Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering equipment technology, and in particular to a gate bottom groove debris removal device. Background Technology

[0002] Over long-term operation, the bottom trench of the intake gate of a hydropower station easily accumulates sediment, gravel, aquatic organisms, and other debris. This sediment can cause the gate to not close tightly when closed, severely affecting the drainage efficiency of the generator flow channels, thus delaying unit maintenance schedules and threatening the safe and stable operation of the power station. Furthermore, the debris accumulated in the bottom trench of the gate accelerates the wear of seals, shortening the equipment's lifespan. Therefore, regularly and thoroughly cleaning the gate trench is a crucial maintenance task to ensure the normal operation of the hydropower station.

[0003] Currently, gate trench cleaning mainly relies on manual diving operations, with divers carrying tools for underwater cleaning. This method poses significant safety hazards, as divers face harsh environmental conditions such as strong currents and low visibility, making the operation extremely risky. Furthermore, manual cleaning is inefficient, time-consuming, costly, and limited by the divers' physical strength, making thorough cleaning difficult. Especially during the high-flow-rate conditions of the flood season, traditional manual cleaning methods are often impractical, severely impacting the efficiency of power plant emergency maintenance. Therefore, existing technologies need improvement and development. Utility Model Content

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.

[0023] In hydropower station operation, gate systems typically include segmented and integral designs. The segmented design consists of an upper gate section and a lower gate section 100, which can be independently controlled. The integral design does not have upper and lower gates. The gate described in this invention includes the lower gate section of a segmented gate or the lower part of an integral gate. Because the lower gate section 100 or the lower part of an integral gate is constantly in an underwater working environment, it is particularly prone to accumulating sediment, gravel, and other deposits in the gate slot, and also fostering various aquatic organisms. This accumulation of debris can lead to incomplete sealing when the gate is closed, affecting the effective drainage of the generator flow channel, significantly extending generator maintenance time, and in severe cases, potentially jeopardizing the safe and stable operation of the power station. Currently, the industry commonly uses manual underwater cleaning, where professional divers carry cleaning tools for underwater operations. However, this method has significant drawbacks, including low efficiency, high safety risks, and great dependence on environmental conditions. To address the aforementioned issues, this embodiment provides a gate bottom groove debris removal device.

[0024] Please see Figure 1 and Figure 2In one embodiment of this utility model, a gate bottom groove debris removal device is disclosed, including a sliding assembly 110, a high-pressure water gun assembly 120, and a traction assembly 130. The sliding assembly 110 includes two parallel slide rails 111 and two sliders 112. The two slide rails 111 are disposed on the gate near the gate bottom groove, and the length direction of the slide rails 111 is parallel to the bottom edge of the gate. The two sliders 112 are slidably disposed on the two slide rails 111 respectively. The high-pressure water gun assembly 120 is disposed on the two sliders 112, and its movement is achieved by the sliding of the sliders 112 on the slide rails 111. The traction assembly 130 includes a first fixed pulley 131, a second fixed pulley 132, a first traction rope 133, and a second traction rope 134. The system includes a first guide pulley 135 and a second guide pulley 136; a first fixed pulley 131 and a second fixed pulley 132, which are respectively disposed at both ends of the slide rail 111; the first guide pulley 135 and the second guide pulley 136 are both disposed on the gate near the top of the gate, and are respectively located directly above the first fixed pulley 131 and the second fixed pulley 132; one end of the first traction rope 133 is connected to the first side of the high-pressure water gun assembly 120, and the other end passes through the first fixed pulley 131 and the first guide pulley 135 in sequence and extends to the gate platform above the gate; one end of the second traction rope 134 is connected to the second side of the high-pressure water gun assembly 120, and the other end passes through the second fixed pulley 132 and the second guide pulley 136 in sequence and extends to the gate platform above the gate.

[0025] In the specific implementation process, the lower gate section 100 is first lowered to the bottom and then raised 100-200mm to expose the working surface at the bottom of the channel. Then, the fire water valve is opened to supply water to the high-pressure water gun assembly 120. The operator pulls the first traction rope 133 and the second traction rope 134 alternately on the gate platform to drive the high-pressure water gun assembly 120 to move back and forth along the two parallel slide rails 111. The high-pressure water flow is used to flush the mud, sand, gravel and aquatic organisms deposited at the bottom of the gate channel in all directions. The dispersed debris is discharged with the water flow from the gap reserved in the gate. After the cleaning is completed, the water supply is turned off and the gate is reset to the fully closed position. The whole process can achieve efficient and safe cleaning of the bottom of the gate channel without diving.

[0026] For example, please refer to Figure 2 and Figure 3The slide rail 111 is a long strip structure, with its bottom surface fixedly connected to the gate and its top surface having an upward-opening groove along its length. The slider 112 includes a T-shaped support portion and a first track wheel 113 disposed on the support portion. The support portion includes a vertical section and a horizontal section. The vertical section is disposed within the groove, and at least two first track wheels 113 are symmetrically arranged on both sides of the bottom of the vertical section. The axle of the first track wheel 113 is perpendicular to the length direction of the slide rail 111, and the bottom of the first track wheel 113 is in rolling contact with the bottom of the groove. The horizontal section spans the opening of the groove and extends to both sides of the groove to form a support platform. The high-pressure water gun assembly 120 is disposed on the support platform of the horizontal section.

