Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power component casting forming, and particularly relates to a steel framework structure and method for power component casting forming for power distribution. BACKGROUND

[0002] At present, a unified prefabricated component product standard, construction and acceptance specification has not been formed in power transmission and distribution engineering, which seriously restricts the popularization and application of prefabricated product production process in power transmission and distribution engineering. The application of prefabricated assembly parts in power transmission and distribution engineering is still in the initial stage. The prefabricated product production process has unique advantages such as high quality, fast efficiency, green environmental protection, etc., and can greatly improve the engineering quality level and shorten the engineering construction period. With the continuous improvement and deepening of the process, standard and facility investment, the prefabricated product production process has broad market prospects in power engineering.

[0003] In the prior art, the power facility foundation structure is mainly based on integral cast-in-place concrete, which has the advantages of integrity, good anti-seepage and waterproof performance, high reliability and good durability. Taking an octagonal well power component as an example, when the octagonal well power component is cast, the concrete raw materials need to be introduced into the cavity of the octagonal mold, and then the concrete raw materials in the cavity are formed to obtain the octagonal well power component. Since the volume of the octagonal well power component itself is large, the concrete is mainly injected into the octagonal steel framework structure during the casting of the octagonal well power component, and then gradually solidified and formed. The formed octagonal well power component needs to be regularly maintained. After the actual casting of the octagonal well power component, quality problems such as middle bulging and local cracking are prone to occur. The root causes of these problems mainly include: 1) the volume of the octagonal steel framework structure itself is large and the height is high. After the concrete is injected into the octagonal steel framework structure, the concrete needs to be vibrated uniformly by using a vibrating member. Since the octagonal steel framework structure is an open structure, it is not convenient for workers to put the vibrating member on the top of the octagonal steel framework structure, and the construction is very inconvenient. The actual use effect of the vibrating member is not good, and the concrete in the octagonal steel framework structure is not uniformly vibrated; 2) the internal concrete of the octagonal steel framework structure will heat during the solidification process, which causes the expansion of the whole blank. Since the octagonal steel framework structure is an integral steel structure, the octagonal steel framework structure tightly binds and fixes the concrete blank, and the middle part of the concrete blank is prone to bulging; 3) when the concrete blank is poured with water on the surface, the heat in the interior of the concrete blank cannot be dissipated in time, which also causes the problems of bulging or local cracking. SUMMARY

[0004] The present application aims to solve the defects in the prior art, and provides a steel framework structure and method for power component casting forming for power distribution.

[0005] To achieve the above object, the technical scheme adopted by the present application is as follows:

[0006] A steel framework structure for power component casting of power distribution, comprising:

[0007] A base;

[0008] A model plate steel framework, the bottom end of which is detachably installed on the base, the inner cavity of which is a model cavity corresponding to the shape of the power component;

[0009] A support net, installed on the top of the model plate steel framework, multiple vibration piece setting work site openings being provided on the support net at intervals;

[0010] A vibration piece guiding and supporting assembly is provided at each vibration piece setting work site opening, each vibration piece guiding and supporting assembly being elastically connected with the support net, one vibration piece being installed on each vibration piece guiding and supporting assembly, each vibration piece being inserted into the vibration piece guiding and supporting assembly and extending into the model cavity, the vibration piece being capable of circumferential swing vibration and axial movement vibration in the vibration piece setting work site opening during vibration construction.

[0011] Multiple first cooling pipe quick couplings are provided on the support net, multiple second cooling pipe quick couplings corresponding to the first cooling pipe quick couplings being provided on the inner side of the base, a cooling pipe being connected between the first cooling pipe quick couplings and the second cooling pipe quick couplings, the cooling pipe being longitudinally installed in the model cavity;

[0012] The first cooling pipe quick couplings are connected with water inlet pipe assemblies, and the second cooling pipe quick couplings are connected with water outlet pipe assemblies.

