DETAILED DESCRIPTION

[0032] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0033] like Figures 1-15As shown, the present invention provides an environmentally friendly overflow outlet for port dredging, including a drain pipe 1, wherein the inner wall of the drain pipe 1 is provided with a rotatable drive cylinder 12, the outer surface of the drive cylinder 12 is provided with a drive ring 18, the drive ring 18 is provided with a plurality of arc scrapers 25, and the arc scrapers 25 are respectively provided with a plurality of serrations 26. When the drive cylinder 12 rotates, a structure in which the drive ring 18 and the arc scraper 25 rotate and move back and forth left and right can be formed. When the drive ring 18 moves to the top end to the left, a structure in which the arc scraper 25 rotates and moves outward to expand can be formed. When the drive ring 18 moves to the top end to the right, a structure in which the arc scraper 25 rotates and moves inward to close can be formed.

[0034] like Figures 1-8 As shown, the drain pipe 1 is installed in the port channel. When the water level in the port reaches the height of the drain pipe 1, the water flows into the other end of the drain pipe 1 under its own flow and is discharged, thereby controlling the water level line of the port and preventing the water in the port from overflowing; the driving cylinder 12 can provide power for the driving ring 18, the arc scraper 25, etc. When the arc scraper 25 is unfolded, the arc scraper 25 can contact the inner wall of the drain pipe 1. When the driving cylinder 12 rotates, it can drive the corresponding driving ring 18, the arc scraper 25, the serrations 26, etc. to rotate and move to one side synchronously. When the arc scraper 25 is in the open state and in contact with the inner wall of the drain pipe 1, the arc scraper 25 can scrape the inner wall of the drain pipe 1, thereby cleaning the impurities adhering to the drain pipe 1, and the serrations 26 rotate. When the driving ring 18 moves to the left, the arc scraper 25 can move outward, that is, the arc scraper 25 contacts the inner wall of the drain pipe 1, and the drain pipe 1 can be scraped when the arc scraper 25 moves. When the driving ring 18 moves to the right, the arc scraper 25 can be driven to move inward while rotating, so that the arc scraper 25 is in a retracted state, and when it rotates to the specified position, the resistance of the water flow can be reduced, that is, the energy consumption is reduced when it moves to one side.

[0035] The first support frame 9 is fixedly connected to the inner wall of the left end of the drainage pipe 1, and the driving cylinder 12 is rotatably connected to the inner wall of the support frame. The first motor 8 is fixedly connected to the left end surface of the support frame, and the driving cylinder 12 is fixedly connected to the output end of the first motor 8; the second support frame 14 is fixedly connected to the right end surface of the drainage pipe 1, and the threaded rod 13 is fixedly connected to the inner wall of the second support frame 14. The threaded cylinder 17 that is slidably connected to the driving cylinder 12 is threadedly connected to the outer surface of the threaded rod 13, and the driving ring 18 is fixed to the threaded cylinder 17.

[0036] like Figure 5-Figure 6As shown, the first support frame 9 can limit the driving cylinder 12 to rotate only in the drain pipe 1, and the first support frame 9 also plays a role in supporting and fixing the first motor 8 and other components; the first motor 8 can provide rotational force for the driving cylinder 12, and the motor is of existing technology and will not be described in detail; the second support frame 14 can limit and fix the threaded rod 13, which is inserted into the inner wall of the driving cylinder 12. The driving cylinder 12 is rotatably connected to the threaded rod 13, and the threaded cylinder 17 can be slidably connected to the inner wall of the driving cylinder 12 left and right, that is, when the driving cylinder 12 rotates, it can drive the threaded cylinder 17 to rotate; when the first motor 8 is started, it can drive the corresponding threaded cylinder 17 to rotate, and when the threaded cylinder 17 rotates, the driving cylinder 12 will rotate, and when the threaded cylinder 17 rotates, it can move left or right while rotating through the threaded connection with the threaded rod 13, that is, the driving ring 18 moves left or right while rotating.

[0037] The right end surface of the drive ring 18 is hinged with two centrally symmetrical pawls 20, and the right end surface of the drive ring 18 is also fixed with two elastic sheets 21 that cooperate with the corresponding pawls 20. The right end surface of the drive ring 18 is also rotatably connected to a ratchet 19 that cooperates with the pawl 20, and the arc scrapers 25 are respectively installed on the corresponding ratchet wheels 19.

