Fixed alarms are installed in underground wells, pits, and underground tanks below the reference ground. However, underground places have serious water accumulation, and gas detectors are often submerged, resulting in the scrapping of alarms, causing economic losses, and the failure of safety warning functions, which bury safety production risks. Summary of the invention
[0003] The purpose of the utility model is to overcome the shortcomings of the existing fixed gas alarm installation technology and to provide a pit alarm waterproof anchoring direct navigation lifting device which has a smart design, simple structure, strong practicality and high reliability.
[0004] The purpose of this utility model is achieved through the following technical solutions:
[0005] The utility model is a pit alarm waterproof anchor direct navigation lifting device, which is characterized by comprising a guide rod base, a guide rod arranged on the guide rod base, a guide groove slidably connected along the guide rod, two floating ship balls arranged on the guide groove, and a gas detection alarm arranged on the guide groove.
[0006] The two floating ship spheres are symmetrically arranged along the guide groove.
[0007] Lubricating grease is provided between the guide rod and the guide groove.
[0008] The two floating spheres are made of stainless steel, and the guide rods and guide grooves are made of galvanized steel pipes.
[0009] Advantages of the utility model:
[0010] The utility model discloses a waterproof and floodproof anchored direct-flight lifting device for a pit alarm, which adopts a stainless steel float and fixing accessories, and a direct-flight guide rod and a guide groove adopt a galvanized steel pipe, which prevents the lifting device from corrosion, prolongs its service life, and ensures continuous safe production. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0012] The specific implementation of the present utility model is further described below in conjunction with the accompanying drawings.
[0013] like Figure 1 As shown, the utility model of the pit alarm waterproof anchoring direct navigation lifting device is characterized by including a guide rod base 1, a guide rod 5 arranged on the guide rod base 1, a guide groove 3 slidingly connected along the guide rod 5, two floating ship balls 2 arranged on the guide groove 3, and a gas detection alarm 4 arranged on the guide groove 3.
[0014] The two floating spheres 2 are symmetrically arranged along the guide groove 3 .
[0015] Lubricating grease is provided between the guide rod 5 and the guide groove 3 .
[0016] The two floating spheres 2 are made of stainless steel, and the guide rods 5 and guide grooves 3 are made of galvanized steel pipes.
[0017] Implementation method:
[0018] Combine the following Figure 1 The utility model is further described in detail through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the utility model cannot be limited by them. The pit alarm anti-flooding anchor direct navigation lifting device includes a guide rod base 1, two floating ball bodies 2, a guide groove 3, a gas detection alarm 4, and a guide rod 5.
[0019] The floating boat lifting guide groove 3 adopts a stainless steel pipe with a diameter of 50mm and a length of 500mm, which meets the installation height of the combustible gas alarm. The fixed guide rod 5 adopts a stainless steel pipe with a diameter of 40mm and a length of 1500mm. The guide groove 3 and the guide rod 5 have a moderate clearance. The gap is filled with a horizontal motion rolling guide bearing and is lubricated. The bottom plate of the guide rod base 1 is fixed with expansion bolts. The floating boat bracket adopts 40mm×40mm stainless steel angle steel, two 900mm length angle steels on the horizontal frame, and 8mm×50mm floating ball fulcrum fixing grooves on the side. Four 400mm length angle steels in the longitudinal direction separate two 400mm×400mm square spaces for installing the floating ball, and argon arc welding is used to ensure the stability and strength of the frame. The two middle angle steels are 100mm apart and argon arc welded to the outer wall of the bottom end of the guide groove to ensure that the guide groove 3 can fit smoothly with the guide rod 5. The two floating spheres 2 are stainless steel hollow sealed spheres with a diameter of 300mm and a thickness of 1.5mm. The center line of the sphere is symmetrically argon arc welded, prefabricated with a diameter of 10mm, a length of 50mm, and a terminal buckle M8 metric thread stainless steel fulcrum. It can be flexibly installed and disassembled with the floating bracket fixing groove, and is fastened with anti-stripping nuts. The floating bracket fixing groove uses 40mm×40mm stainless steel angle steel with a 5mm length adjustable gap to ensure the parallel symmetry of the center lines of the two floating balls and the vertical center of gravity of the floating machine, and the lateral force is balanced. The buoyancy of the ball is calculated by F=4 / 3×πR 3×ρThe overall buoyancy of the two floats is 29 kg. The floating ship's direct navigation lifting components include floats, floating ship frames, gas alarms and installation accessories, weighing 12 kg. The difference in gravity and buoyancy is just enough to make the sphere half immersed in liquid, symmetrical and stable. During operation, the gas detection alarm 4, with the floating ship's direct navigation and lifting, the electrical connection method of its power supply cable and signal transmission cable cannot produce blocking force on the direct navigation and lifting, and has a sufficiently long telescopic and extension margin. It adopts a 1000mm flexible explosion-proof connecting pipe with toughness and curvature, which can move the gas alarm freely and unhindered, eliminate the lateral force of the floating ship's direct navigation and lifting movement, reduce the friction between the lifting guide groove 3 and the guide rod 5, ensure the freedom of the floating ship and the liquid surface to rise and fall with the waves, and meet the waterproof and explosion-proof specifications and technical standards of the gas alarm.
[0020] The utility model of the waterproof and flood-proof anchored direct-flight lifting device for the pit alarm adopts a stainless steel float and fixing accessories, and the direct-flight guide rod 5 and the guide groove 3 adopt galvanized steel pipes, which prevents the lifting device from corrosion, prolongs its service life, and ensures continuous safe production.
