Abstract
Description
Technical field
[0001] The utility model relates to the field of hydraulic dams, in particular to a hydraulic dam with a sealed box. [Background Technology]
[0002] A hydraulic lifting dam is a movable dam that uses the mechanical principles of dump trucks and combines the hydraulic structure of a pier dam with the dual functions of retaining and releasing water. Currently, there are two common drive modes for hydraulic dams: a bottom shaft drive and a direct push panel drive. Both modes are designed based on the drive mode selected on site.
[0003] The bottom shaft driven hydraulic dam reserves a cylinder groove on the downstream side to ensure the normal operation of the hydraulic cylinder. However, the cylinder groove is lower than the horizontal plane of the downstream foundation, which often causes problems such as liquid accumulation and floating objects blocking the cylinder groove over time, causing the hydraulic cylinder to be locked and affecting the normal operation of the gate. Therefore, this sealed box is invented to ensure that no mud or other debris enters the cylinder groove. [Utility Model Content]
[0004] In order to solve the above problems, the purpose of the utility model is to provide a hydraulic dam with a sealed box body, a dam body and a groove, the groove is opened at the bottom of the dam body, a plurality of sealed boxes are installed in the groove, the sealed boxes are connected to each other, a main oil cylinder is installed in the sealed box, the movable end of the main oil cylinder is connected to the gate arm through the cylinder shaft to control the opening and closing of the gate;
[0005] A drainage assembly, wherein the drainage assembly is installed inside the sealed box;
[0006] The drainage assembly includes a drainage pipe, which is installed inside the sealed box and extends out of both ends. The drainage pipes are interconnected. A water collection well is provided at the bottom of the sealed box on the right side, and a water pump is provided in the water collection well.
[0007] Preferably, a hoist embedded steel plate is welded to one side of the sealing box.
[0008] Preferably,.
[0009] Compared with the existing technology, a sealing cover is provided on the top of the sealing box to prevent the entry of mud or other debris in the oil cylinder groove. Since the sealing box includes four sides and a top cover, and the bottom groove is made of concrete, concrete can easily cause water leakage over time. The sealing boxes are connected by a drainage pipe, and the drainage pipe is a pre-buried PVC drainage pipe, so that all the grooves are connected into a whole. A water collection well is preset at the bottom of the right oil cylinder groove, and an automatic water pump is provided in the water collection well. By monitoring the water level, the water pump automatically drains water to keep all oil cylinder grooves in a water-free working environment at all times, ensuring the long-term normal operation of the oil cylinder, thereby reducing the accumulation of liquid inside the groove and ensuring that there is no liquid accumulation in the sealing box, thereby achieving a sealing effect. The top of the cover is connected with a special protective cloth and a crank arm, which is retractable and will not get stuck, and at the same time, the top of the cover has a sealing effect.

[0014] The hydraulic dam with a sealed box according to the present invention will be further described in detail below through specific embodiments.
[0015] As shown in the figure, a hydraulic dam with a sealed box body includes a dam body 1 and a groove 2. The groove 2 is opened at the bottom of the dam body 1. A plurality of sealed boxes 3 are installed in the groove 2. The sealed boxes 3 are connected to each other. A main oil cylinder 4 is installed in the sealed box 3. The movable end of the main oil cylinder 4 is connected to the cylinder shaft 5. The cylinder shaft 5 is connected to the gate crank arm 6.
[0016] Drainage assembly, the drainage assembly is installed inside the sealing box 3;
[0017] The drainage assembly includes a drainage pipe 8, which is installed inside the sealed box 3 and extends out of both ends. The drainage pipes 8 are interconnected. A water collection well 9 is opened at the bottom of the right sealed box 3. A water pump 10 is installed in the water collection well 9. A pre-buried steel plate 11 for the hoist is welded to one side of the bottom of the sealed box 3.
[0018] A sealing cover is provided on the top of the sealing box 3 to prevent the entry of mud or other debris in the oil cylinder groove. Since the sealing box body includes four sides and a top cover, the bottom of the groove 2 is concrete, and concrete can easily cause water leakage over time. The sealing boxes 3 are connected by a drainage pipe 8, and the drainage pipe 8 is a pre-buried PVC drainage pipe, so that all the grooves 2 are connected as a whole. A water collection well 9 is preset at the bottom of the right oil cylinder groove. An automatic water pump 10 is provided in the water collection well 9. By monitoring the water level, the water pump 10 automatically drains water to keep all oil cylinder grooves in a water-free working environment at all times, ensuring the long-term normal operation of the oil cylinder, thereby reducing the accumulation of liquid inside the groove 2, and ensuring that there is no liquid accumulation in the sealing box 3, thereby achieving a sealing effect. The top of the cover is connected with a special protective cloth and a bend wall, which is flexible and will not get stuck, and at the same time, the top of the cover has a sealing effect.
