Description

Technical Field

[0001] The utility model belongs to the technical field of marine engine room monitoring and alarm devices, in particular to a marine engine room monitoring and alarm device which is easy to install. Background Art

[0002] The engine room monitoring and alarm system is a ship's most critical monitoring device and one of the earliest systems to incorporate computer technology into engine room automation. Its primary function is to monitor the operating status of various equipment in the engine room (such as the main engine, auxiliary engines, steering gear, oil purifier, boiler, power station, air compressor, pumps, and oil and water tanks) on behalf of the engine room crew. The computer for this system is typically installed in the engine room control room and is essential for achieving an unmanned engine room.

[0003] Existing marine engine room monitoring alarm devices are generally fixed to the support columns in the engine room by bolts and clamps. The installation process is cumbersome and inconvenient to install and remove the alarm device. In addition, since the size of the clamp is usually fixed, the alarm device can only be installed on the support column that is compatible with the inner diameter of the clamp, which limits the installation range. Summary of the Invention

[0004] The purpose of the utility model is to provide a marine engine room monitoring alarm device which is easy to install. The alarm device body is easy to install and disassemble, and the installation range is expanded.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a marine engine room monitoring alarm device that is easy to install, comprising an alarm device body, wherein the right side wall of the alarm device body is provided with two upper and lower limit grooves, wherein two upper and lower arc-shaped fixed gear rings are slidably connected inside the limit grooves, wherein the two fixed gear rings are slidably connected to each other, wherein a rotating drum located on the left side of the fixed gear ring is rotatably connected inside the limit groove, wherein the other end of the rotating drum is fixedly connected to a first gear meshed with the upper fixed gear ring, wherein the rotating drum is movably connected to a rotating shaft, wherein the other end of the rotating shaft extends below the first gear and is fixedly connected to a second gear meshed with the lower fixed gear ring;

[0006] The right side wall of the alarm device body is provided with a tightening mechanism located between the two limiting grooves.

[0007] In order to stably install the alarm device body to the outer wall of the support column, as a preferred embodiment of the present invention, a marine engine room monitoring alarm device that is easy to install, the tightening mechanism includes a groove opened on the right side wall of the alarm device body, and a tightening block is slidably connected to the inside of the groove, and a plurality of evenly distributed springs are fixedly connected between the groove and the tightening block.

[0008] In order to drive the rotating drum and the rotating shaft to rotate in opposite directions, as a preferred marine engine room monitoring alarm device that is easy to install in the present invention, a cavity is opened inside the alarm device body, one end of the rotating drum extends to the inside of the cavity and is fixedly connected to a first bevel gear, one end of the rotating shaft extends to the top of the first bevel gear and is fixedly connected to a second bevel gear, and the interior of the cavity is rotatably connected to a third bevel gear that is meshed with the first bevel gear and the second bevel gear.

[0009] In order to provide power for the rotation of the third bevel gear, as a preferred easy-to-install marine engine room monitoring alarm device of the present invention, a motor is installed on the left side wall of the alarm device body, and the output end of the motor is fixedly connected to the third bevel gear.

[0010] In order to make the tightening block fit tightly with the supporting column, as a preferred embodiment of the marine engine room monitoring and alarm device that is easy to install according to the present invention, the right side wall of the tightening block is configured as an arc structure.

[0011] In order to increase the friction between the support column and the fixed gear ring and the tightening block, as a preferred easy-to-install marine engine room monitoring and alarm device of the present invention, the inner wall of the fixed gear ring and the right side wall of the tightening block are fixedly connected with anti-slip pads.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When the alarm device body needs to be installed, the rotating drum cooperates with the first gear to drive the fixed gear ring located above to slide in the limit groove, so that one end of the fixed gear ring located above slides to the right, and the rotating shaft cooperates with the second gear to drive one end of the fixed gear ring located below to slide to the right, so that the two fixed gear rings form a circular ring structure, so that the circular ring structure formed by the two fixed gear rings is sleeved on the outer wall of the support column. At the same time, the spring pushes the tightening block to move. Through the mutual cooperation between the tightening block and the support column, the tightening block drives the alarm device body to move in the opposite direction of the support column, so that the inner wall of the circular ring structure formed by the two fixed gear rings abuts against the support column, thereby conveniently and quickly stably installing the alarm device body to the outer wall of the support column; when the alarm device body needs to be disassembled, the reverse operation can be performed; in addition, the position of the tightening block can be changed by the spring according to the thickness of the support column, so that the distance between the tightening block and the circular ring formed by the two fixed gear rings is changed to adapt to support columns of different thicknesses and expand the installation range of the alarm device body.
