Technical Field
[0001] The present invention relates to the technical field of distribution cabinet fixing, and particularly relates to an installation and fixing mechanism for a distribution cabinet. Background Art
[0002] A distribution cabinet is a metal cabinet integrating various electrical components, used for receiving, distributing, and controlling electric energy, while protecting circuits and equipment from faults such as overload and short circuit. Conventional distribution cabinets are directly installed and fixed on a horizontal ground, suitable for the vast majority of areas without earthquakes.
[0003] During an earthquake, the ground undergoes irregular tilting and vibration. Among them, tilting with different levels will affect the internal components of the distribution cabinet. Conventionally, for example, dampers will play a certain degree of shock absorption role, but they cannot avoid the tilting of the distribution cabinet at different angles.
[0004] Therefore, there is an urgent need for an installation and fixing mechanism that can minimize the angular tilt of the distribution cabinet in all directions. Summary of the Invention

[0006] The present invention is realized through the following technical solutions: An installation and fixing mechanism for a distribution cabinet includes a top plate located at the bottom of the distribution cabinet. The top surface of the top plate is inlaid with an upward-opening and spiral-shaped water-cooled heat dissipation component. The water-cooled heat dissipation component includes a water-cooled pipe fixed in a spiral groove at the top of the top plate. Heat conduction fins b and heat conduction fins a are respectively arranged on the inner and outer sides of the water-cooled pipe. The heat conduction fins b and heat conduction fins a meet at the center of the top plate and a circular heat conduction disk is fixed at the meeting point. A hollow universal ball cabin is fixed at the bottom of the top plate and the universal ball cabin is installed in a support ball groove of a lower main support base. A number of support balls tangent to the universal ball cabin are evenly arranged at the bottom of the main support base, and a number of limit balls tangent to the universal ball cabin are evenly arranged at the top of the main support base. The upper end of the universal ball cabin protrudes outside the main support base but the ball center is located inside the main support base. A number of springs are evenly arranged around the universal ball cabin on the main support base. The main support base is fixed on a lower bottom plate. A number of pull rod pistons are evenly arranged in a circle outside the main support base. The pull rod pistons are respectively movably connected to the bottom plate and the top plate through a lower piston rod and an upper piston rod.
[0007] Furthermore, corner seats are installed at the four corners of the top of the top plate. Air inlets are arranged on both sides of the front end face of the top plate, and top plate cooling fans are nested and installed on both sides corresponding to the rear end face. A heat dissipation groove running through the front and rear of the top plate is arranged between the air inlets and the top plate cooling fans.

[0008] Further, one end of the water-cooling pipe is connected downward and communicated with the water outlet pipe, and the other end passes through the bottom of the water-cooling heat dissipation assembly and is communicated with the water inlet pipe; The water outlet pipe is connected to the water tank below the top plate, the water inlet pipe is communicated with the water pump on the water tank, and a heat dissipation fan is arranged on the side of the water tank.
[0009] Further, a spherical damping block is arranged in the universal ball cabin, and the damping block is suspended at the central setting at the bottom of the top plate through a rope, and damping liquid is filled in the universal ball cabin.
[0010] Further, the support ball is located in the ball groove at the bottom of the main support base and the two are in clearance fit, and an oil injection groove hole that is communicated with the outside and inclined upward is arranged on the groove wall of each ball groove; The center of the limiting ball is lower than the upper end surface of the main support base and higher than the center height of the universal ball cabin, and the outer wall of the universal ball cabin does not contact the inner wall of the support ball groove.
[0011] Further, a plurality of threaded holes are uniformly arranged around the support ball groove on the main support base, and a plurality of circular groove holes are correspondingly arranged at the bottom of the top plate. A spring cylinder is fixed in each threaded hole on the main support base. The spring cylinder is provided with threads on the outside and is closed at the bottom. The bottom of the spring is located in the spring cylinder, and the top is located in the circular groove hole at the bottom of the top plate; The spring cylinder is integrally formed with the hexagonal nut sleeve at its top, and a plurality of hexagonal nuts for fixing are arranged on each spring cylinder; When the top plate is in a horizontal state, each spring is in a compressed state.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.
[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.
