Description

Technical Field

[0001] The utility model relates to the technical field of robots, and more specifically, to an underwater robot. Background Art

[0002] Existing pool robots usually have only one filtering device. Although this design meets the basic cleaning requirements to a certain extent, it is difficult to cope with the challenges of complex water quality environments. Specifically, when the aperture of the filtering device is set too large, although it can ensure the smooth flow of water and is not easily blocked, it is difficult to effectively capture and collect small granular garbage or cotton-like suspended substances underwater. If these tiny pollutants remain in the pool for a long time, they will not only affect the water quality but also pose a potential threat to the health of swimmers. On the contrary, if the aperture is set too small to improve the filtering effect, the garbage bin is extremely likely to be blocked, greatly affecting the cleaning efficiency, and may even cause abnormal operation of the robot due to the blocked water flow, or even damage the internal structure of the machine, increasing the maintenance cost.

[0003] In addition, the design of a single filtering device also limits the adaptability of pool robots under different water quality conditions. Due to differences in usage frequency, maintenance status, and water quality treatment methods, the water quality conditions of different pools vary greatly. A filtering device with a single aperture is difficult to maintain the best cleaning effect under various water quality conditions, which to a certain extent limits the application range and usage effect of pool robots. Summary of the Utility Model

[0004] The utility model aims to overcome at least one of the above-mentioned deficiencies of the prior art, and provides an underwater robot for solving the problem that the existing filtering design is prone to blockage when collecting small particles or flocs.

[0005] The technical solution adopted by the utility model is to provide an underwater robot, including a housing and a dirt collection bin arranged inside the housing. The housing is provided with a water outlet and a water inlet connected to the dirt collection bin. The bottom surface and side surface of the dirt collection bin form a first filtering structure, and a second filtering structure is arranged between the dirt collection bin and the water outlet. Through the carefully designed secondary filtering system, the hierarchical collection and treatment of underwater impurities are realized, the processing ability of the underwater robot for different types of small objects and flocs is enhanced, the blockage problem that may be caused by a single filtering mechanism is avoided, and the ability of the underwater robot to operate stably for a long time is ensured.

[0006] Furthermore, the water inlet is arranged at the bottom of the housing, and a water inlet channel is arranged between the water inlet and the dirt collecting bin, one end of the water inlet channel is connected to the water inlet, and the other end is connected to the dirt collecting bin through a first filtering structure. The drainage of the water inlet channel and the first filtering structure can help control the movement of the water flow in the dirt collecting chamber and guide the movement trajectory of the water flow, thereby reducing the impact and prolonging the separation time of the water flow and the debris.

[0007] Furthermore, a drainage chamber is provided in the shell, and the drainage chamber is arranged on a side of the dirt collecting bin away from the water inlet channel; one side of the drainage chamber is connected to the dirt collecting bin through a second filtering structure, and the other side is connected to the water outlet. The drainage chamber can buffer the filtered liquid, and its position is away from the water inlet channel, which helps to extend the transmission path of the water flow and increase the separation time of the debris, thereby improving the separation effect.

[0008] Furthermore, the first filter structure forms a first filter surface between the water inlet channel and the dirt collection bin; the second filter structure forms a second filter surface between the drainage chamber and the second filter structure. The design of double filter surfaces is suitable for application scenarios where finer particles or flocs need to be filtered.

[0009] Furthermore, the first filter surface and / or the second filter surface are arranged at an angle to the bottom of the housing; the first filter surface and the second filter surface have different orientations. The inclined filter surface increases the contact area of ​​filtration in a limited space and improves the filtration efficiency. At the same time, the design of different orientations avoids direct impact of the water flow, prolongs the passage path of the water flow, and provides favorable conditions for the full separation of debris.

[0010] Furthermore, the first filter surface and the second filter surface are inclined relative to the bottom of the shell; the angle between the first filter surface and the bottom of the shell is greater than the angle between the second filter surface and the bottom of the shell; the bottom ends of the first filter surface and the second filter surface are close to each other and the top ends are far away from each other. This special tilt angle design further improves the filtration efficiency. The large angle design of the first filter surface helps the water flow to impact the top of the sewage collection bin, forming a return of the water flow and extending the movement path of the water flow; while the small angle of the second filter surface makes it easier to receive the falling water flow from the front and guide the filtration to gradually act from top to bottom, achieving more complete contact between the water flow and the second filter surface and promoting efficient separation of debris.

