Description

Technical Field

[0001] This utility model relates to the field of sonar installation equipment technology, specifically a quick-assembly and disassembly connection mechanism for forward-looking sonar. Background Technology

[0002] Forward-looking sonar is a core device for underwater detection, obstacle avoidance, and target identification on ships. The efficiency of its installation mechanism, its adaptability, and its structural reliability directly affect the sonar's performance and maintenance costs.

[0003] A search revealed existing technology (application number: CN201720012367.4), which describes a "retractable installation mechanism for a forward-looking sonar on the bottom of a ship." While this utility model solves some of the operational inconveniences of traditional structures, it lacks a quick disassembly and assembly design, relies on power equipment and complex assembly processes, requires specialized tools for disassembly and assembly, is time-consuming and labor-intensive, and cannot be adapted to forward-looking sonars of different shapes, thus limiting its applicability. Furthermore, its structure emphasizes lifting functionality, lacks reinforcing structures on load-bearing parts, and uses a single locking and fixing method, making it susceptible to loosening due to vibrations during ship navigation. Additionally, the lack of an effective sealing and protection structure allows underwater moisture and impurities to easily penetrate internal components, causing damage to core components and making it unsuitable for long-term underwater operation environments.

[0004] Therefore, there is an urgent need for a connection mechanism for forward-looking sonar that combines quick assembly and disassembly with strong adaptability, as well as a stable structure and excellent sealing performance. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-assembly and disassembly connection mechanism for forward-looking sonar.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick-release connection mechanism for forward-looking sonar, comprising a support component for connecting a ship to a connection component, the upper surface of the support component being on one side of the lower surface of the connection component, the connection component being for connecting a ship to a forward-looking sonar, a mounting component being provided on one side of the upper surface of the connection component, the mounting component being for mounting the forward-looking sonar, the lower end of the mounting component abutting against one side of a locking component, the locking component being for locking the mounting component, a sealing ring being provided on the outer wall of the mounting component, the mounting component and the sealing ring being placed below the upper surface of the mounting box in the connection component on both sides, and the locking component being installed inside the mounting box.

[0007] As a further description of the above technical solution:

[0008] The support assembly includes a support block, with one end of a movable page hinged to both ends of one side of the support block, and the upper surface of the support block connected to the lower surface of the support plate.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes a connecting plate, the lower surface of which contacts the upper surface of the bearing plate, and the upper surface of the connecting plate is connected to one side of the mounting box via an arc-shaped connecting block. The interior of the mounting box is hollow.

[0011] As a further description of the above technical solution:

[0012] A reinforcing rib is provided between the side wall of the bearing block and the lower surface of the bearing plate. Connection holes are provided around the bearing plate and the connecting plate for connecting the bearing block and the connecting plate.

[0013] As a further description of the above technical solution:

[0014] The mounting assembly includes a mounting post, the upper end of which is threaded for connecting a forward-looking sonar, and a sliding groove is provided on one of its lower ends. A locking hole is provided on the upper side of the mounting post near the sliding groove.

[0015] As a further description of the above technical solution:

[0016] The locking assembly includes a locking member. The upper and lower ends of the locking member are provided with protrusions. The lower two sides of the locking member are connected to the inner wall of the mounting box via a pivot. The lower end of the locking member away from the protrusion is connected to one end of a spring, and the other end of the spring is connected to the inner wall of the mounting box. The upper end of the locking member away from the protrusion abuts against a protrusion on one side of a limiting block. The middle two sides of the limiting block are connected to the inner wall of the mounting box via a pivot.

[0017] As a further description of the above technical solution:

[0018] The upper end of the limiting block, away from the protrusion, is connected to one end of a spring, and the other end of the spring is connected to the inner wall of the mounting box. The lower end of the limiting block, away from the protrusion, abuts against one end of an unlocking post. The other end of the unlocking post penetrates the mounting box. The side of the unlocking post near the limiting block is connected to the bottom surface of the mounting box via a support block. A pushing ring is provided on the side of the unlocking post away from the limiting block. The pushing ring is connected to the support block via a spring.

[0019] This utility model has the following beneficial effects:

[0020] 1. Through the cooperative design of the locking and mounting components, during installation, simply insert the mounting post with the forward-looking sonar into the mounting box. The locking component will then rotate via the sliding groove, allowing the limit block to automatically engage with the locking hole for locking and fixation. During disassembly, pressing the unlocking post will quickly release the locking structure. Combined with the automatic pop-out function of the spring inside the mounting post, the disassembly and assembly time is greatly reduced. The mounting post is arranged horizontally on both sides, which can accommodate forward-looking sonars of different shapes, thus broadening the applicability of the mechanism.

