When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0061] like Figures 1 to 14 As shown, the present application provides an integrally mounted gate accidental fall monitoring device, comprising a fixed portion 2, a movable portion 1 capable of moving relative to the fixed portion 2 in response to a gate 9 falling, and a detection portion 3 positioned on the fixed portion 2 and capable of being triggered by the movable portion 1 to generate a gate 4 accidental fall signal; wherein the movable portion 1 comprises a support rod 1-2 and a signal triggering unit 1-1, the support rod 1-2 being associated with the gate 9 to move downward in response to the gate 9 falling; the signal triggering unit 1-1 being coupled to the support rod 1-2 The support rod 1-2 is driven to move when the gate 9 falls; wherein the fixed part 2 includes a guide frame 2-1, a shock-absorbing base 2-2 and a guide sealing sleeve 2-3, the guide frame 2-1 is used to guide the movable part 1 to move downward; the shock-absorbing base 2-2 is used to buffer the movable part 1 to reduce the mechanical impact on the fixed part 2; the guide sealing sleeve 2-3 is used to guide the support rod 1-2; wherein the fixed part 2 is integrally mounted to the gate frame 7 to improve the installation efficiency and accuracy, and the movable part 1 can be movably assembled to the fixed part 2.

[0062] The fixed part 2 is pre-assembled to reduce the number of parts that need to be assembled and positioned on site, thereby improving the installation efficiency and accuracy of the monitoring device. In addition, both the fixed part 2 and the movable part 1 can be pre-assembled in the factory to further reduce the number of parts that need to be installed on site, thereby improving the installation efficiency of the monitoring device. In the tail gate tunnel of the pumped storage power station, the hydraulic hoist 6 is installed on the gate frame 7, and the hydraulic hoist 6 drives the gate 9 through the suspension shaft 8.

[0063] The fixing part 2 is installed on the gate frame 7 and is located inside the maintenance rack 5. The installation space is small and it is difficult to use auxiliary equipment. The overall size of the monitoring device of the patent is small, the weight is light, the installation is convenient and reliable, and it is more suitable for the installation site environment.

[0064] When the gate 9 is in full-open condition, the monitoring device starts monitoring; when the suspension shaft 8 or other components between the gate 9 and the hydraulic hoist 6 are accidentally broken, the support rod 1-2 falls with the gate 9 under the action of the signal trigger unit 1-1; during the falling process, the movable part 1 triggers the detection part 3, and the detection part 3 generates a falling signal. Among them, the signal trigger unit 1-1 stops moving after being buffered by the shock-absorbing base 2-2 at the end of the falling stroke; the gate frame 7 is the top cover of the gate slot of the gate 9.

[0065] The specific configuration of the signal trigger unit 1-1; refer to one embodiment, such as Figures 2 to 7 As shown, the signal trigger unit 1-1 includes a counterweight frame 1-1-2 and a plurality of counterweight blocks 1-1-1; the counterweight frame 1-1-2 has a placement cavity and is movably coupled to the guide frame 2-1; the plurality of counterweight blocks 1-1-1 are placed in the placement cavity of the counterweight frame 1-1-2, which facilitates the installation and increase and decrease of the counterweight blocks 1-1-1. Among them, except for the counterweight block 1-1-1, which needs to be adjusted, the rest of the movable part 1 and the fixed part 2 can be pre-assembled, and then the monitoring device can be assembled as a whole to the gate frame 7 to improve assembly efficiency and accuracy.

[0066] The specific configuration of the counterweight block 1-1-1; refer to one embodiment, as Figures 2 to 6 As shown, the counterweight 1-1-1 is a sheet-like structure; the number of counterweights 1-1-1 can be selected according to actual needs. The thickness of the counterweight 1-1-1 is 15mm-20mm; the weight of the counterweight 1-1-1 is 5kg-16kg. Multiple counterweights 1-1-1 are stacked; one of the two adjacent counterweights 1-1-1 has a positioning protrusion, and the other has a positioning concave portion that cooperates with the positioning protrusion, which can quickly install the counterweight 1-1-1 into the placement cavity and locate the position of the counterweight 1-1-1.

