Description

Technical Field

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

[0002] Combined heat and power (CHP) is an efficient energy utilization technology that generates electricity and heat at the same time. Its core is to achieve the output of two energies through a single energy input, thereby improving overall efficiency. Among them, gas generator sets have both power generation and heat recovery functions in combined heat and power, which significantly improves energy efficiency, reduces emissions, and has flexibility and economy. It is the core component of the CHP system.

[0003] Currently, the gas generator set in cogeneration is usually fixedly mounted on an I-beam bracket, which is fixedly connected to the ground by multiple bolts, so that the installation structure of the gas generator set is closely related to the working efficiency of the gas generator set in the cogeneration process.

[0004] However, the gas generator set will generate vibration when working, which will cause great damage to the I-beam support. When the I-beam support is loosened due to vibration, it will cause the gas generator set to generate greater vibration when working, which will not only affect the efficiency of cogeneration, but also easily cause the gas generator set to malfunction and damage, and may even pose a major safety hazard.

In this embodiment, the gas generator set 2 is preferably a structure with a shell, and its overall structure is a rectangular parallelepiped; since the gas generator set of combined heat and power is equipped with a shell, which is a prior art in the field, it will not be described here, and it is only briefly represented in the drawings.

[0031] Reference Figure 1 and Figure 3 The 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.

[0032] The supporting device 3 includes a frame 31 , a supporting member 32 and a limiting member 33 .

[0033] 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.

[0034] 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.

[0035] The gas generator set 2 is installed between the support member 32 and the stopper 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 stopper 33; the vibration of the gas generator set 2 during operation will cause it to have a tendency to slightly displace, and at this time, due to the limitation of the movable connection between the support member 32 and the stopper 33 and the frame 31, the gas generator set 2 can only have a tendency to slightly displace along the height direction of the frame 31. In this embodiment, after the support device 3 is preferably installed on the ground 1, the support member 32 and the stopper 33 are aligned in the vertical direction; and when the gas generator set 2 vibrates during operation and has a tendency to slightly displace, it can simultaneously drive the support member 32 and the stopper 33 to have a tendency to slightly displace in the same direction.

[0036] Reference Figure 3 and Figure 4 The vibration reduction device 4 includes a first vibration reduction component 41 and a second vibration reduction component 42. The first vibration reduction component 41 and the second vibration reduction component 42 are respectively located at the bottom and the top of the installation space 311, and are respectively used to reduce vibrations on the support member 32 and the limit member 33.

[0037] Reference Figure 3 and Figure 5 The first vibration reduction assembly 41 includes a plurality of first fixing members 411 , a plurality of first movable members 412 and a plurality of first elastic members 413 , which correspond to each other.

[0038] The first fixing member 411 is fixedly installed at the bottom of the frame 31 and is located at the bottom of the installation space 311, and multiple first fixing members 411 are evenly distributed in a rectangular array on the inner wall at the bottom of the installation space 311; the first fixing member 411 is designed to be hollow inside, one end of the first movable member 412 is fitted with the first fixing member 411 and is movably connected with the first fixing member 411 in a direction parallel to the height direction of the frame 31, and the other end of the first movable member 412 remains on the side of the corresponding first fixing member 411 close to the center of the installation space 311 during the movement of the first movable member 412 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 fixedly connected to the corresponding first fixing member 411 and the corresponding first movable member 412 respectively, and it has a tendency to drive the corresponding first movable member 412 to move relative to the corresponding first fixing member 411 in a direction close to the center of the installation space 311 to an extreme position and maintain it. In this embodiment, the first elastic member 413 is preferably 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.

[0039] The second vibration reduction 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 corresponding to each other.

[0040] The second fixing member 421 is fixedly installed on the top of the frame 31 and is located at the top of the installation space 311, and multiple second fixing members 421 are evenly distributed in a rectangular array on the inner wall of the top of the installation space 311; the interior of the second fixing member 421 is hollow, one end of the second movable member 422 is penetrated and matched with the second fixing member 421 and is movably connected with the second fixing member 421 in a direction parallel to the height direction of the frame 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 of the installation space 311 during the movement of the second movable member 422 relative to the corresponding second fixing member 421, and a fixed connection is formed between it and the limit member 33; the second elastic member 423 is installed inside the corresponding second fixing member 421, and its two ends are fixedly connected to the corresponding second fixing member 421 and the corresponding second movable member 422 respectively, and it has a tendency to drive the corresponding second movable member 422 to move relative to the corresponding second fixing member 421 in the direction close to the center of the installation space 311 to the extreme position and maintain it. In this embodiment, the second elastic member 423 is preferably a spring, and after the gas generator set 2 is installed, the multiple second elastic members 423 will be in a squeezed state; and the multiple second fixing members 421 and the multiple second movable members 422 of the second vibration damping assembly 42 are preferably respectively corresponding to the multiple first fixing members 411 and the multiple second movable members 422 of the first vibration damping assembly 41 along the height direction of the frame 31.

