Description

Technical Field

[0001] This invention relates to the field of nuclear power engineering construction technology, and more specifically, to a concrete vibration device for substations. Background Technology

[0002] In nuclear power engineering construction, the construction of substations is of paramount importance. The concrete structures in substations, such as foundations, cable trenches, and equipment bases, need to meet extremely high quality standards to ensure that they can withstand various complex working conditions during long-term operation, including earthquakes, equipment vibrations, and the influence of environmental factors. Among these, concrete vibration is a key step in the concrete construction process. Its purpose is to expel air from the concrete and allow the aggregate and cement paste to mix thoroughly, thereby improving the density, strength, and durability of the concrete.

[0003] In the foundation pouring construction of substations and large industrial equipment, in order to ensure structural strength and smooth equipment installation, the foundation is usually designed with a dense steel reinforcement cage and a large number of high-precision anchor bolts and other embedded parts.

[0004] In existing technologies, concrete vibration and air removal mainly rely on workers using handheld high-frequency vibrators. However, this purely manual operation mode has significant drawbacks: First, the vibrating equipment is heavy and the working environment is limited, making it difficult for operators to precisely control the placement and lowering posture of the vibrator within complex steel reinforcement meshes; second, during vibration, the high-speed vibrating rod is highly susceptible to contacting and impacting adjacent embedded parts and steel reinforcement. This uncontrollable collision not only damages the load-bearing structure of the steel reinforcement cage but also causes irreversible millimeter-level or even centimeter-level displacement of high-precision anchor bolts. Once the planar coordinates or verticality of the anchor bolts deviate, it will directly lead to the inaccurate positioning of subsequent large electrical equipment, or even rework, greatly increasing construction costs and safety hazards.

[0005] Therefore, a concrete vibration device for substations is proposed. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of this invention is to provide a substation concrete vibration device that can reduce damage to embedded parts during the vibration process.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A substation concrete vibrating device includes a connecting rod, with a vibrating assembly fixedly installed at the end of the connecting rod; wherein the vibrating assembly includes a sealed and hollow shell, a motor, and an eccentric block;

[0009] It also includes a limiting sleeve with openings at both ends, with through holes evenly distributed on the surface of the limiting sleeve, and a buffer component provided on the inner wall surface of the limiting sleeve;

[0010] The buffer assembly includes an outer ring plate fixedly installed on the inner wall of the limiting sleeve, and an annular groove is provided on the inner ring side of the outer ring plate;

[0011] An inner ring plate corresponding to the outer ring plate is fixedly installed on the side wall of the outer shell, and the inner ring plate is movably inserted into the annular groove.

[0012] An annular mounting groove is provided on the top wall of the annular groove, and a circular ring is slidably inserted into the annular mounting groove along the vertical direction; the circular ring is concentrically positioned outside the inner annular plate.

[0013] The inner diameter of the ring sleeve gradually increases from top to bottom, and an elastic block is pressed between the top surface of the ring sleeve and the top wall of the annular mounting groove.

[0014] An auxiliary force relief mechanism that cooperates with the inner circular plate is provided in the annular groove;

[0015] Furthermore, a buffer spring is installed at the bottom of the limiting sleeve;

[0016] The outer wall of the limiting sleeve is provided with scrapers that correspond one-to-one with the through holes, and the limiting sleeve is provided with a drive mechanism for driving the scrapers to move.

[0017] Furthermore, a first sleeve and a second sleeve are fixedly provided at the top and bottom ends of the outer wall of the limiting sleeve, respectively. The adjacent ends of the first sleeve and the second sleeve are open and they are coaxially arranged.

[0018] An installation rod is slidably inserted between the open ends of the first sleeve and the second sleeve. The axis of the installation rod is parallel to the central axis of the limiting sleeve, and the scraper is fixedly installed on the side wall of the installation rod. Both the installation rod and the scraper are slidably fitted against the outer wall of the limiting sleeve.

[0019] Furthermore, the driving mechanism includes an active magnet that is fixedly embedded in the top wall of the annular sleeve;

[0020] The mounting rod is fitted with a driven magnet that corresponds to the position of the active magnet, and the active magnet and the driven magnet attract each other.

