Description

Technical Field

[0001] This utility model relates to the technical field of distributed control logic modules, and in particular to a fixing device for an intelligent distributed control logic module in a hydropower plant. Background Technology

[0002] In the operation system of hydropower plants, intelligent distributed control logic modules play a crucial role, and their stable installation and convenient maintenance are essential for the efficient operation of hydropower plants. Currently, when fixing intelligent distributed control logic modules in hydropower plants, existing technologies mostly use elastic clips or screws as fixing methods.

[0003] While using elastic clips for fixing offers some convenience during installation, allowing for relatively quick placement of the control logic module onto the fixing device, the disassembly process is time-consuming due to the large number of clips that need to be opened one by one. This also places high demands on the operator's patience and precision. In emergency repairs or equipment upgrades, this cumbersome disassembly process can severely delay work progress, increase hydropower plant downtime, and consequently affect overall power generation efficiency and economic benefits.

[0004] While bolt fixing provides a relatively stable fixation, it also faces the problem of inconvenient disassembly. Each bolt requires tools to loosen, and with a large number of bolts, the disassembly process is extremely time-consuming and laborious. Frequent disassembly over a long period of time may also lead to stripped bolt threads and damaged bolt holes, further increasing the cost and difficulty of equipment maintenance. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a fixing device for intelligent distributed control logic modules in hydropower plants, which solves the inconvenience of disassembly in existing fixing methods, improves equipment maintenance efficiency, and reduces maintenance costs.

[0006] The present invention relates to a fixing device for a smart distributed control logic module in a hydropower plant, comprising a distributed control logic module body and a mounting plate; the mounting plate is provided with a snap-fit ​​assembly, and the distributed control logic module body is provided with a through hole that cooperates with the snap-fit ​​assembly;

[0007] The snap-fit ​​assembly includes: at least one elastic element that is fixedly connected to the mounting plate; the elastic element includes a head and a connecting part, the connecting part is located in a through hole, and the head protrudes from the position of the connecting part and is locked with the main body of the distributed control logic module;

[0008] The elastic element also includes a fixing element, which is located on the opposite side of the head, and the side of the fixing element away from the mounting plate is an inclined surface.

[0009] The mounting plate is also provided with an unlocking component, which includes a sliding rod that is slidably connected to the mounting plate and is located in a through hole; a pressing part is fixedly connected to the side of the sliding rod away from the mounting plate, and the pressing part has a second inclined surface that cooperates with the first inclined surface;

[0010] In particular, from the end of the through hole to the center, both inclined surfaces one and two gradually move closer to the mounting plate.

[0011] As a preferred embodiment of this utility model, there are at least two snap-fit ​​components.

[0012] As a preferred embodiment of this utility model, the unlocking component further includes:

[0013] The movable plate is slidably connected to the mounting plate.

[0014] The sliding rod is fixedly connected to the moving plate;

[0015] The drive mechanism is used to drive the moving plate to move.

[0016] As a preferred embodiment of this utility model, the driving mechanism is a screw, and one end of the screw is rotatably connected to the mounting plate;

[0017] The screw is threadedly connected to the moving plate.

[0018] As a preferred embodiment of this utility model, the side of the head away from the mounting plate is an arc surface.

[0019] As a preferred embodiment of this utility model, the buckle assembly includes at least two elastic elements.

[0020] As a preferred embodiment of this utility model, an operating part is fixed at the other end of the screw.

