[0034] The supporting assembly 3 comprises a mounting plate 3.1 fixed to the bobbin 1, and a mounting tube 3.2 is fixed to the mounting plate 3.1;

[0035] The cooling assembly 4 includes a shunt pipe 4.1 fixed to the inner wall of the installation cylinder 3.2, the pipe body of the shunt pipe 4.1 forms a spiral structure on the inner wall of the installation cylinder 3.2 that can be spirally adapted to the threaded receiving cylinder 2, the water inlet end of the shunt pipe 4.1 is connected to the cylinder tube 1, and the water outlet end of the shunt pipe 4.1 extends out of the installation cylinder 3.2;

[0036] Specifically, the tube 1 is a tube body with the same ends, one end of the tube mouth of the tube 1 is connected to the water delivery pipeline, the threaded receiving tube 2 is a sealed tube body to prevent the splashing of external water flow from affecting the monitoring camera terminal circuit board block, the side of the mounting plate 3.1 is fixed to the side of the tube 1, and the outer side surface of the mounting tube 3.2 is fixed to the board surface of the mounting plate 3.1;

[0037] During actual use, the threaded receiving tube 2 is spirally inserted into the mounting tube 3.2. At this time, the spiral pattern on the threaded receiving tube 2 is spirally engaged with the spiral structure in the mounting tube 3.2, thereby completing the installation of the threaded receiving tube 2 on the barrel 1. For disassembly, the above operation can be reversed. When the barrel 1 is spraying water, a part of the water flows into the diversion tube 4.1. The water flows in the diversion tube 4.1, thereby exchanging heat with the threaded receiving tube 2, and then absorbing and taking away the heat generated by the threaded receiving tube 2, thereby achieving cooling of the environment in which the threaded receiving tube is located, improving the heat dissipation effect of the monitoring camera terminal in the threaded receiving tube, and helping to extend the service life of the monitoring camera terminal.

[0038] In another embodiment provided by the present invention, the threaded receiving tube 2 includes a tube body 2.1, the axis of the tube body 2.1 is parallel to the axis of the tube tube 1, the outer part of the tube body 2.1 is spirally wound with a heat conductive sheet 2.2, and the heat conductive sheet 2.2 forms a spiral pattern on the outer part of the tube body 2.1, and a sealing plate 2.3 is fixed to the tube mouth end of the tube body 2.1, so as to seal the tube mouth of the tube body 2.1 and ensure that the inside of the tube body 2.1 has good waterproofness.

The sealing plate 2.3 The plate body can completely cover the barrel mouth of the cylinder 2.1, and the plate body of the sealing plate 2.3 and the barrel mouth of the cylinder 2.1 are detachably sealed. For example, a threaded protrusion is provided on the outside of the barrel mouth end of the cylinder 2.1, and a spiral groove blind opening adapted to the end of the cylinder 2.1 is provided on the plate surface of the sealing plate 2.3. The barrel mouth end of the cylinder 2.1 is spirally inserted into the spiral groove blind opening, similar to the principle of screwing a cup and a cup lid. It is not repeated here. The bottom of the cylinder 2.1 is light-transmitting. The thermal imaging sensor, camera and other imaging elements on the monitoring camera terminal can monitor the external environment through the bottom of the cylinder 2.1.

[0039] In another embodiment provided by the present invention, the axis line of the mounting tube 3.2 is parallel to the axis line of the bobbin 1, and one end of the mounting tube 3.2 can be blocked by the sealing plate 2.3, which is beneficial to prevent external debris from entering the mounting tube 3.2 and plays an isolation role, ensuring that the threaded accommodating tube 2 can be normally screwed in the bobbin 1. At the same time, when the sealing plate 2.3 blocks the end of the mounting tube 3.2, the threaded accommodating tube 2 reaches the maximum plug-in position in the mounting tube 3.2.

[0040] In another embodiment provided by the present invention, a locking assembly 5 is provided on the mounting tube 3.2. The locking assembly 5 has a locked state and an unlocked state. When the locking assembly 5 is in the locked state, the axial deflection of the threaded accommodating tube 2 in the mounting tube 3.2 is limited, thereby increasing the installation stability of the threaded accommodating tube 2 in the mounting tube 3.2. When the locking assembly 5 is in the unlocked state, the axial deflection of the threaded accommodating tube 2 in the mounting tube 3.2 is released.

