Description

Technical Field

[0001] The present invention relates to the technical field of enclosures, and particularly to a precast coping for a modular green enclosure of a substation. Background Art

[0002] With the development of social economy and the acceleration of urbanization, the construction demand for power equipment is increasing day by day. As a key link in power transmission and distribution, the safety and stability of substations are particularly important. The enclosures of substations not only play a role in protecting the safety of equipment and personnel, but also need to have multiple functions such as earthquake resistance, wind resistance, and waterproofing. Traditional substation enclosures mostly use on-site cast-in-place concrete construction. Although this method has a relatively low cost, it has disadvantages such as a long construction period, large environmental pollution, and difficult quality assurance, and it is difficult to meet the requirements of modern green buildings. In order to improve the construction efficiency and quality of precast copings for substation enclosures, the technology of modular enclosure precast copings has emerged. The modular enclosure precast copings prefabricate each component in the factory and then transport them to the site for assembly, which has the advantages of fast construction speed, controllable quality, and environmental friendliness.

[0003] Patent Application No. CN201420058427.2 discloses a precast concrete coping for a substation enclosure. The coping is precast from concrete and steel bars, and the cross-section is in a single-slope shape, with the inner side of the wall being high and the outer side of the wall being low, which is convenient for draining the rainwater on the wall top to the outside of the wall. Drip grooves are provided on both sides of the bottom, and steel bar hooks are provided at the ends. The precast concrete coping is bonded to the enclosure through cement mortar. A gap is left between the copings and filled with asphalt hemp rope, and the surface of the joint is sealed with silicone weather-resistant glue. After installation, the hooks are cut off and zinc spraying anti-corrosion treatment is carried out. The design is simple, the quality is reliable, and it does not affect the construction environment. It can effectively solve the problems caused by uneven settlement of the foundation or temperature stress, and the cost is relatively low.

[0004] In the above patent, the precast concrete coping of the enclosure is connected to the wall top through cement mortar. The connection is single and not firm enough. Dust will be generated during the on-site mixing of cement mortar, which will harm the health of construction workers and cause environmental pollution. The precast concrete coping connected by cement mortar cannot be reused after being demolished. In addition, the step of cutting off the hooks after installation makes the construction process more complicated and wastes resources. In addition, traditional precast enclosures still have deficiencies in safety monitoring and maintenance, and it is difficult to detect and warn potential safety hazards in a timely manner. Summary of the Invention

[0010] Preferably, two tightening barbs are symmetrically arranged at the end of the spring latch rod body, and a plurality of anchoring rings are arranged, and the anchoring rings are in an annular structure.

[0011] Preferably, the prefabricated capping of the modular green fence of the substation also includes a tilt adjustment component, which includes a pressure sensor, an air hole and an air pump, the air pump is provided with an inflation main pipeline, and a plurality of inflation hoses are connected to the inflation main pipeline, the pressure sensor is fixedly installed inside the spring latch cylinder, an air hole is provided at one end of the spring latch cylinder away from the tightening barb, and the inflation hose is connected to the spring latch cylinder through the air hole.

[0012] Preferably, the prefabricated capping of the modular green fence of the substation also includes a recovery and disassembly mechanism, which includes a tilt adjustment component and a weak area, which is an annular groove arranged in the inner wall of the spring pin cylinder. The number of the weak areas is the same as that of the anchor ring, and the corresponding weak areas are arranged on the inner wall of the spring pin cylinder on the side of the anchor ring away from the tightening barb.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The prefabricated capping of a modular green fence of a substation of the present invention has a built-in dual-axis tilt sensor, which can monitor the settlement and tilt angle data of the fence in real time, timely warn of potential safety risks of the fence, and ensure the safety and stability of the fence.

[0015] 2. In the present invention, the tenon at the bottom of the precast concrete capping is connected with the groove of the wall at the top of the wall to prevent the precast concrete capping from falling out of one side of the wall, so that the connection between the precast concrete capping and the wall can be more firmly established. In addition, the precast concrete capping is engaged with the concave groove of the wall through a hidden spring pin, so that the connection between the precast concrete capping and the wall is more stable and not easy to fall off.

Considering the wear of the hidden spring latch, a new hidden spring latch can be installed when the precast concrete cap is reused on the wall to achieve a stable connection between the precast concrete cap and the wall.

