DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Embodiment 1

[0030] like Figure 1-Figure 5 As shown, this embodiment proposes a shallow water underwater topography measuring device, including a hull 1, the hull 1 is slidably connected to a lifting rod 4 that moves in the vertical direction, the lifting rod 4 is slidably connected to a slide plate 13, and scale lines are set on the lifting rod 4. The scale lines can be used to easily judge the length of the lifting rod 4 that penetrates underwater, thereby measuring the silt depth and the depth after siltation.

[0031] The slide plate 13 can only slide along the length direction of the lifting rod 4. When the lifting rod 4 descends, the slide plate 13 can be driven to descend. When the slide plate 13 contacts the silt, the slide plate 13 can no longer descend. At this time, the depth of the silt can be judged, and the lifting rod 4 can continue to descend. When the lifting rod 4 touches the bottom, the lifting rod 4 can no longer descend. The thickness of the silt can be judged according to the scale of the lifting rod 4.

[0032] The lifting rod 4 is fixedly connected to a spring plate 7 arranged above the slide plate 13, and the spring plate 7 is arranged below the slide plate 13. The width of the slide plate 13 is suitable enough to facilitate contact with the silt. A plurality of springs 10 are arranged between the spring plate 7 and the slide plate 13. The upper end of the spring 10 is detachably connected to the spring plate 7, and the lower end of the spring 10 is detachably connected to the slide plate 13.

[0033] The spring plate 7 is provided with a plurality of threaded holes 8, and bolts 9 are connected to the inner threads of the threaded holes 8. The lower ends of the bolts 9 pass through the threaded holes 8 and are detachably connected to the upper ends of the springs 10. Different numbers of bolts 9 can be provided through the threaded holes 8 to achieve adjustment of different numbers of springs 10, thereby adapting to sludge of different densities.

[0034] The upper end of the spring 10 is rotatably connected with a screw rod, the lower end of the bolt 9 is provided with a threaded groove, the lower end of the spring 10 is rotatably connected with a screw rod, the slide plate 13 is provided with a threaded groove, and the screw rod and the threaded groove are threadedly connected. Through the above arrangement, the two ends of the spring 10 can be detached from the bolt 9 and the slide plate 13. According to different work requirements, the appropriate length and the appropriate number of springs 10 can be selected.

[0035] For silt with a higher density, more springs 10 can be added. At this time, the elastic force of the spring 10 is large enough. Only when silt is detected, the position of the slide plate 13 will be relatively static, which can effectively improve the accuracy of silt detection.

[0036] The bolt 9 and the spring 10 have different lengths. The length of the bolt 9 is adapted to the length of the spring 10. When a longer spring 10 is selected, a shorter bolt 9 can be selected to keep the sum of the lengths of the spring 10 and the bolt 9 unchanged. By selecting a spring 10 of appropriate length, the slide plate 13 can be moved a longer distance, which is convenient for detecting thicker sludge.

[0037] The hull 1 is fixedly connected with a sliding block 6, which has a through hole. The lifting rod 4 passes through the through hole and is slidably connected to the through hole. Under the action of the sliding block 6, the movement of the lifting rod 4 is limited so that the lifting rod 4 can only move in the vertical direction.

[0038] The sliding block 6 is fixedly connected with a stop bar 5 which can stop the movement of the sliding block 6. The stop bar 5 is arranged above the sliding block 6. When the stop bar 5 and the sliding block 6 are in contact, the sliding block 6 cannot continue to descend, thereby limiting the movement distance of the sliding block 6.

[0039] The hull 1 is fixedly connected to a motor 2, the motor 2 is connected to a gear 3, and one side of the lifting rod 4 is connected to a rack, the rack and the gear 3 are meshed, and the motor 2 can drive the gear 3 to rotate, and the gear 3 can drive the lifting rod 4 to move in the vertical direction.

