Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooling towers, in particular to a square counter-current closed cooling tower. Background Art
[0002] A closed cooling tower (also called an evaporative air cooler, sealed cooling tower, or enclosed cooling tower) incorporates a tubular heat exchanger within the tower. The cooling effect is achieved through heat exchange between circulating air, spray water outside the tubes, and circulating water within the tubes. Because the circulating water circulates within the tubes in a closed loop, it ensures water quality is uncontaminated, effectively protecting the efficient operation of the main equipment and extending its service life. When the outside temperature is low, the spray water system can be shut down to conserve water.
[0003] The installation of a traditional square counterflow closed cooling tower typically requires digging a foundation pit, placing the cooling tower body directly into the pit, and securing it through welding, bolting, and other methods. This method is not only cumbersome to install but also places high demands on the foundation. If the foundation is uneven or loose, it can easily cause the cooling tower to wobble during operation, affecting heat exchange efficiency and even causing safety accidents. This is why the square counterflow closed cooling tower is so popular. Utility Model Content
[0004] The purpose of the utility model is to provide a square counterflow closed cooling tower, which solves the problem that the installation of traditional square counterflow closed cooling towers in the prior art usually requires first digging a foundation pit in the ground, then directly placing the cooling tower body in the pit, and then fixing it by welding, bolting, etc. This method is not only cumbersome to install, but also has high requirements for the foundation. If the foundation is uneven or loose, it is very easy to cause the cooling tower to shake during operation, affecting the heat exchange efficiency and even causing safety accidents.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] The top of the bottom frame is provided with a cooling tower body, and both sides of the bottom of the cooling tower body are fixedly connected with limit blocks adapted for the inner cavity of the bottom frame, and both sides of the outer wall of one side of the limit block are provided with insertion holes, and an inner frame is horizontally provided in the middle of the inner cavity of the bottom frame, and a two-way screw rod is horizontally provided in the inner cavity of the inner frame, and screw sleeves are sleeved on both sides of the outer ring of the two-way screw rod, and cross bars are fixedly connected on both sides of the outer ring of the screw sleeve, and an insertion rod is fixedly connected on one side of the cross bar, one end of the insertion rod passes through the adjacent inner frame side wall and is plugged into the corresponding insertion hole, and a bevel gear 1 is sleeved on the middle part of the outer ring of the two-way screw rod, and a bevel gear 2 is provided on one side of the bevel gear 1, and one end of the bevel gear 2 is fixedly connected to a round rod, and one end of the round rod passes through the adjacent inner frame side wall and the bottom frame side wall in sequence and extends to one side of the bottom frame.
[0007] Preferably, the extended end of the round rod is fixedly connected to a handle.
[0008] Preferably, both ends of the bidirectional screw rod are rotatably connected to the inner walls of the adjacent inner frames via a rotating shaft.
[0009] Preferably, the outer ring of the bevel gear 1 and the outer ring of the bevel gear 2 are connected by meshing with teeth.
[0010] Preferably, the two screw sleeves are symmetrically distributed on both sides of the outer ring of the bidirectional screw rod.

This design fully considers the ease of use and physical burden of the installer. The entire installation process can be completed with a simple twist of the handle, eliminating the need for large tools or intensive manual labor, significantly reducing the workload and risk of injury for the installer.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0024] Reference Figure 1-5 , a square countercurrent closed cooling tower comprises a bottom frame 2, a cooling tower body 1 is provided on the top of the bottom frame 2, and both sides of the bottom of the cooling tower body 1 are fixedly connected with a limit block 3 adapted to the inner cavity of the bottom frame 2, and a socket 5 is opened on both sides of the outer wall of one side of the limit block 3. An inner frame 4 is horizontally provided in the middle of the inner cavity of the bottom frame 2, and a two-way screw rod 7 is horizontally provided in the inner cavity of the inner frame 4. Both sides of the outer ring of the two-way screw rod 7 are sleeved with screw sleeves 8, and both sides of the outer ring of the screw sleeve 8 are fixedly connected with a cross bar 9, and one side of the cross bar 9 is fixedly connected with a plug rod 10, one end of the plug rod 10 passes through the adjacent side wall of the inner frame 4 and is plugged into the corresponding socket 5, and the middle part of the outer ring of the two-way screw rod 7 is sleeved with a bevel gear 11, and a bevel gear 2 12 is provided on one side of the bevel gear 11. One end of the bevel gear 2 12 is fixedly connected with a round rod 6, and one end of the round rod 6 sequentially passes through the adjacent side wall of the inner frame 4 and the side wall of the bottom frame 2 and extends to one side of the bottom frame 2.
