Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a modular double-sided protective net for cooling towers. Background Technology

[0002] As the core equipment of industrial cooling systems, cooling towers need to have their air inlets protected by nets to prevent debris such as leaves, plastic bags, and dust from entering, thus avoiding blockage or damage to internal components and ensuring heat dissipation efficiency and stable operation of the equipment.

[0003] Existing cooling tower protective nets often have significant drawbacks: some protective nets use an integral structure or are assembled by on-site welding, resulting in complex and inefficient installation processes, and require complete disassembly for maintenance, making the operation cumbersome; some modular protective nets have imperfect designs, making it inconvenient to disassemble and assemble individual modules, and the connection between the protective net and the frame is not reliable enough, making them prone to loosening and falling off after long-term use; at the same time, traditional protective nets are mostly single-sided filter structures, with limited protective effects, or their unreasonable structural design affects air intake efficiency, making it difficult to balance protective performance and heat dissipation requirements.

[0004] To address this, a modular double-sided protective net for cooling towers is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems by proposing a cooling tower protection net structure that is easy to assemble, efficient to maintain, reliable in protection, and highly versatile.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular double-sided protective net for cooling towers, comprising a cooling tower body, wherein a rectangular frame is detachably fixed to the edge of the air inlet side of the cooling tower body by bolts, and at least two connecting vertical strips are evenly distributed and welded to the inner side of the rectangular frame along the vertical direction. Bending frame strips are fixed to the through holes at both ends of the rectangular frame surface along the length direction by bolts. At least one U-shaped bending clamping frame is fixed to the rectangular frame surface between two bending frame strips by bolts passing through the through holes. A protective net module body is movably inserted between the bending frame strips and adjacent U-shaped bending clamping frames, and between two adjacent U-shaped bending clamping frames. The protective net module body forms a detachable snap-fit ​​connection with the bending frame strips and the U-shaped bending clamping frames.

[0007] Preferably, the bolt front end near the center of the U-shaped bending clamping frame is fixed in the threaded through hole corresponding to the connecting vertical bar, realizing the double fixation of the U-shaped bending clamping frame; trapezoidal through holes are neatly and evenly distributed on the inner surfaces of the bending frame and the U-shaped bending clamping frame, wherein a row of trapezoidal through holes is formed along the length direction on the bending frame, and a row of trapezoidal through holes is formed along the length direction on the upper and lower edges of the surface of the U-shaped bending clamping frame, and both ends of the inner wall of the trapezoidal through holes are set as guide slopes.

[0008] Preferably, the main body of the protective net module includes a rectangular outer frame that is adapted to be inserted between the bent frame strip and the U-shaped bent clamping frame, or between the U-shaped bent clamping frames; two rectangular filter sheets that are welded to the front and rear surface edges inside each rectangular outer frame; multiple limiting blocks that are movably inserted into the rectangular through holes at both ends of the left and right sides of each rectangular outer frame; and telescopic springs that are welded to the back ends of each limiting block; the two rectangular filter sheets are arranged in parallel.

[0009] Preferably, the rear end of the telescopic spring is welded and fixed to the inner side wall of the rectangular outer frame, and the front end of the limiting block is configured as a trapezoidal structure adapted to the trapezoidal through hole.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] See Figure 1-9 As shown, the main body 1 of the cooling tower serves as the installation foundation and application carrier for the protective net. Its air inlet surface provides an installation reference surface for the entire modular protective net, ensuring that the protective net can accurately correspond to the air inlet position, effectively protecting the air inlet channel, and providing structural support for the normal ventilation and heat dissipation of the cooling tower.

[0015] The rectangular frame 2 serves as the overall framework of the protective netting. It is detachably and fixedly assembled to the edge of the air inlet side of the cooling tower body 1 using bolts, playing a core role in connecting and fixing various components. Its rectangular structure adapts to the shape of the cooling tower air inlet, providing an installation carrier for connecting the vertical strips 3, the bent frame strips 4, and the U-shaped bent clamping frame 5, ensuring the structural stability and integrity of the entire protective netting.