[0041] 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 an extruded state can absorb part of the vibration of the gas generator set 2, thereby effectively reducing the vibration occurring during operation of the gas generator set 2.

[0042] Furthermore, in order to ensure the horizontality of the installation position of the gas generator set 2 during operation and vibration, and to reduce the impact of vibration on the horizontality of its installation position, the first vibration damping assembly 41 preferably also includes a first synchronization plate 414, and the second vibration damping assembly 42 preferably also includes a second synchronization plate 424.

[0043] The first synchronization plate 414 is a rectangular plate-shaped structure as a whole, and the ends of the plurality of first movable members 412 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 plurality of first movable members 412 are fixedly connected to the support member 32 through the first synchronization plate 414. In this embodiment, the rectangular dimensions of the first synchronization plate 414 and the support member 32 are preferably equal; and the first synchronization plate 414 and the support member 32 are preferably fixedly connected by a plurality of bolts; since the fixed connection by bolts is a common prior art, it will not be described in detail here, and the bolts and related structures are omitted in the drawings.

[0044] The second synchronization plate 424 is a rectangular plate-shaped structure as a whole, and the ends of the plurality of second movable members 422 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 stopper 33, so that the plurality of second movable members 422 are fixedly connected to the stopper 33 through the second synchronization plate 424. In this embodiment, the second synchronization plate 424 and the stopper 33 are preferably of equal rectangular size; and the second synchronization plate 424 and the stopper 33 are preferably fixedly connected by a plurality of bolts; since the fixed connection by bolts is a common prior art, it will not be described in detail here, and the bolts and related structures are omitted in the drawings.

[0045] 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 an extruded state can have a uniform vibration reduction effect on the gas generator set 2 under the action of the first synchronization plate 414 and the second synchronization plate 424 respectively, and at the same time can make the gas generator set 2 vibrate more evenly during operation to ensure that it maintains a high level during operation.

[0046] Reference Figure 2 and Figure 6 Furthermore, in order to further improve the vibration reduction effect of the vibration reduction device 4 on the gas generator set 2 during operation, the vibration reduction device 4 preferably also includes a linkage component 43.

[0047] The linkage assembly 43 includes a rotating member 431 , a third elastic member 432 and two air nozzles 433 .

[0048] Reference Figure 3 and Figure 5 A cavity 312 is opened inside the structure of the frame 31, and the cavity 312 is distributed at the top of the frame 31, one side in the width direction of the frame 31 and the bottom of the frame 31; one end of the bottom of the cavity 312 is communicated with the internal space of multiple first fixing parts 411 at the same time, and is sealed by multiple first movable parts 412 at the same time; one end of the top of the cavity 312 is communicated with the internal space of multiple second fixing parts 421 at the same time, and is sealed by multiple second movable parts 422 at the same time.

[0049] Reference Figure 2 and Figure 6 The rotating member 431 is rotatably installed inside one side of the frame 31 in the width direction and is located in the cavity 312. Its rotation axis is parallel to the width direction of the frame 31, and during its rotation, it keeps the cavity 312 separated to form two corresponding sealed spaces 3121 and two rotating spaces 3122.

[0050] The sealed space 3121 is adjacent to the corresponding rotating space 3122 near the rotating member 431 and is separated by one end of the rotating member 431 in the length direction; the sealed space 3121 is also adjacent to another rotating space 3122 near the rotating member 431 and is separated by the entire rotating member 431.

[0051] The rotating member 431 is limited by the size of the rotating space 3122 during the rotation of the cavity 312, and the size of the sealed space 3121 and the size of the rotating space 3122 both change during the rotation of the rotating member 431; when the rotating member 431 rotates to the point where the volume of the rotating space 3122 is the largest, the rotating member 431 is in a horizontal position in the length direction, and the volume of the sealed space 3121 is the smallest. During the rotation of the rotating member 431 relative to the frame 31, the volume changes of the two sealed spaces 3121 have the same trend and the same amount, and the volume changes of the two rotating spaces 3122 have the same trend and the same amount.

[0052] The two ends of the third elastic member 432 are fixedly connected to the rotating member 431 and the frame 31, respectively, and have a tendency to drive the rotating member 431 to rotate to and maintain the position state where the volume of the rotating space 3122 is the largest. In this embodiment, the third elastic member 432 is preferably a torsion spring; since the torsion spring is a common prior art, it is not described in detail here, and the drawings only show the installation position of the third elastic member 432 and omit the structure thereof.

