Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic lying dams, in particular to a bottom-opening hydraulic lying dam. Background Art

[0002] Hydraulic lying dam gates are used in various large-scale water supply and drainage, water conservancy and hydropower, and municipal projects. The electrical control cabinet sends a signal to the hydraulic pump station, and the hydraulic pump station provides the corresponding power source to act on the split hydraulic hoist on the steel gate to realize the opening and closing of the steel gate. When the hydraulic lying dam gate is needed, the opening of the gate can be well controlled, so that the opening and closing of the channel can be achieved.

[0003] A Chinese patent with the public number CN218813559U discloses a hydraulic lying dam system, which is provided with a dam and a control component. The control component is used to control the operation of the dam. The control component is a hydraulic cylinder, and a hydraulic rod is provided on the hydraulic cylinder. The hydraulic rod and the dam are connected by bolts, and the dam can be relied on to open and close the waterway, so that the opening of the waterway can be well controlled. When the dam is poured into the water, impurities will enter the inside of the dam, so an impurity isolation net is provided on the dam. The impurity isolation net can be used to isolate impurities well, thereby preventing large impurities from entering the inside of the dam.

[0004] However, when the above scheme uses a hydraulic lying dam, there are often floating objects in the river channel. If a large number of floating objects are washed to the gate position of the hydraulic lying dam, the gate may be blocked, causing the gate to be unable to open or close normally. This will affect the normal operation of the hydraulic lying dam and the control of water flow. In addition, the gate of the hydraulic lying dam is placed horizontally. The water flowing through the top of the dam is likely to cause sand and gravel to accumulate on the riverbed, affecting the smooth flow of water and increasing maintenance costs. It is not suitable for waters with large water flow and deep water sources. Therefore, a bottom-opening hydraulic lying dam is proposed to solve the above problems. Utility Model Content

[0005] Based on the technical problems that a large amount of floating objects in the existing lying dam rush to the gate position of the hydraulic lying dam, which will block the gate and affect the normal operation of the hydraulic lying dam, and the gate of the hydraulic lying dam is placed horizontally, which is easy to cause sand and gravel accumulation, affecting the smooth flow of water and increasing maintenance costs, the utility model proposes a bottom-opening hydraulic lying dam.

[0006] The utility model provides a bottom-opening hydraulic lying dam, which comprises a base and a dam body. A filtering device is arranged inside the base, and the filtering device comprises a filtering net. The deflection of the filtering net intercepts floating objects in the water area.

[0007] A hydraulic device is arranged inside the base, and the hydraulic device comprises a control hydraulic cylinder. The telescopic rod of the control hydraulic cylinder is telescoped to control the tilting angle of the dam body.

[0008] Preferably, the filtering device further comprises a fixed hydraulic cylinder, which is fixedly mounted inside the base, and a connecting block is fixedly mounted on one end of a telescopic rod of the fixed hydraulic cylinder.

[0009] Through the above technical scheme, the telescopic rod of the fixed hydraulic cylinder is extended and retracted to drive the connecting block fixedly installed therewith to rise and fall, and drive the rotating ring rotatably connected to the connecting block through the connecting rod to rotate, thereby driving the support rod fixedly installed with the rotating block and slidably plugged with the fixed block to deflect, so as to fix the rotating rod.

[0010] Preferably, a support seat is fixedly installed inside the base, and rotating rings are rotatably connected to both sides of the support seat, and the outer surface of the rotating ring is hinged to the inside of the connecting block through a pin shaft.

[0011] Through the above technical solution, the rotating ring is connected by rotating on the support seat, which fixes it without affecting its rotation. The rotating ring and the connecting block are hinged by a pin shaft. The lifting and lowering of the connecting block drives the rotating ring to rotate, thereby driving the support rod fixedly installed with the rotating block and slidably plugged with the fixed block to deflect, so as to fix the rotating rod.

[0012] Preferably, a rotating block is fixedly installed on the outer surface of the rotating ring, a fixed block is fixedly installed on the outer surface of the supporting seat, a support rod is slidably inserted on the outer surface of the rotating block, and one end of the support rod is hinged to the outer surface of the fixed block through a spherical hinge.

