A distribution box for electrical automation

Abstract

This invention discloses a distribution box for electrical automation, relating to the technical field of distribution boxes for electrical automation. The distribution box includes a box body, with an air inlet mesh frame fixed to the left side and an air outlet mesh frame fixed to the right side. A fan is fixed to the inner wall of the air inlet mesh frame. This distribution box is equipped with a protective device. When a large amount of snow accumulates on the top plate, the weight causes the top plate to move downwards, allowing a pressing block to press against the inclined surface of the top of an L-shaped blocking block. This prevents the L-shaped blocking block from blocking the air inlet, allowing the hot air to be discharged from the air outlet mesh frame to enter the air inlet pipe through the air inlet. The hot air then enters the connecting holes on the top plate, heating the snow on the top plate and causing it to melt quickly. This solves the problem of snow accumulation on the top plate causing deformation and hindering heat dissipation within the device.

Description

Technical Field

[0001] This invention relates to the field of electrical automation distribution boxes, specifically to an electrical automation distribution box. Background Technology

[0002] Distribution boxes are divided into power distribution boxes, lighting distribution boxes, and metering boxes, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] A power distribution cabinet with good protection effect, patent publication number CN219477427U, includes a power distribution cabinet body and two sets of dustproof nets. A protective component is provided on the upper surface of the power distribution cabinet body. Fixing components are provided on the upper and lower surfaces of both ends of the power distribution cabinet body. Connecting plates are fixedly installed on the upper and lower surfaces of one end of each of the two sets of dustproof nets. One end of each connecting plate is located within the fixing component. This application utilizes the protective component on the upper surface of the power distribution cabinet body to activate air cooling, allowing internal heat to dissipate through heat dissipation holes, thus extending the service life of the electrical components in the power distribution cabinet body. The connecting plates fixedly installed on one end of the dustproof nets allow operators to install the connecting plates into the fixing components, securing them and covering the heat dissipation holes with the dustproof nets, preventing dust from entering the holes.

[0004] When existing distribution boxes are in use, snowfall can cause a large amount of snow to accumulate on top of them. The snow can only melt slowly, and if the distribution box is subjected to the pressure of snow for a long time, it may cause the equipment to deform. In addition, the snow covering the top of the distribution box will hinder heat dissipation, causing the internal temperature of the distribution box to rise and affecting the normal operation of the equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a distribution box for electrical automation, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a distribution box for electrical automation, comprising a box body, an air inlet mesh frame fixed on the left side of the box body, an air outlet mesh frame fixed on the right side of the box body, a fan fixed on the inner wall of the air inlet mesh frame, a movable plate penetrating through the top of the box body and slidably connected at the penetration point, a top plate fixed on the top of the movable plate, a support spring fixed on the inner wall of the box body, the bottom of the support spring fixed to the bottom of the movable plate, a protective device for protecting the box body provided on the side wall of the box body, an auxiliary device for improving air intake provided inside the air outlet mesh frame, and a turning device for facilitating the melting of ice and snow provided on the top of the top plate; The protective device includes a squeezing block, an L-shaped shielding block, a transmission spring, an air inlet, an air inlet pipe, a connecting hole, a water storage tank, a water inlet pipe, and a condensation plate. The squeezing block is fixed to the bottom of the top plate, the air inlet is located on the housing, the L-shaped shielding block passes through the air inlet and is slidably connected at the point of penetration, one side of the transmission spring is fixed to the side wall of the housing, and the other side of the transmission spring is fixed to the bottom of the L-shaped shielding block. When there is a large amount of snow on the top plate, the weight of the top plate will increase, causing the top plate to move the moving plate downwards. The moving plate will then stretch the support spring. When the top plate moves downwards, the inclined surface of the squeezing block will press against the inclined surface of the L-shaped shielding block, causing the L-shaped shielding block to be subjected to squeezing force and move, thus stretching the transmission spring.

