Abstract

This invention discloses a construction device for underwater equipment, including a protective frame, multiple protective rods on the inner wall of the protective frame, an isolation plate on the inner wall of the protective frame, a vertical shaft on the inner wall of the isolation plate, steps inside the vertical shaft, a ventilation device inside the isolation plate, a fixed platform on the top surface of the protective frame, and a water pumping device on the top surface of the fixed platform. By turning on the water pump, the water source inside the inner plate is introduced into the water pumping pipe, and the clean water flows from the water pumping pipe to the water outlet pipe and out from the water distribution pipe, so that the device can discharge the clean water between the inner plate and the inner plate and the outer plate, creating a construction environment for personnel.

Description

Technical Field

[0001] This invention belongs to the field of underwater construction, specifically to a construction device and method for underwater equipment. Background Technology

[0002] A cofferdam is a temporary retaining structure built in hydraulic engineering projects to construct permanent hydraulic facilities. Its function is to prevent water and soil from entering the construction site of the underwater structure, facilitating dry trench construction within the cofferdam. Cofferdams are generally used in hydraulic engineering structures, and most cofferdams need to be dismantled after use, except for a few that are part of a formal underwater structure.

[0003] Existing document CN 109469080 A discloses an underwater rock-embedded steel sheet pile cofferdam structure and its construction method. The underwater rock-embedded steel sheet pile cofferdam structure includes an annular cofferdam formed by multiple steel sheet piles and an inner support located inside the annular cofferdam. The lower part of the annular cofferdam is fixed in the rock-embedded groove with concrete. After drilling the rock-embedded groove in the bedrock layer, concrete is poured into the rock-embedded groove space inside and outside the annular cofferdam simultaneously through a hopper device, thereby fixing the lower part of the annular cofferdam in place within the rock-embedded groove.

[0004] The existing literature on cofferdams is complex and cumbersome to construct, and cannot be reused, resulting in high costs for underwater construction. Summary of the Invention

[0005] This invention provides a construction apparatus for underwater equipment, the technical solution of which is as follows:

[0006] The present invention provides a construction device for underwater equipment, comprising a protective frame, a plurality of protective rods on the inner wall of the protective frame, an isolation plate on the inner wall of the protective frame, a vertical shaft on the inner wall of the isolation plate, a staircase inside the vertical shaft, a ventilation device inside the isolation plate, a fixed platform on the top surface of the protective frame, and a water pumping device on the top surface of the fixed platform.

[0007] The insulating plate of the present invention includes an outer plate, a buffer member and an inner plate. The inner wall of the outer plate is provided with a plurality of buffer members, and the inner plate is provided on one side surface of the buffer member. The two ends of the buffer member are horizontally deflected from the inner plate and the outer plate within a certain angle range.

[0008] The buffer component of this invention includes a buffer seat, a buffer spring, and a buffer rod. The buffer seat is installed on the inner plate, and a buffer spring is provided inside the buffer seat. A buffer rod is provided on one side of the buffer spring, and one end of the buffer rod passes through the buffer seat and is connected to the inner wall of the outer plate.

[0009] The ventilation device of the present invention includes a ventilation hood, an air inlet, a fixing frame, a ventilation fan, a ventilation duct, and fixing hoops. The top surface of the ventilation hood is provided with an air inlet, the inner wall of the ventilation hood is provided with a fixing frame, the inner wall of the fixing frame is provided with a ventilation fan, the bottom surface of the ventilation hood is provided with a ventilation duct, and the surface of the ventilation duct is provided with multiple fixing hoops.

[0010] The fixing hoop surface of the present invention is bolted to the inner wall of the inner plate.

[0011] The water pumping device of the present invention includes a water pumping base, a water pump, a water pumping pipe, a water outlet pipe and a water distribution pipe. The water pump is installed inside the water pumping base. A water pumping pipe is installed on one side of the surface of the water pump, and a water outlet pipe is installed on the other side of the water pump. Multiple water distribution pipes are installed on the surface of the water outlet pipe.

[0012] The protective frame of the present invention is provided with equally spaced drive components on the bottom outer side. The drive components include a sealed box, a servo motor is installed inside the sealed box, and a rotary drill bit is fixedly installed at the output end of the servo motor. The rotary drill bit is used to drill down to fix the protective frame.

