Description

[0001] This application is a divisional application of Chinese Patent Application No. 202011222427.8, entitled "A Heat Absorber Sliding Device", filed on November 5, 2020, the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of absorber installation technology, and particularly to a absorber installation method and absorber sliding device using an absorber sliding device. Background Technology

[0003] Tower molten salt solar thermal power generation technology has been commercialized on a large scale due to its advantages of high concentration ratio, high solar thermal conversion efficiency, continuous power generation at night, and autonomous peak shaving.

[0004] The main construction area of ​​a solar thermal power plant is divided into the mirror field area and the power island area. The power island area is the core of the entire power plant. All the solar energy is collected in the absorbers on the core building of the power island - the solar tower, which converts solar energy into thermal energy of molten salt. Steam is generated when the molten salt exchanges heat with water, thus generating electricity. The solar tower is a tall building, generally over 190m in height. It is different from the chimney of a conventional thermal power plant in that it is a comprehensive structure that integrates structure, equipment, pipelines, insulation, heat absorption, staircases and elevators, etc., making construction difficult.

[0005] After the ground assembly and acceptance of the receiver steel structure, equipment, and piping are completed, the receiver needs to be moved as a whole to its designated position directly below the receiver tower. Currently, most of the construction of the structure and equipment relies on external tower cranes for hoisting. Moving the receiver to its location beneath the receiver steel frame requires specialized power conversion equipment. Receivers are typically quite tall and heavy, usually assembled directly on support ring beams supplied by the receiver manufacturer. Therefore, including the weight of the support ring beams, the total weight for movement is very large, making it difficult to ensure safety and reliability during transportation. Comprehensive analysis and planning are needed for various details regarding the selection and installation of the transfer equipment, making it difficult to obtain scientific, reasonable, and economical machinery and installation solutions. This slows down the construction progress of the solar tower and results in extremely high construction costs.

[0006] Therefore, it is necessary to study a new receiver sliding device to efficiently and reliably transport the receiver from the assembly plant to the light tower, with precise final transfer location and low construction cost, thereby solving one or more of the aforementioned technical problems. Summary of the Invention

[0007] To address one or more technical problems in the prior art, in a first aspect, the present invention provides a method for installing a heat absorber using a heat absorber sliding device, comprising:

[0008] S10, Steps for installing the receiver sliding track: Before installation, check that the foundation of the sliding track has been completed and accepted; the quantity and quality of track materials and accessories have been counted and accepted; the track foundation and track are designed according to the receiver sliding requirements; and the foundation has been inspected by the general contractor and other units during handover. Ensure that the receiver sliding track consists of two parallel sliding rails.

[0009] S20, Installation steps for sliding shoes: Install the bottom floating plate of the sliding device inside the sliding track, hoist the bottom floating plate to the main oil top until the flange above the main oil top is close to the flange on the lower surface of the receiver ring beam, adjust the sliding device so that the flange of the main oil top is directly opposite the flange of the bottom plate of the supporting ring beam, and finally tighten the bolt connection.

[0010] S30, Sliding Heat Absorber Procedure: After checking and confirming that the sliding device is installed in the correct position, lift the central main jack until it contacts the flange of the supporting ring beam. The four sliding lifting devices are operated by one control system to ensure that the hydraulic lifting devices act simultaneously to lift the heat absorber horizontally.

[0011] In one or more embodiments, the step of installing the heat absorber sliding track includes:

[0012] S101, Check the track composition: The absorber sliding track consists of two parallel slide rails, with 19 slide rails on each line, each slide rail being 5.4m long, and the total length of a single track being 102.9m;

[0013] S102, Check the track installation method: The track is directly laid on the concrete foundation surface using a tower crane. After alignment and acceptance, each track is fixed to the foundation using four clips and bolts.

[0014] S103, Check the installation parameters and standards of the sliding rail.

[0015] Each track has 19 sliding rails, each 5.4 meters long, with a spacing of 16098±1.5 mm between them.