[0040] The slide plate 13 is rotatably connected to a shaft 18, and the shaft 18 is fixedly connected to a flap 11. The flap 11 can rotate around the shaft 18. The slide plate 13 is slidably connected to a buckle 12 that can limit the rotation of the flap 11. The flap 11 is connected to the slide plate 13 via a torsion spring.

[0041] One end of the torsion spring is connected to the slide plate 13, and the other end is connected to the flap 11. The flap 11 can be reset by the torsion spring. In the initial state, under the action of the torsion spring, the flap 11 is located above the slide plate 13, and the flap 11 is in a retracted state.

[0042] When the flap 11 is rotated to increase the area of ​​the slide plate 13, the torsion spring can be deformed. By sliding the buckle 12, when the buckle 12 slides to the position of the rotating shaft 18, the buckle 12 will slide to both sides of the flap 11. At this time, under the action of the bayonet 12, the flap 11 can be limited. The buckle 12 is "U"-shaped. By setting the buckle 12 to be sufficiently long and wide, the flap 11 can be limited.

[0043] The lifting rod 4 is also fixedly connected to a fixed plate 19 arranged under the slide plate 13. In the initial state, under the action of the spring 10, the slide plate 13 and the fixed plate 19 are in contact. At this time, the spring 10 is in a compressed state. When the slide plate 13 is in contact with the silt, the fixed plate 19 will continue to descend with the lifting rod 4.

[0044] The fixing plate 19 is connected to the middle conductive block 16, the sliding plate 13 is connected to the upper conductive block 15, and the hull 1 is connected to the indicator light. When the middle conductive block 16 and the upper conductive block 15 are in contact, the indicator light is powered on and lights up. In the initial state, since the sliding plate 13 and the fixing plate 19 are in contact, the middle conductive block 16 and the upper conductive block 15 are in contact, and the indicator light is powered on and lights up.

[0045] When the slide plate 13 contacts the silt, the slide plate 13 no longer descends, and the fixed plate 19 continues to descend following the lifting rod 4, the middle conductive block 16 and the upper conductive block 15 no longer contact, and the indicator light is powered off, indicating that the silt has been detected.

[0046] The bottom end of the lifting rod 4 is connected with a drill bit 14 which is convenient for sliding into water.

[0047] Embodiment 2

[0048] Reference Figure 1-Figure 5 , other structures are the same as those in the first embodiment, except that the detection problem of sludge thickness is taken into consideration in this embodiment.

[0049] The hull 1 is also connected to a warning light, the drill bit 14 and the lifting rod 4 are slidably connected, and a return spring is arranged between the drill bit 14 and the lifting rod 4, and the elastic force of the return spring is large enough.

[0050] The drill bit 14 is connected to a lower conductive block 17. When the lower conductive block 17 and the middle conductive block 16 are in contact, the warning light is powered on and lights up. In the initial state, under the action of the reset spring, there is a certain gap between the drill bit 14 and the fixed plate 19. At this time, the lower conductive block 17 and the middle conductive block 16 are not in contact, and the warning light is off.

[0051] The specific working process is as follows: start the motor 2, the motor 2 drives the gear 3 to rotate, the gear 3 drives the lifting rod 4 to descend, the lifting rod 4 drives the slide plate 13 to descend, when the slide plate 13 contacts the silt, at this time, as the lifting rod 4 continues to descend, the lifting rod 4 drives the fixed plate 19 to descend, and the slide plate 13 does not descend, the middle conductive block 16 and the upper conductive block 15 are no longer in contact, and the indicator light is powered off, indicating that the silt has been detected at this time and the depth of the silt can be measured.

[0052] As the lifting rod 4 continues to descend, when the drill bit 14 contacts the water level, the drill bit 14 cannot continue to descend. As the lifting rod 4 descends, the return spring is compressed. When the lower conductive block 17 contacts the middle conductive block 16, the warning light comes on and the silt thickness can be measured.

[0053] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
