Description

Technical Field

[0001] This utility model relates to the field of ramming material screening technology, specifically an energy-saving cooling device for an American-style substation. Background Technology

[0002] American-style substations, also known as American transformer boxes, are generally not equipped with high-voltage metering in imported products because the electricity consumption per unit in the United States is relatively large and high-voltage metering is not used. Various instruments and distribution circuit breakers are not installed in the low-voltage compartments. Due to the limited usable space, only four low-voltage circuits can be distributed. High-voltage metering, low-voltage compensation, and multi-circuit distribution cannot be achieved in the product itself.

[0003] The prior art patent document with publication number CN220273120U provides an energy-saving cooling device for an American-style substation, including a box and a base. In use, the heat dissipation pipe is located inside the ground, which facilitates the absorption of heat from the heat dissipation pipe by the nearby soil. This is beneficial for absorbing the residual heat of the water, further reducing the heat of the water inside the heat dissipation pipe, and improving the cooling effect. In use, the intake fan and exhaust fan in the air inlet work to accelerate the circulation of external air and the air inside the American-style substation, which is beneficial for improving the cooling effect of the American-style substation. The water tank is placed on the ground, which is convenient for staff to carry out maintenance and replenish water, avoids staff climbing to heights, and reduces the difficulty of the work.

[0004] Although the device has many beneficial effects, it still has the following problems: During the use of the device, the soil position is fixed. When the soil exchanges heat with the heat dissipation pipe and the temperature rises, the cooling effect on the water inside the heat dissipation pipe becomes worse, making it difficult to cool. Secondly, the device has insufficient shock absorption during use. It is easily damaged by external impacts, resulting in transformer oil leakage. Improvements are needed. In view of this, we propose an energy-saving cooling device for American-style substations. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the issues mentioned above, such as the fixed soil position leading to reduced cooling effect on the water inside the heat dissipation pipe after heat exchange and temperature rise, resulting in poor cooling, insufficient shock absorption, and easy damage and leakage of transformer oil under external impact, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide an energy-saving cooling device for American-style substations, which facilitates the cooling of the cooling water inside the heat exchange tubes, provides good cooling effect for the internal equipment of American-style substations, facilitates the improvement of shock absorption effect, and avoids transformer oil leakage caused by external collision damage.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] An energy-saving cooling device for an American-style substation includes a substation body with a base at its bottom. A heat dissipation assembly, comprising heat sinks, is located at the bottom of the heat sink's sidewall. A water pump is mounted on the sidewall of the water pump, with a mounting frame at its output end. A heat exchange tube with multiple fins on its outer circumference is located on the inner sidewall of the mounting frame. Multiple fans are mounted on the inner sidewall of the mounting frame. A flexible hose is attached to the other end of the heat exchange tube, and a water delivery pipe is attached to the other end of the hose. Multiple nozzles are mounted on the sidewall of the water delivery pipe. A base plate is slidably connected to the bottom of the base's inner sidewall. Multiple grooves are formed on the top of the base plate, and shock-absorbing components are slidably connected inside the grooves. The water pump is electrically connected to an external power source. The water collection pool facilitates the collection of cooling water, preventing it from flowing into the substation's internal equipment and causing damage.

[0012] As a preferred embodiment of the energy-saving cooling device for an American-style substation according to this utility model, the vibration damping component includes a movable block. A spring is located on the side wall of the movable block within a groove, and a damper is located on the other side wall of the movable block within the groove. A first hinge seat is located at the top of the movable block, and a connecting rod is hinged to the first hinge seat. The other end of the connecting rod is hinged to a second hinge seat located at the bottom of the base. Multiple second hinge seats facilitate increased stability of the base, thereby improving the stability of the substation itself.

[0013] As a preferred embodiment of the energy-saving cooling device for an American-style substation according to this utility model, the heat sink has fixing plates on both sides of its top sidewall. A motor is mounted on the sidewall of each fixing plate, and a reciprocating screw is mounted at the motor's output end. A slider located on the top of the water supply pipe sidewall is threaded onto the outer circumference of the reciprocating screw. The motor is electrically connected to an external power source. The fixing plates facilitate the installation of the reciprocating screw and motor while preventing the slider from detaching.

