Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical cabinets, especially to the technical field of outdoor electrical cabinets for water conservancy and hydropower users, in particular to an outdoor safety electrical cabinet for water conservancy and hydropower. BACKGROUND

[0002] The electrical cabinet is a closed box or cabinet for centralized installation and protection of electrical components, and is the core component of power distribution, motor control, circuit protection and automation systems, and is widely used in various fields such as industry, commerce, construction and infrastructure. The electrical cabinet for water conservancy and hydropower has different design requirements due to its harsh application environment. For example, the Chinese patent with application number 2020230261514 proposes an outdoor electrical cabinet for water conservancy and hydropower engineering. The outer contour of the upper part of the electrical cabinet body is sequentially embedded with a first motor switch and a second motor switch from left to right, and dust screens are fixedly installed on both sides of the cabinet wall. The inside bottom of the electrical cabinet body is fixedly connected with a water tank, and one electrically driven exhaust fan is fixedly installed on the lower part of each wall. Two motors rotate to dissipate heat from different directions, and the water in the water tank is also evaporated to cool the inside of the electrical cabinet, preventing high temperature from damaging internal electrical components. The rain and snow are blocked by the rainproof baffle and the inclined plate, improving the overall service life of the electrical cabinet. The dust screens on both sides can effectively prevent dust from entering, solving the problem of the electrical cabinet in outdoor operating environment. For example, the Chinese patent with application number 202510538509.X proposes an outdoor electrical cabinet convenient to install, which includes a mounting base, the top of which is fixedly connected with an electrical cabinet box, the top of which is fixedly connected with a water storage bin, the inner wall of which is fixedly connected with a filter screen, the bottom of which is connected with a water storage bin, and the bottom of which is connected with a first water pipe. Rainwater can be collected and filtered, and the electrical cabinet box can be water-cooled to improve the cooling effect of the equipment and clean the filter screen to prevent excessive impurities on the top of the filter screen from causing blockage and affecting the filtering efficiency of the filter screen. However, the current outdoor electrical cabinet, especially when used in the field of water conservancy and hydropower, still has some shortcomings, such as: The outdoor electrical cabinet for water conservancy and hydropower is generally installed in the area of buildings with different functions such as water retaining, water releasing, water taking, power generation and navigation. The installation surface of these building areas is generally provided with structures such as slopes. The electrical cabinet needs to be installed after the ground is treated, which not only increases the construction difficulty, but also changes the original design of the area, affecting the use of water conservancy and hydropower. Although the current outdoor electrical cabinet has been optimized in terms of rain and water resistance, the air in the water conservancy and hydropower engineering area is humid and contains a large amount of water molecules, which can easily cause condensation in the interior of the electrical cabinet, affecting the safety of internal components. Most electrical cabinets currently use internal water storage for fire response. However, when a small amount of water is used to extinguish a fire in an electrical cabinet, it can actually make the fire more serious, causing a large number of cables to short-circuit and exacerbating the losses.

[0003] Therefore, we propose an outdoor safety electrical cabinet for water conservancy and hydropower projects to address the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide an outdoor safety electrical cabinet for water conservancy and hydropower, in order to solve the problems mentioned in the background art, such as the inconvenience of installation of current outdoor electrical cabinets for water conservancy and hydropower, and the inadequacy of means to cope with humid air and special situations such as fire.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an outdoor safety electrical cabinet for water conservancy and hydropower, comprising: an outer shell and an inner shell integrally fixed therein, wherein a top cover is fixedly installed on the top of the outer shell; Also includes: A connecting plate is fixedly connected to the corner between the outer shell and the inner shell, forming a through-groove between them.

A ventilation groove is provided between the heat dissipation fins and through the back of the inner shell. A fan is installed at the bottom of the inner shell. An air outlet groove corresponding to the inside and outside of the fan is opened at the bottom of the outer shell. A base plate is fixedly installed on the top inner side of the inner shell, and a fire extinguishing agent is filled between the inner shell and the base plate.

[0006] Furthermore: an outer stop door and an inner stop door are rotatably mounted on the front sides of the outer shell and the inner shell respectively; a vertical plate is fixedly fixed on the inner side of the inner shell; a horizontal plate for mounting components is fixedly connected to the inner side of the vertical plate; and wire holes are opened on the sides of the outer shell and the inner shell.

