Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and specifically, to a gate provided with a water passage. Background Art

[0002] The construction of the gate has a physical blocking effect on the upstream and downstream reaches of the river channel. It artificially cuts off the originally smooth water flow. On the one hand, the blocking of the gate causes a water level drop between the upstream and downstream of the river. When the water level overflows upstream of the gate, due to the large falling height of the water, it is easy to generate a large amount of noise, affecting the normal rest of the surrounding residents. On the other hand, due to the destruction of the river continuum, for fish, for reasons such as foraging, breeding, and overwintering, most fish need to swim freely in the upstream and downstream river channels according to their natural habits. After the construction of the gate, due to the objective factor of the gate intercepting the river channel, fish cannot swim freely over the gate, hindering fish from swimming back to the spawning ground upstream of the reservoir for spawning and hindering some fish from returning to the sea, which has a serious impact on the growth and reproduction of fish. Moreover, the gate itself has a certain natural vibration frequency. When discharging water, if the pulsation frequency of the water flow is close to or equal to its own natural vibration frequency, resonance will occur, resulting in strong vibration of the whole or part of the gate. In severe cases, it may cause fatigue deformation of metal components, weld cracking, or loosening of fasteners, so that the overall structure of the gate is damaged, which poses a safety hazard to the water conservancy project and the gate is prone to malfunction. In addition, after the gate operates for a certain period of time, sedimentation may occur on both the upstream side and the downstream side, thus affecting the normal use of the gate.

[0003] In view of the above problems, the Chinese utility model patent CN215758867U discloses a gate, which opens a water passage with a small water level drop near the bottom shaft of the gate, and sets a driving device and a movable water stop device for opening or closing the water passage, so that the water flow passes through the water passage from the upstream to the downstream. Its defect lies in that: in this scheme, the driving device drives the movable water stop device to move along the direction of the water flow, which causes the driving device to be set in the river channel, far from the shore and inconvenient for maintenance; and, through this driving method, the number of movable water stop devices that a driving device can drive is extremely limited. Therefore, in the case of a large number of movable water stop devices, multiple sets of driving devices need to be set in the river channel, and the project cost is relatively high. Summary of the Invention

[0004] Aiming at the defects in the prior art, the purpose of the present invention is to provide a gate provided with a water passage, which has a relatively simple structure, a low project cost, and is convenient for maintenance.

[0005] According to the gate provided with a water passage of the present invention, it includes a gate leaf, a first driving device, a water passage, and an opening and closing device;

[0006] The channel entrance of the water passage leads to the upstream side of the gate leaf, and the channel exit of the water passage leads to the downstream side of the gate leaf; the first driving device drives the gate leaf to open or close; the opening and closing device includes a second driving device and an opening and closing door, the second driving device is connected to the opening and closing door, and the second driving device drives the opening and closing door to make a horizontal linear reciprocating motion, so as to open or close the water passage.

[0007] In this technical solution, by adopting the above-mentioned structural design, the second driving device drives the opening and closing door to make a horizontal linear reciprocating motion, and the water passage can be opened or closed with a relatively simple structure. Moreover, the second driving device can be arranged on the bank or near the bank, which is convenient for maintenance compared with the prior art. Among them, the so-called "horizontal" means that the moving direction of the opening and closing door 52 is perpendicular to or forms a certain angle with the moving direction of the water flow on the horizontal plane, or in other words, the opening and closing door 52 does not move along the water flow direction.

[0008] Preferably, it further includes a driving device chamber, the driving device chamber is located on the side of the gate leaf, and the first driving device and the second driving device are arranged in the driving device chamber.

[0009] Preferably, the number of the opening and closing doors and the water passages is not less than two, and the opening and closing doors are connected by a first linkage structure, and the second driving device drives each opening and closing door to move, so as to open or close each water passage.

[0010] Preferably, it further includes a second linkage structure, one end of the second linkage structure is connected to the second driving device, and the other end is connected to the opening and closing door, and the second driving device drives the opening and closing door to open or close the water passage through the second linkage structure.

[0011] Preferably, the second driving device drives the opening and closing door to open or close the channel entrance or the channel exit of the water passage.

[0012] Preferably, the number of the opening and closing devices is at least two, and the opening and closing devices are arranged on both sides of the gate leaf.

