Description

Technical Field

[0001] This utility model relates to the technical field of vibration alarm mounting base, specifically a mounting base for an abnormal vibration alarm for marine equipment. Background Technology

[0002] During ship navigation, the stable operation of various marine equipment is directly related to navigation safety and operational efficiency. Abnormal vibration of equipment is an important signal of potential malfunction. If it cannot be monitored and warned in time, it may lead to serious consequences such as equipment damage, power interruption or even shipwreck. Therefore, the reliability and monitoring accuracy of marine equipment abnormal vibration alarm devices are of great importance as key safety monitoring devices.

[0003] Currently, sensors and alarms are mainly installed by fixing with screws. For example, a Chinese patent with announcement number CN206019693U discloses a vibration sensor mounting base, which is connected to the device body by connecting bolts. The base is connected to the device body by spring washers, flat washers, through holes 2 and base 1, with a total of three connecting bolts. When connecting, the flat surface of the device body should be cleaned first, and each connecting bolt should be tightened evenly in stages to avoid uneven force.

[0004] The existing mounting bases mentioned above are cumbersome to disassemble and assemble, making it inconvenient to repair or replace the alarm. Furthermore, the mounting bases lack a waterproof structure, making them unsuitable for environments with water, such as ships, resulting in a limited range of applications. Therefore, this paper proposes a mounting base for a marine equipment abnormal vibration alarm to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, such as cumbersome disassembly and assembly, inconvenience in repairing and replacing alarms, inconvenience in use, lack of waterproof structure, and thus limited applicability, this utility model proposes a mounting base for a marine equipment abnormal vibration alarm.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The mounting base of the abnormal vibration alarm for marine equipment of this utility model includes a base body, an inner cavity is provided in the base body, a positioning component is provided in the inner cavity, a bidirectional lead screw is rotatably provided in the positioning component, and sliding plates are respectively threaded to the two ends of the bidirectional lead screw with opposite threads. Clamping plates are respectively fixed to the two sliding plates, and both clamping plates extend and are provided on the base body.

[0007] The base body is provided with a protective component, which includes an inner cylinder and an outer cylinder fixed to the base body. A rubber airbag ring is provided between the inner cylinder and the outer cylinder. A protective cover is threadedly connected to the outer wall of the inner cylinder. A compression ring plate for squeezing the rubber airbag ring is fixed to the outer wall of the bottom opening of the protective cover.

[0008] Both clamps are located inside the protective cover.

[0009] Preferably, the positioning component includes two guide grooves formed on the upper part of the base body, and both guide grooves are connected to the inner cavity. The two clamping plates pass through and slide in the two guide grooves, and the clamping plates are perpendicular to the guide grooves.

[0010] Preferably, the positioning assembly further includes two first-positioning rods that are laterally fixed in the inner cavity, and the two first-positioning rods are respectively arranged parallel to each other below the two guide grooves. The bidirectional lead screw is rotatably installed in the inner cavity and is parallel to the two first-positioning rods. The two sliding plates are respectively slidably arranged at both ends of the two first-positioning rods.

[0011] Preferably, one end of the bidirectional lead screw passes through the outside of the base body and is fixedly connected to a worm gear. A worm is provided below the worm gear and meshes with it for transmission. The worm is rotatably mounted on the outer wall of the base body, and one end of the rotation center axis of the worm is fixedly connected to a turntable.

[0012] Preferably, the inner cylinder is located inside the outer cylinder, and the protective component further includes multiple through holes evenly distributed on the base body, and the multiple through holes are arranged in a ring between the inner cylinder and the outer cylinder. A second limiting rod is slidably disposed through each of the through holes, and a first ring plate is fixedly connected to the top of the multiple second limiting rods. A sliding ring is rotatably installed on the first ring plate, and the rubber airbag ring is fixed on the sliding ring.

