Abstract

This utility model relates to the field of river surface floating debris retrieval technology, and more particularly to an amphibious multi-grab retrieval device, comprising an external connecting part, a main grabbing part, an internal connecting part, and two side grabbing parts. This utility model connects to an underwater operating device via the external connecting part. By rationally setting the height of the main frame of the main grabbing part, a bucket with a certain depth is formed, increasing the amount of debris retrieved. The limitation of the claw bar structure improves the efficiency of debris fixation. The adjustable side grabbing parts allow for efficient and wide-area surface debris removal in mode one, and in mode two, for cleaning rivers with complex flow conditions or removing debris with a certain degree of mobility. The connecting part uses hinged bolts to enable the retrieval device to withstand greater loads. The connection between the perforated square tube and the C-shaped hinge clamp limits the opening and closing angle, making the retrieval device more reliable in operation.

Description

Technical Field

[0001] This utility model relates to the field of river surface floating object salvage technology, and in particular to an amphibious multi-grab salvage device. Background Technology

[0002] Floating debris pollution is the most obvious form of water pollution. Based on the nature of the floating debris itself, it can be divided into biodegradable and non-biodegradable floating debris pollution. Among them, biodegradable organic floating debris can evolve into aquatic plant pollution or biological pollution such as red tides over time, which greatly harms the river environment. Therefore, this type of pollution needs to be given special attention during the cleanup of rivers, lakes, and other waterways. Biodegradable floating debris should be removed in a timely manner to prevent further environmental degradation.

[0003] Chinese Patent Publication No. CN220644160U discloses a tool for retrieval of floating debris from river surfaces, including a support rod. First claw strips are fixed to the upper and lower surfaces of the support rod, and a curved rod is fixed to the outer end of the support rod. A second claw strip is fixed to the outer surface of the curved rod. By employing a transverse and longitudinal claw strip structure design, floating debris is retrieved through the claw strips, facilitating direct dumping and preventing material accumulation, thus making it more convenient to use.

[0004] The aforementioned tools for removing floating debris from the river surface have the following problems:

[0005] Without corresponding underwater operation equipment, it is difficult to thoroughly clean wider river channels;

[0006] The working surface is a planar structure, which limits its application to a single working environment. It is not effective in cleaning complex water flow conditions or when dealing with debris that has a certain degree of mobility.

[0007] The working surface is a planar structure, which limits the amount of debris that can be retrieved in a single operation, resulting in low work efficiency. Utility Model Content

[0008] Therefore, this utility model provides an amphibious multi-grab salvage device to overcome the problem of poor cleaning effect in the face of complex water flow conditions in the prior art.

[0009] To achieve the above objectives, this utility model provides an amphibious multi-grab salvage device, comprising:

[0010] An external connection part, which connects to an external underwater operating device;

[0011] The main gripping part is connected to the external connecting part;

[0012] The side gripper has two parts, each connected to the main gripper.

[0013] An internal connecting part, located between the main gripping part and the side gripping part, can limit the angle between the main gripping part and the side gripping part.

[0014] Furthermore, the external connecting part is provided with a hook-shaped support structure for supporting the weight of the entire salvage device, and also with a connecting hole structure for fixing the position of the salvage device.

[0015] Furthermore, the main gripping unit includes

[0016] The main frame is connected to the external connecting part and is provided with two main transverse main beams and several main longitudinal or diagonal auxiliary beams.

[0017] The main working claw is mounted on the main gripper transverse main beam located below the main frame;

[0018] The width of the main frame is 1 / 3 to 2 / 3 of the length of the main working claw.

[0019] Furthermore, the main working claw includes several first claw bars;

[0020] Each of the claw bars includes a vertical portion and a curved portion, with an included angle of 110° to 140° between the vertical portion and the curved portion.

[0021] Furthermore, the main frame is a planar trapezoidal structure, narrow at the top and wide at the bottom, with a thickness that is thicker in the middle and thinner at the sides.

[0022] Furthermore, the side gripping portion includes a left gripping portion and a right gripping portion, each side gripping portion including...

[0023] The side frame is connected to the main gripper and is provided with two transverse main side grippers and several longitudinal or oblique auxiliary side grippers. The width of the longitudinal or oblique auxiliary side grippers of the side frame is the same as the width of the longitudinal or oblique auxiliary side grippers of the main frame.

[0024] The side working claw is mounted on the side frame and located on the lower side gripping transverse main beam.

[0025] Furthermore, the side working claw includes several side claw strips of different lengths, which are arranged from the middle to both sides, and the length of the side claw strips gradually decreases.

