Description

Technical Field

[0001] This utility model relates to the field of steam turbine insulation sleeves, and in particular to a novel steam turbine noise reduction insulation sleeve. Background Technology

[0002] The development of a new type of noise-reducing insulation jacket for steam turbines is primarily driven by the significant heat and noise generated during turbine operation. While traditional insulation jackets can reduce heat loss, they are ineffective at noise reduction, which not only harms the health of workers but also causes environmental pollution. Furthermore, with the advancement of energy conservation and emission reduction policies, higher demands are being placed on the insulation and noise reduction of steam turbines. Against this backdrop, the new noise-reducing insulation jacket for steam turbines has emerged to achieve the dual functions of insulation and noise reduction, meeting both environmental protection and production needs.

[0003] In existing technologies, turbine noise reduction and insulation jackets need to be pre-made according to the size and fit of the turbine itself before use. Since turbine noise reduction and insulation jackets are usually integrated, when a part of the turbine noise reduction and insulation jacket is damaged or a certain area of ​​the insulation jacket needs to be replaced, it is impossible to disassemble that part or area of ​​the insulation jacket, which leads to the need to replace the entire insulation jacket during maintenance, increasing costs. Therefore, a new type of turbine noise reduction and insulation jacket is proposed. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A novel steam turbine noise reduction and heat insulation sleeve includes: a main shell mechanism, at least one connecting mechanism, and a noise reduction mechanism;

[0006] At least one of the connecting mechanisms is located on the side of the main housing mechanism;

[0007] It includes: a connecting ring, at least two sets of placement cavities, with two in each set, a pull rod, at least one L-shaped locking block I, at least one L-shaped locking block II, and at least one elastic element I. The connecting ring is connected to the side of the main housing mechanism, the at least two sets of placement cavities are formed on the side of the connecting ring, the pull rod is connected to the inside of the placement cavity, at least one L-shaped locking block I is connected to the lower surface of the pull rod, and at least one elastic element I is disposed inside the placement cavity, with one end of the elastic element I connected to the inside of the placement cavity and the other end of the elastic element I connected to the upper surface of the L-shaped locking block I.

[0008] The above-described technical solution describes a novel turbine noise reduction and insulation jacket consisting of a main shell mechanism, a connecting mechanism, and a noise reduction mechanism. The connecting mechanism is located on the side of the main shell mechanism, enabling a stable connection with the turbine components, facilitating installation and disassembly, improving maintenance efficiency, and laying the foundation for the stable operation of the overall equipment.

[0009] As a further description of the above technical solution:

[0010] The main shell mechanism includes an outer shell, a connector, at least one tail shell, and an inner shell. The outer shell is connected to the side of the connecting ring, the connector is connected to the side of the outer shell, and the inner shell is disposed inside the outer shell.

[0011] The aforementioned technical solution utilizes a connecting mechanism comprised of a connecting ring, a placement cavity, and a tie rod. This mechanism, through an elastic element, pushes a novel turbine noise-reducing and heat-insulating sleeve L-shaped locking block, achieving rapid engagement with the turbine. This structure provides a robust connection, adapts to turbines of different sizes, and is easy to disassemble, effectively reducing installation and maintenance costs.

[0012] As a further description of the above technical solution:

[0013] The noise reduction mechanism is disposed inside the main shell mechanism;

[0014] It includes: two sets of partition rings, with two partition rings in each set, and two elastic elements. Both sets of partition rings are disposed at the left and right ends of the inner shell. The two elastic elements are disposed between the sets of partition rings. One end of the two elastic elements is connected to the outer surface of the inner shell, and the other end of at least one of the two elastic elements is connected to the inner surface of the outer shell.

[0015] The above technical solution involves the main shell mechanism's outer shell, connecting component one, tail shell, and inner shell working together. The outer shell provides wear protection, the inner shell provides efficient heat insulation, connecting component one enhances structural stability, and the tail shell provides auxiliary connection, all working together to prevent heat loss from the turbine and extend the equipment's service life.

[0016] As a further description of the above technical solution:

[0017] At least one of the tail shells is connected to the side of the connecting ring away from the connecting member one, and at least one of the L-shaped locking blocks two is connected to the outside of the tail shell.

[0018] In the above technical solution, the noise reduction mechanism consists of a partition ring and an elastic element 2 working together. The partition ring fixes the elastic element 2, which absorbs the vibration of the steam turbine operation, reduces noise transmission, buffers vibration, reduces component wear, and creates a quiet operating environment.

[0019] As a further description of the above technical solution:

[0020] The two sets of separating rings are located on the same horizontal plane, and at least one L-shaped locking block is slidably connected inside.

[0021] The above technical solution involves the tail shell cooperating with a novel turbine noise reduction and heat insulation sleeve L-shaped locking block II. Through sliding connection, precise positioning and stable installation are achieved, ensuring that the main shell mechanism fits tightly with the turbine, preventing heat leakage and noise dissipation, and improving the overall performance of the noise reduction and heat insulation sleeve.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by pulling the pull rod outward, the pull rod causes the L-shaped locking block to move in the pulling direction. Since the two ends of the L-shaped locking block have their own rotating shafts, and the pull rod is connected at the front end of the upper surface of the L-shaped locking block, the pulling force provided by the pull rod causes the L-shaped locking block to rotate upward, increasing the activity space inside the placement cavity. Therefore, the L-shaped locking block 2, which is engaged with the L-shaped locking block 1, can be disengaged. This structure achieves the effect of free disassembly of the outer shell and the tail shell, solving the problem of needing to replace the entire insulation sleeve and increasing costs during maintenance in the prior art.

