Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy construction, and more specifically, to a water conservancy construction closure device and a closure method. Background Art

[0002] In water conservancy project construction, closure is a key link in the construction. Its purpose is to cut off the natural water flow so as to carry out the construction of hydraulic structures under the condition of a dry riverbed. Traditional closure methods usually require a large amount of manpower, material resources and time, and are greatly affected by hydrological conditions, with relatively high construction risks.

[0003] The existing closure devices have the following deficiencies:

[0004] Low positioning accuracy: During the positioning process of traditional closure devices, it is difficult to accurately control the position and verticality of the device, which easily leads to poor closure effects.

[0005] Low construction efficiency: The installation, debugging and removal processes of the closure device are cumbersome, requiring a large amount of time and manpower, which affects the progress of the entire project.

[0006] Low reuse rate: Some closure devices are difficult to recycle and reuse after use, resulting in a waste of resources.

[0007] Therefore, how to provide a water conservancy construction closure device and a closure method that can improve the efficiency, safety and economy of closure construction is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0008] In view of this, the present invention provides a water conservancy construction closure device and a closure method.

[0009] To achieve the above object, the present invention provides the following technical solutions, mainly including: a main frame, an adjustment mechanism, a telescopic gate, and a positioning pile mechanism;

[0010] The adjustment mechanism is fixedly arranged at the top of the main frame, the telescopic gate is installed below the main frame, and the positioning pile mechanism is fixedly installed at the bottom of the main frame.

[0011] Preferably, the main frame includes an I-shaped connecting frame horizontally placed at the top, a support platform horizontally extending from one side of the connecting frame, and a stable base horizontally extending at the bottom.

[0012] Preferably, the adjusting mechanism includes a driving motor mechanism fixedly connected to the central area of the above-mentioned support platform, a screw mechanism fixedly connected to the output shaft of the driving motor mechanism, a nut mechanism nested on the screw mechanism through thread fit, a connecting column horizontally and fixedly connected to the nut mechanism, and a transverse connecting column vertically and fixedly connected to the connecting column. Lifting columns are symmetrically arranged at both ends of the transverse connecting column, and the lifting columns are respectively nested into two groups of positioning and supporting mechanisms. The two groups of positioning and supporting mechanisms are fixed on an I-shaped connecting frame horizontally placed on the top through flanges.

[0013] Preferably, bolt hole positions are opened at the lower ends of the lifting columns in the adjusting mechanism, and bolt hole positions are correspondingly opened at the top ends of the telescopic gate. The lifting columns are fixedly connected to the telescopic gate through bolts.

[0014] Preferably, the positioning pile mechanism includes a positioning sleeve fixedly connected to the stable base through a flange, a directional column nested inside the positioning sleeve, and a limiting column horizontally arranged at a certain height of the directional column.

[0015] Preferably, the intercepting method of the water conservancy construction intercepting device includes the following steps:

[0016] S1. Device transportation and installation: Before the water conservancy construction interception, the adjusting mechanism, the telescopic gate and the positioning pile mechanism are sequentially installed on the main frame and debugged to ensure the normal operation of each mechanism;

[0017] S2. Driving the positioning piles: Drive the directional column into the riverbed to a certain depth (generally 5 - 8 meters) through the positioning sleeve and the stable base;

[0018] S3. Lifting control of the telescopic gate: Start the driving motor mechanism. The motor drives the screw mechanism to rotate through the reducer. Since the nut mechanism and the screw mechanism are in thread fit, and a guiding key is arranged on the outer side of the nut mechanism, the nut mechanism moves linearly along the screw mechanism, driving the connecting column, the transverse connecting column and the lifting column to rise and fall together. The lifting column is fixedly connected to the telescopic gate through bolts, so as to realize the lifting control of the telescopic gate 300;

[0019] S4. Interception process: When interception is required, start the driving motor mechanism to raise the telescopic gate to the top of the river bank to form a complete interception surface;

[0020] S5. Device removal: Pull out the directional column from the riverbed through the limiting column. Finally, remove each component of the intercepting device in sequence.

