[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1, reference Figure 1 to Figure 16 , which is the first embodiment of the present invention, and this embodiment provides a sludge removal device for water conservancy projects. The sludge removal device for water conservancy projects includes a main component 100, including a storage box 101, a drainage pipe 102, a support leg 103, a sewage pipe 104, a slurry inlet pipe 105 and a sludge filter cloth 106. The drainage pipe 102 and the sewage pipe 104 are both fixed to the bottom of the storage box 101 and are connected to the storage box 101. The support leg 103 is fixed to the bottom of the storage box 101 for supporting the storage box 101. The slurry inlet pipe 105 is fixed to the top of the storage box 101, and the sludge filter cloth 106 is fixed to the inner bottom wall of the storage box 101.

[0036] The storage box 101 is arranged on the bank of the dredging site. The mud water can be transported to the storage box 101 through the slurry inlet pipe 105 by a mud pump, so that the sludge can be treated on site. The drain pipe 102 is used to discharge the water separated from the sludge in the storage box 101. The support legs 103 are used to fix and support the storage box 101. The sewage pipe 104 is used to discharge the sludge after the water is separated. The sludge filter cloth 106 is used to squeeze and filter the sludge to obtain sludge with less water.

[0037] The adjustment assembly 200 is arranged on the storage box 101, and includes a lifting platform 201a sliding in the storage box 101, a guide tube 201b is fixed on the top of the lifting platform 201a, a first spring 201c is arranged in the guide tube 201b, a support ring 201d is fixed on the top of the storage box 101, a support column 201e is fixed on the top of the support ring 201d, a support plate 201f is fixed on the top of the support column 201e, two ends of the first spring 201c are respectively fixed to the top of the lifting platform 201a and the bottom of the support plate 201f, a metal tube 201g is fixed on the top of the lifting platform 201a, and a through hole 201a-1 is opened on the surface of the lifting platform 201a. 1a-1 is located below the metal pipe 201g, a delivery pipe 201h is fixed at the bottom of the lifting platform 201a, an extrusion plate 201i is fixed at the bottom of the delivery pipe 201h, a sealing cylinder 201j is fixed at the top of the extrusion plate 201i, the top of the sealing cylinder 201j is fixed to the bottom of the lifting platform 201a, a support rod 201k is fixed at the top of the extrusion plate 201i, and the other end of the support rod 201k is fixed to the bottom of the lifting platform 201a, a sealing ring 201l is fixed in the delivery pipe 201h, a rotating shaft 201m is rotatably connected in the delivery pipe 201h, a butterfly valve 201n is fixed at the end of the rotating shaft 201m, and the sludge filter cloth 106 is fixed to the bottom of the extrusion plate 201i.

[0038] The first spring 201c is in a stretched state, the support plate 201f is used to fix and support the first spring 201c, the lifting platform 201a is used to support the sludge transported to the storage box 101 by the slurry inlet pipe 105, and a plurality of holes are opened on the surface of the metal pipe 201g, and the surface of the metal pipe 201g is covered with a filter cloth, so that the moisture in the sludge can enter the metal pipe 201g through the filter cloth, and the moisture is transported by the metal pipe 201g so that the moisture enters the bottom of the lifting platform 201a through the through hole 201a-1. The sealing cylinder 201j is set between the lifting platform 201a and the extrusion plate 201i to form a sealed space, thereby storing the water flowing down from the through hole 201a-1.

[0039] The switch of the butterfly valve 201n can be controlled by rotating the rotating shaft 201m. The setting of the sealing ring 201l enables the butterfly valve 201n to seal the delivery pipe 201h. When the delivery pipe 201h is in a sealed state, the sludge on the top of the lifting platform 201a can squeeze the lifting platform 201a, so that the lifting platform 201a moves downward, so that the lifting platform 201a stretches the first spring 201c. At this time, the lifting platform 201a can squeeze the extrusion plate 201i through the sealing cylinder 201j and the support rod 201k, so that the extrusion plate 201i moves downward. Since the butterfly valve 201n is closed at this time, the sludge in the sludge filter cloth 106 is squeezed, so that the moisture in the sludge in the sludge filter cloth 106 is squeezed out and discharged through the drain pipe 102 at the bottom of the storage box 101.

