Description

Technical Field

[0001] The present invention relates to the field of fence protection in agricultural and pastoral areas, and in particular to an automatic energy-saving fence door for vehicle entry and exit. Background Art

[0002] The Inner Mongolia Autonomous Region has vast grasslands dotted with many wind farms, with each farm having at least twenty or even hundreds of wind turbines. Since the use of the grasslands is controlled by local herders, the wind turbines at each wind farm are divided into several areas by each herder with wire mesh fences, making it easier for herders to graze their own cattle and sheep. At the point where the maintenance road used by power plant personnel passes through the wire mesh fence, herders have installed simple fence gates, which are hung with hooks after closing to prevent the cattle and sheep from being blown away by the wind. The installation of wire mesh fences is beneficial for herders to manage cattle and sheep, but it brings trouble to the travel of wind farm maintenance personnel: when inspecting and repairing wind turbines, personnel need to get off the vehicle to open and close the door when the vehicle passes, which is cumbersome and time-consuming. Automatic switching equipment in the existing technology requires the installation of corresponding control circuits and drive devices, and the system is complex and requires electric drive. Summary of the Invention

[0003] In order to solve this problem, an automatic energy-saving fence door for vehicle entry and exit is provided.

[0004] An automatic energy-saving fence gate for vehicle entry and exit, comprising a center post and two side posts, characterized in that a guide groove is provided between the center post and the side posts, with the left and right sides each having a respective guide groove; a rotation axis is provided at the proximal end of the guide groove, which cooperates with a rotation axis seat mounted on the upper end of the center post; the distal end of the guide groove is connected to the side posts via an elastic damping member; the guide groove is a slender beam, which is used to accommodate the left and right sliding of a mesh door body inside; a wheel rolling strip is connected to the middle of the guide groove, and the wheel rolling strip is located on both sides of the guide groove;

[0005] When the far end of the guide groove is at a high position, the door bodies on both sides slide toward the center to close the fence door;

[0006] The vehicle wheels move forward and press the wheel rolling strip, which moves downward, driving the guide groove to rotate downward, and the far end of the guide groove drops from a high position to a low position. Under the action of gravity, the gate bodies on both sides slide freely from the center to the two ends, opening the fence gate;

[0007] The middle of the guide groove is provided with a load-bearing member, which is arranged on the left and right sides of the middle of the guide groove. The base of the load-bearing member is fixedly installed on the guide groove, and the load-bearing member is connected to the movable end of the wheel rolling bar.

[0008] Advantages of the technical solution of the present invention:

[0009] The simple fence gate is replaced with an automatic energy-saving mesh fence gate. When driving through the mesh fence gate, there is no need for people to get off the vehicle. Instead, the tires on one side of the vehicle are used to roll over the wheel rolling bar, and the fence gate is opened through the transmission mechanism. After the vehicle passes, the fence gate is closed. The fence gate opens and closes automatically, which saves energy and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below in conjunction with the accompanying drawings. It should be understood that the contents described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0018] Example 1:

[0019] See also Figure 1 An automatic grassland fence gate includes a center post 1 and two side posts 2. A guide groove 5 is provided between the center post 1 and the side posts 2, and a guide groove 5 is provided on each side. The center post 1 and the side posts 2 are buried at a certain depth, such as 50-70 cm, to improve structural stability.

[0020] The right end of the left guide groove 5 is movably connected to the center column 1 through a hinge. The proximal end of the guide groove has a rotating shaft, which cooperates with the rotating shaft seat installed on the upper end of the center column 1.

[0021] The distal end of the guide groove 5 is connected to the upper frame of the side column 2 through the elastic damping member 3 .

[0022] The elastic damping member 3 includes an elastic body and a damping shock absorber, which cooperate to achieve damping effect and elastic force reset when the guide groove descends and ascends.

[0023] The guide groove 5 is a slender beam with a U-shaped cross section, which is used to accommodate the door body of the net door 4 to slide left and right inside.

[0024] The inner side of the door is welded with multiple evenly distributed and vertically arranged spacers (not shown in the figure), with screens (not shown in the figure) placed between the spacers. This effectively increases the door's strength. The screens also provide a clearer view on both sides of the door, facilitate ventilation, and improve wind resistance.

[0025] The bottom of the door body is provided with a plurality of movable wheels, which are inserted into the guide grooves 5 and support the door body and slide left and right.

[0026] The moving wheel can be an inflatable wheel and the surface is provided with anti-skid grooves, so that it can roll in the guide groove and reduce mechanical vibration.

