Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and more specifically, to a reactor and bidirectional converter that are easy to install. Background Technology

[0002] Due to the short distances between urban transportation stations, and the unique characteristics of subway operation, trains frequently start and brake, generating a large amount of energy during braking. The bidirectional converter not only acts as a rectifier, replacing the rectifier unit, but also feeds the braking energy back into the power grid, fully utilizing regenerative braking energy and improving the reliability of subway operation. The bidirectional converter consists of bidirectional converter units and converter transformer units, among other components. Structurally, a conventional bidirectional converter consists of two power cabinets and one control cabinet. The entire system is relatively large and heavy, exceeding three meters in length. Some components are quite heavy, especially the reactors in the power cabinets, which can weigh hundreds of kilograms.

[0003] It is difficult to install reactors manually. Usually, hoisting is used, which is very inefficient and can easily damage other structures in the cabinet. Moreover, subsequent maintenance is very inconvenient. Therefore, it is necessary to improve the installation method. Utility Model Content

[0004] To overcome the problem of inconvenient installation of reactors in the prior art, the first aspect of this utility model provides an easy-to-install reactor that can be transported and installed by forklift with high installation accuracy, effectively solving the problem of inconvenient hoisting.

[0005] The second aspect of this utility model provides a bidirectional converter.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an easy-to-install reactor, including: an upper clamp, a lower clamp and a coil, wherein the upper clamp and the lower clamp are respectively connected to the two ends of the coil, a forklift groove is provided at the bottom of the lower clamp, and position sensors for detecting the position of the forks are respectively provided on the outer sides of the forklift groove, and a controller and an alarm are also included, wherein the controller is electrically connected to the position sensors and the alarm.

[0007] In the technical solution of this utility model, a forklift slot is opened at the bottom of the lower clamp of the reactor, making it more convenient to install the reactor by transporting it with a forklift. The position sensors set on both sides of the forklift slot can detect the position of the forks and provide feedback through the controller and alarm. When the position of the forks deviates significantly, an alarm is issued to remind the operator to adjust, so that the forks can be placed more accurately in the forklift slot, ensuring the accuracy of the reactor installation.

[0008] Furthermore, the alarm is an audible and visual alarm, and the two alarms are respectively located on the outer sides of the forklift bay.

[0009] In this solution, alarms are triggered by two separate alarms on either side. The alarm will sound on the side where the forks are closer together, so that operators can be aware of the direction of the deviation and make timely adjustments.

[0010] Furthermore, the vertical cross-section at the entrance of the forklift slot gradually increases from the inside out.

[0011] Furthermore, the inner wall at the entrance of the forklift slot has an inclination angle of 15° to 25°.

[0012] In this design, an outward-facing angle is set at the entrance of the forklift slot to form a funnel-shaped guide entrance, which makes it easier for the forks to be placed into the forklift slot.

[0013] Furthermore, longitudinal beams are connected to both sides of the bottom of the lower clamp, and a load-bearing beam is connected between the longitudinal beams on both sides in a transverse direction.

[0014] In this design, the load-bearing capacity of the reactor bottom is improved by using longitudinal beams and load-bearing beams.

[0015] Furthermore, the load-bearing beam is arranged perpendicular to the extension direction of the forklift slot, and the load-bearing beam has a clearance opening at the extension position of the forklift slot.

[0016] In this design, the clearance opening on the load-bearing beam where the forklift arm passes through can prevent interference between the forks and the load-bearing beam when the forks are moving in and out. At the same time, the load-bearing beam can also improve the structural stability when transporting the reactor.

[0017] Furthermore, an angle steel is connected to the side of the longitudinal beam facing the forklift slot, one side of the angle steel is fixedly connected to the lower clamp, and the other side of the angle steel is fixedly connected to the position sensor.

[0018] In this scheme, angle steel is used to facilitate the mounting of the position sensor on the reactor.

[0019] Furthermore, a dust cover is connected to the outside of the position sensor, and the dust cover has an opening in the detection path of the position sensor.

[0020] In this solution, the dust cover can, to a certain extent, prevent the influence of dust and oil on the position sensor, thus ensuring the detection accuracy of the position sensor.

[0021] In this solution, the position sensor is a photoelectric sensor.

[0022] Furthermore, two position sensors are provided along the extension direction of the forklift slot, and the position sensors are symmetrically arranged on both sides of the forklift slot.

[0023] In this solution, two position sensors symmetrically arranged on both sides along the extension direction of the forklift slot can detect the tilting deviation of the forks, ensuring that the forks extend parallel to the forklift slot and guaranteeing the installation accuracy of the reactor.

[0024] Furthermore, the inner wall of the forklift slot is provided with a wear-resistant layer.