[0016] The connecting vertical bars 3 are welded to the inside of the rectangular frame 2 and evenly distributed along the vertical direction. On the one hand, this enhances the overall rigidity of the rectangular frame 2 and prevents the frame from deforming under stress. On the other hand, it provides additional fixing points for the U-shaped bending clamping frame 5. The middle part of the U-shaped bending clamping frame 5 is fixed to the threaded through hole of the connecting vertical bar 3 by bolts, realizing the double fixing of the U-shaped bending clamping frame 5, improving the installation firmness of the clamping frame, and preventing the protective net module body 6 from loosening after assembly.

[0017] The bent frame strip 4 is fixed to both ends of the rectangular frame 2 along its length by bolts, serving as the end limiting structure of the protective net module body 6. A row of trapezoidal through holes on its inner surface is adapted to the limiting block 603 of the protective net module body 6, realizing the snap-fit ​​positioning of the end protective net module body 6; at the same time, the guide slope of the inner wall of the trapezoidal through hole provides a guiding function for the insertion and removal of the limiting block 603, facilitating the quick assembly and disassembly of the protective net module body 6.

[0018] The U-shaped bending clamping frame 5 is fixedly assembled between two bent frame strips 4, serving to separate and clamp the main body 6 of the protective net module, dividing the entire protective net area into multiple independent modular installation units, facilitating the replacement and maintenance of individual protective net module main bodies 6. The trapezoidal through holes on its two side walls correspond to the trapezoidal through holes on the bent frame strips 4, jointly achieving bidirectional snap-fit ​​positioning of adjacent protective net module main bodies 6; simultaneously, it is fixed to the connecting vertical strip 3 with bolts, forming a double fixing structure to ensure that the U-shaped bending clamping frame 5 does not shift during long-term use.

[0019] The main body 6 of the protective net module, as the core functional unit of the protective net, is movably inserted between the bent edge strip 4 and the U-shaped bent clamping frame 5, or between adjacent U-shaped bent clamping frames 5. It achieves quick assembly and disassembly through a detachable snap-fit ​​connection. The specific functions of its components are as follows: The rectangular outer frame 601 serves as the supporting skeleton of the main body 6 of the protective net module. It is adapted to be inserted between various clamping structures, providing an installation carrier for the rectangular filter screen 602, the limiting block 603 and the telescopic spring 604, while ensuring the overall structural strength of the module and preventing the rectangular filter screen 602 from deforming under stress.

[0020] The rectangular filter mesh 602 is welded to the front and rear edges of the inner surface of the rectangular outer frame 601 to form a double-sided protective structure. This structure can effectively block external debris (such as leaves, plastic bags, dust, etc.) from entering the cooling tower body 1, preventing blockage or damage to the internal components of the cooling tower. At the same time, the two meshes are arranged in parallel, ensuring the protective effect without affecting the air intake efficiency of the cooling tower and ensuring stable heat dissipation performance.

[0021] The limiting block 603 is movably inserted into the through holes on the left and right sides of the rectangular outer frame 601. Its front end is set as a trapezoidal structure that matches the trapezoidal through hole. Under the elastic force of the telescopic spring 604, it is inserted into the trapezoidal through hole of the bent frame strip 4 or the U-shaped bent clamping frame 5 to achieve the positioning and fixation of the main body 6 of the protective net module and prevent the module from falling off during use. When disassembling, the trapezoidal structure, together with the guide slope of the through hole, can press the limiting block 603 into the rectangular outer frame 601 with external force to achieve quick disassembly.

[0022] The telescopic spring 604 is welded between the two ends of the back of the limiting block 603 and the inner sidewall of the rectangular outer frame 601, providing a continuous elastic force for the limiting block 603 and ensuring that the front end of the limiting block 603 is stably engaged in the trapezoidal through hole. When the main body 6 of the protective net module is disassembled, the telescopic spring 604 can be compressed, causing the limiting block 603 to retract into the rectangular outer frame 601. After disassembly, it can automatically reset, ensuring the reliability of repeated assembly of the module.

