DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0019] Example 1

[0020] like Figures 1 to 11As shown, a sewage lifting pump that is easy to clean includes an outer shell 100, a rotating shaft 101 is installed inside the outer shell 100, a blade 102 is installed at one end of the rotating shaft 101, a cleaning unit is arranged inside the outer shell 100, the cleaning unit includes a folding mechanism and a scraper 204, the folding mechanism includes a first folding rod 202 and a second folding rod 203, and the first folding rod 202 is rotatably connected to the second folding rod 203, the second folding rod 203 is rotatably connected to the scraper 204, and the folding mechanism is used to fold and retract the scraper 204; A driving unit is also provided inside the outer shell 100. The driving unit includes a matching mechanism, which includes a connecting column 302 and a connecting head 304. An adapting groove 305 is provided at one end of the connecting column 302, and an adapting head 306 is fixedly installed at one end of the connecting head 304. The driving unit drives the cleaning unit to work through the mutual matching of the adapting groove 305 and the adapting head 306. The side walls of the adapter head 306 and the adapter slot 305 are both provided with spiral patterns having the same rotation direction as the rotation direction of the rotating shaft 101. When the rotation speed of the adapter head 306 is greater than that of the adapter slot 305, the spiral patterns on the adapter head 306 are inserted into the spiral patterns on the adapter slot 305. When the rotation speed of the adapter head 306 is less than that of the adapter slot 305, the spiral patterns on the adapter head 306 are gradually separated from the spiral patterns on the adapter slot 305.

[0021] like Figures 2 to 6 As shown, in a specific embodiment, the cleaning unit also includes a mounting shell 200, which is movably sleeved on the rotating shaft 101, and mounting frames 201 are installed on both sides of the mounting shell 200. The first folding rod 202 is rotatably connected to the mounting frame 201, and a supporting mechanism is arranged between the first folding rod 202 and the second folding rod 203. The supporting mechanism is used to maintain the horizontal state of the second folding rod 203 when the first folding rod 202 is in a horizontal state. The supporting mechanism includes a side block 205 and a push block 208, and the side block 205 is fixedly connected to the second folding rod 203. A slider 207 is fixedly installed at one end of the push block 208, and a slide bar 206 is fixedly installed at the bottom of the first folding rod 202. The slider 207 is movably sleeved on the slide bar 206, and the supporting mechanism supports the second folding rod 203 through the side block 205 and the push block 208. In this configuration, when the first folding rod 202 and the second folding rod 203 are unfolded, the connecting plate 211 moves with them and pushes the slider 207 to move under the action of the rotating plate 210, thereby moving the push block 208 to the bottom of the side block 205. At this time, the second folding rod 203 remains in a horizontal state under the support of the push block 208 and the side block 205, preventing it from rotating downward and colliding with the blade 102.

[0022] like Figures 3 to 5As shown, further, the cleaning unit also includes a limiting mechanism, which includes a fixed plate 209, the fixed plate 209 is fixedly connected to the mounting frame 201, one end of the fixed plate 209 is rotatably connected to a rotating plate 210, one end of the rotating plate 210 is rotatably mounted with a connecting plate 211, both ends of the connecting plate 211 are rotatably connected to the slider 207, and the connecting plate 211 drives the slider 207 to move when following the movement of the rotating plate 210. In this setting, the moving trajectory of the connecting plate 211 is the rotation route of the rotating plate 210, and when the first folding rod 202 rotates, the slider 207 on the first folding rod 202 rotates accordingly, and at this time, the slider 207 is pulled by the connecting plate 211 and slides along the slide bar 206.

[0023] In this embodiment, the first folding rod 202 and the second folding rod 203 are provided with two groups distributed up and down, and are respectively connected to the upper and lower ends of the scraper 204. The rotating plate 210 is provided with two groups distributed up and down, and forms a quadrilateral structure with the connecting plate 211.

