Description

Technical Field

[0001] The present invention relates to the technical field of sonar installation, and in particular to a fixed-point scanning sonar shipboard portable installation device and a use method thereof. Background Art

[0002] Since electromagnetic waves attenuate very quickly in water, they cannot accurately detect, locate, and communicate with underwater targets, so they are not suitable for marine surveying and mapping. In contrast, sound waves are propagable in water and can accurately detect underwater objects for ships as a basis for navigation. Currently, fixed-point scanning sonar is widely used in marine engineering projects and is an acoustic wave detection instrument for detecting the location of underwater targets.

[0003] During use, the device needs to sink vertically to the seabed and operate in a stable environment. Since the fixed-point scanning sonar instrument has high requirements for the stability of the seabed environment, a large, heavy and stable installation device is required to assist the operation.

[0004] In addition, the installation device requires workers to repeatedly install and disassemble it during use, so it places high demands on the stability and convenience of the installation device. Traditional fixed-point scanning sonars mostly use two types of installation devices for operation. One is a complete and large installation device that cannot be folded, which is inconvenient to transport and has high requirements for ships. It is difficult to apply to smaller work boats and requires long-term use of ship lifting equipment, which greatly reduces work efficiency. The other is an installation device composed of scattered parts. The parts of the installation device are scattered and need to be assembled in a stable environment. However, during ocean navigation, there is a lack of a stable assembly environment, which leads to problems such as difficulty in assembly, easy loss of parts, and unstable use. Summary of the invention

[0005] The problem to be solved by the present invention is to provide a portable shipboard installation device for a fixed-point scanning sonar which has a simple installation method, is stable in use, has high applicability to fixed-point scanning sonars, and is easy to install and fold, and a method for using the device.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a portable installation device for fixed-point scanning sonar shipboard, including a top plate, a hanging basket hinged at the center of the lower surface of the top plate for loading the fixed-point scanning sonar instrument, at least three support rods with tops swingably connected to the top plate and protecting the hanging basket therein, and a cross-tie rod correspondingly arranged between two adjacent support rods, one end of the cross-tie rod being hinged to the support rod, and the other end being hinged to a sliding assembly that can slide along the support rod, and the support rod being retracted or opened by sliding or locking the sliding assembly relative to the support rod.

[0007] Furthermore, the top plate is evenly distributed with connecting pins in the circumferential direction, and the connecting pins are movably connected to the supporting rods through a folding shaft.

[0008] Furthermore, the top plate is detachably connected to the hanging basket via a cross shaft and a universal joint fork, and the cross shaft is detachably connected to the universal joint fork.

[0009] Furthermore, the hanging basket is provided with two clamps, and a lifting and shackle is provided at the lower end of the hanging basket, and the hanging basket is movably connected to a counterweight via the lifting and shackle.

[0010] Furthermore, the cross-sectional area of ​​the support rod is circular, which facilitates the sliding assembly to slide on the support rod; and the cross-sectional area of ​​the tie rod is square.

[0011] Furthermore, the support rod has a smooth surface, which helps to reduce the impact of water flow on the installation device in seawater; the cross tie rod is made of high-quality material and can act as a counterweight, creating a stable working environment for the equipment.

[0012] Furthermore, on the same support rod, the sliding component is arranged at the upper end of the hinged end, which can facilitate the sliding component to slide upwards.

[0013] Furthermore, the sliding assembly includes a connecting shaft and a sliding block, which are integrally arranged, the connecting shaft is hinged to the transverse tie rod, the connecting shaft is fixedly connected to the sliding block, and the sliding block is sleeved on the outside of the support rod, so that the equipment can be flexibly installed and folded during use. When the equipment is folded, the sliding block slides to the upper end of the support rod, and at this time, there is relative rotation between the transverse tie rod, the connecting shaft and the support bearing.

[0014] Furthermore, the sliding block is provided with a clamping hole, in which a limiting top screw is provided. The sliding block is clamped with the support rod through the limiting top screw, and the sliding block can be fixed on the support rod through the limiting top screw to prevent the sliding of the sliding block during use from causing instability and damage to the instrument.

