Description

Technical Field

[0001] The invention relates to the technical field of meter boxes, and in particular to an electric energy meter box. Background Art

[0002] The main function of the electricity meter box is to measure electricity. The electricity meter is installed inside the shell. The electricity meter box accurately measures electricity, records electricity consumption in different time periods, and provides users with accurate metering data, which can help them understand their electricity usage and control costs.

[0003] After searching the existing published technical documents, the Chinese patent publication number CN209086272U discloses an electric energy meter box with good insulation performance, which is mainly fixed on the inner surface of the box door through a mounting block, and a lighting lamp is installed on the mounting block. There are three lighting lamps, which are evenly and equidistantly distributed. The radiator is fixed on one side of the mounting block, and the radiator includes a drive motor and a cooling fan. It has the advantages of good insulation performance, high safety, good heat dissipation, and convenient use. However, the electric energy meter box has the following defects.

[0004] When the electric energy meter box is in use, it is necessary to connect the wiring harness through the electric energy meter. However, during the use of the wiring harness, the wiring harness is locked by bolts. The bolts may become loose due to thermal expansion and contraction problems and vibrations generated by the operation of other power distribution equipment. Therefore, the loose wiring harness causes the electric energy meter box to malfunction. This requires maintenance personnel to spend a long time on-site for maintenance, and it is difficult to detect the loose fault in time and achieve automatic locking. The later maintenance and use of the electric energy meter box is more time-consuming and labor-intensive. For this purpose, an electric energy meter box is provided. Summary of the invention

[0005] To this end, the present invention provides an electric energy metering box to solve the technical problems existing in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electric energy meter box, comprising a box shell, an electric energy meter for electric energy metering is fixedly connected to one side of the inner wall of the box shell, a plurality of wiring harnesses are plugged into the bottom end of the electric energy meter, and a loose detection mechanism is embedded and installed in front of the electric energy meter; the loose detection mechanism comprises a plurality of locking bolts embedded and installed in front of the electric energy meter, and a concave frame plate welded to the box shell is provided on one side of the electric energy meter; a sleeve slide is slidably connected to the inner wall of the concave frame plate, and a distance sensor is embedded and fixedly connected to the bottom end of the sleeve slide, and a detection rotating block welded to the locking bolt is installed below the distance sensor; a screw is threadedly connected to the inner wall of the sleeve slide, and a driving motor for driving the screw to rotate is fixedly installed at one end of the concave frame plate; a horizontal precision docking locking mechanism is installed on one side of the sleeve slide and close to the distance sensor; an electric cylinder fixedly connected to the box shell is provided on one side of each of the wiring harnesses, and a vertical precision docking locking mechanism is provided at the pushing end of the electric cylinder.

[0007] Preferably, the plurality of locking bolts are threadedly connected to the electric energy meter, and the plurality of locking bolts are equidistantly arranged in sequence from left to right, the cross-sectional shape of the concave frame plate is concave, the upper surface of the detection rotating block and the bottom end surface of the distance sensor are both in the same horizontal plane, the front of the box shell is connected with a cover body, and a transparent plate is glued and fixed to the inner wall of the cover body, and the transparent plate is used for viewing the electric energy meter, and a wiring groove is opened at the bottom end of the box shell, and a wireless controller fixedly connected to the box shell is provided on one side of the wiring groove.

[0008] When the electric energy meter box of this embodiment is used, the drive motor drives the screw to rotate forward, and the screw carries the sleeve slide to move right under the action of the thread transmission force, and the sleeve slide drives the distance sensor to move right. The distance sensor performs rightward movement detection on multiple detection rotating blocks. When the top surface of one detection rotating block is not parallel to the bottom surface of the distance sensor, and the distance value sensed by the distance sensor for the detection rotating block is different from the distance value set by the wireless controller, it is known that the locking bolt on the detection rotating block is loosened by rotation, and the wire head of the wiring harness is loosened and falls, and the drive of the drive motor is turned off through the wireless controller.

