Description

Technical Field

[0001] This application relates to the technical field of concrete specimen curing, and particularly to an environmental simulation curing device for concrete specimens. Background Art

[0002] Concrete specimens are cubic specimens used to determine the compressive strength of concrete. Concrete specimens need to be cured for a period of time before being put into use. Currently, the curing methods for concrete specimens are divided into standard curing methods and same-condition curing methods.

[0003] The traditional same-condition curing method is to simulate the environment of a curing room to cure concrete specimens in the absence of a standard curing room. The current simulation method is to place the fabricated concrete specimens in still water at a temperature of 20 ± 3°C for curing. Most of the existing simulation curing devices are relatively simple, with a low degree of integration, resulting in a cumbersome operation process and requiring regular manual supervision. Utility Model Content

[0004] In view of the above problems, the embodiments of this application provide an environmental simulation curing device for concrete specimens, which has a higher degree of integration, is convenient to operate, and does not require regular manual supervision.

[0005] According to one aspect of the embodiments of this application, an environmental simulation curing device for concrete specimens is provided. The environmental simulation curing device for concrete specimens includes a water tank, a PLC control box, and a plurality of curing boxes arranged on the top of the water tank. A heat exchange device and a temperature sensor are arranged in the water tank. The plurality of curing boxes are arranged at equal intervals on the top of the water tank. A retaining box is placed inside the curing box. The top end face of the retaining box is lower than the top end face of the curing box. A water pump is arranged on the outside of the curing box. The water inlet end of the water pump is communicated with the water tank, and the water outlet end of the water pump extends into the inner cavity of the curing box. The bottom of the curing box is communicated with the water tank through a return pipe. An electromagnetic valve is arranged on the return pipe. A liquid level sensor is arranged on the inner side wall of the curing box. The height of the liquid level sensor is higher than the height of the top end face of the retaining box. The heat exchange device, the temperature sensor, the liquid level sensor, the electromagnetic valve, and the water pump are all electrically connected to the PLC control box.

[0006] In some embodiments, two handles are symmetrically arranged on the outer side wall of the retaining box.

[0007] In some embodiments, a plurality of strip-shaped support sleepers are arranged on the inner bottom wall of the curing box, and the plurality of support sleepers are arranged at equal intervals in the curing box.

[0008] In some embodiments, a nameplate box is provided on the outer sidewall of the maintenance box. The nameplate box is a box structure with an open top, and the sidewall of the nameplate box away from the maintenance box is made of a transparent material.

[0009] In some embodiments, it includes a sunshade. The sunshade is arranged on the tops of multiple maintenance boxes. A support rod is connected to the bottom of the sunshade, and the bottom of the support rod is screwed to the top of the water tank through a threaded sleeve.

[0010] In some embodiments, a water injection pipe is provided on the top of the water tank. The water injection pipe is communicated with the water tank, and an end cover is provided on the top of the water injection pipe.

[0011] In some embodiments, a plurality of universal rollers are provided at the bottom of the water tank.

[0012] The beneficial effects of the present application are as follows: By setting up a heat exchange device and a temperature sensor and interacting with the PLC control box, the heat exchange device can change the temperature of the water in the water tank according to the temperature detected by the temperature sensor, so that the water in the water tank always meets the maintenance requirements. The present application also sets up a retention box and a maintenance box. The retention box is located inside the maintenance box and its height is lower than that of the maintenance box. Therefore, the present application can complete the water injection into the retention box by injecting water into the maintenance box, and is paired with a liquid level sensor. When the water level rises to the liquid level sensor, the water pump stops injecting water. Also, since the height of the liquid level sensor is higher than that of the recording box, the retention box is already filled with water at this time. On the other hand, when the external temperature changes, under the action of the water pump, the water in the water tank enters the maintenance box, and the water in the maintenance box flows back into the water tank through the return pipe to complete the exchange. After the water in the maintenance box and the water tank completes the cycle, the water temperature in the maintenance box also meets the maintenance requirements. Further, after the water in the maintenance box and the water in the retention box undergo heat exchange, the water temperature in the retention box will also meet the maintenance requirements, and the water flow in the retention box will not be disturbed during this process, and the water flow in the retention box remains stagnant water, meeting the specification requirements.

