Description

Technical Field

[0001] This invention relates to the field of transformer technology, and specifically discloses a waterproof transformer for building engineering. Background Technology

[0002] Waterproof transformers used in construction projects typically refer to transformers installed in damp or potentially water-infiltrating environments, requiring special waterproofing measures to ensure their safe and reliable operation.

[0003] In construction projects, especially in outdoor or underground environments, transformers are often at risk of being submerged by rainwater. Traditional transformers are usually installed in fixed locations and cannot automatically change their position when the water level rises. Once they encounter heavy rain or floods, they are easily submerged, causing internal electronic components and coils to become damp and damaged. This makes it difficult to protect the internal coils or electronic components, resulting in serious economic losses and safety hazards. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a waterproof transformer for building engineering, so as to solve the problem that the transformer in the prior art cannot automatically change the position of the transformer when the water level rises, making it difficult to protect the internal coils or electronic components.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] The aforementioned waterproof transformer for building engineering includes a housing, with two sets of support frames at the bottom of the housing. A filling cavity is opened inside the support frame, and the filling cavity is filled with polymer material particles. A filter plate is fixedly installed on one side of the filling cavity, and a water inlet is opened on the side of the filling cavity near the filter plate. A sealing plate is slidably installed inside the water inlet, and the sealing plate is used to seal the water inlet.

[0007] Two sets of cavities are formed within the two side walls of the outer shell, each corresponding to a filling cavity. A movable plate is slidably disposed within each cavity. Several electric push rods are fixedly disposed at the top of the movable plate, and the tops of the electric push rods are fixedly connected to the top of the cavity. Several support rods are fixedly disposed at the bottom of the movable plate, and the bottoms of the support rods penetrate the bottom wall of the cavity and are fixedly connected to the top of the support frame. An extension groove is formed at the bottom of the support rod, which communicates with the filling cavity. A switch is fixedly disposed at the top of the extension groove, and the switch is electrically connected to the electric push rods. The switch is used to control the electric push rods.

[0008] Furthermore, a number of first compression springs are fixedly installed at the top of the sealing plate, a number of floats are fixedly installed on the side of the sealing plate away from the filling cavity, and a number of float openings are provided on the side wall of the support frame near the sealing plate, with all of the floats passing through the openings of the support frame.

[0009] Furthermore, a connector is fixedly installed on the top of the inner walls on both sides of the outer shell, and a compression groove is provided on the side of the connector away from the cavity. Two sets of pressure rods are slidably installed on the upper and lower parts of the compression groove near the cavity, and the two sets of pressure rods pass through the top and bottom of the connector respectively.

[0010] Furthermore, a threading groove is provided through the inside of the pressure rod, and a second compression spring is sleeved on the outer surface of the pressure rod. One end of the second compression spring is fixedly connected to the pressure rod, and the other end of the second compression spring is fixedly connected to the inner wall of the compression groove. The opposite sides of the two pressure rods abut against each other.

[0011] Furthermore, the wire-passing grooves opened in the two sets of pressure rods are connected, and wires are installed through and fixedly installed in the two sets of wire-passing grooves, and the wires are fixedly connected to the two sets of wire-passing grooves by bolts.

[0012] Furthermore, an extrusion block is slidably disposed in the extrusion groove. The upper and lower sides of the extrusion block near the end of the pressure rod are inclined, and the opposite sides of the two sets of pressure rods near the extrusion block are inclined. The upper and lower sides of the extrusion block near the end of the pressure rod abut against the opposite side of the pressure rod near the extrusion block.

[0013] Furthermore, a plurality of pull ropes are fixedly provided at one end of the extrusion block near the cavity, and the end of the pull rope away from the extrusion block passes through the inner wall of the outer shell and is fixedly connected to the top of the moving plate.

[0014] Furthermore, two sets of ventilation grilles are fixedly installed on both side walls of the outer shell without cavities, and four sets of movable slots are respectively opened on the side walls of the outer shell in conjunction with the four sets of ventilation grilles, and sealing grilles are slidably installed in the movable slots.

[0015] Furthermore, the top of the sealing grid is provided with a pressure groove, which is inclined in the whole. At both ends of the two sets of extrusion blocks, four sets of extrusion rods are fixedly provided in conjunction with the four sets of pressure grooves. The extrusion rods are slidably disposed in the pressure grooves and can extrude pressure on the inner wall of the pressure grooves.