[0007] Furthermore: the top surface of the top cover is angled backward, the air intake slots are equally spaced on the bottom front surface of the top cover, a fixing bracket is fixedly installed at one end of the inside of the top cover, and a push bracket is detachably installed at the other end of the inside of the top cover. The top end of the mounting bracket is correspondingly inserted and engaged with the fixing bracket, and the end of the mounting bracket is correspondingly engaged with the top end of the push bracket.

[0008] Furthermore: a fixing cylinder is provided above the mounting bracket and fixed to the inner bottom surface of the top cover. A pressure rod is connected to the bottom end of the inner part of the fixing cylinder, and a spring is connected between the fixing cylinder and the pressure rod.

[0009] Furthermore: a fixing plate is fixedly installed on the inner top of the inner shell, the bottom plate is fixedly connected to the bottom surface of the fixing plate, through holes are evenly opened inside the bottom plate, a diaphragm covering the through holes is attached to the top surface of the bottom plate, and a high-pressure gas tank communicating with the enclosed space between the inner shell and the bottom plate is installed on the top surface of the inner shell.

[0010] Furthermore, a placement plate is rotatably mounted on the bottom inner side of the inner barrier door, and a limiting block is provided on the inner side of the placement plate that is fixed integrally with the inner barrier door. The rotation angle range of the placement plate is 0-90°.

[0011] Furthermore, a support rod is inserted and connected to the bottom of the fixing groove, and the bottom end of the support rod is fixed to the mounting surface with bolts.

[0012] Furthermore, the bottom of the support rod is provided with through holes at equal intervals, and the support rod is fixedly connected to the outer shell with corresponding bolts.

[0013] Furthermore: a slot is provided on the inner side of the top of the support rod, a float plate is connected to the outer side of the support rod, a slot is provided on the side of the float plate that corresponds to the support rod, a retaining plate is provided inside the slot that is elastically connected to the side wall of the float plate, the retaining plate and the slot are correspondingly engaged, an airbag is installed on the bottom surface of the float plate, and an air pump located on the side of the float plate is connected to the outer side of the airbag.

