Description

Technical Field

[0001] The present invention relates to the technical field of box-type substations, and in particular to a modular and rapidly assembled box-type substation. Background Art

[0002] With the acceleration of urbanization and the continuous growth of electricity demand, traditional brick-concrete structure substations have been unable to meet the modern power system's demand for efficient, flexible and safe power supply due to their shortcomings such as long construction period, large footprint and complex construction. Therefore, box-type substations have emerged as a new type of power supply and distribution equipment and are widely used in urban distribution networks, industrial parks, temporary construction sites, new energy power generation and other fields.

[0003] Box-type substations usually integrate high-voltage switchgear, transformers, low-voltage distribution devices, automatic control systems and auxiliary facilities (such as lighting, ventilation, fire protection, etc.) in one or more metal boxes to form a fully functional and compact standardized power supply and distribution unit. However, although the existing box-type substations are relatively mature in structure and function, there are still some technical problems that need to be solved in actual application, especially in terms of module installation and safety protection: First, the electrical equipment modules inside the box-type substation are usually fixed to the bracket or base in the box by bolt connection. This installation method is not suitable for the following applications: The installation method requires tightening the bolts one by one, which is cumbersome and time-consuming, affecting the progress of on-site construction. Moreover, when disassembling the equipment, the bolts need to be removed one by one, which is inconvenient to operate and easily causes damage to parts. Secondly, the internal space of the box-type substation is limited, and various high and low voltage equipment are densely arranged. Once an electrical fault occurs in a module (such as short circuit, overload, insulation breakdown, etc.), it may cause local overheating or even fire. Due to the lack of effective fire isolation measures between modules in the existing box-type substation, the fire risk is highly contagious, which may affect adjacent modules, expand the scope of the accident, and bring greater economic losses and safety hazards. Summary of the Invention

[0004] In view of this, the present invention provides a modular and quickly assembled box-type substation, which can solve the shortcomings of the existing box-type substation in which the installation and disassembly process of the electrical equipment modules is cumbersome, time-consuming, inconvenient to operate, and lacks effective fire isolation measures between modules.

[0008] Further explanation: the blocking mechanism includes a connecting frame, an electric roller, a fireproof cloth and a baffle. The connecting frame is installed at intervals on the box body, and the electric roller is also rotatably arranged at intervals on the box body. The electric roller is located on the inner side of the connecting frame. The fireproof cloth is wrapped around the electric roller. One end of the fireproof cloth is connected to the electric roller. A baffle is provided on the revolving door, and the baffle is used to prevent the fireproof cloth from falling and unfolding.

[0009] Further explanation: the locking mechanism includes an electric push rod and a locking block. The electric push rod is installed on the movable platform. The locking block is connected to the telescopic rod of the electric push rod. The locking block is inserted into the bottom of the box to lock the movable platform.

[0010] Further description, it also includes a counterweight strip, the other end of the fireproof cloth is connected to the counterweight strip, and the counterweight strip is used to balance the other end of the fireproof cloth.

[0011] Further explanation, it also includes a locking mechanism, which includes a locking block and a fourth spring. Locking blocks are slidingly arranged at intervals at the bottom of the box body. The locking blocks are used to lock the revolving door. The fourth spring is connected between the locking block and the bottom of the box body.

[0012] Further explanation: it also includes a fire extinguishing mechanism, which includes a storage frame, a discharge frame, a connecting pipe and an electric control valve. The storage frame is installed on the top of the box body, the discharge frame is connected to the revolving door, and a connecting pipe is connected between the storage frame and the discharge frame, and an electric control valve is provided on the connecting pipe.

[0013] The beneficial effects of the present invention are as follows: 1.

[0033] See Figure 5 and Figure 6 As shown, the release mechanism includes a pressure block 1001 and a third spring 1002; a pressure block 1001 is slidably provided on the upper outer side of the base 9, and the pressure block 1001 is used to squeeze the limit block 7; four third springs 1002 are provided between the bottom of the pressure block 1001 and the base 9.

[0034] See Figure 7 As shown, the detection mechanism includes a flame detection sensor 1101 and a controller 1102; three flame detection sensors 1101 are arranged at intervals on the top of the box 1, and the three flame detection sensors 1101 are used to monitor three electrical devices 3 respectively; a controller 1102 is arranged on the rear side of the top of the box 1, and the flame detection sensor 1101 is electrically connected to the controller 1102.

[0035] See Figures 8-10As shown, the blocking mechanism includes a connecting frame 1401, an electric roller 1402, a fireproof cloth 1403 and a baffle 1404; three connecting frames 1401 are installed at intervals on the upper rear side of the box body 1; three electric rollers 1402 are rotatably arranged at intervals on the upper rear side of the box body 1, and the three electric rollers 1402 are respectively located on the inner sides of the three connecting frames 1401, and the electric rollers 1402 are electrically connected to the controller 1102; a fireproof cloth 1403 is wound around the electric roller 1402, and one end of the fireproof cloth 1403 is connected to the electric roller 1402; a baffle 1404 is provided on the upper front side of the revolving door 12, and the baffle 1404 is used to prevent the fireproof cloth 1403 from falling and unfolding.