[0007] According to the above technical solution, the connecting hole is opened on the top plate, the air inlet pipe is fixed at the bottom of the top plate, the air inlet pipe passes through the top of the box and is slidably connected at the penetration point, the air inlet pipe is connected to the air inlet hole, and when the L-shaped blocking block is away from the fan, the L-shaped blocking block can not block the air inlet hole, so that the hot air flow from the air outlet mesh frame enters the air inlet hole and the air inlet pipe, and the air inlet pipe discharges the hot air into the connecting hole. Since the top plate is made of metal, the top plate can be heated so that the ice and snow on the top of the top plate can melt quickly.

[0008] According to the above technical solution, the water storage tank is located at the top of the top plate, and an inlet pipe is fixed at the bottom of the water storage tank, with the water storage tank connected to the inlet pipe. A condenser plate is fixed at the back of the box, with the bottom of the inlet pipe connected to the top of the condenser plate. An outlet pipe is fixed at the bottom of the condenser plate. Melted ice and snow can allow liquid to enter the water storage tank, and the melted ice water can enter the condenser plate through the inlet pipe. The condenser plate is fixed at the back of the box, thereby cooling the inside of the box.

[0009] According to the above technical solution, the auxiliary device includes a bending block, a support block, a rotating rod, a guide plate, a gear, a rack, a fixing block, a connecting spring, a striking block, a rotating block, a protrusion, and a transmission block; the bending block is fixed to the side wall of the L-shaped shielding block, the support block is fixed to the inner wall of the air outlet mesh frame, the rotating rod passes through the support block and is rotatably connected at the point of penetration, and the guide plate is fixed to the outer wall of the rotating rod.

[0010] According to the above technical solution, the gear is fixed to the outer wall of the rotating rod, the rack is fixed to the side wall of the bending block, the bottom of the rack meshes with the outer wall of the gear, the rotating block is fixed to the end point of the rotating rod, and the protrusion is fixed to the outer wall of the rotating block. When the L-shaped blocking block moves, it can drive the bending block to move, causing the bending block to drive the rack to move, causing the rack to drive the gear to rotate clockwise, thereby driving the rotating rod and the guide plate to rotate clockwise, so that the guide plate rotates to fit against the mesh plate of the air outlet mesh frame.

[0011] According to the above technical solution, the fixing block is fixed to the inner wall of the air outlet mesh frame, the striking block is slidably installed on the inner wall of the air outlet mesh frame, one side of the connecting spring is fixed to the side wall of the fixing block, the other side of the connecting spring is fixed to the side wall of the striking block, the transmission block is slidably installed on the bottom inner side of the striking block, the top of the auxiliary spring is fixed to the inner wall of the striking block, and the bottom of the auxiliary spring is fixed to the top of the transmission block. When the rotating rod rotates clockwise, it can drive the rotating block to rotate, which can drive the protrusion to rotate, thereby causing the protrusion to press against the transmission block, causing the transmission plate to move, which can drive the striking block to move towards the fixing block, compressing the connecting spring. When the protrusion rotates to the point where it no longer contacts the transmission block, the connecting spring can drive the striking block to reset.

[0012] According to the above technical solution, the turning device includes a transmission plate, rollers, disintegrating blocks, crushed blocks, a fixed plate, an extrusion rod, and a wave groove; the transmission plate is slidably installed on the side wall of the top plate, the fixed plate is fixed to the back of the box, and the wave groove is opened on the side wall of the fixed plate. When the top plate moves downward, the transmission plate can drive the extrusion rod to move in the wave groove, so that the extrusion rod is subjected to extrusion force and moves back and forth in the wave groove, thereby driving the transmission plate to move back and forth, causing the disintegrating blocks to move back and forth on the top of the top plate.

[0013] According to the above technical solution, the crushing block is rotatably mounted on the transmission plate, the roller is fixed to the outer wall of the crushing block, the bottom of the roller is in contact with the top of the top plate, and the crushing block is fixed to the outer wall of the crushing block. When the crushing block moves, the roller moves on the top of the top plate. Due to friction, the roller can drive the crushing block to rotate.

