Description

Technical Field

[0001] This utility model relates to the field of municipal water supply network technology, specifically to a high-efficiency flushing device for municipal water supply networks. Background Technology

[0002] Municipal water supply networks are an important part of urban infrastructure, responsible for the safe and efficient delivery of clean drinking water from water sources (such as reservoirs, rivers or groundwater) to various areas of the city to meet the water needs of residents, industrial production and public facilities.

[0003] The prior art discloses a high-efficiency flushing device for municipal water supply networks, with announcement number CN222314126U. The device includes a flushing head, a connecting pipe fixedly connected to one end of the flushing head, a slot on the outer wall of the connecting pipe, and an arc-shaped locking block movably connected within the slot. A connecting pipe is movably connected to the end of the connecting pipe away from the flushing head, with a telescopic groove inside the connecting pipe. A locking groove is formed on one side of the arc-shaped locking block, communicating with the telescopic groove. A locking pin is engaged within the locking groove, and a pull rod is fixedly connected to one end of the locking pin. The pull rod is slidably connected to the connecting pipe, and a spring is sleeved on the outer surface of the pull rod. By engaging the locking pin with the locking groove, the arc-shaped locking block can be locked, thus fixing the connecting pipe and the connecting pipe and ensuring the stability of the flushing head during use. Furthermore, the use of the pull rod and spring pad allows for quick replacement of the connecting pipe and the connecting pipe, improving the installation speed of the flushing head and increasing work efficiency.

[0004] One end of the aforementioned flushing head is fixedly connected to a connecting pipe. By pushing the connecting pipe to move, the flushing head is inserted into the water supply network. This makes it easy for the flushing head to collide with the inner wall surface of the water supply network, which can damage the flushing head and make it more frequently replaced, requiring a lot of time.

[0024] 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.

[0025] Please see Figure 1-4 The present invention provides the following technical solution:

[0026] A high-efficiency flushing device for municipal water supply networks includes a rolling device 1 and a flushing head 3. A water spray pipe 2 is welded to the side wall near the bottom of the flushing head 3, and the rolling device 1 is disposed on the bottom surface of the flushing head 3.

[0027] The rolling device 1 includes a connecting water pipe 11, a flange 14 welded to the top of the connecting water pipe 11, a fastening bolt 12 threaded to the outward end of the flange 14, a connecting component 13 threaded to the surface of the fastening bolt 12, and the connecting water pipe 11 threaded to the bottom end of the flushing head 3. The connecting water pipe 11 and the flushing head 3 are threadedly connected, allowing the flushing head 3 to perform water spraying operations through the water spray pipe 2, which facilitates flushing operations inside the municipal water supply network and keeps the inner wall surface of the municipal water supply network clean.

[0028] The connecting assembly 13 includes two connecting blocks 131, which are distributed left and right. One end of each connecting block 131 has a threaded groove, which is threadedly connected to a fastening bolt 12 to lock and fix the flange 14 and the connecting block 131, facilitating the disassembly of the connecting block 131. The connecting block 131 is movably connected to the surface of the connecting water pipe 11 and is located on the top surface of the flange 14. The fastening bolt 12 thread-fixes the connecting block 131 and the flange 14, determining the position of the connecting block 131, facilitating the disassembly of the connecting block 131, and protecting the safety of the connecting block 131.

[0029] A telescopic rod 132 is installed on the outer side surface of the connecting block 131. A fastening bolt 12 is threadedly connected to the inner end of the connecting block 131. The fastening bolt 12 locks and fixes the connecting block 131 and the flange 14, which facilitates the disassembly of the connecting block 131, protects the safety of the connecting block 131, and avoids damage to the connecting block 131.

[0030] The telescopic rod 132 is threaded with a second fastening bolt 137 at its outward end. A connecting frame 133 is installed on the outward side surface of the telescopic rod 132. A rotating roller 134 is installed at the outward end of the connecting frame 133. There are four second fastening bolts 137. Two second fastening bolts 137 form a group, and the two groups of second fastening bolts 137 are distributed left and right. The two second fastening bolts 137 in the same group are distributed at the front and rear ends of the connecting frame 133. The second fastening bolts 137 lock and fix the connecting frame 133 and the telescopic rod 132, making it easy to disassemble the connecting frame 133 and the rotating roller 134.

[0031] A helical spring 135 is installed in the middle of the connecting frame 133, and an electric push rod 136 is set in the middle of the connecting frame 133. The helical spring 135 is set in the middle of the outer surface of the connecting block 131, and the electric push rod 136 is set in the middle of the outer surface of the connecting block 131. The electric push rod 136 is located inside the helical spring 135. The connecting block 131 determines the position of the helical spring 135 and the electric push rod 136, and then adjusts the position of the connecting frame 133.

[0032] When in use, push the connecting water pipe 11 to move it, so that the connecting water pipe 11 drives the flushing head 3 and the spray pipe 2 to be inserted into the municipal water supply network. Inject clean water into the connecting water pipe 11 and the flushing head 3, and let the clean water spray through the spray pipe 2 to perform the cleaning operation, so that the clean water can clean the inside of the municipal water supply network.

[0033] The connecting water pipe 11 drives the connecting block 131 to move inward, so that the connecting block 131 is inserted into the municipal water supply network through the telescopic rod 132, the spiral spring 135 and the electric push rod 136, so that the rotating roller 134 moves on the inner wall surface of the municipal water supply network, making the movement of the spray pipe 2 and the flushing head 3 smoother. After cleaning, the connecting water pipe 11 is pulled outward, so that the connecting water pipe 11, the spray pipe 2 and the flushing head 3 are detached from the municipal water supply network.

[0034] Rotate fastening bolt 12 to disengage it from connecting block 131 and flange 14, loosening the connection between them. Then rotate the threaded rod to disengage it from connecting block 131, facilitating disassembly of the connecting block 131.

[0035] Pull the connecting block 131 outward, and the connecting block 131 slides on the surface of the flange 14, allowing the connecting block 131 to detach from the flange 14 and the connecting water pipe 11, making it convenient to replace the connecting block 131 and the flange 14.

[0036] The connecting block 131 is movable outward. The connecting block 131 drives the rotating roller 134 to move outward through the telescopic rod 132, the connecting frame 133 and the fastening bolt 137, which facilitates the maintenance of the connecting block 131 and the telescopic rod 132, and facilitates the replacement of the rotating roller 134 and the telescopic rod 132.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
