Abstract
Description
Technical Field
[0001] This application relates to the field of water conservancy engineering technology, and in particular to a dam gate. Background Technology
[0002] Gates are an important component of hydraulic structures, serving as control devices for closing and opening water discharge channels. Installed on dams, they are commonly used to intercept water flow, control water levels, and remove floating debris. Gates are primarily installed within gate slots on the dam, and a drive mechanism propels the gate to slide within the slot, where it is then inserted into a connecting slot at the bottom of the dam, thus opening and closing the water discharge channel.
[0003] During prolonged closures of the spillway, a large amount of debris often accumulates on one side of the gate. To address this issue, the traditional method is to slide a collection box onto one side of the gate, ensuring close contact. In operation, the collection box is submerged at the bottom of the dam to capture and collect the debris that has floated and accumulated on the gate side over time. As silt and sand gradually adhere to the surface, the debris sinks into the collection box. When it's time to clean the collection box, it is raised, allowing for a secondary cleaning of the debris on the gate side during this process.
[0004] However, during the process of removing the collection box from the dam for cleaning, garbage may re-accumulate on one side of the gate. When the collection box is put back into the dam, the garbage is pressed against the bottom wall of the collection box and sinks to the bottom of the dam, thus affecting the cleaning effect on the garbage on the side of the gate. Utility Model Content
[0005] In order to improve the cleaning effect of garbage on one side of the gate, this application provides a dam gate.
[0006] The technical solution for a dam gate provided in this application is as follows:
[0007] A dam gate, installed on a dam, includes a gate body and a collection box vertically sliding on the dam, a first driving device for driving the gate body to slide, and a second driving device for driving the collection box to slide; the collection box has openings at both the top and bottom, and the collection box abuts against one side of the gate body; a baffle plate is rotatably installed at the bottom of the collection box, and the collection box is equipped with a fixing structure for driving the baffle plate to cover the opening at the bottom of the collection box.
[0008] By adopting the above technical solution, openings are provided on both the top and bottom sides of the collection box, so that as the collection box sinks to the bottom of the dam, the garbage can pass through the openings on the top and bottom sides of the collection box to keep floating on the surface of the river water, thereby avoiding the garbage being pressed into the bottom of the dam by the collection box.
[0009] After the collection box is sunk to the bottom of the dam, a baffle is placed over the opening at the bottom of the collection box by a fixed structure. This allows the garbage that has sunk to the bottom of the dam to enter the collection box for collection. When the collection box is raised, the baffle can prevent the garbage from being exposed from the bottom of the collection box and can also collect the garbage floating on the surface of the river, thus improving the cleaning effect on the garbage on one side of the gate body.
[0010] Optionally, the baffle is rotatably mounted on the side of the collection box away from the gate body, and the fixing structure includes an electric push rod installed on the collection box. The moving direction of the movable plug of the electric push rod is perpendicular to the moving direction of the collection box. When the bottom of the collection box is closed, the movable plug of the electric push rod is slidably connected to the side of the baffle away from the collection box.
[0011] By adopting the above technical solution, after the collection box is sunk to the bottom of the dam, the movable plug of the electric push rod is driven to move towards one side of the collection box, which allows the baffle to rotate towards one side of the collection box and cover the opening at the bottom of the collection box.
[0012] Optionally, the fixing structure includes a first motor installed in the collection box and a pull rope installed on the output shaft of the first motor, the pull rope being connected to the side of the baffle away from its hinge.
[0013] By adopting the above technical solution, when it is necessary to use the baffle to close the opening at the bottom of the collection box, the output shaft of the first motor is turned on, and the pull rope can be wound around the surface of the output shaft of the first motor to reduce the length of the pull rope; at this time, the baffle rotates along its hinge with the collection box toward one side of the collection box, so that the baffle can cover the opening of the collection box.
[0014] Optionally, a torsion spring is provided at the hinge between the baffle and the collection box, and the elastic force of the torsion spring is used to drive the baffle to rotate along its own hinge towards the side away from the collection box.
[0015] By adopting the above technical solution and setting torsion springs, the free rotation of the shielding plate during the process of the collection box entering the bottom of the dam can be reduced, thereby reducing the possibility of garbage being pressed into the bottom of the dam by the collection box.
[0016] Optionally, a rubber layer is provided at the contact point between the baffle and the bottom wall of the collection box.
