Description

Technical Field

[0001] This application relates to the technical field of gas generator sets, and particularly to an installation structure of a gas generator set for combined heat and power (CHP). Background Art

[0002] Combined heat and power (CHP) is an efficient energy utilization technology that generates both electrical energy and thermal energy simultaneously. Its core lies in achieving the output of two types of energy through a single energy input, thereby improving the overall efficiency. Among them, gas generator sets in CHP have both power generation and heat recovery functions, significantly improving energy efficiency, reducing emissions, and possessing flexibility and economy, which are the core components of the CHP system.

[0003] Currently, gas generator sets in combined heat and power are usually fixedly installed on I-beam supports, and the I-beam supports are fixedly connected to the ground through multiple bolts, making the installation structure of the gas generator set closely related to the working efficiency of the gas generator set during the combined heat and power process.

[0004] However, the gas generator set will generate vibrations during operation, which cause relatively large damage to the I-beam support. After the connection of the I-beam support becomes loose due to vibration, it will cause the gas generator set to vibrate to a greater extent during operation, not only affecting the efficiency of combined heat and power, but also easily leading to faults and damages of the gas generator set, and even potentially posing relatively large safety hazards. Summary of the Invention

[0005] This application provides an installation structure of a gas generator set for combined heat and power (CHP), which can effectively reduce the vibrations generated by the gas generator set during operation, thereby effectively improving the working stability of the gas generator set.

[0006] This application provides an installation structure of a gas generator set for combined heat and power (CHP), adopting the following technical solutions:

[0007] An installation structure of a gas generator set for combined heat and power (CHP) includes a support device and a vibration damping device;

[0008] The support device includes a frame body, a support member, and a limiting member; the frame body is vertically installed on the ground, and an installation space for installing the gas generator set is horizontally penetrated through the middle position of the frame body; both the support member and the limiting member are vertically movably connected to the frame body and are both located in the installation space, the support member is located below the limiting member, and the gas generator set is installed between the support member and the limiting member;

[0009] The vibration damping device includes a first vibration damping component, a second vibration damping component, and a linkage component;

[0010] The first damping component is installed at the bottom of the installation space and below the support member. The first damping component includes a plurality of first fixing members, a plurality of first moving members, and a plurality of first elastic members that correspond one by one. The first fixing members are fixedly connected to the frame body. The first moving members are movably connected to the first fixing members in the vertical direction and are connected to the support member. Two ends of the first elastic member are respectively connected to the first fixing member and the first moving member, and have a tendency to drive the first moving member to move upward.

[0011] The second damping component is installed at the top of the installation space and above the limiting member. The second damping component includes a plurality of second fixing members, a plurality of second moving members, and a plurality of second elastic members that correspond one by one. The second fixing members are fixedly connected to the frame body. The second moving members are movably connected to the second fixing members in the vertical direction and are connected to the limiting member. Two ends of the second elastic member are respectively connected to the second fixing member and the second moving member, and have a tendency to drive the second moving member to move downward.

[0012] The linkage component includes a rotating member. A cavity is formed inside the frame body. One end of the cavity communicates with the internal spaces of the plurality of first fixing members and is respectively sealed by the plurality of first moving members. The other end of the cavity communicates with the internal spaces of the plurality of second fixing members and is respectively sealed by the plurality of second moving members. The rotating member is rotatably connected to the frame body and is located in the cavity. The rotating member divides the cavity into two sealed spaces and two rotating spaces, and the rotating member rotates in the rotating space. The two sealed spaces and the two rotating spaces correspond one by one. During the rotation of the rotating member, the size change conditions of the two sealed spaces are the same, and the size change condition of the sealed space is opposite to that of the corresponding rotating space.

[0013] By adopting the above technical solution, when the gas generator set vibrates during operation, the first damping component and the second damping component will be triggered, driving the first moving member and the second moving member to move relative to each other. During this process, the first elastic member and the second elastic member will absorb part of the vibration. Then, during the movement of the first moving member or the second moving member, both can drive the second moving member or the first moving member to move in the opposite direction through the linkage component, so as to effectively suppress the vibration of the gas engine, and further effectively reduce the vibration degree during the operation of the gas generator set, so as to effectively improve the working stability of the gas generator set.

