Description

Technical Field

[0001] The utility model relates to the technical field of underwater equipment, and more specifically, to a diving depth calibrator for an underwater equipment. Background Art

[0002] The underwater equipment mooring buoy is connected by a cable. When the equipment reaches the corresponding water depth position, the controller controls the equipment to operate, so as to open or lock the cable, and the control of the underwater equipment mooring buoy can be realized. Usually, the cable is controlled by an electric device. When the equipment reaches the preset depth, the electric device controls to open or lock the cable. However, the module of the electric device is relatively large, and usually requires a power supply part, a control part and an execution part, which affects the miniaturization of the structure of the underwater equipment.

[0003] The Chinese utility model patent with the publication number of CN220682624U discloses a deep-water diving depth calibration device. The key points of its technical solution are: including a cylinder body, a piston in the cylinder body is connected with a piston rod. The piston rod has a first end arranged in the cylinder body and a second end extending out of the cylinder body. A spring is arranged between the first end and the cylinder body. The cylinder body is provided with a baffle, the baffle is relatively fixed to the cylinder body, and a gap for the cable to pass through is formed between the baffle and the second end of the piston rod. The gap is adjusted as the piston rod expands and contracts. The second end of the piston rod is used to press or release the cable in the gap. This solution can automatically adjust the depth of the equipment according to the water pressure changes at different depths.

[0004] However, in the above solution, the cable passes through the gap between the piston rod and the baffle, and the cable can be clamped and fixed by the expansion and contraction of the piston rod. Since the position of the cable between the piston rod and the baffle can move, it is easy to produce deviation, resulting in that when the cable is clamped, only a small part of the cable may be pressed, affecting the stability of the cable clamping; in addition, in the above solution, an elastic wire tube is also tried to limit the position of the cable, so that the cable can be limited to a relatively central position and can be stably clamped by the piston rod. However, since the wire tube is located outside the cable, the cable cannot be directly clamped by the piston rod and the block, and slippage may occur between the wire tube and the cable, which will also affect the stability of the clamping and fixing.

[0005] The utility model provides a new technical solution to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art, and provide a diving depth calibrator for an underwater equipment, which can accurately determine the depth according to the water pressure and can effectively and stably realize the regulation.

[0007] To achieve the above object, the utility model adopts the following technical solution: A submersible depth calibrator for an underwater device, comprising a cylinder body, one end of the cylinder body is provided with an end cover, a piston in the cylinder body is connected with a piston rod, the piston rod includes a telescopic end, and the telescopic end penetrates through the end cover and extends out; a baffle is fixedly connected to the outside of the end cover, and the telescopic end is located between the end cover and the baffle; a first pressing surface is arranged on one side of the baffle facing the telescopic end, a second pressing surface is arranged on one side of the telescopic end facing the baffle, and a clamping gap is formed between the first pressing surface and the second pressing surface; a cable is arranged in the clamping gap, and the cable can be pressed tightly by the first pressing surface and the second pressing surface; further comprising a cable winding member, at least part of the cable winding member is located in the clamping gap, and the cable is wound around the cable winding member at least once.

[0009] The utility model is further arranged such that at least part of the first convex block extends into the second accommodating hole, and at least part of the second convex block extends into the first accommodating hole.

[0010] The utility model is further arranged such that the first convex block and the second convex block are in a mutually adapted semi-cylindrical structure, and the first convex block and the second convex block enclose a cylindrical structure together.

[0011] The utility model is further arranged such that the cable winding member is wound around the outer periphery of the contours of the first convex block and the second convex block.

[0012] The utility model is further arranged such that two connecting frames are fixedly connected between the baffle and the end cover, and the two connecting frames are respectively located on both sides of the outer periphery of the piston rod.

[0016] The utility model is further arranged such that mounting frames are arranged on the outer sides of both the cylinder body and the baffle.

[0017] In summary, the utility model has the following beneficial effects:

[0018] By providing a rope winding member, the length of the rope between the first pressing surface and the second pressing surface can be increased through winding, and the deviation of the rope can be avoided, so as to prevent the problem that the piston rod cannot tightly press and fix the rope, ensuring that the rope has enough length to be clamped and improving the clamping stability of the rope.

Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] This embodiment discloses a diving depth calibrator for an underwater device. Refer to Figure 1 , Figure 2 , Figure 3 . As shown, it includes a cylinder block 1. One end of the cylinder block 1 is open and is equipped with an end cover 2, and the cylinder block 1 is covered by the end cover 2. A piston in the cylinder block 1 is connected to a piston rod 3, and the piston rod 3 is connected to the inner cavity of the cylinder block 1 through a seal to achieve piston connection.

[0028] The piston rod 3 includes a telescopic end 4, and the telescopic end 4 penetrates through the end cover 2 and extends out to the outside of the end cover 2. A baffle 6 is fixedly connected to the outside of the end cover 2. Between the baffle 6 and the end cover 2, there are two connecting frames 8. The connecting frames 8 are fixedly connected to the baffle 6 and the end cover 2 to form an integral structure.

[0029] The telescopic end 4 is located between the end cover 2 and the baffle 6. On one side of the baffle 6 facing the telescopic end 4, there is a first pressing surface 61 formed, and on one side of the telescopic end 4 facing the baffle 6, there is a second pressing surface 41 formed. A clamping gap 7 is formed between the first pressing surface 61 and the second pressing surface. A cable 13 is passed through the clamping gap 7. When fixation is required, the cable 13 can be pressed tightly through the first pressing surface 61 and the second pressing surface to achieve fixation of the cable 13. When movement is required, the first pressing surface 61 and the second pressing surface 41 loosen the cable 13, and the cable 13 can then move.

