Description

Technical Field

[0001] This utility model relates to the field of road cleaning equipment technology, and in particular to a portable road surface liquid suction device. Background Technology

[0002] Oil spills are inevitable during the loading, unloading, and transportation of cargo at ports. Coupled with frequent rainwater accumulation, the roads are often slippery and dirty, which not only affects the cleanliness of the port but also poses a serious threat to port facilities and cargo safety. Traditional road cleaning methods, such as manual sweeping or the use of simple cleaning equipment, are often inefficient and fail to completely remove the oil-water mixture.

[0003] To address this issue, some road surface liquid suction devices have gradually emerged on the market. These devices use a pump to generate negative pressure to suck up liquid from the road surface and use a simple filter to intercept debris. However, in practical applications, the filter is easily clogged by debris, leading to frequent equipment downtime for maintenance. This requires manual cleaning of the filter by staff, which is time-consuming and labor-intensive. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a portable road surface liquid suction device.

[0005] Technical Solution: A portable road surface liquid suction device includes a trolley. A pump is mounted on the front side of the trolley's base plate. An oil tank and a water tank are fixedly connected to the rear side of the trolley's base plate. An oil-water separator is mounted on the upper front side of both the oil tank and the water tank. The inlet of the oil-water separator is connected to the outlet of the pump via a delivery pipe. The oil outlet and water outlet of the oil-water separator are respectively connected to the interior of the oil tank and the water tank via delivery pipes. A lifting rod is detachably connected to one side of the trolley's push handle. A suction hood is fixedly connected to the lower end of the lifting rod. An annular suction chamber is opened in the lower part of the suction hood. The top of the suction chamber is connected to the inlet of the pump via a delivery pipe. Multiple suction ports that communicate with the interior of the suction chamber are circumferentially spaced on both the inner and outer sides of the lower part of the suction hood. Each suction port is connected to a filter screen. A cleaning component for cleaning all the filter screens is provided in the lower part of the suction hood.

[0006] Furthermore, the cleaning component includes multiple scraper blades 1 and 2, which are slidably connected to the suction hood. Each scraper blade 1 corresponds to a suction port on the lower outer side of the suction hood, and each scraper blade 2 corresponds to a suction port on the lower inner side of the suction hood. Both scraper blades 1 and 2 are connected to a connecting ring, and multiple abutment plates are circumferentially fixed to the bottom of the connecting ring.

[0007] Furthermore, the distance between the bottom of the contact plate and the bottom of the connecting ring is greater than the distance between the bottom of scraper one and scraper two and the bottom of the connecting ring, and when the bottom of the contact plate is flush with the bottom of the suction hood, the bottom of scraper one and scraper two is at least higher than the inner top surface of the suction port.

[0008] Furthermore, a spherical airbag is provided in the middle of the suction hood, and the airbag can move vertically inside the suction hood.

[0009] Furthermore, an electric push rod is installed on the top of the suction mask, and a lifting rod is slidably connected to the lower end of the lifting rod. The bottom end of the lifting rod slides through the top of the suction mask and is connected to the airbag. The top end of the lifting rod is connected to the telescopic rod of the electric push rod through a connecting rod, and the connecting rod is slidably connected to the lifting rod.

[0010] Furthermore, an anti-slip sleeve is attached to the upper end of the lifting rod.

[0011] Beneficial effects: By incorporating a cleaning component, this utility model allows for quick scraping and cleaning of the filter screen with a simple lifting operation of the lifting rod, preventing the filter screen from being clogged by debris, reducing the frequency of equipment downtime for maintenance, and saving manpower and time. By incorporating an airbag, the water inside the suction hood can be squeezed to the inner edge when the suction hood contacts the ground, improving the suction effect. Attached Figure Description

Detailed Implementation

[0017] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0018] Please see Figures 1-4 A portable road surface liquid suction device includes a trolley 1. A pump 8 is mounted on the front side of the base plate of the trolley 1 to generate negative pressure and suck up road surface liquid. An oil tank 9 and a water tank 10 are fixedly connected to the rear side of the base plate of the trolley 1 to store separated oil and water, respectively. An oil-water separator 11 is mounted on the upper front side of both the oil tank 9 and the water tank 10. The inlet of the oil-water separator 11 is connected to the outlet of the pump 8 through a delivery pipe. The oil outlet and water outlet of the oil-water separator 11 are respectively connected to the interior of the oil tank 9 and the water tank 10 through delivery pipes. A lifting rod 2 is detachably connected to one side of the push handle of the trolley 1. The upper end of the lifting rod 2 is connected to a non-slip sleeve 201 for easy gripping and operation. The lower end of the lifting rod 2 is fixed to a suction cover 3. The lower part of the suction cover 3 has an annular suction chamber 301. The top of the suction chamber 301 is connected to the inlet of the pump 8 through an infusion tube. The lower part of the suction cover 3 has multiple suction ports 302 that are circumferentially spaced on both the inner and outer sides and are connected to the inside of the suction chamber 301. Each suction port 302 is connected to a filter screen 4. The lower part of the suction cover 3 is provided with a cleaning component 5 for cleaning all the filter screens 4.

