Description

Technical Field

[0001] This utility model relates to the field of hydrological monitoring technology, and in particular to an automatic lifting and maintenance device for hydrological equipment. Background Technology

[0002] An Acoustic Doppler Current Profiler (ADCP) is a hydrological device widely used for measuring flow in rivers, lakes, and oceans. One application of ADCP is the mobile measurement method, often simply called a mobile ADCP. Mobile ADCPs are typically mounted on hydrological survey vessels or small floating hulls, measuring cross-sectional flow and velocity distribution by traversing the water surface. In this method, the ADCP dynamically measures as the survey vessel moves, shortening the measurement time and improving efficiency. Mobile ADCPs require regular maintenance. Before maintenance, they need to be retrieved from rivers, lakes, and oceans to shore or a vessel. Since there is no dedicated lifting device, currently, machines or manual labor are often used to tow the mobile ADCP ashore or to a vessel using ropes. This process can easily cause collision damage to the mobile ADCP. Utility Model Content

[0003] In view of this, the present invention proposes an automatic lifting and maintenance device for hydrological equipment, the purpose of which is to avoid damage to the mobile ADCP when it is retrieved for maintenance.

[0004] The technical solution of this utility model is implemented as follows:

[0005] An automatic lifting and maintenance device for hydrological equipment includes:

[0006] Fixed support;

[0007] A lifting frame is hinged to a fixed support about a horizontal axis. A guide rail for sliding hydrological equipment is formed on the lifting frame. The guide rail includes a first guide section and a second guide section distributed in sequence, with an included angle of 120°-150° between the first guide section and the second guide section. The lifting frame rotates about the horizontal axis to change the inclination of the guide rail.

[0008] The drive mechanism includes a rope winding shaft and a motor for driving the rope winding shaft to rotate. A rope is wound on the rope winding shaft and the rope is connected to the lifting frame.

[0009] As a further alternative, the lifting frame can rotate around the horizontal axis to form a first state or a second state; in the first state, the first guide section is horizontally positioned; in the second state, the second guide section is horizontally positioned.

[0010] As a further optional solution, the lifting frame is provided with multiple rollers, which form the bottom of the guide slide, and the multiple rollers are arranged at intervals along the length of the guide slide.

[0012] As a further optional solution, a support arm is provided below the lifting frame for abutting against the fixed support. When the support arm abuts against the fixed support, the lifting frame is in a first state.

[0013] As a further optional solution, a gantry support is also included, wherein the gantry support is fixed in position and the drive mechanism is mounted on the gantry support.

[0014] As a further alternative, the rope is connected to the end of the lifting frame away from the fixed support.

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] refer to Figure 1-3 An embodiment of this utility model shows an automatic lifting and maintenance device for hydrological equipment, including a fixed support 1, a lifting frame 2, and a drive mechanism 3;

[0030] The fixed support 1 is fixedly installed and can be fixedly installed on the hull, shore or other fixed structure; the lifting frame 2 is hinged to the fixed support 1 around a horizontal axis, and a guide slide 21 for the hydrological equipment to slide is formed on the lifting frame 2. The guide slide 21 includes a first guide section 21a and a second guide section 21b distributed in sequence, and an included angle K is formed between the first guide section 21a and the second guide section 21b, which is 120°-150°; the lifting frame 2 rotates around the horizontal axis to change the inclination of the guide slide 21; the driving mechanism 3 includes a rope shaft 21 and a motor 32 for driving the rope shaft 21 to rotate. A rope 33 is wound on the rope shaft 21 and the rope 33 is connected to the lifting frame 2.

[0031] Specifically, when the rope shaft 21 retracts the rope 33, the rope 33 pulls the lifting frame 2 to rotate and rise around the horizontal axis; when the rope shaft 21 releases the rope 33, the lifting frame 2 rotates and descends around the horizontal axis under its own weight; when it is necessary to retrieve the mobile ADCP 100, the first guide section 21a is lowered below the water surface, and then the mobile ADCP 100 is pulled into the first guide section 21a of the lifting frame 2. Then, the inclination of the lifting frame 2 is changed by the drive mechanism 3, causing the mobile ADCP 100 to slide along the guide slide 21. The mobile ADCP 100 slides from the first guide section 21a to the second guide section 21b, where workers can remove the mobile ADCP 100 from the second guide section 21b.

[0032] If the fixed support 1 is fixed to the shore, the traverse ADCP 100 can be pulled by a tow rope to the first guide section 21a of the lifting frame 2. Since the first guide section 21a is below the water surface, the traverse ADCP 100 will not collide with the lifting frame 2. If the fixed support 1 is fixed to the hull, the traverse ADCP 100 can be pulled by a tow rope, or the hull can be directly manipulated to meet the traverse ADCP 100, allowing it to enter the first guide section 21a. Compared to the prior art, the automatic lifting and maintenance device of this embodiment can prevent the traverse ADCP 100 from colliding or scraping with the hull or shore structure during recovery.

[0033] Specifically, the above scheme is as follows: Figure 2 and Figure 3As shown, the lifting frame 2 rotates around the horizontal axis to form a first state or a second state; in the first state, the first guide section 21a is horizontally positioned; in the second state, the second guide section 21b is horizontally positioned. Specifically, in the first state, the first guide section 21a should be below the horizontal plane to prevent the bottom of the mobile ADCP 100 from colliding with the first guide section 21a when the mobile ADCP 100 enters the guide slide 21.

[0034] In some embodiments, to further prevent damage to the mobile ADCP 100, such as Figure 1 As shown, the lifting frame 2 is equipped with multiple rollers 22, which form the bottom of the guide slide 21. The multiple rollers 22 are arranged at intervals along the length of the guide slide 21. The rollers 22 are rotatable, which can reduce the friction when the mobile ADCP 100 slides in the guide slide 21.

[0035] The second guide section 21b provides deceleration for the underway ADCP 100, preventing it from hurtling directly towards the hull / shore along the first guide section 21a. Furthermore, the sliding speed of the underway ADCP 100 in the guide rail 21 can be adjusted by controlling the release and retraction speed of the rope 33 and the rotation speed of the lifting gantry 2.

[0036] In some embodiments, to further improve the stability of the mobile ADCP 100 when sliding in the guide rail 21, such as... Figure 1 As shown, the lifting frame 2 is equipped with railings 23 on both sides of the guide slide 21. In this way, the railings 23 on both sides can prevent the mobile ADCP 100 from detaching from the lifting frame 2.

[0037] In some embodiments, to ensure that the lifting frame 2 can stably support the mobile ADCP 100, such as... Figure 1 and Figure 2 As shown, a support arm 24 is provided below the lifting frame 2 to abut against the fixed support 1. When the support arm 24 abuts against the fixed support 1, the lifting frame 2 is in a first state. Specifically, the support arm 24 is positioned below the second guide section 21b, and a triangular support structure is formed between the second guide section 21b, the support arm 24, and the fixed support 1, making the structure between the lifting frame 2 and the fixed support 1 more stable and reducing the load on the drive mechanism 3.

[0038] In some embodiments, to facilitate the drive mechanism 3 to pull the lifting frame 2 from a height, such as... Figure 1As shown, it also includes a gantry support 4, which is fixed in position, and the drive mechanism 3 is mounted on the gantry support 4. Furthermore, to reduce the load on the drive mechanism 3 when pulling the lifting frame 2, the rope 33 is connected to the end of the lifting frame 2 away from the fixed support 1. This increases the distance between the traction point and the horizontal axis, making the lever arm longer, thereby reducing the load on the drive mechanism 3.

[0039] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
