Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically a lock gate structure with self-cleaning function. Background Technology

[0002] Ship locks are crucial facilities in water conservancy projects and shipping engineering, used to regulate water level differences and ensure the safe and efficient passage of ships. As the core component of a ship lock, the opening and closing performance of the lock gate directly affects navigation efficiency, energy consumption, and long-term operational reliability. Currently, the most widely used type is the miter gate, but its structure and working principle have several limitations:

[0003] A miter gate typically consists of two gate leaves that rotate around a vertical axis. It relies on the mutual support of the gate leaves when they are closed to resist water pressure. However, miter gates must overcome enormous water pressure during opening and closing, especially in high-head ship locks. The drive mechanism (such as a hydraulic cylinder or motor) needs to provide extremely high torque, resulting in a significant increase in energy consumption. In addition, miter gates rely on a hinged support structure. After long-term operation, the hinge points are prone to jamming due to wear or corrosion caused by mud and sand, requiring frequent maintenance and resulting in high maintenance costs. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a lock gate that reduces the failure rate of the gate and can achieve automatic cleaning.

[0005] The technical solution adopted by this utility model to achieve the above objectives is: a lock gate structure with self-cleaning function, including a dam body, a gate plate, a traction mechanism, and a cleaning component. The dam body is provided with a gate opening, and a lock chamber is provided on both sides of the gate opening on the dam body. Each lock chamber is provided with a set of gate plates. The dam body is provided with a traction mechanism corresponding to each set of gate plates. The traction mechanism cooperates with the gate plate so that the traction mechanism can pull the gate plate to move linearly. Each lock chamber is provided with the cleaning component.

[0006] In the above technical solution, the bottom of the dam body is provided with a track, which includes a track groove and track plates located on both sides of the track groove. The bottom of each set of gate plates is rotatably connected to multiple sets of bottom wheels, which are located in the track groove. In this way, when the traction mechanism pulls the gate plate to move, the friction force of the gate plate can be reduced, thereby reducing the traction force required by the traction mechanism. Furthermore, the track plates abut against the sides of the gate plate to ensure the sealing effect of the bottom of the gate plate and prevent upstream water from overflowing when the gate plate is closed.

[0007] In the above technical solution, the traction mechanism adopts the following structure:

[0008] The traction mechanism includes a housing, a reduction motor, a traveling gear, and a traveling rack. A sliding rail is fixedly connected to the top surface of the dam body, and the traveling rack is fixedly connected to one side of the sliding rail on the top surface of the dam body. The housing is slidably connected to the sliding rail, and the reduction motor is fixedly connected inside the housing. A drive shaft is fixedly connected to the power output end of the reduction motor, and the traveling gear is fixedly connected to the drive shaft. The traveling gear meshes with the traveling rack.

[0009] A movement port is provided on the top surface of the dam body, which communicates with the gate reservoir. A connecting frame is fixedly connected to the machine box, and the connecting frame passes through the movement port and is fixedly connected to the gate plate.

[0010] When the above-mentioned traction mechanism is used, the reduction motor can drive the traveling gear to rotate. In this way, with the traveling gear and the traveling rack working together, the chassis can move linearly on the sliding rail, thus pulling the gate to move linearly.

[0011] In the above technical solution, the cleaning component adopts the following structure:

[0012] The cleaning assembly includes a cleaning roller, a drive gear, and a drive rack. Two sets of cavities are fixedly connected to the gate near its port. A set of cleaning rollers is rotatably connected inside each set of cavities. The drive gear is fixedly connected to the roller shaft of each set of cleaning rollers. The gate plate has a groove corresponding to the drive gear. The drive rack is fixedly connected inside the groove. The drive gear and the drive rack are meshed. The cleaning roller abuts against the side wall of the gate plate.

[0013] When the above-mentioned cleaning components are used, when the traction mechanism pulls the gate plate into the gate chamber, the drive rack can drive the drive gear to rotate, which in turn causes the cleaning roller to rotate. The rotating cleaning roller can then clean the side wall of the gate plate.

[0014] Furthermore, the drive gear is fixedly connected to the top roller shaft of the cleaning roller, which avoids the reduced sealing performance of the gate due to the groove being located at the bottom.

[0015] The beneficial effects of this utility model are:

[0016] 1. The gate is driven to move linearly by a traction mechanism, so that the gate enters the gate chamber and opens the gate. Compared with the opening and closing of the miter gate in the existing technology, the gate only needs to overcome the edge friction resistance when moving linearly, without having to resist the pressure of a large area of ​​water flow, which greatly reduces the energy consumption of opening and closing. In addition, the linear motion mechanism is simpler than the rotation structure of the miter gate, reduces the wear of the hinge point, has a low failure rate, and reduces maintenance costs.