[0021] Furthermore, an anti-clogging filter screen is fixedly installed inside the through hole; and the sidewall of the through hole has a guide slope structure that slopes from the outside to the inside, with an inclination angle of 30° to 45°.

[0022] Furthermore, a hollow structure mounting bracket is fixedly installed at the bottom of the limiting sleeve, and a buffer spring is fixedly installed at the bottom of the mounting bracket. An elastic bellows with both ends sealed is sleeved on the outside of the buffer spring, and the bottom end of the elastic bellows is spherical.

[0023] Furthermore, the auxiliary pressure relief mechanism includes an elastic tube fixedly installed between the annular groove and the inner annular plate, and the ratio of the vertical internal height of the annular groove to the vertical thickness of the inner annular plate is 1.5-2.

[0024] Furthermore, elastic tubes are vertically fixedly installed on both the top and bottom walls of the inner annular plate, with the top and bottom ends of the two elastic tubes respectively fixedly connected to the top and bottom walls of the annular groove.

[0025] Furthermore, a number of metal heat-conducting bumps are uniformly fixed on the outer surface of the shell, and the metal heat-conducting bumps have a hemispherical structure.

[0026] Furthermore, several flexible aerodynamic baffles are uniformly fixedly installed on the inner wall of the limiting sleeve. The flexible aerodynamic baffles are made of high-molecular elastic material.

[0027] One end of the flexible spoiler is fixed to the inner wall of the limiting sleeve, while the other end extends toward the outer shell and maintains a small gap with the outer wall of the outer shell.

[0028] Furthermore, the flexible spoilers are staggered between adjacent through holes.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] (1) This scheme uses a mechanical transmission structure formed by a limiting sleeve, an inner ring plate and a ring sleeve with an inclined surface to convert the radial rigid impact force generated by the vibrating component into longitudinal elastic potential energy, thereby preventing the displacement of high-precision pre-embedded bolts or damage to the steel reinforcement structure caused by collision during the vibration process, and ensuring the geometric accuracy and structural safety of the substation foundation construction.

[0031] (2) This scheme utilizes non-contact magnetic coupling between the active magnet and the driven magnet to convert the vertical displacement of the internal components into the reciprocating motion of the external scraper. This design can automatically remove large particles of gravel and mud from the surface of the through hole of the limiting sleeve without the need for an additional power source, preventing the hole from becoming blocked, ensuring full contact between the flowing concrete and the vibrating components, and guaranteeing the compaction of the deep concrete.

[0032] (3) This solution uses the metal heat-conducting protrusions on the outer shell and the flexible turbulence-disrupting blades on the inner side of the limiting sleeve to enable the device to achieve forced physical stirring and disturbance of the surrounding slurry during vibration. This dynamic heat exchange mechanism destroys the thermal boundary layer and accelerates the circulation and discharge of the slurry that has absorbed the heat of the motor through the through hole, thereby solving the heat dissipation problem of the vibrating assembly in the closed limiting space and preventing the motor from overheating and being damaged.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] Please see Figures 1 to 7 A substation concrete vibration device includes a connecting rod 1, with a vibration assembly fixedly installed at the end of the connecting rod 1; wherein the vibration assembly includes a sealed and hollow shell 2, a motor 3, and an eccentric block 4;

[0045] Motor 3 is fixedly installed inside housing 2 by a shock-absorbing bracket to ensure that housing 2 can vibrate freely;

[0046] Eccentric block 4 is installed on the output shaft of motor 3. When motor 3 is working, eccentric block 4 rotates at high speed with the shaft, generating periodic centrifugal force. This centrifugal force is transmitted to the entire vibration assembly through the housing of motor 3, forcing the outer shell 2 and internal structure to generate high-frequency vibration, thereby achieving the vibration and compaction of concrete. The vibration assembly is existing technology and will not be described in detail here.

[0047] It also includes a limiting sleeve 5 with openings at both ends. The surface of the limiting sleeve 5 is evenly provided with through holes 6, so that the vibrating component can directly contact the concrete. The inner wall surface of the limiting sleeve 5 is provided with a buffer component.

[0048] The buffer assembly includes an outer ring plate 7 fixedly installed on the inner wall of the limiting sleeve 5, and an annular groove 8 is provided on the inner ring side of the outer ring plate 7;

[0049] An inner ring plate 9 corresponding to the outer ring plate 7 is fixedly installed on the side wall of the outer shell 2, and the inner ring plate 9 is movably inserted into the annular groove 8.

