Description

Technical Field

[0001] The utility model belongs to the technical field of water depth measurement, in particular to a water depth survey device. Background Art

[0002] In water depth survey work in rivers, lakes, and seas, traditional water depth measurement methods usually use sounding rods, sounding hammers, or sonar equipment. However, these methods have certain limitations and inconveniences. For example, sounding rods and sounding hammers require manual operation, have low work efficiency, and are easily affected by water currents and wind and waves; although sonar equipment can provide relatively accurate water depth data, it is expensive and has high technical requirements for operators.

[0003] In order to solve the above problems, some new water depth survey devices have emerged in recent years, such as the method of using a steel wire measuring rope in conjunction with a submerged anchor. This device fixes one end of the steel wire measuring rope on a winding mechanism and connects the other end to a submerged anchor, and uses the gravity of the submerged anchor to make the steel wire measuring rope sink vertically to the bottom of the water, thereby measuring the water depth. However, this method still has some problems during use, such as it is difficult to judge whether the steel wire measuring rope is in a vertical state in the water, and it is difficult to control the tension of the steel wire measuring rope (when it is tight, it may cause the submerged anchor below to move) or the relaxation state, and there are errors in the measured water depth.

[0004] Therefore, the utility model aims to provide a water depth survey device which has a simple structure, is easy to operate, and can effectively avoid measurement errors caused by loose or tight wire measuring ropes. Utility Model Content

[0005] The utility model aims to provide a water depth survey device, which realizes accurate measurement of water depth through a pay-out frame, a winding mechanism, a steel wire measuring rope, a submerged anchor, a floating guide and a rope hook.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model discloses a water depth survey device, comprising a pay-out frame, a winding mechanism, a steel wire measuring rope, a submerged anchor and a rope hook; the pay-out frame comprises a mounting base; an inverted L-shaped rod frame is fixed to the upper surface of the mounting base; two reversing wheels are fixed to the lower surface of the horizontal rod portion of the L-shaped rod frame; the submerged anchor comprises a submerged cylinder and a weight placed inside the submerged cylinder; the winding mechanism is mounted on the mounting base; one end of the steel wire measuring rope is fixed and wound on the roller of the winding mechanism; the other end of the steel wire measuring rope passes around the two reversing wheels, passes through the submerged cylinder, and is connected and fixed to the weight, and the height of the weight is less than half of the height of the inner cavity of the submerged cylinder.

[0008] As a preferred technical solution of the utility model, a hook for hanging the rope hook is fixed on one side of the upright pole of the L-shaped pole frame.

[0009] As a preferred technical solution of the utility model, the submerged cylinder includes a conical barrel which is small at the top and large at the bottom and open at the lower end; a circular ring plate is fixed to the lower end of the conical barrel; a circular through hole for passing the steel wire measuring rope is opened in the center of the top surface of the conical barrel; and a plurality of water inlet and outlet holes are opened on the wall of the conical barrel.

[0010] As a preferred technical solution of the utility model, the rope hook includes a J-shaped rod body; a grip ring is fixed to the straight end of the J-shaped rod body.

[0011] As a preferred technical solution of the utility model, it also includes a floating guide; the steel wire measuring rope runs through the center of the floating guide; the floating guide is placed between the submerged anchor and the wire-laying frame.

[0012] As a preferred technical solution of the utility model, the floating guide includes a floating body with a hollow cylindrical structure; a round tube for passing the steel wire measuring rope is fixed through the center of the floating body; a bell mouth is fixed at each end of the round tube.

[0013] As a preferred technical solution of the utility model, the peripheral side surface of the floating body is provided with a plurality of circles of parallel annular protrusions.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model combines a pay-off frame, a winding mechanism, a steel wire measuring rope, a submerged anchor and a rope hook. The submerged anchor adopts a cone barrel structure with a small top and a large bottom. A circular ring plate is fixed at the bottom. A round through hole for passing the steel wire measuring rope is opened in the center of the top surface. A plurality of water inlet and outlet holes are opened on the barrel wall. This design enables the submerged anchor to drain water conveniently when sinking and rising, reduces deflection when sinking, and ensures the stability of the submerged anchor. After the submerged anchor touches the bottom, the rope hook is used to tighten the steel wire measuring rope, so that accurate water depth data can be obtained by conveniently reading the corresponding depth of the nearest scale mark buckle above the water surface minus the distance from the water surface.

[0016] 2. The floating guide of the utility model is installed with a wire measuring rope, which is placed between the submerged anchor and the pay-off frame. The interior is a floating body with a hollow cylindrical structure, and a round tube for passing the wire measuring rope is fixed through the center. The inner diameter of the round tube is 1.5-2 times the maximum outer diameter of the wire measuring rope, and a flare is fixed at both ends to avoid jamming of the wire measuring rope when passing through. In addition, a plurality of parallel annular protrusions are arranged on the side surface of the floating body to facilitate observation of the inclination of the floating guide on the water surface, thereby facilitating judgment of whether the wire measuring rope is in a vertical state in the water, and facilitating judgment of the accuracy of the measurement results.

