It is worth noting that the communicating pipe 15 can be also arranged on the container 2, the hydraulic oil in the container 2 enters the gear pump 12 along the communicating pipe 15 and a pipeline, and meanwhile, the number of the second box bodies 9 is conveniently increased or reduced, so that the device is suitable for different flow-limiting scales; the pipelines are all provided with one-way valves, so that hydraulic oil can only flow in one way; one side of the second box body 9, which is provided with the brake rod, can be designed into a concave form, so that the space can be saved, and the detention of personnel can be reduced; in use, the quick connectors 19 without pipelines on the communicating pipe 15 are all blocked by the inserted rods 18; the screw rod 3 and the nut 7 can be self-locked; the first hydraulic motor 4 and the second hydraulic motor 6 adopt hydraulic motors with self-locking function, and preferably adopt spring brakes to realize mechanical braking.

Before use, the first box body 1 is fixed at a proper position in the flow limiting area, then the plurality of second box bodies 9 are sequentially arranged from left to right, an oil inlet of the gear pump 12 in the second box body 9 on the right side of the first box body 1 is communicated with the container 2 and the first hydraulic motor 4 through pipelines to form a plurality of loops of 'the container 2-gear pump 12-the first hydraulic motor 4-the container 2', and any brake lever on the left side of the first box body 1 can rotate to enable the first hydraulic motor 4 to drive the screw rod 3 to rotate; an oil inlet of a gear pump 12 in a second box 9 on the right side of the first box 1 is communicated with the container 2 and the second hydraulic motor 6 through pipelines to form a plurality of loops of container 2-gear pump 12-second hydraulic motor 6-container 2, and the second hydraulic motor 6 can drive the long gear 5 to rotate by rotating any brake lever on the left side of the first box 1.

When the device is used, the distance between the nuts 7 at the two ends of the screw rod 3 is preset, and the long gear 5 can move rightwards in a shape if the screw rod 3 is fixed and does not rotate; suppose that the left side of the first box 1 is a tourist entrance, and the right side of the first box 1 is a tourist exit; in the initial state, the pinion 8 contacts with the nut 7 at the left end of the screw 3, when a tourist passes through the left side of the first box 1, the tourist holds the brake bar and pushes the brake bar to rotate, the brake bar rotates and drives the first chain wheel 11 to rotate through the universal coupling 14, the first chain wheel 11 drives the second chain wheel 13 to rotate through a chain, the second chain drives the hydraulic oil in the container 2 to be sent into the second hydraulic motor 6 through a pipeline through the gear pump 12, and finally enters the container 2, when the hydraulic oil passes through the second hydraulic motor 6, the second hydraulic motor 6 drives the long gear 5 to rotate, the long gear 5 drives the pinion 8 to rotate on the screw 3, because the pinion 8 is connected with the screw 3 through the screw thread, the pinion 8 also moves rightwards along the screw 3 when rotating, when the pinion 8 reaches the right end of the screw 3 and contacts with the nut 7 at the right side, the person in the scenic region reaches the peak of the quota, because nut 7 is spacing to pinion 8, so pinion 8 can not continue to rotate, causes long gear 5 also can not rotate, and long gear 5 does not change and makes second hydraulic motor 6 also not rotate, and hydraulic oil can not circulate in the loop this moment, and gear pump 12 also can not rotate, and first sprocket 11 and second sprocket 13 can not continue to rotate, finally make the brake lever can not rotate, realize preventing more personnel to continue to get into the scenic spot.

Normally, visitors in the scenic spot enter and exit, when going out through the second box body 9 on the right side, the visitors push the brake rod to rotate, then similarly to the above process, the gear pump 12 in the second box body 9 on the right side of the first box body 1 pumps hydraulic oil to the first hydraulic motor 4, the first hydraulic motor 4 rotates to drive the screw rod 3 to rotate, and since the pinion 8 is meshed with the long gear 5, assuming that the long gear 5 is fixed and does not rotate at the moment, the screw rod 3 rotates to enable the pinion 8 to move to the left through threads.

The invention has the advantages that:

1. the invention has wide application range, can limit the number of people in a specific area, and is suitable for places with an exit and an entrance at the same position and places with an entrance and an exit separated. The invention has a plurality of entrances and exits, the number of the entrances and exits can be increased or reduced according to the field condition, a plurality of persons can enter and exit simultaneously, the crowding is not easy to occur, the technology is accurate, and the people flow management and control of local areas of scenic spots are greatly facilitated.

2. According to the invention, hydraulic oil is adopted as a medium, the distance between the pinion 8 and the right nut 7 is used as a limiting condition, the hydraulic oil is converged by the gear pumps 12 so as to limit the total number of people in a local area of a scenic region, when the right end of the pinion 8 abuts against the right nut 7, the first chain wheels 11 and the second chain wheels 13 in all the second boxes 9 on the left side of the first box 1 cannot rotate, at the moment, the brake levers on the first boxes cannot rotate, and tourists are stopped outside the area to play a role in limiting the flow.

3. In the present invention, the two nuts 7 are provided on the screw 3, wherein the nut 7 on the left end is provided to prevent the long gear 5 from being disengaged from the pinion 8, and the nut 7 on the right side is provided to restrict the displacement of the pinion 8 in the horizontal direction. The distance between the pinion 8 and the right nut 7, the lead of the thread on the screw 3 and the transmission ratio between the long gear 5 and the pinion 8 can all influence the maximum number of people in the area, and the maximum number of people staying in the area can be effectively controlled; and the number of people who get into and the number of people who go out are related through hydraulic oil to the biggest number of people that can be real-time effectual control area is detained, safe and reliable.

4. The invention is suitable for various smaller fields and smaller areas in scenic spots, can be conveniently arranged at entrances and exits according to requirements, particularly indoor, small-sized glass platforms, annular trestles and high-altitude cableways, can effectively reduce the working pressure of workers, plays a role in limiting the flow and ensures the safety of tourists.