[0014] This invention provides a distribution box for electrical automation. It has the following advantages: (1) By setting up a protective device, when a large amount of snow is attached to the top of the top plate, the top plate will become heavier and move downwards. This allows the squeezing block to squeeze the inclined surface of the top of the L-shaped shielding block, thereby causing the L-shaped shielding block to not block the air inlet. This allows the hot air to be discharged from the air outlet frame to enter the air inlet pipe through the air inlet, and the hot air to enter the connection hole opened on the top plate. The hot air can heat the snow on the top of the top plate, so that the snow can melt quickly. This solves the problem of snow accumulating on the top plate for a long time, causing the top plate to deform and hindering the heat dissipation inside the device. In addition, the melted ice water flows into the condenser plate through the water inlet pipe. The condenser plate can quickly cool the inside of the box, which can improve the operating efficiency of the equipment, thereby reducing energy consumption and achieving the effect of saving electricity.

[0015] (2) By setting up an auxiliary device, when the L-shaped blocking block moves, it can drive the bending block to move, and the rack can move on the gear, thereby driving the gear and the rotating rod to rotate clockwise, so that the guide plate rotates to the bottom of the air inlet and is inclined, thus facilitating the gas to enter the air inlet along the guide plate, solving the problem that hot air is not easy to enter the air inlet, resulting in low snow melting efficiency; and when the rotating rod rotates, it can drive the rotating block and the protrusion to rotate, and through the cooperation of the transmission block and the auxiliary spring, the striking block can strike the mesh plate of the air outlet frame back and forth, thereby knocking off the impurities attached to the mesh plate, preventing impurities from blocking the mesh plate of the air outlet frame, which would reduce the efficiency of hot air exhaust and thus reduce the efficiency of hot air entering the air inlet, thus solving the problem of slow snow melting.

[0016] (3) By setting up a turning device, when the top plate moves downward, it can drive the transmission plate and the extrusion rod to move downward, so that the extrusion rod moves back and forth in the wave groove. This allows the transmission plate to drive the breaking block to move back and forth in the snow in the top plate, thereby turning over and breaking up the snow that has solidified together. This increases the contact area between the snow and the top of the heated top plate, allowing the snow to absorb heat more effectively and thus accelerate the melting speed. When the breaking block moves back and forth, it can cause the roller to move on the top plate. Due to friction, the roller will rotate, which can drive the breaking block to rotate. This allows the tip of the crushed block to break the ice layer at the bottom of the snow, thus preventing a whole ice layer from adhering to the top of the top plate, which would affect heat conduction and make it difficult for heat to enter the snow, thereby reducing the melting efficiency of the snow. Moreover, the structure of the broken ice layer is looser, and the heat conduction is smoother, which helps to transfer heat quickly. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-10One embodiment of the present invention is as follows: an electrical automation distribution box includes a box body 1, an air inlet mesh frame 2 fixed on the left side of the box body 1, an air outlet mesh frame 3 fixed on the right side of the box body 1, a fan 4 fixed on the inner wall of the air inlet mesh frame 2, a movable plate 5 passing through the top of the box body 1 and slidably connected at the passage, a top plate 6 fixed on the top of the movable plate 5, and a support spring 7 fixed on the inner wall of the box body 1, the bottom of the support spring 7 being fixed to the bottom of the movable plate 5; that is, one end of the support spring 7 is fixed to the inner wall of the box body 1, and the other end is fixed to the bottom of the movable plate 5.

[0021] The side wall of the housing 1 is equipped with a protective device to protect the housing 1; the protective device includes a compression block 81, an L-shaped shielding block 82, a transmission spring 83, an air inlet 84, an air inlet pipe 85, a connecting hole 86, a water storage tank 87, a water inlet pipe 88, and a condensation plate 89; the compression block 81 is fixed to the bottom of the top plate 6, the air inlet 84 is opened on the housing 1 and communicates with the air outlet mesh frame 3, the L-shaped shielding block 82 passes through the air inlet 84 and is slidably connected at the through point, one side of the transmission spring 83 is fixed to the side wall of the housing 1, and the other side of the transmission spring 83 is fixed to the bottom protrusion of the L-shaped shielding block 82, which is connected to the bottom protrusion of the housing 1. The side walls of body 1 are clamped together to form an installation space, in which the transmission spring 83 is located; the connecting hole 86 is opened on the top plate 6, the air inlet pipe 85 is fixed to the bottom of the top plate 6, the air inlet pipe 85 is connected to the connecting hole 86, the air inlet pipe 85 passes through the top of the box body 1 and is slidably connected at the penetration point, the air inlet pipe 85 is connected to the air inlet hole 84, the water storage tank 87 is opened on the top of the top plate 6, the bottom of the water storage tank 87 is fixed with the water inlet pipe 88, and the water storage tank 87 is connected to the water inlet pipe 88; the back of the box body 1 is fixed with the condenser plate 89, the bottom of the water inlet pipe 88 is connected to the top of the condenser plate 89, and the bottom of the condenser plate 89 is fixed with the water outlet pipe.

