Description

Technical Field

[0001] This invention relates to a circuit control box, specifically a control box for hydraulic gates. Background Technology

[0002] A control box is an electrical control device widely used in various scenarios such as commerce and industry. It is mainly used to centrally install various control components to achieve centralized control of electrical appliances.

[0003] Due to the special nature of their environment, hydropower stations have more stringent requirements for electrical control boxes, mainly in the following aspects: First, hydropower stations are located in rivers for a long time, with a lot of water vapor and high humidity. Long-term opening and closing can easily lead to short circuit faults and shorten the service life of the circuits due to water vapor intrusion. Second, without protective measures, long-term opening and closing can also lead to dust accumulation and insect intrusion, which can further affect the normal use of control components.

[0004] To address the aforementioned problems, the existing technology proposes the following technical solution: Chinese Patent Application No. 202220547828.9 discloses an intelligent integrated gate for a dual-control control box for water and electricity. This method involves adding an external switch to the surface of the box, which is connected to an internal switch within the box via a linkage (lever). This allows the external switch to control the opening and closing of the internal switch without opening the box, thus preventing the intrusion of harmful substances such as dust and insects and protecting circuit safety. However, this existing technology has the following drawbacks: 1. Poor stability. The linkage (number 15) is connected to the switch via a hinged rod (number 16). If the manufacturing or assembly precision is insufficient, transmission gaps can easily occur, leading to asynchronous operation between the external and internal switches. In addition, long, narrow components such as hinge rods and connecting rods have a certain degree of elasticity. During the force transmission process, factors such as elasticity, installation gaps, and sway may cause the force of the external switch to be unable to be fully transmitted to the internal switch; 2. This connection method also carries the risk of connection detachment; 3. The lever mechanism is located in the center of the control box. Once a fault occurs (such as connecting rod deformation or hinge point breakage), the entire assembly needs to be disassembled for repair, resulting in high maintenance costs. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a dedicated control box for hydraulic gates. This device effectively isolates control components from the outside environment, enhances waterproof, dustproof, and insect-proof effects, and also improves operational stability, facilitates maintenance, and reduces maintenance costs. The specific solution is as follows.

[0006] A special control box for hydraulic gates includes a box body comprising a front plate, a rear plate, an upper plate, a lower plate, and left and right side plates. A controller is fixed on the rear plate, and the controller has an internal switch. The key feature is that the front plate has a through hole into which an external switch is embedded. The external switch includes an external lever, an internal lever, and a roller seat. The external lever and internal lever are respectively located on the front and rear sides of the roller seat, and the roller seat is fixed in the through hole by a shaft. Pulleys are fixed at four positions inside the box: front upper, front lower, rear upper, and rear lower. The pulleys, the internal switch, and the external switch (internal lever) are located on the same plane. A pull rope passes around the pulleys to connect the internal switch and the external switch (internal lever).

[0007] The through hole is circular, the roller seat is spherical, and a sealing ring is provided between the through hole and the roller seat.

[0008] The pulley includes a roller and a roller seat. The roller seat is T-shaped. A corresponding slot shell that matches the shape of the roller seat is provided on the inner side of the housing. The roller seat is embedded in the slot shell. The slot shell has a positioning hole, and the roller seat is fixed in the positioning hole position by screws.

[0009] The method of fixing the pull rope to the inner switch is as follows: the inner switch has a wire hole, the pull rope passes through the wire hole and is wrapped around several times, or the pull rope passes through the wire hole and is knotted.

[0010] The method of fixing the pull cord to the external switch is that the end of the inner lever is provided with a wire hole, and the two ends of the pull cord pass through the wire hole and are locked by the rope lock.

[0011] The rope lock includes a lock seat and a U-shaped lock rod. The two legs of the lock rod are threaded, and the two legs of the lock rod pass through the lock seat and are provided with nuts on the outside. An adjustable gap is formed between the lock rod and the lock seat for locking the pull rope.

[0012] The external switch (one), controller (one), pulleys (four), and pull rope (one) constitute a control unit, and multiple control units are arranged side by side inside the box.

[0013] The front panel is equipped with an observation window, and each control unit is equipped with an identification plate.

[0014] The rear end of the right side panel of the box is hinged to the box body, and the front end of the right side panel is provided with a locking buckle that cooperates with and locks the box body.

[0015] The box is equipped with a door, with a space between the door and the front panel. The door is made of transparent or mesh material.

[0016] In the above scheme, directional terms such as front, back, left, and right are based on appended... Figure 1 The indicated direction refers to the direction in which the front panel is located. The directional term is used solely for the convenience of describing and understanding this technical solution.

[0017] In summary, compared with existing technologies, this technical solution not only achieves waterproof, dustproof, and insect-proof effects, but also provides more stable force transmission, more synchronized internal and external switching, and easier maintenance with reduced maintenance costs, making it very suitable for use in environments such as hydropower stations.