[0025] In this solution, a wear-resistant layer is installed on the inner wall of the forklift slot to prevent the reactor from being damaged by collision between the forks and the side wall of the forklift slot.

[0026] A bidirectional converter employs the aforementioned reactor.

[0027] In this scheme, the bidirectional converter uses the aforementioned reactor, making installation more convenient.

[0028] Compared with the prior art, the beneficial effects of this utility model are: I. The reactor of this utility model is easy to install. By opening a forklift slot at the bottom of the lower clamp of the reactor, it is more convenient to install the reactor by transporting it with a forklift. The position sensors set on both sides of the forklift slot can detect the position of the forks and provide feedback through the controller and alarm. When the position of the forks deviates significantly, an alarm is issued to remind the operator to adjust, so that the forks can be more accurately placed in the forklift slot, ensuring the accuracy of the reactor installation.

[0029] Second, the bidirectional converter of this utility model, due to the use of the aforementioned easy-to-install reactor, has higher efficiency during installation and is also easier to maintain, reducing installation and maintenance costs. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0034] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1 refer to Figures 1 to 3 This embodiment discloses an easy-to-install reactor, including: an upper clamp 1, a lower clamp 2, and a coil 3. The upper clamp 1 and the lower clamp 2 are respectively connected to the two ends of the coil 3. A forklift slot 21 is provided at the bottom of the lower clamp 2. Position sensors 4 for detecting the position of the forks are respectively provided on the outer sides of the forklift slot 21. The reactor also includes a controller and an alarm. The controller is electrically connected to the position sensors 4 and the alarm.

[0035] In this embodiment, a forklift slot 21 is provided at the bottom of the lower clamp 2 of the reactor, making it more convenient to install the reactor by transporting it with a forklift. Position sensors 4 installed on both sides of the forklift slot 21 can detect the position of the forks, and feedback is provided through a controller and alarm. When the fork position deviates significantly, an alarm is triggered to remind the operator to adjust, ensuring the forks are more accurately positioned in the forklift slot 21 and guaranteeing the accuracy of the reactor installation. The position sensors 4 can be positioned 5 cm from the entrance of the forklift slot 21, with two symmetrically arranged rotating diffuse reflection photoelectric sensors, such as the Omron E3Z-D61, monitoring the deviation of the forks on the left and right sides to ensure coverage of the main detection area where the forks enter. A laser calibration line using a 650nm red laser can also be installed inside the forklift slot 21, aligned with the center line of the forklift slot 21, to assist the operator in aligning the forks with the forklift slot 21.

[0036] In some other embodiments, two position sensors 4 are provided along the extension direction of the forklift slot 21, symmetrically arranged on both sides of the forklift slot 21. By using two position sensors 4 symmetrically arranged on both sides of the forklift slot 21, the tilting or offset of the forks can be detected, ensuring that the forks extend parallel to the forklift slot 21 and guaranteeing the installation accuracy of the reactor. When both position sensors 4 along the extension direction of the forklift slot 21 detect that the forklift slot 21 is in the correct position, it indicates that the forks have not tilted or offset, improving installation accuracy.

[0037] In this embodiment, the alarm is an audible and visual alarm, and two alarms are respectively installed on the outer sides of the forklift slot 21. The alarms on both sides sound an alarm, with the alarm on the side where the forks are closer emitting the warning, allowing operators to know the direction of deviation and make timely adjustments. The audible and visual alarm can be of model LTE-1101J, which is linked with the position sensor 4 to provide real-time feedback on the fork offset. When the forklift forks enter the forklift slot 21, if the position sensor 4 detects an offset of 1mm to 2mm, the alarm flashes a green light; if the fork offset is greater than 2mm, the alarm lights up a red light and sounds a buzzer, controlling the fork offset to within 2mm. The audible and visual alarm can be installed on the front panel of the entire equipment cabinet; the specific location is not specified.

[0038] In this embodiment, the vertical cross-section of the forklift slot 21 gradually increases from the inside to the outside, and the inner sidewall of the forklift slot 21 has an inclination angle of 15° to 25°. The outward inclination angle at the entrance of the forklift slot 21 forms a funnel-shaped guide entrance, making it easier to insert the forks into the forklift slot 21.

[0039] refer to Figure 2 and Figure 3 The lower clamp 2 has longitudinal beams 5 connected to both sides of its bottom, and a load-bearing beam 6 is connected transversely between the longitudinal beams 5 on both sides. In this embodiment, the load-bearing capacity of the reactor bottom is improved by the longitudinal beams 5 and the load-bearing beam 6. The load-bearing beam 6 is made of Q355B high-strength steel, and the load-bearing beam 6 is connected to the longitudinal beams 5 by welding.

[0040] refer to Figure 2 The load-bearing beam 6 is arranged perpendicular to the extension direction of the forklift slot 21, and the load-bearing beam 6 has a clearance opening at the extension position of the forklift slot 21.

