Description

Technical Field

[0001] The invention relates to the field of water intake project construction, and in particular to a method for installing a water intake head for non-navigable waters. Background Art

[0002] The water intake head is an important part of the water intake project. It is mainly a facility located at the submerged or semi-submerged riverbed to draw water into the water inlet pipe through its water inlet hole. The main function of the water intake head is to prevent floating objects from being sucked into the pipe. At the same time, it is necessary to solve problems such as siltation and weed blockage that may be encountered during operation.

[0003] Patent No. CN113374935A discloses a construction method for underwater installation of the water intake head of a water plant by a ship crane method, and the construction method comprises: step 1, using a car crane on a lifting ship to move the water intake head unit to a floating crane lifting position; step 2, using a floating crane to lift the water intake head components from the shore platform, and then transporting them to the water installation point by the lifting ship for the next step of underwater installation; step 3, using the lifting ship to sink the water intake head unit to the underwater installation point, and a diver to install the water intake head underwater. The construction method for underwater installation of the water intake head of a water plant by a ship crane method has the advantages of low construction difficulty and high installation efficiency.

[0004] In the prior art, the water intake head is transported to the installation point on the water by a crane ship, and then the water intake head is sunk by the crane ship to the underwater installation point for assembly. However, the crane ship generally sinks the water intake head to the underwater installation point by lifting it with a steel cable. Because crosswinds may blow the lake surface when lifting and installing it on the water surface, waves may be generated on the lake surface. In this way, when lifting and installing with a steel cable, wave disturbances may be caused by the crosswinds on the steel cable, causing the steel cable and the prefabricated water intake head to shake due to the waves, which will affect the installation calibration of the water intake head and increase the difficulty and danger of construction. In addition, the shaking water intake head may easily hit the crane ship, causing damage to the water intake head and the crane ship, resulting in danger or the water intake head is damaged and cannot be used anymore. Summary of the invention

[0005] The purpose of the present invention is to provide a method for installing a water intake head in non-navigable waters to solve the following technical problems:

[0006] When lifting and hoisting on the water surface, there will be crosswinds, which will cause the wire rope on the lifting to shake violently, causing the prefabricated parts of the water intake head to shake as well, making the lifting and installation construction more difficult. It may also cause the shaking prefabricated parts of the water intake head to easily hit the crane ship, causing damage to the prefabricated parts of the water intake head and the crane ship.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

The specific installation steps are as follows: the surveying personnel firstly perform the point layout, check whether the installation point of the water intake head prefabricated parts is deviated, and then use the driving component to drive the lifting component to rotate. The rotating lifting component will slowly place the water intake head prefabricated parts downward. The driving component will drive the lifting component and also drive the limit component to move. The moving limit component prevents the lifting component from being shaken by the crosswind, so that the lifting component can smoothly lift and install the water intake head prefabricated parts into the water intake head foundation pit;

[0012] S4, after the prefabricated water intake head is stably placed in the foundation pit of the water intake head, underwater concrete is poured to the bottom of the water intake head, and blocks are thrown around the water intake head;

[0013] S5, after the water intake head prefabricated parts at the bottom are installed and fixed, the remaining water intake head prefabricated parts are stacked and installed in sequence by using the lifting and installation module until all the water intake head prefabricated parts are installed.

[0014] Furthermore, the lifting and installation module includes a top plate; and further includes:

[0015] A hoisting assembly is arranged on the top of the top plate and is used to lift and place the water intake head prefabricated parts;

[0016] The limit assembly is set at the bottom of the top plate to keep the water head prefabricated parts stable when lifting them with the limit lifting assembly;

[0021] Further, the driving assembly also includes a worm gear and a moving worm;

[0022] The limiting assembly includes a column, a movable plate and a movable groove;

[0023] Among them, the column is fixedly set at the bottom of the top plate; there are four columns, and they are respectively arranged near the center position of the bottom of the top plate; the movable plate is slidably set on the column; the top of the movable plate is rotatably connected with a movable worm; the movable worm passes through the top plate; the vortex gear is meshed with the movable worm; the movable groove is opened at the center position of the movable plate.

[0024] Furthermore, the limiting assembly also includes a roller and a limiting block;

[0025] Among them, the roller is slidably arranged in the moving groove; two rollers are provided and symmetrically arranged in the moving groove; and the limiting block is rotatably arranged on the roller.

[0026] Furthermore, a sliding block is slidably connected to the column; a spring is sleeved on the column; and two ends of the spring are respectively fixed to the sliding block and the bottom of the column.

[0027] Furthermore, the retractable wheel is provided with two grooves, and the steel wire ropes of equal length are respectively placed in the two grooves.