[0027] The single-sided door body can be formed as a single mesh door or comprised of multiple mesh door units. For example, if the single-sided door body is 3 meters long, it can be configured as three mesh door units, each 1 meter long. The three mesh door units are arranged side by side within the guide groove 5, and are installed in three parallel slots within the guide groove. Each mesh door unit moves independently and has a different left and right sliding stroke. When all three mesh door units slide to the far end of the guide groove, the three mesh door units are in a parallel position, and the mesh door is open. When all three mesh door units slide toward the center of the guide groove, the three mesh door units are in a sequential position, and the mesh door is closed.

[0028] The middle part of the guide groove 5 is connected to the wheel rolling strip 6.

[0029] There is a load-bearing member 7 in the middle of the guide groove 5. The load-bearing member 7 is arranged on the left and right sides of the middle of the guide groove. The base of the load-bearing member 7 is fixedly installed on the guide groove. The side of the load-bearing member 7 is an L-shaped structure. The end of the lower short side of the load-bearing member 7 serves as the base and is fixedly connected to the side of the guide groove. The installation position of the base is the center 1 / 2 of the length of the guide groove.

[0030] The end of the upper long side of the load-bearing member 7 has an axial hole, which is coaxial with the mounting hole at the bottom of the wheel crushing strip 6. The load-bearing member 7 and the wheel crushing strip 6 are movably connected by an axial pin. When the wheel crushing strip 6 moves downward, it can drive the load-bearing member 7 to move at the same time. The axis of the axial hole is basically parallel to the rotation axis of the guide groove 5. The axial pin and the axial hole have a certain matching clearance. When the wheel crushes, the wheel crushing strip 6 can rotate slightly around the axis and swing horizontally relative to the load-bearing member 7.

[0031] There are two inner and outer wheel crushing strips 6 corresponding to the wheels on one side, which are distributed on the inner and outer sides of the guide groove, and can provide inner and outer support for the wheels when the vehicle passes through the fence gate.

[0032] The wheel crushing bar 6 is a rectangular structure, with its upper movable end connected to the load-bearing member 7 via a mounting hole at the lower portion. Its lower fixed end has a rotating shaft, which fits into a shaft slot 11 on the base 10. The shaft rotates within the slot and can also move horizontally within a certain range, ensuring that the wheel crushing bar has room to move forward and backward when pressed down by the vehicle.

[0033] Because wheel-rolling strips 6 are connected to the guide channels, when a vehicle's wheels advance onto the strips, the vehicle's gravity causes the strips to move downward, causing the load-bearing members to rotate the guide channels downward about the axis of the center column 1. The distal end of the guide channels descends from a high position to a low position, allowing the mesh door contained therein to slide freely outward under the action of gravity, thus opening. When the three mesh door units are folded outward and aligned, they form a one-meter width. When folded outward and opened, they create a two-meter-wide space for vehicles to pass through.

[0034] The left and right guide grooves are connected to wheel crushing strips. When a vehicle enters, the left and right wheels need to press on the wheel crushing strips on both sides at the same time to make the left and right guide grooves drop to open the door.

[0035] For other vehicle passage areas where wheel crushing strips are not set, corresponding auxiliary inclined plates 13 need to be set on both sides of the door inside and outside. The auxiliary inclined plates 13 are arranged with an inclined surface, with the lower part touching the ground and the higher part higher than the guide groove height, providing auxiliary support for the vehicle wheels when passing through other areas outside the wheel crushing strips, thereby providing safety and vehicle applicability.

[0036] When a vehicle enters the gate from the outside, it first presses on the two wheel rolling strips on the outside of the guide groove, causing the groove to lower and, in turn, the two wheel rolling strips on the inside. As the vehicle advances, it passes over the guide groove and presses on the two wheel rolling strips on the inside. This pressure holds the guide groove in place until the vehicle finally clears the two wheel rolling strips. When a vehicle exits the gate from the inside, a similar process is followed.

[0037] Example 2:

[0038] Based on Example 1, the implementation plan is improved.

[0039] The wheel crushing strip of the embodiment 1 is connected to the load-bearing member 7 on the guide groove. The wheel crushing strip and the load-bearing member 7 move synchronously and have the same displacement size. In order to achieve the door opening action with a smaller drop of the vehicle under the same pressure of the vehicle, and to speed up the opening speed. Figure 3 As shown, a distance increasing mechanism is added.

[0040] The wheel rolling bar is connected to the guide channel via a distance-increasing mechanism. This distance-increasing mechanism is a crossbar 9, whose fixed end is connected via a pin to an auxiliary column 8, located between the center column 1 and the side columns 2. The other end of the crossbar 9 is connected to the guide channel via a pin. Similarly, two left and right auxiliary columns 8 and two crossbars 9 are provided.

[0041] Wheel crushing strips 6 are connected to crossbars 9. Similar to the first embodiment, the crossbar of the range extender mechanism has a load-bearing member 7 in the middle. This member is attached to the side of the crossbar, and its base is fixedly mounted on the crossbar. The load-bearing member is L-shaped, with the end of its lower short side serving as the base, fixedly attached to the side of the crossbar. The crossbar is connected to the wheel crushing strips via the load-bearing member.

