Description

Technical Field

[0001] The present application relates to the technical field of underwater sewage pumping and cleaning equipment, and in particular to a solid matter rolling and scraping machine before underwater sewage pumping. Background Art

[0002] Water pollution is a major problem facing people today. Existing water pollution control is mostly to clean up pollutants on the water surface or the bottom of the water. When cleaning up pollutants on the bottom of the water, because water pollutants are deposited on the bottom of the water in order, that is, the earlier sediments are at the bottom of the bottom of the water sludge. The bottom sludge is generally fully decomposed or closed by the sludge, isolating oxygen for a long time, so that the organic matter is solidified. The sediments deposited on the surface of the bottom sludge later contain a large amount of organic degradable pollutants such as animal and plant debris, which can easily cause water pollution.

[0003] In existing underwater dredging operations, sewage is directly pumped out from the bottom of the water using a sewage pump, which usually only pumps out the silt and a large amount of water on the surface of the bottom of the water. After the pollutants in the semi-sedimentation layer are exposed, the pollutants that have not been fully decomposed will come into contact with oxygen again, re-produce decomposition products that are harmful to the water quality, and release them into the water body, polluting the water body, resulting in poor water pollution control effects.

Beneficial Effects

[0015] 1. The present application provides a machine for crushing and leveling solid pollutants before underwater sewage pumping. When a crawler-type moving body moves on the bottom of the water, a solid crushing device is used to squeeze the solid pollutants on the surface of the bottom of the water downward, so that the solid pollutants on the surface of the bottom of the water are squeezed to a certain depth under the silt until the solid pollutants are covered by the silt, thereby turning up the silt on the bottom that has little or no effect on the water quality, muddying the overall water quality, and making the muddy water slurry wrap around the lighter suspended matter in the water body, prompting the suspended matter to settle faster, facilitating the subsequent sewage pumping of the bottom sediment, and achieving better bottom cleaning effect. The silt covering and sealing is also used to isolate oxygen, so that pollutants do not harm the water quality, and rotten decomposition products are not released into the water body, ensuring that the bottom of the water will not be polluted again for a long time after cleaning, so that the water pollution control effect is better, and the scraping member and baffle set at the rear end of the crawler-type moving body are used to scrape the silt, which further facilitates the subsequent sewage pumping and cleaning operations on the bottom of the water.

[0016] 2. A solid crushing device is formed by setting a number of equidistantly arranged annular pressure plates on the middle pressure roller, and gaps are left between the annular pressure plates, so that the gravity of the middle pressure roller and the annular pressure plates can be utilized. When the crawler-type moving body moves on the bottom of the water, the solid pollutants on the bottom surface of the water are squeezed to a certain depth under the silt through the annular pressure plates, so that the solid pollutants are covered by the silt, and in the process of crushing the solid objects by the annular pressure plates, the sewage slurry contained in the decomposition of the pollutants is squeezed out, which is convenient for the subsequent extraction of the sewage slurry in the bottom silt, further improving the bottom cleaning effect.

A plurality of annular pressure plates are respectively arranged on a plurality of intermediate pressure wheels, and the intermediate pressure wheels are fitted together, and a chain is used to pass through the middle of all the intermediate pressure wheels, and a second tension spring is connected to both ends of the chain. When working underwater, when the underwater ground is uneven, each of the pressure wheels can be displaced and moved relative to each other, so that the annular pressure plates on each intermediate pressure wheel can contact the underwater ground, so as to squeeze the solid pollutants downward, so that the silt completely covers the solid pollutants, and avoids the problem that the solid pollutants in the groove cannot be pressed down due to the uneven underwater ground, resulting in the silt covering the solid pollutants.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Embodiment 1

[0037] See also Figure 1-Figure 2A solids crushing and scraping machine before underwater sewage pumping includes a crawler-type moving body 1, and the four corners of the top of the crawler-type moving body 1 are fixedly connected with telescopic connection mechanisms. The top of the telescopic connection mechanism is fixedly connected with a hull 3, so that the crawler-type moving body 1 can stably move on the bottom of the water, ensuring the connection and control of the hull and the crawler-type moving body 1 when the water level changes. The telescopic connection mechanism includes a lower square tube 201 and an upper square tube 202. The upper square tube 202 is movably mounted inside the lower square tube 201, and the top of the lower square tube 201 is fixedly connected and wrapped outside the lower square tube 201. The conical limiting tube on the side ensures that the upper square tube 202 can stably move longitudinally along the lower square tube 201, and the bottom end of the lower square tube 201 is fixedly connected to the top of the crawler-type moving body 1, and the top of the upper square tube 202 is fixedly connected with a sealing plate 203, and the sealing plate 203 is sealed with the hull 3 to prevent water from seeping into the hull 3. Plug holes are provided on the lower square tube 201 and the upper square tube 202, and the plug rod is inserted into the plug hole. After controlling the total length of the telescopic connection mechanism, the plug rod can be used for limiting, ensuring that the hull 3 is on the water surface and the crawler at the bottom of the crawler-type moving body 1 can walk on the bottom of the water.

[0038] A foldable hydraulic pipeline fixing frame is provided between the hull 3 and the crawler traveling body 1, and the foldable hydraulic pipeline fixing frame includes a pipeline frame 4, and the number of the pipeline frames 4 is not less than two, and an L-shaped connector 5 is connected between every two pipeline frames 4 through a rotating shaft.

The silt cover is also used to seal and isolate oxygen, so that the pollutants do not harm the water quality, and the rotten decomposition products will not be released into the water body, ensuring that the bottom of the water will not be polluted again for a long time after cleaning. In the process of crushing the solid objects on the annular pressure plates 10, the sewage slurry contained in the decomposition of the pollutants is squeezed out, which is convenient for the subsequent pumping away of the sewage slurry in the silt on the bottom of the water, further improving the cleaning effect of the bottom of the water.

[0040] The front end of the crawler traveling body 1 is rotatably connected to the first hydraulic cylinder 11, and the output shaft of the first hydraulic cylinder 11 is rotatably connected to the top of the limiting plate 8.

At the same time, the gathering plates 14 at both ends of the scraper 13 ensure that when the scraper 13 scrapes the sludge, the sludge will not emerge from the two ends of the scraper 13, thereby ensuring the scraping effect of the underwater sludge.

[0042] The depth indicating mechanism includes two marking columns 301 fixedly installed on the top of the hull 3, and the tops of the two marking columns 301 are respectively provided with pulleys. The top sides of the crawler-type traveling body 1 are respectively fixedly connected with transverse support rods 101, and one end of the two transverse support rods 101 is respectively provided with pulleys.

[0044] Under normal conditions, the chain 16 is in a flattened state by the pulling force of the second tension spring 21, so that each 9 between the two guide chain wheels 18 remains in a flat state. During underwater operations, when the underwater ground is uneven, compared with the first embodiment, each 9 can be displaced and moved relative to each other, so that the annular pressure plates 10 on each 9 can contact the underwater ground, so as to squeeze the solid pollutants downward, so that the silt completely covers the solid pollutants, thereby avoiding the problem that the solid pollutants in the groove cannot be pressed down due to the uneven underwater ground, resulting in the silt covering the solid pollutants.
