Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a rolling friction tension type slot gate. Background Art

[0002] The trough gate is a device commonly used to control water flow in water conservancy projects. Its driving direction is different from the existing lifting plate gate structure. It controls the gate plate and the water flow by rotation. Therefore, its driving direction is also relatively special. First of all, two side plates are symmetrically arranged on both sides of the gate plate of the trough gate, and a chain or rack is also arranged on the side of the two side plates away from the gate plate rotation axis to cooperate with the drive assembly to drive the gate plate to flip. In actual use, in order to ensure that the moving trajectory of the side plate is the preset path, a structure for limiting is usually set on its side, but the existing trough gate side plate limiting mechanism generally adopts sliding friction and cannot be adjusted. Utility Model Content

[0003] In order to solve the problem that the sliding friction type limiting method of the above-mentioned slot gate side plate limiting mechanism has many shortcomings, the utility model provides a rolling friction tension type slot gate.

[0004] The technical solution of this utility model is as follows:

[0005] A rolling friction tensioning slot gate comprises a frame arranged on a reference plane, a driving assembly is arranged above the frame, a gate plate is rotatably connected to the lower part of the frame, and the gate plate can be driven to rotate by the driving assembly and can be sealed with the inner side of the frame in a vertical state, the gate plate comprises a blocking plate and side plates symmetrically arranged on both sides, the driving assembly is provided with a mounting seat at a position close to the side plate, the mounting seat is connected to an adjusting seat, the adjusting seat can move relative to the mounting seat, and the moving direction is parallel to the gate plate rotation axis, and a limiting rotating wheel is arranged at a position close to the side plate of the adjusting seat.

[0006] Different from the existing sliding friction method, a rolling friction method is used for limiting, and the above-mentioned limiting mechanism can be moved, so the tension can be adjusted according to needs.

[0007] As a preferred solution, the rotation axis of the limit wheel is perpendicular to the rotation axis of the gate plate, so as to minimize the friction between the limit wheel and the gate plate.

[0008] In order to limit the gate plate in two directions, the two limit wheels are respectively located on different sides of the adjacent side plates, so as to avoid the two limit wheels being located on the same side of the gate plate.

[0009] As a preferred solution, the two limit rotating wheels are both located on one side of the adjacent side plate close to the center of the two side plates.

[0010] In order to block the gate plate, a limit block is provided on one side of the side plate away from the center of the two side plates, and two limit blocks are provided, which can respectively contact the frame when the blocking plate reaches a vertical and horizontal state. To a certain extent, the pressure of the driving assembly can be reduced.

[0011] On the basis of the above structure, further, the two ends of the side plate away from the center are provided with support blocks, and the support blocks can conflict with the reference plane when the barrier plate reaches the vertical and horizontal states. The limit blocks respectively conflict with the frame and the reference plane and support the gate plate.

[0012] In order to avoid affecting the rotation of the gate plate, the limiting rotating wheel is located on the side of the driving assembly away from the blocking plate.

[0013] The adjustment seat is connected to the mounting seat by a waist-shaped hole, and the length direction of the waist-shaped hole is parallel to the gate rotation axis. The position of the adjustment seat relative to the mounting seat can be adjusted by tightening the waist-shaped hole.

[0014] As a preferred solution, the plane where the side plate is located is perpendicular to the gate plate rotation axis.

[0015] The specific structure of the gate plate is that the side plate is fan-shaped, and the center of the circle is located on the rotation axis of the gate plate.

[0016] The beneficial effect of the utility model is that the utility model is a rolling friction tensioning type slot gate, which is different from the existing sliding friction limiting gate side plate method. The device is the first to use a limiting wheel to resist and tighten the above-mentioned side plate, and then the side plate can be limited by rolling friction, which not only does not affect its normal rotation, but also can be tightened to a certain extent, and in conjunction with the two limiting wheels, the rotation of the above-mentioned gate plate can be made more stable.

[0026] like Figure 1-5 A rolling friction tension type trough gate shown includes a frame 1 arranged on a reference plane, wherein the reference plane 1 is generally the upper surface of the canal, and both sides of the frame 1 also need to be fixed to the sides of the canal. After fixation, the water flow in the canal must pass through the frames 1, so after the gate plate 2 is set, the water flow can be controlled.

[0027] And if Figure 1 As shown, a driving assembly 3 is arranged above the frame 1, and the driving assembly 3 is used to provide power to change the state of the gate 2. In order to facilitate maintenance and manual processing under special circumstances, the driving assembly 3 generally includes two driving modes: electric and manual. Afterwards, the gate 2 is rotatably connected to the bottom of the frame 1, and the gate 2 can be driven to rotate and change its state by the driving assembly 3. It should be noted that in the above structure, the gate 2 can be sealed with the inner side of the frame 1 in a vertical state to ensure that when the gate 2 is in a sealed state, there will be no water leakage, and as shown Figure 5 As shown, the gate plate 2 includes a baffle plate and side plates 21 symmetrically arranged on both sides, wherein the baffle plate is used to cut off the water flow, and generally its rotation plane is parallel to the water flow direction. After its rotation, its highest end will change height, thereby achieving a water control effect, and the side plate 21 needs to cooperate with the drive assembly 3 to rotate.

