[0034] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0035] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those specifically described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0036] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively exclusive of other embodiments.

[0037] Example 1, referring to Figures 1 to 16 , is the first embodiment of the present invention. This embodiment provides a silt removal device for water conservancy projects. The silt removal device for water conservancy projects includes a main body assembly 100, which includes a storage tank 101, a drain pipe 102, support legs 103, a sewage discharge pipe 104, a slurry inlet pipe 105, and a silt filter cloth 106. The drain pipe 102 and the sewage discharge pipe 104 are both fixed to the bottom of the storage tank 101 and communicate with the storage tank 101. The support legs 103 are fixed to the bottom of the storage tank 101 for supporting the storage tank 101. The slurry inlet pipe 105 is fixed to the top of the storage tank 101, and the silt filter cloth 106 is fixed to the inner bottom wall of the storage tank 101.

[0038] The storage tank 101 is arranged on the bank of the silt removal site. Through a slurry pump, the muddy water can be transported into the storage tank 101 through the slurry inlet pipe 105, so as to perform on-site treatment of the silt. The drain pipe 102 is used to discharge the water separated from the silt in the storage tank 101. The support legs 103 are used to fixedly support the storage tank 101. The sewage discharge pipe 104 is used to discharge the sludge after separating the water. The silt filter cloth 106 is used to squeeze and filter the silt, so as to obtain sludge with less water.

[0039] The adjusting assembly 200 is arranged on the storage tank 101 and includes a lifting table 201a that slides within the storage tank 101. A guide pipe 201b is fixed to the top of the lifting table 201a. A first spring 201c is arranged within the guide pipe 201b. A support ring 201d is fixed to the top of the storage tank 101. A support column 201e is fixed to the top of the support ring 201d. A support plate 201f is fixed to the top of the support column 201e. The two ends of the first spring 201c are respectively fixed to the top of the lifting table 201a and the bottom of the support plate 201f. A metal pipe 201g is fixed to the top of the lifting table 201a. A through hole 201a-1 is formed on the surface of the lifting table 201a, and the through hole 201a-1 is located below the metal pipe 201g. A delivery pipe 201h is fixed to the bottom of the lifting table 201a. An extrusion disc 201i is fixed to the bottom of the delivery pipe 201h. A sealing cylinder 201j is fixed to the top of the extrusion disc 201i, and the top of the sealing cylinder 201j is fixed to the bottom of the lifting table 201a. A support rod 201k is fixed to the top of the extrusion disc 201i, and the other end of the support rod 201k is fixed to the bottom of the lifting table 201a. A sealing ring 201l is fixed within the delivery pipe 201h. A rotating shaft 201m is rotatably connected within the delivery pipe 201h. A butterfly valve 201n is fixed to the end of the rotating shaft 201m. The sludge filter cloth 106 is fixed to the bottom of the extrusion disc 201i.

[0040] The first spring 201c is in a stretched state. The support plate 201f is used to fixedly support the first spring 201c. The lifting table 201a is used to support the sludge delivered into the storage tank 101 by the slurry inlet pipe 105. Multiple holes are formed on the surface of the metal pipe 201g, and a filter cloth is coated on the surface of the metal pipe 201g, enabling the water in the sludge to enter the metal pipe 201g through the filter cloth. Through the delivery of the metal pipe 201g, the water passes through the through hole 201a-1 and enters below the lifting table 201a. Due to the arrangement of the sealing cylinder 201j between the lifting table 201a and the extrusion disc 201i, a sealed space can be formed to store the water flowing down from the through hole 201a-1.

[0041] By rotating the rotating shaft 201m, the opening and closing of the butterfly valve 201n can be controlled. The arrangement 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 table 201a can extrude the lifting table 201a, causing the lifting table 201a to move downward, thereby stretching the first spring 201c by the lifting table 201a. At this time, the lifting table 201a can extrude the extrusion disc 201i through the sealing cylinder 201j and the support rod 201k, causing the extrusion disc 201i to move downward. Since the butterfly valve 201n is closed at this time, the sludge within the sludge filter cloth 106 is extruded, and thus the water within the sludge in the sludge filter cloth 106 is extruded out and discharged through the drain pipe 102 at the bottom of the storage tank 101.

