Description

Technical Field

[0001] The utility model relates to the field of gate hoisting of a hydropower station, in particular to an electromagnetic automatic hanging and dropping beam of a hydropower station. Background Art

[0002] The water gate warehouse usually stores gates. During the hoisting process of the hydropower station gate, a crane is needed to connect the lifting ears on the beam through a movable pulley. Then when the gate is hoisted to the underwater gate slot, a hooking and unhooking beam is needed to be used to hook and unhook the gate underwater. The upper end of the automatic hooking and unhooking beam is connected to the hoisting equipment. During the process, the beam is gradually lowered, and then the lower end of the beam is unhooked from the gate at the designated underwater position to complete the lifting action.

[0003] At present, there are two types of automatic hanging and disengaging beams for detaching and disengaging gates underwater: mechanical automatic hanging and disengaging beams and hydraulic automatic hanging and disengaging beams. The characteristic of the mechanical automatic hanging and disengaging beam is that when the gate is lowered to the bottom in the water, the mechanical automatic hanging and disengaging beam continues to be lowered to produce automatic unhooking, thereby completing the whole process of lowering the gate. However, during use, when the gate is stuck in the water, if the operator still lowers the gate to the bottom and continues to lower the mechanical automatic hanging and disengaging beam to produce automatic unhooking, the gate is completely disengaged from the mechanical automatic hanging and disengaging beam, but the gate is still stuck in the gate slot and cannot be moved up and down, thus causing an operation accident. In comparison, the hydraulic automatic hanging and disengaging beam It is safer to use a hydraulic automatic hook and detach beam. However, the most commonly used hydraulic automatic hook and detach beam is hydraulically controlled. The rotation of the motor drives the hydraulic pump station to realize the insertion and retraction of the hook and detach beam pin, thereby realizing the connection and disconnection with the gate. However, during use, the hydraulic automatic hook and detach beam requires the motor to operate underwater, and a signal is required to display the status of the pin in multiple directions. It has many parts and cables need to be followed underwater for power supply and signal transmission, resulting in a high failure rate. In addition, the pin needs to be accurately aligned with the gate underwater, which takes a long time, further leading to low efficiency of the gate connection process. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an electromagnetic automatic hanging and detaching beam device for a hydropower station, which solves the problem of low gate connection efficiency caused by the pin-threading and pin-retracting links that must be used in the traditional technology.

[0005] According to the technical solution of the utility model, an electromagnetic automatic hanging and detaching beam device of a hydropower station includes a beam body and a gate, a lifting lug is installed on the upper part of the beam body, a cavity is arranged inside the beam body, a partition is arranged in the cavity to separate the beam body from top to bottom, a sealed cabin located at the upper part and an installation cabin located at the lower part are arranged in the cavity, an electromagnetic control system is installed in the sealed cabin, an elastic force-bearing mechanism is arranged in the installation cabin, a plurality of electromagnetic suction cups are connected to the lower part of the elastic force-bearing mechanism, and the bottom of the installation cabin is open to allow the electromagnetic suction cups to expose the installation cabin.

[0006] The technical principle of the utility model is as follows: the gate needs to be hoisted from the water gate warehouse to the underwater gate slot, the movable pulley end of the crane is connected to the lifting ear on the beam body, and the electromagnetic suction cup is in a demagnetized state at the same time, and then the crane moves the beam body horizontally and vertically into the gate warehouse, sits on the gate, operates the electromagnetic control system, puts the electromagnetic suction cup in a magnetized state, sucks the gate, the crane lifts the beam body together with the gate to leave the gate warehouse, moves horizontally and vertically into the gate slot, the crane lowers the beam body together with the gate until it is in place at the bottom of the gate slot, and finally operates the electromagnetic control system to put the electromagnetic suction cup in a demagnetized state, thereby disengaging the gate and completing the operation of the gate from the water gate warehouse to the underwater gate slot. In this way, the problem of low gate connection efficiency caused by the pin-threading and pin-retracting links that must be used in traditional technologies is solved.

[0007] Compared with the prior art, the utility model has the following beneficial effects: by utilizing the electromagnetic magnetic pole conversion principle to magnetically attract or release the gate to achieve gate lifting, the hanging and detaching mode of the horizontal pin of the hydraulic automatic hanging and detaching beam is completely changed, thereby reducing the failure rate, and solving the problem of low gate connection efficiency caused by the pin-threading and pin-removal link that must be used in traditional technology, further producing the beneficial effect of improving the gate connection efficiency.

[0015] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] As shown in the following figures, the embodiments of the utility model propose an electromagnetic automatic hanging and detaching beam device for a hydropower station, which includes a beam body 1 and a gate 9, a lifting lug 101 is installed on the upper part of the beam body 1, a cavity is arranged inside the beam body 1, a partition 2 is arranged in the cavity to separate the upper and lower parts thereof, a sealed cabin 10 located at the upper part thereof and an installation cabin 7 located at the lower part thereof are arranged in the cavity, a battery pack 4 and an electromagnetic control system 5 electrically connected to each other are installed in the sealed cabin 10, an elastic force-bearing mechanism 6 is arranged in the installation cabin 7, a plurality of electromagnetic suction cups 3 are connected to the lower part of the elastic force-bearing mechanism 6, and the bottom of the installation cabin 7 is open to allow the electromagnetic suction cups 3 to expose the installation cabin 7.