[0038] like Figure 5-Figure 7 As shown, the pawl 20 can drive the driving ring 18, and when the threaded cylinder 17 rotates, it can drive the corresponding driving ring 18 to rotate, and when the driving ring 18 rotates, it will drive the corresponding pawl 20 to rotate in a circle. By setting the elastic piece 21, the two pawls 20 can be driven to always be at the outermost end, even if the pawl 20 is engaged with the ratchet 19 under normal conditions; when the threaded cylinder 17 rotates forward, the threaded cylinder 17 and the driving ring 18 can be moved to the right while rotating forward. At this time, the arc scraper 25 is in an open state, that is, the arc scraper 25 can scrape the inner wall of the drain pipe 1 when moving to the right, and when the driving ring 18 rotates forward, it will drive the corresponding pawl 20 to rotate in a circle, and the pawl 20 rotates in a circle and drives the corresponding When the ratchet 19 rotates, the corresponding arc scraper 25 is driven to rotate and move to the right, that is, the inner wall of the drain pipe 1 is cut, scraped, etc.; when the threaded barrel 17 rotates in the opposite direction, the corresponding threaded barrel 17 and the drive ring 18 can be reversed and moved to the left to reset. When the drive ring 18 reverses, the pawl 20 can be driven to reverse. When the pawl 20 reverses, it will slide relative to the ratchet 19, that is, the pawl 20 no longer drives the ratchet 19 to rotate. At this time, the corresponding ratchet 19 and the arc scraper 25 can only follow the drive ring 18, ratchet 19, etc. to move to the left to reset, and no longer follow the drive ring 18 to rotate. When resetting, the arc scraper 25 no longer rotates to do work, further reducing energy consumption.

[0039] Four evenly distributed extension cylinders 22 are fixed to the outer surface of the ratchet 19, and the inner walls of the extension cylinders 22 are slidably connected to movable connecting rings 27, and the inner walls of the connecting rings 27 are rotatably connected to extension rods 23. The outer end surfaces of the extension rods 23 are respectively fixed with arc-shaped support seats 24, and the arc-shaped scrapers 25 are respectively fixed to the inner walls of the corresponding arc-shaped support seats 24. The inner walls of the inner ends of the extension rods 23 are respectively fixed with first sliding pins 29, and the left and right ends of the outer surface of the extension cylinder 22 are respectively provided with oblique arc grooves 31 that cooperate with the first sliding pins 29.

[0040] like Figure 7-12 As shown, the connecting ring 27 can move inward or outward on the inner wall of the extension tube 22, and is connected to the inner wall of the connecting ring 27 by rotating the extension rod 23. When the connecting ring 27 moves, it can drive the extension rod 23 to move, and the extension rod 23 can also rotate, and the two do not affect each other; the extension rod 23 passes through the outer end surface of the extension tube 22, and can slide inward or outward on the inner wall of the extension tube 22 and can rotate; the arc support seat 24 is used to support and fix the arc scraper 25, and the serrations 26 are evenly fixed on the arc scraper 25; the installation and shape of the first sliding pin 29 and the oblique arc groove 31 are as shown Figure 11 or Figure 12 As shown, when the connecting ring 27 moves inward, it can drive the corresponding extension rod 23, the arc-shaped support seat 24, the arc-shaped scraper 25, the serrations 26, etc. to move inward synchronously, that is, the arc-shaped scraper 25 retracts inward and disengages from the inner wall of the drain pipe 1. When the extension rod 23 moves inward, it drives the first sliding pin 29 to move inward. When the first sliding pin 29 moves inward, it engages with the oblique arc groove 31, causing the first sliding pin 29 to move inward while rotating, which can make the extension rod 23, the arc-shaped scraper 25, etc. move inward while rotating. When the connecting ring 27 moves inward to the bottom, the corresponding first sliding pin 29 will move inward to the bottommost state and rotate 90 degrees, that is, the corresponding arc scraper 25 moves inward to the bottommost state and rotates 90 degrees, that is, it is completely out of contact with the inner wall of the drain pipe 1 and rotates from a horizontal state to a vertical state. At this time, the arc scraper 25 moves to the left and resets, and the action surface with water is smaller, which will greatly reduce the resistance, and the serrations 26 can be continuously flushed under the flushing of the water flow to prevent impurities from being stuck in the serrations 26.

