Description

Technical Field

[0001] The present invention relates to the technical field of power cabinets, and specifically provides a buried outdoor safety power cabinet. Background Art

[0002] A buried outdoor safety power cabinet is a power equipment cabinet specifically designed for outdoor environments and partially or fully buried underground. The following aspects will be described from the aspects of structure, function, application scenarios, etc. Cabinet material: It is usually made of high-strength and corrosion-resistant materials, such as stainless steel, fiberglass, etc. These materials can effectively resist the erosion of harsh outdoor environments, including rain, sand, chemicals, etc., ensuring the service life and safety of the cabinet. Embedding method: There are two common forms, namely, the overall buried type and the semi-buried type. The overall buried type is to completely bury the entire power cabinet underground, and only maintenance openings and ventilation openings are set on the ground; the semi-buried type is to bury a part of the power cabinet underground and the other part is exposed above the ground. The exposed part usually has a protective door and an operation panel, etc.

[0003] The patent with the publication number CN111479422B discloses a buried outdoor safety power cabinet, including an upper shell, a wire-releasing shell, a cabinet body, a winding shaft, a PLC controller, a driver, a rubber composite plate and a pressure sensor. The wire-releasing shell is bolted below the upper shell, and a chute is opened inside the upper shell. An activity plate is arranged inside the upper shell. A winding shaft is arranged inside the lower shell. Guide wheels are arranged on the left and right sides inside the chute and inside the lower shell. The end of the steel cable passes through the wire-releasing shell and is connected to the activity plate. A pressure sensor is arranged inside the rubber composite plate. This buried outdoor safety power cabinet is provided with an activity plate and a winding shaft. During use, the winding shaft drives the steel cable to move, so that the winding shaft stretches the activity plate, so that the activity plate can move up and down, so that the cabinet body above the activity plate can be jacked out, avoiding the cabinet body from being exposed to the air and the outside for a long time.

[0004] During the use of the above device, it is difficult to quickly dissipate heat from the power distribution cabinet. Electrical components in the power distribution cabinet generate heat during operation. If the heat cannot be dissipated in time and the temperature continues to rise, it will accelerate the aging of the insulating material of the components. Therefore, a buried outdoor safety power cabinet is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a buried outdoor safety power cabinet in view of the deficiencies in the above-mentioned prior art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: an embedded outdoor safety power cabinet, including a chassis, wherein a heat dissipation device is provided on the inner wall of the chassis, a fire prevention device is provided on the inner wall of the chassis, and a settlement prevention device is provided on the outer wall of the chassis; the heat dissipation device includes a condensation box, a pipeline, a heat conduction plate, a support plate I, a motor, a reciprocating lead screw, a concave frame, a hinged plate I, a cross plate, and an L-shaped plate I. The condensation box is fixedly installed on the inner wall of the chassis, the pipeline is fixedly communicated with the top of the condensation box, the heat conduction plate is fixedly installed on the inner wall of the chassis. By using a refrigerant to absorb the heat absorbed by the heat conduction plate, rapid heat dissipation of the chassis is achieved, protecting electrical equipment. When the electrical equipment in the power distribution cabinet operates, it generates heat. If the heat cannot be dissipated in time, the temperature of the equipment will rise. In a long-term high-temperature environment, the insulation performance of the electrical equipment will decline, accelerating equipment aging, shortening the service life of the equipment, and even possibly causing equipment failure or damage. By using a refrigerant for heat dissipation, the temperature inside the power distribution cabinet can be effectively controlled, protecting the electrical equipment and ensuring its stable and reliable operation. The support plate I is fixedly connected to the inner wall of the chassis, the motor is fixedly connected to the right side of the support plate I, the reciprocating lead screw is fixedly connected to the output end of the motor, the concave frame is fixedly connected to the inner wall of the chassis, the hinged plate I is hinged to the inner wall of the concave frame through a torsion spring, the cross plate is movably connected to the circumferential surface of the reciprocating lead screw, the L-shaped plate I is fixedly connected to the outer wall of the cross plate, the circumferential surface of the pipeline is fixedly communicated with the inner wall of the heat conduction plate, the circumferential surface of the reciprocating lead screw is rotatably connected to the inner wall of the chassis, and the bottom of the cross plate is slidably connected to the inner wall of the chassis. By driving the hinged plate I to move through the movement of the L-shaped plate I, the flow state of the heat exchange channel or the heat exchange medium can be changed, etc., enabling the hot air inside the power distribution cabinet to exchange heat with the outside cold air or cooling medium more fully and quickly, accelerating heat dissipation, and improving the overall heat exchange efficiency, thereby achieving rapid cooling and ensuring that the temperature inside the power distribution cabinet is always within a reasonable range.