[0050] An annular mounting groove is provided on the top wall of the annular groove 8, and a circular ring sleeve 10 is slidably inserted into the annular mounting groove along the vertical direction; the circular ring sleeve 10 is concentrically positioned outside the inner circular ring plate 9.

[0051] The inner diameter of the ring sleeve 10 gradually increases from top to bottom to form a mating inclined surface, that is, the inner wall of the ring sleeve 10 is an inclined surface, and an elastic block 11 is pressed between the top surface of the ring sleeve 10 and the top wall of the annular mounting groove; under the normal elastic force of the elastic block 11, the bottom end of the ring sleeve 10 extends out of the annular mounting groove and is aligned with the inner ring plate 9.

[0052] An auxiliary force relief mechanism that cooperates with the inner annular plate 9 is provided in the annular groove 8;

[0053] Furthermore, a buffer spring 12 is installed at the bottom of the limiting sleeve 5;

[0054] The outer wall of the limiting sleeve 5 is provided with a scraper 13 that corresponds one-to-one with the through hole 6, and the limiting sleeve 5 is provided with a drive mechanism for driving the scraper 13 to move.

[0055] Construction workers lower the vibratory assembly, which is fitted with a limiting sleeve 5, through the gaps in the dense steel reinforcement cage into the concrete. When the vibratory assembly is lowered to the bottom or touches an obstacle at the bottom, the buffer spring 12 at the bottom is compressed to prevent the end of the vibratory assembly from rigidly colliding with the bottom steel reinforcement or high-precision pre-embedded bolts.

[0056] After the limiting sleeve 5 is submerged in the concrete, the flowing concrete enters the interior of the limiting sleeve 5 through the surface through hole 6 and makes full contact with the outer shell 2 of the vibrating assembly. After the motor 3 is started, the eccentric block 4 rotates at high speed with the output shaft to generate periodic centrifugal force. This centrifugal force forces the outer shell 2 of the vibrating assembly to generate high-frequency vibration, thereby directly transferring the vibration energy to the concrete inside the sleeve, achieving the functions of air venting and compaction.

[0057] In actual operation, the limiting sleeve 5 remains relatively stationary due to the resistance of the external concrete enclosure.

[0058] When the side wall of the limiting sleeve 5 accidentally comes into contact with the steel reinforcement frame or the pre-embedded bolt during operation, the high-frequency impact force generated by the outer shell 2 of the vibrating component will be preferentially transmitted to the inner ring plate 9. The inner ring plate 9 will then shift in the horizontal direction and squeeze the outer ring sleeve 10.

[0059] Because the inner wall of the annular sleeve 10 is designed as a gradually widening inclined structure from top to bottom, when it is subjected to the radial horizontal thrust of the inner annular plate 9, the thrust undergoes mechanical decomposition along the inclined surface. The resulting vertical upward component forces the annular sleeve 10 to slide upward along the annular mounting groove, simultaneously and forcefully compressing the elastic block 11 at the top. This mechanical transmission process converts the destructive radial rigid impact force into longitudinal elastic potential energy, thereby improving the flexible buffer limit of the device and preventing damage to the reinforcing steel structure or displacement of the embedded bolts, thus protecting the embedded parts.

[0060] At the same time, the scraper 13 is driven by the drive mechanism to move on the surface of the limiting sleeve 5. The scraper 13 scrapes and transfers the large particles of gravel attached to the surface of the through hole 6, thereby ensuring that the concrete can pass through the through hole 6 and contact the vibrating component.

[0061] like Figure 1 As shown, the top and bottom ends of the outer wall of the limiting sleeve 5 are respectively fixed with a first sleeve 14 and a second sleeve 15. The adjacent ends of the first sleeve 14 and the second sleeve 15 are open and they are coaxially arranged.

[0062] An installation rod 16 is slidably inserted between the open ends of the first sleeve 14 and the second sleeve 15. The axis of the installation rod 16 is parallel to the central axis of the limiting sleeve 5, and the scraper 13 is fixedly installed on the side wall of the installation rod 16. The installation rod 16 and the scraper 13 are both slidably attached to the outer wall of the limiting sleeve 5.