[0014] Optionally, the first damping component includes a first synchronization plate, and the second damping component includes a second synchronization plate.

[0015] A plurality of the first movable members are fixedly connected to the first synchronizing plate, and the first synchronizing plate is fixedly connected to the gas generator set; a plurality of the second movable members are fixedly connected to the second synchronizing plate, and the second synchronizing plate is fixedly connected to the gas generator set.

[0016] By adopting the above technical solution, the vibration damping effects of the first vibration damping component and the second vibration damping component on the gas generator set can be made more uniform, so that the gas generator set can still maintain a horizontal state as much as possible during the vibration process, ensuring the effects and efficiency of the gas generator set. At the same time, the probability of the gas generator set being damaged due to low installation levelness can be effectively reduced, and thus the working stability and safety of the gas generator set can be improved.

[0017] Optionally, the linkage assembly further includes a third elastic member;

[0018] Two ends of the third elastic member are respectively connected to the rotating member and the frame body, and have a tendency to drive the rotating member to rotate until the sizes of the two sealing spaces are equal and remain so.

[0019] By adopting the above technical solution, during the process of the rotating member rotating with the vibration of the gas generator set, the third elastic member can also absorb part of the vibration, thereby effectively improving the effect of the vibration damping device in suppressing the vibration of the gas generator set through the linkage assembly.

[0020] Optionally, the linkage assembly further includes two air nozzles for controlling the gas to enter and exit the cavity. The two air nozzles correspond to the two sealing spaces one by one, and the air nozzles communicate with the corresponding sealing spaces.

[0021] By adopting the above technical solution, it is convenient for the staff to control the positions of the support member and the limiting member in the installation space according to the needs, so as to facilitate the installation of the gas generator set in the installation space; at the same time, it is convenient for the staff to control the air pressure in the two sealing spaces according to the needs, so as to adjust the vibration damping effects of the first vibration damping component and the second vibration damping component on the gas generator set.

[0022] Optionally, it further includes a leveling device;

[0023] The leveling device includes a leveling member. An installation groove adapted to the bottom of the gas generator set is formed at the top of the support member, and the leveling member is detachably connected to the support member; after the gas generator set is installed on the support member, the bottom of the gas generator set is clamped and positioned between the leveling member and the support member.

[0024] By adopting the above technical solution, it is possible to facilitate the installation of the gas generator set in a horizontal position state in the installation space, thereby effectively improving the levelness of the gas generator set after installation, and further effectively reducing the harm caused by vibration of the gas generator set in a state with low installation levelness.

[0025] Optionally, the leveling device includes a plurality of elastic pads;

[0026] The elastic pads are arranged in the installation grooves. After the gas generator set is installed on the support member, the bottom of the gas generator set is clamped and positioned between the leveling member and the elastic pads.

[0027] By adopting the above technical solution, it is possible to facilitate the installation of the gas generator set by the staff in the installation space with the leveling member as an aid, so that the gas generator set has sufficient levelness after installation; at the same time, when the gas generator set vibrates during operation, the elastic pads can also play a role in absorbing vibration, thereby being able to further reduce the impact caused by the vibration of the gas generator set.

[0028] Optionally, the leveling device includes at least two spirit levels, and the spirit levels are horizontally arranged on the leveling member, and the setting directions of at least two of the spirit levels are perpendicular to each other.

[0029] By adopting the above technical solution, it is possible to facilitate the horizontal installation of the gas generator set with the help of the spirit levels, effectively ensuring the levelness of the gas generator set after installation; at the same time, it is possible to facilitate the staff to observe the spirit levels during the operation of the gas generator set to judge the levelness of the installation position of the gas generator set at this time, and stop the machine for maintenance in time when the levelness of the gas generator set is insufficient, thereby being able to further improve the stability and safety of the gas generator set when it is put into use.

[0030] Optionally, the leveling device altogether includes four spirit levels; the four spirit levels are respectively located around the leveling member, and the setting directions of the two spirit levels on both sides of the leveling member are parallel to each other;

[0031] Observation ports are provided on both sides of the frame body, and the observation ports communicate with the installation space.

[0032] By adopting the above technical solution, it is possible to further improve the reliability of the staff to judge the levelness of the installation of the gas generator set by observing the spirit levels, and at the same time it is possible to further facilitate the staff to know the levelness of its installation by observing the spirit levels during the installation process and the operation process of the gas generator set.