[0019] The cleaning component 5 in this embodiment includes multiple scraper blades 501 and 502. Both scraper blades 501 and 502 are slidably connected to the suction cover 3. Each scraper blade 501 corresponds to a suction port 302 on the lower outer side of the suction cover 3, and each scraper blade 502 corresponds to a suction port 302 on the lower inner side of the suction cover 3. All scraper blades 501 and 502 are connected to a connecting ring 503. Multiple abutment plates 504 are circumferentially fixed to the bottom of the connecting ring 503. The bottom ends of the scraper blades 501 and 502 are connected to the bottom of the connecting ring 503. The distances between the parts are equal. The distance between the bottom end of the contact plate 504 and the bottom of the connecting ring 503 is greater than the distance between the bottom ends of scraper 1 501 and scraper 2 502 and the bottom of the connecting ring 503. When the bottom end of the contact plate 504 is flush with the bottom end of the suction hood 3, the bottom ends of scraper 1 501 and scraper 2 502 are at least higher than the inner top surface of the suction port 302. This design ensures that when the suction hood 3 is in contact with the ground, the contact plate 504 contacts the ground first and drives the connecting ring 503 and scraper 1 501 and scraper 2 502 to rise, thereby exposing the suction port 302. When it is necessary to clean the filter screen 4, simply lift the lifting rod 2 upwards, and the contact plate 504, scraper 1 501 and scraper 2 502 will slide down naturally under the action of gravity, scraping the surface of the filter screen 4 to achieve quick cleaning.

[0020] To improve the suction effect, this embodiment provides a spherical airbag 6 in the middle of the suction hood 3. The airbag 6 can move vertically inside the suction hood 3. When the suction hood 3 comes into contact with the ground, the airbag 6 deforms and squeezes the water inside the suction hood 3 to the inner edge, thereby increasing the suction effect of the suction port 302.

[0021] In order to achieve the lifting and lowering control of the airbag 6, an electric push rod 701 is installed on the top of the suction cover 3 in this embodiment. The lower end of the lifting rod 2 is slidably connected to the lifting rod 702. The bottom end of the lifting rod 702 slides through the top of the suction cover 3 and is connected to the airbag 6. The top end of the lifting rod 702 is connected to the telescopic rod of the electric push rod 701 through the connecting rod 703. The connecting rod 703 is slidably connected to the lifting rod 2.

[0022] Working principle: Initially, the telescopic rod of the electric push rod 701 is in the extended state, causing the lifting rod 702 and the airbag 6 to be in a high position. During use, the trolley 1 is moved to the ground to be cleaned, and the bottom of the suction hood 3 is moved to contact the ground via the lifting rod 2. During this process, the bottom of the contact plate 504 first contacts the ground and then reverses to the connecting ring 503, causing scrapers 501 and 502 to move upwards until the bottom of the contact plate 504 is flush with the bottom of the suction hood 3. At this point, the bottom of scrapers 501 and 502 is higher than the inner top surface of the suction port 302, thus exposing all the suction ports 302 of the suction hood 3. The telescopic rod of the electric push rod 701 retracts, causing the lifting rod 702 to lower the airbag 6 to contact the ground. The 6th part deforms and squeezes the water in the suction hood 3 to the inner edge. Then, the pump 8 works, creating negative pressure in the suction chamber 301. The water on the ground is filtered through the filter screen 4 of the suction port 302 and enters the suction chamber 301. It then enters the pump 8 through the infusion pipe and enters the oil separator through the infusion pipe for oil-water separation. The separated oil and water are discharged into the oil tank 9 and water tank 10, respectively. After the extraction is completed, the lifting rod 2 is lifted upwards, causing the contact plate 504, scraper 1 501 and scraper 2 502 to slide down naturally under the action of gravity. Scraper 1 501 and scraper 2 502 can scrape and clean the filter screen 4 of their respective suction ports 302. The extension rod of the electric push rod 701 causes the lifting rod 702 and the airbag 6 to return to their original positions.

[0023] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