[0009] Preferably, the transverse precision docking locking mechanism comprises a slide frame fixedly mounted on one side of the sleeve slide plate and close to the distance sensor; the inner wall of the slide frame is rotatably connected with a driving screw, and a reduction motor is fixedly mounted on one side of the slide frame, the reduction motor is used to drive the driving screw to rotate, and the outer wall of the driving screw is threadedly connected with a sleeve slide block close to the reduction motor;

[0010] A collar is welded at the bottom end of the sleeve slider, a rotating shaft is rotatably connected to the inner wall of the collar, a hexagonal sleeve is welded at one end of the rotating shaft, a torque sensor is fixedly installed at the other end of the rotating shaft, and the torque sensor is used to sense the torque of the rotating shaft; a driving shaft is welded at one end of the rotating shaft, and a transmission motor is coaxially connected to one end of the driving shaft, and a support plate fixedly connected to the sleeve slider is installed at the top of the transmission motor;

[0011] A support block is fixedly installed on the inner wall of the hexagonal sleeve, and a verification distance sensor is embedded and fixedly installed on one side of the support block. One side of the verification distance sensor is provided with an induction block fixedly connected to the detection rotating block, and the sleeve slider is slidably connected to the sliding frame, and the sleeve slider and the sliding frame are both made of stainless steel; the vertical cross-section of one end of the hexagonal sleeve close to the rotating shaft is hexagonal, and the transmission motor and the torque sensor are fixedly connected to the support plate, and the support plate is made of stainless steel.

[0012] When the electric energy meter box of this embodiment is used, the transmission motor carries the driving shaft to rotate, and the rotating shaft carries the hexagonal sleeve to rotate. The hexagonal sleeve drives the support block to rotate, and when the distance sensor is rotated, when the sensing end of the distance sensor is on the same horizontal line as the center point of the sensing block, the distance of the sensing block of the distance sensor is the distance set by the wireless controller, and the inner wall of the hexagonal sleeve can be precisely plugged with the locking bolt horizontally, and the wireless controller turns off the transmission motor at the same time. The reduction motor drives the driving screw to rotate inside the sliding frame, and the sleeved slider carries the support plate to synchronize the torque sensor and the transmission motor to move right, and the hexagonal sleeve is sleeved on the outer wall of the locking bolt. The transmission motor is continued to be started through the wireless controller, and the driving shaft drives the torque sensor sensing shaft to rotate, and the torque sensor sensing shaft drives the rotating shaft to rotate inside the collar. The hexagonal sleeve drives the locking bolt to rotate, and the end of the locking bolt is squeezed onto the wire harness head. When the shaft torque value sensed by the torque sensor is the same as the torque value set by the wireless controller, the transmission motor is turned off through the wireless controller, and the loose locking bolt can be quickly docked and locked, which is convenient for later maintenance and saves time and effort.

[0013] Preferably, the vertical precision docking locking mechanism includes a pressure sensor fixedly installed on the pushing end of the electric cylinder; a push block is fixedly connected to the sensing end of the pressure sensor, and a slide bar and a micro-motion distance sensor are sequentially arranged on one side of the push block from the outside to the inside, and the push block and the micro-motion distance sensor are fixedly connected to the slide bar; the inner wall of the slide bar is slidably connected to the outer wall of the wiring harness, a slide column is welded to the top of the slide bar, a micro-motion bar is slidably connected to the outer wall of the slide column, and the inner wall of the micro-motion bar is fixedly connected to the outer wall of the wiring harness, the bottom end face of the micro-motion bar is parallel to the top end face of the slide bar, and the micro-motion bar and the slide bar are both made of silicon oxide material.

[0014] When the electric energy meter box of this embodiment is used, when the wire harness falls, it will drive the micro-movement bar to move downward, and the slide bar supports the micro-movement distance sensor. When the micro-movement distance sensor senses that the micro-movement bar falls and the distance changes, the electric cylinder is started through the wireless controller. The pressure sensor drives the push block to move upward, and the slide bar drives the micro-movement distance sensor to move upward. The top surface of the slide bar contacts the bottom surface of the micro-movement bar to achieve the upper push. The wire head at the top of the wire harness is squeezed on the inner wall of the electric energy meter to generate a certain pressure value. When the pressure value set by the pressure sensor is the same as the pressure value set by the wireless controller, the electric cylinder is closed through the wireless controller.

[0015] The present invention has the following advantages:

[0016] 1. The present invention adopts a looseness detection mechanism, and a driving motor drives the screw to rotate forward. The screw carries the sleeve slide to move right under the action of the thread transmission force, and the sleeve slide drives the distance sensor to move right. The distance sensor performs right movement detection on multiple detection rotating blocks. When the top end surface of the detection rotating block and the bottom end surface of the distance sensor are not in a parallel state, and at the same time, when the distance value sensed by the distance sensor for the detection rotating block is different from the distance value set by the wireless controller, it is known that the locking bolt on the detection rotating block is rotationally loose, the loose locking bolt is known in time, and the locking bolt is remotely and automatically locked, which saves time and effort in the later maintenance of the electric energy meter box.

