Description

Technical Field

[0001] The present invention relates to the field of river and lake sediment restoration, and in particular to a sediment locking agent delivery device for river and lake ecological restoration projects. Background Art

[0002] As we all know, river and lake sediments are an important component of aquatic ecosystems, carrying a rich variety of aquatic organisms and organic matter. With the acceleration of industrialization, the intensification of agricultural production, and the pollution emissions brought about by urbanization, river and lake sediments have gradually become polluted, becoming a gathering place for pollutants such as heavy metals, persistent organic pollutants, and nutrients. These pollutants not only affect the ecological balance of water bodies but also pose a threat to drinking water safety and human health.

[0003] Sediment lock agent is a common one. It is put into polluted areas of rivers and lakes. It naturally settles to the bottom of rivers and lakes, reacts with sediments, locks pollutants in the sediments, and achieves the effect of ecological restoration.

[0004] However, the most common method of releasing sediment locking agents is to use mobile boats on the water, such as unmanned boats or manned boats, which carry the sediment locking agents and then directly release them into the water body through a hopper-like structure. However, this simple release equipment is prone to uneven release, affecting the effect of ecological restoration, and the release density is difficult to control for waters with different degrees of pollution.

[0044] The following description is merely illustrative in nature and is not intended to limit the present disclosure, its applications, or uses. It should be understood that throughout the drawings, identical or similar reference numerals indicate identical or similar parts and features. The drawings merely schematically illustrate the concepts and principles of the embodiments of the present disclosure and do not necessarily depict the specific dimensions and proportions of the various embodiments of the present disclosure. Certain portions of certain drawings may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure.

[0045] Example 1

[0046] like Figure 1 As shown: This embodiment provides a technical solution: a sediment locking agent delivery device for river and lake ecological restoration projects, comprising a delivery device 1, which is arranged on a water hull and is used to hold a solid granular sediment locking agent. The delivery device 1 adopts a funnel-shaped structure with a large upper opening and a small lower opening. A delivery port 15 is provided at the bottom of the delivery device 1 along the length direction, and a quantitative feeding component 8 is provided in the delivery port 15; wherein, the quantitative feeding component 8 includes a main shaft 80 and a partition 81, the main shaft 80 is rotatably installed along the length direction of the delivery port 15, a plurality of partitions 81 are provided, and are distributed in a circular array on the outer wall of the main shaft 80 along the length direction, a plurality of spaces capable of accommodating a fixed volume of sediment locking agent are formed between the plurality of partitions 81 and the inner wall of the delivery port 15, and a drive motor 5 transmission-connected to the main shaft 80 is installed at one end of the delivery device 1;

[0047] Working principle: When the device is in use, the delivery device 1 is installed at the front or rear end of the water hull, and then a variety of solid granular sediment lock agents are directly poured into the delivery device 1, and then the ship is sailed at a constant speed. During the sailing process, the driving motor 5 rotates, driving the main shaft 80 to rotate, and then under the action of the partition 81, the sediment lock agent is continuously delivered into the water body. The device is based on the solid granular sediment lock agent and adopts a quantitative feeding component 8 to control the delivery. The delivery speed of the quantitative feeding component 8 can be directly controlled by controlling the speed of the driving motor 5, so it is easy to control. Moreover, when the quantitative feeding component 8 is delivered again, since the size of the space formed by each two adjacent partitions 81 and the inner wall of the delivery port 15 is fixed, the delivery density of the sediment lock agent is directly related to the speed of the driving motor 5. Based on this, the device can also control the delivery density of the sediment lock agent according to the degree of sediment pollution in the water body by controlling the speed of the driving motor 5, thereby improving the applicability of the device.

[0048] Specifically, such as Figure 1 - Figure 8As shown, since most of the sediment locking agents are not of a single type, multiple sediment locking agents need to be mixed and stirred before being released, which undoubtedly increases the workload and equipment cost. Based on this, in this embodiment, one or more mixing components 4 are installed inside the delivery device 1, and the mixing component 4 includes a mixing shaft 40 and a mixing blade 41, wherein the mixing shaft 40 is rotatably installed inside the delivery device 1 along the length direction, and the mixing blade 41 is installed on the mixing shaft 40. When the mixing shaft 40 rotates, it can drive the mixing blade 41 to rotate, thereby mixing and stirring the multiple sediment locking agents inside the delivery device 1, which can reduce the investment cost of the equipment and improve efficiency at the same time.