[0013] The utility model provides a steel skeleton structure of power component casting for power distribution, which comprises a base, a model plate steel skeleton and a support net. When assembled, the base is placed on the ground, the model plate steel skeleton is installed on the base, and the support net is installed on the top of the model plate steel skeleton. The support net is provided with a plurality of vibration piece installation work site openings, and each vibration piece installation work site opening is provided with a vibration piece guide support assembly. The vibration piece guide support assembly is internally installed with a vibration piece. After the model cavity of the model plate steel skeleton is filled with concrete raw materials, the support net on the top of the model plate steel skeleton can provide a construction platform for the constructor. When the constructor uses the vibration piece, the vibration piece is inserted into the vibration piece guide support assembly and extends into the model cavity. Since the number of vibration piece installation work site openings on the support net is multiple, multiple vibration pieces can be simultaneously installed on the support net. When the multiple vibration pieces vibrate the concrete in the model cavity, the uniformity of the concrete filling in the model cavity can be ensured. Since the vibration piece guide support assembly is elastically connected with the support net, the vibration piece can swing at a certain angle in the vibration piece installation work site opening.

After the cooling water passes through the concrete blank, it is finally guided out from the water outlet pipe assembly.

In addition, the terms "first" and "second" are only used to distinguish in the description, and have no special meaning.

[0087] Referring to Figures 1 to 5 The present embodiment provides a steel framework structure for power component casting of power distribution, comprising a base 1, a model plate steel framework 2 detachably mounted on the base 1, and a support net 3 mounted on the top of the model plate steel framework 2, the inner cavity of the model plate steel framework 2 is a model cavity 21, the model cavity 21 corresponds to the shape of the power component, in the present embodiment, the support net 3 is octagonal, and the cross section of the model cavity 21 is also octagonal.

[0088] A plurality of vibration piece installation work site openings 31 are provided on the support net 3, and a vibration piece guide support assembly 4 is elastically mounted at the vibration piece installation work site opening 31 for mounting a vibration piece; each vibration piece is inserted into the vibration piece guide support assembly 4 and extends into the model cavity 21, and the vibration piece can perform circumferential swinging vibration and axial moving vibration in the vibration piece installation work site opening 31 during vibration construction, so as to perform all-around vibration on the concrete and improve the uniformity of concrete filling.

[0089] A plurality of first cooling pipe quick couplings 5 are provided on the support net 3, and a plurality of second cooling pipe quick couplings 6 corresponding to the first cooling pipe quick couplings 5 are provided on the inner side of the base 1, a cooling pipe 7 is connected between the first cooling pipe quick couplings 5 and the second cooling pipe quick couplings 6, and the cooling pipe 7 is longitudinally mounted in the model cavity 21.

[0090] The first cooling pipe quick couplings 5 are connected to a water inlet pipe assembly 8, and the second cooling pipe quick couplings 6 are connected to a water outlet pipe assembly 9.

[0091] The steel framework structure for power component casting of power distribution provided by the present application is composed of a base 1, a model plate steel framework 2, and a support net 3, when the steel framework structure is assembled, the base 1 is placed on the ground, the model plate steel framework 2 is mounted on the base 1, and the support net 3 is fixedly mounted on the top of the model plate steel framework 2 by bolts, a plurality of vibration piece installation work site openings 31 are provided on the support net 3, a vibration piece guide support assembly 4 is provided at the vibration piece installation work site opening 31, after the model cavity 21 of the steel framework structure is injected with concrete raw materials, the support net 3 on the top of the model plate steel framework 2 can provide a construction platform for the constructor, and the constructor uses the vibration piece guide support assembly 4 to install a vibration piece in the vibration piece installation work site opening 31, and the vibration piece can perform circumferential swinging vibration and axial moving vibration in the vibration piece installation work site opening 31 during vibration construction, so as to perform all-around vibration on the concrete and improve the uniformity of concrete filling.

[0092] When the vibration member is a vibration rod, the vibration member is inserted into the guide sleeve 42 and extends into the mold cavity 21. Since the number of vibration member installation sites 31 on the support net 3 is multiple, multiple vibration members can be installed on the support net 3 at the same time. When the multiple vibration members vibrate the concrete in the mold cavity 21, the uniformity of the concrete filling in the mold cavity 21 can be ensured. Since the vibration member guide support assembly 4 and the vibration member installation site 31 of the support net 3 are elastically connected and installed, the vibration member can swing and vibrate in a certain angle of the circumferential direction and move axially in the vibration member installation site 31. When the vibration member is used by the construction personnel, each vibration member can vibrate a region in the mold cavity 21 in all directions, thereby improving the uniformity of the concrete filling.

