Description

Technical Field

[0001] This utility model relates to the technical field of water meter insulation sleeves, specifically to an automatic temperature-controlled antifreeze water meter insulation sleeve. Background Technology

[0002] A water meter insulation sleeve is used to wrap the water meter, providing protection and insulation. Water meters are instruments that measure water flow and are mostly installed outdoors. In cold winter weather, the water flow can freeze. In some remote mountainous or extremely cold regions, the large temperature difference between day and night can cause outdoor water meters to harden due to the temperature difference, resulting in no water flow. Therefore, an antifreeze water meter insulation sleeve is needed.

[0003] Compared to existing water meter insulation sleeves, conventional water meter insulation sleeves have the following drawbacks: In some remote mountainous or extremely cold regions, the temperature difference between day and night can cause ordinary insulation sleeves to fail to provide protection at night. As the temperature drops, the water will freeze and eventually stop flowing. With continued hardening, the water pipes will eventually burst. At the same time, due to the different installation positions of different water meters and valves, conventional water meter insulation sleeves cannot provide a tight connection, allowing cold air to enter. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic temperature-controlled antifreeze water meter insulation sleeve to solve the following technical problems: In some remote mountainous or extremely cold regions, conventional water meter insulation sleeves cannot provide protection at night due to the temperature difference between day and night. The water will freeze due to the drop in temperature, eventually causing the water flow to stop. As the water continues to harden, it will eventually cause the water pipe to burst. At the same time, the installation positions of different water meters and valves are different, and conventional water meter insulation sleeves cannot be tightly connected, allowing cold air to enter.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An automatic temperature-controlled antifreeze water meter insulation sleeve includes: a water meter body; a wrap-around windproof cloth is provided on the outside of the water meter body, and a second Velcro and a first Velcro are respectively provided on the upper and lower sides of the windproof cloth to seal the water meter body with the windproof cloth; and a heating fabric connected to a detachable soft-pack lithium battery is provided inside the windproof cloth.

[0007] The windproof cloth is provided with nylon pull ropes on the inner sides of both the left and right ends. A connecting box is provided at the upper end of the nylon pull ropes, and a limiting rod is provided on the inner side of the connecting box to prevent the nylon pull ropes from falling off.

[0008] As a further embodiment of this utility model: the inner side of the windproof cloth is provided with aerogel felt, heating fabric, aluminum foil reflective film and heat insulation cotton that are stacked in sequence.

[0009] As a further embodiment of this utility model: the windproof cloth, aerogel felt, heating fabric, aluminum foil reflective film and thermal insulation cotton are bonded and fixed to each other to form an integrated structure.

[0010] As a further aspect of this utility model: the first hook and loop fastener consists of a rough side and a hook side, used to adhere the rough side and the hook side to each other.

[0011] As a further embodiment of this utility model: the pull strips are evenly distributed at both ends of the windproof cloth, and are used to adjust the width according to the protruding dimensions of the water meter body.

[0012] As a further embodiment of this utility model: the nylon pull rope is disposed through the inner cavity groove on the left and right sides of the windproof cloth, and the upper inner side of the nylon pull rope is provided with equidistant positioning holes and grooves.

[0013] As a further embodiment of this utility model: the limiting rod passes through the limiting hole groove and into the inner side of the nylon pull rope, and is used to limit and fix the nylon pull rope that passes through the connecting box.

[0014] As a further embodiment of this utility model: the limiting rod forms an elastic telescopic structure within the connecting box via a spring, and the limiting rod and the pull rod are vertically fixedly connected;

[0015] The pull rod forms a snap-fit ​​sliding structure within the connecting box.

[0016] The beneficial effects of this utility model are:

[0017] 1. The heating fabric is powered by a detachable soft-pack lithium battery, which enables the heating fabric to be heated at a constant temperature. This keeps the inner cavity of the windproof fabric at a constant temperature, which can prevent the water pipes and water meters from bursting due to the large temperature difference between day and night.

[0018] Additionally, nylon pull ropes are installed through the inner cavity of both ends of the windproof cloth. By tightening and limiting the nylon pull ropes, the inner diameter of the left and right ends of the windproof cloth can be adjusted to ensure that the inner diameter fits and seals with the port of the water meter. With the pull strips evenly distributed on the upper surface of the left and right sides of the windproof cloth, the opening can be sealed after the water meter is installed, reducing the entry of cold air.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 3 , Figure 4 and Figure 5 As shown, this utility model is an automatic temperature-controlled antifreeze water meter insulation sleeve, specifically capable of automatically controlling the temperature to maintain a constant internal temperature. It includes a water meter body 1; a wrap-around windproof cloth 2 is provided on the outside of the water meter body 1, and a second Velcro 4 and a first Velcro 3 are respectively provided on the upper and lower sides of the windproof cloth 2 to seal the water meter body 1. A heating fabric 202 connected to a detachable soft-pack lithium battery 5 is provided inside the windproof cloth 2.

[0030] In this embodiment, preferably, the inner side of the windproof cloth 2 is provided with aerogel felt 201, heating fabric 202, aluminum foil reflective film 203 and heat insulation cotton 204 stacked in sequence.

[0031] In this embodiment, preferably, the windproof cloth 2, aerogel felt 201, heating fabric 202, aluminum foil reflective film 203 and heat insulation cotton 204 are bonded and fixed to each other to form an integrated structure.

[0032] In this embodiment, preferably, the first hook and loop fastener 3 is composed of a rough surface 301 and a hook surface 302, which are used to stick the rough surface 301 and the hook surface 302 to each other.

