Description

Technical Field

[0001] The utility model belongs to the field of gate scouring and silting, and in particular relates to a flood control gate scouring and silting device. Background Art

[0002] The flood control gate silt flushing device is a device used to clean the silt and fine soft debris in front of the gate. The following are several common flood control gate silt flushing devices: (1) High-pressure water gun flushing device: The high-speed water flow generated by the high-pressure water gun is used to flush the silt in front of the gate and wash away the silt. (2) Suction dredger equipment: The silt in front of the gate is sucked away by a suction dredger.

[0003] However, at some gates that are not frequently used, the silt has been deposited for a long time and has been subjected to a certain degree of squeezing, dehydration, etc., and may harden to a certain extent. According to the above-mentioned current mainstream silt clearing methods, it is only suitable for the relatively soft silt that has just been deposited. However, if the silt is accumulated more and thicker, or has been deposited and compacted for a period of time, it will not be so easy to be completely washed away or sucked away. Only part of the surface will be removed or the silt will be loosened, which will result in poor actual silt flushing effect or too slow effect, which may affect the normal opening and closing of the gates, and may even affect the safety of the building in an emergency.

[0004] Therefore, it is necessary to provide a flood control gate silt flushing device that can improve the silt flushing effect. Utility Model Content

[0005] The embodiment of the utility model provides a flood control gate silt flushing device, which is applicable to an exposed top gate or a downstream breast wall submerged hole gate, and is used to solve the problems in the prior art.

[0006] The embodiment of the utility model adopts the following technical scheme: a flood control gate silt flushing device, including a gate pier and a gate, the gate moves up and down along the gate slot on the gate pier to realize the opening and closing of the gate; it also includes a sliding frame, a slider and a plurality of mud knives, the sliding frame is supported on the slide slot on the upstream side of the gate, slides in the slide slot in the vertical direction, and the slide slot is arranged in the gate pier; the slider is slidably connected to the sliding frame in the horizontal direction, the lower side end of the slider is rotatably connected to a rotating shaft driven to rotate by power, and a plurality of mud knives are evenly distributed on the outside of the rotating shaft; a position adjustment component is provided between the slider and the sliding frame for adjusting the relative position of the slider and the sliding frame; a water pipe rack is also fixedly installed on one side of the sliding frame, and a plurality of high-pressure nozzles are evenly arranged on the water pipe rack, and the spraying direction of the high-pressure nozzle is inclined downward to point to the bottom of the sliding frame.

[0007] Preferably, each mud paddle is provided with an inclined cutting edge at the outer end thereof.

[0008] Preferably, at least one cone thorn is symmetrically provided on opposite sides of each group of adjacent plastering knives, and the cone thorn is located at the end portion of the plastering knives.

[0009] Preferably, two connecting plates are arranged at the lower end of the slider, and the two ends of the rotating shaft respectively pass through the two connecting plates and rotate together therewith, and a waterproof motor is installed on one of the connecting plates, and the output shaft of the waterproof motor is drivingly connected to the rotating shaft.

[0010] Preferably, two groups of through grooves are provided at the upper end of the sliding frame, a sliding portion is formed between the two groups of through grooves and slidably cooperates with the through holes on the slider; the position adjustment component includes at least one latch, each latch is provided with a limit plate at the top end, and the sliding portion has a plurality of first sockets equidistantly distributed along the sliding direction of the slider; the latch passes through the second socket on the slider and is inserted into one of the first sockets, and the locking of the slider and the sliding frame is achieved by limiting the position of the limit plate.

[0011] Preferably, the high-pressure nozzle is supplied with water by a water pump.

[0012] Preferably, a top support beam is also installed at the top of the gate pier, and an electric winch is installed on the top support beam. The winch realizes the lifting and lowering of the sliding frame through the traction of a steel wire rope.

[0013] Preferably, the front side of the winch is also provided with a steering fixed pulley for guiding the wire rope.

