Description

Technical Field

[0001] The invention relates to the technical field of culvert protection, and in particular to a control gate with a dredging structure for water conservancy projects. Background Art

[0002] A regulating gate is a hydraulic structure used to regulate the water level in a river or channel and control the flow of water. It has the function of regulating the upstream water level and the downstream discharge volume. Dredging is an important maintenance task to maintain the normal operation of the regulating gate. When a road passes through a water section, it is often necessary to set up a culvert below the road surface. In order to reduce the impact of water flow on the embankment scouring on both sides of the culvert, and at the same time meet different drainage needs and prevent possible floods, it is necessary to install regulating gates to control the water flow at the entrance and exit of the culvert, so that the culvert can meet the drainage needs and have sufficient stability and durability.

[0003] The patent specification with publication number CN215844419U discloses a regulating gate with a gate scouring and silting structure for water conservancy projects, including a gate, guide rods are symmetrically fixedly connected to the front and rear sides of the gate, sliders are slidably connected to the surface of the guide rods, a trapezoidal shovel plate is fixedly connected between the two sliders, and the surface of the trapezoidal shovel plate overlaps the side wall of the gate.

[0004] When the regulating gate is in use, the silt on the side wall of the gate is cleaned by using a shovel plate. The disadvantage is that the gate only cleans the surface of the gate. However, in actual use, the gate is installed on one side of the end wall. The silt does not directly affect the use of the gate body. Instead, in the process of periodically opening and closing the gate, the gate located on the inner side of the water flow will accumulate some sludge due to the sudden opening and closing of the water flow. That is, silt removal is mainly used to clean the silt on the inner side of the gate close to the water.

[0009] As a further solution of the present invention: the silt cleaning plate is installed between the two notches, and the notches are used to adjust the installation level of the silt cleaning plate.

[0010] As a further solution of the present invention: the push-pull mechanism includes a vertical plate fixedly connected to the silt cleaning plate, guide rods are slidably connected on both sides of the vertical plate, and a push-pull cylinder is installed on one side, the push-pull cylinder is electrically connected to the electrical control box, a push plate is fixedly connected between one ends of the two guide rods, and the push plate is fixedly connected to the telescopic rod of the push-pull cylinder.

[0015] Beneficial effects of the present invention: 1. In the present invention, an electric control box is installed at the top of the end wall, and two slots are opened at the two support frames of the limit gate on one side of the end wall. A push-pull mechanism is installed between the two slots with the help of a dredging plate, and a dredging mechanism is connected to one side of the push-pull mechanism.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 7 As shown, a regulating gate with a dredging structure for a water conservancy project comprises an end wall 1, a culvert 2 is installed at the bottom of one side of the end wall 1, a gate frame 3 is installed on the side of the end wall 1 away from the culvert 2, support frames 4 are fixedly connected to the adjacent two sides of the gate frame 3, a gate 5 is installed between the two support frames 4 and the top of the gate frame 3, a dredging plate 6 is detachably connected between the two support frames 4, a push-pull mechanism is installed on one side of the dredging plate 6, a dredging mechanism is installed on one side of the push-pull mechanism, an electric control box 7 is arranged on one side of the top of the gate frame 3, the push-pull mechanism and the dredging mechanism are both electrically connected to the electric control box 7, the dredging mechanism comprises a displacement component 8 connected to the push-pull mechanism, the displacement component 8 is connected to a cleaning component 9 on the side away from the push-pull mechanism, and the outer peripheral sides of the displacement component 8 and the cleaning component 9 are both adapted to fit the inner wall of the culvert 2; It should be noted that the top of the gate frame 3 exceeds the upper surface of the end wall 1, and a water gate 10 is opened in the middle of the bottom of the end wall 1. The gate 10 is a water gate adapted for the culvert 2. The culvert 2 is installed in the gate 10, and the water flow is regulated by opening and closing the gate 10 through the gate 5. The end wall 1 on the side where the culvert 2 is located will be buried in the roadbed when in use, and the gate 5 is located on the other side of the culvert 2. A ramp will be laid on the outside of the road on this side. The end wall 1 is used for water diversion, and the ramp is used to stabilize the soil layers on both sides of the water diversion road.

