[0020] In the present invention, a worker starts the sludge suction mechanism, and the sludge containing water is sucked into the dewatering mechanism by the sludge suction mechanism. The dewatering mechanism discharges most of the water in the sludge and leaves a small amount of water in the sludge. When the sludge is discharged into the mixing device, the dosing component adds heavy metal adsorbents, organic pollutant degradation agents, nutrient fixers and other agents to the sludge, and the mixing device is started to fully mix the sludge with the agents. The design of discharging most of the water in the sludge allows the mixing device to process more sludge and makes it easier to mix the agents with the sludge, without leaving most of the agents in the water unable to be fully mixed with the sludge, so as to centrally treat the heavy metals, organic pollutants and nutrients in the sludge.

The flow meter is used to monitor the flow rate of the bottom mud discharged from the mud outlet end of the water removal mechanism. When the control device and the water removal mechanism maintain normal frequency movement, if the flow meter detects that the flow rate of the bottom mud at the mud outlet end of the water removal mechanism becomes faster or slower, the controller is used to control and change the operating frequency of the control device and the water removal mechanism accordingly. When other parameters remain unchanged, when the flow rate of the bottom mud at the mud outlet end of the water removal mechanism becomes faster, it means that the water content in the bottom mud is high. Then the water content of the bottom mud is controlled by the water removal mechanism to reduce it. On the contrary, when the flow rate of the bottom mud at the mud outlet end of the water removal mechanism becomes slower, it means that the water content in the bottom mud is low. At this time, the water content of the bottom mud is controlled by the water removal mechanism to increase it, so that the water content of the bottom mud is always within an appropriate range, so as to facilitate mixing with the reagent and subsequent treatment.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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 of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in 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.

[0031] See also Figure 1-6 The present invention discloses a water body bottom mud repairing device, comprising a mud suction mechanism 1, a mud processing mechanism and a hull 18, wherein the hull 18 comprises a hull 1801 and a bracket 1802 installed on the hull 1801, and the repairing device is placed on the bracket 1802. Such a design enables the device to be flexibly moved with the hull 18 to different positions of the water body, and cooperate with the mud suction mechanism 1 to suck the bottom mud at different positions out of the water body.

[0032] In one embodiment, a water removal mechanism 2 is provided at the output end of the mud suction mechanism 1, and the water removal mechanism 2 is used to control the water content of the sludge discharged from the mud suction mechanism 1 to the water removal mechanism 2. A speed measuring mechanism 19 is provided at the mud outlet end of the water removal mechanism 2, and the speed measuring mechanism 19 is used to monitor the mud outlet speed of the mud outlet end of the water removal mechanism 2. A control device is provided on the water removal mechanism 2, and the control device is connected to the signal of the water removal mechanism 2 and the speed measuring mechanism 19, and is used to adjust the water removal capacity of the water removal mechanism 2. The mud treatment mechanism includes a dosing component 15 and a mixing device, and the mixing device is interconnected and arranged at the mud outlet end of the water removal mechanism 2. The dosing component 15 is used to add medicine to the mud when the mud is discharged from the water removal mechanism 2 to the inside of the mixing device, and the mixing device is used to stir and mix the mud and the agent therein. A discharge mechanism is provided at the output end of the mixing device, and the discharge mechanism is used to quantitatively discharge the mud after mixing with the agent.

[0033] In the specific implementation, the staff starts the sludge suction mechanism 1, and the sludge containing water is sucked into the water removal mechanism 2 by the sludge suction mechanism 1. The water removal mechanism 2 discharges most of the water in the sludge and leaves a small amount of water in the sludge. When the sludge is discharged into the mixing device, the dosing component 15 adds heavy metal adsorbents, organic pollutant degradation agents, nutrient fixers and other agents to the sludge, and the mixing device is started to fully mix the sludge and the agents. The design of discharging most of the water in the sludge will enable the mixing device to process more sludge and make it easier to use the drugs. The agent is mixed with the bottom mud, and most of the agent will not remain in the water and cannot be fully mixed with the bottom mud, which is used to centrally treat the heavy metals, organic pollutants and nutrients in the bottom mud; the bottom mud then enters the discharge mechanism, and the discharge mechanism can cooperate with the guide groove or guide pipe to transport the bottom mud to the water body or other corresponding positions, and further mix the bottom mud with the agent, thereby effectively enhancing the treatment efficiency of the bottom mud, realizing the efficient repair of the bottom mud in the water body nearby, and after the repair is completed, the bottom mud is discharged back to the water body or transferred to a designated location.