[0023] The operation process of this utility model is as follows: When installing the protective net, select a rectangular frame 2 of the corresponding specification according to the actual size of the air inlet of the cooling tower body 1, attach the rectangular frame 2 to the edge of the air inlet surface of the cooling tower body 1, align the frame with the through hole position on the cooling tower body, and insert bolts into the through holes in sequence and tighten them to complete the detachable and fixed assembly of the rectangular frame 2. Inside the rectangular frame 2, at least two connecting vertical strips 3 are welded evenly in the vertical direction to ensure that the connecting vertical strips 3 are firmly welded to the rectangular frame 2, forming a frame reinforcement structure. Take two bent frame strips 4, align them with the through holes at both ends of the rectangular frame 2 along its length, insert bolts into the through holes and tighten them to achieve a fixed assembly of the bent frame strips 4 and the rectangular frame 2, ensuring that the inner surface of the bent frame strips 4 (the side with the trapezoidal through hole) faces the inside of the frame. According to the modular division requirements of the protective net, select an appropriate number of U-shaped bending clamping frames 5 and place them on the surface of the rectangular frame 2 between two bending frame strips 4. Align the through holes on the U-shaped bending clamping frames 5 with the corresponding through holes on the rectangular frame 2, and first insert bolts for initial fixation. Then, pass the bolts through the through holes near the middle of the U-shaped bending clamping frames 5 and screw them into the threaded through holes corresponding to the connecting vertical strips 3 to complete the double fixation of the U-shaped bending clamping frames 5, so that each U-shaped bending clamping frame 5 is evenly distributed between the two bending frame strips 4.

[0024] Align the bent frame strip 4 with the installation gap between it and the adjacent U-shaped bent clamping frame 5, or between two adjacent U-shaped bent clamping frames 5, and smoothly insert it horizontally. During insertion, the trapezoidal structure at the front end of the limiting block 603 is squeezed by the inner wall of the installation gap, compressing the telescopic spring 604 and retracting into the rectangular outer frame 601; when the main body 6 of the protective net module is inserted to the preset position, the limiting block 603 pops out under the elastic force of the telescopic spring 604 and locks into the trapezoidal through hole corresponding to the bent frame strip 4 or the U-shaped bent clamping frame 5, thereby achieving module positioning and fixation. Repeat the previous step, continuously inserting the protective net module body 6 until all installation gaps are filled and the protective net module body 6 completely covers the air inlet of the cooling tower body 1. The installation operation is then complete.

[0025] When disassembling the protective net, determine the position of the main body 6 of the protective net module to be disassembled, and directly push the main body 6 of the protective net module. The trapezoidal structure at the front end of the limiting block 603 slides along the guide slope of the trapezoidal through hole, compresses the telescopic spring 604 and retracts it into the rectangular outer frame 601, releases the module from the snap-fit ​​positioning of the bent side strip 4 and the U-shaped bent clamping frame 5, and smoothly pulls out the main body 6 of the protective net module in the horizontal direction to complete the disassembly of a single module.

[0026] If multiple adjacent protective netting module bodies 6 need to be disassembled, repeat the above steps and pull out the target protective netting module body 6 in sequence; if the interior of the cooling tower needs to be repaired, the protective netting module body 6 in the corresponding position and direction of removal can be disassembled according to the maintenance operation space requirements, leaving an operation channel.

[0027] The removed protective net module body 6 has its limiting block 603 automatically reset under the elastic force of the telescopic spring 604, which facilitates the subsequent repeated assembly of the protective net module body 6.

[0028] Although embodiments of the present invention have been shown and described, those skilled in the art should understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of protection of the present invention is defined by the appended claims and their equivalents.