[0007] Preferably, the fire prevention device includes a first fixing plate, a second hinged plate, a second fixing plate, a hinged rod, a track, a fire bucket, a sprinkler head, an L-shaped second plate, an upward moving plate, and a baffle. The first fixing plate is fixedly connected to the top of the L-shaped first plate. The second hinged plate is hinged to the inner wall of the first fixing plate. The circumferential surface of the hinged rod is hinged to the inner wall of the second hinged plate. The second fixing plate is fixedly connected to the hinged rod. The track is fixedly connected to the inner wall of the chassis. The fire bucket is fixedly connected to the inner wall of the chassis through a bearing plate. The L-shaped second plate is slidably connected to the inner wall of the track. The sprinkler head is fixedly connected to the top of the L-shaped second plate. The rotating function of the sprinkler head also starts to play a role. The sprinkler head adopts a rotatable design. Through the built-in rotating motor gear transmission device, according to the position information of the fire source, it can achieve multi-angle rotation. In this way, when the sprinkler head moves upward close to the fire source, it can adjust the spraying angle by rotation to achieve precise fire extinguishing of the fire source. The fire extinguishing material in the fire bucket is transported to the sprinkler head through a pipeline and is sprayed out at the best angle and strength after the sprinkler head is accurately positioned, effectively extinguishing the fire. The upward moving plate is fixedly connected to the top of the L-shaped second plate. The baffle is fixedly connected to the top of the upward moving plate. The right side of the baffle contacts the inner wall of the chassis. The right side of the second fixing plate is fixedly connected to the left side of the L-shaped second plate. The right side of the second fixing plate is slidably connected to the left side of the track. The baffle contacts the track, effectively extinguishing the fire and minimizing the damage caused by the fire to the power distribution cabinet. The baffle blocks the ventilation opening to prevent air from entering the power distribution cabinet to assist combustion. To prevent air from entering the power distribution cabinet to assist combustion, when a fire hazard signal is detected, the baffle is pushed to quickly move to the position of the ventilation opening. The size of the baffle is precisely matched with the ventilation opening and can tightly block the ventilation opening, effectively cutting off the channel for external air to enter the power distribution cabinet, thereby reducing the oxygen content in the fire area and inhibiting the further spread of the fire, minimizing the damage caused by the fire to the power distribution cabinet.

[0008] Preferably, the anti-settlement device includes an N-shaped plate, rollers, a rotating rod, a cross fan, and a filter box. The N-shaped plate is fixedly connected to the top of the baffle. The filter box is fixedly connected to the inner wall of the chassis. The rotating rod is rotatably connected to the inner wall of the filter box. The cross fan is fixedly connected to the circumferential surface of the rotating rod, so that the cross fan stirs the desiccant in the filter box to maintain a dry environment. The main function of the desiccant is to absorb moisture in the air and reduce the humidity of the surrounding environment. In many scenarios that require moisture-proofing, such as buried outdoor power cabinets, through the stirring of the cross fan, the desiccant can be more fully in contact with the air, absorb moisture more efficiently, keep the space dry, and prevent items from being damaged, deteriorated or mildewed due to moisture. The rollers are fixedly connected to the front of the rotating rod. The anti-settlement device further includes a horizontal plate, a concave plate, a clamping plate, and a second support plate. The horizontal plate is fixedly connected to the right side of the baffle. The concave plate is installed on the outer wall of the chassis. The clamping plate is fixedly connected to the rear of the chassis. The second support plate is fixedly connected to the bottom of the concave plate. The right side of the N-shaped plate is in contact with the inner wall of the chassis. The outer wall of the horizontal plate is slidably connected to the inner wall of the chassis. By the support of the second support plate, the settlement of the power distribution cabinet is prevented. The power distribution cabinet itself contains various electrical components, circuits, etc. and is heavy. The second support plate can disperse the overall weight of the power distribution cabinet over a larger area and transfer it to the ground or the foundation structure. Through this dispersion effect, the pressure borne per unit area is reduced, and the possibility of ground subsidence or foundation structure damage caused by excessive local pressure is reduced, thus effectively preventing uneven settlement of the power distribution cabinet.