[0019] Refer to Figures 1 to 9 , the present invention includes a top plate 1 located at the bottom of the power distribution cabinet for carrying the power distribution cabinet above. An upwardly open and spiral water-cooled heat dissipation component is inlaid on the top surface of the top plate 1. The water-cooled heat dissipation component includes a water-cooled pipe 2 fixed in a spiral groove at the top of the top plate 1, that is, heat dissipation is carried out from the bottom of the power distribution cabinet. Heat conduction fins b202 and heat conduction fins a201 are respectively arranged on the inner and outer sides of the water-cooled pipe 2, which is beneficial to quickly transfer the heat generated by the power distribution cabinet to the top plate 1 and the middle water-cooled pipe 2 from both sides. The heat conduction fins b202 and heat conduction fins a201 meet at the center of the top plate 1 and a circular heat conduction plate 203 is fixed at the intersection. Since both heat conduction fins are spiral lines and both converge to the center, and the heat conduction plate 203 serves as an intermediate heat transfer medium to ensure heat transfer; A hollow universal ball cabin 3 is fixedly installed at the bottom of the top plate 1, and the universal ball cabin 3 is installed in the support ball groove 401 of the lower main support base 4 to ensure that the top plate 1 can tilt at any angle. A number of support balls 403 tangent to the universal ball cabin 3 are evenly arranged at the bottom of the main support base 4, and a number of limit balls 7 tangent to the universal ball cabin 3 are evenly arranged at the top of the main support base 4. The support balls 403 and the limit balls 7 avoid large-area contact of the universal ball cabin 3, that is, it is changed to point contact to ensure sufficient rotation efficiency, and the two are located at the upper and lower positions of the universal ball cabin 3 to accurately limit the universal ball cabin 3 to prevent it from shaking (note: the universal ball cabin 3 can rotate but cannot shake). The upper end of the universal ball cabin 3 protrudes outside the main support base 4, but the center of the ball is located inside the main support base 4, which is also a setting to ensure that the universal ball cabin 3 can tilt and rotate. However, since the maximum diameter of the universal ball cabin 3 is greater than the upper port diameter of the support ball groove 401, it cannot be separated. A number of springs 503 are evenly arranged around the universal ball cabin 3 on the main support base 4; The main support base 4 is fixed on the lower bottom plate 11. A number of pull rod pistons 8 are evenly arranged in a circle outside the main support base 4. The word "evenly" mentioned many times in this article is to make the overall force evenly distributed. The pull rod pistons 8 are respectively movably connected to the bottom plate 11 and the top plate 1 through the lower piston rod 801 and the upper piston rod 802.
[0020] Corner seats 101 are installed at the four corners of the top of the top plate 1 to support the bottom side of the power distribution cabinet. Air inlets 102 are arranged on both sides of the front end face of the top plate 1, and top plate cooling fans 103 are nested and installed on both sides of the rear end face correspondingly. A heat dissipation slot running through the front and back of the top plate 1 is arranged between the air inlets 102 and the top plate cooling fans 103, that is, heat dissipation is also carried out by accelerating the air flow through the top plate 11; Outer plates 105 are arranged around the bottom plate 11, and a telescopic bellows 104 is fixed between the outer plates 105 and the upper top plate 1. It can freely expand and contract when the top plate 1 tilts, and can provide comprehensive side protection.
[0021] One end of the water cooling pipe 2 is connected downward and communicates with the water outlet pipe 204, and the other end passes through the bottom of the water cooling and heat dissipation component and communicates with the water inlet pipe 205; The water outlet pipe 204 is connected to the water tank 206 below the top plate 1. The water inlet pipe 205 communicates with the water pump 207 on the water tank 206. A heat dissipation fan 208 is arranged on the side of the water tank 206. An opening is naturally arranged on the side outer plate 105 facing the heat dissipation fan 208. This belongs to the prior art and will not be elaborated. Components such as the liquid level sensor and temperature sensor in the water tank 206 belong to the prior art and will not be elaborated.
[0022] Inside the universal ball cabin 3, a spherical damping block 6 is provided, and the damping block 6 is suspended by a rope at the central setting at the bottom of the top plate 1. When the top plate 11 tilts, the damping block 6 resists the tilting force through a certain degree of reverse swing. The damping block 6 can be made of a lead block or a cast iron block with uniform mass, etc.; The universal ball cabin 3 is filled with damping liquid 601, and the damping liquid 601 can be a liquid with good heat dissipation effect such as water, which can not only effectively resist the tilting force when the top plate 1 and the universal ball cabin 3 are skewed, but also store part of the heat at the top and relieve the heat dissipation pressure above.