[0017] 2. The present invention adopts a horizontal precise docking locking mechanism. The transmission motor carries the driving shaft to rotate. When the sensing end of the distance sensor and the center point of the sensing block are on the same horizontal line, the reduction motor drives the driving screw to rotate inside the sliding frame. The sleeved slider carries the support plate to make the torque sensor and the transmission motor move to the right synchronously. The hexagonal sleeve is sleeved on the outer wall of the locking bolt, and the transmission motor drives the driving shaft to rotate. The locking bolt is threadedly rotated and moved on the electric energy meter to achieve docking and locking of the locking bolt according to the specified torque. There is no need for maintenance personnel to arrive at the site to separately maintain the locking bolt, and maintenance is more time-saving and labor-saving.

[0018] 3. The present invention uses a vertical precise docking locking mechanism. When the wire harness falls, it will drive the micro-movement bar to move downward. The micro-movement bar moves downward along the outer wall of the sliding column, and the micro-movement distance sensor senses the distance of the bottom end of the micro-movement bar. When the micro-movement distance sensor senses that the micro-movement bar falls and causes a distance change, the electric cylinder is started by the wireless controller, and the slide bar drives the micro-movement distance sensor to move upward. The top surface of the slide bar contacts the bottom surface of the micro-movement bar to achieve upward push. The wire head at the top of the wire harness is squeezed against the inner wall of the electric energy meter to generate a certain pressure value. When the pressure value set by the pressure sensor is the same as the pressure value set by the wireless controller, the electric cylinder is closed by the wireless controller. In this way, the loose wire harness can be vertically docked and locked in time, and there is no need for maintenance personnel to arrive at the site to maintain the locking bolts separately, so maintenance is more time-saving and labor-saving.

[0019] According to the mutual influence of the above multiple effects, the locking bolt on the detection rotating block is first rotated and loosened, and the loose locking bolt is detected in time, and then the loose wire harness is vertically docked and locked in time, and finally the sensing end of the distance sensor and the center point of the sensing block are checked to be on the same horizontal line, and the hexagonal sleeve is sleeved on the outer wall of the locking bolt to achieve rotational locking. In summary, the loose wire harness and locking bolt are detected in time, the wire harness is automatically plugged and locked vertically, and the locking bolt is automatically docked and locked horizontally. The loose wire harness can be locked without the need for maintenance personnel to arrive at the site, and the later maintenance and use of the electric energy meter box is more time-saving and labor-saving.

[0038] In this embodiment, as shown in the attached Figure 8 - Fig.10 As shown, the vertical precision docking locking mechanism includes a pressure sensor 30 fixedly installed at the pushing end of the electric cylinder 29; a push block 31 is fixedly connected to the sensing end of the pressure sensor 30, and a slide bar 32 and a micro-motion distance sensor 33 are arranged on one side of the push block 31 from the outside to the inside, and the push block 31 and the micro-motion distance sensor 33 are fixedly connected to the slide bar 32; the inner wall of the slide bar 32 is slidably connected to the outer wall of the wiring harness 3, a slide column 34 is welded to the top of the slide bar 32, and a micro-motion bar 35 is slidably connected to the outer wall of the slide column 34, and the inner wall of the micro-motion bar 35 is fixedly connected to the outer wall of the wiring harness 3. The bottom end surface of the micro-motion bar 35 is parallel to the top end surface of the slide bar 32, and the micro-motion bar 35 and the slide bar 32 are both made of silicon oxide.

[0039] The use process of the electric energy meter box of the present invention is as follows:

[0040] Step 1: When using the electric energy meter, fix the box shell 1 at the power distribution position, rotate the cover 11, and the cover 11 can encapsulate and protect the box shell 1. The multiple wiring harnesses 3 on the electric energy meter 2 can be connected to the line, and the electric energy can be measured through the electric energy meter 2. At the same time, the transparent plate 12 can see the electric energy measurement value displayed by the electric energy meter 2 inside the box shell 1.

