Description

Technical Field

[0001] The invention relates to the technical field of silt clearing equipment, and in particular to a silt clearing device for water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals.

[0003] During the long-term operation of water conservancy projects, channels and other trenches, as key channels for water delivery, are prone to silt accumulation. The accumulation of silt not only hinders the smooth flow of water and reduces water delivery efficiency, but may also cause channel blockage, affecting the normal operation of the entire water conservancy system.

[0004] Existing dredging devices are generally large in size, and are seriously lacking in flexibility and convenience during actual operations. Faced with winding channels of varying widths, large-scale dredging equipment is often difficult to use, and it is even impossible to enter narrow areas for dredging operations, which undoubtedly brings great difficulties to the maintenance of water conservancy projects; and considering that most of the existing channels are curved, when the dredging device turns, due to the limitations of its internal mechanical structure and transmission system, the speed inside and outside the device is difficult to synchronize, and there is a significant difference. This speed difference will cause the internal structural parts of the device to bear uneven stress during the turning process of the device, accelerate the wear and damage of the components, and increase maintenance costs and downtime. At the same time, the friction between the outside of the device and the surface of the channel will also intensify, causing wear on the surface of the channel, reducing the service life and water delivery performance of the channel.

[0037] like Figures 1 to 13 As shown, a sludge cleaning device for water conservancy projects provided by an embodiment of the present invention is used to clean sludge in a channel, including a main body, a driving mechanism and a suction mechanism. The length extension direction of the channel is assumed to be a first direction, and the main body is slidably arranged in the channel along the first direction to gather the sludge in the channel; the driving mechanism includes a bottom plate 105 and two power assemblies, the bottom plate 105 is arranged on the main body, the two power assemblies are arranged along a second direction, and the two power assemblies are symmetrically arranged, the second direction is the width extension direction of the channel, and the first direction is perpendicular to the second direction; each power assembly includes a rotating rod 113 and a speed regulating part, and two rotating rods 113 are provided, one end of the two rotating rods 113 is respectively rotatably arranged on the bottom plate 105, the rotation centers of the two rotating rods 113 coincide, and a speed regulating part is arranged between the two rotating rods 113. There is an angle, the rotation axis of the rotating rod 113 extends along the third direction, and the third direction is perpendicular to the first direction and the second direction respectively; an elastic member 114 is provided between each rotating rod 113 and the bottom plate 105, and the elastic member 114 is a spring sheet with elastic force, and the elastic member 114 enables the two rotating rods 113 to approach each other, and the other ends of the two rotating rods 113 are provided with driving wheels 116, and the two driving wheels 116 are respectively connected to the same side wall of the channel in a rolling manner; the speed regulating part is used to drive the driving wheel 116 to roll on the side wall of the channel and control the rotation speed of the driving wheel 116 according to the distance between the rotation axis of the rotating rod 113 and the side wall of the channel in the second direction; the distance between the rotation axis of the rotating rod 113 and the side wall of the channel where the driving wheel 116 is located in the second direction is positively correlated with the rotation speed of the driving wheel 116;

[0038] The suction mechanism is used to extract the sludge gathered in the main body.

[0039] The main body is set in the channel, and the driving wheel 116 is in contact with the side wall of the channel. The forward path of the sludge cleaning device for water conservancy projects is determined by the side wall of the channel, which reduces the impact of environmental factors around the channel on it and greatly expands the scope of application of dredging operations; two power components are set, each power component corresponds to a side wall of the channel, and the two rotating rods 113 in each power component are matched with each other. The two rotating rods 113 in each power component have the same angle under the action of their respective corresponding elastic members 114, so that the main body in the channel is relatively stable in the second direction. At the same time, the sludge cleaning device for water conservancy projects is also suitable for channels of various specifications.

[0040] When the main body enters the curved part from the straight part of the channel, the shortest distance between the rotation axis of the rotating rod 113 in the power assembly near the outside of the curve and the outer wall of the curve is greater than the shortest distance between the rotation axis of the rotating rod 113 in the power assembly near the inside of the curve and the inner wall of the curve. At this time, the rolling speed of the driving wheel 116 in the power assembly near the outside of the curve in the channel is greater than the rolling speed of the driving wheel 116 in the power assembly near the inside of the curve in the channel, so that the rotation angles of the main body on the inner and outer sides of the curved part are consistent, thereby reducing the degree of wear of the structural components in the sludge cleaning device for water conservancy projects in the curved part of the channel.