[0016] Furthermore, a sealing gasket is fixedly provided on the side of the sealing grille near the ventilation grille, and the sealing gasket is used to seal the ventilation grille.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention, by setting up an electric push rod, a moving plate, and a support rod, enables the electric push rod, in conjunction with the moving plate and support rod, to raise the outer casing containing electronic components and coils when the water level rises. This prevents water from entering the outer casing from the bottom, thus avoiding damage to the electronic components and coils inside the casing.

[0019] 2. By setting a sealing plate and a float, when the water level rises, the float can drive the sealing plate to rise, thereby automatically opening the water inlet and allowing water to enter the filling cavity and come into contact with the polymer material particles. The polymer material particles expand when they come into contact with water, squeezing the switch, which in turn can automatically control the operation of the electric push rod.

[0020] 3. By setting up a squeezing block and a pull rope, the pull rope can drive the squeezing block to move during the process of the outer shell rising, so that the two sets of pressure rods that are in contact with each other move to their opposite sides, thereby disconnecting the wires fixedly connected in the two sets of wire grooves and stopping the transformer from working.

[0021] 4. By setting up a sealing grid, an extrusion rod, and a pressure groove, the present invention allows the extrusion rod to squeeze the pressure groove during the movement of the extrusion block, causing the sealing grid to move downward and automatically closing the opening on the ventilated grid, thereby preventing water from damaging the electronic components and coils inside the housing through the ventilated grid.

[0033] The present invention will now be described and illustrated in detail with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figure 1-8 As shown, the waterproof transformer for building construction includes a housing 1. Two sets of support frames 2 are provided at the bottom of the housing 1. A filling cavity 201 is provided inside the support frame 2. The filling cavity 201 is filled with polymer material particles. A filter plate 202 is fixedly provided on one side of the filling cavity 201. A water inlet 203 is provided on the side of the filling cavity 201 near the filter plate 202. A sealing plate 204 is slidably provided inside the water inlet 203. The sealing plate 204 is used to seal the water inlet 203.

[0036] Two sets of cavities 101 are formed in the two side walls of the outer shell 1, respectively, to accommodate two sets of filling cavities 201. A movable plate 102 is slidably arranged inside the cavity 101. Several electric push rods 103 are fixedly arranged at the top of the movable plate 102. The top of the electric push rods 103 is fixedly connected to the top of the cavity 101. Several support rods 104 are fixedly arranged at the bottom of the movable plate 102. The bottom of the support rods 104 penetrates the bottom wall of the cavity 101 and is fixedly connected to the top of the support frame 2. An extension groove 105 is formed at the bottom of the support rod 104. The extension groove 105 is connected to the filling cavity 201, and a switch 106 is fixedly arranged at the top of the extension groove 105. The switch 106 is electrically connected to the electric push rods 103 and is used to control the electric push rods 103.

[0037] A plurality of first compression springs 205 are fixedly installed at the top of the sealing plate 204. A plurality of floats 206 are fixedly installed on the side of the sealing plate 204 away from the filling cavity 201. The support frame 2 is provided with openings of the floats 206 close to the side wall of the sealing plate 204. All of the floats 206 pass through the openings of the support frame 2.

[0038] With the above setup, when a flood arrives, the rising water level can cause the float 206 to rise, which in turn causes the fixedly connected sealing plate 204 to rise. After the sealing plate 204 rises a certain distance, the inlet 203 is opened. At this time, water can pass through the inlet 203 and be filtered by the filter plate 202 before entering the filling cavity 201 and contacting the polymer material particles. When the polymer material particles come into contact with the water, they will expand rapidly. Some of the expanded polymer material particles enter the extension groove 105 and squeeze the switch 106. When the switch 106 is squeezed, it can control the electric push rod 103 to start working. The output end of the electric push rod 103 pushes the moving plate 102 and squeezes the top of the moving plate 102 and the cavity 101. Since the moving plate 102 is fixedly connected to the top of the support frame 2 through the support rod 104, the electric push rod 103 can push the outer shell 1 to rise relative to the moving plate 102, thereby moving the outer shell 1 away from the water surface and preventing water from entering the outer shell 1 and damaging the electronic components and coils.

[0039] The top of the inner walls on both sides of the outer shell 1 is fixedly provided with a connector 3, and a compression groove 301 is provided on the side of the connector 3 away from the cavity 101. Two sets of pressure rods 302 are slidably provided on the upper and lower parts of the compression groove 301 near the cavity 101, and the two sets of pressure rods 302 pass through the top and bottom of the connector 3 respectively.

[0040] The pressure rod 302 has a through-hole groove 303, and a second compression spring 307 is sleeved on the outer surface of the pressure rod 302. One end of the second compression spring 307 is fixedly connected to the pressure rod 302, and the other end of the second compression spring 307 is fixedly connected to the inner wall of the compression groove 301. The opposite sides of the two pressure rods 302 abut against each other.