[0033] Optionally, the leveling device further includes a blowing assembly, and the blowing assembly is arranged on the support member;

[0034] The air blowing assembly includes a blower and a one-way air valve; the blower continuously blows air into the installation groove through the one-way air valve, and the elastic pad forms a seal above the air inlet position in the installation groove.

[0035] By adopting the above technical solution, when the elastic pad causes a low levelness of the installation of the gas generator set due to vibration wear, the air blowing assembly can blow in gas, driving the elastic pad to apply a force to the gas generator set below it, so that the bottom of the gas generator set remains in contact with and abuts against the leveling member, thereby enabling the gas generator set to maintain a sufficient levelness while working for a long time.

[0036] Optionally, the leveling device includes a total of two elastic pads. The elastic pad at the bottom has a sealed air cavity inside, and the blower communicates with the air cavity.

[0037] By adopting the above technical solution, it can effectively improve the reliability and stability of the air blowing assembly to blow air so that the bottom of the gas generator set remains in contact with and abuts against the leveling member, and at the same time can effectively reduce the probability of the air blowing assembly failing due to gas leakage.

[0038] In summary, the present application includes at least one of the following beneficial effects:

[0039] 1. It can effectively reduce the vibration generated by the gas generator set during operation, thereby effectively improving the stability of the gas generator set during operation.

[0040] 2. It can effectively improve the levelness of the installation of the gas generator set, facilitating the installation of the gas generator set by the staff, and at the same time can effectively improve the working effect and efficiency of the subsequent gas generator set.

[0041] 3. It can keep a certain levelness during the operation and vibration of the gas generator set, reducing the probability of the gas generator set being affected by vibration under the condition of low levelness.

[0042] 4. When the levelness of the gas generator set is low due to vibration during the operation and vibration of the gas generator set, it can automatically adjust the levelness of the gas generator set to restore a certain levelness, thereby effectively ensuring the stability and safety of the operation of the gas generator set.

Detailed implementation manners

[0050] The following further elaborates on the present application in conjunction with the attached Figures 1-6 drawings.

[0051] Referring to Figure 1 and Figure 2 , an embodiment of the present application discloses an installation structure of a gas-fired generator set for combined heat and power (CHP), which facilitates the installation and fixation of the gas-fired generator set 2 on the ground 1, can effectively reduce the vibration generated during the operation of the gas-fired generator set 2, and can effectively ensure the levelness of the installation position of the gas-fired generator set 2 during the operation process, thereby effectively ensuring the efficiency and effect of the operation of the gas-fired generator set 2, and effectively improving the stability and safety of the operation of the gas-fired generator set 2. In this embodiment, it is preferred that the gas-fired generator set 2 has a structure with a housing, and its overall shape is a cuboid structure; since it is a prior art in the field that the gas-fired generator set for combined heat and power is equipped with a housing, it will not be elaborated herein, and it is only briefly shown in the drawings.

[0052] Referring to Figure 1 and Figure 3The installation structure includes a support device 3, a vibration reduction device 4 and a leveling device 5. The support device 3 is used to mainly support the gas generator set 2, so as to facilitate the fixed installation of the gas generator set 2 on the ground 1; the vibration reduction device 4 is used to reduce the vibration of the gas generator set 2, and can reduce the vibration generated by the gas generator set 2 during its operation; the leveling device 5 is used to facilitate the staff to confirm the horizontality of the gas generator set 2 during the installation and operation process, and can also keep the gas generator set 2 sufficiently horizontal during the operation process to ensure the stability and safety of the gas generator set 2.

[0053] The supporting device 3 includes a frame 31 , a supporting member 32 and a limiting member 33 .

[0054] The frame 31 is a rectangular parallelepiped structure as a whole, and an installation space 311 for installing the gas generator set 2 is provided inside the frame along its length direction, and the frame 31 is fixedly installed on the ground 1; after the gas generator set 2 is installed in the installation space 311, the length direction of the gas generator set 2 is parallel to the length direction of the frame 31, and its width direction is also parallel to the width direction of the frame 31. In this embodiment, the bottom of the frame 31 preferably has a boss extending outward in the horizontal direction, and a plurality of through holes for bolts to pass through are provided on the boss, so that the frame 31 can be fixedly installed on the ground 1 by a plurality of bolts and threaded sleeves pre-buried and installed underground; and the levelness of the ground 1 on which the frame 31 is installed preferably meets the requirements for stable operation of the gas generator set 2.