[0021] As can be seen from the above technical solutions, compared with the prior art, the present invention has the following remarkable advantages: Through the positioning pile mechanism, the position and verticality of the device can be accurately controlled, ensuring that the intercepting device is accurately installed at the predetermined position. The efficient lifting and adjusting mechanism: The adjusting mechanism adopts the screw-nut transmission method, which has the advantages of high transmission efficiency, high positioning accuracy, and large load-bearing capacity, and can achieve precise lifting control of the telescopic gate. By the forward and reverse rotation of the driving motor mechanism 201, the telescopic gate can be quickly raised and lowered, greatly improving the construction efficiency. In addition, the main frame, the adjusting mechanism, the telescopic gate, and the positioning pile mechanism all adopt modular design, which is convenient for transportation, installation, and disassembly. Reusable: The intercepting device of the present invention has a solid structure and a long service life. After the construction is completed, it can be conveniently removed and recycled, with a high reuse rate, reducing the project cost. The orientation column in the positioning pile mechanism can be easily pulled out through the limit column, without causing permanent damage to the riverbed, meeting the environmental protection requirements.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] A water conservancy construction intercepting device disclosed by the present invention includes: a main frame 100, an adjusting mechanism 200, a telescopic gate 300, and a positioning pile mechanism 400;

[0029] AsFigure 1 As shown in the figure, an adjusting mechanism 200 is fixedly arranged at the top of the main frame 100. An expansion gate 300 is installed below the main frame 100, and a positioning pile mechanism 400 is fixedly installed at the bottom of the main frame 100.

[0030] The main frame 100 includes an I-shaped connecting frame 102 horizontally placed at the top, a support platform 101 horizontally extending from one side of the connecting frame 102, and a stable base 103 horizontally extending at the bottom.

[0031] As Figure 1 , Figure 2 shown, the adjusting mechanism 200 includes a driving motor mechanism 201 fixedly connected to the central area of the above-mentioned support platform 101, a screw mechanism 202 fixedly connected to the output shaft of the driving motor mechanism 201, a nut mechanism 203 nested on the screw mechanism 202 through thread fit, a connecting column 204 horizontally and fixedly connected to the nut mechanism, a transverse connecting column 205 vertically and fixedly connected to the connecting column 204. Lifting columns 207 are symmetrically arranged at both ends of the transverse connecting column 205. The lifting columns 207 are respectively nested into two groups of positioning and supporting mechanisms 206, and the two groups of positioning and supporting mechanisms 206 are fixedly installed on the I-shaped connecting frame 102 horizontally placed at the top through flanges.

[0032] A bolt hole position is opened at the lower end of the lifting column 207 in the adjusting mechanism 200, and a corresponding bolt hole position is opened at the top end of the expansion gate 300. The lifting column 207 is fixedly connected to the expansion gate 300 through bolts.

[0033] As Figure 1 , Figure 4 shown, the positioning pile mechanism 400 includes a positioning sleeve 403 fixedly connected to the stable base 103 through a flange, a guiding column 401 nested inside the positioning sleeve 403, and a limiting column 402 horizontally placed at a certain height of the guiding column 401. The guiding column 401 penetrates through the positioning sleeve 403 and the stable base 103 until it is driven into the riverbed to a certain depth. The limiting column 402 horizontally placed at a certain height of the guiding column 401 can set the installation height according to the depth of driving into the riverbed, and is used to pull out the positioning column 401 after the later construction is completed.

[0034] To further optimize the above technical solution, the main frame 100, as the support structure of the entire device, is made of high-strength alloy steel and specifically includes: an I-shaped connecting frame 102 horizontally placed at the top, which is used to support the adjustment mechanism 200 and transfer loads; a support platform 101 horizontally extending from one side of the connecting frame 102 and welded with a steel plate of δ = 20 mm, which is used to install the drive motor mechanism 201 and provide an operating space; and a stable base 103 horizontally extending at the bottom and designed with a box structure, with crisscross stiffening ribs arranged inside, which is used to disperse the weight of the device and enhance stability.

[0035] To further optimize the above technical solution, the adjustment mechanism 200 is used to control the lifting of the telescopic gate 300, and the specific structure is as follows: The drive motor mechanism 201 is fixedly connected to the central area of the support platform 101, using a three-phase asynchronous motor with a power of 30 kW and a rated speed of 1470 r / min, equipped with a reducer with a reduction ratio of 1:30, and the output shaft is connected to the screw mechanism 202 through a coupling. The screw mechanism 202 uses a trapezoidal thread screw. The nut mechanism 203 is matched with the screw mechanism 202 through a trapezoidal thread, and the nut mechanism 203 can move linearly along the screw mechanism 202. The connecting column 204 is horizontally and fixedly connected to the nut mechanism 203, and its two ends are respectively welded to the transverse connecting column 205. The transverse connecting column 205 is vertically and fixedly connected to the connecting column 204, and lifting columns 207 are symmetrically arranged at both ends. The lifting column 207 uses a seamless steel pipe of φ200×12, with a material of Q345D, and the surface is treated with hot-dip galvanization. M36 bolt holes are opened at the lower end thereof and respectively nested into two groups of positioning support mechanisms 206.

