Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet technology, specifically to an intelligent drainage control cabinet for coalbed methane wells. Background Technology

[0002] During the coalbed methane well drainage process, the intelligent drainage control cabinet is responsible for the centralized power supply and control of the downhole pump set, valves, and various sensors. Since coalbed methane wells are mostly located in remote areas, the control cabinet is exposed to wind, sand, rain, snow, and drastic temperature changes for a long time. At the same time, the electrical components inside the cabinet generate a lot of heat during continuous operation. If the heat dissipation is not good, it will lead to controller crashes, accelerated aging of circuit boards, and even fire hazards.

[0003] However, existing control cabinets have the following problems in practical applications: First, the ventilation slots on the side walls of the cabinet are mostly fixed open structures, which cannot be adjusted to open or close according to environmental needs. In windy and sandy weather, dust and sand particles can easily enter the cabinet, affecting the normal operation of electrical components. Second, the connection between the protective plate and the cabinet is mostly fixed with bolts or clips, which requires tools or effort to disassemble and maintain. Third, the existing exhaust structure is mostly of a single form, either exhausting upwards or downwards, and cannot flexibly select the exhaust direction according to the pipeline layout of the installation site, resulting in poor adaptability. Fourth, the protective plate lacks a reliable sliding guide and positioning structure during opening or closing, and is prone to shaking or jamming after long-term use, affecting the user experience.

[0004] Therefore, how to design a control cabinet with controllable opening and closing of ventilation slots, smooth sliding and reliable positioning of protective plates, and flexible replacement of exhaust direction according to site requirements has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent drainage and production control cabinet for coalbed methane wells, which has the advantages of high ventilation and heat dissipation efficiency, convenient disassembly and assembly of protective plates, replaceable exhaust structure and stable operation, thus solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A smart drainage control cabinet for coalbed methane wells includes a control cabinet body, two first support blocks fixedly connected to the lower end of the control cabinet body, a mounting groove opened at one end of the control cabinet body, a hollow protective plate slidably disposed on the inner wall of the mounting groove, a moving mechanism disposed at the lower end of the hollow protective plate, three sets of limiting mechanisms disposed on each side of the control cabinet body, magnets respectively locked in each set of limiting mechanisms, a circuit board fixedly connected to the inner wall of the control cabinet body, a controller disposed on the circuit board, support legs fixedly connected to the bottom surface of the inner wall of the control cabinet body, a cooling fan fixedly connected to the upper end of the support legs, three ventilation slots opened on each side of the control cabinet body, and a fixed... The system includes three first ventilation blocks connected to both sides of the hollow protective panel, and an exhaust assembly mounted on the hollow protective panel. Each set of limiting mechanisms includes two limiting strips, with the first ventilation block and a magnetic block simultaneously mounted between the opposite end faces of the two limiting strips in the same set. The first ventilation block is slidably positioned between the two limiting strips, and the magnetic block is fixedly clamped between the two limiting strips. The upper and lower end faces of the first ventilation block and the magnetic slider are respectively abutted against the opposite end faces of the two limiting strips. The first ventilation block has an air inlet slot on the side facing the center of the control cabinet, and an air outlet slot is formed on the inner wall of the air inlet slot. The ventilation slots and air inlet slots are connected one-to-one, and the air outlet slots are connected to the inner cavity of the hollow protective panel.

[0008] Preferably, the moving mechanism includes two fixed blocks, which are symmetrically fixed to the lower end of the hollow protective plate; the fixed blocks have a U-shaped structure, and rollers are rotatably installed on the inner walls of both sides of the fixed blocks.

[0009] It is worth noting that two fixing blocks are symmetrically arranged on both sides of the lower end of the hollow protective plate. Each fixing block is equipped with rollers on both sides of its inner wall. The outer peripheral wall of the rollers makes rolling contact with the bottom surface of the inner wall of the mounting groove. When the operator pushes and pulls the hollow protective plate, the rollers roll along the bottom surface of the mounting groove, converting sliding friction into rolling friction. This makes the pushing and pulling operation of the hollow protective plate easy and effortless, while reducing wear during long-term use.