[0013] Multiple outward-extending components are evenly installed at the bottom of the protective frame. The outward-extending components include outward-extending rod one and outward-extending rod two. A guide pin is installed on outward-extending rod one. A vertical guide rail is provided on the protective frame. The guide pin is slidably engaged with the vertical guide rail. A spring is provided between outward-extending rod one and outward-extending rod two. A connecting pin is installed on outward-extending rod two. The connecting pin is rotatably installed on the protective frame. The bottom of outward-extending rod one and outward-extending rod two are rotatably installed. A sealing sheet is wrapped around the outside of outward-extending rod one. A connecting shaft is rotatably installed on outward-extending rod two. A torsion spring is installed at the rotation node. A winding wheel is fixed on the drive shaft. A connecting rope 9 is wound on the winding wheel. A partition is installed on the connecting shaft. The free end of the sealing sheet abuts against the surface of the partition.

[0014] A transmission wheel is mounted on the output shaft of the servo motor. The transmission wheel is connected to an output wheel via a gear assembly. One end of the connecting rope is fixed to the output wheel. The servo motor drives the transmission wheel to rotate, which in turn drives the connecting shaft to rotate via the gear assembly and the connecting rope. This causes the partition to deflect outward and anchor into the underwater foundation. This forms a stable structure with a smaller top and a larger bottom for the protective frame. The partition increases the anchoring area and strength, and also helps to fix the protective frame during drilling. As the protective frame sinks, it can effectively level the underwater foundation.

[0015] The partition component of the present invention includes a body fixedly installed with a connecting shaft. The side of the body that is deflected outward is a tapered structure. Partition plates are slidably installed on both sides of the body. The partition plates move to both sides relative to the body and are adapted to adjacent partition plates.

[0016] The present invention relates to a drive body installed between two partition plates located on the same partition member. Each end of the drive body is hinged with a drive rod, which is rotatably mounted on the partition plate. The drive body is slidably mounted on the back of the main body and connected to it via a spring. An elastic telescopic rod is installed on the protective frame, one end of which is rotatably connected to the drive body, and the other end is vertically slidably fitted onto the protective frame and rotatably connected relative to it. An underwater foundation partition structure is provided on the outside of the partition plates. The partition structures are combined to form an isolation foundation, which reduces the frequency of pumping operation and effectively extends the construction time.

[0017] A method for using a construction device for underwater equipment, comprising the following steps:

[0018] The protective frame is vertically lowered into the water. The rotating nodes of the first and second outward extension rods at the bottom of the protective frame will first contact the underwater foundation. As the lowering continues, the protective frame sinks, causing the top of the first outward extension rod to rise. At the same time, the rotating nodes of the first and second outward extension rods unfold outward, and the angle between them gradually increases. The spring is gradually stretched, leveling the underwater foundation structure outward, until the first outward extension rod rises to its highest point.

[0019] The servo motor drives the rotary drill bit to drill down and fix the protective frame. At the same time, the transmission wheel, output wheel and connecting rope drive the connecting shaft to rotate. The partition deflects outward until the top of the elastic telescopic rod descends to the lowest point. As the partition continues to rotate outward, the length of the elastic telescopic rod will be stretched, which will drive the drive body to move upward relative to the main body and compress the spring until the partition plates of the two adjacent partitions abut against each other and seal. The sealing plate seals against the water-facing side of the partition, and finally the protective frame forms a stable structure with a small top and a large bottom.

[0020] The isolation plate is placed vertically inside the protective frame. The outer and inner plates together isolate the water source. The water pump is turned on, and the water pump introduces the water source inside the inner plate into the water pumping pipe. The clean water flows from the water pumping pipe to the water outlet pipe and flows out from the water distribution pipe, so that the device can discharge the clean water between the inner plate and the inner plate and the outer plate, creating a construction environment for personnel.

[0021] Construction workers climb stairs from inside the shaft to the bottom of the inner panel. Ventilation fans draw air into the ventilation hood from the air inlet, and the airflow from the fans blows the air into the ventilation ducts. The air then flows from the ventilation ducts to the bottom of the inner panel, ensuring a safe working environment for the workers inside.

[0022] Beneficial effects

[0023] 1. This invention eliminates the need for drilling holes on the water surface to construct installation trenches, effectively reducing construction costs, shortening the construction cycle, and improving work efficiency. By dumping and filling sand to form a foundation cover layer for positioning steel sheet piles, a construction environment with a cover layer on the underwater bare rock bedrock is created. The steel sheet piles are then driven and the cofferdam is closed to complete the steel sheet pile cofferdam construction. The steel sheet pile installation and positioning are accurate and the construction technology is simple, reducing equipment requirements and achieving efficient and high-quality cofferdam construction.

