[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0037] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a protection shell for a power transmission and transformation equipment adapted to extreme climate conditions, including a box-type transformer and its outer shell 1 for protecting the transformer coil. A heat dissipation port 2 is provided on the outer shell 1, and a remote terminal for monitoring the operating state of the box-type transformer is further included. A water response structure for dealing with water accumulation in rainy weather is provided on the outer shell 1;
[0038] The water-responsive structure includes a base 3 slidably disposed on the outer housing 1. The top of the base 3 includes an integrally formed side extension 301. An inner extension rod 21 driven to move upward by the accumulated water level is provided on the base 3. A pressure sensor 25 is fixedly connected to the side extension 301. An abutting plate 24 that is in extrusion contact with the pressure sensor 25 is fixedly connected to the inner extension rod 21 at a position corresponding to the pressure sensor 25.
[0039] A data receiving and processing module electrically connected to the abutting plate 24 is fixedly connected to the outer housing 1. The data receiving and processing module includes a wireless communication module that transmits the processed pressure signal result to a remote terminal.
[0040] A water-blocking assembly for blocking the heat dissipation port 2 according to the height of the accumulated water level is further provided on the base 3, and a rain accumulation measuring assembly for adjusting the triggering threshold of the water-blocking assembly according to the rainfall is provided on the outer housing 1.
[0041] As Figure 1 、 Figure 2 and Figure 9 shown, when the box-type transformer encounters extreme weather such as heavy rain and flooding, resulting in accumulated water around it, under the action of the water-blocking assembly, when the accumulated water depth reaches the first set depth, the heat dissipation port 2 can be blocked to prevent the accumulated water from entering the outer housing 1 through the heat dissipation port 2. Among them, the first set depth should be less than the horizontal height of the heat dissipation port 2 to facilitate timely blocking of the heat dissipation port 2.
[0042] At the same time, if the accumulated water reaches the first depth and continues to rise, as the accumulated water continues to rise, when the accumulated water reaches the second set depth, the abutting plate 24 fixedly provided at the end of the inner extension rod 21 contacts the pressure sensor 25, and subsequently, as the water level line rises, the pressure on the pressure sensor 25 increases, that is, the pressure value received by the pressure sensor 25 is proportional to the height of the water level line.
[0043] Among them, the pressure sensor 25 transmits the received pressure signal to the data receiving and processing module. The data receiving and processing module performs denoising, calibration, and contrast enhancement processing on the received pressure signal to ensure the accuracy and reliability of the signal, and transmits the processed signal to the remote terminal through the wireless communication module built in the data receiving and processing module. After receiving the signal, the remote terminal judges the danger level of the accumulated water according to the preset threshold. If the pressure signal exceeds the preset safety valve threshold, the system will automatically trigger an alarm and start a protection mechanism. The remote terminal can issue an instruction to cut off the power supply of the transformer by controlling the power-off switch inside the box-type transformer to prevent electrical failures and safety hazards caused by accumulated water.
[0044] Meanwhile, an accumulation measurement component for adjusting the trigger threshold of the water blocking component according to the rainfall is provided on the outer shell 1. The accumulation measurement component can measure the rainfall. Among them, the horizontal height of the base 3 can change with the change of the rainfall. The change mode is that the horizontal height of the base 3 is inversely proportional to the rainfall, that is, when the rainfall is larger, the horizontal height of the base 3 is lower.
[0045] Therefore, when the rainfall is too large, it means that the subsequent rising speed of the accumulated water is faster. Therefore, by reducing the horizontal height of the base 3, when the depth of the accumulated water has not reached the first set depth, the water blocking component can be triggered to operate and block the heat dissipation port 2. Similarly, by changing the rainfall, the thresholds of the first set depth and the second set depth are changed to cope with the phenomenon that the water level rises rapidly due to excessive rainfall, ensuring that in the case of a rapid rising speed of the water level, a timely response is made to ensure the safety of the equipment.
[0046] In one relatively preferred embodiment, the water blocking component includes a middle position sliding seat 4 provided on the base 3, and a longitudinal chute 5 for the middle position sliding seat 4 to slide vertically is opened on the base 3. A floating bladder 16 is fixedly connected below the middle position sliding seat 4;
[0047] One side of the middle position sliding seat 4 facing the heat dissipation port 2 is fixedly connected with an adapter plate 17, and a lateral sealing plate 18 corresponding to the position of the heat dissipation port 2 and in sliding contact with the outer shell 1 is fixedly connected to the adapter plate 17.