[0041] The end surfaces of both sides of the extension tube 22 are respectively slidably connected with control plates 41 that can move left and right, and the two ends of the outer surface of the connecting ring 27 are respectively fixed with extension pins 28. The control plate 41 is respectively provided with control grooves that match the extension pin 28. The control grooves include an upper transverse groove 42, an oblique groove 43 and a lower transverse groove 44. When the control plate 41 moves, the connecting ring 27 can be at the outermost end through the engagement of the upper transverse groove 42 with the extension pin 28, and can be moved inward or outward through the engagement of the oblique groove 43 with the extension pin 28. The connecting ring 27 can be at the innermost end through the engagement of the lower transverse groove 44 with the extension pin 28.

[0042] like Figures 9-12 As shown, the control plate 41 can move left and right on the inner walls of the two ends of the extension tube 22. Long key grooves 30 are respectively opened on the end surfaces of the extension tube 22. The extension pins 28 are respectively slidably connected to the inner walls of the long key grooves 30. The limit connecting ring 27 and the long key groove 30 can only move inward or outward; the installation and shape of the upper transverse groove 42, the oblique key groove 49, the lower transverse groove 44 and the extension pin 28 are as shown. Figure 9 or Figure 10 As shown, when the extension pin 28 is on the inner wall of the upper transverse groove 42, the movement of the extension pin 28, the connecting ring 27, etc. can be restricted when the control plate 41 does not move, that is, the connecting ring 27 is stable at the outermost end position; when the extension pin 28 is engaged with the inner wall of the lower transverse groove 44, the movement of the extension pin 28, the connecting ring 27, etc. can be restricted when the control plate 41 does not move, that is, the connecting ring 27 is stable at the innermost end position; when the control plate 41 moves to one side, the upper transverse groove 42, the inclined slide groove 43, the lower transverse groove 44 and the extension pin 28 are engaged, which can make the extension pin 28 and the connecting ring 27 move inward or outward, that is, the extension pin 28, the connecting ring 27, and the arc scraper 25 move inward or outward by moving the control plate 41.

[0043] The right end of the outer surface of the extension tube 22 is fixedly connected to a first extension seat 32, and the right end surface of the two control panels 41 is fixedly connected to a first connecting seat 34. The first extension seat 32 is fixedly connected to a first spring 33 that cooperates with the first connecting seat 34. The left end of the extension tube 22 is provided with an end point locking device that cooperates with the control panel 41, and the left end of the second support frame 14 is provided with a second circular stop pad 15 that cooperates with the first connecting seat 34.

[0044] like Figure 5 、 Figure 9-10As shown, the first extension seat 32 is used to support and fix the first spring 33, and the first spring 33 always has a rightward thrust on the first connecting plate, even if the two control plates 41 are in the rightmost end state under normal circumstances, that is, the two corresponding arc scrapers 25 are in the outermost end state under normal circumstances; when the threaded cylinder 17, the extension cylinder 22, the arc scraper 25, etc. move from left to right, that is, the arc scraper 25 is in the outermost end under normal circumstances, it can scrape the inner wall of the drain pipe 1, and the right end surface of the second support frame 14 is fixedly connected to four evenly distributed second guide rods 16, and the right end surface of the second guide rod 16 is fixedly connected to a second circular stop washer 15, which is equivalent to the second circular stop washer 15 being fixed to the second support frame 14; when the first connecting seat 34 moves to the top position to the right, that is, when the first connecting seat 34 contacts the second circular stop washer 15, the corresponding second circular stop washer 15 and the control plate 41 no longer move, and at this time the threaded cylinder 17, the ratchet When the wheel 19, extension tube 22, etc. continue to move to the right, the extension tube 22 will slide relative to the control plate 41, and will compress the first spring 33. The extension pin 28 will move from the outermost end to the innermost end under the engagement of the control groove. At this time, the corresponding extension rod 23 and arc scraper 25 will be driven to move inward while rotating, that is, the arc scraper 25 moves to the innermost end position and rotates 90 degrees, which can reduce the water flow resistance when moving to the left and resetting; through the provided end point locking device, when the extension tube 22 moves to the rightmost end of the control plate 41, that is, the arc scraper 25 moves to the innermost end and rotates 90 degrees, the end point locking device can be opened, and after the end point locking device is opened, the position of the control plate 41 can be locked, that is, the arc scraper 25 can be at the innermost end and in a vertical state under normal conditions, even if the device keeps the arc scraper 25 in a stable state when moving to the left and resetting.