[0022] Because the bottom of the extrusion block 81 is set as an inclined surface and the top of the L-shaped blocking block 82 is set as an inclined surface, when a large amount of snow accumulates on the top of the top plate 6, the extrusion block 81 will be moved downward by the extrusion pressure on the top plate 6. This allows the extrusion block 81 to extrude the inclined surface on the top of the L-shaped blocking block 82, thereby preventing the L-shaped blocking block 82 from blocking the air inlet 84. This allows the hot air to be discharged from the air outlet frame 3 to enter the air inlet pipe 85 through the air inlet 84, and the hot air to enter the connection hole 86 opened on the top plate 6. Since the top plate 6 is made of metal, heating the top plate 6 and the hot air can heat the snow on the top of the top plate 6, allowing the snow to melt quickly. This solves the problem of snow accumulating on the top plate 6 for a long time, causing the top plate 6 to deform and hindering the heat dissipation inside the device. Furthermore, the melted ice water flows into the condenser plate 89 through the water inlet pipe 88. The condenser plate 89 can quickly cool the inside of the box 1, which can improve the operating efficiency of the equipment, thereby reducing energy consumption and achieving the effect of saving electricity. The water in the condenser plate 89 can be drained away through the water outlet pipe.

[0023] In this embodiment, when the distribution box is used outdoors, the fan 4 is activated to draw cold air from the outside into the box 1 for heat dissipation. The air that has absorbed heat is then discharged through the exhaust mesh frame 3. In snowy weather, a large amount of snow accumulates on the top plate 6 of the box 1, increasing its weight. This weight causes the moving plate 5 to move downwards, stretching the support spring 7. As the top plate 6 moves downwards, it also causes the pressing block 81 to move downwards, pressing the inclined surface at the bottom of the pressing block 81 against the inclined surface at the top of the L-shaped blocking block 82, thus compressing the L-shaped blocking block. The L-shaped blocking block 82 is compressed and thus moves away from the fan 4. When the L-shaped blocking block 82 moves away from the fan 4, the transmission spring 83 is stretched, causing the L-shaped blocking block 82 to move out into the air inlet 84. This prevents the air inlet 84 from being blocked, allowing some of the hot air discharged from the air outlet frame 3 to enter the air inlet 84. The hot air then moves upward into the air inlet pipe 85 and into the connecting hole 86, thereby heating the top plate 6. The heated top plate 6 can transfer heat to the snow, allowing the snow on the top plate 6 to melt quickly. The hot air entering the connecting hole 86 can be discharged through the through hole at the bottom of the top plate 6.

[0024] When the melted snow turns into liquid, the liquid flows into the water storage tank 87, and then the liquid is discharged from the water inlet pipe 88 connected to the bottom of the water storage tank 87 into the condenser plate 89, thereby enabling the condenser plate 89 to dissipate heat into the box 1. When the snow on the top plate 6 melts, the weight of the top plate 6 becomes lighter, so the support spring 7 is in a stretched state. This causes the support spring 7 to drive the moving plate 5 and the top plate 6 to move upward, so that the pressing block 81 does not press the L-shaped blocking block 82. Because the transmission spring 83 is in a stretched state, it will drive the L-shaped blocking block 82 to reset, so that the L-shaped blocking block 82 blocks the air inlet 84, preventing hot air from entering the top plate 6. This prevents hot air from being discharged into the top plate 6 even when there is no snow on it, which would affect the heat dissipation inside the box 1.

