Description

Technical Field

[0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to a dust suction and cleaning equipment for a tunnel cable trench cover and a water trench cover. Background Art

[0002] Daily maintenance of power facilities is the core link to ensure the safe and stable operation of the power grid, among which the cleaning and maintenance of cable trenches are indispensable. As a key facility underground or in a tunnel, the cleanliness of the internal environment of the cable trench is directly related to the safe operation of the cable line. However, due to environmental factors, the top surface and the top two sides of the cable trench cover or ditch cover are prone to accumulate sand, dust and other debris. These debris not only affect the normal heat dissipation and ventilation of the cable, but may also cause physical damage to the cable, and even cause fire and other safety accidents in severe cases. Therefore, regular cleaning and maintenance of the cable trench and its surrounding areas is a necessary measure to ensure the safe operation of power facilities.

[0003] Most traditional cable trench dust removal equipment adopts a single suction port design, and requires operators to hold the dust head for cleaning. This operation method has many shortcomings. First, the operation range is limited, and only one side or a specific area of ​​the cable trench can be cleaned at a time. The operator needs to move the dust head frequently, which not only increases the complexity of the operation, but also greatly increases the time cost. Secondly, it is highly dependent on manual operation and has high requirements on the operator's skills and physical strength.

[0004] In addition to the above problems, traditional dust removal equipment also has obvious deficiencies in dust collection and treatment. Due to the single design of the dust suction port and the lack of an efficient filtration system, the dust collection effect is not ideal, and some dust and fine particles may be discharged into the environment with the air, causing secondary pollution. At the same time, the dust collection container usually has a limited capacity and requires frequent shutdown for replacement or cleaning, which undoubtedly further reduces the operating efficiency.

[0016] As described above, the dust collecting and cleaning equipment for the tunnel cable trench cover and the ditch cover of the present invention has at least the following beneficial effects: 1. The present invention drives the vacuum pump to move through a power device, generating a strong suction force, so that the first dust suction head and the second dust suction head can effectively suck dust and debris on the ground surface. This design ensures the efficiency and thoroughness of the dust suction work and improves the cleaning efficiency. The two dust suction heads (the first dust suction head and the second dust suction head) in the present invention are uniquely designed and can clean both sides of the channel at the same time. This feature significantly improves the efficiency of the cleaning operation and reduces the number of movements and time costs of the operator. The dust collection bucket adopts a detachable design, and the user can easily remove the dust collection bucket for cleaning and emptying, thereby simplifying the maintenance work. This design not only improves the user's convenience, but also helps to maintain the long-term and efficient operation of the dust collection mechanism. The first dust suction head and the second dust suction head are connected to the air inlet of the separation mechanism through a hose. This design enables the dust collection mechanism to flexibly adapt to different cleaning scenes and needs. The user can choose a suitable dust suction head according to actual needs, and adjust the dust suction angle and range through the hose, which improves the flexibility and adaptability of the dust collection operation.

[0017] 2. Through the automatic adjustment mechanism, the present invention realizes automatic adjustment and control of the first dust collector head and the second dust collector head. The swing drive assembly can drive the swing arm to rotate around the rotating shaft, so as to adjust the position and direction of the dust collector head. This design enables the dust collector head to be adaptively adjusted according to the width and shape of different channels, ensuring that the dust collector head maintains the best contact angle and distance with both sides of the channel, thereby improving the dust collection effect. The clamping claws on the automatic adjustment mechanism can firmly clamp the dust collector head to ensure that the dust collector head will not shake or fall off during the cleaning process. This not only improves the stability of the cleaning operation, but also enables the dust collector head to more accurately vacuum both sides of the channel, reducing the blind area of ​​cleaning and improving the cleaning quality and efficiency. The design of the automatic adjustment mechanism eliminates the need for the operator to manually adjust the position and angle of the dust collector head, thereby reducing the physical burden and labor intensity of the operator. The operator can remotely control and adjust the dust collector head by simply controlling the switch of the swing drive assembly and the telescopic length of the telescopic rod, thereby improving the convenience and comfort of the operation.

[0018] 3. The separation mechanism adopts a unique combination design of outer cylinder, conical inner cylinder, partition and dust-gas separation cylinder to ensure efficient dust-gas separation. The wind carrying dust enters the outer cylinder through the tangential air inlet to form a rotating airflow. Under the action of centrifugal force, the heavier dust particles are thrown to the inner wall of the conical inner cylinder and slide down along the inner wall to the dust collection bucket below. The lighter air enters the through hole in the center of the partition through the dust-gas separation cylinder and is finally discharged from the air outlet. This design not only improves the efficiency of dust-gas separation, but also effectively reduces the secondary lifting of dust in the dust collection bucket by air, maintaining the cleanliness of the dust collection bucket. Compared with the traditional filter, the separation efficiency is higher, and at the same time, it prevents the filter from being blocked and needs to be cleaned frequently. The conical inner cylinder is larger at the top and smaller at the bottom, so that the rotating dust-carrying wind speed increases in the gradually shrinking space, and the centrifugal force also increases accordingly. This design not only accelerates the separation of dust particles from air, but also improves the separation effect, allowing more dust particles to be effectively thrown into the inner wall of the conical inner cylinder and slide into the dust collection bucket. Due to the reasonable design of the airflow path inside the separation mechanism, the collision and turbulence of the airflow during the separation process are reduced, thereby reducing the generation of noise. At the same time, the solid structure of the conical inner cylinder and the partition also helps to reduce vibration and improve the stability and durability of the equipment.

