DETAILED DESCRIPTION

[0038] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0039] See also Figures 1 to 9 The present invention provides a technical solution: a protective mechanism for a high and low voltage switch cabinet, comprising a main body 1, wherein the main body 1 is provided with an installation bin 11 and a cooling bin 12 distributed vertically, and a partition 13 is provided below the installation bin 11 to separate the cooling bin 12 from the upper and lower parts;

[0040] The main body 1 is divided into two compartments, an installation compartment 11 and a cooling compartment 12 , by a partition 13 . The installation compartment 11 is used to install relevant components of the switch cabinet, and the cooling components are installed in the cooling compartment 12 to cool the installation compartment 11 .

[0041] The installation chamber 11 is provided with a transformer 7, and the cooling chamber 12 is provided with a refrigerator 8;

[0042] The transformer 7 in the switch cabinet is installed in the installation chamber 11 , and a refrigerator 8 is installed in the cooling chamber 12 to cool the transformer 7 .

[0043] A ceiling 2, wherein the ceiling 2 is fixedly installed above the main body 1, the ceiling 2 is arranged in a triangular shape, and the ceiling 2 completely covers the upper part of the main body 1;

[0044] The ceiling 2 protects the main body 1 and blocks rain when the main body 1 is set in an open air environment. The triangular setting of the ceiling 2 allows rain to flow outward along both sides of the ceiling 2 to prevent rain from entering the main body 1.

[0045] A first water tank 3, which is disposed between the main body 1 and the ceiling 2, the first water tank 3 is connected to the top of the ceiling 2, and cooling pipes 33 for upward and downward circulation are installed on both sides of the bottom of the first water tank 3;

[0046] The first water tank 3 collects part of the rainwater that falls on the ceiling 2 , and circulates the collected rainwater to the side of the transformer 7 through the cooling pipe 33 for cooling.

[0047] A second water tank 4, wherein the second water tank 4 is installed in the cooling chamber 12, the second water tank 4 is connected to the lower side of the cooling pipe 33, and a conveying component for introducing the water in the second water tank 4 into the first water tank 3 is provided in the second water tank 4;

[0048] The water in the first water tank 3 is introduced into the second water tank 4 through the cooling pipe 33. Since the second water tank 4 is installed in the cooling chamber 12, close to the refrigerator 8, the water in the second water tank 4 is cooled so that the water maintains a cooling effect on the transformer 7 during the cooling cycle.

[0049] A push frame 5, wherein the push frame 5 is arranged on the outside of the cooling tube 33, and a spring 53 is arranged on the push frame 5. The push frame 5 pushes the cooling tube 33 to move inward under the elastic force of the spring 53;

[0050] Under the elastic force of the spring 53, the push frame 5 pushes the cooling pipe 33 inward, so that it is close to and squeezes the two sides of the transformer 7, and squeezes the transformer 7 to the middle of the installation chamber 11. The cooling pipe 33 is close to the outer walls of both sides of the transformer 7, so that the water flowing inside it can better absorb the heat generated by the transformer 7, thereby improving the cooling effect.

[0051] A spray assembly is installed on the top of the installation bin 11 to provide fire and explosion protection for the transformer 7 in the installation bin 11 .

[0052] Through the structure of the spray assembly, after the transformer 7 spontaneously ignites or explodes, the fire can be extinguished in time to prevent greater losses.

[0053] The four lower corners of the ceiling 2 are fixedly connected with support rods 21, and the bottom of the support rods 21 is fixedly connected to the upper outer side of the main body 1. Inlet pipes 22 are respectively provided on both sides of the ceiling 2. The inlet pipes 22 connect the upper and lower sides of the ceiling 2. A water inlet trough 23 is installed on the top of the inlet pipe 22. The water inlet trough 23 filters impurities other than rainwater. The inlet pipe 22 is vertically inserted into the first water tank 3.

[0054] Through the structure of the support rod 21, a distance is set between the ceiling 2 and the top of the main body 1, which is convenient for the first water tank 3 to be installed therebetween. Part of the rainwater is collected into the first water tank 3 through the inlet pipe 22, and water can be added manually when there is no rain to fill the evaporation of part of the cooling water caused by the high temperature inside the main body 1. The water inlet trough 23 filters the water entering the first water tank 3 to prevent some impurities from entering and causing blockage of the internal pipes.

