Description

Technical Field

[0001] This utility model belongs to the field of power civil engineering technology, and more specifically, it relates to a foundation bolt protection and sealing device. Background Technology

[0002] In the field of power civil engineering, foundation bolts are key load-bearing components connecting core power equipment (such as transformers, circuit breakers, and transmission tower legs) to the concrete foundation. The stability and reliability of their connection directly determine the long-term safety and stability of power facilities, and are an important structural foundation for ensuring the normal transmission and distribution of power systems. Currently, most foundation bolts used in engineering adopt a direct through-hole and rigid fixing assembly method. The bolts pass directly through pre-drilled bolt holes in the civil engineering base of the power equipment, and then the bolts' own tightening force rigidly connects the civil engineering base to the concrete foundation, ultimately completing the fixation of the equipment to the foundation.

[0003] Existing application number CN201921109526.8 discloses a novel bolt anti-loosening sealing assembly, comprising a protective cover and a protective seat. The protective seat has a central cavity for inserting a bolt and a mounting hole at the bottom of the central cavity. After the bolt shank passes through the mounting hole, it is secured to the protective seat with a nut. The protective cover is fastened onto the protective seat to seal and axially limit the bolt. Using the above technical solution, this utility model uses a tight-fitting method between the protective seat and the protective cover to seal and prevent loosening of bolts and other fasteners. The sealing ring and the protruding arc portion of the protective cover ensure a double seal for both the bolt head and shank. After the protective cover and the protective seat are fastened together, they compress the bolt head, increasing the axial compressive force while limiting the radial rotation of the bolt through the limiting groove. The combination of these two factors effectively prevents the bolt from loosening.

[0004] Based on the above, after the assembly and fastening of the civil engineering foundation of the power equipment is completed, the bolt body, especially the exposed bolt head, is mostly directly exposed to the surface of the civil engineering foundation, completely exposed to the complex outdoor environment. Since power projects are mostly deployed outdoors, these unprotected foundation bolts need to withstand wind, rain, snow, and ultraviolet radiation for a long time. They may also come into contact with industrial dust and corrosive gases such as sulfides and nitrogen oxides around the substation, which are prone to electrochemical corrosion, shortening their service life and increasing maintenance costs. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a foundation bolt protective sealing device. This device solves the problem that after the assembly and tightening of the civil engineering foundation for power equipment, the bolt body, especially the exposed bolt head, is mostly directly exposed to the surface of the civil engineering foundation, completely exposed to the complex outdoor environment. Since power projects are mostly deployed outdoors, these unprotected foundation bolts must withstand long-term wind, rain, snow, and ultraviolet radiation. They may also come into contact with industrial dust and corrosive gases such as sulfides and nitrogen oxides around substations, easily leading to electrochemical corrosion, shortening their service life and increasing maintenance costs.

[0006] The purpose and effectiveness of this utility model's basic bolt protective sealing device are achieved through the following specific technical means:

[0007] A basic bolt protective sealing device includes a power base, sealing grooves, bolt holes, basic bolts, sealing covers, sealing components, and a drying component. Multiple sets of sealing grooves are provided, and these multiple sets of sealing grooves are formed inside the power base. Multiple sets of bolt holes are provided, and these multiple sets of bolt holes are formed inside the power base. Multiple sets of sealing covers are provided, and these multiple sets of sealing covers are respectively engaged with the upper parts of multiple sets of sealing grooves. The sealing component is disposed inside the sealing groove. The drying component is disposed inside the sealing cover.

[0008] Furthermore, the sealing assembly includes: buttons and elastic elements, wherein multiple sets of buttons are provided, and every two sets of buttons are slidably connected to each other inside a sealing cover; multiple sets of elastic elements are provided, and every two sets of elastic elements are fixedly installed on the back of a set of buttons.

[0009] Furthermore, the sealing assembly also includes: a limiting hook and a limiting hole. The limiting hook is provided in multiple sets, and the multiple sets of the limiting hook are fixedly installed at the bottom of multiple sets of buttons. The limiting hole is provided in multiple sets, and every two sets of the limiting holes are opened on both sides inside a sealing groove.