[0021] Second, the load-bearing components are reinforced with stiffeners to enhance the connection strength between the load-bearing block and the load-bearing plate. The load-bearing plate and the connecting plate are fixed by bolts through the four connecting holes, which improves the overall load-bearing stability. The double abutment structure of the limit block and the locking component in the locking component can effectively limit the rotation of the locking component and prevent loosening after installation. The sealing ring on the outer wall of the mounting column is embedded in the mounting box, which can isolate external moisture and impurities from entering the internal structure, ensuring the service life of core components such as the locking component and making it suitable for the underwater operation environment of ships.

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, this embodiment provides a quick-release connection mechanism for forward-looking sonar, including a support component 1 for connecting a ship to a connection component 3. The upper surface of the support component 1 is on one side of the lower surface of the connection component 3. The connection component 3 is used for connecting a ship to a forward-looking sonar. An installation component 4 is provided on one side of the upper surface of the connection component 3 for installing the forward-looking sonar. The lower end of the installation component 4 abuts against one side of a locking component 7 for locking the installation component 4. A sealing ring 5 is provided on the outer wall of the installation component 4. The installation component 4 and the sealing ring 5 are placed inside the upper surface of the mounting box 302 in the connection component 3. The locking component 7 is installed inside the mounting box 302.

[0033] In this embodiment, the supporting component 1, the connecting component 3, the mounting component 4, and the locking component 7 constitute a quick-release connection mechanism for forward-looking sonar according to this application.

[0034] It should also be noted that the forward-looking sonar in this application can be a mechanically scanned forward-looking sonar, an electronically scanned forward-looking sonar, a high-power deep-sea exploration forward-looking sonar, etc. Figure 1 In this embodiment, a mechanical scanning forward-looking sonar is used as an example for description. Of course, other types of forward-looking sonars can also adopt a similar structure, which will not be described in detail below.

[0035] Understandable, Figure 1 The quick-release connection mechanism is shown only schematically, and the actual shape, size, position, and construction of these components are not subject to change. Figure 1 Due to limitations, quick-release connection mechanisms can also include those that are more advanced than... Figure 1 More or fewer parts.

[0036] In addition, in this embodiment, a nitrile rubber annular sealing ring 5 is fitted on the middle of the outer wall of the mounting component 4. The bearing component 1 connects the ship and the connecting component 3. The connecting component 3 supports the mounting component 4. After the mounting component 4 is inserted into the mounting box 302, it is locked by the locking component 7. The sealing ring 5 seals the gap, realizing the basic connection between the ship and the sonar, and providing sealing protection.

[0037] Specifically, the support component 1 includes a support block 101, with one end of the movable page 103 hinged to both ends of one side of the support block 101, and the upper surface of the support block 101 connected to the lower surface of the support plate 102.

[0038] In this embodiment, the bearing component 1 includes a stainless steel cuboid bearing block 101. Stainless steel rectangular sheet movable flaps 103 are respectively hinged to both ends of one side of the bearing block 101. The lower surface of the stainless steel rectangular plate bearing plate 102 is horizontally fixed to the upper surface of the bearing block 101. The movable flaps 103 are bent to adjust the angle so that their inner walls are close to the bottom of the ship and then welded and fixed, so as to achieve a stable connection between the bearing component 1 and the ship.

[0039] Specifically, the connecting component 3 includes a connecting plate 301, the lower surface of which contacts the upper surface of the bearing plate 102, and the upper surface of the connecting plate 301 is connected to one side of the mounting box 302 through an arc-shaped connecting block. The interior of the mounting box 302 is hollow.

[0040] In a preferred embodiment, the connecting component 3 includes a stainless steel rectangular plate connecting plate 301, which is connected to the bearing plate 102. An arc-shaped connecting block supports the mounting box 302, thereby achieving the connection and bearing of the bearing component 1 and the mounting component 4.

[0041] Example 2:

[0042] A reinforcing rib 2 is provided based on Example 1.

[0043] Specifically, a reinforcing rib 2 is provided between the side wall of the bearing block 101 and the lower surface of the bearing plate 102, and connecting holes 6 are provided around the bearing plate 102 and the connecting plate 301, which are used to connect the bearing block 101 and the connecting plate 301.

[0044] In this embodiment, stainless steel triangular sheet-shaped reinforcing ribs 2 are fixed at the angles between the two side walls of the bearing block 101 and the lower surface of the bearing plate 102. The reinforcing ribs 2 enhance the structural strength. Bolts pass through the connecting holes 6 to fix the bearing plate 102 and the connecting plate 301, thereby improving the overall bearing stability and preventing the connection from loosening.