[0009] The present invention adopts the above technical solutions and can bring the following beneficial effects: 1. For the buried outdoor safety power cabinet, through the mutual cooperation among the condensation box, the pipeline, the heat conduction plate, the first support plate, the motor, the reciprocating lead screw, the concave frame, the first hinged plate, the cross plate, and the first L-shaped plate, the heat absorbed by the heat conduction plate is absorbed by the coolant to achieve rapid heat dissipation of the chassis and protect the electrical equipment. The electrical equipment in the power distribution cabinet generates heat during operation. If the heat cannot be dissipated in time, the temperature of the equipment will rise. In a long-term high-temperature environment, the insulation performance of the electrical equipment will decline, accelerating equipment aging, shortening the service life of the equipment, and even possibly causing equipment failure or damage. Through heat dissipation by the coolant, the temperature inside the power distribution cabinet can be effectively controlled, protecting the electrical equipment and ensuring its stable and reliable operation. By moving the first L-shaped plate to drive the first hinged plate to stir, the flow state of the heat exchange channel or the heat exchange medium can be changed, etc., so that the hot air inside the power distribution cabinet can exchange heat more fully and quickly with the outside cold air or the cooling medium, accelerating heat dissipation and improving the overall heat exchange efficiency, thereby achieving rapid cooling and ensuring that the temperature inside the power distribution cabinet is always within a reasonable range.

[0010] 2. The embedded outdoor safety power cabinet, through the cooperation of fixing plate 1, hinged plate 2, fixing plate 2, hinged rod, track, fire bucket, sprinkler, L-shaped plate 2, upward moving plate, and baffle, the rotating function of the sprinkler also starts to play a role. The sprinkler adopts a rotatable design. Through the built-in rotating motor gear transmission device, according to the position information of the fire source, it can achieve multi-angle rotation. In this way, when the sprinkler moves upward close to the fire source, it can adjust the spraying angle by rotation to achieve precise fire extinguishing of the fire source. The fire extinguishing material in the fire bucket is transported to the sprinkler through a pipeline. After the sprinkler is accurately positioned, it sprays out at the best angle and force to effectively extinguish the fire, minimizing the damage caused by the fire to the power cabinet to the greatest extent. The baffle blocks the ventilation opening to prevent air from entering the power cabinet to assist combustion. To prevent air from entering the power cabinet to assist combustion, when a fire hazard signal is detected, the baffle is pushed to quickly move to the position of the ventilation opening. The size of the baffle precisely matches the ventilation opening and can tightly block the ventilation opening, effectively cutting off the passage of external air entering the power cabinet, thereby reducing the oxygen content in the fire area and inhibiting the further spread of the fire, minimizing the damage caused by the fire to the power cabinet to the greatest extent.

[0011] 3. The embedded outdoor safety power cabinet, through the cooperation of the N-shaped plate, roller, rotating rod, cross fan, filter box, horizontal plate, concave plate, clamping plate, and support plate 2, enables the cross fan to stir the desiccant in the filter box to maintain a dry environment. The main function of the desiccant is to absorb moisture in the air and reduce the humidity of the surrounding environment. In many scenarios that require moisture-proofing, such as an embedded outdoor power cabinet, through the stirring of the cross fan, the desiccant can be more fully in contact with the air and absorb moisture more efficiently, keeping the space dry and preventing items from being damaged, deteriorated, or moldy due to moisture. The support plate 2 prevents the power cabinet from settling. The power cabinet itself contains various electrical components, circuits, etc., and has a large weight. The support plate 2 can disperse the overall weight of the power cabinet over a larger area and transfer it to the ground or the foundation structure. Through this dispersion effect, the pressure borne per unit area is reduced, and the possibility of ground subsidence or foundation structure damage caused by excessive local pressure is decreased, effectively preventing uneven settlement of the power cabinet.