[0024] Example 2

[0025] like Fig. 9 , Fig.10 As shown, in a specific embodiment, the driving unit further includes a buffer mechanism, which includes a driving torsion spring 301, which is movably sleeved on the rotating shaft 101, and a connecting disk 300 is installed at one end of the driving torsion spring 301, and one end of the connecting disk 300 is fixedly connected to the mounting shell 200, and the other end of the driving torsion spring 301 is fixedly connected to a connecting column 302, and the connecting column 302 is movably connected inside the mounting shell 200. In this setting, when the driving torsion spring 301 is subjected to the rotational force from the connecting column 302, it is torsionally deformed, and the torsion generated by the torsion deformation is then applied to the connecting disk 300, thereby realizing flexible transmission of the cleaning unit and avoiding the high-speed rotation of the connecting shaft being directly transmitted to the cleaning unit.

[0026] like Figure 6 As shown, further, the driving unit also includes a pressure mechanism, which includes a connecting rod 401, which is rotatably connected to the rotating shaft 101, a counterweight 400 is fixedly installed on the top of the connecting rod 401, and a pressure plate 402 is rotatably connected to one end of the connecting rod 401, and the bottom of the pressure plate 402 is rotatably connected to the connecting head 304, and the pressure mechanism drives the connecting head 304 to move downward through the centrifugal force generated by the rotation of the counterweight 400. In this setting, the rotating shaft 101 rotates and drives the counterweight 400 to rotate. The counterweight 400 opens outward under the centrifugal force generated by the rotation and drives the connecting rod 401 to rotate. The connecting rod 401 drives the connecting head 304 to descend through the pressure plate 402.

[0027] like Figure 6 , Figure 8-Figure 10As shown, further, the pressure mechanism also includes a reset assembly, which includes a spring 404, which is movably sleeved on the rotating shaft 101, and a first support ring 403 is fixedly installed on the top of the spring 404, and the first support ring 403 is located at the bottom of the connecting rod 401. The reset assembly also includes a second support ring 405, which is movably sleeved on the outside of the connecting head 304, and a support block 406 is fixedly installed on the top of the second support ring 405. A positioning rod 418 is installed at one end of the support block 406, and the positioning rod 418 is movably plugged into the connecting head 304. A connecting ring 303 is fixedly installed on the top of the connecting column 302, and the connecting ring 303 is movably plugged into the connecting head 304. In this setting, the spring 404 drives the first support ring 403 to move, and the first support ring 403 drives the connecting rod 401 to rotate, so that the connecting head 304 moves upward, and the connecting head 304 always maintains a connection state with the connecting ring 303 during the movement, effectively preventing dirt from entering the inside of the connecting head 304.

[0028] Example 3

[0029] like Figure 2 , Figure 6 to Figure 7 As shown, in a specific embodiment, the driving unit also includes a pulling mechanism, which includes a mounting seat 415, which is fixedly mounted on the top of the outer shell 100, and the rotating shaft 101 movably passes through the mounting seat 415. A pushing component is installed on the mounting seat 415, and the pushing component includes an electric cylinder 417. A connecting component is provided at the output end of the electric cylinder 417, and a pull rod 411 is provided at the bottom of the connecting component. The connecting component includes a lower turntable 412 and an upper turntable 413, and the lower turntable 412 and the upper turntable 413 are rotatably connected. The bottom of the lower turntable 412 is fixedly connected to the pull rod 411, and the upper turntable 413 is fixedly connected to the output end of the electric cylinder 417. A slot 414 is opened on the upper turntable 413, and an insert block 416 is fixedly installed at the bottom of the mounting seat 415, and the slot 414 is adapted to the insert block 416. The lower turntable 412 and the insert block 416 are both frosted on one side close to each other. In this configuration, when the electric cylinder 417 contracts, the electric cylinder 417 drives the upper turntable 413 and the lower turntable 412 to rise, and inserts the insert block 416 into the slot 414. At this time, the insert block 416 and the lower turntable 412 squeeze each other, and the friction force prevents the lower turntable 412 from rotating.

[0030] like Figure 6As shown, further, a connecting member 408 is fixedly installed at the bottom of the pull rod 411, a roller 407 is rotatably installed on one side of the connecting member 408, the roller 407 is located at the bottom of the second support ring 405, a pull plate 409 is rotatably installed at the bottom of the connecting member 408, a slide groove 410 is provided on the first folding rod 202, and one end of the pull plate 409 is slidably connected to the slide groove 410 through a connecting shaft. In this configuration, the roller 407 and the connecting member 408 are connected through a bearing to meet the support function of the roller 407 on the second support ring 405 when the second support ring 405 rotates.