[0034] The speed measuring mechanism 19 mentioned above is composed of a flow meter and a controller, and the flow meter is connected to the controller signal. The flow meter is used to monitor the flow rate of the bottom mud discharged from the mud outlet end of the water removal mechanism 2. When the control device and the water removal mechanism 2 maintain normal frequency movement, if the flow meter detects that the flow rate of the bottom mud at the mud outlet end of the water removal mechanism 2 becomes faster or slower, the controller is used to control and change the operating frequency of the control device and the water removal mechanism 2 accordingly. When other parameters remain unchanged, when the flow rate of the bottom mud at the mud outlet end of the water removal mechanism 2 becomes faster, it means that the water content in the bottom mud is high. Then the water content of the bottom mud is controlled by the water removal mechanism 2 to reduce it. Conversely, when the flow rate of the bottom mud at the mud outlet end of the water removal mechanism 2 slows down, it means that the water content in the bottom mud is low. At this time, the water content of the bottom mud is controlled by the water removal mechanism 2 to increase it, so that the water content of the bottom mud is always within an appropriate range, so as to facilitate mixing with the reagent and subsequent treatment.

[0035] In one embodiment, the mud suction mechanism 1 includes a mud suction pump 101, a sleeve 102 installed at the input end of the mud suction pump 101 and connected to each other, and a mud suction pipe 103 installed in the sleeve 102 in a telescopic and slidable manner. A filter is installed at one end of the mud suction pipe 103 away from the mud suction pump 101, and the mud suction mechanism 1 also includes a lifting device.

[0036] In this design, the filter is used to prevent large-volume impurities from entering the sludge suction pipe 103 and affecting the normal operation of the sludge suction pump 101 and subsequent equipment. The lifting device can be a telescopic push rod, which is installed on the hull 18, and the moving end of the lifting device is used to drive and drive the sludge suction pipe 103 to move up and down, so that the device can absorb the bottom mud at different depths of the water body.

[0037] In one embodiment, the water removal mechanism 2 includes a water squeezing cylinder 201 installed at the output end of the sludge suction pump 101 and connected to each other. The water squeezing cylinder 201 is arranged horizontally. The water squeezing cylinder 201 consists of a cylindrical barrel section and a gradient section whose diameter gradually decreases from left to right. A water squeezing auger 202 is rotatably installed in the water squeezing cylinder 201. The control device is used to drive the water squeezing auger 202 to rotate and adjust the speed of the water squeezing auger 202. The outer diameter of the water squeezing auger 202 changes synchronously with the inner diameter of the water squeezing cylinder 201, and the blade spacing of the water squeezing auger 202 changes from left to right according to the rotation of the water squeezing auger 202. The water volume of the water-squeezing cylinder 201 is reduced again. The gradient section of the water-squeezing cylinder 201 is composed of a water-filtering assembly 203. A drainage box 204 is provided on the outer side of the water-filtering assembly 203. A drainage port 205 is provided at the bottom of the drainage box 204. The water-squeezing auger 202 cooperates with the water-squeezing cylinder 201 to transport the bottom mud to the side away from the mud suction mechanism 1 while the water contained therein passes through the water-filtering assembly 203 and flows into the drainage box 204. A water-control assembly is slidably provided on the drainage box 204. The water-control assembly changes the water-filtering capacity of the water-filtering assembly 203 by sliding to block the water-filtering assembly 203.

[0038] Specifically, the water filter component 203 mentioned above can be detachably installed at the corresponding gradient section of the water squeezing cylinder 201. The water filter component 203 includes a filter frame with filter holes and a filter cloth arranged on the filter frame. When the water squeezing auger 202 rotates, it transports the bottom mud to the mud outlet end of the water squeezing cylinder 201 while squeezing the bottom mud. The moisture in the bottom mud passes through the water filter component 203 and flows into the drainage box 204, and flows out of the drainage box 204 through the drainage port 205.

[0039] In one embodiment, a water filtering assembly 203 is embedded in the interior of a drainage box 204 corresponding to the body section of the water squeezing cylinder 201, and the water control assembly includes a shielding sleeve 206 disposed in the drainage box 204, and an electric push rod 207 for driving the shielding sleeve 206 to move is installed on the drainage box 204. When the shielding sleeve 206 is not moving, it is located at the gradient section of the water squeezing cylinder 201, and it will not block the water filtering assembly 203 at the gradient section. The electric push rod 207 is used to drive the shielding sleeve 206 to approach and block the water filtering assembly 203 at the body section of the water squeezing cylinder 201, so that the water control assembly can slide laterally and block different numbers of filter holes on the water filtering assembly 203 at the body section of the water squeezing cylinder 201, thereby changing the amount of water in the bottom mud that passes through the water filtering assembly 203.

[0040] With this design, the electric push rod 207 is started to cause its moving end to telescope, thereby driving the shielding sleeve 206 to move accordingly on the water squeezing cylinder 201 and shield different numbers of filter holes in the water filtering assembly 203 at the barrel section of the water squeezing cylinder 201, thereby changing the water content of the bottom mud.