[0028] Generally, the plane where the side plate 21 is located is perpendicular to the rotation axis of the gate plate 2. In other words, the side plate 21 can rotate around the rotation of the gate plate 2, so it is only necessary to drive the side plate 21 to rotate.

[0029] To this end, the specific structure of the above-mentioned gate plate 2 is that the side plate 21 is fan-shaped, and the central angle of the fan is generally 90° to ensure that the barrier plate can switch between horizontal and vertical states, and in the above structure, the center of the side plate 21 is located on the rotation axis of the gate plate 2.

[0030] The driving assembly 3 drives the side plate 21 in a general manner by chain transmission or gear transmission. Since the present device has not changed it, it will not be described in detail. The key point is that the driving assembly 3 is provided with a mounting seat 4 at a position close to the side plate 21, and then the mounting seat 4 is connected to an adjustment seat 5, and it should be specially noted that the adjustment seat 5 can move relative to the mounting seat 4, and the moving direction is parallel to the rotation axis of the gate plate 2. Relative to the side plate 21, the moving direction of the adjustment seat 5 relative to the mounting seat 4 is perpendicular to the plane where the side plate 21 is located. Therefore, on this basis, a limiting rotary wheel 6 is provided at a position close to the side plate 21 of the adjustment seat 5, and the limiting rotary wheel 6 conflicts with the side plate 21. Therefore, by adjusting the position of the adjusting seat 5, the limiting rotary wheel 6 conflicts with the limiting side plate 21, and the rotation axis of the limiting rotary wheel 6 is not arbitrarily set. In order to obtain the best rolling friction effect, the rotation axis of the limiting rotary wheel 6 is perpendicular to the rotation axis of the gate plate 2. The friction between the limiting rotating wheel 6 and the gate plate 2 can be minimized as much as possible, and the limiting rotating wheel 6 is always tangential to the rotation direction of the side plate 21.

[0031] It should be noted that, in the above structure, the gate plate 2 cannot be limited by a single limiting rotating wheel 6. Therefore, in order to limit the gate plate 2 in two directions, as shown in FIG. Figure 4 As shown, the two limit wheels 6 are respectively located on different sides of the adjacent side plates 21. Avoid the two limit wheels 6 being located on the same side of the gate plate 2. That is, there are only two settings, namely, the two limit wheels 6 are both close to the side of the gate plate center or are both located on the side away from the gate plate center.

[0032] Both designs are possible, but in actual application, in order to avoid interfering with the rotation of the side plates 21 , the two limit wheels 6 are located on one side of the adjacent side plates 21 close to the center of the two side plates 21 .

[0033] The above structure can realize that, different from the existing sliding friction method, a rolling friction method is used to limit the position, and the above limiting mechanism can be moved, so the tension can be adjusted according to the needs.

[0034] In addition to the above structure, in order to block the gate plate 2, a limit block 22 is provided on the side of the side plate 21 away from the center of the two side plates 21, and two limit blocks 22 are provided, which can respectively contact the frame 1 when the blocking plate reaches the vertical and horizontal states. To a certain extent, the pressure of the driving assembly 3 can be reduced. And the limit block 22 needs to be arranged on different sides of the same adjacent side plate 21 with the limit rotating wheel 6 to avoid mutual interference between the two during the movement process.

[0035] Afterwards, based on the above structure, further, the two ends of the side plate 21 away from the center are provided with support blocks 23, and the support blocks 23 can collide with the reference plane when the baffle plate reaches the vertical and horizontal states. Cooperating with the limit block 22, they respectively collide with the frame 1 and the reference plane and support the gate plate 2. That is to say, when the baffle plate of the gate plate 2 is in the horizontal or vertical state, the limit block 22 and the support block 23 can respectively collide with the frame and the reference plane to provide support.

[0036] Finally, if Figure 4 As shown, in order to avoid affecting the rotation of the gate plate 2, the limiting rotating wheel 6 is located on the side of the driving assembly 3 away from the blocking plate, so as to prevent the blocking plate from colliding with the limiting rotating wheel 6 and its related connecting parts.

[0037] As a preferred embodiment, the adjustment seat 5 is connected to the mounting seat 4 by connecting the adjustment seat 5 to the mounting seat 4 through a waist-shaped hole, and the length direction of the waist-shaped hole is parallel to the rotation axis of the gate plate 2. The position of the adjustment seat 5 relative to the mounting seat 4 can be adjusted by tightening the waist-shaped hole.
