Description

Technical Field

[0001] The utility model relates to the technical field of instrument antifreeze, in particular to an antifreeze insulation cover for outdoor instruments. Background Art

[0002] As a commonly used instrument, the instrument is widely used in industrial production and other fields. Due to the characteristics of industrial production, the pipelines in industrial plants are usually complicated, so there are many types of instruments on the pipelines and they are distributed more dispersedly. Therefore, most of the instruments used in industry are exposed to the external environment, and the plant structure without special environmental requirements usually adopts a relatively simple floor frame or color steel house structure. Since this kind of plant structure is easily affected by the external temperature, in order to avoid unnecessary impact on the instrument in extreme weather, an adaptive antifreeze insulation cover is usually provided on the outside of the instrument and its pipeline to ensure the accuracy of the instrument's measurement data and service life.

[0003] At present, most commonly used insulation sleeve structures adopt detachable insulation sleeves. Although this insulation sleeve structure has a certain antifreeze and heat preservation effect, due to the dense and complex arrangement of pipelines, for instruments arranged at multiple pipeline connection positions, the adaptation structure of the insulation sleeve usually needs to be customized and the customized structure is usually provided with more notches and corresponding connectors. However, due to its special position, when this insulation sleeve structure is installed, on the one hand, it is not conducive to the connection between the connectors, and at the same time, the connection between the connectors is prone to unstable connection or incomplete fitting due to position deviation. On the other hand, the fit between this insulation sleeve structure and the outer wall of the instrument and its pipeline is not ideal, and for the pipe wall with certain curvature and angle restrictions at the connection between the instrument and its pipeline, the heat preservation effect of this insulation sleeve is further reduced. Utility Model Content

[0004] The utility model aims to provide an antifreeze and heat preservation cover for outdoor instruments, which can reduce the influence of the installation position of the outdoor instruments and further improve the fit and heat preservation effect.

[0005] The technical solution adopted by the utility model to solve the above problems is:

[0006] An antifreeze and heat preservation cover for outdoor instruments comprises a protective cover body, a plurality of elastic ropes are distributed around the outer periphery of the protective cover body, two ends of the elastic ropes are passed through matching openings provided on both sides of the protective cover body and connected with locking parts provided at the openings.

[0007] Further: the locking member includes a fixed seat and a movable seat, through holes are opened at corresponding positions on both sides of the fixed seat, the movable seat is slidably arranged in the fixed seat and is connected through a compression spring arranged inside the fixed seat, and the movable seat placed inside the fixed seat is provided with a connecting part for clamping the elastic rope, and a plurality of pressure teeth are distributed on the connecting part.

[0008] Further: the protective sleeve body is made of a telescopic sleeve structure and a plurality of sets of fixing rings and matching straps are distributed at the connection positions.

[0009] Furthermore: a plurality of suture lines are arranged at positions relative to the plurality of elastic ropes distributed around the periphery of the protective sleeve body.

[0010] Furthermore: the plurality of elastic ropes distributed on the protective cover body are arranged in a segmented structure and locking parts are arranged at the connection points at both ends.

[0011] Further: a plurality of the elastic ropes adapted to the protective sleeve main body structure are distributed on the protective sleeve main body in a horizontal and vertical staggered manner, and a connecting piece is provided on the elastic rope body.

[0012] Furthermore: the protective cover body is provided with a multi-layer structure, including an outer layer made of fireproof and high temperature resistant material, an inner layer made of heat resistant fabric, and an interlayer made of heat preservation and heat insulating material between the outer layer and the inner layer.

[0013] Furthermore: resistance wires for heating are arranged on the interlayer, and the resistance wires are connected to circuits provided on the protective sleeve body.

[0014] Compared with the prior art, the utility model has the following advantages and effects:

[0015] The utility model discloses an antifreeze insulation cover for outdoor instruments. The structure of the protective cover can be adapted according to the installation position of the specific instrument. During the installation process, the protective cover at the specific position is deformed due to the influence of a certain curvature or angle of the pipeline, so that the protective cover at the corresponding position of the pipeline is not completely fitted. When this happens, the elastic rope at the corresponding position of the outer periphery of the protective cover body is pulled by the locking member, so that the protective cover on the instrument and the pipeline at the corresponding position can be appropriately contracted, so as to further increase the fit of the protective cover, and facilitate the installation process. When the unstable fit occurs due to the dimensional error within a certain reasonable range during the customization and production of the protective cover, the several elastic ropes distributed around the periphery of the protective cover body can be flexibly adjusted to ensure the fit between the antifreeze and thermal insulation cover and the adapter instrument and the outer wall of the pipeline, further improving the adaptability and thermal insulation effect. In addition, the several elastic ropes locked and adjusted by the locking parts can also be wound and hung accordingly at the installation position according to specific usage requirements during the installation process, thereby improving the convenience of the installation process, facilitating installation and adjustment at different positions, and meeting different installation requirements.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] See also Figure 1-2 The present embodiment relates to an antifreeze and heat preservation cover for outdoor instruments, including a protective cover 1 main body, a plurality of elastic ropes 2 are distributed around the outer periphery of the protective cover 1 main body, and both ends of the elastic ropes 2 are passed through the adapter openings 11 provided on both sides of the protective cover 1 main body and connected with the locking parts 3 provided at the openings 11.