[0014] Furthermore, a lifting rod is inserted and connected to the top of the fixing groove for top hoisting.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: the outdoor safety electrical cabinet for water conservancy and hydropower is easy to install horizontally, can stably ventilate and dissipate heat, can be used in response to the humid air in water conservancy, reduces internal condensation, and is easy to use for fire prevention, thereby improving the safety and reliability of the electrical cabinet. 1. This solution includes a fixing groove and a support rod. The outer shell, inner shell, and connecting plate are integrally fixed to the side to form the fixing groove. The support rod can be inserted and connected at the bottom through the fixing groove. By adjusting the insertion height of the support rod, the installation height of the outer shell can be adjusted to adapt to different safety position requirements. 2. This solution includes a mounting bracket, a honeycomb moisture-absorbing plate, and an air inlet. After the mounting bracket is installed inside the top cover, the honeycomb moisture-absorbing plate is pressed against the air inlet. The air entering the shell is absorbed by the honeycomb moisture-absorbing plate and then blown obliquely and evenly into the top surface of the shell through the air inlet. This reduces the amount of moisture entering the interior of the shell. Furthermore, the even airflow allows for the use of the self-heating of the internal components to absorb residual heat from the air, thus reducing condensation. 3. This solution is equipped with heat dissipation fins, which can draw out the heat inside the inner shell. The top of the heat dissipation fins is flush with the top surface of the inner shell, so that the air entering the top of the inner shell can come into contact first. If the air is humid and cold, condensation will be generated and flow down along the heat dissipation fins, preventing moisture from entering the interior of the inner shell. 4. This design includes ventilation slots, a fan, and an exhaust slot. When the fan is activated, air is easily drawn into the interior of the inner shell through the air inlet slot, honeycomb moisture-absorbing plate, air inlet hole, and ventilation slot. The air is then exhausted through the corresponding fan and exhaust slot, which enhances the ventilation and heat dissipation effect. 5. This solution includes a base plate, diaphragm, extinguishing agent, and high-pressure gas cylinder. A cavity is formed between the inner shell and the base plate to fill the extinguishing agent. When a fire breaks out inside the inner shell, the high-pressure gas cylinder blows air into the cavity, causing the diaphragm to rupture at the corresponding through-hole in the base plate and spraying out the extinguishing agent for fire extinguishing. 6. This solution includes a float plate, slots, and airbags. The float plate is fixed to the bottom of the outer casing and connected to the inside of the support rod. In the event of flooding, the airbags are inflated by an air pump to make the float plate float, which in turn causes the outer casing to float along the support rod, thus protecting the electrical cabinet. 7. This solution includes a lifting rod, which is inserted into the top of the fixing slot, enabling the entire electrical cabinet to be hoisted, reducing the impact of moisture and flooding.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figures 1-15 The present invention provides the following technical solution: An outdoor safety electrical cabinet for water conservancy and hydropower includes: an outer shell 1, an inner shell 2, a connecting plate 3, an outer door 4, an inner door 5, a top cover 6, a vertical plate 7, a horizontal plate 8, a wire hole 9, a fixing groove 10, a support rod 11, an air inlet groove 12, a mounting bracket 13, a honeycomb moisture-absorbing plate 14, an air inlet 15, a fixing bracket 16, a push bracket 17, a fixing cylinder 18, a pressure rod 19, a spring 20, heat dissipation fins 21, a ventilation groove 22, a mesh plate 23, a fan 24, a partition strip 25, an air outlet groove 26, a fixing plate 27, a bottom plate 28, a diaphragm 29, a fire extinguishing agent 30, a high-pressure gas tank 31, a placement plate 32, a limiting block 33, a floating plate 34, a slot 35, a locking plate 36, a locking groove 37, an air pump 38, an air bag 39, and a hanging rod 40. Among them: such as Figures 1-10 In the case, the inner shell 2 is integrally fixed inside the outer shell 1, and the top cover 6 is fixedly installed on the top of the outer shell 1. The connecting plate 3 is fixedly connected to the corner between the outer shell 1 and the inner shell 2, and the two enclose each other to form a fixed groove 10 that runs vertically through. The air inlet groove 12 is opened on the bottom front end of the top cover 6. The mounting bracket 13 is detachably installed inside the top cover 6. The honeycomb moisture-absorbing plate 14 is provided inside the mounting bracket 13. The bottom surface of the honeycomb moisture-absorbing plate 14 is in contact with the air inlet hole 15 opened on the top surface of the outer shell 1. The heat dissipation fins 21 are integrated and protruded to the back of the inner shell 2. The tops of the heat dissipation fins 21 are in contact with each other. A ventilation groove 22 is provided between the heat dissipation fins 21 and extends through the back of the inner shell 2. A fan 24 is installed at the bottom of the inner shell 2. An air outlet groove 26 corresponding to the inside and outside of the fan 24 is opened at the bottom of the outer shell 1. The bottom plate 28 is fixedly installed on the top of the inner side of the inner shell 2. Fire extinguishing agent 30 is filled between the inner shell 2 and the bottom plate 28.

[0020] In specific application scenarios, the outer shell 1 and inner shell 2 are integrally fixed together by the connecting plate 3, forming an overall double-layer structure to enhance its structural protection performance. Simultaneously, a fixing groove 10 is formed between the outer shell 1, inner shell 2, and connecting plate 3, allowing for adjustable installation with feet. During operation, an air inlet groove 12 is opened at the bottom of the top cover 6 integrally fixed to the top of the outer shell 1, allowing air to enter from the air inlet groove 12 towards the top of the outer shell 1. Meanwhile, an installed mounting bracket 13 is arranged inside the top cover 6, which contains a honeycomb moisture-absorbing plate 14. The honeycomb moisture-absorbing plate 14 allows the humid air to enter. The air absorbs moisture and enters the space between the outer shell 1 and the inner shell 2 through the air inlet 15 at the top of the outer shell 1. The air inlet 15 is set at an angle at the top of the outer shell 1, and its angle of inclination gradually increases from the center to both sides, so as to ensure that the air enters the inner top of the outer shell 1 evenly through the air inlet 15. The air enters the inner shell 2 and blows to the top of the inner shell 2 through the air inlet 15. Under the influence of the self-heating of the internal components, the surface of the inner shell 2 comes into contact with the colder air outside, which will cause condensation. Since the top edge of the inner shell 2 is symmetrically fixed with partition strips 25, the condensation can be prevented from flowing outward. Meanwhile, a heat dissipation fin 21 is integrally formed on the back of the inner shell 2. The complete fit between the top of the heat dissipation fin 21 and the top surface of the inner shell 2 allows the condensation to flow down through the heat dissipation fin 21 under the blowing of the inclined wind. At the same time, the heat dissipation fin 21 absorbs the self-heat inside the inner shell 2 and comes into contact with the cold and humid air inside, further actively generating condensation. This prevents the cold and humid air from entering the interior of the inner shell 2 and affecting the components. The processed air enters the interior of the inner shell 2 through the ventilation slot 22 opened on the inner surface of the inner shell 2. With the continuous operation of the fan 24, the air at the top can be blown to the bottom and blown out through the fan 24 to the air outlet slot 26 for air circulation and heat dissipation. In addition, a base plate 28 is fixed on the top of the inner shell 2, and fire extinguishing agent 30 is filled between the base plate 28 and the inner shell 2. This not only maintains the temperature stability of the top surface of the inner shell 2 by absorbing the self-heat of the components through the fire extinguishing agent 30, ensuring stable handling of cold air, but also allows the fire extinguishing agent 30 to be sprayed out through the internal perforation of the base plate 28 in the event of a fire for fire extinguishing purposes.

