Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower cleaning and discloses a cooling tower scale cleaning 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. This is an evaporative heat dissipation device to ensure the normal operation of the system. The device is generally barrel-shaped. After the cooling tower has been used for a period of time, scale will form on the inner wall, which usually needs to be cleaned by a cleaning device.

[0003] The patent number CN218743752U in the prior art introduces a cooling tower cleaning device, including a cooling tower body and a cleaning component, wherein a rotating shaft is arranged inside the cooling tower body, and a mounting ring is fixed on the periphery of the rotating shaft, and a limit frame is installed at both ends of the mounting ring, and a placement slot is provided inside the limit frame, and the cleaning component is installed inside the placement slot, and limit blocks are arranged at both ends of the front and rear sides of the fixed frame, and a cleaning brush is installed on the outside of the mounting seat, and a tightening screw is installed at the front end of the limit frame. In the cooling tower cleaning device, the cover shell is connected and installed with the cooling tower body through a buckle, and the installation method is simple and convenient, and it is easy to disassemble and assemble. The scale on the inner wall and the bottom surface of the cooling tower body can be cleaned by the cleaning brush. At the same time, when the cleaning brush on one side is worn out, the operator can pull out the fixed frame, flip it left and right to change the top to the bottom, and then insert the limit frame to use the cleaning brush on the other side, thereby reducing the number of major maintenance of the device.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] (1) The patents in the prior art cannot adjust the width when in use, and some cooling towers with larger diameters cannot be cleaned.

[0006] (2) The patents in the prior art cannot adjust the height when in use. Some cooling towers are too high to be fully cleaned, and the bottom of the cooling tower cannot be cleaned. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a cooling tower scale cleaning device which can not only adjust the width but also is suitable for cooling towers of different heights.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions: a cooling tower scale cleaning device, comprising a mounting plate, a column is provided at the bottom end of the mounting plate, a sliding rod is slidably connected inside the column, a rotating block is rotatably connected at the bottom end of the sliding rod, a second motor is provided inside the bottom end of the sliding rod, the bottom end of the second motor is fixedly connected to the rotating block, a vertical rod is provided at the bottom end of the rotating block, a cleaning bottom plate is provided at the bottom end of the vertical rod, cross arms are provided at both left and right ends of the rotating block, a telescopic rod is slidably connected inside the cross arms, cleaning plates are provided at one end of the two telescopic rods away from each other, bristles are provided on the surfaces of the two cleaning plates away from each other, and adjustment devices are provided at one end of the two cross arms away from each other.

[0009] Furthermore, a screw rod is rotatably connected inside the column, the upper end of the screw rod is connected to a first motor, and the bottom end of the first motor is fixedly connected to a mounting plate.

[0012] Furthermore, a rotating rod is slidably connected inside the moving column, and a spring is provided at one end of the rotating rod, and the spring is located inside the moving column.

[0013] Furthermore, the movable column and the rotating rod are both rotatably connected to the cross arm, a first gear is provided at one end of the rotating rod, a rack is provided on the upper end surface of the telescopic rod, and the first gear meshes with the rack.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:
