Description

Technical Field

[0001] This utility model relates to the field of subway power supply safety technology, specifically a protective insulating ground structure for subway DC traction power supply equipment. Background Technology

[0002] The purpose of DC traction in subways is to provide power to subway trains. It converts alternating current (AC) from the power grid into direct current (DC), which drives the train through traction motors. This method allows for precise control of train speed and traction, enabling smooth acceleration, deceleration, and stopping. It also boasts advantages such as high efficiency, good speed regulation performance, and strong reliability. It can adapt to the frequent starts and stops and rapid operation requirements of subways in complex urban environments, ensuring the safe and efficient operation of the subway system.

[0003] The existing Chinese utility model patent with publication number CN213539596U discloses a construction structure for an insulating floor for a subway DC traction power supply equipment. This structure includes a cofferdam surrounding the power supply equipment to form a construction area, and an insulating layer poured onto the ground surface within the construction area. Grooves are formed on the ground surface of the construction area, and a waterproof layer is applied between the insulating layer and the ground surface. Embedded parts are placed within the grooves. A gap is left between the grooves and the embedded parts for pouring the insulating layer. The upper surface of the insulating layer is flush with the upper surface of the embedded parts. Multiple reinforcing plates are connected to the bottom of the embedded parts, perpendicular to the sides of the embedded parts and extending outwards. In this utility model, the insulating layer uses cast-in-place quartz sand and epoxy resin, resulting in superior insulation compared to traditional insulating boards. The multiple reinforcing plates at the bottom of the embedded parts improve their pull-out resistance and enhance overall structural stability. A positioning device is provided to adjust the level of the entire embedded part, ensuring that its upper surface is flush with the upper surface of the insulating layer.

[0004] Currently, the protective insulation floor structure of the DC traction power supply equipment used in subways still has the following problems:

[0005] Over time, insulated flooring will wear down, and the effects of external humidity will cause its moisture-proof performance to deteriorate, affecting its electrical resistance. Furthermore, the construction of insulated flooring is complex, and once it breaks, not only is repair difficult, but it also affects the normal use of equipment. Utility Model Content

[0006] The purpose of this utility model is to provide a protective insulating ground structure for subway DC traction power supply equipment to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] This utility model provides a protective insulating floor structure for subway DC traction power supply equipment, including an insulating floor surface. The surface of the insulating floor surface is coated with epoxy resin, and a bakelite insulating board is provided at the bottom of the insulating floor surface. A moisture-proof board and a water-passing board are arranged in sequence below the bakelite insulating board. The water-passing board is located below the moisture-proof board, and a frame board is installed at the bottom of the water-passing board. An installation vertical plate is fixedly installed inside the frame board, and a conical nail is connected to the bottom of the installation vertical plate.

[0009] The bakelite insulation board includes a wear-resistant layer below the surface, a high-temperature resistant layer below the wear-resistant layer, and a heat insulation layer installed at the bottom of the high-temperature resistant layer.

[0010] Preferably, the moisture-proof board includes:

[0011] A water guide plate is equidistantly connected to the bottom of a moisture-proof board, and a first waterproof layer is installed on the top inner layer of the moisture-proof board, with moisture-proof particles provided at the lower end of the first waterproof layer.

[0012] A bottom waterproof layer is located at the bottom of the moisture-proof particles and at the inner bottom of the moisture-proof board.

[0013] Preferably, a base plate is installed below the water-passing plate, and leakage detection rods for leakage detection are fixedly installed at both ends of the surface of the insulating floor.

[0014] Preferably, the water-passing plate and the frame plate are the same size, and a clamping plate is fixedly installed above the conical nail, and the clamping plate is fixedly connected to the bottom of the mounting plate. The conical nails are arranged in groups of three, and there are several groups of conical nails.

[0015] Preferably, the wear-resistant layer contains dispersed alumina particles, the heat insulation layer contains ceramic fiber cotton, and the high-temperature resistant layer is made of polytetrafluoroethylene.

[0016] Preferably, both sides of the first waterproof layer and the bottom waterproof layer are coated with polyurethane coating, and the water guide plates are equidistantly located at the upper end of the water-passing plate.

[0017] Preferably, the surface of the base plate is covered with a layer of crushed bluestone, and the card plate is located on top of the base plate.

[0018] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0019] 1. When used in insulating flooring, the water-passing plate is supported and fixed at the bottom by installing vertical plates and conical nails. This not only provides space for water flow at the bottom of the water-passing plate, but also increases the stability of the bottom of the water-passing plate. In addition, a moisture-proof plate is installed on top of the water-passing plate. The moisture-proof plate blocks the moisture below through a waterproof layer and moisture-proof particles, reducing the possibility of moisture seeping into the top. This design provides moisture protection and isolation below the insulating flooring, which can effectively prevent moisture from entering the insulation layer and improve the safety of the equipment during use.