[0028] Furthermore, an L-shaped support frame is fixedly connected to the bottom of the top plate; four L-shaped support frames are provided and are respectively arranged at the four corners of the top and bottom; a reinforcing column is fixedly connected to the L-shaped support frame; and a floating block is fixedly connected to the bottom of the L-shaped support frame.

[0029] Beneficial effects of the present invention:

[0030] (1) The steel wire rope located above the movable plate is straightened and tightened by the lifting movable plate, and then the movable plate is extended under the waves on the water surface. In this way, the steel wire rope located on the movable plate is straightened and tightened, so when the waves generated by the crosswind on the water surface are blown, the steel wire rope will not be shaken violently, thereby avoiding the shaking of the steel wire rope and the prefabricated parts of the water intake head due to the waves generated by the crosswind blowing on the water surface, thereby increasing the difficulty of construction or causing collision accidents, resulting in damage to the prefabricated parts of the water intake head;

[0031] (2) The steel wire rope is passed through a limiting block in the movable groove, and a roller is provided on the limiting block so that the limiting block can slide in the movable groove. In this way, when the water intake head on the steel wire rope needs to be fine-tuned underwater, the roller on the limiting block can slide in the movable groove, so that the prefabricated part of the water intake head can reach the specified position, thereby avoiding the situation where the steel wire rope above the movable plate is tightened, resulting in the steel wire rope being unable to move.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 5 As shown, the present invention is a method for installing a water intake head for non-navigable waters, comprising the following steps:

[0041] S1, first use a dredger to excavate the foundation pit for the installation location of the water intake head. After the foundation pit of the water intake head is excavated, a crushed stone cushion layer is laid in the foundation pit of the water intake head for leveling;

[0042] S2, after the foundation pit is leveled, the prefabricated water intake head prefabricated parts are delivered to the top of the water intake head foundation pit by using a box-type floating boat;

[0043] S3, when the water intake head is delivered to the top of the water intake head foundation pit by the box-type floating boat, the lifting and installation module is used to lift and install the water intake head prefabricated parts. The specific installation steps are as follows: the surveyor first performs the point layout, checks whether the installation point of the water intake head prefabricated parts is deviated, and then uses the driving component 03 to drive the lifting component 01 to rotate. The rotating lifting component 01 will slowly place the water intake head prefabricated parts downward. The driving component 03 drives the lifting component 01 and also drives the limit component 02 to move. The moving limit component 02 prevents the lifting component 01 from being shaken by the crosswind, allowing the lifting component 01 to smoothly lift and install the water intake head prefabricated parts into the water intake head foundation pit;

[0044] S4, after the prefabricated water intake head is stably placed in the foundation pit of the water intake head, underwater concrete is poured to the bottom of the water intake head, and blocks are thrown around the water intake head;

[0045] S5, after the water intake head prefabricated parts at the bottom are installed and fixed, the remaining water intake head prefabricated parts are stacked and installed in sequence by using the lifting and installation module until all the water intake head prefabricated parts are installed;

[0046] During operation, in the prior art, the water intake head is delivered to the installation point on the water for lifting and installation by a crane ship, but crosswinds will occur on the water, and the crosswinds will blow the lake surface to generate waves. The waves on the water surface will cause the steel cables in the lifting device and the prefabricated parts of the water intake head to shake, resulting in increased construction difficulty, and the shaking water intake head liquid is easy to collide with the crane ship, causing damage to the water intake head and the crane ship, causing danger or the water intake head is damaged and can no longer be used. In order to prevent similar incidents from happening, the water intake head is lifted and installed by a lifting and installation module, and the lifting component 01 is driven to rotate by the driving component 03, so that the lifting component 01 slowly lowers the prefabricated parts of the water intake head, and at the same time, the driving component 03 will also move the limiting component 02, and the limiting component 02 limits the lifting component 01 to prevent the crosswind on the water surface from blowing the waves to scrape the lifting component 01, causing the lifting component 01 and the prefabricated parts of the water intake head to shake, resulting in increased construction difficulty and collision.

[0047] See also Figures 1 to 5 As shown, the lifting and installation module includes a top plate 3; and also includes:

[0048] The hoisting assembly 01 is arranged on the top of the top plate 3 and is used to lift and place the water intake head prefabricated component;

[0049] The limiting assembly 02 is arranged at the bottom of the top plate 3 to keep the water head prefabricated part stable when being lifted by the limiting lifting assembly 01;

[0050] The driving component 03 is arranged on the top of the top plate 3 and is used to drive the hoisting component 01 and the limiting component 02 to move;

[0051] By allowing the driving component 03 on the top plate 3 to drive the lifting component 01 to rotate, the lifting component 01 can lift and lower the prefabricated water intake head, and the prefabricated water intake head can be lowered into the excavated water intake head foundation pit. The limit component 02 moves to limit the lifting component 01 from being affected by the waves driven by the crosswind on the water surface, thereby avoiding violent shaking of the lifting component 01 and the prefabricated water intake head.