[0010] Preferably, the exhaust end of the cooling fan is oriented towards the circuit board, and the ventilation slot runs through the side wall of the control cabinet and communicates with the internal cavity of the cabinet.

[0011] It is worth noting that the cooling fan is fixed to the upper end of the support leg, and its air outlet is directly facing the circuit board, which can force the low-temperature air at the bottom of the cabinet to the surface of the circuit board for cooling. The ventilation slots are opened on both sides of the control cabinet and are connected to the inner cavity of the cabinet. Driven by the cooling fan, the hot air inside the cabinet is discharged through the ventilation slots, and the cold air outside enters from the gaps or bottom of the cabinet to form a circulating cooling airflow.

[0012] Preferably, the hollow protective plate has a hollow cavity structure, and the two side walls of the hollow protective plate are provided with connecting holes, and the air outlet slot is connected to the inner cavity of the hollow protective plate through the connecting holes.

[0013] It is worth noting that the air outlet slot is located inside the first ventilation block. Its inner side is connected to the air inlet slot, and its outer side is connected to the inner cavity of the hollow protective plate through the connecting hole, forming a complete airflow channel from the inner cavity of the cabinet through the ventilation slot, air inlet slot, air outlet slot, connecting hole to the inner cavity of the hollow protective plate; the hot air is finally discharged outside the cabinet through the exhaust assembly, realizing the directional removal of heat from the cabinet.

[0014] Preferably, the exhaust assembly is an upper exhaust structure, including an upper groove extending through the upper part of the hollow protective plate, a second ventilation block fixedly connected to the inner wall of the upper groove, and a dust filter plate fixedly connected to the lower inner wall of the second ventilation block; the second ventilation block is an inverted U-shaped hollow structure, and the interior of the second ventilation block is connected to the interior of the hollow protective plate.

[0015] It is worth noting that the second ventilation block adopts an inverted U-shaped hollow structure with its air outlet facing downwards. Hot air flows upwards from the inner cavity of the hollow protective plate, passes through the inner cavity of the second ventilation block, and is discharged from the lower opening. The inverted U-shaped structure makes the exhaust outlet face downwards, which can effectively prevent rainwater and debris from falling into the hollow protective plate from the exhaust outlet. The dust filter plate is fixed to the lower inner wall of the second ventilation block to filter and intercept dust in the exhaust air.

[0016] Preferably, the exhaust assembly is a first lower exhaust structure, including a lower groove body that extends through the lower end of the hollow protective plate and a fixing plate that is fixedly connected to the inner wall of the lower groove body; the lower end of the fixing plate is provided with multiple filter holes that extend through to the inner cavity of the hollow protective plate.

[0017] It is worth noting that this preferred solution provides another specific implementation of the exhaust structure, which adopts a downward exhaust method with a fixed plate and filter holes; hot air is discharged directly downward from the inner cavity of the hollow protective plate through multiple filter holes, and the filter holes filter the dust in the airflow while exhausting; multiple filter holes are evenly distributed on the lower end face of the fixed plate, increasing the exhaust area and reducing airflow resistance.

[0018] Preferably, the exhaust assembly is a second lower exhaust structure, including a lower groove extending through the lower end of the hollow protective plate, a ventilation frame fixedly connected to the inner wall of the lower groove, and an inclined frame fixedly connected to the lower end of the ventilation frame; the interior of the ventilation frame communicates with the inner cavity of the hollow protective plate.

[0019] It is worth noting that this preferred solution provides another implementation method for the exhaust structure, which adopts a downward exhaust method with a ventilation frame and an inclined frame; the inclined frame is fixed to the lower end of the ventilation frame, and its air outlet is inclined towards the lower outside of the control cabinet, which can guide the exhaust hot air away from the cabinet and prevent hot air from accumulating at the bottom of the cabinet.

[0020] Preferably, the magnet block and the adjacent limiting strip are adhered to each other by magnetic attraction.

[0021] It is worth noting that the magnet is magnetically attached between the upper and lower limiting strips and can remain fixed in place without external force. When it is necessary to remove or replace the magnet, the operator only needs to apply external force to overcome the magnetic attraction to remove it from between the two limiting strips, making disassembly and assembly convenient.