[0021] As a preferred embodiment of this utility model, the movable plate is fixed with a guide rod, and the guide rod is slidably connected to the mounting plate.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: When the main body of the distributed control logic module and the mounting plate are fixed, the head protrudes from the connecting part and locks with the main body of the distributed control logic module to achieve fixation. When it is necessary to remove the main body of the distributed control logic module, push down the sliding rod that is slidably connected to the mounting plate. The sliding rod drives the pressing part that is fixedly connected to it to move. Because the second inclined surface of the pressing part and the first inclined surface of the fixing part cooperate with each other, and both gradually move towards the mounting plate from the end of the through hole to the center, when the pressing part moves, the second inclined surface exerts a pressing effect on the first inclined surface, causing the head of the elastic element to bend towards the center and detach from the main body of the distributed control logic module, thus completing the unlocking. This device uses the inclined surface cooperation principle through the unlocking component, and only a simple sliding operation is required to unlock. Compared with the traditional method of opening the elastic buckles one by one or loosening the screws, the disassembly efficiency is greatly improved. Attached Figure Description

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0033] Example

[0034] Reference Figure 1This embodiment provides a fixing device for a smart distributed control logic module in a hydropower plant, including a distributed control logic module body 1 and a mounting plate 2; the mounting plate 2 is provided with a snap-fit ​​component 3, and the distributed control logic module body 1 is provided with a through hole 4 that cooperates with the snap-fit ​​component 3; the mounting plate 2 can be made of a plastic plate or a metal plate of appropriate thickness to ensure its strength and durability, and the position of the snap-fit ​​component 3 is set according to the through hole 4 on the distributed control logic module body 1, with the position of the through hole 4 corresponding one-to-one with the snap-fit ​​component 3;

[0035] The snap-fit ​​assembly 3 includes: at least one elastic element that is fixedly connected to the mounting plate 2; the elastic element is made of metal or plastic material that can form an elastic plate to ensure that it has good elasticity and strength;

[0036] Reference Figures 2-6 The elastic element includes a head 31 and a connecting part 32. The connecting part 32 is located inside the through hole 4. The head 31 protrudes from the position of the connecting part 32 and is locked with the distributed control logic module body 1. The head 31 is slightly larger than the connecting part 32. The connecting part 32 is firmly fixed to the mounting plate 2 by welding, riveting, or integral molding. When the distributed control logic module body 1 and the mounting plate 2 are fixed, the head 31 protrudes from the position of the connecting part 32 and is locked with the distributed control logic module body 1 to prevent the two from separating.

[0037] The elastic element also includes a fixing element 33, which is located on the opposite side of the head 31. The side of the fixing element 33 away from the mounting plate 2 is a slope 34. The fixing element 33 can be integrally formed with other parts of the elastic element to improve strength.

[0038] The mounting plate 2 is also provided with an unlocking component 5, which includes a sliding rod 51 that is slidably connected to the mounting plate 2. More specifically, a through hole is provided on the mounting plate 2, and the sliding rod 51 slides in the through hole. The cross-section of the sliding rod 51 can be any shape. The sliding rod 51 is located in the through hole 4. A pressing part 52 is fixedly connected to the side of the sliding rod 51 away from the mounting plate 2. The pressing part 52 has a second inclined surface 53 that cooperates with the first inclined surface 34.

[0039] In particular, from the end of the through hole 4 to the center, the first inclined surface 34 and the second inclined surface 53 gradually move closer to the mounting plate 2, and the first inclined surface 34 and the second inclined surface 53 have overlapping parts. More specifically, the first inclined surface 34 and the second inclined surface 53 are preferably parallel. If they are not parallel, large wear may occur during the sliding process.

[0040] The specific process of this device is as follows: When the main body 1 of the distributed control logic module and the mounting plate 2 are fixed, the head 31 protrudes from the position of the connecting part 32 and locks with the main body 1 of the distributed control logic module to achieve the fixation of the two. When it is necessary to remove the main body 1 of the distributed control logic module, push down the sliding rod 51 that is slidably connected on the mounting plate 2. The sliding rod 51 drives the pressing part 52 that is fixedly connected to it to move. Because the second inclined surface 53 of the pressing part 52 and the first inclined surface 34 of the fixing part 33 cooperate with each other, and both gradually move towards the mounting plate 2 from the end of the through hole 4 to the center, when the pressing part 52 moves, the second inclined surface 53 exerts a pressing effect on the first inclined surface 34, causing the head 31 of the elastic element to bend towards the center and detach from the main body 1 of the distributed control logic module, thus completing the unlocking. This device uses the principle of inclined surface cooperation through the unlocking component 5, and can be unlocked with only a simple sliding operation. Compared with the traditional method of opening the elastic buckles one by one or loosening the screws 55, it greatly improves the disassembly efficiency.