[0036] See Figure 11 and Figure 12 As shown, the locking mechanism includes an electric push rod 1501 and a locking block 1502; the electric push rod 1501 is installed in the middle of the rear side of the movable platform 4, and the electric push rod 1501 is electrically connected to the controller 1102; the locking block 1502 is connected to the telescopic rod of the electric push rod 1501, and the locking block 1502 is locked into the bottom of the box body 1 to lock the movable platform 4.

[0037] In the initial state, the block 1502 is locked into the bottom of the box 1 to lock the movable platform 4, so that the first spring 5 is in a compressed state;

[0038] When in use, install the box body 1 in the designated position, then pull the box door 2 to rotate and open it, and then carry out the installation operation of the electrical device 3: first move the electrical device 3 into the box body 1, then place the electrical device 3 on the top of the movable platform 4, and make the electrical device 3 between the positioning blocks 6. During this period, when the base 9 on the electrical device 3 contacts the inclined surface of the top of the limit block 7, the base 9 on the electrical device 3 will squeeze the limit block 7 to move to the side close to the inside of the positioning block 6, and the second spring 8 is compressed. When the base 9 on the electrical device 3 is separated from the limit block 7, the second spring 8 returns to its original state, and the second spring 8 drives the limit block 7 to move to the side away from the inside of the positioning block 6 and reset, so that the positioning block 6 limits the base 9 on the electrical device 3 (such as Figure 6 As shown), the electrical equipment 3 is limited, thereby completing the installation of the new electrical equipment 3;

[0039] Then pull the box door 2 to reverse and close it, and the box-type substation can be used. Later, when the electrical equipment 3 needs to be disassembled, pull the box door 2 again to rotate it open, and then perform the disassembly operation of the electrical equipment 3: first press the pressure block 1001 to move downward, and the third spring 1002 is compressed. When the pressure block 1001 contacts the inclined surface at the top of the limit block 7, the pressure block 1001 will squeeze the limit block 7 to move to the side close to the inside of the positioning block 6, and the second spring 8 is compressed to release the limit block 7 from the limit on the base 9. Then move the electrical equipment 3 upward, so that the electrical equipment 3 drives the base 9 and the pressure block 1001 to move upward, thereby making the base 9 move from the movable level. The second spring 8 returns to its original shape, and the second spring 8 drives the limit block 7 to move to the side away from the inside of the positioning block 6 and reset. Then, the pressure block 1001 is released, and the third spring 1002 returns to its original shape, and the third spring 1002 drives the pressure block 1001 to move upward and reset. Then, the electrical equipment 3 is moved out of the box body 1. In this way, the disassembly of the electrical equipment 3 can be completed. Then, the box door 2 can be pulled back to close.

[0040] During the use of the box-type substation, the fire situation of the electrical equipment 3 is monitored by the flame detection sensor 1101. When the flame detection sensor 1101 monitors that the corresponding electrical equipment 3 is on fire, the corresponding flame detection sensor 1101 will send a signal. After receiving the signal, the controller 1102 will control the corresponding electric push rod 1501 to drive the card block 1502 to move upward, so that the card block 1502 is no longer stuck in the bottom of the box body 1, thereby releasing the limit of the corresponding movable platform 4. At this time, the corresponding first spring 5 returns to its original state, and the first spring 5 drives the corresponding movable platform 4 and the electrical equipment 3 on fire to move backward. When the electrical equipment 3 on fire is in contact with the ventilation frame 13 When in contact, the burning electrical equipment 3 will be squeezed by the ventilation frame 13 to rotate and open the revolving door 12, so that the burning electrical equipment 3 can be transported out of the box body 1 by the corresponding movable platform 4. When the revolving door 12 rotates and opens, the revolving door 12 will drive the baffle 1404 to rotate and open, so that the baffle 1404 no longer blocks the fireproof cloth 1403 on the electric roller 1402, so that the fireproof cloth 1403 naturally falls down and unfolds under the influence of gravity, and then the fireproof cloth 1403 isolates the burning electrical equipment 3 from the inside of the box body 1 to prevent the fire from affecting the other electrical equipment 3 inside the box body 1, and by removing the burning electrical equipment 3 from the box body 1 The fireproof cloth 1403 is moved outwards, which makes it convenient for firefighters to extinguish the electrical equipment 3 that has caught fire. After that, when the electrical equipment 3 that has caught fire is extinguished, the damaged electrical equipment 3 is removed from the movable platform 4 by disassembling the electrical equipment 3, and then the electrical equipment 3 is installed to reinstall the normal electrical equipment 3 on the movable platform 4. Then the electric roller 1402 is controlled to start, so that the electric roller 1402 rewinds the fireproof cloth 1403, so that the fireproof cloth 1403 is retracted, and then the box door 2 is pulled to rotate and open, and then the corresponding movable platform 4 is pulled forward, and the first spring 5 is compressed, so that the movable platform 4 drives the electrical equipment 3 thereon to move forward. Move it back into the box 1. When the electrical equipment 3 is separated from the ventilation frame 13, the revolving door 12 will naturally reverse and close under the action of gravity, so that the revolving door 12 drives the baffle 1404 to reverse and reset, so that the baffle 1404 blocks the fireproof cloth 1403 on the electric roller 1402 again. After that, when the movable platform 4 moves forward and resets, the controller 1102 controls the corresponding electric push rod 1501 to drive the card block 1502 to move downward and reset, so that the card block 1502 is re-engaged in the bottom of the box 1, thereby limiting the corresponding movable platform 4, and then controls the electric roller 1402 to close through the controller 1102, and then pushes the box door 2 to reverse and close.