[0020] 2. When used in insulating flooring, the bottom of the bakelite insulation board is equipped with a high-temperature resistant layer and a heat insulation layer. The high-temperature resistant layer can ensure that the insulation board maintains good insulation properties during high-temperature use. The heat insulation layer isolates the heat above the insulation board, preventing moisture below the moisture-proof board from affecting the normal electrical resistance of the equipment. In addition, the heat insulation layer can also prevent the equipment below the moisture-proof board from rusting and corroding, extending the service life of the equipment and reducing the possibility of equipment repair.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] Please see Figures 1-4 A protective insulating floor structure for subway DC traction power supply equipment includes an insulating floor surface 1, the surface of which is coated with epoxy resin, and a bakelite insulating board 2 is provided at the bottom of the insulating floor surface 1. The bakelite insulating board 2 includes a wear-resistant layer 21 below the surface, a high-temperature resistant layer 22 is provided below the wear-resistant layer 21, and a heat insulation layer 23 is installed at the bottom of the high-temperature resistant layer 22.

[0031] In this embodiment, the wear-resistant layer 21 contains dispersed alumina particles, the heat insulation layer 23 contains ceramic fiber cotton, and the high-temperature resistant layer 22 is made of polytetrafluoroethylene.

[0032] The protective insulating floor structure of the subway DC traction power supply equipment in this utility model uses bakelite insulating board 2, which is made of alumina particles dispersed in epoxy resin and formed by a thick coating process to form a wear-resistant layer 21, which thickens the surface of the insulating floor 1, improves the wear resistance of the insulating floor 1, makes the floor surface less prone to wear, and increases the insulation effect of the equipment. The high-temperature resistant layer 22 is made of polytetrafluoroethylene material, which makes its high-temperature resistance better. At the same time, the setting of ceramic fiber cotton heat insulation layer 23 can block heat between bakelite insulating board 2 and moisture-proof board 3, reducing the possibility that moisture under moisture-proof board 3 will affect the insulation effect of the equipment when heated.

[0033] Specifically, such as Figure 3As shown, a moisture-proof board 3 and a water-passing board 4 are sequentially arranged below the bakelite insulation board 2. The moisture-proof board 3 includes: a water-guiding plate 31, which is equidistantly connected to the bottom of the moisture-proof board 3, and a first waterproof layer 32 is installed on the top inner layer of the moisture-proof board 3, and moisture-proof particles 33 are provided at the lower end of the first waterproof layer 32; and a bottom waterproof layer 34, which is located at the bottom of the moisture-proof particles 33 and at the bottom inner end of the moisture-proof board 3.

[0034] In this embodiment, both sides of the first waterproof layer 32 and the bottom waterproof layer 34 are coated with polyurethane coating, and the water guide plate 31 is equidistantly located at the upper end of the water-passing plate 4.

[0035] The subway DC traction power supply equipment protective insulation floor structure of this utility model has a water guide plate 31 connected to the bottom of the moisture-proof plate 3, so that the water droplets formed by the moisture under the moisture-proof plate 3 flow downward through the water guide plate 31, reducing the possibility of moisture intrusion upward, and improving the moisture-proof effect to a certain extent. In addition, the moisture-proof plate 3 is also provided with a waterproof layer inside, which further blocks moisture and reduces the possibility of equipment leakage, rusting and corrosion.

[0036] Specifically, such as Figure 2 As shown, the water-passing plate 4 is located below the moisture-proof plate 3, and a frame plate 41 is installed at the bottom of the water-passing plate 4. An installation vertical plate 42 is fixedly installed inside the frame plate 41, and a conical nail 44 is connected to the bottom of the installation vertical plate 42.

[0037] In this embodiment, the water-passing plate 4 and the frame plate 41 are the same size, and a clamping plate 43 is fixedly installed above the conical nail 44. The clamping plate 43 is fixedly connected to the bottom of the mounting vertical plate 42. The conical nails 44 are arranged in groups of three, and there are several groups of conical nails 44.

[0038] The protective insulating floor structure of the subway DC traction power supply equipment in this utility model has a water-passing plate 4 installed and supported by a mounting vertical plate 42 and a conical nail 44. The conical nail 44 is inserted into the padding layer on the surface of the base plate 5, which increases the bottom stability of the water-passing plate 4. The mounting vertical plate 42 and the clamping plate 43 are designed to leave a gap between the water-passing plate 4 and the base plate 5, which facilitates the flow of water accumulated on the surface of the base plate 5. At the same time, the bottom of the conical nail 44 is stable and not easy to break, which can reduce the probability of later equipment maintenance.

[0039] Specifically, such as Figure 1 As shown, a base plate 5 is installed below the water-passing plate 4, and leakage detection rods 6 for leakage detection are fixedly installed at both ends of the surface of the insulating floor surface 1; the surface of the base plate 5 is covered with a layer of crushed stone, and the card plate 43 is located above the base plate 5.

[0040] The subway DC traction power supply equipment of this utility model protects the insulating floor structure. The bottom of the leakage current detection rod 6 is inserted into the interior of the insulating floor surface 1, which can detect leakage current in the floor surface in time, thereby increasing the safety of the equipment during use.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