[0041] In some embodiments of this utility model, reference is made to Figure 1 There should be at least two snap-fit ​​components 3. The number of snap-fit ​​components 3 should be reasonably determined according to the size and weight of the distributed control logic module body 1. Generally, small distributed control logic module body 1 can be equipped with 2-4 snap-fit ​​components 3, and large distributed control logic module body 1 can be equipped with more than 4. The snap-fit ​​components 3 should be evenly distributed on the mounting plate 2 to ensure the uniformity of fixation. For example, for a rectangular distributed control logic module body 1, one snap-fit ​​component 3 can be set at each of the four corners of the mounting plate 2. Setting at least two snap-fit ​​components 3 can fix the distributed control logic module body 1 from multiple positions. Compared with a single snap-fit ​​component 3, the reliability of fixation is greatly improved. When the distributed control logic module body 1 is subjected to external force, multiple snap-fit ​​components 3 can distribute the force, reduce the load on a single snap-fit ​​component 3, and reduce fixation failure caused by excessive local force.

[0042] In some embodiments of this utility model, reference is made to Figure 3 and Figure 5 Unlocking component 5 also includes:

[0043] Movable plate 54, which is slidably connected to mounting plate 2;

[0044] The sliding rod 51 is fixedly connected to the movable plate 54 by welding or bolts to ensure a firm connection.

[0045] A drive mechanism is used to drive the movable plate 54 to move.

[0046] When it is necessary to unlock the main body 1 of the distributed control logic module, the operating drive mechanism causes the moving plate 54 and the sliding rod 51 to slide downward relative to the mounting plate 2, thereby the squeezing part 52 exerts a squeezing effect on the fixing part 33 of the elastic element to achieve unlocking.

[0047] In some embodiments of this utility model, reference is made to Figure 3 The driving mechanism is a screw 55. One end of the screw 55 is rotatably connected to the mounting plate 2. A bearing seat is set on the mounting plate 2. One end of the screw 55 is installed in the bearing seat through the bearing, so as to realize the rotatable connection with the mounting plate 2 and ensure that the screw 55 rotates flexibly.

[0048] The screw 55 is threadedly connected to the movable plate 54. The movable plate 54 has a threaded hole that matches the screw 55. The thread precision matches the screw 55 to ensure smooth thread engagement between the screw 55 and the movable plate 54. During installation, the screw 55 is passed through the threaded hole of the movable plate 54 and the position is adjusted to ensure a tight connection between the screw 55 and the movable plate 54.

[0049] When the movable plate 54 needs to be driven to perform the unlocking operation, the screw 55 is rotated. Since the screw 55 is threadedly connected to the movable plate 54, as the screw 55 rotates, according to the principle of thread transmission, the movable plate 54 will move along the axial direction of the screw 55. The movable plate 54 drives the sliding rod 51 fixedly connected to it to move synchronously. The pressing part 52 on the sliding rod 51 then exerts a pressing effect on the fixing part 33 of the elastic element, thereby unlocking the main body 1 of the distributed control logic module. When the screw 55 is rotated in the opposite direction, the movable plate 54 will move in the opposite direction, driving the sliding rod 51 to reset. The elastic element returns to its original state under its own elastic force, preparing for the next fixing and unlocking operation.

[0050] The screw 55, as a driving mechanism, has the advantages of compact structure, small space occupation, and compatibility with the structural layout of the entire fixed device. At the same time, compared with other complex driving methods, the screw 55 has lower driving cost and is easy to maintain, which improves the cost performance and practicality of the entire device and greatly enhances the convenience and stability of the unlocking operation of the main body 1 of the distributed control logic module.

