Technical Field
[0001] The utility model relates to the technical field of ancient building restoration equipment, in particular to a cleaning device for the interior of a hollow wooden column of a cultural relic ancient building. Background Art
[0002] Ancient buildings have important commemorative significance and historical value. During the long process of preservation, ancient buildings have suffered varying degrees of damage due to human and natural forces. Among them, the wooden columns of wooden-structured ancient buildings are prone to problems such as internal hollowness, cracking, and decay under long-term loading and natural environment erosion, posing potential hazards to the structural stability and safety of ancient buildings. In cultural relic protection, when repairing wooden columns, it is necessary to clean the rotten parts on their surfaces. However, due to the narrow space and large depth inside the hollow wooden columns, ordinary cleaning tools cannot reach, and a special device is needed to comprehensively and effectively clean the rotten parts inside the wooden columns without damaging the unrotten wood, so as to protect the cultural relic building components to the greatest extent.
[0003] In order to increase the working range of the existing high-pressure water gun and ensure that the flushing direction will not change due to the impact of high-pressure water flow, it is connected by a stainless steel straight pipe between the gun body and the nozzle. However, in the scenario of repairing ancient building wooden columns, the rotten parts inside the wooden columns are generally distributed along the axial direction of the wooden columns. Therefore, there is an angular position between the opening formed by the rotten part on the outer peripheral surface of the wooden column and the part inside the wooden column. Since the stainless steel straight pipe of the existing high-pressure water gun does not have the ability to deform, it is difficult for the nozzle of the high-pressure water gun to extend from the opening on the outer peripheral surface of the wooden column to the deep part of the rotten part inside the wooden column, making it difficult to flush the deep part of the rotten part clean. Therefore, a new cleaning device needs to be proposed to solve the above technical problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a cleaning device for the interior of a hollow wooden column of a cultural relic ancient building, which can more easily extend the nozzle to the deep part of the rotten part, making flushing more convenient and having a better flushing effect.
[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows: A cleaning device for the interior of a hollow wooden column of a cultural relic ancient building, comprising a connecting pipe, a switching valve, a sizing nut, a nozzle, and a liquid pumping module; the switching valve is installed on the liquid pumping module, the input port of the switching valve is communicated with the output port of the liquid pumping module, an installation head is formed on the switching valve, the installation head is a cylindrical structure arranged along the output port of the switching valve, and a threaded section is formed on the outer peripheral surface of the installation head; the connecting pipe includes an inner pipe and a plurality of sleeves; the inner pipe is a flexible pipe, one end of the inner pipe is communicated with the nozzle, and the other end of the inner pipe passes through the inner cavity of the installation head and is communicated with the output port of the switching valve; the sleeves are rigid pipes, and a plurality of sleeves are sleeved on the inner pipe in sequence along the axial direction of the inner pipe, and two adjacent sleeves are rotatably connected through a spherical surface; the sizing nut is threadedly connected to the threaded section of the installation head, and the sizing nut can be switched between a locked state and an unlocked state by rotation.

[0006] The working principle of the present utility model:
[0007] Before the cleaning work is carried out, the sizing nut is rotated and moved away from the sleeve direction, so that the nozzle, the sleeve, and the sizing nut are no longer in close contact, so that two adjacent sleeves can rotate relative to each other, and since the inner pipe is a flexible pipe, the connecting pipe can be bent in segments, so that the nozzle can be placed deep into the rotten part inside the ancient building wooden column. After the nozzle is placed, the sizing nut is rotated and moved towards the sleeve direction and pressed against the adjacent sleeve. Under the clamping action of the sizing nut and the nozzle, two adjacent sleeves are squeezed against each other and clamped and fixed, so that the shape of the connecting pipe is fixed. At this time, the switching valve is opened, and the liquid pumping module transports the external liquid to the nozzle through the inner pipe of the connecting pipe, and the nozzle sprays and flushes the inside of the wooden column. Since the sleeves of the connecting pipe are sized due to mutual extrusion, the connecting pipe will not swing due to the impact of high-pressure fluid on the inner wall of the inner pipe, so as to ensure that the spraying direction of the nozzle remains unchanged.
[0008] Further, for a cleaning device for the interior of a hollow wooden column of a cultural relic ancient building as described above, engaging textures are formed on both end faces of each sleeve. In the locked state, between two adjacent sleeves: the engaging texture of one sleeve can be engaged and positioned by mutually squeezing with the engaging texture of the other sleeve.
[0009] Further, for a cleaning device for the interior of a hollow wooden column of a cultural relic ancient building as described above, the diameter of the sleeve is less than or equal to the maximum diameter of the nozzle.

[0011] Further, for a cleaning device for the interior of a hollow wooden column of an ancient cultural relic building as described above, it further includes a reinforcing rib. The reinforcing rib has the ability to bend and deform. The reinforcing rib is arranged between the inner tube and the sleeve. One end of the reinforcing rib is connected to the mounting head, and the other end of the reinforcing rib is connected to the nozzle.

A number of water outlets are formed on the small-end end face and the outer circumferential surface of the diversion head, and each water outlet is communicated with the diversion cavity; one end of the inner tube is communicated with the diversion cavity.
[0014] Further, for a cleaning device for the interior of a hollow wooden column of an ancient cultural relic building as described above, it further includes a movable chassis.