By driving the hinge plate one 208 to swing through the movement of the L-shaped plate one 210, the heat exchange channel or the flow state of the heat exchange medium can be changed, etc., so that the hot air in the power distribution cabinet can exchange heat with the outside cold air or cooling medium more fully and quickly, accelerating the heat dissipation and improving the overall heat exchange efficiency, thereby realizing rapid cooling and ensuring that the temperature in the power distribution cabinet is always within a reasonable range.

[0016] The fire prevention device 3 includes a first fixed plate 301, a second hinged plate 302, a second fixed plate 303, a hinged rod 304, a track 305, a fire bucket 306, a nozzle 307, a second L-shaped plate 308, an upward moving plate 309, and a baffle 310. The first fixed plate 301 is fixedly connected to the top of the first L-shaped plate 210. The second hinged plate 302 is hinged to the inner wall of the first fixed plate 301. The circumferential surface of the hinged rod 304 is hinged to the inner wall of the second hinged plate 302. The second fixed plate 303 is fixedly connected to the hinged rod 304. The track 305 is fixedly connected to the inner wall of the chassis 1. The fire bucket 306 is fixedly connected to the inner wall of the chassis 1 through a bearing plate. The second L-shaped plate 308 is slidably connected to the inner wall of the track 305. The nozzle 307 is fixedly connected to the top of the second L-shaped plate 308. By driving the first fixed plate 301 to move through the first L-shaped plate 210, the movement of the first fixed plate 301 drives the second hinged plate 302 to move, the movement of the second hinged plate 302 drives the second fixed plate 303 to move, the movement of the second fixed plate 303 drives the second L-shaped plate 308 to move, and the movement of the second L-shaped plate 308 drives the nozzle 307 to move. The up and down movement of the nozzle 307 causes the nozzle 307 to move upward. The nozzle 307 is set to be rotatable, so that the nozzle 307 can achieve precise fire extinguishing. When the fire prevention device 3 detects a fire hazard in the power distribution cabinet, the second L-shaped plate 308 starts to operate, and the upward moving plate 309 moves upward along the track 305. Since the nozzle 307 is installed on the second L-shaped plate 308, the nozzle 307 moves upward accordingly. At the same time, the rotation function of the nozzle 307 also starts to play a role. The nozzle 307 adopts a rotatable design. Through the built-in rotary motor 205 gear transmission device, according to the position information of the fire source, it can achieve multi-angle rotation. In this way, when the nozzle 307 moves upward close to the fire source, it can adjust the spraying angle by rotation to achieve precise fire extinguishing of the fire source. The upward moving plate 309 is fixedly connected to the top of the second L-shaped plate 308. The baffle 310 is fixedly connected to the top of the upward moving plate 309. The right side of the baffle 310 is in contact with the inner wall of the chassis 1. The right side of the second fixed plate 303 is fixedly connected to the left side of the second L-shaped plate 308. The right side of the second fixed plate 303 is slidably connected to the left side of the track 305. The baffle 310 is in contact with the track 305. By driving the first fixed plate 301 to move through the first L-shaped plate 210, the movement of the first fixed plate 301 drives the second hinged plate 302 to move, the movement of the second hinged plate 302 drives the second fixed plate 303 to move, the movement of the second fixed plate 303 drives the second L-shaped plate 308 to move, and the movement of the second L-shaped plate 308 drives the nozzle 307 to move. The up and down movement of the nozzle 307 causes the nozzle 307 to move upward. The nozzle 307 is set to be rotatable, so that the nozzle 307 can achieve precise fire extinguishing. When the fire prevention device 3 detects a fire hazard in the power distribution cabinet, the second L-shaped plate 308 starts to operate, and the upward moving plate 309 moves upward along the track 305. Since the nozzle 307 is installed on the second L-shaped plate 308, the nozzle 307 moves upward accordingly. At the same time, the rotation function of the nozzle 307 also starts to play a role. The nozzle 307 adopts a rotatable design,Through the built-in rotating motor 205 gear transmission device, according to the position information of the fire source, multi-angle rotation is achieved. In this way, when the sprinkler head 307 moves upward close to the fire source, the spraying angle can be adjusted by rotation to achieve precise fire extinguishing of the fire source.