[0016] Maximum cross slope ±0.1%, maximum longitudinal slope ±0.5%;

[0017] The maximum longitudinal clearance between the two slide rails is 10mm;

[0018] The maximum planar deviation between the two slide rails is 1mm;

[0019] The maximum vertical gap between the two slide rails is 1mm.

[0020] In one or more embodiments, the sliding heat absorber step includes:

Carefully check the deformation of the track concrete foundation, track, and support ring beam, as well as the bolt connection status between the ring beam and the lifting device, and make relevant records.

[0022] S302, start 4 hydraulic lifting devices to simultaneously lift the support ring beam and the absorber by 200mm. Then start the sliding device, with each sliding distance being 600mm. During the sliding process, the computer control system monitors whether the stroke and load of each sliding device are consistent. The load of the sliding device should be basically consistent within one stroke, and the deviation should not exceed 5%. After each stroke of sliding is completed, the load and stroke of the pushing device are adjusted through the computer control system to ensure that the four sliding devices move synchronously. Repeat the above operation until the absorber slides to the position directly below the tower.

[0028] S403. During the sliding process, a high-precision level instrument is used to measure the real-time settlement of the sliding foundation to ensure sliding safety. If the settlement exceeds the overturning safety standard, it should be reported to the relevant design party for an assessment of the actual situation on site.

[0029] S404 monitors the on-site wind speed in real time during the sliding process, and stops sliding when the wind speed exceeds the standard requirements.

[0031] The sliding track consists of two parallel sliding rails, which are fixed to the ground by limit clips. The limit clips are fixed to the concrete foundation by bolts. The track foundation and sliding track are designed according to the sliding requirements of the heat absorber.

[0032] A support ring beam is installed at the bottom of the absorber and on the sliding track to support the absorber.

[0039] In one or more embodiments, the computer control system controls the sliding device to ensure that the load fluctuation deviation within one stroke does not exceed 5%.

[0040] In one or more embodiments, four sliding shoes are provided.

[0041] In one or more embodiments, pads are provided on the sliding track.

[0042] In one or more embodiments, the pad is made of polytetrafluoroethylene or high-density polyethylene.

[0043] In one or more embodiments, the bottom of the floating device is made of stainless steel.

[0044] In one or more embodiments, the floating device is a floating plate, which is installed in a sliding track. The bottom floating plate is hoisted to the main oil top until the flange above the main oil top is close to the flange on the lower surface of the absorber support ring beam. The sliding device is adjusted so that the flange above the main oil top is directly opposite the flange on the bottom plate of the support ring beam, and bolts are used for connection.

[0045] In one or more embodiments, each propulsion system is equipped with a power unit, a brake, and a control box. The power unit provides sufficient pressure and flow to achieve the designed coasting speed, the brake is used for braking the propulsion system, and the control box includes a control box housing, sensors, hydraulic valves, and connectors.

[0046] The hydraulic valve is connected to the housing via a connector;

[0047] The sensor is housed in the control box and is used to collect the following data during the operation of the receiver sliding device: main cylinder pressure load, main cylinder stroke, push / pull cylinder pressure or load, push / pull cylinder stroke, and lateral movement system.

[0051] An anemometer, connected to the bottom of the absorber, is used to monitor the on-site wind speed in real time during the sliding process. If the wind speed exceeds the standard requirements, the sliding will stop.

[0052] Compared with the prior art, the present invention has one or more of the following technical effects:

[0053] 1) The sliding device used has a simple structure, small size and light weight of the hoisting components, which can ensure safe construction and simple construction process;

[0054] 2) When the total weight of the moving equipment is very large, there is no need to consider the various details of the selection and installation of the transfer equipment. Thus, a scientific, reasonable and economical mechanical configuration and installation plan can be obtained through the sliding method, which can improve the construction progress of the optical tower and significantly reduce the construction cost.

[0055] 3) It can efficiently and reliably transport the absorber from the assembly plant to the light tower, and the final transfer location is accurate. It can be calculated and controlled according to the actual working conditions, and the equipment parameters can be adjusted in real time, with high flexibility.

