Description

Technical Field

[0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to a cleaning water gun. Background Art

[0002] Water supply tanks need to be installed in residential areas, office buildings, shopping malls and other places that require centralized water supply or peak water replenishment. Most of the existing water tanks are made of stainless steel. In order to ensure the stability of the tank structure after the water is stored in the tank, several criss-crossing reinforcements are welded inside the tank. According to the provisions of the drinking water hygiene standard GB 5749, the water tank needs to be disinfected and cleaned regularly. The current common practice is that the cleaning staff carries tools into the water tank to clean the water tank, and the problems caused by this are also obvious: (1) Due to the limited space of the water tank and the reinforcement blocking the inside, it is inconvenient and unsafe for personnel to enter and exit, the operation preparation time is long, and labor protection supplies are many. Special personnel must be arranged outside the water tank to watch and cooperate; (2) Due to the uncertainty of manual operation, it is difficult to supervise the cleaning quality; (3) There is a risk of secondary pollution due to foreign objects entering the water tank. Summary of the invention

[0003] The purpose of the present invention is to provide a water tank omnidirectional controllable automatic cleaning water gun installed inside the water tank to overcome the above problems.

[0004] To achieve the above object, the present invention is implemented through the following technical solutions.

[0005] A driving device for cleaning a water gun comprises a bracket, a power source, a transmission sleeve and a thread sleeve; the transmission sleeve is tubular and has a keyway inside; the power source drives the transmission sleeve to rotate axially, the transmission sleeve is movably connected to the bracket through a bearing sleeve, the thread sleeve is connected to the bracket, and the thread sleeve is coaxial with the transmission sleeve.

[0006] Furthermore, the power source is a motor, which is fixedly connected to the bracket, and the motor drives the transmission sleeve to rotate. The power source can be in various forms, such as electric or pneumatic, and ordinary motors are preferred, which have various models, high quality, low price, and convenient purchase; the transmission method between the motor and the transmission sleeve can be gear transmission, worm gear transmission, belt or chain transmission, rack and pinion transmission, etc.

[0007] A cleaning water gun is further provided, comprising a water gun tube and a driving device; the water gun tube is composed of an inner tube and an outer tube, the outer wall of the inner tube is provided with a thread, and the outer wall of the inner tube is provided with an axial key; the driving device comprises a bracket, a power source, a transmission sleeve, and a thread sleeve; the motor, the thread sleeve and the bracket are fixedly installed, and the transmission sleeve is movably connected to the bracket through a bearing sleeve; the transmission sleeve is tubular, the inner diameter of the transmission sleeve matches the outer diameter of the inner tube, the power source drives the transmission sleeve to rotate axially, a keyway is provided on the inner side of the transmission sleeve, the axial key and the keyway are slidably matched, the thread sleeve and the thread of the outer wall of the inner tube are matched, and the bottom of the transmission sleeve is fixedly connected to the upper end of the outer tube. The connection method between the transmission sleeve and the outer tube can be threaded connection, snap connection, pin connection or welding, the transmission sleeve drives the inner tube and the outer tube to rotate at the same speed, the thread outside the inner tube rotates in the thread sleeve to generate a force for moving up and down, so that the inner tube moves up and down along the axial direction, and the key slides up and down in the keyway.

[0008] Furthermore, the inner tube is coaxial with the outer tube, the length of the outer tube is shorter than the length of the inner tube, and both ends of the inner tube are located outside the outer tube.

[0009] It further includes a nozzle and a connecting rod; the upper end of the inner tube is connected to a water source, and the lower end of the inner tube is connected to a transverse tube, which is perpendicular to the inner tube; the bottom of the nozzle is movably connected to the transverse tube, the top of the nozzle is a water spray port, and the nozzle rotates with the axis of the transverse tube as the rotation axis; one end of the connecting rod is movably connected to the outer tube, and the other end of the connecting rod is movably connected to the nozzle. The power source drives the transmission sleeve to rotate, and the transmission sleeve drives the inner tube and the outer tube to rotate at the same speed. While the inner tube rotates, the inner tube moves up and down along the axial direction through the threaded action of the thread sleeve and the outer wall of the inner tube. The key on the inner tube slides up and down in the keyway of the transmission sleeve, and the outer tube remains fixed in the axial direction. Under the push-pull action of the connecting rod, the nozzle rotates along the axial direction of the transverse tube, so that the water flow maintains a vertical circular motion trajectory; the inner tube and the outer tube rotate at the same speed, driving the nozzle to rotate along the axial direction of the water gun tube, so that the water flow maintains a horizontal circular motion trajectory, thereby combining the water flow to clean the water tank in an all-round and dead-angle-free manner. The up and down movement and left and right rotation movement of the inner tube are completed by setting the forward and reverse rotation time or number of turns of the power source driving the transmission sleeve.

[0010] Furthermore, a ring sleeve is provided outside the inner tube, and upper and lower limit devices matching the ring sleeve are provided on both sides of the ring sleeve along the axial direction of the inner tube. The ring sleeve is connected to the inner tube by threads or welded on the inner tube, and the upper and lower limit devices control the power source to drive the transmission sleeve forward, reverse or stop. Setting the forward and reverse time or number of turns of the power source driving the transmission sleeve requires a complex control system, and determining its parameters is relatively cumbersome. Using a limiter for control is convenient to control.

[0011] Furthermore, a sliding rod parallel to the inner tube is provided beside the inner tube, a slider is provided on the sliding rod, a groove is provided on one side of the slider, the groove matches the ring sleeve, a touch rod is provided on the other side of the slider, and the touch rod matches the upper and lower limit devices. If only the ring sleeve is used to touch the limiter, the diameter of the ring sleeve needs to be larger, which is not conducive to the installation of the water gun tube and the placement of other equipment. By adding the sliding rod and the slider, the diameter of the ring sleeve is reduced.

[0012] Furthermore, the inner tube and the transverse tube are in a T-shape, and a nozzle is installed at each end of the transverse tube. Compared with the L-shaped tube, one nozzle can be added to enhance the cleaning effect.

[0013] Furthermore, the angle between the two nozzles is any angle. When the angle between the two nozzles is zero, the flushing effect of a relatively small area can be enhanced, but the nozzles have a large water pressure and a high flow rate, which has a large reaction force on the water gun tube, and the transmission sleeve is prone to eccentric wear after long-term use; when the angle between the two nozzles is 180 degrees, the reaction force of the water flow on the water gun tube can be basically eliminated, and the service life of the transmission sleeve can be extended.

[0014] Beneficial effects: Compared with the prior art, the advantages of the present invention are:

[0015] 1) Replace manual cleaning to achieve fully automatic operation, safe and hygienic to use, without the risk of secondary pollution;

[0016] 2) The nozzle can move in all directions without any dead corners;

[0017] 3) The equipment has a compact structure, is easy to install and maintain, and has a long service life. BRIEF DESCRIPTION OF THE DRAWINGS
