Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a device and a method for accurately locating a blockage point of a building electrical bushing. Background Art

[0002] Casings, usually used in building basements, are iron rings used to protect pipes or facilitate pipe installation. Casings are classified into rigid casings, flexible waterproof casings, steel pipe casings, and iron casings. In construction, the use of casings is also very useful. They can protect wires in the wall and prevent leakage when quality problems occur in the wires, thereby causing harm to residents.

[0003] Due to various reasons such as people stepping on it when pouring concrete and the vibrator breaking, the casing often becomes blocked. Since the casing is hidden in the floor or wall and cannot be seen, the traditional method is to use a steel wire to pass into the pipe, and after probing the blockage point, the blockage point is located by measuring the length of the steel wire inserted into the casing on the wall or floor surface. However, this method can only determine the approximate range of the blockage point, but cannot accurately locate it. Moreover, when the blockage point is low, the length of the infiltrated steel wire is long, and its end is easy to hit the side wall of the casing and bend it, resulting in a wrong judgment of the blockage point, causing errors in the measurement and positioning of the blockage point, and increasing the amount of work to dig the blockage point. Therefore, there is a situation where the efficiency of finding the blockage point is low and the location of the blockage point is not accurate enough, which affects the progress of the construction. To this end, we propose a device and method for accurately locating the blockage point of the building electrical casing. Summary of the invention

[0004] The purpose of the present invention is to provide a precise positioning device and positioning method for a blockage point of a building electrical bushing, so as to solve the problem that the existing electrical bushing blockage positioning device proposed in the above background technology has low efficiency in finding the blockage point and the position of the blockage point is not accurate enough, which affects the progress of the building construction.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The present invention provides a technical solution: a device and method for accurately locating the blockage point of a building electrical bushing. The existing electrical bushing blockage locating device has low efficiency in finding the blockage point and the position of the blockage point is not accurate enough, which affects the progress of the building construction. The technical solution specifically includes the following steps:

[0027] S1; first, a sliding assembly 3 with a lifting rope 2 is inserted into the electrical bushing 1;

[0028] S2; sequentially rotate the detection assembly 4 and the air pump 5 at the end of the electrical bushing 1, and pass the pull rope 2 through the corresponding hole groove on the detection assembly 4;

[0029] S3; turn on the air pump 5, record the speed of the detection wheel 44 within a certain period of time, and record;

[0030] S4; the movement distance of the sliding assembly 3 is equal to the rotation speed of the detection wheel 44 per unit time.

[0031] See also Figure 1-4 The positioning device includes an electrical bushing 1, and the open end of the electrical bushing 1 is connected with a detection component 4 in turn through threads. The detection component 4 can detect the movement distance of the sliding component 3 inside the electrical bushing 1.

[0032] like Figure 2 and Figure 5 The detection assembly 4 includes a detection shell 40, a fixed rod 41 and a movable sleeve 42. The movable sleeve 42 is movably connected to the fixed rod 41. The end of the movable sleeve 42 away from the fixed rod 41 is connected to a detection wheel 44 through a pin shaft. The detection wheel 44 includes a roller and a speed detector arranged on the roller shaft. The rotation speed of the roller can be detected in real time through the speed detector.

[0033] Furthermore, a second spring member 43 is provided between the fixed rod 41 and the movable sleeve 42, and the second spring member 43 is movably sleeved on the fixed rod 41. The second spring member 43 is provided so that the detection wheel 44 is always in contact with the lifting rope 2, and the detection wheel 44 can rotate when the lifting rope 2 is pulled. The surface of the detection wheel 44 is provided with axial anti-slip grooves, so that the detection wheel 44 can effectively rotate when the lifting rope 2 is pulled.

[0034] Furthermore, an air pump 5 is threadedly connected to one end of the detection component 4 away from the electrical bushing 1, and a sliding component 3 is movably arranged inside the electrical bushing 1. The air pump 5 can fill the electrical bushing 1 with air, thereby providing power for the movement of the sliding component 3 inside the electrical bushing 1.