[0022] like Figures 1 to 3 As shown, the gate frame 3 includes columns 31 arranged on both sides, the tops of the two columns 31 are fixedly connected to the top frames 32, the tops of the two top frames 32 are fixedly connected to the cross frame 33, the two support frames 4 are fixedly installed on one side of the two adjacent columns 31, and the gate 5 includes a rotating handle 51 fixedly connected to the top of the cross frame 33, the middle part of the rotating handle 51 is rotatably connected to the screw rod 52, the screw rod 52 penetrates the cross frame 33 and extends between the two support frames 4, a rotating seat 53 is fixedly connected between the tops of the two support frames 4, the screw rod 52 is rotatably connected to the rotating seat 53, the bottom end of the screw 52 is rotatably connected to the gate plate 54, the inner sides of the two support frames 4 are evenly rotatably connected to multiple guide wheels 55 in the vertical direction, and one side of the gate plate 54 is rollingly connected to each guide wheel 55; It should be noted that the end wall 1 and the gate frame 3 are cast in cement as a whole, and the support frame 4 installed on one side of the end wall 1 is made of steel, which is used for structural support for the opening and closing of the gate 5. A base plate and a pedestal are installed on the top of the gate 5, and the rotating handle 51 passes through the cross frame 33 with the help of the base plate and the pedestal. The top of the screw 52 extends upward through the rotating handle 51 to adapt to the staff standing on the top plane of the column 31 to open and close the bottom gate 10. It has sufficient length. Specifically, the staff rotates the rotating handle 51 and the screw 52 moves vertically. During the movement, the guide wheels 55 installed on both sides of the support frame 4 limit the gate plate 54. At the same time, the inner side of the gate plate 54 is in contact with the end wall 1 at the gate 10 to realize the opening and closing control of the gate 10.

[0023] The support frame 4 is provided with a slot 11 on the outside of the gate 10 at the same horizontal plane, and the dredging plate 6 is installed between the two slots 11. The two slots 11 are used to adjust the installation height of the dredging plate 6. Since the dredging plate 6 is used to install the push-pull mechanism, and the pushing mechanism is directly connected to the dredging mechanism, the height of the dredging plate 6 is adjusted to make the initial push-pull position of the push-pull mechanism accurate, so as to facilitate the subsequent accurate lateral reciprocating displacement of the cleaning component 9 in the culvert 2 in the dredging mechanism.

[0024] like Figure 4 As shown, the push-pull mechanism includes a vertical plate 12 fixedly connected to the silt-clearing plate 6, and the vertical plate 12 is slidably connected to the guide rods 13 at both ends of the side away from the end wall 1, and a push-pull cylinder 14 is installed on one side of the vertical plate 12, and the push-pull cylinder 14 is electrically connected to the electric control box 7. A push plate 15 is fixedly connected between one end of the two guide rods 13, and the push plate 15 is fixedly connected to the telescopic rod of the push-pull cylinder 14. A shockproof plate 16 is installed on the side of the push plate 15 away from the push-pull cylinder 14, and the silt-clearing mechanism is fixedly connected to the shockproof plate 16; It should be noted that the telescopic action of the telescopic rod of the push-pull cylinder 14 is controlled by the electric control box 7 (see Figure 2 ), that is, the staff can control the telescopic action of the push-pull mechanism under the waterway above the road surface, and the guide rods 13 on both sides of the push-pull cylinder 14 limit the movement during reciprocating action; in addition, the dredging mechanism is not directly connected to the push plate 15 controlled by the push-pull cylinder 14, but a shockproof plate 16 for buffering the reciprocating action inertia of the dredging mechanism is provided between the push plate 15 and the dredging mechanism, so as to ensure the stability of the dredging mechanism when adjusting the dredging position and improve the service life of the device; Specifically, both ends of the outer side of the push plate 15 are fixedly connected to straight rods, and the straight rods serve as guides. Shock-proof springs are adapted and fixedly connected to the outer sides of the straight rods on both sides of the push plate 15. Shock-proof plates 16 are fixedly connected between the two shock-proof springs. The straight rods pass through the shock-proof plates 16 at the same time. When the action of the push-pull mechanism to move the dredging mechanism stops, the shock-proof springs rely on deformation to buffer the inertia of the dredging mechanism. The purpose is that when the dredging mechanism rotates and dredges on the same vertical plane of the culvert 2, only the inner wall of the culvert 2 on the vertical plane is in an empty state, and the emptied silt will be squeezed on the culvert 2. The two sides of the silted part cause local squeezing of the undiluted part, and it is impossible to form an effective comprehensive cleaning effect. The anti-vibration plate 16 arranged on the push-pull mechanism reduces the impact of the silting mechanism on the silting part structure when it moves along the axial direction of the culvert 2, so that the silting action does not have to follow the sequence of cleaning one place and then changing the position and then cleaning again, but can move along the axial direction of the culvert 2 while silting the side walls of the culvert 2, thereby achieving comprehensive cleaning of a certain area of ​​the side wall of the culvert 2 at the same time, avoiding the occurrence of local squeezing, and effectively improving the silting effect.