[0024] 2. In this invention, when the vibration and noise generated by the steam turbine are transmitted to the inner shell, the elastic element two has the function of storing elastic force. Therefore, the vibration force is transmitted to the elastic element two, stored by the elastic element two, and then released naturally. Through the deformation property of the elastic element two itself, the vibration force and noise are weakened. This structure achieves the effect of reducing vibration force and solves the problem of high noise caused by the large vibration amplitude generated by the steam turbine during operation in the prior art.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figure 2 , Figure 5 , Figure 6 , Figure 7 One embodiment of this utility model is a novel steam turbine noise reduction and heat insulation sleeve, comprising: a main shell mechanism 100, at least one connecting mechanism 200, and a noise reduction mechanism 300.

[0038] At least one connecting mechanism 200 is located on the side of the main housing mechanism 100;

[0039] It includes: a connecting ring 201, at least two sets of placement cavities 202 (each set consisting of two cavities), a pull rod 203, at least one L-shaped locking block 204, at least one L-shaped locking block 205, and at least one elastic element 206. The connecting ring 201 is connected to the side of the main housing mechanism 100. The at least two sets of placement cavities 202 are formed on the side of the connecting ring 201. The pull rod 203 is connected inside the placement cavity 202. At least one L-shaped locking block 204 is connected to the lower surface of the pull rod 203. At least one elastic element 206 is disposed inside the placement cavity 202. One end of the elastic element 206 is connected to the inside of the placement cavity 202, and the other end of the elastic element 206 is connected to the upper surface of the L-shaped locking block 204.

[0040] In the above embodiment, when a certain area of ​​the device is damaged and needs repair, the operator simultaneously pulls the lever 203 outward, causing the lever 203 to move the L-shaped locking block 204 in the pulling direction. Since the two ends of the L-shaped locking block 204 have their own rotating shafts, and the lever 203 is connected at the front end of the upper surface of the L-shaped locking block 204, the pulling force provided by the lever 203 causes the L-shaped locking block 204 to rotate upward, increasing the activity space inside the placement cavity 202. As a result, the L-shaped locking block 205 that is engaged with the L-shaped locking block 204 can be disengaged, making the subsequent disassembly steps more convenient.

[0041] Reference Figures 2 to 4 The main shell mechanism 100 includes an outer shell 101, a connector 102, at least one tail shell 103, and an inner shell 104. The outer shell 101 is connected to the side of the connecting ring 201, the connector 102 is connected to the side of the outer shell 101, and the inner shell 104 is disposed inside the outer shell 101.

[0042] In the above embodiment, the noise reduction function is enhanced by placing a sound-insulating filler in the space between the inner shell 104 and the outer shell 101. The inner shell 104 is set inside the outer shell 101 to form a composite space. The outer shell 101, inner shell 104 and tail shell 103 are all made of high-temperature resistant materials, so that the heat generated by the turbine operation can be stored in the device and the heat loss is reduced.

[0043] Reference Figure 2 , Figure 3 The noise reduction mechanism 300 is located inside the main shell mechanism 100;

[0044] It includes: two sets of partition rings 301, with two partition rings 301 in each set, and a second elastic element 302. Both sets of partition rings 301 are disposed at the left and right ends of the inner shell 104, and the second elastic element 302 is disposed between the partition rings 301. One end of the second elastic element 302 is connected to the outer surface of the inner shell 104, and the other end of at least one second elastic element 302 is connected to the inner surface of the outer shell 101.

[0045] In the above embodiment, when the vibration and noise generated by the steam turbine are transmitted to the inner shell 104, the elastic element 302 has the function of storing elastic force. Therefore, the vibration force is transmitted to the elastic element 302, stored by the elastic element 302, and then released naturally. Through the deformation property of the elastic element 302 itself, the vibration force and noise are weakened.

[0046] Reference Figure 3 , Figure 6 At least one tail shell 103 is connected to the side of the connecting ring 201 away from the connector 102, and at least one L-shaped locking block 205 is connected to the outside of the tail shell 103.

[0047] In the above embodiment, when it is necessary to connect tail shells 103 of different shapes or sizes to the outer shell 101, the L-shaped locking block 205 on the tail shell 103 is aligned with the position of the placement cavity 202 and pressed down. Since the L-shaped locking block 1 204 and the L-shaped locking block 205 are L-shaped hooks, when the L-shaped locking block 205 is pressed down, the hook part of the L-shaped locking block 205 pushes the lower surface of the L-shaped locking block 1 204, causing the L-shaped locking block 1 204 to rotate under the stored elastic force of the elastic member 206. At the same time, the elastic member 206 restores its deformation, so the L-shaped locking block 205 can be locked in the hook part of the L-shaped locking block 1 204.

[0048] Reference Figure 3 , Figure 6 Two sets of separating rings 301 are located on the same horizontal plane, and at least one L-shaped card block 205 is slidably connected inside the placement cavity 202.

[0049] In the above embodiment, in order to ensure that the L-shaped card block 205 is inserted into the placement cavity 202 without obstruction, the positions of the L-shaped card block 205 and the placement cavity 202 need to correspond.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
