Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a gate cleaning device for water conservancy projects. Background Technology

[0002] Currently, water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. They are also known as water engineering projects. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production.

[0003] Because sluice gates are in constant contact with water, a lot of deposits accumulate on their surface over time. If they are not cleaned in a timely and effective manner, this can lead to corrosion and even render the gates unusable. To address this issue, some sluice gates are equipped with filters, but these filters are usually non-removable and cannot be replaced. Manual cleaning of the sluice gates is not only time-consuming and labor-intensive but also poses safety hazards. For example, patent CN222198008U requires an additional power source to drive a scraper for cleaning the sluice gate. To address these problems, a sluice gate cleaning device for water conservancy projects is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a gate cleaning device for water conservancy projects. It solves the problem that, due to long-term contact with water, many deposits accumulate on the surface of the gate over time. If not cleaned in a timely and effective manner, this can lead to corrosion or even the failure of the gate. To solve this problem, some gates are equipped with filters, but these filters are usually non-removable and cannot be replaced. Manual cleaning of the gate is not only time-consuming and laborious, but also poses safety hazards. For example, the patent CN222198008U requires the addition of a power source to drive a scraper to clean the gate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a gate cleaning device for water conservancy projects, including a gantry frame, with limit grooves on both the left and right side walls inside the gantry frame, a gate body slidably connected between two sets of limit grooves, racks fixedly connected to both the left and right ends of the front side of the gate body, a lifter fixedly installed at the middle position of the top of the gantry frame, a lifting screw threadedly connected to the middle of the lifter, connecting ears fixedly connected to both the left and right sides of the top of the gate body, a fixing rod fixedly connected between two sets of connecting ears, a connecting seat fixedly connected to the top of the fixing rod, the bottom end of the lifting screw passing through the top of the gantry frame and fixedly connected to the inside of the connecting seat, and a cleaning component fixedly installed at the middle of the front side of the gantry frame.

[0006] Preferably, the cleaning assembly includes two sets of rotating seats, which are respectively fixedly connected to the left and right ends of the front side of the gantry frame. A transmission rod is rotatably connected between the two sets of rotating seats, and a cleaning roller is fixedly connected to the middle of the transmission rod.

[0007] Preferably, the cleaning roller abuts against the front side of the gate body, and gears are fixedly connected to the outer surface of the transmission rod and both ends of the cleaning roller. The two sets of gears mesh with the two sets of racks respectively, and the right end of the transmission rod passes through the right rotating seat and is fixedly connected to the first synchronous pulley.

[0008] Preferably, the cleaning component further includes a limiting block and an mounting block. The limiting block is fixedly connected to the left front end of the gantry frame, and the mounting block is fixedly connected to the right front end of the gantry frame. A swing rod is slidably connected inside the limiting block, and a sliding groove is provided at the upper end of the mounting block. A sliding block is slidably connected inside the sliding groove, and the right end of the swing rod is fixedly connected to the left side of the sliding block.

[0009] Preferably, a rotating groove is provided at the bottom of the mounting block, a rotating cylinder is rotatably connected inside the rotating groove, a cam groove is provided on the outer surface of the rotating cylinder, and the lower end of the sliding block is slidably connected to the inside of the cam groove by ball bearings.

[0010] Preferably, the right side of the rotating cylinder is fixedly connected to the outside of the mounting block via a rotating shaft, and the second synchronous pulley is connected to the first synchronous pulley via a synchronous belt.

[0011] Preferably, a cleaning brush is fixedly connected to the middle of the outer surface of the swing rod, and two sets of limiting strips are fixedly connected to the left side surface of the swing rod. The limiting block has a groove adapted to the limiting strip inside, and the limiting strip is slidably connected to the inside of the groove.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. This utility model uses a rack and pinion mechanism to drive a transmission rod to rotate, which in turn drives a cleaning roller to clean the surface of the gate body. The rotation of the cylinder drives the cam groove to rotate. Since the lower end of the sliding block is slidably connected to the inside of the cam groove by ball bearings, the sliding block slides left and right inside the sliding groove, which in turn drives the swing rod to swing left and right. The rotating roller can effectively perform preliminary physical cleaning, especially suitable for removing larger particles of mud, algae, or debris. The friction generated by the rotation of the roller can easily brush away most of the loose material attached to the gate surface. The reciprocating cleaning brush can perform a more refined cleaning of the gate surface, reaching into crevices or corners that the roller cannot reach, removing more stubborn dirt or grime, ensuring a thorough cleaning. The dual action of the rotating roller and the brush can effectively remove dirt that has accumulated for a long time, keeping the gate in a cleaner state.

[0014] 2. This utility model has a simple structure and reasonable design. It does not require an additional device to power the cleaning components. The surface of the gate can be cleaned simply by opening and closing the gate. Cleaning is achieved by utilizing the opening and closing action of the gate. No independent power supply is required, which reduces power consumption and operating costs, effectively saves energy, and is environmentally friendly. The cleaning process is synchronized with the operation of the gate. No additional manual intervention or manual start of the cleaning equipment is required. The operator only needs to monitor the normal opening and closing action of the gate, which simplifies the operation process. Attached Figure Description

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Reference Figure 1-7 As shown, a gate cleaning device for a water conservancy project includes a gantry frame 1. Limiting grooves 2 are provided on both the left and right side walls inside the gantry frame 1. The limiting grooves 2 restrict the movement trajectory of the gate body 3, ensuring that it can slide smoothly up and down inside the gantry frame 1. The gate body 3 is slidably connected between the two sets of limiting grooves 2. The left and right ends of the front side of the gate body 3 are fixedly connected to racks 4. A lifting device 9 is fixedly installed at the middle position of the top of the gantry frame 1. A lifting screw 8 is threadedly connected to the middle of the lifting device 9. The working principle of the lifting device 9 is existing technology and will not be described in detail here. The left and right sides of the top of the gate body 3 are fixedly connected to connecting ears 5. A fixing rod 6 is fixedly connected between the two sets of connecting ears 5. A connecting seat 7 is fixedly connected to the top of the fixing rod 6. The bottom end of the lifting screw 8 passes through the top of the gantry frame 1 and is fixedly connected to the inside of the connecting seat 7. A cleaning component 10 is fixedly installed at the middle of the front side of the gantry frame 1.