[0014] As a preferred embodiment of the energy-saving cooling device for an American-style substation according to this utility model, the heat sink is made of copper-nickel alloy and is coated with thermally conductive silicone grease and bonded to the internal equipment of the substation body.

[0015] As a preferred embodiment of the energy-saving cooling device for an American-style substation according to this utility model, the slider sidewall is slidably connected to a limit rod, and the limit rod is fixedly connected to a fixing plate.

[0016] As a preferred embodiment of the energy-saving cooling device for an American-style substation according to this utility model, the size of the moving block matches the size of the groove, and the adjacent shock-absorbing components are arranged in opposite directions.

[0017] As a preferred embodiment of the energy-saving cooling device for an American-style substation according to this utility model, the substation body has louvers on its side wall and the top of the substation body is inclined.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of American-style substation's energy-saving cooling device exchanges heat through heat sinks that are in close contact with the internal equipment of the substation body. Cooling water is sprayed onto the surface of the heat sinks through nozzles on the side wall of the water supply pipe to cool them down. The cooling water falls into the water collection tank. The water pump is turned on to allow the cooling water to enter the heat exchange tubes. The fan is turned on to drive airflow to cool the heat exchange tubes. The fins improve the heat exchange efficiency. The cooled water is circulated from the hose into the water supply pipe for reuse, making it more energy-efficient and environmentally friendly.

[0021] This type of energy-saving cooling device for American-style substations causes the base to move downwards when the substation body is subjected to external force. This movement causes the second hinge seat to move downwards, which in turn causes the connecting rod to rotate and move the first hinge seat. This, in turn, causes the moving block to move outwards. The spring's rebound force then resets the moving block. The damper improves the shock absorption effect and prevents transformer oil leakage caused by collision damage. Attached Figure Description

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of an energy-saving cooling device for an American-style substation, including:

[0035] Please see Figures 1-5 This embodiment of an energy-saving cooling device for an American-style substation includes a substation body 1, a base 2 welded to the bottom of the substation body 1, a heat dissipation assembly 3 fixed to the side wall of the substation body 1, the heat dissipation assembly 3 including heat sinks 301, a water collection tank 302 welded to the bottom of the side wall of the heat sink 301, a water pump 303 fixed to the side wall of the water collection tank 302, a mounting frame 304 fixed to the output end of the water pump 303, a heat exchange tube 305 fixed to the inner side wall of the mounting frame 304, multiple fins 306 welded to the outer circumference of the heat exchange tube 305, multiple fans 307 threadedly connected to the inner side wall of the mounting frame 304, a flexible hose 308 fixed to the other end of the heat exchange tube 305, a water supply pipe 309 fixed to the other end of the flexible hose 308, and a water supply pipe 309 fixed to the side wall of the water supply pipe 309. There are multiple nozzles 310. A base plate 4 is slidably connected to the bottom of the inner wall of the base 2. Multiple grooves 5 are opened on the top of the base plate 4. Shock-absorbing components 6 are slidably connected inside the grooves 5. The water pump 303 is electrically connected to an external power supply. It exchanges heat with the internal equipment of the substation body 1 through the heat sink 301. Cooling water is sprayed onto the surface of the heat sink 301 through the nozzles 310 on the side wall of the water pipe 309 to cool it down. The cooling water falls into the water collection pool 302. The water pump 303 is turned on to allow the cooling water to enter the heat exchange tube 305. The fan 307 is turned on to drive the air flow to cool the heat exchange tube 305. The heat exchange efficiency is improved by the fins 306. The cooled water enters the water pipe 309 through the hose 308 for recycling, which is more energy-saving and environmentally friendly.

[0036] In some embodiments, the substation body 1 includes a variety of electrical and electronic components, such as a high-voltage compartment, a low-voltage compartment, a transformer body, a high-voltage load switch, and fuses. Due to space limitations, such prior art is not described in detail. The layout of such prior art can be reasonably adapted to this solution and will not affect the normal operation of this solution.