[0027] In the specific implementation process, when the operator alternately pulls the first traction rope 133 and the second traction rope 134 on the gate platform, the traction force is transmitted to the horizontal section of the slider 112 through the ropes, causing the entire slider 112 to move along the slide rail 111. During this process, the first track wheel 113 of the vertical section of the slider 112 rolls smoothly at the bottom of the chute, while the horizontal section of the T-shaped support section drives the high-pressure water gun assembly 120 to move synchronously, achieving precise positioning and stable operation. The cooperative design of the T-shaped support section and the chute in this embodiment ensures that the slider 112 can only move in a straight line along the length of the slide rail 111, avoiding deflection; the symmetrically arranged first track wheels 113 significantly reduce the movement resistance through rolling friction, making manual traction less strenuous; the support platform formed by the horizontal section provides stable support for the high-pressure water gun, effectively suppressing the vibration caused by the backflow force of the water flow; and ensuring the precise positioning of the high-pressure water gun.

[0028] For example, the slider 112 also includes a second track wheel 114 disposed on the upper part of the vertical section. The top of the second track wheel 114 rolls in contact with the inner surface of the top of the groove, and together with the first track wheel 113, forms a bidirectional limit on the upper and lower parts of the bearing portion.

[0029] In the specific implementation process, when the operator pulls the traction rope to drive the slider 112 to move, the second track wheel 114 at the top of the vertical section forms rolling contact with the inner surface of the top of the chute, and together with the first track wheel 113 at the bottom, they form a bidirectional constraint mechanism. During the movement, the first track wheel 113 bears the gravitational load of the high-pressure water gun assembly 120, while the second track wheel 114 effectively resists the upward force generated by the backflow of water. The two work together to ensure that the bearing part always stays on a stable movement trajectory. The bidirectional limiting design completely eliminates the possibility of vertical jump of the slider 112, and can maintain smooth operation even when the high-pressure water gun is operating at a high flow rate; the upper and lower track wheel sets form a torque balance to prevent the bearing part from tilting and jamming due to uneven load; the rolling contact method converts sliding friction into rolling friction, reduces traction force, improves operation convenience, and improves the movement accuracy of the device.

[0030] For example, please refer to Figure 4 The high-pressure water gun assembly 120 includes a water gun base 121 and a water gun body 122; both ends of the water gun base 121 are fixedly connected to the horizontal sections of the bearing parts of the two sliders 112 respectively; the top of the water gun base 121 is provided with a water gun mounting groove, the length direction of the water gun mounting groove is perpendicular to the length direction of the slide rail 111; the water gun body 122 is detachably disposed in the water gun mounting groove and fixed by fasteners.

[0031] In practical implementation, the high-pressure water gun assembly 120 is also equipped with a control module. This module supports wireless or wired connection and can communicate with the user's operating terminal (such as a display screen or remote control) for remote control of the water gun's start / stop and operating mode adjustment. When it is necessary to replace or maintain the water gun body 122, the operator only needs to loosen the fasteners to remove the water gun body 122 from the water gun mounting slot; during installation, the water gun body 122 is aligned with the mounting slot and placed in, and then the fasteners are tightened to complete the fixation. The guide positioning design of the water gun mounting slot ensures accurate resetting every time it is installed, maintaining a consistent spray angle and improving maintenance convenience.

[0032] For example, the water gun holder 121 includes a base plate, a mounting block, and a locking member; the mounting block is rotatably connected to the base plate via a rotating shaft, and the mounting block is provided with the water gun mounting groove; the mounting block is provided with a plurality of first positioning holes arranged in a circular array around the rotating shaft; the base plate is provided with a plurality of second positioning holes arranged in a circular array around the rotating shaft; the locking member is detachably inserted into the corresponding first positioning hole and second positioning hole to lock the relative rotation angle between the mounting block and the base plate.

[0033] In practical implementation, when adjusting the water gun spray angle, first loosen the locking device, allowing the mounting block to rotate freely around the axis. The operator rotates the mounting block to the desired angle, aligning the first positioning hole on the mounting block with the corresponding second positioning hole on the base plate, and then inserts the locking device to complete the fixation. The circumferential array of positioning holes allows for precise multi-level adjustment to meet the flushing needs of different working conditions. The axis structure ensures smooth and stable angle adjustment while maintaining the centered positioning of the water gun body 122. The pin-type locking device is simple and reliable to operate, with excellent vibration resistance. Multi-angle adjustment optimizes the flushing effect for different sediment characteristics, improving cleaning efficiency. This enhances the device's adaptability and operational flexibility.

