Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a standard section for a secondary reflection tower that is easy to assemble. Background Art

[0002] Molten salt tower solar thermal power generation technology uses salt as a heat absorption and storage medium. It utilizes solar energy collected by a large-scale heliostat field to heat and store the molten salt. The high-temperature, high-pressure steam generated by the heat exchange between the molten salt and water is then used to drive a steam turbine generator set to generate electricity according to the grid's dispatch instructions. This technology primarily involves installing multiple mirrors around the collector to reflect and focus sunlight onto the top of the collector tower, heating the molten salt and thus generating electricity. In this power generation technology, the equipment used for solar energy collection is primarily a secondary emission tower module. During the construction of the secondary emission tower module, standard sections are constructed in conjunction with the weekly test to facilitate the lifting of the secondary emission tower module. However, the existing standard sections have the following shortcomings in actual use:

[0003] 1. The existing method of connecting standard sections is mainly to fix them by bolts. This connection method is inconvenient to install, and the bolts are prone to loosening during long-term use, resulting in low overall safety of the standard section.

[0004] 2. Existing horizontal standard sections are reinforced with X-frames to improve overall stability. However, because the length of the X-frames is fixed, it is inconvenient to adjust the size of the standard section frames according to the needs of the building. Even if the size is forcibly adjusted, the X-frames will also need to be adjusted accordingly, which is troublesome and increases construction costs.

[0005] Therefore, it is necessary to improve the existing technology to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a standard section for a secondary reflection tower that is easy to assemble and has quick and convenient installation, high stability and easy overall adjustment, thereby solving the problems of existing standard sections that are inconvenient to install, poor stability and inconvenient adjustment of the standard section frame in actual use.

[0007] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The present invention provides a standard section for a secondary reflection tower that is easy to assemble, comprising a standard section body. The top surface of the standard section body is uniformly provided with a plurality of open slots along the circumferential direction. A first protrusion is provided at the upper end of the outer wall of the standard section body between two adjacent open slots. A rotating column is fixedly connected to the upper end of the inner side wall of the open slot. A locking mechanism is provided in each open slot.

[0009] The locking mechanism is mainly composed of a positioning rod and a grabbing rod integrally formed and arranged on the outer side of the top surface of the positioning rod. A through groove with a semicircular upper end is provided in the vertical direction at the upper end of the positioning rod. A sleeve is provided in the through groove and the sleeve is slidably sleeved on the rotating column. The sleeve and the inner bottom surface of the through groove are also fixedly connected by a return spring.

[0010] A stop plate is provided on one side surface of the lower end of the positioning rod and extends in the axial direction of the standard section body, and an insert rod for engaging with the stop plate is integrally formed on the bottom surface of the standard section body;

[0011] A notch is provided on the side of the upper end of the grabbing rod close to the standard section body, and a hook is provided on one side surface of the grabbing rod at the notch position; a buckle is provided on the outer side wall of the lower end of the standard section body, and a buckle groove with a trapezoidal cross-section is provided along the circumferential direction on the top surface of the buckle for buckling with the buckle.

[0012] Furthermore, a plurality of second protrusions are evenly distributed along the circumferential direction on the bottom side wall of the standard section body, and a positioning groove is formed between two adjacent second protrusions. The plurality of first protrusions and the plurality of second protrusions are aligned one by one, and the plurality of open grooves and the plurality of positioning grooves are aligned one by one; a plug-in column is provided on the bottom surface of the second protrusion, which is gap-matched with the through groove on the second protrusion.

[0013] Furthermore, a guide ring is circumferentially provided on the outer wall of the middle portion of the sleeve, and a guide groove that is gap-matched with the guide ring is provided on the inner wall of the through groove.

[0014] Furthermore, a positioning column is provided on the bottom surface of the positioning rod, and a positioning hole is provided on the inner bottom surface of the open groove to fit with the positioning column in a clearance.

[0015] Furthermore, a first reinforcement ring is fixedly connected to the outer side wall of the standard section body at the position of the opening groove below the first protrusion, and a plurality of first reinforcement ribs for connecting the first reinforcement ring and the standard section body are evenly distributed along the circumferential direction below the first reinforcement ring.