[0041] See Figure 10 As shown, a counterweight strip 16 is also included; the other end of the fireproof cloth 1403 is connected to the counterweight strip 16, and the counterweight strip 16 is used to counterweight the other end of the fireproof cloth 1403.

[0042] By setting up the counterweight bar 16, the counterweight bar 16 can be used to increase the weight of the other end of the fireproof cloth 1403, so that the other end of the fireproof cloth 1403 has enough weight to fall, so that the fireproof cloth 1403 can be fully unfolded to ensure that the fireproof cloth 1403 can completely block the burning electrical equipment 3 from the inside of the box 1.

[0043] See Figure 11-13 As shown, it also includes a locking mechanism, which includes a locking block 17 and a fourth spring 18; three groups of locking blocks 17 are slidingly arranged at intervals on the rear side of the bottom of the box body 1, and the number of each group of locking blocks 17 is two. The two locking blocks 17 in one group are distributed left and right, and the locking blocks 17 are stuck in the bottom of the revolving door 12. The three groups of locking blocks 17 are used to lock the three revolving doors 12 respectively. The top and the upper rear side of the locking block 17 are set as inclined surfaces. When the movable platform 4 moves backward, it will contact the inclined surface of the top of the locking block 17; two fourth springs 18 are connected between the bottom of the locking block 17 and the bottom of the box body 1.

[0044] When the movable platform 4 moves backward to contact the inclined surface at the top of the locking block 17, the movable platform 4 will squeeze the locking block 17 to move downward, and the fourth spring 18 will be compressed, so that the locking block 17 will leave the bottom of the revolving door 12, thereby releasing the lock of the revolving door 12; when the movable platform 4 moves forward to separate from the inclined surface at the top of the locking block 17, the fourth spring 18 will return to its original state, and the fourth spring 18 will drive the locking block 17 to move upward and reset. Subsequently, when the revolving door 12 is reversed to contact the inclined surface on the rear upper side of the locking block 17, the revolving door 12 will squeeze the locking block 17 to move downward, and the fourth spring 18 will be compressed. When the revolving door 12 is reversed and reset, the fourth spring 18 will return to its original state, and the fourth spring 18 will drive the locking block 17 to move upward and reset, so that the locking block 17 is stuck in the bottom of the revolving door 12, thereby utilizing the locking block 17 to lock the revolving door 12, thereby preventing the revolving door 12 from being opened at will.

[0045] See Figure 14 and Figure 15 As shown, a fire extinguishing mechanism is also included, which includes a storage frame 19, a discharge frame 20, a connecting pipe 21 and an electric control valve 22; the storage frame 19 is installed on the top of the box body 1; the discharge frame 20 is connected to the upper front side of the revolving door 12; a connecting pipe 21 is connected between the storage frame 19 and the discharge frame 20; and an electric control valve 22 is provided on the connecting pipe 21.

[0046] By setting up a fire extinguishing mechanism, the dry powder fire extinguishing agent can be pressurized and injected into the storage frame 19 during use. When the revolving door 12 rotates, the revolving door 12 will drive the discharging frame 20 to rotate, so that the discharging frame 20 is above the electrical equipment 3 on fire. Then, the controller 1102 is used to control the corresponding electrically controlled valve 22 to open, so that the dry powder fire extinguishing agent in the storage frame 19 can enter the discharging frame 20 through the corresponding connecting pipe 21, so that the corresponding discharging frame 20 sprays the dry powder fire extinguishing agent toward the electrical equipment 3 on fire, thereby extinguishing the fire of the electrical equipment 3 on fire; after that, when the fire of the electrical equipment 3 is extinguished, the corresponding electrically controlled valve 22 can be controlled to close by the controller 1102. Then, when the revolving door 12 reverses and resets, the revolving door 12 will drive the discharging frame 20 to reverse and reset.