[0049] Specifically, such as 1- Figure 8 As shown, in order to further reduce the cost of ecological restoration, in this embodiment, a linkage box 11 is installed on one side of the delivery device 1, and a first linkage control mechanism 6 is installed in the linkage box 11. The mixing shaft 40 is connected to the main shaft 80 through the first linkage control mechanism 6. The working principle is: when the main shaft 80 rotates under the drive control of the drive motor 5, the mixing shaft 40 can rotate synchronously with it, so as to achieve the effect of stirring and mixing the various bottom mud locking agents in the delivery device 1 while feeding. Therefore, the mixing does not require additional electronic control equipment for control, which reduces the equipment cost.

[0050] Specifically, such as Figure 1 - Figure 8 As shown, in order to realize the transmission connection between the multiple mixing shafts 40 and the main shaft 80, in this embodiment, the first linkage control mechanism 6 includes a main transmission wheel 60 and a slave transmission wheel 62, wherein the main transmission wheel 60 is installed in the linkage box 11 and is connected to one end of the main shaft 80, and the slave transmission wheel 62 is installed in the linkage box 11 and is connected to one end of the mixing shaft 40;

[0051] The main transmission wheel 60 and the slave transmission wheel 62 are connected via a transmission belt 61.

[0052] Working principle: When the main shaft 80 rotates under the drive control of the drive motor 5, the main transmission wheel 60 rotates, and through the transmission action of the transmission belt 61, the slave transmission wheel 62 rotates, so that the mixing shaft 40 rotates synchronously, achieving the effect of linkage mixing. It should be noted that the speed ratio of the mixing shaft 40 and the main shaft 80 can be adjusted by adjusting the diameter ratio of the main transmission wheel 60 and the slave transmission wheel 62.

[0053] Specifically, such as Figure 8 - Figure 11As shown, since the sediment locking agent is in granular form, it is easy to stick to each other after long-term storage, especially in an environment with heavy moisture, this situation is more common, which will directly affect the delivery. In order to solve this problem, in this embodiment, a vibration material component 3 is installed inside the delivery device 1 above the delivery port 15. The vibration material component 3 adopts a funnel-shaped structure that is compatible with the interior of the delivery device 1, and the vibration material component 3 can vibrate back and forth along the length direction of the delivery device 1 to achieve the vibration effect, which can effectively reduce the agglomeration of the sediment locking agent and ensure the efficient and smooth delivery of the sediment locking agent.

[0054] Specifically, such as Figure 8 - Figure 11 As shown, in order to ensure the lateral stability of the vibration frame 33 during vibration, a limiting strip 32 is provided on the side of the vibration frame 33 along the length direction, and the inner wall of the feeding device 1 is provided with a limiting groove 16 adapted thereto along the length direction. The limiting strip 32 slides and engages with the limiting groove 16, thereby making the lateral stability of the vibration frame 33 higher during vibration. It should be noted that the limiting groove 16 adopts a downward inclined opening structure from the outside to the inside, which can reduce the situation of material jamming.

[0055] Specifically, such as Figure 8 - Figure 11 As shown, in order to achieve the vibration effect of the vibration component 3, in this embodiment, the vibration component 3 includes a vibration frame 33, a return spring 30 and a second linkage control mechanism 7, wherein the bottom of the vibration frame 33 is provided with a discharge port 31 adapted to the delivery port 15; one end of the return spring 30 is installed on the end face of the vibration frame 33, and the other end is installed on the inner wall of one end of the delivery device 1; the second linkage control mechanism 7 is installed in the linkage box 11, and is used to control the vibration frame 33 to vibrate back and forth to achieve vibration.

[0056] Specifically, such as Figure 2 - Figure 3 As shown, in order to reduce the control equipment and reduce the cost of ecological restoration, in this embodiment, the transmission belt 61 adopts a chain belt structure, the main transmission wheel 60 and the slave transmission wheel 62 both adopt a sprocket structure, and the second linkage control mechanism 7 includes a turntable shaft 75, a fixed seat 72, a piston shaft 71 and a traction rod 70, wherein,

[0057] The turntable shaft 75 is rotatably mounted inside the linkage box 11. A sprocket 73 is sleeved on the upper portion of the turntable shaft 75, and a turntable 74 is sleeved on the lower portion. The surface of the turntable 74 is provided with protrusions 740 distributed in an annular array. The sprocket 73 is meshed with the transmission belt 61 for transmission connection, so that the transmission belt 61 can drive the turntable shaft 75 to rotate.