[0016] Furthermore, a plurality of second reinforcing ribs for connecting the buckle and the standard section body are evenly distributed along the circumferential direction below the buckle.

[0017] Furthermore, four guide rods parallel to the axis of the standard section body are circumferentially provided on the outer side wall of the standard section body between the buckle ring and the first reinforcement ring, and the guide rods are provided with convex grooves with two ends open.

[0018] Furthermore, at least two standard section bodies cooperate in the vertical direction to form a standard section group, and four standard section groups form a rectangular standard section frame on the same horizontal plane, and an X-shaped adjustment frame is provided between two adjacent standard section groups;

[0019] The X-shaped adjustment frame is mainly composed of two cross-shaped support plates, and the middle parts of the two support plates are rotatably connected by a rotating pin; convex columns are fixedly connected to both ends of the same side of the support plates, and the convex columns are used to cooperate with the fixed ears on the outer wall of the I-shaped block;

[0020] The I-shaped block is loosely fitted in the convex groove, and locking bolts are screwed on the I-shaped blocks on both sides of the fixing ear, with one end of the locking bolt abutting against the outer wall of the guide rod;

[0021] A through hole is provided in the nut on one end of the locking bolt, a limit rod is slidably inserted in the through hole, and both ends of the limit rod are welded to the I-shaped block.

[0022] Furthermore, the convex columns on the two cross-arranged support plates are arranged on relatively far sides of the two support plates (201).

[0023] Furthermore, the two I-shaped blocks of the X-shaped adjustment frame on the same standard section group are fitted in two adjacent guide rods, and each guide rod is fitted with at least one I-shaped block.

[0024] The present invention has the following beneficial effects:

[0025] When the two standard section bodies are assembled in the vertical direction, the positioning rod will rotate with the rotating column as the axis under the action of squeezing, so that the entire locking mechanism is arranged in the vertical direction, and the hooks at the upper ends of the multiple grabbing rods are engaged with the buckle above the upper standard section body. As the insertion rod continues to be inserted, the anti-plate will move downward. Under the action of the anti-plate moving downward, the entire locking mechanism moves downward. At this time, the hooks are engaged in the buckle grooves to achieve locking between the two standard section bodies. Because under the action of the standard section body's own gravity, as the standard section body continues to increase, the hooks will be firmly engaged in the buckle grooves to prevent the hooks from automatically falling off. When the standard section body needs to be dismantled, the standard section body is moved upward. Under the action of the return spring, the locking mechanism below moves upward to realize the expansion of the locking mechanism and release the locking state of the standard section body. This arrangement makes the assembly and disassembly of the two standard section bodies very convenient and can effectively prevent the loosening between the two standard section bodies.

[0026] 2. The sliding arrangement of the I-shaped block in the convex groove and the rotation of the two support plates in the X-shaped adjustment frame with the rotating pin as the axis can adjust the distance between the two horizontal standard section groups, thereby facilitating size adjustment according to actual needs. After the adjustment is completed, the staff uses the locking bolt to achieve the initial fixation between the I-shaped block and the guide rod, and then inserts the limit rod into the through hole. By welding between the limit rod and the I-shaped block, the self-loosening of the locking bolt can be avoided. This arrangement can achieve size adjustment of the standard section frame, and the overall applicability is stronger. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0042] See also Figure 3-7 As shown, the present invention is a standard section for a secondary reflection tower that is easy to assemble, comprising a standard section body 1. The top surface of the standard section body 1 is uniformly provided with a plurality of opening slots 107 along the circumferential direction. A first protrusion 108 is provided at the upper end of the outer wall of the standard section body 1 between two adjacent opening slots 107. A rotating column 106 is fixedly connected to the upper end of the inner wall of the opening slot 107. A locking mechanism 4 is provided in each opening slot 107.

