Technical Field

[0001] The utility model belongs to the technical field of water conservancy and hydropower equipment, and in particular relates to a water conservancy and hydropower intercepting device. Background Art

[0002] Water conservancy and hydropower is a field that uses the energy of water resources to generate electricity and manage water resources. Water conservancy and hydropower is a renewable energy source because water resources are continuously recycled. At present, water conservancy and hydropower have become one of the most important sources of energy in the world. The interception device is a temporary enclosure structure built in the construction of water conservancy projects to build permanent water conservancy facilities. Its function is to prevent water and soil from entering the construction location of the building so that drainage can be carried out in the interception device, foundation pits can be excavated, and buildings can be built. However, the existing water conservancy and hydropower interception devices will cause the water level to rise after the interception treatment due to the interception of the water flow. Most interception devices are not equipped with water level monitoring and alarm devices, which makes it easy for the water level to overflow the dam or interception device and fail to provide warnings. Utility Model Content

[0003] The utility model aims to provide a water conservancy and hydropower interception device, which solves the problem that the existing water conservancy and hydropower interception water level cannot provide a warning when it overflows the dam or the interception device.

[0005] The utility model is also characterized in that:

[0006] The intercepting mechanism includes a first intercepting plate, which is arranged on one side of the dam, and a second intercepting plate is arranged on the other side of the dam. A movable groove is opened on one side of the surface of the first intercepting plate, and several groups of hydraulic cylinders are installed inside the movable groove. The other ends of the several groups of hydraulic cylinders are fixedly connected to baffles. An engaging groove is opened on one side of the surface of the second intercepting plate.

[0007] The first shutoff plate corresponds to the second shutoff plate.

[0008] The baffle is embedded in the first intercepting plate, and the size of the baffle is consistent with the embedding groove.

[0011] The beneficial effects of the utility model are:

[0012] The water conservancy and hydropower intercepting device provided by the utility model is provided with an alarm mechanism. When the water level rises, the water body drives the float ball to float up.

A movable groove 203 is provided on one side of the surface of the first intercepting plate 201, and a plurality of groups of hydraulic cylinders 204 are installed inside the movable groove 203. A baffle 205 is fixedly connected to the other end of the plurality of groups of hydraulic cylinders 204. A fitting groove 206 is provided on one side of the surface of the second intercepting plate 202; the first intercepting plate 201 corresponds to the second intercepting plate 202; the baffle 205 is fitted inside the first intercepting plate 201, and the size of the baffle 205 matches that of the fitting groove 206, so that the baffle 205 and the fitting groove 206 can be matched to facilitate interception; as shown Figure 3 As shown, the alarm mechanism 5 includes a monitor 501, which is arranged on one side of the surface of the mounting plate 4. A buzzer 502 and an alarm light 503 are electrically connected to one side of the surface of the monitor 501, and a monitoring barrel 504 is arranged on the other side of the monitor 501. Figure 4 As shown, a water inlet 505 is provided on one side of the surface of the monitoring barrel 504, a float 506 is provided inside the monitoring barrel 504, a drain outlet 507 is provided on the side wall at one end of the monitoring barrel 504 away from the water inlet 505, a switch 508 is provided at one end of the monitoring barrel 504 close to the drain outlet 507, and the switch 508 is electrically connected to the monitoring instrument 501; the diameter of the float 506 is larger than the size of the water inlet 505.

[0020] The water conservancy and hydropower intercepting device provided by the utility model has the following working principle: when interception treatment is required, firstly, the first intercepting plate 201 and the second intercepting plate 202 are installed on one side of the surface of the dam 1 and the first intercepting plate 201 and the second intercepting plate 202 are aligned, and then the hydraulic cylinder 204 is opened, at which time the hydraulic cylinder 204 drives the baffle 205 to move, so that the baffle 205 moves out from the inside of the movable groove 203 and moves toward the second intercepting plate 202, when one end of the baffle 205 is embedded in the inside of the embedding groove 206 opened on one side of the surface of the second intercepting plate 202, at this time, the first intercepting plate 201, the second intercepting plate 202 and the baffle 205 form a whole to intercept the water flow. After the interception mechanism 2 intercepts the flowing water, the water level will rise. When the water level is above the bottom of the monitoring barrel 504, the water flows into the interior of the monitoring barrel 504 from the water inlet 505. At this time, due to the effect of buoyancy, the float 506 rises with the water level. When the water level reaches the warning line, the float 506 touches the switch 508, so that the switch 508 controls the monitoring instrument 501 to issue instructions to the buzzer 502 and the alarm light 503. At this time, the buzzer 502 sounds an alarm and the alarm light 503 flashes, so that the operating personnel can promptly discover the water level situation and take early warning measures to avoid the water level from overflowing the dam 1, the first interception plate 201 and the second interception plate 202.