[0056] 4) The receiver's sliding structure is applied to the receiver, and then the entire unit is slid and hoisted. This overall sliding hoisting scheme reduces high-altitude work procedures and lowers the risk of falls. The time spent working on the tower is significantly reduced, as is the overlap with work at the tower base. The overall sliding hoisting construction scheme saves 220 days compared to traditional high-altitude assembly (a time advantage), significantly reducing the use of large lifting equipment and labor costs. All components are lifted and assembled on the ground, reducing a large amount of high-altitude work and manpower. The number of construction personnel is reduced by 3900 person-days compared to conventional methods, resulting in a correspondingly significant cost reduction and decreased construction difficulty (a cost advantage).

[0069] Various embodiments will now be described in detail, one or more examples of which are illustrated in the figures. The examples are provided for illustrative purposes and are not intended to be limiting. For example, features illustrated or described as part of one embodiment can be used in or combined with any other embodiment to produce yet another embodiment. The invention is intended to include such modifications and variations.

[0070] In the following description of the accompanying drawings, the same reference numerals indicate the same or similar parts. Generally, only the differences between individual embodiments will be described. Unless otherwise expressly indicated, the description of parts or aspects of one embodiment can also be applied to corresponding parts or aspects of another embodiment.

[0071] like Figure 1 As shown, in order to solve one or more technical problems in the prior art, this embodiment provides a heat absorber sliding device, including:

[0072] The receiver consists of a sliding track 1 (composed of two parallel rails), a supporting ring beam 4, multiple sliding shoes 2, a propulsion system 3, and a computer control system. (See also...) Figure 2 The absorber sliding track consists of two parallel slide rails, with 19 slide rails on each line. Each slide rail is 5.4m long, and the total length of a single track is 102.9m.

[0073] See Figure 3 The sliding track 1 is fixed to the ground by a limit clamp. See also Figure 4 The limit clip is fixed to the concrete foundation by bolts. Figure 5 The image shows the fixing details of the sliding track, with 160 Type I limit clamps. The limit clamps are connected to the concrete raft slab using 8.8 grade M20*50mm bolts and washers. A standard sleeve is located beneath the bolt. Reinforcing steel is embedded within the concrete foundation where the limit clamps are located. The standard sleeve, model FISCHER EA II M20 LT80, ensures a tighter connection between the bolt and the concrete foundation. The bolts are grade 8.8. Once removed, plastic caps must be installed. The bolt holes in the CLS plate have a diameter of 24mm and a depth of 85mm. The limit clamps are made of S355J0EN10025 material. Each limit clamp weighs 12.6kg. Before use, the limit clamps undergo non-destructive testing, with 100% visual inspection and 30% LP or magnetic particle testing.

[0074] like Figure 6 As shown, the support ring beam 4 is located at the bottom of the receiver and is used to support the entire receiver. In this embodiment, the total weight of the ring beam is 1846.7 mt. The center is the location of the center of gravity under no wind load and no braking. If there is wind load and braking occurs, the center of the support ring beam will change. The detailed calculation and determination method of the center of gravity will be introduced later.

[0075] like Figure 7As shown, there are four sliding shoes 2, symmetrically distributed on the support ring beam. Each sliding shoe 2 includes a floating device 21, one central main jack 22, and two auxiliary jacks (not shown as connecting accessories in this embodiment). The bottom of the floating device 21 is made of stainless steel and is installed in the sliding track 1. The sliding track 1 is equipped with PTFE or high-density polyethylene pads. The central main jack 22 is installed on the main body of the floating device 21. The weight of the central main jack 22 is SWL = 600 tons. In this embodiment, the floating device is a floating plate. The bottom floating plate of the sliding device is installed in the sliding track. The bottom floating plate is used to hoist the main oil top until the flange above the main oil top is close to the flange on the lower surface of the receiver support ring beam. The sliding device is adjusted so that the flange above the main oil top is directly opposite the flange on the bottom plate of the support ring beam. The connection is made using M30×140mm bolts and finally tightened.