[0018] 5. The present invention is based on a removal method in which gas is inflated into the inner cavity of the spring latch cylinder to rupture the weak area. When the weak area is ruptured, a larger airflow will also impact the connection between the hidden spring latch and the precast concrete top, causing the connection to be further loosened and prevent adhesion. It can also blow away blockages such as concrete particles at the connection between the precast concrete top and the hidden spring latch, thereby avoiding affecting the removal of the hidden spring latch.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0037] Example 1: Figure 1-Figure 9 As shown, the present embodiment provides a modular green wall prefabricated capping for a substation, comprising a plurality of precast concrete cappings 1 arranged along the top of the wall 2, a gap between two adjacent precast concrete cappings 1 being filled with silicone weather-resistant glue 12, a wall groove 6 being arranged at the top of the wall 2 along the length direction of the wall 2, a wall concave cut groove 7 being arranged at the inside and outside of the wall 2 along the length direction of the wall 2, a tenon 5 matching the wall groove 6 being arranged in the middle of the bottom of the precast concrete capping 1, capping block grooves 10 being arranged on both sides of the bottom of the precast concrete capping 1, hidden spring latches 4 being arranged at the same height as the capping block grooves 10 on both sides of the bottom of the precast concrete capping 1, a hollow structure 9 being arranged inside the precast concrete capping 1, a dual-axis inclination sensor 3 being arranged in the hollow structure 9, and continuous V-shaped drip line grooves 8 being arranged on both sides of the bottom of the precast concrete capping 1.

[0038] The precast concrete capping 1 is made of all-recycled concrete aggregate, mineral powder, bamboo fiber, foam and cement. The use of these materials has greatly improved the low-carbon, environmental protection and durability of the precast concrete capping 1; the use of recycled concrete aggregate can reduce the demand for waste landfill and reduce resource consumption, thereby saving economic costs and environmental burdens. The use of recycled concrete aggregate and mineral powder can maintain or even improve the mechanical properties of the precast concrete capping 1. The precast concrete capping 1 made of recycled concrete aggregate performs well in compression resistance, bending resistance and wear resistance, and meets industrial standards. In addition, the addition of bamboo fiber can improve the toughness, crack resistance and durability of the precast concrete capping 1. Therefore, the precast concrete capping 1 of the present invention is not only green and environmentally friendly, but also has good mechanical properties and durability, and is economically feasible and suitable for actual engineering applications.

[0039] The hidden spring latch 4 is made of stainless steel. The hidden spring latch 4 is arranged at both ends of the precast concrete top 1, two on the left and two on the front and back. The hidden spring latch 4 includes a spring latch cylinder 17 and a spring latch rod 13. The spring latch cylinder 17 of the hidden spring latch 4 is pre-buried in the precast concrete top 1, and a plurality of anchoring rings 15 fixedly arranged on the periphery of the spring latch cylinder 17 are used to strengthen the anchoring force of the hidden spring latch 4 in the precast concrete top 1. The spring latch cylinder 17 is provided with a spring latch rod 13, and the spring latch rod 13 can slide back and forth through a spring 14. One end of the spring 14 is fixedly connected to one end of the spring latch rod 13 that is movably extended into the spring latch cylinder 17, and the other end of the spring 14 is fixedly connected to the inner bottom surface of the spring latch cylinder 17. The end of the spring latch rod 13 located outside the spring latch cylinder 17 is fixedly provided with a tightening barb 16, and the tightening barb 16 is arranged in the concave groove of the fence. 7, the precast concrete top 1 is connected to the fence 2 by the elastic force of the spring 14 and the mechanical bite force of the tightening barb 16. When the spring 14 lifts the spring latch rod 13 to slide away from the spring latch cylinder 17, the tightening barb 16 engages with the concave groove 7 of the fence. When the precast concrete top 1 needs to be disassembled, the spring latch rod 13 is rotated 90°, and the spring latch rod 13 is pressed to slide back to the spring latch cylinder 17, so that the precast concrete top 1 can be disassembled. The precast concrete capping block 1 can be separated from the surrounding wall 2, thereby realizing the disassembly of the precast concrete capping block 1. In addition, the connection between the precast concrete capping block 1 and the surrounding wall 2 is also achieved through the tenon 5 at the bottom of the precast concrete capping block 1 and the surrounding wall groove 6 at the top of the surrounding wall 2, and the rubber tenon strip 11 is used to clamp the capping block groove 10 and the surrounding wall concave groove 7, so that the connection is firm and detachable; wherein, one end of the rubber tenon strip 11 is clamped in the capping block groove 10, and the other end of the rubber tenon strip 11 is clamped in the surrounding wall concave groove 7.

