Description

Technical Field

[0001] The utility model relates to the technical field of condenser cleaning, in particular to a shellfish cleaning device for the bottom wall of a condenser water chamber. Background Art

[0002] In seawater power generation units, seawater is used as circulating water for the condenser. During this process, shellfish in the seawater will enter the condenser along with the circulating water. The reproduction rate of shellfish is very fast, and the condenser is a closed environment relative to seawater, which provides great convenience for the survival of shellfish. Shellfish can easily absorb and reproduce in the condenser.

[0003] As we all know, shellfish have a strong adsorption capacity and are difficult to eliminate through high-pressure washing alone. Killing shellfish with chemical agents can easily cause pollution to the surrounding seawater. Therefore, these methods are difficult to be effective or difficult to implement.

[0004] It has been observed that the bottom wall of the water chamber in the condenser, located near the water outlet, is the main area for the massive reproduction of shellfish. The surface of this area is smooth, without any obstruction, and only retains the water outlet. It is a favorable environment for the reproduction of shellfish. In order to solve the problem of cleaning shellfish in this area, it is urgently necessary to design a cleaning device to achieve the cleaning of the bottom wall environment of the condenser water chamber.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0006] The utility model aims to provide a cleaning machine with high cleaning efficiency, automatic regular cleaning and no pollution in view of the deficiencies in the prior art.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a shellfish cleaning device for the bottom wall of a condenser water chamber, used in a condenser water chamber, comprising a moving mechanism, a scraping mechanism, a water spraying mechanism and a control host;

[0008] The moving mechanism is installed based on the condenser water chamber and is used to make reciprocating motion along the bottom wall of the condenser water chamber;

[0009] The scraping mechanism is installed at the action end of the moving mechanism and is driven by the moving mechanism to scrape the bottom wall of the condenser water chamber;

[0010] The water spraying mechanism is installed on the action end of the moving mechanism or the scraping mechanism, and sprays water toward the bottom wall of the condenser water chamber as the scraping mechanism moves;

[0011] The control host is connected to the moving mechanism and the water spraying mechanism in a wired or wireless manner, and is used to control the working states of the moving mechanism and the water spraying mechanism.

[0012] Preferably, the moving mechanism includes a guide shaft installed across the two side walls of the condenser water chamber and a linear reciprocating motion mechanism running on the guide shaft.

[0013] Preferably, the linear reciprocating motion mechanism comprises a linear motor or an electrically controlled lead screw mechanism or a linear slide, and the linear motor or the electrically controlled lead screw mechanism or the linear slide performs linear reciprocating motion along a guide shaft, and the linear reciprocating motion mechanism is designed with a waterproof structure.

[0014] Preferably, the scraping and brushing mechanism is installed on the action end of the linear reciprocating motion mechanism through a connecting rod, and the scraping and brushing mechanism includes a mounting frame, a scraper bayonet arranged at the bottom end of the mounting frame, and a scraper installed in the scraper bayonet, and the number of the scraper bayonet and the number of the scraper bayonet are both at least one.

[0015] Preferably, the interior of the connecting rod is a hollow pipe, and the water spraying mechanism includes a plurality of nozzles installed at the bottom end of the connecting rod and a water inlet pipe connected to the upper part of the connecting rod, and the nozzles and the water inlet pipe are connected through the hollow pipe in the connecting rod.

[0016] Preferably, the nozzle is tilted outwardly with the connecting rod as a reference, so that the spraying direction of the nozzle is toward the lower outside.

[0017] Preferably, an electrically-controlled lifting unit is provided at the top end of the connecting rod, and the electrically-controlled lifting unit includes an electrically-controlled telescopic rod or an electrically-controlled swing rod.

[0018] Preferably, a discharge port is provided on the bottom wall of the condenser water chamber, and a suction device is provided below the discharge port.

[0019] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0020] The device is installed in the lower area of ​​the condenser water chamber. The scraping mechanism is carried by the moving mechanism to scrape the bottom wall of the condenser water chamber to remove the shellfish attached thereon and discharge them into the outlet at the lower end of the condenser water chamber along with the water flow, thereby maintaining the cleanliness of the bottom wall of the condenser water chamber.

[0021] Furthermore, the water spray mechanism has two functions. The first function is to inject a certain amount of seawater into the condenser water chamber. The shellfish move because they feel comfortable in the seawater environment. During the floating process, the adsorption on the bottom wall of the condenser water chamber is reduced, thereby making the scraping operation of the scraping mechanism easier. The other function is to rinse the bottom wall after scraping the shellfish to wash away the scraped shellfish.

