DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will make a detailed description of the two implementation modes of the present application with reference to the accompanying drawings.

[0022] The first implementation mode:

[0023] Figures 1-5Disclosed is a convenient maintenance type low-temperature cooling circulation pump, including a chassis 1. A mounting seat 2 is fixedly connected to the side end of the chassis 1. The upper end of the mounting seat 2 is placed in contact with a circulation pump body 3. A plugging groove 4 is opened at the upper end of the mounting seat 2. A protective cover 5 is movably inserted into the inside of the plugging groove 4. A first moving plate 6 is hinged to each of the pair of side ends of the protective cover 5. A second moving plate 25 is hinged to the upper end of the protective cover 5. A third moving plate 7 is movably inserted into the end of the protective cover 5 away from the chassis 1. A plurality of wire arranging holes are opened at the end of the protective cover 5 close to the chassis 1. A pair of fixed tubes 8 are fixedly connected to the end of the protective cover 5 away from the chassis 1. A first compression spring 9 and a slider 10 are slidably sleeved on the outer end of the fixed tube 8. The end of the first compression spring 9 away from the slider 10 is fixedly connected to a limiting ring 11. The inner wall of the limiting ring 11 is fixedly connected to the outer end of the fixed tube 8. A tension spring 12 is fixedly connected to the inside of the fixed tube 8. The end of the tension spring 12 away from the fixed tube 8 is fixedly connected to a moving frame 13. A limiting tube 14 is fixedly connected to the end of the moving frame 13 close to the third moving plate 7. A pair of limiting grooves 15 into which the limiting tube 14 is movably inserted are opened at the outer end of the third moving plate 7. A plugging connecting tube 16 is fixedly connected to the end of the slider 10 away from the first compression spring 9. A circular groove 17 into which the plugging connecting tube 16 is movably inserted is opened at the end of the first moving plate 6 away from the chassis 1;

[0024] A pair of rectangular grooves 18 are opened at the upper end of the protective cover 5. A support tube 19 is fixedly connected to the inner wall of the rectangular groove 18. A second compression spring 20 and a socket block 21 are slidably sleeved on the outer end of the support tube 19. A pair of docking grooves 22 into which the socket block 21 is movably inserted are opened at the end of the second moving plate 25 away from the chassis 1. A vertical block 23 is fixedly connected to each of the pair of side ends of the third moving plate 7. A vertical groove 24 into which the vertical block 23 is movably inserted is opened on each of the pair of inner side walls of the protective cover 5. In the initial state, the end of the plugging connecting tube 16 away from the slider 10 penetrates through the protective cover 5 and is inserted into the circular groove 17. Handles are fixedly connected to the side ends of the first moving plate 6, the second moving plate 25 and the third moving plate 7. By using the handles, it is convenient for personnel to manually pull the first moving plate 6, the second moving plate 25 and the third moving plate 7. In the initial state, both the first compression spring 9 and the second compression spring 20 are in a contracted state. The outer diameter of the limiting ring 11 is greater than the outer diameter of the first compression spring 9.

[0025] When in use, place the circulation pump body 3 on the mounting seat 2, and then insert the lower end of the protective cover 5 into the plugging groove 4. Use the protective cover 5 to cover the circulation pump body 3 on the mounting seat 2 to protect it, isolate it from external forces, and reduce the degree of damage caused by direct external force acting on it. Finally, insert the pipelines of other devices into the protective cover 5 through the wire arranging holes and connect them to the circulation pump body 3;

[0026] When performing maintenance on the circulation pump body 3, it can be divided into the following steps:

[0027] Step 1: When overhauling a pair of side ends of the circulating pump body 3, keep the position 13 stationary. Pull the slider 10 towards the end away from the protective cover 5. At the same time, the side end of the slider 10 will continue to compress the first compression spring 9, causing the first compression spring 9 to continue to contract between the slider 10 and the limit ring 11. At the same time, the other side end of the slider 10 will drive the insertion pipe 16 to move together, so that one end of the insertion pipe 16 is removed from the circular groove 17 to release the limit of the insertion pipe 16 on the first moving plate 6. Then, turn the first moving plate 6 upwards (combined with Figure 2 as shown), expose a pair of side ends of the circulating pump body 3, and then overhaul its pair of side ends;

[0028] Step 2: When overhauling the upper end of the circulating pump body 3, it is necessary to push the socket block 21 to move it towards the side away from the second moving plate 25 and continue to compress the second compression spring 20 on the support pipe 19 until one end of the socket block 21 is removed from a pair of docking grooves 22 on the second moving plate 25, thereby releasing the limit of the socket block 21 on the second moving plate 25. Then, turn the second moving plate 25 upwards (combined with Figure 2 as shown), expose the upper end of the circulating pump body 3, and then overhaul its upper end;

[0029] Step 3: When overhauling the side of the circulating pump body 3 away from the chassis 1, it is necessary to pull the moving frame 13 towards the end away from the third moving plate 7, so that one end of it will continue to stretch the tension spring 12, and at the same time it will drive the limit pipe 14 to move together until one end of the limit pipe 14 is removed from the limit groove 15 on the third moving plate 7, thereby releasing the limit of the limit pipe 14 on the third moving plate 7. Then, manually move the third moving plate 7 upwards to separate it from the protective cover 5, so as to expose the end of the circulating pump body 3 away from the chassis 1, and then overhaul the end of the circulating pump body 3 away from the chassis 1;

[0030] In summary, when the circulating pump is in use, it can not only be isolated from external forces and reduce the damage caused by external forces, but also facilitate personnel to overhaul its different sides.

[0031] The second embodiment:

[0032] On the basis of the first embodiment, the following structure is newly added, and the rest is the same as the first embodiment, specifically as follows:

[0033] Figure 2 As shown in Figure 5 a plurality of threaded pipes 26 are threadedly connected to the outer end of the mounting seat 2, an installation block 27 is fixedly connected to the side end of the threaded pipe 26, and a plurality of installation grooves 28 for the installation block 27 to be movably inserted are opened on the outer end of the protective cover 5.

[0034] A plurality of storage grooves (not shown in the figure) that are movably inserted with the mounting blocks 27 are formed on the inner wall of the mounting base 2, and the storage grooves communicate with the threaded holes formed at the outer end of the mounting base 2 and adapted to the threaded pipe 26. After inserting the lower end of the protective cover 5 into the insertion groove 4, rotate the threaded pipe 26 to drive the mounting block 27 to move towards the protective cover 5 together, and then push the mounting block 27 out of the storage groove (before inserting the lower end of the protective cover 5 into the insertion groove 4, the end of the mounting block 27 away from the threaded pipe 26 is flush with the inner side wall of the mounting base 2), until the mounting block 27 is pushed into the mounting groove 28 on the protective cover 5. The mounting block 27 is used to limit the position of the protective cover 5, improve its stability on the mounting base 2, and prevent it from being easily removed from the insertion groove 4 and separated from the mounting base 2 when subjected to force.

[0035] Combined with the current actual requirements, the above-described implementation manner adopted in this application does not limit the scope of protection thereto. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