[0013] Preferably, it further includes a bottom shaft, the bottom shaft is located at the bottom of the gate leaf, and the first driving device drives the gate leaf to open or close through the bottom shaft.

[0014] Preferably, the second driving device is a hydraulic cylinder.

[0016] Preferably, a trash rack device is arranged upstream of the channel entrance, and the trash rack device includes a grille.

[0017] Preferably, it further includes a protective grille, and the protective grille is arranged above the opening and closing device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. For the gate provided with a water passage in the present invention, by setting a very small number of second driving devices and a linkage structure, synchronous control of multiple opening and closing doors can be achieved. Compared with the prior art, the structure is simplified and the project cost is reduced;

[0020] 2. For the gate provided with a water passage in the present invention, a relatively unique driving method is adopted, and the second driving device can be arranged in the driving device chamber, avoiding the loss of the second driving device caused by the scouring of substances such as water flow and sediment, thereby increasing the service life of the second driving device. And because the second driving device is arranged in the driving device chamber, the maintenance is more convenient;

[0022] 4. For the gate provided with a water passage in the present invention, during the process of water flowing in the water passage, the water passage and the upstream and downstream areas of the gate can be scoured and dredged, thereby avoiding the influence of sediment deposition on the normal operation of the gate or causing the blockage of the water passage;

[0023] 5. For the gate provided with a water passage in the present invention, when the water passage is opened, fish in the river can pass through the water passage to migrate from downstream of the gate to upstream of the gate;

[0024] 6. For the gate provided with a water passage in the present invention, since water can flow through the water passage, the vibration during the gate's water discharge can be effectively reduced, and the potential safety hazards during the use of the gate are reduced.

[0048] First Embodiment:

[0049] As Figures 1 to 5 shown, this embodiment provides a gate provided with a water passage 6, including a gate leaf 1, a bottom shaft 2, a drive device chamber 3, and an opening and closing device 5.

[0050] Specifically, the passage inlet 61 of the water passage 6 leads to the upstream side of the gate leaf 1, and the passage outlet 62 of the water passage 6 is located on the downstream side of the gate leaf 1. The bottom shaft 2 is located at the bottom of the gate leaf. A first drive device 4 is provided in the drive device chamber 3. The first drive device 4 is connected to the bottom shaft 2 and drives the gate to open or close through the bottom shaft 2. It should be noted that in this embodiment, the bottom shaft 2 is provided at the bottom of the gate leaf 1, while in other embodiments, the bottom shaft 2 may not be provided, so that the technical solutions in the present invention can be applied to other gate types. Regarding the specific form of the first drive device 4, it can be set according to actual situations. In this embodiment, the first drive device 4 is set as a hydraulic cylinder.

[0051] Regarding the structure of the opening and closing device 5, it includes a second drive device 51 and an opening and closing door 52. The second drive device 51 is provided in the drive device chamber 3, and a first linkage structure 53 is connected to one end of the second drive device 51. Regarding the structure of the second drive device 51, it can be set according to actual needs. In this embodiment, the second drive device 51 is set as a hydraulic cylinder. The first linkage structure 53 passes through the drive device chamber 3 and is connected to the opening and closing door 52. Regarding the first linkage structure 53, in this embodiment, the first linkage structure 53 is a linkage rod. Regarding the movement direction of the opening and closing door 52, in this embodiment, the second drive device 51 drives the opening and closing door 52 to perform a linear reciprocating motion perpendicular to the water flow direction, while in other embodiments, the movement direction of the opening and closing door 52 can also be set to be not perpendicular to the water flow direction but inclined to the water flow direction.

[0052] Regarding the structures of the opening and closing doors 52 and the water passage 6, their numbers are equal. In this embodiment, the numbers of both the opening and closing doors 52 and the water passage 6 are three, and each opening and closing door 52 is used to open or close the corresponding water passage 6. It should be noted that the numbers of the opening and closing doors 52 and the water passage 6 can be set according to actual needs. For example, in other embodiments, only one water passage 6 and the opening and closing door 52 can also be set. The opening and closing doors 52 are connected into a whole through the second linkage structure 54. The second linkage structure 54 enables the opening and closing doors 52 to move synchronously as a whole without relative displacement. Regarding the second linkage structure 54, in this embodiment, the second linkage structure 54 is a linkage rod.

