Description

Technical Field

[0001] This invention relates to the field of drainage system technology, and in particular to a controller protection device and an automatic early warning method for drainage system anomalies. Background Technology

[0002] In drainage systems, distribution cabinets and controllers are required to work together to provide early warning of abnormal water levels. When connecting the controller, the wires are usually connected to the controller's terminals, and then the controller is installed in the distribution cabinet.

[0003] During use, the wiring terminals of the current controller are generally exposed. Although they are placed in the distribution cabinet, dust can still enter the wiring terminals because the distribution cabinet needs ventilation, which affects the normal operation of the circuit (mainly because dust accumulation can easily generate static dust, which can cause short circuits or malfunctions in the circuit). Summary of the Invention

[0004] In view of the problem that the controller's wiring terminals are exposed in the prior art, making it easy for dust to enter the wiring terminals and affect the normal operation of the circuit, the present invention is proposed.

[0005] Therefore, the object of the present invention is to provide a controller protection device.

[0009] As a preferred embodiment of the controller protection device of the present invention, the receiving component includes two mounting boxes fixedly connected to the upper and lower ends of the controller. The mounting boxes are provided with multiple pairs of through holes that extend into the cavity. The mounting boxes are provided with multiple pairs of toothed plates that cooperate with the through holes, and the toothed plates mesh with gears.

[0010] As a preferred embodiment of the controller protection device of the present invention, the lifting assembly includes multiple pairs of circular openings disposed on the mounting box, each pair of circular openings having a cylinder slidably connected therein, the lower end of the cylinder being fixedly connected to a lifting plate, the lifting plate being elastically connected to the inner wall of the mounting box via a first spring, a T-shaped plate being fixedly connected to the lifting plate, and a pair of toothed plates being fixedly connected to the T-shaped plate.

[0011] As a preferred embodiment of the controller protection device of the present invention, the limiting component includes multiple support plates fixedly connected in the mounting box. Each support plate has two mounting openings, each with a bevel. The side wall of the right mounting opening has a latch that cooperates with the lifting plate. The lifting plate has a cut edge that cooperates with the bevel. Multiple stop plates are fixedly connected in the mounting box. The left side wall of the support plate is elastically connected to the stop plate through a second spring.

[0012] As a preferred embodiment of the controller protection device of the present invention, the toggle assembly includes a support box fixedly connected to the power distribution cabinet. The upper end of the support box is open, and a support opening is provided on the cylinder. A U-shaped plate is provided inside the support box, and a plurality of threaded holes are provided on the U-shaped plate. Each of the plurality of threaded holes is threaded with a screw that mates with the support opening.

[0013] As a preferred embodiment of the controller protection device of the present invention, the pumping assembly includes a first baffle plate disposed at the lower end of the cavity, a second baffle plate being slidably and sealingly connected to the side wall of the first baffle plate, a protective edge being fixedly connected to the first baffle plate, the second baffle plate being elastically connected to the inner wall of the cavity via a third spring, an inner groove being provided on the inner wall of the semi-circular opening, an arc-shaped airbag being provided in the inner groove, and the second baffle plate, the first baffle plate, and the inner wall of the cavity forming an air storage space, the air storage space being sealed and connected to the arc-shaped airbag via a pipe.

[0015] An automatic early warning method for drainage system anomalies includes: installing a controller in a control cabinet; connecting wires to the controller and protecting the controller terminals with a protective device; integrating a water pump, a water level detection device, the controller, and an alarm into the system; transmitting a signal to the system when the water level detection device detects an abnormal water level; and sending a signal to the controller to activate the alarm.

[0016] The beneficial effects of the controller protection device and drainage system abnormality automatic early warning method of the present invention are as follows: By setting up dustproof components, the terminals can be sealed after the wires are installed to prevent dust from entering. At the same time, the wires are also limited by the arc-shaped airbags to prevent them from loosening, thus ensuring the normal operation of the entire drainage abnormality automatic early warning system. This solves the problem that the controller's terminals are exposed and dust can easily enter the terminals, affecting the normal operation of the circuit. It achieves the effect of protecting the terminals and ensuring the normal operation of the drainage abnormality automatic early warning system. Attached Figure Description

Detailed Implementation

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Reference Figures 1 to 7This is the first embodiment of the present invention. This embodiment provides a controller protection device that can achieve the effects of dustproofing the terminal block 103 and preventing the wires from loosening. It includes a support component 100, including a distribution cabinet 101, a controller 102 disposed in the distribution cabinet 101, and a plurality of terminal blocks 103 disposed on the controller 102; a dustproof component 200, including a protective component 201 disposed on the upper side of the terminal block 103, a transmission component 202 disposed on the controller 102, a receiving component 203 disposed on the controller 102, a lifting component 204 disposed in the receiving component 203, a limiting component 205 disposed on the lifting component 204, and a toggle component 206 disposed in the distribution cabinet 101; and a sealing component 300, including a pumping component 301 disposed on the lifting component 204 and a locking component 302 disposed on the lifting component 204.