[0025] like Figures 5 to 7 As shown, the displacement assembly 8 includes a shell 81 fixedly connected to the shockproof plate 16, a support plate 82 is fixedly connected inside the shell 81, four slideways 83 are evenly arranged on the support plate 82 along the circumferential direction, a rotating block 84 is rotatably connected to the middle of the support plate 82, the top edge of the rotating block 84 is adapted to each slideway 83 and is rotatably connected to a connecting rod 85, a roller member 86 is slidably connected inside the slideway 83, a roller member 86 is installed on the outer side of the shell 81, the roller member 86 is located on one side inside the shell 81 and is rotatably connected to one end of the connecting rod 85, a cylinder 2 87 is installed between the tops of the two opposite roller members 86, and the cylinder 2 87 is electrically connected to the electric control box 7; It should be noted that the connecting objects connecting the two relative roller members 86 include but are not limited to the second cylinder 87 and the spring, which are used to adapt to the inner wall diameter of the culvert 2, and rely on the elastic force of the spring itself or the expansion and contraction amount of the telescopic rod of the second cylinder 87 by the electric control box 7 to achieve the effect of each roller fitting the inner wall of the culvert 2; specifically, the electric control box 7 adjusts the expansion and contraction amount of the telescopic rod of the second cylinder 87, and the rotating block 84 rotates accordingly, and when rotating, the roller member 86 is pushed to move along the slideway 83 until the roller of the roller member 86 located outside the shell 81 fits the inner wall of the culvert 2, completing the adaptive adjustment of the culvert 2, and performing In a further step, since the push-pull mechanism is installed on one side of the end wall 1 through screws and the silt cleaning plate 6, and the installation positions on both sides of the silt cleaning plate 6 are in a variable state due to the influence of the notch 11, the silt cleaning plate 6 is a detachable structure and a replaceable part, so the silt cleaning mechanism can be installed at the end wall 1 of the diameter of the culvert 2 of different specifications by replacing the silt cleaning plate 6, and when installed at different positions, the displacement component 8 in the culvert 2 for assisting the movement of the cleaning component 9 can be adaptively fitted to the inner wall of the pipe at the same time, that is, the cooperation of the silt cleaning plate 6, the notch 11 and the displacement component 8 improves the adaptability of the device to the cleaning of culverts 2 of different specifications.

[0026] The cleaning assembly 9 includes a rotating motor 91 installed in the housing 81, the rotating motor 91 is electrically connected to the electric control box 7, the output end of the rotating motor 91 penetrates the housing 81 and extends to the outside, one side of the output end of the rotating motor 91 is fixedly connected to a rotating shaft 92, the side of the rotating shaft 92 away from the rotating motor 91 is evenly connected to four side arms 93 in a circumferential direction, the side of the rotating shaft 92 close to each side arm 93 is fixedly connected to a supporting ring 94, the supporting ring 94 is adapted to each side arm 93 and is rotatably connected to a spring seat 95, a wall spring 96 is installed between each spring seat 95 and one end of the side arm 93, and one end of the side arm 93 is rotatably connected to a wiper block 97; It should be noted that the cleaning assembly 9 relies on the inherent elasticity of the wall-affecting spring 96 to push the outer end of the side arm 93 to rotate in a direction away from the central rotating shaft 92 until it is opened to the point where the wiper blocks 97 installed on each top abut against the inner side wall of the culvert 2. The staff then drives the rotating motor 91 by operating the electrical control box 7 to drive the rotating shaft 92 to rotate, and each wiper block 97 then dredges the inner wall of the culvert 2.

[0027] Working principle of the present invention: When the water flow inside the culvert 2 needs to be discharged, the staff rotates the rotating handle 51 to drive the central screw 52 to move in a vertical position. During the movement, the gate 54 installed at the bottom of the screw 52 immediately controls the opening and closing of the gate 10 until the water flow is discharged. After the discharge is completed, the debris accumulated inside the culvert 2 needs to be periodically cleaned, and the gate 54 is in an open state at this time; Then, the dredging plate 6 is connected to the push-pull mechanism, and then the dredging plate 6 is positioned and installed between the two notches 11 at a height suitable for dredging, and then the electric control box 7 is started. The shifting component 8 of the dredging mechanism is now located in the culvert 2, and the rollers of each roller member 86 are in contact with the inner wall of the culvert 2 under the action of electric control. The push-pull cylinder 14 of the push-pull mechanism drives the dredging mechanism to make reciprocating motions along the direction of the central axis of the culvert 2. When the dredging mechanism is located inside the culvert 2, it can always be stably supported. At the same time, the rotating motor 91 rotates to dredge the inner wall of the culvert 2. Since the rotating motor 91 can only perform fixed-point cleaning on a certain vertical surface of the culvert 2 when it rotates, a shockproof plate 16 is installed at the connection between the push-pull mechanism and the dredging mechanism, so that the dredging mechanism is reciprocated by the push-pull mechanism along the central axis of the culvert 2 while performing the dredging action, so as to achieve synchronous cleaning of a certain area inside the culvert 2 and improve the dredging effect. After the dredging is completed, the dredging plate 6 is removed, the dredging mechanism and the push-pull mechanism are taken out, and the rotating handle 51 is rotated in the reverse direction to close the gate 10 again.

[0028] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