[0025] Please see Figures 1-10Based on the above embodiments, in another embodiment of the present invention, an auxiliary device for improving air intake is provided inside the air outlet mesh frame 3, and a turning device for facilitating the melting of ice and snow is provided on the top of the top plate 6. The auxiliary device includes a bending block 91, a support block 92, a rotating rod 93, a guide plate 95, a gear 94, a rack 96, a fixing block 99, a connecting spring 911, a striking block 910, a rotating block 97, a protrusion 98, a transmission block 912, and an auxiliary spring 913; the bending block 91 is fixed to the side wall of the L-shaped blocking block 82, the support block 92 is fixed to the inner wall of the air outlet mesh frame 3, the rotating rod 93 passes through the support block 92 and is rotatably connected at the point of penetration, the guide plate 95 is fixed to the outer wall of the rotating rod 93, and the gear 94... The rack 96 is fixed to the side wall of the bending block 91, and the bottom of the rack 96 meshes with the outer wall of the gear 94. The rotating block 97 is fixed to the end point of the rotating rod 93. The protrusion 98 is fixed to the outer wall of the rotating block 97. The fixing block 99 is fixed to the inner wall of the air outlet frame 3. The striking block 910 is slidably installed on the inner wall of the air outlet frame 3. One side of the connecting spring 911 is fixed to the side wall of the fixing block 99, and the other side of the connecting spring 911 is fixed to the side wall of the striking block 910. The transmission block 912 is slidably installed on the inner bottom of the striking block 910. The top of the auxiliary spring 913 is fixed to the inner wall of the striking block 910, and the bottom of the auxiliary spring 913 is fixed to the top of the transmission block 912.

[0026] When the L-shaped blocking block 82 moves, it can cause the bending block 91 to move, and the rack 96 to move on the gear 94. This causes the gear 94 and the rotating rod 93 to rotate clockwise, making the guide plate 95 inclined to the bottom of the air inlet 84. This facilitates the air to enter the air inlet 84 through the guide plate 95, solving the problem that hot air cannot easily enter the air inlet 84, resulting in low snow melting efficiency. Furthermore, when the rotating rod 93 rotates, it can drive the rotating block 97 and the protrusion 98 to rotate. Through the cooperation of the transmission block 912 and the auxiliary spring 913, the striking block 910 can strike the mesh plate of the air outlet mesh frame 3 back and forth, thereby knocking off the impurities attached to the mesh plate and preventing the impurities from blocking the mesh plate of the air outlet mesh frame 3, which would reduce the efficiency of hot air exhaust and thus reduce the efficiency of hot air entering the air inlet 84, thus solving the problem of slow snow melting.

[0027] The turning device includes a transmission plate 101, rollers 106, a disintegrating block 105, a crushing block 107, a fixing plate 102, a pressing rod 104, and a wave groove 103. The transmission plate 101 is slidably mounted on the side wall of the top plate 6, the fixing plate 102 is fixed to the back of the housing 1, the wave groove 103 is opened on the side wall of the fixing plate 102, the disintegrating block 105 is rotatably mounted on the transmission plate 101, the rollers 106 are fixed to the outer wall of the disintegrating block 105, the bottom of the rollers 106 is in contact with the top of the top plate 6, and the crushing block 107 is fixed to the outer wall of the disintegrating block 105.

[0028] When the top plate 6 moves downward, it can drive the transmission plate 101 and the extrusion rod 104 to move downward, so that the extrusion rod 104 moves back and forth in the wave groove 103, thereby enabling the transmission plate 101 to drive the dispersing block 105 to move back and forth in the snow in the top plate 6, thereby turning over and dispersing the snow that has condensed together, increasing the contact area between the snow and the top of the heated top plate 6, so that the snow can absorb heat more effectively, thereby accelerating the melting speed. Furthermore, when the breaking block 105 moves back and forth, it enables the roller 106 to move on the top plate 6. As a result, the roller 106 rotates due to friction. The breaking block 105 is square, and the center point of the breaking block 105 and the center point of the roller 106 are the same circle. When the roller 106 rotates, it drives the breaking block 105 to rotate. Multiple sets of crushing blocks 107 are arranged linearly on the breaking block 105. When the breaking block 105 drives the multiple sets of crushing blocks 107 to rotate, the tips of the crushing blocks 107 can break the ice layer at the bottom of the snow. This prevents a whole block of ice from adhering to the top of the top plate 6, which would affect heat conduction and make it difficult for heat to enter the snow, thus reducing the snow melting efficiency. Moreover, the structure of the broken ice layer is looser, and heat conduction is smoother, which helps to transfer heat quickly.