[0067] The specific configuration of the counterweight frame 1-1-2; refer to one embodiment, as shown in FIG. Figures 2 to 7As shown, the counterweight frame 1-1-2 includes a tray 1-1-2-2 and an anti-deflection frame 1-1-2-1. The tray 1-1-2-2 has a positioning protrusion, which is used to position the counterweight 1-1-1; the anti-deflection frame 1-1-2-1 is fixed to the tray 1-1-2-2 and forms a placement cavity with it to limit the rotation of the counterweight 1-1-1. When the counterweight 1-1-1 is placed on the tray 1-1-2-2, the groove on the counterweight 1-1-1 will cooperate with the positioning protrusion to locate the position of the counterweight 1-1-1; the contour of the counterweight 1-1-1 is roughly the same as the contour in the anti-deflection frame 1-1-2-1, so as to prevent the counterweight 1-1-1 from rotating. Among them, the tray 1-1-2-2 is fixedly connected to the anti-deflection frame 1-1-2-1 by bolts or welding.

[0068] In order to make the support rod 1-2 respond to the gate 9 falling; referring to one embodiment, as Figure 1 to Figure 2 As shown, the monitoring device also includes a bottom bracket 4, which is attached to the gate 9, and the support rod 1-2 can abut against the top of the bottom bracket 4; when the gate 9 falls accidentally, the bottom bracket 4 falls with the gate 9, the support rod 1-2 loses support, and the signal trigger unit 1-1 drives the support rod 1-2 to move downward. The bottom bracket 4 is roughly a rod-shaped structure; one end of the support rod 1-2 is connected to the signal trigger unit 1-1, and the other end passes through the guide sealing sleeve 2-3 and abuts against the top of the bottom bracket 4. Among them, the bottom bracket 4 is fixed to the top main beam of the gate 9 by welding or bolts.

[0069] The specific configuration of the shock-absorbing base 2-2; refer to one embodiment, such as Figures 2 to 4 and Figures 10 to 14 As shown, there is no strict restriction on the structure of the shock-absorbing base 2-2, as long as the shock-absorbing base 2-2 can buffer the mechanical impact generated by the fixing part 2. For example, the shock-absorbing base 2-2 is generally a plate-shaped structure, and is fixedly connected to the guide frame 2-1. The shock-absorbing base 2-2 is fixedly connected to the guide frame 2-1 by welding or bolts.

[0070] In this embodiment, if Figures 2 to 4 and Figures 10 to 14As shown, the shock-absorbing base 2-2 includes a chassis 2-2-1, a first buffer device 2-2-2 and a second buffer device 2-2-3. The chassis 2-2-1 is fixed to the guide frame 2-1. The first buffer device 2-2-2 and the second buffer device 2-2-3 constitute a secondary buffer system for the movable part 1. The signal trigger unit 1-1 is first buffered for a period of time by the first buffer device 2-2-2, and then the second buffer device 2-2-3 is added to buffer together, so as to achieve secondary buffering of the signal trigger unit 1-1 and reduce the impact of the signal trigger unit 1-1 on other components; in addition, the signal trigger unit 1-1 can be finally parked smoothly. The first buffer device 2-2-2 is one of a fluid buffer and an elastic buffer; the second buffer device 2-2-3 is one of a fluid buffer and an elastic buffer. The fluid buffer can be a hydraulic buffer or a gas buffer; the fluid buffer adopts the existing technology and will not be further explained here. The elastic buffer can be a rubber pad. The first buffer device 2-2-2 is a hydraulic buffer, and the second buffer device 2-2-3 is a rubber elastic pad. During the falling process of the movable part 1, the first buffer device 2-2-2 is configured to contact the movable part 1 before the second buffer device 2-2-3 to form a first-level buffer; the second buffer device 2-2-3 contacts the movable part 1 later to form a second-level buffer.

[0071] Specifically, the first buffer device 2-2-2 is higher than the second buffer device 2-2-3; the signal trigger unit 1-1 is first buffered by the first buffer device 2-2-2 for a certain distance, and then buffered by the first buffer device 2-2-2 and the second buffer device 2-2-3, so as to realize multi-level buffering of the signal trigger unit 1-1. The hydraulic buffer is installed on the chassis 2-2-1; the rubber elastic pad is annular, and the rubber elastic pad is sleeved on the outside of the support rod 1-2; there are multiple first buffer devices 2-2-2, and multiple first buffer devices 2-2-2 are arranged around the outer periphery of the support rod 1-2.