[0045] The end point locking device includes a second extension seat 35 fixed to the extension tube 22, and two side plates 36 are slidably connected to the second extension seat 35. Wedge-shaped blocks 37 are respectively fixed to the outer end surfaces of the two side plates 36. The left end surfaces of the two control plates 41 are each fixed with a second connecting seat 40, and the inner walls of the second connecting seat 40 are respectively provided with a card groove 50 that cooperates with the wedge-shaped block 37. The second extension seat 35 is also fixed with a U-shaped support seat 45, and the upper and lower end surfaces of the U-shaped support seat 45 are respectively slidably connected to a reset plate 47 that can move left and right. The upper and lower end surfaces of the side plates 36 are respectively fixed with a second sliding pin 48, and the reset plate 47 is respectively provided with an oblique key groove 49 that cooperates with the second sliding pin 48.

[0046] like Figure 13-15As shown, the side plate 36 can be slidably connected to the second extension seat 35 in the front and rear direction. The inner walls of the second extension seat 35 and the U-shaped support seat 45 are respectively fixed with spring baffles 38. The end surfaces of the two sides of the spring baffles 38 are respectively fixed with second springs 39. The outer ends of the two second springs 39 are respectively fixed with the side plates 36. The second springs 39 are provided to enable the side plates 36 to always have a driving force to the outside. The wedge-shaped block 37, the second connecting seat 40, and the card slot 50 are installed and shaped as shown in FIG. Figure 15 As shown, when the second connecting seat 40 moves to the left on the outer end surface of the side plate 36, the slot 50 can meet the wedge-shaped block 37. After the slot 50 meets the wedge-shaped block 37, the second connecting seat 40 continues to move to the left. Under the action of the inclined surface of the wedge-shaped block 37, the wedge-shaped block 37 and the side plate 36 can move inward. The inward movement of the side plate 36 will compress the second spring 39. When the second connecting seat 40 moves to the left so that the slot 50 is out of contact with the wedge-shaped block 37, the side plate 36 will be in the first Under the elastic force of the second spring 39, it moves outward and resets, that is, the corresponding wedge-shaped block 37 moves outward and resets. When the wedge-shaped block 37 moves outward and resets, the wedge-shaped block 37 will block the second connecting seat 40, that is, prevent the second connecting seat 40 from moving rightward and resetting, that is, the end locking device is opened. At this time, the second connecting seat 40, the control plate 41, etc. are at the left end position of the extension tube 22, that is, the arc scraper 25 is in the retracted state; the installation and shape of the reset plate 47, the oblique keyway 49, and the second sliding pin 48 are as shown in FIG. Figure 13 When the second connecting seat 40 is disengaged from the second connecting seat 40, the wedge-shaped block 37 no longer blocks the second connecting seat 40. The second connecting seat 40, the control plate 41 and the first connecting seat 34 will move to the right and reset under the elastic force of the first spring 33. That is, under the engagement of the control groove and the extension pin 28, the corresponding arc scraper 25 will be driven to move outward and unfold, and rotate 90 degrees to a horizontal state, which is convenient for cleaning the drain pipe 1.

[0047] A U-shaped guide plate 46 is fixedly connected to the left end surface of each of the two reset plates 47 , and a first circular stop washer 11 matched with the U-shaped guide plate 46 is fixedly connected to the right side of the first support frame 9 .