[0058] The fixing seat 72 is fixedly installed inside the linkage box 11;

[0059] One end of the piston shaft 71 is fixedly mounted on one end of the vibration frame 33, and the other end extends to the interior of the linkage box 11;

[0060] The traction rod 70 is disposed within the linkage box 11. One end of the traction rod 70 is movably connected to the end of the piston shaft 71. The middle portion is rotatably connected to the fixed seat 72 via a rotating shaft. A second protrusion 701 is provided below the other end. The second protrusion 701 contacts the upper surface of the rotating disk 74, forming a lever structure for the traction rod 70.

[0061] Working principle: when the second convex portion 701 does not overlap with the convex portion 1 740 on the surface of the turntable 74, the return spring 30 on the vibration frame 33 is in a natural state. At this time, the vibration frame 33 is at one end close to the linkage box 11. When the second convex portion 701 overlaps with the convex portion 1 740 on the surface of the turntable 74, the return spring 30 on the vibration frame 33 is in a tensioned state. At this time, the vibration frame 33 is at one end away from the linkage box 11. Based on this, when the turntable 74 rotates under the linkage action of the sprocket 73 and the turntable shaft 75, the position of the convex portion 1 740 changes continuously. Therefore, the vibration frame 33 continuously reciprocates under the action of the traction rod 70 and the return spring 30 to achieve vibration. Such a structural setting makes it possible to achieve the vibration of the vibration frame 33 without adding a driving structure, which not only ensures the synchronization of the vibration effect and the feeding rhythm, but also reduces the overall cost of the equipment.

[0062] Specifically, such as Figure 7 As shown, considering that the traction rod 70 may get stuck at the end position of the piston shaft 71 when rotating, a waist groove 700 is opened at one end of the traction rod 70, and the traction rod 70 is movably connected to the piston shaft 71 by inserting a rotating shaft into the waist groove 700, and the length of the waist groove 700 is greater than the diameter of the rotating shaft. Therefore, when the traction rod 70 rotates, the rotating shaft can move in the waist groove 700, thereby avoiding getting stuck.

[0063] Example 2

[0064] like Figure 1 - Figure 3 As shown: This embodiment provides a technical solution: In order to realize the installation of the launching device 1, this embodiment also includes a carrying device 2, which is composed of a plurality of cross bars 22 and a plurality of connecting plates 23 welded together to form a frame structure that can fit with the bottom of the launching device 1. A fixing plate 20 is welded and fixed on one side of the carrying device 2. The fixing plate 20 is used to fix the carrying device 2 on the hull, and the launching device 1 is engaged on top of the carrying device 2.

[0065] Specifically, such as Figure 1 - Figure 3As shown, in order to ensure the stable connection between the delivery device 1 and the carrying device 2, in this embodiment, the side wall of the delivery device 1 is provided with a plurality of cross bar grooves 12 along the length direction. When the delivery device 1 is installed in the carrying device 2, the cross bar 22 on the carrying device 2 is engaged in the cross bar groove 12, thereby improving the installation stability of the delivery device 1.

[0066] Specifically, such as Figure 1 - Figure 3 As shown, in order to further improve the stability of the delivery device 1, in this embodiment, locking pieces 21 are welded at both ends of the supporting device 2, and locking pieces 13 are installed at positions corresponding to the locking pieces 21 at both ends of the delivery device 1. When the delivery device 1 is installed in the supporting device 2, the locking pieces 21 and 13 are attached to each other and fixedly connected by pins or bolts.

[0067] Specifically, such as Figure 1 - Figure 3 As shown, in order to prevent splashing water from entering the dosing device 1 during the dosing process, causing the bottom mud locking agent in the dosing device 1 to agglomerate, in this embodiment, a top cover 10 is rotatably installed on the top of the dosing device 1, and a dosing bucket 14 is installed at the bottom of the dosing device 1 at the position of the dosing port 15.