[0024] 2. This invention utilizes a water pump to draw water from the inner panel into a pumping pipe. The clean water flows from the pumping pipe to the outlet pipe and out through the distribution pipe, thus draining the water from the inner panel and the area between the inner and outer panels. This creates a suitable working environment for personnel. A ventilation fan draws air into the ventilation hood from the air inlet, directing the air towards the ventilation duct. The air then flows from the ventilation duct to the bottom of the inner panel, ensuring a safe working environment for personnel and preventing oxygen deficiency. Since this invention is applied to underwater construction, it often faces the challenge of resisting water flow impacts. Protective rods can be installed on the protective frame to prevent larger objects in the water from impacting the outer panel. When smaller objects impact, the impact force moves the outer panel, which in turn moves a buffer rod. The buffer rod then moves a buffer spring, which is compressed inside the buffer seat, thus buffering the external impact force, preventing damage to the device, and extending its service life.

[0025] 3. This invention, through the combination of an outward-extending component at the bottom, a servo motor, and a rotary drill bit, effectively secures the protective frame to an underwater foundation. During the drilling process, driven by the servo motor and the rotary drill bit, the connecting shaft rotates downwards and expands outwards via a transmission wheel, gear assembly, and connecting rope, anchoring into the underwater foundation. As the anchoring position deepens, the elastic telescopic rod moves the driving body upwards relative to the main body, thereby expanding the partition plates to both sides and achieving a tight fit with adjacent partition plates. Due to the outward extension of the partition plates, the sealing sheet (elastic rubber sheet) can be tightly fitted to the outer wall of the partition. After water is pumped out by the pumping device, the sealing fit to the outer wall of the partition is further enhanced. When the servo motor drives the transmission wheel to rotate in the opposite direction, the partition (under the action of the torsion spring) retracts inwards, and the elastic telescopic rod retracts. When the driving body returns to its original position, it can retract the partition plate inwards. As the protective frame is lifted away, the angles of outward-extending rod one and outward-extending rod two decrease, and the top of outward-extending rod one descends to its initial height.

[0036] The embodiments of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only for illustration and explanation of the present invention and are not intended to limit the present invention.

[0037] In the attached diagram, all identical reference numerals refer to the same components.

[0038] Example

[0039] like Figure 1-5 As shown, the present invention provides a construction device for underwater equipment, including a protective frame 1, an isolation plate 3 provided on the inner wall of the protective frame 1, a vertical shaft 4 provided on the inner wall of the isolation plate 3, a staircase 5 provided inside the vertical shaft 4, a ventilation device 6 provided inside the isolation plate 3, a fixed platform 7 provided on the top surface of the protective frame 1, and a water pumping device 8 provided on the top surface of the fixed platform 7.

[0040] The insulating plate 3 includes an outer plate 301, a buffer member 302 and an inner plate 303. The inner wall of the outer plate 301 is provided with a plurality of buffer members 302. The inner plate 303 is provided on one side surface of the buffer member 302. The two ends of the buffer member 302 are horizontally deflected from the inner plate 302 and the outer plate 301 within a certain angle range.

[0041] The buffer component 302 includes a buffer seat 3021, a buffer spring 3022, and a buffer rod 3023. The buffer seat 3021 is installed on the inner plate 303. The buffer spring 3022 is provided inside the buffer seat 3021. The buffer rod 3023 is provided on one side of the buffer spring 3022, and one end of the buffer rod 3023 passes through the buffer seat 3021 and is connected to the inner wall of the outer plate 301.

[0042] The ventilation device 6 includes a ventilation hood 601, an air inlet 602, a fixing frame 603, a ventilation fan 604, a ventilation duct 605, and fixing clamps 606. The air inlet 602 is provided on the top surface of the ventilation hood 601, the fixing frame 603 is provided on the inner wall of the ventilation hood 601, the ventilation fan 604 is provided on the inner wall of the fixing frame 603, the ventilation duct 605 is provided on the bottom surface of the ventilation hood 601, and multiple fixing clamps 606 are provided on the surface of the ventilation duct 605.

[0043] The surface of the fixing hoop 606 is bolted to the inner wall of the inner plate 303.

[0044] The water pumping device 8 includes a water pump base 801, a water pump 802, a water pump pipe 803, a water outlet pipe 804, and a water distribution pipe 805. The water pump 802 is installed inside the water pump base 801. The water pump pipe 803 is installed on one side of the surface of the water pump 802, and the water outlet pipe 804 is installed on the other side of the water pump 802. Multiple water distribution pipes 805 are installed on the surface of the water outlet pipe 804.