[0043] A first reinforcement ring 104 is fixedly connected to the outer wall of the standard section body 1 at the position of the opening groove 107 below the first protrusion 108, and a plurality of first reinforcement ribs 1041 for connecting the first reinforcement ring 104 and the standard section body 1 are evenly distributed along the circumference below the first reinforcement ring 104. The cooperation between the first reinforcement ring 104 and the first reinforcement ribs 1041 can improve the strength of the position of the opening groove 107 and increase stability;

[0044] A plurality of second protrusions 103 are uniformly distributed along the circumferential direction on the bottom side wall of the standard section body 1, and a positioning groove 1032 is formed between two adjacent second protrusions 103. The plurality of first protrusions 108 and the plurality of second protrusions 103 are aligned one by one, and the plurality of opening grooves 107 and the plurality of positioning grooves 1032 are aligned one by one. This arrangement can avoid the second protrusions 103 from blocking the locking mechanism 4 when the two standard section bodies 1 are matched; a plug post 1031 is provided on the bottom surface of the second protrusion 103, which is clearance-matched with the through groove 1081 on the second protrusion 103. The cooperation between the plug post 1031 and the through groove 1081 can realize the preliminary positioning of the two standard section bodies 1 on the one hand, and can also assist in the stability of the two standard section bodies 1 when they are matched;

[0045] When the above arrangement is in use, the plug post 1031 and the through slot 1081 cooperate to achieve a preliminary connection between the two standard section bodies 1 , and then the locking mechanism 4 locks and fixes the two assembled standard section bodies 1 .

[0046] See also Figure 3-4 As shown in Figures 6-8 , the locking mechanism 4 is mainly composed of a positioning rod 402 and a grabbing rod 401 integrally formed and arranged on the outer side of the top surface of the positioning rod 402. A through groove 4023 with a semicircular upper end is provided in the vertical direction at the upper end of the positioning rod 402. A sleeve 4022 is provided in the through groove 4023, and the sleeve 4022 is slidably sleeved on the rotating column 106. The sleeve 4022 and the inner bottom surface of the through groove 4023 are also fixedly connected by a reset spring 4025. The reset spring 4025 can realize the automatic reset of the sleeve 4022 when in use.

[0047] A guide ring 4026 is provided on the circumferential outer wall of the central portion of the sleeve 4022. A guide groove 4024 is provided on the inner wall of the through-groove 4023 to provide clearance fit with the guide ring 4026. This arrangement serves to limit and guide the sleeve 4022 as it moves.

[0048] A stop plate 4021 is provided on one side of the lower end of the positioning rod 402, extending in the axial direction of the standard section body 1. At the same time, an insertion rod 105 for engaging with the stop plate 4021 is integrally formed on the bottom surface of the standard section body 1. The stop plate 4021 can play a role in abutting the lower end of the insertion rod 105.

[0049] A positioning post 4027 is provided on the bottom surface of the positioning rod 402, and a positioning hole 1071 is provided on the inner bottom surface of the opening slot 107 to fit the positioning post 4027. This arrangement can achieve the limited fixation of the positioning rod 402;

[0050] When the above arrangement is in use, when the two standard section bodies 1 are mated, the upper insertion rod 105 is inserted into the top surface of the lower standard section body 1. As the insertion proceeds, due to the abutment of the abutment plate 4021, the positioning rod 402 will rotate with the rotating column 106 as the axis. After the positioning rod 402 is rotated to be parallel to the opening groove 107, as the insertion rod 105 continues to be pressed down, the sleeve 4022 slides in the through groove 4023. At this time, the reset spring 4025 is in a stretched state. When the staff pulls up the insertion rod 105, the sleeve 4022 returns to the specified position due to the reset action of the reset spring 4025. Then the positioning rod 402 rotates with the rotating column 106 as the axis, and the locking mechanism 4 is expanded and loses the locking effect.