[0035] See also Figure 2-4 The sliding assembly 3 includes a sliding sleeve 30, which is distributed in an annular shape, and the outer side of the sliding sleeve 30 is inclined toward the side away from the air pump 5. The sliding sleeve 30 is arranged to be inclined at a certain angle, which can facilitate the movement of the sliding sleeve 30 inside the electrical bushing 1.

[0036] Furthermore, adjacent sliding sleeves 30 are connected by a corrugated folding piece 31, wherein the corrugated folding piece 31 is made of a corrugated hose material, which can fold the corrugated folding piece 31 when the sliding sleeve 30 is squeezed, thereby alleviating the squeezing of the sliding sleeve 30, and a plug-in rod 32 is fixedly installed on the inner side of the sliding sleeve 30, which ensures the service life of the sliding sleeve 30 and facilitates the movement of the sliding component 3 inside the electrical sleeve 1.

[0037] Furthermore, a fixed sleeve 33 is provided inside the circular ring formed by adjacent sliding sleeves 30, and the plug rod 32 is movably plugged into the fixed sleeve 33. The fixed sleeve 33 is provided with a limiting hole 35 for plugging the plug rod 32, and a conical sleeve 36 is provided at the opposite end of the fixed sleeve 33 and the air pump 5. The setting of the conical sleeve 36 can make the gas emitted by the air pump 5 fully act on the conical sleeve 36, thereby driving the entire sliding assembly 3 to move inside the electrical bushing 1, ensuring the convenience of locating the precise point of the electrical bushing blockage in the building.

[0038] Furthermore, a first spring member 34 is provided inside the limiting hole groove 35, wherein the provision of the first spring member 34 allows the sliding component 3 to be adjusted in real time inside the electrical bushing 1 according to the size of the internal space of the electrical bushing 1, thereby ensuring that the sliding component 3 can pass smoothly.

[0039] Specifically, the first spring member 34 is disposed on the inner side of the adjacent plug rod 32. The fixed sleeve 33, the conical sleeve 36 and the middle of the detection housing 40 are all provided with a rope threading hole 61, which is a through hole. A pull rope 2 is disposed inside the rope threading hole 61. The wire and the pull rope 2 are passed through the rope threading hole 61, and the pull rope 2 passes through the detection housing 40 and extends outward, and the pull rope 2 is fixedly installed with the sliding assembly 3. Specifically, the pull rope 2 can be connected and fixed with the conical sleeve 36.

[0040] Working principle: Before using this kind of device for accurately locating the blockage point of building electrical bushings, first put the sliding component 3 as a whole into the electrical bushing 1, and place the suspended end of the lifting rope 2 connected to the sliding component 3 on the outside of the electrical bushing 1; screw the detection component 4 and the air pump 5 into the end of the electrical bushing 1 in turn, and let the lifting rope 2 pass through the corresponding hole groove on the detection component 4; when in use, turn on the air pump 5, record the rotation speed of the detection wheel 44 within a certain period of time, and record the specific detection process, the sliding component 3 is driven by the air pump 5 to move, so that the lifting rope 2 is pulled, and then the detection wheel 44 is rotated, and the surface of the detection wheel 44 is provided with axial anti-slip grooves, which can effectively rotate the detection wheel 44 during the pulling process of the lifting rope 2; the movement distance of the sliding component 3 is equal to the rotation speed of the detection wheel 44 per unit time (the movement distance of the sliding component 3 is the blockage position of the electrical bushing 1). It is worth mentioning that after the air pump 5 introduces gas into the electrical bushing 1, it can provide power for the movement of the sliding component 3 inside the electrical bushing 1. Due to the uneven internal space of the electrical bushing 1, in order to facilitate the operation of the sliding component 3, the sliding sleeve 30 can be squeezed to make the corrugated folding part 31 fold, thereby alleviating the squeezing of the sliding sleeve 30. A plug-in rod 32 is fixedly installed on the inner side of the sliding sleeve 30, which ensures the service life of the sliding sleeve 30 and is beneficial to the movement of the sliding component 3 inside the electrical bushing 1.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