[0045] Specifically, the mounting component 4 includes a mounting post 401, the upper end of which is threaded for connecting to a forward-looking sonar, and a sliding groove 402 is provided on the lower side end of the mounting post 401. A locking hole 403 is provided on the upper side of the mounting post 401 near the sliding groove 402.

[0046] With this configuration, the mounting component 4 includes an aluminum alloy cylindrical mounting post 401. The upper end of the mounting post 401 is threaded to the sonar, and the lower end is inserted into the mounting box 302. The sliding groove 402 and the locking hole 403 cooperate to lock the component 7, thereby realizing the installation and fixation of the sonar and providing a matching basis for the locking structure.

[0047] Example 3:

[0048] A locking component 7 is provided based on embodiment 2.

[0049] Specifically, the locking assembly 7 includes a locking member 701. The upper and lower ends of the locking member 701 are provided with protrusions. The lower two sides of the locking member 701 are connected to the inner wall of the mounting box 302 through a rotating shaft. The lower end of the locking member 701 away from the protrusion is connected to one end of a spring, and the other end of the spring is connected to the inner wall of the mounting box 302. The upper end of the locking member 701 away from the protrusion abuts against the protrusion on one side of the limiting block 702. The middle two sides of the limiting block 702 are connected to the inner wall of the mounting box 302 through a rotating shaft.

[0050] When the mounting post 401 is inserted, it compresses the locking member 701 to rotate, the spring deforms, and the protrusion of the limiting block 702 is engaged in the locking hole 403, thereby realizing the automatic locking and fixing of the mounting component 4.

[0051] Specifically, the upper end of the limiting block 702, away from the protrusion, is connected to one end of a spring, and the other end of the spring is connected to the inner wall of the mounting box 302. The lower end of the limiting block 702, away from the protrusion, abuts against one end of the unlocking post 704. The other end of the unlocking post 704 penetrates the mounting box 302. The side of the unlocking post 704 near the limiting block 702 is connected to the bottom surface inside the mounting box 302 via a support block 703. A pushing ring 705 is provided on the side of the unlocking post 704 away from the limiting block 702. The pushing ring 705 is connected to the support block 703 via a spring.

[0052] In this embodiment, pressing the unlocking post 704 drives the pushing ring 705 to push the limiting block 702 to rotate, and the spring reset drives the locking member 701 to disengage from the locking hole 403, thereby realizing the quick unlocking and disassembly of the installation component 4.

[0053] In actual use, first, the movable flap 103 is bent to adjust its angle so that its inner wall is tightly against the bottom of the ship. Then, the movable flap 103 is welded to the bottom of the ship. Next, the connecting plate 301 is connected to the connecting plate 301 around the connecting plate 301 using bolts through the connecting holes 6 on the support plate 102. Then, the thread on the upper end of the mounting post 401 is screwed into the threaded hole on the lower surface of the forward-looking sonar. Because the mounting post 401 is placed horizontally on both sides, it can accommodate forward-looking sonars of different shapes. After the bottom end of the mounting post 401 passes through the sealing ring 5, it is inserted into the mounting box 302. At this time, the lower end of the mounting post 401 compresses the spring, and the sliding groove 402 on one side of the lower end of the mounting post 401 contacts the protrusion at the lower end of the locking member 701. The protrusion slides in the sliding groove 402. As the mounting post 401 continues to be inserted, the sliding groove 402 drives the lower end of the locking member 701 to rotate along the shaft and compress the spring, thereby causing the protrusion at the upper end of the limiting block 702 to insert into the locking hole 403. At this time, the limiting block 702... 2. The upper spring pushes the limiting block 702 to rotate along the pivot, so that the protrusion in the middle of the limiting block 702 abuts against one side of the upper end of the locking member 701, thereby restricting the rotation of the locking member 701. At this time, the installation of the forward-looking sonar is completed. If the forward-looking sonar needs to be replaced, press the unlocking post 704 on the outer wall of the mounting box 302. The unlocking post 704 drives the pushing ring 705 to move and compress the spring between the pushing ring 705 and the support block 703. Then, the other end of the unlocking post 704 pushes the limiting block 702. The lower end of 02 is moved so that the limiting block 702 rotates along the pivot and compresses the spring. At this time, the spring on the lower end of the locking member 701 pushes the locking member 701 to rotate along the pivot, so that the protrusion at the upper end of the locking member 701 moves away from the locking hole 403, thereby unlocking the mounting post 401. At the same time, the spring inside the mounting post 401 extends and pushes the mounting post 401 to rise, so that the locking hole 403 moves away from the protrusion of the locking member 701 to unlock. Then the mounting post 401 can be pulled out.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
