Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection dredging heads, in particular to an environmental protection dredging head with adjustable dredging depth. Background Art

[0002] As a key equipment specially used in dredging projects, the core function of the environmental protection dredging head is to go deep into the water to accurately excavate silt, sand and various substances. Then, these excavated materials are transported to designated locations through pipelines for subsequent processing and disposal.

[0003] Environmentally friendly dredging heads are usually carefully constructed of multiple parts, including excavation heads, conveying pipelines, and power systems. The shape and size of the excavation heads are carefully designed and tailored to different dredging needs to ensure that various materials on the bottom of the water can be efficiently excavated. The role of the conveying pipeline is crucial. It is responsible for accurately transporting the excavated materials to the designated location. In order to minimize the impact on the environment, pipeline transportation is usually adopted. This method is not only efficient, but also can effectively avoid pollution to the environment caused by material leakage.

[0004] The significant advantage of an environmentally friendly dredging head is that it can effectively excavate materials on the bottom of the water while significantly reducing the impact on the environment. This makes it have important application value in dredging rivers, lakes, ports and other waters. By using an environmentally friendly dredging head, the water can be kept unobstructed and clean, making a positive contribution to the protection of the ecological environment and the sustainable use of water resources.

[0005] In addition, environmentally friendly dredging heads can also be used to remove underwater obstacles, such as shipwrecks, reefs, etc. These obstacles not only affect the navigation safety of the waters, but may also pose a threat to the living environment of aquatic organisms. By using environmentally friendly dredging heads, these obstacles can be safely and effectively removed, thereby effectively ensuring the safety and ecological balance of the waters.

[0006] In short, as an advanced dredging equipment, the environmental protection dredging head plays an important role in environmental protection dredging projects. Its efficient excavation ability, low impact on the environment and wide range of applications make it an important tool for maintaining the ecological environment of water bodies and ensuring the sustainable use of water resources. With the continuous advancement and innovation of technology, it is believed that the environmental protection dredging head will play a more important role in future dredging projects and create a better ecological environment for mankind.

[0007] There is a significant problem in the actual use of existing environmental protection dredging heads, that is, it is not convenient to flexibly adjust the dredging depth. During dredging operations, due to the inability to accurately adjust the dredging depth according to specific needs, over-dredging or insufficient dredging may occur. Excessive dredging may cause unnecessary damage to the underwater ecological environment, while insufficient dredging cannot achieve the expected dredging effect, affecting the quality of the project. In addition, the inconvenience in adjusting the dredging depth may also increase the difficulty and risk of the operation. In some complex water environments, fine dredging operations are required based on factors such as water depth and underwater topography. If the dredging head cannot flexibly adjust the depth, the operator may need to take other measures to compensate, which undoubtedly increases the complexity and potential risks of the work.

[0008] In order to solve this problem, it is necessary to improve and optimize the existing environmental dredging head so that it can more conveniently adjust the dredging depth to meet the needs of different working conditions. This will help improve the efficiency and quality of dredging operations while reducing the impact on the environment. Utility Model Content

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 4 The utility model provides a technical solution: an environmentally friendly dredging head with adjustable dredging depth, comprising an environmentally friendly dredging cutter head 1, on which an adjustable mechanism 200 is installed.

[0030] In this embodiment, the adjustable mechanism 200 is a structure for accurately adjusting the dredging depth according to different working conditions.

[0031] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the adjustable mechanism 200 includes a telescopic component fixedly installed at the center of one side of the environmental protection dredging cutter head 1 and a fixed shell 202 installed on the side of the telescopic component away from the environmental protection dredging cutter head 1. A drive component is installed in the fixed shell 202, and a threaded rod 204 connected to the telescopic component is connected to the drive component. Two limit movable components in mirror symmetry are connected to the telescopic component.

[0032] It should be noted that the telescopic component includes a movable sleeve 2011 and a fixed sleeve 2012; one end of the movable sleeve 2011 is fixedly connected to the center of one side of the environmental dredging cutter head 1, and the inner side of the fixed sleeve 2012 and the outer side of the movable sleeve 2011 are slidably connected and slide in close proximity, so as to be able to accurately adjust the dredging depth according to different working conditions.