[0011] Furthermore, a support frame is also provided inside the sewage collection bin; a partition is formed between the sewage collection bin and the drainage chamber through a liquid guide partition plate with holes, and an insertion installation cavity is formed between the liquid guide partition plate and the support frame; the second filtering structure is detachably arranged in the insertion installation cavity. The setting of the support frame not only enhances the structural stability of the sewage collection bin, but also provides a convenient installation and fixing method for the second filtering structure, making the maintenance and replacement work simpler and more efficient.

[0012] Furthermore, the second filtering structure is a flat filtering barrier, and the filtering pore diameter of the second filtering structure is smaller than that of the first filtering structure. The flat barrier helps to improve the filtering speed, and the limitation of the pore diameter difference helps to effectively filter different sundries and avoid blockage.

[0013] Furthermore, the second filtering structure includes a frame and a core body arranged inside the frame, and the core body is a corrugated structure. The corrugated core body design greatly increases the surface area of the core body and enhances the filtering effect. In some embodiments, the core body is composed of one or more of filter paper, filter cotton, non-woven fabric, and microporous filter membrane stacked on each other.

[0014] Furthermore, a filter material accommodation cavity is arranged inside the core body, and filter materials are filled in the filter material accommodation cavity. The filter materials include one or a combination of more than one of filter cotton, activated carbon, ceramsite, fiber ball filter material, porous gel, volcanic rock filter material, and fiber bundle. Multiple filter material accommodation cavities can be provided to facilitate filling different fillers and replacing them separately according to the degree of sundry adsorption. The filling of the filter materials further improves the filtering effect, enhances the filtering ability of the robot for different types of sundries, and makes it more reliable and efficient in underwater operations.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The underwater robot provided by the present utility model significantly enhances the compatibility and filtering efficiency for various fine and flocculent sundries through a hierarchical filtering design, avoiding the blockage problem; the combination of its water inlet channel and the inclined filtering surface optimizes the water flow path and prolongs the sundry separation time; the second filtering structure is detachable, facilitating daily maintenance; the combination of the flat and corrugated filter elements increases the filtering area, ensuring efficient and stable underwater operation ability.

[0024] Embodiment 1

[0025] As Figures 1 to 5 shown, this embodiment provides an underwater robot, including a housing 100 and a dirt collection bin 400 arranged inside the housing 100. A water outlet 120 and a water inlet 110 connected to the dirt collection bin 400 are arranged on the housing 100. The bottom surface and side surface of the dirt collection bin 400 form a first filtering structure 300, and a second filtering structure 500 is arranged between the dirt collection bin 400 and the water outlet 120. Through the carefully designed secondary filtering system, the hierarchical collection and treatment of underwater impurities are realized, the processing ability of the underwater robot for different types of fine objects and flocs is enhanced, the blockage problem that may be caused by a single filtering mechanism is avoided, and the ability of the underwater robot to operate stably for a long time is ensured.

[0026] The water inlet 110 is arranged at the bottom of the housing 100. An water inlet channel 200 is arranged between the water inlet 110 and the dirt collection bin 400. One end of the water inlet channel 200 is connected to the water inlet 110, and the other end is communicated with the dirt collection bin 400 through the first filtering structure 300. With the drainage of the water inlet channel 200 and the cooperation of the first filtering structure 300, it can help control the movement of the water flow in the dirt collection cavity, guide the movement track of the water flow, so as to reduce the impact while prolonging the separation time of the water flow and the sundries.

[0027] The housing 100 is further provided with a drainage chamber 600, which is arranged on a side of the dirt collecting bin 400 away from the water inlet channel 200; one side of the drainage chamber 600 is connected to the dirt collecting bin 400 via the second filtering structure 500, and the other side is connected to the water outlet 120. The drainage chamber 600 can buffer the filtered liquid, and its location away from the water inlet channel 200 helps to extend the transmission path of the water flow, increase the separation time of the debris, and thus improve the separation effect.