[0076] According to another aspect of the invention, the propulsion system 3 has multiple components, each equipped with a power unit, a brake, and a control box. The power unit provides sufficient pressure and flow to achieve the designed gliding speed. The brake is used for braking the propulsion system 3. The control box includes a control box housing, sensors, hydraulic valves, and connectors. The hydraulic valves are connected to the housing via connectors. The sensors are placed inside the control box housing and are used to collect the following data during the operation of the receiver gliding device: main cylinder pressure load, main cylinder stroke, push / pull cylinder pressure or load, push / pull cylinder stroke, and lateral movement system. The sensors transmit the data to a computer system via cables or wirelessly to control and monitor the load, vertical and horizontal displacement, actual center of gravity, and / or propulsion stroke of the receiver gliding device.

[0077] How to use and how to work the heat absorber sliding device:

[0078] I. Installation of Heat Absorber Sliding Rail 1

[0079] 1. Inspection and confirmation conditions before track installation:

[0080] 1. The foundation for the sliding track has been completed and passed inspection.

[0081] 2. The track foundation markings have been completed and have passed inspection.

[0082] 3. The quantity of track materials and accessories has been counted and the quality has been inspected and approved.

[0083] 4. Track load-bearing calculation sheet. The track foundation and track are designed according to the sinker sliding requirements. The foundation has been inspected and accepted by the general contractor and other units during the handover. There is no need to conduct an endurance test on the track with on-site counterweight.

[0084] 2. Installation and Standards of Heat Absorber Sliding Rail 1

[0085] 1) Track composition: The absorber sliding track consists of two parallel slide rails. Each line has 19 slide rails, each with a length of 5.4m, and the total length of a single track is 102.9m.

[0086] 2) Track installation method: The track is directly laid on the concrete foundation surface using a tower crane. After alignment and acceptance, each track is fixed to the foundation using four clips and bolts.

[0087] 3) Sliding track parameter standards,

[0088] Number of slide rails per line, length 5.4 meters: 19; Track spacing: 16098 ± 1.5 mm

[0089] Maximum cross slope: ±0.1% Maximum longitudinal slope: ±0.5%

[0090] Maximum longitudinal clearance between the two slide rails: 10mm

[0091] Maximum planar deviation between the two slide rails: 1mm

[0092] Maximum vertical clearance between the two slide rails: 1mm

[0093] The track foundation is designed based on the load calculation during the sinker's sliding process. The load on the track is not checked on site. Only the dimensions of the foundation are inspected before the track is installed. The track dimensions are inspected with reference to the parameters above.

[0094] II. Installation of the skid shoe

[0095] The bottom floating plate of the sliding device is installed in the sliding track. The bottom floating plate is hoisted to the main oil top until the flange above the main oil top is close to the flange on the lower surface of the receiver ring beam. The sliding device is adjusted so that the flange of the main oil top is aligned with the flange of the bottom plate of the supporting ring beam. The connection is made using M30×140mm bolts and finally tightened.

[0096] III. Sliding process of the absorber sliding device

[0097] After confirming that the sliding device is installed correctly, the central main jack 22 can be raised until it contacts the flange of the supporting ring beam 4. The four sliding lifting devices are operated by one control system to ensure that the hydraulic lifting devices operate simultaneously, raising the heat absorber horizontally.

[0098] 1. Start the lifting device to lift the support ring beam and the heat absorber together. The load of the hydraulic lifting device will increase by 20% at a time until it reaches 100% load. Carefully check the deformation of the track concrete foundation, track, and support ring beam, as well as the bolt connection status between the ring beam and the lifting device, and make relevant records.

[0099] 2. Start the four hydraulic lifting devices to simultaneously lift the support ring beam and the absorber by 200mm. Then start the sliding device, with each sliding distance being 600mm. During the sliding process, use the computer control system to monitor whether the stroke and load of each sliding device are consistent. The load of the sliding device should be basically consistent within one stroke, and the deviation should not exceed 5%. After each stroke of sliding is completed, adjust the load and stroke of the pushing device through the computer control system to ensure that the four sliding devices move synchronously. Repeat the above operation until the absorber slides to the position directly below the tower.