[0026] Furthermore, the cleaning component 10 includes two sets of rotating seats 1001, which are fixedly connected to the left and right ends of the front side of the gantry frame 1, respectively. A transmission rod 1002 is rotatably connected between the two sets of rotating seats 1001. A cleaning roller 1003 is fixedly connected to the middle of the transmission rod 1002. The height of the cleaning component 10 is set above the water surface, which can be set to 30 centimeters above the water surface. This can prevent transmission components such as gears 1004 from being immersed in water and causing rust. Setting it above the water surface also makes it convenient for staff to carry out maintenance.

[0027] In one embodiment, the cleaning roller 1003 abuts against the front side of the gate body 3. Gears 1004 are fixedly connected to the outer surface of the transmission rod 1002 and both ends of the cleaning roller 1003. The two sets of gears 1004 mesh with the two sets of racks 4 respectively. The right end of the transmission rod 1002 passes through the right rotating seat 1001 and is fixedly connected to the first synchronous wheel 1005. The transmission rod 1002 rotates through the meshing of the gears 1004 and the racks 4, thereby driving the cleaning roller 1003 to clean the gate body 3.

[0028] Furthermore, the cleaning component 10 also includes a limiting block 1013 and a mounting block 1006. The limiting block 1013 is fixedly connected to the front left end of the gantry frame 1, and the mounting block 1006 is fixedly connected to the front right end of the gantry frame 1. A swing rod 1014 is slidably connected inside the limiting block 1013. A sliding groove 1010 is opened at the upper end of the mounting block 1006. A sliding block 1011 is slidably connected inside the sliding groove 1010. The right end of the swing rod 1014 is fixedly connected to the left side of the sliding block 1011.

[0029] Preferably, a rotating groove 1007 is provided at the lower part of the mounting block 1006, and a rotating cylinder 1008 is rotatably connected inside the rotating groove 1007. A cam groove 1009 is provided on the outer surface of the rotating cylinder 1008. The lower end of the sliding block 1011 is slidably connected to the cam groove 1009 through a ball. The cam groove 1009 on the rotating cylinder 1008 cooperates with the ball at the lower end of the sliding block 1011 to realize the reciprocating swing of the swing rod 1014.

[0030] Furthermore, a second synchronous pulley 1012 is fixedly connected to the outside of the mounting block 1006 via a rotating shaft on the right side of the rotating cylinder 1008. The second synchronous pulley 1012 is connected to the first synchronous pulley 1005 via a synchronous belt. The synchronous belt transmits the rotation of the first synchronous pulley 1005 to the second synchronous pulley 1012, thereby driving the rotating cylinder 1008 to rotate.

[0031] Specifically, a cleaning brush 1015 is fixedly connected to the middle of the outer surface of the swing rod 1014, and two sets of limiting strips 1016 are fixedly connected to the left side surface of the swing rod 1014. The limiting block 1013 has a groove inside that matches the limiting strip 1016. The limiting strip 1016 is slidably connected inside the groove. The bristles of the cleaning brush 1015 are set long enough so that the cleaning brush 1015 can fully contact the surface of the gate body 3. While the cleaning brush 1015 swings back and forth, it can also clean the rack 4, preventing impurities from accumulating inside the tooth groove of the rack 4. The setting of the limiting strip 1016 can prevent the swing rod 1014 from rotating during reciprocating swing, causing the cleaning brush 1015 to tilt and fail to contact the surface of the gate body 3.

[0032] Working principle: When the gate is being cleaned, the lifting device 9 operates by changing the height of the lifting screw 8 through a threaded connection. This, in turn, pulls the gate body 3 downward within the limiting groove 2 via the connecting seat 7, fixing rod 6, and connecting lug 5. As the gate body 3 moves upward, the meshing of the rack 4 and gear 1004 drives the transmission rod 1002 to rotate, which in turn drives the cleaning roller 1003 to rotate, cleaning the surface of the gate body 3. Simultaneously, the rotation of the transmission rod 1002 drives the first synchronous pulley 1005 to rotate, which in turn drives the second synchronous pulley 1005 via a synchronous belt. When the second synchronous wheel 1012 rotates, the rotation of the second synchronous wheel 1012 will be transmitted to the rotating cylinder 1008 through the rotating shaft. When the rotating cylinder 1008 rotates, the cam groove 1009 on its surface will also rotate. Since the lower end of the sliding block 1011 is slidably connected to the inside of the cam groove 1009 through the ball bearing, the sliding block 1011 will slide left and right inside the sliding groove 1010, thereby driving the swing rod 1014 to swing left and right, so as to use the cleaning brush 1015 to clean the surface of the gate body 3. Similarly, the gate body 3 can also be cleaned when it moves downward.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