[0028] The first filter structure 300 forms a first filter surface between the water inlet channel 200 and the dirt collecting bin 400, and the second filter structure 500 forms a second filter surface between the drainage chamber 600 and the second filter structure 500. The design of double filter surfaces is suitable for application scenarios where finer particles or flocs need to be filtered.

[0029] The second filtering structure 500 may also be disposed between the drainage chamber 600 and the water outlet 120 , or disposed at the water outlet 120 , both of which can achieve the same effect.

[0030] When the second filter structure 500 is set, it can be set to a rectangular, square or circular structure according to its fixed position, or it can be set to a structure substantially the same as the water outlet 120 .

[0031] The first filter surface and the second filter surface are arranged obliquely with respect to the bottom of the housing 100; the first filter surface and the second filter surface have different orientations. The inclined filter surface increases the contact area of ​​filtration in a limited space and improves the filtration efficiency. At the same time, the design of different orientations avoids direct impact of water flow, prolongs the passage path of water flow, and provides favorable conditions for the full separation of debris.

[0032] The first filter surface and the second filter surface are inclined relative to the bottom of the shell 100; the angle between the first filter surface and the bottom of the shell 100 is greater than the angle between the second filter surface and the bottom of the shell 100; the bottom ends of the first filter surface and the second filter surface are close to each other and the top ends are far away from each other. This special tilt angle design further improves the filtration efficiency. The large angle design of the first filter surface helps the water flow to impact the top of the sewage collection bin 400, forming a return of the water flow and extending the movement path of the water flow; while the small angle of the second filter surface makes it easier to receive the falling water flow from the front and guide the filtration to gradually act from top to bottom, achieving more complete contact between the water flow and the second filter surface and promoting efficient separation of debris.

[0033] A support frame 410 is also provided inside the sewage collection bin 400; a partition is formed between the sewage collection bin 400 and the drainage chamber 600 through a liquid guide partition plate 420 with holes, and an insertion installation cavity is formed between the liquid guide partition plate 420 and the support frame 410; the second filtering structure 500 is detachably arranged in the insertion installation cavity. The setting of the support frame 410 not only enhances the structural stability of the sewage collection bin 400, but also provides a convenient installation and fixing method for the second filtering structure 500, making the maintenance and replacement work simpler and more efficient.

[0034] The second filtering structure 500 is a flat filtering barrier, and the filtering pore diameter of the second filtering structure 500 is smaller than that of the first filtering structure 300. The flat barrier helps to improve the filtering speed, and the limitation of the pore diameter difference helps to effectively filter different sundries and avoid blockage.

[0035] The second filtering structure 500 includes a frame and a core body arranged inside the frame, and the core body is a corrugated structure. The corrugated core body design greatly increases the surface area of the core body and enhances the filtering effect. The core body is composed of one or more of filter paper, filter cotton, non-woven fabric, and microporous filter membrane stacked on each other.

[0036] A filter material accommodation cavity is arranged inside the core body, and filter materials are filled in the filter material accommodation cavity. The filter materials include one or a combination of more than one of filter cotton, activated carbon, ceramsite, fiber ball filter material, porous gel, volcanic rock filter material, and fiber bundle. Multiple filter material accommodation cavities can be arranged to facilitate filling different fillers and replacing them separately according to the degree of sundry adsorption. The filling of the filter materials further improves the filtering effect, enhances the filtering ability of the robot for different types of sundries, and makes it more reliable and efficient in underwater operations.

[0037] The underwater robot provided in this embodiment significantly enhances the compatibility and filtering efficiency for a variety of fine and flocculent sundries through a hierarchical filtering design, avoiding the blockage problem; the combination of its water inlet channel 200 and the inclined filtering surface optimizes the water flow path and extends the sundry separation time; the second filtering structure 500 is detachable, facilitating daily maintenance; the combination of the flat and corrugated filter elements increases the filtering area, ensuring an efficient and stable underwater operation ability.