[0040] The present invention provides a hidden spring latch 4, so that when the precast concrete cap 1 is affected by strong wind or other stress, the hidden spring latch 4 can relieve the stress, play a buffering purpose, and assist the precast concrete cap 1 to reset and maintain a horizontal state, thereby preventing the precast concrete cap 1 from falling out of one side of the wall 2. The dual-axis inclination sensor 3 can collect the settlement and inclination angle data of the wall 2 in real time, and timely warn of potential safety risks of the wall 2.

[0041] Example 2: Figure 10-11As shown, this embodiment, based on the prefabricated capping structure of the modular green fence of the substation in Example 1, also includes an inclination adjustment component, the inclination adjustment component includes a pressure sensor 21, an air hole 22 and an air pump 18, the air pump 18 is provided with an inflation main pipe 19, and the inflation main pipe 19 is connected to a plurality of inflation hoses 20, the pressure sensor 21 is fixedly mounted inside the spring latch cylinder 17, the end of the spring latch cylinder 17 away from the tightening barb 16 is provided with an air hole 22, the air hole 22 connects the inside and outside of the spring latch cylinder 17, and the air hole 22 is connected to the corresponding inflation hose 20.

[0042] When the precast concrete top 1 tilts, the spring latch rods 13 on both sides of the fence 2 have different expansion and contraction amounts in the spring latch cylinder 17, either compressing the inner cavity of the spring latch cylinder 17 or expanding the inner cavity of the spring latch cylinder 17, which causes the pressures monitored by the pressure sensors 21 at the corresponding positions to be different. If the pressure sensor 21 on one side of the fence 2 detects that the pressure inside the spring latch cylinder 17 is greater than the pressure inside the spring latch cylinder 17 on the other side of the fence 2, it proves that the inner cavity of the spring latch cylinder 17 with large pressure is compressed, and the precast concrete top 1 tilts toward the spring latch cylinder 17 at this point. At this time, the air pump 18 is started to inflate the inner cavity of the spring latch cylinder 17 with small pressure through the air pump 18, so that the pressures in the spring latch cylinders 17 on both sides of the fence 2 are equal, so that the precast concrete top 1 returns to a horizontal state. Based on the setting of the inclination angle adjustment component in this embodiment, not only the inclination phenomenon of the precast concrete top 1 can be automatically monitored, but also the inclination angle of the precast concrete top 1 can be adjusted, which is convenient for automatic maintenance and use.

[0043] It should be noted that the air pump 18 and the pressure sensor 21 are connected through a controller, the input end of the controller is connected to the output end of the pressure sensor 21, and the output end of the controller is connected to the input end of the air pump 18. When the pressure sensor 21 monitors the pressure data, the data information is fed back to the controller, and the controller controls the air pump 18 to execute relevant commands. This is a common electrical control structure in the prior art and will not be elaborated here.

[0044] Example 3: Figure 12-14 As shown, this embodiment, based on the prefabricated capping structure of the modular green fence of the substation in Example 2, also includes a recovery and disassembly mechanism, the recovery and disassembly mechanism includes the inclination adjustment component in Example 2, and also includes a weak area 23, the weak area 23 is an annular groove arranged in the inner wall of the spring pin cylinder 17, and there are multiple weak areas 23, and the corresponding weak areas 23 are arranged on the inner wall of the spring pin cylinder 17 on the side of the anchor ring 15 away from the tightening barb 16.

[0045] When the air pressure filled into the inner cavity of the spring latch cylinder 17 by the air pump 18 in the tilt adjustment assembly exceeds the set threshold, the effect of the air pressure will break the wall structure of the spring latch cylinder 17 at the weak area 23 and form a rupture opening 24. At this time, when it is necessary to remove the hidden spring latch 4 from the precast concrete top 1, since the weak area 23 has been broken, the spring latch cylinder 17 can be deformed to a certain extent, making it easy to remove the hidden spring latch 4 from the precast concrete top 1, and it will not be impossible to remove it due to the blocking effect of the anchor ring 15.

[0046] This embodiment is based on the setting of the recycling and disassembly mechanism, so that the hidden spring latch 4 is also easy to remove after the precast concrete top 1 is removed. Considering the wear of the hidden spring latch 4, when the precast concrete top 1 is reused on the wall 2, a new hidden spring latch 4 can be installed to achieve a stable connection between the precast concrete top 1 and the wall 2.

[0047] Furthermore, based on the removal method of inflating gas into the inner cavity of the spring latch cylinder 17 to break the weak area 23, when the weak area 23 is broken, a larger airflow will also impact the connection between the hidden spring latch 4 and the precast concrete pressure top 1, so that the connection is further loosened and will not stick together. It can also blow away blockages such as concrete particles at the connection between the precast concrete pressure top 1 and the hidden spring latch 4, avoiding affecting the removal of the hidden spring latch 4.