[0017] 3. Compared with high-precision but high-cost equipment such as sonar equipment, the water depth survey device of the utility model has a simple structure and low cost, and is suitable for large-scale promotion and application.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0031] See also Figure 1-7 As shown, the utility model is a water depth survey device, including a pay-out frame 1, a winding mechanism 2, a steel wire measuring rope 3, a submerged anchor 4 and a rope hook 5. The steel wire measuring rope 3 includes a steel wire rope body and scale marking buckles evenly fixed on the steel wire rope body, and the corresponding number of meters is engraved on the scale marking buckles. The pay-out frame 1 includes a mounting base 11. An inverted L-shaped rod frame 12 is fixed on the upper surface of the mounting base 11. Two reversing wheels 13 are fixed on the lower surface of the horizontal rod portion of the L-shaped rod frame 12. The submerged anchor 4 includes a submerged cylinder 41 and a weight 42 placed inside the submerged cylinder 41. The winding mechanism 2 is installed on the mounting base 11. One end of the steel wire measuring rope 3 is fixed and wound on the roller of the winding mechanism 2. The other end of the steel wire measuring rope 3 passes through the two reversing wheels 13, passes through the submerged cylinder 41, and is connected and fixed to the weight 42, and the height of the weight 42 is less than half the height of the inner cavity of the submerged cylinder 41. When the steel wire measuring rope 3 is connected to the submerged anchor 4, the submerged cylinder 41 is placed on the ground, and the free end of the steel wire measuring rope 3 passes through the submerged cylinder 41 and is pre-connected with the weight 42. The weight 42 is lifted to the inner top of the submerged cylinder 41, and the scale marking buckle closest to the submerged anchor 4 when the steel wire measuring rope 3 is connected to the submerged anchor 4 is lifted to a height position relative to the ground, the steel wire rope body between the scale marking buckle and the weight 42 is tightened and the weight 42 is fixedly connected to it, thereby completing the measurement difference of the steel wire measuring rope 3 caused by the connection of the steel wire measuring rope 3 to the submerged anchor 4.

[0032] In order to facilitate placement of the rope hook 5 when it is not in use, a hook 14 for mounting the rope hook 5 is fixed on one side of the vertical pole of the L-shaped pole frame 12. The rope hook 5 includes a J-shaped rod body 51. A grip ring 52 is fixed to the straight end of the J-shaped rod body 51. When the rope hook 5 is not in use, one end of the J-shaped rod body 51 and one end of the grip ring 52 can be conveniently placed on the hook 14 for placement.

[0033] Among them, the submersible cylinder 41 includes a conical barrel 411 which is small at the top and large at the bottom and is open at the lower end. A circular ring plate 412 is fixed to the lower end of the conical barrel 411. A circular through hole 413 for passing the wire measuring rope 3 is provided in the center of the top surface of the conical barrel 411. A plurality of water inlet and outlet holes 414 are provided on the barrel wall of the conical barrel 411. The design of the submersible cylinder 41 facilitates drainage during sinking and rising, and reduces deflection during the sinking process. The weight of the submersible cylinder 41 of this embodiment is greater than 25KG, which reduces deflection during the sinking process, and avoids easy movement of the submersible cylinder 41 when the wire measuring rope 3 is pulled later.

[0034] like Figure 1 As shown, when surveying the water depth of rivers, lakes and seas, the boat is driven to the measuring point and anchored. The winding mechanism 2 is started to release the steel wire measuring rope 3, and the steel wire measuring rope 3 passes through the two reversing wheels 13 on the pay-off frame 1 and sinks vertically to the bottom of the water under the gravity of the submerged anchor 4. After the submerged anchor 4 contacts the bottom of the water, the steel wire measuring rope 3 becomes loose, and the pay-off operation of the winding mechanism 2 is stopped at this time. The rope hook 5 is hooked on the steel wire measuring rope 3 between the two reversing wheels 13 and pulled up and down. When the weight 42 hits the inner top of the submerged cylinder 41 and can no longer easily pull the steel wire measuring rope 3, the rope hook 5 is stopped from being pressed down, and the position of the rope hook 5 is maintained. At this time, a tape measure is used to measure the distance h from the scale mark buckle closest to the water surface to the water surface, and the number H on this scale mark buckle is read. The water depth at this time is Hh. After the measurement is completed, the rope hook 5 is removed, and the winding mechanism 2 is started again to retract the steel wire measuring rope 3 to prepare for the next measurement. The water depth survey device of the utility model effectively avoids the measurement error caused by the loosening or tightening of the steel wire measuring rope 3 .

[0035] In order to determine whether the steel wire measuring rope 3 is in a vertical state in the water, and to avoid the measurement error caused by the inclination of the steel wire measuring rope 3 caused by the movement of the hull after the submerged anchor 4 sinks to the bottom of the water, a floating guide 6 is also provided. The steel wire measuring rope 3 passes through the center of the floating guide 6. The floating guide 6 is placed between the submerged anchor 4 and the pay-off frame 1.

[0036] The specific structure of the floating guide 6 includes a floating body 61 of a hollow cylindrical structure. A round tube 62 for passing the wire measuring rope 3 is fixed through the center of the floating body 61. The inner diameter of the round tube 62 is 1.5-2 times the maximum outer diameter of the wire measuring rope 3. A bell mouth 63 is fixed at each end of the round tube 62, and the design of the bell mouth 63 prevents the wire measuring rope 3 from getting stuck when passing through.

[0037] In order to facilitate observation of the inclination of the floating guide 6 on the water surface, a plurality of parallel annular protrusions are arranged on the side surface of the floating body 61. When the annular protrusions of the floating body 61 in contact with the water surface are the same annular protrusions, it indicates that the floating guide 6 is in a horizontal state.