[0022] Preferably, the magnet block in each set of limiting mechanisms is fixed, and the first ventilation block can slide horizontally between the two limiting strips.

[0023] It is worth noting that the magnet block and the first ventilation block are stacked in the same limiting mechanism along the height direction of the limiting strip. The two share the upper and lower opposing surfaces of the same set of limiting strips as guiding and contact surfaces. The magnet block is fixed and provides a lateral positioning reference for the first ventilation block. The first ventilation block slides horizontally along the limiting strip as the hollow protective plate moves, so as to align or misalign the ventilation slot with the air inlet slot and control the flow of ventilation air.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. This utility model allows the first ventilation block to slide horizontally along the limiting strip as the hollow protective plate moves, so that the air inlet slot and the ventilation slot are aligned or misaligned, thus realizing flexible control of the opening and closing of the ventilation slot. This solves the problem that the ventilation slot of the existing cabinet is fixed and open and cannot be adjusted according to environmental needs. Closing the ventilation slot in windy and sandy weather can effectively prevent dust from entering.

[0026] 2. This utility model uses a limiting strip to fit and limit the upper and lower end faces of the first ventilation block and the magnetic slider, and with the rolling support of the rollers in the moving mechanism along the bottom surface of the mounting groove, it realizes the smooth sliding and reliable guidance of the hollow protective plate, and solves the problems of inconvenient disassembly and assembly of existing protective plates and shaking and jamming after long-term use.

[0027] 3. This utility model, through the setting of three replaceable exhaust structures, allows for flexible selection of top exhaust, bottom exhaust with filter holes, or bottom exhaust with inclined frame according to the pipeline layout at the installation site, thus solving the problem of the single exhaust direction and poor adaptability of existing equipment;

[0028] 4. This utility model provides a fixed lateral positioning reference for the first ventilation block by magnetic adsorption and bonding between the magnet block and the limiting strip, ensuring that the first ventilation block always moves along the predetermined trajectory during the sliding process. At the same time, the magnet block is easy to disassemble and assemble, and easy to maintain. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0038] To address the problems of uncontrollable opening and closing of ventilation slots, inconvenient disassembly and assembly of protective plates, unidirectional exhaust direction, and unstable sliding guides in existing technologies, the following technical solution is proposed.

Each set of limiting mechanism includes two limiting strips 7.

The first ventilation block 8 is slidably set between the two limiting strips 7, and the magnetic block 9 is fixedly locked between the two limiting strips 7. The upper and lower end faces of the first ventilation block 8 and the magnetic block 9 are respectively attached to the opposite end faces of the two limiting strips 7. The first ventilation block 8 has an air inlet slot 15 on the side facing the center of the control cabinet 1. The inner wall of the air inlet slot 15 has an air outlet slot 16. The ventilation slot 14 and the air inlet slot 15 are connected one-to-one. The air outlet slot 16 is connected to the inner cavity of the hollow protective plate 4.

[0040] In this embodiment, specifically, the moving mechanism includes two fixed blocks 5, which are symmetrically fixedly connected to the lower end of the hollow protective plate 4. The fixed blocks 5 have a U-shaped structure, and rollers 6 are rotatably installed on the inner walls of both sides of the fixed blocks 5. The rollers 6 are made of metal or nylon, and their outer peripheral walls are in rolling contact with the bottom surface of the inner wall of the mounting groove 3.

[0041] In this embodiment, specifically, the exhaust end of the cooling fan 13 is positioned towards the circuit board 10, and the ventilation slot 14 penetrates the side wall of the control cabinet 1 and communicates with the internal cavity of the cabinet. The cooling fan 13 is an axial fan, and the support leg 12 supports the cooling fan 13 at a predetermined distance below the circuit board 10.

[0042] In this embodiment, specifically, the hollow protective plate 4 has a hollow cavity structure, and connecting holes are provided on both side walls of the hollow protective plate 4. The air outlet slot 16 is connected to the inner cavity of the hollow protective plate 4 through the connecting holes. The hollow protective plate 4 is a hollow rectangular plate formed by welding or bending metal sheet.