[0024] Specifically in this embodiment, see Figure 2 As shown, compared with the traditional protective insulation sleeve structure, during the installation process or when the initial fixation is completed, the elastic rope 2 surrounding the periphery of the protective sleeve 1 can be tightened and clamped by the locking member 3. The protective sleeve 1 body is further contracted under the tension of the elastic rope 2, thereby further increasing the fit between the protective sleeve 1 and the periphery of the instrument and the outer wall of the pipeline due to the large gap caused by the limitation of the pipeline arrangement and shape at the instrument position. The locking member 3 can adopt the buckle structure such as the spring buckle commonly used on the elastic rope 2, which is convenient for adjusting and clamping the tensile stress of the elastic rope 2. This kind of protective sleeve 1 structure can be adapted to the installation position of the specific instrument. During the installation process of the protective sleeve 1, the protective sleeve 1 at the specific position is deformed due to the influence of a certain curvature or angle of the pipeline, so that the protective sleeve 1 at the corresponding position of the pipeline is not completely fitted. When this happens, the elastic ropes 2 at the corresponding positions on the periphery of the main body of the protective sleeve 1 are pulled by the locking member 3, so that the protective sleeve 1 on the instrument and the pipeline at the corresponding position thereof can be appropriately shrunk, thereby further increasing the fit of the protective sleeve 1, and conveniently facing the unstable fit caused by the dimensional error within a certain reasonable range during the customization and production process of the protective sleeve 1 during the installation process, the several elastic ropes 2 distributed around the periphery of the main body of the protective sleeve 1 can be flexibly adjusted to ensure the fit of the antifreeze and heat preservation sleeve with the adapter instrument and the outer wall of the pipeline, thereby further improving the adaptability and heat preservation effect. In addition, the several elastic ropes 2 locked and adjusted by the locking member 3 can also be wound and hung accordingly at the installation position according to specific usage requirements during the installation process, thereby improving the convenience of the installation process, facilitating installation and adjustment at different positions, and meeting different installation requirements.

[0025] See also Figure 3The locking member 3 includes a fixed seat 31 and a movable seat 32. Through holes 311 are provided at corresponding positions on both sides of the fixed seat 31. The movable seat 32 is slidably arranged in the fixed seat 31 and is connected through the compression spring 4 provided inside the fixed seat 31. The movable seat 32 placed inside the fixed seat 31 is provided with a connecting portion 321 for clamping the elastic rope 2. A plurality of pressing teeth 3211 are distributed on the connecting portion 321. When installing, the locking member 3 is first pressed by pressing the movable seat 32 to slide accordingly in the fixed seat 31 so that the corresponding connecting portion 321 on the movable seat 32 is placed under the through holes 311 provided on both sides of the fixed seat 31. The elastic rope 2 is sequentially surrounded and passed through the through holes 311 provided at corresponding positions on both sides of the fixed seat 31 for installing and connecting the elastic rope 2. After the installation is completed, the movable seat 32 slides upward under the action of the compression spring 4 connected to it at the bottom of the fixed seat 31 until the connecting portion 321 provided on the movable seat 32 contacts the elastic rope 2 inserted in the through holes 311 on both sides of the fixed seat 31. If it is necessary to adjust the elastic rope 2 on the main body of the protective cover 1, the movable seat 32 can be repeatedly pressed to achieve the adjustment and clamping of the elastic rope 2. In addition, the several pressing teeth 3211 distributed on the connecting portion 321 of the movable seat 32 can further increase the friction and bite force on the elastic rope 2, and can further improve the shrinkage stability of the elastic rope 2 and its protective cover 1 main body without damaging the elastic rope 2, thereby ensuring the fit and fit stability of the protective cover 1 main body and the adapted instrument and the outer wall of its pipeline, and improving the antifreeze and heat preservation effect of this protective cover 1 during use.