[0041] In this embodiment, each speed regulating part includes a friction disc 117, a rotating drum 118, a driving wheel 119, a guide rod 120 and a transmission member. The friction disc 117 is rotatably arranged on the base plate 105, and the rotation axis of the friction disc 117 extends along the third direction. The two rotating rods 113 in the same power assembly are coaxial with the friction disc 117; each power assembly also includes a motor 115, which is fixedly mounted on the base plate 105, and the axis of the output shaft of the motor 115 extends along the second direction and intersects with the rotation axis of the friction disc 117. The rotating drum 118 rotates synchronously with the output shaft of the motor 115 and can slide relative to the output shaft of the motor 115. The rotating drum 118 is sleeved on the output shaft of the motor 115, and the axis of the rotating drum 118 A through groove 121 penetrating the rotating drum 118 is provided on the circumference, and a key block 122 is provided on the output shaft of the motor 115, and the key block 122 is slidably set in the through groove 121; a driving wheel 119 is sleeved on the rotating drum 118, and the driving wheel 119 is fixedly connected to the rotating drum 118, and a first spring 123 is provided at one end of the rotating drum 118 close to the motor 115, and the first spring 123 is sleeved on the output shaft of the motor 115, and the end of the first spring 123 away from the rotating drum 118 is fixedly connected to the output shaft of the motor 115, and the circumference of the driving wheel 119 contacts the end surface of the friction disk 117; one end of the guide rod 120 is rotatably connected to the end of the rotating drum 118 away from the motor 115, and the other end of the guide rod 120 is slidably connected to the side wall of the channel.

[0042] After the body is placed in the channel, the guide rod 120 abuts against the side wall of the channel under the action of the first spring 123, and the first spring 123 is in a compressed state. For channels of different widths, the compression amount of the first spring 123 by the guide rod 120 is inconsistent, the distance between the axis of the driving wheel 119 and the friction wheel is inconsistent, and the speed at which the friction disc 117 is driven to rotate by the driving wheel 119 after the motor 115 rotates is inconsistent. The transmission member transmits the rotation of the friction wheel to the driving wheel 116.

[0043] In this embodiment, two transmission members are provided, each transmission member includes a sleeve 130, a gear 131 and a driven wheel 132. The sleeve 130 is sleeved on a rotating rod 113, and the sleeve 130 is rotatably connected to the rotating rod 113. One end of the sleeve 130 close to the driving wheel 116 is provided with teeth. The gear 131 is rotatably provided on a driving wheel 116, and the gear 131 is meshed with the sleeve 130. The driven wheel 132 is sleeved on the sleeve 130, and the driven wheel 132 is meshed with the sleeve 130. The driven wheel 132 can rotate synchronously with the sleeve 130. A boss 133 is provided on the circumference of the sleeve 130. The boss 133 is located at one end of the driven wheel 132 away from the rotation axis of the driven wheel 132. A sliding rod 134 extending along the axial direction of the sleeve 130 is provided at one end of the driven wheel 132 close to the boss 133. The sliding rod 134 penetrates the boss 133 and is slidably connected with the boss 133. The circumference of the driven wheel 132 contacts the end surface of the friction disk 117. The rotation of the friction disk 117 can drive the driving wheel 116 to rotate through the sleeve 130 and the gear 131.

[0044] In this embodiment, the driven wheel 132 is slidably connected to the sleeve 130 along the axial direction of the sleeve 130, a second spring 135 is sleeved on the sleeve 130, one end of the second spring 135 is fixedly connected to the sleeve 130, and the other end of the second spring 135 is connected to the driven wheel 132, a swivel 136 is sleeved on the rotating rod 113, the swivel 136 is slidably connected to the rotating rod 113 along the axial direction of the rotating rod 113, and the swivel 136 is rotatably connected to the driven wheel 132; the two side surfaces of the bottom plate 105 close to the channel side wall are both arc surfaces, the axis of the arc surface extends along the third direction, and the vertical line between the axis of the arc surface and the rotation axis of the rotating rod 113 extends along the second direction, and the centers of the two arc surfaces are located between the rotation axes of the two friction disks 117 in the two power assemblies, and the swivel 136 is slidably connected to the corresponding arc surfaces.