[0019] 4. By introducing the second motor and the transmission assembly, the present invention realizes the active rotation of the dust and gas separation cylinder. The second motor is fixed on the partition, and drives the blades on the outer wall of the dust and gas separation cylinder to rotate through the transmission assembly. This design not only increases the rotation speed of the airflow in the dust and gas separation cylinder, but also increases the centrifugal force of the airflow, thereby further enhancing the dust and gas separation effect. The rotation of the blades not only accelerates the rotation of the airflow, but also allows the airflow to form a more stable rotating flow field in the dust and gas separation cylinder. This stable rotating flow field helps to more effectively throw dust particles toward the inner wall of the conical inner cylinder, and slide along the inner wall into the dust collecting bucket. At the same time, as the rotation speed of the airflow increases, the centrifugal force also increases, so that more tiny dust particles can be separated, improving the separation accuracy and efficiency.

[0024] The present invention drives the vacuum pump 4 to move through the power device 3, generating a strong suction force, so that the first dust suction head 801 and the second dust suction head 802 can effectively suck dust and debris on the ground surface. This design ensures the efficiency and thoroughness of the dust suction work and improves the cleaning efficiency. The two dust suction heads (the first dust suction head 801 and the second dust suction head 802) in the present invention are uniquely designed and can clean both sides of the channel 10 at the same time. This feature significantly improves the efficiency of the cleaning operation and reduces the number of movements and time cost of the operator. The dust collection bucket 7 adopts a detachable design, and the user can easily remove the dust collection bucket 7 for cleaning and emptying, thereby simplifying maintenance work. This design not only improves the user's convenience, but also helps to maintain the long-term and efficient operation of the dust collection mechanism. The first dust suction head 801 and the second dust suction head 802 are connected to the air inlet 603 of the separation mechanism through a hose 803.

[0025] In this embodiment, please refer to Figures 2 to 4 The tunnel cable trench cover and water ditch cover dust cleaning equipment also includes an automatic adjustment mechanism. Two groups of automatic adjustment mechanisms are respectively provided on both sides of the dust collecting bucket 7. The automatic adjustment mechanism includes a swing arm 202, a swing drive assembly and a telescopic rod 203. One end of the swing arm 202 is rotatably connected to the mobile base 1 through a rotating shaft. The other end of the swing arm 202 is fixed with a clamping claw 204. The first dust suction head 801 and the second dust suction head 802 are both rotatably provided with a rotating ring 804 at the connection with the hose 803. The rotating rings 804 of the first dust suction head 801 and the second dust suction head 802 are respectively clamped on the clamping claws 204 on the two groups of automatic adjustment mechanisms. The swing drive assembly is used to drive the swing arm 202 to rotate. One end of the telescopic rod 203 is hinged on the swing arm 202, and the other end of the telescopic rod 203 is hinged on the first dust suction head 801 or the second dust suction head 802. The telescopic rod 203 is an electric telescopic rod. A control panel 102 may be provided on the equipment placement box 101 for easy operation.

[0026] By setting up the automatic adjustment mechanism, the present invention realizes the automatic adjustment and control of the first dust collector head 801 and the second dust collector head 802. The swing drive assembly can drive the swing arm 202 to rotate around the rotating shaft, so as to adjust the position and direction of the dust collector head. This design enables the dust collector head to be adaptively adjusted according to the width and shape of different channels 10, ensuring that the dust collector head maintains the best contact angle and distance with both sides of the channel 10, thereby improving the dust collection effect. The clamping claw 204 on the automatic adjustment mechanism can firmly clamp the dust collector head and adjust the angle of the dust collector head through the telescopic rod 203; ensuring that the dust collector head will not shake or fall off during the cleaning process. This not only improves the stability of the cleaning operation, but also enables the dust collector head to more accurately vacuum both sides of the channel 10, reducing the cleaning blind area and improving the cleaning quality and efficiency. The design of the automatic adjustment mechanism eliminates the need for the operator to manually adjust the position and angle of the dust collector head, thereby reducing the physical burden and labor intensity of the operator. The operator can remotely control and adjust the vacuum cleaner head by simply controlling the switch of the swing drive assembly and the telescopic length of the telescopic rod 203, which improves the convenience and comfort of the operation. During operation, only one worker is needed to push the entire device forward, and both sides of the channel 10 can be cleaned. This improves efficiency. In this embodiment, please refer to Figures 1 to 6 The swing drive assembly includes a first motor 201, a first gear and a second gear; the first motor 201 is fixedly mounted on the mobile base 1, the first gear and the first motor 201 are coaxially fixedly connected, the second gear is fixedly connected to a rotating shaft fixedly mounted on the swing arm 202, and the first gear and the second gear are meshed with each other. The swing drive assembly can also be replaced by an electric telescopic rod. Through the setting of the swing assembly, the swing arm 202 can be freely controlled to swing, thereby adjusting the distance and position between the two vacuum heads to adapt to different environments.

