Technical Field
[0001] This utility model relates to a spraying device, and more particularly to a building wall maintenance spraying device. Background Technology
[0002] During the construction process, the exterior walls of buildings need to be regularly sprayed with water for moisture maintenance. Currently, manual spraying is mainly used to maintain the walls. After spraying water, the walls are kept moist for a certain period of time, thereby improving the overall strength of the walls when they dry and preventing cracking.
[0003] For example, Chinese Patent Publication No. CN220247675U discloses a spraying device for curing concrete walls, relating to the field of building construction technology. It includes a support plate, a water supply mechanism, and a spraying mechanism for spraying and curing concrete walls. The spraying mechanism is fixed above the support plate. The spraying mechanism includes a lifting assembly, a water supply pipe, a horizontal pipe, and nozzles. There are two water supply pipes symmetrically arranged on the left and right sides of the lifting assembly. The horizontal pipe is horizontally positioned in front of the lifting assembly and connected to the water supply mechanism via the water supply pipe. The nozzles are located in front of the horizontal pipe. The lifting assembly includes a fixed box, a servo motor, a lead screw, a lifting sleeve, a lifting rod, and a guide rod. This invention expands the spraying range of the device, making it suitable for concrete walls with considerable height, and effectively improving the device's performance.
[0004] The existing spraying device for curing concrete walls has some problems. First, the nozzles are fixed to the horizontal pipe, which makes them prone to clogging and damage after long-term use. They are not easy to replace individually, and replacing the entire horizontal pipe is quite expensive. Utility Model Content

[0019] 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.
[0020] Please see Figure 1-3 This utility model provides a technical solution: a building wall maintenance spraying device, including a carrying trolley 1, a water tank 101 fixedly connected to the carrying trolley 1, a pump fixedly connected inside the water tank 101, a Y-shaped delivery hose 3 connected to the output end of the pump, a stand 2 fixedly connected to the carrying trolley 1 near the front edge, a limiting groove 201 opened in the stand 2, a limiting slider 401 slidably installed in the limiting groove 201, a mounting base 4 fixedly connected to the front of the limiting slider 401, insertion holes 403 symmetrically opened in the mounting base 4, a support rod 406 inserted into the insertion hole 403, a connecting collar 5 sleeved on the support rod 406, and a spray head 503 fixedly connected to the front of the connecting collar 5.
[0021] In this embodiment, a certain amount of clean water is stored in the water tank 101. Starting the pump delivers the clean water to the Y-shaped delivery hose 3, which then delivers the clean water to the nozzle 503 for spraying the wall. The support rod 406 is inserted into the insertion hole 403. By adjusting the insertion depth of the support rod 406, the length of its extensions on both sides can be adjusted. Connecting collars 5 are fitted onto the support rod 406, and the nozzle 503 is then installed on the support rod 406. The number and spacing of the connecting collars 5 can be adjusted. The spacing ensures consistent spray density from the nozzles 503, allowing for effective wall spraying. The connecting collar 5 is directly fitted onto the support rod 406. If the nozzle 503 is damaged, the connecting collar 5, along with the nozzle 503, can be removed and replaced separately. When working indoors, the support rods 406 may interfere with the door frame in narrow spaces such as doorways. In this case, the support rods 406 can be pulled out from the insertion hole 403, reducing the overall width of the device and facilitating passage through narrow indoor spaces such as doorways.
[0022] To achieve the purpose of fixing the support rod 406 in the insertion hole 403, the device adopts the following technical solution: a threaded adjusting rod 202 is rotatably installed in the limiting slide groove 201, a power motor 203 is fixedly connected to the top of the stand 2, the output end of the power motor 203 is fixedly connected to the threaded adjusting rod 202, a threaded through hole 402 is opened in the limiting slide 401, the threaded through hole 402 is threadedly engaged with the threaded adjusting rod 202, and a first threaded sleeve block 404 is embedded on both the upper and lower surfaces of the mounting base 4, the first threaded sleeve block 404 is connected to the inside of the insertion hole 403, and a first fixing bolt 405 is threadedly installed in the first threaded sleeve block 404.
[0023] By starting the power motor 203, the threaded adjusting rod 202 can be rotated. The threaded adjusting rod 202 is threadedly engaged with the threaded through hole 402. The rotation of the threaded adjusting rod 202 can drive the limiting slider 401 to move. The movement of the limiting slider 401 can drive the mounting base 4 to move, thereby adjusting the height of the support rod 406 and the connecting collar 5. The movement of the connecting collar 5 will drive the spray head 503 to move, thereby performing spray maintenance operations on walls of different heights. The first threaded sleeve 404 is connected to the inside of the insertion hole 403. Tightening the first fixing bolt 405 will cause its end to contact the support rod 406, thereby using friction to fix the support rod 406 inside the insertion hole 403.
[0024] In order to fix the connecting collar 5 to the support rod 406, the device adopts the following technical solution: a second threaded sleeve block 501 is embedded on the connecting collar 5, a second fixing bolt 502 is installed on the inner thread of the second threaded sleeve block 501, a threaded connector 504 is fixedly connected to the bottom of the nozzle 503, and several quick connectors 301 are connected to the Y-shaped conveying hose 3, and the quick connectors 301 and the threaded connectors 504 cooperate with each other.
[0025] By tightening the second fixing bolt 502, the lower end of the second fixing bolt 502 will contact the support rod 406, and then the connecting collar 5 will be fixed on the support rod 406 by friction. The threaded connector 504 and the quick connector 301 cooperate with each other, and then the quick connector 301 can be used to pump clean water to the nozzle 503, and the nozzle 503 can be used to spray clean water onto the wall.
[0026] The working principle and usage process of this utility model are as follows: When in use, a certain amount of clean water needs to be added into the water tank 101. Start the power motor 203 to drive the threaded adjustment rod 202 to rotate. The rotation of the threaded adjustment rod 202 can drive the mounting base 4 to move. The movement of the mounting base 4 in turn drives the support rod 406 to move, and finally drives the nozzle 503 to move. After adjusting the nozzle 503 to a suitable height, start the pump to deliver clean water to the Y-type delivery hose 3, and then deliver it to the nozzle 503. The nozzle 503 can be used to spray water onto the wall. If a single nozzle 503 is damaged, the quick connector 301 connected to the threaded connector 504 can be unscrewed, and the second fixing bolt 502 can be loosened to release the fixing of the connecting collar 5. At this time, the connecting collar 5 can be directly removed and replaced individually.
[0027] 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 these 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.
