod 7 to rotate 180° clockwise, so that the first support rod 7 contacts the outer end face of the second support rod 12, which significantly shortens the overall length in the non-working state and greatly improves portability and space adaptability; then, the moving component cooperates with the electric push rod 11 to further reduce the overall length.

[0035] In an optional embodiment, the moving assembly includes a threaded rod 23, a moving housing 19, a moving block 22, a connecting block 21, a sliding slot 13, and a third motor 14. The moving housing 19 is horizontally mounted on the upper end of the base plate 25. The threaded rod 23 is horizontally arranged and rotatably connected to the inner wall of the moving housing 19. The sliding slot 13 passes through the upper end face of the moving housing 19. The third motor 14 is located on the side of the moving housing 19. The output shaft of the third motor 14 passes through the side wall of the moving housing 19 and is coaxially connected to the threaded rod 23. The connecting block 21 is located inside the sliding slot 13. One end of the connecting block 21 is connected to the moving plate 16, and the other end of the connecting block 21 is connected to the moving block 22. The threaded rod 23 is threaded through the middle of the moving block 22.

[0036] It should be noted that when the third motor 14 is started, the third motor 14 can drive the threaded rod 23 to rotate. When the threaded rod 23 rotates, it can drive the moving block 22 to move along the threaded rod 23. When the moving block 22 moves, it can drive the moving plate 16 to move through the connecting block 21, thereby driving the electric push rod 11 to move accordingly. Furthermore, the connecting block 21 will move within the sliding slot 13, ensuring the stability of the movement of the moving plate 16.

[0037] In an optional embodiment, the rotating assembly includes a fixed plate 8, a grooved plate 9, and a second motor 10. The second motor 10 is located at the bottom of the connection between the first support rod 7 and the second support rod 12. The grooved plate 9 is fixed to the second support rod 12 and abuts against the first support rod 7. The second motor 10 is located on the side of the grooved plate 9. The fixed plate 8 is fixed to the side of the first support rod 7. The output shaft of the second motor 10 passes through the mounting sidewall of the grooved plate 9 and is connected to the fixed plate 8.

[0038] It should be noted that when in use, starting the second motor 10 can drive the fixed plate 8 connected to it to rotate, and the fixed plate 8 in turn drives the first support rod 7 to rotate.

[0039] When it is necessary to test the thickness of the first support rod 7 for silt, the first support rod 7 will abut against the inner bottom wall of the groove plate 9, ensuring the stability of the installation of the first support rod 7.

[0040] In an optional embodiment, the output shaft of the second motor 10 is coaxial with the hinge joint between the first support rod 7 and the second support rod 12.

[0041] It should be noted that when the first support rod 7 is rotated, it is ensured that the first support rod 7 can rotate at the hinge point connected to the second support rod 12.

[0042] In an optional embodiment, the detection assembly includes an ultrasonic mud level detector 1, a connecting pipe 4, a detection probe 5, and a connecting wire 24. The bottom of the first mounting plate 2 is connected to the detection probe 5 through the connecting pipe 4. The ultrasonic mud level detector 1 is mounted on the upper surface of the first mounting plate 2. The connecting wire 24 passes through the inside of the connecting pipe 4. One end of the connecting wire 24 is connected to the detection probe 5, and the other end of the connecting wire 24 is connected to the ultrasonic mud level detector 1.

[0043] It should be noted that during use, the electric push rod 11 is retracted so that the detection probe 5 can be completely submerged in water, and the installation height is 5-10cm above the water surface;

[0044] The detection probe 5 can be connected to the ultrasonic mud level detector 1 using the connecting cable 24 to ensure stable signal transmission under physical protection of the line.

[0045] When in use, the detection probe 5 emits ultrasonic pulses downwards. When it encounters the interface between the silt layer and the water layer, it reflects the echo. The ultrasonic mud level detector 1 calculates the thickness of the silt by calculating the time difference between the emitted and received echoes and combining it with the sound velocity formula (formula: thickness = sound velocity × time difference / 2).

[0046] The software automatically analyzes multi-layer echo signals, distinguishes between transition layers and stable silt layers, and outputs silt level data.

[0047] In an optional embodiment, a counterweight 15 is included, which is symmetrically distributed and mounted on the upper end of the base plate 25 away from the detection component.

[0048] It should be noted that the symmetrically distributed counterweights 15 prevent tipping when measuring the thickness of the silt.

[0049] In an optional embodiment, the base plate 25 includes a controller support shaft 17 and a controller 18, with the upper end of the base plate 25 connected to the controller 18 via the controller support shaft 17.

[0050] It should be noted that the controller support shaft 17 can provide stable support for the controller 18; and the controller 18 can control the third motor 14, the second motor 10, the first motor 6 and the electric push rod 11 respectively. The mud level data detected by the ultrasonic mud level detector 1 can be transmitted to the display screen of the controller 18 for display via its built-in wireless signal unit.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