[0045] Specifically, before the device is used, the protective frame 1 is hoisted into the water, and the isolation plate 3 is placed inside the inner wall of the protective frame 1. The outer plate 301 and the inner plate 303 isolate the water source. The water pump 802 is turned on, and the water pump 802 introduces the water source inside the inner plate 303 into the water pumping pipe 803. The clean water flows from the water pumping pipe 803 to the water outlet pipe 804 and flows out from the water distribution pipe 805, so that the device can discharge the clean water between the inner plate 203 and the outer plate 201, creating a construction environment for personnel. When the device is used, the construction personnel climb the ladder 5 from inside the shaft 5 to enter the bottom of the inner plate 203. The ventilation fan 604 introduces air into the ventilation hood 601 from the air inlet 602. The air force of the ventilation fan 604 blows the air towards the ventilation duct 605. The air flows from the ventilation duct 605 to the bottom of the inner plate 203, so that the device can guarantee the construction environment for the personnel inside.

[0046] During construction, when the water flow is fast, multiple protective rods 2 can be installed on the inner wall of the protective frame 1. The protective rods 2 can block larger heavy objects in the water from impacting the outer plate 301. When a smaller heavy object impacts, the impact force drives the outer plate 301, which in turn drives the buffer rod 3023. The buffer rod 3023 then drives the buffer spring 3022, which is compressed inside the buffer seat 3021. This buffers the external impact force, prevents damage to the device, and extends its service life.

[0047] In summary, this invention, by turning on the water pump, introduces water from inside the inner panel into the water pipe. The clean water flows from the water pipe to the water outlet pipe and out through the branch pipe, thus draining the water from the inner panel and the area between the inner and outer panels, creating a suitable working environment for personnel. A ventilation fan introduces air into the ventilation hood from the air inlet, and the fan blows the air towards the ventilation duct, allowing it to flow towards the bottom of the inner panel. This ensures a safe working environment for personnel inside the device, preventing oxygen deficiency. A protective rod prevents large objects in the water from impacting the outer panel. When a smaller object impacts, the impact force moves the outer panel, which in turn moves the buffer rod. The buffer rod then moves the buffer spring, which is compressed inside the buffer seat, thus buffering external impacts, preventing damage to the device, and extending its service life.

[0048] In Example 2, in the construction device for the underwater equipment described above, in order to ensure the stability of the protective frame 1 underwater, drive components are provided at equal intervals on the outer side of the bottom of the protective frame 1. The drive components include a sealing box 101, a servo motor 102 is installed inside the sealing box 101, and a rotary drill bit 103 is fixedly installed at the output end of the servo motor 102. The rotary drill bit 103 is used to drill down to fix the protective frame 1.

[0049] Multiple outward-extending components are evenly installed at the bottom of the protective frame 1. Each outward-extending component includes an outward-extending rod one 104 and an outward-extending rod two 105. A guide pin is installed on the outward-extending rod one 104. A vertical guide rail 1041 is provided on the protective frame 1. The guide pin is slidably engaged with the vertical guide rail 1041. A spring is provided between the outward-extending rod one 104 and the outward-extending rod two 105. A connecting pin is installed on the outward-extending rod two 105, and the connecting pin is rotatably mounted on the protective frame 1. The bottom of 05 is rotatably installed. The outer side of the first extension rod 104 is wrapped with a sealing plate 106. The top of the sealing plate 106 is sealed and fixed to the outer wall of the protective frame 1. The second extension rod 105 is rotatably installed with a connecting shaft 107, and a torsion spring is installed at the rotation node. A winding wheel 108 is fixed on the transmission shaft. A connecting rope 109 is wound on the winding wheel 108. A partition 1010 is installed on the connecting shaft 107, and the free end of the sealing plate 106 abuts against the surface of the partition 1010.

[0050] A transmission wheel 1021 is mounted on the output shaft of the servo motor 102. The transmission wheel 1021 is connected to the output wheel 1022 through a gear assembly. One end of the connecting rope 109 is fixed to the output wheel 1022. The servo motor 102 drives the transmission wheel 1021 to rotate, which in turn drives the connecting shaft 107 to rotate through the gear assembly and the connecting rope 109, thus deflecting the partition 1010 outward and anchoring it into the underwater space foundation.

[0051] When the protective frame 1 is hoisted and lowered, the rotating nodes of the outward extension rod 104 and the outward extension rod 2 105 drive the sealing plate 106 to contact the underwater foundation, expand outward, and roughly level the underwater foundation. During the process, the angle between the two increases. At the same time, the guide pin of the outward extension rod 104 will move upward along the vertical guide rail 1041 until the highest point, as shown in the figure. Then, the servo motor drives the rotary drill bit 103 to drill down and fix the protective frame 1. And through the transmission wheel 1021 and the gear assembly, it drives the output wheel 1022 to rotate, tightening the connecting rope 109 until the connecting shaft 107 is rotated through the connecting rope 109, so that the air gap 1010 is anchored into the underwater space foundation, forming a stable structure with a large bottom and a small top, and reinforcing the construction device.

