Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, and in particular to a cooling tower protective device. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the flow of water and air to exchange heat to produce steam, and the steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. In order to ensure the normal operation of the system, the cooling tower will inevitably be hit by the outside world during its use, and its internal structure will inevitably be damaged after the collision, which requires the use of a cooling tower protective device.

[0003] Patent document CN219829627U discloses a cooling tower protection device, "including a cooling tower air inlet, wherein a U-shaped frame track is fixedly connected to the air outlet of the cooling tower air inlet, a slider is slidably connected to the inner side of the U-shaped frame track, a window frame is fixedly connected to the top of the slider, a gauze is arranged on the inner side of the window frame, a cross bar is fixedly connected between the inner side of the cooling tower air inlet and the U-shaped frame track, and a wind pressure sensor is arranged on the side of the cross bar. The utility model can optimize and improve the cooling tower air inlet by providing a U-shaped frame track, a window frame and a gauze, and can protect the cooling tower filler, ensure the heat exchange efficiency of the cooling tower and extend the service life of the cooling tower filler."

[0004] The above-mentioned equipment can optimize and improve the air inlet of the cooling tower by being provided with a U-shaped frame track, window frame and mesh, and can protect the cooling tower filler, ensure the heat exchange efficiency of the cooling tower and extend the service life of the cooling tower filler. However, when the equipment is hit, it is difficult for the protective structure on its surface to offset the force caused by the impact through a small movement, so that the protective structure bears all the impact force. Over time, the protective structure will inevitably be damaged as the number of collisions increases, and replacing it will inevitably increase the cost of using the equipment, which requires staff to improve their equipment. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the situation in which a cooling tower protective device in the prior art is difficult to offset part of the impact force, resulting in the protective structure being easily damaged after long-term use, thereby providing a cooling tower protective device.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] include:

[0008] A tower body, wherein fixed blocks are arranged on both sides of the tower body, one side of the inner wall of the fixed block is rotatably connected to a first connecting block, one side of the first connecting block is rotatably connected to a telescopic rod, one end of the telescopic rod is rotatably connected to a second connecting block, the surface of the second connecting block is rotatably connected to an installation frame, a protective net is arranged on the inner wall of the installation frame, and a first spring is arranged on the inner wall of the telescopic rod.

[0009] As an optional technical solution, a fixed frame is provided on the surface of the tower body, and a protective roller is rotatably connected to the inner wall of the fixed frame.

[0010] As an optional technical solution, card slots are opened on both sides of the top of the fixed frame, and connecting card blocks are inserted into the inner walls of the card slots. Limit blocks are set on both sides of the fixed frame, and one side of the connecting card block is slidably connected to the inner wall of the limit block.

[0011] As an optional technical solution, a fixing plate is provided on the top of the connection block, a slot is provided on one side of the connection block, and one side of the fixing plate is overlapped with one side of the tower body.

[0012] As an optional technical solution, a plug is slidably connected to the inner wall of the fixing frame, and a rubber pad is provided on the surface of the protective roller.

[0013] As an optional technical solution, a second spring is provided on the surface of the plug, and a handle is provided on one side of the plug.

[0014] As an optional technical solution, an input pipe is provided on the top of the tower body, a discharge pipe is provided on the bottom of one side of the tower body, and a hand wheel is rotatably connected to the surface of the discharge pipe.

[0015] The utility model technical solution has the following advantages:

[0016] 1. The utility model uses the telescopic rod to pull the installation frame around. When the two sides of the tower body are collided with small objects, the collision objects first contact the protective net and are captured by the protective net, so that they stay on the surface of the protective net, thereby preventing the collision objects from causing damage to the tower body. When some larger objects collide with the two sides of the tower body, the objects contact the installation frame, thereby concentrating the force on the surface of the installation frame. When the installation frame is moved toward the tower body by the force, the spring in the telescopic rod pulls the installation frame to reset slightly through elastic force, thereby offsetting part of the force and preventing the protective structure from bearing all the force, thereby increasing the service life of the equipment. The telescopic rod has a limited range of motion. After the telescopic rod is rotated to the maximum angle, the installation frame is pulled to avoid collision between the installation frame and the tower body, thereby avoiding damage to the tower body.

[0017] 2. The utility model uses protective rollers that roll on both sides of the tower body. Before the collision object contacts the tower body, it first contacts the protective rollers on both sides of the tower body. When the protective rollers are collided, they are affected by the force and roll to one side of the tower body. The protective rollers drive the collision object on the surface to move slightly by rolling, so that the trajectory of the collision object is offset, thereby moving in the rolling direction of the protective rollers, and taking it away from the surface of the tower body, thereby avoiding the tower body from being hit.

When the mounting frame 6 is subjected to the force and moves toward the tower body 1, the first spring 8 in the telescopic rod 4 pulls the mounting frame 6 in the opposite direction of the force through elastic force to perform a small reset, thereby offsetting a part of the force received by the collision, and the movable range of the telescopic rod 4 is limited. After the telescopic rod 4 rotates to the maximum angle, the mounting frame 6 is pulled, thereby preventing the mounting frame 6 from colliding with the tower body 1.

[0035] The material is injected into the tower body 1 through the input pipe 19. When the two sides of the tower body 1 are collided with by small objects, the collision objects first contact the protective net 7, and are captured by the protective net 7, so that they stay on the surface of the protective net 7, and then fall from the surface of the protective net 7 by the gravity of the collision objects themselves, thereby preventing the collision objects from causing damage to the tower body 1. When some larger objects collide with the two sides of the tower body 1, the objects contact the surfaces of the installation frame 6 and the protective net 7, thereby concentrating the force on the surfaces of the installation frame 6 and the protective net 7.
