[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The cooling tower cleaning extension rod of this application embodiment can be used for cleaning cooling towers during aluminum processing. By connecting a high-pressure water pipe through the connector, it can wash away powder particles adhering to the surface of the cooling tower. The technical solution of this application will be described below with reference to specific embodiments.

[0022] like Figure 1 The figure shows a schematic diagram of the cooling tower cleaning extension rod according to Embodiment 1 of this application. As shown, the cooling tower cleaning extension rod in this embodiment includes:

[0023] The joint part 1, the connecting pipe 3 and the spray head 4; wherein the joint part 1 comprises a connecting body 2, a water inlet joint 5 and a water outlet joint 6, wherein the water inlet joint 5 is arranged on one side of the connecting body 2, and the water outlet joint 6 is arranged on the other side of the connecting body 2. The cooling tower cleaning extension rod in the embodiment is connected with a high-pressure water pipe, and the high-pressure resistance and sealing performance of the cooling tower cleaning extension rod are required to be high, therefore, the joint part can be integrally formed by casting, or the connecting body 2 can be connected with the water inlet joint 5 by welding or threaded connection, or the connecting body 2 can be connected with the water outlet joint 6 by welding or threaded connection. The embodiment is only exemplary to describe the forming mode of the connecting part 1, and is not intended to limit the forming mode of the connecting part 1. In addition, since the joint part 1 is long-term connected with high-pressure water, an oxidation-resistant material (such as copper or other alloy material) can be used, or a plating layer can be formed on the outer surface or inner lining of the joint part 1 to improve the oxidation resistance and prevent rust from blocking.

[0024] One end of the connecting pipe 3 is connected with the water outlet joint 6, and the other end of the connecting pipe 3 is provided with a bending part and connected with the water inlet of the spray head 4 through the bending part. The connecting pipe 3 is a hollow tubular structure, the connecting pipe 3 has a cylindrical inner cavity, the axis of the inner cavity of the connecting pipe is a straight line, and in order to ensure the high-pressure resistance and erosion resistance of the connecting pipe 3, the inner wall of the connecting pipe 3 has a certain thickness, for example, 1mm-2mm, and the inner wall of the connecting pipe is smooth to avoid the abrasion of the connecting pipe caused by the erosion of high-pressure water to the inner wall, thereby improving the durability.

[0025] In order to improve the overall high-pressure resistance of the device, the connecting pipe 3 can be welded, threaded or integrally formed with the water outlet joint 6. In order to increase the flow rate of the water sprayed by the spray head 4 and enhance the cleaning effect, the inner diameter of the connecting pipe 3 can be smaller than the inner diameter of the water outlet joint 6. And the connecting part of the connecting pipe 3 and the water outlet joint 6 can be in a trumpet shape, that is, the inner diameter gradually decreases, and finally the inner diameter of the other part of the connecting pipe 3 is the same, which can avoid the change of the water flow rate caused by the too large pressure change, and cause the damage to the connecting pipe 3.

[0026] At the same time, the connection mode of the bending part of the connecting pipe 3 and the spray head 4 can also refer to the connection mode of the connecting pipe 3 and the water outlet joint 6, which will not be repeated here.

[0027] The spray head 4 in the embodiment can be in a cylindrical shape as a whole, and has two end faces, one of which is provided with a water inlet for connecting with the connecting pipe 3, and the other is provided with a water outlet through which the water is sprayed along the axial direction of the spray head 4 or is inclined outward along the axial direction of the spray head 4.

[0028] The cooling tower cleaning extension rod of the embodiment of the present application is provided with a connecting pipe between the joint part and the spray head, which extends the extension distance of the spray head, and the spray head is connected with the curved part of the connecting pipe, which can clean the cooling tower at an angle perpendicular to the surface of the tower body or at an angle approximately perpendicular to the tower body, which can extend to a higher height and effectively flush the attachments on the surface of the tower body.

[0029] As an optional embodiment of the present application, in the above embodiment, the joint part has a hollow cavity, and the inner diameter of the hollow cavity is larger than the inner diameter of the connecting pipe. Since the cooling tower cleaning extension rod of the embodiment of the present application is used for high-pressure water, in order to avoid the abrasion of the connecting part of the connecting pipe caused by the flushing of the substances carried in the high-pressure water at high flow rate, the inside of the joint part is provided as a hollow cavity to buffer the high-speed water flow. In order to further improve the buffering effect of the high-speed water flow, the axis of the water inlet joint and the axis of the water outlet joint are not collinear. Since the water inlet joint and the water outlet joint are both communicated with the joint part (i.e. the hollow cavity of the joint part), if the axes of the water inlet joint and the water outlet joint are collinear, the water entering the joint part through the water inlet joint may not stay in the joint part, but directly flow out of the cavity of the water outlet joint, which cannot buffer the small particles carried in the water, thereby causing the abrasion of the water joint.

