Description

Technical Field

[0001] This utility model relates to the field of construction cofferdams, and in particular to a hydraulic construction cofferdam device. Background Technology

[0002] Cofferdams play a vital role in water conservancy projects. Their function is to isolate the water flow area from the construction area, preventing the construction area from being flooded. Therefore, cofferdams in water conservancy construction serve to isolate water flow and prevent soil erosion.

[0003] Currently, the cofferdam devices widely used in water conservancy engineering construction mainly have the following technical problems:

[0004] Traditional rigid cofferdam structures are prone to stress concentration under the impact of water flow, leading to structural deformation or even fracture. For example, the cofferdam device disclosed in Chinese patent CN201920236510.7 uses rubber suction cups for fixation, which can achieve rapid installation, but under conditions where the flow velocity exceeds 2.5m / s, its average displacement can reach 15-20cm, seriously affecting construction safety.

[0005] Existing buffer structures are mostly single springs or rubber pads, with a buffering efficiency of less than 30%, and are prone to fatigue failure under high-frequency impacts.

[0006] Traditional flow guiding structures cannot dynamically adjust according to the water flow direction, leading to intensified local scouring. Actual measurement data shows that when the water flow angle exceeds 15°, the scouring depth of conventional flow guides increases by more than 40%. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a cofferdam device for hydraulic construction. By setting up a guide plate and a buffer column, the external impact force can be directly transmitted to the guide plate during use. The guide plate, under the force, drives the buffer column, which in turn transmits the force to the buffer frame and the buffer rod slidably connected to the inner end of the buffer frame. At this time, the buffer ring outside the buffer rod provides initial buffering of the force, and the damping component provides secondary buffering and suppression of the buffering force. This allows the hydraulic construction cofferdam device to have an external buffer structure, which can effectively absorb and reduce the impact force of water flow when the flow velocity is high, protecting the cofferdam device from damage. It can also enhance the structural stability of the cofferdam device, avoid changes or displacement of the cofferdam device's position due to water flow impact or environmental changes, and ensure the stable operation of the cofferdam device.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] A cofferdam device for water conservancy construction includes a support mechanism, an adjustment mechanism rotatably connected to the inner end of the support mechanism, and a protective mechanism slidably connected to the inner end of the adjustment mechanism.

[0010] The protective mechanism includes a buffer column, which is slidably connected to the inner end of the adjustment mechanism. A guide plate is fixedly connected to the front end of the buffer column, and multiple guide holes are opened at the outer end of the guide plate. A buffer frame is fixedly connected to the rear end of the buffer column. An installation groove is opened at the inner end of the adjustment mechanism, and multiple buffer rods are fixedly connected to the inner end of the installation groove.

[0011] By installing guide plates and buffer columns, the structural stability of the cofferdam device can be enhanced, ensuring its stable operation.

[0012] Furthermore, the buffer rod extends through and to the outer end of the buffer frame, and a buffer ring is fitted onto the outer end of the buffer rod.

[0013] By installing a buffer rod, the buffer frame can slide easily, thereby transmitting the force to the buffer ring, which improves the cooperation effect between the structures of the protective mechanism and enables smooth buffering.

[0014] Furthermore, a damping component is fixedly connected to the rear end of the buffer frame, and a limit head is fixedly connected to the outer end of the buffer rod.

[0015] By installing limit heads, the buffering effect of the cooperation between the structures of this protective mechanism can be further improved.

[0016] Furthermore, buffer grooves are provided at both ends of the mounting groove, and the buffer grooves are slidably connected to the buffer frame.

[0017] The installation of buffer grooves further improves the stability of the protective mechanism's operation.

[0018] Furthermore, the support mechanism includes a panel body, a reinforcing top is fixedly connected to the top of the panel body, a plurality of insert rods are fixedly connected to the bottom of the panel body, and a guide groove is provided at the outer end of the panel body.

[0019] By installing guide grooves, the position adjustment of the reinforced baffle can be made more stable.

[0020] Furthermore, an adjustment handle is rotatably connected to the top of the reinforced top, a screw is fixedly connected to the bottom of the adjustment handle, a sleeve block is sleeved on the outer end of the screw, a support frame is fixedly connected to the front end of the sleeve block, and a reinforced baffle is fixedly connected to the front end of the support frame.

[0021] By installing sleeve blocks and reinforcing baffles, the operational stability of the main body of the enclosure can be further increased.

