Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction equipment technology, and in particular to a water-blocking device for channel construction. Background Technology

[0002] In water conservancy projects, when maintaining, repairing or building new channels, it is often necessary to temporarily block the water flow in the construction area to create a dry construction environment. Traditional water-blocking devices usually use simple earthen cofferdams or fixed-size baffles, but these methods have many inconveniences in practical applications.

[0003] First, simple earthwork cofferdams are not only time-consuming and labor-intensive to construct, but also have a significant impact on the environment. When dismantling them, they generate a large amount of silt, increasing cleanup costs and environmental burden. While using fixed-size baffles can solve the drawbacks of earthwork cofferdams to some extent, they have poor versatility. For canals of different widths and water depths, different baffles need to be customized or complex on-site modifications need to be made, which increases construction costs and time and reduces construction efficiency.

[0004] The stability of existing water-blocking equipment after blocking water flow is an urgent problem to be solved. The huge thrust of the water may cause the baffle to overturn or shift, resulting in the construction area being flooded again. This not only delays the construction period but also poses safety hazards. The lack of an effective stabilizing structure makes the equipment unreliable under complex water conditions.

[0005] Therefore, this utility model proposes a water-blocking device for channel construction to overcome the shortcomings of the prior art. Utility Model Content

[0007] This utility model provides a channel construction water-blocking device, including: a plate body, a base plate, a support plate, an adjustment mechanism, and a drainage mechanism.

[0008] The adjustment mechanism includes an adjustment plate, a slide rail, a ratchet, and a control component. The adjustment plate is slidably disposed inside both sides of the plate body. The slide rail is disposed inside the plate body and slides with the adjustment plate to provide guidance. The ratchet is fixed to the top of the adjustment plate. The control component engages with the ratchet to lock the position of the adjustment plate.

[0009] The drainage mechanism includes a drainage window, a gate, a slide rail 2, a connecting rod, and a drive assembly. The drainage window is located in the lower middle part of the plate. The gate is slidably installed inside the middle of the plate and cooperates with the drainage window to control the opening size of the drainage window. The slide rail 2 is installed inside the plate and cooperates with the gate to ensure the stability of the gate's movement path. The connecting rod connects the top of the gate to the drive assembly.

[0010] Furthermore, the base plate is fixed to the bottom of the plate body, the support plate is installed on the rear side of the plate body, the adjustment mechanism is installed on both sides of the plate body, and the drainage mechanism is installed in the lower middle part of the plate body. The above components are connected and cooperate with each other to form a complete channel construction water-blocking device.

[0011] Preferably, the control assembly includes a pawl, a locking pin, a limiting ring, and a disc spring. The pawl is rotatably disposed in a groove at the top of the plate and forms a one-way engagement structure with the ratchet. The locking pin can be pulled upward to push the pawl out of the ratchet's engagement state. The limiting ring is fixed to the outer wall of the locking pin.

[0022] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0023] Example: Please refer to Figure 1 A channel construction water-blocking device includes a plate body 1, which serves as the core carrier and main body of the entire water-blocking device, used to block water flow; a base plate 4 is fixedly connected to the bottom of the plate body 1, extending forward to contact the water body, used to maintain the stability of the plate body 1 under the weight of the blocked water body, the base plate 4 uses the weight of the blocked water body to maintain the stability of the plate body 1, this design uses the weight of the water body to provide stability, and the structure is reliable; a support plate 5 is installed on the rear side of the plate body 1, the support plate 5 is a triangular structure, installed on the rear side of the plate body 1, used to provide support from behind, multiple support plates 5 provide additional support force to the plate body 1 from behind, working together with the base plate 4 to further enhance the overall anti-overturning ability and structural stability.

