Description

Technical Field

[0001] This invention relates to the field of river environment restoration technology, specifically to an intelligent integrated device for the remediation and treatment of heavy metal pollution in riverbed sediment. Background Technology

[0002] With the acceleration of industrialization and urbanization, large amounts of wastewater containing heavy metals are discharged into rivers, leading to increasingly serious pollution problems of heavy metals (such as lead, cadmium, mercury, and arsenic) in river sediments. Traditional river sediment heavy metal pollution remediation technologies mainly suffer from the following problems, highlighting the urgent need to develop efficient, integrated, and intelligent remediation equipment. Furthermore, the sampling and analysis process is severely disconnected from the remediation operation process, resulting in low efficiency.

[0003] Chinese Patent Publication No. CN 202785919 U discloses a device for treating heavy metal-contaminated sediment from rivers and lakes, comprising a screening cylinder and a sludge dewatering machine. The upper part of the screening cylinder has a sediment inlet, and the bottom surface of the screening cylinder is connected to the feed inlet of the sludge dewatering machine. From top to bottom, the screening cylinder contains a crushed stone screening screen, a coarse sand screening screen, and a fine sand screening screen. The sides of the cylinder have discharge ports corresponding to the three screening screens. The mesh diameters of the crushed stone screening screen, coarse sand screening screen, and fine sand screening screen are 10mm, 2mm, and 0.5mm, respectively. The crushed stone screening screen, coarse sand screening screen, and fine sand screening screen are inclined within the screening cylinder. This invention directly grades the heavy metal-contaminated sediment from rivers and lakes dredged by chaff suction, eliminating the need for drying. The treatment cycle is short, and the screening process relies entirely on gravity, unlike typical solid screening processes. Furthermore, the high moisture content effectively prevents screen clogging, resulting in low treatment costs.

[0004] However, the above solution still has the following problems:

[0005] In existing technologies, the steps of sampling contaminated sediment, laboratory analysis, development of remediation plans, and on-site construction are separate. It usually requires sending sampling boats or personnel to the river to collect samples, and then sending them back to the laboratory for analysis. It takes several days or even weeks before a remediation plan can be developed and remediation equipment can be mobilized to the site. The process is lengthy and costly, and it cannot achieve rapid response and precise treatment of contaminated sites.

[0006] Currently, the only remediation methods used are ship-borne spraying or manual application of remediation agents. These methods result in uneven agent diffusion, poor penetration into deep sediments, and are greatly affected by water surface fluctuations. They also fail to achieve precise and uniform mixing of agents with contaminated sediments, leading to unstable remediation results and significant agent waste.

[0007] River restoration sites are usually located in the wild and lack a stable power supply. Existing equipment relies on diesel generators or long-distance external cables, which not only causes noise and environmental pollution, but also severely limits the range of movement and working time of the equipment, making it difficult to carry out large-scale and long-term continuous restoration operations, thus causing many inconveniences and failing to meet the needs of normal use.

[0008] Therefore, the present invention requires the design of an intelligent integrated device for the remediation and treatment of heavy metal pollution in riverbed sediments to solve the aforementioned problems. Summary of the Invention

[0020] In a preferred embodiment of the present invention, a second drive motor is fixedly connected to the top of the support platform and to the side of the conveying chamber away from the conveying pump.

[0054] In this design, buffer springs 49 are fitted between the pressure plate 44 and the bottom limiting plate 43 and on the outside of the fixing rod 42. A sliding rod 46 is installed at the bottom of the pressure plate 44 above the corresponding sampling pipe 47.

[0055] Please see Figures 1-7 The working principle of this invention is as follows:

[0056] The equipment is equipped with a mobile platform 1, a first side positioning plate 2, and a second side positioning plate 3. During use, the equipment is carried to the target river channel by the mobile platform 1.

[0057] First, the sampling mechanism operates as follows: the second electric telescopic rod 41 drives the pressure plate 44 to press down, pressing the bottom sediment into the sampling pipe 47 to complete the sampling. The sample can be used for rapid testing. The first electric telescopic rod 21 drives the entire fixed frame 4 to descend vertically along the first side positioning plate 2, so that the bottom limiting plate 43 contacts the riverbed sediment. The second electric telescopic rod 41 inside the fixed frame 4 is activated, pushing the push rod 45 and the pressure plate 44 to move downward along the fixed rod 42, squeezing the bottom sediment and causing part of it to enter the opening at the upper end of the sampling pipe 47. After being released, the pressure plate 44 is reset under the action of the buffer spring 49, and the bottom sediment sample squeezed into the sampling pipe is retained therein, completing the sampling.

[0058] Then the repair operation mechanism is activated: the scissor lift 16 raises the support platform 5 to a suitable height; the water pump 15 pumps water from the river to the conveying bin 62 to mix with the agent; the conveying pump 61 pumps the mixture into the discharge pipe 51 through the conveying pipe 64 and the rotary joint 63.

[0059] When light shines on the solar panel 33, the photosensitive material in the panel, such as silicon, absorbs the light energy, excites electrons and generates current. These currents are collected by the integrated circuit device 34 and converted into direct current. The charging controller 35 is used to manage the electrical energy generated by the solar panel 33 and regulate the voltage and current to ensure the safe charging of the battery. The energy storage compartment 31 is used for power storage and processing, thereby ensuring the power needs for outdoor operations.

[0060] The control chip is used to control the operation of the electrical control box 11, wireless transceiver 12, water pump 15, scissor lift 16, first electric telescopic pole 21, lighting equipment 22, infrared sensor 23, first drive motor 26, battery storage 31, solar panel 33, integrated circuit device 34, charging controller 35, second electric telescopic pole 41, second drive motor 58, conveying pump 61 and conveying hopper 62, realizing unified management of power equipment. The infrared sensor 23 measures environmental parameters, converts them into signals and sends them to the control chip. The control chip receives the signals and processes them, generating corresponding control signals according to the preset control algorithm.

[0061] A rotary joint 63 is installed at the connection between the discharge pipe 51 and the conveying pipe 64 and at the top of the support platform 5 to ensure that water can be discharged while rotating. The second drive motor 58 drives the discharge pipe 51 and the discharger 53 to rotate through belt drive, so as to achieve uniform spraying or injection of the agent on the horizontal surface. Throughout the process, the power supply is continuously provided by the solar panel 33, and the control chip manages all the execution components in a unified manner.

[0062] The lighting equipment 22 provides on-site auxiliary lighting to meet the needs of different scenarios, and the infrared sensor 23 facilitates remote monitoring and processing.

[0063] For sampling: Infrared sensor 23 and lighting device 22 are used to assist in locating the sampling point;

[0064] For underwater rotation: the discharger 53 rotates at a low speed, mainly to achieve fan-shaped diffusion, and the second drive motor 58 has sufficient torque;

[0065] Regarding power supply: The battery storage compartment 31 has sufficient capacity to support the equipment to work continuously for a certain period of time, such as 24 hours, without sunlight. It can also be recharged in emergencies by mains power. By using this integrated equipment, the on-site operation time of the traditional repair process can be shortened by about 70%, and the utilization rate of repair agents can be increased by about 60%.
