Description

Technical Field

[0001] This utility model relates to the field of liquid level telemetry probe technology, and in particular to a protection device for a liquid level telemetry probe in a ship's cabin. Background Technology

[0002] Monitoring the liquid level in ship compartments (such as ballast water tanks, fuel oil tanks, fresh water tanks, etc.) is a key aspect of safe navigation and efficient operation of ships. The liquid level telemetry system collects liquid level data in real time through probes, providing crew members with information such as compartment water level and fuel oil inventory. The probes need to withstand the complex environment inside the compartments for a long time, so protective covers are installed on the probes for protection. However, protective covers are usually fixed to the probe with bolts. When the protective cover needs to be replaced, tools such as wrenches and screwdrivers are required to loosen and remove the bolts one by one, and then install the bolts of the new protective cover one by one. The operation is cumbersome, time-consuming and laborious. Therefore, we need to consider how to solve this problem. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a protective device for a ship compartment liquid level telemetry probe. It is equipped with a wedge block, a first spring and a stop rod, etc. The probe body is fixed and unlocked through inclined surface cooperation and elastic linkage. Furthermore, the protective cover is easy to disassemble and install, and can be replaced without the aid of external tools.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A protective device for a remote liquid level telemetry probe in a ship's compartment includes a probe body. A cable is fixedly connected to the upper end of the probe body. A movable sleeve is provided on the outer side wall of the probe body. A protective sleeve is provided on the outer side wall of the movable sleeve. Sliding grooves are provided on both inner walls of the protective sleeve. Two fixed plates are fixedly connected to the upper end of the protective sleeve. Two sliding rods slide through each of the two fixed plates. One end of each pair of mutually cooperating sliding rods is fixedly connected to a movable plate. Clamping plates are fixedly connected to opposite sides of the two movable plates. The two clamping plates cooperate with the cable. A limiting mechanism for limiting the probe body is provided in both sliding grooves.

[0005] Preferably, the limiting mechanism includes two sliders that are slidably connected to the inner wall of the corresponding groove, and wedge blocks are fixedly connected to the opposite sides of the two sliders. Limiting grooves that cooperate with the corresponding wedge blocks are opened on both sides of the probe body.

[0006] Preferably, the opposite sides of the two sliders are elastically connected to the inner wall of the corresponding groove through a first spring, and the upper end of the movable sleeve is fixedly connected to two abutments, the upper ends of the two abutments extending into the interior of the corresponding groove and cooperating with the corresponding wedge block.

[0007] Preferably, the protective sleeve has movable grooves on both sides of its side walls, and guide rods are fixedly connected between the inner top and inner bottom of the two movable grooves. Movable blocks are slidably connected to the outer walls of the two guide rods. The opposite ends of the two movable blocks are fixedly connected to the two side walls of the movable sleeve, and a second spring is sleeved on the outer wall of the two guide rods. The two ends of the two second springs are elastically connected to the upper end of the corresponding movable block and the inner top of the movable groove, respectively.

[0008] Preferably, a protective layer is provided on the opposite sides of both clamps, and both protective layers are made of rubber.

[0009] Preferably, a third spring is sleeved on the outer side wall of each sliding rod, and both ends of each third spring are elastically connected to the side wall of the corresponding fixed plate and the side wall of the moving plate, respectively. A limit plate is fixedly connected to the other end of each sliding rod.