[0024] like Figure 1 , Figure 2 and Figure 4As shown, the adjusting mechanism 2 and the drainage mechanism 3 are both integrated on the plate body 1. The adjusting mechanism 2 is installed on both sides of the plate body 1. The adjusting mechanism 2 is used to adjust the water blocking range according to the width of the water channel, enhancing the adaptability to water channels of different specifications. The adjusting mechanism 2 achieves the width change through a telescopic structure. The drainage mechanism 3 is installed in the middle and lower part of the plate body 1. The drainage mechanism 3 is used to open a drainage port on the plate body 1, control the water volume in the plate body 1, and help drain water during disassembly, improving the convenience of disassembly. The drainage mechanism 3 achieves the control of drainage volume through an openable and closable structure. The plate body 1 provides the installation foundation and accommodation space for the telescopic movement of the adjusting mechanism 2 and the opening and closing of the drainage mechanism 3.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The adjusting mechanism 2 includes an adjusting plate 201, a slide rail 202, a ratchet rack 203, and a control component 204. The adjusting plate 201 is slidably disposed inside both sides of the plate body 1, allowing the water-blocking range to be flexibly adjusted according to the actual channel width. The slide rail 202 is disposed inside the plate body 1 and slides in cooperation with the adjusting plate 201. The slide rail 202 provides precise guidance for the adjusting plate 201 and prevents the adjusting plate 201 from falling out of the plate body 1, ensuring the stability and reliability of the adjusting plate 201 during the extension and retraction process. The ratchet rack 203 is fixed to the top of the adjusting plate 201 and has a series of serrated structures for engaging with the pawl 2041 in the control component 204 to achieve precise positioning and locking. The control component 204 engages with the ratchet rack 203 to lock the position of the adjusting plate 201.

[0026] The control assembly 204 includes a pawl 2041, a locking pin 2042, a limiting ring 2043, and a disc spring 2044. The pawl 2041 is rotatably disposed in a groove at the top of the plate 1. The lower end of the pawl 2041 engages with the teeth of the ratchet rack 203 to form a one-way locking structure, which is used to prevent the adjusting plate 201 from automatically retracting when it is pulled outward. The locking pin 2042 can be pulled upward, and the upper part of the locking pin 2042 contacts the rear part of the pawl 2041. When the locking pin 2042 is pulled, it can push the pawl 2041 to disengage from the ratchet rack 203. The adjustment plate 201 is unlocked and can be freely retracted when engaged. The limiting ring 2043 is fixed to the outer wall of the locking pin 2042 and is used to limit the pulling stroke of the locking pin 2042. The disc spring 2044 is filled between the limiting ring 2043 and the inner wall of the plate body 1. The disc spring 2044 provides downward elastic force to make the locking pin 2042 automatically reset after being released, thereby pushing the pawl 2041 to re-engage on the ratchet rack 203 and restore the locking function. This structure ensures the stability of the positioning of the adjustment plate 201 and the convenience of operation.

[0027] The drainage mechanism 3 includes a drainage window 301, a gate 302, a second slide rail 303, a connecting rod 304, and a drive assembly 305. The drainage window 301 is located in the lower middle part of the plate body 1, serving as an outlet for the water inside the water-blocking area. The gate 302 is slidably disposed inside the middle end of the plate body 1. The gate 302 cooperates with the drainage window 301 to control the opening size of the drainage window 301, thereby adjusting the drainage volume. The second slide rail 303 is disposed inside the plate body 1 and slides in cooperation with the gate 302. The second slide rail 303 provides precise vertical movement guidance for the gate 302 to ensure the stability of the gate 302's movement path and prevent jamming. The connecting rod 304 connects the top of the gate 302 to the drive assembly 305. The connecting rod 304 transmits power from the drive assembly 305, driving the gate 302 to move up and down.

[0028] In a preferred embodiment, the drive assembly 305 includes a housing 3051 and a hydraulic push rod 3052. The moving piston rod of the hydraulic push rod 3052 is directly connected to the connecting rod 304 to drive the gate 302 to move up and down. The housing 3051 is sleeved on the outside of the hydraulic push rod 3052 and fixed to the top surface of the plate 1. The housing 3051 is used to fix and protect the hydraulic push rod 3052. As a reliable and precisely controlled drive method, the hydraulic push rod 3052 ensures that the gate 302 opens and closes smoothly and powerfully. The housing 3051 provides necessary physical protection for the hydraulic push rod 3052, extends the service life of the equipment, and reduces maintenance costs.