[0043] Example 1: In this example, the exhaust assembly is specifically an upper exhaust structure, including an upper groove 17 extending through the upper end of the hollow protective plate 4, a second ventilation block 18 fixedly connected to the inner wall of the upper groove 17, and a dust filter plate 19 fixedly connected to the lower inner wall of the second ventilation block 18; the second ventilation block 18 is an inverted U-shaped hollow structure, and the interior of the second ventilation block 18 is connected to the interior of the hollow protective plate 4. The dust filter plate 19 is a stainless steel wire mesh or fiber filter.

[0044] Example 2: In this example, specifically, the exhaust assembly is a first lower exhaust structure, including a lower groove 20 that penetrates the lower end of the hollow protective plate 4, and a fixing plate 21 fixedly connected to the inner wall of the lower groove 20; the lower end of the fixing plate 21 is provided with a plurality of filter holes 22, which extend into the inner cavity of the hollow protective plate 4. The plurality of filter holes 22 are evenly arranged along the lower end face of the fixing plate 21.

[0045] Example 3: In this example, specifically, the exhaust assembly is a second lower exhaust structure, including a lower groove 20 extending through the lower end of the hollow protective plate 4, a ventilation frame 23 fixedly connected to the inner wall of the lower groove 20, and an inclined frame 24 fixedly connected to the lower end of the ventilation frame 23; the interior of the ventilation frame 23 communicates with the inner cavity of the hollow protective plate 4. The inclined frame 24 is an inclined frame structure, with its air outlet facing the lower outer side of the control cabinet 1.

[0046] In this embodiment, specifically, the magnetic block 9 and the adjacent limiting strip 7 are magnetically attracted and attached together. The magnetic block 9 is a rectangular block made of permanent magnet, and the limiting strip 7 is a ferromagnetic metal strip.

[0047] In this embodiment, specifically, the magnet 9 in each set of limiting mechanisms is fixed, while the first ventilation block 8 can slide horizontally between the two limiting strips 7. The first ventilation block 8 is located between the magnet 9 and the side wall of the control cabinet 1.

[0048] In this embodiment, the controller 11 is specifically electrically connected to the cooling fan 13 and the external sampling equipment.

[0049] Working principle: During use, the controller 11 is linked with the external coalbed methane drainage equipment, and the cooling fan 13 is started synchronously. The cooling fan 13 blows air directly onto the circuit board 10, forcibly removing the heat generated by the circuit board 10 and the controller 11. The hot air inside the cabinet is blown by the cooling fan 13 and is discharged through the ventilation slots 14 on both sides of the control cabinet 1, and is sent into the air inlet slot 15 and air outlet slot 16 inside the first ventilation block 8. Then, it is sent into the hollow inner cavity of the hollow protective plate 4 through the connecting holes on the side wall of the hollow protective plate 4. The hot air entering the inner cavity of the hollow protective plate 4 is discharged to the outside by the exhaust assembly installed on the hollow protective plate 4, completing the whole machine's circulating heat dissipation.

[0050] The exhaust assembly can be implemented in three ways depending on the actual operating conditions:

[0051] If an upper exhaust structure is adopted, hot air passes through the upper trough 17 into the inner cavity of the inverted U-shaped second ventilation block 18, and then passes downward through the dust filter plate 19 to be discharged outward.

[0052] If the first bottom exhaust structure is adopted, the hot air passes downward through the fixed plate 21 inside the lower tank 20 and is discharged downward through a plurality of evenly opened filter holes 22;

[0053] If a second lower exhaust structure is adopted, hot air passes downward through the ventilation frame 23 inside the lower trough 20, is guided by the inclined frame 24, and is discharged to the lower outside of the control cabinet 1.

[0054] Throughout the entire operation, the opening or closing position of the hollow protective plate 4 is controlled by the limiting mechanisms on both sides. When the hollow protective plate 4 moves, the first ventilation block 8 slides horizontally between the two limiting strips 7, while the magnetic block 9 remains stationary. The first ventilation block 8, being made of iron, is attracted by the magnetic block 9. The magnetic force is used to attract and position the limiting strips 7, thereby maintaining the stability of the hollow protective plate 4 in the required working position.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
