Description

Technical Field

[0001] This application relates to the field of gate hoisting technology, specifically to a high-precision gate hoisting machine for water conservancy projects. Background Technology

[0002] Gate hoists, as large-scale hydraulic machinery products, are crucial to the normal operation of hydraulic structures. Gate hoists can be classified according to their operating power into manual, electric, and hydraulic gate hoists; and according to their power transmission method into mechanical and hydraulic transmission gate hoists. Mechanical transmission can be further divided into four types: belt drive, chain drive, gear drive, and combined drive; while hydraulic transmission can be divided into oil pressure transmission and water pressure transmission.

[0003] Chinese patent document CN221810566U discloses a water conservancy gate for water conservancy engineering construction, specifically disclosing a dam body. The dam body has a movable opening at its top, and a sliding groove on one side of the inner wall of the gate opening. A fixed frame is located at the top of the dam body; a top plate is located at the top of the fixed frame, and a second movable opening is located at the top of the top plate; a filter blocking mechanism is located on one side of the dam body; and an opening and closing mechanism is located on one side of the inner wall of the gate opening. This utility model achieves the effect of filtering and collecting waste at the dam body's gate opening by using a filter plate that does not obstruct the gate opening when the gate is closed. Before the gate is opened by the opening and closing mechanism, a hydraulic telescopic rod is activated. The movement of the hydraulic telescopic rod drives a movable sleeve, which in turn moves a fixed seat. The fixed seat then causes the filter plate to block the gate opening. At this time, the gate is activated, causing the collection trough to rise, thus achieving the effect of filtering and collecting waste at the gate opening of the dam body.

[0004] However, in the aforementioned patent, the hydraulic telescopic rod is completely exposed, resulting in poor protection and easy damage. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this application provides a high-precision gate opening and closing machine for water conservancy projects.

[0006] This application adopts the following technical solution: a high-precision gate opening and closing machine for water conservancy projects, including a hydraulic cylinder, wherein the hydraulic cylinder includes a cylinder body and a piston rod, the piston rod is inserted into the cylinder body and slides adaptedly within the cylinder body, a plurality of parallel protective plates are sleeved on the outer wall of the cylinder body, three of the protective plates are spaced apart along the length direction of the cylinder body, a reinforcing rod is passed through the three protective plates, the protective plates are provided with threaded holes, and the reinforcing rod is connected to the protective plates by threads;

[0007] Both ends of the reinforcing rod are fitted with a nut, which presses against the outside of the guard plate.

[0008] Optionally, the cylinder body has at least three protective plates on its outer side, and at least four reinforcing rods are inserted through the protective plates, with a plurality of the reinforcing rods located on the outer side of the cylinder body.

[0009] Optionally, the protective plate has a first cavity, the reinforcing rod has a second cavity, the first cavity and the second cavity are interconnected, the outer wall of the protective plate has a plurality of nozzles, the nozzles are connected to the first cavity, and the outer wall of the protective plate located in the middle of the cylinder has a water inlet, the water inlet is used to deliver water into the first cavity, and the water is sprayed out through the nozzles.

[0010] Optionally, the inner side of the guard plate is provided with a first through hole, which connects the threaded hole and the first cavity, and the inner side of the reinforcing rod is provided with a second through hole, which are interconnected and coaxially arranged.

[0011] Optionally, the nozzle is inclined toward the outer wall of the cylinder; one end of the nozzle is located on the outside of the protective plate, and the other end of the nozzle is located on the inside of the first cavity. The other end of the nozzle is provided with a solenoid valve, which is used to control the opening and closing of the nozzle.

[0012] Compared to existing technologies, this application improves the protection of the cylinder body by using several protective plates and reinforcing rods, preventing damage to the cylinder body. Simultaneously, by creating a first cavity within the protective plates and a second cavity within the reinforcing rods, with the first and second cavities interconnected, and by installing a nozzle on the protective plates that communicates with the first cavity, water entering the first and second cavities can be sprayed outwards through the nozzles, effectively cleaning the outer wall of the cylinder body and dissipating heat to cool it.