[0013] Preferably, all the through holes are connected to the inner cavity, the first ring plate and the sliding ring are located between the inner cylinder and the outer cylinder, and the bottom ends of the multiple second limiting rods are fixed to the second ring plate, and the second ring plate is located inside the inner cavity.

[0014] Preferably, each of the second limiting rods is fitted with a spring, and the spring is located between the first ring plate and the base body.

[0015] Preferably, the base body has multiple fixing ears fixed to its bottom side, and all fixing ears are fastened to external components by bolts.

[0016] The advantages of this utility model are:

[0017] 1. This utility model allows the alarm device located inside the inner cylinder to be removed by unscrewing the protective cover from the inner cylinder. At this time, under the action of the spring, the No. 2 ring plate and the rubber airbag ring will reset, and the liquid rubber airbag ring will shrink back. Then, the turntable is rotated in the opposite direction to expand the two clamps outward, which makes the alarm device located inside the inner cylinder easier to remove. Compared with the traditional mounting base, the disassembly and assembly speed is faster and the use is more convenient.

[0018] 2. This utility model uses a compression ring plate to gradually compress the rubber airbag ring downwards. Under the reaction force of the spring, both the sliding ring and the compression ring plate exert a compression effect on the rubber airbag ring, thereby increasing the deformation of the rubber airbag ring. The deformed rubber airbag ring then seals and fills the space between the inner and outer cylinders, as well as between the compression ring plate and the sliding ring, thus achieving a sealing effect. Furthermore, the protective cover effectively reduces the risk of damage to the alarm due to impacts, resulting in better protection. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Please see Figure 1-5 As shown, a mounting base for a marine equipment abnormal vibration alarm includes a base body 1. The base body 1 has an inner cavity 12. The inner cavity 12 has a positioning component 2. A bidirectional lead screw 25 is rotatably mounted in the positioning component 2. The two ends of the bidirectional lead screw 25 with opposite threads are respectively threaded to sliding plates 23. Clamping plates 24 are respectively fixed to the two sliding plates 23, and both clamping plates 24 extend onto the base body 1.

[0030] The base body 1 is provided with a protective component 3. The protective component 3 includes an inner cylinder 31 and an outer cylinder 32 fixedly connected to the base body 1. A rubber airbag ring 37 is provided between the inner cylinder 31 and the outer cylinder 32. A protective cover 310 is threadedly connected to the outer wall of the inner cylinder 31. A compression ring plate 311 for compressing the rubber airbag ring 37 is fixedly connected to the outer wall of the bottom opening of the protective cover 310.

[0031] Both clamps 24 are located inside the protective cover 310.

[0032] The positioning component 2 includes two guide grooves 21 formed on the upper part of the base body 1, and both guide grooves 21 are connected to the inner cavity 12. Two clamping plates 24 are slidably disposed in the two guide grooves 21, and the clamping plates 24 are perpendicular to the guide grooves 21.

[0033] The positioning component 2 also includes two first limiting rods 22 that are laterally fixed in the inner cavity 12, and the two first limiting rods 22 are respectively arranged parallel to each other below the two guide grooves 21. The bidirectional lead screw 25 is rotatably installed in the inner cavity 12 and is parallel to the two first limiting rods 22. The two sliding plates 23 are respectively slidably arranged at both ends of the two first limiting rods 22.

[0034] One end of the bidirectional lead screw 25 passes through the outside of the base body 1 and is fixedly connected to a worm gear 26. A worm 27 is provided below the worm gear 26 and is meshed and connected to it. The worm 27 is rotatably mounted on the outer wall of the base body 1. One end of the rotation center axis of the worm 27 is fixedly connected to a turntable 28.

[0035] The inner cylinder 31 is located inside the outer cylinder 32. The protective component 3 also includes a plurality of through holes 33 evenly distributed on the base body 1, and the plurality of through holes 33 are arranged in a ring between the inner cylinder 31 and the outer cylinder 32. A second limiting rod 34 is slidably disposed through each of the through holes 33. The top ends of the plurality of second limiting rods 34 are fixedly connected to a first ring plate 35. A sliding ring 36 is rotatably installed on the first ring plate 35, and the rubber airbag ring 37 is fixed on the sliding ring 36.

