Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering gate technology, and in particular to a lifting water conservancy engineering gate for water conservancy projects. Background Technology

[0002] A lifting gate is a device used to regulate and control water flow and ensure water level. It is widely used in water conservancy projects such as reservoirs, rivers, irrigation and drainage systems. It is driven by mechanical or electric power to raise and lower the gate in order to achieve the purpose of flow regulation or water level control.

[0003] When using existing lifting-type hydraulic gates, staff will activate the lifting mechanism on the gate frame and control the raising and lowering of the screw rod according to the actual water level and drainage channel conditions, thereby adjusting the height of the gate plate and thus regulating the flow of water through the gate. However, in actual use, it has been found that sand, gravel, and other foreign objects contained in general rivers and channels will enter the lifting gap of the gate frame with the water flow, thus obstructing the raising and lowering of the gate plate and potentially damaging the mechanical parts of the gate, affecting the normal use of the equipment and increasing operating costs. Utility Model Content

[0004] The technical problem this utility model aims to solve is that foreign objects such as sand and gravel are often found in general river channels and canals. Some of these foreign objects will enter the lifting gap of the gate frame as the water flows, thus hindering the raising and lowering of the gate and possibly damaging the mechanical parts of the gate, affecting the normal use of the equipment and increasing the cost of use.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a lifting gate for water conservancy projects, including a gate frame, a gate plate provided on the inner wall of the gate frame, a screw rod installed on the top of the gate plate, a lifting mechanism installed on the surface of the gate frame, wherein the lifting mechanism is connected to the screw rod, and an auxiliary device is provided on the water inlet side surface of the gate frame, wherein the auxiliary device intercepts and processes sand and gravel foreign objects contained in the flowing water by means of a rotating plate and an arc plate.

[0006] The aforementioned components achieve the following effects: when a gate is installed in the water channel of a water conservancy project to control and regulate the water level, the elevator is activated according to the actual situation, thereby driving the screw and gate plate to lift and lower, adjusting the size of the gate frame water outlet, and simultaneously operating the auxiliary device to intercept and collect sand and gravel in the flowing water.

[0007] Preferably, the auxiliary device includes a mounting rod, wherein a plurality of evenly distributed rotating plates are fixedly connected to the arc surface of the mounting rod, and an assembly plate is rotatably disposed through the arc surfaces at both ends of the mounting rod. The assembly plate is fixedly connected to the side of the gate frame. A servo motor is mounted on the surface of the gate frame, wherein a sprocket is mounted on the output end of the servo motor and one end of the rotating rod, and a chain is mounted on the surface of the two sprockets. An arc-shaped plate is mounted on one side surface of the gate frame, wherein a baffle is fixedly connected to one side of the arc-shaped plate.

[0008] The effect achieved by the above components is that when the gates used in water conservancy projects are used in water channels, they can intercept and collect sand and gravel in the flowing water in a timely and efficient manner, so as to ensure the purity of the flowing water as much as possible. This makes it less likely for foreign objects and sand to enter the sliding groove of the gate frame, ensuring the normal use of the gate and preventing damage.

[0009] Preferably, protective plates are fixedly connected to both sides of the surface of the arc-shaped plate, wherein the protective plates enhance the performance of the arc-shaped plate.

[0010] The effect achieved by the above components is that the sand and gravel collected by the arc plate are better stored on the inside by the setting of the protective plate, and are not easy to slide away from the sides and enter the groove of the gate frame.

[0011] Preferably, the auxiliary device further includes a reinforcing plate installed at one end of the rotating plate, wherein the reinforcing plate improves the interception effect of the rotating plate.

[0012] The effect achieved by the above components is that by setting up the reinforcing plate, one end of the rotating plate forms a certain groove shape, which can better block sand and gravel when intercepting them, and thus better collect them in the inner side of the arc-shaped plate.

[0013] Preferably, the auxiliary device includes a stabilizing plate mounted on the surface of the chain, wherein the stabilizing plate is fixedly connected to the surface of the mounting plate.

[0014] The effect achieved by the above components is that, through the setting of the stabilizing plate, the chain is less likely to loosen or shift under the drive of the sprocket, thereby ensuring the normal rotation of the mounting rod and ensuring the interception and treatment of sand and gravel.

[0015] Preferably, a reinforcing device is provided on the surface of the gate frame on the side facing the water outlet. The reinforcing device includes a combined plate, on the surface of which several evenly distributed protective plates are fixedly connected. A screw is threaded through both sides of the surface of the combined plate, and one end of the screw is rotatably disposed with respect to the surface of the gate frame.