[0010] Furthermore, the sealing assembly also includes: a transmission plate and a transmission rod, wherein multiple sets of transmission plates are provided, and every two sets of transmission plates are slidably connected to each other inside a set of sealing covers; multiple sets of transmission rods are provided, one end of each set of transmission rods is hinged to the outside of multiple sets of buttons, and the other end of each set of transmission rods is hinged to the outside of multiple sets of transmission plates.

[0011] Furthermore, the sealing assembly also includes: a limiting groove and a limiting block.

[0013] Furthermore, the drying assembly also includes: observation windows and filters; multiple sets of observation windows are provided, and multiple sets of observation windows are fixedly installed on the top of multiple drying cylinders; multiple sets of filters are provided, and multiple sets of filters are fixedly installed on the bottom of multiple drying cylinders.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, this utility model has a sealing component. By pressing the buttons on both sides of the sealing cover, the limiting hooks are driven to move closer and compress the elastic element, and the sealing cover is inserted into the sealing groove. After releasing the button, the elastic element pushes the limiting hook into the limiting hole to complete the sealing cover fixing. At the same time, the movement of the button drives the transmission plate to slide through the transmission rod. After releasing the button, the transmission plate retracts and causes the limiting block to be inserted into the bolt limiting groove, which not only achieves the sealing protection of the bolt, but also prevents the bolt from loosening due to vibration and improves the connection stability.

[0016] Secondly, this utility model has a drying component. By placing a color-changing silica gel desiccant in the drying cylinder inside the sealed cover, the filter screen intercepts the desiccant and ensures that the drying cylinder is connected to the sealing groove. When water vapor seeps in, the desiccant absorbs moisture and changes color. Maintenance personnel can intuitively judge the sealing status and desiccant status through the observation window, and can handle it in time without disassembly, reducing the difficulty of maintenance.

[0017] This utility model has the advantages of sealing and drying, preventing loosening, and convenient maintenance. It also has the functions of sealing and preventing loosening as well as moisture monitoring. It effectively isolates the bolts from the corrosion of harsh outdoor environments, delays rusting, extends the service life of the bolts, reduces maintenance costs, and ensures the safe and stable operation of power facilities.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides a basic bolt protection and sealing device, including an electric base 1, a sealing groove 2, bolt holes 3, a basic bolt 4, a sealing cover 5, and a sealing assembly. The sealing groove 2 is provided in multiple sets, and the multiple sets of sealing grooves 2 are opened inside the electric base 1; the bolt holes 3 are provided in multiple sets, and the multiple sets of bolt holes 3 are opened inside the electric base 1; the sealing cover 5 is provided in multiple sets, and the multiple sets of sealing covers 5 are respectively snapped onto the upper part of the multiple sets of sealing grooves 2; the sealing assembly is disposed inside the sealing groove 2.

[0029] The sealing assembly includes: a button 501 and an elastic element 5012. Multiple sets of buttons 501 are provided, and every two sets of buttons 501 are slidably connected to each other inside a sealing cover 5. Multiple sets of elastic elements 5012 are provided, and every two sets of elastic elements 5012 are fixedly installed on the back of a set of buttons 501.

[0030] The sealing assembly also includes: a limit hook 5011 and a limit hole 201. Multiple sets of limit hooks 5011 are provided, and multiple sets of limit hooks 5011 are fixedly installed at the bottom of multiple sets of buttons 501. Multiple sets of limit holes 201 are provided, and every two sets of limit holes 201 are opened on both sides inside a sealing groove 2.

[0031] The sealing assembly also includes: a transmission plate 502 and a transmission rod 503. Multiple sets of transmission plates 502 are provided, and every two sets of transmission plates 502 are slidably connected to each other inside a set of sealing covers 5. Multiple sets of transmission rods 503 are provided, with one end of each set of transmission rods 503 hinged to the outside of multiple sets of buttons 501, and the other end of each set of transmission rods 503 hinged to the outside of multiple sets of transmission plates 502.