[0040] When the butterfly valve 201n is opened, the sludge on the top of the lifting platform 201a can flow downward. At this time, the pressure of the sludge on the lifting platform 201a is reduced. Under the pulling force of the first spring 201c, the lifting platform 201a can move upward to reset.

[0041] Specifically, the adjustment component 200 also includes a cleaning part 202, which is arranged on the extrusion plate 201i, including a water pipe 202a fixed in the extrusion plate 201i, an adjustment frame 202b is fixed on the top of the extrusion plate 201i, the end of the water pipe 202a is fixed in the adjustment frame 202b, and the other end of the water pipe 202a points to the outer surface of the sludge filter cloth 106, and an adjustment ring 202c is slidably connected in the adjustment frame 202b, and a through groove 202c-1 is opened on the surface of the adjustment ring 202c.

[0042] By moving the adjusting ring 202c, the through groove 202c-1 on the surface of the adjusting ring 202c can be connected to the end of the water pipe 202a, so that the water on the top of the extrusion plate 201i enters the water pipe 202a through the adjusting frame 202b, and then flushes to the outer surface of the sludge filter cloth 106 from the other end of the water pipe 202a, thereby cleaning the sludge filter cloth 106.

[0043] Specifically, the adjustment component 200 also includes a seal 203, which is arranged in the sewage pipe 104, including a sealing block 203a fixed to the inner wall of the sewage pipe 104, a rotating rod 203b is rotatably connected in the sewage pipe 104, a switch block 203c is fixed on the surface of the rotating rod 203b, a hanging block 203d is fixed at the bottom of the storage box 101, and the rotating rod 203b is rotatably connected in the hanging block 203d.

[0044] The sealing block 203a is used to cooperate with the switch block 203c to control the on and off of the sewage pipe 104. By rotating the rotating rod 203b, the switch block 203c can be driven to rotate so that the switch block 203c is away from one of the sealing blocks 203a. At this time, the sludge in the sewage pipe 104 can be discharged through between the sealing block 203a and the switch block 203c.

[0045] Example 2, reference Figure 1 to Figure 16 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0046] Specifically, the adjustment component 200 also includes an adjustment member 204, which is arranged on the storage box 101, including a top support seat 204a fixed to the surface of the storage box 101, a bottom support seat 204b fixed to one side of the support leg 103, and an adjustment column 204c rotatably connected to the top support seat 204a and the bottom support seat 204b.

[0047] With the support of the top support seat 204a and the bottom support seat 204b, the adjustment column 204c can be stably rotated in situ, and the adjustment column 204c will not move up and down.

[0048] Specifically, a lifting frame 204d is fixed to one side of the extrusion plate 201i, a guide block 204e slides inside the lifting frame 204d, a second spring 204f is arranged inside the guide block 204e, and two ends of the second spring 204f are respectively fixed to the inner wall of the lifting frame 204d and the inner wall of the guide block 204e.

[0049] The lifting frame 204d is used to support the guide block 204e. The second spring 204f is in a compressed state and is used to push the guide block 204e. When the extrusion plate 201i is lifted or lowered, the lifting frame 204d can be driven to move synchronously, so that the end of the guide block 204e can slide in the adjustment column 204c.

[0050] Specifically, a first bevel gear 204g is fixed on the surface of the adjusting column 204c, a second bevel gear 204h is fixed on the surface of the rotating rod 203b, a first slide groove 204c-1, a second slide groove 204c-2, a third slide groove 204c-3, a fourth slide groove 204c-4, a fifth slide groove 204c-5 and a sixth slide groove 204c-6 are provided on the surface of the adjusting column 204c, an end of the guide block 204e slides in the above six slide grooves, and a corrugated plate 204i is fixed to the bottom of the lifting frame 204d.