[0016] The effect achieved by the above components is that when the gate equipment used in water conservancy projects is in use, it can provide a certain degree of protection for the gate plate, so that the gate plate is not easily deformed or damaged when the water flow impacts the gate plate, thus ensuring the normal use of the equipment.

[0017] Preferably, the reinforcing device further includes a reinforcing pad installed on one side of the protective plate, wherein the reinforcing pad improves the protective effect of the protective plate.

[0018] The effect achieved by the above components is that, through the setting of the rubber reinforcing pad, the gate can be cushioned when it is pressed and contacted with the protective plate, thereby better protecting the gate.

[0019] Preferably, the reinforcing device further includes a stabilizing ring mounted on the arc surface of the screw, wherein the stabilizing ring raises the combined plate.

[0020] The effect achieved by the above components is as follows: by setting the stabilizing ring, when the rotating screw brings the protective plate and the gate plate surface into contact, the stabilizing ring on the rotating screw is pressed against the surface of the combined plate. At this time, the screw is not easy to rotate, which ensures the stability of the protective plate position and better prevents the gate plate from being deformed by impact.

[0021] The beneficial effects of this utility model are:

[0022] When the gate of this utility model is used in water conservancy projects, it can intercept and collect sand and gravel in the flowing water in a timely and efficient manner, so as to ensure the purity of the flowing water as much as possible. This makes it less likely for foreign objects and sand to enter the sliding groove of the gate frame, ensuring the normal use of the gate and preventing damage. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figure 1 and Figure 2 The diagram shows a lifting gate for a water conservancy project, comprising a gate frame 1, a gate plate 2 on the inner wall of the gate frame 1, a screw rod 3 installed on the top of the gate plate 2, a lifting mechanism 4 installed on the surface of the gate frame 1, the lifting mechanism 4 being connected to the screw rod 3, an auxiliary device 5 on the water inlet side of the gate frame 1, the auxiliary device 5 using a rotating plate 52 and an arc plate 57 to intercept sand and gravel in the flowing water, and a reinforcing device 6 on the water outlet side of the gate frame 1.

[0032] Figure 1 , Figure 2 and Figure 3The auxiliary device 5 shown includes a mounting rod 51, on which several evenly distributed rotating plates 52 are fixedly connected. Assembly plates 53 are rotatably mounted through the two ends of the mounting rod 51 on their respective arc surfaces. The assembly plates 53 are fixedly connected to the side of the gate frame 1. A servo motor 54 is mounted on the surface of the gate frame 1. A sprocket 55 is mounted on the output end of the servo motor 54 and one end of the rotating rod, respectively. A chain 56 is mounted on the surface of both sprockets 55. An arc-shaped plate 57 is mounted on one side of the gate frame 1, and a baffle 58 is fixedly connected to one side of the arc-shaped plate 57. When a gate is installed in the water channel of a water conservancy project to control and regulate the water level, the elevator 4 is activated according to the actual situation, thereby driving the screw 3 and the gate plate 2 to raise and lower, adjusting the size of the water outlet of the gate frame 1. Simultaneously, the servo motor 54 on one side of the gate frame 1 is activated. The motor 54, through the meshing connection of the sprocket 55 and the chain 56, causes the mounting rod 51 to rotate within the inner wall of the mounting plate 53, thereby causing several rotating plates 52 on the mounting rod 51 to rotate. When the rotating plates 52 rotate to a vertical position, they will always be higher than the horizontal plane. At this time, sand and gravel foreign objects that come with the water flow to the vicinity of the gate plate will be intercepted by the rotating plates 52 and enter the inner side of the arc plate 57 with the rotation of the rotating plates 52. They will be temporarily blocked and stored by the baffle 58 on one side of the arc plate 57. Then, the filtered water will flow from the opening below the gate plate 2 of the gate frame 1. When the gate used in the water conservancy project is used in the water channel, it can intercept and collect sand and gravel foreign objects in the water in a timely and efficient manner, ensuring the purity of the water as much as possible. This makes it less likely for foreign objects and sand to enter the sliding groove of the gate frame 1, ensuring the normal use of the gate and preventing damage.