[0034] Exemplarily, the combined height H of the slide rail 111, the slider 112 and the high-pressure water gun assembly 120, and the height H1' of the first fixed pulley 131 and the height H2' of the second fixed pulley 132 of the traction assembly 130 are all less than the protruding height h of the gate peripheral sealant 101, that is, it satisfies: H < h, H1' < h, and H2' < h; where: the combined height H is the vertical distance from the bottom surface of the slide rail 111 to the highest point of the high-pressure water gun assembly 120; the height H1' of the first fixed pulley 131 is the vertical distance from the bottom surface of the first fixed pulley 131 to its highest point; the height H2' of the second fixed pulley 132 is the vertical distance from the bottom surface of the second fixed pulley 132 to its highest point.

[0035] By strictly controlling the combined height H of the slide rail 111 - slider 112 - water gun assembly and the heights H1' and H2' of the two fixed pulleys, it is ensured that all moving parts are lower than the protruding height h of the gate peripheral sealant 101 (i.e., H < h, H1' < h, H2' < h), effectively preventing interference problems - when the gate is fully closed, all working parts can be completely accommodated within the protection range of the sealant 101, avoiding mechanical collisions with the door frame; and ensuring that the compression deformation space of the sealant 101 will not be damaged during the operation of the device, maintaining the watertightness of the gate; enabling the device to operate safely throughout the full stroke of the gate.

[0036] Exemplarily, the slide rail 111, the slider 112, the high-pressure water gun assembly 120, the first fixed pulley 131 and the second fixed pulley 132 are all made of stainless steel.

[0037] The excellent corrosion resistance of stainless steel can resist water flow erosion and biological attachment for a long time, keeping the structural integrity of the equipment in a humid environment; its high hardness characteristic can effectively reduce the wear rate of key moving parts, greatly extending the service life; the smooth surface characteristic ensures that the friction coefficient of the track system is stable within a small range, ensuring the smoothness of the traction operation; and at the same time completely avoiding the pollution of the water body by the anti-rust coating, meeting the environmental protection requirements.

[0038] Exemplarily, the first traction rope 133 includes one of a thin steel wire rope or a nylon rope; the second traction rope 134 includes one of a thin steel wire rope or a nylon rope.

[0039] The thin steel wire rope has extremely high tensile strength and excellent wear resistance; the nylon rope has the characteristics of light weight and flexibility, making the pulling operation of the operator on the gate platform more labor-saving. Its unique elastic deformation ability can buffer the impact load when the high-pressure water gun starts suddenly and will not cause metal corrosion problems. In practical applications, it can be selected according to the specific working conditions: when cleaning the gate slot with heavy deposits and hard debris, a steel wire rope is preferably used, while in the case of routine maintenance or frequent operations, a nylon rope can be selected.

[0040] For example, the first fixed pulley 135 includes: a first semi-enclosed pulley seat, including a first rear wall, a first front wall, a first side wall, and a first bottom wall, the first rear wall being fixedly connected to the gate; a first pulley body, rotatably disposed between the first rear wall and the first front wall via a first rotating shaft, its axis being perpendicular to the gate plane; wherein, the first front wall includes a first rotating shaft mounting part and a first L-shaped anti-detachment guard part; the second fixed pulley 136 includes: a second semi-enclosed pulley seat, including a second rear wall, a second front wall, a second side wall, and a second bottom wall, the second rear wall being fixedly connected to the gate; a second pulley body, rotatably disposed between the second rear wall and the second front wall via a second rotating shaft, its axis being perpendicular to the gate plane; wherein, the second front wall includes a second rotating shaft mounting part and a second L-shaped anti-detachment guard part.

[0041] In practical implementation, when the first traction rope 133 passes around the first pulley body, the first side wall restricts the rope's lateral leftward deviation, the first bottom wall prevents the first traction rope 133 from sagging and falling off, and the first L-shaped guard prevents the first traction rope 133 from detaching forward, forming a three-dimensional protective structure. When the second traction rope 134 passes around the second pulley body, the second side wall restricts the rope's lateral rightward deviation, the second bottom wall prevents the second traction rope 134 from sagging and falling off, and the second L-shaped guard prevents the second traction rope 134 from detaching forward, forming a three-dimensional protective structure. The integrated L-shaped guard achieves multi-directional limiting, ensuring both reliable protection and sufficient operating space for maintenance. The coordinated action of the pulley seat's various walls dynamically adapts to the swaying of the traction rope during high-speed movement, effectively reducing the risk of rope detachment.

[0042] In summary, the gate bottom groove debris removal device of this embodiment includes two parallel slide rails 111 arranged at the bottom of the gate, two sliders 112 slidably arranged on the slide rails 111, a high-pressure water gun assembly 120 mounted on the sliders 112, and a traction assembly 130. The traction assembly 130 includes fixed pulleys at both ends of the slide rails 111 and a traction rope passing over the fixed pulleys. The traction rope controls the sliders 112 to move the high-pressure water gun along the slide rails 111. This gate bottom groove debris removal device removes debris from the bottom of the gate groove by spraying water with a high-pressure water gun, achieving rapid cleaning without diving operations, resulting in high efficiency and good safety. The slide rail 111 and slider 112 mechanism, combined with the fixed pulley traction system, ensures smooth and reliable water gun operation. The overall structure is simple and compact, facilitating installation and maintenance.