[0055] The support member 32 and the limit member 33 are both rectangular plate-shaped structures as a whole, and are both installed in the installation space 311; the support member 32 is located at the bottom of the installation space 311, and is movably connected to the frame 31 along the height direction of the frame 31, and its length direction is parallel to the length direction of the frame 31, and its movable direction is parallel to its own thickness direction; the limit member 33 is located at the top of the installation space 311, and is movably connected to the frame 31 along the height direction of the frame 31, and its length direction is parallel to the length direction of the frame 31, and its movable direction is parallel to its own thickness direction.

[0056] The gas generator set 2 is installed between the support member 32 and the limiting member 33 in the installation space 311. The bottom of the gas generator set 2 is fixedly connected to the support member 32, and the top of the gas generator set 2 is fixedly connected to the limiting member 33. During the operation of the gas generator set 2, vibration will cause it to have a tendency to undergo a small displacement. At this time, due to the restriction of the movable connection between the support member 32 and the limiting member 33 and the frame body 31, the gas generator set 2 can only have a tendency to undergo a small displacement along the height direction of the frame body 31. In this embodiment, preferably, after the support device 3 is installed on the ground 1, the support member 32 and the limiting member 33 are aligned in the vertical direction. And preferably, when the gas generator set 2 vibrates during operation and has a tendency to undergo a small displacement, it can drive the support member 32 and the limiting member 33 to have the same tendency to undergo a small displacement in the same direction.

[0057] Referring to Figure 3 and Figure 4 , the vibration damping device 4 includes a first vibration damping component 41 and a second vibration damping component 42. The first vibration damping component 41 and the second vibration damping component 42 are respectively located at the bottom and top of the installation space 311, and are respectively used to damp the support member 32 and the limiting member 33.

[0058] Referring to Figure 3 and Figure 5 , the first vibration damping component 41 includes a plurality of first fixing members 411, a plurality of first movable members 412 and a plurality of first elastic members 413 that correspond one by one.

[0059] The first fixing members 411 are fixedly installed at the bottom of the frame body 31 and are located at the bottom of the installation space 311, and the plurality of first fixing members 411 are uniformly distributed in a rectangular array on the inner wall of the bottom of the installation space 311. The inside of the first fixing member 411 is designed to be hollow. One end of the first movable member 412 is in penetration fit with the first fixing member 411 and is movably connected to the first fixing member 411 along the direction parallel to the height direction of the frame body 31. The other end of the first movable member 412 remains on the side of the corresponding first fixing member 411 close to the center position of the installation space 311 during the process of the first movable member 412 moving relative to the corresponding first fixing member 411, and a fixed connection is formed between it and the support member 32. The first elastic member 413 is installed inside the corresponding first fixing member 411, and its two ends are respectively fixedly connected to the corresponding first fixing member 411 and the corresponding first movable member 412, and it has a tendency to drive the corresponding first movable member 412 to move relative to the corresponding first fixing member 411 towards the center of the installation space 311 to the limit position and stay. In this embodiment, preferably, the first elastic member 413 is a spring, and after the gas generator set 2 is installed, the plurality of first elastic members 413 will all be in a compressed state.

[0060] The second damping assembly 42 includes a plurality of second fixing members 421, a plurality of second movable members 422, and a plurality of second elastic members 423 that correspond one by one.