[0022] Specifically, please refer to Figures 1 to 4 , Figure 1 Schematic diagram of the overall structure of the environmental simulation curing device for concrete test blocks provided by an embodiment of the present application, Figure 2 Partial structural schematic diagram at the water tank provided by an embodiment of the present application, Figure 3 Side sectional structural schematic diagram of the overall environmental simulation curing device for concrete test blocks provided by an embodiment of the present application, Figure 4This is a schematic diagram of a partial structure at the retention box provided by an embodiment of the present application. An environmental simulation curing device 100 for concrete test blocks includes a water tank 110, a PLC control box 160, and a plurality of curing boxes 120 arranged on the top of the water tank 110. The water tank 110 is used to store liquid water. The liquid water in the water tank 110 can be pumped into each curing box 120 through a water pump 140 to complete the water injection for each one. In the embodiment of the present application, each curing box 120 is used to store concrete test blocks of the same batch. Three to five concrete test blocks can be stored in one curing box 120. The specific size of the curing box 120 can be set according to actual situations such as the size and quantity of the test blocks. The PLC control box 160 is used to control a plurality of electrical components. A heat exchange device 111 and a temperature sensor 112 are arranged in the water tank 110. The temperature sensor 112 is used to detect the temperature of the liquid water in the water tank 110 and transmit the detection signal to the PLC control box 160. After the PLC control box 160 detects that the temperature value change exceeds the limit, it further transmits an instruction to the heat exchange device 111. After receiving the above instruction, the heat exchange device 111 starts and changes the temperature of the liquid water in the water tank 110, so that the temperature of the liquid water in the water tank 110 is moderate to meet the curing requirements. The plurality of curing boxes 120 are arranged at equal intervals on the top of the water tank 110. The arrangement form of the curing boxes 120 can be a single row or multiple rows. A retention box 130 is placed inside the curing box 120. The retention box 130 is not fixed to the curing box 120, so the retention box 130 can be taken out of the curing box 120 for cleaning. The concrete test blocks are placed inside the retention box 130. The top end face of the retention box 130 is lower than the top end face of the curing box 120, so that after the liquid level of the liquid water in the curing box 120 exceeds the top end face of the curing box 120, the liquid water can overflow into the retention box 130. A water pump 140 is arranged outside the curing box 120. The water inlet end of the water pump 140 is connected to the water tank 110, and the water outlet end of the water pump 140 extends into the inner cavity of the curing box 120. The water pump 140 can pump the water pump 140 in the water tank 110 that meets the curing requirements into the curing box 120. The bottom of the curing box 120 is connected to the water tank 110 through a return pipe 121. An electromagnetic valve 122 is arranged on the return pipe 121. When the electromagnetic valve 122 is opened, the liquid water in the curing box 120 will enter the water tank 110 through the return pipe 121. A liquid level sensor 123 is arranged on the inner side wall of the curing box 120. The height of the liquid level sensor 123 is higher than the height of the top end face of the retention box 130. The liquid level sensor 123 is used to detect the water level height in the curing box 120. The heat exchange device 111, the temperature sensor 112, the liquid level sensor 123, the electromagnetic valve 122, and the water pump 140 are all electrically connected to the PLC control box 160. The PLC control box 160 can independently control the heat exchange device 111, the temperature sensor 112, the liquid level sensor 123, the electromagnetic valve 122, and the water pump 140 respectively.

[0023] In the embodiment of the present application, during the specific operation process, the operator places the concrete manual test block in the retention box 130, and then turns on the water pump 140. The water pump 140 pumps the liquid water in the water tank 110 to the curing box 120. When the water level in the curing box 120 is higher than the top of the retention box 130, the water in the curing box 120 will overflow into the retention box 130. Until the retention box 130 is filled, with the continuous operation of the water pump 140, the liquid level of the curing box 120 will continue to rise. When the liquid level rises to the liquid level sensor 123, the liquid level sensor 123 will send an electrical signal to the PLC control box 160, and then the PLC control box 160 sends it to the corresponding water pump 140, and the water pump 140 stops pumping water. In another working environment, when the ambient temperature changes, the water temperature in the curing box 120 will also change accordingly (the water temperature in the curing box 120 is required to be still water at 20±3°C). Therefore, in order to avoid the change of the ambient temperature affecting the water temperature in the retention box 130, under the control of the PLC control box 160, the water pump 140 and the solenoid valve 122 will start intermittently. After the solenoid valve 122 is opened, the liquid water in the curing box 120 will enter the water tank 110 (the liquid water in the curing box 120 is negligible compared to the water volume in the water tank 110, so it will not have a great impact on the water temperature in the water tank 110). Then the water pump 140 pumps the qualified liquid water in the water tank 110 to the curing box 120. During this process of pumping the liquid water, since the water volume is small and will not exceed the top height of the retention box 130, the liquid water will no longer enter the retention box 130, thus maintaining the stability in the retention box 130 and meeting the specification requirements. At the same time, the water in the curing box 120 and the water in the retention box 130 conduct heat exchange through the outer wall of the retention box 130, so that the water in the retention box 130 always meets the curing requirements.