[0023] The supporting ball 403 is located in the ball groove 402 at the bottom of the main supporting base 4, and the two are in clearance fit. An oil injection groove hole 404 that communicates with the outside and slopes upward is provided on the groove wall of each ball groove 402, and lubricating oil can be injected to reduce the friction of the rotational connection; The center of the limiting ball 7 is lower than the upper end face of the main supporting base 4 and higher than the center height of the universal ball cabin 3, which plays a role in preventing falling off. The outer wall of the universal ball cabin 3 does not contact the inner wall of the supporting ball groove 401, that is, the contact area is reduced, and the surface contact is changed to point contact between the balls.
[0024] A number of threaded holes are evenly provided around the supporting ball groove 401 on the main supporting base 4, and a number of round groove holes are correspondingly provided at the bottom of the top plate 1. A spring cylinder 5 is fixed in each threaded hole on the main supporting base 4. Note: Since the weight of the upper power distribution cabinet is not evenly distributed, each spring cylinder 5 can be set to different heights (the elastic force of the spring 503 on the upper part is different) to ensure that after the power distribution cabinet is installed, the top plate 1 can still maintain a horizontal state with balanced upper and lower forces. The outside of the spring cylinder 5 is provided with threads and the bottom is closed. The bottom of the spring 503 is located in the spring cylinder 5, and the top is located in the round groove hole at the bottom of the top plate 1; The spring cylinder 5 and the hexagonal nut sleeve 502 at its top are integrated, which is convenient for using a wrench to screw and adjust the height. A number of hexagonal nuts 501 for fixing are provided on each spring cylinder 5 to fix the spring cylinder 5; When the top plate 1 is in a horizontal state, each spring 503 is in a compressed state. When the top plate 1 tilts to the maximum inclination angle, each spring 503 is still in a compressed state.
[0025] Universal ball heads 803 are provided at the ends of the lower piston rod 801 and the upper piston rod 802. The upper universal ball head 803 is rotatably connected to the ball head seat 805 installed at the bottom of the top plate 1, and the lower universal ball head 803 is rotatably connected to the ball head base 804 installed on the bottom plate 11. The centers of the upper and lower universal ball heads are located in their respective ball head seats to prevent falling off; Of course, the lower piston rod 801 and the upper piston rod 802 are in a vertical state when the top plate 1 is horizontal.
[0026] The combination mode of the universal ball head and the piston assembly can not only adapt to the up-and-down movement direction, but also adapt to the horizontal tilt angle. The pressure (or tensile force) provided by the piston assembly further assists the top plate to maintain horizontal; naturally, the specifications and heights of the piston assemblies are not unified either. The selection principle is the same as that of the spring cylinder 5, that is, the top plate 1 can still be maintained horizontal after the power distribution cabinet is installed.
[0027] A number of distance sensors 9 are evenly arranged between the ball head base 804 and the main support base 4. The distance sensors 9 face upward to detect the distance from the bottom of the top plate 1, and indirectly obtain the tilt angle of the top plate 1. An electric control box 901 for controlling all electrical components of this mechanism is also provided on the bottom plate 11. It is internally provided with conventional control components, electrical energy components, etc., which are all prior arts and will not be elaborated here.
[0028] Four limit posts 10 are also provided at the four corners of the bottom plate 11. This is the third safeguard in addition to the spring 503 and the piston assembly, and is used to abut against the maximum tilt angle of the top plate 1. A rubber ring 1001 is fixed at the top of the limit post 10, and an arc-shaped air cushion 1002 is arranged above the rubber ring 1001. The air cushion 1002 can elastically abut against the bottom of the top plate 1. Once the air cushion 1002 cannot bear it and explodes, the rubber ring 1001 can reduce the buffer to a certain extent.
[0029] Of course, the effect of this mechanism on up-and-down vibration is always limited. An anti-seismic device can be additionally installed at the bottom, which does not belong to the protection scope of this application and will not be elaborated here.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