[0041] The wire-passing grooves 303 in the two sets of pressure rods 302 are connected, and wires are fixedly installed through the two sets of wire-passing grooves 303. The wires are fixedly connected to the two sets of wire-passing grooves 303 by bolts.

[0042] An extrusion block 304 is slidably disposed in the extrusion groove 301. The upper and lower sides of the extrusion block 304 near the end of the pressure rod 302 are inclined, and the opposite sides of the two sets of pressure rods 302 near the extrusion block 304 are also inclined. The upper and lower sides of the extrusion block 304 near the end of the pressure rod 302 abut against the opposite side of the pressure rod 302 near the extrusion block 304.

[0043] A plurality of pull ropes 305 are fixedly provided at one end of the extrusion block 304 near the cavity 101. The end of the pull rope 305 away from the extrusion block 304 passes through the inner wall of the outer shell 1 and is fixedly connected to the top of the moving plate 102.

[0044] With the above settings, when the moving plate 102 rises a certain distance relative to the outer shell 1 until the pull rope 305 is tightened, the pull rope 305 no longer extends. As the outer shell 1 continues to rise, the pull rope 305 can pull the squeezing block 304 to move closer to the pressure rod 302. When the squeezing block 304 moves, it can squeeze the inclined surfaces of the two sets of pressure rods 302 through the inclined surfaces on the upper and lower sides, causing the two sets of pressure rods 302 to move to their opposite sides and gradually separate, thereby disconnecting the wires fixedly connected in the two sets of wire grooves 303, cutting off the circuit, and avoiding short circuits.

[0045] Two sets of ventilation grilles 107 are fixedly installed on both sides of the outer shell 1 where there is no cavity 101, and four sets of movable grooves 108 are opened on the side walls of the outer shell 1 to cooperate with the four sets of ventilation grilles 107. A sealing grille 109 is slidably installed in the movable groove 108.

[0046] The top of the sealing grid 109 is provided with a pressure groove 110, which is inclined in the whole. At both ends of the two sets of extrusion blocks 304, four sets of extrusion rods 306 are fixedly installed in conjunction with the four sets of pressure grooves 110. The extrusion rods 306 are slidably installed in the pressure grooves 110, and the extrusion rods 306 can extrude pressure on the inner wall of the pressure grooves 110.

[0047] A sealing gasket is fixedly provided on the side of the sealing grille 109 near the ventilation grille 107, and the sealing gasket is used to seal the ventilation grille 107.

[0048] With the above configuration, when the extrusion block 304 moves, it can drive the extrusion rod 306 fixedly connected to it to move. When the extrusion rod 306 moves, it can extrude the inner wall of the pressure groove 110, thereby driving the sealing grid 109 to move downward. After the movement, the sealing grid 109 is misaligned with the ventilated grid 107, thereby sealing the opening on the ventilated grid 107 and preventing external water from entering the housing 1 through the ventilated grid 107 and damaging the electronic components and coils.

[0049] Working principle and process:

[0050] During operation, when the water level at the location rises, it causes the float 206 to rise, which in turn causes the sealing plate 204 to rise, automatically opening the water inlet 203. Water filtered by the filter plate 202 enters the filling chamber 201. The polymer particles expand upon contact with water and enter the extension groove 105, squeezing the switch 106. When the switch 106 is squeezed, it controls the electric push rod 103 to start working. The electric push rod 103 pushes the outer shell 1 to rise relative to the moving plate 102, thereby automatically raising the height of the outer shell 1, keeping it away from the water surface, and preventing water from entering the outer shell 1 and damaging the electronic components and coils. When the moving plate 102 rises a certain distance until the pull rope 305 is tightened, as the outer shell 1 continues to rise, the pull rope 305 can... The pressing block 304 is pulled to move closer to the pressure rod 302, and then the inclined surfaces on the upper and lower sides of the pressing block 304 press the inclined surfaces on opposite sides of the two sets of pressure rods 302, causing the two sets of pressure rods 302 to move to opposite sides and gradually separate, thereby disconnecting the wires fixedly connected in the two sets of wire grooves 303, cutting off the circuit, stopping the transformer from working, and avoiding a short circuit. At the same time, when the pressing block 304 moves, it can drive the pressing rod 306 to move, thereby pressing the inner wall of the pressure groove 110, causing the sealing grid 109 to move downward and close the opening on the vent grid 107, preventing external water from entering the outer casing 1 through the vent grid 107 and damaging the electronic components and coils.