[0093] The support net 3 is provided with a plurality of first cooling pipe quick connectors 5, and the inner side of the base 1 is provided with a plurality of second cooling pipe quick connectors 6 corresponding to the first cooling pipe quick connectors 5. The first cooling pipe quick connector 5 and the second cooling pipe quick connector 6 are connected by a cooling pipe 7. The cooling pipe 7 is longitudinally installed in the mold cavity 21. Before the mold cavity 21 is filled with concrete, the two ends of the cooling pipe 7 are quickly connected to the first cooling pipe quick connector 5 and the second cooling pipe quick connector 6, respectively. After the mold cavity 21 is filled with concrete and the vibration construction is completed, the concrete blank 100 needs to be cured for a period of time. During the curing process, the water inlet pipe assembly 8 supplies cooling water to each cooling pipe 7. The cooling water passes through the concrete blank 100 and is finally discharged from the water outlet pipe assembly 9. The cooling water flowing in the cooling pipe 7 can take away the heat inside the concrete blank 100, thereby avoiding the problem that the heat inside the concrete blank 100 is too high, causing the surface of the concrete blank 100 to bulge and crack locally.

[0094] Optionally, referring to Figure 6 The vibration member guide support assembly 4 includes a hanging plate 41 fixed to the bottom of the support net 3, a guide sleeve 42 arranged in the vibration member installation site 31, the guide sleeve 42 having two open ends, a support plate 43 arranged on the outer side of the guide sleeve 42, the support plate 43 being connected to the hanging plate 41 through a buffer spring 44, a plurality of support springs 45 arranged on the outer side of the guide sleeve 42, and the end of the support spring 45 being connected to the inner wall of the vibration member installation site 31.

[0095] The axial elastic connection between the guide sleeve 42 and the support net 3 is realized by arranging the hanging plate 41 on the support net 3 and arranging the support plate 43 outside the guide sleeve 42. The radial elastic connection between the guide sleeve 42 and the support net 3 is realized by connecting a plurality of support springs 45 between the outer wall of the guide sleeve 42 and the inner wall of the vibration part installation work site opening 31. Therefore, the guide sleeve 42 itself has the elastic resistance to vibration and the elastic resistance to swing. The vibration part installed in the guide sleeve 42 can swing at a certain angle in the vibration part installation work site opening 31. When the vibration part is used, each vibration part can vibrate a region in the model cavity 21 in all directions, thereby improving the uniformity of the concrete filling.

[0096] Preferably, referring to Figure 7 , the first cooling pipe quick connector 5 comprises a first threaded connector 51 installed on the support net 3 and a first plug-in part 52 connected with the first threaded connector 51, and one end of the cooling pipe 7 is plugged into the first plug-in part 52.

[0097] The second cooling pipe quick connector 6 comprises a second plug-in part 61 installed on the bottom of the base 1, and the other end of the cooling pipe 7 is plugged into the second plug-in part 61.

[0098] The water inlet pipe assembly 8 comprises a plurality of branch water inlet pipes 81 and a water inlet main pipe 82 in communication with the branch water inlet pipes 81. The end of the branch water inlet pipe 81 is screwed with the first threaded connector 51. The water inlet main pipe 82 is provided with a flow rate sensor 83 for monitoring the flow rate of water flow and an electromagnetic valve 84 for controlling the flow rate of water. The end of the water inlet main pipe 82 is connected with a water storage tank through a water inlet pump 85.

[0099] The water outlet pipe assembly 9 comprises a branch water outlet passage 91 arranged in the base 1 and in communication with the second plug-in part 61, a total water outlet passage 92 in communication with the branch water outlet passage 91, and a water outlet pipe 93 connected with the end of the total water outlet passage 92. The end of the water outlet pipe 93 is connected with the water storage tank through a water outlet pump 94.