[0061] The second fixing members 421 are fixedly installed on the top of the frame body 31 and located at the top of the installation space 311, and the plurality of second fixing members 421 are evenly distributed in a rectangular array on the inner wall of the top of the installation space 311; the inside of the second fixing members 421 is designed to be hollow, one end of the second movable member 422 is in penetration fit with the second fixing member 421 and is movably connected to the second fixing member 421 in a direction parallel to the height direction of the frame body 31, and the other end of the second movable member 422 remains on the side of the corresponding second fixing member 421 close to the center position of the installation space 311 during the process of the second movable member 422 moving relative to the corresponding second fixing member 421, and a fixed connection is formed between it and the limiting member 33; the second elastic member 423 is installed inside the corresponding second fixing member 421, and its two ends are respectively fixedly connected to the corresponding second fixing member 421 and the corresponding second movable member 422, and it has a tendency to drive the corresponding second movable member 422 to move relative to the corresponding second fixing member 421 towards the center of the installation space 311 to the limit position and stay. In this embodiment, it is preferred that the second elastic member 423 is a spring, and after the gas generator set 2 is installed, the plurality of second elastic members 423 will all be in a compressed state; and it is preferred that the plurality of second fixing members 421 and the plurality of second movable members 422 of the second damping assembly 42 respectively correspond one by one to the plurality of first fixing members 411 and the plurality of second movable members 422 of the first damping assembly 41 along the height direction of the frame body 31.

[0062] At this time, when the gas generator set 2 is installed in the installation space 311 and vibrates during operation, the plurality of first elastic members 413 and the plurality of second elastic members 423 in the compressed state can both absorb part of the vibration of the gas generator set 2, so as to effectively reduce the vibration generated when the gas generator set 2 is working.

[0063] Further, to ensure the levelness of the installation position of the gas generator set 2 during operation and vibration, and reduce the influence of vibration on the levelness of its installation position, it is preferred that the first damping assembly 41 further includes a first synchronization plate 414, and it is preferred that the second damping assembly 42 further includes a second synchronization plate 424.

[0064] The first synchronization plate 414 is integrally in a rectangular plate-like structure. One ends of multiple first movable members 412, which are away from the corresponding first fixed members 411, are fixedly connected to the first synchronization plate 414, and the first synchronization plate 414 is also fixedly connected to the support member 32, so that the multiple first movable members 412 are fixedly connected to the support member 32 through the first synchronization plate 414. In this embodiment, preferably, the rectangular dimensions of the first synchronization plate 414 and the support member 32 are equal; and preferably, the first synchronization plate 414 and the support member 32 are fixedly connected by a plurality of bolts; since the fixed connection by bolts is a common prior art, it will not be elaborated herein, and the bolts and related structures are omitted in the drawings.

[0065] The second synchronization plate 424 is integrally in a rectangular plate-like structure. One ends of multiple second movable members 422, which are away from the corresponding second fixed members 421, are fixedly connected to the second synchronization plate 424, and the second synchronization plate 424 is also fixedly connected to the limiting member 33, so that the multiple second movable members 422 are fixedly connected to the limiting member 33 through the second synchronization plate 424. In this embodiment, preferably, the rectangular dimensions of the second synchronization plate 424 and the limiting member 33 are equal; and preferably, the second synchronization plate 424 and the limiting member 33 are fixedly connected by a plurality of bolts; since the fixed connection by bolts is a common prior art, it will not be elaborated herein, and the bolts and related structures are omitted in the drawings.

[0066] At this time, when the gas generator set 2 is installed in the installation space 311 and vibrates during operation, the multiple first elastic members 413 and the multiple second elastic members 423 in the compressed state can respectively play a uniform vibration damping effect on the gas generator set 2 under the action of the first synchronization plate 414 and the second synchronization plate 424, and at the same time can make the gas generator set 2 vibrate more evenly during the vibration during operation, so as to ensure that it maintains a high levelness during operation.

[0067] Refer to Figure 2 and Figure 6 Furthermore, in order to further improve the vibration damping effect of the vibration damping device 4 on the gas generator set 2 during operation, preferably, the vibration damping device 4 further includes a linkage assembly 43.

[0068] The linkage assembly 43 includes a rotating member 431, a third elastic member 432 and two air nozzles 433.

[0069] Refer to Figure 3 and Figure 5, a cavity 312 is formed inside the structure of the frame body 31, and the cavity 312 is distributed at the top of the frame body 31, one side in the width direction of the frame body 31, and the bottom of the frame body 31; one end of the bottom of the cavity 312 communicates with the internal spaces of a plurality of first fixing members 411 at the same time and is sealed by a plurality of first moving members 412 at the same time; one end of the top of the cavity 312 communicates with the internal spaces of a plurality of second fixing members 421 at the same time and is sealed by a plurality of second moving members 422 at the same time.