[0053] Regarding the positions of the opening and closing doors 52 and the water passage 6, in this embodiment, the opening and closing doors 52 are arranged on the upstream side of the gate leaf 1 and at the channel entrance 61. The second driving device 51 drives the opening and closing doors 52 to open or close the channel entrance 61 of the water passage 6 through the first linkage structure 53.

[0054] Figure 4 The first state diagram of the gate provided in this embodiment with the water passage 6 is shown. At this time, the opening and closing door 52 is located at the channel entrance 61 of the water passage 6 and blocks the channel entrance 61, and the water passage 6 is in a closed state.

[0055] Figure 5 The second state diagram of the gate in this embodiment is shown. At this time, the second driving device 51 drives each opening and closing door 52 to move synchronously outside the channel entrance 61 through the second linkage structure 54. Thus, the channel entrance 61 is opened, and the water flow passes through the water passage 6 from the upstream of the gate leaf 1 to the downstream of the gate leaf 1.

[0056] Such a structural design can achieve the following: First, by setting a very small number of second driving devices 51 and linkage structures, the synchronous driving of multiple opening and closing doors 52 can be realized, which simplifies the structure compared with the prior art and reduces the project cost; Second, by adopting the solution of this embodiment, the second driving device 51 can be arranged in the driving device chamber 3, avoiding the loss of the second driving device 51 caused by the scouring of substances such as water flow and sediment, thus greatly improving the service life of the second driving device 51, and the second driving device 51 is arranged in the driving device chamber 3, making maintenance more convenient; Third, since the water flow drop at the channel entrance 61 and the channel exit 62 is small, basically no noise is generated during the flowing process; Fourth, the water flow can scour and silt the water passage 6 during the flowing process in the water passage 6, thus avoiding the blockage of the water passage 6; Fifth, the fish in the river can migrate from the downstream of the gate leaf 1 to the upstream of the gate leaf 1 through the water passage 6; Sixth, since the water flow flows through the water passage 6, the vibration during the gate's water discharge can be effectively reduced, thus reducing the potential safety hazards during the use of the gate.

[0057] Further, the gate provided in this embodiment and equipped with a water passage 6 further includes a track. The opening and closing door 52 can move along the track under the action of the second driving device 51, thereby opening or closing the water passage 6. Regarding the specific structure of the track, it can be set according to actual situations. For example, it can be set as two channel steels, and each opening and closing door 52 slides along the channel steel to open or close the water passage 6. Such a structural design can make the movement process of the opening and closing door 52 smoother and the positioning more accurate, so as to better open or close the water passage 6.

[0058] Embodiment 2:

[0059] As Figure 6 shown, this embodiment provides a gate equipped with a water passage 6, which has a substantially the same structure as the gate equipped with a water passage 6 in the first embodiment. The difference is that in the first embodiment, the opening and closing device 5 is arranged on one side of the gate leaf 1, while in this embodiment, the opening and closing device 5 is arranged on both sides of the gate leaf 1.

[0060] Specifically, there are two second driving devices 51, which are respectively arranged in the driving device chambers 3 on both sides of the gate leaf 1. Each second driving device 51 is respectively connected to the opening and closing door 52 through a first linkage structure 53. Regarding the number of opening and closing doors 52 on both sides of the gate leaf 1, it can be set according to actual situations. In this embodiment, a plurality of opening and closing doors 52 are respectively arranged on both sides, and the opening and closing doors 52 are connected through a second linkage structure 54.

[0061] Embodiment 3:

[0062] This embodiment provides a gate equipped with a water passage 6, which has a substantially the same structure as the gate equipped with a water passage 6 in the first embodiment. The difference is that the gate provided in this embodiment and equipped with a water passage 6 is further provided with a trash rack device and a protective grille.

[0063] Specifically, the trash rack device is arranged upstream of the channel entrance 61. The setting of the trash rack device can prevent the garbage in the river from entering the water passage 6 and causing blockage of the water passage 6. In addition, the grid pitch of the trash rack device grille can be determined in combination with the need for fish passage to ensure that the migration of fish is unobstructed. Regarding the protective grille, the protective grille is arranged above the opening and closing device 5 to provide protection for the opening and closing device 5.

[0064] The specific embodiments of the present invention are described above. Through the above description, relevant staff can make various changes and modifications completely within the scope not deviating from the technical idea of this invention.