[0031] Specifically, the distribution cabinet 101 is rotatably connected to a door, and an installation rail is provided inside the distribution cabinet 101 to install the controller 102. The distribution cabinet 101 here is existing technology and will not be described in detail here. Multiple wiring terminals 103 are distributed at the upper and lower ends of the controller 102, and multiple bolts are provided on the controller 102 to fix the wires inside the wiring terminals 103.

[0032] Furthermore, the protective component 201 includes two outwardly expanding grooves 201a disposed at the opening of the terminal block 103. A rotating shaft 201b is rotatably connected within the two outwardly expanding grooves 201a. A sealing plate 201c is fixedly connected to the rotating shaft 201b. Each of the two sealing plates 201c is provided with a semi-circular opening 201d. The transmission component 202 includes a cavity 202a disposed on the controller 102. The cavity 202a communicates with the outwardly expanding grooves 201a through a connecting port 202b. The rotating shaft 201b communicates with the outwardly expanding grooves 201a through the connecting port 202b. 02b extends into the cavity 202a and is rotatably connected to the inner wall of the cavity 202a. A gear 202c is fixedly connected to the rotating shaft 201b. The housing assembly 203 includes two mounting boxes 203a fixedly connected to the upper and lower ends of the controller 102. The mounting box 203a is provided with multiple pairs of through holes 203b, which extend into the cavity 202a. The mounting box 203a is provided with multiple pairs of toothed plates 203c that cooperate with the through holes 203b. The toothed plates 203c mesh with the gears 202c.

[0033] The outer expansion groove 201a has an arc-shaped groove at its bottom to prevent the sealing plate 201c from abutting against the inner wall of the outer expansion groove 201a when the sealing plate 201c rotates. The effective number of downward teeth of the toothed plate 203c (i.e., the number of teeth that can mesh with the gear 202c) is one-quarter of that of the gear 202c, thereby driving the gear 202c to rotate 90°, so that the sealing plate 201c opens or closes.

[0034] Preferably, the lifting assembly 204 includes multiple pairs of circular openings 204a disposed on the mounting box 203a, each pair of circular openings 204a having a cylinder 204b slidably connected within it. A lifting plate 204c is fixedly connected to the lower end of each cylinder 204b. The lifting plate 204c is elastically connected to the inner wall of the mounting box 203a via a first spring 204d. A T-shaped plate 204e is fixedly connected to the lifting plate 204c, and a pair of toothed plates 203c are fixedly connected to the T-shaped plate 204e. The limiting assembly 205 includes components fixedly connected to the mounting box 203a. Multiple support plates 205a are provided inside 03a. Each support plate 205a has two mounting openings 205b. Each mounting opening 205b has a bevel 205c. The side wall of the right mounting opening 205b has a latch 205d that mates with the lifting plate 204c. The lifting plate 204c has a cut edge 205e that mates with the bevel 205c. Multiple stop plates 205f are fixedly connected inside the mounting box 203a. The left side wall of the support plate 205a is elastically connected to the stop plate 205f through a second spring 205g.

[0035] It should be noted that the thickness of the support plate 205a is less than the length of the lifting plate 204c. The first spring 204d is located behind the support plate 205a, so that the support plate 205a and the first spring 204d will not be jammed. The two mounting holes 205b are at the same height. The leftmost end of the latch 205d is collinear with the leftmost end of the inclined side 205c, so that when the lifting plate 204c pushes the support plate 205a at the left end, the lifting plate 204c can be reset.

[0036] In use, after wiring is completed at terminal 103, the sealing plate 201c is in the open state. Then, press the right-end cylinder 204b, causing it to move downwards. This downward movement of the cylinder 204b drives the lifting plate 204c downwards, which in turn drives the T-shaped plate 204e downwards, causing the two toothed plates 203c to move downwards. This downward movement of the toothed plates 203c drives the gear 202c to rotate, thereby rotating the shaft 201b and causing the sealing plate to open. Plate 201c changes from vertical to horizontal, sealing the upper end of terminal 103 to prevent dust. The inner wall of the semi-circular opening 201d abuts against the side wall of the wire, limiting its movement. When the right-end lifting plate 204c moves downward, the first spring 204d is compressed, and the tangent edge 205e on the lifting plate 204c engages with the inclined plate, causing the bearing plate 205a to move to the left. The second spring 205g is compressed. When the lifting plate 204c moves to be directly aligned with the latch 205d, the second spring 205g rebounds, causing the bearing plate 205a to... When 05a moves to the right, the latch 205d engages with the lifting plate 204c, preventing the lifting plate 204c from resetting and thus avoiding the resetting of the toothed plate 203c. This ensures the stability of the sealing plate 201c's limit position. When the sealing plate 201c needs to be opened, simply press the left-end cylinder 204b, causing it to move downwards. As the left-end cylinder 204b moves downwards, the tangent edge 205e on the left-end lifting plate 204c engages with the inclined edge 205c, pushing the bearing plate 205a to the left, thus opening the latch. When 205d is misaligned with the right lifting plate 204c, the right lifting plate 204c resets under the action of the first spring 204d, causing the T-shaped plate 204e to reset, the toothed plate 203c to reset, the gear 202c to reverse, and the rotating shaft 201b to reverse, thus opening the upper end of the terminal 103. Since the side wall of the mounting port 205b on the left end is not provided with a latch 205d, when the left cylinder 204b is released, the left lifting plate 204c can also reset under the action of the first spring 204d, thereby keeping the sealing plate 201c open.