[0024] As can be seen from the above, in the embodiment of the present application, by setting the heat exchange device 111 and the temperature sensor 112 and interacting with the PLC control box 160, the heat exchange device 111 can change the temperature of the water in the water tank 110 according to the temperature detected by the temperature sensor 112, so that the water in the water tank 110 always meets the curing requirements. The present application also sets the retention box 130 and the curing box 120. The retention box 130 is located inside the curing box 120 and its height is lower than that of the curing box 120. Therefore, the present application can complete the water injection into the retention box 130 by injecting water into the curing box 120, and is equipped with a liquid level sensor 123. When the water level rises to the liquid level sensor 123, the water pump 140 stops injecting water. Also, since the height of the liquid level sensor 123 is higher than that of the recording box, the retention box 130 is already filled with water at this time. On the other hand, when the external temperature changes, under the action of the water pump 140, the water in the water tank 110 enters the curing box 120, and the water in the curing box 120 flows back into the water tank 110 through the return pipe 121 to complete the exchange. After the water in the curing box 120 and the water tank 110 completes the circulation, the water temperature in the curing box 120 also meets the curing requirements. Further, after the water in the curing box 120 and the water in the retention box 130 exchange heat, the water temperature in the retention box 130 will also meet the curing requirements, and the water flow in the retention box 130 will not be disturbed during this process, and the water flow in the retention box 130 remains stagnant water, meeting the specification requirements.

[0025] In some embodiments, two handles 131 are symmetrically arranged on the outer side wall of the retention box 130. In the embodiment of the present application, by setting the handles 131, it is convenient for the operator to take out the retention box 130 for slag cleaning (concrete test blocks may "peel off" and generate slag during the curing process).

[0026] In some embodiments, a plurality of strip-shaped support sleepers 124 are arranged on the inner bottom wall of the curing box 120, and the plurality of support sleepers 124 are arranged at equal intervals in the curing box 120. Since the retention box 130 will have a large gravity after placing the concrete test blocks, the embodiment of the present application sets the sleepers to prevent the retention box 130 from crushing the curing box 120.

[0027] In some embodiments, a nameplate box 125 is arranged on the outer side wall of the curing box 120. The nameplate box 125 is a box structure with an open top, and the side wall of the nameplate box 125 away from the curing box 120 is made of transparent material. In the embodiment of the present application, by setting the nameplate box 125, the operator can insert the nameplate marked with the information of the concrete test block into the nameplate box, and since the outside of the curing box 120 is transparent, the operator can conveniently view the corresponding nameplate.

[0028] In some embodiments, a sunshade 150 is included. The sunshade 150 is disposed on the top of a plurality of maintenance boxes 120. A support rod 151 is connected to the bottom of the sunshade 150. The bottom of the support rod 151 is screwed to the top of the water tank 110 through a threaded sleeve 152. In the embodiments of the present application, by providing the sunshade 150, when the device is set outdoors, direct sunlight can be avoided, thereby reducing the heating rate of the water temperature and further reducing the evaporation rate of the water in the maintenance box 120.

[0029] In some embodiments, a water injection pipe 111 is provided on the top of the water tank 110. The water injection pipe 111 communicates with the water tank 110, and an end cap is provided on the top of the water injection pipe 111. In the embodiments of the present application, the water in the water tank 110 can be replenished through the water injection pipe 111.

[0030] In some embodiments, a plurality of universal rollers are provided at the bottom of the water tank 110. In the embodiments of the present application, by providing the universal rollers, the present application can be conveniently moved to various positions.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered within the scope of the claims and the description of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