[0013] Through the above technical scheme, the rotating block is fixedly installed, and one end of the support rod is slidably inserted into it, which supports it without affecting its deflection. The rotation of the rotating ring drives the support rod slidably inserted into the rotating block to rotate. One end of the support rod is hinged to the outer surface of the fixed block through a spherical hinge, which supports the support rod without affecting its clamping movement driven by the rotating rod, thereby fixing the rotating rod.

[0014] Preferably, a rotating rod is fixedly installed inside the base via a bearing, the outer surface of the rotating rod is fixedly installed with one end of the filter screen, and a trash bin is provided on the outer surface of the base, and the trash bin is located on one side of the dam body.

[0015] Through the above technical solution, the rotating rod is fixedly installed by the bearing. When the rotating rod is fixed, its rotation does not affect the base. The supporting rod passes through the inside of the supporting seat so that the supporting rod on the supporting seat can clamp and fix it. The rotating rod and the filter net are fixedly installed to drive the filter net to rotate so as to filter and collect floating objects in the water area. After the filter net rotates, the intercepted floating objects are placed in a trash can for cleaning.

[0016] Preferably, the hydraulic device also includes a rotating rod, both ends of which are fixedly mounted to the outer surface of the base via bearings, the inner wall of the rotating rod is rotatably sleeved with the outer surface of the rotating rod, the outer surface of the rotating rod is fixedly mounted to the outer surface of the dam body, electromagnets are fixedly mounted on both sides of the rotating rod, and the outer surface of the electromagnet is magnetically connected to the outer surface of the rotating rod via an adsorption piece.

[0017] Through the above technical scheme, the rotating rod and the base are fixedly installed through bearings to support them without affecting the base. The rotating rod and the rotating rod are rotatably sleeved, so that the rotation of the rotating rod does not affect the rotating rod. By fixing the electromagnets on both sides of the rotating rod and magnetically connecting them to the rotating rod through adsorption parts, the electromagnets are energized, and the rotating rod drives the rotating rod to rotate, thereby driving the filter to rotate, so that the floating objects intercepted by it can be put into the trash bin for cleaning.

[0018] Preferably, a rotating seat is fixedly mounted on the outer surface of the base, the outer surface of the rotating seat is rotatably connected to the outer surface of the control hydraulic cylinder, and one end of the telescopic rod of the control hydraulic cylinder is hinged to the outer surface of the dam body through a pin.

[0019] Through the above technical scheme, the rotating seat is rotatably connected to the control hydraulic cylinder, which fixes it and facilitates its rotation. One end of the telescopic rod of the control hydraulic cylinder is hinged to the dam body through a pin shaft, so that the tilting of the dam body can be controlled by telescoping the telescopic rod of the hydraulic cylinder.

[0020] The beneficial effects of the present invention are:

[0021] 1. By setting up a filtering device, floating objects in the water area are intercepted. The telescopic rod of the fixed hydraulic cylinder is extended and retracted to drive the connecting block to rise and fall, so that the rotating ring rotates. The rotating block is fixedly installed on the rotating ring, and one end of the support rod is fixedly installed with it. The rotation of the rotating ring drives the support rod to rotate. The other end of the support rod is hinged with the fixed pin, which does not affect its clamping movement driven by the rotating rod. After the rotating rod is rotated and connected, it passes through the inside of the support seat so that the support rod on the support seat clamps and fixes it. The rotating rod is fixedly installed with the filter net, which drives the filter net to rotate so that the floating objects in the water area are filtered and collected and then enter the garbage bin. This solves the problem that there are often floating objects in the river when using the hydraulic lying dam. If a large amount of floating objects are washed to the gate position of the hydraulic lying dam, it may block the gate, causing the gate to be unable to open or close normally. This will affect the normal operation of the hydraulic lying dam and the technical problem of water flow control.