[0014] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0015] Firstly, the utility model slides the sliding frame up and down to the upper part of the compacted and hardened silt, so that a number of mud blades are located in the silt. As the rotating shaft rotates, the mud blades are driven to rotate, thereby loosening the silt layer by layer. Then, the secondary impact of the silt on the riverbed and the gate panel by the water flow sprayed from the high-pressure nozzle can be combined. In addition, the position of the entire mud blade can be adjusted through the position adjustment component, that is, the mud blade can be adjusted along the width direction of the gate to ensure that the mud blade can move within the entire aperture range and fully break up the silt. After the above treatment, the gate silt pressure and the friction caused by it are greatly reduced, which can significantly reduce the gate opening and closing force. At the same time, after the gate is opened to release water, it is easier to wash away the dispersed silt with the outflow of water, avoiding further accumulation and compaction of the silt in front of the gate;

[0016] Secondly, the utility model can be used when the gate does not need to be opened for a long time. The sluice gate manager can regularly use the above method to move a number of mud knives to the bottom of the water area. The rotation of the mud knives can disturb the flow of water at the bottom of the water area to avoid the deposition of silt. For a small amount of silt deposition, the silt can also be broken up under the rotation of the mud knives to avoid long-term accumulation and hardening of the silt, which will affect the normal opening of the gate at a later time.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Reference Figures 1 to 5 As shown, the embodiment of the utility model provides a flood control gate silt flushing device, which is suitable for an exposed top gate or a downstream breast wall submerged hole gate, comprising a gate pier 1 and a gate 2, wherein the gate 2 moves up and down along a gate slot 11 on the gate pier 1 to realize the opening and closing of the gate, specifically, the gate is moved up and down by a gate hoist to control the opening and closing of the gate, and reference can be made to the opening and closing method of the exposed top gate (which is a conventional technology and will not be described in detail); the flood control gate silt flushing device also includes a sliding frame 3, a sliding block 4 and a plurality of mud knives 5, wherein the sliding frame 3 is supported on a slide slot 12 on the upstream side of the gate 2 and slides in the slide slot in a vertical direction, and the slide slot (12) is buried in the gate pier (1);

[0028] The slider 4 is slidably connected to the sliding frame 3 in the horizontal direction, and the lower side end of the slider 4 is rotatably connected to a rotating shaft 41 driven to rotate by power, and a plurality of mud paddles 5 are evenly distributed on the outside of the rotating shaft 41. Specifically, two connecting plates 42 are arranged at the lower end of the slider 4, and the two ends of the rotating shaft 41 pass through the two connecting plates 42 respectively and rotate with them. A waterproof motor 43 is installed on one of the connecting plates 42, and the output shaft of the waterproof motor 43 is drivingly connected to the rotating shaft 41, so as to realize the driving rotation of the rotating shaft 41 and the plurality of mud paddles 5;

[0029] A position adjustment component 6 is provided between the slider 4 and the sliding frame 3, and is used to adjust the relative position of the slider 4 and the sliding frame 3. A water pipe rack 31 is also fixedly installed on one side of the sliding frame 3, and a plurality of high-pressure nozzles 32 are evenly arranged on the water pipe rack 31. The spraying direction of the high-pressure nozzle 32 is tilted downward to point to the bottom of the sliding frame 3. The high-pressure nozzle 32 is supplied with water by a water pump (the water pump is a prior art and is not shown in the figure). The water in the upper layer of the water body is sucked by the water pump and transported to the high-pressure nozzle 32 for spraying, so as to flush the silt on the front side of the gate 2.

