DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] As described in the background technology, the existing platinum resistance thermometers are mainly used in the two temperature collection points of the heat meter integrator in the heat meter when actually used. Since these two temperature measurement points play a decisive role in the process of heat collection and calculation, the platinum resistance thermometer must be avoided from being accidentally touched or pulled out when in use to ensure the accuracy of the measurement results. For this purpose, this embodiment provides a platinum resistance protection device with high protection.

[0022] See also Figures 1 to 5 This embodiment proposes a highly protective platinum resistance protection device, including a pipeline 1, a protection mechanism 2 is arranged above the pipeline 1, the protection mechanism 2 includes a platinum resistance thermometer body 201 and a protection shell 202, and the platinum resistance thermometer body 201 is installed on the outer surface of the pipeline 1.

[0023] The platinum resistance thermometer body 201 is installed on the pipeline 1. The platinum resistance thermometer body 201 can detect the temperature of the conveying medium in the pipeline 1, and transmit the detection data to an external data receiving device through a wire for storage and recording.

[0024] A threading hole 10 is provided on the bottom surface of the protective shell 202 , through which a wire for data transmission between the platinum resistance thermometer body 201 and the outside world can pass conveniently.

[0025] A plurality of heat dissipation holes 9 are provided on the upper surface of the protective shell 202, and the plurality of heat dissipation holes 9 are evenly distributed on the upper surface of the platinum resistance thermometer body 201. The heat dissipation holes 9 can improve the air permeability and heat dissipation performance of the protective shell 202 so that the platinum resistance thermometer inside it will not be damaged due to excessive temperature.

[0026] The protective shell 202 fits the pipeline 1, and the outer surface of the protective shell 202 is fixedly connected with a first fixing belt 208, a second fixing belt 209 and two support rods 203. The first fixing belt 208 and the second fixing belt 209 are adapted to each other, and the inner wall of each support rod 203 is slidably connected with a first sliding rod 204, and the outer surfaces of the two first sliding rods 204 are fixedly connected with a first arc plate 205 and a connecting plate 206.

[0027] The protective shell 202 is attached to the outer surface of the pipeline 1 and is located directly above the platinum resistance thermometer body 201, so as to protect the platinum resistance thermometer body 201. The two support rods 203 are symmetrically fixed to the outer surface of the protective shell 202. Pulling the connecting plate 206 can drive the first sliding rod 204 to slide in the inner wall of the support rod 203, and the first sliding rod 204 drives the first arc plate 205 to move.

[0028] The inner wall of the first curved plate 205 can fit with the outer surface of the pipe 1, and the inner wall of the first curved plate 205 is provided with anti-slip grooves, which can increase the friction when the first curved plate 205 contacts the pipe 1, thereby improving the stability of the protective shell 202 when it is limited and fixed. At the same time, the first curved plate 205 is provided with a reserved groove adapted to the first fixing belt 208 and the second fixing belt 209.

[0029] See also Figure 5It can be seen that the first fixing belt 208 and the second fixing belt 209 are compatible and can be combined into a common clamp on the market. The structure thereof is not described in detail. The clamp can be tightened and loosened by turning the bolts thereon, thereby achieving limited fixation of the position of the protective shell 202 connected thereto.

[0030] The utility model further optimizes the clamp, and a first connecting block driving the through hole is fixed at the bolt on the clamp, and the bolt can be driven to rotate by rotating the connecting block. A slidable ring is sleeved on the outer surface of the second fixing belt 209, and a second connecting block with a through hole is fixed on the ring.

[0031] The user can pass the lock through the through holes on the first connecting block and the second connecting block to achieve connection between the two, thereby limiting the first connecting block so that the first connecting block cannot rotate, that is, the bolt cannot rotate, thereby protecting the protective shell 202 and preventing theft.

[0032] The inner walls of the two support rods 203 are slidably connected to two guide rods 3, which are fixedly connected to the first curved plate 205, and fixedly connected to the connecting plate 206. The guide rods 3 can be used to guide the movement of the first curved plate 205, so that the first curved plate 205 is more stable during movement.