[0072] The specific configuration of the guide sealing sleeve 2-3; refer to one embodiment, as Figures 2 to 6 As shown, the guide sealing sleeve 2-3 is attached to the shock absorbing base 2-2 and can be fixed to the gate frame 7; the guide sealing sleeve 2-3 is sleeved on the outside of the support rod 1-2 to guide the support rod 1-2. The guide sealing sleeve 2-3 is installed on the gate frame 7 through the level adjustment member 2-3-7, and the level of the monitoring device can be quickly adjusted on site. Specifically, the gate frame 7 has a mounting hole, the guide sealing sleeve 2-3 is installed in the mounting hole, and then the level is adjusted by the level adjustment member 2-3-7, and finally fixed to the gate frame 7 by sealing welding and the like, which improves the installation efficiency and can improve the installation accuracy. Among them, the level adjustment member 2-3-7 is a level adjustment screw.

[0073] In this embodiment, if Figure 3 As shown, a guide belt 2-3-3 is provided between the guide sealing sleeve 2-3 and the support rod 1-2, and the guide belt 2-3-3 can guide the support rod 1-2. There is at least one guide belt 2-3-3, and each guide belt 2-3-3 is arranged in sequence along the axis of the sleeve 2-3-1; for example, there are two guide belts 2-3-3. A seal 2-3-4 is also provided between the guide sealing sleeve 2-3 and the support rod 1-2, and the seal 2-3-4 is located below the guide belt 2-3-3 to limit the outflow of the lubricant, thereby limiting the lubricant in the space above the seal 2-3-4. The seal 2-3-4 is a U-shaped sealing ring. When the monitoring device is in the installed state, the seal 2-3-4 is located below the guide belt 2-3-3. A scraper ring 2-3-5 is provided between the guide sealing sleeve 2-3 and the support rod 1-2. The scraper ring 2-3-5 can effectively reduce the probability of the support rod 1-2 getting stuck in the sleeve 2-3-1 due to dirt entering the sleeve 2-3-1.

Specifically, the base 2-3-2 and the gate frame 7 are fixed by sealing welding; the base 2-3-2 has a through hole, and the sleeve 2-3-1 extends into the through hole, and then is fixed to the base 2-3-2 by bolts or welding. Among them, a sealing ring 2-3-6 is arranged between the base 2-3-2 and the sleeve 2-3-1. The sleeve 2-3-1 and the chassis 2-2-1 are fixed by welding or bolts. Of course, in other embodiments, the sleeve 2-3-1 and the chassis 2-2-1 can also be arranged in one piece, so as to reduce the assembly difficulty between the sleeve 2-3-1 and the chassis 2-2-1, and strengthen the fixing strength between the sleeve 2-3-1 and the chassis 2-2-1.

[0075] In order to limit the moving path of the signal trigger unit 1-1; referring to one embodiment, as Figures 3 to 9As shown, the guide frame 2-1 has a guide groove, and the movable part 1 is attached with a guide block 1-1-4, which can be located in the guide groove and slide along the guide groove to limit the movement of the movable part 1. The guide block 1-1-4 can be fixed to the outside of the tray 1-1-2-2 by bolts or the like. There are four guide blocks 1-1-4, which are arranged in pairs on the diagonal sides of the counterweight frame 1-1-2 to prevent the movable part 1 from rotating. Specifically, the four guide blocks 1-1-4 are arranged at intervals around the outer periphery of the tray 1-1-2-2; the tray 1-1-2-2 is roughly rectangular in structure, and the tray 1-1-2-2 has four sides, and each guide block 1-1-4 is respectively located on the corresponding side of the tray 1-1-2-2, and is adjacent to the end of the side of the tray 1-1-2-2, and the guide blocks 1-1-4 are arranged in pairs on the diagonal sides of the counterweight frame 1-1-2.