[0100] In this embodiment, the cooling pipe 7 is installed in a plug-in manner, which is convenient to install. Moreover, the branch water inlet pipe 81 is screwed with the first threaded connector 51, and the branch water inlet pipe 81 is convenient to disassemble and assemble. During the process of cooling the concrete blank 100 by the cooling pipe 7, the cooling water in the water storage tank enters the water inlet main pipe 82 through the water inlet pump 85, and then is dispersed to each branch water inlet pipe 81. The cooling water in the branch water inlet pipe 81 penetrates the concrete blank 100 through each cooling pipe 7, and finally enters the total water outlet passage 92 from the branch water outlet passage 91 in the base 1, and then enters the water storage tank through the water outlet pipe 93. During the flow of the cooling water in the cooling pipe 7, a large amount of heat inside the concrete blank 100 can be taken away, so that the concrete blank 100 is prevented from expanding due to the excessive heat inside.

[0101] In addition, with reference to Figure 8 , Figure 9 , the model plate steel skeleton 2 is spliced by four first model plate steel skeleton units 22 and four second model plate steel skeleton units 23, and the adjacent first model plate steel skeleton units 22 and second model plate steel skeleton units 23 are connected through splicing fixing assemblies 24.

[0102] The first model plate steel skeleton unit 22 comprises a first inner side skeleton plate 221, a first middle skeleton plate 222 and a first outer side skeleton plate 223, and the first inner side skeleton plate 221, the first middle skeleton plate 222 and the first outer side skeleton plate 223 are connected with each other through first reinforcing ribs.

[0103] The second model plate steel skeleton unit 23 comprises a second inner side skeleton plate 231, a second middle skeleton plate 232 and a second outer side skeleton plate 233, and the second inner side skeleton plate 231, the second middle skeleton plate 232 and the second outer side skeleton plate 233 are connected with each other through second reinforcing ribs.

[0104] The splicing fixing assembly 24 comprises a splicing main plate 240, inner side connecting plates 241, middle connecting plates 242 and outer side connecting plates 243 installed on both sides of the splicing main plate 240, the inner side connecting plates 241 on both sides of the splicing main plate 240 are connected with the first inner side skeleton plate 221 and the second inner side skeleton plate 231 through connecting pieces 25 respectively;

[0105] The middle connecting plates 242 on both sides of the splicing main plate 240 are connected with the first middle skeleton plate 222 and the second middle skeleton plate 232 through connecting pieces 25 respectively;

[0106] The outer side connecting plates 243 on both sides of the splicing main plate 240 are connected with the first outer side skeleton plate 223 and the second outer side skeleton plate 233 through connecting pieces 25 respectively;

[0107] In combination with Figure 8 and Figure 9 , the through holes on the inner side connecting plates 241, the first inner side skeleton plate 221 and the second inner side skeleton plate 231 for the connecting pieces 25 to pass through are waist-shaped holes, the through holes on the middle connecting plates 242, the first middle skeleton plate 222 and the second middle skeleton plate 232 for the connecting pieces 25 to pass through are waist-shaped holes, and the through holes on the outer side connecting plates 243, the first outer side skeleton plate 223 and the second outer side skeleton plate 233 for the connecting pieces 25 to pass through are waist-shaped holes, so that the assembled model plate steel skeleton 2 has a certain radial expansion deformation capacity. The connecting pieces 25 in the embodiment are bolts.

[0108] The first model plate steel framework unit 22, the second model plate steel framework unit 23 and the splicing fixing assembly 24 of the steel skeleton structure are all three-layer plate structures, and the strength of each is high. Since the number of the first model plate steel framework unit 22, the second model plate steel framework unit 23 and the splicing fixing assembly 24 is four, the splicing is completed to form the model plate steel framework 2 with an octagonal cross section. When the size of the model plate steel framework 2 is large, the model plate steel framework 2 is suitable for on-site assembly at the application site, and the operation is relatively convenient.

[0109] The structure of the model plate steel framework 2 is a detachable structure. Since the weight and volume of the model plate steel framework 2 are large, the model plate steel framework 2 is spliced by the first model plate steel framework unit 22 and the second model plate steel framework unit 23 to facilitate transportation and installation.

