Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy engineering dam that is easy to replace. Background Technology

[0002] A sluice gate used on a natural river channel to regulate the upstream water level and control the downstream flow is also called a river control gate. The main functions of a river control gate are: during the dry season, the gate is closed to raise the upstream water level to meet the requirements of navigation, irrigation, power generation, and urban water supply; during the flood season, the gate is opened to release floodwater, so that the upstream water supply level does not exceed the flood control limit level, while controlling the downstream flow to ensure that it does not exceed the safe discharge capacity of the downstream river channel. On rivers with high sediment content, river control gates also have the task of desilting and releasing sediment to maintain the original water and sediment balance of the riverbed as much as possible.

[0003] Utility model patent CN214737853U discloses "A Replaceable Water Conservancy Project Barrier Gate," which includes a barrier gate body. The barrier gate body includes a bank foundation, a first support rod connected to one side surface of the bank foundation, and a threaded rod inserted inside the first support rod. The bottom surface of the threaded rod is connected to a fixing mechanism via a bearing. A gate plate abuts against the inner wall of the bank foundation, and a filtering mechanism is connected to the surface of the gate plate. The fixing mechanism includes a first connecting sleeve, a first support rod, a first strut, and a first cover plate. This water conservancy project barrier gate, which is easy to replace, allows for convenient replacement of the gate plate through the fixing mechanism. Furthermore, the device, through the inclusion of a filtering mechanism, facilitates the removal of river debris through a first filter screen during gate plate replacement.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: the water conservancy project dam that is easy to replace uses a sliding connection between the dam and the sluice plate. During the opening of the dam, silt will block the sliding groove at the lower end of the sluice plate, preventing the dam from being in close contact with the ground and causing water leakage. In the way that the filter screen is connected to the dam plate, when the dam is opened normally to release water, the filter screen will rise with the dam and leave the water surface, making it difficult to intercept floating objects. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water conservancy project dam that is easy to replace, which can prevent silt and other debris from accumulating in the limiting groove, prevent the dam from not closing completely when closing, prevent the filter screen from rising with the gate and leaving the water surface, and ensure that the filter screen can keep intercepting floating objects when the dam is opened to release water, so as to facilitate the staff to carry out unified retrieval later.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A water conservancy project river dam that is easy to replace includes a bank base, on which an operating room is fixedly installed, and the operating room is equipped with a dam opening mechanism and a filtration mechanism.

[0008] The gate opening mechanism includes a first motor, a first helical gear fixedly connected to the output end of the first motor, an internally threaded tube rotatably mounted on the operating chamber, a second helical gear fixedly connected to the internally threaded tube, the second helical gear meshing with the first helical gear, a lead screw internally threaded to the internally threaded tube, a fixing plate fixedly connected to the bottom end of the lead screw, and a gate assembly provided at the bottom of the fixing plate.

[0009] The filtration mechanism includes a second motor, which is fixedly installed in the operating chamber. A roller is fixedly connected to the output end of the second motor. A support column is rotatably installed on the roller. The support column is fixedly connected to the inner wall of the operating chamber. A suspension rope is wound around the roller. A lifting ring is fixedly connected to the bottom end of the suspension rope. A filter screen is fixedly connected to the bottom surface of the lifting ring.

[0010] Preferably, the gate assembly includes a connecting plate, the top surface of which is fixedly connected to the bottom surface of a fixing plate, a river-blocking gate is slidably connected to the connecting plate, and two sliding plates are fixedly connected to both sides of the river-blocking gate, with the sliding plates slidably connected to the fixing plate.

[0011] Preferably, a limiting block is slidably installed on the river-blocking gate, the limiting block has a T-shaped groove, the top surface of the river-blocking gate has a first limiting circular hole, the limiting block has a second limiting circular hole corresponding to the first limiting circular hole, and a pin is engaged in the first limiting circular hole and the second limiting circular hole.

[0012] Preferably, the fixing plate is bolted to the shore foundation, and a limiting groove is formed in the fixing plate, the size of which is adapted to the size of the sliding plate.

[0013] Preferably, the top surface of the operating chamber is provided with a clearance hole, the size of which is larger than the size of the lead screw.

[0014] Preferably, the filter screen is slidably connected to both sides by a limiting slide plate, which is fixedly installed on the shore base.

[0015] Preferably, a ladder is fixedly connected to the rear surface of the operating room, and an opening and closing door is hinged to the rear surface of the operating room.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] First, by setting up a filter screen in the filtration mechanism, floating garbage and debris in the river can be intercepted far away from the dam. The filter screen does not leave the water surface when the dam is raised. When the dam is opened to release water, the filter screen can keep intercepting floating objects, which is convenient for staff to collect them later. At the same time, by starting the second motor, the filter screen can be driven to rise, so as to avoid excessive garbage and debris accumulating in front of the filter screen when the dam needs to be opened to release floodwater, which would affect the water release speed.