[0045] After the channel becomes wider, in order to enable the corresponding driving wheels 116 to abut against the side wall of the channel, the two rotating rods 113 in the same power assembly approach each other under the action of their corresponding elastic members 114, and the driven wheel 132 pushes the rotating ring 136 to always abut against the curved surface of the bottom plate 105 under the action of the second spring 135. Under the guidance of the curved surface on the bottom plate 105, the driven wheel 132 will approach the rotation axis of the rotating rod 113, that is, the driven wheel 132 approaches the center of the friction disk 117. When the rotation speed of the friction disk 117 remains unchanged, the transmission ratio between the friction disk 117 and the driven wheel 132 is reduced, so that the rotation speed of the driven wheel 132 is reduced, and the rotation speed of the driving wheel 116 is also reduced, and the movement speed of the sludge cleaning device for water conservancy projects in the channel is slowed down. As the channel side becomes wider and the amount of silt inside increases, the speed of the silt cleaning device for water conservancy projects is slowed down, which allows the suction mechanism to better extract the silt gathered in the channel. At the same time, it also increases the driving force for the silt cleaning device for water conservancy projects to move forward, and the silt cleaning device for water conservancy projects moves more stably in the channel.

[0046] In this embodiment, a first guide wheel 137 is rotatably mounted on one end of the guide rod 120 that is slidably connected to the channel side wall, and the rotation axis of the first guide wheel 137 extends along the third direction; a second guide wheel 138 is rotatably mounted on each swivel 136, and the rotation axis of the second guide wheel 138 extends along the third direction, and the second guide wheel 138 is rollingly connected to the arc surface on the bottom plate 105. When the sludge cleaning device for water conservancy projects moves forward in the channel, the first guide wheel 137 can reduce the friction between the guide rod 120 and the side wall of the channel; when the rotating rod 113 rotates relative to the bottom plate 105, the second guide wheel 138 can reduce the friction between the swivel 136 and the bottom plate 105.

[0047] In this embodiment, the driving mechanism also includes a shell 110, which is arranged on the body, and the bottom plate 105 is arranged in the shell 110, the guide rod 120 passes through the shell 110 and is slidably connected to the shell 110, and the shell 110 is provided with through holes 124 with the same number as the rotating rod 113, and each rotating rod 113 is rotatably arranged in a through hole 124; a protective cover 111 is provided on the end of the rotating rod 113 close to the driving wheel 116, and the protective cover 111 is arranged outside the rotating drum 118 and the gear 131, and the driving wheel 116 passes through the protective cover 111 and is rotatably connected to the protective cover 111, and a rubber sleeve 112 is provided on the through hole 124, and the rubber sleeve 112 is connected to the protective cover 111, and the rubber sleeve 112 and the protective cover 111 can prevent the silt in the channel from contacting with the structural components in the shell 110 and used for transmission, thereby improving the safety and reliability of the silt cleaning device for water conservancy projects during use.

[0048] In this embodiment, the main body includes a push plate 100 and two side plates 101. The push plate 100 is slidably arranged on the bottom surface of the channel along a first direction. One side of the two side plates 101 is rotatably arranged on the push plate 100 respectively, and the other side of the two side plates 101 is slidably connected to the side wall of the channel. The rotation axis of the two side plates 101 extends along a third direction. In the forward direction of the push plate 100, the push plate 100 and the two side plates 101 gather the silt in the channel, and the driving mechanism is located behind the two side plates 101, which can effectively reduce the influence of the silt on the driving mechanism.

[0049] In this embodiment, elastic bands 102 are respectively provided on the surfaces of the two side panels 101 that are away from each other, and the two ends of each elastic band 102 are respectively connected to the push plate 100 and the corresponding side panel 101. Under the action of the corresponding elastic bands 102, the two side panels 101 rotate around their respective rotation axes and move away from each other. At the same time, the two side panels 101 can always be in contact with the side walls of the corresponding channels to adapt to channels of different widths.

[0050] In this embodiment, the suction mechanism includes a sludge pipe 103 and a sludge pump 104. One end of the sludge pipe 103 is fixedly mounted on the push plate 100, and the sludge pipe 103 is located at the front side in the forward direction of the push plate 100. The sludge pump 104 is fixedly mounted on the push plate 100 and is used to draw away the sludge on the front side of the push plate 100 through the sludge pipe 103. One end of the sludge pipe 103 away from the sludge pump 104 is close to the bottom of the channel and a distance is provided between the end of the sludge pipe 103 and the bottom of the channel to ensure that the sludge can enter the sludge pipe 103 from the end of the sludge pipe 103.

[0051] In this embodiment, two driving mechanisms are provided, the two driving mechanisms are arranged along the third direction, and the driving wheel 116 in each driving mechanism is rollingly connected to the side wall of the channel. The two driving mechanisms can ensure that the push plate 100 is more stable when moving forward in the channel.