[0031] The implementation principle of the sewage lifting pump that is easy to clean in this embodiment is as follows: when the sewage lifting pump is working normally, the electric cylinder 417 is in a retracted state, at which time the first folding rod 202 and the second folding rod 203 are in a retracted state, and the connecting head 304 and the connecting column 302 are in a separated state, so that the scraper 204 does not rotate; When cleaning is required, the sewage lifting pump is connected to the clean water source, and the electric cylinder 417 is started. The electric cylinder 417 drives the upper turntable 413 and the lower turntable 412 to descend, thereby causing the pull rod 411 to descend. At this time, the pull rod 411 drives the pull plate 409 to slide along the slide groove 410 through the connecting member 408, and at the same time, the connecting member 408 drives the roller 407 to descend. At this time, the second support ring 405 descends due to the loss of the support of the roller 407; Start the sewage lifting pump, at this time, the rotating shaft 101 rotates, and drives the counterweight block 400 to rotate. The counterweight block 400 opens outward under the centrifugal force generated by the rotation, and drives the connecting rod 401 to rotate. The connecting rod 401 drives the connecting head 304 to descend through the pressure plate 402. When the adapter groove 305 cooperates with the adapter head 306, the connecting head 304 drives the connecting column 302 to rotate. At this time, the connecting column 302 drives the driving torsion spring 301 to rotate. The torsion of the driving torsion spring 301 acts on the connecting disk 300, thereby rotating the mounting shell 200. When the mounting shell 200 rotates, it drives the first folding rod 202 and the second folding rod 203 to rotate, so that the first folding rod 202 and the second folding rod 203 are thrown away under the action of centrifugal force; When the first folding rod 202 and the second folding rod 203 are unfolded, the connecting plate 211 moves with them and pushes the slider 207 to move under the action of the rotating plate 210, thereby moving the push block 208 to the bottom of the side block 205. At this time, the second folding rod 203 is kept in a horizontal state under the support of the push block 208 and the side block 205, so as to prevent it from rotating downward and colliding with the blade 102. When the first folding rod 202 and the second folding rod 203 are unfolded, the scraper 204 is driven to unfold. At this time, the scraper 204 scrapes the inner wall of the outer shell 100, and the scraped dirt is washed away with the water flow; When the cleaning is completed, the sewage lifting pump is disconnected from the clean water source, and the sewage lifting pump is shut down at this time. The rotating shaft 101 and the blades 102 are decelerated under the damping action of the sewage lifting pump itself. At the same time, the cleaning unit continues to rotate due to its own inertia, so that the rotation speed of the connecting head 304 is slower than the rotation speed of the connecting column 302, that is, the connecting head 304 rotates in the opposite direction relative to the connecting column 302. At the same time, due to the reduction in the rotation speed of the rotating shaft 101, the rotation speed of the counterweight block 400 is reduced, and the centrifugal force is reduced. At this time, the spring 404 drives the first support ring 403 to move, and the first support ring 403 drives the connecting rod 401 to rotate, so that the connecting head 304 moves up and is separated from the connecting column 302; The electric cylinder 417 is retracted, and the electric cylinder 417 drives the upper turntable 413 and the lower turntable 412 to rise, and the insert block 416 is inserted into the slot 414. At this time, the insert block 416 and the lower turntable 412 are squeezed against each other, and the lower turntable 412 cannot rotate due to the friction force. At the same time, the lower turntable 412 drives the connecting member 408 to rise through the pull rod 411, and the connecting member 408 drives the roller 407 to rise, so that the second support ring 405 rises, and drives the support block 406 to press against the first support ring 403; As the connecting member 408 rises, the first folding rod 202 is pulled to rotate through the pulling plate 409. During the rotation of the first folding rod 202, the slider 207 moves under the action of the rotating plate 210 and the connecting plate 211, and drives the pushing block 208 to separate from the side block 205. At this time, the second folding rod 203 and the scraper 204 rotate downward under the action of gravity, thereby achieving the effect of folding and shrinking.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
