[0002] A distribution transformer is a static electrical device in a power distribution system that transforms AC voltage and current according to the law of electromagnetic induction to transmit AC power. When constructing a substation, it needs to be connected to the total construction power supply.

[0003] The existing three-dimensional distribution transformer for substation construction power supply can be specifically referred to the Chinese patent with authorization announcement number CN213183904U, which discloses a three-dimensional distribution transformer for substation construction power supply, including a distribution transformer core, the distribution transformer core includes three first cores, the upper and lower ends of two adjacent first cores are connected to the second core, and the second core is vertically connected to the first core; the first core is sleeved with a coil; the three-dimensional distribution transformer is an environmentally friendly natural ester insulating oil transformer for construction power supply that is easy to install, disassemble, safe and environmentally friendly. This type of transformer has excellent flame retardant properties, and has an excellent biodegradability in case of insulating oil leakage. It is suitable for environmentally sensitive areas such as water sources, farmlands, scenic spots, streets, and industrial and commercial complexes, scientific research institutes, mines, and other units that are sensitive to fire safety.

[0004] However, when the above-mentioned distribution transformer is under construction in a substation, some construction works are short-lived and usually only work for a few days to a week. After the construction work is completed, the distribution transformer needs to be disassembled and transported to the next construction site. In this case, the traditional distribution transformer installation method is only suitable for long-term construction work. Short-term construction work will make the disassembly and installation of the distribution transformer complicated, and frequent installation and disassembly may cause damage to the distribution transformer. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, a three-dimensional distribution transformer for substation construction power supply is proposed, which can solve the problem that frequent installation and disassembly of the current distribution transformer during substation construction may cause damage to the distribution transformer.

[0006] The technical solution adopted by the utility model to solve its technical problems is: the three-dimensional distribution transformer for substation construction power supply described in the utility model includes a device body, four groups of universal wheels are fixedly connected to the bottom end of the device body, a moving mechanism is arranged at the bottom end of the device body, the moving mechanism includes two groups of moving grooves, and the two groups of the moving grooves are opened at the bottom end of the device body, the two ends of the inside of the moving grooves are rotatably connected with screws, the two ends of the screws are threadedly connected to moving blocks on the outer sides, the bottom end of the moving block is fixedly connected with a first hinge seat, the first hinge seat is hinged to one end of a rotating rod, the other end of the rotating rod is hinged to a second hinge seat, the bottom end of the second hinge seat is provided with a support plate, and the top end of the support plate is fixedly connected to the second hinge seat.

[0007] Preferably, the threads at both ends of the screw are in opposite directions, and a limiting column is fixedly connected to the outer side of the middle portion of the screw.

[0008] Preferably, the moving block is inside the moving groove, and the cross-sectional dimension of the moving block is the same as the cross-sectional dimension of the moving groove.

[0009] Preferably, a transmission mechanism is provided on one side of the bottom end of the device body, and the transmission mechanism includes two groups of rotating columns, and the two groups of rotating columns penetrate the device body and are fixedly connected to one end of the two groups of screw rods, and a transmission belt is sleeved on the outer side of the rotating column.

[0010] Preferably, a protective shell is provided on the outer side of the transmission belt, and the protective shell is fixedly connected to the device body.

[0011] Preferably, a motor is provided at one end of the protective shell, and an output shaft of the motor passes through the protective shell and is fixedly connected to one group of rotating columns.

[0012] The utility model is beneficial in that:

[0013] The utility model realizes, through the structural design of the moving mechanism, that when the device body is moved to the construction site for work via the universal wheels, the motor is turned on to cooperate with the transmission mechanism to drive the two sets of screws to rotate, thereby driving the moving blocks at both ends of the screws and the first hinge seat to move toward each other, so that the rotating rod cooperates with the first hinge seat and the second hinge seat to rotate, and the support plate is lowered so that the bottom end of the support plate contacts the ground and supports the device body, and the universal wheels are lifted to prevent it from contacting the ground, so that the device body can be conveniently transported via the universal wheels, and the support plate can be made to touch the ground before being put into work, so as to work stably, solving the problem that the current distribution transformer needs to be moved to different construction sites due to the short duration of some construction work during the substation construction work, and the short-term construction work makes the disassembly and installation of the distribution transformer complicated, and the frequent installation and disassembly may cause damage to the distribution transformer;

[0014] The utility model realizes that the two groups of rotating columns are set through the same group of transmission belts through the structural design of the transmission mechanism. Therefore, only one group of rotating columns needs to rotate for the other group of rotating columns to rotate. That is, when the motor is turned on, it will drive the two groups of rotating columns and the two groups of screws to rotate together, which solves the problem that two groups of motors are needed to control the rotation of the two groups of screws respectively to drive the lifting plate to be lifted stably and parallel to the ground, thereby reducing production costs.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 - Figure 4As shown, a three-dimensional distribution transformer for power supply for substation construction includes a device body 1, four sets of universal wheels 2 are fixedly connected to the bottom end of the device body 1, a moving mechanism is arranged at the bottom end of the device body 1, the moving mechanism includes two sets of moving grooves 3, and the two sets of moving grooves 3 are opened at the bottom end of the device body 1, the two ends of the inside of the moving grooves 3 are rotatably connected with screw rods 4, the two ends of the screw rods 4 are threadedly connected to moving blocks 5, the bottom end of the moving block 5 is fixedly connected with a first hinge seat 6, the first hinge seat 6 is hinged to one end of a rotating rod 7, the other end of the rotating rod 7 is hinged to a second hinge seat 8, a support plate 9 is arranged at the bottom end of the second hinge seat 8, and the top end of the support plate 9 is fixedly connected to the second hinge seat 8;

[0023] During operation, when the device body 1 is moved to the construction site through the universal wheel 2 to work, turning on the motor 14 and cooperating with the transmission mechanism can drive the two sets of screws 4 to rotate, thereby driving the moving blocks 5 and the first hinge seat 6 at both ends of the screw 4 to move toward each other, so that the rotating rod 7 cooperates with the first hinge seat 6 and the second hinge seat 8 to rotate, and lowers the support plate 9 so that the bottom end of the support plate 9 contacts the ground and supports the device body 1, and the universal wheel 2 is lifted to prevent it from contacting the ground.