[0017] 2. When the traction mechanism pulls the gate to close, the drive rack drives the drive gear to rotate, which in turn causes the cleaning roller to rotate. The rotating cleaning roller can clean the surface of the gate. This structure can use the traction force of the gate movement to drive the cleaning roller to rotate, without the need for an independent motor or hydraulic system, saving energy and equipment costs. By removing mud, sand, algae and other attachments from the surface of the gate, manual cleaning can be reduced, thereby extending the service life of the gate and ensuring the airtightness of the gate.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 7 As shown, a lock gate structure with self-cleaning function includes a dam body 100, a gate plate 200, a traction mechanism 300, and a cleaning component 400. The dam body 100 has a gate opening 101, and gate storage 102 are symmetrically arranged on both sides of the gate opening 101. Each set of gate storage 102 contains a set of gate plates 200. The size of the gate plates 200 matches the gate opening 101 and is used to close or open the gate opening 101.

[0028] The bottom of the dam body 100 is pre-embedded with a track 103 along the movement direction of the gate 200. The track 103 consists of a track groove 1031 and track plates 1032 on both sides. Multiple sets of bottom wheels 201 are installed at the bottom of the gate 200 through a rotating shaft. The bottom wheels 201 are embedded in the track groove 1031 and roll to reduce the frictional resistance when the gate 200 moves. The track plates 1032 on both sides are in close contact with the bottom edge of the gate 200 to ensure that the upstream water does not leak from the bottom when the gate 200 is closed.

[0029] Furthermore, a traction mechanism 300 is provided on the dam body 100 corresponding to the gate 200. The traction mechanism 300 includes a housing 301, a reduction motor 302, a traveling gear 303, and a traveling rack 304. That is, a sliding rail 305 and a traveling rack 304 are fixed on the top surface of the dam body 100. The traveling rack 304 is arranged parallel to the sliding rail 305. The housing 301 is slidably connected to the sliding rail 305, and the reduction motor 302 is fixed inside it. The output end of the reduction motor 302... A fixed drive shaft is connected, and a traveling gear 303 is fixed at the end of the drive shaft. The traveling gear 303 meshes with a traveling rack 304. A movement port 104 is opened on the top surface of the dam body 100. The housing 301 passes through the movement port 104 and is fixed to the top of the gate 200 through a connecting frame 306. When the reduction motor 302 starts, the traveling gear 303 rolls along the traveling rack 304, driving the housing 301 and the gate 200 to move linearly along the sliding rail 305, thereby realizing the opening and closing of the gate 101.

[0030] In addition, the gate housing 102 is also equipped with a cleaning assembly 400, which includes a cleaning roller 401, a drive gear 402, and a drive rack 403. Two sets of recesses 105 are symmetrically opened on the side wall of the gate housing 102 near the port. The cleaning roller 401 is rotatably connected to the recesses 105 through bearings. The drive gear 402 is fixed on the top roller shaft of the cleaning roller 401. The gate plate 200 has a groove 202 on the side corresponding to the position of the drive gear 402. The drive rack 403 is fixed in the groove 202. When the gate plate 200 retracts into the gate housing 102, the drive rack 403 meshes with the drive gear 402, driving the cleaning roller 401 to rotate. The surface of the cleaning roller 401 is covered with hard bristles or rubber scrapers. During the rotation, it scrapes the side of the gate plate 200 to remove the attached substances. The groove 202 is located on the upper part of the side of the gate plate 200 to avoid affecting the bottom sealing.

[0031] In summary, this embodiment discloses a lock gate structure with self-cleaning function. Specifically, when the gate 101 is opened, the reduction motor 302 drives the traveling gear 303 to rotate along the traveling rack 304, causing the gate plate 200 to move from the gate 101 into the lock chamber 102. As the gate 101 gradually opens and the gate plate 200 moves, the driving rack 403 drives the cleaning roller 401 to rotate, automatically cleaning the surface of the gate plate 200 and avoiding the attachments from affecting the lifespan of the gate plate 200 and the sealing performance between the gate plate 200 and the lock chamber 102, thus reducing the sealing effect of the gate 101.

[0032] When the gate 101 is closed, the geared motor 302 rotates in the reverse direction, causing the traction mechanism 300 to drive the gate plate 200 to move from the gate 102 to the gate 101 position until the end faces of the two sets of gate plates 200 abut against each other.

[0033] Compared with existing herringbone gates, the gate 200 with the above structure only needs to overcome edge friction resistance and does not need to resist the pressure of large-area water flow, which significantly reduces the energy consumption for opening and closing. Its linear motion mechanism can reduce wear at the hinge point, has a low failure rate, and is easy to maintain. Furthermore, the cleaning roller 401 is driven by the motion power of the gate 200, which requires no additional energy and reduces the cost of manual maintenance.