[0048] As Figure 1 - Figure 3 shown, a floating bladder 16 is fixedly arranged below the middle position sliding seat 4. When the water level of the accumulated water rises, the floating bladder 16 will float on the water level line of the accumulated water and move upward with the rising of the water level line, thereby driving the middle position sliding seat 4 thereon to move synchronously. Among them, both sides of the middle position sliding seat 4 are fixedly connected with a lateral sealing plate 18 through an adapter plate 17. The lateral sealing plate 18 is initially located below the heat dissipation port 2. With the upward movement of the floating bladder 16 and the middle position sliding seat 4, it gradually blocks the heat dissipation port 2 from bottom to top, and a certain length is reserved for the lateral sealing plate 18 in the vertical direction to ensure the blocking effect of the lateral sealing plate 18 on the heat dissipation port 2 when the water level of the accumulated water rises subsequently.
[0049] Among them, in order to prevent the accumulated water from flowing into the heat dissipation port 2 through the gap between the lateral sealing plate 18 and the outer shell 1, an annular rectangular groove 19 is opened on the edge of the lateral sealing plate 18 and on the side facing the outer shell 1. A rubber expansion water stop 20 fixedly connected to the lateral sealing plate 18 is arranged in the annular rectangular groove 19. An annularly arranged rubber expansion water stop 20 is provided at the joint edge of the lateral sealing plate 18 and the outer shell 1. When the rubber expansion water stop 20 contacts the accumulated water, it can absorb and expand, thereby improving the sealing performance between the lateral sealing plate 18 and the outer shell 1 to prevent the accumulated water from flowing into the outer shell 1 through the heat dissipation port 2.
[0050] Based on the water-blocking component embodiment, the base 3 is provided with an extension seat 6 that slides freely on the middle slide seat 4, and the extension seat 6 is provided with a receiving groove 22 for the inner extension rod 21 to slide vertically, and a pressure spring 23 is provided in the receiving groove 22, and the two ends of the pressure spring 23 are respectively fixedly connected to the extension seat 6 and the inner extension rod 21.
[0051] The middle slide 4 is provided with a rectangular groove for the extension seat 6 to slide vertically, a guide column 7 is fixedly connected to the lower part of the extension seat 6, and a stop block 9 is fixedly connected to the middle slide 4 for the guide column 7 to slide through, and the end of the stop block 9 away from the guide column 7 includes an integrally formed top inclined portion 10;
[0052] The outer circumference of the guide column 7 is sleeved with a return spring 8, and the two ends of the return spring 8 are fixedly connected to the top extension seat 6 and the blocking block 9 respectively;
[0053] The base 3 is provided with a directional component for limiting the vertical movement of the extension seat 6 .
[0054] like Figure 3 , Figure 4 and Figure 7 As shown, when the water level rises, the float 16 can drive the center slide 4 to move upward, wherein the directional component restricts the top extension seat 6. At this time, the top extension seat 6 will not move upward synchronously with the center slide 4, but will gradually shorten the distance between the blocking block 9 and the top extension seat 6, and cause the reset spring 8 to gradually undergo compression deformation. However, as the center slide 4 continues to rise, when the accumulated water reaches the second set depth, the directional component unlocks the restriction on the top extension seat 6. At this time, the reset spring 8 restores its elastic deformation and drives the top extension seat 6 to move upward, so as to prompt the inner extension rod 21 to move upward synchronously, and drive the pressure plate 24 to contact the pressure-bearing end of the pressure sensor 25.
[0055] At the same time, in the subsequent rising process of accumulated water, the top extension seat 6 continues to move upward following the middle slide 4, thereby gradually reducing the distance between the longitudinal slide 5 and the pressure sensor 25. At this time, the pressure plate 24 gradually retracts into the top extension seat 6, and drives the pressure spring 23 to undergo compression deformation, and the deformation amount is related to the water level. At this time, if the water level continues to rise, the pressure spring 23 further undergoes compression deformation, thereby causing the pressure on the pressure sensor 25 to gradually increase. The signal receiving and processing module analyzes and processes the received pressure signal, and transmits the processing result to the remote terminal. When the pressure signal exceeds the preset safety threshold, the power-off operation of the box-type transformer is completed to prevent electrical failures and safety hazards caused by accumulated water.