[0042] When the butterfly valve 201n is opened, the sludge on the top of the lifting table 201a can flow downward. At this time, the pressure of the sludge on the lifting table 201a decreases. Under the pulling force of the first spring 201c, the lifting table 201a can move upward to reset.

[0043] Specifically, the adjusting assembly 200 further includes a cleaning member 202, which is arranged on the extrusion disc 201i and includes a water delivery pipe 202a fixed in the extrusion disc 201i. A regulating frame 202b is fixed on the top of the extrusion disc 201i. The end of the water delivery pipe 202a is fixed in the regulating frame 202b. The other end of the water delivery pipe 202a points to the outer surface of the sludge filter cloth 106. A regulating ring 202c is slidably connected in the regulating frame 202b, and a through groove 202c-1 is formed on the surface of the regulating ring 202c.

[0044] By moving the regulating ring 202c, the through groove 202c-1 on the surface of the regulating ring 202c can be communicated with the end of the water delivery pipe 202a, so that the water on the top of the extrusion disc 201i enters the water delivery pipe 202a through the regulating frame 202b, and then flushes from the other end of the water delivery pipe 202a to the outer surface of the sludge filter cloth 106, thereby cleaning the sludge filter cloth 106.

[0045] Specifically, the adjusting assembly 200 further includes a sealing member 203, which is arranged in the sewage discharge pipe 104 and includes a sealing block 203a fixed on the inner wall of the sewage discharge pipe 104. A rotating rod 203b is rotatably connected in the sewage discharge pipe 104. A switch block 203c is fixed on the surface of the rotating rod 203b. A lifting block 203d is fixed at the bottom of the storage tank 101, and the rotating rod 203b is rotatably connected in the lifting block 203d.

[0046] The sealing block 203a is used to cooperate with the switch block 203c to control the on-off of the sewage discharge pipe 104. By rotating the rotating rod 203b, the switch block 203c can be driven to rotate, so that the switch block 203c moves away from one of the sealing blocks 203a. At this time, the sludge in the sewage discharge pipe 104 can be discharged through the gap between the sealing block 203a and the switch block 203c.

[0047] Example 2, refer to Figures 1 to 16 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0048] Specifically, the adjusting assembly 200 further includes an adjusting member 204, which is arranged on the storage tank 101 and includes a top support seat 204a fixed on the surface of the storage tank 101. A bottom support seat 204b is fixed on one side of the support leg 103. An adjusting column 204c is rotatably connected in the top support seat 204a and the bottom support seat 204b.

[0049] Supported by the top support base 204a and the bottom support base 204b, the adjusting column 204c can rotate stably in place, and the adjusting column 204c will not move up and down.

[0050] Specifically, a lifting frame 204d is fixed on one side of the extrusion disc 201i. A guide block 204e slides in the lifting frame 204d. A second spring 204f is arranged in the guide block 204e. Both ends of the second spring 204f are fixed to the inner wall of the lifting frame 204d and the inner wall of the guide block 204e respectively.

[0051] 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 disc 201i moves up and down, it can drive the lifting frame 204d to move synchronously, so that the end of the guide block 204e can slide in the adjusting column 204c.

[0052] 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. First chutes 204c-1, 204c-2, 204c-3, 204c-4, 204c-5 and sixth chutes 204c-6 are formed on the surface of the adjusting column 204c. The end of the guide block 204e slides in the above six chutes. A corrugated plate 204i is fixed to the bottom of the lifting frame 204d.

[0053] The setting of the corrugated plate 204i can prevent the water in the storage tank 101 from splashing out. The first bevel gear 204g and the second bevel gear 204h are meshed, so that the rotation of the adjusting column 204c can drive the rotating rod 203b to rotate, thereby driving the switch block 203c to rotate by the rotating rod 203b.

[0054] When the extrusion disc 201i moves downward, the end of the guide block 204e first slides from the first chute 204c-1 to the second chute 204c-2.

