Description

Technical Field

[0001] This utility model relates to the technical field of temperature measuring equipment for concrete construction, and specifically to a temperature measuring instrument for concrete construction in winter. Background Technology

[0002] In the field of winter concrete construction, the internal temperature of concrete is a core monitoring indicator for evaluating the effectiveness of antifreeze curing measures and ensuring structural strength and durability. Therefore, accurate on-site temperature measurement is a key aspect of construction management.

[0003] However, most existing temperature measuring lines are simple rods without anchoring structures, relying only on the friction of the inner wall of the temperature measuring hole or the limitation of the external simple filler. Under the strong disturbance of concrete pouring and vibration and the stress of solidification shrinkage, they are very prone to vertical movement or lateral displacement, causing the temperature measuring probe to fall off the preset monitoring point. The collected temperature data cannot reflect the true working condition of the core area of ​​the concrete. In severe cases, it can mislead the decision on antifreeze curing and create potential structural safety hazards.

[0004] Furthermore, the temperature sensors of traditional temperature measuring lines are either directly exposed and easily damaged by impacts from aggregates and squeezing from vibrators during the pouring process, significantly shortening the service life of the equipment; or they are made of fully enclosed fixed protective shells, which isolate the sensor from direct contact with the concrete. This not only results in a slow temperature measurement response speed but also causes a large measurement error due to thermal conduction obstruction. In addition, the compatible sensor models are limited, making it difficult to meet the temperature measurement needs of different accuracies and working conditions.

[0005] Meanwhile, existing temperature measuring line plugs are mostly protected by simple methods such as plastic bags and cling film, without a dedicated fixing structure. Under the influence of rain, snow, frost, and concrete slurry splashes during winter construction, the protective layer is prone to peeling off, the plug gets damp and short-circuited, or it becomes contaminated with impurities, resulting in poor contact and making it impossible to guarantee stable data transmission. Utility Model Content

[0006] The purpose of this invention is to provide a temperature measuring instrument for concrete construction in winter, in order to solve the problems in the prior art such as easy displacement of the temperature measuring wire, difficulty in balancing sensor protection and temperature measurement accuracy, and unstable data transmission due to insufficient plug protection.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a temperature measuring instrument for concrete construction in winter, comprising:

[0008] The temperature measuring device component is used to display the transmitted temperature data via handheld plug-in and push-button switch;

[0009] A temperature measuring wire assembly, embedded in a pre-drilled temperature measuring hole during winter concrete construction, includes a rod, a probe, an anchor, and a connector. The rod, serving as the temperature measuring wire body, is inserted into the pre-drilled temperature measuring hole. The probe is located at the lower end of the rod and is used to detect the concrete temperature and protect the probe. The anchor is located in the middle of the rod and within the temperature measuring hole, providing anti-displacement anchoring force for the rod. The connector is located at the upper end of the rod and is used to connect to the temperature measuring instrument assembly for temperature data transmission.

[0010] A protective cover assembly is fitted over the connector to protect the connector and the rod extending out of the temperature measuring hole.

[0011] Furthermore, the temperature measuring instrument assembly includes an instrument body, which is equipped with a display screen and buttons. The input end of the instrument body is connected to a connecting cable, and the other end of the connecting cable is fixedly installed with an interface.

[0012] Furthermore, the probe includes a temperature sensor disposed at the lower end of the rod for detecting the temperature of the poured concrete, and a petal-shaped protective shell is also fixedly installed at the lower end of the rod, the petal-shaped protective shell surrounding the outside of the temperature sensor.

[0013] Furthermore, the anchor includes an annular groove formed in the middle of the rod body, with spring steel fixedly installed at the bottom of the annular groove. Multiple sets of spring steel are provided to surround the annular groove; barbs are fixedly installed on the top of each spring steel.

[0014] Furthermore, the connector includes a plug fixedly disposed at the upper end of the rod body, the plug being used to cooperate with the interface to transmit the measured temperature data; the upper end of the rod body is also provided with a sliding groove, multiple sets of the sliding groove are provided around the rod body, and a slot is provided downward along the inner side of the sliding groove along the rod body.

[0015] Furthermore, the protective cover assembly includes a cover body, a slide rod is fixedly installed around the lower outer side of the cover body, the slide rod is slidably disposed in a slide groove, and an insert rod is also fixedly installed on the lower inner side of the slide rod, the insert rod is inserted into the slot.