[0051] The corrugated plate 204i can prevent water in the storage box 101 from splashing out. The first bevel gear 204g and the second bevel gear 204h are engaged, so that the adjustment column 204c rotates to drive the rotating rod 203b to rotate, thereby the rotating rod 203b drives the switch block 203c to rotate.

[0052] When the extrusion plate 201i moves downward, the end of the guide block 204e first slides from the first slide groove 204c-1 to the second slide groove 204c-2.

[0053] When the end of the guide block 204e slides downward in the first slide groove 204c-1, the guide block 204e does not drive the adjusting column 204c to rotate. At this time, the squeezing plate 201i squeezes the sludge filter cloth 106, so that the sludge in the sludge filter cloth 106 is separated from the water.

[0054] When the end of the guide block 204e slides from the first slide groove 204c-1 to the second slide groove 204c-2, the guide block 204e starts to drive the adjusting column 204c to rotate, and the adjusting column 204c can drive the switch block 203c to rotate. At this time, the sewage pipe 104 can be opened, so that the sludge under the sludge filter cloth 106 is squeezed and discharged from the sewage pipe 104. At this time, the opening of the sewage pipe 104 gradually increases, and as the squeezing plate 201i squeezes the sludge filter cloth 106, water in the sludge will still be separated.

[0055] When the end of the guide block 204e slides from the second slide groove 204c-2 to the third slide groove 204c-3, the opening of the sewage pipe 104 is the largest. At this time, the guide block 204e slides downward in the third slide groove 204c-3 to keep the opening of the sewage pipe 104 at the largest, so that the sludge under the sludge filter cloth 106 is stably squeezed and discharged from the sewage pipe 104.

[0056] When the end of the guide block 204e slides from the third slide groove 204c-3 to the fourth slide groove 204c-4, the guide block 204e can drive the adjustment column 204c to reset and rotate, so that the switch block 203c starts to reset, thereby gradually reducing the opening of the sewage pipe 104.

[0057] When the end of the guide block 204e slides from the fourth slide groove 204c-4 to the fifth slide groove 204c-5, the sewage pipe 104 has been closed, and the sludge is no longer discharged. As the squeezing plate 201i moves downward, the sludge moisture in the sludge filter cloth 106 is separated again.

[0058] When the guide block 204e moves downward in the fifth slide groove 204c-5, the switch member 205 can open the butterfly valve 201n, so that the sludge in the conveying pipe 201h can enter the sludge filter cloth 106. At this time, the lifting platform 201a can move upward through the reset tension of the first spring 201c, thereby driving the extrusion plate 201i to move upward, so that the guide block 204e slides from the fifth slide groove 204c-5 to the sixth slide groove 204c-6. As the extrusion plate 201i moves upward, the guide block 204e slides from the sixth slide groove 204c-6 to the first slide groove 204c-1.

[0059] The slot depths of the fifth slide groove 204c-5 and the sixth slide groove 204c-6 are greater than the slot depth of the fourth slide groove 204c-4, so that the guide block 204e can only slide from the fifth slide groove 204c-5 to the sixth slide groove 204c-6.

[0060] The groove depth at the connection between the first slide groove 204c-1 and the second slide groove 204c-2 is greater than the groove depth of the sixth slide groove 204c-6 on one side thereof, so that the guide block 204e can only move from the first slide groove 204c-1 to the second slide groove 204c-2.

[0061] Specifically, the adjustment component 200 also includes a switch member 205, which is arranged on the adjustment member 204, including a lifting rod 205a sliding in the lifting frame 204d, a lifting ring 205b is fixed on the top of the lifting rod 205a, and a connecting rod 205c is fixed on the bottom of the lifting rod 205a.

[0062] The lifting rod 205a is used to support the lifting ring 205b so that the lifting ring 205b can be lifted and lowered stably. The connecting rod 205c is used to connect multiple lifting rods 205a, thereby improving the stability of the lifting rods 205a.