[0041] Step 2: During the looseness detection, the drive motor 10 is started by the wireless controller 14, and the drive motor 10 drives the screw 9 to rotate forward. The screw 9 carries the sleeve slide 6 to move right under the action of the thread transmission force, and the sleeve slide 6 moves right along the inner wall of the concave frame plate 5, and the sleeve slide 6 drives the distance sensor 7 to move right. The distance sensor 7 performs rightward movement detection on multiple detection rotating blocks 8. The gap distance between the two detection rotating blocks 8 sensed by the distance sensor 7 is an infinite value, which is the normal distance value allowed by the wireless controller 14. At this time, the drive motor 10 will not stop driving. When the top surface of one of the detection rotating blocks 8 is not in a parallel state with the bottom surface of the distance sensor 7, and the distance value sensed by the distance sensor 7 to the detection rotating block 8 is different from the distance value set by the wireless controller 14, it is known that the locking bolt 4 on the detection rotating block 8 is loose in rotation, and one end of the locking bolt 4 is difficult to be firmly locked on the wire head of the wiring harness 3. The wire head of the wiring harness 3 is loose, and the wiring harness 3 moves downward by falling by its own weight. The drive motor 10 is turned off by the wireless controller 14 to perform vertical precise docking and locking.

[0042] Step 3: When the wire harness 3 is precisely docked and locked, the falling of the wire harness 3 will drive the micro-movement bar 35 to move downward, and the micro-movement bar 35 will move downward along the outer wall of the slide column 34. The slide bar 32 supports the micro-movement distance sensor 33, and the micro-movement distance sensor 33 performs distance sensing on the bottom end of the micro-movement bar 35. When the micro-movement distance sensor 33 senses that the micro-movement bar 35 falls and causes a distance change, the electric cylinder 29 is activated through the wireless controller 14. The electric cylinder 29 pushes the pressure sensor 30 to move upward, and the pressure sensor 30 drives the push block 31 to move upward, and the push block 31 carries the slide bar 32 to move upward along the outer wall of the wire harness 3. The slide bar 32 drives the micro-motion distance sensor 33 to move upward, and the top end surface of the slide bar 32 contacts the bottom end surface of the micro-motion bar 35 to achieve upward pushing, and the micro-motion bar 35 drives the wire ends at the top end of the wiring harness 3 to achieve vertical plugging inside the electric energy meter 2. The wire ends at the top end of the wiring harness 3 are squeezed against the inner wall of the electric energy meter 2 to generate a certain pressure value. When the pressure value set by the pressure sensor 30 is the same as the pressure value set by the wireless controller 14, the electric cylinder 29 is closed by the wireless controller 14.

[0043] Step 4: When the horizontal precise docking and locking are performed, the transmission motor 24 is started to rotate through the wireless controller 14, and the transmission motor 24 drives the driving shaft 23 to rotate. The driving shaft 23 causes the sensing end of the torque sensor 22 to drive the rotating shaft 20 to rotate, and the rotating shaft 20 drives the hexagonal sleeve 21 to rotate. The hexagonal sleeve 21 drives the support block 26 to rotate, and the support block 26 drives the verification distance sensor 27 to rotate. When the verification distance sensor 27 rotates, when the sensing end of the verification distance sensor 27 and the center point of the sensing block 28 are on the same horizontal line, when the distance between the verification distance sensor 27 and the sensing block 28 is the distance set by the wireless controller 14, the inner wall of the hexagonal sleeve 21 can achieve horizontal precise plugging with the locking bolt 4, and the wireless controller 14 turns off the transmission motor 24 at the same time.

[0044] The reduction motor 17 is started, and the reduction motor 17 drives the driving screw 16 to rotate inside the slide frame 15. The driving screw 16 carries the sleeve slider 18 to move right under the action of the thread transmission force. The sleeve slider 18 carries the support plate 25 to make the torque sensor 22 and the transmission motor 24 move right synchronously. The torque sensor 22 drives the rotating shaft 20 to move the hexagonal sleeve 21 to the right. The hexagonal sleeve 21 is sleeved on the outer wall of the locking bolt 4. The transmission motor 24 is started through the wireless controller 14. The transmission motor 24 drives the driving shaft 23 to rotate. The driving shaft 23 drives the sensing shaft of the torque sensor 22 to rotate. The sensing shaft of the torque sensor 22 drives the rotating shaft 20 to rotate inside the collar 19. The rotating shaft 20 carries the hexagonal sleeve 21 to rotate, and the hexagonal sleeve 21 drives the locking bolt 4 to rotate. The locking bolt 4 rotates and moves on the electric energy meter 2, and the end of the locking bolt 4 is squeezed on the wire head of the wiring harness 3. When the torque value of the rotating shaft 20 sensed by the torque sensor 22 is the same as the torque value set by the wireless controller 14, the transmission motor 24 is turned off through the wireless controller 14, so that the loose locking bolt 4 can be quickly docked and locked, which is convenient for later maintenance and saves time and effort.
