Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 As shown, a continuous underground wall scrubber includes a housing 1, a connecting plate 2, steel teeth 3, and a scraper 4.

[0026] like Figure 1 As shown, the outer casing 1 is rectangular, and its width is adapted to the width of the groove formed by the floor ties. The outer casing 1 includes a base plate 11, a top plate 12, and a pair of side plates 13. The base plate 11 and the top plate 12 are horizontally arranged, and their dimensions are 530mm in length, 530mm in width, and 20mm in thickness, respectively. The pair of side plates 13 are vertically arranged on both sides of the base plate 11 and the top plate 12, and their dimensions are 450mm in length, 440mm in width, and 20mm in thickness, respectively.

[0027] like Figure 1 As shown, a counterweight plate 14 is vertically arranged between the bottom plate 11 and the top plate 12. The counterweight plate 14 is located between a pair of side plates 13 to increase the weight of the wall brush and ensure that the wall brush can stably clean the mud and mud skin and other impurities at the joint of adjacent tank sections.

[0028] like Figure 1 As shown, the connecting plate 2 is vertically positioned at the center of the upper surface of the top plate 12. The dimensions of the connecting plate 2 are: length 500mm, width 250mm, and thickness 20mm. The connecting plate 2 has a 60mm diameter connecting hole on the non-connecting side for connecting the grab bucket.

[0029] like Figure 1 As shown, steel teeth 3 are horizontally and spaced apart on the lower end face of one end of the base plate 11, and scrapers 4 are horizontally arranged on the lower end faces of multiple steel teeth 3. The steel teeth 3 are 250mm long, and the scrapers 4 are 530mm long, 80mm wide, and 20mm thick.

[0030] Before the wall brushing operation, the connecting plate 2 is inserted into the groove of the trenching machine grab, and the HRB400E steel is passed through the connecting hole to be tightly fixed with the trenching machine grab. During the wall brushing operation, the trenching machine grab is in an open state, the trenching machine grab is lowered, and the steel teeth 3 and the scraper 4 are attached to the surface of the I-steel joint under the self-weight of the wall brusher. Through the up-down reciprocating motion, the joint of the slot section is washed, so that the dirt and other impurities at the joint are removed, the connection quality between adjacent slot sections of the underground continuous wall is ensured, and problems such as leakage are prevented.

[0031] Meanwhile, by setting the wall brusher which can be quickly connected and used, the cleaning operation on the surface of the joint of the slot section can be quickly performed, a large area of cleaning work can be completed in a short time, the construction time is reduced, the construction progress of the whole underground continuous wall is accelerated, and the construction efficiency is improved due to the simple structure and light weight, facilitating transportation and installation on the construction site

[0032] And by setting the wall brusher with high stability, the cleaning quality can be ensured to be uneven due to the difference in operation of workers during manual cleaning, and each joint of the slot section can be cleaned according to the specified quality standard.

[0033] As shown in Figure 1 , Figure 2 , one side of the scraper 4 is used for scraping cleaning, and the other side is provided with a steel wire brush 41. An installation rod 42 is vertically arranged on the scraper 4, an installation hole 31 is arranged on the steel tooth 3 for the installation rod 42 to penetrate, and a locking mechanism 5 is arranged on the steel tooth 3 for fixing the installation rod 42.

[0034] As shown in Figure 1 , Figure 2 , the locking mechanism 5 includes a locking seat 51, a locking rod 52 and a screw rod 53. The locking seat 51 is vertically arranged on the steel tooth 3, and the locking rod 52 is horizontally and slidingly connected to the steel tooth 3 and located between the locking seat 51 and the installation rod 42.

[0035] As shown in Figure 1 , Figure 2 , the installation rod 42 is provided with a locking hole 54 for the locking rod 52 to penetrate, and the end of the locking rod 52 for penetrating the locking hole 54 is provided with a guide inclined surface 55. The screw rod 53 is horizontally and threadedly connected to the locking seat 51 and rotationally connected to the locking rod 52.

[0036] When the dirt is cleaned, the side of the scraper 4 with the steel wire brush 41 is inward, the scraper 4 is used for scraping the joint of the slot section, when the dirt is cleaned, the screw rod 53 is controlled to rotate, the screw rod 53 drives the locking rod 52 to gradually separate from the locking hole 54, and the locking rod 52 is removed. Then the scraper 4 can be removed from the steel tooth 3, and the free disassembly of the scraper 4 is completed.

[0037] Then, the scraper 4 is rotated so that the side with the wire brush 41 faces outwards. The screw 53 is then rotated back to its original position, causing it to gradually insert and pass through the locking hole 54, thus installing the locking rod 52 and fixing the scraper 4. Subsequently, when the wall scrubber is working, the wire brush 41 can be used to scrub the joints of the groove section, ensuring the cleanliness of the cleaning area.

[0038] like Figure 1 , Figure 2 As shown, a protective cover 6 covering the locking mechanism 5 is provided on the steel tooth 3. A switch cover 61 is rotatably connected to one end of the protective cover 6 near the locking seat 51. A hook 62 is provided on the switch cover 61 to hook the protective cover 6.

[0039] Therefore, by setting a protective cover 6 that is easy to open and close, the locking mechanism 5 can be locked and released, and the locking mechanism 5 can be protected to prevent debris from contaminating the locking mechanism 5, making the operation of the locking mechanism 5 more convenient.

[0040] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