[0063] Specifically, a fixed rod 205d is fixed on the surface of the lifting ring 205b, a rack 205e is fixed to the end of the fixed rod 205d, a first adjusting gear 205f and a second adjusting gear 205g are fixed to the surface of the rotating shaft 201m, the first adjusting gear 205f and the rack 205e are meshed, a toothed plate 205h is fixed on the top of the adjusting ring 202c, and the second adjusting gear 205g and the toothed plate 205h are meshed.

[0064] By rising the lifting ring 205b, the fixed rod 205d can be driven to move upward, so that the fixed rod 205d drives the first adjusting gear 205f to rotate through the rack 205e, so that the rotating shaft 201m drives the butterfly valve 201n to rotate, thereby opening the butterfly valve 201n, so that the sludge in the conveying pipe 201h can enter the sludge filter cloth 106.

[0065] When the rotating shaft 201m rotates, it can drive the second adjusting gear 205g to rotate, so that the second adjusting gear 205g drives the tooth plate 205h to move, and the tooth plate 205h drives the adjusting ring 202c to move, so that the through groove 202c-1 on the adjusting ring 202c is connected to the end of the water pipe 202a, so that the water on the top of the extrusion plate 201i enters the water pipe 202a through the adjusting frame 202b, and then flushes from the other end of the water pipe 202a to the outer surface of the sludge filter cloth 106, so as to clean the sludge filter cloth 106.

[0066] Specifically, a positioning column 205i is fixed at the bottom of the lifting ring 205b, and the other end of the positioning column 205i is fixed to the top of the connecting rod 205c. A positioning groove 205i-1 is opened on the surface of the positioning column 205i. There are two positioning grooves 205i-1, which are respectively arranged at both ends of the positioning column 205i. A clamping block 205j is clamped in the positioning groove 205i-1, a positioning block 205k is fixed on one side of the clamping block 205j, and a driving sleeve 205l is fixed on one side of the clamping block 205j. A third spring 205m is arranged in the driving sleeve 205l.

[0067] The third spring 205m is in a compressed state. The reset elastic force of the third spring 205m can enable the driving sleeve 205l to drive the clamping block 205j away from the positioning groove 205i-1, thereby releasing the limit on the positioning column 205i, so that the positioning column 205i can slide in the lifting frame 204d, and the positioning block 205k slides on the surface of the adjusting column 204c.

[0068] Specifically, a lifting groove 204c-7 is provided on the surface of the adjusting column 204c, a lifting sleeve 205n slides in the lifting groove 204c-7, a fourth spring 205o is arranged in the lifting sleeve 205n, a driving block 205p is fixed on the surface of the lifting sleeve 205n, a placement groove 204c-8 is provided on the surface of the adjusting column 204c, and the positioning block 205k can be moved into the placement groove 204c-8.

[0069] The upper and lower sides of the adjusting column 204c are provided with lifting sleeves 205n, a fourth spring 205o, a driving block 205p and a placement groove 204c-8 in opposite directions, and the fourth spring 205o is in a compressed state.

[0070] When the extrusion plate 201i moves downward, the lifting frame 204d can drive the lifting ring 205b to move toward the driving block 205p under the adjusting column 204c, so that the lifting ring 205b squeezes the driving block 205p, thereby compressing the fourth spring 205o. When the positioning block 205k moves to the side of the placement groove 204c-8 under the adjusting column 204c, the positioning block 205k can be moved into the placement groove 204c-8 under the thrust of the third spring 205m. At this time, the clamping block 205j is away from the positioning groove 205i-1, thereby releasing the restriction on the positioning column 205i. At this time, under the action of the reset elastic force of the fourth spring 205o, the driving block 205p can drive the lifting ring 205b to move upward, so that the connecting rod 205c moves to the bottom of the lifting frame 204d. During the upward movement of the lifting ring 205b, the butterfly valve 201n can be opened, so that the sludge in the conveying pipe 201h can enter the sludge filter cloth 106, and at the same time, the water on the top of the extrusion plate 201i enters the water pipe 202a through the regulating frame 202b, and then flushes to the outer surface of the sludge filter cloth 106 from the other end of the water pipe 202a, so as to clean the sludge filter cloth 106.