[0029] In this embodiment, when the L-shaped blocking block 82 moves away from the fan 4, it causes the bending block 91 to move, which in turn causes the rack 96 to move. The rack 96 then moves on the gear 94, causing it to rotate clockwise. When the gear 94 rotates clockwise, the rotating rod 93 causes the guide plate 95 to rotate clockwise. When the guide plate 95 rotates to its position against the surface of the exhaust mesh frame 3, it guides the hot air from the exhaust mesh frame 3, allowing it to smoothly enter the air inlet 8 through the guide plate 95. In step 4, when the rotating rod 93 rotates clockwise, it causes the rotating block 97 to rotate clockwise. When the rotating block 97 rotates to the point where the protrusion 98 contacts the plane of the transmission block 912, the protrusion 98 presses the transmission block 912 to move to the right, causing the transmission block 912 to move the striking block 910 to the right, thus compressing the connecting spring 911. When the protrusion 98 rotates to the point where it no longer contacts the transmission block 912, the connecting spring 911 is in a compressed state, causing the connecting spring 911 to reset the striking block 910, causing the striking block 910 to strike the air vent. Specifically, on the surface of the mesh plate of frame 3, the striking block 910 slides towards the fixed block 99 on the inner wall of the air outlet mesh frame 3, and slides in the opposite direction to strike the mesh plate during reset, thereby knocking off the impurities attached to the mesh plate. Multiple sets of protrusions 98 contact the transmission block 912, allowing the transmission block 912 to drive the striking block 910 to strike the mesh plate back and forth. When the L-shaped blocking block 82 approaches the fan 4 for reset, it causes the L-shaped blocking block 82 to move the bending block 91 to the left, thereby causing the rack 96 to move on the gear 94, driving the gear 94 to rotate counterclockwise. When the needle rotates, the rotating rod 93 drives the guide plate 95 to rotate counterclockwise, making the guide plate 95 rotate to a horizontal state, thus facilitating the discharge of hot air from the exhaust mesh frame 3. When the rotating rod 93 drives the rotating block 97 to rotate counterclockwise, the protrusion 98 will press against the inclined surface of the transmission block 912. The elastic coefficient of the transmission spring 83 is ten times that of the elastic coefficient of the auxiliary spring 913, which allows the protrusion 98 to press the transmission block 912 upward, compressing the auxiliary spring 913, so that the protrusion 98 can rotate to the left side of the transmission block 912, preventing the striking block 910 from moving.

[0030] When the top plate 6 moves downward, it drives the transmission plate 101 downward, which in turn drives the pressing rod 104 downward. The pressing rod 104 moves within the corrugated groove 103 in the fixed plate 102, allowing it to move back and forth. This, in turn, drives the transmission plate 101 to move left and right, causing the dispersing block 105 to move back and forth across the snow accumulation on the top of the top plate 6, thus breaking up and dispersing the snow. When the pressing rod 104 pushes the snow away from the inlet pipe 88 within the corrugated groove 103, it... The transmission plate 101 can drive the breaking block 105 away from the water inlet pipe 88, so that the roller 106 can rub against the top plate 6 to reverse, thereby causing the breaking block 105 to reverse, so that the crushed block 107 on the breaking block 105 can rotate downward to break the ice layer at the bottom of the snow. When the extrusion rod 104 is squeezed in the wave groove 103 and moves closer to the water inlet pipe 88, the roller 106 can move closer to the water inlet pipe 88 on the top plate 6, so that the roller 106 rotates forward, thereby driving the breaking block 105 and the crushed block 107 to rotate forward and reset, so as to carry out the next crushing operation.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