[0030] Two connecting frames 8 are fixedly connected between the baffle 6 and the end cover 2. The two connecting frames 8 are respectively located on both outer sides of the piston rod 3. Moreover, both of the two connecting frames 8 are provided with through holes 81, and the two through holes 81 are arranged in a staggered manner. The two ends of the cable 13 respectively extend out from the two through holes 81. Through the positions of the two through holes 81, the cable 13 needs to pass through the clamping gap 7 during the threading process, ensuring that the cable 13 can be stably clamped and fixed.

[0031] Moreover, the piston rod 3 has an annular structure, while the connecting frame 8 has a plate-like structure. The two connecting frames 8 are parallel to each other, and a gap is formed on one side where the piston rod 3 and the connecting frame 8 are close to each other. The minimum gap between the outer periphery of the piston rod 3 and the connecting frame 8 is smaller than the outer diameter of the cable 13. The reduced gap can prevent the cable 13 from being embedded therein, avoiding the cable 13 being accidentally wound around the outer periphery of the piston rod 3 and unable to be tightly fixed through the first pressing surface 61 and the second pressing surface 41.

[0032] To facilitate the fixation of the entire assembly, mounting frames 10 are provided on the outer sides of both the cylinder block 1 and the baffle 6, which can facilitate the installation of the entire assembly at an appropriate position of the device.

[0033] Inside the cylinder block 1, a spring 5 is provided. The spring 5 elastically presses against one end of the piston rod 3 facing away from the telescopic end 4, and the elastic force of the spring 5 is used to push the piston rod 3 out of the end cover 2. Moreover, there is a certain internal pressure in the cylinder block 1, and the internal pressure can be adjusted through the pipeline connected to the cylinder block 1, or the cylinder block 1 can be inflated to have a certain internal pressure.

[0034] During use, the elastic force of the spring 5 and the internal pressure of the cylinder block 1 jointly resist the water pressure on the outer diameter. When the elastic force of the spring 5 and the internal pressure of the cylinder block 1 are greater than the water pressure, the elastic force of the spring 5 and the internal pressure of the cylinder block 1 jointly push the piston rod 3 to move outward, and the first pressing surface 61 and the second pressing surface 41 approach each other, jointly pressing and fixing the cable 13 tightly. When the elastic force of the spring 5 and the internal pressure of the cylinder block 1 are less than the water pressure, the water pressure will push the piston rod 3 to move inward, the first pressing surface 61 and the second pressing surface 41 will separate from each other, and the cable 13 will be relaxed. The cable 13 will not be restricted and can move smoothly.

[0035] Furthermore, the diving depth calibration assembly further includes a rope winding member 9. At least a part of the rope winding member 9 is located in the clamping gap 7, and the cable 13 is wound around the outside of the rope winding member 9 for at least one turn. By winding, the length of the cable 13 between the first pressing surface 61 and the second pressing surface 41 can be increased, and the deviation of the cable 13 can be avoided, thus preventing the problem that the piston rod 3 cannot effectively press and fix the cable 13.

[0036] The rope winding member 9 includes a first convex block 91 and a second convex block 92. Among them, the first convex block 91 is fixedly connected to the first pressing surface 61, and the second convex block 92 is fixedly connected to the second pressing surface 41. The first convex block 91 and the second convex block 92 are in a mutually adapted structure, roughly in a semi-cylindrical structure, and the first convex block 91 and the second convex block 92 jointly enclose a cylindrical structure. The outer peripheries of the first convex block 91 and the second convex block 92 jointly form a structure similar to a circle. The rope winding member 9 is wound around the outer contour of the first convex block 91 and the second convex block 92, so that the cable 13 can smoothly bypass the outer peripheries of the first convex block 91 and the second convex block 92. When the cable 13 is relaxed, it can allow the cable 13 to move smoothly.

[0037] The first pressing surface 61 is provided with a first receiving hole 11, and the first receiving hole 11 is mutually adapted to the second convex block 92. The second pressing surface 41 is provided with a second receiving hole 12, and the second receiving hole 12 is mutually adapted to the first convex block 91. The first receiving hole 11 and the second receiving hole 12 are of appropriate sizes. At least a part of the first convex block 91 extends into the second receiving hole 12, and at least a part of the second convex block 92 extends into the first receiving hole 11. During the process of the first pressing surface 61 and the second pressing surface 41 approaching each other and pressing the cable 13 tightly, a part of the first convex block 91 can be embedded into the second receiving hole 12, and a part of the second convex block 92 can be embedded into the first receiving hole 11, realizing mutual accommodation. In this way, when the rope winding member 9 can allow the cable 13 to bypass, it can also realize pressing and fixing the cable 13.

[0038] Further, referring to Figure 4 As shown, a frustum portion 14 is formed on the side opposite to the pressing surface one 61 and the pressing surface two 41, and the pressing surface one 61 and the pressing surface two 41 form a frustum-like structure. The two frustum portions 14 protrude towards the opposite sides, and the clamping gap 7 is formed between the two frustum portions 14, and the width of the clamping gap 7 gradually decreases in the direction close to the axis. The cable 13 is wound around the cable winding member 9 and is embedded into the clamping gap 7 between the two frustum portions, and the clamping gap 7 forms a structure with a wider outer circumference and a narrower inner circumference.

[0039] During the process that the pressing surface one 61 and the pressing surface two 41 approach each other and press the cable 13, the two frustum portions 14 clamp and fix the cable 13. In the clamped state, if the cable is subjected to a tensile force, the cable will further embed into the inner circumference direction of the clamping gap 7. However, the width in the inner circumference direction of the clamping gap 7 will be smaller. Therefore, the clamping force on the cable 13 will be greater, and thus a more stable clamping effect can be formed to counteract the tensile load on the cable 13.

[0040] The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