[0016] Compared with existing technologies, the temperature measuring instrument provided by this utility model for winter concrete construction adopts a barbed elastic anchor design, which ensures smooth insertion and strong reverse anchoring force, preventing displacement of the temperature measuring line, ensuring accurate temperature measurement points, and improving data reliability. Furthermore, the petal-shaped protective shell, which combines insertion protection and temperature measurement upon arrival, works in conjunction with a temperature sensor to achieve a balance between safety protection and rapid, accurate temperature measurement.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Example:

[0028] This utility model provides a temperature measuring instrument for concrete construction in winter, as shown in the attached figure. Figure 1 As shown, it includes:

[0029] The temperature measuring instrument component 100 is used to display the transmitted temperature data via handheld plug-in and push-button switch;

[0030] The temperature measuring wire assembly 200, embedded in a pre-reserved temperature measuring hole during winter concrete construction, includes a rod 201, a probe 202, an anchor 203, and a connector 204. The rod 201 serves as the temperature measuring wire body and is inserted into the pre-reserved temperature measuring hole. The probe 202 is located at the lower end of the rod 201 and is used to detect the concrete temperature and protect the probe. The anchor 203 is located in the middle of the rod 201 and within the temperature measuring hole, providing anti-displacement anchoring force for the rod 201. The connector 204 is located at the upper end of the rod 201 and is used to connect to the temperature measuring instrument assembly 100 for temperature data transmission. A high-strength, lightweight metal rod is used as the rod 201 to ensure sufficient support strength and easy insertion into the temperature measuring hole.

[0031] The protective cover assembly 300 is placed over the connector 204 to protect the connector 204 and the rod 201 extending out of the temperature measuring hole.

[0032] As attached Figure 2 As shown, the temperature measuring instrument assembly 100 includes an instrument body 101, which is equipped with a display screen and buttons. A connecting cable 102 is connected to the input end of the instrument body 101, and an interface 103 is fixedly installed at the other end of the connecting cable 102. The instrument body 101 may be of models including, but not limited to, JDC-2, JDC-3, and TP101. A flexible and wear-resistant connecting cable 102 is selected, with one end fixedly connected to the signal input end of the instrument body 101 by welding, and the other end fixed to the interface 103 by threaded fastening, ensuring the connection stability between the connecting cable 102 and the interface 103 and avoiding poor contact during data transmission. The instrument body 101 integrates a power module, a signal receiving module, and a data processing module, which are connected by lines to realize power supply, signal reception, and data conversion and display functions.

[0033] As attached Figure 3As shown, the probe 202 includes a temperature sensor 202b disposed at the lower end of the rod 201 for detecting the temperature of the poured concrete. A petal-shaped protective shell 202a is also fixedly installed at the lower end of the rod 201, surrounding the temperature sensor 202b. The temperature sensor 202b is embedded in a mounting hole at the lower end of the rod 201 and sealed with sealant to prevent concrete slurry from seeping in. The petal-shaped protective shell 202a is then fixed to the lower end of the rod 201 with bolts, ensuring that the hard alloy petal-shaped protective shell 202a completely surrounds and encloses the temperature sensor 202b. In the initial state, the petal-shaped protective shell 202a is closed, forming a protective cone to protect the temperature sensor 202b from damage during insertion. When it reaches the bottom of the temperature measuring hole, the petal-shaped protective shell 202a slightly opens due to the obstruction of the bottom concrete and the weight of the rod 201 itself, exposing the internal direct contact temperature sensor 202b and allowing it to fully contact the concrete for rapid temperature measurement. The model of the temperature sensor 202b includes, but is not limited to, DS18B20+ and MAX31850.

[0034] As attached Figure 4 As shown, the anchor 203 includes an annular groove 203a opened in the middle of the rod body 201. A spring steel 203b is fixedly installed at the bottom of the annular groove 203a. Multiple sets of spring steel 203b are provided to surround the annular groove 203a. A barb 203c is fixedly installed on the top of each spring steel 203b. A circumferential groove 203a is formed in the middle of the rod 201. The depth of the groove 203a is determined according to the height of the spring steel 203b. Multiple sets of spring steel 203b are evenly distributed and fixed to the bottom of the groove 203a by welding. The spring steel 203b is in a naturally inclined state with an outward opening angle of 30-45°. Barbs 203c are welded to the top of the spring steel 203b. The barbs 203c are made of sharp metal material to ensure that they can effectively embed into the inner wall of the temperature measuring hole. The barbs 203c fit the rod 201 in the forward direction. When the rod 201 is inserted into the temperature measuring hole, the resistance is minimal, making it easy to insert. When the concrete begins to solidify or external force attempts to pull out the rod 201, the barbs 203c open and embed into the concrete under the reverse resistance, thereby providing a strong anti-displacement anchoring force to ensure that the measuring point position is accurate and does not shift.

[0035] As attached Figure 5 As shown, the connector 204 includes a plug 204a fixedly disposed on the upper end of the rod 201. The plug 204a is used to cooperate with the interface 103 to transmit the measured temperature data. The upper end of the rod 201 also has a sliding groove 204b. Multiple sets of sliding grooves 204b are formed around the rod. The inner side of the sliding groove 204b is also provided with a slot 204c downward along the rod 201.

