Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of exhaust structures, and mainly relates to an exhaust structure with rain-proof and drainage functions. Background Art
[0002] Box-type power station diesel generator sets, land-based units, pump sets, etc. are used in the open air environment for a long time. The external environment is complex. There is a risk that rainwater and the like enter the exhaust pipe during long-term use, which will affect the performance of the diesel engine. Therefore, preventing rainwater and the like from entering the exhaust pipe has become the key to the protection design of the exhaust structure. To solve this problem, an exhaust structure that can automatically open and close with the start of the diesel engine and has the functions of rain-proof and water-discharge is designed. Summary of the Utility Model
[0003] To solve the above technical problems, the utility model proposes an exhaust structure with rain-proof and drainage functions, so that the exhaust port has the rain-proof function and can ensure use in rainy environments.
[0004] The utility model adopts the following technical solutions to complete its tasks:

[0006] The rain-proof cover is made of a thin steel plate, which can cover the exhaust pipe opening when the diesel engine is not running, playing a rain-proof role. When the diesel engine starts, affected by the exhaust impact of the diesel engine, the rain-proof cover opens and the exhaust is discharged.
[0007] The heat-resistant gasket is an inorganic fiber composite product, which has the characteristics of high temperature resistance, tensile resistance, unchanged geometric shape, non-breaking, non-peeling, non-clumping, non-dropping, non-dusting, and non-combustible materials. As an exhaust port gasket, it needs to withstand a higher temperature and avoid combustion due to high temperature.

[0009] 1. The exhaust pipe is installed with a rain shield, which can play a role in preventing rain and avoid the situation that the opening angle of the rain shield is too large and cannot be automatically restored.
[0010] 2. Adding a counterweight can freely adjust the opening pressure of the rain shield and avoid excessive exhaust pressure of the diesel engine.
[0011] 3. The drain cock can discharge the dirt during the use of the diesel engine to ensure the normal use of the exhaust pipe.
[0012] 4. The drain cock can discharge a small amount of rainwater that enters due to heavy rain to ensure the normal use of the diesel engine. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] As Figures 1 - 4 shown, an exhaust structure with rain-proof and drainage functions, the exhaust structure has an exhaust pipe 1 connected to the pipeline of the exhaust port of the diesel engine; the exhaust pipe 1 is arranged vertically; a rain shield 3 is arranged at the top opening of the exhaust pipe 1; the rain shield 3 is a structure that can be opened when the diesel engine starts; a heat-resistant gasket 4 serving as a rain shield gasket is connected to the inner wall surface of the rain shield; one end of the rain shield 3 is welded with a mounting block 5; the mounting block 5 is hinged to a bracket 2 welded on one side of the exhaust pipe; a counterweight screw 6 is fixed on the mounting block; the counterweight screw 6 and the rain shield 3 are arranged on both sides of the mounting block 5; a counterweight 7 is installed on the counterweight screw 6, and by adjusting the position of the counterweight 7 on the counterweight screw 6, the force required for opening and closing the rain shield can be adjusted to avoid the situation of excessive exhaust pressure of the diesel engine; a drain cock 8 for discharging the accumulated water in the exhaust pipe is installed at the lowest point of the exhaust pipe.
[0019] The exhaust pipe 1 is a pipe connecting to the exhaust port of the diesel engine, and discharges the exhaust gas of the diesel engine vertically upward through the exhaust pipe; the bracket 2 is fixed to the exhaust pipe by welding, and a fixing rod is installed in the middle of the bracket for the rotation of the rain cover; sufficient clearance should be reserved during the welding of the bracket to ensure that the rain cover 3 can rotate under the action of the exhaust gas of the diesel engine; the rain cover 3 is made of thin steel plate, which covers the exhaust pipe opening when the diesel engine is not started, and can play a rain-proof role. When the diesel engine starts, under the impact of the exhaust gas of the diesel engine, the rain cover 3 opens and the exhaust gas is discharged; the heat-resistant gasket 4 is made of inorganic fiber composite products, which has the properties of high temperature resistance, tensile resistance, unchanged geometric shape, no breakage, no peeling, no agglomeration, no falling, no dust generation, and non-combustible material. As a gasket for the exhaust port, it needs to withstand a relatively high temperature and avoid combustion due to high temperature. The heat-resistant gasket 4 is fixed to the rain cover 3 as a whole. During the opening and closing process of the rain cover 3, the heat-resistant gasket 4 contacts the exhaust pipe 1, and the gasket absorbs the impact force to avoid noise and damage to the rain cover due to impact; the mounting block 5 is welded to the rain cover, and a hole is opened in the middle of the mounting block 5 to cooperate with the fixing rod of the bracket 2. The mounting block needs to be designed to prevent the rain cover from opening too large an angle and avoid being unable to close automatically, as shown in Figure 3 .4; the counterweight screw 6 is fixed to the mounting block 5 as a whole and is used to install the counterweight block 7. A threaded hole is drilled in the middle of the counterweight block 7. After connecting the counterweight screw 6 and the counterweight block 7 as a whole, the force required for opening and closing the rain cover is adjusted by adjusting the position of the counterweight block 7 on the counterweight screw 6 to avoid the situation of excessive exhaust gas pressure of the diesel engine. The drain cock 8 is installed at the lowest point of the exhaust pipe 1. During the long-term use of the diesel engine, due to the presence of high-temperature water vapor in the exhaust gas and the condensation of the exhaust pipe when it is cooled, water will accumulate in the exhaust pipe, and the diesel engine cannot achieve complete combustion. Therefore, unburned ash will accumulate in the exhaust pipe over time. The drain cock can discharge the accumulated water / ash to keep the exhaust pipe in normal use. And if the diesel engine starts in heavy rain, there may be a situation where a small amount of rainwater enters the exhaust pipe, and the rainwater can be discharged through the drain cock.
