The heat and sound insulating casing of the diesel generator comprises a frame 1 and a guard made in the form of a fabric tent 2. Frame 1 includes arched racks 3, a base made in the form of a closed frame 4, and load-bearing connections 5. Arched racks 3 are mounted on the bottom 4 on the frame 4 and on top connected to the load-bearing bonds 5. The fabric tent 2 is fixed around the perimeter on the frame 4. The frame 4 of the casing and the base of the diesel generator can be fastened.

The fabric awning 2 in a specific example is made of silica fabric KT-11-C8 / 3-PU. This fabric is waterproof, resistant to high temperatures up to 1000 ° C and to chemical influences, environmentally friendly, harmless to human health, resistant to decomposition by microorganisms.

The fabric tent 2 is preferably made in two layers. The inner layer of fabric tent 2 can be made of sound and heat insulating material, for example, basalt fireproof material MBOR-10F. This material has high thermal insulation properties, has a high sound absorption coefficient, is environmentally friendly, non-combustible, has increased vibration resistance and resistance to high temperatures, up to 900 ° C. The outer layer of fabric awning 2 can be made of waterproof material, in particular of silica fabric KT-11 -C8 / 3-PU. Layers of fabric awning 2 stitched.

The fabric awning 2 has through holes along the contour 6, reinforced with grommets, which are adapted to be put on the swing brackets 7, mounted on the frame 4 by means of fixing brackets 8. The swing brackets 7 have axes of rotation 9. The mounting brackets 8 are fixed on the frame 4 by means of rivets 10. The fastening elements of the fabric tent 2 on the frame 4 are installed in the places of fastening of the arched posts 3 on the frame 4.

At the front end of the fabric tent 2, a window 11 is made for access to the control unit of the diesel generator. In the rear end of the tent 2, a ventilation window 12 is made for the cooling air to enter the diesel generator engine. In the fabric awning 2 on the right side, there is a ventilation window 13 for air to exit from the diesel generator engine and a ventilation window 14 for the diesel generator. In the fabric tent 2 on the left side, a window 15 is made for air to enter combustion. All windows can be closed by folding fabric valves.

Heat and sound insulating casing of a diesel generator is used as follows.

Before use, the frame 1 is mounted. The frame 4 of the frame 1 is fixed to the base of the diesel generator. The fabric tent 2 is put on the frame 1. In the holes 6 in the tent 2 the rotational brackets 7 of the fastening elements are inserted, as a result of which the tent 2 is fixed around the perimeter on the frame 4. The casing protects the diesel generator from external influences, climatic factors (snow, rain, dust dirt, cold, etc.) that adversely affect their condition during operation.

When the diesel generator is running, the heat generated from it is isolated from the external environment by a two-layer fabric material of the tent 2. From the casing, the generated heat is removed by directed flows through the ventilation windows 13, 14. Sound insulation of the working diesel generator is also carried out by the two-layer fabric material of the tent 2. Air inlet for combustion and cooling air into the engine, necessary for the operation of the diesel generator, are supplied to them by means of windows 15 and 12. Access to the control unit of the diesel generator is carried out through the window 11 in the front end of the fabric tent 2.

The claimed utility model provides an important technical result, consisting in increasing the manufacturability of the design of the heat and sound insulating casing of the diesel generator.

The execution of the casing containing the frame, made of a typical metal profile, technologically advanced and easily connected parts, which reduces the number of installation operations in the manufacture of the casing.

The execution of the fence in the form of a fabric tent allows to exclude the operation of fastening a large number of enclosing elements, which simplifies the assembly of the casing.

The manufacture of fencing in the form of a stitched fabric awning is performed according to a simple pattern, consisting of a direct panel, which is sewn with the same end parts, which increases the manufacturability of the awning in its manufacture. Making the windows necessary for servicing the diesel generator is not difficult, because these windows are cut out on flat panels before stitching the awning.

As a result of the casing being detachable, due to the non-rigid fastening of the guard to the frame, if necessary, it can be easily disassembled and repaired. In addition, the fabric awning is easily repaired by patching or stitching new seams, and the same type of frame elements are also easily replaced by serviceable ones, which increases the manufacturability of the casing maintenance.

The implementation of the fabric tent with a two-layer, sewn from layers of fabric, provides ease of manufacture of the tent and through holes in it for fixing on the frame.

Thus, the manufacturability of the heat and sound insulating casing of the diesel generator is significantly increased.

Prototypes of the casing are made and tested by LLC President-Neva Energy Center, St. Petersburg.
