Description

Technical Field

[0001] The invention relates to a gate structure of a water conservancy facility, and in particular to a supporting and unlocking device for a built-in gate plate and a use method thereof. Background Art

[0002] Hydraulic dam is a relatively simple movable dam. It is widely used in agricultural irrigation, fisheries, ship locks, seawater tidal barriers, urban river landscape projects and small hydropower stations. The hydraulic lifting dam has a scientific mechanical structure, does not block water, is not afraid of silt accumulation; is not affected by floating objects; with minimal water loss, it can easily wash away floating objects upstream and make the river clear; the dam is released quickly without affecting flood control safety; and has strong resistance to flood impact. The structure of a hydraulic dam usually consists of a gate plate, a gate plate lifting cylinder and a hydraulic pump station. It uses a gate plate lifting cylinder to directly support the back of the movable water-blocking gate plate with a hinge at the bottom to achieve the purpose of raising the dam to block water and lowering the dam to discharge flood water. In order to make the gate plate lifting cylinder no longer bear the load after the gate plate is lifted, a support rod is added to the back of the gate plate, and together with the gate plate, it forms a "human" shape support, such as patent CN201510923930.9, a foldable and limited hydraulic dam support mechanism, which has: an upper support rod and a lower support rod; the upper support rod and the lower support rod are connected by a hinge, when the hydraulic dam needs to be supported, the upper support rod and the lower support rod are in a straight line, when the support is released, the upper support rod and the lower support rod are bent, and whether the upper support rod and the lower support rod are bent is controlled by a hydraulic cylinder installed on the dam foundation. This kind of hydraulic cylinder is often soaked in water, which affects the service life of the hydraulic cylinder. Although there is another patent CN201520763217.8 hydraulic dam built-in drive support mechanism, it includes a telescopic cylinder arranged along the height direction of the dam body and installed on the dam body; a connecting rod arm, the first end of the connecting rod arm is hinged with the piston rod of the telescopic cylinder; a support rod for supporting the dam body, the upper end of the support rod is fixedly connected to the second end of the connecting rod arm, and the telescopic cylinder is installed in the gap between the longitudinal and transverse beams of the inner arc cavity of the dam body. It is not eroded by water flow and polluted by sediment, which increases the service life and reduces the failure rate. Although the telescopic cylinder of this structure is installed in the gap between the longitudinal and transverse beams of the inner arc cavity of the dam body, it is not eroded by water flow and polluted by sediment, which increases the service life. However, when these structures release the support (unlock), they all need hydraulic cylinders to adjust the position of the support rod. The structure is too complicated and prone to failure. In addition, the manufacturing and use costs are high, and the installation and construction are relatively difficult. There are also some supporting mechanisms such as patent CN201711088793.7, a supporting system based on a hydraulic dam, which includes a connecting seat, a support rod connected to the connecting seat, and a base connected to the end of the support rod. The connecting seat is fixed on the dam surface of the hydraulic dam, and the support rod is connected to the connecting seat through a pin shaft. The base is provided with a groove, and the groove is provided with a bottom surface that is inclined downward from the groove edge close to the dam surface to the groove edge away from the dam surface. A number of steps are provided on the bottom surface, and the groove is provided with two cross plates. A channel is provided between the two cross plates. The extension direction of the channel is consistent with the rising or falling direction of the hydraulic dam surface. The support rod enters the groove through the channel, and a cross bar is provided at the end of the support rod. The cross bar contacts the steps, and a barb is provided on the outer circular surface of the support rod, and an iron wire is provided through the barb, and the two ends of the iron wire are respectively connected to a stretching machine provided on the shore.This structure seems to be relatively simple, but in actual use, when discharging flood water, weeds and rocks in the river channel will accumulate on the inclined bottom surface, filling up the steps on the bottom surface and making the support pole unable to support. Therefore, this structure also has limitations in actual use. Summary of the invention

[0003] The object of the present invention is to provide a supporting and unlocking device for a built-in gate plate and a method for using the device, which has a simple structure, is easy to use and maintain, is not disturbed by debris in the river channel, and works reliably.