[0018] Secondly, the sliding plate and the limiting groove allow the sliding plate to slide up and down within the limiting groove, thereby preventing silt and other debris from accumulating in the limiting groove and ensuring that the dam can be fully closed when it is shut down.

[0026] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-5 A water conservancy project dam that is easy to replace includes a bank base 1, an operating room 2 fixedly installed on the bank base 1, and a dam opening mechanism 3 and a filtering mechanism 6 provided on the operating room 2.

[0028] The gate opening mechanism 3 includes a first motor 301, the output end of which is fixedly connected to a first helical gear 302. An internally threaded tube 304 is rotatably mounted on the operating chamber 2. A second helical gear 303 is fixedly connected to the internally threaded tube 304. The second helical gear 303 meshes with the first helical gear 302. A lead screw 305 is internally threaded onto the internally threaded tube 304. A fixing plate 306 is fixedly connected to the bottom end of the lead screw 305. A gate assembly is provided at the bottom of the fixing plate 306.

[0029] The filtration mechanism 6 includes a second motor 61, which is fixedly installed inside the operating chamber 2. A roller 63 is fixedly connected to the output end of the second motor 61. A support column 62 is rotatably installed on the roller 63. The support column 62 is fixedly connected to the inner wall of the operating chamber 2. A suspension rope 64 is wound around the roller 63. A lifting ring 65 is fixedly connected to the bottom end of the suspension rope 64. A filter screen 66 is fixedly connected to the bottom surface of the lifting ring 65.

[0030] Specifically, the gate assembly includes a connecting plate 307, the top surface of which is fixedly connected to the bottom surface of a fixing plate 306. A river-blocking gate 308 is slidably connected to the connecting plate 307. Two sliding plates 309 are fixedly connected to both sides of the river-blocking gate 308. A fixing plate 310 is slidably connected to the sliding plates 309.

[0031] With the above technical solution, when it is necessary to replace the dam 308, the pin 5 can be pulled out and the limit block 4 can be pulled out from the dam 308 to replace the dam 308.

[0032] Specifically, a limiting block 4 is slidably installed on the river-blocking gate 308, a first limiting circular hole is opened on the top surface of the river-blocking gate 308, and a second limiting circular hole corresponding to the first limiting circular hole is opened on the limiting block 4. A pin 5 is engaged in the first limiting circular hole and the second limiting circular hole.

[0033] The above technical solution can limit the connection plate 307 and facilitate the replacement of the river dam 308.

[0034] Specifically, the fixing plate 310 is bolted to the shore base 1, and a limiting groove is provided in the fixing plate 310. The size of the limiting groove is adapted to the size of the sliding plate 309.

[0035] The above technical solution allows the slide plate 309 to slide up and down within the limiting groove, thereby preventing silt and other debris from accumulating in the limiting groove and ensuring that the dam 308 can be fully closed when it is shut off.

[0036] Specifically, the top surface of the operating chamber 2 is provided with a clearance hole, the size of which is larger than the size of the lead screw 305.

[0037] The above technical solution ensures that the lead screw 305 will not be obstructed when it rises.

[0038] Specifically, the filter screen 66 is slidably connected to both sides by a limiting slide plate, which is fixedly installed on the shore base 1.

[0039] The above technical solution allows the filter screen 66 to be limited by the limiting slide plate when the filter screen 66 is raised or lowered.

[0040] Specifically, a ladder is fixedly connected to the rear surface of the operating room 2, and an opening and closing door is hinged to the rear surface of the operating room 2.

[0041] The above technical solution allows staff to easily enter the control room 2 to perform operations.

[0042] In operation, when the gate needs to be opened, the first motor 301 is started, driving the first helical gear 302 to rotate, which in turn drives the second helical gear 303 and the inner groove tube 304 to rotate. This causes the lead screw 305 to move upward, which in turn drives the gate assembly to rise, thus opening the gate and releasing water. When the dam 308 needs to be replaced, the pin 5 is pulled out and the limit block 4 is then pulled out of the dam 308 to replace it. During normal water release, the filter screen 66 in the filtration mechanism 6 filters the water from the river. When water passes through the sluice gate, floating garbage and debris in the river can be intercepted at a distance away from the sluice gate 308. At the same time, the floating garbage and debris will accumulate in front of the filter screen 66. The filter screen will not leave the water surface with the gate. When the gate is opened to release water, the filter screen can keep intercepting floating objects, which is convenient for staff to carry out unified retrieval later. When it is necessary to open the gate to release floodwater, the second motor 61 is started to drive the drum 63 to rotate, and the hoisting rope 64 is wound up, thereby pulling the filter screen 66 up, avoiding excessive accumulation of garbage and debris in front of the filter screen 66 and affecting the water release speed.
