[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0025] See also Figures 1 to 3 As shown, a simple gate opening and closing device includes a frame 1, a gate 2, a first screw rod 4, a first motor 5 and a limit assembly 6. The frame 1 is a rectangular structure with a hollow interior. The gate 2 is longitudinally slidably arranged inside the frame 1. An accommodating space 21 is provided inside the gate 2. The lower part of the first screw rod 4 is vertically penetrated in the accommodating space 21, and the bottom end of the first screw rod 4 is screwed with the top of the gate 2. In this embodiment, a screw nut 3 is fixed on the top of the gate 2, and the first screw rod 4 is screwed with the screw nut 3. The top of the first screw rod 4 passes through the top of the frame 1 and extends to the outside of the frame 1. The first motor 5 is fixed on the top of the frame 1 to drive the first screw rod 4 to rotate. Preferably, the top of the first screw rod 4 is turned into a hexagonal shape, so that when a sudden power outage occurs, the first screw rod 4 can be manually rotated with the help of a tool to control the gate 2. The limit assembly 6 is arranged at the top of the frame 1, located on one side of the first screw rod 4, and is used to limit the lifting height of the gate 2.
[0026] During implementation, the first motor 5 drives the first screw rod 4 to rotate forward or reverse, and the gate 2 rises or falls along the axial direction of the first screw rod 4 through the screw nut 3 screwed to the first screw rod 4. When the gate 2 is lifted to a preset height, the limit assembly 6 can achieve emergency braking to prevent the first motor 5 from still driving the first screw rod 4 to rotate when the gate 2 is lifted to the top limit position or the gate 2 is lowered to the bottom limit position, causing damage to the gate 2. It should be noted that when the gate 2 is rising, the bottom end of the first screw rod 4 extends into the accommodating space 21.
[0027] The limit assembly 6 includes a box body 61, a second screw rod 62, a positioning wheel 63, two limit switches 64 and a first power unit 7. The box body 61 is fixed at the top of the frame body 1. The lower part of the second screw rod 62 is vertically penetrated inside the box body 61 and is rotatably connected to the box body 61. In this embodiment, the second screw rod 62 is proportional to the first screw rod 4, that is, the number of threads of the second screw rod 62 is equal to the number of threads of the first screw rod 4, and the pitch of the second screw rod 62 is smaller than the pitch of the first screw rod 4, thereby making the length of the second screw rod 62 much smaller than the length of the first screw rod 4. By arranging the limit assembly at the top of the gate, the problem of water flow directly impacting the limit assembly and causing damage to the limit assembly is avoided.
[0028] The positioning wheel 63 is located inside the box body 61 and is screwed to the second screw rod 62. One side of the positioning wheel 63 is slidably connected to the inner wall of the box body 61, so that the positioning wheel 63 is driven to rise or fall along the axial direction of the second screw rod 62 during the forward or reverse rotation of the second screw rod 62. Two limit switches 64 are respectively fixed on the inner wall of the box body 61 and are respectively located at the preset positions of the upper and lower parts of the box body 61. When the positioning wheel 63 moves to any position of the limit switch 64, the outer wall of the positioning wheel 63 abuts against the sensing end of the corresponding limit switch 64, causing the limit switch 64 to transmit a signal to the first motor 5 for emergency braking to avoid damage to the gate. The first power unit 7 is fixed on the first screw rod 4, and is used to drive the second screw rod 62 to rotate synchronously with the first screw rod 4.
[0029] In this embodiment, the first power unit 7 includes a first synchronous wheel 71 fixedly sleeved on the outer surface of the first screw rod 4, a second synchronous wheel 72 fixedly sleeved on the outer surface of the second screw rod 62, and a first synchronous belt 73 wound around the outside of the first synchronous wheel 71 and the second synchronous wheel 72. During implementation, the first motor 5 drives the first screw rod 4 to rotate, and at the same time drives the first synchronous wheel 71 to rotate. The second synchronous wheel 72 can rotate simultaneously with the first synchronous wheel 71 through the transmission of the first synchronous belt 73, and then drive the second screw rod 62 to rotate synchronously. At this time, the first motor 5 drives the gate 2 to rise and fall through the first screw rod 4, and at the same time drives the positioning wheel 63 to rise and fall through the second screw rod 62. When the gate 2 is lifted and lowered to a preset height, the positioning wheel 63 moves to the sensing end of the limit switch 64, and then emergency braking can be performed to prevent the gate 2 from being damaged.
[0030] In this embodiment, an encoder 8 is also fixedly provided at the top of the frame 1, wherein the encoder is a prior art, and is used to detect the linear displacement of the first screw rod 4, and sends the data of the linear displacement of the first screw rod to the controller, which will not be described in detail here. A fourth synchronous wheel 81 is fixedly provided at the input end of the encoder 8, and a third synchronous wheel 82 is fixedly provided on the outer surface of the first screw rod 4 corresponding to the fourth synchronous wheel 81, and a second synchronous belt 83 is wound around the outer sides of the third synchronous wheel 82 and the fourth synchronous wheel 81. By setting the third synchronous wheel 82, the fourth synchronous wheel 81 and the second synchronous belt 83, the encoder 8 can monitor the rotation data of the first screw rod 4 in real time, so as to better control the rotation position of the first screw rod 4.
[0031] The outer surface of the screw nut 3 is fixedly sleeved with a brush assembly 9 for cleaning the first screw 4. In this embodiment, the brush assembly 9 includes a first fixing ring 91 fixedly sleeved on the outer surface of the screw nut 3 and a second fixing ring 92 arranged above the first fixing ring 91. The second fixing ring 92 is fixedly connected to the first fixing ring 91 through a plurality of connecting rods 93. In this embodiment, the plurality of connecting rods 93 are arranged at intervals along the circumference of the first fixing ring 91. The second fixing ring 92 is sleeved on the outer side of the first screw 4, and a plurality of bristles 94 for cleaning the first screw 4 are fixedly arranged on the inner side wall of the second fixing ring 92.
[0032] During implementation, when the first screw rod 4 rotates forward or reversely and the gate 2 rises or falls along the axial direction of the first screw rod 4, the bristles 94 of the brush assembly 9 can clean the outer surface of the first screw rod 4 to prevent foreign matter from being stuck between the first screw rod 4 and the screw nut 3, causing jamming or reducing the service life of the equipment.
[0033] When the utility model is implemented, the first motor 5 drives the first screw rod 4 to rotate forward or reverse, so that the screw nut 3 screwed to the first screw rod 4 drives the gate 2 to rise or fall along the axial direction of the first screw rod 4. At the same time, the first synchronous wheel 71 drives the second synchronous wheel 72 to rotate through the first synchronous belt 73, so that the second screw rod 62 rotates synchronously with the first screw rod 4, and then the positioning wheel 63 moves up and down along the axial direction of the second screw rod 62. Because the second screw rod 62 and the first screw rod 4 are proportional, the displacement ratio of the positioning wheel 63 relative to the second screw rod 62 is the same as the displacement ratio of the gate 2 relative to the first screw rod 4. Therefore, when the positioning wheel 63 moves to one side of the limit switch 64, the outer wall of the positioning wheel 63 abuts against the sensing end of the limit switch 64, and the limit switch 64 feeds back a signal to the first motor 5, so that the first motor 5 is emergency braked to prevent the gate 2 from rising to the top limit position or the gate 2 from falling to the bottom limit position. The first motor 5 still drives the first screw rod 4 to rotate, causing damage to the gate 2. At the same time, by adding an encoder 8, the rotation position of the first screw rod 4 can be better controlled.
[0034] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