[0055] When the end of the guide block 204e slides downward in the first chute 204c-1, the guide block 204e does not drive the adjusting column 204c to rotate. At this time, the extrusion disc 201i extrudes the sludge filter cloth 106, so that the sludge in the sludge filter cloth 106 is separated from the muddy water.

[0056] When the end of the guiding block 204e slides from the first sliding groove 204c-1 into the second sliding groove 204c-2, the guiding block 204e starts to drive the adjusting column 204c to rotate. The adjusting column 204c can drive the switch block 203c to rotate. At this time, the sewage discharge pipe 104 can be opened, so that the sludge under the sludge filter cloth 106 is squeezed out from the sewage discharge pipe 104. At this time, the opening of the sewage discharge pipe 104 gradually increases, and with the squeezing of the sludge filter cloth 106 by the squeezing disc 201i, there will still be moisture separated from the sludge.

[0057] When the end of the guiding block 204e slides from the second sliding groove 204c-2 to the third sliding groove 204c-3, the opening of the sewage discharge pipe 104 is the largest at this time. At this time, the guiding block 204e slides downward in the third sliding groove 204c-3 to keep the opening of the sewage discharge pipe 104 the largest, so that the sludge under the sludge filter cloth 106 is stably squeezed out from the sewage discharge pipe 104.

[0058] When the end of the guiding block 204e slides from the third sliding groove 204c-3 to the fourth sliding groove 204c-4, the guiding block 204e can drive the adjusting column 204c to rotate in a reset manner, so that the switch block 203c starts to reset, thereby making the opening of the sewage discharge pipe 104 gradually decrease.

[0059] When the end of the guiding block 204e slides from the fourth sliding groove 204c-4 to the fifth sliding groove 204c-5, the sewage discharge pipe 104 has been closed, and the sludge is no longer discharged at this time. As the squeezing disc 201i moves downward, the moisture in the sludge filter cloth 106 is separated again.

[0060] During the process of the guiding block 204e moving downward in the fifth sliding 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, through the reset pulling force of the first spring 201c, the lifting platform 201a can move upward, thereby driving the squeezing disc 201i to move upward, so that the guiding block 204e slides from the fifth sliding groove 204c-5 into the sixth sliding groove 204c-6. As the squeezing disc 201i moves upward, the guiding block 204e slides from the sixth sliding groove 204c-6 into the first sliding groove 204c-1 again.

[0061] The groove depths of the fifth sliding groove 204c-5 and the sixth sliding groove 204c-6 are greater than the groove depth of the fourth sliding groove 204c-4, so that the guiding block 204e can only slide from the fifth sliding groove 204c-5 into the sixth sliding groove 204c-6.

[0062] The notch depth at the connection of the first sliding groove 204c-1 and the second sliding groove 204c-2 is greater than the notch depth of the sixth sliding groove 204c-6 on one side thereof, so that the guiding block 204e can only move from the first sliding groove 204c-1 into the second sliding groove 204c-2.

[0063] Specifically, the adjusting assembly 200 further includes a switch member 205 disposed on the adjusting member 204. The switch member 205 includes a lifting rod 205a that slides within the lifting frame 204d. A lifting ring 205b is fixed to the top of the lifting rod 205a, and a connecting rod 205c is fixed to the bottom of the lifting rod 205a.

[0064] The lifting rod 205a is used to support the lifting ring 205b, so that the lifting ring 205b can perform stable lifting movement. The connecting rod 205c is used to connect multiple lifting rods 205a, thereby improving the stability of the lifting rod 205a.

[0065] Specifically, a fixing rod 205d is fixed to the surface of the lifting ring 205b, and a rack 205e is fixed to the end of the fixing 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 meshes with the rack 205e, and a toothed plate 205h is fixed to the top of the adjusting ring 202c. The second adjusting gear 205g meshes with the toothed plate 205h.

[0066] By the upward movement of the lifting ring 205b, the fixing rod 205d can be driven to move upward, so that the fixing rod 205d drives the first adjusting gear 205f to rotate through the rack 205e, thereby causing the rotating shaft 201m to drive the butterfly valve 201n to rotate, and opening the butterfly valve 201n in this way, so that the silt in the conveying pipe 201h can enter the silt filter cloth 106.