[0004] In order to solve the above problems, the hydraulic dam support rod unlocking device of the present invention is realized by the following technical scheme: it is a support rod for supporting the gate plate, characterized in that the support rod includes a cylinder body, a hinge shaft hole is provided at the bottom of the cylinder body, a support rod that is telescopic in the cylinder body is inserted in the cylinder body, a support pin is provided on the end side of the support rod, and a support and unlocking device for controlling whether the support rod is inserted into the cylinder body is provided at the barrel mouth of the cylinder body, the support and unlocking device includes a guide cylinder and a guide groove formed between an upper guide plate and a lower guide plate fixed on the inner wall of the guide cylinder, the support pin moves in the guide groove, wherein the lower guide surface of the lower guide plate is arranged with two √ shapes at intervals, and the axial through groove through which the support pin can pass is between the two intervals, and the upper guide surface of the upper guide plate is formed by inverted reverse √ shapes spliced ​​side by side, and the bottom of the √ shape in the upper and lower guide surfaces is a pit.

[0005] The √-shaped pits in the upper and lower guide surfaces differ by 45 degrees.

[0006] The upper opening of the guide cylinder is provided with a cover plate.

[0007] The lower end surfaces of the lower guide plates on both sides of the through slot are provided with guiding inclined surfaces for facilitating the entry of the supporting pins.

[0008] An upper hinge is sleeved on the head of the support rod, and the support rod can rotate relative to the upper hinge.

[0009] There are two symmetrical support pins on the support rod.

[0010] A rolling sleeve is installed on the supporting pin.

[0011] A bearing is installed between the head of the support rod and the upper hinge.

[0012] The upper hinge is connected to the back of the gate plate, and the hinge shaft hole at the bottom of the cylinder body is fixed to the support hinge on the dam foundation, or the hinge shaft hole at the bottom of the cylinder body is connected to the back of the gate plate, and the upper hinge is fixed to the support hinge on the dam foundation.

[0013] The method for using the supporting and unlocking device of the built-in gate plate is characterized by:

[0014] (1) When it is necessary to raise the dam to block water, the gate plate is gradually lifted by the piston rod of the lifting cylinder. The support rod is pulled out of the cylinder body as the gate plate rises. The support pin on the support rod enters the guide groove through the through groove. When the support pin moves to the upper pit of the upper guide surface, the gate plate rises to the highest position. The lifting cylinder retracts slightly. The support pin reaches the lower pit of the lower guide surface under the guidance of the inclined surface of the lower guide surface. At this time, the support rod rotates 45 degrees. The support pin on the support rod falls into the lower pit of the lower guide surface under the thrust of the gate plate and water pressure, stably supporting and positioning the gate plate, completing the dam raising and water blocking operation;

The gate plate is slightly lifted by the lifting cylinder, and the support pin on the support rod rises and disengages from the lower pit in the lower guide surface. Under the guidance of the inclined surface of the upper guide surface, it reaches the upper pit of the upper guide surface. The lifting cylinder is lowered again, and the support pin enters the through groove and the cylinder body under the guidance of the inclined surface of the outer lower guide surface. At this time, the support rod rotates 45 degrees again, and the support rod returns to the cylinder body as the gate plate descends. The support rod loses support and is unlocked. The gate plate is completely laid down as the piston rod of the lifting cylinder retracts, completing the dam lowering and water release operation.

[0016] According to the above scheme, a built-in gate plate support and unlocking device and its use method are manufactured. It uses the lifting and lowering of the gate plate or the telescopic action of the lifting cylinder to move the supporting rods linked with them synchronously in a three-dimensional guide groove of a support and unlocking device, so as to realize the support of the gate plate by the supporting rods when it is turned up to block water and the unlocking of the dam when it is released, and it can be realized repeatedly. The device cleverly completes the support of the hydraulic dam and the unlocking of the supporting rods, eliminates the problem that the traditional supporting rods must be unlocked by an external power device, simplifies the structure, reduces the technical difficulty of manufacturing and construction, and the unlocking device is non-open, and the guide cylinder not only plays the role of fixing the upper and lower guide plates, but also wraps the entire device, so that it will not be entangled by debris in the waterway and affect the work, and it has a beautiful appearance. It has the advantages of simple structure, low manufacturing cost, convenient use and maintenance, and reliable support. BRIEF DESCRIPTION OF THE DRAWINGS