[0100] IV. Relevant Calculations During the Sliding Process

[0101] 1. Sliding shoe calculation

[0102] Calculations under the following conditions during the slip process: maximum wind speed of 10 m / s, 10% increase in absorber weight, and 0.5 m shift in center of gravity:

[0103] 1) Absorber sliding geometry

[0104] 2) Calculation of wind force and braking force

[0105] A. Wind calculation

[0106] This heat absorber can be viewed as a cylinder composed of 16 polygons, with a wind-receiving surface of 21 × 35 = 735 m². 2 The drag coefficient for this shape is 1.3;

[0107] Assuming the maximum permissible wind speed is 10 m / s, the wind force can be calculated using the following formula:

[0108] The MSR (heat absorber) can be considered as a multi-faceted cylindrical column with 16 faces, and its wind-receiving area is approximately 21 * 35 = 735 m². 2 The drag coefficient for this shape is 1.3, according to the table.

[0109] Assuming the maximum permissible wind speed at the top of the tower is 10 m / s, the basic wind pressure is:

[0110] P W =C 2 / 16=6.25kgf / m 2 Therefore, the total wind force with a maximum permissible wind speed and a safety factor of 1.5 is: H1,d = 0.00625 × 1.3 × 735 × 1.5 = 9 mT

[0111] B. Braking force calculation

[0112] The coefficient of friction of the polyethylene plate inside the sliding track is 0.05. Assuming a safety factor that increases the friction by a factor of 1.5, equivalent to a 10% increase in the weight of the heat absorber, the braking force is:

[0113] H2,d=0.05×1.5×1786.4=134mT

[0114] C. Total forces on overturning and eccentricity under the action of wind and braking force:

[0115] H = H1,d + H2,d = 9 + 134 = 143mT

[0116] Horizontal torque: MT,d = 143 × 19.814 = 2833.4m 2 T

[0117] The increase in eccentricity under the action of this force:

[0118] e=MT,d / WT,d=2833.4 / 1786.4=1.5m,

[0119] The force distribution of the receiver changes after eccentricity of 1.5m:

[0120] Redistribution coefficient for the right vertical line: CD = 9864 / 16098 = 0.613

[0121] Redistribution coefficient for the upper horizontal line: BC = 8298 / 16098 = 0.515

[0122] The redistribution coefficient for the left longitudinal line: AB = 1 - 0.613 = 0.387

[0123] Lower lateral line redistribution coefficient: AD = 1 - 0.515 = 0.485 Force on each slip shoe: R A =0.387×0.485×1786.4=335.3mT

[0124] R B =0.387×0.515×1786.4=356.0mT

[0125] R C =0.613×0.515×1786.4=564.0mT

[0126] R D =0.613×0.485×1786.4=531.1mT

[0127] The maximum force on the skid shoe is 564mT, which is less than the rated load of 600mT, so it is qualified.

[0128] 2. The track foundation and track are designed according to the relevant parameters of the absorber sliding. In this embodiment, it is not necessary to calculate the track. Only after the foundation and track are completed, the acceptance is carried out according to the standard parameters of the track.

[0129] V. Monitoring measures for the slip process:

[0130] 1. Monitor the stroke and load of the skid shoes using the computer control system to ensure that the four skid shoes move synchronously;

[0131] 2. During the sliding process, the verticality of the receiver body is monitored in real time using a theodolite;

[0132] 3. During the sliding process, use a high-precision level to measure the real-time settlement of the sliding foundation to ensure sliding safety. If the settlement exceeds the overturning safety standard, it should be reported to the relevant design party for an assessment of the actual situation on site.

[0133] 4. Monitor the wind speed in real time during the sliding process. Stop sliding if the wind speed exceeds the standard requirements.

[0134] While the foregoing describes embodiments of the present invention, other and further embodiments of the present invention may be devised without departing from the basic scope of the present invention, the scope of which is defined by the following claims.

[0135] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention.
