Description

Technical Field

[0001] The utility model relates to a generator, in particular to a generator with a limiting structure. Background Art

[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. As a power supply device, generators are widely used in various industries. During the use of the generator, the power components will generate certain vibrations, which will cause the power components to shift. When the power components shift, it will affect the stable connection with other components, thereby affecting the normal use of the generator.

[0003] Therefore, Chinese patent document CN108390490A discloses a generator offset limiting structure and a generator, which relates to the technical field of generators. The generator offset limiting structure includes a frame body, a power generation device, a first limiting assembly and a second limiting assembly. The first limiting assembly includes a limiting lug and a limiting rod with a first buffer at the end, the limiting lug is fixedly arranged on the frame body, and a first gap is provided between the first buffer and the limiting lug. The second limiting assembly includes a second buffer, the second buffer is detachably connected to the frame body, and a second gap is provided between the bottom support plate of the power generation device and the second buffer. The first limiting assembly and the second limiting assembly are used to limit the offset of the power generation device relative to the frame body. It has a reasonable design and a simple structure. Through the joint action of the first limiting assembly and the second limiting assembly, the offset of the power generation device in all directions is better limited, so as to achieve the purpose of buffering and shock absorption. In the prior art, the offset of the power generation device relative to the frame is limited by setting the first limiting assembly and the second limiting assembly, but the structure is complicated, the equipment cost is increased, and the assembly efficiency of the equipment is also reduced. Utility Model Content

[0004] In order to solve the technical problem of complex limiting structures of power generation equipment in the prior art, the utility model provides a generator with a limiting structure, comprising a base plate and an engine, wherein the engine is located on the base plate; wherein: a limiting structure is also included for limiting the displacement of the engine on the base plate, and two ends of the limiting structure are respectively located at the center of the engine and the base plate.

[0005] Compared with the prior art, in this solution, a limiting structure arranged at the center of the engine and the base plate is used to limit the displacement of the engine to prevent the engine from shifting relative to the base. Compared with the conventional solution in which the limiting structure is arranged in multiple directions around, the number of limiting structures can be reduced and the cost of the limiting structures can be reduced.

[0006] Preferably, the limiting structure includes a support ear and a limiting component with a notch, the support ear is located at the center of the bottom plate or the center of the bottom surface of the engine, the limiting component is located at the center of the bottom surface of the engine or the center of the bottom plate, and the support ear matches the limiting component. In this solution, the support ear can be limited by the cooperation of the support ear and the notch on the limiting component, thereby achieving the limitation of the engine on the bottom plate, which has a simple structure, can reduce the cost of the generator, and can also simplify the assembly steps of the generator and improve the assembly efficiency of the generator.

[0007] Preferably, the limiting structure further comprises a bracket mounted on the bottom plate, the engine is mounted on the bracket, the lug is located at the center of the bottom plate or the center of the bracket, and the limiting assembly is located at the center of the bracket or the center of the bottom plate. Compared with the method of directly setting the lug or the limiting assembly on the engine and modifying the bottom surface of the engine, this solution can avoid additional modification of the engine, thereby ensuring that the manufacturing cost of the engine is reduced.

[0008] Preferably, the limiting assembly includes a limiting plate corresponding to the support ear, the limiting plate encloses a notch, and the notch can wrap the support ear. In this solution, the limiting operation of the support ear is achieved by wrapping the support ear with the notch, and the structure is simple.

[0009] Preferably, a shock absorber is provided at the contact portion between the limit plate and the support ear. In this solution, the provision of the shock absorber can reduce the impact caused by the support ear and the limit plate contacting each other during the limit operation, thereby reducing the damage to the limit plate and the support ear due to the impact, extending the service life of the limit plate and the support ear, and reducing the vibration amplitude of the engine, thereby increasing the service life of the engine.

[0010] Preferably, the shock absorbing member is a shock absorbing rubber strip detachably connected to the limit plate. Considering that the shock absorbing member will wear out after long-term use, the shock absorbing member needs to be replaced in time to ensure the shock absorbing effect. In this solution, the detachable connection method facilitates the replacement of the shock absorbing member.

[0011] Preferably, the shock-absorbing rubber strip is provided with an insertion interface matching the limit plate. This solution facilitates the quick connection of the shock-absorbing rubber strip and the limit plate, and has a simple structure.

[0024] The following is further described in detail through specific implementation methods:

[0028] The embodiment is basically as shown in the attached Figure 1-Figure 7 As shown: the generator with a limiting structure includes a base plate 1 and an engine 2, the engine 2 is located on the base plate 1, specifically, a bracket 4 is installed on the base plate 1, the engine 2 is installed on the bracket 4, and the base plate 1 is as shown in FIG. Figure 2 shown.

[0029] It also includes a limiting structure for limiting the displacement of the engine 2 on the bottom plate 1, and the two ends of the limiting structure are respectively located at the center of the engine 2 and the bottom plate 1. The limiting structure includes a support ear 5 and a limiting component with a notch.

[0030] The bracket 4 is provided with a support ear 5 bent toward the bottom plate 1, and the support ear 5 is bent at a right angle to the bracket 4. Figure 3 , Figure 4 and Figure 5 Specifically, the bracket 4 is provided with a rectangular opening, the ears 5 are arranged along the four sides of the rectangular opening, and the ears 5 are arranged on the lower surface of the bracket 4 .

[0031] A limiting component with a notch is provided on the bottom plate 1 at a position corresponding to the lug 5, and the lug 5 matches the limiting component. Specifically, a limiting component with a rectangular notch is provided on the bottom plate 1. The limiting component includes four limiting plates 3 corresponding to the four-sided lugs 5, and the four limiting plates 3 enclose a rectangular notch, and the notch can wrap the lug 5, that is, the lug 5 can be inserted into the notch.

[0032] In other embodiments, the positions of the support ear 5 and the limiting assembly are interchanged, that is, the support ear 5 is arranged on the base plate 1 , and the limiting assembly is arranged on the bracket 4 .

[0033] In other embodiments, the lug 5 can also be directly arranged on the bottom surface of the engine 2 , and the installation of the bracket 4 is omitted. In this embodiment, the engine 2 is directly installed on the bottom plate 1 .

[0034] The portion of the limit plate 3 in contact with the support ear 5 is provided with a shock absorbing member 6. Specifically, the upper portion of the limit plate 3 is provided with a shock absorbing member 6. In this embodiment, the shock absorbing member 6 is a shock absorbing rubber strip. The shock absorbing rubber strip is provided with a through insertion port 7 along the length direction.
