Description

TECHNICAL FIELD

[0002] With the continuous construction of infrastructure and the development demand of city, mass concrete is widely used in engineering construction to ensure that the construction progress can be effectively controlled and the effect of carbon reduction can be achieved. In some large infrastructure constructions at present, such as bridge, reservoir, dam and other engineering, the application of mass concrete is relatively mature, but a large amount of hydration heat will be generated in the construction process of mass concrete, and the temperature stress caused by hydration heat will lead to cracking of mass concrete, thereby directly affecting the engineering quality, and even seriously affecting the safety of engineering structure and reducing the service life of structure. In order to reduce the hydration heat of mass concrete and reduce the temperature peak, cooling water pipes are usually arranged in the concrete to take away the heat in the concrete, thereby reducing the hydration heat temperature peak and avoiding the cracking of concrete.

[0003] Among them, the conventional cooling system is usually composed of cooling water tank, cooling water pipe, booster pump, control valve, water distributor and water meter and other parts, and in the working process of the cooling system, the circulating water is mainly provided by the cooling water tank to ensure the normal operation of the whole cooling system, the cooling water pipe is used for heat exchange with the concrete to take away the heat in the concrete by low temperature water in the pipe, the booster pump is used to provide the flow force of water flow, and the control valve is used to adjust the flow rate of circulating water, and the water meter is used to monitor the actual rate of water flow to ensure the smooth operation of the cooling system. But whether the circulating water in the cooling water tank is sufficient is one of the main factors affecting the normal work of the cooling system, that is, whether the water in the tank can meet the normal water circulation demand and the accurate control of water supplement in the process is very important.

[0004] Because the cooling water tank is generally made of steel in circular or rectangular structure, the water level in the tank cannot be directly observed, and at present, a back cage ladder is mainly arranged on the side wall of the tank for manual climbing for inspection to realize real-time viewing of the remaining water quantity in the tank. However, for the engineering with large concrete quantity, more water is needed, and the number of cooling water tanks is also more, and the height of each tank is also higher, so manual repeated climbing is needed, which not only has high frequency and safety hazard, but also cannot quantitatively and accurately reflect the remaining water quantity in the tank by manual naked eye observation in the observation process. Therefore, how to match the height of the cooling water tank with the monitoring device and realize real-time reflection of the change of water storage quantity in the tank to keep the circulating water in the reasonable range and avoid manual observation is a problem to be solved in the field.

Through the principle of communicating vessels, the liquid level height in the monitoring pipe is the same as the liquid level height in the water inlet tank 200 or the water outlet tank 300, and then it is convenient for the operator to observe.

[0046] Further, the filter screen is arranged in the lower connecting assembly in the embodiment, so that the water 100 in the water inlet tank 200 or the water outlet tank 300 can enter the monitoring pipe after being filtered by the filter screen. In this way, it can avoid the impurities such as silt entering the monitoring pipe to affect the monitoring result, and then improve the measurement accuracy of the monitoring pipe, so that the operator can master the water amount in the two tanks in real time, and combine with the corresponding water temperature and other conditions to supplement or discharge the cooling water in time to achieve the goal of subsequent precise control of cooling.

[0047] Specifically, the lower connecting assembly in the embodiment is provided with a first lower connecting assembly 11 and a second lower connecting assembly 13, the upper connecting assembly is provided with a first upper connecting assembly 12 and a second upper connecting assembly 14, and the monitoring pipe is provided with a first monitoring pipe 21 and a second monitoring pipe 22. Exemplarily, the first lower connecting assembly 11, the first upper connecting assembly 12 and the first monitoring pipe 21 form a group for water level observation of the water inlet tank 200 in the embodiment. Correspondingly, the second lower connecting assembly 13, the second upper connecting assembly 14 and the second monitoring pipe 22 form a group for water level observation of the water outlet tank 300. Further, the first upper connecting assembly 12 and the second upper connecting assembly 14 are both lower than the top opening of the water inlet tank 200 and the water outlet tank 300, so that the real-time change of the water level in the tank can be monitored to the maximum extent.

Specifically, the ball valve 114 and the ball valve switch 115 are arranged between the sealing space and the communication channel, and the ball valve switch 115 is used to control the opening and closing of the ball valve 114, so that the sealing space and the communication channel are correspondingly communicated and separated, and the filter screen is arranged in the sealing space to filter the water 100 in the water inlet tank 200. In the embodiment, the communication channel is communicated with the inside of the water inlet tank 200, and the sealing space is communicated with the inside of the first monitoring pipe 21.

Specifically, the connecting shell 113 is fixed on the water inlet tank 200 by welding. When the first lower connecting assembly 11 is blocked, and the monitoring result of the first monitoring pipe 21 is inaccurate or cannot be monitored, the ball valve 114 is tightened by the ball valve switch 115 to close the ball valve 114, so as to separate the sealed space and the communication passage, then the sealing cover 111 is removed, and the outer filter screen 101 and the inner filter screen 102 are sequentially removed for cleaning, the sundries and silt in the sealed shell 112 are cleaned, then the outer filter screen 101 and the inner filter screen 102 are reinstalled, the sealing cover 111 is installed, the ball valve 114 is loosened by the ball valve switch 115 to open the ball valve 114, so as to communicate the sealed space and the communication passage, so that the first monitoring pipe 21 can restore the monitoring effect, and the whole maintenance process will not affect the internal operation of the water inlet tank 200. Correspondingly, the second lower connecting assembly 13 is the same as the first lower connecting assembly 11 in structure, and can filter the water in the water outlet tank 300, and can be independently maintained to realize the normal monitoring of the second monitoring pipe 22.