[0052] See also Figure 1 , Figure 2 and Figure 3 As shown, the driving assembly 03 includes a supporting column 4, a driving motor 5 and a rotating column 6;

[0053] The hoisting assembly 01 includes a retracting wheel 7, a steel wire rope 8, a through hole 11 and a hoisting ring 16;

[0054] Among them, the support column 4 is fixedly arranged on the top of the top plate 3; the support blocks are provided with two and are symmetrically arranged on the top plate 3; the rotating column 6 is rotatably arranged on the support column 4; the driving motor 5 is fixedly arranged on the support column 4, and the driving motor 5 is connected with the rotating column 6; the retracting wheel 7 is fixedly arranged on the rotating column 6; the wire rope 8 is wound on the retracting wheel 7; the through hole 11 is opened on the top plate 3; the wire rope 8 passes through the through hole 11; the lifting ring 16 is fixedly arranged at one end of the wire rope 8;

[0055] The driving motor 5 drives the rotating column 6 on the supporting column 4 to rotate, and the rotating rotating column 6 will drive the retracting wheel 7 to rotate. The rotating retracting wheel 7 will allow the steel wire rope 8 wound thereon to pass through the through hole 11 and move slowly downward. The water intake head prefabricated component is hung on the hanging ring 16 at the bottom of the steel wire rope 8 through the connecting rope. In this way, the rotation of the retracting wheel 7 will allow the steel wire rope 8 to drive the prefabricated component of the water intake head to move slowly downward. This setting can set the length of the steel wire rope 8 according to the depth below the water intake head, so that the prefabricated component of the water intake head can be accurately placed in the foundation pit of the water intake head at one time.

[0056] See also Figure 1 , Figure 2 and Figure 5 As shown, the driving assembly 03 also includes a worm gear 9 and a moving worm 10;

[0057] The position limiting assembly 02 includes a column 13, a movable plate 12 and a movable groove 17;

[0058] The column 13 is fixedly arranged at the bottom of the top plate 3; there are four columns 13, which are respectively arranged near the center of the bottom of the top plate 3; the moving plate 12 is slidably arranged on the column 13; the top of the moving plate 12 is rotatably connected with a moving worm 10; the moving worm 10 passes through the top plate 3; the vortex gear 9 is meshed with the moving worm 10; the moving groove 17 is opened at the center of the moving plate 12;

[0059] The vortex gear 9 is driven to rotate by the rotating rotating column 6, and a certain formed thread is provided on the moving worm 10, so that the rotating vortex gear 9 will cooperate with the thread on the moving worm 10 to allow the moving worm 10 to be lifted and lowered. The lifted moving worm 10 will cause the moving plate 12 to slide on the column 13, and the wire rope 8 passes through the moving groove 17 on the moving plate 12. This arrangement is for when the wire rope 8 carries the prefabricated parts of the water intake head to be lifted and installed into the foundation pit, the lifted moving plate 12 will straighten and tighten the wire rope 8 located above the moving plate 12, and then the moving plate 12 will extend under the waves on the water surface, so that the wire rope 8 located on the moving plate 12 is straightened and tightened, so when the crosswind on the water surface blows over the waves generated, the wire rope 8 will not shake violently, thereby avoiding the shaking of the wire rope 8 and the prefabricated parts of the water intake head due to the waves generated by the crosswind, thereby increasing the construction difficulty or causing a collision accident, causing damage to the prefabricated parts of the water intake head.

[0060] See also Figure 2 , Figure 3 and Figure 4 As shown, the limiting assembly 02 further includes a roller 20 and a limiting block 19;

[0061] The roller 20 is slidably disposed in the moving groove 17; two rollers 20 are provided and symmetrically arranged in the moving groove 17; the limiting block 19 is rotatably disposed on the roller 20;

[0062] The steel wire rope 8 is passed through the limiting block 19 in the movable groove 17, and the limiting block 19 is provided with a roller 20, so that the limiting block 19 can slide in the movable groove 17. In this way, when the water intake head on the steel wire rope 8 needs to be fine-tuned underwater, the roller 20 on the limiting block 19 can slide in the movable groove 17, so that the prefabricated part of the water intake head can reach the specified position, avoiding the situation that the steel wire rope 8 located above the movable plate 12 is tightened, thereby causing the steel wire rope 8 to be unable to move.