[0032] The sealing assembly also includes: a limiting groove 401 and a limiting block 5021. The limiting groove 401 is provided in multiple sets, and the multiple sets of limiting grooves 401 are opened on the outside of multiple sets of base bolts 4. The limiting block 5021 is provided in multiple sets, and the multiple sets of limiting blocks 5021 are fixedly installed at the bottom of multiple sets of transmission plates 502.

[0033] The specific usage and function of this embodiment are as follows:

[0034] When fixing and assembling the power base 1, first pass the foundation bolt 4 through the bolt hole 3 and tighten it. The bottom of the nut of the foundation bolt 4 is pre-installed with a sealing washer, which can initially seal the gap between the bolt hole 3 and the foundation bolt 4, laying the foundation for subsequent protection.

[0035] When it is necessary to fully seal and protect the foundation bolt 4, the operation steps are as follows: First, press the buttons 501 on both sides of the sealing cover 5. The buttons 501 will simultaneously drive the two sets of limit hooks 5011 to move closer to each other and compress the elastic element 5012 on their backs. Then, align the sealing cover 5 with the sealing groove 2 and insert it until the limit hooks 5011 are precisely aligned with the limit holes 201 in the sealing groove 2. At this time, release the buttons 501. The elastic element 5012 will release its elastic potential energy and push the buttons 501 to reset, so that the limit hooks 5011 can be stably hooked into the limit holes 201, thus completing the limiting and fixing of the sealing cover 5 and the sealing groove 2.

[0036] During this process, the movement of button 501 will also cause the hinged transmission rod 503 to swing synchronously. The transmission rod 503 further drives the transmission plate 502, which is hinged to it, to slide inside the sealing cover 5. When button 501 is pressed, the transmission plate 502 expands outward, causing the limiting block 5021 at its bottom to move away from the base bolt 4, thus avoiding interference with the installation of the sealing cover 5. After button 501 is released, the transmission plate 502 retracts inward as button 501 resets, so that the limiting block 5021 is precisely engaged in the limiting groove 401 on the outside of the base bolt 4, thereby forming a radial limit on the base bolt 4, effectively preventing it from loosening due to factors such as vibration of power equipment operation and outdoor environmental disturbance, and further ensuring connection stability.

[0037] Example 2:

[0038] Based on Example 1, such as Figures 1 to 5 As shown, it also includes a drying component, which is disposed inside the sealing cover 5.

[0039] The drying assembly includes a drying cylinder 6, which is provided in multiple sets, and the multiple sets of drying cylinders 6 are fixedly installed inside the multiple sets of sealing covers 5.

[0040] The drying assembly also includes: observation window 601 and filter screen 602. Multiple sets of observation windows 601 are provided and fixedly installed on the top of multiple drying cylinders 6; multiple sets of filter screens 602 are provided and fixedly installed on the bottom of multiple drying cylinders 6.

[0041] The specific usage and function of this embodiment are as follows:

[0042] The drying cylinder 6 is pre-filled with color-changing silica gel desiccant. The filter screen 602 fixed at the bottom of the cylinder can intercept desiccant particles to prevent them from falling into the sealing groove 2 and affecting the operation of the bolts. On the other hand, it can form a ventilation channel to keep the interior of the drying cylinder 6 connected to the interior space of the sealing groove 2.

[0043] When the sealing structure fails due to aging or wear, external moisture will seep into the sealing groove 2. At this time, the color-changing silica gel desiccant in the drying cylinder 6 will absorb the moisture through the filter screen 602, thus drying the internal environment of the sealing groove 2 and delaying the moisture corrosion of the foundation bolts 4. Simultaneously, the desiccant will undergo a noticeable color change after absorbing moisture, which can be directly observed through the observation window 601 on the top of the drying cylinder 6. Maintenance personnel can determine whether the seal has failed and the status of the desiccant without disassembling the sealing cover 5, facilitating timely seal repair or desiccant replacement.