[0041] Specifically, the locking assembly 5 includes a plurality of limiting grooves 5.1 formed on the outer side of the cylinder 2.1, the length direction lines of the limiting grooves 5.1 are parallel to the axis line of the cylinder 2.1, and the limiting grooves 5.1 are evenly distributed on the outer side of the cylinder 2.1. The locking assembly 5 also includes a pin 5.2 movably plugged into the mounting tube 3.2, the extension line of the axis line of the pin 5.2 is perpendicular to the axis line of the cylinder 2.1, the rod body of the pin 5.2 movably penetrates the tube wall of the mounting tube 3.2, the pin 5.2 is connected to the inner wall of the mounting tube 3.2 by a tension spring 5.3, in the unlocked state, the tension spring 5.3 is in a contracted state, and the insertion end of the pin 5.2 is separated from the limiting groove 5.1;

[0042] Furthermore, the locking assembly 5 further comprises a thrust unit 5.4, which can clamp the pin 5.2 with the corresponding limiting groove 5.1 in a pressure-applying state to limit the rotation of the threaded receiving tube 2, and at this time, the locking assembly 5 is in a locked state;

[0043] Specifically, the thrust unit 5.4 includes a collar 5.41 that can be movably sleeved on the mounting tube 3.2, and an inclined portion 5.42 is provided on the inner wall of the collar 5.41. The inclined portion 5.42 is an annular inclined portion, and a spiral groove 5.43 that can be spirally adapted to the end of the pin rod 5.2 is provided on the inclined portion 5.42.

[0044] In actual use, the collar 5.41 is movably sleeved on the mounting tube 3.2. At this time, the end of the pin 5.2 contacts the inclined portion 5.42. At this time, the collar 5.41 is rotated along the axis of the mounting tube 3.2. At this time, the end of the pin 5.2 slides relatively along the groove body of the spiral groove 5.43. The collar 5.41 is spirally sleeved on the mounting tube 3.2. As the collar 5.41 continues to rotate, the collar 5.41 also slides along the axis of the mounting tube 3.2. When the locking assembly 5.2 is in a state of being pressed, the locking assembly 5.4 is in a state of being released from the locking mechanism 3.2 and the locking element 5.5 is in a state of being released from the locking mechanism 3.2.

[0045] In another embodiment provided by the present invention, a blocking assembly 6 is provided on the mounting tube 3.2, and the blocking assembly 6 includes a front end blocking unit, a rear end blocking unit and a connecting unit, the rear end blocking unit is a blocking plate 2.3, the connecting unit is a thrust unit 5.4, and the front end blocking unit includes a transparent plate 6.11 installed with the collar 5.41;

[0046] During actual use, when the threaded accommodating tube 2 reaches the maximum plug-in position in the mounting tube 3.2, the sealing assembly 6 can seal the two ends of the mounting tube 3.2. Specifically, the sealing plate 2.3 seals one end of the mounting tube 3.2. When the thrust unit 5.4 is in a pressure state, the transparent plate 6.11 and the collar 5.41 form a seal at the other end of the mounting tube 3.2, which is beneficial to prevent external debris from entering the mounting tube 3.2, and plays an isolation role, ensuring that the threaded accommodating tube 2 can be normally screwed in the tube 1. At the same time, it also assists in waterproofing the threaded accommodating tube 2 and increases the collision protection effect.

[0047] In another embodiment provided by the present invention, a rotating ring 6.12 is rotatably mounted on the ring body of the collar 5.41, the ring body of the rotating ring 6.12 protrudes from the end face of the collar 5.41, the center of the rotating ring 6.12 coincides with the center of the collar 5.41, the inner ring surface of the rotating ring 6.12 is fixed to the circumferential surface of the transparent plate 6.11, the transparent plate 6.11 is a circular plate adapted and fixed to the inner ring surface of the rotating ring 6.12, the transparent plate 6.11 can be a transparent and light-transmitting visible plate or lens such as a high-temperature resistant glass plate or a high-temperature resistant acrylic plate, a plurality of evenly distributed ratchet blocks 6.13 are fixed to the ring mouth end of the rotating ring 6.12, a cleaning unit 6.14 hinged to the collar 5.41 is provided on the outer surface of the transparent plate 6.11, and the cleaning unit 6.14 can clean the transparent plate 6.11 when performing a cleaning movement;

[0048] Specifically, the cleaning unit 6.14 includes a rod 6.141 hingedly mounted on the end of the collar 5.41, the rod 6.141 has a vertical equilibrium position, a cleaning strip 6.142 is fixed on the rod body of the rod 6.141, the cleaning strip 6.142 is located within the ring surface of the collar 5.41, a blade 6.143 is fixed to the protruding end of the rod 6.141, the blade 6.143 is perpendicular to the ring surface of the collar 5.41, the blade 6.143 is located below the collar 5.41, the protruding end of the rod 6.141 refers to the rod body portion located outside the ring surface of the collar 5.41, and the rod 6.141 reciprocates on the collar 5.41 to make the cleaning unit 6.14 perform a cleaning motion;

[0049] It should be noted that springs 6.144 are fixed on both sides of the blade 6.143, and the ends of each spring 6.144 are fixed to the collar 5.41 through a connecting block 6.145. When the spring 6.144 is in a natural state, the elastic support force of the spring 6.144 makes the rod 6.141 have a vertical equilibrium position. In addition, a guide pipe 4.2 is fixed on the water outlet end of the diverter pipe 4.1, and the guide pipe 4.2 can flush the water flow in the diverter pipe 4.1 toward the blade 6.143.