[0017] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] like Figure 1-3 As shown, a high-precision gate opening and closing machine for water conservancy projects includes a hydraulic cylinder 1. The hydraulic cylinder 1 includes a cylinder body 11 and a piston rod 12. The piston rod 12 is inserted into the cylinder body 11 and slides within the cylinder body 11. Several parallel guard plates 2 are fitted on the outer wall of the cylinder body 11. Three guard plates 2 are spaced apart along the length of the cylinder body 11. A reinforcing rod 3 passes through the three guard plates 2. The guard plates 2 are provided with threaded holes 21. The reinforcing rod 3 is connected to the guard plates 2 by threads. A nut 4 is screwed onto both ends of the reinforcing rod 3. The nut 4 presses against the outside of the guard plate 2.

[0019] After the two nuts 4 are tightened, the position of the guard plate 2 is adjusted and fixed. At this time, the guard plates 2 and the reinforcing rods 3 cooperate to reliably protect the cylinder body 11, effectively prevent large debris from hitting the outer wall of the cylinder body 11 and causing damage to the cylinder body 11, extend the service life of the cylinder body 11, and ensure that the hoist is in a reliable working state.

[0020] At least three protective plates 2 are provided on the outer side of the cylinder body 11, and at least four reinforcing rods 3 are provided on the protective plates 2. Several reinforcing rods 3 are located on the outer side of the cylinder body 11. In this way, while ensuring the reliable protection effect of the cylinder body 11, the number of protective plates 2 and reinforcing rods 3 is effectively reduced, thereby playing a role in controlling costs.

[0021] The protective plate 2 has a first cavity 22, and the reinforcing rod 3 has a second cavity 31. The first cavity 22 and the second cavity 31 are interconnected. Several nozzles 5 are provided on the outer wall of the protective plate 2, and the nozzles 5 are connected to the first cavity 22. A water inlet 23 is provided on the outer wall of the protective plate 2 located in the middle of the cylinder body 11. The water inlet 23 is used to supply water into the first cavity 22, and the water is sprayed outwards through the nozzles 5. When an external water source supplies water into the first cavity 22 through the water inlet 23, the water will fill the first cavity 22 and the second cavity 31, and then spray outwards from the nozzles 5. In this way, the water sprayed from the nozzles 5 can clean the outer wall of the cylinder body 11, preventing corrosion caused by excessive debris between the outer wall of the cylinder body 11 and the protective plate 2. Furthermore, the flushing action of the water can reduce the surface temperature of the cylinder body 11, thereby achieving heat dissipation and cooling of the cylinder body 11, ensuring that the cylinder body 11 is in a reliable working state.

[0022] The inner side of the guard plate 2 is provided with a first through hole 24, which connects the threaded hole 21 and the first cavity 22. The inner side of the reinforcing rod 3 is provided with a second through hole 32. The first through hole 24 and the second through hole 32 are interconnected and coaxially arranged. The arrangement of the first through hole 24 and the second through hole 32 ensures that the first cavity 22 and the second cavity 31 can be in a state of mutual communication, thereby ensuring that water can be transported through the second cavity 31 to the second cavities 31 of multiple guard plates 2, so that all nozzles 5 can spray water. Furthermore, in order to improve the flow efficiency of water, multiple first through holes 24 can be provided on the guard plate 2 and multiple second through holes 32 can be provided on the reinforcing rod 3.

[0023] The nozzle 5 is inclined towards the outer wall of the cylinder 11; one end of the nozzle 5 is located on the outside of the protective plate 2, and the other end of the nozzle 5 is located on the inside of the first cavity 22. The other end of the nozzle 5 is equipped with a solenoid valve 50, which is used to control the opening and closing of the nozzle 5. When water is first delivered into the first cavity 22 and the second cavity 31, the solenoid valve 50 can be closed, so that the nozzle 5 is in a state where it cannot spray water. When the first cavity 22 and the second cavity 31 are filled with water and the water pressure is high, the solenoid valve 50 opens. At this time, the nozzle 5 can spray water with higher pressure outward, thereby improving the rinsing effect on the outer wall of the cylinder 11.

[0024] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