[0037] In summary, when dustproofing the terminal block 103, simply press the cylinder 204b on the right end to automatically close the opening at the top of the terminal block 103, preventing dust from affecting the normal contact of the terminal block 103. At the same time, by setting a semi-circular opening 201d, the inner wall of the semi-circular opening 201d can abut against the side wall of the wire, preventing the wire from loosening.

[0038] Example 2

[0039] Reference Figure 7This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a toggle assembly 206 for the controller protection device, which solves the problem of how to toggle multiple cylinders 204b simultaneously. It includes a support box 206a fixedly connected to the power distribution cabinet 101. The upper end of the support box 206a is open. The cylinders 204b are provided with support openings 206b. A U-shaped plate 206c is provided inside the support box 206a. The U-shaped plate 206c is provided with multiple threaded holes 206d. Each of the multiple threaded holes 206d is threaded with a screw 206e that mates with the support opening 206b.

[0040] Specifically, the distance between the multiple threaded holes 206d is equal to the distance between two adjacent right (left) end cylinders 204b, so that they can be inserted into the support ports 206b of the multiple right (left) end cylinders 204b at the same time, so as to simultaneously move the multiple right (left) end cylinders 204b.

[0041] When using this device, if multiple right (left) end cylinders 204b need to be moved, simply remove the U-shaped plate 206c from the support box 206a, insert the multiple screws 206e on the U-shaped plate 206c into the support port 206b, and then press down on the U-shaped plate 206c to move multiple cylinders 204b. Since the screws 206e are threadedly connected to the threaded holes 206d, the length of the screws 206e extending to the outside of the U-shaped plate 206c can be adjusted, allowing you to choose to move one cylinder 204b or several cylinders 204b at a time, making it more flexible and convenient to use.

[0042] In summary, when multiple cylinders 204b need to be moved, the multiple screws 206e on the U-shaped plate 206c are inserted into the support ports 206b of the multiple cylinders 204b, and then pressed down. There is no need to press each cylinder 204b one by one, which makes it more convenient to use. At the same time, by adjusting the length of the screws 206e extending to the outside of the U-shaped plate 206c, one can choose to move one cylinder 204b or several cylinders 204b at a time, making it more flexible to use.

[0043] Example 3

[0044] Reference Figures 4-6This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a sealing component 300 for the controller protection device, solving the problem of how to further prevent dust from entering the wiring terminal 103. It includes a pump assembly 301, comprising a first baffle plate 301a disposed at the lower end of the cavity 202a, a second baffle plate 301b slidably connected to the side wall of the first baffle plate 301a, a protective edge 301c fixedly connected to the first baffle plate 301a, and the second baffle plate 301b elastically connected to the inner wall of the cavity 202a via a third spring 301d. The inner wall of the semi-circular opening 201d is provided with… The inner groove 301e contains an arc-shaped airbag 301f. The second baffle plate 301b, the first baffle plate 301a, and the inner wall of the cavity 202a are combined to form an air storage space. The air storage space is sealed and connected to the arc-shaped airbag 301f through a pipe 301g. The locking assembly 302 includes a turning plate 302a fixedly connected to the lifting plate 204c. An L-shaped limiting strip 302b is fixedly connected to the turning plate 302a. The rotating shaft 201b is located between the turning plate 302a and the limiting strip 302b. An anti-slip pad 302c is fixedly connected to the side wall opposite to the limiting strip 302b and the turning plate 302a.

[0045] Furthermore, the edge guard 301c prevents the second baffle 301b from detaching from the air storage space. When the arc-shaped airbag 301f is not inflated, it is completely retracted within the inner groove 301e, thus not affecting the sealing of the sealing plate 201c. The lengths of the turning plate 302a and the limiting strip 302b are less than the length of the toothed plate 203c. The toothed plate 203c has teeth only at its lower end and no teeth at its upper end. When all the teeth at the lower end of the toothed plate 203c are engaged with the gear 202c, the anti-slip pad 302c on the limiting strip 302b just contacts the limiting strip 302b.

