Description
Technical Field
[0001] This utility model relates to a protective device for instruments used in thermal control of power plants, belonging to the field of instrument protection technology. Background Technology
[0002] Measurement is the eye of industrial production. A flow meter is an instrument used to indicate the flow rate or the total amount of fluid within a selected time interval. Simply put, it is an instrument used to measure the flow rate of fluid in pipes or open channels. Flow measurement is a component of metrology science and technology, and it is widely used in the petrochemical industry. In current technology, flow meters are mostly used in outdoor environments, and damage to flow meters is mostly caused by external forces. However, existing flow meters lack protective devices and are prone to damage, which greatly increases production costs. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a protective device for instruments used in thermal control of power plants, which is easy to install, protects the instruments, and reduces production costs.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a protective device for instruments used in power plant thermal control, comprising a fixed half-ring unit and a rotating half-ring unit. A protective cover is provided on the top of the fixed half-ring unit, and the protective cover is fitted onto the instrument. One end of the fixed half-ring unit and one end of the rotating half-ring unit are hinged together. A slot is provided at the other end of the fixed half-ring unit, and a plug is provided at the other end of the rotating half-ring unit. The slot matches the plug. A socket is provided on the plug. A movable insert is provided on the fixed half-ring unit. The rotating half-ring unit rotates around the hinge point, so that the other end of the rotating half-ring unit moves away from the other end of the fixed half-ring unit and is in an open state, or so that the other end of the rotating half-ring unit moves closer to the other end of the fixed half-ring unit, driving the plug to be inserted into the slot, and then the movable insert is inserted into the socket, thereby fixing the rotating half-ring unit and the fixed half-ring unit to the pipeline.
[0005] The fixed semi-ring unit includes two parallel fixed semi-rings, the protective cover is fixed to the top of the two fixed semi-rings, and slots are respectively opened at the other end of the fixed semi-rings.
[0006] The rotating semi-ring unit includes two parallel rotating semi-rings, one end of which is hinged to the fixed semi-ring, and the other end of which is respectively provided with a plug.
[0007] The movable insert includes a hollow sleeve horizontally positioned between two fixed semi-rings. A baffle is located at the center of the hollow sleeve's inner cavity. A rod and a spring are respectively positioned on either side of the baffle. One end of the rod protrudes from the hollow sleeve, and each rod corresponds to a slot. The other end of the rod is fixedly connected to one end of the spring, which is fixed to the baffle. A lever is symmetrically inserted through the hollow sleeve, with one end fixedly connected to the rod and the other end protruding from the hollow sleeve. Moving the lever towards the baffle moves the rod into the hollow sleeve's inner cavity, compressing the spring and placing the insert in the slot. Releasing the lever releases the spring's pressure, causing the rod to move outward and be inserted into the socket.
[0008] Nuts are respectively provided on the outer side of the rotating half ring, and screws are respectively screwed into the nuts. The screws pass through the rotating half ring, so that both ends of the screws protrude from the rotating half ring. A knob is fixed at one end of the screw, and a pressing plate is provided at the other end of the screw. Rotating the knob causes the screw to rotate and move inside the nut, so that the pressing plate approaches and abuts against the lower part of the pipe.
[0009] The extrusion plate has an arc-shaped structure, and the arc of the extrusion plate matches that of the pipe.