[0048] like Figure 5 、 Figure 13As shown, four evenly distributed first guide rods 10 are fixed to the right end surface of the first support frame 9, and the first circular stop pad 11 is fixed to the first guide rod 10, which is equivalent to the first circular stop pad 11 being fixed to the first support frame 9. Through the cooperation of the U-shaped guide plate 46 and the first support frame 9, when the extension cylinder 22, the arc scraper 25, the U-shaped guide plate 46, etc. are synchronously moved to the left at the top, that is, when the U-shaped guide plate 46 contacts the first circular stop pad 11, the U-shaped guide plate 46 is blocked and restricted from moving, and the corresponding extension cylinder 22, the arc scraper 25, the U-shaped guide plate 46 and the like are synchronously moved to the left at the top, that is, when the U-shaped guide plate 46 contacts the first circular stop pad 11, the U-shaped guide plate 46 is blocked and restricted from moving. When the left side is further moved, the two side plates 36 will move inward, and the corresponding trapezoidal blocks will be out of contact with the second connecting seat 40, that is, they will no longer block the second connecting seat 40. The second connecting seat 40 will move to the right and reset under the elastic force of the first spring 33. At this time, the arc scraper 25 will move upward while rotating, so as to be in a horizontal expanded state again, that is, it can scrape the inner wall of the drain pipe 1 again; that is, when the driving cylinder 12 rotates forward, the arc scraper 25 can rotate while rotating through the engagement of the threaded rod 13 and the threaded cylinder 17. Move to the right, at this time the curved scraper 25 is in a horizontal state and in an expanded state at the outermost end, and can scrape the inner wall of the drain pipe 1. When the curved scraper 25 moves to the right at the top position, that is, when the first connecting seat 34 contacts the inner wall of the second circular ring pad, the control plate 41 and the extension pin 28 are engaged, and the curved scraper 25 can be moved inward while rotating 90 degrees. The curved scraper 25 can be separated from the contact with the drain pipe 1 when moving inward, preventing impurities from being scraped back and reducing friction loss. After rotating 90 degrees, the curved scraper When 25 moves to the left and resets, it can reduce the water flow resistance, thereby reducing the power consumption. When the driving cylinder 12 is reversed, the arc scraper 25 can move to the left and reset. When the arc scraper 25 and the U-shaped guide plate 46 move to the left and contact with the second circular ring gasket, the two trapezoidal blocks can be driven to move inward, that is, the corresponding short-point locking device is closed. At this time, the arc scraper 25 can move outward and rotate 90 degrees, that is, it is in a horizontally expanded state, and contacts the inner wall of the drain pipe 1 again. It can be recycled over and over again, and no further details will be given.

[0049] The drainage pipe 1 includes a water inlet and a water outlet, one end of the water inlet is fixedly connected to a limit seat 2, the lower end surface of the limit seat 2 is fixedly connected to a multi-stage telescopic rod 3, the lower end surface of the multi-stage telescopic rod 3 is fixedly connected to an installation box 4, and the left and right ends of the installation box 4 are respectively provided with a first rotating shaft 5, and the outer surface of the first rotating shaft 5 is respectively fixedly connected to a rotatable impeller 6.

[0050] like Figure 3-Figure 4As shown, a float 7 is also provided on the first rotating shaft 5. The float 7 has a certain buoyancy in the water, which can keep the impeller 6 on the water level at all times, making it easier for the water flow to drive the impeller 6 to rotate. When the water level reaches the specified height, it can flow from the water inlet into the drain pipe 1 and out from the water outlet. When the water flows, it can drive the impeller 6 and the first rotating shaft 5 to rotate; the limit seat 2 is used to support and fix the multi-stage telescopic rod 3. Through the limit of the multi-stage telescopic rod 3, the installation box 4, the first rotating shaft 5, the impeller 6, etc. can only move up and down at the specified position; a generator and a battery are provided in the installation box 4, and the generator and the battery are electrically connected to the first motor 8. The first rotating shaft 5 is installed on the generator. When the impeller 6 rotates, the generator can generate electricity and store energy. The battery provides electrical energy for the first motor 8. The generator and the battery are existing technologies and will not be described in detail.

[0051] When the present invention is in use, when the arc scraper 25 is unfolded, the arc scraper 25 can contact the inner wall of the drain pipe 1. When the drive cylinder 12 rotates, it can drive the corresponding drive ring 18, the arc scraper 25, the saw teeth 26, etc. to rotate and move synchronously to one side. When the arc scraper 25 is in the open state and in contact with the inner wall of the drain pipe 1, the arc scraper 25 can scrape the inner wall of the drain pipe 1, thereby cleaning the impurities adhering to the drain pipe 1, and when the saw teeth 26 rotate and move, it can better clean the impurities adhering to the inner wall of the drain pipe 1, and the saw teeth 26 can cut the impurities when rotating and moving. The arc scraper 25 can scrape impurities more smoothly, and the small pieces of impurities after being cut can be more easily flushed out of the drain pipe 1 under the impact of the water flow; when the drive ring 18 moves to the left to the top, the arc scraper 25 can move outward, that is, the arc scraper 25 contacts the inner wall of the drain pipe 1, and the drain pipe 1 can be scraped when the arc scraper 25 moves. When the drive ring 18 moves to the right to the top, the arc scraper 25 can be driven to rotate and move inward, so that the arc scraper 25 is in a retracted state, and when it rotates to the specified position, it can reduce the resistance of the water flow, that is, reduce energy consumption when resetting to one side.

Persons skilled in the art may make various modifications, additions, or substitute similar methods to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