[0030] As an optional embodiment of the present application, in the above embodiment, the inner diameter of the water inlet joint is larger than the inner diameter of the connecting pipe, so that the water pressure gradually increases from the water supply end to the spray head, which can increase the pressure of the outlet water and avoid the formation of an air space inside the whole device, which affects the continuity of the outlet water.

[0031] Similarly, the inner diameter of the water inlet joint can be set to be larger than the inner diameter of the connecting pipe, which can further enhance the above technical effect.

[0032] As shown in Figure 2 Fig. 2 is a structure schematic diagram of the cooling tower cleaning extension rod of the second embodiment of the present application. As shown in the figure, the cooling tower cleaning extension rod of the embodiment of the present application comprises:

[0033] a joint part 1, a connecting pipe 3 and a spray head 4; wherein the joint part 1 comprises a connecting body 2, a water inlet joint 5 and a water outlet joint 6, wherein the water inlet joint 5 is arranged on one side of the connecting body 2, and the water outlet joint 6 is arranged on the other side of the connecting body 2. Different from the above embodiment, the water inlet joint 5 in the present embodiment is provided with two, one of which can be connected with a high-pressure water supply hose, and the other of which can be connected with a high-pressure water supply hard pipe, or both of which can be connected with a high-pressure water supply hard pipe, so as to support the cooling tower cleaning extension rod, thereby controlling the movement of the spray head of the cooling tower cleaning extension rod to complete the cleaning of the surface of the cooling tower tower body. Specifically, as shown in Figure 3Fig. 2 is a schematic diagram of the water flow direction in the joint part of the cooling tower cleaning extension rod in Embodiment Two of the present application. Figure 3 As can be seen from Fig. 2, one side of the connecting body 2 of the joint part 1 is provided with two water inlet joints 5, and the water flows through the water inlet joints 5 converge in the middle of the connecting body 2 and flow out through the water outlet joint 6 provided at the converging position. The water flowing into the connecting body 2 through the water inlet joints 5 respectively can come from different water supply devices (such as high-pressure water pumps), so that the water pressure can be increased by converging in the connecting body 2, so that the flow rate of the water flow sprayed through the spray head 4 is faster, and the scouring ability of the water flow is enhanced. At the same time, in the present embodiment, the water flows through the water inlet joints 5 converge in the middle of the connecting body 2, which can also buffer the speed of the fine particles carried in the water, avoiding the abrasion of the connecting body 2 and the subsequent connecting pipe 3.

[0034] In order to prevent the pipeline from being blocked, a filter screen can also be provided inside the connecting body 2, which can filter the water flow and also slow down the speed of the fine particles in the water flow, thereby buffering the speed of the fine particles.

[0035] It is not difficult to think that three or more water inlet joints 5 can be connected to the connecting body 2, and the present embodiment will not be described one by one.

[0036] The cooling tower cleaning extension rod of the present embodiment can increase the water pressure by providing two water inlet joints and converging in the connecting body, thereby enhancing the cleaning effect, and also buffering the speed of the fine particles carried in the water, thereby reducing the abrasion of the equipment.

[0037] In addition, as an optional embodiment of the present application, in the above embodiment, the spray head is a ceramic spray head, which can improve the high-pressure resistance and wear resistance of the spray head, thereby enhancing the durability of the device as a whole.

[0038] In some embodiments of the present application, the spray head is a cylindrical structure, and a spray opening is provided at the end of the spray head away from the connecting pipe. Of course, in some other embodiments, the spray head can also have other shapes.

[0039] The preferred embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the specific details in the above embodiments. Within the technical concept of the present application, the technical solution of the present application can be subjected to various simple modifications, and these simple modifications all belong to the protection scope of the present application.

[0040] In addition, it should be noted that the various specific technical features described in the foregoing detailed description can be combined in any suitable manner in the specific embodiments, without departing from the scope of the application. To avoid unnecessary repetition, the application will not describe each possible combination of the various features. In general, the various embodiments of the application can include a variety of combinations and / or sub-combinations of the various features described in the detailed description above.

[0041] Furthermore, the various embodiments of the application can also be combined in any suitable manner, as long as they do not contradict the idea of the application. They should therefore also be considered as disclosed by the application.