[0110] Another advantage of the detachable structure of the model plate steel framework 2 is that the model plate steel framework 2 has a certain radial expansion after splicing. The concrete blank 100 in the model cavity 21 will expand during the curing process. When the concrete blank 100 radially extrudes the model plate steel framework 2, the model plate steel framework 2 can adaptively expand radially, which also plays a role in preventing the concrete blank from bulging and deforming to a certain extent.

[0111] Further, referring to Figure 10 The base 1 includes a bottom plate 11, an inner support seat 12 connected to the bottom plate 11 and an outer support seat 13. The inner support seat 12 and the outer support seat 13 are provided with a clamping port 14. The first model plate steel framework unit 22, the second model plate steel framework unit 23 and the splicing fixing assembly 24 are inserted into the clamping port 14 away from the support net 3;

[0112] The inner wall of the outer support seat 13 is provided with a sealing support pad 15. The sealing support pad 15 is embedded and installed with a pressure sensor 16. The first inner side skeleton plate 221 of the first model plate steel framework unit 22 is in contact with the inner support seat 12. The second inner side skeleton plate 231 of the second model plate steel framework unit 23 is in contact with the inner support seat 12. The pressure sensor 16 can monitor the radial expansion pressure of the model plate steel framework 2 in real time.

[0113] The first outer side skeleton plate 223 of the first model plate steel framework unit 22 is in contact with the sealing support pad 15,

[0114] The second outer side skeleton plate 233 of the second model plate steel framework unit 23 is in contact with the sealing support pad 15.

[0115] After the bottom of the model plate steel skeleton 2 is inserted into the clamping interface 14, the firmness of the installation of the model plate steel skeleton 2 on the bottom plate 11 can be ensured, the inner side support seat 12 and the outer side support seat 13 play a sealing role on the contact position of the model plate steel skeleton 2 and the bottom plate 11, so as to ensure the bottom sealing performance of the model cavity 21, and in addition, after the model plate steel skeleton 2 is installed on the base 1, the support net 3 at the top of the model plate steel skeleton 2 can be fixed on the top by bolts, so as to ensure the firmness and strength of the model plate steel skeleton 2 after the whole installation.

[0116] Since the model plate steel skeleton 2 itself has a detachable structure, the assembled model plate steel skeleton 2 itself has a certain radial expansion performance, and the concrete blank 100 in the model cavity 21 will expand during the curing process, and when the concrete blank 100 radially extrudes the model plate steel skeleton 2, the model plate steel skeleton 2 can be adaptively expanded in the radial direction, and the outer wall of the expanded model plate steel skeleton 2 can extrude the sealing support pad 15, at this time, the pressure sensor 16 can sense the corresponding pressure signal.

[0117] Further, as Figure 11 In the embodiment, the flow rate sensor 83, the electromagnetic valve 84 and the pressure sensor 16 are connected to the control system 10, and the control system 10 comprises:

[0118] A first signal receiving module 101 is configured to receive the liquid flow rate signal of the flow rate sensor 83.

[0119] A second signal receiving module 102 is configured to receive the pressure signal of the pressure sensor 16.

[0120] A pressure signal variable feedback module 103 is connected to the second signal receiving module 102, and the pressure signal variable feedback module 103 is configured to monitor the rate of change of the pressure signal value of the pressure sensor 16 in a time period.

[0121] A logic processing unit 104 is connected to the first signal receiving module 101, the second signal receiving module 102 and the pressure signal variable feedback module 103.

[0122] An execution module 105 is connected to the logic processing unit 104 and is configured to control the opening amount of the electromagnetic valve 84.

[0123] When the rate of change of the pressure signal value of the pressure sensor 16 in a time period increases, the logic processing unit 104 controls the opening amount of the electromagnetic valve 84 to increase through the execution module 105.

[0124] After the concrete blank 100 is poured, the formula of the change of the internal temperature of the concrete blank 100 with time can be represented by the following formula:

[0125] T(t) = T0 + (T1 - T0)(1 - e^(-kt))

[0126] where T(t) represents the temperature inside the concrete at time t, T0 represents the initial temperature of the concrete, T1 represents the final temperature of the concrete, and k represents the temperature rise rate constant of the concrete. This formula can be used to calculate the temperature change of the concrete at any time after pouring.