[0056] Further, the orientation component includes a side support plate 15 fixedly connected to the base 3. A swing rod 12 is rotatably mounted on the side support plate 15 about a fixed axis. One end of the swing rod 12 away from the side support plate 15 includes an end inclined portion 13 integrally formed and in sliding contact with the top inclined portion 10. A pointed block 11 is fixedly connected to the side of the top extension seat 6 facing the swing rod 12. A triangular top block 14 is fixedly connected to the swing rod 12 at a position corresponding to the pointed block 11.
[0057] The pointed block 11 and the triangular top block 14 are in pressing contact in the initial state.
[0058] As Figure 1 - Figure 5 As shown, when the pointed block 11 abuts against the triangular top block 14, as the accumulated water rises, the floating bladder 16 and the middle-position sliding seat 4 are driven to move upward. At this time, under the restriction of the triangular top block 14, the top extension seat 6 cannot move upward synchronously with the middle-position sliding seat 4. However, the horizontal height of the middle-position sliding seat 4 gradually rises, and the end inclined portion 13 in the swing rod 12 corresponds to the top inclined portion 10. After the two correspond, as the middle-position sliding seat 4 continues to rise, under the obstruction of the top inclined portion 10, the swing rod 12 can deflect in the vertical direction, so that the triangular top block 14 no longer restricts the pointed block 11.
[0059] At the same time, after the triangular top block 14 no longer abuts against the pointed block 11, the return spring 8 can restore its deformation and drive the top extension seat 6 and the inner extension rod 21 provided on its top to move upward until the pressing plate 24 contacts the pressure sensor 25. Therefore, after the accumulated water reaches the second set depth, the orientation component completes the unlocking process of the top extension seat 6, so that the pressing plate 24 can contact the pressure sensor 25, so that the pressure sensor 25 is subjected to a pressing force. And as the accumulated water rises later, the pressing force received by the pressure sensor 25 gradually increases. Through the change of the pressure signal value, the real-time change of the accumulated water depth is reflected, and then the danger level of the accumulated water is judged according to the preset threshold value, so as to make a response strategy for the box-type transformer in time.
[0060] It should be noted that a torsion spring for driving the swing rod 12 to return to the deflected position is provided on the side support plate 15. This torsion spring is an existing device and a technical means well-known to those skilled in the art, so it is not shown in the figure. Through the setting of the torsion spring, when the accumulated water recedes, the middle-position sliding seat 4 and the top extension seat 6 return to the initial position under the action of gravity, so that the swing rod 12 restricts the top extension seat 6 again to achieve the purpose of automatic reset.
[0061] Based on the embodiment of the orientation component, the product measurement component includes a positioning plate 30 fixedly connected to the outer housing 1. A vertical hollow column 27 slidably penetrates through the positioning plate 30. An open frame 26 is fixedly penetrated through the top of the vertical hollow column 27. The bottom of the vertical hollow column 27 is fixedly penetrated with the side extension 301. The vertical hollow column 27 includes a rain drainage cavity 28 for natural rainwater to fall.
[0062] A heavy pressure spring 29 is sleeved on the outer peripheral surface of the rain drainage cavity 28. The two ends of the heavy pressure spring 29 are respectively fixedly connected to the positioning plate 30 and the side extension 301.
[0063] As Figure 1 、 Figure 2 and Figure 8 shown, when there is a phenomenon of water accumulation line around the box-type transformer due to rainfall, rainwater is received through the open frame 26. Among them, the rainwater in the open frame 26 is naturally discharged through the rain drainage cavity 28 on the vertical hollow column 27, and the size of the rain drainage cavity 28 remains unchanged. Therefore, the discharge speed of the rainwater in the rain drainage cavity 28 is constant. When the rainfall is too large and the amount of rainwater entering the open frame 26 is greater than the amount of rainwater discharged, the rainwater in the open frame 26 continuously accumulates until it is full.
[0064] Meanwhile, as the rainwater in the open frame 26 gradually increases, under the action of the gravity of the received rainwater, the open frame 26 drives the base 3 to move downward through the vertical hollow column 27, thereby changing the initial height of the base 3, so that when the accumulated water is not at the first set depth, the water blocking component can be driven to operate, and thus the thresholds of the first set depth and the second set depth can be automatically adjusted according to different rainfall amounts. This adjustment method can cope with the water accumulation situation under different rainfall intensities, ensuring timely response in the case of a relatively fast rising water level and guaranteeing the safety of the equipment.
[0065] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