[0026] Furthermore,

[0027] The lower end of the side gripping part is provided with a side gripping lug on the side gripping transverse main beam, which can be connected to a rope;

[0028] The main gripping part is provided with a main gripping lug on the upper end of the main gripping transverse main beam, which can be connected to a rope.

[0029] By adjusting the connection length of the rope, the angle between the side grip and the main grip can be limited.

[0030] Furthermore, the internal connection includes,

[0031] Bolts, specifically reamed hole bolts;

[0032] The nut is a hexagonal nut that can mate with the bolt;

[0033] A square tube with an opening is made by cutting a square slit in a complete square tube. The height of the slit is 2 / 3 of the original height of the square tube, and a hole is made near the edge of the slit.

[0034] The C-shaped hinge clamp is used to open a complete square tube, cut off the opposite two sides, and then widen the remaining two sides.

[0035] Furthermore,

[0036] The perforated square tube is located on the side of the main gripper transverse main beam at the lower end of the main gripper part, near the side gripper part;

[0037] The C-shaped hinged clamp with the opening is disposed on the side of the side grip transverse main beam at the lower end of the side grip part, near the main grip part.

[0038] The perforated square tube is connected to the C-shaped hinge clamp using bolts and nuts.

[0039] Compared with the prior art, the beneficial effects of this utility model are that the external connecting part ensures the strength of the connection between the salvage device and the underwater operation device through the support hook structure, and ensures the accuracy of the connection between the salvage device and the underwater operation device through the connecting hole. Furthermore, the underwater operation device allows for the cleaning of various locations in the river channel, eliminating cleaning dead spots.

[0040] Furthermore, the main gripping part, through the main frame structure that is thick in the middle and thin at both sides, ensures the overall strength of the retrieval device. By setting a reasonable height of the main frame, a bucket with a certain depth is formed, which increases the amount of debris that can be retrieved. By limiting the claw bar structure, the debris is effectively fixed, thereby improving efficiency.

[0041] Furthermore, the adjustable side grips can adapt to different working conditions. In mode one, it can clean up debris on the water surface over a large area with high efficiency. In mode two, it can still effectively clean the river channel when the water flow conditions are complex or when the debris has a certain degree of mobility.

[0042] Furthermore, the connecting part uses hinged hole bolts to enable the salvage device to withstand larger loads, and the connection between the perforated square tube and the C-shaped hinge clamp limits the opening and closing angle, making the salvage device more reliable in operation.

[0055] This utility model provides an amphibious multi-grab salvage device, including...

[0056] External connection part 22, which is connected to an external underwater operating device;

[0057] The main gripper 2 is connected to the external connecting part 22;

[0058] The side gripper 1 has two parts, and each part is connected to the main gripper 2.

[0059] The internal connecting part 4, which is located between the main gripping part 2 and the side gripping part 1, can limit the angle between the main gripping part 2 and the side gripping part 1.

[0060] Specifically, the external connection part 22 is set on the main gripping part 2. It is made of sheet metal by cutting and welding. The upper part is a hook-shaped support structure to support the weight of the salvage device, and the lower part is a connection hole structure to fix the salvage device to the connection platform of the underwater operation device. During connection, the strength of the connection is ensured by the support hook structure, and the accuracy of the connection is ensured by the connection hole.

[0061] Specifically, the main gripping unit 2 includes

[0062] The main frame, used to connect the various parts of the salvage device, is constructed by welding square tubing and sheet metal. Specifically, it includes two main gripping transverse beams, namely the upper main gripping transverse beam 23 and the lower main gripping transverse beam 24, and several main gripping auxiliary beams. The overall structure is planar, with a thicker middle and thinner sides, designed to prevent breakage caused by bending stress exceeding the stress limit of the parts. The height of the main frame is approximately half the width of the main working claw, ensuring that the main gripping part 2 can maximize the retrieval of debris from the water and clean the river channel when the angle is raised, while using minimal materials. This ensures both work efficiency and cost control.

[0063] The main working claw consists of multiple first claw strips 21 of fixed length. The claw strips are formed by bending metal cylinders and are divided into two parts: a vertical part 211 and a bent part 212. The vertical part 211 is used to filter out and pick up the debris. The bent part is at the end of the vertical part 211 and is integrally formed with the vertical part 211. The bending angle of the bent part is between 110° and 140°, which does not affect the entry of debris into the main gripper 2 and can effectively fix the debris that enters the main gripper 2. It is mainly used to hook the debris that may be thrown out during the lifting of the main gripper 2 to ensure the working efficiency of the main gripper 2.

