Description

Technical Field

[0001] This utility model relates to the field of hydraulic grid technology, and in particular to a hydraulic grid that is easy to assemble and install. Background Technology

[0002] Hydraulic bar screens, as key pretreatment equipment in water conservancy projects and water treatment systems, play a vital role and significance throughout the entire process of water resource development, utilization, and management. They not only ensure the safe operation of projects but also have important value for ecological protection and human health. Hydraulic bar screens can be used in reservoirs, lakes, or medium-sized rivers with slow water flow to intercept floating debris, aquatic plant remains, silt clumps, etc., as well as in sewage treatment plant screens and storm drain screens.

[0003] While hydraulic screens intercept impurities, impurities such as tree branches and plastic bags may also enter the channels on the screen. These impurities can become stuck inside the channels, affecting the normal use of the hydraulic screen. Over time, this accumulation can slow down the water flow. Therefore, hydraulic screens need to be cleaned frequently. However, most existing hydraulic screens are one-piece designs, which are inconvenient to clean. Workers find it difficult to remove impurities stuck at the bottom, requiring a lot of manpower. Furthermore, if a hydraulic screen is damaged, the entire unit must be replaced, resulting in some waste. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic screen that is easy to assemble and install, in order to solve the problem that most existing hydraulic screens are one-piece and cannot be disassembled, and that it is difficult to clean when impurities are stuck inside the channel of the hydraulic screen, resulting in high labor costs.

[0005] To achieve the above objectives, a hydraulic screen that is easy to assemble and install is provided, comprising: an outer frame; a slot is provided inside the outer frame; an insert block is movably connected to the inner surface of the slot; a screen body is fixedly connected inside the insert block; a through groove is provided inside the screen body; a first connecting block is fixedly connected to the front surface of the outer frame; a fixing rod is rotatably connected inside the first connecting block; a second connecting block is fixedly connected to the outer surface of the fixing rod; and limit blocks are fixedly connected to both ends of the fixing rod.

[0009] According to the hydraulic grid that is easy to assemble and install, the lower surface of the top plate is in contact with the outer frame, and the lower surface of the top plate is in contact with the insert block.

[0010] According to the hydraulic grid that is easy to assemble and install, the front surface of the fixing block is in contact with the top plate, and the front surface of the lever block is in contact with the fixing block.

[0011] According to the hydraulic grid that is easy to assemble and install, the right surface of the first connecting block is slidably connected to the second connecting block, and the right surface of the limiting block is slidably connected to the first connecting block.

[0012] According to the hydraulic grid that is easy to assemble and install, the inner surface of the outer frame is in contact with the grid body, and the number of through slots is multiple and distributed in a linear array.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model provides a hydraulic grid that is easy to assemble and install. It includes an outer frame 1, a slot 2 inside the outer frame 1, an insert block 3 movably connected to the inner surface of the slot 2, a grid body 4 fixedly connected inside the insert block 3, the inner surface of the outer frame 1 contacting the grid body 4, a through groove 5 inside the grid body 4, the number of through grooves 5 being multiple and arranged in a linear array, a first connecting block 6 fixedly connected to the front surface of the outer frame 1, a fixing rod 7 rotatably connected inside the first connecting block 6, a second connecting block 8 fixedly connected to the outer surface of the fixing rod 7, the right surface of the first connecting block 6 being slidably connected to the second connecting block 8, and limit blocks 9 fixedly connected to both ends of the fixing rod 7, the right surface of the limit blocks 9 being slidably connected to the first connecting block 6.

[0025] A top plate 10 is fixedly connected to the second connecting block 8. The lower surface of the top plate 10 contacts the outer frame 1 and the insert block 3. A fixing block 11 is fixedly connected to the rear surface of the outer frame 1. The front surface of the fixing block 11 contacts the top plate 10. There are two fixing blocks 11, which are arranged left and right. A sliding groove 12 is provided inside the fixing block 11. A locking block 13 is slidably connected to the inner surface of the sliding groove 12. The locking block 13 is in the shape of a right trapezoid. Due to its right trapezoidal shape, during installation, the top plate 10 can be directly rotated to compress the right trapezoidal shape and make it retract into the sliding groove 12 without pulling the pull rod 14. The slide 12 is inserted into the slot. This structure reduces the number of operation steps and improves maintenance efficiency. The rear end of the locking block 13 is fixedly connected to the pull rod 14. The inside of the fixing block 11 is slidably connected to the pull rod 14. The outer surface of the pull rod 14 is provided with a spring 15. The front end of the spring 15 is fixedly connected to the locking block 13. The rear end of the spring 15 is fixedly connected to the bottom of the slide 12. The rear end of the pull rod 14 is fixedly connected to the lever 16. The front surface of the lever 16 is in contact with the fixing block 11. The top plate 10 is provided with a slot 17. The inner surface of the slot 17 is adapted to the locking block 13. There are two slots 17, which are distributed from left to right.

[0026] Working principle: During installation, rotate the top plate 10 so that it no longer obstructs the slot 2. Align the insert block 3 with the slot 2 and insert it. After insertion, rotate the top plate 10. The end of the top plate 10 presses against the inclined surface of the locking block 13, causing it to retract into the slide groove 12. At the same time, the spring 15 is compressed. When the top plate 10 rotates to fit against the upper surface of the outer frame 1, the slot 17 aligns with the locking block 13. At this time, the locking block 13 is no longer restricted by the compression of the top plate 10. The spring 15 causes the locking block 13 to spring back, allowing the locking block 13 to engage inside the slot 17. At this time, the top plate 10 is restricted by the lower surface of the locking block 13 and cannot rotate, thus completing the installation. When disassembly is required, simply pull the lever 14. The lever 14 drives the locking block 13 to slide and retract into the slot 17. At this time, the top plate 10 is no longer restricted by the locking block 13 and can be rotated, so that the insert block 3 and the grid body 4 are no longer restricted by the top plate 10. The grid body 4 can then be disassembled, cleaned, or replaced. This method of disassembly and installation is simple and effectively improves the efficiency of workers in maintaining the grid body 4.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