[0033] A first spring 207 is sleeved on the outer surface of each first sliding rod 204 , and the support rod 203 and the first arc-shaped plate 205 are fixedly connected to the first spring 207 .

[0034] After the first curved plate 205 moves, it compresses the first spring 207, causing it to undergo elastic deformation. When the first curved plate 205 fits against the pipe 1 in the utility model, the first spring 207 is in a compressed state. Under the resetting action of the first spring 207, the first spring 207 tends to expand outward, causing the first curved plate 205 to fit closely against the pipe 1.

[0035] Two fixed blocks 4 are fixedly connected to the outer surface of the pipeline 1, and the inner walls of the two fixed blocks 4 are slidably connected to the second sliding rods 5. The ends of the two second sliding rods 5 that are close to each other are fixedly connected to the second arc plate 6, and the ends of the two second sliding rods 5 that are away from each other are fixedly connected to the fixed plate 7. The two second arc plates 6 are slidably connected to the protective shell 202.

[0036] The outer surface of the protective shell 202 is provided with a reserved groove adapted to the second arc plate 6. Pulling the two fixed plates 7 in reverse can drive the second slide bar 5 to slide in the inner wall of the fixed block 4, and the second slide bar 5 drives the second arc plate 6 to gradually slide out of the reserved groove opened on the protective shell 202.

[0037] The outer surfaces of the two second sliding rods 5 are both sleeved with second springs 8, and the fixing block 4 and the second arc plate 6 are both fixedly connected to the second springs 8. After the second arc plate 6 moves, it will compress the second spring 8, causing it to produce elastic deformation, until the two second arc plates 6 slide out of the reserved grooves opened on the protective shell 202, and the limiting fixation of the protective shell 202 can be released.

[0038] Working principle: When using the highly protective platinum resistance protection device, the first fixing belt 208 and the second fixing belt 209 are wound around the pipe 1 for one week and gradually tightened to achieve the initial limit fixation of the protective shell 202, and then the two connecting plates 206 are pulled in the opposite direction to drive the first slide bar 204 to slide in the inner wall of the support rod 203, and the first slide bar 204 drives the first curved plate 205 to move. After the first curved plate 205 moves, it compresses the first spring 207 to cause it to produce elastic deformation until the two The spacing between the first curved plates 205 is greater than the outer diameter of the pipe 1, and then the protective shell 202 is sleeved on the platinum resistance thermometer body 201 and fits with the outer surface of the pipe 1 to protect the platinum resistance thermometer body 201 installed on the outer surface of the pipe 1. Then, the two connecting plates 206 are loosened, and under the reset action of the first spring 207, the first curved plate 205 is driven to gradually approach the pipe 1 until the inner wall of the first curved plate 205 fits with the outer surface of the pipe 1. At this time, the first spring 207 is 7 is in a compressed state. Under the reset action of the first spring 207, the first spring 207 tends to expand outward, so that the first arc plate 205 is closely fitted with the pipe 1, thereby improving the stability of the protective shell 202 when limiting and fixing. When it is necessary to disassemble and inspect the platinum resistance thermometer, it is only necessary to pull the two connecting plates 206 in the opposite direction, and then disconnect the first fixing belt 208 and the second fixing belt 209 to release the limiting fixation of the protective shell 202, so that the protective shell 202 can be removed, so that the platinum resistance thermometer can be disassembled and inspected. The utility model can use the protective shell 202 added above the platinum resistance thermometer when using the platinum resistance thermometer to avoid the platinum resistance thermometer from being accidentally touched or pulled out, so as to ensure the accuracy of the measurement result, and limit and fix the protective shell 202 to provide stable protection for the platinum resistance thermometer. At the same time, when the platinum resistance thermometer needs to be disassembled and inspected, the protective shell 202 can be quickly disassembled and assembled, thereby improving the convenience and practicality of using the platinum resistance protection device.