[0067] While the rotating shaft 201m is rotating, the second adjusting gear 205g can be driven to rotate, so that the second adjusting gear 205g drives the toothed plate 205h to move, so that the toothed plate 205h drives the adjusting ring 202c to move, thereby causing the through groove 202c-1 on the adjusting ring 202c to communicate with the end of the water delivery pipe 202a, so that the water on the top of the pressing disc 201i enters the water delivery pipe 202a through the adjusting frame 202b, and then flushes out to the outer surface of the silt filter cloth 106 from the other end of the water delivery pipe 202a, thereby cleaning the silt filter cloth 106.

[0068] Specifically, a positioning post 205i is fixed to the bottom of the lifting ring 205b, and the other end of the positioning post 205i is fixed to the top of the connecting rod 205c. A positioning groove 205i-1 is formed on the surface of the positioning post 205i. The number of the positioning grooves 205i-1 is two, which are respectively arranged at both ends of the positioning post 205i. A clamping block 205j is clamped in the positioning groove 205i-1. A positioning block 205k is fixed to one side of the clamping block 205j, and a driving sleeve 205l is fixed to one side of the clamping block 205j. A third spring 205m is arranged in the driving sleeve 205l.

[0069] The third spring 205m is in a compressed state. The reset elastic force of the third spring 205m can drive the driving sleeve 205l to drive the clamping block 205j away from the positioning groove 205i-1, so as to release the limit on the positioning post 205i, enabling the positioning post 205i to slide in the lifting frame 204d, and the positioning block 205k slides on the surface of the adjusting post 204c.

[0070] Specifically, a lifting groove 204c-7 is formed on the surface of the adjusting post 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 to the surface of the lifting sleeve 205n. A placement groove 204c-8 is formed on the surface of the adjusting post 204c. The positioning block 205k can move into the placement groove 204c-8.

[0071] Lifting sleeves 205n, fourth springs 205o, driving blocks 205p and placement grooves 204c-8 with opposite directions are arranged on the upper and lower sides of the adjusting post 204c. The fourth spring 205o is in a compressed state.

[0072] 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.

[0073] 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.

[0074] At this time, the extrusion disc 201i will move upward under the pulling force of the first spring 201c, and the lifting frame 204d will simultaneously rise on the surface of the adjustment column 204c. When the lifting ring 205b moves to the bottom of the driving block 205p above the adjustment column 204c, it can push the driving block 205p, causing the driving block 205p to move upward, compressing the corresponding fourth spring 205o. When the positioning block 205k rises to one side of the placement groove 204c-8 above the adjustment column 204c, under the pushing force of the third spring 205m, the positioning block 205k can be moved into the placement groove 204c-8. At this time, the clamping block 205j moves away from the positioning groove 205i-1, thereby releasing the limit on the positioning column 205i. At this time, under the restoring elastic force of the fourth spring 205o, the driving block 205p can drive the lifting ring 205b to move downward, thereby causing the lifting ring 205b to drive the butterfly valve 201n to close, and causing the water delivery pipe 202a to be cut off by the adjustment ring 202c, stopping the cleaning of the sludge filter cloth 106. 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 one side of the clamping block 205j.

[0075] As the slurry inlet pipe 105 transports the muddy water into the storage tank 101, the lifting platform 201a drives the extrusion disc 201i to move downward. The extrusion disc 201i drives the positioning block 205k to move downward through the lifting frame 204d, causing the inclined surface below the placement groove 204c-8 to squeeze the positioning block 205k, thereby causing the clamping block 205j to move into the positioning groove 205i-1. At this time, the positioning block 205k can slide downward on the surface of the adjustment column 204c.

[0076] During use, the current illustrated state is the state where the lifting platform 201a moves downward. As the slurry inlet pipe 105 transports the muddy water into the storage tank 101, the load-bearing of the lifting platform 201a increases, thereby driving the extrusion disc 201i to move downward, squeezing the sludge in the sludge filter cloth 106, so that the water 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 tank 101. At this time, the end of the guide block 204e slides downward in the first chute 204c-1.