[0063] like Figure 1 As shown, the limiting sleeve 5 is made of non-magnetic material; the driving mechanism includes an active magnet 17 fixedly embedded in the top wall of the annular sleeve 10;

[0064] The mounting rod 16 is fitted with a driven magnet 18 corresponding to the position of the active magnet 17, and the active magnet 17 and the driven magnet 18 attract each other. The active magnet 17 and the driven magnet 18 are magnetically attracted through the side wall of the limiting sleeve 5 to form a non-contact magnetic coupling linkage mechanism.

[0065] In actual construction operations, when the inner annular sleeve 10 is squeezed by radial impact force and undergoes vertical displacement, due to the strong magnetic attraction between the active magnet 17 and the driven magnet 18, the outer mounting rod 16 overcomes the frictional force and slides synchronously up and down within the first sleeve 14 and the second sleeve 15.

[0066] This allows the scraper 13, fixed on the mounting rod 16, to reciprocate and scrape the outer surface of the limiting sleeve 5, thereby automatically removing and cleaning large particles of gravel and semi-solidified mud adhering to the surface of the through hole 6, preventing the hole from becoming blocked, and thus ensuring the efficient entry and exit of concrete slurry and compaction.

[0067] like Figure 1 As shown, an anti-clogging filter 19 is fixedly installed inside the through hole 6. The mesh diameter of the anti-clogging filter 19 is smaller than the minimum particle size of the concrete aggregate of the substation foundation. The side wall of the through hole 6 has a guide slope structure that slopes from the outside to the inside, with an inclination angle of 30° to 45°, which is used to guide the cement slurry to flow in and block large particles of gravel.

[0068] like Figure 1 As shown, a hollow structure mounting bracket 20 is fixedly installed at the bottom end of the limiting sleeve 5, and a buffer spring 12 is fixedly installed at the bottom end of the mounting bracket 20. An elastic corrugated tube 21 with both ends sealed is sleeved on the outside of the buffer spring 12, and the bottom end of the elastic corrugated tube 21 is spherical.

[0069] The elastic corrugated pipe 21 provides isolation, preventing gravel from jamming the buffer spring 12. At the same time, when placing the vibrating assembly between complex steel meshes, the spherical surface at the bottom of the elastic corrugated pipe 21 provides smooth physical guidance, avoiding the end from being rigidly hooked onto the steel bars or anchor bolts.

[0070] like Figure 1 As shown, the auxiliary pressure relief mechanism includes an elastic tube 22 fixedly installed between the annular groove 8 and the inner annular plate 9, and the ratio of the vertical internal height of the annular groove 8 to the vertical thickness of the inner annular plate 9 is 1.5-2, which can prevent the inner annular plate 9 from getting stuck and ensure that the inner annular plate 9 can swing normally in the annular groove 8.

[0071] like Figure 1As shown, elastic tubes 22 are vertically fixedly installed on the top and bottom walls of the inner ring plate 9. The top and bottom ends of the two elastic tubes 22 are fixedly connected to the top and bottom walls of the annular groove 8, respectively, so that the interior of the annular groove 8 forms a closed, movable, flexible cavity. When the outer shell 2 vibrates at high frequency, the elastic tubes 22 deform accordingly to prevent external cement mortar from entering the annular groove 8 and causing the inner ring plate 9 to jam.

[0072] As the inner annular plate 9 moves horizontally, it forces the elastic tube 22 within the annular groove 8 to undergo compression deformation to absorb the excitation energy. This flexible buffering mechanism cuts off the transmission path of the rigid impact force to the outside of the limiting sleeve 5.

[0073] like Figure 1 As shown, a number of metal heat-conducting protrusions 23 are uniformly fixed on the outer surface of the outer shell 2. The metal heat-conducting protrusions 23 have a hemispherical structure and are used to increase the contact area between the outer shell 2 and the external medium, thereby improving the heat dissipation efficiency of the vibrating assembly.

[0074] In high-frequency vibration operation, the hemispherical metal heat-conducting protrusion 23 not only expands the heat exchange area between the outer shell 2 and the external concrete slurry, but also generates strong microscopic disturbance and convection to the surrounding slurry during vibration; in addition, the hemispherical structure has extremely high structural strength, which can resist shear fatigue caused by high-frequency excitation, and improves the heat dissipation effect of the internal motor 3 while ensuring structural stability.