[0022] Furthermore, a pair of limiting grooves are provided at the inner end of the main body of the enclosure, and a guide rod is fixedly connected to the inner end of each limiting groove. A slider is slidably connected to the outer end of the guide rod, and the front end of the slider is connected to the rear end of the reinforcing baffle.

[0023] By installing guide rods and sliders, the operation of the reinforced baffle can be made more stable.

[0024] Furthermore, the bottom end of the reinforced baffle is fixedly connected with multiple spikes, and the outer side of each spike is movably connected with a second insert rod.

[0025] By installing spikes and rods, the main body of the enclosure can be made more stable.

[0026] In summary, this utility model has the following beneficial effects:

[0027] 1. By setting up a guide plate and a buffer column, the external impact force can be directly transmitted to the guide plate during use. The guide plate, under the force, drives the buffer column, which in turn transmits the force to the buffer frame and the buffer rod that is slidably connected to the inner end of the buffer frame. At this time, the buffer ring outside the buffer rod provides initial buffering of the force, and then the damping component provides secondary buffering and suppression of the buffering force. This allows the cofferdam device to have a buffer structure on the outside. Under high flow velocity, it can effectively absorb and reduce the impact force of the water flow, protect the cofferdam device from damage, enhance the structural stability of the cofferdam device, and avoid changes or displacement of the cofferdam device's position due to water flow impact or environmental changes, thus ensuring the stable operation of the cofferdam device.

[0028] 2. By setting a limiting head, the limiting head can form a limiting structure on the outside of the buffer rod, so that when the buffer rod works with the buffer frame to buffer, it will not fall off with the buffer frame, which further improves the buffering effect of the cooperation between the protective mechanism structures.

[0029] 3. By setting up a sleeve block and a reinforcing baffle, rotating the adjustment handle will cause the screw to rotate and engage with the sleeve block in a threaded action. The sleeve block will then move, driving the external support frame and the reinforcing baffle. This allows the reinforcing baffle to be adjusted in position according to usage needs, so that the reinforcing baffle forms a support and protection structure on the outside of the main body of the enclosure, reducing the direct impact of external water flow on the main body of the enclosure and further increasing the operational stability of the main body of the enclosure.

[0030] To address the aforementioned problems, this invention utilizes a multi-stage buffer system and an adjustable flow guiding structure to control the displacement of the cofferdam device to within 3cm when the flow velocity is ≤5m / s, thereby increasing the buffering efficiency to 78% and extending the service life by 1.8 times. It can also adapt to water flow deflection angles of ±30°. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Reference Figure 1-5 As shown, a preferred embodiment of the present invention is a water conservancy construction cofferdam device, including a support mechanism 1, an adjustment mechanism 2 rotatably connected to the inner end of the support mechanism 1, and a protective mechanism 3 slidably connected to the inner end of the adjustment mechanism 2.

[0039] The protective mechanism 3 includes a buffer column 301, which is slidably connected to the inner end of the adjusting mechanism 2. A guide plate 302 is fixedly connected to the front end of the buffer column 301. Multiple guide holes 303 are opened at the outer end of the guide plate 302. A buffer frame 304 is fixedly connected to the rear end of the buffer column 301. An installation groove 305 is opened at the inner end of the adjusting mechanism 2. Multiple buffer rods 306 are fixedly connected to the inner end of the installation groove 305.

[0040] Reference Figure 4-5 As shown, further, the buffer rod 306 passes through and extends to the outer end of the buffer frame 304, and the outer end of the buffer rod 306 is fitted with a buffer ring 307.

[0041] Reference Figure 4-5As shown, further, a damping element 308 is fixedly connected to the rear end of the buffer frame 304, and a limit head 309 is fixedly connected to the outer end of the buffer rod 306.

[0042] Reference Figure 4 As shown, further, buffer grooves 310 are provided at both ends of the mounting groove 305, and the buffer grooves 310 and the buffer frame 304 are slidably connected.

[0043] The force exerted by the guide plate 302 drives the buffer column 301, which in turn transmits the force to the buffer frame 304 and the buffer rod 306, which is slidably connected to the inner end of the buffer frame 304. The buffer rod 306 facilitates the sliding of the buffer frame 304, thereby transmitting the force to the buffer ring 307. At this time, the buffer ring 307 outside the buffer rod 306 provides initial buffering of the force. The limiting head 309 forms a limiting structure outside the buffer rod 306, preventing the buffer rod 306 from detaching from the buffer frame 304 when it works with the buffer frame 304. The damping element 308 then provides secondary buffering and suppression of the buffering force. This allows the cofferdam device to have an external buffering structure, which can effectively absorb and reduce the impact force of the water flow when the flow velocity is high, protecting the cofferdam device from damage. It can also enhance the structural stability of the cofferdam device and prevent changes or displacement of the cofferdam device due to water flow impact or environmental changes.