[0071] During the upward movement of the lifting ring 205b, the positioning block 205k moves into the placement groove 204c-8, making the lifting frame 204d unable to move relative to the adjusting column 204c, thereby positioning the extrusion disk 201i. As the lifting ring 205b rises, another positioning groove 205i-1 on the surface of the positioning column 205i will move to the side of the clamping block 205j. At this time, the extrusion disk 201i will move upward under the pulling force of the first spring 201c, so that the positioning block 205k can be moved out of the placement groove 204c-8 through the inclined squeezing of the placement groove 204c-8 under the adjusting column 204c. At this time, the positioning block 205k can push the clamping block 205j to move into the positioning groove 205i-1, thereby positioning the positioning column 205i, so that there will be no relative movement between the positioning column 205i and the lifting frame 204d, thereby fixing the opened butterfly valve 201n to prevent the butterfly valve 201n from closing by itself.

[0072] At this time, the extrusion plate 201i will move upward under the pulling force of the first spring 201c, and the lifting frame 204d will rise on the surface of the adjusting column 204c at the same time. When the lifting ring 205b moves to the bottom of the driving block 205p above the adjusting column 204c, the driving block 205p can be pushed to move the driving block 205p upward, so that the corresponding fourth spring 205o is compressed. When the positioning block 205k rises to the side of the placement groove 204c-8 above the adjusting column 204c, the positioning block 205k can be moved to the placement groove 204c-8 under the pushing force of the third spring 205m. c-8, at this time, the clamping block 205j is away from the positioning groove 205i-1, thereby releasing the limit on the positioning column 205i. At this time, under the action of the reset elastic force of the fourth spring 205o, the driving block 205p can drive the lifting ring 205b to move downward, so that the lifting ring 205b drives the butterfly valve 201n to close, and the water pipe 202a is cut off by the adjusting ring 202c, and the cleaning of the sludge filter cloth 106 is stopped. At this time, the lifting ring 205b falls on the top of the lifting frame 204d, and the positioning groove 205i-1 above the positioning column 205i just moves to the side of the clamping block 205j.

[0073] As the slurry inlet pipe 105 transports muddy water into the storage box 101, the lifting platform 201a drives the extrusion plate 201i to move downward, and the extrusion plate 201i drives the positioning block 205k to move downward through the lifting frame 204d, so that the inclined surface below the placement groove 204c-8 squeezes the positioning block 205k, so that the clamping block 205j moves into the positioning groove 205i-1. At this time, the positioning block 205k can slide downward on the surface of the adjusting column 204c.

[0074] When in use, the current state shown in the figure is the state of the lifting platform 201a moving downward. As the slurry inlet pipe 105 transports mud and water into the storage box 101, the load-bearing capacity of the lifting platform 201a becomes larger, thereby driving the extrusion plate 201i to move downward, so that the sludge in the sludge filter cloth 106 is squeezed, thereby squeezing the water in the sludge in the sludge filter cloth 106 and discharging it through the drain pipe 102 at the bottom of the storage box 101. At this time, the end of the guide block 204e slides downward in the first slide groove 204c-1.

[0075] As the extrusion plate 201i moves downward, the end of the guide block 204e slides from the first slide groove 204c-1 to the second slide groove 204c-2, and then slides from the second slide groove 204c-2 to the third slide groove 204c-3, and then slides from the third slide groove 204c-3 to the fourth slide groove 204c-4, and then slides from the fourth slide groove 204c-4 to the fifth slide groove 204c-5. This process can filter out the moisture in the sludge and discharge the sludge from the sewage pipe 104 until the sewage pipe 104 is closed again.