[0075] like Figure 1 As shown, several flexible turbulence-disrupting paddles 24 are uniformly fixedly installed on the inner wall of the limiting sleeve 5. The flexible turbulence-disrupting paddles 24 are made of high-molecular elastic material.

[0076] One end of the flexible spoiler 24 is fixed to the inner wall of the limiting sleeve 5, and the other end extends toward the outer shell 2, maintaining a small gap with the outer wall of the outer shell 2.

[0077] Flexible deflector blades 24 are staggered between adjacent through holes 6;

[0078] When the outer casing 2 generates high-frequency vibration, the outer wall of the outer casing 2 periodically beats and squeezes the flexible baffle 24 at high frequency, forcing the flexible baffle 24 to generate high-frequency elastic deformation and rebound; using the mechanical beating force generated by the high-frequency deformation of the flexible baffle 24, the cement slurry inside the limiting sleeve 5 is forcibly stirred and disturbed, destroying the thermal boundary layer, thereby accelerating the discharge of the cement slurry that has absorbed the heat of the motor 3 from the through hole 6, realizing dynamic heat exchange and cooling of the internal motor 3, and playing a role in protecting the motor 3.

[0079] Instructions for use: Construction workers lower the vibrating assembly, which is fitted with a limiting sleeve 5, through the gaps in the dense steel reinforcement cage into the concrete. When the vibrating assembly reaches the bottom or touches an obstacle at the bottom, the buffer spring 12 at the bottom is compressed to prevent the end of the vibrating assembly from rigidly colliding with the bottom steel reinforcement or high-precision pre-embedded bolts.

[0080] After the limiting sleeve 5 is submerged in the concrete, the flowing concrete enters the interior of the limiting sleeve 5 through the surface through hole 6 and makes full contact with the outer shell 2 of the vibrating assembly. After the motor 3 is started, the eccentric block 4 rotates at high speed with the output shaft to generate periodic centrifugal force. This centrifugal force forces the vibrating shell 2 to generate high-frequency vibration, thereby directly transferring the vibration energy to the concrete inside the sleeve, achieving the functions of air venting and compaction.

[0081] In actual operation, the limiting sleeve 5 remains relatively stationary due to the resistance of the external concrete enclosure.

[0082] When the side wall of the limiting sleeve 5 accidentally comes into contact with the steel reinforcement frame or the pre-embedded bolt during the operation, the high-frequency impact force generated by the vibrating shell 2 will be preferentially transmitted to the inner ring plate 9. The inner ring plate 9 will then shift in the horizontal direction and squeeze the outer ring sleeve 10.

[0083] Because the inner wall of the annular sleeve 10 is designed as a gradually widening inclined structure from top to bottom, when it is subjected to the radial horizontal thrust of the inner annular plate 9, the thrust undergoes mechanical decomposition along the inclined surface. The resulting vertical upward component forces the annular sleeve 10 to slide upward along the annular mounting groove, simultaneously and forcefully compressing the elastic block 11 at the top. This mechanical transmission process converts the destructive radial rigid impact force into longitudinal elastic potential energy, thereby improving the flexible buffer limit of the device and preventing damage to the reinforcing steel structure or displacement of the embedded bolts, thus protecting the embedded parts.

[0084] At the same time, the scraper 13 is driven by the drive mechanism to move on the surface of the limiting sleeve 5. The scraper 13 scrapes and transfers the large particles of gravel attached to the surface of the through hole 6, thereby ensuring that the concrete can pass through the through hole 6 and contact the vibrating component.

[0085] In actual construction operations, when the inner annular sleeve 10 is squeezed by radial impact force and undergoes vertical displacement, due to the strong magnetic attraction between the active magnet 17 and the driven magnet 18, the outer mounting rod 16 overcomes the frictional force and slides synchronously up and down within the first sleeve 14 and the second sleeve 15.

[0086] This allows the scraper 13, fixed on the mounting rod 16, to reciprocate and scrape the outer surface of the limiting sleeve 5, thereby automatically removing and cleaning large particles of gravel and semi-solidified mud adhering to the surface of the through hole 6, preventing the hole from becoming blocked, and thus ensuring the efficient entry and exit of concrete slurry and compaction.

[0087] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