[0017] By adopting the above technical solution and setting a rubber layer, the sealing performance of the baffle covering the bottom wall of the collection box can be increased, reducing the possibility of waste flowing out into the outside through the gap between the collection box and the folding plate during the lifting of the collection box.
[0018] Optionally, the baffle plate has water-permeable holes.
[0019] By adopting the above technical solution, when the collection box is removed from the dam, the water-permeable holes can allow the water inside the collection box to flow out to the outside, improving the convenience of cleaning the garbage inside the collection box.
[0020] Optionally, the collection box is provided with a guide plate, one end of which abuts against the side wall of the gate body.
[0021] By adopting the above technical solution and setting a guide plate, when the collection box is lifted upward and taken out from inside the dam, the guide plate can guide the garbage that has gathered on one side of the gate body into the collection box, which usually improves the collection efficiency of the collection box.
[0022] Optionally, the second drive device includes a mounting frame, a linear module mounted on the mounting frame, and an electric hoist mounted on the linear module, wherein the electric hoist is connected to the collection box.
[0023] By adopting the above technical solution, when the collection box is removed from inside the dam, the electric hoist can lift the collection box upwards and raise it to the top of the dam, and then drive the linear module to transfer the collection box to the ground, so that the staff can clean the garbage in the collection box.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. By setting openings on both the top and bottom sides of the collection box, the garbage can pass through the openings on the top and bottom sides of the collection box and remain floating on the surface of the river water as the collection box is sunk to the bottom of the dam, thus avoiding the garbage being pressed into the bottom of the dam by the collection box.
[0026] 2. By setting up guide plates, when the collection box is lifted upwards and taken out from inside the dam, the guide plates can guide the garbage that has gathered on one side of the gate body into the collection box, which usually improves the collection efficiency of the collection box.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] Example 1:
[0034] This application discloses a dam gate.
[0035] Reference Figure 1 A dam gate is installed on a dam 1 and includes a gate body 2, a collection box 3, a first driving device 4 and a second driving device 5. Gate slots are provided on opposite sides of the dam 1, and the gate body 2 is vertically inserted into the gate slots. In this embodiment, the first driving device 4 includes a second motor 41, a screw 42 and a threaded sleeve 43. A threaded groove is provided on the top of the dam 1, and the threaded rod is threaded into the threaded groove and rotatably connected to the gate body 2.
[0036] A threaded sleeve 43 is rotatably mounted on the top of the dam 1 and fitted onto the outer wall of the threaded rod. In this embodiment, a first gear 44 is provided on the outer wall of the threaded sleeve 43, and the axis of the first gear 44 and the axis of the threaded sleeve 43 are coaxially arranged. A second motor 41 is mounted on the top of the dam 1, and a second gear 45 for meshing with the first gear 44 is installed on the output shaft of the second motor 41. By driving the second motor 41, the threaded sleeve 43 can be rotated. Since the threaded sleeve 43 is threadedly engaged with the threaded rod, the gate body 2 can slide within the gate slot, thereby playing the role of opening and closing the flood discharge sleeve.
[0037] The dam 1 body is provided with a limiting plate 11. The extension direction of the limiting plate 11 is in the same direction as the sliding direction of the gate plate. The collection box 3 is clamped between the limiting plate 11 and the gate body 2. The second driving device 5 is used to drive the collection box 3 to slide vertically between the limiting plate 11 and the gate body 2. By setting the limiting plate 11, the collection box 3 can be kept in contact with one side of the gate body 2, which improves the stability of the collection box 3 sliding in the dam 1.
[0038] The second drive device 5 includes a mounting frame 51, a linear module 53, and an electric hoist 52. The mounting frame 51 is mounted on the top of the dam 1, and the linear module 53 is mounted on the mounting frame 51 to drive the electric hoist 52 to slide from the top of the dam 1 to the ground. The chain of the electric hoist 52 is connected to the collection box 3 to drive the collection box 3 into the bottom of the dam 1.
[0039] Reference Figure 2 The collection box 3 has openings 31 at both the top and bottom, and the collection box 3 is provided with a baffle 6 for covering the bottom opening 31 of the collection box 3. In this embodiment, the baffle 6 is hinged to the side of the collection box 3 away from the gate body 2. The baffle 6 can reduce the situation where garbage falls off the bottom of the collection box 3 when the collection box 3 moves upward. The baffle 6 has water-permeable holes 61, which can allow the river water entering the collection box 3 to flow out to the outside, so as to facilitate the treatment of garbage in the collection box 3.