[0077] As the extrusion disc 201i moves downward, the end of the guide block 204e slides from the first chute 204c-1 into the second chute 204c-2, then from the second chute 204c-2 into the third chute 204c-3, then from the third chute 204c-3 into the fourth chute 204c-4, and then from the fourth chute 204c-4 into the fifth chute 204c-5. This process can filter out the water in the sludge and discharge the sludge from the sewage discharge pipe 104 until the sewage discharge pipe 104 is closed again.

[0078] When the guiding block 204e slides downward in the fifth sliding groove 204c-5, the lifting frame 204d drives the lifting ring 205b to move towards the driving block 205p below the adjusting column 204c, so that the lifting ring 205b compresses the fourth spring 205o by squeezing the driving block 205p. When the positioning block 205k moves to one side of the placement groove 204c-8 below the adjusting column 204c, under the thrust of the third spring 205m, the positioning block 205k can be moved into the placement groove 204c-8. At this time, the clamping block 205j moves away from the positioning groove 205i-1, thus releasing the limit on the positioning column 205i. At this time, under the restoring 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 silt in the conveying pipe 201h can enter the silt filter cloth 106. At the same time, the water on the top of the extrusion disc 201i can enter the water conveying pipe 202a through the adjusting frame 202b, and then be flushed from the other end of the water conveying pipe 202a to the outer surface of the silt filter cloth 106, so as to clean the silt filter cloth 106.

[0079] During the upward movement of the lifting ring 205b, since the positioning block 205k moves into the placement groove 204c-8, the lifting frame 204d cannot move relative to the adjusting column 204c, so as to position the extrusion disc 201i. As the lifting ring 205b rises, another positioning groove 205i-1 on the surface of the positioning column 205i will move to one side of the clamping block 205j. At this time, the extrusion disc 201i will move upward under the pulling force of the first spring 201c, and through the inclined surface extrusion of the placement groove 204c-8 below the adjusting column 204c, the positioning block 205k can be moved out of the placement groove 204c-8. At this time, the positioning block 205k can push the clamping block 205j to move into the positioning groove 205i-1, so as to position the positioning column 205i, so that there is no relative movement between the positioning column 205i and the lifting frame 204d, so as to fix the opened butterfly valve 201n and prevent the butterfly valve 201n from closing by itself.

[0080] At this time, as the extrusion disc 201i rises, silt continuously enters the silt filter cloth 106 from the conveying pipe 201h. During this process, the guiding block 204e slides from the fifth chute 204c-5 into the sixth chute 204c-6, and then slides from the sixth chute 204c-6 into the first chute 204c-1. As the guiding block 204e rises in the first chute 204c-1, the lifting ring 205b moves to the bottom of the driving block 205p above the adjusting column 204c and pushes the driving block 205p, causing the driving block 205p to move upward and compressing the corresponding fourth spring 205o. When the positioning block 205k rises to one side of the placement groove 204c-8 above the adjusting column 204c, under the thrust of the third spring 205m, the positioning block 205k can be made to move into the placement groove 204c-8. At this time, the clamping block 205j moves away from the positioning groove 205i-1, thereby releasing the limit on the positioning column 205i. At this time, under the restoring elastic force of the fourth spring 205o, the driving block 205p can drive the lifting ring 205b to move downward, thereby causing the lifting ring 205b to drive the butterfly valve 201n to close and the water delivery pipe 202a to be cut off by the adjusting ring 202c, stopping the cleaning of the silt filter cloth 106. 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 one side of the clamping block 205j.

[0081] As the slurry inlet pipe 105 conveys the muddy water into the storage tank 101, the lifting platform 201a drives the extrusion disc 201i to move downward. The extrusion disc 201i drives the positioning block 205k to move downward through the lifting frame 204d, causing the inclined surface below the placement groove 204c-8 to squeeze 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.

[0082] Through the above technical solution, the gravity of the silt can be utilized to apply pressure to the silt itself, thereby improving the separation efficiency of the silt, and the silt filter cloth 106 can be automatically cleaned to prevent the filter holes of the silt filter cloth 106 from being blocked.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