[0046] During use, the downward movement of the lifting plate 204c drives the T-shaped plate 204e to move, causing the toothed plate 203c to move. Simultaneously, it also drives the turning plate 302a to move downward, causing the limiting strip 302b to move downward. When the non-toothed end of the toothed plate 203c is aligned with the gear 202c, the sealing plate 201c closes. At this time, the anti-slip pad 302c on the sidewall opposite the limiting strip 302b and the turning plate 302a is in contact with the rotating shaft 201b, preventing the rotating shaft 201b from rotating on its own, thus preventing the sealing plate 204e from rotating. 01c opens automatically, and at this time the lifting plate 204c continues to move downward, causing the turning plate 302a to continue to move downward. When the turning plate 302a moves downward, it can push the first shielding plate 301a downward, pumping the gas in the gas storage space into the arc-shaped airbag 301f through the pipe 301g, causing the airbag to collide and thus press the wires together, further preventing the wires in the terminal 103 from loosening, and filling the gaps to prevent dust from entering from the semi-circular opening 201d on the sealing plate 201c.

[0047] In summary, when the lifting plate 204c moves, it can also drive the turning plate 302a to push the first sealing plate 201c, pumping the gas in the gas storage space into the arc-shaped airbag 301f, causing the arc-shaped airbag 301f to expand, filling the gap between the semi-circular opening 201d and the wire, further preventing the wire in the terminal 103 from loosening, and allowing dust to enter from the semi-circular opening 201d on the sealing plate 201c.

[0048] Example 4

[0049] Unlike the previous embodiment, this embodiment provides an automatic early warning method for drainage system anomalies, including installing a controller 102 in a control cabinet; connecting wires to the controller 102 and protecting the controller 102's terminals 103 with a protective device; integrating a water pump, a water level detection device, the controller 102, and an alarm into the system; transmitting a signal to the system when the water level detection device detects an abnormal water level; and sending a signal to the controller 102 to activate the alarm. In use, it is necessary to calibrate the start-up and stop-down water levels of the hydropower station's sump, and determine the pump start-up / stop interval and start-stop interval based on the sump's inflow and the drainage pump's operating efficiency. The start-up / stop interval refers to the time required for the sump water level to rise from the stop-down level to the start-up level, and the start-stop interval refers to the time required for the drainage pump to pump the sump water level from the start-up level to the stop-down level. The alarm process for a drainage pump not starting for an extended period is as follows:

[0050] S1: Program initialization;

[0051] S2: Determine if a drainage pump is running. If yes, the process exits; otherwise, proceed to S3.

[0052] S3: Determine if the water level in the sump is at or below the pump stop level. If yes, proceed to S4; otherwise, exit the process.

[0053] S4: Start the stop-start interval timer (τstop), then proceed to S5;

[0054] S5: Obtain the target optimal stop-start interval (T), then proceed to S6;

[0055] S6: Determine whether the current stop-start interval time (τstop) is greater than the optimal stop-start interval target (T). If yes, proceed to S7; otherwise, proceed to S8.

[0056] S7: Output alarm: The drain pump has not been started for a long time, enter S10;

[0057] S8: Determine if the water level in the sump is at or above the pump start-up level. If yes, proceed to S9; otherwise, return to S5.

[0058] S9: Determine if a drain pump is running. If yes, proceed to S10; otherwise, return to S5.

[0059] S10: Set the stop-start interval timer (τstop) to zero, and proceed to S11;

[0060] S11: Process ends.

[0061] The procedure for "drainage pump operation timeout alarm" is as follows:

[0062] S1: Program initialization;

[0063] S2: Determine if the water level in the sump is at or above the pump start-up level. If yes, proceed to S3; otherwise, exit the process.

[0064] S3: Determine if a drainage pump is running. If yes, proceed to S4; otherwise, exit the process.

[0065] S4: Start start / stop interval timing (τ start), then proceed to S5;

[0066] S5: Obtain the target start-stop interval (T), then proceed to S6;

[0067] S6: Determine whether the current start-stop interval (τstart) is greater than the optimal start-stop interval target (T). If yes, proceed to S7; otherwise, proceed to S8.

[0068] S7: Output alarm: Drain pump operation timeout, proceed to S10;

[0069] S8: Determine if a drain pump is running. If not, proceed to S9; if yes, return to S5.

[0070] S9: Determine if the water level in the sump is at or below the pump stop level. If yes, proceed to S10; otherwise, return to S5.

[0071] S10: Set the start-stop interval (τstart) to zero and proceed to S11;

[0072] S11: Process ends.