[0030] When the gate is in a closed state, the flow of the upstream water area will cause the sediment and silt to accumulate on the upstream side of the gate 2. If the gate is in a closed state for a long time, the silt will accumulate and harden, increasing the friction resistance when the gate is opened and closed. Therefore, before or after the gate is opened, the sliding frame 3 slides downward to the bottom of the water area, so that the plurality of mud knives 5 are in the silt. As the rotating shaft 41 rotates, the plurality of mud knives 5 rotate to loosen the silt, and then the high-pressure nozzle 32 sprays water to the silt. The secondary impact can make the silt separate from the riverbed. In addition, the position of the overall mud blade 5 can be adjusted by the position adjustment component 6, that is, the mud blade 5 can be adjusted along the width direction of the gate to ensure that the mud blade 5 can fully break up the silt. After the above treatment, the gate silt pressure and the friction caused by it are greatly reduced, which can significantly reduce the gate opening and closing force. After the gate is opened to release water, it is easier to wash away the dispersed silt with the outflow of water, avoiding further accumulation and compaction of silt in front of the gate. At the same time, it avoids problems such as uneven force and deformation of the gate structure due to siltation, reduces the risk of damage to the gate and related facilities, and extends its service life.

[0031] In addition, when the gate does not need to be opened for a long time, the sluice gate management personnel can regularly use the above method to move a number of mud blades 5 to the bottom of the water area. The rotation of the mud blades 5 can disturb the flow of water at the bottom of the water area to avoid the deposition of silt. For a small amount of silt deposition, the silt can also be broken up under the rotation of the mud blades 5 to avoid long-term accumulation and hardening of the silt, which affects the normal opening of the gate in the later period.

[0032] In one embodiment, if Figure 2 and Figure 3 As shown, two groups of through grooves 33 are provided at the upper end of the sliding frame 3, and a sliding portion 34 is formed between the two groups of through grooves 33 and slidably cooperates with the through holes 44 on the slider 4; the position adjustment component 6 includes at least one latch 61, and a limit plate 62 is provided at the top of each latch 61, and the sliding portion 34 has a plurality of first plug holes 341 equidistantly distributed along the sliding direction of the slider 4; the latch 61 passes through the second plug hole 45 on the slider 4 and is inserted into one of the first plug holes 341, and the slider 4 and the sliding frame 3 are locked by limiting the limit plate 62.

[0033] In this embodiment, two latches 61 are provided. Before the sliding frame 3 is launched into the water, the staff can pull out both latches 61 in advance, change the position of the slider 4 (the position of the mud blade 5 is also changed accordingly), and then insert the latches 61 into the corresponding first plug hole 341 and second plug hole 45 to adjust the position of the mud blade 5, so as to facilitate all-round cleaning of the silt on the upstream side of the gate.

[0034] In another embodiment, if Figure 2and Figure 4 As shown, each mud paddle 5 is provided with an inclined cutting edge 51 at the outer end thereof, and the cutting edge 51 can increase the sharpness of the mud paddle 5, so that the deposited sludge can be more easily broken up. In addition, considering that there is a certain interval between each group of adjacent mud paddles 5, the sludge between the mud paddles 5 may not be broken up. For this purpose, at least one cone thorn 52 is symmetrically provided on the opposite sides of each group of adjacent mud paddles 5, and the cone thorn 52 is located at the end of the mud paddle 5. When the rotating shaft 41 rotates, the cone thorn 52 rotates with the mud paddle 5. The sludge can be completely broken up by the collision and scraping of the sludge by the cone thorn 52.

[0035] Specifically, a top support beam 13 is also installed at the top of the gate pier 1, and an electric winch 14 is installed on the top support beam 13. The winch 14 realizes the lifting and lowering of the sliding frame 3 by pulling of a steel wire rope 15. The front side end of the winch 14 is also provided with a steering fixed pulley 16 for guiding the steel wire rope 15. The winch 14 and the steel wire rope 15 are used to realize the lifting and lowering of the sliding frame 3, so that the driving part is always located above the water area to avoid damage to the driving source by the water body, and because the steel wire rope 15 pulls the sliding frame 3 only by relying on the gravity of the sliding frame 3 and a plurality of mud knives 5 to achieve height adjustment, when the mud knives 5 just contact the deposited and hardened silt, as the mud knives 5 rotate, the sliding frame 3 and the plurality of mud knives 5 will jump up and down in a certain longitudinal space. In this way, for harder silt blocks, rigid contact will not cause damage to the mud knives 5, but a jumping method will be used to slowly break up the silt.

[0036] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