[0037] It is worth noting that, in order to improve the cleaning effect of the shock absorption component 6, the shock absorption component 6 specifically includes a moving block 601. A spring 602 is fixed on the side wall of the moving block 601 and located on the side wall of the groove 5. A damper 603 is fixed on the other side wall of the moving block 601 and located on the side wall of the groove 5. A first hinge seat 604 is fixed on the top of the moving block 601. A connecting rod 605 is hinged to the first hinge seat 604. The other end of the connecting rod 605 is hinged to a second hinge seat 606 located at the bottom of the base 2. When the bottom of the substation body 1 is subjected to external force, the base 2 moves downward, causing the second hinge seat 606 to move downward, thereby causing the connecting rod 605 to rotate and drive the first hinge seat 604 to move, which in turn causes the moving block 601 to move outward. The spring 602's rebound force drives the moving block 601 to reset. The damper 603 improves the shock absorption effect and avoids transformer oil leakage caused by collision damage.

[0038] Next, in order to make the cooling water spray more thorough, a fixing plate 311 is fixed on both sides of the top of the side wall of the heat sink 301. A motor 312 is fixed on the side wall of the fixing plate 311. A reciprocating screw 313 is fixed on the output end of the motor 312. A slider 314 located on the top of the side wall of the water supply pipe 309 is threaded to the outer circumference of the reciprocating screw 313. The motor 312 is electrically connected to an external power source. By turning on the motor 312, the reciprocating screw 313 is driven to rotate, thereby causing the slider 314 to drive the water supply pipe 309 to move back and forth, so that the cooling water is evenly sprayed on the surface of the heat sink 301.

[0039] Meanwhile, in order to improve the heat exchange effect, the heat sink 301 is made of copper-nickel alloy. The heat sink 301 is coated with thermal grease and bonded to the internal equipment of the substation body 1. The heat sink 301 made of copper-nickel alloy facilitates the improvement of heat exchange effect. The thermal grease has excellent heat resistance and thermal conductivity, ensuring the stability of the electrical performance of electronic instruments and meters.

[0040] Furthermore, to facilitate limiting the slider 314, specifically, the side wall of the slider 314 is slidably connected to a limit rod 315, which is fixedly connected to the fixed plate 311. Through the limit rod 315 fixedly connected to the fixed plate 311, the slider 314 is prevented from rotating with the reciprocating screw 313.

[0041] It is worth noting that, in order to improve stability, the size of the movable block 601 is matched with the size of the groove 5, and the adjacent shock-absorbing components 6 are set in opposite directions. The movable block 601, which is matched with the size of the groove 5, makes the movement of the movable block 601 more stable. The adjacent shock-absorbing components 6, which are set in opposite directions, make the substation body 1 more balanced.

[0042] Finally, to facilitate heat dissipation, specifically, the substation body 1 is equipped with louvers 7 on its side wall and the top of the substation body 1 is inclined. The louvers 7 facilitate airflow inside the substation body 1 and facilitate heat dissipation. The inclined top of the substation body 1 also facilitates rainwater to slide off and avoids rainwater accumulation.

[0043] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0044] The device or equipment models mentioned in this article may be as follows:

[0045] Water pump 303: IS65-50-160;

[0046] Motor 312: Y90S-2.

[0047] Combination Figures 1-5 The specific usage process of an energy-saving cooling device for an American-style substation according to this embodiment is as follows:

[0048] 1: When this device is used as an energy-saving cooling device for American-style substations, thermally conductive silicone grease is applied to the back of the heat sink 301 and it is bonded to the internal equipment of the substation body 1. The nozzle 310 sprays cooling water onto the surface of the heat sink 301 to cool it down. The cooling water falls into the water collection tank 302. The water pump 303 is started to allow the cooling water in the water collection tank 302 to enter the heat exchange tube 305. The fan 307 is started to drive airflow to cool the heat exchange tube 305. The cooled water enters the water supply pipe 309 from the hose 308 for recycling.

[0049] 2: When the substation body 1 is subjected to external force, the base 2 moves downward, causing the second hinge seat 606 to move downward and drive the connecting rod 605 to rotate, thereby causing the first hinge seat 604 to move and drive the moving block 601 to move outward. The rebound force of the spring 602 drives the moving block 601 to reset.

[0050] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