[0033] Figure 1 , Figure 2 and Figure 3 Protective plates 510 are fixedly connected to both sides of the surface of the arc-shaped plate 57 shown. The protective plates 510 enhance the performance of the arc-shaped plate 57. By setting the protective plates 510, the sand and gravel collected by the arc-shaped plate 57 are better stored on the inner side and are less likely to slip away from the sides and enter the groove of the gate frame 1. The auxiliary device 5 also includes a reinforcing plate 59 installed at one end of the rotating plate 52. The reinforcing plate 59 improves the interception effect of the rotating plate 52. By setting the reinforcing plate 59, one end of the rotating plate 52 forms a certain groove shape, which can better block the sand and gravel when intercepting them, and thus better collect them in the inner side of the arc-shaped plate 57. The auxiliary device 5 includes a stabilizing plate 511 installed on the surface of the chain 56. The stabilizing plate 511 is fixedly connected to the surface of the mounting plate 53. By setting the stabilizing plate 511, the chain 56 is less likely to loosen or shift under the drive of the sprocket 55, thus ensuring the normal rotation of the mounting rod 51 and ensuring the interception and treatment of sand and gravel.

[0034] Figure 1 and Figure 4 The reinforcing device 6 shown includes a combination plate 61. Several evenly distributed protective plates 62 are fixedly connected to the surface of the combination plate 61. Screws 63 are threaded through both sides of the surface of the combination plate 61. One end of the screw 63 is rotatably set with the surface of the gate frame 1. When the hydraulic gate is installed in the hydraulic canal, the screws 63 on both sides of the combination plate 61 are installed on both sides of the surface of the gate frame 1. Then, the screws 63 on both sides are rotated. The rotation of the screws 63 will drive the combination plate 61 to move closer to the gate plate 2 until the several protective plates 62 on the surface of the combination plate 61 are close to one side of the gate plate 2. At this time, when the hydraulic gate equipment is in use, it can form a certain protective effect on the gate plate 2, so that the gate plate 2 is not easily deformed and damaged when the water flow impacts the gate plate 2, thus ensuring the normal use of the equipment.

[0035] Figure 1 and Figure 4 The reinforcing device 6 shown also includes a reinforcing pad 64 installed on one side of the protective plate 62. The reinforcing pad 64 improves the protective effect of the protective plate 62. The rubber reinforcing pad 64 provides a certain buffer when the gate plate 2 is pressed against the protective plate 62, thus better protecting the gate plate 2. The reinforcing device 6 also includes a stabilizing ring 65 installed on the arc surface of the screw 63. The stabilizing ring 65 raises the combined plate 61. With the stabilizing ring 65, when the screw 63 is rotated to bring the protective plate 62 into contact with the surface of the gate plate 2, the stabilizing ring 65 on the screw 63 is rotated to press against the surface of the combined plate 61. At this time, the screw 63 is less likely to rotate, ensuring the position of the protective plate 62 is stable and better preventing the gate plate 2 from being deformed by impact.

[0036] Working principle: When a gate is installed in the water channel of a water conservancy project to control and regulate the water level, the hoist 4 is activated according to the actual situation, thereby driving the screw 3 and the gate plate 2 to raise and lower the height, adjusting the size of the water outlet of the gate frame 1. At the same time, the servo motor 54 (model ABB) on one side of the gate frame 1 is operated to start the gate frame 1. The sprocket 55 and chain 56 mesh together to make the mounting rod 51 rotate in the inner wall of the mounting plate 53, thereby causing several rotating plates 52 on the mounting rod 51 to rotate. When the rotating plates 52 rotate to the vertical position, they will always be higher than the horizontal plane. At this time, sand and gravel foreign objects that come to the vicinity of the gate plate with the water flow will be intercepted by the rotating plates 52 and enter the inner side of the arc plate 57 with the rotation of the rotating plates 52. They will be blocked and temporarily stored by the baffle 58 on one side of the arc plate 57. Then, the filtered water will flow from the opening below the gate plate 2 of the gate frame 1. When the gate used in the water conservancy project is used in the water channel, it can intercept and collect sand and gravel foreign objects in the water in a timely and efficient manner, so as to ensure the purity of the water as much as possible. This makes it less likely for foreign objects and sand to enter the sliding groove of the gate frame 1, ensuring the normal use of the gate and preventing damage.

[0037] When a hydraulic gate is installed in a water conservancy channel, the screws 63 on both sides of the combined plate 61 are installed on both sides of the gate frame 1. Then, the screws 63 on both sides are rotated. The rotation of the screws 63 will drive the combined plate 61 to move closer to the gate plate 2 until several protective plates 62 on the surface of the combined plate 61 and one side of the gate plate 2 are close to each other. At this time, when the hydraulic gate equipment is in use, it can form a certain protective effect on the gate plate 2, so that the gate plate 2 is not easily deformed and damaged when the water flow impacts the gate plate 2, thus ensuring the normal use of the equipment.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