[0053] Reference 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 horizontal position in the length direction under the action of the third elastic member 432; at this time, when the gas generator set 2 vibrates during operation, the gas generator set 2 will undergo a slight displacement relative to the frame 31 along the height direction of the frame 31, and the volumes of the two sealed spaces 3121 will change accordingly and the change trends are opposite. When the volume of one sealed space 3121 changes, the rotating member 431 will be driven to rotate relative to the frame 31 and the volume of the other sealed space 3121 will be driven to change in the same trend; since the trend of one sealed space 3121 driving the volume of the other sealed space 3121 to change with the vibration displacement of the gas generator set 2 is opposite to the trend of the rotating member 431 rotating with the vibration displacement of the gas generator set 2 to drive the volume of the other sealed space 3121 to change, the linkage assembly 43 can effectively suppress the displacement of the gas generator set 2 due to vibration.

[0054] Reference Figure 2 and Figure 6, the rotating member 431 is partially exposed on one side of the width direction of the frame 31, and the rotating member 431 can maintain its sealing effect on the cavity 312 during the rotation process; the two gas nozzles 433 are fixedly installed on the rotating member 431, and the two gas nozzles 433 are respectively connected to the two sealed spaces 3121, and the gas nozzles 433 are used to control the gas to enter and exit the corresponding sealed space 3121; one end of the gas nozzle 433 is connected to the corresponding sealed space 3121, and the other end of the gas nozzle 433 is located on the 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, it is preferred that the gas nozzle 433 can change the connection state between the sealed space 3121 and the outside world according to needs; since the gas nozzle 433 with the above-mentioned function is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0055] Reference Figure 3 and Figure 6 At this time, the corresponding multiple first movable members 412 or multiple second movable members 422 can be driven to move relative to the frame 31 by filling air into or sucking out air from the corresponding sealed space 3121 through the air nozzle 433, so that the staff can adjust the size of the space for installing the gas generator set 2 in the installation space 311, and at the same time, the staff can adjust the degree of compression of the multiple first elastic members 413 and the multiple second elastic members 423 after the gas generator set 2 is installed, so as to adjust the vibration reduction effect of the multiple first elastic members 413 and the multiple second elastic members 423 on the gas generator set 2. In this embodiment, after the air is filled into the sealed space 3121 through the air nozzle 433, the rotating member 431 can still maintain a tendency to rotate to a horizontal position in the length direction under the action of the third elastic member 432.

[0056] During the operation of the gas generator set 2 and the vibration thereof, 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, and at the same time can judge whether the vibration reduction effect of the vibration reduction device 4 on the gas generator set 2 is sufficient through the degree to which the positions of the two air nozzles 433 change with the rotation of the rotating member 431, thereby facilitating the staff to timely adjust the vibration reduction effect of the vibration reduction device 4 on the gas generator set 2.

[0057] Reference Figure 3 and Figure 4 The leveling device 5 includes a leveling member 51 , a plurality of level gauges 52 , two elastic pads 53 and a blowing assembly 54 .

[0058] The top of the support member 32 is provided with a mounting groove 321 adapted to the bottom of the gas generator set 2 , the two elastic pads 53 are both installed in the mounting groove 321 , and the leveling member 51 is detachably connected to the top of the support member 32 .

[0059] The leveling member 51 is a rectangular plate-shaped structure with a hollow center. 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 the width direction is also parallel to the width direction of the support member 32. Part of the leveling member 51 will be located above the installation groove 321, and the middle hollow area of ​​the leveling member 51 will provide space for the gas generator set 2. In this embodiment, the rectangular size of the leveling member 51 is preferably the same as the rectangular size of the support member 32, and the leveling member 51 is preferably detachably connected to the support member 32 by multiple bolts; since the detachable connection by bolts is a common prior art, it will not be described in detail here, and it is omitted in the drawings.

[0060] After the gas generator set 2 is installed, its bottom will be clamped and positioned between the leveling piece 51 and the elastic pad 53. The elastic pad 53 will be in a state of being squeezed and deformed, and the force exerted by the squeezed and deformed elastic pad 53 on the bottom of the gas generator set 2 can keep it in contact with the leveling piece 51, so that the gas generator set 2 can use the leveling piece 51 to keep its installation position at a certain level; at the same time, when the gas generator set 2 vibrates during operation, the elastic pad 53 can absorb part of the vibration, thereby further reducing the impact of the vibration of the gas generator set 2.

[0061] The level 52 is fixedly mounted on the leveling member 51. After the leveling member 51 is mounted on the support member 32, the 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, the level 52 is preferably a level 52 with a certain anti-vibration effect, such as an electronic level 52.

[0062] Reference Figure 1 and Figure 3 Furthermore, it is preferred that the horizontal device 5 includes four spirit levels 52, and the four spirit levels 52 are respectively installed on the four sides of the leveling member 51; after the spirit level 52 is installed on the leveling member 51, its length direction is parallel to the length direction of the side corresponding to the adjacent leveling member 51, and it can measure the horizontality of the leveling member 51 along its own length direction.