[0017] Working principle: When the device starts, the refrigerant is extracted by the condensation box 201 and enters the pipeline 202. The refrigerant flows through the pipeline 202 and absorbs the heat dissipated by the chassis 1 through the heat conduction plate 203. By absorbing the heat absorbed by the heat conduction plate 203 through the refrigerant, rapid heat dissipation of the chassis 1 is achieved, protecting the electrical equipment. The electrical equipment in the power distribution cabinet generates heat during operation. If the heat cannot be dissipated in time, the temperature of the equipment will rise. In a long-term high-temperature environment, the insulation performance of the electrical equipment will decline, accelerating equipment aging, shortening the service life of the equipment, and even possibly causing equipment failure or damage. Through heat dissipation by the refrigerant, the temperature inside the power distribution cabinet can be effectively controlled, protecting the electrical equipment and ensuring its stable and reliable operation. The motor 205 drives the reciprocating lead screw 206 to rotate. The cross-shaped spiral groove on the reciprocating lead screw 206 drives the cross-shaped plate 209 to move. The movement of the cross-shaped plate 209 drives the L-shaped plate one 210 to move. When the L-shaped plate one 210 moves, it will contact the hinged plate one 208, causing the hinged plate one 208 to swing after contact, realizing the hot and cold exchange cycle of the power distribution cabinet, enabling the power distribution cabinet to cool down quickly, and promoting the heat exchange efficiency. By driving the hinged plate one 208 to swing through the movement of the L-shaped plate one 210, the flow state of the heat exchange channel or heat exchange medium can be changed, etc., so that the hot air inside the power distribution cabinet can exchange heat more fully and quickly with the outside cold air or cooling medium, accelerating heat dissipation and improving the overall heat exchange efficiency, thereby achieving rapid cooling and ensuring that the temperature inside the power distribution cabinet always remains within a reasonable range.

[0018] The L-shaped plate 210 drives the fixed plate 301 to move. The movement of the fixed plate 301 drives the articulated plate 302 to move. The movement of the articulated plate 302 drives the fixed plate 303 to move. The movement of the fixed plate 303 drives the L-shaped plate 308 to move. The movement of the L-shaped plate 308 drives the nozzle 307 to move. The up and down movement of the nozzle 307 causes the nozzle 307 to move upward. The nozzle 307 is set to be rotatable, enabling the nozzle 307 to achieve precise fire extinguishing. When the fire prevention device 3 detects a fire hazard in the power distribution cabinet, the L-shaped plate 308 starts to operate, and the upward moving plate 309 moves upward along the track 305. Since the nozzle 307 is installed on the L-shaped plate 308, the nozzle 307 moves upward accordingly. At the same time, the rotation function of the nozzle 307 also starts to play a role. The nozzle 307 adopts a rotatable design. Through the built-in rotary motor 205 gear transmission device, according to the position information of the fire source, it can achieve multi-angle rotation. In this way, when the nozzle 307 moves upward close to the fire source, it can adjust the spraying angle by rotation to achieve precise fire extinguishing of the fire source. The fire extinguishing material in the fire bucket 306 is transported to the nozzle 307 through the pipeline 202. After the nozzle 307 is accurately positioned, it sprays out at the best angle and force to effectively extinguish the fire and minimize the damage caused by the fire to the power distribution cabinet. The movement of the L-shaped plate 308 drives the upward moving plate 309 to move. The movement of the upward moving plate 309 drives the baffle 310 to move, causing the baffle 310 to block the ventilation opening to prevent air from entering the power distribution cabinet to assist combustion. To prevent air from entering the power distribution cabinet to assist combustion, when a fire hazard signal is detected, the baffle 310 is pushed to quickly move to the position of the ventilation opening. The size of the baffle 310 precisely matches the ventilation opening, and it can tightly block the ventilation opening, effectively cutting off the passage of external air entering the power distribution cabinet, thereby reducing the oxygen content in the fire area and suppressing the further spread of the fire, minimizing the damage caused by the fire to the power distribution cabinet.