[0042] The distal end of the cross bar (movable end) is located 1 / 3 of the guide slot length from the distal end, and the proximal end of the cross bar (fixed rotating end) is located 2 / 3 of the guide slot length from the distal end. The length of the cross bar is 1 / 3 of the guide slot length.

[0043] The installation position of the load-bearing base is 1 / 2 of the center of the crossbar length or 1 / 3 from the far end of the crossbar.

[0044] When the vehicle's wheels advance onto the wheel-rolling bar, the vehicle's gravity acts as the force, causing the bar to move downward, driving the crossbar to rotate downward, causing its movable end to drop from a high position to a low position. This, in turn, causes the guide slot to rotate downward, causing its movable end to drop from a high position to a low position. The mesh door accommodated therein slides freely outward under the action of gravity, executing the door opening action. By utilizing the amplifying effect of the crossbar of the distance-increasing mechanism, the ratio of the wheel-rolling bar's travel to that of the crossbar's distal end is 1:n, where n>1. This allows the same wheel-rolling bar's travel to achieve a greater travel of the guide slot's movable end, achieving a greater downward slope and facilitating the rapid opening and closing of the mesh door under the action of gravity.

[0045] The crossbars 9 of the distance increasing mechanism need to be respectively arranged on the inner and outer sides of the guide groove and connected to the wheel rolling strips on both sides.

[0046] Example 3:

[0047] Based on Example 1, the implementation plan is improved.

[0048] In the first embodiment, wheel crushing strips on both sides are connected to the guide groove, and the left and right wheels press the wheel crushing strips at the same time, so that the guide grooves on both sides are lowered to open the door. In order to further adapt to the width and distance of the two wheels of different vehicles, a synchronization mechanism is set.

[0049] like Figure 6As shown, two rotation axis holes are horizontally provided at the ends of the center column 1, respectively mateable with the rotation axes of the left and right guide slots. That is, the rotation axes of the two guide slots are arranged horizontally and parallel. A sector-shaped toothed disc 12 is mounted near the guide slots' rotation axes. The sector-shaped toothed disc 12 of the left guide slot meshes with the sector-shaped toothed disc 12 of the right guide slot, achieving synchronous movement of the left and right guide slots, i.e., simultaneous raising or lowering.

[0050] A synchronous mechanism is employed, with only one wheel-rolling strip connected to the corresponding guide channel. When a wheel on one side of the vehicle contacts and depresses the wheel-rolling strip, the left and right guide channels are simultaneously lowered to open the door. Suitable for vehicles of varying widths, only one wheel needs to be rolled.

[0051] According to the position of the driver, the left wheel crushing strip in the forward direction may be preferably connected and installed with the left guide groove to facilitate visual observation by the driver when operating the vehicle.

[0052] How this application works:

[0053] When driving through an automatic energy-saving fence gate, the tire on one side of the vehicle rolls over the wheel rolling strip, which, through the transmission mechanism, causes the outer side of the automatic door track to fall to the ground (the outer side falls to the ground synchronously due to the combined action of the gear discs at the connection of the two tracks). At this time, the track is higher inside and lower outside, with an angle of approximately 2.3° to the horizontal plane. The door body slides outward on the wheels under the action of its own weight, and the fence gate opens when it is in place. After the vehicle passes, the vehicle tire leaves the wheel rolling strip, and under the action of elastic force, the outer side of the track rises (the outer side rises synchronously due to the combined action of the gear discs at the connection of the two tracks). At this time, the track is higher outside and lower inside, with an angle of approximately 2.3° to the horizontal plane. The door body slides inward on the wheels under the action of its own weight, achieving closure.

[0054] In order to shorten the track length, the door body can be designed to be multi-section telescopic.

[0055] In order to ensure the structural stability of the connection between the two doors when closed, two upper and lower U-shaped clips are designed on the inner frame of one door. When the telescopic doors on the left and right sides are in the closed state, the inner frame of the other door is inserted into the U-shaped clip of the opposite door, which increases the stability of the automatic door when closed.

[0056] Telescopic doors should be made of lightweight materials. The guide groove of the telescopic door is equipped with elastic damping elements. When no vehicle is running over the wheel rolling strips, the elastic force overcomes the weight of the two wheel rolling strips, the guide groove, and the telescopic door, causing the outer side of the guide groove to rise and the telescopic door to close.

[0057] An elastic damping member may also be added and connected to the wheel crushing strip, that is, the wheel crushing strip implements elastic support and reset functions.

[0058] Finally, it should be noted that the foregoing description is merely an explanation of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail, those skilled in the art will be able to modify the aforementioned technical solutions or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