[0063] See also Figure 2 , Figure 3 and Figure 5 As shown, a sliding block 15 is slidably connected to the column 13; a spring 14 is sleeved on the column 13; two ends of the spring 14 are respectively fixed to the sliding block 15 and the bottom of the column 13;

[0064] By moving the worm 10, the moving plate 12 is moved downward. The downward movement of the moving plate 12 will press the spring 14 and the sliding block 15 to shrink the spring 14. Because the thread on the moving worm 10 is formed to a certain extent, when the vortex gear 9 slides out of this formation, the moving worm 10 will no longer rotate and the moving plate 12 will be lowered. When the moving plate 12 needs to rise, the vortex gear 9 will reverse. At this time, the compressed spring 14 will lose pressure, releasing the stress of the compressed spring 14 to push the sliding block 15 out and hit the moving plate 12 to make the moving plate 12 rise, so that the thread on the moving worm 10 contacts the vortex gear 9 and rotates and rises again.

[0065] See also Figure 1 , Figure 2 and Figure 5 As shown, the retractable wheel 7 is provided with two grooves, and the steel wire ropes 8 of equal length are respectively placed in the two grooves;

[0066] Two grooves are arranged on the retracting and unwinding wheel 7 and two sets of steel wire ropes 8 are arranged in the grooves so that when the prefabricated parts of the water intake head are lifted and placed, the prefabricated parts of the water intake head can be placed more stably by lowering them together with the two sets of steel wire ropes 8 to avoid tilting and deviation.

[0067] See also Figure 1 , Figure 2 and Figure 5 As shown, the bottom of the top plate 3 is fixedly connected to an L-shaped support frame 2; four L-shaped support frames 2 are provided, and are arranged at the four corners of the top and bottom respectively; a reinforcing column 18 is fixedly connected to the L-shaped support frame 2; a floating block 1 is fixedly connected to the bottom of the L-shaped support frame 2;

[0068] The top plate 3 is supported by the L-shaped support frame 2 and the floating block 1 at the bottom of the top plate 3. The reinforcing column 18 in the L-shaped support frame 2 is used to strengthen the stability of the L-shaped support column 4 to prevent the L-shaped support column 4 from being deformed due to the excessive weight of the prefabricated parts at the water intake head. The floating block 1 floats on the water surface, and the floating block 1 is equipped with an anchoring device, which can allow the floating block 1 to float stably on the water surface to prevent it from moving.

[0069] The working principle of the present invention: during operation, in the prior art, the water intake head is sent to the installation point on the water for lifting and installation by a crane ship, but crosswinds will be generated on the water, and the crosswinds will blow the lake surface to generate waves. The waves on the water surface will cause the steel cables in the lifting device and the prefabricated parts of the water intake head to shake, resulting in increased construction difficulty, and the shaking water intake head liquid is easy to collide with the crane ship, causing damage to the water intake head and the crane ship, causing danger or the water intake head is damaged and can no longer be used. In order to prevent similar incidents from occurring, the water intake head is lifted and installed by using a lifting and installation module, and the lifting assembly 01 is driven to rotate by the driving assembly 03, so that the lifting assembly 01 slowly lowers the prefabricated parts of the water intake head, and at the same time, the driving assembly 03 will also move the limiting assembly 02, and the limiting assembly 02 limits the lifting assembly 01 to prevent the crosswind on the water surface from blowing the waves to scrape the lifting assembly 01, causing the lifting assembly 01 and the prefabricated parts of the water intake head to shake, resulting in increased construction difficulty and collision;

[0070] The vortex gear 9 is driven to rotate by the rotating rotating column 6, and a certain formed thread is provided on the moving worm 10, so that the rotating vortex gear 9 will cooperate with the thread on the moving worm 10 to allow the moving worm 10 to be lifted and lowered. The lifted moving worm 10 will cause the moving plate 12 to slide on the column 13, and the wire rope 8 passes through the moving groove 17 on the moving plate 12. This arrangement is for when the wire rope 8 carries the prefabricated parts of the water intake head to be lifted and installed into the foundation pit, the lifted moving plate 12 will straighten and tighten the wire rope 8 located above the moving plate 12, and then the moving plate 12 will extend under the waves on the water surface, so that the wire rope 8 located on the moving plate 12 is straightened and tightened, so when the crosswind on the water surface blows over the waves generated, the wire rope 8 will not shake violently, thereby avoiding the shaking of the wire rope 8 and the prefabricated parts of the water intake head due to the waves generated by the crosswind, thereby increasing the construction difficulty or causing a collision accident, causing damage to the prefabricated parts of the water intake head.

[0071] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