[0036] As attached Figure 6 As shown, the protective cover assembly 300 includes a cover body 301. A slide rod 302 is fixedly installed around the lower outer side of the cover body 301. The slide rod 302 is slidably disposed in the slide groove 204b. An insert rod 303 is also fixedly installed on the lower inner side of the slide rod 302. The insert rod 303 is inserted into the slot 204c. The cover 301 is made of rigid waterproof plastic material. The inner diameter of the cover 301 is larger than the outer diameter of the upper end of the rod 201, ensuring that the cover 301 can completely cover the plug 204a and the exposed part of the rod 201. Slide rods 302 are uniformly fixedly installed circumferentially on the lower outer side of the cover 301. The number of slide rods 302 is the same as the number of slide grooves 204b on the rod 201. The width of the slide rods 302 is slightly smaller than the width of the slide grooves 204b, ensuring that the slide rods 302 can slide smoothly along the slide grooves 204b. The insertion rod 303 is integrally molded on the lower inner side of the slide rods 302 through injection molding. The length of the insertion rod 303 is 2-3cm, and the diameter matches the inner diameter of the slot 204c, ensuring that the insertion rod 303 can be tightly inserted into the slot 204c for fixation.

[0037] The application process of temperature measuring instruments in winter concrete construction is mainly divided into three stages: pre-embedded installation, pouring, curing and protection, and temperature measurement operation.

[0038] Pre-installation stage: First, based on the winter construction temperature measurement plan, determine the location, number, and depth of the temperature measurement points. Before concrete pouring, use a sleeve matching the specifications of the temperature measurement hole to pre-reserve temperature measurement holes at the preset temperature measurement points. The depth of the temperature measurement hole is determined according to the temperature measurement requirements, usually not less than 1 / 2 of the thickness of the concrete component. Vertically insert the assembled temperature measurement wire assembly 200 into the temperature measurement hole. During the insertion process, the spring steel 203b is squeezed and contracted by the inner wall of the temperature measurement hole, allowing the rod 201 to be smoothly inserted until the probe 202 reaches the preset temperature measurement depth. After the spring steel 203b is fully inserted into the temperature measurement hole, it opens outward under its own elasticity. The barb 203c at the top of the spring steel 203b embeds into the concrete or filling medium of the inner wall of the temperature measurement hole, realizing the stable anchoring of the temperature measurement wire assembly 200 and preventing the rod 201 from shifting up and down or left and right. Leave the plug 204a at the upper end of the rod 201 outside the temperature measurement hole to ensure that the plug 204a is not contaminated by concrete slurry.

[0039] During the pouring, curing, and protection stage: Before concrete pouring, a protective cover assembly 300 is installed to protect the plug 204a. Specifically, the sliding rod 302 of the protective cover assembly 300 is aligned with the groove 204b on the rod 201. The cover 301 is then slid downwards along the groove 204b until the insert 303 at the lower end of the sliding rod 302 is fully inserted into the slot 204c. At this point, the cover 301 is tightly fitted against the concrete surface outside the temperature measuring hole, completely covering the plug 204a and the exposed part of the rod 201, achieving moisture-proof, dust-proof, and collision-proof protection. This protection is applied during concrete pouring and vibration. During the process, the rod 201 of the temperature measuring wire assembly 200 provides stable support for the probe 202. The petal-shaped protective shell 202a effectively prevents the aggregate and vibrator from impacting and squeezing the temperature sensor 202b. The anchor 203 continuously provides anchoring force to ensure that the temperature measuring wire assembly 200 is always in the preset position. During the entire curing period, the protective cover assembly 300 continuously protects the plug 204a and the exposed rod 201 to prevent rain, snow, frost and water from entering the plug 204a during winter construction and during concrete curing, and to prevent the plug 204a from getting damp, short-circuiting or becoming contaminated with impurities.

[0040] Temperature measurement operation stage: When temperature monitoring is required, the construction worker holds the thermometer assembly 100, first pulls the protective cover assembly 300 upwards to disengage the insertion rod 303 from the slot 204c, then slides the cover 301 upwards along the slide groove 204b to remove the protective cover assembly 300; presses the button on the thermometer assembly 100 to turn on the power, and confirms that the instrument is working normally through the display screen; precisely connects the interface 103 of the thermometer assembly 100 to the plug 204a of the temperature measuring wire assembly 200 to ensure a stable connection; after the interface 103 and plug 204a are connected, the temperature sensor 202b collects the internal temperature of the concrete. Temperature data is transmitted to plug 204a via the internal wiring of rod 201, and then to the data processing module of instrument body 101 via interface 103 and connecting cable 102. The data processing module converts the collected signal into temperature value, which is displayed in real time on the display screen. Construction personnel read and record the temperature data on the display screen to complete the monitoring of one temperature measurement point. After the temperature measurement is completed, the connection between interface 103 and plug 204a is disconnected, the power of the thermometer is turned off, and then the protective cover assembly 300 is reinstalled in its original position to continue to protect plug 204a. The above temperature measurement operation procedure can be repeated for subsequent temperature measurements.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