[0025] This program has the following working process:
[0026] When personnel are in use, they first connect the bottom frame 2 with the pre-dug foundation pit. After the position of the bottom frame 2 is stable, the personnel clamp the limit blocks 3 on both sides of the bottom of the cooling tower body 1 with the inner cavity of the bottom frame 2. Then the personnel rotate the handle to make the handle drive the round rod 6 to rotate, and the bevel gear 2 12 is driven to drive the bevel gear 1 11 to rotate. The bidirectional screw rod 7 rotates at the same time, and the two screw sleeves 8 respectively drive the corresponding cross bar 9 and the insertion rod 10 to move, so that the insertion rod 10 is respectively plugged into the inner cavity of the adjacent corresponding socket 5, thereby locking the limit block 3. Conversely, when the personnel need to release the lock on the bottom of the cooling tower body 1, they can rotate the round rod 6 in the opposite direction.
[0027] According to the above working process, we can know that:
[0028] Through the structural design, personnel can quickly install the limiting operation on the cooling tower body 1 before use, and the bottom of the cooling tower body 1 after installation can always be in a stable locked state, which reduces the installation burden of the cooling tower body 1 for personnel, improves the work efficiency of personnel, and ensures the stability of the bottom of the cooling tower body 1 during operation.
[0029] Furthermore, a handle is fixedly connected to the extended end of the round rod 6. Specifically, by fixing the handle to the round rod 6, during the work process, the operator can directly rotate the handle to drive the round rod 6 to rotate without using other tools, thereby simplifying the operation process. This design facilitates the operation of the operator and improves the installation efficiency.
[0030] Furthermore, both ends of the bidirectional screw rod 7 are rotatably connected to the inner wall of the adjacent inner frame 4 via a rotating shaft. Specifically, the connection between the rotating shaft and the inner wall of the inner frame 4 allows the bidirectional screw rod 7 to stably rotate within the inner frame 4 when driven by the bevel gear 11. This design ensures the rotational stability of the bidirectional screw rod 7, thereby ensuring the accurate displacement of the insertion rod 10.
[0031] Furthermore, the outer rings of bevel gear 11 and bevel gear 2 12 are connected by meshing teeth. Specifically, through the meshing arrangement of bevel gear 11 and bevel gear 2 12, when round rod 6 rotates, it can drive bevel gear 2 12 to rotate, and in turn, through the meshing action, it can drive bevel gear 11 and the bidirectional screw 7 connected thereto to rotate. This design achieves accurate and efficient power transmission, ensuring that the insertion rod 10 can be smoothly inserted into the socket 5.
[0032] Furthermore, two threaded sleeves 8 are symmetrically arranged on either side of the outer ring of the bidirectional screw 7. Specifically, due to the symmetrical arrangement of the threaded sleeves 8, when the bidirectional screw 7 rotates, the two threaded sleeves 8 can simultaneously and symmetrically move in opposite directions, respectively driving the crossbar 9 and the insertion rod 10 to insert into the corresponding insertion hole 5. This design not only ensures the synchronization and stability of the insertion of the insertion rod 10, but also enhances the connection strength between the cooling tower body 1 and the base frame 2.
[0033] Furthermore, one side of the stopper 3 abuts against the inner wall of the adjacent base frame 2. Specifically, by abutting the inner wall of the base frame 2, the stopper 3 can first contact the base frame 2 and perform a preliminary positioning function when the cooling tower body 1 is placed on the base frame 2. This design improves the accuracy of the installation of the cooling tower body 1, provides a good foundation for the subsequent insertion of the rod 10, and further ensures the stability of the cooling tower body 1.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention.