[0051] See also Figure 3-5 As shown in Figures 7-8, a notch 4012 is provided on one side of the upper end of the grabbing rod 401 close to the standard section body 1, and a hook 4011 is provided on one side of the grabbing rod 401 at the position of the notch 4012; a buckle 102 is provided on the outer wall of the lower end of the standard section body 1, and a buckle groove 1022 with a trapezoidal cross-section is provided along the circumferential direction on the top surface of the buckle 102 for buckling with the hook 4011;

[0052] A plurality of second reinforcing ribs 1021 are evenly distributed along the circumference below the buckle 102 for connecting the buckle 102 to the standard section body 1. The provision of the second reinforcing ribs 1021 can improve the stability of the buckle 102.

[0053] When the above arrangement is in use, as the insertion rod 105 moves downward to press the abutment plate 4021, the grabbing rod 401 will also drive the hook 4011 to move downward due to the linkage. When the hook 4011 moves downward, it will be engaged in the buckle groove 1022 to achieve the locking of the locking mechanism 4.

[0054] See also Figure 1 、 2 As shown in , 4, 5 and 9-11, four guide rods 101 parallel to the axis of the standard section body 1 are circumferentially provided on the outer side wall of the standard section body 1 between the buckle 102 and the first reinforcement ring 104, and a convex groove 1011 with open ends is provided on the guide rod 101. The convex groove 1011 is open at both ends to facilitate the fitting and installation between the I-shaped block 3 and the guide rod 101;

[0055] At least two standard section bodies 1 are matched in the vertical direction to form a standard section group. Four standard section groups form a rectangular standard section frame on the same horizontal plane, and an X-shaped adjustment frame 2 is provided between two adjacent standard section groups.

[0056] The X-shaped adjustment frame 2 is mainly composed of two cross-shaped support plates 201, and the middle parts of the two support plates 201 are rotatably connected by a rotating pin 202. This arrangement can realize the relative angle adjustment and rotation of the two support plates 201; convex columns 203 are fixedly connected to both ends of the same side of the support plate 201. The convex columns 203 are used to fit with the fixing ears 302 on the outer wall of the I-shaped block 3. This arrangement can realize the rotation of the convex columns 203 relative to the fixing ears 302;

[0057] The I-shaped block 3 is loosely fitted in the convex groove 1011, and locking bolts 301 are screwed on the I-shaped block 3 on both sides of the fixing ears 302. One end of the locking bolt 301 abuts against the outer wall of the guide rod 101. This arrangement can achieve positioning and fixation between the I-shaped block 3 and the guide rod 101 when the locking bolt 301 is tightened.

[0058] A through hole 304 is provided in the nut on one end of the locking bolt 301. A limit rod 303 is slidably inserted into the through hole 304. Both ends of the limit rod 303 are welded to the I-shaped block 3. The setting of the limit rod 303 can position the locking bolt 301 and prevent the locking bolt 301 from loosening due to gravity.

[0059] The convex columns 203 on the two cross-arranged support plates 201 are arranged on relatively far sides of the two support plates 201. This arrangement can prevent the two support plates 201 from blocking each other.

[0060] The two I-shaped blocks 3 of the X-shaped adjustment frame 2 on the same standard section group are fitted in two adjacent guide rods 101, and each guide rod 101 is fitted with at least one I-shaped block 3;

[0061] When the above arrangement is in use, the staff first fits the I-shaped blocks 3 at both ends of the X-shaped adjustment frame 2 in the convex grooves 1011 as needed. As the distance between the two standard section groups is adjusted, the support plates 201 in the X-shaped adjustment frame 2 are rotated to adjust the relative angles. During the adjustment process, the I-shaped blocks 3 will also slide in the convex grooves 1011. After the adjustment is completed, the staff can achieve the preliminary fixation between the I-shaped block 3 and the guide rod 101 by tightening the locking bolts 301. Then the staff inserts the limit rod 303 into the through hole 304 and welds the two ends of the limit rod 303 to the I-shaped block 3 by welding to achieve the final fixation between the I-shaped block 3 and the guide rod 101. When the standard section frame needs to be disassembled, it is only necessary to cut off the limit rod 303 and then loosen the locking bolts 301 to achieve the disassembly between the I-shaped block 3 and the guide rod 101.

[0062] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