[0022] Furthermore, a suction device is provided to extract the scraped and brushed shellfish in cooperation with a certain amount of accumulated seawater. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0028] like Figure 1-Figure 3 As shown, a shellfish cleaning device for the bottom wall of a condenser water chamber is used for a condenser water chamber 1, and includes a moving mechanism 2, a scraping mechanism 3, a water spraying mechanism 4 and a control host.

[0029] The moving mechanism 2 is installed based on the condenser water chamber 1, and is used to make reciprocating motion along the bottom wall of the condenser water chamber 1. Specifically, in this embodiment, the moving mechanism 2 includes a guide shaft 21 installed across the two side walls of the condenser water chamber and a linear reciprocating motion mechanism 22 running on the guide shaft 21. The linear reciprocating motion mechanism 22 includes a linear motor or an electric-controlled screw mechanism or a linear slide. The linear motor or the electric-controlled screw mechanism or the linear slide makes linear reciprocating motion along the guide shaft 21. The linear reciprocating motion mechanism is designed with a waterproof structure.

[0030] The scraping mechanism 3 is installed at the action end of the moving mechanism 2, and is driven by the moving mechanism 2 to scrape the bottom wall of the condenser water chamber 1. In this embodiment, the scraping mechanism 3 is installed at the action end of the linear reciprocating motion mechanism 2 through a connecting rod 31. The scraping mechanism 3 includes a mounting frame 32, a scraper bayonet 33 arranged at the bottom end of the mounting frame 32, and a scraper 34 installed in the scraper bayonet 33. The number of the scraper bayonet 33 and the number of the scraper 34 are both at least one. In actual applications, the coverage area of ​​the scraper 34 can cover the entire bottom wall of the condenser water chamber 1.

[0031] The water spraying mechanism 4 is installed on the action end of the moving mechanism 2 or the scraping mechanism 3, and moves with the scraping mechanism 3 to spray water toward the bottom wall of the condenser water chamber 1. In this embodiment, the interior of the connecting rod 31 is a hollow pipe. The water spraying mechanism 4 includes a plurality of nozzles 41 installed at the bottom end of the connecting rod and a water inlet pipe 42 connected to the upper part of the connecting rod 31. The nozzles 41 and the water inlet pipe 42 are connected through the hollow pipe in the connecting rod 31. The nozzles 41 are tilted outward with respect to the connecting rod 31 so that the spraying direction of the nozzles 41 is toward the lower outside.

[0032] The control host (not shown in the figure) is connected to the moving mechanism and the water spraying mechanism in a wired or wireless manner, and is used to control the working status of the moving mechanism and the water spraying mechanism.

[0033] In a preferred embodiment, in order to improve flexibility and reduce dead angles, an electric-controlled lifting unit is provided at the top of the connecting rod. The electric-controlled lifting unit includes an electric-controlled telescopic rod or an electric-controlled swing rod, which rises to a certain height at an appropriate position to bypass obstacles or prevent the swept shellfish from being accumulated in the corners. By lifting the action, the accumulated shellfish carcasses are bypassed without affecting the shellfish carcasses from being washed away.

[0034] In a preferred embodiment, a discharge port is provided on the bottom wall of the condenser water chamber 1, and a suction device 5, such as a suction pump, is provided below the discharge port to provide a certain suction force to quickly discharge the produced shellfish carcasses.

[0035] Brief description of working process:

[0036] Set the working frequency and working time in the control host, and then execute it according to the plan.

[0037] When the condenser water chamber is idle, the device is started to inject seawater into the bottom of the condenser water chamber through the water inlet mechanism. At the same time, or after a certain amount of seawater is injected, the moving mechanism drives the scraping and brushing mechanism to make horizontal reciprocating motion along the bottom wall of the condenser water chamber, and the shellfish on the bottom wall are scraped off by the scraper. After a period of work, the drain port at the bottom of the condenser water chamber is opened, and the shellfish carcasses flow out with the water flow into the drain port. During this process, the water spraying mechanism and the scraping and brushing mechanism can continue to work to assist in the discharge of the shellfish carcasses.

[0038] Through regular cleaning work, the cleanliness of the bottom wall of the condenser is ensured.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