[0021] The above technical solution can maintain the overall structural strength of the electrical cabinet, facilitate the handling of humid and cold air in the water conservancy and hydropower environment, avoid the impact of internal condensation on components, ensure heat dissipation, cope with fire hazards, and enhance safety performance.

[0022] Among them: such as Figure 1 , Figure 3 and Figure 4 In the case, an outer stop door 4 and an inner stop door 5 are rotatably installed on the front sides of the outer shell 1 and the inner shell 2, respectively. A vertical plate 7 is fixedly fixed on the inner side of the inner shell 2. A horizontal plate 8 for mounting components is fixedly connected to the inner side of the vertical plate 7. Wire holes 9 are opened on the sides of the outer shell 1 and the inner shell 2. A placement plate 32 is rotatably installed on the bottom of the inner side of the inner stop door 5. A limiting block 33 is fixedly integrated with the inner stop door 5 on the inner side of the placement plate 32. The rotation angle range of the placement plate 32 is 0-90°.

[0023] In specific application scenarios, the outer door 4 and inner door 5, which are rotatably installed on the front side of the outer shell 1 and inner shell 2, and the glass window embedded inside them, facilitate closed observation. The vertical plate 7 and horizontal plate 8 installed vertically and horizontally inside the inner shell 2 facilitate the installation and fixation of internal components. At the same time, when the inner door 5 is opened, the placement plate 32 rotates inside the inner door 5. When the placement plate 32 rotates horizontally, the limiting block 33 blocks the placement plate 32, so that tools can be placed using the placement plate 32 to facilitate installation.

[0024] The above technical solution facilitates overall internal installation, tool placement, and internal closed-loop observation and use.

[0025] Among them: such asFigure 5 , Figure 6 and Figure 7 In the case, the top surface of the top cover 6 is set at an angle to the rear. The air intake slots 12 are opened at equal intervals on the bottom front end of the top cover 6. A fixing bracket 16 is fixedly installed at one end of the interior of the top cover 6, and a push bracket 17 is detached and installed at the other end of the interior of the top cover 6. The top end of the mounting bracket 13 is correspondingly inserted and engaged with the fixing bracket 16, and the end end of the mounting bracket 13 is correspondingly engaged with the top end of the push bracket 17. A fixing cylinder 18 is fixed on the bottom surface of the interior of the top cover 6 above the mounting bracket 13. A pressure rod 19 is connected to the bottom end of the interior of the fixing cylinder 18, and a spring 20 is connected between the fixing cylinder 18 and the pressure rod 19.

[0026] In specific application scenarios, when the mounting bracket 13 is installed, the top of the mounting bracket 13 engages with the fixing bracket 16 fixed to the bottom of the inner side of the top cover 6. After the top is engaged, the push bracket 17 is engaged with the top cover 6. At this time, the top of the push bracket 17 engages with the end of the mounting bracket 13. The push bracket 17 is connected to the top cover 6 by a snap-fit, ensuring the overall fixation. After installation, the pressure rod 19 set at the top of the mounting bracket 13 pops out from the fixing cylinder 18 under the elastic action of the spring 20, and presses down on the mounting bracket 13 to ensure the fit between the honeycomb moisture-absorbing plate 14 inside the mounting bracket 13 and the air inlet 15. The bottom of the pressure rod 19 is rounded to prevent the mounting bracket 13 from getting stuck when it is inserted.