[0076] When the guide block 204e slides downward in the fifth slide groove 204c-5, the lifting frame 204d drives the lifting ring 205b to move toward the driving block 205p below the adjusting column 204c, so that the lifting ring 205b squeezes the driving block 205p, thereby compressing the fourth spring 205o. When the positioning block 205k moves to the side of the placement groove 204c-8 below the adjusting column 204c, the positioning block 205k can be moved into the placement groove 204c-8 under the thrust of the third spring 205m. At this time, the clamping block 205j is away from the positioning groove 205i-1, thereby releasing the positioning column 204c. 05i is limited. At this time, under the action of the reset elastic force of the fourth spring 205o, the driving block 205p can drive the lifting ring 205b to move upward, so that the connecting rod 205c moves to the bottom of the lifting frame 204d. During the upward movement of the lifting ring 205b, the butterfly valve 201n can be opened, so that the sludge in the conveying pipe 201h can enter the sludge filter cloth 106, and at the same time, the water on the top of the squeezing plate 201i enters the water pipe 202a through the regulating frame 202b, and then flushes from the other end of the water pipe 202a to the outer surface of the sludge filter cloth 106, so as to clean the sludge filter cloth 106.

[0077] During the upward movement of the lifting ring 205b, the positioning block 205k moves into the placement groove 204c-8, making the lifting frame 204d unable to move relative to the adjusting column 204c, thereby positioning the extrusion disk 201i. As the lifting ring 205b rises, another positioning groove 205i-1 on the surface of the positioning column 205i will move to the side of the clamping block 205j. At this time, the extrusion disk 201i will move upward under the pulling force of the first spring 201c, so that the positioning block 205k can be moved out of the placement groove 204c-8 through the inclined squeezing of the placement groove 204c-8 under the adjusting column 204c. At this time, the positioning block 205k can push the clamping block 205j to move into the positioning groove 205i-1, thereby positioning the positioning column 205i, so that there will be no relative movement between the positioning column 205i and the lifting frame 204d, thereby fixing the opened butterfly valve 201n to prevent the butterfly valve 201n from closing by itself.

[0078] At this time, as the extrusion plate 201i rises, the sludge continues to enter the sludge filter cloth 106 from the conveying pipe 201h. During this process, the guide block 204e slides from the fifth slide groove 204c-5 to the sixth slide groove 204c-6, and then slides from the sixth slide groove 204c-6 to the first slide groove 204c-1. As the guide block 204e rises in the first slide groove 204c-1, the lifting ring 205b moves to the bottom of the driving block 205p above the adjusting column 204c, pushing the driving block 205p to move the driving block 205p upward, so that the corresponding fourth spring 205o is compressed. When the positioning block 205k rises to the placement groove 204c-8 above the adjusting column 204c, the lifting ring 205b moves to the bottom of the driving block 205p above the adjusting column 204c. When the lifting and lowering parts are in the upper and lower parts, the lifting and lowering rings 205a and 205b are in the upper and lower parts, respectively. When the lifting and lowering parts are in the upper and lower parts, the lifting and lowering rings 205a and 205b are in the upper and lower parts, respectively. When the lifting and lowering parts are in the upper and lower parts, the lifting and lowering rings 205a and 205b are in the upper and lower parts, respectively. When the lifting and lowering parts are in the upper and lower parts, the lifting and lowering rings 205a and 205b are in the upper and lower parts, respectively. When the lifting and lowering parts are in the upper and lower parts, the lifting and lowering rings 205a and 205b are in the upper and lower parts, respectively.

[0079] As the slurry inlet pipe 105 transports muddy water into the storage box 101, the lifting platform 201a drives the extrusion plate 201i to move downward, and the extrusion plate 201i drives the positioning block 205k to move downward through the lifting frame 204d, so that the inclined surface below the placement groove 204c-8 squeezes the positioning block 205k, so that the clamping block 205j moves into the positioning groove 205i-1. At this time, the positioning block 205k can slide downward on the surface of the adjusting column 204c.

[0080] Through the above technical solution, the gravity of the sludge can be used to apply pressure to the sludge itself, thereby improving the sludge separation efficiency, and the sludge filter cloth 106 can be automatically cleaned to prevent the filter holes of the sludge filter cloth 106 from being blocked.

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.
