Description

Technical Field

[0001] The present invention belongs to the technical field of underwater acoustic measurement, and specifically relates to a double-drive opening and closing mechanism for a sound pipe. Background Art

[0002] Sound pipes are common measurement devices in the field of underwater acoustic measurement. Currently, there are two common ways to open and close sound pipes. One is the fully manual opening and closing method, which uses a bolt-nut method to seal and close the sound pipe and the lid. During the opening and closing process, manual loosening or tightening of bolts is required, which is time-consuming and laborious, and has poor safety. The other is to use a hydraulic drive to achieve the opening and closing of the sound pipe. This method has high efficiency, saves time and effort, but the system is relatively complex and requires hydraulic equipment, pipelines, and control systems, with high requirements for the site and cost. Summary of the Invention

[0003] In view of the above deficiencies and defects of the prior art, the present invention provides a double-drive opening and closing mechanism for a sound pipe, which uses double motors for symmetric drive, operates smoothly and reliably, has good safety, can achieve automatic opening and closing of the sound pipe, has a relatively simple overall structure, low cost, symmetric force on both sides of the sound pipe lid, and good sealing performance.

[0004] To solve the above technical problems, the present invention provides the following technical solution: A double-drive opening and closing mechanism for a sound pipe, used for quickly opening and closing the sound pipe lid, includes an installation platform, a sound pipe lid assembly, a right hoop assembly, a left hoop assembly, and two drive mechanism assemblies.

[0005] The sound pipe lid assembly is installed on the installation platform through the right hoop assembly and the left hoop assembly.

[0006] The two drive mechanism assemblies are respectively connected to the corresponding connecting lugs of the right hoop assembly and the left hoop assembly, and are used to control the opening or closing of the right hoop assembly and the left hoop assembly.

[0007] Preferably, the installation platform includes a sound pipe, a mounting plate, a sealing ring, a positioning pin, and a bearing seat. The upper edge of the sound pipe is wedge-shaped, and the mounting plate is welded to the sound pipe.

[0008] Preferably, the mounting plate has fixing holes for installing the drive mechanism assembly, the positioning pin is used for positioning during the hoisting process of the sound pipe lid assembly, and the bearing seat is used for fixing the drive mechanism assembly.

[0009] Preferably, the sound pipe lid assembly includes a safety valve, a lifting ring screw, a pressure gauge, and a sound pipe lid. The pressure gauge is used to indicate the internal pressure of the sound pipe. When the internal pressure of the sound pipe is too high, pressure relief is carried out through the safety valve.

[0010] Preferably, the eyebolt is used for hoisting the sound pipe lid assembly. The edge of the sound pipe lid is also wedge-shaped. The right hoop assembly and the left hoop assembly are symmetrically arranged on the outer ring of the sound pipe lid assembly.

[0011] Preferably, both the right hoop assembly and the left hoop assembly include a left-handed nut block, a hoop, and a right-handed nut block. The cross-section of the hoop is also wedge-shaped and fits with the upper edge of the sound pipe and the edge of the sound pipe lid.

[0012] Preferably, the driving mechanism assembly is driven by a screw-nut mechanism to achieve self-locking of the sound pipe opening and closing mechanism.

[0013] Preferably, the driving mechanism assembly includes a bearing, a screw, a reducer bracket, a reducer, and a motor. The motor drives the reducer to rotate, drives the screw to rotate, and drives the right hoop assembly and the left hoop assembly to open or close through the left-handed nut block and the right-handed nut block, so that the sound pipe lid presses the sealing ring to achieve the sealing of the sound pipe.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-6 shown, a double-drive opening and closing mechanism for a sound pipe is mainly used for quickly opening and closing the sound pipe lid. The double-drive opening and closing mechanism for the sound pipe mainly consists of components such as an installation platform 1, a sound pipe lid assembly 2, a right hoop assembly 3, a left hoop assembly 4, and a driving mechanism assembly 5.

[0024] The installation platform 1 is composed of a sound pipe 6, an installation plate 7, a sealing ring 8, a positioning pin 9, a bearing seat 10, etc. The upper edge of the sound pipe 6 is wedge-shaped. First, the installation plate 7 is welded to the sound pipe 6. The installation plate 7 has fixing holes for installing the driving mechanism assembly 5. The positioning pin 9 is used for positioning during the hoisting of the sound pipe lid assembly 2. The bearing seat 10 is welded to the installation plate 7 to fix the driving mechanism assembly 5.

[0025] The sound pipe lid assembly 2 is composed of a safety valve 11, a lifting eye bolt 12, a pressure gauge 13, a sound pipe cover 14, etc. The pressure gauge 13 is used to indicate the internal pressure of the sound pipe. When the internal pressure of the sound pipe is too high, pressure is relieved through the safety valve 11. The lifting eye bolt 12 is used for hoisting the sound pipe lid assembly 2. The edge of the sound pipe cover 14 is also wedge-shaped.

[0026] The right hoop assembly 3 is composed of a left-handed nut block 15, a hoop 16, a right-handed nut block 17, etc. The left-handed nut block 15 and the right-handed nut block 17 are respectively fixed on the hoop 16 by bolts. The left hoop assembly 4 has the same components as the right hoop assembly 3, except that the positions of the left-handed nut block 15 and the right-handed nut block 17 are swapped. The cross-section of the hoop 16 is also wedge-shaped and fits with the upper edge of the sound pipe 6 and the edge of the sound pipe cover 14.

[0027] The driving mechanism assembly 5 is composed of a bearing 18, a screw rod 19, a reducer bracket 20, a reducer 21, a motor 22, etc. The motor 22 drives the reducer 21 to rotate, and drives the screw rod 19 to rotate. Through the left-handed nut block 15 and the right-handed nut block 17, the right clamp assembly 3 and the left clamp assembly 4 are driven to open or close, so that the sound pipe cover 14 presses the sealing ring 8 to achieve sound pipe sealing. Since the screw-nut mechanism is adopted for driving in the present invention, self-locking of the sound pipe opening and closing mechanism can be realized.

[0028] Although specific embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