[0070] Refer to Figure 2 and Figure 6 , the rotating member 431 is rotatably installed inside one side in the width direction of the frame body 31 and is located in the cavity 312, its rotation axis is parallel to the width direction of the frame body 31, and during its rotation, it keeps separating the cavity 312 to form two corresponding sealed spaces 3121 and two rotating spaces 3122.

[0071] The position of the sealed space 3121 close to the rotating member 431 is adjacent to the corresponding rotating space 3122 and is separated by one end in the length direction of the rotating member 431; the position of the sealed space 3121 close to the rotating member 431 is also adjacent to the other rotating space 3122 and is separated by the whole of the rotating member 431.

[0072] During the rotation of the rotating member 431 in the cavity 312, it is limited by the size of the rotating space 3122, and during the rotation of the rotating member 431, the sizes of both the sealed space 3121 and the rotating space 3122 change; when the rotating member 431 rotates to the position where the volume of the rotating space 3122 is the largest, at this time, the rotating member 431 is in a horizontal position state in the length direction, and at this time, the volume of the sealed space 3121 is the smallest. During the relative rotation of the rotating member 431 with respect to the frame body 31, the change trends of the volumes of the two sealed spaces 3121 are the same and the change amounts are the same, and the change trends of the volumes of the two rotating spaces 3122 are the same and the change amounts are also the same.

[0073] Both ends of the third elastic member 432 are fixedly connected to the rotating member 431 and the frame body 31 respectively, and it has a tendency to drive the rotating member 431 to rotate to the position state where the volume of the rotating space 3122 is the largest and maintain it. In this embodiment, it is preferred that the third elastic member 432 is a torsion spring; since the torsion spring is a common prior art, it will not be elaborated here, and only the installation position of the third elastic member 432 is shown in the drawings and its structure is omitted from the expression.

[0074] Refer to Figure 5 and Figure 6, after the gas generator set 2 is installed in the installation space 311, the rotating member 431 will maintain its position state with the length direction horizontal under the action of the third elastic member 432; at this time, when the gas generator set 2 vibrates during operation, during the process that the gas generator set 2 has a small displacement relative to the frame 31 in the height direction of the frame 31, the volumes of the two sealed spaces 3121 will both change and the change trends are opposite, and when the volume of one sealed space 3121 changes, it will drive the rotating member 431 to rotate relative to the frame 31 and drive the volume of the other sealed space 3121 to change in the same trend; since the trend that one sealed space 3121 drives the volume of the other sealed space 3121 to change as the gas generator set 2 vibrates and displaces and the trend that the rotating member 431 rotates as the gas generator set 2 vibrates and displaces to drive the volume of the other sealed space 3121 to change are opposite, the linkage assembly 43 can effectively suppress the situation that the gas generator set 2 vibrates and displaces.

[0075] Referring to Figure 2 and Figure 6 , a part of the rotating member 431 is exposed on one side in the width direction of the frame 31, and during the rotation of the rotating member 431, its sealing effect on the cavity 312 can be maintained; the two nozzles 433 are both fixedly installed on the rotating member 431, the two nozzles 433 communicate with the two sealed spaces 3121 respectively, and the nozzles 433 are used to control the gas to enter and exit the corresponding sealed spaces 3121; one end of the nozzle 433 communicates with the corresponding sealed space 3121, and the other end of the nozzle 433 is located on one side of the exposed position of the rotating member 431, which is convenient for the staff to control the gas to enter and exit the sealed space 3121. In this embodiment, preferably, the nozzle 433 can change the communication state between the sealed space 3121 and the outside according to requirements; since the nozzle 433 with the above functions is a common prior art, it will not be elaborated here, and it is only briefly shown in the drawings.

[0076] Referring to Figure 3 and Figure 6 , at this time, by filling air into or sucking air out of the corresponding sealed space 3121 through the nozzle 433, the corresponding plurality of first movable members 412 or the plurality of second movable members 422 can be driven to move relative to the frame 31, so that it is convenient for the staff to adjust the size of the space for installing the gas generator set 2 in the installation space 311, and at the same time, it is convenient for the staff to adjust the degree of extrusion of the plurality of first elastic members 413 and the plurality of second elastic members 423 after the gas generator set 2 is installed, so as to adjust the vibration reduction effect of the plurality of first elastic members 413 and the plurality of second elastic members 423 on the gas generator set 2. In this embodiment, preferably, after air is filled into the sealed space 3121 through the nozzle 433, the rotating member 431 can still maintain the tendency to rotate to the position state with the length direction horizontal under the action of the third elastic member 432.