[0127] The principle of the internal temperature change of the concrete blank 100 after pouring is that the concrete releases a large amount of heat during the hardening process, which is called the cement hydration reaction. The cement hydration reaction is an exothermic reaction that releases a large amount of heat energy, causing the temperature of the concrete to rise. At the same time, the temperature of the concrete is also affected by external environmental factors such as air temperature and wind speed. Therefore, the temperature change of the concrete after pouring is a complex process that needs to consider the influence of multiple factors. In actual engineering, the temperature change of the concrete has an important influence on the performance and service life of the concrete. High temperature can cause shrinkage, cracking and other diseases of the concrete, reducing the strength and durability of the concrete; low temperature can affect the early strength development and stability of the late strength of the concrete. Therefore, after the concrete blank 100 is poured, the temperature of the concrete blank 100 needs to be monitored and controlled to ensure the performance and service life of the concrete.

[0128] In addition, the relationship between the temperature of the concrete blank 100 after pouring and the thickness of the concrete blank 100 can be represented by the following formula:

[0129] ΔT = (T1 - T2)*exp(-α*r / λ)

[0130] where ΔT represents the temperature difference inside the concrete, T1 represents the temperature of the concrete surface, T2 represents the temperature inside the concrete, α represents the thermal conductivity of the concrete, r represents the radius of the poured body, and λ represents the thermal diffusivity of the concrete.

[0131] The thermal conductivity α and the thermal diffusivity λ in the above formula are physical parameters of the concrete, which reflect the thermal conductivity and thermal diffusion characteristics of the concrete. The larger the thermal conductivity α, the stronger the thermal conductivity of the concrete, and the faster the temperature change; the larger the thermal diffusivity λ, the stronger the thermal diffusion ability of the concrete, and the more uniform the temperature change. The above formula can be used to calculate the distribution of the temperature inside the concrete, thereby monitoring and controlling the temperature of the concrete. In actual engineering, the temperature change of the concrete has an important influence on the performance and service life of the concrete. Therefore, after the concrete is poured, the temperature of the concrete needs to be monitored and controlled to ensure the performance and service life of the concrete.

[0132] Therefore, the application adopts the control system 10 to monitor the expansion of the concrete blank 100, and the actual expansion of the concrete blank 100 can directly feedback the temperature change in the concrete blank 100, so that the heat conduction and cooling can be accurately guided according to the temperature change.

[0133] According to the steel framework structure for power component casting of power distribution provided by the embodiment of the application, the application further provides a method for power component casting of power distribution, comprising the following steps:

[0134] S1, assembling the steel framework structure for power component casting of power distribution;

[0135] S2, filling the concrete into the model cavity 21;

[0136] S3, installing a vibrating element on each vibrating element guiding and supporting assembly 4, each vibrating element is inserted into the vibrating element guiding and supporting assembly 4 and extends into the model cavity 21, and the vibrating element performs circumferential swing vibration and axial movement vibration to uniformly mix the concrete;

[0137] S4, the water inlet pipe assembly 8 provides cooling water to each cooling pipe 7, the cooling water is finally guided out from the water outlet pipe assembly 9 after passing through the concrete blank 100, and the cooling water flowing in the cooling pipe 7 takes away the heat in the concrete blank 100;

[0138] S5, disassembling the steel framework structure for power component casting of power distribution to obtain the required power component.

[0139] In the step S4, the step S4 specifically comprises:

[0140] The flow rate sensor (83) and the electromagnetic valve (84) are arranged on the water inlet main pipe (82), the pressure sensor (16) is arranged on the base (1), the control system (10) collects the pressure signal of the pressure sensor (16) and the flow rate signal of the flow rate sensor (83); when the change rate of the pressure signal in a period is greater than a set value, the control system (10) controls the electromagnetic valve (84) to increase the opening amount, the flow rate of the cooling water is increased; and / or the temperature of the cooling water is reduced until the change rate of the pressure signal is zero.