[0015] Furthermore, an anti-sinking angle is fixedly connected to the bottom of the support rod, and the anti-sinking angle can increase the contact area between the device and the seabed mud, thereby preventing the device from sinking into the mud and increasing the stability of the device.

[0016] Furthermore, a drainage and sand prevention hole is provided at the bottom end of the anti-sinking bottom angle, which reduces the buoyancy of the device during entering the sea; during the rising process, it plays a drainage role, discharges seawater from the support rod, and protects the device from seawater erosion.

[0017] Furthermore, a sand-proof net is provided between the anti-sinking angle and the support rod to prevent mud and sand from entering the interior of the device and reducing the service life of the device.

[0018] Furthermore, the surface of the top plate is provided with a cable opening, through which the cable of the fixed-point scanning sonar can be neatly fixed, thereby reducing space occupancy and the risk caused by cable damage.

[0019] Furthermore, the device is made of 316 stainless steel to ensure that the device is strong, durable and will not fade or deform.

[0020] Furthermore, an instrument protection ring is provided at the lower end of the hanging basket, and the diameter of the instrument protection ring is larger than the clamp. The instrument protection ring is welded to the hanging basket, and together with the clamp, it plays a role in stabilizing the fixed-point scanning sonar hanging basket and protecting the fixed-point scanning sonar instrument.

[0021] The method of using the fixed-point scanning sonar shipboard portable installation device comprises the following steps:

[0022] Step 1: Select the landing point, erect the installation device, stretch the support rod to make the sliding block slide to the bottom;

[0023] Step 2: Hold the support rod tightly, rotate the limit screw and fix it;

[0024] Step 3: Install the hanging basket and place the fixed-point scanning sonar instrument into the hanging basket;

[0025] Step 4: Adjust the clamp to fix the fixed-point scanning sonar instrument;

[0026] Step 5: Lift the shackle, hang the counterweight, and then sink the device vertically to the seabed.

[0027] Compared with the prior art, the present invention has the following advantages and positive effects:

[0028] (1) By providing anti-sinking angles, limit screws, limit pins, support rods and horizontal tie rods, it is convenient for marine exploration personnel to quickly support and fix the installation device. By using the principle of triangle stability, the fixed-point scanning sonar equipment can be stably supported in rough seas.

[0029] (2) The cross axis at the bottom of the top plate is connected to the universal joint fork at the top of the fixed-point scanning sonar basket to form a universal joint, which can ensure that the fixed-point scanning sonar is always perpendicular to the horizontal plane on a smooth seabed.

[0030] (3) A counterweight is installed at the bottom of the basket to ensure the balance of the instrument basket, so that the fixed-point scanning sonar is always perpendicular to the seabed during operation, preventing the instrument from being displaced significantly by the impact of water flow and causing data distortion.

[0031] (4) The support rod and the cross rod are slidably connected to form the device into a foldable whole. On the one hand, the folding method saves storage space and is easy to carry; on the other hand, the installation device can instantly form a large instrument support frame when in use, saving the installation time of the instrument installation device.

[0032] (5) A sand-proof net is installed inside the bottom of the support rod to filter out the sediment in the seawater and prevent the sediment from accumulating and corroding the installation device.

[0033] (6) Five drainage and sand prevention holes are provided at the anti-sinking bottom corners to reduce the resistance encountered by the installation device during the sinking process and improve the stability of the installation device. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The top plate 4 is detachably connected to the hanging basket 12 through the cross shaft 6 and the universal joint fork 10, the cross shaft 6 is detachably connected to the universal joint fork 10, and the bottom end of the top plate 4 is movably connected to the hanging basket 12 through the universal joint fork 10, so that the instrument is always perpendicular to the sea level during the process of going into the sea, preventing the instrument from being damaged due to bumps and improving the accuracy of the instrument's detection.

