Technical Field

[0001] This utility model relates to the field of river management technology, specifically to a bottom sediment quantitative discharge device. Background Technology

[0002] Seabed sediment is the deposited material at the bottom of a water body, composed of mineral particles of various sizes, organic debris, and microbial communities. Its formation is closely related to water transport and deposition, biological activity, and geochemical processes. It is an important component of the river ecosystem, not only providing habitat for benthic organisms but also participating in the cycling of matter and energy flow in the water, playing a crucial role in maintaining the ecological balance of the river. Proper treatment of seabed sediment can transfer adsorbed nutrients and some pollutants out of the river, reducing the potential risk of endogenous pollution. Simultaneously, the microorganisms in the sediment come into full contact with wastewater during treatment, accelerating the degradation and transformation of pollutants and helping to improve the self-purification capacity of the water body.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 This utility model provides a technical solution:

[0029] A bottom sediment quantitative discharge device includes a support plate 1, two sets of floating plates 2 are fixedly installed on both sides of the bottom of the support plate 1, and an installation plate 3 is fixedly installed in the middle of the top of the support plate 1.

[0030] By setting up the support plate 1, a support platform can be provided for the upper structure of the entire device. By installing the float plate 2 on both sides of the bottom of the support plate 1, the buoyancy is used to make the entire device float on the water surface, which makes it easy to move the device to a designated location in the river channel, and provides convenience for subsequent treatment of the bottom sediment at the designated location. The top middle of the support plate 1 is fixed to install components such as the movable seat 6, providing a support point for the installation and rotation of the movable seat 6, ensuring that the movable seat 6 can be stably installed on the device and realize its corresponding functions.

[0031] It also includes a discharge hood 4, which is located below the floating plate 2. The top center of the discharge hood 4 is fixedly connected to one end of the lead screw 5. A movable seat 6 is installed on the surface of the lead screw 5. The movable seat 6 is rotatably connected to the middle of the mounting plate 3. A limit plate 10 is fixedly installed at the bottom of the movable seat 6. A limit groove 11 is opened in the middle of the mounting plate 3. The limit plate 10 and the limit groove 11 are slidably engaged. A first synchronous toothed wheel 12 is fixedly installed on the top of the movable seat 6. The first synchronous toothed wheel 12 is connected to the second synchronous toothed wheel 14 through a synchronous toothed belt 13. The bottom center of the second synchronous toothed wheel 14 is connected to the output end of the motor 15. The motor 15 is fixedly installed on the support plate 1. The top of the lead screw 5 is fixedly connected to the top plate 16. Two sets of guide rods 17 are provided on both sides of the lead screw 5. The top of the guide rods 17 is fixedly connected to the top plate 16. The bottom of the guide rods 17 is fixedly connected to the discharge hood 4. A sliding seat 18 is slidably installed on the surface of the guide rods 17. The sliding seat 18 is fixedly connected to both sides of the mounting plate 3.

[0032] By setting up the discharge hood 4, the bottom sediment area to be treated can be covered and relatively isolated from the surrounding water environment, so that the sludge pump 7 can quantitatively extract the bottom sediment inside the hood, avoiding interference with the bottom sediment in the surrounding non-target areas, reducing the impact on the living environment of benthic organisms, and protecting the balance and stability of the aquatic ecosystem. The output end of the motor 15 drives the moving seat 6 to rotate through the second synchronous toothed wheel 14, the synchronous toothed belt 13 and the first synchronous toothed wheel 12. Since the limiting plate 10 slides with the limiting groove 11 on the mounting plate 3, the rotating moving seat 6 drives the lead screw 5 to move up and down, thereby driving the discharge hood 4 to move up and down. The depth of the discharge hood 4 in the water can be adjusted according to actual needs to adapt to different bottom sediment treatment requirements. The guide rod 17 provides guidance for the up and down movement of the discharge hood 4, ensuring that the discharge hood 4 moves stably in the vertical direction.

[0033] It also includes a sludge pump 7, which is fixedly installed on the top side of the discharge hood 4. The sludge inlet of the sludge pump 7 is connected to the bottom of the discharge hood 4 through a connecting rigid pipe 8, and the sludge outlet of the sludge pump 7 is equipped with a connecting flexible hose 9.

[0034] By setting up the sludge pump 7, the bottom sediment in the discharge hood 4 can be extracted through the connecting rigid pipe 8 and transported to a designated location for treatment through the connecting flexible pipe 9, realizing the quantitative discharge of bottom sediment, effectively controlling the amount of bottom sediment to be treated, and reducing the impact on the ecological environment.

[0035] A vent pipe 19 is fixedly installed inside the guide rod 17. One end of the vent pipe 19 is connected to the inside of the exhaust hood 4, and the other end of the vent pipe 19 is located above the top of the guide rod 17.

[0036] By setting up the vent pipe 19, the air pressure inside and outside the discharge hood 4 can be balanced, avoiding the impact of air pressure changes inside the hood on the extraction effect of the bottom sediment or damage to the device during the up-and-down movement of the discharge hood 4 or the extraction of the bottom sediment, thus ensuring the normal operation of the device.

[0037] A water inlet groove 20 is provided on the other side of the top of the discharge hood 4. An installation groove 21 is provided on the outside of the water inlet groove 20. A sealing plate 22 is slidably installed in the installation groove 21. One side of the sealing plate 22 is fixedly connected to the telescopic end of the electric push rod 23. A waterproof box 24 is provided on the outside of the electric push rod 23. The telescopic end of the electric push rod 23 is slidably fitted with the waterproof box 24. The electric push rod 23 and the waterproof box 24 are fixedly connected to the top of the discharge hood 4.

[0038] By setting up the water inlet trough 20, when it is necessary to add water to the discharge hood 4 or adjust the water level, the water inlet trough 20 can be opened by pushing the sealing plate 22 with the electric push rod 23. Water can then enter the discharge hood 4 through the water inlet trough 20. When water is not needed, the electric push rod 23 drives the sealing plate 22 to seal the water inlet trough 20, preventing water from entering or flowing out of the discharge hood 4 at will. The water level in the discharge hood 4 can be adjusted according to the actual situation to better meet the needs of bottom sediment treatment. At the same time, the waterproof box 24 protects the electric push rod 23 from water corrosion and extends its service life.

[0039] In practical use, the device is moved to the designated location. First, the float plate 2 and support plate 1 are used to make the device float on the water surface. Then, an external vessel tows the device to the designated bottom sediment treatment area. The motor 15 is started, driving the second synchronous toothed wheel 14 to rotate. This rotation, via the synchronous toothed belt 13, causes the first synchronous toothed wheel 12 to rotate, which in turn causes the moving seat 6 to rotate on the lead screw 5. This causes the lead screw 5 to move downwards. Through the cooperation of the limiting plate 10 and the limiting groove 11, and the guide rod 17 and the sliding seat 18, the discharge hood 4 is stably adjusted. When the appropriate depth is reached, the discharge hood 4 covers the bottom sediment of the designated area. The sludge pump 7 extracts the bottom sediment from the bottom of the discharge hood 4 through the connecting rigid pipe 8 and transports it to the designated location through the connecting flexible hose 9. When the extraction reaches the final stage, the sealing plate 22 can be pushed by the electric push rod 23 to open the water inlet trough 20. Water enters the discharge hood 4 to dilute the bottom sediment remaining at the bottom, thereby facilitating extraction. During the process, the air pipe 19 inside the guide rod 17 balances the air pressure inside and outside the discharge hood 4, ensuring that the extraction work is carried out smoothly, thereby achieving quantitative discharge treatment of river bottom sediment.