[0033] In summary, first, pull open the first Velcro 3 and place the windproof cloth 2 on the outside of the water meter body 1. Through the slots on the upper left and right sides of the windproof cloth 2, the valve part of the water meter body 1 can be exposed on the outside of the windproof cloth 2. Then, close the first Velcro 3. Since the first Velcro 3 is composed of a rough side 301 and a hook side 302, it can close and connect the lower end of the windproof cloth 2. At this time, extend the pull strip 6 backward in sequence and stick it to the windproof cloth 2 through the third Velcro 7, so that the slots on the upper left and right sides of the windproof cloth 2 are closed. Finally, pull the nylon pull rope 9 to tighten the left and right ends of the windproof cloth 2, and the installation operation is completed.

[0034] Furthermore, the windproof fabric 2 is composed of aerogel felt 201, heating fabric 202, aluminum foil reflective film 203, and insulation cotton 204. The windproof fabric 2 uses double-coated thickened Oxford cloth, employing a four-layer design. The coating is applied using a special process, resulting in high flexural strength, waterproofing, cold protection, corrosion resistance, aging resistance, and good insulation performance. The heating fabric 202 is connected to a removable soft-pack lithium battery 5 via an electrical wire. Continuous power from the removable soft-pack lithium battery 5 allows the heating fabric 202 to be heated, thus... The windproof fabric 2 is kept at a constant temperature to prevent cold air from entering and freezing water in remote or extremely cold areas where there are large temperature differences between day and night. The heating fabric 202 has a similar structural principle to an electric blanket, mainly composed of conductive materials, electrodes, and NTC thermistors. The insulation cotton 204 is made of 300g polyester fiber cotton, which has fine fibers, natural crimp, and a cavity in the cross-section, providing good warmth retention and strong heat storage capacity. The first hook and loop fastener 3, the second hook and loop fastener 4, and the third hook and loop fastener 7 are all made of nylon.

[0035] In addition, the extended design of the left and right ends of the windproof cloth 2 allows the straight pipe section and valve interface of the water meter body 1 to be covered with insulation. The use of the first hook and loop fastener 3, the second hook and loop fastener 4 and the third hook and loop fastener 7 makes the installation simpler. When it is necessary to check the meter later, the data can be viewed by simply opening the second hook and loop fastener 4.

[0036] Example 2

[0037] Reference Figure 1 , Figure 2 and Figure 3 The image shows the second embodiment of this utility model, which is specifically designed to be adjustable and installed according to the size of the water meter to achieve a sealed connection. This includes nylon pull ropes 9 on the inner sides of both ends of the windproof cloth 2, a connecting box 11 at the upper end of the nylon pull ropes 9, and a limiting rod 12 to prevent the nylon pull ropes 9 from falling off on the inner side of the connecting box 11.

[0038] In this embodiment, preferably, the pull strips 6 are evenly distributed at both ends of the windproof cloth 2, and are used to adjust the width according to the protruding size of the water meter body 1.

[0039] In this embodiment, preferably, the nylon pull rope 9 is disposed through the inner cavity groove 8 on the left and right sides of the windproof cloth 2, and the upper inner side of the nylon pull rope 9 is provided with equidistant limiting holes and grooves 10.

[0040] In this embodiment, preferably, the limiting rod 12 passes through the limiting hole groove 10 and penetrates the inner side of the nylon pull rope 9, and is used to limit and fix the nylon pull rope 9 that passes through the connecting box 11.

[0041] In this embodiment, preferably, the limiting rod 12 forms an elastic telescopic structure in the connecting box 11 through the spring 13, and the limiting rod 12 and the pull rod 14 are vertically fixedly connected.

[0042] The pull rod 14 forms a snap-fit ​​sliding structure within the connecting box 11.

[0043] In summary, after the windproof cloth 2 is fixedly wrapped around the outside of the water meter body 1, since the valve positions of the water meter body 1 are not uniform on the left and right sides, the openings on the upper surfaces of the left and right sides of the windproof cloth 2 allow for installation according to the valve's diameter or other dimensions. Furthermore, after installation, the pull strip 6 is pulled back and secured to the windproof cloth 2 using the third Velcro 7, tightening and closing the openings to prevent cold air from entering through gaps. Finally, the inner cavity grooves 8 on the inner sides of the left and right ends of the windproof cloth 2 are closed. The nylon pull rope 9, which runs through the nylon pull rope, is pulled upwards and then passes through the interior of the connecting box 11. Limiting holes 10 are equidistantly provided on the upper side of one end of the nylon pull rope 9. At this time, pulling the pull rod 14 outwards allows the limiting rod 12 to form a snap-fit ​​sliding connection in the connecting box 11 under the elastic extension and contraction of the spring 13. Then, the limiting rod 12 passes through the limiting hole 10 and passes through the nylon pull rope 9, thereby limiting and fixing the nylon pull rope 9 that tightens the end of the windproof cloth 2 when pulled.

[0044] Example 3

[0045] This embodiment is obtained by combining Embodiment 1 and Embodiment 2.

[0046] The above-mentioned constant temperature control setting of the heated fabric 202 and the pull-pull tightening operation of the pull strip 6 and the nylon pull rope 9 can not only keep the windproof fabric 2 in a constant temperature state, but also tighten the two ends of the windproof fabric 2 to prevent cold air from entering. In addition, the first Velcro 3 and the second Velcro 4 are used for opening and adhesion, which facilitates subsequent meter reading and reference.