[0050] In actual use, when the guide tube 4.2 directs the water flow vertically toward the plate surface of the blade 6.143, the blade 6.143 drives the rod 6.141 to deflect forward on the collar 5.41 around the hinge position, and the spring 6.144 is elastically deformed. Then, under the elastic restoring force of the spring 6.144, the rod 6.141 is reset toward the equilibrium position, that is, the rod 6.141 is reversely deflected on the collar 5.41 around the hinge position, and the rod 6.141 drives the cleaning strip 6.142 to swing back and forth on the transparent plate 6.11 to wipe off attachments, such as water stains, dust, etc., so that the transparent plate 6.11 has a good light transmission field.

[0051] In addition, during the reciprocating swing of the rod 6.141, when the rod 6.141 is deflected in the positive direction, the rod 6.141 and the ratchet block 6.13 are in one-way meshing transmission, so that the rotating ring 6.12 is rotated on the sleeve ring 5.41, so that the transparent plate 6.11 is also rotated accordingly, which is conducive to avoiding the same position from being reciprocated and wiped and cleaned, and reducing the wear of the transparent plate 6.11. When the rod 6.141 is deflected in the reverse direction, the rod 6.141 will not be in meshing transmission with the ratchet block 6.13;

[0052] In other words, when the rod 6.141 swings, a fan-shaped cleaning area is formed on the transparent plate 6.11, and the area of ​​the cleaning area occupies between one-third and one-twelfth of the area of ​​the transparent plate 6.11. For example, the cleaning area occupies thirty-six percent of the area of ​​the transparent plate 6.11. When the rod 6.141 swings, it can intermittently drive the rotating ring 6.12 in one direction, so that each part of the transparent plate 6.11 can enter the cleaning area in turn for cleaning, which is beneficial to avoid the same position being wiped and cleaned back and forth, reducing the wear of the transparent plate 6.11. On the other hand, it also avoids the rod 6.141 from blocking the field of view of the camera and other framing devices on the monitoring camera terminal, and has a good framing angle.

[0053] In another embodiment provided by the present invention, the axis center line of the guide tube 4.2 is parallel to the horizontal plane, the tube body of the guide tube 4.2 is located directly below the collar 5.41, and a plurality of evenly distributed plug-in slots 7 are provided on the circumferential surface of the ring body of the collar 5.41. A pin 8 is movably plugged into the top of the tube body of the guide tube 4.2, and a buoyancy block 9 is fixed on one end of the pin 8 located inside the guide tube 4.2, and a first magnet sheet 10 is fixed on the top surface of the buoyancy block 9, and a second magnet sheet 11 that can be magnetically attracted to the first magnet sheet 10 is fixed on the inner top wall of the guide tube 4.2. In actual use, when water flows through the guide tube 4.2, the buoyancy block 9 drives the pin 8 to rise under the action of the buoyancy of the water flow, so that the pin 8 is inserted into the plug-in slot 7, thereby limiting the rotation of the collar 5.41, which is beneficial to prevent the thrust unit 5.4 from loosening and further improve the overall stability of the fastening mechanism; when the water in the guide tube 4.2 is evacuated, the first magnet sheet 10 and the second magnet sheet 11 are magnetically attracted, and the pin 8 is still inserted into the plug-in slot 7, thereby improving the overall stability of the fastening mechanism;

[0054] It should be particularly noted that a sleeve 12 is rotatably sleeved on one end of the rod 6.141 away from the blade 6.143, a limit opening 13 is provided on the tube body of the sleeve 12, a limit block 14 fixed to the rod 6.141 is provided in the limit opening 13, and a ratchet piece 15 capable of unidirectional meshing with the ratchet block 6.13 is fixed to the outside of the tube body of the sleeve 12, so that when the rod 6.141 is positively deflected, the rod 6.141 and the ratchet block 6.13 are unidirectionally meshed and transmitted, and the limit block 14 is in contact with the edge of the limit opening 13, so as to provide support force for the ratchet piece 15 and the ratchet block 6.13 to contact and squeeze;

[0055] When the rod 6.141 deflects in the reverse direction, the limit block 14 is separated from the edge of the limit opening 13, and the limit block 14 is located in the limit opening 13. At this time, the rod 6.141 will not be meshed with the ratchet block 6.13.

[0056] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