[0077] During the vibration of the gas generator set 2, the staff can know whether the third elastic member 432 stably exerts its effect of driving the rotating member 431 to rotate through the positions of the two air nozzles 433. At the same time, the staff can judge whether the vibration damping effect of the vibration damping device 4 on the gas generator set 2 is sufficient according to the degree of change of the positions of the two air nozzles 433 as the rotating member 431 rotates, so as to facilitate the staff to adjust the vibration damping effect that the vibration damping device 4 can achieve on the gas generator set 2 in a timely manner.

[0078] Refer to Figure 3 and Figure 4 As shown in FIGS. 5 and 6, the leveling device 5 includes a leveling member 51, a plurality of spirit levels 52, two elastic pads 53 and a blowing assembly 54.

[0079] An installation groove 321 adapted to the bottom of the gas generator set 2 is formed at the top of the support member 32. The two elastic pads 53 are both installed in the installation groove 321, and the leveling member 51 is detachably connected to the top of the support member 32.

[0080] The leveling member 51 is integrally in the shape of a rectangular plate with a hollow middle. After the leveling member 51 is installed on the support member 32, the length direction of the leveling member 51 is parallel to the length direction of the support member 32 and its width direction is also parallel to the width direction of the support member 32. A part of the leveling member 51 will be located above the installation groove 321, and the hollow middle area of the leveling member 51 will provide a clearance for the gas generator set 2. In this embodiment, it is preferably that the rectangular size of the leveling member 51 is the same as the rectangular size of the support member 32, and it is preferably that the leveling member 51 is detachably connected to the support member 32 through a plurality of bolts; since the detachable connection through bolts is a common prior art, it will not be described in detail here, and it is omitted in the drawings.

[0081] After the gas generator set 2 is installed, its bottom will be clamped and positioned between the leveling member 51 and the elastic pad 53. The elastic pad 53 will be in a state of being squeezed and deformed, and the acting force of the squeezed and deformed elastic pad 53 on the bottom of the gas generator set 2 over time can make it keep in close contact with the leveling member 51, so that the gas generator set 2 can keep its installation position at a certain levelness with the help of the leveling member 51; at the same time, when the gas generator set 2 vibrates during operation, the elastic pad 53 can absorb part of the vibration, so as to further reduce the influence caused by the vibration of the gas generator set 2.

[0082] The spirit level 52 is fixedly installed on the leveling member 51. After the leveling member 51 is installed on the support member 32, the spirit level 52 will be located at the top of the leveling member 51. In this embodiment, since the gas generator set 2 vibrates during operation, it is preferably that the spirit level 52 is a spirit level 52 with a certain anti-vibration effect, such as an electronic spirit level 52, etc.

[0083] Refer toFigure 1 and Figure 3 Furthermore, preferably, the leveling device 5 includes a total of four spirit levels 52, and the four spirit levels 52 are respectively installed around the leveling member 51; after the spirit level 52 is installed on the leveling member 51, the length direction thereof is parallel to the length direction of the corresponding side of the adjacent leveling member 51, and it can measure the levelness of the leveling member 51 along its own length direction.

[0084] At this time, the staff can determine the levelness of the leveling member 51 installed on the support member 32 according to the spirit level 52, and can also determine the levelness of the gas generator set 2 fixedly installed on the ground 1 through the support device 3 according to the spirit level 52; during the vibration of the gas generator set 2 during operation, the elastic pad 53 can make the levelness of the installation position of the gas generator set 2 remain close to the levelness of the installation of the leveling member 51, and the spirit level 52 can reflect the change in the levelness of the leveling member 51 during this process, so as to facilitate the staff to judge the change in the levelness of the installation position of the gas generator set 2 during its operation. In this embodiment, preferably, the spirit level 52 has an alarm function and can issue an alarm when the levelness of the leveling member 51 measured by it is lower than a certain value, so as to facilitate the staff to timely know the change in the levelness of the installation position of the gas generator set 2 during its operation; since the spirit level 52 with the above functions is a common prior art, it will not be elaborated here, and it is only briefly shown in the drawings.