[0048] The hanging basket 12 is provided with two clamps 11, which can be installed and fixed according to the circumference of the fixed-point scanning sonar to reduce the damage to the instrument caused by shaking due to the impact of water flow. A lifting buckle 13 is provided at the lower end of the hanging basket 12. The hanging basket 12 is movably connected with a counterweight 14 through the lifting buckle 13, which can enhance the balance of the hanging basket 12, so that it can better resist buoyancy and maintain stability during entering the sea and operation.

[0049] The sliding assembly includes a connecting shaft 15 and a sliding block 16. The connecting shaft 15 is hinged to the transverse tie rod 2. The connecting shaft 15 is fixedly connected to the sliding block 16. The sliding block 16 is sleeved on the outside of the support rod 3. The sliding block 16 is provided with a clamping hole.

[0051] Embodiment 1:

[0052] When using:

[0053] like Figure 1-Figure 9 As shown:

[0054] Step 1: The user can first take out the fixed-point scanning sonar shipboard portable installation device, lay it flat on the deck, select the instrument landing point, and then stand up the installation device and stretch two of the support rods 3 until the bottom anti-sinking bottom angle 1 fits tightly with the deck, so that the sliding block 16 slides from the top of the support rod 3 to the bottom, so that the cross tie rod 2 and the support rod 3 form a tetrahedron bracket for support;

[0055] Step 2: Fix the fixed-point scanning sonar shipboard portable installation device, then the user holds the support rod 3 with one hand, and rotates the limit screw 8 in the direction of the support rod 3 with the other hand to fix it, and then completes the support and fixation of the main body of the fixed-point scanning sonar shipboard portable installation device. By using the principle of triangle stability, the instrument stand can be stably and conveniently placed on the shaking hull deck.

[0056] Step 3: The cross axis 6 provided in combination with the top plate 4 facilitates the user to quickly install the hanging basket 12 on the shaking hull. Since it is inevitable to encounter bad natural weather during sailing on the unpredictable sea, it is extremely difficult for the marine surveying and mapping personnel to install and protect the equipment. In order to simplify the installation procedure and protect the equipment, the user then places the fixed-point scanning sonar instrument into the hanging basket 12;

[0057] Step 4: Fix the fixed-point scanning sonar instrument by adjusting the tightness of the clamp 11. Tightening the clamp 11 can prevent the fixed-point scanning sonar instrument from shaking in the hanging basket 12. After being fixed by two clamps 11, the universal joint fork 10 is movably connected with the cross shaft 6, and the hanging basket 12 is hung on the top plate 4;

[0058] Step 5: Then hang the counterweight 14 on the lower end of the hanging basket 12 through the lifting shackle 13, and then sink the device vertically to the seabed, so that the anti-sinking corner 1 is closely fitted with the surface of the seabed mud.

[0059] Embodiment 2:

[0060] When disassembling:

[0061] like Figure 1-Figure 9As shown: the user lifts the device from the seabed through the ship's lifting device, takes out the fixed-point scanning sonar shipboard portable installation device, and lays it flat on the deck. Then the user removes the counterweight 14 from the lower end of the hanging basket 12 through the lifting shackle 13, and then disassembles the universal joint fork 10 and the cross shaft 6, removes the hanging basket 12 from the top plate 4, and disassembles the fixed-point scanning sonar instrument by adjusting the tightness of the clamp 11, loosens the clamp 11, and then removes the fixed-point scanning sonar instrument from the hanging basket 12. To take it out, the user holds the support rod 3 tightly with one hand and rotates the limit screw 8 in the opposite direction of the support rod 3 with the other hand to loosen it, so that the sliding block 16 can slide in the direction of the support rod 3, and the installation device is erected and two of the support rods 3 are folded. The sliding block 16 is pushed by hand to slide from the bottom end of the support rod 3 to the top end, so that the cross rod 2 and the support rod 3 are folded, and the fixed-point scanning sonar ship side portable installation device can be disassembled and stored.

[0062] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of this patent.