[0041] In this embodiment, the clearance opening on the load-bearing beam 6 where it passes the forklift arm can prevent the forks from interfering with the load-bearing beam 6 when they are moving in and out. At the same time, the load-bearing beam 6 can also improve the structural stability when transporting the reactor.

[0042] refer to Figure 3 An angle steel 7 is connected to the side of the longitudinal beam 5 facing the forklift slot 21. One side of the angle steel 7 is fixedly connected to the lower clamp 2, and the other side of the angle steel 7 is fixedly connected to the position sensor 4. In this embodiment, the angle steel 7 is used to facilitate the mounting of the position sensor 4 on the reactor.

[0043] Example 2 refer to Figures 1 to 3 Similar to Embodiment 1, this embodiment discloses an easily installable reactor, comprising: an upper clamp 1, a lower clamp 2, and a coil 3. The upper clamp 1 and the lower clamp 2 are respectively connected to the two ends of the coil 3. A forklift slot 21 is formed at the bottom of the lower clamp 2. Position sensors 4 for detecting the position of the forks are respectively provided on the outer sides of the forklift slot 21. The embodiment also includes a controller and an alarm. The controller is electrically connected to the position sensors 4 and the alarm. The alarm is an audible and visual alarm, and two alarms are respectively located on both sides of the forklift slot 21. The vertical cross-section at the entrance of the forklift slot 21 gradually increases from the inside to the outside, and the inner sidewall at the entrance of the forklift slot 21 has an inclination angle of 15° to 25°. Longitudinal beams 5 are connected to the bottom two sides of the lower clamp 2, and a load-bearing beam 6 is connected transversely between the longitudinal beams 5 on both sides. The load-bearing beam 6 is arranged perpendicular to the extension direction of the forklift slot 21, and the load-bearing beam 6 has a clearance opening at the extension position of the forklift slot 21.

[0044] The difference between this embodiment and Embodiment 1 is that, in this embodiment, a dust cover (not shown in the figure) is connected to the outside of the position sensor 4, and the dust cover has an opening in the detection path of the position sensor 4. In this embodiment, the dust cover can, to a certain extent, prevent the influence of dust and oil on the position sensor 4, ensuring the detection accuracy of the position sensor 4. The dust cover can be made of transparent PC material. In this embodiment, the position sensor 4 is a photoelectric sensor. The position sensor 4 has a transmitting end 41, and the dust cover will not block the transmitting end 41 of the position sensor 4.

[0045] In this embodiment, the inner wall of the forklift slot 21 is provided with a wear-resistant layer. In this embodiment, by providing a wear-resistant layer on the inner wall of the forklift slot 21, damage to the reactor caused by collision between the forks and the side wall of the forklift slot 21 is prevented. The wear-resistant layer can be a polyurethane wear-resistant layer with a thickness of 5mm.

[0046] Example 3 refer to Figure 4 This embodiment discloses a bidirectional converter that uses a reactor as described in Embodiment 1 or Embodiment 2. (See reference...) Figures 1 to 3The reactor includes an upper clamp 1, a lower clamp 2, and a coil 3. The upper clamp 1 and the lower clamp 2 are respectively connected to the two ends of the coil 3. A forklift slot 21 is formed at the bottom of the lower clamp 2. Position sensors 4 for detecting the position of the forks are respectively arranged on the outer sides of the forklift slot 21. The reactor also includes a controller and an alarm. The controller is electrically connected to the position sensors 4 and the alarm. The alarm is an audible and visual alarm, and two alarms are respectively arranged on both sides of the forklift slot 21. The vertical cross-section of the entrance of the forklift slot 21 gradually increases from the inside to the outside, and the inner sidewall of the entrance of the forklift slot 21 has an inclination angle of 15° to 25°. The bottom sides of the lower clamp 2 are connected to longitudinal beams 5, and a load-bearing beam 6 is connected transversely between the two longitudinal beams 5. The load-bearing beam 6 is arranged perpendicular to the extension direction of the forklift slot 21, and a clearance opening is formed at the extension position of the forklift slot 21.

[0047] The reactor used in this embodiment has a forklift slot 21 at the bottom of the lower clamp 2 of the reactor, which makes it more convenient to install the reactor by transporting it with a forklift. The position sensors 4 set on both sides of the forklift slot 21 can detect the position of the forks and provide feedback through the controller and alarm. When the position of the forks deviates significantly, an alarm is issued to remind the operator to adjust, so that the forks can be placed more accurately in the forklift slot 21, ensuring the accuracy of the reactor installation.

The outer cabinet also contains two power cabinets and one control cabinet. The remaining components inside the bidirectional converter and their connections are existing technology and will not be described further here.