[0027] In this embodiment, please refer to Figures 1 to 6The separation mechanism includes an outer cylinder 601, a conical inner cylinder 605 fixedly connected to the outer cylinder 601, a partition 606 dividing the outer cylinder 601 into two parts, an upper and lower part, and a dust and gas separation cylinder 607; the air inlet 603 of the separation mechanism is tangent to the inner wall of the outer cylinder 601, and the air inlet 603 is arranged between the conical inner cylinder 605 and the partition 606; a through hole 609 is opened in the center of the partition 606, and the dust and gas separation cylinder 607 is connected to the through hole 609; a sealing cover 604 is arranged on the top of the outer cylinder 601, the air outlet 602 is opened on the sealing cover 604, and the dust collecting bucket 7 is arranged directly below the conical inner cylinder 605. A layer of filter can be set at the bottom of the dust and gas separation cylinder 607, and an electric control valve can be set at the through hole 609 to control the opening and closing of the through hole 609. When a strong suction force is needed, the valve can be closed first, and the space on the partition can be evacuated by the vacuum pump 4, and then the electric control valve can be suddenly opened. At this time, a very strong suction force can be generated, thereby sucking away debris on the ground or in the gap of the lid.

[0028] The separation mechanism adopts a unique combination design of an outer cylinder 601, a conical inner cylinder 605, a partition 606 and a dust and gas separation cylinder 607 to ensure efficient dust and gas separation. The wind carrying dust enters the outer cylinder 601 through the tangential air inlet 603 to form a rotating airflow. Under the action of centrifugal force, the heavier dust particles are thrown to the inner wall of the conical inner cylinder 605 and slide along the inner wall to the dust collecting bucket 7 below. The lighter air enters the through hole 609 in the center of the partition 606 through the dust and gas separation cylinder 607 and is finally discharged from the air outlet 602. This design not only improves the efficiency of dust and gas separation, but also effectively reduces the secondary lifting of dust in the dust collecting bucket 7 by air, thereby maintaining the cleanliness of the dust collecting bucket 7. Compared with the use of traditional filter screens, the separation efficiency is higher, and at the same time, the filter screen is prevented from being blocked, resulting in frequent cleaning. The conical inner cylinder 605 is larger at the top and smaller at the bottom, so that the speed of the rotating dust-carrying wind increases in the gradually shrinking space, and the centrifugal force is also increased. This design not only accelerates the separation of dust particles from the air, but also improves the separation effect, so that more dust particles can be effectively thrown into the inner wall of the conical inner cylinder 605 and slide into the dust collection bucket 7. Due to the reasonable design of the airflow path inside the separation mechanism, the collision and turbulence of the airflow during the separation process are reduced, thereby reducing the generation of noise. At the same time, the solid structure of the conical inner cylinder 605 and the partition 606 also helps to reduce vibration and improve the stability and durability of the equipment.

[0029] In this embodiment, please refer to Figure 4 to Figure 5The separation mechanism also includes a second motor 608 and a transmission assembly. The second motor 608 is fixed on the partition 606. A plurality of blades 6071 are fixed on the outer wall surface of the dust and gas separation cylinder 607. The dust and gas separation cylinder 607 and the partition 606 are rotatably connected. The second motor 608 drives the dust and gas separation cylinder 607 to rotate through the transmission assembly.

[0030] By introducing the second motor 608 and the transmission assembly, the present invention realizes the active rotation of the dust and gas separation cylinder 607. The second motor 608 is fixed on the partition 606, and drives the blades 6071 on the outer wall surface of the dust and gas separation cylinder 607 to rotate through the transmission assembly. This design not only increases the rotation speed of the airflow in the dust and gas separation cylinder 607, but also increases the centrifugal force of the airflow, thereby further enhancing the effect of dust and gas separation. The rotation of the blade 6071 not only accelerates the rotation of the airflow, but also enables the airflow to form a more stable rotating flow field in the dust and gas separation cylinder 607. This stable rotating flow field helps to more effectively throw the dust particles to the inner wall of the conical inner cylinder 605, and slide along the inner wall into the dust collecting bucket 7. At the same time, as the rotation speed of the airflow increases, the centrifugal force is also increased, so that more tiny dust particles can be separated, and the separation accuracy and efficiency are improved.

[0031] In this embodiment, please refer to Figure 4 to Figure 5 The transmission assembly includes a third gear and a gear ring, the gear ring is fixedly connected to the dust and gas separation cylinder 607 coaxially, the third gear is fixedly connected to the output shaft of the second motor 608 coaxially, and the third gear and the gear ring are meshed with each other. The transmission assembly can also be a chain or belt transmission device.
