AI Technical Summary
Existing river silt depth detection devices occupy a large space and are inconvenient to transport when the detection depth is large, and the detection rod is prone to tilting, resulting in large measurement errors.
A device was designed that includes a handheld rod, a chassis, a measuring rod, a limiting hook, a sliding rod, and a gravity hammer. The locking and releasing of the measuring rod is controlled by the engagement and disengagement of the limiting hook and the limiting groove. Combined with the elastic force of the energy storage spring and the impact spring, the measuring rod is ensured to be inserted vertically into the silt layer. The penetration force is enhanced by the multiple impacts of the gravity hammer.
It achieves the shortening and storage of the measuring rod, making it easy to carry and transport, ensuring the verticality of the measurement, reducing detection errors, and improving measurement accuracy and efficiency.

[0027] Embodiment 1
[0028] Referring to Figures 1 to 5 The utility model provides a kind of river sludge depth detection device, including hand pole 1, the lower end of hand pole 1 is fixedly arranged chassis 2, hand pole 1 is slidably arranged measuring rod 3 in;
[0029] The diameter of chassis 2 is larger, when chassis 2 contacts sludge surface, can form stable plane datum, ensure that measuring rod 3 keeps vertical state, avoid artificial deviation of placement, and the inclination of measuring rod caused by water flow, improve measurement accuracy;
[0030] The top of measuring rod 3 is fixedly arranged force spring 4, one end of force spring 4 is fixedly connected with measuring rod 3, and the other end is in contact with the top of hand pole 1;
[0031] Two limit hooks 5 are rotatably arranged on the rod body of hand pole 1, and a limit slot 6 is formed in the rod body of measuring rod 3, and the limit hook 5 is clamped with the limit slot 6.
[0032] The upper end of measuring rod 3 is sleeved with sliding rod 7, and the two ends of sliding rod 7 are fixedly connected with measuring rod 3 through mounting bracket, and gravity hammer 8 is slidably arranged on the rod body of sliding rod 7.
[0033] The user holds the hand-held rod 1, and vertically places the base plate 2 on the surface of the silt to be measured. The base plate 2 sinks to contact the silt due to its own weight. After the base plate 2 contacts the silt, the operator controls the limiting hook 5 to rotate, so that it is disengaged from the limiting slot 6 on the measuring rod 3. After the limiting hook 5 is unlocked, the measuring rod 3 slides downward rapidly under the elastic force of the force storage spring 4, extends from the hand-held rod 1 and inserts into the silt.
[0034] At the same time, the gravity hammer 8 on the sliding rod 7 converts the gravitational potential energy into impact kinetic energy when it freely falls, and cooperates with the force storage spring 4 to enhance the penetration of the measuring rod 3 into the silt layer, so that the measuring rod 3 rapidly penetrates the silt layer, and the measurement efficiency is significantly improved.
[0035] The locking and release of the measuring rod 3 are controlled by the engagement and disengagement of the limiting hook 5 and the limiting slot 6, without the need for electricity or complex sensors, and it is suitable for use in a power-free environment.
[0036] The base plate 2 is also slidably provided with a pressing plate 9. A plurality of slide columns 10 are fixedly arranged on the plate body of the pressing plate 9. The pressing plate 9 is slidably connected to the base plate 2 through the slide columns 10.
[0037] The upper ends of the two opposite slide columns 10 are respectively fixedly provided with a trigger lever 11. The trigger lever 11 is slidably connected to the hand-held rod 1.
[0038] The limiting hook 5 is also fixedly provided with an abutting plate 12. When the trigger lever 11 abuts against the abutting plate 12, the trigger lever 11 pushes the limiting hook 5 to rotate through the abutting plate 12.
[0039] When the base plate 2 contacts the surface of the silt, the silt generates an upward reaction force on the pressing plate 9, which pushes the pressing plate 9 to slide upward along the slide columns 10.
[0040] When the pressing plate 9 rises, the two trigger levers 11 fixed to the upper ends of the opposite slide columns 10 move upward synchronously. After the top end of the trigger lever 11 contacts the abutting plate 12 on the limiting hook 5, the trigger lever 11 continuously pushes the abutting plate 12, so that the limiting hook 5 rotates around the rotating shaft in a direction away from the limiting slot 6 of the measuring rod 3. When the limiting hook 5 completely disengages from the limiting slot 6 of the measuring rod 3, the measuring rod 3 is released instantaneously under the action of the force storage spring 4, and inserts downward into the silt.
[0041] A reset spring 13 is sleeved on each slide column 10. The two ends of the reset spring 13 are respectively fixedly connected to the pressing plate 9 and the base plate 2.
[0042] Under the action of the reset spring 13, the pressing plate 9 is always located below the base plate 2. The pressing plate 9 first contacts the surface of the silt. When the base plate 2 contacts the silt, the pressing plate 9 can move upward. Under the action of the trigger lever 11, the pressing plate 9 pushes the limiting hook 5 to rotate, so that it disengages from the limiting slot 6, thereby realizing the automatic release of the measuring rod 3.
[0043] The gravity hammer 8 is fixed with an impact spring 14 at each end.
[0044] When the gravity hammer 8 falls to the bottom, the lower end impact spring 14 is compressed, and part of the impact kinetic energy is converted into elastic potential energy, which is released at the moment of bottoming, superimposed with the inertia of the gravity hammer 8, forming a secondary impact, further increasing the penetration depth of the measuring rod 3 into the silt layer.
[0045] When the gravity hammer 8 moves upward under the action of the lower end spring, the upper end spring of the gravity hammer 8 is compressed, and when the upper end spring releases the elastic force, it pushes the gravity hammer 8 to move downward, and the gravity hammer 8 repeatedly slides in the measuring rod 3, forming multiple impacts under the action of the impact spring 14 and the inertia of the gravity hammer 8, facilitating the insertion of the measuring rod 3 into the silt.
[0046] The measuring rod 3 is tubular, and a scale mark is arranged on the outer surface of the measuring rod 3.
[0047] The tubular structure ensures the strength of the measuring rod 3 while reducing the overall weight, facilitating insertion into the silt, and the hollow design can accommodate the gravity hammer 8, optimizing space utilization.
[0048] After the device is pulled out, the silt leaves marks on the surface of the measuring rod 3, and the user can directly visually determine the position of the marks on the scale mark to obtain the current depth of the silt.
[0049] When the device is used, the user holds the hand-held rod 1, and the base plate 2 is vertically placed on the surface of the silt to be measured. The base plate 2 sinks to contact the silt due to its own weight, and when the base plate 2 contacts the surface of the silt, the silt generates an upward reaction force on the pressing plate 9, pushing the pressing plate 9 to slide upward along the slide column 10.
[0050] When the pressing plate 9 rises, the two trigger rods 11 fixed to the upper end of the slide column 10 move upward synchronously, and the top end of the trigger rod 11 contacts the abutting plate 12 on the limiting hook 5, continuously pushing the abutting plate 12 to make the limiting hook 5 rotate away from the direction of the limiting slot 6 of the measuring rod 3 around the rotating shaft. When the limiting hook 5 completely separates from the limiting slot 6 of the measuring rod 3, the measuring rod 3 is released instantaneously under the action of the force storage spring 4, and is inserted downward into the silt.
[0051] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