[0041] In one embodiment, the mixing device includes a shell 4 installed at the mud discharge end of the water squeezing cylinder 201, a stirring rod 5 rotatably installed in the shell 4, two discharge plates 7 rotatably installed at the bottom of the shell 4, and a driving device for driving the two discharge plates 7 to rotate. The control device includes a first motor 3, which is a dual-axis motor. Its first moving end is used to drive the water squeezing auger 202 to rotate, and its second moving end is provided with a first transmission wheel group 6. The first transmission wheel group 6 consists of two transmission wheels and a transmission belt arranged on the two transmission wheels and matched therewith. The two transmission wheels are respectively installed on the second moving end of the first motor 3 and the stirring rod 5. The first motor 3 cooperates with the first transmission wheel group 6 to drive the stirring rod 5 to rotate, so as to stir the bottom mud and medicine inside the shell 4.

[0042] In a specific implementation, when the first motor 3 is started, the water squeezing auger 202 will rotate. At the same time, the first motor 3 cooperates with the first transmission wheel group 6 to make the stirring rod 5 rotate synchronously. The rotation of the stirring rod 5 stirs the bottom mud in the shell 4, so that the bottom mud and the medicine can be fully mixed.

[0043] In one embodiment, the driving device includes two second transmission wheel groups 8, each of which is composed of two transmission wheels and a transmission belt arranged on the two transmission wheels and cooperating therewith, wherein one of the transmission wheels is mounted on the rotating shaft of the corresponding discharge plate 7, and the other transmission wheel is rotatably mounted on the shell 4, and the two transmission wheels on the shell 4 are mounted with another rotating belt cooperating therewith, and a machine base 9 is mounted on the shell 4, and a second motor 10 for driving the corresponding transmission wheel to rotate is mounted on the machine base 9.

[0044] With this design, the second motor 10 can drive the two transmission wheels on the shell 4 to cooperate with another transmission belt to rotate one clockwise and the other counterclockwise, thereby cooperating with the two second transmission wheel groups 8 to enable each discharge plate 7 to rotate around the rotating connection with the shell 4. In the normal state, the discharge plate 7 is in a horizontal state, so that a small part of the sludge enters the discharge mechanism, is transported by the discharge mechanism and mixed with the medicine, while the remaining majority of the sludge is stirred by the stirring rod 5 to be mixed with the medicine. When the amount of sludge in the shell 4 is large, the two discharge plates 7 are driven to be inclined close to the top wall of the discharge mechanism, so that the mixed sludge on the lower side layer falls into the discharge mechanism.

[0045] In one embodiment, the dosing component 15 includes a dosing pump 1501 installed on the shell 4, the output end of the dosing pump 1501 is installed with a dosing nozzle 1503 connected to the mud outlet end of the water squeezing cylinder 201, and the input end of the dosing pump 1501 is provided with a dosing port 1502.

[0046] In this design, a container carrying a medicine is installed at the dosing port 1502. After the dosing pump 1501 is started, the medicine is sprayed from the container through the dosing nozzle 1503 to the mud outlet end of the water squeezing cylinder 201, so that the medicine initially enters the bottom mud.

[0047] In one embodiment, the discharge mechanism includes a conveying shell 11 installed at the discharge end of the shell 4, the top of the conveying shell 11 is open and connected to the interior of the shell 4, a conveying auger 12 is rotatably installed in the conveying shell 11, a third motor 13 is installed on the shell 4, and a third transmission wheel group 14 is provided at the moving end of the third motor 13. The third transmission wheel group 14 consists of two transmission wheels and a transmission belt arranged on the two transmission wheels and matched therewith. The two transmission wheels are respectively installed on the moving end of the third motor 13 and the conveying auger 12, the transmission belt is located in the side wall of the shell 4, the third motor 13 is connected to the speed measuring mechanism 19 by signal, a mud outlet is opened at the bottom of the conveying shell 11, and a discharge shell 16 connected to the mud outlet is provided at the bottom of the conveying shell 11, the bottom of the discharge shell 16 is open, and a drainage pipe 17 connected to the interior of the discharge shell 16 is installed at the corresponding drainage outlet 205 of the drainage box 204.

[0048] In a specific implementation, when the two discharge plates 7 rotate downward to an inclined state, they face the top wall of the conveying shell 11, and are used to guide the sludge on the discharge plates 7 into the conveying shell 11. When the two discharge plates 7 continue to rotate downward to a vertical state, the sludge remaining on the discharge plates 7 can directly fall into the discharge shell 16, so that the sludge in the shell 4 can be fully discharged in different ways after being fully mixed with the agent, and the squeezed water will flow into the discharge shell 16 through the drain pipe 17, and be discharged synchronously with the sludge. Since the third motor 13 is connected to the speed measuring mechanism 19 signal, the rotation speed of the conveying auger 12 can be adapted to the different water contents of the sludge.