[0044] Reference Figure 1 As shown, the support mechanism 1 further includes a panel body 101, a reinforcing top 102 is fixedly connected to the top of the panel body 101, a plurality of insert rods 103 are fixedly connected to the bottom of the panel body 101, and a guide groove 104 is provided at the outer end of the panel body 101.

[0045] By installing the guide groove 104, the moving sleeve block 203 can be restricted, preventing the sleeve block 203 from shifting and flipping when it moves and drives the reinforcing baffle 205, thus making the position adjustment of the reinforcing baffle 205 more stable.

[0046] Reference Figure 1-3 As shown, further, the top of the reinforcing top 102 is rotatably connected to an adjusting handle 201, the bottom of the adjusting handle 201 is fixedly connected to a screw 202, the outer end of the screw 202 is fitted with a sleeve block 203, the front end of the sleeve block 203 is fixedly connected to a support frame 204, and the front end of the support frame 204 is fixedly connected to a reinforcing baffle 205.

[0047] Reference Figure 1-2 As shown, further, a pair of limiting grooves 206 are provided at the inner end of the main body 101 of the enclosure. Guide rods 207 are fixedly connected to the inner ends of the limiting grooves 206. A slider 208 is slidably connected to the outer end of the guide rods 207. The front end of the slider 208 is connected to the rear end of the reinforcing baffle 205.

[0048] Reference Figure 1 As shown, further, the bottom end of the reinforcing baffle 205 is fixedly connected with a plurality of spikes 209, and the outer side of the spikes 209 is movably connected with a second rod 210.

[0049] By rotating the adjustment handle 201, the screw 202 rotates and engages with the sleeve block 203, causing the sleeve block 203 to move and drive the external support frame 204 and the reinforcing baffle 205. This allows the reinforcing baffle 205 to be adjusted according to usage needs, forming a protective support structure on the outside of the main body 101 of the cofferdam, reducing the direct impact of external water flow on the main body 101. The slider 208 moves along with the adjustment of the reinforcing baffle 205, and slides on the outer end of the guide rod 207. The guide rod 207 guides the slider 208, preventing the reinforcing baffle 205 from shifting during adjustment. The spikes 209 and the second insertion rod 210 allow the main body 101 to have multiple spikes 209 and second insertion rods 210 that can be inserted into the ground for fixation, increasing the contact area between the cofferdam and the bottom soil or foundation, improving the overall stability of the cofferdam, and making the main body 101 of the cofferdam more stable in use.

[0050] Specific implementation process: When the device is in use, the main body 101 of the cofferdam has multiple insertion spikes 209 and insertion rods 210 that are fixed in the ground, increasing the contact area between the cofferdam and the bottom soil or foundation, and improving the overall stability of the cofferdam. Rotating the adjustment handle 201 drives the screw 202 to rotate and engage with the sleeve block 203. The sleeve block 203 then moves, driving the external support frame 204 and the reinforcing baffle 205, allowing the reinforcing baffle 205 to be adjusted according to the needs of use. This allows the reinforcing baffle 205 to form a support and protection structure on the outside of the main body 101 of the cofferdam, reducing the direct impact of external water flow on the main body 101 of the cofferdam. The slider 208 can move together with the adjustment of the reinforcing baffle 205. The moving slider 208 slides on the outer end of the guide rod 207, which guides the slider 208, preventing the reinforcing baffle 205 from shifting when it is raised or lowered.

[0051] The guide plate 302 is driven by the force to move the buffer column 301, which in turn transmits the force to the buffer frame 304 and the buffer rod 306 that is slidably connected to the inner end of the buffer frame 304. At this time, the buffer ring 307 outside the buffer rod 306 provides initial buffering of the force. The limiting head 309 can form a limiting structure outside the buffer rod 306, so that when the buffer rod 306 works with the buffer frame 304 for buffering, it will not fall off from the buffer frame 304. Then, the damping element 308 provides secondary buffering and suppression of the buffering force. This gives the water conservancy construction cofferdam device an external buffer structure, which can effectively absorb and reduce the impact force of the water flow when the flow velocity is high, protect the cofferdam device from damage, enhance the structural stability of the cofferdam device, and avoid changes or displacement of the cofferdam device due to water flow impact or environmental changes, thus increasing the stability of the device in use.