[0027] The above technical solution facilitates the overall installation of the mounting bracket 13 and ensures a stable fit between the honeycomb moisture-absorbing plate 14 and the air inlet 15, thereby ensuring the treatment of humid and cold air.

[0028] Among them: such as Figure 5 , Figure 6 , Figure 9 and Figure 10 In the middle, a fixing plate 27 is fixedly installed on the top inner side of the inner shell 2, and a bottom plate 28 is fixedly connected to the bottom surface of the fixing plate 27. The bottom plate 28 has through holes evenly opened inside, and a diaphragm 29 covering the through holes is attached to the top surface of the bottom plate 28. A high-pressure gas tank 31 communicating with the enclosed space between the inner shell 2 and the bottom plate 28 is installed on the top surface of the inner shell 2.

[0029] In specific application scenarios, the fixing plate 27 is integrally fixed to the inner shell 2, and the base plate 28 is fixedly connected to the fixing plate 27 by screws. When a fire occurs inside the inner shell 2, high-pressure air is introduced into the space between the base plate 28 and the inner shell 2 through the high-pressure gas tank 31. Under the action of high-pressure gas, the diaphragm 29 attached to the top surface of the base plate 28 ruptures at the position of the through hole inside the base plate 28, so that the fire extinguishing agent 30 can be sprayed out through the through hole for timely fire extinguishing.

[0030] The above technical solution facilitates structural installation, can cope with internal fires, and improves safety performance.

[0031] Among them: such as Figure 1 , Figure 2 , Figure 4 , Figure 11 and Figure 15 In the middle, a support rod 11 is inserted and connected to the bottom of the fixing groove 10. The bottom end of the support rod 11 is fixed to the mounting surface with bolts. The bottom of the support rod 11 is provided with through holes at equal intervals. The support rod 11 is fixed to the outer shell 1 with corresponding bolts. A hanging rod 40 is inserted and connected to the top of the fixing groove 10 for top hoisting. In specific application scenarios, by inserting a support rod 11 into the bottom of the outer casing 1, the support rod 11 can extend and retract inside the fixing groove 10, and be fixed with bolts through the through holes at the appropriate position, so that the support rod 11 is fixedly connected to the outer casing 1, and its bottom is fixed to the use surface. Alternatively, a hanger 40 can be inserted into the top of the fixing groove 10, and the hanger 40 can be fixed to the outer casing 1 with bolts, so that the hanger 40 can be fixed to the fixed installation surface, which is convenient for installation and use.

[0032] By adopting the above technical solution, the outer shell 1 can be erected and installed by the support rod 11, and the outer shell 1 can be hoisted and used by the lifting rod 40, so as to ensure that the outer shell 1 can be installed and used in different locations and environments.

[0033] Among them: such as Figures 11-14 In the middle, a slot 37 is provided on the inner side of the top of the support rod 11, and a float plate 34 is connected to the outer side of the support rod 11. A slot 35 corresponding to the support rod 11 is provided on the side of the float plate 34. A retaining plate 36 is provided inside the slot 35 and is elastically connected to the side wall of the float plate 34. The retaining plate 36 and the slot 37 are engaged accordingly. An airbag 39 is installed on the bottom surface of the float plate 34, and an air pump 38 located on the side of the float plate 34 is connected to the outer side of the airbag 39.

[0034] In specific application scenarios, the float plate 34 is fixed at the bottom of the outer shell 1. The outer shell 1 and the float plate 34 are inserted into the support rod 11 through the fixing groove 10 and slot 35 respectively provided on their sides. The bottom end of the support rod 11 is fixed to the working surface before use. The float plate 34 is engaged with the slot 37 opened on the bottom inner side of the support rod 11 through the side-fixed clamping plate 36 to limit the position. When flooding occurs, the airbag 39 causes the whole to float under the action of water buoyancy. When there is little water, the buoyancy is insufficient, causing the float plate 34 to float and disengage from the slot 37. This can prevent a small amount of water from affecting the overall stability. The airbag 39 can be inflated by the air pump 38 to enhance its buoyancy and ensure its use in water-rich environments under water conservancy and hydropower.

[0035] The above technical solution facilitates the addition and use of the float 34, enables the use of buoyancy to cope with flood and waterlogged environments, and ensures electrical safety.