[0141] In the above method, the control system 10 is mainly used for automatic control of the flow of cooling water in the cooling pipe 7. In actual operation, when the concrete blank 100 in the mold cavity 21 is formed and cured, the water inlet pump 85, the electromagnetic valve 84 on the water inlet main pipe 82 and the water outlet pump 94 on the water outlet pipe 93 are opened. At this time, the cooling pipe 7 is in a water circulation state with the water storage tank, and the cooling water in the cooling pipe 7 can take away the heat inside the concrete blank 100. During the curing process of the concrete blank 100, there will be a period of time in a serious heating state. It is difficult to grasp the time node of this serious heating state, which is mainly related to the thickness of the concrete blank 100 and the external environment temperature. Therefore, the pressure sensor 16 installed on the sealing support pad 15 is used to monitor the time node of the serious heating of the concrete blank 100 in real time. In the specific monitoring process, since the concrete blank 100 expands most when it is in a serious heating state, the concrete blank 100 is in a rapid expansion state at this time. Moreover, the mold plate steel framework 2 of the present application is a structure that can deform in a small range in the radial direction. When the concrete blank 100 radially extrudes the mold plate steel framework 2, the mold plate steel framework 2 can expand in the radial direction. At this time, the outer wall of the mold plate steel framework 2 extrudes the pressure sensor 16 installed on the sealing support pad 15. The pressure sensor 16 can transmit the sensed pressure signal to the control system 10. Since the cooling pipe 7 is continuously conducting heat to the inside of the concrete blank 100 at this time, the pressure signal sensed by the pressure sensor 16 is generally in a relatively stable state under normal circumstances. If the concrete blank 100 reaches the time node of serious heating, the pressure signal sensed by the pressure sensor 16 at this time will be in a state of continuous rise in a very short time. At this time, the pressure signal variable feedback module 103 can capture this signal. The pressure signal variable feedback module 103 feeds back the situation that the pressure signal value change rate of the pressure sensor 16 increases in a time period to the logic processing unit 104. The logic processing unit 104 controls the opening of the electromagnetic valve 84 to be larger through the execution module 105, so that the flow of cooling water in the cooling pipe 7 is rapidly increased, thereby increasing the intensity of heat conduction to the inside of the concrete blank 100, until the pressure signal sensed by the pressure sensor 16 tends to be stable.

[0142] After the flow of water in the cooling pipe 7 is increased for a period of time, if the pressure signal sensed by the pressure sensor 16 is still in a state of continuous rise, it means that the effect of heat conduction of the cooling water to the inside of the concrete blank 100 is not very significant. At this time, manual cooling is needed. The main operation method is to add new cooling water to the water storage tank to cool the circulating water as a whole. At the same time, water can also be sprayed on the surface of the concrete blank 100 by manual operation to cool the outside of the concrete blank 100, until the pressure signal sensed by the pressure sensor 16 tends to be stable.

[0143] The steel framework structure for power component casting for power distribution provided by the embodiment of the present application is characterized in that a plurality of vibration piece installation work site openings 31 are arranged on the support net 3, and an elastic vibration piece guide support assembly 4 is arranged at the vibration piece installation work site opening 31; after the model cavity 21 of the steel framework structure is filled with the concrete raw material, the support net 3 on the top of the model plate steel framework 2 can provide a construction platform for the constructor; when the constructor uses the vibration piece, the vibration piece is inserted into the guide sleeve 42 and extends into the model cavity 21; since the number of the vibration piece installation work site openings 31 on the support net 3 is multiple, a plurality of vibration pieces can be simultaneously installed on the support net 3; when the plurality of vibration pieces vibrate the concrete in the model cavity 21, the uniformity of the concrete filled in the model cavity 21 can be ensured; since the outer side of the guide sleeve 42 of the vibration piece guide support assembly 4 is provided with a support plate 43, the support plate 43 is connected with the hanging plate 41 through the buffer spring 44, the outer side of the guide sleeve 42 is provided with a plurality of support springs 45, and the end of the support spring 45 is connected with the inner wall of the vibration piece installation work site opening 31, therefore, the guide sleeve 42 itself has the elastic resistance to the vibration and the elastic swing, and therefore, the vibration piece installed in the guide sleeve 42 can swing at a certain angle in the vibration piece installation work site opening 31; when the constructor uses the vibration piece, each vibration piece can vibrate a region in the model cavity 21 in all directions, and the uniformity of the concrete filling is improved.