[0017] Specific operation process: It is necessary to lift the gate 9 from the water gate warehouse to the underwater gate slot. The crane's movable pulley connects the lifting ear 101 on the beam body 1 to make the electromagnetic suction cup 3 in a demagnetized state. The crane moves the beam body 1 horizontally and vertically into the gate warehouse and sits on the gate 9. The electromagnetic control system 5 is operated to make the electromagnetic suction cup 3 in a magnetized state to attract the gate 9. The crane lifts the beam body 1 together with the gate 9 to leave the gate warehouse, moves horizontally and vertically into the gate slot of the gate 9, and lowers the beam body 1 together with the gate 9 until the bottom of the gate slot is in place. Operation The electromagnetic control system 5 is controlled to put the electromagnetic suction cup 3 in a demagnetized state, thereby disengaging the gate 9 and completing the operation of the gate 9 from the water gate reservoir to the underwater gate slot. The gate 9 is lifted by magnetically attracting or releasing the gate 9 according to the principle of electromagnetic magnetic pole conversion, which completely changes the hanging and detaching mode of the horizontal pin of the hydraulic automatic hanging and detaching beam, thereby reducing the failure rate, solving the problem of low connection efficiency of the gate 9 caused by the pin-removing link that must be used in traditional technologies, and further producing a beneficial effect of improving the connection efficiency of the gate 9.

[0018] like Figure 2 As shown, as a preferred technical solution of the utility model, the elastic force-bearing mechanism 6 includes a pressure-bearing steel plate 8, and the pressure-bearing steel plate 8 is fixedly connected to the inner side of the bottom of the installation cabin 7. In this solution, the pressure-bearing steel plate 8 can be behind the magnetic suction gate 9 to avoid excessive pressure from crushing or collapsing the bottom of the installation cabin 7, thereby increasing the pressure-bearing capacity of the bottom of the installation cabin 7.

[0019] like Figure 2 , 5As shown, as a preferred technical solution of the utility model, the elastic force-bearing mechanism 6 also includes a suspension rod 602, a nut 603 and a spring 601. The upper part of the suspension rod 602 extends into the installation cabin 7, and the lower part thereof is fixedly connected to the pressure-bearing steel plate 8. The spring 601 is sleeved on the upper end of the suspension rod 602, and the nut 603 is fixedly connected to the top of the suspension rod 602. In this solution, the pressure generated by the magnetic pole magnetic attraction closing gate 9 is transmitted to the spring 601 through the pressure-bearing steel plate 8, and the spring 601 transmits the force to the structure. The elastic force-bearing mechanism 6 can form a flexible contact between the electromagnetic magnetic disk 3 and the gate 9, which can ensure that the electromagnetic suction cup 3 is uniformly adsorbed on the top surface of the gate 9, avoiding the uneven adsorption surface due to deformation of the gate 9 and other reasons, thereby reducing the adsorption effect of the electromagnetic suction cup 3.

In this solution, the fixed washer is used to limit the magnetic attraction height of the electromagnetic chuck 3 during the magnetic attraction process when the spring 601 contracts and rises.

[0021] like Figure 4 As shown, as a preferred technical solution of the utility model, the top of the gate 9 is provided with two horizontal and vertical raised parts, and the middle position of the raised part is formed with a positioning groove 11. The raised part in this solution is to ensure that the electromagnetic suction cup 3 can more easily find the magnetic suction position of the gate 9.

[0022] like Figure 4 As shown, as a preferred technical solution of the utility model, the positioning groove 11 is square, and the length and width just correspond to the bottom size of the electromagnetic suction cup 3. In this solution, the recessed depth and length and width of the positioning groove 11 just correspond to the height and length and width of the electromagnetic suction cup 3, which facilitates the electromagnetic suction cup 3 to locate the magnetic suction interface of the gate 9.

In this solution, the battery sealed cabin 103 and the control system installation cabin 102 are separated on the one hand to avoid the overlap and intersection of the lines connected to the battery pack 4 and the electromagnetic control system 5 lines, thereby causing a malfunction, and on the other hand, the replacement of the battery pack 4 can also be more convenient.

[0024] like Figure 3As shown, as a preferred technical solution of the utility model, the battery sealed cabin 103 is located in the middle of the sealed cabin 10, and two control system installation cabins 102 are provided, symmetrically arranged on both sides of the battery sealed cabin 103, and two door slot supports 104 are provided at the farthest symmetrical ends on both sides of the control system installation cabin 102. The symmetrical design in this solution can ensure that the lines on both sides can also be arranged symmetrically, which increases the rationality of the line arrangement. At the same time, the batteries are arranged on both sides of the battery sealed cabin 103, which can eliminate the power supply cables, making it highly reliable. On the other hand, the door slot supports 104 on both sides facilitate the installation of the lifting lugs 101.