[0036] All through holes 33 are connected to the inner cavity 12. The first ring plate 35 and the sliding ring 36 are located between the inner cylinder 31 and the outer cylinder 32. The bottom ends of multiple second limiting rods 34 are fixed to the second ring plate 39, and the second ring plate 39 is located inside the inner cavity 12.

[0037] Each of the second limiting rods 34 is fitted with a spring 38, and the spring 38 is located between the first ring plate 35 and the base body 1.

[0038] The base body 1 has multiple fixing ears 11 fixed to its bottom side, and all fixing ears 11 are fastened to external components by bolts.

[0039] During operation, the existing mounting base is cumbersome to disassemble and assemble, making it inconvenient to inspect or replace the alarm. In addition, the mounting base lacks a waterproof structure, making it unsuitable for environments with water, such as ships, resulting in a limited range of applications. In this solution, in the initial state, the spring 38 will always push the first ring plate 35 upward, so that the second limiting rod 34 extends to the top of the base body 1, and the second ring plate 39 fits against the top of the inner cavity 12, thereby limiting the lifting height of the rubber airbag ring 37 between the inner cylinder 31 and the outer cylinder 32, thus achieving the limiting function.

[0040] In use, the alarm is placed between two clamping plates 24, and then the turntable 28 is rotated. When the turntable 28 rotates, it drives the worm wheel 26 to rotate through the worm 27, which in turn drives the bidirectional lead screw 25 to rotate in the inner cavity 12. Since the two ends of the bidirectional lead screw 25 have opposite patterns, and under the sliding limit of the two sliding plates 23 by the two first limit rods 22, when the bidirectional lead screw 25 rotates, it drives the two sliding plates 23 to slide inward or outward on the two first limit rods 22 at the same time. When the two sliding plates 23 move, they drive the two clamping plates 24 to clamp and fix the alarm located inside them, thereby achieving the function of fixing the alarm.

[0041] Then, the protective cover 310 is screwed onto the outside of the inner cylinder 31. At this time, with the protective cover 310 and the inner cylinder 31 fastened by the threads, the compression ring plate 311 on the protective cover 310 will gradually move between the inner cylinder 31 and the outer cylinder 32, and gradually squeeze the rubber airbag ring 37 downward. The rubber airbag ring 37 will deform after being compressed. As the compression ring plate 311 squeezes the rubber airbag ring 37, it will transmit the downward pressure to the spring 38, which will then compress and contract the spring 38. At this time, under the reaction force of the spring 38, both the sliding ring 36 and the compression ring plate 311 will squeeze the rubber airbag ring 37, thereby increasing the deformation of the rubber airbag ring 37. The deformed rubber airbag ring 37 will seal and fill the space between the inner cylinder 31 and the outer cylinder 32 and between the compression ring plate 311 and the sliding ring 36, thereby achieving a sealing effect. Under the protection of the protective cover 310, the damage to the alarm caused by impact can be effectively reduced, and the protection effect is better.

[0042] During disassembly, the protective cover 310 is unscrewed from the inner cylinder 31. At this time, under the action of the spring 38, the second ring plate 39 and the rubber airbag ring 37 will be reset, and the rubber airbag ring 37 will shrink back. Then, the turntable 28 is rotated in the opposite direction to expand the two clamps 24 outward, so that the alarm located inside can be removed. Compared with the traditional mounting base, the disassembly and assembly speed is faster and the use is more convenient.

[0043] This design allows for quick assembly and disassembly of the alarm, making it more convenient to use compared to traditional mounting bases. It also provides better protection, preventing water corrosion while protecting the alarm from impacts, thus effectively extending its lifespan.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