[0024] Further, such as Figure 4 As shown, the threads at both ends of the screw rod 4 are in opposite directions, and the outer side of the middle of the screw rod 4 is fixedly connected to the limiting column 10;

[0025] During operation, since the threads at both ends of the screw rod 4 are in opposite directions, the moving blocks 5 at both ends of the screw rod 4 can move toward each other when the screw rod 4 rotates, so that the first hinge seats 6 at both ends of the screw rod 4 move toward each other, so that the movement of the first hinge seat 6 will cooperate with the second hinge seat 8 to rotate the rotating rod 7, thereby realizing the lifting and lowering of the support plate 9, and the limiting column 10 can limit the moving position of the moving block 5 on the screw rod 4. Because when the first hinge seat 6 and the second hinge seat 8 on the same side of the screw rod 4 are vertically aligned, the device body 1, the two sets of rotating rods 7 and the support plate 9 form a parallelogram, which is unstable. In order to prevent this situation, the moving position of the moving block 5 and the first hinge seat 6 is limited by the limiting column 10, so that the device body 1, the two sets of rotating rods 7 and the support plate 9 are always in a trapezoidal state, which can ensure the stability of the device body 1.

[0026] Further, such as Figure 4 As shown, the moving block 5 is inside the moving groove 3, and the cross-sectional dimension of the moving block 5 is the same as the cross-sectional dimension of the moving groove 3;

[0027] During operation, the rotation of the screw 4 will cause the moving block 5 to have the same tendency to rotate. Since the cross-sectional size of the moving block 5 is the same as the cross-sectional size inside the moving groove 3, the tendency of the moving block 5 to rotate will be hindered by the moving groove 3. Due to the characteristics of the threaded connection between the moving block 5 and the screw 4, the moving block 5 can move on the screw 4 as the screw 4 rotates.

[0028] Further, such as Figure 2 As shown, a transmission mechanism is provided at one side of the bottom end of the device body 1, and the transmission mechanism includes two sets of rotating columns 11, and the two sets of rotating columns 11 penetrate the device body 1 and are fixedly connected to one end of the two sets of screw rods 4, and a transmission belt 12 is sleeved on the outer side of the rotating columns 11;

[0029] During operation, through the structural design of the transmission mechanism, the two groups of rotating columns 11 are arranged through the same group of transmission belts 12, so only one group of rotating columns 11 needs to rotate, and the other group of rotating columns 11 will also rotate, that is, when the motor 14 is turned on, it will drive the two groups of rotating columns 11 and the two groups of screws 4 to rotate together, which solves the problem of fixed connection between the lifting plate and the second hinge seat 8. Therefore, if you want the lifting plate to be stable and parallel to the ground, the two groups of screws 4 need to rotate at the same time. Originally, it was necessary to install two groups of motors 14 to control the rotation of the two groups of screws 4 respectively, which would lead to the problem of increased production costs.

[0030] Further, such as Figure 2 As shown, a protective shell 13 is provided on the outside of the transmission belt 12, and the protective shell 13 is fixedly connected to the device body 1;

[0031] During operation, the transmission belt 12 is the key to the common rotation of the two groups of rotating columns 11 in the transmission mechanism, so the transmission belt 12 cannot fall off the rotating column 11, and the protective shell 13 can prevent the transmission belt 12 from falling off from the outside of the rotating column 11. At the same time, the protective shell 13 can also protect external construction workers from touching the transmission belt 12 or the rotating column 11 when the transmission mechanism is working.

[0032] Further, such as Figure 2 As shown, a motor 14 is disposed at one end of the protective shell 13, and the output shaft of the motor 14 passes through the protective shell 13 and is fixedly connected to one set of rotating columns 11;

[0033] When working, the motor 14 is the power source of the transmission mechanism, and the operation of the motor 14 can drive the rotating column 11 connected thereto to rotate.

[0034] Working principle: push the device body 1 to the construction site. At this time, turn on the motor 14 to drive the rotating column 11 connected to it to rotate, thereby driving the transmission belt 12 and another group of rotating columns 11 to rotate, that is, the two groups of screws 4 rotate, and as the screw 4 rotates, the moving blocks 5 at both ends of the screw 4 drive the first hinge seat 6 to move toward the limit column 10. As the moving block 5 moves and cooperates with the second hinge seat 8 and the rotating rod 7 to rotate, the support plate 9 slowly descends and gradually contacts the ground to lift the device body 1 and the universal wheel 2. At this time, the device body 1 can be put into construction. When the construction is completed, turn on the motor 14 in the opposite direction to make the screw 4 reverse, thereby driving the support plate 9 to rise, and the universal wheel 2 touches the ground to transport the device body 1 to the next construction point.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