[0019] Please refer to Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, the anti-settlement device 4 includes an N-shaped plate 401, a roller 402, a rotating rod 403, a cross fan 404, and a filter box 405. The N-shaped plate 401 is fixedly connected to the top of the baffle 310, the filter box 405 is fixedly connected to the inner wall of the chassis 1, the rotating rod 403 is rotatably connected to the inner wall of the filter box 405, and the cross fan 404 is fixedly connected to the circumferential surface of the rotating rod 403. When the baffle 310 moves, it drives the N-shaped plate 401 to move. When the N-shaped plate 401 moves, it will contact the roller 402, causing the roller 402 to rotate by friction. The rotation of the roller 402 drives the rotation of the rotating rod 403, and the rotation of the rotating rod 403 drives the rotation of the cross fan 404, so that the cross fan 404 stirs the desiccant in the filter box 405 to maintain a dry environment. The main function of the desiccant is to absorb moisture in the air and reduce the humidity of the surrounding environment. In many scenarios that require moisture-proofing, such as buried outdoor power cabinets, through the stirring of the cross fan 404, the desiccant can be made to contact the air more fully and absorb moisture more efficiently, keeping the space dry and preventing items from being damaged, deteriorated, or moldy due to moisture. The roller 402 is fixedly connected to the front of the rotating rod 403. The anti-settlement device 4 further includes a horizontal plate 406, a concave plate 407, a clamping plate 408, and a second support plate 409. The horizontal plate 406 is fixedly connected to the right side of the baffle 310, the concave plate 407 is installed on the outer wall of the chassis 1, the clamping plate 408 is fixedly connected to the rear of the chassis 1, and the second support plate 409 is fixedly connected to the bottom of the concave plate 407. The right side of the N-shaped plate 401 contacts the inner wall of the chassis 1, and the outer wall of the horizontal plate 406 is slidably connected to the inner wall of the chassis 1. When the baffle 310 moves, it drives the horizontal plate 406 to move downward. The downward movement of the horizontal plate 406 drives the concave plate 407 to move downward. When the concave plate 407 moves downward, it is blocked by the clamping plate 408. The downward movement of the concave plate 407 drives the second support plate 409 to move. By the support of the second support plate 409, the settlement of the power distribution cabinet is prevented. The power distribution cabinet itself contains various electrical components, circuits, etc., and has a large weight. The second support plate 409 can disperse the overall weight of the power distribution cabinet over a larger area and transfer it to the ground or the foundation structure. Through this dispersion effect, the pressure borne per unit area is reduced, and the possibility of ground subsidence or damage to the foundation structure caused by excessive local pressure is reduced, thereby effectively preventing uneven settlement of the power distribution cabinet.

[0020] Working principle: The movement of the baffle 310 drives the movement of the N-shaped plate 401. When the N-shaped plate 401 moves, it will contact the roller 402, causing the roller 402 to rotate by friction. The rotation of the roller 402 drives the rotation of the rotating rod 403, and the rotation of the rotating rod 403 drives the rotation of the cross fan 404, causing the cross fan 404 to stir the desiccant in the filter box 405 to maintain a dry environment. The main function of the desiccant is to absorb moisture in the air and reduce the humidity of the surrounding environment. In many moisture-proof scenarios, such as in buried outdoor power cabinets, through the stirring of the cross fan 404, the desiccant can be more fully contacted with the air and absorb moisture more efficiently, keeping the space dry and preventing items from being damaged, deteriorated or mildewed due to moisture. The movement of the baffle 310 drives the cross plate 406 to move downward, and the downward movement of the cross plate 406 drives the concave plate 407 to move downward. The downward movement of the concave plate 407 is blocked by the clamping plate 408, and the downward movement of the concave plate 407 drives the movement of the second support plate 409. The second support plate 409 prevents the power distribution cabinet from settling. The power distribution cabinet itself contains various electrical components, circuits, etc. and is relatively heavy. The second support plate 409 can disperse the overall weight of the power distribution cabinet over a larger area and transfer it to the ground or the foundation structure. Through this dispersion effect, the pressure borne per unit area is reduced, and the possibility of ground subsidence or damage to the foundation structure caused by excessive local pressure is reduced, thus effectively preventing uneven settlement of the power distribution cabinet.

[0021] The present invention provides a buried outdoor safety power cabinet. There are many methods and ways to specifically implement this technical solution. The above description is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by using existing technologies.