[0026] The protective sleeve 1 is made of a telescopic sleeve structure and has multiple sets of fixing rings 12 and matching straps 13 distributed at the connection position. The specific structure of the straps 13 and the fixing rings 12 can be found in Figure 1 As shown, the protective cover 1 main body made of the telescopic cover structure can further improve the fit between the protective cover 1 and the outer wall of the instrument and the pipeline. In addition, the protective cover 1 using the telescopic cover structure can be telescoped to a certain extent and can be suitable for installation and protection on instruments and pipelines of different sizes and shapes within a certain telescopic range. At the same time, the protective cover 1 using the telescopic cover structure can be installed and fixed during the installation process through the straps 13 and the fixing rings 12 provided at the corresponding connecting positions on the protective cover 1 main body. The straps 13 can use Velcro straps 13 with suitable fixing rings 12 to facilitate the installation and fastening of the protective cover 1.

[0027] A plurality of sutures 14 are arranged at positions relative to the plurality of elastic cords 2 distributed around the periphery of the protective sleeve 1. Figure 2As shown in the figure, the stitching lines 14 at the corresponding positions can further improve the overall structural strength of the protective cover 1 body, reduce the occurrence of damage that affects the performance, and can also effectively prevent the protective cover 1 body from causing the elastic rope 2 to shift during long-term installation and use, thereby affecting the use effect. The line formed by the stitching lines 14 can also reduce the deformation of the protective cover 1 during the installation process, and is also convenient for the threading and replacement of the elastic rope 2 and other operational requirements.

[0028] See also Figure 4 The plurality of elastic ropes 2 distributed on the main body of the protective cover 1 are arranged in a segmented structure and are provided with locking members 3 at both ends of the connection. The plurality of elastic ropes 2 arranged in a segmented structure cooperate with the locking members 3 connected at both ends, so that the main body of the protective cover 1 can be locally adjusted at corresponding positions according to the specific installation position and its adaptability during the installation process through the elastic ropes 2 and the locking members 3 at corresponding positions, thereby further increasing the adaptability of the protective cover 1, facilitating adaptive adjustment according to the specific installation position and the specific shape of the instrument and the corresponding pipeline, and improving flexibility and convenience during use.

[0029] The plurality of elastic ropes 2 adapted to the main structure of the protective cover 1 are distributed on the main body of the protective cover 1 in a horizontal and vertical staggered manner, and a connecting piece 21 is provided on the rope body of the elastic rope 2. The plurality of elastic ropes 2 distributed on the main body of the protective cover 1 in a horizontal and vertical staggered manner can further improve the adjustability of the main body of the protective cover 1, because there is a reasonable range of size difference between its customized structure and the instrument and pipeline shape at the actual corresponding installation position. When this situation occurs or is affected by the specific installation structure at its installation position during the installation of the protective cover 1, the main body of the protective cover 1 can be offset at a specific position. By adapting the elastic ropes 2 set on the main structure of the protective cover 1, the main body of the protective cover 1 can be stretched and retracted to appropriate lengths in the horizontal and vertical directions, so that the main structure of the protective cover 1 is more compact while meeting different installation requirements and improving the fit.

[0030] The main body of the protective cover 1 is provided with a multi-layer structure, including an outer layer 101 made of fireproof and high-temperature resistant material, an inner layer 103 made of heat-resistant fabric, and an interlayer 102 made of heat-insulating material between the outer layer 101 and the inner layer 103. The outer layer 101 made of high-temperature resistant material can provide effective fireproof and high-temperature resistant performance, protecting the protective cover 1 from damage in high-temperature environment; the inner layer 103 made of heat-resistant fabric can reduce the degree of damage to the inside of the main body of the protective cover 1 caused by temperature changes when it is in direct contact with the instrument and the outer wall of the pipeline, and the fabric structure can further increase the anti-slip cover The contact area between the interior of the main body and the instrument and the outer wall of its pipeline also has a certain air permeability, which avoids unnecessary influence on the outer wall of the instrument and its pipeline due to moisture generated by changes in surface or external environment temperature during long-term use; in addition, the interlayer 102 made of thermal insulation material between the outer layer 101 and the inner layer 103 can reduce a certain amount of heat loss while preventing cold wind from entering the inner layer 103, thereby improving the antifreeze and heat preservation performance of this protective cover 1. The protective cover 1 main body with such a multi-layer structure can further improve the performance while ensuring stability during use, and appropriately extend the service life.

[0031] The interlayer 102 is provided with a resistance wire 5 for heating, and the resistance wire 5 is connected to the circuit provided on the main body of the protective sleeve 1. The heating resistance wire 5 arranged on the interlayer 102 can be connected to the circuit provided at the corresponding installation position through the circuit provided on the main body of the protective sleeve 1 according to specific usage requirements, so that the main body of the protective sleeve 1 can be properly heated through the resistance wire 5 provided on the interlayer 102, thereby achieving a certain thermal insulation effect in extreme weather with low temperature, and meeting different usage conditions and usage requirements.