[0055] A drain pipe 31 is fixedly connected to the upper side of the first water tank 3. The drain pipe 31 is horizontally arranged. The position of the drain pipe 31 is higher than the bottom of the inlet pipe 22. Flexible hoses 32 are respectively arranged at the four corners below the first water tank 3. The flexible hoses 32 penetrate into the upper part of the main body 1 and are connected to the upper end of the cooling pipe 33.

[0056] The water level in the first water tank 3 is limited by the structure of the drain pipe 31 to prevent the water level inside the first water tank 3 from being too high, causing water to overflow from the connection between the first water tank 3 and the inlet pipe 22 and enter the main body 1. The connection structure between the hose 32 and the cooling pipe 33 allows the cooling pipe 33 to move within a certain range below the first water tank 3.

[0057] The cooling pipe 33 is configured to be Y-shaped, the lower portion of the cooling pipe 33 passes through the partition 13, the lower end of the cooling pipe 33 is connected to the second water tank 4, the lower portion of the cooling pipe 33 is slidingly connected to the partition 13 and the second water tank 4 respectively, and a sealing assembly is provided at the connection portion between the cooling pipe 33 and the second water tank 4.

[0058] The cooling pipe 33 can slide horizontally so that the push frame 5 can push the cooling pipe 33 to move within a certain range and clamp and attach the transformer 7. The structure of the sealing component can ensure that the cooling pipe 33 and the second water tank 4 can still maintain sealing between the two during the sliding process, thereby preventing water from entering the cooling chamber 12 and causing equipment damage.

[0059] A rotating wheel 42 is provided below the connection between the second water tank 4 and one of the cooling pipes 33, and the rotating wheel 42 is fixedly mounted on a rotating shaft 41, and the rotating shaft 41 is rotatably connected to the second water tank 4, and a worm gear 43 is installed on the other side of the rotating shaft 41, and the worm gear 43 is arranged below another cooling pipe 33, and a worm 45 is provided on the side of the worm gear 43, and the worm gear 43 is meshed with the worm 45 for transmission, and a propulsion rod 44 is fixedly connected above the worm 45, and the propulsion rod 44 extends into the cooling pipe 33 on this side, and a first connecting rod 34 is fixedly connected below the cooling pipe 33 on this side, and a movable disk 46 is fixedly connected to the bottom of the first connecting rod 34, and the movable disk 46 is horizontally slidably connected to the second water tank 4, and the bottom of the worm 45 is mounted on the movable disk 46, and the worm 45 is rotatably connected to the movable disk 46.

[0060] In the process of water moving from the cooling pipe 33 on one side to the second water tank 4, the heat generated by the transformer 7 is heat exchanged, and the water flow entering the second water tank 4 has a downward acceleration, so that the water flow contacts the rotating wheel 42 and drives the rotating wheel 42 to rotate. During the rotation of the rotating wheel 42, the worm gear 43 is driven by the structure of the rotating shaft 41 to follow it to perform the same rotation. Since the worm gear 43 is meshed with the worm 45, the worm 45 rotates on the movable disk 46 and drives the propulsion rod 44 to rotate, and the water is transported upward from the bottom of the cooling pipe 33 on the other side, that is, the water cooled by the refrigerator 8 in the second water tank 4 is transported upward to the first water tank 3, so as to realize the cooling water circulation. The cooling pipe 33 on this side is connected to the movable disk 46 through the structure of the first connecting rod 34, so that during the movement of the cooling pipe 33, the propulsion rod 44 is driven to move, thereby avoiding the problem that the cooling pipe 33 cannot be moved due to the structural setting of the propulsion rod 44.

[0061] The push frame 5 is fixedly connected to the outer wall of the cooling tube 33, and a sleeve 51 is fixedly connected to the outer side of the push frame 5. The outer side of the sleeve 51 is sleeved on a fixing rod 52, and the fixing rod 52 is horizontally slidably connected to the sleeve 51. The outer end of the fixing rod 52 is fixedly connected to the inner wall of the installation bin 11. The spring 53 is arranged between the sleeve 51 and the fixing rod 52, and one end of the spring 53 is fixedly connected to the inner wall of the sleeve 51, and the other end of the spring 53 is fixedly connected to the end of the fixing rod 52.