[0052] In Example 3, based on Example 2, in order to solve the problems of severe water seepage in underwater foundations, short construction time, and low construction efficiency, the partition 1010 includes a body 1011 fixedly installed with the connecting shaft 107. The side of the body 1011 that is deflected outward is a tapered structure, which is conducive to anchoring. Partition plates 1012 are slidably installed on both sides of the body 1011. The partition plates 1012 move to both sides relative to the body 1011 and are adapted to the adjacent partition plates 1012.

[0053] A drive body 1013 is installed between two partition plates 1012 located on the same partition member 1010. Drive rods 1014 are respectively hinged to both ends of the drive body 1013. The drive rods 1014 are rotatably installed on the partition plate 1012. The drive body 1013 is slidably installed on the back of the body 1011 and is connected to the body 1011 by a spring. An elastic telescopic rod 1015 is installed on the protective frame 1. One end of the elastic telescopic rod 1015 is rotatably connected to the drive body 1013, and the other end is vertically slidably engaged with the protective frame 1 and rotatably connected relative to the protective frame 1. During the anchoring process of partition 1010, as the anchoring depth increases, before partition 1010 achieves vertical separation, the drive body 1013 is lifted and the spring is compressed by the elastic telescopic rod 1015, causing the drive rod 1014 to drive the partition plate 1012 to move outward. When partition 1010 is in a vertical state, partition plate 1012 is fully extended, allowing it to fit and seal with the partition plate 1012 of the adjacent partition 1010. After sealing, it can partially isolate the water source from the underwater foundation outside the partition plate 3, lower the water level inside the partition plate 3, and increase the construction time.

[0054] The operating procedures for using the underwater equipment construction device are as follows:

[0055] The protective frame 1 is vertically lowered into the water. The rotating nodes of the outward extension rod 104 and the outward extension rod 2 105 at the bottom of the protective frame 1 will first contact the underwater foundation. As the lowering continues, the protective frame 1 sinks, causing the top of the outward extension rod 104 to rise. At the same time, the rotating nodes of the outward extension rod 104 and the outward extension rod 2 105 unfold outward, and the angle between them gradually increases. The spring is gradually stretched, leveling the underwater foundation structure outward, until the outward extension rod 104 rises to its highest point.

[0056] Servo motor 102 drives the rotary drill bit to drill down and fix the protective frame 1. At the same time, the transmission wheel 1021, output wheel 1022 and connecting rope 109 drive the connecting shaft 107 to rotate. The partition 1010 deflects outward until the top of the elastic telescopic rod 1015 descends to the lowest point. As the partition 1010 continues to rotate outward, the length of the elastic telescopic rod 1015 will be stretched, driving the drive body 1013 to move upward relative to the body 1011 while compressing the spring, until the partition plates 1012 of the two adjacent partitions 1010 abut against each other and seal, and the sealing plate 106 seals against the water-facing side of the partition 1010. Finally, the protective frame 1 forms a stable structure with a small top and a large bottom.

[0057] The isolation plate 3 is placed vertically inside the protective frame 1. The outer plate 301 and the inner plate 303 together isolate the water source. The water pump 802 is turned on, and the water pump 802 introduces the water source inside the inner plate 303 into the water pumping pipe 803. The clean water flows from the water pumping pipe 803 to the water outlet pipe 804 and flows out from the water distribution pipe 805, so that the device discharges the clean water between the inner plate 203 and the outer plate 201, creating a construction environment for personnel.

[0058] Construction workers climb stairs 5 from inside the shaft 4 to enter the bottom of the inner panel 203. The ventilation fan 604 introduces air into the ventilation hood 601 from the air inlet 602. The airflow from the ventilation fan 604 blows the air towards the ventilation duct 605. The air flows from the ventilation duct 605 to the bottom of the inner panel 203, ensuring a safe working environment for the workers inside the device.

[0059] Once construction is complete, the servo motor 102 reverses its movement to reset the rotary drill bit 103, releasing the locking state of the protective frame 1. Subsequently, the protective frame 1 is lifted away. After the partition 1010 separates from the underwater foundation, the connecting shaft 107 resets under the action of the torsion spring, and at the same time, the outward extension rod 104, the outward extension rod 2 105, the elastic telescopic rod 1015, and the drive body 1013 reset.
