With the increasing number of underwater cleaning scenarios, the use of underwater cleaning robots is becoming more common. However, there are still certain drawbacks in the cleaning and removal of silt in narrow places such as gate slots. Especially in places where the gate slots are narrow and there is a lot of moss and silt, the cleaning effect is limited.

[0003] For areas where cleaning is difficult, it is usually necessary to use a suction underwater robot and a cleaning underwater robot in combination, which is complex in operation and time-consuming and laborious. Even if the existing cleaning robots are equipped with both suction and cleaning equipment at the same time, the suction device and the cleaning equipment occupy separate positions, resulting in a large volume of the multi-functional cleaning robot, making it inconvenient to enter narrow places for operation and restricting its scope of use.

[0028] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant accompanying drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0029] As Figures 1 to 3 shown, an integrated underwater jetting and suction device includes a drainage device and a water pumping power device 2. The drainage device includes a main housing 1. The main housing 1 is a tee structure and includes a first left port 11, a first right port 12, and a bottom water inlet 13. The bottom water inlet 13 is connected to the water outlet of the water pumping power device 2. A flushing suction pipe 3 and a drain pipe 4 are respectively connected to the first left port 11 and the first right port 12. The diameter of the connection part between the first right port 12 and the drain pipe 4 is smaller than the inner diameters of the pipelines on both sides of the connection part, and a switching valve 5 is installed at the constricted narrow part. The switching valve 5 can specifically be an electromagnetic switching valve 5 to facilitate remote operation and control. The water pumping power device 2 is a propeller structure, and upward flowing water is generated by the rotation of the propeller blades to provide power for water intake.

[0030] The first right port 12 of the drainage device is a tapered closing structure that gradually narrows in the direction away from the first left port 11; the drainage pipe 4 as a whole is an expanding structure in which the inner diameter of the pipe gradually expands in the direction away from the drainage device, and the taper of the expanding structure is smaller than that of the tapered closing structure, and the taper of the expanding structure is 3°-15°. With this structural design, when the water flows through the tightened narrow part of the pipe, its flow rate will increase significantly, thereby forming a pressure difference at the tightened narrow part. Under the action of this pressure difference, the water inside the main shell 1 will flow to the right, thereby forming a siphon effect; then the opening and closing of the tightened narrow part is controlled by switching the valve 5, thereby controlling the direction of the water flow, and finally realizing the switching of the underwater spraying and suction functions. The overall device is cleverly designed and easy to operate, making the entire underwater obstacle removal work fast and effective, significantly improving its underwater work efficiency, meeting actual needs, and having a wide range of uses.

[0031] A second transverse tube 6 is arranged inside the main shell 1 located on the side of the first left port 11, and the extension length of the second transverse tube 6 exceeds the width of the bottom water inlet 13; the right end of the second transverse tube 6 extends into the conical closing structure of the first right port 12, and is spaced from the inner wall of the conical closing structure, so that a flow space is left between the inner wall of the main shell 1 and the second transverse tube 6, which is convenient for water to flow, enter and switch from the bottom water inlet 13 to the inside of the main shell 1, and finally effectively control the switching of the cleaning spray and suction functions.

[0032] The outer diameter of the second transverse tube 6 is smaller than the inner diameter of the main shell 1. A flange baffle 7 is fixed to the left end of the second transverse tube 6, and the left end of the second transverse tube 6 is installed at the first left port 11 of the main shell 1 through the flange baffle 7, and is sealed and connected to the first left port 11 of the main shell 1; the flushing and suction pipe 3 is a horizontal straight pipe, one end of which extends into the second transverse tube 6, and the outer wall of the flushing pipe is sealed with the inner wall of the second transverse tube 6.

[0033] The diameter of the first right port 12 of the drainage device is larger than the diameter of the first left port 11 of the drainage device. With this structural design, when the second transverse pipe 6 is fixed to the first left port 11 of the main shell 1 through the flange baffle 7, a flow space will be formed between the inside of the main shell 1 and the outer wall of the second transverse pipe 6. The pumping power device 2 delivers water to the inside of the main shell 1 from the bottom water inlet 13. The inlet water will enter the cavity between the inside of the main shell 1 and the outer wall of the second transverse pipe 6 from the bottom water inlet 13, and reach the right side of the second transverse pipe 6, that is, the switching valve 5 between the second transverse pipe 6 and the tightening narrow mouth. By controlling the switching valve 5, the water flow is finally controlled to flow out from the drainage pipe 4 or the flushing and suction pipe 3 in two opposite directions, and finally the switching of the suction and cleaning functions is realized.

[0034] A clamping convex ring 8 is also provided on the outer wall of the flushing and suction pipe 3 which does not extend into the second transverse pipe 6, so that its front end can be easily connected to other mechanical claws for coordinated action, thereby improving its application range and dredging effect.

[0035] The center lines of the flushing suction pipe 3, the second horizontal pipe 6, the tightened narrow part, and the drain pipe 4 are on the same straight line. When designed according to this structure, the volume of the integrated underwater jetting and suction device of the present utility model is the smallest, and it can provide the maximum power for underwater jetting and suction, saving time and effort and significantly improving work efficiency.

[0036] An outlet pipe mounting ring 9 is provided at the outer end of the drain pipe 4, which is convenient for connecting other pipelines and equipment and expanding its scope of use.

[0037] The integrated underwater jetting and suction device of the present utility model is mainly used for underwater obstacle removal related operation tasks. By controlling the opening and closing of the switching valve 5 on the drain pipe 4, the switching between the underwater jetting cleaning mode and the suction dredging mode can be carried out, and the random switching selection between the underwater jetting cleaning function and the suction dredging function can be realized. When the switching valve 5 is open, it is the suction dredging mode; when the switching valve 5 is closed, it is the underwater jetting cleaning mode.

[0038] The specific usage principle is as follows:

[0039] When the integrated underwater jetting and suction device is in the underwater jetting cleaning state, the switching valve 5 is in the closed state, and the water flow generated by the water pumping power device 2 returns through the flushing suction port of the flushing suction pipe 3 and sprays out when passing through the drainage device, achieving the flushing effect on sundries such as silt.

[0040] When the integrated underwater jetting and suction device is in the underwater suction state, the switching valve 5 is in the open state, and a pressure difference is generated when the water flow generated by the water pumping power device 2 passes through the drainage device, causing the water on the flushing suction port side to flow towards the drainage port of the drain pipe 4 under the action of pressure through the flushing suction pipe 3, realizing the suction function. At the same time, the silt at the flushing suction port is sucked into the drainage device from the flushing suction pipe 3 and finally discharged from the drain pipe 4 together with the water flow, achieving the suction dredging effect.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