[0024] Example 1, see appendix Figure 1-4 A special control box for hydraulic gates includes a box body 1, which comprises a front plate 1-4, a rear plate, an upper plate, a lower plate, and left and right side plates 1-3. A controller 6 is fixed on the rear plate, and the controller is equipped with an inner switch 6-1. The front plate has a through hole into which an outer switch 3 is embedded. The outer switch includes an outer lever 3-1, an inner lever 3-3, and a roller seat 3-2. The outer lever and inner lever are respectively located on the front and rear sides of the roller seat, and the roller seat is fixed in the through hole by a shaft 11. Pulleys 7 are fixed at four positions inside the box: front upper, front lower, rear upper, and rear lower. The pulleys, the inner switch, and the outer switch (inner lever) are located on the same plane. A pull rope 5 passes around the pulleys to connect the inner switch and the outer switch (inner lever).

[0025] The through hole is circular, the roller seat is spherical, and a sealing ring 10 is provided between the through hole and the roller seat.

[0026] The pulley 7 includes a roller and a roller seat. The roller seat is T-shaped. A corresponding slot shell 9 is provided on the inner side of the box to match the shape of the roller seat. The roller seat is embedded in the slot shell. The slot shell has a positioning hole 9-1, and the roller seat is fixed in the positioning hole position by screws.

[0027] The method of fixing the pull rope to the inner switch is as follows: the inner switch has a wire hole, the pull rope passes through the wire hole and is wrapped around several times, or the pull rope passes through the wire hole and is knotted.

[0028] The method of fixing the pull rope to the external switch is that the end of the inner lever is provided with a wire hole 3-4, and the two ends of the pull rope pass through the wire hole and are locked by the rope lock 8.

[0029] The rope lock 8 includes a lock seat 8-2 and a U-shaped lock rod 8-1. The two legs of the lock rod are threaded, and the two legs of the lock rod pass through the lock seat and are provided with nuts 8-3 on the outside. An adjustable gap is formed between the lock rod and the lock seat for locking the pull rope.

[0030] The external switch (one), controller (one), pulleys (four), and pull rope (one) constitute a control unit, and multiple control units are arranged side by side inside the box.

[0031] The front panel is provided with an observation window 2, and each control unit is provided with an identification plate 4.

[0032] The right side panel of the enclosure is hinged to the enclosure at its rear end, and its front end is fitted with a locking buckle that engages with and locks the enclosure at its front end. A sealing strip can be added to the edge of the side panel to enhance sealing.

[0033] The box body is equipped with doors 1-2, with a space between the doors and the front panel, and the doors are made of transparent material.

[0034] The principle behind this embodiment is:

[0035] As attached Figure 2 As shown, when the technician moves the outer switch upward, the outer lever moves up and the inner lever moves down. The end of the inner lever pulls the pull rope downward, and the pull rope rotates counterclockwise. Under the transmission of force, the pull rope drives the inner switch behind it to move upward, and the controller is turned on. Conversely, when the technician moves the switch downward, the inner lever moves up and the pull rope rotates clockwise, causing the pull rope to pull the inner switch downward, and the controller is turned off.

[0036] Further explanation of this technical solution:

[0037] This technical solution enhances waterproofing, dustproofing, and insect prevention: The enclosure is typically closed, with the front, back, top, bottom, and side panels forming a relatively enclosed space. Without opening the enclosure, technicians can control the internal controller via an external switch on the front panel. This significantly reduces and prevents moisture, dust, insects, and other harmful substances from entering the enclosure, minimizing circuit malfunctions, ensuring proper functioning of control components, and extending equipment lifespan. To further improve dryness, dehumidifying bags can also be placed inside the enclosure.

[0038] This technical solution facilitates maintenance: external switches, controllers, pull ropes, and pulleys can be maintained by opening the side panel. Each control unit is independent, so maintaining one control unit does not affect adjacent units. Furthermore, the components are located around the perimeter of the enclosure, with ample space in the center for easy access and to accommodate tools such as screwdrivers and wrenches. Therefore, this achieves the technical effect of low maintenance costs and ease of maintenance.

[0039] This technical solution offers good stability: the pull rope can be made of materials such as nylon, polyester fiber, or polypropylene. On the one hand, these materials have good insulation properties, improving safety; on the other hand, these materials are sturdy, durable, and almost inelastic, which can better transmit the force of the external switch to the internal switch without attenuation, thus improving stability.

[0040] There are several options for connecting and fixing the pull rope to the external and internal switches, such as increasing the number of wrapping turns, knotting, or using a rope lock. This embodiment uses an increased number of wrapping turns at the internal switch and a rope lock at the external switch. The purpose is to reduce the number of joints and maintain the integrity of the pull rope, with only one pull rope used per control unit. Technicians can place the joint at either the internal or external switch, achieving the same technical effect. The principle of the rope clamp is that using a sleeve wrench to rotate the nut controls the lock seat to move closer to or away from the lock rod, thereby achieving the locking / unlocking of the pull rope.

[0041] Because it has a door, the external switches can be prevented from being accidentally touched. The door is made of transparent or mesh material, making it easy to observe the status of the external switches. The label helps to distinguish the different circuits controlled by each external switch.

[0042] In summary, compared with existing technologies, this technical solution not only achieves waterproof, dustproof, and insect-proof effects, but also provides more stable force transmission, more synchronized internal and external switching, and facilitates maintenance while reducing maintenance costs.