[0040] A guide plate 32 is provided on the top of the collection box 3 and on the side near the gate body 2. The end of the guide plate 32 away from the collection box 3 is inclined toward the side of the gate body 2 and can abut against the gate body. By providing the guide plate 32, when the collection box 3 is lifted up and taken out from the dam 1, the guide plate 32 can guide the garbage that has gathered on the side of the gate body 2 into the collection box 3, which generally improves the garbage collection effect of the collection box 3.
[0041] A rubber layer 62 is provided on the side of the baffle 6 near the collection box 3. The rubber layer 62 is used to abut against the bottom of the collection box 3. The rubber layer 62 can increase the sealing between the baffle 6 and the collection box 3, and reduce the possibility of garbage flowing out of the outside through the gap between the collection box 3 and the baffle 6 during the process of removing the collection box 3 from the dam 1.
[0042] The collection box 3 is provided with a fixing structure 7, which is used to drive the baffle plate 6 to rotate between itself and the collection box 3 to cover the opening 31 at the bottom of the collection box 3. In this embodiment, the fixing structure 7 includes a connecting frame 71 and an electric push rod 72. The electric push rod 72 has a waterproof function. The connecting frame 71 is installed on the side of the collection box 3 away from the gate body 2. The connecting frame 71 is provided with a protective shell 77. The electric push rod 72 is installed inside the protective shell 77. The protective shell 77 is provided to reduce the electric push rod 72 from being immersed in river water for a long time. The movable plug of the electric push rod 72 passes through the protective shell 77 and is connected to the baffle plate 6.
[0043] When the bottom of the collection box 3 is in the open state 31, the side of the baffle plate 6 away from the gate body 2 is provided with a groove 63, and a slider 64 is slidably installed in the groove 63; the movable plug of the electric push rod 72 is rotatably connected to the slider 64.
[0044] The implementation principle of Embodiment 1 of this application is as follows:
[0045] By providing openings 31 on both the top and bottom sides of the collection box 3, the garbage can pass through the openings 31 on the top and bottom sides of the collection box 3 to remain floating on the surface of the river water during the process of the collection box 3 sinking to the bottom of the dam 1, thereby avoiding the garbage being pressed into the bottom of the dam 1 by the collection box 3.
[0046] When the collection box 3 sinks to the bottom of the dam 1, the movable plug of the electric push rod 72 is driven to move towards the side of the collection box 3, which allows the shield 6 to rotate towards the side of the collection box 3 and cover the opening 31 at the bottom of the collection box 3; thereby preventing garbage from being exposed from the bottom of the collection box 3 and enabling secondary collection of garbage floating on the surface of the river water, improving the cleaning effect of garbage on one side of the gate body 2.
[0047] Example 2:
[0048] This application discloses a dam gate.
[0049] Reference Figure 3 The difference between Embodiment 2 and Embodiment 1 is that a torsion spring (not shown in the figure) is provided at the hinge of the baffle plate 6 and the collection box 3, and a positioning plate is provided on the side of the collection box 3 away from the gate body; the elastic force of the torsion spring is used to drive the baffle plate 6 to rotate along its own hinge towards the side away from the collection box 3 and abut against the positioning plate, so as to keep the bottom opening 31 of the collection box 3 in the open state and reduce the situation where the baffle plate 6 rotates freely during the process of the collection box 3 entering the bottom of the dam 1.
[0050] Simultaneously refer to Figure 4 The fixing structure 7 is provided in two sets, and both sets of fixing structures 7 are installed inside the collection box 3. The fixing structure 7 includes a first motor 73, a pull rope 75 and a housing 74. The housing 74 is installed on the inner wall of the collection box 3. The first motor 73 is a waterproof motor and is installed inside the housing 74. One end of the pull rope 75 is connected to the output shaft of the first motor 73. The housing 74 has a through hole 76 for the pull rope 75 to pass through. The end of the pull rope 75 away from the first motor 73 passes through the through hole 76 and is connected to the side of the baffle plate 6 away from its hinge.
[0051] The implementation principle of Embodiment 2 of this application is as follows:
[0052] When it is necessary to use the baffle plate 6 to close the opening 31 at the bottom of the collection box 3, the output shaft of the first motor 73 is turned on, and the pull rope 75 can be wound around the surface of the output shaft of the first motor 73 to reduce the length of the pull rope 75; at this time, the baffle plate 6 rotates along its hinge with the collection box 3 toward one side of the collection box 3, so that the baffle plate 6 can cover the opening 31 of the collection box 3.
[0053] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