[0064] In this embodiment, there are 9 claw bars.

[0065] The lifting lug 44 is located on the upper end of the main horizontal beam of the main frame, with one on each side, and is a ring structure.

[0066] Specifically, the two gripping parts 1 include

[0067] Both the left and right gripping parts, and the gripping part 1 on either side, include

[0068] The side frame, used to connect the various parts of the salvage device, is constructed from square tubing and sheet metal welded together. Specifically, it includes two side-grip transverse main beams, namely an upper side-grip transverse main beam 14 and a lower side-grip transverse main beam 15, and several side-grip auxiliary beams. The overall structure is a slightly backward-inclined trapezoidal structure with a certain slope, used to fit against the inclined surface at the rear end of the main frame when changing the working mode, so that the bucket formed by the salvage device in both working modes can maintain a certain degree of tightness, without producing excessive gaps, and ensuring efficiency.

[0069] Side working jaws,

[0070] It consists of three claw bars of different lengths: two second claw bars (13), one third claw bar (12), and one fourth claw bar (11), for a total of four. The length of the claw bars gradually decreases from the second to the fourth claw bars, with the longest claw bar being shorter than the first claw bar (21). The claw bars are arranged from the inside out, with the second to the fourth claw bars arranged sequentially. The claw bar includes two parts: a vertical part 211 and a bent part 212. The vertical part 211 is a vertical thin cylinder, and the bent part is at the end of the vertical part 211 and is integrally formed with the vertical part 211. The bending angle of the bent part is between 110° and 140°. In the first working mode, the vertical part 211 and the bent part have the same function as the main working claw. In the second working mode, the working claws on both sides are raised, which drives the side claw bar to stand up. Since the length of the claw bar gradually decreases from the middle to both ends, it will form an approximately straight inclined side, forming a bucket with sealed sides. The vertical part 211 and the bent part of the side claw bar on both sides work together to prevent debris from rolling out of the bucket.

[0071] The lifting lug 45 is also provided in the middle of the lower crossbeam of the two side frames, with one lug on each side frame.

[0072] The lifting lugs are connected by ropes, which can be used to control the angle between the main gripping part 2 and the side gripping part 1. This allows for detachment while ensuring the stability of the side gripping parts 1 during the second working mode of the retrieval device.

[0073] Specifically, the internal connection part 4 includes

[0074] Bolt 43, nut, perforated square tube 41, and C-shaped hinge clamp 42 are included. The bolt is a reamed bolt, which can withstand a large radial load. The nut is a hexagonal nut, which can cooperate with the reamed bolt. The perforated square tube is part of the main frame and is set at both ends of the main grab transverse beam at the lower end of the main frame. It is used to limit the range of motion of the C-shaped hinge clamp, restricting the range of motion of the C-shaped hinge clamp to a range of 90 degrees, ensuring the reliability of the salvage device, improving the load-bearing capacity of the two grab parts 1 in the first working mode, and ensuring that the two grab parts 1 can be fixed in the first working mode position with sufficient strength. The C-shaped hinge clip is positioned near the main frame on the side-grabbing transverse main beam. It is used to widen the C-shaped hinge clip, which is collinear with the cut square tube with the opening, to become the outer layer, so that the two transverse main beams can be connected collinearly. The C-shaped hinge clip design simplifies the alignment and fixing process, and simplifies the installation process. The hinge design allows for a certain angle adjustment to meet the requirements of mode transformation. The outer nested design enhances the strength and rigidity of the connection part and ensures structural stability.

[0075] Working principle: This utility model has two working modes. Figures 1 to 6The view shown is of the first working mode of the amphibious multi-grab salvage device. The first working mode is used to clean up debris on calm water or non-flowing debris (such as aquatic plants). The two grabs 1 are opened to form a bucket-shaped space with open sides. The salvage device is angled slightly downward. The underwater operation device propels the salvage device forward, and the debris enters the salvage device. When the device is almost full of debris, it is lifted upward to retrieve the debris and unload it at a designated location. Figure 7 The view shown is of the second working mode of the amphibious multi-grab retrieval device. The second working mode is used to clean up water surfaces with complex currents or debris with a certain degree of mobility (such as balls, water bottles, etc.). The two grabs 1 are retracted to form a bucket-shaped space sealed on both sides. The angle of the retrieval device is slightly downward. When the underwater working device moves forward, the debris can only enter the bucket from the front, and the claw strips on both sides of the bucket prevent the debris from flowing out, so that the debris accumulates in the bucket. When the bucket is full, the retrieval device is raised and unloaded at the designated location.

[0076] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.

[0077] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