[0036] To further optimize the above technical solution, the telescopic gate 300 is used to intercept water flow, and the telescopic gate 300 has a double-layer structure, with a sliding connection between the upper and lower sections of the gate. The specific structure is as follows:

[0037] The gate panel is coated with epoxy zinc-rich primer and chlorinated rubber topcoat on the surface, having good anti-corrosion performance. Transverse and longitudinal stiffening ribs are welded on the front of the gate panel to enhance the stiffness and strength of the gate. At the top of the telescopic gate 300 corresponding to the bolt holes at the lower end of the lifting column 207, M36 bolt holes are opened and fixedly connected to the lifting column 207 through high-strength bolts.

[0038] To further optimize the above technical solution, the positioning pile mechanism 400 is used to fix the entire device, and its specific structure is as follows: The positioning sleeve 403 is fixedly connected to the stable base 103 through a flange, and its length is 2 meters to ensure that the orientation column 401 is vertically driven into the riverbed. The orientation column 401 is nested inside the positioning sleeve 403, and its surface is carburized and quenched. The lower end of it is processed into a conical shape for easy driving into the riverbed, and its length is determined according to the geological conditions of the riverbed. The limit column 402 is horizontally placed at a certain height of the orientation 401 and welded to the orientation column 401 to form a "cross" structure. Its installation height can be adjusted according to the driving depth into the riverbed, generally 5-7 meters away from the lower end of the orientation column 401, and is used to pull out the positioning column 401 by a crane after the later construction is completed.

[0039] A water conservancy construction closure method disclosed by the present invention includes the following steps:

[0040] S1. Device transportation and installation:

[0041] Before the water conservancy construction closure, each component of the closure device is transported to the closure site by a transport ship. First, use a crane to lift the main frame 100 to a predetermined position, and ensure the accurate position of the main frame 100 through the cooperation of the guide wheels and guide rails. Then, the adjustment mechanism 200, the telescopic gate 300 and the positioning pile mechanism 400 are successively installed on the main frame 100 and debugged to ensure the normal operation of each mechanism.

[0042] S2. Driving the positioning pile:

[0043] Start the hydraulic hammer (model D62-22, impact energy 62kJ), and drive the orientation column 401 into the riverbed to a certain depth (generally 5-8 meters) through the positioning sleeve 403 and the stable base 103 until the design bearing capacity requirements are met. During the driving process, the verticality and penetration depth of the orientation column 401 are monitored in real time by a theodolite and a level to ensure accurate positioning. Drive the orientation column 401 to the depth of the predetermined limit column 402.

[0044] S3. Control the lifting of the telescopic gate:

[0045] Start the drive motor mechanism 201, the motor drives the screw mechanism 202 to rotate through a speed reducer. Since the nut mechanism 203 is in threaded cooperation with the screw mechanism 202 and a guide key is arranged on the outside of the nut mechanism 203, the nut mechanism 203 moves linearly along the screw mechanism 202, driving the connecting column 204, the transverse connecting column 205 and the lifting column 207 to lift and lower together. The lifting column 207 is fixedly connected to the telescopic gate 300 through bolts, thereby realizing the lifting control of the telescopic gate 300. During the lifting and lowering process, the positioning support mechanism 206 ensures the vertical lifting and lowering of the lifting column 207 and improves the control accuracy.

[0046] S4. Closure process:

[0047] When closure is required, start the drive motor mechanism 201 to raise the telescopic gate 300 to the top of the riverbank to form a complete closure surface. The water flow is blocked by the telescopic gate 300.

[0048] S5. Device removal:

[0049] When the closure is completed and subsequent construction is required or the closure device needs to be removed, use a crane to pull out the orientation column 401 from the riverbed through the limit column 402. Finally, remove each component of the closure device in sequence and transport it to the designated location for storage or for the next closure operation.

[0050] The present invention has the following remarkable advantages: Through the positioning pile mechanism, the position and verticality of the device can be accurately controlled to ensure that the closure device is accurately installed at the predetermined position. The efficient lifting and adjusting mechanism: The adjusting mechanism adopts the screw-nut transmission method, which has the advantages of high transmission efficiency, high positioning accuracy, and large load-bearing capacity, and can realize the precise lifting control of the telescopic gate. By the forward and reverse rotation of the drive motor mechanism 201, the telescopic gate can be quickly raised and lowered, greatly improving the construction efficiency. In addition, the main frame, adjusting mechanism, telescopic gate, and positioning pile mechanism all adopt modular design, which is convenient for transportation, installation, and disassembly. The reusable closure device of the present invention has a strong structure and a long service life. After the construction is completed, it can be easily removed and recycled, with a high reuse rate, reducing the project cost. The orientation column in the positioning pile mechanism can be easily pulled out through the limit column without causing permanent damage to the riverbed, meeting the environmental protection requirements.