[0029] As another preferred embodiment, the pawl 2041 and the ratchet rack 203 in the control component 204 form a one-way meshing structure. This structure is used to prevent the adjusting plate 201 from automatically retracting when it is pulled outward, ensuring that the adjusting plate 201 is firmly locked in the extended state. This avoids the adjusting plate 201 from accidentally retracting under water flow impact or external interference, thereby affecting the water blocking effect. This one-way locking mechanism improves the stability and safety of equipment operation.

[0030] In another preferred embodiment, the disc spring 2044 in the control assembly 204 is filled between the limiting ring 2043 and the inner wall of the plate body 1. The disc spring 2044 is used to reset the locking pin 2042 after it is pulled. When the operator pulls the locking pin 2042 upward to unlock the adjusting plate 201, the elasticity of the disc spring 2044 can automatically push the locking pin 2042 back to its original position, so that the pawl 2041 re-engages with the ratchet rack 203 and restores the locked state. This automatic reset function simplifies the operation steps, improves the ease of use of the equipment, and prevents potential safety hazards caused by forgetting to reset.

[0031] As another preferred embodiment, the cooperation between the adjusting plate 201 and the slide rail 202, and the cooperation between the gate 302 and the slide rail 303, are all sliding cooperation. This sliding cooperation ensures the smooth extension and retraction of the adjusting plate 201 in the horizontal direction and the smooth opening and closing of the gate 302 in the vertical direction. It effectively reduces the frictional resistance during the movement process, improves the operating efficiency and service life of the components, and the sliding cooperation structure is simple and reliable, easy to manufacture and maintain, and is the preferred solution for realizing the relative movement of components.

[0032] Working principle: The base plate 4 is located at the bottom of the plate body 1, using the gravity of the blocked water to maintain the stability of the plate body 1. Multiple triangular support plates 5 are installed on the rear side of the plate body 1, providing support from behind. The adjustment mechanism 2 can adjust the water-blocking range according to the width of the water channel, enhancing adaptability to water channels of different specifications. The adjustment plate 201 slides inside the sides of the plate body 1, with the slide rail 202 acting as a guide and preventing the adjustment plate 201 from falling out of the plate body 1. The sealing strip 205 is located at the joint between the adjustment plate 201 and the plate body 1 to ensure water tightness. A ratchet rack 203 is fixed to the top of the adjustment plate 201, which is controlled by... The control component 204 is used for position locking. The pawl 2041 rotates in the groove at the top of the plate body 1 and engages with the ratchet rack 203. When the adjustment plate 201 is pulled out, it can prevent the adjustment plate 201 from retracting. When the adjustment plate 201 needs to be stored inside the plate body 1, the locking pin 2042 is pulled upward. The outer wall of the locking pin 2042 is fixed with a limit ring 2043. A disc spring 2044 is filled between the limit ring 2043 and the inner wall of the plate body 1, so that the locking pin 2042 can be reset after being pulled, thereby causing the locking pin 2042 to push the pawl 2041 to engage with the ratchet rack 203. The drainage mechanism 3 can open a drainage port on the plate body 1 to control the water volume inside the plate body 1. At the same time, it can help drain water during disassembly and improve the convenience of disassembly. The drainage window 301 is opened in the lower middle part of the plate body 1. The gate 302 slides up and down inside the middle of the plate body 1 to control the opening size of the drainage window 301 and thus control the drainage volume. The gate 302 slides up and down inside the plate body 1 through the slide rail 303 to ensure the stability of the movement path. The top of the gate 302 is connected to the drive assembly 305 by the connecting rod 304. The drive assembly 305 provides power for the opening and closing of the gate 302. The moving piston rod of the hydraulic push rod 3052 is directly connected to the connecting rod 304 to drive the gate 302 to move up and down. The outer shell 3051 is sleeved on the outside of the hydraulic push rod 3052 and fixed to the top surface of the plate body 1 to fix and protect the hydraulic push rod 3052.