[0010] Compared with existing technologies, the advantages of this utility model are as follows: A protective device for instruments used in power plant thermal control, wherein the protective sleeve is fitted onto the instrument, and rotating the rotating half-ring causes its insert to be inserted into the slot. Releasing the lever causes the insert rod to be inserted into the socket under the action of a spring, thus fixing the rotating half-ring and the fixed half-ring onto the pipeline, achieving secure installation of the protective sleeve. Simultaneously, rotating the knob can move the lead screw within the nut, causing the compression plate to press against the lower part of the pipeline, preventing swaying and improving safety.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1 , 2 As shown in this embodiment, a protective device for instruments used in power plant thermal control includes a fixed half-ring unit and a rotating half-ring unit. A protective sleeve 1 is provided on the top of the fixed half-ring unit, which is fitted onto the instrument to protect it. One end of the fixed half-ring unit and one end of the rotating half-ring unit are hinged together by a pin. A slot 3 is provided at the other end of the fixed half-ring unit, and a plug 10 is provided at the other end of the rotating half-ring unit, which matches the slot 3. A socket 11 is provided on the plug 10, and a movable insert is provided on the fixed half-ring unit. When the rotating half-ring unit rotates around the hinge point, the other end of the rotating half-ring unit moves away from the other end of the fixed half-ring unit, opening up for easy placement on a pipe. Subsequently, the other end of the rotating half-ring unit moves closer to the other end of the fixed half-ring unit, causing the plug to be inserted into the slot, closing the slot and forming an annular cavity, so that the rotating and fixed half-rings surround the outer circumference of the pipe. Moving the movable insert allows it to be inserted into the socket, thus fixing the other end of the rotating half-ring unit to the other end of the fixed half-ring unit. During disassembly, reverse the movement of the movable plug to move it out of the socket, thus separating the other end of the rotating half-ring unit from the other end of the fixed half-ring unit.
[0017] The fixed semi-ring unit includes two parallel fixed semi-rings 2, with a protective cover 1 fixed to the top of each of the two fixed semi-rings 2. Slots 3 are respectively opened at the other end of each fixed semi-ring 2. The movable insert includes a hollow sleeve 12, which is horizontally positioned between the two fixed semi-rings 2. A vertically arranged baffle is located at the center of the inner cavity of the hollow sleeve 12, and horizontally arranged springs 14 are symmetrically arranged on both sides of the baffle. Horizontally arranged insertion rods 15 are symmetrically arranged within the inner cavity of the hollow sleeve 12. One end of each insertion rod 15 protrudes from the hollow sleeve 12 and corresponds one-to-one with a slot 3; the other end of each insertion rod 15 is fixedly connected to one end of a spring 14, and the other end of the spring is fixed to the baffle. A toggle rod 13 is symmetrically inserted through the hollow sleeve, perpendicular to the insertion rod 15. One end of the toggle rod is fixedly connected to the insertion rod, and the other end protrudes from the hollow sleeve. When the lever is moved toward the baffle, the insert rod moves toward the inner cavity of the hollow sleeve, the spring is compressed, making it easier for the insert block to be placed in the slot. Then the lever is released, the spring releases the pressure, and the insert rod moves outward, so that the insert rod is inserted into the socket.
[0018] like Figure 3 As shown, the rotating semi-ring unit includes two parallel rotating semi-rings 5, with insert blocks at the other end of each. Nuts 7 are respectively installed on the outer side of the rotating semi-rings, and horizontally arranged lead screws 9 are screwed into the nuts 7. One end of the lead screw 9 passes through the rotating semi-ring 5, so that both ends of the lead screw protrude from the rotating semi-ring. A knob 8 is fixed to one end of the lead screw, and a pressing plate 6 is installed at the other end of the lead screw. Rotating the knob causes the lead screw to rotate and move within the nut, so that the pressing plate approaches and abuts against the lower part of the pipe to prevent shaking.
[0019] The extrusion plate described above has an arc-shaped structure, and the curvature of the extrusion plate matches that of the pipe.
[0020] Place the protective sleeve on the instrument, rotate the half-ring to insert the insert into the slot, release the lever, and the spring will cause the insert rod to insert into the socket, thus fixing the rotating half-ring and the fixed half-ring to the pipeline, achieving a secure installation of the protective sleeve. Simultaneously, rotating the knob will move the screw within the nut, causing the clamping plate to press against the lower part of the pipeline, preventing wobbling and improving safety.
[0021] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