[0085] Furthermore, to facilitate the staff to observe the measurement data of the four spirit levels 52 during the installation and operation of the gas generator set 2, preferably, observation ports 313 communicating with the installation space 311 are opened on both sides in the width direction of the frame body 31, so as to facilitate the staff to observe the measurement data on the four spirit levels 52 respectively around the frame body 31.

[0086] Refer to Figure 3 and Figure 4 The air blowing assembly 54 is installed on the support member 32 and includes a blower 541 and a one-way valve 542.

[0087] Two elastic pads 53 are distributed in the installation groove 321 in a vertically stacked manner, and the inner part of the elastic pad 53 at the bottom has a sealed air cavity 531; a blower 541 is fixedly installed on one side in the width direction of the support member 32, and a trachea extends outward through the support member 32 in the direction close to the installation groove 321, and the trachea penetrates into the inner part of the elastic pad 53 at the bottom and communicates with the air cavity 531; a one-way air valve 542 is fixedly installed on the trachea extending from the blower 541, and is used to limit the gas to only enter the air cavity 531 through the blower 541, and cannot leave the air cavity 531 through the trachea. In this embodiment, since the blowing assembly 54 with the above functions is a common prior art, it will not be elaborated here, and it is only briefly shown in the drawings.

[0088] The blower 541 is signal-connected to the gas generator set 2. When the gas generator set 2 works, it will trigger the blower 541 to operate, so that the blower 541 maintains the tendency to drive gas into the air cavity 531 during the operation of the gas generator set 2, so that the two elastic pads 53 at the bottom of the gas generator set 2 maintain the effect of driving the bottom of the gas generator set 2 to fit against the leveling member 51.

[0089] At this time, when the gas generator set 2 vibrates during operation and causes damage to the elastic pad 53, so that the effect of the two elastic pads 53 driving the bottom of the gas generator set 2 to fit against the leveling member 51 is weakened, the blowing assembly 54 can timely blow gas into the inner part of the elastic pad 53 at the bottom, so that the two elastic pads 53 restore the effect of driving the bottom of the gas generator set 2 to fit against the leveling member 51, and thus can effectively ensure that the gas generator set 2 maintains a high level of installation position during operation.

[0090] The implementation principle of the installation structure of a gas generator set for combined heat and power (CHP) in an embodiment of the present application is as follows:

[0091] First, install and fix the bracket on the ground 1 with a certain levelness. During this process, the levelness of the bracket installed on the ground 1 is judged and adjusted through a plurality of spirit levels 52 pre-installed on the support member 32;

[0092] Then install the gas generator set 2 in the installation space 311, so that a fixed connection is formed between the bottom of the gas generator set 2 and the support member 32 and a fixed connection is formed between its top and the limiting member 33. Then, control the gas to enter and exit the two sealed spaces 3121 through the two air nozzles 433, so as to respectively adjust the vibration damping effects of the first vibration damping assembly 41 and the second vibration damping assembly 42 on the gas generator set 2; then, pre-control the blowing assembly 54 to work, so that the two elastic pads 53 drive the bottom of the gas generator set 2 to fit against the leveling member 51 to ensure the levelness of the installation of the gas generator set 2;

[0093] After that, during the vibration of the gas generator set 2 during operation, both the first vibration damping assembly 41 and the second vibration damping assembly 42 can directly achieve the vibration damping effect on the gas generator set 2, and the linkage assembly 43 can enable a linkage to be formed between the first vibration damping assembly 41 and the second vibration damping assembly 42, thereby effectively reducing the tendency of the gas generator set 2 to have a small displacement due to vibration; at the same time, the spirit level 52 can reflect in real time the change in the level of the installation position of the gas generator set 2 during operation, facilitating the staff to take timely measures when the installation level of the gas generator set 2 is relatively low; and, the elastic pad 53 located below the gas generator set 2 can also absorb part of the vibration, and at the same time can make the bottom of the gas generator set 2 keep in contact with and against the leveling member 51 under the action of the air blowing assembly 54, further ensuring the levelness of the gas generator set 2 during operation, so as to effectively reduce the probability of the gas generator set 2 being damaged due to low levelness or even causing a safety accident during operation.

[0094] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
