Technical Field

[0001] The present invention relates to the technical field of fire detection, and particularly to a cleaning device for a marine flame detector. Background Art

[0002] A flame detector detects that when a substance burns, while generating smoke and releasing heat, it also generates visible or invisible light radiation that does not exist in the atmosphere. The main reason for using a flame detector at sea is to improve the safety performance of ships and offshore platforms and prevent the occurrence and spread of fires.

[0003] After retrieval, in the prior art (publication number: CN115931138A), there is a flame detector housing, which is proposed in the text that "it includes a barrel base; the barrel base includes a barrel body, and flange rings are integrally formed at both ends of the barrel body; two compartments are formed inside the barrel body through an integrally formed partition; a wire post communicating with one compartment is integrally formed on the outer wall of the barrel base; inner convex rings are arranged on both sides of the partition inside the barrel body; internal threads are arranged inside the inner convex rings; a plurality of threaded blind holes are respectively arranged on both sides of the partition; the threaded blind holes on both sides are arranged in a staggered manner; a through hole is formed in the partition; the partition serves as both an isolation plate of the barrel body to form two compartments and a support body for the entire structure, ensuring the overall structural strength of the barrel body;".

A plurality of tooth grooves are opened on the periphery of the activity frame. A connecting rod is welded on the outer wall of the activity frame, and support rods are screwed at both ends of the bottom of the connecting rod. Below the bottom of the connecting rod there is a support rod, and one end of the bottom of the support rod is screwed and fixed to the top of the support rod. A scraping plate is screwed on the bottom end face of the support rod, and a second sponge block is adhesively bonded on the outer wall of the scraping plate.

[0007] Preferably, the scraping plate is made of rubber material, the first sponge block and the second sponge block are both PVA cleaning sponges, and the teeth of the gear mesh with the tooth grooves.

[0008] Preferably, brackets are welded on the four circumferences of the inner wall of the cleaning frame, and dampers are screwed on the brackets. The telescopic end of the damper is screwed with a support pad, and the support pad is attached to the outer wall of the motor.

[0009] Preferably, side plates are welded on the outer walls on both sides of the bracket, and rubber columns are adhesively bonded on the side plates. One end of the bottom of the rubber column is adhesively bonded and fixed to the top end face of the support pad.

[0010] Preferably, a ventilation opening is opened on the outer wall of the other end of the cleaning frame, and a blower is screwed outside the ventilation opening. A top cover is arranged above the top of the blower, and the top cover is welded and fixed to the outer wall of the cleaning frame. A power supply is screwed below the bottom of the blower, a bottom plate is welded below the bottom of the power supply, and a controller is screwed on the bottom end face of the bottom plate.

[0011] Preferably, a lifting frame is arranged below the bottom of the cleaning frame.

Lifting grooves are opened on the inner walls on both sides of the lifting frame, and a lifting block is slidably installed between the two lifting grooves. The top of the lifting block is welded and fixed to the bottom end of the lifting column, and a handle is welded on the outer wall of the lifting block.

[0012] Preferably, handrails are screwed on the outer walls on both sides of the lifting frame.

A pressing plate is welded on the bottom end face of the lifting frame.

[0013] Preferably, a number of drain holes are equidistantly formed in the bottom of the cleaning frame. A drain pipe is welded to the bottom of the cleaning frame, and the drain holes are located inside the drain pipe.

[0014] Compared with the prior art, the present invention provides a cleaning device for a marine flame detector, which has the following beneficial effects: 1. In the present invention, the cleaning frame is sleeved on the detection end of the flame detector, and the first sponge block is attached to the detection end of the flame detector. The spring telescopic rod can improve the connection tightness between the first sponge block and the flame detector. The motor drives the insertion tube, so that the spring telescopic rod drives the support plate to rotate. Under the transmission of the support plate, the first sponge block can rotate. The rotation of the first sponge block can clean the detection end of the flame detector. When the motor rotates, the first pulley drives the second pulley to rotate through the transmission belt, and then the transmission rod rotates synchronously. The gear and the tooth groove are engaged to drive the movable frame to rotate when the transmission rod rotates. The connecting rod drives the scraper and the second sponge block to rotate. The second sponge block can wipe the outer wall of the flame detector. The scraper can scrape the residual water on the outer wall of the flame detector after the second sponge block wipes, improving the cleaning effect. The support rod can increase the fitting effect between the scraper and the flame detector. This method can clean the residual water on the flame detector, prevent seawater from adhering to the flame detector for a long time, damage the flame detector, ensure the sensitivity of the flame detector, and prevent false alarms and missed alarms.

[0015] 2. The damper, the support pad and the rubber column can play a role in shock absorption and buffering when the motor is driven. The blower can blow air into the cleaning frame from the ventilation port. The air passes through the cleaning frame and blows towards the flame detector, which is beneficial to the rapid drying of the flame detector. The top cover can block the blower to play a protective role. The power supply can supply power to the motor and the blower. The controller is used to control electrical equipment. By pulling the handle and lifting it upwards, the lifting block can slide in the lifting groove, and then the lifting column jacks up the cleaning frame to lift its height, so as to clean the flame detectors at different height positions. Inserting the plug rod into the positioning hole can fix the position of the lifting column. Stepping on the pressing plate and holding the handrails with both hands can increase the stability of the lifting frame. The water in the cleaning frame can be discharged out through the drain holes, and the drain pipe can limit the direction of water discharge to avoid splashing water on the staff below.