When the electromagnet is energized, the rotating rod drives the rotating rod to rotate, thereby driving the filter to rotate, and the rotating seat is rotatably connected to the control hydraulic cylinder, which is convenient for it to rotate while fixing it. One end of the telescopic rod of the control hydraulic cylinder is fixedly installed with the dam body so that the tilting of the dam body can be controlled by telescoping the telescopic rod of the hydraulic cylinder. This solves the problem that when using a hydraulic lying dam, the gate of the hydraulic lying dam is placed horizontally, and water flowing through the dam top is likely to cause sand and gravel accumulation on the riverbed, affecting the smooth flow of water, increasing maintenance costs, and is not suitable for waters with large water flow and deep water sources.

If a large amount of floating objects are washed to the gate position of the hydraulic lying dam, it may block the gate, resulting in the gate being unable to open or close normally. This will affect the normal operation of the hydraulic lying dam and the technical problem of water flow control.

[0035] In order to control the tilting angle of the dam body 11 , a hydraulic device is provided inside the base 1 . The hydraulic device includes a control hydraulic cylinder 71 .

[0036] In order to drive the rotating rod 5 to rotate, the hydraulic device also includes a rotating rod 6, both ends of the rotating rod 6 are fixedly installed with the outer surface of the base 1 through bearings, the inner wall of the rotating rod 6 is rotatably connected with the outer surface of the rotating rod 5, the outer surface of the rotating rod 6 is fixedly installed with the outer surface of the dam body 11, and electromagnets 61 are fixedly installed on both sides of the rotating rod 6. The outer surface of the electromagnet 61 is magnetically connected to the outer surface of the rotating rod 5 through an adsorption piece. The rotating rod 6 is fixedly installed with the base 1 through bearings to support it without affecting the base 1. The rotating rod 6 is rotatably connected with the rotating rod 5, and the rotation of the rotating rod 6 does not affect the rotating rod 5. By fixing the electromagnet 61 on both sides of the rotating rod 6 and magnetically connecting with the rotating rod 5 through an adsorption piece, the electromagnet 61 is energized, and the rotating rod 6 drives the rotating rod 5 to rotate, thereby driving the filter screen 51 to rotate, so that the floating objects intercepted by it can be carried into the garbage bin 52 for cleaning.

[0037] In order to drive the dam body 11 to tip over, a rotating seat 7 is fixedly installed on the outer surface of the base 1. The outer surface of the rotating seat 7 is rotatably connected to the outer surface of the control hydraulic cylinder 71.

This solves the problem that when using a hydraulic lying dam, the gate of the hydraulic lying dam is placed horizontally, and water flowing through the dam top is likely to cause sand and gravel accumulation on the riverbed, affecting the smooth flow of water, increasing maintenance costs, and is not suitable for waters with large water flow and deep water sources.

[0039] Working principle: When it is necessary to adjust the water flow in the river, the control hydraulic cylinder 71 on the rotating seat 7 on the base 1 is started, and the retraction of the control hydraulic cylinder 71 pulls the dam body 11 upward to deflect, so that the water flow on one side of the filter screen 51 passes through the filter screen 51 and enters the other side of the dam body 11. After the water flow adjustment is completed, the dam body 11 can be reset by pushing the control hydraulic cylinder 71;

[0040] When it is necessary to process the garbage on one side of the filter screen 51, while adjusting the water flow, start the fixed hydraulic cylinder 2, and the fixed hydraulic cylinder 2 pulls the connecting block 21 to rise and fall. After the connecting block 21 drives the rotating ring 31 to rotate on the support seat 3, it drives the rotating block 4 to rotate, thereby driving multiple groups of support rods 42 to deflect on the fixed block 41, and then pulls one end of the support rod 42 to extend and retract on the rotating block 4, releasing the restriction on the rotating rod 5. At the same time, after the electromagnet 61 is energized, the rotating rod 5 and the rotating rod 6 are fixed, and the hydraulic cylinder 71 is controlled to pull the dam body 11 while driving the filter screen 51 to deflect synchronously. The garbage blocked by the filter screen 51 can enter the garbage bin 52 placed on one side of the dam body 11 for collection. By pulling up the garbage bin 52, the garbage can be processed, so that the garbage can be directly collected when the water level is adjusted.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
