[0020] Spray water supply device for wiper equipment in driller's room, such as Figure 1-3As shown, it includes a tank body 1 and a shield 2 for supporting and protecting the tank body 1. The shield 2 is a rectangular hollow structure with a groove on one side wall and an open lower end. A plurality of support seats 3 for fixing and supporting the tank body 1 in the shield 2 are provided at the groove edges on both sides of the groove of the shield 2. The water inlet at the upper end of the tank body 1 is sealed and fixedly connected with a quick connector 9 located in the long groove at the top of the shield 2. The quick connector 9 is an externally purchased part and is not described here. A drain pipe 10 and two water outlet pipes 11 with controllable on / off are provided at the bottom of the tank body 1, and the two water outlet pipes 11 are respectively connected to the front windshield spray pipe and the top windshield spray pipe. The tank body 1 is connected to the positive pressure air through the air control device. The tank body 1 is connected to the air source, and the filling and exhaust control in the tank body 1 and the on-off control of the front windshield water spray pipe and the top windshield water spray pipe are realized under the control of the air control device; in the above structure, the tank body 1 used for supplying water to the front windshield water spray pipe and the top windshield water spray pipe is detachably supported and fixed by setting the shield 2, so as to provide conditions for the reliable installation of the tank body 1 on the driller's room; the positive pressure air source and the tank body 1 are connected through the air control device, and the filling and exhaust control in the tank body 1 and the on-off control of the front windshield water spray pipe and the top windshield water spray pipe are realized under the control of the air control device, so as to increase the spraying distance, improve the spraying effect, and meet the requirements of cleaning water for the front windshield and the top windshield;

[0021] like Figure 3As shown, the specific connection structure of the air control device is as follows: the air control device includes a shuttle valve 6, a two-position two-way air control valve 1 4, a two-position two-way air control valve 2 7 and a load relief valve 8. The two outlet pipes 11 are both equipped with a two-position two-way air control valve 1 4, and the two two-position two-way air control valves 1 4 are respectively connected to a front branch pipe 13 equipped with a front manual knob valve 12 and a top branch pipe 15 equipped with a top manual knob valve 14, wherein the two two-position two-way air control valves 1 4 are respectively in a normally closed state when the front manual knob valve 12 and the top manual knob valve 14 are not triggered, and the current When the manual knob valve 12 and the top manual knob valve 14 are triggered individually or simultaneously, the corresponding two two-position two-way air control valves 14 are opened, and the water in the tank body 1 can flow out; the front branch pipe 13 and the top branch pipe 15 are connected to the inflation pipe 16 connected to the positive pressure air source, and the unloading pipe at the upper end of the tank body 1 is installed with an unloading safety valve 8 connected to the shuttle valve 6 connected between the top branch pipe 15 and the front branch pipe 13; the two-position two-way air control valve 2 7 is installed on the overflow pipe on the side wall of the upper end of the tank body 1. When the manual knob valve 12 and the top manual knob valve 14 are triggered individually or simultaneously, the corresponding two two-position two-way air control valves 1 4 are opened, and the water in the tank body 1 can flow out; the front branch pipe 13 and the top branch pipe 15 are connected to the inflation pipe 16 connected to the positive pressure air source, and the unloading pipe at the upper end of the tank body 1 is installed with an unloading safety valve 8 connected to the shuttle valve 6 connected between the top branch pipe 15 and the front branch pipe 13; the two-position two-way air control valve 2 7 is installed on the overflow pipe on the side wall of the upper end of the tank body 1. When triggered at the same time, the shuttle valve 6 opens, and the positive pressure gas in the positive pressure gas source is pressed into the tank body 1 through the inflation pipe 16, the shuttle valve 6, and the unloading safety valve 8. At the same time, the water in the tank body 1 is connected to the corresponding water spray pipe for water spraying. Among them, after the front manual knob valve 12 and the top manual knob valve 14 are reset and closed, one of the interfaces of the front manual knob valve 12 and the top manual knob valve 14 that is connected to the atmosphere is connected to the shuttle valve 6, so that the tank body 1 is automatically depressurized. However, when the tank body 1 needs to be opened when the front manual knob valve 12 and the top manual knob valve 14 are closed, , the staff needs to manually control the unloading safety valve 8 to manually relieve the pressure to ensure the safety and reliability of the operation; the two-position two-way air control valve 27 in this scheme plays the role of an overflow valve. When water is injected into the tank body 1 under normal pressure, when the water level reaches the height of the overflow pipe, the excess water is discharged through the two-position two-way air control valve 27, that is, when the tank body 1 is injected with water, the two-position two-way air control valve 27 is in a normally open state; wherein, the shuttle valve 6 is arranged so that the inflation pipeline can be filled with positive pressure gas into the tank body 1 when the front manual knob valve 12 and the top manual knob valve 14 are activated separately or simultaneously;

[0022] Specifically, a pressure relief valve 5 connected to the inflation pipe 16 is provided on the top of the protective cover 2. The setting of the pressure relief valve 5 can ensure the safety and reliability of the inflation pipeline. Specifically, a ball valve 17 for controlling the on-off state of the sewage pipe 10 is installed on the sewage pipe 10. When the tank body 1 is not in use or when the inside of the tank body 1 needs to be cleaned, the water inside the tank body 1 can be discharged through the ball valve 17.

[0023] like Figure 1-2As shown, the specific structure of the support seat 3 is as follows: the support seat 3 is an integrated structure consisting of an L-shaped support plate and an arc plate fixed to the end of the L-shaped support plate, the L-shaped support plate is fixedly connected to the shield 2 by bolts, and the arc plate tank body 1 is welded and fixed.

[0024] When the front manual knob valve 12 is manually triggered, the positive pressure gas in the inflation pipe 16 is filled into the tank body 1 through the front manual knob valve 12, the shuttle valve 6, and the unloading safety valve 8. At the same time, the two-position two-way air control valve 14 corresponding to the front manual knob valve 12 is turned from the normally closed state to the open state to supply water to the front windshield spray pipe. After the front manual knob valve 12 rebounds and resets, the corresponding two-position two-way air control valve 14 is closed, and the front manual knob valve 12 automatically relieves the pressure in the tank body 1. When the top manual knob valve 14 is manually triggered, the positive pressure gas in the inflation pipe 16 is filled into the tank body 1. The positive-pressure gas is filled into the tank body 1 through the top manual knob valve 14, the shuttle valve 6 and the unloading safety valve 8. At the same time, the two-position two-way air control valve 14 corresponding to the top manual knob valve 14 is turned from the normally closed state to the open state to supply water to the top windshield spray pipe. When the top manual knob valve 14 rebounds and resets, the corresponding two-position two-way air control valve 14 is closed, and the top manual knob valve 14 automatically relieves the pressure in the tank body 1. Each time the quick connector 9 is opened, the unloading safety valve 8 needs to be manually controlled to manually relieve the pressure, and the quick connector 9 can be opened only after the manual pressure relief.

[0025] The technical solution has a simple structure, reasonable design, low cost, convenient and quick operation, and high use value.