Detailed implementation manners
[0023] For a clearer understanding of the technical features, purposes, and effects of the present utility model, the detailed implementation manners of the present utility model will now be described in detail with reference to the accompanying drawings.
[0024] As Figures 1 to 4 A cleaning device for the interior of a hollow wooden column of a cultural relic ancient building as an embodiment includes a connecting pipe 1, a switching valve 2, a sizing nut 3, a nozzle 4, and a liquid pumping module 6; the switching valve 2 is installed on the liquid pumping module 6, the input port of the switching valve 2 is communicated with the output port of the liquid pumping module 6, a mounting head 21 is formed on the switching valve 2, the mounting head 21 is a cylindrical structure arranged along the output port of the switching valve 2, and a threaded section 22 is formed on the outer peripheral surface of the mounting head 21; the connecting pipe 1 includes an inner pipe 11 and a plurality of sleeves 12; the inner pipe 11 is a flexible pipe, one end of the inner pipe 11 is communicated with the nozzle 4, and the other end of the inner pipe 11 passes through the inner cavity of the mounting head 21 and is communicated with the output port of the switching valve 2; the sleeve 12 is a rigid pipe, and a plurality of sleeves 12 are sleeved on the inner pipe 11 in sequence along the axial direction of the inner pipe 11, and two adjacent sleeves 12 are rotatably connected through a spherical surface; the sizing nut 3 is threadedly connected to the threaded section 22 of the mounting head 21, and the sizing nut 3 can be switched between a locked state and an unlocked state by rotation. In the locked state: a plurality of sleeves 12 are clamped between the sizing nut 3 and the nozzle 4 for clamping and sizing; the liquid pumping module 6 is a water pump, the input port of the liquid pumping module 6 is communicated with an external liquid storage container or an automatic water pipeline, and the liquid pumping module 6 is used to extract and pressurize external liquid and output it from its output port.
[0025] The working principle of the present utility model:
[0026] Before the cleaning work is carried out, the sizing nut 3 is moved away from the sleeve 12 by rotation, so that the nozzle 4, the sleeve 12, and the sizing nut 3 are no longer in close contact, so that the adjacent two sleeves 12 can rotate relative to each other. And since the inner tube 11 is a flexible tube, the connecting tube 1 can be bent in sections, so that the nozzle 4 can be placed deep into the decayed part of the ancient building wooden column. After the nozzle 4 is placed, the sizing nut 3 is moved towards the sleeve 12 by rotation and pressed against the adjacent sleeve 12. Under the clamping action of the sizing nut 3 and the nozzle 4, the adjacent two sleeves 12 are squeezed against each other and clamped and fixed, so that the shape of the connecting tube 1 is fixed. At this time, the switch valve 2 is opened, and the liquid pumping module 6 transports the external liquid to the nozzle 4 through the inner tube 11 of the connecting tube 1. The nozzle 4 sprays and flushes the inside of the wooden column. Since the sleeves 12 of the connecting tube 1 are shaped by mutual extrusion, the connecting tube 1 will not swing due to the impact of high-pressure fluid on the inner wall of the inner tube 11, so as to ensure that the spraying direction of the nozzle 4 remains unchanged.
[0027] As Figure 4 shown, the diameter of the sleeve 12 is smaller than the maximum diameter of the nozzle 4. Engaging textures are formed on both end faces of each sleeve 12. When in the locked state, between each adjacent two sleeves 12: the engaging texture of one sleeve 12 can be engaged and positioned by mutually squeezing with the engaging texture of the other sleeve 12. By providing the engaging textures, the sizing structure between each adjacent two sleeves 12 can be made more stable.

With such a structure, it is convenient for the user to rotate the positioning and sizing nut 3 to switch the state of the positioning and sizing nut 3.
[0029] As Figures 2 to 4 shown, this embodiment further includes a reinforcing rib 5. The reinforcing rib 5 has the ability of bending deformation. The reinforcing rib 5 is arranged between the inner tube 11 and the sleeve 12. One end of the reinforcing rib 5 is connected to the mounting head 21, and the other end of the reinforcing rib 5 is connected to the nozzle 4. With such a structure, the connection structure between the nozzle 4 and the mounting head 21 can be made more stable, ensuring that the sizing nut 3 has a good clamping effect on the sleeve.
[0030] As Figure 2 and Figure 3 shown, the sizing nut 3 and the adjacent sleeve 12 are connected by a spherical surface. With such a structure, the connecting tube 1 can have a certain included angle relative to the mounting head 21 after being sized, making the shape change of the connecting tube 1 more flexible.
[0031] As Figure 1 、Figure 2 and Figure 4 As shown in Figure 4 , the spray head 4 includes a mounting base 41 and a diversion head 42; the outer contour of the diversion head 42 is a frustum structure, the diversion head 42 is on the side of the mounting base 41 facing away from the sleeve 12, and the large-end end face of the diversion head 42 is connected to the mounting base 41, so that a diversion cavity 43 is formed by enclosing the diversion head 42 and the mounting base 41. A plurality of water outlets 44 are formed on the small-end end face and the outer circumferential surface of the diversion head 42, and each water outlet 44 communicates with the diversion cavity 43; one end of the inner tube 11 communicates with the diversion cavity 43. With such a structure, the liquid spraying and cleaning coverage range of the spray head 4 can be made larger, and the cleaning efficiency can be improved.
[0032] As Figure 1 and Figure 2 shown in Figure 2 , this embodiment further includes a mobile chassis 7. Pulley 72s are rotatably installed on the left and right sides of the mobile chassis 7 respectively. The two pulley 72s are arranged close to the rear side of the mobile chassis 7.