[0062] Under the elastic force of the spring 53 , the sleeve 51 is pushed away from the fixing rod 52 , so that the push frame 5 always has a tendency to move toward the middle of the installation chamber 11 , so as to push the cooling pipe 33 to be close to the outer walls of the transformer 7 on both sides.

[0063] A water outlet pipe 35 is fixedly connected to the bottom of the first water tank 3. The water outlet pipe 35 penetrates into the top of the installation bin 11. The water outlet pipe 35 is communicated with the first water tank 3. The spray assembly includes a threaded pipe 61 screwed to the water outlet pipe 35. A connecting seat 6 is fixedly connected to the bottom of the threaded pipe 61. The upper outer side of the connecting seat 6 is sealed and connected to the bottom of the water outlet pipe 35.

[0064] A plurality of evenly distributed second connecting rods 62 are fixedly connected to the bottom of the connecting seat 6, a sputtering plate 63 is fixedly connected to the bottom of the second connecting rod 62, a lower positioning seat 64 is fixedly connected to the upper middle part of the sputtering plate 63, a ball groove is provided above the lower positioning seat 64, a baffle plate 65 is sleeved on the second connecting rod 62, the baffle plate 65 is vertically slidably connected to the second connecting rod 62, and the side walls of the baffle plate 65 and the sputtering plate 63 are both arranged to be serrated.

[0065] A sealing block 66 is fixedly connected to the top of the baffle 65, and the sealing block 66 is stuck in the middle of the connecting seat 6 and the threaded tube 61. A sealing ring is provided on the side wall of the sealing block 66, and the sealing block 66 is sealed and connected to the connecting seat 6 and the threaded tube 61 through the sealing ring. An upper positioning seat 67 is fixedly connected to the bottom of the baffle 65, and a conical groove is provided below the upper positioning seat 67. The upper and lower ends of a glass ball 68 are respectively stuck in the conical groove and the ball groove, and the glass ball 68 supports the baffle 65.

[0066] The connecting seat 6, the second connecting rod 62 and the splash plate 63 are an integral unit, which is installed below the water outlet pipe 35 through the threaded tube 61. The baffle plate 65 is slid upward to the highest point, so that the lower positioning seat 64 and the upper positioning seat 67 are separated from each other, and the glass ball 68 is moved between the ball groove of the lower positioning seat 64 and the cone groove of the upper positioning seat 67. The baffle plate 65 is loosened, so that the baffle plate 65 slides downward for a certain distance, and the cone groove abuts against the upper end of the glass ball 68, so that the glass ball 68 supports the baffle plate 65, keeps the sealing block 66 in the state of being retained in the connecting seat 6, so that the water in the first water tank 3 The water cannot flow downward. When the transformer 7 spontaneously ignites or explodes, the temperature in the installation chamber 11 rises sharply. After the temperature reaches a certain level, the glass ball 68 automatically explodes, and the baffle 65 loses support. Under the downward water pressure of the water outlet pipe 35, the sealing block 65 is flushed downward from the connecting seat 6 and the threaded tube 61, so that the baffle 65 slides vertically downward along the second connecting rod 62 to the lowest point. The water flows into the splash plate 63 and the baffle 65, and through the serrated structure of the side wall, the flushed water spreads outward and completely covers the installation chamber 11, thereby extinguishing the internal fire source.

[0067] A push rod 69 is fixedly connected to one side wall of the baffle 65 , and a power switch 14 is installed on the installation compartment 11 at the same side of the push rod 69 , and the lower end of the push rod 69 abuts against the upper end of the power switch 14 .

[0068] After the glass ball 68 bursts, the baffle 65 moves downward, driving the lever 69 downward. Since the downward impacting water flow has a large impact force, the lever 69 drives the power switch 14 to turn off, that is, the switch cabinet is powered off in time after an accident occurs in the switch cabinet to avoid greater losses.

[0069] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