[0033] It can be understood that the drive assembly includes a protective housing 2031, a servo motor 2032, a worm 2033 and a worm wheel 2034; the outer side of the servo motor 2032 is fixedly mounted on the inner side of the protective housing 2031, one end of the worm 2033 is fixedly connected to the output shaft of the servo motor 2032, and the other end thereof passes through the fixed housing 202 and extends to the inner side wall of the fixed housing 202 and is rotatably connected to the fixed housing 202 through a bearing, one side of the worm wheel 2034 is fixedly connected to one end of the threaded rod 204, and the worm 2033 and the worm wheel 2034 are engaged with each other in order to stably drive the threaded rod 204 to rotate.

[0034] In addition, one end of the threaded rod 204 away from the worm gear 2034 passes through one side of the fixed sleeve 2012 and extends to the inner side of the movable sleeve 2011 and is threadedly connected to the movable sleeve 2011. This is so that when the threaded rod 204 rotates, it can drive the movable sleeve 2011 to move inside the fixed sleeve 2012 under the thrust of the thread rotation.

[0035] In this embodiment, the outer side of the threaded rod 204 is rotatably connected to the inner side of the fixed sleeve 2012 via a bearing in order to further improve the rotation stability of the threaded rod 204 .

[0036] It should also be noted that a limiting groove 206 for sliding of the limiting moving component is provided on one side of the fixed sleeve 2012, so as to increase the movement of the moving sleeve 2011 while limiting the moving distance of the moving sleeve 2011.

[0037] It should be further explained that the limiting moving assembly includes an adjusting moving block 2051, a fixed connecting block 2052 and a sliding rod 2053; one side of the adjusting moving block 2051 is fixedly installed on the outside of the moving sleeve 2011, and one side of the fixed connecting block 2052 is fixedly installed on the inner wall of the limiting groove 206 by bolts, and the two ends of the sliding rod 2053 are respectively fixedly connected on the opposite sides of the two fixed connecting blocks 2052. The inner side of the adjusting moving block 2051 is slidably connected to the outer side of the sliding rod 2053 and slides in close proximity. The outer side of the adjusting moving block 2051 is slidably connected to the inner side of the limiting groove 206 so that the operator can easily adjust the dredging depth through simple operations, thereby avoiding excessive or insufficient dredging and ensuring that the dredging operation achieves the expected results.

[0038] The working principle of the above embodiment is:

[0039] First, the operator needs to ensure that the equipment is in a safe state and check whether all components are working properly. Next, the operator can start the servo motor 2032. When the servo motor 2032 is started, it will drive the worm 2033 to start rotating. The rotational motion of the worm 2033 is transmitted to the worm wheel 2034 through meshing, causing the worm wheel 2034 to also start rotating. As the worm wheel 2034 rotates, the threaded rod 204 connected thereto will also rotate. Since the threaded rod 204 and the movable sleeve 2011 are threadedly connected, the rotation of the threaded rod 204 will push the movable sleeve 2011 to move inside the fixed sleeve 2012. During the movement of the movable sleeve 2011, the adjusting block 2051 will slide on the sliding rod 2053. The design purpose of 1 is to limit the moving distance of the mobile sleeve 2011 and prevent it from moving excessively. By adjusting the cooperation between the moving block 2051 and the sliding rod 2053, it can ensure that the mobile sleeve 2011 moves smoothly within the specified range, thereby achieving accurate dredging depth adjustment. The operator can determine whether the dredging depth has reached the expected requirement by observing the relevant indicators or measuring equipment. Once the dredging depth adjustment is completed, the operator can turn off the servo motor 2032 to keep the dredging head at the current dredging depth for dredging operations. During the entire operation process, the operator needs to pay close attention to the operation of the equipment to ensure that all components are working properly to avoid malfunctions or safety problems. At the same time, the operator also needs to reasonably adjust the dredging depth according to the actual situation to achieve the best dredging effect.

[0040] Compared with the existing technology: the environmental protection dredging head with adjustable dredging depth can accurately adjust the dredging depth according to different working conditions through the mutual cooperation between the adjustable mechanisms 200 on the environmental protection dredging cutter head 1. The operator can easily adjust the dredging depth through simple operations, thereby avoiding excessive or insufficient dredging, ensuring that the dredging operation achieves the expected effect, improving the quality of the project, and thus improving the efficiency and quality of the dredging operation, solving the problem that the existing environmental protection dredging head is not convenient for flexible adjustment of the dredging depth.

[0041] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing disclosed power connection technology and power supply provision are also common knowledge in this field, so this application will not go into details.