[0063] At this time, the staff can determine the level of the leveling member 51 installed on the support member 32 according to the level meter 52, and can also determine the level of the gas generator set 2 fixedly installed on the ground 1 through the support device 3 according to the level meter 52; during the vibration of the gas generator set 2 during operation, the elastic pad 53 can keep the level of the installation position of the gas generator set 2 close to the level of the leveling member 51, and the level meter 52 can reflect the change of the level of the leveling member 51 during this process, so as to facilitate the staff to judge the change of the level of the installation position of the gas generator set 2 during its operation. In this embodiment, it is preferred that the level meter 52 has an alarm function, which can issue an alarm when it measures that the level of the leveling member 51 is lower than a certain value, so that the staff can promptly know the change of the level of the installation position of the gas generator set 2 during its operation; since the level meter 52 with the above function is a common prior art, it will not be described in detail here, and it is only briefly shown in the attached drawings.

[0064] Furthermore, in order to facilitate the staff to observe the measurement data of the four levels 52 during the installation and operation of the gas generator set 2, it is preferred that observation ports 313 connected to the installation space 311 are opened on both sides of the width direction of the frame 31, so that the staff can observe the measurement data on the four levels 52 respectively around the frame 31.

[0065] Reference Figure 3 and Figure 4 The blowing assembly 54 is installed on the supporting member 32 and includes an air blower 541 and a one-way air valve 542 .

[0066] Two elastic pads 53 are distributed in the installation groove 321 in a vertically stacked manner, and the elastic pad 53 at the bottom has a sealed air cavity 531 inside; the blower 541 is fixedly installed on one side of the width direction of the support member 32, and an air pipe extends outward through the support member 32 in the direction close to the installation groove 321, and the air pipe penetrates the interior of the elastic pad 53 at the bottom and communicates with the air cavity 531; the one-way air valve 542 is fixedly installed on the air pipe 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 air pipe. In this embodiment, since the blowing component 54 with the above functions is a common prior art, it will not be described here in detail, and it is only briefly shown in the drawings.

[0067] The blower 541 is connected to the gas generator set 2 signal, and the blower 541 will be triggered to run when the gas generator set 2 is working, so that the blower 541 will maintain the tendency of driving gas into the air cavity 531 during the operation of the gas generator set 2, so that the two elastic pads 53 located at the bottom of the gas generator set 2 will maintain the effect of driving the bottom of the gas generator set 2 to fit against the leveling member 51.

[0068] At this time, when the gas generator set 2 vibrates during operation and causes the elastic pad 53 to be damaged, thereby weakening the effect of the two elastic pads 53 driving the bottom of the gas generator set 2 to fit and resist the leveling piece 51, the blowing assembly 54 can promptly blow gas into the elastic pad 53 at the bottom, so that the two elastic pads 53 can restore the effect of driving the bottom of the gas generator set 2 to fit and resist the leveling piece 51, thereby effectively ensuring that the gas generator set 2 maintains a relatively high level of the installation position during operation.

[0069] The implementation principle of the installation structure of a combined heat and power (CHP) gas generator set in the embodiment of the present application is: First, the bracket is installed and fixed on the ground 1 at a certain level. During this process, the level of the bracket installed on the ground 1 is judged and adjusted by using multiple level gauges 52 pre-installed on the support member 32; Then install the gas generator set 2 in the installation space 311, so that 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 stop member 33, and then control the gas to enter and exit the two sealed spaces 3121 through the two air nozzles 433, so as to adjust the vibration reduction effects of the first vibration reduction assembly 41 and the second vibration reduction assembly 42 on the gas generator set 2 respectively; then, control the blowing assembly 54 to work in advance, so that the two elastic pads 53 drive the bottom of the gas generator set 2 to fit against the leveling member 51, so as to ensure the horizontality of the gas generator set 2; Afterwards, during the operation of the gas generator set 2 and the vibration, the first vibration reduction component 41 and the second vibration reduction component 42 can directly reduce the vibration of the gas generator set 2, and the linkage component 43 can form a linkage between the first vibration reduction component 41 and the second vibration reduction component 42, thereby effectively reducing the tendency of the gas generator set 2 to have a slight displacement due to vibration; at the same time, the level 52 can reflect the change of the horizontality of the installation position of the gas generator set 2 in real time during the operation of the gas generator set 2, so that the staff can take timely measures when the installation level of the gas generator set 2 is low; and the elastic pad 53 located under the gas generator set 2 can also absorb part of the vibration, and at the same time, under the action of the blowing component 54, the bottom of the gas generator set 2 can be kept in contact with the leveling member 51, further ensuring the levelness of the gas generator set 2 during operation, so as to effectively reduce the probability of failure and damage of the gas generator set 2 due to low levelness during operation, or even causing a safety accident.

[0070] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