[0051] In some embodiments of this utility model, reference is made to Figure 2 and Figure 6 The head 31 has an arc surface 35 on the side away from the mounting plate 2. The radius of the arc surface 35 is designed reasonably according to the size of the through hole 4 on the main body 1 of the distributed control logic module and the structure of the elastic element, so as to ensure that the arc surface 35 can smoothly contact the inner wall of the bottom end of the through hole 4 and produce a suitable squeezing effect during the installation process. After processing, the arc surface 35 is ground and polished to ensure a smooth surface and reduce frictional resistance during the installation process.

[0052] When installing the main body 1 of the distributed control logic module, align the through hole 4 on the main body 1 with the head 31 of the elastic element and press down. When the inner wall of the bottom end of the through hole 4 contacts the arc surface 35 of the head 31, due to the shape characteristics of the arc surface 35, an inward squeezing force will be generated on the head 31. Under the action of this squeezing force, the head 31 of the elastic element bends inward due to its own elasticity, so that the connecting part 32 can pass through the through hole 4 smoothly. As the main body 1 of the distributed control logic module continues to be pressed down, the head 31 completely passes through the through hole 4 and returns to its original shape, realizing the locking and fixing with the main body 1 of the distributed control logic module. During the installation process, the contact method between the arc surface 35 and the inner wall of the through hole 4 allows the head 31 to automatically adapt to the through hole 4 and pass through smoothly without the need for the operator to deliberately adjust the position or apply additional force, which greatly simplifies the installation operation process and improves the installation efficiency.

[0053] It should be noted that, since the elastic element will move closer to the pressing part 52 and the sliding rod 51 during the inward bending process, in order to prevent the pressing part 52 and the sliding rod 51 from interfering with the bending of the elastic element, when the main body 1 of the distributed control logic module and the mounting plate 2 are in a fixed state, the elastic element is spaced apart from the pressing part 52 and the sliding rod 51.

[0054] In some embodiments of this utility model, reference is made to Figure 2 The latching assembly 3 includes at least two elastic elements, which are arranged in a circular array around the sliding rod 51 to ensure that the elastic elements move in unison. By setting at least two elastic elements as the latching assembly 3, the main body 1 of the distributed control logic module is fixed from multiple directions. Compared with fixing with a single elastic element, the stability and reliability of the fixation are greatly improved. Multiple elastic elements can evenly distribute the external force on the main body 1 of the distributed control logic module, avoiding fixation failure due to excessive local force. During disassembly, multiple elastic elements can be unlocked simultaneously by a unified unlocking assembly 5, which greatly improves the disassembly efficiency.

[0055] In some embodiments of this utility model, reference is made to Figure 3 The other end of the screw 55 is fixed with an operating part 56. The operating part 56 can be designed and selected according to actual usage needs and operating habits. If it is for manual operation, the operating part 56 can be designed as a round handle. The handle is made of engineering plastic or metal and the surface is treated with anti-slip treatment, such as setting anti-slip texture or wrapping with anti-slip rubber sleeve. The handle is fixed to the other end of the screw 55 by welding or bolt connection. If it is considered that auxiliary tools may be needed for operation, the operating part 56 can be designed as a polygonal interface, such as a hexagonal interface, to facilitate use with tools such as wrenches. When installing the operating part 56, ensure that its connection with the screw 55 is firm and that it will not loosen or fall off during operation.

[0056] In some embodiments of this utility model, reference is made to Figure 4 The movable plate 54 is fixed with a guide rod 57, which is slidably connected to the mounting plate 2. More specifically, a groove is opened at the corresponding position of the mounting plate 2 for the guide rod 57 to extend into. There are at least two guide rods 57, which serve to prevent the movable plate 54 from rotating.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