[0010] Compared with the prior art, the advantages of this utility model are as follows: 1. The structure includes a slider, a wedge block, and a first spring. By inserting the wedge block into the limiting groove, the probe body is limited and fixed. In this way, the protective cover can be installed on the probe body for protection. The structure also includes a stop rod, a guide rod, and a moving block, which makes the removal and installation of the protective cover convenient and simple, and can be achieved without the need for external tools. 2. The structure includes a fixed plate, sliding rod, and movable plate. The cable is clamped and fixed by two clamps to prevent the connection between the cable and the probe body from loosening or breaking due to shaking. When the cable diameter changes, the elastic force of the third spring will automatically adjust to ensure the fixing effect while avoiding excessive tightness that could damage the cable insulation layer.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1-7 A protective device for a remote liquid level telemetry probe in a ship's cabin includes a probe body 1, a cable 2 fixedly connected to the upper end of the probe body 1, a movable sleeve 3 provided on the outer wall of the probe body 1, the detection end of the probe body 1 passing through the movable sleeve 3, a protective sleeve 4 provided on the outer wall of the movable sleeve 3, the cable 2 passing through the protective sleeve 4, and the protective sleeve 4 wrapping around the outside of the movable sleeve 3 to form a physical barrier, which can resist mechanical collisions, water flow impacts, or scratches from debris in the ship's cabin, preventing direct damage to the probe body 1. The inner walls of both sides of the protective sleeve 4 are provided with... The slide groove 5 has a limiting mechanism for limiting the probe body 1. The limiting mechanism includes two sliders 6 that are slidably connected to the inner wall of the corresponding slide groove 5. Wedge blocks 7 are fixedly connected to the opposite sides of the two sliders 6. Limiting grooves 8 that cooperate with the corresponding wedge blocks 7 are opened on both sides of the probe body 1. By embedding the wedge blocks 7 into the limiting grooves 8 of the probe body 1, the probe body 1 is stably fixed by using the inclined surface cooperation, preventing the probe body 1 from loosening or falling off in the moving sleeve 3, and ensuring the accurate position of the detection end. In this design, the opposing sides of the two sliders 6 are elastically connected to the inner wall of the corresponding groove 5 via a first spring 9. Two abutment rods 10 are fixedly connected to the upper end of the movable sleeve 3. The upper ends of both abutment rods 10 extend into the corresponding groove 5 and cooperate with the corresponding wedge blocks 7. The upper surfaces of both abutment rods 10 are arc-shaped and face the inclined surface of the wedge blocks 7. Movable grooves 11 are provided on both side walls of the protective sleeve 4. When the probe body 1 needs to be disassembled, the abutment rods 10 push the wedge blocks 7 upwards to compress the first spring 9, causing the wedge blocks 7 to disengage from the limiting groove 8, thus quickly unlocking the probe body. Body 1, easy to operate, guide rods 12 are fixedly connected between the inner top and inner bottom of the two movable slots 11, and movable blocks 13 are slidably connected to the outer walls of the two guide rods 12. The opposite ends of the two movable blocks 13 are fixedly connected to the two side walls of the movable sleeve 3 respectively. The outer walls of the two guide rods 12 are fitted with second springs 14. The two ends of the two second springs 14 are elastically connected to the upper end of the corresponding movable block 13 and the inner top of the movable slot 11 respectively. The upper end of the protective sleeve 4 is fixedly connected to two fixing plates 15, and two sliding rods 16 slide through the two fixing plates 15. Each pair of sliding rods 16 has a movable plate 17 fixedly connected to one end of each pair of sliding rods 16. A clamping plate 18 is fixedly connected to the opposite side of each movable plate 17. The clamping plates 18 cooperate with the cable 2. A protective layer is provided on the opposite side of each clamping plate 18. Both protective layers are made of rubber. The rubber protective layer on the inner side of the clamping plate 18 can adhere to the cable 2, providing friction to prevent the cable 2 from sliding and avoiding hard compression damage to the cable 2's outer sheath. This is suitable for cables 2 of different diameters. A third spring 19 is fitted onto the outer wall of each sliding rod 16. Both ends of each third spring 19 are elastically connected to the side wall of the corresponding fixed plate 15 and the side wall of the movable plate 17, respectively. The sliding rod 16 and the third spring 19 cooperate to absorb the pulling force of the cable 2 caused by the ship's swaying, preventing the cable 2 from breaking at the connection point (such as the connector) with the probe body 1 due to excessive force, thus ensuring the continuity of signal transmission. A limit plate 20 is fixedly connected to the other end of each sliding rod 16.

[0015] In this utility model, when the protective sleeve 4 needs to be installed, the entire assembly of the movable sleeve 3 and the protective sleeve 4 is fitted into the probe body 1. The wedge block 7 is pressed into the slide groove 5 by the probe body 1. At this time, the first spring 9 is in a compressed state until it is aligned with the limiting groove 8. Then, through the elastic action of the first spring 9, the wedge block 7 is pushed into the limiting groove 8 to achieve the limiting and fixing of the probe body 1. Through the inclined surface cooperation, the probe body 1 can be stably clamped in the movable sleeve 3 to ensure the accurate position of the detection end and avoid detection errors caused by shaking. When it is necessary to remove the protective sleeve 4, the movable sleeve 3 can be pushed upward, so that the movable block 13 slides along the guide rod 12 and compresses the second spring 14. The upward movement of the movable sleeve 3 will cause the upper end of the abutment rod 10 to contact the inclined surface of the wedge block 7. Since the upper end surface of the abutment rod 10 is an arc surface, it generates a horizontal component force on the wedge block 7 when it moves upward, pushing the wedge block 7 to move towards the side of the slide groove 5 and compressing the first spring 9, thereby causing the wedge block 7 to disengage from the limiting groove 8. At this time, the locking of the probe body 1 is released. After the limit is released, the entire assembly consisting of the movable sleeve 3 and the protective sleeve 4 can be pulled out downward along the detection end of the probe body 1. In this way, the protective sleeve 4 can be replaced without the aid of external tools.

[0016] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
