A multi-layer heat insulation device for vehicles in cold regions

Abstract

This utility model discloses a multi-layer thermal insulation device for vehicles operating in cold regions, relating to the field of thermal insulation technology. The device includes a water tank with a lid bolted to the top. An insulation installation structure is located on the water tank, comprising a first thermal insulation shell, two first rotating plates, two second rotating plates, and a second thermal insulation shell. The first and second thermal insulation shells are installed at their top and bottom with the rotating plates intersecting and secured by threaded bolts and inserts, forming a multi-directional fixing structure. This effectively resists vibrations such as track impacts and vehicle body swaying during train operation, preventing gaps between the insulation shell and the water tank surface. Simultaneously, the inlet and outlet pipes are fixed within the arc-shaped grooves of the arc-shaped plates using hoops, preventing the insulation material from hardening and shrinking in cold environments, thus ensuring the stability and sealing of the overall insulation structure and reducing heat loss.

Description

Technical Field

[0001] This utility model relates to the field of thermal insulation technology, and in particular to a multi-layer thermal insulation device for vehicles in cold regions. Background Technology

[0002] In high-altitude and cold regions (such as -20°C to -40°C), the water tank of a high-speed train is a key water supply component. It needs to continuously maintain the internal water temperature to prevent freezing and cracking, while also reducing heat loss to reduce energy consumption.

[0003] Existing insulation structures are mostly one-piece designs that match the shape of the water tank. During installation, the insulation sleeve needs to be completely inserted from the end of the water tank. However, the water tanks of high-speed trains are often arranged in close proximity to pipes, supports, and other components. The installation space for the one-piece insulation sleeve is limited, which not only results in low assembly efficiency, but also requires the entire insulation sleeve to be removed during subsequent water tank maintenance. After maintenance, it needs to be reinstalled and sealed, which is cumbersome and can easily lead to damage to the edges of the insulation sleeve, affecting the insulation effect. In addition, if the one-piece insulation sleeve shows signs of aging or damage, it needs to be replaced entirely, resulting in material waste and increased maintenance costs. Therefore, we propose a multi-layer insulation device for vehicles in cold regions. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a multi-layer heat insulation device for vehicles in cold weather. This device solves the problem that existing heat insulation structures are mostly one-piece molded designs that match the shape of the water tank. During installation, the heat insulation sleeve needs to be completely inserted from the end of the water tank. However, the water tank of a high-speed train is often arranged in close proximity to pipes, supports and other components, and the installation space of the one-piece heat insulation sleeve is limited. This not only results in low assembly efficiency, but also requires the entire heat insulation sleeve to be removed during subsequent water tank maintenance. After maintenance, it needs to be reinstalled and sealed, which is cumbersome and can easily lead to damage to the edge of the heat insulation sleeve, affecting the heat insulation effect. In addition, if the one-piece heat insulation sleeve is partially aged or damaged, it needs to be replaced entirely, resulting in material waste and increased maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer heat insulation device for vehicles operating in cold weather, comprising: The water tank has a cover bolted to the top. The thermal insulation installation structure is located on the water tank. The thermal insulation installation structure includes a thermal insulation shell, two rotating plates, two rotating plates, and a thermal insulation shell. The thermal insulation shells are fitted onto the outside of the water tank. Positioning seats are fixedly connected to the top and bottom of the thermal insulation shells. The two rotating plates are rotatably connected to the outer surface of the corresponding positioning seats. The two rotating plates are installed crosswise with the corresponding rotating plates at the top and bottom of the thermal insulation shell.

[0006] Preferably, the thermal insulation installation structure further includes four inserts and four locking bolts, with two rotating plates one and two rotating plates two slidably sleeved on the outer surface of the corresponding inserts, and the four locking bolts respectively connected to the internal threads of the corresponding inserts.

[0007] Preferably, a water inlet pipe is fixedly connected to one side of the water tank, and a drain pipe is fixedly connected to the side of the water tank away from the water inlet pipe.

[0008] Preferably, arc-shaped plates are fixedly connected to both sides of the first and second heat insulation shells, and arc-shaped grooves are opened on the outer surfaces of the four arc-shaped plates, with the water inlet pipe and the drain pipe located inside the corresponding two arc-shaped plates.

[0009] Preferably, the inlet pipe and the outlet pipe are respectively provided with ring clamps on the outside, and both ring clamps are bolted to the inside of the corresponding two arc-shaped grooves.

[0010] Preferably, a connecting strip is fixedly connected to the side of the heat insulation shell one near the heat insulation shell two, and a connecting groove is opened on the side of the heat insulation shell two near the heat insulation shell one, and the connecting strip slides and the connecting groove.

[0011] Preferably, the inlet pipe and the outlet pipe are respectively connected to the interior of the water tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This multi-layer thermal insulation device for high-altitude and cold-weather vehicles uses rotating plates 1 and 2 installed crosswise at the top and bottom of the thermal insulation shell 1 and thermal insulation shell 2, and is locked in place by the threaded locking of the inserts and locking bolts to form a multi-directional fixed structure. This structure can effectively resist the vibrations such as track impact and vehicle body shaking during the operation of the EMU, and avoid gaps between the thermal insulation shell and the surface of the water tank. At the same time, the water inlet pipe and the water outlet pipe are fixed in the arc groove of the arc plate by ring clamps to prevent the thermal insulation material from hardening and shrinking in the cold environment, which would cause the insulation at the pipe to loosen. This ensures the stability and sealing of the overall thermal insulation structure and reduces the heat loss rate. Attached Figure Description