[0052] The working principle of the sludge cleaning device for water conservancy projects provided in the above embodiment is:

[0053] First, the guide rod 120 is pushed, and the guide rod 120 drives the drum 118 to slide on the output shaft of the motor 115. The drum 118 compresses the first spring 123 by cooperating with the output shaft of the motor 115, and then all the rotating rods 113 are rotated to increase the angle between the two rotating rods 113 in the same power assembly. At the same time, the two side plates 101 are rotated to make the two side plates 101 close to the sludge pipe 103, thereby reducing the overall length of the sludge cleaning device for water conservancy projects in the second direction, and then the water conservancy project is The sludge cleaning device for water conservancy project is placed in the channel, and the sludge pipe 103 is located in front of the push plate 100. Then the external force applied to the sludge cleaning device for water conservancy project is removed, and the guide rod 120 slides on the shell 110 along the second direction to drive the first guide wheel 137 to contact the side wall of the channel. The rotating rod 113 rotates around its own rotation axis under the action of the elastic member 114 so that the driving wheel 116 contacts the side wall of the channel, and the side plate 101 rotates under the action of the corresponding elastic band 102 and contacts the side wall of the channel.

[0054] Then start the motor 115 and the sludge pump 104. The motor 115 drives the rotating drum 118 to rotate through the cooperation between the key block 122 and the through groove 121 on the rotating drum 118. The rotating drum 118 drives the driving wheel 119 to rotate relative to the guide rod 120. The driving wheel 119 rotates and drives the friction disk 117 to rotate around its own axis through the contact with the friction disk 117. The rotation of the friction disk 117 drives the driven wheel 132 to rotate. The driven wheel 132 drives the sleeve 130 to rotate through the slide rod 134. The sleeve 130 drives the driving wheel 116 to rotate through the gear 131. The driving wheel 116 rolls on the side wall of the channel and drives the sludge cleaning device for water conservancy projects to move forward in the channel. The push plate 100 and the two side plates 101 gather the sludge in the channel to the vicinity of the sludge pipe 103, and the sludge pump 104 extracts the sludge in the channel through the sludge pipe 103.

[0055] When the sludge cleaning device for water conservancy projects is in the straight section of the channel, the contact position between the first guide wheel 137 in each power component and the side wall of the channel is located at the midpoint of the line between the two driving wheels 116 in the same power component and the side wall of the channel, the distances between the two driving wheels 119 in the two power components and the rotation axes of the corresponding friction disks 117 are consistent, the rotation speeds of the two friction disks 117 are consistent, and the push plate 100 can move forward in the first direction in the channel. When the sludge cleaning device for water conservancy projects is in the curved part of the channel, due to the effect of the curved side wall of the channel, the length of the guide rod 120 in the power assembly in contact with the outer wall of the channel extending out of the outer shell 110 is greater than the length of the guide rod 120 in the power assembly in contact with the inner wall of the channel extending out of the outer shell 110, and the first spring 123 in the power assembly located on the outside pushes the rotating drum 118 to slide on the output shaft of the motor 115 in the direction away from the motor 115, and the rotating drum 118 drives the driving wheel 119 to approach the rotation axis of the friction disk 117, and the rotation speed of the friction disk 117 increases. Relatively speaking, the speed at which the friction disk 117 drives the driving wheel 116 to rotate through the driven wheel 132 increases, and the moving speed of the sludge cleaning device for water conservancy projects on the outer wall of the channel increases.

[0056] The first spring 123 in the power assembly located on the inner side is compressed under the action of the guide rod 120 and the rotating drum 118, and the rotating drum 118 drives the corresponding driving wheel 119 to move in the direction away from the rotation axis of the friction disk 117, and the rotation speed of the friction disk 117 is reduced. Relatively speaking, the friction disk 117 drives the driving wheel 116 to rotate at a reduced speed through the driven wheel 132, and the movement speed of the sludge cleaning device for water conservancy projects on the outer wall of the channel is reduced. The first spring 123 in the power assembly located on the outer side pushes the rotating drum 118 to rotate on the motor. The output shaft of the hydraulic project 115 slides in the direction away from the motor 115, the rotating drum 118 drives the driving wheel 119 to approach the rotation axis of the friction disk 117, and the rotation speed of the friction disk 117 increases. Relatively speaking, the rotation speed of the driving wheel 116 driven by the friction disk 117 through the driven wheel 132 increases. The overall moving direction of the sludge cleaning device for water conservancy projects in the channel is still along the first direction, and there is no excessive wear on the internal components of the driving mechanism, and there is no significant wear between the sludge cleaning device for water conservancy projects and the channel.
